Business Segment

Year ended December 31, 2024 compared to the year ended December 31, 2023 and the year ended December 31, 2023 compared to the year ended December 31, 2022.

Business segment revenue decreased $1.2 billion for the year ended December 31, 2024 compared to December 31, 2023 and decreased $1.5 billion for the year ended December 31, 2023 compared to December 31, 2022. Approximately $547 million of the decrease for the year ended December 31, 2024 compared to December 31, 2023 was due to the sale of the EMEA business and select CDN contracts in the fourth quarter of 2023. Approximately $1.0 billion of the decrease for the year ended December 31, 2023 compared to December 31, 2022, was due to the sale of the Latin American, ILEC and EMEA businesses in late 2022 and 2023. More specifically, within each product category for the year ended December 31, 2024 compared to December 31, 2023 and for the year ended December 31, 2023 compared to December 31, 2022:

•Grow decreased $121 million and $124 million, respectively, reflecting decreases of approximately $272 million and $370 million associated with the sale of the divested businesses. For the year ended December 31, 2024 compared to December 31, 2023, we saw growth in IP services of $107 million and an increase in revenue from dark fiber and conduit of $112 million, partially offset by declines in other products, including declines in wavelength services by $42 million. For the year ended December 31, 2023 compared to December 31, 2022, we saw an increase of $244 million primarily in our IP, wavelengths, dark fiber, enterprise broadband and colocation products and services.

•Nurture decreased $532 million and $635 million, respectively, approximately $88 million and $262 million of which was associated with the sale of the divested businesses. The remainder of the declines were principally attributable to declines in traditional VPN services of $314 million and $261 million, respectively, and declines in Ethernet services of $117 million and $112 million, respectively.

•Harvest decreased by $408 million and $732 million, respectively, approximately $70 million and $370 million of which was associated with the sale of the divested businesses. The remainder of the decline was principally attributable to a $252 million and $265 million decline, respectively, in legacy voice and private line services.

•Other decreased by $159 million and $25 million, respectively. For the year ended December 31, 2024 as compared to December 31, 2023, approximately $93 million of this decline was attributable to the above-mentioned sale of select CDN contracts in late 2023 and decreases in equipment sales revenue of approximately $29 million. For the year ended December 31, 2023 as compared to December 31, 2022, approximately $48 million of the decline was attributable to decreased CDN revenue leading up to the above-mentioned sale, partially offset by an increase in equipment sales revenue of $35 million.

Business segment expense decreased by $576 million for the year ended December 31, 2024 compared to December 31, 2023 and decreased $371 million for the year ended December 31, 2023 compared to December 31, 2022. For the year ended December 31, 2024 compared to December 31, 2023 this decrease was primarily driven by (i) a decrease of $209 million due to the above-mentioned sale of the EMEA business and select CDN contracts in 2023, (ii) a $166 million reduction in overall network expense and (iii) a decrease of $138 million in employee-related costs. For the year ended December 31, 2023 compared to December 31, 2022, the decrease was primarily due to (i) the sale of the divested businesses of $230 million, (ii) an $81 million decrease in employee-related costs, and (iii) a $68 million decrease in other network related costs.

Business segment adjusted EBITDA as a percentage of revenue was 52%, 52% and 55% for the years ended December 31, 2024, 2023 and 2022.

Mass Markets Segment

Year ended December 31, 2024 compared to the year ended December 31, 2023 and the year ended December 31, 2023 compared to the year ended December 31, 2022.

Mass Markets segment revenue decreased by $229 million for the year ended December 31, 2024 compared to December 31, 2023 and decreased $1.4 billion for the year ended December 31, 2023 compared to December 31, 2022. Approximately $1.1 billion of the decreases for the year ended December 31, 2023 compared to December 31, 2022 was due to the sale of our ILEC business in the fourth quarter of 2022. More specifically, within each product category for the year ended December 31, 2024 compared to December 31, 2023 and for the year ended December 31, 2023 compared to December 31, 2022:

•Fiber Broadband revenue increased $99 million and $33 million, respectively, primarily driven by growth in the number of fiber customers associated with our continued increase in enabled locations from our Quantum Fiber buildout. For the year ended December 31, 2023 compared to December 31, 2022, the increase was partially offset by a decrease of $41 million due to the sale of the ILEC business.

•Other Broadband revenue decreased $228 million and $768 million, respectively, primarily due to fewer customers for our lower speed copper-based broadband services. For the year ended December 31, 2023 compared to December 31, 2022, there was an additional decrease of $563 million due to the sale of the ILEC business.

•Voice and Other decreased $100 million and $670 million, respectively. For the year ended December 31, 2024 compared to December 31, 2023, the decrease was principally due to the continued loss of copper-based voice customers. For the year ended December 31, 2023 compared to December 31, 2022, the decrease was due to (i) a $472 million decrease due to the sale of the ILEC business, (ii) continued loss of copper-based voice customers, and (iii) the recognition in the first quarter of 2022 of $59 million of previously deferred revenue related to the CAF II program, which lapsed on December 31, 2021.

Mass Markets segment expense decreased by $165 million for the year ended December 31, 2024 compared to December 31, 2023 primarily due to (i) a decrease of $60 million in employee-related costs, (ii) a decrease of $36 million in other network related costs, (iii) a decrease of $33 million in professional fees, and (iv) a decrease of $10 million in network expenses. Mass Markets segment expense decreased $312 million for the year ended December 31, 2023 compared to December 31, 2022 primarily due to a $295 million decrease due to the ILEC divestiture and a $37 million decrease in professional fees, partially offset by an increase of $42 million in employee-related costs and $27 million in marketing and advertising costs.

Mass Markets segment adjusted EBITDA as a percentage of revenue was 53%, 51% and 60% for the years ended December 31, 2024, 2023 and 2022, respectively.
