CONSOLIDATED RESULTS OF OPERATIONS2Q15 versus 2Q14

Sales volume increased 4% to 960 thousand metric tons, the majority of which was generated by Gruma Corporation. Net sales rose 16% to Ps.14,280 million, driven principally by (1) the peso depreciation effect, which benefitted sales from the U.S. operations when stated in peso terms; and (2) the aforementioned sales volume growth. Cost of sales as a percentage of net sales improved to 62.0% from 63.5%, reflecting better performance mostly at Gruma Corporation and, to a lesser extent, at Other Subsidiaries and Eliminations. Also, Gruma Centroamerica reported improvements. In absolute terms, cost of sales increased 13% to Ps.8,855 million due to the effect of the peso depreciation and the aforementioned sales volume growth. Selling, general and administrative expenses (SG&A) as a percentage of net sales increased to 25.1% from 24.2% due mainly to a higher proportion of Gruma Corporation in the consolidated figures as well as higher expenses at GIMSA. In absolute terms, SG&A rose 20% to Ps.3,584 million mainly in relation to the effect of the peso depreciation and, to a lesser extent, higher selling expenses. Operating income grew 22% to Ps.1,840 million, driven primarily by Gruma Corporation and, to a lesser extent, the positive effect of the peso depreciation. Operating margin rose to 12.9% from 12.3% led primarily by Gruma Corporation. EBITDA increased 21% to Ps.2,242 million. EBITDA margin expanded to 15.7% from 15.1%. Net comprehensive financing cost was Ps.59 million, Ps.133 million less due to lower financial expenses, primarily driven by lower debt, and gains on foreign exchange derivatives related to corn purchasing at GIMSA. Income taxes were Ps.558 million, Ps.339 million more reflecting higher pre-tax income and one-time benefits accrued in 2014 related to changes in Mexico's fiscal law. The effective tax rate was 31.3%. Discontinued operations resulted in a loss of Ps.67 million, mostly in connection with exchange-rate adjustments to accounts receivable related to the Venezuelan operations. The discontinued operations line had an unfavorable comparison of Ps.171 million, as 2Q14 figures included the results of GRUMA's former wheat flour operations, which were sold in December 2014. Majority net income decreased 5% to Ps.1,081 million, as better operating performance and lower net comprehensive financing cost were offset by higher taxes and losses from discontinued operations.

FINANCIAL POSITIONJune 2015 versus March 2015

Balance Sheet Highlights Total assets were Ps.44,601 million, a rise of 7% reflecting increases in: cash balances, inventories, in connection with the summer corn crop in Mexico, and property, plant, and equipment, resulting from the company's expanded capital expenditures program during 2015. Total liabilities were Ps.24,773 million, 9% more, mainly as a result of (1) higher other accounts payable resulting from dividends that GRUMA paid on July 8, 2015; and (2) higher trade accounts payable related to the summer corn crop in Mexico. Shareholders' equity totaled Ps.19,828 million, 5% more than at March 2015.

Debt Profile GRUMA's debt totaled US$736 million, US$22 million less than at March 2015. Approximately 96% of GRUMA's debt is dollar-denominated.

CAPITAL EXPENDITURE PROGRAM GRUMA's capital expenditures totaled US$33 million during 2Q15, and were allocated mostly to (1) technology upgrades at Gruma Corporation and GIMSA; (2) capacity expansions at several tortilla plants in the U.S. and at the corn flour plant in Mexicali (northwest Mexico); and (3) the construction of a tostada plant in Tijuana (northwest Mexico) and a tortilla plant in Russia.

SUBSIDIARY RESULTS OF OPERATIONS2Q15 versus 2Q14

Gruma Corporation Sales volume rose 7% to 444 thousand metric tons. The volume increase was driven by both the U.S. and European operations. In the U.S., corn flour grew as a result of (1) gaining share through the better quality of our corn flour in comparison to other brands; (2) increased consumption in restaurants; and (3) better executed retail promotions at several supermarket chains. The U.S. tortilla operations rose due to (1) the retail segment, resulting from increased penetration, shelf space gains, product assortment optimization, new private-label supply agreements at the expense of competitors, and the increasing popularity of some of our tortillas, whose improved quality continues to be well accepted by consumers; and (2) the foodservice segment, resulting from organic growth and the expansion of some fast-food restaurant chains, the introduction and promotion of menu items made with tortillas by several restaurant chains, and additional business among foodservice distributors. The European operations grew in connection with higher sales of grits and corn and with the recent acquisition in Spain. Net sales grew 4% to Ps.8,980 million. Net sales rose at a lower rate than sales volume principally because of the devaluation of the euro. Cost of sales as a percentage of net sales improved to 60.6% from 61.9% driven by the U.S. tortilla operations as a result of (1) better fixed cost absorption in connection with volume growth; (2) lower raw material costs while prices were relatively stable; (3) lower allowances related to ongoing efforts to better manage allowance trade spending; (4) better sales mix by focusing on high-margin products, presentations and brands; and (5) efficiencies in fixed overhead and warehousing costs. Also, cost of sales as a percentage of net sales improved because of the change in the sales mix towards the U.S. tortilla business, which has better gross margins than the rest of the operations. In absolute terms, cost of sales increased 2% to Ps.5,442 million related to the aforementioned sales volume growth. SG&A as a percentage of net sales improved to 28.2% from 28.7% driven by the U.S. operations as a result of better absorption related to volume growth. In absolute terms, SG&A rose 3% to Ps.2,531 million, in connection with (1) sales volume growth and better sales mix resulting in higher sales commissions, especially at the U.S. tortilla business; (2) the launch of the Mission brand in several countries within Europe; (3) strengthening of the sales team and administrative areas in Europe to support growth at the tortilla and flatbread businesses; and (4) the recent acquisition in Spain. Operating income surged 29% to Ps.1,023 million and operating margin rose to 11.4% from 9.2%, which came from the U.S. operations, in particular the tortilla business. In absolute terms, the depreciation of the euro partially offset the U.S. improvement. EBITDA increased 20% to Ps.1,312 million. EBITDA margin climbed to 14.6% from 12.7%.

GIMSA Sales volume was stable at 448 thousand metric tons. Corn flour sales volume rose 2% due mainly to (1) higher sales to tortilla makers driven by commercial initiatives; and (2) higher intercompany sales to the U.S. operations to support its growth. Sales volume of byproducts for animal feed declined significantly as, effective April 2015, this operation will no longer be part of GIMSA as it was restructured into a new subsidiary within Other Subsidiaries and Eliminations. Net sales grew 4% to Ps.3,933 million as GIMSA's revenues reflect Ps.116 million in extraordinary corn sales to Gruma Centroamerica. Also, net sales increased in connection with the change in the sales mix toward corn flour resulting from the aforementioned reduction of byproducts. Cost of sales as a percentage of net sales increased to 68.9% from 68.8% as a result of the aforementioned extraordinary corn sales at very low margins. In absolute terms, cost of sales rose 4% to Ps.2,710 million mostly due to the aforementioned extraordinary sale of corn. SG&A as a percentage of net sales increased to 16.2% from 15.7% and in absolute terms, SG&A rose 7% to Ps.638 million due mainly to the strengthening of the distribution initiatives to offer better customer service; and higher sales commissions. Operating income fell 3% to Ps.575 million in connection with the aforementioned increase in SG&A and the sale of real estate in 2Q14 for Ps.20 million. Operating margin declined to 14.6% from 15.6% due to the extraordinary corn sales to Gruma Centroamerica and higher SG&A. Excluding corn sales to Gruma Centroamerica, operating margin would have been 15.1%. EBITDA

Gruma Centroamerica Sales volume increased 6% to 53 thousand metric tons due to higher corn flour sales primarily in connection with (1) the World Food Programme in Honduras; and, to a lesser extent, (2) higher sales to government channels in Guatemala. Net sales increased 22% to Ps.1,014 million due mainly to the peso depreciation effect, and volume growth. Cost of sales as a percentage of net sales improved to 64.3% from 65.5% due to better cost absorption. In absolute terms, cost of sales rose 19% due mainly to the peso depreciation effect and the aforementioned volume growth. SG&A as a percentage of net sales improved to 27.1% from 27.5% resulting mostly from better expense absorption. In absolute terms, SG&A increased 20% to Ps.275 million due to (1) the peso depreciation effect; (2) higher commissions in connection with volume growth; and (3) an increase in marketing expenses. Operating income rose 49% to Ps.87 million and operating margin improved to 8.6% from 7.0% due primarily to the aforementioned sales volume growth. EBITDA increased 37% to Ps.109 million. EBITDA margin grew to 10.8% from 9.6%. Other Subsidiaries and Eliminations Operating income improved Ps.87 million to Ps.154 million. This resulted mainly from the positive peso depreciation effect related to Gruma Corporation, as figures for this subsidiary are reported under convenience translation and the foreign exchange benefit is shown under ''Other Subsidiaries and Eliminations.'' Also, better performance at the Asia-Oceania operations and the technology division contributed to the improvement in operating income.

The consolidated figures have been prepared in accordance with the International Financial Reporting Standards (IFRS).

International Accounting Standard 29 (IAS 29) defines the criteria to consider when a company operates under a hyperinflationary economic environment, which are when:

the general population prefers to keep its wealth in non-monetary assets or in a relatively stable foreign currency. Amounts of local currency held are immediately invested to maintain purchasing power;

the general population regards monetary amounts not in terms of the local currency but in terms of a relatively stable foreign currency. Prices may be quoted in that currency;

sales and purchases on credit take place at prices that compensate for the expected loss of purchasing power during the credit period, even if the period is short;

interest rates, wages, and prices are linked to a price index; and

the cumulative inflation rate over three years is approaching, or exceeds, 100%.

Based on the above, the GRUMA's consolidated figures are determined as follows: the figures for subsidiaries in Mexico, the United States, Europe, Central America, Asia and Oceania operate in a non-hyperinflationary environment; therefore the effects of inflation are not recognized. Results for foreign subsidiaries that operate in a non-hyperinflationary environment are translated to Mexican pesos applying the historical exchange rate. Under the section Subsidiary Results of Operations and the table of Financial Highlights by Subsidiary of this report, figures for Gruma Corporation were translated to Mexican pesos using a convenience translation with the exchange rate of Ps.15.5676/dollar as of June 30, 2015. The differences between the use of convenience translation and the historical exchange rate are reflected under ''Other Subsidiaries and Eliminations''.

INFORMATION ON DERIVATIVE AND FINANCIAL INSTRUMENTS

I. Qualitative information.A. Management's Discussion of the Policies for the use of Derivative Financial Instruments, and Purposes of the Same.

1. Derivative financial instruments contracting policies. Gruma's policies regarding financial instruments establish that the acquisition of any derivative financial instruments agreement must be associated with the hedging of an underlying operation of the company, such as the purchase of inventory or fuel consumption (commodities), interest payment at a determined rate, foreign currency payments at an exchange rate, among others. Gruma has a Risks Management policy that details the procedure to authorize their contracting. 2. General description of the objectives to use derivative financial instruments. The availability and price of corn and other agricultural commodities are subject to important fluctuations due to factors that are beyond our control, such as the weather, planting seasons, agricultural programs and government policies (both national and foreign), changes in the global supply/demand created by population growth, competitors and global production of similar harvests. The objective of using derivative financial instruments is to reduce the aforementioned risks. Likewise, in the normal course of business, Gruma enters into transactions in which it could be exposed to risks for changes in the interest rates or for fluctuations of exchange rates. The variations in the exchange rates can result from changes in the economic conditions, tax and monetary policies, volatile conditions, global markets liquidity, international and local political events, among others. In order to minimize these risks Gruma has entered into certain financial instruments. 3. Instruments used and hedging or negotiation strategies implemented. We hedge a part of our production requirements through futures and options contracts in order to minimize the risk generated by the fluctuations in the price and supply of corn, natural gas and diesel, risk that exists as an ordinary part of our business. Additionally, Gruma has entered into certain financial instruments such as interest rate swaps and foreign exchange financial instruments (FX). 4. Allowed negotiation markets and eligible counterparties.

In order to minimize the counterparty solvency risk, Gruma enters into derivative financial instruments only with major national and international financial institutions using mainly, when applicable depending on the derivative instrument used, the standard International Swaps and Derivatives Association, Inc. (''ISDA'') authorized forms and long form confirmation agreements. 5. Policies on the appointment of calculation or valuation agents. Gruma appoints the counterparties as calculation agents who periodically send the account statements of the open positions of the financial instruments. 6. Policies on margins, collaterals, credit lines, VAR. The Central Risks Committee of Gruma establishes that the derivative financial transactions may be performed with collaterals or using credit lines for that purpose. The majority of the executed transactions establish certain obligations on behalf of the Issuer to guarantee, from time to time, the differential between fair value and the credit line (risk margin) established with the respective financial institutions, consequently the timely compliance of those obligations are assured. Additionally, it is made clear that, upon failure to fulfill the obligations of providing collateral, the counterparty will have the right, but not the obligation, to early terminate the transactions in place, and to demand the corresponding consideration pursuant to the agreed terms. In addition and in order to maintain a risk exposure level within the boundaries authorized by the Central Risks Committee and the Audit Committee, the Corporate Treasury department reports, in a weekly and monthly manner, the information about the Derivative Financial Instruments to such organs, respectively, and quarterly to the Board of Directors. As of this date, Gruma has margin calls with their counterparty for $263,097 thousand pesos. 7. Internal control procedures to manage the exposure to market and liquidity risks. The Finance Department of each region in which the company has operations, evaluates the changes in the exposure of the derivative financial instruments and periodically informs them to the Corporate Financial & Planning Management, and the latter informs the General Management and the Central Risks Committee when the market conditions have materially changed. The execution of the derivative financial instruments is authorized pursuant to the guidelines set forth in the Risks Management policy of the company. 8. Existence of an independent third party who reviews the aforementioned procedures. The procedures are reviewed in the external audit process performed by PricewaterhouseCoopers, S.C. annually. 9. Information regarding the authorization of the use of derivatives and if there is a committee in charge of giving those authorizations and the derivatives risk management. All derivative financial transactions must be previously authorized by a Divisional Risks Committee and by the Central Risks Committee which is formed by members of the senior management and approved by the Audit Committee and the Board of Directors.

B. Generic Description of Valuation Techniques.

10. Description of methods, valuation techniques and valuation frequency:

Gruma determines the fair value based on recognized market prices. When not quoted in markets, fair value is determined using valuation techniques commonly used in the financial sector. Fair value reflects the credit risk of the instrument and includes adjustments to consider the credit risk of the Company or the counterparty, when applicable. Regarding purchases of corn, natural gas and diesel futures the market values of the US Chicago and New York futures exchanges are taken as reference, through the specialized Financial Institutions engaged for such purposes. These valuations are made periodically. 12. For hedging instruments, explanation of the method used to determine the effectiveness of the same, identifying the current available hedging level of the global position. Effectiveness of hedges is determined when the changes in fair value or cash flows of the underlying operation are offset by changes in fair value or cash flows of the hedging instrument in a ratio that falls within an inverse correlation range from 80% to 125%. When a hedge is no longer effective as well as when the hedge does not comply with the documentation requirements set forth in the International Financial Reporting Standards the results of the valuation of the financial instruments at their fair value are recognized in the income statement.

As of June 30, 2015, the open positions of financial instruments of corn that qualified as hedges had 100% of effectiveness.

C. Management discussion about the sources of liquidity that could be used to deal with derivative financial instruments.

13. Discussion about the internal and external sources of liquidity that could be used to attend the requirements related to derivative financial instruments.

There is potential liquidity requirements under our derivative financial instruments described in Section II below. Gruma plans to use its available cash flow as well as other available liquidity sources to satisfy such liquidity requirements.

D. Description of the changes in the exposure to major identified risks.

14. Description of the changes in the exposure to major identified risks, its management and contingencies that could affect it in future reports.

II. Sensibility Analysis

Corn and Fuels Derivative Financial Instruments:

According to the position as of June 30, 2015, a hypothetical 10 percent loss of the corn and fuels value would result in an additional adverse effect of $44,883 thousand pesos (for non-qualifying contracts).

Exchange Rate Derivative Financial Instruments: Based on our position as of June 30, 2015, a hypothetical appreciation of 10% of the Mexican peso against the United States dollar would result in an additional unfavorable effect of $231,527 thousand pesos. This sensitivity analysis is based in the value of the underlying assets given in the valuation made by the counterparty as of June 30, 2015, which includes the effects on the exchange rate variables, time and volatility.

* The sole purpose of the Company's acquisition of derivative financial instruments is hedging market and liquidity risks, notwithstanding, the accounting rules require specific documentation and evidence to classify a derivative financial instrument as a hedging instrument, and consequently the company classified its derivative financial instruments as negotiation instruments.
