TABLE OF CONTENTS

Cautionary Note Regarding Forward-Looking Statements

The statements in this quarterly report include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and other matters that are not historical facts. Examples of forward-looking statements include, among others, forecasts relating to financial and operating results or other measures of economic performance. Forward-looking statements reflect management’s current view about future events and involve risks and uncertainties that may cause actual results to differ from those expressed in the forward-looking statement or historical results. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts and often include the words or phrases such as “aim,” “can,” “may,” “could,” “predict,” “should,” “will,” “would,” “believe,” “anticipate,” “estimate,” “expect,” “hope,” “intend,” “plan,” “potential,” “project,” “will likely result,” “continue,” “seek,” “shall,” “possible,” “projection,” “optimistic,” and “outlook,” and variations of these words and similar expressions.

We have made the forward-looking statements in this quarterly report based on assumptions and estimates that we believe to be reasonable in light of the information available to us at this time. However, these forward-looking statements are subject to significant risks and uncertainties, and could be affected by many factors. Factors that could have a material adverse effect on our business, consolidated financial condition, consolidated results of operations and future growth prospects include, but are not limited to, the following:

•volatility and uncertainty facing the banking industry following the failures of several financial institutions;

•challenges related to changes in interest rates and the impact on our consolidated financial condition and consolidated results of operations;

•our ability to manage our liquidity;

•business and economic conditions nationally, regionally and in our target markets, particularly in California, which is the principal area in which we operate;

•the lack of soundness of other financial institutions;

•disruptions to the credit and financial markets, either nationally, regionally or locally;

•our dependence on the Bank for dividends;

•the possibility that we may reduce or discontinue the payments of dividends on our common stock;

•concentration of our loan portfolio in commercial loans, which loans may be dependent on the borrower’s cash flows for repayment and, to some extent, the local and regional economy;

•concentration of our loan portfolio in loans secured by real estate and changes in the prices, values and sales volumes of commercial and residential real estate;

•risks related to construction and land development lending, which involves estimates that may prove to be inaccurate and collateral that may be difficult to sell following foreclosure;

•concentration of our business activities within the geographic area of California;

•credit risks in our loan portfolio, the adequacy of our allowance for credit losses (“ACL”) and the appropriateness of our methodology for calculating such ACL;

•severe weather, natural disasters, including earthquakes, floods, droughts, and fires, particularly in California;

•our ability to manage balance sheet contraction or related revenue consideration;

•economic forecast variables that are either materially worse or better than end of quarter projections and deterioration in the economy that exceeds current consensus estimates;

• our ability to effectively manage underperforming credits;

•risks related to any future acquisitions, including transaction expenses, the potential distraction of management resources and the possibility that we will not realize anticipated benefits from any future acquisitions;

•interest rate shifts and its impact on our consolidated financial condition and consolidated results of operation;

•disruptions to the credit and financial markets, either nationally or globally;

•competition in the banking industry, nationally, regionally or locally;

•failure to maintain adequate liquidity and regulatory capital and comply with evolving federal and state banking regulations;

•inability of our risk management framework to effectively mitigate credit risk, interest rate risk, liquidity risk, price risk, compliance risk, technology risk, operational risk, strategic risk and reputational risk;

•our dependence on our management and our ability to attract and retain experienced and talented bankers;

•failure to keep pace with technological change or difficulties when implementing new technologies;

•system failures, data security breaches, including as a result of cyber-attacks, or failures to prevent breaches of our network security;

•our reliance on communications and information systems to conduct business and reliance on third parties and their affiliates to provide key components of business structure, any disruptions of which could interrupt operations or increase the costs of doing business;

•fraudulent and negligent acts by our customers, employees or vendors;

•our ability to prevent or detect all errors or fraud with our financial reporting controls and procedures;

•increased loan losses or impairment of goodwill and other intangibles;

•an inability to raise necessary capital to fund our growth strategy, operations, or to meet increased minimum regulatory capital levels;

•the sufficiency of our capital, including sources of such capital and the extent to which capital may be used or required;

•the institution and outcome of litigation and other legal proceedings to which we become subject;

•examinations by our regulatory authorities, including the possibility that the regulatory authorities may, among other things, require us to increase our allowance for credit losses, slow the growth of our commercial real estate loans or write-down assets, or otherwise impose restrictions or conditions on our operations, including, but not limited to, our ability to acquire or be acquired;

•our status as an emerging growth company, which reduces our disclosure obligations under the federal securities laws compared to other publicly traded companies;

•the impact of current and future governmental monetary and fiscal policies, such as the implementation of tariffs and counter-tariffs; and

•other factors and risks described in this quarterly report and from time to time in other documents that we file or furnish with the Securities and Exchange Commission (“SEC”), including, without limitation, the risks described under Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2025, that was filed with the SEC on March 13, 2026.

Because of these risks and other uncertainties, our actual results, performance or achievement, or industry results, may be materially different from the anticipated or estimated results discussed in the forward-looking statements in this quarterly report. Our past results of operations are not necessarily indicative of our future results. You should not rely on any forward-looking statements, which represent our beliefs, assumptions and estimates only as of the dates on which they were made, as predictions of future events. We undertake no obligation to update these forward-looking statements, even though circumstances may change in the future, except as required under federal securities law. We qualify all of our forward-looking statements by these cautionary statements.
