The Company believes that the non-GAAP financial measures help identify underlying trends in its business by excluding the impact of share-based compensation expenses, amortization expense related to intangible assets acquired through business acquisitions, income tax related to intangible assets acquired through business acquisitions, gain/loss on fair value change in investments in publicly traded companies, and gain/loss on repurchase of convertible senior notes. The Company believes that the non-GAAP financial measures provide useful information about the Company’s results of operations, enhance the overall understanding of the Company’s past performance and future prospects and allow for greater visibility with respect to key metrics used by the Company’s management in its financial and operational decision-making. 3

Bilibili Inc. 2024 Interim Report Financial Highlights The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP and therefore may not be comparable to similar measures presented by other companies. The non-GAAP financial measures have limitations as analytical tools, and when assessing the Company’s operating performance, cash flows or liquidity, investors should not consider them in isolation, or as a substitute for net loss, cash flows provided by operating activities or other consolidated statement of operations and cash flows data prepared in accordance with U.S. GAAP. The Company mitigates these limitations by reconciling the non-GAAP financial measures to the most comparable U.S. GAAP performance measures, all of which should be considered when evaluating the Company’s performance. The following table sets forth unaudited reconciliation of GAAP and non-GAAP results for the periods indicated. For the Six Months Ended June 30, 2023 2024 RMB RMB (in thousands) Loss from operations (2,652,344) (1,403,731) Add: Share-based compensation expenses 561,548 524,065 Amortization expense related to intangible assets acquired through business acquisitions 96,302 83,552 Adjusted loss from operations (1,994,494) (796,114) Net loss (2,177,777) (1,372,780) Add: Share-based compensation expenses 561,548 524,065 Amortization expense related to intangible assets acquired through business acquisitions 96,302 83,552 Income tax related to intangible assets acquired through business acquisitions (11,250) (10,814) (Gain)/loss on fair value change in investments in publicly traded companies (181,233) 28,125 (Gain)/loss on repurchase of convertible senior notes (282,442) 20,980 Adjusted net loss (1,994,852) (726,872) Net loss attributable to noncontrolling interests 3,384 15,535 Adjusted net loss attributable to the Bilibili Inc.’s shareholders (1,991,468) (711,337) 4 

Bilibili Inc. 2024 Interim Report Business Review and Outlook In the first half of the year, we made solid progress in financial performance and community development. We successfully accelerated revenue growth, improved margins and considerably narrowed losses, all while cultivating a vibrant community with continued user growth and strong engagement metrics. In the first half of this year, we further enhanced our commercialization efficiency and effectively unlocked the value of our community. Our total net revenues were RMB11.79 billion, representing an increase of 14% year over year. Notably, our advertising and VAS revenues increased by 30% and 14% year over year, respectively, showing our effective execution in converting our high-quality user traffic to topline growth. Moreover, our mobile game revenues resumed year-over-year growth in the second quarter, led by the excellent performance of our recently launched new games, including our first strategy game, San Guo: Mou Ding Tian Xia (“San Mou”), which attracted millions of players and showcased our operational capabilities beyond ACG. With accelerated revenue growth and our continued efficient operations, we achieved a notable 47% year-over-year increase in our gross profit in the first half of the year, and our gross profit margin rose to 29.2%, compared with 22.5% of the same period last year. As a result, we meaningfully narrowed our adjusted loss from operations and adjusted net loss by 60% and 64% year over year, respectively. Furthermore, in the first half of the year, we generated a record RMB2.39 billion in operating cash flow, compared with negative RMB651.2 million in the same period last year. These solid achievements have brought us on the right track towards profitability and paved the way for sustainable growth thereafter. While focusing on improving our commercialization capabilities, we continued to attract more users and develop our community with great vitality. In the first half of the year, our DAUs reached over 102.3 million, and our MAUs averaged 338.6 million, representing an 8% and 6% year-over-year increase from the same period last year, respectively. Our users continued to appreciate our diverse and ever-evolving content, with the average daily time spent per active user reaching 102 minutes in the first half of the year, compared to 95 minutes in the same period last year. Content Our self-sustained content ecosystem remains the key foundation for both community traffic growth and commercialization potential. In the first half of the year, we continued to cultivate a thriving community that enables more high-quality content creators to showcase their talent and gain recognition from like-minded users. This strategy has proven to be beneficial. Our average daily video views increased by 20% year over year to over 4.90 billion in the first half of the year. The video views in our leading content categories, including games, entertainment, tech and knowledge, continued to show solid growth. Notably, we have emerged as the go-to platform for AI-related content and discussion in China, as we host the most curious minds in our community. Meanwhile, as our users’ interests expand with each life stage and their purchasing power increases, our diverse content continues to evolve with our users to meet them at every pass. In the first half of the year, video views across consumption-related categories, such as baby and maternity, automotive, travel, fashion and home decoration & appliance, all grew rapidly. 5

Bilibili Inc. 2024 Interim Report Business Review and Outlook We remained dedicated to providing diverse and effective monetization channels to incentivize our content creators. In the first half of this year, approximately 2.1 million content creators earned income on our platform. Our advanced ad products and innovative VAS products both enabled content creators to better monetize their unique talents. In the first half of 2024, content creators’ total income earned through our advertising and VAS products increased by 30% year over year. Community Our inspiring community atmosphere and interactive features have continuously deepened the connection between our users and our platform. Our community remained highly engaged, with an average daily time spent on our platform of 102 minutes in the first half of the year, compared with 95 minutes in the same period last year. Users’ average monthly interactions reached approximately 16.46 billion in the first half of the year, representing a 13% year-on-year increase. Our official member base grew to 243.1 million, rising 13% year on year as of the end of June 2024, with a strong 12-month retention rate remaining at around 80%. Moreover, this July, our signature offline events, Bilibili World and Bilibili Macro Link, once again brought our community together in Shanghai. More than 250,000 people traveled across the country to participate in the events, showing our unparalleled influence among the young generation, as well as users’ strong willingness to pay for our unique community experiences. Commercialization Our initiatives in enhancing the commercial and operational efficiency have yielded encouraging results in the first half of this year. We accelerated topline growth while also improving revenue quality. Based largely on our revenue growth and platform efficiency, we successfully expanded our gross profit margin and significantly narrowed our losses. Value-Added Services Revenues from our VAS business increased by 14% year over year to RMB5.09 billion in the first half of 2024. We continued to add more live broadcasting content offerings, reinforcing the synergies between our live broadcasting and video ecosystem to better cater to users’ diverse interests. Moreover, through refined operational methods, we improved our live broadcasting gross profit margin while increasing the supply of high-quality live broadcasting content. In addition to live broadcasting, we further explored opportunities in our VAS businesses as our generation Z+ users have demonstrated an increasing willingness to pay directly for the content they love. As of the end of June 2024, our premium members exceeded 22.3 million, increasing by 9% year over year. Over 80% of them were annual subscribers or under auto-renewal packages, showing their continued loyalty and trust in Bilibili. Users are also showing a growing tendency to spend on our other VAS products, including our premium online courses, fan charging programs and avatar decorations. We expect these products to open more monetization potential in the future across our massive PUGV content universe. 6

Bilibili Inc. 2024 Interim Report Business Review and Outlook Advertising As our users’ disposable income rises, their commercial value becomes more apparent as they engage with more consumption-related content on Bilibili. Our advertising strategy of aligning advertisers with the appropriate audience to capitalize on these growing trends has proven to be effective. In the first half of the year, revenues from our advertising business were RMB3.71 billion, representing 30% year-over-year growth. Our performance-based ads were a standout contributor to our robust revenue growth. Revenues from our brand advertising and Sparkle advertising offerings also achieved decent growth in the first half of 2024. We are allocating more resources to integrate ad products seamlessly within our content ecosystem. In the first half of 2024, we further improved our ad products and infrastructure to increase our ad efficiency by optimizing our ad-matching algorithms, upgrading our ad placement system, enabling more creative ad formats, and providing visualized data analysis tools for advertisers. In addition, our video and live commerce ad products with direct sales conversion tools continued to yield results. These transaction-based ads enable advertisers to effectively convert users from product viewing to making purchases. Industry-wise, our top five advertising verticals in the first half of the year were games, e-commerce, digital products & home appliances, automotive, and food and beverages. We continued to gain more market shares in our anchor verticals, such as games and e-commerce. In addition, revenues from emerging verticals, such as internet services, AI and education, also saw meaningful increases in the first half of the year, showing our potential to replicate the success in our leading verticals to more advertisers from various industries. In the first half of 2024, the number of advertisers on our platform increased by over 50% year over year. Mobile Games Services Revenues from our mobile games business totaled RMB1.99 billion in the first half of the year, reflecting a decrease of 2% year over year. Our two evergreen titles, Fate Grand Order and Azur Lane, made relatively stable contributions to our game revenues in the first half of the year and entered into their eighth and seventh year of operation, demonstrating these games’ remarkable longevity. In the first half of this year, we successfully launched two new games, including an ACG title Articrafter and our first strategy game, San Mou, both of which are well received by game lovers. Particularly for San Mou, it ranked No. 3 on the iOS game grossing chart on the first day of its launch, attracting millions of gamers to the three kingdoms’ battlefields. Given the sizable strategy game market, this game’s promising start and the inherent longevity of strategy games, we are confident San Mou will become one of our flagship games with lasting appeal. More importantly, as our community and gamer base have both expanded exponentially since our founding, San Mou’s success represents a significant milestone in our game genre diversification strategy and underscores the vast potential of our game portfolio. We will continue to leverage our position as a leading game community and seize opportunities to reinvent games for the new generation of gamers. 7

Bilibili Inc. 2024 Interim Report Business Review and Outlook Repurchase of Convertible Senior Notes In March 2024, the Company completed the repurchase right offer for its 1.375% Convertible Senior Notes due 2026 (“April 2026 Notes”). An aggregate principal amount of US$429.3 million (RMB3.05 billion) April 2026 Notes was validly surrendered and repurchased with an aggregate cash consideration of US$429.3 million (RMB3.05 billion). As of June 30, 2024, the aggregate outstanding principal amount of April 2026 Notes, 2027 Notes and December 2026 Notes was US$432.5 million (RMB3.08 billion). RECENT DEVELOPMENTS AFTER THE REPORTING PERIOD Save as disclosed in this interim report, there were no other significant events that might affect us since the end of the Reporting Period and up to the Latest Practicable Date. BUSINESS OUTLOOK In the first half of the year, our accelerated monetization efforts yielded promising results, including accelerated revenue growth, meaningful margin improvement and considerable loss reduction, all while cultivating a vibrant community. Moving into the second half of the year, we will further invest in enhancing our commercialization capabilities to unlock the value of our users and community. We believe that, by strengthening our ad infrastructure, we will better meet users’ evolving consumption needs; by integrating various VAS products with our ecosystem, we will unlock more monetization potential of our vast content library; and by reinventing strategy games to appeal to younger audiences, we can capture additional game revenue. With the improvement in our financial performances, we remain committed to our core mission: building a stage for content creators to shine, fostering a healthy, vibrant community for users to enjoy, and bringing value to our shareholders and partners over the long term. 8

Bilibili Inc. 2024 Interim Report Management Discussion and Analysis NET REVENUES Total net revenues were RMB11.79 billion for the six months ended June 30, 2024, representing an increase of 14% from RMB10.37 billion for the six months ended June 30, 2023. Value-added services (VAS) Revenues from VAS were RMB5.09 billion for the six months ended June 30, 2024, representing an increase of 14% from RMB4.46 billion for the six months ended June 30, 2023. The increase was led by increases in revenues from live broadcasting, premium membership, and other value-added services. Advertising Revenues from advertising were RMB3.71 billion for the six months ended June 30, 2024, representing an increase of 30% from RMB2.84 billion for the six months ended June 30, 2023. This increase was mainly attributable to the Company’s improved advertising product offerings and enhanced advertising efficiency. Mobile games Revenues from mobile games were RMB1.99 billion for the six months ended June 30, 2024, representing a decrease of 2% from RMB2.02 billion for the six months ended June 30, 2023. The decrease was mainly due to lower revenues from certain existing games and was mostly offset by the increased revenues from the launch of the Company’s exclusively licensed games in the second quarter of 2024. IP derivatives and others Revenues from IP derivatives and others were RMB1.00 billion for the six months ended June 30, 2024, representing a decrease of 5% from RMB1.05 billion for the six months ended June 30, 2023. COST OF REVENUES Cost of revenues was RMB8.35 billion for the six months ended June 30, 2024, representing an increase of 4% from RMB8.04 billion for the six months ended June 30, 2023. The increase was mainly due to higher revenue-sharing costs and was partially offset by lower content costs, staff costs and other costs. Revenue-sharing costs, a key component of cost of revenues, was RMB4.72 billion, representing an increase of 12% from RMB4.22 billion for the six months ended June 30, 2023. GROSS PROFIT Gross profit was RMB3.44 billion for the six months ended June 30, 2024, representing an increase of 47% from RMB2.33 billion for the six months ended June 30, 2023, primarily due to growth in total net revenues and relatively stable costs related to platform operations. 10

Bilibili Inc. 2024 Interim Report Management Discussion and Analysis OPERATING EXPENSES Total operating expenses were RMB4.84 billion for the six months ended June 30, 2024, representing a decrease of 3% from RMB4.98 billion for the six months ended June 30, 2023. Sales and marketing expenses Sales and marketing expenses were RMB1.96 billion for the six months ended June 30, 2024, representing a 9% increase from RMB1.80 billion for the six months ended June 30, 2023. The increase was primarily attributable to increased marketing expenses for new game launches. General and administrative expenses General and administrative expenses were RMB1.02 billion for the six months ended June 30, 2024, representing an 8% decrease from RMB1.11 billion for the six months ended June 30, 2023. The decrease was primary attributable to a decrease in the headcount of general and administrative personnel and lower rental-related expenses. Research and development expenses Research and development expenses were RMB1.86 billion for the six months ended June 30, 2024, representing a 10% decrease from RMB2.07 billion for the six months ended June 30, 2023. The decrease was mainly attributable to a decrease in the headcount of research and development personnel. LOSS FROM OPERATIONS Loss from operations was RMB1.40 billion for the six months ended June 30, 2024, narrowing by 47% from RMB2.65 billion for the six months ended June 30, 2023. ADJUSTED LOSS FROM OPERATIONS Adjusted loss from operations was RMB796.1 million for the six months ended June 30, 2024, narrowing by 60% from RMB1.99 billion for the six months ended June 30, 2023. TOTAL OTHER INCOME, NET Total other income was RMB26.4 million for the six months ended June 30, 2024, compared with total other income of RMB530.2 million in the same period of 2023. The change was primarily attributable to a loss of RMB28.1 million on fair value change in investments in publicly traded companies and a loss of RMB21.0 million from the repurchase of convertible senior notes for the six months ended June 30, 2024, compared to a gain of RMB181.2 million on fair value change in investments in publicly traded companies and a gain of RMB282.4 million from the repurchase of convertible senior notes for the six months ended June 30, 2023. 11

Bilibili Inc. 2024 Interim Report Management Discussion and Analysis INCOME TAX (EXPENSE)/BENEFIT Income tax benefit was RMB4.6 million for the six months ended June 30, 2024, compared with income tax expense of RMB55.6 million for the six months ended June 30, 2023. NET LOSS Net loss was RMB1.37 billion for the six months ended June 30, 2024, narrowing by 37% from RMB2.18 billion for the six months ended June 30, 2023. ADJUSTED NET LOSS Adjusted net loss was RMB726.9 million for the six months ended June 30, 2024, narrowing by 64% from RMB1.99 billion for the six months ended June 30, 2023. LIQUIDITY The Company had cash and cash equivalents, time deposits and short-term investments of RMB13.91 billion as of June 30, 2024, compared with RMB15.04 billion as of December 31, 2023. The decrease was mainly due to the repurchase of April 2026 Notes for a total cash consideration of US$429.3 million (RMB3.05 billion) for the six months ended June 30, 2024, partially offset by operating cash flow generated for the six months ended June 30, 2024. The Company generated RMB2.39 billion operating cash flow for the six months ended June 30, 2024, compared with negative RMB651.2 million operating cash flow for the six months ended June 30, 2023. SIGNIFICANT INVESTMENTS The Group did not make or hold any significant investments during the six months ended June 30, 2024. MATERIAL ACQUISITIONS AND DISPOSALS The Group did not have any material acquisitions or disposals of subsidiaries, consolidated affiliated entities or associated companies during the six months ended June 30, 2024. PLEDGE OF ASSETS As at June 30, 2024, none of our assets were pledged to secure loans and banking facilities. 12

Bilibili Inc. 2024 Interim Report Management Discussion and Analysis GEARING RATIO As at June 30, 2024, the Company’s gearing ratio (i.e. total liabilities divided by total assets, in percentage) was 56.6%, compared with 56.6% as at December 31, 2023. FUTURE PLANS FOR MATERIAL INVESTMENTS OR CAPITAL ASSETS As at June 30, 2024, the Group did not have detailed future plans for material investments or capital assets. FOREIGN EXCHANGE EXPOSURE A substantial majority of our revenues and costs is denominated in Renminbi. Any significant depreciation of the Renminbi may materially adversely affect the value of, and any dividends payable on, the ADSs in U.S. dollars. For example, when we convert our U.S. dollars denominated funds into Renminbi for our operations, appreciation of the Renminbi against the U.S. dollar would have an adverse effect on the Renminbi amount we would receive from the conversion. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us. In addition, appreciation or depreciation in the value of the Renminbi relative to U.S. dollars would affect our financial results reported in U.S. dollar terms regardless of any underlying change in our business or results of operations. Very limited hedging options are available in China to reduce our exposure to exchange rate fluctuations. To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedge our exposure or at all. In addition, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert Renminbi into foreign currency. CONTINGENT LIABILITIES The Company had no material contingent liabilities as at June 30, 2024. EMPLOYEES AND REMUNERATION As of June 30, 2024, the Company had a total of 8,137 employees, compared to 8,801 as of December 31, 2023. As required under PRC regulations, the Company participates in housing funds and various employee social security plans that are organized by applicable local municipal and provincial governments, including housing funds, pension, maternity, medical, work-related injury and unemployment benefit plans, under which we make contributions at specified percentages of the salaries of its employees. We also purchase commercial health and accidental insurance for our employees. Bonuses are generally discretionary and based in part on employee performance and in part on the overall performance of the Group’s business. The Company has granted and plans to continue to grant share-based incentive awards to its employees in the future to incentivize their contributions to its growth and development. 13

The Company’s weighted voting rights structure enables Mr. Rui Chen, Ms. Ni Li and Mr. Yi Xu, holders of the Class Y Ordinary Shares (the “WVR Beneficiaries”), to exercise voting control over the Company notwithstanding that the WVR Beneficiaries do not hold a majority economic interest in the share capital of the Company. This allows the Company to benefit from the continued vision and leadership of the WVR Beneficiaries. Shareholders and prospective investors are advised to be aware of the potential risks of investing in companies with a weighted voting rights structure, in particular that the interests of the WVR Beneficiaries may not necessarily always be aligned with those of our Shareholders as a whole, and that the WVR Beneficiaries will be in a position to exert significant influence over the affairs of the Company and the outcome of Shareholders’ resolutions, irrespective of how other Shareholders vote. Prospective investors should make the decision to invest in the Company only after due and careful consideration. As of June 30, 2024, the WVR Beneficiaries were interested in a total of 83,715,114 Class Y Ordinary Shares, representing a total of 71.7% voting rights in the Company with respect to Shareholders’ resolutions relating to matters other than the Reserved Matters (excluding 7,126,386 Class Z Ordinary Shares issued and reserved for future issuance upon the exercise or vesting of awards granted under the Company’s share incentive plans). Class Y Ordinary Shares may be converted into Class Z Ordinary Shares on a one-to-one ratio. Upon the conversion of the Class Y Ordinary Shares, the Company would redesignate 83,715,114 Class Y Ordinary Shares and reissue the same number of Class Z Ordinary Shares, representing 20.2% of the issued share capital of the Company as of June 30, 2024 (excluding 7,126,386 Class Z Ordinary Shares issued and reserved for future issuance upon the exercise or vesting of awards granted under the Company’s share incentive plans). As of June 30, 2024, Mr. Rui Chen was interested in, and controlled through Vanship Limited, 49,299,006 Class Y Ordinary Shares and 525,525 Class Z Ordinary Shares in the form of ADSs, representing 42.3% of the voting rights in the Company. Vanship Limited is controlled by a trust of which Mr. Chen and his family members are the beneficiaries. As of June 30, 2024, Ms. Ni Li was interested in, and controlled through Saber Lily Limited, 7,200,000 Class Y Ordinary Shares and 908,300 Class Z Ordinary Shares, representing a total of 6.2% of the voting rights in the Company. Saber Lily Limited is controlled by a trust, and Ms. Li and her family members are the trust’s beneficiaries. As of June 30, 2024, Mr. Yi Xu was interested in, and controlled through Kami Sama Limited, 27,216,108 Class Y Ordinary Shares and 151,100 Class Z Ordinary Shares, and he held 45,000 Class Z Ordinary Shares in the form of ADSs, representing a total of 23.3% of the voting rights in the Company. Kami Sama Limited is controlled by a trust, and Mr. Xu and his family members are the trust’s beneficiaries. 14

Bilibili Inc. 2024 Interim Report Corporate Governance The weighted voting rights attached to the Class Y Ordinary Shares will cease when none of the WVR Beneficiaries have beneficial ownership of any of the Class Y Ordinary Shares, in accordance with Rule 8A.22 of the Listing Rules. This may occur: (i) upon the occurrence of any of the circumstances set out in Rule 8A.17 of the Listing Rules, in particular where a WVR Beneficiary is: (1) deceased; (2) no longer a member of our Board; (3) deemed by the Stock Exchange to be incapacitated for the purpose of performing his duties as a director; or (4) deemed by the Stock Exchange to no longer meet the requirements of a director set out in the Listing Rules; (ii) when a WVR Beneficiary has transferred to another person the beneficial ownership of, or economic interest in, all of the Class Y Ordinary Shares or the voting rights attached to them, other than in the circumstances permitted by Rule 8A.18 of the Listing Rules; (iii) where a vehicle holding Class Y Ordinary Shares on behalf of a WVR Beneficiary no longer complies with Rule 8A.18(2) of the Listing Rules; or (iv) when all of the Class Y Ordinary Shares have been converted to Class Z Ordinary Shares. The Company confirms that it has, during the Reporting Period, complied with the Corporate Governance Code set out in Appendix C1 to the Listing Rules to the extent required by Chapter 8A of the Listing Rules. COMPLIANCE WITH THE CORPORATE GOVERNANCE CODE The Board is committed to achieving high corporate governance standards. The Board believes that high corporate governance standards are essential in providing a framework for the Company to safeguard the interests of shareholders and to enhance corporate value and accountability. The Company’s voluntary conversion of its secondary listing status to primary listing on the Main Board of the Stock Exchange became effective on October 3, 2022, since which the Corporate Governance Code has been applicable to the Company. 15

Bilibili Inc. 2024 Interim Report Corporate Governance During the Reporting Period, we have complied with all of the applicable code provisions of the Corporate Governance Code, save for the following: Code provision C.2.1 of the Corporate Governance Code, recommends, but does not require, that the roles of chairman and chief executive officer should be separate and should not be performed by the same person. The Company deviates from this code provision because Mr. Rui Chen performs both the roles of the chairman of the Board and the chief executive officer of the Company. Mr. Chen has extensive experience in our business operations and management. The Board believes that vesting the roles of both chairman and chief executive officer to Mr. Chen has the benefit of ensuring consistent leadership within the Company and enables more effective and efficient overall strategic planning. This structure will enable the Company to make and implement decisions promptly and effectively. The Board considers that the balance of power and authority will not be impaired due to this arrangement. In addition, all major decisions are made in consultation with members of the Board, including the relevant Board committees, and four independent Directors. The Board will reassess the division of the roles of chairman and the chief executive officer from time to time, and may recommend dividing the two roles between different people in the future, taking into account our circumstances as a whole. Code provision F.1.1 of the Corporate Governance Code provides that an issuer should have a policy on payment of dividends and should disclose it in the annual report. The Company deviates from this code provision because the Company does not have a dividend policy. The Board has complete discretion on whether to distribute dividends, subject to certain requirements of Cayman Islands law. Even if the Board decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that the board of directors may deem relevant. We do not have any present plan to pay any cash dividends on our ordinary shares in the foreseeable future. We currently intend to retain most, if not all, of our available funds and any future earnings to operate and expand our business. COMPLIANCE WITH THE MODEL CODE The Company has adopted the Code with terms no less exacting than that of the Model Code, as its own securities dealing code to regulate all dealings by Directors and relevant employees of securities in the Company and other matters covered by the Code. Specific enquiry has been made of all the Directors and the relevant employees and they have confirmed that they have complied with the Code during the Reporting Period and up to the date of the Latest Practicable Date. 16

Bilibili Inc. 2024 Interim Report Other Information 2018 Share Incentive Plan (amended and restated as the Second Amended and Restated 2018 Share Incentive Plan on June 28, 2024) The maximum aggregate number of Class Z Ordinary Shares which may be issued pursuant to all awards under the 2018 Share Incentive Plan (before its amendment and restatement) is 30,673,710, which is 10% of the total number of issued Class Z Ordinary Shares as at the Primary Conversion Effective Date (excluding Class Z Ordinary Shares underlying awards which have terminated, expired, lapsed or have been forfeited in accordance with the rules of the 2018 Share Incentive Plan). As at January 1, 2024, 19,909,908 Class Z Ordinary Shares were available for grant under the 2018 Share Incentive Plan.

As the 2018 Share Incentive Plan was amended and restated as the Second Amended and Restated Share Incentive Plan at the annual general meeting of the Company on June 28, 2024 (the “Adoption Date”), no further grants may be made under the 2018 Share Incentive Plan thereafter. As disclosed in the circular of the Company dated April 9, 2024, any granted and unexercised options, and any granted and unvested awards under the 2018 Share Incentive Plan prior to the Adoption Date shall continue to be valid and exercisable and/or vested in accordance with the terms of the grant and the 2018 Share Incentive Plan. The maximum aggregate number of Class Z Ordinary Shares which may be issued pursuant to all awards (including options, restricted share and restricted share units) under the Second Amended and Restated 2018 Share Incentive Plan together with the number of Class Z Ordinary Shares which may be issued pursuant to any awards to be granted any other share schemes of the Company (the “Scheme Limit”) is 41,413,503, representing 10% of the total number of issued and outstanding Shares (including both Class Y Ordinary Shares and Class Z Ordinary Shares) as at the Adoption Date. No awards have been granted under the Second Amended and Restated 2018 Share Incentive Plan since its adoption.

Bilibili Inc. 2024 Interim Report Report on Review of Interim Financial Information To the Board of Directors of Bilibili Inc. (incorporated in the Cayman Islands with limited liability) INTRODUCTION We have reviewed the interim financial information set out on pages 32 to 72, which comprises the interim condensed consolidated balance sheet of Bilibili Inc. (the “Company”) and its subsidiaries (together, the “Group”) as at 30 June 2024 and the interim condensed consolidated statement of operations and comprehensive loss, the interim condensed consolidated statement of changes in shareholders’ equity and the interim condensed consolidated statement of cash flows for the six-month period then ended, and notes, comprising significant accounting policies and other explanatory information. The Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited require the preparation of a report on interim financial information to be in compliance with the relevant provisions thereof and accounting principles generally accepted in the United States of America (“U.S. GAAP”). The directors of the Company are responsible for the preparation and presentation of this interim financial information in accordance with U.S. GAAP. Our responsibility is to express a conclusion on this interim financial information based on our review and to report our conclusion solely to you, as a body, in accordance with our agreed terms of engagement, and for no other purpose. We do not assume responsibility towards or accept liability to any other person for the contents of this report. SCOPE OF REVIEW We conducted our review in accordance with International Standard on Review Engagements 2410, “Review of Interim Financial Information Performed by the Independent Auditor of the Entity”. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. CONCLUSION Based on our review, nothing has come to our attention that causes us to believe that the interim financial information of the Group is not prepared, in all material respects, in accordance with U.S. GAAP.

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 1. OPERATIONS Bilibili Inc. (the “Company” or “Bilibili”) is an iconic brand and a leading video community for young generations in China. Incorporated as a limited liability company in the Cayman Islands in December 2013, the Company, through its consolidated subsidiaries, variable interest entities (“VIEs”) and subsidiaries of the VIEs (collectively referred to as the “Group”), is primarily engaged in the operation of providing online entertainment services to users in the People’s Republic of China (the “PRC” or “China”). In April 2018, the Company completed its IPO on the Nasdaq Global Select Market. In March 2021, the Company successfully listed its Class Z ordinary shares on the main board of the Hong Kong Stock Exchange. The Company issued a total 28,750,000 Class Z ordinary shares in the global offering, including the fully exercised over-allotment option of 3,750,000 Class Z ordinary shares. Net proceeds from the global offering, including the over-allotment option, after deducting underwriting fees and other offering expenses, were approximately HKD22.9 billion (RMB19.3 billion). On October 3, 2022, the Company’s voluntary conversion of its secondary listing status to primary listing on the main board of the Hong Kong Stock Exchange became effective. The Company became a dual-primary listed company on the main board of the Hong Kong Stock Exchange in Hong Kong and the Nasdaq in the United States. In January 2023, the Company completed an offering of 15,344,000 ADSs at US$26.65 per ADS. The amount of net proceeds from such offering (after deducting all applicable costs and expenses including but not limited to selling commission) is approximately US$396.9 million (RMB2,689.4 million). Shortly thereafter, the Company completed repurchase of an aggregate principal amount of US$384.8 million of its outstanding 0.50% convertible senior notes due December 2026 with an aggregate purchase price of US$331.2 million (RMB2,243.8 million), which was funded by the net proceeds from the ADS Offering.

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 1. OPERATIONS (Continued) Liquidity The Group incurred net losses of RMB2,177.8 million and RMB1,372.8 million for the six months ended June 30, 2023 and 2024, respectively. Net cash used in operating activities was RMB651.2 million for the six months ended June 30, 2023, and net cash provided by operating activities was RMB2,388.2 million for the six months ended June 30, 2024, respectively. Accumulated deficit was RMB26.31 billion and RMB27.67 billion as of December 31, 2023 and June 30, 2024, respectively. The Group assesses its liquidity by its ability to generate cash from operating activities and attract investors’ investments. Historically, the Group has relied principally on both operational sources of cash and non-operational sources of financing from investors to fund its operations and business development. The Group’s ability to continue as a going concern is dependent on management’s ability to successfully execute its business plan, which includes increasing revenues while controlling operating expenses, as well as, generating operational cash flows and continuing to gain support from outside sources of financing. In the past, the Group has been continuously receiving financing support from outside investors. In January 2023, the Company completed an offering of 15,344,000 American depositary shares (the “ADS Offering”). The amount of net proceeds from the Offering (after deducting all applicable costs and expenses including but not limited to selling commission) is approximately US$396.9 million (RMB2,689.4 million). Shortly thereafter, the Company completed repurchase of an aggregate principal amount of US$384.8 million of its outstanding 0.50% convertible senior notes due December 2026 with the aggregate purchase price of US$331.2 million (RMB2,243.8 million), which was funded by the net proceeds from the ADS Offering. And the remaining net proceeds, after deducting selling commissions of the ADS Offering is US$68.8 million. Moreover, the Group can adjust the pace of its operation expansion and control the operating expenses. Based on the above considerations, the Group believes the cash and cash equivalents and the operating cash flows are sufficient to meet the cash requirements to fund planned operations and other commitments for at least the next twelve months from the date of the issuance of the unaudited interim condensed consolidated financial information. The Group’s unaudited interim condensed consolidated financial information have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. 46

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 2. SIGNIFICANT ACCOUNTING POLICIES a) Basis of presentation The accompanying unaudited interim condensed consolidated financial information and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) applicable to interim financial information and the disclosure requirements of the Rules Governing the Listing of Securities on the Stock Exchange of Hong Kong , as amended, supplemented or otherwise modified from time to time (the “HK Listing Rules”). The December 31, 2023 balance sheet data was derived from audited consolidated financial information; however, the accompanying interim notes to the unaudited interim condensed consolidated financial information do not include all of the annual disclosures required by U.S. GAAP. Results for interim periods are not necessarily indicative of those that may be expected for a full year. The financial information included herein should be read in conjunction with the Company’s audited consolidated financial information for the preceding fiscal year. The accounting policies applied are consistent with those of the audited consolidated financial information for the preceding fiscal year. b) Principles of consolidation The unaudited interim condensed consolidated financial information include the financial statement of the Company, its subsidiaries and VIEs (inclusive of the VIEs’ subsidiaries) for which the Company is the primary beneficiary. Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power, has the power to appoint or remove the majority of the members of the board of directors, or to cast a majority of votes at the meeting of the board of directors, or has the power to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders. A consolidated VIE is an entity in which the Company’s subsidiary, through contractual arrangements, has the power to direct the activities that most significantly impact the entity’s economic performance, bears the risks of and enjoys the rewards normally associated with ownership of the entity, and therefore the Company’s subsidiary is the primary beneficiary of the entity. 47

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 2. SIGNIFICANT ACCOUNTING POLICIES (Continued) b) Principles of consolidation (Continued) All transactions and balances among the Company, its subsidiaries and VIEs (inclusive of the VIEs’ subsidiaries) have been eliminated upon consolidation. There is no VIE in the Group where the Company or any subsidiary has a variable interest but is not the primary beneficiary. c) Use of estimates The preparation of the Group’s unaudited interim condensed consolidated financial information in conformity with the U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the balance sheet date and reported revenues and expenses during the reported periods in the unaudited interim condensed consolidated financial information and accompanying notes. Significant accounting estimates include, but are not limited to, determination of the average playing period for paying players, and assessment for the impairment of long-term investments accounted for using the measurement alternative. d) Functional currency and foreign currency translation The Group uses Renminbi (“RMB”) as its reporting currency. The Company and several of its overseas subsidiaries use US$ or their respective local currencies as their functional currency. The functional currency of the Group’s PRC entities is RMB. In the unaudited interim condensed consolidated financial information, the financial information of the Company and other entities located outside of the PRC have been translated into RMB. Assets and liabilities are translated at the exchange rates on the balance sheet date, equity amounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the period. Translation adjustments are reported as foreign currency translation adjustments, and are shown as a component of other comprehensive income on the unaudited interim condensed consolidated statement of operations and comprehensive loss. Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are translated into the functional currency using the applicable exchange rates at the balance sheet dates. Net gains and losses resulting from foreign exchange transactions are included in “Exchange losses” on the unaudited interim condensed consolidated statement of operations and comprehensive loss. 48

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 2. SIGNIFICANT ACCOUNTING POLICIES (Continued) e) Convenience translation Translations of balances on the unaudited interim condensed consolidated balance sheet, unaudited interim condensed consolidated statement of operations and comprehensive loss and unaudited interim condensed consolidated statement of cash flows from RMB into US$ as of and for the six months ended June 30, 2024 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB7.2672, representing the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York on June 28, 2024. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into US$ at such rate. f) Contract balances Due to the generally short-term duration of the relevant contracts, the majority of the performance obligations are satisfied within one year. The amount of revenue recognized that was included in the receipts in advance balance at the beginning of the period was RMB2,397.8 million and RMB2,523.4 million for the six months ended June 30, 2023 and 2024, respectively. The Group did not have any arrangement where the performance obligations had already been satisfied in the past period but recognized the corresponding revenue in the current period for the six months ended June 30, 2023 and 2024. g) Receivables, net The following table sets out movements of the allowance against accounts receivable, amount due from related parties and other receivables recorded in prepayments and other current assets within the scope of ASC Topic 326 as of June 30, 2023 and 2024, respectively: June 30, June 30, 2023 2024 RMB in thousands Beginning balance 305,535 219,201 Provisions — 68,249 Write-offs (19,727) (51,626) Ending balance 285,808 235,824 49

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 3. CONCENTRATIONS AND RISKS a) Telecommunications service provider The Group relied on telecommunications service providers and their affiliates for servers and bandwidth services to support its operations for the six months ended June 30, 2023 and 2024 was as follows: For the Six Months Ended June 30, 2023 2024 Total number of telecommunications service providers 104 103 Number of service providers providing 10% or more of the Group’s servers and bandwidth expenditure 2 4 Total percentage of the Group’s servers and bandwidth expenditure provided by 10% or greater service providers 24% 53% b) Foreign currency exchange rate risk The functional currency and the reporting currency of the Company are U.S. dollars and RMB, respectively. The Group’s exposure to foreign currency exchange rate risk primarily relates to cash and cash equivalents, time deposits, short-term and long-term investments, and convertible senior notes and accounts payable denominated in the U.S. dollars. Most of the Group’s revenues, costs and expenses are denominated in RMB, while the convertible senior notes and a portion of cash and cash equivalents, time deposits, short-term and long-term investments, and accounts payable are denominated in U.S. dollars. Any significant fluctuation of RMB against U.S. dollars may materially and adversely affect the Company’s cash flows, revenues, earnings and financial positions. 50

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 3. CONCENTRATIONS AND RISKS (Continued) c) Credit risk The Group’s financial instruments potentially subject to significant concentrations of credit risk primarily consist of cash and cash equivalents, restricted cash, time deposits, accounts receivable, and money market funds and financial products (recorded in the short-term and long-term investments) with variable interest rates referenced to performance of underlying assets issued by commercial banks. As of December 31, 2023 and June 30, 2024, substantially all of the Group’s cash and cash equivalents, restricted cash and time deposits were held in major commercial banks located in the United States of America and China, which management consider being of high credit quality. Accounts receivable is typically unsecured and is primarily derived from revenue earned from advertising, VAS and mobile game services (mainly relates to remittances due from payment channels and distribution channels). The following table presents distribution channel and customer that had receivable balance exceeding 10% of the Group’s accounts receivable balance as of December 31, 2023 and June 30, 2024. December 31, June 30, RMB in thousands 2023 2024 Distribution channel A 236,549 387,955 Customer A 235,125 <10% d) Major customers and supplying channels No single customer represented 10% or more of the Group’s net revenues for the six months ended June 30, 2023 and 2024, respectively. The Group relied on a distribution channel to publish and generate the iOS version of its mobile games. There is no single distribution channel of mobile games generated 10% or more of the Group’s net revenues for the six months ended June 30, 2023 and 2024, respectively. e) Mobile games Mobile game revenues accounted for 19% and 17% of the Group’s total net revenues for the six months ended June 30, 2023 and 2024, respectively. No mobile game individually contributed more than 10% of the Group’s total net revenues for the six months ended June 30, 2023 and 2024, respectively. 51

Under this measurement alternative, changes in the carrying value of the equity investments will be recognized in current earning, whenever there are observable price changes in orderly transactions for the identical or similar investment of the same issuer. For those equity investments that the Group elects to use the measurement alternative, the Group makes a qualitative assessment of whether the investment is impaired at each reporting date. If a qualitative assessment indicates that the investment is impaired, the Group has to estimate the investment’s fair value in accordance with the principles of ASC 820. If the fair value is less than the investment’s carrying value, the Group recognizes an impairment loss in “Investment income/(loss), net (including impairments)” equal to the difference between the carrying value and fair value. A loss of RMB75.0 million and nil re-measurement of equity investments accounted for using the measurement alternative was recognized for the six months ended June 30, 2023 and 2024, respectively. The Group recorded impairment charges for long-term investments of RMB69.9 million and RMB100.6 million as “Investment income/(loss), net (including impairments)” for the six months ended June 30, 2023 and 2024, respectively, as the investees’ unsatisfied financial performance with no obvious upturn or potential financing solutions in the foreseeable future, and the Group determined the fair value of these investments was less than their carrying value.

Bilibili Inc. 2024 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 22. RECONCILIATION BETWEEN U.S. GAAP AND INTERNATIONAL FINANCIAL REPORTING STANDARDS (Continued) Notes: (i) Convertible senior notes Under U.S. GAAP, the convertible senior notes were measured at amortized cost, with any difference between the initial carrying value and the repayment amount recognized as interest expenses using the effective interest method over the period from the issuance date to the maturity date. Under IFRS, the Group’s convertible senior notes were designated as financial liabilities at fair value through profit or loss such that the convertible senior notes were initially recognized at fair values. Subsequent to initial recognition, the Group considered that the amounts of changes in fair value of the convertible senior notes that were attributed to changes in credit risk recognized in other comprehensive income, and the rest amounts of changes in fair value of the convertible senior notes were recognized in the profit or loss. (ii) Leases Under U.S. GAAP, the amortization of the right-of-use assets and interest expense related to the lease liabilities are recorded together as lease expense to produce a straight-line recognition effect in the income statement. Under IFRS, the amortization of the right-of-use asset is on a straight-line basis while the interest expense related to the lease liabilities are measured on the basis that the lease liabilities are measured at amortized cost. The amortization of the right-of-use asset is recorded as lease expense and the interest expense is required to be presented in separate line item. (iii) Equity investments using the measurement alternative Under U.S. GAAP, the Group elects to use the measurement alternative to record equity investments without readily determinable fair values at cost, less impairment, and plus or minus subsequent adjustments for observable price changes. Under IFRS, these investments were classified as financial assets at fair value through profit or loss and measured at fair value with changes in fair value recognized through profit or loss. Fair value changes of these investments were recognized in the profit or loss. (iv) Share-based compensation Under U.S. GAAP, for the options and RSUs granted to employees with service condition only, the share- based compensation expenses were recognized over the vesting period using straight-line method. Under IFRS, for the options and RSUs granted to employees with service condition only, the graded vesting method must be applied. 72
