Our principal financial liabilities consist of trade and other payables, lease liabilities and derivative warrant liabilities. The main purpose of these financial liabilities is to finance our day-to-day operations. Our financial assets consist of prepayments and other receivables and cash, that are derived from our operating activities and funding. We are exposed to market risk, credit risk and liquidity risk. Our senior management oversees the management of these risks. Our Board of Directors (the “Board of Directors”) reviews and approves policies for managing each of these risks, which are summarized below. Market Risk Market risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market prices. Market risk comprises interest rate risk, foreign currency risk and other price risks. Interest Rate Risk We are exposed to interest rate risk primarily through our cash, cash equivalents and marketable securities. Changes in interest rates may cause variations in interest income and expense resulting from short-term interest-bearing assets. We invest in high-quality financial instruments, primarily money market funds and U.S. government and agency securities with maturities of less than one year, which we believe are subject to limited credit risk. We regularly review our investments and monitor the financial markets and we do not currently hedge interest rate exposure. Due to the nature of our investments, we do not believe an immediate 100 basis point change in interest rates would have a material effect on our financial condition. We do not believe that we have any material exposure to interest rate risk or changes in credit ratings arising from our investments. Foreign Currency Risk Foreign currency risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. Our exposure to the risk of changes in foreign exchange rates relates primarily to cash and trade and other payables denominated in currencies other than our functional currency, the U.S. Dollar. As of June 30, 2026, our net exposure to foreign currency risk was $72.6 million, mainly related to the Euro. As of June 30, 2026, the effect of a hypothetical 1% change in exchange rates on currencies denominated in other than our functional currency would result in a potential change in future earnings in our consolidated statement of operations of approximately $0.7 million. 29 We partly manage our foreign currency risk by selectively holding foreign currency in our cash to offset foreign currency exposures from trade and other payables. We plan to use this cash to settle future expenses we expect to incur in those foreign currencies. Other Market Price Risk As a result of the Business Combination, we have derivative warrant liabilities, which are measured at fair value through profit or loss. As of June 30, 2026 the fair value of the derivative warrant liabilities totaled $54.5 million. Prior to 2026, the fair value of the Warrants was determined using the last reported trading price of the Public Warrants which trade under the symbol “NAMSW.” Beginning in 2026, due to a decrease in the trading volume of the Public Warrants, the fair value of the Warrants is determined by utilizing the Black-Scholes option pricing model. The primary driver of the change in fair value of the Warrants derived by such pricing method is the change in the trading price of our Ordinary Shares which trade under the symbol “NAMS.” The value of the derivative warrant liability is directly correlated to the market price of our Ordinary Shares. With all other variables held constant, a 1% change in the market price of our Ordinary Shares would change the value of the derivative warrant liability by approximately 1% or $0.5 million. Credit Risk Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. We are exposed to credit risk primarily from our treasury activities, including deposits with banks and financial institutions and have limited credit risk exposure from our operating activities. We hold available cash in bank accounts with banks which have investment grade credit ratings. Management periodically reviews the creditworthiness of the banks with which it holds assets. We perform research and development activities and do not yet have significant sales. We are able to reclaim VAT, which is recoverable from tax authorities. Management periodically reviews the recoverability of the balance of input value added tax and believes it is fully recoverable.
