BWX Technologies Inc. surged in early New York trading after reporting second-quarter results that beat Wall Street forecasts, reinforcing investor confidence in the nuclear-power supply chain. The Lynchburg, Virginia-based contractor, whose reactors power the U.S. Navy’s submarines and aircraft carriers, said overnight that both profit and revenue topped consensus estimates, buoyed by steady government demand for propulsion systems and related services. The stock jumped about 13% in pre-market dealings to roughly $187, putting it on course for an all-time high and triggering technical “breakout” signals flagged by several market trackers. The upbeat print sparked a broader bid for nuclear-technology equities: advanced-reactor developer Oklo set fresh highs, while NuScale Power and Nano Nuclear Energy also strengthened in early trade. Analysts said BWXT’s results underscore rising interest in nuclear energy as governments seek low-carbon baseload power and secure defense supply lines. The sector has outperformed major indexes this year amid a flurry of contract wins and policy support, and Tuesday’s moves suggested investors remain willing to rotate into specialised nuclear names when industry bellwethers surprise to the upside.
