The Company was not in compliance with the bank-defined adjusted EBITDA covenant related to the credit facility as of June 30, 2017, however, a waiver has been obtained. Additionally, the Company has entered into an amendment to its credit facility with terms and covenants intended to align with completing the acquisition by Sizmek Inc. that was announced on July 18, 2017, or to pay down the remaining balance by October 31, 2017.

Employee Headcount: 726 as of June 30, 2017, down from 899 in the second quarter of 2016.

Financial Outlook for the Third Quarter of 2017

For the third quarter of 2017, the Company expects:

- Non-GAAP net revenue between $35.0 million and $40.0 million.

- Non-GAAP Adjusted EBITDA between negative $10.0 million and negative $5.0 million.

The Company does not reconcile its forward-looking non-GAAP financial measures, net revenue and adjusted EBITDA, to the corresponding GAAP measures due to the high variability and difficulty in making accurate forecasts and projections in respect to the interplay between revenue and the corresponding margins. Our Media Services and Platform Solutions have different media margins and the pace of the transition of some of our business from Media Services to Platform Solutions, the pace of adoption, or activation of existing Platform Solutions customers, and the corresponding future margins cannot be reasonably predicted. The GAAP measure net income includes stock-based compensation expense that is impacted by future hiring and retention needs, and the future share price of Rocket Fuel’s stock. Similarly, restructuring charges, which we exclude from our non-GAAP measure adjusted EBITDA, are impacted by future decisions and by actions involving our facilities that are difficult to predict. The actual amounts of these excluded items will have a significant impact on the Company’s GAAP net income. Accordingly, reconciliations of these two forward-looking non-GAAP financial measures to the corresponding GAAP measures are not available without unreasonable effort.

Conference Call, Webcast and Related Information

As a result of the announcement on July 18, 2017, regarding Rocket Fuel’s entry into a definitive agreement to be acquired by Sizmek Inc., Rocket Fuel will not be hosting a conference call to discuss its second quarter 2017 financial results.

Use of Non-GAAP Measures

We provide information relating to non-GAAP spend, non-GAAP net revenue, non-GAAP adjusted EBITDA, non-GAAP adjusted net income (loss), non-GAAP operating expenses and non-GAAP free cash flow, which are financial measures that have not been prepared in accordance with generally accepted accounting principles in the United States ("GAAP"). These non-GAAP financial measures have been included in this press release because they are measures used by our management and board of directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget, and to develop short- and long-term operational plans.

We define non-GAAP spend as GAAP revenue plus platform media costs for a portion of our sales arrangements (customers with revenue recognized on a net basis per GAAP). Media costs consist of costs for advertising impressions we purchase from advertising exchanges or other third parties. A limitation of non-GAAP spend is that it is a measure designed for internal purposes to assess market share and scale, and to plan for optimal levels of support for our clients that may be unique to Rocket Fuel. This may not enhance the comparability of Rocket Fuel’s results to other companies in the same industry that have similar business arrangements but present the impact of media costs differently. Our management compensates for this limitation by also considering the comparable GAAP financial measures of revenue, media costs and other costs of revenue.

We define non-GAAP net revenue as GAAP revenue less media costs. A limitation of non-GAAP net revenue is that it is a measure designed for internal purposes that may be unique to Rocket Fuel and may not enhance the comparability of Rocket Fuel’s results to other companies in the same industry that have similar business arrangements but present the impact of media costs differently. Our management compensates for this limitation by also considering the comparable GAAP financial measures of revenue, media costs and other costs of revenue.

We define non-GAAP adjusted EBITDA as GAAP net income (loss) before interest expense, other income (expense), net, income tax provision (benefit), depreciation and amortization expense (including amortization of capitalized software development expenses), stock-based compensation expense and related payroll taxes, acquisition and restructuring related expenses, and impairment charges. Non-GAAP adjusted EBITDA has a number of limitations, including the following: although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future and non-GAAP adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; non-GAAP adjusted EBITDA is often considered an approximation of operating cash flow, but in our case excludes software development costs capitalized in a current period and excludes those costs as they are amortized over future periods; non-GAAP adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; non-GAAP adjusted EBITDA does not consider the potentially dilutive impact of equity-based compensation; non-GAAP adjusted EBITDA does not reflect acquisition and restructuring related expenses, the expenses capitalized for internal-use software, tax and interest expenses that may represent payments reducing the cash available to us; and other companies, including those in our industry, may calculate non-GAAP adjusted EBITDA differently, which reduces its usefulness as a comparative measure. Because of these limitations, our management considers non-GAAP adjusted EBITDA alongside other financial performance measures, including cash flow metrics, net income (loss) and our other GAAP results.

We define non-GAAP adjusted net income (loss) as GAAP net income (loss) excluding stock-based compensation expense, amortization of intangible assets, impairment charges, acquisition and restructuring related expenses and the estimated tax impact of the foregoing items. A limitation of non-GAAP adjusted net income (loss) is that it is a measure that may be unique to Rocket Fuel and may not enhance the comparability of Rocket Fuel’s results to other companies in the same industry that define adjusted net income (loss) differently. This measure may also exclude expenses that may have a material impact on Rocket Fuel’s reported financial results. Our management compensates for these limitations by also considering the comparable GAAP financial measure of net income (loss).

We define non-GAAP operating expenses as GAAP total costs and expenses less media costs, depreciation and amortization expense (including amortization of capitalized software development costs), impairment charges, stock-based compensation expense and related payroll taxes, and acquisition and restructuring related expense. Non-GAAP operating expenses has a number of limitations, including the following: although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future and this measure does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; non-GAAP operating expenses is often considered an approximation of operating cash flow, but in our case excludes software development costs capitalized in a current period and excludes those costs as they are amortized over future periods; non-GAAP operating expenses does not reflect changes in, or cash requirements for, our working capital needs; non-GAAP operating expenses does not consider the potentially dilutive impact of equity-based compensation; non-GAAP operating expenses does not reflect acquisition and restructuring related expenses, the expenses capitalized for internal-use software, tax and interest expenses that may represent payments reducing the cash available to us; and other companies, including those in our industry, may calculate non-GAAP operating expenses differently, which reduces its usefulness as a comparative measure. Because of these limitations, our management considers non-GAAP operating expenses alongside other financial performance measures, including total expenses, cash from operating activities and our other GAAP results.

In addition, we provide information about our non-GAAP free cash flow. We define non-GAAP free cash flow as the net cash provided by (or used in) operating activities less the cash used for purchases of property, equipment and software and for capitalized internal-use software development costs. A limitation of free cash flow is that it may be unique to Rocket Fuel and may not enhance the comparability of Rocket Fuel’s results to other companies in the same industry that define free cash flow differently from us. This measure also does not represent the residual cash flow available to us for discretionary expenditures or investments because we have mandatory capital leases and debt service requirements that may have a material impact on Rocket Fuel’s liquidity. Our management compensates for these limitations by also considering the comparable GAAP financial measure of net cash provided by (or used in) operating activities.

For a reconciliation of non-GAAP financial measures to the nearest comparable GAAP financial measures, see “Reconciliation from GAAP Revenue to Non-GAAP Spend,” “Reconciliation from GAAP Revenue to Non-GAAP Net Revenue,” “Reconciliation from GAAP Net Income (Loss) to Non-GAAP Adjusted EBITDA,” “Reconciliation from GAAP Net Income (Loss) to Non-GAAP Adjusted Net Income (Loss)”, “Reconciliation from GAAP Total Cost and Expenses to Non-GAAP Operating Expenses" and “Reconciliation from GAAP Net Cash Provided by (Used in) Operating Activities to Non-GAAP Free Cash Flow" included in this press release.

These non-GAAP financial measures are not intended to be considered in isolation from, as substitutes for, or as superior to, the corresponding financial measures prepared in accordance with GAAP.
