Gray Oak Pipeline Wink Facility WINK, TX CONTENTS 1 LETTER FROM OUR CHAIRMAN AND CEO FINANCIAL HIGHLIGHTS INTEGRATED PORTFOLIO STRATEGY LEADERSHIP NON-GAAP RECONCILIATIONS Our 2020 financial performance reflects the challenging market conditions caused by the COVID-19 pandemic. We had a loss of $4 billion, or $9.06 per share. On an adjusted basis, this was a loss of $382 million, or $0.89 per share. In 2020, we generated $2.1 billion of operating cash flow, demonstrating the strength of our diversified portfolio despite the unprecedented demand destruction for refined products. We reinvested $2.9 billion back into the business and returned $2 billion to shareholders through dividends and share repurchases. We took early, decisive steps to support our liquidity and position us to navigate the uncertain environment. We exceeded $500 million in cost reductions and cut capital spending by more than $700 million. We secured additional liquidity in the debt markets and suspended our share repurchases. These actions, combined with our cash flow generation, provided us with financial flexibility to maintain our strong investment grade credit ratings and sustain the dividend. Since the formation of the company in 2012, we have returned approximately $28 billion to shareholders through dividends, share repurchases and exchanges. Operating excellence is the first pillar of our strategy, and it is essential to everything we do. Our goal is zero incidents, zero accidents and zero injuries. We believe this is attainable, and we strive for it every day. • In 2020, our combined workforce total recordable rate of 0.11 was 30% better than our industry- leading rate in 2019 • Our lost workday case rate was 0.02, approximately 75% better than the U.S. refining industry average • For the fourth year in a row, at least one of our refineries received the AFPM’s Distinguished Safety Award, the highest annual safety recognition in the industry • Our process safety event rate improved by 60%, and our environmental performance was our best ever We also give back to the communities where we live and work through direct financial support and volunteerism by our employees. In 2020, we contributed $32 million to charitable organizations, including almost $6 million toward COVID-19 and disaster relief. Since we formed as a company in 2012, our employees have donated approximately 522,000 hours of their time to charitable and service organizations. 2 PHILLIPS 66 2020 YEAR IN REVIEW Greg Garland “2020 was the safest year in the history of Phillips 66.” 2020 brought many unforeseen challenges to our business. Our employees remained focused and committed to executing our strategy and delivering on our vision to provide energy and improve lives. Looking forward, we are optimistic about the positive impact the vaccines will have on economic recovery in the months ahead. As we come out of the pandemic, our strategy remains focused on growth, returns and distributions supported by a strong foundation of operating excellence and our high-performing organization. We will continue to deliver on our vision to provide energy and improve lives while also playing a key role in developing solutions for the climate challenge.
