Basis of Presentation	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 the 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, 2023. 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.

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: (Dollars in thousands) Less than 12 Months 12 Months or Longer Total September 30, 2024 # Fair Unrealized # Fair Unrealized # Fair Unrealized Obligations of U.S. government-sponsored enterprises 1 $20,000 ($1) 18 $191,487 ($18,462) 19 $211,487 ($18,463) Mortgage-backed securities issued by U.S. government agencies and U.S. government-sponsored enterprises — — — 150 659,027 (106,614) 150 659,027 (106,614) Individual name issuer trust preferred debt securities — — — 3 9,193 (217) 3 9,193 (217) Corporate bonds — — — 4 12,558 (635) 4 12,558 (635) Total 1 $20,000 ($1) 175 $872,265 ($125,928) 176 $892,265 ($125,929) (Dollars in thousands) Less than 12 Months 12 Months or Longer Total December 31, 2023 # Fair Unrealized # Fair Unrealized # Fair Unrealized Obligations of U.S. government-sponsored enterprises 1 $19,824 ($176) 20 $195,903 ($24,547) 21 $215,727 ($24,723) Mortgage-backed securities issued by U.S. government agencies and U.S. government-sponsored enterprises 8 43,887 (262) 154 698,115 (125,625) 162 742,002 (125,887) Individual name issuer trust preferred debt securities — — — 3 8,793 (607) 3 8,793 (607) Corporate bonds — — — 4 11,889 (1,293) 4 11,889 (1,293) Total 9 $63,711 ($438) 181 $914,700 ($152,072) 190 $978,411 ($152,510) There were no debt securities on nonaccrual status at September 30, 2024 and 2023 and, therefore there was no accrued interest related to debt securities reversed against interest income for the three and nine months ended September 30, 2024 and 2023. As of September 30, 2024, the Corporation does not intend to sell the debt securities in an unrealized loss position and has determined that it is more-likely-than-not that the Corporation will not be required to sell each security before the recovery of its amortized cost basis. In addition, management does not believe that any of the securities are impaired due to reasons of credit quality. 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. Therefore, no ACL was recorded at both September 30, 2024 and December 31, 2023. 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, 2024. 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, 2024 included three trust preferred securities issued by three 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, 2024, there was one individual name issuer trust preferred debt security with an amortized cost of $2.0 million and unrealized losses of $140 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between September 30, 2024 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, 2024 included four corporate bond holdings issued by three 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, 2024, there was one corporate bond debt security with an amortized cost of $2.0 million and unrealized losses of $25 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between September 30, 2024 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.

As of September 30, 2024 and December 31, 2023, loans amounting to $3.3 billion and $3.4 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. 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: (Dollars in thousands) Days Past Due September 30, 2024 Current 30-59 60-89 90 or More Total Past Due Total Loans Commercial: Commercial real estate $2,091,615 $— $10,476 $— $10,476 $2,102,091 Commercial & industrial 566,276 3 — — 3 566,279 Total commercial 2,657,891 3 10,476 — 10,479 2,668,370 Residential Real Estate: Residential real estate 2,522,450 912 3,856 2,179 6,947 2,529,397 Consumer: Home equity 296,579 1,520 533 747 2,800 299,379 Other 17,649 75 — — 75 17,724 Total consumer 314,228 1,595 533 747 2,875 317,103 Total loans $5,494,569 $2,510 $14,865 $2,926 $20,301 $5,514,870 (Dollars in thousands) Days Past Due December 31, 2023 Current 30-59 60-89 90 or More Total Past Due Total Loans Commercial: Commercial real estate $2,106,359 $— $— $— $— $2,106,359 Commercial & industrial 605,062 10 — — 10 605,072 Total commercial 2,711,421 10 — — 10 2,711,431 Residential Real Estate: Residential real estate 2,596,362 4,369 1,738 2,009 8,116 2,604,478 Consumer: Home equity 309,398 2,349 112 735 3,196 312,594 Other 19,180 20 3 — 23 19,203 Total consumer 328,578 2,369 115 735 3,219 331,797 Total loans $5,636,361 $6,748 $1,853 $2,744 $11,345 $5,647,706 Included in past due loans as of September 30, 2024 and December 31, 2023, were nonaccrual loans of $18.1 million and $6.9 million, respectively. In addition, all loans 90 days or more past due at September 30, 2024 and December 31, 2023 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. The following table is a summary of nonaccrual loans, segregated by class of loans: (Dollars in thousands) September 30, 2024 December 31, 2023 Nonaccrual Loans Nonaccrual Loans With an ACL Without an ACL Total With an ACL Without an ACL Total Commercial: Commercial real estate $10,475 $7,784 $18,259 $10,997 $21,830 $32,827 Commercial & industrial — 616 616 — 682 682 Total commercial 10,475 8,400 18,875 10,997 22,512 33,509 Residential Real Estate: Residential real estate 9,489 1,028 10,517 8,495 1,131 9,626 Consumer: Home equity 1,750 — 1,750 1,483 — 1,483 Other — — — — — — Total consumer 1,750 — 1,750 1,483 — 1,483 Total nonaccrual loans $21,714 $9,428 $31,142 $20,975 $23,643 $44,618 Accruing loans 90 days or more past due $— $— Nonaccrual loans of $13.0 million and $37.7 million, respectively, at September 30, 2024 and December 31, 2023 were current as to the payment of principal and interest. As of September 30, 2024 and December 31, 2023, nonaccrual loans secured by one- to four-family residential property amounting to $2.4 million and $960 thousand, respectively, were in process of foreclosure. There were no significant commitments to lend additional funds to borrowers whose loans were on nonaccrual status at September 30, 2024. The following table presents interest income recognized on nonaccrual loans: (Dollars in thousands) Three Months Nine Months Periods ended September 30, 2024 2023 2024 2023 Commercial: Commercial real estate $— $474 $— $1,344 Commercial & industrial — 9 — 35 Total commercial — 483 — 1,379 Residential Real Estate: Residential real estate 139 82 332 341 Consumer: Home equity 36 22 106 59 Other — 1 — 3 Total consumer 36 23 106 62 Total $175 $588 $438 $1,782 Troubled Loan Modifications In the course of resolving problem loans, the Corporation may choose to modify the contractual terms of certain loans. 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. The decision to modify a loan, versus aggressively enforcing the collection of the loan, may benefit the Corporation by increasing the ultimate probability of collection. 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. Nonaccrual loans that become TLMs generally remain on nonaccrual status for six months, subsequent to being modified, before management considers their return 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. In addition, if a TLM is subsequently modified and the borrower is no longer experiencing financial difficulty, it would be declassified from TLM status. During the three months ended September 30, 2024, there were no loans modified as a TLM. The following table presents the carrying value of TLMs made during the nine months ended September 30, 2024, segregated by class of loans and type of concession granted: (Dollars in thousands) Maturity Extension Other-than-Insignificant Payment Delay Total % of Loan Class (1) Commercial: Commercial real estate $— $— $— — % Commercial & industrial 616 — 616 — Total commercial 616 — 616 — Residential Real Estate: Residential real estate — 265 265 — Total $616 $265 $881 — % (1) Percentage of TLMs to the total loans outstanding within the respective loan class.

There were no significant commitments to lend additional funds to borrowers experiencing financial difficulty whose loans were TLMs at September 30, 2024. Individually Analyzed Loans Individually analyzed loans are individually assessed for credit impairment and include nonaccrual commercial loans, TLMs, as well as certain other loans based on the underlying risk characteristics and the discretion of management to individually analyze such loans. As of September 30, 2024 and December 31, 2023, individually analyzed loans amounted to $19.9 million and $34.6 million, respectively, all of which were considered collateral dependent. 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.

(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. 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 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	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. All derivatives are recognized as either assets or liabilities on the balance sheet and 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 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 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, 2024 and December 31, 2023, the Corporation had interest rate swap contracts that were designated as cash flow hedges. In addition, at September 30, 2024, the Corporation had an interest rate collar that was designated as a cash flow hedge. These cash flow hedges were executed to hedge the interest rate risk associated with short-term borrowings. See Note 9 for additional disclosure on borrowings. On March 31, 2023, the Corporation terminated 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 the termination date, the derivative liability was derecognized. The loss on this interest rate swap 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. This loss is being amortized into earnings as a reduction of interest income on a straight-line basis over the remaining life of the original interest rate swap term, or through May 1, 2026. At September 30, 2024, the remaining unamortized balance of the loss included in the AOCL component of shareholders’ equity was $13.6 million, or $10.1 million after tax. The changes in fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income (loss) and subsequently reclassified to earnings when gains or losses are realized. Fair Value Hedging Instruments As of September 30, 2024, 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”). See Note 4 for additional disclosure on residential real estate loans. 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. For interest rate swaps, the third party exchanges the client’s fixed-rate loan payments for variable-rate loan payments. 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 held 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 residential real estate 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.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	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 held for sale, 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. 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 for identical assets or liabilities in active markets. • Level 2 – Quoted prices for similar 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 are unobservable 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 held for sale 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: (Dollars in thousands) September 30, December 31, Aggregate fair value $20,864 $20,077 Aggregate principal balance 20,389 19,480 Difference between fair value and principal balance $475 $597 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 $31 thousand and $122 thousand, respectively, for the three and nine months ended September 30, 2024. This compared to decreases in mortgage banking revenues of $39 thousand and $21 thousand, respectively, for the three and nine months ended September 30, 2023. There were no mortgage loans held for sale 90 days or more past due as of September 30, 2024 and December 31, 2023. Valuation Techniques 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, 2024 and December 31, 2023. 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. 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, 2024 and December 31, 2023. Mortgage Loans Held for Sale The Corporation has elected the fair value option for mortgage loans held for sale. 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. 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 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. Loan Servicing Rights Loans sold with the retention of servicing result in the recognition of loan servicing rights. Loan servicing rights are included in other assets in the Unaudited Consolidated Balance Sheets and are amortized as an offset to mortgage banking revenues over the estimated period of servicing. Loan servicing rights are evaluated quarterly for impairment based on their fair value. Impairment exists if the carrying value exceeds the estimated fair value. Impairment is measured on an aggregated basis by stratifying the loan servicing rights based on homogeneous characteristics such as note rate and loan type. The fair value is estimated using an independent valuation model that estimates the present value of expected cash flows, incorporating assumptions for discount rates and prepayment rates. Any impairment is recognized through a valuation allowance and as a reduction to mortgage banking revenues. Loan servicing rights are categorized as Level 3. 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, 2024 and December 31, 2023, 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 for mortgage loans 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.

Equity [Abstract]
Shareholders' Equity	Shareholders' Equity Stock Repurchase Program The 2024 Repurchase Program authorizes the repurchase of up to 850,000 shares, or approximately 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 numbers 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. The 2024 Repurchase Program commenced on January 1, 2024 and expires on December 31, 2024, and may be modified, suspended, or discontinued at any time. As of September 30, 2024, no shares have been repurchased under the 2024 Repurchase Program. Regulatory Capital Requirements Capital levels at September 30, 2024 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: (Dollars in thousands) Actual For Capital Adequacy Purposes To Be “Well Capitalized” Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio September 30, 2024 Total Capital (to Risk-Weighted Assets): Corporation $618,974 12.21 % $405,397 8.00 % N/A N/A Bank 612,980 12.10 405,250 8.00 $506,562 10.00 % Tier 1 Capital (to Risk-Weighted Assets): Corporation 577,073 11.39 304,048 6.00 N/A N/A Bank 571,079 11.27 303,937 6.00 405,250 8.00 Common Equity Tier 1 Capital (to Risk-Weighted Assets): Corporation 555,077 10.95 228,036 4.50 N/A N/A Bank 571,079 11.27 227,953 4.50 329,265 6.50 Tier 1 Capital (to Average Assets): (1) Corporation 577,073 7.85 293,972 4.00 N/A N/A Bank 571,079 7.77 293,870 4.00 367,338 5.00 December 31, 2023 Total Capital (to Risk-Weighted Assets): Corporation 611,220 11.58 422,259 8.00 N/A N/A Bank 605,289 11.47 422,131 8.00 527,663 10.00 Tier 1 Capital (to Risk-Weighted Assets): Corporation 572,960 10.86 316,694 6.00 N/A N/A Bank 567,029 10.75 316,598 6.00 422,131 8.00 Common Equity Tier 1 Capital (to Risk-Weighted Assets): Corporation 550,964 10.44 237,521 4.50 N/A N/A Bank 567,029 10.75 237,449 4.50 342,981 6.50 Tier 1 Capital (to Average Assets): (1) Corporation 572,960 7.80 293,837 4.00 N/A N/A Bank 567,029 7.72 293,742 4.00 367,177 5.00 (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, 2024 and December 31, 2023. 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, 2024 and December 31, 2023, $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. In accordance with regulatory capital rules, the Corporation elected the option to delay the estimated impact of ASC 326 on its regulatory capital over a two-year deferral and subsequent three-year transition period ending December 31, 2024. As a result, capital ratios exclude the full impact of the increased ACL on loans and unfunded loan commitments attributed to the adoption of ASC 326, adjusted for an approximation of the after-tax provision for credit losses attributable to ASC 326 relative to the incurred loss methodology during the two-year deferral period. The cumulative difference at the end of the deferral period is being phased-in to regulatory capital over the three-year transition period, which began January 1, 2022.

Receivables amounted to $5.9 million and $5.5 million, respectively, at September 30, 2024 and December 31, 2023 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, 2024 and December 31, 2023 and were included in other liabilities in the Unaudited Consolidated Balance Sheets. For commission and incentive costs that are in scope of ASC 606, such as those paid to employees in our wealth management services and commercial 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 $2.0 million at both September 30, 2024 and December 31, 2023 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.

Retirement Benefits [Abstract]
Defined Benefit Pension Plans	Defined Benefit Pension Plans Washington Trust maintains a qualified pension plan for the benefit of certain eligible employees who were hired prior to October 1, 2007. Washington Trust also has non-qualified retirement plans to provide supplemental retirement benefits to certain employees, as defined in the plans. These defined benefit pension plans were previously amended to freeze benefit accruals after a 10-year transition period, which ended in December 2023. In the fourth quarter of 2023, the Corporation’s Board of Directors approved a resolution to terminate the qualified pension plan, and participants were notified of the termination. Work on the qualified pension plan termination process continues to progress and the qualified pension plan’s assets are expected to be distributed in 2025, pending completion of applicable regulatory approvals. The qualified pension plan liability is expected to be settled in 2025 through a combination of lump sum payments to participants and purchase of a group annuity contract from a highly-rated insurance company. Upon settlement in 2025, the Corporation expects to recognize a pre-tax pension settlement charge that will include a non-cash charge for the recognition of all pre-tax actuarial losses accumulated in AOCL at that time. The actual amount of the settlement charge will depend on various factors, including interest rates, plan asset returns, the lump sum election rate and annuity pricing.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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, 2024 and December 31, 2023, 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: (Dollars in thousands) September 30, December 31, Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $1,068,899 $1,185,196 Standby letters of credit 12,216 9,323 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.

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.
