The main risk is not whether AI infrastructure demand exists, but whether Celestica captures durable value from it. A few giant customers control outcomes, the business is absorbing unusual
capex and working-capital intensity, and external power or deployment bottlenecks can delay shipments even if Celestica executes well. If the company proves that AI volume also improves mix, service attach, and returns on capital, risk falls quickly; if not, the market can
re-rate it back toward ordinary manufacturing.
