PATRIOT COAL ANNOUNCES RESULTS
FOR THE QUARTER ENDED JUNE 30, 2011

Summary:

	•		Record second quarter EBITDA of $70.2 million, up 73% from a year ago
	•		Record revenue of $632.2 million and revenue per ton of $77.05 for second quarter
	•		Cash flow from operating activities of $81.3 million in the second quarter, more than twice the previous quarterly record
	•		Production underway at new Gateway Eagle and Workman Branch met coal mines
	•		Nearly 7 million tons of additional thermal coal booked for export through 2014

     ST. LOUIS, July 26 — Patriot Coal Corporation (NYSE: PCX) today reported its financial results for the quarter ended June 30, 2011. For the 2011 second quarter, the Company reported record revenues of $632.2 million and record EBITDA of $70.2 million. Revenues and EBITDA for the year-ago quarter were $539.0 million and $40.6 million, respectively. For the six months ended June 30, 2011, the Company reported revenues of $1.2 billion and EBITDA of $118.8 million. Revenues and EBITDA for the first half of 2010 were $1.0 billion and $85.8 million, respectively.

     During the second quarter, the Company recorded an asset retirement obligation of $24.0 million for the planned treatment of certain selenium discharges at the Hobet surface mine, in connection with the submission of a remediation plan related to a previous court ruling. As a result of this charge, the Company reported a net loss of $12.4 million and net loss per share of $0.14 for the 2011 second quarter.

     “Our improved performance this quarter highlights the potential of Patriot’s existing operations and the results of our detailed planning and execution,” noted Patriot President and Chief Executive Officer Richard M. Whiting. “We are nearing a major turning point in the life of our company.”

     “Looking to 2012 and beyond, we expect to achieve even stronger operating results as we benefit from our “Met Build-Out” project. In recent months, we started production at two new met mines — the Gateway Eagle mine in the Rocklick complex and the Workman Branch mine in the Wells complex. And we have made significant progress constructing the entry slope at Kanawha Eagle’s Peerless mine, where we expect to begin production late this year,” continued Whiting. “Further, as 2012 comes more clearly into view, we will see a positive impact from the re-pricing to market levels of 3.5 million tons of Illinois Basin coal currently sold under a legacy customer contract. Our team is actively managing the sale of these tons, with close to 80 percent of the volume already sold for 2012.”

     “Turning to the markets, we are encouraged by the strength of the global thermal coal market. Since our April update, we booked nearly 7 million thermal tons for export through 2014, including sales from each of our basins. Over half of this volume will be sourced from the Illinois Basin, including tons previously sold under the legacy contract,” stated Whiting. “On the met side, since our April update we contracted an additional 400,000 tons for 2011 delivery. With the cycle of annual contracting largely completed for 2011, we do not expect the next wave of met contracting to occur before the fourth quarter.”

     “Our cash flow from operating activities topped $80 million this quarter, more than twice the previous quarterly high of $39 million. After covering capital expenditures and a litigation settlement, we generated free cash flow of more than $20 million,” added Patriot Senior Vice President and Chief Financial Officer Mark N. Schroeder. “This is a clear indication of our future earnings power and cash flow trends, and our ability to continue to grow our business.”

Financial Overview

     Commenting further on the second quarter, Schroeder noted, “We are pleased with our record revenues and record EBITDA achieved this quarter. This marks our third consecutive increase in quarterly EBITDA, led by solid operating performance at our mines, along with higher selling prices. These stronger results were consistent with our operating and financial plans.”

     “Costs per ton in both of our segments increased this quarter and for the first six months were at the upper end of our annual guidance. A number of factors impacted our costs this quarter, including the new metallurgical mines coming on-line, met tons being a larger portion of our total sales mix, higher sales-related costs, and the idling of the Panther longwall for about two weeks for an equipment component upgrade,” continued Schroeder. “While the richer product mix has pressured our per-ton costs, our focus remains on expanding our bottom line through higher-margin business opportunities.”

     Revenues in the 2011 second quarter were $632.2 million, compared with $539.0 million in the prior year quarter. Higher revenues in the 2011 quarter compared with the prior year resulted from higher selling prices in 2011, which increased almost $11.00, or 16 percent, over a year ago.

     Sales in the second quarter totaled 8.1 million tons, including 6.1 million tons of thermal and 2.0 million tons of metallurgical coal. This compares with 6.2 million tons of thermal and 1.9 million tons of metallurgical coal sold in the year-ago quarter.

     EBITDA in the 2011 second quarter was $70.2 million, compared with $40.6 million in the same quarter of 2010. Higher EBITDA was driven by higher average selling prices. The 2011 second quarter EBITDA included gains on reserve-related transactions of $9.4 million, compared with $17.8 million in the 2010 second quarter.

Credit and Capital

     As of June 30, 2011, the Company had available liquidity of more than $480 million, with a cash balance of $263 million and no borrowings on its revolving credit facility or its receivables securitization program.

     Capital expenditures totaled $40.7 million in the 2011 second quarter. For 2011, the Company expects capital expenditures to be near $175 million, as Patriot expands its metallurgical coal production capability.

     During the quarter, the Company paid $14.8 million in settlement of litigation in connection with a lawsuit filed prior to the 2007 spin-off. The settlement did not result in any impact to the Company’s statement of operations during the quarter, as Patriot received certain mineral reserves while assuming related liabilities from the plaintiff as part of the settlement.

Safety and Environmental

     As a result of the Company’s comprehensive safety program, in the first half of 2011 Patriot achieved an accident incidence rate of 2.86 per 200,000 hours worked, nearly a 20 percent improvement compared with the 2010 year. Additionally, during the quarter three Patriot operations in West Virginia received state-wide Joseph A. Holmes Safety Awards, and Fredrick Collins, Jr., Patriot’s Senior Safety Manager, was recognized as a Coal Safety Leader by the Holmes Safety Association.

     In recognition of outstanding reclamation, Patriot operations also received two regional Appalachian Regional Reforestation Initiative (ARRI) Awards, and the Company’s Guyan surface mine in the Logan County complex subsequently won the highest ARRI award, presented to one reclamation project from the submissions of seven different states.

Market Overview

     Forecasts continue to point to the sustainability of coal market globalization. Global seaborne demand for metallurgical coal is expected to increase more than 50 percent from about 250 million metric tonnes in 2010 to nearly 400 million tonnes by 2020. On the thermal side, global seaborne demand is expected to increase more than 30 percent from 2010 to 2020, to almost 1 billion tonnes. With supply constraints worldwide, Patriot believes U.S. metallurgical and thermal coal will increasingly be shipped overseas to satisfy the robust global demand. Eastern U.S. metallurgical and thermal coals, in particular, are well-positioned to participate in these growing export markets.

     The Company believes the metallurgical coal market will remain tight. Patriot’s response to these tight met markets is to continue its Met Build-Out project, increasing met production to at least 11 million tons by 2013. The Company is on track with this expansion plan, which includes acquiring equipment, finalizing permits, and hiring supervisors and hourly employees. The manageable size of each mine within the Met Build-Out is a distinct advantage, as it allows the Company to methodically increase production in line with sales commitments, and to benefit from its existing operational footprint.

     In thermal markets, the Company expects to see continued opportunities for exports, as Asian markets build more coal-fueled power plants, putting more demand on global supply. The physical access of U.S. coals to the European thermal market, coupled with numerous coal quality alternatives, should make the U.S. a major ongoing participant in the increasingly global marketplace.

     Patriot expects U.S. coal exports to approximate 100 million tons in 2011. The Company plans to export approximately 25 percent of its 2011 production, with exports anticipated to expand to more than 10 million tons, or 30 percent, in 2012.

Outlook

     For the year 2011, the Company anticipates sales volume of 31 to 32 million tons, including metallurgical coal sales of at least 8 million tons. For the Appalachia segment, the Company expects cost per ton in the third quarter to be in the mid-$70’s, declining to the low-$70’s in the fourth quarter. The full-year cost is expected to average just over $70 per ton, as the met percentage increases to approximately 35 percent by year-end, from 30 percent at the beginning of 2011. For the Illinois Basin segment, Patriot expects cost per ton for the 2011 year to average $42 to $44.

     Higher cost per ton will result from the new met mines beginning production in 2011, higher sales-related costs, and increased costs related to an anticipated new labor agreement with the UMWA. Additionally, the third quarter will be impacted by longwall moves at both Federal and Panther, downtime for miner vacations and repairs performed during the vacation periods.

     Average selling prices of currently priced tons for the remainder of 2011 and for 2012 are as follows:

		Second Half 2011								2012
(Tons in millions)		Tons				Price per ton				Tons				Price per ton
Appalachia — thermal			7.9			$	60				11.4			$	64
Illinois Basin — thermal			3.6			$	41				5.2			$	49
Appalachia — met			4.0			$	151				1.0			$	151
Total			15.5								17.6

     The increase in priced 2012 met business compared with the first quarter earnings release includes newly booked Panther-type tons at prices averaging $150 per ton, coupled with the impact of changes in the timing of 2011 and 2012 met deliveries.

     Priced thermal business includes 4.1 million tons for the second half of 2011 and 4.7 million tons for 2012 related to legacy contracts priced significantly below the current market. The Company has around 0.5 million tons of coal remaining to be priced for 2011 delivery.

Adjusted EBITDA, also referred to as EBITDA, is defined as net loss before deducting interest income and expense, income taxes, asset retirement obligation expense, depreciation, depletion and amortization, restructuring and impairment charge and sales contract accretion. We have included information concerning EBITDA because we believe that in our industry such information is a relevant measurement of a company’s operating financial performance. Because EBITDA is not calculated identically by all companies, our calculation may not be comparable to similarly titled measures of other companies. The table above reflects the Company’s calculation of EBITDA.
