Investing.com -- Shares of advanced nuclear company Oklo Inc (NYSE:OKLO) fell 3.4% Tuesday despite regulatory tailwinds that could smooth its path to deployment. The U.S. Nuclear Regulatory Commission (NRC) announced it has accepted Oklo’s Principal Design Criteria (PDC) topical report for formal review under an accelerated timeline. “This is a reflection of the work by the Oklo team, and the NRC’s commitment to timely oversight,” said Oklo co-founder and CEO Jacob DeWitte. Analyst Dimple Gosai explained the downgrade stems from reverse DCF models implying deployments far above company forecasts and unrealistic discount rates relative to sector norms. “We downgrade Oklo (Neutral from Buy) and NuScale (Underperform from Neutral) as valuations now embed deployment ramps and discount rates we view as unrealistic at this stage of SMR adoption,” said Gosai.
