Celestica Inc.

The business

Two segments: Connectivity & Cloud Solutions (CCS) — servers, storage and high-speed networking switches for hyperscale data centers — and Advanced Technology Solutions (ATS) — aerospace, defense, industrial, healthtech and capital equipment.

Its Hardware Platform Solutions unit designs and builds custom networking/compute hardware for a small set of large cloud customers; reports in US dollars.

The AI/data-center wave has made CCS the growth engine, driving both revenue and a valuation re-rating.

The moat

Deep engineering and qualification relationships with a few hyperscalers create high switching costs on custom platforms.

Scale, supply-chain execution and design capability differentiate it from commodity contract manufacturers.

Concentrated demand for AI networking gear gives near-term pricing and volume leverage.

Financial snapshot

Most recent reported period : FY2025 (ended Dec 31 2025); revenue/cash-flow TTM to Jun 30 2026. Figures reflect the review date — confirm current numbers before acting.

Free cash flow yield & sustainable growth

Free cash flow yield : ≈1.4%TTM free cash flow US$519M ÷ market cap US$38.02B ≈ 1.4%.

Operating cash flow surged +73.5% on the revenue boom, but FCF grew only +13.2% as capex jumped +211%.

EMS/hardware margins are structurally thin, so cash conversion is capital-intensive during the build phase.

FCF could inflect higher once the AI-capacity capex cycle normalizes — or stay pinched if the arms race continues.

Valuation & what to watch

FCF yield only ~1.4% — free cash flow lags because capex more than tripled to fund AI capacity, and the market cap has re-rated ~70% higher.

P/E ~38.6x (GAAP net income flattered by tax items) prices in continued hyper-growth; adjusted profitability is lower than the headline suggests.

This is a momentum/growth valuation, not a value one — the multiple leaves little margin for a demand air-pocket.

Dividend

Pays no dividend. All capital is reinvested into capacity and, at times, share buybacks; income investors get nothing here.

Risks & the bear case

• Heavy customer concentration — a handful of hyperscalers drive CCS; a single order cut would hit hard.
• Cyclical, thin-margin manufacturing dressed as a growth stock; AI-capex could slow or digest.
• Rich valuation (P/E ~39, FCF yield ~1.4%) leaves large downside if growth decelerates.
• GAAP earnings are flattered by tax items; look at adjusted figures and free cash flow for the real picture.
• Tariffs, component supply and inventory swings add operational volatility.

Recent developments

Stock roughly re-rated ~70% over the past year on AI data-center demand; shares near US$371.

FY2025 revenue US$12.39B (+28.5%) and TTM revenue US$15.59B (+47.3%) as CCS/networking accelerated.

Capex more than tripled (TTM ~US$625M) to add AI hardware capacity, compressing free cash flow to ~US$519M.

Management repeatedly raised guidance through the AI cycle; consensus remains bullish (though targets are opinion).

Verdict

Celestica has transformed from a low-multiple contract manufacturer into an AI-infrastructure favorite, with revenue and operating cash flow growing explosively. The catch for a free-cash-flow lens: FCF yield is only ~1.4% because capex is soaring and the equity has re-rated to ~39x earnings — you are paying up for continued hyperscaler demand. The upside is real if the AI build-out persists; the risk is customer concentration and a rich price with little cushion.
