Centene is committed to actively seeking and acting on feedback from our employees through our "Shaping Centene" program, which consists of a series of enterprise- wide surveys. These surveys measure overall engagement and focus on specific themes such as leadership effectiveness and our efforts to foster a diverse, equitable, and inclusive workplace. By continually evolving and acting on the feedback we receive, we strive to strengthen our culture of engagement and create an environment where all employees feel valued and heard. Our employee engagement surveys are administered by Perceptyx.

The Engagement Index is calculated based on responses to three engagement questions from the survey. The numerator represents the total count of favorable responses ("Strongly Agree" or "Agree") across all three questions, while the denominator represents the total count of valid responses. Overall engagement is represented as the percentage of favorable responses out of all responses received for the three engagement questions.

Additional information regarding our employee engagement survey is available on page 46 of our 2023 Sustainability & DEI Report.
