RESULTS OF OPERATIONS (Q2 2026 vs. Q1 2026, unless otherwise noted):

Net Interest Income

Net interest income was up by $1.3 million, or 3%, and NIM was up by 10 basis points. Compared to the second quarter of 2025, net interest income was up by $4.6 million, or 12%, and NIM was up by 37 basis points.

•As of May 1, 2026, the remaining deferred loss from a previously terminated cash flow hedge was fully amortized, eliminating this expense from the Bank's ongoing run rate. The second quarter reflected approximately two months of benefit from the cessation of this amortization, contributing $1.4 million to net interest income and 9 basis points to NIM. Beginning in third quarter, there will be no amortization expense and the Bank’s results will reflect a permanent improvement to its earnings and margin run rate.

•Average interest-earning assets decreased by $95 million, and the yield was up by 4 basis points.

•Average interest-bearing liabilities decreased by $122 million, and the rate was down by 5 basis points.

•Salaries and employee benefits expense increased by $972 thousand, or 4%, reflecting staffing additions in our commercial and retail banking business lines, as well as volume- and performance-related compensation changes.

Forward-Looking Statements

This press release contains statements that are “forward-looking statements.” We may also make forward-looking statements in other documents we file with the U.S. Securities and Exchange Commission ("SEC"), in our annual reports to shareholders, in press releases and other written materials, and in oral statements made by our officers, directors, or employees. You can identify forward-looking statements by the use of the words “believe,” “expect,” “anticipate,” “intend,” “estimate,” “assume,” “outlook,” “will,” “should,” and other expressions that predict or indicate future events and trends and which do not relate to historical matters. You should not rely on forward-looking statements, because they involve known and unknown risks, uncertainties, and other factors, some of which are beyond our control. These risks, uncertainties, and other factors may cause our actual results, performance, or achievements to be materially different from the anticipated future results, performance, or achievements expressed or implied by the forward-looking statements.

Some of the factors that might cause these differences include the following:

•changes in general business and economic conditions (including the impact of ongoing armed conflicts, tariffs, inflation, future U.S government shutdowns, and concerns about liquidity) on a national basis and in the local markets in which we operate;

•interest rate changes or volatility, as well as changes in the balance and mix of loans and deposits;

•changes in customer behavior due to political, business and economic conditions;

•changes in loan demand and collectability;

•the possibility that future credit losses are higher than currently expected due to changes in economic assumptions or adverse economic developments;

•ongoing volatility in national and international financial markets;

•reductions in the market value or outflows of wealth management assets under administration;

•decreases in the value of securities and other assets;

•increases in defaults and charge-off rates;

•changes in the size and nature of our competition;

•changes in, and evolving interpretations of, existing and future laws, rules and regulations;

•changes in accounting principles, policies and guidelines;

•operational risks including, but not limited to, changes in information technology, cybersecurity incidents, fraud, natural disasters, war, terrorism, civil unrest and future pandemics;

•regulatory, litigation and reputational risks; and

•changes in the assumptions used in making such forward-looking statements.

In addition, the factors described under “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as updated by our Quarterly Reports on Form 10-Q and other filings submitted to the SEC, may result in these differences. You should carefully review all of these factors, and you should be aware that there may be other factors that could cause these differences. The forward-looking statements in this report were based on information, plans, and estimates at the date of this report, and we assume no obligation to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events or other changes.

Supplemental Information - Explanation of Non-GAAP Financial Measures

In addition to results presented in accordance with generally accepted accounting principles (“GAAP”), this press release contains certain non-GAAP financial measures. Washington Trust's management believes that the supplemental non-GAAP information, such as adjusted noninterest income, adjusted noninterest expense, adjusted income before income taxes, adjusted income tax expense, adjusted net income, adjusted diluted earnings per common share, adjusted return on average assets, adjusted return on average equity, and adjusted efficiency ratio, as well as measurements and ratios based on tangible equity and tangible assets, is utilized by regulators and market analysts to evaluate a company's financial condition and therefore, such information is useful to investors. These disclosures should not be viewed as a substitute for financial results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures, which may be presented by other companies. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names.

The following tables present daily average balance, interest, and yield/rate information, as well as net interest margin on an FTE basis. Tax-exempt income is converted to an FTE basis using the statutory federal income tax rate. Unrealized gains (losses) on available for sale securities, changes in fair value on mortgage loans held for sale, and basis adjustments associated with fair value hedges are excluded from the average balance and yield calculations. Nonaccrual loans are included in amounts presented for loans. Interest income attributable to nonaccrual loans is included in accordance with accounting policy as disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025.
