Why Is SMR Stock Gaining Over 5% In Overnight Trading?
NuScale Power Corp. (SMR) shares rose more than 5% in overnight trading after reports, citing The Chosun, that Japan may invest up to $25 billion in NuScale as part of a broader U.S.-Japan investment package. The report also cites potential SMR funding for GE Vernova (GEV) and Hitachi. U.S. officials are considering Tennessee projects and starting licensing.

Why it matters
The immediate trading driver is the reported $25B Japan investment narrative, plus mention of US officials beginning licensing for SMR development and ongoing discussions with South Korea.

Traders are likely repricing NuScale’s funding and policy tailwinds based on a specific reported investment figure, even though deal confirmation is not shown.
What to watch
Key details like timing, equity vs. debt structure, project selection, and regulatory/licensing milestones are not provided, so the market may over-discount the probability and magnitude of actual cash flows.
Background

Ticker impact
NuScale Power shares rose over 5% overnight on reports Japan plans to invest up to $25B in its small modular reactors.
