Management is actively involved in monitoring exposure to market risk and continues to develop and utilize appropriate risk management techniques. Our exposure to significant market risks includes fluctuations in labor costs and commodity prices. We are also exposed to interest rate risk with respect to any debt obligations we may incur under our revolving credit facility. For additional information see “Disclosure Regarding Forward-Looking Statements” in Part I of this Quarterly Report on Form 10-Q and our risk factors in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 30, 2025. Commodity Risk Our exposure to significant market risks includes fluctuations in commodity prices for, among other things, copper, aluminum, steel, electrical components, certain plastics and fuel. Commodity price risks may have an impact on our results of operations due to the fixed-price nature of many of our contracts. Over the long term, we expect to be able to pass along a portion of these costs to our customers, as market conditions in the industries we serve will allow. Investment Risk We are exposed to market price volatility for our investments in marketable securities which are carried at fair value measured using market prices, with gains and losses included under "Interest and other income (expense)" on our Condensed Consolidated Statements of Comprehensive Income. Changes in the market value of these investments could create volatility in our reported earnings from period to period, and a decline in value of our investments could have an adverse impact on our reported earnings. Changes in market value of these investments measured at fair value resulted in an unrealized gain of $56.1 million in the nine months ended June 30, 2026. As of June 30, 2026, we had investments in marketable securities with a fair value of $310.6 million, and a 10% increase or decrease in the market value of these investments would cause a $31.1 million increase or decrease, respectively, to the carrying value of our investments in marketable securities and our pre-tax income. The hypothetical 10% increase or decrease does not represent the maximum extent to which the fair value of our investments could be affected by changes in market conditions. Our investments could decline in value by a far greater amount as a result of volatility in the equity markets and the concentrated nature of our investment portfolio. Interest Rate Risk Floating rate debt, where the interest rate fluctuates periodically, exposes us to short-term changes in market interest rates. Any borrowings under our revolving credit facility are structured on floating rate terms. We currently do not maintain any hedging contracts that would limit our exposure to variable rates of interest when we have outstanding borrowings under our revolving credit facility. The Amended Credit Agreement uses SOFR as the benchmark for establishing the interest rate charged on our borrowings. If SOFR were to increase, our interest payment obligations on any then-outstanding borrowings would increase, having a negative effect on our cash flow and financial condition. We had no borrowings outstanding under our revolving credit facility as of June 30, 2026.
