2024 Full Year and First Quarter Guidance

The following forward-looking statements reflect our expectations for 2024.

For the first quarter ending March 31, 2024, we expect:

• Ex-TAC gross profit of $50.5 million to $53.5 million

• Adjusted EBITDA of $(1) million to $1 million
  

For the full year ending December 31, 2024, 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.

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, Ex-TAC margin, Adjusted EBITDA, free cash flow, adjusted net income (loss), and adjusted diluted EPS. These non-GAAP financial measures are defined and reconciled to the corresponding GAAP measures below. 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 (loss), diluted EPS, or cash flows from operating activities presented in accordance with U.S. GAAP.

Because we are a global company, the comparability of our operating results is affected by foreign exchange fluctuations. We calculate certain constant currency measures and foreign currency impacts by translating the current year’s reported amounts into comparable amounts using the prior year’s exchange rates. All constant currency financial information being presented is non-GAAP and should be used as a supplement to our reported operating results. We believe that this information is helpful to our management and investors to assess our operating performance on a comparable basis. However, these measures are not intended to replace amounts presented in accordance with GAAP and may be different from similar measures calculated by other companies.

The Company is also providing first quarter and full year 2024 guidance and forward-looking financial information regarding 2025 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, as well as 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-term 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 gain on convertible debt; 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 public company implementation related costs, regulatory matter costs, and severance costs related to our cost saving initiatives. We present Adjusted EBITDA as a supplemental performance measure because it is a key profitability measure used by our management and board of directors to understand and evaluate our operating performance and trends, develop short-term and long-term operational plans and make strategic decisions regarding the allocation of capital, and 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 U.S. GAAP.

Adjusted Net Income (Loss) 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 gain on convertible debt, merger and acquisition costs, certain public company implementation related costs, regulatory matter costs, and severance costs related to our cost saving initiatives. 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 U.S. GAAP.

Free Cash Flow

Free cash flow is defined as cash flow provided by (used in) 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 U.S. GAAP.
