Analysis date
Published
MW GOBLIN · AI company research
Conditionally positive as of 2026-09-30. Growth in module sales and improved profitability have been confirmed, but it is difficult to conclude that the shares are undervalued at KRW 13,620. The key questions are the sustainability of operating profit excluding convertible bond valuation gains and losses, and improvement in cash flow after investment.

Higher module sales and improved profitability
The company has established a supply base for SOFC plumbing modules, and expansion in module sales has also been confirmed. Module sales in the first half of 2026 were KRW 6.60 billion, exceeding the KRW 4.41 billion for all of 2025, while the company-wide operating margin rose to 25.7% from 15.2% in the same period a year earlier, supporting profit growth. However, there is no disclosed basis for treating all module sales as SOFC sales, and product-level profit margins have not been disclosed, so the improvement in profitability cannot be attributed to fuel cells alone. [1][2]
Cash conversion matters more than accounting losses
The increase in earnings has not generated enough funding for investment. Subtracting KRW 15.56 billion of purchases of property, plant and equipment and intangible assets from first-half 2026 operating cash flow of KRW 5.42 billion leaves cash flow of -KRW 10.14 billion. KRW 9.91 billion was tied up by increases in accounts receivable and inventory. The net loss of KRW 3.09 billion was affected by a non-cash net derivative valuation loss of KRW 11.25 billion; apart from the extinguishment of the convertible bond balance, recovery of working capital is the next test for shareholder value. [1]
Reference multiple of 17.2x using historical financial figures
EV/operating profit is used to avoid distortion from derivative gains and losses. The reference multiple is 17.2x, using a share price of KRW 13,620, 19,247,670 shares as of the end of July 2026, and net debt including leases of KRW 33.59 billion as of the end of June. This is not a definitive current EV. The denominator is operating profit of KRW 17.22 billion for the 12 months through June, calculated as 2025 + the current half-year − the prior half-year. A target price is withheld because the individual-order structure limits long-term visibility into module growth and margins. [1][2][3]
What could change the thesis
- Condition for an upgrade: if higher module sales and maintained margins are both confirmed in the second half, and operating cash flow covers capital expenditures, growth will be assessed as contributing more strongly to shareholder value.
- Condition for a downgrade: if slower customer orders reduce module sales and margins, or if accounts receivable and inventory burdens increase net debt, the sustainability of earnings and the valuation will be marked down.
