Winston Score History

The full picture

NuScale Power is an American company that designs small nuclear reactors called Small Modular Reactors, or SMRs. These reactors are much smaller than traditional nuclear power plants and are meant to generate clean electricity for utilities, governments, and industrial customers. NuScale holds the only small modular reactor design currently approved by the U.S. Nuclear Regulatory Commission, which sets it apart from competitors.

NuScale makes money by licensing its reactor technology and earning fees from engineering and development contracts, rather than building or operating power plants itself. The company is based in Portland, Oregon, and has pursued projects in the U.S. and internationally, including partnerships in Europe and Asia. Its main competitive advantage is its regulatory head start, but the company is burning through cash heavily — its operating margin is deeply negative — and its biggest risk is whether customers will commit to building projects at a cost and timeline that makes nuclear power competitive with other clean energy sources.

Revenue declining

NuScale Power Corporation's revenue is actually shrinking. In a growth stock, that removes the core investment thesis. The low Winston Score here may be warranted — unless there's a turnaround story.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
