Shares of Celestica (CLS.TO) surged 7.3% to CA$489.50 on July 30, extending a post-earnings rally that began when the company reported blowout second-quarter numbers on July 27. A broader tech rebound, fueled by strong Microsoft results and renewed AI optimism, added fuel. The question for shareholders: how long can a contract manufacturer sustain hypergrowth before the math gets harder?
Revenue Jumped 62%, and the Company Still Beat Its Own High-End Targets
Celestica's Q2 revenue of $4.70 billion exceeded its $4.15–$4.45 billion guidance range.
GAAP earnings per share hit $3.17 (up from $1.82), while adjusted EPS reached $2.54 (up from $1.39) — an 83% year-over-year increase.
The Connectivity and Cloud Solutions segment — Celestica's data-center hardware arm — jumped 84%, making hyperscaler networking and AI compute the main growth engine. When the division that builds switches, servers, and racks for the world's largest cloud companies accounts for 81% of your revenue, you are, for better or worse, an AI-infrastructure pure play.
Management Raised Its Full-Year Outlook for the Third Time This Year
Celestica lifted its 2026 revenue outlook to $20.5 billion (from $19 billion) and adjusted EPS guidance to $11.30 (from $10.15).
It also bumped its free cash flow target to $600 million and its operating-margin goal to 8.4%. That trajectory — up from an initial $17 billion target in January — signals management sees no letup in orders. But the $20.5 billion target implies roughly $6.35 billion in Q4 revenue at the Q3 midpoint, requiring another sharp sequential acceleration late in the year.
New Customer Wins Could Extend the Runway Into 2027
CEO Rob Mionis told analysts the company expects to ramp next-generation networking-switch programs and has new rack deployments with OpenAI and AMD, both described as "multi-billion-dollar opportunities."
Management expects 2027 revenue growth to exceed the 65% rate projected for 2026, with earnings growing even faster. That is a bold claim for a company whose revenue has already nearly tripled since 2024.
Profit Margins Are Expanding, but Inventory Is Piling Up
Adjusted operating margin reached a record 8.2%, up from 7.4% a year ago — proof the company is capturing more value, not just more volume. Yet inventory swelled by $1.5 billion year-over-year to support scaling , and Celestica did not repurchase any shares, choosing to reinvest in capacity. If demand softens, that inventory becomes a risk, not an asset.
