Phillips 66

Phillips 66 employees, our human capital, are guided by our values of safety, honor and commitment. Together, we operate as a high-performing organization by building breadth and depth in capabilities, pursuing excellence and doing the right thing. We empower our people to create and innovate, and to work in ways that are designed to enable us to deliver industry leading performance. At December 31, 2024, we had approximately 13,200 employees working toward our mission of providing energy and improving lives and our vision to be the leading integrated downstream energy provider.

We believe maintaining and enhancing a high-performing organization is critical to our success. Our employees promote our culture and are integral to achieving our strategic priorities and maximizing long-term shareholder value. We strive for continuous improvement of our high-performing organization, as we believe that our employees differentiate us in the marketplace. The human capital measures and objectives that we focus on in managing our business and that we believe are important to understand our business, include:

•Safety—Safety is the cornerstone of our business. We endeavor to protect the health and safety of everyone who has a role in our operations and the communities in which we operate. We employ rigorous employee training and audit programs to drive ongoing improvement in personal safety as we strive for zero incidents. We include environmental and safety metrics in our annual incentive compensation program, including our total recordable rate and process safety event rate, to incentivize and reward safe operations. Under the variable cash incentive program, our personal safety performance is measured by our total recordable rate (TRR), which measures the number of incidents per 200,000 hours worked. In 2024, our combined workforce TRR of 0.12 was 23 times better than the U.S. manufacturing average.

•Culture—Phillips 66 seeks to foster behaviors that support our culture. “Our Energy in Action” is a set of core behaviors embedded in the company’s talent and business processes to drive performance and accountability. Those behaviors include working for the greater good; creating an environment of trust; seeking different perspectives; and pursuing excellence.

In addition, we believe a high level of performance can be achieved through an inclusive culture that supports equal opportunities. Our Executive Inclusion and Diversity and Culture Council, chaired by our Chairman and Chief Executive Officer and comprised of executives and business leaders that serve as global sponsors of our ten Employee Resource Groups (ERGs), supports our goal to build an inclusive culture.

Our ERGs are grassroots organizations, available to all employees, and are focused on professional development, networking, community involvement and supporting Phillips 66 recruiting activities.

We regularly conduct employee engagement surveys that enable us to capture real-time feedback on metrics such as employee engagement, manager effectiveness, performance enablement and our culture. Management analyzes the findings from the survey to monitor our progress and identify potential areas of opportunity.

•Capability—We strive to build depth and breadth in the skills of our employees to create a workforce ready for the future. We drive employee development through technical training and providing opportunities for job rotations, as well as assisting employees with obtaining and sharpening managerial skills through targeted development programs and promotional moves. Our performance management process is designed to identify coaching and training needs.

We also have robust succession management practices and work each year to identify successors for key leadership positions within the company.

•Performance—We focus on delivering exceptional, sustainable results. We work towards retention of top talent and have advanced the effectiveness of our performance management process by embedding “Our Energy in Action” into the process to help drive desired behaviors. Additionally, “High Performing Organization” is one of the metrics used in our variable cash incentive program. In assessing our “High Performing Organization,” we measure success in areas such as culture, engagement, talent, technology, human capital management, and our organization’s ability to adapt and respond to challenges, changing market conditions and other external factors.
