FIRST QUARTER 2026 RESULTS

INVESTOR RELATIONS Jorge Collazo | jorge.collazo@kof.com Lorena Martin | lorena.martinl@kof.com Bryan Silva | bryan.silva@kof.com Emilio Díaz | emilio.diaz@kof.com kofmxinves@kof.com

Mexico City, April 29, 2026, Coca-Cola FEMSA, S.A.B. de C.V. (BMV: KOFUBL, NYSE: KOF) (“Coca-Cola FEMSA”, “KOF” or the “Company”), the largest Coca-Cola franchise bottler in the world by sales volume, announces results for the first quarter of 2026.

Ian Craig, Coca-Cola FEMSA’s CEO, commented:

“Our first quarter results reflected the resiliency of our business and the advantages that a diversified footprint affords. Consolidated volume growth was supported by positive contributions from most of our operations, including strong performances in Argentina, Brazil, Colombia, and Guatemala that helped offset a volume decline in Mexico. As expected, we faced a softer consumer backdrop in Mexico compounded by the excise tax increase. Despite these headwinds, we gained share across most of our markets and categories and achieved record volumes for a first quarter in key markets such as Brazil, Colombia, and Guatemala. Our consolidated margins remained stable, supported by a strong performance in South America that compensated for pressures in Mexico and Central America. Unfavorable volume and mix impacts from the excise tax increase, severance and IT expenses resulted in a 17.4% drop in operating income in Mexico and Central America which was partially compensated by a 18.8% operating income growth in South America driven by volume growth and fixed costs and expenses absorption, resulting in a consolidated operating income decline of 2.3% for the quarter.

Looking ahead, we remain focused on strengthening our competitive position through targeted revenue management initiatives that support sustainable volume growth over the long term. Throughout 2026, we will also leverage the FIFA World Cup platform across our markets, while continuing to capture efficiencies and savings to protect profitability and prioritize the sustainable long-term growth of our business.”

CONSOLIDATED FIRST QUARTER RESULTS

Volume increased 1.2% to 998.4 million-unit cases, driven by volume growth in most of our operations that was partially offset by a decline in Mexico.

Total revenues increased 1.1% to Ps. 70,925 million. This increase was driven mainly by revenue management initiatives and a volume increase in most of our countries, partially offset by the negative translation effect from all our operating currencies into Mexican pesos. Excluding currency translation effects, total revenues increased 6.0%.

Gross profit increased 4.5% to Ps. 33,255 million, and gross margin expanded 150 basis points to 46.9%. This expansion was driven mainly by lower sweetener and PET costs, coupled with the appreciation of most of our operating currencies as applied to our U.S. dollar-denominated raw material costs. These effects were partially offset by higher fixed costs such as labor and depreciation, coupled with unfavorable mix effects. Excluding currency translation effects, gross profit increased 9.5%.

Operating income decreased 2.3% to Ps. 9,032 million, and operating margin contracted 50 basis points to 12.7%. This margin contraction was driven mainly by rightsizing initiatives and IT expenses, related to the implementation of SAP4Hana, in addition we recorded higher operating expenses such as marketing and depreciation. These effects were partially offset by expense efficiencies such as freight and maintenance across our operations. In addition, this quarter we recognized an income of Ps. 95 million, net of expenses, related to insurance claims from Hurricane John that impacted Mexico in September 2024. Excluding currency translation effects, operating income increased 2.6%.

Coca-Cola FEMSA Reports 1Q26 Results April 29, 2026	Page 4 of 14

Comprehensive financing result recorded an expense of Ps. 1,752 million, compared to an expense of Ps. 1,126 million in the previous year. This increase was driven mainly by a loss in financial instruments of Ps. 167 million, as compared to a gain of Ps. 135 million recorded in the same period of the previous year, driven mainly by an increase in rates and the valuation of matured financial instruments in Brazil.

In addition, we recorded a higher interest expense, net, because of an increase in interest expenses driven mainly by new bond issuances in U.S. dollars and Mexican pesos. Moreover, we recorded a reduction in interest income because of a lower cash position in key markets.

Additionally, we recognized a foreign exchange loss of Ps. 117 million in the first quarter of 2026 as compared to a loss of Ps. 59 million in the same period of the previous year. The loss this year was driven mainly by the quarterly appreciation of the Brazilian Real and the Costa Rican Colon as applied to our U.S. dollar-denominated cash position, coupled with the quarterly depreciation of the Mexican peso as applied to our U.S. dollar-denominated net debt position.

These effects were partially offset by the recognition of a higher gain in monetary positions in inflationary subsidiaries related to Argentina for Ps. 104 million as compared to a gain of Ps. 87 million recorded in the same period of the previous year.

Income tax as a percentage of income before taxes was 36.6% as compared to 33.4% during the same period of 2025. This increase was driven mainly by inflationary effects in Argentina and non-creditable taxes in Mexico.

Net income attributable to equity holders of the company decreased 15.5% to reach Ps. 4,342 million. This decrease was driven mainly by an increase in our comprehensive financing result, coupled with a decrease in our operating income. Earnings per share¹ were Ps. 0.26 (Earnings per unit were Ps. 2.07 and per ADS were Ps. 20.67.).

MEXICO & CENTRAL AMERICA DIVISION FIRST QUARTER RESULTS

(Mexico, Guatemala, Costa Rica, Panama, and Nicaragua)

Volume decreased 1.6% to 544.5 million-unit cases, driven by a volume decline in Mexico, partially offset by volume growth in the rest of our territories in the division.

Total revenues decreased 1.4% to Ps. 39,117 million. This performance was driven mainly by unfavorable mix and currency translation effects from all our operating currencies into Mexican pesos. These effects were partially offset by revenue management initiatives and volume increases in our territories in Central America. Excluding currency translation effects, total revenues increased 1.4%.

Gross profit increased 0.7% to Ps. 19,020 million, and gross margin expanded 100 basis points to 48.6%. This margin expansion was driven mainly by lower sweetener and PET costs, coupled with the appreciation of the Mexican peso as applied to our U.S. dollar-denominated raw material costs. These effects were partially offset by unfavorable mix effects. Excluding currency translation effects, gross profit increased 3.7%.

Operating income decreased 17.4% to Ps. 4,461 million, and operating margin contracted 220 basis points to 11.4%. Our operating income includes the recognition of insurance claims in Mexico, net of expenses, for Ps. 95 million.

This operating margin contraction was driven mainly by an increase in operating expenses such as marketing, depreciation, restructuring and IT. These effects were partially offset by operating expense efficiencies such as maintenance and distribution. Excluding currency translation effects, operating income decreased 14.2%.

SOUTH AMERICA DIVISION FIRST QUARTER RESULTS

(Brazil, Argentina, Colombia, and Uruguay)

Volume increased 4.8% to 453.9 million-unit cases, driven by volume growth across all the countries in the division.

Total revenues increased 4.3% to Ps. 31,809 million. This increase was driven mainly by volume growth and revenue management initiatives, offsetting an unfavorable currency translation from all our operating currencies into Mexican pesos. Excluding currency translation effects, total revenues increased 12.3%.

Gross profit increased 10.0% to Ps. 14,235 million, and gross margin expanded 230 basis points to 44.8%. This expansion was driven by lower sweetener and PET costs, coupled with the appreciation of most of our operating currencies as applied to our U.S. dollar-denominated raw material costs. These effects were partially offset by higher fixed costs such as depreciation. Excluding currency translation effects, gross profit increased 18.3%.

Operating income increased 18.8% to Ps. 4,571 million, resulting in an operating margin expansion of 180 basis points to 14.4%. This operating margin increase was driven mainly by operating leverage, coupled with expense efficiencies such as labor, partially offset by higher expenses such as marketing. Excluding currency translation effects, operating income increased 26.9%.

DEFINITIONS

Volume is expressed in unit cases. Unit case refers to 192 ounces of finished beverage product (24 eight-ounce servings) and, when applied to soda fountains, refers to the volume of syrup, powders, and concentrate that is required to produce 192 ounces of finished beverage product.

Transactions refer to the number of single units (e.g., a can or a bottle) sold, regardless of their size or volume or whether they are sold individually or in multipacks, except for soda fountains, which represent multiple transactions based on a standard 12 oz. serving.

Operating income is a non-GAAP financial measure computed as “gross profit – operating expenses – other operating expenses, net + operative equity method (gain) loss in associates.”

Adjusted EBITDA is a non-GAAP financial measure computed as “operating income + depreciation + amortization & other operating non-cash charges.”

Earnings per share are equal to “quarterly earnings / outstanding shares.” Earnings per share (EPS) for all periods are adjusted to give effect to the stock split resulting in 16,806,658,096 shares outstanding. For the convenience of the reader, as a KOFUBL Unit is comprised of 8 shares (3 Series B shares and 5 Series L shares), earnings per unit are equal to EPS multiplied by 8. Each ADS represents 10 KOFUBL Units.

COMPARABILITY

Our “comparable” term means, with respect to a year-over-year comparison, the change of a given measure excluding translation effects resulting from exchange rate movements. In preparing this measure, management has used its best judgment, estimates, and assumptions to maintain comparability.

Due to the average depreciation of the Argentine peso and most of the operating currencies relative to the Mexican peso in the first quarter of 2026, as compared to the same period of 2025, we had an unfavorable currency translation effect into Mexican pesos. Please see page 14 for exchange rate fluctuations.
