Quarterly Investor Update September 3rd, 2020

Safe Harbor StatementForward-looking Language This presentation contains "forward-looking statements," related to future events. Forward-looking statements address Frontier’s expected future business, financial performance, and financial condition, and contain words such as "expect," "anticipate," "intend," "plan," "believe," "seek," "see," "may," "will," "would," or "target." Forward-looking statements by their nature address matters that are, to different degrees, uncertain. For Frontier, particular uncertainties that could cause actual results to be materially different than those expressed in such forward-looking statements include: our ability to continue as a going concern; our ability to successfully consummate a financial restructuring of our existing debt, existing equity interests, and certain other obligations (the Restructuring), and emerge from cases commenced under chapter 11 (the Chapter 11 Cases) of the United States Bankruptcy Code, including by satisfying the conditions and milestones in the restructuring support agreement; our ability to improve our liquidity and long-term capital structure and to address our debt service obligations through the Restructuring and the potential adverse effects of the Chapter 11 Cases on our liquidity and results of operations; our ability to maintain relationships with suppliers, customers, employees and other third parties as a result of the Restructuring and the Chapter 11 Cases; the effects of the Restructuring and the Chapter 11 Cases on the Company and the interests of various constituents; risks and uncertainties associated with the Restructuring, including our ability to receive approvals for debtor-in-possession financing and successfully consummate the Restructuring; our ability to comply with the restrictions expected to be imposed by covenants in debtor-in-possession and exit financing; the length of time that the Company will operate under Chapter 11 protection and the continued availability of operating capital during the pendency of the Chapter 11 Cases; risks associated with third party motions in the Chapter 11 Cases, which may interfere with the Company’s ability to consummate the Restructuring; increased administrative and legal costs related to the Chapter 11 process; declines in revenue from our voice services, switched and nonswitched access and video and data services that we cannot stabilize or offset with increases in revenue from other products and services; our ability to successfully implement strategic initiatives, including opportunities to enhance revenue and realize productivity improvements; our ability to effectively manage our operations, operating expenses, capital expenditures, debt service requirement and cash paid for income taxes and liquidity; competition from cable, wireless and wireline carriers, satellite, and OTT companies, and the risk that we will not respond on a timely or profitable basis; our ability to successfully adjust to changes in the communications industry, including the effects of technological changes and competition on our capital expenditures, products and service offerings; risks related to disruption in our networks, infrastructure and information technology that result in customer loss and/or incurrence of additional expenses; the impact of potential information technology or data security breaches or other cyber-attacks or other disruptions; our ability to retain or attract new customers and to maintain relationships with customers, employees or suppliers; our ability to secure, continue to use or renew intellectual property and other licenses used in our business; our ability to hire or retain key personnel; our ability to dispose of certain assets or asset groups on terms that are attractive to us, or at all; the effects of changes in the availability of federal and state universal service funding or other subsidies to us and our competitors and our ability to obtain future subsidies, including participation in the proposed RDOF program; our ability to meet our CAF II obligations and the risk of penalties or obligations to return certain CAF II funds; our ability to defend against litigation and potentially unfavorable results from current pending and future litigation; our ability to comply with applicable federal and state consumer protection requirements; the effects of state regulatory requirements that could limit our ability to transfer cash among our subsidiaries or dividend funds up to the parent company; the effects of governmental legislation and regulation on our business, including costs, disruptions, possible limitations on operating flexibility and changes to the competitive landscape resulting from such legislation or regulation; the impact of regulatory, investigative and legal proceedings and legal compliance risks; government infrastructure projects (such as highway construction) that impact our capital expenditures; continued reductions in switched access revenues as a result of regulation, competition or technology substitutions; our ability to effectively manage service quality in the states in which we operate and meet mandated service quality metrics; the effects of changes in income tax rates, tax laws, regulations or rulings, or federal or state tax assessments, including the risk that such changes may benefit our competitors more than us, as well as potential future decreases in the value of our deferred tax assets; the effects of changes in accounting policies or practices, including potential future impairment charges with respect to our intangible assets or additional losses on assets held for sale; the effects of increased medical expenses and pension and postemployment expenses; our ability to successfully renegotiate union contracts; changes in pension plan assumptions, interest rates, discount rates, regulatory rules and/or the value of our pension plan assets, which could require us to make increased contributions to the pension plan in 2020 and beyond; the effects of weak economic conditions and market disruptions, including the impact of the ongoing COVID-19 pandemic; risks arising from the delisting of our common stock from the Nasdaq Global Select Market; and the risks and other factors contained in Frontier’s filings with the U.S. Securities and Exchange Commission, including our most recent report on Form 10-K and our Form 10-Q for the quarter ended June 30, 2020. These risks and uncertainties may cause actual future results to be materially different than those expressed in such forward-looking statements. Frontier has no obligation to update or revise these forward-looking statements and does not undertake to do so. 2

Non-GAAP Financial Measures Frontier uses certain non-GAAP financial measures in evaluating its performance, including EBITDA, EBITDA margin, Adjusted EBITDA, Adjusted EBITDA margin, operating free cash flow, and adjusted operating expenses, each of which is described below. Management uses these non-GAAP financial measures internally to (i) assist in analyzing Frontier's underlying financial performance from period to period, (ii) analyze and evaluate strategic and operational decisions, (iii) establish criteria for compensation decisions, and (iv) assist in the understanding of Frontier's ability to generate cash flow and, as a result, to plan for future capital and operational decisions. Management believes that the presentation of these non-GAAP financial measures provides useful information to investors regarding Frontier’s financial condition and results of operations because these measures, when used in conjunction with related GAAP financial measures (i) provide a more comprehensive view of Frontier’s core operations and ability to generate cash flow, (ii) provide investors with the financial analytical framework upon which management bases financial, operational, compensation, and planning decisions and (iii) present measurements that investors and rating agencies have indicated to management are useful to them in assessing Frontier and its results of operations. A reconciliation of these measures to the most comparable financial measures calculated and presented in accordance with GAAP is included in the accompanying tables. These non-GAAP financial measures are not measures of financial performance or liquidity under GAAP, nor are they alternatives to GAAP measures and they may not be comparable to similarly titled measures of other companies. EBITDA is defined as net income (loss) less income tax expense (benefit), interest expense, investment and other income (loss), pension settlement costs, gains/losses on extinguishment of debt, and depreciation and amortization. EBITDA margin is calculated by dividing EBITDA by total revenue. Adjusted EBITDA is defined as EBITDA, as described above, adjusted to exclude, certain pension/OPEB expenses, restructuring costs and other charges, stock-based compensation expense, goodwill impairment charges, and certain other non-recurring items. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by total revenue. Management uses EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA margin to assist it in comparing performance from period to period and as measures of operational performance. Management believes that these non-GAAP measures provide useful information for investors in evaluating Frontier’s operational performance from period to period because they exclude depreciation and amortization expenses related to investments made in prior periods and are determined without regard to capital structure or investment activities. By excluding capital expenditures, debt repayments and dividends, among other factors, these non-GAAP financial measures have certain shortcomings. Management compensates for these shortcomings by utilizing these non-GAAP financial measures in conjunction with the comparable GAAP financial measures. Adjusted net income (loss) attributable to Frontier common shareholders is defined as net income (loss) attributable to Frontier common shareholders and excludes restructuring costs and other charges, pension settlement costs, goodwill impairment charges, certain income tax items and the income tax effect of these items, and certain other non-recurring items. Adjusting for these items allows investors to better understand and analyze Frontier’s financial performance over the periods presented. Management defines operating free cash flow, a non-GAAP measure, as net cash from operating activities less capital expenditures. Management uses operating free cash flow to assist it in comparing liquidity from period to period and to obtain a more comprehensive view of Frontier’s core operations and ability to generate cash flow. Management believes that this non-GAAP measure is useful to investors in evaluating cash available to service debt. This non-GAAP financial measure has certain shortcomings; it does not represent the residual cash flow available for discretionary expenditures, as items such as taxes, pension and OPEB costs, interest expense, and debt repayments are not deducted in determining such measure. Management compensates for these shortcomings by utilizing this non-GAAP financial measure in conjunction with the comparable GAAP financial measure. Adjusted operating expenses is defined as operating expenses adjusted to exclude depreciation and amortization, restructuring and other charges, goodwill impairment charges, certain pension/OPEB expenses, stock-based compensation expense, and certain other non-recurring items. Investors have indicated that this non-GAAP measure is useful in evaluating Frontier’s performance. Projected GAAP financial measures are not provided herein because such figures are not available on a forward-looking basis and reconciliations of projected non-GAAP financial measures are not provided because they could not be derived without unreasonable effort.The information in this presentation should be read in conjunction with the financial statements and footnotes contained in Frontier’s documents filed with the U.S. Securities and Exchange Commission. 3

Key Potential Future Network Improvement Opportunities (Outside of Brownfield FTTH Build)~3 million copper locations with low speeds can be upgraded to 20Mbps+ at an average cost of $100 per location (subject to location by location assessment; some locations may overlap with the brownfield FTTH opportunity in which case only one upgrade type may be chosen)Remaining ~100k fiber locations can be upgraded to 1G at an average cost of $80 per locationThe reliability of ~100k copper locations with low speeds can be improved materially 3 million, or ~20%, of ~14 million broadband capable homes are passed with fiber today, with ample opportunity to upgrade FTR’s existing fiber and copper network to improve product capabilities, enhance customer satisfaction, reduce churn, and attract new customers Network: Other Opportunities Outside FTTH Builds 20

Product: Frontier Data-First Strategy To create long-term value and add profitable business, the focus is on creating a higher performance, data-driven product suite and migrating away from legacy products and video Move Towards Profitable Data-Driven Strategy Transition Away from Legacy & Video Video / Triple Play Pivot away from video and triple play sales due to low-margins and high customer acquisition costs Video market under intense competition from OTT players (demand for which bolsters broadband)Offer OTT TV services as an alternative to traditional video Manage Voice Decline Manage TDM voice declinesDevelop more VoIP and UCaaS productsTreat as add-ons for data customers Network Upgrades 3 million copper homes can be upgraded to 20Mbps97% of fiber homes are 1G capable, with ~100K fiber locations that can be upgraded from DSL speeds to 1GBrownfield FTTH Commercial & Wholesale Prioritize ethernet and strategic product salesRamp up enterprise sales and account management force with new structure 21 Products Simplify broadband product offerings and packages

Frontier continues to execute its video strategy of achieving savings by renegotiating contracts and dropping channels; in June 2020, Frontier renegotiated its contract with HBO, lowering content costsFrontier also continues to decrease new gross adds by pausing marketing and sales on video products (recent declines have also been partially influenced by inability to enter homes due to COVID). We are currently evaluating how to profitably participate in the video product marketGross Margin contribution per video sub increased by roughly $3 from Q2 2019 to Q2 2020 Product: Consumer Video Strategy FiOS Video: FiOS Video Revenue less Content Costs per Video Sub Fiber BB vs Fios Video GA Mix 22 Dropped STARZ in Q1‘20, achieving ~$3.6M in quarterly run rate EBITDA benefit net of churnHBO contract was renegotiated in Q2’20, achieving ~$3M per quarter in net EBITDA benefit Content costs regularly raised at the beginning of each year Note: Figures are for Remaining Properties FOX regional sports networks was dropped in early September, achieving ~$9.0M - $10.5M in quarterly net EBITDA benefit Video GAs significantly impacted in Q2 ’20 by a pause on marketing and sales and our inability to enter people’s homes due to COVID FiOS Video GAs

Customer Service / Churn: Fiber Broadband Net Adds Continued initiatives focused on soft-landing promo roll-offs and customer service improvements continued to drive down churn in Q2 ‘20Frontier previously was unable to offer high speed packages to fiber customers for a period during COVID, but that has been resolved via a technology solution Consumer Fiber Broadband Quarterly Net Adds 23 Consumer Fiber Broadband Avg. Monthly Churn Rate Churn reduction continued through Q2‘20, driven by soft-landing promo-roll offs, customer service improvements, and the impact COVID-19 Note: Figures are for Remaining Properties Unable to offer 500Mbps and 1G installs for a period during Q2 ‘20, but this was fixed via a technology solution

COVID-19 Impact Update Operational Learnings and Facts to DateFrontier completed significant 1G fiber upgrades without entering homes, allowing us to improve install efficiency moving forwardThe adjustment to WFH was seamless and appears to have improved productivity to date, translating into an improved customer experienceNon-PaysAfter peaking in April during the height of COVID restrictions and various mandates, such as the FCC Keep America Connected pledge, levels of residential subscribers that are active but not paying have returned to pre-COVID levelsSmall and Medium Business (SMB) non-pays similarly spiked in April – May, and have largely recovered in recent monthsBroadband InstallsWeekly average consumer fiber broadband installs bottomed out during April before rebounding to pre-COVID levelsWeekly average consumer copper broadband installs remained flat through Q2 ’20Commercial installs declined more drastically than their consumer counterpart but are similarly returning to normal levelsBroadband ChurnConsumer broadband has been resilient through the pandemicCommercial churn remained steady through March and April and has improved in recent months Key KPIs show COVID-19’s impact on FTR’s business has been relatively modest to date, with very minor non-payment impact and some improvements in net adds during the pandemic 24
