These risks include, but are not limited to: our ability to continue to grow and to manage our growth effectively; our ability to develop innovative new technologies and remain a market leader; our ability to attract and retain buyers and sellers and increase our business with them; our vulnerability to loss of, or reduction in spending by, buyers; our reliance on large sources of advertising demand and aggregators of advertising inventory; our ability to maintain and grow a supply of advertising inventory from sellers and to fill the increased inventory; the effect on the advertising market and our business from difficult economic conditions or uncertainty; the freedom of buyers and sellers to direct their spending and inventory to competing sources of inventory and demand; our ability to use our solution to purchase and sell higher value advertising and to expand the use of our solution by buyers and sellers utilizing evolving digital media platforms; our ability to introduce new offerings and bring them to market in a timely manner, and otherwise adapt in response to client demands and industry trends, including shifts in digital advertising growth from desktop to mobile channels and from display to video formats and the introduction and market acceptance of Demand Manager; the increased prevalence of header bidding and its effect on our competitive position; uncertainty of our estimates and expectations associated with new offerings, including header bidding, private marketplace, mobile, video, Demand Manager, and traffic shaping; lower fees and take rate and the need to grow through advertising spend increases rather than fee increases; our ability to compensate for a reduced take rate by increasing the volume and/or value of transactions on our platform and increasing our fill rate; our vulnerability to the depletion of our cash resources as we incur additional investments in technology required to support the increased volume of transactions on our exchange and development of new offerings; our ability to support our growth objectives with reduced resources from our cost reduction initiatives; our ability to raise additional capital if needed and/or renew our working capital line of credit; our limited operating history and history of losses; our ability to continue to expand into new geographic markets; our ability to adapt effectively to shifts in digital advertising; increased prevalence of ad-blocking or cookie-blocking technologies; the slowing growth rate of desktop display advertising; the growing percentage of online and mobile advertising spending captured by owned and operated sites (such as Facebook, Google and Amazon); the effects, including loss of market share, of increased competition in our market and increasing concentration of advertising spending, including mobile spending, in a small number of very large competitors; the effects of consolidation in the ad tech industry; acts of competitors and other third parties that can adversely affect our business; our ability to differentiate our offerings and compete effectively in a market trending increasingly toward commodification, transparency, and disintermediation; requests for discounts, fee concessions or revisions, rebates, refunds, favorable payment terms and greater levels of pricing transparency and specificity; potential adverse effects of malicious activity such as fraudulent inventory and malware; the effects of seasonal trends on our results of operations; costs associated with defending intellectual property infringement and other claims; our ability to attract and retain qualified employees and key personnel; our ability to identify future acquisitions of or investments in complementary companies or technologies and our ability to consummate the acquisitions and integrate such companies or technologies; and our ability to comply with, and the effect on our business of, evolving legal standards and regulations, particularly concerning data protection and consumer privacy and evolving labor standards. We discuss many of these risks and additional factors that could cause actual results to differ materially from those anticipated by our forward-looking statements under the headings "Risk Factors," and "Management's Discussion and Analysis of Financial Condition and Results of Operations," and elsewhere in filings we have made and will make from time to time with the Securities and Exchange Commission, or SEC, including our Annual Report on Form 10-K for the year ended December 31, 2018 and subsequent Quarterly Reports on Form 10-Q. 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. 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: In addition to our GAAP results, we review certain non-GAAP financial measures to help us evaluate our business, measure our performance, identify trends affecting our business, establish budgets, measure the effectiveness of investments in our technology and development and sales and marketing, and assess our operational efficiencies. These non-GAAP measures include Adjusted EBITDA and Non-GAAP Income (Loss) and Non-GAAP Earnings (Loss) per share which are discussed below. 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 net loss to Adjusted EBITDA," "Reconciliation of net loss to non-GAAP loss" and "Reconciliation of GAAP loss per share to non-GAAP loss per share" included as part of this press release. 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 Income (Loss) and Non-GAAP Earnings (Loss) per Share: We define non-GAAP earnings (loss) per share as non-GAAP income (loss) divided by non-GAAP weighted-average shares outstanding. Non-GAAP 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 we have non-GAAP income, 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 (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). THE RUBICON PROJECT, INC.
