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, February 24, 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 fourth quarter of 2025.

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

“2025 tested our business in several ways, which provided the opportunity to demonstrate our ability to learn and adjust to changing conditions. It also underscored the resilience of our core business and reinforced the conviction on our strategy of following a sustainable long-term growth model. Through decisive actions to address short-term challenges—particularly in Mexico—and strong execution across South America, we delivered sequential volume improvements throughout the year. We ended the fourth quarter on a strong note, with consolidated volume growth and the highest December volumes in our Company’s history for our four largest operations.

Despite navigating a complex operating environment, our full-year results reflect top- and bottom-line growth with resilient margins, positive momentum in our competitive position, and significant progress in our digital and capacity initiatives.

As we look to 2026, we are well equipped to both address the impact of the increase in the IEPS tax in Mexico and accelerate growth in South America by leveraging our revenue-growth-management initiatives, increased brand engagement from the FIFA World Cup, and continuing to rollout our leading-edge digital capabilities. Combining our top-line initiatives, together with a lean and agile operating model, we are well positioned to continue delivering long-term sustainable growth.”

CONSOLIDATED fourth QUARTER RESULTS

Volume increased 1.3% to 1,093.6-million-unit cases, driven by volume growth in most of our operations that was partially offset by a slight decline in Mexico.

Total revenues increased 2.9% to Ps. 77,750 million. This increase was driven mainly by revenue management initiatives, partially offset by an unfavorable mix and currency translation into Mexican pesos from most of our operating currencies. Excluding currency translation effects, total revenues increased 6.0%.

Gross profit increased 1.8% to Ps. 36,321 million, and gross margin contracted 60 basis points to 46.7%. This contraction was driven mainly by an unfavorable mix and higher fixed costs such as labor and depreciation. These effects were partially offset 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. Excluding currency translation effects, gross profit increased 4.6%.

Operating income increased 13.3% to Ps. 13,702 million, and operating margin expanded 160 basis points to 17.6%. This margin expansion was positively impacted by the recognition of insurance claims recovered in Brazil and Mexico, net of expenses, for Ps. 1,149 million. By excluding insurance recovery and related expenses in the fourth quarter of 2024 and 2025, our operating income declined 2.1%, resulting in an operating margin contraction of 90 basis points to reach 16.1%. (After excluding the effects on adjusted EBITDA in both periods of 2024 and 2025, adjusted EBITDA increased by 4.4%, while the adjusted EBITDA margin expanded by 30 basis points.).

The normalized operating margin contraction is explained by higher depreciation and labor expenses, partially offset by expense controls such as maintenance and freight, coupled with an operating foreign exchange gain. Excluding currency translation effects, operating income increased 16.7%.

Coca-Cola FEMSA Reports 4Q25 Results February 24, 2026	Page 4 of 17

Comprehensive financing result recorded an expense of Ps. 1,357 million, compared to an expense of Ps. 980 million in the previous year. This increase was driven mainly by a higher interest expense, net, due to a reduction in interest income, coupled with an increase in interest expense. The reduction in interest income is explained mainly by a lower cash position in key markets and lower interest rates in Mexico, while the increase in interest expense was driven mainly by the issuance during the second quarter of a U.S. dollar-denominated bond due and its related derivative instruments.

This effect was partially offset by the recognition of a foreign exchange gain of Ps. 83 million in the fourth quarter of 2025 as compared to a gain of Ps. 57 million in the same period of the previous year. The gain this year was driven mainly by the quarterly appreciation of the Mexican peso and Brazilian real as applied to our U.S. dollar-denominated net debt position.

In addition, we recorded a gain in financial instruments of Ps. 162 million, as compared to a loss of Ps. 33 million recorded in the same period of the previous year, driven mainly by the valuation of short-to-mature financial instruments in Brazil.

Additionally, we recognized a higher gain in monetary positions in inflationary subsidiaries related to Argentina for Ps. 108 million as compared to a gain of Ps. 61 million recorded in the same period of the previous year.

Income tax as a percentage of income before taxes was 35.7% as compared to 33.1% during the same period of 2024. This increase was driven mainly by non-creditable taxes in Mexico, inflationary effects, and non-recurring effects from previous fiscal years.

Net income attributable to equity holders of the company increased 3.0% to reach Ps. 7,501 million. This was driven mainly by operating income growth, partially offset by an increase in our comprehensive financing result and in the effective tax rate. Earnings per share¹ were Ps. 0.45 (Earnings per unit were Ps. 3.57 and per ADS were Ps. 35.71.).

CONSOLIDATED full year RESULTS

Volume decreased 1.8% to 4,150.4-million-unit cases, driven mainly by volume declines in Mexico, Panama, and Colombia that were partially offset by volume growth in the rest of our operations.

Total revenues increased 4.3% to Ps. 291,746 million. This increase was driven mainly by revenue management initiatives, partially offset by a volume decline and unfavorable mix and currency translation effects from the Argentine peso into Mexican pesos. On a currency neutral basis, total revenues increased 6.5%.

Gross profit increased 3.4% to Ps. 133,176 million, and gross margin contracted 40 basis points to 45.6%. This contraction was driven mainly by higher promotional activity and an unfavorable mix, coupled with higher fixed costs such as labor. These effects were partially offset by lower sweetener costs and top-line growth. Excluding currency translation effects, gross profit increased 5.2%.

Operating income increased 7.0% to Ps. 42,937 million, and operating margin expanded 40 basis points to 14.7%. This margin expansion was positively impacted by the recognition of insurance claims recovered in Brazil and Mexico, net of expenses, for Ps. 1,432 million. By excluding insurance recoveries and related expenses in 2024 and 2025, our operating income declined 0.7%, resulting in an operating margin contraction of 70 basis points to reach 14.2%. (After excluding the effects on adjusted EBITDA in both periods of 2024 and 2025, adjusted EBITDA increased by 2.7%, while the adjusted EBITDA margin contracted by 30 basis points.).

This operating margin contraction, excluding the effects previously mentioned, was driven mainly by increases in labor, restructuring expenses, depreciation, and maintenance, partially offset by a decrease in freight expenses. In addition, we recognized an operative foreign exchange gain as compared to a loss in the previous year. Excluding currency translation effects, operating income increased 7.0%.

Coca-Cola FEMSA Reports 4Q25 Results February 24, 2026	Page 6 of 17

Comprehensive financing result recorded an expense of Ps. 4,945 million, compared to an expense of Ps. 3,906 million in the same period of the previous year. This increase was driven mainly by a higher interest expense, net, of Ps. 5,760 million as compared to Ps. 4,492 million in the same period of the previous year because of a higher interest expense driven mainly by our U.S. dollar-denominated bond due 2035 issued during the second quarter. Additionally, we recorded a reduction in our interest income driven by lower notional and interest rates in Mexico and Argentina.

Moreover, we recognized a foreign exchange gain of Ps. 20 million as compared to a gain of Ps. 304 million in the same period of the previous year. The gain this year was driven mainly by the appreciation of most of our operating currencies as applied to our U.S. dollar cash position partially offset by the appreciation of the Mexican peso as applied to our U.S dollar-denominated debt.

These effects were partially offset by a higher gain in financial instruments of Ps. 412 million as compared to a gain of Ps. 67 million in the same period of the previous year. Finally, we recognized a higher gain in monetary positions in inflationary subsidiaries related to Argentina for Ps. 383 million as compared to a gain of Ps. 216 million in the same period of the previous year.

Income tax as a percentage of income before taxes was 34.1% as compared to 32.7% during the same period of 2024. This increase was driven mainly by non-recurring effects and inflationary effects from previous fiscal years, coupled with non-creditable taxes.

Net income attributable to equity holders of the company was Ps. 23,845 million as compared to Ps 23,729 million during the same period of the previous year. This 0.5% increase was driven mainly by operating income growth, offset by an increase in our comprehensive financing result and in income taxes. Earnings per share¹ were Ps. 1.42 (Earnings per unit were Ps. 11.35 and per ADS were Ps. 113.50.).

MEXICO & CENTRAL AMERICA DIVISION FOURTH QUARTER RESULTS

Volume remained stable, driven by volume increases in all our Central America South operations and Guatemala, partially offset by a 0.9% volume decline in Mexico.

Total revenues increased 1.6% to Ps. 42,199 million. This performance was driven mainly by revenue management initiatives, offset by unfavorable mix effects and unfavorable currency translation effects from all our operating currencies into Mexican pesos. Excluding currency translation effects, total revenues increased 3.3%.

Gross profit increased 2.6% to Ps. 20,782 million, and gross margin expanded 40 basis points to 49.2%. 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, lower operating leverage, and higher fixed costs. Excluding currency translation effects, gross profit increased 4.4%.

Operating income decreased 1.1% to Ps. 6,868 million, and operating margin contracted 40 basis points to 16.3%. Our operating income includes the recognition of insurance claims in Mexico, net of expenses, for Ps. 116 million. By excluding insurance recoveries and related expenses in the fourth quarter of 2024 and 2025, our operating income declined 8.1%, resulting in an operating margin contraction of 170 basis points to reach 16.0%. (After excluding the effects on adjusted EBITDA in both periods of 2024 and 2025, adjusted EBITDA increased by 0.5%, while the adjusted EBITDA margin contracted by 20 basis points).

This operating margin contraction, excluding the effects previously mentioned, was driven mainly by an increase in operating expenses such as marketing, depreciation, and labor. In addition, this quarter we recognized a lower operative foreign exchange gain as compared to the previous year. These effects were partially offset by operating expense efficiencies such as maintenance and distribution expenses. Excluding currency translation effects, operating income increased 1.0%.

SOUTH AMERICA DIVISION FOURTH QUARTER RESULTS

Volume increased 3.0% to 504.1-million-unit cases, driven by volume growth across all the countries in the division.

Gross profit increased 0.6% to Ps. 15,539 million, and gross margin contracted 170 basis points to 43.7%. This contraction was driven by an unfavorable mix and higher fixed costs such as labor and depreciation.

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 refers 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 fourth quarter of 2025, as compared to the same period of 2024, we had an unfavorable currency translation effect into Mexican pesos. Please see page 17 for exchange rate fluctuations.
