Accounting Policies [Abstract]
Nature of Business and Basis of Presentation	Note 1 - Nature of Business and Basis of Presentation Nature of operations: Capital Bancorp, Inc. is a Maryland corporation and the bank holding company (the “Company”) for Capital Bank, N.A. (the “Bank”). The Company's primary operations are conducted by the Bank, which is headquartered in Rockville, Maryland. The Company operates three additional divisions including, OpenSky™, Windsor Advantage, LLC (“Windsor Advantage™”) and Capital Bank Home Loans (“CBHL”). The Company serves businesses, not-for-profit associations, entrepreneurs and others throughout Washington D.C., Baltimore, other Maryland markets, Delaware, Florida, Illinois and North Carolina through seven commercial bank branches, one mortgage banking office, three loan production offices, three government loan servicing offices, and one credit card operations office. The Bank is principally engaged in providing commercial, real estate, and credit card loans along with other banking services, and attracting deposits. The Company issues credit cards through OpenSky™, a digitally-driven, nationwide credit card platform providing secured, partially secured, and unsecured credit solutions. Windsor Advantage™, a wholly-owned subsidiary of the Company, is a loan service provider that offers community banks and credit unions a comprehensive U.S. Small Business Administration (“SBA”) 7(a) and U.S. Department of Agriculture (“USDA”) lending platform. The Company originates residential mortgages for sale in the secondary market through CBHL, the Bank’s residential mortgage banking arm. In addition, the Company owns all of the stock of Capital Bancorp (MD) Statutory Trust I (the “Trust”). The Trust is a special purpose non-consolidated entity organized for the sole purpose of issuing trust preferred securities. Basis of presentation: The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with rules and regulations of the Securities and Exchange Commission (“SEC”) and conform to general practices within the banking industry. The consolidated financial statements include the activity of the Company and its wholly-owned subsidiaries, the Bank, Windsor Advantage™, and Church Street Capital, LLC (“CSC”). The statements do not include all of the information and footnotes required by GAAP for complete financial statements. All adjustments have been made which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods presented. Such adjustments are all of a normal and recurring nature. All significant inter-company accounts and transactions have been eliminated in consolidation. The results of operations for the three and nine months ended September 30, 2026 are not necessarily indicative of the results that may be expected for the full year. The December 31, 2025 consolidated balance sheet was derived from audited financial statements. These unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto as of December 31, 2025, included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The Company reports its activities as four divisions and reporting segments: Commercial Banking, OpenSky™, Windsor Advantage™, and Capital Bank Home Loans. In determining the appropriateness of segment definition, the Company considers components of the business about which financial information is available and regularly evaluated relative to resource allocation and performance assessment. Note 1 - Nature of Business and Basis of Presentation Significant accounting policies: The preparation of consolidated financial statements in accordance with GAAP requires estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. The primary reference point for the estimates is on historical experience and assumptions believed to be reasonable regarding the value of certain assets and liabilities that are not readily available from other sources. Estimates are evaluated on an ongoing basis. Actual results may materially differ from these estimates under different assumptions or conditions. The Company’s significant accounting policies are described in the “Notes to the Consolidated Financial Statements” included in our Annual Report on Form 10-K for the year ended December 31, 2025. There have been no changes to our significant accounting policies during the three and nine months ended September 30, 2026. Recently Issued Accounting Pronouncements: In October 2023, the FASB issued Accounting Standards Update 2023-06, “Disclosure Improvements: Codification Amendments Response to the SEC’s Disclosure Update and Simplification Initiative" ("ASU 2023-06"). ASU 2023-06 incorporates several U.S. SEC disclosure requirements under Regulations S-K and S-X. The amendments in the ASU are intended to clarify or improve disclosure and presentation requirements of a variety of Codification Topics, allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the requirements, and align the requirements in the Codification with the SEC’s regulations. These requirements are similar to, but require additional information than, generally accepted accounting principles. These new updates modify the disclosure or presentation requirements of a variety of Topics in the Codification. Entities should apply the amendments in ASU 2023-06 prospectively. For entities subject to the SEC’s existing disclosure requirements and for entities that have to file or provide financial statements with or to the SEC for the purpose of selling or issuing securities that do not have contractual limits on transfer, the effective date for each amendment will be the date on which the SEC removes that related disclosure from its rules. As a result, the effective date will be different for each individual disclosure based on the effective date of the SEC’s deletion of the related disclosure. Early adoption is prohibited. For all other entities, the effective date will be two years later. Early adoption is permitted for these entities, but not before the provisions of the ASU become effective for entities subject to SEC’s regulation. The effective dates of the amendments are predicated on the SEC removing its related disclosure requirements from its regulations. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendments will be removed from the Codification and not become effective for any entity. We are currently in the process of evaluating this guidance. In November 2024, the FASB issued Accounting Standards Update 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" ("ASU 2024-03"). ASU 2024-03 requires public entities to provide disaggregated disclosures, in the notes to the financial statements, of certain categories of expenses that are included in expense line items on the face of the income statement. ASU 2024-03 is effective for the Company for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company will update its expense disclosures upon adoption. In September 2025, the FASB issued Accounting Standards Update 2025-06 “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”). ASU 2025-06 makes targeted improvements to Subtopic 350-40 to increase the operability of the recognition guidance considering different methods of software Note 1 - Nature of Business and Basis of Presentation development. ASU 2025-06 is effective for the Company for fiscal years beginning after December 15, 2027, and interim reporting periods in those years, with early adoption permitted. The Company will update its software capitalization policy upon adoption. In November 2025, the FASB issued Accounting Standards Update 2025-08 “Financial Instruments - Credit Losses (Topic 326): Purchased Loans” (“ASU 2025-08”), which expands the gross-up approach applied to purchased credit deteriorated (“PCD”) loans in an acquisition to certain purchased financial assets, including certain seasoned loans that do not meet the definition of PCD. Upon adoption of this guidance, qualifying seasoned loans acquired in future transactions would be recorded by grossing up the purchase price for the initial allowance for credit losses rather than recognizing the allowance through provision expense at acquisition. As a result, future acquisitions may not generate the same level of initial provision expense and related earnings volatility associated with the historical accounting treatment. The guidance would be effective for the Company for fiscal years beginning after December 15, 2026, with early adoption permitted, and is to be applied prospectively. The Company is currently evaluating the impact of this standard and has not elected early adoption. In November 2025, the FASB issued Accounting Standards Update 2025-09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements” (“ASU 2025-09”). ASU 2025-09 is intended to clarify guidance on hedge accounting and to address several incremental hedge accounting issues arising from the global reference rate reform initiative. The guidance would be effective for the Company for fiscal years beginning after December 15, 2026, with early adoption permitted, and is to be applied prospectively. The Company is currently evaluating the impact of this standard and has not elected early adoption. In November 2025, the FASB issued Accounting Standards Update 2025-11, "Interim Reporting" ("ASU 2025-11"). ASU 2025-11 is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for the Company for interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact the adoption of ASU 2025-11 may have on the Company’s consolidated financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company's financial position, results of operations or cash flows. Reclassifications: Certain reclassifications have been made to amounts reported in prior periods to conform to the current period presentation. The reclassifications had no material effect on net income, total assets, total liabilities, or total stockholders' equity, or cash flows from operating activities. Certain prior period amounts in the consolidated statements of changes in stockholders’ equity have been reclassified to conform to the current period presentation. These reclassifications were made within total stockholders’ equity and had no impact on previously reported net income, earnings per share, or total stockholders’ equity. Note 1 - Nature of Business and Basis of Presentation Subsequent events: Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. For further information on a subsequent event related to the Company’s quarterly dividend, refer to Note 14.
