Frontier Communications Reports 2017 Second Quarter Results

Norwalk, Conn., August 1, 2017 – Frontier Communications Corporation (NASDAQ:FTR) today reported financial results for the second quarter ended June 30, 2017.

“We were pleased with the progress we made during the second quarter as we executed well on a number of key initiatives stabilizing operations,” said Dan McCarthy, President and CEO. “In particular, we improved churn in our California, Texas and Florida (CTF) market, saw progress in our commercial business, and continued to reduce costs, which resulted in increased adjusted EBITDA margins². Our commitment to enhancing the customer experience, further reducing churn, generating cash flow, and improving the balance sheet positions the Company to further stabilize the business and grow longer-term.”

Consolidated Results

Consolidated revenues for the second quarter were $2.3 billion. Within consolidated revenue, consumer revenue was $1.12 billion, commercial revenue was $982 million and regulatory revenue was $198 million.    

Net loss for the second quarter of 2017 was $662 million, principally driven by a $532 million (after tax) goodwill impairment charge. Net loss attributable to common shares was $715 million or $9.21 per diluted share (based on 78 million weighted average diluted shares outstanding³), again driven

principally by the $532 million ($6.82 per diluted share) goodwill impairment charge. Adjusted EBITDA⁴ totaled $906 million or 39.3% of total revenue, an increase from 39.2% in the first quarter of 2017.

Net cash provided from operating activities was $529 million for the second quarter of 2017. Adjusted free cash flow⁵ was $205 million for the second quarter. Frontier’s dividend payout ratio⁶ was 23% in the second quarter, down from 71% in the first quarter of 2017.

Capital Structure

In order to reduce interest expense and extend maturities, Frontier obtained a $1.5 billion senior secured term loan B facility (Term Loan B) during the second quarter. The Term Loan B matures on June 15, 2024⁷. As of June 30, 2017, the interest rate for this facility was LIBOR plus 3.75%. The determination of interest rates for the Term Loan B is based on margins over the Base Rate (as defined in the credit agreement) or LIBOR, at the election of Frontier.

In June 2017, Frontier used cash proceeds from the Term Loan B offering to retire $763 million of 8.875% Notes due 2020 and $527 million of 8.500% Notes due 2020.

Frontier’s leverage ratio⁸ was 4.20 for the second quarter of 2017 compared to 4.39 in the first quarter of 2017. The Company remains committed to deleveraging the business.

Guidance

For the full year 2017, Frontier’s guidance is the following:

Non-GAAP Measures

Frontier uses certain non-GAAP financial measures in evaluating its performance, including EBITDA, EBITDA margin, adjusted EBITDA, adjusted EBITDA margin, free cash flow, adjusted free cash flow, adjusted operating expenses, dividend payout ratio and leverage ratio, 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. We believe that the presentation of these non-GAAP financial measures provides useful information to investors regarding our 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 our 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, losses on extinguishment of debt and depreciation and amortization. EBITDA margin is calculated by dividing EBITDA by total revenues.

Adjusted EBITDA is defined as EBITDA, as described above, adjusted to exclude acquisition and integration costs, non-cash pension/OPEB costs (including pension settlement costs), restructuring costs and other charges and goodwill impairment charges. Adjusted EBITDA margin is calculated by dividing adjusted EBITDA by total revenues.

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. We believe that these non-GAAP measures provide useful information for investors in evaluating our 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, 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 acquisition and integration costs, restructuring costs and other charges, pension settlement costs, goodwill impairment charges, certain income tax items and the income tax effect of these items. Adjustments have also been made to exclude the financing costs and related income tax effects associated with the Verizon Transaction, including interest expense and preferred dividends prior to our ownership of the CTF Operations. Adjusting for these items allows investors to better understand and analyze our financial performance over the periods presented.

Free Cash Flow, as used by management in the operation of its business, is defined as net cash provided from operating activities less capital expenditures for business operations and preferred dividends. In determining free cash flow, further adjustments are made to add back acquisition and integration costs, and interest expense on commitment fees, which provides a better comparison of our core operations from period to period. Changes in working capital accounts are excluded from this calculation due to seasonality and specific timing of cash receipts and disbursements between various reporting periods.

Adjusted Free Cash Flow is defined as free cash flow, as described above and adding back dividends paid and interest expense on incremental debt, prior to our ownership of the CTF Operations, on preferred stock issued and debt incurred to finance the Verizon Acquisition.

Management uses Free Cash Flow and Adjusted Free Cash Flow to assist it in comparing performance and liquidity from period to period and to obtain a more comprehensive view of our core operations and ability to generate cash flow. We believe that these non-GAAP measures are useful to investors in evaluating cash available to service debt and pay dividends. In addition, we believe that Adjusted Free Cash Flow provides a useful comparison from period to period because it excludes the impact of financing raised in connection with the Verizon Acquisition during periods prior to our ownership of the CTF Operations. These non-GAAP financial measures have certain shortcomings; they do not represent the residual cash flow available for discretionary expenditures,

since items such as debt repayments, changes in working capital and common stock dividends are not deducted in determining such measures. Management compensates for these shortcomings by utilizing these non-GAAP financial measures in conjunction with the comparable GAAP financial measures.

Leverage Ratio is the measure of leverage specified in Frontier’s credit facilities: “as of the last day of any fiscal quarter, the ratio of (a) Total Indebtedness as of such day to (b) Consolidated EBITDA for the four consecutive fiscal quarters ending on such day.” The definitions of Total Indebtedness and Consolidated EBITDA are as set forth in the First Amended and Restated Credit Agreement, dated as of February 27, 2017, among Frontier Communications Corporation, JPMorgan Chase, N.A., as Administrative Agent, and the other lenders party thereto, filed as Exhibit 10 to Frontier’s Form 8-K, filed with the SEC on February 28, 2017.

Dividend Payout Ratio is calculated by dividing the dividends paid on common stock (as adjusted) by adjusted free cash flow. Dividends paid on common stock has been adjusted to exclude dividends paid on common stock issued in June 2015, from the date of issuance until April 1, 2016, when the proceeds of the issuance were used in the Verizon acquisition that generated adjusted free cash flow from that date. Management uses the dividend payout ratio as a metric to indicate how much money Frontier is returning to our shareholders. We have made adjustments to exclude the impact of financing raised in connection with the Verizon Acquisition during periods prior to our ownership of the CTF Operations, which we believe provides a useful comparison from period to period.

Adjusted Operating Expenses is defined as operating expenses adjusted to exclude depreciation and amortization, acquisition and integration costs, goodwill impairment charges, non-cash pension/OPEB costs (including pension settlement costs) and restructuring costs and other charges. Investors have indicated that this non-GAAP measure is useful in evaluating Frontier’s performance.

The information in this press release should be read in conjunction with the financial statements and footnotes contained in our documents filed with the U.S. Securities and Exchange Commission.
