(HOUSTON, Texas) – December 2, 2020 – Calpine Corporation announced today that it has commenced a cash tender offer to purchase up to $335,000,000 in aggregate principal amount (the “Tender Cap Amount”) of its outstanding 5.250% Senior Secured Notes due 2026 (CUSIP Nos.: 131347 CK0 / U13055 AR6 / U13055 AS4) (the “Notes”) (the “Offer”). The terms and conditions of the Offer are described in an Offer to Purchase, dated December 2, 2020 (the “Offer to Purchase”).

The following table summarizes the terms of the Offer:

(1)     Per $1,000 principal amount of Notes tendered and accepted for purchase.

(2)     The Early Tender Payment is included in the Total Consideration for Notes tendered at or prior to the Early Tender Date.

(3)     Excludes accrued and unpaid interest from the last interest payment date up to, but not including, the applicable settlement date, which will be paid in addition to the Tender Offer Consideration or the Total Consideration, as applicable.

The Offer expires at 11:59 p.m., New York City Time, on December 30, 2020, unless extended or earlier terminated (the “Expiration Date”). The consideration for each $1,000 principal amount of Notes validly tendered and not validly withdrawn at or prior to 5:00 p.m. New York City Time on December 15, 2020, unless extended (the “Early Tender Date”), and accepted for purchase pursuant to the Offer will be the Total Consideration set forth in the table above. The consideration for each $1,000 principal amount of Notes validly tendered after the Early Tender Date and at or prior to the Expiration Date and accepted for purchase pursuant to the Offer will be the Tender Offer Consideration set forth in the table above, which consists of the Total Consideration less the Early Tender Payment set forth in the table above. Holders of Notes tendered after the Early Tender Date will not be eligible to receive the Early Tender Payment.

Holders of Notes validly tendered and accepted for purchase pursuant to the Offer will receive the applicable consideration described above, plus accrued and unpaid interest from the last interest payment date applicable to the Notes to, but not including, the applicable settlement date.

If the aggregate principal amount of Notes validly tendered exceeds the Tender Cap Amount, Calpine Corporation, if it accepts for purchase any Notes under such circumstances, will accept for purchase only an aggregate principal amount of Notes up to the Tender Cap Amount. In such circumstance, the amount of Notes purchased will be prorated, with the aggregate principal amount of each Holder’s validly tendered Notes accepted for purchase determined by multiplying each holder’s tender by a proration factor, and rounding the product down to the nearest $1,000. Furthermore, if the Offer is fully subscribed as of the Early Tender Date, holders who validly tender Notes following the Early Tender Date will not have any of their Notes accepted for purchase.

Tendered Notes may be withdrawn prior to 5:00 p.m., New York City time, on December 15, 2020 (the “Withdrawal Date”). Holders of Notes who tender their Notes after the Withdrawal Date, but at or prior to the Expiration Date, may not withdraw their tendered Notes. The consummation of the Offer is not conditioned upon any minimum amount of Notes being tendered, but is subject to, and conditioned upon, the satisfaction or waiver of certain conditions described in the Offer to Purchase, including, among others, Calpine Corporation consummating one or more financing transactions. Calpine intends to use a portion of the net proceeds from such financing transactions, together with cash on hand (if necessary), to fund the aggregate consideration and accrued interest for all Notes validly tendered (and not withdrawn) pursuant to the Offer and accepted for purchase by us, and to pay all fees and expenses incurred in connection with the Offer. Calpine Corporation intends to issue a conditional notice of partial redemption for the Notes to redeem $335 million in aggregate principal amount of the Notes less the aggregate principal amount of Notes purchased in the Offer. This announcement does not constitute a notice of redemption of the Notes.
