Rubicon Project Reports Second Quarter 2018 Results PDF Version Advertising Spend Growth Accelerates LOS ANGELES, Aug. 01, 2018 (GLOBE NEWSWIRE) -- Rubicon Project(NYSE:RUBI), the global exchange for advertising, today reported its results of operations for the second quarter of 2018. Recent Highlights Revenue was $28.6 million for Q2 2018, up 15% sequentially from Q1 2018 Year over year ad spend(3) growth of 10% in Q1, 16% in Q2, and expected to be greater than 20% in Q3 2018 Take rate(3) increased to 12.1% in Q2 2018 and is expected to be at or slightly above this level in Q3 2018 Q3 2018 revenue expected to be flat to slightly up sequentially First half of 2018 amounts paid to sellers highest in company history Crossed milestone of 1,000 header bidding connections in Q2 2018; header bidding transactions now represent over 77% of revenue Programmatic video and audio drove significant year-over-year growth in ad spend Mobile ad spend in Q2 2018 grew 40% year over year and represented slightly over 50% of total ad spend Net loss(2) was $18.0 million, or loss per share(2) of $0.36, compared to net loss of $11.6 million, or loss per share of $0.24 for the second quarter of 2017. Adjusted EBITDA(1) was a negative $5.5 million, compared to adjusted EBITDA of $3.0 million for the second quarter of 2017. Non-GAAP loss per share(1) was $0.27, compared to $0.10 non-GAAP loss per share for the second quarter of 2017. “We are pleased to demonstrate accelerating ad spend growth this quarter, which we believe is directly correlated to the strategic actions and investments made in our platform over the past year. Video, audio and mobile continue to provide strong growth for us, and differentiate us from many of our peers,” said Michael G. Barrett, President and CEO of Rubicon Project. “Industry consolidation is gaining momentum and we continue to believe this will provide a positive market dynamic for us to gain share as a leading independent exchange. Our increasing ad spend growth rate gives us greater confidence that we will achieve positive adjusted EBITDA in the fourth quarter of this year.” Second Quarter 2018 Results Summary (in millions, except per share amounts and percentages) Three Months Ended Six Months Ended June 30, 2018 June 30, 2017 Change Favorable/ (Unfavorable) June 30, 2018 June 30, 2017 Change Favorable/ (Unfavorable) Revenue $28.6 $42.9 (33)% $53.5 $88.9 (40)% Advertising spend(1) $237.7 $204.4 16% $448.7 $395.9 13% Non-GAAP net revenue(1) $28.6 $42.9 (33)% $53.5 $88.3 (39%) Take rate(3) 12.1% 21.0% (9 ppt) 11.9% 22.3% (10 ppt) Net loss ($18.0) ($11.6) (56)% ($45.8) ($27.4) (67%) Adjusted EBITDA(1) ($5.5) $3.0 nm ($19.7) $4.1 nm Adjusted EBITDA margin(2) (19%) 7% (26 ppt) (37%) 5% (42 ppt) Basic and diluted loss per share ($0.36) ($0.24) (50)% ($0.92) ($0.56) (64%) Non-GAAP loss per share(1) ($0.27) ($0.10) (170)% ($0.71) ($0.26) (173%) Definitions: (1) Non-GAAP net revenue, Adjusted EBITDA, non-GAAP loss per share, and advertising spend 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 revenue (or for periods in which we have revenue reported on a gross basis, 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."

These forward-looking statements represent our estimates and assumptions only as of the date 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.

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 loss, and non-GAAP loss 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 loss" and "Reconciliation of GAAP loss per share to non-GAAP loss per share" included as part of this press release. Advertising Spend: We define advertising spend as the total volume of spending between buyers and sellers transacted on our platform. Advertising spend does not represent revenue reported on a GAAP basis. Tracking our advertising spend facilitates comparison of our results to the results of companies in our industry that report 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, our ability to fill bid requests, the nature and amount of fees we charge, and other factors such as changes in the market, our execution of the business, and competition. Advertising spend may fluctuate due to seasonality. In the past, we have experienced higher advertising spend during the fourth quarter of a given year because many buyers devote a disproportionate amount of their advertising budgets to this period of the year to coincide with increased holiday purchasing. Buyers' focus on the fourth quarter generates more bidding activity on our platform, which may drive higher volumes of paid impressions, average CPM, or both. Our advertising spend grew 16% and 13% for the three and six months ended June 30, 2018, respectively, compared to the same periods in 2017. The increase in advertising spend was driven by higher ad request volumes and an increase in the CPMs generated from our auctions. The increase in CPMs was driven by increased bidding activity on our platform, the value of the inventory that we made available to buyers, including PMP, mobile and video inventory that typically carries higher pricing, and auction dynamics, including the implementation of first price auctions and Estimated Market Rate ("EMR") for our header bidding inventory. In January 2018, we made first price our default auction dynamic for header bidding transactions. Non-GAAP Net Revenue: We define non-GAAP net revenue as GAAP revenue less amounts we pay sellers, where the amounts paid are included within cost of revenue for the portion of our revenue reported on a gross basis. The portion of our revenue reported on a gross basis was attributable to intent marketing services, which no longer generated revenue after the first quarter of 2017. Historically, non-GAAP net revenue was a useful measure in assessing the performance of our business in periods for which our revenue included revenue reported on a gross basis, because it showed the operating results of our business on a consistent basis without the effect of differing revenue reporting (gross vs. net) that we applied under GAAP across different types of transactions, and facilitated comparison of our results to the results of companies that report all of their revenue on a net basis. Revenue from intent marketing services in the first quarter of 2017 created the difference between our non-GAAP net revenue and our GAAP revenue for that period. We ceased offering our intent marketing solution in the first quarter of 2017, so for subsequent periods non-GAAP net revenue is the same as GAAP revenue, as there is no longer a reconciling item between GAAP and non-GAAP net revenue. Non-GAAP net revenue is presented for comparative purposes as the first quarter of 2017 still included the intent marketing solution reconciling item. 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 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. 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 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 fluctuations 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. Non-GAAP Net Income (Loss) and Non-GAAP Earnings (Loss) per Share: We define non-GAAP earnings (loss) 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 (loss) 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 (loss) 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 (loss) per share is that other companies may define non-GAAP earnings (loss) 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 (loss) 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).
