AB InBev Announces Final Results of Cash Tender Offers for up to USD 2 Billion Aggregate Purchase Price of Three Series of USD Notes

12 June 2025 – Anheuser-Busch InBev SA/NV (“AB InBev”) (Euronext: ABI) (NYSE: BUD) (MEXBOL: ANB) (JSE: ANH) today announced the expiration and final results of offers by its wholly-owned subsidiaries Anheuser-Busch InBev Worldwide Inc. (“ABIWW”), Anheuser-Busch Companies, LLC (“ABC”) and Anheuser-Busch InBev Finance Inc. (“ABIFI”, and together with ABIWW and ABC, the “Companies”) to purchase for cash any validly tendered (and not validly withdrawn) and accepted notes up to an aggregate purchase price (excluding accrued and unpaid interest) of USD 2 billion (such amount, the “Aggregate Offer Cap”) of three series of USD notes (the “Notes”) issued by the Companies, across the Pool 1 Tender Offer and the Pool 2 Tender Offers, each with a separate Pool Offer Cap, as described in the table below (the “Tender Offers”).

The Tender Offers have been made upon the terms and subject to the conditions set forth in the offer to purchase dated 13 May 2025 (the “Offer to Purchase”). Except for the increase in the Pool 1 Offer Cap announced on 28 May 2025, the terms and conditions of the Tender Offers set forth in the Offer to Purchase remain unchanged. Terms not defined in this announcement have the meanings given to them in the Offer to Purchase.

The Tender Offers expired at 5:00 p.m., New York City time, on 11 June 2025. As announced on 28 May 2025, the Aggregate Offer Cap and the Pool 2 Offer Cap had not been reached as of the Early Tender Time of 5:00 p.m., New York City time, on 27 May 2025.

The Early Settlement Date for the Notes tendered prior to or at the Early Tender Time occurred on 30 May 2025.

Because the Pool 1 Offer Cap had been reached as of the Early Tender Time, the Companies will not accept any Pool 1 Notes tendered after the Early Tender Time for purchase.

After the Early Tender Time and prior to or at the Expiration Time, according to information provided by Global Bondholder Services Corporation, the Tender and Information Agent for the Tender Offers, an additional $4,287,000 aggregate principal amount of the Pool 2 Notes were validly tendered and not validly withdrawn. With respect to the Pool 2 Tender Offers, the Companies will accept for purchase all of the Pool 2 Notes validly tendered (and not validly withdrawn) after the Early Tender Time and prior to or at the Expiration Time. The Pool 2 Notes validly tendered after the Early Tender Time but prior to or at the Expiration Time and that are accepted for purchase will only receive the applicable Total Consideration, as announced on 28 May 2025, minus the Early Tender Payment of $30 per $1,000 principal

amount of Notes (plus accrued interest). The Final Settlement Date for the Pool 2 Notes tendered after the Early Tender Time and prior to or at the Expiration Time is expected to be 16 June 2025.

As a result, as of the Expiration Time, a total of $1,819,225,000 aggregate principal amount of the Notes were validly tendered and not validly withdrawn. With the completion of the Tender Offers, the Companies will have repurchased an aggregate principal amount of $1,819,225,000 of three series of their outstanding Notes, as set out in the table below:

All values are in US Dollars.

(a)  The $8,828,523,000 aggregate principal amount of 4.900% Notes due 2046 issued by ABIWW and ABC remaining outstanding after the Final Settlement Date will consist of (i) $8,806,284,000 outstanding principal amount of 4.900% Notes due 2046 issued by ABIWW and ABC (US03522AAJ97/03522AAJ9) and (ii) $22,239,000 outstanding principal amount of 4.900% Notes due 2046 issued by ABIWW and ABC (144A: US03522AAF75/03522AAF7& Reg S: USU00323AF97/U00323AF9).
