Lumen Technologies, Inc. and its wholly-owned subsidiary Qwest Corporation entered into a Support Agreement, dated May 18, 2026, with certain holders (Supporting Noteholders) of Qwest's Existing Notes. The agreement pertains to previously announced exchange offers for Qwest's 6.5% Notes due 2056 (Existing 2056 Notes) and 6.75% Notes due 2057 (Existing 2057 Notes). Supporting Noteholders have committed to tender an aggregate principal amount of approximately $456 million of Old Qwest Notes, consisting of $296.5 million of Existing 2056 Notes and $159.5 million of Existing 2057 Notes, by June 2, 2026. In exchange, noteholders will receive newly issued 6.500% Notes due 2051 or 6.750% Notes due 2052, on a par-for-par basis, fully and unconditionally guaranteed by Lumen. The terms of the Exchange Offers have been amended, eliminating the early tender participation date and extending the expiration date and withdrawal deadline to June 9, 2026, at 5 p.m. ET. Qwest and Lumen are also soliciting consents from holders of each series of Existing Notes for proposed amendments to their indentures. A post-effective amendment to the Registration Statement on Form S-4 has been filed with the SEC but is not yet effective; new notes cannot be issued, nor can the offers be consummated, until it becomes effective.
