SECOND QUARTER 2017 FINANCIAL REPORT ALFA REPORTS 2Q17 EBITDA OF U.S. $522 MILLION

ALFA, S.A.B. DE C.V. SECOND QUARTER 2017 FINANCIAL REPORT ALFA REPORTS 2Q17 EBITDA OF U.S. $522 MILLION Monterrey, N.L., Mexico, July 26, 2017.- ALFA, S.A.B. de C.V. (ALFA), a leading Mexican industrial company, reported today its 2Q17 unaudited financial results. Total revenues were U.S. $4,232 million, up 5% year-on-year due to higher sales achieved at all major business units. EBITDA was U.S. $522 million, down 19% vis-à-vis 2Q16, mainly explained by lower margins and inventory devaluation at Alpek, along with lower volumes and adverse metal lag impact in Nemak. Alvaro Fernandez, ALFA s President, commented on the Company s results: During the quarter, the Alfa companies delivered a mixed performance. We saw strong performance at Sigma mainly driven by its Mexican and European operations. In addition, solid results and the first phase of tower sales at Axtel also contributed positively to overall results. However, lower volumes in North America and adverse metal lag impacted Nemak s results, while the effect of lower oil prices and lower Polyester margins affected Alpek s performance. Consolidated capital expenditures and acquisitions amounted to U.S. $227 million during 2Q17. Net Debt at the quarter end of U.S. $6,401 million was 6% higher when compared to the U.S. $6,032 million in 2Q16. At the end of the quarter, financial ratios were: Net Debt to EBITDA: 3.0 times; Interest Coverage: 5.7 times. Majority Net Income was U.S. $76 million in 2Q17, compared to U.S. $46 million in 2Q16. This increase is mainly the result of lower operating results, which were offset by lower Comprehensive Financing Expense ( CFE ) due to lower foreign exchange losses during the quarter, compared to 2Q16.

ALFA S SECOND QUARTER 2017 2 SUMMARY OF GROUPS PERFORMANCE DURING 2Q17 Sigma s revenues amounted to U.S. $1,503 million, an increase of 4% versus 2Q16. By region, sales in Mexico increased 10% y-o-y in peso terms, reflecting higher volume and price adjustments to absorb the effect of a higher exchange rate on raw material costs. European sales continued to improve, increasing 3% in euro terms, while U.S. and Latin America increased 3% and 2% in dollar terms, respectively. In line with full year guidance, Sigma reported 2Q17 EBITDA of U.S. $167 million, down 1% year-on-year, mainly explained by a solid performance of Mexican operations which benefited benefitted from a more favorable currency environment, and strong results in Europe, which offset the start-up costs at new plant in Spain. In the U.S., results were impacted by a lag between price adjustments and recent cost increases on raw materials. On June 28, Sigma announced the acquisition of Sociedad Suizo Peruana de Embutidos, S.A. (SUPEMSA), a Peruvian company engaged in the production and sale of packaged meats and dairy products. In 2016, the company generated sales of U.S. $54.2 million. The acquisition was effective July 1 st, 2017. During 2Q17, capital expenditures totaled U.S. $50 million, funds were utilized for the new plant in Burgos, Spain, other fixed assets and minor projects across the company. At the end of 2Q17, Net Debt was U.S. $1,940 million, similar to 2Q16. Financial ratios at the end of 2Q17 were: Net Debt to EBITDA, 3.1 times; Interest Coverage, 4.4 times. (See appendix A for more comprehensive analysis of Sigma s 2Q17 financial results) Alpek s revenues for the second quarter totaled U.S. $1.3 billion, up 6% year-on-year, as lower average prices were more than offset by volume growth. 2Q17 consolidated volume was up 6%, while average 2Q17 consolidated prices were flat year-on-year, mainly due to lower feedstock prices. 2Q17 EBITDA was U.S. $82 million, down 61% from 2Q16. This quarter s EBITDA includes a U.S. $29 million non-cash inventory loss charge and a U.S. $12.5 million one-time gain from the acquisition of a controlling interest in Selenis Canada Inc. in 2016. Adjusting for the inventory loss and one-time gain, comparable EBITDA was U.S. $99 million and U.S. $190 million in 2Q17 and 2Q16, respectively. Comparable 2Q17 EBITDA was lower than expected as Polyester segment EBITDA was affected by higher costs associated with planned and unplanned outages, feedstock cost carryover and tight supply of secondary feedstock prices (IPA and CHDM) that had an estimated impact of U.S. $21 million. Accumulated EBITDA as of June 30, 2017 was U.S. $240 million. 2Q17 Capex was U.S. $65 million, compared to U.S. $110 million in 2Q16. The majority of these funds were invested in the 350 MW power cogeneration plant in Altamira, Mexico which is advancing as planned together with other projects such as the EPS plant expansion. An important milestone this quarter was the on-schedule startup of the company s propylene storage spheres in Altamira, Mexico. The acquisition of PetroquimicaSuape and Citepe from Petrobras for U.S. $385 million is advancing as planned. Alpek made an initial deposit of U.S. $39 million in escrow, and the Administrative Council for Economic Defense (CADE) in Brazil has begun evaluating the transaction. Closing is subject to CADE s approval, among other conditions. Net Debt as of the end of the quarter was U.S. $1,058 million, up 16% year-on-year, driven by the aforementioned investment in strategic projects. At quarter end, financial ratios were as follows: Net Debt to EBITDA, 2.0 times; Interest Coverage, 8.0 times. (See appendix B for Alpek s 2Q17 financial report) Nemak s 2Q17 sales volume was 12.8 million equivalent units, 2% lower than 2Q16. Sales volume declined in North America mainly due to lower demand from Ford and FCA, which reduced and discontinued production of certain vehicle

ALFA S SECOND QUARTER 2017 3 lines, respectively. Volumes in Europe remained flat during the quarter. By contrast, Rest-of-World volumes reported strong growth year-on-year, mainly due to the continued ramp-up of new programs in China. Higher aluminum prices supported revenues, which showed a 4% year-over-year increase. 2Q17 EBITDA totaled U.S. $206 million, down 7% year-on-year, mainly as a result of lower sales volumes in North America, negative metal price lag, and increased expenses associated with new programs. Additionally, the company recognized a non-recurring gain in the amount of U.S. $18 million derived from the reversal of a provision related to a disputed tax on revenues. EBITDA per unit was U.S. $16.10 in 2Q17, down from U.S. $16.90 in the same period last year. Capital expenditures in the quarter amounted to U.S. $88 million as the company continued to move ahead with strategic projects. Investments were made to increase production capacity to meet new demand coming from recently won contracts. Likewise, resources were dedicated to the plant under construction in Slovakia, which will produce structural and electric vehicle ( EV ) components starting in 2H17. Net Debt at the end of 2Q17 totaled U.S. $1,397 million, up 4% from 2Q16, reflecting the capital expenditures during the period. Financial ratios in 2Q17 were: Net Debt to EBITDA of 1.8 times, and Interest Coverage of 11.1 times. (See appendix C for Nemak s 2Q17 financial report) Axtel s revenues in the second quarter totaled U.S. $203 million, up 5% year-on-year, largely attributable to the Company s sales to Enterprise and Government segments as some legacy businesses are a drag on overall sales. Axtel has cycled the 2016 acquisition and results are now on a comparable basis. In peso terms, total revenues increased 9% in the quarter, reflecting 8% and 42% growth in enterprise and government segments, respectively, and flat mass-market segment results. Enterprise and government segment represented 80% of revenues in the quarter. 2Q17 EBITDA was U.S. $81 million, up 29% year-on-year, explained in part by a U.S. $17 million benefit from the first tranche of the tower sale. Excluding this effect, EBITDA increased 2% from 2Q16. In peso terms, EBITDA increased 32% year-on-year. In an effort to reduce FX volatility, Axtel entered into a second par-forward transaction that fixed the exchange rate for the interest and principal obligations denominated in dollars at 18.89 pesos per dollar from April to July 2018. Capital expenditures totaled U.S. $16 million in 2Q17 (U.S. $35 million, excluding tower sales), including investments to provide last-mile access to connect customers, to deploy IT infrastructure and to further increase data center capacity in Queretaro, Mexico. At the end of 2Q17, Net Debt was U.S. $1,027 million, up U.S. $20 million year-on-year. Financial ratios at the end of 2Q17 were: Net Debt to EBITDA of 4.1 times and Interest Coverage of 8.6 times. (See appendix D for Axtel s 2Q17 financial report) Newpek s revenues were slightly higher than 2Q16, as higher average oil and gas prices offset a decline in production. West Texas Intermediate (WTI) oil price was up 6% from 2Q16, averaging approximately U.S. $48 per barrel, and Henry Hub natural gas price increased 44% to an average of U.S. $3.1 per million BTU. Newpek connected to sales four new wells at the Eagle Ford Shale ( EFS ) in South Texas. This brought wells in production at EFS to 632 by the quarter s end, compared to the 628 wells in production at the end of 2Q16. Production in the U.S. averaged 4.2 million barrels of oil equivalent per day (MBOED) during 2Q17, down 46% from 2Q16 reflecting less drilling and normal decline rate. In line with the 2017 operating plan, strategic drilling and completion activities continued at EFS during the quarter. As a result, nine new wells are expected to be put into production during 3Q17 and seven during 4Q17, for a total of 20 new producing wells during the year. In Mexico, production averaged 3.7 MBOED during 2Q17, up 12% from 2Q16.

ALFA S SECOND QUARTER 2017 4 2Q17 revenues totaled U.S. $29 million, up 16% year-on-year, while EBITDA was U.S. $1 million, an improvement from the negative U.S. $2 million reported in 2Q16. Capital expenditures in the quarter amounted to U.S. $7 million. (See appendix E for more comprehensive analysis of Newpek s 2Q17 financial results) CONSOLIDATED FINANCIAL RESULTS 2Q17 consolidated revenues were U.S. $4,232 million, up 5% from U.S. $4,050 million reported in 2Q16. The increase is the result of higher sales across all business units and mainly reflects higher sales volume in Alpek, higher aluminum prices which offset lower volumes in Nemak, along with higher volumes and prices in Sigma. During the quarter, foreign sales represented 64% of the total, in line with 2Q16. Year-to-date revenues were U.S. $8,230, up 5% from 2016, primarily for the same reasons. 2Q17 Consolidated Operating Income totaled U.S. $278 million, down 33% from 2Q16, primarily due to weaker results at Alpek, as oil-related feedstocks resulted in a U.S. $29 million inventory devaluation during the quarter, compared to a U.S. $19 million inventory revaluation in 2Q16. In addition to lower results in the Polyester business mostly due to rising comonomer prices and further PET margin erosion; lower margins at Nemak stemming mainly from lower sales volume in North America and a reversal of metal lag effect also contributed to the decline. These items were partially offset by a nonrecurring gain of U.S. $18 million from the reversal of a provision related to a disputed tax on revenues. In turn, Axtel s operating income benefitted by extraordinary income of U.S. $17 million stemming from the sale of transmission towers, while Sigma was flat from 2Q16. Accumulated Operating Income was U.S. $571 million, down 28% from 2016. 2Q17 EBITDA was U.S. $522 million, down 19% year-on-year, reflecting the lower Operating Income explained above. Yearto-date EBITDA was U.S. $1,050 million, down 14% from 2016. ALFA reported 2Q17 Comprehensive Financing Expense (CFE) of U.S. $113 million, compared to U.S. $321 million in 2Q16, mainly explained by lower foreign exchange losses during the quarter than those reported in 2Q16. Majority Net Income was U.S. $76 million in 2Q17, compared to U.S. $46 million in 2Q16. This year-on-year increase is mainly explained by lower operating results offset by lower CFE already explained. Year-to-date Majority Net Income was U.S. $230 million, up 22% from the same period in 2016. CAPITAL EXPENDITURES AND ACQUISITIONS; NET DEBT Consolidated capital expenditures and acquisitions totaled U.S. $227 million in 2Q17. All subsidiaries continued to make progress on their investment plans as discussed in the initial section of this report. At quarter-end 2Q17, ALFA s Net Debt amounted to U.S. $6,401 million, U.S. $369 million higher than 2Q16. At the end of the quarter, financial ratios were: Net Debt to EBITDA, 3.0 times; Interest Coverage, 5.7 times. These ratios compare to 2.5 times and 7.1 times, respectively in 2Q16.

ALFA S SECOND QUARTER 2017 10 SIGMA REFRIGERATED FOOD PRODUCTS 36% AND 31% OF ALFA S REVENUES AND EBITDA IN 2Q17 Sigma is a leading multinational refrigerated food company that produces, markets and distributes quality branded foods, including packaged meats, cheese, yogurt and other refrigerated and frozen foods. Sigma has a diversified portfolio of leading brands and operates 68 plants in 17 countries across its four key regions: Mexico, Europe, the United States, and Latin America. INDUSTRY COMMENTS During 2Q17, the consumer markets were mixed across Sigma s main regions of operations. In Mexico, the average consumer confidence index reported by INEGI (Instituto Nacional de Estadística y Geografía National Institute for Statistics and Geography) was down 6% year-on-year, but up 15% from 1Q17. In turn, 2Q17 same-store sales reported by the National Association of Supermarkets and Department Stores (ANTAD) increased 5.7% year-on-year in nominal pesos. In Europe, according to the European Commission, the average consumer confidence index for 2Q17 improved to negative 2.7, reaching a 10-year high. In the U.S., the index increased to 118.6 in 2Q17 as reported by The Conference Board, the highest since 2000. Food retail sales reported by the U.S. Census Bureau increased 2% year-on-year, below the 3% year-onyear growth in 1Q17. Key raw material prices were mixed during the quarter and varied by region. In the Americas, the price of Sigma s raw materials increased when compared to 2Q16 levels. Turkey thigh and milk prices were up 14% and 11%, respectively, although they were still below the record-high levels observed in 2013 and 2014. Conversely, turkey breast was 34% lower, while pork hams were slightly lower than last year. In Europe, pork prices have increased since the second half of 2016 which resulted in 2Q17 prices 26% above the same year-ago period. In Mexico, the recent appreciation of the Peso vis-a-vis the U.S. Dollar has eased the pressure in the cost of raw materials, as the industry participants import most of its meats from the U.S. OPERATIONS During 2Q17, Sigma sold approximately 436 thousand tons of food products, up 2% from 2Q16, supported by growth in Mexico and USA. In dollar terms, average prices increased 2% year-on-year mainly due to higher prices in Mexico and Europe. FINANCIAL RESULTS 2Q17 Revenues totaled U.S. $1,503 million, 4% higher than 2Q16, driven by higher sales volume and prices. In Mexico, sales in pesos were 10% higher year-on-year, reflecting higher sales volumes and price adjustments to absorb higher raw material costs. In Europe, sales in euros were 3% above 2Q16 driven by higher prices. In the U.S., sales increased 3% yearon-year. Sales in Mexico accounted for 42% of the quarter s total, while Europe represented 34%, the U.S. 17%, and Latin America 7%. During the first half of 2017, revenues were U.S. $2,853 million, up 2% when compared to the same period of 2016. In line with full year guidance, Operating Income and EBITDA were U.S. $116 million and U.S. $167 million in 2Q17, down 3% and 1% year-on-year, respectively. This was primarily due to a strong performance from Mexican operations which benefitted from a more favorable currency environment, and positive results in Europe, which partially offset the start-up

ALFA S SECOND QUARTER 2017 11 costs of the new Burgos plant in Spain. In the U.S., results were affected by a lag between price adjustments and the recent cost increases on raw materials. CAPITAL EXPENDITURES AND ACQUISITIONS; NET DEBT During 2Q17, capital expenditures totaled U.S. $50 million, funds were utilized for the new plant in Burgos, Spain, other fixed assets and minor projects across the company. On June 28, 2017 Sigma announced the acquisition of Sociedad Suizo Peruana de Embutidos, S.A. (SUPEMSA), a Peruvian company engaged in the production and sale of packaged meats and dairy products. With 2016 revenue of U.S. $54 million, SUPEMSA is a leader in the production of premium packaged meats, with more than 25 years of successfully marketing its products under highly recognized local brands such as Otto Kunz and La Segoviana. The acquisition was effective July 1st, 2017. Sigma s consistent cash flow generation enables the company to finance capital expenditures and to maintain a solid financial position. At the end of 2Q17, Net Debt was U.S. $1,940 million, similar to 2Q16. Financial ratios at the end of 2Q17 were: Net Debt to EBITDA, 3.1 times; Interest Coverage, 4.4 times. These ratios compare with those reported in 2Q16, of 2.3 times and 7.8 times, respectively, which includes insurance income in EBITDA from the Bureba Fire.

Second Quarter 2017 (2Q17) Message from the CEO Alpek s second quarter 2017 EBITDA reflects lower than expected Polyester segment EBITDA amid a weak oil and feedstock price environment. In contrast with the favorable trends observed in 2Q16 and 1Q17, the average price per barrel of Brent crude posted its lowest level year-to-date at the end of 2Q17. Reference U.S. contract prices for paraxylene (Px) and propylene dropped 10% and 26% respectively, from March to June, driven by lower oil prices as well as normalized propylene supply. This quarter s abrupt feedstock price movements had a U.S. $39 million impact on Alpek s 2Q17 consolidated EBITDA, comprised of a U.S. $29 million non-cash inventory loss and an estimated U.S. $10 million from feedstock cost carryover in both business segments. The oil-related impact on Alpek s 2Q17 consolidated EBITDA was partially offset by a U.S. $12 million onetime gain associated to the acquisition of a controlling interest in Selenis Canada Inc., in 2016. Adjusting for the U.S. $29 million non-cash inventory loss and the U.S. $12 million one-time gain from the Canadian acquisition, Alpek s 2Q17 Comparable EBITDA was U.S. $99 million; below guidance as a result of subpar Polyester segment performance. Polyester segment EBITDA was U.S. $33 million in 2Q17. Adjusting for its U.S. $25 million non-cash inventory loss and the U.S. $12 million one-time gain, Comparable 2Q17 Polyester EBITDA was U.S. $45 million. This quarter s higher costs associated to planned and unplanned outages, feedstock cost carryover and tight supply of secondary feedstocks (IPA and CHDM) had an estimated impact of U.S. $21 million in Comparable Polyester EBITDA. 2Q17 Plastics & Chemicals (P&C) EBITDA was U.S. $49 million and Comparable segment EBITDA was U.S. $54 million; above Alpek s 2017 guidance driven by our polypropylene (PP) business. Year-to-date, PP margins have been better than expected despite high propylene price volatility. Capex totaled U.S. $65 million in 2Q17 as progress is ongoing in the development of strategic projects. An important milestone this quarter was the on-schedule startup of our propylene storage spheres in Altamira, Mexico. We invested a total of U.S. $23 million in two storage spheres with an aggregate capacity of 5,000 tons that will enhance the efficiency of our domestic propylene logistics chain and provide greater import flexibility. The acquisition of PetroquimicaSuape and Citepe from Petrobras for U.S. $385 million is advancing as planned. Alpek made an initial deposit of U.S. $39 million in escrow, and the Administrative Council for Economic Defense (CADE) in Brazil started evaluating the transaction. Closing is subject to CADE s approval, among other conditions. The formal process to monetize our power cogeneration assets is also underway. Alpek concluded the first phase of the sale process in 2Q17, and is engaged in a detailed due diligence with selected investors to reach a potential agreement. Alpek s Net Debt totaled U.S. $1.058 billion at the close of 2Q17, down 10% quarter-on-quarter as low EBITDA was more than offset by positive Net Working Capital cash flow. We expect Alpek s Consolidated EBITDA to return to guidance levels in 2H17 as a result of stable Polyester plant operations, secondary feedstock price transfer initiatives, and a normalized oil price environment. Year-to-date Comparable Consolidated EBITDA plus the one-time gain from the Canadian acquisition was U.S. $243 million, which compares with U.S. $246 million EBITDA for 1H17, implicit in Alpek s U.S. $502 million guidance. ir@alpek.com www.alpek.com 2

Second Quarter 2017 (2Q17) Results by Business Segment Polyester (Purified Terephthalic Acid (PTA), Polyethylene Terephthalate (PET), Polyester fibers 71% of Alpek s Net Sales) Second quarter 2017 Polyester revenue was up 7% year-on-year and 2% quarter-on-quarter as lower average prices were more than offset by volume growth. Average 2Q17 Polyester prices decreased 2% when compared with 2Q16 and 4% versus 1Q17, mainly due to lower feedstock prices. The U.S. contract Px price posted its lowest level year-to-date in June. 2Q17 Polyester volume was up 9% and 6% versus 2Q16 and 1Q17 respectively. Year-to-date, Polyester volume is 5% higher than 2016 as growth associated to the integration of Selenis Canada Inc. (PET) was partially offset by lower than expected PET volume in Mexico and Argentina. Second quarter 2017 segment EBITDA was U.S. $33 million, including a U.S. $25 million non-cash inventory loss and a U.S. $12 million one-time gain from the acquisition of a controlling interest in Selenis Canada Inc. (in 2016). Adjusting for the inventory loss and one-time gain, Comparable 2Q17 Polyester EBITDA was U.S. $45 million, down 53% and 34% versus 2Q16 and 1Q17 respectively. Certain events had a negative impact on Polyester profitability. Market events include this quarter s decline in Px and monoethylene glycol (MEG) prices which causes a temporary mismatch between end-product sale prices and feedstock costs. In addition, tight supply of secondary feedstocks used to produce PET (IPA and CHDM) resulted in incremental costs. This increase has not been completely transferred to PET prices. Moreover, planned and unplanned plant outages resulted in higher than expected 2Q17 conversion and logistics costs. On aggregate, these events had an estimated impact of U.S. $21 million in Comparable 2Q17 Polyester EBITDA. Plastics & Chemicals (P&C) (Polypropylene (PP), Expandable Polystyrene (EPS), Caprolactam (CPL), Other products 29% of Alpek s Net Sales) 2Q17 P&C revenue was up 2% year-on-year and flat quarter-on-quarter as a result of mixed price and volume movements. Average second quarter 2017 P&C prices increased 6% when compared with 2Q16 driven mainly by higher styrene prices. In contrast, the 2% average P&C price decrease versus 1Q17 reflects lower propylene and styrene prices. Second quarter 2017 P&C volume was down 3% versus 2Q16 and up 2% when compared to 1Q17. P&C volume posted its highest level year-to-date in June as feedstock prices appear to have normalized after an extended period of consecutive monthly declines. Segment EBITDA was U.S. $49 million, including a U.S. $5 million non-cash inventory loss. Adjusting for the inventory loss, Comparable 2Q17 P&C EBITDA was U.S. $54 million, down 43% versus 2Q16 which benefited from higher PP margins. Yet, Comparable 2Q17 P&C EBITDA was above guidance, driven mainly by better than expected PP margins and volume amid a volatile feedstock price environment. ir@alpek.com www.alpek.com 3

Second Quarter 2017 (2Q17) Consolidated Financial Results Net Sales: Net Sales for the second quarter totaled U.S. $1.3 billion, up 6% year-on-year and 1% quarter-onquarter, as lower average prices were more than offset by volume growth. 2Q17 consolidated volume was up 6% and 5% versus 2Q16 and 1Q17 respectively. Average 2Q17 consolidated prices were flat year-on-year and decreased 4% when compared with 1Q17, mainly due to lower feedstock prices. Accumulated net sales as of June 30, 2017 totaled U.S. $2.6 billion, 7% higher than the same period last year as a result of 5% and 3% increases in average prices and volume respectively. EBITDA: 2Q17 EBITDA was U.S. $82 million, down 61% and 48% when compared with 2Q16 and 1Q17 respectively. This quarter s Consolidated EBITDA includes a U.S. $29 million non-cash inventory loss and a U.S. $12 million onetime gain from the acquisition of a controlling interest in Selenis Canada Inc. (in 2016). Adjusting for the inventory loss and one-time gain, Comparable Consolidated EBITDA was U.S. $99 million, U.S. $131 million and U.S. $190 million in 2Q17, 1Q17 and 2Q16 respectively. Comparable 2Q17 Consolidated EBITDA was lower than expected as Polyester segment EBITDA was affected by a combination of internal and external events that had an estimated impact of U.S. $21 million. Accumulated EBITDA as of June 30, 2017 was U.S. $240 million and accumulated Comparable Consolidated EBITDA totaled U.S. $230 million. Year-to-date Comparable Consolidated EBITDA plus the one-time gain from the Canadian acquisition was U.S. $243 million, which compares with U.S. $246 million EBITDA for the first half of the year, implicit in Alpek s U.S. $502 million 2017 EBITDA guidance. Profit (Loss) Attributable to Controlling Interest: Profit Attributable to Controlling Interest for the second quarter of 2017 was U.S. $25 million, compared to U.S. $48 million and U.S. $87 million in 2Q16 and 1Q17 respectively. 2Q17 Profit Attributable to Controlling Interest decreased versus 2Q16 and 1Q17 as a result of a lower Operating Income. Accumulated Profit Attributable to Controlling Interest as of June 30, 2017 was U.S. $112 million, down 7% when compared to the same period in 2016 as this year s Fx gain and lower Income Tax were more than offset by the decrease in Operating Income. Capital Expenditures and Acquisitions (Capex): 2Q17 Capex was U.S. $65 million, compared to U.S. $110 million and U.S. $76 million in 2Q16 and 1Q17 respectively. Year-to-date, Capex of U.S. $142 million is flat vs the same period last year. The majority of these funds were invested in the 350 MW power cogeneration plant in Altamira, Mexico, which is advancing as planned together with other projects such as the EPS plant expansion. An important milestone this quarter was the on-schedule startup of our two propylene storage spheres in Altamira, Mexico. Net Debt: Consolidated Net Debt as of June 30, 2017 was U.S. $1.058 billion, up 16% year-on-year and down 10% quarter-on-quarter. On an absolute basis, Net Debt decreased U.S. $118 million during 2Q17 driven by positive Net Working Capital cash flow. Gross Debt as of June 30, 2017 was U.S. $1.246 billion, up 12% vs 2Q16 and down 4% when compared to 1Q17. 2Q17 Cash and Cash equivalents balance was U.S. $188 million. Financial ratios as of June 30, 2017 were: Net Debt to LTM EBITDA of 2.0 times and Interest Coverage of 8.0 times. ir@alpek.com www.alpek.com 4

Nemak posts 2Q17 EBITDA 1 of US$206 million Monterrey, Mexico. July 26, 2017. - Nemak, S.A.B. de C.V. ( Nemak ) (BMV: NEMAK), a leading provider of innovative lightweighting solutions for the global automotive industry, announced today its operational and financial results for the second quarter of 2017 ("2Q17"). What follows is an overview of the quarter s main highlights: Key Figures For 2Q17, volumes decreased 2.3% year-over-year ("y-o-y") as a decline in North America ("NA") more than offset higher volumes in the Rest of World ("RoW") region and stable volumes in Europe ("EU"). Meanwhile, revenues were up 3.8% y-o-y, as higher average aluminum prices passed on to customers more than compensated for lower volumes. For 1H17, volume increased slightly, while revenues were 4.1% higher y-o-y mainly due to increased aluminum prices. 2Q17 EBITDA was US$206 million, a 6.8% y-o-y decrease. In addition to a difficult comparison visà-vis the same period in 2016, when Nemak reported a positive effect related to the time it takes to fully pass through changes in aluminum prices to customers ("metal price lag"), Nemak saw three main negative effects this quarter: lower volumes in NA; negative metal price lag; and increased expenses associated with new programs. On the positive side, RoW reported a strong result, driven mainly by the Chinese operations. Furthermore, Nemak recognized a non-recurring gain in the amount of US$18 million for the reversal of a provision related to a disputed tax on revenues. On a cumulative basis, 1H17 EBITDA was US$396 million, 7.9% lower than 1H16 primarily due to the same reasons already explained. 2Q17 capex was US$88 million as the company continued with investments to increase and adapt production capacity to meet new demand coming from recently won contracts. Likewise, resources were dedicated to the plant under construction in Slovakia, which will produce structural and electric vehicles ( EV ) components starting in 2H17. For 1H17, capex amounted to US$231 million. Message from the CEO This quarter, we continued to make progress in our growth strategy while at the same time weathering external headwinds including lower demand from FCA and Ford in North America and 1 EBITDA = Operating Income + Depreciation, Amortization & other Non-Cash Charges April 24, 2017 1

negative metal price lag due to rising aluminum prices that weighed on our results. Higher expenses related to new program launches also hindered our financial performance, particularly in Europe. Meanwhile, our China operation remained on an upward trend, driving our RoW results higher in the quarter. I want to emphasize our positive outlook on our business in China, where our results have gotten progressively better in recent years on the back of improved scale, product mix, and performance. Moreover, given our backlog of new programs and open bids, we expect RoW to remain our fastestgrowing region through 2020. Turning to strategic projects, I am pleased to share that we continued the scale-up of our structural and electric vehicle components businesses. This included successfully launching a new program for Alfa Romeo out of our plant in Poland and transferring production of a program for Audi s new Q5 SUV from Poland to Mexico. Additionally, we announced the creation of a global organization dedicated to structural and electric vehicle components, whose leader reports directly to me. We expect that this organization will help us drive growth in these promising new business lines across our regions. Automotive Industry In the quarter, SAAR for U.S. vehicle sales was down 3% compared to 2Q16, as a stable retail market was not enough to offset lower fleet sales. Meanwhile, North America vehicle production and Nemak customers vehicle production decreased 2.7% and 2.0%, respectively, mainly due to lower production of passenger cars as their demand softened. In Europe, vehicle sales SAAR in 2Q17 remained flat y-o-y, as a slight increase in sales in Eastern Europe offset lower sales in Western Europe. However, vehicle production and Nemak customers production decreased 3.0% and 4.1%, respectively, as some OEMs adjusted their production schedules for inventory management reasons. Recent Developments Nemak successfully transferred a new program to produce structural components for the Audi Q5 from Poland to Mexico. This is Nemak s first program in NA in this business line. Nemak started development of E-drive housings in Europe and North America using proprietary casting processes. July 26, 2017 2

Nemak began working with an Asian customer on the development of battery tray prototypes for a new electric vehicle model slated for the North American market. Financial Results What follows is an explanation of the results shown in the table above: 2Q17 total volume decreased by 2.3% y-o-y to 12.8 million equivalent units, with FCA s 2016 discontinuation of its small- and- medium-size sedan lines in NA explaining the majority of the decrease and creating a difficult y-o-y comparison. Other Nemak customers, Ford in particular, also reduced demand due to lower sales of passenger cars. Regarding Europe, 2Q17 volume was flat y-o-y. Meanwhile, in RoW, volumes reported a strong y-o-y increase mainly due to the continued ramp-up of new programs in China. Despite the decrease in NA, 1H17 volume was slightly higher than 1H16 thanks to growth in Europe and RoW. Turning to revenues, the effect of higher aluminum prices more than compensated for declining volumes, causing Nemak s 2Q17 consolidated revenues to increase 3.8% y-o-y. Similarly, rising aluminum prices brought revenues 4.1% higher during 1H17. 2Q17 operating income decreased 12.7% y-o-y, mainly as a result of lower sales volumes, negative metal price lag, and increased expenses related to new programs. These factors were partially offset by the non-recurring gain already mentioned. The comparison vis-a-vis 2Q16 was even more difficult taking into account that the metal price lag effect had been positive that quarter. Lower operating income translated into an operating margin of 10.6%, 210 basis points below 2Q16. On a cumulative basis, 1H17 operating income was 14.1% lower than 1H16, for the reasons already explained. The above-mentioned decrease in operating income resulted in a 6.8% y-o-y reduction in EBITDA. 2Q17 EBITDA margin was 17.7%, down from the 19.7% reported in 2Q16. 2Q17 EBITDA per equivalent unit was US$16.10, down from US$16.90 in 2Q16. On a cumulative basis, the lower 1H17 operating income affected 1H17 EBITDA, which was 7.9% lower than 1H16 for the reason already mentioned. 1H17 EBITDA margin and EBITDA per equivalent unit were 17.3% and US$15.20, respectively, which compared to 19.6% and US$16.60 in 1H16. July 26, 2017 3

2Q17 net income increased 1.3% compared to 2Q16 as foreign exchange effects reduced deferred tax provisions. 1H17 net income was 16.7% lower than 1H16, mainly due to lower operating results. Capital expenditures totaled US$88 million during 2Q17. As explained, investments were made to expand capacity in various regions, and to facilitate operational efficiency. For 1H17, capital expenditures amounted to US$231 million. As of June 30, 2017, Nemak reported Net Debt in the amount of US$1.4 billion, including Cash and Marketable Securities worth US$108 million. Financial ratios were: Debt, net of Cash, to EBITDA, 1.8 times; Interest Coverage, 11.1 times. These ratios are slightly above those reported at the end of 2Q16. Regional Results North America In 2Q17, revenues increased 0.8% y-o-y benefiting from higher aluminum prices, which more than compensated for the impact of lower volumes in the region. Turning to EBITDA, lower volumes and the adverse impact of metal price lag were the main causes of the 2.8% decrease y-o-y. This result includes the non-recurring revenue gain in the amount of US$18 million derived from the reversal of a provision related to a longstanding dispute on tax on revenues in Brazil. The gain was recorded at the holding company level, which for presentation purposes has been considered a part of North America. Europe In 2Q17, revenues in Europe increased 1.3% y-o-y mainly due to higher aluminum prices. Meanwhile, 2Q17 EBITDA decreased 21.1% y-o-y, mainly due to the effects of negative metal price lag and increased expenses related to new programs brought on stream in the quarter, and to a lesser extent, foreign exchange effects. Rest of the World (RoW) In 2Q17, revenues in RoW increased by 41.6% y-o-y reflecting a solid performance in China, with sales volumes growing 30.0%. 2Q17 EBITDA in RoW increased US$5 million in 2Q17 compared to 2Q16 due to higher profitability in Asia. ------------------ July 26, 2017 4
