First Quarter 2013 Financial Results

Partnership achieves further operating improvements;

Nears comprehensive resolution to credit facility maturity to enhance financial flexibility

COLUMBUS, Ohio, May 15, 2013 – Oxford Resource Partners, LP (NYSE: OXF) (the “Partnership” or “Oxford”) today announced first quarter 2013 financial results.

Adjusted EBITDA¹ was $9.0 million for the first quarter of 2013 compared to $11.0 million for the first quarter of 2012. Adjusted EBITDA declined due to the planned lower sales volume from the Partnership’s Illinois Basin operations. Cash margin per ton increased 7.9 percent to $6.40 in the first quarter of 2013 from $5.93 in the first quarter of 2012. This was driven by a 3.3 percent increase in coal sales revenue per ton to $50.65, partially offset by a 2.7 percent increase in cash cost of coal sales per ton to $44.25 as a result of the planned lower production from the Illinois Basin operations and increased purchased coal volume.

Net loss for the first quarter of 2013 was $6.3 million compared to a net loss of $15.7 million for the first quarter of 2012. Net loss for the first quarter of 2013 included $0.1 million of impairment and restructuring expenses and a $0.5 million loss on disposal of assets. Net loss for the first quarter of 2012 included $8.4 million in impairment and restructuring expenses and a $1.1 million loss on disposal of assets. Excluding impairment and restructuring expenses and losses on disposal of assets, Adjusted Net Loss² would have been $5.7 million for the first quarter of 2013 compared to $6.2 million for the first quarter of 2012.

“I am pleased to report that the year is off to a good start with first quarter Adjusted EBITDA performance showing a $1.0 million improvement over the fourth quarter,” said Oxford’s President and Chief Executive Officer Charles C. Ungurean. “We have been working diligently to address the upcoming credit facility maturity and expect to announce a comprehensive resolution within the next few weeks. With this increased financial flexibility, we will be better positioned to participate in a coal market rebound. We are encouraged by the recent decline in utility stockpiles and higher natural gas prices in our region, both of which should drive increasing demand in our market. Our recent actions to improve cash margins set the stage for us to generate further profitability improvement on higher future coal volumes.”

Business Update

Oxford’s projected sales volume is almost fully committed and priced for 2013, underscoring the strength of its long-term customer relationships and its strategic importance in its core region. For 2014, projected sales volume is 79 percent committed (with 47 percent of the projected sales volume priced and 32 percent of the projected sales volume unpriced).

As a leading low-cost producer of thermal coal and the largest producer of surface mined coal in Ohio, Oxford is focused on its core Northern Appalachian operations. Continued rationalization of the Partnership’s Illinois Basin operations has allowed for the transfer of excess equipment to the Northern Appalachian mines, which has reduced capital expenditure spending. Based on current market conditions, the Partnership expects to idle production at its Illinois Basin operations and conclude its restructuring activities by the end of 2013.

Liquidity

As of March 31, 2013, the Partnership had $5.3 million of cash with no available borrowing capacity on its credit facility. In February 2013, the Partnership enhanced liquidity with the receipt of a settlement of $2.1 million from a purchase coal supplier to settle a contract dispute. The Partnership continues to pursue the sale of excess Illinois Basin equipment which had a net book value of $6.1 million at the end of the first quarter.

Credit Facility

The Partnership’s current revolving credit facility matures in July 2013. Accordingly, as previously reported, the Partnership has been engaged in active negotiations addressing this upcoming maturity and expects to announce a comprehensive resolution within the next few weeks.

Because this resolution is not yet finalized and the Partnership is now in default of certain financial covenants, the borrowings under the credit facility of $147.5 million are presented as a current liability in its March 31, 2013 consolidated financial statements. The Partnership has obtained a forbearance agreement from the lenders under the credit facility pursuant to which the lenders have agreed to forbear from seeking any remedies for such defaults for a period of 30 days.

2013 Guidance

The Partnership provides the following updated guidance for 2013 based on its current industry outlook:

The Partnership expects to produce between 6.0 million tons and 6.5 million tons and sell between 6.4 million tons and 6.9 million tons of thermal coal. The average selling price is projected to be $50.50 per ton to $52.50 per ton, with an anticipated average cost of $42.85 per ton to $44.85 per ton.

Adjusted EBITDA is expected to be in the range of $45 million to $50 million.

The Partnership anticipates capital expenditures of between $22 million and $25 million.

¹ Adjusted EBITDA is a non-GAAP financial measure used by management to gauge operating performance. We define Adjusted EBITDA as net income or loss before deducting interest, income taxes, depreciation, depletion, amortization, impairment and restructuring expenses, loss on disposal of assets, below-market coal sales contract amortization, non-cash equity-based compensation expense, non-cash changes in mine reclamation obligations, and certain non-recurring items. Although Adjusted EBITDA is not a measure of financial performance calculated in accordance with GAAP, we believe it is useful to management and others, such as investors and lenders, in evaluating our financial performance without regard to financing methods, capital structure or income taxes; our ability to generate cash sufficient to pay interest on our indebtedness, make distributions and fund capital expenditures; and our compliance with certain credit facility financial covenants. Because not all companies calculate Adjusted EBITDA the same way, our calculation may not be comparable to similarly titled measures of other companies.

We define Adjusted Net Loss as net income or loss before deducting impairment and restructuring expenses and loss on disposal of assets. Although Adjusted Net Loss is not a measure of financial performance calculated in accordance with GAAP, we believe it is useful to management and others, such as investors and lenders, in evaluating our financial performance without regard to significant items which are primarily non-cash and our restructuring efforts which are not typical operating activities.

³ Per ton amounts are calculated by dividing the related amount on the financial statements by the number of tons sold. Although per ton amounts are not measures of performance calculated in accordance with GAAP, we believe they are useful to management and others, such as investors and lenders, in evaluating performance because they are widely used in the coal industry as a measure to evaluate a company's sales performance or control over costs. Because not all companies calculate these measures the same way, our calculations may not be comparable to similarly titled measures of other companies.
