Outbrain Announces Fourth Quarter and Full Year 2021 Results

Record revenues of $290 million in Q4; FY 2021 growth of 32% to over $1 billion in revenues
Ex-TAC gross profit and Adjusted EBITDA exceed high end of guidance

NEW YORK, March 01, 2022 (GLOBE NEWSWIRE) -- Outbrain Inc. (Nasdaq: OB), a leading recommendation platform for the open web, announced today financial results for the quarter and full year ended December 31, 2021.

“We are pleased to report a strong finish to a pivotal year for Outbrain,” said David Kostman, Outbrain's Co-CEO. “We completed our IPO, grew our team by nearly 200 people, surpassed $1 billion in revenues with more advertisers than ever using our platform, and finished the year with the acquisition of video intelligence AG. I want to take this opportunity to thank our more than 1,000 employees that are making this happen every day. With a world class team, strong momentum in media partner wins and a strong balance sheet, I believe we are very well positioned to continue to execute across all of our main growth drivers.”

“As pioneers of our space, I'm most proud of our continued thought leadership and innovation on products and technologies that drive value for our media and advertising partners. I believe that leveraging our unique position with media owners to provide them with additional solutions to promote their business objectives and solidifying our differentiated product leadership with Smartlogic for media owners and Conversion Bid Strategy (CBS) and Engagement Bid Strategy (EBS) for advertisers will continue to fuel our growth,” added Yaron Galai, Outbrain’s Co-Founder and Co-CEO. “I’m excited about the deep product pipeline that will be positioning us to expand to broader services and value propositions for our partners in the future.”

Fourth Quarter 2021 Highlights:

Full Year 2021 Highlights:

Share Repurchase Authorization
On February 28, 2022, the Company’s Board of Directors authorized a new $30 million share repurchase program which is expected to be funded through cash generated from operations. The Company believes it is an attractive way to enhance shareholder value under current market conditions without compromising investments in growth opportunities.

The timing and actual number of shares repurchased under the program will depend on a variety of factors, including price, general business and market conditions, and other investment opportunities. Shares may be repurchased through privately negotiated transactions, or open market purchases, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Exchange Act. The share repurchase program does not obligate Outbrain to acquire any particular amount of common stock, and the program and repurchases under the program may be commenced, suspended or terminated, as applicable, at any time by the Company at its discretion without prior notice.

2022 Full Year and First Quarter Guidance
The following forward-looking statements reflect our expectations. For the full year ended December 31, 2022, we expect:

For the first quarter ending March 31, 2022, we expect:

The above measures are forward-looking non-GAAP financial measures for which a reconciliation to the most directly comparable GAAP financial measure is not available without unreasonable efforts. See “Non-GAAP Financial Measures” below. In addition, our guidance is subject to risks and uncertainties, as outlined below in this release.

___________________
1 We calculate media partner net revenue retention at the end of each quarter by starting with revenue generated on media partners’ properties in the same period in the prior year, “Prior Period Retention Revenue.” We then calculate the revenue generated on these same media partners’ properties in the current period, “Current Period Retention Revenue.” Current Period Retention Revenue reflects any expansions within the media partner relationships, such as any additional placements or properties on which we extend our recommendations, as well as contraction or attrition. Our media partner net revenue retention in a quarter equals the Current Period Retention Revenue divided by the Prior Period Retention Revenue. These amounts exclude certain revenue adjustments and revenue recognized on a net basis. New media partners are defined as those relationships in which revenue was not generated in the prior year period, except for limited instances where residual revenue was generated on a media partner’s properties. In such instances, the residual revenue would be excluded from net revenue retention above.

Interested investors and other parties may also listen to a simultaneous webcast of the conference call by logging onto the Investors Relations section of the Company’s website at https://investors.outbrain.com. The online replay will be available for a limited time shortly following the call.

Non-GAAP Financial Measures

In addition to GAAP performance measures, we use the following supplemental non-GAAP financial measures to evaluate our business, measure our performance, identify trends and allocate our resources: Ex-TAC gross profit, Adjusted EBITDA, free cash flow, adjusted net income and adjusted diluted EPS. These non-GAAP financial measures are defined and reconciled to the corresponding GAAP measures. These non-GAAP financial measures are subject to significant limitations, including those we identify below. In addition, other companies in our industry may define these measures differently, which may reduce their usefulness as comparative measures. As a result, this information, should be considered as supplemental in nature and is not meant as a substitute for revenue, gross profit, net income, diluted EPS or cash flows from operating activities presented in accordance with U.S. GAAP.

The Company is also providing first quarter and full year 2022 guidance on a non-GAAP basis. These forward-looking non-GAAP financial measures are calculated based on internal forecasts that omit certain amounts that would be included in GAAP financial measures. The Company has not provided quantitative reconciliations of these forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures because it is unable, without unreasonable effort, to predict with reasonable certainty the occurrence or amount of all excluded items that may arise during the forward-looking period, which can be dependent on future events that may not be reliably predicted. Such excluded items could be material to the reported results individually or in the aggregate.

Ex-TAC Gross Profit

Ex-TAC gross profit is a non-GAAP financial measure. Gross profit is the most comparable GAAP measure. In calculating Ex-TAC gross profit, we add back other cost of revenue to gross profit. Ex-TAC gross profit may fluctuate in the future due to various factors, including, but not limited to, seasonality and changes in the number of media partners and advertisers, advertiser demand or user engagements.

We present Ex-TAC gross profit, Adjusted EBITDA, and Adjusted EBITDA as a percentage of Ex-TAC gross profit because they are key profitability measures used by our management and board of directors to understand and evaluate our operating performance and trends, develop short-and long-term operational plans and make strategic decisions regarding the allocation of capital. Accordingly, we believe that these measures provide information to investors and the market in understanding and evaluating our operating results in the same manner as our management and board of directors. There are limitations on the use of Ex-TAC gross profit in that traffic acquisition cost is a significant component of our total cost of revenue but not the only component and, by definition, Ex-TAC gross profit presented for any period will be higher than gross profit for that period. A potential limitation of this non-GAAP financial measure is that other companies, including companies in our industry, which have a similar business, may define ex-TAC gross profit differently, which may make comparisons difficult. As a result, this information, should be considered as supplemental in nature and is not meant as a substitute for revenue or gross profit presented in accordance with U.S. GAAP.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) before charges related to exchange of senior notes upon IPO; interest expense; interest income and other income (expense), net; provision for income taxes; depreciation and amortization; stock-based compensation, and other income or expenses that we do not consider indicative of our core operating performance, including but not limited to, merger and acquisition costs, certain IPO related costs, regulatory matter costs and a prior year tax contingency. We present Adjusted EBITDA as a supplemental performance measure because we believe it facilitates operating performance comparisons from period to period.

We believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and board of directors. However, our calculation of Adjusted EBITDA is not necessarily comparable to non-GAAP information of other companies. Adjusted EBITDA should be considered as a supplemental measure and should not be considered in isolation or as a substitute for any measures of our financial performance that are calculated and reported in accordance with GAAP.

Adjusted Net Income and Adjusted Diluted EPS

Adjusted net income (loss) is a non-GAAP financial measure, which is defined as net income (loss) excluding items that we do not consider indicative of our core operating performance, including but not limited to, charges related to the exchange of senior notes upon IPO, the cumulative incremental stock-based compensation expense impact for awards with an IPO performance condition, merger and acquisition costs, certain IPO related costs, deferred tax asset valuation allowance release, regulatory matter costs and a prior year tax contingency. Adjusted net income (loss), as defined above, is also presented on a per diluted share basis. We present adjusted net income (loss) and adjusted diluted EPS as supplemental performance measures because we believe they facilitate performance comparisons from period to period. However, adjusted net income (loss) or adjusted diluted EPS should not be considered in isolation or as a substitute for net income (loss) or diluted earnings per share reported in accordance with GAAP.

Free Cash Flow

Free cash flow is defined as cash flow from operating activities less capital expenditures and capitalized software development costs. Free cash flow is a supplementary measure used by our management and board of directors to evaluate our ability to generate cash and we believe it allows for a more complete analysis of our available cash flows. Free cash flow should be considered as a supplemental measure and should not be considered in isolation or as a substitute for any measures of our financial performance that are calculated and reported in accordance with GAAP.

Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the federal securities laws, which statements involve substantial risks and uncertainties. Forward-looking statements generally relate to possible or assumed future results of our business, financial condition, results of operations, liquidity, plans and objectives. You can generally identify forward-looking statements because they contain words such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “guidance,” “outlook,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential” or “continue” or the negative of these terms or other similar expressions that concern our expectations, strategy, plans or intentions. We have based these forward-looking statements largely on our current expectations and projections regarding future events and trends that we believe may affect our business, financial condition and results of operations. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors, including but not limited to: overall advertising demand and traffic generated by our media partners; factors that affect advertising spending, such as economic downturns and unexpected events; any failure of our recommendation engine to accurately predict user engagement, any deterioration in the quality of our recommendations or failure to present interesting content to users or other factors which may cause us to experience a decline in user engagement or loss of media partners; limits on our ability to collect, use and disclose data to deliver advertisements; the effects of the ongoing and evolving COVID-19 pandemic, including the resulting global economic uncertainty, and measures taken in response to the pandemic; our ability to continue to innovate, and adoption by our advertisers and media partners of our expanding solutions; our ability to meet demands on our infrastructure and resources due to future growth or otherwise; our ability to extend our reach into evolving digital media platforms; our ability to maintain and scale our technology platform; our ability to grow our business and manage growth effectively; the success of our sales and marketing investments, which may require significant investments and may involve long sales cycles; the risk that our research and development efforts may not meet the demands of a rapidly evolving technology market; the loss of one or more of our large media partners, and our ability to expand our advertiser and media partner relationships; our ability to compete effectively against current and future competitors; failures or loss of the hardware, software and infrastructure on which we rely, or security breaches; our ability to maintain our profitability despite quarterly fluctuations in our results, whether due to seasonality, large cyclical events, or other causes; political and regulatory risks in the various markets in which we operate; the challenges of compliance with differing and changing regulatory requirements; and the risks described in the section entitled “Risk Factors” and elsewhere in the Quarterly Report on Form 10-Q filed for the quarter ended September 30, 2021 and in subsequent reports filed with the SEC. Accordingly, you should not rely upon forward-looking statements as predictions of future events. We cannot assure you that the results, events and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events or circumstances could differ materially from those projected in the forward-looking statements. We undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. We do not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

(1)  Reflects the one-time cumulative incremental stock-based compensation expense impact for awards with an IPO performance condition.
(2)  Primarily includes costs related to our terminated merger with Taboola.com Ltd. (“Taboola”), costs related to our acquisition of video intelligence AG (“vi”), and costs related to our initial public offering and SOX implementation.
(3)  Reflects a reversal of a tax contingency recorded within operating expenses in 2019 and a corresponding charge to income tax expense in 2020, net of foreign exchange impact.
(4)  Reflects a significant one-time tax benefit due to a release of the valuation allowance on certain U.S. deferred tax assets.
(5) The Company uses the if-converted method to compute diluted earnings per share with respect to its convertible senior notes. Reported and adjusted weighted average shares used to compute reported and adjusted diluted earnings per share for the three months ended December 31, 2021 include the dilutive effect of convertible senior notes of 9,440,000 shares. Reported weighted average shares used to compute reported diluted earnings per share for the year ended December 31, 2021 do not include the effect of convertible senior notes of 9,440,00 because they were antidilutive. Adjusted diluted earnings per share for the year ended December 31, 2021 includes the dilutive effect of convertible senior notes from the date of issuance.
