"We delivered a record third quarter across revenue, margins, and profitability, driven by the strength of our Performance TV platform,” said Mark Douglas, CEO of MNTN. “We’re leading one of the biggest shifts in advertising, transforming Connected TV into a true performance channel. MNTN provides small and midsize businesses tools to succeed on TV and with 97% of brands on MNTN being first time advertisers - it's proof that we're opening television to a whole new generation of advertisers.”

Non-GAAP Financial Measures

We use certain non-GAAP financial measures, including EBITDA and Adjusted EBITDA in this press release. EBITDA is defined as net loss adjusted to exclude depreciation and amortization expense, interest income (expense), net, and income tax expense (benefit). Adjusted EBITDA is defined as net loss adjusted to exclude depreciation and amortization expense, interest income (expense), net, and income tax expense (benefit), as further adjusted to exclude stock-based compensation expense, fair value adjustments on outstanding warrants, contingent liabilities, embedded derivatives, and convertible debt, acquisition costs including legal costs associated with prior acquisitions, legal settlements and loss on debt extinguishment, which are items that we believe are not indicative of our core operating performance.

Adjusted EBITDA is a supplemental measure of our performance, is not defined by or presented in accordance with GAAP and should not be considered in isolation or as an alternative to net loss, net loss margin or any other performance measure prepared in accordance with GAAP. Adjusted EBITDA is presented because we believe it provides useful supplemental information to investors, analysts, and rating agencies regarding our operating performance and our capacity to incur and service debt and is frequently used by these parties in evaluating companies in our industry. By presenting Adjusted EBITDA we provide a basis for comparison of our business operations between periods by excluding items that we do not believe are indicative of our core operating performance. We believe that investors’ understanding of our performance is enhanced by including this non-GAAP financial measure as a reasonable basis for comparing our ongoing results of operations. Additionally, management uses Adjusted EBITDA as a supplemental measure of our performance because it assists us in comparing the operating performance of our business on a consistent basis between periods, as described above.

Although we use Adjusted EBITDA as described above, Adjusted EBITDA has significant limitations as analytical tools. Some of these limitations include:

• such measure does not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments;
• such measure does not reflect changes in, or cash requirements for, our working capital needs;
• such measure does not reflect the interest expense, or the cash requirements necessary to service interest or principal payments on our debt;
• such measure does not reflect our tax expense or the cash requirements to pay our taxes;
• although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future and such measure does not reflect any cash requirements for such replacements; and
• other companies in our industry may calculate such measure differently than we do, thereby further limiting its usefulness as comparative measures.

Due to these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business. We compensate for these limitations by relying primarily on our GAAP results and using this non-GAAP measure only supplementally. As noted in the table below, Adjusted EBITDA includes adjustments for items that we believe are not indicative of our core operating performance. It is reasonable to expect that these items will occur in future periods. However, we believe these adjustments are appropriate because the amounts recognized can vary significantly from period-to-period, do not directly relate to the ongoing operations of our business and complicate comparisons of our internal operating results between periods and with the operating results of other companies over time. Each of the normal recurring adjustments and other adjustments described in this paragraph and in the reconciliation table below help management with a measure of our core operating performance over time by removing items that are not related to day-to-day operations. Nevertheless, because of the limitations described above, management does not view Adjusted EBITDA in isolation and also uses other measures, such as revenue, operating loss and net loss, to measure operating performance.

Set forth below are reconciliations of the Company’s most directly comparable financial measures calculated in accordance with GAAP to these non-GAAP financial measures.

A reconciliation of the Company’s non-GAAP financial measure guidance to the most directly comparable GAAP financial measure cannot be provided without unreasonable efforts and is not provided herein because of the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation and certain other items reflected in our reconciliation of historical non-GAAP financial measures, the amounts of which could be material.
