For the Company's ADS holders, the ADS Ratio Change will have the same effect as a one-for-thirty 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 or about July 6, 2026, U.S. Eastern Time (the "Effective Date"), subject to the effectiveness of the post-effective amendment to the Registration Statement on Form F-6 on or before that date.

On the Effective Date, holders of ADSs in the Direct Registration System ("DRS") and in The Depository Trust Company ("DTC") will have their ADSs automatically exchanged and need not take any action. The exchange of every thirty (30) then-held (existing) ADSs for one (1) new ADS will occur automatically on the Effective Date, with the then-held ADSs being cancelled and new ADSs being issued by the depositary bank. Citibank, N.A., as the depositary bank for the Company's ADS program, will arrange for the exchange. The Company's ADSs will continue to be traded on the Nasdaq Stock Market under the ticker symbol "NIPG."
