Key Takeaways
- Revenue exceeded all expectations: Q2 2026 revenue reached $4.70 billion, up 62% year-over-year and well above the company's own guidance range of $4.15 billion to $4.45 billion.
- Adjusted EPS (earnings per share) crushed consensus: Adjusted EPS of $2.54 handily beat analyst estimates of approximately $2.29 to $2.31 and surpassed the high end of management's guidance of $2.14 to $2.34.
- Adjusted operating margin hit a new company record of 8.2%, up from 7.4% in the same quarter last year, reflecting strong operating leverage.

- Full-year 2026 guidance was raised significantly: Revenue outlook lifted to $20.5 billion and adjusted EPS outlook raised to $11.30, with management signaling growth acceleration in 2027.
- Stock surged in after-hours trading: Shares rose over 7% in extended trading following the report, adding to a 5.2% gain during the regular session.
Why Celestica's Results Matter Right Now
Celestica's Q2 2026 earnings, released after the close on July 27, came at an important juncture for the electronics manufacturing services sector. As a key supplier of data center infrastructure, the company stands to benefit from ongoing AI-related capital spending. Shares had already declined about 36% from the 52-week high of $474.02 ahead of the report, so investors were particularly focused on whether demand momentum could hold. The CCS segment, driven by hyperscale cloud providers building out AI capacity, was the main area to watch. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry. This quarter served as a useful test of Celestica's ability to scale revenue profitably while navigating supply chain issues.
What the Numbers Showed
The results came in well ahead of expectations across the board. Revenue reached $4.70 billion, a 62% increase from $2.89 billion in Q2 2025. That figure cleared both the consensus range of roughly $4.38 billion to $4.39 billion and the top end of the company's own guidance. On the bottom line, GAAP diluted EPS was $3.17 versus $1.82 a year earlier. Adjusted EPS of $2.54 exceeded analyst estimates of about $2.29 to $2.31 and management's range of $2.14 to $2.34. Net earnings totaled $368.8 million.
Margins also improved. GAAP operating margin rose to 9.8% from 9.4%, while adjusted operating margin reached a record 8.2%, up from 7.4%. The CCS segment remained the standout, with revenue climbing 84% to $3.81 billion and segment margin expanding to 8.7% from 8.3%. Hardware Platform Solutions revenue within CCS grew 58% to around $1.9 billion. The ATS segment grew a steadier 8% to $0.89 billion, with margin improving to 6.3% from 5.3%.
How the Market Reacted
Investors responded positively. Shares finished the regular session at $321.06, up 5.2%, then rose another 7.2% in after-hours trading to around $344. The move reflected both the size of the beat and the upward revision to full-year guidance. Sentiment had been measured before the print, partly due to the prior pullback and concerns around component availability. Management pointed to stronger second-half forecasts and better component supply as reasons for the raised outlook. The after-hours reaction suggested many viewed the results as confirmation of Celestica's position in the AI buildout.
Looking Ahead and What to Watch
Guidance for the rest of the year points to continued momentum. For Q3, Celestica expects revenue of $5.25 billion to $5.55 billion and adjusted EPS of $2.88 to $3.08. Full-year revenue guidance moved to $20.5 billion from $19.0 billion, with adjusted EPS lifted to $11.30 from $10.15. Free cash flow guidance increased to $600 million from $500 million, and the adjusted operating margin target rose to 8.4%.
CEO Rob Mionis noted that revenue growth should accelerate beyond the 65% rate expected for 2026, supported by robust demand and new programs. Adjusted EPS is projected to grow even faster than revenue in 2027, helped by margin expansion. Key areas to monitor include customer concentration in the CCS business, supply chain conditions for custom silicon and memory, and free cash flow discipline amid higher capital spending. The combination of a strong backlog, improving margins, and higher growth expectations leaves Celestica well positioned in the current environment.
