Organization

ARLP is a Delaware limited partnership listed on the NASDAQ Global Select Market under the ticker symbol "ARLP."  ARLP was formed in May 1999 to acquire, upon completion of ARLP's initial public offering on August 19, 1999, certain coal production and marketing assets of Alliance Resource Holdings, Inc., a Delaware corporation ("ARH"), consisting of substantially all of ARH's operating subsidiaries, but excluding ARH.  ARH is owned by Joseph W. Craft III, the President and Chief Executive Officer and a Director of our managing general partner, and Kathleen S. Craft.  SGP, a Delaware limited liability company, is owned by ARH and holds a 0.01% general partner interest in each of ARLP and the Intermediate Partnership. 

We are managed by MGP, a Delaware limited liability company, which holds a 0.99% and a 1.0001% managing general partner interest in ARLP and the Intermediate Partnership, respectively, and a 0.001% managing member interest in Alliance Coal.  AHGP is a Delaware limited partnership that was formed to become the owner and controlling member of MGP.  AHGP completed its initial public offering on May 15, 2006.  AHGP owns directly and indirectly 100% of the members' interest of MGP, the incentive distribution rights ("IDR") in ARLP and 31,088,338 common units of ARLP. ARLP and its consolidated subsidiaries represent virtually all the net assets and operations of AHGP.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts and operations of the ARLP Partnership and present the consolidated financial position as of March 31, 2017 and December 31, 2016 and the results of operations, comprehensive income and cash flows for the three months ended March 31, 2017 and 2016 of ARLP, the Intermediate Partnership (a subsidiary of ARLP and a variable interest entity of which ARLP is the primary beneficiary), Alliance Coal (a subsidiary of the Intermediate Partnership and a variable interest entity of which the Intermediate Partnership is the primary beneficiary) and other directly and indirectly wholly- and majority-owned subsidiaries of the Intermediate Partnership and Alliance Coal.  The Intermediate Partnership, Alliance Coal and their wholly- and majority-owned subsidiaries represent virtually all the net assets of the ARLP Partnership.  MGP's interests in both Alliance Coal and the Intermediate Partnership and SGP's 0.01% interest in the Intermediate Partnership are reported as part of the overall

5

two percent general partner interest in the ARLP Partnership.  MGP's IDR in ARLP are also reported with the general partner interest in ARLP.  All intercompany transactions and accounts have been eliminated.  See Note 7 – Variable Interest Entities for more information regarding ARLP's consolidation of the Intermediate Partnership and Alliance Coal.  See Note 9 – Net Income of ARLP Per Limited Partner Unit for more information regarding MGP's IDR in ARLP.

These condensed consolidated financial statements and notes are unaudited. However, in the opinion of management, these financial statements reflect all normal recurring adjustments necessary for a fair presentation of the results for the periods presented.  Results presented for prior periods have been recast to reflect an immaterial reclassification of depreciation, depletion, and amortization capitalized into coal inventory as an adjustment to Depreciation, depletion, and amortization rather than Operating expenses (excluding depreciation, depletion, and amortization).  This reclassification did not impact Total operating expenses,  Income from operations,  Net income, Net income of ARLP or Basic and diluted net income of ARLP per limited partner unit.    Results for interim periods are not necessarily indicative of results to be expected for the full year ending December 31, 2017.  

These condensed consolidated financial statements and notes are prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim reporting and do not include all of the information normally included with financial statements prepared in accordance with generally accepted accounting principles ("GAAP") of the United States.  These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Use of Estimates

The preparation of the ARLP Partnership's condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in our condensed consolidated financial statements.  Actual results could differ from those estimates.

2.NEW ACCOUNTING STANDARDS

New Accounting Standards Issued and Adopted

In January 2017, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2017-04, Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04").  The ASU simplifies the subsequent measurement of goodwill by eliminating the need for an entity to determine the implied fair value of goodwill to calculate an impairment charge.  Under the new guidance an entity compares the fair value of the reporting unit containing the goodwill to its carrying value and records any excess carrying value as an impairment charge.  We have early adopted this new standard and will apply the guidance to any future goodwill impairment assessments.

In March 2016, the FASB issued ASU 2016-09, Compensation–Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09").  ASU 2016-09 simplifies the accounting for several aspects of share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, flexibility in the accounting for forfeitures and classification on the statement of cash flows.  ASU 2016-09 was effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted.  The adoption of ASU 2016-09 did not have a material impact on our condensed consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory ("ASU 2015-11").  ASU 2015-11 simplifies the subsequent measurement of inventory.  It replaces the current lower of cost or market test with the lower of cost or net realizable value test.  Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.  The new standard was applied prospectively and was effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods, with early adoption permitted.  The adoption of ASU 2015-11 did not have a material impact on our condensed consolidated financial statements.

6

New Accounting Standards Issued and Not Yet Adopted

In March 2017, the FASB issued ASU 2017-07, Compensation–Retirement Benefits (Topic 715) ("ASU 2017-07").  ASU 2017-07 requires that an employer disaggregate the service cost component from the other components of net benefit cost.  It also provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization.  The new guidance will be applied retroactively to all periods presented.  ASU 2017-07 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods.  We are currently evaluating the effect of adopting ASU 2017-07, but do not anticipate it will have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13").  ASU 2016-13 changes the impairment model for most financial assets and certain other instruments to require the use of a new forward-looking "expected loss" model that generally will result in earlier recognition of allowances for losses.  The new standard will require disclosure of significantly more information related to these items.  ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for the fiscal year beginning after December 15, 2018, including interim periods.  We are currently evaluating the effect of adopting ASU 2016-13, but do not anticipate it will have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02").  ASU 2016-02 increases transparency and comparability among organizations by requiring lessees to record right-to-use assets and corresponding lease liabilities on the balance sheet and disclosing key information about lease arrangements.  The new guidance will classify leases as either finance or operating (similar to current standard’s  "capital" or "operating" classification), with classification affecting the pattern of income recognition in the statement of income.  ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted.  We are currently evaluating the effect of adopting ASU 2016-02.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09").  ASU 2014-09 is a new revenue recognition standard that provides a five-step analysis of transactions to determine when and how revenue is recognized.  The core principle of the new standard is as follows:

An entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. 

ASU 2014-09 was originally effective for fiscal years, and interim periods within those years, beginning after December 15, 2016.  In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date ("ASU 2015-14"), which deferred the effective date by one year while providing the option to early adopt the standard on the original effective date. 

We have developed an assessment team to determine the effect of adopting ASU 2014-09.  As part of our assessment process, we applied the five-step analysis outlined in the new standard to certain contracts representative of the majority of our coal sales contracts and determined that our pattern of recognition appears consistent between both the new and existing standards. We have also reviewed the expanded disclosure requirements under the new standard and determined the additional information to be disclosed.  In addition we are in the process of reviewing our business processes, systems and internal controls over financial reporting to support the new recognition and disclosure requirements under the new standard.  The assessment team continues to report our implementation progress for the new standard to our management and audit committee of our managing general partner ("Audit Committee"). 

We continue to monitor closely, a) activities of the FASB and various non-authoritative groups with respect to implementation issues that might impact our determinations, b) existing contracts for consistency with current implementation determinations derived from our assessment process and c) our revenue recognition policy, where applicable, for required modifications.  We expect to complete this review in the first half of 2017.

We do not expect that the adoption of the new standard will have a material impact on our financial statements, but will require expanded disclosures including presenting, by type and by segment, revenues for all periods presented and

7

expected revenues by year for performance obligations that are unsatisfied or partially unsatisfied as of the date of presentation.  The new standard allows for two methods of adoption: a full retrospective adoption method, which requires the recasting of prior periods presented as if the new standard were in effect with a cumulative effect adjustment to equity at the beginning of the earliest period presented and a modified retrospective method which allows a cumulative effect adjustment to equity as of the date of adoption.  Because we do not anticipate a change in our pattern of revenue recognition, we anticipate that neither method will have a material impact on our consolidated financial statements.

3.CONTINGENCIES

Various lawsuits, claims and regulatory proceedings incidental to our business are pending against the ARLP Partnership.  We record accruals for potential losses related to these matters when, in management's opinion, such losses are probable and reasonably estimable.  Based on known facts and circumstances, we believe the ultimate outcome of these outstanding lawsuits, claims and regulatory proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity.  However, if the results of these matters were different from management's current opinion and in amounts greater than our accruals, then they could have a material adverse effect.

4.INVENTORIES

Inventories consist of the following:

	March 31,		December 31,
	2017		2016
	(in thousands)
Coal	$	44,160	$	29,242
Supplies (net of reserve for obsolescence of $5,340 and $4,940, respectively)		33,711		31,809
Total inventories, net	$	77,871	$	61,051

5.FAIR VALUE MEASUREMENTS

The following table summarizes our fair value measurements within the hierarchy:

	March 31, 2017						December 31, 2016
	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3
	(in thousands)
Measured on a recurring basis:
Contingent consideration	$	—	$	—	$	9,700	$	—	$	—	$	9,700
Additional disclosures:
Long-term debt		—		538,876		—		—		559,509		—
Total	$	—	$	538,876	$	9,700	$	—	$	559,509	$	9,700

The carrying amounts for cash equivalents, accounts receivable, accounts payable, accrued and other liabilities, due from affiliates and due to affiliates approximate fair value due to the short maturity of those instruments.

The estimated fair value of our long-term debt, including current maturities, is based on interest rates that we believe are currently available to us in active markets for issuance of debt with similar terms and remaining maturities (See Note 6 – Long-Term Debt).  The fair value of debt, which is based upon these interest rates, is classified as a Level 2 measurement under the fair value hierarchy.

The estimated fair value of our contingent consideration arrangement is based on a probability-weighted discounted cash flow model.  The assumptions in the model include a risk-adjusted discount rate, forward coal sales price curves, cost of debt and probabilities of meeting certain contractual threshold coal sales prices.  The fair value measurement is based on significant inputs not observable in active markets and thus represents a Level 3 fair value measurement under the fair value hierarchy.

On January 27, 2017, our Intermediate Partnership entered into a Fourth Amended and Restated Credit Agreement (the "Credit Agreement") with various financial institutions for a revolving credit facility and term loan (the "Credit Facility").  The Credit Facility replaced the $250 million term loan ("Replaced Term Loan") and $700 million revolving credit facility ("Replaced Revolving Credit Facility") extended to the Intermediate Partnership on May 23, 2012 (the "Replaced Credit Agreement") by various banks and other lenders that would have expired on May 23, 2017. 

The Credit Agreement provided for a $776.5 million revolving credit facility, reducing to $490.75 million on May 23, 2017, including a sublimit of $125 million for the issuance of letters of credit and a sublimit of $15.0 million for swingline borrowings (the "Revolving Credit Facility"), and for a term loan with a remaining principal balance of $50.0 million (the "Term Loan").  The outstanding revolver balance and term loan balance under the Replaced Credit Agreement were deemed to have been advanced under the Credit Facility on January 27, 2017.  On April 3, 2017, we entered into an amendment to the Credit Agreement (the "Amendment") to extend the termination date of the Revolving Credit Facility as to $457.25 million of commitments to May 23, 2021, eliminate the Cavalier Condition and the Senior Notes Condition (both as defined in the Credit Agreement) and effectuate certain other changes.  In connection with the Amendment, we increased the commitments under the Revolving Credit Facility from $479.75 million to $490.75 million, effective May 23, 2017.

The Credit Agreement is guaranteed by all of the material direct and indirect subsidiaries of our Intermediate Partnership, and is secured by substantially all of the Intermediate Partnership’s assets.  The Term Loan aggregate remaining outstanding principal balance of $50.0 million will be paid in full in May 2017.

Borrowings under the Credit Facility bear interest, at the option of the Intermediate Partnership, at either (i) the Base Rate at the greater of three benchmarks or (ii) a Eurodollar Rate, plus margins for (i) or (ii), as applicable, that fluctuate depending upon the ratio of Consolidated Debt to Consolidated Cash Flow (each as defined in the Credit Agreement).  The Revolving Credit Facility bears a lower interest rate for Non-Extending Lenders during their brief participation period which ends May 23, 2017 compared to rates associated with the new lenders and Extending Lenders which are in effect through termination of the Revolving Credit Facility.  We elected a Eurodollar Rate, which, with applicable margin, was 3.12% on borrowings outstanding as of March 31, 2017.  At March 31, 2017, we had borrowings of $230.0 million and $8.6 million of letters of credit outstanding with $537.9 million available for borrowing under the Revolving Credit Facility. We currently incur a weighted average annual commitment fee of 0.31% on the undrawn portion of the Revolving Credit Facility.  We utilize the Revolving Credit Facility, as appropriate, for working capital requirements, capital expenditures and investments in affiliates, scheduled debt payments and distribution payments. 

On January 27, 2017, the Intermediate Partnership also amended the 2008 Note Purchase Agreement dated June 26, 2008, for $145.0 million of Series B Senior Notes which bear interest at 6.72% and are due to mature on June 26, 2018 with interest payable semi-annually.  The amendment provided for certain modifications to the terms and provisions of the Note Purchase Agreement, including granting liens on substantially all of the Intermediate Partnership's assets to secure its obligations under the Note Purchase Agreement on an equal basis with the obligations under the Credit

9

Agreement.  The amendment also modified certain covenants to align them with the applicable covenants in the Credit Agreement.  As discussed below, we intend to repay the Series B Senior Notes in May 2017.

The Credit Agreement and the Series B Senior Notes (collectively, "ARLP Debt Arrangements") contain various restrictions affecting our Intermediate Partnership and its subsidiaries including, among other things, incurrence of additional indebtedness and liens, sale of assets, investments, mergers and consolidations and transactions with affiliates, in each case subject to various exceptions, and the payment of cash distributions by our Intermediate Partnership if such payment would result in a certain fixed charge coverage ratio (as defined in the ARLP Debt Arrangements).  The Amendment lowered this fixed charge ratio from less than 1.25 to 1.0 to 1.15 to 1.0 for each rolling four-quarter period and further limited the Intermediate Partnership’s ability to incur certain unsecured debt. See Note 7 – Variable Interest Entities for further discussion of restrictions on the cash available for distribution.  The Amendment also removed the requirement for the Intermediate Partnership to remain in control of a certain amount of mineable coal reserves relative to its annual production.  The ARLP Debt Arrangements require the Intermediate Partnership maintain (a) a debt to cash flow ratio of not more than 2.25 to 1.0 and (b) a cash flow to interest expense ratio of not less than 3.0 to 1.0, in each case, during the four most recently ended fiscal quarters.  The debt to cash flow ratio and cash flow to interest expense ratio were 0.80 to 1.0 and 25.5 to 1.0, respectively, for the trailing twelve months ended March 31, 2017.  We were in compliance with the covenants of the ARLP Debt Arrangements as of March 31, 2017.

On April 24, 2017, the Intermediate Partnership and Alliance Resource Finance Corporation(as co-issuer), a wholly owned subsidiary of the Intermediate Partnership("Alliance Finance"), issued an aggregate principal amount of $400.0 million of senior unsecured notes due 2025 ("Senior Notes") in a private placement to qualified institutional buyers.The Senior Notes have a term of eight years, maturing on May 1, 2025 (the "Term") and accrue interest at an annual rate of 7.5%.  Interest is payable semi-annually in arrears on each May 1 and November 1, commencing on November 1, 2017.  The indenture to the Senior Notes contains customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of distributions or similar restricted payments, undertaking transactions with affiliates and limitations on asset sales.  At any time prior to May 1, 2020, the issuers of the Senior Notes may redeem up to 35% of the aggregate principal amount of the Senior Notes at a redemption price equal to 107.5% of the principal amount redeemed, plus accrued and unpaid interest, if any, to the redemption date, with an amount of cash not greater than the net proceeds from one or more equity offerings.  The issuers of the Senior Notes may also redeem all or a part of the notes at any time on or after May 1, 2020, at redemption prices set forth in the indenture to the Senior Notes.  At any time prior to May 1, 2020, the issuers of the Senior Notes may redeem the Senior Notes at a redemption price equal to the principal amount of the Senior Notes plus a "make-whole" premium, plus accrued and unpaid interest, if any, to the redemption date.  The net proceeds from issuance of the Senior Notes and cash on hand were partially used to repay the Revolving Credit Facility and will partially be used to repay the Term Loan and the outstanding Series B Senior Notes in May 2017 (including a make-whole payment of approximately $8.9 million).  We incurred discount and debt issuance costs of approximately $9.0 million in connection with issuance of the Senior Notes which will be deferred and amortized as a component of interest expense over the Term.

On December 5, 2014, certain direct and indirect wholly-owned subsidiaries of our Intermediate Partnership entered into a $100.0 million accounts receivable securitization facility ("Securitization Facility") providing additional liquidity and funding.  Under the Securitization Facility, certain subsidiaries sell trade receivables on an ongoing basis to our Intermediate Partnership, which then sells the trade receivables to AROP Funding, LLC ("AROP Funding"), a wholly-owned bankruptcy-remote special purpose subsidiary of our Intermediate Partnership, which in turn borrows on a revolving basis up to $100.0 million secured by the trade receivables.  After the sale, Alliance Coal, as servicer of the assets, collects the receivables on behalf of AROP Funding.  The Securitization Facility bears interest based on a Eurodollar Rate.  It was renewed in December 2016 and matures in December 2017. At March 31, 2017, we had $100.0 million outstanding under the Securitization Facility. 

On October 6, 2015, Cavalier Minerals JV, LLC ("Cavalier Minerals") (see Note 7 – Variable Interest Entities) entered into a credit agreement (the "Cavalier Credit Agreement") with Mineral Lending, LLC ("Mineral Lending") for a $100.0 million line of credit (the "Cavalier Credit Facility").  Mineral Lending is an entity owned by a) Alliance Resource Holdings II, Inc. ("ARH II," the parent of ARH), b) an entity owned by an officer of ARH who is also a director of ARH II ("ARH Officer") and c) foundations established by the President and Chief Executive Officer of MGP and Kathleen S. Craft.  There is no commitment fee under the facility.  Borrowings under the Cavalier Credit Facility bear interest at a one month LIBOR rate plus 6% with interest payable quarterly.  Repayment of the principal balance will begin following the first fiscal quarter after the earlier of the date on which the aggregate amount borrowed exceeds $90.0 million or December 31, 2017, in quarterly payments of an amount equal to the greater of $1.3 million initially, escalated to $2.5 

10

million after two years, or fifty percent of Cavalier Minerals' excess cash flow. The Cavalier Credit Facility matures September 30, 2024, at which time all amounts then outstanding are required to be repaid.  To secure payment of the facility, Cavalier Minerals pledged all of its partnership interests, owned or later acquired, in AllDale Minerals, LP ("AllDale I") and AllDale Minerals II, LP ("AllDale II") (collectively "AllDale Minerals").  Cavalier Minerals may prepay the Cavalier Credit Facility at any time in whole or in part subject to terms and conditions described in the Cavalier Credit Agreement.  As of March 31, 2017, Cavalier Minerals had not drawn on the Cavalier Credit Facility.  Alliance Minerals, LLC ("Alliance Minerals") has the right to require Cavalier Minerals to draw the full amount available under the Cavalier Credit Facility and distribute the proceeds to the members of Cavalier Minerals, including Alliance Minerals. 

7.VARIABLE INTEREST ENTITIES

Cavalier Minerals

On November 10, 2014, our subsidiary, Alliance Minerals, and Bluegrass Minerals Management, LLC ("Bluegrass Minerals") entered into a limited liability company agreement (the "Cavalier Agreement") to create Cavalier Minerals, which was formed to indirectly acquire oil and gas mineral interests, initially through its 71.7% noncontrolling ownership interest in AllDale I and subsequently through its 72.8% noncontrolling ownership interest in AllDale II.  Bluegrass Minerals is owned and controlled by the ARH Officer discussed in Note 6 – Long-Term Debt and is Cavalier Minerals' managing member.  Alliance Minerals and Bluegrass Minerals initially committed funding of $48.0 million and $2.0 million, respectively, to Cavalier Minerals, and Cavalier Minerals committed funding of $49.0 million to AllDale I.  On October 6, 2015, Alliance Minerals and Bluegrass Minerals committed to fund an additional $96.0 million and $4.0 million, respectively, to Cavalier Minerals, and Cavalier Minerals committed to fund $100.0 million to AllDale II.  Contributions in the three months ended March 31, 2017 sufficiently completed funding to Cavalier Minerals for these commitments.  As of March 31, 2017, Cavalier Minerals is not expected to call on further funding of these commitments from Alliance Minerals and Bluegrass Minerals.

In accordance with the Cavalier Agreement, Bluegrass Minerals is entitled to receive an incentive distribution from Cavalier Minerals equal to 25% of all distributions (including in liquidation) after all members have recovered their investment.  The incentive distributions are reduced by certain distributions received by Bluegrass Minerals or its owner from AllDale Minerals Management, LLC ("AllDale Minerals Management"), the managing member of AllDale Minerals.  Distributions paid to Alliance Minerals and Bluegrass Minerals from Cavalier Minerals for each period presented are as follows:

Alliance Minerals' ownership interest in Cavalier Minerals at March 31, 2017 was 96%.  The remainder of the equity ownership is held by Bluegrass Minerals.  We have consolidated Cavalier Minerals' financial results as we concluded that Cavalier Minerals is a variable interest entity ("VIE") and we are the primary beneficiary because neither Bluegrass Minerals nor Alliance Minerals individually has both the power and the benefits related to Cavalier Minerals and we are most closely aligned with Cavalier Minerals through our substantial equity ownership.  Bluegrass Minerals’ equity ownership of Cavalier Minerals is accounted for as noncontrolling ownership interest in our condensed consolidated balance sheets.  In addition, earnings attributable to Bluegrass Minerals are recognized as noncontrolling interest in our condensed consolidated statements of income.

WKY CoalPlay

On November 17, 2014, SGP Land, LLC ("SGP Land"), a wholly-owned subsidiary of SGP, and two limited liability companies ("Craft Companies") owned by irrevocable trusts established by the President and Chief Executive Officer of MGP entered into a limited liability company agreement to form WKY CoalPlay, LLC ("WKY CoalPlay").  WKY CoalPlay was formed, in part, to purchase and lease coal reserves.  WKY CoalPlay is managed by the ARH Officer discussed in Note 6 – Long-Term Debt, who is also an employee of SGP Land and trustee of the irrevocable trusts owning the Craft Companies.  In December 2014 and February 2015, we entered into various coal reserve leases with WKY CoalPlay.  During the three months ended March 31, 2017, we paid $10.8 million of advanced royalties to WKY CoalPlay.  As of March 31, 2017, we had $30.1 million of advanced royalties outstanding under the leases, which is reflected in the Advance royalties, net line items in our condensed consolidated balance sheets. 

We have concluded that WKY CoalPlay is a VIE because of our ability to exercise options to acquire reserves under lease with WKY CoalPlay, which is not within the control of the equity holders and, if it occurs, could potentially limit the expected residual return to the owners of WKY CoalPlay.  We do not have any economic or governance rights related to WKY CoalPlay and our options that provide us with a variable interest in WKY CoalPlay's reserve assets do not give us any rights that constitute power to direct the primary activities that most significantly impact WKY CoalPlay's economic performance.  SGP Land has the sole ability to replace the manager of WKY CoalPlay at its discretion and therefore has power to direct the activities of WKY CoalPlay.  Consequently, we concluded that SGP Land is the primary beneficiary of WKY CoalPlay.

Alliance Coal and the Intermediate Partnership

Alliance Coal is a limited liability company designed to operate as the operating subsidiary of the Intermediate Partnership and holds the interests in the mining operations and Alliance Service, Inc. ("ASI").  The Intermediate Partnership is a limited partnership that holds the non-managing member interest in Alliance Coal and the sole member interests in Alliance Resource Properties, Alliance Minerals and other entities.  Together Alliance Coal and the Intermediate Partnership and their subsidiaries represent virtually all the net assets of ARLP.  Both the Intermediate Partnership and Alliance Coal were designed to operate as the operating subsidiaries of ARLP and to distribute available cash to ARLP so that ARLP can distribute available cash to its partners. We considered MGP's and ARLP's ownership in the Intermediate Partnership and MGP's and the Intermediate Partnership's ownership in Alliance Coal separately for the purposes of determining whether the Intermediate Partnership and Alliance Coal are VIEs.

12

The Intermediate Partnership holds a 99.999% non-managing interest and MGP holds the 0.001% managing member interest in Alliance Coal.  To determine whether Alliance Coal is a VIE, we considered that since Alliance Coal is structured as the equivalent of a limited partnership with the non-managing member 1) not having the ability to remove its managing member and 2) not participating significantly in the operational decisions, Alliance Coal represents a VIE.

We determined that neither the MGP nor the Intermediate Partnership have both the power and the benefits related to Alliance Coal.  We then considered which of the two was most closely aligned with Alliance Coal and thus would be designated the primary beneficiary of Alliance Coal for consolidation purposes.  We determined that the Intermediate Partnership was most closely aligned with Alliance Coal and is the primary beneficiary.  We based our determination of alignment on 1) the purpose and design of Alliance Coal which is to a) be the operating subsidiary of the Intermediate Partnership and b) distribute all of its available cash to the Intermediate Partnership such that the Intermediate Partnership can pay its partners and debt obligations, 2) AHGP's common control over both the Intermediate Partnership and MGP, as discussed in Note 1 – Organization and Presentation, to achieve the aforementioned purpose and design and 3) the Intermediate Partnership's debt funding for Alliance Coal for capital expenditures, operations and other purposes as needed and related risks and collateral requirements in the debt arrangements.

ARLP holds a 98.9899% limited partnership interest in the Intermediate Partnership and MGP holds the 1.0001% managing general partner interest in the Intermediate Partnership.  To determine whether the Intermediate Partnership is a VIE, we considered that since the Intermediate Partnership is structured as a limited partnership with the limited partner 1) not having the ability to remove its general partner and 2) not participating significantly in the operational decisions, the Intermediate Partnership represents a VIE.

We determined that neither the MGP nor ARLP have both the power and the benefits related to Intermediate Partnership.  We then considered which of the two was most closely aligned with the Intermediate Partnership and thus would be designated the primary beneficiary of the Intermediate Partnership for consolidation purposes.  We determined that ARLP was most closely aligned with the Intermediate Partnership and is the primary beneficiary.  We based our determination of alignment on 1) the purpose and design of the Intermediate Partnership which is to a) be the operating subsidiary to ARLP and b) distribute all of its available cash to ARLP to pay its partners and 2) AHGP's common control over ARLP, MGP and the Intermediate Partnership, as discussed in Note 1 – Organization and Presentation, to achieve the aforementioned purpose and design.

The effect of the partnership agreements of ARLP and the Intermediate Partnership and the operating agreement of Alliance Coal (collectively the "Agreements") is that on a quarterly basis 100% of available cash from our operations must be distributed by ARLP to its partners (apart from nominal distributions from the Intermediate Partnership and Alliance Coal to MGP and SGP).  Available cash is determined as defined in the Agreements and represents all cash with the exception of cash reserves (i) for the proper conduct of the business including reserves for future capital expenditures and for anticipated credit needs of the Partnership Group, (ii) to comply with debt obligations or (iii) to provide funds for certain subsequent distributions.  Cash reserves may not be established for the purpose of funding subsequent distributions if the effect would be to prevent ARLP from making the minimum quarterly distributions plus any cumulative distribution arrearage.  MGP, as the managing member of Alliance Coal and the managing general partner of the Intermediate Partnership, is responsible for distributing this cash to ARLP so it can meet its distribution requirements.  As discussed in Note 6 – Long-Term Debt, the Intermediate Partnership's debt covenants place additional restrictions on distributions to ARLP by limiting cash available for distribution from the Intermediate Partnership based on various debt covenants pertaining to the most recent preceding quarter.  MGP does not have the ability, without the consent of the limited partners, to amend the Agreements.

8.EQUITY INVESTMENT

AllDale Minerals

In November 2014, Cavalier Minerals (see Note 7 – Variable Interest Entities), was created to indirectly purchase, through its equity investments in AllDale Minerals, oil and gas mineral interests in various geographic locations within producing basins in the continental U.S.  In February 2017, Alliance Minerals committed to directly (rather than through Cavalier Minerals) invest $30.0 million in AllDale Minerals III, LP ("AllDale III") which was created for similar investment purposes.  We continually review all rights provided to Cavalier Minerals and us by various agreements and continue to conclude all such rights do not provide Cavalier Minerals or us the ability to unilaterally direct any of the activities of AllDale Minerals or AllDale III (collectively, the "AllDale Partnerships") that most significantly impact the 

13

economic performance of the AllDale Partnerships.  As such, we account for our ownership interest in the income or loss of the AllDale Partnerships as equity investments and it is so reflected in our condensed consolidated financial statements.  We record equity income or loss based on the AllDale Partnerships'  individual distribution structures.  The changes in our aggregate equity investment in the AllDale Partnerships for each of the periods presented were as follows:

Ending balance	$	147,052	$	84,234

9.NET INCOME OF ARLP PER LIMITED PARTNER UNIT

We utilize the two-class method in calculating basic and diluted earnings per unit ("EPU").  Net income of ARLP is allocated to the general partners and limited partners in accordance with their respective partnership percentages, after giving effect to any special income or expense allocations, including incentive distributions to our managing general partner, the holder of the IDR pursuant to our partnership agreement, which are declared and paid following the end of each quarter. Under the quarterly IDR provisions of our partnership agreement, our managing general partner is entitled to receive 15% of the amount we distribute in excess of $0.1375 per unit, 25% of the amount we distribute in excess of $0.15625 per unit, and 50% of the amount we distribute in excess of $0.1875 per unit.  Our partnership agreement contractually limits our distributions to available cash; therefore, undistributed earnings of the ARLP Partnership are not allocated to the IDR holder.  In addition, outstanding awards under our Long-Term Incentive Plan ("LTIP") and phantom units in notional accounts under our Supplemental Executive Retirement Plan ("SERP") and the MGP Amended and Restated Deferred Compensation Plan for Directors ("Deferred Compensation Plan") include rights to nonforfeitable distributions or distribution equivalents and are therefore considered participating securities.  As such, we allocate undistributed and distributed earnings to these outstanding awards in our calculation of EPU.  The following is a reconciliation of net income of ARLP used for calculating basic earnings per unit and the weighted-average units used in computing EPU for the three months ended March 31, 2017 and 2016:

Basic and diluted net income of ARLP per limited partner unit (1)		$	1.10	$	0.36

(1) Diluted EPU gives effect to all dilutive potential common units outstanding during the period using the treasury stock method. Diluted EPU excludes all dilutive potential units calculated under the treasury stock method if their effect is

14

anti-dilutive.  The combined total of LTIP, SERP and Deferred Compensation Plan units of 1,427 and 439 for the three months ended March 31, 2017 and 2016, respectively, were considered anti-dilutive under the treasury stock method.

During the three months ended March 31, 2017, an affiliated entity controlled by Mr. Craft made a capital contribution of $0.8 million to AHGP for the purpose of funding certain general and administrative expenses.  Upon AHGP's receipt of the contribution, it contributed the same to its subsidiary MGP, our managing general partner, which in turn contributed the same to our subsidiary, Alliance Coal.  As provided under our partnership agreement, we made a special allocation to our managing general partner of certain general and administrative expenses equal to its contribution.  Net income of ARLP allocated to the limited partners was not burdened by this expense.

10.WORKERS' COMPENSATION AND PNEUMOCONIOSIS

The changes in the workers' compensation liability, including current and long-term liability balances, for each of the periods presented were as follows:

(1) Amortization of net actuarial gain is included in the Operating expenses (excluding depreciation, depletion and amortization) line item within our condensed consolidated statements of income.

11.COMPENSATION PLANS

Long-Term Incentive Plan

We have the LTIP for certain employees and officers of MGP and its affiliates who perform services for us.  The LTIP awards are grants of non-vested "phantom" or notional units, also referred to as "restricted units", which upon satisfaction of time and performance-based vesting requirements, entitle the LTIP participant to receive ARLP common units.  Annual grant levels and vesting provisions for designated participants are recommended by the President and Chief Executive Officer of MGP, subject to review and approval of the compensation committee of the MGP board of directors (the "Compensation Committee").  Vesting of all grants outstanding are subject to the satisfaction of certain financial tests, which management currently believes are probable.  Grants issued to LTIP participants are expected to cliff vest on January 1st of the third year following issuance of the grants.  We expect to settle the non-vested LTIP grants by delivery of ARLP common units, except for the portion of the grants that will satisfy tax withholding obligations of LTIP participants.  As provided under the distribution equivalent rights provisions of the LTIP and the terms of the LTIP awards, all non-vested

15

grants include contingent rights to receive quarterly distributions in cash or, in the case of the 2016 and 2017 grants, at the discretion of the Compensation Committee, cash or in lieu of cash, phantom units credited to a bookkeeping account with value, equal to the cash distributions we make to unitholders during the vesting period. 

A summary of non-vested LTIP grants as of and for the three months ended March 31, 2017 is as follows:

	Number of units	Weighted average grant date fair value per unit		Intrinsic value
				(in thousands)
Non-vested grants at January 1, 2017	1,604,748	$	23.19	$	36,027
Granted	462,890		23.25
Vested (1)	(350,516)		40.73
Forfeited	(16,466)		21.22
Non-vested grants at March 31, 2017	1,700,656		19.61		36,819

(1) During the three months ended March 31, 2017, we issued 222,011 unrestricted common units to the LTIP participants.  The remaining vested units were settled in cash to satisfy tax withholding obligations of the LTIP participants.

For the three months ended March 31, 2017 and 2016, our LTIP expense was $2.6 million and $2.9 million, respectively.  The total obligation associated with the LTIP as of March 31, 2017 was $13.4 million and is included in the partners' capital Limited partners-common unitholders line item in our condensed consolidated balance sheets. As of March 31, 2017, there was $19.9 million in total unrecognized compensation expense related to the non-vested LTIP grants that are expected to vest.  That expense is expected to be recognized over a weighted-average period of 1.8 years.

After consideration of the January 1, 2017 vesting and subsequent issuance of 222,011 common units, approximately 2.5 million units remain available under the LTIP for issuance in the future, assuming all grants issued in 2017, 2016 and 2015 and currently outstanding are settled with common units, without reduction for tax withholding, and no future forfeitures occur.   

Supplemental Executive Retirement Plan and Directors Deferred Compensation Plan

We utilize the SERP to provide deferred compensation benefits for certain officers and key employees. All allocations made to participants under the SERP are made in the form of "phantom" ARLP units and SERP distributions will be settled in the form of ARLP common units.  The SERP is administered by the Compensation Committee. 

Our directors participate in the Deferred Compensation Plan. Pursuant to the Deferred Compensation Plan, for amounts deferred either automatically or at the election of the director, a notional account is established and credited with notional common units of ARLP, described in the Deferred Compensation Plan as "phantom" units.  Distributions from the Deferred Compensation Plan will be settled in the form of ARLP common units.

For both the SERP and Deferred Compensation Plan, when quarterly cash distributions are made with respect to ARLP common units, an amount equal to such quarterly distribution is credited to each participant's notional account as additional phantom units.  All grants of phantom units under the SERP and Deferred Compensation Plan vest immediately.

12.COMPONENTS OF PENSION PLAN NET PERIODIC BENEFIT COSTS

Eligible employees at certain of our mining operations participate in a defined benefit plan (the "Pension Plan") that we sponsor.  The Pension Plan is currently closed to new applicants and effective January 31, 2017, participants within the Pension Plan ("Participants") are no longer receiving benefit accruals for service.  The amendment did not affect pension benefits accrued prior to January 31, 2017.  All Participants can participate in enhanced benefit provisions under the defined contribution profit sharing and savings plan.  The benefit formula for the Pension Plan is a fixed dollar unit based on years of service.  Components of the net periodic benefit cost for each of the periods presented are as follows:

	Three Months Ended

(1) Amortization of prior service cost and net actuarial loss is included in the Operating expenses (excluding depreciation, depletion and amortization) line item within our condensed consolidated statements of income.

During the three months ended March 31, 2017, we made a contribution payment of $0.7 million to the Pension Plan for the 2016 plan year.  On April 17, 2017, we made a contribution payment of $0.6 million for the 2017 plan year.

13.SEGMENT INFORMATION

We operate in the eastern U.S. as a producer and marketer of coal to major utilities and industrial users.  We aggregate multiple operating segments into two reportable segments: Illinois Basin and Appalachia, and we have an "all other" category referred to as Other and Corporate.  Our reportable segments correspond to major coal producing regions in the eastern U.S.  Similar economic characteristics for our operating segments within each of these two reportable segments generally include coal quality, geology, coal marketing opportunities, mining and transportation methods and regulatory issues.  

The Illinois Basin reportable segment is comprised of multiple operating segments, including current operating mining complexes a) Webster County Coal, LLC's Dotiki mining complex, b) Gibson County Coal, LLC's mining complex, which includes the Gibson North (currently idled) and Gibson South mines, c) Warrior Coal, LLC's mining complex, d) River View Coal, LLC's mining complex and e) Hamilton County Coal, LLC’s mining complex.  The Gibson North mine has been idled since the fourth quarter of 2015 in response to market conditions.

(1) The elimination column represents the elimination of intercompany transactions and is primarily comprised of sales from the Matrix Group and MAC to our mining operations, coal sales and purchases between operations within different segments, sales of receivables to AROP Funding and insurance premiums paid to Wildcat Insurance.

18

(2) Revenues included in the Other and Corporate column are primarily attributable to the Matrix Group revenues, Mt. Vernon transloading revenues, administrative service revenues from affiliates, MAC revenues, Wildcat Insurance revenues and brokerage coal sales.

(3) Segment Adjusted EBITDA Expense includes operating expenses, coal purchases and other income. Transportation expenses are excluded as these expenses are passed through to our customers and consequently we do not realize any gain or loss on transportation revenues.  We review Segment Adjusted EBITDA Expense per ton for cost trends.  Results presented for Segment Adjusted EBITDA Expense for the three months ended March 31, 2016 have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as adjustments to Depreciation, depletion and amortization rather than Operating expenses (excluding depreciation, depletion and amortization).

The following is a reconciliation of consolidated Segment Adjusted EBITDA Expense to Operating expenses (excluding depreciation, depletion and amortization):

	Three Months Ended

Segment Adjusted EBITDA Expense	$	261,494	$	263,488
Other income		1,298		91
Operating expenses (excluding depreciation, depletion and amortization)	$	262,792	$	263,579

(4) Segment Adjusted EBITDA 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.  Management therefore is able to focus solely on the evaluation of segment operating profitability as it relates to our revenues and operating expenses, which are primarily controlled by our segments.  Results presented for Segment Adjusted EBITDA for the three months ended March 31, 2016 have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as adjustments to Depreciation, depletion and amortization rather than Operating expenses (excluding depreciation, depletion and amortization).  Consolidated Segment Adjusted EBITDA is reconciled to net income as follows:

Summary

We are a diversified producer and marketer of coal primarily to major United States ("U.S.") utilities and industrial users. We began mining operations in 1971 and, since then, have grown through acquisitions and internal development to become the second largest coal producer in the eastern U.S.  As is customary in the coal industry, we have entered into long-term coal supply agreements with many of our customers.  We operate eight underground mining complexes in Illinois, Indiana, Kentucky, Maryland and West Virginia, and operate a coal loading terminal on the Ohio River at Mt. Vernon, Indiana.

We have two reportable segments: Illinois Basin and Appalachia, and an "all other" category referred to as Other and Corporate.  Our reportable segments correspond to major coal producing regions in the eastern U.S.  Factors similarly affecting financial performance of our operating segments within each of these two reportable segments generally include coal quality, geology, coal marketing opportunities, mining and transportation methods and regulatory issues.

· Illinois Basin reportable segment is comprised of multiple operating segments, including the following current operating mining complexes: a) Webster County Coal, LLC's Dotiki mining complex; b) Gibson County Coal, LLC's mining complex, which includes the Gibson North (currently idled) and Gibson South mines; c) Warrior Coal, LLC's mining complex; d) River View Coal, LLC's mining complex ("River View") and e) Hamilton County Coal, LLC’s mining complex ("Hamilton").  The Gibson North mine has been idled since the fourth quarter of 2015 in response to market conditions.    

The Illinois Basin reportable segment also includes White County Coal, LLC's Pattiki mining complex ("Pattiki"); Hopkins County Coal, LLC's mining complex, which includes the Elk Creek mine ("Elk Creek"), the Pleasant View surface mineable reserves and the Fies underground project; Sebree Mining, LLC's mining complex ("Sebree"), which includes the Onton mine, Steamport, LLC and certain Sebree reserves; CR Services, LLC; CR Machine Shop, LLC; certain properties and equipment of Alliance Resource Properties; ARP Sebree, LLC; ARP Sebree South, LLC and UC Coal, LLC and its subsidiaries, UC Mining, LLC and UC Processing, LLC (collectively "UC Coal").  The Pattiki mine ceased production in December 2016.  The Elk Creek mine depleted its reserves in March 2016 and ceased production on April 1, 2016.  Our Onton mine has been idled since the fourth quarter of 2015 in response to market conditions.UC Coal equipment assets acquired in 2015 continue to be deployed as needed at various Illinois Basin operating mines.

20

· Appalachia reportable segment is comprised of multiple operating segments, including the Mettiki mining complex ("Mettiki"); the Tunnel Ridge, LLC mining complex ("Tunnel Ridge"); and the MC Mining, LLC mining complex ("MC Mining").  The Mettiki mining complex includes Mettiki Coal (WV), LLC's Mountain View mine and Mettiki Coal, LLC's preparation plant.

Three Months Ended March 31, 2017 Compared to Three Months Ended March 31, 2016

We reported net income attributable to ARLP of $104.9 million for the three months ended March 31, 2017 ("2017 Quarter") compared to $47.3 million for the three months ended March 31, 2016 ("2016 Quarter"). The increase of $57.6 million was due to increased coal sales volumes, which rose to 9.6 million tons sold in the 2017 Quarter compared to 7.5 million tons sold in the 2016 Quarter, higher other sales and operating revenues, lower depreciation, depletion and amortization, lower operating expenses and higher equity in earnings of affiliates from our investments in oil and gas mineral interests, offset in part by lower coal sales price realizations.  Total revenues increased to $461.1 million in the 2017 Quarter compared to $412.8 million in the 2016 Quarter as increased sales volumes and other sales and operating revenues more than offset lower coal sales prices.    Even though coal sales and production volumes increased by 28.9% and 15.0%, respectively,  for the 2017 Quarter, operating expenses were slightly lower compared to the 2016 Quarter  reflecting the benefits of our recent efficiency initiatives to shift production to lower-cost operations.  The favorable production cost mix in the 2017 Quarter significantly lowered operating expenses per ton sold compared to the 2016 Quarter.  Results presented for the 2016 Quarter have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as an adjustment to depreciation, depletion and amortization rather than operating expenses.

	Three Months Ended March 31,

Operating expenses	$	262,792	$	263,579	$	27.35	$	35.35

Coal sales.  Coal sales increased $37.4 million or 9.3% to $438.7 million for the 2017 Quarter from $401.3 million for the 2016 Quarter.  The increase in coal sales reflected the benefit of increased tons sold, which contributed $115.9 million in additional coal sales, partially offset by lower average coal sales prices, which reduced coal sales by $78.5 million.  Sales and production volumes rose to 9.6 million tons sold and 10.2 million tons produced in the 2017 Quarter compared to 7.5 million tons sold and 8.9 million tons produced in the 2016 Quarter, primarily due to strong performances at the Gibson South, River View, Hamilton and Tunnel Ridge mines.  Average coal sales prices decreased $8.17 per ton sold in the 2017 Quarter to $45.65 compared to $53.82 per ton sold in the 2016 Quarter, primarily as a result of the expiration and/or renegotiation of certain higher-priced long-term contracts in addition to a significant increase in lower price export tons shipped from our Illinois Basin mines partially offset by increased higher priced export shipments from our Mettiki mine.  There were no export shipments in the 2016 Quarter.

Operating expenses.  Operating expenses decreased 0.3% to $262.8 million for the 2017 Quarter from $263.6 million for the 2016 Quarter primarily as a result of the previously discussed favorable production cost mix.  On a per ton

21

basis, operating expenses decreased 22.6% to $27.35 per ton sold from $35.35 per ton sold in the 2016 Quarter, due primarily to the lower-cost production mix and increased sales and production volumes.  The most significant impacts on operating expenses are discussed below:

· Labor and benefit expenses per ton produced, excluding workers' compensation, decreased 25.3% to $8.70 per ton in the 2017 Quarter from $11.65 per ton in the 2016 Quarter.  This decrease of $2.95 per ton was primarily attributable to the increased mix of lower-cost production discussed above;

· Material and supplies expenses per ton produced decreased 12.3% to $8.81 per ton in the 2017 Quarter from $10.05 per ton in the 2016 Quarter.  The decrease of $1.24 per ton produced resulted primarily from the increased mix of lower-cost production discussed above and decreases of $0.33 per ton for power and fuel used in the mining process, $0.23 per ton in longwall subsidence expense, $0.20 per ton in outside services used in the mining process, $0.19 per ton for roof support and $0.17 per ton for certain ventilation expenses;

· Maintenance expenses per ton produced decreased 9.9% to $3.17 per ton in the 2017 Quarter from $3.52 per ton in the 2016 Quarter.  The decrease of $0.35 per ton produced was primarily due to the increased mix of lower-cost production discussed above; and

· Production taxes and royalties expenses incurred as a percentage of coal sales prices and volumes decreased $0.95 per produced ton sold in the 2017 Quarter compared to the 2016 Quarter primarily as a result of lower excise taxes per ton resulting from a favorable state production mix and lower average coal sales prices as discussed above.

Other sales and operating revenues.  Other sales and operating revenues were principally comprised of Mt. Vernon transloading revenues, Matrix Design sales, other outside services and administrative services revenue from affiliates.  Other sales and operating revenues increased to $12.7 million in the 2017 Quarter from $5.0 million in the 2016 Quarter.  The increase of $7.7 million was primarily due to increased mining technology product sales by Matrix Design and increased transloading revenues from Mt. Vernon.

Depreciation, depletion and amortization.  Depreciation, depletion and amortization expense decreased to $65.1 million in the 2017 Quarter from $70.6 million in the 2016 Quarter.  The decrease of $5.5 million resulted primarily from the depletion of reserves at our Elk Creek mine in the 2016 Quarter and closure of the Pattiki mine in the fourth quarter of 2016, offset in part by an increase in coal sales volumes at the Hamilton and Tunnel Ridge mines in the 2017 Quarter.

Equity in income (loss) of affiliates.  Equity in earnings of affiliates increased $3.7 million in the 2017 Quarter compared to the 2016 Quarter due toincreased earnings from our investments in the AllDale Partnerships.

Transportation revenues and expenses.  Transportation revenues and expenses were $9.6 million and $6.6 million for the 2017 and 2016 Quarters, respectively.  The increase of $3.0 million was primarily attributable to increased tonnage for which we arranged transportation at certain mines, partially offset by a decrease in average transportation rates in the 2017 Quarter.  The cost of transportation services are passed through to our customers.  Consequently, we do not realize any gain or loss on transportation revenues.

22

Segment Adjusted EBITDA.  Our 2017 Quarter Segment Adjusted EBITDA increased $50.9 million, or 35.7%, to $193.7 million from the 2016 Quarter Segment Adjusted EBITDA of $142.8 million.  Segment Adjusted EBITDA, tons sold, coal sales, other sales and operating revenues and Segment Adjusted EBITDA Expense by segment are:

Illinois Basin – Segment Adjusted EBITDA increased 1.4% to $106.3 million in the 2017 Quarter from $104.8 million in the 2016 Quarter.  The increase of $1.5 million was primarily attributable to decreased expenses per ton resulting from a favorable production mix, partially offset by lower coal sales, which decreased 5.6% to $266.9 million in the 2017

23

Quarter from $282.7 million in the 2016 Quarter.  The decrease of $15.8 million in coal sales primarily reflects lower average coal sales prices of $40.05 in the 2017 Quarter compared to $51.12 in the 2016 Quarter resulting from the expiration and/or renegotiation of certain higher-priced long-term contracts and 1.9 million tons of lower price export sales volumes, both in the 2017 Quarter. No export tons were sold in the 2016 Quarter. The lower sales prices were partially offset by increased tons sold, which increased 20.5% to 6.7 million tons in the 2017 Quarter compared to 5.5 million tons in the 2016 Quarter.  Higher coal sales volumes resulted from increased sales from our River View, Gibson South and Hamilton operations, in addition to the increased export volumes mentioned above, offset in part by the previously mentioned depletion of reserves at our Elk Creek mine in the 2016 Quarter and the closure of the Pattiki mine in the fourth quarter of 2016.  Segment Adjusted EBITDA Expense decreased 9.6% to $161.4 million in the 2017 Quarter from $178.6 million in the 2016 Quarter due to reduced per ton expenses.  Segment Adjusted EBITDA Expense per ton decreased $8.08 per ton sold to $24.22 from $32.30 per ton sold in the 2016 Quarter, primarily due to reduced selling expenses, a significant increase in low-cost longwall production and improved recoveries at the Hamilton mine, and increased production and improved recoveries at our River View and Gibson South operations, as well as certain cost decreases described above under "–Operating expenses."

Appalachia – Segment Adjusted EBITDA increased 99.6% to $73.2 million for the 2017 Quarter from $36.7 million in the 2016 Quarter.  The increase of $36.5 million was primarily attributable to increased tons sold, which rose 52.1% to 2.9 million tons sold in the 2017 Quarter compared to 1.9 million tons sold in the 2016 Quarter and lower Segment Adjusted EBITDA Expense per ton, offset in part by lower average coal sales prices.  Coal sales increased 45.5% to $167.8 million compared to $115.3 million in the 2016 Quarter.  The increase of $52.5 million primarily resulted from increased sales volumes from our Tunnel Ridge longwall operation in addition to increased export sales from our Mettiki and MC Mining mines offset in part by lower average coal sales prices, which decreased 4.4% to $57.26 per ton sold compared to $59.89 per ton sold in the 2016 Quarter primarily reflecting lower Tunnel Ridge price realizations.  Segment Adjusted EBITDA Expense increased 19.6% to $95.3 million in the 2017 Quarter from $79.7 million in the 2016 Quarter due to increased sales volumes.  However, Segment Adjusted EBITDA Expense per ton decreased $8.87 per ton sold to $32.53 compared to $41.40 per ton sold in the 2016 Quarter, as a result of increased production and sales volumes at our Tunnel Ridge mine resulting from improved recoveries and additional longwall production days due in part to no longwall move days during the 2017 Quarter, as well as certain other cost decreases described above under "–Operating expenses." 

Other and Corporate – In the 2017 Quarter, Segment Adjusted EBITDA increased $12.2 million compared to the 2016 Quarter primarily as a result of increased mining technology product sales by Matrix Design, increased transloading revenues from Mt. Vernon, as well as an increase in equity earnings from the AllDale Partnerships.  Segment Adjusted EBITDA Expense decreased to $17.8 million for the 2017 Quarter compared to $20.7 million for the 2016 Quarter primarily as a result of reduced intercompany coal brokerage activity.

Elimination – Segment Adjusted EBITDA Expense eliminations decreased in the 2017 Quarter to $13.1 million from $15.6 million in the 2016 Quarter and coal sales eliminations decreased to $11.2 million from $14.0 million, reflecting reduced intercompany coal brokerage activity.

Reconciliation of non-GAAP "Segment Adjusted EBITDA" to GAAP "net income" and reconciliation of non-GAAP "Segment Adjusted EBITDA Expense" to GAAP "Operating Expenses"

Segment Adjusted EBITDA (a non-GAAP financial measure) 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.  Segment Adjusted EBITDA is a key component of consolidated EBITDA, which is used as a supplemental financial measure by management and by external users of our financial statements such as investors, commercial banks, research analysts and others.  We believe that the presentation of EBITDA provides useful information to investors regarding our performance and results of operations because EBITDA, when used in conjunction with related GAAP financial measures, (i) provides additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provides investors with the financial analytical framework upon which we base financial, operational, compensation and planning decisions and (iii) presents a measurement that investors, rating agencies and debt holders have indicated is useful in assessing us and our results of operations.

Segment Adjusted EBITDA is also used as a supplemental financial measure by our management for reasons similar to those stated in the previous explanation of EBITDA.  In addition, the exclusion of corporate general and administrative expenses from consolidated Segment Adjusted EBITDA allows management to focus solely on the evaluation of segment operating profitability as it relates to our revenues and operating expenses, which are primarily

24

controlled by our segments.Results presented for Segment Adjusted EBITDA for the three months ended March 31, 2016 have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as adjustments to depreciation, depletion and amortization rather than operating expenses.

The following is a reconciliation of consolidated Segment Adjusted EBITDA to net income, the most comparable GAAP financial measure:

	Three Months Ended
	March 31,
	2017		2016

Interest expense, net		(7,492)		(7,612)
Income tax benefit		12		9
Net income	$	105,050	$	47,308

Segment Adjusted EBITDA Expense (a non-GAAP financial measure) includes operating expenses, coal purchases and other income.  Transportation expenses are excluded as these expenses are passed through to our customers and, consequently, we do not realize any gain or loss 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 Segment 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.  Results presented for Segment Adjusted EBITDA Expense for the three months ended March 31, 2016 have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as adjustments to depreciation, depletion and amortization rather than operating expenses.

Liquidity and Capital Resources

Liquidity

We have historically satisfied our working capital requirements and funded our capital expenditures, equity investments and debt service obligations with cash generated from operations, cash provided by the issuance of debt or equity, borrowings under credit and securitization facilities and sale-leaseback transactions.  We believe that existing cash balances, future cash flows from operations, borrowings under credit facilities, sale-leaseback transactions and cash provided from the issuance of debt or equity will be sufficient to meet our working capital requirements, capital expenditures and additional equity investments, debt payments, commitments and distribution payments.  Nevertheless, our ability to satisfy our working capital requirements, to fund planned capital expenditures and equity investments, to service our debt obligations or to pay distributions will depend upon our future operating performance and access to and cost of financing sources, which will be affected by prevailing economic conditions generally and in the coal industry specifically, as well as other financial and business factors, some of which are beyond our control.  Based on our recent operating results, current cash position, current unitholder distributions, anticipated future cash flows and sources of financing that we expect to have available, we do not anticipate any constraints to our liquidity at this time.  However, to the extent operating cash flow or access to and cost of financing sources are materially different than expected, future

25

liquidity may be adversely affected.  Please read "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2016.

Cash Flows

Cash provided by operating activities was $177.0 million for the 2017 Quarter compared to $80.6 million for the 2016 Quarter.  The increase in cash provided by operating activities was primarily due to an increase in net income as adjusted for non-cash items and favorable working capital changes related to trade receivables, coal inventories and accounts payable in the 2017 Quarter compared to the 2016 Quarter.

Net cash used in investing activities was $35.8 million for the 2017 Quarter compared to $57.3 million for the 2016 Quarter.  The decrease in cash used in investing activities was primarily attributable to decreased purchases of equity investments in affiliates and favorable changes in accounts payable related to property, plant and equipment purchases in the 2017 Quarter compared to the 2016 Quarter.

Net cash used in financing activities was $93.6 million for the 2017 Quarter compared to $26.8 million for the 2016 Quarter.  The increase in cash used in financing activities was primarily attributable to decreased net borrowings on securitization and revolving facilities, offset in part by reduced distributions paid to partners in the 2017 Quarter compared to the 2016 Quarter.

Capital Expenditures

Capital expenditures decreased marginally to $30.3 million in the 2017 Quarter from $31.7 million in the 2016 Quarter.

Our anticipated total capital expenditures for the year ending December 31, 2017 are estimated in a range of $145.0 million to $165.0 million, which includes expenditures for maintenance capital at various mines.  In addition to these capital expenditures, we anticipate funding in 2017 investments of approximately $20.0 million to $30.0 million related to our commitment to acquire oil and gas mineral interests.  Management anticipates funding remaining 2017 capital requirements with cash and cash equivalents ($87.4 million as of March 31, 2017), cash flows from operations, borrowings under revolving credit and securitization facilities and cash provided from the issuance of debt or equity.  We will continue to have significant capital requirements over the long-term, which may require us to incur debt or seek additional equity capital.  The availability and cost of additional capital will depend upon prevailing market conditions, the market price of our common units and several other factors over which we have limited control, as well as our financial condition and results of operations.

Debt Obligations

Credit Facility.On January 27, 2017, our Intermediate Partnership entered into a Fourth Amended and Restated Credit Agreement (the "Credit Agreement") with various financial institutions for a revolving credit facility and term loan (the "Credit Facility").  The Credit Facility replaced the $250 million term loan ("Replaced Term Loan") and $700 million revolving credit facility ("Replaced Revolving Credit Facility") extended to the Intermediate Partnership on May 23, 2012 (the "Replaced Credit Agreement") by various banks and other lenders that would have expired on May 23, 2017. 

The Credit Agreement provided for a $776.5 million revolving credit facility, reducing to $490.75 million on May 23, 2017, including a sublimit of $125 million for the issuance of letters of credit and a sublimit of $15.0 million for swingline borrowings (the "Revolving Credit Facility"), and for a term loan with a remaining principal balance of $50.0 million (the "Term Loan").  The outstanding revolver balance and term loan balance under the Replaced Credit Agreement were deemed to have been advanced under the Credit Facility on January 27, 2017.  On April 3, 2017, we entered into an amendment to the Credit Agreement (the "Amendment") to extend the termination date of the Revolving Credit Facility as to $457.25 million of commitments to May 23, 2021, eliminate the Cavalier Condition and the Senior Notes Condition (both as defined in the Credit Agreement) and effectuate certain other changes.    In connection with the Amendment, we increased the commitments under the Revolving Credit Facility from $479.75 million to $490.75 million, effective May 23, 2017.

26

The Credit Agreement is guaranteed by all of the material direct and indirect subsidiaries of our Intermediate Partnership, and is secured by substantially all of the Intermediate Partnership’s assets.  The Term Loan aggregate remaining outstanding principal balance of $50.0 million will be paid in full in May 2017.

Borrowings under the Credit Facility bear interest, at the option of the Intermediate Partnership, at either (i) the Base Rate at the greater of three benchmarks or (ii) a Eurodollar Rate, plus margins for (i) or (ii), as applicable, that fluctuate depending upon the ratio of Consolidated Debt to Consolidated Cash Flow (each as defined in the Credit Agreement).  The Revolving Credit Facility bears a lower interest rate for Non-Extending Lenders during their brief participation period which ends May 23, 2017 compared to rates associated with the new lenders and Extending Lenders which are in effect through termination of the Revolving Credit Facility.  We elected a Eurodollar Rate, which, with applicable margin, was 3.12% on borrowings outstanding as of March 31, 2017.  At March 31, 2017, we had borrowings of $230.0 million and $8.6 million of letters of credit outstanding with $537.9 million available for borrowing under the Revolving Credit Facility. We currently incur a weighted average annual commitment fee of 0.31% on the undrawn portion of the Revolving Credit Facility.  We utilize the Revolving Credit Facility, as appropriate, for working capital requirements, capital expenditures and investments in affiliates, scheduled debt payments and distribution payments.

Series B Senior Notes.  On January 27, 2017, the Intermediate Partnership amended the 2008 Note Purchase Agreement dated June 26, 2008, for $145.0 million of Series B Senior Notes which bear interest at 6.72% and are due to mature on June 26, 2018 with interest payable semi-annually.  The amendment provided for certain modifications to the terms and provisions of the Note Purchase Agreement, including granting liens on substantially all of the Intermediate Partnership's assets to secure its obligations under the Note Purchase Agreement on an equal basis with the obligations under the Credit Agreement.  The amendment also modified certain covenants to align them with the applicable covenants in the Credit Agreement.  As discussed below, we intend to repay the Series B Senior Notes in May 2017.

The Credit Agreement and the Series B Senior Notes (collectively, "ARLP Debt Arrangements") contain various restrictions affecting our Intermediate Partnership and its subsidiaries including, among other things, incurrence of additional indebtedness and liens, sale of assets, investments, mergers and consolidations and transactions with affiliates, in each case subject to various exceptions, and the payment of cash distributions by our Intermediate Partnership if such payment would result in a certain fixed charge coverage ratio (as defined in the ARLP Debt Arrangements).  The Amendment lowered this fixed charge ratio from less than 1.25 to 1.0 to 1.15 to 1.0 for each rolling four-quarter period and further limited the Intermediate Partnership’s ability to incur certain unsecured debt. See Note 7 – Variable Interest Entities for further discussion of restrictions on the cash available for distribution.  The Amendment also removed the requirement for the Intermediate Partnership to remain in control of a certain amount of mineable coal reserves relative to its annual production.  The ARLP Debt Arrangements require the Intermediate Partnership maintain (a) a debt to cash flow ratio of not more than 2.25 to 1.0 and (b) a cash flow to interest expense ratio of not less than 3.0 to 1.0, in each case, during the four most recently ended fiscal quarters.  The debt to cash flow ratio and cash flow to interest expense ratio were 0.80 to 1.0 and 25.5 to 1.0, respectively, for the trailing twelve months ended March 31, 2017.  We were in compliance with the covenants of the ARLP Debt Arrangements as of March 31, 2017.

Senior Notes. On April 24, 2017, the Intermediate Partnership and Alliance Finance (as co-issuer), a wholly owned subsidiary of the Intermediate Partnership, issued an aggregate principal amount of $400.0 million of senior unsecured notes due 2025 ("Senior Notes") in a private placement to qualified institutional buyers.The Senior Notes have a term of eight years, maturing on May 1, 2025 (the "Term") and accrue interest at an annual rate of 7.5%.  Interest is payable semi-annually in arrears on each May 1 and November 1, commencing on November 1, 2017.  The indenture to the Senior Notes contain customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of distributions or similar restricted payments, undertaking transactions with affiliates and limitations on asset sales.    At any time prior to May 1, 2020, the issuers of the Senior Notes may redeem up to 35% of the aggregate principal amount of the Senior Notes at a redemption price equal to 107.5% of the principal amount redeemed, plus accrued and unpaid interest, if any, to the redemption date, with an amount of cash not greater than the net proceeds from one or more equity offerings.  The issuers of the Senior Notes may also redeem all or a part of the notes at any time on or after May 1, 2020, at redemption prices set forth in the indenture to the Senior Notes.   At any time prior to May 1, 2020, the issuers of the Senior Notes may redeem the Senior Notes at a redemption price equal to the principal amount of the Senior Notes plus a "make-whole" premium, plus accrued and unpaid interest, if any, to the redemption date.    The net proceeds from issuance of the Senior Notes and cash on hand were partially used to repay the Revolving Credit Facility and will partially be used to repay the Term Loan and the outstanding Series B Senior Notes in May 2017 (including a make-whole payment of approximately $8.9 million).  We incurred discount and debt issuance costs of approximately $9.0 million in

27

connection with issuance of the Senior Notes which will be deferred and amortized as a component of interest expense over the Term

Accounts Receivable Securitization.  On December 5, 2014, certain direct and indirect wholly-owned subsidiaries of our Intermediate Partnership entered into a $100.0 million accounts receivable securitization facility ("Securitization Facility") providing additional liquidity and funding.  Under the Securitization Facility, certain subsidiaries sell trade receivables on an ongoing basis to our Intermediate Partnership, which then sells the trade receivables to AROP Funding, LLC ("AROP Funding"), a wholly-owned bankruptcy-remote special purpose subsidiary of our Intermediate Partnership, which in turn borrows on a revolving basis up to $100.0 million secured by the trade receivables.  After the sale, Alliance Coal, as servicer of the assets, collects the receivables on behalf of AROP Funding.  The Securitization Facility bears interest based on a Eurodollar Rate.  It was renewed in December 2016 and matures in December 2017.  At March 31, 2017, we had $100.0 million outstanding under the Securitization Facility.

Cavalier Credit Agreement.  On October 6, 2015, Cavalier Minerals entered into a credit agreement (the "Cavalier Credit Agreement") with Mineral Lending, LLC ("Mineral Lending") for a $100.0 million line of credit (the "Cavalier Credit Facility").  There is no commitment fee under the facility.  Borrowings under the Cavalier Credit Facility bear interest at a one month LIBOR rate plus 6% with interest payable quarterly.  Repayment of the principal balance will begin following the first fiscal quarter after the earlier of the date on which the aggregate amount borrowed exceeds $90.0 million or December 31, 2017, in quarterly payments of an amount equal to the greater of $1.3 million initially, escalated to $2.5 million after two years, or fifty percent of Cavalier Minerals' excess cash flow. The Cavalier Credit Facility matures September 30, 2024, at which time all amounts then outstanding are required to be repaid.  To secure payment of the facility, Cavalier Minerals pledged all of its partnership interests, owned or later acquired, in AllDale Minerals, LP and AllDale Minerals II, LP.  Cavalier Minerals may prepay the Cavalier Credit Facility at any time in whole or in part subject to terms and conditions described in the Cavalier Credit Agreement.  As of March 31, 2017, Cavalier Minerals had not drawn on the Cavalier Credit Facility.  Alliance Minerals has the right to require Cavalier Minerals to draw the full amount available under the Cavalier Credit Facility and distribute the proceeds to the members of Cavalier Minerals, including Alliance Minerals

Other.  In addition to the letters of credit available under the Credit Facility discussed above, we also have an agreement with one bank to provide additional letters of credit of $5.0 million to maintain surety bonds to secure our obligations for workers' compensation benefits.  At March 31, 2017, we had $5.0 million in letters of credit outstanding under the agreement.

Related-Party Transactions

We have continuing related-party transactions with MGP, AHGP and SGP and its affiliates. These related-party transactions relate principally to the provision of administrative services to AHGP and Alliance Resource Holdings II, Inc. and their respective affiliates, mineral leases with SGP and its affiliates, and agreements relating to the use of aircraft.  We also have transactions with WKY CoalPlay, LLC ("WKY CoalPlay") regarding three mineral leases and Bluegrass Minerals Management, LLC ("Bluegrass Minerals") and, through Alliance Minerals and Cavalier Minerals, the AllDale Partnerships to support the acquisition of oil and gas mineral interests.  For more information regarding WKY CoalPlay, the AllDale Partnerships and Bluegrass Minerals, please read "Item 1. Financial Statements (Unaudited) – Note 7. Variable Interest Entities" and "– Note 8. Equity Investment" of this Quarterly Report on Form 10-Q.  Please read our Annual Report on Form 10-K for the year ended December 31, 2016, "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations – Related-Party Transactions" for additional information concerning related-party transactions.

Other Information

White Oak IRS Notice

We received notice that the Internal Revenue Service issued White Oak Resources LLC a "Notice of Beginning of Administrative Proceeding" in conjunction with an audit of the income tax return of White Oak for the tax year ended December 31, 2011.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

We have significant long-term coal supply agreements.  Most of the long-term coal supply agreements are subject to price adjustment provisions, which periodically permit an increase or decrease in the contract price typically to reflect changes in specified indices or changes in production costs resulting from regulatory changes, or both.

We have exposure to price risk for supplies that are used directly or indirectly in the normal course of coal production such as steel, electricity and other supplies. We manage our risk for these items through strategic sourcing contracts for normal quantities required by our operations.  We do not utilize any commodity price-hedges or other derivatives related to these risks.

Credit Risk

Most of our sales tonnage is consumed by electric utilities.  Therefore, our credit risk is primarily with domestic electric power generators.  Our policy is to independently evaluate each customer’s creditworthiness prior to entering into transactions and to constantly monitor outstanding accounts receivable against established credit limits. When deemed appropriate by our credit management department, we will take steps to reduce our credit exposure to customers that do not meet our credit standards or whose credit has deteriorated. These steps may include obtaining letters of credit or cash collateral, requiring prepayment for shipments or establishing customer trust accounts held for our benefit in the event of a failure to pay.

Exchange Rate Risk

Almost all of our transactions are denominated in U.S. Dollars, and as a result, we do not have material exposure to currency exchange-rate risks.

Interest Rate Risk

Borrowings under the Credit Facility, Securitization Facility and Cavalier Credit Agreement are at variable rates and, as a result, we have interest rate exposure.  Historically, our earnings have not been materially affected by changes in interest rates.  We do not utilize any interest rate derivative instruments related to our outstanding debt.  We had $230.0 million in borrowings under the Replaced Revolving Credit Facility, $50.0 million outstanding under the Replaced Term Loan and $100.0 million in borrowings under the Securitization Facility at March 31, 2017.  A one percentage point increase in the interest rates related to the Replaced Credit Facility and Securitization Facility would result in an annualized increase in interest expense of $3.8 million, based on borrowing levels at March 31, 2017.  On April 3, 2017, we amended the Credit Facility.  For more information regarding the amended terms, see above under "–Debt Obligations."   With respect to our fixed-rate borrowings, a one percentage point increase in interest rates would result in a decrease of approximately $1.8 million in the estimated fair value of these borrowings.

As of March 31, 2017, the estimated fair value of the ARLP Debt Arrangements was approximately $538.9 million.  The fair values of long-term debt are estimated using discounted cash flow analyses, based upon our current incremental borrowing rates for similar types of borrowing arrangements as of March 31, 2017.  There were no other changes in our quantitative and qualitative disclosures about market risk as set forth in our Annual Report on Form 10-K for the year ended December 31, 2016.

29

ITEM 4.CONTROLS AND PROCEDURES

We maintain controls and procedures designed to provide reasonable assurance that information required to be disclosed in the reports we file with the Securities and Exchange Commission ("SEC") is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.  As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we have evaluated, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) of the Exchange Act) as of March 31, 2017.  Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that these controls and procedures are effective as of March 31, 2017.

During the quarterly period ended March 31, 2017, there have not been any changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified in connection with this evaluation that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

EXHIBIT 95.1

Federal Mine Safety and Health Act Information

Our mining operations are subject to extensive and stringent compliance standards established pursuant to the Federal Mine Safety and Health Act of 1977, as amended by the Federal Mine Improvement and New Emergency Response Act of 2006 (as amended, the "Mine Act").  MSHA monitors and rigorously enforces compliance with these standards, and our mining operations are inspected frequently.  Citations and orders are issued by MSHA under Section 104 of the Mine Act for violations of the Mine Act or any mandatory health or safety standard, rule, order or regulation promulgated under the Mine Act.  A Section 104(a) "Significant and Substantial" or "S&S" citation is generally issued in a situation where the conditions created by the violation do not cause imminent danger, but in the opinion of the MSHA inspector could significantly and substantially contribute to the cause and effect of a mine safety or health hazard.  During the three months ended March 31, 2017, our mines were subject to 1,813 MSHA inspection days with an average of only 0.09 S&S citations written per inspection day.

The Mine Act has been construed as authorizing MSHA to issue citations and orders pursuant to the legal doctrine of strict liability, or liability without regard to fault.  If, in the opinion of an MSHA inspector, a condition exists that violates the Mine Act or regulations promulgated thereunder, then a citation or order will be issued regardless of whether we had any knowledge of, or fault in, the existence of that condition.  Many of the Mine Act standards include one or more subjective elements, so that issuance of a citation often depends on the opinions or experience of the MSHA inspector involved and the frequency of citations will vary from inspector to inspector.

If we disagree with the assertions of an MSHA inspector, we may exercise our right to challenge those findings by "contesting" the citation or order pursuant to the procedures established by the Mine Act and its regulations.  During the three months ended March 31, 2017, our operating subsidiaries contested approximately 15.0% of all citations and 34.2% of S&S citations issued by MSHA inspectors.  These contest proceedings frequently result in the dismissal or modification of previously issued citations, substantial reductions in the penalty amounts originally assessed by MSHA, or both.

The Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank Act")  requires issuers to include in periodic reports filed with the SEC certain information relating to citations or orders for violations of standards under the Mine Act.  The following tables include information required by the Dodd-Frank Act for the three months ended March 31, 2017.    The mine data retrieval system maintained by MSHA may show information that is different than what is provided herein.  Any such difference may be attributed to the need to update that information on MSHA’s system and/or other factors.

Organization

ARLP is a Delaware limited partnership listed on the NASDAQ Global Select Market under the ticker symbol "ARLP."  ARLP was formed in May 1999 to acquire, upon completion of ARLP's initial public offering on August 19, 1999, certain coal production and marketing assets of Alliance Resource Holdings, Inc., a Delaware corporation ("ARH"), consisting of substantially all of ARH's operating subsidiaries, but excluding ARH.  ARH is owned by Joseph W. Craft III, the President and Chief Executive Officer and a Director of our managing general partner, and Kathleen S. Craft.  SGP, a Delaware limited liability company, is owned by ARH and holds a 0.01% general partner interest in each of ARLP and the Intermediate Partnership. 

We are managed by MGP, a Delaware limited liability company, which holds a 0.99% and a 1.0001% managing general partner interest in ARLP and the Intermediate Partnership, respectively, and a 0.001% managing member interest in Alliance Coal.  AHGP is a Delaware limited partnership that was formed to become the owner and controlling member of MGP.  AHGP completed its initial public offering on May 15, 2006.  AHGP owns directly and indirectly 100% of the members' interest of MGP, the incentive distribution rights ("IDR") in ARLP and 31,088,338 common units of ARLP. ARLP and its consolidated subsidiaries represent virtually all the net assets and operations of AHGP.

Basis of Presentation

The accompanying condensed consolidated financial statements include the accounts and operations of the ARLP Partnership and present the consolidated financial position as of March 31, 2017 and December 31, 2016 and the results of operations, comprehensive income and cash flows for the three months ended March 31, 2017 and 2016 of ARLP, the Intermediate Partnership (a subsidiary of ARLP and a variable interest entity of which ARLP is the primary beneficiary), Alliance Coal (a subsidiary of the Intermediate Partnership and a variable interest entity of which the Intermediate Partnership is the primary beneficiary) and other directly and indirectly wholly- and majority-owned subsidiaries of the Intermediate Partnership and Alliance Coal.  The Intermediate Partnership, Alliance Coal and their wholly- and majority-owned subsidiaries represent virtually all the net assets of the ARLP Partnership.  MGP's interests in both Alliance Coal and the Intermediate Partnership and SGP's 0.01% interest in the Intermediate Partnership are reported as part of the overall two percent general partner interest in the ARLP Partnership.  MGP's IDR in ARLP are also reported with the general partner interest in ARLP.  All intercompany transactions and accounts have been eliminated.  See Note 7 – Variable Interest Entities for more information regarding ARLP's consolidation of the Intermediate Partnership and Alliance Coal.  See Note 9 – Net Income of ARLP Per Limited Partner Unit for more information regarding MGP's IDR in ARLP.

These condensed consolidated financial statements and notes are unaudited. However, in the opinion of management, these financial statements reflect all normal recurring adjustments necessary for a fair presentation of the results for the periods presented.  Results presented for prior periods have been recast to reflect an immaterial reclassification of depreciation, depletion, and amortization capitalized into coal inventory as an adjustment to Depreciation, depletion, and amortization rather than Operating expenses (excluding depreciation, depletion, and amortization).  This reclassification did not impact Total operating expenses,  Income from operations,  Net income,  Net income of ARLP or Basic and diluted net income of ARLP per limited partner unit.  Results for interim periods are not necessarily indicative of results to be expected for the full year ending December 31, 2017.  

These condensed consolidated financial statements and notes are prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim reporting and do not include all of the information normally included with financial statements prepared in accordance with generally accepted accounting principles ("GAAP") of the United States.  These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Use of Estimates

The preparation of the ARLP Partnership's condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in our condensed consolidated financial statements.  Actual results could differ from those estimates.

NEW ACCOUNTING STANDARDS

NEW ACCOUNTING STANDARDS

2.NEW ACCOUNTING STANDARDS

New Accounting Standards Issued and Adopted

In January 2017, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2017-04, Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04").  The ASU simplifies the subsequent measurement of goodwill by eliminating the need for an entity to determine the implied fair value of goodwill to calculate an impairment charge.  Under the new guidance an entity compares the fair value of the reporting unit containing the goodwill to its carrying value and records any excess carrying value as an impairment charge.  We have early adopted this new standard and will apply the guidance to any future goodwill impairment assessments.

In March 2016, the FASB issued ASU 2016-09, Compensation–Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09").  ASU 2016-09 simplifies the accounting for several aspects of share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, flexibility in the accounting for forfeitures and classification on the statement of cash flows.  ASU 2016-09 was effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted.  The adoption of ASU 2016-09 did not have a material impact on our condensed consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory ("ASU 2015-11").  ASU 2015-11 simplifies the subsequent measurement of inventory.  It replaces the current lower of cost or market test with the lower of cost or net realizable value test.  Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.  The new standard was applied prospectively and was effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods, with early adoption permitted.  The adoption of ASU 2015-11 did not have a material impact on our condensed consolidated financial statements.

New Accounting Standards Issued and Not Yet Adopted

In March 2017, the FASB issued ASU 2017-07, Compensation–Retirement Benefits (Topic 715) ("ASU 2017-07").  ASU 2017-07 requires that an employer disaggregate the service cost component from the other components of net benefit cost.  It also provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization.  The new guidance will be applied retroactively to all periods presented.  ASU 2017-07 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods.  We are currently evaluating the effect of adopting ASU 2017-07, but do not anticipate it will have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13").  ASU 2016-13 changes the impairment model for most financial assets and certain other instruments to require the use of a new forward-looking "expected loss" model that generally will result in earlier recognition of allowances for losses.  The new standard will require disclosure of significantly more information related to these items.  ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted for the fiscal year beginning after December 15, 2018, including interim periods.  We are currently evaluating the effect of adopting ASU 2016-13, but do not anticipate it will have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) ("ASU 2016-02").  ASU 2016-02 increases transparency and comparability among organizations by requiring lessees to record right-to-use assets and corresponding lease liabilities on the balance sheet and disclosing key information about lease arrangements.  The new guidance will classify leases as either finance or operating (similar to current standard’s  "capital" or "operating" classification), with classification affecting the pattern of income recognition in the statement of income.  ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted.  We are currently evaluating the effect of adopting ASU 2016-02.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09").  ASU 2014-09 is a new revenue recognition standard that provides a five-step analysis of transactions to determine when and how revenue is recognized.  The core principle of the new standard is as follows:

An entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. 

ASU 2014-09 was originally effective for fiscal years, and interim periods within those years, beginning after December 15, 2016.  In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date ("ASU 2015-14"), which deferred the effective date by one year while providing the option to early adopt the standard on the original effective date. 

We have developed an assessment team to determine the effect of adopting ASU 2014-09.  As part of our assessment process, we applied the five-step analysis outlined in the new standard to certain contracts representative of the majority of our coal sales contracts and determined that our pattern of recognition appears consistent between both the new and existing standards. We have also reviewed the expanded disclosure requirements under the new standard and determined the additional information to be disclosed.  In addition we are in the process of reviewing our business processes, systems and internal controls over financial reporting to support the new recognition and disclosure requirements under the new standard.  The assessment team continues to report our implementation progress for the new standard to our management and audit committee of our managing general partner ("Audit Committee"). 

We continue to monitor closely, a) activities of the FASB and various non-authoritative groups with respect to implementation issues that might impact our determinations, b) existing contracts for consistency with current implementation determinations derived from our assessment process and c) our revenue recognition policy, where applicable, for required modifications.  We expect to complete this review in the first half of 2017.

We do not expect that the adoption of the new standard will have a material impact on our financial statements, but will require expanded disclosures including presenting, by type and by segment, revenues for all periods presented and expected revenues by year for performance obligations that are unsatisfied or partially unsatisfied as of the date of presentation.  The new standard allows for two methods of adoption: a full retrospective adoption method, which requires the recasting of prior periods presented as if the new standard were in effect with a cumulative effect adjustment to equity at the beginning of the earliest period presented and a modified retrospective method which allows a cumulative effect adjustment to equity as of the date of adoption.  Because we do not anticipate a change in our pattern of revenue recognition, we anticipate that neither method will have a material impact on our consolidated financial statements.

Various lawsuits, claims and regulatory proceedings incidental to our business are pending against the ARLP Partnership.  We record accruals for potential losses related to these matters when, in management's opinion, such losses are probable and reasonably estimable.  Based on known facts and circumstances, we believe the ultimate outcome of these outstanding lawsuits, claims and regulatory proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity.  However, if the results of these matters were different from management's current opinion and in amounts greater than our accruals, then they could have a material adverse effect.

The following table summarizes our fair value measurements within the hierarchy:

	Level 1		Level 2		Level 3		Level 1		Level 2		Level 3

Total	$	—	$	538,876	$	9,700	$	—	$	559,509	$	9,700

The carrying amounts for cash equivalents, accounts receivable, accounts payable, accrued and other liabilities, due from affiliates and due to affiliates approximate fair value due to the short maturity of those instruments.

The estimated fair value of our long-term debt, including current maturities, is based on interest rates that we believe are currently available to us in active markets for issuance of debt with similar terms and remaining maturities (See Note 6 – Long-Term Debt).  The fair value of debt, which is based upon these interest rates, is classified as a Level 2 measurement under the fair value hierarchy.

The estimated fair value of our contingent consideration arrangement is based on a probability-weighted discounted cash flow model.  The assumptions in the model include a risk-adjusted discount rate, forward coal sales price curves, cost of debt and probabilities of meeting certain contractual threshold coal sales prices.  The fair value measurement is based on significant inputs not observable in active markets and thus represents a Level 3 fair value measurement under the fair value hierarchy.

On January 27, 2017, our Intermediate Partnership entered into a Fourth Amended and Restated Credit Agreement (the "Credit Agreement") with various financial institutions for a revolving credit facility and term loan (the "Credit Facility").  The Credit Facility replaced the $250 million term loan ("Replaced Term Loan") and $700 million revolving credit facility ("Replaced Revolving Credit Facility") extended to the Intermediate Partnership on May 23, 2012 (the "Replaced Credit Agreement") by various banks and other lenders that would have expired on May 23, 2017. 

The Credit Agreement provided for a $776.5 million revolving credit facility, reducing to $490.75 million on May 23, 2017, including a sublimit of $125 million for the issuance of letters of credit and a sublimit of $15.0 million for swingline borrowings (the "Revolving Credit Facility"), and for a term loan with a remaining principal balance of $50.0 million (the "Term Loan").  The outstanding revolver balance and term loan balance under the Replaced Credit Agreement were deemed to have been advanced under the Credit Facility on January 27, 2017.  On April 3, 2017, we entered into an amendment to the Credit Agreement (the "Amendment") to extend the termination date of the Revolving Credit Facility as to $457.25 million of commitments to May 23, 2021, eliminate the Cavalier Condition and the Senior Notes Condition (both as defined in the Credit Agreement) and effectuate certain other changes.  In connection with the Amendment, we increased the commitments under the Revolving Credit Facility from $479.75 million to $490.75 million, effective May 23, 2017.

The Credit Agreement is guaranteed by all of the material direct and indirect subsidiaries of our Intermediate Partnership, and is secured by substantially all of the Intermediate Partnership’s assets.  The Term Loan aggregate remaining outstanding principal balance of $50.0 million will be paid in full in May 2017.

Borrowings under the Credit Facility bear interest, at the option of the Intermediate Partnership, at either (i) the Base Rate at the greater of three benchmarks or (ii) a Eurodollar Rate, plus margins for (i) or (ii), as applicable, that fluctuate depending upon the ratio of Consolidated Debt to Consolidated Cash Flow (each as defined in the Credit Agreement).  The Revolving Credit Facility bears a lower interest rate for Non-Extending Lenders during their brief participation period which ends May 23, 2017 compared to rates associated with the new lenders and Extending Lenders which are in effect through termination of the Revolving Credit Facility.  We elected a Eurodollar Rate, which, with applicable margin, was 3.12% on borrowings outstanding as of March 31, 2017.  At March 31, 2017, we had borrowings of $230.0 million and $8.6 million of letters of credit outstanding with $537.9 million available for borrowing under the Revolving Credit Facility. We currently incur a weighted average annual commitment fee of 0.31% on the undrawn portion of the Revolving Credit Facility.  We utilize the Revolving Credit Facility, as appropriate, for working capital requirements, capital expenditures and investments in affiliates, scheduled debt payments and distribution payments. 

On January 27, 2017, the Intermediate Partnership also amended the 2008 Note Purchase Agreement dated June 26, 2008, for $145.0 million of Series B Senior Notes which bear interest at 6.72% and are due to mature on June 26, 2018 with interest payable semi-annually.  The amendment provided for certain modifications to the terms and provisions of the Note Purchase Agreement, including granting liens on substantially all of the Intermediate Partnership's assets to secure its obligations under the Note Purchase Agreement on an equal basis with the obligations under the Credit Agreement.  The amendment also modified certain covenants to align them with the applicable covenants in the Credit Agreement.  As discussed below, we intend to repay the Series B Senior Notes in May 2017.

The Credit Agreement and the Series B Senior Notes (collectively, "ARLP Debt Arrangements") contain various restrictions affecting our Intermediate Partnership and its subsidiaries including, among other things, incurrence of additional indebtedness and liens, sale of assets, investments, mergers and consolidations and transactions with affiliates, in each case subject to various exceptions, and the payment of cash distributions by our Intermediate Partnership if such payment would result in a certain fixed charge coverage ratio (as defined in the ARLP Debt Arrangements).  The Amendment lowered this fixed charge ratio from less than 1.25 to 1.0 to 1.15 to 1.0 for each rolling four-quarter period and further limited the Intermediate Partnership’s ability to incur certain unsecured debt. See Note 7 – Variable Interest Entities for further discussion of restrictions on the cash available for distribution.  The Amendment also removed the requirement for the Intermediate Partnership to remain in control of a certain amount of mineable coal reserves relative to its annual production.  The ARLP Debt Arrangements require the Intermediate Partnership maintain (a) a debt to cash flow ratio of not more than 2.25 to 1.0 and (b) a cash flow to interest expense ratio of not less than 3.0 to 1.0, in each case, during the four most recently ended fiscal quarters.  The debt to cash flow ratio and cash flow to interest expense ratio were 0.80 to 1.0 and 25.5 to 1.0, respectively, for the trailing twelve months ended March 31, 2017.  We were in compliance with the covenants of the ARLP Debt Arrangements as of March 31, 2017.

On April 24, 2017, the Intermediate Partnership and Alliance Resource Finance Corporation(as co-issuer), a wholly owned subsidiary of the Intermediate Partnership("Alliance Finance"), issued an aggregate principal amount of $400.0 million of senior unsecured notes due 2025 ("Senior Notes") in a private placement to qualified institutional buyers.The Senior Notes have a term of eight years, maturing on May 1, 2025 (the "Term") and accrue interest at an annual rate of 7.5%.  Interest is payable semi-annually in arrears on each May 1 and November 1, commencing on November 1, 2017.  The indenture to the Senior Notes contains customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of distributions or similar restricted payments, undertaking transactions with affiliates and limitations on asset sales.  At any time prior to May 1, 2020, the issuers of the Senior Notes may redeem up to 35% of the aggregate principal amount of the Senior Notes at a redemption price equal to 107.5% of the principal amount redeemed, plus accrued and unpaid interest, if any, to the redemption date, with an amount of cash not greater than the net proceeds from one or more equity offerings.  The issuers of the Senior Notes may also redeem all or a part of the notes at any time on or after May 1, 2020, at redemption prices set forth in the indenture to the Senior Notes.  At any time prior to May 1, 2020, the issuers of the Senior Notes may redeem the Senior Notes at a redemption price equal to the principal amount of the Senior Notes plus a "make-whole" premium, plus accrued and unpaid interest, if any, to the redemption date.  The net proceeds from issuance of the Senior Notes and cash on hand were partially used to repay the Revolving Credit Facility and will partially be used to repay the Term Loan and the outstanding Series B Senior Notes in May 2017 (including a make-whole payment of approximately $8.9 million).  We incurred discount and debt issuance costs of approximately $9.0 million in connection with issuance of the Senior Notes which will be deferred and amortized as a component of interest expense over the Term.

On December 5, 2014, certain direct and indirect wholly-owned subsidiaries of our Intermediate Partnership entered into a $100.0 million accounts receivable securitization facility ("Securitization Facility") providing additional liquidity and funding.  Under the Securitization Facility, certain subsidiaries sell trade receivables on an ongoing basis to our Intermediate Partnership, which then sells the trade receivables to AROP Funding, LLC ("AROP Funding"), a wholly-owned bankruptcy-remote special purpose subsidiary of our Intermediate Partnership, which in turn borrows on a revolving basis up to $100.0 million secured by the trade receivables.  After the sale, Alliance Coal, as servicer of the assets, collects the receivables on behalf of AROP Funding.  The Securitization Facility bears interest based on a Eurodollar Rate.  It was renewed in December 2016 and matures in December 2017. At March 31, 2017, we had $100.0 million outstanding under the Securitization Facility. 

On October 6, 2015, Cavalier Minerals JV, LLC ("Cavalier Minerals") (see Note 7 – Variable Interest Entities) entered into a credit agreement (the "Cavalier Credit Agreement") with Mineral Lending, LLC ("Mineral Lending") for a $100.0 million line of credit (the "Cavalier Credit Facility").  Mineral Lending is an entity owned by a) Alliance Resource Holdings II, Inc. ("ARH II," the parent of ARH), b) an entity owned by an officer of ARH who is also a director of ARH II ("ARH Officer") and c) foundations established by the President and Chief Executive Officer of MGP and Kathleen S. Craft.  There is no commitment fee under the facility.  Borrowings under the Cavalier Credit Facility bear interest at a one month LIBOR rate plus 6% with interest payable quarterly.  Repayment of the principal balance will begin following the first fiscal quarter after the earlier of the date on which the aggregate amount borrowed exceeds $90.0 million or December 31, 2017, in quarterly payments of an amount equal to the greater of $1.3 million initially, escalated to $2.5 million after two years, or fifty percent of Cavalier Minerals' excess cash flow. The Cavalier Credit Facility matures September 30, 2024, at which time all amounts then outstanding are required to be repaid.  To secure payment of the facility, Cavalier Minerals pledged all of its partnership interests, owned or later acquired, in AllDale Minerals, LP ("AllDale I") and AllDale Minerals II, LP ("AllDale II") (collectively "AllDale Minerals").  Cavalier Minerals may prepay the Cavalier Credit Facility at any time in whole or in part subject to terms and conditions described in the Cavalier Credit Agreement.  As of March 31, 2017, Cavalier Minerals had not drawn on the Cavalier Credit Facility.  Alliance Minerals, LLC ("Alliance Minerals") has the right to require Cavalier Minerals to draw the full amount available under the Cavalier Credit Facility and distribute the proceeds to the members of Cavalier Minerals, including Alliance Minerals.

Cavalier Minerals 

On November 10, 2014, our subsidiary, Alliance Minerals, and Bluegrass Minerals Management, LLC ("Bluegrass Minerals") entered into a limited liability company agreement (the "Cavalier Agreement") to create Cavalier Minerals, which was formed to indirectly acquire oil and gas mineral interests, initially through its 71.7% noncontrolling ownership interest in AllDale I and subsequently through its 72.8% noncontrolling ownership interest in AllDale II.  Bluegrass Minerals is owned and controlled by the ARH Officer discussed in Note 6 – Long-Term Debt and is Cavalier Minerals' managing member.  Alliance Minerals and Bluegrass Minerals initially committed funding of $48.0 million and $2.0 million, respectively, to Cavalier Minerals, and Cavalier Minerals committed funding of $49.0 million to AllDale I.  On October 6, 2015, Alliance Minerals and Bluegrass Minerals committed to fund an additional $96.0 million and $4.0 million, respectively, to Cavalier Minerals, and Cavalier Minerals committed to fund $100.0 million to AllDale II.  Contributions in the three months ended March 31, 2017 sufficiently completed funding to Cavalier Minerals for these commitments.  As of March 31, 2017, Cavalier Minerals is not expected to call on further funding of these commitments from Alliance Minerals and Bluegrass Minerals.

Alliance Minerals' ownership interest in Cavalier Minerals at March 31, 2017 was 96%.  The remainder of the equity ownership is held by Bluegrass Minerals.  We have consolidated Cavalier Minerals' financial results as we concluded that Cavalier Minerals is a variable interest entity ("VIE") and we are the primary beneficiary because neither Bluegrass Minerals nor Alliance Minerals individually has both the power and the benefits related to Cavalier Minerals and we are most closely aligned with Cavalier Minerals through our substantial equity ownership.  Bluegrass Minerals’ equity ownership of Cavalier Minerals is accounted for as noncontrolling ownership interest in our condensed consolidated balance sheets.  In addition, earnings attributable to Bluegrass Minerals are recognized as noncontrolling interest in our condensed consolidated statements of income.

WKY CoalPlay

On November 17, 2014, SGP Land, LLC ("SGP Land"), a wholly-owned subsidiary of SGP, and two limited liability companies ("Craft Companies") owned by irrevocable trusts established by the President and Chief Executive Officer of MGP entered into a limited liability company agreement to form WKY CoalPlay, LLC ("WKY CoalPlay").  WKY CoalPlay was formed, in part, to purchase and lease coal reserves.  WKY CoalPlay is managed by the ARH Officer discussed in Note 6 – Long-Term Debt, who is also an employee of SGP Land and trustee of the irrevocable trusts owning the Craft Companies.  In December 2014 and February 2015, we entered into various coal reserve leases with WKY CoalPlay.  During the three months ended March 31, 2017, we paid $10.8 million of advanced royalties to WKY CoalPlay.  As of March 31, 2017, we had $30.1 million of advanced royalties outstanding under the leases, which is reflected in the Advance royalties, net line items in our condensed consolidated balance sheets. 

We have concluded that WKY CoalPlay is a VIE because of our ability to exercise options to acquire reserves under lease with WKY CoalPlay, which is not within the control of the equity holders and, if it occurs, could potentially limit the expected residual return to the owners of WKY CoalPlay.  We do not have any economic or governance rights related to WKY CoalPlay and our options that provide us with a variable interest in WKY CoalPlay's reserve assets do not give us any rights that constitute power to direct the primary activities that most significantly impact WKY CoalPlay's economic performance.  SGP Land has the sole ability to replace the manager of WKY CoalPlay at its discretion and therefore has power to direct the activities of WKY CoalPlay.  Consequently, we concluded that SGP Land is the primary beneficiary of WKY CoalPlay.

Alliance Coal and the Intermediate Partnership

Alliance Coal is a limited liability company designed to operate as the operating subsidiary of the Intermediate Partnership and holds the interests in the mining operations and Alliance Service, Inc. ("ASI").  The Intermediate Partnership is a limited partnership that holds the non-managing member interest in Alliance Coal and the sole member interests in Alliance Resource Properties, Alliance Minerals and other entities.  Together Alliance Coal and the Intermediate Partnership and their subsidiaries represent virtually all the net assets of ARLP.  Both the Intermediate Partnership and Alliance Coal were designed to operate as the operating subsidiaries of ARLP and to distribute available cash to ARLP so that ARLP can distribute available cash to its partners. We considered MGP's and ARLP's ownership in the Intermediate Partnership and MGP's and the Intermediate Partnership's ownership in Alliance Coal separately for the purposes of determining whether the Intermediate Partnership and Alliance Coal are VIEs.

The Intermediate Partnership holds a 99.999% non-managing interest and MGP holds the 0.001% managing member interest in Alliance Coal.  To determine whether Alliance Coal is a VIE, we considered that since Alliance Coal is structured as the equivalent of a limited partnership with the non-managing member 1) not having the ability to remove its managing member and 2) not participating significantly in the operational decisions, Alliance Coal represents a VIE.

We determined that neither the MGP nor the Intermediate Partnership have both the power and the benefits related to Alliance Coal.  We then considered which of the two was most closely aligned with Alliance Coal and thus would be designated the primary beneficiary of Alliance Coal for consolidation purposes.  We determined that the Intermediate Partnership was most closely aligned with Alliance Coal and is the primary beneficiary.  We based our determination of alignment on 1) the purpose and design of Alliance Coal which is to a) be the operating subsidiary of the Intermediate Partnership and b) distribute all of its available cash to the Intermediate Partnership such that the Intermediate Partnership can pay its partners and debt obligations, 2) AHGP's common control over both the Intermediate Partnership and MGP, as discussed in Note 1 – Organization and Presentation, to achieve the aforementioned purpose and design and 3) the Intermediate Partnership's debt funding for Alliance Coal for capital expenditures, operations and other purposes as needed and related risks and collateral requirements in the debt arrangements.

ARLP holds a 98.9899% limited partnership interest in the Intermediate Partnership and MGP holds the 1.0001% managing general partner interest in the Intermediate Partnership.  To determine whether the Intermediate Partnership is a VIE, we considered that since the Intermediate Partnership is structured as a limited partnership with the limited partner 1) not having the ability to remove its general partner and 2) not participating significantly in the operational decisions, the Intermediate Partnership represents a VIE.

We determined that neither the MGP nor ARLP have both the power and the benefits related to Intermediate Partnership.  We then considered which of the two was most closely aligned with the Intermediate Partnership and thus would be designated the primary beneficiary of the Intermediate Partnership for consolidation purposes.  We determined that ARLP was most closely aligned with the Intermediate Partnership and is the primary beneficiary.  We based our determination of alignment on 1) the purpose and design of the Intermediate Partnership which is to a) be the operating subsidiary to ARLP and b) distribute all of its available cash to ARLP to pay its partners and 2) AHGP's common control over ARLP, MGP and the Intermediate Partnership, as discussed in Note 1 – Organization and Presentation, to achieve the aforementioned purpose and design.

The effect of the partnership agreements of ARLP and the Intermediate Partnership and the operating agreement of Alliance Coal (collectively the "Agreements") is that on a quarterly basis 100% of available cash from our operations must be distributed by ARLP to its partners (apart from nominal distributions from the Intermediate Partnership and Alliance Coal to MGP and SGP).  Available cash is determined as defined in the Agreements and represents all cash with the exception of cash reserves (i) for the proper conduct of the business including reserves for future capital expenditures and for anticipated credit needs of the Partnership Group, (ii) to comply with debt obligations or (iii) to provide funds for certain subsequent distributions.  Cash reserves may not be established for the purpose of funding subsequent distributions if the effect would be to prevent ARLP from making the minimum quarterly distributions plus any cumulative distribution arrearage.  MGP, as the managing member of Alliance Coal and the managing general partner of the Intermediate Partnership, is responsible for distributing this cash to ARLP so it can meet its distribution requirements.  As discussed in Note 6 – Long-Term Debt, the Intermediate Partnership's debt covenants place additional restrictions on distributions to ARLP by limiting cash available for distribution from the Intermediate Partnership based on various debt covenants pertaining to the most recent preceding quarter.  MGP does not have the ability, without the consent of the limited partners, to amend the Agreements.

In November 2014, Cavalier Minerals (see Note 7 – Variable Interest Entities), was created to indirectly purchase, through its equity investments in AllDale Minerals, oil and gas mineral interests in various geographic locations within producing basins in the continental U.S.  In February 2017, Alliance Minerals committed to directly (rather than through Cavalier Minerals) invest $30.0 million in AllDale Minerals III, LP ("AllDale III") which was created for similar investment purposes.  We continually review all rights provided to Cavalier Minerals and us by various agreements and continue to conclude all such rights do not provide Cavalier Minerals or us the ability to unilaterally direct any of the activities of AllDale Minerals or AllDale III (collectively, the "AllDale Partnerships") that most significantly impact the economic performance of the AllDale Partnerships.  As such, we account for our ownership interest in the income or loss of the AllDale Partnerships as equity investments and it is so reflected in our condensed consolidated financial statements.  We record equity income or loss based on the AllDale Partnerships' individual distribution structures.  The changes in our aggregate equity investment in the AllDale Partnerships for each of the periods presented were as follows:

NET INCOME OF ARLP PER LIMITED PARTNER UNIT

NET INCOME OF ARLP PER LIMITED PARTNER UNIT

9.NET INCOME OF ARLP PER LIMITED PARTNER UNIT

We utilize the two-class method in calculating basic and diluted earnings per unit ("EPU").  Net income of ARLP is allocated to the general partners and limited partners in accordance with their respective partnership percentages, after giving effect to any special income or expense allocations, including incentive distributions to our managing general partner, the holder of the IDR pursuant to our partnership agreement, which are declared and paid following the end of each quarter. Under the quarterly IDR provisions of our partnership agreement, our managing general partner is entitled to receive 15% of the amount we distribute in excess of $0.1375 per unit, 25% of the amount we distribute in excess of $0.15625 per unit, and 50% of the amount we distribute in excess of $0.1875 per unit.  Our partnership agreement contractually limits our distributions to available cash; therefore, undistributed earnings of the ARLP Partnership are not allocated to the IDR holder.  In addition, outstanding awards under our Long-Term Incentive Plan ("LTIP") and phantom units in notional accounts under our Supplemental Executive Retirement Plan ("SERP") and the MGP Amended and Restated Deferred Compensation Plan for Directors ("Deferred Compensation Plan") include rights to nonforfeitable distributions or distribution equivalents and are therefore considered participating securities.  As such, we allocate undistributed and distributed earnings to these outstanding awards in our calculation of EPU.  The following is a reconciliation of net income of ARLP used for calculating basic earnings per unit and the weighted-average units used in computing EPU for the three months ended March 31, 2017 and 2016:

(1) Diluted EPU gives effect to all dilutive potential common units outstanding during the period using the treasury stock method. Diluted EPU excludes all dilutive potential units calculated under the treasury stock method if their effect is anti-dilutive.  The combined total of LTIP, SERP and Deferred Compensation Plan units of 1,427 and 439 for the three months ended March 31, 2017 and 2016, respectively, were considered anti-dilutive under the treasury stock method.

During the three months ended March 31, 2017, an affiliated entity controlled by Mr. Craft made a capital contribution of $0.8 million to AHGP for the purpose of funding certain general and administrative expenses.  Upon AHGP's receipt of the contribution, it contributed the same to its subsidiary MGP, our managing general partner, which in turn contributed the same to our subsidiary, Alliance Coal.  As provided under our partnership agreement, we made a special allocation to our managing general partner of certain general and administrative expenses equal to its contribution.  Net income of ARLP allocated to the limited partners was not burdened by this expense.

Long-Term Incentive Plan

We have the LTIP for certain employees and officers of MGP and its affiliates who perform services for us.  The LTIP awards are grants of non-vested "phantom" or notional units, also referred to as "restricted units", which upon satisfaction of time and performance-based vesting requirements, entitle the LTIP participant to receive ARLP common units.  Annual grant levels and vesting provisions for designated participants are recommended by the President and Chief Executive Officer of MGP, subject to review and approval of the compensation committee of the MGP board of directors (the "Compensation Committee").  Vesting of all grants outstanding are subject to the satisfaction of certain financial tests, which management currently believes are probable.  Grants issued to LTIP participants are expected to cliff vest on January 1st of the third year following issuance of the grants.  We expect to settle the non-vested LTIP grants by delivery of ARLP common units, except for the portion of the grants that will satisfy tax withholding obligations of LTIP participants.  As provided under the distribution equivalent rights provisions of the LTIP and the terms of the LTIP awards, all non-vested grants include contingent rights to receive quarterly distributions in cash or, in the case of the 2016 and 2017 grants, at the discretion of the Compensation Committee, cash or in lieu of cash, phantom units credited to a bookkeeping account with value, equal to the cash distributions we make to unitholders during the vesting period. 

A summary of non-vested LTIP grants as of and for the three months ended March 31, 2017 is as follows:

	Number of units	Weighted average grant date fair value per unit		Intrinsic value
				(in thousands)
Non-vested grants at January 1, 2017	1,604,748	$	23.19	$	36,027

Vested (1)	(350,516)		40.73
Forfeited	(16,466)		21.22
Non-vested grants at March 31, 2017	1,700,656		19.61		36,819

(1) During the three months ended March 31, 2017, we issued 222,011 unrestricted common units to the LTIP participants.  The remaining vested units were settled in cash to satisfy tax withholding obligations of the LTIP participants.

For the three months ended March 31, 2017 and 2016, our LTIP expense was $2.6 million and $2.9 million, respectively.  The total obligation associated with the LTIP as of March 31, 2017 was $13.4 million and is included in the partners' capital Limited partners-common unitholders line item in our condensed consolidated balance sheets. As of March 31, 2017, there was $19.9 million in total unrecognized compensation expense related to the non-vested LTIP grants that are expected to vest.  That expense is expected to be recognized over a weighted-average period of 1.8 years.

After consideration of the January 1, 2017 vesting and subsequent issuance of 222,011 common units, approximately 2.5 million units remain available under the LTIP for issuance in the future, assuming all grants issued in 2017, 2016 and 2015 and currently outstanding are settled with common units, without reduction for tax withholding, and no future forfeitures occur.   

Supplemental Executive Retirement Plan and Directors Deferred Compensation Plan

We utilize the SERP to provide deferred compensation benefits for certain officers and key employees. All allocations made to participants under the SERP are made in the form of "phantom" ARLP units and SERP distributions will be settled in the form of ARLP common units.  The SERP is administered by the Compensation Committee. 

Our directors participate in the Deferred Compensation Plan. Pursuant to the Deferred Compensation Plan, for amounts deferred either automatically or at the election of the director, a notional account is established and credited with notional common units of ARLP, described in the Deferred Compensation Plan as "phantom" units.  Distributions from the Deferred Compensation Plan will be settled in the form of ARLP common units.

For both the SERP and Deferred Compensation Plan, when quarterly cash distributions are made with respect to ARLP common units, an amount equal to such quarterly distribution is credited to each participant's notional account as additional phantom units.  All grants of phantom units under the SERP and Deferred Compensation Plan vest immediately.

 A summary of SERP and Deferred Compensation Plan activity as of and for the three months ended March 31, 2017 is as follows:

	Number of units	Weighted average grant date fair value per unit		Intrinsic value
				(in thousands)
Phantom units outstanding as of January 1, 2017	494,018	$	29.77	$	11,091
Granted	12,307		23.22
Phantom units outstanding as of March 31, 2017	506,325		29.61		10,962

Total SERP and Deferred Compensation Plan expense was $0.3 million for each of the three months ended March 31, 2017 and 2016.  As of March 31, 2017, the total obligation associated with the SERP and Deferred Compensation Plan was $15.0 million and is included in the partners' capital Limited partners-common unitholders line item in our condensed consolidated balance sheets.

SEGMENT INFORMATION

13.SEGMENT INFORMATION

We operate in the eastern U.S. as a producer and marketer of coal to major utilities and industrial users.  We aggregate multiple operating segments into two reportable segments: Illinois Basin and Appalachia, and we have an "all other" category referred to as Other and Corporate.  Our reportable segments correspond to major coal producing regions in the eastern U.S.  Similar economic characteristics for our operating segments within each of these two reportable segments generally include coal quality, geology, coal marketing opportunities, mining and transportation methods and regulatory issues.  

The Illinois Basin reportable segment is comprised of multiple operating segments, including current operating mining complexes a) Webster County Coal, LLC's Dotiki mining complex, b) Gibson County Coal, LLC's mining complex, which includes the Gibson North (currently idled) and Gibson South mines, c) Warrior Coal, LLC's mining complex, d) River View Coal, LLC's mining complex and e) Hamilton County Coal, LLC’s mining complex.  The Gibson North mine has been idled since the fourth quarter of 2015 in response to market conditions.

The Illinois Basin reportable segment also includes White County Coal, LLC's Pattiki mining complex ("Pattiki"), Hopkins County Coal, LLC's mining complex, which includes the Elk Creek mine, the Pleasant View surface mineable reserves and the Fies underground project, Sebree Mining, LLC's mining complex ("Sebree"), which includes the Onton mine, Steamport, LLC and certain Sebree reserves, CR Services, LLC, CR Machine Shop, LLC, certain properties and equipment of Alliance Resource Properties, ARP Sebree, LLC, ARP Sebree South, LLC and UC Coal, LLC and its subsidiaries, UC Mining, LLC and UC Processing, LLC (collectively "UC Coal").  The Pattiki mine ceased production in December 2016.  The Elk Creek mine depleted its reserves in March 2016 and ceased production on April 1, 2016.  Our Onton mine has been idled since the fourth quarter of 2015 in response to market conditions.  UC Coal equipment assets acquired in 2015 continue to be deployed as needed at various Illinois Basin operating mines.

The Appalachia reportable segment is comprised of multiple operating segments, including the Mettiki mining complex, the Tunnel Ridge, LLC mining complex and the MC Mining, LLC mining complex. The Mettiki mining complex includes Mettiki Coal (WV), LLC's Mountain View mine and Mettiki Coal, LLC's preparation plant.

Other and Corporate includes marketing and administrative activities, ASI and its subsidiary, Matrix Design Group, LLC and its subsidiaries Matrix Design International, LLC and Matrix Design Africa (PTY) LTD ("Matrix Design"), Alliance Design Group, LLC ("Alliance Design") (collectively, the Matrix Design entities and Alliance Design are referred to as the "Matrix Group"), ASI's ownership of aircraft, the Mt.

(1) The elimination column represents the elimination of intercompany transactions and is primarily comprised of sales from the Matrix Group and MAC to our mining operations, coal sales and purchases between operations within different segments, sales of receivables to AROP Funding and insurance premiums paid to Wildcat Insurance.

(2) Revenues included in the Other and Corporate column are primarily attributable to the Matrix Group revenues, Mt. Vernon transloading revenues, administrative service revenues from affiliates, MAC revenues, Wildcat Insurance revenues and brokerage coal sales.

(3) Segment Adjusted EBITDA Expense includes operating expenses, coal purchases and other income. Transportation expenses are excluded as these expenses are passed through to our customers and consequently we do not realize any gain or loss on transportation revenues.  We review Segment Adjusted EBITDA Expense per ton for cost trends.  Results presented for Segment Adjusted EBITDA Expense for the three months ended March 31, 2016 have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as adjustments to Depreciation, depletion and amortization rather than Operating expenses (excluding depreciation, depletion and amortization).

The following is a reconciliation of consolidated Segment Adjusted EBITDA Expense to Operating expenses (excluding depreciation, depletion and amortization):

	Three Months Ended
	March 31,
	2017		2016
	(in thousands)
Segment Adjusted EBITDA Expense	$	261,494	$	263,488
Other income		1,298		91
Operating expenses (excluding depreciation, depletion and amortization)	$	262,792	$	263,579

(4) Segment Adjusted EBITDA 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.  Management therefore is able to focus solely on the evaluation of segment operating profitability as it relates to our revenues and operating expenses, which are primarily controlled by our segments.  Results presented for Segment Adjusted EBITDA for the three months ended March 31, 2016 have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as adjustments to Depreciation, depletion and amortization rather than Operating expenses (excluding depreciation, depletion and amortization).  Consolidated Segment Adjusted EBITDA is reconciled to net income as follows:

The accompanying condensed consolidated financial statements include the accounts and operations of the ARLP Partnership and present the consolidated financial position as of March 31, 2017 and December 31, 2016 and the results of operations, comprehensive income and cash flows for the three months ended March 31, 2017 and 2016 of ARLP, the Intermediate Partnership (a subsidiary of ARLP and a variable interest entity of which ARLP is the primary beneficiary), Alliance Coal (a subsidiary of the Intermediate Partnership and a variable interest entity of which the Intermediate Partnership is the primary beneficiary) and other directly and indirectly wholly- and majority-owned subsidiaries of the Intermediate Partnership and Alliance Coal.  The Intermediate Partnership, Alliance Coal and their wholly- and majority-owned subsidiaries represent virtually all the net assets of the ARLP Partnership.  MGP's interests in both Alliance Coal and the Intermediate Partnership and SGP's 0.01% interest in the Intermediate Partnership are reported as part of the overall two percent general partner interest in the ARLP Partnership.  MGP's IDR in ARLP are also reported with the general partner interest in ARLP.  All intercompany transactions and accounts have been eliminated.  See Note 7 – Variable Interest Entities for more information regarding ARLP's consolidation of the Intermediate Partnership and Alliance Coal.  See Note 9 – Net Income of ARLP Per Limited Partner Unit for more information regarding MGP's IDR in ARLP.

These condensed consolidated financial statements and notes are unaudited. However, in the opinion of management, these financial statements reflect all normal recurring adjustments necessary for a fair presentation of the results for the periods presented.  Results presented for prior periods have been recast to reflect an immaterial reclassification of depreciation, depletion, and amortization capitalized into coal inventory as an adjustment to Depreciation, depletion, and amortization rather than Operating expenses (excluding depreciation, depletion, and amortization).  This reclassification did not impact Total operating expenses,  Income from operations,  Net income,  Net income of ARLP or Basic and diluted net income of ARLP per limited partner unit.  Results for interim periods are not necessarily indicative of results to be expected for the full year ending December 31, 2017.  

These condensed consolidated financial statements and notes are prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim reporting and do not include all of the information normally included with financial statements prepared in accordance with generally accepted accounting principles ("GAAP") of the United States.  These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016.

(4) Segment Adjusted EBITDA 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.  Management therefore is able to focus solely on the evaluation of segment operating profitability as it relates to our revenues and operating expenses, which are primarily controlled by our segments.  Results presented for Segment Adjusted EBITDA for the three months ended March 31, 2016 have been recast to reflect a reclassification of depreciation and depletion capitalized into coal inventory as adjustments to Depreciation, depletion and amortization rather than Operating expenses (excluding depreciation, depletion and amortization).  Consolidated Segment Adjusted EBITDA is reconciled to net income as follows:
