Nam Viet CEO's son buys 1M ANV shares as stock drops 40% YTD

Overview

Doãn Chí Thiên, Phó Tổng giám đốc of CTCP Nam Việt (Navico, HOSE: ANV), has completed his third purchase of 1 million ANV shares this year, raising his stake to 1.18% from 0.8%. The transactions occurred as ANV’s share price fell nearly 40% year-to-date, even as the company reported a sharp drop in Q2 profit.

Key Facts

• Doãn Chí Thiên bought 1 million ANV shares between July 28 and August 11, 2026, increasing his holding from 0.8% to 1.18% of charter capital.
• This is his third 1-million-share purchase in 2026; earlier buys were in March and April.
• At an estimated average price of 17,000 VND/share, the transaction cost approximately 17 billion VND.
• ANV closed at 17,850 VND on August 13, 2026, down 39% from February 4, 2026.
• Q2 2026 revenue reached 1,937 billion VND, up 12.2% year-on-year, but net profit fell 59.5% to nearly 135 billion VND.
• Gross margin contracted to 16.1% from 28.2% in Q2 2025, reducing gross profit by 35.9% to about 312 billion VND.

What Happened

Doãn Chí Thiên, son of Nam Viet’s CEO Doãn Tới, has been steadily accumulating ANV shares throughout 2026. His latest purchase of 1 million shares, completed between July 28 and August 11, brings his total stake to 1.18%. The company disclosed the transaction in a regulatory filing, noting that his father, Doãn Tới, remains the largest shareholder with 54.98% (over 146.6 million shares).

The buying spree comes amid a significant share price decline. ANV fell to around 16,000 VND at the time of the registration, and by August 13 it traded at 17,850 VND, down 39% from its February peak. Despite the insider buying, the company’s fundamentals have weakened: Q2 net profit dropped 59.5% year-on-year, primarily due to a sharp contraction in gross margin from 28.2% to 16.1%. Revenue growth of 12.2% was offset by higher cost of goods sold and a 24.8% increase in selling and administrative expenses.

Market Context

ANV, listed on HOSE, has been under pressure in 2026, with the stock losing nearly 40% of its value since early February. The aquaculture sector has faced margin headwinds, and Nam Viet’s Q2 results reflect this, with net profit falling despite revenue growth. The insider purchases by Doãn Chí Thiên may signal confidence, but the market has yet to respond positively, as the stock remains near its recent lows. The broader Vietnamese market has shown mixed trends, with investors focusing on earnings quality and margin sustainability.

Strategic Significance

Nam Viet’s strategic pivot to tilapia farming, including converting 600 hectares to tilapia production to raise capacity to 1,000 tons per day, is a long-term growth driver. However, the current margin squeeze suggests near-term challenges in input costs or pricing. The insider buying by the CEO’s son could be interpreted as a signal of management’s belief in the company’s recovery, but investors should weigh this against the deteriorating profitability. The company’s 2026 target of 1,070 billion VND net profit appears ambitious given H1 performance, which may require a strong H2 rebound.

What to Watch

• Q3 2026 earnings release (expected October 2026) to see if margin recovery materializes.
• Further insider transactions by Doãn Chí Thiên or other executives.
• Tilapia output and selling prices, especially in export markets.
• Any updates on the 600-hectare conversion and capacity expansion timeline.
• Movement in ANV’s share price relative to the 16,000 VND support level seen in August.
