Talent Acquisition and Retention Where retention issues are concerned, we realize that some individuals’ decisions might be based on factors beyond our control as a company. Our turnover rates are in keeping with global trends, such as the U.S. labor shortage and a booming competitive market for talent around the world. We are actively meeting the challenges created by the current employment climate, as we are intentionally building the workforce of the future and creating an environment that is attractive to the next generation of employees. Overall turnover increased to 20% + in 2021, up from 16% in 2020. This increase was driven by higher turnover among our primary employees, which was 23.8% + in 2021. Turnover among staff employees was 10.6%, a decline that was driven mainly by a sharp reduction in involuntary terminations in 2021. + Retention 100% retention of high-potential talent between annual talent reviews. + We want to ensure that our top talent remains proud members of the Owens Corning team. According to the Society for Human Resource Managers (SHRM), this is the top quartile for outstanding companies, which makes it a suitable goal for Owens Corning. 2030 TARGETS & PERFORMANCE 2030 Percentage of High-Potential Talent Retained GOAL: 100% 96% 2021 201 8 BASE YEA R 96 % 98% 2019 97% 2020
