Alliance Resource Partners, L.P.: Another Quarter of Record Revenues, EBITDA and Net Income Keep ARLP On Track For Eleventh Consecutive Year of Record Financial Performance; Quarterly Cash Distribution Increased 3.5% to $0.955 Per Unit

TULSA, Okla., Oct 28, 2011 (BUSINESS WIRE) -- Alliance Resource Partners, L.P. (NASDAQ: ARLP) today reported record financial results for the quarter ended September 30, 2011 (the "2011 Quarter"). Record coal sales volumes and pricing drove revenues in the 2011 Quarter to a record $487.7 million, an increase of 18.8% compared to the quarter ended September 30, 2010 (the "2010 Quarter"). ARLP also posted records in the 2011 Quarter for EBITDA, which increased 28.0% to $152.8 million; net income, which climbed 42.2% to $104.1 million; and net income per basic and diluted partner unit, which increased 45.9% to $2.16 per unit, each as compared to the 2010 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 increased the cash distribution to unitholders for the 2011 Quarter to $0.955 per unit (an annualized rate of $3.82 per unit), payable on November 14, 2011 to all unitholders of record as of the close of trading on November 7, 2011. The announced distribution represents a 15.1% increase over the cash distribution of $0.83 per unit for the 2010 Quarter and a 3.5% increase over the cash distribution of $0.9225 per unit for the second quarter of 2011 (the "Sequential Quarter").

"ARLP enjoyed another strong quarter on several fronts," said Joseph W. Craft III, President and Chief Executive Officer. "In addition to posting record financial results, ARLP also continued to build for the future. During the quarter, we sold approximately 28.4 million tons of coal to be delivered over the next five years. We also completed the recently announced transactions with White Oak Resources and began construction of the new Gibson South mine. With record setting performance to date, a solid sales contract portfolio and significant growth on the horizon, ARLP was once again able to deliver another distribution increase to our unitholders."

Consolidated Financial Results

Three Months Ended September 30, 2011 Compared to Three Months Ended September 30, 2010

Record coal sales volumes and pricing drove revenues in the 2011 Quarter to a record $487.7 million, an increase of 18.8% compared to the 2010 Quarter. Improved pricing under ARLP's coal sales contracts and increased pricing of export market sales pushed average coal sales prices in the 2011 Quarter higher by 10.1% to a record $56.89 per ton sold. Coal sales volumes climbed 8.5% in the 2011 Quarter to a record 8.3 million tons on the strength of higher sales volumes, particularly at the River View and Pattiki mines, as well as increased brokerage sales. Production increases at the River View, Pattiki and Gibson North mines contributed to a 9.3% increase in coal production volumes.

The increase in coal production and sales tons contributed to higher operating expenses in the 2011 Quarter, which increased 11.5% to $294.8 million. Operating expenses during the 2011 Quarter were particularly impacted by higher materials and supplies expenses, labor-related expenses, sales-related expenses and maintenance costs. Operating expenses during the 2011 Quarter also reflect increased costs associated with incidental production at the Tunnel Ridge mine development project and higher expenses related to a longwall move at the Mountain View mine.

Depreciation, depletion and amortization increased $2.7 million to $40.3 million in the 2011 Quarter compared to the 2010 Quarter, primarily as a result of capital expenditures related to expansion of production capacity at the River View mine and infrastructure and equipment expenditures at various other operations. In addition, outside coal purchases increased $14.1 million, compared to the 2010 Quarter, due to increased brokerage activity and higher cost per ton of purchased coal.

Nine Months Ended September 30, 2011 Compared to Nine Months Ended September 30, 2010

For the nine months ended September 30, 2011 (the "2011 Period"), ARLP reported records for all major operating and financial metrics. Led by increased production and sales volumes at River View, tons produced climbed 8.4% and tons sold increased 5.4%. Higher coal sales volumes and increased average coal sales prices, which rose $4.87 per ton sold, combined to drive 2011 Period revenues up 14.9% to $1.4 billion. For the 2011 Period, EBITDA increased 20.2% to $441.6 million and net income jumped 27.4% to $297.7 million, or $6.19 of net income per basic and diluted limited partner unit.

ARLP sold a record 8.3 million tons of coal in the 2011 Quarter, an increase of 8.5% over the 2010 Quarter and 5.5% over the Sequential Quarter. Increased coal sales volumes in the Illinois Basin primarily reflect continued strong sales performance from the River View mine and the resumption of full production at the Pattiki mine earlier this year, as compared to both the 2010 and Sequential Quarters. Increased sales volumes from both the MC Mining and Pontiki mines drove Central Appalachian coal sales volumes higher compared to the 2010 Quarter. Sequentially, challenging geological conditions at the Pontiki mine and the impact of stringent regulatory compliance on productivity contributed to lower Central Appalachian coal sales volumes in the 2011 Quarter. A longwall move at the Mountain View mine resulted in lower Northern Appalachian coal sales volumes in the 2011 Quarter, compared to both the 2010 and Sequential Quarters. Total coal inventories fell to approximately 555,000 tons at the end of the 2011 Quarter, a decrease of approximately 101,000 tons and 279,000 tons from inventories at the end of the 2010 and Sequential Quarters, respectively. ARLP currently anticipates coal inventories to continue to trend lower throughout the balance of this year.

Compared to the 2010 Quarter, coal prices improved in all of ARLP's operating regions during the 2011 Quarter. In particular, increased price realizations in Northern Appalachia from coal sold into the high priced export markets drove ARLP's total average coal sales prices up by 10.1% to a record $56.89 per ton sold. Sequentially, coal sales prices increased 1.4% due primarily to strong export market pricing in the Northern Appalachian region and improved contract pricing in the Illinois Basin region.

Total Segment Adjusted EBITDA Expense per ton in the 2011 Quarter increased 7.5% and 2.9% compared to the 2010 and Sequential Quarters, respectively. Higher total Segment Adjusted EBITDA Expense per ton during the 2011 Quarter reflected the previously discussed increases in consolidated coal sales, coal production and operating expenses, as well as the continuing impact on costs and productivity from increasingly stringent regulatory compliance requirements in all of our operating regions. In the Illinois Basin, increased labor costs and lower coal production and recoveries at the Warrior and Dotiki mines due to difficult mining conditions contributed to higher Segment Adjusted EBITDA Expense per ton in the 2011 Quarter, compared to both the 2010 and Sequential Quarters. In Central Appalachia, Segment Adjusted EBITDA Expense per ton for the 2011 Quarter improved compared to the 2010 Quarter due to the previously discussed increases in coal sales and production at the MC Mining and Pontiki mines. Sequentially, Segment Adjusted EBITDA Expense per ton increased in Central Appalachia due to the previously discussed geologic issues at the Pontiki mine and the impact of seasonal miners' vacation schedules. Higher Segment Adjusted EBITDA Expense per ton in Northern Appalachia reflects increased cost per ton of purchased coal, the longwall move at the Mountain View mine and expenses related to the Tunnel Ridge mine development project, offset in part by improved coal recoveries compared to the 2010 Quarter.

Outlook

Commenting on Alliance's outlook Mr. Craft continued, "As mentioned earlier, ARLP continues to build for the future and is focused on growing long-term cash flow on a sustainable basis. Near term, we expect 2012 to be another growth year for ARLP. The start up of our new longwall operation at Tunnel Ridge is targeted to add approximately 4.0 million tons of coal sales and production next year and, with our recent contracting efforts, ARLP now has over 90% of anticipated 2012 total coal sales committed at prices above current realizations. Longer term, our new Gibson South mine is currently scheduled to start initial production in 2014, adding another 3.0 - 3.5 million tons once the mine reaches full capacity. In addition, our recent transactions with White Oak are expected to significantly impact ARLP's cash flows beginning in 2015."

Based on results to date and current estimates, ARLP continues to anticipate 2011 coal sales in a range of 32.0 to 33.0 million tons, substantially all of which is committed and priced. Beyond 2011, ARLP has secured coal sales commitments for approximately 34.0 million tons, 33.2 million tons and 26.3 million tons in 2012, 2013 and 2014, respectively, of which approximately 7.7 million tons in 2013 and 7.1 million tons in 2014 remain open to market pricing.

ARLP also continues to expect full year results within its previously provided guidance ranges for 2011 revenues, excluding transportation revenues, of $1.80 to $1.85 billion, EBITDA of $550.0 to $585.0 million, and net income of $355.0 to $385.0 million. In addition, based on current schedules for ongoing capital projects, ARLP is anticipating 2011 total capital expenditures, including maintenance capital expenditures, in a range of $420.0 to $475.0 million. (For a definition of EBITDA and related reconciliations to comparable GAAP financial measures, please see the end of this release.)

Reconciliation of GAAP "Cash Flows Provided by Operating Activities" to non-GAAP "EBITDA" and Reconciliation of non-GAAP "EBITDA" to GAAP "Net Income" (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:

  • 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.

EBITDA should not be considered as an alternative 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 is not intended to represent cash flow and does not represent the measure of cash available for distribution. Our method of computing EBITDA may not be the same method used to compute similar measures reported by other companies, or EBITDA 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 thousand, 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.
