Wooriro우리로

Wooriro's trailing profits have turned positive after losses in 2023 to 2025, but the shares have risen sharply and now trade at a very high earnings multiple.

Wooriro makes optical communication components for data centers and 5G networks, distributes storage products and imports audio brands. Trailing twelve-month figures to H1 2026 show revenue of ₩52.8B, operating income of ₩4.6B and net income of ₩3.6B, after a loss-making 2025 with revenue of ₩42.5B. The stock closed at ₩7,550 on 2026-10-27, with a market value of about ₩331B, a P/E of 91 and no dividend.

What stands out

• Trailing operating margin is 8.8% and net margin 6.9%, compared with an operating loss of ₩0.7B in 2025 and a net loss of ₩5.1B in 2024.
• Revenue has fallen for several years, from ₩107.4B in 2021 to ₩42.5B in 2025, before the recent trailing recovery.
• The shares are up 457.6% over one year and 94.1% over three months, but down 4.6% over one month, and sit well below the 52-week high of ₩16,200.
• In October 2026 the company announced a ₩22.8B optical semiconductor component order, after two earlier major supply contracts in September and October 2026. The filings do not give the customer or contract terms in the data provided.
• Over the last 20 days foreign investors were net sellers of about ₩4.2B, while retail investors were net buyers of about ₩1.8B; foreign ownership fell from 3.4% to 1.4% over 60 days.

What to watch

• Results for the full year 2026, since the trailing figures cover only the first half and the 2025 base was loss-making.
• Whether the recent supply contracts translate into sustained revenue, given the multi-year revenue decline.
• Balance sheet items: cash of ₩9.1B against borrowings of ₩8.9B, and liabilities at 42.2% of equity; the data does not include any risk disclosures beyond these figures.
