FOR IMMEDIATE RELEASE                                                           Friday, June 4, 2004

CELESTICA INC. ANNOUNCES
EXPECTED OFFERING OF DEBT SECURITIES

Amended Credit Facility Also Announced

TORONTO, Canada — Celestica Inc. (NYSE, TSX: CLS), a world leader in electronics manufacturing services (EMS), today announced its intention to sell US$350 million principal amount of senior subordinated notes due 2011, subject to market and other conditions.

The offering is being made pursuant to Celestica's shelf registration statement previously filed with and declared effective by the Securities and Exchange Commission. The net proceeds of the offering of the senior subordinated notes are currently anticipated to be used for the potential repurchases of Liquid Yield Option Notes, or LYONs, and general corporate purposes, including future acquisitions.

Citigroup Global Markets Inc., Banc of America Securities LLC and Deutsche Bank Securities Inc. will act as joint book-running managers for Celestica's notes offering. Full details of the offering, including a description of, and certain risk factors related to, the notes and our business, are contained in a prospectus supplement dated today, which is available from Citigroup Global Markets Inc., Prospectus Department, Brooklyn Army Terminal, 8th Floor, 140 58th Street, Brooklyn, New York 11220.

Celestica also announced today the amendment of its existing US$250 million 364-day revolving term credit facility, which has been increased in size to US$600 million with its maturity extended from October 2004 to June 2007. Concurrent with this amendment and extension, Celestica elected to terminate its US$500 million four-year revolving facility, which would have otherwise matured in June 2005. No amounts are currently outstanding under either of these facilities.

CIBC World Markets and RBC Capital Markets acted as Joint Lead Arrangers, Canadian Imperial Bank of Commerce acted as Administrative Agent, RBC Capital Markets and Banc of America Securities LLC acted as Co-Syndication Agents and The Bank of Nova Scotia acted as Documentation Agent for the amendment and extension.
