Celestica’s Post-Meltdown AI Narrative: New Wins Meet Lingering Risks

What happened

Celestica’s stock plunged roughly 33% from April highs, but a bullish Seeking Alpha piece now touts expanded AI partnerships with AMD, OpenAI, and Broadcom as proof of premium growth. Management has twice raised fiscal 2026 guidance and offered an outsized 2027 outlook, suggesting AI infrastructure demand remains robust. At a trailing P/E of 28.9x and a three-year PEG of 0.44, the article argues the sell-off has created a compelling entry point. However, the DeepValue master report underscores extreme customer concentration, a risky $1 billion capacity ramp, and working-capital strains that the article overlooks. While the lower price improves the risk/reward, the core fragility from hyperscaler timing and utility bottlenecks persists, keeping the wait-and-watch stance intact for now.

Implication

For investors, the lowered valuation and raised guidance make the stock more attractive than a few months ago, yet the DeepValue report’s risk factors remain unresolved. The new customer wins with OpenAI and Broadcom could diversify the hyperscaler exposure, but the company has not yet demonstrated stable cash conversion alongside the capacity expansion. The thesis rests on whether the raised $19 billion revenue and $10.15 EPS targets for 2026 are achievable without customer pushouts or margin erosion. Given the price drop, the risk/reward has shifted favorably, but only if the next quarters confirm that program delays are not materializing and CCS margins hold above 8.5%. A disciplined approach would be to build a position gradually, while monitoring the 90-day checkpoints for any signs of execution failure or demand air pockets.

Thesis delta

The deep pullback from $420 to sub-$250, combined with raised guidance and new high-profile customer wins, shifts the rating from outright WAIT to a cautious BUY at these levels. However, the high concentration and capex execution risk necessitate a phased entry, with the conviction tempered until the next quarterly filing validates demand stability and margin durability.
