We are also seeing early benefits from our streamer.ai acquisition. The additional AI tools have supported new business wins, particularly among SMB advertisers, further enhancing our competitive positioning. DV+ continues to perform well, growing in line with expectations, driven by exclusive partner expansion. We were encouraged by the Google remedies hearings and look forward to the positive impact on our DV+ business once remedies are implemented.” said Michael G. Barrett, CEO of Magnite.

This press release and management’s prepared remarks during the conference call referred to above include, and management’s answers to questions during the conference call may include, forward-looking statements, including statements based upon or relating to our expectations, assumptions, estimates, and projections. In some cases, you can identify forward-looking statements by terms such as “may,” “might,” “will,” “objective,” “intend,” “should,” “could,” “can,” “would,” “expect,” “believe,” “design,” “anticipate,” “estimate,” “predict,” “potential,” “plan” or the negative of these terms, and similar expressions. Forward-looking statements may include, but are not limited to, statements concerning the Company’s guidance or expectations with respect to future financial performance; acquisitions by the Company, or the anticipated benefits thereof; macroeconomic conditions or concerns related thereto; the growth of ad-supported programmatic connected television (“CTV”); our ability to use and collect data to provide our offerings; the scope and duration of client relationships; the fees we may charge in the future; key strategic objectives; anticipated benefits of new offerings; business mix; sales growth; benefits from supply path optimization; our ability to adapt to advancements in artificial intelligence; the development of identity solutions; client utilization of our offerings; the impact of requests for discounts, rebates, or other fee concessions; our competitive differentiation; our market share and leadership position in the industry; market conditions, trends, and opportunities; the effects of regulatory developments or antitrust rulings on competitive dynamics in our industry; our litigation against Google LLC, or the anticipated benefits thereof; certain statements regarding future operational performance measures; and other statements that are not historical facts. These statements are not guarantees of future performance; they reflect our current views with respect to future events and are based on assumptions and estimates and subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from expectations or results projected or implied by forward-looking statements.

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 this press release and in other 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, 2024, our Quarterly Report on Form 10-Q for the period ended March 31, 2025, and subsequent filings. These forward-looking statements represent our estimates and assumptions only as of the date of the report in which they are included. 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 and Operational Measures:

In addition to our GAAP results, we review certain non-GAAP financial measures to help us evaluate our business on a consistent basis, 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 financial measures include Contribution ex-TAC, Adjusted EBITDA, Non-GAAP Income (Loss), and Non-GAAP Earnings (Loss) per share, each of which is 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 Revenue to Gross Profit to Contribution ex-TAC,” “Reconciliation of net income (loss) to Adjusted EBITDA,” “Reconciliation of net income (loss) to non-GAAP income,” and “Reconciliation of GAAP earnings (loss) per share to non-GAAP earnings per share” included as part of this press release.

We do not provide a reconciliation of our non-GAAP financial expectations for Contribution ex-TAC and Adjusted EBITDA, or a forecast of the most comparable GAAP measures, because the amount and timing of many future charges that impact these measures (such as amortization of future acquired intangible assets, acquisition-related charges, foreign exchange (gain) loss, net, stock-based compensation, impairment charges, provision or benefit for income taxes, and our future revenue mix), which could be material, are variable, uncertain, or out of our control and therefore cannot be reasonably predicted without unreasonable effort, if at all. In addition, we believe such reconciliations or forecasts could imply a degree of precision that might be confusing or misleading to investors.

Contribution ex-TAC:

Contribution ex-TAC is calculated as gross profit plus cost of revenue, excluding traffic acquisition cost (“TAC”). Traffic acquisition cost, a component of cost of revenue, represents what we must pay sellers for the sale of advertising inventory through our platform for revenue reported on a gross basis. Contribution ex-TAC is a non-GAAP financial measure that is most comparable to gross profit. We believe Contribution ex-TAC is a useful measure in facilitating a consistent comparison against our core business without considering the impact of traffic acquisition costs related to revenue reported on a gross basis.

Adjusted EBITDA:

We define Adjusted EBITDA as net income (loss) adjusted to exclude stock-based compensation expense, depreciation and amortization, including amortization of acquired intangible assets, impairment charges, interest income or expense, provision (benefit) for income taxes, and certain 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, gains or losses on extinguishment of debt, other debt refinancing expenses, certain litigation expenses, and non-operational real estate and other expenses (income), net. 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 is also 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 certain cash and non-cash charges related to acquisition and related items, such as amortization of acquired intangible assets, merger, acquisition, or restructuring related severance costs, certain transaction expenses, and changes in the fair value of contingent consideration.
Adjusted EBITDA does not reflect cash and non-cash charges related to interest income and interest expense and certain financing transactions such as gains or losses on extinguishment of debt or other debt refinancing expenses.
Adjusted EBITDA does not reflect cash requirements for income taxes and the cash impact of other income or expense.
Adjusted EBITDA does not reflect litigation expenses for specific proceedings.
Adjusted EBITDA does not reflect certain non-operational real estate and other (income) and expense, net.
Adjusted EBITDA does not reflect changes in our working capital needs, capital expenditures, or contractual commitments.
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, cost of revenue, and the timing and amounts of the cost of our operations. Adjusted EBITDA should not be considered as an alternative to net income (loss), income (loss) from operations, 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, cash and non-cash based merger, acquisition, and restructuring costs, which consist primarily of professional service fees associated with merger and acquisition activities, cash-based employee termination costs, and other restructuring activities, including facility closures, relocation costs, contract termination costs, and impairment costs of abandoned technology associated with restructuring activities, amortization of acquired intangible assets, gains or losses on extinguishment of debt, certain litigation expense, non-operational real estate and other expenses or income, foreign currency gains and losses, interest expense associated with Convertible Senior Notes, other debt refinance expenses, and the tax impact of these items. 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 units, performance stock units, and potential shares issued under the Employee Stock Purchase Plan, each computed using the treasury stock method, and the impact of shares that would be issuable assuming conversion of all of the Convertible Senior Notes, calculated under the if-converted method. 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).
