BALTIMORE--(BUSINESS WIRE)--Dec. 9, 2025-- Constellation Energy Generation, LLC (“Constellation”), a Pennsylvania limited liability company, announced today that it has commenced private offers to exchange any and all of the outstanding (i) 4.625% Senior Unsecured Notes due 2029 (“Existing Unsecured 2029 Notes”), (ii) 5.000% Senior Unsecured Notes due 2031 (“Existing Unsecured 2031 Notes”) and (iii) 3.750% Senior Secured Notes (“Existing Secured 2031 Notes” and, together with the Existing Unsecured 2029 Notes and the Existing Unsecured 2031 Notes, the “Calpine Notes”) of Calpine Corporation (“Calpine”), a Delaware corporation, for, to the extent held by eligible noteholders, newly issued (i) 4.625% Senior Unsecured Notes due 2029 (“New Unsecured 2029 Notes”), (ii) 5.000% Senior Unsecured Notes due 2031 (“New Unsecured February 2031 Notes”) and (iii) 3.750% Senior Unsecured Notes due 2031 (“New Unsecured March 2031 Notes,” and, together with the New Unsecured 2029 Notes and New Unsecured February 2031 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”). The New February 2031 Unsecured Notes and New March 2031 Unsecured Notes will no longer have certain redemption features associated with their respective Calpine Notes and will contain superior call protection to the Calpine Notes. Eligible holders of Calpine Notes tendered by the Early Tender Deadline (as defined below) and not validly withdrawn before the Withdrawal Deadline (as defined below), will also receive the Cash Consideration (as defined below).

Concurrently with the Exchange Offers, Constellation is soliciting consents (collectively, the “Consent Solicitations”) from eligible holders of Calpine Notes, on behalf of Calpine, to amend the Calpine Notes and the indentures governing the Calpine Notes (collectively, the “Calpine Indentures”) to eliminate substantially all of the restrictive covenants, restrictive provisions and events of default from the Calpine Indentures and the Calpine Notes, other than payment-related and bankruptcy-related events of default. Consents of the holders of not less than a majority in aggregate principal amount of the Calpine Notes must be obtained for the amendments to the Calpine Notes and the Calpine Indentures to be effective. Holders validly tendering their Calpine Notes will be deemed to have delivered consents to the proposed amendments with respect to such tendered Calpine Notes. Holders will not be permitted to tender their Calpine Notes without delivering consents or to deliver consents without tendering their Calpine Notes.

The Exchange Offers and Consent Solicitations are being made upon the terms and conditions set forth in an exchange offers memorandum and consent solicitations statement, dated December 9, 2025 (the “Offering Memorandum”), copies of which will be made available to holders of the Calpine Notes eligible to participate in the Exchange Offers. The following table sets forth the Total Exchange Consideration (as defined below) and the Exchange Consideration (as defined below) being offered for the Calpine Notes:

The Exchange Offers and Consent Solicitations will expire at 5:00 p.m., New York City time, on January 8, 2026, unless such date is extended or earlier terminated (such date and time, as they may be extended, the “Expiration Date”). Tenders of Calpine Notes may be validly withdrawn and consents revoked at any time prior to 5:00 p.m., New York City time, on December 22, 2025 (such date and time, as they may be extended, the “Withdrawal Deadline”), but tenders and consents not so validly withdrawn will be irrevocable after the Withdrawal Deadline, except in certain limited circumstances where additional withdrawal rights are required by law. Constellation reserves the right to terminate, withdraw, amend or extend the Exchange Offers and Consent Solicitations in its sole discretion, subject to the terms and conditions set forth in the Offering Memorandum.

Subject to the terms and conditions set forth in the Offering Memorandum, for each $1,000 principal amount of Calpine Notes validly tendered in the Exchange Offer by 5:00 p.m., New York City time, on December 22, 2025 (such date and time, as they may be extended, the “Early Tender Deadline”), and not validly withdrawn by the Withdrawal Deadline, each eligible holder of Calpine Notes will be eligible to receive Constellation Notes in an equal principal amount as the tendered Calpine Notes accepted for exchange and a cash payment of an amount equal to the product of $1.00 (with respect to the Existing Unsecured 2029 Notes), $1.00 (with respect to the Existing Unsecured 2031 Notes) and $2.50 (with respect to the Existing Secured 2031 Notes), in each case multiplied by a fraction, the numerator of which is the aggregate principal amount of the applicable series of Calpine Notes outstanding as of the Early Tender Deadline and the denominator of which is the aggregate principal amount of the applicable series of Calpine Notes validly tendered by the Early Tender Deadline and not validly withdrawn by the Withdrawal Deadline (the “Cash Consideration” and, together with such amount of Constellation Notes, the “Total Exchange Consideration”). As a result, the Cash Consideration for each series of Calpine Notes will range from $1.00 per $1,000 principal amount with respect to the Existing Unsecured 2029 Notes, $1.00 per $1,000 principal amount with respect to the Existing Unsecured 2031 Notes or $2.50 per $1,000 principal amount with respect to the Existing Secured 2031 Notes (in each case, if all eligible noteholders of each such series of the Calpine Notes tender), respectively, to approximately $2.00 per $1,000 principal amount with respect to the Existing Unsecured 2029 Notes, $2.00 per $1,000 principal amount with respect to the Existing Unsecured 2031 Notes or $2.50 per $1,000 principal amount with respect to the Existing Secured 2031 Notes, respectively (in each case, if eligible noteholders of a simple majority of the aggregate principal amount of such series of the Calpine Notes tender).

Eligible holders who validly tender their Calpine Notes after the Early Tender Deadline but on or prior to the Expiration Date will be eligible to receive $970 principal amount of the Calpine Notes per $1,000 principal amount of Calpine Notes validly tendered but no Cash Consideration (the “Exchange Consideration”).

The Constellation Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. No tender of Calpine Notes will be accepted if it would result in the issuance of less than $2,000 principal amount of the Calpine Notes. If the principal amount of Constellation Notes validly tendered after the Early Tender Deadline that would otherwise be required to be delivered in exchange for a tender of Calpine Notes would not equal $2,000 or an integral multiple of $1,000 in excess thereof, then the principal amount of such Constellation Notes will be rounded down to $2,000 or the nearest integral multiple of $1,000 in excess thereof, and Constellation will pay cash (in lieu of such Constellation Notes not delivered) equal to the remaining portion of the Exchange Consideration for such Calpine Notes plus accrued and unpaid interest with respect to that portion to, but not including, the Settlement Date.

Constellation’s obligation to accept and exchange the Calpine Notes validly tendered pursuant to the Exchange Offers is subject to certain conditions as set forth in the Offering Memorandum. The Exchange Offers and Consent Solicitations are not conditioned upon any minimum aggregate principal amount of Calpine Notes being validly tendered for exchange, but are conditioned upon, among others, the receipt of the requisite consents to adopt the proposed amendments to the Calpine Indentures and the consummation of the previously announced merger transaction contemplated by that certain Agreement and Plan of Merger, dated as of January 10, 2025, by and among Constellation Energy Corporation and Calpine (the “Merger Agreement”). Other than the consummation of the merger transaction contemplated by the Merger Agreement (without which the Exchange Offers will not be consummated, neither the Exchange Consideration nor the Total Exchange Consideration will be paid, nor will the amendments contemplated by the Consent Solicitations become effective), Constellation may generally waive any condition with respect to the Exchange Offers and Consent Solicitations, in its sole discretion, at any time.

The Exchange Offers are being made only to holders of Calpine Notes who satisfy the eligibility conditions described under “Disclaimer” below. Holders of Calpine Notes who desire a copy of the eligibility letter should contact D.F. King & Co., Inc., the information agent and exchange agent for the Exchange Offers and Consent Solicitations, at (866) 796-3441 or via e-mail at CEG@dfking.com. Banks and brokers should call (212) 448-4476. Eligible holders may go to www.dfking.com/CEG to confirm their eligibility. D.F. King & Co., Inc. will also provide copies of the Offering Memorandum to eligible holders of Calpine Notes.

Holders of Calpine Notes are advised to check with any bank, securities broker or other intermediary through which they hold Calpine Notes as to when such intermediary needs to receive instructions from a holder in order for that holder to be able to participate in, or (in the circumstances in which revocation is permitted) revoke their instruction to participate in, the Exchange Offers and Consent Solicitations before the deadlines specified herein and in the Offering Memorandum. The deadlines set by each clearing system for the submission and withdrawal of exchange instructions will also be earlier than the relevant deadlines specified herein and in the Offering Memorandum.
