Packaging Corp of America Misses Q4 Estimates on Higher Costs, Weak Volumes; Shares Flat Post-Earnings

Packaging Corporation of America (PKG) reported fourth-quarter 2025 results below Wall Street expectations on February 3, 2026, with revenue and non-GAAP EPS hurt by elevated operating and maintenance costs, lower production volumes, and integration expenses from its Greif acquisition. CEO Mark Kowlzan cited “challenging business conditions,” including outages and unexpected freight and depreciation costs. Analysts are now focused on three key developments: the pace of cost and operational synergies from the Greif deal, the pass-through of announced price hikes in containerboard and corrugated products, and inventory normalization amid shifting end-market demand. PKG shares traded at $223.80 post-earnings, unchanged from pre-announcement levels.
