NOV Inc., the Houston-based oilfield equipment and services manufacturer, has cut its earnings guidance, pointing to higher costs and delivery disruptions tied to the war involving Iran.

The company, which supplies drilling equipment, pressure pumps, and tubular handling systems to rig contractors and drillers across North American shale and international basins, said the conflict has pushed up input costs and slowed shipments of its products to customers.

NOV had previously guided for improved margins through 2025 as drilling and completion activity recovered in US land basins including the Permian and international markets in the Middle East. The revised guidance walks back that outlook, with the Iran conflict driving freight complications and material cost increases that the company now expects to weigh on near-term earnings.

For service companies and equipment suppliers with exposure to Middle East logistics routes, the conflict has created two distinct pressures. First, escalating insurance and shipping costs on routes near the Strait of Hormuz have lengthened delivery timelines for heavy equipment moving between manufacturing hubs and regional customers. Second, price volatility in steel and other input commodities has squeezed margins on fixed-price contracts signed before hostilities began.

NOV's guidance cut stands out because the company had positioned itself as a beneficiary of the drilling upcycle, with its Rig Technologies, Wellbore Technologies, and Completion and Production Solutions segments all reporting improving bookings in recent quarters. Demand for its automated drilling controls and pressure pumping equipment has tracked the rig count recovery in US basins and the expansion of offshore work in Brazil, Guyana, and the Middle East.

The revised outlook signals that even suppliers insulated from direct combat-zone exposure face second-order effects from the conflict. Equipment makers rely on global supply chains for components ranging from forged steel to electronics, and any disruption in Gulf shipping lanes or air freight corridors feeds directly into cost structures and delivery schedules.

Investors and analysts will watch NOV's next earnings call for quantification of the guidance reduction, the specific cost lines affected, and management's view on whether delivery delays will push revenue into later quarters or erase it entirely. Competitors including SLB, Baker Hughes, and Halliburton, all of which maintain significant Middle East footprints, may face comparable pressures on their own logistics and cost structures.

The watch items now are the duration of hostilities, the status of shipping through the Strait of Hormuz — through which roughly a fifth of global oil supply transits — and whether NOV's customers in Saudi Arabia, the UAE, and Qatar begin to defer or slow equipment deliveries. Any sustained closure or disruption of Gulf shipping lanes would compound cost pressures across the oilfield services sector and could trigger a broader wave of guidance revisions among peers.
