Business Description and Basis of Presentation [Text Block]

1.	Business and Basis of Presentation

Description of the Business

Dorchester Minerals, L.P. (the “Partnership”) is a publicly traded Delaware limited partnership that commenced operations on January 31, 2003. Our business may be described as the acquisition, ownership and administration of Royalty Properties (which consist of producing and nonproducing mineral, royalty, overriding royalty, net profits, and leasehold interests located in 594 counties and parishes in 28 states (“Royalty Properties”)) and net profits overriding royalty interests (referred to as the “Net Profits Interest”, or “NPI”).

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Partnership have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The unaudited consolidated financial statements do not include all of the disclosures required for complete annual financial statements prepared in conformity with U.S. GAAP. Therefore, the accompanying unaudited consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and notes thereto included in the Partnership’s Annual Report. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal and recurring adjustments unless indicated otherwise) that are, in the opinion of management, necessary for the fair presentation of our financial position and operating results for the interim period. Interim period results are not necessarily indicative of the results for the calendar year. Per unit information is calculated by dividing the income or loss applicable to holders of the Partnership’s common units by the weighted average number of units outstanding. The Partnership has no potentially dilutive securities and, consequently, basic and diluted income per unit do not differ.

The unaudited consolidated financial statements include the accounts of the Partnership and its wholly-owned subsidiaries Dorchester Minerals Oklahoma LP, Dorchester Minerals Oklahoma GP, Inc., Maecenas Minerals LLP, Dorchester-Maecenas GP LLC, The Buffalo Co., A Limited Partnership, DMLPTBC GP LLC, and DMLP Terra Firma LLC. All significant intercompany balances and transactions have been eliminated in consolidation.

Certain amounts in the prior‑period condensed consolidated financial statements have been reclassified to conform to the current‑period presentation. Management believes these reclassifications enhance the clarity and consistency of the financial statement presentation. These are presentation only reclassifications and had no effect on total assets, total liabilities, shareholders’ equity, net income, or cash flows for any periods presented.

3.	Acquisitions for Common Units

On August 29, 2025, pursuant to a non-taxable contribution and exchange agreement with multiple unrelated third parties, the Partnership acquired mineral interests totaling approximately 3,050 net royalty acres located in Adams County, Colorado in exchange for 915,694 common units representing limited partnership interests in the Partnership valued at $23.0 million and issued pursuant to the Partnership’s registration statement on Form S-4. We believe that the acquisition is considered complementary to our business. The transaction was accounted for as an acquisition of assets under U.S. GAAP. Accordingly, the cost of the acquisition was allocated on a relative fair value basis and transaction costs were capitalized as a component of the cost of the assets acquired. Oil and natural gas properties, at cost, on the consolidated balance sheet as of December 31, 2025 includes $19.7 million of net capitalized costs attributable to proved oil and natural gas properties acquired in the transaction.

On September 30, 2024, pursuant to a non-taxable contribution and exchange agreement with West Texas Minerals LLC, a Delaware limited liability company, Carrollton Mineral Partners, LP, a Texas limited partnership, Carrollton Mineral Partners Fund II, LP, a Texas limited partnership, Carrollton Mineral Partners III, LP, a Texas limited partnership, Carrollton Mineral Partners III-B, LP, a Texas limited partnership, Carrollton Mineral Partners IV, LP, a Texas limited partnership, CMP Permian, LP, a Texas limited partnership, CMP Glasscock, LP, a Texas limited partnership, and Carrollton Royalty, LP, a Texas limited partnership, the Partnership acquired mineral, royalty, and overriding royalty interests in producing and non-producing oil and natural gas properties representing approximately 14,225 net mineral acres located in 14 counties across New Mexico and Texas in exchange for 6,721,144 common units representing limited partnership interests in the Partnership valued at $202.6 million and issued pursuant to the Partnership’s registration statements on Form S-4. We believe that the acquisition is considered complementary to our business. The transaction was accounted for as an acquisition of assets under U.S. GAAP. Accordingly, the cost of the acquisition was allocated on a relative fair value basis and transaction costs were capitalized as a component of the cost of the assets acquired. Final settlement net cash received, net of capitalized transaction costs paid, of $1.9 million is included in net cash contributed in acquisitions on the consolidated statement of cash flows for the three months ended March 31, 2025.

Segment Reporting [Text Block]

6.	Segment Reporting

The Partnership operates in a single operating and reportable segment. The Partnership’s Chief Executive Officer (“CEO”) has been determined to be the chief operating decision maker of the Partnership. The CEO uses net income to assess financial performance and allocate resources on a consolidated basis. The CEO manages and evaluates the results of the Partnership on a consolidated basis, and net income is used to evaluate key operating decisions, such as making strategic acquisitions, determining transaction structures to capitalize on the development of the properties underlying our mineral interests, and allocating resources for general and administrative expenditures. Disaggregated operating revenues of the Partnership’s single segment and all significant segment expenses are presented separately on the Partnership’s Consolidated Income Statements. There are no other significant segment expenses or other segment items that would require disclosure.

The entire disclosure for segment reporting.

4.	Commitments and Contingencies

Our Partnership and Dorchester Minerals Operating LP, a Delaware limited partnership owned directly and indirectly by our General Partner (the “Operating Partnership”), are involved in legal and/or administrative proceedings arising in the ordinary course of their businesses, none of which have predictable outcomes and none of which are believed to have any significant effect on consolidated financial position, cash flows, or operating results. During the first quarter of 2026, our Partnership and the Operating Partnership entered into a settlement and mutual release agreement with unrelated third parties resolving ordinary course litigation affecting certain leasehold in Midland County, Texas, which is owned by the Operating Partnership and subject to the NPI. The Operating Partnership received proceeds of $15.5 million, which will be included in the calculation of the April 2026 NPI payment.
