With inflation still a key focus and energy costs closely watched across regions, many investors are looking at the Nuclear Energy Stocks screener as a way to focus on companies tied to uranium supply, enrichment and reactor operations for reliable power. This article highlights 3 notable stocks from that screener, helping you quickly narrow a broad universe of nuclear opportunities into a more targeted watchlist to research further. ## Marubeni (TSE:8002) **Overview:** Marubeni is a diversified Japanese trading company that buys, sells and invests across a wide range of sectors, from food and agriculture and consumer goods to energy, chemicals, metals, power infrastructure and financial services. **Operations:** Marubeni generates most of its revenue from Food & Agri Business at ¥3,720,523m, along with sizeable contributions from Energy & Chemicals at ¥1,365,839m, Metals & Mineral Resources at ¥918,917m, Aerospace & Mobility at ¥691,291m, Lifestyle at ¥644,053m, and several smaller segments including Power & Infrastructure Services at ¥485,323m. **Market Cap:** ¥7.5t Marubeni gives you exposure to nuclear power, LNG and broader energy infrastructure within a diversified trading house that also has deep roots in food and agriculture. Revenue and earnings are forecast to grow, and analysts are aligned on meaningful upside potential, even though the current share price sits above Simply Wall St’s DCF estimate. At the same time, high debt levels, an unstable dividend track record and relatively new management and board teams mean the stock is not without execution and funding risk. Recent LNG deals, governance changes and an expanded buyback plan add extra moving parts that investors who care about nuclear energy and energy security may want to understand more closely before deciding how it fits into their portfolio. Marubeni’s broad energy reach, from nuclear exposure to LNG and infrastructure, could be masking a very different risk return profile than the headline valuation suggests. It is therefore worth scanning the 3 key rewards and 2 important warning signs 8002 Discounted Cash Flow as at Jun 2026 ## Hitachi (TSE:6501) **Overview:** Hitachi is a Japanese industrial and technology group that supplies digital systems, energy and power grids, railway and mobility solutions, and a wide range of industrial equipment and services for customers worldwide. **Operations:** Hitachi generates most of its revenue from Connective Industries at ¥3.26t, Digital Systems & Services at ¥2.94t, and Energy at ¥3.22t, with smaller contributions from Mobility at ¥1.32t and Others at ¥0.53t, partly offset by corporate eliminations of ¥0.69t. **Market Cap:** ¥20.45t Hitachi stands out in the nuclear and power grid theme because it combines critical energy infrastructure, including nuclear and clean energy, with digital and AI services tied to platforms like Lumada and partnerships with OpenAI, Google Cloud, Intel and Anthropic. Earnings grew 30.3% over the past year, while net margins have improved to 7.6%. At the same time, the stock trades on a premium P/E multiple, relies heavily on external funding and carries project and execution risk in areas such as China elevators and large capex programs. For investors focused on nuclear, grid stability and AI linked infrastructure, there is more to unpack in Hitachi’s evolving story beyond the headlines. Hitachi’s mix of nuclear, grids and AI-linked services could mean the real story is how growth potential stacks up against that premium P/E.

TSE:6501 P/E Ratio as at Jun 2026 ## Mitsubishi Heavy Industries (TSE:7011) **Overview:** Mitsubishi Heavy Industries is a Japanese industrial group that builds and services large scale energy systems, nuclear and thermal power plants, aerospace and defense equipment, ships and machinery, as well as air-conditioning and factory equipment worldwide. **Operations:** Mitsubishi Heavy Industries generates most of its revenue from Energy Systems at ¥2,062.6b, Aircraft, Defense & Space at ¥1,393.9b, Plants & Infrastructure Systems at ¥880.9b and Logistics, Thermal & Drive Systems at ¥630.8b, with smaller contributions from Others and corporate eliminations. **Market Cap:** ¥12.16t Mitsubishi Heavy Industries brings together nuclear power, carbon capture and gas turbine technology with defense and aerospace, giving you exposure to energy transition and security themes in one stock. Earnings and net margins have recently improved, and analysts see further gains, but the P/E sits well above the wider machinery sector and the company relies fully on external borrowing, which raises funding and interest rate risk. Order backlog at a record level, growth in next generation energy and rising defense and aviation activity all support revenue visibility, yet currency swings, working capital needs and uneven segment profitability could pressure cash flows. Understanding how these cross currents feed into future margins, payout decisions and valuation is crucial before deciding where Mitsubishi Heavy Industries belongs on your nuclear watchlist. Mitsubishi Heavy Industries’ mix of record backlog, nuclear projects and defense work could be masking where the real earnings power sits. See how the analysis report for Mitsubishi Heavy Industries connects that upside with the funding risks investors often miss.
