Esquire Completes Signature Bancorporation Merger
The combination added a Chicago commercial-banking franchise to Esquire’s national litigation and payments businesses.
Esquire Financial Holdings, Inc. (ESQ) completed its acquisition of Signature Bancorporation, Inc., combining its national litigation and payments verticals with a commercial-banking franchise serving Chicago and the Midwest. The merger became effective Aug. 1. Financial terms and the form of consideration weren’t specified in the announcement.
The transaction gave Esquire an established presence in a market that management had identified as a priority for expansion. Before the closing, Esquire said Chicago ranked among the three largest U.S. metropolitan markets by both population and number of contingent-fee law firms, alongside New York City and Los Angeles. That concentration offered a potential bridge between Signature’s regional relationships and Esquire’s litigation-focused banking business.
“The Signature merger positions the combined company for continued industry-leading growth, performance metrics and enhanced success in the highly desirable Midwest and Chicago metropolitan markets with a well-established Chicago-based management team and brand,” Andrew C. Sagliocca, Esquire’s vice chairman, chief executive officer and president, said.
Signature Bancorporation was the parent of Signature Bank in Chicago. Its local management team and brand gave Esquire a base from which to pursue commercial clients across the metropolitan area and the broader Midwest, while Esquire brought specialized national platforms in litigation finance and payments. The combination would enhance its growth and performance metrics by joining those complementary operations.
The merger followed a series of regional-bank combinations aimed at pairing established local franchises with specialized lending or broader product capabilities. First Community Corp. agreed in 2025 to acquire Signature Bank of Georgia for about $41.6 million in stock, using the transaction to enter the Atlanta metropolitan area and add an established small-business lending platform. That deal called for Signature Bank of Georgia shareholders to receive 0.6410 First Community share for each share held and was projected to increase First Community’s earnings a share in the first year of combined operations. Eastern Bankshares separately agreed to acquire HarborOne Bancorp in a stock-and-cash transaction valued at about $490 million, strengthening its Greater Boston position while extending its footprint into Rhode Island.
For Esquire, the effective date shifted the focus from closing the transaction to linking Signature’s Chicago relationships and personnel with the buyer’s national businesses. The company’s objective is to use that regional platform to sustain growth in litigation banking, payments and commercial banking while preserving Signature’s established management team and market identity.
