Domain will expand its role from adviser to owner

Domain Capital Group today announced it has closed on the acquisition of Denver-based Simpson Property Group (“Simpson”) from The State of Michigan Retirement Systems (“SMRS”). Simpson is a fully integrated real estate firm providing services in commercial and multifamily property management, development and construction.

Domain’s relationship with Simpson spans more than three decades. Senior executives at Domain first began advising Simpson more than 30 years ago during their time at PwC. Since 2008, Domain has served as investment advisor, overseeing Simpson’s operations and investment strategy on behalf of SMRS. Through this long-standing partnership, Domain has worked closely with Simpson’s executive leadership to support portfolio growth, capital allocation and operational performance across its multifamily platform.

With the acquisition, Domain expands its role from advisor to owner, positioning the firm to further institutionalize and scale Simpson’s vertically integrated multifamily investment and operating platform. It also reinforces Domain’s commitment to growing its own real estate platform through high-quality, vertically integrated operating businesses with strong institutional pedigrees.

“We are incredibly excited to formalize what has already been a deeply integrated and successful partnership,” said Patrick Leardo, CEO of Domain Capital Group. “We are grateful for the trust The State of Michigan Retirement Systems has placed in Domain over many years and appreciative of the collaboration with Simpson’s leadership team. This transaction reflects our shared confidence in the platform and its long-term growth trajectory.”

Simpson Property Group CEO Frank Rooney Jr. added, “We are thrilled to be working even more closely with Domain as we enter this next chapter of growth. Its long-standing involvement with our platform provides continuity and alignment, and we look forward to expanding our investment capabilities while continuing to deliver exceptional service to our residents and institutional investors.”

Domain intends to work alongside Simpson’s executive team to expand institutional investment offerings, including new commingled fund vehicles and separately managed accounts for institutional investors. Building on Simpson’s existing institutional partnerships, Domain will seek to enhance capital formation capabilities, broaden investor access and support continued portfolio expansion across targeted U.S. markets.

Simpson will continue to operate under its established brand and disciplined investment philosophy, led by Rooney and the existing executive team. Day-to-day operations are expected to continue uninterrupted. Domain’s acquisition is expected to provide additional strategic resources, capital flexibility and long-term alignment to support growth initiatives.
