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 both the conditions in the plan and 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 Frontier and the interests of various constituents; risks and uncertainties associated with the Restructuring, including our ability to satisfy the conditions precedent for effectiveness of and successfully consummate the Restructuring; our ability to comply with the restrictions imposed by covenants in our debtor-in-possession financing and expected to be imposed by our exit financing; the length of time that Frontier 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 Frontier’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; declines in Adjusted EBITDA relative to historical levels that we are unable to offset through potential EBITDA enhancements; 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; changes to our board of directors and management team upon emergence from bankruptcy or in anticipation of emergence, and 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 expiration of CAF II funding and future RDOF funding and participation in the next round of the RDOF program; our ability to meet our CAF II and RDOF obligations and the risk of penalties or obligations to return certain CAF II and/or RDOF 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; adverse changes in economic, political and market conditions in the areas that we serve, the U.S. and globally, including but not limited to, changes resulting from epidemics, pandemics and outbreaks of contagious diseases, including the COVID-19 pandemic, or other adverse public health developments; potential adverse impacts of the COVID-19 pandemic on our business and operations, including potential disruptions to the work of our employees arising from health and safety measures such as social distancing and working remotely, our ability to effectively manage increased demand on our network, our ability to maintain relationships with our current or prospective customers and vendors as well as their abilities to perform under current or proposed arrangements with us, and stress on our supply chain; trading price and volatility of our common stock, risks related to 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 the cancellation of our common stock contemplated by the Plan. 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.

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), expense, investment and other (loss), pension settlement  interest income costs,  gains/losses on extinguishment of debt,  reorganization items 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 restructuring costs and other pension settlement costs,  excludes charges, 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.
