The beat was big. The outlook was the story.

$$CLS ( ▼ 4.84% ) jumped 11.75% to $290.55 on Monday after Celestica reported third-quarter results that cleared its own guidance on every line — and then told investors next year will be nearly twice this one. Revenue came in at $5.83 billion, up 83% from $3.19 billion a year ago and above the company's $5.25–5.55 billion guide. Adjusted EPS of $3.30 more than doubled year over year and beat the $2.88–3.08 range management had set.

The engine is the CCS segment — the cloud and AI infrastructure business — which grew 102% to $4.87 billion, with hyperscaler hardware platforms up roughly 70% to about $2.3 billion. Celestica builds the networking switches and data-center hardware that the largest cloud providers and frontier AI labs are racing to deploy, and the quarter reads like a direct transcript of that capex cycle.

Bar chart of Celestica revenue outlook: $21 billion raised guide for fiscal 2026 versus a $40 billion initial outlook for fiscal 2027

The initial 2027 outlook calls for roughly 90% growth on top of a year that already grew.

The numbers behind the double

  • Q4 2026 guide: revenue of $6.275–6.575 billion and adjusted EPS of $3.37–3.57.

  • Full-year 2026 raised: revenue to $21.0 billion (from $20.5 billion) and adjusted EPS to $11.55 (from $11.30).

  • Initial 2027 outlook: revenue of $40.0 billion — up roughly 90% — with adjusted EPS of $21.50, a 9.0% adjusted operating margin, and $1.5–2.0 billion of capex. Management added that customers' 2028 demand forecasts are "meaningfully higher" than even the 2027 plan.

  • Capital returns: a new buyback of up to 2.5% of the float planned for Q4, following an 11.1-million-share offering that raised $3.45 billion gross in August.

Why the stock had room to jump 12%

Context matters here: Celestica entered Monday around $260, down roughly 45% from its 52-week high of $474, after October's broad unwind in AI-infrastructure names. The market had been pricing in a capex digestion phase. A quarter that accelerated to 83% growth, plus a 2027 outlook that nearly doubles revenue again, is the opposite of digestion — and the squeeze back up was proportional to the fear that had built in.

Not everything in the print was clean. Free cash flow guidance for 2026 was cut to $460 million from $600 million on working-capital needs — ramping hardware this fast ties up cash. GAAP operating margin fell to 7.9% from 10.2% a year ago on mix, even as the adjusted operating margin improved to 8.5%.

What we're watching

  • Tuesday morning. The earnings call doubles as Celestica's 2026 Investor and Analyst Day (October 27, 8:00 a.m. ET), where the 2027 and 2028 demand detail gets filled in.

  • Customer concentration. A handful of hyperscalers and AI labs drive the growth. Any capex pause at one of them hits hard — the 45% drawdown from the high shows how sensitive the multiple is to that sentiment.

  • Cash conversion through the ramp. The FCF cut plus $1.5–2.0 billion of 2027 capex means the quality of the growth is measured in working capital, not just revenue.

  • Execution risk. Nearly doubling revenue in a single year is an operational feat before it is a financial one.
