Full Year 2016 Financial Results Compared to Full Year 2015

Revenues grew $12.4 million, or 1.5%, with increases in residential data and business services revenues more than offsetting decreases in residential video and residential voice revenues. Residential data revenues increased $49.7 million, or 16.9%, due primarily to a rate adjustment taken in the fourth quarter of 2015, an increase in residential data customers of 1.8%, a reduction in package discounting and increased subscriptions to premium tiers. Business services revenues increased $11.6 million, or 13.0%, and total business customer relationships increased 8.7% year-over-year, driven by growth in data and voice services attributable to small and medium-sized businesses and enterprise customers. The decreases in residential video revenues of $37.9 million, or 11.4%, and in residential voice revenues of $7.2 million, or 14.4%, were primarily attributable to residential video and voice customer losses of 12.4% and 12.0%, respectively, during 2016.

Operating expenses (excluding depreciation and amortization) as a percentage of revenues were 37.1% and 38.5% for 2016 and 2015, respectively, and decreased $6.5 million, or 2.1%, year-over-year. The improvements in operating expenses were driven by lower programming costs of $9.9 million associated with the reduction in residential video customers, partially offset by non-programming operating expense increases primarily from higher backbone and Internet connectivity fees of $1.9 million and group insurance of $1.2 million.

Selling, general and administrative expenses as a percentage of revenues were 22.5% and 24.0% for 2016 and 2015, respectively, and decreased $9.2 million, or 4.7%, due primarily to lower customer billing costs following the completion of our billing system conversion of $11.4 million; salaries, wages and benefit costs of $7.3 million and general and workers’ compensation insurance of $2.9 million. These decreases were partially offset by increases in incentive compensation expense of $4.8 million, acquisition-related costs of $4.7 million and marketing expense of $3.2 million.

Other income increased $5.4 million in 2016, reflecting primarily a $4.1 million gain on the sale of a cable system. Interest expense almost doubled with a full year of interest incurred on the Company’s borrowings under its credit facilities compared to six months of interest incurred in 2015.

Net income increased $9.9 million, or 11.1%, to $98.9 million in 2016, compared to $89.0 million in the prior year, resulting primarily from improvements in our operating and selling, general and administrative expenses as a percentage of revenues and the gain from the sale of a cable system partially offset by higher interest and income tax expenses during 2016.

Adjusted EBITDA increased 10.3% to $350.5 million in 2016 compared to $317.7 million in the prior year. Capital expenditures totaled $125.5 million and $166.4 million for 2016 and 2015, respectively. Adjusted EBITDA less capital expenditures was $225.0 million, an increase of $73.7 million, or 48.7%, from the prior year.

Fourth Quarter 2016 Financial Results Compared to Fourth Quarter 2015

Revenues increased $3.3 million, or 1.6%, due primarily to increases in residential data and business services revenues of $10.0 million and $3.3 million, respectively. For the fourth quarter of 2016 and 2015, residential data revenues comprised 42.5% and 38.3% of total revenues and business services revenues comprised 12.9% and 11.4% of total revenues, respectively. The increases in residential data and business services revenues more than offset decreases in residential video and voice revenues of $5.9 million and $2.5 million, respectively, primarily attributable to customer losses year-over-year.

Operating expenses (excluding depreciation and amortization) decreased slightly in the fourth quarter of 2016 and improved as a percentage of revenues at 36.3% compared to 37.0% in the fourth quarter of 2015. The improvements in operating expenses were driven by lower programming costs of $1.4 million associated with the reduction in residential video customers, partially offset by an increase in group insurance costs of $1.2 million.

Selling, general and administrative expenses as a percentage of revenues were 23.5% and 21.9% in the fourth quarter of 2016 and 2015, respectively, and increased $4.2 million, or 9.4%. The increase was primarily attributable to higher marketing expenses of $2.1 million, professional fees of $2.1 million and acquisition-related costs of $1.6 million, partially offset by decreased customer billing costs of $1.3 million.

Net income decreased $1.7 million, or 6.5%, to $24.4 million in the fourth quarter of 2016 compared to $26.1 million in the prior year period. The lower net income in the fourth quarter of 2016 was driven by higher selling, general and administrative expenses and depreciation and amortization expenses partially offset by lower income tax expenses compared to the fourth quarter of 2015.

Adjusted EBITDA was $88.6 million and $88.0 million, and capital expenditures totaled $34.2 million and $67.1 million for the fourth quarter of 2016 and 2015, respectively. Adjusted EBITDA less capital expenditures was $54.4 million, an increase of $33.6 million, or 160.8%, from the prior year period. The Adjusted EBITDA growth year-over-year was affected by the positive net impact of $2.3 million for certain insurance-related benefits and other costs realized in the fourth quarter of 2015. Excluding the net impact of these benefits and costs, Adjusted EBITDA growth would have been 3.4% year-over-year.

Liquidity and Capital Resources

At December 31, 2016, the Company had approximately $138.0 million of cash and cash equivalents on hand, compared to $119.2 million at December 31, 2015. The Company’s debt balance, excluding unamortized debt issuance costs, was $545.3 million and $549.1 million at December 31, 2016 and 2015, respectively. The Company also had $197.2 million available for borrowing under its revolving credit facility as of December 31, 2016. During 2016, the Company repurchased 126,797 shares under its stock repurchase program at an aggregate cost of $56.4 million.

Acquisition of NewWave

In January 2017, the Company announced the acquisition of NewWave for a purchase price of $735 million in cash, subject to customary post-closing adjustments. The Company expects to finance the transaction with $650 million of senior secured loans and cash on hand. The transaction is expected to be completed in the second quarter of 2017.

Other Information

In the first quarter of 2017, the Company changed its accounting estimate related to the capitalization of certain internal labor and related costs associated with construction and customer installation activities.  Historically, the Company did not have adequate information to identify and calculate all of the capitalizable labor and related costs, and therefore these costs were expensed as incurred. In the first quarter of 2017, the Company has implemented systems and processes that allow it to more accurately estimate the amount of directly identifiable labor costs incurred on construction and installation activities.  The Company anticipates that this change in estimate will result in an increase of capitalized labor costs for existing operations in the range of $28 million to $33 million on an annual basis, resulting in an equivalent decrease in expenses and increase in capital expenditures beginning in 2017. The Company estimates that net income will increase in the range of $16 million to $20 million in 2017 as a result of this change, although the net income impact will diminish over the following several years because of additional depreciation. Adjusted EBITDA will increase the same amount as capital expenditures, and Adjusted EBITDA margin will also rise. Adjusted EBITDA less capital expenditures will not be affected by this change in estimate.²

² As noted above, Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted EBITDA less capital expenditures are non-GAAP financial metrics. For more information, refer to the section of this press release entitled “Use of Non-GAAP Financial Metrics.”

Use of Non-GAAP Financial Metrics

The Company uses certain measures that are not defined by generally accepted accounting principles in the United States (“GAAP”) to evaluate various aspects of its business. Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted EBITDA less capital expenditures are non-GAAP financial measures and should be considered in addition to, not as a substitute for, net income, net profit margin or net cash provided by operating activities reported in accordance with GAAP. These terms, as defined by Cable ONE, may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA and Adjusted EBITDA less capital expenditures are reconciled to net income in the Reconciliations of Non-GAAP Measures tables of this press release. Adjusted EBITDA Margin is reconciled to net profit margin in the Reconciliations of Non-GAAP Measures tables of this press release. Adjusted EBITDA less capital expenditures is also reconciled to net cash provided by operating activities in the Reconciliations of Non-GAAP Measures tables of this press release.

“Adjusted EBITDA” is defined as net income plus net interest expense, provision for income taxes, depreciation and amortization, equity- and pre-spin cash-based incentive compensation expense, loss (gain) on deferred compensation, other (income) expense, net, acquisition-related costs, loss on disposal of fixed assets and other unusual operating expenses, as defined in the Reconciliations of Non-GAAP Measures tables of this press release. As such, it eliminates the significant non-cash depreciation and amortization expense that results from the capital-intensive nature of the Company’s business as well as other non-cash or special items and is unaffected by the Company’s capital structure or investment activities. This measure is limited in that it does not reflect the periodic costs of certain capitalized tangible and intangible assets used in generating revenues and the Company’s cash cost of financing. These costs are evaluated through other financial measures.

“Adjusted EBITDA Margin” is defined as Adjusted EBITDA divided by total revenues.

“Adjusted EBITDA less capital expenditures” is calculated as net cash provided by operating activities excluding the impact of capital expenditures, interest expense, provision for income taxes, changes in operating assets and liabilities and other unusual operating expenses, as defined in the Reconciliations of Non-GAAP Measures tables of this press release, when used as a liquidity measure.

The Company uses Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted EBITDA less capital expenditures to assess its performance, and it also uses Adjusted EBITDA less capital expenditures as an indicator of its ability to fund operations and make additional investments with internally-generated funds. In addition, Adjusted EBITDA generally correlates to the leverage ratio calculation under the Company’s credit facilities and outstanding 5.75% senior unsecured notes due 2022 to determine compliance with the covenants contained in the facilities and notes. For the purpose of calculating compliance with leverage covenants, the Company uses a measure similar to Adjusted EBITDA, as presented. Adjusted EBITDA and capital expenditures are also significant performance measures used by the Company in its annual incentive compensation program. Adjusted EBITDA does not take into account cash used for mandatory debt service requirements or other non-discretionary expenditures, and thus does not represent residual funds available for discretionary uses.

The Company believes Adjusted EBITDA and Adjusted EBITDA Margin are useful to investors in evaluating the operating performance of the Company. The Company believes that Adjusted EBITDA less capital expenditures is useful to investors as it shows the Company’s performance while taking into account cash outflows for capital expenditures and is one of several indicators of the Company’s ability to service debt, make investments and/or return capital to its shareholders.

Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted EBITDA less capital expenditures and similar measures with similar titles are common measures used by investors, analysts and peers to compare performance in the Company’s industry, although the Company’s measures of Adjusted EBITDA, Adjusted EBITDA Margin and Adjusted EBITDA less capital expenditures may not be directly comparable to similarly titled measures reported by other companies.
