ARCOSDORADOS ANNOUNCES COMMENCEMENT OF CASH TENDER OFFER FOR

ANYAND ALL OF ITS OUTSTANDING 5.875% NOTES DUE 2027(CUSIP NOS. 03965U AC4 / G0457F AC1; ISINs US03965UAC45 / USG0457FAC17)

Montevideo,Uruguay, January 15, 2025– Arcos Dorados Holdings Inc. (NYSE: ARCO) (“Arcos Dorados” or the “Company”) today announced the commencement of an offer to purchase for cash any and all of its outstanding 5.875% Notes due 2027 (the “Notes”) (the “Offer”). The Offer is being made upon the terms and subject to the conditions (including the Financing Condition (as defined in the Offer to Purchase)) set forth in the offer to purchase dated January 15, 2025 (the “Offer to Purchase”) and the notice of guaranteed delivery (the “Notice of Guaranteed Delivery” and, together with the Offer to Purchase, the “Offer Documents”).

The table below summarizes certain payment terms for the Notes:

The Offer will expire at 8:00 a.m., New York City time, on January 23], 2025, or any other date and time to which Arcos Dorados extends the Offer (such date and time, as it may be extended, the “Expiration Time”). Holders of Notes must validly tender their Notes at or prior to the Expiration Time and not validly withdraw them at or prior to the applicable Withdrawal Deadline (as defined in the Offer to Purchase) in order to be eligible to receive the Consideration (as defined in the Offer to Purchase) plus accrued interest for such Notes. Tendered Notes may be validly withdrawn at any time at or prior to the Withdrawal Deadline but not thereafter.

The obligation of Arcos Dorados to purchase Notes in the Offer is conditioned on the satisfaction or waiver of certain conditions, including, without limitation, the Financing Condition, described in the Offer Documents. Arcos Dorados reserves the right, in its sole discretion, to amend or terminate the Offer at any time.

The Offer is being made in connection with an expected proposed offering of U.S. dollar denominated senior notes (the “New Notes”) to be issued by Arcos Dorados B.V., a subsidiary of Arcos Dorados (the “Proposed New Notes Offering”). The Proposed New Notes Offering will be exempt from the registration requirements of the U.S. Securities Act of 1933, as amended.

If an offering of New Notes is announced, tendering Holders who wish to tender their Notes for cash and also subscribe for the New Notes should quote a unique identifier code corresponding to the New

Notes being subscribed (“Unique Identifier Code”), which can be obtained by contacting any of the Dealer Managers, in their acceptance to DTC through the DTC Automated Offer Program (“ATOP”) or Electronic Acceptance Instruction. A Unique Identifier Code is not required for a Holder to tender its Notes, but if a tendering Holder wishes to subscribe for the New Notes, such Holder should obtain a Unique Identifier Code from a Dealer Manager and enter the Unique Identifier Code in its ATOP.

If the proposed offering of New Notes is announced, Arcos Dorados will review tender instructions received on or prior to the pricing date of the New Notes, and may give priority to those investors tendering with Unique Identifier Codes in connection with the allocation of New Notes. However, no assurances can be given that any Holder that tenders its Notes will be given an allocation of New Notes at the levels it may subscribe for, or at all.

The information and tender agent for the Offer is Global Bondholder Services Corporation. To contact the information and tender agent, banks and brokers may call +1 (212) 430-3774, and others may call U.S. toll-free: +1 (855) 654-2015 or email [email protected]. Additional contact information is set forth below.

Copies of each of the Offer Documents are available at the following web address: https://www.gbsc-usa.com/arcos/

Any questions or requests for assistance or for additional copies of this notice may be directed to the Dealer Managers at their respective telephone numbers set forth below or, if by any Holder, to such Holder’s broker, dealer, commercial bank, trust company or other nominee for assistance concerning the Offer.

The Dealer Managers for the Offer are:

This notice does not constitute or form part of any offer or invitation to purchase, or any solicitation of any offer to sell, the Notes or any other securities in the United States or any other country, nor shall it or any part of it, or the fact of its release, form the basis of, or be relied on or in connection with, any

2

contract therefor. The Offer is made only by and pursuant to the terms of the Offer Documents, and the information in this notice is qualified by reference to the Offer to Purchase and the Notice of Guaranteed Delivery. None of Arcos Dorados, the Dealer Managers or the information and tender agent makes any recommendation as to whether Holders should tender their Notes pursuant to the Offer.
