​ 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 and completed its initial public offering on August 19, 1999 when it acquired substantially all of the coal production and marketing assets of Alliance Resource Holdings, Inc., a Delaware corporation ("ARH"), and its subsidiaries. We are managed by our general partner, MGP, a Delaware limited liability company which holds a non-economic general partner interest in ARLP. Alliance GP, LLC ("AGP"), which is indirectly wholly owned by Mr. Craft, is the direct owner of MGP. ​ Oil & Gas Acquisitions ​ Boulders ​ On October 13, 2021, we acquired approximately 1,480 oil & gas net royalty acres in the Delaware Basin from Boulders Royalty Corp. ("Boulders") for a purchase price of $31.0 million (the "Boulders Acquisition"). ​ Belvedere ​ On September 9, 2022, we acquired approximately 394 oil & gas net royalty acres in the Delaware Basin from Belvedere Operating, LLC ("Belvedere") for a purchase price of $11.4 million (the "Belvedere Acquisition"). ​ Jase ​ On October 26, 2022, we acquired approximately 3,928 oil & gas net royalty acres in the Midland and Delaware Basins from Jase Minerals, LP ("Jase") for a purchase price of $81.2 million (the "Jase Acquisition"). ​ The Boulders, Belvedere and Jase Acquisitions enhanced our ownership position in the Permian Basin and furthered our business strategy to grow our Oil & Gas Royalties segment through accretive acquisitions. See Note 3 – Acquisitions for more information. We now hold approximately 61,400 net royalty acres in premier oil & gas resource plays including previous acquisitions and our investment in AllDale Minerals III, LP ("AllDale III"). ​ Change in Tax Status ​ On March 15, 2022, Alliance Minerals changed its federal income tax status from a pass-through entity to a taxable entity via a "check the box" election (the "Tax Election"), which became effective January 1, 2022. This election for Alliance Minerals is anticipated to reduce the total income tax burden on our oil & gas royalties, as Alliance Minerals will pay entity-level taxes at corporate tax rates which are anticipated to be favorable to our unitholders. For more information on the Tax Election please see Note 9 – Income Taxes. ​ New Venture Investments ​ Francis ​ On April 5, 2022, we made a $20 million convertible note investment in Francis Renewable Energy, LLC ("Francis"). Francis currently is active in the installation, management and operation of metered-for-fee, public-access electric vehicle ("EV") charging stations. Francis also develops and constructs EV charging stations for third-party customers. Our investment in Francis furthers our business strategy to develop strategic relationships and invest in attractive opportunities. For more information on this investment, please see Note 13 – Variable Interest Entities. ​ Infinitum ​ On April 29, 2022, we purchased $32.6 million of Series D Preferred Stock in Infinitum Electric, Inc. ("Infinitum"), a Texas-based startup developer and manufacturer of electric motors featuring printed circuit board stators which have the potential to result in motors that are smaller, lighter, quieter, more efficient and capable of operating at a fraction of the carbon footprint of conventional electric motors. On November 2, 2022, we purchased an additional $9.4 million of Series D Preferred Stock in Infinitum. The preferred stock provides for non-cumulative dividends when and if declared by Infinitum's board of directors. Each share is convertible, at any time, at our option, into shares of common stock of Infinitum. Our investment in Infinitum furthers our business strategy to develop strategic relationships and invest in attractive opportunities. For more information on this investment, please see Note 14 – Investments. ​ NGP ETP IV ​ On June 2, 2022, we committed to purchase $25.0 million of limited partner interests in NGP ETP IV, L.P. ("NGP ETP IV"), a private equity fund sponsored by NGP Energy Capital Management, LLC ("NGP"). NGP ETP IV focuses on investments that are part of the global transition toward a lower carbon economy by partnering with top-tier management teams and investing growth equity in companies that drive or enable the growth of renewable energy, the electrification of our economy or the efficient use of energy. For more information on this investment, please see Note 13 – Variable Interest Entities. ​ Presentation ​ The consolidated financial statements include the accounts and operations of the ARLP Partnership and present our financial position as of December 31, 2022 and 2021, and results of our operations, comprehensive income, cash flows and changes in partners' capital for each of the three years in the period ended December 31, 2022.
