The value of the transaction is $247 million, subject to adjustment. Erdman will operate as a subsidiary of Cogdell Spencer Inc. The transaction is expected to close by the end of February.

By integrating Erdman's platform with Cogdell Spencer's extensive portfolio management, the company will offer the full range of healthcare real estate services to an expanded client base that includes healthcare systems, physician tenants and practice groups. The combined company will operate nationwide with offices in Atlanta, Charlotte, Charleston, S.C., Columbia, S.C., Dallas, Denver, Madison, Seattle and Washington, D.C.

“Our merger with Erdman will produce the most integrated healthcare real estate facilities firm in the nation,” said Frank C. Spencer, President and CEO of Cogdell Spencer Inc. “With over 90 years of combined experience, we will be able to provide clients with the full range of complementary, strategic services from advance planning to capital to property management.”

The merger creates a national integrated healthcare real estate company with:

Scott Ransom, President and CEO of Marshall Erdman and Associates will continue to lead Erdman, reporting to Spencer. Management will otherwise remain unchanged in both firms.

“Erdman was seeking a strategic partner in healthcare real estate and selected Cogdell Spencer, a pioneer in healthcare development, physician ownership, and asset and property management,” said Ransom. “In partnering with Cogdell Spencer, we have positioned the company for continued growth through expansion of services and strengthening of client relationships.”
