Entry into a Material Definitive Agreement.

On May 20, 2026, Lumen Technologies, Inc. ("Lumen," "us," "we" or "our") issued a press release announcing that it, together with Qwest Corporation ("Qwest"), its wholly-owned subsidiary, has entered into a Support Agreement, dated May 18, 2026 (the "Support Agreement"), with certain holders (together, the "Supporting Noteholders") of Qwest's Existing Notes (as defined below) with respect to its previously announced exchange offers (as amended as set forth in this press release, the "Exchange Offers") to exchange Qwest's outstanding 6.5% Notes due 2056 (the "Existing 2056 Notes") and 6.75% Notes due 2057 (the "Existing 2057 Notes", and collectively with the Existing 2056 Notes, the "Existing Notes") for new notes to be issued by Qwest pursuant to the terms and conditions set forth in the Post-Effective Amendment (as defined below) to the Registration Statement on Form S-4, including a preliminary prospectus and consent solicitation statement forming a part thereof, dated May 20, 2026 (collectively, the "Prospectus").

Pursuant to the Support Agreement, the Supporting Noteholders have agreed to tender an aggregate principal amount of approximately $456 million of Old Qwest Notes in the Exchange Offers, consisting of approximately $296.5 million of the Existing 2056 Notes and $159.5 million of the Existing 2057 Notes in the Exchange Offers no later than 5:00 p.m., Eastern Time, on June 2, 2026, on the terms set forth in the Exchange Offers.

The obligations of each party under the Support Agreement will be subject to customary termination provisions, including automatic termination of the Exchange Offers are terminated or have not been consummated by 5:00 p.m., New York City time, on June 30, 2026.

The foregoing is a summary of the material terms of the Support Agreement and does not purport to be complete, and is subject to, and qualified by, the Support Agreement in its entirety, a copy of which is attached hereto as Exhibit 10.1 and incorporated by reference herein.

Item 8.01

Other Events.

On May 20, 2026, Lumen announced that it, together with Qwest, has amended the terms of its previously announced Exchange Offers. Pursuant to the amended terms of the Exchange Offers, Qwest is offering to exchange (i) any and all of the Existing 2056 Notes for newly issued 6.500% notes due 2051 (the "New 2051 Notes") and (ii) any and all of the Existing 2057 Notes for newly issued 6.750% notes due 2052 (the "New 2052 Notes," together with the New 2051 Notes, the "New Qwest Notes") or New 2051 Notes, in each case upon the terms and subject to the conditions set forth in the Prospectus. In connection with the Exchange Offers, Qwest and Lumen are also soliciting consents from holders of each series of the Existing Notes to certain proposed amendments to the indentures governing the Existing Notes (the "Consent Solicitations").

In connection with the amended terms, Qwest has eliminated the early tender participation date and extended the expiration date (as amended, the "Expiration Date") and the withdrawal deadline (as amended, the "Withdrawal Deadline") of each of the Exchange Offers to 5 p.m. ET on June 9, 2026.

Lumen has filed a post-effective amendment (the "Post-Effective Amendment") to the Registration Statement relating to the Exchange Offers with the Securities and Exchange Commission (the "SEC"). The Post-Effective Amendment to the registration statement has not yet become effective and the New Qwest Notes may not be issued, nor may the Exchange Offers be consummated, prior to the time that the Post-Effective Amendment becomes effective.

Holders of the Existing Notes are urged to carefully read the Post-Effective Amendment before making any decision with respect to the Exchange Offers and Consent Solicitations. Copies of the Post-Effective Amendment pursuant to which the Exchange Offers and Consent Solicitations are being made may be obtained free of charge at the SEC's website at www.sec.gov. or from D.F. King & Co., Inc., the information agent and exchange agent for the Exchange Offers and Consent Solicitations, at (800) 755-3105 (for information U.S. Toll-free) or (212) 257-2075 (information for banks and brokers).

This Current Report on Form 8-K is not an offer to buy or sell or the solicitation of an offer to sell with respect to any securities. The solicitation of offers to exchange the Existing Notes for New Qwest Notes is only being made pursuant to the terms of the Exchange Offers. Qwest is not making an offer of New Qwest Notes in any jurisdiction where the Exchange Offers are not permitted, and this Current Report on Form 8-K does not constitute an offer to participate in the Exchange Offers to any person in any jurisdiction where it is unlawful to make such an offer or solicitations.

The above-referenced press release is filed as Exhibit 99.1 to this Current Report and is incorporated herein by reference as if set forth in full.

Copies of the Preliminary Prospectus pursuant to which the Exchange Offers and Consent Solicitations are being made may be obtained from D.F. King & Co., Inc., the information agent and exchange agent for the Exchange Offers and Consent Solicitations. Requests for documentation and questions regarding procedures for tendering the Old Qwest Notes can be directed to D.F.

The consummation of each Exchange Offer and Consent Solicitation is subject to, and conditioned upon, the satisfaction or, where permitted, waiver of certain conditions, including, among other things, (i) the Registration Statement having been declared effective by the SEC and not being subject to a stop order by the SEC and (ii) the absence of any actual or threatened legal impediment to the acceptance for exchange of, or exchange of, the Old Qwest Notes.

A registration statement relating to these securities has been filed with the SEC but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This press release is for informational purposes only and is not an offer to buy or sell or the solicitation of an offer to sell with respect to any securities. The solicitation of offers to exchange the Old Qwest Notes for New Qwest Notes is only being made pursuant to the terms of the Exchange Offers. Qwest is not making an offer of New Qwest Notes in any jurisdiction where the Exchange Offers are not permitted, and this press release does not constitute an offer to participate in the Exchange Offers to any person in any jurisdiction where it is unlawful to make such an offer or solicitations.

Holders of the Old Qwest Notes are urged to carefully read the Preliminary Prospectus, the Registration Statement and the prospectus, when available, before making any decision with respect to the Exchange Offers and Consent Solicitations. None of Lumen, Qwest, the dealer managers, the trustee with respect to any series of Old Qwest Notes, the trustee with respect to any series of New Qwest Notes, the information agent and exchange agent for the Exchange Offers or any affiliate of any of them makes any recommendation as to whether holders of the Old Qwest Notes should exchange their Old Qwest Notes for New Qwest Notes in the Exchange Offers or deliver consents to the Proposed Amendments (as defined in the Preliminary Prospectus), and no one has been authorized by any of them to make such a recommendation.

Holders of the Old Qwest Notes must make their own decision as to whether to tender Old Qwest Notes and, if so, the principal amount of Old Qwest Notes to tender.
