Celestica Up 220% in 2025, Debuts AI Storage and 1.6TbE Switches Ahead of Q4

CLSCLS

Celestica shares have rallied 220% in 2025 and appear to be forming a base ahead of its Q4 earnings report. The data center specialist has launched AI-focused storage solutions and 1.6TbE switches but continues to face weakness in its ATS segment despite expectations of strong demand in 2026.

1. Strong 2025 Performance and Base Formation

CLS shares surged 220% over the course of 2025, driven by robust demand for its data center infrastructure solutions. After peaking in early December, the stock has since formed a base between technical support levels that analysts view as a healthy consolidation. Management cites improving order visibility for 2026 and a growing pipeline of customer commitments, particularly in hyperscale and enterprise colocation facilities, as key factors underpinning confidence in sustained revenue growth next year.

2. Product Launches and Growth Drivers

In the past quarter, CLS rolled out its AI-optimized storage array and a line of 1.6TbE network switches designed to meet the low-latency requirements of machine learning workloads. The new storage solution features NVMe-over-Fabric connectivity and modular expansion bays that can scale to petabyte capacity, while the switches include advanced telemetry and deep packet inspection. Early adopter feedback from a leading cloud provider indicates a 30% reduction in data-pipeline bottlenecks, suggesting material upside to CLS’s high-margin services segment.

3. ATS Weakness and Valuation Concerns

Despite product momentum, the company’s application-to-storage (ATS) integration segment has shown sequential revenue declines due to supply-chain disruptions affecting custom backplane components. That weakness has forced management to revise its Q4 guidance lower for ATS bookings by approximately 10%. Meanwhile, CLS is trading at a double-digit premium to peer group multiples based on forward EBITDA forecasts, raising questions about near-term downside if execution falters or broader data center spend moderates.
