The Republic of Turkey (“Türkiye”) announced today the commencement of a global offering (the “New Notes Offering”) of new notes to be denominated in U.S. dollars (the “New Notes”). The New Notes Offering may include New Notes to be issued and sold to certain tendering holders in the Tender Offer (as described below).

Tender Offer

Türkiye also announced today that it has commenced an offer to purchase for cash (the “Tender Offer”) the Old Notes (as defined below) in an aggregate principal amount for each series that does not exceed an amount to be determined by Türkiye in its sole discretion (the “Maximum Purchase Amount”). The Tender Offer is made on the terms and subject to the conditions contained in the Tender Offer Memorandum, dated Tuesday, 24 September 2024 (the “Tender Offer Memorandum”), including the pricing of the issue of the New Notes in an amount and on terms and subject to conditions acceptable to Türkiye, which is expected to occur tomorrow. All capitalized terms used but not defined under the heading “Tender Offer” in this communication have the respective meanings specified in the Tender Offer Memorandum.

The tender period (“Tender Period”) will commence at or around 8:00 a.m., London time, on Wednesday, 25 September 2024. Unless extended or earlier terminated, the Tender Offer will expire at (i) 1:30 p.m., London time, that same day for Non-Preferred Tenders, and (ii) at 2:30 p.m., London time, that same day for Preferred Tenders. HOLDERS WILL ONLY BE ALLOWED TO SUBMIT TENDER ORDERS DURING THE TENDER PERIOD, AS SUCH MAY BE TERMINATED OR EXTENDED.

“Preferred Tenders” are Tender Orders that are submitted concurrently with the submission of an Indication of Interest for the New Notes for at least the same principal amount of New Notes as the principal amount of Old Notes submitted pursuant to such Tender Order. Preferred Tenders must be submitted during the period in which the underwriters for the New Notes Offering are accepting Indications of Interest. “Non-Preferred Tenders” are any Tender Order that is not a Preferred Tender. For both Preferred Tenders and Non-Preferred Tenders, Tender Orders must be of at least a principal amount of U.S.$1,000,000 and integral multiples of U.S.$1,000 in excess thereof (the “Permitted Tender Amounts”).

Türkiye expects to announce the Maximum Purchase Amount, the aggregate principal amount of Preferred Tenders and of Non-Preferred Tenders of the Old Notes that are expected to be accepted and whether any proration has occurred for any series of Old Notes on Thursday, 26 September 2024, or as soon as possible thereafter. The settlement of the Tender Offer is scheduled to occur on Tuesday, 1 October 2024 (the “Tender Offer Settlement Date”) but is subject to change without notice.

The Purchase Price to be paid for the Old Notes that are tendered and accepted pursuant to the Tender Offer will be the fixed price identified for each series of Old Notes set forth in the table below. Holders of the Old Notes participating in the Tender Offer will also receive any accrued and unpaid interest on their Old Notes up to (but excluding) the Tender Offer Settlement Date (“Accrued Interest”).

During the Tender Period, a holder of Old Notes may place orders to tender Old Notes (“Tender Orders”) only through any of the Dealer Managers. If a holder does not have an account with a Dealer Manager and desires to tender its Old Notes, it may do so through a broker, dealer, commercial bank, trust company, other financial institution or other custodian, in each case that has an account with a Dealer Manager. Holders will NOT be able to submit tenders through Euroclear Bank SA/NV, Clearstream Banking, S.A. or the Depository Trust Company (“DTC”) system. J.P. Morgan Securities plc, as the billing and delivering bank for the Tender Offer (in such capacity, the “Billing and Delivering Bank”), will consolidate all Tender Orders and accept Old Notes for purchase pursuant to the terms and conditions in the Tender Offer Memorandum on behalf of Türkiye, subject to proration at Türkiye’s sole discretion and other terms and conditions as described in the Tender Offer Memorandum, on Thursday, 26 September 2024 or as soon as possible thereafter. Failure to deliver Old Notes on time may result, in Türkiye’s sole discretion, in any of the following: (i) the cancellation of a holder’s tender and the holder becoming liable for any damages resulting from that failure, and/or (ii) the delivery of a buy-in notice for the purchase of such Old Notes, executed in accordance with customary brokerage practices for corporate fixed income securities, and/or (iii) in the case of Preferred Tenders, the cancellation of a holder’s tender and the holder remaining obligated to purchase its allocation of New Notes in respect of its related Indication of Interest.

Tender Orders for any series of Old Notes may be subject to proration at Türkiye’s sole discretion. To the extent proration occurs for any series of Old Notes, the Billing and Delivering Bank will accept Old Notes with appropriate adjustments to avoid the purchase of Old Notes in principal amounts other than Permitted Tender Amounts.

All Old Notes that are tendered pursuant to Tender Orders and are accepted by Türkiye will be purchased on behalf of Türkiye by the Billing and Delivering Bank directly or, if the tendering holder does not have an account with the Billing and Delivering Bank, through the Dealer Manager with which such holder placed a Tender Order, or through the broker, dealer, commercial bank, trust company, other financial institution, or other custodian that has an account with a Dealer Manager, with which such holder placed a Tender Order. There is no letter of transmittal for the Tender Offer. Old Notes held through DTC must be delivered for settlement no later than 8:00 p.m., London time, on the Tender Offer Settlement Date. If a holder holds Old Notes through Euroclear or Clearstream, the latest process it can use to deliver its Old Notes is the overnight

process, one day prior to the Tender Offer Settlement Date; holders may not use the optional daylight process. Holders will not have withdrawal rights with respect to any tenders of Old Notes in the Tender Offer. Old Notes accepted for purchase will be settled on a delivery versus payment basis in accordance with customary brokerage practices for corporate fixed income securities.

Türkiye plans, but is not required to, issue and sell New Notes to holders who validly tender their Old Notes pursuant to the Tender Offer and place firm orders for New Notes in the New Notes Offering during the Preferred Tender Period (as well as investors that are not participating in the Tender Offer). If Türkiye determines to issue and sell New Notes to such holders, the scheduled settlement date for the New Notes Offering is expected to occur on 3 October 2024.

The Tender Offer is subject to Türkiye’s right, at its sole discretion and subject to applicable law, to extend, terminate, withdraw, or amend the Tender Offer at any time. Türkiye reserves the right, in its sole discretion, not to accept tenders for any reason.
