Alliance Resource Partners, L.P. Increases Quarterly Cash Distribution 1.9% to $0.6625 Per Unit and Updates 2015 Guidance

Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported financial and operating results for the quarter ended March 31, 2015 (the "2015 Quarter"). Total revenues climbed to $560.4 million, an increase of 3.4% compared to the quarter ended March 31, 2014 (the "2014 Quarter") reflecting higher other sales and operating revenues. Increased revenues and production contributed to higher EBITDA, which rose $1.8 million to $192.2 million for the 2015 Quarter. Net income for the 2015 Quarter decreased 8.1% to $106.5 million, or $0.92 per basic and diluted limited partner unit compared to the 2014 Quarter primarily due to increased depreciation, depletion and amortization expense. (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 (the "Board") increased the cash distribution to unitholders for the 2015 Quarter to $0.6625 per unit (an annualized rate of $2.65 per unit), payable on May 15, 2015 to all unitholders of record as of the close of trading on May 8, 2015. The announced distribution represents an 8.4% increase over the cash distribution of $0.61125 per unit for the 2014 Quarter and a 1.9% increase over the cash distribution of $0.65 per unit for the quarter ended December 31, 2014 (the "Sequential Quarter"). The comparative distributions per unit, as well as net income per basic and diluted limited partner unit, reflected for the 2014 Quarter in this press release have been adjusted for the two-for-one unit split completed on June 16, 2014.

"ARLP continued its strong operating and financial performance in the first quarter of 2015, reporting increases to coal production volumes, revenues and EBITDA," said Joseph W. Craft III, President and Chief Executive Officer. "Contributing to these results, our Tunnel Ridge mine continued to experience higher productivity, performing above expectations to drive production in our Appalachian region higher in the 2015 Quarter by almost 13% compared to the 2014 Quarter. All operations performed well during the 2015 Quarter and our teams posted the best safety performance in ARLP’s history. We are also beginning to see the benefits of our investment in White Oak as revenues and EBITDA from this project increased by $14.7 million and $9.3 million, respectively, compared to the 2014 Quarter."

Mr. Craft continued, "Our financial performance for the 2015 Quarter was impacted by delayed shipments on contracted tons due to frigid February weather and high waters on the Ohio River that disrupted barge transportation. Inventory at our mines grew by more than 1.0 million tons during the 2015 Quarter to 2.4 million tons, causing us to reduce our production at several operations to offset the inventory build. We expect to ship approximately 800,000 tons above our production in the upcoming quarter and continue to work off the inventory over the balance of the year. Based on ARLP’s quarterly results and confidence in our future performance, the Board announced today an increase in unitholder distributions for the twenty-eighth consecutive quarter."

Consolidated Financial Results

Three Months Ended March 31, 2015 Compared to Three Months Ended March 31, 2014

For the 2015 Quarter, revenues increased to $560.4 million compared to $542.0 million for the 2014 Quarter, primarily due to higher surface facility services and coal royalties related to ARLP’s participation in the White Oak Mine No. 1, which added approximately $14.7 million of additional other sales and operating revenues in the 2015 Quarter. This increase in revenues was partially offset by lower coal sales revenues as a result of lower average coal sales price which decreased slightly to $54.49 per ton sold. Although impacted by weather-related disruptions, total coal sales volumes in the 2015 Quarter remained consistent with the 2014 Quarter, while coal production volumes increased 2.4% to 10.5 million tons in the 2015 Quarter.

Compared to the 2014 Quarter, operating expenses increased in the 2015 Quarter by 3.8% to $334.4 million. This increase was primarily the result of increased coal sales and production volumes from our Gibson South and Tunnel Ridge mines as well as higher labor-related expenses at the Illinois Basin operations. These increases were partially offset by lower sales at our Warrior mine as it continues to transition to a new mining area, our Gibson North mine due to shift reductions in response to market conditions and an inventory build at our River View mine. Segment Adjusted EBITDA Expense per ton increased 3.8% to $35.21 in the 2015 Quarter compared to the 2014 Quarter primarily due to tons sold from high-cost beginning inventory at various operations and lower recoveries at our Warrior and Gibson North mines.

Depreciation, depletion and amortization increased $11.4 million to $78.3 million in the 2015 Quarter compared to the 2014 Quarter, due to the previously announced reduction of the economic mine life at our Hopkins mine, which is expected to close in early 2016, production at the Gibson South mine, which began in April 2014, amortization of coal supply agreements acquired in December 2014 and capital expenditures related to infrastructure investments at various operations.

The previously discussed increase in revenues from White Oak in the 2015 Quarter more than offset the pass through of related net equity in loss of affiliates, resulting in higher Segment Adjusted EBITDA for the White Oak Segment of $5.3 million compared to a loss of $4.1 million in the 2014 Quarter. Total net equity in loss of affiliates increased to $9.7 million for the 2015 Quarter, compared to a loss of $6.2 million for the 2014 Quarter, primarily due to higher expenses reflecting White Oak’s continued ramp up of longwall operations following the commencement of operations in late 2014.

Regional Results and Analysis

Increased coal sales volumes from the Tunnel Ridge and Mettiki longwall operations drove sales tons for the 2015 Quarter higher by 17.9% in Appalachia, compared to the 2014 Quarter. In the Illinois Basin, coal sales volumes decreased in the 2015 Quarter compared to both the 2014 and Sequential Quarters primarily due to timing of shipments partially offset by increased sales volumes from our new Gibson South mine.

Compared to the Sequential Quarter, weather-related transportation disruptions negatively impacted coal shipments in the 2015 Quarter, particularly at our Warrior, Gibson North, River View and Tunnel Ridge mines. Delayed shipments pushed total coal inventory to approximately 2.4 million tons during the 2015 Quarter. Coal shipments have recently improved, allowing ARLP to begin reducing coal stockpiles at our operations. We currently anticipate coal inventories will return to more normalized levels by year end.

As anticipated, for the 2015 Quarter, ARLP's total coal sales price of $54.49 per ton sold decreased compared to both the 2014 and Sequential Quarters. Decreased coal sales prices in Appalachia primarily reflect lower average prices at our MC Mining and Tunnel Ridge mines due to current market conditions. Coal sales prices also declined in the Illinois Basin, primarily due to lower coal sales prices at our Gibson North and Onton mines.

Total Segment Adjusted EBITDA Expense per ton decreased 1.3% in the 2015 Quarter compared to the Sequential Quarter. In the Illinois Basin, Segment Adjusted EBITDA Expense per ton improved by 6.4% in the 2015 Quarter compared to the Sequential Quarter primarily due to additional production days reflecting seasonal differences, higher production at the Gibson South mine and increased productivity at the River View and Dotiki mines. Sequentially, Segment Adjusted EBITDA Expense per ton in Appalachia increased 8.8% primarily as a result of lower production at our Tunnel Ridge mine due to a longwall move in the 2015 Quarter. Compared to the 2014 Quarter, higher Total Segment Adjusted EBITDA Expense per ton primarily reflects a 3.6% increase in the Illinois Basin as a result of decreased production and higher inventory costs at our Warrior, Gibson North and Onton mines as well as increased medical expense at all mines in the region. Partially offsetting this increase, Segment Adjusted EBITDA Expense per ton in Appalachia declined by 3.1% compared to the 2014 Quarter primarily due to improved productivity and lower benefits costs at our Mettiki mine in addition to increased production at Tunnel Ridge reflecting fewer longwall move days in the 2015 Quarter, partially offset by increased materials and supplies and maintenance costs at Tunnel Ridge.

As discussed above, total Segment Adjusted EBITDA compared to the 2014 and Sequential Quarters benefited from the ramp-up of longwall production from the White Oak mine. ARLP’s Segment Adjusted EBITDA attributable to its investments in White Oak increased by $9.3 million and $1.2 million compared to the 2014 and Sequential Quarters, respectively.

Guidance Outlook

Commenting on ARLP’s current outlook for the rest of the year, Mr. Craft said, "The coal industry outlook remains challenged as demand for U.S. thermal coal has dropped further than expected this year and the supply response has been slow to occur. Relying on our sales contract position, strong balance sheet and low cost operations, we remain confident we are well positioned to achieve our financial goals for the year, including growing cash flow again in 2015.

To adjust to current market conditions we have decided to reduce our production further in 2015, which will save the Partnerships some capital expenditures. We expect the reduced production will have minimal impact on our cost per ton sold. We anticipate tons sold would be reduced by a similar amount, or approximately 700,000 tons at the midpoint of the prior guidance range."

Based on results to date and current estimates, in 2015 ARLP is now anticipating coal production in a range of 40.2 to 41.2 million tons and sales volumes in a range of 40.75 to 42.65 million tons. ARLP has committed and priced approximately 96% of its anticipated coal sales in 2015 and has also secured coal sales and price commitments for approximately 28.9 million tons, 12.8 million tons and 9.6 million tons in 2016, 2017 and 2018, respectively.

ARLP currently anticipates 2015 revenues, excluding transportation revenues, in a range of $2.35 to $2.41 billion. ARLP’s 2015 per ton estimates and guidance ranges for EBITDA of $765.0 to $825.0 million and net income of $395.0 to $455.0 million remain unchanged from our initial outlook for the year. (For a definition of EBITDA and related reconciliation to the most comparable GAAP financial measure, please see the end of this release.)

ARLP is lowering anticipated total capital expenditures during 2015 to a range of $270.0 to $300.0 million due to mine plan changes at various operations in the Illinois Basin. In addition to these anticipated capital expenditures, ARLP now expects to fund approximately $20.0 to $25.0 million of its investment commitment to purchase oil and gas mineral interests, of which $8.0 million was funded in the 2015 Quarter. ARLP also funded $10.3 million of its preferred equity investment commitment to White Oak in the 2015 Quarter and does not anticipate funding any further preferred equity investments.

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

EBITDA is defined as net income (prior to the allocation of noncontrolling interest) 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:

• the financial performance of our assets without regard to financing methods, capital structure or historical cost basis;
• the ability of our assets to generate cash sufficient to pay interest costs and support our indebtedness;
• our operating performance and return on investment as compared to those of other companies in the coal energy sector, without regard to financing or capital structures; and
• the viability of acquisitions and capital expenditure projects and the overall rates of return on alternative investment opportunities.

Distributable cash flow ("DCF") is defined as EBITDA excluding equity in income or loss of affiliates, 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:

• the cash flows generated by our assets (prior to the establishment of any retained cash reserves by the general partner) to fund the cash distributions we expect to pay to unitholders;
• our success in providing a cash return on investment and whether or not the Partnership is generating cash flow at a level that can sustain or support an increase in its quarterly distribution rates;
• the yield of our units, which is a quantitative standard used through the investment community with respect to publicly-traded partnerships as the value of a unit is generally determined by a unit’s yield (which in turn is based on the amount of cash distributions the entity pays to a unitholder).

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, or EBITDA and DCF may be computed differently by us in different contexts (i.e. public reporting versus computation under financing agreements).

⁽¹⁾ Our maintenance capital expenditures, as defined under the terms of our partnership agreement, are those capital expenditures required to maintain, over the long-term, the operating capacity of our capital assets. We estimate maintenance capital expenditures on an annual basis based upon a five-year planning horizon. For the 2015 planning horizon, average annual estimated maintenance capital expenditures are assumed to be $5.55 per produced ton compared to the estimated $5.90 per produced ton in 2014. Our actual maintenance capital expenditures vary depending on various factors, including maintenance schedules and timing of capital projects, among others. We annually disclose our actual maintenance capital expenditures in our Form 10-K filed with the Securities and Exchange Commission.

Reconciliation of GAAP "Operating Expenses" to non-GAAP "Segment Adjusted EBITDA Expense per ton" and Reconciliation of non-GAAP "EBITDA" to "Segment Adjusted EBITDA per ton" (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 per ton is defined as net income (prior to the allocation of noncontrolling interest) before net interest expense, income taxes, depreciation, depletion and amortization and general and administrative expenses divided by tons sold. Segment Adjusted EBITDA removes the impact of general and administrative expenses from EBITDA (discussed above) to allow management to focus solely on the evaluation of segment operating performance.
