Recent Enforcement Action by the State Securities Commission of Vietnam (SSC)

On August 13, 2025, the State Securities Commission of Vietnam (SSC) issued Decision No. 195/QD-XPHC, imposing administrative sanctions for violations in the securities and stock market field against TST Joint Stock Company (UPCoM: TST), a technical telecommunications services provider. The company is headquartered at 51B, Alley 40 To Vinh Dien Street, Khuong Dinh Ward, Hanoi.

Specifically, TST was fined VND 85 million for failing to disclose information as required by law. The company did not publish on the disclosure system of the State Securities Commission and the Hanoi Stock Exchange (HNX) documents such as its audited separate and consolidated financial statements for 2024, the 2024 corporate governance report, the 2024 annual report, and the resolutions of the 2025 Annual General Meeting of Shareholders.

Additionally, TST was fined VND 15 million for failing to develop and submit for approval by the General Meeting of Shareholders the internal regulations on corporate governance, the regulations on the activities of the Board of Directors, and the Supervisory Board.

In total, TST was fined VND 100 million for the above-mentioned violations.

In the stock market, TST shares closed the trading session on August 15 at VND 10,300 per share, unchanged from the previous session, with a matched volume of 8,500 units.

Despite TST shares being restricted from trading and under warning status, their market price has surged by more than 80% in the last two months. The company’s market capitalization has increased significantly to over VND 49.4 billion.

In a related development, TST shares were recently placed under warning status from August 14 due to the company’s failure to hold the 2025 Annual General Meeting of Shareholders within the prescribed time limit.

The HNX also announced the maintenance of trading restrictions on TST shares due to the issuance of a disclaimer of opinion on the 2023 audited financial statements and the late submission of the 2024 audited financial statements by more than 45 days compared to the prescribed deadline.
