Credit Risk See also Note 4 to the condensed consolidated financial statements, “Financial Instruments with Off-Balance Sheet Risk and Concentrations of Credit Risk”. 68 Market Risk We conduct our market-making and trading activities predominantly as a principal, which subjects our capital to significant risks. These risks include, but are not limited to, absolute and relative price movements, price volatility and changes in liquidity, over which we have virtually no control. Our exposure to market risk varies in accordance with the volume of client-driven market-making transactions, the size of the proprietary positions and the volatility of the financial instruments traded. We seek to mitigate exposure to market risk by utilizing a variety of qualitative and quantitative techniques: •Diversification of business activities and instruments; •Limitations on positions; •Allocation of capital and limits based on estimated weighted risks; and •Daily monitoring of positions and mark-to-market profitability. We utilize derivative products in a trading capacity as a dealer to satisfy client needs and mitigate risk. We manage risks from both derivatives and non-derivative cash instruments on a consolidated basis. The risks of derivatives should not be viewed in isolation, but in aggregate with our other trading activities. We are exposed to market risk in connection with our retail trading activities. Because we act as counterparty to our self-directed/retail clients’ transactions, we are exposed to risk on each trade that the value of our position will decline. Accordingly, accurate and efficient management of our net exposure is a high priority, and we have developed policies addressing both our automated and manual procedures to manage our exposure. These risk-management policies and procedures are established and reviewed regularly by the Risk Committee of our Board of Directors. Our risk-management policies require quantitative analyses by instrument, as well as assessment of a range of market inputs, including trade size, dealing rate, client margin and market liquidity. Our risk-management procedures require our team of senior traders to monitor risk exposure and update senior management both informally over the course of the trading day and formally through intraday and end of day reporting. A key component of our approach to managing market risk is that we do not initiate market positions for our own account in anticipation of future movements in the relative prices of products we offer. 69 Management believes that the volatility of revenues is a key indicator of the effectiveness of our risk management techniques. The graph below summarizes volatility of our daily revenue, determined on a marked-to-market basis, during the nine months ended June 30, 2026. The graph above includes unrealized price movements in our precious metals inventories and related futures hedge positions during the period in which we experienced temporary dislocations in published London spot market cash prices and Comex listed gold and silver futures contracts, related to potential tariffs to be imposed by the U.S. government on imported metals. In our securities market-making and trading activities, we maintain inventories of equity and debt securities. In our Commercial segment, our positions include physical commodities inventories, precious metals on lease, forwards, futures and options on futures, and OTC derivatives. Our commodity trading activities are managed as one consolidated book for each commodity encompassing both cash positions and derivative instruments. We monitor the aggregate position for each commodity in equivalent physical ounces, metric tons, or other relevant unit. Interest Rate Risk In the ordinary course of our operations, we have interest rate risk from the possibility that changes in interest rates will affect the values of financial instruments and impact interest income earned. Within our domestic institutional dealer in fixed income securities business, we maintain a significant amount of trading assets and liabilities which are sensitive to changes in interest rates. These trading activities primarily consist of securities trading in connection with U.S. Treasury, U.S. government agency, agency mortgage-backed and agency asset-backed obligations, as well as investment grade, high-yield, convertible and emerging markets debt securities. Derivative instruments, which consist of futures, TBA securities and forward settling transactions, are used to manage risk exposures in the trading inventory. We enter into TBA securities transactions for the sole purpose of managing risk associated with mortgage-backed securities. In addition, we generate interest income from the positive spread earned on client deposits. We typically invest in U.S. Treasury bills, notes, and obligations issued by government sponsored entities, reverse repurchase agreements involving U.S. Treasury bills and government obligations or AA-rated money market funds. In some instances, we maintain interest earning cash 70 deposits with banks, clearing organizations and counterparties. We have an investment policy which establishes acceptable standards of credit quality and limits the amount of funds that can be invested within a particular fund, institution, clearing organization or counterparty. We estimate that as of June 30, 2026, an immediate 25 basis point decrease in short-term interest rates would result in approximately $11.7 million less in annual net income. We manage interest expense using a combination of variable and fixed rate debt. The debt instruments are carried at their unpaid principal balance which approximates fair value. As of June 30, 2026, $660.7 million of outstanding principal debt was variable-rate debt. We are subject to earnings and liquidity risks for changes in the interest rate on this debt. As of June 30, 2026, $1,174.9 million of outstanding principal debt was fixed-rate long-term debt. Foreign Currency Risk Currency risk arises from the possibility that fluctuations in foreign exchange rates will impact the value of our earnings and assets. Entities that have assets and liabilities denominated in currencies other than the primary economic environment in which the entity operates are subject to remeasurement. Principally, all sales are denominated in the currency of the subsidiary, while related operating costs are denominated in the currency of the local country and translated into USD for consolidated reporting purposes. Although the majority of the assets and liabilities of these subsidiaries are denominated in the functional currency of the subsidiary, they may also hold assets or liabilities denominated in other currencies. As a result, our results of operations and financial position are exposed to changing currency rates. We have executed hedging transactions in relation to certain currencies to mitigate our exposure to volatility in certain foreign currency exchange rates. From time-to-time, we may consider entering into larger hedges in certain contracts or hedging transactions in additional currencies to mitigate our exposure to more foreign currency exchange rates. These hedging transactions may not be successful.
