In a recent update, Nguyen The Tai, Chairman of the Board of Directors of HTC Holding JSC (stock code: CET – HNX), has registered to sell his entire stake of 650,000 CET shares, equivalent to a 10% ownership. The transaction is expected to take place from September 25 to October 23 via both agreement and order matching methods.
During the same period and using the same trading methods, two other individuals, Tran Hoang Anh Tuan, Vice Chairman of CET’s Board of Directors, and his father, Tran Hoang Cuong, have also registered to sell their entire holdings of 1.04 million and 0.97 million CET shares, respectively.
Amid this leadership divestment, CET has also experienced changes in its board composition. On September 19, two members of the Board of Directors for the 2023-2028 term, Do Van Dat and Ha Le Thuy Vy, submitted their resignations citing personal reasons.
Notably, the leadership has capitalized on CET’s recent surge, selling shares as the stock hit its highest level in eight years. From a low of VND 4,800 per share in early September, CET’s stock price soared to VND 12,400 per share by September 24, marking a 2.5-fold increase in less than a month.
Alongside the price surge, liquidity has significantly improved. From sessions with only a few hundred shares traded, CET has seen trading volumes reach hundreds of thousands of shares per session.

HTC Holding, originally established in October 2009 as Tech-Vina JSC with an initial capital of VND 3 billion, operates in the production of natural flavor extracts, distilled flavor waters, and wholesale of agricultural and forestry raw materials (excluding wood, bamboo, and rattan) and live animals.
The company’s flagship product, cinnamon essential oil, is produced at its Lao Cai facility. Sourced from over 8,000 cinnamon-growing households across a 5,000-hectare cultivation area, the raw materials are processed into essential oil. As of now, CET’s chartered capital stands at VND 60.5 billion.
CET’s financial performance remains lackluster. In Q2/2025, revenue was recorded at VND 10 billion, a 19% decline year-on-year. The company reported a post-tax loss of VND 75 million due to a sharp increase in raw material costs.
