Packaging Corporation of America’s SEC filings document results, governance, capital structure, and material events for a NYSE-listed operating company in containerboard products, corrugated packaging, and uncoated freesheet paper. Its Form 8-K reports furnish quarterly and full-year financial results, Regulation FD investor presentation materials, and notices involving directors, officers, and compensatory arrangements.
The filing record also includes a definitive proxy statement covering annual-meeting governance matters and disclosures on common stock registered under Section 12(b). Material-event filings describe financing arrangements, direct financial obligations, and the completed acquisition of Greif’s containerboard business, including added mill and corrugated-plant assets.
Packaging Corporation of America (PKG) filed a Form S-3 shelf registration prospectus dated August 11, 2025 to permit offers and sales of an indeterminate aggregate amount of debt securities from time to time. The prospectus describes general terms and the process for future offerings and states that specific terms (amounts, interest rates, redemption, maturity, currencies, trustees and distribution arrangements) will be provided in prospectus supplements.
The company describes its operations (eight mills, 85 corrugated products plants, and reporting segments: Packaging, Paper and Corporate and Other), intended uses of net proceeds (repayment of indebtedness and general corporate and working capital purposes), and the governing indenture dated July 21, 2003 with U.S. Bank Trust Company as trustee. Key indenture features disclosed include lien and sale-and-leaseback limits (aggregate incremental secured indebtedness and sale-leaseback attributable value not to exceed 10% of Consolidated Net Tangible Assets), Principal Property threshold (> 1.0% of Consolidated Net Tangible Assets), and an Event of Default acceleration threshold for other indebtedness of $30,000,000. The filing defers the SEC registration fee as the aggregate amount is indeterminate and incorporates by reference the 2024 Annual Report and 2025 quarterly and current reports listed in the prospectus.
