Basis of Presentation [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation ​ The consolidated financial statements include the accounts of Shore Bancshares, Inc. and its subsidiary with all significant intercompany transactions eliminated. The consolidated financial statements conform to accounting principles generally accepted in the United States of America (“GAAP”) and to prevailing practices within the banking industry. The accompanying interim financial statements are unaudited; however, in the opinion of management all adjustments necessary to present fairly the consolidated financial position at March 31, 2021, the consolidated results of income and comprehensive income for the three months ended March 31, 2021 and 2020, changes in stockholders’ equity for the three months ended March 31, 2021 and 2020 and cash flows for the three months ended March 31, 2021 and 2020, have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2020 were derived from the 2020 audited financial statements. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for any other interim period or for the full year. This Quarterly Report on Form 10-Q should be read in conjunction with the Annual Report of Shore Bancshares, Inc. on Form 10-K for the year ended December 31, 2020. For purposes of comparability, certain immaterial reclassifications have been made to amounts previously reported to conform with the current period presentation. When used in these notes, the term “the Company” refers to Shore Bancshares, Inc. and, unless the context requires otherwise, its consolidated subsidiary, Shore United Bank (the “Bank”). ​ Risks and Uncertainties ​ Since the novel coronavirus ("COVID-19") was declared a pandemic in March 2020, COVID-19 has significantly affected our communities, customers, and operations. COVID-19 continues to have a significant impact in 2021, however, the extent of its effects are dependent upon multiple factors, such as the extent of distribution and efficacy of vaccines, COVID-19 variants, pandemic-related restrictions, and government response, among others. As a result, the ultimate effects of COVID-19 over the longer term cannot be reasonably estimated at this time. Risks and uncertainties arising from the pandemic remain, primarily concerning the ability of customers to fulfill their financial obligations to the Company as well as potential operational disruptions and the ability of the Company to generate demand for its products and services. Accordingly, estimates used in the preparation of our financial statements may be subject to significant adjustments in future periods. ​ Recent Accounting Standards and Other Authoritative Guidance ASU No. 2016-13 – In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. At the FASB’s October 16, 2019 meeting, the Board affirmed its decision to amend the effective date of this ASU for many companies. Public business entities that are SEC filers, excluding those meeting the smaller reporting company definition, will retain the initial required implementation date of fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. All other entities will be required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022 . The team is currently running a parallel simulation to its current incurred loss impairment model. The Company is continuing to evaluate the extent of the potential impact of this standard and continues to keep current on evolving interpretations and industry practices via webcasts, publications, conferences, and peer bank meetings. ​ Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin (SAB) 119. SAB 119 updated portions of SEC interpretative guidance to align with FASB ASC 326, “Financial Instruments – Credit Losses.” It covers topics including (1) measuring current expected credit losses; (2) development, governance, and documentation of a systematic methodology; (3) documenting the results of a systematic methodology; and (4) validating a systematic methodology. ​ ASU No. 2020-04 – In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. At present, the Bank has limited exposure to LIBOR based pricing. LIBOR based loans only comprise 28 loans or 7.9% of the loan portfolio. The Bank is confident it can successfully negotiate a migration to the Secured Overnight Financing Rate (“SOFR”) between now and the implementation date. The Bank will notify customers within 120 days prior to migration to SOFR. The Bank acknowledges the replacement rate will be more volatile based on different countries migrating to different indexes and limited liquidity to support the rate. The Bank further acknowledges the volatility will be greatly influenced by the support provided by the Federal Reserve. ​ In October 2020, the FASB issued ASU 2020-08, “Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable fees and Other Costs.” This ASU clarifies that an entity should reevaluate whether a callable debt security is within the scope of ASC paragraph 310-20-35-33 for each reporting period. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is not permitted. All entities should apply ASU No. 2020-08 on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company does not expect the adoption of ASU 2020-08 to have a material impact on its consolidated financial statements. ​ Recently Adopted Accounting Developments ​ ASU No. 2019-12 – In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes.” The ASU is expected to reduce cost and complexity related to the accounting for income taxes by removing specific exceptions to general principles in Topic 740 (eliminating the need for an organization to analyze whether certain exceptions apply in a given period) and improving financial statement preparers’ application of certain income tax-related guidance. This ASU is part of the FASB’s simplification initiative to make narrow-scope simplifications and improvements to accounting standards through a series of short-term projects. The amendments were effective in the first quarter of 2021 for the Company and there was no material impact on the Company’s Consolidated Financial Statements. ​ ASU No. 2020-01 – In January 2020, the FASB issued ASU 2020-01, “Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321, Topic 323, and Topic 815.” The ASU is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. ASU 2016-01 made targeted improvements to accounting for financial instruments, including providing an entity the ability to measure certain equity securities without a readily determinable fair value at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Among other topics, the amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting. The amendments were effective in the first quarter of 2021 for the Company and there was no material impact on the Company’s Consolidated Financial Statements.

The unrealized losses on debt securities that exist are the result of market changes in interest rates since original purchase. Because the Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized cost basis, which may be at maturity for debt securities, the Company considers the unrealized losses to be temporary. There were eighteen available-for-sale securities and nineteen held-to-maturity securities in an unrealized loss position at March 31, 2021. The following table provides information on the amortized cost and estimated fair values of investment securities by maturity date at March 31, 2021. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Available for sale ​ Held to maturity ​ Amortized ​ ​ Amortized ​ ​ (Dollars in thousands) ​ Cost ​ Fair Value ​ Cost ​ Fair Value Due in one year or less ​ $ — ​ $ — ​ $ — ​ $ — Due after one year through five years ​ 1,174 ​ 1,214 ​ 7,919 ​ 7,968 Due after five years through ten years ​ 57,863 ​ 59,015 ​ 37,492 ​ 37,403 Due after ten years ​ 64,038 ​ 63,874 ​ 80,518 ​ 79,705 Total ​ $ 123,075 ​ $ 124,103 ​ $ 125,929 ​ $ 125,076 ​ The maturity dates for debt securities are determined using contractual maturity dates.

Loans and Allowance for Credit Losses [Abstract]
Loans and Allowance for Credit Losses	Note 4 – Loans and Allowance for Credit Losses The Company makes residential mortgage, commercial and consumer loans to customers primarily in Talbot County, Queen Anne’s County, Kent County, Caroline County, Dorchester County, Worcester County, Baltimore County and Howard County in Maryland, Kent County, Delaware and Accomack County, Virginia. The following table provides information about the principal classes of the loan portfolio at March 31, 2021 and December 31, 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) March 31, 2021 December 31, 2020 Construction ​ $ 115,971 ​ $ 106,760 ​ Residential real estate ​ 449,651 ​ 443,542 ​ Commercial real estate ​ 641,155 ​ 661,232 ​ Commercial ​ 218,923 ​ 211,256 ​ Consumer ​ 35,822 ​ 31,466 ​ Total loans ​ 1,461,522 ​ 1,454,256 ​ Allowance for credit losses ​ (14,313) ​ (13,888) ​ Total loans, net ​ $ 1,447,209 ​ $ 1,440,368 ​ ​ Loans are stated at their principal amount outstanding net of any purchase premiums/discounts, deferred fees and costs. Loans included deferred fees, net of costs, of $751 thousand and discounts on acquired loans of $677 thousand at March 31, 2021. Loans included deferred costs, net of deferred fees, of $622 thousand and discounts on acquired loans of $754 thousand at December 31, 2020. At March 31, 2021 and December 31, 2020, included in total loans were $44.6 million and $52.3 million in loans, respectively, acquired as part of the NWBI branch acquisition in 2017. Interest income on loans is accrued at the contractual rate based on the principal amount outstanding. Fees charged and costs capitalized for originating loans are being amortized substantially on the interest method over the term of the loan. A loan is placed on nonaccrual (i.e., interest income is no longer accrued) when it is specifically determined to be impaired or when principal or interest is delinquent for 90 days or more, unless the loan is well secured and in the process of collection. Any unpaid interest previously accrued on those loans is reversed from income. Interest payments received on nonaccrual loans are applied as a reduction of the loan principal balance unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. A loan is considered impaired if it is probable that the Company will not collect all principal and interest payments according to the loan’s contractual terms when due. An impaired loan may show deficiencies in the borrower’s overall financial condition, payment history, support available from financial guarantors and/or the fair market value of collateral. The impairment of a loan is measured at the present value of expected future cash flows using the loan’s effective interest rate, or at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. Generally, the Company measures impairment on such loans by reference to the fair value of the collateral. Once the amount of impairment has been determined, the uncollectible portion is charged off. Loan payments received on nonaccrual impaired loans are generally applied to the outstanding principal balance. In certain circumstances, income may be recognized on a cash basis. Generally, interest income is not recognized on impaired loans unless the likelihood of further loss is remote. The allowance for credit losses may include specific reserves related to impaired loans. Specific reserves remain until charge offs are made. Impaired loans do not include groups of smaller balance homogenous loans such as residential mortgage and consumer installment loans that are evaluated collectively for impairment. Reserves for probable credit losses related to these loans are based on historical loss ratios and are included in the formula portion of the allowance for credit losses. A loan is considered a TDR if a borrower is experiencing financial difficulties and a creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, restructuring amortization schedules and other actions intended to minimize potential losses. Loans are identified to be restructured when signs of impairment arise such as borrower interest rate reduction request, slowness to pay, or when an inability to repay becomes evident. The terms being offered are evaluated to determine if they are more liberal than those that would be indicated by policy or industry standards for similar, untroubled credits. In those situations where the terms or the interest rates are considered to be more favorable than industry standards or the Bank’s current underwriting guidelines the loan is classified as a TDR. All loans designated as TDRs are considered impaired loans and may be on either accrual or nonaccrual status. In instances where the loan has been placed on nonaccrual status, six consecutive months of timely payments are required prior to returning the loan to accrual status. All loans classified as TDRs which are restructured and accrue interest under revised terms require a full and comprehensive review of the borrower’s financial condition, capacity for repayment, realistic assessment of collateral values, and the assessment of risk entered into any workout agreement. Current financial information on the borrower, guarantor, and underlying collateral is analyzed to determine if it supports the ultimate collection of principal and interest. For commercial loans, the cash flows are analyzed, both for the underlying project and globally. For consumer loans, updated salary, credit history and cash flow information is obtained. Current market conditions are also considered. Following a full analysis, the determination of the appropriate loan structure is made. In 2020, the Company began its participation in the Paycheck Protection Program (PPP). The PPP commenced subsequent to the passage of the Coronavirus Aid, Relief and Economic Security (“CARES”) Act in March 2020, and was later expanded by the Paycheck Protection Program and Health Care Enhancement Act of April 2020. The PPP was designed to provide U.S. small businesses with cash-flow assistance during the COVID-19 pandemic through loans that are fully guaranteed by the Small Business Administration (SBA) which may be forgiven upon satisfaction of certain criteria. As of March 31, 2021, the Company held PPP loans with a total outstanding balance of $129.1 million, which is included in the commercial loan segment in the table above. As compensation for originating the loans, the Company received lender processing fees from the SBA, which were deferred, along with the related loan origination costs. These net fees are being accreted to interest income over the remaining contractual lives of the loans. Upon forgiveness of a PPP loan and repayment by the SBA, which may be prior to the loan’s maturity, the remainder of any unrecognized net fees are recognized as interest income. The Company has continued to participate in the newest round of the PPP during the first quarter of 2021. In the normal course of banking business, risks related to specific loan categories are as follows: Construction loans – Construction loans are offered primarily to builders and individuals to finance the construction of single-family dwellings. In addition, the Bank periodically finances the construction of commercial projects. Credit risk factors include the borrower’s ability to successfully complete the construction on time and within budget, changing market conditions which could affect the value and marketability of projects, changes in the borrower’s ability or willingness to repay the loan and potentially rising interest rates which can impact both the borrower’s ability to repay and the collateral value. ​ Residential real estate – Residential real estate loans are typically made to consumers and are secured by residential real estate. Credit risk arises from the borrower’s continuing financial stability, which can be adversely impacted by job loss, divorce, illness, or personal bankruptcy, among other factors. Also impacting credit risk would be a shortfall in the value of the residential real estate in relation to the outstanding loan balance in the event of a default or subsequent liquidation of the real estate collateral. Commercial real estate – Commercial real estate loans consist of both loans secured by owner occupied properties and non-owner occupied properties where an established banking relationship exists and involves investment properties for warehouse, retail, and office space with a history of occupancy and cash flow. These loans are subject to adverse changes in the local economy and commercial real estate markets. Credit risk associated with owner occupied properties arises from the borrower’s financial stability and the ability of the borrower and the business to repay the loan. Non-owner occupied properties carry the risk of a tenant’s deteriorating credit strength, lease expirations in soft markets and sustained vacancies which can adversely impact cash flow. Commercial – Commercial loans are secured or unsecured loans for business purposes. Loans are typically secured by accounts receivable, inventory, equipment and/or other assets of the business. Credit risk arises from the successful operation of the business which may be affected by competition, rising interest rates, regulatory changes and adverse conditions in the local and regional economy. Consumer – Consumer loans include home equity loans and lines, installment loans and personal lines of credit. Credit risk is similar to residential real estate loans above as it is subject to the borrower’s continuing financial stability and the value of the collateral securing the loan. The following tables include impairment information relating to loans and the allowance for credit losses as of March 31, 2021 and December 31, 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential Commercial ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ Construction ​ real estate ​ real estate ​ Commercial ​ Consumer ​ Total March 31, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans individually evaluated for impairment ​ $ 329 ​ $ 5,281 ​ $ 6,638 ​ $ 248 ​ $ 28 ​ $ 12,524 Loans collectively evaluated for impairment ​ 115,642 ​ 444,370 ​ 634,517 ​ 218,675 ​ 35,794 ​ 1,448,998 Total loans ​ $ 115,971 ​ $ 449,651 ​ $ 641,155 ​ $ 218,923 ​ $ 35,822 ​ $ 1,461,522 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Allowance for credit losses allocated to: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans individually evaluated for impairment ​ $ — ​ $ 95 ​ $ — ​ $ — ​ $ — ​ $ 95 Loans collectively evaluated for impairment ​ 2,796 ​ 3,604 ​ 5,097 ​ 2,000 ​ 721 ​ 14,218 Total allowance ​ $ 2,796 ​ $ 3,699 ​ $ 5,097 ​ $ 2,000 ​ $ 721 ​ $ 14,313 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential Commercial ​ ​ ​ ​ ​ ​ (Dollars in thousands) ​ Construction ​ real estate ​ real estate ​ Commercial ​ Consumer ​ Total December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans individually evaluated for impairment ​ $ 331 ​ $ 5,722 ​ $ 6,917 ​ $ 258 ​ $ 28 ​ $ 13,256 Loans collectively evaluated for impairment ​ 106,429 ​ 437,820 ​ 654,315 ​ 210,998 ​ 31,438 ​ 1,441,000 Total loans ​ $ 106,760 ​ $ 443,542 ​ $ 661,232 ​ $ 211,256 ​ $ 31,466 ​ $ 1,454,256 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Allowance for credit losses allocated to: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans individually evaluated for impairment ​ $ — ​ $ 135 ​ $ 78 ​ $ — ​ $ — ​ $ 213 Loans collectively evaluated for impairment ​ 2,022 ​ 3,564 ​ 5,348 ​ 2,089 ​ 652 ​ 13,675 Total allowance ​ $ 2,022 ​ $ 3,699 ​ $ 5,426 ​ $ 2,089 ​ $ 652 ​ $ 13,888 ​ ​ The following tables provide information on impaired loans and any related allowance by loan class as of March 31, 2021 and December 31, 2020.

These deferrals were no more than six months in duration and were for loans not more than 30 days past due as of March 31, 2021. As such, they were not considered TDRs based on the relief provisions of the CARES Act and recent interagency regulatory guidance. There were no TDRs which subsequently defaulted within 12 months of modification for the three months ended March 31, 2021 and 2020. Generally, a loan is considered in default when principal or interest is past due 90 days or more, the loan is placed on nonaccrual, the loan is charged off, or there is a transfer to OREO or repossessed assets. Management uses risk ratings as part of its monitoring of the credit quality in the Company’s loan portfolio. Loans that are identified as special mention, substandard or doubtful are adversely rated. These loans and the pass/watch loans are assigned higher qualitative factors than favorably rated loans in the calculation of the formula portion of the allowance for credit losses.

Fair Value Measurements

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 12 – 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 and to determine fair value disclosures. Securities available for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, loans held for sale and other real estate owned (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. Below is a discussion on the Company’s assets measured at fair value on a recurring basis. Investment Securities Available for Sale Fair value measurement for investment securities available for sale 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 agencies 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 on-line 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. The tables below present the recorded amount of assets measured at fair value on a recurring basis at March 31, 2021 and December 31, 2020. No assets were transferred from one hierarchy level to another during the first three months of 2021 or 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Other ​ Significant ​ ​ ​ ​ ​ Quoted ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Prices ​ Inputs ​ Inputs (Dollars in thousands) Fair Value (Level 1) (Level 2) (Level 3) March 31, 2021 ​ ​ ​ ​ Securities available for sale: ​ ​ ​ ​ U.S. Government agencies ​ $ 18,149 ​ $ — ​ $ 18,149 ​ $ — Mortgage-backed ​ 105,954 ​ — ​ 105,954 ​ — ​ ​ 124,103 ​ — ​ 124,103 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity ​ 1,382 ​ — ​ 1,382 ​ — Total ​ $ 125,485 ​ $ — ​ $ 125,485 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Other ​ Significant ​ ​ ​ ​ ​ Quoted ​ Observable ​ Unobservable ​ ​ ​ ​ ​ Prices ​ Inputs ​ Inputs (Dollars in thousands) Fair Value (Level 1) (Level 2) (Level 3) December 31, 2020 ​ ​ ​ ​ Securities available for sale: ​ ​ ​ ​ U.S. Government agencies ​ $ 23,537 ​ $ — ​ $ 23,537 ​ $ — Mortgage-backed ​ 116,031 ​ — ​ 116,031 ​ — ​ ​ 139,568 ​ — ​ 139,568 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity ​ 1,395 ​ — ​ 1,395 ​ — Total ​ $ 140,963 ​ $ — ​ $ 140,963 ​ $ — ​ Below is a discussion on the Company’s assets measured at fair value on a nonrecurring basis. Impaired Loans Loans are considered impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts according to the contractual terms of the loan agreement when due. Loan impairment is measured using the present value of expected cash flows, the loan’s observable market price or the fair value of the collateral (less selling costs) if the loans are collateral dependent and these are considered Level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable. The value of business equipment, inventory and accounts receivable, discounted on management’s review and analysis. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and the client’s business. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the factors identified above. Valuation techniques are consistent with those techniques applied in prior periods. Other Real Estate Owned (Foreclosed Assets) Foreclosed assets are adjusted for fair value upon transfer of loans to foreclosed assets establishing a new cost basis. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value. The estimated fair value for foreclosed assets included in Level 3 are determined by independent market based appraisals and other available market information, less costs to sell, that may be reduced further based on market expectations or an executed sales agreement. If the fair value of the collateral deteriorates subsequent to the initial recognition, the Company records the foreclosed asset as a non-recurring Level 3 adjustment. Valuation techniques are consistent with those techniques applied in prior periods. ​ ​ ​ ​ ​ ​ ​ The following tables set forth the Company’s financial and nonfinancial assets subject to fair value adjustments (impairment) on a nonrecurring basis at March 31, 2021 and December 31, 2020, that are valued at the lower of cost or market. Assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantitative Information about Level 3 Fair Value Measurements ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted (Dollars in thousands) Fair Value Valuation Technique Unobservable Input Range Average (3) March 31, 2021 ​ ​ ​ ​ Nonrecurring measurements: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans ​ $ 617 Appraisal of collateral (1) Liquidation expense (2) 10% ​ (10%) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans ​ $ 419 Discounted cash flow analysis (1) Discount rate ​ 4% - 7.25% ​ (6%) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Other real estate owned ​ $ 205 Appraisal of collateral (1) Appraisal adjustments (2) 0% - 19% ​ (0%) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantitative Information about Level 3 Fair Value Measurements ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted (Dollars in thousands) Fair Value Valuation Technique Unobservable Input Range ​ Average (3) December 31, 2020 ​ ​ ​ ​ ​ Nonrecurring measurements: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans ​ $ 610 Appraisal of collateral (1) Liquidation expense (2) 10% ​ (10%) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Impaired loans ​ $ 1,110 Discounted cash flow analysis (1) Discount rate ​ 6% - 7.25% ​ (6%) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Other real estate owned ​ $ — Appraisal of collateral (1) Appraisal adjustments (2) 0% - 19% ​ (19%) ​ (1) (2) (3) ​ The carrying amounts and estimated fair values of the Company’s financial instruments not carried at fair value on the Company’s Consolidated Balance Sheets are presented in the following table.

Financial Instruments with Off-Balance Sheet Risk [Abstract]
Financial Instruments with Off-Balance Sheet Risk	​ Note 13 – Financial Instruments with Off-Balance Sheet Risk In the normal course of business, to meet the financial needs of its customers, the Bank is a party to financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit and standby letters of credit. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Letters of credit and other commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of the letters of credit and commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. The following table provides information on commitments outstanding at March 31, 2021 and December 31, 2020. ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in thousands) March 31, 2021 December 31, 2020 Commitments to extend credit ​ $ 244,543 ​ $ 248,607 Letters of credit ​ 7,365 ​ 7,944 Total ​ $ 251,908 ​ $ 256,551 ​

Revenue Recognition [Abstract]
Revenue Recognition	Note 14 – Revenue Recognition Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. 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. ​ 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 are primarily comprised of 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 are primarily comprised of debit and credit card income, ATM fees, merchant services income, and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as 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. The Company determined that rentals and renewals of safe deposit boxes will be recognized on a monthly basis consistent with the duration of the performance obligation. The following presents noninterest income from continuing operations, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the three months ended March 31, 2021 and 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For Three Months Ended ​ ​ ​ March 31, ​ (Dollars in thousands) 2021 2020 ​ Noninterest Income ​ ​ In-scope of Topic 606: ​ ​ Service charges on deposit accounts ​ $ 674 ​ $ 866 ​ Trust and investment fee income ​ 407 ​ 375 ​ Interchange income ​ ​ 869 ​ ​ 652 ​ Other noninterest income ​ 305 ​ 280 ​ Noninterest Income (in-scope of Topic 606) ​ 2,255 ​ 2,173 ​ Noninterest Income (out-of-scope of Topic 606) ​ 302 ​ 179 ​ Total Noninterest Income ​ $ 2,557 ​ $ 2,352 ​ ​ Contract Balances A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s noninterest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of March 31, 2021, and December 31, 2020, the Company did not have any significant contract balances.

Proposed Merger [Abstract]
Proposed Merger	Note 15 – Proposed Merger On March 3, 2021, the Company and Severn Bancorp, Inc. (“Severn”) entered into a definitive agreement for the Company to acquire the Maryland-based Severn. ​ This transaction will create the third largest community bank headquartered in Maryland. One of the primary reasons for the proposed acquisition of Severn was the ability to access and deploy excess capital and deposits into a high growth market, while also enhancing scale to drive efficiency and profitability. Additionally, this transaction will create a competitive position in the Columbia/Baltimore/Towson MSA, while filling in our current market footprint. ​ Under the terms of the agreement, Severn shareholders will receive 0.6207 shares of Shore common stock and $1.59 in cash for each share of Severn common stock. Upon closing, Shore shareholders will own approximately 59.6% of the combined Company and Severn will own approximately 40.4% of the combined Company. The transaction is still subject to satisfaction of customary closing conditions, including regulatory approvals and shareholder approval from Shore and Severn shareholders. The transaction is expected to close in the third quarter of 2021. ​ As of December 31, 2020, Severn had more than $950 million in assets and operated 7 full-service community banking offices throughout Anne Arundel County, Maryland. ​

Basis of Presentation [Abstract]
Basis of Presentation	​ The consolidated financial statements include the accounts of Shore Bancshares, Inc. and its subsidiary with all significant intercompany transactions eliminated. The consolidated financial statements conform to accounting principles generally accepted in the United States of America (“GAAP”) and to prevailing practices within the banking industry. The accompanying interim financial statements are unaudited; however, in the opinion of management all adjustments necessary to present fairly the consolidated financial position at March 31, 2021, the consolidated results of income and comprehensive income for the three months ended March 31, 2021 and 2020, changes in stockholders’ equity for the three months ended March 31, 2021 and 2020 and cash flows for the three months ended March 31, 2021 and 2020, have been included. All such adjustments are of a normal recurring nature. The amounts as of December 31, 2020 were derived from the 2020 audited financial statements. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for any other interim period or for the full year. This Quarterly Report on Form 10-Q should be read in conjunction with the Annual Report of Shore Bancshares, Inc. on Form 10-K for the year ended December 31, 2020. For purposes of comparability, certain immaterial reclassifications have been made to amounts previously reported to conform with the current period presentation. When used in these notes, the term “the Company” refers to Shore Bancshares, Inc. and, unless the context requires otherwise, its consolidated subsidiary, Shore United Bank (the “Bank”).
Risks and Uncertainties	Risks and Uncertainties ​ Since the novel coronavirus ("COVID-19") was declared a pandemic in March 2020, COVID-19 has significantly affected our communities, customers, and operations. COVID-19 continues to have a significant impact in 2021, however, the extent of its effects are dependent upon multiple factors, such as the extent of distribution and efficacy of vaccines, COVID-19 variants, pandemic-related restrictions, and government response, among others. As a result, the ultimate effects of COVID-19 over the longer term cannot be reasonably estimated at this time. Risks and uncertainties arising from the pandemic remain, primarily concerning the ability of customers to fulfill their financial obligations to the Company as well as potential operational disruptions and the ability of the Company to generate demand for its products and services. Accordingly, estimates used in the preparation of our financial statements may be subject to significant adjustments in future periods.
Recent Accounting Standards and Other Authoritative Guidance	Recent Accounting Standards and Other Authoritative Guidance ASU No. 2016-13 – In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. At the FASB’s October 16, 2019 meeting, the Board affirmed its decision to amend the effective date of this ASU for many companies. Public business entities that are SEC filers, excluding those meeting the smaller reporting company definition, will retain the initial required implementation date of fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. All other entities will be required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022 . The team is currently running a parallel simulation to its current incurred loss impairment model. The Company is continuing to evaluate the extent of the potential impact of this standard and continues to keep current on evolving interpretations and industry practices via webcasts, publications, conferences, and peer bank meetings. ​ Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin (SAB) 119. SAB 119 updated portions of SEC interpretative guidance to align with FASB ASC 326, “Financial Instruments – Credit Losses.” It covers topics including (1) measuring current expected credit losses; (2) development, governance, and documentation of a systematic methodology; (3) documenting the results of a systematic methodology; and (4) validating a systematic methodology. ​ ASU No. 2020-04 – In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-bank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. At present, the Bank has limited exposure to LIBOR based pricing. LIBOR based loans only comprise 28 loans or 7.9% of the loan portfolio. The Bank is confident it can successfully negotiate a migration to the Secured Overnight Financing Rate (“SOFR”) between now and the implementation date. The Bank will notify customers within 120 days prior to migration to SOFR. The Bank acknowledges the replacement rate will be more volatile based on different countries migrating to different indexes and limited liquidity to support the rate. The Bank further acknowledges the volatility will be greatly influenced by the support provided by the Federal Reserve. ​ In October 2020, the FASB issued ASU 2020-08, “Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable fees and Other Costs.” This ASU clarifies that an entity should reevaluate whether a callable debt security is within the scope of ASC paragraph 310-20-35-33 for each reporting period. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is not permitted. All entities should apply ASU No. 2020-08 on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. The Company does not expect the adoption of ASU 2020-08 to have a material impact on its consolidated financial statements. ​ Recently Adopted Accounting Developments ​ ASU No. 2019-12 – In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes.” The ASU is expected to reduce cost and complexity related to the accounting for income taxes by removing specific exceptions to general principles in Topic 740 (eliminating the need for an organization to analyze whether certain exceptions apply in a given period) and improving financial statement preparers’ application of certain income tax-related guidance. This ASU is part of the FASB’s simplification initiative to make narrow-scope simplifications and improvements to accounting standards through a series of short-term projects. The amendments were effective in the first quarter of 2021 for the Company and there was no material impact on the Company’s Consolidated Financial Statements. ​ ASU No. 2020-01 – In January 2020, the FASB issued ASU 2020-01, “Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321, Topic 323, and Topic 815.” The ASU is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. ASU 2016-01 made targeted improvements to accounting for financial instruments, including providing an entity the ability to measure certain equity securities without a readily determinable fair value at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Among other topics, the amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting. The amendments were effective in the first quarter of 2021 for the Company and there was no material impact on the Company’s Consolidated Financial Statements.

Award description	The Company may issue shares of common stock or grant other equity-based awards pursuant to the 2016 Equity Plan. Stock-based awards granted to date generally are time-based, vest in equal installments on each anniversary of the grant date and range over a one- to five-year period of time, and, in the case of stock options, expire 10 years from the grant date. As part of the 2016 Equity Plan, a performance equity incentive award program, known as the “Long-term incentive plan” allows participating officers of the Company to earn incentive awards of performance share/restricted stock units if certain pre-determined targets are achieved at the end of a three-year performance cycle. Stock-based compensation expense based on the grant date fair value is recognized ratably over the requisite service period for all awards and reflects forfeitures as they occur.
