CONSOLIDATED RESULTS OF OPERATIONS3Q15 versus 3Q14

Sales volume increased 5% to 968 thousand metric tons, driven in particular by Gruma Corporation. Net sales rose 21% to Ps.15,313 million, due principally by (1) the weakness of the peso, which benefitted sales from Gruma Corporation when stated in peso terms; and (2) the aforementioned sales volume growth. Cost of sales as a percentage of net sales improved to 61.6% from 63.0%, reflecting better performance mostly at Gruma Corporation. In absolute terms, cost of sales increased 18% to Ps.9,425 million due to peso weakness and the aforementioned sales volume growth. Selling, general and administrative expenses (SG&A) as a percentage of net sales increased to 24.9% from 23.9% due mainly to a higher proportion of Gruma Corporation in the consolidated figures as well as higher expenses at Other Subsidiaries and Eliminations and Gruma Centroamerica. In absolute terms, SG&A rose 26% to Ps.3,813 million mainly in relation to the effect of the weaker peso. Operating income grew 27% to Ps.1,990 million, driven primarily by Gruma Corporation's performance and the positive effect of the peso depreciation. Operating margin rose to 13.0% from 12.4% led mostly by Gruma Corporation and, to a lesser extent, Gruma Centroamerica. EBITDA increased 25% to Ps.2,412 million. EBITDA margin expanded to 15.8% from 15.2%. Net comprehensive financing cost was Ps.88 million, a reduction of Ps.117 million most notably 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.452 million, Ps.216 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 23.8%. Discontinued operations were Ps.19 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.69 million, as 3Q14 figures included the results of GRUMA's former wheat flour operations, which were sold in December 2014. Majority net income increased 20% to Ps.1,383 million. Better operating performance and lower net comprehensive financing cost drove this improvement. As a percentage of net sales, majority net income was 9%.

FINANCIAL POSITIONSeptember 2015 versus June 2015

Balance Sheet Highlights Total assets were Ps.47,967 million, a rise of 8% reflecting increases primarily in: Property, plant, and equipment, resulting from the weaker peso and the company's expanded capital expenditures program during 2015. Inventories, in connection with the summer corn crop in Mexico, and, to a lesser extent, the peso depreciation. Total liabilities were Ps.26,692 million, 8% more, mainly as a result of higher debt in connection with the acquisition of a 2% stake of GIMSA, the weaker peso, and working capital requirements. Shareholders' equity totaled Ps.21,275 million, 7% more than at June 2015.

Debt Profile GRUMA's debt totaled US$753 million, US$17 million more than at June 2015 due to the aforementioned acquisition of a 2% stake in GIMSA for around US$25 million. Approximately 92% of GRUMA's debt is dollar-denominated.

CAPITAL EXPENDITURE PROGRAM GRUMA's capital expenditures totaled US$58 million during 3Q15, 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); (3) the construction of a tortilla plant in Malaysia; and (4) the increase in GIMSA's ownership by approximately 2%, which represented around US$25 million during July.

SUBSIDIARY RESULTS OF OPERATIONS3Q15 versus 3Q14

Gruma Corporation Sales volume rose 6% to 441 thousand metric tons. The volume increase was driven by both the U.S. and European operations. In the U.S., corn flour grew largely as a result of gaining share through the increased quality of our corn flour; and increased popularity of tortillas and corn chips in restaurants. The tortilla operations rose due mainly to the retail segment, reflecting the growth of the tortilla industry, which GRUMA has captured from increased distribution, shelf space gains, product assortment optimization, and new private-label supply agreements. The growth of the European operations reflected higher sales of grits to the beer and snack industries; higher sales of byproduct for animal feed; and the recent acquisition in Spain. Net sales grew 3% to Ps.9,909 million. Net sales rose at a lower rate than sales volume principally because of the depreciation of European currencies and, to a lesser extent, lower corn flour prices following price reductions implemented in October 2014. Cost of sales as a percentage of net sales improved to 60.1% from 61.6% driven largely by the U.S. tortilla operations as a result of (1) better sales mix by focusing on high-margin products, presentations and brands; (2) lower allowances; and (3) better fixed cost absorption in connection with volume growth. In absolute terms, cost of sales increased 1% to Ps.5,959 million related to the aforementioned sales volume growth. SG&A as a percentage of net sales improved to 27.9% from 28.1% driven mostly by the U.S. operations as a result of better absorption. In absolute terms, SG&A rose 2% to Ps.2,767 million, due to (1) the launch of the Mission brand in several countries within Europe; (2) the recent acquisition in Spain; (3) higher sales commissions related to sales volume growth and better sales mix at the U.S. tortilla business; and (4) increased marketing and advertising expenses in the U.S. tortilla business. Operating income surged 24% to Ps.1,126 million and operating margin rose to 11.4% from 9.4%, which came from the U.S. operations, in particular the tortilla business. In absolute terms, the depreciation of European currencies partially offset the U.S. improvement. EBITDA increased 18% to Ps.1,435 million. EBITDA margin climbed to 14.5% from 12.7%.

GIMSA Sales volume increased 2% to 463 thousand metric tons. Corn flour sales volume rose 5% due mainly to (1) tortilla producers as a result of the increased quality of our corn flour, better customer service, and targeted discounts, especially in low corn flour consumption regions; and (2) higher intercompany sales to the U.S. operations to support their growth. The increase was partially offset by the reclassification of byproducts for animal feed, an operation which, effective April 2015, is no longer part of GIMSA as it was incorporated into a new subsidiary within Other Subsidiaries and Eliminations. Net sales grew 4% to Ps.3,928 million in connection with the aforementioned sales volume growth, and a change in the sales mix towards corn flour. Cost of sales as a percentage of net sales increased to 68.7% from 68.5% as a result of higher corn costs, higher transportation costs due to longer distances as more corn was procured during the Sinaloa summer crop as opposed to imported corn, increases in other material costs in connection with the weaker peso. In absolute terms, cost of sales rose 4% to Ps.2,697 million mostly due to the aforementioned volume growth and higher costs. SG&A as a percentage of net sales decreased to 16.2% from 16.5% due to better absorption. In absolute terms, SG&A rose 2% to Ps.636 million due mainly to enhanced distribution to offer better customer service; and higher sales commissions. Operating income increased 3% to Ps.559 million. Operating margin declined to 14.2% from 14.4% as a result of the aforementioned higher costs and losses on natural gas hedging. EBITDA

Gruma Centroamerica Sales volume decreased 1% to 49 thousand metric tons due largely to more aggressive competition in corn flour in Honduras; and in the rice and hearts of palm segments. Net sales increased 22% to Ps.1,046 million due mainly to the peso depreciation effect. Cost of sales as a percentage of net sales improved to 61.1% from 64.5% due to lower raw material and energy costs. In absolute terms, cost of sales rose 16% as lower raw material and energy costs were offset by the peso depreciation effect. SG&A as a percentage of net sales increased to 29.0% from 26.6% due to (1) royalty fees to Gruma Holding; (2) strengthening of the sales team; and (3) higher marketing expenses. In absolute terms, SG&A surged 33% to Ps.304 million principally resulting from the weaker peso and, to a lesser extent, the aforementioned expenses. Operating income rose 53% to Ps.118 million and operating margin improved to 11.3% from 9.0% due primarily to the aforementioned lower costs and other income, net, related to an insurance claim recovery. EBITDA increased 44% to Ps.141 million. EBITDA margin grew to 13.5% from 11.5%. Other Subsidiaries and Eliminations Operating income improved Ps.147 million to Ps.186 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, in this case, is shown under ''Other Subsidiaries and Eliminations.'' Also, better performance at the Asia-Oceania operations 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.17.0073/dollar as of September 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 $270,635 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 September 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 September 30, 2015, a hypothetical 10 percent loss of the corn and fuels value would result in an additional adverse effect of $38,233 thousand pesos (for non-qualifying contracts). This sensitivity analysis is determined based on the underlying assets' values obtained from the valuation performed as of September 30, 2015.

Exchange Rate Derivative Financial Instruments: Based on our position as of September 30, 2015, a hypothetical appreciation of 10% of the Mexican peso against the United States dollar would result in an additional unfavorable effect of $67,481 thousand pesos. This sensitivity analysis is based in the value of the underlying assets given in the valuation made by the counterparty as of September 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.
