On January 12, 2024, BlackRock entered into a Transaction Agreement (as amended, restated or supplemented from time to time, the "Transaction Agreement") to acquire 100% of the business and assets of Global Infrastructure Management, LLC ("GIP Parent") for a total consideration of $3 billion in cash and approximately 12 million shares of BlackRock common stock (the "GIP Transaction"). Approximately 30% of the total consideration, all in stock, has been deferred and is expected to be issued in approximately five years, subject to the satisfaction of certain post-closing events. The shares of BlackRock common stock were issued in reliance upon the exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended. The GIP Transaction closed on October 1, 2024. Pursuant to the Transaction Agreement, BlackRock acquired the business and assets of GIP Parent by first effecting a merger in accordance with Section 251(g) of the Delaware General Corporation Law. BlackRock merged with a direct wholly owned subsidiary ("Merger Sub") of BlackRock Funding, Inc., a direct wholly owned subsidiary of BlackRock ("BlackRock Funding"), with BlackRock surviving the merger as a direct wholly owned subsidiary of BlackRock Funding (the "BlackRock Merger"). Each share of common stock, $0.01 par value per share, of BlackRock issued and outstanding immediately prior to the closing of the BlackRock Merger (other than shares of common stock held in treasury by BlackRock not held on behalf of a third party, which shares were cancelled) was converted into one share of common stock, $0.01 par value per share, of BlackRock Funding. Following the BlackRock Merger, BlackRock Funding became the publicly listed company with the name "BlackRock, Inc." and acquired all of the issued and outstanding limited liability company interests of GIP Parent. Following the completion of the GIP Transaction, BlackRock was renamed "BlackRock Finance, Inc." and is a wholly owned subsidiary of BlackRock Funding (which has been renamed "BlackRock, Inc."). On January 28, 2025, in connection with an internal reorganization, BPM has been delegated authority to file this Schedule 13D with respect to the 42,760,591 shares of Class A Common Stock and 42,075,949 shares of Class C Common Stock beneficially owned by the GIP Entities as of January 28, 2025. At the time of the internal reorganization, certain of BlackRock's investment adviser subsidiaries (each an "Advisory Subsidiary" and collectively the "Advisory Subsidiaries"), in their capacity as investment advisers to certain client accounts, held beneficial ownership of shares of Class A Common Stock and shares of Class C Common Stock. Such acquisitions were made for investment purposes with available funds of the applicable client accounts in the ordinary course of business of the Advisory Subsidiaries. Following the internal reorganization, BPM has been delegated authority to file this Schedule 13D with respect to the 136,977 shares of Class A Common Stock and 1,678,725 Class C Common Stock (the "Reporting Advisory Shares") beneficially owned by the Reporting Business Units of the Advisory Subsidiaries (the "Reporting Advisory Subsidiaries") as of January 28, 2025, which were acquired for an aggregate purchase price of approximately $3,266,234 and $42,202,032, respectively. Transactions made for investment purposes in the ordinary course of business of the Reporting Advisory Subsidiaries are undertaken solely for the benefit of the applicable client account and are independent from the strategic relationship with and investment in the Issuer made by the GIP Entities for their own accounts. Since the filing of Amendment No. 3 to the GIP Schedule 13D on June 28, 2024, Clearway Energy Group has acquired 98,375 shares of Class C Common Stock in connection with (i) the forfeiture of shares of restricted stock of the Issuer previously granted to certain Clearway Energy Group employees due to termination of service and (ii) the withholding of shares of restricted stock of the Issuer to satisfy tax obligations resulting from the vesting of such restricted stock previously granted by Clearway Energy Group under its Long Term Equity Incentive Program to certain of its employees. Additionally, Clearway Energy Group has disposed of 44,328 shares of Class C Common Stock in connection with a grant under its Long Term Equity Incentive Program to certain of its employees. The result of these transactions is a net acquisition of 54,047 shares of Class C common stock by Clearway Energy Group.

The purpose of the GIP Transaction was for BlackRock to acquire the business and assets of GIP Parent. GIP Parent acquired the GIP securities described in this Schedule 13D for investment purposes. Following the completion of the GIP Transaction, BlackRock formed BPM and established certain information and decision-making barriers between its business units, such that BPM will report the securities beneficially owned, or deemed to be beneficially owned, by the Reporting Business Units. With respect to the shares of Class A Common Stock and Class C Common Stock beneficially owned by the GIP Entities (the "GIP Shares"), the information in Item 4 of the GIP Schedule 13D is incorporated herein by reference. The securities reported herein include certain shares of Class A Common Stock beneficially owned by the Reporting Advisory Subsidiaries that were previously included in a statement on Schedule 13G/A filed with the SEC by BlackRock on July 8, 2024 and certain shares of Class C Common Stock beneficially owned by the Reporting Advisory Subsidiaries that were previously included in a statement on Schedule 13G/A filed with the SEC by BlackRock on January 19, 2024. The Reporting Advisory Subsidiaries did not acquire beneficial ownership of the Reporting Advisory Shares with the purpose or effect of changing or influencing the control of the Issuer or as a participant in any transaction having such purpose or effect, or in connection with any plan or proposal that would be subject to disclosure under Item 4 of Schedule 13D with respect to the Issuer. The Reporting Advisory Subsidiaries, as the investment advisers to certain client accounts, continue to hold the Reporting Advisory Shares in their ordinary course of business, not with the purpose or effect of changing or influencing the control of the Issuer or as a participant in any transaction having such purpose or effect, and not in connection with any plan or proposal that would be subject to disclosure under Item 4 of Schedule 13D with respect to the Issuer. However, BPM is filing this Schedule 13D because of the GIP Shares as described above in Item 3. With respect to the Reporting Advisory Shares, each of the Reporting Advisory Subsidiaries may evaluate on a continuing basis its client accounts' investment in the Issuer and BPM expects that such Reporting Advisory Subsidiaries may from time to time acquire or dispose of Class A Common Stock or Class C Common Stock on behalf of such client accounts. Any acquisitions or dispositions will depend upon (i) the price and availability of the Issuer's securities; (ii) subsequent developments concerning the Issuer's business and prospects and the industry in which the Issuer operates; (iii) the Reporting Advisory Subsidiaries' general investment policies with respect to the applicable accounts managed by the Reporting Advisory Subsidiaries; (iv) other investment and business opportunities available to the Reporting Advisory Subsidiaries on behalf of their clients; (v) general market and economic conditions; (vi) tax considerations; and (vii) such other factors as the Reporting Advisory Subsidiaries may consider relevant. Any such acquisitions or dispositions may be made, subject to applicable law, in open market transactions or privately negotiated transactions.

The responses of BPM to Rows (11) and (13) of the cover page of this Schedule 13D are incorporated herein by reference. None of the Covered Persons beneficially owns any shares of Class A Common Stock or Class C Common Stock. The aggregate percentages of shares of Class A Common Stock and Class C Common Stock reported as beneficially owned by the Reporting Business Units were calculated based on 34,613,853 and 82,831,652 shares of Class A Common Stock and Class C Common Stock, respectively, issued and outstanding as of October 28, 2024, as disclosed in the Issuer's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2024 filed with the SEC on October 30, 2024, plus 42,738,750 Class B units and 41,961,750 Class D units beneficially owned by the GIP Entities, as of January 28, 2025, and exchangeable at any time for shares of Class A Common Stock, and shares of Class C Common Stock, in each case, on a one-for-one basis, respectively.

Accounts managed by the Reporting Business Units have entered into short positions (the "Short Positions") with respect to 111,660 shares of Class C Common Stock (representing economic exposure to less than 0.1% of the total issued and outstanding shares of Class C Common Stock, as of January 28, 2025). The Short Positions provide the Reporting Business Units with economic results that are opposite to the economic results of ownership.

The Long Derivative Agreements provide such holder with economic results that are comparable to the economic results of ownership but do not provide it with the power to vote or direct the voting or dispose of or direct the disposition of the shares of Class A Common Stock and shares of Class C Common Stock that are the subject of the Long Derivative Agreements. BPM and the Reporting Business Units hereby expressly disclaim beneficial ownership of the shares of Class A Common Stock and shares of Class C Common Stock that are the subject of the Long Derivative Agreements.

In addition, accounts managed by the Reporting Business Units have entered into notional principal amount derivative agreements (the "Short Derivative Agreements") in the form of cash-settled swaps with respect to 6,847 shares of Class C Common Stock (representing economic exposure to less than 0.1% of the total issued and outstanding shares of Class C Common Stock as of January 28, 2025). The Short Derivative Agreements provide such holder with economic results that are opposite to the economic results of ownership but do not provide it with the power to vote or direct the voting or dispose of or direct the disposition of the shares of Class C Common Stock that are the subject of the Short Derivative Agreements. BPM and the Reporting Business Units hereby expressly disclaim beneficial ownership of the shares of Class C Common Stock that are the subject of the Short Derivative Agreements. The counterparties to the Short Derivative Agreements are unaffiliated third-party financial institutions. Except as set forth in this Schedule 13D, there are no contracts, arrangements, understandings or relationships between BPM and any other person with respect to any securities of the Issuer or among the Reporting Business Units, including but not limited to transfer or voting of any securities of the Issuer, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies (other than the transfer of voting rights with respect to the shares of Class A Common Stock and the shares of Class C Common Stock that are loaned out in the ordinary course of certain Reporting Business Units' securities lending programs).
