We use Adjusted EBITDA, Adjusted EBITDAR, Adjusted Free Cash Flow and Adjusted Capital Expenditures as key measures of the operational performance of our business. Our management, including the chief operating decision-maker, consistently uses these measures for internal reporting and the evaluation of business objectives, opportunities and performance, and the determination of management compensation. Management believes that Adjusted Free Cash Flow provides investors with useful information about the ability of our core operations to generate cash flow. Because capital spending is necessary to maintain our operational capabilities, we believe that capital expenditures represents a recurring and necessary use of cash. As such, we believe investors should consider our capital spending and payments due under our master leases with Uniti when evaluating the amount of cash provided by our operating activities. Windstream Holdings II, LLC ("Windstream", "we", "us", "our", or "the Company") has presented in this Investor Supplement unaudited adjusted results, which excludes depreciation and amortization, straight-line expense under the master leases with Uniti Group, Inc. ("Uniti"), equity-based compensation expense, restructuring charges, and certain other costs. We have also presented certain measures of our operating performance, on an adjusted basis, that reflects the impact of the cash payment due under the master leases with Uniti. In addition, we have presented on a pro forma adjusted basis Adjusted EBITDAR, Kinetic revenues and Kinetic contribution margin as if the transition from Connect America Fund (“CAF”) - Phase II to Rural Digital Opportunity Fund (“RDOF”) funding occurred beginning in the first quarter of 2021 as further discussed below. Our business operations are organized into three segments: Kinetic, Enterprise and Wholesale. The Kinetic business unit primarily serves customers in markets in which we are the incumbent local exchange carrier (“ILEC”) and provides services over network facilities operated by us. Kinetic service revenues include state Universal Service Fund (“USF”) revenues and, beginning in 2022, also include amounts received from the RDOF. Kinetic service revenues in 2021 included amounts received from the CAF - Phase II, which funding ended as of December 31, 2021. The Enterprise and Wholesale business units primarily serve customers in markets in which we are a competitive local exchange carrier (“CLEC”) and provide services over network facilities primarily leased from other carriers. During the first quarter of 2022, we made changes to further align our customer base and service offerings within our ILEC and CLEC markets. The significant changes to our previous segment structure included: (1) shifting additional business customers with the majority of their service locations residing in ILEC markets from the Enterprise segment to the Kinetic segment and (2) shifting additional governmental customers from Kinetic and Enterprise to Wholesale. Additionally, we have shifted certain fiber leasing costs from Enterprise to Kinetic and Wholesale and updated the assignment of certain corporate and support costs including insurance and engineering to the three business segments. Prior period segment information has been revised to reflect these customer alignment changes. A reconciliation of previously reported to revised segment and consolidated information is included within this Investor Supplement. During the second quarter of 2021, the Company created a new engineering and fiber construction organization to manage its broadband network expansion. The Company will add nearly 1,000 employees and acquire construction equipment in supporting this new organization. As a result, the Company has incurred incremental start-up costs and capital expenditures associated with this initiative. 1

Available capacity under credit facility excludes outstanding letters of credit of $79.5 million of which $52.5 million was issued to Universal Service Administrative Company as a condition for Windstream receiving RDOF funding. Adjusted Free Cash Flow is Adjusted EBITDA less adjusted capital expenditures, additional rent paid for growth capital expenditures funded by Uniti and cash paid for interest on long-term debt obligations plus funding received from Uniti for growth capital expenditures and adjusted for cash refunded (paid) for income taxes, net. Margins are calculated by dividing the respective profitability measures by total revenues and sales. 2021 Adjusted EBITDA is Adjusted EBITDAR after the cash payment due under the master leases with Uniti excluding additional rent paid for growth capital expenditures funded by Uniti and increased for cash received from Uniti per the settlement agreement. 2022 Adjusted EBITDAR is earnings before interest expense, income taxes and depreciation and amortization and is calculated as operating income (loss) excluding depreciation and amortization, straight-line expense under the master leases with Uniti, equity-based compensation expense, restructuring charges, and certain other costs. Pro forma Adjusted EBITDAR is Adjusted EBITDAR as if the transition from CAF Phase II to RDOF funding occurred beginning in the first quarter of 2021. 2
