Celestica (TSX:CLS) Stock May Be 37% Undervalued On AI Funding Raise

Simply Wall St · 2d ago

Celestica’s share price has climbed very sharply over the past five years, yet the stock still screens as undervalued on both intrinsic value estimates and earnings based checks, which raises the question of how much of that move is backed by fundamentals.

  • Celestica has delivered a very large 5 year return of about 40x, which puts extra focus on whether today’s price still leaves room for a reasonable margin of safety.
  • The recent equity raise of about US$3.45b to support AI infrastructure and data center networking can support long term growth, while the increased share count and the need to deploy that capital effectively may weigh on the valuation if execution falls short.
  • The broader valuation checks lean cheap, with Celestica screening as undervalued on 5 of 6 measures, which you can see in more detail in the value score.

The issue now is whether Celestica’s current market price already reflects the upside implied by the intrinsic value estimate or still leaves a meaningful discount in place.

Celestica delivered 55.1% returns over the last year. See how this stacks up to the rest of the Electronic industry.

Does Celestica Look Undervalued on Cash Flow?

The Discounted Cash Flow (DCF) model takes Celestica’s projected free cash flows and discounts them back to today. Based on this framework, the company is generating last twelve month free cash flow of about $731 million and the model assumes those cash flows grow from this base over time, rather than shrinking.

Under these assumptions, the DCF model arrives at an estimated intrinsic value of about CA$699 per share. This implies the stock trades at roughly a 36.6% discount and therefore appears undervalued on this measure. The recent CA$3.45 billion equity raise to fund AI infrastructure and data center networking helps explain why the market is focusing on execution risk, even though the cash flow outlook used in the model suggests more support for the current price.

Overall, the DCF analysis indicates Celestica stock currently appears undervalued relative to the cash flows implied in this model.

Is Celestica a Bargain on Earnings?

The P/E ratio is a useful way to check how much you are paying for each dollar of Celestica’s earnings today. It links directly to the company’s bottom line, which many investors watch closely.

Celestica trades on a P/E of about 32.8x, which sits above the Electronic industry average of 28.3x but below the peer group average of 44.7x. The Fair Ratio model, which looks at factors such as growth, margins, industry position and risk, points to a higher P/E of roughly 53.6x as a reasonable reference point for the stock.

That leaves Celestica trading at a discount to the level suggested by this tailored benchmark, even after the strong interest around its AI and data center exposure. On this framework the current multiple does not fully reflect the earnings profile implied by the Fair Ratio.

On the P/E multiple, Celestica stock currently appears inexpensive relative to the earnings level suggested by the Fair Ratio model.

The Bottom Line

Celestica screens as undervalued on both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiple work, and the broader valuation checks also lean in the same direction. That points to a story where the market is still applying a clear discount even after a very strong 5 year share price move. The crux now is whether Celestica can deploy its recent equity raise into AI and data center projects with enough discipline that cash flows and margins track the optimistic scenarios already outlined. If that execution stalls, what looks like a discount today could instead prove to be a value trap.
