Item 1.01. Entry into a Material Definitive Agreement
Exchange Offers and Consent Solicitation
As previously announced, on January 7, 2026, Constellation Energy Corporation (Nasdaq: CEG), a Pennsylvania corporation (“CEG Parent”) and Constellation Energy Generation, LLC, a Pennsylvania limited liability company (“Constellation”), completed the previously announced transactions contemplated by the Agreement and Plan of Merger, dated January 10, 2025 (the “Merger Agreement”), by and among CEG Parent, Calpine Corporation, a Delaware corporation (“Calpine”), CPN CS Holdco Corp., a Delaware corporation and wholly owned subsidiary of Calpine (“New Company”), CPN CKS Corp., a Delaware corporation and wholly owned subsidiary of New Company (“Company Merger Sub”), Cascade Transco Inc., a Delaware corporation and an indirect, wholly owned subsidiary of CEG Parent (“First Merger Sub”), Cascade Transco – 1, LLC, a Delaware limited liability company and an indirect, wholly owned subsidiary of CEG Parent (“Second Merger Sub”), and Volt Energy Holdings GP, LLC, a Delaware limited liability company, solely in its capacity as the representative of the stockholders of Calpine. Capitalized terms used but not defined herein have the meanings ascribed to them in the Merger Agreement. As a result of the transactions contemplated by the Merger Agreement, Calpine became a wholly owned subsidiary of Constellation.
Upon closing, Calpine (as a wholly owned subsidiary of Constellation) remained the issuer of (i) $650 million in aggregate principal amount of 4.625% Senior Notes due 2029 (the “2029 Senior Notes”); (ii) $850 million in aggregate principal amount of 5.000% Senior Notes due 2031 (the “2031 Senior Notes”) and (iii) $900 million in aggregate principal amount of 3.750% Senior Secured Notes due 2031 (the “2031 Senior Secured Notes” and, together with the 2029 Senior Notes and the 2031 Senior Notes, the “Calpine Notes”). On January 15, 2026 (the “Settlement Date”), Constellation completed its previously announced private offers to exchange any and all of the outstanding Calpine Notes for, to the extent held by eligible holders, newly issued (i) 4.625% Senior Notes due 2029 (“New 2029 Senior Notes”), (ii) 5.000% Senior Notes due 2031 (“New February 2031 Senior Notes”) and (iii) 3.750% Senior Notes due 2031 (“New March 2031 Senior Notes,” and, together with the New 2029 Senior Notes and the New February 2031 Senior Notes, the “Constellation Notes”) by Constellation having the same interest payment dates, maturity dates and interest rates as the Calpine Notes (each, an “Exchange Offer”, and collectively, the “Exchange Offers”). In connection with the Exchange Offers, Constellation also solicited consents (the “Consent Solicitations”) on behalf of Calpine from eligible holders to amend the Calpine Notes and the related indentures under which they were issued (the “Calpine Indentures”) to eliminate substantially all of the restrictive covenants, restrictive provisions and events of default, other than payment-related and bankruptcy-related events of default (the “Proposed Amendments”).
Pursuant to the Exchange Offers and Consent Solicitations, $2,289,722,000 aggregate principal amount of Calpine Notes were validly tendered and subsequently accepted. Such accepted Calpine Notes have been retired and canceled and will not be reissued.
The Exchange Offers have expired, and are no longer open to participation by any eligible holders of the Calpine Notes.
Following receipt of the requisite number of consents to adopt the Proposed Amendments with respect to the Calpine Notes and the Calpine Indentures, on the Settlement Date, Calpine entered into supplemental indentures with the trustee for the Calpine Notes to effect the Proposed Amendments. Reference is made to the supplemental indentures attached to this report as Exhibit 4.1, Exhibit 4.2 and Exhibit 4.3.
Constellation Notes
The Constellation Notes were issued under an indenture, dated as of September 28, 2007, between Constellation and U.S. Bank Trust Company, National Association, as trustee.
The New 2029 Senior Notes will bear interest at the rate of 4.625% per year. The New February 2031 Senior Notes will bear interest at the rate of 5.000% per year. The New March 2031 Senior Notes will bear interest at the rate of 3.750% per year.
Interest on the New 2029 Senior Notes and New February 2031 Senior Notes is payable on February 1 and August 1 of each year, beginning on February 1, 2026. Interest on the New March 31 Senior Notes is payable on March 1 and September 1 of each year, beginning on March 1, 2026.
The New 2029 Senior Notes will mature on February 1, 2029. The New February 2031 Senior Notes will mature on February 1, 2031. The New March 2031 Senior Notes will mature on March 1, 2031.
The Constellation Notes are subject to optional redemption as provided in the New 2029 Senior Notes, the New February 2031 Senior Notes and the New March 2031 Senior Notes.
Reference is made to the Form of New 2029 Senior Note attached as Exhibit 4.4, the Form of New February 2031 Senior Note attached as Exhibit 4.5 and the Form of New March 2031 Senior Note attached as Exhibit 4.6 for additional covenants, events of default and other terms and conditions of the Senior Notes.

This combined Current Report on Form 8-K is being furnished separately by Constellation Energy Corporation and Constellation Energy Generation, LLC, (collectively, the “Registrants”). 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. These forward-looking statements include, but are not limited to, statements regarding the exchange offers, the consent solicitations, the expected timing and likelihood of completion of the exchange offers and consent solicitations, the pro forma combined company and its operations, strategies, plans, synergies, opportunities and anticipated future performance and capital structure. Information adjusted for the acquisition of Calpine Corporation should not be considered a forecast of future results. Although the Registrants believe these forward-looking statements are reasonable, statements made regarding future results are not guarantees of future performance and are subject to numerous assumptions, uncertainties and risks that are difficult to predict. Forward-looking statements are based on current expectations, estimates and assumptions that involve a number of risks and uncertainties that could cause actual results to differ materially from those projected.
Actual outcomes and results may differ materially from the results stated or implied in the forward-looking statements included in this Current Report on Form 8-K due to a number of factors, including, but not limited to the risk that problems may arise in successfully integrating the businesses of the companies, which may result in the combined company not operating as effectively and efficiently as expected, and the risk that the combined company may be unable to achieve synergies or other anticipated benefits of the acquisition of Calpine Corporation or it may take longer than expected to achieve those synergies or benefits. 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. Risk Factors, (b) Part II, ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and (c) Part II, ITEM 8. Financial Statements and Supplementary Data: Note 18, Commitments and Contingencies; (2) the Registrants’ Third Quarter 2025 Quarterly Report on Form 10-Q in (a) Part II, ITEM 1A. Risk Factors, (b) Part I, ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and (c) Part I, ITEM 1. Financial Statements: Note 14, Commitments and Contingencies; and (3) other factors discussed in filings with the Securities and Exchange Commission by the Registrants.
Investors are cautioned not to place undue reliance on these forward-looking statements, whether written or oral, which apply only as of the date of this Current Report on Form 8-K. Neither Registrant undertakes any obligation to publicly release any revision to its forward-looking statements to reflect events or circumstances after the date of this Current Report on Form 8-K.
