Donga Plastic Group

What Donga Plastic Group does

Donga Plastic Group is a publicly listed Vietnamese manufacturer of plastic construction fixtures, headquartered in Hanoi and traded on the HOSE exchange under ticker DAG (dag.com.vn). The company was founded in 2001 and operates with 501-1,000 employees. Its core technology is Wood-Plastic Composite (WPC) manufacturing, applied to building materials such as doors and frames intended for interior and exterior decorative and structural uses.

The company's stated product positioning emphasizes WPC doors and frames engineered for compatibility with IoT-based smart-building systems, targeting the smart-building sector as its primary use-case segment via a horizontal go-to-market approach (i.e., the same product family addresses multiple use cases within smart-building projects). Differentiators flagged by management include IoT interoperability and a focus on scaling the supply network and production capacity in response to what it describes as growing smart-building demand. Pricing, distribution channels, named customers, and channel marketing are not disclosed in the available data.

Revenue mechanics are not publicly detailed; the company earns from manufacturing and trading of plastic construction fixtures, with no disclosed pricing model or recurring/subscription component. Financials reported in the data show a sharp 2022→2023 deterioration in revenue, EBITDA, and net income (and a large reported loss in 2023), but the supplied figures are inconsistent with the firm's scale and headcount, suggesting a currency or unit presentation issue that needs reconciliation against the company's audited filings before any of those numbers can be relied on for valuation or trend analysis. No M&A, fundraising, leadership, or partnership transactions are documented in the available data.
