The Board of Directors

Frontier Communications Parent, Inc.:

We consent to the incorporation by reference in the registration statement on Form S-8 of Frontier Communications Parent, Inc. (the Company) of our reports dated March 3, 2021, with respect to the consolidated balance sheets of Frontier Communications Corporation and subsidiaries (Debtor-In-Possession) (Old Frontier) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive loss, equity (deficit), and cash flows for each of the years in the three-year period ended December 31, 2020, and the related notes (collectively, the consolidated financial statements), and the effectiveness of internal control over financial reporting as of December 31, 2020, which reports appear in the December 31, 2020 annual report on Form 10-K of Old Frontier. The Company is the successor issuer to Old Frontier under Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended.

Our report on the consolidated financial statements dated March 3, 2021 contains an explanatory paragraph that states that Old Frontier has filed petitions for relief under Chapter 11 of the U.S. Bankruptcy Code, which raises substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty.
