Hanoimilk (HNM) Insider Swap: CFO to Sell 23.48% Stake as Auditor Buys

Overview

Hanoimilk (ticker HNM, UPCOM) disclosed that Chief Accountant Pham Tung Lam registered to sell 10 million shares, equal to 23.48% of the company’s charter capital, while Head of the Supervisory Board Dao Bich Thuy registered to buy exactly 10 million shares. The paired filings move close to a quarter of HNM’s 44.4 million outstanding shares between two sitting executives, and they arrive alongside H1 2026 results showing revenue growth of 3% but a profit decline of more than 11%.

Key Facts

• Pham Tung Lam, Chief Accountant, registered to sell 10 million HNM shares, equivalent to 23.48% of charter capital, for personal financial needs.
• Before the transaction, Lam held 10.43 million shares (23.48%); a full sale would leave him 425,000 shares, or roughly 0.96%.
• Dao Bich Thuy, Head of the Supervisory Board, registered to buy 10 million HNM shares and currently holds none; completion would give her about 22.52% of the company.
• Lam’s sale window runs 21 September to 20 October 2026; Thuy’s purchase window runs 18 September to 16 October 2026, both via put-through and order matching.
• Hanoimilk has 44.4 million shares outstanding, so the two filings cover close to one quarter of charter capital.
• H1 2026 net revenue reached more than VND 385 billion, up 3% year on year, while net profit fell more than 11% to nearly VND 11.6 billion.
• HNM closed at VND 8,300 on 21 September 2026.

What Happened

The filings, published via the company’s disclosure channel, state that Pham Tung Lam registered to sell 10 million HNM shares to meet personal financial needs. His pre-transaction holding of 10.43 million shares equals 23.48% of Hanoimilk’s charter capital; if the full registered volume is sold, his residual stake falls to 425,000 shares, about 0.96%. The sale is scheduled for 21 September to 20 October 2026 using put-through and order-matching methods.

In a near-identical filing, Dao Bich Thuy, Head of the Supervisory Board, registered to buy 10 million HNM shares for investment purposes, from 18 September to 16 October 2026, also via put-through and order matching. She currently holds no HNM shares; a completed purchase would leave her with 10 million shares, or approximately 22.52% of the company. The article notes this is not the first large transfer between the two executives: on 23 June 2026 Thuy sold her entire 10 million shares while Lam bought exactly 10 million, and on 21 April 2026 Lam sold 8 million shares on the same day Thuy bought 8 million. In January 2026 Lam bought 8 million and Thuy 2 million, with the seller being Ha Phuong Thao, daughter of Chairman Ha Quang Tuan, who sold 10 million shares.

Market Context

HNM trades on UPCOM, Vietnam’s unlisted public company market, and closed at VND 8,300 on 21 September 2026, the same day Lam’s sale registration was reported. The stock sits in the Consumer Staples sector, where Hanoimilk competes with larger listed dairy names such as Vinamilk and Moc Chau. The recurring pattern of matched buy-sell registrations between the same two executives, rather than open-market accumulation or distribution, is the defining feature of HNM’s ownership record since at least May 2025, when Chairman Ha Quang Tuan sold 10 million shares on the same day his daughter Ha Phuong Thao bought 10 million.

Strategic Significance

For long-term investors, the signal is ownership structure rather than operating momentum. A 23.48% block changing hands between a chief accountant and a supervisory board head, with no change in the total share count, does not alter Hanoimilk’s fundamentals, but it does concentrate influence in the hands of insiders who have repeatedly swapped the same block. The H1 2026 numbers, revenue up 3% to VND 385 billion while net profit fell more than 11% to VND 11.6 billion, point to margin pressure in a competitive dairy market, so the equity story rests on whether the company can convert modest top-line growth into profit. Until that improves, the share register, not the income statement, is likely to drive HNM’s price discovery.

What to Watch

• Disclosure of whether Lam’s full 10 million-share sale and Thuy’s matching purchase are completed within the 21 September to 20 October 2026 window.
• The resulting ownership percentages and any change to the structure of HNM’s board or supervisory board.
• Q3 2026 results, which will show whether the H1 net profit decline of more than 11% continues or reverses.
• Any further filings by Chairman Ha Quang Tuan or his daughter Ha Phuong Thao, whose January 2026 transfer preceded the current pattern.
• Trading volume and price behaviour on UPCOM around the VND 8,300 close of 21 September 2026 as the transfer window opens.
