Ally Bridge Group has committed to a new long-term headquarters lease at 560 Lexington, an office tower owned by Rudin in the Plaza District. The global investment management firm, which focuses on healthcare and life science innovation, will relocate its U.S. headquarters to the property in early 2027.
The lease covers 6,440 square feet on a portion of the building’s 18th floor. The agreement runs for 10 years and 10 months, providing the tenant with a nearly eleven-year runway at the Plaza District tower. Ally Bridge is moving from its current offices at 430 Park Ave., consolidating its U.S. headquarters operations into the new space.
Rudin describes 560 Lexington as a 22-story office building totaling 380,000 square feet. The Plaza District location is a longstanding destination for financial and investment firms, and the new lease continues that pattern by bringing a global investment manager focused on healthcare and life sciences into the tenant roster.
In commenting on the transaction, Kevin Daly, vice president of office leasing at Rudin, said that Ally Bridge Group’s long-term commitment underscores the Plaza District and 560 Lexington’s ongoing appeal to the global investment community. The combination of a long lease term and a headquarters relocation signals a durable space requirement rather than a short-term or opportunistic move.
On the tenant representation side, Ally Bridge was advised by a CBRE team that included Sinclair Li, Conor Kenny and Connor DeSimone. Rudin was represented in-house by Daly and also worked with a CBRE team consisting of Peter Turchin, Brett Shannon, Eric Deutsch, Jacob Rosenthal and Lauren Levy. The involvement of multiple brokerage professionals reflects the complexity and importance of structuring a headquarters lease with a long term.
The transaction adds a specialized investment firm to the tenant mix at 560 Lexington while reinforcing the Plaza District’s role as a hub for global capital and financial services. With Ally Bridge’s relocation scheduled for early 2027, both landlord and tenant have a defined timeline to execute build-out and transition plans to support the firm’s U.S. headquarters operations in the new space.
