Summary · why it matters

An entity tied to Chicago financial services firm Mesirow bought the Amgen office complex in Deerfield in a sale-leaseback deal for $151 million. The property spans 660,000 square feet of office space in three buildings at 1 Horizon Way along I-294, on a 70-acre site that Crain's calls rare for its size. Amgen will remain in one of the three buildings, while Fortune Brands Innovations occupies the other two. Amgen acquired the campus through its 2023 acquisition of Horizon Therapeutics, which bought the 70-acre site in 2020 from Japan-based Takeda Pharmaceuticals for $115 million. The price spiked in 2025 after Amgen brought on Fortune Brands, which said it would get up to 1,000 employees working at the site by 2027. Mesirow's bespoke real estate subsidiary specializes in sale-leasebacks and has completed upwards of $8 billion worth of transactions in the past three decades, though it is unclear whether that venture was involved in this deal.
