Why Smart Money Is Secretly Loading Up on This Hidden Gem

Celestica has attracted significant institutional interest—$6.32 billion in inflows versus $4.28 billion in outflows over the past 12 months, with large funds increasing stakes in Q3 2025—after reporting Q3 revenue up 28% y/y to $3.19 billion and adjusted EPS up 52% to $1.58 and raising FY2025 guidance to $12.2 billion revenue and $5.90 adjusted EPS while targeting $16 billion in 2026 (31% y/y). The company, which holds north of a 50% share in the Ethernet switch market, is benefitting from hyperscaler upgrades (400G→800G and future 1.6T cycles), strong demand for ASIC-based AI compute systems and a major hyperscaler's custom compute ramp, giving it 12–15 months of revenue visibility. Management also plans mass production of a rack‑scale custom AI system in 2027 that could add multiple billions in revenue, positioning Celestica as a meaningful AI-infrastructure exposure for investors.

Analysis

Institutional interest in Celestica has increased with $6.32 billion in inflows versus $4.28 billion in outflows over the last 12 months, and several large funds materially increased stakes in Q3 2025. The company reported Q3 2025 revenue of $3.19 billion, up 28% year‑over‑year, and adjusted EPS of $1.58, up 52% y/y, prompting management to raise FY2025 revenue guidance from $11.55 billion to $12.2 billion and adjusted EPS guidance from $5.50 to $5.90.

Celestica holds over a 50% share of the Ethernet switch market and is benefiting from hyperscaler transitions from 400G to 800G and an anticipated 1.6T upgrade cycle, which supports demand for its ASIC-based AI compute systems and rack-scale offerings. Management cites 12–15 months of confirmed demand visibility, a major hyperscaler ramp for custom compute, and a 2026 revenue target of $16 billion (31% y/y on guided 2025), implying strong multiyear top-line momentum.

Near-term strength and raised guidance support a constructive revenue and margin trajectory, but the material upside tied to mass production of a rack-scale AI system in 2027—described as potentially “multiple billions” of revenue—is execution dependent and concentrated among hyperscaler customers. Key risks to monitor are backlog conversion, timing of hyperscaler ramps and sustained adjusted EPS improvement; sentiment is strongly positive (0.78) and market impact is moderate (0.6), so re-rating risk exists if execution slips.

Key Decisions for Investors

• Consider initiating or modestly increasing exposure to Celestica to gain AI-infrastructure exposure after a 28% y/y revenue beat, 52% EPS growth, and upwardly revised FY2025 guidance, but limit position size because 2027 upside is contingent on successful mass production and concentrated hyperscaler adoption
• Monitor quarterly order backlog, the disclosed 12–15 month demand visibility metric, and public confirmations of hyperscaler ramp timing as primary catalysts to add to positions
• Require evidence of sustained adjusted EPS traction and conversion of FY2025 guidance into 2026 revenue momentum before moving to a full overweight allocation
• Use staged purchases or protective hedges to manage event risk around product ramp timing and customer concentration, and consider trimming on outsized short-term share-price appreciation tied to sentiment
