Grana y Montero Consolidated Results Report – Third Quarter 2016 Consolidated Results Revenues Consolidated revenues reached S/. 4,238.3 MM during 3Q2016, a decrease of 24.6% compared to 3Q2015. In terms of Business Segments, revenues in the Engineering and Construction segment decreased 36.0% in 3Q2016, contributing with 60.0% of the Group’s revenues. The Infrastructure Segment decreased 10.9% due mainly to lower revenues in GMP and Survial; while the Real Estate Area registered an increased of 84.9% mainly explained by the sale of a piece of land from Almonte. Finally, the Technical Services Segment registered an increase of 17.6% which includes the consolidation of Adexus since August. Gross Profit Consolidated Gross Profit decrease from S/.467.7 MM to S/. 450.1 MM, equivalent to a decrease of 3.8% and a Gross Margin of 10.6% in 3Q2016, which is higher to the gross margin of 3Q2015. This is mainly explained by the improved results in the Real Estate Business Area, and more stable margins in the Engineering and Construction Area. In the Infrastructure Area, the Gross Profit increased from 18.6% to 19.8%. Operating Income In the “Other Operational Expenses” line of 3Q2016, reflects the profit from the sale of machinery and equipment, as well as a price adjustment in the purchase of Morelco, a reverse of provisions, and the extraordinary income from an agreement reached in the Collahuasi Project in Chile. In the “Profit from sale of investments in subsidiaries” line, the profit from the sale of our stake in the Transportadora de gas del Peru (Tgp) is registered, which also has an impact in the income tax due to the reversal of the deferred Income Tax. The increase in Financial expenses is a consequence of the increase in the debt of the Gaseoducto del Sur contribution financing. The “Participation in Associates” account registers the profit generated in projects where subsidiaries have a minority stake and are not consolidated. This number includes mainly the Southern Gas Pipeline stake and the Guyana Prokect, as well as other minority investments such as COGA, Chavimochic and Adexus. Exchange rate difference During the year, the Sol has maintained relatively stable resulting in an exchange rate difference of S/. 4.1 MM.
