On February 9, 2026, Antero Resources Corporation (the "Company") issued a conditional notice of full redemption (the "Notice") with respect to its 7.625% senior notes due 2029 (the "Notes"). The Company gave holders of the Notes notice that, subject to the satisfaction of the conditions precedent stated in the Notice, the Company will redeem all of the Notes outstanding on February 24, 2026 (the "Redemption Date") at a redemption price of 101.271% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the Redemption Date. As of February 9, 2026, there was $365,353,000 aggregate principal amount of Notes outstanding.

As permitted by the terms of the Notes, the Notice and the redemption of the Notes are conditioned upon the satisfaction of the conditions precedent of (i) the closing of the Company's divestiture of substantially all of its Utica Shale oil and gas assets located in Ohio (the "Ohio Utica Shale divestiture") and (ii) the Company's board of directors not having resolved that the redemption is no longer advisable and in the best interests of the Company. In the Company's discretion, the Redemption Date may be delayed until such time as any or all of the conditions have been satisfied. There can be no assurance that the redemption of the Notes will be consummated.
