What does Celestica do?
Celestica designs and manufactures hardware for other companies, listed in both New York and Toronto. Its Connectivity & Cloud Solutions (CCS) segment builds the custom network switches, AI/ML compute systems, servers, and storage that hyperscalers deploy at scale, including original-design hardware sold through its Hardware Platform Solutions (HPS) line; Advanced Technology Solutions (ATS) serves aerospace and defense, industrial, healthtech, and capital-equipment customers (Celestica, Apr 27, 2026). In Q1 2026 CCS generated $3.24 billion of revenue at an 8.6% segment margin while ATS contributed $0.81 billion at 6.0%.
How is AI driving Celestica’s business?
Every AI cluster a hyperscaler deploys needs racks of switches and servers built by someone, and Celestica has become one of the principal builders. CCS revenue grew 76% year over year in Q1 2026, with HPS, the original-design switching and compute line, up 63% to about $1.7 billion (Celestica, Apr 27, 2026). The momentum compounds: after closing 2025 with Q4 revenue up 44% and setting a $17.0 billion outlook for 2026 (Celestica, Jan 28, 2026), the company raised that outlook to $19.0 billion just one quarter later. President and CEO Rob Mionis tied the raise to demand visibility:
“We continue to see accelerating growth from our CCS customer base, alongside increasing profitability in both our CCS and ATS segments. Driven by this momentum, we are raising our 2026 annual outlook to $19.0 billion in revenue and $10.15 in adjusted EPS. Our outlook for 2027 also continues to strengthen from just 90 days ago, supported by new program wins as well as improved forecast visibility with our customers.”

What did Celestica report most recently?
In Q1 2026 (the quarter ended March 31, 2026), Celestica posted revenue of $4.05 billion, up 53% from $2.65 billion a year earlier and above its $3.85-4.15 billion guidance midpoint (Celestica, Apr 27, 2026). Adjusted EPS of $2.16 beat the high end of the $1.95-2.15 guidance range, against $1.20 a year earlier; GAAP EPS was $1.83. Adjusted operating margin reached 8.0%, a company record, and Celestica repurchased $20 million of shares in the quarter.
What is Celestica’s guidance?
Celestica raised its 2026 annual outlook to $19.0 billion of revenue (from $17.0 billion), $10.15 of adjusted EPS (from $8.75), and an 8.1% adjusted operating margin, while keeping its $500 million free cash flow outlook; Q2 2026 was guided to $4.15-4.45 billion of revenue and $2.14-2.34 of adjusted EPS (Celestica, Apr 27, 2026). Management also expects 2027 revenue growth to exceed 2026’s roughly $6.5 billion increase. The next report is expected around late July 2026, calendar-estimated.
What are the risks for Celestica?
- Hyperscaler concentration. A handful of cloud customers drive CCS, now 80% of revenue; one insourcing decision or program loss moves the whole growth story.
- Manufacturing margins. Even a record adjusted operating margin is 8.0%; the EMS model leaves little cushion if pricing or mix turns.
- Competition for AI programs. Foxconn, Quanta, Wiwynn, and other ODMs contest every hyperscaler design win.
- AI capex cyclicality. The raised outlook assumes hyperscaler budgets keep climbing; a digestion phase would hit both volume and the premium HPS mix.
