Question · Q4 2025
Todd Coupland asked about the range of outcomes and gating factors for the 1.6T programs to start ramping in the second half of the year.
Answer
Rob Mionis (President and CEO) stated that Celestica has 10 active 1.6T programs, with about 5 ramping in the back half of 2026 and into 2027, and the rest in development for later ramps. He identified the gating factor as completing the development cycle as planned, with silicon on track. Mandeep Chawla (CFO) added that 800G growth is strong, 400G remains resilient, and 1.6T is coming online, noting that next-generation technology is not cannibalizing previous generations, which provides optimism for networking.
