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, loss/gain on fair value change in investments in publicly traded companies, gain on repurchase of convertible senior notes, expenses related to organizational optimization, and termination expenses of certain game projects. 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. 2023 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 statements 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, 2022 2023 RMB RMB (in thousands) Net loss (4,294,577) (2,177,777) Add: Share-based compensation expenses 534,560 561,548 Amortization expense related to intangible assets acquired through business acquisitions 96,335 96,302 Income tax related to intangible assets acquired through business acquisitions (18,009) (11,250) Loss/(gain) on fair value change in investments in publicly    traded companies 335,929 (181,233) Gain on repurchase of convertible senior notes (475,790) (282,442) Expenses related to organizational optimization 89,650 — Termination expenses of certain game projects 109,054 — Adjusted net loss (3,622,848) (1,994,852)    4

Mobile Games Services Our revenues from mobile games services were RMB2.0 billion in the first half of this year, representing a decrease of 16% from the first half of 2022, mainly due to the lack of new game launches and revenue declines from certain games.

The change was primarily attributable to a gain of RMB181.2 million on fair value change in investments in publicly traded companies for the six months ended June 30, 2023, compared to a loss of RMB335.9 million on fair value change in investments in publicly traded companies for the same period of 2022. INCOME TAX Income tax expense was RMB55.6 million for the six months ended June 30, 2023, compared with RMB56.6 million for the six months ended June 30, 2022. NET LOSS Net loss was RMB2.2 billion for the six months ended June 30, 2023, narrowing by 49% from RMB4.3 billion for the six months ended June 30, 2022. LIQUIDITY Our cash and cash equivalents, time deposits and short-term investments decreased by 27% from RMB19.6 billion as of December 31, 2022 to RMB14.3 billion as of June 30, 2023. The decrease was primarily due to the repurchase of 2027 Notes for a total cash consideration of US$745.9 million (RMB5.3 billion) during 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, 2023. 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, 2023. PLEDGE OF ASSETS As at June 30, 2023, none of our assets were pledged to secure loans and banking facilities. 14

Bilibili Inc. 2023 Interim Report Management Discussion and Analysis GEARING RATIO As at June 30, 2023, the Company_s gearing ratio (i.e. total liabilities divided by total assets, in percentage) was 52.6%, compared with 63.6% as at December 31, 2022. FUTURE PLANS FOR MATERIAL INVESTMENTS OR CAPITAL ASSETS As at June 30, 2023, 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, 2023. EMPLOYEES AND REMUNERATION As of June 30, 2023, we had a total of 10,354 employees, compared to 11,092 as of December 31, 2022. 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.    15

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 at June 30, 2023, the WVR Beneficiaries were interested in a total of 83,715,114 Class Y Ordinary Shares, representing a total of 71.9% voting rights in the Company with respect to Shareholders_ resolutions relating to matters other than the Reserved Matters (excluding 4,169,372 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 20.4% of the issued share capital of the Company as of June 30, 2023 (excluding 4,169,372 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 at June 30, 2023, 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, and 1,902,000 Class Z Ordinary Shares issuable to Mr. Rui Chen upon exercise of options within 60 days after June 30, 2023, representing 42.4% 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 at June 30, 2023, 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, and 668,000 Class Z Ordinary Shares issuable to Ms. Ni Li upon exercise of options within 60 days after June 30, 2023, representing a total of 6.3% 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 at June 30, 2023, 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 23.4% 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. 16

Bilibili Inc. 2023 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: 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; 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; 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 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 14 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.    During the Reporting Period, we have complied with all the code provisions of the Corporate Governance Code set forth in Part 2 of Appendix 14 to the Listing Rules, save for the following. Code provision C.2.1 of the Corporate Governance Code, recommends, but does not require, that the roles of chairperson 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 chairperson 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. 17

Bilibili Inc. 2023 Interim Report Corporate Governance 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 non-executive 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 FOR SECURITIES TRANSACTIONS BY DIRECTORS The Company has adopted the Code, with terms no less exacting than that of the Model Code for Securities Transactions by Directors of Listed Issuers as set out in Appendix 10 to the Listing Rules, 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 Latest Practicable Date.

Bilibili Inc. 2023 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 33 to 76, which comprises the interim condensed consolidated balance sheet of Bilibili Inc. (the _Company_) and its subsidiaries, variable interest entities (_VIEs_) and subsidiaries of the VIEs (together, the _Group_) as at 30 June 2023 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. 31

Bilibili Inc. 2023 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information 1. OPERATIONS (Continued) Liquidity The Group incurred net losses of RMB4,294.6 million and RMB2,177.8 million for the six months ended June 30, 2022 and 2023, respectively. Net cash used in operating activities was RMB2,104.5 million and RMB651.2 million for the six months ended June 30, 2022 and 2023, respectively. Accumulated deficit was RMB21,479.9 million and RMB23,654.3 million as of December 31, 2022 and June 30, 2023, 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 statements. The Group_s unaudited interim condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. 48

Bilibili Inc. 2023 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information SIGNIFICANT ACCOUNTING POLICIES Basis of presentation The accompanying unaudited interim condensed consolidated financial statements 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 HKEx, as amended, supplemented or otherwise modified from time to time (the “HK Listing Rules”). The December 31, 2022 balance sheet data was derived from audited consolidated financial statements; 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 statements for the preceding fiscal year. The accounting policies applied are consistent with those of the audited consolidated financial statements for the preceding fiscal year. Principles of consolidation The unaudited interim condensed consolidated financial statements include the financial statements 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. 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. 49

Bilibili Inc. 2023 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information SIGNIFICANT ACCOUNTING POLICIES (Continued) Use of estimates The preparation of the Group’s unaudited interim condensed consolidated financial statements 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 statements 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. 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 statements, 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. 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, 2023 are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB7.2513, representing the noon buying rate in The City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York on June 30, 2023. No representation is made that the RMB amounts represent or could have been, or could be, converted, realized or settled into US$ at that rate on June 30, 2023, or at any other rate. 50

Bilibili Inc. 2023 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information SIGNIFICANT ACCOUNTING POLICIES (Continued) 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 RMB2,284.0 million and RMB2,397.8 million for the six months ended June 30, 2022 and 2023, 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, 2022 and 2023. 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 December 31, 2022 and June 30, 2023: December 31, June 30, 2022 2023 RMB in thousands Beginning balance 292,473 305,535 Provisions 130,549 —Write-offs (117,487) (19,727) Ending balance 305,535 285,808    51

Bilibili Inc. 2023 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information CONCENTRATIONS AND RISKS 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, 2022 and 2023 was as follows: For the Six Months Ended June 30, 2022 2023 Total number of telecommunications service providers 119 104 Number of service providers providing 10% or more of the Group’s servers and bandwidth expenditure 3 2 Total percentage of the Group’s servers and bandwidth expenditure provided by 10% or greater service providers 49% 24% 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. 52

Bilibili Inc. 2023 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information CONCENTRATIONS AND RISKS (Continued) 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 (recorded in the short-term investments) 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 and other financial institutions. As of December 31, 2022 and June 30, 2023, substantially all of the Group’s cash and cash equivalents, restricted cash and time deposits were held in major financial institutions 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 mobile game services (mainly relates to remittances due from payment channels and distribution channels) and advertising services. There was no individual payment channel that had receivable balance exceeding 10% of the Group’s accounts receivable balance as of December 31, 2022 and June 30, 2023. There was no distribution channel that had receivable balance exceeding 10% of the Group’s accounts receivable balance as of December 31, 2022. One distribution channel had receivable balance exceeding 10% of the Group’s accounts receivable balance as of June 30, 2023. December 31, June 30, RMB in thousands 2022 2023 Distribution channel A N/A 210,496    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, 2022 and 2023, 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, 2022 and 2023, respectively. 53

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 (loss)/income, net (including impairments)_ equal to the difference between the carrying value and fair value.

Bilibili Inc. 2023 Interim Report Notes to Unaudited Interim Condensed Consolidated Financial Information RECONCILIATION BETWEEN U.S. GAAP AND INTERNATIONAL FINANCIAL REPORTING STANDARDS (Continued) Notes: 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. 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. 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. 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. 76
