Classys makes aesthetic medical devices such as its HIFU lifting device 'Shurink' and its radiofrequency device 'Volnewmer'. Its model is a 'razor-and-blade' one, in which once a device is sold, the clinic must keep buying the cartridges and tips consumed with each treatment, so about 46% of 2025 revenue came from consumables and its cumulative installed base exceeds 45,000 units worldwide. In May 2026 the company made a fair-disclosure of preliminary first-quarter results, and in March it acquired a Brazilian distribution subsidiary and merged with the domestic firm Iruda to broaden its sales regions and product lineup, while also paying a dividend of ₩1,000 per share (a yield of about 2.1%). What stands out is that an operating margin above 50%, recurring revenue, and a wide installed base are strengths, and the Brazil and Iruda additions plus Volnewmer's entry into China ease the valuation burden on this year's earnings; the caution is that aesthetic devices are swayed by the economy and licensing timelines, competition on new products and price with rivals such as Wontech is constant, and the results of the acquired subsidiaries and the trend in consumable repurchases bear watching.

🔎 In-depth analysis

🏢Business
  • Classys makes aesthetic medical devices.
  • Its flagship products are 'Shurink' (marketed overseas as Ultraformer), a HIFU device that uses ultrasound heat to lift the layers beneath the skin, and 'Volnewmer', which works on skin elasticity with radiofrequency (RF).
  • The business model is distinctive: rather than a one-time device sale, it is a 'razor-and-blade' arrangement in which the clinic must keep buying the cartridges and tips consumed with each treatment.
  • In fact, about 46% of 2025 revenue came from these consumables, and the cumulative installed base worldwide exceeds 45,000 units.
  • Because once a device is placed, consumable revenue steadily follows, recurring revenue grows as the installed base widens.
  • On top of this, in March 2026 the company acquired a Brazilian distribution subsidiary (MedSystems) and merged with the domestic aesthetic-device firm Iruda, broadening its sales regions and product lineup.
📈Price & chart
  • The latest close is ₩50,100 and the market cap is ₩3.3 trillion.
  • The price sits above its 20-day line (₩46,388) and above its 60-day line (₩49,981).
  • Above both its short- and medium-term moving averages, the trend is on the sound side.
  • RSI (an auxiliary gauge that scores the up-move versus down-move over the last 14 days on a 0-100 scale) is 57.2, a neutral level.
  • The one-month change is +15.7%, the three-month change is -2.3%, and the position relative to the 52-week high is -33.7%.
  • Relative strength against the KOSDAQ is 75 (1-99, a conversion of return versus the index over the past year weighted toward the recent period; higher means stronger than the market).
  • That places it in roughly the top 24% of all stocks by strength.
  • Over the past three months it led the index by 30.2%.
  • Chart readings are best viewed together with volume and disclosure dates.
📊Key metrics
  • Profitability stands out.
  • ROE (how much is earned in a year on shareholders' equity) is a high 23.9%, and the operating margin (the share of operating profit left from revenue) is 50.6%, very unusual for a manufacturer.
  • This owes to low-cost recurring consumable revenue underpinning the margin.
  • The balance sheet is also solid, with a comfortable current ratio (cash-like assets versus debt due within a year) of 369% and an interest coverage ratio (how many times operating profit covers interest) of 15.7x, so the debt burden is small.
  • The current P/E ratio (how many times one year's net profit the price is) is 24.77x and the P/B (how many times book net asset value the price is) is 5.91x, both on last year's reported earnings.
  • That said, this company is in a growth phase where earnings rise sharply each year, so the P/E calculated on last year's figures has the limitation of looking more expensive than it is.
  • Reflecting the profit that will be added this year, the multiple falls below 20x.
🚀Growth
  • The texture of growth is clear.
  • Revenue grew from ₩100.6 billion in 2021 to ₩336.8 billion in 2025, a five-year average of 35% a year, and looking at 2025 alone it rose 38.6%, so growth actually accelerated.
  • Operating profit (₩51.7 billion to ₩170.6 billion) and net profit rose in step over the same period.
  • In the first quarter of 2026 revenue grew 13.1% but operating profit fell 4.1%; this was not a break in demand but the overlap of one-off costs such as Brazil-acquisition advisory fees and marketing for a large trade show (KIMES).
  • Revenue from the acquired Brazilian subsidiary is reflected in earnest from the second quarter, and with the Iruda merger contribution and momentum from Volnewmer's entry into China added, profit follows a step-up trajectory into the second half.
  • Given this trajectory, this year's net profit is expected to comfortably exceed a simple quadrupling of the first quarter, so that on this year's earnings the valuation falls markedly below last year's basis.
📰Recent news & filings
  • Recent filings center on external expansion, shareholder returns, and results confirmation.
  • On May 13, 2026 the company fair-disclosed preliminary first-quarter results, and the Brazilian distributor acquisition completed in March secured a direct-sales base in South America.
  • In May, employee stock options and a debt guarantee related to a subsidiary were disclosed, items arising in the process of talent incentives and subsidiary consolidation.
  • It held investor briefings (IR) several times from April to June to keep up communication with investors, and also voluntarily disclosed a sustainability report.
  • The dividend is ₩1,000 per share for a yield of about 2.1% and a payout ratio (the share of net profit paid out) of 49%, so it pairs shareholder returns with growth-stock characteristics.
🧭Bottom line
  • The strengths are clear.
  • An operating margin above 50%, consumable recurring revenue accounting for about half of sales, and an installed base of more than 45,000 units across some 80 countries create a structure where money keeps coming once a device is placed.
  • Growth has continued for five years and the balance sheet is firm.
  • This year, the Brazil and Iruda additions and Volnewmer's entry into China are a phase that lifts profit, so even though last year's P/E looks somewhat high, on this year's earnings the burden clearly eases and the multiple falls to a level that is not unreasonable versus competitors.
  • The caution is that for aesthetic devices, revenue can be swayed by the economy, consumer sentiment, and each country's licensing timeline, and competition on new products and price with domestic rivals such as Wontech is constant.
  • Whether the acquired subsidiaries' results come on as planned and whether consumable repurchases keep rising are the points that will decide this company's trajectory.

🔎 Valuation vs peers Fairly valued

Compared against domestic listed companies in the same energy-based aesthetic medical device and regeneration business; Wontech (RF Oligio and others) is the closest pure aesthetic-device competitor, and Pharma Research is in the adjacent aesthetic and regeneration (Rejuran and others) business.

PeerP/EP/BROE
Wontech13.94x3.12x22.38%
Pharma Research19.44x4.66x23.95%

(a) Positioning versus peers: on last year's reported earnings, a P/E of 23.7x is higher than competitor Wontech (14.9x) and similar to Pharma Research (23.1x). The P/B is also 5.66x, higher than Wontech (3.34x). (b) Basis for the premium: the value above Wontech reflects differences in business quality - an overwhelming operating margin (in the 50s%), consumable recurring revenue accounting for about half of sales, and a far larger installed base - and is a premium that is substantially grounded. (c) Limits of trailing P/E and forward: the 23.7x P/E is on 2025 reported earnings, so in a growth phase where this year's earnings rise it looks more expensive than it is. Reflecting the profit to be added this year, the multiple falls below 20x and the gap with Wontech narrows. Taken together, rather than an unreasonable overvaluation, this is a fair range where the premium is backed by profitability and growth.

📖 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 (%).
