Share Repurchase Program

On January 26, 2022, PCA announced that its Board of Directors authorized the repurchase of $1 billion of the Company’s outstanding common stock from time to time in open market or privately negotiated transactions in accordance with applicable securities laws. At the time of the announcement, there was no remaining authority under previously announced programs. Repurchases may be made from time to time in open market or privately negotiated transactions in accordance with applicable securities regulations. The timing and amount of repurchases will be determined by the Company in its discretion based on factors such as PCA’s stock price and market and business conditions.

During the fourth quarter of 2025, we paid $153.0 million, including fees, to repurchase 0.8 million shares of common stock. At December 31, 2025, $283.1 million of the authorized amount remained available for repurchase of the Company’s common stock. All shares repurchased have been retired. The Company did not repurchase any shares of its common stock under this authority during the year ended December 31, 2024. During the third quarter of 2023, we paid $41.5 million, including fees, to repurchase 0.3 million shares of common stock.

Pursuant to its equity incentive plan, the Company withholds shares from vesting employee equity awards to cover employee tax liabilities. We withheld 118,675 shares in 2025 to cover $23.6 million in employee tax liabilities, 142,552 shares in 2024 to cover $25.7 million in employee tax liabilities, and 120,534 shares in 2023 to cover $15.7 million in employee tax liabilities.
