& CHIEF OPERATING OFFICER

CHARLES A. EBETINO, JR. NAMED SENIOR VICE PRESIDENT
OF GLOBAL STRATEGY & CORPORATE DEVELOPMENT

          ST. LOUIS, September 14 — Patriot Coal Corporation (NYSE: PCX) today announced that it is realigning its senior management organization to bring additional talent and focus to all areas of its business, with particular emphasis on current mining operations, organic growth and global investment opportunities. Effective September 19, 2011, Bennett K. “Ben” Hatfield will join Patriot as Executive Vice President & Chief Operating Officer, reporting to President & Chief Executive Officer Richard M. Whiting. In this role, Hatfield will assume general management responsibility for all of Patriot’s mining and other operating activities and will be based in Charleston, West Virginia. At the same time, Patriot has named Charles A. “Chuck” Ebetino, Jr. as Senior Vice President — Global Strategy & Corporate Development, reporting to Whiting.

          “We are elated that Ben Hatfield has chosen to join forces with Patriot Coal to execute on our near-term opportunities and our long-term growth initiatives,” said Whiting. “I can think of no person in this industry whose capabilities are a better match with Patriot’s current challenges and future possibilities. Ben is a proven leader with a track record of major value creation in every step of his career.”

          Hatfield, 54, previously served for six years as President, Chief Executive Officer and Director of International Coal Group, a publicly-traded eastern U.S. coal producer, prior to the June 2011 sale of that company. Hatfield also has held a number of other key executive operating and commercial positions during a distinguished 30-plus year career in the coal industry, including President, Eastern Operations of Arch Coal, Inc., Executive Vice President and Chief Operating Officer of Massey Energy Company, and Executive Vice President & Chief Commercial Officer of Coastal Coal Company. He is a Licensed Professional Engineer with a B.S. in mining engineering from Virginia Polytechnic Institute and State University.

          Pursuant to the realignment, in his new role, Chuck Ebetino will assume responsibility for Patriot’s overall strategy development, merger and acquisition activities, resource management and various other strategic initiatives to enhance shareholder value. Ebetino has served as Senior Vice President & Chief Operating Officer of Patriot for the last year, and he previously held the position of Senior Vice President — Corporate Development since the establishment of Patriot in 2007. Ebetino has more than 30 years of operating and commercial experience in the coal and utility industries, including prior senior management roles at Peabody Energy and American Electric Power.

          “Patriot’s Board of Directors and senior team are very appreciative of Chuck Ebetino’s contributions to Patriot from Day-1 in 2007, but I would highlight the progress that Chuck has made with the planning and execution at our mining operations during the past twelve months as his most meaningful impact on the evolution of our company,” stated Whiting. “We are equally pleased to have Chuck spearhead our strategic business development activities going forward.”

          In addition to Messrs. Hatfield and Ebetino, the senior management team reporting to the CEO will be configured as follows:

	•		Mark N. Schroeder will continue as Senior Vice President & Chief Financial Officer
	•		Robert W. Bennett will continue as Senior Vice President & Chief Marketing Officer
	•		Joseph W. Bean will continue as Senior Vice President — Law & Administration and General Counsel.

          In closing, Whiting stated, “Each of my direct reports is uniquely qualified in his primary area of responsibility to create and execute Patriot’s plans for the creation of future shareholder value.”
