Accounting Policies [Abstract] |
Overview and Summary of Significant Accounting Policies | Overview and Summary of Significant Accounting Policies Overview Powell Industries, Inc. (we, us, our, Powell or the Company) is a Delaware corporation founded by William E. Powell in 1947. We develop, design, manufacture and service custom-engineered equipment and systems that distribute, control and monitor the flow of electrical energy and provide protection to motors, transformers and other electrically powered equipment. Our major subsidiaries, all of which are wholly owned, include Powell Electrical Systems, Inc.; Powell Canada Inc.; Powell (UK) Limited; and Powell Industries International, B.V. We are headquartered in Houston, Texas and primarily serve the oil and gas and petrochemical markets, the electric utility market, and commercial and other industrial markets. Beyond these major markets, we also provide products and services to the light rail traction power market and other markets that include universities and government entities. We are continuously developing new channels to electrical markets through original equipment manufacturers and distribution market channels. Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of Powell and our wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP), have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the interim condensed consolidated financial statements have been included. The results of operations for the interim periods are not necessarily indicative of the results for the entire fiscal year. We believe that these financial statements contain all adjustments necessary so that they are not misleading. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto of Powell and its subsidiaries included in Powell’s Annual Report on Form 10-K for the year ended September 30, 2024, which was filed with the Securities and Exchange Commission (SEC) on November 20, 2024. References to Fiscal 2025 and Fiscal 2024 used throughout this report shall mean the current fiscal year ending September 30, 2025 and the prior fiscal year ended September 30, 2024, respectively. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying footnotes. The most significant estimates used in our condensed consolidated financial statements affect revenue recognition and estimated cost recognition on our customer contracts, allowance for credit losses, provision for excess and obsolete inventory, warranty accruals and income taxes. The amounts recorded for warranties, legal, income taxes, impairment of long-lived assets (when applicable), liquidated damages and other contingent liabilities require judgments regarding the amount of expenses that will ultimately be incurred. We base our estimates on historical experience, forecasts and various other assumptions, as well as the specific circumstances surrounding these contingent liabilities, in evaluating the amount of liability that should be recorded. Additionally, the basis for recognition of deferred tax assets requires estimates related to future income and other assumptions regarding timing and future profitability because the ultimate realization of net deferred tax assets is dependent on the generation of future taxable income during periods in which temporary differences become deductible. Estimates routinely change as new events occur, additional information becomes available or operating environments change. Actual results may differ from our prior estimates. Accounting Standards Updates and Disclosure Rules Issued but Not Yet Adopted In November 2023, the Financial Accounting Standard Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires that public entities disclose significant segment expenses that are regularly provided to the chief operating decision maker (CODM) on an annual and interim basis. It also requires that public entities disclose the title and position of the CODM and an explanation of how the CODM uses the reported measures in assessing segment performance and resource allocation. Additionally, it requires that all existing annual disclosures about segment profit or loss and assets must be provided on an interim basis and clarifies that single reportable segment entities are subject to the disclosure requirement under Topic 280 in its entirety. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. A public entity should apply ASU 2023-07 retrospectively to all prior periods presented in the financial statements. Early adoption is permitted. We will implement the new disclosure requirements beginning with our Fiscal 2025 Form 10-K. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which enhances the transparency of income tax disclosures. It requires greater disaggregation of information in the tax rate reconciliation and income taxes paid disaggregated by jurisdiction. This ASU is effective for fiscal years beginning after December 15, 2024, and should be applied on a prospective basis. Retrospective application and early adoption are permitted. We are currently evaluating the impacts of the new standard. In November 2024, the FASB issued ASU No. 2024-03, Reporting Comprehensive Income – Expense Disaggregation Disclosures, which requires additional qualitative and quantitative information about specific expense categories in the notes to financial statements for both interim and annual reporting periods. In January 2025, the FASB further clarified the effective date for interim reporting periods. This ASU is effective for fiscal years beginning after December 15, 2026 and interim periods within those fiscal years beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impacts of the new standard.
