For Immediate Release
 
Black Stone Minerals, L.P. Announces Fourth Quarter and Full Year 2021 Results;
Provides Guidance for 2022

 
HOUSTON--(BUSINESS WIRE) - Black Stone Minerals, L.P. (NYSE: BSM) (“Black Stone Minerals,” “Black Stone,” or “the Company”) today announces its financial and operating results for the fourth quarter and full year of 2021 and provides guidance for 2022.

Fourth Quarter 2021 Highlights

Mineral and royalty production for the fourth quarter of 2021 equaled 35.2 MBoe/d, an increase of 7% over the prior quarter; total production, including working interest volumes, was 39.1 MBoe/d for the quarter
Net income and Adjusted EBITDA for the quarter were $134.2 million and $77.6 million, respectively
Distributable cash flow was $71.3 million for the fourth quarter, resulting in distribution coverage for all units of 1.3x based on the announced cash distribution of $0.27 per unit
Total debt at the end of the quarter was $89 million; total debt to trailing twelve-month Adjusted EBITDA was 0.3x at year-end


Full Year Financial and Operational Highlights

Mineral and royalty volumes in 2021 decreased 2% over the prior year to average 32.9 MBoe/d; full year 2021 production was 38.0 MBoe/d
Reported 2021 net income and Adjusted EBITDA of $182.0 million and $292.5 million, respectively
Increased cash distributions by 70% from $0.555 per unit attributable to the full year 2020 to $0.945 per unit attributable to the full year 2021
Reduced total outstanding debt by $32 million during 2021


Management Commentary

Thomas L. Carter, Jr., Black Stone Minerals’ Chief Executive Officer and Chairman, commented, “We posted another solid quarter of operational and financial results, as activity levels across much of our acreage continued to improve. The robust cash flows for the fourth quarter, combined with a healthy outlook for 2022 and our low debt levels, allowed for another increase in our distribution per unit. Our asset base is well-situated to benefit from increasing producer activity in key basins, including our significant exposure to the Haynesville Shale as the best-positioned play to support the growing demand for natural gas exports to the global LNG market. Against this backdrop, we remain focused on promoting our undeveloped minerals to drive volume growth while limiting our capital requirements.”



Quarterly Financial and Operating Results

Production

Black Stone Minerals reported mineral and royalty volumes of 35.2 MBoe/d (70% natural gas) for the fourth quarter of 2021, compared to 33.0 MBoe/d for the third quarter of 2021. Mineral and royalty production was 32.0 MBoe/d for the fourth quarter of 2020.

Working interest production for the fourth quarter of 2021 was 3.9 MBoe/d, and represents a decrease of 22% from the 5.1 MBoe/d for the quarter ended September 30, 2021 and a decrease of 44% from the 7.0 MBoe/d for the quarter ended December 31, 2020. The year-over-year decline in working interest production is consistent with the Company's decision to farm out its working-interest participation to third-party capital providers.




Total reported production averaged 39.1 MBoe/d (90% mineral and royalty, 71% natural gas) for the fourth quarter of 2021. Total production was 38.0 MBoe/d and 39.0 MBoe/d for the quarters ended September 30, 2021 and December 31, 2020, respectively.


Realized Prices, Revenues, and Net Income

The Company’s average realized price per Boe, excluding the effect of derivative settlements, was $44.12 for the quarter ended December 31, 2021. This is an increase of 14% from $38.60 per Boe for the third quarter of 2021 and a 99% increase compared to $22.21 for the fourth quarter of 2020.

Black Stone reported oil and gas revenue of $158.9 million (48% oil and condensate) for the fourth quarter of 2021, an increase of 18% from $135.1 million in the third quarter of 2021. Oil and gas revenue in the fourth quarter of 2020 was $79.7 million.

The Company reported a gain on commodity derivative instruments of $18.4 million for the fourth quarter of 2021, composed of a $56.9 million loss from realized settlements and a non-cash $75.3 million unrealized gain due to the change in value of Black Stone’s derivative positions during the quarter. Black Stone reported a loss on commodity derivative instruments of $77.6 million and $3.6 million for the quarters ended September 30, 2021 and December 31, 2020, respectively.

Lease bonus and other income was $2.1 million for the fourth quarter of 2021, primarily related to leasing activity in the Permian Basin and Gulf Coast plays, in addition to proceeds from surface use waivers associated with new solar developments. Lease bonus and other income for the quarters ended September 30, 2021 and December 31, 2020 was $2.3 million and $1.4 million, respectively.

There was no impairment for the quarters ended December 31, 2021, September 30, 2021, and December 31, 2020.

The Company reported net income of $134.2 million for the quarter ended December 31, 2021, compared to net income of $16.2 million in the preceding quarter. For the quarter ended December 31, 2020, net income was $30.3 million.

Adjusted EBITDA and Distributable Cash Flow

Adjusted EBITDA for the fourth quarter of 2021 was $77.6 million, which compares to $76.5 million in the third quarter of 2021 and $72.3 million in the fourth quarter of 2020. Distributable cash flow for the quarter ended December 31, 2021 was $71.3 million. For the quarters ended September 30, 2021 and December 31, 2020, distributable cash flow was $70.2 million and $65.9 million, respectively.

2021 Proved Reserves

Estimated proved oil and natural gas reserves at year-end 2021 were 59.8 MMBoe, an increase of 7% from 56.0 MMBoe at year-end 2020, and were approximately 68% natural gas and 94% proved developed producing. The standardized measure of discounted future net cash flows was $972.1 million at the end of 2021, as compared to $493.5 million at year-end 2020.

Netherland, Sewell and Associates, Inc., an independent, third-party petroleum engineering firm, evaluated Black Stone Minerals’ estimate of its proved reserves and PV-10 at December 31, 2021. These estimates were prepared using reference prices of $66.55 per barrel of oil and $3.60 per MMBTU of natural gas in accordance with the applicable rules of the Securities and Exchange Commission (as compared to prompt month prices of $91.07 per barrel of oil and $4.43 per MMBTU of natural gas as of February 18, 2022). These prices were adjusted for quality and market differentials, transportation fees, and, in the case of natural gas, the value of natural gas liquids. A reconciliation of proved reserves is presented in the summary financial tables following this press release.

Financial Position and Activities

As of December 31, 2021, Black Stone Minerals had $8.9 million in cash and $89.0 million outstanding under its credit facility. The Company paid down $10 million of debt during the fourth quarter of 2021 and $32 million of debt during the full year. The ratio of total debt at year-end to 2021 Adjusted EBITDA was 0.3x. The Company’s borrowing base at December 31, 2021 was $400 million, and the Company's next regularly scheduled borrowing base redetermination is set for April 2022. Black Stone is in compliance with all financial covenants associated with its credit facility.

As of February 18, 2022, $58.0 million was outstanding under the credit facility and the Company had $8.7 million in cash.

During the fourth quarter of 2021, the Company made no repurchases of units under the Board-approved $75 million unit repurchase program.



Fourth Quarter 2021 Distributions

As previously announced, the Board approved a cash distribution of $0.27 for each common unit attributable to the fourth quarter of 2021. The quarterly distribution coverage ratio attributable to the fourth quarter of 2021 was approximately 1.3x. These distributions will be paid on February 23, 2022 to unitholders of record as of the close of business on February 16, 2022.

Activity Update

Rig Activity

As of December 31, 2021, Black Stone had 95 rigs operating across its acreage position, a 61% increase to rig activity on the Company's acreage as of September 30, 2021 and more than twice the 38 rigs operating on the Company's acreage as of December 31, 2020. Black Stone believes its substantial natural gas-weighted asset positions, particularly those in and around the Gulf Coast, are well-situated to benefit from the expected continued increase in demand for LNG exports from the United States. The U.S. Energy Information Administration (“EIA”) estimates that U.S. LNG exports averaged 11.2 billion cubic feet per day (Bcf/d) in January 2022, up from 10.4 Bcf/d in the fourth quarter of 2021, supported by large price differences between the Henry Hub price in the United States and spot prices in Europe and Asia. The EIA expects high levels of U.S. LNG exports to continue into 2022, averaging 16% above 2021 levels. The EIA forecast reflects the assumption that global natural gas demand remains strong and that expected additional U.S. LNG export capacity comes online.

Shelby Trough Development Update

In Angelina County, Texas, two wells are currently producing under Black Stone’s development agreement with Aethon Energy (“Aethon”), and another eight wells are being drilled or completed. Aethon is currently drilling three wells under the separate development agreement covering San Augustine County, Texas.

Shelby Trough Farmout Update

On December 29, 2021, Black Stone entered into a farmout agreement with Azul-SA, LLC ("Azul") covering certain Haynesville and Bossier shale acreage in San Augustine County, Texas subject to the Aethon development agreement (the "Azul Farmout"). Under the terms of the Azul Farmout, Azul will earn 20% of the Partnership's working interest in the partitioned acreage from XTO (up to a maximum of 10% on an 8/8ths basis) and 50% of the Partnership's working interest in other areas (up to a maximum of 12.5% on an 8/8ths basis) in wells drilled and operated by Aethon in accordance with the development agreement. The Partnership will receive an ORRI before payout and an increased ORRI after payout on all wells drilled under the Azul Farmout. As of December 31, 2021, three wells have been spud in the contract area subject to the Azul Farmout.

Austin Chalk Update

Black Stone has entered into agreements with multiple operators to drill wells using advanced fracturing and completion techniques in the areas of the Austin Chalk in East Texas where the Company has significant acreage positions. Five wells have been drilled and turned to sales, and another two wells are in various stages of drilling or completion under these agreements. Early results from these wells, while showing some variability, demonstrate that higher-intensity completions can significantly improve well performance relative to prior generation completion technology and the performance of unstimulated wells.

G&A - TOTAL ($MM)
$48.7$49 - $53
DD&A ($/Boe)
$4.39$4.25 - $4.50


Black Stone expects royalty production to be consistent with or decline slightly in 2022 relative to full year 2021 levels. Factors influencing the production outlook include the expectation of increased producer activity in the Louisiana Haynesville / Bossier and West Texas Midland / Delaware plays, offset by the natural decline in producing wells in the Shelby Trough before activity from the development agreements with Aethon in that area is expected to fully ramp up over the next two years.

Working interest production is expected to decline in 2022 as a result of Black Stone's decision in 2017 to farm-out participation in its working interest opportunities.

The Partnership expects general and administrative expenses to be slightly higher in 2022 as a result of selective hires made to enhance Black Stone’s ability to evaluate and market its undeveloped acreage positions to potential operators.

1 As 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 Company 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 our 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 Company's financial statements such as investors, research analysts, and others, to assess the financial performance of its assets and our 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, 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. Black Stone defines Distributable cash flow as Adjusted EBITDA plus or minus amounts for certain non-cash operating activities, cash interest expense, and restructuring charges.
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.
