Celestica After The Run Still Has More Upside

Celestica reported 28% revenue growth and 56% EPS growth in 2025, driven by CCS segment expansion and hyperscaler AI demand. CCS now comprises roughly 74% of revenue, heightening dependence on hyperscaler spending cycles and concentrated customer exposure. Management plans $1.0 billion in CapEx for 2026, indicating a strategic shift toward a more capital-intensive, infrastructure-like operating model.

Analysis

Concentration of hyperscaler business turns Celestica into a demand-levered infrastructure supplier rather than a diversified EMS contractor; that creates higher revenue volatility tied to multi-quarter procurement cycles and increases the likelihood of vendor financing, consigned inventory, or long-term service contracts. Expect working capital swings to widen (DSO/DD/Inventory turns) and margin volatility from uneven absorption of new depreciation and maintenance runs as factory assets come online.

Second-order winners are specialty thermal, power-delivery and advanced PCB suppliers that sell into AI rack builds — these vendors will see order cadence smoothness even if EMS allocations move between contractors. Conversely, smaller EMS peers with limited balance-sheet capacity face a two-fold squeeze: loss of hyperscaler share and the need for external capital or partnership to match bespoke infrastructure investment, which accelerates industry consolidation.

Key risks and catalysts: near-term reversal can come from a single hyperscaler re-routing build strategy or pausing orders (days–weeks to show up in bookings), while execution and contract cadence around the new capital base will be the 6–24 month driver of re-rate. Watch sequential backlog disclosures, customer concentration by end-market, and any move to sale/leaseback or co-invest JV structures — they are binary catalysts that determine whether the market values the company as cyclic EMS or quasi-infra operator.

Key Decisions for Investors

• Long CLS (equity or Jan-2027 LEAP calls, delta ~0.35), size ~2% NAV. Timeframe 12–24 months to capture re-rating if multi-year hyperscaler contracts emerge; set a hard stop at 30% premium loss and take 50% profits on a 100% option gain. Hedge by selling short-dated calls to finance premium if preferred.
• Pair trade: Long CLS / Short FLEX (equal dollar notional) for 6–12 months. Rationale: hedge broad EMS cyclicality while expressing conviction that Celestica’s scale/capacity for AI infra earns a premium. Exit/trim if the spread tightens by 6% absolute or if FLEX announces a large hyperscaler win.
• Long TE Connectivity (TEL) or Amphenol (APH), sized 1–2% NAV, 3–9 month horizon. Trade to capture upside in power/thermal and interconnect suppliers as AI rack build intensity persists; target 20–40% upside vs 10% downside (stop at 12%).
• If uncertain on execution, buy CLS 3-month put protection or establish a collar (long stock + 3–6 month OTM puts) sized to limit downside while keeping upside optionality through 12–24 months. Reduce protection if management secures multi-year committed volumes or forms a capex JV.
