3 AI-Powered Nuclear Energy OEMs With More Upside Post Solid Q2 Results

Leading nuclear energy original equipment manufacturers (OEMs) Mirion Technologies (MIR), BWX Technologies (BWXT), and GE Vernova (GEV) reported robust Q2 2025 earnings, surpassing estimates and raising full-year 2025 guidance. This strong performance is driven by escalating demand for nuclear power, primarily fueled by the energy-intensive AI data center boom and significant U.S. government initiatives targeting a four-fold increase in nuclear capacity to 400 GW by 2050. These companies, with their specialized product portfolios and strong backlogs, are strategically positioned to capitalize on the long-term growth trajectory of the nuclear sector, including advancements in small modular reactors (SMRs).

Analysis

The nuclear energy sector is experiencing a significant tailwind, primarily driven by the escalating power demands of artificial intelligence data centers and supportive government policy, exemplified by the U.S. target to quadruple nuclear capacity to 400 GW by 2050. Three key original equipment manufacturers (OEMs) are capitalizing on this trend, as evidenced by their strong second-quarter 2025 performance. Mirion Technologies (MIR) exceeded estimates with a 4.2% revenue beat and raised its full-year revenue growth outlook to 7-9%, supported by its critical role in radiation safety and digital solutions for next-generation reactors. BWX Technologies (BWXT) delivered a substantial earnings beat with adjusted EPS of $1.02 versus a $0.79 consensus, driven by robust government and commercial demand that boosted its backlog by 70% year-over-year to $6 billion, with a quarterly book-to-bill of 2.2. GE Vernova (GEV) also surpassed expectations and significantly raised its free cash flow guidance, leveraging its GE Hitachi joint venture to lead in the small modular reactor (SMR) market with its BWRX-300 model, which has multiple international deployment agreements. The strong earnings, upwardly revised guidance, and strategic positioning in high-growth areas like SMRs across all three companies underscore a robust fundamental outlook, suggesting sustained momentum despite recent stock price appreciation.

Key Decisions for Investors

• Given the powerful secular growth drivers from AI-related energy demand and government policy, investors should view these nuclear OEMs as core long-term holdings for exposure to the energy transition and infrastructure build-out.
• Investors can differentiate based on specific risk appetites and strategic focus: BWXT offers robust, de-risked growth through its $6 billion government-backed backlog, GEV provides high-growth potential via its leadership in the emerging SMR market, and MIR presents a stable, services-oriented play on mandatory safety and digital upgrades across the entire nuclear lifecycle.
• Despite strong fundamentals and raised guidance, the current Zacks Rank #3 (Hold) and significant year-to-date stock appreciation suggest that investors should monitor valuations closely and consider building positions during any potential market or sector-specific pullbacks, while tracking SMR deployment milestones and contract wins as key performance indicators.
