Business Description and Accounting Policies [Text Block]	1. Description of Business and Summary of Significant Accounting Policies Steele Bancorp, Inc. (the Bancorp) is a Pennsylvania Corporation organized as the holding company of Central Penn Bank & Trust (the Bank) (collectively, the "Company"). The Bank is a state chartered commercial bank located in Mifflinburg, Pennsylvania, whose principal sources of revenues are derived from its commercial, mortgage, residential real estate, and consumer loan financing as well as a variety of deposit services provided to customers serviced by its thirteen offices. Milestone Insurance Services, LLC (Milestone) was formed in 2003 and is a wholly owned subsidiary of the Bank. Milestone is licensed to sell title insurance. The Bancorp is supervised by the Board of Governors of the Federal Reserve System while the Bank is subject to regulation and supervision by the Federal Deposit Insurance Company and the Pennsylvania Department of Banking and Securities. *Basis of Presentation* The accompanying unaudited consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles ("GAAP") for interim reporting and with applicable quarterly reporting regulations for the U.S. Securities and Exchange Commission ("SEC"). They do not include all of the information and notes required by GAAP for complete financial statements. As such, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto as of and for the year ended December 31, 2024, included in the Company's Special Financial Report on Form 10-K for the year ended December 31, 2024 ("2024 Form 10-K"). Application of the principles of GAAP and practices within the banking industry requires management to make estimates, assumptions and judgements that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgements are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements may reflect different estimates, assumptions and judgements. Certain policies inherently rely more extensively on the use of estimates, assumptions, and judgements and as such may have a greater possibility of producing results that could be materially different than originally reported. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses on loans and acquisition accounting. The results of operations for the three and nine months ended September 30, 2025, is not necessarily indicative of results of operations for the full year or any other interim period. The Company's significant accounting policies followed in preparation of the unaudited consolidated financial statements are disclosed in Note 1 of the 2024 Form 10-K. In addition to applying significant accounting policies disclosed in Note 1 of the 2024 Form 10-K, the Company implemented accounting policies appropriate for its merger with Northumberland Bancorp (“NUBC”). Business combinations are accounted for under Accounting Standards Codification (“ASC”) 805, Business Combinations, using the acquisition method of accounting. The acquisition method of accounting requires an acquirer to recognize the assets acquired and the liabilities assumed at the acquisition date measured at their fair values as of that date. To determine the fair values, the Company relies on internal or third-party valuations, such as appraisals, valuations based on discounted cash flow analyses, or other valuation techniques. Under the acquisition method of accounting, the Company identifies the acquirer and the closing date and applies applicable recognition principles and conditions. Acquisition-related costs are costs the Company incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees. Some other examples of costs to the Company include systems conversions, integration planning consultants and advertising costs. The Company accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received, with one exception. The costs to issue debt or equity securities are recognized in accordance with other applicable GAAP. These acquisition-related costs have been and will be included within the consolidated statements of income classified within the noninterest expenses caption. The most significant assessment of fair value in the Company’s accounting for business combinations relates to the valuation of an acquired loan portfolio. At acquisition, loans are classified as either (i) purchase credit-deteriorated (“PCD”) loans or (ii) non-PCD loans and are recorded at fair value on the date of acquisition. PCD loans are those for which there is more than insignificant evidence of credit deterioration since origination. Fair values are determined primarily through a discounted cash flow approach which considers the acquired loans’ underlying characteristics, including account types, remaining terms, annual interest rates, interest types, timing of principal and interest payments, current market rates, and remaining balances. Estimates of fair value also include estimates of default, loss severity, and estimated prepayments. At acquisition, an allowance for credit losses (“ACL”) for PCD loans is determined based upon the Company’s methodology for estimating the ACL on loans. This allowance is credited to the ACL on loans with a corresponding adjustment to the amortized cost basis of the loan on the date of the acquisition. The difference between the new amortized cost basis and the unpaid principal balance is either a noncredit discount or premium that is amortized or accreted to interest income over the remaining life of the loan. Disposals of PCD loans, which may include sale of loans to third parties, receipt of payments in full or in part from the borrower or foreclosure of the collateral, result in removal of the loan from the loan portfolio at its carrying amount. For non-PCD loans, an ACL is established in a manner that is consistent with the Company’s originated loans. The ACL is determined using the Company’s methodology and the related ACL for non-PCD loans is recorded through a charge to the provision for credit losses in the period in which the loans are purchased or acquired. The entirety of any purchase discount or premium on non-PCD loans is amortized or accreted to interest income over the remaining life of the loan. In accordance with ASC 805, the Company also identified intangible assets acquired. Other intangible assets lack physical substance but have contractual or other legal rights or are capable of being sold or exchanged either on their own or in combination with a related contract, asset or liability. Intangible assets are initially recorded at fair value. Determining fair value is subjective, requiring the use of estimates, assumptions and management judgment. Intangible assets that have finite lives are amortized over their estimated useful lives and are subject to impairment testing. Upon acquisition of NUBC, the Company recognized a core deposit intangible asset, which represents the value of customer deposit relationships. Core deposit intangible assets are amortized over an estimated useful life of 10 years using an accelerated method which approximates the estimated attrition of the acquired deposits. Certain items in the prior period financial statement have been reclassified to conform to the current presentation. These reclassifications had no effect on prior year net income or stockholder's equity. The accounting policies followed by the Company and the methods of applying these policies conform with accounting principles generally accepted in the United States of America (GAAP) and with general practices within the banking industry. All significant intercompany accounts and transactions between the Company and its subsidiary have been eliminated. The accompanying interim period financial statements are unaudited; however, in the opinion of the Company's management, all adjustments consisting of normal recurring adjustments, which are necessary for a fair presentation of the consolidated financial statements have been included. *Recent Accounting Pronouncements* In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 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 2023-09 to have a material impact on its consolidated financial statements. In November 2024, the Financial Accounting Standards Board (FASB) issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires public companies to disclose, in the notes to the financial statements, specified information about certain costs and expenses at each interim and annual reporting period. This includes disclosing amounts related to employee compensation, depreciation, and intangible asset amortization. In addition, public companies will need to provide qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. ASU 2024-03 is effective for public business entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Implementation of ASU 2024-03 may be applied prospectively or retrospectively. The Company does not expect the adoption of ASU 2024-03 to have a material impact on its consolidated financial statements. In January 2025, the Financial Accounting Standards Board (FASB) issued ASU 2025-01, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date.” ASU 2025-01 amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of Update ASU 2024-03 is permitted. The Company does not expect the adoption of ASU-2025-01 to have a material impact on its consolidated financial statements. *Common stock held by ESOP* The Company classifies equity securities as temporary equity if those securities are redeemable at the option of the holder or upon the occurrence of an event not solely within the issuer control. Thus, shares of common stock held by an ESOP, whether non-leveraged or leveraged, that are redeemable at the option of the participant must be classified within temporary equity and classified as Redeemable Common Stock Held By Employee Stock Ownership Plan. Changes in the value of the redeemable ESOP shares are recognized in the Maximum Cash Obligation Related to ESOP shares as a component of stockholders’ equity. The Company’s maximum cash obligations related to these shares is classified outside stockholders’ equity because the shares are not readily traded and could be put to the Company for cash.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with Generally Accepted Accounting Principles ("GAAP") for interim reporting and with applicable quarterly reporting regulations for the U.S. Securities and Exchange Commission ("SEC"). They do not include all of the information and notes required by GAAP for complete financial statements.

Recent Accounting Pronouncements

In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 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 2023-09 to have a material impact on its consolidated financial statements.

In November 2024, the Financial Accounting Standards Board (FASB) issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires public companies to disclose, in the notes to the financial statements, specified information about certain costs and expenses at each interim and annual reporting period. This includes disclosing amounts related to employee compensation, depreciation, and intangible asset amortization. In addition, public companies will need to provide qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. ASU 2024-03 is effective for public business entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027.

In January 2025, the Financial Accounting Standards Board (FASB) issued ASU 2025-01, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date.” ASU 2025-01 amends the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption of Update ASU 2024-03 is permitted. The Company does not expect the adoption of ASU-2025-01 to have a material impact on its consolidated financial statements.

Common stock held by ESOP

The Company classifies equity securities as temporary equity if those securities are redeemable at the option of the holder or upon the occurrence of an event not solely within the issuer control. Thus, shares of common stock held by an ESOP, whether non-leveraged or leveraged, that are redeemable at the option of the participant must be classified within temporary equity and classified as Redeemable Common Stock Held By Employee Stock Ownership Plan. Changes in the value of the redeemable ESOP shares are recognized in the Maximum Cash Obligation Related to ESOP shares as a component of stockholders’ equity.

The Company’s maximum cash obligations related to these shares is classified outside stockholders’ equity because the shares are not readily traded and could be put to the Company for cash.
