Core Adjusted EBITDA, Adjusted Free Cash Flow and Adjusted Free Cash Flow margin are non-GAAP financial measures. These non-GAAP financial measures should be considered in addition to, but not as a substitute for, the information provided in accordance with GAAP. Reconciliations for these non-GAAP financial measures to the most directly comparable GAAP financial measures are provided in the Reconciliation of Non-GAAP Financial Measures to GAAP Financial Measures tables. We are not able to forecast Net income on a forward-looking basis without unreasonable efforts due to the high variability and difficulty in predicting certain items that affect Net income, including, but not limited to, Special Items, Income tax expense and Interest expense. Core Adjusted EBITDA should not be used to predict Net income as the difference between this measure and Net income is variable.

Higher gross account additions, including fiber account additions following the acquisitions of Metronet and Lumos

Partially offset by higher account deactivations driven by higher industry switching and the impact of a growing account base, including following the acquisition of UScellular

During Q2 2025, we acquired 85,000 postpaid accounts from Lumos.

During Q3 2025, we acquired 1,448,000 postpaid accounts, net of certain base adjustments, through the UScellular acquisition.

During Q3 2025, we acquired 633,000 postpaid accounts from Metronet and other acquisitions.

During Q1 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.

These base adjustments had no impact on postpaid net account additions.
