All Rights Reserved. 2 Non-GAAP Measures This presentation includes certain historical and forward-looking non-GAAP financial measures, including but not limited to adjusted EBITDA, adjusted EBITDA margin, and free cash flow, each excluding the effects of special items, and adjustments to GAAP and other non-GAAP measures to exclude the effect of special items. In addition to providing key metrics for management to evaluate the company’s performance, we believe these measurements assist investors in their understanding of period-to-period operating performance and in identifying historical and prospective trends. Reconciliations of non-GAAP financial measures to the most comparable GAAP measures are included in the financial schedules to the Company’s accompanying earnings release. Reconciliation of information and additional non-GAAP historical financial measures that may be discussed during the call, along with further descriptions of non-GAAP financial measures, will be available in the Investor Relations portion of the company’s website at http://ir.lumen.com. Non-GAAP measures are not presented to be replacements or alternatives to the GAAP measures, and investors are urged to consider these non-GAAP measures in addition to, and not in substitution for, measures prepared in accordance with GAAP. Lumen may present or calculate its non-GAAP measures differently from other companies.
