To Our Stakeholders, Each year, as we report our sustainability efforts, we are afforded a chance to reflect on our successes and acknowledge the work that still lies ahead. On May 1, 2022, we celebrated 10 years of providing energy and improving lives at Phillips 66. It's been a decade of progress built on our nearly 150-year heritage. Our high-performing organization stands on our values of safety, honor and commitment and remains focused on operating excellence, growth, returns and distributions. We are experts in making and moving the energy of today, and we are motivated by the opportunities we see all around us to optimize our businesses to thrive as energy systems evolve. That's why we are strengthening our core businesses, expanding our digital capabilities, using technology to improve operating efficiencies and transforming our organization to increase productivity. We have ambitious goals, and we’re taking deliberate steps to achieve them. You’ll also read in this report about our Emerging Energy group, introduced in 2021, and its focus on renewable fuels, batteries, carbon capture and hydrogen. You will also read about Rodeo Renewed, which is transforming our San Francisco Refinery in Rodeo, California, into one of the world's largest renewable fuels plants. Here, we detail how, in the United Kingdom, our Humber Refinery is an example of the future of refining. Its sustainable aviation fuel is now powering flights for British Airways, and it stands poised to be the first refinery in the world to use a promising new carbon capture technology. These projects and others — like our investments in the U.S. battery chain and our joint venture to build a network of hydrogen fueling stations in Europe — are tangible steps toward our 2030 and 2050 GHG emissions reduction targets. As we move forward, we will strive to be capital-disciplined, energy efficient and supportive of our stakeholders. Throughout this report, you'll read about how we're working with new and existing companies, bringing fresh perspectives and finding creative solutions to the challenges of our time. Innovation is part of who we are, and it is driven by our employees. They are empowered to think big, try new things and develop solutions that advance our priorities and position our company for long-term resilience. This year, as we transition CEO leadership at Phillips 66, we are all guided by our vision of providing energy and improving lives, inspired by our culture and values, and intently focused on being the best operator in the business. Thank you for your interest in Phillips 66. We welcome your feedback.
