New York-based National Holdings Corporation, an independent brokerage firm, announced on Tuesday that it will acquire Winslow, Evans & Crocker, Inc., an employee-owned full-service investment firm.

The transaction is expected to close in the first fiscal quarter of 2020, according to a Nationall Holdings press release. Terms of the deal were not disclosed.

The acquisition is expected to add to National’s gross and adjusted EBITDA margins, the release said.

Boston-based Winslow, Evans & Crocker, established in 1991, employs more than 50 financial professionals overseeing $2.5 billion in assets under management.

“National shares our culture and commitment to our clients and we believe this acquisition is a natural combination that delivers superior and immediate value to National and Winslow,” said chairman Tina Maloney.

Michael Mullen, National Holdings chairman and CEO, said the firms share many key values, importantly sharing in the ‘Client-first’ culture.

“This acquisition aligns well with our corporate goals and is a strong strategic and cultural fit," he said. "We look forward to expanding our presence in the Boston area and are pleased to be doing so with such a like-minded firm.”
