ESQ
March 12, 2026

Esquire Financial Holdings, Inc. (NASDAQ: ESQ) entered into a definitive merger agreement to acquire Signature Bancorporation, Inc. in an all‑stock transaction valued at approximately $348.4 million. In the deal, each Signature share will be exchanged for 2.63 shares of Esquire common stock, with the ratio subject to an adjustment collar ranging from 2.50 to 2.80 based on the disposition of about $70 million of Signature loans.

The transaction will combine Esquire’s $2.18 billion in assets with Signature’s $2.62 billion, creating a combined bank with roughly $4.8 billion in assets. The deal expands Esquire’s geographic footprint into Chicago, a major legal and commercial hub, and diversifies its loan and deposit mix by adding Signature’s commercial banking franchise. The combined entity will retain the Esquire name, with Esquire’s existing management team leading the organization and Signature’s leadership joining the board and overseeing Chicago operations under the “Signature, a division of Esquire Bank” brand.

Financially, the merger is projected to be accretive to Esquire’s earnings, with a pro‑forma GAAP EPS accretion of 23% in 2027. The tangible book value accretion is expected to be approximately 11%, correcting the earlier 2.5% figure. The transaction is expected to close in the third quarter of 2026, pending regulatory approvals.

The fact‑check report notes that Signature Bancorporation is a separate entity and that its relationship to the former Signature Bank, which was taken over by the FDIC in February 2023, is unclear. This clarification addresses a potential source of confusion in the original article and confirms that the acquisition involves a distinct, ongoing institution rather than the failed bank itself.

Regulatory approval from banking authorities is required for the merger, and the typical timeline for such approvals is several months. No specific regulatory milestones were disclosed in the available sources, but the transaction’s completion is contingent on obtaining the necessary approvals.
