Bottom line
The sleeper story is CLS has already achieved 800G manufacturing leadership with higher market share than they had in 400G, setting up multi-year dominance as hyperscalers race to upgrade infrastructure. The Street sees 'another beat and raise' but misses that management is deliberately sandbagging; they admit customer demand exceeds the raised $11.55B guide. The binding constraint isn't demand or capacity (they can support $3-4B more revenue), it's component availability and tariff uncertainty that's forcing conservative guidance. Mandeep revealed the key: 'Our demand outlook is higher than that... we're just taking into account challenges.' My view changes if 800G mix doesn't exceed 50% in H2 or if enterprise doesn't inflect positive in Q4.

The 30-second version

  • 800G networking at parity with 400G volumes in Q2, accelerating in H2 while 400G has 'very long tail'
  • HPS revenue hits $1.2B (43% of total), up 82% YoY, but enterprise AI/ML compute transition masks underlying strength
  • Management raising guidance but admits customer outlook is HIGHER than guided $11.55B
