Rubicon Project Reports Fourth Quarter and Full Year 2017 Results PDF Version Company Announces Significant Cost Reductions LOS ANGELES, March 14, 2018 (GLOBE NEWSWIRE) -- Rubicon Project(NYSE:RUBI), the global exchange for advertising, today reported its results of operations for the fourth quarter and year ended December 31, 2017. Recent Highlights: Total annualized spending reduced by $44 million or 23% on a forward run rate basis. This compares Q4 2017 annualized run rate of adjusted EBITDA operating expenses and capital expenditures to the post reduction run rate. Reduction includes elimination of 100 positions, $20 million reduction to capital expenditures, and implementation of other operating efficiencies in 2018. Double digit year over year advertising spend growth since early February. Take rate remaining stable since November 1, 2017 elimination of the Company's buyer fees. Company expects to be adjusted EBITDA positive in Q4 of 2018. Improved auction dynamics by implementing a default first price auction in header bidding transactions and launching our Estimated Market Rate ("EMR") tool for buyers. Revenue for the fourth quarter 2017 was $31.4 million, compared to $72.7 million for the fourth quarter of 2016; Non-GAAP net revenue(1) was $31.4 million, compared to $66.9 million for the fourth quarter of 2016. Net loss for the fourth quarter 2017 was $23.8 million, or diluted loss per share of $0.48, compared to net loss of $21.2 million, or diluted loss per share of $0.44 for the fourth quarter of 2016. Included in the net loss for the fourth quarter of 2017 was an impairment of intangible assets expense of $4.6 million. Adjusted EBITDA loss(1) for Q4 2017 was $6.2 million, compared to Adjusted EBITDA of $21.7 million for the fourth quarter of 2016. Non-GAAP loss per share(1) was $0.28 for the fourth quarter of 2017, compared to $0.37 in non-GAAP earnings per share for the fourth quarter of 2016. “We made significant strides to strengthen our competitive and financial position during and after the fourth quarter,” said Michael G. Barrett, President and CEO of Rubicon Project. "As our industry moves through a heightened consolidation phase, we continue to lead in transparency, trust, support and technology, all with extremely attractive pricing, to win business with buyers and deliver meaningful revenue growth for our publishers. 2017 was a year we invested heavily to position the company for growth and in 2018 we have now taken significant steps to reduce our operating costs and capex. The result of recent double digit ad spend growth, combined with today's cost reductions are intended to put us on strong financial footing and make us adjusted EBITDA positive in Q4 of 2018.” Fourth Quarter and Full Year 2017 Results Summary (in millions, except per share amounts and percentages) Three Months Ended Year Ended December 31, 2017 December 31, 2016 Change Favorable/(Unfavorable) December 31, 2017 December 31, 2016 Change Favorable/(Unfavorable) Revenue $ 31.4 $ 72.7 (57 )% $ 155.5 $ 278.2 (44 )% Advertising spend(1) $ 246.3 $ 277.1 (11 )% $ 837.2 $ 1,025.8 (18 %) Non-GAAP net revenue(1) $ 31.4 $ 66.9 (53 )% $ 154.9 $ 256.1 (40 %) Take rate(3) 12.8 % 24.1 % (11 ppt) 18.5 % 25.0 % (7 ppt) Net loss $ (23.8 ) $ (21.2 ) (12 )% $ (154.8 ) $ (18.1 ) NM Adjusted EBITDA(1) $ (6.2 ) $ 21.7 NM $ (4.4 ) $ 70.9 NM Adjusted EBITDA margin(2) (20 %) 32 % NM (3 %) 28 % NM Basic net loss per share $ (0.48 ) $ (0.44 ) (9 )% $ (3.17 ) $ (0.39 ) NM Diluted loss per share $ (0.48 ) $ (0.44 ) (9 )% $ (3.17 ) $ (0.39 ) NM Non-GAAP earnings (loss) per share(1) $ (0.28 ) $ 0.37 NM $ (0.68 ) $ 1.07 NM Definitions: NM Not meaningful. (1) Advertising spend, non-GAAP net revenue, Adjusted EBITDA and non-GAAP earnings (loss) per share are non-GAAP financial measures. Please see the discussion in the section called "Non-GAAP Financial Measures" and the reconciliations included at the end of this press release. (2) Adjusted EBITDA margin is calculated as Adjusted EBITDA divided by non-GAAP net revenue. Reconciliations for both net loss to Adjusted EBITDA and revenue to non-GAAP net revenue are included at the end of this press release. For further discussion, please see "Non-GAAP Financial Measures." (3) Take rate is an operational performance measure calculated as revenue (or for periods in which we have revenue reported on a gross basis, as non-GAAP net revenue) divided by advertising spend. The decline in our take rate compared to the 2016 periods is due to the reduction of our buyer fees during 2017, culminating in their elimination on November 1. Reconciliations for revenue to both advertising spend and non-GAAP net revenue are included at the end of this press release. For further discussion, please see "Non-GAAP Financial Measures." We review take rate for internal management purposes to assess the development of our marketplace with buyers and sellers. Our take rate (and our fees, which drive take rate) can be affected by a variety of factors, including the terms of our arrangements with buyers and sellers active on our platform in a particular period, the scale of a buyer's or seller's activity on our platform, mix of inventory or transaction types, the implementation of new products, platforms and solution features, auction dynamics, negotiations with clients, header bidding, competitive factors, and the overall development of the digital advertising ecosystem.

These forward-looking statements represent our estimates and assumptions only as of the date they are made. Unless required by federal securities laws, we assume no obligation to update any of these forward-looking statements, or to update the reasons actual results could differ materially from those anticipated, to reflect circumstances or events that occur after the statements are made. Without limiting the foregoing, any guidance we may provide will generally be given only in connection with quarterly and annual earnings announcements, without interim updates, and we may appear at industry conferences or make other public statements without disclosing material nonpublic information in our possession. Given these uncertainties, investors should not place undue reliance on these forward-looking statements. Investors should read this press release and the documents that we reference in this press release and have filed or will file with the SEC completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. Non-GAAP Financial Measures: This press release includes information relating to advertising spend, non-GAAP net revenue, Adjusted EBITDA, non-GAAP net income, and non-GAAP earnings per share, which are financial measures that have not been prepared in accordance with GAAP. These non-GAAP financial measures are used by our management and board of directors, in addition to our GAAP results, to understand and evaluate our performance and trends, to prepare and approve our annual budget, and to develop short- and long-term plans and performance objectives. Management believes that these non-GAAP financial measures provide useful information about our core results and thus are appropriate to enhance the overall understanding of our past performance and our prospects for the future. 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. You are encouraged to evaluate these adjustments, and review the reconciliation of these non-GAAP financial measures to their most comparable GAAP measures, and the reasons we consider them appropriate. It is important to note that the particular items we exclude from, or include in, our non-GAAP financial measures may differ from the items excluded from, or included in, similar non-GAAP financial measures used by other companies. See "Reconciliation of revenue to advertising spend and revenue to non-GAAP net revenue," "Reconciliation of net loss to Adjusted EBITDA," "Reconciliation of net loss to non-GAAP net income" and "Reconciliation of GAAP EPS to non-GAAP EPS" included as part of this press release. We define advertising spend as the buyer spending on advertising transacted on our platform. Advertising spend does not represent revenue reported on a GAAP basis. Tracking our advertising spend allows us to compare our results to the results of companies that report all spending transacted on their platforms as GAAP revenue on a gross basis. We also use advertising spend for internal management purposes to assess market share of total advertising spending. Our advertising spend may be influenced by demand for our services, the volume and characteristics of paid impressions, average CPM, and other factors such as changes in the market, our execution of the business, and competition. Advertising spend may fluctuate due to seasonality and increases or decreases in average CPM and paid impressions. In addition, we generally experience higher advertising spend during the fourth quarter of a given year resulting from higher advertising budgets by advertisers and more bidding activity on our platform, which may drive higher volumes of paid impressions or average CPM. Growth in our advertising spend slowed significantly in 2016 for various reasons, including shift of spending on digital advertising from desktop, which represents the majority of our business to mobile, our delay in embracing header bidding, and absorption by competitors, principally Google and Facebook, of an increasing share of growth in spending on digital advertising. We define non-GAAP net revenue as GAAP revenue less amounts we pay sellers that are included within cost of revenue for the portion of our revenue reported on a gross basis. Non-GAAP net revenue would represent our revenue if we were to record all of our revenue on a net basis. Non-GAAP net revenue does not represent revenue reported on a GAAP basis. Non-GAAP net revenue is one useful measure in assessing the performance of our business in periods for which our revenue includes revenue reported on a gross basis, because it shows the operating results of our business on a consistent basis without the effect of differing revenue reporting (gross vs. net) that we apply under GAAP across different types of transactions, and facilitates comparison of our results to the results of companies that report all of their revenue on a net basis. A potential limitation of non-GAAP net revenue is that other companies may define non-GAAP net revenue differently, which may make comparisons difficult. Non-GAAP net revenue is influenced by demand for our services, the volume and characteristics of advertising spend, and our take rate. The revenue we have reported on a gross basis was associated with our intent marketing business. Because we exited that business in the first quarter of 2017, we do not expect to report any revenue on a gross basis after the first quarter of 2017 unless and until we change our business practices, develop new products, or make an acquisition, in each case with characteristics that require gross reporting. Adjusted EBITDA: We define Adjusted EBITDA as net income (loss) adjusted to exclude stock-based compensation expense, depreciation and amortization, amortization of acquired intangible assets, impairment charges, interest income or expense, and other cash and non-cash based income or expenses that we do not consider indicative of our core operating performance, including, but not limited to foreign exchange gains and losses, acquisition and related items, and provision (benefit) for income taxes. These items may include recurring as well as non-recurring items. These adjustments should not be construed to imply that all of these adjustments or costs are unusual, infrequent or non-recurring. We believe Adjusted EBITDA is useful to investors in evaluating our performance for the following reasons: Adjusted EBITDA is widely used by investors and securities analysts to measure a company’s performance without regard to items such as those we exclude in calculating this measure, which can vary substantially from company to company depending upon their financing, capital structures, and the method by which assets were acquired. Our management uses Adjusted EBITDA in conjunction with GAAP financial measures for planning purposes, including the preparation of our annual operating budget, as a measure of performance and the effectiveness of our business strategies, and in communications with our board of directors concerning our performance. Adjusted EBITDA may also be used as a metric for determining payment of cash incentive compensation. Adjusted EBITDA provides a measure of consistency and comparability with our past performance that many investors find useful, facilitates period-to-period comparisons of operations, and also facilitates comparisons with other peer companies, many of which use similar non-GAAP financial measures to supplement their GAAP results. Although Adjusted EBITDA is frequently used by investors and securities analysts in their evaluations of companies, Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of our results of operations as reported under GAAP. These limitations include: Stock-based compensation is a non-cash charge and is and will remain an element of our long-term incentive compensation package, although we exclude it as an expense when evaluating our ongoing operating performance for a particular period. Depreciation and amortization are non-cash charges, and the assets being depreciated or amortized will often have to be replaced in the future, but Adjusted EBITDA does not reflect any cash requirements for these replacements. Impairment charges are non-cash charges related to goodwill, intangible assets and/or long-lived assets. Adjusted EBITDA does not reflect non-cash charges related to acquisition and related items, such as amortization of acquired intangible assets and changes in the fair value of contingent consideration. Adjusted EBITDA does not reflect cash and non-cash charges and changes in, or cash requirements for, acquisition and related items, such as certain transaction expenses and expenses associated with earn-out amounts. Adjusted EBITDA does not reflect changes in our working capital needs, capital expenditures, or contractual commitments. Adjusted EBITDA does not reflect cash requirements for income taxes and the cash impact of other income or expense. Other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure. Our Adjusted EBITDA is influenced by fluctuation in our revenue and the timing and amounts of our investments in our operations. Adjusted EBITDA should not be considered as an alternative to net income (loss), operating loss, or any other measure of financial performance calculated and presented in accordance with GAAP. We define non-GAAP earnings per share as non-GAAP net income (loss) divided by non-GAAP weighted-average shares outstanding. Non-GAAP net income (loss) is equal to net income (loss) excluding stock-based compensation, impairment charges, cash and non-cash based acquisition and related expenses, including amortization of acquired intangible assets, transaction expenses, expenses associated with earn-out amounts, and foreign currency gains and losses. In periods in which non-GAAP net income (loss) is positive, non-GAAP weighted-average shares outstanding used to calculate non-GAAP earnings per share includes the impact of potentially dilutive shares. Potentially dilutive shares consist of stock options, restricted stock awards, restricted stock units, potential shares issued under the Employee Stock Purchase Plan, each computed using the treasury stock method, shares held in escrow, and potential shares issued as part of contingent consideration as a result of business combinations. We believe non-GAAP earnings per share is useful to investors in evaluating our ongoing operational performance and our trends on a per share basis, and also facilitates comparison of our financial results on a per share basis with other companies, many of which present a similar non-GAAP measure. However, a potential limitation of our use of non-GAAP earnings per share is that other companies may define non-GAAP earnings per share differently, which may make comparison difficult. This measure may also exclude expenses that may have a material impact on our reported financial results. Non-GAAP earnings per share is a performance measure and should not be used as a measure of liquidity. Because of these limitations, we also consider the comparable GAAP measure of net income (loss).
