SD system is a Korean specialist in highway toll collection and intelligent transport systems, serving government bodies, the Korea Expressway Corporation and private road operators. Trailing twelve-month figures to H1 2026 show revenue of ₩20.7B...

What stands out

• Trailing revenue is about ₩20.7B, but operating income is roughly -₩0.8B, a -3.7% operating margin, compared with a 3.8% operating margin in 2025.
• Trailing net income is positive at about ₩0.4B, yet free cash flow is about -₩2.6B, and the data does not explain the gap.
• The share price closed at ₩2,485 on 2026-10-27, down 9% over one month but up 36.3% over one year, within a 52-week range of ₩1,312 to ₩2,995.
• The fair value model gives a base of ₩489 against the ₩2,485 close, with bear ₩65 and bull ₩1,274; the model's inputs are not explained in the data.
• Trailing P/E is 81.2 and P/B is 3.2, above the peers listed, and the company pays no dividend. Foreign ownership rose from 16.1% to 18.2% over 60 days.

What to watch

• Full-year 2026 results, since the trailing figures cover only the first half and the company returned to an operating loss.
• Details of the extraordinary shareholders' meeting held in July 2026, which the filing titles do not describe.
• No recent news headlines were supplied, so the data does not show the reason for recent share price moves.
