Item 3 of the Schedule 13D is hereby amended and supplemented as follows: The information set forth or incorporated by reference in Items 4, 5 and 6 of this Schedule 13D are incorporated by reference in its entirety into this Item 3. BPM has been delegated authority to file this Schedule 13D with respect to the 84,169,022 shares of Class C Common Stock beneficially owned by the GIP Entities. Certain of BlackRock's Advisory Subsidiaries in their capacity as investment advisers to certain client accounts, held beneficial ownership of 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. As of the date hereof, BPM has been delegated authority to file this Schedule 13D with respect to the 1,012,423 shares of Class C Common Stock (the "Reporting Advisory Shares") beneficially owned by the Reporting Advisory Subsidiaries as of April 29, 2026, which was acquired for an aggregate purchase price of approximately $26,837,528. 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.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows: Class A Conversion As previously disclosed in Amendment No. 2 to this Schedule 13D, On April 29, 2026, the Issuer filed the Charter Amendment, pursuant to which each share of Class A Common Stock issued and outstanding as of April 29, 2026 will be converted into one share of Class C Common Stock pursuant to the Charter Amendment. Pursuant to the Charter Amendment, an aggregate of 76,206 shares of Class A Common Stock beneficially owned by BPM are being converted into an equivalent number of shares of Class C Common Stock. The Class A Conversion automatically converted at 12:01 a.m., Eastern Time, on May 1, 2026 (the "Class A Conversion Time"). Voting Trust Agreement On April 29, 2026, Clearway Energy Group and the Voting Trustee entered into the Voting Trust Agreement. The final terms of the Voting Trust Agreement were modified since the filing of Amendment No. 2 to this Schedule 13D to contain certain clarifying revisions to further ensure that the provisions related to the exchange of Class B Units for shares of Class C Common Stock under the Third Amended Exchange Agreement and the pledging by Clearway Energy Group of Voting Trust Shares as collateral operate in a manner consistent with the general intent of the Voting Trust Agreement -- namely, to provide that the Class A Conversion, the Charter Amendment, the creation of the Voting Trust and certain other transactions do not result in any disproportionate change in Clearway Energy Group's total relative voting power compared to the total relative voting power that Clearway Energy Group would have held in the absence of such transactions. Pursuant to the terms of the Voting Trust Agreement, Clearway Energy Group, at the Class A Conversion Time, deposited into the Voting Trust a number of shares (the "Voting Trust Shares") of Class B Common Stock equal to the number of shares necessary to cause the total relative voting power that Clearway Energy Group holds in the Issuer as of immediately following the Class A Conversion to equal the total relative voting power that Clearway Energy Group holds in the Issuer as of immediately prior to the Class A Conversion. Based on the number of outstanding shares of each class of common stock on April 29, 2026, the number of Voting Trust Shares deposited into the Voting Trust at the Class A Conversion Time was 41,678,637 shares of Class B Common Stock. Under the Voting Trust Agreement, on any matter presented to the Company's stockholders for a vote, the Voting Trustee will be required to vote the Voting Trust Shares in the same proportion as the votes cast by all stockholders of the Company (including Clearway Energy Group with respect to any shares not held in the Voting Trust). Limited Liability Company Agreement In connection with the Class A Conversion, effective as of the Class A Conversion Time, the Issuer and Clearway Energy Group amended and restated the Fourth Amended and Restated Limited Liability Company Agreement of Clearway Energy LLC, a direct subsidiary of the Issuer, by entering into a Fifth Amended and Restated Limited Liability Company Agreement of Clearway Energy LLC (the "Amended Clearway LLC Agreement"). Under the Amended Clearway LLC Agreement, each outstanding Class A Unit of Clearway Energy LLC converts into one Class C Unit of Clearway Energy LLC, effective as of the Class A Conversion Time. The foregoing descriptions of the Voting Trust Agreement and form of Amended Clearway LLC Agreement do not purport to be complete and are subject to, and qualified in their entirety by, the full text of such agreements, which are attached as exhibits to this Schedule 13D and are incorporated herein by reference.
