Question · Q4 2025
Robert Young asked for context on the third hyperscaler 1.6T win, specifically if it was an extension of 800G, tied to Tomahawk ASIC experience, or part of a rack integration. He also inquired about how operating margins are expected to evolve with 1.6T programs, and how margin structure might differ between full rack deployments and standalone programs.
Answer
CEO Rob Mionis explained that the third 1.6T win is an extension of an existing relationship where Celestica had predominant share on 400G and 800G with that hyperscaler, awarded based on design win and performance. CFO Mandeep Chawla stated that 1.6T programs are expected to be as profitable as past switching programs, with higher margins during ramp/development and offset by operating leverage in mass production. He noted a trend towards more HPS in the switching portfolio, leading to better pricing, and for full rack deployments, they look at it holistically, capturing value from switching, compute, integration, and testing.
