FOR IMMEDIATE RELEASE

ALLIANCE RESOURCE PARTNERS, L.P.

Reports Record Quarterly Revenues and EBITDA; Increases Quarterly Cash Distribution 3.7% to $1.0625 Per Unit; and Updates 2012 Guidance

TULSA, OKLAHOMA, July 27, 2012 – Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported financial results for the quarter ended June 30, 2012 (the “2012 Quarter”). Led by record coal sales volumes and pricing, revenues increased 15.7% to a record $529.9 million and EBITDA climbed 6.0% to a record $155.5 million, each as compared to the quarter ended June 30, 2011 (the “2011 Quarter”). Compared to the 2011 Quarter, net income declined 2.8% to $95.5 million, or $1.83 per basic and diluted limited partner unit due to anticipated increases in depreciation, depletion and amortization expense and the pass through of losses related to investments in White Oak Resources, LLC (“White Oak”). (For a definition of EBITDA and related reconciliations to comparable GAAP financial measures, please see the end of this release).

ARLP also announced that the Board of Directors of its managing general partner increased the cash distribution to unitholders for the 2012 Quarter to $1.0625 per unit (an annualized rate of $4.25 per unit), payable on August 14, 2012 to all unitholders of record as of the close of trading on August 7, 2012. The announced distribution represents a 15.2% increase over the cash distribution of $0.9225 per unit for the 2011 Quarter and a 3.7% increase over the cash distribution of $1.025 per unit for the first quarter of 2012 (the “Sequential Quarter”).

“ARLP’s operating strength, quality customer relationships and solid contract position allowed us to overcome challenging market conditions and deliver another quarter of excellent results to our unitholders,” said Joseph W. Craft III, President and Chief Executive Officer. “In addition to posting record EBITDA, sales volumes and revenue, our team’s accomplishments during the 2012 Quarter continued to strengthen ARLP’s long-term growth prospects. Operationally, we commenced longwall operations in mid-May at our Tunnel Ridge mine, completed the acquisition of the Onton No. 9 mine and continued to make progress at the Gibson South and White Oak mine development projects. On the sales side, we continued to execute ARLP’s strategy of securing long-term commitments for our production. To that end, we recently reached agreement for the sale of approximately 5.6 million tons over a six-year period. Since the beginning of the year, we have now made new coal sales commitments of 27 million tons, plus or minus 10% depending on customer nominations, for deliveries through 2018. Financially, we improved our liquidity by approximately $500 million by entering into new revolving credit and term loan facilities. These accomplishments continue to position ARLP for long-term growth giving our Board the confidence to again provide our unitholders with an attractive distribution increase for the seventeenth consecutive quarter.”

Consolidated Financial Results

Three Months Ended June 30, 2012 Compared to Three Months Ended June 30, 2011

Reflecting record sales volumes and pricing, coal sales revenues rose to $512.5 million in the 2012 Quarter, an increase of 15.8% compared to the 2011 Quarter. Improved price realizations, particularly in the Illinois Basin and Northern Appalachia, drove total average coal sales prices higher in the 2012 Quarter to a record $59.17 per ton sold, a 5.5% increase compared to the 2011 Quarter. Higher sales volumes in the Illinois Basin and Northern Appalachia, particularly at the Warrior and Tunnel Ridge mines and the newly acquired Onton mine, as well as increased brokerage sales volumes, pushed coal sales volumes up 9.8% in the 2012 Quarter to a record 8.7 million tons.

The increases at Warrior, Tunnel Ridge and Onton also contributed to higher coal production of 8.2 million tons in the 2012 Quarter, an increase of 8.6% compared to the 2011 Quarter. These higher coal sales and production volumes drove operating expenses in the 2012 Quarter higher to $334.6 million, an increase of 17.8% compared to the 2011 Quarter.

Outside coal purchases increased $10.3 million to $16.2 million in the 2012 Quarter compared to the 2011 Quarter, primarily as a result of increased brokerage coal sales volumes and higher cost per ton of coal purchased. General and administrative expenses increased $3.1 million to $16.1 million in the 2012 Quarter compared to the 2011 Quarter, primarily as a result of higher compensation-related expenses and other professional services. Depreciation, depletion and amortization increased to $13.0 million to $52.1 million in the 2012 Quarter compared to the 2011 Quarter, primarily as a result of the start-up of longwall production at the Tunnel Ridge mine, the addition of the Onton mine and capital expenditures related to infrastructure improvements at various other operations.

As anticipated, ARLP’s financial results for the 2012 Quarter were negatively impacted by losses related to White Oak’s development of its Mine No.1. Our preferred equity investment in White Oak requires ARLP to record substantially all of White Oak’s income and losses until we achieve our contractual preferred return. As a result, net equity in loss of affiliates in the 2012 Quarter primarily reflects the pass through of approximately $4.6 million of losses related to White Oak’s mine development activities.

Six Months Ended June 30, 2012 Compared to Six Months Ended June 30, 2011

For the six months ended June 30, 2012 (the “2012 Period”), increases at the River View and Tunnel Ridge mines and the acquisition of the Onton mine in the 2012 Quarter led to record production and sales volumes as tons produced climbed 6.0% and tons sold increased 6.8%, compared to the six months ended June 30, 2011 (the “2011 Period”). Higher coal sales volumes and increased average coal sales prices, which rose $2.08 per ton sold, combined to drive 2012 Period revenues to a record $973.5 million, an increase of 10.5% compared to the 2011 Period. Offsetting these increases, higher operating costs and depreciation, depletion and amortization,

and the pass through of losses related to the White Oak development project discussed above, as well as reduced sales into the metallurgical export markets during the 2012 Period led to lower EBITDA and net income. EBITDA for the 2012 Period was comparable to the 2011 Period, falling slightly to $287.0 million, while net income declined 7.8% to $178.4 million, or $3.36 per basic and diluted limited partner unit.

Regional Results and Analysis

Reflecting higher Illinois Basin, Northern Appalachia and brokerage sales volumes, ARLP sold a record 8.7 million tons of coal in the 2012 Quarter, an increase of 9.8% over the 2011 Quarter. Coal sales volumes in the Illinois Basin increased from the 2011 and Sequential Quarters, primarily as a result of strong sales and production performance from the Warrior mine and the addition of the Onton mine. In Central Appalachia, lower coal sales volumes compared to the 2011 Quarter reflect the loss of a production unit at the Pontiki mine in the third quarter of 2011 and, compared to the Sequential Quarter, the loss of a production unit during the 2012 Quarter at the MC Mining mine, each due to regulatory action. Coal sales volumes in Northern Appalachia

increased from the 2011 and Sequential Quarters reflecting the start-up of longwall production at the Tunnel Ridge mine in May 2012. Sequentially, Northern Appalachia also benefited from higher export sales as tons that had been deferred from the first quarter of 2012 were shipped from the Mettiki mining complex during the 2012 Quarter.

Total coal inventory declined by approximately 243,000 tons during the 2012 Quarter to approximately 822,000 tons. ARLP continues to anticipate coal inventories will trend lower throughout the balance of this year.

Compared to the 2011 Quarter, ARLP continued to benefit from improved contract pricing, particularly in the Illinois Basin and Northern Appalachia, as total average coal sales price increased 5.5% to $59.17 per ton sold in the 2012 Quarter. Sequentially, total coal sales prices increased 7.6% due primarily to the previously mentioned higher priced export shipments in the 2012 Quarter.

Total Segment Adjusted EBITDA Expense per ton in the 2012 Quarter increased 9.6% compared to the 2011 Quarter, reflecting the previously discussed increases in operating expenses. Compared to the Sequential Quarter, Segment Adjusted EBITDA Expense per ton in the 2012 Quarter was impacted by fewer work days due to traditional miner vacations in all of ARLP’s operating regions. In the Illinois Basin, lower coal recoveries at the River View mine, difficult mining conditions at the Dotiki mine related to its transition into the West Kentucky No. 13 coal seam and the addition of the Onton No. 9 mine, contributed to higher Segment Adjusted EBITDA Expense per ton in the 2012 Quarter. In Central Appalachia, the impact of the loss of a production unit at both the Pontiki and MC Mining mines due to regulatory action, offset in part by improved coal recoveries, contributed to higher Segment Adjusted EBITDA Expense per ton in the 2012 Quarter. In Northern Appalachia, higher Segment Adjusted EBITDA Expense per ton reflects increased cost per ton of coal purchased by the Mettiki complex, higher cost per ton of initial longwall production at the Tunnel Ridge mine, as well as the impact of difficult mining conditions at the Mountain View mine. (For a definition of Segment Adjusted EBITDA and Segment Adjusted EBITDA Expense per ton and related reconciliations to comparable GAAP financial measures, please see the end of this release).

Outlook

Commenting on ARLP’s outlook Mr. Craft continued, “The first half of 2012 has been an extremely challenging market environment for the coal industry as the U.S. experienced significant year-over-year declines in coal-fired electricity generation causing a steep reduction in domestic coal demand. Recently, hotter weather patterns, rising natural gas prices, strong export thermal sales and supply reductions by other coal producers gives us hope that better days are ahead for the coal markets. We still are concerned, however, about a weak U.S. economy and the direction of the global economy. This weakness and uncertainty has impacted demand and pricing for our metallurgical coal sales for the remainder of this year. We expect to ship the last 70,000 tons on our high-priced export contract in July. We are in negotiations to continue shipping into the export metallurgical market but cannot predict if, or when, shipments will resume. On a positive note, at Tunnel Ridge our production was 300,000 tons in the 2012 Quarter and is expected to grow to 900,000 tons in the third quarter of 2012 and reach 1.2 million tons in the fourth quarter of this year. With our strong balance sheet and contract portfolio, as well as the increased production from Tunnel Ridge, ARLP is well positioned to manage through these near-term challenges and we expect to deliver record EBITDA results consistent with previous guidance.”

Reflecting results to date and adjusting for current coal sales and production mix expectations, ARLP currently anticipates full-year 2012 results near the lower end of its previous guidance ranges for production volumes of 35.2 to 36.4 million tons, sales volumes of 35.6 to 36.9 million tons and revenues, excluding transportation revenues, of $2.06 to $2.12 billion.

Based on current expectations, ARLP is essentially fully priced and committed for its anticipated 2012 coal sales volumes. ARLP has also secured coal sales commitments for approximately 36.1 million tons, 29.3 million tons and 22.8 million tons in 2013, 2014 and 2015, respectively, of which approximately 1.0 million tons in 2013 and 2.9 million tons in both 2014 and 2015 remain open to market pricing.

For 2012, ARLP is anticipating full-year results near the midpoint of its previous guidance ranges for consolidated EBITDA of $585.0 to $615.0 million and net income of $345.0 to $385.0 million. Consolidated estimates for 2012 continue to reflect the negative effects of ARLP’s White Oak investments, which are now estimated in a range of $15.0 to $20.0 million for EBITDA and $12.0 to $17.0 million for net income. (For a definition of EBITDA and related reconciliations to comparable GAAP financial measures, please see the end of this release.)

ARLP continues to anticipate total 2012 capital expenditures in a range of $565.0 to $610.0 million, including approximately $95.0 to $110.0 million for reserve acquisitions and construction of surface facilities related to the White Oak mine development project. In addition, ARLP now expects to fund approximately $75.0 to $95.0 million of its preferred equity investment commitment to White Oak during 2012.

Reconciliation of GAAP “Net Income” to non-GAAP “EBITDA” and non-GAAP “Distributable Cash Flow” (in thousands).

EBITDA is defined as net income before net interest expense, income taxes and depreciation, depletion and amortization. EBITDA is used as a supplemental financial measure by our management and by external users of our financial statements such as investors, commercial banks, research analysts and others, to assess:

Distributable cash flow (“DCF”) is defined as EBITDA excluding interest expense (before capitalized interest), interest income, income taxes and estimated maintenance capital expenditures. DCF is used as a supplemental financial measure by our management and by external users of our financial statements, such as investors, commercial banks, research analysts and others, to assess:

EBITDA and DCF should not be considered as alternatives to net income, income from operations, cash flows from operating activities or any other measure of financial performance presented in accordance with generally accepted accounting principles. EBITDA and DCF are not intended to represent cash flow and do not represent the measure of cash available for distribution. Our method of computing EBITDA and DCF may not be the same method used to compute similar measures reported by other companies, and EBITDA and DCF may be computed differently by us in different contexts (i.e. public reporting versus computation under financing agreements).

Reconciliation of GAAP “Operating Expenses” to non-GAAP “Segment Adjusted EBITDA Expense per ton” and Reconciliation of non-GAAP “EBITDA” to “Segment Adjusted EBITDA” (in thousands, except per ton data).

Segment Adjusted EBITDA Expense per ton includes operating expenses, outside coal purchases and other income divided by tons sold. Transportation expenses are excluded as these expenses are passed through to our customers and, consequently, we do not realize any margin on transportation revenues. Segment Adjusted EBITDA Expense is used as a supplemental financial measure by our management to assess the operating performance of our segments. Segment Adjusted EBITDA Expense is a key component of EBITDA in addition to coal sales and other sales and operating revenues. The exclusion of corporate general and administrative expenses from Segment Adjusted EBITDA Expense allows management to focus solely on the evaluation of segment operating performance as it primarily relates to our operating expenses. Outside coal purchases are included in Segment Adjusted EBITDA Expense because tons sold and coal sales include sales from outside coal purchases.

Segment Adjusted EBITDA is defined as net income before net interest expense, income taxes, depreciation, depletion and amortization and general and administrative expenses.
