ALTICE USA REPORTS THIRD QUARTER 2025 RESULTS
NEW YORK (November 6, 2025) -- Altice USA (NYSE: ATUS) today reports results for the third quarter ended September 30, 2025.
Dennis Mathew, Altice USA Chairman and Chief Executive Officer, said: "In the third quarter, we delivered record gross margin performance and improved operational efficiencies, reaffirmed our full-year Adjusted EBITDA outlook, continued to elevate our customer and network experience, and achieved a milestone of over 700 thousand fiber customers. At the same time, we faced intense competition and a sustained low-growth environment, which resulted in softer broadband subscriber trends. Looking ahead, we are sharpening our go-to-market and base management strategies to strengthen our broadband performance and improve our revenue trajectory in this highly competitive landscape. We remain unwavering in our discipline and focus as we continue to build a more resilient business, positioned for sustainable, long-term growth and enhanced value for our shareholders."

Reconciliation of Non-GAAP Financial Measures
We define Adjusted EBITDA, which is a non-GAAP financial measure, as net income (loss) excluding income taxes, non-operating income or expenses, gain (loss) on extinguishment of debt and write-off of deferred financing costs, gain (loss) on interest rate swap contracts, gain (loss) on derivative contracts, gain (loss) on investments and sale of affiliate interests, interest expense, net, depreciation and amortization, share-based compensation, restructuring, impairments and other operating items (such as significant legal settlements and contractual payments for terminated employees). We define Adjusted EBITDA margin as Adjusted EBITDA divided by total revenue.
Adjusted EBITDA eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of our business and from intangible assets recognized from acquisitions, as well as certain non-cash and other operating items that affect the period-to-period comparability of our operating performance. In addition, Adjusted EBITDA is unaffected by our capital and tax structures and by our investment activities.
We believe Adjusted EBITDA is an appropriate measure for evaluating our operating performance. Adjusted EBITDA and similar measures with similar titles are common performance measures used by investors, analysts and peers to compare performance in our industry. Internally, we use revenue and Adjusted EBITDA measures as important indicators of our business performance and evaluate management’s effectiveness with specific reference to these indicators. We believe Adjusted EBITDA provides management and investors a useful measure for period-to-period comparisons of our core business and operating results by excluding items that are not comparable across reporting periods or that do not otherwise relate to our ongoing operating results. Adjusted EBITDA should be viewed as a supplement to and not a substitute for operating income (loss), net income (loss), and other measures of performance presented in accordance with U.S. generally accepted accounting principles (“GAAP”). Since Adjusted EBITDA is not a measure of performance calculated in accordance with GAAP, this measure may not be comparable to similar measures with similar titles used by other companies.
We also use Free Cash Flow (defined as net cash flows from operating activities less cash capital expenditures) as a liquidity measure. We believe this measure is useful to investors in evaluating our ability to service our debt and make continuing investments with internally generated funds, although it may not be directly comparable to similar measures reported by other companies.

(7)Relationship Net Promoter Score (rNPS) measures a customer's overall loyalty and satisfaction with a company and gauges how likely a customer is to recommend the company.
(8)Adjusted EBITDA is provided on a forward-looking basis. The Company has not included a reconciliation of projected Adjusted EBITDA to net income, which is the most directly comparable GAAP measure, in reliance on the unreasonable efforts exception provided under Item 10(e)(1)(i)(B) of Regulation S-K. The Company’s projected Adjusted EBITDA excludes certain items that are inherently uncertain and difficult to predict and may significantly impact the projection of net income.
(9)Mobile penetration of broadband base is expressed as the percentage of customers subscribing to both broadband and mobile services divided by the total broadband customer base. Excludes mobile only customers.
(10)Net debt, defined as the principal amount of debt less cash, and excluding finance leases and other notes.

(12)The weighted average cost of debt includes floating to fixed interest rate swaps at Cablevision Lightpath LLC and Altice USA Consolidated.
(13)Customer metrics as of September 30, 2024 reflect adjustments to align to the Company’s bulk residential subscriber count policy, resulting in an increase of 4.7 thousand residential customer relationships, 3.8 thousand broadband customers and 5.2 thousand video customers. The impact of these adjustments to customer relationships, broadband and video customer net additions was not material for any period presented and as such prior period metrics were not restated.
(14)Subscriber net additions (losses) and passings additions exclude 8.3 thousand passings, 2.1 thousand customer relationships, 1.9 thousand broadband subscribers and 0.5 thousand video subscribers that were transferred in connection with a small system sale in Q4-24.
(15)Total passings represents the estimated number of single residence homes, apartments and condominium units passed by the HFC and FTTH network in areas serviceable without further extending the transmission lines. In addition, it includes commercial establishments that have connected to our hybrid-fiber-coaxial (HFC) and fiber-to-the-home (FTTH) network. Broadband services were not available to approximately 26 thousand total passings and telephony services were not available to approximately 460 thousand total passings as of September 30, 2025.
(16)Total Unique Customer Relationships represent the number of households/businesses that receive at least one of our fixed-line services. Customers represent each customer account (set up and segregated by customer name and address), weighted equally and counted as one customer, regardless of size, revenue generated, or number of boxes, units, or outlets on our HFC and FTTH network. Free accounts are included in the customer counts along with all active accounts, but they are limited to a prescribed group. Most of these accounts are also not entirely free, as they typically generate revenue through pay-per-view or other pay services and certain equipment fees. Free status is not granted to regular customers as a promotion. In counting bulk residential customers, such as an apartment building, we count each subscribing unit within the building as one customer, but do not count the master account for the entire building as a customer. We count a bulk commercial customer, such as a hotel, as one customer, and do not count individual room units at that hotel.
(17)Total Customer Relationship metrics do not include mobile-only customers.
(18)Residential ARPU is calculated by dividing the average monthly revenue for the respective period derived from the sale of broadband, video, telephony and mobile services to residential customers by the average number of total residential customers for the same period and excludes mobile-only customer relationships.
(19)Broadband ARPU is calculated by dividing the average monthly residential broadband revenue for the respective period by the average number of total residential broadband customers for the same period.
(20)Mobile lines represent the number of residential and business customers’ wireless connections, which include mobile phone handsets and other mobile wireless connected devices. An individual customer relationship may have multiple mobile lines. The FY 2024, Q1 2025, Q2 2025, and Q3 2025 ending lines include approximately 4.4 thousand, 7.5 thousand, 10.8 thousand, and 14.2 thousand lines related to business customers, respectively. The service revenue related to these business customers is reflected in "Business services and wholesale" in the table above.
(21)Represents the estimated number of single residence homes, apartments and condominium units passed by the FTTH network in areas serviceable without further extending the transmission lines. In addition, it includes commercial establishments that have connected to our FTTH network.
(22)Represents number of households/businesses that receive at least one of our fixed-line services on our FTTH network. FTTH customers represent each customer account (set up and segregated by customer name and address), weighted equally and counted as one customer, regardless of size, revenue generated, or number of boxes, units, or outlets on our FTTH network. Free accounts are included in the customer counts along with all active accounts, but they are limited to a prescribed group. Most of these accounts are also not entirely free, as they typically generate revenue through pay-per view or other pay services and certain equipment fees. Free status is not granted to regular customers as a promotion. In counting bulk residential customers, such as an apartment building, we count each subscribing unit within the building as one customer, but do not count the master account for the entire building as a customer. We count a bulk commercial customer, such as a hotel, as one customer, and do not count individual room units at that hotel.
(23)Beginning on March 31, 2025, we are required to pay interest on the Incremental Term Loan B-5 at a rate equal to the alternate base rate (“ABR”), plus the applicable margin, where the ABR is the greater of (x) prime rate or (y) the federal funds effective rate plus 50 basis points, and the applicable margin for any ABR loan is 1.50% per annum. Prior to March 31, 2025, we paid interest at a rate equal to Synthetic USD London Interbank Offered Rate plus 2.50% per annum.

(24)The Incremental Term Loan B-6 is due on the earlier of (i) January 15, 2028 and (ii) April 15, 2027 if, as of such date, any Incremental Term Loan B-5 borrowings are still outstanding, unless the Incremental Term Loan B-5 maturity date has been extended to a date falling after January 15, 2028.
(25)Under the extension amendment to the Lightpath credit agreement entered into in February 2024, the aggregate principal amount of revolving loan commitments available under the credit agreement increased to $115 million, of which $95 million of revolving credit commitments, if drawn, would be due on the earlier of (i) June 15, 2027 and (ii) the date that is five business days after any Extension Breach Date (as defined in Lightpath's amended credit agreement); and $20 million of revolving credit commitments, if drawn, would be due on November 30, 2025.
(26)In January 2025, Lightpath entered into a refinancing amendment to its credit agreement which reduced the applicable margins on its Term SOFR loans (as defined in Lightpath's amended credit agreement) from 3.25% per annum to 3.00%. Additionally, after giving effect to the refinancing amendment, interest on borrowings made under the Term SOFR loans are calculated without giving effect to the spread adjustments (0.11448%, 0.26161% and 0.42826% for interest periods of one, three and six months, respectively) initially provided for under Lightpath's amended credit agreement.
