As of 4:33 p.m. ET, Celestica’s gains are fading slightly. Shares are up 8.5%, but that’s down from gaining nearly 14% earlier. The company has had an excellent 2025 and expectations were high headed into earnings, so that could be leading some investors to trim their positions after hours.

Revenue was $3.19 billion, above the $3.04 billion consensus estimate. Adjusted EPS was $1.58, above the $1.49 consensus estimate.

Celestica raised its 2025 annual revenue outlook to $12.2 billion and adjusted EPS to $5.90, citing continued strong demand and execution. The company also provided a 2026 outlook with expected revenue of $16.0 billion and adjusted EPS of $8.20, supported by investments in AI data center infrastructure.

“We achieved very strong results in the third quarter, with revenue of $3.19 billion and non-GAAP adjusted EPS* of $1.58, representing growth of 28% and 52%, respectively, each exceeding the high end of our guidance ranges,” said CEO Rob Mionis, reflecting a very bullish tone on the quarter.
