______________________________________

⁽¹⁾ As of the date of this press release.

As of 5:00 p.m., New York City time, on March 17, 2026 (the "Early Tender Date"), according to information provided by D.F. King & Co., Inc., the Tender Agent and the Information Agent for the Tender Offer, the aggregate principal amount of the Notes set forth in the table above under "Principal Amount Tendered" had been validly tendered and not validly withdrawn. Withdrawal rights for the Notes expired at 5:00 p.m., New York City time, on March 17, 2026 (the "Withdrawal Date"), and have not been extended. Notes validly tendered may not be withdrawn after the Withdrawal Date, except as may be required by law.

The Company has amended the Maximum Tender Amount to accept up to $1,000,000,000 principal amount of Notes validly tendered and not validly withdrawn at or prior to the Early Tender Date. Holders who validly tendered their Notes at or prior to the Early Tender Date will receive the "Total Consideration" of $1,031.75 for each $1,000 principal amount of Notes accepted for purchase. The Total Consideration includes the "Early Tender Premium" of $50 for each $1,000 principal amount of Notes. The Company has also amended the terms of the Tender Offer to extend the Total Consideration, which includes the Early Tender Premium, to all Notes validly tendered after the Early Tender Date, but at or prior to the Expiration Date, and not validly withdrawn.

In addition to the Total Consideration, holders who validly tender and do not validly withdraw Notes and whose Notes are accepted for purchase will receive accrued and unpaid interest, up to, but not including, the applicable settlement date. The settlement date with respect to all Notes validly tendered at or prior to the Early Tender Date and not validly withdrawn and accepted for purchase is March 19, 2026 (the "Early Settlement Date").

Since the Tender Offer is not fully subscribed as of the Early Settlement Date, the settlement date with respect to all Notes validly tendered after the Early Tender Date, but at or prior to the Expiration Date, and not validly withdrawn, is expected to be on the second business day after the Expiration Date, or promptly thereafter (such date, as the same may be extended, the "Final Settlement Date"). The Final Settlement Date is currently expected to be April 3, 2026.

Notes validly tendered at or prior to the Early Tender Date are being accepted for purchase with priority over the Notes validly tendered after the Early Tender Date, but at or prior to the Expiration Date.

Acceptance of Notes validly tendered after the Early Tender Date may be subject to proration if the aggregate principal amount of the Notes validly tendered and not validly withdrawn is greater than the Maximum Tender Amount. SM Energy reserves the right, but is under no obligation, to further increase the Maximum Tender Amount at any time, subject to compliance with applicable law.

The Tender Offer will expire at 5:00 p.m., New York City time, on April 1, 2026, unless extended (such date and time, as the same may be extended, the "Expiration Date").

The completion of the Tender Offer is subject to a number of conditions that are set forth in the Offer to Purchase. The Tender Offer is not conditioned on any minimum amount of Notes being tendered.

The terms and conditions of the Tender Offer, including SM Energy's obligation to accept the Notes tendered and pay the purchase price therefor, are set forth in the Offer to Purchase. SM Energy may, at its own discretion, amend, extend or, subject to certain conditions, terminate the Tender Offer.
