POSCO DX: Revenue and Margins Have Fallen From 2023-24 Highs While Valuation Multiples Stay Elevated

Thesis

The data supports a picture of a company whose earnings have shrunk but that still has a clean balance sheet. Revenue fell 27.0% in 2025 and operating margin eased from 7.4% in 2024 to 5.6% in 2025 and 3.5% on a trailing basis as of H1 2026. Trailing ROE is 5.9%, versus 21.1% in 2023. Against this, borrowings are very small, cash is sizable and free cash flow is positive. The high P/E mostly reflects depressed earnings rather than strong profit. The data does not show why revenue declined, nor any company guidance. Investor flows, foreign ownership, short balance and news headlines are not available, so sentiment cannot be assessed from this data.

Financial analysis

All figures come from filed financial statements (DART). Operating income was a loss of ₩19.5B in 2021, then rose to ₩64.7B in 2022, ₩110.6B in 2023 and ₩109.0B in 2024, before falling to ₩60.4B in 2025. Net income followed a similar path: ₩91.9B in 2023, ₩88.0B in 2024, ₩52.1B in 2025. Trailing figures as of H1 2026 are revenue of ₩979.6B, operating income of ₩34.0B (3.5% margin) and net income of ₩32.0B (3.3% margin). Liabilities to equity is 45.1%. Cash is ₩248.3B against borrowings of only ₩76.6M. Trailing free cash flow is ₩49.2B.

Valuation

The stock trades at a P/E of 94.1, P/B of 5.3 and P/S of 3.1, with a dividend yield of 0.6%. Enterprise value is ₩2.76T; EV/EBITDA is not available. At the end of 2025, P/E was 83.9 and P/B 7.7, so P/B has declined while P/E has risen as earnings fell; earlier year-end multiples are not available. Among peers with data, Samsung E&A has a P/E of 13.6 and P/B of 1.8, HD Hyundai Marine Solution 29.6 and 11.1, and KEPCO Engineering & Construction 119.2 and 7.2. POSCO DX's P/E is well above two of the three, and its P/B sits in the middle. SemiFive and Hanyang ENG have no multiples in the data.

Catalysts

• The amended major sales or supply contract filing on 2026-07-28 may bear on future revenue, though the data gives no contract details.
• The H1 2026 half-year report (2026-08-14) and preliminary earnings (2026-07-30) set the current trailing profit base that later results will be compared against.
• On 2026-09-07 filings reported a change in the largest shareholder's holdings, an insider shareholding report and a 5%+ holding report, which investors may watch for ownership shifts.
• An investor relations event on 2026-07-24 shows the company is engaging with the market, though its content is not in the data.

Risks

• Revenue fell 27.0% in 2025 and trailing revenue is lower again, so the decline has not clearly reversed.
• Operating margin has compressed from 7.4% to 3.5% on a trailing basis, leaving less cushion for cost pressure.
• A P/E of 94.1 means the share price depends heavily on earnings recovering, and it is far above Samsung E&A's 13.6.
• The share price fell 10.6% in the past month and is far below its 52-week high, indicating volatility.
• Flow, foreign ownership, short interest and news data are unavailable, so key sentiment signals cannot be checked.

Closing view

The filings show a debt-light company with positive free cash flow, but with earnings and returns far below their 2023-24 peak and a high trailing P/E that reflects those depressed profits. The mixed peer comparison and missing data on flows and news limit the conclusions. Whether profits stabilize is the main open question, and this data does not answer it.
