What happened?

A number of energy stocks jumped in the afternoon session after shipping attacks in the Persian Gulf sparked renewed supply concerns, driving crude oil prices sharply higher. The Wall Street Journal reported that front-month Brent crude rose 1.2% to $92.55 a barrel, recovering from a sharp selloff. West Texas Intermediate futures rose 0.7% to $86.67.

The Journal said the strikes tempered expectations of a diplomatic resolution to the U.S.-Iran conflict, and that supply risks in the region persist. A bottleneck in that shipping lane can tighten the crude available to buyers and add a geopolitical premium to the price. Higher oil prices can support revenue and cash flow for producers.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming in on NESR

NESR’s shares are extremely volatile and have had 31 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The biggest move we wrote about over the last year was 3 months ago when the stock gained 17.6% on the news that Brent crude failed to break below $80 and rebounded to the mid-$80s, as traders kept a geopolitical risk premium priced into oil despite ongoing Strait of Hormuz negotiations. Over the previous 24 hours, the UAE-vessel incident reversed the earlier price drop that had assumed a path to de-escalation. At the same time, Kpler data from the previous two days showed shipping traffic through the Strait of Hormuz plummeted about 33%, with only a handful of vessels crossing daily. Concurrently, Iran’s Parliament reviewed a bill that would permanently ban U.S., Israeli, and other “hostile” vessels from the waterway and impose heavy cargo fines — a legislative signal that the restriction could become more formal, not less. E&P equities are a leveraged claim on the price of oil. When traders mark crude higher because a major export corridor looks less secure, expected cash flows for producers with high operating leverage to WTI and Brent rise in the same step.

The mechanism is direct: a physical drop in Hormuz transit volumes and a fresh attack risk premium raise the probability of tighter near-term supply; higher spot crude then directly feeds revenue and free-cash-flow estimates for Devon, Diamondback, EOG, and peers. That is a re-pricing of supply-shock risk, not proof of a multi-year demand boom. The move still leaves open whether Hormuz flows stabilize, whether the Iranian bill advances, and whether diplomacy can reassert itself as the dominant narrative. The next confirmation or challenge will come from daily tanker-crossing data, any further incidents in or near the strait, and whether Brent holds above the levels set by this weekend’s risk spike.

NESR is up 39.1% since the beginning of the year, but at $21.97 per share, it is still trading 39.5% below its 52-week high of $36.31 from August 2026. Investors who bought $1,000 worth of NESR’s shares 5 years ago would now be looking at an investment worth $1,823.
