Wooyang HC: Plant Equipment Turnaround and Hantech Comparison
A review of plant equipment recovery, financial rebuilding, and the profitability gap versus Hantech.
0. Bottom line first
I view Wooyang HC as a recovery play in traditional plant equipment, not yet as a company that has proven the high-margin growth mix seen at Hantech. For 2025 3Q cumulative results, Wooyang posted KRW 77.4 billion revenue, KRW 4.6 billion operating profit, and 5.9% OPM; Hantech posted KRW 124.1 billion revenue, KRW 29.1 billion operating profit, and 23.5% OPM.
1. Rebuilding history
Official fact: The source says Wooyang HC began as Wooyang Industrial in 1993, incorporated in 1996, obtained ASME S and U Stamps in 2002, moved to Pyeongtaek Poseung Industrial Complex in 2004, and signed a Helixchanger® technology partnership with ABB Lummus in 2009.
Official fact: The company filed for rehabilitation in March 2015, completed restructuring, and exited rehabilitation in 2018. As of 2025 3Q, its largest shareholder is Soulbrain Holdings with a 38.71% stake.
Interpretation: This is not a pure high-growth story. It is a normalization story built on recovered fabrication capability and better financial stability. Valuation becomes more convincing when order recovery, margin recovery, and new-business revenue are all visible.
2. Business portfolio
Chemical plants
Heat exchangers, towers, pressure vessels, and reactors for refining and petrochemical processes form the cash-cow base.
Energy plants
Condensers, feed-water heaters, and deaerators for power-plant BOP equipment require thermal-fluid design capability.
Eco/new business
Water treatment, environmental equipment, and CCUS R&D are positioned as future growth options.
Official fact: The source gives 2025 3Q revenue mix of 16.5% for heat exchangers, 11.07% for reactors, 28.86% for towers, and 38.44% for pressure vessels. Towers and pressure vessels together account for 67% of sales.
Interpretation: Wooyang’s edge comes from special-material fabrication, large-scale manufacturing, and a site close to Pyeongtaek Port. The weakness is that ordinary towers and vessels face tougher price competition than Hantech’s cryogenic tanks.
3. Comparison with Hantech
| Item (2025 3Q cum.) | Wooyang HC | Hantech | Note |
|---|---|---|---|
| Revenue | KRW 77.4bn | KRW 124.1bn | Hantech 1.6x |
| Operating profit | KRW 4.6bn | KRW 29.1bn | Hantech 6.3x |
| OPM | 5.9% | 23.5% | Hantech’s high-margin structure |
| Net income | KRW 2.1bn loss | KRW 27.2bn profit | Wooyang affected by one-off merger costs, etc. |
| Total assets | KRW 231.8bn | KRW 223.6bn | Similar scale |
| Total liabilities | KRW 45.4bn | KRW 65.4bn | Wooyang balance sheet improved |
Official fact: The source explains that Hantech has higher exposure to LNG and ammonia storage tanks and cryogenic insulation technology for temperatures such as -162 degrees, while Wooyang is more weighted to ordinary towers and vessels.
Interpretation: Wooyang’s undervaluation case requires separating cyclical recovery from product-mix weakness. Without evidence of high-margin new-business revenue, it remains primarily a recovery investment.
4. Investor checkpoints
- Check whether Middle East petrochemical investment and global EPC backlogs translate into equipment orders.
- Separate 2025 3Q revenue weakness into timing lag versus competitive loss.
- Financial stability improved after Soulbrain Holdings, but 5.9% OPM still signals a limited high-value product mix.
- CCUS, water treatment, LNG conversion, and power-plant upgrade work must become meaningful revenue.
