Taihan Cable & Solution: Revenue Growth Continues, but Trailing Earnings Turn Negative After a Sharp Share Price Pullback

Thesis

The data supports a picture of steady top-line growth: revenue rose every year from ₩2.0T in 2021 to ₩3.6T in 2025, and trailing revenue is ₩4.1T. Operating income also improved, with trailing operating income of ₩194.2B and a 4.7% operating margin versus 3.5% in 2025.

The data does not show that this has reached the bottom line. Trailing net income is -₩15.4B, a net margin of -0.4%, and trailing free cash flow is deeply negative. The share price is 66.1% below its 52-week high of ₩75,900 and 61.0% above its low of ₩15,960, so the stock has been volatile. The reasons for the recent decline are not available, as no news headlines were provided. Investor flows, foreign ownership and short balance data are also not available.
