WASHINGTON TRUST BANCORP INC

Note 1 -Basis of Presentation

Nature of Operations

The Bancorp is a publicly-owned registered bank holding company that has elected to be a financial holding company. The Bancorp’s principal subsidiary is the Bank, a Rhode Island chartered financial institution founded in 1800. The Bank is the oldest community bank in the nation and the largest state-chartered bank headquartered in Rhode Island.

Washington Trust offers a full range of financial services, including commercial, residential, and consumer lending, retail and commercial deposit products, and wealth management and trust services through its offices in Rhode Island, Massachusetts, and Connecticut.

Basis of Presentation

The accounting and reporting policies of Washington Trust conform to GAAP and to general practices of the banking industry.

The Corporation’s Unaudited Consolidated Financial Statements include the accounts of the Bancorp and its wholly-owned subsidiaries, except subsidiaries that are not deemed necessary to be consolidated. Through consolidation, intercompany balances and transactions have been eliminated.

The Unaudited Consolidated Financial Statements of the Corporation presented herein have been prepared pursuant to the rules of the SEC for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying Unaudited Consolidated Financial Statements have been included. Interim results are not necessarily indicative of the results of the entire year. The accompanying Unaudited Consolidated Financial Statements should be read in conjunction with the Audited Consolidated Financial Statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

Use of Estimates

In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ from those estimates. Management considers the ACL on loans to be a material estimate that is particularly susceptible to change.

Note 2 -Recently Issued Accounting Pronouncements

Accounting Standards Adopted in 2026

Financial Instruments - Credit Losses - Topic 326

Accounting Standards Update No. 2025-05, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets” (“ASU 2025-05”) was issued in July 2025 to introduce a practical expedient intended to simplify the estimation of expected credit losses on current accounts receivable and contract assets arising from revenue transactions under ASC 606. The practical expedient permits entities to assume that current conditions as of the reporting date remain unchanged for the remaining life of the asset. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, including interim periods within those fiscal years, with early adoption permitted. The Corporation adopted the provisions of ASU 2025-05 on a prospective basis. The adoption of ASU 2025-05 did not have a material impact on the Corporation’s financial statements.

Accounting Standards Pending Adoption

Income Statement - Reporting Comprehensive Income - Subtopic 220

Accounting Standards Update No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) - Disaggregation of Income Statement Expenses” (“ASU 2024-03”), was issued in November 2024 to enhance and provide additional disclosure on certain costs and expenses. The effective date of ASU 2024-03 was further clarified in ASU 2025-01, which was subsequently issued in January 2025. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The provisions under ASU 2024-03 can be applied on either a prospective or retrospective basis. The Corporation is currently evaluating the impact of this ASU and does not expect the adoption to have a material impact on its financial statements.

Intangibles - Goodwill and Other - Internal-Use Software - Subtopic 350

Accounting Standards Update No. 2025-06, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”) was issued in September 2025 to modernize the accounting framework for internal-use software development costs to better reflect contemporary development practices. ASU 2025-06 eliminates the previous stage-based model (i.e., preliminary, application development, and post-implementation stages) and introduces a principles-based capitalization model. Under this ASU, software development costs are capitalized when management has authorized and committed to funding the project, and it is probable that the project will be completed and the software will perform its intended function. The ASU also consolidates guidance for website development costs into ASC 350-40 and aligns disclosure requirements with those under ASC 360-10, including the nature and amount of capitalized internal-use software costs, the accounting policy and capitalization criteria, any significant judgments and estimates applied, amortization methods and useful lives, and qualitative and quantitative information about major software projects. ASU 2025-06 is effective for annual reporting periods beginning after December 15, 2027, including interim periods within those annual periods, with early adoption permitted. The provisions under ASU 2025-06 can be applied on either a prospective, modified retrospective, or full retrospective basis. The Corporation is currently evaluating the impact of this ASU and does not expect the adoption to have a material impact on its financial statements.

Derivatives and Hedging - Topic 815

Accounting Standards Update No. 2025‑09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements” (“ASU 2025-09”) was issued in November 2025 to make targeted amendments to the hedge accounting guidance to better align accounting outcomes with an entity’s risk management activities and to clarify certain aspects of the guidance originally amended by ASU 2017‑12. The amendments primarily affect cash flow hedges, but also include limited changes related to fair value hedges and net investment hedges. Among other things, ASU 2025-09 expands the ability to hedge groups of forecasted transactions with similar risk exposures, provides a framework to facilitate hedge accounting for forecasted interest payments on variable‑rate debt instruments that permit changes to the reference rate and tenor, clarifies hedge accounting for forecasted purchases and sales of nonfinancial assets, updates guidance related to net written options used as hedging instruments, and addresses certain recognition and presentation matters involving foreign currency‑denominated debt used in multiple hedging relationships. ASU 2025-09 is effective for annual reporting periods beginning after December 15, 2026, and interim periods within those periods, with early adoption permitted. The amendments are required to be applied on a prospective basis, with transition provisions that allow certain hedging relationships to continue without de-designation. The Corporation is currently evaluating the impact of this ASU and does not expect the adoption to have a material impact on its financial statements.

Interim Reporting - Topic 270

Accounting Standards Update No. 2025‑11, “Interim Reporting (Topic 270): Narrow‑Scope Improvements” (“ASU 2025-11”) was issued in December 2025 to clarify the scope and applicability of interim reporting guidance, reorganize and clarify interim disclosure requirements, and introduce a disclosure principle requiring entities to disclose events occurring since the end of the most recent annual reporting period that have a material impact on the entity. The amendments are intended to improve clarity and consistency in interim reporting and do not change the underlying recognition or measurement requirements under U.S. GAAP. ASU 2025‑11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The amendments can either be applied on a prospective or retrospective basis. ASU 2025-11 is not expected to have a material impact on the Corporation’s financial statements.

Note 3 -Securities

Available for Sale Debt Securities

The following tables present the amortized cost, gross unrealized holding gains, gross unrealized holding losses, ACL on securities, and fair value of securities by major security type and class of security:

Available for sale debt securities balances exclude accrued interest receivable of $3.0 million and $3.1 million, respectively, as of September 30, 2026 and December 31, 2025.

At September 30, 2026 and December 31, 2025, securities with a fair value of $357.9 million and $392.4 million, respectively, were pledged as collateral for FHLB borrowings, potential borrowings with the FRBB, certain public deposits, and for other purposes. See Note 9 for additional discussion on FHLB borrowings.

The schedule of maturities of available for sale debt securities is presented below. Mortgage-backed securities are included based on weighted average maturities, adjusted for anticipated prepayments. All other debt securities are included based on contractual maturities. Actual maturities may differ from amounts presented because certain issuers have the right to call or prepay obligations with or without call or prepayment penalties.

-12-

Included in the above table are debt securities with an amortized cost balance of $44.7 million and a fair value of $41.9 million at September 30, 2026 that are callable at the discretion of the issuers. Final maturities of the callable securities range from 7 months to 18 years, with call features ranging from 1 month to 7 years.

Assessment of Available for Sale Debt Securities for Impairment

Management assesses the decline in fair value of investment securities on a regular basis. Unrealized losses on debt securities may occur from current market conditions, increases in interest rates since the time of purchase, a structural change in an investment, volatility of earnings of a specific issuer, or deterioration in credit quality of the issuer. Management evaluates both qualitative and quantitative factors to assess whether an impairment exists.

The following tables summarize available for sale debt securities in an unrealized loss position, for which an ACL on securities has not been recorded, segregated by length of time that the securities have been in a continuous unrealized loss position:

-13-

There were no debt securities on nonaccrual status at September 30, 2026 and 2025 and, therefore there was no accrued interest related to debt securities reversed against interest income for the three and nine months ended September 30, 2026 and 2025.

As of September 30, 2026, management does not intend to sell, and it is not more-likely-than-not that the Corporation will be required to sell, any of the debt securities in an unrealized loss position before the recovery of its amortized cost basis. As further described below, management believes the unrealized losses on these debt securities are primarily attributable to changes in the investment spreads and interest rates, and not due to reasons of credit quality. Therefore, no ACL was recorded at both September 30, 2026 and December 31, 2025.

Obligations of U.S. Government Agency and U.S. Government-Sponsored Enterprise Securities, including Mortgage-Backed Securities

The contractual cash flows for these securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. The issuers of these securities continue to make timely principal and interest payments, and none of these securities were past due at September 30, 2026. Additionally, the Corporation utilizes a zero credit loss estimate for these securities.

Individual Name Issuer Trust Preferred Debt Securities

These securities in an unrealized loss position at September 30, 2026 includedtwo trust preferred securities issued bytwo individual companies in the banking sector. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of September 30, 2026, there wasone individual name issuer trust preferred debt security with an amortized cost of $2.0 million and unrealized losses of $37 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between September 30, 2026 and the filing date of this report. Based on the information available through the filing date of this report, all individual name issuer trust preferred debt securities continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers.

Corporate Bonds

These securities in an unrealized loss position at September 30, 2026 included three corporate bond holdings issued bytwo individual companies in the financial services industry. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of September 30, 2026, there wereno corporate bond debt securities that were rated below investment grade by S&P. We noted no downgrades to below investment grade between September 30, 2026 and the filing date of this report. Based on the information available through the filing date of this report, all corporate bond debt securities continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers.

Note 4 -Loans

The following table presents the carrying value of loans, segregated by class of loans:

(1)CRE consists of commercial mortgages primarily secured by non-owner occupied income-producing property, as well as construction and development loans. Construction and development loans are made to businesses for land development or the on-site construction of industrial, commercial, or residential buildings.

(2)C&I consists of loans to businesses and individuals, a portion of which are fully or partially collateralized by owner occupied real estate.

(3)Residential real estate consists of mortgage and homeowner construction loans secured by one- to four-family residential properties. Also, includes negative basis adjustments associated with fair value hedges of $2.2 million and $335 thousand, respectively, at September 30, 2026 and December 31, 2025. See Note 6 for additional disclosure.

(4)Other consists of loans to individuals secured by general aviation aircraft and other personal installment loans.

(5)Includes net unamortized loan origination costs of $11.3 million and $11.0 million, respectively, at September 30, 2026 and December 31, 2025 and net unamortized premiums on loans purchased from and serviced by other financial institutions of $181 thousand and $198 thousand, respectively, at September 30, 2026 and December 31, 2025.

The carrying value of loans excludes accrued interest receivable of $20.4 million and $20.1 million, respectively, as of September 30, 2026 and December 31, 2025.

As of September 30, 2026 and December 31, 2025, loans amounting to $2.8 billion and $2.9 billion, respectively, were pledged as collateral to the FHLB under a blanket pledge agreement and to the FRBB for the discount window. See Note 9 for additional disclosure regarding borrowings.

Concentrations of Credit Risk

A significant portion of our loan portfolio is concentrated among borrowers in southern New England, and a substantial portion of the portfolio is collateralized by real estate in this area. The ability of single family residential and consumer borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the market area and real estate values. The ability of commercial borrowers to honor their repayment commitments is dependent on the general economy, as well as the health of the real estate economic sector in the Corporation’s market area.

-15-

Past Due Loans

Past due status is based on the contractual payment terms of the loan. The following tables present an aging analysis of past due loans, segregated by class of loans:

Included in past due loans as of September 30, 2026 and December 31, 2025, were nonaccrual loans of $15.0 million and $8.3 million, respectively. In addition, all loans 90 days or more past due at September 30, 2026 and December 31, 2025 were classified as nonaccrual.

Nonaccrual Loans

Loans, with the exception of certain well-secured loans that are in the process of collection, are placed on nonaccrual status and interest recognition is suspended when such loans are 90 days or more overdue with respect to principal and/or interest, or sooner if considered appropriate by management. Well-secured loans are permitted to remain on accrual status provided that full collection of principal and interest is assured and the loan is in the process of collection. Loans are also placed on nonaccrual status when, in the opinion of management, full collection of principal and interest is doubtful. When loans are placed on nonaccrual status, interest previously accrued but not collected is reversed against current period income. Subsequent interest payments received on nonaccrual loans are applied to the outstanding principal balance of the loan or recognized as interest income depending on management’s assessment of the ultimate collectability of the loan. Loans are removed from nonaccrual status when they have been current as to principal and interest (generally for six months), the borrower has demonstrated an ability to comply with repayment terms, and when, in management’s opinion, the loans are considered to be fully collectible.

-16-

The following table is a summary of nonaccrual loans, segregated by class of loans:

Nonaccrual loans of $9.6 million and $4.6 million, respectively, at September 30, 2026 and December 31, 2025 were current as to the payment of principal and interest.

As of September 30, 2026 and December 31, 2025, nonaccrual loans secured by one- to four-family residential properties amounting to $2.6 million and $3.0 million, respectively, were in process of foreclosure.

Troubled Loan Modifications

A loan that has been modified is considered a TLM when the modification is made to a borrower experiencing financial difficulty and the modification has a direct impact to the contractual cash flows. If both of the aforementioned criteria are met, then the modification is considered a TLM and subject to the enhanced disclosure requirements.

In the course of resolving problem loans, the Corporation may choose to modify the contractual terms of loans to borrowers who are experiencing financial difficulty. Such modifications to borrowers experiencing financial difficulty may include modified contractual terms that have a direct impact to contractual cash flows, including principal forgiveness, interest rate reductions, maturity extensions, other-than-insignificant payment delays, or any combination thereof. Debt may be bifurcated with separate terms for each tranche of the TLM. Executing a TLM in lieu of aggressively enforcing the collection of the loan may benefit the Corporation by increasing the ultimate probability of collection.

Nonaccrual loans that become TLMs remain on nonaccrual status for a period (generally six months) of satisfactory payment performance, either immediately before or after the modification, before the loan is returned to accrual status. If a TLM is on accrual status prior to being modified, it is reviewed to determine if the modified loan should remain on accrual status.

If the TLM successfully meets all repayment terms according to the modification documents for a specified period of time (generally 12 months) and the borrower is no longer experiencing financial difficulty, it would be declassified from TLM status.

As of September 30, 2026 and December 31, 2025, the carrying value of TLMs amounted to $26.3 million and $8.2 million, respectively.

-17-

The following table presents the carrying value at September 30, 2026, of TLMs made during the three months and nine months ended September 30, 2026, segregated by class of loans and type of concession granted:

(1)Combination includes an interest rate reduction, maturity extension and other-than-insignificant payment delay.

(2)Percentage of TLMs to the total loans outstanding within the respective loan class.

The following tables present the carrying value at September 30, 2025 of TLMs made during the periods indicated, segregated by class of loans and type of concession granted:

(1)Percentage of TLMs to the total loans outstanding within the respective loan class.

(1)Percentage of TLMs to the total loans outstanding within the respective loan class.

The following tables describe the financial effect of TLMs made during the periods indicated, segregated by class of loans:

-18-

Management closely monitors the performance of TLMs to understand the effectiveness of the modifications. As of the dates indicated, the following tables present an aging analysis of TLMs that have been modified in the past 12 months:

At both September 30, 2026 and September 30, 2025, there wereno TLMs made in the previous 12 months for which there was a subsequent payment default.

Commitments to lend additional funds to borrowers experiencing financial difficulty whose loans were modified as TLMs were not significant. In certain limited circumstances, borrowers experiencing financial difficulty may have access to committed but unused borrowing capacity.

Individually Analyzed Loans

As of September 30, 2026, individually analyzed loans include nonaccrual commercial loans, nonaccrual TLMs, as well as certain other loans based on the underlying risk characteristics and the discretion of management to individually analyze such loans. Prior to this date, individually analyzed loans also included accruing TLMs.

As of September 30, 2026 and December 31, 2025, the carrying value of individually analyzed loans amounted to $14.1 million and $8.9 million, respectively.

The carrying value of collateral dependent individually analyzed loans was $13.9 million and $7.5 million, respectively, at September 30, 2026 and December 31, 2025. For collateral dependent loans where management has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and repayment of the loan is to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. See Note 7 for additional disclosure regarding fair value of individually analyzed collateral dependent loans.

-19-

The following table presents the carrying value of collateral dependent individually analyzed loans:

(1)Secured by income-producing property.

(2)Secured by business assets.

(3)Secured by one- to four-family residential properties.

Credit Quality Indicators

Commercial

The Corporation utilizes an internal rating system to assign a risk to each of its commercial loans. Loans are rated on a scale of 1 to 10. This scale can be assigned to three broad categories including “pass” for ratings 1 through 6, “special mention” for 7-rated loans, and “classified” for loans rated 8, 9 or 10. Additionally, ratings 7 through 10 are considered criticized, as defined by regulatory agencies. The loan risk rating system takes into consideration parameters including the borrower’s financial condition, the borrower’s performance with respect to loan terms, the adequacy of collateral, the adequacy of guarantees, and other credit quality characteristics. The Corporation takes the risk rating into consideration along with other credit attributes in the establishment of an appropriate ACL on loans. See Note 5 for additional information.

A description of the commercial loan categories is as follows:

Pass - Loans with acceptable credit quality, defined as ranging from superior or very strong to a status of lesser stature. Superior or very strong credit quality is characterized by a high degree of cash collateralization or strong balance sheet liquidity. Lesser stature loans have an acceptable level of credit quality, but may exhibit some weakness in various credit metrics such as collateral adequacy, cash flow, performance or may be in an industry or of a loan type known to have a higher degree of risk. These weaknesses may be mitigated by secondary sources of repayment, including SBA guarantees.

Special Mention - Loans with potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Bank’s position as creditor at some future date. Special Mention assets are not adversely classified and do not expose the Bank to sufficient risk to warrant adverse classification. Examples of these conditions include but are not limited to outdated or poor quality financial data, strains on liquidity and leverage, losses or negative trends in operating results, marginal cash flow, weaknesses in occupancy rates or trends in the case of commercial real estate, and frequent delinquencies.

Classified - Loans identified as “substandard,” “doubtful” or “loss” based on criteria consistent with guidelines provided by banking regulators. A “substandard” loan has defined weaknesses which make payment default or principal exposure likely, but not yet certain. Such loans are apt to be dependent upon collateral liquidation, a secondary source of repayment or an event outside of the normal course of business. The loans are closely watched and are either already on nonaccrual status or may be placed on nonaccrual status when management determines there is uncertainty of collectability. A “doubtful” loan is placed on nonaccrual status and has a high probability of loss, but the extent of the loss is difficult to quantify due to dependency upon collateral having a value that is difficult to determine or upon some near-term event which lacks certainty. A loan in the “loss” category is considered generally uncollectible or the timing or amount of payments cannot be

-20- determined. “Loss” is not intended to imply that the loan has no recovery value, but rather, it is not practical or desirable to continue to carry the asset.

The Corporation’s procedures call for loan risk ratings and classifications to be revised whenever information becomes available that indicates a change is warranted. On a quarterly basis, management reviews a watched asset list, which generally consists of commercial loans that are risk-rated 6 or worse, highly leveraged transaction loans, high-volatility commercial real estate, and other selected loans. Management’s review focuses on the current status of the loans, the appropriateness of risk ratings and strategies to improve the credit.

An annual credit review program is conducted by a third party to provide an independent evaluation of the creditworthiness of the commercial loan portfolio, the quality of the underwriting and credit risk management practices, and the appropriateness of the risk rating classifications. This review is supplemented with selected targeted internal reviews of the commercial loan portfolio.

Residential and Consumer

Management monitors the relatively homogeneous residential real estate and consumer loan portfolios on an ongoing basis using delinquency information by loan type.

In addition, other techniques are utilized to monitor indicators of credit deterioration in the residential real estate loans and home equity consumer loans. Among these techniques is the periodic tracking of loans with an updated Fair Isaac Corporation (commonly known as “FICO”) score and an updated estimated LTV ratio. LTV is estimated based on such factors as geographic location, the original appraised value, and changes in median home prices, and takes into consideration the age of the loan. The results of these analyses and other credit review procedures, including selected targeted internal reviews, are taken into account in the determination of qualitative loss factors for residential real estate and home equity consumer credits.

Washington Trust may renew commercial loans at or immediately prior to their maturity. In the tables below, renewals subject to full credit evaluation before being granted are reported as originations in the period renewed. Loans with extensions of maturity dates of more than three months, including TLMs, are reported as originations in the period extended. Gross charge-offs are reported in the loan’s initial origination year.

The following table includes information on credit quality indicators and gross charge-offs for the Corporation’s loan portfolio, segregated by class of loans as of September 30, 2026:

(1)Excludes a $2.2 million negative basis adjustment associated with fair value hedges. See Note 6 for additional disclosure.

-23-

Note 5 -Allowance for Credit Losses on Loans

The ACL on loans is management’s estimate of expected lifetime credit losses on loans carried at amortized cost. The level of the ACL on loans is based on management’s ongoing review of all relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts.

The following table presents the activity in the ACL on loans for the three months ended September 30, 2026:

The following table presents the activity in the ACL on loans for the nine months ended September 30, 2026:

The following table presents the activity in the ACL on loans for the three months ended September 30, 2025:

The following table presents the activity in the ACL on loans for the nine months ended September 30, 2025:

For the purpose of estimating the ACL, management segregated the loan portfolio into the portfolio segments detailed in the above tables. Each of these segments possesses unique risk characteristics that are considered when determining the

-24- appropriate level of ACL for each segment. Some of the characteristics unique to each loan category include:

Commercial Loans

CRE loans consist of commercial mortgages secured by non-owner occupied real property where the primary source of repayment is derived from rental income associated with the property or the proceeds of the sale, refinancing or permanent financing of the property. CRE loans also include construction loans made to businesses for land development or the on-site construction of industrial, commercial or residential buildings. CRE loans frequently involve larger loan balances to single borrowers or groups of related borrowers. Washington Trust’s commercial real estate loans are secured by a variety of property types, such as multi-family, retail, industrial and warehouse, hospitality, office, as well as other specific use properties. Collateral values are determined based upon third-party appraisals. Permissible loan to value ratios at origination are governed by the Corporation’s policy and regulatory guidelines.

C&I loans consist of revolving, non-revolving and term loans extended to commercial borrowers for the purpose of providing working capital, equipment financing and financing for other business-related purposes. C&I loans are frequently collateralized by equipment, inventory, accounts receivable and/or general business assets. A portion of Washington Trust’s C&I loan portfolio is also collateralized by owner occupied real estate. C&I loans also include tax-exempt loans made to states and political subdivisions, as well as industrial development or revenue bonds issued through quasi-public corporations for the benefit of a private or non-profit entity where that entity rather than the governmental entity is obligated to pay the debt service. Washington Trust’s C&I loan portfolio includes loans to business sectors such as health care and social assistance, retail trade, transportation and warehousing, educational services, as well as other business sectors.

For the commercial portfolio, the Corporation typically obtains personal guarantees for payment from individuals holding material ownership interests in the borrowing entities.

Residential Real Estate Loans

Residential real estate loans held in the Corporation’s portfolio are made to borrowers who demonstrate the ability to make scheduled payments with full consideration to underwriting factors such as current and expected income, employment status, current assets, other financial resources, credit history and the value of the collateral. Collateral consists of mortgage liens on one-to-four family residential properties, including condominiums. Residential real estate loans also include loans to construct owner-occupied one-to-four family residential properties. Collateral values are determined based upon third-party appraisals. In general, loans must meet the underwriting and purchase standards imposed by Federal Home Loan Mortgage Corporation, Federal National Mortgage Association and other institutional investors as applicable.

Consumer Loans:

Home equity loans and credit lines are made to qualified individuals and are primarily secured by senior or junior mortgage liens on one-to-four family residential properties, including condominiums. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan to value ratios within established guidelines, as set forth in the Corporation’s policy.

Other consumer loans consist of loans to individuals that are secured by general aviation aircraft and other installment loans made to qualified individuals for various purposes. Borrower qualifications include favorable credit history combined with supportive income and collateral requirements within established guidelines, as set forth in the Corporation’s policy.

Note 6 -Derivative Financial Instruments

The Corporation’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Corporation’s known or expected cash receipts and its known or expected cash payments, principally to manage the Corporation’s interest rate risk. Additionally, the Corporation enters into interest rate derivatives to accommodate the business requirements of its customers. Derivatives are measured at fair value. Derivative assets are included in other assets and derivative liabilities are included in other liabilities in the Unaudited Consolidated Balance Sheets. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and resulting designation.

Interest Rate Risk Management Agreements

Interest rate risk management agreements, such as swaps, caps, floors, and collars, are used from time to time as part of the Corporation’s interest rate risk management strategy. Interest rate swaps are agreements in which the Corporation and another party agree to exchange interest payments (e.g., fixed-rate for variable-rate payments or variable-rate for fixed-rate payments) computed on a notional principal amount. Interest rate caps and floors represent options purchased by the

-25-

Corporation to manage the interest rate paid throughout the term of the option contract. An interest rate collar is a derivative instrument that represents simultaneously buying an interest rate cap and selling an interest rate floor. The credit risk associated with these derivative transactions is the risk of default by the counterparty. To minimize this risk, the Corporation enters into interest rate agreements only with highly rated counterparties that management believes to be creditworthy. The notional amounts of these agreements do not represent amounts exchanged by the parties and, thus, are not a measure of the potential loss exposure.

Cash Flow Hedging Instruments

As of September 30, 2026 and December 31, 2025, the Corporation had interest rate swaps, interest rate collars, and interest rate floors that were designated as cash flow hedges. The interest rate swaps and collars were executed to hedge the interest rate risk associated with short-term borrowings. See Note 9 for additional disclosure on borrowings. The interest rate floors were executed to hedge the interest rate risk associated with a pool of variable rate commercial loans.

The changes in fair value of these derivatives designated as cash flow hedges are recorded in other comprehensive income (loss) and subsequently reclassified to earnings when gains or losses are realized (i.e., in the same period during which the hedged transactions affect earnings.)

The Corporation previously had an interest rate swap contract that was designated as a cash flow hedge to hedge the interest rate risk associated with a pool of variable rate commercial loans. On March 31, 2023, the Corporation terminated this interest rate swap contract. On that date, the derivative liability was derecognized and the deferred loss that was included in the AOCL component of shareholders’ equity was updated to its termination date fair value of $26.5 million, or $20.1 million after tax. The deferred loss was amortized into earnings as a reduction of interest income on a straight-line basis over the life of the original interest rate swap term. The deferred loss was fully amortized as of May 1, 2026.

Fair Value Hedging Instruments

As of September 30, 2026 and December 31, 2025, the Corporation had interest rate swap contracts that were designated as fair value hedges. The fair value hedges were executed to hedge the interest rate risk associated with a closed-pool of fixed-rate residential real estate loans (the “hedged item”). The hedged item is measured at fair value through a basis adjustment recognized on the balance sheet. The changes in fair value of derivatives designated as fair value hedges, as well as the offsetting changes in fair value of the hedged item are recognized in earnings.

Loan Related Derivative Contracts

Interest Rate Derivative Contracts with Customers

The Corporation enters into interest rate swap and interest rate cap contracts to help commercial loan borrowers manage their interest rate risk. These interest rate swap contracts allow borrowers to convert variable-rate loan payments to fixed-rate loan payments, while interest rate cap contracts allow borrowers to limit their interest rate exposure in a rising rate environment. When the Corporation enters into an interest rate derivative contract with a commercial loan borrower, it simultaneously enters into a “mirror” interest rate contract with a third party. The Corporation’s credit policies with respect to interest rate contracts with commercial borrowers are similar to those used for loans. The Corporation retains the risk that is associated with the potential failure of counterparties and the risk inherent in originating loans. The interest rate contracts with counterparties are generally subject to bilateral collateralization terms. These derivatives are not designated as hedges and therefore, changes in fair value are recognized in earnings.

Risk Participation Agreements

The Corporation has entered into risk participation agreements with other banks in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. These derivatives are not designated as hedges and therefore, changes in fair value are recognized in earnings.

Under a risk participation-out agreement, a derivative asset, the Corporation participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Corporation assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower for a fee received from the other bank.

Mortgage Loan Commitments

Interest rate lock commitments are extended to borrowers and relate to the origination of mortgage loans held for sale. To mitigate the interest rate risk and pricing risk associated with rate locks and mortgage loans that are originated and intended for sale, the Corporation enters into forward sale commitments. Forward sale commitments are contracts for delayed delivery or net settlement of the underlying instrument, such as a mortgage loan, where the seller agrees to deliver on a specified future date, either a specified instrument at a specified price or yield or the net cash equivalent of an underlying instrument. Both interest rate lock commitments and forward sale commitments are derivative financial instruments, but do not meet criteria for hedge accounting and therefore, the changes in fair value of these commitments are recognized in earnings.

The following table presents the notional amounts and fair values of derivative instruments in the Unaudited Consolidated Balance Sheets:

(1)The fair value of derivative assets includes accrued interest receivable of $31 thousand and $35 thousand, respectively, at September 30, 2026 and December 31, 2025. The fair value of derivative liabilities includes accrued interest payable of $47 thousand and $23 thousand, respectively, at September 30, 2026 and December 31, 2025.

(2)Interest rate risk management contracts and loan related derivative contracts with counterparties are subject to master netting arrangements.

(3)Collateral contractually required to be pledged to derivative counterparties is in the form of cash. Washington Trust may need to post additional collateral in the future in proportion to potential increases in unrealized loss positions.

The following table presents the balance sheet location, carrying amount, and cumulative basis adjustment of the hedged item associated with fair value hedges:

(1)Represents the carrying amount of the hedged item associated with fair value hedges on a closed-pool of fixed-rate residential real estate loans that are expected to be outstanding for the designated hedged periods. The amortized cost balance of the closed-pool of residential real estate loans used in the fair value hedges was $577.3 million and $608.5 million, respectively, at September 30, 2026 and December 31, 2025.

Note 7 -Fair Value Measurements

The Corporation uses fair value measurements to record fair value adjustments on certain assets and liabilities and to determine fair value disclosures. Items recorded at fair value on a recurring basis include securities available for sale, mortgage loans that are originated and intended for sale to the secondary market, and derivatives. Additionally, from time to time, we may be required to record other assets at fair value on a nonrecurring basis, such as collateral dependent individually analyzed loans, loan servicing rights, and property acquired through foreclosure or repossession.

Fair value is a market-based measurement, not an entity-specific measurement. Fair value measurements are determined based on the assumptions the market participants would use in pricing the asset or liability. In addition, GAAP specifies a hierarchy of valuation techniques based on whether the types of valuation information, or “inputs”, are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Corporation’s market assumptions. These two types of inputs have created the following fair value hierarchy:

•Level 1 – Quoted prices foridentical assets or liabilities in active markets.

•Level 2 – Quoted prices forsimilar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

•Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers areunobservable in the markets and which reflect the Corporation’s market assumptions.

Fair Value Option Election

GAAP allows for the irrevocable option to elect fair value accounting for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. The Corporation has elected the fair value option for mortgage loans that are originated and intended for sale to the secondary market to better match changes in fair value of the loans with changes in the fair value of the forward sale commitment contracts used to economically hedge them.

The following table presents a summary of mortgage loans held for sale accounted for under the fair value option:

Changes in fair value of mortgage loans held for sale accounted for under the fair value option election are included in mortgage banking revenues in the Unaudited Consolidated Statements of Income. Changes in fair value amounted to decreases in mortgage banking revenues of $908 thousand and $973 thousand, respectively, for the three and nine months ended September 30, 2026, compared to a decrease in mortgage banking revenues of $175 thousand and an increase of $342 thousand, respectively, for the three and nine months ended September 30, 2025.

There were no mortgage loans held for sale 90 days or more past due as of September 30, 2026 and December 31, 2025.

Valuation Techniques for Items Recorded at Fair Value on a Recurring Basis

Available for Sale Debt Securities

Available for sale debt securities are recorded at fair value on a recurring basis. When available, the Corporation uses quoted market prices to determine the fair value of debt securities; such items are classified as Level 1. There were no Level 1 debt securities held at September 30, 2026 and December 31, 2025.

Level 2 debt securities are traded less frequently than exchange-traded instruments. The fair value of these securities is determined using matrix pricing with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category includes obligations of U.S. government-sponsored enterprises, including mortgage-backed securities, individual name issuer trust preferred debt securities, and corporate bonds.

-30-

Debt securities not actively traded whose fair value is determined through the use of cash flows utilizing inputs that are unobservable are classified as Level 3. There were no Level 3 debt securities held at September 30, 2026 and December 31, 2025.

Mortgage Loans Held for Sale, at Fair Value

The Corporation has elected the fair value option for mortgage loans that are originated and intended for sale to the secondary market. The fair value is estimated based on current market prices for similar loans in the secondary market and therefore are classified as Level 2 assets.

Derivatives

Interest rate derivative contracts are traded in over-the-counter markets where quoted market prices are not readily available. Fair value measurements are determined using independent valuation software, which utilizes the present value of future cash flows discounted using market observable inputs such as forward rate assumptions. The Corporation evaluates the credit risk of its counterparties, as well as that of the Corporation. Accordingly, factors such as the likelihood of default by the Corporation and its counterparties, its net exposures, and remaining contractual life are considered in determining if any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions that are subject to master netting agreements, as well as considering the amount of collateral securing the position, if any. The Corporation has determined that the majority of the inputs used to value its derivative positions fall within Level 2 of the fair value hierarchy. However, the credit valuation adjustments utilize Level 3 inputs. As of September 30, 2026 and December 31, 2025, the Corporation has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation. As a result, the Corporation has classified its derivative valuations in their entirety as Level 2.

Fair value measurements of forward loan commitments (interest rate lock commitments and forward sale commitments) are primarily based on current market prices for similar assets in the secondary market and therefore are classified as Level 2 assets. The fair value of interest rate lock commitments is also dependent on the ultimate closing of the loans. Pull-through rates are based on the Corporation’s historical data and reflect the Corporation’s best estimate of the likelihood that a commitment will result in a closed loan. Although the pull-through rates are Level 3 inputs, the Corporation has assessed the significance of the impact of pull-through rates on the overall valuation of its interest rate lock commitments and has determined that they are not significant to the overall valuation. As a result, the Corporation has classified its interest rate lock commitments as Level 2.

Items Recorded at Fair Value on a Recurring Basis

The following tables present the balances of assets and liabilities reported at fair value on a recurring basis:

Valuation Techniques for Items Recorded at Fair Value on a Nonrecurring Basis

Collateral Dependent Individually Analyzed Loans

Collateral dependent individually analyzed loans are valued based upon the lower of amortized cost or fair value. Fair value is determined based on the appraised value of the underlying collateral. Such collateral primarily consists of real estate and, to a lesser extent, other business assets. For collateral dependent loans that are expected to be repaid substantially through the sale of the collateral, management adjusts the fair value for estimated costs to sell. Management may also adjust appraised

-32- values to reflect estimated market value declines or apply other discounts to appraised values resulting from its knowledge of the collateral. Internal valuations may be utilized to determine the fair value of other business assets. Collateral dependent individually analyzed loans are categorized as Level 3.

Items Recorded at Fair Value on a Nonrecurring Basis

The following table presents the carrying value of assets held at September 30, 2026, which were written down to fair value during the nine months ended September 30, 2026:

Note 9 -Borrowings

Advances payable to the FHLB amounted to $376.0 million and $626.0 million, respectively, at September 30, 2026 and December 31, 2025. FHLB advances are collateralized by a blanket lien on collateral consisting of certain qualified investment securities and loans.

Available borrowing capacity with the FHLB amounted to $1.5 billion and $1.4 billion, respectively, as of September 30, 2026 and December 31, 2025. In addition, the Bank had access to a $40.0 million unused line of credit with the FHLB at both September 30, 2026 and December 31, 2025. The Bank also had standby letters of credit with the FHLB of $65.1 million and $66.0 million at September 30, 2026 and December 31, 2025 to collateralize institutional deposits.

See Note 6 for additional disclosure on derivatives designated as cash flow hedges to hedge the interest rate risk associated with short-term FHLB advances.

Note 10 -Shareholders' Equity

Stock Repurchase Program

The Board of Directors adopted the 2026 Repurchase Program, which authorizes the repurchase of up to 850,000 shares, or approximately 4.5%, of the Bancorp’s outstanding common stock. This authority may be exercised from time to time and in such amounts as market conditions warrant, and subject to regulatory considerations. The timing and actual number of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions, and other corporate liquidity requirements and priorities. Repurchases under the 2026 Repurchase Program will be conducted pursuant to a trading plan adopted by the Bancorp that is designed to qualify under Rule 10b5-1 under the Exchange Act. The 2026 Repurchase Program commenced on May 16, 2026 and expires on May 16, 2027 and may be modified, suspended, or discontinued at any time. There have beenno shares repurchased under the 2026 Repurchase Program.

The 2025 Repurchase Program expired on May 15, 2026. The Bancorp had repurchased a total of 267,658 shares, at an average price of $27.26 and a total cost of $7.4 million, under the 2025 Repurchase Program. No shares were repurchased in the three and nine months ended September 30, 2026. The total cost included $65 thousand of excise tax attributable to shares that were repurchased.

Regulatory Capital Requirements

Capital levels at September 30, 2026 exceeded the regulatory minimum levels to be considered “well capitalized.”

The following table presents the Corporation’s and the Bank’s actual capital amounts and ratios, as well as the corresponding minimum and well capitalized regulatory amounts and ratios that were in effect during the respective periods:

(1)Leverage ratio.

In addition to the minimum regulatory capital required for capital adequacy outlined in the table above, the Corporation and the Bank are required to maintain a minimum capital conservation buffer, in the form of common equity, of 2.50%, resulting in a requirement for the Corporation and the Bank to effectively maintain total capital, Tier 1 capital, and common equity Tier 1 capital ratios of 10.50%, 8.50%, and 7.00%, respectively. The Corporation and the Bank must maintain the capital conservation buffer to avoid restrictions on the ability to pay dividends and discretionary bonuses. The Corporation’s and the Bank’s capital levels exceeded the minimum regulatory capital requirements plus the capital conservation buffer at September 30, 2026 and December 31, 2025.

The Bancorp owns the common stock of two capital trusts, which have issued trust preferred securities. In accordance with GAAP, the capital trusts are treated as unconsolidated subsidiaries. At both September 30, 2026 and December 31, 2025, $22.0 million in trust preferred securities were included in the Tier 1 capital of the Corporation for regulatory capital reporting purposes pursuant to the capital adequacy guidelines of the Federal Reserve.

Note 11 -Revenue from Contracts with Customers

The following tables summarize total revenues as presented in the Unaudited Consolidated Statements of Income and the related amounts that are from contracts with customers within the scope of ASC 606. As shown below, a substantial portion of our revenues are specifically excluded from the scope of ASC 606.

(1)As reported in the Unaudited Consolidated Statements of Income.

(2)Revenue from contracts with customers in scope of ASC 606.

(1)As reported in the Unaudited Consolidated Statements of Income.

(2)Revenue from contracts with customers in scope of ASC 606.

(3)For the nine months ended September 30, 2025, included herein in accordance with sale-leaseback transaction provisions of ASC 842 and ASC 606.

-37-

The following table presents revenue from contracts with customers based on the timing of revenue recognition:

Receivables for revenue from contracts with customers primarily consist of amounts due for wealth management services performed for which the Corporation’s performance obligations have been fully satisfied. Receivables amounted to $5.9 million and $7.0 million at September 30, 2026 and December 31, 2025 and were included in other assets in the Unaudited Consolidated Balance Sheets.

Deferred revenues, which are considered contract liabilities under ASC 606, represent advance consideration received from customers for which the Corporation has a remaining performance obligation to fulfill. Contract liabilities are recognized as revenue over the life of the contract as the performance obligations are satisfied. The balances of contract liabilities were insignificant at both September 30, 2026 and December 31, 2025 and were included in other liabilities in the Unaudited Consolidated Balance Sheets.

For commissions and incentives that are in scope of ASC 606, such as those paid to employees in our wealth management services and banking segments in order to obtain customer contracts, contract cost assets are established. The contract cost assets are capitalized and amortized over the estimated useful life that the asset is expected to generate benefits. The carrying value of contract cost assets amounted to $2.1 million and $2.3 million, respectively, at September 30, 2026 and December 31, 2025 and were included in other assets in the Unaudited Consolidated Balance Sheets. The amortization of contract cost assets is recorded within salaries and employee benefits expense in the Unaudited Consolidated Statements of Income.

Note 12 -Business Segments

The Corporation manages its operations throughtwo reportable business segments, consisting of Banking and Wealth Management Services. The Corporation’s reportable business segments are determined by the Chairman and Chief Executive Officer, and the Senior Executive Vice President, Chief Financial Officer and Treasurer, the designated CODMs.

An allocation methodology is utilized to allocate income and expenses to the business segments. Direct activities are assigned to the appropriate business segment to which the activity relates. Indirect activities, such as corporate, technology and other support functions, are allocated to business segments primarily based upon full-time equivalent employee computations.

The Banking segment includes commercial, residential, and consumer lending activities; mortgage banking activities; deposit generation; treasury management services; other banking activities, including customer support and the operation of ATMs, telephone banking, internet banking, and mobile banking services; as well as investment portfolio and wholesale funding activities.

Wealth management services and operations are provided through the Bank and its registered investment adviser subsidiary. The Wealth Management Services segment provides investment management; holistic financial planning services; personal trust and estate services, including services as trustee, personal representative, and custodian; settlement of decedents’ estates; and institutional trust services, including custody and fiduciary services.

-38-

The CODMs evaluate the financial performance of each business segment, which is measured based upon the business segment’s net income. Components of net income for the business segments that are reviewed by the CODMs include net interest income, provision for credit losses, noninterest income, noninterest expense, and income tax expense. The CODMs, in conjunction with management committees and certain members of executive management, evaluate financial performance to make decisions related to the products and services that are offered, pricing, and the allocation of resources, for each business segment.

The following tables present the components of net income, as well as other supplemental information for Washington Trust’s reportable business segments:

(1)Included in net occupancy and equipment expenses in the table above.

Note 15 -Commitments and Contingencies

Financial Instruments with Off-Balance Sheet Risk

The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to manage the Corporation’s exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and standby letters of credit, as well as derivative financial instruments, such as mortgage loan commitments, loan related derivative contracts and interest rate risk management contracts. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the Unaudited Consolidated Balance Sheets. The contract or notional amounts of these instruments reflect the extent of involvement the Corporation has in particular classes of financial instruments. See Note 6 for additional disclosure pertaining to derivative financial instruments.

Financial Instruments Whose Contract Amounts Represent Credit Risk (Unfunded Commitments)

Commitments to Extend Credit

Commitments to extend credit are agreements to lend to a customer as long as there are no violations of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements. Each borrower’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained is based on management’s credit evaluation of the borrower.

Standby Letters of Credit

Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. These standby letters of credit are primarily issued to support the financing needs of the Bank’s commercial customers. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The collateral supporting those commitments is essentially the same as for other commitments. Most standby letters of credit extend for one year. At September 30, 2026 and December 31, 2025, there were no liabilities to beneficiaries resulting from standby letters of credit. Should the Corporation be required to make payments to the beneficiary, repayment from the customer to the Corporation is required.

The following table presents the contractual and notional amounts of financial instruments with off-balance sheet risk:

ACL on Unfunded Commitments

The ACL on unfunded commitments is management’s estimate of expected lifetime credit losses over the expected contractual term in which the Corporation is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Corporation.

The activity in the ACL on unfunded commitments for the three months ended September 30, 2026 is presented below:

Other Contingencies

Litigation

The Corporation is involved in various claims and legal proceedings arising out of the ordinary course of business. Management is of the opinion, based on its review with counsel of the development of such matters to date, that the ultimate disposition of such matters will not materially affect the consolidated balance sheets or statements of income of the Corporation.
