Approach 1: Smurfit Westrock Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model takes expected future cash flows, then discounts them back to what they could be worth in today’s money. It is essentially asking what those future dollars might be worth right now.

For Smurfit Westrock, the model uses a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $1.17b. Analyst inputs and Simply Wall St extrapolations project free cash flow rising to around $4.56b in 2035, with interim estimates such as $1.52b in 2026 and $2.93b in 2029, all in $.

Discounting those projected cash flows back to today produces an estimated intrinsic value of $116.43 per share. Compared with the recent share price around $39.68, the DCF output implies the stock is about 65.9% undervalued based purely on these cash flow assumptions.

Approach 2: Smurfit Westrock Price vs Earnings

The P/E ratio is a common way to assess valuation for profitable companies because it compares what you pay for each share with the earnings that share currently generates. In general, higher expected earnings growth and lower perceived risk can justify a higher “normal” P/E, while lower growth prospects or higher risk can point to a lower one.

Smurfit Westrock currently trades on a P/E of 29.69x. That sits above both the Packaging industry average P/E of 15.70x and the peer group average of 20.26x. Simply Wall St’s Fair Ratio for Smurfit Westrock is 30.39x, which is a proprietary estimate of what the P/E might be given factors such as earnings growth profile, industry, profit margins, market cap and specific risks.

This Fair Ratio can be more informative than a simple comparison to peers or the industry, because it adjusts for the company’s own characteristics rather than assuming all packaging stocks should trade on the same multiple. With the current P/E of 29.69x sitting very close to the Fair Ratio of 30.39x, the multiple suggests the shares are priced at roughly the level implied by these fundamentals.
