    Upon the closing of the Mergers on January 7, 2026, Calpine Construction Finance Company, L.P., an indirect, wholly owned subsidiary of Calpine (“CCFC”), remains party to a Credit Agreement with Citibank, N.A.

The CCFC Term Loan Agreement consists of a first lien senior secured term loan (the “CCFC Term Loan”). On August 2, 2023, CCFC and the other parties thereto amended and restated the original CCFC Term Loan Agreement.

Subsequently, on November 18, 2025, CCFC incurred a replacement tranche of first lien senior secured term loans, which increased its existing CCFC Term Loan by $225 million and repriced such existing CCFC Term Loan to reduce the applicable spread over the SOFR rate from 2.00% to 1.75% under the CCFC Term Loan Agreement.

The GPC Term Loan Agreement consists of a $1,771 million senior secured term loan facility (of which $1,415 million term loans are currently outstanding (the “GPC Term Loans”)) and a $250 million letter of credit facility. The GPC Term Loans bear interest at Term SOFR plus a percentage equal to (a) until May 31, 2025, 1.5%, (b) from such date until May 31, 2028, 1.625%, and (c) from such date until the maturity of the GPC Term Loans, 1.75% (plus, in each case, applicable Term SOFR adjustment).

    Section 2 – Financial Information

    Item 2.01. Completion of Acquisition or Disposition of Assets

     

    As discussed in the Introductory Note above, on January 7, 2026, CEG Parent and Constellation completed the previously announced transactions contemplated by the Merger Agreement.

     

    Pursuant to the Merger Agreement, (i) on January 2, 2026, Calpine, New Company and Company Merger Sub completed an internal reorganization pursuant to which Company Merger Sub merged with and into Calpine, with Calpine surviving the merger as a wholly owned subsidiary of New Company and the holders of Company Common Shares and Company Restricted Stock Units becoming holders of Common Shares and Restricted Stock Units of New Company (“RSUs”), and on January 5, 2026, Calpine converted into a Delaware limited liability company (the “Reorganization”), (ii) on January 7, 2026, at the First Effective Time, First Merger Sub merged with and into New Company, with New Company surviving the merger as a wholly owned subsidiary of Constellation and (iii) on January 7, 2026, at the Second Effective Time, New Company merged with and into Second Merger Sub, with Second Merger Sub surviving the merger as a wholly owned subsidiary of Constellation (clauses (ii) and (iii), collectively, the “Mergers”). As a result of the Reorganization and the Mergers, Calpine became a wholly owned subsidiary of Constellation.

     

     

     

    The merger consideration consisted of (i) an aggregate of 50,000,000 newly issued shares of common stock, no par value, of CEG Parent (the “Stock Consideration”) and (ii) $4.50 billion in cash minus the amount of Company Expenses. As a result of the Mergers, the former stockholders of Calpine received approximately 13.8% of the outstanding CEG Parent common stock in the aggregate based upon the outstanding shares of CEG Parent common stock as of January 6, 2026.

     

    In connection with closing of the Mergers, outstanding Calpine equity-based awards were treated as follows:

     

    At the First Effective Time, each outstanding RSU issued by New Company in respect of Company Restricted Stock Units issued by Calpine pursuant to the Calpine Corporation 2024 Equity Incentive Plan (whether vested or unvested) was fully vested, canceled and converted into the right to receive, in respect of each such RSU: (i) the Per Share Cash Consideration, without interest, (ii) the Per Share Stock Consideration, (iii) any cash in lieu of fractional shares of CEG Parent common stock was paid in accordance with the Merger Agreement and (iv) an amount in cash (without interest and less any applicable taxes required to be withheld) equal to any dividend equivalents with respect to such RSU that were unpaid as of the First Effective Time (which amounts in respect of such dividend equivalents were first satisfied from any escrow account related thereto).

     

    The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which was attached as Exhibit 2.1 to the Current Report on Form 8-K dated January 13, 2025 (File No. 001-41137) and is incorporated herein by reference. The Merger Agreement has been incorporated by reference into this Current Report on Form 8-K to provide information regarding its terms. It is not intended to provide any other factual information about CEG Parent, Constellation, Calpine or any other party. The Merger Agreement contains representations and warranties that the parties thereto made to each other as of a specific date. The assertions embodied in the representations and warranties in the Merger Agreement were made solely for purposes of the Merger Agreement and the transactions and agreements contemplated thereby among the respective parties thereto and may be subject to important qualifications and limitations agreed to by the parties thereto in connection with negotiating the terms thereof and are not intended to, and do not, confer upon any person other than the parties thereto any rights or remedies thereunder, including the right to rely upon the representations and warranties set forth therein. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to stockholders or may have been used for the purpose of allocating risk among the parties to the Merger Agreement rather than establishing matters as facts.

     

    Section 2 – Financial Information

    Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant

The issuance of the Stock Consideration to the former stockholders of Calpine was made in reliance upon the exemption from the registration requirements of the Securities Act of 1933, as amended, provided by Section 4(a)(2) thereof as a transaction by an issuer not involving any public offering.

     

    Section 5 - Corporate Governance and Management

    Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

     

    Effective upon the closing of the Mergers on January 7, 2026, Daniel Eggers, CEG Parent’s Executive Vice President and Chief Financial Officer, was promoted to Senior Executive Vice President, Finance and Data Economy, and no longer serves as Chief Financial Officer, and Shane Smith, CEG Parent’s Senior Vice President, Treasury and Credit, was promoted to Executive Vice President and Chief Financial Officer. Concurrently with the effectiveness of Mr. Smith’s promotion, Mr. Smith also assumed the additional role of principal financial officer of CEG Parent, replacing Mr. Eggers. As previously reported, Mr. Smith’s compensation includes an annual base salary of $725,000, an annual incentive program target opportunity of 85% of his base salary, and a long-term incentive target valued at $2,500,000, consistent with the terms of the Constellation Energy Corporation 2022 Long-Term Incentive Plan.

     

     

     

    Mr. Smith, age 46, had served as CEG Parent’s Senior Vice President, Treasury and Credit since CEG Parent’s separation from Exelon in February 2022, prior to which Mr. Smith served as Vice President, Finance, Constellation for Exelon beginning in April 2020. Mr. Smith received his bachelor’s degree with a dual concentration in Finance and Marketing from Boston College and his MBA from the University of Maryland.

Information contained herein relating to one of the Registrants has been furnished by such Registrant on its own behalf. Neither Registrant makes any representation as to information relating to the other Registrant.

     

    This Current Report on Form 8-K contains certain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks and uncertainties. Words such as “could,” “may,” “expects,” “anticipates,” “will,” “targets,” “goals,” “projects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “predicts,” and variations on such words, and similar expressions that reflect the Registrants’ current views with respect to future events and operational, economic, and financial performance, are intended to identify such forward-looking statements.

Other unpredictable or unknown factors not discussed in this Current Report on Form 8-K could also have material adverse effects on forward-looking statements.

     

    The factors that could cause actual results to differ materially from the forward-looking statements made by the Registrants include those factors discussed herein, as well as the items discussed in (1) the Registrants’ 2024 Annual Report on Form 10-K in (a) Part I, ITEM 1A.
