What Celestica does
Celestica is a Toronto-headquartered, NYSE/TSX-listed (CLS) technology manufacturing services company founded in 1994 that delivers end-to-end design, engineering, manufacturing, supply chain, and after-market services for complex electronics, with a strategic center of gravity in AI infrastructure. Its Hardware Platform Solutions division produces AI-oriented switches (the DS6000-series 1.6TbE Ethernet switches with 102.4 Tbps capacity on Broadcom Tomahawk 6 silicon, plus a 2027-mass-production 1.6T co-packaged optics program), storage platforms (SC6110), compute/rack-scale systems (AMD Helios, OpenAI Jalapeño system integration with Broadcom, Google TPU manufacturing), and a hardened commercial SONiC network operating system — all validated against OCP and Ultra Ethernet Consortium standards.
The company serves seven end markets: Hyperscalers (primary), Enterprise, Communications, Aerospace & Defense, Industrial & Smart Energy, HealthTech, and Capital Equipment. Revenue is generated through three streams: hardware platform sales, design and engineering services, and after-market services, sold via direct enterprise sales to hyperscalers and OEMs and through a channel partner network that includes TD Synnex, ASI Computer Technologies, EPS Global, Stordis, and Apresia. Pricing is quote-based and contract-based on multi-year programs, with deep co-design engagements embedding Celestica into customer silicon and platform roadmaps.
Celestica operates from 40+ locations across North America, Asia, and Europe with 27,000+ employees, and is differentiated from generic EMS/ODM peers by aerospace/defense certifications (AS9100/AS9110, NADCAP, ITAR, CGP, FAA Part 145), medical (ISO 13485) and automotive (IATF 16949, VDA 6.3) credentials, and a $19B FY2026 revenue trajectory built on a ~28% YoY FY2025 base of ~$12.39B. Major M&A history includes Atrenne (2018), PCI Limited (2021, $306M), and NCS Global (2024, $59.6M), with a $876M Fort Worth, TX advanced manufacturing campus and a $300M Richardson, TX expansion currently underway to scale AI data center capacity.
