Management’s Highlights Honors & Awards Creating Community Value Enhancing Industry Value Building Social Value Corporate Governance About the Report Appendix Bilibili 2023 Environmental, Social and Governance Report Letter 02 Management’ s Letter When AIGC was first trending last March, our content creator San Yue Yu A Gou approached ChatGPT with a heartfelt query:“My mom passed away when I was seven. Will you be my mom?” In the four-minute video, ChatGPT’s final words deeply moved audiences:“I’ m the mom who adored you at seven, forever young, forever by your side.” This video eventually gained more than 2 million views. I believe what touches us most is not merely the technology, but the genuine feelings underlying it. At Bilibili, countless heartfelt, heartwarming and deeply touching stories like this one unfold every day. Millions of content creators share their personal journeys and moments of happiness, spreading warmth and hope to society. We feel so lucky to be a witness, recorder and participant in their growth and joy. 14 years ago, we started as a small, personal website. Over time, as waves of new users came on board, existing users also embarked on new chapters of their lives. In the second half of last year, we achieved a significant milestone by surpassing 100 million DAUs, with average users’ daily time spent exceeding 95 minutes. This reinforces our position as a mainstream content community in China while also placing greater responsibilities and expectations upon us. I believe Bilibili goes beyond being an internet company; we are also a cultural enterprise. Our goal is not only generating commercial value, but also creating social value. We encourage the creation of useful, high-quality video content, hoping that users on Bilibili can not only find joy but also learn and grow. We care about healthy development of teenagers and continually refine our anti-addiction features to safeguard these minors’ growth. We are committed to philanthropy by continually investing in rural education. We hope to ensure that all children, regardless of their backgrounds, have equal access to education. On Bilibili, young generations are passionate about learning in-depth knowledge. Animated presentations of advanced mathematics, Stickman vs. Mathematics, is one of our most popular videos. They learn how to perceive the world and themselves from renowned teachers like Professor Wang Defeng. Through high-quality documentaries like Planet Earth, they explore the world and broaden their horizons. Over the past year, over 200 million users studied on Bilibili. On average, more than 20 million users watched technology- and science-related videos on Bilibili every day. Interest-driven educational videos gained more than 44 billion views in 2023. The extensive, high-quality content on our platform has made Bilibili a reliable mentor and partner for the youth in their growth journey. A number of esteemed educators and industry experts have joined Bilibili, aiming to break down education barriers and share knowledge with young people in a vivid and interesting way. As of the end of 2023, three Nobel Prize winners, 645 professors and scholars have joined Bilibili, and the number of technology-related content creators reached 1.16 million. Over the past year, some of our users have joyfully embraced parenthood, sharing their firsthand parenting experiences on Bilibili. Others have celebrated the excitement of moving into their first homes, eagerly documenting their home decoration journeys and sharing their joy. For those who recently acquired their first cars, they cannot wait to share stories of their road trips and the beauty of the landscape. Additionally, some first-time travelers meticulously crafted helpful guide videos on navigating high-speed railway ticket purchases. Some have dedicated their efforts to creating specialized equipment for gamers with disabilities, while others have immersed themselves in charitable endeavors, such as organizing fashion shows for children in rural areas. The interesting and useful content shared by these content creators and users make our platform even more diverse and engaging. We believe that helping content creators earn income is the most practical way to support their continuous creations. In 2023, over 3 million content creators earned income on Bilibili through our diverse monetization avenues. In addition to live broadcasting and advertising, content creators on Bilibili can earn over one million RMB through the fan charging program, or generate millions of RMB in revenue through premium courses, allowing them to reap the rewards of their creative talent. The welcoming and friendly community atmosphere is an important reason why many users and content creators choose Bilibili. We employ an intelligent self-regulating system to screen and manage negative expressions in the community. Additionally, we conduct targeted community action projects to address issues such as cyberbullying and low-quality content. Beginning in 2019, we launched “Youth Mode,”“ Parental Controls,”“ Family Platform” and other optimized anti-addiction functions for minors. In addition, our“Charging Station” program continues to provide an outlet for our users’ emotional expression, and was updated with an emergency intervention function. In response to cyberviolence such as doxing and personal information leakage, we actively collaborate with relevant authorities and take both online and offline measures to combat such behaviors, safeguarding a clean and positive community environment. Meanwhile, we consistently value information security and user privacy. We are the first online video platform to obtain CCRC APP Security Certification in China. We also share our charitable philosophy in various ways, calling on more young users to participate. The Bilibili Charity Platform is one of the Third Batch of Internet Fundraising Information Platforms for Charitable Organizations designated by the Ministry of Civil Affairs. By early March 2024, the platform had launched 76 charitable projects, drawing in more than 800,000 participants and raising more than RMB17 million. Through our Tower Guardians Charity Program, we resourcefully linked e-sports to cultural heritage preservation. By incorporating supportive bullet chats and hosting charity e-sports matches, we have effectively transformed online support into tangible donations. This initiative has offered assistance to the guardians of 600 ancient towers in Shanxi Province, enhancing their working and living conditions. Supporting rural education has always been the focus of our charity efforts. We aim to offer children in the mountains equal opportunities in education, paving the way for brighter futures and fulfilling their dreams. In June last year, we supported construction of the Bilibili Soccer Primary School in Binchuan County, Dali City, Yunnan Province. Bilibili has now supported the construction of six rural primary schools. Utilizing Bilibili’ s distinctive resources, we have teamed up with our amazing content creators to make top-notch video courses for these children, inspiring joy in their learning and daily life. On our 12th anniversary, we established the Bilibili Happy Scholarship, aiming to spread the warmth and joy of our community to children and teachers in rural areas. As of the end of 2023, the scholarship had cumulatively disbursed over RMB1.19 million, providing support for these schools’ extracurricular innovation projects and interest-based clubs. We firmly believe that good content itself carries significant value. Looking forward, we will continue to encourage and support the creation of high-quality content, enabling more creators’ abilities to create excellent content that reaches more users. We believe that good content plays an indispensable role in driving the development of the internet content industry. At the same time, we will relentlessly uphold stringent ESG standards, fortify our corporate governance and embrace our corporate social responsibility. Let us forge ahead together, steadfast in our commitment to propel society toward sustainable development. Rui Chen Chairman and CEO

Responsible governance The Board of Directors, as the highest decision-making body of Bilibili, possesses a high degree of independence and professionalism, providing accurate and authoritative guidance at various stages of Bilibili’ s development. The Board oversees the Audit Committee, Compensation Committee, and Nomination and Corporate Governance Committee,61 further strengthening the scope and transparency of governance. 62 Bilibili continues to improve its comprehensive, collaborative and agile risk management framework, emphasizing company-wide participation, ensuring flexible response to internal and external risks, and protecting the rights and interests of all stakeholders.

We work closely with independent third-party audit firms and conduct external audits every year to ensure all business lines are properly audited. Meanwhile, based on factors such as business size, strategic development priorities, and level of system dependence, we also identify all internal risks and produce the Special Risk List, which is submitted to leaders of the relevant business teams. Special audits are followed by regular tracking of improvement measures for closed-loop risk resolution.

We have also stepped up management of external suppliers to ensure high ethical standards for all business activities. In 2023, we continued to identify and inspect company-wide business ethics risks, with particular focus on new business activities, to ensure 100% coverage of all business lines. Refining the Internal System Bilibili has established a business ethics system centered around the Bilibili Code of Business Conduct and Ethics, clearly defining management measures regarding anti-corruption, intellectual property protection, anti-discrimination and harassment, and fair trading. We also regulate employee conduct through a series of internal policies such as the Anti-Corruption Compliance Policy, Anti-Fraud and Supervision System and Policy Statement on Material Non-Public Information and Prevention of Insider Trading, among others. In 2023, we issued the policy document Management Measures for Business Entertainment Expenses, which comprehensively defines the protocol for entertainment spending and gifting. Additionally, our Self-Discipline Committee, in collaboration with our Merchandise team, revised and issued the Bilibili Merchandise Integrity Code of Conduct (2.0 version) to further refine the requirements for integrity in our IP derivative and others business. To provide easy access to the integrity policy and code of conduct for employees, we launched an“Integrity System” mini-program on our WeChat Work APP to enhance employee awareness and understanding of our anti-corruption compliance policies. Strengthening Internal Awareness In 2023, we organized a series of business ethics training sessions for all employees (including part-time staff, contractors, interns, etc.), as well as targeted training for board members. For business scenarios involving external engagements and procurement, we hosted targeted policy sessions to introduce real-life case studies that help improve employees’ ability to identify red lines, and tested training outcomes with exams. To help new employees understand our policies, we incorporated business ethics into their mandatory orientation courses. Standardizing External Management We have imposed clear constraints on supplier conduct to ensure business ethics in accordance with our Supplier Management Policy. We require all suppliers to sign our Business Ethics Commitment before being granted access, while also using third-party preset tools we developed in the procurement system to effectively minimize the impact of potential violations by external parties. To further implement the Bilibili Code of Business Conduct and Ethics and prevent violations, we have established a variety of reporting mechanisms. We take whistleblower protection seriously and provide safe and easy-to-use channels for employees and stakeholders. We also conduct timely, transparent and fair investigations for any alleged violation and implement corrective and improvement measures upon resolution.
