Aton아톤

Aton's trailing revenue and operating profit are still solid, but earnings have fallen sharply from the 2022 and 2024 peaks and the share price has dropped over the past year.

Aton is a Korean fintech firm that sells authentication, electronic signature and security products mainly to banks, securities firms and mobile carriers. For the twelve months to H1 2026 it reported revenue of about ₩63.2B... more precisely ₩63.2B is wrong in scale, so it is ₩63.2B revenue, ₩10.2B operating income and ₩3.6B net income, while free cash flow was negative at about -₩25.0B.

What stands out

• Revenue has held roughly flat at about ₩63–68B in recent years, with 2025 growth of 3.3% after 18.9% in 2024.
• Net income fell from ₩10.5B in 2024 to ₩1.5B in 2025, and trailing net margin is 5.6% against a 16.2% operating margin.
• Trailing free cash flow is about -₩25.0B against ₩52.0B of borrowings and ₩25.3B of cash, so debt is a notable point to consider.
• At ₩5,000 the shares are down 32.4% over one year but up 29.9% over three months; the stock sits between its 52-week low of ₩3,300 and high of ₩11,370.
• The in-house DCF model gives a base value of ₩7,426 with a bear case of ₩4,684 and bull case of ₩11,882, but this is a model output, not a forecast.

What to watch

• The next filed results and cash flow trend, given the negative trailing free cash flow and rising borrowings relative to cash.
• Foreign ownership fell from 3.4% to 2.3% over 60 days; further changes in investor flows may be worth tracking.
• Recent governance filings, including a CEO change, an extraordinary shareholders' meeting and a head office relocation, and the data does not explain their business impact.
