Hong Kong’s Securities and Futures Commission (SFC) issued a High Concentration of Shareholding notice on 27 March 2026, highlighting that 25 shareholders collectively controlled 484.83 million shares of IDT International Limited, equal to 93.24% of the company’s 519.98 million issued shares as at 16 March 2026. Only 35.16 million shares, or 6.76%, remained in public hands.

The regulator noted that IDT International’s share price climbed 989.9%, jumping from HK$0.79 on 10 September 2025 to HK$8.61 on 16 March 2026. After the announcement window, the stock closed at HK$5.60 on 26 March 2026, still 608.9% above its 10 September 2025 level.

Given the limited free float and sizeable price volatility, the SFC cautioned current shareholders and potential investors that even small trades could trigger significant price fluctuations and urged “extreme caution” when dealing in the shares.
