Oil prices have recently slipped as talk of a possible Iran US thaw cools inflation worries and lifts risk appetite in equities. When inflation fears ease, investors often look harder at long term power sources that can run without constant fuel price swings. That puts nuclear energy stocks on many watchlists. This article highlights three nuclear focused stocks from our screener that stand out for further research.
The three nuclear energy stocks below are just a starting sample, and the full screen surfaced 20 more companies with equally compelling narratives that are not covered here. If you want to move faster, head straight to the Nuclear Energy Stocks screener to identify, compare, and analyze opportunities in this theme.
Kirloskar Oil Engines (NSEI:KIRLOSENG)
Overview: Kirloskar Oil Engines is a Pune based engineering company that makes diesel and gas engines, gensets, pumps and related power solutions used across infrastructure, data centers, construction, agriculture, defense and other industrial sectors in India and overseas. The company also sells spares, fluids, firefighting systems and offers financing and after sales services that keep its large installed base running.
Operations: Kirloskar Oil Engines generates most of its revenue from the B2B segment at about ₹56.9b, with smaller contributions from B2C at about ₹11.4b and financial services at about ₹8.8b, and the bulk of sales come from India at about ₹68.0b versus roughly ₹9.0b from exports.
Market Cap: ₹325.9b
Kirloskar Oil Engines sits at the heart of India’s push for resilient power, with engines and gensets that serve everything from construction sites to hyperscale data centers, as shown by its June 2026 order for 192 MW of backup capacity for digital infrastructure. Earnings growth has recently run ahead of the broader machinery sector. Analysts expect strong revenue and profit expansion. At the same time, the stock trades on a rich P/E and Simply Wall St’s cash flow model suggests the price already incorporates a lot of positive expectations. In addition, the company relies on diesel technology, faces pressure on margins and has concentrated funding from external borrowing. The upside story is attractive, but the risks deserve close attention.
Kirloskar Oil Engines has earnings momentum and a full order book; however, the rich P/E raises questions about what is already priced in. Get the 2 key rewards and 3 important warning signs (1 is major!)

Larsen & Toubro (BSE:500510)
Overview: Larsen & Toubro is a Mumbai based engineering company that delivers large scale infrastructure, energy, defence and technology projects, handling everything from metro lines and power grids to refineries, nuclear and green hydrogen equipment, defence platforms, aerospace systems and digital infrastructure across India and overseas.
Operations: Larsen & Toubro generates most of its revenue from Infrastructure & Utilities at about ₹1.35t, followed by Energy, both conventional and related activities, at about ₹567.0b, Technology, Platforms & Services at about ₹565.6b, Manufacturing & Products at about ₹148.6b, Financial Services at about ₹189.2b and Development Projects at about ₹49.7b, with inter segment and adjustment items netted at the group level.
Market Cap: ₹5,568.8b
Larsen & Toubro is positioned at the center of large infrastructure, energy transition and defence spending, backed by an order book of ₹6.13t and a pipeline in areas like hydrocarbon, offshore wind, data centers and green hydrogen. About half of its orders now come from outside India, especially the Middle East, which can reduce the impact of domestic policy swings but also exposes investors to regional and regulatory risk. Analyst expectations for earnings growth in the mid teens, rising margins, earnings quality and capital efficiency have drawn attention, yet the stock trades on a higher P/E than the broader Indian construction sector and relies significantly on external borrowing and a relatively new management team. The mix of multi year project visibility alongside execution and funding risks makes L&T a potential candidate for investors researching nuclear and energy infrastructure exposure.
Larsen & Toubro’s huge order book and global projects can look like the full story, yet the higher P/E and funding mix raise deeper questions. Review the 2 key rewards and 1 important warning sign for the twist most investors may be missing.
Bharat Heavy Electricals (BSE:500103)
Overview: Bharat Heavy Electricals is a New Delhi based engineering company that supplies equipment and turnkey solutions for coal, gas, hydro and nuclear power plants, as well as rail transportation, transmission, defence, aerospace, industrial systems, solar and battery storage, and e mobility projects in India and overseas.
Operations: Bharat Heavy Electricals generates most of its revenue from the Power segment at about ₹274.3b, with a smaller contribution from the Industry segment at about ₹85.7b.
Market Cap: ₹1,429.0b
Bharat Heavy Electricals catches the eye because it sits at the crossroads of conventional and nuclear power, grid equipment and green hydrogen. The company currently shows a mix of sharp earnings momentum and real risk. Earnings have moved from a loss to a profit, with net margins now 6.8%. At the same time, the stock trades on a rich P/E, relies entirely on external borrowing and has an unstable dividend record. Governance is another watchpoint, with no independent directors and many new board members. The green hydrogen alliance with Thyssenkrupp Nucera and recent mega project wins indicate a broader corporate story that the headline numbers do not fully explain.
Bharat Heavy Electricals is shifting from losses to profit with 6.8% margins, yet its rich P/E, external borrowing and governance questions leave a puzzle. Read the 2 key rewards and 1 important warning sign
