Vietnam Steel Q3 2026 Earnings: TIS, TDS, TNS Swing to Profit

Three Vietnamese steel companies reported sharply improved Q3 2026 earnings, led by Gang thép Thái Nguyên (TISCO, ticker TIS) swinging back to profit after a year-earlier loss.

What Happened

Gang thép Thái Nguyên (TISCO, ticker TIS) released consolidated Q3 2026 financial statements showing net revenue of VND 3,842B, up more than 39% year-on-year. Cost of goods sold rose to VND 3,717B, but gross profit still climbed nearly 85% to VND 125B, pushing gross margin to 3.26% from 2.45%. Financial expenses rose almost 25% to VND 34B, mostly interest costs of VND 33B, while selling and administrative expenses increased 45% and 35% respectively. TISCO nonetheless reported after-tax profit of VND 4B, reversing a VND 12B loss in the same quarter last year. For the first nine months of 2026, revenue reached VND 10,744B (+19.5%) and net profit VND 28B, versus a VND 7B loss a year earlier.

Thép Thủ Đức – VNSTEEL (TDS) reported Q3 2026 net revenue of VND 670B, up 1% year-on-year, while cost of goods sold fell more than 1% to VND 648B. Gross profit rose 65% to VND 22B, lifting gross margin to 3.3% from about 2%. Financial expenses jumped from VND 66M to VND 3B on higher interest costs, and other profit fell sharply from VND 3.6B to VND 84M.

Thép Tấm lá Thống Nhất (TNS) reported Q3 profit 10 times the year-earlier level, according to its filing.

Market Context

All three tickers are small-cap steel names trading on the UPCOM exchange, where liquidity is thinner and price discovery is less efficient than on HOSE or HNX. TIS closed at VND 4,500, TDS at VND 8,000 and TNS at VND 3,400 on 16 October 2026, all at low absolute price levels that reflect the sector’s multi-year downturn. The Q3 results mark a second consecutive quarter of margin recovery for several producers, consistent with stabilizing domestic construction demand and lower input cost pressure. The broader Vietnamese steel sector has been recovering from the 2022-2023 trough, though profitability remains thin relative to historical peaks.

Strategic Significance

The key takeaway for long-term investors is that margin recovery is now visible across the small-cap tier of Vietnam’s steel sector, not just at the largest producers. TISCO’s swing to profit on 39% revenue growth shows operating leverage is returning as volumes recover, while TDS’s 65% gross profit increase on flat revenue demonstrates that cost normalization, not just demand, is driving earnings. For TNS, the 10-fold profit jump off a low base signals that even marginal producers are benefiting. The strategic question is whether this reflects a durable demand recovery in construction and infrastructure, or a one-off cost tailwind. The thin absolute margins (3.26% at TIS, 3.3% at TDS) leave little buffer if input costs rise again.

What to Watch

• Q4 2026 earnings releases from TIS, TDS and TNS, expected in January 2027, to confirm whether margin expansion is sustained.
• Domestic steel price trends and input cost data, particularly iron ore and coking coal, which drive gross margins.
• Vietnam construction and infrastructure investment data, including public disbursement figures, as a demand indicator.
• Any foreign-ownership or liquidity filings on UPCOM for these tickers, given their small free float.
• Full-year 2026 guidance updates from VNSTEEL group companies, which could signal sector-wide outlook.
