On June 3, Celestica fell 3.58% in after-hours trading, trading at 442.95 USD/share, with trading volume of 2.9455 million USD. The stock also declined 3.87% during regular trading hours earlier in the session, suggesting sustained selling pressure throughout the day.

The pullback follows a sharp rally of over 21% accumulated over the prior two trading days. The surge was driven by the company raising its full-year revenue guidance to 19 billion USD for the fiscal year and announcing a major 1.6T Ethernet CPO switch order. While institutions broadly acknowledged strong AI market demand and long-term growth potential from CPO switches and ASIC server projects, the stock appears to be experiencing profit-taking after the rapid advance that had pushed shares to historic highs.

Within the Electronic Manufacturing Services sector, the broader group showed muted activity. Among individual stocks, Flex Ltd down 0.02%, Fabrinet down 0.69%, Jabil Circuit down 0.01%, TE Connectivity flat, and TTM Technologies down 0.32%.
