2020 ANNUAL REPORT To Our Shareholders, When I was writing this letter one year ago, the world was entering an unprecedented global health crisis because of the COVID-19 virus, impacting nearly everyone on the planet. One year later, we are still dealing with the pandemic, but we believe the world is beginning to overcome the health crisis due to the rapid rollout and adoption of various vaccines created to protect the global population. It is our hope that you and your loved ones have been kept safe throughout this crisis. We also express our gratitude to the many healthcare workers and first responders worldwide who have cared for and continue to care for those affected and protect those who are vulnerable to this virus. Our annual financial results were significantly impacted by the COVID-19 pandemic. Because of the pandemic, we were forced to close all our parks and dramatically reduce our workforce in March 2020. In June of 2020, we began to re-open some of our parks, following strict health and safety protocols established by federal, state and local authorities. During 2020, we took necessary steps to preserve the Company’s financial position to weather this unprecedented crisis. Today, I am pleased to report that we are planning to have all 12 of our parks open for their 2021 operating seasons. 2020 FINANCIAL PERFORMANCE In February 2021, we reported fourth quarter and fiscal 2020 results that clearly demonstrated our Company’s agility, creativity and determination to operate in one of the most challenging environments we have ever encountered. While the COVID-19 pandemic severely impacted our operations with park closures in the spring followed by restricted openings including capacity limitations, our ambassadors worked collaboratively to find ways to operate within the health and safety guidelines established by federal, state and local governments. I am grateful for their commitment, teamwork and passion as they took care of our guests, our animals and each other throughout this period. In addition, I am pleased that we were able to operate our parks more efficiently than ever before due to our relentless focus on expense management and culture of operational efficiency. We look forward to the time when our parks can return to a more normalized operating environment. We believe there are significant additional opportunities to further improve and enhance our execution and drive meaningful growth in revenue and Adjusted EBITDA when our parks are no longer restricted by capacity limitations, and event restrictions. We have identified meaningful additional cost-savings opportunities that we believe will lead to strong margin improvement in the coming years. We are excited about the future and the opportunity to deliver significant operational and financial improvement that we expect will lead to meaningful increases in shareholder value once we have returned to a normalized operating environment. We want to thank our employee ambassadors for their continued dedication and effort to welcome back our guests while operating our parks in accordance with the latest health and safety protocols. We want to thank our loyal pass-holders and guests for continuing to visit our parks. And, finally we would like to thank our financial and operating partners for their continued support and understanding during these unprecedented times. We have the right assets and team, our balance sheet and liquidity are strong, we are successfully navigating through this extraordinary environment and we are confident we will emerge an even stronger and more profitable enterprise. We continue to have high confidence in our long-term strategy and in our ability to deliver significantly improved operating and financial results that will lead to meaningfully increased value for all stakeholders. Thank you for your investment in SeaWorld Entertainment. Sincerely, Marc G.
