Ukrainian fertilizer billionaire Alex Rovt has recapitalized the iconic 14 Wall St. Sources said the deal closed yesterday, leaving Josh Zamir’s Capstone Equities as the managing partner while replacing the Carlyle Group in the venture.

The property was marketed by Adam Spies and Douglas Harmon of Eastdil Secured, who sold the landmarked former Bankers Trust Building twice before. Robert Verrone of Ironhound was instrumental in the restructuring.

The pyramid-topped 1 million square-foot tower is now revalued at about $300 million. The capital influx has also reduced its mortgage by $75 million, to $255 million, sources said. None of the parties could be reached for comment.
