Viet Nam Securities Depository and Clearing Corporation (VSDC) would like to announce the record date of corporate action processing for the Securities registering institution as follows:

+ ISIN code: VNMIRVTP2618
(Effective date of code allocation: 15/04/2026; effective date of code cancellation: 13/05/2026)   
+ Planned quantity of issued shares: 51,148,878 shares
+ Issue price: 10,000 VND/share
+ Execution rate: 100:42 (Shareholders are entitled to 1 right for each share they own and to buy 42 new shares for every 100 rights);
- Principle of rounding, handling the fractional shares and unsubscribed shares (if any):
+ Principle of Rounding: Shares issuance for existing shareholders will be rounded down to the whole number;
+ The number of additional shares offered to existing shareholders will be rounded down to the whole number; the fractional shares (if any) will be aggregated and processed according to the method for handling fractional shares outlined below;
+ Any surplus shares resulting from rounding (fractional shares) and any remaining shares not subscribed by shareholders will be distributed by the Board of Directors to other parties (including shareholders of the Corporation who wish to increase their shareholding) as authorized by the General Meeting with the selling price not lower than that offered to existing shareholders and comply with prevailing laws.
+ In the case that the share distribution period expires as prescribed by  prevailing laws (including any extension period (if any)), if there are still undistributed shares, the Board of Directors shall decide to terminate the offering.
- Example: On the record date, shareholder A owns 125 shares. Therefore, shareholder A will be entitled to purchase the corresponding number of new shares: 125/100*42= 52.5 shares. According to the rounding principle, the number of shares shareholder A is entitled to purchase is 52 shares. The 0.5 fractional shares will be aggregated and processed according to the method for handling excess shares due to rounding (fractional shares).
