Esquire Financial Holdings, Inc. has announced a definitive agreement to acquire Signature Bancorporation, Inc. in an all-stock transaction valued at approximately $350 million. The strategic move is designed to significantly bolster Esquire's national commercial banking platform while establishing a new and substantial operational foothold in the key Chicago market.

Company executives emphasized that the merger will create a stronger, more diversified financial institution.

The transaction, which has been unanimously approved by the boards of directors of both companies, is anticipated to close in the fourth quarter of this year, pending customary regulatory approvals and approval by Signature Bancorporation shareholders. Upon completion, the merger will solidify Esquire's position as a growing force in commercial banking, leveraging combined expertise to serve a broader national clientele from an expanded geographic network.
