PRESS RELEASE

ALLIANCE RESOURCE PARTNERS, L.P.

Reports Increased Financial and Operating Results; Raises Quarterly Cash Distribution to $0.525 Per Unit; and Updates Guidance

TULSA, OKLAHOMA, October 29, 2018 —  Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported financial and operating results for the quarter ended September 30, 2018 (the "2018 Quarter").  Led by higher revenues and investment income, net income attributable to ARLP increased 20.3% to $73.7 million for the 2018 Quarter, compared to $61.3 million for the three months ended September 30, 2017 (the "2017 Quarter").  Strong coal sales volumes in the 2018 Quarter drove total revenues higher to $497.8 million, an increase of 9.8% compared to the 2017 Quarter.  Net income attributable to ARLP per basic and diluted limited partner unit was $0.55 for the 2018 Quarter compared to $0.52 for the 2017 Quarter as higher net income was partially offset by increased weighted-average common units outstanding due to the issuance of additional common units pursuant to the July 2017 Exchange Transaction.  EBITDA also increased 8.3% in the 2018 Quarter to $154.0 million compared to $142.2 million in the 2017 Quarter.  (For a definition of EBITDA and related reconciliation to comparable GAAP financial measures, please see the end of this release.  For actual and pro forma earnings per basic and diluted limited partner unit reflecting the Simplification and Exchange Transactions as if the transactions had occurred on January 1, 2017, please see the end of this release.)

As previously announced on October 26, 2018, the Board of Directors of ARLP's general partner (the "Board") increased the cash distribution to unitholders for the 2018 Quarter to $0.525  per unit (an annualized rate of $2.10 per unit), payable on November 14, 2018 to all unitholders of record as of the close of trading on November 7, 2018.  The announced distribution represents a 4.0% increase over the cash distribution of $0.505 per unit for the 2017 Quarter and a 1.0% increase over the cash distribution of $0.52 per unit for the quarter ended June 30, 2018 (the "Sequential Quarter").

"ARLP delivered strong results for the 2018 Quarter, posting increases to all major operating and financial metrics," said Joseph W. Craft III, President and Chief Executive Officer.  "In addition to delivering solid performance, we also continued to position ARLP for long term success.  Taking advantage of positive fundamentals in the domestic and international coal markets, our operations increased production compared to the 2017 and Sequential Quarters and our marketing team strengthened ARLP’s coal contract book by securing new commitments for approximately 11.1 million tons to be delivered through 2021, including 4.9 million tons for export through 2019."

Mr. Craft added, "ARLP remained focused on executing its strategic objectives of investing in our business for long-term cash flow growth and returning cash to unitholders.  During the 2018 Quarter, we brought the second continuous mining unit into operation at our Gibson North mine and added the tenth continuous mining unit at our River View mine.  These additions, along with additional efforts outlined below, will allow ARLP to increase future production to meet developing market opportunities.  ARLP also continued to focus on returning cash to unitholders, first by the Board again electing to increase distributions to unitholders and, second, by executing on the recently authorized unit repurchase program.  Under this program, through the end of the 2018 Quarter, ARLP has repurchased approximately 1.1 million units for approximately $21.1 million in open market transactions." 

Consolidated Financial Results

Three Months Ended September 30, 2018 Compared to Three Months Ended September 30, 2017

Coal sales revenues for the 2018 Quarter increased 5.8%, compared to the 2017 Quarter, to $460.3 million due to increased coal sales volumes and prices.  Coal sales volumes of 10.1 million tons were 4.4% higher than the 2017 Quarter, primarily reflecting increased export volumes from our Gibson South mine and increased volumes resulting from the resumption of operations in the Sequential Quarter at our Gibson North mine.  Coal sales prices increased 1.3% to $45.71 per ton sold for the 2018 Quarter, compared to $45.12 per ton sold for the 2017 Quarter, primarily as a result of higher price realizations from our Appalachian mines.

Compared to the 2017 Quarter, operating expenses increased 4.7% to $308.4 million, primarily as a result of increased coal sales volumes.  Segment Adjusted EBITDA Expense per ton remained comparable to the 2017 Quarter, increasing slightly to $30.70 per ton in the 2018 Quarter. (For a definition of Segment Adjusted EBITDA Expense per ton and related reconciliation to comparable GAAP financial measures, please see the end of this release.)

Investment income from our oil and gas minerals and gas compression services equity investments contributed income of $10.0 million in the 2018 Quarter, an increase of $3.4 million compared to the 2017 Quarter, primarily due to increased earnings from our investments in oil and gas minerals.

Nine Months Ended September 30, 2018 Compared to Nine Months Ended September 30, 2017

Net income attributable to ARLP increased $86.4 million to $315.8 million for the nine months ended September 30, 2018 (the "2018 Period"), compared to $229.4 million for the nine months ended September 30, 2017 (the "2017 Period"). The increase was due to higher revenues and investment income, a net gain on settlement of litigation and a debt extinguishment loss in the 2017 Period, partially offset by higher operating expenses and depreciation, depletion and amortization.

Total revenues increased by 12.0% to $1.47 billion for the 2018 Period compared to the 2017 Period due primarily to increased coal sales volumes.  For the 2018 Period, strong performances at River View and our Gibson County Complex mines, which includes the resumption of operations at Gibson North in the 2018 Period, drove total coal sales volumes up 8.1% to 30.0 million tons and production volumes higher by 6.6% to 30.1 million tons compared to the 2017 Period.   

Increased coal sales volumes in the 2018 Period also led operating expenses higher to $896.8 million, an increase of 12.9% compared to the 2017 Period.  Segment Adjusted EBITDA Expense per ton also increased 4.9% to $30.06 primarily as a result of difficult mining conditions encountered at several mines, higher roof support expense and additional longwall move days in the 2018 Period.  Compared to the 2017 Period, depreciation, depletion and amortization increased 5.2% to $204.2 million in the 2018 Period as a result of the previously discussed increase in coal sales volumes. 

On March 9, 2018, ARLP finalized an agreement with a customer and certain of its affiliates to settle litigation we initiated in 2015.  The agreement provided for a $93.0 million cash payment to ARLP, future conditional coal supply commitments, continued export trans-loading capacity for our Appalachian mines and the acquisition of 57 million tons of additional coal reserves near our Tunnel Ridge operation.  A settlement gain of $80.0 million was recorded in the 2018 Period reflecting the cash payment received net of certain costs associated with the gain.

Increased earnings from our investments in oil and gas mineral interests led equity method investment income higher by $4.1 million in the 2018 Period compared to the 2017 Period.  Equity securities income increased $8.8 million to $11.6 million in the 2018 Period compared to the 2017 Period due to increased distributions of preferred interests from our investment in gas compression services, which investment was made during the 2017 Quarter.  Comparative results between the 2018 and 2017 Periods were also impacted by the $8.1 million debt extinguishment loss incurred related to ARLP's early repayment of its Series B Senior Notes in May 2017.    

Regional Results and Analysis

Total coal sales volumes increased 4.4% in the 2018 Quarter to 10.1 million tons compared to the 2017 Quarter, due to higher coal sales volumes, particularly export volumes, from both the Illinois

Basin and Appalachian regions.  In the Illinois Basin, the resumption of operations at our Gibson North mine in the Sequential Quarter and improved sales at our Gibson South mine drove tons sold higher by 5.4% to 7.2 million tons in the 2018 Quarter compared to the 2017 Quarter.  Sequentially, a longwall move at the Hamilton mine during the 2018 Quarter and increased sales from inventory in the Sequential Quarter caused coal sales volumes to decline by 7.3% in the Illinois Basin.  In Appalachia, coal sales volumes increased 6.0% compared to the Sequential Quarter primarily due to improved recoveries and fewer longwall move days at our Tunnel Ridge mine in the 2018 Quarter.  ARLP ended the 2018 Quarter with total coal inventory of 0.9 million tons, a reduction of approximately 0.6 million tons and 0.2 million tons compared to the end of the 2017 and Sequential Quarters, respectively.

Coal sales price realizations increased 8.8% per ton sold in Appalachia in the 2018 Quarter compared to the 2017 Quarter, primarily due to increased export sales prices for metallurgical coal at our Mettiki mine and improved prices at our MC Mining and Tunnel Ridge mines. 

In the Illinois Basin, Segment Adjusted EBITDA Expense per ton decreased 2.1% compared to the 2017 Quarter primarily due to improved recoveries and increased longwall shifts at our Hamilton mine.  Segment Adjusted EBITDA Expense per ton in Appalachia increased 6.3% compared to the 2017 Quarter reflecting lower yields at our MC Mining mine and a longwall move at the Tunnel Ridge mine during the 2018 Quarter.  Compared to the Sequential Quarter, Segment Adjusted EBITDA Expense per ton increased 6.7% in the Illinois Basin resulting primarily from reduced production at our Hamilton mine due to a longwall move and difficult mining conditions during the 2018 Quarter and increased labor and materials and supplies expenses per ton at our Warrior mine.  In Appalachia, Segment Adjusted EBITDA Expense per ton decreased 3.9% compared to the Sequential Quarter primarily due to increased production and improved recoveries at our Tunnel Ridge mine in the 2018 Quarter.

Market Update and Outlook

"Favorable seaborne thermal coal markets continue to create significant opportunities for ARLP," said Mr. Craft.  "Around the world, increased coal-fired power generation, strong power demand and lack of supply response point to sustained global demand for U.S thermal coal producers.  Positive fundamentals in the international metallurgical coal markets also support continued participation by U.S. producers.  As mentioned earlier, ARLP has significantly increased its international presence and now expects to export 10.4 million tons of thermal coal in 2018 and has current commitments for 7.7 million tons of thermal coal in 2019.  In addition, we currently plan to export approximately 930,000 tons of metallurgical coal in 2018 and have commitments to deliver 100,000 tons of metallurgical coal in 2019.  In the U.S. markets served by ARLP, higher natural gas prices, expected weather-related load increases and significantly lower utility inventories continue to support constructive market dynamics.  Domestic utilities are actively looking to fill open positions, with several seeking longer-term supply commitments into 2021."

Mr. Craft continued, "ARLP is continuing to respond to strong coal demand in our markets.  By bringing Gibson North back into production, increasing mining units at River View and making infrastructure investments to improve productivity at several operations, ARLP expects to increase 2018 coal production by approximately 8.0% over 2017 levels.  Production in 2019 will benefit from the full-year impact of these 2018 capital projects leading to increased production in 2019 by

6% to 10% over 2018 levels.  ARLP has also secured volume and price commitments for approximately 32.9 million tons, 17.7 million tons and 7.9 million tons in 2019, 2020 and 2021, respectively, some of which is subject to customer requirements."

Factoring in the impact of cost increases year-to-date and training costs for additional headcount currently being hired in anticipation of the increased production discussed above, we currently anticipate full-year Segment Adjusted EBITDA Expense per ton in 2018 will be approximately 4.5% higher compared to 2017.  Accordingly, we are updating guidance ranges for 2018 full-year net income to $415.0 million to $425.0 million and EBITDA to $730.0 million to $740.0 million.  These 2018 estimates for net income and EBITDA include the $80.0 million settlement gain recorded in the first quarter of 2018 and expected contribution related to our current investments in oil and gas minerals and gas compression services of approximately $35.0 million to $40.0 million. (For a definition of EBITDA and Segment Adjusted EBITDA Expense per ton and related reconciliations to the most comparable GAAP financial measure, please see the end of this release.)

To fund our growing production, ARLP is also increasing its 2018 full-year guidance for capital expenditures for its coal business to a range of $245.0 million to $260.0 million.

Reconciliation of GAAP "net income attributable to ARLP" and "net income" to non-GAAP "EBITDA,"  "Adjusted EBITDA" and "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 and Adjusted EBITDA is EBITDA modified for certain items that may not reflect the trend of future results, such as settlement gains and debt extinguishment losses.  Distributable cash flow ("DCF") is defined as Adjusted EBITDA excluding interest expense (before capitalized interest), interest income, income taxes and estimated maintenance capital expenditures.  Distribution coverage ratio ("DCR") is defined as DCF divided by distributions paid to partners. 

Management believes that the presentation of such additional financial measures provides useful information to investors regarding our performance and results of operations because these measures, when used in conjunction with related GAAP financial measures, (i) provide additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provide investors with the financial analytical framework upon which management bases financial, operational, compensation and planning decisions and (iii) present measurements that investors, rating agencies and debt holders have indicated are useful in assessing us and our results of operations.

EBITDA, Adjusted EBITDA, DCF and DCR should not be considered as alternatives to net income attributable to ARLP, net income, income from operations, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP.  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, DCF and DCR may not be the same method used to compute similar measures reported by other companies, or EBITDA, Adjusted EBITDA, DCF and DCR 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 "Adjusted EBITDA" to "Segment Adjusted EBITDA" and "Segment Adjusted EBITDA per ton" (in thousands, except per ton data).

Segment Adjusted EBITDA Expense per ton includes operating expenses, 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 and Adjusted 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. 

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, general and administrative expenses, settlement gain and debt extinguishment loss divided by tons sold.  Segment Adjusted EBITDA removes the impact of general and administrative expenses from Adjusted EBITDA (discussed above) to allow management to focus solely on the evaluation of segment operating performance.
