What Happened
According to a filing from CTCP Mía đường Cao Bằng (CBS), chairman Nông Văn Sơn and his sister Nông Thị Thu Hà have registered to sell a combined 50.66% stake to Nasu, a subsidiary of TH Group. The sales are scheduled between 11/8 and 28/8/2026, using negotiated transactions.

Chairman Sơn stated that Nasu, one of Vietnam’s largest sugar mills, has substantial resources that can help resolve the competition for raw sugarcane.

Market Context
CBS trades on UPCOM, with a closing price of VND 23,000 on 11/8/2026, implying a market cap of VND 121 billion. The sugar sector in Vietnam faces intense competition for raw materials, especially from Chinese mills across the border, which have consolidated and increased processing capacity, leading to a 30-40% shortage in sugarcane supply. CBS’s main markets are northern provinces including Bắc Ninh, Bắc Giang, Lạng Sơn, Hà Nội, and others.
Strategic Significance
This stake sale to Nasu, part of TH Group, is strategically significant as it aligns CBS with a larger ecosystem that includes dairy production, which requires sugar as an input. The synergies extend to molasses for cattle feed and cow manure for fertilizing sugarcane fields. This vertical integration could stabilize CBS’s raw material supply and improve operational efficiency. For investors, the deal brings a strong strategic partner with financial resources, potentially enhancing CBS’s long-term competitiveness.
What to Watch
- Completion of the share transfers by 28/8/2026 as registered.
- Any adjustments to the transfer plan, such as reducing the stake to 36% or splitting into multiple tranches.
- CBS’s operational performance in the upcoming quarters, particularly raw material supply and production volumes.
- Integration progress with Nasu and TH Group, including any management or operational changes.
- Regulatory approvals and any further disclosures related to the transaction.
