Management Commentary

Thomas L. Carter, Jr., Black Stone Minerals’ President, Chief Executive Officer, and Chairman commented, "Black Stone had another very good quarter led by record production volumes and strong lease bonus income. We've accomplished a lot in the first half of 2017 that sets the Partnership up well for the remainder of 2017 and beyond. We have reduced future capital obligations through our working interest farmout, successfully acquired new acreage in the Permian Basin and Haynesville/Bossier Shales, and taken concrete steps to drive increased drilling activity on our core East Texas mineral acreage. These initiatives, combined with the strength of our legacy minerals business, support our confidence in the distribution growth potential at Black Stone, as evidenced by the increased distributions we announced today for both our common and subordinated unitholders."

Quarterly Financial and Operating Results

Production

Black Stone Minerals reported average production of 37.3 MBoe/d for the second quarter of 2017, 76% of which is natural gas and 57% of which is attributable to mineral and royalty interests. This represents an increase of 18% over average production of 31.6 MBoe/d for the corresponding period in 2016 and an increase of 5% over the first quarter of 2017 production levels.

Realized Prices, Revenues, and Net Income

The Partnership’s average realized price per Boe, excluding the effect of derivative settlements, was $25.67 for the quarter ended June 30, 2017. This represents a 7% decrease from the preceding quarter and an increase of 31% from $19.55 per Boe for the quarter ended June 30, 2016.

Black Stone Minerals reported oil and gas revenues of $87.2 million for the second quarter of 2017, an increase of 55% from $56.2 million for the second quarter of 2016 that reflects improved commodity prices and higher production volumes between the periods. Oil and gas revenue in the first quarter of 2017 was $88.2 million.

Gain on commodity derivative instruments was $22.0 million in the second quarter of 2017, which comprises a $3.1 million gain from realized settlements and an $18.9 million unrealized gain due to the change in value of the Partnership’s derivative positions during the quarter. In the second quarter of 2016, the Partnership reported a loss on commodity derivative instruments of $30.7 million that included a large unrealized loss for the period.

Leasing in the Bakken/Three Forks, Permian, and Austin Chalk drove lease bonus and other income to $11.4 million for the second quarter of 2017, a slight decrease from the $15.1 million in lease bonus and other income from the same period last year. Through the first half of 2017, the Partnership has reported $25.0 million in lease bonus and other income compared to $16.5 million for the same period in 2016.

The Partnership reported net income of $54.2 million for the quarter ended June 30, 2017, compared to a net loss of $20.8 million in the corresponding period in 2016.

Financial Position

As of June 30, 2017, the Partnership had $7.5 million in cash and $393.0 million outstanding under its credit facility. The borrowing base currently stands at $550.0 million following a $50.0 million increase in its most recent semi-annual redetermination in April of 2017; the next regularly scheduled redetermination is expected to be completed in October of this year. As of August 4, 2017, the Partnership had $381.0 million outstanding under the credit facility and $10.6 million in cash, providing approximately $180 million in available liquidity. Black Stone Minerals is in compliance with all financial covenants associated with its credit facility.

Acquisitions

Black Stone's acquisition activity in the second quarter of 2017 was focused on the Haynesville/Bossier play in East Texas and consisted primarily of the previously announced transactions to acquire mineral and royalty interests throughout Angelina and surrounding counties in East Texas, including the acquisition of the Angelina County Lumber Company assets. In total, the Partnership invested $18.1 million in cash and $45.7 million in equity for acquired assets during the quarter.

For the six months ended June 30, 2017, the Partnership had invested $66.5 million in cash and $57.9 million in common units for assets in East Texas and the Delaware Basin.

Subsequent to quarter end, Black Stone continued to build upon its Haynesville/Bossier position in East Texas. It has closed on approximately $11 million in acquisitions located in the Shelby Trough of East Texas. Additionally, the Partnership has entered into an agreement for approximately $4.6 million in cash and 590 thousand common units to acquire additional interests in the Shelby Trough. This acquisition is subject to customary closing conditions.

Working Interest Participation

In 2017, the Partnership incurred $10.4 million in the second quarter and $30.8 million in the first half participating as a non-operating working interest owner on its own minerals. Black Stone currently expects that it will invest between $40 and $50 million in 2017 in its working interest participation program, the majority of which will be deployed in the Haynesville Shale in the Shelby Trough area of East Texas. This estimate has been revised down from the previously provided guidance of $50 to $60 million. The decrease in expected capital expenditures relates to the deferral of completions of several high working interest wells in the XTO-operated program in the Shelby Trough, which will now be completed in early 2018.

Distributions

The Board of Directors of the general partner (the "Board") has approved cash distributions attributable to the second quarter of 2017 of $0.3125 per common unit and $0.20875 per subordinated unit. These distributions represent increases of $0.025 per unit ($0.10 per unit annualized) for both the common and subordinated units from the preceding quarter. Distributions will be payable on August 24, 2017 to unitholders of record on August 17, 2017.

In determining the amount of distributions to common and subordinated unitholders, the Board takes into account numerous factors, including the level of distribution coverage. In addition to the industry-accepted method of calculating distribution coverage, the Partnership also evaluates distribution coverage after deducting net working interest capital expenditures with a goal over the long-term of funding working interest capital expenditures with retained cash flow. The quarterly distribution coverage attributable to the second quarter of 2017 for all units was approximately 1.3x before net working interest capital expenditures and approximately 1.0x after net working interest capital expenditures.

Revised 2017 Guidance

The following table provides the assumptions for Black Stone's original and current 2017 guidance:

Production

Production guidance for the full year of 2017 is being increased by approximately 4% at the midpoint of provided guidance ranges, and reflects the strong performance from the first half of the year combined with expected moderate quarterly production increases for the remainder of 2017. The increase comes despite the deferral in completions of several high interest Haynesville Shale wells into 2018.

Lease Bonus

The guidance range of lease bonus and other income for 2017 is being increased by $5 million, driven by robust leasing across a broad portion of the portfolio throughout the first half of the year. The increase in guidance is tempered by a cautious outlook for the remainder of the year given uncertainty around commodity prices.

Information for Non-U.S. Investors

This press release is intended to be a qualified notice under Treasury Regulation Section 1.1446-4(b). Although a portion of Black Stone Minerals’ income may not be effectively connected income and may be subject to alternative withholding procedures, brokers and nominees should treat 100% of Black Stone Minerals’ distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business.

Non-GAAP Financial Measures

Adjusted EBITDA, distributable cash flow, and distributable cash flow after net working interest capital expenditures are supplemental non-GAAP financial measures used by our management and external users of our financial statements such as investors, research analysts, and others, to assess the financial performance of our assets and our ability to sustain distributions over the long term without regard to financing methods, capital structure, or historical cost basis.

We define 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, and non-cash equity-based compensation. We define distributable cash flow as Adjusted EBITDA plus or minus amounts for certain non-cash operating activities, estimated replacement capital expenditures, cash interest expense, and distributions to noncontrolling interests and preferred unitholders. We define distributable cash flow after net working interest capital expenditures as distributable cash flow less net working interest capital expenditures. Net working interest capital expenditures consists of all capital expenditures related to working interest wells less the recoupment of working interest expenditures under our farmout agreement.

Adjusted EBITDA, distributable cash flow, and distributable cash flow after net working interest capital expenditures 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 our financial performance.

Adjusted EBITDA, distributable cash flow, and distributable cash flow after net working interest capital expenditures have important limitations as analytical tools because they exclude some but not all items that affect net income (loss), the most directly comparable GAAP financial measure. Our computation of Adjusted EBITDA, distributable cash flow, and distributable cash flow after net working interest capital expenditures may differ from computations of similarly titled measures of other companies.
