C3is shares surge 27.92% after-hours on better-than-expected Q4 adjusted EPS of $4.10 vs. $24.90 loss last year.

C3is Inc. surged 27.92% in after-hours trading following the release of its fourth-quarter adjusted earnings per share (EPS) of ($4.10), a significant improvement from ($24.90) in the prior-year period. The results, reported by TipRanks and GlobeNewswire, indicated a narrowing loss, signaling improved operational performance and potentially stronger cost management or revenue trends. The stock's sharp rebound aligns with the positive earnings surprise, as investors likely interpreted the reduced deficit as a sign of stabilization or recovery in the company's business model. The announcement of the earnings release date 15 days earlier did not immediately move the stock but set the stage for the post-earnings reaction. The after-hours rally reflects market optimism about C3is's ability to mitigate losses in its 2025 fiscal period.
