Graphic Packaging Holding Co vs Smurfit Westrock plc, two Paper & Packaging stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
Smurfit Westrock's profits are still buried under merger-integration costs, so its 65.26 times earnings and 2.1% return on equity read low for a temporary reason. Graphic Packaging, working through no such distortion, earns 8.44% on equity at 11.96 times earnings. The two trade near book, 1.00 times for Graphic Packaging and 1.37 times for Smurfit Westrock. Their debt loads sit at opposite ends: Graphic Packaging carries 1.9, Smurfit Westrock almost nothing at 0.05. Graphic Packaging's 27.64% free cash flow yield looks huge next to Smurfit Westrock's 4.13%, but a figure that size usually reflects a one-off and should be treated with caution. Smurfit Westrock is far larger, $24.7B against $3.3B.
