Business Overview: NOV Inc. (NYSE: NOV)

---

Executive Summary

NOV Inc. is a Houston, Texas-based designer, manufacturer, and supplier of equipment and technology to the global energy industry. NOV and its predecessor companies — most notably National Oilwell and Varco International, which merged in 2005 to form National Oilwell Varco before the company rebranded as NOV Inc. — have operated for more than 160 years, giving it one of the deepest installed bases and longest engineering track records in the oilfield equipment industry. The company now serves customers in 57 countries with roughly 31,600 employees.

NOV designs, builds, and services the capital equipment that drills, completes, and produces oil and gas wells — everything from land rigs and offshore drilling packages to drill bits, downhole tools, artificial lift systems, and subsea production equipment — and increasingly applies that same engineering base to adjacent energy markets such as offshore wind, geothermal, carbon capture, and advanced nuclear supply chains.

Why it matters: NOV is one of a small handful of global, full-line oilfield equipment manufacturers with the engineering depth, manufacturing scale, and decades-deep installed base to be the default supplier when operators and drilling contractors need mission-critical drilling and production equipment, giving it durable aftermarket and backlog-driven revenue even through industry downturns.

1. Core Business Model & How They Work

NOV earns revenue in two distinct ways that reflect its two reporting segments: shorter-cycle, transactional sales of tools, consumables, and services (parts, bits, downhole tools, inspection, digital solutions), and longer-cycle sales of large capital equipment and integrated systems (rigs, top drives, cranes, process systems) that are tracked through a multi-year order backlog. Both streams are reinforced by an aftermarket services and parts business tied to NOV's enormous historical installed base of equipment in the field.

The Max™ digital platform layers across both segments, collecting equipment and process data (with AI/machine learning analytics) to sell "equipment-as-a-service"-style offerings and strengthen the stickiness of the installed base, while NOV's closed-loop drilling technology and proprietary wired drill pipe (Downhole Broadband Solutions) are jointly developed and cross-sold across segments.

|     control, digital solutions, drill pipe & connections
|     FY2025 operating margin: 7.0% | Adj. EBITDA margin: 14.2%
|
|-- Energy Equipment -- $4,934M (56% of revenue; +1% YoY)

|
|-- Eliminations -- $(167)M

Energy Products and Services is NOV's transactional, higher-turnover segment — its drill bits, downhole tools, completion consumables, artificial lift, and digital offerings are sold or rented repeatedly over a well's life, giving this segment closer-to-real-time exposure to drilling and completion activity levels.

Energy Equipment is NOV's capital-goods segment, selling large, long-lead-time systems such as drilling rigs, top drives, cranes, and subsea and process equipment; because orders are booked well ahead of delivery, this segment carries a multi-year $4.34 billion backlog that smooths revenue versus near-term activity swings and increasingly includes equipment for energy-transition end markets (offshore wind installation vessels, geothermal, carbon capture, advanced nuclear).

4. Competitive Landscape

NOV's FY2025 10-K states that competition comes "primarily from publicly traded oilfield service and equipment companies and smaller independent equipment manufacturers," without naming specific competitors, and notes that some government-owned national oil companies favor local suppliers. Based on well-known industry structure, NOV's practical competitive set includes:

• Integrated oilfield service majors — SLB (Schlumberger), Halliburton, and Baker Hughes: These compete with NOV in overlapping categories such as drill bits, downhole tools, artificial lift, and digital/drilling-technology offerings, generally as part of broader integrated service packages rather than standalone equipment sales.
• Equipment-focused peers — Weatherford International, Forum Energy Technologies, and Dril-Quip: More direct equipment-manufacturing competitors, typically smaller and narrower in product-line breadth than NOV's full-line Energy Equipment and Energy Products and Services portfolio.
• Regional/national equipment manufacturers: In markets where governments favor local-content suppliers, smaller national manufacturers can win share NOV would otherwise capture, particularly in rig and land-equipment categories.

                              |
                       Narrow Product Line

NOV's positioning is as the broadest-line, most vertically capable pure equipment and technology manufacturer, versus integrated service majors that bundle equipment within personnel-heavy service contracts, and versus narrower equipment specialists that lack NOV's combined Energy Products and Services plus Energy Equipment breadth.

5. Strategic Strengths & Risks

Strengths (moat sources):

• 160-year installed base and switching costs: Decades of rigs, top drives, and downhole equipment already in the field create durable aftermarket parts, service, and upgrade revenue, because operators and drilling contractors face real cost, safety, and compatibility friction switching away from an incumbent equipment provider mid-fleet.
• Proprietary technology and brand: Patented systems like Downhole Broadband Solutions (wired drill pipe) and the Max™ digital platform differentiate NOV from lower-cost equipment manufacturers and support premium positioning in technically demanding segments (deepwater, automation).
• Global manufacturing and service scale: Operating in 57 countries with a full-line portfolio across both short-cycle tools and long-cycle capital equipment gives NOV diversification and scale that narrower equipment-only competitors (e.g., Dril-Quip) cannot match.
• Backlog visibility: The $4.34 billion Energy Equipment backlog provides multi-year revenue visibility that partially insulates the company from near-term activity swings.

Risks:

• Industry cyclicality: FY2025 revenue was roughly flat ($8,744 million vs. $8,870 million in 2024) while operating margin compressed meaningfully (5.6% vs. 9.9%), illustrating how sensitive NOV's profitability is to upstream capital spending cycles.
• Customer concentration and bargaining power: A relatively small number of large E&Ps, drilling contractors, and national oil companies drive capital equipment demand, and some NOCs explicitly favor local suppliers over NOV.
• Energy transition exposure on both sides: While NOV is diversifying into offshore wind, geothermal, carbon capture, and nuclear supply chains, its core revenue still depends heavily on oil and gas drilling and production activity, exposing it to long-term demand-transition risk if that diversification does not scale fast enough.
• Capital-intensive, lower-margin segment mix: Energy Equipment, while backlog-visible, carries long lead times and project-execution risk (cost overruns, delivery delays) typical of capital-goods manufacturing.

7. Summary Conclusion

NOV's moat rests on a combination most equipment competitors cannot fully replicate: a 160-year installed base that generates recurring aftermarket demand, proprietary drilling and digital technologies (wired drill pipe, Max™) that differentiate it from commodity equipment suppliers, and the global manufacturing scale to serve both short-cycle consumable and long-cycle capital equipment needs across 57 countries. The Energy Equipment backlog of $4.34 billion further cushions the business against near-term activity swings.

The company's biggest forward risk is the oilfield capital-spending cycle itself — FY2025's flat revenue but sharply lower operating margin shows how quickly profitability can compress even when top-line holds up, and NOV's longer-term success will depend on how effectively it can grow adjacent energy-transition equipment markets (offshore wind, geothermal, carbon capture, nuclear supply chain) to offset the structural risk that oil and gas drilling activity — its core demand driver for over a century — eventually declines.
