Performance Measures In managing our business and assessing financial performance, we supplement the information provided by our condensed consolidated financial statements with other operating or statistical data and non-GAAP financial measures. These operating and financial measures are utilized by our management to evaluate our operating performance and, in certain cases, our ability to meet liquidity requirements. Although companies in the telecommunications industry may not define each of these measures in precisely the same way, we believe that these measures facilitate comparisons with other companies in the industry on key operating and financial measures. Beginning with the three months ended March 31, 2026, we shifted away from reporting customer performance measures to better align with the Company’s long-held priority on growing high-value accounts, which management believes is the best reflection of value creation versus customers. Postpaid Accounts A postpaid account is generally defined as a billing account that generates revenue. Postpaid accounts generally consist of customers that are qualified for postpaid service utilizing phones, 5G broadband gateways, fiber connections, mobile internet devices (including tablets and hotspots), wearables, DIGITS and other connected devices (including SyncUP and IoT), where they generally pay after receiving service. 44 Table of Contents The following table sets forth the number of ending postpaid accounts: As of June 30, | | | Change (in thousands) | | 2026 | | | 2025 | | | # | | | % Postpaid accounts (1) (2) (3) 34,700 | | | | 31,502 | | | | 3,198 | | | | 10 | | % (1) In the first quarter of 2026, we recognized a base adjustment to decrease postpaid accounts by 18,000, primarily due to combining certain business accounts that have multiple billing account numbers. (2) In the second quarter of 2026, Metronet agreed to repurchase certain customer accounts, resulting in a base adjustment to decrease postpaid accounts by 16,000. (3) In the second quarter of 2025, we acquired 85,000 postpaid accounts from Lumos. These base adjustments had no impact on postpaid net account additions. Postpaid Net Account Additions The following table sets forth the number of postpaid net account additions: Three Months Ended June 30, | | | Change | | | Six Months Ended June 30, | | | Change (in thousands) | | 2026 | | | 2025 | | | # | | | % | | | 2026 | | | 2025 | | | | | # | | | % Postpaid net account additions | | 277 | | | | 318 | | | | (41) | | | | (13) | | % | | | 494 | | | | 523 | | | | | | (29) | | | | (6) | | % Postpaid net account additions decreased 41,000, or 13%, for the three months ended June 30, 2026, primarily from: • Higher account deactivations driven by the impact of a growing account base, including following the UScellular Acquisition, and higher average broadband-only accounts; partially offset by • Higher gross account additions, including fiber account additions following the acquisition of Metronet. Postpaid net account additions decreased 29,000, or 6%, for the six months ended June 30, 2026, primarily from: • Higher account deactivations driven by the impact of a growing account base, including following the UScellular Acquisition, higher average broadband-only accounts and higher industry switching; partially offset by • Higher gross account additions, including fiber account additions following the acquisitions of Metronet and Lumos. Postpaid Account Churn Postpaid account churn represents the number of postpaid accounts whose service was deactivated as a percentage of the average number of postpaid accounts during the specified period further divided by the number of months in the period. The number of postpaid accounts whose service was deactivated is calculated net of accounts that subsequently had their service restored within a certain period of time and excludes accounts who received service for less than a certain minimum period of time, account mergers and account migrations. We believe that postpaid account churn provides management, investors and analysts with useful information to evaluate customer retention and loyalty. The following table sets forth the churn: Three Months Ended June 30, | | | Change | | | Six Months Ended June 30, | | | | | Change 2026 | | | 2025 | | 2026 | | | 2025 Postpaid account churn | | 0.99 | | % | | | 0.92 | | % | | | 7 bps | | | 1.02 | | % | | | 0.93 | | % | | | | | 9 bps Postpaid account churn increased 7 basis points for the three months ended June 30, 2026, primarily from higher average broadband-only accounts, including following the acquisition of Metronet. Postpaid account churn increased 9 basis points for the six months ended June 30, 2026, primarily from: • Higher average broadband-only accounts, including following the acquisitions of Metronet and Lumos; and • Higher industry switching. Postpaid Average Revenue Per Account Postpaid Average Revenue per Account (“ARPA”) represents the average monthly postpaid service revenue earned per account. Postpaid ARPA is calculated as Postpaid revenues for the specified period divided by the average number of postpaid 45 Table of Contents accounts during the period, further divided by the number of months in the period. We believe postpaid ARPA provides management, investors and analysts with useful information to assess and evaluate our postpaid service revenue realization and assists in forecasting our future postpaid service revenues on a per account basis. We consider postpaid ARPA to be indicative of our revenue growth potential, given management’s priority on growing high-value accounts through deepening customer relationships. The following table sets forth our operating measure ARPA: (in dollars) | | Three Months Ended June 30, | | | Change | | | Six Months Ended June 30, | | | | | Change 2026 | | | 2025 | | | $ | | | % | | | 2026 | | | 2025 | | | | $ | | | % Postpaid ARPA | | $ | | 152.91 | | | | $ | | 149.87 | | | | $ | | 3.04 | | | | 2 | | % | | | $ | | 152.42 | | | | $ | | 148.06 | | | | | | $ | | 4.36 | | | | 3 | | %
