VUNO applies deep-learning technology to medicine, supplying hospitals with software that uses artificial intelligence to analyze medical images such as X-ray, CT, MRI and fundus photographs, along with signals like ECGs, to help clinicians make diagnoses, earning usage fees and product sales in return; it was the company behind Korea's first AI medical device in 2018. Corrective filings on single supply contracts followed in August-September 2025, and in February 2026 there was a filing on acquiring convertible bonds before maturity after issuance (₩1.6 billion in bond value, conversion price ₩25,337). On the plus side, from its leading domestic position in the growth field of medical AI, revenue is climbing fast and the operating loss has narrowed from -₩15.7 billion to -₩4.9 billion over two years, approaching break-even; on the cautious side, the company is not yet profitable, so quarterly results vary widely, and growth can be uneven, as seen in Q1 2026 revenue falling from a year earlier.

🔎 In-depth analysis

🏢Business
  • VUNO earns its money by applying deep learning (an AI approach that learns rules on its own from data) to the medical field.
  • It is regarded as the company that first opened Korea's AI medical-device market, launching the country's first AI medical device, 'VUNO Med-BoneAge,' in 2018.
  • Its mainstay is software that uses AI to analyze medical images such as X-ray, CT, MRI and fundus photographs, and biosignals such as ECGs, to help clinicians make diagnoses.
  • The model is to supply solutions to hospitals and receive usage fees and product sales, and it also runs side businesses such as medical-device repair and the sale of diabetes consumables.
  • Because its market cap is on the smaller side, it helps to look not only at the business itself but also at the effect each contract filing has on revenue and the share count.
📈Price & chart
  • The latest close is ₩7,770 and the market cap is ₩108.8 billion.
  • The price sits below its 20-day line (₩8,014) and its 60-day line (₩11,572).
  • Trading below both the short- and mid-term moving averages, the trend is on the soft side.
  • The RSI (an indicator that weighs the strength of recent gains against losses over the past 14 days on a 0-100 scale) is 39.8, a neutral reading.
  • It is down 0.4% over one month and 47.5% over three months, and sits 71.9% below its 52-week high.
  • Relative strength versus the KOSDAQ is 14 (on a 1-99 scale that converts return against the index over the past year with more weight on recent performance; higher means stronger than the market), placing it in roughly the top 87% of all stocks for strength.
  • Over the past three months it has lagged the index by 32.2%.
  • Chart reading is best done alongside trading volume and the dates of filings.
📊Key metrics
  • Full-year 2025 revenue was ₩34.8 billion, with an operating loss of -₩4.9 billion and a net loss of -₩5.8 billion.
  • The operating margin was -14.2% and ROE (how much is earned in a year on shareholders' equity) was -16.0%, still in loss territory.
  • That said, the debt ratio of 139.5% is not heavy, and a current ratio (assets convertible to cash within a year against debt due within a year) of 305% means short-term liquidity is comfortable.
  • Because earnings are still negative, a P/E cannot be calculated, and the P/B is 3.01x.
  • For a loss-making company, the P/B is less a yardstick of expensive-versus-cheap in itself than a figure whose meaning depends on whether the company can turn profitable ahead.
🚀Growth
  • The heart of the growth story is that two things are improving at once.
  • Revenue rose from ₩13.3 billion in 2023 to ₩25.9 billion in 2024 and ₩34.8 billion in 2025, a two-year average of about 62% growth, while over the same span the operating loss narrowed quickly from -₩15.7 billion to -₩12.5 billion and then -₩4.9 billion.
  • The net loss also shrank from -₩15.6 billion to -₩5.8 billion.
  • As revenue grows, the effect of spreading fixed costs kicks in, and the company appears to have entered the phase, typical of AI-solution businesses, where losses shrink sharply once revenue passes a certain scale.
  • Revenue for 2026 is estimated at roughly ₩32.2 billion, but Q1 revenue of ₩6.0 billion (down 19.7% year on year) marks a pause that should be viewed as quarterly volatility.
  • Whether the trend of approaching break-even (the point where revenue equals costs, so there is neither loss nor profit) stays alive, and whether the loss keeps shrinking quarter after quarter, are the points to watch from here.
📰Recent news & filings
  • Looking at the flow of filings, corrective disclosures on single supply contracts followed in August-September 2025.
  • More than the contract amounts themselves, whether those contracts are one-off or repeatable is the key to how future revenue is recognized.
  • In February 2026 there was a filing on acquiring a convertible bond (a bond that can be converted into shares) before maturity after issuance (₩1.6 billion in value, conversion price ₩25,337).
  • Because a convertible bond brings in funds but can later increase the share count, it helps to check the intended use of the funds alongside any change in the share count.
🧭Bottom line
  • The strengths are clear.
  • In the growth field of medical AI it holds a leading domestic position, and as revenue climbs fast the operating loss has narrowed sharply from -₩15.7 billion to -₩4.9 billion over two years, closing in on break-even.
  • Debt and short-term liquidity are also relatively stable.
  • On the cautious side, the company is not yet profitable, so quarterly results vary widely, and growth can be uneven, as in Q1 2026 revenue falling from a year earlier.
  • In short, if revenue growth continues and the loss-narrowing trend is confirmed quarter by quarter, the stock could be re-valued quickly along with crossing break-even; conversely, if revenue growth stalls or the loss-narrowing slows, the timing of turning profitable moves further out.

Operating results are in the red, so a swing back to profit matters more than the growth rate here. Over the 5 years on record, revenue compound annual growth (CAGR) is 98.4%. The two-year revenue CAGR is 62.0%. In the most recent quarter (Q1 2026), revenue was 19.7% lower than the same period a year earlier.

📖 Plain-language glossary — expand if you are new to this
P/E
How many times a year's net profit the price is worth (lower is cheaper relative to earnings). The P/E here is on trailing (last full-year) results; for companies whose earnings swing fast (memory chips and other cyclicals/high-growth), a forward P/E on this year's expected earnings is more accurate.
P/B
Price relative to net assets (equity). Around 1x means it trades near book value; below 1x means below book.
P/S
Price relative to a year's revenue — useful for growth companies with thin earnings.
Net debt / EV
Net debt = interest-bearing debt − cash. Negative means more cash than debt (net cash). EV (enterprise value) = market cap + net debt, closer to what it would cost to buy the whole business.
EV/EBIT · EV/EBITDA · EV/Sales
Enterprise value against operating profit (EBIT), EBITDA, or revenue. Unlike P/E these reflect debt and cash; lower is cheaper relative to earnings power or sales.
FCF / FCF yield
Free cash flow = operating cash − capex, the cash actually left over. FCF yield = FCF ÷ market cap; higher means more cash generated per unit of market value.
Intrinsic value (DCF)
Future free cash flow (or, for some capex-heavy but profitable names, forecast earnings) discounted to today to estimate per-share value. Because it shifts a lot with the discount-rate and growth assumptions, it is shown as a bear/base/bull range, and the basis and assumptions are disclosed in one line beneath it.
ROE
How much profit the company earns in a year on its equity (%). Higher means better returns on capital.
EPS / BPS
Earnings per share / net assets (book value) per share.
Operating / net margin
Profit left from the core business / final profit after tax and interest, per unit of revenue.
Debt ratio
Debt relative to equity (%). Higher means more reliance on borrowing (norms vary by sector).
Current ratio
Assets convertible to cash within a year against debt due within a year. Above 100% leaves some short-term headroom.
Interest coverage
How many times operating profit covers the interest owed. Below 1x means operating profit alone struggles to cover interest.
Dividend yield / payout ratio
The year's dividend as a % of today's price / the share of earnings paid out as dividends.
Revenue CAGR
Multi-year growth expressed as a single yearly average (compound annual growth rate).
RSI (short-term signal)
Whether recent price action is overheated or beaten down. Above 70 is overbought, below 30 oversold.
MA20 / MA60 (moving averages)
The 20- and 60-day average price. Price above them signals a firmer short-term trend.
vs 52-week high
How far below the past year's peak the price sits now (%).
