Bilibili 2021 Environmental, Social and Governance Report 4 About the Report Letter from Management About Bilibili 2021 Highlights Responsible Governance Quality Product Responsible Product Creator & Partner Empowerment Human Capital Environmental Protection Creating Social Value Appendix Letter from Management Across a 12-year journey, Bilibili grew from a personal website to the largest online community for young generations in China. While cultural and technological innovations drive the evolution of human civilization, young people are the principal pioneers shaping our culture. As a dynamic community of culture where young people gather, Bilibili continuously strives to enable cultural innovation and bring about positive social changes. This keen sense of purpose runs deep in our unfaltering beliefs. In March 2021, Bilibli was successfully listed on the Hong Kong Stock Exchange, returning to our home capital market. We remain committed to one unwavering vision: to build a stage for content creators where no talent is left unnoticed, to create a welcoming community that users love and appreciate, and to bring original Chinese content to audience worldwide. Just as we are proud to have been one of the most vibrant and creative content communities in China since our inception, our users are delighted to discover enjoyable content on Bilibili, and our creators are proud to identify themselves as "Bilibili Content Creator." It is this myriad of top-notch productions by young and talented content creators that forms Bilibili's diverse content ecosystem. Over the year, the average number of monthly active content creators on Bilibili reached over 3 million, averaging over 10 million video submissions per month. Among our content creators are those who have dedicated themselves to the rejuvenation of Chinese cultural heritage and recreated the gold mask of Sanxingdui, those who have revitalized traditional culture by reinventing classic Chinese opera with popular tunes, and those who have literally turned themselves into a real life 'Iron Man' with self-built mechanical arms and autonomous bicycles... Who would have thought that our content creators, young as they are, would be discussing and exchanging perspectives with top tech leaders? We are delighted that some of them even made a professional career out of a hobby, and are continuously sharing knowledge and happiness with an ever-growing audience. That is living proof of how videomaking creates social value. Great content comes from great content creators, which is why the support to content creators underpins everything we do at Bilibili. Leveraging the various avenues of commercialization we offer, more than 1.3 million content creators generated income on Bilibili in 2021. To further safeguard creators' rights and interests, we launched the "Content Creator Copyright Protection Program" in October 2021, covering over 500,000 content creators. We also stepped up efforts to support our OGV production studios. With the rollout of our "Light Discover Program", we effectively extended support to a wider community of Chinese anime creators. At the same time, we announced an incubation program for documentary filmmakers, "The Darkroom Lamp Program", which enables free creation without concerns. Creation is the change for the better. Positive content enables personal growth for everyone. We emphasize on content informativeness so that our users' time spent on Bilibili is rewarded with knowledge, joy, and inspiration. These "pan-knowledge" videos are perhaps not the most "viral", but also surely the most beneficial to users-they are a more viewer-friendly and efficient means of knowledge sharing, in comparison to pure image or text formats. As such, I believe that in the future all textbook knowledge can be shared through videos that empower engaging and impactful education. In 2021, 190 million users watched pan-knowledge videos on Bilibili, accounting for 45% of all video views on the platform, as useful video content is gaining steam among users. Documentaries, in particular, are a hallmark of the pan-knowledge categories on Bilibili. In November 2021, we hosted our first documentary release press conference, initiating the transition of Internet content from "entertaining" to "enlightening". As of September 2021, over 3,000 documentaries were available on Bilibili, 106 of which were produced in-house. Driven by our global vision, Bilibili-produced content is now headed for the world stage. In November 2021, Bilibili proposed the initiative "Making Chinese Anime Global" in an effort to bring Chinese anime to the overseas market. From documentaries to Chinese anime, we are advancing steadily toward our vision, with 24 Bilibili productions available in various regions around the globe since 2020. It has always been our conviction that a wholesome community helps its members to distinguish right from wrong and good from bad. In our community, we embrace consensus, not disputes. We remove toxic content through a 'self-purification mechanism' to support healthy community development. We have the 'Youth Mode' in place to protect minors from Internet addiction. We offer support through the 'Charging Station' program which connects users with authoritative mental health agencies to address psychological concerns. We set up 'commemorative accounts' for members of the community who have passed away, so that the joy and companionship we shared will live on. Quality and community values has always been our undeviating priorities, which are also engrained in Bilibili's corporate management and development. In 2021, we further integrated ESG values into all aspects of our operations. We held regular expertise sharing sessions to encourage employee growth and personalized development. We continued to advance workplace gender equality by creating a diverse and inclusive work environment. We emphasized on user privacy protection and information security, product and technology innovation and R&D, as well as consistent intellectual property protection and management. Attaching great importance to green development, we closely tracked our carbon footprint and actively advocated for ecological conservation. As the young generations' favourite video community in China, Bilibili not only provides quality content but also expands social responsibility initiatives to align corporate development with societal contribution. We launched the first accessible e-sports live broadcast program for the hearing-impaired, and formulated plans to continuously upgrade accessibility features so that all can enjoy Bilibili at home with ease. On Bilibili's 12th anniversary, we reiterated rural education as the focus of our public welfare programs. We believe lifting children out of poverty is not the sole purpose of rural education. Doubling down on our investment in 2021, we initiated the "Bilibili Happy Scholarships" program to broaden our recruitment reach for rural teachers, to step up rural school construction efforts, and to offer rural teachers stipends for encouraging innovations, and to empower children with an opportunity to explore their interests and the wider world happily and fearlessly. Let me share a story with you about a small child. In a tiny village in Yunnan Province called Naduo, which in the Yi language means "the paddy field nestled behind great mountains", lives the nine-year-old Little Yun'er and her parents, who own a butcher shop. Behind the shop's decrepit door, skinny Little Yun'er is often found doing splits, somersaults and other skillful ballet moves. Dancing is her deepest longing, but an unattainable dream in this mountain village. The Bilibili-produced documentary Little Giants follows her journey in pursuit of her dream. With her talent, Little Yun'er won the hearts of professors at the Beijing Dance Academy, was given the chance to receive proper training, and even earned an opportunity to dance on the stage of China Central Television. Little Giants not only taps into the tender hearts of numerous viewers online but also possibility of a different life, one that children in the mountains may not otherwise have dreamed of. Public welfare is a common cause of the Bilibili community. In addition to specific charity programs, we aspire to sharing dreams, happiness and love with more people. This has led to the launch of the Bilibili Charity Platform, which is recognized by the Ministry of Civil Affairs as part of the third group of designated "Internet fundraising platforms for charitable organizations" for its efforts to bring charity closer to Bilibili's young users while magnifying the social impact of charitable programs. As of today, our platform has featured over 40 charity programs. Committed as always, we continue to practice social responsibility and contribute to positive social development. "Enriching the everyday lives of young generations in China" has been Bilibili's unchanging mission and an integral part of our development plan and corporate values. We will continue to drive outstanding ESG performance with higher standards, make more cultural content innovations, and proactively contribute to the sustainable development of our society. The future is in the making. We are convinced that the tide of "videolization" is high and videomaking will soon become ubiquitous, flourishing in every corner of our day-to-day life. We have faith in that future where tens of millions of talented Chinese content creators deliver best-in-class videos. Riding on the tide of "videolization", Chinese cultural creations are poised to take the world by storm. Mr. Rui Chen Chairman and CEO
