Four consecutive earnings beats averaging 36% above consensus and 53% year-over-year revenue growth establish this as an industry standout, but extreme customer and segment concentration means any single relationship disruption could deliver outsized damage to the thesis.

About Celestica, Inc.
About Celestica, Inc.
Celestica's top 10 customers accounted for 79% of total revenue in fiscal 2025, up from 73% in 2024 and 64% in 2023, while three CCS customers individually exceeded 10% of consolidated revenue at 32%, 14%, and 12%. CCS segment revenue reached $9.19 billion in 2025, a 42% increase over 2024, driven by hyperscaler data-center build-outs. Hardware Platform Solutions revenue grew 81% year-over-year, reaching 41% of total revenue.
Celestica earns revenue across two segments with distinct margin profiles. The CCS segment — serving cloud providers, hyperscalers, digital-native companies, and hardware OEMs — manufactures networking switches, optical systems, servers, and data-center racks, with programs characterized by larger volumes and higher margins than ATS. The company's HPS business within CCS commands a premium margin because Celestica participates in product design as an ODM, rather than solely manufacturing to customer specifications. The ATS segment covers Aerospace and Defense, Industrial, HealthTech, and Capital Equipment markets. Supply chain is global, with the majority of electronic components originating from Asian countries. Capital expenditures in 2026 are anticipated at approximately $1 billion — about 6% of currently anticipated revenue — a significant escalation above the historical 1.5% to 2.0% range, to support hyperscaler capacity expansion.
Show full overview
Customer concentration is Celestica's most explicitly quantified risk. The three largest CCS customers — at 32%, 14%, and 12% of consolidated revenue in 2025 — are hyperscalers whose AI investment cycles, access to specialized components such as accelerators, and data-center power procurement decisions directly govern program volumes. The 10-K notes these customers may slow, scale down, or cancel programs if regulatory constraints, power shortages, or shifts in AI investment strategy materialize, and there is no assurance the company can replace lost business quickly.
