EO Technics: Sharp Profit Recovery and a 98.8% One-Year Share Price Gain Lift Multiples

Thesis

The data supports a clear earnings recovery. Trailing twelve-month (TTM) operating income to H1 2026 is ₩109.3B, versus ₩31.2B in 2024 and ₩80.8B in 2025. The operating margin has risen to 24.6% from 9.7% in 2024, above the 20.0% to 20.8% seen in 2021 and 2022.

The share price has moved faster than the numbers. It is up 14.7% in one month, 42.1% in three months and 98.8% in one year, and sits about 18.0% below the 52-week high of ₩623,000 and well above the low of ₩219,000. Valuation multiples are high, so the market is pricing in continued strength. The data does not show the reasons for the share price move, because no news headlines were provided.

Investor flow, foreign ownership and short balance data are not available, so we cannot say who has been buying.

Business overview

EO Technics is listed on KOSDAQ (code 039030) and classified in the Machinery sector. It was founded on 1993-12-30 and listed on 2000-08-24. It has 12,319,550 listed shares and is led by co-CEOs 성규동 and 박종구. The data does not describe its products or customers.

Revenue was ₩390.9B in 2021 and ₩447.2B in 2022, fell 29.2% in 2023 to ₩316.4B, then recovered to ₩320.9B in 2024 and ₩380.9B in 2025. TTM revenue to H1 2026 is ₩444.7B, close to the 2022 peak. The history shows a cyclical pattern.

Financial analysis

All figures come from filed financial statements (DART).

Revenue grew 1.4% in 2024 and 18.7% in 2025. TTM revenue is ₩444.7B. Operating income was ₩28.3B in 2023, ₩31.2B in 2024, ₩80.8B in 2025 and ₩109.3B TTM. Net income was ₩57.2B in 2025 and ₩108.5B TTM, a net margin of 24.4%.

Return on equity (ROE) was 6.7% in 2023, 7.4% in 2024 and 8.9% in 2025, and is 16.1% TTM, similar to 15.1% in 2022. TTM net income is almost equal to operating income, which suggests non-operating items such as financial income or tax effects contribute; the data does not give the breakdown.

The balance sheet is conservative. Liabilities to equity is 11.1%, cash is ₩233.1B and borrowings are ₩7.0B. TTM free cash flow is ₩74.9B, about 69.0% of TTM net income.

Valuation

At ₩511,000 the stock trades at a P/E of 58.0, P/B of 8.4 and P/S of 14.2. The dividend yield is 0.2%. Enterprise value is about ₩6.07T; EV/EBITDA is not available.

The year-end 2025 P/E was 58.6 and P/B was 4.9, so the P/E is similar but P/B has risen as the share price gained. Earlier year-end multiples are not available.

Among the peers provided, P/E ranges from 37.1 (Wonik IPS) to 4,456.7 (Rainbow Robotics), with Doosan Enerbility at 252.9, Hanmi Semiconductor at 106.7 and Jusung Engineering at 1,650.0. EO Technics' P/E is below all peers except Wonik IPS. Its P/B of 8.4 is above Wonik IPS (6.0) and Doosan Enerbility (5.6), and below Hanmi Semiconductor (31.7), Jusung Engineering (20.2) and Rainbow Robotics (57.1). The peer set is mixed and may not be a close match.

Catalysts

• The half-year report for June 2026, filed 2026-08-14, shows TTM operating income of ₩109.3B, and the next quarterly report will show whether the margin holds.
• A corporate value-up plan was filed on 2026-04-01, which may be relevant for shareholder returns, though its details are not in the data.
• Repeated 5%+ holding reports (most recently 2026-10-07, plus 2026-09-01, 2026-08-03 and 2026-07-06) show ongoing changes in large shareholders' positions.
• Annual general meeting results and an independent director filing on 2026-03-31 relate to governance.

Risks

• The P/E of 58.0 and P/B of 8.4 leave the stock sensitive to any slowdown in earnings growth.
• Revenue fell 29.2% in 2023, showing that results can be cyclical.
• The share price is up 98.8% in one year and 42.1% in three months, so it may be volatile after such a rapid move.
• The dividend yield is only 0.2%, so returns rely mostly on share price changes.
• Flow, foreign ownership, short balance and news data are not available, so some market signals cannot be assessed.

Closing view

The filed numbers show a strong recovery: margins of 24.6%, ROE of 16.1%, a net cash position and positive free cash flow. The market has already priced much of this in, with the share price almost doubling in a year and multiples that are high in absolute terms, though mixed against peers. The evidence supports a business in an upswing but leaves open how long it lasts, and the missing flow and news data limit the view of market sentiment.
