The 2 Best Nuclear Energy Stocks to Buy Right Now

The article argues that AI-driven data center demand is accelerating interest in small modular reactors, with BWX Technologies and Rolls-Royce highlighted as lower-risk public plays. BWX’s BANR is a 75 MW data-center-focused design, while Rolls-Royce’s SMR is a larger 470 MW prototype selected in the U.K.’s Great British Nuclear competition and supported by an agreement with Czech utility ČEZ. Both companies are presented as fundamentally strong because their existing businesses generated 2025 revenue growth of 18% to $3.19 billion for BWX and 12.15% to $21.21 billion for Rolls-Royce, alongside rising EPS.

Analysis

The market is likely underappreciating that the near-term value in nuclear for AI is not the reactor headline but the regulatory, manufacturing, and fuel-supply moat around deployability. BWXT is better positioned than most “SMR names” because it is already embedded in a defense-grade quality system, which shortens the credibility gap with hyperscalers and public utilities that cannot afford first-of-a-kind execution risk. That makes BWXT a cleaner way to express the theme than pure-play developers, where financing risk and permitting slippage can compress multiples long before first revenue.

The second-order winner is the adjacent supply chain: specialty metals, fuel fabrication, control systems, and long-cycle engineering services should see earlier monetization than reactor operators. If data-center buyers pursue behind-the-meter generation, they will likely favor vendors that can deliver standardized modules plus long-term service contracts, which should expand lifetime gross margin even if initial hardware economics are modest. The bigger risk is that the “AI nuclear” story becomes a 3-5 year order-book narrative rather than an 18-month earnings catalyst; many buyers will sign MOUs before final investment decisions, creating headline momentum without cash flow.

Contrarianly, the consensus may be too focused on eventual reactor output and not enough on grid interconnection constraints and utility politics. If utility-scale power prices normalize or data-center demand growth moderates, the urgency for on-site SMRs could fade, especially for larger systems that are easier to site but slower to approve. Conversely, BWXT’s smaller design has a better chance of matching the actual incremental load profile of data centers, which makes it more asymmetric if the theme re-accelerates on another AI capex leg.

Rolls-Royce is a higher-beta, less direct expression: its SMR option value is meaningful, but the equity is already carrying multiple embedded narratives, so incremental upside may be capped unless project milestones de-risk sharply. The cleaner tactical setup is to own the company with the most credible first-mover industrialization advantage and avoid paying for broad nuclear enthusiasm across the entire complex.

Key Decisions for Investors

• Long BWXT on a 6-12 month horizon: prefer a staged entry on pullbacks, targeting a 15-25% upside re-rate if AI data-center SMR demand converts from MOUs to funded orders; stop if permitting or cost inflation pushes commercialization materially beyond 2028.
• Relative value: long BWXT / short a basket of unprofitable SMR developers for a 3-6 month horizon; the trade benefits from capital scarcity and execution discount widening if rates stay elevated and project finance remains tight.
• Avoid chasing RYCEY here; if initiating, use a small call spread instead of common stock for 6-12 months to capture milestone-driven upside while limiting valuation compression risk from its more crowded narrative.
• Watch for a second-order long in nuclear supply-chain beneficiaries only after reactor procurement contracts are announced; until then, keep exposure concentrated in BWXT rather than broadening prematurely.
• If BWXT rallies on headline AI demand without order conversion, trim into strength and wait for evidence of booked backlog; the key risk/reward inflection is contract signature, not commentary.
