FOR IMMEDIATE RELEASE

ALLIANCE RESOURCE PARTNERS, L.P.

Reports Increased Coal Sales and Production Volumes, Revenues, Net Income and EBITDA; Raises Quarterly Unitholder Distribution by 2.0% to $1.175 Per Unit

TULSA, OKLAHOMA, October 28, 2013 — Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported increased financial and operating results for the quarter ended September 30, 2013 (the “2013 Quarter”).  Led by higher coal sales volumes in the 2013 Quarter, revenues climbed to $537.2 million, an increase of 5.0% compared to the quarter ended September 30, 2012 (the “2012 Quarter”).  Increased revenues and coal sales volumes contributed to higher net income, which jumped 44.1% to $87.2 million, or $1.50 per basic and diluted limited partner unit, and EBITDA, which rose 24.3% to $158.5 million.  Comparative results were also impacted by a non-cash asset impairment charge of $19.0 million at the Pontiki mining complex in the 2012 Quarter.  (For a definition of EBITDA, Adjusted EBITDA and related reconciliations to the most comparable GAAP financial measure, 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 2013 Quarter to $1.175 per unit (an annualized rate of $4.70 per unit), payable on November 14, 2013 to all unitholders of record as of the close of trading on November 7, 2013.  The announced distribution represents an 8.3% increase over the cash distribution of $1.085 per unit for the 2012 Quarter and a 2.0% increase over the cash distribution of $1.1525 per unit for the 2013 second quarter (the “Sequential Quarter”).

“Posting increases to coal sales and production volumes, revenues, EBITDA and net income, ARLP once again delivered growth in the 2013 Quarter,” said Joseph W. Craft III, President and Chief Executive Officer.  “The high performance of our teams and continued focus on expanding ARLP’s presence in the Illinois Basin and Northern Appalachian markets has allowed us to succeed in the current challenging market environment. Our solid contract portfolio and ongoing growth projects also leave ARLP well positioned for the future.  We are pleased to share these successes with our unitholders, as the Board elected to increase quarterly cash distributions for the twenty-second consecutive quarter.”

Consolidated Financial Results

Three Months Ended September 30, 2013 Compared to Three Months Ended September 30, 2012

During the 2013 Quarter, increased volumes at the Tunnel Ridge longwall operation and strong performance at the River View, Gibson North and Dotiki mines, drove coal sales volumes up 6.7% to 9.5 million tons and production volumes higher by 7.6% to 9.7 million tons, both as compared to the 2012 Quarter.  Volume growth more than offset lower average coal sales prices, leading to increased revenues, EBITDA and net income in the 2013 Quarter.

Compared to the 2012 Quarter, increased coal sales and production volumes resulted in increased sales-related expenses, materials and supplies expenses, labor-related expenses and maintenance costs, which combined to push operating expenses in the 2013 Quarter higher by 2.2% to $346.0 million.  Coal brokerage and purchasing activity declined in the 2013 Quarter, resulting in a $3.8 million reduction in outside coal purchases.  On a per ton basis, increased coal sales volumes contributed to lower Segment Adjusted EBITDA Expense per ton in the 2013 Quarter, which declined 5.3% compared to the 2012 Quarter.

General and administrative expenses increased $1.3 million to $14.9 million in the 2013 Quarter compared to the 2012 Quarter, primarily as a result of higher incentive compensation expenses. Depreciation, depletion and amortization increased $6.3 million to $66.1 million in the 2013 Quarter compared to the 2012 Quarter, primarily as a result of the increased production volumes mentioned above, as well as capital expenditures related to production expansion and infrastructure investments at various operations.

As anticipated, ARLP’s financial results for both the 2013 and 2012 Quarters were negatively impacted by losses related to White Oak’s development of its Mine No.1.  Since our equity investment in White Oak entitles ARLP to receive substantially all distributions from White Oak until we achieve our contractual preferred return, ARLP currently reflects substantially all of White Oak’s income and losses in its financial results.  Reported net equity in loss of affiliates of $6.0 million for the 2013 Quarter and $2.8 million for the 2012 Quarter was primarily due to the allocation of losses related to White Oak’s mine development activities.

Nine Months Ended September 30, 2013 Compared to Nine Months Ended September 30, 2012

For the nine months ended September 30, 2013 (the “2013 Period”), increases at the River View, Gibson North and Tunnel Ridge mines and production from the Onton mine, which we acquired in April 2012, led to record production and sales volumes as tons produced climbed 15.3% and tons sold increased 14.3% compared to the nine months ended September 30, 2012 (the “2012 Period”).  Higher coal sales volumes drove 2013 Period revenues to a record $1.6 billion, an increase of 10.4% compared to the 2012 Period.  The increase in coal sales volumes was partially offset by lower average coal sales prices, which decreased to $54.95 per ton sold in the 2013 Period compared to $56.77 per ton sold for the 2012 Period, primarily due to ARLP electing not to participate in the weak metallurgical export markets in the 2013 Period.  For the 2013 Period, EBITDA increased 23.0% to a record $510.0 million and net income rose 23.1% to $294.2 million, or $5.41 of net income per basic and diluted limited partner unit.

Regional Results and Analysis

(1)         Sales price per ton is defined as total coal sales divided by total tons sold.

(2)         For definitions of Segment Adjusted EBITDA Expense per ton and Segment Adjusted EBITDA and related reconciliations to comparable GAAP financial measures, please see the end of this release.

(3)         Total includes White Oak, other, corporate and eliminations.

On the strength of higher Illinois Basin coal sales volumes, ARLP sold 9.5 million tons of coal in the 2013 Quarter, an increase of 6.7% over the 2012 Quarter.  Coal sales volumes in the Illinois Basin increased 9.8% over the 2012 Quarter as strong sales and production performance at the River View, Dotiki and Gibson North mines more than offset the impact of a temporary halt of production operations at the Onton mine due to adverse geological conditions.  Coal sales volumes declined in Central Appalachia primarily as a result of timing differences in customer shipments during the 2013 Quarter compared to the 2012 Quarter.  In Northern Appalachia, coal sales volumes decreased due to the timing of shipments from Mettiki in the 2013 Quarter compared to the 2012 Quarter, offset in part by increased coal sales from the continued ramp-up of longwall production at the Tunnel Ridge mine.  Compared to the Sequential Quarter, Northern Appalachia coal sales declined due to a longwall move and lower coal recoveries at the Tunnel Ridge mine during the 2013 Quarter.

ARLP’s coal inventory of approximately 998,000 tons at the end of the 2013 Quarter was comparable to ending inventory of approximately 977,000 tons for the 2012 Quarter.

As anticipated, compared to the 2012 Quarter, ARLP’s total coal sales price per ton sold was lower due to the previously mentioned lack of metallurgical coal sales during the 2013 Quarter.  Coal

sales price per ton in the 2013 Quarter decreased slightly from the Sequential Quarter, primarily due to sales mix in the Illinois Basin and timing of shipments in Central Appalachia.

Total Segment Adjusted EBITDA Expense per ton in the 2013 Quarter decreased 5.3% compared to the 2012 Quarter, primarily as a result of increased production and sales volumes, as well as reduced outside coal purchases and lower inventory costs in all regions.  In the Illinois Basin, Segment Adjusted EBITDA Expense per ton improved in the 2013 Quarter compared to the 2012 Quarter primarily due to the previously discussed strong performance at the River View Dotiki and Gibson North mines and lower workers’ compensation expense.  These improvements were offset in part by the impact of the temporary halt of production operations at the Onton mine, which is also reflected in the sequentially higher Segment Adjusted EBITDA per ton.  In Central Appalachia, Segment Adjusted EBITDA Expense per ton improved in the 2013 Quarter due to lower inventory costs and reduced repair costs.  Compared to the 2012 Quarter, Segment Adjusted EBITDA Expense per ton in Northern Appalachia benefited from the continued ramp-up of longwall production at the Tunnel Ridge mine and reduced outside coal purchases, partially offset by higher employee benefit costs, particularly medical expenses, at Mettiki.  Compared to the Sequential Quarter, Segment Adjusted EBITDA Expense per ton increased due to a longwall move and lower recoveries at the Tunnel Ridge mine during the 2013 Quarter.

Commenting on ARLP’s outlook Mr. Craft continued, “ARLP remains on track to deliver its thirteenth consecutive year of record financial and operating results in 2013.  As we look forward, ARLP is poised for more growth in 2014.  Our production will increase next year as Tunnel Ridge is currently expected to produce approximately 5.5 million tons in 2014.  In addition, our new Gibson South mine is scheduled to begin initial production in the third quarter of 2014 and longwall production at the White Oak mine development project is anticipated to begin in the second half of next year.  We also continue to enhance ARLP’s already strong contract portfolio.  During the 2013 Quarter, we secured new coal sales commitments for delivery of approximately 3.3 million tons through 2016.”

Due to the unanticipated disruption to production operations at Onton, which reduced ARLP’s expected EBITDA in the 2013 Quarter by approximately $13.3 million, ARLP currently anticipates 2013 full year results near the lower end of its previous guidance ranges for coal production, 39.3 to 39.6 million tons; coal sales volumes, 38.6 to 39.6 million tons; revenues, excluding transportation revenues, $2.165 to $2.225 billion; EBITDA, $675.0 to $695.0 million; and net income, $375.0 to $395.0 million.  The 2013 ranges for both EBITDA and net income reflect the pass through of approximately $20.0 to $30.0 million of expected losses related to ARLP’s investments in White Oak.  (For a definition of EBITDA and related reconciliation to the most comparable GAAP financial measure, please see the end of this release.)

ARLP remains fully priced and committed for its anticipated 2013 coal sales volumes.  For 2014, ARLP currently has approximately 32.6 million tons priced and committed.  In addition, ARLP currently has commitments for approximately 26.6 million tons and 20.5 million tons in 2015 and 2016, respectively, of which approximately 2.5 million tons in 2015 and 3.3 million tons in 2016 remain open to market pricing.

ARLP continues to anticipate 2013 total capital expenditures in a range of $370.0 to $400.0 million, which includes expenditures for mine expansion and infrastructure projects, maintenance capital, continued development of the Gibson South mine, and reserve acquisitions and construction of surface facilities related to the White Oak mine development project.  In addition,

ARLP has funded $47.5 million of preferred equity investments to White Oak in 2013, bringing its total equity investment to date to $150 million.  Based on currently anticipated equity capital contributions by its partners, ARLP does not expect to make further equity investments in White Oak this year.

Reconciliation of GAAP “Net Income” to non-GAAP “EBITDA” and “Adjusted 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 and Adjusted EBITDA is EBITDA modified to reflect significant non-recurring items that may not reflect the trend of future results.  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.

We believe Adjusted EBITDA is a useful measure for investors because it further demonstrates the performance of our assets without regard to non-recurring charges.

Distributable cash flow (“DCF”) is defined as Adjusted EBITDA excluding equity in 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, Adjusted 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, Adjusted 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, Adjusted 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).

(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 2013 planning horizon, average annual estimated maintenance capital expenditures are assumed to be $5.70 per produced ton compared to the estimated $5.50 per produced ton in 2012.  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” (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, general and administrative expenses and asset impairment charge.
