Hidden Manufacturing Stock Soars 15% in AI Data Center Rally

On the previous trading day on the New York Stock Exchange, Celestica Inc. (CLS) closed at $441.44, up 15.34% in a single session. Trading volume topped 1.72 million shares, and the company’s market capitalization climbed to about $50.7 billion, adding roughly $9.2 billion in value in just one day.

In its first-quarter results, Celestica reported revenue of $4.05 billion, a year-over-year increase of more than 50% that exceeded its own guidance. Citing strong demand for AI and cloud infrastructure, management raised its full-year 2026 revenue outlook to $19 billion, further boosting investor confidence.

High-value offerings—such as switching platforms for AI data centers and servers for hyperscale customers—now account for a growing share of Celestica’s portfolio, earning it a reputation as a core “AI infrastructure supply-chain” stock. North American brokerages have issued strong-buy ratings and highlighted additional upside potential.

Headquartered in Toronto, Canada, Celestica is an electronics manufacturing services provider that designs and produces infrastructure hardware—including advanced communications equipment, cloud servers, and AI and semiconductor systems—for hyperscalers and network-equipment companies. Its operations are organized into two segments: Advanced Technology Solutions and Cloud & Connectivity Solutions. Amid the current AI data-center investment cycle, Celestica has emerged as one of the largest beneficiaries, prompting a revaluation of its stock.
