Celestica (NYSE: CLS; TSX: CLS) has transformed from a traditional electronics manufacturing services (EMS) provider into a diversified leader in design, manufacturing, and supply chain solutions for advanced technology markets. The company’s two primary segments—Advanced Technology Solutions (ATS) and Connectivity & Cloud Solutions (CCS)—now serve a global roster of clients in aerospace, defense, industrial, healthtech, capital equipment, and, crucially, the data center and communications infrastructure markets.
The most recent quarterly results underscore the strength of Celestica’s execution. In Q1 2025, Celestica posted revenue of $2.65 billion, a 20% year-over-year increase that exceeded consensus estimates and the upper end of management’s own guidance. Adjusted EPS surged to $1.20, up 45% from the prior year. The CCS segment was the standout, with revenue up 28% year-over-year to $1.84 billion, driven by an 87% jump in the Communications sub-segment as hyperscaler customers accelerated deployments of 400G and 800G switches and networking gear.
Celestica’s raised full-year 2025 outlook is a testament to management’s confidence in the sustainability of these trends. The company now expects revenue of $10.85 billion (up from $10.7 billion previously) and adjusted EPS of $5.00, reflecting robust demand visibility, especially in CCS and AI-related infrastructure.
New product launches, such as the ES1500 enterprise access switch and the DS4100 top-of-rack switch, position Celestica at the forefront of supporting high-density, high-bandwidth IT and IoT deployments. The ramp-up of 800G switch programs with hyperscaler customers and the anticipated reacceleration of the Enterprise sub-segment in the second half of 2025 further reinforce the company’s growth prospects.
Financially, Celestica’s profile is robust, though not without areas for scrutiny. The company’s EBIT margin stands at 5.8%, and net income in Q1 2025 was $86.2 million, reflecting resilience in the face of market fluctuations. Liquidity ratios—quick ratio at 0.8 and current ratio at 1.4—are adequate, though not exceptional.
Celestica’s competitive positioning is anchored by its deep relationships with leading hyperscalers, a track record of innovation, and a global manufacturing and supply chain footprint. The company’s focus on AI/ML compute, networking, and storage solutions for data centers aligns it with the most powerful secular trends in technology. Peer comparisons reinforce Celestica’s standing: with a market cap of $17.6 billion and trailing revenue of $10.1 billion, the company’s scale is matched by few direct competitors.
However, the very success that has powered Celestica’s stock price also introduces valuation risk. The company now trades at a trailing P/E of 41.67 and a forward P/E of 28.71—multiples that are elevated relative to historical norms and many peers, especially for a business with mid-single-digit net margins. The price-to-sales ratio of 1.75 and price-to-book of 11.31 further underscore the premium investors are paying for growth.
While the analyst consensus target remains above the current share price, the gap has narrowed, and some market observers have drawn parallels to the excesses of the Dot-com era, cautioning that any disappointment in execution or a slowdown in AI infrastructure spending could trigger a sharp correction.
In conclusion, Celestica stands at the intersection of powerful secular trends and has demonstrated impressive operational and financial momentum. Its exposure to AI infrastructure, hyperscaler networking, and next-generation compute positions it for continued growth, and management’s execution has thus far been exemplary. However, the stock’s valuation now reflects a great deal of optimism, and the risk/reward balance is less compelling than it was in prior years.
For sophisticated investors, Celestica remains a high-quality, high-beta play on the AI and cloud infrastructure boom. The shares are attractive for those with a strong conviction in the durability of these trends and a tolerance for volatility, but caution is warranted at current levels.
