These interim financial statements are prepared in accordance with International Accounting Standard (“IAS”) 34, Interim Financial Reporting, pursuant to the provisions in Technical Resolution No. 26 (as amended) issued by the Argentine Federation of Professional Councils of Economic Sciences [FACPCE] and the Regulations issued by the Argentine Securities Commission [“Comisión Nacional de Valores” (CNV)].

Consequently, not all of the disclosures required in accordance with International Financial Reporting Standards (IFRS) for annual financial statements are included herein, hence, these interim financial statements shall be read in conjunction with the Company’s consolidated financial statements for the fiscal years ended December 31, 2018 and 2017 issued on March 7, 2019.

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(All amounts are stated in Argentine Pesos - $ - unless otherwise stated)

The Group has not opted for early adoption of any other standard, interpretation or amendment that has been issued but is not yet in force.

● New standards

New standards and interpretations issued during the three months period ended March 31, 2019 and the standards and interpretations issued but not mandatory as of that date are described in Note 2.2 to the consolidated financial statements as of December 31, 2018. Note 16 contains a description of the impact of the application of IFRS 16 to these consolidated condensed interim financial statements.

2.3.2 Ferrocarril Roca Management Trust

The interest in the Ferrocarril Roca Management Trust is valued at cost value, taking into account the value of contributions made, net of trust expenses, plus the financial income/(loss) accrued until the closing of the fiscal year/period. The following unconsolidated information is for the entity not controlled by Ferrosur Roca S.A.

As of March 31, 2019 and December 31, 2018, Ferrosur Roca S.A. owns 100% of the following (unconsolidated) assets and liabilities:

	03.31.2019	12.31.2018
Current assets	77,074,368	62,581,344
Current liabilities	73,810	82,503
Shareholders’ equity	77,000,558	62,498,841

3.CRITICAL ACCOUNTING OPINIONS AND KEY SOURCES USED FOR ESTIMATING UNCERTAINTY

When applying the Group's accounting policies, the directors of the Company are required to make assessments, estimates and assumptions regarding the carrying amounts of assets and liabilities. The estimates and related assumptions are based on past experience and other factors that are considered relevant. Actual results may differ from these estimates.

The unaudited condensed interim consolidated financial statements reflect all adjustments which are, in the opinion of Management, necessary to make a fair statement of the results for the interim periods presented.

There are no significant changes to the critical judgements used by Management in applying accounting policies to the critical judgements disclosed in the annual consolidated financial statements for the year ended December 31, 2018.

As a consequence of the activities in which the Company is engaged, the transactions of the Company do not have a significant cyclical or seasonal character. Nevertheless, during the second half of the year, historically the volume of sales in Argentina has showed a slight increase.

8.TAX ON BANK DEBITS AND CREDITS

The general tax rate for bank debits and credits is 0.6% for amounts credited or debited to or from the Company's bank accounts. For credited and debited amounts, 33% of both items may be used as payment of account of other taxes. 67% on credits and debits is included in this line of the comprehensive income statement.

Under Argentine Law No. 27,432, the Argentine Executive may provide that the percentage of the aforesaid tax that is not computable as payment on account of income tax be progressively reduced by up to an annual twenty percent (20%) as from January 1, 2018, with an option to establish that, in 2022, the tax provided for under Argentine Law No. 25,413, as amended, be fully considered as payment on account of income tax. On May 7, 2018 Decree 409/2018 published in the Official Gazette established that taxpayers subject to the general rate of twelve per thousand may use the 33% on debits and credits to the related bank accounts on account of income tax payable.

Exchange difference losses are mainly due to the net changes in the valuation of assets and liabilities denominated in US Dollars as a consequence of a devaluation of the Argentine Peso against the US Dollar in the three months period ended March 31, 2019, compared with such variation of the exchange rate during the same period in 2018.

10.INCOME TAX

Income tax expense is recognized on the basis of the actual expenses and the statutory rate expected at year-end.

This criterion does not significantly differ from the criterion established in IAS 34, which requires income tax expense to be recognized in each interim period based on the best estimate of the effective tax rate expected as of year-end.

The reconciliation of income tax expense for the three months periods ended March 31, 2019 and 2018 and that which would result from applying the statutory rate in force on the net income before income tax for the condensed interim comprehensive income statement for each period is as follows:

	03.31.2019		03.31.2018
Income/(loss) before income tax	1,271,052,117		947,236,298

16.RIGHT TO USE ASSETS AND LIABILITIES FOR LEASES

On January 13, 2016, the International Accounting Standards Board (IASB) published IFRS 16, a new standard on leases to replace IAS 17, IFRIC 4, SIC-15 and SIC-27, effective for fiscal years beginning on or after January 1, 2019.

20

LOMA NEGRA COMPAÑÍA INDUSTRIAL ARGENTINA SOCIEDAD ANÓNIMA

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(All amounts are stated in Argentine Pesos - $ - unless otherwise stated)

Said IFRS introduces that most lease agreements (and sub-lease agreements) are recognized in the accounting of the lease under a single model eliminating the distinction between operating and financial leases, and requires recognizing an asset for the right to use the leased asset and a liability reflecting the obligation to make future payments for the lease. There are no significant changes for the accounting of the lessor in relation to IAS 17.

The Company applied IFRS 16 using the modified retrospective method pursuant to paragraphs C5(b) and C8(b)(ii) as of the date of initial application. Under this method, IFRS 16 is retroactively adopted with the accumulated effect of the initial application recognized as of the date of initial application and the comparative information is not restated.

The Company has executed lease agreements, mainly for offices and land.

As from the application of IFRS 16, the Company has adopted an accounting method for recognition and measurement of all leases.

For leases previously classified as operating leases, the Company has recognized assets for the right to use and liabilities for leases, except for agreements for a term of less than twelve months (short term leases), for those associated to the exploitation of natural resources and for those where the underlying asset has low value. Assets and liabilities are initially measured on the basis of current value. Assets for the right to use have been recognized for an amount equivalent to liabilities for leases. Lease liabilities have been measured at current value of lease payments not paid yet, using the incremental rate for loans of the Company (the lessee) to the date of initial application.

Summary of the new accounting policies

Assets for right to use

The Company recognizes an asset for the right to use at the beginning of each lease (date when the asset is available for use). The assets for the right to use is measured at cost, net of accumulated depreciation and impairments, and adjusted for any remeasurement of liabilities and to recognize changes in the purchasing power of the currency. The cost of assets for the right to use includes the amount of liabilities for lease recognized, initial direct costs incurred and payments made before the date of commencement of the lease, minus any incentives received. Unless the Company is certain that it will acquire the asset at the end of the lease, assets for the right to use are depreciated in a lineal manner throughout the term of the estimated useful life and the period of the lease, whichever is shorter. Assets for the right to use are subject to impairment.

Lease payables

Liabilities for leases are measured at current value of future lease payments to be made throughout the lease period. Lease payments include fixed payments minus any incentives to be received, variable payments depending on an index or rate and values expected to be paid as security of residual value. Payments also include the value of the exercise of any option to purchase the underlying asset leased and any penalties for termination of the lease, provided it is reasonably possible that the Company will exercise such options. Variable payments not depending on an index or rate are recognized in the results of the period when the condition they are subject to takes place.

Significant judgments to determine the lease period

The Company determines the periods of leases as the period during which the lease cannot be cancelled, together with any period covered by an option to extend or terminate the lease, provided the Company is reasonably certain that it will exercise such option.

The Company applies judgment in determining whether it will renew its leases, taking into consideration all relevant factors creating an economic incentive for the Company to exercise such options.

Amounts recognized in the financial statements

The effects of the application of IFRS 16 as of January 1, 2019 (date of initial application) and as of March 31, 2019 are as follows:

26.3 Financial risks

The Group´s activities are exposed to a variety of financial risks: market risk (including foreign currency risk, interest rate risk and price risk considering the current inflation rates), credit risk and liquidity risk. The Group maintains an organizational structure and systems that allow the identification, measurement and control of the risks to which it is exposed.

These condensed interim consolidated financial statements do not include all the information and disclosures on financial risks, therefore, they should be read in conjunction with the Company´s consolidated financial statements for the fiscal years ended December 31, 2018 and 2017 issued on March 7, 2019.

26.4 Fair value measurement

Fair value measurement is described in Note 32.9 to the annual consolidated financial statements.

From December 31, 2018 through March 31, 2019, there have been no significant changes in the industry’s economic activity affecting the fair value of the Group´s financial assets and liabilities, either measured at fair value or amortized cost. In addition, there were no transfers among the different levels of fair value hierarchy to assess the fair value of the Company's financial instruments during the three months period ended March 31, 2019.

The carrying amounts of financial assets and liabilities recognized at amortized cost, included in the consolidated financial statements as of March 31, 2019 and December 31, 2018, approximate to their fair values. Borrowings are measured at amortized cost considering the effective interest rate method, which approximate to their fair value given their cancellation period.

NOTES TO THE UNAUDITED CONDENSED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

(All amounts are stated in Argentine Pesos - $ - unless otherwise stated)

The Management of the Company considers that the liquidity risk exposure is low since the Company has been generating cash flows from its operating activities, supported on strong profits, and has access to loans and financial resources, as explained in Note 21.

26.5 Exchange risk management

The Group carries out transactions in foreign currency and is hence exposed to exchange rate fluctuations. Exposures in the exchange rate are managed within approved policy parameters using foreign exchange contracts.

The carrying amounts of monetary assets and liabilities stated in foreign currency at the end of the reporting period/year are as follows:

	03.31.2019	12.31.2018
Liabilities
United States Dollars	4,655,009,643	4,266,842,181
Guaraníes	2,790,070,151	3,148,674,560

Foreign currency sensitivity analysis

The Group is mainly exposed to the US Dollar.

The following table shows the sensitivity of the Group to an increase in the US Dollar and Guaraní exchange rates. The sensitivity rate is the one used when the exchange risk is reported internally to key management personnel and represents the management's assessment of a possible reasonable change in exchange rates. The sensitivity analysis only includes outstanding foreign-currency monetary items and adjusts its conversion as of the end of the period/year considering a 25% increase in the exchange rate considering all the items of controlled companies in the calculation.

	Effect of US Dollars	Effect of the Guaraní
	03.31.2019	03.31.2019

28.OPERATING SEGMENTS

The Company has adopted IFRS 8 - Operating Segments, which requires operating segments to be identified on the basis of internal reports regarding components of the Company that are regularly reviewed by the Executive Committee, the chief operating decision maker, in order to allocate resources and evaluate their performance. Said analysis is based on monthly information on historical figures of the segments identified.

7. FUTURE PROSPECTS

Forecasts for the Argentine economy indicate a decrease in the GDP for 2019 in relation to 2018. For the second semester, a change in the trend is expected with regularization of the main economic variables, and the historically positive factor of election years, which will be reflected in the construction industry in general and the cement industry in particular.

Taking into consideration the current scenario and future prospects, the Company is currently working on readapting its production costs and structure expenses to the expected production levels, for the purposes of maintaining the levels of profitability in the current context of the business.
