AdTheorent Holding Company, Inc. Enters into Agreement to be Acquired by Cadent, LLC

for Approximately $324 Million Representing $3.21 Per Share

NEW YORK. April 1, 2024 (GLOBE NEWSWIRE) – AdTheorent Holding Company, Inc. (“AdTheorent” or the “Company”) (Nasdaq: ADTH), a machine learning pioneer delivering measurable value for programmatic advertisers, and Cadent, LLC (“Cadent”), a leading provider of platform-based converged TV advertising solutions and a portfolio company of Novacap, one of North America’s established private equity firms, today announced that they have entered into a definitive agreement under which a wholly owned subsidiary of Cadent will acquire the Company in an all-cash transaction. Upon closing of the transaction, AdTheorent will become a privately held company.

Under the terms of the definitive merger agreement, which has been unanimously approved by AdTheorent’s Board of Directors (the “Board”), the Company’s common stockholders will receive cash consideration of $3.21 per share. The transaction represents an equity value for the Company of approximately $324 million and represents a 17% premium to the 60-day volume weighted average stock price as of March 28, 2024 and a 27% premium to the 90-day volume weighted average stock price as of March 28, 2024. The definitive merger agreement also includes a 33-day “go shop” period that will allow the Company to affirmatively solicit alternative proposals from interested parties.

“The AdTheorent Board determined that this transaction delivers immediate, certain and significant value to the Company’s shareholders reflecting the tremendous commitment and work of our employees and stakeholders,” said Eric Tencer, AdTheorent’s Chairman of the Board. “The transaction and the upcoming “go shop” process underscores the Board’s commitment to maximizing value for shareholders.”

James Lawson, CEO of AdTheorent, said, “The transaction validates the actions and investments we have made to best position AdTheorent in our target markets since becoming a public company two years ago. The partnership with Cadent and Novacap will provide AdTheorent additional scale and resources for continued success as part of a private company.”

Transaction Details:

The transaction is expected to be completed by the third quarter of 2024 and is subject to approval by AdTheorent’s stockholders, expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as well as other customary closing conditions. Upon completion of the transaction, AdTheorent common stock will no longer be listed on the Nasdaq Stock Exchange or trade in any other public market.

Fully committed debt financing in support of the transaction is being provided by Royal Bank of Canada. The transaction is not subject to a financing condition.

The definitive merger agreement includes a 33-day “go-shop” period that will expire at 11:59 PM ET on May 4, 2024, which permits AdTheorent and its financial advisor to actively solicit and consider alternative acquisition proposals. There can be no assurance that this process will result in a superior proposal, and the Company does not intend to disclose developments with respect to the “go-shop” process unless and until it determines such disclosure is appropriate or is otherwise required.

H.I.G. Growth Partners, LLC and its affiliated investors, along with members of the AdTheorent Board and management who together own or control approximately 40% of the Company’s outstanding shares, have each entered into a voting and support agreement pursuant to which they have agreed, among other things, to vote their respective shares of AdTheorent common stock in favor of the transaction.
