Theodore L. Koenig, former CEO of MCAP noted, “The completion of the business combination in today’s market was an incredible accomplishment. This deal would not have happened without our team’s relationships within the IPO and PIPE investor community. The transaction is indicative of Monroe Capital’s franchise as a top-tier SPAC sponsor. Regardless of market conditions, Monroe Capital is able to leverage its investing platform and relationships to find exceptional companies, with top management teams, with the goal of achieving exceptional long term returns for stockholders. We look forward to continuing our position as a leading SPAC sponsor and searching for exceptional companies that can benefit from the Monroe Capital platform, including within Monroe’s relationships with the owners of the approximately 500 portfolio companies we are invested in. We are excited to continue the journey in partnering with rapidly growing, public ready companies in attractive industries.”

Zia Uddin, former Co-President of MCAP added, “We are excited to reach this historic milestone with the Company and its management team. The work we have done to date positions AdTheorent for the next stage of its growth as a public company. We believe its machine learning approach to digital advertising utilizing its privacy forward, data agnostic model makes it the performance focused DSP in the market today. We are excited about growth in the future such as the recent announcement that Q3 2021 CTV revenue was up over 300% from Q3 2020. We believe the Company’s business model is well suited for a market that is becoming increasingly complex and customers that are becoming increasingly discerning. Once again, the Monroe SPAC team executed with precision to get to the finish line with an outstanding company.”
