Booming AI infrastructure demand is a tailwind for Celestica
Celestica's revenue soared by 28% year over year in the third quarter, easily beating analyst expectations. Adjusted earnings per share also exceeded analyst estimates, growing by 52% to $1.58.
On top of reporting strong results, Celestica boosted its full-year outlook and provided a solid outlook for 2026. For 2025, revenue is now expected to be around $12.2 billion, with adjusted EPS of $5.90. For 2026, revenue should rise to $16 billion, and adjusted EPS should reach $8.20.
In an interview following the earnings report with CNBC, Celestica CEO Robert Mionis described its role in the artificial intelligence (AI) infrastructure market as "laying the tracks ahead of the freight train." The company designs storage, compute, and networking solutions for cloud data centers, and booming demand for AI infrastructure is helping to push up revenue.
The company's 2026 outlook is supported by strong demand from its largest customers. Celestica also noted that there were "indications of these dynamics continuing into 2027." Revenue will grow by 31% in 2026 if the company hits its guidance, and equally impressive growth could follow in 2027 if demand for AI infrastructure holds up.

Is Celestica a buy?
Things are going great for Celestica right now, but the stock's valuation has become stretched. Based on that 2026 outlook, Celestica stock trades for roughly 42 times forward earnings. There's not a lot of room for error going forward.
By hitching its wagon to the AI infrastructure boom, Celestica is exposed to the risk of the boom turning into a bust. While all signs point to growing demand for AI infrastructure for now, Celestica's fortunes could shift quickly down the road.
