Dong Son Holdings (DSH) Sets October 26 HOSE Listing as BOT Stake Hits 58%

Overview

Dong Son Holdings (ticker DSH) will hold its first trading session on HOSE on October 26, 2026, moving 35 million shares from UPCoM, where the stock has traded since April 2025. The listing coincides with the company’s shift from pure construction and installation (xây lắp) toward infrastructure investment and asset management, anchored by its December 2025 purchase of a controlling 58% stake in the Hanoi-Bac Giang BOT project. For DSH, the move to HOSE brings a higher-visibility exchange tier and a broader institutional investor base.

Key Facts

• DSH lists 35 million shares on HOSE, with the first trading session set for October 26, 2026.
• The company began trading on UPCoM in April 2025 with 10 million shares, before raising charter capital to VND 350 billion.
• On December 24, 2025, DSH completed the acquisition of more than 16.37 million shares in BOT Hanoi-Bac Giang, lifting its ownership from 25% to 58%.
• The BOT project became a consolidated subsidiary of DSH after the transaction, versus associate accounting previously.
• In 2025, the Hanoi-Bac Giang BOT recorded net revenue of VND 630.88 billion and after-tax profit of VND 216.97 billion, up 6.8% and 26.7% respectively.
• DSH posted 2024 net revenue of more than VND 629 billion, up over 57%, with more than 78% coming from construction.
• DSH was founded in December 2009 as Công ty Cổ phần Đầu tư và Thương mại 319, with Tổng công ty 319 under the Ministry of Defence among its founders.

What Happened

The listing date was disclosed in the company’s announcement of its HOSE admission, as reported in the source article. DSH’s project pipeline includes the Ngọc Hồi bridge and its approach roads, the Hồng Hà bridge on the Vành đai 4 – Vùng Thủ đô ring road, the Tuyên Quang – Hà Giang expressway, the Nam Định – Lạc Quần – coastal road link, and the Sông Đáy overpass connecting Ninh Bình and Nam Định provinces on the Ninh Bình – Nam Định – Thái Bình – Hải Phòng expressway.

The strategic pivot is the BOT stake. By raising its holding in the Hanoi-Bac Giang toll-road operator from 25% to 58% on December 24, 2025, DSH converted an associate investment into a consolidated subsidiary. That changes the revenue model: construction contracts are lumpy and project-dependent, while BOT operations generate recurring cash flow tied to traffic volumes, toll levels and operating costs. The article notes that the effectiveness of this shift will depend on both project execution capacity and the company’s ability to manage its capital base.

Market Context

DSH closed at VND 12,200 on October 15, 2026, according to the price context provided, roughly a week before the scheduled HOSE debut. The stock has traded on UPCoM since April 2025, a venue with thinner liquidity and lighter disclosure requirements than HOSE. The move to HOSE places DSH in the infrastructure and construction segment of the main board, alongside larger listed peers in transport and toll-road development. The article does not disclose the reference price for the first HOSE session, the free-float ratio, or the foreign ownership limit.

Strategic Significance

The thesis for DSH is the conversion of a construction contractor into a mixed model with a recurring toll-road cash engine. Consolidating the Hanoi-Bac Giang BOT at 58% means DSH’s reported revenue and profit now capture the project’s VND 630.88 billion in net revenue and VND 216.97 billion in after-tax profit for 2025, rather than a share of associate income. That gives the group a more stable earnings base to offset the cyclicality of construction contracts, and it positions DSH as an owner-operator of infrastructure assets rather than a contractor bidding for work. The risk is balance-sheet: acquiring an additional 16.37 million BOT shares required capital, and the company’s ability to fund both the acquisition and its construction backlog will determine whether the model delivers.

What to Watch

• Traffic volume and toll-collection data for the Hanoi-Bac Giang route, the key driver of BOT cash flow.
• Progress and disbursement on the Ngọc Hồi, Hồng Hà and Tuyên Quang – Hà Giang projects, and the value of construction work in progress at year-end.
