Permian Resources Corporation ("Permian Resources" or the "Company") (NYSE:PR) today announced that it is now rated investment grade by both S&P Global Ratings ("S&P") and Fitch Ratings ("Fitch"), following today's upgrade from S&P and the Company's initial investment grade rating from Fitch in July 2025.

On March 17, 2026, S&P upgraded Permian Resources' corporate and issuer credit ratings to BBB- from BB+ with a stable outlook. This follows the Company's initial investment grade credit rating from Fitch, which upgraded the Company to BBB- with a stable outlook in July 2025. With investment grade ratings from both S&P and Fitch, Permian Resources expects reduced interest expense and improved liquidity, among other benefits.

"We appreciate Fitch and S&P's acknowledgment of the strength of our business and our balance sheet," said James Walter, Co-CEO of Permian Resources. "Over the past ten years, we have run our business with an investment grade mindset, pairing high-quality assets with a fortress balance sheet to create outsized shareholder value through commodity cycles. Achieving investment grade status further enhances our ability to continue our track record of driving free cash flow and shareholder returns going forward."
