**OPTIMUM REPORTS FIRST QUARTER 2026 RESULTS** 

NEW YORK (May 7, 2026) -- Optimum Communications, Inc. (NYSE: OPTU) today reports results for the first quarter ended March 31, 2026.

**Dennis Mathew, Optimum Chairman and Chief Executive Officer**, said: *"The first quarter reflects the deliberate choices we are making to build a more resilient business over time. We continued to navigate an intense competitive environment with strategic focus, executing against our core priorities of strengthening broadband trends, maintaining financial discipline, and investing for long-term value creation. These efforts contributed to year-over-year margin expansion, underscoring our focus on operating efficiency and disciplined execution. In doing so, we took meaningful steps toward simplifying how we go to market, improving the quality of our subscriber base and advancing our convergence strategy to drive more consistent returns. We were encouraged by strong momentum in mobile, which delivered its strongest quarter in six years with 52k net additions, reinforcing our conviction in multi-product relationships, with growth increasingly driven by customers with stronger engagement, supporting lower churn and improved lifetime value. We believe these actions, alongside our ongoing work to evolve our capital structure, are the right foundation for creating durable long-term value for our customers, our employees, and 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.

(1)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.

(2)Convergence ARPU is calculated by dividing the average monthly revenue for the respective period derived from the sale of broadband and mobile services to residential customers by the average number of total residential broadband customers for the same period and excludes mobile-only customer relationships.

(3)See "Reconciliation of Non-GAAP Financial Measures" beginning on page 7 of this earnings release.

(4)Capital intensity refers to total cash capital expenditures as a percentage of total revenue.

(5)Broadband subscriber net adds video subscriber net adds in Q1-26 include subscriber adjustments taken in the quarter related to prior periods. Excluding these adjustments broadband subscriber net losses would have been 56k and video subscriber net losses would have been 50k.

(6)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.

(7)Video ARPU is calculated by dividing the average monthly residential video revenue for the respective period by the average number of total residential video customers for the same period.

(8)Net debt, defined as the principal amount of debt less cash, and excluding finance leases and other notes.

(9)L2QA leverage is calculated as quarter end net debt consolidated divided by the last two quarters of Adjusted EBITDA annualized.

(10)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.

(11)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.

(12)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 March 31, 2026.

(13)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.

(14)Total Customer Relationship metrics do not include mobile-only customers.

(15)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 2025 and Q1 2026 ending lines include approximately 17.6 thousand and 20.9 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.

(16)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.

(17)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.
