Business Overview: Oil States International, Inc. (NYSE: OIS)

---

Executive Summary

Oil States International, Inc. is a Houston, Texas-based manufacturer of highly engineered capital equipment and consumable products for the energy, military, and industrial sectors. Founded in 1942 and incorporated in Delaware, the company has evolved from a diversified oilfield services conglomerate into a more focused manufacturer of mission-critical offshore production and downhole completion equipment, having exited its drilling-rig business (final rigs sold in August 2024) and substantially restructured its onshore U.S. land operations through 2025.

Oil States matters to the offshore energy supply chain because its Offshore Manufactured Products segment makes the connectors, riser systems, mooring components, and subsea hardware that deepwater operators and shipyards cannot easily source elsewhere — equipment with multi-year qualification cycles and safety-critical specifications. With roughly $669 million in 2025 revenue and a 2,172-person global workforce, Oil States is a mid-cap, cyclical, but increasingly backlog-driven business whose fortunes now track offshore and subsea capital spending more than the volatile U.S. land rig count.

1. Core Business Model & How They Work

Oil States manufactures and sells capital equipment and consumable products, and separately provides well-site services, to oil and gas operators, drilling contractors, OEMs/shipyards, and — increasingly — military and non-energy customers such as offshore wind and subsea mineral-gathering projects.

[ Engineering & Qualification ] ➡️ [ Manufacturing (Houston & int'l facilities) ] ➡️ [ Direct Sale / Rental to Operators, Drillers, Shipyards ] ➡️ [ Field Service & Aftermarket Parts ] ➡️ [ Backlog Conversion on Multi-Year Offshore Projects ]

Key Operational Drivers

1. Engineered, Qualification-Heavy Products: Much of Oil States' equipment — subsea connectors, riser systems, mooring hardware — must pass lengthy qualification and certification processes before being approved for use on a specific offshore project, which slows new entrants and lengthens customer relationships.
2. Backlog-Driven Offshore Cycle: Offshore Manufactured Products sells into long-lead-time deepwater and FPSO (floating production storage and offloading) projects. Backlog reached $435 million at year-end 2025, up from $311 million a year earlier and the highest level since March 2015, with roughly half expected to convert to revenue in 2026.
3. Consumables & Aftermarket: Downhole Technologies and parts of Completion and Production Services generate recurring, higher-margin consumable revenue (perforating systems, frac plugs, toe valves) tied to well completion and intervention activity rather than long-cycle capex.
4. Portfolio Restructuring Toward Offshore/Military/Non-Energy: Management exited drilling rigs in 2024 and has been reducing exposure to the structurally oversupplied U.S. land completion market, while pursuing offshore wind, subsea minerals, and military end-markets as diversification.

1. Offshore Manufactured Products (~64% of 2025 Revenue)

Engineered systems for offshore and deepwater production: subsea and surface connectors, riser systems, valves, mooring systems, and cranes, sold to operators, drilling contractors, and shipyards. This segment also increasingly serves military customers and non-energy adjacencies such as offshore wind and subsea mineral gathering. It is the company's largest and most profitable segment and the main beneficiary of the current offshore/deepwater upcycle.

2. Completion and Production Services (~17% of 2025 Revenue)

Equipment and services supporting the completion and production phases of wells, in both onshore and offshore settings, including pressure control equipment and extended-reach downhole technology. The company sold its remaining drilling rigs in August 2024, completing its exit from contract land drilling and leaving this segment focused on well-site equipment and services.

3. Downhole Technologies (~18% of 2025 Revenue)

Perforating systems, frac plugs, toe valves, and other consumable tools used in well completion, intervention, and decommissioning. This is Oil States' most direct exposure to U.S. land well-completion activity, and it absorbed the bulk of the company's 2025 asset impairment charges as that market softened.

Offshore Manufactured Products

• Key Competitors: Baker Hughes, the Hutchinson Group (a Total S.A. subsidiary), NOV, OneSubsea, and TenarisHydril.
• Dynamics: Oil States competes against far larger, diversified oilfield service and subsea-equipment companies. It differentiates through deep, product-specific engineering (connectors, riser, mooring) rather than trying to match the breadth of a Baker Hughes or NOV, and benefits from long qualification cycles that make it costly for operators to re-qualify a new supplier mid-project.

Completion and Production Services / Downhole Technologies

• Key Competitors: A large number of smaller, often private, regional completion-equipment and consumables providers, alongside some of the largest oilfield service companies (e.g., Halliburton, Baker Hughes, NOV) that offer competing frac plugs, perforating systems, and pressure-control equipment.
• Dynamics: These segments are far more fragmented and commodity-like than Offshore Manufactured Products, with pricing pressure from numerous smaller competitors during U.S. land downturns — the dynamic that drove 2025's impairment charges in Downhole Technologies.

5. Strategic Strengths & Risks

Competitive Strengths (The Moat)

• Qualification Barriers in Offshore Equipment: Subsea connectors, riser, and mooring systems require lengthy, project-specific qualification before deployment, which protects incumbent suppliers like Oil States from easy displacement mid-project.
• Record Offshore Backlog: The $435 million Offshore Manufactured Products backlog (highest since March 2015) provides multi-quarter revenue visibility and reflects a renewed deepwater/floating-production investment cycle.
• Balance Sheet Repair: Total debt fell from $125.3 million to $55.0 million during 2025 (via repurchase of $70.4 million of its 4.75% convertible notes), and year-end cash of $69.9 million exceeded total debt — a meaningfully de-risked capital structure heading into 2026.
• New, More Flexible Credit Facility: In January 2026, Oil States replaced its asset-based revolver with a cash-flow-based facility (a $75.0 million revolver plus a $50.0 million multi-draw term loan, maturing January 2030), with $112.9 million available and no borrowings outstanding as of February 2026.

Strategic Risks & Vulnerabilities

1. U.S. Land Cyclicality in Downhole Technologies: The 2025 downturn in U.S. land completion activity drove $121.1 million in non-cash asset impairments, $91.9 million of which hit Downhole Technologies — underscoring this segment's exposure to commodity-price-driven drilling/completion swings.
2. GAAP Losses Despite Operational Improvement: Oil States posted a $(109.4) million net loss in 2025 (versus a $(11.3) million loss in 2024), driven almost entirely by non-cash impairments and roughly $124.9 million of fourth-quarter restructuring/impairment charges tied to the U.S. land exit — even as adjusted EBITDA and operating cash flow both improved year over year.
3. Customer Concentration in Large Offshore Projects: Revenue in the largest segment depends on a relatively small number of major offshore/deepwater project awards; the timing of FPSO and subsea development sanctioning can create lumpy quarterly results.
4. Competing Against Far Larger Diversified Players: Baker Hughes, NOV, and Total's Hutchinson Group all have substantially greater scale, R&D budgets, and balance sheets than Oil States in the offshore equipment space.

7. Summary Conclusion

Oil States International has repositioned itself from a diversified, drilling-rig-exposed oilfield services conglomerate into a more focused offshore equipment manufacturer, exiting rigs in 2024 and absorbing a painful but largely non-cash restructuring of its U.S. land completion business through 2025. The headline $(109.4) million GAAP net loss obscures a business whose underlying cash generation, backlog, and balance sheet actually strengthened over the year: adjusted EBITDA rose, operating cash flow more than doubled, debt was cut by over half, and the company ended the year in a net-cash position with a freshly negotiated, more flexible credit facility.

The forward story now hinges on the Offshore Manufactured Products segment's record $435 million backlog converting into revenue and margin as the offshore/deepwater capex cycle continues, while Downhole Technologies stabilizes alongside (or despite) a still-soft U.S. land market. Oil States' moat is narrower than a diversified major's — it wins on deep, qualification-protected engineering in specific offshore product niches rather than broad scale — but 2025's balance-sheet repair gives it more room to execute on that offshore recovery than it has had in nearly a decade.
