Altus Group announces leadership transition

Jim Hannon is departing the Company as Chief Executive Officer (“CEO”) and Director, effective immediately. Mike Gordon, Altus Group’s former CEO and Director since 2020, has been appointed Executive Chair, effective immediately, and has agreed to assume the CEO role in Q1 2026. Concurrently, Raymond Mikulich is stepping down from the Chair role and remaining on the Board as a Director. The Chair transition is part of the Board’s commitment to succession planning and ongoing refreshment.

Mr. Gordon stated: “On behalf of the Board, I’d like to thank Jim for his vision, dedication, and tireless efforts over the years. He has played an integral role positioning Altus Group for the opportunity as a pure-play data and analytics platform. As Altus Group enters its next growth phase, our focus shifts from operational build out to accelerating market adoption of our new product innovations, making this the right time for a leadership change that aligns with Altus Group’s future needs.

We’re also very grateful to Ray for having stewarded the Company through one of its most pivotal decades amid a period of profound change in the CRE industry. During Ray’s tenure as Chair, the Company’s long-standing shareholders have witnessed a deliberate evolution of the Company’s strategy and transformation from its professional services roots into a leading CRE intelligence firm. I look forward to carrying the momentum forward and accelerating the pace of progress as I step into the role.”

Mr. Mikulich added: “I am gratified by the success we have achieved as the Company is now realigned as a focused software and analytics business. With that transition largely completed, I believe it is time for new leadership and I am confident and fully supportive of Mike Gordon, a highly regarded data and analytics executive with a proven track record of value creation.”

Strategic Review Update

The Board undertook a disciplined and thorough strategic review process, as it periodically does, to evaluate all potential options for maximizing shareholder value. The Company engaged in a fulsome review, which included a consideration of a wide spectrum of strategic alternatives – including soliciting interest from potential acquirers.

After careful consideration of the alternatives, including reviewing multiple proposals, the Board determined that remaining independent and continuing to execute and accelerate its strategy is the best path forward for Altus Group and to maximize value for its shareholders.

The Company has undergone significant business transformation in recent years to operate more efficiently and transition into a pure-play CRE data and analytics platform. Altus Group is in the early stages of a new

product cycle, as market conditions strengthen and the benefits of its operational and strategic transformation are beginning to take hold. The Board believes these factors present considerable upside potential for the Company’s shareholders in the periods ahead.

Mr. Gordon added: “The strategic review gave us tremendous insight and reinforced confidence in our value creation plan. We came away with clear priorities and strengthened conviction on what needs to be done and how we need to execute to accelerate our momentum. I’m personally energized to be re-engaging in the business at such an exciting inflection point.”

The Company will provide further details of its value creation plan at its upcoming Investor Day on November 20, 2025.
