Management Feature 2022 ESG Performance Co-creating Value with Users Co-creating Value with Partners Co-creating Value with Society Corporate Governance About the Report Appendix Bilibili 2022 Environmental, Social and Governance Report 3 In the spring of 2022, Bilibili’s tech content creator, MediaStorm, received a special message from a fan. “I wonder what it would be like for me to run if I hadn’t lost my legs,” the message read. The sender, a young boy named Shaoxuan, had lost both legs in a car accident when he was only seven years old. He was no longer able to run and play freely like other children, which was misfortune that he bore. Shaoxuan hoped that MediaStorm, who is experienced in motion graphics and visual effects, could use their skills to let him see himself running again. Despite feeling apprehensive about the visual effects, the MediaStorm team worked tirelessly for nine months to film and post-produce the video aiming to help the boy “get back on his feet” and start running again in the video. Shaoxuan’s journey to fulfill his dream has touched the hearts of many, and his dream-come-true video on Bilibili has garnered over 8 million views. Users on the platform shared their emotions, highlighting the profound significance of technology that goes beyond efficiency. One of the users commented, “The meaning of technology is not just to aid humanity in exploring the unknown, but also to allow more people to see the beauty of this vast world through helping others.” Inspired by MediaStorm’s support, Shaoxuan became a Bilibili content creator himself, using videos to document his life experiences as a person with disabilities. MediaStorm and Shaoxuan’s touching story is just a microcosm of the many stories on Bilibili. Every day, millions of content creators share their daily lives on our platform, spreading warmth and hope to society through the community. As Bilibili celebrated its 13th anniversary in 2022, we looked back on our journey and how far we have come. From our beginnings as a small personal website, we have evolved into one of the largest youth cultural community in China. We are grateful for the privilege of accompanying generations of users on their personal journeys and for the opportunity to witness their growth into knowledgeable, responsible, and accomplished young adults. We encourage content creation, particularly pan-knowledge content, to deliver both value and fun, hoping to inspire our users to engage with entertaining but thought-provoking content. We take the mental health of teenagers seriously and constantly refine our Youth Mode to ensure that they are well-protected. We are also dedicated to supporting charitable causes and continuously provide assistance to rural education, with the ultimate goal of providing equal and high-quality education opportunities to all children in China, regardless of their background. Over the past year, a significant number of new users have joined Bilibili, with an average age of just over 20 years old. These users are at a stage in life where they crave knowledge and wish to embrace the bigger world. Our users often say, “Everyone knows Bilibili is an app for learning,” and they are right. Bilibili might boast the most extensive collection of educational videos among all Chinese streaming platforms. Our young users can explore a variety of topics on Bilibili, from marine geology with Academician Wang Pinxian to cutting-edge AI facts with Li Mu (a former chief scientist at Amazon and lecturer at Stanford). There are also streaming documentaries like The Land of Spirits to broaden their horizons with diverse subjects. Bilibili today has also emerged as a leadin platform for high-quality content on AIGC, spurred by the global AI revolution. This rise of pan-knowledge content on Bilibili represents a shift among Gen Z+ in China towards online content that is increasingly focused on knowledge rather than simplistic entertainment. We also hope that no matter what age our users discover and fall in love with Bilibili, we can provide them with useful and interesting content, becoming an important companion in their lives. Many of our earliest users who joined Bilibili 13 years ago are now in their thirties and entering a new phase of life. In the past year, many users have turned to Bilibili to learn career skills to boost their professional growth. Some have shared and learned about parenting on Bilibili, embracing their new role as parents, while others have followed our content creators to learn how to select home appliances and decorate their apartments to create their first cozy nests. The valuable and engaging content shared by our creators has further enriched Bilibili’s diverse range of content offerings. In the past 13 years, many Bilibili users have not only expanded their knowledge and gained happiness in the community but also found like-minded companions and considered Bilibili as their spiritual sanctuary. Meanwhile, to bring more harmony and positivity to our community, we use an automated system to filter out negative interactions and have implemented various measures to address issues like online bullying and low-quality content. Since 2019 we have launched many protective features, including our Youth, Mode, parental controls, and the Family Platform to promote responsible use and prevent addiction. Additionally, our Charging Station program provides emotional support for users. In the last year, we also partnered with institutions like the Shanghai Mental Health Center to offer professional support. We believe it is our calling as a company to go beyond just products and services and actively take on social responsibilities by creating positive value for our society. We leverage our leading video community to advocate charitable ideas and encourage young users to get involved. In 2022, we launched the Bilibili Charity Platform, designated as one of the Ministry of Civil Affairs’ third series of online fundraising information platforms for charitable organizations. As of the end of 2022, the Platform had 55 charity programs and raised over RMB5 million from more than 310,000 donors. Rural education has always been a priority for Bilibili’s charitable efforts. We aim to provide better educational resources for children, broaden their horizons, and help them discover a bigger world. Last June, we supported the construction of Bilibili Yili Primary School in Yunnan province, marking the fifth rural school that we have supported building. We also utilize our unique resources and partner with content creators to produce high-quality video courses that make learning enjoyable for children. On our 12th anniversary, we established the Bilibili Happiness Scholarship to bring warmth and joy to rural students and teachers. As of January 2023, we had awarded nearly RMB700,000 in scholarships to support extracurricular programs and student interest clubs at these schools. We believe that videolization is the inevitable trend, with video content becoming the mainstream of online content. We also believe that good content carries value in itself, and as we continue to support outstanding content creators on their creative journeys, we also seek to deliver a fulfilling experience to our users. Bilibili will continue to provide high quality content to enrich the everyday life of young generations in China and accompany them on their personal journey. At the same time, we are committed to improving our ESG governance standards and actively fulfilling our corporate social responsibility to contribute to the sustainable development of society. Rui Chen Chairman and CEO

The 2021 Sustainability Bond aimed at financing projects that are expected to reduce the environmental impact of the Company’s operations while increasing access to education and providing other social benefits in China. In February 2023, Bilibili engaged Sustainalytics to review the projects funded with proceeds from the issuances (the “Nominated Projects“) and provide an assessment as to whether the projects met the Use of Proceeds criteria and the Reporting commitments outlined in the Bilibili Sustainable Finance Framework. Sustainalytics provided a second-party opinion on the Framework in November 20212, and a previous annual review in April 2022.3-4 Evaluation Criteria Sustainalytics evaluated the Nominated projects funded between March 2022 to January 2023 based on whether they: Met the Use of Proceeds and Eligibility Criteria outlined in the Framework; and Reported on at least one of the Key Performance Indicators (KPIs) for each use of proceeds criteria outlined in the Framework.
