“Considering continued difficult market conditions, Alpha delivered solid results during the first quarter of 2013, maintaining a sharp focus on operational execution and building on our recent strategic restructuring,” said Kevin Crutchfield, chairman and CEO. “Our safety performance was outstanding, and stronger than expected shipment volumes and lower unit costs, driven in part by the success of our recent cost control initiatives, helped offset lower realizations on metallurgical coal, resulting in first quarter adjusted EBITDA of $117 million.”

“The restructuring plan we announced in September of 2012 is largely behind us, and we've taken many necessary steps to align our business with current market conditions from both an operational and capital spending standpoint. Going forward, we will continue to assess the need for further adjustments to our portfolio and marketing strategy where necessary to position ourselves for both sides of the commodity cycle.”

Alpha's workforce delivered excellent safety performance during the first quarter of 2013. Compared to the fourth quarter of 2012, Alpha's incident rate improved 15 percent sequentially and days lost improved by 24 percent. In addition, the Republic Energy Surface Mine was awarded the Bart B. Lay, Jr. Milestones of Safety award as the most outstanding surface mine in the state of West Virginia. “We applaud the successful efforts of our workforce, and we will continue to focus on continually improving our safety performance and advancing the objective of 'Running Right' at all of our operations,” said Mr. Crutchfield.

Across all production basins, Alpha demonstrated strong operational execution in the first three months of 2013. On an annualized basis shipment volumes during the quarter were pacing ahead of the midpoint of prior full-year guidance for both Eastern and Western thermal coals. Due primarily to strong shipment volumes and the benefits of our restructuring efforts, Alpha's cost of coal sales per ton were also better than the midpoint of previous guidance. In particular, very strong production at the Pennsylvania longwall mines drove unit costs lower across all Eastern tons. While Eastern unit costs were favorable in the first quarter, per ton costs are expected to normalize to the $69 to $73 as longwall production levels vary, and production cutbacks implemented thus far impact shipment volumes and product mix in future quarters.

As a result of the strong operational execution, timing of scheduled interest payments on senior notes and a disciplined approach to capital expenditures in the first quarter, Alpha generated $21 million of free cash flow (non-GAAP measure defined as cash flow from operations of $65 million, less capital expenditures of $44 million). This solid financial performance enabled Alpha to maintain liquidity of approximately $2.1 billion as of March 31, 2013, including approximately $1 billion in cash, cash equivalents and marketable securities.

Financial Performance

• Total revenues in the first quarter of 2013 were $1.3 billion compared with $1.9 billion in the first quarter of 2012, and coal revenues were $1.1 billion, down from $1.6 billion in the year-ago period. The decreases in total revenues and coal revenues were primarily attributable to lower average realizations for metallurgical and Eastern steam coal and lower steam coal shipment volumes. Freight and handling revenues and other revenues were $157 million and $36 million, respectively, during

the first quarter of 2013 versus $209 million and $86 million, respectively, in first quarter of 2012.

During the first quarter of 2013, metallurgical coal shipments were 5.1 million tons, compared with 4.9 million tons in both the first quarter of 2012 and the prior quarter (the fourth quarter of 2012). Alpha shipped 10.0 million tons of Powder River Basin (PRB) coal during the quarter, compared with 11.8 million tons in the year-ago period and 11.6 million tons in the prior quarter. Eastern steam coal shipments were 7.9 million tons, compared with 11.5 million tons in the year-ago period and 9.4 million tons in the prior quarter. The average per ton realization on metallurgical coal shipments in the first quarter was $103.28, down from $145.51 in the first quarter last year and $121.27 in the prior quarter. Average per ton realization for PRB shipments rose slightly to $13.03, compared with $12.95 in the first quarter last year and $13.00 in the prior quarter. The per ton average realization for Eastern steam coal shipments was $61.90, compared with $67.48 in the year-ago period and $64.55 in the prior quarter.

• Total costs and expenses during the first quarter of 2013 were $1.5 billion, compared with $2.0 billion in the first quarter of 2012. Cost of coal sales was $1.0 billion, compared with $1.4 billion in the year-ago period. The cost of coal sales in the East averaged $69.52 per ton, compared with Eastern cost of coal sales per ton of $77.25 in the first quarter last year. Excluding $0.19 per ton of merger-related expenses, the adjusted cost of coal sales in the East averaged $69.33 per ton, compared with $76.00 in the first quarter last year which excluded $1.11 of merger-related expense and a $0.14 impact of the write-off of weather-related property damage. The decrease in adjusted Eastern cost of coal sales per ton during the first quarter of 2013 primarily reflects the impact of strong production and unit cost performance from the Pennsylvania longwall mines, Alpha's restructuring and cost control measures, the related shift in mix with the relatively lower-cost longwall mines contributing a larger percentage of overall Eastern production, and lower variable costs (royalties and taxes) driven by lower average per ton realizations on both metallurgical and thermal coal. The cost of coal sales per ton for Alpha Coal West's PRB mines was $10.02 during the first quarter of 2013, compared with cost of coal sales per ton of $10.96 in the first quarter of 2012, partially due to mining a higher proportion of coal owned in fee for which is there is no production royalty expense.

• Selling, general and administrative (SG&A) expense in the first quarter of 2013 was $44 million, compared with selling, general and administrative expense of $65 million in the first quarter of 2012 which included $6 million of merger-related expenses. Depreciation, depletion and amortization (DD&A) decreased to $239 million during the first quarter of 2013 from $286 million in the year-ago period primarily due to lower cost depletion resulting from lower thermal coal production volumes, and lower cost depletion rates per ton at certain mines as a result of long-lived asset impairments recorded in 2012. The benefit from amortization of acquired intangibles, net, fell to $5 million, compared with a benefit of $36 million last year, primarily due to the completion of shipments under many of the coal supply agreements acquired from Massey.

• Alpha recorded a net loss of $111 million, or $0.50 per diluted share, during the first quarter of 2013, compared with a net loss of $29 million, or $0.13 per diluted share, during the first quarter of 2012. The year-over-year increase in Alpha's net loss is primarily attributable to lower per ton realizations on metallurgical and Eastern thermal coal and lower shipment volumes of Eastern and Western thermal coal, partly offset by lower cost of coal sales per ton, and lower SG&A and DD&A expenses.

Excluding the items described in our “Reconciliation of Adjusted Net Loss to Net Loss,” the adjusted net loss was $104 million, or $0.47 per diluted share, compared with an adjusted net loss of $58 million, or $0.27 per diluted share, in the first quarter of 2012.

• EBITDA was $105 million in the first quarter of 2013, compared with $222 million in the year ago period. Excluding the items described in the “Reconciliation of EBITDA and Adjusted EBITDA to Net Loss,” adjusted EBITDA was $117 million in the first quarter of 2013, compared with $210 million in the first quarter of 2012.

Liquidity and Capital Resources

Cash provided by operating activities for the quarter ended March 31, 2013 was $65 million, compared with $167 million for the first quarter of 2012. Capital expenditures for the first quarter of 2013 were $44 million, compared with $126 million in the first quarter of 2012.

As of the end of the first quarter of 2013, Alpha maintained total liquidity above $2 billion, with total liquidity as of March 31, 2013 of $2.06 billion, consisting of cash, cash equivalents and marketable securities of $1.03 billion, plus $1.03 billion available under the company's secured credit facility and accounts receivable securitization facility. Total long-term debt, including the current portion of long-term debt as of March 31, 2013 was relatively unchanged from December 31, 2012 at $3.4 billion.

Market Overview

Nationwide utility inventories stood at an estimated 174 million tons at the end of March 2013. While this level is below the 2012 peak of 214 million tons, it is still elevated relative to the 5-year historical average. Elevated utility inventories and the gradual, secular shift away from coal-fired generation continue to drive weakness in the domestic thermal coal market; however, differences are clearly emerging between the various production basins in the United States. In the PRB, the annualized production in the first quarter of 2013 was approximately 380 million tons, compared to production capacity in the PRB of nearly 500 million tons. Even with the forecast of a modest recovery in nationwide coal consumption of 40 million to 50 million tons in 2013 as a result of sustained natural gas prices above the $4 level, barring any unforeseen supply or transportation disruption, it is unrealistic to expect the latent capacity in the PRB to be absorbed in the near-term, suggesting a period of relatively stagnant market conditions for PRB coal.

In the eastern United States, inventories of NAPP thermal coal at utilities are approximately equal to the 5-year historical average providing a fairly balanced supply-demand landscape, and opportunities exist for producers to contract additional volumes with utility customers. However, despite the relatively healthy inventory levels, the ability of electrical generators to switch to other low cost coals, such as from the Illinois Basin, has created a somewhat stagnant pricing environment. Inventories of CAPP thermal coals have roughly doubled from their historical average in terms of days of burn to approximately 137 days as of the end of March 2013. This inventory situation has been driven by a reduction in utility consumption owing to a host of factors, including fuel switching in favor of gas due to the relatively high cost of CAPP thermal coal, coal-fired plant retirements which are disproportionately impacting the regions served by CAPP thermal coal, and encroachment of other lower cost coals, such as from the Illinois Basin. We believe a significant portion of the decreased consumption of CAPP thermal coal is a structural phenomenon, and Alpha has accordingly substantially reduced its production of CAPP thermal coal through its recent restructuring activities. Furthermore, at today's seaborne thermal coal prices in the Atlantic, most eastern U.S. production is uneconomic, adding to the difficult supply/demand environment and general market weakness.

As a key objective of its repositioning plan, Alpha is primarily focused on supporting and augmenting its global metallurgical coal business, which is the third largest in the world. The second quarter Asian benchmark price announced in March 2013 increased $7 to $172 per metric tonne on an FOBT basis. However, recent transactions have been reported at levels $10 to $12 below the benchmark, likely due to the perception of slowing growth in Chinese steel production, which accounts for approximately 60 percent of global blast furnace steel production, along with continuing economic weakness in Europe. Chinese steel production is projected to grow between 4 percent and 5 percent in 2013, and any uptick in Chinese imports should lead to improved conditions for the seaborne met market. Steel production in Europe during the first two months of 2013 was down approximately 5 percent year-over-year, reducing demand for metallurgical coals in the Atlantic basin and weighing on the prices of U.S. exports. The supply/demand picture for lower quality met coals remains imbalanced, and these coals are being discounted, pressuring margins which may trigger additional production cutbacks. In general, conditions in the metallurgical coal markets remain challenging. However, met coal is a highly cyclical and volatile product, with the highest qualities found in relatively few locations around the globe. In the intermediate to long run, the world is expected to require increasing volumes of met coal, and when market conditions improve, we believe Alpha is well-positioned to benefit from its leadership position in met coal reserves, met coal production and export terminal capacity.

2013 Outlook

Alpha now expects to ship between 83 and 93 million tons during 2013, including 19 to 22 million tons of Eastern metallurgical coal, 27 to 31 million tons of Eastern steam coal, and 37 to 40 million tons of Western steam coal out of the PRB. As of April 19, 2013, 73 percent of the midpoint of anticipated 2013 metallurgical coal shipments were committed and priced at an average per ton realization of $103.93. Based on the midpoint of guidance, 100 percent of anticipated Eastern steam coal shipments were committed and priced at an average per ton realization of $61.96; and 99 percent of the midpoint of anticipated PRB shipments were committed and priced at an average per ton realization of $12.74. The Company's 2013 cost of coal sales is expected to range between $69 and $73 per ton in the East and between $10 and $11 per ton in the West. Selling, general and administrative expenses are anticipated to range from $140 million to $160 million for 2013. Interest expense and DD&A expense are anticipated to be in the ranges of $230 million to $240 million and $875 million to $975 million, respectively, and capital expenditures for 2013 are expected to fall within the range of $300 million to $350 million.

FINANCIAL TABLES FOLLOW

Use of Non-GAAP Measures

In addition to the results prepared in accordance with generally accepted accounting principles in the United States (GAAP) provided throughout this press release, Alpha has presented the following non-GAAP financial measures, which management uses to gauge operating performance: EBITDA, adjusted EBITDA, adjusted net loss, adjusted diluted loss per common share, adjusted cost of coal sales per ton, adjusted coal margin per ton, and adjusted weighted average coal margin per ton. These non-GAAP financial measures exclude various items detailed in the attached “Reconciliation of EBITDA and Adjusted EBITDA to Net Loss” and “Reconciliation of Adjusted Net Loss to Net Loss.” Alpha has also presented free cash flow, which is a non-GAAP measure defined as net cash provided by operating activities, less capital expenditures and annual lease-by-application bonus bid payments.

The definition of these non-GAAP measures may be changed periodically by management to adjust for significant items important to an understanding of operating trends.  These measures are not intended to replace financial performance measures determined in accordance with GAAP. Rather, they are presented as supplemental measures of the Company's performance that management finds useful in assessing the company's financial performance and believes are useful to securities analysts, investors and others in assessing the Company's performance over time.  Moreover, these measures are not calculated identically by all companies and therefore may not be comparable to similarly titled measures used by other companies.
