GPK vs PKG stock comparison

Graphic Packaging Holding Co vs PACKAGING CORP OF AMERICA, two Paper & Packaging stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.

Packaging Corp earns nearly double Graphic Packaging's return on equity, 16.16% against 8.44%, and keeps a wider net margin, 8.04% against 3.17%. The market rewards that gap plainly: 29.35 times earnings and 4.69 times book for Packaging Corp, 11.96 times and roughly 1.00 times book for Graphic Packaging. Graphic Packaging also carries heavier debt, 1.9 against 0.86. Its reported free cash flow yield of 27.64% towers over Packaging Corp's 3.26%, but a number that large usually reflects a one-off swing rather than a steady rate, so lean on it lightly. Packaging Corp is the bigger, cleaner, higher-returning operator, priced accordingly at $21.5B against $3.3B.
