Celestica (CLS) was up 10% on a read-through from Broadcom’s Q3, which beat estimates thanks to strong performance in its AI semiconductor business…

and came with even stronger guidance - with management calling for 66% Y/Y growth in Q4 and a material improvement versus its original 50-60% guide for 2026.

… we’re seeing the growth rate accelerate as opposed to just remain steady at that 50%, 60%. We are expecting and seeing 2026 to accelerate more than the growth rate we see in 2025.

Hock Tan (CEO) - AVGO Q3 call

Supporting that guide are continued share gains at the hyperscalers and a rumoured $10B deal with OpenAI, which was immediately reflected in analyst estimates for Broadcom - but not for Celestica.

Given much of Celestica’s communications business is built around Broadcom chips, it’s reasonable to assume that higher guidance should flow through

and positive estimates revisions should follow - making Celestica’s premium multiple a little more palatable.
