David Werner has acquired a 49 percent stake in 605 Third Avenue, a 1-million-square-foot office tower in Midtown Manhattan. The transaction follows a valuation of the stake at $425 million in July 2026.
Why it matters
This deal highlights significant shifts in the Manhattan commercial real estate market, as major firms seek capital amid changing interest rate conditions. It underscores Werner's continued expansion in the city after his December 2025 purchase of One Dag Hammarskjöld Plaza.
J.P. Morgan Asset Management valued the 49 percent stake in the 43-story office building at $425 million as of July 2026. This acquisition comes as the seller, Fisher Brothers, recently withdrew a planned $100 million bond offering.
