Celestica Raises 2026 Guidance; AI Demand Visibility Extends to 2029

What happened

Celestica raised its 2026 guidance to $20.5 billion in revenue and $11.30 in adjusted EPS, up from prior targets of $19.0 billion and $10.15, driven by accelerating AI infrastructure demand. Q3 year-over-year revenue growth is approaching 69%, supported by component lead times exceeding 52 weeks that are forcing customers into binding commitments and giving Celestica demand visibility through 2028 and 2029. The company cited ten 1.6T programs, co-packaged optics (CPO), AMD Helios, and OpenAI Jalapeño as overlapping ramps that extend well beyond 2026. While the raised guidance underscores the strength of hyperscaler AI spending, the company remains exposed to customer concentration, with three customers representing 35%, 15%, and 15% of revenue in Q1 2026. The critical near-term execution risks include capacity ramp delays due to utility/grid constraints and working-capital strain from elevated receivables sales.

Implication

The raised guidance and extended component commitments improve the earnings visibility for Celestica through 2029, supporting a more bullish operational outlook. However, the stock trades at 43.3x P/E and 34x EV/EBITDA based on the last reported price, leaving little margin for execution missteps. The key monitorables are CCS segment margins staying above 8.5%, receivables sales declining below $100 million per quarter, and no disclosures of program delays due to power or grid constraints. If these conditions hold over the next one to two quarters, the stock may warrant an upgrade to an accumulate rating. Until then, investors should wait for a better entry point, preferably near $300, or evidence that the capacity ramp is fully operational without demand slippage.

Thesis delta

The thesis shifts more bullish on demand durability, as component commitments now extend visibility through 2029, reducing the risk of a near-term air pocket. The raised guidance supports the bull case, but the unchanged risks—customer concentration, utility constraints, and working-capital strain—keep the valuation from offering a margin of safety at current levels. The overall view retains a WAIT rating, with the attractive entry point unchanged near $300 and the trim level above $420.
