Overview
Kosy Group (ticker KOS, HOSE) disclosed that Chairman Nguyen Viet Cuong and related entity Cong ty TNHH Dau tu Dia oc Kosy sold KOS shares, with the affiliate’s holding easing from 4.62% to 4.61% after a forced-sale shortfall. The insider sales landed as KOS shares fell limit-down for five consecutive sessions from 21 to 25 September 2026, a slide the company attributes to margin cuts and thin market liquidity rather than internal operations.
Key Facts
- Dau tu Dia oc Kosy registered to sell 250,000 KOS shares between 24 September and 30 September 2026, but completed only 22,300 shares via order matching.
- The shortfall was attributed to forced selling (ban giai chap); the affiliate’s stake fell from 10 million shares (4.62%) to nearly 9.98 million shares (4.61%).
- Chairman Nguyen Viet Cuong sold more than 4.26 million KOS shares between 27 August and 24 September 2026, out of 5 million registered, citing unfavorable market conditions.
- Following that transaction, Cuong holds nearly 72.38 million KOS shares, equal to 33.43% of charter capital.
- Vice Chairwoman Nguyen Thi Hang holds nearly 13.9 million KOS shares, or 6.42% of charter capital.
- KOS fell limit-down for five straight sessions from 21 September to 25 September 2026, with the close at VND 16,950 on 30 September 2026.
- Kosy Group said several securities firms cut margin ratios for KOS, adding selling pressure on the stock.
What Happened
In a report filed with the State Securities Commission of Vietnam (UBCKNN), the Ho Chi Minh City Stock Exchange (HoSE) and Kosy Group, Dau tu Dia oc Kosy disclosed a registered sale of 250,000 KOS shares from 24 to 30 September 2026. Only 22,300 shares were matched, with the company citing forced selling as the reason the full order was not completed. The affiliate’s holding moved from 10 million shares, or 4.62%, to just under 9.98 million shares, or 4.61%.
The filing also details the relationship between the parties: Chairman Nguyen Viet Cuong serves as chairman of Dau tu Dia oc Kosy, while Vice Chairwoman Nguyen Thi Hang is a capital contributor to the same entity. Separately, Kosy Group submitted an explanation to UBCKNN and HoSE regarding the five-session limit-down run, pointing to broad market declines, weaker liquidity, financing difficulties for operations, and margin reductions by brokers on KOS. The company said its core businesses in real estate development, renewable energy and project operations are proceeding as planned with no unusual internal developments.
Market Context
KOS trades on HOSE and closed at VND 16,950 on 30 September 2026 after the five-session floor streak. The selling pressure reflects a combination of insider disposals, forced liquidation at a related entity and broker margin tightening, set against a Vietnamese equity market the company describes as declining on inertia with shrinking liquidity. Real estate remains a capital-intensive sector where access to credit and project funding drives sentiment, and KOS is exposed to both property development and renewable energy execution.
Strategic Significance
The chairman’s stake of 33.43% keeps control firmly in place, so the sales read more as liquidity management by insiders than a change in the ownership structure. The more consequential signal is the forced-sale mechanism at the affiliate and the margin cuts by brokers, which suggest counterparties are re-rating the collateral and risk profile of KOS. For long-term holders, the thesis rests on whether the company’s real estate and renewable energy pipeline can be funded without further equity or collateral stress, and whether the insider selling reflects personal liquidity needs or a broader read on valuation.
