Armstrong World Industries Retirement Savings Plan

It is the defined benefit corporate pension plan sponsored by Armstrong World Industries, the publicly traded ceiling and wall systems manufacturer headquartered in Lancaster, Pennsylvania. The plan covers current and former Armstrong employees and is funded by company contributions. Its investment portfolio is managed to meet long-term pension obligations.

Armstrong World Industries maintains a traditional defined benefit pension plan, though the exact current accrual status — whether it remains open to new participants or has been frozen — is not publicly detailed in aggregated disclosures. The plan sits alongside Armstrong's 401(k) offering as part of the company's overall retirement benefits package.

Based on standard Form 5500 filings for corporate pension plans of this size, the portfolio likely includes a mix of domestic and international equities, fixed income securities, and allocations to private market funds through external managers. Armstrong does not publicly market its pension investment strategy, and the plan does not operate as a direct investor.
