Thesis

Hyperscaler-driven 800G networking ramp, resilient 400G demand, and AI/ML compute program transition position Celestica for sustained ~20% revenue growth, record margins, and strong FCF into 2026.

Bull case

Multiple 800G wins across all top 3 hyperscalers; 400G volumes remain strong with long tail
Enterprise segment to return to growth in Q4 as AI/ML compute ramps
Record 7.4% operating margin and rising FCF signal strong execution

Bear case

Hyperscaler CapEx could slow if AI demand normalizes
Enterprise AI/ML ramp could face delays or adoption hurdles
Tariff or supply chain shocks could disrupt operations and dent margins

Key Questions

Can Celestica sustain 20%+ revenue growth into 2026 as hyperscaler 800G ramps mature?

Question 2: Will the enterprise AI/ML compute transition ramp on time and at scale to offset past declines?
Question 3: Can record 7.4%+ operating margins be maintained as mix shifts and ATS softens?
