Constellation Energy Corp 8-K Report, Corporate Update (Dec 23, 2025)

Filed December 23, 2025For Securities:CEG

Summary

Constellation Energy Generation, LLC has announced an extension of its private exchange offers and related consent solicitations concerning Calpine Corporation's outstanding notes. The primary purpose of these actions is to facilitate the elimination of restrictive covenants and certain events of default in the governing indentures for Calpine's existing senior unsecured and senior secured notes. This strategic move is directly tied to the previously announced merger between Constellation Energy Corporation and Calpine. The extension pushes the expiration date for tendering notes and delivering consents from January 8, 2026, to January 12, 2026. Importantly, Constellation has already received the requisite consents to amend the Calpine indentures, indicating strong support from noteholders for removing these restrictive provisions. The elimination of these covenants is expected to simplify Calpine's debt structure and is a condition for the proposed merger's completion.
