F1 · kind: This Form 4 reports the withholding of shares to satisfy withholding tax obligations upon the vesting of restricted stock units which were previously granted and reported. The change in share ownership of the Reporting Person reported in this Form 4 results from the difference between (i) the number of restricted stock units subject to vesting that were previously granted and reported and (ii) the net number of shares actually received upon vesting of such restricted stock units after the withholding of shares to satisfy withholding tax obligations. This does not reflect an open market sale of securities.

F1 · price: On December 21, 2022, Core Scientific, Inc. (the "Issuer") and certain of its affiliates (collectively, the "Debtors") filed voluntary petitions (the "Chapter 11 Cases") in the United States Bankruptcy Court for the Southern District of Texas (the "Bankruptcy Court") seeking relief under Chapter 11 of Title 11 of the United States Code. On January 16, 2024, the Bankruptcy Court entered an order confirming the Debtors' Fourth Amended Joint Chapter 11 Plan of Reorganization of Core Scientific, Inc. and its Affiliated Debtors (with Technical Modifications) (the "Plan"), dated as of January 15, 2024. On January 23, 2024 (the "Effective Date"), the Plan became effective in accordance with its terms and the Debtors emerged from the Chapter 11 Cases.

F2 · price: On the Effective Date, pursuant to the terms of the Plan, the Issuer's common stock outstanding immediately before the Effective Date, par value $0.0001 per share (the "Old Common Stock"), was canceled and is of no further force or effect, and in exchange all holders of Old Common Stock received their pro rata share of new common stock, par value $0.00001 per share ("New Common Stock") representing, in the aggregate, approximately 21% of the shares of the reorganized Issuer (subject to dilution by awards issuable under a new management incentive plan and shares of New Common Stock issuable upon conversion or exercise of certain secured convertible notes, warrants, contingent value rights and settlement shares issued as part of the reorganization). The receipt of the New Common Stock in exchange for Old Common Stock was involuntary, without consideration and in accordance with the Plan approved by the Bankruptcy Court.

F3 · price: In accordance with the Plan, holders of the Issuer's Old Common Stock as of November 16, 2023 were granted the right to participate in a rights offering (the "Rights Offering") for the purchase, on a pro rata basis, of up to $55 million of New Common Stock to be issued pursuant to the Plan. The Reporting Person did not purchase any New Common Stock under the Rights Offering. In addition, certain members of the Issuer's board of directors and management, including the Reporting Person, committed to purchase a portion of any New Common Stock not otherwise subscribed for in the Rights Offering pursuant to a backstop commitment letter (the "Backstop Commitment Letter"). The Reporting Person did not purchase any New Common Stock under the Backstop Commitment Letter, but received a commitment premium of shares of New Common Stock as consideration for entering into the Backstop Commitment Letter.
