Lumen Announces Early Tender Results of Exchange Offers for

Unsecured Notes of Lumen and Level 3

DENVER, Sept. 17, 2024 /PRNewswire/ — Lumen Technologies, Inc. (NYSE: LUMN) (“Lumen”) announced the early results of its offers to exchange newly-issued secured notes for certain of its outstanding unsecured senior notes. In addition, Lumen also announced the early results of the offers by Level 3 Financing, Inc., its indirect, wholly-owned subsidiary (“Level 3” and, together with Lumen, the “Issuers”), to exchange newly-issued second lien notes for certain of its outstanding unsecured senior notes.

Lumen Exchange Offers

As previously announced, Lumen has offered to exchange (collectively, the “Lumen Exchange Offers”) up to $500,000,000 (the “Lumen Notes Cap”) maximum aggregate principal amount of its newly-issued 10.000% Secured Notes due 2032 (the “New Lumen Notes”) and certain cash consideration, as applicable, for its outstanding:

subject to the terms and conditions set forth in Lumen’s private offering memorandum, dated September 3, 2024 (the “Lumen Offering Memorandum”), including the $100,000,000 limit (the “New Notes Series Cap”) on the maximum aggregate principal amount of New Lumen Notes that Lumen may issue in exchange for the 2029 Lumen Notes.

Based on data provided by Global Bondholder Services Corporation, the following table sets forth the approximate aggregate principal amount of each series of Subject Lumen Notes that (i) were validly tendered and not validly withdrawn on or prior to 5:00 p.m., New York City time, on September 16, 2024 (the “Early Tender Time”), and (ii) Lumen expects to accept for purchase, subject to all conditions to the Exchange Offers having been satisfied or waived by Lumen.

Because the aggregate principal amount of Subject Lumen Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time did not reach the Lumen Notes Cap or the New Notes Series Cap, Lumen expects to accept for purchase all of the Subject Lumen Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time on the terms and subject to the conditions described below.

On or about September 24, 2024 (such date, subject to change or cancellation without notice, the “Early Settlement Date”), Lumen currently expects to accept for purchase Subject Lumen Notes validly tendered and not validly withdrawn prior to the Early Tender Time in exchange for issuing $438,305,345 aggregate principal amount of New Lumen Notes and paying $13,694,400 cash (excluding accrued but unpaid interest further discussed below), subject to all conditions to the Exchange Offers having been satisfied or waived by Lumen.

Subject Lumen Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time will be accepted for purchase in accordance with the terms and subject to the conditions of the Lumen Offering Memorandum, including those governing the authorized minimum denominations of each series of Subject Lumen Notes that will be accepted in the Exchange Offers and the minimum denominations of New Lumen Notes that will be issued in exchange for such Subject Lumen Notes.

All Subject Lumen Notes that were validly tendered in a Lumen Exchange Offer at or prior to the Early Tender Time will have priority over Subject Lumen Notes that are validly tendered after the Early Tender Time, even if such Subject Lumen Notes tendered after the Early Tender Time have a higher Acceptance Priority Level than the Subject Lumen Notes tendered at or prior to the Early Tender Time and even if Lumen elects to forego an Early Settlement Date.

Level 3 Exchange Offers

As previously announced, Level 3 has offered to exchange (collectively, the “Level 3 Exchange Offers” and, together with the Lumen Exchange Offers, the “Exchange Offers”) up to $350,000,000 (the “Level 3 Notes Cap”) maximum aggregate principal amount of its newly-issued 10.000% Second Lien Notes due 2032 (the “New Level 3 Notes” and, together with the New Lumen Notes, the “New Notes”) for its outstanding:

subject to the terms and conditions set forth in Level 3’s private offering memorandum, dated September 3, 2024 (the “Level 3 Offering Memorandum”).

Based on data provided by Global Bondholder Services Corporation, the following table sets forth the approximate aggregate principal amount of each series of Subject Level 3 Notes that (i) were validly tendered and not validly withdrawn on or prior to the Early Tender Time, and (ii) Level 3 expects to accept for purchase, subject to all conditions to the Exchange Offers having been satisfied or waived by Level 3.

Because the aggregate principal amount of Subject Level 3 Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time reached the Level 3 Notes Cap, no Subject Level 3 Notes tendered for exchange after the Early Tender Time will be accepted for exchange, regardless of the Acceptance Priority Level thereof.

On or about the Early Settlement Date, Level 3 currently expects to accept for purchase Subject Level 3 Notes validly tendered and not validly withdrawn prior to the Early Tender Time in exchange for issuing $349,999,160 aggregate principal amount of New Level 3 Notes, subject to all conditions to the Exchange Offers having been satisfied or waived by Level 3.

3

Subject Level 3 Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time will be accepted for purchase in accordance with the terms and subject to the conditions of the Level 3 Offering Memorandum, including those governing the authorized minimum denominations of each series of Subject Level 3 Notes that will be accepted in the Exchange Offers and the minimum denominations of New Level 3 Notes that will be issued in exchange for such Subject Level 3 Notes.

Because the aggregate amount of New Level 3 Notes expected to be issued in exchange for Subject Level 3 Notes validly tendered (and not validly withdrawn) at or prior to the Early Tender Time would otherwise exceed the Level 3 Notes Cap, the 4.625% Level 3 Notes accepted for purchase will be pro rated on the terms described in the Level 3 Offering Memorandum and illustrated in the table above.

Additional Information about the Exchange Offers

The Exchange Offers will expire at 5:00 p.m., New York City time, on October 1, 2024, unless extended by the applicable Issuer (such time and date with respect to an Exchange Offer, as it may be extended for such Exchange Offer, the “Expiration Time”). The Early Tender Time was the deadline for holders to validly withdraw tenders of Subject Notes. Accordingly, Subject Notes tendered prior to or after the Early Tender Time may no longer be withdrawn or revoked, subject to applicable law.

In addition to the Early Exchange Consideration described in the tables above, holders of Subject Notes will be entitled to accrued but unpaid interest with respect to the Subject Notes tendered and not withdrawn prior to the Early Tender Time from the latest applicable interest payment date to, but excluding, the date on which such Subject Notes are exchanged for New Notes (such date, the “Settlement Date”), subject to adjustments in certain limited circumstances described in the applicable Offering Memorandum.

The final Settlement Date, if applicable, for each Exchange Offer is expected to be on or about the third business day following the Expiration Time, subject to all conditions to such Exchange Offer having been satisfied or waived by the applicable Issuer.

Lumen may amend, extend, terminate or withdraw any or all of the Lumen Exchange Offers (including by modifying the amount of the Lumen Notes Cap or New Notes Series Cap), and Level 3 may amend, extend, terminate or withdraw any or all of the Level 3 Exchange Offers (including by modifying the amount of the Level 3 Notes Cap), in each case, (i) in their sole discretion without extending the applicable Withdrawal Deadline or amending the withdrawal rights of any applicable Eligible Holder (as described below), and (ii) regardless of whether any other Exchange Offer is amended, extended, terminated or withdrawn.

Eligible Holders must make their own independent evaluation of the financial merits of the applicable Exchange Offer and the information included in the applicable Offering Memorandum. In making an investment decision, Eligible Holders must rely on their own independent examination of the value of the applicable Subject Notes and the applicable New Notes, the issuer of such New Notes, and the terms of the applicable Exchange Offer and New Notes, including the merits and risks involved with exchanging Subject Notes for New Notes and cash consideration (as applicable).

This press release does not constitute (i) an offer to sell, or a solicitation of an offer to buy, the New Notes, (ii) an offer to buy, or a solicitation of an offer to sell, the Subject Notes, or (iii) a solicitation to participate in the Exchange Offers, which are being made solely in accordance with the Offering Memoranda.
