Listen to the news

With bond markets reacting to shifting rate expectations, energy price risks and mixed growth signals across regions, investors are paying close attention to sources of reliable power. Nuclear energy stocks sit at the intersection of energy security and low carbon generation, and the Nuclear Energy Stocks screener focuses specifically on companies involved in uranium supply, fuel processing and reactor operations. This targeted approach can help you sort through a crowded market and focus on listed stocks linked to nuclear power. In this article, you will see 3 stocks from the screener that many investors are watching closely.

Larsen & Toubro (BSE:500510)

Overview: Larsen & Toubro is a Mumbai headquartered engineering and construction group that delivers large infrastructure, energy, defence, nuclear and technology projects across India and overseas, from designing and building transport networks and factories to complex refineries, offshore wind assets and smart infrastructure. Alongside EPC work, it also manufactures critical equipment for nuclear and green hydrogen projects, supplies defence and aerospace systems, and runs IT, technology and financial services businesses.

Operations: Larsen & Toubro generates most of its revenue from Infrastructure Projects of ₹1,354,158.9m, followed by IT & Technology Services of ₹545,659.4m, Energy Projects of ₹549,034.8m, Financial Services of ₹178,492.9m and Hi Tech Manufacturing of ₹144,900.1m, with smaller contributions from Development Projects and Others.

Market Cap: ₹5,250.8b

Larsen & Toubro stands out in the nuclear energy theme because its EPC capabilities, order book and hi tech manufacturing directly support reactor, grid and clean energy projects, while its IT and digital arms plug into data centers and AI infrastructure. Investors watching the stock may be drawn to its large order pipeline in infrastructure, hydrocarbons and green projects, coupled with its earnings profile and a P/E that sits below some peer averages, yet still above the broader Indian construction industry. At the same time, heavy exposure to government and Middle East contracts, use of higher risk external borrowings and pressure on project margins mean execution quality and funding costs really matter. The full story around earnings quality, debt and long term nuclear exposure is where this company gets interesting.

Larsen & Toubro’s broad order book across infrastructure, energy and nuclear projects can make its current P/E look like only half the picture. Review the 2 key rewards and 1 important warning sign to see what might be hiding behind those margins and borrowings.

MTAR Technologies (NSEI:MTARTECH)

Overview: MTAR Technologies is a Hyderabad based precision engineering company that manufactures high precision, heavy equipment, components and machines used in nuclear reactors, defence, aerospace, clean energy and other mission critical applications in India and overseas.

Operations: MTAR Technologies generates revenue of ₹8,762.1m from manufacturing high precision and heavy equipment, components and machines.

Market Cap: ₹180.0b

MTAR Technologies catches investor attention in the nuclear energy theme because it supplies critical components for reactors and clean energy systems while also serving defence, space and data center related demand. Revenue and earnings have both moved sharply higher in the latest year, supported by margin improvement and a recent blanket purchase order of about US$238.8m that adds multi year visibility. At the same time, a rich P/S multiple, high working capital needs and reliance on a handful of large customers mean that any slip in execution or order timing can quickly affect cash flow and valuation. The balance between these strong growth drivers and concentrated risks is where the investment debate on MTAR really starts to get interesting.

MTAR Technologies looks like a growth story that could be masking more than it reveals, with that recent US$238.8m blanket purchase order only part of the picture. The analysis report for MTAR Technologies hints at what could really change the risk reward balance for you.

Bharat Heavy Electricals (BSE:500103)

Overview: Bharat Heavy Electricals is a New Delhi based manufacturer that supplies large power plant equipment and complete systems for coal, gas, hydro and nuclear power, as well as solar, rail transport, transmission, defence, aerospace, e-mobility and industrial projects in India and overseas.

Operations: Bharat Heavy Electricals generates most of its revenue from the Power segment at ₹274,273.5m, with the Industry segment contributing ₹85,656.4m.

Market Cap: ₹1,449.6b

Bharat Heavy Electricals is on many investors’ radar because earnings growth has been very strong recently, supported by rising margins, with profit margins at 6.8% compared with 1% a year earlier and earnings growth far above both its own 5 year average and the wider Electrical industry. Large orders in supercritical thermal projects, export contracts and new green hydrogen electrolyzer manufacturing give the company exposure across conventional power, nuclear related work and cleaner energy. However, a high P/E multiple against sector peers, 100% reliance on higher risk external borrowings and a board structure with no independent directors raise questions about how resilient this trajectory could be. The real tension between that growth, the governance set up and funding risk is what investors should look at more closely.

Bharat Heavy Electricals looks like an earnings story that is decoupling from its own past, with margins and growth now front and center. Before you lean too hard into that momentum, the analyst forecasts for Bharat Heavy Electricals could change how you see the next chapter
