Key Operational and Non-GAAP Financial Measures

Rubicon Project’s management evaluates and makes operating decisions using various operational and financial measures.

Operational Measures

Managed revenue is an operational measure that represents the advertising spending transacted on our platform, and would represent our revenue if we were to record our revenue on a gross basis instead of a net basis. Managed revenue does not represent revenue reported in accordance with generally accepted accounting principles in the United States (“GAAP”). We review managed revenue for internal management purposes to assess market share and scale. Many companies in our industry record revenue on a gross basis, so tracking our managed revenue allows us to compare our results to the results of those companies. Our managed revenue is influenced by the volume and characteristics of paid impressions and average CPM.

Take rate is an operational measure that represents our share of managed revenue. We review take rate for internal management purposes to assess the development of our marketplace with buyers and sellers. Our 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, product mix, the implementation of new products, platforms and solution features, auction dynamics, and the overall development of the digital advertising ecosystem.

Paid impressions is an operational measure. We define a paid impression as an impression sold to a buyer and into which an advertisement is served for display to a user on a website or mobile application, which is transacted via our platform through either direct, or indirect relationships between buyers and sellers and us, or between buyers and sellers directly. We use paid impressions as one measure to assess the performance of our platform, including the effectiveness and efficiency at which buyers and sellers are trading via our platform and using our solution, and to assist us in tracking our revenue-generating performance and operational efficiencies. The number of paid impressions may fluctuate based on various factors, including the number and spend of buyers using our solution, the number of sellers, their allocation of advertising inventory using our solution, our traffic quality control initiatives, and the seasonality in our business. Because of the volatility of this metric, we believe that paid impressions are useful to review on an annual basis.

Pricing is generally expressed as average cost per thousand impressions, or average CPM. Average CPM is an operational measure that represents the average price at which paid impressions are sold. We review average CPM for internal management purposes to assess buyer spend, liquidity in the marketplace, inventory quality, and integrity of our algorithms. Average CPM may be influenced by our inventory placements and demand for such inventory facilitated by our relationships with both buyers and sellers, as well as by a variety of other factors, including the precision of matching an advertisement to an audience, changes in our algorithms, seasonality, quality of inventory provided by sellers, penetration of various channels and advertising units, and changes in buyer spend levels. We expect average CPM to increase with the continued adoption of our solution by premium buyers and sellers, resulting in a higher quantity of premium advertising inventory available to advertisers. Because of the volatility of this metric, we believe that average CPM is useful to review on an annual basis. We compute average CPM by dividing managed revenue by total paid impressions and multiplying by 1,000.

Financial Measures

This press release includes information relating to Adjusted EBITDA, Adjusted EBITDA margin, and non-GAAP earnings (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 operating performance and trends, to prepare and approve our annual budget, and to develop short- and long-term operational plans. Management believes that these non-GAAP financial measures provide useful information about our core operating results and thus are appropriate to enhance the overall understanding of our past financial 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. Adjusted EBITDA, Adjusted EBITDA margin, and non-GAAP earnings (loss) per share eliminate the impact of items that we do not consider indicative of our core operating performance and operating performance on a per share basis. You are encouraged to evaluate these adjustments, and review the reconciliation of these non-GAAP measures to their most comparable GAAP financial 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 income (loss) to Adjusted EBITDA” and “Calculation of net income (loss) attributable to common stockholders to non-GAAP earnings (loss) per share” included as part of this press release.

We define Adjusted EBITDA as net income (loss) adjusted for stock-based compensation expense, depreciation and amortization, interest income or expense, change in fair value of pre-IPO convertible preferred stock warrant liabilities, and other income or expense, which mainly consists of foreign exchange gains and losses, certain other non-recurring income, or expenses such as acquisition and related costs, and provision for income taxes. We believe Adjusted EBITDA is useful to investors in evaluating our operating performance for the following reasons:

•

Adjusted EBITDA is widely used by investors and securities analysts to measure a company’s operating performance without regard to items such as stock-based compensation expense, depreciation and amortization, interest income or expense, change in fair value of preferred stock warrant liabilities, foreign exchange gains and losses, certain other non-recurring income or expense such as acquisition and related costs, and provision for income taxes that 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 operating performance and the effectiveness of our business strategies, and in communications with our board of directors concerning our financial performance;


•	Adjusted EBITDA may sometimes be considered by the compensation committee of our board of directors in connection with the determination of compensation for our executive officers; and


•	Adjusted EBITDA provides consistency and comparability with our past financial performance, facilitates period-to-period comparisons of operations, and 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 you should not consider it 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; Adjusted EBITDA does not reflect any cash requirements for these replacements;


•	Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs, capital expenditures or contractual commitments, and therefore may not reflect periodic increases in capital expenditures;


•	Adjusted EBITDA does not reflect cash requirements for income taxes and the cash impact of other income or expense; and


•	other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Adjusted EBITDA margin is a financial measure and is calculated as Adjusted EBITDA divided by revenue.

Because of these limitations, we also consider other financial measures, including net income (loss).

Non-GAAP earnings (loss) per share is calculated by dividing non-GAAP net income (loss) by non-GAAP weighted-average shares outstanding. Non-GAAP net income (loss) is equal to net income (loss) attributable to common stockholders excluding the change in fair value of pre-IPO convertible preferred stock warrant liabilities, cumulative preferred stock dividends, stock-based compensation, acquisition and related items expense, including amortization of acquired intangible assets, and foreign currency gains and losses. The non-GAAP weighted-average shares outstanding used to calculate non-GAAP earnings (loss) per share assume the net exercise of a preferred stock warrant and the conversion of each share of convertible preferred stock to one half share of common stock in connection with our initial public offering as if they had occurred at the beginning of each respective period presented, whereas, weighted-average shares outstanding used to calculate GAAP earnings (loss) per share reflect the net exercise and conversion as of April 7, the date our IPO closed. In periods in which non-GAAP net income (loss) is profitable, non-GAAP weighted-average shares outstanding used to calculate non-GAAP earnings per share include 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. The weighted-average shares used to compute net income (loss) per share, non-GAAP weighted-average shares outstanding used to compute non-GAAP earnings (loss) per share, and non-GAAP weighted-average shares outstanding used in our guidance for the full year non-GAAP earnings (loss) per share include the 6.4 million shares issued in our initial public offering from the date our IPO closed. 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 by taking into consideration all preferred stock ownership on an as-converted 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. Because of these limitations, we also consider the comparable GAAP financial measure of net income (loss) attributable to common stockholders.
