Southwestern Energy Company (NYSE: SWN) (the “Company”) today announced the extension of its previously announced cash tender offers (the “Tender Offers”) to purchase for cash up to $300,000,000 aggregate principal amount (the “Maximum Tender Amount”) of its 4.95% Senior Notes due 2025 (the “2025 Notes”) and its 7.75% Senior Notes due 2027 (the “2027 Notes” and, together with the 2025 Notes, the “Notes”), subject to the terms and conditions described in the Company’s Offer to Purchase dated November 23, 2021 (the “Offer to Purchase”).

The Tender Offers extended expiration date is 5:00 p.m., New York City time, on December 30, 2021 (the “Extended Expiration Date”).

The terms and conditions of the Tender Offers otherwise remain unchanged and are set forth in the Offer to Purchase.

According to information received from Global Bondholder Services Corporation, the Tender Agent and Information Agent for the Tender Offers, as of 5:00 p.m., New York City Time, on December 29, 2021, the Company received $401,547,000 aggregate principal amount of 2025 Notes validly tendered (and not validly withdrawn).

In addition, all of the 2025 Notes validly tendered at or prior to the Extended Expiration Date, including the 2025 Notes tendered as of 5:00 p.m. New York City Time on December 7, 2021 (the “Early Tender Time”) and any additional 2025 Notes validly tendered following the Early Tender Time, will be subject to proration based on the total principal amount of 2025 Notes validly tendered at or prior to the Extended Expiration Date.
