The artificial intelligence frenzy often brings to mind chip giants like Nvidia or tech behemoths such as Microsoft and Google. But real AI infrastructure goes far beyond chips alone – servers, switches, storage, cooling, and power, every link requires substantial hardware support. For Canadian investors, one homegrown stock is quietly positioning itself at the forefront of this modern day gold rush: Celestica (TSX:CLS).
Not a Landlord, but the Construction Crew
Celestica is not a data-centre landlord that collects rent from server farms. Instead, it is a Toronto based electronics manufacturing services provider, offering end-to-end hardware solutions from design and manufacturing to supply-chain management. Its business spans AI, cloud computing, hybrid cloud, networking, storage, aerospace, defence, healthcare technology, and industrial equipment. In simple terms, when cloud providers need faster data-centre networks, AI workloads require custom systems, or massive amounts of data demand low-latency transmission, Celestica is the company that turns blueprints into physical hardware.
Explosive Earnings, Raised Guidance
The latest quarterly results were hard to ignore. In the first quarter of 2026, Celestica reported revenue of US$4.05 billion, up 53% year over year. Adjusted earnings per share reached US$2.16, while adjusted operating margin hit 8.0%. Management also raised its full-year outlook, now expecting 2026 revenue of US$19.0 billion and adjusted EPS of US$10.15.
The core growth driver was the Connectivity and Cloud Solutions segment, which saw revenue jump 76% year over year. That segment includes communications equipment, servers, and storage – precisely the intersection where AI and cloud demand meet physical hardware.
Next-Generation Networking Equipment on the Horizon
A notable catalyst is Celestica’s announcement of a co-packaged optics Ethernet switch programme with a hyperscaler customer. The product targets AI scale-out networks, using 1.6 terabit switch silicon, optical interconnects, and liquid cooling technology, with production expected to ramp in 2027. This is not a vague AI promise; it points to the kind of next-generation networking gear that data centres will need as AI models continue to grow larger and more expensive to run.
Risks Remain, Volatility Likely
Of course, Celestica is not without risks. The stock already reflects a great deal of optimism. Rapid growth creates high expectations, and high expectations leave little room for error. If AI spending slows, if large customers delay orders, or if margins slip, the stock could pull back sharply. Moreover, the business depends heavily on a handful of major customers and programmes.
The Bottom Line
Data centres may be the new gold rush, but not every investor needs to buy a chipmaker or a power utility. Some of the strongest winners could come from the companies building the equipment behind the scenes. For patient investors who can handle volatility, Celestica looks like one TSX stock worth considering before the AI infrastructure trade becomes even more crowded.
