Celestica (TSX: CLS) will release its first-quarter 2026 financial results after market close on Monday, April 28, with a conference call scheduled for 8:00 a.m. ET on Tuesday, April 29. The print arrives as one of the most anticipated earnings events on the TSX this month. Management issued Q1 guidance of $3.85–$4.15 billion in revenue and adjusted EPS of $1.95–$2.15 — both well above consensus at the time of guidance — and the stock has built significant momentum heading into the release, trading above its 200-day moving average at $294.84. Celestica has now beaten EPS estimates in 100% of quarters over the past two years.

The earnings momentum underpinning Celestica is structural rather than cyclical. The Toronto-based company has repositioned itself as a data centre infrastructure manufacturer, benefiting directly from the AI capital expenditure wave that has seen hyperscalers commit approximately US$650 billion in infrastructure spending for 2026. Celestica’s full-year 2025 revenue reached US$12.4 billion, up 28%, with adjusted EPS climbing 56%. Management subsequently raised its 2026 revenue outlook to US$17 billion, and in March announced a strategic collaboration with AMD on the Helios rack-scale AI platform — with hardware deliveries expected to begin reaching customers in late 2026, adding a concrete near-term revenue catalyst.

For TSX investors, Celestica represents one of the clearest Canadian leverage plays on global AI infrastructure spending. Its Advanced Technology Solutions segment, which serves hyperscaler clients, drives the bulk of growth, while its Connectivity and Cloud Solutions segment provides revenue diversification. Analysts at Simply Wall St have revised their fair value estimate for CLS higher to CA$577.12 on the back of updated revenue growth assumptions. Prior quarterly releases have triggered single-day stock moves ranging from approximately -5.65% to +19.19%, reflecting how much information is packed into each print.

The key metrics to watch in tomorrow’s report are revenue against the $3.85–$4.15 billion guidance midpoint, adjusted EPS relative to the $1.95–$2.15 range, and any update to the 2026 full-year $17 billion revenue outlook. Management commentary on the Helios platform ramp timeline and hyperscaler order visibility will be equally important.

A beat-and-raise would reinforce Celestica’s premium multiple; any guidance cut, particularly tied to AI spending caution among U.S. customers, would trigger a sharp correction. The TSX tech subindex has been one of the few sector bright spots this week, and Celestica’s results will set the tone for Canadian technology names heading into May.
