Nuclear Power Is Back, But Only a Few Stocks Have Customers Signed

The article compares nuclear-energy companies’ customer commitments, contracts, operating assets and licensing status. Cameco reported uranium sales contracts covering about 230 million pounds at the end of 2025; Centrus finalized terms for a $900 million DOE award, and BWX announced more than $1.4 billion in naval nuclear contracts. Constellation and Vistra have signed 20-year power agreements, while Oklo and Nano Nuclear still lack approval to build or operate reactors; Oklo, NuScale and Nano Nuclear shares were down about 80%, nearly 86% and about 68%, respectively, over the past year.

Analysis

The investable distinction is not “nuclear exposure” but where cash flows sit on the path from demand to delivery. CEG and VST monetize licensed generation now; BWXT’s naval backlog is comparatively insulated from data-center project timing. CCO (TSX) and LEU offer fuel-cycle exposure, but their payoff differs: conventional uranium contracting is nearer-term, while HALEU scale-up depends on funding, commissioning and advanced-reactor deployment. Treating these as one theme obscures meaningful timing and execution risk.

A second-order effect of long-term data-center offtake is reduced merchant supply: taking existing nuclear output out of the open market can tighten residual regional power balances and support other generators’ scarcity value. Conversely, fixed-price contract economics may surrender some upside if power prices spike; PPA price, escalation, volume shape and retained merchant exposure matter more than headline duration. Hyperscaler commitments are not proof that early-stage designs will be licensed, financed or built. The reported share-price declines in OKLO and SMR do not by themselves make either cheap; dilution and licensing setbacks can overwhelm demand optionality.

Over the next 1–3 months, watch conversion of frameworks/LOIs into binding offtake, NRC construction/operating milestones, DOE award execution and fuel-capacity timelines. Over 6–18 months, the thesis broadens only if projects reach permits, financing and credible delivery schedules. Falsifiers: stalled licensing or customer conversion; adverse PPA economics; repeated outage/delivery slippage; or lower regional power prices that weaken the scarcity premium. Valuation and contract economics are not provided, so favor relative exposure over an outright sector call.

Key Decisions for Investors

• Prefer a relative-value long in established cash-flow or contracted-execution exposure (CEG, VST, BWXT) versus a basket of pre-commercial developers (OKLO, SMR, NNE), sized conservatively. The asymmetry is improved revenue visibility on the long side; the short side can rebound sharply on licensing or customer news, so avoid an unhedged, concentrated short and verify borrow and valuation first.
• For a fuel-cycle expression, consider CCO (TSX) for conventional uranium contracting and LEU for HALEU capacity optionality as separate positions, not interchangeable beneficiaries. Add only against evidence of funded capacity expansion and customer delivery schedules; DOE execution delays or capex overruns invalidate the LEU leg.
• Do not chase hyperscaler-PPA headlines in CEG/VST without checking contract pricing, escalation, delivered volume and retained merchant exposure. These terms determine whether the agreements add durable earnings or trade away scarcity upside; compare subsequent disclosures with regional power-price and capacity-market trends.
• Alert/watch: treat OKLO, SMR and NNE as milestone-driven options rather than near-term power suppliers. Reassess on a commercial construction/operating approval, binding customer contract, and credible fuel and financing plan; any one headline alone is insufficient.
