Centrus Energy is trading at $115.35, up 4.98% in pre-market, with no verified October 21 company-specific announcement directly explaining the move. - Centrus announced its acquisition of Westerman for approximately $116 million on October 19; available coverage tied that news to an earlier reaction, not this pre-market gain. - The Nasdaq’s supplied +0.68% move offers supportive market context but does not establish the cause of Centrus Energy’s rise.
