Polar Power is trading 5.26% up after-hours at $1.20, versus the regular-session close of $1.14; no company announcement directly explaining it was identified. - On October 6, Solidion said it would not raise its offer for Polar Power’s assets after the board rejected it, describing the company as “severely distressed.” - The announcement reported no stock-price reaction and did not link the news to the after-hours gain. - Broader indices rose during Tuesday’s session, but that alone does not establish the move’s cause.
