Business Overview: Black Stone Minerals, L.P. (NYSE: BSM)

---

Executive Summary

Black Stone Minerals, L.P. is one of the largest owners and managers of oil and natural gas mineral interests in the United States. Rather than drilling and operating wells itself, BSM leases its mineral acreage to third-party exploration and production operators and collects royalty and lease-bonus income — a non-cost-bearing, capital-light business model that generates substantial free cash flow available for distribution to unitholders. As of December 31, 2025, the partnership controlled roughly 16.9 million gross mineral acres (43.4% average net ownership), plus additional nonparticipating royalty interests (1.8 million gross acres) and overriding royalty interests (1.6 million gross acres), spanning approximately 71,000 producing wells across 41 states.

Core Business Model

BSM's model is structurally different from an exploration and production (E&P) company: it owns the mineral rights beneath the land rather than the wells or equipment, and earns royalty income (a percentage of production revenue) whenever an operator drills and produces oil or gas on its acreage, without bearing drilling, completion, or lease-operating costs itself. This makes BSM's cash flow highly leveraged to commodity prices and third-party operators' drilling decisions and capital allocation, while insulating it from the cost overruns and operational risk that E&P companies bear directly. The partnership supplements organic royalty income with strategic joint exploration and development agreements (for example with Aethon, Revenant, and Caturus in the Shelby Trough region) that commit operators to multi-year drilling programs on BSM's acreage while limiting BSM's own capital exposure through non-operated, farmout-style structures.

Business Segments

BSM does not report discrete operating segments in the traditional sense; its business is organized around geographic regions in which it holds mineral and royalty interests:

• Gulf Coast — the largest contributor to production (~20,870 Boe/d).
• Southwestern U.S. — Permian Basin-focused acreage (~5,716 Boe/d).
• Rocky Mountains — Bakken/Williston Basin exposure (~4,634 Boe/d).
• Mid-Continent, Eastern U.S., and Western U.S. — combined smaller contributors (~2,036 Boe/d).

Product Portfolio

As a mineral and royalty owner, BSM does not sell a product in the conventional sense; its "product" is its portfolio of mineral, royalty, and overriding-royalty interests, monetized through:

• Lease bonus income — upfront payments from operators for the right to drill on BSM's acreage.
• Royalty income — an ongoing percentage share of oil and gas production revenue.
• Overriding royalty interests (ORRIs) and nonparticipating royalty interests (NPRIs) — additional royalty-type income streams layered on specific acreage positions.

---

Competitive Landscape

BSM competes with other publicly traded mineral and royalty companies (such as Viper Energy, Sitio Royalties, and Kimbell Royalty Partners) for acquisitions of additional mineral acreage, as well as indirectly with private mineral owners and family offices that hold similar assets. Because BSM does not compete for drilling rigs, oilfield services, or E&P talent the way operators do, its competitive positioning is primarily about the scale, quality, and diversification of its existing acreage position and its ability to source accretive new mineral and royalty acquisitions.

Strategic Strengths & Risks

Strengths

• Massive, diversified acreage base (16.9 million gross mineral acres across 41 states) provides broad exposure to multiple basins and reduces single-asset or single-operator risk.
• Capital-light, non-cost-bearing model: BSM does not fund drilling or completion costs, generating high free-cash-flow conversion relative to E&P peers.
• Strategic development agreements (Shelby Trough joint exploration deals) commit operators to multi-year drilling programs, providing some visibility into future production growth without BSM capital outlay.
• Reserve base: 54,845 MBoe of total proved reserves, with the large majority (87.8%) already proved developed.

Risks

• Direct commodity price exposure: royalty income moves directly with realized oil and gas prices ($64.24/bbl oil and $3.41/Mcf gas in 2025), and BSM has no operational levers to offset price declines the way an E&P company might through cost-cutting.
• Dependence on third-party operator decisions: BSM cannot control the pace or scale of drilling on its acreage; operators' capital-allocation decisions directly determine BSM's production and revenue growth.
• Natural decline curves: like all oil and gas production, existing wells decline over time, requiring continued new drilling by operators (which BSM does not control) to sustain production levels.
• Regulatory and climate-policy risk: increasing regulatory and climate-related pressure on fossil fuel development could reduce future drilling activity on BSM's acreage over the long term.

Summary Conclusion

Black Stone Minerals occupies a structurally advantaged niche within the oil and gas value chain: as one of the largest mineral and royalty owners in the country, it captures the economic upside of drilling activity across a vast, diversified acreage base without bearing the capital or operational risk of drilling itself. This capital-light model produces strong free cash flow and distribution capacity, but it remains fundamentally a call option on operators' drilling decisions and commodity prices rather than a business BSM can drive through its own operational execution. Its moat rests on the scale and diversification of an acreage position that would be extremely difficult and expensive for a new entrant to replicate, tempered by its complete lack of control over the pace of development on that acreage.
