PACKAGING CORP OF AMERICA

PCA’s success depends on a highly engaged, results-oriented workforce operating in an entrepreneurial culture. Our primary objective is to place the right people in the right roles and empower them to succeed.

Safety is a core value at PCA and we believe that all accidents are preventable and an injury-free environment is achievable. We have implemented a robust occupational health and safety management system to assure accountability throughout the organization for safe work practices. Key components to our system include commitment from management, extensive training of employees, hazard identification and communication and regular safety audits.

PCA has, at times, experienced labor shortages and/or higher than historical employee turnover in certain of our facilities. However, PCA has not experienced significant disruptions in its operations and has managed to maintain adequate availability of its workforce and supply of raw materials and services to continue to serve its customers.

We have extensive recruiting, training and development programs designed to attract and retain a highly talented workforce aligned with our objectives to relentlessly serve our customers and achieve operational excellence throughout our organization. As demand for qualified personnel is increasing, we are expanding our efforts in these critical areas along with efforts to continue to develop, promote and maintain a workforce with a culture and an environment of engaged management and mutual respect. We publicly disclose in our annual responsibility report our employee demographics in the form of our annual EEO-1 report. Our responsibility report is available on our website and is not intended to be incorporated by reference herein.

PCA regularly conducts employee engagement surveys to measure overall satisfaction and gain a deeper understanding of how to improve our employees’ work experience. Our most recent survey, conducted in 2024, saw a high level of participation assuring us that the results reflect the feelings and opinions of our employees. Our survey results reaffirmed our strong safety culture and our dedication to being socially and environmentally responsible. Our overall engagement index continues to rise and remains consistent with other U.S. manufacturing companies. We remain committed to seeking feedback from our employees as we work together to make meaningful improvements across our operations and make PCA a great place to work. Our next employee engagement survey will be conducted as scheduled in the first half of 2026.

As of December 31, 2024, we had approximately 15,400 employees, including 4,300 salaried and 11,100 hourly employees. Approximately 60% of our hourly employees worked pursuant to collective bargaining agreements. The majority of our unionized employees are represented by the United Steel Workers (USW), the Printing Packaging Production Workers Union (PPPWU), the Association of Western Pulp and Paper Workers (AWPPW), the International Association of Machinists (IAM), and the International Brotherhood of Teamsters (IBT). We are currently in negotiations to renew or extend union contracts that have expired or are expiring in the near future. During 2024, we experienced no work stoppages, and we believe we have satisfactory labor relations with our employees.
