Management Commentary

Thomas L. Carter, Jr., Black Stone Minerals' Chairman, Chief Executive Officer and President, commented, "We previously announced the Company's plan to decrease the first quarter 2024 distribution. We remain focused on disciplined capital management and staying the course of targeted, grass-roots mineral acquisitions that are accretive to our mineral positions in strategic basins. Because of decisions made by the Company in the past four years, we are well-positioned to stay focused on long-term decision-making, which we view as one of our most significant strategic advantages we have relative to our peers. With a comprehensive strategy focused on capital discipline, maintaining a strong balance sheet, thoughtful hedging and commercial strategy centered on organic growth, we are able to weather commodity price cycles for longer periods of time and stay focused on decisions that are best for the Company in the long term."

Quarterly Financial and Operating Results

Production

Black Stone Minerals reported mineral and royalty volumes of 38.1 MBoe/d (75% natural gas) for the first quarter of 2024, compared to 38.9 MBoe/d for the fourth quarter of 2023 and 36.8 MBoe/d for the first quarter of 2023. The decrease from the fourth quarter of 2023 was primarily driven by declines in the Permian.

Working-interest production for the first quarter of 2024 was 2.2 MBoe/d, representing the same volume generated in the quarter ended December 31, 2023, and a decrease of 8% from the quarter ended March 31, 2023. The continued decline year over year in working-interest volumes is consistent with the Company's decision to farm out its working-interest participation to third-party capital providers.

Total reported production averaged 40.3 MBoe/d (95% mineral and royalty, 75% natural gas) for the first quarter of 2024, compared to 41.1 MBoe/d and 39.3 MBoe/d for the quarters ended December 31, 2023 and March 31, 2023, respectively.

Realized Prices, Revenues, and Net Income

The Company's average realized price per Boe, excluding the effect of derivative settlements, was $30.87 for the quarter ended March 31, 2024. This is a decrease of 12% from $35.03 per Boe in the fourth quarter of 2023 and an 8% decrease from $33.47 in the first quarter of 2023.

Black Stone reported oil and gas revenue of $113.2 million (63% oil and condensate) for the first quarter of 2024, a decrease of 15% from $132.6 million in the fourth quarter of 2023. Oil and gas revenue in the first quarter of 2023 was $118.3 million.

The Company reported a loss on commodity derivative instruments of $11.3 million for the first quarter of 2024, composed of a $13.8 million gain from realized settlements and a non-cash $25.1 million unrealized loss due to the change in value of Black Stone's derivative positions during the quarter. Black Stone reported a gain of $54.5 million and a gain of $52.3 million on commodity derivative instruments for the quarters ended December 31, 2023 and March 31, 2023, respectively.

Lease bonus and other income was $3.5 million for the first quarter of 2024. Lease bonus and other income for the quarters ended December 31, 2023 and March 31, 2023 was $3.8 million and $4.0 million, respectively.

The Company reported net income of $63.9 million for the quarter ended March 31, 2024, compared to net income of $147.6 million in the preceding quarter. For the quarter ended March 31, 2023, the Company reported net income of $134.4 million.

Adjusted EBITDA and Distributable Cash Flow

Adjusted EBITDA for the first quarter of 2024 was $104.1 million, which compares to $125.5 million in the fourth quarter of 2023 and $109.9 million in the first quarter of 2023. Distributable cash flow for the quarter ended March 31, 2024 was $96.4 million. For the quarters ended December 31, 2023 and March 31, 2023, distributable cash flow was $119.1 million and $104.1 million, respectively.

Financial Position and Activities

As of March 31, 2024, Black Stone Minerals had $40.5 million in cash, with no amounts drawn under its credit facility. At the beginning of May, the Company had approximately $89 million in cash, and no debt was outstanding under the credit facility.

Subsequent to quarter-end, Black Stone's borrowing base under the credit facility was reaffirmed at $580 million, and total commitments under the credit facility were maintained at $375 million. Black Stone is in compliance with all financial covenants associated with its credit facility.

First Quarter 2024 Distributions

As previously announced, the Board approved a cash distribution of $0.375 for each common unit attributable to the first quarter of 2024. The quarterly distribution coverage ratio attributable to the first quarter of 2024 was approximately 1.22x. The distribution will be paid on May 17, 2024 to unitholders of record as of the close of business on May 10, 2024.

Activity Update

Rig Activity

As of March 31, 2024, Black Stone had 78 rigs operating across its acreage position, an increase relative to the 63 rigs on the Company's acreage as of December 31, 2023, and in line with the 78 rigs operating on the Company's acreage as of March 31, 2023. The higher rig count at the end of the first quarter compared to the fourth quarter was driven primarily by an increase in activity in the Midland/Delaware and was partially offset by a decrease in the Haynesville/Bossier.

Shelby Trough Development Update

A significant portion of Shelby Trough development in recent years has been performed by Aethon Energy ("Aethon") under the two Joint Exploration Agreements ("JEAs") between the Company and Aethon. The JEAs outline Aethon's development obligations and other rights and obligations of each party related to the Company's core mineral positions in San Augustine and Angelina counties in East Texas.

As announced on December 22, 2023, Black Stone received notice that Aethon was exercising the "time-out" provisions under these JEAs. When natural-gas prices fall below specified thresholds, Aethon may elect to temporarily suspend its drilling obligations for up to nine consecutive months and a maximum of 18 total months in any 48-month period. Aethon has not previously invoked the time-out provisions under the JEAs. We continue working closely with Aethon to finalize development plans going forward and assess the effect of the temporary suspension of drilling obligations, and we are analyzing the potential impacts to the Company on an ongoing basis.

In April 2024, Aethon began curtailing production volumes on a small number of producing wells. This temporary decrease is expected to amount to approximately 800 Boe/d. Additionally, Aethon has indicated that it intends to curtail these wells and delay the initial production of an additional 10 wells until the second half of the year, when natural gas prices are forecast to improve.

Austin Chalk Update

Black Stone has entered into agreements with multiple operators to drill wells in the areas of the Austin Chalk in East Texas, where the Company has significant acreage positions. The results of the test program in the Brookeland Field demonstrated that modern completion technology has the potential to improve production rates and increase reserves when compared to the vintage, unstimulated wells in the Austin Chalk formation. To date, 30 wells with modern completions are being produced in the field.

Acquisition Activity

Black Stone's commercial strategy since 2021 has been focused on attracting capital and securing drilling commitments on minerals already owned by the Company. Management made the decision to expand this growth strategy by adding to the Company's mineral portfolio through strategic, targeted efforts primarily in the Gulf Coast region. In the first quarter of 2024 Black Stone acquired additional non-producing mineral and royalty interests totaling $23.0 million. Since March 31, 2024, the Company has acquired an additional $12.3 million of non-producing mineral and royalty interests, resulting in total acquisitions of $49.9 million since September 2023. Black Stone's commercial strategy going forward includes the continuation of meaningful, targeted mineral and royalty acquisitions to complement our existing positions.

Guidance Update

Because the Company expects continued pressure on natural gas prices will result in production curtailments and delays in drilling and completion of new wells, Black Stone's total production guidance is being lowered to a range of 38.5 MBoe/d to 40.5 MBoe/d, from the previously disclosed range of 40.0 MBoe/d to 42.0 MBoe/d.

Update to Hedge Position

Black Stone has commodity derivative contracts in place covering portions of its anticipated production for 2024 and 2025. The Company's hedge position as of May 3, 2024 is summarized in the following tables:

More detailed information about the Company's existing hedging program can be found in the Quarterly Report on Form 10-Q for the first quarter of 2024, which is expected to be filed on or around May 7, 2024.

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 Company's financial statements such as investors, research analysts, and others, to assess the financial performance of its assets and ability to sustain distributions over the long term without regard to financing methods, capital structure, or historical cost basis.

The Company 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, unrealized gains and losses on commodity derivative instruments, non-cash equity-based compensation, 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.

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 Company'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 Company's computation of Adjusted EBITDA and Distributable cash flow may differ from computations of similarly titled measures of other companies.
