NOV Inc. (NOV)

NOV Inc. (New Offshore Ventures, now simply NOV) supplies the equipment, components, and digital systems that allow energy companies to drill, complete, and produce oil and natural gas wells. It is the world’s largest equipment provider to the oil and gas industry, serving customers across onshore and offshore operations in roughly 150 countries. The company’s fortunes move in tight correlation with energy prices and capital spending by the major oil and gas producers, making it a cyclical play on both upstream energy economics and the health of global demand for crude and liquefied natural gas.

The machinery that goes underground

NOV’s core business is manufacturing and servicing the specialised equipment that upstream energy companies rely on. The company did not invent this category; it inherited much of its position through acquisition and consolidation across a fragmented industry over decades. Unlike producers like ExxonMobil or ConocoPhillips, NOV does not pump oil or own reserves. Instead, it sells the rigs, pumps, blowout preventers, wellheads, pipe connections, and software that customer companies own and operate. Some of this equipment is sold outright; some is rented on a contract basis. All of it requires ongoing maintenance, spare parts, and technical support — a high-margin aftermarket business that NOV guards carefully.

The company’s position depends entirely on upstream capital spending. When oil prices are high and energy companies are confident about future demand, they invest in new wells, new rigs, and new completion systems. When prices collapse, all that spending stops almost overnight, inventories pile up at customer sites, and NOV’s own backlog of orders shrinks. The company has lived through multiple such cycles — booms in 2010–2014, the collapse of 2015–2016 when crude fell below $30 a barrel, a recovery in 2017–2018, and the shock of the pandemic in 2020. Each downturn forces restructuring and layoffs; each recovery allows the company to rebuild. That pattern is so central to NOV’s history that understanding it is half of understanding the investment.

Three operational divisions

NOV organises its business into three divisions, each serving a different phase of the well lifecycle and each exposed to different competitive and operational pressures.

Wellbore Technologies designs and manufactures equipment for drilling. This includes drill pipe (the spinning hollow steel that connects the surface to the drill bit), drillbit cones and components, borehole and drilling fluids, bottomhole assemblies, and the enormous blowout preventers that sit atop every well to contain pressure if something goes wrong. These are mission-critical — a failure can kill people and shut down a field — so customers care deeply about reliability and engineering integrity. Competition is global and divided among a few large rivals and many smaller specialists. The division’s revenue is partially recurring because drillpipe wears out and is consumed in use; much is also lumpy, because a customer might order a complete rig’s worth of tooling at once.

Completion & Production Solutions makes equipment and systems for the second and third phases of a well’s life. Once a well is drilled, it must be completed with tubing, packers, safety valves, and other gear that isolates different rock layers and allows the company to produce from multiple zones within the same hole. After completion comes production — managing the flow of oil and gas out of the ground. This segment supplies the manifolds, connectors, valves, and control systems that customers use for years afterward. It also includes software and digital monitoring tools that help operators optimise production and reduce downtime. Because production equipment stays in the ground for the life of the well, this segment has a large installed base and a steady aftermarket stream of upgrades, repairs, and replacements.

Rig Technologies builds jackup drilling rigs, tender-assist rigs, and other floating structures for deepwater drilling. Rig building is a capital-intensive, low-margin business with long lead times and razor-thin competitive spreads. Customers order rigs years in advance; if a project is cancelled or delayed, the rig half-built sits idle. Rig prices are volatile and depend on scrap-steel costs and global supply-demand for rigs at any given moment. This segment is the most cyclical of the three and the one where NOV is most exposed to customer credit risk — if an oil company backing a rig order goes bankrupt, NOV may lose both the contract and the invested capital.

How revenue flows

The mix of cash inflow across these three divisions shifts with the energy cycle. When oil prices are high and upstream companies are investing, Rig Technologies books large orders and works through a multi-year backlog. During downturns, rig orders dry up; the division shifts into service mode on existing rigs in the field. Wellbore Technologies is steadier but still cyclical — drilling activity falls during down years but does not stop entirely. Completion & Production Solutions is the most resilient, because upgrades and support work on existing equipment continues even when new capital projects are frozen.

The vast installed base of NOV equipment in the field — millions of pieces of gear sitting on thousands of rigs and wells worldwide — means that aftermarket revenue (spare parts, repairs, upgrades, rental fees) never goes to zero. But aftermarket business is lower-margin than new sales, and it cannot fully offset the loss of gross margin when the company is forced to cut prices to keep the lines running during a downturn.

Competitive pressures and long-term questions

NOV competes against large integrated oilfield-services firms like Schlumberger and Baker Hughes, as well as specialised equipment makers in each niche. The competitive advantages are engineering depth, global distribution and service capability, and the installed base of customers who already use NOV systems and parts. The risks are technological and market-structural. As energy companies experiment with smaller, cheaper wells in unconventional plays, they sometimes standardise on lower-cost equipment suppliers. As deepwater exploration slows due to geopolitical pressure and the energy transition, deepwater rig demand may not recover to pre-2015 levels. And as customers digitise their operations, software-driven optimisation can reduce the number of physical assets in the field — fewer wells, more output per well.

Overshadowing everything is the long-term energy transition. NOV’s entire customer base is the upstream oil and gas industry. If global energy spending shifts durably away from fossil fuels, or if stricter environmental regulations reduce profitable drilling frontiers, NOV will face a shrinking addressable market. The company is investing in adjacent areas — geothermal drilling, carbon-capture equipment — but these are sidelines, not the core business yet.

How to research NOV

Start with the company’s annual 10-K filing (SEC CIK 0001021860), which breaks down revenue and backlog by segment and by geography, and details the key risks management sees. Pay close attention to the backlog — it is reported quarterly and gives a forward-looking signal of sales momentum that is not as cloudy as current-year earnings. Watch the gross-margin trend: during booms, margins compress as customers shop for price, and during downturns the company fights harder to retain share. Follow upstream capital spending projections from industry analysts and the majors’ earnings calls; when those forecasts rise, NOV’s order book typically follows with a lag.

The stock is best understood as a leveraged bet on both oil prices and upstream capex. It is cheaper than the integrated oil companies at market troughs and more volatile. For investors, that cyclicality is the defining feature — not the engineering or the market position, but the amplitude and timing of the business cycle.
