Celestica Raises 2026 Revenue Outlook to $21.0 Billion, Sets Initial 2027 Target of $40 Billion on AI Infrastructure Demand

Celestica Inc. (NYSE: CLS) raised its 2026 revenue outlook to $21.0 billion and issued an initial 2027 outlook calling for $40.0 billion in revenue, according to a regulatory filing reported on October 26 by StockTitan. The updated guidance follows an earlier upward revision and reflects what company leadership, as quoted by StockTitan, described as sustained demand tied to artificial intelligence infrastructure buildouts among hyperscale and frontier AI customers.

What Celestica Disclosed

Per the filing cited by StockTitan, Celestica's 2026 revenue outlook now stands at $21.0 billion, up from a previous outlook of $20.5 billion. For 2027, the company issued its first annual outlook, projecting revenue of $40.0 billion, which the filing describes as growth of roughly 90%. Alongside the revenue figure, Celestica's 2027 outlook includes a record adjusted (non-GAAP) operating margin of 9.0% and adjusted (non-GAAP) earnings per share of $21.50, according to the same source.

Using the two disclosed revenue figures, the implied year-over-year increase from the $21.0 billion 2026 outlook to the $40.0 billion 2027 outlook is calculated as (40.0 - 21.0) / 21.0 x 100, or approximately 90.5%, our calculation based on the company's own disclosed figures as reported by StockTitan. This is consistent with the roughly 90% growth figure cited directly in the filing.

A Rapid Series of Upward Revisions

The $21.0 billion figure represents the latest in a string of raises to Celestica's 2026 outlook. According to reporting by Yahoo Finance Canada, Celestica had previously lifted its 2026 revenue outlook to $20.5 billion from $19 billion, a move the outlet attributed to stronger customer forecasts and improved component supply, representing roughly 65% growth over the prior year. At that time, Yahoo Finance Canada reported that management expected 2027 revenue growth to exceed the roughly 65% pace forecast for 2026, due to both strong customer demand and new business wins. The subsequent update raising 2026 guidance to $21.0 billion and introducing the $40.0 billion 2027 outlook is consistent with that earlier expectation: at roughly 90%, the projected 2027 growth rate sits well above the approximately 65% pace forecast for 2026.

Free Cash Flow Outlook Lowered

Not every metric moved higher. StockTitan reported that Celestica lowered its 2026 free cash flow outlook to $460 million from a previous outlook of $600 million. The filing attributed the change primarily to targeted working capital investments intended to support the accelerating growth anticipated in 2027, according to StockTitan's reporting of the company's disclosure.

Management Commentary on Demand

StockTitan reported that CEO Rob Mionis said Celestica is "well-positioned to continue to support leading hyperscalers and frontier AI labs through the ongoing AI infrastructure supercycle," adding that the demand environment "continues to be very robust, supporting our 2027 revenue outlook, with customer demand forecasts meaningfully higher for 2028." The available disclosure does not break out the 2027 revenue outlook by specific end market, such as hyperscaler AI servers versus networking equipment; the company's public commentary, as reported by StockTitan, names hyperscalers and frontier AI labs as the customer base driving the outlook without quantifying the split between segments.

Market Reaction: A Qualified Read

Recorded closing prices for CLS, per market data from Gentsy, show the stock moving from $300.35 on October 19 to $299.69 on October 20, $304.61 on October 21, then declining to $269.01 on October 22, $260.01 on October 23, and $246.65 on October 26, the day StockTitan reported the filing. Using the October 19 close of $300.35 and the October 26 close of $246.65, the change over that span is calculated as (246.65 - 300.35) / 300.35 x 100, or approximately -17.9%, our calculation based on that recorded price series. This decline occurred across a week that included both the raised 2026 figure and the initial 2027 outlook, making it difficult to attribute the move to any single disclosure from the available price data alone. We would caution against reading a guidance raise as a guaranteed positive catalyst; the recorded price action suggests investors may have been weighing the outlook alongside other factors, including the lowered near-term free cash flow guidance, though the evidence here does not establish a specific cause for the share price movement.

Bottom Line

Celestica's disclosed guidance shows a company raising near-term revenue expectations to $21.0 billion for 2026 while introducing a substantially larger $40.0 billion target for 2027, a jump of roughly 90% by the company's own figures as reported by StockTitan. That growth outlook is paired with a near-term reduction in free cash flow guidance tied to working capital investment, and management commentary pointing to hyperscaler and frontier AI lab demand as the underlying driver. The stock's recorded decline of approximately 17.9% over the week surrounding these disclosures underscores that markets did not treat the guidance raise as an unambiguous signal, and the available evidence does not clarify which specific factors weighed most on sentiment.
