In the second quarter we achieved sustainable operational and financial improvements across the business, with significant achievements in our customer experience and field operations translating into higher customer satisfaction metrics and reduced call volume and service visits.

•Total Fiber Broadband PSUs: Quarterly Fiber (FTTH) broadband net additions were +40k in Q2 2023, our best quarter for fiber net adds. Fiber broadband net adds were driven by both higher fiber gross additions and increased migrations of existing customers. Total fiber broadband customers reached 250k as of the end of Q2 2023.

•Optimum Mobile has approximately 264k mobile lines as of the end of Q2 2023, adding +16k mobile net additions in Q2 2023 (+35k net additions excluding customers receiving free service(4)), reaching 5.8% penetration of the Company's total broadband customer base.

Lightpath revenue decline is driven by Sprint early termination revenue(2) in the prior period of approximately $2.3 million; excluding this early termination revenue, Lightpath revenue would have grown +1.1% in Q2 2023.

•News and Advertising revenue was down -14.8% YoY to $113.5 million in Q2 2023, or down -8.4% excluding political revenue.

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 expense and other operating items (such as significant legal settlements, contractual payments for terminated employees, and impairments).

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 the operating performance of the Company. 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 the Company’s 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 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 Operating Free Cash Flow (defined as Adjusted EBITDA less cash capital expenditures), and Free Cash Flow (defined as net cash flows from operating activities less cash capital expenditures) as indicators of the Company’s financial performance. We believe these measures are two of several benchmarks used by investors, analysts and peers for comparison of performance in the Company’s industry, although they may not be directly comparable to similar measures reported by other companies.

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 family unit within the building as one customer, but do not count the master account for the entire building as a customer.
