Peace signals between the U.S. and Iran, extra IAEA oversight, and a toll free reopening of the Strait of Hormuz have shifted attention back to how quickly risk premiums can change in global energy markets. For investors watching large, financially solid oil and gas stocks in the U.S., UK, Canada, and Australia, this mix of easing tensions and lingering uncertainty could reshape how certain companies are priced. This article looks at 3 stocks from the Global Energy Sector screener that appear closely tied to the news, helping you decide whether they deserve a closer look or a wider berth in your portfolio.

National Energy Services Reunited (NESR)

Overview: National Energy Services Reunited is a Houston based oilfield services company that supports drilling and production across the Middle East and North Africa, offering hydraulic fracturing, coiled tubing, cementing, artificial lift and safety systems, alongside drilling rigs, logging, fluids and thru tubing solutions.

Operations: NESR generates about US$869 million from Production Services and US$557 million from Drilling and Evaluation Services, with roughly US$1.4b of its revenue coming from the Middle East and North Africa and a small contribution from the rest of the world.

Market Cap: US$2.5b

National Energy Services Reunited sits at the heart of MENA oil activity, so a toll free reopening of the Strait of Hormuz and a formal easing in U.S. Iran tensions directly support its ability to keep rigs turning and wells serviced with fewer supply chain headaches. At the same time, the stock is described as heavily undervalued against some fair value estimates and carries strong earnings growth forecasts, yet trades on a rich P/E and relies on higher risk external borrowing, which raises questions about how much optimism is already priced in. Combined with long term national oil company contracts and growing sustainability projects, investors face a mix of resilience, concentration risk and a potentially underappreciated re rating narrative that still requires further assessment.

National Energy Services Reunited looks like an underappreciated Middle East workhorse, with earnings expectations and long term contracts that do not fully square with its rich P/E.

Gulf Marine Services (LSE:GMS)

Overview: Gulf Marine Services operates self propelled, self elevating support vessels that provide offshore construction, heavy lifting, accommodation, well intervention and manpower services to oil and gas and renewables clients across the Middle East and Europe.

Operations: Gulf Marine Services generates about $87.4m from E Class vessels, $54.7m from K Class vessels and $46.1m from S Class vessels, with revenue concentrated in Qatar, Saudi Arabia and the United Arab Emirates.

Market Cap: £211.8m

Gulf Marine Services is tightly linked to offshore activity in the Gulf, so a toll free reopening of the Strait of Hormuz and an interim peace deal that lowers regional risk premiums directly support demand for its vessels and services. Forecast earnings growth of around 35.5% a year and a share price that sits well below some fair value estimates have caught investors’ attention. However, margins have compressed, net profit fell after a one off $10.1m loss and all liabilities are funded through higher risk borrowing. When combined with a strong contract backlog, recent vessel deployments in new regions and an experienced, largely independent board, Gulf Marine Services becomes a stock where stabilizing geopolitics could matter a lot more than the recent share price suggests.

Gulf Marine Services’ compressed margins and higher risk borrowing could be masking a very different story as contracts stack up and regional risks ease. Get the full picture in the 2 key rewards and 2 important warning signs

Excelerate Energy (EE)

Overview: Excelerate Energy is a Texas based LNG specialist that owns and operates floating regasification terminals, providing the ships, crew and technical services that turn imported liquefied natural gas back into usable gas for power, industrial customers and utilities around the world.

Operations: Excelerate Energy generates about US$1.35b from gas utility activities, with revenue spread across North America, Latin America, the Middle East, Asia Pacific and Europe.

Market Cap: US$4.1b

Excelerate Energy gives you exposure to LNG infrastructure at the point where energy security and cleaner fuel switching intersect, backed by long term, take or pay style contracts and projects such as Iraq’s large scale floating regasification terminal. The company benefits when routes like the Strait of Hormuz stay open, reducing disruption risk to its supply chains and to customers in regions such as the Middle East, Asia and Latin America. It still carries thin margins, a premium P/E and questions about subscale operations and lower gross profitability versus peers. That mix of contracted growth, geopolitical sensitivity and structural profitability concerns means Excelerate Energy could look either underrated or overhyped depending on how you weigh LNG demand and execution risk.

Excelerate Energy’s contracted LNG projects and premium P/E suggest the market might be missing a key angle on its future earnings power. Walk through the analyst forecasts for Excelerate Energy and see what the market might be pricing in or ignoring.
