Forward-Looking Statements

This Current Report on Form 8-K and

the exhibits filed herewith include “forward-looking statements” within the meaning of the Private Securities Litigation Reform

Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,

as amended, with respect to Esquire’s and Signature’s beliefs, goals, intentions, and expectations regarding the proposed

transaction, revenues, earnings, earnings per share, loan production, asset quality, and capital levels, among other matters; our estimates

of future costs and benefits of the actions we may take; our assessments of probable losses on loans; our assessments of interest rate

and other market risks; our ability to achieve our financial and other strategic goals; the expected timing of completion of the proposed

transaction; the expected cost savings, synergies and other anticipated benefits from the proposed transaction; and other statements that

are not historical facts.

Forward-looking statements are

typically identified by such words as “believe,” “expect,” “anticipate,” “intend,” “outlook,”

“estimate,” “forecast,” “project,” “should,” and other similar words and expressions,

and are subject to numerous assumptions, risks, and uncertainties, which change over time. These forward-looking statements include, without

limitation, those relating to the terms, timing and closing of the proposed transaction.

Additionally, forward-looking statements

speak only as of the date they are made; Esquire and Signature do not assume any duty, and do not undertake, to update such forward-looking statements,

whether written or oral, that may be made from time to time, whether as a result of new information, future events, or otherwise. Furthermore,

because forward-looking statements are subject to assumptions and uncertainties, actual results or future events could differ,

possibly materially, from those indicated in such forward-looking statements as a result of a variety of factors, many of which are beyond

the control of Esquire and Signature. Such statements are based upon the current beliefs and expectations of the management of Esquire

and Signature and are subject to significant risks and uncertainties outside of the control of the parties. Caution should be exercised

against placing undue reliance on forward-looking statements. The factors that could cause actual results to differ materially include

the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties

to terminate the merger agreement; the outcome of any legal proceedings that may be instituted against Esquire or Signature; the possibility

that the proposed transaction will not close when expected or at all because conditions to the closing are not satisfied on a timely basis

or at all, or are obtained subject to conditions that are not anticipated; the ability of Esquire and Signature to meet expectations regarding

the timing, completion and accounting and tax treatments of the proposed transaction; the risk that any announcements relating to the

proposed transaction could have adverse effects on the market price of the common stock of Esquire; the possibility that the anticipated

benefits of the proposed transaction will not be realized when expected or at all, including as a result of the impact of, or problems

arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas

where Esquire and Signature do business; certain restrictions during the pendency of the proposed transaction that may impact the parties’

ability to pursue certain business opportunities or strategic transactions; the possibility that the transaction may be more expensive

to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing

business operations and opportunities; the possibility that the parties may be unable to achieve expected synergies and operating efficiencies

in the merger within the expected timeframes or at all and to successfully integrate Signature’s operations and those of Esquire;

such integration may be more difficult, time consuming or costly than expected; revenues following the proposed transaction may be lower

than expected; Esquire’s and Signature’s success in executing their respective business plans and strategies and managing

the risks involved in the foregoing; the dilution caused by Esquire’s issuance of additional shares of its capital stock in connection

with the proposed transaction; effects of the announcement, pendency or completion of the proposed transaction on the ability of Esquire

and Signature to retain customers and retain and hire key personnel and maintain relationships with their suppliers, and on their operating

results and businesses generally; risks related to the potential impact of general economic, political and market factors on the companies

or the proposed transaction and other factors that may affect future results of Esquire and Signature; and the other factors discussed

in the “Risk Factors” section of Esquire’s Annual Report on Form 10-K for the year ended December 31,

2025, in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations”

sections of Esquire’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2026, and other reports Esquire files

Joint Press Release

FOR IMMEDIATE

RELEASE

Esquire

Financial Holdings, Inc. and Signature Bancorporation Inc. Announce Final Exchange Ratio for Proposed Merger

Jericho,

NY & Rosemont, IL, June 23, 2026 – Esquire Financial Holdings, Inc. (NASDAQ: ESQ) (“Esquire”),

the parent company of Esquire Bank, National Association and Signature Bancorporation, Inc. (“Signature”), the parent company

of Signature Bank, announced today the final exchange ratio for the proposed merger based on Signature’s sale of all Schedule A

Loans.

Under

the terms of the merger agreement, Signature shareholders were to receive 2.630 shares of Esquire common stock for each share of Signature

common stock they own (the “exchange ratio”), subject to adjustment (the “merger consideration”) based on the

aggregate sale proceeds received by Signature on the sale of four loans, which loans totaled approximately $70 million (the “Schedule A

Loans”). The merger agreement provided that if any Schedule A Loans are sold prior to closing, the exchange ratio would be

adjusted based on the aggregate loan sales proceeds relative to the aggregate outstanding principal amount of such loans (the “Aggregate

Schedule A Loan Balance”), with a maximum exchange ratio of 2.80, based on the sale of all Schedule A Loans and on a

one hundred percent recovery of the Aggregate Schedule A Loan Balance, and a minimum exchange ratio of 2.50, based on a ten percent

or less aggregate recovery from the sale of the Schedule A Loans (or no sales of Schedule A Loans) prior to closing.

Based

on Signature’s Schedule A Loan sales and related recovery rate of approximately 62.0%, shares of Signature’s common stock

(except for any dissenting shares) will be converted into the right to receive 2.671 shares of Esquire stock at the close of the merger.

As disclosed in the joint proxy statement/prospectus relating to the proposed combination of Esquire and Signature dated May 6, 2026,

Esquire pro forma financial information assumed a Schedule A Loan recovery rate of 50% (included in the gross credit mark on loans) and

an associated exchange ratio of 2.630 (3.393 million Esquire shares issued to Signature shareholders), as compared to the actual recovery

rate of 62.0% and an associated exchange ratio of 2.671 (3.447 million Esquire shares issued to Signature shareholders).

“Based

upon the final exchange ratio of 2.671 as compared to the assumed exchange ratio of 2.630, Esquire will issue approximately 54 thousand,

or 1.6%, additional shares on a pro forma basis, which is reflected in the pro forma financial information and related disclosures contained

within the joint proxy statement/prospectus relating to the proposed combination of Esquire and Signature dated May 6, 2026,” stated

Andrew C. Sagliocca, Vice Chairman, CEO & President of Esquire. “We anticipate closing the proposed merger in the third quarter

of 2026.”

The

closing of the proposed merger remains subject to the approvals of Esquire stockholders and Signature shareholders and certain other

customary closing conditions.
