Business Description and Basis of Presentation [Text Block] | 1. BUSINESS AND ACCOUNTING POLICIES Description of the Business IES Holdings, Inc. designs and installs integrated electrical and technology systems and provides infrastructure products and services to a variety of end markets, including data centers, residential housing and commercial and industrial facilities. Our operations are organized into four business segments, based upon the nature of our services: •Communications – Nationwide provider of technology infrastructure services, including the design, build, and maintenance of the communications infrastructure within data centers for co-location and managed hosting customers, for both large corporations and independent businesses. •Residential – Regional provider of electrical installation services for single-family housing and multi-family apartment complexes, as well as heating, ventilation and air conditioning (HVAC) and plumbing installation services in certain markets. •Infrastructure Solutions – Provider of electro-mechanical solutions for industrial operations, including apparatus repair and custom-engineered products such as generator enclosures used in data centers and other industrial applications. •Commercial & Industrial – Provider of electrical and mechanical design, construction, and maintenance services to the commercial and industrial markets in various regional markets and nationwide in certain areas of expertise, such as the power infrastructure market and data centers. The words “IES”, the “Company”, “we”, “our”, and “us” refer to IES Holdings, Inc. and, except as otherwise specified herein, to our consolidated subsidiaries. Seasonality and Quarterly Fluctuations Results of operations from our Residential segment can be seasonal, depending on weather trends, with typically higher revenues generated during spring and summer and lower revenues generated during fall and winter. The Commercial & Industrial, Communications and Infrastructure Solutions segments of our business are less subject to seasonal trends, as work in these segments generally is performed inside structures protected from the weather, although weather can still impact these businesses, especially in the early stages of projects. From quarter to quarter, results for our Communications, Residential, and Commercial & Industrial segments may be materially affected by the timing of new construction projects, and our volume of business may be adversely affected by declines in construction projects resulting from adverse regional or national economic conditions. Quarterly results for our Infrastructure Solutions segment may be affected by the timing of outages or capital projects at our customers’ facilities. Accordingly, operating results for any fiscal period are not necessarily indicative of results that may be achieved for any subsequent fiscal period. Basis of Financial Statement Preparation The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of IES, our wholly-owned subsidiaries, and entities that we control due to ownership of a majority of voting interest and have been prepared in accordance with the instructions to interim financial reporting as prescribed by the United States Securities and Exchange Commission (the “SEC”). The results for the interim periods are not necessarily indicative of results for the entire year. These interim financial statements do not include all disclosures required by U.S. generally accepted accounting principles (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto filed with the SEC in our Annual Report on Form 10-K for the fiscal year ended September 30, 2024. In the opinion of management, the unaudited Condensed Consolidated Financial Statements contained in this report include all known accruals and adjustments necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods reported herein. Any such adjustments are of a normal recurring nature. Income Taxes On July 4, 2025, the U.S. enacted the One Big Beautiful Bill Act (“Act”), a comprehensive legislative package that includes significant changes to federal tax policy. The Act, among other corporate provisions, includes the permanent extension of 100% bonus depreciation and the repeal of mandatory capitalization of domestic research and experimental expenditures. The Company is currently assessing the impact the Act will have on our overall financial results, financial position, and cash flows. Equity Method Investments We account for investments using the equity method of accounting if the investment gives us the ability to exercise significant influence over an investee but does not grant us control. Significant influence generally exists when an investor owns 20% or more of the voting stock of an incorporated investee or a more than 3% to 5% interest in an unincorporated investee. Under the equity method of accounting, the carrying amount of an investment is initially recorded at cost basis and is subsequently adjusted for our proportionate share of earnings or losses, additional investments in the entity, and distributions. Our proportionate share of earnings or losses is recorded in earnings on our Condensed Consolidated Statements of Comprehensive Income. Noncontrolling Interest In connection with our acquisitions of Edmonson Electric, LLC (“Edmonson Electric”) and Bayonet Plumbing, Heating & Air-Conditioning, LLC (“Bayonet”) in fiscal 2021, and NEXT Electric, LLC in fiscal 2017, we acquired an 80 percent interest in each of the entities, with the remaining 20 percent interest in each such entity being retained by the respective third-party seller. The interests retained by those third-party sellers are identified on our Condensed Consolidated Balance Sheets as “Noncontrolling interest,” classified outside of permanent equity. On June 28, 2024, we acquired the remaining 20 percent noncontrolling interest in Bayonet for $32,000. Under the terms of each entity’s operating agreement, after five years from the date of the acquisition, we may elect to purchase, or the third-party seller may require us to purchase, part or all of the remaining 20 percent interest in the applicable entity. In each case, the purchase price is variable, based on a multiple of earnings as defined in the applicable operating agreement. Therefore, each noncontrolling interest is carried at the greater of the balance determined under Accounting Standards Codification (“ASC”) 810 and the redemption amounts assuming the noncontrolling interest was redeemable at the balance sheet date. If all of the noncontrolling interests remaining outstanding at June 30, 2025 had been redeemable at that date, the aggregate redemption amount would have been $40,977. The activity in redeemable noncontrolling interest for the nine months ended June 30, 2025 and 2024 is summarized in the table below.

On July 1, 2025, we acquired the remaining 20 percent noncontrolling interest in Edmonson Electric for $40,000. Use of Estimates The preparation of financial statements in conformity with GAAP requires the use of estimates and assumptions by management in determining the reported amounts of assets and liabilities, disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates are primarily used in our revenue recognition of construction in progress, fair value assumptions in accounting for business combinations, stock-based compensation, reserves for legal matters, and realizability of deferred tax assets and unrecognized tax benefits.
Accounting Standards Update and Change in Accounting Principle | In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). This standard amends the existing guidance under ASC 805 to add contract assets and contract liabilities to the list of exceptions to the recognition and measurement principles that apply to business combinations. Under this standard, the acquirer of a business is expected to recognize and measure acquired contract assets and contract liabilities as if the acquirer entered into the original contract on the same date with the same terms in accordance with ASC 606 rather than at fair value on the date of acquisition. This update is effective for fiscal years beginning after December 15, 2022 and for interim periods within that year. We adopted this standard on October 1, 2023 using the prospective method. ASU 2021-08 impacts how we account for business combinations completed after its adoption. Recent Accounting Pronouncements and Disclosure Rules Not Yet Adopted In November 2023, the FASB issued Accounting Standard Update No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). This standard requires disclosure of significant segment expenses, other segment items, and additional information about the chief operating decision maker (“CODM”). This update is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, and retrospective application is required. We are evaluating the impact this update will have on our annual disclosures; however, it will not impact our financial condition, results of operations, or cash flows. In December 2023, the FASB issued Accounting Standard Update No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). This standard requires more detailed disclosure within the tax rate reconciliation table, as well as additional information about cash taxes paid. This update is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. We are evaluating the impact this update will have on our annual disclosures; however, it will not impact our financial condition, results of operations, or cash flows. In November 2024, the FASB issued Accounting Standard Update No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”). This standard requires additional disclosures of certain expenses, including purchases of inventory, employee compensation, depreciation, intangible asset amortization, and other specific expense categories. This standard also requires disclosure of the total amount of selling expenses and the Company's definition of selling expenses. This update is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. We are evaluating the impact this update will have on our annual disclosures; however, it will not impact our financial condition, results of operations, or cash flows.
Noncontrolling Interest Disclosure | Noncontrolling Interest In connection with our acquisitions of Edmonson Electric, LLC (“Edmonson Electric”) and Bayonet Plumbing, Heating & Air-Conditioning, LLC (“Bayonet”) in fiscal 2021, and NEXT Electric, LLC in fiscal 2017, we acquired an 80 percent interest in each of the entities, with the remaining 20 percent interest in each such entity being retained by the respective third-party seller. The interests retained by those third-party sellers are identified on our Condensed Consolidated Balance Sheets as “Noncontrolling interest,” classified outside of permanent equity. On June 28, 2024, we acquired the remaining 20 percent noncontrolling interest in Bayonet for $32,000. Under the terms of each entity’s operating agreement, after five years from the date of the acquisition, we may elect to purchase, or the third-party seller may require us to purchase, part or all of the remaining 20 percent interest in the applicable entity. In each case, the purchase price is variable, based on a multiple of earnings as defined in the applicable operating agreement. Therefore, each noncontrolling interest is carried at the greater of the balance determined under Accounting Standards Codification (“ASC”) 810 and the redemption amounts assuming the noncontrolling interest was redeemable at the balance sheet date. If all of the noncontrolling interests remaining outstanding at June 30, 2025 had been redeemable at that date, the aggregate redemption amount would have been $40,977. The activity in redeemable noncontrolling interest for the nine months ended June 30, 2025 and 2024 is summarized in the table below.
