The latest results land after a huge run, with Celestica delivering a 234.84% year to date share price return and a staggering 2,906.82% three year total shareholder return, suggesting momentum is still firmly on its side despite recent volatility.

If Celestica’s AI driven surge has caught your attention, this is a good moment to see what else is setting up for growth via high growth tech and AI stocks.

After such a parabolic run, a blowout quarter, and a richer AI narrative, investors are left with a simple question: is Celestica still trading below its true potential, or is the market already pricing in tomorrow’s growth?

Most Popular Narrative Narrative: 21.1% Undervalued

With Celestica last closing at CA$449.52 against a narrative fair value near CA$569.94, the story reflects room for further upside if assumptions hold.

Shifting mix toward high margin end markets (A&D, industrial, healthtech) and value added services (full rack integration, after market, design, and services) is expected to drive net margin expansion and enhance earnings quality, particularly from 2026 onward.

Another View: Rich On Earnings

There is a catch to the bullish narrative. On earnings based valuation, Celestica trades at about 52.2 times profits, versus 24.6 times for the North American Electronic industry and 33.2 times for peers, while our fair ratio sits lower at 48.1 times.

This gap suggests investors are already paying up for flawless execution and sustained AI demand, leaving less room for error if growth or margins wobble. The key question is how much valuation risk you are really comfortable holding at these levels.
