Exhibit 99.3

Explanation of Non-GAAP Financial Measures

The Company reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). In the Company’s quarterly results releases, trend schedules, conference calls, slide presentations, and webcasts, it may use or discuss Non-GAAP financial measures, as defined by Regulation G of the Securities and Exchange Commission. The Company believes that the presentation of certain Non-GAAP financial measures in these materials provides information that is useful to investors because it allows for a more direct comparison of the Company’s performance for the period reported with the Company’s performance in prior periods. The Company cautions that Non-GAAP financial measures should be considered in addition to, but not as a substitute for, the Company’s reported GAAP results. Management defines the Non-GAAP financial measures used as follows:

•Non-GAAP Organic Contract Revenues - contract revenues from businesses that are included for the entire period in both the current and prior year periods, excluding contract revenues from storm restoration services, adjusted for the additional week in the fourth quarter of fiscal 2021, as a result of the Company’s 52/53 week fiscal year. Non-GAAP Organic Contract Revenue change percentage is calculated as the change in Non-GAAP Organic Contract Revenues from the comparable prior year period divided by the comparable prior year period Non-GAAP Organic Contract Revenues. Management believes Non-GAAP Organic Contract Revenues is a helpful measure for comparing the Company’s revenue performance with prior periods. For comparison purposes, Lumen’s Non-GAAP Organic Contract Revenue and Non-GAAP Organic Contract Revenue Growth percentage excludes the estimated contract revenues for the quarter ended April 30, 2022 related to the ILEC (incumbent local exchange carrier) business in 20 states it sold to Brightspeed on October 3, 2022.

•Non-GAAP Adjusted EBITDA - net income before interest, taxes, depreciation and amortization, gain on sale of fixed assets, stock-based compensation expense, and certain non-recurring items. Management believes Non-GAAP Adjusted EBITDA is a helpful measure for comparing the Company’s operating performance with prior periods as well as with the performance of other companies with different capital structures or tax rates.

•Notional Net Debt - Notional net debt is a Non-GAAP financial measure that is calculated by subtracting cash and equivalents from the aggregate face amount of outstanding debt. Management believes notional net debt is a helpful measure to assess the Company’s liquidity.

1 The Company has a 52/53 week fiscal year. All quarter periods presented contain 13 weeks except for the quarter ended January 30, 2021, which contained an additional week of operations.

The Non-GAAP adjustment for the additional week of operations for the quarter ended January 30, 2021 is calculated as (i) contract revenues less (ii) contract revenues from storm restoration services (iii) divided by 14 weeks.
