Management Commentary

"The increase in our distribution reflects strong execution across the business and highlights the benefits of Black Stone's diversified mineral and royalty portfolio," said Taylor DeWalch, Co-CEO and President. "Through our focus on mineral acquisitions, development agreements, and active asset management, we continue to advance our differentiated organic growth strategy. We are pleased to increase the distribution while maintaining a prudent level of coverage and a conservative balance sheet as we continue to focus on accretive returns for our unitholders. Improved oil pricing and production contributed to our results during the quarter, and we remain highly encouraged by the long-term outlook for natural gas and increasing activity across our core development areas."

Fowler Carter, Co-CEO and President, added, "As we have previously discussed, we believe the Partnership is at an important inflection point for production and commercial activity. Development under our existing agreements continues to progress, and we have made significant progress toward an agreement covering a new development area, further expanding development opportunities across our Shelby Trough and Haynesville expansion acreage. Combined with continued leasing activity and our ongoing mineral acquisition program, we remain focused on enhancing our development position and supporting long-term production growth."

Quarterly Financial and Operating Results

Production

Black Stone reported mineral and royalty volumes of 32.5 MBoe/d (72% natural gas) for the second quarter of 2026, compared to 35.9 MBoe/d for the first quarter of 2026 and 33.2 MBoe/d for the second quarter of 2025. Production declined from the first quarter primarily due to lower natural gas mineral and royalty volumes in the Haynesville.

Working-interest production was 1.0 MBoe/d for the second quarter of 2026, 1.1 MBoe/d in the first quarter of 2026, and 1.4 MBoe/d for the second quarter of 2025.

Total reported production averaged 33.5 MBoe/d (97% mineral and royalty, 72% natural gas) for the second quarter of 2026, compared to 37.0 MBoe/d and 34.6 MBoe/d for the first quarter of 2026 and the second quarter of 2025, respectively.

Realized Prices, Revenues, and Net Income

The Partnership’s average realized price per Boe, excluding the effect of derivative settlements, was $37.82 for the second quarter of 2026. This is an increase of 7% from $35.30 per Boe in the first quarter of 2026 and a 17% increase from $32.40 in the second quarter of 2025.

Black Stone reported oil and gas revenue of $115.4 million (65% oil and condensate) for the second quarter of 2026, a decrease of 2% from $117.5 million in the first quarter of 2026. Oil and gas revenue in the second quarter of 2025 was $102.0 million.

The Partnership reported a gain on commodity derivative instruments of $26.8 million for the second quarter of 2026, composed of a $8.8 million loss from realized settlements and a non-cash $35.6 million unrealized gain due to the change in value of Black Stone’s derivative positions during the quarter. Black Stone reported a loss of $64.6 million and a gain of $52.8 million on commodity derivative instruments for the first quarter of 2026 and the second quarter of 2025, respectively.

Lease bonus and other income was $6.7 million for the second quarter of 2026. Lease bonus and other income for the first quarter of 2026 and the second quarter of 2025 was $6.4 million and $4.7 million, respectively.

The Partnership reported net income of $106.4 million for the second quarter of 2026, compared to net income of $13.3 million in the preceding quarter. For the second quarter of 2025, the Partnership reported net income of $120.0 million.

Adjusted EBITDA and Distributable Cash Flow

Adjusted EBITDA for the second quarter of 2026 was $91.3 million, which compares to $87.0 million in the first quarter of 2026 and $85.6 million in the second quarter of 2025. Distributable cash flow for the second quarter of 2026 was $80.4 million. For the first quarter of 2026 and the second quarter of 2025, distributable cash flow was $76.5 million and $76.2 million, respectively.

As of June 30, 2026, Black Stone had $1.7 million in cash, with $196.0 million drawn under its credit facility. As of July 31, 2026, the Partnership had $1.9 million in cash, with $168.0 million outstanding under the credit facility. Black Stone is in compliance with all financial covenants associated with its credit facility.

On April 28, 2026, the borrowing base under the credit facility was reaffirmed at $580.0 million and the Partnership elected to maintain total commitments under the credit facility at $375.0 million. The Partnership's next regularly scheduled borrowing base redetermination is set for October 2026.

Second Quarter 2026 Distributions

As previously announced, the Board approved a cash distribution of $0.32 for each common unit attributable to the second quarter of 2026, representing a distribution coverage ratio of approximately 1.18x. The distribution will be payable on August 13, 2026, to unitholders of record as of the close of business on August 6, 2026.

Activity Update

Development Activity

At the end of the second quarter, Adamas Energy (formerly Aethon Energy, "Adamas") was operating two rigs on Black Stone's Angelina and San Augustine acreage in the Shelby Trough. Adamas successfully turned to sales 4 gross (0.4 net) wells in July 2026. Adamas’s development program remains on track with the development agreements, with a total of 14 wells spud in the previous program year that ended on June 30, 2026. Of these wells, 6 gross (0.6 net) have turned to sales as of July 31, 2026, and 8 gross (0.7 net) are expected to turn to sales during the remainder of 2026. Adamas expects to drill 17 wells in the next program year that began in July 2026.

The Partnership's agreement with Revenant Energy ("Revenant") covers 270,000 gross acres in which it currently controls approximately 122,000 undeveloped net acres. Under the original agreement, Revenant was obligated to drill a minimum of 6 wells in 2026, increasing annually to a minimum of 25 wells per year by 2030. The Partnership also secured a non-operated working interest partner for the development. In November 2025, the agreement was amended to maintain the original 6-well commitment for 2026 and convert future commitments to completed gross lateral-foot targets at one well per 7,000 lateral feet, allowing longer laterals while keeping overall development levels unchanged. In May 2026, the agreement was amended to reduce the Program Year 1 drilling commitment to 4 wells following the well control incident in April 2026 affecting one of the two wells spud in the first quarter of 2026. The amendment also revised the gross lateral-foot commitments applicable to subsequent program years and released approximately 40,000 gross acres from the development program. Development activity continued during the second quarter of 2026, with Revenant spudding two additional wells.

In November 2025, Black Stone entered into a 220,000 gross acre development agreement with Caturus Energy, LLC ("Caturus"), which aims to push the Shelby Trough westward towards the Western Haynesville. Activity will begin with approximately 2 gross (0.2 net) wells in the second half of 2026 and ramp to approximately 12 gross (0.8 net) wells annually by 2031, supported by minimum annual lateral-foot requirements, all net to Black Stone's interest. In addition to the 2 gross development wells in 2026, Caturus is currently drilling a pilot well in Cherokee County, consistent with the terms of the agreement.

In the Permian Basin, Blue Arrow Operating is in progress on a development of 25 gross (1.9 net) wells in the southern Delaware Basin. Three wells were turned to sales during the quarter with the remaining expected to come online in the second half of 2026 and first half of 2027.

Acquisition Activity

The Partnership continues to acquire bolt-on acreage in multiple contractual development programs with significant inventory at high net interests across San Augustine, Nacogdoches, Angelina, Cherokee, Houston, and Trinity counties.

In the second quarter of 2026, Black Stone acquired $48.7 million of additional (primarily non-producing) mineral and royalty interests. From September 2023 through the end of June 2026, the Partnership has completed $299.7 million of mineral and royalty acquisitions, primarily in the expanding Shelby Trough area. Black Stone’s commercial strategy going forward includes the continuation of meaningful, targeted mineral and royalty acquisitions to complement the Partnership's existing positions.

¹As a mineral-and-royalty-interest owner, Black Stone Minerals is often provided insufficient and inconsistent data on natural gas liquid ("NGL") volumes by its operators. As a result, the Partnership is unable to reliably determine the total volumes of NGLs associated with the production of natural gas on its acreage. Accordingly, no NGL volumes are included in reported production; however, revenue attributable to NGLs is included in natural gas revenue and the calculation of realized prices for natural gas.

Non-GAAP Financial Measures

Adjusted EBITDA and Distributable Cash Flow are supplemental non-GAAP financial measures used by Black Stone’s management and external users of the Partnership’s financial statements such as investors, research analysts, and others, to assess the financial performance of its assets and its ability to sustain distributions over the long term without regard to financing methods, capital structure, or historical cost basis.

The Partnership defines Adjusted EBITDA as net income (loss) before interest expense, income taxes, and depreciation, depletion, and amortization adjusted for impairment of oil and natural gas properties, if any, accretion of asset retirement obligations, seismic data acquisition costs, non-cash equity-based compensation, unrealized gains and losses on commodity derivative instruments, and gains and losses on sales of assets, if any. Black Stone defines Distributable Cash Flow as Adjusted EBITDA plus or minus amounts for certain non-cash operating activities, cash interest expense, distributions to preferred unitholders, and restructuring charges, if any.

Beginning with the three months and year ended December 31, 2025, the Partnership revised its definition of Adjusted EBITDA to exclude seismic data acquisition costs, which are included in Exploration expense on the Partnership’s consolidated statements of operations. Comparative amounts for the three and six months ended June 30, 2025, for each of Adjusted EBITDA and Distributable Cash Flow have been recast to conform to the current period presentation. Management believes this revised definition enhances comparability between periods and reflects the Partnership’s view of seismic data acquisition costs as investments that support the long-term development and value of its mineral and royalty interests.

Adjusted EBITDA and Distributable Cash Flow should not be considered an alternative to, or more meaningful than, net income (loss), income (loss) from operations, cash flows from operating activities, or any other measure of financial performance presented in accordance with generally accepted accounting principles ("GAAP") in the United States as measures of the Partnership’s financial performance.

Adjusted EBITDA and Distributable Cash Flow have important limitations as analytical tools because they exclude some but not all items that affect net income (loss), the most directly comparable U.S. GAAP financial measure. The Partnership’s computation of Adjusted EBITDA and Distributable Cash Flow may differ from computations of similarly titled measures of other companies.
