It’s rare to see a TSX-listed stock soar nearly 400% in a single year and still look like it has more room to climb. Yet that’s exactly what Celestica (TSX:CLS) has done. Once an under-the-radar name, the company has become one of the most talked-about Canadian stocks of 2025, fueled by the artificial intelligence (AI) boom and its growing leadership in high-performance computing and advanced manufacturing.

Celestica’s rapid rise isn’t just about catching an AI wave—it’s the result of a disciplined strategy, long-term contracts with major data centre players, and an expanding customer base across multiple industries, including aerospace, healthcare, and communications. The company’s consistent execution and strong fundamentals suggest this rally could be more than just a short-term surge.
A Top TSX Performer With Momentum
Trading at $472.09 per share with a market cap of $54.3 billion, Celestica has climbed roughly 384% over the past year and an astonishing 3,000% in three years, cementing its place among the strongest TSX performers in recent history.
Much of this momentum has come from its Connectivity and Cloud Solutions (CCS) segment, which posted 43% year-over-year growth in Q3 2025. Within that, the company’s AI-focused hardware platform solutions jumped 79% year over year, reflecting robust demand from hyperscale data centre clients building out AI infrastructure.

Beating Expectations, Quarter After Quarter
Celestica has developed a track record of outperforming its own guidance. In Q3, revenue surged 28% year over year to US$3.2 billion, exceeding projections, while adjusted earnings rose 52% to US$1.58 per share, also ahead of expectations.
Encouraged by this momentum, management raised its full-year 2025 outlook, now targeting US$12.2 billion in revenue and US$5.90 per share in adjusted earnings. Looking ahead, Celestica issued a bullish 2026 forecast, expecting US$16 billion in revenue and US$8.20 per share in adjusted earnings — a strong signal that its growth story is far from over.
Why the Winning Streak Could Continue
Beyond AI, Celestica is expanding its footprint in aerospace, industrial, and healthcare technology, driven by its Advanced Technology Solutions (ATS) segment. Even though ATS revenue dipped slightly last quarter, profit margins improved thanks to tighter cost management.
The company is also investing heavily in capacity expansion, innovation, and strategic partnerships with global cloud and computing leaders. As these partners ramp up AI and high-performance data centre spending, Celestica is well positioned to benefit from a sustained demand cycle.
While many growth stocks flash and fade, Celestica’s combination of strong earnings growth, diversified exposure, and a disciplined execution strategy makes it a rare winner built for the long haul. Even after its incredible run, this TSX powerhouse still looks like it has plenty of upside ahead.
