Energy security is once again a headline issue as markets react to risks around the Strait of Hormuz and the potential impact on fuel costs. That keeps attention on nuclear energy stocks, which sit at the intersection of power reliability and inflation sensitive energy pricing. This article looks at three stocks from the Nuclear Energy Stocks screener that offer different ways to get exposure to this theme.

The three nuclear energy stocks covered below are just a sample from a wider set, and the full screen surfaced 19 more companies with equally compelling narratives that are not covered in this article. To go straight to the full Nuclear Energy Stocks results, use the Nuclear Energy Stocks screener to analyze, compare, and identify the ideas that best fit your own view of the sector.

Kirloskar Oil Engines (NSEI:KIRLOSENG)

Kirloskar Oil Engines is a Pune based industrial company that supplies diesel engines, gensets, pumps and power solutions to sectors such as infrastructure, data centers, agriculture and defense in India and overseas. It generates most of its revenue from its Business to Business segment at about ₹56.9b, with smaller but meaningful contributions from Business to Customer at about ₹11.4b and Financial Services at about ₹8.8b. The stock has a market cap of roughly ₹314.3b, which puts it firmly in the large cap bracket for Indian industrials.

Investors watching the Nuclear Energy Stocks theme may find Kirloskar Oil Engines interesting because it sits at the heart of backup power for data centers and critical infrastructure, highlighted by its recent 192 MW HyperNext order, while also serving more traditional industrial and agricultural demand. Forecasts point to strong earnings growth and high future return on equity, yet the company still faces real questions around heavy reliance on diesel engines, margin pressure in the B2C segment and capital tied up in underperforming financial services. The mix of a growing high horsepower and service business, an upcoming dividend decision this AGM season, and analyst debate about valuation makes this a stock where a bit of extra homework could be time well spent.

Kirloskar Oil Engines operates at the intersection of data center power needs and traditional diesel-reliant demand, yet the real story is in the numbers. Review the 2 key rewards and 3 important warning signs (1 is major!)

Larsen & Toubro (BSE:500510)

Larsen & Toubro is a large Mumbai based engineering and construction group that delivers big ticket infrastructure, energy and hi tech manufacturing projects in India and overseas. Most revenue comes from Infrastructure & Utilities at about ₹1.35t, with Energy Conventional at roughly ₹566.8b and Technology, Platforms & Services at about ₹565.6b, while Financial Services adds close to ₹189.2b. The company is a heavyweight in the Indian market with a market cap of roughly ₹5.56t.

Investors watching nuclear and wider energy infrastructure may find Larsen & Toubro hard to ignore. The company sits on a record order book and keeps adding large EPC wins across Middle East oil projects, offshore wind and power transmission, while also building exposure to data centers, green hydrogen and defense electronics. Earnings growth has been solid, margins are edging higher and capital efficiency is improving, yet a rich valuation and heavy dependence on government and Middle East contracts mean execution and geopolitical risk remain front of mind. The key consideration is whether the quality of the order pipeline and the shift toward higher margin tech and services can justify that risk profile over the coming years.

For Larsen & Toubro, an accelerating order book and rising margins set up a powerful story that many investors only partly see. Read the 2 key rewards and 1 important warning sign

Bharat Heavy Electricals (BSE:500103)

Bharat Heavy Electricals is a New Delhi based engineering group that builds and services power plants and heavy equipment for sectors such as coal, gas, hydro and nuclear power, rail, defence and industrial projects in India and overseas. Most revenue currently comes from the Power segment at about ₹274.3b, with the Industry segment adding roughly ₹85.7b, which shows how closely the business is tied to large power projects. The stock has a market cap of around ₹1.42t, placing it among the larger industrial companies in India.

Bharat Heavy Electricals has turned a prior loss into a quarterly profit and is now tied into themes that matter to energy focused investors, from large supercritical thermal projects to green hydrogen electrolyzers through its work with thyssenkrupp nucera. Historically, earnings growth has been strong, and analysts currently forecast that it will stay ahead of the wider Indian market, while revenue growth is expected by analysts to run in the mid teens. At the same time, a high P/E multiple, reliance on external borrowings and concerns around board independence mean expectations are already high and governance questions are still on the table. The tension between those growth projects, the current valuation and how management handles capital and oversight is where the real investment debate lies.

Momentum around Bharat Heavy Electricals is starting to catch up with its power and hydrogen projects, yet the real story could be what analysts expect next for earnings and revenue. Review the analyst forecasts for Bharat Heavy Electricals
