For the Company's ADS holders, the ADS Ratio Change will have the same effect as a one-for-25 reverse ADS split. A post-effective amendment to the Registration Statement on Form F-6 will be filed with the U.S. Securities and Exchange Commission to reflect the ADS Ratio Change. The Company anticipates that the ADS Ratio Change will be effective on June 25, 2026, U.S. Eastern Time (the "Effective Date").

Each ADS holder of record at the close of business on the Effective Date will be required to surrender and exchange every 25 existing ADSs then held for one new ADS. Deutsche Bank Trust Company Americas, as the depositary bank for the Company's ADS program, will arrange for the exchange of the current ADSs for the new ones. The Company's ADSs will continue to be traded on the Nasdaq Stock Market under the ticker symbol "NAMI."
