Rising tension in the Red Sea and Bab el Mandeb Strait has pushed shipping risks and oil supply worries back into focus, just as flows pick up again after the partial reopening of the Strait of Hormuz. For investors, this kind of supply chain stress can quickly reshape which oil and gas producers look more resilient or more exposed to disruption, insurance costs and pricing swings. This article walks through 3 stocks from the Energy Sector, Oil & Gas Producers screener that appear positively exposed to the latest Red Sea shock and may warrant a closer look in a diversified portfolio.

Tamarack Valley Energy (TSX:TVE)

Overview: Tamarack Valley Energy is a Calgary based producer that explores for, develops, and sells oil, natural gas, and natural gas liquids in Alberta, with its core operations centered on the Clearwater heavy oil play. The company focuses on drilling and production in the Western Canadian sedimentary basin, turning subsurface resources into saleable energy products.

Operations: Tamarack Valley Energy generates all of its CA$1.36b in revenue from oil and gas exploration and production activities in Canada.

Market Cap: CA$6.14b

For investors watching Red Sea supply risks and potential support for global oil prices, Tamarack Valley Energy offers direct exposure through a pure play Clearwater production base, now sharpened by the C$804.0 million sale of its Charlie Lake assets and updated guidance of 61,500 to 63,000 boe/d for 2026. The company has moved from carrying material net debt to highlighting debt elimination and undrawn credit capacity above C$525 million, while also lifting its quarterly dividend to C$0.05 per share and signaling room for buybacks. The trade off is clear: investors are getting a business still working through a recent unprofitable stretch and funding risk from external borrowing, but with rising cash returns, improving capital efficiency, and significant exposure to periods of firm oil prices.

Tamarack Valley Energy’s shift from net debt pressure to balance sheet flexibility is the real story here, and the full picture only comes into focus when you weigh that against its recent unprofitable stretch in the Tamarack Valley Energy financial health report

Harbour Energy (LSE:HBR)

Overview: Harbour Energy is an independent oil and gas company headquartered in London that acquires, explores, develops, and produces crude oil, natural gas, and condensate across the UK, Norway, Germany, Mexico, Argentina, North Africa, and Southeast Asia, while also building a business in carbon capture and storage and related services.

Operations: Harbour Energy generates most of its revenue from Norway at about $4.33b and the UK at about $3.87b, with additional contributions from Germany ($680m), Argentina ($574m), Mexico ($158m), North Africa ($315m), and Southeast Asia ($146m), partly offset by corporate items and eliminations.

Market Cap: £3.90b

Red Sea tensions put Harbour Energy on the radar for investors looking at how upstream producers respond when shipping routes and oil supply look fragile. Harbour combines sizable existing production, including exposure to Brent crude and European gas, with an expanded international asset base that reduces reliance on the mature UK North Sea. The stock trades well below some fair value estimates and carries a high dividend yield that is not fully covered by earnings, alongside funding and policy risks. For anyone tracking oil price swings, carbon capture projects, and the integration of large acquired assets, Harbour Energy’s mix of potential upside and clear pressure points may warrant closer attention.

Harbour Energy’s mix of broad production, high yield and policy risk raises a key question: is the current share price masking something in the analysis report for Harbour Energy

Cheniere Energy (LNG)

Overview: Cheniere Energy is a US based LNG infrastructure company that chills natural gas into liquid form at its Sabine Pass and Corpus Christi terminals, then loads it onto tankers for export to customers around the world under long term contracts. It effectively runs large scale energy “toll roads,” charging fees for processing and loading LNG while also marketing some LNG and natural gas directly.

Operations: Cheniere Energy generates about US$20.8b in revenue from its Oil & Gas Integrated operations, primarily tied to LNG processing and related activities.

Market Cap: US$51.5b

Cheniere Energy sits at the center of global LNG trade just as supply security is back in the spotlight, with Red Sea and Strait of Hormuz disruptions pushing buyers to value reliable US export capacity even more. Around 95% of its portfolio is under long duration contracts, which can provide cash flow visibility. At the same time, the stock carries a high P/E multiple and a balance sheet built on significant debt, as well as recent margin pressure and a quarterly net loss in early 2026. Major banks have highlighted its long term contract base and expansion potential, while the market continues to debate valuation and leverage. Investors following LNG pricing and energy security themes may want to understand what the current volatility could mean for Cheniere’s next chapter.

Cheniere Energy’s rich P/E and long term contracts raise a sharp question: is current pricing overlooking key LNG demand and leverage trade offs hiding in the analysis report for Cheniere Energy
