Celestica Inc. (NYSE: CLS) (TSX: CLS) – Q1 2026 Earnings
Celestica Inc. (NYSE: CLS) (TSX: CLS) – Q1 2026 Earnings
Press release and earnings call link
Section 1: Short Tear Sheeet
Celestica is a global design, manufacturing, and supply-chain partner for complex electronics, increasingly focused on AI data-center infrastructure. Its main growth engine is CCS (Connectivity & Cloud Solutions), which serves hyperscaler cloud customers through networking switches, storage, and AI/ML (artificial intelligence / machine learning) compute programs. Its second segment, ATS (Advanced Technology Solutions), serves aerospace & defense, industrial, healthtech, and capital equipment markets. The company is no longer just a lower-margin electronics manufacturing services provider; the call suggests it is moving up the value chain into HPS (Hardware Platform Solutions), meaning Celestica is helping design and manufacture more complex systems, not just assemble them. The financial trajectory is very strong: Q1 revenue grew 53%, adjusted EPS grew 80%, and management raised 2026 revenue guidance from $17 billion to $19 billion while also saying 2027 visibility has improved.
Quarterly Results
Earnings Release Date: Apr. 27, 2026
Stock Price: $273.38
Market Cap: $31438.7 million
Q1 2026 sales of $4,047.0 million vs $2,648.6 million in the prior year
Q1 2026 Non-GAAP Adjusted EPS of $2.16 vs $1.20 in the prior year
Q1 2026 GAAP Diluted EPS of $1.83 vs $0.74 in the prior year
Quick Takeaway
Celestica is in a high-growth AI infrastructure expansion phase, driven by hyperscaler demand, 800G and 1.6T networking ramps, AI/ML compute, CPO, HPS design programs, and future rack-scale AI opportunities. The company’s tone was highly confident, supported by raised 2026 guidance, strong 2027 visibility, and record backlog/pipeline commentary. The main risks are customer concentration, supply constraints, rising inventory, and elevated capex. Execution on component supply, capacity expansion, and hyperscaler program ramps will be critical.
Press Release vs Call Transcript Comparison
Celestica’s Q1 results were not just “good” in the abstract. Revenue growth of 53% and adjusted EPS growth of 80% are exceptional for a hardware manufacturing and design partner, especially with adjusted operating margin reaching 8.0%, which management called a new high. The quality of the beat also matters: the company exceeded EPS guidance despite some AI/ML compute revenue timing being held back by components, suggesting mix and productivity were strong enough to offset some shipment friction.
The more important story is the migration from manufacturing capacity to engineering-led platform participation. HPS revenue of $1.7B, up 63%, is not just another segment datapoint; the call ties HPS to 400G, 800G, 1.6T, CPO, AMD Helios, and digital-native rack-scale systems. That implies Celestica is being pulled into the architecture layer of AI infrastructure, where customer relationships may be stickier and margins may be better than legacy contract manufacturing.
The bear case is not demand. The call repeatedly suggests demand is strong, durable, and cumulative. The real risks are customer concentration, supply chain bottlenecks, high capital requirements, and the possibility that hyperscaler roadmaps shift. Investors should view the company as a direct AI infrastructure beneficiary, but not one with software-like margins or low capital intensity.
Investor Underappreciation Signals
✅CPO Is More Than a Switch Win — The press release announces the CPO program, but the call explains that it validates Celestica’s move into advanced co-design for next-generation hyperscaler networking, which investors may miss if they treat it as a normal manufacturing award.
✅2027 Revenue May Already Be De-Risking — Management’s call commentary implies a 2027 revenue floor around $25.5B with upside from already-won programs, which may not be fully appreciated because the press release only says 2027 visibility has strengthened.
✅Supply Constraints Are Masking Demand — The call clarifies that the AI/ML compute shortfall was caused by component supply, not weak customer demand, which could lead investors to underestimate future catch-up revenue.
✅HPS Is Becoming the Real Growth Engine — HPS revenue was disclosed in the release, but the call ties HPS to nearly every major future AI infrastructure program, suggesting Celestica’s design content may be expanding faster than the headline numbers imply.
✅ATS Recovery Adds a Second Layer to the Story — Investors may view Celestica as purely a hyperscaler AI story, but the call points to ATS returning to growth with better margins, giving the company an additional earnings support if capital equipment demand improves.
✅Long Lead Times Are Creating Contractual Visibility — The call says long custom-silicon lead times are pushing planning into 2028 and include NCNR protections, which may make future revenue less speculative than typical electronics manufacturing cycles.
✅Capex Is High, But Tied to Won Programs — The call’s $1.5B rough 2027 capex placeholder sounds like a cash-flow risk, but management said spending is tied to program-specific business cases with strong returns, which may soften concerns about overbuilding.

Positive Insights
Negative Insights
Tariff Risk
Tariffs were not discussed in detail during the call. Management did not quantify tariff exposure, revenue impact, margin impact, or any direct mitigation plan tied specifically to U.S. tariffs or trade policy.
There were indirect references to geographic capacity planning, including capacity investments in Southeast Asia, specifically Thailand, and in the U.S., specifically Texas. These investments appear primarily tied to growth, customer alignment, and supply-chain capacity rather than explicitly to tariff mitigation.
Tariff risk takeaway: Based only on the transcript, tariffs were not presented as a material near-term issue. Investors should still verify tariff exposure in the 10-Q/10-K because Celestica operates in global supply chains and serves hyperscaler hardware programs that may involve cross-border components, manufacturing, and customer logistics.
Hot Stock Trends Analysis
Previous Earnings Call
Quarter-over-quarter comparison (Previous Analysis)
In Q4 2025, Celestica framed itself as a company entering a major AI infrastructure expansion phase after a record year, with management emphasizing hyperscaler demand, Google TPU work, 800G networking, and a large capex step-up to support booked programs. The tone was confident but still preparatory, focused on building capacity and proving that 2026 and 2027 growth would be backed by customer commitments.In Q1 2026, the story shifted from preparation to acceleration, as Celestica beat expectations, raised 2026 guidance again, and gave stronger signals that 2027 revenue could step meaningfully higher. Management’s messaging became more specific and strategic, highlighting CPO, 1.6T, Helios, digital-native rack-scale systems, and deeper co-design work as evidence that Celestica is moving up the AI infrastructure value chain.
Year-over-year comparison
In Q1 2025, Celestica was proving that its AI infrastructure exposure was real, but the story was still partly about managing uncertainty. Management raised guidance modestly, emphasized hyperscaler networking demand, and was still waiting for AI/ML compute to reaccelerate after a technology transition.
By Q1 2026, the story had shifted from validation to rapid scaling, with revenue, EPS, margins, backlog, and 2027 visibility all moving sharply higher. The upside expanded through 1.6T, CPO, Helios, rack-scale AI systems, and HPS design work, while the main risk shifted from tariffs to execution, component supply, capacity expansion, and working capital.
