The Company is exposed to changes in interest rates as a result of its financing activities, primarily its borrowings on its revolving credit facility, if any, and investing activities with respect to investments held by the insurance segment. On June 30, 2026. and as previously disclosed in a Form 8-K filed with the SEC on July 6, 2026, Landstar entered into the Third Amended and Restated Credit Agreement, dated June 30, 2026, with a bank syndicate led by JPMorgan Chase Bank, N.A., as administrative agent, which amended and restated the existing second amended and restated credit agreement. The Third Amended and Restated Credit Agreement, which matures June 30, 2031, provides for borrowing capacity in the form of a revolving credit facility of $300,000,000, $100,000,000 of which may be utilized in the form of letters of credit. The Third Amended and Restated Credit Agreement also includes an uncommitted “accordion” feature permitting up to an additional $500,000,000 in increases to the revolving credit facility. The revolving credit loans under the Credit Agreement as of June 27, 2026, at the option of Landstar, bear interest at (i) a forward-looking term rate based on the secured overnight financing rate plus 0.10% and an applicable margin ranging from 1.25% to 2.00%, or (ii) an alternate base rate plus an applicable margin ranging from 0.25% to 1.00%, in each case with the applicable margin determined based upon the Company’s Leverage Ratio, as defined in the Credit Agreement, at the end of the most recent applicable fiscal quarter for which financial statements have been delivered. The revolving credit facility bears a commitment fee, payable quarterly in arrears, of 0.20% to 0.30%, based on the Company’s Leverage Ratio at the end of the most recent applicable fiscal quarter for which financial statements have been delivered. During the entire second quarter of 2026 and as of June 27, 2026 and December 27, 2025, the Company had no borrowings outstanding under the Credit Agreement. Long-term investments, all of which are available-for-sale and are carried at fair value, include investment-grade bonds and asset-backed securities having maturities of up to five years. Assuming that the long-term portion of investments remains at $95,748,000, the balance at June 27, 2026, a hypothetical increase or decrease in interest rates of 100 basis points would not have a material impact on future earnings on an annualized basis. Short-term investments consist primarily of short-term investment-grade instruments and the current maturities of investment-grade corporate bonds and asset-backed securities. Accordingly, any future interest rate risk on these short-term investments would not be material to the Company’s operating results. 34 Table of Contents Assets and liabilities of the Company’s Canadian and Mexican operations are translated from their functional currency to U.S. dollars using exchange rates in effect at the balance sheet date and revenue and expense accounts are translated at average monthly exchange rates during the period. Adjustments resulting from the translation process are included in accumulated other comprehensive income. Transactional gains and losses arising from receivable and payable balances, including intercompany balances, in the normal course of business that are denominated in a currency other than the functional currency of the operation are recorded in the statements of income when they occur. The assets held at the Company’s Canadian and Mexican subsidiaries at June 27, 2026 were collectively, as translated to U.S. dollars, less than 2% of total consolidated assets. Accordingly, translation gains or losses of 55% or less related to the Canadian and Mexican operations would not be material.
