Advanced Nuclear Names in Focus After Analyst Note Splits Reactor Developers
A research note from investment bank Piper Sandler drawing distinctions within the nuclear power sector put a spotlight on the next-generation reactor developers this week, and shares of Oklo and NuScale Power moved in different directions in subsequent trading.
Oklo, the Silicon Valley-based developer of compact fast reactors, traded at $42.78, down about 1.7% from its previous close of $43.51, valuing the company at roughly $8.0 billion. NuScale Power, which designs small modular reactors, or SMRs — factory-built units intended to be assembled on site rather than constructed as large traditional plants — moved sharply higher, changing hands at $11.18, up 15.5% from a prior close of $9.68, for a market capitalization near $4.6 billion.
The divergence underscores how varied the advanced nuclear group has become. While the companies are often lumped together as an emerging SMR cohort, their business models, regulatory paths, and timelines to first revenue differ considerably. Oklo is pursuing so-called fast reactors, which use a different fuel and cooling approach than conventional light-water designs, and has positioned its initial deployments around data-center and industrial power purchase arrangements. NuScale, by contrast, is further along in the formal licensing process with the U.S. Nuclear Regulatory Commission, having already secured design approval for its light-water-based module technology.
Analyst commentary that separates such companies by fundamentals — rather than treating the sector as a single trade — can drive outsized daily moves in the group, which has historically been sensitive to news flow, federal funding decisions, and hyperscaler interest in nuclear energy for powering artificial intelligence infrastructure. Pre-revenue reactor developers tend to trade on expectations and policy signals more than on financial results, which amplifies volatility around ratings actions.
Broader context remains favorable for the sector: recent federal support for advanced reactor licensing, renewed interest in nuclear power among large technology companies seeking around-the-clock carbon-free power, and state-level moves to preserve existing nuclear capacity have all contributed to renewed investor attention. At the same time, developers still face the challenge of translating designs into licensed, on-budget construction — a step no Western SMR developer has completed commercially at scale yet.
What to watch
- NuScale’s upcoming earnings report and any updates on deployment partners and cost estimates for its Voygr plant configurations.
- Oklo’s progress on NRC licensing milestones and details of customer agreements tied to its first Aurora powerhouse.
- Further analyst coverage differentiating advanced nuclear developers, and any new federal funding or licensing announcements.
