Celestica Surges 139% in 6 Months: How to Play the Stock

Celestica (CLS) shares have surged 139% over the past six months, significantly outperforming its industry and peers, driven by robust demand in its Connectivity & Cloud Solutions segment, particularly for 800G switches and AI-related data center products. This growth is supported by strategic collaborations with tech giants like Broadcom and AMD, strong capital discipline with growth-focused capital expenditure, and a resilient global supply chain. The company is also proactively increasing inventory to meet anticipated strong demand, and its earnings estimates for 2025 and 2026 have been revised upwards, positioning CLS as a strong investment option despite trading at a valuation premium.

Analysis

Celestica, Inc. (CLS) has demonstrated significant market outperformance, with its stock surging 139% in the last six months, substantially exceeding the 64.9% growth of its industry and the gains of peers Jabil (45.1%) and Sanmina (54.2%). This momentum is primarily fueled by robust demand within its Connectivity & Cloud Solutions (CCS) segment, driven by the secular trend of AI adoption and the corresponding data center build-out. Specifically, the transition from 400G to 800G switches and strong demand for related hardware are key growth vectors. The company's strategic collaborations with technology leaders like Broadcom, for an 800G top-of-rack switch, and AMD, for a next-generation storage controller, solidify its competitive position. Operationally, Celestica exhibits strong financial discipline, with capital expenditure at 1.1% of revenue—below its target range—and focused on growth initiatives. A notable indicator of anticipated future demand is the aggressive inventory ramp-up to $1.92 billion in the second quarter, which is supported by an efficient cash cycle that decreased to 66 days, suggesting effective working capital management. Furthermore, upward revisions to 2025 and 2026 earnings estimates underscore a positive fundamental outlook, though the stock currently trades at a premium forward P/E of 33.33 versus the industry's 21.56.

Key Decisions for Investors

• Given the powerful tailwinds from AI infrastructure spending and positive earnings estimate revisions, investors may view Celestica as a key holding to gain exposure to the data center hardware cycle, despite its significant recent appreciation.
• The premium valuation, reflected in a forward P/E of 33.33, implies high growth expectations are already priced in, suggesting investors should monitor for any signs of slowing demand or execution missteps that could trigger a correction.
• Closely watch future earnings reports for the conversion of the $1.92 billion inventory into revenue and the maintenance of a stable or improving cash cycle, as these are critical indicators that the company's demand forecasting is accurate.
• Consider the stock's outperformance relative to peers like Jabil and Sanmina as a sign of superior execution, but remain vigilant for any shifts in the competitive landscape or supply chain dynamics that could alter this positioning.
