Euro area manufacturing is showing resilience and energy prices remain a key focus for policymakers, which keeps attention on how the world sources reliable power. That backdrop puts nuclear energy stocks on many radar screens as investors look for businesses tied to long term electricity demand rather than short term consumer swings. This article highlights three stocks from our Nuclear Energy Stocks screener that help bring this theme into sharper focus.

The stocks highlighted below are just a starting sample from this nuclear energy theme, and the full screen surfaced 19 more companies with equally compelling narratives that are not covered here. To identify and analyze your own highest conviction nuclear ideas straight from the screener, head into the Nuclear Energy Stocks screener.

Kirloskar Oil Engines (NSEI:KIRLOSENG)

Overview: Kirloskar Oil Engines is a Pune based power equipment company that builds diesel and gas generator sets, engines and related control systems used across industries, including backup and emergency power solutions for critical sites such as data centers and nuclear facilities. Alongside these theme linked products, it also serves wider markets like agriculture, construction, marine, defense and fluid handling, supported by aftermarket services and financial solutions.

Operations: Kirloskar Oil Engines generates most of its revenue from the B2B segment at about ₹58,979 million, with smaller contributions from B2C at about ₹11,478 million and Financial Services at about ₹8,932 million.

Market Cap: ₹305.4 billion

Investors looking at nuclear energy security may find Kirloskar Oil Engines interesting because its generator sets and electrical control systems are already used as high capacity standby power for critical infrastructure, including a recent 192 MW Hyperscale AI data center order, which hints at similar applications in nuclear facilities. The stock trades on a relatively high P/E and relies fully on external borrowing, which raises questions about how much optimism is already priced in. The mix of earnings quality, returns profile and meaningful debt and valuation risk may make Kirloskar Oil Engines a stock worth a closer look for this theme.

Larsen & Toubro (BSE:500510)

Overview: Larsen & Toubro is a Mumbai based engineering and construction group that delivers large infrastructure, energy and industrial projects across India and overseas. Its Hi Tech Manufacturing arm designs and refurbishes critical equipment and systems for nuclear reactors and other process plants. Alongside this nuclear linked work, the company is active in transport infrastructure, hydrocarbons, renewables, defence, aerospace, real estate and digital services.

Operations: Larsen & Toubro generates most of its revenue from Infrastructure & Utilities at about ₹1,348.6b, followed by Technology, Platforms & Services at about ₹565.6b, Energy Conventional at about ₹566.8b, Manufacturing & Products at about ₹148.6b, Financial Services at about ₹189.2b and Development Projects at about ₹49.7b.

Market Cap: ₹5,623.9b

Investors focused on nuclear energy may find Larsen & Toubro interesting because few companies combine a long history in complex EPC projects with in house capability to design and supply reactor grade equipment through its Hi Tech Manufacturing segment. The group has a large order book across infrastructure, energy and digital projects, which supports revenue visibility. Recent offshore and onshore hydrocarbon wins in the Middle East and Oman underline its ability to execute safety critical work that shares many requirements with nuclear projects. On the other side of the ledger, reliance on government and Middle East orders, high external borrowing and a relatively new management team introduce execution and funding risks. That mix of nuclear exposure, project depth and funding questions makes Larsen & Toubro a stock many investors may want to scrutinize more closely.

Bharat Heavy Electricals (BSE:500103)

Overview: Bharat Heavy Electricals is a New Delhi based engineering company that supplies heavy equipment and EPC services for power plants, including steam generators, turbines and reactor support systems that are directly used in nuclear power projects, alongside a broader portfolio across coal, gas, hydro, solar, transport, defence and industrial systems.

Operations: Bharat Heavy Electricals generates most of its revenue from the Power segment at about ₹274.3b, with the Industry segment contributing about ₹85.7b.

Market Cap: ₹1,436.0b

For nuclear focused investors, Bharat Heavy Electricals offers exposure to the heavy equipment and EPC work that underpins reactor construction and long term servicing, backed by a full suite of steam generators, turbines and reactor related systems. Recent quarterly numbers show the company reporting a profit with higher revenue and positive EPS. The trade off is a premium valuation, governance considerations such as a lack of independent directors and an unstable dividend record, in a capital intensive, project driven business. For investors weighing nuclear infrastructure exposure, Bharat Heavy Electricals presents a mix of opportunity and execution risk that may warrant closer examination.

Bharat Heavy Electricals looks like a nuclear infrastructure story where heavy equipment strength meets premium pricing and governance questions. Read the 2 key rewards and 1 important warning sign to see what the market might be missing next.
