Key Takeaways
CLS delivered Q4 earnings and revenue beats, driven by 64% year-over-year growth in the CCS segment.
CLS saw strong demand for 400G and 800G switches and AI/ML compute programs, driving the top line.
CLS generated strong free cash flow, but faces ATS weakness and customer concentration risk.
Celestica, Inc. (CLS - Free Report) recorded strong fourth-quarter 2025 results with adjusted earnings and revenues beating the respective Zacks Consensus Estimate. Top-line expansion year over year is backed by strong growth in the Connectivity & Cloud Solutions (CCS) segment. Management’s emphasis on innovation, product diversification and AI advancements was a key growth driver.
CLS Rides on Strength in CCS Segment and Robust Liquidity
Celestica is benefiting from healthy traction in the CCS segment, backed by robust demand in the Communication and Enterprise businesses. Resilient demand for 400G switches and 800G network switch adoption is driving growth in the Communications end market. Ramping of a next-generation AI/ML compute program with a large hyperscaler customer is driving growth in the Enterprise business. Revenues from the Enterprise business were up by 33% year over year, while the communications end market generated 79% year over year growth in net sales. Total revenues in the Connectivity & Cloud Solutions (CCS) segment improved 64% year over year to $2.86 billion.
The company is closely working with Google on the development of complex data center hardware and systems. It is the preferred manufacturing partner for Google’s Tensor Processing Unit (TPU). The company is steadily expanding its capacity and capabilities in the United States and globally to support growing adoption of Google’s custom silicon TPU systems.
In the fourth quarter of 2025, Celestica generated $250.6 million in cash from operations compared with $143.4 million in the year-ago quarter. Free cash flow was $155.9 million, up 62.7% year over year. This accentuates efficient capital management and implies that the company is well-positioned to invest in growth initiatives, as well as pay debt and dividends.
The company’s inventory balance was $2.19 billion, up $427 million compared to the prior year. Cash cycle days were 61 days; an improvement of 8 days compared to the prior year quarter. A cash cycle indicates the average time it takes to convert inventory goods into cash through sales. Celestica’s reduced cash cycle days are a positive factor. Moreover, CLS’ strong liquidity better positions it to navigate economic downturns and capitalize on emerging growth opportunities in the electronics manufacturing service industry.
Major Challenges for CLS
Celestica’s growth is highly dependent on AI data center spending by hyperscalers. Any downtrend in hyperscaler capex can significantly impact demand for Celestica’s data center solutions. Moreover, the company is highly exposed to significant customer concentration risk. Its largest three customers generated approximately 63% of total revenues in the fourth quarter of 2025. The company operates in a highly competitive electronics manufacturing services industry. It faces competition from other industry leaders such as Jabil, Inc. (JBL - Free Report) , Sanmina and Flex Ltd. (FLEX - Free Report) . Given the competitive nature of the industry, any changes in the demand pattern of any of the major customers can have a significant negative impact on the company’s financial results.
It is also witnessing weakness in the Advanced Technology Solutions segment. Revenues declined 1% year over year in the fourth quarter. Capital Equipment business remains soft. The Aerospace and Defense portfolio reshaping strategy is weighing on growth in this segment.
Moreover, the company generates the lion’s share of its revenues outside of North America. This exposes it to foreign exchange fluctuations. Growing geopolitical volatility worldwide can impact the company’s operations.
Price Performance
Celestica has increased 125.4% in the past year compared with the Electronics - Manufacturing Services industry’s growth of 74.4%. The stock has outperformed the Zacks Computer & Technology sector and the S&P 500 during the same time frame.

Key Valuation Metric of CLS

End Note
Celestica is witnessing solid momentum in the CCS segment, backed by solid demand for the company’s enterprise-level data communications and information processing infrastructure products, such as routers, switches, and data center interconnects. Strong growth in cash flow and robust liquidity are positive factors. Capital discipline and efficient capital management are tailwinds.
However, demand softness in the ATS segment due to softness in the capital equipment business is weighing on the top line. Customer concentration and high dependence on hyperscalers’ AI-related spending remain a major concern. With a Zacks Rank #3 (Hold), CLS appears to be treading in the middle of the road, and new investors could be better off if they trade with caution.
