Denver, Colorado, May 15, 2024—Antero Resources Corporation (NYSE: AR) (“Antero Resources,” “Antero,” or the “Company”) today announced that it has received an investment grade credit rating of BBB- from S&P Global Ratings (“S&P”).

On May 15^th, 2024, S&P upgraded Antero’s corporate and issuer credit ratings to BBB- from BB+ with a stable outlook. The Company has maintained an investment grade credit rating from Fitch Ratings since September of 2022. With these two investment grade credit ratings, Antero expects a substantial reduction in letters of credit associated with its firm transportation portfolio and reduced interest expense.

Michael Kennedy, CFO of Antero Resources said, “Antero’s investment grade credit rating reinforces the strength of our company, driven by the success of our development program and commitment to debt reduction over the last several years. Since the start of our debt reduction program in the fourth quarter of 2019, we have reduced debt by more than $2 billion. This reduction, combined with our peer-leading capital efficiency and low breakeven costs, positions Antero Resources as the premier operator in Appalachia.”
