Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported financial and operating results for the quarter ended March 31, 2016 (the "2016 Quarter"). Net income in the 2016 Quarter was $47.3 million, or $0.36 per basic and diluted limited partner unit, compared to $106.5 million, or $0.92 per basic and diluted limited partner unit, for the quarter ended March 31, 2015 (the "2015 Quarter"). Total revenues were $412.8 million in the 2016 Quarter compared to $560.4 million in the 2015 Quarter, primarily resulting from planned reductions in coal sales and production volumes and lower other sales and operating revenues following our acquisition of the remaining equity interests in White Oak Resources LLC ("White Oak") in July 2015 (the "White Oak Acquisition"). Lower revenues were offset in part by reduced operating expenses and equity in loss of affiliates related to White Oak and led to EBITDA of $135.8 million for the 2016 Quarter, compared to $192.2 million for the 2015 Quarter. (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") has decreased the quarterly cash distribution to unitholders for the 2016 Quarter to $0.4375 per unit (an annualized rate of $1.75 per unit), payable on May 13, 2016 to all unitholders of record as of the close of trading on May 6, 2016. The announced distribution compares to quarterly unitholder distributions of $0.6625 per unit for the 2015 Quarter and $0.675 per unit for the quarter ended December 31, 2015 (the "Sequential Quarter").

"ARLP’s operating and financial performance for the 2016 Quarter was in line with our expectations as our results remained solid in the face of an extremely challenging coal market," said Joseph W. Craft III, President and Chief Executive Officer. "Although ARLP’s performance continues to lead the industry and our balance sheet remains strong, we are unfortunately being impacted by the contagion caused by the financial struggles facing many of our competitors. In the current capital market environment, it has become clear that we must be proactive in preserving liquidity in order to maintain access to capital. The decision by our Board to reduce ARLP’s unitholder distribution, while difficult, is a significant step toward maintaining that access."

Mr. Craft continued, "ARLP’s guidance for 2016 distributable cash flow has not changed from our year-end earnings release. For unitholders, this new distribution level provides stability as it meaningfully improves ARLP’s coverage to nearly 2.0x for the remaining three quarters of 2016 and an estimated 1.6x at the midpoint of current guidance for the 2016 calendar year. In the near term, we intend to use our excess cash flow to reduce indebtedness and further strengthen our balance sheet. Longer term, we are focused on growing our cash flows and returning to our past practice of steadily increasing distributions to our unitholders."

Consolidated Financial Results

Three Months Ended March 31, 2016 Compared to Three Months Ended March 31, 2015

Coal sales revenues in the 2016 Quarter were $401.3 million as compared to $517.7 million for the 2015 Quarter primarily as a result of lower coal sales and production volumes due to idling our Onton and Gibson North mines in the Sequential Quarter, the planned depletion of reserves at our Elk Creek mine in the 2016 Quarter and reduced production at our River View, Pattiki, Warrior, Tunnel Ridge and MC Mining operations. Compared to the 2015 Quarter, these reductions were partially offset by volumes from the Hamilton mine acquired as part of the White Oak Acquisition discussed above. ARLP’s coal sales revenue was also impacted by lower total average coal sales price realizations in the 2016 Quarter, which fell approximately 1.2% to $53.82 per ton sold compared to $54.49 per ton sold for the 2015 Quarter.

Other sales and operating revenues were $5.0 million in the 2016 Quarter compared to $35.5 million for the 2015 Quarter due to the absence of coal royalty and surface facilities revenues from White Oak as discussed above and the receipt in the 2015 Quarter of certain customer payments in lieu of shipments related to an Appalachian coal sales contract.

Operating expenses in the 2016 Quarter decreased 24.2% to $253.3 million primarily as a result of the previously discussed reduction of coal production volumes, a favorable production cost mix due to ARLP’s initiative to reduce production from higher-cost operations and a build in coal inventory at various mines. The lower-cost production mix and reduced selling expenses also contributed to decreased Segment Adjusted EBITDA Expense per ton, which improved 3.6% to $33.96 in the 2016 Quarter compared to the 2015 Quarter.

Depreciation, depletion and amortization increased $2.6 million to $80.9 million in the 2016 Quarter compared to the 2015 Quarter, due to the addition of the Hamilton mine partially offset by the impact of idling the Onton and Gibson North mines in the Sequential Quarter and reduced production at our Elk Creek mine. Equity in loss of affiliates decreased $9.7 million primarily due to the absence of losses in the 2016 Quarter related to our equity ownership in White Oak prior to the White Oak Acquisition.

Total tons sold in the 2016 Quarter decreased 21.5% and 25.2% compared to the 2015 and Sequential Quarters, respectively, as a result of planned reductions of coal sales volumes in both the Illinois Basin and Appalachian regions. Lower Illinois Basin coal sales volumes reflect the idling of our Onton and Gibson North mines in the Sequential Quarter, customer deferrals of scheduled shipments during the 2016 Quarter at our River View and Gibson South mines and reduced production at our Hamilton mine. In Appalachia, lower coal sales volumes in the 2016 Quarter were primarily due to the planned scale back of production at our Tunnel Ridge and MC Mining operations in response to weak coal demand and customer deferrals in the 2016 Quarter. Customer deferrals and soft coal demand due to a mild winter and excessive customer stockpiles also contributed to an inventory build at our mines of approximately 1.4 million tons during the 2016 Quarter.

Reflecting challenging market conditions and lower-priced legacy contracts at the Hamilton mine obtained in conjunction with the White Oak Acquisition, ARLP's total coal sales price per ton in the 2016 Quarter decreased 1.2% compared to the 2015 Quarter. Sequentially, total coal sales price per ton increased by 2.1% due to a favorable Illinois Basin sales mix in the 2016 Quarter.

Total Segment Adjusted EBITDA Expense per ton improved by 3.6% compared to the 2015 Quarter as a result of reduced expenses per ton in both the Illinois Basin and Appalachian regions. In the Illinois Basin, Segment Adjusted EBITDA Expense per ton decreased by 4.2% compared to the 2015 Quarter primarily due to a favorable production mix in the 2016 Quarter as discussed above and improved recoveries at our Gibson South and Warrior mines. Segment Adjusted EBITDA Expense per ton in Appalachia decreased by 2.9% compared to the 2015 Quarter as a result of lower selling expenses and inventory charges at our Tunnel Ridge and MC Mining mines, offset in part by lower recoveries across the region. Sequentially, total Segment Adjusted EBITDA Expense per ton increased 2.3% as a result of increased expenses per ton in the Illinois Basin partially offset by lower expenses per ton in Appalachia. Higher expenses per ton in the Illinois Basin reflect higher inventory charges at various mines, the planned reduction of lower-cost longwall production at Hamilton due to reduced coal demand and high customer inventory levels compared to the Sequential Quarter. The impact of reduced production at Hamilton was offset in part by improved recoveries at Gibson South and planned volume reductions at certain higher-cost mines in the Illinois Basin during the 2016 Quarter as discussed above. Expenses per ton declined in Appalachia during the Sequential Quarter primarily due to increased production and lower inventory charges at the Tunnel Ridge mine.

Outlook

"Coming into 2016, we expected lower coal demand for our Illinois Basin and northern Appalachian markets due to tepid power demand, persistently low natural gas prices, excess utility stockpiles and regulatory impacts," said Mr. Craft. "Mild weather conditions during the 2016 Quarter exacerbated these conditions, keeping the coal markets oversupplied and intensifying pressure on producers to curtail supply. Supply rationalization is occurring rapidly as evidenced by U.S. coal production falling by approximately 30% year-over-year in the 2016 Quarter, and we anticipate production cuts are likely to accelerate throughout the rest of the year. We continue to view current natural gas prices as unsustainable, eventually setting the stage for improved coal demand as gas supplies and pricing are impacted by significant reductions in drilling capital."

Mr. Craft added, "We expect the coal markets will remain oversupplied for several quarters and near-term pricing will be challenging. Later this year the reducing supply picture for both coal and natural gas should support higher prices for both commodities, and we are beginning to see some signs of increased buying interest for 2017. As utilities make their purchasing decisions for 2017 and beyond, we believe ARLP will benefit from our strategically-located, low-cost operations and strong balance sheet. We are unwavering in our commitment to deliver long-term value to our unitholders and believe ARLP is well positioned to deliver on this commitment."

Based on results to date and expectations for the balance of 2016, ARLP is maintaining its previous 2016 full-year ranges for coal production of 33.7 to 35.7 million tons, coal sales volumes of 34.6 to 38.1 million tons and revenues, excluding transportation revenues, of $1.82 to $1.95 billion. EBITDA continues to be estimated in a range of $545.0 to $615.0 million and net income in a range of $230.0 to $300.0 million. (For a definition of EBITDA and related reconciliation to the most comparable GAAP financial measure, please see the end of this release.)

ARLP has secured volume and price commitments for approximately 34.5 million tons in 2016 and has also secured coal sales and price commitments for approximately 21.5 million tons, 14.5 million tons and 7.1 million tons in 2017, 2018 and 2019, respectively.

Capital expenditures of $33.3 million during the 2016 Quarter were below our expectations and ARLP continues to evaluate opportunities to minimize future capital expenditures. As a result, we are reducing anticipated 2016 total capital expenditures by approximately $27.0 million at the midpoint of prior guidance to a range of $105.0 to $115.0 million. In addition to these capital expenditures, ARLP continues to anticipate funding investments in 2016 of $60.0 to $70.0 million related to its commitment to acquire oil and gas mineral interests.

Reconciliation of GAAP "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 non-cash impairments and gains and losses on acquisition related accounting. 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 items that may not reflect the trend of future results.

Distributable cash flow ("DCF") is defined as Adjusted EBITDA excluding equity in income or loss of affiliates, 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. DCF and DCR are used as supplemental financial measures 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 throughout 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, DCF and DCR 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, 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).

(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 2016 planning horizon, average annual estimated maintenance capital expenditures are assumed to be $4.75 per produced ton compared to the estimated $4.96 per produced ton in 2015. 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 "Adjusted 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 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. 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, general and administrative expenses, asset impairment charge and acquisition gain, net 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.
