SUBJECT TO COMPLETION, DATED JULY 18, 2013

16,279,070 American Depositary Shares

Graña y Montero S.A.A.

Representing 81,395,350 Common Shares

This is an initial public offering of 16,279,070 American depositary shares, or ADSs, of Graña y Montero S.A.A. Each ADS represents five common shares.

We anticipate that the initial public offering price will be between US$19.70 and US$23.30 per ADS (equivalent to approximately S/.10.88 and S/.12.87 per common share, based on the exchange rate on July 16, 2013). We have applied to have the ADSs listed on the New York Stock Exchange under the symbol “GRAM”. Our common shares are listed on the Lima Stock Exchange (Bolsa de Valores de Lima) under the symbol “GRAMONC1”. On July 16, 2013, the last reported sales price of our common shares on the Lima Stock Exchange was S/.11.15 per common share (equivalent to approximately US$20.20 per ADS based on the exchange rate on such date).

We have granted the underwriters an option for a period of 30 days to purchase from us a maximum of 2,441,860 additional ADSs, representing 12,209,300 common shares, to cover over-allotments of ADSs.

Investing in the ADSs involves risks. See “Risk Factors” beginning on page 20.

For information on our recent developments, see “Summary—Recent Developments” beginning on page 11.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Neither the ADSs nor the offering has been or will be registered in the Republic of Peru and therefore are not and will not be subject to Peruvian laws applicable to public offerings in Peru. The information contained in this prospectus has not been approved or disapproved by the Peruvian Securities Commission (Superintendencia del Mercado de Valores). The ADSs may not be offered or sold in Peru except in compliance with the securities laws of Peru.

Delivery of the ADSs will be made on or about                     , 2013.

Through and including                     , 2013 (the 25th day after the date of this prospectus), U.S. federal securities law requires all dealers that effect transactions in our ADSs, whether or not participating in this offering, to deliver a prospectus. This requirement is in addition to the dealers’ obligation to deliver a prospectus when acting as underwriters and with respect to their unsold allotments or subscription.

This prospectus has been prepared on the basis that all offers of ADSs in any Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”) will be made pursuant to an exemption under the Prospectus Directive from the requirement to produce a prospectus for offers of the ADSs. Accordingly, any person making or intending to make any offer of ADSs within the European Economic Area that are the subject of the offering contemplated in this prospectus should only do so in circumstances in which no obligation arises for us or the underwriters to produce a prospectus for such offer. Neither we nor the underwriters have authorized, or hereby authorize, the making of any offer of ADSs in circumstances in which an obligation arises for us or the underwriters to publish a prospectus for such offer. “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in the Relevant Member State; and the expression “2010 PD Amending Directive” means Directive 2010/73/EU.

The distribution of this prospectus and the offering and sale of the ADSs in certain jurisdictions may be restricted by law. Persons who receive this prospectus must inform themselves about and observe any such restrictions. This prospectus does not constitute an offer of, or an invitation to purchase, any of the ADSs in any jurisdiction in which such offer or invitation would be unlawful.

PRESENTATION OF FINANCIAL AND OTHER INFORMATION

Certain Definitions

All references to “we,” “us,” “our,” “our company,” “the group” and “Graña y Montero” in this prospectus are to Graña y Montero S.A.A., a publicly-held corporation (sociedad anónima abierta) organized under the laws of Peru. In this prospectus, we refer to our principal subsidiaries as follows: (i) in our Engineering and Construction (E&C) segment: GyM S.A. as “GyM”; Stracon GyM S.A. as “Stracon GyM”; Ingeniería y Construcción Vial y Vives S.A. as “Vial y Vives”; and GMI S.A. as “GMI”; (ii) in our Infrastructure segment: Norvial S.A. as “Norvial”; Survial S.A. as “Survial”; Concesión Canchaque S.A. as “Canchaque”; GyM Ferrovías S.A. as “GyM Ferrovías”; Concesionaria La Chira S.A. as “La Chira”; and GMP S.A. as “GMP”; (iii) in our Real Estate segment: Viva GyM S.A. as “Viva GyM”; Inmobiliaria Almonte S.A.C. as “Almonte”; and (iv) in our Technical Services segment, GMD S.A. as “GMD”; Concar S.A. as “Concar”; and CAM Chile S.A. as “CAM.”

The term “U.S. dollar” and the symbol “US$” refer to the legal currency of the United States; the term “nuevo sol” and the symbol “S/.” refer to the legal currency of Peru; the term “Chilean peso” and the symbol “CLP” refer to the legal currency of Chile; and the term “Colombian peso” and the symbol “COP” refer to the legal currency of Colombia.

Financial Information

Our consolidated financial statements included in this prospectus have been prepared in nuevos soles and in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”). Our annual consolidated financial statements for the years ended December 31, 2010, 2011 and 2012 have been audited by Dongo, Soria, Gaveglio y Asociados S.C. de R.L., a member firm of PricewaterhouseCoopers in accordance with the standards of the Public Company Accounting Oversight Board (United States). We have also included in this prospectus certain financial information for years prior to 2010 which have been prepared in accordance with generally accepted accounting principles in Peru (“Peruvian GAAP”). In accordance with Peruvian law, we were required to present our financial statements under IFRS beginning with our financial statements for the year ended December 31, 2010. Peruvian GAAP differs in certain respects from IFRS. Accordingly our financial information presented in accordance with Peruvian GAAP is not directly comparable to our financial information prepared in accordance with IFRS.

We manage our business in four segments: Engineering and Construction (E&C); Infrastructure; Real Estate; and Technical Services. For information on our results of operations per our business segments, see note 5 to our audited annual consolidated financial statements and note 7 to our unaudited interim consolidated financial statements included in this prospectus.

In this prospectus, we present EBITDA, a non-GAAP financial measure. A non-GAAP financial measure is generally defined as one that purports to measure financial performance, financial position or cash flows but excludes or includes amounts that would not be so adjusted in the most comparable IFRS measure. We present EBITDA because we believe it provides investors with a supplemental measure of the financial performance of our core operations that facilitates period-to-period comparisons on a consistent basis. Our management uses EBITDA, among other measures, for internal planning and performance measurement purposes. EBITDA should not be construed as an alternative to net profit or operating profit, as an indicator of operating performance, as an alternative to cash flow provided by operating activities or as a measure of liquidity (in each case, as determined in accordance with IFRS). EBITDA, as calculated by us, may not be comparable to similarly titled measures reported by other companies. For our definition EBITDA and a reconciliation of EBITDA to the most directly comparable IFRS financial measure, see “Selected Financial Data.”

We have translated some of the nuevos soles amounts contained in this prospectus into U.S. dollars for convenience purposes only. Unless otherwise indicated or the context otherwise requires, the rate used to translate nuevos soles amounts to U.S. dollars was S/.2.589 to US$1.00, which was the exchange rate reported

ii

for March 31, 2013 by the Peruvian Superintendency of Banks, Insurance and Private Pension Fund Administrators (Superintendencia de Banca, Seguros y AFPs, or “SBS”). We present our backlog in U.S. dollars. For contracts denominated in nuevos soles or other local currencies, amounts have been converted into U.S. dollars based on the exchange rate published by the SBS on December 31 of the corresponding year, and in the case of amounts as of March 31, 2013 based on the exchange rate published by the SBS on such date. When we present our ratios of backlog and revenues in this prospectus, we similarly convert our revenues, which are reported in nuevos soles, into U.S. dollars based on the exchange rate reported for December 31 of the corresponding year. For conversions of macroeconomic indicators (particularly in “Industry” in this prospectus), average annual exchange rates for the currencies of each of the countries addressed are used. The Federal Reserve Bank of New York does not report a noon buying rate for nuevos soles. The U.S. dollar equivalent information presented in this prospectus is provided solely for convenience of investors and should not be construed as implying that the nuevos soles or other currency amounts represent, or could have been or could be converted into, U.S. dollars at such rates or at any other rate. See “Exchange Rates” for information regarding historical exchange rates of nuevos soles to U.S. dollars.

Certain figures included in this prospectus have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be arithmetic aggregations of the figures that precede them.

Backlog

This prospectus includes our backlog for our Engineering and Construction, Infrastructure, Real Estate and Technical Services segments. We do not include backlog in this prospectus in our Infrastructure segment for: (i) our Norvial toll road concession because its revenues from the concession are derived from toll fees charged to vehicles using the highway, and, as a result, such revenues are dependent on vehicular traffic levels; and (ii) our Energy line of business because: (a) its revenues from hydrocarbon extraction services are dependent on the amounts of oil and gas we produce and market prices, which fluctuate significantly; (b) our revenues from our gas processing plant are dependent on the amount of gas we process and market prices for natural gas liquids, which fluctuate significantly; and (c) our revenues from our fuel storage terminal operation partially depend on the volume of fuel dispatched, such revenues are not material to our consolidated results of operations and the concession for such services is scheduled to terminate in August 2014. When we present backlog on a segment basis, we do not include eliminations that are included in our consolidated backlog. Backlog is not a measure defined by IFRS, and our methodology for determining backlog may not be comparable to the methodology used by other companies in determining their backlog. For our definition of backlog, see “Business—Backlog. See also “Risk Factors—Risk Related to Our Company—Our backlog and our ratio of historical backlog to revenues may not be reliable indicators of future revenues or profit.”

Reserves Estimates

This prospectus includes estimates for proved reserves in Blocks I and V where GMP provides hydrocarbon extraction services to Perupetro S.A. (“Perupetro”). These reserves estimates were prepared for us by Netherland, Sewell & Associates, Inc. (“NSAI”), independent petroleum engineers. For further information on these reserves estimates, see “Business—Infrastructure—Principal Infrastructure Lines of Business—Energy—Oil and Gas Production—Estimated Proved Reserves” and NSAI’s report dated May 28, 2013, filed as an exhibit to the registration statement of which this prospectus forms a part.

Market Information

We make estimates in this prospectus regarding our competitive position and market share, as well as the market size and expected growth of the engineering and construction, infrastructure, real estate and technical services industries in Peru and elsewhere in Latin America. We have made these estimates on the basis of our management’s knowledge and statistics and other information, which we believe to be the most recently available as of the date of this prospectus, from government agencies, industry professional organizations,

iii

industry publications and other sources. We believe these estimates to be accurate as of the date of this prospectus. Our director, Hugo Santa María Guzmán, is a partner in APOYO Consultoría, and our director, Roberto Abusada Salah is a director of the Peruvian Economy Institute. We paid International Data Corporation (IDC), a market intelligence firm focused on the information technology market, for their IT services market study referenced in this prospectus. We also paid Great Place to Work® Institute (“Great Place to Work”), a human resources consulting, research and training firm, for our employees to participate in their market survey referenced in this prospectus (Copyright ©2013 Great Place to Work® Institute, Inc. All rights reserved.).

In this prospectus we present gross domestic product (“GDP”) both on a nominal and real basis. Real GDP is nominal GDP adjusted to exclude the effect of inflation. Unless otherwise indicated, references to GDP are to real GDP.

Offering Information

All amounts contained in this prospectus that have been adjusted to reflect the estimated net proceeds of the offering are based upon the sale of ADSs at an assumed public offering price of US$21.50 per ADS (the mid-point of the price range set forth on the cover page of this prospectus). Unless otherwise indicated, all information contained in this prospectus assumes no exercise of the underwriters’ option to purchase up to 2,441,860 additional ADSs, representing 12,209,300 common shares, to cover over-allotments, if any.

• m means one meter, which equals approximately 3.28084 feet;

• m² means one square meter, which equals approximately 10.7630 square feet;

• km means one kilometer, which equals approximately 0.621371 miles;

• hectare means one hectare, which equals approximately 2.47105 acres;

SUMMARY

This summary highlights selected information contained in this prospectus and may not include all of the information that is important to you. For a more complete understanding of our company and this offering, you should read this entire prospectus, including “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements included in this prospectus.

Overview

We are the largest engineering and construction company in Peru as measured by revenues during 2012, and the largest publicly-traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2012, with strong complementary businesses in infrastructure, real estate and technical services.

With 80 years of operations, we have a long track record of successfully completing the engineering and construction of many of Peru’s landmark private- and public-sector infrastructure projects, such as the Lima International Airport and the Peru LNG gas liquefaction plant, and we believe we have earned a reputation for operational excellence in our markets. We have developed a highly-experienced management team, a talented pool of more than 3,500 engineers and a skilled work force that share our core corporate values of quality, professionalism, reliability and efficiency. As a company listed on the Lima Stock Exchange since 1997, we also abide by the highest corporate governance standards for listed companies in Peru.

Beginning in the mid-1980s, we leveraged our engineering and construction expertise into complementary lines of business, such as the development, ownership, operation and maintenance of infrastructure assets (including the Lima Metro, Peru’s only urban railway system), real estate development, and the provision of technical services primarily to infrastructure-related assets. We believe our business mix creates significant opportunities across our lines of business, generates more stable revenues and earnings on a consolidated basis, and provides additional financial stability to our company.

As a result of our performance in Peru, we have been requested by clients to undertake the engineering and construction of large and complex projects outside our home market, such as the Pueblo Viejo gold mine for Barrick Gold in the Dominican Republic. Through the successful execution of those projects, we have developed operational experience in other Latin American countries. We have further expanded our activities in other key markets of the region through the acquisition of businesses with solid positions in those markets. In February 2011, we acquired a controlling interest in Compañía Americana de Multiservicios (CAM), which is headquartered in Chile and provides technical services to power utility companies in Chile, Peru, Colombia and Brazil. In October 2012, we acquired a controlling interest in Vial y Vives, an engineering and construction company specializing in the Chilean mining sector, thus consolidating our strong position in the Latin American mining E&C sector. We expect to continue to selectively undertake projects and pursue acquisitions and strategic alliances in Latin America to further expand our company outside Peru, with a particular focus on Chile and Colombia.

Our Markets

We believe that Peru offers us attractive opportunities to continue to grow our businesses because of its strong macroeconomic outlook, stable political environment, solid public finances, increased private and public investments and growing middle class. Peru has experienced uninterrupted economic growth over the last 13 years (including in 2009 despite the global economic crisis). It has been South America’s fastest growing economy as measured by real GDP growth and one of only six investment grade countries worldwide with average annual real GDP growth over 6.5% from 2008 to 2012. According to the International Monetary Fund (IMF), the Peruvian economy is projected to grow at rates of 6.3% and 6.1% in 2013 and 2014, respectively.

The main drivers of Peru’s recent economic performance have been strong domestic demand and increased private and public investment, with private and public investment having grown at CAGRs of 7.1% and 11.3%, respectively, from 2008 to 2012. Despite this increase in investment, Peru still has a sizable infrastructure deficit of approximately US$90 billion, according to the Peruvian Association for the Promotion of National Infrastructure (AFIN). APOYO Consultoría, a business consultancy services company in Peru, has identified planned public and private investment in the key sectors of mining, power and energy, and infrastructure in Peru of US$62 billion between 2012 and 2016. Of these planned public and private investments, mining activity accounts for approximately 66.8%, power and energy accounts for approximately 25.4%, and infrastructure accounts for approximately 7.8%.

We believe that the main countries in Latin America outside our home market that we intend to focus on—Chile and Colombia—benefit from similar macroeconomic trends as Peru, and offer attractive growth opportunities for many of our business segments.

Our Business Segments

The following charts set forth the principal activities of each of our four business segments and their contribution to our consolidated revenues, EBITDA and net profit in U.S. dollars for 2012.

Revenues	EBITDA	Net Profit
US$2,020.8 million	US$299.6 million	US$141.5 million

Engineering and Construction

Our Engineering and Construction (E&C) segment has an 80-year operating history and is currently the largest player in Peru as measured by 2012 revenues, according to our internal estimates based on Peru: The Top 10,000 Companies 2012, a publication which ranks the top 10,000 companies in Peru by revenue. Throughout our history, we (on our own or as a majority or minority partner in joint operations) have completed projects in almost every major sector of the Peruvian economy. Some of these landmark projects include the construction of the Peru LNG gas liquefaction plant for Hunt Oil and Repsol, one of the largest foreign direct investments in Peru’s history; the engineering and construction of the 605 km Mantaro-Socabaya transmission line for Hydro Quebec, which connected the country’s electrical grids; and the expansion of the Cuajone copper mine operated by Southern Copper, the largest copper mine and smelter complex in the world at that time. We also completed the Lima Metro, and have built many of the iconic buildings in the country, including the Westin Lima Hotel and the Gran Teatro Nacional, as well as approximately 8,000 affordable housing and housing units. In addition to our activities in Peru, clients often request us to execute the engineering and construction of complex projects abroad, including the construction of the Pueblo Viejo gold mine for Barrick Gold in the Dominican Republic, the engineering and construction of the Four Seasons Hotel in Mexico City and, more recently, the construction of the tailings dam for the Mina de Cobre Panamá project developed by First Quantum Minerals, the second largest foreign investment project in Panama’s history, after the Panama Canal.

We provide E&C services mainly for private-sector projects and, to a lesser extent, for public infrastructure projects. As of March 31, 2013, approximately 81.7% of our engineering and construction backlog was contracted under cost-plus fee or unit price contractual arrangements, which we believe are less risky than lump-

4

sum and EPC contracts. Although contracting for engineering and construction usually consists of open bidding processes, we are often able to enter into direct bilateral contract negotiation with select clients, thanks to our reputation for quality of service, which helps mitigate competitive pricing pressures.

Infrastructure

We are an important toll road concessionaire in Peru, operating three toll roads. Moreover, we are the concessionaire for the Lima Metro, the largest mass-transit rail system in Peru, and a waste water treatment plant currently under construction. Additionally, we operate two producing oil fields under long-term government contracts and a gas processing plant.

Our principal toll road concession is Norvial, a 25-year concession ending in 2028 for a 183 kilometer stretch of the Panamericana Norte highway that provides the only northern highway exit from the city of Lima. Through a partnership with rail operator Ferrovías S.A.C., we were awarded the 30-year concession for the new Lima Metro, which began operations at the beginning of 2012. Under 30-year government service contracts that began in 1991, we also extract crude oil in two fields located in northwestern Peru. Our aggregate average daily production during 2012 and the first quarter 2013 was approximately 1,405 and 1,630 bbl per day, respectively. These fields had estimated proved reserves of 7,531.1 Mboe as of December 31, 2012 according to a reserve report prepared for us by Netherland, Sewell & Associates, Inc. (“NSAI”). We also own and operate a gas processing plant, with an aggregate capacity of 44 MMcf per day.

We continuously evaluate infrastructure projects and selectively participate in the bidding processes for a variety of concessions. We have been awarded, and are currently negotiating the contract for, the expansion of two major highways in Lima. The first is a 37-year concession awarded to a joint operation in which we have a 50% interest of the Via Expresa Javier Prado, a 20 km toll road that crosses the city from east to west, traversing through eight districts. This project has an estimated total completion cost of US$790 million. We were also awarded, and are currently negotiating the terms for, a 40-year concession for the Via Expresa Sur, a 4.6 km extension of one of the main roads in Lima, which crosses the city from north to south. This project has an estimated total completion cost of US$200 million.

Real Estate

Our Real Estate segment is the largest apartment building developer in Peru, in terms of number of units sold and value of sales in 2012, according to Tinsa, a market intelligence firm focused on the real estate market, and is focused on the development and sale of affordable housing and housing as well as other real estate projects. As of the date of this prospectus, we are in the process of developing 11 affordable housing projects (with an expected 160,000 m² in aggregate), five housing projects (with an expected 22,000 m² in aggregate); and five office buildings (with an expected 24,000 m² in aggregate). Currently our largest development project is Cuartel San Martín, a 68,000 m2 former military base located in Lima’s upscale Miraflores district, where we are planning a premiere multi-use development that will include higher-income housing, office towers, a shopping mall, a luxury hotel and a conference center.

We also own and sell significant land parcels in Lima, with a land bank of approximately 888 hectares as of March 31, 2013. Our 50.4% interest in Almonte, an approximately 800-hectare development project located in the southern part of the city of Lima, and one of the largest privately owned pieces of land in the Lima metropolitan area, represents our most significant land bank.

5

Technical Services

Our Technical Services segment undertakes a broad range of activities, including operation and maintenance services for infrastructure assets; information technology (IT) services, including IT outsourcing, systems integration, application outsourcing and business process outsourcing services; and electricity networks services, including installation, operation and maintenance of electrical metering systems and related infrastructure. This segment’s mid-to long-term contracts add a more stable cash flow stream to our consolidated activities.

Operating in the road operation and maintenance sector since 1994, we believe we are an industry leader in Peru in the sector, with 14 maintenance contracts for more than 5,000 km of road, in addition to the operation and maintenance of the Lima Metro. We are the second largest IT services company in Peru, as measured by 2011 revenues, according to International Data Corporation, a market intelligence firm focused on the IT market. Through our acquisition of a controlling interest in CAM from Enersis S.A. in February 2011, we provide field and specialized services in the engineering, installation, operation and management of electrical metering systems and related infrastructure, primarily for power utility companies in Chile, Peru, Colombia and Brazil.

Our Strengths

We believe our company’s strengths provide us with significant competitive advantages. Our principal strengths include the following:

Leader in fast-growing markets

We are the largest engineering and construction company in Peru as measured by revenues during 2012, and the largest publicly-traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2012. Peru is undergoing a period of unparalleled development, with over 6.5% average annual real GDP growth between 2008 and 2012 and significant private and public investments in the mining, power, oil and gas, transportation, real estate and other infrastructure sectors. We have completed some of the most complex and large-scale infrastructure projects in the country, and we believe we are an integral part of Peru’s ongoing transformation with projects that contribute to the overall economic development of the country. We believe our expertise, reputation, scale and operational capabilities in Peru position us to take advantage of the country’s favorable economic conditions and growth opportunities. We believe we are also a significant infrastructure concessionaire in Peru, the largest apartment building developer in Peru and a leading IT company in Peru.

We believe we are well-positioned to leverage our platform in the Peruvian market to continue to grow our business in other countries in Latin America, primarily Chile and Colombia. Throughout our history, we have undertaken complex E&C projects in the region and have recently completed acquisitions in Chile. Moreover, we believe we are one of the leading mining E&C companies in Latin America.

Long-standing track record and reputation for operational excellence

During our 80-year history, we have focused on the successful and on-time execution of complex projects, through our “deliver before deadline” and “lean construction” initiatives. Our extensive experience has allowed us to gain deep market knowledge and expertise, which help us better serve our clients and manage risks in our contractual arrangements. We believe we have a reputation for operational excellence, and were named among the top ten most admired companies in Peru by PwC in 2012. In addition, KPMG ranked us seventh out of 100 companies with the best reputations in Peru in 2012. We believe that our track record and the reputation we have earned in our markets are key factors in winning new and repeat business, as well as in partnering with strategic industry players and attracting top talent to our company.

6

Complementary lines of business which generate more stable cash flows and create additional business opportunities across our segments

We have expanded our company by developing complementary lines of business, many of which have become leaders in their respective markets. These lines of business create significant business opportunities across our segments, enabling us to capture a greater share of infrastructure spending, and also generate cost synergies. One example is Norvial, a toll-road concession operated within our Infrastructure segment. In addition to managing the concession, we used our E&C segment to design and construct the expansion of the highway and, once constructed, we are now using our Technical Services segment to operate and maintain the highway. In addition to increasing our levels of consolidated activity, many of these lines of business enable us to achieve more stable cash flows through medium and long-term client service contracts and concessions, which counter in part the cyclicality of the engineering and construction business.

High growth and profitability with strong financial position

Our operations have grown significantly over the last several years, with our consolidated revenues and EBITDA growing at CAGRs of 44.6% (34.9% excluding acquisitions) and 18.3% (13.6% excluding acquisitions) from 2010 to 2012, respectively. We have achieved this growth with low levels of indebtedness, relying mainly on cash flow from operations to fund our growth. In 2012, our net debt to EBITDA ratio was 0.1x, and as of March 31, 2013, our net debt amounted to S/.272.4 million (US$105.2 million). In 2012 and the first quarter of 2013, we achieved an EBITDA margin (i.e., EBITDA as a percentage of revenues) of 14.8% and 16.9%, respectively.

Robust backlog and significant additional potential projects

We have a robust backlog which amounted to US$4,165.9 million as of December 31, 2012, 67.0% higher than as of December 31, 2011, and US$4,291.3 million as of March 31, 2013, 3.0% higher than as of December 31, 2012. We believe that our backlog, which as of December 31, 2012 represented approximately 2.2x our related 2012 revenues, provides visibility as to our potential for growth in the coming years, although backlog may not always be an accurate indicator of future revenues. See “Risk Factors—Risk Related to Our Company—Our backlog and our ratio of historical backlog to revenues may not be reliable indicators of future revenues or profit.” Moreover, we believe our backlog is strategically targeted to our key end-markets. Approximately, 79.3% of our backlog as of March 31, 2013 is comprised of contracts with the private sector, strategically targeted to our key end-markets, such as mining, infrastructure, power, energy and real estate. In addition to our backlog, we also have significant potential projects in our pipeline. We have already been awarded concessions for the Via Expresa Javier Prado and Via Expresa Sur expansion projects, for which we are currently in the contract negotiation stage. We are also in the process of obtaining the necessary licenses to begin construction of our large multi-use real estate development project at Cuartel San Martín. Furthermore, we continuously evaluate bidding on contracts arising from the significant ongoing private and public investments in Latin America.

Proven ability to create and grow businesses organically and through acquisitions

We have proven our ability to extend our engineering and construction capabilities into complementary lines of business in a diverse range of industries, some of which began as innovative start-ups in response to client needs. For example, in 1984, we created a new IT business division, which grew and evolved through the years to become the second largest IT services company in Peru. Additionally, we also have successfully acquired and integrated new businesses. In February 2011, we acquired CAM, our electricity services business headquartered in Santiago, Chile, and have integrated its operations and personnel into our company, while improving its operational performance. More recently, in October 2012, we acquired Vial y Vives, an engineering and construction company specializing in the Chilean mining sector which complements our leading

7

E&C practice in the mining sector. We believe that our proven ability to create new businesses, develop businesses organically and acquire and successfully integrate new businesses into our platform is a key competitive advantage as we continue to expand our operations in Latin America.

Highly experienced management, talented engineers and skilled workforce, with shared core corporate values

Our senior management team has an average tenure within our company of approximately 19 years. In 2012, Euromoney recognized us as the second best managed company in the construction and cement sectors in Latin America, and among the five best managed companies in Peru. We motivate our management through performance-based compensation, which align their interests with those of our shareholders. In addition, through our efforts to attract, train and retain our workforce, we have built a talented team of employees, including more than 3,500 engineers. We also have access to a network of approximately 62,000 manual laborers throughout Peru that can supplement our workforce when required by our construction pipeline. Thanks to our extensive and talented team, we have the capability and scale to undertake large and complex projects in Peru and elsewhere.

We have been listed on the Lima Stock Exchange since 1997. We abide by the highest corporate governance standards in Peru, and we are one of only 17 companies in Latin America, and one of only three in Peru, that form part of the Company’s Circle, which recognizes companies for their high corporate governance standards and is sponsored by the International Finance Corporation (IFC), the Organization for Economic Co-operation and Development (OECD) and the Global Corporate Governance Forum. In addition, we have developed a strong corporate culture based on principles of high-quality, professionalism, reliability and efficiency. We employ rigorous safety standards and procedures and emphasize environmental sustainability and social responsibility.

Our Strategies

Our vision is to be “the most reliable engineering services company in Latin America.” Our key strategies to achieve this vision include the following:

Be the contractor of choice for large-scale and complex projects in Peru and other key markets

We intend to enhance our position as a contractor of choice for large-scale and complex infrastructure projects in Peru and other key markets, by (i) utilizing the scale, expertise and market knowledge we have accumulated during our 80-year operating history to strengthen and expand our E&C segment; (ii) maintaining and further developing our long-standing client relationships based on our ongoing pursuit of operational excellence; (iii) continuing to strategically partner with global industry leaders, such as Bechtel and Fluor, with complementary capabilities for specific projects that we undertake; and (iv) leveraging our expertise in the mining sector with a view to becoming the premier mining services provider throughout Latin America.

Further expand our infrastructure-related businesses to increase activity across our business segments and generate more stable cash flows

We plan to continue to expand our infrastructure-related businesses to capitalize on private and public investments in Peru, including in toll roads, airports, ports, railroads, hospitals, water utility companies, and other power and oil and gas infrastructure assets. In addition to providing more recurring and predictable cash flows, our Infrastructure segment generates additional business opportunities for our E&C and Technical Services segments.

8

Maintain highly capitalized balance sheet

We seek to maintain a prudent and sustainable capital structure and a strong financial position to allow us to capitalize on additional business opportunities as they arise. We intend to remain financially disciplined by limiting substantially all our debt incurrence to identified projects with repayment sources.

Selectively pursue international opportunities, focusing on Chile and Colombia

We intend to leverage the capabilities and experience we have in Peru, particularly providing engineering and construction services to the mining, oil and gas and infrastructure end-markets, to continue evaluating and selectively pursuing opportunities in other markets. We expect to focus our efforts primarily on Chile and Colombia, which we believe offer attractive opportunities in these end-markets. We are currently in discussions in connection with potential opportunities in line with our strategy, although we cannot assure you that we will be able to take advantage of these opportunities. We intend to evaluate other international opportunities on a case-by-case basis.

Continue fostering our core corporate values throughout the organization

We will continue to instill our core corporate values throughout our organization, while also transmitting these values to surrounding communities. We will continue to attract and develop our human capital through various training, mentorship and reward programs in order to maintain our position as the best company in Peru to learn and work in the engineering and construction field. We also seek to promote social welfare by fostering relationships with the communities that surround our areas of operation. We strive to promote our corporate values to strengthen our organization and improve our performance as well as to have a positive impact on the markets where we operate.

RISK FACTORS

Risks Related to Our Company

Global economic conditions could adversely affect our financial performance

The global financial crisis and ensuing global recession in 2008 and 2009 had a significant adverse effect on the development of large-scale infrastructure and real estate projects worldwide. The current sovereign crisis in Europe, coupled with the slow economic recovery in the United States, has generated economic uncertainty which could adversely affect private- and public-sector investments. Future global economic conditions, in particular fluctuations in commodity prices and financings costs, may impact our clients’ investment decisions. Should our clients choose to postpone or suspend new investments, or delay or cancel the execution of existing projects, as a result of global economic conditions, demand for our products and services, including our backlog, would decline, which may result in a decline in revenues and in under-utilization of our capacity. In addition, our business may be impacted by adverse economic developments even after economic conditions have improved because of the lag time between when investments decisions are made and the projects are executed. Furthermore, financial difficulties suffered by our clients, joint operation partners, subcontractors or suppliers due to global economic conditions could result in payment delays or defaults, or increase our costs or adversely impact our project execution. Accordingly, a global economic downturn could have a material adverse effect on our financial performance.

We may not be able to continue the historic growth of our business

We have experienced rapid growth in our operations in recent years and our strategy is to continue to grow our operations, including through international expansion. However, we may not be able to continue to grow our business at the same pace as in recent years, or at all. While our organic revenues grew at a CAGR of 34.9% from 2010 to 2012 (under IFRS), from 2003 to 2009 our organic revenues grew at a CAGR of 16.2% (under Peruvian GAAP). In addition, our organic revenues grew 13.3% during the first quarter of 2013 compared to the first quarter of 2012. The pace at which we are able to grow our business could be adversely affected by numerous factors, some of which are beyond our control, including, among others, a slowdown in Peru’s recent rapid economic growth and its substantial investment in infrastructure, increased competition, and our capacity to increase scale and manage growth in our company.

Growth can place significant demands on our management and operating structure, and too rapid growth may overwhelm our operating capacity. In addition, sustained growth will require us to recruit a large number of talented professionals and we cannot assure you that we will be able to hire sufficient engineers or other personnel with the expertise and experience we require. Nor can we assure you that as our company continues to grow we will be able to maintain our performance standards and corporate values across our entire organization. Failure to manage our growth effectively could adversely affect the quality of our products and services, which would have a material adverse effect on our business.

We face significant competition in each of our markets

Each of the markets in which we operate is competitive. We compete on the basis of, among other factors, price, performance, product and service quality, skill and execution capability, client relations, reputation and brand, and health, safety and environmental record. We face significant competition from both local and international players. Some of these competitors may have greater resources than us or specialized expertise in certain sectors. In addition, a portion of our business is derived from open bidding processes which can be highly competitive. Certain of our markets are highly fragmented with a large number of companies competing for market share. Our competitors may be more inclined to take greater or unusual risks or accept terms and conditions in a contract that we might not deem acceptable. Moreover, we cannot assure you that we will not face new competition from industry players entering or expanding their operations in our markets. If we are unable to compete effectively, our ability to continue to grow our business or maintain our market share would be affected.

20

In addition, because one of the factors on which we generally compete is price, increased competition could impact our operating margins. Accordingly, our business and financial performance could be adversely affected by competition in our markets.

A major change in Peruvian government policies could affect our business

Our business is significantly affected by national, regional and municipal government policies and regulation, including with respect to infrastructure concessions or similar contracts to the private sector, public spending in infrastructure investment, and government housing subsidies, among others. Any adverse change in government policies with respect to these matters could result in a material adverse effect on our business and financial performance.

Social conflicts may disrupt infrastructure projects

Despite Peru’s ongoing economic growth and stabilization, high levels of poverty and unemployment and social and political tensions continue to be pervasive problems in the country. Peru has, from time to time, experienced social and political turmoil, including riots, nationwide protests, strikes and street demonstrations. In 2011 and 2012, certain regions experienced strikes and protests related mainly to the environmental impact of mining activities, which resulted in commercial disruptions. These protests led to the suspension of certain mining projects, including the suspension of a large mining project in the northern region of Cajamarca. We provided construction services in the initial phase of this project before it was suspended and intend to bid for future E&C service contracts if the project progresses. Social conflicts may disrupt, delay or suspend infrastructure projects in the future, which could have a material adverse effect on our business and financial performance.

New projects may require the prior approval of local indigenous communities

In September 2011, Peru enacted Law No. 29,785, regarding the Prior Consultation Right of Local Indigenous Communities, in accordance with the International Labor Organization Convention No. 169 (Ley del Derecho a la Consulta Previa a los Pueblos Indígenas y Originarios, Reconocido en el Convenio 169 de la Organización Internacional del Trabajo). This law establishes a prior consultation procedure (procedimiento de consulta previa) that the Peruvian government must carry out with local indigenous communities whose rights may be directly affected by new legislative or administrative measures, including the granting of certain permits or new concessions or similar contracts such as for mining, energy and oil and gas projects. Local indigenous communities do not have a veto right; upon completion of this prior consultation procedure, the Peruvian government retains the discretion to approve or reject the applicable legislative or administrative measure. We cannot assure you that these consultation procedures will not adversely affect new projects and concessions. Accordingly, our business and financial performance may be materially and adversely affected.

We may not be able to successfully expand outside of Peru

One of our key strategies is to continue to expand our operations outside of Peru, particularly in Chile and Colombia, and we expect that our international operations will become a more significant part of our consolidated business in future. We cannot assure you that we will be able to replicate our success in Peru in other countries. Our international expansion is subject to additional challenges, including: our ability to assimilate cultural differences and practices; our limited familiarity with local laws, regulators and contractors; our ability to attract and manage foreign personnel; the absence of a local workforce formed in our corporate values and familiar with our operations; competition in foreign markets, including from industry players with significantly greater local experience and reputation; and other risks specific to these countries. Many countries in Latin America have suffered significant economic, political and social crises in the past, and these events may occur again in the future. If we are unable to overcome these challenges, we may not be able to successfully expand internationally.

21

We may not be able to make successful acquisitions

Part of our strategy is to evaluate strategic acquisition opportunities to expand our operations and geographic footprint. We may not be able to identify appropriate acquisition opportunities, or, if we do, we may overpay for these acquisitions or may not otherwise be able to negotiate terms and conditions that are acceptable to us. We may also face difficulties obtaining financing to pay for acquisitions. In addition, we may not be able to obtain regulatory approvals, including antitrust approvals, required to consummate acquisitions. Furthermore, even if we are able to successfully consummate an acquisition, we may encounter challenges in integrating the acquired business effectively and profitably into our operations. The integration of an acquisition involves a number of factors that may affect our operations, including diversion of management’s attention, difficulties in retaining personnel and entry into unfamiliar markets. Acquired businesses may not achieve the levels of productivity anticipated or otherwise perform as expected. Acquisitions may bring us into businesses we have not previously conducted and expose us to additional business risks that are different from those we have traditionally experienced, including new geographic, market, operating and financial risks. Moreover, acquisitions involve special risks, including the potential assumption of unanticipated liabilities and contingencies. Even if such liabilities are assumed by the sellers, we may have difficulties enforcing our rights, contractual or otherwise. We cannot assure you that future acquisitions will meet our strategic objectives.

Our backlog and our ratio of historical backlog to revenues may not be reliable indicators of future revenues or profit

Our backlog amount is subject to revision over time and our ability to realize revenues from our backlog is subject to a number of uncertainties. Cancellations, scope adjustments or deferrals may occur, from time to time, with respect to contracts reflected in our backlog and could reduce the amount of our backlog and the revenue and profits that we actually earn. Contracts may also remain in our backlog for an extended period of time and poor performance could also impact our profit from the contracts in our backlog. In addition, our backlog is expressed in U.S. dollars based on period-end exchange rates while a significant portion of our contracts are payable in nuevos soles or other local currencies. As a result, any depreciation of local currency would diminish the amount of revenues eventually earned relative to backlog. Three contracts in particular comprise 28.9% of our backlog as of March 31, 2013, and the termination of any of these three contracts would significantly reduce our backlog and future revenues and profits. Accordingly, the amount of our backlog is not necessarily indicative of future revenues or profits related to the performance of the related contracts.

Our backlog may not grow at recent historic rates and may decline. We cannot assure you that we will be able to continue obtaining sufficient contracts in the future in number and magnitude to continue to grow our backlog. Additionally, the amount of new contracts signed can fluctuate significantly from period to period due to factors that are beyond our control.

The ratio of our historical backlog to revenues earned in subsequent years is volatile and substantially affected by a number of factors, some of which are outside our control, including levels of contract scope adjustments and our ability to enter into new contracts (which are substantially influenced by general economic conditions), delays and cancellations, foreign exchange rate movements, and our ability to increase the scale of our operations to expand the amount of work we carry out beyond that previously contracted. Accordingly, historical correlations between backlog and revenues may not recur in future periods. In particular, you should not assume that the ratio of our future E&C segment revenues for 2013 and 2014 to backlog as of December 31, 2012 that is currently expected to be realized in each of those years will be comparable to our historic ratios shown in “Business—Backlog—E&C Backlog.”

Our success depends on key personnel

Our success depends, to a significant degree, upon the services of our senior management, board of directors and other key personnel (including, among others, our Chairman and our Chief Executive Officer). Members of our management team are not subject to long-term employment agreements or non-competition agreements with

22

us. We cannot assure you that we will be successful in retaining our current senior management or members of our board of directors, nor can we assure you that, in such event, we would be able to find suitable replacements. The loss of the services of some of our senior management or members of our board of directors could have a material adverse effect on our business and financial performance. In addition, the success of our business depends on our ongoing ability to attract, train and retain qualified engineers and other personnel. In recent years, the availability in Peru of qualified personnel who have the necessary expertise and experience has been lower than demand and, therefore, competition for human resources has become intense. We cannot assure that we will be able to hire and retain the number of qualified personnel required to meet the needs of, or to grow, our business. If we are unable to attract, train and retain the qualified personnel that we require at reasonable cost, our business and financial performance could be adversely affected.

Our success depends, to a large extent, on our reputation for the quality, reliability, timely delivery and safety of our products and services

We believe our track record and reputation are key factors in our clients’ evaluation of whether to engage our services and purchase our products, encouraging key industry players to partner with us, and recruiting and retaining talented personnel to our company. Our reputation is based, to a large extent, on the quality, reliability, timeliness and safety of our products and services. If our products do not meet expected standards or we fail to meet our deadlines, our relationship with our clients and partners could suffer, the reputation of our company could be adversely affected, we may not be invited to new bidding processes and our ability to capture new business could be severely diminished.

The nature of our business exposes us to potential liability claims and contract disputes

We may be subject to a variety of legal or administrative proceedings, liability claims or contract disputes. The government, clients and other third parties may present claims against us for injury or damage caused, directly or indirectly, by our operations, for example for alleged failures in our engineering and construction, the operation of our infrastructure concessions (such as our toll roads or the Lima Metro), and real estate developments we sell. Although we have adopted a range of insurance, risk management and risk avoidance programs designed to reduce potential liabilities, a catastrophic event resulting from the services we have performed or products we have provided could result in significant professional or product liability, warranty or other claims against us as well as reputational harm, especially if public safety is impacted. We may in the future be named as a defendant in legal proceedings where our clients or third parties may make a claim for damages or other remedies with respect to our projects or other matters. Any liability not covered by our insurance, or in excess of our insurance limits, could result in a significant loss for us, which may affect our financial performance.

We are susceptible to operational risks that could affect our business and financial performance

Our business is subject to numerous industry-specific operational risks, including natural disasters, adverse weather conditions, operator error or other accidents, mechanical and technical failures, explosions and other events, many of which are beyond our control. Such occurrences could result in injury or loss of life, severe damage to and destruction of property and equipment, business interruption, pollution and other environmental damage, clean-up responsibilities, regulatory requirements, investigations and penalties, and potential liability claims and contractual disputes. In addition, such occurrences could materially impact our reputation. Although we maintain comprehensive insurance covering our assets and operations at levels that our management believes to be adequate, our insurance coverage will not be sufficient in all circumstances or to protect against all hazards. The occurrence of such an operational risk could have a material adverse effect on our business and financial performance.

23

Deterioration in our safety record could adversely affect our business and financial performance

Our ability to retain existing clients and attract new business is dependent on our ability to safely operate our business. Existing and potential clients consider the safety record of their services providers to be of high importance in their decision to award service contracts. Some of our activities, in particular in our E&C segment, as well as our electricity networks services line of business, can be high risk by their nature. If one or more accidents were to occur at a site, the affected client may terminate or cancel our contract and may be less likely to continue to use our services. We cannot assure you that we will not experience accidents in the future, causing our safety record to deteriorate. Accidents may be more likely as we continue to grow, particularly if we are required to hire less experienced employees due to shortages of skilled labor. Moreover, often times we do not perform these activities by ourselves and accidents can happen due to errors committed by partners and subcontractors over whom we have no control. Because many of our clients require us to report our safety metrics to them as part of the bidding process and because a substantial part of our client base is comprised of major companies with high safety standards, a general deterioration in our safety record could have a material adverse impact on our business including our ability to bid for new contracts.

Any safety incidents or a deterioration in our safety record could adversely impact our ability to attract and retain qualified employees. In addition, we could also be subject to liability for damages as a result of accidents and could incur penalties or fines for violations of applicable safety laws and regulations.

Increases in the prices of energy, raw materials, equipment or wages could increase our operating costs

Our business requires significant purchases of energy, raw materials and components, including, among others, large quantities of fuel, cement and steel, as well as purchases or leases of equipment. Certain of these inputs used in our operations are susceptible to significant fluctuations in prices, over which we may have little control. The prices of some of these inputs are affected to a significant extent by the prices of commodities, such as oil and iron. Substantial increases in the prices of such commodities generally result in increases in our suppliers’ operating costs and, consequently, lead to increases in the prices they charge for their products. Moreover, we do not have long-term contracts for the supply of our key inputs, and, as result, if prices increase significantly or if we are required to find alternative suppliers, our costs to procure these inputs may increase significantly. In addition, growing demand for labor, especially when coupled with shortages of qualified employees in the countries where we operate, may result in significant wage inflation. To the extent that we are unable to pass along to our clients increases in the prices of our key inputs or increases in the wages that we must pay, our operating margins could be materially adversely impacted.

We may not be able to obtain financing on favorable terms

Our ability to undertake large investments (particularly in our Infrastructure and Real Estate segments) or consummate significant acquisitions will depend on the availability of equity and debt financing. We cannot assure you that we will be able to obtain new financings in the future on favorable terms or at all. Our ability to obtain financings will depend in part upon prevailing conditions in credit and capital markets, which are beyond our control. In 2008 and 2009, global markets suffered turmoil, which significantly constrained the availability of new financings. In addition, our ability to obtain new financing, or refinance existing debt, may at certain times be adversely affected by the cyclicality of our business, particularly our E&C segment, as has occurred in the past. Furthermore, in response to the ensuing global economic recession in 2009, many countries, in particular the United States as well as the countries where we operate, have maintained target interest rates at very low levels, and we cannot assure you that these interest rates will not rise significantly in the future, which would impact our costs of funding. If adequate funds are not available, or are not available on favorable terms, we may not be able to make future investments or take advantage of acquisitions or other opportunities.

24

We may not be able to recover on claims against clients for payment

If a client fails to pay our invoices on time or defaults in making its payments to us, we could incur significant losses. We occasionally bring claims against clients, principally the government, for delayed payments, additional costs that exceed the contract price or for amounts not included in the original contract price, including change orders. These types of claims can occur due to matters such as owner-caused delays or changes from the initial project scope, and, occasionally, they can be the subject of lengthy proceedings. When these types of events occur and unresolved claims are pending, we may invest significant working capital in projects to cover cost overruns pending the resolution of the relevant claims. A failure to promptly recover on these types of claims and change orders could have a material adverse effect on our financial performance.

If we are unable to enter into joint operations or other strategic alliances, our ability to compete for new business may be adversely affected

We may join with other companies to form joint operations or other strategic alliances to compete for a specific concession or contract, including with partners that contribute expertise in a specific field. Because a joint operation or alliance can often offer stronger combined qualifications than a company on a stand-alone basis, these arrangements can be important to the success of a particular bid. If we are unable to enter into joint operations or other strategic alliances, our ability to compete for new business may be adversely affected.

Our joint operations and other strategic alliances may be affected by disputes with, or the unsatisfactory performance by, our partners

Joint operations and other strategic alliances that we enter into as part of our business, including arrangements where operating control may be shared with unaffiliated third parties, may involve risks not otherwise present when we operate independently, including: sharing approval rights over major decisions; responsibility for our partners’ unpaid obligations or liabilities; and inconsistencies in our and our partners’ economic or business interests or goals. Any disputes between us and our partners may result in delays, litigation or operational impasses. We may also incur liabilities as a result of action taken by our partners. In addition, if we participate in joint operations or other strategic alliances where we are not the controlling party, we may have limited control over operation decisions and actions and the success of the joint operation or other strategic alliance will depend largely on the performance of our partners. These risks could adversely affect our ability to transact the business that is the subject of such joint operation or other strategic alliance, and could result in the termination of the applicable concession or contract. Under these circumstances, we may be required to make additional investments and provide additional services to ensure adequate performance and delivery. These additional obligations could result in reduced profits or, in some cases, increased liabilities or significant losses for us. In addition, failure by a partner to comply with applicable laws or regulations could negatively impact our business and, in the case of government contracts, could result in fines, suspension or even debarment from participating in bidding processes. As a result, our business and financial performance could be adversely affected by disputes involving our joint operation or other strategic alliances.

We are dependent upon third parties to complete many of our contractual obligations

We rely on third-party suppliers to provide much of the materials and equipment used in our businesses. A portion of the work performed under our infrastructure concessions and, to a lesser extent, other contracts is performed by third-party subcontractors. As a result, the timely completion and quality of our projects may depend on factors beyond our control, including the quality and timeliness of the delivery of materials supplied for use in the project and the technical skills of subcontractors hired for the project. If we are unable to find qualified suppliers or hire qualified subcontractors, our ability to meet our contractual obligations could be impaired. In addition, if the amount we are required to pay for supplies, equipment or subcontractors exceeds what we have estimated, we may suffer losses under our contract. If a supplier or a subcontractor fails to provide supplies, equipment or services as required under a negotiated arrangement for any reason, or provides supplies,

25

equipment or services that are not of an acceptable quality, we may be required to source those supplies, equipment or services on a delayed basis or at a higher price than anticipated, which could impact our financial performance. In addition, faulty materials or equipment could result in claims against us for failure to meet contractual specifications, and failure by suppliers or subcontractors to comply with applicable laws and regulations could negatively impact our reputation and our business and, in the case of government contracts, could result in fines, suspension or even debarment from participating in bidding processes. These risks may be intensified during economic downturns if these suppliers or subcontractors experience financial difficulties. As a result, our business and financial performance may be adversely affected by our dependence on third party providers.

Debarment from participating in government bidding processes would have a material adverse effect on our business and financial performance

We would face debarment from participating in government bidding processes for one to three years if we were found to have violated certain provisions of the Peruvian State Contracting Law (Ley de Contrataciones del Estado). We are required to comply with a large number of contractual obligations with the government in our business, and we cannot assure you that we will be in full compliance at all times. Moreover, such a debarment would affect the ability of our entire company (including any of our subsidiaries), and not just the line of business where the alleged violation took place, to participate in government bids under the Peruvian State Contracting Law. In December 2012, Sedapal S.A., the public utility company responsible for the supervision of the water service in Lima, provided us with notice that they had terminated one of our E&C contracts, which resulted in the elimination of approximately US$51.5 million from our backlog as of such date, alleging that we had breached the terms of the contract by failing to meet agreed-upon deadlines. We believe this termination is invalid because we had previously initiated arbitration proceedings, which are currently ongoing, relating to Sedapal’s denials of our requests for term extensions and because we had previously terminated the contract on the grounds that Sedapal breached its payment obligations to us. Although we believe the likelihood of Sedapal winning this new arbitration is remote, a negative outcome would affect our company’s, including any of our subsidiaries’, participation in government bidding processes under the Peruvian State Contracting Law. Additionally, in December 2011, SUNAT (Superintendencia Nacional de Aduanas y Administración Tributaria), the Peruvian tax and customs authority, provided us with notice that they had terminated one of GMD’s contracts in our Technical Services segment, which resulted in the elimination of approximately US$4.2 million from our backlog as of such date, alleging a number of service deficiencies. In response to SUNAT’s contract termination, we initiated an arbitration against SUNAT and SUNAT counterclaimed for the payment of performance bonds in an aggregate amount of S/.1.6 million. A negative outcome in this arbitration, if we do not resolve the dispute with SUNAT, would also affect our company’s, including any of our subsidiaries’, participation in government bidding processes under the Peruvian State Contracting Law. Furthermore, in April 2013, Perupetro initiated an administrative proceeding against a subsidiary in our E&C segment, claiming that the subsidiary had submitted a bid to provide engineering services while not being in compliance with certain technical requirements. Although we believe that the likelihood of an adverse outcome in this proceeding is remote, an adverse outcome would affect our company’s, including any of our subsidiaries’, participation in government bidding processes under the Peruvian State Contracting Law. A significant part of our revenues on a consolidated basis is derived from public sector contracts in Peru. As a result, if our company is debarred from participating in government bidding processes, our business and financial performance would be materially and adversely affected.

Failure to comply with, or changes in, laws or regulations could have a material adverse effect on our business and financial performance

We operate in highly regulated industries. Our business and financial performance depends on our and our clients’ ability to comply on a timely and efficient basis with extensive national, regional and municipal laws and regulations relating to, among other matters, environmental, health and safety, building and zoning, labor, tax and other matters. The cost of complying with these laws and regulations can be substantial. In addition, compliance with these laws and regulations can cause scheduling delays. Although we believe we are in compliance with all applicable concessions, other similar contracts, laws and regulations in all material respects,

26

we cannot assure you we have been or will be at all times in full compliance. Failure by us or our clients to comply with our concessions, similar contracts or these laws and regulations could result in a range of adverse consequences for our business, including subjecting us to significant fines, civil liabilities and criminal sanctions, requiring us to comply with costly restorative orders, the shutdown of operations, and revocation of permits and termination of concessions or similar contracts. In addition, we cannot assure you that future changes to existing laws and regulations, or stricter interpretation or enforcement of existing laws and regulations, will not impair our ability to comply with such laws and regulations or increase our compliance costs. Accordingly, existing or future regulation in our markets could have a material adverse effect on our business and financial performance.

We may be held liable for environmental damage caused by our operations

The nature of certain of our operations requires us to assume risks of causing environmental and other damages. We may be held liable for the environmental damage we cause, including the incidental consequences of human exposure to hazardous substances or other environmental damage. We may be subject to clean up costs or penalties in the event of certain discharges into the environment and/or environmental contamination and damage. Our environmental liability insurance may not be sufficient or may not apply to certain types of environmental damage. Any substantial liability for environmental damage could have a material adverse effect on our financial performance.

New environmental regulation as a result of climate change could impact our business and financial performance

Growing concerns about climate change could result in the imposition of additional or more stringent environmental requirements or regulations. For example, there are ongoing international efforts to address greenhouse emissions, such as the Kyoto Protocol, which are in various stages of negotiation and implementation. If more stringent environmental regulation is adopted in the countries where we operate, we may be obliged to incur higher expenditures than anticipated, adversely affecting our financial performance. In addition, future remediation requirements in the event that we are found responsible for environmental damage may be substantial, which could impact our financial condition. Moreover, more stringent environmental regulation could increase the costs of projects for our clients or, in some cases, prevent a project from going forward, thereby potentially reducing the demand for our services. Accordingly, new environmental regulation could have a material adverse effect on our business and financial performance.

We may not be able to effectively protect against financial market risks

Our operations are exposed to financial market risks, such as risks related to exchange rates, commodity prices and, to a lesser extent, interest rates. Fluctuations in currency, commodity prices or interest rates could adversely affect our financial performance. We cannot assure you that derivative financial instruments will protect us from the adverse effects of financial market risks. While hedging transactions are intended to reduce market risks, such transactions may expose us to other risks, such as counterparty risk. We may not be able to adequately protect ourselves against financial market risks and may not ultimately realize an economic benefit from our hedging strategy.

The loss of a key client in some of our lines of business may affect our business and financial performance

In some of our lines of business, such as our Infrastructure and Technical Services segments, a substantial amount of the revenue we receive is concentrated among a limited number of clients, including the Peruvian government. If one or more of these major clients fail or delay in paying our fees, or if there is a significant reduction or cancellation of business by one or more of these major clients, our business and financial performance may be adversely affected. In particular we cannot assure you that Enersis, from whom we acquired our electricity networks services line of business in 2011, will not reduce its use of our services. If we are not able to capture new clients to replace the loss of business from existing key clients, our financial performance may be adversely affected.

27

Our use of the percentage-of-completion method of accounting for our Engineering and Construction segment could result in a reduction of previously recorded profits

In accordance with IFRS, we measure and recognize a large portion of our revenues under the percentage-of-completion accounting methodology. This methodology allows us to recognize revenues ratably over the life of a contract, without regard to the timing of receipt of cash payments, by comparing the amount of the costs incurred to date against the total amount of costs expected to be incurred. The effect of revisions to estimated costs, and thus revenues, is recorded when the amounts are known and can be reasonably estimated. These revisions can occur at any time and could be material. On a historical basis, we believe that we have made reasonably reliable estimates of the progress towards completion on our long-term contracts. However, given the uncertainties associated with these types of contracts and inherent in the nature of some of the industries in which we operate, it is possible for actual costs to vary from estimates previously made, which may result in reductions or reversals of previously recorded profits.

Labor unrest could adversely affect our financial performance

All of our manual laborers and a portion of our employees are members of labor unions. Our practice is generally to extend benefits we offer our unionized employees to non-unionized employees. In our E&C segment, collective bargaining agreements are negotiated at two levels, on an annual basis between the Peruvian National Federation of Civil Construction and the Peruvian Chamber of Construction, without our direct involvement, and on a per project basis directly between the unions and us in accordance with such annual agreement. We also have collective agreements with our employees in certain of our business segments, which are also negotiated periodically. Although we consider that our relationship with unions are currently positive, we cannot assure you that we will not experience work slowdowns, work stoppages, strikes or other labor disputes in the future, which could result in the interruption or delay of our operations. Such interruptions or delays could have an adverse impact on our business, including on the cost of our projects and our ability to make timely delivery. Moreover, our operations may also be affected by labor unrest in our clients’ or our partners’ workforce.

The proceeds from our insurance policies may not be sufficient and we may not be insured against all risks

We maintain insurance coverage both as a corporate risk management strategy and in order to satisfy the requirements under certain regulations and contracts. We cannot assure you that proceeds from our insurance policies, however, will be sufficient to cover the damages resulting from any event covered by such policies. Certain risks are not covered under the terms of our insurance policies, such as interruption of operations. In such event, we may incur significant expenses to rebuild our facilities, repair or replace our equipment, or cover other damages. In addition, if any of our third party insurers fail, abruptly cancel our coverage or otherwise cannot satisfy their insurance requirements to us, then our overall risk exposure and operational expenses could be increased. Moreover, we may not be able to renew our insurance policies on favorable terms, or at all. Although we have in the past been generally able to cover our insurance needs, we cannot assure you that we will be able to secure all necessary insurance in the future.

An increase in import duties and controls may have a material adverse effect on our financial performance

Our future success depends in part on our ability to select and purchase quality mechanical instruments and equipment at attractive prices. While we have historically been able to do so, such instruments and equipment may become subject to higher import taxes than currently apply. In addition, the Peruvian antitrust authority (Instituto Nacional de Defensa de la Competencia y de la Protección de la Propriedad Intelectual, or “INDECOPI”) is currently conducting an investigation regarding potential dumping of Chinese imports, which may result in new anti-dumping laws. We cannot assure you that there will not be further increases in import taxes, changes in laws related to imports or the imposition of quotas by countries from which we import mechanical instruments and equipment, which could have a material adverse effect on our business.

28

Additional Risks Related to our Engineering and Construction Business

We are vulnerable to the cyclical nature of the end-markets we serve

Demand for our engineering and construction services is dependent on conditions in the end-markets we serve, which include, among others, the mining, power, oil and gas, transportation, real estate and other infrastructure sectors in Peru, as well as the mining sector in Chile. Consequently, our engineering and construction business is closely linked to the performance and growth of these sectors, and it is exposed to many of the risks faced by our clients operating in these sectors, over which we have no control. These industries tend to be cyclical in nature and, as a result, although downturns can impact our entire company, our engineering and construction business has historically been subject to periods of very high and low demand. For example, between 2000 and 2003, there was a significant decline in activity in the Peruvian real estate and construction sectors, which consequently affected our and our competitors’ business and financial performance during that time. Factors that can affect these sectors include, among others, macroeconomic conditions, climate conditions, the level of private and public investment, the availability of credit, changes in laws and regulations, and political and social stability. The mining and oil and gas sectors, in particular, are also driven by worldwide demand for the underlying commodities, including, among others, silver, gold, copper, oil and gas, which can be affected by such other factors as global economic conditions and geopolitical affairs. A decline in prices for minerals or oil and gas can have a significant impact on our clients’ exploration and production activities and, as a result, on their demand for our engineering and construction services. Accordingly, adverse developments in the end-markets served by our engineering and construction business could have a material adverse effect on our financial performance.

Decreases in capital investments by our clients may adversely affect the demand for our services

Our engineering and construction business is directly affected by changes in private-sector and, to a lesser extent, public-sector investments for large-scale infrastructure projects. In addition, our engineering and construction business is directly affected by the availability and cost of financings for these projects. In the markets where we operate, investments and financings for large-scale projects have historically been influenced by macroeconomic and other factors which are beyond our control, including in the case of public-sector investment, government spending levels. As a result, we cannot assure you that clients will not choose to limit or not undertake new projects or delay, suspend or cancel existing projects. Reductions in anticipated capital investments or available financing for large-scale projects could have a material adverse effect on our financial performance.

Our revenues may fluctuate based on project cycles, which we may not control

The substantial majority of the revenues from our engineering and construction business is generated from project awards, the timing of which may be unpredictable and outside of our control, especially considering the highly competitive bidding processes and complex and lengthy negotiations they involve. These processes can be impacted by a wide variety of outside factors including governmental approvals, financing contingencies and overall market and economic conditions. Moreover, because a significant portion of our revenues is generated from large-scale projects, our results of operations can fluctuate quarterly or yearly depending on whether and when project awards occur and the commencement and progress of work under awarded contracts. As a result, we are subject to the risk that revenues may not be derived from awarded projects as quickly as anticipated.

Our business may be adversely affected if we incorrectly estimate the costs of our projects

We conduct our engineering and construction business under various types of contractual arrangements where costs are estimated in advance. In some of our contracts (i.e., lump-sum, unit price and EPC) we bear the risk of some or all unanticipated cost overruns, including due to inflation or certain unforeseen events. Risks under contracts which could result in cost overruns include: difficulties in performance of our subcontractors, suppliers, or other third parties; changes in laws and regulations or difficulties in obtaining permits or other

29

approvals; unanticipated technical problems; unforeseen increases in the cost of inputs, components, equipment, labor, or the inability to obtain these on a timely basis; delays caused by weather conditions; incorrect assumptions related to productivity or scheduling estimates; and project modifications that create unanticipated costs or delays. These risks tend to be exacerbated for longer term contracts since there is increased risk that the circumstances under which we based our original bid could change. In many of our contracts, we may not be able to obtain compensation for additional work performed or expenses incurred. Our failure to estimate accurately the resources and time required to complete a project could adversely affect our profitability. Even under our cost-plus contracts, our inability to complete projects within the estimated budget could affect our relationship with our clients and negatively impact awards of future contracts. As a result, if we incorrectly estimate the costs of our projects, our business and financial performance could be adversely affected.

We may be unable to deliver our services in a timely manner

The success of our engineering and construction business depends on our ability to meet the standards and schedules required by our clients. Significant delays that prevent us from providing our services on agreed time frames could adversely affect our client relations and reputation. Delays may occur for a number of reasons, including as a result of our inability to adequately foresee the needs of our clients; delays caused by our joint operation partners, subcontractors or suppliers; insufficient production capacity; equipment failure; shortage of qualified workers; changes to customs regulations; and natural disasters. Failure to finish construction by the contractual completion date set forth in the contract could result in costs that reduce our projected profit margins, including a requirement to pay daily penalties and damages. If we are unable to meet deadlines, either due to internal problems or as a result of events over which we have no control, we may lose the trust of our clients and, therefore, experience a decrease in the demand for our services. In such event, our business and financial performance could be adversely affected.

We may not be able to obtain compensation for additional work or expenses incurred as a result of client-requested change orders

Clients often determine, after commencement of the project, to change various elements of the project. Some of our contracts may also require that clients provide us with design or engineering information or with equipment or materials to be used on the project, and, in some cases, the client may provide us with deficient design or engineering information or equipment or materials or may provide the information or equipment or materials to us later than required by the project schedule. Our project contracts generally require the client to compensate us for additional work or expenses incurred due to client requested change orders or failure of the client to provide us with specified design or engineering information or equipment or materials. Under these circumstances, we generally negotiate with the client with respect to the amount of additional time required to make these changes and the compensation to be paid to us. We are subject to the risk that we are unable to obtain, through negotiation, arbitration, litigation or otherwise, adequate amounts to compensate us for the additional work or expenses incurred by us due to client-requested change orders or failure by the client to timely provide required items. A failure to obtain adequate compensation for these matters could require us to record an adjustment to amounts of revenue and gross profit that were recognized in prior periods. Any such adjustments, if substantial, could have a material adverse effect on our financial performance.

We may have difficulty obtaining performance bonds that we require in the normal course of our operations

In our engineering and construction business, it is industry practice for customers to require performance bonds or other forms of credit enhancement to secure, among other things, bids, advance payments and performance. We cannot assure you that in the future we will not encounter difficulties in obtaining such performance bonds or credit enhancements. The Peruvian market for these types of credit instruments is small; moreover, under Peruvian banking regulations, lenders are required to impose limits on the amount of credit they extend to a group of affiliated companies. Failure to provide performance bonds or credit enhancements on terms required by clients may result in our inability to compete for or win new projects.

30

Additional Risks Related to our Infrastructure Business

A substantial or extended decline in oil prices may adversely affect our financial performance

A substantial part of the revenues of our infrastructure business depends upon prevailing prices for oil. Historically, oil prices and markets have been volatile and are likely to continue to be volatile in the future. Oil is a commodity and its price is subject to wide fluctuations in response to relatively minor changes in supply and demand for oil, market uncertainty, and a variety of additional factors beyond our control. Those factors include, among others: global demand and supply; political developments in producing regions; weather conditions; governmental regulations; international conflicts and acts of terrorism; the price and availability of alternative sources of energy; and overall local and global economic conditions. Moreover, lower oil prices may not only decrease our revenues on a per unit basis, but may also reduce the amount of oil we can produce economically, if any, and, as such, may have a negative impact on the reserves of the fields in which we operate. As result, our financial performance could be materially and adversely affected by declines in oil prices.

Our reserves estimates depend on many assumptions that may turn out to be inaccurate

The process of estimating oil and gas reserves is complex. In order to prepare the reserves estimates presented in this prospectus, we and our independent petroleum engineers must project production rates and timing of development expenditures as well as analyze available geological, geophysical, production and engineering data, and the extent, quality and reliability of this data can vary. The process also requires economic assumptions about matters such as oil prices, drilling and operating expenses, capital expenditures, taxes, and availability of funds. Therefore, estimates of reserves are inherently imprecise. Actual future production, oil and gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable reserves will most likely vary from the estimates presented in this prospectus, and those variances may be material. Any significant variance could materially affect the estimated reserves of the fields in which we operate.

Our return on our investment in our concessions may not meet estimated returns

Our return on any investment in a concession is based on the terms and conditions of the concession, its duration and the amount of capital invested as well as the amount of revenues collected, debt service costs, payment of penalties and other factors. For example, traffic volume at toll roads may be affected by a number of factors beyond our control, including security conditions; general economic conditions; demographic changes; fuel prices; reduction in commercial or industrial activities in the regions served by the roads; and natural disasters. Decreased traffic at Norvial could adversely affect our financial performance. Although some of our concessions allow for adjustments based on economic conditions, certain concessions provide that adjustment requests be approved only if certain limited events specified in our concession contracts have occurred. If a request of adjustment is not granted, our financial performance could be affected. Given these factors and the possibility that governmental authorities could implement policies that affect our contractual return on investment in a way that we did not anticipate, we cannot assure you that our return on any investment under any concession will meet our estimates.

Governmental entities may terminate prematurely our concessions and similar contracts under various circumstances, some of which are beyond our control

Our ability to continue operating our concessions and similar public-sector contracts depends on governmental authorities, which may revoke the agreement for certain reasons set forth in the relevant documentation contract and in applicable legislation, including the failure to comply with any contractual terms (including the concessionaire’s default on debt) or applicable law. Moreover, the relevant governmental authority may terminate and/or repossess a concession at any time, if, in accordance with applicable law, it determines that it is in the public interest to do so. The relevant governmental authority may also assume the operation of a concession in certain emergency situations, such as war, public disturbance or threat to national security. In addition, in the case of force majeure, the relevant governmental authority may require us to implement certain

31

changes to our operations. If the government terminates any of our concessions, under Peruvian law it is generally required to compensate us for the amount of our unrecovered investment, unless the concession is revoked pursuant to applicable law or the terms of the concession which would imply a serious breach of the concession’s terms by us. Such compensation process is likely to be time consuming and the amount paid to us may not fully compensate us. We cannot assure you that we would receive such compensation on a timely basis or in an amount equivalent to the value of our investment in a concession plus lost profits.

We are exposed to risks related to the operation and maintenance of our concessions and similar contracts

The operation and maintenance requirements under our concessions could encounter delays or cause us to exceed our budgeted costs for such projects, which could limit our ability to realize the expected return on these projects, increase our operating or capital expenses and adversely affect our business and financial performance. In addition, our operations may be adversely affected by interruptions or failures in the technology and infrastructure systems that we use to support our operations, including toll road collection and traffic measurement systems. The Lima Metro in particular may be susceptible to outages due to power loss, telecommunications failures and similar events. The failure of any of our technology systems may cause disruptions in our operations, adversely affecting our profitability. While we have business continuity plans in place to reduce the adverse impact of information technology system failures on our operations, we cannot assure you that these plans will be effective. Furthermore, accidents and natural disasters may also disrupt the construction, operation or maintenance of our projects and concessions, which could adversely affect our business and financial performance.

We may not be successful in obtaining new concessions

The market for infrastructure concessions in Peru is competitive. We compete with Peruvian and foreign companies for infrastructure concessions in Peru, some of whom may have greater financial and other resources or particular expertise pertinent to a specific concession. Moreover, our public-sector clients may face budget deficits that may prohibit the development of infrastructure concessions, which could affect our business. We may also not be able to obtain additional concessions if the government decides not to award new concessions, due to budget constraints or policy changes or because alternative financing mechanisms are used. Our inability to bid for or obtain new concessions may adversely affect our business and financial performance.

The contract with Petroperú S.A. (“Petroperú”) for our fuel storage terminal business expires in August 2014. During 2012, our fuel storage terminal business generated revenues of US$49.1 million, EBITDA of US$16.6 million and US$18.2 million in gross profit (we are entitled to 50% of the joint operation revenues, EBITDA or gross profit). Our results of operations will be adversely affected if this contract is not extended or renewed. Moreover, we cannot assure you whether or when we will undertake any of the projects that have been awarded to us but for which contract negotiations are ongoing, namely the concessions for the Via Expresa Javier Prado or Via Expresa Sur. We may not be able to negotiate contracts terms that are favorable to us or at all. In addition, these projects may suffer long delays or suspension as a result of political considerations or other factors.

Additional Risks Related to our Real Estate Business

We are exposed to risks associated with the development of real estate

Our real estate business is subject to the risks that generally affect the real estate industry, such as availability and prices of suitable land, environmental and zoning regulations, interruptions in supply and volatility of the prices of construction materials and equipment, and changes in the demand for real estate. Our real estate business is specifically affected by the following risks: macroeconomic conditions in Peru that may impact the growth of the real estate sector as a whole, particularly in the residential market, including an increase in unemployment or a decrease in wage levels; an increase in prevailing interest rates or lack of available credit; changes in government subsidies for affordable housing; unfavorable real estate market conditions, such as an

32

oversupply of residential units or scarcity of suitable land in particular areas; the level of customer interest in our new projects or the sales price per unit necessary to sell the unit may be lower than expected; customer perception of the security, convenience and attractiveness of our projects and the areas in which they are located; cost overruns, many of which may be beyond our control, that exceed our estimates and affect our profit margins, including the price of labor, land, insurance, taxes and public charges; the construction and sale of units may not be completed on schedule; bankruptcy or significant financial difficulties of large industry players, which cause a loss of confidence in the industry; and restrictions on real estate development imposed by local, regional and national laws and regulations. The occurrence of any of the above events may have a material adverse effect on our business and financial performance.

Real estate prices may not continue to rise and may decline

Real estate prices in Peru have risen significantly over the last decade. We cannot assure you that this increase in real estate prices does not represent a bubble. Real estate prices in Peru may not continue to rise or may decline significantly, particularly if financing costs rise or consumer confidence in the real estate market erodes. If real estate prices decline significantly, our business and financial performance could be materially and adversely affected.

Our business may be adversely affected if we are not able to obtain the necessary licenses and/or authorizations for our developments in due time

Real estate development requires obtaining certain licenses, authorizations and registrations. In Peru, local authorities are responsible for issuing most of the licenses that are required during the development stage, including zoning, demolition and construction licenses, among others. Currently, we have approximately 21 real estate projects in various stages of development. We have not yet initiated the administrative processes before the appropriate authorities, or such procedures are pending approval, for nine of these developments, including our Cuartel San Martín multi-use development project, as they are still in the early stages of development. A denial or an extended delay by applicable administrative authorities may render land unsuitable for development or delay the completion of planned projects, increase our costs and adversely affect our business and financial performance.

Scarcity of financing and/or an increase in interest rates could decrease the demand for real estate properties

The scarcity of financing and/or an increase in interest rates may adversely affect the ability or willingness of prospective buyers to purchase our real estate properties. In most cases, the purchasers of our residential or commercial properties finance at least part of the purchase price with mortgage loans. In 2012, 53% of our residential units was sold to purchasers who received government subsidies to finance the purchase homes. An increase in interest rates, whether as a result of market conditions or government action or otherwise, may cause a decrease in the demand for our residential and commercial properties and for land development, as well as an increase of our own financing costs, which may adversely affect our business and financial performance.

We may experience difficulties in finding desirable land and increases in the price of land may increase our cost of sales and decrease our earnings

The continued growth of our real estate business depends in large part on our ability to continue to acquire land and to do so at a reasonable cost. As more developers enter or expand their operations in the Peruvian real estate sector, land prices could rise significantly and suitable land could become scarce due to increased demand or decreased supply. A resulting rise in land prices may increase our cost of sales and decrease our earnings. We may not be able to acquire suitable land at reasonable prices in the future, which may have a negative impact on our financial performance.

33

Changing market conditions may adversely affect our ability to sell home inventories in our land and at expected prices

There is a lag between the time we acquire land and the time that we can bring the developed properties to market. Lag time varies on a project-by-project basis. As a result, we face the risk that demand for real estate may decline or that other developments may occur during this period that affect market conditions, and that we will not be able to dispose of developed properties or undeveloped land at expected prices or profit margins or within anticipated time frames or at all. Significant expenditures associated with investments in real estate, such as maintenance costs, construction costs and debt payments, cannot generally be reduced if changes in market conditions cause a decrease in expected revenues from our properties. Moreover, the market value of home inventories and undeveloped land can fluctuate significantly because of changing market conditions. As a result of these and other factors beyond our control, we may be forced to sell properties or land at a loss or for prices that generate lower profit margins than we anticipate.

Additional Risks Related to our Technical Services Business

Our engagements with clients may not be profitable or may be terminated or not renewed

The pricing and other terms of many of our client contracts in our technical services business necessarily require us to make estimates and assumptions at the time we enter into these contracts that could differ from actual results. These estimates reflect our best judgments regarding the nature of the engagement and our expected costs to provide the contracted services. Because of the competitive nature of the markets in which we operate, particularly in IT services, the risks related to errors in these estimates are heightened. Any increased or unexpected costs of unanticipated delays or complications in connection with the performance of these engagements, including delays caused by factors outside our control, could make these contracts less profitable or not profitable, which would have an adverse effect on our profit margin. Our exposure to this risk increases generally in proportion to the scope of services provided under a contract.

In addition, the success of our technical services business is dependent on our ability to retain our clients. In our electricity networks services line of business in particular, Enersis, from whom we acquired control of the business in 2011 remains a key client; however, we cannot assure you that they will continue to use our services in the future. Also, in our IT services business in particular, we may lose clients due to their conversion to in-house service providers. We are also vulnerable to reduced volumes from our clients due to business downturns or for other reasons, which can reduce the scope and price of services we provide. A contract termination by a major client could cause us to experience a higher than expected number of unassigned employees, which would affect our profitability until we are able to reduce or reallocate our personnel. We may not be able to replace any client that elects to terminate or not renew its contract with us, and the termination or non-renewal of a significant number of our agreements, or of our most important contracts, may adversely affect our business and financial performance. In addition, non-compliance on a contract with a public-sector client may lead to debarment from participating in government bidding processes and, consequently, inability to contract with other public-sector clients, not just for the line of business where the alleged violation took place, but also for all of our other businesses.

We may not be successful in obtaining new government contracts

We compete to provide services to the Peruvian government, and some of our competitors may have greater financial and other resources or particular expertise pertinent to a specific contract. In addition, we may not be able to obtain additional government service contracts if the government decides not to award additional public-sector road contracts or, to a lesser extent, contracts for the provision of IT and electrical networks services, due to budget constraints, policy changes or otherwise. Our inability to obtain new government contracts may adversely affect our business and financial performance.

34

We face risks related to the delivery of products and services by our suppliers

In the course of our IT services and electricity networks services, we depend on technology providers that may commit errors or omissions related to the delivery or the quality of equipment, services or products that are essential to our business. A significant error or failure to deliver such equipment, products or services made by one of our suppliers, particularly in our IT services business where we may have an exclusive arrangement with a specific supplier for a client, may adversely affect our business and financial performance.

Our IT security measures may be breached or compromised and we may sustain system outages

We rely on encryption, authentication technology and firewalls to provide security for confidential information, including personal data, transmitted to and by us over the internet. A breach of our network security measures could result in the misappropriation of proprietary or personal information or cause interruptions in our IT services or operations, could damage our reputation and harm our ability to deliver services to our clients. This may result in client dissatisfaction and a loss of business. Our security measures may be inadequate to prevent security breaches, and we may be required to expand significant capital and other resources to protect against the threat of security breaches and to alleviate problems caused by breaches as well as by any unplanned unavailability of our IT systems caused by other reasons, which may adversely affect our business and financial performance.

Our services may infringe upon the intellectual property rights of others

Our IT services, or third-party products we offer our clients, may infringe the intellectual property rights of third parties, and we may have infringement claims asserted against us. These claims may harm our reputation, increase our costs and prevent us from offering certain services or products. Any claims or litigation relating to intellectual property, even if ultimately decided in our favor, could be time-consuming and costly, injure our reputation or require us to enter into royalty or licensing arrangements. Any limitation on our ability to provide a service or product could result in our loss of revenue-generating opportunities and require us to incur additional expenses to develop new or modified solutions for future projects, which may adversely affect our business and financial performance.

Risks Relating to Peru

Economic, social and political developments in Peru could adversely affect our business and financial performance

The substantial majority of our operations are conducted in Peru and depend on economic and political developments in the country. As a result, our business may be materially and adversely affected by economic downturns, currency depreciation, inflation, interest rate fluctuation, government policies, regulation, taxation, social instability, political unrest, terrorism and other developments in or affecting the country, over which we have no control. In the past, Peru has experienced periods of severe economic recession, large currency devaluation and high inflation. We cannot assure you that Peru will not experience similar adverse economic developments in the future. In addition, Peru has experienced periods of political instability that has included a succession of regimes with differing economic policies and programs. Previous governments have imposed controls on prices, exchange rates, local and foreign investments and international trade, restricted the ability of companies to dismiss employees, expropriated private-sector assets and prohibited the remittance of profits to foreign investors. We cannot assure you that the Peruvian government will continue to pursue business-friendly and open-market policies that stimulate economic growth and social stability.

Fluctuations in the value of the nuevo sol could adversely affect financial performance

Fluctuations in the value of the nuevo sol relative to the U.S. dollar could adversely affect Peru’s economy. In addition, fluctuations in the value of the nuevo sol to the U.S. dollar can materially adversely affect our results of operations. In 2012, 31.2% and 56.7% of our revenues were denominated in nuevos soles and U.S. dollars,

35

respectively, whereas 47.6% and 39.0% of our costs of sales were denominated in nuevos soles and U.S. dollars, respectively. In the past the exchange rate between the nuevo sol and the U.S. dollar has fluctuated significantly. We cannot assure you that the value of nuevo sol against other currencies will not fluctuate significantly in the future, which could adversely affect the Peruvian economy and our business, financial condition and results of operations.

In addition, although Peruvian law currently imposes no restrictions on the ability to convert nuevos soles to foreign currency and transfer foreign currency outside of the country, in the 1980s and early 1990s, Peru imposed exchange controls, including controls affecting the remittance of dividends to foreign investors. We cannot assure you that exchange controls in Peru will not be implemented in the future. The imposition of exchange controls could have an adverse effect on the economy and on your ability to receive dividends from us as a holder of ADSs.

Inflation could adversely affect our financial performance

In the past, Peru has suffered through periods of hyperinflation, which have materially undermined the Peruvian economy and the government’s ability to create conditions that support economic growth. A return to a high inflation environment would also undermine Peru’s foreign competitiveness, with negative effects on the level of economic activity and employment.

As a result of reforms initiated in the 1990s, Peruvian inflation decreased significantly from four-digit inflation during the 1980s. The Peruvian economy experienced annual inflation of 2.1% in 2010, 4.7% in 2011 and 2.6% in 2012, as measured by the Peruvian Consumer Price Index (Índice de Precios al Consumidor del Perú).

If Peru experiences substantial inflation in the future, our costs of sales and administrative expenses could increase which could affect our operating margins. Inflationary pressures may lead to governmental intervention in the economy, including the introduction of government policies that may adversely affect the overall performance of the Peruvian economy. For example, in response to increased inflation, the Peruvian Central Bank, which sets the Peruvian basic interest rate, may increase or decrease the basic interest rate in an attempt to control inflation or foster economic growth.

Changes in tax laws may increase our tax burden and, as a result, negatively affect our financial performance

The Peruvian congress and government regularly implement changes to tax laws that may increase our tax burden. These changes may include modifications in our tax rates and, on occasions, the enactment of temporary taxes that in some cases have become permanent taxes. Tax reforms related to the Peruvian income tax, value added tax and tax code have recently been approved, but we are unable to estimate the impacts that these reforms may have on business. The effects of any tax reforms that could be proposed in the future and any other changes that result from the enactment of additional reforms have not been, and cannot be, quantified. However, any changes to our tax regime may result in increases in our overall costs and/or our overall compliance costs, which could negatively affect our financial performance.

Earthquakes, severe weather and other natural disasters could adversely affect our business and financial performance

Peru is located in an area that experiences seismic activity and occasionally is affected by earthquakes. For example, in 2007, an earthquake with a magnitude of 7.9 on the Richter scale struck the central coast of Peru, severally damaging the region south of Lima. Such conditions may result in physical damage to our properties and equipment, closure of one or more of our project sites and infrastructure concessions, inadequate work forces in our markets and temporary disruptions in the supply of construction materials. In addition, Peru has also experienced adverse climate conditions (due to climate change or otherwise) and adverse weather patterns, such

36

as El Niño, an oceanic and atmospheric phenomenon that causes a warming of temperatures in the Pacific Ocean, resulting in heavy rains off the coast of Peru and potentially flooding. Poor weather conditions can have significant adverse effects on our engineering and construction activities as well as on our operation and maintenance of infrastructure assets business. Any of these factors may materially adversely affect the Peruvian economy and our business and financial performance.

A resurgence of terrorism in Peru could adversely affect the Peruvian economy and, as a result, our business and results of operations

In the past, Peru experienced severe terrorist activity that reached its peak of violence against the government and private sector in the late 1980s and early 1990s. In the mid-1990s, terrorist groups suffered significant defeats, including the arrest of leaders, resulting in considerable limitations in their activities. Despite the suppression of terrorist activity, we cannot assure you that a resurgence of terrorism in Peru will not occur, or that if there is such a resurgence, it will not disrupt the economy of Peru and our business.

The Peruvian economy could be affected by adverse economic developments in regional or global markets

Financial and securities markets in Peru are influenced, to varying degrees, by economic and market conditions in regional or global markets. Although economic conditions vary from country to country, investors’ perceptions of events occurring in one country may adversely affect cash flows and securities from issuers in other countries, including Peru. For example, the Peruvian economy was adversely affected by the political and economic events that occurred in several emerging economies in the 1990s, including in Mexico in 1994, the Asian crisis in 1997, the economic crisis in Russia in 1998, the Brazilian currency devaluation in 1999 and the Argentine crisis in 2001, which affected the market value of securities issued by companies from markets throughout Latin America. In addition, Peru’s economy continues to be affected by events in the economies of its major regional partners and in developed economies that are trading partners or that affect the global economy. The 2008-2009 global economic recession, principally driven by the subprime mortgage market in the United States, substantially affected the international financial system, including Peru’s securities market and economy. Additionally, the current sovereign crisis in Europe, coupled with the slow economic recovery in the United States, may reduce the confidence of foreign investors, which may cause volatility in the securities markets and affect the ability of companies to obtain financing globally. Any interruption to the recovery of the developed economies, the continued effects of the recent global crisis, a worsening of the current crisis in Europe or a new economic or financial crisis could affect Peru’s economy, and, consequently, materially adversely affect our business and financial performance.

Risks relating to Chile, Colombia and other Latin American Countries

We face risks relating to our operations outside of Peru

Latin American economic, political and social conditions may adversely affect our business. Our financial performance may be significantly affected not only by general economic, political and social conditions in Peru but also in other markets where we operate or intend to operate, including Chile and Colombia.

These countries have suffered significant economic, political and social crises in the past, and these events may occur again in the future. We cannot predict whether changes in current administrations will result in changes in governmental policy and whether such changes will affect our business. Instability in the region has been caused by many different factors, including: significant governmental influence over local economies; substantial fluctuations in economic growth; high levels of inflation; changes in currency values; exchange controls or restrictions on expatriation of earnings; high domestic interest rates; wage and price controls; changes in governmental economic or tax policies, including retroactive changes; imposition of trade barriers, including import duties on information technology equipment; electricity rationing; liquidity of domestic capital and lending markets; unexpected changes in regulation; expropriations; and high levels of organized crime, terrorism and social conflicts, as well as overall political, social and economic instability.

Risks Relating to the Offering and our ADSs

The market price of our ADSs may fluctuate significantly, and you could lose all or part of your investment

Volatility in the market price of our ADSs may prevent you from being able to sell your ADSs at or above the price you paid for them. The market price and liquidity of the market for our ADSs may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include, among others: actual or anticipated changes in our results of operations, quarterly fluctuations, or failure to meet expectations of financial market analysts and investors; investor perceptions of our prospects or our industries; operating performance of companies comparable to us and increased competition in our industries; new laws or regulations or new interpretations of laws and regulations applicable to our business; general economic trends in Peru; catastrophic events, such as earthquakes and other natural disasters; and developments and perceptions of risks in Peru and in other countries.

You may not be able to sell ADSs you own or the common shares underlying the ADSs at the time or the price you desire because an active or liquid market for these securities may not develop

Prior to this offering, there has not been a public market for our ADSs. We have applied to list our ADSs on the New York Stock Exchange. We cannot predict whether an active liquid public trading market for our ADSs will develop or be sustained. Active, liquid trading markets generally result in lower price volatility and respond more efficiently to orders from investors to purchase or sell securities. Liquidity of a securities’ market is often a function of the volume of the underlying shares that are publicly-held by unrelated parties. Our common shares are listed on the Lima Stock Exchange. Although ADS holders are entitled to withdraw common shares underlying our ADSs from the depositary at any time, the Lima Stock Exchange in Peru is generally a less liquid trading market than the New York Stock Exchange.

Substantial sales of ADSs or common shares after this offering could cause the price of our ADSs or common shares to decrease

Significant shareholders will continue to hold a large number of our common shares after this offering. We, our directors and officers and certain of our other shareholders, collectively owning 36.76% of our common shares as of June 30, 2013, will agree with the representatives of the underwriters not to offer, sell, contract to sell or otherwise dispose of or hedge any common shares or ADSs, without the prior written consent of the representatives of the underwriters, during the 180 calendar day period following the date of the prospectus, subject to certain exceptions. After this 180 day period expires, these securities will be eligible for sale. The market price of our ADSs could decline significantly if we or our significant shareholders sell securities in our company or the market perceives that we or our significant shareholders intend to do so.

We may raise additional capital in the future through the issuance of equity securities, which may result in dilution of the interests of our shareholders

We may need to raise additional capital and may opt for obtaining such capital through the public or private placement of debt securities or securities convertible into our common shares. In the event of a public or private debt financing, or the financing through the issuance of securities convertible into our common shares, such additional funds may be obtained with the exclusion of the preemptive rights of our shareholders, including the investors in our common shares, which may dilute the percentage interests of investors in our common shares.

No shareholder or group of shareholders holds a majority of our common shares

Our directors and senior management, directly and indirectly, own approximately 36.76% of our common shares as of June 30, 2013, and our Chairman owns, directly and indirectly, 21.05% of our common shares. After giving effect to this offering, assuming full exercise of the underwriters’ over-allotment option, our directors and senior management will, directly and indirectly, own approximately 31.48% of our common shares, including

38

18.03% which will be owned, directly and indirectly, by our Chairman. No shareholder or group of shareholders currently owns a majority of our common shares. In addition, there is no shareholders’ agreement among any of our significant shareholders. Accordingly, no shareholder or group of shareholders may on its own determine the outcome of substantially all matters submitted for a vote to our shareholders. In addition, a new investor or group of investors may in the future seek to acquire a significant stake in, or control of, our company, subject to compliance with Peruvian tender offer requirements which require that a tender offer be made to all shareholders upon, among other matters, acquisition of 25%, 50% and 60% of our voting rights. If a new investor or group of investors acquires a significant stake in, or control of, our company, we cannot assure you that such investor or group of investors will not seek to change how our business is managed.

Holders of ADSs may be unable to exercise voting rights with respect to our common shares underlying the ADSs at our shareholders’ meetings

As a holder of ADSs representing common shares being held by the depositary in your name, you may exercise voting rights with respect to the common shares represented by the ADSs only in accordance with the deposit agreement relating to the ADSs. Holders of our common shares will receive notice of shareholders’ meetings through publication of a notice twenty-five days in advance, in accordance with Peruvian law, in the official gazette in Peru, a Peruvian newspaper of general circulation and the website of the Peruvian Securities Commission, and will be able to exercise their voting rights by either attending the meeting in person or voting by proxy. ADS holders will not receive notice directly from us. Instead, pursuant to the deposit agreement, we will notify the depositary, who will mail to holders of ADSs the notice of the meeting and a statement as to the manner in which voting instructions may be given. To exercise their voting rights, ADS holders must instruct the depositary how to exercise the voting rights for the common shares which underlie their ADSs. Due to these additional procedural steps involving the depositary, the process for exercising voting rights may take longer for ADS holders than for holders of our common shares.

Holders of ADSs also may not receive voting materials in time to instruct the depositary to vote the common shares underlying their ADSs. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions of the holders of ADS or for the manner of carrying out such instructions, unless such failure can be attribute to gross negligence, bad faith or willful misconduct on the part of the depositary or its agents. Accordingly, holders of ADSs may not be able to exercise voting rights, and they will have little, if any, recourse if the underlying common shares are not voted as requested.

Our shareholders’ ability to receive cash dividends may be limited

Our shareholders’ ability to receive cash dividends may be limited by the ability of the depositary to convert cash dividends paid in nuevos soles into U.S. dollars. Under the terms of our deposit agreement with the depositary for the ADSs, the depositary will convert any cash dividend or other cash distribution we pay on the common shares underlying the ADSs into U.S. dollars, if it can do so on a reasonable basis and can transfer the U.S. dollars to the United States. If this conversion is not possible or if any government approval is needed and cannot be obtained, the deposit agreement allows the depositary to distribute the foreign currency only to those ADR holders to whom it is possible to do so. If the exchange rate fluctuates significantly during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the dividend distribution.

Holders of ADSs may be unable to exercise preemptive or accretion rights with respect to the common shares underlying their ADSs

Under Peruvian corporate law, if we issue new common shares as part of a capital increase, unless otherwise agreed to by holders of 40% of our subscribed voting common shares and, provided that such capital increase does not favor, directly or indirectly, certain shareholders to the detriment of others, our shareholders will generally have the right to subscribe to a proportional number of common shares of the class held by them to maintain their existing ownership percentage, which is known as preemptive rights. In addition, shareholders are

39

entitled to the right to subscribe for the unsubscribed common shares at the end of a preemptive rights offering, on a pro rata basis, which is known as accretion rights. You may not be able to exercise the preemptive or accretion rights relating to common shares underlying your ADSs unless a registration statement under the Securities Act is effective with respect to those rights or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file a registration statement with respect to the common shares relating to these preemptive and accretion rights, and we cannot assure you that we will file any such registration statement. Unless we file a registration statement or an exemption from registration is available, you may receive only the net proceeds from the sale of your preemptive and accretion rights by the depositary or, if the preemptive and accretion rights cannot be sold, they will be allowed to lapse. As a result, U.S. holders of our ADSs may suffer dilution of their interest in our company upon future capital increases.

We are entitled to amend the deposit agreement and to change the rights of ADS holders under the terms of such agreement, without the prior consent of the ADS holders

We are entitled to amend the deposit agreement and to change the rights of the ADS holders under the terms of such agreement, without the prior consent of the ADS holders. Any change related to an increase in deposits or charges for book-entry securities services or any modification that might hinder the rights of the ADS holders will be effective within 30 days after the ADS holders have received notice of such change or modification and such holders will have no right to any compensation whatsoever.

If we are unable to implement and maintain effective internal control over financial reporting in the future, or if we fail to promptly remediate our current material weakness, our results of operations and the price of our ADSs could be adversely affected

We are not currently required to comply with Section 404 of the U.S. Sarbanes-Oxley Act of 2012 and, therefore, we have not made a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. Section 404 of the U.S. Sarbanes-Oxley Act of 2002 will require us, for our fiscal year ending December 31, 2014 and subsequent years, to document and test the effectiveness of our internal control over financial reporting in accordance with an established internal control framework and to report on our conclusion as to the effectiveness of our internal controls. It will also require an independent registered public accounting firm to test our internal control over financial reporting and to report on and attest to the effectiveness of our internal control over financial reporting. Any delays or difficulty in satisfying our requirements could adversely affect our future results of operations and the price of our ADSs. Moreover, it may cost us more than we expect to comply with these control- and procedure-related requirements. Failure to comply with Section 404 could potentially subject us to sanctions or investigations by the SEC, the New York Stock Exchange or other regulatory authorities.

Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to meet our reporting obligations. If we are unable to conclude that we have effective internal control over financial reporting, or if our independent registered public accounting firm is unable to provide us with an unqualified opinion regarding the effectiveness of our internal control over financial reporting as of December 31, 2014 and in subsequent years as required by Section 404, investors could lose confidence in the reliability of our consolidated financial statements, which could result in a decrease in the value of our ADSs.

We and our independent registered public accounting firm have identified a material weakness in our internal control over financial reporting, as a result of errors we found in our consolidated statement of cash flow for the year ended December 31, 2012. In order to present investors in this offering with our corrected cash flow statement, we have restated our audited annual consolidated financial statements included in this prospectus. These errors did not have any effect on the net increase (decrease) in cash for the year ended December 31, 2012. Furthermore, all underlying transactions were properly recorded in the 2012 statement of financial position, income statement, statement of comprehensive income and statement of changes in shareholders’ equity, which did not need to be revised or restated. For a description of the changes we made to our consolidated statement of cash flow, see note 32

40

to our audited annual consolidated financial statements included in this prospectus. A “material weakness” is a deficiency, or combination of deficiencies, in internal controls such that there is a reasonable possibility that a material misstatement in financial statements will not be prevented or detected in a timely basis. The identified material weakness is related to the insufficient training and experience of certain of our accounting personnel with respect to the application of IFRS. The measures that we intend to implement to address this material weakness include: enhancing the IFRS knowledge base of our accounting personnel; hiring additional personnel experienced in IFRS; and completing the implementation of Hyperion, an automated consolidation system. We cannot be certain that any remedial measures we take will ensure that we implement and maintain adequate internal controls over our financial reporting. In addition, we may in the future discover other areas of our internal controls that need improvement, particularly with respect to businesses that we acquire.

Peru has different corporate disclosure and accounting standards than those you may be familiar with in the United States

Financial reporting and securities disclosure requirements in Peru differ in certain significant respects from those required in the United States. There are also material differences among IFRS, Peruvian GAAP and U.S. GAAP. Accordingly, the information about us available to you will not be the same as the information available to holders of shares issued by a U.S. company. In addition, the Peruvian Securities Market Law, which governs open or publicly listed companies, such as us, imposes disclosure requirements that are more limited than those in the U.S. in certain important respects. Although Peruvian law imposes restrictions on insider trading and price manipulation, applicable Peruvian laws are different from those in the United States, and the Peruvian securities markets are not as highly regulated and supervised as the U.S. securities markets.

Our status as a foreign private issuer allows us to follow alternate standards to the corporate governance standards of the NYSE, which may limit the protections afforded to investors

We are a foreign private issuer within the meaning of the New York Stock Exchange corporate governance standards. Under New York Stock Exchange rules, a foreign private issuer may elect to comply with the practices of its home country and not to comply with certain corporate governance requirements applicable to U.S. companies with securities listed on the exchange. We currently follow certain Peruvian practices concerning corporate governance and intend to continue to do so. Accordingly, holders of our ADSs will not have the same protections afforded to shareholders of companies that are subject to all New York Stock Exchange corporate governance requirements.

For example, the New York Stock Exchange listing standards provide that the board of directors of a U.S. listed company must have a majority of independent directors at the time the company ceases to be a “controlled company.” Under Peruvian corporate governance practices, a Peruvian company is not required to have a majority of independent members on its board of directors. The listing standards for the New York Stock Exchange also require that U.S. listed companies, at the time they cease to be “controlled companies,” have a nominating/corporate governance committee and a compensation committee (in addition to an audit committee). Each of these committees must consist solely of independent directors and must have a written charter that addresses certain matters specified in the listing standards. Under Peruvian law, a Peruvian company may, but is not required to, form special governance committees, which may be composed partially or entirely of non-independent directors. In addition, New York Stock Exchange rules require the independent non-executive directors of U.S. listed companies to meet on a regular basis without management being present. There is no similar requirement under Peruvian law.

The New York Stock Exchange’s listing standards also require U.S. listed companies to adopt and disclose corporate governance guidelines. In July 2002, the Peruvian Securities Commission and a committee comprised of regulatory agencies and associations prepared and published a list of suggested non-mandatory corporate governance guidelines called the “Principles of Good Governance for Peruvian Companies.” Although we have implemented these measures, we are not legally required to comply with the corporate governance guidelines, only disclose whether or not we are in compliance.

Minority shareholders in Peru are not afforded equivalent protections as minority shareholders in other jurisdictions and investors may face difficulties in commencing judicial and arbitration proceedings against our company or the controlling shareholder

Our company is organized and existing under the laws of Peru. Accordingly, investors may face difficulties in serving process on our company, our officers and directors or our significant shareholders in the United States of certain other jurisdictions, and in enforcing decisions granted by courts located in other jurisdictions against our company, our officers and directors or our significant shareholders that are based on securities laws of jurisdictions other than Peru.

In Peru, there are no proceedings to file class action suits or shareholder derivative actions with respect to issues arising between minority shareholders and an issuer, its controlling shareholders or directors and officers. Furthermore, the procedural requirements to file actions by shareholders differ from those of other jurisdictions, such as in the United States. As a result, it may be more difficult for our minority shareholders to enforce their rights against us, our directors, officers or significant shareholders as compared to the shareholders of a U.S. company. The deposit agreement provides that the depositary has no obligation to commence or become involved in any judicial proceedings and any other legal actions relating to the ADSs or the deposit agreement, either on behalf of the ADS holders or on behalf of any other person.

Judgments of Peruvian courts with respect to our common shares will be payable only in nuevos soles

If proceedings are brought in the courts of Peru seeking to enforce our obligations in respect of the common shares, we will not be required to discharge our obligations in a currency other than nuevos soles. Under Peruvian exchange control limitations, an obligation in Peru to pay amounts denominated in a currency other than nuevos soles may be satisfied in Peruvian currency only at the exchange rate, as determined by the Peruvian Central Bank, in effect on the date the judgment is obtained, and such amounts are then adjusted to reflect exchange rate variations through the effective payment date. The then prevailing exchange rate may not afford non-Peruvian investors with full compensation for any claim arising out of or related to our obligations under the ADSs.

Our newly issued common shares from this offering will initially be represented by “certificados provisionales” for which there may not be a liquid market

In accordance with Peruvian law, our common shares will be represented by preliminary stock certificates (certificados provisionales) until the capital increase is recorded with the Peruvian public registry and new common shares are listed on the Lima Stock Exchange and registered in the CAVALI S.A. ICLV book-entry settlement system. We cannot assure you that the Peruvian public registry will not delay the recording of our capital increase. In addition, the corporate resolution authorizing the capital increase may be subject to judicial challenges or other factors that prevent or delay the recording of the capital increase with the Peruvian public registry. Once the capital increase has been recorded, we will issue common shares in exchange for the preliminary stock certificates. Only after the capital increase has been recorded with the Peruvian public registry and we have issued common shares in exchange for the preliminary stock certificates, will you be able to cancel your ADSs and withdraw the deposited common shares.

If securities or industry analysts do not actively follow our business, or if they publish unfavorable research about our business, the price and trading volume of the ADSs could decline

The trading market for the ADSs will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. If analysts do not cover our company, the trading price for the ADSs may be negatively impacted. If one or more of the analysts who covers us downgrades the ADSs or publishes unfavorable research about our business, the price of the ADSs would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for the ADSs could decrease, which could cause the price and trading volume of the ADSs to decline.

EXCHANGE RATES

The Peruvian nuevo sol is freely traded in the exchange market. Current Peruvian regulations on foreign investment allow foreign equity holders of Peruvian companies to receive and repatriate 100% of the cash dividends distributed by these companies. Non-Peruvian equity holders are allowed to purchase foreign currency at free market currency rates through any member of the Peruvian banking system and transfer such foreign currency outside Peru without restriction. Peruvian law in the past, however, has imposed restrictions on the conversion of Peruvian currency and the transfer of funds abroad, and we cannot assure you that Peruvian law will continue to permit such payments, transfers, conversions or remittances without restrictions.

The following table sets forth, for the periods indicated, certain information regarding the exchange rates for nuevos soles per U.S. dollar, as published by the SBS. The Federal Reserve Bank of New York does not report a noon buying rate for nuevos soles.

USE OF PROCEEDS

We estimate that the net proceeds to us from this offering will be approximately US$337,745,005 million, or US$389,063,745 million if the underwriters exercise the over-allotment option in full. These amounts assume an initial public offering price of US$21.50 per ADS (the midpoint of the price range set forth on the cover page of this prospectus), after deducting the estimated underwriting discounts and commissions and offering expenses payable by us, and assumes no exercise of the underwriters’ over-allotment option.

We intend to use the net proceeds from this offering for capital expenditures, including potential investments and acquisitions, and other general corporate purposes in our business segments, in order to take advantage of growth opportunities that we foresee in our markets. We currently expect to use approximately (i) 60% of the net proceeds for investments in our Infrastructure segment, (ii) 10% of the net proceeds for the purchase of land in our Real Estate segment, (iii) 20% of the net proceeds for acquisitions, and (iv) the remainder for general corporate purposes. These estimates, however, are subject to change.

We routinely evaluate new infrastructure concessions, acquisitions, land purchases and other investment opportunities that are aligned with our strategic goals. We cannot assure you that we will find opportunities that we consider to be favorable to us, whether we will be able to take advantage of such opportunities should they arise, or the timing of and funds required by such opportunities. In addition, we expect to finance these opportunities with a combination of cash on hand, net proceeds from this offering, new borrowings and/or financial contributions from partners, depending on a variety of commercial considerations at such time. Accordingly, we will have significant flexibility in applying the net proceeds from this offering. As a result, our actual use of proceeds from this offering could vary significantly from the currently expected use.

Pending application of the net proceeds, we expect to invest the proceeds in low-risk marketable securities, bank deposits, money market funds and similar investments.

CAPITALIZATION

The following table sets forth our capitalization as of March 31, 2013:

• on an actual basis; and

• as adjusted to give effect to the sale of our ADSs in the offering at an assumed initial public offering price of US$21.50 per ADS (the midpoint of the price range set forth on the cover page of this prospectus), after deducting estimated underwriting discounts and commissions and offering expenses payable by us. Estimated net proceeds from the offering were converted from U.S. dollars to nuevo soles at an exchange rate of S/.2.762 to US$1.00 as of July 16, 2013.

The as adjusted information in the table below assumes no exercise of the underwriters’ over-allotment option.

The table below should be read in conjunction with our consolidated financial statements included in this prospectus.

DILUTION

Purchasers of our ADSs in this offering will experience immediate and substantial dilution to the extent of any difference between the initial public offering price per ADS and the net book value per ADS upon the completion of the offering.

Net book value represents the amount of our total assets, less our total liabilities and excluding goodwill. Net book value per share is determined by dividing our net book value by the number of our outstanding common shares.

As of March 31, 2013, our net tangible book value was approximately S/.1,788.7 million, or S/.3.20 per common share (equivalent to US$5.74 per ADS). Based upon an assumed initial public offering price of US$21.50 per ADS (the midpoint of the price range set forth on the cover page of this prospectus), our net tangible book value would increase to S/.4.32 per common share or US$7.74 per ADS, and the immediate dilution to purchasers of our ADSs in the offering will be S/.7.68 per common share or US$13.76 per ADS or 63.98% following the offering. The following table illustrates this dilution per common share and per ADS:

	Per ADS		Per common share
Assumed initial public offering price	US$	21.50	S/.	12.00
Net tangible book value as of March 31, 2013		5.74		3.20
Dilution to new investors		13.76		7.68

If the underwriters exercise the over-allotment option in full, net tangible book value following the offering would increase to S/.4.47 per common share or US$8.00 per ADS and the immediate dilution to our purchasers of ADSs in the offering would be S/.7.54 per common share or US$13.50 per ADS.

Non-GAAP Financial Measure and Reconciliation

In this prospectus, we present EBITDA, a non-GAAP financial measure. A non-GAAP financial measure is generally defined as one that purports to measure financial performance, financial position or cash flows but excludes or includes amounts that would not be so adjusted in the most comparable IFRS measure. We define EBITDA as net profit plus: financial (expense) income, net; income tax; and depreciation and amortization. We present EBITDA because we believe it provides investors with a supplemental measure of the financial performance of our core operations that facilitates period-to-period comparisons on a consistent basis. Our management uses EBITDA, among other measures, for internal planning and performance measurement purposes. EBITDA should not be construed as an alternative to net profit or operating profit, as an indicator of operating performance, as an alternative to cash flow provided by operating activities or as a measure of liquidity (in each case, as determined in accordance with IFRS). EBITDA, as calculated by us, may not be comparable to similarly titled measures reported by other companies. The following table sets forth the reconciliation of our net profit to EBITDA on a consolidated basis.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with our consolidated financial statements included in this prospectus. Our consolidated financial statements included in this prospectus have been prepared in accordance with IFRS issued by the IASB. The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those discussed in the forward-looking statements as a result of various factors, including, without limitation, those set forth under “Forward-Looking Statements” and “Risk Factors.”

Overview

We are the largest engineering and construction company in Peru as measured by revenues during 2012, and the largest publicly traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2012, with strong complementary businesses in infrastructure, real estate and technical services. With 80 years of operations, we have a long track record of successfully completing the engineering and construction of many of the country’s landmark private and public sector infrastructure projects. Beginning in the mid-1980s, we decided to leverage our engineering and construction expertise into complementary lines of business. We have also undertaken the engineering and construction of large and complex projects outside our home market throughout our history. More recently, we decided to expand our activities into other key markets of the Latin American region through the acquisition of businesses with solid positions in those markets.

Factors Affecting Our Results of Operations

General

Peruvian and Chilean Economic Conditions

95.2%, 85.1%, 82.8% and 84.6% of our revenues in 2010, 2011, 2012 and the first quarter of 2013 were derived from activities in Peru. Accordingly, our results of operations are substantially affected by economic conditions in the country and our growth is driven in significant part by growth in the Peruvian economy. In addition, 8.0%, 12.5% and 11.7% of our revenues in 2011, 2012 and the first quarter of 2013 were derived from activities in Chile, primarily as a result of the acquisition of a controlling interest in CAM in February 2011. We expect our percentage of Chilean revenues to continue to grow as a result of our acquisition of Vial y Vives in October 2012.

The Peruvian economy has been one of the fastest growing economies globally, with the Peruvian real GDP growing at an average rate of 7.3% during the three years from 2010 to 2012 as a result of, among other factors, robust domestic demand and increased private and public investment. With increasing disposable income and an expanding middle class, private consumption grew at an average annual rate of 6.0% in real terms from 2010 to 2012. Also, during this period, private investment increased at an average annual rate of 15.8% in real terms, driven by an increase in projects primarily in the mining, oil and gas, energy, transportation, telecommunications and manufacturing sectors. Inflation in Peru, as measured by the change in the consumer price index, was 2.1% in 2010, 4.7% in 2011 and 2.6% in 2012. The nuevo sol appreciated versus the U.S. dollar by 2.8%, 4.0% and 5.4% in 2010, 2011 and 2012. Given its recent performance with regard to fiscal balance, debt/GDP ratio, net reserves and high liquidity, Peru’s sovereign debt is rated investment grade and was upgraded to BBB by S&P and Fitch in August 2011 and October 2011, respectively, and to Baa2 by Moody’s in August 2012. According to the IMF the Peruvian economy is projected to grow at rates of 6.3% and 6.1% in 2013 and 2014, respectively.

The Chilean economy grew at an average annual rate of 5.9% during the three years from 2010 to 2012 in real terms, mainly driven by strong domestic demand. Private consumption grew at an average annual rate at 8.6% in real terms during the three years from 2010 to 2012, and total fixed investment grew at an annual

59

average rate of 13.1% in real terms during this period. Inflation in Chile, as measured by the change in the consumer price index, was 3.0% in 2010, 4.4% in 2011 and 1.5% in 2012. The Chilean peso fluctuated versus the U.S. dollar, increasing by 7.5% in 2010, decreasing by 11.3% in 2011, and increasing by 8.2% in 2012. Chilean sovereign debt was rated A+ by Fitch in February 2012, AA- by S&P in December 2012 and Aa3 by Moody’s in December 2012, the highest sovereign debt ratings in Latin America. According to the IMF the Chilean economy is projected to grow at rates of 4.9% and 4.6% in 2013 and 2014, respectively.

From 2003 to 2009, our revenues grew at a CAGR of 17.2% under Peruvian GAAP, and from 2010 to 2012 our revenues grew at a CAGR of 44.6% (34.9% excluding acquisitions) under IFRS. We expect, but cannot assure you, that in the future our business will tend to grow in line with the performance of and investment in the end-markets we serve.

Fluctuations in Exchanges Rates

We estimate that in 2012, 31.2%, 56.7% and 12.1% of our revenues were denominated in nuevos soles, U.S. dollars and other currencies (principally Chilean pesos), respectively, while 47.6%, 39.0% and 13.5% of our cost of sales during the year were denominated in nuevos soles, U.S. dollars and other currencies. We estimate that in the first quarter of 2013, approximately 31.1%, 58.6% and 10.3% of our revenues were denominated in nuevos soles, U.S. dollars and other currencies, respectively, while 71.7%, 17.7% and 10.6% of our cost of sales during the first quarter of 2013 were denominated in nuevos soles, U.S. dollars and other currencies. In addition, as of March 31, 2013, 4.8%, 89.9% and 5.3% of our total debt was denominated in nuevos soles, U.S. dollars and other currencies, respectively. Accordingly, fluctuations in the value of these currencies can materially affect our results of operations. When the nuevo sol appreciates against the U.S. dollar, our operating margins tend to decrease; when the nuevo sol depreciates against the U.S. dollar, our operating margins tend to increase. Conversely, the appreciation of the nuevo sol against the U.S. dollar tends to decrease our indebtedness and financial expenses as expressed in nuevos soles; and the depreciation of the nuevo sol against the U.S. dollar tends to increase our indebtedness and financial expenses as expressed in nuevos soles. We enter into derivatives, from time to time, to hedge part of our financial exposure to currency fluctuations. The value of the nuevo sol to the U.S. dollar appreciated from 2010 to 2012, but has depreciated during 2013 to date, which is impacting our results of operations. See “Exchange Rates.”

We have included estimates of the approximate effects of fluctuations in exchange rates on our consolidated and segment revenues and costs of sales in “—Results of Operations.” These estimates were calculated based on daily average exchange rates and estimated aggregate revenues and cost of sales denominated in U.S. dollars and Chilean pesos, and were not calculated on a transaction by transaction basis. For additional information on the effect of exchange rate fluctuations on our results of operations, see “—Quantitative and Qualitative Disclosures about Market Risk—Exchange Rate Risk.”

Cost of Labor, Third Party Services and Inputs

The largest components of our costs are: labor, which in 2012 represented 32.3% of our cost of sales and 48.8% of our administrative expenses; services provided by third parties, which in 2012 represented 30.7% of our cost of sales and 20.0% of our administrative expenses; and inputs (including raw materials), which in 2012 represented 25.2% of our cost of sales. During the first quarter of 2013, labor represented 27.0% of our cost of sales and 63.4% of our administrative expenses; services provided by third parties represented 35.4% of our cost of sales and 16.6% of our administrative expenses; and inputs (including raw materials) represented 16.9% of our cost of sales. For a breakdown of our cost of sales and administrative expenses, see note 23 to our audited annual consolidated financial statements and note 14 to our unaudited interim consolidated financial statements included in this prospectus.

Our cost of labor is influenced by, among other factors, the number of our employees, as well as inflation, competition we face for personnel in each of our business segments and the availability of qualified candidates. From 2010 to 2011 our personnel charges increased by 77.1%, and from 2011 to 2012 our personnel charges

60

increased 38.1%. Services provided by third parties include: subcontracting in our E&C segment, such as carpentry work; advisory and consultancy work, including external audit and legal services; and renting of equipment. From 2010 to 2011 our costs related to services provided by third parties increased by 53.4%, and from 2011 to 2012 our costs related to services provided by third parties increased by 0.7%. The principal inputs we use are fuel, cement and steel, which in the aggregate represented a majority of our total input costs in 2012. Our costs for these inputs are affected by, among other factors, the growth of our operations, market prices, including global prices in the case of fuel, and transportation costs. We do not have long-term contracts for the supply of our key inputs. From 2010 to 2011, our input costs increased by 258.1%, and from 2011 to 2012 our input costs increased by 46.5%. These increases in our costs during the years from 2010 to 2012 were primarily due to our acquisition of a controlling interest in CAM in February 2011 and high organic growth in our business. Excluding the acquisition of CAM, our personnel charges, costs related to services provided by third parties and input costs in the aggregate increased by 57.5% in 2011 and by 28.4% in 2012.

Acquisitions

We acquired a 75.0% interest in CAM in February 2011 for US$10.8 million, after post-closing adjustments. Accordingly, CAM’s results are not reflected in our results of operations for 2010, only 10 months performance is reflected in 2011 and a full year performance is reflected in 2012. In 2012, CAM represented 12.1% of our consolidated revenues, 3.3% of our consolidated gross profit and 6.7% of our consolidated operating profit. The inclusion of CAM has increased our revenues and diversified our company in geographic terms; however, it has also impacted our consolidated gross margins as CAM’s gross margins tend to be significantly lower than those of our other business lines, reducing our consolidated gross margin by 160 basis points in 2011 and 110 basis points in 2012. In 2011, as a result of the excess of the fair value of the assets and liabilities we acquired in the CAM acquisition over the consideration paid, we recognized a gain of S/.45.2 million, which is reflected in “gain from business combination.” In 2012 and the first quarter of 2013, we reversed provisions amounting to S/.75.9 million and S/.3.9 million, respectively, relating to labor and tax contingencies and trade liabilities that we had reflected on our balance sheet in connection with the CAM acquisition because we determined that the underlying contingencies and liabilities had become remote, expired or been resolved; these reversals are reflected under “other income (expenses).” For further information, see notes 25 and 28(c) to our audited annual consolidated financial statements included in this prospectus.

In addition, we acquired a 74.0% interest in Vial y Vives in October 2012 for US$55.6 million and a 3.2% interest in Vial y Vives in June 2013 for US$1.7 million. Accordingly, Vial y Vives’ results have not been fully reflected in our historical results of operations for 2012. We expect the acquisition of Vial y Vives to further increase and diversify our revenues, in addition to complementing our expertise in the E&C mining sector; however, the historic operating margins of Vial y Vives have tended to be lower than those of our E&C segment because of its relatively higher administrative expenses. In the first quarter of 2013, we reversed provisions amounting to S/.4.6 million relating to accounts receivables and labor contingencies.

Cyclicality

Our Engineering and Construction segment is cyclical as a result of being closely linked to the conditions, performance and growth of the end-markets we serve, which include, among others, the mining, power, oil and gas, transportation, real estate and other infrastructure sectors in Peru, as well as the mining sector in Chile. These industries tend to be cyclical in nature and tend to be affected by factors such as macroeconomic conditions, climate conditions, the level of private and public investment, the availability of credit, changes in laws and regulations and political and social stability. As a result, although downturns impact our entire company, our Engineering and Construction segment has historically been subject to periods of very high and low demand. For example, between 2000 and 2003, there was a significant decline in activity in the Peruvian real estate and construction sectors, which consequently affected our and our competitors’ business and financial performance during that time. The mining and oil and gas sectors, in particular, are also driven by worldwide demand for the underlying commodities, including, among others, silver, gold, copper, oil and gas, which can be

61

affected by such other factors as global economic conditions and geopolitical affairs. Furthermore, prevailing prices and expectations about future prices for minerals or oil and gas, costs of exploration, production and delivery of product and similar factors can have a significant impact on our clients’ exploration and production activities and, as a result, on their demand for our engineering and construction services.

Our Real Estate segment is also cyclical and is significantly affected by changes in general and local economic conditions, such as employment levels and job growth, availability of financing for home buyers, interest rates, foreclosure rates, inflation, consumer confidence and housing demand. In addition, in our Infrastructure segment, our Energy line of business is cyclical and affected by global supply and demand for oil.

Seasonality

Our business, on a consolidated basis, has not historically experienced seasonality. In our Infrastructure segment, we have experienced moderate seasonality at (i) Norvial, due to heightened vehicular traffic activity during the summer season in the first quarter of the year, and (ii) GMP’s gas processing plant, which typically closes for maintenance during the rainy season in the first quarter of the year, as demand for gas is lower during this time.

Engineering and Construction

The principal driver of our E&C results is economic growth in Peru, particularly private and public investment in the country’s mining, power, oil and gas, transportation, real estate and other infrastructure sectors. See “—Peruvian and Chilean Economic Conditions.”

Appropriate pricing and budgeting of our engineering and construction projects is also key to our results of operations in our E&C segment and can be affected by such factors as competition, direct negotiations with clients as opposed to competitive bidding processes, the accuracy of our estimation of project costs and unexpected cost overruns. The types of contracts in this segment consist of cost-plus fee, unit price, lump-sum and EPC contracts. For a description of our E&C contracts, see “Business—Engineering and Construction—Contracts.” The nature of our contractual arrangements can affect our margins, both because, depending on the type of contract, the burden of cost overruns may be placed on the client or on us, and because certain contractual arrangements tend to have lower gross margins. For the years from 2010 to 2012, our E&C segment has trended towards contractual arrangements that pose less risk for us (i.e., cost-plus fee and, to a lesser extent, unit price), which provide more stability to our results but lower gross margins. The types of contractual arrangements we enter into in our E&C segment vary significantly from period to period.

Infrastructure

Traffic and Fees for Toll Roads

The majority of our toll roads revenues derive from the Norvial concession. Unlike our other toll road concessions, our revenues from the Norvial concession depend on traffic volume. Traffic volume on the Norvial road increased 10.6% from 2010 to 2011, 7.4% from 2011 to 2012 and 4.3% from the first quarter of 2012 to the first quarter of 2013 (based on vehicle equivalents, as defined in “Business—Infrastructure—Principal Infrastructure Activities—Toll Roads—Norvial”) and such increases are largely driven by economic activity levels in Peru. For the Norvial toll road, the toll rate is set out in the Norvial concession agreement and adjusted in accordance with a contractual formula that takes into account the nuevo sol/U.S. dollar exchange rate and Peruvian and United States inflation. Under our Survial and Canchaque road concessions, our revenues consist of annual fees paid by the Peruvian Ministry of Transport and Communications in consideration for the operation and maintenance of the roads, which can vary depending on the amount of road maintenance required due to road wear and tear.

62

Under the Norvial concession, we are required to expand certain stretches of the highway, by, among other things, adding two additional lanes. The first stage of construction was completed in 2008 and the second stage is expected to begin between 2014 and 2015. We estimate that Norvial’s capital investment for the second stage will be approximately US$100 million.

Mass Transit

We generate revenue from our Lima Metro concession based on kilometers travelled per train, with the fee per kilometer, the number of trains required to be in operation and the number of kilometers that we are required to travel established by the terms of the concession. Our revenues do not depend on passenger traffic volume. Our results in this concession are directly influenced by the timely acquisition, set up, reliability and proper operation of our trains as well as by the timing of the government’s completion of the 12.1 kilometer second stretch of Line One (which is being constructed by a joint operation in which our E&C segment participates). In the second half of 2011, we incurred expenses during the pre-operation phase of the Lima Metro, a period during which we did not generate revenues. In 2012, we generated losses as a result of the limited number of trains (five) we initially operated. However, we expected losses during the first year of operation of the Lima Metro and, as required by the concession, we have ordered 19 new trains and expect to generate profits once additional trains are in operation. We are scheduled to receive the new trains on a periodic basis and expect to have all trains (24) in operation by the third quarter of 2014. As of the date of this prospectus, we have received eleven additional trains, however, we are currently awaiting approval from the Ministry of Transport and Communications to begin putting these trains in operation. In addition, according to the government, the second stretch of Line One of the Lima Metro is expected to be completed by the third quarter of 2014.

We estimate that GyM Ferrovías will make a total of S/.830 million (US$320.6 million) in capital expenditures in connection with the Lima Metro. As of March 31, 2013, GyM Ferrovías had spent S/.410.8 million (US$158.7 million) of this amount. We expect to finance the additional capital expenditures required for the Lima Metro with a combination of cash from operations and the incurrence of indebtedness.

Energy

A significant part of the revenues in our Infrastructure segment depends on global prices for oil. Under our hydrocarbon extraction service contracts, we are entitled to a variable fee, which is based on the level of production of each field and a basket of international crude oil prices. Historically, oil prices have been volatile and are likely to be volatile again in the future. During 2010, 2011 and 2012, average Brent crude prices were approximately US$79.51, US$111.26 and US$111.65 per barrel and the average fee we received in these years was US$61.08, US$84.00 and US$86.13 per barrel of extracted oil, respectively. During the first quarters of 2012 and 2013, average Brent crude prices were approximately US$118.50 and US$112.50 per barrel, respectively, and the average fees we received during the first quarters of 2012 and 2013 were US$ 90.54 and US$87.19 per barrel of extracted oil, respectively. Because our activities are conducted in mature oil fields, which have been producing oil for over 100 years in the case of Block I and over 50 years in the case of Block V, our oil production depends primarily on the level of our capital expenditures undertaken for drilling and production purposes.

Our gas processing plant has a long-term delivery and gas processing and fractionation contract with Empresa Eléctrica de Piura S.A. (“EEPSA”), a thermal power generation subsidiary of the Endesa group. Under the contract, EEPSA delivers wet natural gas that it purchases from onshore and offshore gas operators in the area. We are responsible for all operating costs of the gas processing plant but are entitled to keep revenues from the sale of all resulting natural gas liquids to third parties after delivery of all dry gas and payment of a variable royalty to EEPSA. Volumes processed by our gas processing plant depend upon gas volumes demanded by EEPSA for its gas-fired turbines, which can vary significantly. Prices for natural gas liquids can also fluctuate significantly and are affected by market prices for crude oil.

63

In connection with our fuel storage terminal business, under a contract with Petroperú, we receive revenues related to monthly reserved volume in storage tanks for refined crude products (storage fee) and for volumes loaded and delivered into railroad cars or cistern trucks to each terminal (throughput fee). These fees are adjusted annually to account for U.S. inflation. Our fuel storage activities are carried out under a 15-year contract, which expires in August 2014. Consequently, the results of operations of our Infrastructure segment will be adversely affected if this contract is not extended or renewed.

The results of operations of our Infrastructure segment are affected by our ability to win new concessions and government contracts, which depend in part on government policies and our ability to compete effectively. We currently have five concessions as well as long-term government contracts in this segment. Joint operations in which we participate have been awarded concessions, and are currently negotiating contracts for, the expansion of two major highways within the city of Lima. If we are able to enter into satisfactory contracts, we believe these concessions will significantly increase the results of operations of our Infrastructure segment. However, we cannot assure you that we will be able to negotiate these contracts on favorable terms or at all. In addition, our government contract to operate nine fuel storage terminals is scheduled to expire in August 2014, and we cannot assure you that it will be extended or renewed on favorable terms or at all.

Our results in our Infrastructure segment are also affected by the timing of the commencement of operations under our concessions, as well as when we are required to undertake significant capital investments or major construction works under the terms of our concessions. Under our Norvial and Lima Metro concessions, we are required to undertake capital investments during the initial years of the concessions for which we are compensated throughout the term of the concessions by our toll rate in the case of the Norvial concession and tariffs in the case of the Lima Metro concession. Under our Survial, Canchaque and La Chira concessions, we generate revenues in our Infrastructure segment from our construction activities during the pre-operational phase, and once operations commence we generate revenues from fees related to operation and maintenance. Survial, Canchaque and La Chira have financed their construction costs through the sale of government certificates of construction to financial institutions at a discount from face value. Certificates of construction are negotiable instruments that the Peruvian government typically delivers upon completion of each stage of a project and which entitle the holder to receive payment from the government equal to the capital investment made in the corresponding stage upon completion of the entire project. Accordingly, the results of our Infrastructure segment may be affected by the discount rates obtained on the sale of government certificates of construction. For more information on our obligations and compensation under our concessions, see “Business—Infrastructure.”

Real Estate

The results of operations of our Real Estate segment are driven by the number of units we develop and deliver in a reporting period, our mix of unit sales (affordable housing versus housing), unit prices, land purchase prices and our costs of construction. These results are also affected by a number of factors that may impact the Peruvian real estate sector as a whole, including: the availability of government subsidies for affordable housing; prices of suitable land in particular areas; regulation of real estate development imposed by national, regional and local laws and regulators, and the time required to obtain applicable construction permits and licenses; the unemployment rate and wage levels; prevailing interest rates and availability of financing; the supply in the market; the level of customer interest in our new projects; and our costs, such as the price of labor, materials, insurance, taxes and other public charges. We delivered 2,142, 1,244, 1,368 and 304 units in 2010, 2011, 2012 and the first quarter of 2013, respectively.

The results of operations of our Real Estate segment are also significantly affected by our sales of land parcels. Due to the appreciation of land prices in Peru, and because we record our land holdings at book value (i.e., without marking to market), our recent land sales have resulted in high margins.

64

In addition, the net profit attributable to controlling interests of our Real Estate segment is significantly affected by the financing and commercial arrangements we use to purchase land and to develop real estate projects. Depending on the level of non-controlling interests used to finance our real estate projects, our Real Estate segment tends to have significant net profit attributable to non-controlling interests. See “—Results of Operations—General—Real Estate.”

Technical Services

The results of operations of our Technical Services segment, especially our activities relating to IT and electricity networks services, are affected by the economic growth of the countries in which we operate. As companies expand in response to economic growth, they tend to outsource certain activities in order to focus on their core businesses.

Our results in the operation and maintenance of infrastructure assets depend on our ability to obtain contracts from the government or infrastructure concessionaires, such as those in our Infrastructure segment, which depend on government policies and our ability to compete effectively. We obtained three public-sector road contracts at the end of 2010 as well as three new public-sector road contracts at the end of 2012; however, two public sector road contracts expired in December 2012 and were not renewed until May and June, respectively, of 2013, and, as a result, impacted our results of operations during the first quarter of 2013. We typically obtain higher revenues from these contracts during the commencement of services as we bring the road to proper operating condition, and lower revenues at the end of the contract term as services wind down.

The results of operations of our Electricity Networks Services are affected by our ongoing restructuring of the business after our acquisition of a controlling interest in CAM in February 2011.

Critical Accounting Estimates and Judgments

Estimates and judgments used in connection with the preparation of our financial statements are continuously evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

Critical Accounting Estimates and Assumptions

We make estimates and assumptions concerning our future economic performance. These estimates and assumptions are required to be made because the information used in the presentation of the financial information is currently not available, is dependent on future events, or cannot be calculated with a high degree of accuracy. The resulting accounting estimates will, by definition, seldom equal the related actual results. If outcomes in the next fiscal year are much different than current assumptions, a material adjustment might be required to the carrying amount of the assets and liabilities. However, our management considers that the estimates and assumptions used in connection with the preparation of our consolidated financial statements included in this prospectus do not have a significant risk of causing a material adjustment to the balances of assets and liabilities in subsequent years.

Percentage-of-Completion Revenue Recognition

Revenue from construction contracts is recognized under the percentage-of-completion method which requires the final margin from construction contracts to be estimated. Projections of these margins are performed by our management based on work execution budgets and adjusted periodically based on updated information reflecting the actual performance of work. The estimated contract revenue and total cost estimates are reviewed often as work advances and change orders are initiated and approved. In this regard, our management considers that the estimates made as of March 31, 2013 are reasonable. When change orders are presented and work is commenced pursuant to those change orders before the terms of the orders are formally agreed with the client, revenue is recognized equal to costs incurred (no profit component is recognized) until the additional work is completed and the change orders are formally approved.

65

Contract revenue is recognized as revenue in the income statement in the accounting periods in which the work is performed. Contract costs are recognized as cost of sales in the income statement in the accounting period in which the work to which they relate is performed. However, any expected and probable excess of total contract costs over total contract revenue for the relevant contract is recognized as an expense immediately. Furthermore, any changes in contract estimates are recognized as a change in accounting estimates and recognized in the period the change is made and in future periods if applicable. In certain construction contracts, the terms of these agreements allow for an amount to be withheld by the clients until construction has been completed. Under these contracts the full amount may not be received until the next quarter of the year. As of December 31, 2010, 2011 and 2012, a sensitivity analysis was performed considering a 10% increase or decrease in our gross margin (i.e., gross profit as a percentage of revenues). As of December 31, 2012, a 10% positive or negative change in our gross margin would result in a S/.37.2 million increase or decrease, respectively, in our profit before taxes.

Goodwill Impairment Reviews

Goodwill arises from the acquisition of subsidiaries and represents the excess of the cost of acquisition over the fair value of the acquiree’s net identifiable assets at the acquisition date. At March, 31, 2013 we had no goodwill impairment.

Impairment reviews are undertaken annually, or more frequently if there is a triggering event, to determine if goodwill arising from business acquisitions has suffered any impairment. For this purpose, goodwill is attributed to the different cash-generating units to which it relates. The recoverable amount of the cash-generating units has been determined based on its value-in-use calculations.

This evaluation requires the exercise of our management’s professional judgment to analyze any potential indicators of impairment as well as the use of estimates in determining the value-in-use, including the preparation of future cash flows, macro-economic forecasts as well as defining the interest rate at which said cash flows will be discounted.

If we experience a significant drop in revenues or a drastic increase in costs or changes in other factors, the fair value of business units might decrease. If our management determines the decrease is permanent we might have to write down our goodwill which would be recognized in earnings.

As of March 31, 2013, based on the impairment testing performed by our management, no goodwill impairment losses were required to be recognized because the recoverable amount of the cash-generating units subject to testing was substantially higher than their related carrying amounts. We have not had any impairment to goodwill over the last three years.

The most significant assumptions are gross margin, growth rate and the discount rate which are included in note 15 of our audited annual consolidated financial statements included in this prospectus.

We have performed a sensitivity analysis on the gross margin and discount rate which is included below:

a. Gross margin: Our fair value is significantly higher than book value. If the gross margin were adjusted down by 10%, the fair value would be 144% higher than the book value; conversely, if the gross margin were adjusted up by 10%, the fair value would be 151% higher than the book value.

b. Discount rate: Our fair value is significantly above our book value. If the discount rate were adjusted down by 10%, the fair value would be 136% higher than the book value; conversely if the discount rate were adjusted up by 10%, the fair value would be 93% higher than the book value.

66

Taxes

Determination of the tax obligations and expenses requires interpretations of the applicable tax laws and regulations. We seek legal tax counsel’s advice before making decisions on tax matters. Although our management considers its estimates to be prudent and appropriate, differences of interpretation may arise with the Peruvian tax authorities which may require future tax adjustments.

Deferred tax assets and liabilities are calculated by taking the temporary differences of the tax basis of assets and liabilities and the financial statement basis using the tax rates in effect for each of the years in which the differences are expected to reverse. Any change in tax rates will affect the deferred tax assets and liabilities. This change will be recognized in income in the period the change takes effect.

Our management makes estimates for our deferred income tax valuation allowance. This allowance may be increased or decreased if we determine it to be more likely than not that our valuation allowance needs to be adjusted. If a tax position is not more likely than not to ultimately be realized, no tax benefit is recorded.

We base estimates for the valuation allowance on all available evidence which includes historical data, projected income, current operations and tax planning strategies. The deferred tax asset is supported by the assumption that we will continue to generate income in the future. If our management determines that in the future revenues will not be sufficient to cover the deferred tax asset, we would adjust the valuation account for deferred tax income.

Provision for Well Closure Costs

We estimate the present value of our future obligation for well closure costs and increase the carrying amount of the asset that will be withdrawn in the future and that is reflected under “intangibles” in our balance sheet. The discount rate used for the present value calculation was 1.78%, based on the 10-year bond rate as of December 31, 2012. As of March 31, 2013, the present value of the estimated provision for closure activities for the 85 wells amounted to S/.4.9 million. Subsequently, this liability is attributed to profit or loss during the useful life of the assets that gave rise to it. The well closure liability is adjusted to reflect the changes that resulted from the passage of time and from revisions of either the date of occurrence or the amount of the present value of the obligations originally estimated. With a discount rate of 1.78%, intangibles in our balance sheet were S/.4,896,747. If the discount rate was adjusted down by 10%, the intangibles in our balance sheet would be S/.4,945,264; conversely if the discount rate was adjusted up by 10%, the intangibles in our balance sheet would be S/.4,848,900.

During 2012, we recorded an additional S/.4.9 million, charged to the intangible asset account, credited to the well closure liability. This is to reflect estimated obligations to close 70 productive wells included in the service agreements for Blocks I and V. This provision is increased monthly, charged to results, on an incremental value basis.

Critical Judgments in Applying Accounting Policies

CAM Acquisition

Under IFRS 3, an entity recognizes a profit on an acquisition when the fair value of the assets acquired, net of the liabilities assumed exceeds the consideration paid. This accounting standard presumes that recognition of a profit on a business acquisition is unusual; therefore, it requires the buyer to review the determination of the fair values of the acquired assets, liabilities and price paid before recognizing any gains. Furthermore, IFRS 3 authorizes a review period of 12 months from the acquisition date for an entity to adjust the determination of the fair values of the acquired assets and liabilities and, accordingly, adjust the goodwill or gain generated from the acquisition, as applicable.

67

On February 24, 2011, we acquired a controlling interest in CAM and, as a result of the process of allocating the purchase price paid, the fair value of the assets acquired, net of the liabilities assumed, was determined to have exceeded the consideration paid by S/.45.2 million. At the date of issue of our consolidated financial statements for the year ended December 31, 2012, the 12-month period requirement for fair value review had been met and our management considers that it has reasonably reviewed the values attributable to the assets and liabilities of the business acquired; accordingly, it has completed the process of allocating the consideration paid, and has therefore, recognized the above-mentioned profit on acquisition in the year-end profit or loss.

Estimated Useful Life of Machinery and Equipment

We review on an annual basis the useful lives of our machinery and equipment. The evaluation of the useful lives is made based on the hours of use and is performed by our applicable technical internal area. This estimation of work hours is performed based on historical data considering the estimated productive capacity of the asset and is expressed in a rate per unit of production or hour. Our management determined not to change the useful life during 2012 because, based on its own assessments, the useful lives already reflected the current economic conditions of our operating environment.

New Accounting Pronouncements

The following standards, which have been issued but were not yet effective during 2012, are relevant to our activities:

• IFRS 7, “Financial Instruments: Disclosures” as amended in October 2010 modifies the disclosures required so that the users of the financial statements may assess the risk exposure related to financial asset transfers and the effect of this risk on the entity’s financial position. For us, this amendment came into effect on January 1, 2013.

• IFRS 9, “Financial Instruments,” addresses the classification, measurement and recognition of financial assets and financial liabilities. It replaces the parts of International Accounting Standard (“IAS”) 39 that relate to the classification and measurement of financial instruments. IFRS 9 requires financial assets to be classified into two measurement categories: those measured at fair value and those measured at amortized cost. The classification depends on the entity’s business model for managing its financial instruments and the contractual cash flow characteristics of the instrument. For financial liabilities, the standard retains most of the IAS 39 requirements. Application of IFRS 9 will be mandatory from January 1, 2015.

• IFRS 10, “Consolidated Financial Statements,” replaces IAS 27 and Standing Interpretations Committee (“SIC) 12 and builds on existing principles by identifying the concept of control as the determining factor in whether an entity should be included within the consolidated financial statements of the parent company. The standard provides additional guidance to assist in the determination of control where this is difficult to assess. IFRS 10 came into effect on January 1, 2013.

• IFRS 11, “Joint Arrangements,” which replaces IAS 31, amends the classification of joint arrangements in only two categories (joint operations and joint ventures), depending on whether the investors have contractual rights and obligations on the assets and liabilities of the arrangement (joint operation) or whether investors have a residual right on the equity of the arrangement (joint venture). This standard discontinues the application of proportional consolidation method. IFRS 11 came into effect on January 1, 2013.

• IFRS 12, “Disclosures of Interests in Other Entities” includes the disclosure requirements for all forms of interests in other entities, including joint arrangements, associates, special purpose vehicles and other off-balance sheet vehicles. IFRS 12 came into effect on January 1, 2013.

• IFRS 13, “Fair Value Measurement,” aims to improve consistency and reduce complexity by providing a precise definition of fair value and a single source of fair value measurement and disclosure

68

requirements for use across IFRS. The requirements do not extend the use of fair value accounting but provide guidance on how it should be applied where its use is already required or permitted by other standards within IFRS. IFRS 13 came into effect on January 1, 2013.

• Amendment to IAS 1, “Presentation of Financial Statements” relating to other comprehensive income requires for entities to group the items of “other comprehensive income” depending on whether they are reclassificable or not to the statement of comprehensive income. These amendments do not specify which items should be included in “other comprehensive income.” For us, this standard came into effect on January 1, 2013.

• IAS 19, “Employee Benefits” was amended in June 2011 by the IASB. The amendments eliminate the corridor approach and recognize financial expenses on a net basis. This amendment came into effect on January 1, 2013.

• IAS 27, “Separate Financial Statements” was amended in May 2011 by the IASB. The new standard includes the alignment of the separate financial statements which remain effective once the provisions of control were included in Normas Internacionales de Información Financiera (NIIF) 10. For us, this standard came into effect on January 1, 2013.

• IAS 28, “Investments in Associates and Joint Ventures” was amended in May 2011 by the IASB. The new standard includes guidelines to recognize joint ventures and associates under the equity method of accounting. This standard became effective for us on January 1, 2013.

We have carried out an initial assessment of the impact of these new standards on our financial position and results. The adoption of IFRS 11 required a more detailed analysis of the effect, given our participation in several arrangements with third parties. However, after such initial assessment, management considers that the standard will not have a material impact on our financial position or performance because our arrangements qualify as joint operations under IFRS 11. The accounting to be applied to our joint operations under IFRS 11 is similar to the accounting previously applied to these arrangements under IAS 31. We recognize, in relation to our interest in a joint operations, our assets and liabilities, including our share of any assets or liability held jointly with our partners as well as our share of revenues and expenses from the joint operations. The other standards described above only affect certain disclosures in our consolidated financial statements. There are no other IFRS or the International Financial Reporting Interpretations Committee (IFRIC) interpretations that are not yet effective that would be expected to have a significant impact on our consolidated financial statements.

Internal Controls and Procedures

We are not currently required to comply with Section 404 of the U.S. Sarbanes-Oxley Act of 2012 and, therefore, we have not made a formal assessment of the effectiveness of our internal control over financial reporting for that purpose. We and our independent registered public accounting firm have identified a material weakness in our internal control over financial reporting as a result of certain errors we found in our consolidated statement of cash flow for 2012. In order to present investors in this offering with our corrected cash flow statement, we have restated our audited annual consolidated financial statements included in this prospectus. For a description of the changes we made to our consolidated statement of cash flow, see note 32 to our audited annual consolidated financial statements included in this prospectus.

These errors did not have any effect on the net increase (decrease) in cash for the year ended December 31, 2012. Furthermore, all underlying transactions were properly recorded in the statement of financial position, income statement, statement of comprehensive income and statement of changes in shareholders’ equity, which did not need to be revised or restated.

A “material weakness” is a deficiency, or combination of deficiencies, in internal controls such that there is a reasonable possibility that a material misstatement in financial statements will not be prevented or timely detected. The material weaknesses in our internal control over financial reporting that we identified related to the

69

insufficient training and experience of certain of our accounting personnel with respect to the application of IFRS. We are not aware of any other material weakness in our internal control over financial reporting.

The measures that we intend to implement to address the identified material weakness include: (i) enhancing the IFRS knowledge base of our accounting personnel through increased internal and external training; (ii) hiring additional personnel experienced in IFRS; and (iii) completing the implementation of Hyperion, an automated consolidation system, which we began in November 2012 and expect to complete by July 2013. We will be required under the U.S. Securities Exchange Act of 1934 to maintain disclosure controls and procedures and internal control over financial reporting. Section 404 of the U.S. Sarbanes-Oxley Act of 2002 will require us, for our fiscal year ending December 31, 2014 and subsequent years, to document and test the effectiveness of our internal control over financial reporting in accordance with an established internal control framework and to report on our conclusion as to the effectiveness of our internal controls. It will also require an independent registered public accounting firm to test our internal control over financial reporting and to report on and attest to the effectiveness of such controls. See “Risk Factors—Risks Relating to the Offering and our ADSs—If we are unable to implement and maintain effective internal control over financial reporting in the future, or if we fail to promptly remediate our current material weakness, our results of operations and the price of our ADSs could be adversely affected.”

Results of Operations

General

Accounting for Subsidiaries, Joint Operations and Associated Companies

Results of our subsidiaries, joint operations and associated companies are reflected in our financial results. We refer to our subsidiaries as those entities over which we exercise control. We consolidate the results of our subsidiaries in our financial statements and we reflect the profit corresponding to the minority interests in our subsidiaries under “profit attributable to non-controlling interests” in our income statement. We refer to business activities in which we share control with unrelated entities as joint operations. Our joint operations are conducted through an agreement with a third party to carry out specific projects. We contribute our assets to these projects and derive revenue from their use. In our financial statements we recognize, in relation to our interest in a joint operation, our assets and liabilities, including our share of any asset or liability we hold jointly with our partner, as well as our share of revenue and expense from the joint operation. We refer to our associated companies as those entities over which we have significant influence but do not control. We reflect the results of our associated companies under the equity method of accounting in our financial statements under the line item “share of the profit and loss in associates” in our income statement. For further information, see note 2.2 to our audited annual consolidated financial statements included in this prospectus.

On March 1, 2012, as a result of our acquisition of control of Stracon GyM, we began to consolidate Stracon GyM’s results and reflect net profit attributable to the non-controlling interests with respect to the other owner of the company in our income statement. Prior to that date, the business operated by Stracon GyM was a joint operation, and, accordingly, we accounted for our share of revenue and expenses from Stracon GyM along with our assets and liabilities, including our share of any of the assets we held jointly, in our financial statements and did not reflect any non-controlling interests. For further information, see notes 25 and 28(b) to our audited annual consolidated financial statements included in this prospectus.

Intersegment Transactions

Some of our segments from time to time provide services to our other segments. In 2012, we obtained 2.2% of the revenues in our E&C segment from the engineering design of La Chira waste water treatment plant for our Infrastructure segment and the construction of real estate for our Real Estate segment; 35.4% of the revenues in our operation and maintenance of infrastructure assets line of business derived from services provided to Norvial, Survial, Canchaque and the Lima Metro; and 2.7% of the revenues in our IT services line of business derived

70

from IT and outsourcing services provided to several of our other lines of businesses. In the first quarter of 2013, we obtained 2.9% of the revenues in our E&C segment from the engineering design and construction of La Chira waste water treatment plant for our Infrastructure segment and the construction of office buildings for our Real Estate segment and office buildings for corporate use, 27.5% of the revenues in our operation and maintenance of infrastructure assets line of business derived from services provided to Norvial, Survial, Canchaque and the Lima Metro, and 2.4% of the revenues of our IT services line of business derived from IT and outsourcing services provided to several of our lines of business. Accordingly, in such circumstances, the segment providing services recognizes revenues and the segment receiving such services recognizes costs of sales relating to the services provided. For example, in the case of La Chira, in which our E&C segment provides services to our Infrastructure segment, our E&C segment recognizes revenues and our Infrastructure segment recognizes costs of sales with respect to the fees charged by our E&C segment for those services. In consolidation, these intersegment revenues and cost of sales are eliminated in our financial results. Nonetheless, our Infrastructure segment, in particular, may recognize gross profits or losses based on the difference between the fees the segment charges in accordance with concession terms and costs it incurs relating to services provided by our other segments. For more information on our segments, see note 5 to our audited annual consolidated financial statements and note 7 to our unaudited interim consolidated financial statements included in this prospectus.

Engineering and Construction

We obtain revenues in our E&C segment from the engineering and construction services we provide to our clients, which we recognize under the percentage-of-completion method of accounting. For further information, see note 2.25 to our audited annual consolidated financial statements included in this prospectus. We receive unrestricted client advances in a substantial majority of our E&C projects, on average equal to approximately 13% of the contract price, which we record as an account payable. We typically invoice our clients on a periodic basis as each project progresses, deducting from the related advances on a proportional basis. For further information, see note 18 to our audited annual consolidated financial statements included in this prospectus. Our cost of sales in our E&C segment includes labor, subcontractor expenses, materials, equipment, and project-specific general expenses.

Infrastructure

In our Infrastructure segment, we recognize revenues and cost of sales as follows:

(1) Toll Roads:

• For Norvial, we obtain revenues for toll fees collected, minus deductions required to be transferred to the government as described in “Business—Infrastructure—Principal Infrastructure Activities—Toll Roads—Norvial,” which we recognize upon receipt. Cost of sales for Norvial include fees paid to third parties (primarily our subsidiary Concar) for operation and maintenance services as well as the amortization of the road concession registered as an intangible asset in our financial statements; and

• For Survial and Canchaque, we obtain revenues for routine and periodic maintenance services, which we recognize in the period in which the services are performed. Cost of sales for Survial and Canchaque include fees paid to third parties (primarily our subsidiary Concar) for operation and maintenance services. We do not recognize the Survial and Canchaque concessions as intangible assets and therefore do not amortize the concessions.

For further information, see notes 2.15(c) and 15 to our audited annual consolidated financial statements included in this prospectus.

(2) Mass Transit: We obtain revenues from our Lima Metro concession based on a tariff per kilometer traveled by our trains in operation in accordance with a schedule established in our concession agreement, which we recognize in the period in which the services are performed. Under the concession, the tariff is comprised of three components: (i) fees related to our operation and maintenance services; (ii) fees related to the Peruvian

71

government’s repayment of the amounts we invest to purchase trains and other infrastructure for the Peruvian government; and (iii) fees related to interest we charge the Peruvian government in connection with the amounts we invest to purchase such trains and other infrastructure. In 2012, the fees related to items (i), (ii) and (iii) were S/.58.9 million, S/.0.0 million and S/.11.6 million, respectively; and in the first quarter of 2013, the fees related to items (i), (ii) and (iii) were S/.14.9 million, S/.0.0 million and S/.5.7million, respectively. We only recognize in our income statement the portion of the tariff that relates to items (i) and (iii). We record the amounts paid by us that relate to item (ii) as long-term accounts receivables from the Peruvian government. Accordingly, tariff payments received relating to item (ii) reduce our accounts receivables but do not impact our income statement or EBITDA, and we do not amortize our investments in our income statement as our investment in the concession is recorded as an account receivable with the government rather than a depreciable investment. For further information, see note 8 to our audited annual consolidated financial statements included in this prospectus. Cost of sales for the Lima Metro include fees paid to third parties (primarily our E&C segment, our subsidiary Concar and other subcontractors) for construction and operation and maintenance services, energy, and our financing costs related to the purchase of trains.

(3) Water Treatment: Beginning in March 2012, we obtained revenues from the engineering design and construction of La Chira waste water treatment plant, which we recognize based on the percentage-of-completion method of accounting. Once the plant begins operations, which is expected to occur at the beginning of 2015, we will obtain revenues only for operation and maintenance services, which we will recognize in the period in which the services are performed. During the construction phase, cost of sales for La Chira includes fees paid to third parties, primarily our E&C segment, for engineering and construction services. During the operation phase, cost of sales for La Chira will include personnel charges and maintenance of infrastructure.

(4) Energy: We obtain revenues from extraction services related to oil and gas production, fuel storage services, and the sale of natural gas liquids derived from our gas processing and fractionation services, which we recognize in the period in which the services are performed and, in the case of sale of natural gas liquids, when the sale is made. Cost of sales for our energy line of business includes labor, materials, amortization of oil wells, depreciation of the gas plant, maintenance and general expenses.

Real Estate

We obtain revenues in our Real Estate segment from sales of affordable housing and housing units, commercial buildings and land parcels, which we recognize at the time of delivery of the unit or building and, in the case of land parcels, at the time of the sale. We typically pre-sell our affordable housing and housing units prior to and during construction, and use the related proceeds we receive to finance the construction of the units. These pre-sale funds are restricted and released from escrow to us periodically as construction progresses. Our Real Estate cost of sales includes the cost to purchase land, costs of architectural design and construction (which usually includes payments to third parties, primarily our E&C segment), licensing and permit costs, personnel costs, and fees to third parties related to sanitation or electrical engineering. In 2012 and the first quarter of 2013, our cost of land that is allocated to units delivered during these periods amounted to S/.23.8 million and S/.3.9 million, respectively. We recognize land purchases as inventory, and, accordingly, do not mark-to-market the value of our land for changes in fair value. For further information, see note 12 to our audited annual consolidated financial statements included in this prospectus.

In our Real Estate segment, we have significant net profit attributable to non-controlling interests. We hold a significant portion of our land bank through Almonte in which we have a 50.4% interest, and we consolidate Almonte’s results in our financial statements. In addition, we undertake a significant number of our real estate projects through entities in which we may have a majority interest, co-equal interest or minority interest; when we have control over these entities, we consolidate their results in our financial statements regardless of whether we own a majority of the capital. Furthermore, in connection with our affordable housing projects, we generally partner with real estate investment funds and insurance companies that provide between 60% and 70% of the total capital required to purchase the land and cover certain pre-construction costs in exchange for equity in the

72

project. Although we typically own a minority interest in these projects, we consolidate their results in our financial statements because we exercise control over the project. Accordingly, we reflect the profit corresponding to our real estate partners under net profit attributable to non-controlling interests in our income statement. See “—Accounting for Subsidiaries, Joint Operations and Associated Companies.”

Technical Services

In our Technical Services segment, we recognize revenues and cost of sales as follows:

(1) Operation and Maintenance of Infrastructure Assets: We obtain revenues from our operation and maintenance of infrastructure assets line of business for the operation and maintenance services we provide to the government and concessionaires (currently concessions within our Infrastructure segment), which we recognize in the period in which the services are performed. We receive unrestricted advances with respect to our service contracts with the government, that vary from approximately 10% to 30% of the contract price, which we record as an account payable. We typically invoice our clients on a periodic basis as the project progresses, deducting from the related advances on a proportional basis.

Revenues

Our total revenues increased by 15.2%, or S/.167.7 million, from S/.1,100.4 million for the first quarter of 2012 to S/.1,268.1 million for the first quarter of 2013. This increase was due mainly to growth in our E&C segment, primarily due to an increase in contract mining and civil works activities and, to a lesser extent, to the revenues of Vial y Vives, in which we acquired a controlling interest in October 2012, as well as growth in our Real Estate segment, primarily due to an increase in units delivered.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between the end of 2012 and the first quarter of 2013 resulted in an increase in our consolidated revenues, as expressed in nuevos soles, of approximately S/.9.4 million, or 0.7%, during the first quarter of 2013, as the nuevo sol depreciated against the U.S. dollar by approximately 0.9% and against the Chilean peso by approximately 2.2%.

The following table sets forth a breakdown of our revenues by segment for the first quarters of 2012 and 2013.

Cost of Sales

Our total cost of sales increased by 12.9%, or S/.122.2 million, from S/.946.1 million for the first quarter of 2012 to S/.1,068.3 million for the first quarter of 2013. This increase was related to the growth in our revenues.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between the end of 2012 and the first quarter of 2013 resulted in an increase in our consolidated cost of sales, as expressed in nuevos soles, of approximately S/.4.1 million, or 0.4%, during the first quarter of 2013.

Gross Profit

Our gross profit increased by 29.5%, or S/.45.5 million, from S/.154.3 million for the first quarter of 2012 to S/.199.8 million for the first quarter of 2013. Our gross margin for the first quarter of 2013 was 15.8% compared to 14.0% for the first quarter of 2012. This increase in our gross margin was mainly due to higher gross margins in our Real Estate segment, primarily as a result of higher prices at one of our affordable housing developments, as well as in the E&C segment, primarily due to higher margins in contract mining activities as a result of the stage of execution of certain projects.

Administrative Expenses

Our administrative expenses increased by 22.1%, or S/.13.8 million, from S/.62.4 million for the first quarter of 2012 to S/.76.2 million for the first quarter of 2013, primarily due to the consolidation of Vial y Vives, in which we acquired a controlling interest in October 2012 and which increased our administrative expenses by S/.5.5 million; the increase of administrative expenses in the E&C segment in line with the growth in revenues in this segment; and, to a lesser extent, an increase in administrative expenses in our Technical Services segment as a result of the preparation of concession bids. As a percentage of revenues, our administrative expenses grew to 6.0% in the first quarter of 2013 from 5.7% in the first quarter of 2012.

Other Income (Expenses)

Our other income (expenses) decreased S/.4.2 million, from S/.12.7 million for the first quarter of 2012 to S/.8.5 million for the first quarter of 2013. This decrease was primarily due to a lower reversal of provisions in connection with the CAM acquisition from S/.11.9 million in the first quarter of 2012 to S/.3.9 million in the first quarter of 2013, partially offset by an extraordinary gain of S/.2.3 million in our E&C segment from compensation received in connection with a government claim related to a project completed in 2011, as well as a reversal of provisions in connection with the Vial y Vives acquisition in the amount of S/.4.6 million. For further information, see “—Factors Affecting Our Results of Operations—Acquisitions.”

Operating Profit

Our operating profit increased 25.2% or S/.26.5 million, from S/.105.2 million for the first quarter of 2012 to S/.131.7 million for the first quarter of 2013. Our operating margin (i.e., operating profit as a percentage of revenues) was 10.4% for the first quarter of 2013 compared to 9.6% for the first quarter of 2012. Despite the increase in administrative expenses in our E&C and Technical Services segments and lower other income (expenses), our operating profit increased in the first quarter of 2013 due to higher gross profit, mainly in our E&C and Real Estate segments.

Business Segments

The following discussion analyzes our key results of operations on a segment basis. For further information on our business segments, see note 7 to our unaudited interim consolidated financial statements included in this prospectus.

Engineering and Construction

The table below sets forth selected financial information related to our E&C segment.

	Three months ended March 31,
	2012		2013		Variation
	(unaudited)
	(in millions of S/.)				%
Revenues		717.9		889.2		23.9
Gross profit		84.1		121.2		44.1
Operating profit		50.5		78.6		55.6

Revenues. Our E&C revenues increased 23.9%, or S/.171.3 million, from S/.717.9 million for the first quarter of 2012 to S/.889.2 million for the first quarter of 2013, primarily due to the growth in revenues in our contract mining and civil works activities and, to a lesser extent, the S/.21.3 million in revenues from Vial y Vives in the first quarter of 2013, a company in which we acquired a controlling interest in October 2012. Excluding revenues from Vial y Vives, our E&C revenues increased 20.9% in the first quarter of 2013 as compared to the first quarter of 2012.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between the end of 2012 and the first quarter of 2013 resulted in an increase in our E&C revenues, as expressed in nuevos soles, of approximately S/.5.9 million, or 0.7%, during the first quarter of 2013.

The following describes variations in our E&C revenues by business activities, types of contracts and end-markets:

E&C Activities: For the first quarter of 2013, approximately 4.9%, 21.0%, 28.1%, 25.7% and 20.2% of our E&C revenues were derived from engineering services, electromechanic construction, civil construction, contract mining and building construction activities, respectively. For the first quarter of 2012, approximately 5.3%, 23.8%, 27.2%, 20.3% and 23.4% of our E&C revenues were derived from engineering construction, electromechanic construction, civil construction, contract mining and building construction activities, respectively. Despite variations in the proportional weight of our various E&C activities, the

76

revenues derived from each of our E&C activities increased in absolute terms during the first quarter of 2013, with contract mining increasing significantly due to an increase in project awards. For a description of our E&C business activities, see “Business—Engineering and Construction—Principal Engineering and Construction Activities”;

E&C Contracts: For the first quarter of 2013, approximately 46.5%, 38.0%, 5.2% and 10.4% of our E&C revenues were derived from cost-plus fee, unit price, lump-sum and EPC contracts, respectively. For the first quarter of 2012, approximately 34.6%, 53.9%, 5.2% and 6.3% of our E&C revenues were derived from cost-plus fee, unit price, lump-sum and EPC contracts, respectively. During the first quarter of 2013 we continued to derive significant revenues from cost-plus fee and unit price contracts, with a significant increase in cost-plus fee contracts. For a description of our contractual arrangements, see “Business—Engineering and Construction—Contracts” and “—Factors Affecting Our Results of Operations—Engineering and Construction”; and

E&C End-Markets: For the first quarter of 2013, approximately 40.9%, 20.4%, 10.0%, 12.4%, 11.1%, 4.6% and 0.5%, of our E&C revenues were derived from mining, real estate buildings, power, oil and gas, transportation, water and sewage, and other end-markets, respectively. For the first quarter of 2012, approximately 43.4%, 23.3%, 16.1%, 7.7%, 5.6%, 3.2% and 0.8%, of our E&C revenues were derived from mining, real estate buildings, power, oil and gas, transportation, water and sewage, and other end-markets, respectively. During the first quarter of 2013 we continued to derive significant revenues from the mining end-market, and we experienced growth in revenues particularly from the transportation as well as the oil and gas end-markets. Revenues in the first quarter of 2013 derived from the power end-market declined moderately in absolute terms, despite the decrease in the proportional weight of this end-market.

The breakdown of E&C revenues by different business activities, types of contracts and end-markets tends to vary from period to period due to a variety of factors, including the timing of the execution of larger projects in any particular period, which is typically outside of our control.

Gross Profit. Our E&C gross profit increased 44.1%, or S/.37.1 million, from S/.84.1 million for the first quarter of 2012 to S/.121.2 million for the first quarter of 2013. Our E&C gross margin for the first quarter of 2013 was 13.6% compared to 11.7% for the first quarter of 2012. This increase in E&C gross margin was due to both the growth in revenue in this segment as well as higher margins in contract mining due to the stage of execution of certain projects, as we typically obtain higher margins during the early stages of these projects.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between the end of 2012 and the first quarter of 2013 resulted in an increase in our E&C cost of sales, as expressed in nuevos soles, of approximately S/.1.3 million, or 0.2%, during the first quarter of 2013

Operating Profit. Our E&C operating profit increased 55.6%, or S/.28.1 million, from S/.50.5 million for the first quarter of 2012 to S/.78.6 million for the first quarter of 2013. Our E&C administrative expenses increased 50.1%, or S/.16.6 million, which resulted in administrative expenses as a percentage revenues of 5.6% for the first quarter of 2013 compared to 4.6% for the first quarter of 2012, due in part to the consolidation of Vial y Vives, in which we acquired a controlling interest in October 2012, in addition to an increase of administrative expenses in line with the growth of revenues for the period. Our E&C operating profit for the first quarter of 2013 was positively impacted by S/.7.1 million in other income from compensation received in connection with a government claim related to a project completed in 2011 in the amount of S/.2.3 million, as well as the reversal of provisions in connection with the Vial y Vives acquisition in the amount of S/.4.6 million. Our E&C operating margin for the first quarter of 2013 was 8.8% compared to 7.0% for the first quarter of 2012.

In addition, our E&C segment had S/.14.6 million in profit from minority interests held by Vial y Vives in two projects undertaken in Chile, which is reflected under “share of profit and loss in associates” in our interim unaudited consolidated financial statements.

Total		127.8		127.7		(0.1	)

Our Infrastructure revenues decreased 0.1% or S/.0.1 million, from S/.127.8 million for the first quarter of 2012 to S/.127.7 million for the first quarter of 2013. The variation in our Infrastructure revenues principally reflected the following:

• Toll Roads: a 4.5%, or S/.1.3 million, increase in revenues, from S/.28.6 million for the first quarter of 2012 to S/.29.9 million for the first quarter of 2013, primarily due to a 4.3% increase in vehicular traffic in Norvial;

• Mass Transit: a 20.3%, or S/.3.6 million, increase in revenues, from S/.17.7 million for the first quarter of 2012 to S/.21.3 million for the first quarter of 2013, primarily due to a full quarter of operation of the Lima Metro in 2013 compared to the first quarter of 2012 in which we undertook trial runs during the month of January;

• Water Treatment: a 9.0%, or S/.1.0 million, increase in revenues, from S/.11.1 million for the first quarter of 2012 to S/.12.1 million for the first quarter of 2013, primarily due to progress in the construction of the La Chira waste water treatment plant; and

• Energy: a 8.5%, or S/.6.0 million, decrease in revenues, from S/.70.4 million for the first quarter of 2012 to S/.64.4 million for the first quarter of 2013 primarily due to lower production at our gas processing plant due to a decline in demand from EEPSA as a result of higher rainfall during this period and, to a lesser extent, lower levels of dispatch of fuel in our fuel storage terminals, partially offset by higher levels of oil production during the quarter.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between the end of 2012 and the first quarter of 2013 resulted in an increase in our Infrastructure revenues, as expressed in nuevos soles, of approximately S/.0.5 million, or 0.4%, during the first quarter of 2013.

Our Infrastructure gross profit decreased 12.1%, or S/.5.3 million, from S/.43.9 million for the first quarter of 2012 to S/.38.6 million for the first quarter of 2013. Our Infrastructure gross margin was 30.2% for the first quarter of 2013 compared to 34.4% for the first quarter of 2012. The variation in our Infrastructure gross profit principally reflected the following:

• Toll Roads: a 3.2%, or S/.0.4 million, increase in gross profit, from S/.12.6 million for the first quarter of 2012 to S/.13.0 million for the first quarter of 2013. This increase was primarily due to the increase in revenues from Norvial. Our Toll Roads gross margin was 43.5% for the first quarter of 2013 compared to 44.1% for the first quarter of 2012;

• Mass Transit: a 72.7%, or S/.0.8 million decrease in gross profit, from S/.1.1 million gross profit for the first quarter of 2012 to S/.0.3 million gross profit for the first quarter of 2013, primarily due to an increase in costs in preparation for the entry into operation of new trains for the Lima Metro;

• Water Treatment: a 77.8%, or S/.0.7 million, increase in gross profit for first quarter of 2013, from S/.0.9 million gross profit for the first quarter of 2012 to S/.1.6 million gross profit for the first quarter of 2013, primarily due to the progress of the construction of the La Chira waste water treatment plant. Our Water Treatment gross margin was 13.2% for the first quarter of 2013 compared to 8.1% for the first quarter of 2012; and

• Energy: a 19.1%, or S/.5.6 million, decrease in gross profit, from S/.29.3 million for the first quarter of 2012 to S/.23.7 million for the first quarter of 2013, primarily due to the decline in Energy revenues. Our Energy gross margin was 36.8% for the first quarter of 2013 compared to 41.6% for the first quarter of 2012.

Our Infrastructure operating profit decreased 14.4%, or S/.5.2 million, from S/.36.1 million for the first quarter of 2012 to S/.30.9 million for the first quarter of 2013. Our Infrastructure operating margin was 24.2% for the first quarter of 2013 compared to 28.3% for the first quarter of 2012. The variation in our Infrastructure operating profit principally reflected the following:

• Toll Roads: a 5.6%, or S/.0.6 million, increase in operating profit, from S/.10.7 million for the first quarter of 2012 to S/.11.3 million for the first quarter of 2013, primarily due to the increase in gross profit in Norvial. Our Toll Roads operating margin was 37.8% for the first quarter of 2013 compared to 37.4% for the first quarter of 2012;

• Mass Transit: a 20%, or S/.0.3 million, increase in operating loss, from an operating loss of S/.1.5 million for the first quarter of 2012 to an operating loss of S/.1.8 million for the first quarter of 2013, due to the decrease in gross profit. The operating losses in the first quarters 2012 and 2013 relate to the limited number of trains we operated during these initial periods;

• Water Treatment: a 87.5%, or S/.0.7 million, increase in operating profit, from S/.0.8 million for the first quarter of 2012 to an operating profit of S/.1.5 million for the first quarter of 2013, due to the increase in gross profit. Our Water Treatment operating margin for the first quarter of 2013 was 12.4% compared to 7.2% for the first quarter of 2012; and

• Energy: a 24.0%, or S/.6.3 million, decrease in operating profit, from S/.26.2 million for the first quarter of 2012 to S/.19.9 million for the first quarter of 2013, primarily due to the decrease in gross profit. Our Energy operating margin was 30.9% for the first quarter of 2013 compared to 37.2% for the first quarter of 2012.

Real Estate

Revenues. Our Real Estate revenues increased 122.4%, or S/.25.7 million, from S/.21.0 million for the first quarter of 2012 to S/.46.7 million for the first quarter of 2013. This increase was primarily due to an 85.4% increase in the number of affordable housing units delivered, with 304 units delivered in the first quarter of 2013 compared to 164 units delivered in the first quarter of 2012.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between the end of 2012 and the first quarter of 2013 resulted in an increase in our Real Estate revenues, as expressed in nuevos soles, of approximately S/.24,000, or 0.1%, during the first quarter of 2013.

Gross Profit. Our Real Estate gross profit increased 247.2%, or S/.13.1 million, from S/.5.3 million for the first quarter of 2012 to S/.18.4 million for the first quarter of 2013, mainly as a result of higher gross margins in our Real Estate segment, primarily as a result of higher prices at one of our affordable housing developments and higher sales volumes. Our Real Estate gross margin was 39.4% for the first quarter of 2013 compared to 25.2% for the first quarter of 2012.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between the end of 2012 and the first quarter of 2013 resulted in an increase in our Real Estate cost of sales, as expressed in nuevos soles, of approximately S/.30,000, or 0.1%, during the first quarter of 2013.

Our Technical Services revenues decreased 7.9%, or S/.20.9 million, from S/.265.0 million for the first quarter of 2012 to S/.244.1 million for the first quarter of 2013. The variation in our Technical Services revenues principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 15.3%, or S/.10.9 million, decrease in revenues, from S/.71.1 million for the first quarter of 2012 to S/.60.2 million for the first quarter of 2013, primarily due to the expiration of two road maintenance contracts and lower revenues from three road maintenance contracts which were in final stages during the period, partially offset by increased revenues from three road maintenance contracts that were awarded at the end of 2012.

• IT Services: a 15.3%, or S/.7.1 million, increase in revenues, from S/.46.4 million for the first quarter of 2012 to S/.53.5 million for the first quarter of 2013, primarily as a result of new information technology and outsourcing projects; and

• Electricity Networks Services: a 11.6%, or S/.17.1 million, decrease in revenues, from S/.147.5 million for the first quarter of 2012 to S/.130.4 million for the first quarter of 2013, primarily due to the closure of CAM’s electrical products sales division as part of our restructuring of the business.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between the end of 2012 and the first quarter of 2013 resulted in an increase in our Technical Services revenues, as expressed in nuevos soles, of approximately S/.153,000, or 0.1%, during the first quarter of 2013. We estimate that fluctuations among the nuevo sol and the Chilean peso between the end of 2012 and the first quarter of 2013 resulted in an increase in our Technical Services revenues, as expressed in nuevos soles, of approximately S/.2.8 million, or 2.2%, during the first quarter of 2013.

Our Technical Services gross profit increased 27.6%, or S/.8.5 million, from S/.30.8 million for the first quarter of 2012 to S/.39.3 million for the first quarter of 2013. Our Technical Services gross margin was 16.1% for the first quarter of 2013 compared to 11.6% for the first quarter of 2012. The variation in our Technical Services gross profit principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 10.2%, or S/.1.3 million, decrease in gross profit, from S/.12.7 million for the first quarter of 2012 to S/.11.4 million for the first quarter of 2013, primarily due to the decrease in revenues. Our Operation and Maintenance of Infrastructure Assets gross margin was 18.9% for the first quarter of 2013 compared to 17.9% for the first quarter of 2012;

• IT Services: a 52.8%, or S/.3.8 million, increase in gross profit, from S/.7.2 million for the first quarter of 2012 to S/.11.0 million for the first quarter of 2013, primarily related to growth in revenues and, in particular, higher margin services. Our IT Services gross margin was 20.6% for the first quarter of 2013 compared to 15.5% for the first quarter of 2012; and

• Electricity Networks Services: a 55.0%, or S/.6.0 million, increase in gross profit, from S/.10.9 million for the first quarter of 2012 to S/.16.9 million for the first quarter of 2013, primarily due to restructuring initiatives to improve the operating processes of CAM subsequent to our acquisition of a controlling interest in the business. Our Electricity Networks Services gross margin was 13.0% for the first quarter of 2013 compared to 7.4% for the first quarter of 2012.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between the end of 2012 and the first quarter of 2013 resulted in an increase in our Technical Services cost of sales, as expressed in nuevos soles, of approximately S/.177,000, or 0.2%, during the first quarter of 2013. We estimate that fluctuations among the nuevo sol and the Chilean peso between the end of 2012 and the first quarter of 2013 resulted in an increase in our Technical Services cost of sales, as expressed in nuevos soles, of approximately S/.2.4 million, or 2.2%, during the first quarter of 2013.

Our Technical Services operating profit decreased 31.4%, or S/.6.4 million, from S/.20.4 million for the first quarter of 2012 to S/.14.0 million for the first quarter of 2013. Our Technical Services operating margin for the first quarter of 2013 was 5.7% compared to 7.7% for the first quarter of 2012. The variation in our Technical Services operating profit principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 79.0%, or S/.7.9 million, decrease in operating profit, from S/.10.0 million for the first quarter of 2012 to S/.2.1 million for the first quarter of 2013, primarily due to an increase in costs related to the preparation of infrastructure concession bids. Our Operation and Maintenance of Infrastructure Assets operating margin was 3.5% for the first quarter of 2013 compared to 14.1% for the first quarter of 2012;

• IT Services: a 100.0%, or S/.2.8 million, increase in operating profit, from S/.2.8 million for the first quarter of 2012 to S/.5.6 million for the first quarter of 2013, primarily due to the increase the gross profit. Our IT Services operating margin was 10.5% for the first quarter of 2013 compared to 6.0% for the first quarter of 2012; and

• Electricity Networks Services: a 17.1%, or S/.1.3 million, decrease in operating profit, from S/.7.6 million for the first quarter of 2012 to S/.6.3 million for the first quarter of 2013, primarily due to lower reversal of provisions in the first quarter of 2013 (S/.3.9 million) than in the first quarter of 2012 (S/.11.9 million) in connection with the CAM acquisition which offset the increase in gross profit between the two periods, as described in “—Factors Affecting Our Results with Operation—Acquisitions.” Our Electricity Network Services operating margin was 4.8% for the first quarter of 2013 compared to 5.2% for the first quarter of 2012.

Financial (Expense) Income, Net

Our net financial expense increased S/.25.2 million from net financial income of S/.2.4 million in the first quarter of 2012 to net financial expenses of S/.22.8 million in the first quarter of 2013. Excluding foreign exchange differences, our net financial expense increased 60.7%, or S/.3.4 million, from net financial expenses of S/.5.6 million for the first quarter of 2012 to net financial expenses of S/.9.0 million for the first quarter of 2013. This increase was primarily due to an increase in indebtedness incurred mainly to finance our investments in the Lima Metro from S/.633.1 million as of March 31, 2012 to S/.925.4 million as of March 31, 2013. Our exchange difference, net decreased S/.21.7 million, from a gain of S/.7.9 million for the first quarter of 2012 to a loss of S/.13.8 million for the first quarter of 2013. The depreciation of the nuevo sol against the U.S. dollar from the end of 2012 through the first quarter of 2013, resulted in an exchange loss on our income statement due to the effect on our U.S.-dollar liabilities as expressed in nuevos soles.

Income Tax

Our income tax increased 13.2%, or S/.4.7 million, from S/.35.5 million for the first quarter of 2012 to S/.40.2 million for the first quarter of 2013. This increase in income tax was primarily due to an increase in profit before tax. Our effective tax rates for the first quarters of 2012 and 2013 were 33.0% and 32.5%, respectively.

Net Profit

Our net profit increased 15.7%, or S/.11.3 million, from S/.72.1 million for the first quarter of 2012 to S/.83.4 million for the first quarter of 2013. Net profit attributable to controlling interests decreased 1.4%, while net profit attributable to non-controlling interests increased 180.9%. Net profit attributable to non-controlling interests increased primarily as a result of the consolidation of Vial y Vives not included in the first quarter of 2012, which is 26% owned by a minority investor, and a significantly higher percentage of minority interests in developments undertaken by Viva GyM. See “—General—Accounting for Subsidiaries, Joint Operations and Associated Companies.”

Revenues

Our total revenues increased by 23.4%, or S/.990.6 million, from S/.4,241.3 million for 2011 to S/.5,231.9 million for 2012. This increase was due to growth in each of our business segments, particularly our E&C segment.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between 2011 and 2012 resulted in a decrease in our consolidated revenues, as expressed in nuevos soles, of approximately S/.168.9 million, or 3.1%, during 2012, as the nuevo sol appreciated against the U.S. dollar by approximately 4.2% and the nuevo sol depreciated against the Chilean peso by approximately 4.9%.

The following table sets forth a breakdown of our revenues by segment for 2011 and 2012.

Cost of Sales

Our total cost of sales increased by 25.2%, or S/.910.3 million, from S/.3,609.5 million for 2011 to S/.4,519.8 million for 2012. This increase was primarily related to the growth in our revenues and, to a lesser extent, an increase in costs in our Technical Services segment, as described below.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between 2011 and 2012 resulted in a decrease in our consolidated cost of sales, as expressed in nuevos soles, of approximately S/.113.5 million, or 2.4%, during 2012.

Gross Profit

Our gross profit increased by 12.7%, or S/.80.3 million, from S/.631.7 million for 2011 to S/.712.1 million for 2012. Our gross margin for 2012 was 13.6% compared to 14.9% for 2011. This decrease in our gross margin was primarily due to the full year impact of CAM in our Technical Services segment which reduced our margins in that segment and resulted in a decrease of 140 basis points in our consolidated gross margin; changes in the mix of contracting arrangements in our E&C segment with the proportion of less risky contracts for us (i.e., cost-plus fee and, to a lesser extent, unit price) increasing, thereby depressing our margins in that segment; and lower production and prices at our gas processing plant in our Infrastructure segment; partially offset by higher margins in our Real Estate segment. Our gross margin was also adversely affected due to expenses relating to the pre-operation phase of the Lima Metro during the second half of 2011, a period during which we did not generate revenues, and, in 2012, as a result of the limited number of trains we operated during the first year of operation.

The following table sets forth a breakdown of our gross profit by segment for 2011 and 2012.

	Year ended December 31,												Variation

Total		631.7			100.0			712.1			100.0			12.7

Administrative Expenses

Our administrative expenses increased by 28.9%, or S/.57.6 million, from S/.199.6 million for 2011 to S/.257.2 million for 2012, primarily due to the expansion of our administrative structure to support the growth of our business in each of our segments, particularly in our E&C segment. As a percentage of revenues, our administrative expenses grew to 4.9% in 2012 from 4.7% in 2011.

Other Income (Expenses)

Our other income (expenses) increased S/.71.6 million, from S/.4.3 million for 2011 to S/.75.9 million for 2012. This increase was primarily due to the reversal in 2012 of S/.72.8 million in provisions recognized in connection with our acquisition of a controlling interest in CAM. In addition, in 2011, we recognized a S/.45.2 million gain from sale of business combination in connection with the excess of the fair value of the assets and liabilities acquired in the CAM acquisition over the consideration paid, which is reflected under “gain from business combination.” For further information, see “—Factors Affecting Our Results of Operations—Acquisitions” and notes 25 and 28(c) to our audited annual consolidated financial statements included in this prospectus.

Operating Profit

Our operating profit increased 9.7%, or S/.47.0 million, from S/.483.6 million for 2011 to S/.530.6 million for 2012. Our operating margin (i.e., operating profit as a percentage of revenues) was 10.1% for 2012 compared to 11.4% for 2011, reflecting the decrease in gross margin, as well as higher administrative expenses in 2012 in our E&C segment relating to our acquisition of Vial y Vives; and extraordinary income in 2011 for Concar in our Technical Services segment arising from a S/.7.2 million arbitration award related to the Arequipa-Matarani road. Excluding the effects of the CAM acquisition, our operating profit increased by 8.1% and our operating margin for 2012 was 10.13% compared to 11.4% for 2011.

The following table sets forth a breakdown of our operating profit by segment for 2011 and 2012.

Business Segments

The following discussion analyzes our key results of operations on a segment basis. For further information on our business segments, see note 5 to our audited annual consolidated financial statements included in this prospectus.

Engineering and Construction

The table below sets forth selected financial information related to our E&C segment.

	Year ended December 31,				Variation
	2011		2012
	(in millions of S/.)				%
Revenues		2,784.2		3,524.6		26.6
Gross profit		329.3		408.0		23.9
Operating profit		227.5		247.6		8.8

Revenues. Our E&C revenues increased 26.6%, or S/.740.4 million, from S/.2,784.2 million for 2011 to S/.3,524.6 million for 2012, primarily due to a greater number of projects undertaken and an increase in average project size, driven by economic growth and increased investment in Peru.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our E&C revenues, as expressed in nuevos soles, of approximately S/.116.3 million, or 3.2%, during 2012.

The following describes variations in our E&C revenues by business activities, types of contracts and end-markets:

E&C Activities: For 2012, approximately 5.4%, 26.5%, 25.4%, 21.6% and 21.1% of our E&C revenues were derived from engineering services, electromechanic construction, civil construction, contract mining and building construction activities, respectively. For 2011, approximately 4.4%, 16.9%, 35.8%, 15.1% and 27.9% of our E&C revenues were derived from engineering construction, electromechanic construction, civil construction, contract mining and building construction activities, respectively. Revenues relating to

86

electromechanic construction increased in part as a result of the temporary postponement in the execution of certain projects during 2011, and revenues relating to contract mining activity increased mainly as a result of an increase in project awards and the consolidation of Stracon GyM. Revenues in 2012 from civil construction declined moderately in absolute terms, and revenues from building construction were flat in absolute terms, despite the decrease in the proportional weight of these activities. For a description of our E&C business activities, see “Business—Engineering and Construction—Principal Engineering and Construction Activities”;

E&C Contracts: For 2012, approximately 37.9%, 48.5%, 5.0% and 8.6% of our E&C revenues were derived from cost-plus fee, unit price, lump-sum and EPC contracts, respectively. For 2011, approximately 23.9%, 61.7%, 14.2% and 0.2% of our E&C revenues were derived from cost-plus fee, unit price, lump-sum and EPC contracts, respectively. The growth in cost-plus fee contracts resulted in part from a trend towards the use of this contractual arrangement for complex projects. For a description of our contractual arrangements, see “Business—Engineering and Construction—Contracts” and “—Factors Affecting Our Results of Operations—Engineering and Construction”; and

E&C End-Markets: For 2012, approximately 40.0%, 18.7%, 16.2%, 8.7%, 9.4%, 2.2% and 4.8%, of our E&C revenues were derived from mining, real estate buildings, power, oil and gas, transportation, water and sewage, and other end-markets, respectively. For 2011, approximately 40.3%, 27.5%, 9.8%, 4.0%, 12.1%, 5.1% and 1.2%, of our E&C revenues were derived from mining, real estate buildings, power, oil and gas, transportation, water and sewage, and other end-markets, respectively. During 2012 we continued to derive significant revenues from the mining sector, and we experienced growth in revenues particularly from the power as well as the oil and gas sectors. Revenues in 2012 derived from the real estate and transportation end-markets declined moderately in absolute terms, despite the decrease in the proportional weight of these end-markets.

The breakdown of E&C revenues by different business activities, types of contracts and end-markets tends to vary from year to year due to a variety of factors, including the timing of the execution of larger projects in any particular year, which is typically outside of our control.

Gross Profit. Our E&C gross profit increased 23.9%, or S/.78.7 million, from S/.329.3 million for 2011 to S/.408.0 million for 2012. The increase in our E&C cost of sales was largely in line with our revenue growth in this segment. Our E&C gross margin for 2012 was 11.6% compared to 11.8% for 2011. Our E&C gross margin was affected by the trend in our contractual arrangements toward less risky contracts for us (i.e., cost-plus fee and, to a lesser extent, unit price) which provide more stable results at lower profit margins. See “—Factors Affecting Our Results of Operations—Engineering and Construction.”

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our E&C cost of sales, as expressed in nuevos soles, of approximately S/.67.0 million, or 2.1%, during 2012.

Operating Profit. Our E&C operating profit increased 8.8%, or S/.20.1 million, from S/.227.5 million for 2011 to S/.247.6 million for 2012. Our E&C administrative expenses increased 53.2%, or S/.55.5 million, which resulted in administrative expenses as a percentage revenues of 4.5% for 2012 compared to 3.7% for 2011, due in part to extraordinary costs, including restructuring costs, incurred related to our acquisition of Vial y Vives. Our E&C operating profit was also impacted by S/.2.6 million in other income in 2011 and S/.0.6 million in other expenses in 2012, in each case from the sale of equipment and machinery. Our E&C operating margin for 2012 was 7.0% (7.1% excluding Vial y Vives) compared to 8.2% for 2011.

Our Infrastructure revenues increased 29.7%, or S/.120.2 million, from S/.404.2 million for 2011 to S/.524.5 million for 2012. The variation in our Infrastructure revenues principally reflected the following:

• Toll Roads: a 7.1%, or S/.8.2 million, increase in revenues, from S/.115.2 million for 2011 to S/.123.3 million for 2012, primarily due to an increase in vehicular traffic in Norvial of 7.4% from 2011 to 2012, which resulted in an increase of revenues of S/.7.0 million, and, to a lesser extent, the initiation of periodic maintenance services in Survial;

• Mass Transit: S/.73.1 million in revenues for 2012, resulting from the initiation of operations of the Lima Metro in January 2012;

• Water Treatment: S/.41.0 million in revenues for 2012, resulting from the commencement of the engineering design of La Chira waste water treatment plant in March 2012; and

• Energy: a 0.7%, or S/.2.0 million, decrease in revenues, from S/.289.0 million for 2011 to S/.287.0 million for 2012 primarily due to lower production and sales prices in 2012 in our gas processing plant; partially offset by higher prices and, to a lesser extent, higher production in our oil extraction services. Our gas processing plant had high production levels and sales prices in 2011 as a result of the high energy requirements of EEPSA due to lower rainfall during the year.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our Infrastructure revenues, as expressed in nuevos soles, of approximately S/.11.4 million, or 2.1%, during 2012.

Our Infrastructure gross profit increased 18.1%, or S/.26.4 million, from S/.146.2 million for 2011 to S/.172.6 million for 2012. Our Infrastructure gross margin was 32.9% for 2012 compared to 36.2% for 2011. The variation in our Infrastructure gross profit principally reflected the following:

• Toll Roads: a 32.9%, or S/.13.2 million, increase in gross profit, from S/.40.1 million for 2011 to S/.53.3 million for 2012. This increase was primarily due to costs incurred by Survial in 2011, without corresponding revenues, with respect to the performance of certain periodic maintenance services prior to the government’s approval, with the government approving periodic maintenance work to begin in October 2012. Our Toll Roads gross margin was 43.2% for 2012 compared to 34.8% for 2011;

• Mass Transit: a S/.7.2 million decrease in gross loss, from a S/.9.9 million gross loss for 2011 to a S/.2.7 million gross loss for 2012, primarily due to losses in 2011 as a result of cost of sales incurred in the pre-operation phase of the Lima Metro during the second half of the year, a period during which we did not generate revenues, and, in 2012, as a result of the limited number of trains we operated during the first year of operation. However, we have recently ordered 19 additional trains and, when these trains begin to operate, we expect to generate gross profit from the Lima Metro;

• Water Treatment: S/.11.2 million in gross profit for 2012, due to the commencement of the engineering design of La Chira waste water treatment plant. Our Water Treatment gross margin for 2012 was 27.2%; and

• Energy: a 4.4%, or S/.5.1 million, decrease in gross profit, from S/.116.0 million for 2011 to S/.110.8 million for 2012, primarily due to decreased activity at our gas processing plant in 2012 compared to 2011. Our Energy gross margin was 38.6% for 2012 compared to 40.1% for 2011.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our Infrastructure cost of sales, as expressed in nuevos soles, of approximately S/.4.1 million, or 1.1%, during 2012.

Operating Profit. The table below sets forth the breakdown of our Infrastructure operating profit by principal lines of business.

	Year ended December 31,						Variation

Energy		100.5			93.6			(6.9	)
Total		118.3			139.7			18.1

Our Infrastructure operating profit increased 18.1%, or S/.21.4 million, from S/.118.3 million for 2011 to S/.139.7 million for 2012. Our Infrastructure operating margin was 26.6% for 2012 compared to 29.3% for 2011. The variation in our Infrastructure operating profit principally reflected the following:

• Toll Roads: a 42.0%, or S/.13.9 million, increase in operating profit, from S/.33.1 million for 2011 to S/.47.0 million for 2012, primarily due to the increase in our Toll Roads gross profit and, to a lesser extent, a reduction in administrative expenses at Survial as we are able to achieve efficiencies across our toll road concessions. Our Toll Roads operating margin was 38.1% for 2012 compared to 28.8% for 2011;

• Mass Transit: a S/.4.5 million lower operating loss, from an operating loss of S/.15.1 million for 2011 to an operating loss of S/.10.6 million for 2012. The operating losses in 2011 relate to expenses incurred in the pre-operation phase of the Lima Metro in the second half of 2011, a period during which we did not generate revenues, and, in 2012, as a result of the limited number of trains we operated during the first year of operation;

89

• Water Treatment: a S/.9.9 million increase in operating profit, from an operating loss of S/.(0.3) million for 2011 to an operating profit of S/.9.7 million for 2012, due to the commencement of the engineering design of La Chira waste water treatment plant. Our Water Treatment operating margin for 2012 was 23.6%; and

• Energy: a 6.9%, or S/.6.9 million, decrease in operating profit, from S/.100.5 million for 2011 to S/.93.6 million for 2012, primarily due to the decrease in gross margin. Our Energy operating margin was 32.6% for 2012 compared to 34.8% for 2011.

Real Estate

The table below sets forth selected financial information related to our Real Estate segment.

	Year ended December 31,				Variation
	2011		2012
	(in millions of S/.)				%
Revenues		152.3		240.1		57.7
Gross profit		45.3		86.7		91.3
Operating profit		34.9		67.6		93.6

Revenues. Our Real Estate revenues increased 57.7%, or S/.87.8 million, from S/.152.3 million for 2011 to S/.240.1 million for 2012. This increase was primarily due to a 10.0% increase in the number of affordable housing and housing units delivered, with 1,368 units delivered in 2012 compared to 1,244 units delivered in 2011; and a shift in the mix of units delivered towards housing (as opposed to affordable housing) units, which have higher prices per unit; as well as an increase in land parcels sold by Almonte. We generated S/.10.1 million in 2011 and S/.45.6 million in 2012 from the sale of land parcels by Almonte.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our Real Estate revenues, as expressed in nuevos soles, of approximately S/.3.3 million, or 1.3%, during 2012.

Gross Profit. Our Real Estate gross profit increased 91.3%, or S/.41.4 million, from S/.45.3 million for 2011 to S/.86.7 million for 2012, primarily as a result of the land parcel sales by Almonte at a significant increase in land prices compared to the book value at which we had these assets recorded in our financial statements of S/.2.1 million. Our Real Estate gross margin was 36.1% for 2012 compared to 29.8% for 2011. Excluding the sale of land parcels by Almonte, our Real Estate gross profit increased 25.3% and our Real Estate gross margin was 24.0% for 2012 compared to 25.9% for 2011. This decrease in gross margin, after excluding the sales of land parcels by Almonte, was primarily due to costs in certain commercial real estate projects that initiated operations in 2012.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our Real Estate cost of sales, as expressed in nuevos soles, of approximately S/.5.7 million, or 3.6%, during 2012.

Operating Profit. Our Real Estate operating profit increased 93.6%, or S/.32.7 million, from S/.34.9 million for 2011 to S/.67.6 million for 2012, primarily as a result of the increase in our Real Estate gross profit described above. Our Real Estate operating margin was 28.1% for 2012 compared to 22.9% for 2011. Excluding the sale of land parcels by Almonte, our Real Estate operating margin was 14.0% for 2012 compared to 18.6% for 2011, primarily due to the lower gross margin and marketing costs in 2012 relating to a greater number of housing projects initiated in 2012.

Electricity Networks Services		558.2		632.5		13.3
Total		977.0		1,083.3		10.9

Our Technical Services revenues increased 10.9%, or S/.106.4 million, from S/.977.0 million for 2011 to S/.1,083.3 million for 2012. The variation in our Technical Services revenues principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 4.2%, or S/.9.9 million, increase in revenues, from S/.232.9 million for 2011 to S/.242.8 million for 2012, primarily due to the addition of three new road maintenance contracts related to 1,165 km of roads awarded at the end of 2012, which we expect to have a greater impact on our revenues in 2013;

• IT Services: a 11.9%, or S/.22.1 million, increase in revenues, from S/.185.9 million for 2011 to S/.208.0 million for 2012, primarily as a result of economic growth of Peru, with government entities and businesses increasingly outsourcing IT services to focus on their core functions which led to both additional clients as well as additional activity for existing clients; and

• Electricity Networks Services: a 13.3%, or S/.74.3 million, increase in revenues, from S/.558.2 million for 2011 to S/.632.5 million for 2012, primarily due to the consolidation of revenues for CAM for a full year in 2012 compared to ten months in 2011.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our Technical Services revenues, as expressed in nuevos soles, of approximately S/.4.5 million, or 1.0%, during 2012. We estimate that fluctuations among the nuevo sol and the Chilean peso between 2011 and 2012 resulted in a decrease in our Technical Services revenues, as expressed in nuevos soles, of approximately S/.33.4 million, or 5.1%, during 2012.

Our Technical Services gross profit decreased 5.2%, or S/.5.7 million, from S/.109.7 million for 2011 to S/.103.9 million for 2012. Our Technical Services gross margin was 9.6% for 2012 compared to 11.2% for 2011. The variation in our Technical Services gross profit principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 26.0%, or S/.14.4 million, decrease in gross profit, from S/.55.6 million for 2011 to S/.41.2 million for 2012, primarily due to the higher margins we obtained in 2011 as a result of the initiation of services of contracts awarded at the end of 2010. In general, the initiation of a road maintenance contract (i.e., bringing the road to proper operating condition) generates higher margins than subsequent routine maintenance; accordingly, we expect higher gross profit in 2013 with the addition of three new road maintenance contracts at the end of 2012. Our Operation and Maintenance of Infrastructure Assets gross margin was 16.9% for 2012 compared to 23.9% for 2011;

• IT Services: a 31.8%, or S/.9.4 million, increase in gross profit, from S/.29.6 million for 2011 to S/.39.0 million for 2012, primarily related to growth in revenues and, in particular, higher margin services. Our IT Services gross margin was 18.8% for 2012 compared to 15.9% for 2011; and

• Electricity Networks Services: a 3.2%, or S/.0.8 million, decrease in gross profit, from S/.24.5 million for 2011 to S/.23.7 million for 2012, primarily due to costs incurred in connection with certain contracts entered into by CAM prior to our acquisition of a controlling interest in it. We will seek to improve the Electricity Networks Services gross margin as we continue to integrate the business and implement further restructuring initiatives by improving operating processes to enhance efficiencies. Our Electricity Networks Services gross margin was 3.8% for 2012 compared to 4.4% for 2011.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2011 and 2012 resulted in a decrease in our Technical Services cost of sales, as expressed in nuevos soles, of approximately S/.4.6 million, or 1.2%, during 2012. We estimate that fluctuations among the nuevo sol and the Chilean peso between 2011 and 2012 resulted in a decrease in our Technical Services cost of sales, as expressed in nuevos soles, of approximately S/.32.1 million, or 5.1%, during 2012.

Operating Profit. The table below sets forth the breakdown of our Technical Services operating profit by principal lines of business.

Our Technical Services operating profit decreased 19.3%, or S/.17.3 million, from S/.89.4 million for 2011 to S/.72.2 million for 2012. Our Technical Services operating margin for 2012 was 6.7% compared to 9.2% for 2011. The variation in our Technical Services operating profit principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 63.4%, or S/.31.4 million, decrease in operating profit, from S/.49.6 million for 2011 to S/.18.1 million for 2012, primarily due to the decrease in our gross profit and an increase in costs relating to the preparation of concession bids, as well as a S/.7.2 million gain in 2011 resulting from an arbitration award related to the Arequipa-Matarani road. Our Operation and Maintenance of Infrastructure Assets operating margin was 7.5% for 2012 compared to 21.3% for 2011;

• IT Services: a 29.3%, or S/.4.2 million, increase in operating profit, from S/.14.4 million for 2011 to S/.18.6 million for 2012, primarily due to the increase in gross profit. Our IT Services operating margin was 8.9% for 2012 compared to 7.7% for 2011; and

92

• Electricity Networks Services: a 39.1%, or S/.10.0 million, increase in operating profit, from S/.25.5 million for 2011 to S/.35.5 million for 2012, primarily due to the effects of the reversal of provisions in connection with the CAM acquisition, as described in “—Factors Affecting Our Results with Operations—Acquisitions,” which offset the decrease in gross profit. Our Electricity Networks Services operating margin was 5.6% for 2012 compared to 4.6% for 2011.

Financial (Expense) Income, Net

Our net financial expense increased 68.0%, or S/.4.2 million, from net financial expenses of S/.6.2 million in 2011 to net financial expenses of S/.10.3 million in 2012. Excluding exchange difference, our net financial expense increased 290.9%, or S/.23.4 million, from net expenses of S/.8.0 million for 2011 to net expenses of S/.31.5 million for 2012. This increase was primarily due to an increase in indebtedness incurred to finance our investments from S/.529.8 million as of December 31, 2011 to S/.845.5 million as of December 31, 2012. Our exchange difference, net increased S/.19.2 million, from a gain of S/.1.9 million for 2011 to a gain of S/.21.1 million for 2012. This increase in gain from exchange difference, net was primarily due to the appreciation of the nuevo sol versus the U.S. dollar in 2012, which decreased the value of our U.S. dollar liabilities in nuevos soles. For a breakdown of our financial expenses and income, see note 24 to our audited annual consolidated financial statements included in this prospectus.

Income Tax

Our income tax increased 9.3%, or S/.13.1 million, from S/.141.4 million for 2011 to S/.154.6 million for 2012. This increase in income tax was primarily due to an increase in profit before income tax. Our effective tax rates for 2012 and 2011 were 29.7% and 29.6%, respectively.

Net Profit

Our net profit increased 8.9%, or S/.30.1 million, from S/.336.2 million for 2011 to S/.366.3 million for 2012. Net profit attributable to controlling interests increased 0.3%, while net profit attributable to non-controlling interests increased 61.9%. Net profit attributable to non-controlling interests increased primarily as a result of the consolidation in 2012 of the results of Stracon GyM, as compared to the 2011 accounting for Stracon GyM as a joint operation, whereby we only recognized our share of the revenues and expenses from the joint operation, as well as the 49.6% non-controlling interest in Almonte, which provided significant profit from the sale of land parcels in 2012. See “—General—Accounting for Subsidiaries, Joint Operations and Associated Companies.”

Revenues

Our total revenues increased by 69.5%, or S/.1,738.6 million, from S/.2,502.7 million for 2010 to S/.4,241.3 million for 2011. This increase was primarily due to growth in each of our segments other than Real Estate, in particular our E&C segment, as well as our acquisition of a controlling interest in CAM in February 2011. Excluding the revenues generated from the CAM acquisition, our total revenues would have increased 47.2%.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between 2010 and 2011 resulted in a decrease in our consolidated revenues, as expressed in nuevos soles, of approximately S/.47.2 million, or 1.1%, during 2011, as the nuevo sol appreciated against the U.S. dollar by approximately 2.5% and the nuevo sol depreciated against the Chilean peso by approximately 2.9%.

Cost of Sales

Our total cost of sales increased by 75.4%, or S/.1,551.7 million, from S/.2,057.8 million for 2010 to S/.3,609.5 million for 2011. The increase was primarily related to the growth in our revenues, as well as the effect of the acquisition of a controlling interest in CAM, as described below.

We estimate that fluctuations among the nuevo sol and the U.S. dollar and the Chilean peso between 2010 and 2011 resulted in a decrease in our consolidated cost of sales, as expressed in nuevos soles, of approximately S/.21.9 million, or 0.6%, during 2011.

Gross Profit

Our gross profit increased by 42.0%, or S/.186.9 million, from S/.444.8 million for 2010 to S/.631.7 million for 2011. Our gross margin was 14.9% for 2011 compared to 17.8% for 2010. Our gross margin in 2011 was impacted by the inclusion of the results of CAM in our Technical Services segment, which resulted in a decrease of 160 basis points in our consolidated gross margin; changes in contractual arrangements in our E&C segment; and, to a lesser extent, expenses incurred in the pre-operation phase of the Lima Metro in our Infrastructure segment in the second half of 2011, which resulted in a decrease of 240 basis points in our consolidated gross margin. Excluding the effects of the acquisition of a controlling interest in CAM, our gross profit increased by 36.5% and our gross margin was 16.5% for 2011.

The following table sets forth a breakdown of our gross profit by segment for 2010 and 2011.

Administrative Expenses

Our administrative expenses increased by 62.1%, or S/.76.4 million, from S/.123.2 million for 2010 to S/.199.6 million for 2011, primarily due to the acquisition of a controlling interest in CAM. As a percentage of revenues, our administrative expenses decreased to 4.7% in 2011 from 4.9% in 2010.

Other Income (Expenses)

Our other income increased S/.1.6 million, from income of S/.2.7 million for 2010 to income of S/.4.3 million for 2011. This increase was primarily related to the sale of machinery and equipment in 2011.

Operating Profit

Our operating profit increased 21.0%, or S/.84.0 million, from S/.399.5 million for 2010 to S/.483.6 million for 2011. Our operating margin was 11.4% for 2011 compared to 16.0% for 2010. This decrease in operating margin was primarily due to a gain in 2010 of S/.58.0 million from the sale of the Larcomar shopping center, which resulted in an increase of 230 basis points in our consolidated operating margin in 2010; and compensation received from the expropriation of oil and gas assets in Bolivia of S/.17.0 million, which resulted in an increase of 70 basis points in our consolidated operating margin in 2010; partially offset by a gain of S/45.2 million as a result of the excess of the fair value of the assets and liabilities we acquired in the CAM acquisition over the

95

consideration paid, as described in “—Factors Affecting Our Results of Operations—Acquisitions,” which resulted in an increase of 110 basis points in our consolidated operating margin in 2011. Excluding these effects, our operating profit increased 35.1% and our operating margin for 2011 was 10.3% compared to 13.0% for 2010.

Revenues. Our E&C revenues increased 63.7%, or S/.1.083.7 million, from S/.1,700.5 million for 2010 to S/.2,784.2 million for 2011, primarily due to a greater number of projects undertaken and an increase in average project size related to economic growth and increased investment in Peru.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our E&C revenues, as expressed in nuevos soles, of approximately S/.53.3 million, or 1.9%, during 2011.

The following describes variations in our E&C revenues by business activities, types of contracts and end-markets:

E&C Activities: For 2011, approximately 4.4%, 16.9%, 35.8%, 15.0% and 27.9% of our E&C revenues were derived from engineering services, electromechanic construction, civil construction, contract mining and building construction, respectively. For 2010, approximately 5.7%, 23.0%, 33.6%, 17.4% and 20.0% of our E&C revenues were derived from engineering, electromechanic construction, civil construction, contract mining and building construction, respectively. Revenues in 2011 derived from electromechanic construction, increased in absolute terms compared to 2010 despite the decrease in the proportional weight of the activity. Revenues in 2011 derived from building construction increased significantly due mainly to the execution of several large-scale projects during the year;

96

E&C Contracts: For 2011, approximately 23.9%, 61.7%, 14.2% and 0.2% of our E&C revenues were derived from cost-plus fee, unit price, lump-sum and EPC contracts, respectively. For 2010, approximately 9.8%, 66.8%, 23.4% and 0% of our E&C revenues were derived from cost-plus fee, unit price, lump-sum and EPC contracts, respectively. The growth in cost-plus fee contracts resulted in part from a trend towards the use of this contractual arrangement for complex projects;

E&C End-Markets: For 2011, approximately 40.3%, 27.5%, 9.8%, 4.0%, 12.9%, 5.1% and 1.2% of our E&C revenues were derived from mining, real estate buildings, power, oil and gas, transportation, water and sewage, and other end-markets, respectively. For 2010, approximately 38.9%, 20.8%, 11.1%, 2.8%, 22.0%, 2.6% and 1.8%, of our E&C revenues were derived from mining, real estate buildings, power, oil and gas, transportation, water and sewage, and other end-markets, respectively. During 2011 we continued to derive significant revenues from the mining sector, and we experienced growth in revenues from the real estate sector. Revenues in 2011 derived from the transportation end-market declined in part because of the completion of the construction of certain highways in 2010.

The breakdown of E&C revenues by different business activities, types of contracts and end-markets tends to vary from year to year due to a variety of factors, including the timing of the execution of larger projects in any particular year, which is typically outside of our control.

Gross Profit. Our E&C gross profit increased 42.6%, or S/.98.4 million, from S/.230.9 million for 2010 to S/.329.3 million for 2011. Our E&C gross margin was 11.8% for 2011 compared to 13.6% for 2010. Our E&C gross margin was affected by the trend in our contractual arrangements towards less risky contracts for us (i.e., cost-plus fee and, to a lesser extent, unit price) which provide more stable results at lower profit margins. See “—Factors Affecting Our Results of Operating—Engineering and Construction.”

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our E&C cost of sales, as expressed in nuevos soles, of approximately S/.30.4 million, or 1.2%, during 2011.

Operating Profit. Our E&C operating profit increased 51.9% or S/.77.7 million, from S/.149.8 million for 2010 to S/.227.5 million for 2011. Our E&C operating margin was 8.2% for 2011 compared to 8.8% for 2010. E&C operating margin was primarily affected by the effect of our E&C gross margin, partially offset by S/.2.6 million in other income in 2011 from the sale of equipment and machinery compared to S/.1.5 million in 2010.

Our Infrastructure revenues increased 14.0%, or S/.49.5 million, from S/.354.7 million for 2010 to S/.404.2 million for 2011. We did not have revenues from our Mass Transit or Water Treatment businesses in 2010 and 2011. The variation in our Infrastructure revenues principally reflected the following:

• Toll Roads: a 0.3%, or S/.0.3 million, increase, from S/.114.9 million for 2010 to S/.115.2 million for 2011, primarily due to an increase in vehicular traffic in Norvial of 10.6% from 2010 to 2011; partially offset by a S/.18.4 million gain in Survial in 2010 related to the financing of the construction of the road. See “—Factors Affecting Our Results of Operations—Infrastructure—Traffic and Fees for Toll Roads”; and

• Energy: a 20.5%, or S/.49.2 million, increase, from S/.239.8 million for 2010 to S/.289.0 million for 2011, primarily due to an increase in oil prices and, to a lesser extent, oil production.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our Infrastructure revenues, as expressed in nuevos soles, of approximately S/.6.7 million, or 1.6%, during 2011.

Our Infrastructure gross profit increased 10.5%, or S/.13.9 million, from S/.132.3 million for 2010 to S/.146.2 million for 2011. Our Infrastructure gross margin was 36.2% for 2011 compared to 37.3% for 2010. The variation in our Infrastructure gross profit principally reflected the following:

• Toll Roads: a 24.7%, or S/.13.1 million, decrease, from S/.53.3 million for 2010 to S/.40.1 million for 2011. Our Toll Roads gross margin was 34.8% for 2011 compared to 46.4% for 2010. In 2010, Survial had a gain of S/.18.4 million related to the financing of the construction of the road and, in 2011, Survial incurred costs, without corresponding revenues, with respect to the performance of certain periodic maintenance services prior to the government’s approval;

• Mass Transit: cost of sales of S/.9.9 million for 2011 relating to the pre-operation phase of the Lima Metro, a period during which we did not generate revenues; and

• Energy: a 46.7%, or S/.36.9 million, increase, from S/.79.1 million for 2010 to S/.116.0 million for 2011. Our Energy gross profit increased primarily due to increase in global oil prices. Our Energy gross margin was 40.1% for 2011 compared to 33.0% for 2010.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our Infrastructure cost of sales, as expressed in nuevos soles, of approximately S/.2.3 million, or 0.9%, during 2011.

Our Infrastructure operating profit decreased 8.2%, or S/.10.6 million, from S/.128.9 million for 2010 to S/.118.3 million for 2011. Our Infrastructure operating margin was 29.3% for 2011 compared to 36.3% for 2010. The variation in our Infrastructure operating profit principally reflected the following:

• Toll Roads: a 24.8 %, or S/.11.0 million, decrease, from S/.44.1 million for 2010 to S/.33.1 million for 2011, primarily due to the effects of the Toll Roads gross profit. Our Toll Roads operating margin was 28.8% for 2011 compared to 38.4% for 2010;

• Mass Transit: a S/.15.1 million operating loss for 2011, relating to costs incurred during the pre-operation phase of the Lima Metro, a period during which we did not generate revenues; and

• Energy: a 18.5%, or S/.15.7 million, increase, from S/.84.8 million for 2010 to S/.100.5 million for 2011. Our Energy operating margin was 34.8% for 2011 compared to 35.3% for 2010. Our Energy operating margin for 2010 was positively affected by a gain of S/.17.0 million in compensation for the expropriation of oil and gas assets in Bolivia.

Real Estate

Gross profit		33.3		45.3		36.0
Operating profit		26.7		34.9		30.7

Revenues. Our Real Estate revenues decreased 30.3%, or S/.66.3 million, from S/.218.6 million for 2010 to S/.152.3 million for 2011. This decrease was primarily due to a 41.9% decrease in the number of housing units delivered, with 1,244 units delivered in 2011 compared to 2,142 units delivered in 2010 as a result of the timing of the completion and delivery of our real estate projects; partially offset by the sale of land parcels by Almonte in 2011 which generated S/.10.1 million.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our Real Estate revenues, as expressed in nuevos soles, of approximately S/.1.2 million, or 0.8%, during 2011.

Gross Profit. Our Real Estate gross profit increased 36.0%, or S/.12.0 million, from S/.33.3 million for 2010 to S/.45.3 million for 2011, due to higher margins obtained in two affordable housing projects, as well as the sale of land parcels by Almonte in 2011, which reflected a significant appreciation in price compared to the book value recorded in our financial statements of S/.0.7 million. Our Real Estate gross margin was 29.8% for 2011 compared to 15.2% for 2010. Excluding the sale of land parcels by Almonte, our Real Estate gross profit increased 10.4% and our Real Estate gross margin was 25.9% for 2011.

99

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our Real Estate cost of sales, as expressed in nuevos soles, of approximately S/.2.3 million, or 2.1%, during 2011.

Operating Profit. Our Real Estate operating profit increased 30.7%, or S/.8.2 million, from S/.26.7 million for 2010 to S/.34.9 million for 2011. Our Real Estate operating margin was 22.9% for 2011 compared to 12.2% for 2010. Our Real Estate operating margin was primarily affected by the effect of our Real Estate gross margin. Excluding the sale of land parcels by Almonte, our Real Estate operating margin was 18.6% for 2011.

Electricity Networks Services		—		558.2		N/M
Total		285.0		977.0		242.8

Our Technical Services revenues increased 242.8%, or S/.692.0 million, from S/.285.0 million for 2010 to S/.977.0 million for 2011, in large part as a result of the acquisition of a controlling interest in CAM. Excluding the revenues generated by CAM, our Technical Services revenues increased 47.2%. The variation in our Technical Services revenues principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 62.0%, or S/.89.1 million, increase, from S/.143.8 million for 2010 to S/.232.9 million for 2011, primarily due to three additional public-sector road contracts related to 2,872 km awarded at the end of 2010, which we began to execute in 2011;

• IT Services: a 31.6% or S/.44.7 million, increase, from S/.141.2 million for 2010 to S/.185.9 million for 2011, primarily as a result of economic growth of Peru, with government entities and businesses increasingly outsourcing IT services to focus on their core functions, which led to both additional clients as well as increased activity for existing clients; and

• Electricity Networks Services: S/.558.2 million in revenues in 2011 resulting from the CAM acquisition in February 2011.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our Technical Services revenues, as expressed in nuevos soles, of approximately S/.2.4 million, or 0.6%, during 2011. We estimate that fluctuations among the nuevo sol and the Chilean peso between 2010 and 2011 resulted in an increase in our Technical Services revenues, as expressed in nuevos soles, of approximately S/.16.3 million, or 2.9%, during 2011.

Our Technical Services gross profit increased 79.7%, or S/.48.6 million, from S/.61.0 million for 2010 to S/.109.7 million for 2011. Our Technical Services gross margin was 11.2% for 2011 compared to 21.4% for 2010, primarily as a result of our acquisition of a controlling interest in CAM, which generates significantly lower margins than our other lines of business. The variation in our Technical Services gross profit principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 58.9%, or S/.20.6 million, increase, from S/.35.0 million for 2010 to S/.55.6 million for 2011. Our Operation and Maintenance of Infrastructure Assets gross margin was 23.9% for 2011 compared to 24.3% for 2010;

• IT Services: a 13.5%, or S/.3.5 million, increase in gross profit from S/.26.1 million for 2010 to S/.29.6 million for 2011. Our IT Services gross margin was 15.9% for 2011 compared to 18.4% for 2010. This decrease in gross margin was primarily due to an extraordinary penalty payment in 2011 resulting from a fire at the facilities of one of our clients; and

• Electricity Networks Services: S/.24.5 million in gross profit in 2011 resulting from our acquisition of a controlling interest in CAM. Our Electricity Networks Services gross margin was 4.4% for 2011.

We estimate that fluctuations among the nuevo sol and the U.S. dollar between 2010 and 2011 resulted in a decrease in our Technical Services cost of sales, as expressed in nuevos soles, of approximately S/.2.4 million, or 0.7%, during 2011. We estimate that fluctuations among the nuevo sol and the Chilean peso between 2010 and 2011 resulted in a decrease in our Technical Services cost of sales, as expressed in nuevos soles, of approximately S/.15.6 million, or 2.9%, during 2011.

Our Technical Services operating profit increased 135.8%, or S/.51.5 million, from S/.37.9 million for 2010 to S/.89.4 million for 2011. Our Technical Services operating margin was 9.2% for 2011 compared to 13.3 % for 2010. The variation in our Technical Services operating profit principally reflected the following:

• Operation and Maintenance of Infrastructure Assets: a 95.8%, or S/.24.3 million, increase, from S/.25.3 million for 2010 to S/.49.6 million for 2011, primarily due to an increase in our Operation and Maintenance of Infrastructure Assets gross profit; as well as a S/.7.2 million gain in 2011 resulting from an arbitration award related to the Arequipa-Matarani road. Our Operation and Maintenance of Infrastructure Assets operating margin was 21.3% for 2011 compared to 17.6% for 2010;

101

• IT Services: a 13.9%, or S/.1.7 million, increase, from S/.12.6 million for 2010 to S/.14.4 million for 2011, primarily related to an increase in our IT Services gross profit. Our IT Services operating margin was 7.7% for 2011 compared to 8.9% for 2010; and

• Electricity Networks Services: S/.25.5 million in operating profit in 2011 resulting from our acquisition of a controlling interest in CAM in 2011. Our Electricity Networks Services operating margin was 4.6% for 2011. Our operating profit was affected by a S/.45.2 million gain from the excess of the fair value of assets and liabilities acquired in the CAM acquisition over the price paid, as described in “—Factors Affecting Our Results of Operation—Acquisitions.”

Financial (Expense) Income, Net

Our net financial expense decreased 38.4%, or S/.3.8 million, from net financial expenses of S/.10.0 million in 2010 to net financial expenses of S/.6.2 million in 2011. Excluding exchange difference, our net financial expense decreased 55.8%, or S/.10.2 million, from net financial expenses of S/.18.2 million for 2010 to net financial expenses of S/.8.1 million for 2011. This decrease was primarily due to an increase in interest on short-term bank deposits as a result of higher deposit amounts. Our exchange difference, net decreased 76.9%, or S/.6.3 million, from a gain of S/.8.2 million for 2010 to a gain of S/.1.9 million for 2011. This decrease was primarily due to the depreciation of the Chilean peso versus the nuevo sol in 2011, which decreased the value of the Chilean peso assets in CAM in nuevos soles, partially offset by the appreciation of the nuevo sol versus the U.S. dollar during the year. For a breakdown of our financial expenses, see note 24 to our audited annual consolidated financial statements included in this prospectus.

Income Tax

Our income tax increased 13.8%, or S/.17.1 million, from S/.124.3 million for 2010 to S/.141.4 million for 2011. The increase was primarily due to an increase in profit before income tax. Our effective tax rates for 2011 and 2010 were 29.6% and 31.0%, respectively.

Net Profit

Our net profit increased 21.5%, or S/.59.5 million, from S/.276.7 million for 2010 to S/.336.2 million for 2011. Net profit attributable to controlling interests increased 14.3%, while net profit attributable to non-controlling interests increased 97.3%. Net profit attributable to non-controlling interests increased primarily as a result of the consolidation of our 75.0% interest in CAM and a greater percentage of minority interests in Viva GyM as a result of increased non-controlling interests used to finance our real estate projects.

Liquidity and Capital Resources

Our principal sources of liquidity have historically been cash flows from operating activities and, to a lesser extent, indebtedness. Our principal uses of cash (other than in connection with our operating activities) have historically been: capital expenditures in all our business segments, including acquisitions and investments in our infrastructure concessions; servicing of our debt; and payment of dividends. We believe that these sources of cash will be sufficient to cover our working capital needs in the ordinary course of business. We believe that our cash from operations, the net proceeds from this offering and our current financing sources are sufficient to satisfy our current capital expenditures and debt service obligations in 2013 and 2014. We anticipate financing future acquisitions, infrastructure investments and land purchases with a combination of cash from operations, net proceeds from the offering, additional indebtedness and/or financial contributions from partners.

At March 31, 2013, our cash and cash equivalents totaled S/.653.0 million (US$252.2 million), of which S/.94.0 million (US$36.3 million) was held by our foreign subsidiaries. We currently intend to distribute these funds to our company to the extent we believe they are not required for the local operations. We are not currently required to accrue or pay any material taxes associated with the repatriation of these funds. In addition, our foreign subsidiaries have no contractual restrictions, and we are not aware of any material legal restrictions, on their ability to transfer funds to us in the form of cash dividends, loans or advances.

(4) Our investments in 2011 of S/.75.1 million related to the Lima Metro (other than for trains) and S/.5.8 million related to La Chira waste water treatment plant are presented in the table above under “Infrastructure” as opposed to “Corporate” as recorded in our consolidated financial statements.

(5) Includes S/.117.5 million, S/.70.7 million, and S/.126.8 million in investments in 2010, 2011 and 2012 respectively, for the purchase of land by our Real Estate segment, which in accordance with IFRS are recorded in our consolidated financial statements as “inventory.”

(6) In our consolidated financial statements, in accordance with IFRS, we record as “cash flow used in investing activities” with respect to equipment leases only the amounts paid during the period as opposed to the total amount of lease payments which is included in the table above. In 2010, 2011, 2012 and the first quarter of 2013, the differences between the amounts reflected in the table above and the amounts reflected in our consolidated cash flow statements for our Technical Services segment amounted to S/4.4 million, S/.(34.6) million, S/(9.2) million and S/.(0.6) million, respectively.

Capital expenditures for our E&C segment of approximately S/.127.1 million (US$45.2 million), S/.183.7 million (US$68.1 million), S/.417.1 million (US$163.5 million) and S/.36.8 million (US$14.2 million) in 2010, 2011, 2012 and the first quarter of 2013, respectively, primarily correspond to the purchase of equipment and machinery and, to a lesser extent, investments relating to mining services contracts. In 2012, capital investments in this segment also include S/.141.8 million (US$55.6 million) with respect to the acquisition of a majority stake in Vial y Vives. Capital expenditures for our Infrastructure segment of approximately S/.52.6 million (US$18.7 million), S/.172.0 million (US$63.8 million), S/.301.9 million (US$118.3 million) and S/.122.1 million (US$47.2 million) in 2010, 2011, 2012 and the first quarter of 2013, respectively, correspond to periodic maintenance relating to our Norvial toll road concession and, in our Energy line of business, oil development drilling activities

and, in 2012 and the first quarter of 2013, improvements for our gas processing plant. In 2011, 2012 and the first quarter of 2013, capital expenditures for our Infrastructure segment also included the purchase of trains for Line One of the Lima Metro and the construction of the railway maintenance and repair yard. Capital expenditures for our Real Estate segment of approximately S/.124.1 million (US$44.2 million), S/.73.6 million (US$27.3 million), S/.128.3 million (US$50.3 million) and S/.1.0 million (US$0.4 million) in 2010, 2011, 2012 and the first quarter of 2013, respectively, primarily correspond to the purchase of land for real estate projects, including the Cuartel San Martín, Parque de Comas, Cispreses, Carabayllo and Villa El Salvador projects in 2010, the Parques de Caqueta and Pezet projects in 2011, the Villa El Salvador, Barranco, San Isidro office building and Parques de Callao projects in 2012. Capital expenditures for our Technical Services segment of approximately S/.30.9 million (US$11.0 million), S/.57.5 million (US$21.3 million), S/.39.8 million (US$15.6 million) and S/.8.9 million (US$3.4 million) in 2010, 2011, 2012 and the first quarter of 2013, respectively, primarily correspond to maintenance of equipment relating to Concar, CAM and GMD. In 2011, capital investments in this segment also include S/.29.1 million (US$10.8 million) with respect to the acquisition of a controlling stake in CAM.

Divestitures in 2010 consisted of approximately S/.149.9 million (US$53.4 million) relating primarily to the sale of the Larcormar shopping center for S/.107.0 million (US$38.1 million) and the San Isidro office building for S/.10.0 million (US$3.6 million), as well as compensation received from the expropriation of our oil and gas assets in Bolivia. Divestitures in 2011 consisted of approximately S/.33.0 million (US$12.2 million) relating to the sale of our participation in the IIRSA South and North concessions. Divestitures in 2012 consisted of approximately S/.23.5 million (US$9.1 million) relating to the sale of equipment from GyM to Stracon GyM. We had no divestitures during the first quarter of 2013 nor any currently in progress.

We have budgeted S/.1,218.9 million (US$470.8 million) in capital expenditures for 2013. Our current plans for our E&C segment contemplate capital expenditures in 2013 of approximately S/.240.6 million (US$92.9 million) mainly for the purchase of equipment and machinery. Our current plans for our Infrastructure segment contemplate capital expenditures in 2013 of approximately S/.387.0 million (US$149.5 million) principally for the purchase of additional trains and the construction of the maintenance and repair yard in connection with the Lima Metro as well as for investments in oil development drilling activities. Our current plans for our Real Estate segment contemplate capital expenditures in 2013 of approximately S/.212.5 million (US$82.1 million) for the purchase of land for real estate development projects. Our current plans for our Technical Services segment contemplate capital expenditures in 2013 of approximately S/.51.2 million (US$19.8 million) principally for the purchase of equipment used in our operations. Our current plans for our Corporate segment contemplate capital expenditures in 2013 of approximately S/.327.6 million (US$126.5 million), including S/.225.3 million (US$87.0 million) for potential acquisitions, S/.70.8 million (US$27.3 million) for new infrastructure concessions, and S/.31.5 million (US$12.2 million) for the construction of a new office building for corporate use. As we determine the capital expenditures currently reflected in our Corporate segment, we will assign these expenditures to the corresponding segment.

These estimates are subject to change. We routinely evaluate acquisitions, new infrastructure concessions, land purchases and other investment opportunities that are aligned with our strategic goals. We cannot assure you that we will find opportunities on terms that we consider to be favorable to us, whether we will be able to take advantage of such opportunities should they arise, or the timing of and funds required by such opportunities. In addition, we expect to finance these opportunities with a combination of cash on hand, net proceeds from this offering, new borrowings and/or financial contributions from partners, depending on a variety of commercial considerations at such time. See “Forward-Looking Statements.”

Cash Flows

The table below sets forth certain components of our cash flows for 2010, 2011, 2012 and the first quarters of 2012 and 2013.

Cash Flow from Operating Activities

Net cash flow used in operating activities in the first quarter of 2013 was higher than in first quarter of 2012. For the first quarter of 2013 this reflects a decrease in other accounts payable of S/.22.7 million related to advance payments from clients in our E&C segment, an increase in other accounts receivable of S/.73.4 million mainly related to the purchase of trains for the Lima Metro, and a decrease in accounts payable of S/.129.8 million mainly in our E&C and Real Estate segment. Additionally, cash flow provided by operating activities was used to pay taxes in the amount of S/.119.8 million.

For the first quarter of 2012 we experienced an increase in other accounts receivables of S/.152.4 million primarily due to the purchase of trains for the Lima Metro, an increase in inventory of S/.54.3 million mainly due to the purchase of land for our Real Estate segment, and a decrease in other accounts payable to related parties of S/.57.4 million due to the reimbursement of cash to our joint operations and associates. In addition, we experienced an increase in accounts payable of S/.86.1 million and an increase in other accounts payable of S/.52.4 million due to an increase in advance payments from clients in our E&C segment. Additionally, cash flow provided by operating activities was used to pay taxes in the amount of S/.92.3 million.

Net cash flow provided by operating activities in 2012 was significantly higher than in 2011. This primarily reflects an increase in trade accounts payable of S/.224.9 million principally related to payments due to suppliers in our E&C segment mainly related to growth in our operations, and other accounts payable of S/.373.6 million mainly related to an increase in advance payments from clients of our E&C, Technical Services and Infrastructure segments, partially offset by an increase in other accounts receivables of S/.346.4 million mainly related to the purchase of trains for the Lima Metro in an amount equal to S/.305.8 million and an increase in inventory of S/.196.6 million mainly due to the purchase of land in our Real Estate segment in an amount equal to S/.126.8 million. Additionally, cash flow provided by operating activities was used to pay taxes in the amount of S/.159.4 million.

Net cash flow provided by operating activities in 2011 was significantly lower than in 2010, principally due to the high rate of organic growth (47.2% excluding the acquisition of a controlling interest in CAM) in our business during 2011. This growth is primarily reflected in an increase in trade accounts receivable of S/.177.1 million, an increase in inventory of S/.140.4 million mainly related to the purchase of land as well as construction in our Real Estate segment and an increase in trade accounts payable of S/.265.6 million. In addition, in 2011 we experienced a decrease of S/.68.5 million in other accounts payable principally related to a decline in advance payments from clients in our E&C and Technical Service segments as a result of the timing of the completion of projects and an increase in other accounts receivable of S/.183.5 million mainly due to an increase in our advance payments to suppliers and guarantee deposit for contracts in our E&C segment. Additionally, cash flow provided by operating activities was used to pay taxes in the amount of S/.139.3 million.

Net cash flow provided by operating activities in 2010 reflects an increase in accounts receivables of S/.66.2 million, an increase in inventory of S/.46.4 million, an increase in accounts payable of S/.28.3 million and an increase in other accounts payable of S/.123.6 million mainly related to advance payments from clients in our

105

E&C and Technical Service segment, partially offset by a reduction of S/.70.3 million in other accounts payable to related parties due to reimbursement of cash to our joint operations and associates in our E&C segment. Additionally, cash flow provided by operating activities was used to pay taxes in the amount of S/.19.8 million.

Cash Flow from Investing Activities

Net cash flow used in investing activities in the first quarter of 2013 was lower than in the first quarter of 2012. This primarily reflects a lower amount of purchases of machinery and equipment.

Net cash flow used in investing activities in 2012 was significantly higher than in 2011. This primarily reflects an increase in payments for investment purchases in 2012, principally related to the acquisition of Vial y Vives, higher investment in oil drilling activities and a greater amount of purchases of machinery and equipment. Net cash flow used in investing activities in 2011 was significantly higher than in 2010, primarily due to the cash inflow in 2010 from the sale of the Larcomar shopping center and compensation received from the expropriation of our oil and gas assets in Bolivia, while in 2011 we acquired CAM, purchased a greater amount of machinery and equipment and made higher investments in oil drilling activities.

Cash Flow from Financing Activities

Net cash flow provided by financing activities in the first quarter of 2013 was higher than in first quarter of 2012. This primarily reflects increased borrowing under our syndicated loan in February 2013 in connection with the Lima Metro.

Net cash flow used in financing activities in 2012 was lower than in 2011. This primarily reflects an increased indebtedness incurred during the year. Net cash flow used in financing activities in 2011 was lower than in 2010. This primarily reflects higher indebtedness incurred in 2011, partially offset higher debt service payments and higher dividends paid during the year.

Indebtedness

As of March 31, 2013, we had a total outstanding indebtedness of S/.925.4 million (US$357.4 million) as set forth in the table below.

As of May 31, 2013, S/.94.9 million (US$36.6 million) of our total indebtedness indicated in the table above has matured, of which S/.47.1 million (US$18.2 million) was repaid and S/.47.8 million (US$18.5 million) was renewed by extending the maturities. In addition, we incurred S/.170.4 million (US$65.8 million) of additional indebtedness related to our syndicated loan. The weighted average interest rate of this renewed indebtedness and additional indebtedness was 6.5% and the maturity dates ranged from June 6, 2013 to February 27, 2018.

Below is a description of our material outstanding indebtedness as of March 31, 2013. As of March 31, 2013, we were in compliance in all material respects with the financial covenants corresponding to our outstanding indebtedness.

We expect to finance future infrastructure investments, acquisitions and land purchases with a combination of cash from operations, net proceeds from this offering, new indebtedness and/or financial contributions from partners. Accordingly, we expect to incur additional indebtedness in the future.

Leasing. As of March 31, 2013, we were party to numerous leasing agreements with several financial institutions which in the aggregate amounted to approximately S/.323.1 million (US$124.8 million). We entered into such agreements primarily for the purpose of leasing the equipment and other assets necessary to run our operations. Upon maturity of each leasing agreement, we have the option to purchase or return the equipment or assets to the lessor. The amounts owed under these leasing agreements are generally repaid in monthly installments, subject to a minimum guaranteed payment corresponding to the minimum amount for which the equipment or assets could be sold to a third-party.

BBVA Banco Continental Bridge Loan. As of December 31, 2012, Graña y Montero had a short-term unsecured loan with BBVA Banco Continental entered into on October 5, 2012 in an outstanding principal amount of approximately US$60.7 million. This loan accrued interest at an annual rate of three month LIBOR plus 3.80% and matured in March 2013. The proceeds of the loan were used by our subsidiary GyM Ferrovías to purchase trains and other infrastructure assets. This loan was repaid on March 5, 2013 with proceeds from the syndicated loan described below.

Syndicated Loan. On February 27, 2013, Graña y Montero entered into a syndicated loan with certain lenders and BBVA Bancomer S.A., Institución de Banca Múltiple, Grupo Financiero BBVA Bancomer, as administrative agent, for an aggregate amount of up to US$150 million, to be used to repay the US$60 million bridge loan entered into with BBVA Banco Continental, for investments in and funding the operations of GyM Ferrovías and other general corporate purposes. As of the date of this prospectus, we had US$90 million outstanding under this loan. This loan accrues interest at an annual rate of three month LIBOR plus 4.25% and matures on February 27, 2018. Certain of our subsidiaries (GyM, GMP, Concar and Viva GyM) are guarantors under the loan. The agreement contains certain customary covenants, including restrictions on our and our guarantor subsidiaries’ ability to pay dividends if in default and the obligation to maintain the following financial covenants during the term of the agreement: (1) Borrower Consolidated Adjusted Debt Coverage Ratio (as defined therein) for the preceding four quarter period shall be less than 3.00:1.00 as of the end of each fiscal quarter; (2) Guarantor Consolidated Adjusted Debt Coverage Ratio (as defined therein), calculated for each guarantor, for the preceding four quarter period shall be less than 2.50:1.00 as of the end of each fiscal quarter; and (3) Consolidated Net Worth (as defined therein) as of the end of each fiscal quarter shall be at least equal to S/.1,292.8 million.

Citibank, N.A. Secured Loan. Our subsidiary GMP has a secured loan with Citibank, N.A. under a loan agreement dated September 19, 2008 and amended on August 27, 2012 in an outstanding principal amount of S/.68.3 million (US$26.4 million) as of March 31, 2013. This loan accrues interest at an annual rate of three month LIBOR plus: (i) 1.75% if, at the installment payment date, the exchange rate between the nuevo sol and U.S. dollar remains between S/.2.60 to S/.2.75 per US$1.00 or (ii) 1.95%, if otherwise. The loan matures in August 2020. The proceeds of the loan were used by our subsidiary GMP to finance the construction, equipment and operation of the Gas Pariñas plant in Talara. The agreement is secured by certain land, equipment and accounts receivable of GMP. The agreement contains certain customary covenants, including restrictions on the ability of GMP to pay dividends if it is in default under the loan and the obligation by GMP to maintain the following financial covenants during the

107

term of the agreement: (1) Leverage Ratio (as defined therein) shall not be greater than 1.50; (2) Debt Service Coverage Ratio (as defined therein) shall not be less than 1.20; (3) Liquidity Ratio (as defined therein) shall not be less than 1.10; and (4) Debt Coverage Ratio (as defined therein) shall not be greater than 2.20.

Inter-American Development Bank and International Finance Corporation Loans. Norvial has two loans with the Inter-American Development Bank and with the International Finance Corporation under loan agreements entered into in April 2005, each in an outstanding principal amount of US$9.0 million as of March 31, 2013. These loans accrue interest at an annual rate of 6.9% and mature in November 2016. These loans benefit from a trust through which the cashflows from Norvial’s toll fees are collected. The proceeds of these loans were used for the construction, rehabilitation and maintenance of the Norvial road. The loan agreements contain certain customary covenants, including restrictions on Norvial’s ability to pay dividends and incur additional debt.

Derivative Financial Instruments

In February 2012, our subsidiary GyM Ferrovías entered into a forward rate agreement with BBVA S.A. for an initial amount of EUR 98.6 million to hedge the foreign exchange risk pertaining to expenditures incurred in euros to a foreign supplier for the development, maintenance and operation of the Lima Metro. GyM Ferrovías will receive EUR39.2 million outstanding under the agreement at a fixed exchange rate of S/.3.5952 per euro beginning in March 2013 and up to S/.3.6412 per euro in January 2014.

In August 2012, our subsidiary GMP entered into two interest rate swaps with Citibank, N.A. to hedge its exposure to fluctuations in LIBOR under its unsecured loan with Citibank, N.A. described above. These interest rate swaps establish a fixed annual rate of 5.05%, payable at each interest payment date under the loan.

In September 2012, our subsidiary Viva GyM entered into a forward foreign exchange agreement with Banco de Crédito del Perú to hedge the foreign exchange risk on the amount to be received in U.S. dollars as proceeds from a loan agreement with Banco de Crédito del Perú in connection with the construction of the Torre Real 8 project. Under the agreement, Viva GyM receives in nuevos soles the equivalent of US$3.6 million in 12 equal installments payments of US$300,000 determined at a fixed exchange rate of S/.2.5921 per U.S. dollar on the first installment in October 2012 and up to S/.2.6242 per U.S. dollar on the final installment in September 2013.

Off-Balance Sheet Arrangements

There are no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our results of operations, financial condition or liquidity. As of March 31, 2013, we maintain guarantee commitments with different financial institutions securing transactions for US$203.8 million and S/.26.5 million, mainly related to the purchase of additional trains for the Lima Metro. For additional information on these commitments, see note 27(c) to our audited annual consolidated financial statements and note 16 of our unaudited interim consolidated financial statements included in this prospectus.

Quantitative and Qualitative Disclosures about Market Risk

We are exposed to a number of market risks arising from our normal business activities, including the possibility that changes in currency exchange rates or interest rates will adversely affect future cash flows and profit or the value of our financial assets and liabilities. From time to time, we enter into derivative transactions to hedge against foreign currencies and interest rate fluctuations. For further information regarding our market risk, see note 3 to our audited annual consolidated financial statements included in this prospectus.

Exchange Rate Risk

We are exposed to market risk associated with changes in foreign currency exchange rates. Our revenues and costs, and our assets and liabilities, are denominated in nuevos soles, U.S. dollars, Chilean pesos and, to a lesser extent, other currencies. In 2012, 31.2%, 56.7% and 12.1% of our revenues were denominated in nuevos soles, U.S. dollars and other currencies (principally Chilean pesos), respectively, while 47.6%, 39.0% and 13.5% of our cost of sales during the year were denominated in nuevos soles, U.S. dollars and other currencies. In addition, as of December 31, 2012, 6.9%, 86.3% and 6.8% of our total debt was denominated in nuevos soles, U.S. dollars and other currencies, respectively. If, at December 31, 2012, the nuevo sol had strengthened/weakened by 10% against the U.S. dollar, with all other variables remaining constant, our net profit for the year would have increased/decreased by S/.2.0 million.

Interest Rate Risk

We may from time to time incur variable interest rate indebtedness, and accordingly our financial expenses are affected by changes in interest rates. Based upon our indebtedness at December 31, 2012, and taking into account our interest rate derivative instruments, a change in interest rates of one percent (or 100 basis points) would impact our net profit by S/.5.9 million annually. This sensitivity analysis does not take into account indebtedness that we incur subsequent to December 31, 2012.

Commodity Price Risk

We are exposed to market risk associated with changes in commodity prices, primarily for oil, steel and cement, which in aggregate represented a majority of our total input cost in 2012. We do not have long-term contracts for the supply of these key inputs. Based upon our consumption of these inputs during 2012, a 10% increase/decrease in the prices of each of oil, steel and cement would have increased/decreased our costs of sales by S/.71.0 million, S/.10.4 million and S/.5.5 million, respectively. However, based on our production of oil during 2012, a 10% increase/decrease in the price of oil would have increased/decreased our revenues by S/.82.5 million.

INDUSTRY

Our Main Market: Peru

Overview of the Peruvian Economy

Our results are substantially affected by economic conditions prevailing in Peru. The Peruvian economy has been one of the fastest growing economies globally during the period from 2008 to 2012. According to the Peruvian Central Bank, Peruvian real GDP grew at an average rate of 6.5% during that period, the highest rate in South America. The economic expansion during this period was a result of robust domestic demand, increase in investment, price stability, increase in foreign direct investment, improvement in public finances, and lower external debt, among other factors.

In addition, the country’s strong economic growth has led to a 47.8% increase in GDP per capita from US$4,427 in 2008 to US$6,543 in 2012. According to the National Statistical Institute of Peru (INEI), the country’s poverty rate (defined as the percentage of population with per capita consumption below S/.272 per month, as of May 2012) fell from 42.4% in 2007 to 27.8% in 2011 and is expected, as noted by the Peruvian Ministry of Economy and Finance, to continue declining at a steady rate. Inequality as measured by the Gini coefficient improved from 0.52 in 2007 to 0.48 in 2010, according to the World Bank. Also, the proportion of middle class families, those in socioeconomic categories B and C as measured by APOYO Consultoría, has expanded from 20.3% of total households in 2004 to 32.2% of total households in 2012.

The following table sets forth the main economic indicators of the Peruvian economy from 2008 to 2012.

Average annual inflation, measured by the change in the CPI index, was 3.3% in the period from 2008 to 2012. Peru’s price stability has also been reflected in its currency, the nuevo sol, which appreciated from an average of S/.2.93 per US$1.00 in 2008 to an average of S/.2.64 per US$1.00 in 2012, an appreciation of 9.8%. Given its sustained performance with regards to fiscal balance, debt/GDP ratio, net reserves and high liquidity (international reserves are higher than the equivalent of 18.7 months of imports of goods and services and 5.8 times the short-term debt service (which includes the portion of long term debt due that year and the short term debt, according to 2012 figures), Peru’s sovereign debt has been granted investment grade rating by S&P, Fitch and Moody’s. At the end of 2012, Peruvian sovereign debt had one of the highest credit ratings in the South American region, rated BBB by S&P (August 2011) and Fitch (October 2011) and Baa2 by Moody’s (August 2012).

As a result of the improvement in national income and the expanding middle-income population, private consumption grew at an average annual rate of 5.9% in real terms, from 2008 to 2012. Also, during this period, private investment increased at an average rate of 11.6% in real terms, driven by an increase in projects, primarily in the mining, oil and gas, electricity, transportation, telecommunications and manufacturing sectors. Additionally, total fixed investment as a percentage of GDP increased from 25.9% in 2008 to 26.7% in 2012, reflecting an overall increase in private and public investment over that period. Domestic investments flowed mainly into mining projects, the Camisea gas project, the construction of new power plants and ongoing expansions in the cement, food, power and hotel industries.

Key Industry Sectors Relating to Our Business in Peru

Construction and Infrastructure

The Peruvian construction industry GDP is estimated at US$14 billion and accounted for 7.1% of the country’s nominal GDP in 2012 according to the Peruvian Central Bank. Construction GDP grew at an average of 11.7% annually in nominal terms during the five years from 2008 to 2012. This growth has been associated with private investments in the housing, mining and manufacturing sectors as well as public projects such as toll roads, infrastructure renovation and government-sponsored housing programs such as MiVivienda and TechoPropio, run by Fondo Mivivienda (the country’s government-owned mortgage financing institution that runs the TechoPropio program and other programs, collectively referred to as MiVivienda in this prospectus). The following table illustrates that from 2008 to 2012, the average real growth rate in both private investment and construction in Peru was approximately two times the average real GDP growth rate, historically moving in the same direction as the change in the growth rate of overall real GDP.

Additionally, Peru still faces a significant infrastructure investment gap. According to the Peruvian Association for the Promotion of National Infrastructure (AFIN), the country’s infrastructure investment gap is estimated at US$88 billion for the period from 2012 to 2021, with the breakdown shown in the chart below. The greatest deficits are in power, telecommunications and roads.

Infrastructure investment gap in Peru is calculated as the amount of investment needed to increase each sector’s coverage to all the unattended users (based on a cost-per-user component to define how much investment is needed).

The Peruvian government is encouraging public-private partnerships for infrastructure concessions as a way to promote the improvement of the country’s infrastructure. Proinversión, a Peruvian state agency engaged in the

113

promotion of private investments in Peru which is the Peruvian State agency engaged in the promotion of business opportunities, estimated public and private investments in infrastructure in Peru of US$20 billion from 2011 through 2016. We believe we are well-positioned to win contracts related to these concessions. There remains a significant transportation infrastructure investment gap estimated at US$21 billion, according to the Peruvian School of Business Administration for Graduates (ESAN), which is measured as the cost needed to increase or improve the transportation network in order to meet currently unmet demand. As of April 2013, the total transportation project pipeline that will help close this gap was US$22 billion, of which US$5 billion corresponds to projects under construction or that are expected to commence construction by 2016, according to APOYO Consultoría. To facilitate infrastructure development, the government established the framework for private-public partnerships by Legislative Decree No. 1012 and its regulation by Supreme Decree No. 146-2008-EF, which envisaged public co-financing of private infrastructure initiatives. For example, the Municipality of Lima granted joint operations in which we participate two highway concessions for which we are currently negotiating definitive documentation, Vía Expresa Javier Prado and Vía Expresa Sur. We believe that our experience in operating concessions in Peru provides us with the expertise to win additional concessions and similar contracts as the government grants such concessions to foster improvements in the country’s infrastructure.

As of 2012, the national highway network in Peru consisted of 24,593 km, of which only 5,792 km have been granted in concessions through a total of 15 concessions. We are the concessionaries for three of these 15 concessions, representing approximately 1,012 km in total. The following map sets forth the road concessions granted to private companies as of 2012. For air and maritime transportation, the ports and airports’ system is comprised of nine concessions, two of which are group concessions of various airports.

The real estate industry presents several construction opportunities for us as well, since Peru still has a housing deficit of approximately two million homes, according to estimates by National Statistical Institute of Peru (INEI), and limited mortgage penetration, with mortgages representing only 4.4% of GDP in 2012, based on data from SBS and the Peruvian Central Bank. The National Statistical Institute of Peru (INEI) calculates the

114

national deficit based on the latest census data from 2007 and accounts for a lack of supply for current housing demand based on quantitative (number of families without homes) and qualitative (number of homes that do not meet basic standards of living set by the United Nations) deficits. As of December 31, 2012, we are developing 11 affordable housing projects, which are in various stages of development. We believe local banks are seeking to increase their mortgage lending, including for affordable housing.

The oil and gas infrastructure industry has seen significant growth due to the Camisea project. Additionally, state-owned Petroperú has engaged in expanding its oil transportation network (Oleoducto Nor Peruano) and refinery facilities (Refinería de Talara), with construction expected to require US$4.4 billion of investments, as estimated by Petroperú and the Ministry of Energy and Mines. We have significant experience performing the engineering and construction of oil and gas infrastructure, and plan to continue seeking future contracts in this sector.

We are the leading E&C company in Peru, as measured by revenues during 2012, according to our estimates based on Peru: The Top 10,000 Companies 2012. Other companies such as Cosapi (Peru), San Martín Contratistas Generales (subsidiary of Empresas Ica in Mexico), Ingenieros Civiles y Contratistas Generales SA (Peru) and Odebrecht (Brazil), have a significant presence in Peru. We believe we are well-positioned to maintain our leadership position.

Mining

Peru is a poly-metallic resources producer and exports several metals including silver, copper, zinc, gold and lead, among others. Peru is also a major contributor to global metal reserves. According to the U.S. Geological Survey of 2012, Peru holds 22.2% of global silver reserves, 11.2% of global copper reserves, 7.2% of global zinc reserves and 4.2% of global gold reserves as of January 2013. According to the Peruvian Central Bank, mining exports reached approximately US$27 billion and represented 58.4% of total Peruvian exports in 2012.

Companies operating in Peru’s mining sector includes major global players such as Xstrata (Las Bambas, Antamina), Barrick Gold (Alto Chicama, Pierina and Laguna Norte), Freeport (Cerro Verde), Grupo Mexico (Southern Peru), Rio Tinto (La Granja), Newmont (Yanacocha, Conga), and Glencore (Quenuales, Perubar) among others, as well as local players such as Buenaventura, Volcan, and Hochschild Mining, among others.

Upcoming mining projects comprise estimated capital expenditures of approximately US$37 billion from 2013 to 2017, according to APOYO Consultoría. There are seven mining projects currently under construction and we participate in three of these projects as the E&C contractor. This demonstrates the strong growth potential of the local mining industry as well as private-sector commitment to exploration initiatives. As of February 2013, the Peruvian Ministry of Energy and Mines estimates 46 mining projects at various stages of development involving an estimated investment of US$55 billion. We are a leading E&C company for mining projects and we believe our recent acquisition of control of Vial y Vives, which specializes in E&C for the mining sector, will strengthen our ability to compete for contracts in this sector.

Power and Utilities

The power and utilities market in Peru has shown sustained growth with maximum electricity demand reaching 5,291 MW and growing at an average annual rate of 6.0% during the five years from 2008 to 2012, according to the Economic Operations Committee of Peru’s National Interconnected System. The growth of the power and utilities market has led to the construction of power generation facilities, as well as the expansion of the power transmission and distribution network.

According to the Peruvian Ministry of Energy and Mines, Peru had an installed generation capacity of 6,968 MW as of 2012. The Peruvian market is served by 27 major generation companies. As of March 2012, the nation’s power transmission network spanned approximately 21,573 kilometers, according to OSINERGMIN. As of January 2012, there were 20 electric distribution companies across Peru.

Over the past five years, Peru has actively increased its efforts to extend electricity coverage throughout the country, particularly in rural areas. According to ESAN, the Peruvian power sector requires investments of approximately US$32 billion for the period from 2012 to 2021 to meet the country’s increased demand for power services. According to APOYO Consultoría, as of May 2013, there were 23 projects of construction/expansion of generation facilities representing a total investment of US$8.7 billion, of which 10 projects are already under construction and 10 are expected to begin construction between 2013 and 2017. According to Proinversion, an additional generation project in the southern region of Peru that requires investments of approximately US$1.2 billion is expected to be awarded this year. Furthermore, there are 8 projects in the pipeline for the power transmission sector amounting to total investments of approximately US$1 billion, of which four projects are already under construction and four are expected to begin construction between 2013 and 2017. In addition, according to Proinversion, two additional transmission projects that require investments of approximately US$0.8 billion are expected to be awarded this year. These 10 projects involve the construction of approximately 3,510 kilometers of transmission lines. Additionally, in the distribution sector, the Peruvian Ministry of Energy and Mines has developed a 10-year plan to expand the electricity coverage throughout Peru. This plan involves an investment of approximately US$1 billion in the expansion of rural electric systems from 2013-2022.

We are currently building four hydroelectric plants in Peru. Our experience in designing and building power plants, including hydro plants, as well as the services we provide to the utilities sector provide us with a foundation to seek additional contracts in Peru’s power sector as it expands in the future.

Oil and Gas

The oil and gas industry has been one of the most dynamic sectors in Peru with a sector nominal GDP average annual growth rate of 18.5% during the five years from 2008 to 2012. Oil and gas activity includes the exploration and production, and transportation and commercialization of hydrocarbon products and derivatives.

According to the Peruvian Ministry of Energy and Mines, during 2012, local production of hydrocarbons was approximately 24 MMbbl, 32 MMboe of liquefied natural gas (LNG) and 74 MMboe of natural gas. These levels have grown an average of 10.5% annually from 2008 to 2012. Peruvian gas production increased considerably since 2004, when the Camisea project, the largest gas project in Peruvian history, began operations. The Peruvian Ministry of Energy and Mines reports that as of 2011 proven reserves of oil and gas amount to 3,323 MMboe. These reserves have increased since 2007, due to increased exploration activities, as evidenced in the chart below. The Peruvian government’s reserves methodology may differ materially from the one mandated by the SEC.

The exploration and production sector is mainly served by global and regional companies including Pluspetrol, Repsol, Petrobras, BPZ Energy and Savia. Certain local companies also undertake production activities. We are involved in oil production, gas processing and fractionation, and operations of fuel storage and distribution. According to the Peruvian Ministry of Energy and Mines, state-owned Petroperú, is the largest local player in refining and transporting oil and gas (as measured by volume of oil and gas processed in 2012), operating the Talara and Conchan refineries, the North-Peruvian oil pipeline and service stations. It is currently expanding the Talara refinery, which, as of December 2012, is expected to require an investment of more than US$3 billion. There are other major projects under evaluation, such as the Gasoducto Sur Peruano (Peruvian Southern Gas Pipeline), which will cover a natural gas transport network over three Peruvian regions. According to Proinversion, as of March 2013 this project requires an estimated investment of approximately US$2.4 billion. The bidding process is expected to take place in the fourth quarter of 2013.

According to APOYO Consultoría, eleven projects in the oil and gas sector, totalling approximately US$9 billion, are under construction or are expected to begin construction by 2017. According to Proinversion five projects, totalling approximately US$3.2 billion, are expected to be awarded this year. In this context, the Peruvian Ministry of Economy and Finance expects an average real growth of the sector GDP of 10.5% during the three years from 2013 to 2015.

Real Estate

The real estate market in Peru has grown during the past 10 years as the residential market faces increased demand from a large and growing middle-income population. Activity in the real estate sector has been driven mainly by a surge in home building in Lima, which comprised 80.5% of real estate construction activity by area in Lima as of July 2012, according to the Peruvian Chamber of Construction (CAPECO). Unit sales in Lima increased by 12.0% in 2012, according to data from Tinsa. Nevertheless, according to the latest available data (based on 2007 census) from National Statistical Institute of Peru (INEI) there is a housing deficit of two million houses in Peru (or 29.1% of unmet demand). Government-sponsored housing programs, including MiVivienda and Techo Propio, aim to reduce this deficit, by helping low-income families purchase houses under fully or partially financed mechanisms. The following graph sets forth the evolution of awarded loans by each program during the period from 2008 to 2012.

117

Value of MiVivienda and TechoPropio Loans Disbursed in 2008-2012, in US$ million

Source: MiVivienda Fund statistics.

The MiVivienda and TechoPropio programs are funded by the Peruvian government and the development and sale of the housing projects is undertaken by private investors. The government defines a number of projects and units to be built and runs bidding contests among real estate developers to design and build such projects, and sell the corresponding units. We are involved in these initiatives and we compete with other real estate companies such as Los Portales, Centenario, Besco, Urbi, Imagina and Edifica. The penetration in the housing market remains low compared to other countries. The stock of mortgage loans as of 2012 represents only 4.5% of Peruvian GDP, in contrast to Chile, for instance, which shows a mortgage to GDP ratio of 17.9% for 2012. However, the stock of mortgages in Peru has been growing during recent years at an average annual rate of 22.9% during the five years from 2008 to 2012. During 2012, US$3 billion in mortgages were granted, of which 14.7% were MiVivienda and Techo Propio mortgages.

Peru’s real estate sector is expected to grow mainly due to Peru’s growing upper and middle classes, which have increased from 20.6% of households in 2004 to approximately 34.2% in 2012, representing a 107.6% increase covering approximately three million additional people, according to APOYO Consultoría.

Information Technology

The Peruvian IT market comprises three types of products/services: (1) IT services (including technical support, consulting and IT outsourcing services for firms); (2) software applications (including the development and commercialization of software programs, including both off-the–shelf and custom-made applications) many of which are custom-designed for specific industries; and (3) platforms (consisting of computer hardware and infrastructure, including equipment, basic software and communication devices). The local IT industry has been growing as technology is becoming a larger component of business processes. International Data Corporation (IDC), a market intelligence firm focused on the information technology market, estimates the IT services spending in Peru was US$395 million in 2011, excluding subcontracting, and is expected to grow at an average annual rate of 12.0% from 2012 to 2015.

The main industry players include GMD (our IT company), IBM, HP, Oracle, Cosapi Data, Optical IP, Synapsis, and major telecommunications operators such as Telefónica del Perú and Claro. The Peruvian market is expected to follow global growth based on higher demand for access to technology solutions.

(1) 2012 Projected by the IMF.

The Chilean economy grew at an average annual rate of 4.0% during the five years from 2008 to 2012 in real terms. Considering only the post-crisis period (the three years from 2010 to 2012), the annual growth rate rises to 5.9%, one of the highest in South America. This expansion was mainly driven by a strong domestic demand in real terms: fixed investment grew on average at 9.0% per year and total consumption grew on average at 5.7% per year during the five years from 2008 to 2012. Inflation has remained stable since 2010, averaging 2.9% between 2008 and 2012, in line with the Chilean Central Bank’s inflation target of 3% +/- 1%. Chile’s sovereign debt has the highest rating in the region, rated AA- by S&P (December 2012), Aa3 by Moody’s (December 2012) and A+ by Fitch (January 2012).

Key Industry Sectors Relating to Our Business in Chile

Mining

Chile has one of the most significant mining sectors in Latin America, exporting several metals, including copper, silver, gold and nickel and it is the largest producer of copper worldwide. In 2012, Chile’s copper production represented 31.6% of the world’s global production and 27.9% of the world’s copper reserves, according to the Chilean Copper Commission (COCHILCO), a specialized agency that advises the Chilean government on matters concerning the production of copper and copper byproducts and metals and industrial minerals mining, except coal and fuels.

The largest copper producer in Chile (measured by 2011 production volume) is Corporación Nacional del Cobre (CODELCO), a state-owned company and the largest copper producer worldwide. There are also several privately owned companies not owned by the Chilean government that operate mines, both local and foreign. For example, Escondida (BHP Billiton) operates the highest-producing copper mine in the world.

The pipeline of mining projects in Chile comprises approximately US$61 billion planned for the period 2013 to 2016, according to the Chilean Copper Commission (COCHILCO). Some of these projects have already

119

granted E&C contracts, several of which were granted to us, including a primary crusher for Mina Caserones, developed by Minera Lumina Copiapo. However, most have yet to contract the associated E&C work, and we believe this is an opportunity for us.

Construction and Infrastructure

In 2012, Chile’s construction industry nominal GDP was approximately US$20 billion. Chile ranked as the top Latin American country in terms of infrastructure quality, according to the 2012 Global Competitiveness Report. Despite this ranking, Chile still faces a large infrastructure investment gap, as noted by the Chilean Chamber of Construction, of approximately US$48 billion for the period from 2012 to 2016.

In Chile, E&C companies include large local players such as Salfacorp, Socovesa, Sidgo Kopers, Echeverria Izquierdo, Ingevec, Besalco, Paz and Claro Vicuña Valenzuela. Regional players in the Chilean market include Odebrecht and Techint.

Power

The Chilean power system is comprised of four grids: Sistema Interconectado del Norte Grande (SING), Sistema Interconectado Central (SIC), Sistema de Aysén and Sistema de Magallanes. The SIC and the SING grids account for approximately 99.2% of Chile’s installed power generation capacity. The Chilean energy market is controlled by the private sector in all of its three subsectors (generation, transmission and distribution). The SIC grid’s energy production reached 48,868 Gwh in 2012. As of 2011, Chile has one of the highest energy costs in the region, according to the Economic Commission for Latin America & the Caribbean (ECLAC). According to Environment Evaluation Service (SEA), a public organism engaged in the administration and assessment of the environmental impact of projects, and Central Energía, current projects include more than US$6 billion of committed investments representing an expansion of 2,764 MW in Chile’s total generation capacity. Additionally, according to the Chilean Construction Commission (Cámara Chilena de la Construcción, or CChC), there is approximately US$12 billion in potential power generation pipeline projects from 2012 to 2016, which we believe is an opportunity for our E&C and Technical Services segments. As an example, we have recently completed the construction of the transmission line of the Maitencillo Caserones mines.

(1) 2012 Projected by the IMF.

Colombian real GDP grew at an average annual rate of 3.8% during the five years from 2008 to 2012. The country’s strong economic growth is evidenced by an increase in GDP per capita from US$5,496 in 2008 to US$7,931 in 2012. Inflation has remained stable over recent years, averaging 3.8% per year from 2008 to 2012, in line with the Colombian Central Bank’s inflation target of 3% +/- 1%. Additionally, Colombia’s price stability has also been reflected in its currency, the Colombian peso, which appreciated from an average of COP 1,965.1 per US$1.00 in 2008 to an average of COP 1,798.1 per US$1.00 in 2012. Colombia’s credit ratings were upgraded in 2011 to investment grade by the three major rating agencies. Its sovereign debt currently holds BBB- rating from Fitch and S&P, and Baa3 from Moody’s. Colombia is also recognized for its investor-friendly legal regime. A study published in 2012 by the World Bank and the International Finance Corporation ranked Colombia the first in Latin America and the Caribbean, and fifth in the world in terms of investor protections.

Key Industry Sectors Relating to Our Business in Colombia

Oil and Gas

The Colombian oil and gas sector GDP has grown at an average annual real growth rate of 14.0% during the five years from 2008 to 2012. According to the Colombian National Department of Administration of Statistics (DANE), as of December 2012, this sector accounted for 5.4% of the Colombian GDP. According to the Colombian Petroleum Association (“ACP”), a trade union for private oil companies in Colombia, as of 2011, the country had overall proven reserves of 3,225 MMboe, including oil as well as natural gas, which have increased 63.5% since 2007. The ACP reserves methodology may differ from the one mandated by the SEC. Production in Colombia reached 420 MMboe during 2012, having increased 55.1% since 2008. These production levels are mainly attributed to large regional players such as Ecopetrol and Pacific Rubiales, which together accounted for 86.1% of oil production during 2012, according to Colombian Ministry of Mines and Energy. There have been significant investments in the oil and gas sector in Colombia. As an example, Ecopetrol and Pacific Rubiales have made capital expenditures of US$31 billion and US$4 billion, respectively, during the five years from 2008 to 2012, consequently increasing exploration and drilling activities that have created a vast range of opportunities

121

for engineering and construction contractors, who serve the exploration and production companies in Colombia. Several investment projects are currently focused on further developing the oil and gas infrastructure in Colombia. For instance, the expansion of the Bicentenario pipeline and the Oleoducto del Pacífico pipeline projects have total estimated investment amounts of approximately US$4 billion and US$8 billion, respectively, and are expected to be completed by 2020. Furthermore, Ecopetrol plans to invest US$80 billion from 2012 to 2020 in capital expenditures. Given our experience, we believe that we can capitalize on the expansion of the oil and gas sector in Colombia.

Infrastructure

Colombia ranked 108 of 144 countries in infrastructure quality according to the 2012 Global Competitiveness Report. According to Colombian national agencies including the Ministry of Transport, the National Infrastructure Agency and the National Planning Department, the infrastructure development plan for 2012 through 2021 envisions public and private investments of approximately US$55 billion, of which US$19 billion have been committed to projects in 2012 – 2014. According to the Colombian National Planning Department, this initiative includes US$42 billion to be spent on roads and railroads construction between 2012 and 2021, which we believe presents a future opportunity for our E&C and Infrastructure segments.

In Colombia, E&C companies include large local players such as Conalvias, Conconcreto, CSS Constructora, Construcciones Civiles, Montajes Morelco, Mincivil, Marval, Odinsa, and Constructora el Condor. Regional players in the Colombian market include Odebrecht and Empresas Ica.

Power

The Colombian power sector is comprised of a mix of government and privately owned companies. The country’s net installed capacity reached 14,478 MW, according to the Colombian Ministry of Mines and Energy, as of December 2012. As of September 2012, there were 43 electricity generation companies including several players such as EPM, Emgesa, Isagen and EEPSA. The transmission grid consists of approximately 8,738 miles of transmission lines and is comprised of nine companies. The distribution subsector is comprised of 32 distributors, mostly municipally-controlled companies.

BUSINESS

Overview

We are the largest engineering and construction company in Peru as measured by revenues during 2012, and the largest publicly-traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2012, with strong complementary businesses in infrastructure, real estate and technical services.

With 80 years of operations, we have a long track record of successfully completing the engineering and construction of many of Peru’s landmark private- and public-sector infrastructure projects, such as the Lima International Airport and the Peru LNG gas liquefaction plant, and we believe we have earned a reputation for operational excellence in our markets. We have developed a highly-experienced management team, a talented pool of more than 3,500 engineers and a skilled work force that share our core corporate values of quality, professionalism, reliability and efficiency. As a company listed on the Lima Stock Exchange since 1997, we also abide by the highest corporate governance standards in Peru.

Beginning in the mid-1980s, we leveraged our engineering and construction expertise into complementary lines of business, such as the development, ownership, operation and maintenance of infrastructure assets (including the Lima Metro, Peru’s only urban railway system), real estate development, and the provision of technical services primarily to infrastructure-related assets. We believe our business mix creates significant opportunities across our lines of business, generates more stable revenues and earnings on a consolidated basis, and provides additional financial stability to our company.

As a result of our performance in Peru, we have been requested by clients to undertake the engineering and construction of large and complex projects outside our home market, such as the Pueblo Viejo gold mine for Barrick Gold in the Dominican Republic. Through the successful execution of those projects, we have developed operational experience in other Latin American countries. We have further expanded our activities in other key markets of the region through the acquisition of businesses with solid positions in those markets. In February 2011, we acquired a controlling interest in Compañía Americana de Multiservicios (CAM), which is headquartered in Chile and provides technical services to power utility companies in Chile, Peru, Colombia and Brazil. In October 2012, we acquired a controlling interest in Vial y Vives, an engineering and construction company specializing in the Chilean mining sector, thus consolidating our strong position in the Latin American mining E&C sector. We expect to continue to selectively undertake projects and pursue acquisitions and strategic alliances in Latin America to further expand our company outside Peru, with a particular focus on Chile and Colombia.

The tables below show our revenue growth from 2003 to 2009 under Peruvian GAAP and from 2010 to 2012 (upon our conversion to IFRS) under IFRS.

Our Strengths

We believe our company’s strengths provide us with significant competitive advantages. Our principal strengths include the following:

Leader in fast-growing markets

We are the largest engineering and construction company in Peru as measured by revenues during 2012, and the largest publicly-traded engineering and construction company in Latin America as measured by market capitalization as of December 31, 2012. Peru is undergoing a period of unparalleled development, with over 6.5% average annual real GDP growth between 2008 and 2012 and significant private and public investments in the mining, power, oil and gas, transportation, real estate and other infrastructure sectors. We have completed some of the most complex and large-scale infrastructure projects in the country, and we believe we are an integral part of Peru’s ongoing transformation with projects that contribute to the overall economic development

127

of the country. We believe our expertise, reputation, scale and operational capabilities in Peru position us to take advantage of the country’s favorable economic conditions and growth opportunities. We believe we are also a significant infrastructure concessionaire in Peru, the largest apartment building developer in Peru and a leading IT company in Peru.

We believe we are well-positioned to leverage our platform in the Peruvian market to continue to grow our business in other countries in Latin America, primarily Chile and Colombia. Throughout our history, we have undertaken complex E&C projects in the region and have recently completed acquisitions in Chile. Moreover, we believe we are one of the leading mining E&C companies in Latin America.

Long-standing track record and reputation for operational excellence

During our 80-year history, we have focused on the successful and on-time execution of complex projects, through our “deliver before deadline” and “lean construction” initiatives. Our extensive experience has allowed us to gain deep market knowledge and expertise, which help us better serve our clients and manage risks in our contractual arrangements. We believe we have a reputation for operational excellence, and were named among the top ten most admired companies in Peru by PwC in 2012. In addition, KPMG ranked us seventh out of 100 companies with the best reputations in Peru in 2012. We believe that our track record and the reputation we have earned in our markets are key factors in winning new and repeat business, as well as in partnering with strategic industry players and attracting top talent to our company.

Complementary lines of business which generate more stable cash flows and create additional business opportunities across our segments

We have expanded our company by developing complementary lines of business, many of which have become leaders in their respective markets. These lines of business create significant business opportunities across our segments, enabling us to capture a greater share of infrastructure spending, and also generate cost synergies. One example is Norvial, a toll-road concession operated within our Infrastructure segment. In addition to managing the concession, we used our E&C segment to design and construct the expansion of the highway and, once constructed, we are now using our Technical Services segment to operate and maintain the highway. In addition to increasing our levels of consolidated activity, many of these lines of business enable us to achieve more stable cash flows through medium and long-term client service contracts and concessions, which counter in part the cyclicality of the engineering and construction business.

High growth and profitability with strong financial position

Our operations have grown significantly over the last several years, with our consolidated revenues and EBITDA growing at CAGR of 44.6% (34.9% excluding acquisitions) and 18.3% (13.6% excluding acquisitions) from 2010 to 2012, respectively. We have achieved this growth with low levels of indebtedness, relying mainly on cash flow from operations to fund our growth. In 2012, our net debt to EBITDA ratio was 0.1x, and as of March 31, 2013, our net debt amounted to S/.272.4 million (US$105.2 million). In 2012 and the first quarter of 2013, we achieved an EBITDA margin (i.e., EBITDA as a percentage of revenues) of 14.8% and 16.9%, respectively.

Robust backlog and significant additional potential projects

We have a robust backlog which amounted to US$4,165.9 million as of December 31, 2012, 67.0% higher than as of December 31, 2011; and US$4,291.3 million as of March 31, 2013, 3.0% higher than as of December 31, 2012. We believe that our backlog, which as of December 31, 2012 represented approximately 2.2x our related 2012 revenues, provides visibility as to our potential for growth in the coming years, although backlog may not always be an accurate indicator of future revenues. See “Risk Factors—Risk Related to Our Company—Our backlog and our ratio of historical backlog to revenues may not be reliable indicators of future

128

revenues or profit.” Moreover, we believe our backlog is strategically targeted to our key end-markets. Approximately, 79.3% of our backlog as of March 31, 2013 is comprised of contracts with the private sector, strategically targeted to our key end-markets, such as mining, infrastructure, power, energy and real estate. In addition to our backlog, we also have significant potential projects in our pipeline. We have already been awarded concessions for the Via Expresa Javier Prado and Via Expresa Sur expansion projects, for which we are currently in the contract negotiation stage. We are also in the process of obtaining the necessary licenses to begin construction of our large multi-use real estate development project at Cuartel San Martín. Furthermore, we continuously evaluate bidding on contracts arising from the significant ongoing private and public investments in Latin America.

Proven ability to create and grow businesses organically and through acquisitions

We have proven our ability to extend our engineering and construction capabilities into complementary lines of business in a diverse range of industries, some of which began as innovative start-ups in response to client needs. For example, in 1984, we created a new IT business division, which grew and evolved through the years to become the second largest IT company in Peru. Additionally, we also have successfully acquired and integrated new businesses. In February 2011, we acquired a controlling interest in CAM, our electricity services business headquartered in Santiago, Chile, and have integrated its operations and personnel into our company, while improving its operational performance. More recently, in October 2012, we acquired Vial y Vives, an engineering and construction company specializing in the Chilean mining sector which complements our leading E&C practice in the mining sector. We believe that our proven ability to create new businesses, develop businesses organically and acquire and successfully integrate new businesses into our platform is a key competitive advantage as we continue to expand our operations in Latin America.

Highly experienced management, talented engineers and skilled workforce, with shared core corporate values

Our senior management team has an average tenure within our company of approximately 19 years. In 2012, Euromoney recognized us as the second best managed company in the construction and cement sectors in Latin America, and among the five best managed companies in Peru. We motivate our management through performance-based compensation, which align their interests with those of our shareholders. In addition, through our efforts to attract, train and retain our workforce, we have built a talented team of employees, including more than 3,500 engineers. We also have access to a network of approximately 62,000 manual laborers throughout Peru that can supplement our workforce when required by our construction pipeline. Thanks to our extensive and talented team, we have the capability and scale to undertake large and complex projects in Peru and elsewhere.

We have been listed on the Lima Stock Exchange since 1997. We abide by the highest corporate governance standards in Peru, and we are one of only 19 companies in Latin America, and one of only three in Peru, that form part of the Company’s Circle, which recognizes companies for their high corporate governance standards and is sponsored by the International Finance Corporation (IFC), the Organization for Economic Co-operation and Development (OECD) and the Global Corporate Governance Forum. In addition, we have developed a strong corporate culture based on principles of high-quality, professionalism, reliability and efficiency. We employ rigorous safety standards and procedures and emphasize environmental sustainability and social responsibility. In 2012, our engineering and construction subsidiary GyM had an accident incidence rate of 0.29, calculated over 64,202,006 hours worked. In 2011, GyM had an accident incidence rate of 0.52, calculated over 52,979,699 hours worked, which was significantly lower than that of private construction companies in the United States for the year, which had an average of 3.90, as reported by the Bureau of Labor Statistics of the U.S. Department of Labor.

129

Our Strategies

Our vision is to be “the most reliable engineering services company in Latin America.” Our key strategies to achieve this vision include the following:

Be the contractor of choice for large-scale and complex projects in Peru and other key markets

We intend to enhance our position as a contractor of choice for large-scale and complex infrastructure projects in Peru and other key markets, by (i) utilizing the scale, expertise and market knowledge we have accumulated during our 80-year operating history to strengthen and expand our E&C segment; (ii) maintaining and further developing our long-standing client relationships based on our ongoing pursuit of operational excellence; (iii) continuing to strategically partner with global industry leaders, such as Bechtel and Fluor, with complementary capabilities for specific projects that we undertake; and (iv) leveraging our expertise in the mining sector with a view to becoming the premier mining services provider throughout Latin America.

Further expand our infrastructure-related businesses to increase activity across our business segments and generate more stable cash flows

We plan to continue to expand our infrastructure-related businesses to capitalize on private and public investments in Peru, including in toll roads, airports, ports, railroads, hospitals, water utility companies, and other power and oil and gas infrastructure assets. In addition to providing more recurring and predictable cash flows, our Infrastructure segment generates additional business opportunities for our E&C and Technical Services segments.

Maintain highly capitalized balance sheet

We seek to maintain a prudent and sustainable capital structure and a strong financial position to allow us to capitalize on additional business opportunities as they arise. We intend to remain financially disciplined by limiting substantially all our debt incurrence to identified projects with repayment sources.

Selectively pursue international opportunities, focusing on Chile and Colombia

We intend to leverage the capabilities and experience we have in Peru, particularly providing engineering and construction services to the mining, oil and gas and infrastructure end-markets, to continue evaluating and selectively pursuing opportunities in other markets. We expect to focus our efforts primarily on Chile and Colombia, which we believe offer attractive opportunities in these end-markets. We are currently in discussions in connection with potential opportunities in line with our strategy, although we cannot assure you that we will be able to take advantage of these opportunities. We intend to evaluate other international opportunities on a case-by-case basis.

Continue fostering our core corporate values throughout the organization

We will continue to instill our core corporate values throughout our organization, while also transmitting these values to surrounding communities. We will continue to attract and develop our human capital through various training, mentorship and reward programs in order to maintain our position as the best company in Peru to learn and work in the engineering and construction field. We also seek to promote social welfare by fostering relationships with the communities that surround our areas of operation. In 2012, the Inter-American Federation of the Construction Industry recognized us for our corporate strategy and promotion of citizenship with the Latin American Social Responsibility award. We strive to promote our corporate values to strengthen our organization and improve our performance as well as to have a positive impact on the markets where we operate.

130

Engineering and Construction

Our E&C segment has an 80-year track record and is the largest player in Peru as measured by revenues during 2012, according to our estimates based on Peru: The Top 10,000 Companies 2012, undertaking a broad range of activities relating to: engineering; civil construction; electromechanic construction; building construction; and contract mining. We provide E&C services for a diverse range of end-markets, focusing on the mining, power, oil and gas, transportation, real estate and other infrastructure sectors. The following chart sets forth our 2012 revenues by end-market.

2012 E&C Revenues by End-Market

We mainly undertake private-sector projects, particularly projects with a high degree of complexity, which enable us to develop innovative and tailor-made solutions to our clients. We provide our clients with an integral service offering by leveraging our various areas of expertise and engaging in virtually all aspects of project execution, thereby capturing a larger share of investment projects.

In 1999, we began adopting the “lean construction” philosophy as a pillar in our design and construction projects. “Lean construction” aims to create value for customers by better understanding and considering clients’ needs to improve project design, functionality and cost optimization. “Lean construction” also provides techniques and tools that significantly reduce construction waste by improving planning reliability, process design, coordination and collaboration.

Although we primarily undertake engineering and construction projects in Peru, our clients often ask us to undertake the engineering and construction of large and complex projects in other countries such as Mexico, the Dominican Republic, Bolivia, Panama and Chile. As a result, we have developed extensive experience executing projects throughout Latin America. To further capitalize on our capabilities and expertise, we have decided to expand our activities into other key markets, such as Chile and Colombia, which are benefitting from high levels of investment and are aligned with our areas of strategic focus. In 2012 and the first quarter of 2013, approximately US$145.8 million and US$33.7 million of our E&C revenues were derived from international projects outside of Peru.

The acquisition of Vial y Vives has solidified our presence in Chile. While we have been undertaking projects in Chile since 1995, such as the construction of the transmission line and crusher of the Caserones mine for SCM Minera Lumina Copiapo, we believe we will benefit from Vial y Vives’ established and long-lasting presence in the country.

Given the prevalence of mining operations in our principal markets—Peru and Chile together are estimated to have projected investment flows of approximately US$96 billion between 2013 and 2016, according to the Peruvian Ministry of Energy and Mines, Cochilco, and APOYO Consultoria—we have significant expertise with

131

respect to specialized engineering and construction services for the mining sector. As a result, we believe we are one of the leading mining construction companies in Latin America and we leverage this expertise both within our principal markets as well as to selectively undertake complex projects across the region.

Clients

We believe we have developed long-term relationships with many clients as a result of our performance over the years and are focused on the successful and on-time execution of complex projects, through our “deliver before deadline” and “lean construction” initiatives. Our extensive experience has earned us a reputation for operational excellence and allowed us to gain deep market knowledge and expertise, which help us better serve our clients. The principal clients of our E&C segment include renowned domestic and multinational mining, power, oil and gas, transportation and infrastructure development companies, such as Xstrata, Hochschild, Buenaventura, Luz del Sur, Kallpa, Transelec, Cementos Lima, Rio Alto, Chinalco Mining, Minera Lumina Copiapo, Hudbay Minerals, among others. We have a well-diversified client base as none of our engineering and construction clients accounted for 15% or more of our consolidated revenues in 2012.

Project Selection and Bidding

We win new engineering and construction contracts through public bidding processes or direct negotiation, from a variety of sources, including potential client requests, proposals from existing or former clients, opportunities sought by our commercial team and from requests by the Peruvian government. More than 80% of our 2012 revenues came from private-sector projects. The Peruvian government and its agencies typically award construction contracts through a public bidding process conducted in accordance with the Peruvian State Contracting Law (Ley de Contrataciones del Estado). In the private sector, in addition to obtaining new projects,

135

another important source of revenue involves increases in the scope of work to be performed in connection with already existing projects. These arrangements are typically negotiated directly with the client, often during the course of the work we are already performing for that client.

We have a designated team that oversees the management of project proposals and a commercial team that reviews and evaluates potential projects in order to estimate costs. In considering whether to bid for a potential project, we principally consider the following factors: competition and the probability of being awarded the project; project size; the client; our experience undertaking similar projects; and the availability of resources, including human resources. As part of the project selection process, our commercial team performs a detailed cost analysis utilizing sophisticated software we developed to assist in determining whether the project is viable and cost-effective. If we choose to pursue a project, a budget leader is assigned to prepare the offer that is eventually presented to our potential client.

Despite the budgeting risks generally associated with engineering and construction contracts, our management believes that our experience generally allows us to estimate our project costs accurately. Our project management teams also periodically review project budgets for inconsistencies between budgeted and actual costs in order to recover for cost variations through contract renegotiation. Budgeting risks are also mitigated through advance payments. Considering that we receive advance payments for most of our E&C contracts, our E&C projects typically do not require significant working capital investment. Our E&C segment secures financing primarily to purchase machinery and equipment for our construction and contract mining services.

We are required, in the majority of our construction contracts, to provide a performance bond to guarantee project performance and completion, which remain in effect for the contract’s duration. We are also required to provide performance bonds to secure any advance payments provided to us by our clients. These bonds are periodically reduced during the project’s execution in accordance with project advancement. After the expiration of the contract term, we are typically required to provide an additional performance bond that remains valid for one year.

Contracts

We principally enter into four types of engineering and construction contracts:

• Cost-plus fee contracts. The contract price is based upon actual costs incurred for time and materials plus a fee, which may be a percentage of the costs incurred or a pre-determined fee. Sometimes, cost-plus fee contracts include a target price, and a contractual arrangement that determines our responsibility in the event the total cost of the project exceeds the target price or the benefit we receive if the total contract price results in cost savings. Cost-plus fee contracts tend to involve the least budgeting risk for us.

• Unit price contracts. The contract price is based upon a price per unit (i.e., variable quantities of work priced at defined unit rates). Each line item of the project budget, such as cubic meter of earth excavated or cubic meter of concrete poured, has a defined price, but the quantities of the units may vary. Our bid price reflects our estimate of the costs that we expect to incur for each work unit. These contracts typically include an “escalation” clause which is essentially an adjustment mechanism to account for Peruvian inflation.

• Lump-sum contracts. The contract price is fixed. Our bid is meant to cover all costs and include a profit. The principal risk in these types of contracts are errors in calculating our costs, including those of raw materials; miscalculation of the number of units or workers needed to complete the project; unanticipated technical complexities; or other unexpected events or circumstances that may increase our costs.

• Engineering, procurement and construction (EPC) contracts. EPC contracts, known as “single source” or “turn-key” contracts, are also lump-sum contracts. Pursuant to EPC contracts, we provide a broad range of basic and detailed engineering services, including preparation of the technical project

136

specifications, detailed drawings and construction specifications; technical studies; and identification of lists of materials and equipment necessary for the project. These contracts, which we utilize predominantly for our mining contracts, require a high-level of expertise and generally involve the most budgetary risks for us.

For further information, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations.”

Raw Materials

The principal inputs we use in our E&C segment are, among others, fuel, cement and steel. These and the other products we require in our E&C segment may be subject to the availability of raw materials, such as oil and iron, and commodity pricing fluctuations, which we monitor on a regular basis. We typically aim to enter into master supply agreements for a period of six months to one year. Although we obtain the majority of our inputs needs in Peru, we believe we have access to numerous global supply sources. The availability of these inputs, however, may vary significantly from year to year due to various factors including client demand, producer capacity, market conditions, transport costs and specific material shortages, and we may incur additional costs in obtaining them.

We purchase and lease the equipment we require for our E&C segment business from several local and international suppliers, currently with no significant concentration with any particular suppliers. While we do not have difficulty obtaining the equipment we need, we may face difficulties finding skilled personnel who are able to operate certain equipment and machinery.

Competition

We generally compete with some of the largest contractors in Peru and the other countries where we operate. Because the E&C sector is highly competitive, the markets served by our business generally require substantial resources and highly-skilled and experienced technical personnel. The principal competitors of our E&C segment include Besalco S.A., Odebrecht S.A., Andrade Gutierrez S.A., Obrascón Huarte Lain S.A., JJC Contratistas Generales S.A., Cosapi S.A., Techint SAC, SSK Montajes e Instalaciones S.A.C., Skanska del Perú S.A., Mota-Engil Peru S.A., Grupo San Jose, Salfacorp S.A., Constructores Interamericanos S.A.C. (COINSA), and San Martín Contratistas Generales. For certain projects, due to the size of the project, expertise required and other factors, we may choose to partner with our competitors, including the aforementioned companies.

Competition for our E&C segment is driven by performance, skill and project execution capabilities for completing complex projects in a safe, timely and cost-efficient manner, as well as price.

Infrastructure

We are an important toll road concessionaire in Peru, operating three toll roads. Moreover, we are the concessionaire for the Lima Metro, the largest mass-transit rail system in Peru, and a waste water treatment plant. Additionally, we operate multiple fuel storage facilities, two producing oil fields under long-term government contracts and a gas processing plant

Backlog is calculated as of the last day of the applicable year. Revenues are calculated for such year and converted into U.S. dollars based on the exchange rate published by the SBS on December 31 of the corresponding year. Includes revenues only for businesses included in backlog. Our ratio of backlog to revenues for our Infrastructure segment is not representative of what we would expect the ratio to be in future periods because in 2010 and 2011 we did not have revenues for La Chira waste water treatment plant and the Lima Metro and in 2012, the first quarter of 2012 and the first quarter of 2013 we only had pre-operation revenues for La Chira waste water treatment plant and revenues for the Lima Metro based on a limited number of trains during the first year of operation.

Our strategy is to pursue concessions with the potential to generate business opportunities across our organization. Once we obtain a concession, our goal is to be involved virtually in all aspects of project execution through the participation of our different business segments, from the design and construction to the operation and maintenance of the infrastructure asset.

Through our Infrastructure segment we participate in a number of joint operations with the objective of bidding for government concessions or other long-term contracts. When bidding, we occasionally look for partners to reduce our risks and achieve the level of expertise needed to meet the demands of each particular project.

Principal Infrastructure Lines of Business

Toll Roads

Peru’s economic development is underpinned by a strong government commitment to infrastructure investment, with a particular focus on improving the country’s road system through the award of new concessions to the private sector. As of January 2013, the total transportation project pipeline in Peru was US$22 billion, according to APOYO Consultoría. We believe this investment offers significant opportunities to our Infrastructure segment.

Our Infrastructure segment currently has three toll road concessions through our subsidiaries Norvial, Survial and Canchaque. All three toll roads are currently in operation and we have the authorizations, permits and licenses necessary to fulfill our obligations under each concession, including releases of rights of way. All of our toll road concessions have utilized the construction services of our E&C segment and the roads are currently operated and maintained by our Technical Services segment. The table below sets forth selected financial information relating to our toll roads.

The pie charts below set forth the breakdown of our revenues and EBITDA from our toll road concessions for 2012.

Revenues	EBITDA

Norvial

Under our Norvial concession, we operate and maintain part of the only major highway that connects Lima to the northwest of Peru. This 183-km road, known as Red Vial 5, runs from the cities of Ancón to Pativilca and has three toll stations. The concession was awarded to Norvial in 2003 for a 25-year term. We own 50.1% of Norvial; and our partners in this concession are JJC Contratistas Generales and Besco. The following map shows the location of the Red Vial 5 road in Peru.

140

Norvial’s revenue derives from the collection of tolls. For the Norvial toll road, the toll rate is set out in the Norvial concession agreement and adjusted in accordance with a contractual formula that takes into account the nuevo sol/U.S. dollar exchange rate and Peruvian and U.S. inflation. We are required to transfer 5.5% of our monthly toll revenue to the Peruvian Ministry of Transport and Communications and pay a 1% regulatory fee to the Peruvian Supervisory Agency for Investment in Public Transportation Infrastructure.

Our obligations under the concession include expanding the already existing road by, among other things, adding two additional lanes. The first stage of construction was completed in 2008 and the second stage is expected to begin between 2014 and 2015. We estimate that our capital investment for the second stage will be approximately US$100 million. When the construction of the second stage begins, we will also be required to pay a one-time estimated fee of approximately US$1.8 million to the Peruvian Supervisory Agency for Investment in Public Transportation Infrastructure.

Unlike other toll roads in Peru, Norvial charges toll fees in both directions. Our road is highly transited both by heavy vehicles, primarily for the purpose of transporting goods, and also by passenger vehicles, which typically use the road to access tourist destinations. The following table sets forth average daily traffic volume and average toll fees charged for vehicle equivalents in respect to the Norvial toll road concession for 2010, 2011 and 2012.

	Year ended December 31,						Three months ended March 31,
	2010		2011		2012		2012		2013
Average daily traffic by vehicle equivalents(1)		14,641		16,290		17,799		17,667		19,577
Average toll fee charged for vehicle equivalents (in S/.)		13.28		13.23		13.15		12.93		12.63

(1) Each automobile is counted as one equivalent vehicle and commercial vehicles (such as trucks or buses) represent the number of equivalent vehicles equal to the ratio between the toll rate applicable to commercial vehicles and that which is applicable to one automobile.

Survial

Under our Survial concession, we operate and maintain a 750 km road from the San Juan de Marcona port to Urcos, Peru, which is connected to an interoceanic road that runs up to the Peruvian-Brazilian border. The road has five toll stations and three weigh stations. The concession was awarded to Survial in 2007 for a 25-year term. We own 99.9% of Survial. The following map shows the location of the road in Peru.

Our obligations under the concession include the construction of the road, which was completed in 2010.

Our revenue from this concession consists of an annual fee paid to Survial by the Peruvian Ministry of Transport and Communications in consideration for the operation and maintenance of the road, which fee can vary depending on the amount of maintenance required due to road damages. In 2010, 2011, 2012 and the first quarter of 2013, the fee amounted to US$7.4 million, US$9.1 million, US$37.5 million and US$4.3 million, respectively. Our revenue in this concession does not depend on traffic volume.

Canchaque

Under our Canchaque concession, we operate and maintain a 78 km road from the towns of Buenos Aires to Canchaque, in Peru. The road has one toll station. The concession was awarded to Canchaque in 2006 for a 15-year term. We own 99.9% of Canchaque. Our obligations under the concession include the construction of the road, which was completed in 2009. Our revenue from this concession consists of an annual fee paid by the Peruvian Ministry of Transport and Communications in consideration for the operation and maintenance of the road, which fee can vary depending on the amount of road maintenance required due to road wear and tear. In 2010, 2011, 2012 and the first quarter of 2013, the fee amounted to US$0.9 million, US$1.5 million, US$1.7 million and US$2.5 million, respectively. Our revenue in this concession does not depend on traffic volume.

Additional Toll Road Projects

We continuously evaluate infrastructure projects and strategically present public-private partnership proposals and participate in bidding processes for road concessions. In 2012, we were awarded, and are currently negotiating the terms for, a 40-year concession for a 4.6 km extension of Via Expresa Sur, one of the main roads

142

in Lima, which crosses the city from north to south. The road will connect downtown Lima to Panamericana Sur, a highway that runs from Ecuador to Chile. Our estimate of the total investment under the concession, as submitted in our bid, is of approximately US$200 million. Such investment will be made during the construction phase, which is expected to take up to five years. Our revenue will derive from the collection of a toll fee upon completion of the construction. The concession is expected to guarantee a minimum annual revenue of US$18 million during the first two years of the concession term and US$19.6 million for the third year and for an additional period, the term of which is being negotiated. If in a particular year, our annual revenue is lower than the minimum guaranteed, we expect the government to compensate us for the difference, up to an amount not to exceed US$10 million. Completion of the project is subject to expropriation of the land necessary for the construction of the road. Releases of right of way are still pending.

A joint operation in which we have a 50% interest has been awarded, and is in the process of negotiating the terms for, a 37-year concession for Via Expresa Javier Prado, a 20 km toll road that crosses Lima from east to west, traversing through eight districts. According to estimates from the Municipality of Lima, the total investment in the concession is expected to amount to approximately US$790 million. Such investment will be made during the construction phase which is expected to take between five to seven years. Our revenue will derive from the collection of a toll fee upon completion of the construction. This concession was awarded to the joint operation at the end of the 1990s and negotiations were discontinued but were recently resumed in 2012.

We cannot assure you if or when the concession contracts will be agreed or whether the contractual terms will be favorable to us. See “Risk Factors—Risks Related to our Infrastructure Business.”

Mass Transit

In 2011, we were awarded a 30-year concession for the operation of Line One of the Lima Metro, Peru’s only urban railway system. The concession was awarded to our subsidiary GyM Ferrovías, in which we hold a 75% ownership interest, with the other 25% being held by Ferrovías S.A.C. Our obligations under the contract include: (i) the operation and maintenance of the five existing trains provided by the government; (ii) the acquisition of 19 new trains on behalf of the Peruvian government, which will be the legal owner of such trains; (iii) the operation and maintenance of the 19 new trains (24 trains in the aggregate); and (iv) the design and construction of the railway maintenance and repair yard, which is being built by our E&C segment.

143

The operation and maintenance of the trains is carried out by our Technical Services segment, which is currently operating the first stretch of Line One and will start operating the full Line One once the construction of the second stretch, currently planned for the third quarter of 2014, is complete. A joint operation in which our E&C segment participates was awarded the construction of the second stretch of Line One. The map below shows the route of Line One.

We expect to make a total of S/.830 million (US$320.6 million) in capital expenditures in connection with the acquisition of the new trains on behalf of the government and the construction of the maintenance and repair yard. As of March 31, 2013, we had spent S/.410.8 million (US$158.7 million) of this amount. We have ordered the 19 new trains and have received eleven of them as of the date of this prospectus. We are awaiting approval from the Ministry of Transport and Communications to begin operating these new trains. We expect to receive the remaining trains on a periodic basis and expect to have all 24 trains in operation by the third quarter of 2014.

Our revenue from this concession consists of a quarterly fee that we receive from the Ministry of Transport and Communications based on the kilometers travelled per train and adjusted for inflation, with the fee per kilometer, the number of trains required to be in operation and the number of kilometers that we are required to travel established by the terms of the concession. Our revenues do not depend on passenger traffic volume. According to the government, completion of the second stretch should take place by the third quarter of 2014. This, together with the operation of the new trains, will increase our revenue since we will operate more trains which will travel more kilometers, as established in the concession contract.

144

We currently operate five trains on the first stretch which enable us to travel 812,539 km per year based on required schedule and frequency. We expect to gradually place trains in operation and, by the third quarter of 2014, we expect to be in full operation with 24 trains that are expected to travel 2,603,453 km per year in the full Line One, based on required schedule and frequency. The following tables show (i) the length of Line One, the average frequency of the trains and the fee per kilometer travelled; and (ii) the increase in scheduled kilometers in relation to the number of trains in operation.

145

Pursuant to the concession, we must comply with certain requirements in the operation of the trains. According to the concession, at least 95% of our trains must be running and available for use and not less than 85% of our trains that are available for use must arrive to destination on scheduled time. The table below shows our monthly average results during 2012 and the first quarter of 2013.

Water Treatment

In 2012, we were awarded a 25-year concession for the construction, operation and maintenance of La Chira waste water treatment plant in the south of Lima. The project is aimed at addressing Lima’s environmental problems caused by sewage discharged directly into the sea. We hold a 50% share in this project and our partner Acciona Agua holds the remaining 50%.

We estimate that La Chira’s total investment in the concession will amount to approximately US$83.1 million. Once the project is completed, La Chira will be entitled to collect (i) an annual payment for the investment made in the construction of the project for an amount of S/.24.2 million (approximately US$9.3 million), and (ii) and annual payment for the operation and maintenance of the project for an amount of S/.6.8

146

million. These fees will be paid by Sedapal S.A., the public utility company responsible for the supervision of the water service in Lima, for a period of 25 years. We funded our construction costs related to La Chira through the sale of government certificates to financial institutions, and, as a result, will not receive future cashflows from item (i). See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Our Results of Operations—Infrastructure.” A joint operation in which our E&C segment participates is undertaking the construction of the waste water treatment plant.

Energy

We currently operate three energy businesses within our Infrastructure segment. We have two long-term hydrocarbon extraction service contracts with Perupetro, the Peruvian entity responsible for the administration and supervision of all exploration and production contracts in Peru, under which we operate two onshore oil producing fields in northern Peru. Aggregate average production of these fields in 2012 was of approximately 1,400 bbl per day. We also own and operate a gas processing plant which processes and fractions natural gas from its liquids in northern Peru and delivers dry gas to a gas-fired power generation company under a long-term processing and fractionation agreement. In addition, we are a 50% partner in Consorcio Terminales which has a contract with Petroperú, the other state owned oil and gas company, to operate nine fuel storage terminals, which we believe handled approximately one-third of the country’s refined fuel in 2012.

Oil and Gas Production

We operate and extract oil from two fields (Block I and Block V) located in the province of Talara in northern Peru. Both fields are operated under long-term service contracts in which we provide hydrocarbon extraction services to Perupetro. Hydrocarbons extracted from each field belong to Perupetro, which in turn pays us a variable fee per barrel of lifted hydrocarbons, which fee is based on a basket of international crude prices and the level of production. The fee is paid on a monthly basis. Our activities are focused on proved reserves development and production and are conducted in mature oil fields, which have been producing oil for over 100 years in the case of Block I and over 50 years in the case of Block V. We believe our activities in these fields bear limited exploration risk.

The following table shows selected information about our fields.

Property	Basin	GMP’s Ownership			Expiration	Developed Acres		Undeveloped Acres
Block I	Talara		100	%	2021		25,154		4,808
Block V	Talara		100	%	2023		6,320		2,496

Block I:

We operate and extract oil and natural gas from Block I under a 20-year hydrocarbon extraction service contract with Perupetro, which was extended for an additional 10-year term and expires in December 2021. Average daily production during 2012 was 1,253 barrels of crude oil. We operate 158 wells using various oil extraction systems and operate a network of production batteries and pipelines to collect, measure and deliver oil in fiscalization point close to the Talara refinery. The field is located in the province of Talara, department of Piura, in northern Peru, approximately five miles from the Talara refinery, the second largest refinery in the country. Block I is the oldest oil producing field in Peru and has been producing oil since around 1890.

Block V:

We operate and extract oil and natural gas from Block V under a 20-year hydrocarbon extraction service contract with Perupetro, which was extended for an additional 10-year term and expires in October 2023. Average daily production during 2012 in this field was 150 barrels of crude oil. We operate 41 wells in this field using various oil extraction systems. The Block V field is located in the province of Los Organos, department of Piura, Peru, close to the border with Ecuador. Block V has been producing oil since the 1950s.

148

The map below shows the geographic location of our oil producing blocks in northern Peru.

Under our hydrocarbon extraction service contracts, we are entitled to a variable fee, which is based on the level of production of each field and a basket of international crude prices, which include Fortis Blend, Suez Blend and Oman crudes. During 2010, 2011 and 2012, we received an average fee of US$61.08, US$84.00 and US$86.13 per barrel of extracted oil, which was equivalent to approximately 76.8%, 75.5% and 77.1%, respectively, of average Brent crude prices in the same years. During the first quarter of 2013, we received an average fee of US$87.19 per barrel of extracted oil, which was equivalent to approximately 77.5% of average Brent crude prices in the quarter. According to our hydrocarbons development contracts, we are required to deliver all the oil and gas we produce, regardless of its quantity, to Perupetro. Therefore, we are not committed to provide a fixed and determinable quantity of oil or gas in the near future under existing contracts.

We produce natural gas as a byproduct of the production of crude oil. In Block I, we provide natural gas to Perupetro, which in turn sells it to EEPSA, and pays us a fee which varies depending on market conditions. In Block V, we reinject that natural gas produced into the wells. Our revenues for the sale of natural gas are not material relative to our oil production revenues.

149

Estimated Proved Reserves:

The following table sets forth estimated proved crude oil and natural gas reserves in Blocks I and V as of December 31, 2012. We have only included estimates of proved and have not included any estimates of probable and possible reserves.

	Crude Oil (Mbbl)		Natural Gas (MMcf)		Crude Oil Equivalents (MBoe)
Block I:
Proved developed producing		2,112.5		9,374.3		3,769.3
Proved developed non-producing		260.8		716.4		387.4
Proved undeveloped		1,197.3		9,825.0		2,933.7
Total proved reserves		3,570.6		19,915.6		7,090.4

Proved developed producing		388.7		—		388.7
Proved developed non-producing		0.0		—		—
Proved undeveloped		52.0		—		52.0
Total proved reserves		440.7		—		440.7
Total:
Proved developed producing		2,501.2		9,374.3		4,158.0
Proved developed non-producing		260.8		716.4		387.4
Proved undeveloped		1,249.3		9,825.0		2,985.7
Total proved reserves		4,011.2		19,915.7		7,531.1

Proved reserves are those quantities of oil and natural gas which, by analysis of geosciences and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations. The term “reasonable certainty” implies a high degree of confidence that the quantities of oil and/or natural gas actually recovered will equal or exceed the estimate. To achieve reasonable certainty, NSAI employed methodologies that have been demonstrated to yield results with consistency and repeatability. The methodologies and economic data used in the estimation of the proved reserves in the fields include, but are not limited to, well logs, geologic maps and available down hole and production data, seismic data, and well test data.

Reserve amounts were determined based on the 12-month unweighted arithmetic average of the first-day-of-the-month Brent crude price for each month in the period January through December 2012, which, pursuant to our contractual agreements, resulted in oil and gas prices of US$87.25 per barrel and US$1.29 per Mcf, respectively, that for the purpose of reserve amount estimation were assumed to remain constant throughout the remaining terms of our service contracts.

Proved undeveloped reserves in the fields as of December 31, 2012 were 2,985.7 Mboe, consisting of 1,249.3 Mbbl of crude oil and 9,825.0 MMcf of natural gas. We estimate that during 2012 approximately 1,044.35 Mboe (635.5 Mbbl of crude oil and 2,313.4 MMcf, or 408.85 Mboe, of natural gas) of proved undeveloped reserves were converted into proved developed reserves. We estimate that during 2012, proved undeveloped reserves declined by 3.37%, or 104.05 Mboe, consisting of a decline of 183.58 Mbbl of crude oil and an increase of 79.53 Mboe (450 MMcf) of natural gas. Capital expenditures, for both drilling activities and workovers, made during 2012 and the first quarter of 2013 to convert undeveloped reserves to proved developed reserves amounted to approximately US$19.8 million and US$3.9 million, respectively.

150

The principal changes in proved undeveloped reserves during 2012 were:

• Crude oil reserves: proved undeveloped crude oil reserves decreased 183.58 Mbbl during 2012, due to the elimination of four drilling locations in Block V, the effect of which was partially offset by six new drilling locations in Block I, in each case as a result of geological and engineering studies conducted throughout the year; and

• Natural gas reserves: proved undeveloped natural gas reserves increased 79.53 Mboe (450 MMcf) during 2012 as a result of the higher natural gas/crude oil relationship found in the wells drilled over the last years.

For changes in proved developed and undeveloped reserves from December 31, 2009 to December 31, 2012, see supplementary data (unaudited) annexed to our audited annual consolidated financial statements included in this prospectus.

Qualifications of Technical Persons and Internal Controls Over Reserves Estimation Process

The reserves estimates shown in this prospectus have been independently prepared by Netherland, Sewell & Associates, Inc., independent petroleum engineers, in a report dated May 28, 2013, which was prepared in accordance with the definitions and guidelines of the SEC.

Production, Revenues, Prices and Costs:

The following table sets forth information regarding our production, revenues, prices and production costs for 2010, 2011, 2012 and the first quarter of 2013.

	Year ended December 31,						Three months ended March 31,
	2010		2011		2012		2013

General and administrative expenses (US$/boe)		4.5		4.7		5.2		4.0
Depreciation, depletion, amortization and accretion expenses (US$/boe)		4.5		8.4		13.9		15.2

(1) Hydrocarbons extracted from our fields belong to Perupetro, which in turns pays us a per barrel fee for lifted hydrocarbons.

(2) Crude oil sales volume differs from total production volume due to operational circumstances such as the inventory of product stored in our field batteries at the end of each monthly measurement. “Average sales prices” refers to the fees received in consideration for our extraction services, which do not equal the sales prices of crude oil. Average sales prices have been calculated using a basket price formula according to the service contracts of each block. Such formulation is at a discount to global oil prices and we do not otherwise pay royalties on the oil and gas extracted. Per unit costs have been calculated using sales volumes.

Acreage, Productive and Development Wells, Drilling:

The following table sets forth certain information regarding the total developed and undeveloped acreage as of March 31, 2013.

Formation	Developed Acreage		Undeveloped Acreage
Block I
Pariñas		2,271		70
Mogollón		2,420		450

Total Block V		2,045		890
Total		9,858		3,315

As of March 31, 2013, we had a total of 233 producing wells. Our wells are oil wells, many of which also produce natural gas. We do not have interests in wells that only produce natural gas.

The following table shows the number of development and exploratory wells drilled during 2010, 2011, 2012 and the first quarter of 2013 in both Block I and Block V.

	Year ended December 31,						Three months ended March  31,

Total		—		1		—		—

During 2010, 2011 and 2012 we invested US$9.4 million, US$14.2 million and US$18.7 million, respectively, in drilling activities. During the first quarter of 2013, we invested approximately US$3.7 million in drilling activities. Eleven of the twelve development wells drilled during 2012 were located in Block I with a depth average of approximately 8,300 feet. All of them are productive wells and they partially explain our production volume increase registered during 2012 compared to 2011. In 2011 we drilled one exploratory well and the results of the exploratory formations on target was not productive. However, the well still has production in its shallow formations.

The company continues to drill an average of 1.1 wells per month in its quest to accelerate the recovery of proved reserves. Most of the drilling is done in Block I where environmental permits allow us to drill up to 121 new wells. From time to time, based on geological analysis, we try to obtain more oil by increasing the depth of our productive formations. In this way, we minimize exploratory risks.

153

Under the terms of our service contracts, at the time the contract terminates, we are required to close non-producing wells that we have drilled. As of December 31, 2012, we estimated that we will be required to close 70 wells in Block I in December 2021 and 15 wells in Block V in October 2023, out of approximately 400 wells currently not in production. We have created a provision in our financial statements for the costs relating to those well closings. See note 19 to our audited annual consolidated financial statements included in this prospectus.

Gas Processing Plant

We own a gas processing plant located 7 km north of the city of Talara in Piura, Peru. We currently have under a long-term delivery and gas processing and fractioning contract with EEPSA, according to which EEPSA delivers wet natural gas that it purchases from onshore and offshore gas operators in the area. We then process and fraction the gas into two products: (i) dry natural gas, which can be used as fuel in EEPSA’s gas-fired turbine; and (ii) natural gas liquids, which are sold in the Peruvian market. Under the terms of the agreement, we are responsible for all operating costs of the gas processing plant but are also entitled to keep revenues from the sale of the natural gas liquids to third parties after payment of a variable royalty, based on the volume of gas processed, to EEPSA. Our current gas processing and fractionation contract with EEPSA expires in 2023.

Our gas processing plant has the capacity to process up to 44 MMcf per day. We processed 29.7 MMcf per day during 2010, 31.4 MMcf per day during 2011 and 26.3 MMcf per day during 2012. Volumes processed by our gas processing plant ultimately depend upon gas volumes demanded by EEPSA for its gas-fired turbines. These volumes vary per month and depend upon the power dispatch curve of EEPSA among Peruvian power generation plants. In rainy months (December to April) where hydroelectric power generation in Peru is typically higher, gas volumes demanded by EEPSA are lower than in dryer months (May to November) in which activity of thermal generators tends to be higher.

154

Fuel Storage Terminals

We are a 50% partner in Consorcio Terminales and have a contract with Petroperú to operate the largest fuel storage terminal business in Peru. Our 50% partner is a Peruvian affiliate of Oiltanking GmbH, one of the world’s largest operators of independent terminals for bulk liquid storage. Our open-access terminals are equipped with modern technologies and offer our customers dependable and critical handling and storage services for refined petroleum liquid products, maintaining high quality, safety and environmental standards. We have seven terminals strategically located along Peru’s Pacific coast. We also have two inland facilities. We provide storage, handling and loading and uploading services for a broad range of refined petroleum liquid products, including gasoline, aircraft fuel, diesel and heavy fuel oil. We deliver the liquids into two types of transportation systems, railroad cars and cistern trucks. Because of the strategic location of our assets, our deep-water access, inland terminals and our aggregate storage capacity of 2.6 MMbbl, we believe that we are well-positioned to cover the needs of our clients, the two principal refineries in Peru. The map below shows the location of each of our fuel storage terminals in Peru.

Our activities under Consorcio Terminales are carried out under a 15-year contract, which we entered into in January 1998 and which has been extended until August 2014. We cannot assure you that the current contract will be renewed or that the terms of such potential renewal will not differ materially from those of our current contract.

Under the current contract, Consorcio Terminales receives revenues paid in connection with monthly reserved volume in tanks for refined crude products (storage fee) and for volumes loaded and delivered into railroad cars or cistern trucks to each terminal (throughput fee). The storage fee per barrel, is based upon reserved volumes whether they are received or not. The throughput fee is paid based on effective barrels delivered per month. During 2010, 2011, 2012 and the first quarter of 2013, Consorcio Terminales generated revenues of US$40.3 million, US$44.2 million, US$49.1 million and US$11.7 million (we are entitled to 50% of the joint operation revenues), respectively. Under the contract, Consorcio Terminales is responsible for paying the fuel terminals operating costs and also paying a royalty fee to Petroperú based on effective barrels delivered each month.

155

At the current stage of the contract, any capital expenditure we invest in the fuel storage terminals can be recouped from any present and future royalties we owe to Petroperú.

Other Terminal Operations

We are a 50% partner in Terminal Marino Pisco Camisea and have a contract with Pluspetrol to operate an export terminal for gasoline, diesel, propane and butane. In 2012, this terminal dispatched 127 ships 2.8 million tonnes of natural gas liquids. We are also a 25% partner in Terminal de Químicos de Matarani, which in 2012 dispatched 34,930 tonnes of sodium hydrosulfide for international mining companies. During 2010, 2011, 2012 and the first quarter of 2013, these activities generated revenues in the aggregate of approximately US$3.6 million, US$4.1 million, US$4.3 million and US$1.2 million, respectively.

Competition

Our ability to grow through successful bids for new infrastructure concessions or other long-term contracts could be affected as a result of competition. We view our competition as including both Peruvian and international infrastructure concession operators including joint operations with partners with specialized expertise in the relevant sector. Competition varies on a case-by-case basis, depending on the main purpose of the concession.

Real Estate

Our Real Estate segment is the largest apartment building developer in Peru, in terms of number of units sold and value of sales in 2012, according to Tinsa, and is focused on the development and sale of affordable housing and housing as well as other real estate projects. Since commencing our operations in 1987, we have developed approximately 450,000 m² of affordable housing (approximately 6,614 units); approximately 290,000 m² of housing (approximately 1,400 units); approximately 115,000 m² of office space (approximately 780 offices); and approximately 43,000 m² of shopping centers (three shopping centers). Moreover, we are currently building approximately 160,000 m² of affordable housing (approximately 2,520 units); approximately 22,000 m² of housing (approximately 160 units); and approximately 24,000 m² of office space (approximately 40 offices, with an average size of 600 m² each). Our Real Estate segment also owns significant land parcels in Lima, comprising of approximately 888 hectares as of March 31, 2013, and we have sold undeveloped land in the past and intend to continue such sales in the future.

We undertake a significant amount of the activities in our Real Estate segment with partners through financing and commercial arrangements we use to purchase land and to develop real estate projects. See “—Financing.” As a result, a significant amount of our net profit in the Real Estate segment is attributable to the non-controlling interest of our partners. See also “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—General—Real Estate.”

Principal Real Estate Activities

Our real estate developments include the following products:

• affordable housing;

• housing; and

• commercial real estate.

We began developing affordable housing projects in 2001, following the Peruvian government’s efforts to address the country’s housing deficit, particularly for low-income families. We launched the first major affordable housing project in Peru in 2007, Parque Agustino in Lima’s El Agustino neighborhood. Since 2001, we have completed 11 affordable housing projects. As of December 31, 2012, we are developing 11 affordable housing projects, which are in various stages of development, including six which are in the construction phase and five for which we have purchased land, but are still in the process of obtaining the required approvals and permits. Two of our ongoing affordable housing projects consist of expansions of projects previously completed by us.

Affordable housing consists of apartments, usually ranging between 55 and 110 m², that are purchased through government subsidies. The Peruvian government has adopted the Nuevo Crédito MiVivienda and Techo Propio programs, among others, which promote access to affordable housing in Peru by providing government subsidies to individuals for the purchase of homes. In order for a unit to qualify for the Nuevo Crédito MiVivienda program, its selling price must range between 14 UIT and 70 UIT (approximately between S/.52,000 and S/.259,000). In order for a unit to qualify for the Techo Propio program, its selling price must range between 5.5 UIT and 14 UIT (approximately between S/.20,000 and S/.52,000).

In order to be eligible for an affordable housing subsidy under the Nuevo Crédito MiVivienda program, a purchaser must not own any other home or have benefitted from a housing subsidy program in the past, among other requirements. A purchaser must also provide a down payment between 10% and 30% of the total purchase amount. Housing subsidies under this program fluctuate between S/.5,000 and S/.12,500, which incentivize purchasers with reduced monthly rates so long as they pay their mortgage loan payments on a timely basis. In order to be eligible for an affordable housing subsidy under the Techo Propio program, a purchaser must have a monthly income that does not exceed 0.45 UIT (approximately S/.1,665) and must not have received any other government-sponsored housing benefit in the past, among other requirements. A Techo Propio purchaser must also show proven savings equal to at least 10% of the total purchase amount. Housing subsidies under this program fluctuate between three UIT and five UIT (approximately between S/.11,100 and S/.18,500). Purchasers of subsidized housing under both programs are also not required to pay a value-added tax normally applicable to residential purchases.

We develop substantially all of our affordable housing projects on land purchased from the private sector. To the extent these projects meet the requirements of a particular government subsidy program, purchasers can purchase units with government subsidies. Some of our affordable housing projects, however, such as Parque Agustino, are developed through government bidding processes. Government subsidy programs like Nuevo Crédito MiVivienda and Techo Propio have driven the demand for affordable housing in Peru, which has in turn increased our sales of affordable housing units.

Our housing developments consist of residential buildings comprised of apartments with a mid- to high-price range that do not qualify for government subsidies. Since 1987, we have developed 36 housing

157

developments. As of December 31, 2012, we are developing five housing projects, including four which are in the construction stage and one for which we have purchased land, but are still in the process of obtaining the required approvals and permits. Our housing units typically range between 130 and 400 m² in size.

Substantially all of our affordable housing and housing development projects are located in Lima. We have also purchased land to develop two affordable housing projects in Piura and Chimbote, two cities north of Lima. We intend to develop affordable housing projects in other cities outside of Lima.

(1) We typically pre-sell our affordable housing and housing units before construction begins and continue to sell during construction, although we recognize revenues at the time of delivery of units.

We develop and sell office and commercial buildings, such as shopping centers. On certain occasions, we have operated our commercial real estate and later sold it, such as Larcomar, a landmark shopping center which we built in 1998 and sold in 2010. We have also developed commercial real estate buildings in connection with our affordable housing and housing projects, such as the Parque Agustino shopping center. Since 1987, we have developed 11 office buildings, three shopping centers and one medical center. We are currently in the process of developing five office buildings in Lima, two of which are in the construction phase, including the Real Ocho project, a 16-floor office building (30% of which is owned by us and 70% of which is owned by Inversiones Centenario S.A.A.); and three for which we have purchased land, but are still in the process of obtaining the requires approvals and permits.

158

Land Bank

We typically purchase land to develop real estate projects with the intention to begin construction within a 12- to 18-month period after the purchase of the land. We may also, from time to time, purchase land for subsequent resale. As of March 31, 2013, we owned approximately 888 hectares, of which 97.5% is located in Lima and 2.5% outside of Lima. We continually evaluate opportunities to purchase new land for our real estate development projects.

We have a 50.0% interest in Cuartel San Martín with Urbi Propiedades S.A. of Intergroup Financial Services Corp. owning the remaining 50.0%. Cuartel San Martín is a 68,000 m² former military base located in Lima’s upscale Miraflores district, where we plan to invest approximately US$680 million to develop a premiere mixed-use development consisting of approximately 98,000 m² of housing, 68,000 m² of office towers, a 61,000 m² shopping mall, and a 48,000 m² luxury hotel and conference center. Although we are still in the pre-construction approval phase and have not yet obtained all required building permits, we plan to begin construction of this project in the fourth quarter of 2013 and expect to complete the project through multiple stages within four years.

We have a 50.4% interest in Almonte, which owns approximately 800 hectares of undeveloped land in Lurin, located 30 km south of Lima. We previously sold 20 hectares of the land for industrial use, and we expect to sell 71 hectares of the remaining land for industrial use in the next five years. We also expect to develop affordable housing projects on the land once water and sewage services become available.

We also own a minority interest (approximately 20.8%) in Promoción Inmobiliaria del Sur S.A. (PRINSUR) of Inversiones Centenario, which owns approximately 983.83 hectares of undeveloped land also located in Lurin. We expect to develop affordable housing projects on the land once water and sewer services become available. Our proportional interest in this land is not included in our land bank.

Financing

We generally fund land purchases for our housing and commercial real estate projects through cash from our operations. For our affordable housing projects, we generally partner with real estate investment funds and insurance companies that provide between 60% and 70% of the total capital required to purchase the land and cover certain pre-construction costs in exchange for equity in the project. Once we acquire land for a particular real estate development project, we obtain working capital through a credit line from a financial institution, which we utilize to finance additional project needs as they arise. We also obtain financing through pre-construction sales for our affordable housing and housing projects and, to a lesser extent, our commercial real estate projects. Our affordable housing and housing projects generally require less outside financing because they are generally financed with pre-construction sales.

Sales and Marketing

We typically pre-sell our affordable housing and housing units prior to and during construction, and use the related proceeds we receive to finance the construction of the units. Our commercial and sales processes differ depending on the type of development and market segment of the development. We primarily sell our real estate development projects through an internal sales force that is assigned to particular projects and, to a lesser extent, external brokers on a non-exclusive, commission-fee basis. Our marketing efforts primarily consist of newspaper advertisements, radio and television commercials, billboards and promotional offers for referrals. We also advertise our real estate projects on our website.

We believe our brand is associated with product quality, professional operations and reliable post-sale customer service. We provide customer service call centers through which residents can report complaints or defects. Engineers respond with site visits, and repairs are made as long as the property continues to be covered by the applicable warranty or guarantee.

159

For our affordable housing projects, we provide post-sale customer service through our Ayni program, which aims to preserve the long-term value of our affordable housing developments by promoting a cooperative community life. Through this program, we distribute manuals that teach best practices for living in communities, offer leadership workshops, budget workshops, promote small business development, facilitate conflict resolution and provide other services. These services are provided for a six- to eight-month period following project delivery. In 2012, we initiated the Ayni contest for residents of our affordable housing projects with the aim of stimulating the sustainability of their community. Participants present an enhancement project for their community, such as a recreation center, and a jury selects the best project, which we fund and construct.

Competition

The Peruvian real estate development industry is highly competitive. The market is fragmented and no single company has a significant share of the national market. The principal competitors for our Real Estate segment are Paz Centenario Global S.A., Paz Centenario Inmobiliaria, Corporación Líder Perú S.A., Urbana Perú, Los Portales, Inmobiliari S.A., Imagina Grupo Inmobiliario, ENACORP, Besco S.A. and Gerpal. In the coming years, we expect more competition from domestic and foreign real estate development companies who recognize the growth potential in the Peruvian residential market. The main factors that drive competition are product design and amenities, price, location and post-sale service offerings.

Technical Services

Our Technical Services segment undertakes a broad range of activities, including (i) the operation and maintenance of infrastructure assets; (ii) information technology (IT) services for private clients and the government; and (iii) electricity networks services. Characterized by mid-to long-term contracts, our Technical Services segment further adds a more stable cash flow stream to our consolidated activities.

Operation and Maintenance of Infrastructure Assets

We began providing our operation and maintenance of infrastructure assets services in 1994 when we were awarded the concession for the Arequipa Matarani highway in southern Peru. With this experience, in 2003, we began providing operation and maintenance services to Norvial. In 2007, the Peruvian government initiated Proyecto Peru, a program aimed at maintaining roads not under concession to ensure their longevity. Proyecto Peru allowed us to develop new business opportunities providing maintenance services to more than 4,000 km of public roads in Peru. We believe the experience we have gained operating highway and transportation concessions positioned the company to capitalize on the Peruvian government’s initiatives to increase infrastructure development.

Our revenue in the operation and maintenance of infrastructure assets is generated either from fees we charge to Norvial, Survial, Canchaque and the Lima Metro to operate and maintain our concessions or from government payments through maintenance service contracts we have been awarded. As depicted in the chart below, we operate and maintain more than 5,000 km of Peruvian roads and highways, including our own highway concessions, in addition to the Lima Metro.

The below map illustrates the roads in Peru for which we currently provide operation and maintenance services.

We provide the following road operation and maintenance services:

• Routine Maintenance. These services aim to preserve roads through ongoing maintenance, including: road demarcation; cleaning; drainage; road fissure treatment, which seals cracks in roads to prevent water infiltration; slurry sealing; and micro-paving, which seals asphalt to prevent aging and improve resistance to water and surface wear.

• Periodic Maintenance. These services entail activities that are performed periodically, intended to prevent the occurrence or exacerbation of defects, conserve the structural integrity of roads and correct major defects.

• Emergency maintenance. This maintenance work is performed whenever the need arises, such as when natural disasters damage road surfaces.

We also administer toll stations and weighing stations; offer road patrolling services; operate assistance call centers; and provide emergency medical services.

The operation and maintenance services we provide to the Lima Metro aim to preserve the mass transit system through ongoing maintenance, including cleaning of the trains and stations and providing train operators, among other services.

With respect to operation and maintenance contracts with the Peruvian government, we obtain new contracts through public bidding. With respect to contracts with our Infrastructure segment, we participate in direct negotiation. Contract length typically ranges from three to five years.

163

IT Services

We began our IT services business in 1984 providing computer equipment to companies and evolved into a technology solutions provider in 2000, becoming one of the two largest providers of IT services in terms of 2011 revenues in Peru, according to International Data Corporation (IDC). In the early 1980s, Sonda, one of the main IT services providers in Latin America, was looking for a partner to represent Digital Equipment Corp. (currently, Hewlett-Packard) for the sale of hardware in Peru. Sonda’s need coincided with our diversification strategy and, therefore, we decided to jointly constitute GMD. In 1994, we bought out Sonda. Nowadays our main focus is the provision of business process and IT outsourcing services, and providing the necessary corresponding equipment, to well-known large companies and public institutions in Peru.

The infrastructure through which we operate our business includes two call centers with a total of 181 workstations and three data centers. In addition, we have successfully entered into strategic partnerships with key international IT vendors such as Cisco Systems, Microsoft, Hewlett-Packard, Oracle, SAP, IBM, Citrix, VMware, CA Technologies and Louis Berger Group.

The table below sets forth selected financial information relating to our IT services.

Clients

We provide services to our clients pursuant to service level agreements which enable us to customize each contract to the needs of the particular client. We set specific parameters and standards which can include maximum times for response and levels of equipment performance, among others. The average term of our contracts is three to five years and we have achieved a significant level of contract renovation.

We have built a strong client base in Peru, including local affiliates of global companies, spanning a broad range of industries, including key clients from the energy, government, banking, insurance, pension funds, industrial, commercial, education and mining sectors. Our principal clients are affiliates of Barrick Gold Corporation, Repsol, BBVA Banco Continental, Honda, Telefónica, the Peruvian National Office of Electoral Processes (Oficina Nacional de Procesos Electorales), the Peruvian National Pension System (Sistema Nacional de Pensiones), the Peruvian SUNAT, AFP Integra- Sura Group, Backus, BELCORP and UNIQUE.

Competition

The IT services industry is highly competitive. The market includes both international companies and local or regional companies. Our main competitors, which are sometimes also our partners, include companies such as IBM, Tata Consultancy Services, Sonda, Indra, among others.

Electricity Networks Services

We offer field and specialized services consisting of installation and routine operation and maintenance of electricity infrastructure, primarily for power utility companies in Chile and, to a lesser extent, Colombia, Brazil and Peru. Field services include day-to-day services and troubleshooting required to maintain the electric grid. Specialized services require more sophisticated and more tailored technology and expertise. With over 20 years operating experience developing, installing, operating and maintaining metering systems, we have also developed a broad range of specialized solutions to reduce electricity theft, one of the main concerns for power utility companies in Latin America.

The field services we provide include, among others, installing and maintaining medium- and high-voltage electricity networks and public lighting networks; connecting new residential, commercial and industrial customers to the electrical grid; disconnecting and reconnecting the power supply of our clients’ customers; meter reading; verification of electricity theft; and the installation of meters and anti-theft solutions. We also provide services that include changing and repairing damaged electrical equipment and maintaining, transferring and expanding the electrical grid. We have developed a sophisticated management system to monitor the efficiency of the field services we provide and increase the daily productivity of our field crews.

We also provide specialized services, which involve more technical expertise and specialized equipment, including the monitoring of electrical consumption for approximately 340,000 industrial, commercial and residential customers. We have developed specialized metering systems and anti-theft solutions for the Latin American markets. We believe we are one of two companies with a relevant market penetration of these anti-theft solutions for power utility companies in our markets. We also operate laboratories that offer an array of services in response to local regulation requirements, such as meter certification, equipment testing and theft reports.

In Brazil and Chile, we also operate the warehouse facilities of local power utility companies, which store and distribute the necessary equipment for operations, such as cables, insulators and meters. In addition, in Chile, we lease residential electricity meters to a power utility company, for which we also provide maintenance services. We have formed strategic alliances with equipment manufacturers in order to develop and commercialize specialized metering systems and anti-theft solutions.

The chart below sets forth the percentage of our 2012 revenues in each of the countries where we operate.

Contracts and Clients

We typically provide our services pursuant to long-term contracts ranging between three and five years. Most of our contracts are awarded through a non-public bidding process, although some contracts are negotiated directly with the client.

Our principal clients are power utility companies and, to a lesser extent, industrial clients, predominantly in the private sector. In Peru, we also provide services to the telecommunications industry. Our principal clients are the distribution companies of Enersis. Over the years, we have worked with the principal power utility companies in the region, including Chilectra, Saesa, Chilquinta, AES, E-CL, Endesa Chile, Ampla, Coelce, Cemig, Coelba, Elektro, Light, Codensa, Emgesa, EEC, Enertolima, Emcalo, Edelnor, Electrocentro, Enosa, Claro and Telefonica.

Competition

The market for electricity networks services is highly fragmented and no single company has a significant share of the national market in the countries where we operate. We primarily compete with small, local privately-held service companies. We expect competition to increase in the coming years as electricity consumption grows in response to the economic growth, and relatively low per capita consumption, in the countries where we operate. The main factors that drive competition are safety; product and service quality; reliability; price; and ability to respond to increased industry regulations.

Backlog

We define our backlog as the U.S. dollar equivalent value of revenue we expect to realize in the future as a result of performing work under multi-period contracts that we have entered into. Backlog is not a measure defined by IFRS, and our methodology for determining backlog may not be comparable to the methodology used by other companies in determining their backlog. For contracts denominated in nuevos soles or other local currencies, amounts have been converted into U.S. dollars based on the exchange rate published by the SBS on December 31 of the corresponding year, and in the case of amounts as of March 31, 2013 based on the exchange rate published by the SBS on such date.

We do not include backlog in this prospectus in our Infrastructure segment for: (i) our Norvial toll road concession because its revenues from the concession are derived from toll fees charged to vehicles using the highway, and, as a result, such revenues are dependent on vehicular traffic levels; and (ii) our Energy line of business because: (a) its revenues from hydrocarbon extraction services are dependent on the amounts of oil and gas we produce and market prices, which fluctuate significantly; (b) our revenues from our gas processing plant are dependent on the amount of gas we process and market prices for natural gas liquids, which fluctuate significantly; and (c) our revenues from our fuel storage terminal operation partially depend on the volume of fuel dispatched, such revenues are not material to our consolidated results of operations and the concession for such services is scheduled to terminate in August 2014.

167

When we present backlog on a segment basis, we do not include eliminations that are included in our consolidated backlog. For a description of how we calculate our backlog, see our segment backlog presented below.

Our consolidated backlog as of March 31, 2013 was US$4,291.3 million. As of March 31, 2013, we expect to recognize as revenues 37.1% of our backlog by December 31, 2013, 30.4% of our backlog by December 31, 2014 and 32.5% of our backlog thereafter. The following table sets forth the growth of our consolidated backlog from December 31, 2008 to March 31, 2013.

Backlog Growth (in US$ million)

Our backlog may not grow at recent historic rates and may decline. We cannot assure you that we will be able to continue obtaining sufficient contracts in the future in number and magnitude to continue to grow our backlog. Additionally, the amount of new contracts signed can fluctuate significantly from period to period due to factors that are beyond our control.

E&C Backlog

To include an engineering and construction contract in our backlog, we assume that each party will satisfy all of its respective obligations under the contract. We also make assumptions, in agreement with the client, regarding the total expected contract price in the case of unit price and cost-plus fee contracts and the amount of the contract that will be completed in each year. We adjust our backlog periodically to account for developments related to each project. For projects related to joint operations, we only include our percentage ownership of the joint operation’s backlog. Our E&C segment backlog does not include intersegment eliminations.

169

Our E&C backlog as of March 31, 2013 was US$3,064.9 million. As of March 31, 2013, we expect to recognize as revenues 37.4% of our backlog by December 31, 2013, 32.2% of our backlog by 2014 and 30.4% of our backlog thereafter. The following table sets forth the growth of our E&C backlog from December 31, 2008 to March 31, 2013.

E&C Backlog Growth (in US$ million)

The number and amounts of new contracts signed can fluctuate significantly from period to period. For example, two large mining services contracts were signed in the fourth quarter of 2012 for an aggregate amount of backlog of US$1.1 billion. During that same quarter we also recorded US$259 million in backlog from our Vial y Vives acquisition. These contracts and acquisition accounted for a significant portion of the extraordinary growth in our E&C backlog between December 31, 2011 and December 31, 2012 and explain in part the more gradual growth between December 31, 2012 and March 31, 2013.

The table below sets forth our ending E&C backlog for 2010, 2011, 2012 and the first quarter of 2013, accounting for opening backlog for each year, annual contract bookings and adjustments and annual revenues recognized.

	2010			2011			2012			Three months ended March 31, 2013
	(in millions of US$)									(unaudited)
Opening backlog (end of prior period)		905.0			1,064.1			1,839.6			2,925.4
Contract bookings and adjustments during the year		764.5			1,807.8			2,447.1			483.0
Revenues recognized during the period		(605.4	)		(1,032.3	)		(1,361.4	)		(343.5	)
Ending backlog (end of current period)		1,064.1			1,839.6			2,925.4			3,064.9

The table below sets forth our backlog at the reported years end and the ratio of such backlog to revenues earned in the subsequent two years.

(1) Revenues are reported under IFRS for such year and converted into U.S. dollars based on the exchange rate published by the SBS at the end of the corresponding year, which was S/.2.81 to US$1.00 as of December 31, 2010, S/.2.70 as of December 31, 2011 and S/.2.59 as of December 31, 2012.

The first section from the table above shows what the estimated backlog for the E&C segment had been as of each year-end period, between 2008 and 2011, as well as the portion of each year-end backlog that was estimated at the time to be executed in each of the next two years and thereafter. For example, E&C backlog as of December 31, 2008 was US$530 million, of which US$380 million was estimated at the time to be executed in 2009 (“T+1”), US$128 million in 2010 (“T+2”) and US$21 million in 2011 and thereafter.

The second section of the table shows actual E&C revenues for each of the years in the 2010-2012 period presented in accordance with IFRS.

The third section of the table shows E&C revenues to backlog ratios, calculated as the actual E&C revenues that were obtained in a year divided by what the estimated E&C backlog realization for that same year had been one year before and two years before. For example, the ‘T+1’ revenues to backlog ratio for 2009 was 1.20x (calculated as 2010 revenues of US$605 million divided by US$506 million, which was the portion of the backlog as of December 31, 2009 that was estimated at the time to be executed in 2010). This means that in 2010 we were able to generate actual E&C revenues of 1.20x times what the estimated E&C backlog for 2010 had been as of the previous year-end period.

172

Based on 2007 backlog of US$419 million, of which US$275 million was expected to be realized in 2008 and US$144 million in 2009, the ratios of E&C revenues (under Peruvian GAAP) to backlog for 2008 (T+1) and for 2009 (T+2) were 1.68x and 3.58x, respectively. Similarly, based on 2008 backlog of US$530 million, of which US$380 million was expected to be realized in 2009, the ratio of E&C revenues (under Peruvian GAAP) to backlog for 2009 (T+1) was 1.36x.

Our revenues in each of the reported years exceeded T+1 estimated backlog realization for the year because revenues were earned from, in addition to contracted amounts reflected in such backlog, new contracts signed during the year and change orders on backlog contracts. These positive effects were offset in part by delays in project execution and project cancellations. Our T+1 ratios have varied significantly from year to year because of the unpredictability and wide dispersion in size of new projects, change orders, delays and cancellations, and the variation in T+2 ratios is even greater because the effect of these factors increases with the passage of time. Our historical T+1 and T+2 ratios may not be indicative of future backlog realization ratios because the effect of these factors is unpredictable and we may not be able to generate revenues at multiples above our contracted backlog due to the factors explained above and because we may not be able to increase the scale of our operations to realize such incremental revenues. In particular, you should not assume that the ratio of our future E&C segment revenues for 2013 and 2014 to backlog as of December 31, 2012 that is currently expected to be realized in each of those years will be comparable to our historic ratios shown above. See “Risk Factors—Risks Related to Our Company—Our backlog and our ratio of historical backlog to revenues may not be reliable indicators of future revenues or profit.”

Infrastructure Backlog

In reflecting an Infrastructure contract in our backlog, we assume that each party will satisfy all of its respective obligations under the contract. For our Infrastructure backlog, we only include contracted revenues expected to be paid during the next three years following the backlog calculation date. Infrastructure backlog in this prospectus does not include our Norvial toll road concession or our Energy line of business. Our Infrastructure segment backlog does not include intersegment eliminations. We calculate our Infrastructure backlog as follows:

• for the Lima Metro, we estimate the number of trains in operation in the applicable period. Our Infrastructure backlog assumes that: (i) for 2013, we will initially operate five trains and gradually add 11 trains beginning in June 2013, which in the aggregate will travel 1,436,000 km for that year; (ii) for 2014, we will initially operate 16 trains and expect to add 8 trains by the third quarter of 2014, which in the aggregate will travel 1,670,873 km for that year; and (iii) for 2015, we will operate 24 trains in both the first and second stretches of Line One, which in the aggregate will travel 2,603,453 for that year. The above assumptions are based on terms under our concession. However, as of the date of this prospectus, although we have received the 11 additional trains, we are currently awaiting approval from the Ministry of Transport and Communications to begin operating these trains;

• for our Survial and Canchaque concessions, we assume our contractually agreed upon annual fee, adjusted for inflation. For our 2014 and 2015 backlog, we utilize the same adjustment amount that was utilized for our 2013 fee, which has already been negotiated; and

• for La Chira, the agreed-upon fee that the government will pay for the construction of the waste water treatment plant is reflected as backlog for 2013 and 2014. For 2015, backlog is calculated to include the fees we will receive under the concession for our operation and maintenance, with no adjustment for inflation because 2015 is expected to be the plant’s first year of operations.

173

Our Infrastructure backlog as of March 31, 2013 was US$443.0 million. As of March 31, 2013, we expect to recognize as revenues 24.6% of our backlog by December 31, 2013, 30.3% of our backlog by December 31, 2014 and 45.1% of our backlog in 2015. The following chart sets forth the growth of our Infrastructure backlog from December 31, 2010 to March 31, 2013.

Real Estate Backlog

Our Real Estate segment backlog reflects sales contracts with buyers for units that have not yet been delivered and will be recognized as revenues once they are delivered.

Our Real Estate segment backlog as of March 31, 2013 was US$115.2 million. As of March 31, 2013, we expect to recognize as revenues 74.3% of our backlog by December 31, 2013, 19.4% of our backlog in 2014 and 6.4% of our backlog thereafter.

The following pie chart sets forth our Real Estate backlog breakdown by type of real estate activities as of March 31, 2013.

Technical Services Backlog

In reflecting a Technical Services contract in our backlog, we assume that each party will satisfy all of its respective obligations under the contract and that work under the contract will be completed on a straight-line basis. Our Technical Services segment backlog does not include intersegment eliminations.

Our Technical Services backlog as of March 31, 2013 was US$818.9 million. As of March 31, 2013, we expect to recognize as revenues 37.4% of our backlog by December 31, 2013, 26.3% of our backlog in 2014 and 36.3% of our backlog thereafter. The following chart sets forth the growth of our Technical Services backlog from December 31, 2008 to March 31, 2013.

Employees

We have developed an extensive and talented team, including more than 3,500 engineers, that gives us the capability and scale to undertake large and complex projects. We also have access to a network of approximately 62,000 manual laborers throughout Peru that can supplement our workforce when required by our projects. Moreover, we have the flexibility to engage our own workers on projects outside Peru, avoiding the need to seek new employees in other countries.

As of December 31, 2012, we had a total of 28,257 full-time employees, including approximately 12,000 manual laborers, a number that fluctuates depending on our project backlog. At such date, we also worked with 4,452 employees of subcontractors. Occasionally, we employ subcontractors for particular aspects of our projects, such as carpenters, specialists in elevator installation and specialists in glassworks. We are not dependent upon any particular subcontractor or group of subcontractors. As of December 31, 2012, 24% of our employees worked outside Peru. The following table sets forth a breakdown of our employees by category as of December 31, 2012.

Salaried Employees	Engineering and Construction		Infrastructure		Real Estate		Technical Services		Corporate		Total

177

The following chart sets forth the growth of our total employees from December 31, 2010 to December 31, 2012.

Total Employees

Our talent development system has allowed us to develop a team of professionals who are able to design and implement sophisticated projects. Our talent development system is based on three main pillars: (i) specialized training for all levels, including senior management; (ii) mentoring; and (iii) feedback from managers to employees.

We have implemented programs to attract young and qualified candidates. Our Trainee, Academic Excellence and Young Engineers programs, offer various types of internships and training opportunities to engineering students and recent graduates, rewarding the most successful candidates with the opportunity to work as full-time, permanent employees. Our focus is not only to attract talented people but also to retain them. Therefore, during the last five years we have worked together with Great Place to Work®, a human resources consulting, research and training firm, to measure our employee’s satisfaction with the working environment. According to studies carried out by Great Place to Work® during 2012, 70% of our engineers, technical specialists and other professional employees confirmed that we are a “great place to work.” Moreover, our subsidiaries Viva GyM and GMP were recognized by Great Place to Work® as being among the 45 best companies to work for in Peru.

Through our Corporate Learning Center, we offer continued education opportunities through a wide selection of courses and training programs targeted at each level. We believe the knowledge that our employees gain through these programs is reflected in the way they work and relate to our clients, adding value in every step. During 2012, we invested US$7.7 million in continuing education, reaching approximately 304,000 hours of capacitation activities for our employees.

We place significant emphasis on instilling our core corporate values of quality, professionalism, reliability and efficiency and on promoting safety, environmental sustainability and social responsibility throughout the entire organization. Our Code of Conduct and Charter of Ethics regulate the conduct of our employees while promoting the foregoing values. In addition, our employees participate in ethics seminars on a periodic basis.

Substantially all of our manual laborers and some other employees are members of labor unions. Our practice is generally to extend the benefits we offer our unionized employees to non-unionized employees. We consider our current relationship with unions to be positive.

In our E&C segment, collective bargaining agreements are negotiated at two levels: on an annual basis between the National Federation of Civil Construction and the Peruvian Chamber of Construction, without our

178

direct involvement; and on a per project basis directly between the unions and our project committees, in accordance with such annual agreement. In addition, some of our personnel in our gas processing plant belongs to the labor union Unicode Workers Union GMP S.A. We currently have collective bargaining agreements with some of our gas processing plant workers. In the case of our operation and maintenance of infrastructure assets business, some of our personnel in CAM Perú are subject to a collective bargaining agreement. These collective bargaining agreements are negotiated on an annual basis.

Safety

In 2012, our E&C subsidiary GyM had an accident incidence rate of 0.29, calculated over 64,202,006 hours worked. In 2011, GyM had an accident incidence rate of 0.52, calculated over 52,979,699 hours worked, which was lower than that of private construction companies in the United States for the year, which had an average of 3.90, as reported by the Bureau of Labor Statistics of the United States Department of Labor. In 2010, 2011 and 2012, we had two, one and two fatalities, respectively.

Our occupational health and safety management system in our subsidiaries GyM, GMP and GMI is certified by OHSAS 18001. We believe a safe job site contributes to our reputation and ability to gain new business while enhancing employee morale and reducing costs and exposure to liability. We train our employees in safety, environment, occupational health and related topics, and have trained and certified experts in risk management and prevention who disseminate and regulate risk prevention standards and procedures. We have more than 400 staff members across our subsidiaries dedicated to health, safety and environmental matters, and at least two and up to 35 health, safety and environmental employees are assigned to each E&C project we undertake depending on the nature of the project and the client’s requirements. Moreover, each project manager is responsible for compliance with our safety requirements and for the protection of our employees.

To ensure safe conditions, we perform preventive and routine maintenance on all of our properties, worksites, systems and machinery, and make repairs and replacements when necessary or appropriate. We also conduct routine and required inspections of those properties in accordance with applicable regulation. Furthermore, we continually monitor, test, and record the effectiveness of our safety measures and assure that the highest risk segments receive the highest priority for scheduling internal inspections or tests for integrity.

Insurance and Contingency Planning

We have insurance coverage for fire; strike, riot, malicious damage, vandalism and terrorism; loses or damages to construction machinery and equipment; destruction or disappearance of property; civil liability, including physical harm to third parties; professional liability; transportation; vehicle theft, collision, rollover, fire and accidents; and directors and officers liability. Additionally, we carry different policies for specific risks related to our business segments. Our management considers this coverage to be sufficient to cover probable losses and damages, taking into consideration the nature of our activities, the risks involved in our transactions and the advice of our insurance brokers.

We also have contingency plans in place in order to protect our company and the interests of our clients. In the event of an emergency, we have procedures in place designed to minimize any resulting interruption in service to our most critical business processes.

Moreover, in the event of an emergency, we have systems and procedures in place that minimize the impact of unplanned downtime to our IT services’ clients. Our data centers have redundant facility systems and infrastructure to provide continued operation on each of them, complying with international standards such as ISO/IEC 27001 and ISO 9001.

179

Warranties

For certain of our contracts, we are required to provide performance bonds to ensure compliance with contractual obligations such as construction works, operation and maintenance of infrastructure assets, among others. The amount of the performance bond varies on a case-by-case basis, depending on the value of the project. Performance bonds are usually renewed annually until the contractual obligation which they intend to guarantee is fully satisfied.

As part of our real estate sales contracts, we provide a six-months warranty for latent defects, which covers hidden flaws not discoverable through inspection. The warranty extends to a five-year term if the defects are caused by: (i) the use of materials below the requisite quality standards; (ii) poor execution; or (iii) faulty land. We also provide a five-year warranty for structural defects, and assume the terms and conditions of our finishes suppliers’ warranties.

We provide warranties in connection with our IT services. All government contracts include a latent defects clause, in accordance with Article 51 of the Procurement Act which establishes a minimum warranty of one year, although, for some contracts, we provide warranties for two or three years. For contracts involving the sale of equipment or licensing, we provide the manufacturer’s warranty and, if a claim arises, we transfer the claim to the manufacturer unless we provided an extended warranty. For software development contracts, we provide a one to three years good performance warranty.

We have had no material disbursement or expenditure related to our warranties in the recent past.

Quality Assurance

The quality of our services is backed by the following certifications:

• Engineering and Construction: ISO 14001 and ISO 9001

• Infrastructure:

• GMP: ISO 14001 and ISO 9001

• Technical Services:

• Operation and Maintenance of Infrastructure Assets: ISO 9001

• IT Services: ISO 9001, ISO 27000 and CMMI-3

• Electricity Networks Services: ISO 14001 and ISO 9001

Properties, Plants and Equipment

Approximately 89% of our assets is located in Peru, with the balance located primarily in Chile. At December 31, 2012, the book value of all our land (excluding real estate inventories) and buildings, machinery and equipment was US$367.7 million. We currently lease certain machinery and equipment from vendors. The term of our leasing contracts ranges from two to five years, depending on the nature of the equipment. Leased machinery and equipment are capitalized for accounting purposes. Our principal executive offices, which we lease, are located at Av. Paseo de la República 4667, Surquillo, Lima 34, Peru. We are constructing additional office space for our corporate use, which we expect to complete in the beginning of 2014.

Legal and Administrative Proceedings

We may, from time to time, become subject to various legal and administrative proceedings that are incidental to the ordinary conduct of our business. We are currently not party to any material legal or administrative proceedings.

180

Corporate Social Responsibility

We aim to attract and develop our human capital through various training, mentorship and rewards programs in order to maintain our position as the best place to learn and work in the engineering field in Peru. We also seek to promote social good by continuing to foster relationships with the communities that surround the areas of operation of each of our business segments. As part of our citizenship building efforts, among other things, we provide: necessary tools for improving the employability and economic livelihood of citizens; create basic infrastructure to promote the use of public spaces as cultural spaces and training grounds for citizens; and create spaces that not only provide benefits, but also encourage citizens to actively participate in their maintenance.

Our social responsibility efforts have been recently recognized by the award of prizes such as the “Latin American Award for Corporate Social Responsibility 2012” awarded by the Inter-American Federation of the Construction Industry (FIIC), the “Business Creativity Award” granted by the Peruvian University of Applied Sciences (UPC) and the recognition as the “Peruvian Model Company” by the Lima Chamber of Commerce (CCL).

Our model of sustainable development is based upon building relationships of trust. In our projects we consider the needs of local communities with respect to generating employment; the expectations of our customers regarding the particular goals of the project; the demand of the state for a trained service provider; and investors who wish to entrust their capital to a company that follows best practices in corporate governance and social responsibility. The following is description of our main corporate social responsibility projects:

• Our social support program “Ayni” is intended to achieve the sustainability of our affordable housing projects by encouraging the responsible and committed participation of the owners of the units. This program has provided social training to more than 6,000 families in order to strengthen their leadership skills, integration and mutual respect.

• Through our “Metro Culture” program, we transform our trains and train stations into centers of social and cultural education. According to a 2012 poll, 97% of the Lima Metro users think that we have contributed to the development of the city and 92% believes that we have generated better citizens.

• Our “Road Management” program provides members of surrounding communities with the necessary civic and technical tools to make use of the roads and contribute to their maintenance by, for example, providing education on road safety and environmental protection. Moreover, we work on turning regular roads into touristic routes through the development and dissemination of guides, websites and training local communities to help develop skills in tourism.

• Our “Development of Local Labor Capacity” program (Programa Desarrollando Capacidades Laborales en las Zonas de Influencia) improves the employability of the local population, providing training that directly promotes their employment in our projects as well as providing other construction-related workshops which contribute to their development in community affairs. Since its creation in 2006, 18,000 persons have participated in this program, receiving more than seven hundred thousand hours of training.

181

REGULATORY MATTERS

Set forth below is a description of the regulatory framework applicable to our company. We believe we are in compliance, in all material respects, with applicable laws and regulations in all of our business segments.

Engineering and Construction

Regulatory Framework Applicable to Contracts with the Public Sector

Peru’s State Contracting Law, approved by Legislative Decree No. 1017 (Ley de Contrataciones del Estado) and its regulation approved by Supreme Decree No. 184-2008-EF, govern services and construction agreements entered into with public entities. Article 10 of the Supreme Decree No. 184-2008-EF establishes that, at the beginning of the contracting process, the contracting public entity must prepare a technical file describing the characteristics of the services it intends to purchase and the selection process for its counterparts, among other specifications such as a feasibility statement in accordance with the Peruvian Public Investment National System.

The selection processes are established in Articles 15, 16, 17 and 18 of Peru’s State Contracting Law as follows:

• public biddings (licitación pública) applicable to goods, supplies and works;

• public tenders (concurso público) applicable to services;

• direct award (adjudicación directa) applicable to goods, services and works, which can be public or directed at select participants depending if the value is equal to or higher than 50% of the maximum amount set forth in the state budget regulation for direct award; and

• lowest amount award (adjudicación de menor cuantía) applicable to goods, services and works whose value is lower than one-tenth of the minimum limit established by the state budget regulation.

With the exception set forth in Article 22 of the Supreme Decree No. 184-2008-EF, the selection processes include the following phases: notice; registration of participants; submission and reply of inquiries; submission and reply of comments; preparation of the terms and conditions of the selection process; submission of bids; evaluation and qualification of bids; and adjudication.

Article 9 of Peru’s State Contracting Law establishes that participants of any of the foregoing selection processes must be registered in the Peruvian National Registry of Suppliers (Registro Nacional de Proveedores) and must not be disqualified from contracting with the state. Article 252 of the Supreme Decree No. 184-2008-EF establishes that this registration is renewable as long as a request is submitted to the Peruvian National Registry of Suppliers 60 days prior to expiration of the registry.

Bidders may participate in the selection process as part of a joint operation, in which case all members of the joint operation must be registered in the Peruvian National Registry of Suppliers and will be jointly liable for all consequences arising from the joint operation’s participation in the selection process and the execution of the agreement.

GyM and GMI are registered in the Peruvian National Registry of Suppliers as a construction and a consulting company, respectively.

Article 40 of the Supreme Decree No. 184-2008-EF establishes the types of contracts that may be entered into by public entities:

• lump-sum (sistema a suma alzada), applicable when the amounts, magnitudes and quality are determined in the terms and conditions of the selection process. The bidder submits its proposal indicating a fixed amount and a term for the completion of the agreement;

182

• unit price, rates or percentages (sistema de precio unitario, tarifas o porcentajes), applicable when the nature of the service to be provided does not allow accurate determination of the required quantities; and

• lump-sum and unit price, rates or percentages mix (esquema mixto de suma alzada y precios unitarios), applicable when accurate determination of the quantities required for some of the components cannot be made.

Article 41 of the Supreme Decree No. 184-2008-EF establishes that, in the case of goods and works, the terms and conditions of the selection process must indicate the execution type of the agreement as follows:

• “turn-key” (llave en mano), when completion is subject to the construction, equipment and operations, and, if applicable, the submission of the technical file in connection with the bidding process; and

• bid contest (concurso oferta), when completion is subject to the submission of the technical file, the completion of the work or land, as applicable. This completion type is only applicable to lump-sum contracts and public bidding selection process.

Peru’s State Contracting Supervising Agency (Organismo Supervisor de las Contrataciones del Estado, or “OSCE”), a public-sector entity within the Peruvian Ministry of Economy and Finance, supervises and oversees the selection processes carried out by public entities; manages the Peruvian National Registry of Suppliers; imposes penalties to suppliers that violate the provisions set forth in Peru’s State Contracting Law, its regulation and other related provisions; and informs the government’s General Controller (Contraloría General de la República) regarding violations to the regulation when damages are caused against the state.

Regulatory Framework Applicable to Contracts with the Private Sector

Parties to a private-sector agreement may freely determine the contract type and its contents as long as it complies with certain legal requirements, including the provisions set forth in Article 1353 of the Peruvian Civil Code. GyM, GMI and Stracon GyM participate in private-sector contracts for engineering and constructions.

Construction Activities in Peru

Legal Framework

Legislative Decree No. 727 declared that construction activities in Peru are in the public interest and of preferential national interest. According to Section F of the Fourth review of the United Nations International Statistical Industrial Classification (ISIC), construction activities typically consist of the construction of dwellings, buildings and stores; and the construction of large scale infrastructure projects such as highways, bridges, tunnels, railways, irrigation systems, sewage systems, industrial facilities, pipelines and electric lines, among others. GyM has developed numerous projects in the construction sector. Currently, the company focuses on buildings (ISIC Division 41), civil works (ISIC Division 42) and specialized activities (ISIC Division 43).

Construction entities must comply with the National Building Regulation (Reglamento Nacional de Edificaciones approved by Supreme Decree No. 011-2006- VIVIENDA), which establishes that urban allotments and buildings must be developed in compliance with the rules governing safety, functionality, accessibility, habitability and environmental impact.

The Supreme Decree No. 009-97-SA, Law No. 26790 and Supreme Decree No. 003-98-SA require construction companies to have complementary high risk insurance for workers that perform high risk tasks. As of the date of this prospectus, GyM and Stracon GyM have this insurance coverage.

Environmental Regulations

Section 24 of the General Environmental Law approved by Law No. 28611 (the “General Environmental Law”) provides that all human activity likely to cause significant environmental impact is subject of regulation by the National System of Environmental Impact Assessment. The Peruvian Ministry of the Environment, through the Environmental Supervising and Enforcement Agency (Organismo de Evaluación y Supervisión Ambiental, or “OEFA”) supervises the compliance and enforces environmental rules related to mining, oil and gas, and electricity.

In addition to being responsible for the impact that their activities, by action or omission, may cause the environment, GyM and Stracon GyM are also subject to an environmental impact assessment and must obtain an environmental certification necessary to obtain project permits or licenses. These companies must also adopt measures for the management of hazardous materials intrinsic to their activities to mitigate the negative environmental impact their activities may have.

Civil Construction

The Supreme Decree No. 015-2012-VIVIENDA regulates the environmental aspects of projects related to housing, urbanism, construction and sanitation activities in urban or rural areas. The National Directorate of Housing, Urbanism, Construction and Sanitation supervises the compliance and enforces the applicable rules. Projects are categorized according to their environmental impact during and after their execution and different rules are established for each category including compliance with the following environmental studies prior to initiating construction works: (i) projects expected to cause minor environmental impacts require an environmental impact statement; (ii) projects expected to cause moderate environmental impacts require an semi-detailed environmental impact assessment; and (iii) projects expected to cause a major environmental impact require a detailed environmental impact assessment.

Other Subsectors

Depending on the subsector in which they operate, GyM and Stracon GyM are required to follow specific environmental provisions issued by the competent authorities.

186

Tax Legal Regime Applicable to Construction

Section 63 of Peruvian Income Tax Law approved by Supreme Decree No. 179-2004-EF, establishes that construction companies engaged in construction contracts for a period longer than one fiscal year can choose to be taxed under any of the following systems:

• allocate to each fiscal year the gross income resulting from applying the percentage of gross margin estimated for the work over the amounts collected for the same work; or

• allocate to each fiscal year the gross income calculated by deducting the costs corresponding to the tasks performed during that year from the amount collected or that is expected to be collected corresponding to that work.

In both situations, a special accounting registry must be kept for each project, which is meant to keep a record of the costs, expenses and income of each project in an account separate from the general analytical accounts (cuentas analíticas de gestión).

Until December 31, 2012, construction companies could defer revenues related to each individual project until the total completion of the project, provided the project was completed in three years or less. In such cases, the income was to be recognized in the fiscal year in which the project concluded or was delivered. In case the project was scheduled to conclude in a period exceeding three years, the results would be determined in the third year in accordance with the progress of the works over the three-year period. Beginning in the fourth year, results were determined following the foregoing methods.

Starting on January 1, 2013, in accordance with Legislative Decree No. 1112, which amended the Peruvian Income Tax Law, construction companies that adopted the deferral method are authorized to continue with the use of such method only with respect to income arising from the execution of work contracts initiated prior to January 1, 2013, until its completion and for execution of work contracts initiated on or after January 1, 2013 the deferral method is no longer accepted.

The Peruvian Income Tax Law also provides that the difference that may result from a comparison between the real gross income and the income assessed pursuant to any of the methods described above shall be allocated to the fiscal year in which the work concluded. Additionally, the company must apply the same system to all its construction contracts and must receive prior authorization from tax authorities to change the applied system.

Prevention of Money Laundering and Financing of Terrorism

Regulations for money laundering and terrorism financing prevention (SBS Resolution No. 486-2008) require construction and real estate companies to implement a money laundering and terrorism financing prevention system, including the appointment of a compliance officer, setting up a registry of operations and notifying the Financial Intelligence Unit of the SBS, the entity responsible for of supervising and enforcing compliance, of any suspicious activity.

Infrastructure

Private Investment in Public Infrastructure and Services

In Peru, promotion of private investment in public infrastructure and services is undertaken by Proinversión and commonly awarded through multi-party concession agreements among the concessionaire, Proinversión and the respective public entity. Private investment in public infrastructure is regulated by the Single Revised Text approved by Supreme Decree No. 059-96-PCM (Texto Único Ordenado or “TUO”) and its additional regulation approved by Supreme Decree No. 108-2006-EF.

187

In accordance with the TUO and its regulation, concessionaires are entitled to receive from the state: (i) in the case of self-financing projects, fees and tolls charged to end-users; (ii) in the case of co-financed projects, subsidies and payments from the public entity awarding the concession; and (iii) any other financing structure agreed upon by the parties.

The regulation of private-public partnerships allows public entities to participate, together with private investors, in the development or operation of public infrastructure and services. The regulation of private-public partnerships establishes that projects classified as self-financing and those classified as co-financed must comply with the requirements and procedures set forth in the Public Investment National System Law (Ley del Sistema Nacional de Inversión Pública) and in the Indebtedness National System law (Ley del Sistema Nacional de Endeudamiento) as amended.

Each of our subsidiaries Norvial, Survial, Canchaque and GyM Ferrovías has entered into a concession agreement with Proinversión and the Peruvian Ministry of Transport and Communications. La Chira has entered into concession agreements with Proinversión and Sedapal S.A. The abovementioned agreements were entered into in accordance with the provisions set forth in the TUO and its regulation, and with the regulation of private-public partnerships when applicable.

Infrastructure Construction and Safety

Infrastructure concessionaires must assure that the construction companies they hire to construct infrastructure projects comply with the foregoing rules relating to construction projects. In addition, companies engaged in road construction must comply with the guidelines issued by the Road and Railways General Directorate of the Peruvian Ministry of Transport and Communications and with the National Road Infrastructure Management Regulation regarding road construction, maintenance and safety. These regulations establish procedures for authorizing road construction and approving work contracts, among others.

Environmental Regulations

Peruvian environmental laws and regulations have become increasingly stringent over the last decade. All industries and projects are subject to Peruvian laws and regulations concerning water, air and noise pollution, and the discharge of hazardous substances. The principal legislation governing environmental matters is the General Environmental Law; the Law of the National System of the Environmental Impact Evaluation approved by General Law No. 27,446 (the “SEIA”); the regulations of the SEIA Law approved by Supreme Decree No. 019-2009-MINAM; and several environmental regulations that have been issued under the General Environmental Law, SEIA and other laws by the government with the collaboration of the Peruvian Ministry of the Environment.

Since the enactment of the General Environmental Law in October 15, 2005, several technical environmental regulations have been issued and this environmental regulatory framework is generally revised and updated regularly. Some regulations apply generally to Peruvian industries and some technical regulations are issued for specific industries.

The main environmental rules applicable to infrastructure projects include those described above in “Engineering and Construction—Environmental Regulation”

Peruvian Hydrocarbon Regulation

Our hydrocarbon operations are subject to governmental regulations as described below.

Exploration and Production

GMP is engaged in two major activities relating to the exploration and production of oil and gas: exploration and production of oil fields; and providing services to the oil industry.

188

Exploration and Production of Oil Fields

Peru’s hydrocarbon legislation regarding oil and gas exploration and production activities includes, among others, the Hydrocarbon Organic Law and the regulations governing the qualification of petroleum companies; the exploration and production of hydrocarbons; the transportation of hydrocarbons; hydrocarbons pipelines and safety requirements in such activities.

The foregoing regulations define the roles of Peruvian government agencies which regulate the oil and gas industry; provides the framework for the promotion and development of hydrocarbon activities based on the principles of private-sector competition and access to all economic activities; and sets the safety and security standards as well as the legal proceedings for carrying out operations.

The Peruvian Constitution establishes that the government is the sole proprietor of underground hydrocarbons within its national territory. However, the Peruvian government has granted Perupetro, a state-owned company authorized to negotiate and enter into agreements for the exploration and/or production of hydrocarbons, the ownership right over the hydrocarbons extracted which allows Perupetro to enter into such agreements. Furthermore, the Peruvian Ministry of Energy and Mines, the Environmental Evaluation and Supervision Agency (“OEFA”) and OSINERGMIN constitute public entities that play an active role in oil and gas regulation.

The Peruvian Ministry of Energy and Mines is responsible for devising energy and mining policies; supervising activities in the energy and mining sectors; and promoting investments in those sectors. Within the Peruvian Ministry of Energy and Mines, the General Directorate of Hydrocarbons (DGH) is responsible for regulating the development of oil and gas fields and the General Directorate of Energy-Related Environmental Affairs (DGAAE) is responsible for reviewing and approving regulations related to environmental risks associated with hydrocarbon exploration and production activities.

OEFA is a public entity ascribed to the Peruvian Ministry of the Environment and is responsible for evaluating and ensuring compliance with applicable environmental rules covering hydrocarbon activities, as well as for sanctioning proceedings. OSINERGMIN is a public entity ascribed to the Presidency of the Council of Ministers’ office and is responsible for ensuring compliance with safety and security standards in the hydrocarbon industry, as well as for sanctioning proceedings. GMP is subject to the supervision, authority and regulations enacted by the foregoing agencies.

Regarding hydrocarbon exploration and production activities, companies are required to enter into either a licensing or a services agreement with Perupetro; other contractual arrangements are permitted with prior approval from the Peruvian Ministry of Energy and Mines. The foregoing agreements are governed by private law and must be approved by the Peruvian Ministry of Energy and Mines and the Peruvian Ministry of Economy and Finance. In licensing agreements, licensees obtain authorizations to explore and produce hydrocarbons in a determined area, are granted ownership over the extracted hydrocarbons and are subject to the payment of royalties. Licensees may trade the hydrocarbons with no limitations on sales prices, except in the event of a national emergency.

Services agreements grant contractors the right to perform hydrocarbon exploration and production activities in a determined area and receive compensation according to the production of hydrocarbons. The contractor is technically and financially responsible for the operations, but Perupetro maintains the ownership over the hydrocarbons extracted. These are the type of contracts GMP is party to, with respect to Block I and Block V.

Services agreements are intended for the development, production and transportation of hydrocarbons, as well as for certain storage activities. Services agreement commonly include a minimum performance schedule guaranteed by performance bonds and require corporate guarantees to be issued to secure the contractor’s compliance to the provisions established by the parties.

189

Additionally, a company must be qualified by Perupetro prior to entering into hydrocarbon exploration and production agreements. In order to qualify, a company must meet the standards under the Regulations on the Qualification of Petroleum Companies, requiring companies to demonstrate that they have the technical, legal and financial capacity to comply with all the obligations they will assume under the agreement with Perupetro. Such capacities are measured according to the characteristics of the area to be explored or produced, the expected investment required for the project, and the strict fulfillment of the rules regarding prior consultation, citizen participation and environmental issues related to the operation’s performance. Upon a positive evaluation, the company is issued a qualification certificate that allows it to initiate the negotiations of the agreement; notwithstanding the company remains responsible for obtaining all other licenses, permits and approvals required by applicable regulation.

Under the current regulation, 30 years is the maximum term of services agreements for the production of crude oil. On the other hand, natural gas and condensates-related services agreement have a maximum term of 40 years. Graña y Montero acts as GMP’s guarantor in both our Block I and Block V production services agreements.

GMP must comply with Supreme Decree No. 043-2007-EM for its activities relating to exploration and production of hydrocarbons. The Peruvian Ministry of Labor and Employment Promotion is the authority responsible for the supervision and enforcement of the foregoing rules. See “Regulatory Matters—Infrastructure—Peruvian Hydrocarbon Regulation—Environmental Regulation” for more information on environmental regulation applicable to the oil and gas sector.

Services to the Petroleum Industry

Peruvian regulation provides that all companies that enter into a service agreement with any company that holds a licensing or services agreement must be registered as a subcontractor in the Hydrocarbons Public Registry in case they render any of the following services: (i) geological studies, geophysical studies, petroleum engineering related to drilling operations, production and well services; or (ii) construction of oil pipelines, gas pipelines, refineries and their maintenance, and specialized transportation by land, air, sea or river. In order to register a company as a subcontractor in the Hydrocarbons Public Registry, prior authorization from the General Directorate of Hydrocarbons (DGH) of the Peruvian Ministry of Energy and Mines is required.

On June 1, 2004, GMP was included as a subcontractor for the petroleum industry in the Hydrocarbons Registry of Lima’s Public Registry of Legal Entities; such registry remains in force as of the date of this prospectus.

Environmental Regulations

The Peruvian Ministry of Energy and Mines is responsible for enacting environmental regulation for the oil and gas sector. The Oil and Gas Environmental Protection Regulation, approved by Supreme Decree No. 015-2006-EM, sets out the legal framework and specific rules applicable to the exploration, production, refinement, processing, transportation, commercialization, storage and distribution of hydrocarbons, with the aim of preventing, controlling and remedying the negative environmental impacts arising from the foregoing activities.

The Peruvian Ministry of the Environment establishes general rules applicable to different activities in several sectors, in contrast to the specific rules enacted by the Peruvian Ministry of Energy and Mines regarding the oil and gas sector. Environmental laws and regulations are enforced by the National Environmental Enforcement Agency, OEFA (Organismo de Evaluación y Fiscalización Ambiental) which was created in 2008. Sanctions range from warnings and fines to suspensions of activities and mitigation of environmental damages, among others. In this regard, a breach of the obligations contemplated in the Environmental Impact Assessments in the hydrocarbons sector may originate fines up to 30,000 Tax Units (approximately US$42 million) according to the applicable law.

190

The main environmental rules applicable to GMP’s hydrocarbon projects include:

• filing environmental impact study or adopting the necessary measures to prevent and/or mitigate the environmental impact resulting from their activities;

• meeting minimum size, environmental and safety requirements applicable to worksites;

• handling and storing of hydrocarbons pursuant to safety and environmental requirements;

• establishing programs to monitor environmental issues; and

• providing training on environmental matters related to employee and personnel activities and responsibilities, especially with respect to regulations and procedures established for environmental protection and the environmental and legal consequences of non-compliance.

Operation of Terminals

In accordance with the Glossary, Acronyms and Abbreviations for the Hydrocarbons Subsector approved by Supreme Decree No. 032-2002-EM, a terminal is a facility that includes storage tanks, submarine lines or docks for receiving or dispatching liquid hydrocarbons and facilities related to activities of storage and reception and/or dispatch of liquid hydrocarbon from/to vessels.

Consorcio Terminales is a joint operation among GMP and Oiltanking Peru S.A.C. which currently operates nine of Petroperú’s terminals in Peru: (i) the South Terminals of Pisco, Mollendo, Ilo, Juliaca and Cuzco; and (ii) the North Terminals of Eten, Salaverry, Chimbote and Supe. Consorcio Terminales provides hydrocarbons handling and storage services in Peru for gasoline, aviation fuel and diesel, among others.

The operation of both the South and North Terminals, was granted through the “South Terminal Operation Agreement” and the “North Terminal Operation Agreement” (the “Operation Agreements”) dated February 2, 1998, by and among Petroperú and Consorcio Terminales. The Operation Agreements resulted from two tenders in accordance with Legislative Decree No. 674, and mandate that Consorcio Terminales, as operator of the terminals, be responsible for the storage, handling, additivation and dispatch of hydrocarbons in such facilities.

The initial term of the Operation Agreements was fifteen years; however the parties agreed to extend the duration of the agreement to an additional eighteen months ending in August 2014. The purpose of this extension was to undertake the additional investments that were necessary to satisfy the national demand increase and to perform operative and safety-related improvements to the facilities.

In executing its operations, Consorcio Terminales is committed to develop and follow a work program which must include an investment schedule. The work program performed included the installation of fire protection systems and loading systems, among others and was secured by a performance bond.

GMP’s activities as a part of Consorcio Terminales fall under the scope of the Hydrocarbons Storage Safety Regulation (Supreme Decree No. 052-93-EM). Consorcio Terminales is registered in the Hydrocarbon Registry of OSINERGMIN and is authorized to perform transportation activities such as loading and unloading hydrocarbons from vessels on the terminals. This regulation establishes the conditions under which GMP can operate and maintain storage facilities for hydrocarbons. For instance, the regulation specifies the technical requirements for storage systems, which vary depending upon the kinds of hydrocarbons stored. Moreover, pursuant to this regulation, GMP must establish procedures to minimize potential risks that these facilities present for employees, third parties and properties.

Gas Processing Plants

In accordance with the Glossary, Acronyms and Abbreviations for the Hydrocarbons Subsector approved by Supreme Decree No. 032-2002-EM, a processing plant is a facility where the natural characteristics of hydrocarbons are changed to break them into the different compounds that comprise them, as well as the

191

subsequent transformations to convert the hydrocarbons into fuel of specific qualities and suitable for transportation. This includes the facilities where the impurities, hydrogen sulfide, carbon dioxide, water and hazardous components are removed from natural gas.

Our processing and fractionation activities fall under the scope of regulations governing hydrocarbons refinement and processing including regulations on the design, construction, operation and maintenance of refineries and hydrocarbons processing plants, the oil refining process, the manufacture of natural asphalts, oil and lubricants, basic petrochemical activities and the processing of natural gas and condensates. In order to comply with these regulations, GMP must take cautionary measures in order to protect the safety of its employees and its facilities, protect the environment, preserve energy resources and ensure the quality of the products or services it delivers. For instance, GMP’s plant operations must be authorized by the General Direction of Hydrocarbons and comply with fire safety regulations. In the event of an accident, GMP must notify the Peruvian Ministry of Energy and Mines, the Peruvian Ministry of Labor and the Peruvian Social Security Administration.

Terms of our Concessions

Our concessions are subject to certain terms and conditions established in each concession agreement. During the term of the concessions, we are responsible for the construction and maintenance of the infrastructure necessary to their operation. The concession agreements establish minimum capital stock requirements for our concessionaire subsidiaries as follows: US$15 million, US$8 million, US$0.8 million, S/.46 million and S/.100 million for Norvial, Survial, Canchaque, La Chira and the Lima Metro, respectively.

The concession agreements establish grounds for termination including mutual agreement of the parties thereto, force majeure and breach of certain contractual obligations. Additionally, in the case of La Chira and the Lima Metro, the agreement can be terminated unilaterally by the grantor, with the payment of compensation. On the expiration date, all of the assets that are essential for the operation of the concession are considered the state’s property and no compensation is paid to the concessionaire.

In the event that changes in legislation or regulations that are exclusively related to the financial conditions of the earnings and/or costs associated with the investment, operation or conservation of the infrastructure, affect the economic terms of the contract by 10% or more, the concession agreements set forth economic terms adjustment mechanisms aimed at restoring the economic and financial equilibrium. See “Business—Infrastructure—Principal Infrastructure Lines of Business.”

Real Estate

Since 1987, we have been operating in the Peruvian real estate sector. In 2008, we incorporated Viva GyM to concentrate the group’s activities in this sector including promoting and managing real estate projects including affordable housing and housing and commercial real estate projects.

Zoning Regulations

Article 79 of the Municipalities Organic Law (Law No. 27972) establishes that municipal governments are the exclusive authority responsible for approving urban and rural development plans, as well as the zoning of the urban areas under their jurisdiction. Peruvian regulation establishes that urban zoning refers to the division of a municipal jurisdiction in zones for specific usages, such as residential, commercial, industrial or mixed-use.

The main zoning rules applicable to our real estate projects include the following:

• obtaining a construction license from the corresponding local municipality before commencing construction, reconstruction, conservation or repair of any property; and

• obtaining an inspection certificate issued by INDECI (National Institute of Civil Defense), the entity in charge of supervising that companies comply with the National Construction Regulation nationwide.

192

Environmental Regulations

The Environmental Protection Regulation for real estate, urbanism, construction and regularization related projects (Supreme Decree No. 015-2012-VIVIENDA) sets out to prevent, mitigate, control and remedy negative environmental impacts that may arise from real estate developments. Prior to initiating construction works, companies are required to obtain an environmental authorization from the Housing, Urbanism, Regularization or Construction National Directorate of the Peruvian Ministry of Housing, Construction and Sanitation and to comply with the provisions set forth in the corresponding environmental impact assessment.

The main environmental rules applicable to our real estate projects include the following:

• undertaking an environmental impact assessment; and

• requesting the environmental classification of our projects, which depends on the environmental risks associated therewith.

Licenses

MANAGEMENT

General

Our business and affairs are managed by our board of directors in accordance with our by-laws, shareholder meeting rules of procedure, board of directors rules of procedure, internal rules of conduct and Peruvian Corporate Law No. 26887 (“Peruvian Corporate Law”). Our by-laws provide for a board of directors of between five and nine members. Our shareholders may appoint an alternate director for each director to act on his or her behalf when absent from meetings or unable to exercise his or her duties. Alternate directors have the same responsibilities, duties and powers of directors to the extent they are called to replace them.

Directors are elected at a shareholders’ meeting and hold office for three years. Directors may be elected to multiple terms. Our current board of directors is composed of nine directors and no alternates. If a director resigns or otherwise becomes unable to continue with the duties, a majority of our directors may appoint one of the alternate directors, or in the absence of alternate directors, any other person, to serve as director for the remaining term of the board. In the first board meeting held after the annual shareholders’ meeting where members of the board are elected, the board of directors must elect among its members a chairman and a vice chairman if the shareholders’ meeting did not elect them.

The board of directors typically meets in regularly scheduled quarterly meetings and when called by any director or our Chief Executive Officer. Resolutions must be adopted by a majority of the directors present at the meeting and the chairman is entitled to cast the deciding vote in the event of a tie.

Duties and Liabilities of Directors

Pursuant to Article 177 of Peruvian Corporate Law, directors are jointly and severally liable to a corporation, shareholders and third parties for any damages caused by abuse of power, fraud, willful misconduct or gross negligence. In addition, pursuant to
Article 3 of Law No. 29720, as amended, directors of companies with common shares listed on the Lima Stock Exchange are liable to the company and its shareholders for damages caused by resolutions which are favorable to their individual interest (or the interest of a related party) to the detriment of the company’s interest if: (i) the listed company is a party to the transaction; (ii) the controlling shareholder of the listed company controls the legal entity acting as counterparty; (iii) the transaction is not carried out on an arms length basis; and (iv) at least 10% of the listed company’s assets are involved in the transaction. A director cannot be found liable if he/she did not participate in the respective meeting or if the director’s express disagreement is noted in the corresponding record.

Article 180 of the Peruvian Corporate Law requires a director with a conflicting interest on a specific matter to disclose such interest and abstain from the deliberation and decision-making process with respect to such matter. A director who violates this requirement is liable for any damages caused to us and may be removed by a majority of the board of directors upon request of any member of the board or by a majority vote of the shareholders.

Pursuant to Article 181 of Peruvian Corporate Law, shareholders are entitled to protect the interest of a company through derivative law suits against directors in order to remedy or prevent a wrong to the corporation. In addition, pursuant to Article 4 of Law No. 29720, with respect to companies listed on the Lima Stock Exchange, a shareholder holding shares which represent at least 10% of the paid capital may bring said action against the directors.

In 2012, total compensation paid to our board of directors amounted to S/.4,544,861 including compensation paid to directors that serve on our subsidiaries’ board of directors. In 2012 total compensation paid to our executive officers amounted to S/.24,308,652. See “Industry and Regulatory Matters—Labor Regulations” for additional information on profit sharing regulatory requirements.

Neither we nor any of our subsidiaries have entered into any agreement that provides for any benefit or compensation to any director or senior executive upon expiration of his or her term. Under Peruvian law, unless we dismiss someone for justified cause, we are required to pay the dismissed employee (but not directors) 1.5x annual salary for every year with the company for a period not to exceed 12 years. We are not required to make such payments in the event of voluntary termination. Although we have no ongoing obligation to do so, in the past we have provided, and in the future we may provide, such benefits to our executive officers upon their retirement. We have not set aside or reserved any amounts to provide for pension, retirement or other similar benefits.

Executive Compensation Plan

We establish and pay executive compensation in compliance with applicable labor and tax regulations and corporate governance standards and in accordance with market conditions.

We establish pay scales taking into consideration executives’ responsibilities, including the degree of complexity of those responsibilities, power of decision-making and scope of supervision entrusted.

The fixed salary component of compensation is established for each position based on a pay scale. Fixed salary includes family allowance and cost of living payments, if applicable. We evaluate executives at least once a year to develop action plans in furtherance of continuously improving management performance.

The variable component of compensation is paid to executives and other employees for meeting specific goals, and is related both to his or her performance and our financial results. Variable compensation is typically paid as an annual bonus.

In addition, labor regulation establishes a mandatory profit sharing provision of 5% of our total annual taxable income, to be distributed among all employees, calculated based on a formula established by law that considers the days worked in the year and remuneration.

Our executives also receive additional benefits, typically non-pecuniary. The benefits granted include: (i) a vehicle owned and maintained by the company, with the purpose of facilitating transportation of executives in the performance of their functions; (ii) a fuel allowance to offset transportation costs in the performance of their functions; and (iii) an insurance policy, including work accident and high risk coverage.

203

In addition, we have established a plan for certain executives effective March 2013 that awards cash bonuses for the exclusive use of purchasing shares of our company or of our subsidiaries. The executive must agree to hold the shares for a specific period. If the executive is no longer employed with the company during such period, we are entitled to repurchase the shares at the original purchase price. This benefit is awarded at the discretion and subject to the approval of the Human Resource Management and Social Responsibility Committee of our board of directors.

RELATED PARTY TRANSACTIONS

Peruvian Law Concerning Related Party Transactions

Peruvian law sets forth certain restrictions and limitations on transactions with certain related parties.

For instance, from a tax standpoint, the value of those transactions must be equal to the fair market value assessed under transfer pricing rules, i.e., the value agreed to by non-related parties under the same or similar circumstances. Similarly, companies with securities registered in the Peruvian Public Registry of Securities (Registro Público del Mercado de Valores), such as us, are required to comply with the following rules:

• The directors and managers of the company cannot, without the prior authorization of the board of directors, (i) receive in the form of a loan money or assets of the company; or (ii) use, for their own benefit or for the benefit of related parties, assets, services or credits of the company.

• The execution of agreements that involve at least 5% of the assets of the company with persons or entities related to directors, managers or shareholders that own, directly or indirectly, 10% of the share capital, requires the prior authorization of the board of directors (with no participation of the director involved in the transaction, if any).

• The execution of agreements with a party controlled by the company’s controlling shareholder requires the prior authorization of the board of directors and an evaluation of the terms of the transaction by an external independent company (audit companies or other to be determined by the Peruvian Securities Commission).

The external independent company that reviews the transaction should not be related to the parties involved therein, nor to directors, managers or shareholders that own at least 10% of the share capital of the company.

As a general policy, we do not enter into transactions with directors and executive officers on terms more favorable than what we would offer third parties. Any related party transaction we have entered into in the past has been in the ordinary course of business and on an arm’s length basis.

Article 32 of the internal regulations of our board of directors establishes a review procedure for identifying, approving and accounting for related party transactions. Related party transactions are defined as any transaction that exceeds US$50,000 entered into by and among our company and any shareholder that owns 1% or more of our company’s or of our subsidiaries’ outstanding shares, directors, senior executives and persons related to them. The Human Resource Management and Social Responsibility Committee is responsible for identifying, analyzing and approving each such transaction considering market conditions and potential benefits for us and the related party. For more information, see “Management.”

Related Party Transactions

The following set forth the related party transactions we have entered in 2010, 2011, 2012 and the first quarter of 2013:

DESCRIPTION OF OUR SHARE CAPITAL

Set forth below is certain information relating to our share capital, including brief summaries of certain material provisions of our by-laws, Peruvian Corporate Law and certain other laws and regulations of Peru, all as in effect as of the date hereof.

General

We are a publicly-held corporation under Peruvian Corporate Law and registered with the Public Registry of Corporations in Lima. We are currently listed on the Lima Stock Exchange.

Our by-laws provide that our principal corporate purposes are to engage in any and all activities related to the construction and real estate businesses; to provide services related to the mining and hydrocarbons industries; to participate in all stages of development of public services and other infrastructure concessions; and to provide management and corporate services to related and third parties. In addition, our company can realize investments and corporate transactions, including the acquisition, holding and transfer of securities of Peruvian and foreign companies.

Common Shares

As of June 30, 2013, we had 558,284,190 common shares outstanding. As of June 30, 2013, there were 1,281 owners of record of our common shares. Our common shares have a par value of S/.1.00 per share and have been fully subscribed and are fully paid. Our common shares are registered in the Securities Public Registry of the Peruvian Securities Commission and are listed on the Lima Stock Exchange.

Shareholders’ Liability

Under Peruvian Corporate Law, holders of our common shares cannot vote on matters with respect to which they have a conflict of interest.

Under Article 133 of the Peruvian Corporate Law, a shareholder must abstain from voting when faced with a conflict of interest. A resolution approved in disregard of this provision may be challenged under Article 139 of the Peruvian Corporate Law and the shareholders that participated in the determination in breach of this provision, if their vote was key in attaining the required majority, may be held jointly liable.

Redemption and Rights of Withdrawal

Under Article 200 of the Peruvian Corporate Law, holders of our common shares have redemption rights if: (i) we change our corporate purpose; (ii) a change occurs in the place of organization to a foreign country; or (iii) any transformation, merger or significant spin-off occurs with respect to our company.

Preemptive and Accretion Rights

If we increase our share capital, holders of our common shares have the right to subscribe to new common shares on a pro rata basis. Holders of common shares have preemptive rights in order to maintain their share interest in our share capital, unless the capital increase (i) results from a conversion of debt to common shares, (ii) is approved by shareholders representing at least 40% of the subscribed voting shares provided that the capital increase does not favor, directly or indirectly, certain shareholders to the detriment of others, or (iii) results from a corporate reorganization.

Shareholders who are in default of any payments relating to subscribed but unpaid shares may not exercise their preemptive rights.

209

Voting Rights and Dividends

Holders of common shares are entitled to one vote per share, with the exception of the election of the board of directors, where each holder is entitled to one vote per share per nominee. Each holder’s votes may be cast for a single nominee or distributed among the nominees at the holder’s discretion. To that effect, each of our common shares gives the holder the right to as many votes as there are directors to be elected. Shareholders may pool votes in favor of one person or distribute them among various persons. Those candidates for the board who receive the most votes are elected directors. Holders of common shares may attend and vote at shareholders’ meetings either in person or through a proxy.

Holders of common shares have the right to participate in the distribution of dividends and shareholder equity resulting from liquidation. Our by-laws do not establish a maximum time limit for the payment of the dividends. However, according to Article 232 of the Peruvian Corporate Law, the right to collect past-due dividends in the case of companies that are publicly held companies, such as ours, expires ten years after the date on which the dividend payment was due.

Our share capital may be increased by a decision of holders of common shares at a shareholders’ meeting. Capital reductions may be voluntary or mandatory and must be approved by holders of common shares at a shareholders’ meeting. Capital reductions are mandatory when accumulated losses exceed 50% of the capital and to the extent such accumulated losses are not offset by accumulated earnings and capital increases within the following fiscal year. Capital increases and reductions must be communicated to the Peruvian Securities Commission, the Lima Stock Exchange and SUNAT. Voluntary capital reductions must also be published in the official gazette El Peruano and in a widely circulated newspaper in the city in which we are located.

Liquidation Rights

If we are liquidated, our shareholders have the right to receive net assets resulting from the liquidation, after we comply with our obligation to pay all our creditors and after discounting any existing dividend liabilities. For this reason, we cannot assure that we will be able to reimburse 100% of the book value of the common shares in case of bankruptcy or liquidation.

Ordinary and Extraordinary Meetings

Pursuant to Peruvian Corporate Law and our by-laws, the annual shareholders’ meeting must be held during the three-month period after the end of each fiscal year. Additional shareholders’ meetings may be held during the year. Because we are a publicly-held corporation, we are subject to the special control of the Peruvian Securities Commission, as provided in Article 253 of the Peruvian Corporate Law. If we do not hold the annual shareholders’ meeting during the three-month period after the end of each fiscal year or any other shareholders’ meeting required by our by-laws, a public notary or a competent judge shall call for such a meeting at the request of at least one shareholder of the common shares. Such meeting will take place within a reasonable period of time.

Pursuant to the Peruvian Corporate Law, other shareholders’ meetings are convened by the board of directors when deemed convenient by the company or when it is requested by notarized letter by the holders of at least 5% of our common shares which voting rights are not suspended according to Peruvian Law. Pursuant to section 255 of the Peruvian Corporate Law, if the board expressly or implicitly refuses to convene the shareholders’ meeting, a notary public or a competent judge will call for such meeting at the request of holders of at least 5% of our common shares. If a notary public or competent judge calls for a shareholders’ meeting, the place, date and hour of the meeting, the agenda, the person who will preside the meeting and the notary public who will certify the resolutions of the meeting shall be indicated in the meeting notice. If the meeting called is other than the annual shareholders’ meeting or a shareholders’ meeting required by the Peruvian Corporate Law or the by-laws, the agenda will contain those matters requested by the shareholders who requested the meeting.

210

Notices of Meetings

Since we are a publicly-held corporation, notice of shareholders’ meetings must be given by publication of a notice. The publication shall occur at least 25 days prior to any shareholders’ meeting in the Peruvian Official Gazette, El Peruano, and in a widely circulated newspaper in the city in which we are located.

Quorum and Voting Requirements

According to Article 33 of our by-laws and Article 257 of the Peruvian Corporate Law, shareholders’ meetings called for the purpose of considering a capital increase or decrease, the issuance of obligations, a change in the by-laws, the sale in a single act of assets with an accounting value that exceeds 50% of our share capital, a merger, division, reorganization, transformation or dissolution, are subject to a first, second and third quorum call, with each of the second and third quorum call to occur upon the failure of the preceding one. A quorum for the first call requires the presence of shareholders holding 50% of our total common shares. For the second call, the presence of shareholders holding at least 25% of our total common shares is adequate, while for the third call there is no quorum requirement. These decisions require the approval of the majority of the common shares represented at the shareholders’ meeting. Shareholders’ meetings convened to consider all other matters are subject to a first and second quorum call, with the second quorum call to occur upon the failure of the first quorum.

In accordance with Peruvian Corporate Law, only those holders of common shares whose names are registered in the company’s stock ledger not less than 10 days in advance of a meeting will be entitled to attend the shareholders’ meeting and to exercise their rights.

Limitations on the Rights of Non-residents or Foreign Shareholders

There are no limitations under our by-laws or Peruvian Corporate Law on the rights of non-residents or foreign shareholders to own securities or exercise voting rights with respect to our securities.

Disclosure of Shareholdings and Tender Offer Regulations

Disclosure of Shareholdings

There are no provisions in our by-laws governing the ownership threshold above which share ownership must be disclosed.

However, according to Article 10 of CONASEV Resolution Nº 090-2005-EF-94.10, as amended, we must inform the Peruvian Securities Commission of the members of our economic group, comprised by our subsidiaries, and a list of our holders of common shares owning more than a 5% share interest, as well as any change to such information.

Tender Offer Regulations

Peruvian securities regulations include mandatory takeover rules applicable to the acquisition of control of a publicly held company.

Subject to certain conditions, such regulations generally establish the obligation to launch a tender offer when a person or group of persons acquires a significant interest in a publicly held company. According to the provisions set forth in CONASEV Resolution No. 009-2006-EF-94.10, a person acquires a significant interest in a listed company when such person (a) holds or has the power to exercise directly or indirectly 25%, 50% or 60% of the voting rights in a listed company, or (b) has the power to appoint or remove the majority of the board members or to amend its by-laws.

211

A tender offer may be launched prior or following an acquisition of the significant interest. The tender offer may be launched after the “significant interest” is acquired if it is acquired (a) by means of an indirect transaction, defined as a relevant acquisition or interest increase through the acquisition of securities issued by a company that in turn holds share capital of the target company; (b) as a consequence of a public sale offer, or (c) in no more than four transactions within a three-year period.

This mandatory procedure has the effect of alerting other shareholders and the market that an individual or financial group has acquired a significant percentage of a company’s voting shares, and gives other shareholders the opportunity to sell their shares at the price offered by the purchaser. The purchaser is required to launch a tender offer unless: (a) shareholders representing 100% of the voting rights consent in writing, (b) voting shares are acquired by a depositary in order to subsequently issue ADSs, or (c) voting shares are acquired pursuant to the exercise of preemptive rights.

Changes in Capital

Our by-laws do not establish special conditions to increase or reduce our share capital beyond what is required under Peruvian Corporate Law.

Anti-Takeover Provisions

Our by-laws do not contain any provision that would have the effect of delaying, deferring or preventing a change of control.

Form and Transfer

Common shares may be either physical share certificates in registered form or book-entry securities in the CAVALI S.A. ICLV book-entry settlement system also in registered form. Furthermore, in the case of shares represented in book entries, the issuance of new shares which result from share splits or similar corporate events must also be represented in said form.

Furthermore, the Peruvian Corporate Law forbids publicly-held corporations, such as us, from including in their by-laws stipulations limiting the transfer of their shares or restraining their trading in other ways. According to Article 18 of our by-laws, we cannot recognize a shareholders’ agreement that contemplates limitations, restrictions or preferential rights on the transfer of shares, even if such an agreement is recorded in our stock ledger (matrícula de acciones) or in CAVALI. As of the date of this offering, no shareholders’ agreement is recorded in our stock ledger.

Arbitration

Our by-laws include an arbitration clause applicable to disputes arising from the interpretation of our by-laws or Peruvian Corporate Law and their complementary provisions, among our company, our management and our shareholders. Any such arbitration will be subject to the regulations of the Arbritration Center of the Lima Chamber of Commerce. The material terms of the arbitration clause are as follows:

• any dispute, controversy or claim arising out of the performance and the interpretation of the by-laws and any action or remedy set forth in the Peruvian Corporate Law (Ley General de Sociedades) among us, our current or former shareholders and/or our current or former management shall be settled by arbitration;

• any dispute, controversy or claim between us and a third party shall be also settled by arbitration, if agreed upon by all parties either expressly or tacitly;

• arbitrations shall be conducted before a panel of three arbitrators;

212

• arbitrators shall consider only the applicable law for their award (arbitration in law and not arbitration in equity);

• each party to a dispute shall appoint an arbitrator within 10 business days from receiving the notice of arbitration. The two selected arbitrators shall appoint the third arbitrator. If one of the parties fails to appoint its arbitrator within 10 business days, the Center of Arbitration of the Lima Chamber of Commerce shall appoint the arbitrator;

• the rules of the Center of Arbitration of the Lima Chamber of Commerce shall apply to the arbitration; and

• the arbitration clause is not applicable to the cases that must be submitted to the jurisdiction of the courts or of the Superintendencia del Mercado de Valores, such as when arbitration would present hardship to minority shareholders or when Peruvian law otherwise requires it.

The arbitration clause does not apply to claims based on violations of U.S. securities laws in connection with this offering, unless agreed by the parties to a claim. Our Peruvian Counsel, Muñiz, Ramirez, Perez-Taiman & Olaya Abogados, has provided us with their opinion to that effect.

213

DIVIDENDS

Dividend Policy

Our current dividend policy, adopted on March 26, 2013, is to distribute between 30% and 40% of the net profit from the preceding year. Holders of our common shares are entitled to receive dividends on a pro rata basis in accordance with their respective number of shares held. Our dividend policy can be modified by a favorable vote of a majority of our shareholders and any changes become effective 30 days after approval.

Article 23 of our by-laws establishes that dividends distribution must be approved by our shareholders during the annual shareholders’ meeting. The recommendation of our board of directors is required for the distribution of interim dividends, which must be subsequently ratified at a shareholders’ meeting.

Under Peruvian law, companies may distribute up to 100% of their profit (after payment of income tax) subject to a 10% legal reserve until the legal reserve equals 20% of shareholders’ equity. According to Article 40 of the Peruvian Corporate Law, in order to distribute dividends, profits must be determined in accordance with the individual financial statements of the company.

Payment of Dividends

Dividends are paid to holders of our common shares as of a record date determined by us. In order to allow for the settlement of securities, under the rules of the Peruvian Securities Commission, investors who purchase shares of a publicly-held company three business days prior to a dividend payment date do not have the right to receive such dividend payment. Dividends on issued and outstanding common shares are distributed pro rata.

Our syndicated loan agreement contains certain customary covenants, including restrictions on our ability to pay dividends if we are in default under the agreement. Our subsidiaries have also agreed to limitations on their ability to pay dividends based on compliance with certain financial ratios. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Indebtedness.”

Holders of common shares are not entitled to interest on accrued dividends. In addition, under Article 232 of the Peruvian Corporate Law, the right to collect accrued dividends declared by a publicly-held company expires ten years from the original dividend payment date.

Regulation of the Peruvian Securities Market

The regulatory framework for the Peruvian securities market is established in the Securities Market Law approved by Legislative Decree No. 861, whose unified sole text was enacted by Supreme Decree No. 093-2002-EF, as amended (Ley del Mercado de Valores), and the resolutions issued from time to time by the Peruvian Securities Commission. The purpose of the Securities Market Law is to promote the ordered development and transparency of the securities markets, adequate protection for investors and the principles under which the Peruvian securities market is intended to operate. The Securities Market Law contains the general rules for: (i) primary and secondary public offerings of securities; (ii) public offering of securities for acquisitions; (iii) local and international offerings, including simultaneous offerings; (iv) the Public Registry of Securities (the Registro Público del Mercado de Valores); (v) reporting obligations of material information (hechos de importancia) by the issuers of securities recorded in the Public Registry of Securities and by the

217

entities that are subject to the regulation and supervision of the Peruvian Securities Commission; (vi) the enforcement of insider trading; (vii) privileged information and confidentiality regulations and prohibitions against price manipulation, (viii) the broker-dealers; (ix) the Lima Stock Exchange; (x) CAVALI (the settlement and registry entity for transactions executed on the Lima Stock Exchange); (xi) other entities that are required to be registered at the Public Registry of Securities; (xii) capital market instruments and operations, including securitizations; and (xiii) mutual funds and investments funds publicly placed and their respective management companies.

The Peruvian securities market is regulated and supervised by the Peruvian Securities Commission, a governmental entity reporting to the Peruvian Ministry of Economy and Finance, with functional, administrative, economic, technical and budgetary autonomy. The Peruvian Securities Commission is governed by the Superintendent, designated by the Peruvian Ministry of Economy and Finance, and by a five member board of directors convened by the Superintendent (who acts as Chairman of the board). The other four members are appointed by the government under applicable legislation. The Peruvian Securities Commission issues from time to time resolutions which provide specific regulations or may impose sanctions in cases of violations of the Securities Market Law or the resolutions issued by the Peruvian Securities Commission.

The Peruvian Securities Commission, in order to achieve the Securities Market Law´s purposes, has broad regulatory and supervisory powers, including (i) issuing general mandatory rules; (ii) supervision and oversight of compliance with applicable legislation (including the power to order inspections and require the submission of information and documentation by entities that are under its jurisdiction and summon and interrogate any person that may contribute to its investigations); (iii) imposing sanctions; (iv) managing the Public Registry of Securities; (v) authorizing public offerings of securities and the recording at the Public Registry of Securities that may be the subject of such public offerings and the respective programs for issuances; (vi) authorizing the incorporation and functioning of entities under its scope of supervision; and (vii) monitoring the content and accuracy of the financial and other information that is filed with the Peruvian Securities Commission. The Peruvian Securities Commission is responsible for the enactment, interpretation and enforcement of rules and regulations issued under the Securities Market Law.

Disclosure Obligations

Issuers of securities registered with the Peruvian Securities Commission are required to disclose material information relating to the issuer. Pursuant to the Securities Market Law and relevant regulations enacted thereunder, all material information in connection with the issuer of registered securities (such as our common shares), its activities or securities issued or secured by such issuer which may influence the liquidity or price of such securities must be disclosed. Accordingly, issuers must file with the Peruvian Securities Commission mainly two types of information: (a) financial information, including unaudited interim financial statements on a quarterly basis (which are not required to be subject to limited review by external auditors), and audited annual consolidated financial statements on an annual basis, and (b) material information relating to the issuer and its activities that may significantly affect the price, offering or trading of the issued securities, and in general, all the information that may be relevant for investors to be able to make investment decisions.

In order to comply with the foregoing disclosure obligations, issuers must disclose information to the Peruvian Securities Commission and, if the securities are listed, with the Lima Stock Exchange as soon as practicable but not later than one business day after having become aware of such information.

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

General

JPMorgan Chase Bank, N.A., as depositary, will issue the ADSs which you will be entitled to receive in this offering. Each ADS will represent an ownership interest in five common shares which we will deposit with the custodian, Citibank del Perú S.A., as agent of the depositary, under the deposit agreement among us, the depositary and you as an ADS holder. In the future, each ADS will also represent any securities, cash or other property deposited with the depositary but which they have not distributed directly to you. Unless certificated ADRs are specifically requested by you, all ADSs will be issued on the books of our depositary in book-entry form and periodic statements will be mailed to you which reflect your ownership interest in such ADSs. In this description, references to ADRs, shall include the statements you will receive which reflect your ownership of ADSs.

The depositary’s office is located at 1 Chase Plaza, Floor 58, New York, New York 10005-1401, United States.

You may hold ADSs either directly or indirectly through your broker or other financial institution. If you hold ADSs directly, by having an ADS registered in your name on the books of the depositary, you are an ADR holder. This description assumes you hold your ADSs directly. If you hold the ADSs through your broker or financial institution nominee, you must rely on the procedures of such broker or financial institution to assert the rights of an ADR holder described in this section. You should consult with your broker or financial institution to find out what those procedures are.

As an ADR holder, we will not treat you as a shareholder of ours and you will not have any shareholder rights. Peruvian law governs shareholder rights. ADR holders have no direct ownership interest in our common shares and only have such rights as specified in the deposit agreement. Your rights are those of an ADR holder. Such rights derive from the terms of the deposit agreement to be entered into among us, the depositary and all registered holders from time to time of ADSs issued under the deposit agreement. The obligations of the depositary and its agents are also set out in the deposit agreement. Because the depositary or its nominee will actually be the registered owner of the common shares, you must rely on the depositary or its nominee to exercise the rights of a shareholder on your behalf. The deposit agreement and the ADSs are governed by the law of the State of New York. However, our obligations to the holders of common shares represented by the ADSs will continue to be governed by the laws of Peru, which may be different from the law of the State of New York.

The following is a summary of what we believe to be the material terms of the deposit agreement. This summary is qualified in its entirety by reference to, and should be read in conjunction with, the entire deposit agreement and the form of ADR which contains the complete terms of your ADSs. You can read a copy of the deposit agreement, a form of which is filed as exhibit 4.2 to the registration statement of which this prospectus forms a part. You may also obtain a copy of the deposit agreement at the SEC’s Public Reference Room which is located at 100 F Street, NE, Washington, DC 20549, United States. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-732-0330. You may also find the registration statement and the attached deposit agreement on the SEC’s website at http://www.sec.gov.

Dividends and Other Distributions

We may make various types of distributions with respect to our securities. The depositary has agreed that, to the extent practicable, it will pay to you the cash dividends or other distributions it or the custodian receives on common shares or other deposited securities, after converting any cash received into U.S. dollars and, in all cases, making any necessary deductions provided for in the deposit agreement. You will receive these distributions in proportion to the number of underlying securities that your ADSs represent.

219

Except as stated below, the depositary will deliver such distributions to ADR holders in proportion to their interests in the following manner:

Distribution of Cash. The depositary will distribute any U.S. dollars available to it resulting from a cash dividend or other cash distribution or the net proceeds of sales of any other distribution or portion thereof (to the extent applicable), on an averaged or other practicable basis, subject to (i) appropriate adjustments for taxes withheld, (ii) such distribution being impermissible or impracticable with respect to certain registered ADR holders, and (iii) deduction of the depositary’s and/or its agents’ expenses in (1) converting any foreign currency to U.S. dollars to the extent that it determines that such conversion may be made on a reasonable basis, (2) transferring foreign currency or U.S. dollars to the United States by such means as the depositary may determine to the extent that it determines that such transfer may be made on a reasonable basis, (3) obtaining any approval or license of any governmental authority required for such conversion or transfer, which is obtainable at a reasonable cost and within a reasonable time, and (4) making any sale by public or private means in any commercially reasonable manner. If exchange rates fluctuate during a time when the depositary cannot convert a foreign currency, you may lose some or all of the value of the distribution.

Distribution of Common Shares. In the case of a distribution of common shares, the depositary will issue additional ADRs to evidence the number of ADSs representing such common shares. Only whole ADSs will be issued. Any common shares which would result in fractional ADSs will be sold and the net proceeds will be distributed in the same manner as cash to the ADR holders entitled thereto.

No distribution of ADRs as described above will be made if it violates U.S. securities laws, or any other law, or if it is not operationally practicable. If the depositary does not distribute new ADRs as described above, it will use its best efforts to sell the common shares received and distribute the proceeds of the sale in the same manner as a cash distribution.

Rights to Receive Additional Common Shares. In the case of a distribution of rights to subscribe for additional common shares or other rights, if we provide evidence satisfactory to the depositary that it may lawfully distribute such rights, the depositary will distribute warrants or other instruments in the discretion of the depositary representing such rights. If we do not furnish such evidence, the depositary may:

• sell such rights if practicable and distribute the net proceeds in the same manner as cash distributions to the ADR holders entitled thereto; or

• if the sale of such rights cannot practicably be accomplished by reason of the non-tranferability of the rights, limited markets therefor, their short duration or otherwise, do nothing and allow such rights to lapse, in which case ADR holders will receive nothing.

Other Distributions. In the case of a distribution of securities or property other than those described above, the depositary may either (i) distribute such securities or property in any manner it deems equitable and practicable or (ii) to the extent the depositary deems distribution of such securities or property not to be equitable and practicable, sell such securities or property and distribute any net proceeds in the same manner it distributes cash. If the depositary determines that any distribution described above is not practicable with respect to any specific registered ADR holder, the depositary may choose any method of distribution that it deems practicable for such ADR holder, including the distribution of foreign currency, securities or property, or it may retain such items, without paying interest on or investing them, on behalf of the ADR holder as deposited securities, in which case the ADSs will also represent the retained items.

U.S. dollars will be distributed by checks drawn on a bank in the United States for whole U.S. dollars and cents. Fractional cents will be withheld without liability and dealt with by the depositary in accordance with its then current practices.

We have no obligation to file a registration statement under the Securities Act in order to make any rights , securities or other property available to ADR holders.

220

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADR holders.

The depositary may use a division, branch or affiliate of JPMorgan Chase Bank, N.A. to direct manage and/or execute any public and/or private sale of securities.

There can be no assurance that the depositary will be able to convert any currency at a specified exchange rate or sell any property, rights, common shares or other securities at a specified price, nor that any of such transactions can be completed within a specified time period.

Issuance of ADSs upon Deposit of Common Shares

The depositary will issue ADSs if you or your broker deposit common shares or evidence of rights to receive common shares with the custodian and pay the fees and expenses owing to the depositary in connection with such issuance. In the case of the ADSs to be issued under this prospectus, we will deposit such common shares.

Common shares deposited in the future with the custodian must be accompanied by the delivery of certain documentation and shall, at the time of such deposit, be registered in the name of JPMorgan Chase Bank, N.A., as depositary for the benefit of holders of ADRs or in such other name as the depositary shall direct.

The custodian will hold all deposited common shares (including those being deposited by us or on our behalf in connection with the offering to which this prospectus relates) for the account of the depositary. ADR holders thus have no direct ownership interest in our common shares and only have such rights as are contained in the deposit agreement. The custodian will also hold any additional securities, property and cash received on or in substitution for the deposited common shares. The deposited common shares and any such additional items are referred to as “deposited securities.”

Upon each deposit of common shares, receipt of related documentation and compliance with the other provisions of the deposit agreement, including the payment of the fees and charges of the depositary and any taxes or other fees or charges owing, the depositary will issue an ADR or ADRs in the name or upon the order of the person entitled thereto evidencing the number of ADSs to which such person is entitled. All of the ADSs issued will, unless specifically requested to the contrary, be part of the depositary’s direct registration system, and a registered holder will receive periodic statements from the depositary which will show the number of ADSs registered in such holder’s name. An ADR holder can request that the ADSs not be held through the depositary’s direct registration system and that a certificated ADR be issued.

The term common shares in this section shall also refer to preliminary stock certificates (certificados provisionales), which will be converted to common shares once the capital increase is registered with the Peruvian public registry and new common shares are listed on the Lima Stock Exchange and registered in the CAVALI S.A. ICLV book-entry settlement system.

Withdrawal of Common Shares upon Cancellation of ADSs

When you turn in your ADR certificate at the depositary’s office, or when you provide proper instructions and documentation in the case of direct registration ADSs, the depositary will, upon payment of certain applicable fees, charges and taxes, deliver the underlying common shares to you upon your written order. Delivery of common shares in certificated form will be made at the custodian’s office. At your risk, expense and request, the depositary may deliver deposited securities at such other place as you may request.

The depositary may only restrict the withdrawal of deposited securities in connection with:

• temporary delays caused by closing our transfer books or those of the depositary or the deposit of common shares in connection with voting at a shareholders’ meeting, or the payment of dividends;

221

• the payment of fees, taxes and similar charges; or

• compliance with any Peruvian, U.S. or other foreign laws or governmental regulations relating to the ADRs or to the withdrawal of deposited securities.

Notwithstanding the foregoing, no withdrawal of deposited securities shall be permitted until the preliminary stock certificates (certificados provisionales) have been converted to common shares once the capital increase has been recorded with the Peruvian public registry.

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Record Dates

The depositary may, after consultation with us if practicable, fix record dates for the determination of the registered ADR holders who will be entitled (or obligated, as the case may be) to:

• receive any distribution on or in respect of common shares;

• give instructions for the exercise of voting rights at a meeting of holders of common shares;

• pay the fee assessed by the depositary for administration of the ADR program and for any expenses as provided for in the ADR; or

• receive any notice or to act in respect of any other matter, in each case, subject to the provisions of the deposit agreement.

Voting Rights

A holder of an ADR representing common shares will generally have the right under the deposit agreement to instruct the depositary to exercise the voting rights for the underlying common shares represented by such ADRs. The voting rights of holders of common shares are described under “Description of our Share Capital.”

If you are an ADR holder and the depositary asks you to provide it with voting instructions, you may instruct the depositary how to exercise the voting rights for the common shares which underlie your ADSs. As soon as practicable after receiving notice of any meeting or solicitation of consents or proxies from us, the depositary will distribute to the registered ADR holders a notice stating such information as is contained in the voting materials received by the depositary and describing how you may instruct the depositary to exercise the voting rights for the common shares which underlie your ADSs, including instructions for giving a discretionary proxy to a person designated by us. For instructions to be valid, the depositary must receive them in the manner and on or before the date specified. The depositary will try, as far as is practical, subject to the provisions of and governing the underlying common shares or other deposited securities and Peruvian law, to vote or to have its agents vote the common shares or other deposited securities as you instruct. The depositary will only vote or attempt to vote as you instruct. The depositary will not itself exercise any voting discretion. Furthermore, neither the depositary, nor its agents, are responsible for any failure to carry out any voting instructions, for the manner in which any vote is cast or for the effect of any vote, other than for failure caused directly by gross negligence, bad faith or willful misconduct on the part of the depositary or its agents. Notwithstanding anything contained in the deposit agreement or any ADR, the depositary may, to the extent not prohibited by law or applicable regulations, or by the requirements of the stock exchange on which the ADSs are listed, in lieu of distribution of the materials provided to the depositary in connection with any meeting of, or solicitation of consents or proxies from, holders of deposited securities, distribute to the registered holders of ADRs a notice that provides such holders with, or otherwise publicizes to such holders, instructions on how to retrieve such materials or receive such materials upon request (i.e., by reference to a website containing the materials for retrieval or a contact for requesting copies of the materials).

There is no assurance that you will receive voting materials in time to instruct the depositary to vote and it is possible that you, or persons who hold their ADSs through brokers, dealers or other third parties, will not have the opportunity to exercise a right to vote.

222

Reports and Other Communications

The depositary will make available for inspection by ADR holders at the offices of the depositary and the custodian the deposit agreement, the provisions of or governing deposited securities, and any written communications from us which are both received by the custodian or its nominee as a holder of deposited securities and made generally available to the holders of deposited securities.

Additionally, if we make any written communications generally available to holders of our common shares, and we furnish copies thereof (or English translations or summaries) to the depositary, it will distribute the same to registered ADR holders.

Fees and Expenses

The depositary may charge each person to whom ADSs are issued, including, without limitation, issuances against deposits of common shares, issuances in respect of common share distributions, rights and other distributions, issuances pursuant to a stock dividend or stock split declared by us or issuances pursuant to a merger, exchange of securities or any other transaction or event affecting the ADSs or deposited securities, and each person surrendering ADSs for withdrawal of deposited securities or whose ADRs are cancelled or reduced for any other reason, US$5.00 or less for each 100 ADSs (or any portion thereof) issued, delivered, reduced, cancelled or surrendered, as the case may be. The depositary may sell (by public or private sale) sufficient securities and property received in respect of a common share distribution, rights and/or other distribution prior to such deposit to pay such charge.

The following additional charges shall be incurred by the ADR holders, by any party depositing or withdrawing common shares or by any party surrendering ADSs or to whom ADSs are issued (including, without limitation, issuance pursuant to a stock dividend or stock split declared by us or an exchange of stock regarding the ADRs or the deposited securities or a distribution of ADSs), whichever is applicable:

• a fee of US$1.50 per ADR or ADRs for transfers of certificated or direct registration ADRs;

• a fee of US$0.05 or less per ADS for any cash distribution made pursuant to the deposit agreement;

• a fee of US$0.05 or less per ADS per calendar year (or portion thereof) for services performed by the depositary in administering the ADRs (which fee may be charged on a periodic basis during each calendar year and shall be assessed against holders of ADRs as of the record date or record dates set by the depositary during each calendar year and shall be payable in the manner described in the next succeeding provision);

• a fee for the reimbursement of such fees, charges and expenses as are incurred by the depositary and/or any of the depositary’s agents (including, without limitation, the custodian and expenses incurred on behalf of holders in connection with compliance with foreign exchange control regulations or any law or regulation relating to foreign investment) in connection with the servicing of the common shares or other deposited securities, the sale of securities, the delivery of deposited securities or otherwise in connection with the depositary’s or the custodian’s compliance with applicable law, rule or regulation (which charge shall be assessed on a proportionate basis against holders as of the record date or dates set by the depositary and shall be payable at the sole discretion of the depositary by billing such holders or by deducting such charge from one or more cash dividends or other cash distributions);

• a fee for the distribution or sale of securities pursuant to paragraph 10 of the deposit agreement, such fee being in an amount equal to the US$0.05 per ADS issuance fee for the execution and delivery of ADSs which would have been charged as a result of the deposit of such securities (treating all such securities as if they were common shares) but which securities or the net cash proceeds from the sale thereof are instead distributed by the depositary to those holders entitled thereto;

• stock transfer or other taxes and other governmental charges;

223

• cable and facsimile transmission and delivery charges incurred at your request in connection with the deposit or delivery of common shares;

• transfer or registration fees for the registration of transfer of deposited securities on any applicable register in connection with the deposit or withdrawal of deposited securities; and

• expenses of the depositary in connection with the conversion of foreign currency into U.S. dollars.

We will pay all other charges and expenses of the depositary and any agent of the depositary (except the custodian) pursuant to agreements from time to time between us and the depositary. The charges described above may be amended from time to time by agreement between us and the depositary.

Our depositary has agreed to reimburse us for certain expenses we incur that are related to establishment and maintenance of the ADR program, including investor relations expenses and exchange application and listing fees. The amounts of reimbursements available to us are not based upon the amounts of fees the depositary collects from investors. The depositary collects its fees for issuance and cancellation of ADSs directly from investors depositing common shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting on their behalf. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions, or by directly billing investors, or by charging the book-entry system accounts of participants acting for them. The depositary will generally set off the amounts owing from distributions made to holders of ADSs. If, however, no distribution exists and payment owing is not timely received by the depositary, the depositary may refuse to provide any further services to holders that have not paid those fees and expenses owing until such fees and expenses have been paid. At the discretion of the depositary, all fees and charges owing under the deposit agreement are due in advance and/or when declared owing by the depositary.

Payment of Taxes

ADS holders or ADR holders, as the case may be, must pay any tax or other governmental charge (including any penalties and/or interest) payable by the custodian or the depositary on any ADS or ADR, deposited security or distribution. By holding or having held an ADS or an ADR, as the case be, the holders agree to indemnify, defend and save harmless each of the depositary and its agents in respect thereof. If an ADS holder or ADR holder, as the case may be, owes any tax or other governmental charge, the depositary may (i) deduct the amount thereof from any cash distributions, or (ii) sell deposited securities (by public or private sale) and deduct the amount owing from the net proceeds of such sale. In either case the ADS holder or ADR holder, as the case may be, remains liable for any shortfall. If any tax or governmental charge is unpaid, the depositary may also refuse to effect any registration, registration of transfer, split up or combination of deposited securities or withdrawal of deposited securities until such payment is made. If any tax or governmental charge is required to be withheld on any cash distribution, the depositary may deduct the amount required to be withheld from any cash distribution or, in the case of a non-cash distribution, sell the distributed property or securities (by public or private sale) to pay such taxes and distribute any remaining net proceeds to the ADS holders or the ADR holders entitled thereto.

By holding an ADR or an ADS, as the case may be, or an interest therein, you will be agreeing to indemnify us, the depositary, the custodian and any of our or their respective directors, employees, agents and affiliates against, and hold each of them harmless from, any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced rate of withholding at source or other tax benefit obtained.

224

Reclassifications, Recapitalizations and Mergers

If we take certain actions that affect the deposited securities, including (i) any change in par value, split up, consolidation, cancellation or other reclassification of deposited securities or (ii) any distributions not made to holders of ADRs or (iii) any recapitalization, reorganization, merger, consolidation, liquidation, receivership, bankruptcy or sale of all or substantially all of our assets, then the depositary may choose to:

• amend the form of ADR;

• distribute additional or amended ADRs;

• distribute cash, securities or other property it has received in connection with such actions;

• sell any securities or property received and distribute the proceeds as cash; or

• none of the above.

If the depositary does not choose any of the above options, any of the cash, securities or other property it receives will constitute part of the deposited securities and each ADS will then represent a proportionate interest in such property.

Amendment and Termination

We may agree with the depositary to amend the deposit agreement and the ADSs without your consent for any reason. ADR holders must be given at least 30 days’ notice of any amendment that imposes or increases any fees or charges (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, cable, telex or facsimile transmission costs, delivery costs or other such expenses), or otherwise prejudices any substantial existing right of ADR holders. Such notice need not describe in detail the specific amendments effectuated thereby, but must give ADR holders a means to access the text of such amendment. If an ADR holder continues to hold an ADR or ADRs after being so notified, such ADR holder is deemed to agree to such amendment and to be bound by the deposit agreement as so amended. Notwithstanding the foregoing, if any governmental body or regulatory body should adopt new laws, rules or regulations which would require amendment or supplement of the deposit agreement or the form of ADR to ensure compliance therewith, we and the depositary may amend or supplement the deposit agreement and the ADR at any time in accordance with such changed laws, rules or regulations, which amendment or supplement may take effect before a notice is given or within any other period of time as required for compliance. No amendment, however, will impair your right to surrender your ADSs and receive the underlying securities, except in order to comply with mandatory provisions of applicable law.

The depositary may, and shall at our written direction, terminate the deposit agreement and the ADRs by mailing notice of such termination to the registered holders of ADRs at least 30 days prior to the date fixed in such notice for such termination; provided, however, if the depositary shall have (1) resigned as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders unless a successor depositary shall not be operating under the deposit agreement within 60 days of the date of such resignation, and (2) been removed as depositary under the deposit agreement, notice of such termination by the depositary shall not be provided to registered holders of ADRs unless a successor depositary shall not be operating under the deposit agreement on the 60th day after our notice of removal was first provided to the depositary. After termination, the depositary’s only responsibility will be (1) to deliver deposited securities to ADR holders who surrender their ADRs, and (2) to hold or sell distributions received on deposited securities. As soon as practicable after the expiration of six months from the termination date, the depositary will sell the deposited securities which remain and hold the net proceeds of such sales (as long as it may lawfully do so), without liability for interest, in trust for the ADR holders who have not yet surrendered their ADRs. After making such sale, the depositary shall have no obligations except to account for such proceeds and other cash.

225

Limitations on Obligations and Liability to ADR Holders

Prior to the issue, registration, registration of transfer, split-up, combination, or cancellation of any ADRs, or the delivery of any distribution in respect thereof, and from time to time, we or the depositary or the custodian may require:

• payment with respect thereto of (i) any stock transfer or other tax or other governmental charge, (ii) any stock transfer or registration fees in effect for the registration of transfers of common shares or other deposited securities upon any applicable register and (iii) any applicable fees and expenses described in the deposit agreement;

• the production of proof satisfactory to it of (i) the identity of any signatory and genuineness of any signature and (ii) such other information, including without limitation, information as to citizenship, residence, exchange control approval, beneficial ownership of any securities, compliance with applicable law, regulations, provisions of or governing deposited securities and terms of the deposit agreement and the ADRs, as it may deem necessary or proper; and

• compliance with such regulations as the depositary may establish consistent with the deposit agreement.

The issuance of ADRs, the acceptance of deposits of common shares, the registration, registration of transfer, split-up or combination of ADRs or the withdrawal of common shares, may be suspended, generally or in particular instances, when the ADR register or any register for deposited securities is closed or when any such action is deemed advisable by the depositary or when reasonably requested by us in order to enable us to comply with applicable law; provided that the ability to withdraw common shares may only be limited under the following circumstances: (i) temporary delays caused by closing transfer books of the depositary or our transfer books or the deposit of common shares in connection with voting at a shareholders’ meeting, or the payment of dividends, (ii) the payment of fees, taxes, and similar charges, and (iii) compliance with any laws or governmental regulations relating to ADRs or to the withdrawal of deposited securities.

The deposit agreement expressly limits the obligations and liability of the depositary, ourselves and our respective agents. Neither we nor the depositary nor any such agent will be liable if:

• any present or future law, rule, regulation, fiat, order or decree of the United States, Peru or any other country, or of any governmental or regulatory authority or securities exchange or market or automated quotation system, the provisions of or governing any deposited securities, any present or future provision of our charter, any act of God, war, terrorism, nationalization, expropriation, currency restrictions, work stoppage, strike, civil unrest, revolutions, rebellions, explosions, computer failure or other circumstance beyond our, the depositary’s or our respective agents’ control shall prevent or delay, or shall cause any of them to be subject to any civil or criminal penalty in connection with, any act which the deposit agreement or the ADRs provide shall be done or performed by us, the depositary or our respective agents (including, without limitation, voting);

• it exercises or fails to exercise discretion under the deposit agreement or the ADRs issued thereunder including, without limitation, any failure to determine that any distribution or action may be lawful or reasonably practicable;

• it performs its obligations under the deposit agreement and ADRs issued thereunder without gross negligence, bad faith or willful misconduct;

• it takes any action or refrains from taking any action in reliance upon the advice of or information from legal counsel, accountants, any person presenting common shares for deposit, any registered holder of ADRs, or any other person believed by it to be competent to give such advice or information; or

• it relies upon any written notice, request, direction, instruction or document believed by it to be genuine and to have been signed presented or given by the proper party or parties.

226

Neither the depositary nor its agents have any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADRs. We and our agents shall only be obligated to appear in, prosecute or defend any action, suit or other proceeding in respect of any deposited securities or the ADRs, which in our opinion may involve us in expense or liability, if indemnity satisfactory to us against all expense (including fees and disbursements of counsel) and liability is furnished as often as may be required. The depositary and its agents may fully respond to any and all demands or requests for information maintained by or on its behalf in connection with the deposit agreement, any registered holder or holders of ADRs, any ADRs or otherwise related to the deposit agreement or ADRs to the extent such information is requested or required by or pursuant to any lawful authority, including, without limitation, laws, rules, regulations, administrative or judicial processes, banking, securities or other regulators. The depositary shall not be liable for the acts or omissions made by, or the insolvency of any securities depository, clearing agency or settlement system in connection with or arising out of book-entry settlement of deposited securities or otherwise. Furthermore, the depositary shall not be responsible for, and shall incur no liability in connection with or arising from, the insolvency of any custodian that is not a branch or affiliate of JPMorgan Chase Bank, N.A. The depositary and the custodian may use third party delivery services and providers of information regarding matters such as pricing, proxy voting, corporate actions, class action litigation and other services in connection with the ADRs and the deposit agreement, and use local agents to provide extraordinary services such as attendance at annual meetings of issuers of securities. The depositary and the custodian are required to use reasonable care in the selection and retention of such third party providers and local agents, but neither the depositary nor the custodian will be responsible for any error or omissions made by such third party providers or local agents in providing the relevant information or services. The depositary shall not be responsible for, and shall incur no liability in connection with or arising from, any act or omission to act on the part of the custodian except to the extent that (A) the custodian has been determined by a final non-appealable judgment of a court of competent jurisdiction to have (i) committed fraud or willful misconduct in the provision of custodial services to the depositary or (ii) failed to use reasonable care in the provision of custodial services to the depositary as determined in accordance with the standards prevailing in the jurisdiction in which the custodian is located and (B) we or the registered holders of ADRs have incurred direct damages as a result of such act or omission to get on the part of the custodian.

The depositary shall be under no obligation to inform holders of ADSs regarding the requirements of Peruvian law, rules or regulations or any changes therein or thereunder.

Additionally, none of us, the depositary or the custodian will be liable for the failure by any registered holder of ADRs or beneficial owner therein to obtain the benefits of credits on the basis of non-U.S. tax paid against such holder’s or beneficial owner’s income tax liability. Neither we nor the depositary shall incur any liability for any tax consequences that may be incurred by holders or beneficial owners on account of their ownership of ADRs or ADSs.

The depositary shall not incur any liability for the content of any information submitted to it by us or on our behalf for distribution to the holders of ADRs or for any inaccuracy of any translation thereof, for any investment risk associated with acquiring an interest in the deposited securities, for the validity or worth of the deposited securities, for the credit-worthiness of any third party, for allowing any rights to lapse upon the terms of the deposit agreement or for the failure or timeliness of any notice from us. Further, the depositary shall not have any liability for the price received in connection with any sale of securities or the timing thereof.

Neither the depositary nor its agents will be responsible for any failure to carry out any instructions to vote any of the deposited securities, for the manner in which any such vote is cast or for the effect of any such vote. None of us, the depositary, or our agents shall be liable to registered holders of ADRs or beneficial owners of interests in ADSs for any indirect, special, punitive or consequential damages (including, without limitation, lost profits) of any form incurred by any person or entity, whether or not foreseeable and regardless of the type of action in which such a claim may be brought.

227

The depositary shall not be liable for any acts or omissions made by a successor depositary whether in connection with a previous act or omission of the depositary or in connection with any matter arising wholly after the removal or resignation of the depositary, provided that in connection with the issue out of which such potential liability arises the depositary performed its obligations without negligence while it acted as depositary.

In the deposit agreement each party thereto (including, for avoidance of doubt, each holder and beneficial owner and/or holder of interests in ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any suit, action or proceeding against the depositary and/or us directly or indirectly arising out of or relating to the common shares or other deposited securities, the ADSs or the ADRs, the deposit agreement or any transaction contemplated therein, or the breach thereof (whether based on contract, tort, or common law or any other theory).

The depositary may rely upon instructions from us or our counsel in respect of any governmental or agency approval or license required for any currency conversion, transfer or distribution.

The depositary may own and deal in any class of our securities and in ADSs.

Disclosure of Interest in ADSs

To the extent that the provisions of, or governing, any deposited securities may require disclosure of or impose limits on beneficial or other ownership of deposited securities, other common shares and other securities and may provide for blocking transfer, voting or other rights to enforce such disclosure or limits, you agree to comply with all such disclosure requirements and ownership limitations and to comply with any reasonable instructions we may provide in respect thereof. We reserve the right to instruct you to deliver your ADSs for cancellation and withdrawal of the deposited securities so as to permit us to deal with you directly as a holder of common shares and, by holding an ADS or an interest therein, you will be agreeing to comply with such instructions.

Books of Depositary

The depositary or its agent will maintain a register for the registration, registration of transfer, combination and split-up of ADRs, which register shall include the depositary’s direct registration system. Registered holders of ADRs may inspect such records at the depositary’s office at all reasonable times, but solely for the purpose of communicating with other holders in the interest of the business of our company or a matter relating to the deposit agreement. Such register may be closed from time to time, when deemed expedient by the depositary.

The depositary will maintain facilities for the delivery and receipt of ADRs.

Pre-Release of ADSs

In its capacity as depositary, the depositary shall not lend common shares or ADSs; provided, however, that the depositary may (i) issue ADSs prior to the receipt of common shares and (ii) deliver common shares prior to the receipt of ADSs for withdrawal of deposited securities, including ADSs which were issued under (i) above but for which common shares may not have been received (each such transaction a “pre-release”). The depositary may receive ADSs in lieu of common shares under (i) above (which ADSs will promptly be canceled by the depositary upon receipt by the depositary) and receive common shares in lieu of ADSs under (ii) above. Each such pre-release will be subject to a written agreement whereby the person or entity (the “applicant”) to whom ADSs or common shares are to be delivered (1) represents that at the time of the pre-release the applicant or its customer owns the common shares or ADSs that are to be delivered by the applicant under such pre-release, (2) agrees to indicate the depositary as owner of such common shares or ADSs in its records and to hold such common shares or ADSs in trust for the depositary until such common shares or ADSs are delivered to the depositary or the custodian, (3) unconditionally guarantees to deliver to the depositary or the custodian, as applicable, such common shares or ADSs, and (4) agrees to any additional restrictions or requirements that the

228

depositary deems appropriate. Each such pre-release will be at all times fully collateralized with cash, U.S. government securities or such other collateral as the depositary deems appropriate, terminable by the depositary on not more than five business days’ notice and subject to such further indemnities and credit regulations as the depositary deems appropriate. The depositary will normally limit the number of ADSs and common shares involved in such pre-release at any one time to 30% of the ADSs outstanding (without giving effect to ADSs outstanding under (i) above), provided, however, that the depositary reserves the right to change or disregard such limit from time to time as it deems appropriate. The depositary may also set limits with respect to the number of ADSs and common shares involved in pre-release with any one person on a case-by-case basis as it deems appropriate. The depositary may retain for its own account any compensation received by it in conjunction with the foregoing. Collateral provided in connection with pre-release transactions, but not the earnings thereon, shall be held for the benefit of the registered holders of ADRs (other than the applicant).

Appointment

In the deposit agreement, each registered holder of ADRs and each person holding an interest in ADSs, upon acceptance of any ADSs (or any interest therein) issued in accordance with the terms and conditions of the deposit agreement will be deemed for all purposes to:

• be a party to and bound by the terms of the deposit agreement and the applicable ADR or ADRs; and

• appoint the depositary as its attorney-in-fact, with full power to delegate, to act on its behalf and to take any and all actions contemplated in the deposit agreement and the applicable ADR or ADRs, to adopt any and all procedures necessary to comply with applicable laws and to take such action as the depositary in its sole discretion may deem necessary or appropriate to carry out the purposes of the deposit agreement and the applicable ADR and ADRs, the taking of such actions to be the conclusive determinant of the necessity and appropriateness thereof.

Governing Law

The deposit agreement and the ADRs will be governed by and construed in accordance with the laws of the State of New York. In the deposit agreement, we have submitted to the jurisdiction of the courts of the State of New York and appointed an agent for service of process on our behalf. By holding an ADS or an interest therein, registered holders of ADRs and beneficial owners of ADSs each irrevocably agree that any legal suit, action or proceeding against or involving us or the depositary, arising out of or based upon the deposit agreement or the transactions contemplated thereby, may only be instituted in a state or federal court in New York, New York, and each irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding.

229

TAXATION

Peruvian Tax Considerations

The following is a general summary of material Peruvian tax matters under Peruvian law, as in effect on the date of this prospectus and describes the principal tax consequences of ownership of ADSs by non-resident individuals or entities (“Non-Peruvian Holders”). Legislative, judicial or administrative changes or interpretations may, however, be forthcoming. Any such changes or interpretations could affect the tax consequences to holders of ADSs and could alter or modify the conclusions set forth herein. This summary is not intended to be a comprehensive description of all of the tax considerations that may be relevant to a decision to make an investment in the ADSs. In addition, it does not describe any tax consequences arising under the laws of any taxing jurisdiction other than Peru or applicable to an individual or entity resident of Peru or to a person with a permanent establishment in Peru. To the extent that the discussion relates to matters of Peruvian tax law, except as otherwise provided, it represents the opinion of Muñiz, Ramírez, Pérez-Taiman & Olaya Abogados.

For purposes of Peruvian taxation:

• individuals are residents of Peru, if they are Peruvian nationals who have established their place of residence in Peru or if they are foreign nationals with a permanence of 183 days in Peru in any 12-month period (in the latter case, the condition of Peruvian resident can only be acquired as of the 1st of January of the year following the fulfillment of residence conditions); and

• legal entities are residents of Peru if they are established or incorporated in Peru.

Cash Dividends and Other Distributions

Cash dividends paid to Non-Peruvian Holders with respect to common shares and amounts distributed with respect to ADSs are currently subject to Peruvian withholding income tax at a rate of 4.1%. As a general rule, the distribution of additional common shares representing profits, the distribution of shares which differ from the distribution of earnings or profits, as well as the distribution of preemptive rights with respect to common shares, which are carried out as part of a pro rata distribution to all shareholders, will not be subject to Peruvian income tax or withholding taxes.

Capital Gains

Pursuant to Article 6 of the Peruvian income tax law, individuals and entities resident in Peru are subject to Peruvian income tax on their worldwide income while Non-Peruvian Holders are subject to Peruvian income tax only on their Peruvian source income.

Peruvian income tax law provides that income derived from the disposal of securities issued by Peruvian entities is considered Peruvian source income and is therefore subject to income tax. Under current Peruvian income tax law, capital gains resulting from the disposal of ADRs that represent shares issued by Peruvian entities are considered Peruvian source income and therefore are subject to Peruvian income tax. Peruvian income tax law also provides that the taxable income resulting from the disposal of securities is equal to the difference between the sale price of the securities (which may not be less than their fair market value) and their tax basis.

Notwithstanding the foregoing, capital gains resulting from the disposal of ADSs or beneficial interest in ADSs that represent shares issued by a Peruvian entity are not considered Peruvian source income, and therefore are not subject to Peruvian income tax.

In the event ADSs are exchanged into common shares and such common shares are disposed of, capital gains resulting therefrom will be subject to an income tax rate of either 5% or 30%, depending on where the transaction takes place. If the transaction is consummated in Peru, any capital gain will be subject to an income

230

tax rate of 5%; and if the transaction is consummated outside of Peru, any capital gain will be subject to a 30% income tax rate. Peruvian income tax law regulations have stated with respect to the transfer of common shares that transactions are deemed to be consummated in Peru if the common shares are transferred through the Lima Stock Exchange. Any gain resulting from the conversion of ADSs into common shares or common shares into ADSs will not be subject to taxation in Peru.

Any Non-Peruvian Holder who acquires common shares will have the following tax basis: (i) for common shares purchased by the transferor, the acquisition price paid for the shares; (ii) for common shares received by the transferor as a result of a share capital increase because of a capitalization of net profits, the par value of such common shares; (iii) for other common shares received free of any payment, tax basis will be: (x) zero or the cost borne by the transferor, in the case of individuals and (y) the fair market value at the time of the acquisition, in the case of entities, and (iv) for common shares of the same type acquired at different opportunities and at different values, the tax basis will be the weighted average cost. In cases where common shares are sold by Non-Peruvian Holders outside the Lima Stock Exchange, the tax basis must be certified by the Peruvian tax administration prior to the time payment is made to the transferor; otherwise it would not be possible to deduct the tax basis and the 30% Peruvian income tax would apply to the total sale price. Under Peruvian income tax law, tax basis certification is granted by the Peruvian tax authorities within 30 business days after the filing of the corresponding application. If the Peruvian tax authorities do not respond within such 30 day period, the tax basis calculation presented for approval by the transferor is deemed automatically approved.

In any transaction relating to Peruvian securities through the Lima Stock Exchange, CAVALI (the Peruvian clearing house) will act as withholding agent of the Peruvian income tax. If the purchaser is resident in Peru and the sale is not performed through the Lima Stock Exchange, the purchaser will act as withholding agent. In other cases, the transferor shall be obliged to self-assess the tax and pay it to the Peruvian tax authorities within the first 12 business days of the month following the transfer.

Other Considerations

No Peruvian estate or gift taxes are imposed on the gratuitous transfer of ADSs or common shares. No stamp, transfer or similar tax applies to any transfer of common shares, except for commissions payable by seller and buyer to the Lima Stock Exchange (0.15% of value sold), fees payable to the Peruvian Securities Commission (0.1% of value sold), brokers’ fees (about 0.05% to 0.50% of value sold) and value added tax (at the rate of 18%) on commissions and fees. Any investor who sells its common shares on the Lima Stock Exchange will incur these fees and taxes upon purchase and sale of the common shares.

United States Federal Income Tax Considerations

The following summary describes certain United States federal income tax consequences to a United States Holder (as defined below) of the purchase, ownership and disposition of our common shares and ADSs as of the date hereof. Except where noted, this summary deals only with common shares and ADSs held as capital assets (generally, property held for investment). As used herein, the term “United States Holder” means a beneficial owner of common shares or ADSs that is for United States federal income tax purposes:

• an individual citizen or resident of the United States;

• a corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

• an estate the income of which is subject to United States federal income taxation regardless of its source; or

• a trust if it (1) is subject to the primary supervision of a court within the United States and one or more United States persons have the authority to control all substantial decisions of the trust, or (2) has a valid election in effect under applicable United States Treasury regulations to be treated as a United States person.

231

This summary does not represent a detailed description of the United States federal income tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws, including if you are:

• a dealer in securities or currencies;

• a financial institution;

• a regulated investment company;

• a real estate investment trust;

• an insurance company;

• a tax-exempt organization;

• a person holding our common shares or ADSs as part of a hedging, integrated or conversion transaction, a constructive sale or a straddle;

• a trader in securities that has elected the mark-to-market method of accounting for your securities;

• a person liable for alternative minimum tax;

• a person who owns or is deemed to own 10% or more of our voting stock;

• a partnership or other pass-through entity for United States federal income tax purposes; or

• a person whose “functional currency” is not the U.S. dollar.

The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and regulations, rulings and judicial decisions thereunder as of the date hereof, and such authorities may be replaced, revoked or modified so as to result in United States federal income tax consequences different from those discussed below. There is currently no income tax treaty between the United States and Peru that would provide for United States federal income tax consequences different than the consequences under the foregoing authorities. In addition, this summary is based, in part, upon representations made by the depositary to us and assumes that the deposit agreement, and all other related agreements, will be performed in accordance with their terms.

If a partnership (or other entity treated as a partnership for United States federal income tax purposes) holds our common shares or ADSs, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our common shares or ADSs, you should consult your tax advisors.

This summary does not contain a detailed description of all the United States federal income tax consequences to you in light of your particular circumstances and does not address the effects of any state, local or non-United States tax laws. If you are considering the purchase, ownership or disposition of our common shares or ADSs, you should consult your own tax advisors concerning the United States federal income tax consequences to you in light of your particular situation as well as any consequences arising under the laws of any other taxing jurisdiction.

ADSs

If you hold ADSs, for United States federal income tax purposes, you generally will be treated as the owner of the underlying common shares that are represented by such ADSs. Accordingly, deposits or withdrawals of common shares for ADSs will not be subject to United States federal income tax.

232

Taxation of Dividends

The gross amount of distributions, other than certain pro rata distributions of common shares, on the ADSs or common shares (including amounts withheld to reflect Peruvian withholding taxes) will be taxable as dividends, to the extent paid out of our current or accumulated earnings and profits, as determined under United States federal income tax principles.

To the extent that the amount of any distribution (including amounts withheld to reflect Peruvian withholding taxes) exceeds our current and accumulated earnings and profits for a taxable year, as determined under United States federal income tax principles, the distribution will first be treated as a tax-free return of capital, causing a reduction in the adjusted basis of the ADSs or common shares, and the balance in excess of adjusted basis will be taxed as capital gain recognized on a sale or exchange. However, we do not expect to keep earnings and profits in accordance with United States federal income tax principles. Therefore, you should expect that a distribution will generally be treated as a dividend. Such dividends (including any withheld taxes) will be includable in your gross income as ordinary income on the day actually or constructively received by you, in the case of the common shares, or by the depositary, in the case of ADSs. Such dividends will not be eligible for the dividends received deduction allowed to corporations under the Code.

With respect to non-corporate United States Holders, certain dividends received from a qualified foreign corporation may be subject to reduced rates of taxation. A non-United States corporation is treated as a qualified foreign corporation with respect to dividends received from that corporation on common shares (or ADSs backed by such shares) that are readily tradable on an established securities market in the United States. United States Treasury Department guidance indicates that upon the listing of our ADSs on the NYSE, our ADSs will be considered readily tradable on an established securities market in the United States. Based on existing guidance, it is not entirely clear whether our common shares will be considered readily tradable on an established securities market in the United States because only the ADSs, not the underlying common shares, will be listed on a securities market in the United States. We believe that dividends we pay on our common shares that are represented by ADSs, but not our common shares that are not so represented, will meet such conditions required for the reduced tax rates. There can be no assurance that our ADSs will be considered readily tradable on an established securities market in later years. Non-corporate United States Holders that do not meet a minimum holding period requirement during which they are not protected from the risk of loss or that elect to treat the dividend income as “investment income” pursuant to Section 163(d)(4) of the Code will not be eligible for the reduced rates of taxation regardless of our status as a qualified foreign corporation. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. You should consult your own tax advisors regarding the application of these rules given your particular circumstances.

The amount of any dividend paid in nuevos soles will equal the U.S. dollar value of the nuevos soles received, calculated by reference to the exchange rate in effect on the date the dividend is actually or constructively received by you, in the case of the common shares, or by the depositary, in the case of ADSs, regardless of whether the nuevos soles are converted into U.S. dollars at that time. If the nuevos soles received as a dividend are converted into U.S. dollars on the date they are received, you generally will not be required to recognize foreign currency gain or loss in respect of the dividend income. If the nuevos soles received as a dividend are not converted into U.S. dollars on the date of receipt, you will have a tax basis in the nuevos soles equal to their U.S. dollar value on the date of receipt. Any gain or loss realized on a subsequent conversion or other disposition of the nuevos soles will be treated as United States source ordinary income or loss.

Subject to certain conditions and limitations, Peruvian withholding taxes on dividends may be treated as foreign taxes eligible for credit against your United States federal income tax liability. For purposes of calculating the foreign tax credit, dividends paid on the ADSs or common shares will be treated as foreign source income and will generally constitute passive category income. However, in certain circumstances, if you have held the ADSs or common shares for less than a specified minimum period during which you are not protected

233

from risk of loss, or are obligated to make payments related to the dividends, you will not be allowed a foreign tax credit for any Peruvian withholding taxes imposed on dividends paid on the ADSs or common shares. If you do not elect to claim a United States foreign tax credit, you may instead claim a deduction for Peruvian income tax withheld, but only for a taxable year in which you elect to do so with respect to all foreign income taxes paid or accrued in such taxable year. The rules governing the foreign tax credit are complex. You are urged to consult your tax advisors regarding the availability of the foreign tax credit under your particular circumstances.

Taxation of Capital Gains

For United States federal income tax purposes, you will recognize taxable gain or loss on any sale or exchange of ADSs or common shares in an amount equal to the difference between the amount realized for the ADSs or common shares and your tax basis in the ADSs or common shares, in each case as determined in U.S. dollars. Such gain or loss will generally be capital gain or loss. Capital gains of non-corporate United States Holders derived with respect to capital assets held for more than one year are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

If a Peruvian income tax is withheld on the sale or other disposition of our ADSs or common shares, your amount realized will include the gross amount of the proceeds of that sale or other disposition before deduction of the Peruvian income tax. See “Peruvian Tax Considerations—Capital Gains” for a description of when a sale or other disposition of our ADSs or common shares may be subject to taxation by Peru. Any gain or loss recognized by you will generally be treated as United States source gain or loss for foreign tax credit purposes. Consequently, in the case of gain from the disposition of ADSs or common shares that is subject to Peruvian income tax, you may not be able to benefit from the foreign tax credit for that Peruvian income tax (i.e., because the gain from the disposition would be United States source), unless you can apply the credit (subject to applicable limitations) against United States federal income tax payable on other income from foreign sources. Alternatively, you may take a deduction for the Peruvian income tax if you do not take a credit for any foreign taxes paid or accrued during the taxable year. You are urged to consult your tax advisors regarding the tax consequences if Peruvian income tax is imposed on a disposition of ADSs or common shares, including the availability of the foreign tax credit under your particular circumstances.

Passive Foreign Investment Company

We do not believe that we are, for United States federal income tax purposes, a passive foreign investment company (a “PFIC”), and we expect to operate in such a manner so as not to become a PFIC. If, however, we are or become a PFIC, you could be subject to additional United States federal income taxes on gain recognized with respect to the ADSs or common shares and on certain distributions, plus an interest charge on certain taxes treated as having been deferred under the PFIC rules. Non-corporate United States Holders will not be eligible for reduced rates of taxation on any dividends received from us (as discussed above under “—Taxation of Dividends”) if we are a PFIC in the taxable year in which such dividends are paid or in the preceding taxable year.

Information Reporting and Backup Withholding

In general, information reporting will apply to dividends in respect of our ADSs or common shares and the proceeds from the sale, exchange or redemption of our ADSs or common shares that are paid to you within the United States (and in certain cases, outside the United States), unless you are an exempt recipient. Backup withholding may apply to such payments if you fail to provide a taxpayer identification number or certification of other exempt status or fail to report in full dividend and interest income.

Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your United States federal income tax liability provided the required information is furnished to the Internal Revenue Service in a timely manner.

234

The above description is not intended to constitute a complete analysis of all tax consequences relating to the acquisition, ownership or disposition of our ADSs or common shares. You should consult your own tax advisors concerning the overall tax consequences to you, including the consequences under laws other than United States federal income tax laws, of an investment in our ADSs or common shares.

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting agreement dated                     , 2013, we have agreed to sell to the underwriters named below, for whom Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC are acting as representatives, and the underwriters have agreed to purchase, at a public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus, the following respective numbers of ADSs:

Underwriter	Number of ADSs
Credit Suisse Securities (USA) LLC
J.P. Morgan Securities LLC
Morgan Stanley & Co. LLC
Banco BTG Pactual S.A.—Cayman Branch
Banco Internacional del Perú S.A.A.—Interbank
BBVA Banco Continental
BCP Capital Financial Services S.A.
Total		16,279,070

Banco BTG Pactual S.A.—Cayman Branch, acting on behalf of BTG Pactual US Capital LLC, is acting as an underwriter in this offering. Banco BTG Pactual S.A.—Cayman Branch is not a broker-dealer registered with the SEC and therefore may not make sales of any ADSs in the United States or to U.S. persons except in compliance with applicable U.S. laws and regulations. To the extent that Banco BTG Pactual S.A.—Cayman Branch intends to effect sales of ADSs in the United States, it will do so only through BTG Pactual US Capital LLC or one or more U.S. registered broker-dealers, or otherwise as permitted by applicable U.S. law.

Banco Internacional del Perú S.A.A.—Interbank, BBVA Banco Continental and BCP Capital Financial Services S.A. are not broker-dealers registered with the SEC and therefore may not make offers or sales of any of our ADSs in the United States or to U.S. persons. Each of Banco Internacional del Perú S.A.A.—Interbank, BBVA Banco Continental and BCP Capital Financial Services S.A. has agreed that it does not intend to and will not offer or sell any of our ADSs in the United States or to U.S. persons in connection with this offering.

The underwriting agreement provides that the underwriters are obligated to purchase all the ADSs in the offering if any are purchased, other than those ADSs covered by the over-allotment option to purchase additional ADSs described below. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering may be terminated.

All sales of the ADSs in the United States will be made by U.S. registered broker/dealers.

We have granted to the underwriters a 30-day option to purchase on a pro rata basis up to 2,441,860 additional ADSs from us at the initial public offering price less the underwriting discounts and commissions. The option may be exercised only to cover any over-allotments of ADSs.

The underwriters propose to offer the ADSs initially at the public offering price on the cover page of this prospectus and to selling group members at that price less a selling concession of US$             per ADS. The underwriters and selling group members may allow a discount of US$             per ADS on sales to other broker/dealers. After the initial public offering, the representatives may change the public offering price and concession and discount to broker/dealers.

236

The following table summarizes the compensation we will pay to the underwriters:

	Per ADS		Total
	Without Exercise of Over-allotment Option	With Exercise  of Over-allotment Option	Without Exercise of Over-allotment Option	With Exercise  of Over-allotment Option
Underwriting discounts and commissions	US$	US$	US$	US$

The representatives have informed us that the underwriters do not expect sales to accounts over which the underwriters have discretionary authority to exceed 5% of the ADSs being offered.

We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees, legal and accounting expenses, but excluding underwriting discounts and commissions, will be approximately US$4.4 million. See “Expenses of the Offering.”

We have agreed to reimburse the underwriters for their road show expenses, the legal fees and expenses of underwriters’ counsel (including legal fees and expenses for qualifying the offering with the Financial Industry Regulatory Authority) and other out-of-pocket expenses of the underwriters payable by us, in an aggregate amount not to exceed US$2.1 million.

We have agreed that we will not offer, sell, issue, contract to sell, pledge, or otherwise dispose of, directly or indirectly, or file with the SEC a registration statement under the Securities Act, relating to, any of our ADSs, common shares or securities convertible into or exchangeable or exercisable for, or that represent the right to receive, our ADSs or common shares, or enter into any swap, hedge or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of our ADSs or common shares, or publicly disclose that we will or may enter into any transaction described above, without the prior written consent of the representatives of the underwriters for a period of 180 days after the date of this prospectus, whether any transaction described above is to be settled by delivery of ADSs, common shares or such other securities, in cash or otherwise, except for issuances pursuant to the sale of ADSs or common shares to the underwriters, grants of employee stock options pursuant to the terms of a plan in effect on the date of this prospectus, issuances of securities pursuant to the exercise of such options or the exercise of any other employee stock options outstanding on the date of this prospectus. However, in the event that either (1) during the last 17 days of the “lock-up” period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the “lock-up” period, we announce that we will release earnings results during the 16-day period beginning on the last day of the “lock-up” period, then in either case the expiration of the “lock-up” will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of the material news or event, as applicable, unless the representatives of the underwriters waive, in writing, such an extension.

Our directors and officers and certain of our other shareholders, collectively owning 36.76% of our common shares as of April 30, 2013, have agreed, subject to limited exceptions, that they will not offer, sell, contract to sell, pledge or otherwise transfer or dispose of, directly or indirectly, any of our ADSs, common shares or securities convertible into or exchangeable or exercisable for, or that represent the right to receive, ADSs or common shares, enter into any transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of our ADSs or common shares, or publicly disclose the intention to enter into any transaction described above, without the prior written consent of the representatives of the underwriters for a period of 180 days after the date of this prospectus, whether any transaction described above is to be settled by delivery of ADSs, common shares or such other securities, in cash or otherwise. However, in the event that either (1) during the last 17 days of the “lock-up” period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the “lock-up” period, we announce that we will release earnings results during the

237

16-day period beginning on the last day of the “lock-up” period, then in either case the expiration of the “lock-up” will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of the material news or event, as applicable, unless the representatives of the underwriters waive, in writing, such an extension.

The representatives, in their sole discretion, may release the ADSs and other securities subject to the lock-up agreements described above in whole or in part at any time with or without notice.

We have agreed to indemnify the underwriters against liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in that respect.

We have applied to have our ADSs approved for listing on the New York Stock Exchange under the symbol “GRAM”. Our common shares are listed on the Lima Stock Exchange under the symbol “GRAMONC1”.

In connection with the offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act.

• Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

• Over-allotment involves sales by the underwriters of ADSs in excess of the number of ADSs the underwriters are obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of ADSs over-allotted by the underwriters is not greater than the number of ADSs that they may purchase in the over-allotment option. In a naked short position, the number of ADSs involved is greater than the number of ADSs in the over-allotment option. The underwriters may close out any covered short position by either exercising their over-allotment option and/or purchasing ADSs in the open market.

• Syndicate covering transactions involve purchases of the ADSs in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of ADSs to close out the short position, the underwriters will consider, among other things, the price of ADSs available for purchase in the open market as compared to the price at which they may purchase ADSs through the over-allotment option. If the underwriters sell more ADSs than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying ADSs in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the ADSs in the open market after pricing that could adversely affect investors who purchase in the offering.

• Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the ADSs originally sold by the syndicate member is purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our ADSs or preventing or retarding a decline in the market price of the ADSs. As a result the price of our ADSs may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the NYSE or otherwise and, if commenced, may be discontinued at any time.

The underwriters and/or their affiliates may enter into derivative transactions with clients, at their request, in connection with the common shares or the ADSs. The underwriters and/or their affiliates may also purchase some of the ADSs to hedge their risk exposure in connection with such transactions. These transactions may have an effect on demand, price or other terms of the offering.

238

The underwriters and/or their respective affiliates have provided, currently provide or may provide in the future various investment banking, commercial banking, financial advisory and/or similar services to us on a regular basis, and maintain normal business relationships with us in their capacity as credit institutions or as lenders under credit facilities, for which they have received and may continue to receive customary fees and commissions. Affiliates of certain of the underwriters are lenders under the US$150 million syndicated term loan with BBVA Bancomer S.A., Institución de Banca Múltiple, Grupo Financiero BBVA Bancomer, as administrative agent, and the other lenders party thereto.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to our assets, securities and/or instruments (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with us.

A prospectus in electronic format may be made available on the web sites maintained by one or more of the underwriters, or selling group members, if any, participating in this offering and one or more of the underwriters participating in this offering may distribute prospectuses electronically. The representatives may agree to allocate a number of ADSs to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the underwriters and selling group members that will make internet distributions on the same basis as other allocations.

WHERE YOU CAN FIND MORE INFORMATION

We have filed with the SEC a registration statement (including amendments and exhibits to the registration statement) on Form F-1 under the U.S. Securities Act. This prospectus, which is part of the registration statement, does not contain all of the information set forth in the registration statement and the exhibits and schedules to the registration statement. For further information, we refer you to the registration statement and the exhibits and schedules filed as part of the registration statement. If a document has been filed as an exhibit to the registration statement, we refer you to the copy of the document that has been filed.

Upon completion of this offering, we will become subject to the informational requirements of the U.S. Securities Exchange Act of 1934, or the Exchange Act. Accordingly, we will be required to file reports and other information with the SEC, including annual reports on Form 20-F and reports on Form 6-K. You may inspect and copy reports and other information to be filed with the SEC at the public reference facilities maintained by the SEC at 100 F Street, N.E., Washington, D.C. Copies of the materials may be obtained from the Public Reference Room of the SEC at 100 F Street, N.E., Washington, D.C. 20549 at prescribed rates. The public may obtain information on the operation of the SEC’s Public Reference Room by calling the SEC in the United States at 1-800-SEC-0330. In addition, the SEC maintains an Internet website at http://www.sec.gov, from which you can electronically access the registration statement and its materials.

As a foreign private issuer, we are not subject to the same disclosure requirements as a domestic U.S. registrant under the Exchange Act. For example, we are not required to prepare and issue quarterly reports. However, we intend to furnish our shareholders with annual reports containing consolidated financial statements audited by our independent auditors and to make available to our shareholders quarterly reports containing unaudited financial data for the first three quarters of each fiscal year. In addition, as a foreign issuer, we are not subject to the proxy rules under Section 14 of the Exchange Act and our officers and directors will not be subject to Section 16 of the Exchange Act relating to insider short-swing profit disclosure and recovery regime.

We will send the depositary a copy of all notices that we give relating to meetings of our shareholders or to distributions to shareholders or the offering of rights and a copy of any other report or communication that we make generally available to our shareholders. The depositary will make all these notices, reports and communications that it receives from us available for inspection by registered holders of ADSs at its office. The depositary will mail copies of those notices, reports and communications to you if we ask the depositary to do so and furnish sufficient copies of materials for that purpose.

We will file financial statements and other periodic reports with the Peruvian Securities Commission in Peru. Issuers of securities registered with the Peruvian Securities Commission are required to disclose material information relating to the issuer. Pursuant to the Securities Market Law and relevant regulations enacted thereunder, all material information in connection with the issuer of registered securities, its activities or securities issued or secured by such issuer which may influence the liquidity or price of such securities must be disclosed. Accordingly, issuers must file with the Peruvian Securities Commission mainly two types of information: (a) financial information, including unaudited interim financial statements on a quarterly basis (which are not required to be subject to limited review), and audited annual consolidated financial statements on an annual basis, and (b) material information relating to the issuer and its activities that may significantly affect the price, offering or negotiation of the issued securities, and in general, all the information that may be relevant for investors to be able to make investment decisions.

ENFORCEMENT OF JUDGMENTS AGAINST FOREIGN PERSONS

Graña y Montero is a publicly-held corporation (sociedad anónima abierta) organized and existing under the laws of Peru. All of our directors and officers reside in Peru or elsewhere outside the United States, and a significant portion of the assets of such persons may be, and substantially all of our assets are, located in Peru or elsewhere outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon us or upon our directors or officers, or to enforce against them, or us, in U.S. federal or state courts judgments predicated upon the provisions of civil liabilities of U.S. federal securities laws.

We have been advised by our Peruvian counsel, Muñiz, Ramírez, Pérez-Taiman & Olaya Abogados, that there is uncertainty as to the enforceability, in original actions in Peruvian courts, of liabilities predicated upon the U.S. federal securities laws. In addition, we have been advised by Muñiz, Ramírez, Pérez-Taiman & Olaya Abogados that any final and conclusive judgment for a fixed and definitive sum obtained against us in any foreign court having jurisdiction in respect of any suit, action or proceeding against us for the enforcement of any of our obligations under the common shares that are governed by New York law will, upon request, be deemed valid and enforceable in Peru through an exequatur judiciary proceeding (which does not involve the reopening of the case), provided that: (i) there is in effect a treaty between the country where said foreign court sits and Peru regarding the recognition and enforcement of foreign judgments; or (ii) in the absence of such a treaty, the original judgment is ratified by the Peruvian Courts (Cortes de la República del Perú), provided that the following conditions and requirements are met:

• the judgment does not resolve matters under the exclusive jurisdiction of Peruvian courts (and the matters contemplated in respect of this prospectus or the common shares are not matters under the exclusive jurisdiction of Peruvian courts);

• such court had jurisdiction under its own conflicts of law rules and under general principles of international procedural jurisdiction;

• Graña y Montero received service of process in accordance with the laws of the place where the proceeding took place, was granted a reasonable opportunity to appear before such foreign court, and was guaranteed due process rights;

• the judgment has the status of res judicata as defined in the jurisdiction of the court rendering such judgment;

• no pending litigation in Peru between the same parties for the same dispute was initiated before the commencement of the proceeding that concluded with the foreign judgment;

• the foreign judgment is not incompatible with another judgment that fulfills the requirements of recognition and enforceability established by Peruvian Corporations law, unless such foreign judgment was rendered first;

• the foreign judgment is not contrary to Peruvian public policy or good morals;

• it is not proven that such foreign court denies enforcement of Peruvian judgments or engages in a review of the merits thereof; and

• such judgment has been (i) duly apostilled by the competent authority of the jurisdiction of the issuing court, in case of jurisdictions that are party to the Hague Apostille Convention, and is accompanied by a certified and officially translated copy of such judgment into Spanish; and (ii) the applicable court taxes or fees have been paid.

Our properties and subsidiaries have no immunity from a court’s jurisdiction, except, to the extent applicable, immunities set forth in Article 616 of the Peruvian Code of Civil Procedure (Código Procesal Civil) for attachments on assets dedicated to the rendering of public services.

248

We have no reason to believe that any of our obligations relating to the common shares would be contrary to Peruvian public policy, good morals and international treaties binding upon Peru or generally accepted principles of international law. No treaty exists between the United States and Peru for the reciprocal enforcement of foreign judgments. Peruvian courts, however, have enforced judgments rendered in the United States based on legal principles of reciprocity and comity.

Our by-laws include an arbitration clause applicable to disputes arising from the interpretation of our by-laws or Peruvian Corporate Law and their complementary provisions, among us, our management and our shareholders. We have been advised. The arbitration clause does not apply to claims based on violations of United States securities laws in connection with this offering, unless agreed to by the parties to a claim. Our Peruvian Counsel, Muñiz, Ramirez, Perez-Taiman & Olaya Abogados, has provided us with their opinion to that effect.

Report of Independent Registered Public Accounting Firm

July 2, 2013

To Graña y Montero S.A.A. shareholders and Board of Directors:

In our opinion, the accompanying consolidated statement of financial position and the related consolidated income statement, consolidated statements of comprehensive income, shareholder’s equity and cash flows present fairly, in all material respects, the financial position of Graña y Montero S.A.A. and its subsidiaries at December 31, 2012 and December 31, 2011, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2012 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 32 to the consolidated financial statements, the company has restated its statement of cash flows for the year ended December 31, 2012 to correct errors.

d) Authorization for issue of the financial statements -

The consolidated financial statements of Graña y Montero S.A.A. for the year ended December 31,

2012 have been prepared and authorized for issuance by its Chief Financial Officer on June 3, 2013 and will be submitted to the Board of Directors within the term established by law.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The principal accounting policies applied in the preparation of these consolidated financial statements are set out below. These policies have been consistently applied to all the years presented, unless otherwise stated.

2.1 Basis of preparation

The consolidated financial statements of Graña y Montero S.A.A. have been prepared in accordance with International Financial Reporting Standards (IFRS) and IFRIC interpretations as issued by the International Accounting Standards Board.

The consolidated financial statements have been prepared under the historical cost convention, except for derivative financial instruments and available-for-sale financial assets which are measured at fair value. The financial statements are presented in thousands of New Peruvian Soles, unless otherwise stated.

The preparation of the consolidated financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group’s accounting policies.The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in Note 4.

2.2 Consolidation of financial statements

a) Subsidiaries -

Subsidiaries are all entities over which the Company has the power to govern the financial and operating policies, generally accompanying a shareholding of more than one half of the voting rights.

Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases.

The Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities assumed and the equity instruments issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The Group recognizes any non-controlling interest in the acquiree on an acquisition-by-acquisition basis, either at fair value or at the non-controlling interest’s proportionate share of the recognized amounts of acquiree’s identifiable net assets.

Acquisition-related costs are expensed as incurred.

Goodwill is initially measured as the excess of the aggregate of the consideration transferred and the fair value of non-controlling interest over the net identifiable assets acquired and liabilities assumed. If this consideration is lower than the fair value of the net assets of the subsidiary acquired, the difference is recognized in profit or loss at the time of acquisition.

F-14

(All amounts are expressed in thousands of S/. unless otherwise stated)

Balances, income and expenses from transactions between Group companies are eliminated. Profits and losses resulting from inter-company transactions that are recognized as assets are also eliminated. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

b) Changes in ownership interests in subsidiaries without change of control -

Transactions with non-controlling interests that do not result in loss of control are accounted for as equity transactions - that is, as transactions with the owners in their capacity as owners. The difference between fair value of any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests, which do not result in changes in the control of the subsidiary, are also recorded in equity at the time of disposal.

c) Disposal of subsidiaries -

When the Group ceases to have control over a subsidiary any retained interest in the entity is re-measured to its fair value at the date when control is lost, with the change in carrying amount recognized in profit or loss at such date. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

d) Joint Operations -

Jointly controlled operations involve the use of assets and other resources of the venturers rather than the establishment of a separate entity. Each venturer uses its own assets, incurs its own expenses and liabilities, and raises its own finance. Because the assets, liabilities, income and expenses are recognized in the financial statements of the venturer, no adjustments or other consolidation procedures are required in respect of these items when the venturer presents consolidated financial statements.

e) Associates -

Associates are all entities over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting. Under the equity method, the investment is initially recognized at cost, and the carrying amount is increased or decreased to recognize the Group’s share of the profit or loss of the investee after the date of acquisition. The Group’s investment in associates includes goodwill identified on acquisition, if the associate was acquired and not established with capital contributions.

If ownership interest in an associate of the Group is reduced but significant influence is retained, only a proportionate share of the amounts previously recognized in other comprehensive income is reclassified to profit or loss where appropriate.

The Group’s share of post-acquisition profit or loss is recognized in the income statement, and its share of post acquisition movements in other comprehensive income is recognized in other comprehensive income with a corresponding adjustment to the cost of the investment. When the Group’s share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Group does not recognize further losses, unless it has incurred legal or constructive obligations or made payments on behalf of the associate.

F-15

(All amounts are expressed in thousands of S/. unless otherwise stated)

The Group determines at each reporting date whether there is any objective evidence that the investment in the associate is impaired. If this is the case, the Group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognizes the amount adjacent to ‘share of profit of an associate’ in the income statement.

Profits and losses resulting from upstream and downstream transactions between the Group and its associates are recognized in the Group’s financial statements only to the extent of unrelated investor’s interests in the associates. Unrealized losses are eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.

2.3 Segment reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker of the Group. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Corporate General Manager.

If an entity changes the structure of its internal organization in a manner that causes the composition of its reportable segments to change, the Group restates the information for earlier periods unless the information is not available. Operating segments are identified based on the internal information effective at the date of the financial statements.

2.4 Foreign currency translation

a) Functional and presentation currency -

Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which each entity operates (the functional currency). The consolidated financial statements are presented in New Peruvian Soles, which is the Company’s functional currency and the Group’s presentation currency. All subsidiaries and Joint Operations use the New Peruvian Sol as their functional currency, except for subsidiaries abroad, for which the functional currency is the currency of the country in which they operate.

b) Transactions and balances -

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the date of the transactions or valuation when items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the changes at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except when deferred in equity as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings, cash and cash equivalents and other monetary items are presented in the income statement within exchange difference, net.

c) Group companies -

The results, assets and liabilities of Group entities (none of which has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency are changed into the presentation currency as follows:

i) assets and liabilities for each statement of the financial position presented are changed using the closing rate at the date of the statement of financial position;

F-16

(All amounts are expressed in thousands of S/. unless otherwise stated)

ii) income and expenses for each income statement are changed at the average exchange rate (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are changed using the rate on the date of the transaction);

iii) Capital is changed by using the historical exchange rate for each capital contribution made; and

iv) all resulting exchange differences are recognized as separate components in other comprehensive income. As of December 31, 2012 and 2011 the translation of foreign investments, with a currency other than the nuevo sol (Global change), did not generate relevant conversion differences.

Goodwill and fair value adjustments arising on the acquisition of a foreign entity are treated as assets and liabilities of the foreign entity and changed at the closing rate. Exchange differences arising are recognized in other comprehensive income.

2.5 Public services concessions

Concession agreements signed between the Group and the Peruvian Government are where the Group, as a concessionaire, assumes obligations for the construction or improvement of infrastructure and which qualify as public service concessions as defined by IFRIC 12, “Service Concession Arrangements”. The consideration to be received from the Government for the services of constructing or improving public infrastructure is recognized as a financial asset or as an intangible asset, as set forth below.

The following criteria are applied to the accounting of public service concession arrangements in accordance with IFRIC 12.

The government controls and regulates the infrastructure services provided by the Group and dictates to whom it must provide them and at what price. The concession agreement establishes the obligation for the Group to return the property to the grantor at the end of the concession period or when there is an expiration event. This feature gives the grantor control of the risks and rewards of the residual value of the assets at the end of the concession period. For this reason, the Group will not recognize the infrastructure as part of property, plant and equipment. However, the Group has the right of access and management rather than a right of use.

The Group manages two types of recognition for these concessions, it:

a) recognizes a financial asset to the extent that it has a contractual right to receive cash or another financial assets either because the Government secures the payment of specified or determinable amounts or because the Government will cover any difference arising from the amounts actually received from public service users in relation with the specified or determinable amounts. These financial assets are recognized initially at fair value and subsequently at amortized cost.

b) recognizes an intangible asset to the extent that the service agreement grants the Group a contractual right to charge users of the public service. The resulting intangible asset is measured at cost and it is amortized as described in Note 2.15.

a) The following are the concessions recognized by the Group as a financial asset:

i) Survial S.A. concession

Under the Survial concession, the Company operates and maintains a 750 km road from the San Juan de Marcona port to Urcos, Peru, which is connected to an interoceanic road that runs up to the Peruvian-Brazilian border. The road has five toll stations and three weigh stations. The concession was awarded to Survial in 2007 for a 25-year term. The Company owns 99.9% of Survial.

F-17

(All amounts are expressed in thousands of S/. unless otherwise stated)

The obligations under the concession include the construction of the road, which was completed in 2010. The revenue from this concession consists of an annual fee paid to Survial by the Peruvian Ministry of Transport and Communications in consideration for the operation and maintenance of the road, which fee can vary depending on the amount of maintenance required due to road damages. The revenue in this concession does not depend on traffic volume.

This concession is recognized as a financial asset because Survial has the unconditional contractual right to receive cash or other financial asset; such operation is secured contractually by the Peruvian Government. Survial receives specific and determinable amounts of cash and measures the financial asset at amortized cost, taking into consideration the effective interest rate set forth in IAS 39, ‘Financial Instruments: Recognition and Measurement’.

ii) Canchaque S.A.C. concession

Under the Canchaque concession, the Company operates and maintains a 78 km road from the towns of Buenos Aires to Canchaque, in Peru. The road has one toll station. The concession was awarded to Canchaque in 2006 for a 15-year term. The Company owns 99.9% of Canchaque. The obligations under the concession include the construction of the road, which was completed in 2009. Revenue from this concession consists of an annual fee paid by the Peruvian Ministry of Transport and Communications in consideration for the operation and maintenance of the road, which fee can vary depending on the amount of road maintenance required due to road wear and tear. The revenue received by the Company in this concession does not depend on traffic volume.

This concession granted to the Company comprises public services and investments qualifying as a financial asset as the Company has the unconditional right to receive cash or other financial assets from the collection of annual payments for maintenance and operation. Canchaque recognizes such financial asset at amortized cost, using in its calculation the interest rate set forth under IAS 39 Financial instruments: recognition and measurement.

iii) La Chira S.A. concession

In 2011, the Company was awarded a 25-year concession for the construction, operation and maintenance of La Chira waste water treatment plant in the south of Lima. The project is aimed at addressing Lima’s environmental problems caused by sewage discharged directly into the sea. The Company holds a 50% share in this project and the Company’s partner Acciona Agua holds the remaining 50%. La Chira’s annual revenues under the concession are in the form of a fee paid by Sedapal S.A., the public utility company responsible for the supervision of the water service in Lima.

This concession granted to the Company comprises public services and investments qualifying as a financial asset as the Company has the unconditional right to receive cash or other financial assets through collections of revenue charged for maintaining the plant.

The concession is recognized as a financial asset at its amortized cost, taking into consideration the effective interest rate calculation set forth in IAS 39, ‘Financial Instruments: Recognition and Measurement’.

iv) GyM Ferrovías S.A. concession

In 2011, the Company was awarded a 30-year concession for the operation of Line One of the Lima Metro, Peru’s only urban railway system. The concession was awarded to the subsidiary GyM Ferrovías, in which the Company holds a 75% ownership interest, with the other 25% being held by Ferrovías S.A.C. The obligations under the contract include (i) the operation and maintenance of the

F-18

(All amounts are expressed in thousands of S/. unless otherwise stated)

five existing trains provided by the government; (ii) the acquisition of 19 new trains on behalf of the Peruvian government, which will be the legal owner of such trains; (iii) the operation and maintenance of the 19 additional trains; and (iv) the design and construction of the railway maintenance and repair yard. Revenue from this concession consists of a quarterly fee that received from the Ministry of Transport and Communications based on the kilometers travelled per train. The revenue does not depend on passenger traffic volume.

The concession given to the Company comprises public services and investments qualifying as a financial asset as the Company has the unconditional right to receive cash or other financial asset for the collection of the secured kilometers.

The concession is recognized as a financial asset at its amortized cost, taking into consideration the effective interest rate calculation set forth in IAS 39, ‘Financial Instruments: Recognition and Measurement’.

b) The following are the concession is recognized by the Group as an intangible asset:

i) Norvial S.A. concession

Under the Norvial concession, the Company operates and maintains part of the only highway that connects Lima to the northwest of Peru. This 183-km road known as Red Vial 5, runs from the cities of Ancón to Pativilca and has three toll stations. The concession was awarded to Norvial in 2003 for a 25-year term. The Company owns 50.1% of Norvial. Norvial’s revenue derives from the collection of tolls. The toll fee is determined by the Peruvian Ministry of Transport and Communications and adjusted on a yearly basis in accordance with a contractual formula that takes into account the nuevo sol/U.S. dollar exchange rate and Peruvian and U.S. inflation. The Company is required to transfer 5.5% of monthly toll revenue to the Peruvian Ministry of Transport and Communications and pay a 1% regulatory fee to the Peruvian Supervisory Agency for Investment in Public Transportation Infrastructure. The obligations under the concession include expanding the already existing road by, among other things, adding two additional lanes. The first stage of construction was completed in 2008 and the second stage is expected to begin between 2014 and 2015. When the construction of the second stage begins, the Company will also be required to pay a one-time estimated fee of approximately US$1.8 million to the Peruvian Supervisory Agency for Investment in Public Transportation Infrastructure.

The concession given to the Company comprises public services and investments qualifying as an intangible asset because the concession agreement grants the right to charge a predefined and adjustable rate to users. The cost of the intangible comprises the investment committed, executed or to be executed to the extent their amount and borrowing costs can be estimated reliably.

See revenue recognition policy in Note 2.25-vii.

2.6 Cash and cash equivalents

In the consolidated statement of cash flows, cash and cash equivalents include cash on hand, on-demand bank deposits, other highly liquid investments with original maturities of three months or less and bank overdrafts. In the consolidated financial statements, bank overdrafts are included in the balance of financial obligations as current liabilities.

F-19

(All amounts are expressed in thousands of S/. unless otherwise stated)

2.7 Financial assets

2.7.1 Classification

The Group classifies its financial assets in the following categories: financial assets at fair value through profit or loss, financial assets held-to-maturity, loans and account receivables and financial assets available for sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at initial recognition. As of the date of the financial statements, the Group has classified its financial assets in the following two categories:

a) Loans and accounts receivable -

Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for maturities greater than 12 months after the statement of financial position. These are classified as non-current assets. The Group’s loans and receivables comprise ‘trade and other receivables’ and ‘cash and cash equivalents’.

b) Available-for-sale financial assets -

Available-for-sale financial assets are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless Management intends to dispose of it within 12 months of the date of the statement of financial position.

Available-for-sale financial assets are measured at fair value and changes in their value are recognized in other comprehensive income.

2.7.2 Recognition and measurement

Regular purchases and sales of financial assets are recognized on the trade-date, the date on which the Group commits to purchase or sell the asset. Investments are initially recognized at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Investments are derecognized when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets are subsequently carried at fair value. Loans and receivables are subsequently carried at amortized cost using the effective interest method.

If the fair value of available-for-sale assets cannot be estimated initially, they are maintained at cost.

Changes in the fair value of financial assets classified as available for sale are recognized in other comprehensive income.

When a financial asset classified as available for sale is sold or impaired, the accumulated fair value adjustments recognized in equity are included in the income statement.

Interest on available-for-sale securities, calculated using the effective interest method are recognized in the statement of comprehensive income as part of “other income”. Dividends on available-for-sale equity instruments are recognized in the statement of comprehensive income as part of “other income” when the Group’s right to receive payments is established.

2.8 Offsetting financial instruments

Financial assets and liabilities are offset and its net amount is reported in the statement of financial position when there is a legally enforceable right to offset the recognized amounts and there is an intention to settle on a net basis or realize the asset and settle the liability simultaneously.

F-20

(All amounts are expressed in thousands of S/. unless otherwise stated)

2.9 Impairment of financial assets

a) Assets carried at amortized cost -

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired. If a financial asset or a group of financial assets is impaired, the impairment losses are incurred only if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset (a ‘loss event’) and that loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets that can be reliably estimated.

Evidence of impairment may include, for example, indications that a debtor or a group of debtors is experiencing significant financial difficulty, default or delinquency in interest or principal payments, the probability that they will enter bankruptcy or other financial reorganization, and where observable data indicate that there is a measurable decrease in the estimated future cash flows.

For the loans and receivables category, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate. The carrying amount of the asset is reduced and the amount of the loss is recognized in the statement of comprehensive income. If a loan or an account receivable has a variable interest rate, the discount rate for measuring any impairment loss is the current effective interest rate determined under the contract. As a practical expedient, the Group may measure impairment on the basis of an instrument’s fair value using an observable market price, as long as it is verifiable.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the reversal of the previously recognized impairment loss is recognized in the income statement.

b) Assets classified as available for sale -

The Group assesses at the end of each reporting period whether there is objective evidence that a financial asset or a group of financial assets is impaired. For debt securities, the Group uses the criteria referred to in (a) above. In the case of equity investments, a significant or prolonged decline in the fair value of the security below its cost is also evidence that the assets are impaired. If any such evidence exists for available-for-sale financial assets, the cumulative loss - measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognized in profit or loss - is removed from equity and recognized in profit or loss. Impairment losses recognized in the income statement on equity instruments are not reversed through the income statement. If, in a subsequent period, the fair value of a debt instrument classified as available for sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognized in profit or loss, the impairment loss is reversed through the profit or loss of the period.

2.10 Derivative financial instruments and hedging activities

Derivatives are initially recognized at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. The method of recognizing the resulting gain or loss depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The Group designates certain derivatives as hedges of a particular risk associated with a recognized asset or liability or a highly probable forecast transaction (cash flow hedge).

The Group documents, at the inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging

F-21

(All amounts are expressed in thousands of S/. unless otherwise stated)

transactions. The Group also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items.

The fair values of various derivative instruments used for hedging purposes and changes in the account reserves for hedging in equity are disclosed in Note 3.3. The full fair value of a hedging derivative is classified as a non-current asset or liability when the remaining hedged item is more than 12 months and as a current asset or liability when the remaining maturity of the hedged item is less than 12 months. Trading derivatives are classified as a current asset or liability.

Cash flow hedge -

The effective portion of changes in the fair value of derivatives that are designated and qualify as fair value hedges is recognized as other comprehensive income. The gain or loss relating to the ineffective portion is recognized immediately in the statement of comprehensive income within ‘other comprehensive income’.

Amounts accumulated in equity are reclassified to profit or loss in the periods when the hedged item affects profit or loss (for example, when the forecast sale that is hedged takes place). The gain or loss relating to the effective portion of interest rate swaps hedging variable rate borrowings is recognized in the income statement. However, when the forecast transaction that is hedged results in the recognition of a non-financial asset (for example, inventory or fixed assets), the gains and losses previously deferred in equity are transferred from equity and are included in the initial measurement of the cost of the non-financial asset. The deferred amounts are ultimately recognized in cost of goods sold in the case of inventory or in depreciation in the case of fixed assets.

When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognized when the forecast transaction is ultimately recognized in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the statement of comprehensive income within ‘other (losses) gains- net’.

2.11 Trade accounts receivable

Trade accounts receivable are amounts due from customers for goods sold or services performed by the Company’s subsidiaries. If collection is expected in one year or less, they are classified as current assets. If not, they are presented as non-current assets.

Trade accounts receivable are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method, less provision for impairment.

2.12 Inventories

Inventory mainly includes land, work in progress and finished property which is assigned to the real- estate activity carried out by the Group. It also includes material used in the construction activity. Goods and supplies correspond to goods that the Group trades as part of its IT segment. Materials and supplies used in construction activities and IT equipment are determined under the weighted average cost method.

Land intended to carry out real estate projects is recognized at acquisition cost. Work in progress and finished property comprise design costs, material, labor costs, other indirect costs and general expenses related to the construction and do not include exchange differences.

Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. For the reductions in the carrying amount of inventories to their net realizable value, a provision is made for inventory impairment with a charge to the results of the period in which such reductions are made.

F-22

(All amounts are expressed in thousands of S/. unless otherwise stated)

IT equipment is stated at the lower of cost or net realizable value. Such cost does not exceed its net realizable value.

2.13 Investment properties

Investment properties are shown at cost less accumulated depreciation and impairment losses, if any. Subsequent costs attributable to investment properties are capitalized only if it is probable that future economic benefits will flow to the Company and the cost of these assets can be measured reliably; if not, they are recognized as expenses when incurred.

Repair and maintenance expenses are recognized in profit and loss when they are incurred. A property’s carrying amount is written down immediately to its recoverable amount if the property’s carrying amount is greater than its estimated recoverable amount. The cost and accumulated depreciation on disposals are eliminated from the respective accounts and the resulting gain or loss is recognized in profit or loss for the period. The depreciation of this asset is calculated under the straight-line method at a rate that is considered sufficient to absorb the property’s cost over its estimated useful life. The estimated useful life of this property is approximately 25 years.

The investment property maintained by the Group corresponds to a land owned by the subsidiary Viva GyM S.A. This investment is leased out under operating leases with third parties (see Note 2.32).

2.14 Property, plant and equipment

Property, plant and equipment are stated at historical cost less depreciation. Historical cost includes expenditure that is directly attributable to the acquisition of these items.

Subsequent costs are included in the asset’s carrying amount or are recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. The carrying amount of the replaced asset is derecognized. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.

Assets in the construction stage are capitalized as a separate component. At their completion, the cost of such assets is transferred to their definitive category.

Replacement units comprises long-term repairs which started to be depreciated at the date they replace for the related part.

Land is not depreciated. Depreciation of machinery and equipment and vehicles recognized as “Major equipment” are depreciated based on their hours of use. Under this method, the total number of work hours that machinery and equipment is capable to produce is estimated and a charge per hour is determined. The depreciation of other assets that do not qualify as “Major equipment” is calculated under the straight-line method to allocate their cost less their residual values over their estimated useful lives, as follows:

	Years
Buildings		33
Machinery and equipment		From 4 to 10
Vehicles		From 4 to 10
Furniture and fixtures		From 2 to 10
Other equipment		From 2 to 10
Replacement units		5

The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at each date of the statement of financial position. An asset’s carrying amount is written down immediately to its recoverable

F-23

(All amounts are expressed in thousands of S/. unless otherwise stated)

amount if the asset’s carrying amount is greater than its estimated recoverable amount. Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognized in “Other (losses) gains, net” in the income statement.

2.15 Intangible assets

a) Goodwill -

Goodwill arises on the acquisition of subsidiaries and represents the excess of the cost of acquisition as compared to the fair value of the Group’s share in the net identifiable assets at the acquisition date.

Goodwill acquired in a business combination is allocated to each of the cash-generating units (CGU), or group of CGUs, that is expected to benefit from the synergies of the combination. Each unit or group of units to which the goodwill is allocated represents the lowest level within the entity at which the goodwill is monitored for internal management purposes. Goodwill is monitored at the operating segment level.

Goodwill impairment reviews are undertaken annually or more frequently if events or changes in circumstances indicate a potential impairment. The carrying value of goodwill is compared to the recoverable amount, which is the higher of value in use and the fair value less costs to sell. Any impairment is recognized immediately as an expense and is not subsequently reversed.

b) Trademarks -

Separately acquired trademarks are shown at historical cost. Trademarks acquired in a business combination are recognized at fair value at the acquisition date. Trademarks have a finite useful life and are carried at cost less accumulated amortization. Amortisation is calculated using the straight-line method to allocate the cost of trademarks to profit or loss over their estimated useful lives, which has been estimated to be 30 years.

c) Concessions -

The intangible asset related to the right to charge users for the services under the Norvial concession is amortized under the straight-line method, from the date when toll collection started or from the date it is recognized as an asset using the lower of its estimated expected useful life or effective period of the concession agreement. See Note 2.5 regarding details of the Norvial concession.

d) Contractual relationships with customers -

Contractual relationships with customers are assets resulting from businesses that were initially recognized at fair value, as determined based on the future cash flows expected from those relationships over a period of time based on an estimation of the time period those customers remain customers for the Group. These assets are assessed periodically in order to determine whether they have been impaired, either from termination or deterioration of the relationship.

e) Block I and Block V -

The Company operates and extracts oil from two fields (Block I and Block V) located in the province of Talara in northern Peru. Both fields are operated under long-term service contracts in which the Company provides hydrocarbon extraction services to Perupetro, the state oil company. Hydrocarbons extracted from each field belong to Perupetro, which in turn pays the Company a variable fee per barrel of lifted hydrocarbons, which fee is based on a basket of international crude prices and the level of production. The fee is paid on a monthly basis. The Company’s activities are focused on proved reserves development and

F-24

(All amounts are expressed in thousands of S/. unless otherwise stated)

production and are conducted in mature oil fields, which have been producing oil for over 100 years in the case of Block I and over 50 years in the case of Block V. Such service contracts do not qualify as public services concessions, as defined by IFRIC 12. The extraction services that the Company provides and the infrastructure that it maintains are not a service that is provided to the public. Such infrastructure is not designed for public use and the services provided are exclusively for Perupetro.

As part of the company’s obligations under the service contracts, it is required to incur certain costs to prepare the wells to extract the hydrocarbons. The Company has capitalized as an intangible asset the development stage costs associated with preparing the wells for extraction. These costs are being amortized based on the useful life of the wells, which is less than the overall period of the service contract with Perupetro.

f) Internally generated software and development costs -

Costs associated with maintaining computer software programs are recognized as an expense as incurred. Development costs that are directly attributable to the design and testing of identifiable and unique software products controlled by the Group are recognized as intangible assets when the following criteria are met:

• it is technically feasible to complete the software product so that it will be available for use;

• management intends to complete the software product and use or sell it;

• there is an ability to use or sell the software product;

• it can be demonstrated how the software product will generate probable future economic benefits;

• adequate technical, financial and other resources to complete the development and to use or sell the software product are available; and

• the expenditure attributable to the software product during its development can be reliably measured.

Directly attributable costs that are capitalised as part of the software product include the software development employee costs and an appropriate portion of relevant overheads.

Other development expenditures that do not meet these criteria are recognised as an expense as incurred. Development costs previously recognised as an expense are not recognised as an asset in a subsequent period. Computer software development costs recognised as assets are amortised over their estimated useful lives, which does not exceed three years.

g) Land use rights -

This item comprises the rights of use of a physical space for the construction of future projects. The useful life of land use rights is 60 years under the agreement signed and their effective period can be extended if agreed by the parties. Amortization begins when it becomes ready for its intended use by Management.

2.16 Impairment of non-financial assets

Assets that have an indefinite useful life are not subject to amortization and are tested annually for impairment. Assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets other than goodwill that suffered impairment are reviewed for possible reversal of the impairment at each reporting date.

F-25

(All amounts are expressed in thousands of S/. unless otherwise stated)

2.17 Trade payables

Trade payables are obligations to pay for goods or services that have been acquired in the ordinary course of business. Accounts payable are classified as current liabilities if payment is due within one year or less (or in the normal operating cycle of the business if longer). If not, they are presented as non-current liabilities.

Trade payables are recognized initially at fair value and subsequently measured at amortized cost using the effective interest method.

2.18 Borrowings

Borrowings are recognized initially at fair value, net of transaction costs incurred. Borrowings are subsequently carried at amortized cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognized in the income statement over the period of the borrowings using the effective interest method.

Fees paid for entering into loan facilities are recognized as transaction costs of the loan to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw-down occurs.

2.19 Borrowing costs

General and specific borrowing costs directly attributable to acquisitions, construction or development of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets, until such time as the assets are substantially ready for their intended use or sale.

Investment income earned on the temporary investment of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs eligible for capitalization. All other borrowing costs are recognized in profit or loss in the period in which they are incurred.

2.20 Current and deferred income tax

The tax expense for the period comprises current and deferred tax. Tax is recognized in the income statement, except to the extent that it relates to items recognized in other comprehensive income or directly in equity. In this case, the tax is also recognized in statement of comprehensive income or directly in equity, respectively.

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the date of the statement of financial position in the countries where the Company and its subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. Management, where appropriate, establishes provisions on the basis of amounts expected to be paid to the tax authorities.

Deferred income tax is recognized, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. However, deferred tax liabilities are not recognized if they arise from the initial recognition of goodwill; deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantially enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilized.

F-26

(All amounts are expressed in thousands of S/. unless otherwise stated)

Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associates, except for deferred income tax liability where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority.

The deferred income tax arising from the temporary differences in subsidiaries, associates and interest in joint-controlled businesses is not recognized following the exception of IAS 12 in this regard, since the period for reversal of temporary differences is controlled by the Group and it is probable that these temporary differences will not be reversed in the near future.

2.21 Employee Benefits

a) Profit sharing -

The Group recognizes a liability and an expense for statutory workers’ profit sharing, based on the Peruvian legal regulations in force. Workers’ profit sharing is equivalent to 5% of the taxable income determined by each of the Group’s entities, according to the income tax law currently in force. Regarding the branch based in the Dominican Republic, the profit sharing rate is 10%.

b) Bonuses -

The Group recognizes an expense and the related liability for statutory bonuses based on applicable laws and regulations effective in Peru. Statutory bonuses comprise an additional one-month salary paid every year in July and December, respectively.

c) Severance indemnities -

The employees severance payments for time of service of the Group’s staff comprise their indemnification rights, calculated in accordance with the regulations in force, which have to be credited to the bank accounts designated by workers in May and November each year. The compensation for time of service amounts to an additional one-month’s salary effective at the date of bank deposits. The Group has no obligations to make any additional payments once the annual deposits to which workers are entitled to have been made.

d) Vacation leave -

Annual vacation leave is recognized on an accrual and cumulative basis. Provision for the estimated obligations of annual vacations is recognized at the date of the statement of financial position.

e) Pension plans -

The subsidiary CAM has commitments of pension plans with its workers. These commitments comprise both defined benefit and defined contribution plans. A defined benefit plan defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors such as age, years of service and compensation.

The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates as per IAS 19 that are denominated in the currency in which the

F-27

(All amounts are expressed in thousands of S/. unless otherwise stated)

benefits will be paid, and that have terms to maturity approximating to the terms of the related pension obligation. The discount rate reflects the time value of money but not the actuarial or investment risk. Additionally, the discount rate does not reflect the risk that the future events or circumstances may differ from actuarial assumptions.

Actuarial gains and losses arising from experience adjustments of pension benefits, are stated directly in other comprehensive income items.

Past-service costs are recognised immediately in income, unless the changes to the pension plan are conditional on the employees remaining in service for a specified period of time. In this case, the past-service costs are amortised on a straight-line basis over this period.

2.22 Provisions

a) General -

Provisions are recognized when the Group has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount has been reliably estimated. If the time value of money is significant, provisions are discounted using a pre-tax rate that reflects, when applicable, the specific risks related to the liability. Reversal of the discount due to the passage of time results in the obligation being recognized with a charge to the income statement as a financial expense. Restructuring provisions comprise lease termination penalties and employee termination payments. Provisions are not recognized for future operating losses.

Contingent obligations are disclosed only when their existence will be confirmed with future events or when their amount cannot be reliably estimated. Contingent assets are not recognized and only revealed if it is probable that future economic benefits will flow to the Company.

b) Provision for the closure of production wells -

Group entities recognize a provision for the closure of operating units that correspond to the legal obligation to close oil production wells once the production phase has been completed. At the initial date of recognition, the liability that arises from said obligation is measured at fair value discounted to present value, the same amount is simultaneously charged to the intangible account in the statement of financial position.

Subsequently, the liability will increase in each period to reflect the financial cost considered in the initial measurement of the discount, and the capitalized cost is depreciated based on the useful life of the related asset. When a liability is settled, the Group’s entities will recognize any gain or loss that may arise. The fair value changes estimated for the initial obligation and interest rates are recognized as an increase or decrease of the carrying amount of the obligation and related asset, according to IAS 38, “Intangible assets”. Any decrease in the provision, and any decrease of the asset that may exceed the carrying amount of said asset is immediately recognized in the income statement.

If the review of the estimated obligation results in the need to increase the provison and, accordingly, increase the carrying amount of the asset, the Group’s entities will also take into consideration if said increase corresponds to an indicator that asset has been impaired and, if so, impairment tests are carried out, according to the guidelines of IAS 36, “Impairment of assets” (Note 2.16).

2.23 Earnings per share

Basic and diluted earnings per share are calculated considering that the Group does not have financial instruments with dilutive effects, as shown below:

i) The numerator corresponds to the net profit of the period for the Group.

F-28

(All amounts are expressed in thousands of S/. unless otherwise stated)

ii) The denominator is the weighted average number of shares in issue at the date of the Group’s consolidated financial statements.

2.24 Capital

Common shares are classified as equity.

Incremental costs directly attributable to the issue of new shares or options are shown in equity, as a deduction, net of taxes, of the proceeds.

Where any Group company purchases the company’s equity shares (treasury shares), the consideration paid, including any directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the company’s equity holders until the shares are cancelled or reissued. Where such shares are subsequently reissued, any consideration received, net of any directly attributable incremental transaction costs and the related income tax effects, is included in equity attributable to the Group’s equity holders.

2.25 Revenue recognition

Revenue is measured at the fair value of the consideration received or receivable. Revenue is stated net of sales rebates, discounts and after eliminating sales between Group companies.

The Group recognizes revenue when the amount of revenue can be reliably measured; when it is probable that future economic benefits will flow to the entity; and when specific criteria have been met for each of the Group’s activities.

The Group’s revenue recognition policy is described as follows:

i) Revenue from construction activities -

Revenues from construction contracts are recognized using the percentage-of-completion method based on the costs incurred method or the units of work method, considering total costs and revenues estimated at the end of the project, in accordance with IAS 11, Construction Contracts. Under this method, revenues are determined based on the contract costs incurred in comparison to total contract costs, representing the profits that can be attributed to the portion of work completed.

Revenue is billed once approval is received by the owners of the work in progress.

With respect to services that have been provided but not billed, due to a lack of approval on behalf of owners the Company recognizes a deferred revenue liability for revenue with an increase in accounts receivable.

Accounts receivable derived from work services are shown net of the advances received from customers to the extent the related contracts include liquidation provisions.

ii) Revenue from engineering, advisory and consulting services -

Revenue from services is recognized in the accounting period when they are provided, based on the services performed to date as a percentage of the total services to be performed.

iii) Sales of real-estate properties -

Revenue from sales of real estate properties is recognized in the results of the period when sales occur, that is, when the properties are delivered and the risks and rewards inherent to ownership are transferred to the buyer and the collection of the corresponding receivables is reasonably assured.

F-29

(All amounts are expressed in thousands of S/. unless otherwise stated)

iv) Revenue from IT Services -

The sale of computer equipment includes some services to be provided in a subsequent date to the asset sale as installation and maintenance. When sales agreements include multiple elements, the amount of the revenue is attributed to each element based on the related fair values. The fair value of each element is determined based on the market price prevailing for each element when sold separately. Revenue derived from computer equipment is recognized when the related risks and rewards are transferred to the customer, which occurs upon delivery. Revenue relating to each service element is recognized as a percentage of the total services to be performed during the period of service.

v) Interest income -

Revenue from interest is recognized on a time-proportion basis, using the effective interest method.

vi) Dividend income -

Dividend income is recognized when the right to receive payment is established.

vii) Revenue for concession services -

Revenue for concession services is recognized in the accounting period when they are provided, based on the services performed or as a percentage of the total services to be performed (see Note 2.5).

2.26 Construction contract costs

Construction contract costs are recognized as an expense in the period in which they are incurred.

Contract costs include all direct costs such as materials, labor, subcontracting costs, manufacturing and supply costs of equipment, start-up costs and indirect costs. Periodically, the Company evaluates the reasonableness of the estimates used in the determination of the percentage-of-completion. If, as a result of this evaluation, there are modifications to the revenue or cost previously estimated, or if the total estimated cost of the project exceeds expected revenues, an adjustment is made in order to reflect the effect in results of the period in which the adjustment or loss is incurred.

When the outcome of a construction work cannot be estimated reliably, the revenue of the contract is recognized only up to the amount of the contractual costs incurred and that are likely to be recovered.

Changes in contract relating to the work to be performed, lawsuits and payment of incentives are included in the revenue from the contract to the extent that they have been agreed with the client and can be measured reliably.

2.27 Leases

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are charged to the profit or loss of the period on a straight-line basis over the period of the lease.

The Group leases certain property, plant and equipment. Leases of property, plant and equipment where the Group has substantially assumed all the risks and rewards of ownership are classified as finance leases. Finance leases are capitalized at the lease’s commencement at the lower of the fair value of the leased property and the present value of the minimum lease payments.

Each lease payment is allocated between the liability and finance charges in order to obtain a constant rate on the balance pending payment. The corresponding rental obligations, net of finance charges, are included

F-30

(All amounts are expressed in thousands of S/. unless otherwise stated)

in other long-term payables. The interest element of the finance cost is charged to the income statement over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant and equipment acquired under finance leases are depreciated over the shorter of the useful life of the asset and the lease term.

2.28 Dividend distribution

Dividend distribution to the Company’s shareholders is recognized as a liability in the financial statements in the period in which the dividends are approved by the Company’s shareholders.

2.29 Contingent liabilities and assets

Contingent liabilities are not recognized in the financial statements, they are only disclosed in the Notes to the financial statements, unless it is probable that the use of resources is remote. Contingent assets are not recognized in the financial statements and are only disclosed when it is probable that an inflow of resources will flow to the Company.

2.30 Significant non-operating items

Significant non-operating items are disclosed in the financial statements when they are necessary to provide a better understanding of the Group’s financial performance. These material items are income or expenses shown separately due to the significance or their nature or amount.

2.31 Standards, amendments and interpretations not yet effective

a) Standards, amendments and interpretations adopted by the Group

There are no IFRSs or IFRIC interpretations that are effective for the first time for the financial year beginning on or after January 1, 2012 that would be expected to have a material impact on the Group.

b) Standards, amendments and interpretations issued but not yet effective for 2012 and which were not early adopted -

The following standards are relevant to the Group’s activities:

• IFRS 7, ‘Financial instruments: Disclosures’ as amended in October 2010. The IASB modified the disclosures required so that the users of the financial statements may assess the risk exposure related to financial asset transfers and the effect of these risk on the entity’s financial position. For the Company, this amendments will come into effect on January 1, 2013.

• IFRS 9, ‘Financial instruments’, addresses the classification, measurement and recognition of financial assets and financial liabilities. It replaces the parts of IAS 39 that relate to the classification and measurement of financial instruments. IFRS 9 requires financial assets to be classified into two measurement categories: those measured at fair value and those measured at amortized cost. The classification depends on the entity’s business model for managing its financial instruments and the contractual cash flow characteristics of the instrument. For financial liabilities, the standard retains most of the IAS 39 requirements. Application of IFRS 9 will be mandatory from January 1, 2015.

• IFRS 10, ‘Consolidated financial statements’, replaces IAS 27 and SIC 12 and builds on existing principles by identifying the concept of control as the determining factor in whether an entity should be included within the consolidated financial statements of the parent company. The standard provides additional guidance to assist in the determination of control where this is difficult to assess. IFRS 10 will be applied with effect from January 1, 2013.

F-31

(All amounts are expressed in thousands of S/. unless otherwise stated)

• IFRS 11, ‘Joint arrangements’, which replaces IAS 31 and amends the classification of joint arrangements in only two categories (joint operations and joint ventures), depending on whether the investors have contractual rights and obligations on the assets and liabilities of the arrangement (joint operation) or whether investors have a residual right on the equity of the arrangement (joint venture). This standard discontinues the application of proportional consolidation method. IFRS 11 will be applied with effect from 1 January 2013.

• IFRS 12, ‘Disclosures of interests in other entities’ includes the disclosure requirements for all forms of interests in other entities, including joint arrangements, associates, special purpose vehicles and other off balance sheet vehicles. IFRS 12 will be applied with effect from January 1, 2013.

• IFRS 13, ‘Fair value measurement’, aims to improve consistency and reduce complexity by providing a precise definition of fair value and a single source of fair value measurement and disclosure requirements for use across IFRSs. The requirements do not extend the use of fair value accounting but provide guidance on how it should be applied where its use is already required or permitted by other standards within IFRSs. The application of this standard is mandatory from January 1, 2013.

• Amendment to IAS 1, ‘Presentation of financial statements’ relating to other comprehensive income. The major change resulting from this amendment is the requirement for entities to group the items of “other comprehensive income” (OCI) depending on whether they are reclassifiable or not to the income statement. These amendments do not specify which items should be incuded in OCI.

• IAS 19, ‘Employee benefits’ was amended in June 2011 by the IASB. The amendments eliminate the corridor approach and recognize financial expenses on a net basis. This amendments will be effective for the Company on January 1, 2013.

• IAS 27, ‘Separte financial statements’. It was amended in May 2011 by the IASB under the new heading ‘Separate financial statements’. The new standard include the alignment of the separate financial statements which remain effective once the provisions of control were included in IFRS 10. For the company, this standard is effective as of January 1, 2013.

• IAS 28, ‘Investments in Associates and Joint Ventures’. It was amended in May 2011 by the IASB. The new standard includes guidelines to recognize joint ventures and associates under the equity method. This standard will become effective for the Company on January 1, 2013.

The Group has carried out an initial assessment of the impact of these new standards on its financial position and results. The adoption of IFRS 11 required a more detailed analysis of the effect, given the Groups participation in several arrangements with third parties, in this case, joint operations. However, after such initial assessment, Management considers that the standard will not have a material impact on the Group’s financial position or performance because the Group only has joint operations and does not apply the proportional consolidation method as defined under IFRS 11. The accounting to be applied to these joint operations under IFRS 11 is similar to the accounting previously applied to these arrangements under IAS 31. The Group recognizes, in relation to its interest in a joint operation, its assets and liabilities, including its share of any asset or liability held jointly with its partner as well as its share of revenue and expense from the joint operation.

The other standards described above will only affect certain disclosures in the financial statements.

There are no other IFRS or IFRIC interpretations that are not yet effective that would be expected to have a significant impact on the Group’s financial statements.

F-32

(All amounts are expressed in thousands of S/. unless otherwise stated)

2.32 Reclassifications

The following reclassifications have been carried out in the financial statements of 2011 to make them comparable with the balances of the financial statements of 2012:

• The cost of the investment in Shopping Mall Parque El Agustino classified in 2011 under property, plant and equipment, owned by subsidiary Viva GyM and amounting to S/.36.5 million (Note 14),was reclassified to Investment property in 2012.

• The balances of work in progress—construction and rights to be billed were classified in 2011 in the statement of financial position as inventories and trade accounts receivable, respectively. In 2012 they were reclassified as “work in progress due from customers” (Note 9).

3 FINANCIAL RISK MANAGEMENT

Financial risk management is carried out by the Group’s Management. Management oversees the general management of risks in specific areas, such as exchange rate risk, price risk, interest rate risk, credit risk, the use of derivative and non-derivative financial instruments and the investment of excess liquidity as well as financial risks and carries out periodic supervision and monitoring.

3.1 Financial risk factors

The Group’s activities expose it to a variety of financial risks: market risk (including currency risk, price risk, fair value interest rate risk and cash flow interest rate risk), credit risk and liquidity risk. The Group’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Group’s financial performance. The Group uses derivative financial instruments to hedge certain risk exposures in one of its subsidiaries and considers the use of other derivatives, in the event that it identifies risks that may generate an effect for the Group in the short- and medium-term.

a) Market risks -

i) Foreign exchange risk -

The Group is exposed to exchange rate risk as a result of the transactions carried out locally in foreign currency and due to its operations abroad. As of December 31, 2012, this exposure is mainly concentrated in fluctuations of the U.S. dollar and Chilean pesos. As of December 31 and January 1, 2011, it is mainly concentrated in U.S. dollars.

Management has set up a policy to require Group companies to manage their foreign exchange risk against their functional currency. The Group companies are required to hedge their entire foreign exchange risk exposure with the Group treasury. To manage their foreign exchange risk arising from future commercial transactions and recognized assets and liabilities, Group companies use forward contracts, entered into with Group treasury. Foreign exchange risk arises when future commercial transactions or recognised assets or liabilities are denominated in a currency other than the entity’s functional currency.

In order to reduce its exposure, efforts are made to maintain an appropriate balance between assets and liabilities, as well as between income and expenses in foreign currency. It should be Noted that Management has alternatively approved a policy to use derivative financial instruments to protect from foreign exchange risk.

As of December 31, 2012, the consolidated statement of financial position includes assets and liabilities in foreign currency equivalent to S/.1,673 million and S/.1,568 million, respectively (S/.1,040 million and S/.1,374 million, respectively, as of December 31, 2011).

F-33

(All amounts are expressed in thousands of S/. unless otherwise stated)

The Group’s exchange gains and losses for 2012 amounted to S/.264 million and S/.243 million, respectively (S/.166 million and S/.164 million respectively in 2011).

If at December 31, 2012, the new Peruvian sol had strengthened/weakened by 10% against the U.S. dollar, with all variables held constant, the pre-tax profit for the year would have increased/decreased by S/.2 million (S/.0.19 million in 2011 and S/.0.82 million in 2010).

ii) Price risk -

The Company is exposed to the risk of prices of construction materials because steel is a major component of cost associated with the commodities necessary to provide its services, which is managed via negotiations with the respective suppliers. No significant liabilities relating to the purchase of commodities have been shown at December 31, 2012, 2011 and 2010; accordingly, the Company has not considered it relevant to include a sensitivity analysis of the effect of commodity price fluctuations on its performance.

Also, the Company is exposed to the risk of prices of services provided as a result of the concessions it has signed ( See Note 2.5 b-i). The regulated rate system, applicable to the Group concessions, Sets maximum rates (agreed in local currency) for each concession. This rate will be regularly adjusted every 12 months and in the event that more than 10% variance occurs from the last regular price adjustment, the rate can be modificed on an exceptional basis.

At December 31, 2012, 2011 and 2010, the maximum rate has been collected.

Concessions maintain an ongoing monitoring and adjustment of its revenues to make sure their annual billing do not exceed the maximum rate allowable.

iii) Cash flow and fair value interest rate risk -

The Group’s interest rate risk mainly arises from its long-term borrowings. Borrowings issued at variable rates expose the Group to cash flow interest rate risk. Borrowings issued at fixed rates expose the Group to fair value interest rate risk on its liabilities. Group policy is to maintain most of its borrowings in fixed rate instruments; 86% of total debt in 2012 (85% in 2011) was contracted at fixed rates. During 2012 and 2011 the Group’s borrowings at variable rates were denominated in U.S. dollars and the Group policy is to manage this risk by using interest-rate swaps, which are recognized under hedge accounting.

Management considers it unnecessary to prepare a sensitivity analysis of the variable-rate debt and the variable portion of the hedging derivative because it only comprises a 14% of the total debt for 2012 (15% in 2011) and any increase or decrease in interest rate would not have a material effect on the Group’s results. No relevant hedge ineffectiveness occurred in fiscal 2012 and 2011.

b) Credit risk -

Credit risk arises from cash and cash equivalents and deposits with banks and financial institutions, as well as customer credit counterparties, including the balances outstanding of accounts receivable and committed transactions. For banks and financial institutions, only independently rated parties with a minimum rating of ‘A’ are accepted. The Management of each of the Group’s companies evaluate the credit quality of the client taking into consideration its financial position, past experience and other factors. Individual risk limits are set based on internal or external ratings in accordance with limits set by the board. The utilization of credit limits is regularly monitored.

With respect to loans to related parties, the Group has measures in place to ensure the recovery of said loans through the controls maintained by the Corporate Finance Management and the performance evaluation conducted by the Board.

F-34

(All amounts are expressed in thousands of S/. unless otherwise stated)

No credit limits were exceeded during the reporting period, and Management does not expect the Group to incur any losses from non-performance by these counterparties.

c) Liquidity risk -

Prudent liquidity risk implies maintaining sufficient cash and cash equivalents, the availability of funding through an adequate number of sources of committed credit facilities and the capacity to close out positions in the market. In this sense, the Group has no significant liquidity risks given the fact that historically its operating cash flows have enabled it to maintain sufficient cash to meet its obligations.

Group Corporate Finance monitors rolling forecasts of the Group’s liquidity requirements to ensure it has sufficient cash to meet operational needs while maintaining sufficient headroom on its undrawn committed borrowing facilities (Note 16), so that the Group does not breach borrowing limits or covenants, where applicable, on any of its borrowing facilities. Less significant financing transactions are controlled by the Finance Management of each subsidiary.

Such forecasting takes into consideration the Group’s debt financing plans, covenant compliance, compliance with internal statement of financial position ratio targets and, if applicable, external regulatory or legal requirements; for example, currency restrictions.

Surplus cash held by the operating entities over and above the balance required for working capital management are invested in interest-bearing checking accounts or time deposits, selecting instruments with appropriate maturities and sufficient liquidity.

The following table analyzes the Group’s financial liabilities into relevant maturity groupings based on the remaining period from the date of the statement of financial position to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows.

	Less than 1 year		From 1 to 2 years		From 2 to 5 years		Over 5 years		Total

		1,756,628		150,084		217,466		96,286		2,220,464

3.2 Capital management -

The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders, benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

F-35

(All amounts are expressed in thousands of S/. unless otherwise stated)

In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

The Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings (including current and non-current borrowings), less cash and cash equivalents. Total capital is calculated as ‘equity’ as shown in the consolidated statement of financial position plus net debt.

As of December 31, 2011, no gearing ratio was part of the analysis because cash surpluses were higher than financial obligations and equity had not been used to secure compliance with financial obligations as it is shown in the table below. As of December 31, 2012, due to the fact that the Company has acquired significant borrowings, the Company’s strategy was to maintain a gearing ratio between 0.03 and 1.00.

As of December 31, 2011 and 2012 the gearing ratio was as follows:

	December 31, 2011			December 31, 2012
	S/.000			S/.000
Total borrowing		529,848			845,474
Less: Cash and cash equivalents		(658,187	)		(780,114	)
Net debt		(128,339	)		65,360
Total equity		1,453,086			1,776,890
Total capital		1,324,747			1,842,250
Gearing ratio		0.00			0.04

3.3 Fair value estimation -

For the classification of the type of valuation used by the Group for its financial instruments at fair value, the following levels of measurement have been established.

• Level 1: Measurement based on quoted prices in active markets for identical assets or liabilities.

• Level 2: Measurement based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability (level 1), either directly (that is, as prices) or indirectly (that is, derived from prices).

• Level 3: Measurement based on inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs, generally based on internal estimates and assumptions of the Group).

The only financial instruments measured at fair value by the Group are the interest rate swaps signed with subsidiary GMP S.A., by which a variable-interest instrument is changed to a fixed interest rate and forward foreign exchange contracts signed by subsidiaries GyM Ferrovías S.A. and Viva GyM S.A. to hedge its exposure to changes in the exchange rate of the Euros and U.S. dollars. The measurement at fair value of these instruments corresponds to the characteristics of Level 2 and has been determined based on the present value of discounted future cash flows applied to the interest-rate change projections of Citibank New York.

The investment maintained in Transportadora de Gas del Perú S.A. (TGP) has been recorded at cost; however, the fair value of this investment approximates its cost.

The carrying amount of cash and cash equivalents corresponds to its fair value. The Company considers that the carrying amount of the short- and long-term accounts receivable and payable is similar to their fair values. The fair value of financial liabilities, disclosed in Note 16-c), has been estimated by discounting the future contractual cash flows at the interest rate currently prevailing in the market and which is available to the Company for similar financial instruments.

4 CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

Estimates and judgments used are continuously evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

4.1 Critical accounting estimates and assumptions

The Group makes estimates and assumptions concerning the future economic performance. These estimates and assumptions are required to be made because the information used in the presentation of the financial information is currently not available, is dependent on future events, or cannot be calculated with a high degree of accuracy. The resulting accounting estimates will, by definition, seldom equal the related actual results. If outcomes in the next fiscal year are much different than current assumptions a material adjustment might be required to the carrying amount of the assets and liabilities. However, Management considers that the estimates and assumptions do not have a significant risk of causing a material adjustment to the balances of assets and liabilities in the following year.

a) Goodwill impairment reviews -

Goodwill arises from the acquisition of subsidiaries and represents the excess of the cost of acquisition over the fair value of the acquiree’s net identifiable assets at the acquisition date. At December, 31, 2012 the Group accounted S/.91,929 thousand of goodwill on the consolidated statement of financial position. (Note 15-a).

Impairment reviews are undertaken annually to determine if goodwill arising from business acquisitions has suffered any impairment, in accordance with the policy described in Note 2.15-a). For this purpose, goodwill is attributed to the different CGUs to which it relates. The recoverable amount of the CGUs has been determined based on its value-in-use calculations. This evaluation requires the exercise of Management’s professional judgment to analyze any potential indicators of impairment as well as the use of estimates in determining the value in use, including the preparation of future cash flows, macro-economic forecasts as well as defining the interest rate at which said cash flows will be discounted.

Value in use is usually determined on the basis of discounted estimated future net cash flows. Determination as to whether and how much an asset is impaired involves management estimates on highly uncertain matters such as future commodity prices, the effects of inflation on operating expenses, discount rates, production profiles and the outlook for global or regional market supply-and-demand conditions for crude oil, natural gas and refined products.

If the Group experiences a significant drop in revenues or a drastic increase in costs or changes in other factors the fair value of business units might decrease. If management determines the factors that reduce the fair value of the business are permanent, those economic factors will be taken into consideration to determine the recoverable amount of the business units and, therefore, goodwill may be deemed to be impaired, which may cause a writedown of goodwill to be necessary.

Based on the impairment testings performed by Group Management, no goodwill impairment losses were required to be recognized because the recoverable amount of the CGUs subject to testing was substantially higher than their related carrying amounts.

(All amounts are expressed in thousands of S/. unless otherwise stated)

The most significant assumptions are gross margin, growth rate and discount rate which are included in Note 15. We have performed a sensitivity analysis on the gross margin and discount rate which is included below.

a.) Gross margin

The Group’s fair value is significantly above its book value and if the gross margin was adjusted down by 10% the fair value would be 144% higher than the book value and if the gross margin was adjusted up by 10% the fair value would be 151% higher than book value. Therefore the Group’s businesses would still be greater than the book value even under a significant decline in the Group’s gross margin and the Group would not need to impair its goodwill.

b.) Discount Rate

The Group’s fair value is significantly above its book value and if the discount rate was adjusted down by 10% the fair value would be 136% higher than the book value and if the discount rate was adjusted up by 10% the fair value would be 93% higher than book value. Therefore the Group’s businesses would still be greater than the book value even under a significant upward adjustment to the discount rate in value and the Group would not need to impair its goodwill.

b) Taxes -

Determination of the tax obligations and expenses requires interpretations of the applicable tax laws and regulations. The Company seeks legal tax counsel’s advice before making any decision on tax matters. Although Management considers its estimates to be prudent and appropriate, differences of interpretation may arise with the Peruvian Tax Authorities which may require future tax adjustments.

Deferred tax assets and liabilities are calculated by taking the temporary differences of the tax basis of assets and liabilities and the financial statement basis using the tax rates in effect for each of the years in which the difference is expected to reverse. Any change in tax rates will affect the deferred tax assets and liabilities. This change will be recognized in income in the period the change takes effect.

Management makes estimates for our deferred income tax valuation allowance. This allowance may be increased or decreased if the Group determines it to be more likely than not that our valuation allowance needs to be adjusted. If a tax position is not more likely than not to ultimately be realized, no tax benefit is recorded.

The Group bases its estimates for the valuation allowance on all available evidence which includes historical data, projected income, current operations and tax planning strategies. The deferred tax asset is supported by the assumption that the Group will continue to generate income in the future. If management determines in the future revenues will not be sufficient to cover the deferred tax asset, it would adjust the valuation account for deferred tax income.

c) Percentage of completion revenue recognition -

Revenue from construction contracts is recognized under the percentage-of-completion method which requires the final margin from construction contracts to be estimated. Projections of these margins are performed by Management based on work execution budgets and adjusted periodically based on updated information reflecting the actual performance of work. The estimated contract revenue and total cost estimates are reviewed often as work advances and change orders are initiated and approved. In this regard, Management considers that the estimates made at the year-end closing are reasonable. When unapproved change orders are presented, revenue is recognize equal to costs incurred (no profit component recognized) until the additional work has been approved.

F-38

(All amounts are expressed in thousands of S/. unless otherwise stated)

Contract revenue is recognized as revenue in the income statement in the accounting periods in which the work is performed. Contract costs are recognized as cost of sales in the income statement in the accounting period in which the work to which they relate is performed. However, any expected and probable excess of total contract costs over total contract revenue for the contract is recognized as an expense immediately. Furthermore, any changes in contract estimates are recognized as a change in accounting estimates and recognized in the period the change is made and in future periods if applicable. In certain construction contracts, the terms of these agreements allow for an amount to be withheld by the customers until construction has been completed. Under these contracts the full amount may not be recognized until the next operating cycle. As of December 31, 2012, 2011 and 2010, a sensitivity analysis was performed considering a 10% increase/decrease in the Group’s gross margins, as follows:

	2010			2011			2012
	S/.000			S/.000			S/.000
Sales		1,605,181			2,650,334			3,341,539
Gross profit		206,063			289,813			371,852
%		12.84			10.93			11.13
Over 10%		14.12			12.03			12.24
		226,669			318,794			409,037
Increase in profits before taxes		20,606			28,981			37,185
Less 10%		11.55			9.84			10.02
		185,457			260,832			334,667
Decrease in profit before taxes		(20,606	)		(28,981	)		(37,185	)

d) Provision for well closure costs -

The Company estimates the present value of its future obligation for well closure costs, or “ well closure liability, and increases the carrying amount of the asset that will be withdrawn in the future and that is shown under the heading of intangibles in the statement of financial position. The discount rate used for the present value calculation was 1.78% based on the 10 year bond rate as of December, 2012. On December 31, 2012 the present value of the estimated provision for closure activities for the 85 wells amounted to S/.4.9 million. Subsequently, this liability is attributed to profit or loss during the useful life of the assets that gave rise to it. The well closure liability is adjusted to reflect the changes that resulted from the passage of time and from revisions of either the date of occurrence or the amount of the present value of the obligations originally estimated. With a discount rate of 1.78% the Company’s intangible balance isS/. 4.896,747. If the discount rate was adjusted down by 10% the intangible balance would be S/. 4’945,264and if the discount rate was adjusted up by 10% the intangible balance would be S/. 4’848,910.

During 2012, the Company recorded S/.4.9 million, charged to the intangible asset account, credited to the well closure liability. This is to reflect estimated obligations to close 70 productive wells included in the service agreements for Blocks I and IV. This provision is increased monthly, charged to results, on an incremental value basis.

4.2 Critical judgments in applying the entity’s accounting policies

For the transactions recognized in the financial statements of 2012 and 2011 no special exercise of judgment was required, except for the accounting treatment of the acquisition of the CAM Group described in the following paragraphs:

CAM acquisition -

Under IFRS 3, an entity recognizes a profit on an acquisition when the fair value of the assets acquired, net of the liabilities assumed exceeds the consideration paid. This accounting standard presumes that recognition of a

F-39

(All amounts are expressed in thousands of S/. unless otherwise stated)

profit on a business acquisition is unusual; therefore, it requires the buyer to review the determination of the fair values of the acquired assets, liabilities and price paid before recognizing any gains. Furthermore, IFRS 3 authorizes a review period of 12 months from the acquisition date for an entity to adjust the determination of the fair values of the acquired assets and liabilities and, therefore, adjust the goodwill or gain generated from the acquisition, as applicable.

On February 24, 2011, the Group acquired the CAM Group and as a result of the process of allocating the purchase price paid, the fair value of the assets acquired, net of the liabilities assumed, was determined to have exceeded the consideration paid by S/.45.2 million. At the date of issue of the financial statements, the 12-month period requirement for fair value review had been met and Management considers that it has reasonably reviewed the values attributable to the assets and liabilities of the business acquired; accordingly, it has completed the process of allocating the consideration paid, and has therefore, recognized the above-mentioned profit on acquisition in the year-end profit or loss.

In this context, Management considers that the profit on acquisition resulted from a bargain purchase in which the selling party, an entity with different business units additional to the business sold, was required to dispose of its investment because of a restructuring process intended to, among other matters, focus on business activities other than the CAM Group’s current businesses.

Estimated useful life of machinery and equipment -

The Company reviews on an annual basis the useful lives of its machinery and equipment. The evaluation of the useful lives is made based on the hours of use and is performed by the technical internal area. This estimation of work hours is performed based on historical data considering the estimated productive capacity of the asset and is expressed in a rate per unit of production or hour. Management determined not to change the useful life over the current year because, based on its own assessments, the useful lives already reflected the current economic conditions of the Company’s operating environment.

5 SEGMENT REPORTING

Operating segments are reported consistently with the internal reports that are reviewed by the Corporate General Manager, who is the chief operating decision maker, responsible for allocating resources and evaluating the performance of each operating segment.

The Group’s operating segments are assessed by the activity of the following business units: (i) engineering and construction, (ii) infrastructure, (iii) real estate, (iv) technical services and (v) the operation of the Parent Company.

During 2012, in line with the Group’s business monitoring strategy, Corporate Management has revised its operating segments and has decided to consider the operations of subsidiary GMP within the infrastructure segment, which includes the following business units (i) energy, (ii) tolls roads, (iii) mass transit; and (vi) water treatment. As a result of the new regrouping the services segment has been renamed as technical services segment.

Given this change, prior-year comparative information has been restated to reflect the revised structure of operating segments.

As set forth under IFRS 8, reportable segments by significance of income are: ‘engineering and construction’ and ‘technical services’. However, the Group has voluntarily decided to report on all its operating segments as detailed in this Note.

Until 2010 the Group’s revenues were substantially derived from local operations. In 2011, with the purchase of the CAM subsidiary and Vial y Vives (Note 28), the revenues derived from foreign operations (Chile, Brazil, Colombia) comprise 17.21% of the Group’s total revenue in 2012 (14.93% in 2011).

F-40

(All amounts are expressed in thousands of S/. unless otherwise stated)

Inter-segmental sales transactions are entered into at prices that are similar to those that would have been agreed with unrelated third parties. Revenues from external customers reported to the Corporate General Management are measured in a manner consistent with the preparation basis of the financial statements.

Group sales and receivables are not concentrated in a few customers.

The following segments set forth the principal activities of each of the Group:

a) Engineering and construction: This segment includes: (i) engineering, from traditional engineering services such as structural, civil and design engineering, and architectural planning to advanced specialties including process design, simulation, and environmental services; (ii) civil works, such as the construction of hydroelectric power stations and other large infrastructure facilities; (iii) electromechanic construction, such as concentrator plants, oil and natural gas pipelines, and transmission lines; (iv) building construction, such as office buildings, residential buildings, hotels, affordable housing projects, shopping centers and industrial facilities; (v) contract mining, such as earthworks, blasting, loading and hauling ore.

b) Infrastructure: The Group has long-term concessions or similar contractual arrangements in Peru for three toll roads, the Lima Metro, a waste water treatment plant in Lima, multiple fuel storage facilities, two producing oil fields, and a gas processing plant.

c) Real Estate: The Group develops and sells homes targeted to low- and middle-income population sectors which are experiencing a significant increase in disposable income, as well as, to a lesser extent, office and commercial space.

d) Technical Services: The Group provides: (i) operation and maintenance services for infrastructure assets; (ii) information technology (IT) services, including IT outsourcing, systems integration, application outsourcing and business process outsourcing services; and (iii) electricity networks services (maintenance).

e) Parent Company Operation: The Holding provides managing, logistics and accounting services, among others, to the different related entities of the Group.

In seeking to mitigate the exposure resulting from the expenditures incurred in Euros to a foreign supplier for the purchase of the infrastructure required under the concession agreement signed between a subsidiary, GyM Ferrovías S.A., (see Note 2.5) and the Peruvian Government, this subsidiary entered into a cross currency swap contract by which the purchase of Euros at a future date is secured at a fixed exchange rate. This contract is accounted for as a fair value hedge by the Group and it recognizes the fair value of the financial instrument (cross currency swap) in profit or loss and, as a counterpart, it recognizes the fair value of the firm commitment associated with the contract with the foreign supplier. At December 31, 2012 the derivative financial instrument constitutes a liability at a fair value of S/.12.7 million.

6.2 Quality of financial assets -

The credit quality of financial assets that are neither past due nor impaired can be assessed by reference to external risk ratings (if available) or to historical information about counterparty default rates:

The credit quality of financial assets is presented as follows:

	December 31,
	2011		2012
	S/.000		S/.000
Cash and cash equivalents(*)
Banco de Crédito del Perú(A+)		269,982		426,762
Banco Continental(A+)		145,266		156,419
Banco Santander(Chile)(A)		—		40,745
Banco Interbank(A)		60,336		33,864
Banco Scotiabank(A+)		19,730		26,648
Banco de la Nación(A)		33,006		24,784
Banco de Chile(A+)		24,045		16,828
Banco Santander(A)		61,873		9,024
Citibank(A)		3,158		4,610
Banco BCI(Chile)(A)		—		3,451
Banco Interamericano de Finanzas(A)		2,543		30
Other lesser amounts		36,195		33,859
Total cash and cash equivalent		656,134		777,024

The ratings in the above table “A and A+” represent high quality credit ratings. For banks located in Peru, the ratings were derived from risk rating agencies authorized by the Banking and Insurance Superintendency of Peru (Superintendencia de Banca, Seguros y AFP). For banks located in Chile, the ratings were derived from risk rating agencies authorized by the Stock and Insurance Superintendency of Chile (Superintendencia de Valores y Seguros).

F-52

(All amounts are expressed in thousands of S/. unless otherwise stated)

(*) The rest of cash equivalents in the statement of financial position corresponds to cash.

The credit quality of customers is assessed in three categories (internal classification):

A: new customers/related parties (less than 6 months),

B: existing customers/related parties (with more than 6 months of trade relationship) with no previous default history; and

C: existing customers/related parties (with more than 6 months of trade relationship) with previous default history.

At December 31, 2012 and 2011 the majority of the Group’s portfolio has been risk-rated as category B. Also, of the total number of accounts in compliance with contract terms and conditions, none of them have been re-negotiated.

With respect to available-for-sale financial assets, the counterparty held an external credit rating of AAA at December 31, 2012 and 2011.

This account comprises:

	December 31,
	2011		2012
	S/.000		S/.000
Invoices receivable		488,310		444,593
GyM Ferrovías S.A. Collection Rights		—		305,887
		488,310		750,480
Less: non-current portion		—		(305,887	)
Current trade accounts receivable		488,310		444,593

The fair value of receivables is similar to their carrying amount since their average collection turnover is less than 60 days. These receivables are of current maturity, are not interest-bearing and have no specific guarantees.

Invoices receivable are related to percentage of completion estimates. As of December 31, 2012 and 2011, trade receivable balances are shown net of the advances received from customers of S/.849 million and S/.327 million, respectively. These advances are substantially related to the subsidiary GyM S.A. and their

F-53

(All amounts are expressed in thousands of S/. unless otherwise stated)

terms vary based on each contract. At December 31, 2012, a significant portion of these advances of S/.555 million corresponds to the funds given by certain customers with which a monthly revolving advances system has been agreed that are settled with the billing of the immediately previous month. Other advances that are netted from accounts receivable correspond to funds netted gradually as services are provided; which in the event of an anticipated termination of the contractual relationship will be offset with the balances due for work progress.

Long-term accounts receivable comprise the collection rights of GyM Ferrovías S.A., which under the concession signed with the Peruvian Government comprising Line 1 of the Lima Metro/(train line) is required to acquire, on its behalf, certain infrastructure needed for the implementation of the transport system to be operated once completed. This account will be amortized with the cash flows resulting from the consideration to be received by the subsidiary at the inception of the concession under the “price per kilometer traveled” (PKT). For this purpose, the subsidiary has applied certain criteria to determine the amount of the interest to be accrued on these balances and the beginning of this amortization. These balances bear interest at a 7.7% rate and their amortization is expected to begin in 2015 at the time the infrastructure begins operation. Additionally, these balances also include the collection rights of concessions related to Survial S.A., Canchaque S.A.C. and La Chira S.A. (see Note 2.5-a).

The aging detail of trade accounts receivable is as follows:

	December 31,
	2011		2012
	S/.000		S/.000
Current		351,116		436,215
Past due up to 30 days		89,106		153,440
Past due for over 30 days		48,088		160,825
		488,310		750,480

As of December 31, 2012, trade accounts receivable totalling S/.314 million (S/.137.1 million as of December 31, 2011) are past due but not impaired, and the customers do not have a historical record of default.

The maximum exposure to credit risk at the reporting date is the carrying amount of the accounts receivable.

At December 2012, the Group recorded in profit or loss for the period an impairment of trade accounts receivable amounting to S/.2.7 million resulting from the assessment of the customer portfolio of subsidiary CAM Holding S.P.A, which, after a specific review and assessment of balances outstanding by Management, has certain customers who were undergoing financial difficulties and shown payment delinquency during 2012. Such provision for impairment shows no movement from the date of CAM Holding acquisition.

9 WORK IN PROGRESS DUE FROM CUSTOMERS

This account comprises:

	December 31,
	2011		2012
	S/.000		S/.000
Rights receivable:		333,436		465,741
Work in progress		60,390		59,510
		393,826		525,251

F-54

(All amounts are expressed in thousands of S/. unless otherwise stated)

Rights receivable correspond to the unbilled rights for services rendered. Each month, under the percentage of completion method, the Company estimates the advancement of work to date. Based on its monthly estimates, the Company recognizes revenue. Until such revenue is billed, it is recorded in the account rights receivable.

The balance of work in progress includes costs that the Group incurred related to future activity on the construction contracts. Such contract costs are recognized as an asset since the costs will be recovered in the near future.

Accounts receivable from related parties mainly arise from sales transactions for goods and services with maturity periods of 60 days. Such accounts are non interest-bearing, because they have short-term maturities and do not require a provision for impairment.

Accounts payable to related parties mainly arise from transactions to provide services of engineering, construction, maintenance and others and have maturity periods of 60 days. Such accounts are not interest bearing because they are short-term.

Transactions with non-controlling interest are disclosed in Note 31.

These balances comprise additional investments established in the operating agreement and completed by Consorcio Terminales (a joint venture of the subsidiary GMP S.A.) for the modernization and extension of 9 terminals subject to the agreement. These investments which are presently works in progress will be transferred to Petróleos del Perú S.A.—Petroperú S.A., once a technical audit has been completed and after obtaining the written approval and accreditation of said institution; the value thus determined will be considered for billing. During fiscal 2012 and 2011, said Consortium has incurred additional investments of US$11.5 million and US$7.6 million, respectively; which will be collected over the effective period of the agreement, once Petróleos del Perú—Petroperú S.A., confirms the investment made as a result of technical audits.

General -

Other receivables do not present past due amounts or impairment and the non-current balances are supported by contractual agreements with third-parties and in the particular case of the fiscal credit, its maturity has been determined based on the period, estimated by Management for using said fiscal credit.

The fair value of other short - term accounts receivable is similar to their carrying amount due to the fact of short term maturity.

At December 31, 2012, the fair value of other accounts receivable from Petróleos del Perú S.A., originates from the subsidiary GMP S.A., does not bear interest and, therefore, was discounted at the market rate prevailing at the date of the disbursements, which on average is 6% per annum (5.26% in 2011). This rate corresponds to the weighted average borrowing rate of the subsidiary.

The maximum exposure to credit risk as of the date of the report is the carrying amount of each class of other accounts receivable mentioned. The Group does not request collaterals as guarantee.

In 2012 and 2011, additions to cost correspond to acquisition of fixed assets under finance leases or direct acquisition.

In 2012 the sale of fixed assets amounted to S/.23.5 million (S/.6.4 million in 2011), resulting in a profit of S/.1.2 million (profit of S/.0.7 million in 2011), which is shown in the income statement under “other (losses), gains, net”.

In 2012, the Group assessed the classification of certain ítems of property, plant and equipment based on their actual function. As a result, the Group identified the need to reclassify the value of property maintained by the subsidiary Viva GyM from property, plant and equipment to property investments for S/.36 million (S/.2.2 million land and S/.33.8 million building).

Depreciation charged for the year which is depreciation on fixed assets and investment properties is broken down in the income statement as follows:

	2011		2012

a) Goodwill -

Management reviews the results of its businesses based on the type of economic activity carried out. Economic activities which have given rise to goodwill in the Group are construction, electro-mechanical, engineering services and sale of IT equipment and services.

Goodwill per cash-generating unit is broken down as follows:

	December 31,
	2011		2012
	S/.000		S/.000
Construction—Engineering (Note 28 a)		—		53,654
Construction—Mining services (Note 28 b)		—		13,366
Construction—Electromechanical		20,737		20,737
Information goods and services (Note 28 d)		4,172		4,172
		24,909		91,929

Goodwill from the electromechanical engineering business corresponds to the acquisition in prior years of the subsidiary GMA S.A., which was later merged with subsidiary GyM S.A.

As a result of the impairment testing on goodwill performed by Management on an annual basis the recoverable amount of the related cash-generating unit (CGU) is determined based on its value in use. Value in use is determined based on the future cash flows expected to be generated by the assessed CGU. As a result of these assessments no provisons for impairment was required.

The main criteria used by the Group to determine the value in use are as follows:

	Mining construction services			Engineering construction			Electro- mechanical			IT equipment and services
2011 -
Gross margin		—			—			11.8	%		30.6	%
Growth rate		—			—			1	%		0	%
Discount rate		—			—			14	%		11.3	%
2012 -
Gross margin		10.2	%		38.9	%		11.15	%		34.92	%
Growth rate		5	%		5	%		1	%		1.6	%
Discount rate		14	%		12	%		14	%		11	%

A 14% rate was applied as the discount rate on the expected cash flows from the Electro-mechanical construction business unit.

These assumptions have been used for the analysis of each cash-generating unit (CGU) included in the operating segments for a period of 5 years and considering a recoverable residual value with no growth.

Management determines the budgeted gross margins based on past results and market development expectations. Average growth rates are consistent with those prevailing in the industry. Discount rates used are pre-tax and reflect the specific risk relating to the assessed CGUs.

b) Concessions -

The intangible asset includes the value attributable to the concession for the Ancón-Huacho-Pativilca road section of the Panamericana Norte highway. The intangibles arising from this concession at December 31,

F-68

(All amounts are expressed in thousands of S/. unless otherwise stated)

2012 mainly comprise the EPC contract for S/.98.2 million, highway improvement for S/.31.2 million, and equity trust for S/.7.9 million. By those contracts the Concessionaire has to construct, improve and rehabilitate the road infrastructure over the effective period of the concession.

Amortization of intangible assets -

The amortization of intangibles is distributed in the income statement as follows:

	2011		2012
	S/.000		S/.000
Cost of sales		44,553		60,517
Administrative expenses		6,670		10,968
		51,223		71,485

Block I and V

Comprising the investments in oil production, development and right to enter into concession agreements won by subsidiary GMP S.A., by which rights are obtained to oil and hydrocarbon exploration services for Blocks I and V, with a carrying amount at December 31, 2012 amounting to to S/.82.5 million and S/.9 million, respectively (S/.39.9 million and S/.8.2 million at December 31, 2011, respectively). These blocks are amortized from the period revenue is obtained from their operation until the corresponding agreements reach maturity, that is, in 2021 for Block I and 2023 for Block V.

a) Bank loans -

As of December 31, 2012 and 2011 this item comprises bank loans in local and foreign currency for working capital purposes. These obligations bear interest at fixed rates which fluctuate between 2% and 9% (2.5% and 7.7% in 2011).

In April 2005, the subsidiary Norvial S.A. signed with IFC and IDB, respectively, two agreements called “Loan Agreements” by which these multilateral financial institutions agree to provide financing for the engineering, construction, completion and acceptance of the works of the first stage of the Concession Agreement amounting to US$36 million (S/. 123.5 million). As of December 31, 2012, the balance of these loans amounts to S/.47.8 million (S/.50.8 million as of December 31, 2011).

Fair values are based on the cash flows discounted by using borrowing rates of 5.61% and 6.45%.

Subsidiary GMP S.A., maintains a loan with Citibank N.A. as per the loan agreement signed on September 19, 2008 (amended on August 29, 2012), which was applied to the financing of the construction,

F-69

(All amounts are expressed in thousands of S/. unless otherwise stated)

equipment and operating the new Gas Pariñas Plant of the subsidiary. The major amendments to the original agreement include: an increase in the financed amount to S/.72 million US$28 million, an extension of the repayment period and a reduction of accrued interest. The guarantees given to secure this obligation are: a mortgage on the land on which the Gas Pariñas Plant has been constructed; a pledge on the equipment and assignment of the cash flows to be obtained from sales to customers (Repsol, Llama Gas, Zeta Gas and Herco). Said loan reaches maturity in August 2020 , as per the new conditions agreed upon.

This debt bears interest at Libor (3m) + 1.75%, if the exchange rate, at the installment payment date, remains within the range from S/.2.60 to S/.2.75 per US$1 or (ii) 1.95%, if the above range is not maintained. In order to reduce the exposure to Libor variation, the Company signed an interest rate swap with Citibank N.A., which establishes a fixed rate of 4.80% or 5.05%, based on each of the above cases. At December 31, 2012, the balance of this loan is S/.69.2 million (S/.37.8 million as of December 31, 2011).

In September 2012 subsidiary Viva GyM S.A. has signed financial instrument contracts (forward foreign exchange contracts) to hedge the next 12 monthly foreign currency denominated cash disbursements to be provided by Banco de Crédito del Perú through a line of credit. The purpose of the hedge is to set a fixed exchange rate of the U.S. dollars to be received by the Company, with the loan proceeds obtained from BCP, and consequently, the Company would obtain a fixed amount in Peruvian nuevos Soles to cover the construction costs of a building (Torre Real 8) expressed in said currency.

The total amount subject to hedging is US$3.6 million (broken down in 12 monthly payments of US$300 thousand each). Given the fact that the hedged transaction is considered a highly probable transaction, the initial recognition of this transaction will not affect the the Company’s results for the year. Foreign exchange movements that may have an effect on the Company’s results may arise from the remeasurement of the obligation in foreign currency at each reporting date until its settlement.

The Company also obtained a loan in October 2012 from Banco Continental for a total S/.156 million (US$60 million) at a rate of 4.15%, with maturity in January 2013. This loan was acquired for working capital and the acquisition of new business from its subsidiary GyM Ferrovías S.A. and GyM S.A., respectively.

As of December 31, 2012, the Company maintains unused credit limits for S/.1,728 million, which expire within one year (S/.1,594 million as of December 31, 2011).

Legal Claims

Legal claims as of December 31, 2012 and 2011 comprise provisions for labor-related obligations and tax claims recognized by subsidiaries GyM S.A., GMP S.A. and CAM Chile amounting to S/.5 million, S/.3 million and S/.3 million, respectively, see Note 27.

GyM -SUNAT. These provisions have been accounted based on management estimates of the amounts the Company would most likely be required to pay for theses cases. Regarding the tax claims, due to the fact those amounts depend on the tax authority,the Group does not have an estimated timing of when these outflows will take place.

Contingent Liabilities CAM Chile and affiliates

In addition, in 2011, contingent liabilities were maintained from CAM Chile and affiliates involving services to be billed for S/.12.9 million and statutory bonuses and other workers’ benefits amounting to S/.11.5 million. In 2012, given the fact that the contingent liabilities became executable obligations, they were reclassified to other accounts payable. The outflow expected during 2013 amounts to S/.10.7 million and from 2014 to 2016 S/.11.9 million, S/.9.8 million and S/.2.8 million respectively.

Contingent Liabilities Vial y Vives

As a result of the due diligence process, certain labor contingent liabilities were recorded for the acquisition of 74% of the outstanding shares of Vial y Vives. Each of these contingencies was assigned a probability of occurrence based on management and attorney assessments. The expected outflows expected to take place in 2013 amounts to S./.11.1 million.

Provisions for the year for the acquisition of CAM

In 2012 the Company completed a reversal of approximately S/.68 million in provisions that had been accrued in conjunction with labor and tax contingencies identified in conjunction with the purchase price allocation relating to the 2011 acquisition of CAM Chile and affiliates. Such provisions were written off in 2012, as the related labor and tax contingencies expired during the year. (See Note 25).

F-73

(All amounts are expressed in thousands of S/. unless otherwise stated)

Provision for well closure

In 1994 and 1995 GMP S.A. (“GMP”) contracted with Perupetro to provide hydrocarbon extraction services in Block I and Block V located in northwestern Peru. The contract states that GMP is responsible for the permanent abandonment of the following wells:

(i) wells drilled by GMP that have not been productive; and

(ii) old wells that have been seized or produced during the term of the contracts and that have mechanical problems or that no longer have oil reserves.

The permanent abandonment of these wells will begin in 2013 and will be implemented based on the following prioritization:

(i) wells drilled by GMP in Block I and Block V that are not productive; and

(ii) productive wells operated by GMP that are currently abandoned due to mechanical problems, high water production, low oil production or wells with a level of uneconomical production reserves.

A preliminary estimate was made of the wells that should be permanently closed: 70 wells from Block I and 15 wells from Block V. The closure processes will start in 2013 and be completed in 2021 and 2023, respectively. As of December 31, 2012, the discounted value of the estimated provision for closure activities for the 85 wells amounted to S/.4.9 million at a discount rate of 1.78%. Management expects an outflow related to the provision recorded in 2013 amounting to S/.0.4 million and from 2014 to 2017 amounting to S/.0.5 million. We are under no obligation for the remaining 315 wells that are not currently in production.

It should be noted that at the end of the effective periods of the agreements for Blocks I and V, there will be greater information and certainty regarding the amount of wells that should be permanently closed.

As of December 31, 2011, in application of said policy, the Company maintained 200,000 shares as treasury shares; however, at December 31, 2012 the Company decided to change its policy because all shares were sold and no longer maintains the above-mentioned shares.

22 WORKERS’ PROFIT SHARING

As established under current legislation, workers’ profit sharing of Graña y Montero S.A.A., consortiums and local subsidiaries is 5% of the net income. This share is deductible for the purposes of income tax.calculation.

In the case of the Dominican Republic, workers’ profit sharing rate is 10%. In the specific case of Chile, workers’ profit sharing is a component of remuneration and not a determinable percentage of profit. In Brazil and Colombia workers’ profit sharing does not exist.

In 2012, workers’ profit sharing amounted to S/.22.7 million (S/.23.6 million in 2011).

The distribution of workers’ profit sharing in the income statement at December 31 is as follows:

25 OTHER INCOME AND EXPENSES

At the acquisition date of CAM (Note 28-c), as part of the purchase price allocation process and based on external lawyers reports, we accounted for S/.102.7 million for contingent liabilities mainly related to labor and tax issues considered as posible and probable as stated by IAS 37, which have expiration dates according to legal requirements between 2012 and 2016.

F-79

(All amounts are expressed in thousands of S/. unless otherwise stated)

At December 31, 2012 the amount recognized as other income and expenses amounted to S/.75,944 thousands (S/.3,616 thousands and S/.2,684 thousands in 2011 and in 2010, respectively). This primarily reflects the write-off of provisions that were recognized in 2011 for the business combination with CAM, the liabilities that expired according with the corresponding applicable laws in each country during the year amounting to S/.68 million relating to labor-related and tax contingencies (from Brazil and Colombia for S/.32 million and S/.8 million, respectively) and trade liabilities amounting to S/.28 million. The probability of payment became remote during the course of 2012, as the statute of limitations for such issues expired.

26 INCOME TAX EXPENSES

a) In accordance with current legislation, each Group company is individually subject to the taxes applicable to it. Management considers that it has determined the taxable income under the general regime of income tax in accordance with the current tax legislation in each country.

b) The income tax expense shown in the consolidated income statement comprises:

	2010		2011			2012
	S/.000		S/.000			S/.000
Current tax:
- Current tax on profit of the year		102,133		184,410			145,909

Total deferred tax		22,209		(41,795	)		8,666
Income tax expense		124,342		141,447			154,575

c) The Group’s income tax on profit before taxes differs from the theoretical amount that would have resulted from applying the weighted-average income tax rate applicable to the profit of the consolidated companies, as follows:

	2010			2011			2012
	S/.000			S/.000			S/.000

- Others		—			—			(2,447	)
Income tax charge		124,342			141,447			154,575

d) Peruvian tax authorities have the right to examine, and, if necessary, amend the income tax determined by the Company in the last four years, as from January 1 of the year after the date when the tax returns are filed (years subject to examination). Years 2008 through 2012 are subject to examination by the tax authorities. Since differences may arise over the interpretation by the tax authorities of the regulations applicable to the Company, it is not possible at present to estimate if any additional tax liabilities will arise as a result of any eventual examinations. Any additional tax, fines and interest, if they occur, will

F-80

(All amounts are expressed in thousands of S/. unless otherwise stated)

be recognized in the results of the period when such differences with the tax authorities are resolved. Management considers that no significant liabilities will arise as a result of these possible tax examinations.

e) As established under regulations in force in Peru, for purposes of determining income tax and the general sales tax, transfer pricing must be taken into account for operations with related parties and/or tax havens, which must have documentation and information supporting the methods and valuation criteria applied in their determination. Peruvian tax authorities are entitled to request such information from the taxpayer.

f) Temporary tax on net assets -

The temporary tax on net assets is applied to third category income generators subject to the Peruvian Income Tax General Regime. Effective 2012, the tax rate is 0.4%, applicable to the amount of the net assets exceeding S/.1 million.

The amount effectively paid may be used as a fiscal credit against payments on account of income tax under the General Regime or against the provisional tax payment of the income tax of the related period.

g) The weighted-average tax rate was 29.68% (29.61% in 2011). The increase in the effective rate as compared to the previous year is due to the effect of the permanent differences in the income tax calculation.

27 CONTINGENCIES, COMMITTMENTS AND GUARANTEES

As of December 31, 2012 the Group presents the following contingencies:

a) Tax contingencies -

During the course of 2012, Graña y Montero S.A.A. was subject to tax audit for fiscal 2007, 2008 and 2009. As a result of this tax records examination, the Peruvian tax authorities (SUNAT) have issued resolutions of determination and penalties against which the Company has filed the respective appeals, which are pending resolution and the outcome of which Management and legal counsel consider will be favorable.

As a result of this tax records examination for fiscal years 1999 and 2001 of subsidiary GyM S.A., SUNAT has issued resolutions of determination and penalties totaling S/.29 million.

The Company has made a provision of S/.5 million which is the best estimate of the expected future expenses to be incurred any potential tax contingency and is included in the account “Other provisions”. Management considers that the outcome of the remaining court actions will be favorable, based on the analysis of their characteristics, performed by its legal counsel.

b) Other contingencies -

As of December 31, 2012, civil court actions have been brought against the Company mainly relating to claims of Municipalities in respect of work execution with no municipal authorization and failure to pay municipal rights for S/.4.7 million (S/.7.7 million in 2011).

Also, similar actions have been brought against joint-controlled businesses in which the Company has an interest, mainly relating to work executed without the respective municipal authorization; these actions total approximately S/.0.8 million (S/.2 million in 2011).

The Company’s Management considers that the above-mentioned court actions will be declared unfounded, and therefore, no liabilities will arise in addition to those already paid as of December 31, 2012.

F-81

(All amounts are expressed in thousands of S/. unless otherwise stated)

In February 2003 the Company was served notice of General Management Resolution No.004-2003-GG-OSITRAN issued by the Peruvian regulator of infrastructure and public transport investment - (OSITRAN) by which payment of S/.250,000 plus interest was ordered on the grounds of alleged withholdings of the Transport Fund (Fondo Vial) by the Company. To date, the Company has challenged said resolution and the conciliation hearing date remains to be set by the Administrative Court. Management considers that the outcome of this claim will be favorable to the Company and will not affect future financial results.

c) Commitments and Guarantees

As of December 31, 2012, the Group maintains guarantee commitments with different financial institutions securing transactions for US$170.8 million and S/.6.3 million.

b) Acquisition of Stracon GyM -

On March 1, 2012 GyM obtained control over certain business which it carry jointly with an entity called Stracon S.A.C. (hereinafter Stracon), as well as the control over certain interests owned by Stracon both individually and with other partners.

This acquisition was made effective through an entity that GyM and Stracon formed for this purpose. In fact, both entities established Stracon GyM S.A. (hereinafter Stracon - GyM), over which GyM exercises control and to which both the above-mentioned companies contributed with equity packages comprising various assets and liabilities associated with the mining industry.

This acquisition is part of the Group’s strategy to group in one single entity all businesses related to the mining industry, including existing businesses that were conducted jointly with Stracon, own business, and business owned by Stracon conducted with third parties. This strategy is intended to generate synergies, economies of scale and tax efficiencies from the integration of the mining-related businesses and taking advantage of the individual experience of both entities now conducting this restructured business.

The structure of this transaction consisted of transactions made by both entities to obtain a certain percentage of interest in Stracon—GyM, and an additional contribution of GyM. As a result of the several contributions that each party engages to make , the share capital structure of Stracon—GyM was attributed to shareholders as follows: 74.15% to GyM and 25.85% to Stracon. GyM has control over the overall operation and it applies IFRS 3 to account for this transaction.

c) Acquisition of Compañía América de Multiservicios Limitada - CAM -

On January 19, 2011, CAM Holding SPA and Inversiones y Construcción GyM Limitada, two subsidiaries created by the Group to carry out this transaction, signed an agreement of “Assignment of Capital Stock” with Enersis S.A. and Chilectra S.A. (the “selling parties”) under which they transfered their respective holdings of 99.958802% and 0.041197%, respectively, in the capital stock of Compañía América de Multiservicios Limitada—CAM (hereinafter CAM). As consideration, Group subsidiaries paid the sellers an initial price of US$20.2 million, subject to adjustments based on several variables, such as changes in equity of CAM between the date the price was set and the date the transaction was executed.

CAM is en entity based in Chile and formed in 1998 with three business units: energy consumption measurement, implementation of electric power work and logistical services, that are provided directly or through subsidiaries operating in 5 countries in South America (Chile, Argentina, Brazil, Peru and Colombia).

On February 24, 2011, the CAM purchase transaction was closed. Immediately following the closing, the Company sold to a partner 25% of the capital stock of CAM under the same terms and conditions under which it was acquired. Such partner paid US$5.0 million for the 25% interest. The final purchase price paid by the Group was reduced by both the effect of the incoming partner, as well as certain seller adjustments to the final purchase price. Taking into account these adjustments, the price paid by the Group for the 75% interest in CAM’s capital stock amounted to US$10.8 million.

This purchase has been performed as part of the Group’s strategy to position its investments in Chile, and enter into profitable business segments which generate an increase in the operations of the Group.

The Group distributed the price paid based on the fair values of the assets acquired and liabilities assumed on February 24, 2011, the date of acquisition. A breakdown of this calculation is shown as follows:

	S/.000			US$000

(All amounts are expressed in thousands of S/. unless otherwise stated)

(*) Non-controlling interest was determined as the proportion of assets acquired and liabilities assumed from CAM.

This acquisition has generated a gain of S/.45.2 million which resulted in, as established by IFRS 3, a review of the values initially attributed to assets and liabilities of the acquired entity. As of the date of the financial statements, the Group completed this review and in accordance with Note 4.2, concluded its distribution process of the amount paid for the purchase and accordingly, it recognized this gain in the income statement under “Business combination gain”.

The contribution of CAM to the income and profit of the Group from February 24 to December 31, 2011 amounts to S/.466.7 million and S/.29.4 million, respectively. If CAM had been consolidated with effect from January 1, 2011, income and profit would have been S/.558.2 million and S/.21 million, respectively.

30 EARNINGS PER SHARE

Basic earnings per share are calculated by dividing the net profit of the period attributable to common shareholders of the Group by the weighted average number of common shares in issue during the year. No diluted earnings per common share were calculated because there are no common or investment shares with potential dilutive effects (i.e., financial instruments or agreements that give the right to obtain common or investments shares); therefore, it is equal to basic earnings per share. The basic earnings per share are broken down as follows:

	2011		2012
	S/.000		S/.000
Profit attributable to the controlling interest in the Company		289,076		289,954

32 RESTATEMENT

The Company has restated its consolidated statement of cash flows for the year ended December 31, 2012 to correct two errors. These errors had no effect on the net increase (decrease) in cash of the Company during 2012 and no effect on the Company’s statement of financial position, income statement, statement of comprehensive income or statement of changes in shareholders’ equity for 2012.

The first correction is to appropriately reflect the cash flow impact of the Stracon GyM acquisition transaction completed in March 2012. See note 28b. This transaction was consummated primarily through GyM’s and Stracon’s contribution of assets and liabilities to Stracon GyM, and therefore was substantially a non-cash transaction. The assets and liabilities contributed by the Company to Stracon GyM had been held on the Company’s books prior to this transaction. As a result, the contribution of these assets and liabilities should not have produced an effect on the statement of cash flow as they had no effect on cash and were not part of the changes in balance sheet accounts from one period to another. However, the Company erroneously reflected those assets and liabilities in the statement of cash flow by making eliminations to certain amounts of the cash flow statement, as if the assets and liabilities represented new assets and liabilities acquired during the period. Because these assets and liabilities existed prior to this transaction, there was no need to eliminate these non-cash amounts in the mechanical calculation of the determination of the cash effect of changes in assets and liabilities during the period.

The effect of correcting this error was an increase in net cash flows provided by operating activities of S./103,427, an increase in net cash applied to investing activities of S./95,675 and a decrease of net cash applied to financing activities of S./ 7,752. There was no effect on the net increase (decrease) in cash for 2012.

The second correction is to appropriately reflect in the statement of cash flows the impact of entering into new finance leases during 2012. See note 16b. Finance leases entered into by the Company are non-cash transactions.

In order to reflect finance leases as non-cash transactions, these transactions must be eliminated in the preparation of the statement of cash flows. In the process of accounting for the finance leases entered into during 2012, the Company erroneously applied an incorrect elimination amount to the statement of cash flows.

This error resulted in a misstatement of net cash provided by (applied to) investing activities and net cash provided by (applied to) financing activities. The effect of correcting this error was an increase in net cash applied to investing activities of S./102, 059 and a decrease of net cash applied to financing activities of S./102,059. There was no effect on the net increase (decrease) in cash for 2012.

These two errors also impact the statement of cash flow segment disclosures in note 5. The Engineering and Construction segment cash flow statement for the year ended December 31, 2012 has also been restated to reflect the above described corrections.

In the aggregate, the two errors had no effect on the net increase (decrease) in cash of the Company during 2012. In addition, all underlying transactions were properly recorded in the statement of financial position, income statement, statement of comprehensive income and statement of changes in shareholders’ equity for 2012.

Supplementary Data (Unaudited)

Oil and Gas Producing Activities

In accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 932, “Extractive Activities—Oil and Gas,” and regulations of the U.S. Securities and Exchange Commission (SEC), the Company has included certain supplemental disclosures about its oil and gas exploration and production operations.

A. Reserve Quantity Information

Graña y Montero Petrolera S.A. net proved reserves in the fields in which they operate and changes in those reserves for operations are disclosed below. The net proved reserves represent best estimate of proved oil and natural gas reserves. For, 2012 reserve estimates have been evaluated by independent qualified reserves consultants, Netherland, Sewell & Associates, Inc. (NSAI). For 2011 and 2010 the reserve estimates were prepared by internal engineers. The estimates for all years presented conform to the definitions found in FASB ASC paragraph 932-10-65-1 and Rule 4-10(a) of Regulation S-X.

Proved oil reserves are those quantities of oil, which, by analysis of geosciences and engineering data, can be estimated with reasonable certainty to be economically producible, based on prices used to estimate reserves, from a given date forward from known reservoirs, and under existing economic conditions, operating methods, and government regulation prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain.

The term “reasonable certainty” implies a high degree of confidence that the quantities of oil actually recovered will equal or exceed the estimate. To achieve reasonable certainty, the Company’s engineers and independent petroleum consultants relied on technologies that have been demonstrated to yield results with consistency and repeatability. The technologies and economic data used to estimate the Company’s proved reserves include, but are not limited to, well logs, geologic maps, seismic data, well test data, production data, historical price and cost information and property ownership interests.

F-91

(1) Proved reserves estimated in oil and gas properties located in Block I and V (Talara) under two service contracts with Petroperu S.A. The rights to produce hydrocarbons expire in December 2021 for Block I and October 2023 for Block V. The proved reserves estimated in this report constitute all of the proved reserves under contracts by Graña y Montero Petrolera S.A.

(2) The revisions in reserves estimates are based on new information obtained as a result of drilling activities and workovers. The principal factors affecting the revisions to the reserves estimates are changes in the historical relation between crude oil and natural gas found in our productive wells as well as changes in our drilling activities program and workovers, based on geological and engineering studies undertaken. In 2010 and 2011, the decreases in crude oil estimates were principally due to changes in well production. In 2012, the decrease in crude oil reserves estimates was principally due to changes in the drilling activities program based on geological and engineering studies, which changes consisted of the elimination of four drilling locations in Block V, partially offset by six new drilling locations in Block I. During 2010, 2011 and 2012, natural gas reserves estimates increased as a result of the higher natural gas/crude oil relationship in the wells drilled over the last years.

E. Standardized Measure of Discounted Future Net Cash Flows

The standardized measure of discounted future net cash flows, related to the proved reserves is based on estimates of net proved reserves and the period during which they are expected to be produced. Future cash inflows are computed by applying the twelve month period unweighted arithmetic average of the price as of the first day of each month within that twelve month period, unless prices are defined by contractual arrangements, after royalty share of estimated annual future production from proved oil and gas reserves.

Future production and development costs to be incurred in producing and further developing the proved reserves are based on year end cost indicators. Future income taxes are computed by applying year end statutory tax rates.

	Total
	2010			2011			2012
	(in US$ thousands)
Future Cash inflows(1)		330,772			432,181			375,655
Future production costs(2)		(83,249	)		(75,402	)		(94,793	)

Future production and development costs		(123,263	)		(111,317	)		(138,455	)
Future income tax expenses(4)		(62,253	)		(96,259	)		(71,160	)
Future Net cash flows(5)		145,256			224,605			166,040
10% annual discount for estimates timing of cash flows		(54,024	)		(79,001	)		(49,887	)
Standardized measure of discounted Future Net Cash Flows		91,232			145,604			116,152

(1) For oil volumes, per barrel prices after deductions of Graña y Montero Petrolera S.A.’s share government royalties used in determining future cash inflows for the years ended December 31, 2010, 2011 and 2012 were US$ 62.00, US$ 86.29 and US$ 87.25, respectively. For gas volumes, gas price is linked to the oil price according to the gas purchase contract (US$ 1.29 per MCF are held constant throughout the lives of the properties).

F-94

(2) Production costs and developments costs relating to future production of proved reserves are based on the continuation of existing economic conditions. Future decommissioning costs are included.

(3) During 2010 and 2011, the Company did not have future development costs associated with the abandonments of wells. During 2012, the Company estimated future development costs associated with the abandonment of wells in an amount equal to approximately US$2.1 million. See note 19.

(4) Taxation is computed using the appropriate year-end statutory corporate income tax rates.

(5) Future net cash flows from oil production are discounted at 10% regardless of assessment of the risk associated with its producing activities.

GRAÑA Y MONTERO S.A.A. AND SUBSIDIARIES

NOTES TO THE CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

MARCH 31, 2012 (UNAUDITED) AND 2013

1 GENERAL INFORMATION

The Company is the parent company of the Graña y Montero Group (hereinafter the Group) and its principal activity is the holding of investments in the different companies of the Group. Additionally, the Company provides services of general management, financial management, commercial management, legal advisory and human resources management to Group companies; it is also engaged in the leasing of offices to Group companies and third parties.

The Group is a conglomerate of companies with operations including different business activities, of which the most significant are engineering and construction, infrastructure (public concession operation), real estate businesses and technology services.

These condensed interim consolidated financial statements as of March 31, 2013 have been prepared and authorized for issuance by the Chief Financial Officer on June 3, 2013.

2 BASIS OF PREPARATION

These condensed interim consolidated financial statements for the three-month period ended March 31, 2013 have been prepared in accordance with (IAS 34) “Interim financial reporting”. The condensed interim consolidated financial statements should be read in conjunction with the annual consolidated financial statements for the year ended December 31, 2012, which have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

3 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting policies used in the preparation of these interim condensed consolidated financial statements are consistent with those applied in the preparation of the year-end financial statements at December 31, 2012, except for income taxes, which for the interim period have been recognized applying the tax rate that would be applicable for 2013.

IFRS and amendments to IFRS applicable for the first time for the period covered in these interim financial statements. -

New IFRS or amendments to IFRS mandatory from January 1, 2013 have been considered by the Group in the preparation of these interim consolidated financial statements; however, they have not resulted in changes in the prior-year accounting policies. Major new IFRS or amendments to IFRS relevant to the Group activities are as follows:

• IFRS 7, ‘Financial instruments: Disclosures’ as amended in October 2010. The IASB modified the disclosures required so that the users of the financial statements may assess the risk exposure related to financial asset transfers and the effect of these risk on the entity’s financial position. This standard did not result in significant changes in the disclosures in the interim consolidated financial statements.

• IFRS 10, “Consolidated financial statements”—The application of this standard has not resulted in changes in the consolidation criteria applied by the Group.

• IFRS 11, “Joint arrangements”—The application of this standard has not resulted in changes in the criteria applied by the Group in the recognition of interests in joint arrangements. Until 2012, the Group’s interest in these types of arrangements, mostly joint operations, were recognized as joint

F-102

(All the amounts are expressed in thousands of S/. unless otherwise stated)

operations within the scope of IAS 31. As a result of the assessment of the assets and obligations for the liabilities arising from contracts, the Group has arrived at the conclusion that its interest in those contracts continue to be classified as joint operations. Therefore, the Group recognizes in its financial statements its share in the assets, liabilities, revenues and expenses of this type of contracts.

• IFRS 12, “Disclosures of interests in other entities”. This standard did not result in significant changes in the disclosures in interim consolidated financial statements.

• IFRS 13, ‘Fair value measurement’, aims to improve consistency and reduce complexity by providing a precise definition of fair value and a single source of fair value measurement and disclosure requirements for use across IFRSs. The requirements do not extend the use of fair value accounting but provide guidance on how it should be applied where its use is already required or permitted by other standards within IFRSs. See changes in disclosures in interim consolidated financial statements in note 4.3.

• Amendment to IAS 1, ‘Presentation of financial statements’ relating to other comprehensive income. The major change resulting from this amendment is the requirement for entities to group the items of “other comprehensive income” (OCI) depending on whether they are reclassifiable or not to the statement of comprehensive income. See changes on disclosures in OCI.

• IAS 19, ‘Employee benefits’ was amended in June 2011 by the IASB. The amendments eliminate the corridor approach and recognize financial expenses on a net basis. The adoption of this standard did not result in significant changes in the disclosures in interim consolidated financial statements nor have a material impact on the Group’s financial position or performance.

• IAS 28, ‘Investments in Associates and Joint Ventures’. It was amended in May 2011 by the IASB. The new standard includes guidelines to recognize joint ventures and associates under the equity method. The adoption of this standard did not result in significant changes in the disclosures in interim consolidated financial statements nor have a material impact on the Group’s financial position or performance.

4 FINANCIAL RISK MANAGEMENT

4.1 Financial risk factors

The Group’s activities expose it to a variety of financial risks: market risk (including currency risk, price risk, fair value interest rate risk and cash flow interest rate risk), credit risk and liquidity risk.

The condensed interim consolidated financial statements do not include all financial risk management information and disclosures required in the annual financial statements; these should be read in conjunction with the Group’s annual financial statements as of December 31, 2012. There have been no changes since year-end in the risk management department of the Group or in any risk management policies.

4.1.1 Market risk

Compared to year end, no new material market risk hedging arrangements have occurred.

4.1.2 Credit risk

Compared to year end, the Group has no exposure to any new relevant credit risk.

4.1.3 Liquidity risk

Compared to year end, no major changes in undiscounted contractual cash flows have occurred, except for changes in the structure of the Group’s liabilities, resulting from an increase in the long-term debt relating to a syndicated loan which matures in 2018 (Note 11); the proceeds of this debt were used to repay a short-term loan and to finance investment activities of subsidiary GyM Ferrovías.

F-103

(All the amounts are expressed in thousands of S/. unless otherwise stated)

The following table categorizes the Group’s financial liabilities into relevant maturity groupings based on the remaining period from the date of the statement of financial position to the contractual maturity date. The amounts disclosed in the table are the contractual undiscounted cash flows:

	Less than 1 year		From 1 to 2 years		From 2 to 5 years		Over 5 years		Total
	S/.000		S/.000		S/.000		S/.000		S/.000

		1,616,380		147,504		398,879		98,361		2,261,124

(*) Includes interest.

4.2 Capital management

The Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is calculated as total borrowings (including current and non-current borrowings), less cash and cash equivalents. Total capital is calculated as total ‘equity’ as shown in the consolidated statement of financial position plus net debt.

As of March 31, 2013 and at December 31, 2012 the gearing ratio was as follows:

	At December 31, 2012			At March 31, 2013
	S/.000			S/.000
Total borrowings		845,474			925,429
Less: Cash and cash equivalents		(780,114	)		(653,040	)
Net debt		65,360			272,389
Total equity		1,776,890			1,788,720
Total capital		1,842,250			2,061,109
Gearing ratio		0.04			0.13

The gearing ratio is maintained within the limits set by Group Management, between 0.04 and 1.00. The increase in this ratio resulted from a slight increase in debt ratios and a decrease in cash and cash equivalent balances that were used in investments within the Group.

4.3 Fair value estimation

For the classification of the type of valuation used by the Group for its financial instruments at fair value, the following levels of measurement have been established:

• Level 1: Measurement based on quoted prices in active markets for identical assets or liabilities.

• Level 2: Measurement based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability (level 1), either directly (that is, as prices) or indirectly (that is, derived from prices).

Level 3: Measurement based on inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs, generally based on internal estimates and assumptions of the Group).

The only financial instruments measured at fair value by the Group are interest rate swaps (variable to fixed), forward foreign exchange contracts (mostly euros and U.S. dollars) and available-for-sale investments. The measurement at fair value of these instruments corresponds to the characteristics of Level 2 and has been determined based on the present value of discounted future cash flows. During the three-month period ended March 31, 2013 there were no changes in the levels of measurement of financial instruments at fair value.

The carrying amount of cash and cash equivalents corresponds to its fair value. The Group considers that the carrying amount of short-term accounts receivable and payable approximates fair value. The fair value of financial liabilities has been estimated by discounting the future contractual cash flows at the interest rate currently prevailing in the market and which is available to the Group for similar financial instruments.

Fair value hierarchy -

The following table presents the Group’s financial assets and liabilities that are measured at fair value as of March 31, 2013.

	Level 1		Level 2		Level 3		Total
	S/.000		S/.000		S/.000		S/.000
Assets:
Derivative financial instruments		—		35		—		35
Total assets		—		35		—		35

	Level 1		Level 2		Level 3		Total
	S/.000		S/.000		S/.000		S/.000
Liabilities:
Derivative financial instruments—Cashflow hedging		—		16,702		—		16,702
Total liabilities		—		16,702		—		16,702

There were no transfers between Levels 1, 2 and 3 during the period.

Valuation techniques used to derive Level 2 fair values -

Level 2 hedging derivatives comprise forward foreign exchange contracts and interest rate swaps. These forward foreign exchange contracts have been fair valued using forward exchange rates that are quoted in an active market. Interest rate swaps are fair valued using forward interest rates extracted from observable yield curves. The effects of discounting are generally insignificant for Level 2 derivatives.

F-105

(All the amounts are expressed in thousands of S/. unless otherwise stated)

Group’s valuation processes -

The Corporate General Manager reviews the fair value of derivatives instruments by using the information provided by local financial institutions. Management performs this review at each reporting date. This information is reviewed at first by subsdiriaries’ management, and subsequently by the Corporate General Manager.

The Group has its financial instruments only in Level 2.

5 CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS

The preparation of the condensed interim consolidated financial statements requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, income and expense. Actual results may differ from these estimates.

In preparing these condensed interim consolidated financial statements, the significant judgements made by management in applying the Group’s accounting policies and the key sources of uncertainty were the same as those that applied to the consolidated financial statements for the year ended December 31, 2012, with the exception of changes in estimates that are required in determining the provision for income taxes for this interim period.

6 SEASONALITY OF OPERATIONS

The Group shows no material seasonality in the operations of any of its subsidiaries; operations are carried out regularly during the course of the year.

7 SEGMENT REPORTING

Operating segments are reported consistent with the internal reports that are reviewed by the Corporate General Manager, who is the chief operating decision maker, responsible for allocating resources and evaluating the performance of each operating segment.

The Group’s operating segments are assessed by the activity of the following business units: (i) engineering and construction, (ii) infrastructure, (iii) real estate, (iv) technical services and (v) the operation of the Parent Company (Holding).

As set forth under IFRS 8, reportable segments by significance of income are: ‘engineering and construction’ and ‘technical services’. However, the Group has voluntarily decided to report on all its operating segments as detailed in this Note.

Inter-segmental sales transactions are entered into at prices that are similar to those that would have been agreed to with unrelated third parties. Revenues from external customers reported to the Corporate General Manager are measured in a manner consistent with the basis of preparation of the financial statements.

Group sales and receivables are not concentrated on a few customers.

Item 9. Undertakings

The undersigned registrant hereby undertakes:

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 6 of this Registration Statement, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted against the Registrant by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

1. For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement at the time it was declared effective.

2. For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

For the purposes of Item 512(F) of Regulation S-K, the Registrant hereby also undertakes to provide to the underwriters at the closing specified in the underwriting agreement, certificates in such denominations registered in such names as required by the underwriters to permit prompt delivery to each purchaser.
