AdTheorent Holding Company, Inc. Reports Fourth Quarter and Full-Year 2022 Results and Provides First Quarter and Full-Year 2023 Guidance

Reports double-digit growth in Connected Television (CTV) revenue and Active Customers; Disruptive product launches position AdTheorent for future growth

New York, NY — March 2, 2023 — AdTheorent Holding Company, Inc. (Nasdaq: ADTH) (“AdTheorent” or “the Company”), a programmatic digital advertising leader using advanced machine learning technology and privacy-forward solutions to deliver real-world value for advertisers and marketers, today announced fourth quarter and full-year 2022 financial results.

“We accomplished many great things in our first year as a public company, such as expanding our technological advantage over competing CTV products, growing CTV revenue by 54%, growing our Active Customer base by 12%, revolutionizing the concept of what a targetable programmatic ‘Audience’ can be with the launch of our Platform’s Audience Builder and our highly customized Health Audience Builder, and launching our Direct Access business -- which is the only self-service demand side platform that offers a privacy-forward alternative to the dated, user-profile focused methods used by competitors,” said Jim Lawson, AdTheorent’s Chief Executive Officer.

“AdTheorent's advanced machine learning technology and rapidly expanding privacy-forward solutions have helped the Company stand out in a crowded market, and we are committed to continued innovation and profitable growth in 2023,” Lawson continued.

“For the fourth quarter and full year of 2022, we generated revenue, adjusted gross profit, and adjusted EBITDA above the high end of our outlook ranges. We increased cash flow growth in 2022 versus 2021 due to better operating cash flow performance and lower one-time costs related to the business combination,” stated Patrick Elliott, Chief Financial Officer. “Looking ahead, we expect growth in revenue, despite a challenging macroeconomic environment, and we remain focused on investment, profitability and cash flow.”

Fourth Quarter 2022 Financial Highlights:

Full-Year 2022 Financial Highlights:

Business and Operating Highlights:

*We prepare our consolidated financial statements in accordance with the U.S. generally accepted accounting principles (“GAAP”). Adjusted Gross Profit and Adjusted EBITDA are non-GAAP financial measures. See the supplementary schedules in this press release for a discussion of how we define and calculate these measures and a reconciliation thereof to the most directly comparable GAAP measures.

2023 Financial Outlook

The Company's growth may continue to be impacted in 2023 by macroeconomic factors beyond its control, such as inflationary pressures and recessionary fears. Based on the current business environment, recent performance and the current trends in the marketplace and subject to the risks and uncertainties inherent in forward-looking statements, the Company's outlook for the first quarter and full-year 2023 includes the following:

First quarter of 2023:

Full-year ending December 31, 2023:

Although the Company provides guidance for Adjusted EBITDA, it is not able to provide guidance for net income, the most directly comparable GAAP measure. Certain elements of the composition of net income, including equity-based compensation, are not predictable, making it impractical for us to provide guidance on net income or to reconcile our Adjusted EBITDA guidance to net income without unreasonable efforts. Similarly, although the Company provides guidance for Adjusted Gross Profit, it is not able to provide guidance for Gross Profit, the most directly comparable GAAP measure. Certain elements of the composition of Gross Profit, including equity-based compensation, are not predictable, making it impractical for the Company to provide guidance on Gross Profit or to reconcile our Adjusted Gross Profit guidance to Gross Profit without unreasonable efforts. For the same reasons, the Company is unable to address the probable significance of the unavailable information regarding net income and Gross Profit, which could be material to future results.

Non-GAAP Financial Measures

We use financial measures that are not calculated in accordance with U.S. GAAP, including Adjusted EBITDA and Adjusted Gross Profit. Our management believes that this information can assist investors in evaluating our operational trends, financial performance, and cash generating capacity and make strategic decisions. Management believes these non-GAAP measures allow investors to evaluate our financial performance using some of the same measures as management.

Because of the limitations associated with these non-GAAP financial measures, “Adjusted Gross Profit,” “EBITDA,” “Adjusted EBITDA,” “Adjusted Gross Profit as a percentage of Revenue” and “Adjusted EBITDA as a percent of Adjusted Gross Profit” should not be considered in isolation or as a substitute for performance measures calculated in accordance with GAAP. We compensate for these limitations by relying primarily on our GAAP results and using non-GAAP measures on a supplemental basis. You should review the reconciliation of the non-GAAP financial measures below and not rely on any single financial measure to evaluate our business.

The tables below show our non-GAAP financial metrics reconciled to the comparable GAAP financial metrics included in this release.

Adjusted Gross Profit

Adjusted Gross Profit is a non-GAAP profitability measure. Adjusted Gross Profit is a non-GAAP financial measure of campaign profitability, monitored by management and the board, used to evaluate our operating performance and trends, develop short- and long-term operational plans, and make strategic decisions regarding the allocation of capital. We believe this measure provides a useful period-to-period comparison of campaign profitability and is useful information to investors and the market in understanding and evaluating our operating results in the same manner as our management and board. Gross profit is the most comparable GAAP measurement, which is calculated as revenue less platform operations costs. In calculating Adjusted Gross Profit, we add back other platform operations costs, which consist of amortization expense related to capitalized software, depreciation expense, allocated costs of personnel which set up and monitor campaign performance, and platform hosting, license, and maintenance costs, to gross profit.

The following table sets forth a reconciliation of revenue to adjusted gross profit for the periods presented:

EBITDA and Adjusted EBITDA

EBITDA is a non-GAAP financial measure defined by us as net income (loss), before interest expense, net, depreciation, amortization and income tax expense. Adjusted EBITDA is defined as EBITDA before stock compensation expense, transaction costs, management fees, non-core operations and other non-recurring items. Net income (loss) is the most comparable GAAP measurement.

Collectively these non-GAAP financial measures are key profitability measures used by our management and board 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. We believe that these measures can provide useful period-to-period comparisons of campaign profitability. Accordingly, we believe that these measures provide useful

information to investors and the market in understanding and evaluating our operating results in the same manner as our management and board.

The following table sets forth a reconciliation of net income to Adjusted EBITDA for the periods presented:
