UBS Cuts NuScale Power to Sell on Timeline, Cash Burn

UBS downgraded NuScale Power (NYSE:SMR) to Sell from Neutral, slashing its price target to $6.00 from $10.00 due to extended construction timelines, cash burn projections, and a lack of firm customer commitments.

The downgrade highlights growing scrutiny over the commercialization path for small modular nuclear reactors. While the nuclear sector attracts interest as data centers demand carbon-free power, financial analysts are increasingly separating near-term capital requirements from long-term industry potential.

Projected Cash Burn and Capital Needs

UBS forecasts that NuScale Power will experience approximately $700 million in cumulative cash burn from 2026 through 2028. This capital drain reflects the heavy upfront costs associated with engineering, regulatory compliance, and initial deployment phases of nuclear technology before construction achieves steady-state revenue generation.

To address ongoing funding requirements, NuScale Power announced a $750 million at-the-market stock offering program. The capital-raising vehicle is facilitated through a sales agreement with multiple financial institutions, including UBS Securities and B. Riley Securities.

Diverging Wall Street Estimates

Analyst sentiment across Wall Street remains divided regarding how to value early-stage nuclear technology developers facing substantial capital dilution.

• UBS: Downgraded to Sell with a $6.00 price target, emphasizing timeline risks and cash burn.
• B. Riley: Maintained a Buy rating while lowering its price target from $19.00 to $15.00, citing an increased share count and a valuation reset across the sector.

The divergence between firms largely stems from differing assumptions about how quickly equity dilution from stock offerings will impact per-share value relative to future deployment milestones.

Partner Discussions and Utility Pipelines

Commercial progress hinges on securing binding agreements with utility providers capable of financing multi-billion-dollar energy projects. NuScale's partner, ENTRA1 Energy, is currently progressing in discussions with the Tennessee Valley Authority regarding a potential power purchase agreement for small modular reactors in Tennessee.

What is at stake for NuScale and other nuclear technology developers is the ability to bridge the multi-year gap between experimental design approval and operational revenue. Without binding offtake agreements and steady utility adoption, firms face heavy reliance on equity markets to fund operations, risking shareholder dilution as construction timelines extend.
