Celestica’s Q2 2026: Revenue Rockets to $4.70B, EPS Leaps, Guidance Gets a Lift

What Celestica reported

In the quarter ended June 30, 2026, Celestica generated $4.70 billion in revenue, up 62% from $2.89 billion in Q2 2025. GAAP earnings from operations were 9.8% of revenue, a modest improvement from 9.4% a year earlier. On the non-GAAP side, adjusted operating margin stood at 8.2%, up from 7.4% in Q2 2025.

Earnings per share followed the same upward arc: GAAP EPS reached $3.17, versus $1.82 in Q2 2025. Adjusted (non-GAAP) EPS came in at $2.54, up from $1.39 in the year-ago period. The beat on both revenue and EPS rests on the company’s stated capacity to push margins higher even as it scales revenue meaningfully.

Celestica also underscored that these results “exceed the high end” of its prior guidance, a phrasing that invites readers to consider whether an external earnings surprise is lurking or if this is simply a well-executed upgrade of expectations. The company also reaffirmed that per-share figures are based on diluted shares outstanding, and noted that the figures incorporate ongoing non-GAAP adjustments.

Two operating segments and what that means for the margin story

The company segments its business into Connectivity & Cloud Solutions (CCS) and Advanced Technology Solutions (ATS). The press release positions both segments as drivers of the revenue surge, with overall performance evaluated by segment revenue, segment income, and segment margin. For investors, the mix implies that growth isn’t just volume-driven; margin discipline across CCS and ATS remains a focal point as demand for data-center-related services and embedded technology expands.

Guidance lifted: a 2026 revenue forecast and EPS target that traders can anchor to

Celestica raised its 2026 outlook to approximately $20.5 billion in revenue and an adjusted EPS of about $11.30. Those targets translate into year-over-year increases of roughly 65% in revenue and an even larger percentage rise in EPS, reflecting a mix of top-line momentum and margin expansion. The leadership framed the upgrade as a reflection of stronger first-half performance, improved second-half forecasts from customers, and better component supply—factors that can support further upside if demand remains resilient.

Looking beyond 2026, Celestica signaled that revenue growth in 2027 is expected to accelerate beyond the roughly 65% pace projected for 2026, with adjusted EPS growing faster than revenue thanks to higher expected operating margins. In other words, the company sees a leverage-friendly path as it scales its programs and wins new programs into the next year and beyond.

Notes to investors include the typical caveats around Use of Non-GAAP Measures and a Schedule 1 reconciliation. The company also reminded readers that per-share information assumes diluted shares outstanding unless otherwise noted.

What this could portend for Celestica and peers

From a reader’s chair, the printout looks constructive: a large, broadened revenue base with margin uplift and an explicit path to higher profitability in 2027. The 62% YoY revenue gain hinges on a robust mix of CCS and ATS programs—perhaps a sign that Celestica’s data-center and aerospace/industrial portfolios are not only resilient but benefiting from multi-year secular demand cycles in cloud infrastructure, connectivity, and advanced equipment.

Margins are moving in the right direction, bolstered by scale and operational efficiency. The jump in GAAP operating margin to 9.8% plus a non-GAAP margin of 8.2% suggests the operating engine is gaining traction, not merely riding a short-term push from revenue growth.

For peers, the takeaway may be: if you can deliver double-digit top-line growth while expanding margins through a disciplined mix shift and supply resilience, equity markets will reward you with multiple compressions in the right direction. But the caveat remains meaningful: many investors will ask how much of this is demand-driven versus share gains from efficiency and program wins. The absence (so far) of a disclosed consensus estimate for EPS or revenue means the stock will be judged against its own guided targets—and against how well the market believes those targets are achievable in a still-choppy supply environment.

Risks and considerations for sector peers

Non-GAAP adjustments keep the headline numbers clean, but the underlying economics require scrutiny: contract mix, program phasing, and component availability will continue to shape quarterly results. The two-segment structure means different end-markets could move in different directions; a slowdown in one segment could be offset by strength in another, but only if the company sustains its operating-leveraged growth. For sector peers, the message is clear: maintain focus on gross margin retention as revenue scales, guard against input-cost volatility, and keep an eye on how quickly customers convert demand into realized utilization.

Bottom line

Celestica’s Q2 2026 narrative blends outsized revenue growth with meaningful margin expansion and a raised 2026 revenue forecast plus higher EPS targets. The tone from management is confident about the second half and the trajectory into 2027. For investors, CLS offers a case study in how a diversified contract manufacturer can translate robust demand into a higher-quality earnings story, provided it can sustain its operational rhythm and keep non-GAAP metrics aligned with GAAP realities. The real test will be whether consensus across the Street aligns with the company’s own refreshed outlook, and whether the trend persists as supply chains normalize and customers finalize second-half orders.
