Earnings Call 3Q25 This presentation was prepared by Ambev S.A. (“Ambev” or “Company”) for the exclusive use in
the earnings conference call of the third quarter of 2025 (3Q25). This presentation should not be considered as a complete document and
should be analyzed together with the Company’s quarterly information form (ITR/6-K) for the third quarter and the respective press
release, both available on the U.S. Securities and Exchange Commission –SEC and the CVM websites. This presentation was prepared
for informational purposes only and should not be considered as a solicitation or offer to buy or sell any securities of the Company,
or as advice or recommendation of any nature. This presentation is not intended to be comprehensive, or to contain all the information
that Ambev’s shareholders might need. No decisions on investment, disposal or any other financial decisions or actions shall be
made solely on the basis ofthe information contained herein. This presentation segregates the impact of organic changes from those arising
from changes in scope or currency translation. Scope changes represent the impact of acquisitions and divestitures, the start up or termination
of activities or the transfer of activities between segments, curtailment gains and losses and year over year changes in accounting estimates
and other assumptions that management does not consider as part of the underlying performance of the business. Organic growth and normalized
numbers are presented applying constant year-over-year exchange rates to exclude the impact of the movement of foreign exchange rates.
Unless stated, percentage changes in this press release are both organic and normalized in nature. Whenever used in this document, the
term “normalized” refers to performance measures EBITDA and Operating Profit before exceptional items and share of results
of joint ventures and to performance measures Profit and EPS before exceptional items adjustments. Exceptional items are either income
or expenses which do not occur regularly as part of the normal activities of the Company. They are presented separately because they are
important for the understanding of the underlying sustainable performance of the Company due to their size or nature. Normalized measures
are additional measures used by management and should not replace the measures determined in accordance with IFRS as indicators of the
Company’s performance. Comparisons, unless otherwise stated, refer to the third quarter of 2024 (3Q24). Values in this release may
not add up due to rounding. 3Q25 Operating Performance highlights 3Q25 Delivery +8% EPS growth EBITDA growth with margin expansion Net
