(we, us, our, Powell or the Company) was incorporated in the state of Delaware in 2004 as a successor to a Nevada company incorporated in 1968. The Nevada company was the successor to a company founded by William E. Powell in 1947, which merged into the Company in 1977. Our major subsidiaries, all of which are wholly owned, include: Powell Electrical Systems, Inc.; Powell (UK) Limited; Powell Canada Inc.; and Powell Industries International, B.V.</span></div><div style="margin-top:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We develop, design, manufacture and service custom-engineered equipment and systems which (1) distribute, control and monitor the flow of electrical energy and (2) provide protection to motors, transformers and other electrically powered equipment. Our principal products include integrated power control room substations (PCRs®), custom-engineered modules, electrical houses (E-Houses), traditional and arc-resistant distribution switchgear and control gear, medium-voltage circuit breakers, monitoring and control communications systems, motor control centers, switches and bus duct systems. These products are designed for application voltages ranging from 480 volts to 38,000 volts. Our products are used in the oil and gas markets, onshore and offshore production, liquefied natural gas (LNG) facilities and terminals, pipeline, refineries and petrochemical plants. Additionally, we manufacture products for the electric utility, light rail traction power as well as mining and metals, pulp and paper and other municipal, commercial and other industrial markets. Our product scope includes designs tested to meet both United States (U.S.) and international standards, under both the American National Standards Institute (ANSI) and International Electrotechnical Commission (IEC). We assist customers by providing field service inspection, installation, commissioning, modification, and repair services, as well as spare parts, retrofit and retrofill components for existing systems and replacement circuit breakers for obsolete switchgear no longer produced by the original manufacturer. We seek to establish long-term relationships with the end users of our systems as well as the design and construction engineering firms contracted by those end users. We believe that our culture of safety and focus on customer satisfaction, along with our financial strength, allow us to continue to capitalize on opportunities in the industries we serve.</span></div><div style="margin-top:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">References to Fiscal 2022, Fiscal 2021 and Fiscal 2020 used throughout these Notes to Consolidated Financial Statements relate to our fiscal years ended September 30, 2022, 2021 and 2020, respectively.</span></div><div style="margin-top:12pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Impact of </span><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Oil and Gas Commodity Market</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"> Volatility </span><span style="background-color:#ffffff;color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">on Powell</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The consequences of a prolonged global macro-economic decline could include, but are not limited to, a continued reduction in commercial and industrial activity. Accordingly, the Company cannot reasonably estimate the duration or severity of a potential decline in demand, or the extent to which the disruption may materially impact our business, results of operations or cash flows. We will take prudent measures to maintain our strong liquidity and cash position, which may include reducing our capital expenditures and research and development costs, as well as reducing or eliminating future dividend payments.</span></div>

The most significant estimates used in our consolidated financial statements affect revenue recognition and estimated cost recognition on our customer contracts, the 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 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 </span></div>deductible. Estimates routinely change as new events occur, additional information becomes available or operating environments change. Actual results may differ from our prior estimates.
