## Company history

Celestica traces its origins to an IBM manufacturing unit, began serving non-IBM customers in 1993, and dates its founding to 1994. IBM sold the company in October 1996 to an investor group led by Onex Corporation. [27](https://app.finbar.com/go?id=P112523166)[28](https://www.celestica.com/about-us/history-and-milestones)

Celestica completed its initial public offering in 1998, during a period of rapid acquisition-led expansion. Its 1998 results announcement described eight acquisitions that year, including a merger with International Manufacturing Services that broadened its presence in Asia. [27](https://app.finbar.com/go?id=P112523166)[29](https://corporate.celestica.com/static-files/e92af5f7-61c1-4f54-a192-2434807756c7) In 2006, it sold its plastics injection-molding business. [30](https://corporate.celestica.com/static-files/d5513536-f2c0-4edd-8949-cb9782129e90)

In 2021, Celestica completed its acquisition of Singapore-based PCI Private Limited, adding capabilities to its Advanced Technology Solutions business. [31](https://corporate.celestica.com/news-releases/news-release-details/celestica-completes-acquisition-pci-private-limited) In 2023, Onex ceased to be its controlling shareholder after secondary share offerings and the conversion of its multiple-voting shares. [27](https://app.finbar.com/go?id=P112523166) Celestica acquired NCS Global in 2024, expanding its IT asset management and disposition services.
