Interest Rate Sensitivity Risk The principal objectives of our investment activities are to preserve principal, provide liquidity, and maximize income consistent with minimizing risk of material loss. We are exposed to market risk related to changes in interest rates. We may choose based on our investment strategy to hold cash, cash equivalents, and investments in interest-bearing or non-interest-bearing accounts. Based upon a sensitivity model, an immediate hypothetical 50-basis point change in interest rates on interest-bearing balances at June 30, 2026, would have resulted in a $0.2 million impact on our investment income included in net income for the three months ended June 30, 2026. We do not enter into investments for trading or speculative purposes. We did not have any variable interest rate outstanding debt as of June 30, 2026. SPS COMMERCE, INC. 30 Form 10-Q for the Quarterly Period ended June 30, 2026 Table of Contents Foreign Currency Exchange Risk Due to international operations, we have revenue, expenses, assets, and liabilities that are denominated in currencies other than the U.S. dollar, primarily the Australian dollar, Canadian dollar, and Euro. Our consolidated balance sheet, results of operations, and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign exchange rates. Our predominate exposure to foreign currency exchange rate fluctuations is due to non-monetary assets held in currencies other than the U.S. dollar, and thus fluctuations in foreign currencies primarily result in comprehensive income (loss), not net income (loss). Our sales are primarily denominated in U.S. dollars. Our expenses are generally denominated in the local currencies in which our operations are located. As of June 30, 2026, we maintained 8% of our total cash and cash equivalents in foreign currencies. Based upon a sensitivity model, an immediate hypothetical 10% unfavorable change in all foreign currency exchange rates would have resulted in a $1.4 million impact on our cash and cash equivalents held in currencies other than the U.S. dollar as of June 30, 2026. We have not used any forward contracts or currency borrowings to hedge our exposure to foreign currency exchange risk, although we may do so in the future. During the three and six months ended June 30, 2026, inflation and changing prices have not had a material effect on our business and we do not expect that inflation or changing prices will materially affect our business in the foreseeable future.
