B. Riley and Eos Complete Business Combination

Although Mallard stockholders on April 25 approved a deadline extension that would have given the SPAC room to operate until July 29, management in a regulatory filing said redemptions in connection with that vote wiped out $86.3 million of the SPAC's $110 million in trust.

The business combination values AdTheorent at a $775 million enterprise value and at a pro forma market capitalization of approximately $1 billion.
