Nature of Operations	Nature of Operations The Company engages in the banking business through Shore United Bank, N.A. (the “Bank”), a national banking association with trust powers. The Company’s primary source of revenue is derived from interest earned on commercial, residential mortgage and other loans, and fees charged in connection with lending and other banking services located in Maryland, Delaware and Virginia. The Company engages in financial service offerings through Wye Financial Partners and offers corporate trustee services through Wye Trust, a division of the Bank. The Bank also conducts secondary market lending activities through a division of the Bank. Mid-Maryland Title Company, Inc. (the “Title Company”), engaged in title work related to real estate transactions. The Title Company ceased conducting real estate closings effective March 31, 2025.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and in the related disclosures. These estimates are based on information available as of the date of the consolidated financial statements. Actual amounts or results could differ from these estimates. In the opinion of management, all normal, recurring adjustments have been included for a fair presentation of this interim financial information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this ASU require an entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, which is greater than five percent of the amount computed by multiplying pretax income by the entity’s applicable statutory rate, on an annual basis. Additionally, the amendments in this ASU require an entity to disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions that are equal to or greater than five percent of total income taxes paid (net of refunds received). Lastly, the amendments in this ASU require an entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied on a prospective basis; however, retrospective application is permitted. The Company does not expect the adoption of ASU No. 2023-09 to have a material impact on its consolidated financial statements.
Fair Value Measurements	Accounting guidance under GAAP defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This accounting guidance also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities on a recurring basis and to determine fair value disclosures. Available for sale securities and equity securities with readily determinable fair values are recorded at fair value on a recurring basis, along with other mortgage-related items identified in the recurring fair value table below. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as collateral dependent loans, repossessed assets and OREO (foreclosed assets). These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Under fair value accounting guidance, assets and liabilities are grouped at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine their fair values. These hierarchy levels are: •Level 1 inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. •Level 2 inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. •Level 3 inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. Assets Measured at Fair Value on a Recurring Basis Available for Sale Securities Fair value measurement of AFS securities is based on quoted prices from an independent pricing service. The fair value measurements consider observable data that may include present value of future cash flows, prepayment assumptions, credit loss assumptions and other factors. The Company classifies its investments in U.S. Treasury securities, if any, as Level 1 in the fair value hierarchy, and it classifies its investments in U.S. government agency securities and mortgage-backed securities issued or guaranteed by U.S. government-sponsored entities as Level 2. Equity Securities Fair value measurement for equity securities is based on quoted market prices retrieved by the Company via online resources. Although these securities have readily available fair market values, the Company determined that they should be classified as level 2 investments in the fair value hierarchy due to not being considered traded in a highly active market. Loans Held for Sale Loans held for sale are carried at fair value, which is determined based on Mark to Trade for allocated/committed loans or Mark to Market analysis for unallocated/uncommitted loans based on third-party pricing models (Level 2). IRLCs The Company utilizes a third-party specialist model to estimate the fair value of IRLCs, which are valued based upon mortgage securities (TBA) prices less estimated costs to process and settle the loan. Fair value is adjusted for the estimated probability of the loan closing with the borrower (Level 3).
Revenue Recognition	Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees and merchant income. Noninterest revenue streams in-scope of Topic 606 are discussed below. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. Service Charges on Deposit Accounts Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account-related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or at the end of the month through a direct charge to customers’ accounts. Trust and Investment Fee Income Trust and investment fee income primarily comprise fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time, and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered. Other Noninterest Income Other noninterest income consists of fees, exchange, other service charges, safety deposit box rental fees, and other miscellaneous revenue streams. Fees and other service charges primarily comprise debit and credit card income, automated teller machine (“ATM”) fees, merchant services income, and other service charges. Debit and credit card income primarily comprises interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as Mastercard and Visa. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment.

•Level 3 inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

Assets Measured at Fair Value on a Recurring Basis

Available for Sale Securities

Fair value measurement of AFS securities is based on quoted prices from an independent pricing service. The fair value measurements consider observable data that may include present value of future cash flows, prepayment assumptions, credit loss assumptions and other factors. The Company classifies its investments in U.S. Treasury securities, if any, as Level 1 in the fair value hierarchy, and it classifies its investments in U.S. government agency securities and mortgage-backed securities issued or guaranteed by U.S. government-sponsored entities as Level 2.

Equity Securities

Fair value measurement for equity securities is based on quoted market prices retrieved by the Company via online resources. Although these securities have readily available fair market values, the Company determined that they should be classified as level 2 investments in the fair value hierarchy due to not being considered traded in a highly active market.

Loans Held for Sale

Loans held for sale are carried at fair value, which is determined based on Mark to Trade for allocated/committed loans or Mark to Market analysis for unallocated/uncommitted loans based on third-party pricing models (Level 2).

IRLCs

The Company utilizes a third-party specialist model to estimate the fair value of IRLCs, which are valued based upon mortgage securities (TBA) prices less estimated costs to process and settle the loan. Fair value is adjusted for the estimated probability of the loan closing with the borrower (Level 3).

Revenue Recognition

Topic 606 is applicable to noninterest revenue streams such as trust and asset management income, deposit related fees, interchange fees and merchant income. Noninterest revenue streams in-scope of Topic 606 are discussed below. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities.

Service Charges on Deposit Accounts

Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided.

Check orders and other deposit account-related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or at the end of the month through a direct charge to customers’ accounts.

Trust and Investment Fee Income

Trust and investment fee income primarily comprise fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time, and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customers’ accounts. The Company does not earn performance-based incentives.

Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered.

Other Noninterest Income

Other noninterest income consists of fees, exchange, other service charges, safety deposit box rental fees, and other miscellaneous revenue streams. Fees and other service charges primarily comprise debit and credit card income, automated teller machine (“ATM”) fees, merchant services income, and other service charges.

ATM fees are primarily

generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees. Other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion.
