Celestica (NYSE:CLS) is one of the most direct ways for a long-horizon portfolio to gain exposure to the AI infrastructure buildout right now. The company designs and manufactures electronics and hardware for major technology customers, earning revenue by building products such as servers, networking equipment, and data-center systems.
The company is compounding revenue north of 50% with expanding margins, management has raised full-year guidance twice in six months, and the stock trades at a forward multiple below its growth rate. This is a pick-and-shovel play with visible 2027 program wins already booked.
Q1 FY26 revenue hit $4.05 billion, up 52.8% year over year, with adjusted EPS of $2.16 beating the $2.08 consensus. That was the fifth straight EPS beat. Adjusted operating margin printed 8.0%, a company record, and the Connectivity & Cloud Solutions segment grew 76% year over year to $3.24 billion. Management raised FY26 guidance to $19.0 billion in revenue and $10.15 in adjusted EPS, up from $17.0 billion and $8.75 just one quarter earlier.
At $335.50, CLS trades at a forward P/E of 30 against quarterly earnings growth of 147.3% year over year. The Street consensus target sits at $448, with 20 of 21 analysts rating it Buy or Strong Buy and zero Sells. The stock is still trading roughly 30% below its 52-week high of $474.02, giving new buyers a discount to a name that returned 113.82% over the past year.
Flex (NASDAQ:FLEX) and Jabil (NYSE:JBL) are the obvious EMS (Electronics Manufacturing Services) alternatives, and neither is keeping up. Flex grew FY26 revenue just 8.14% to $27.9 billion with an adjusted operating margin of 6.5% in its most recent quarter. Jabil's Q3 FY26 revenue rose 11.8% year over year against a full-year core operating margin guide of 5.8%.
Celestica is growing more than four times faster than Flex and posting a stronger margin profile roughly 200 basis points above Jabil's.
Customer concentration is one of the standard talking points among bears. Three customers were 36%, 15%, and 12% of Q4 FY25 revenue, meaning they cumulatively accounted for 63% of revenue.
Those customers are hyperscalers with published capex trajectories, and CLS just won a Co-packaged Optics Ethernet switch program using 1.6 Terabit silicon that begins ramping in 2027, alongside expanded U.S. manufacturing capacity for Google TPU systems. While customer concentration introduces risk, it also provides a tailwind when the customer list includes the largest AI spenders on earth.
Long-term investors seeking direct AI infrastructure exposure at a reasonable multiple might consider putting Celestica at the top of their research list today. Celestica is scheduled to release Q2 earnings after the market closes on July 27.
