NuScale Power (SMR) Q4 2025 earnings review
Massive Dilution Funds Non-Binding Pipeline as Core Revenue Fades
NuScale ended FY25 with a fortress balance sheet of $1.3 billion in liquidity, but the quality of this cash is highly questionable. It was built entirely on aggressive shareholder dilution—selling 39.3 million shares in Q4 alone for $750 million. Operationally, the picture is deteriorating. FY25 revenue reversed its growth trend, falling 15% YoY to $31.5 million as the RoPower FEED study wound down, causing gross margins to collapse. Most alarmingly, NuScale recognized a staggering $507.4 million milestone expense to its partner ENTRA1 for a non-binding agreement with TVA. The company is essentially burning severe amounts of equity to purchase a prospective, non-binding commercial pipeline.
🐂 Bull Case
The non-binding agreement with TVA contemplates up to 6 GW of SMR capacity across seven states. If converted to firm orders, this represents the largest nuclear deployment program in U.S. history.
Ending the year with $1.3 billion in cash and investments largely de-risks NuScale's ability to survive the long lead times of nuclear development and fund initial manufacturing operations.
🐻 Bear Case
Paying $507.4 million for 'Milestone 1' of a non-binding term sheet is a massive capital allocation risk, shifting all financial burden onto NuScale shareholders before any firm revenue is secured.
With the RoPower Phase 2 FEED study winding down and no immediate replacement contract signed, NuScale faces a severe revenue cliff in early 2026.
⚖️ Verdict: 🔴
Bearish. While the regulatory moat and cash balance are impressive, the business model is currently acting as a mechanism to dilute shareholders to fund non-binding term sheets for a partner entity. Until a firm, cash-generating power purchase agreement is signed, the $664 million net loss and 159% increase in share count eclipse the theoretical pipeline.
Key Themes
ENTRA1 Partnership Drives Massive Cash Burn
In prior quarters, analysts fiercely questioned the upfront payments to ENTRA1. The FY25 results validate these fears: NuScale expensed a staggering $507.4 million for 'Milestone Contribution 1' under the Partnership Milestone Agreement (PMA). This caused G&A expenses to explode from $75.9 million in FY24 to $609.8 million in FY25. Management is burning hundreds of millions in equity for a non-binding collaborative agreement, which contradicts previous narratives of a 'capital-light' go-to-market strategy.
Relentless Shareholder Dilution
To fund the ENTRA1 milestones and offset accelerating cash burn, NuScale aggressively tapped its At-The-Market (ATM) program. In Q4 2025 alone, the company issued 39.3 million shares to generate $750 million. Class A shares outstanding ballooned from 122.8 million at the end of 2024 to 318.4 million at the end of 2025—a 159% dilution in a single year.
Revenue Reversing and Margins Collapsing
Despite management calling 2025 a 'breakthrough year', the core financials deteriorated. Revenue decelerated by 15% YoY to $31.5 million as the Fluor FEED Phase 2 engineering services for the RoPower project began winding down. Simultaneously, Cost of Sales surged 300% to $20.0 million due to the nature of the engineering work, crushing gross margins from 86.6% in FY24 to 36.3% in FY25. This contradicts the positive commercial narrative, showing a company struggling to replace its only active revenue stream.
TVA 6 GW Deployment Pipeline
The collaborative agreement with the Tennessee Valley Authority (TVA) is the company's primary commercial anchor. Targeting up to 6 gigawatts of capacity across a seven-state region, this represents massive future upside. If even a fraction of this capacity converts to firm orders, it will validate the ENTRA1 partnership model and provide years of backlog.
77 MWe NPM Regulatory Approval
NuScale widened its competitive moat by receiving U.S. Nuclear Regulatory Commission (NRC) design approval for its uprated 77 MWe NuScale Power Module (NPM). As competitors remain years away from initial certifications, NuScale's technology is the only legally deployable advanced SMR in the United States, giving them a monopoly on near-term deployments.
Macro: Commercial Chemical Plant Decarbonization
Management highlighted a newly released study demonstrating that NPMs can profitably and reliably power commercial chemical plants by providing both electricity and process steam. This expands the Total Addressable Market (TAM) beyond data centers and grid utilities, tapping into the broader macro theme of heavy-industry decarbonization.
Other KPIs
Accelerating significantly from a cash outflow of $108.7 million in FY24. This massive burn rate was entirely driven by the $507.4 million upfront milestone payment to ENTRA1, proving that the current business model is highly capital intensive.
Accelerating from $8.4 million in FY24. The only true bright spot in the income statement, driven by the massive influx of cash from ATM share sales being parked in higher-yielding short-term investments.
Decelerating from $6.9 million in FY24 and $61.0 million in FY23. The company has hit its cost-share caps with the U.S. Department of Energy, meaning NuScale must now fund 100% of its commercialization and operational expenses moving forward.
