Celestica Inc. CLS

CLS Company Overview

Celestica Inc. is a global provider of design, manufacturing, and supply chain solutions, operating primarily in the electronics manufacturing services (EMS) and product lifecycle solutions industries. The company supports original equipment manufacturers (OEMs) across complex, high-reliability sectors, including communications and enterprise, aerospace and defense, industrial, healthtech, and capital equipment. Celestica’s core value proposition centers on delivering end‑to‑end solutions that span design, engineering, advanced manufacturing, and aftermarket services for mission‑critical electronic and electromechanical products.

The company generates revenue primarily through two business segments: Advanced Technology Solutions (ATS) and Connectivity & Cloud Solutions (CCS). Celestica serves leading global technology companies and industrial OEMs, positioning itself as a partner for low‑volume, high‑complexity products rather than commoditized mass electronics. Founded in 1994 as a manufacturing arm of IBM, Celestica became an independent public company in 1996 and has since evolved from a traditional contract manufacturer into a diversified solutions provider focused on higher‑margin, engineering‑intensive markets.
