Every few months a new Korean beauty label goes viral on TikTok, sells out at Olive Young, and mints a hot IPO. Betting on which one wins next is a coin flip. But there is one company that gets paid whether the winner is d’Alba, a Perfect Diary, or a brand that doesn’t exist yet — because it physically makes the product for all of them. Meet the arms dealer of K-beauty.
🔑 Key Takeaways
- Cosmax is the picks-and-shovels play on K-beauty. It is an ODM — it formulates and manufactures cosmetics for roughly 4,000 corporate clients worldwide (Source: DART FY2025 annual report) — so its revenue tracks the whole category, not one fragile label.
- FY2025 was a record — but read the tax line. Revenue ₩2,398.8bn (+10.7% YoY) and consolidated net income ₩131.1bn (+48.3%), yet operating income rose only +11.6% and pre-tax profit +13.7%. Most of the headline jump came from a lower tax charge (Source: DART consolidated FY2025 filing).
- It trades like an industrial, not a beauty stock. ~17.0× earnings on DART’s own EPS of ₩10,847 and a 1.8% dividend yield (₩184,600 close, as of Jul 28, 2026) — a discount to premium brand owners like Amorepacific.
- Mind the ticker, and mind the family. The business is Cosmax Inc (192820) — not holding company Cosmax BTI (044820) or supplements affiliate Cosmax NBT (222040). And inside BTI, two brothers now hold exactly 24.34% each, with their mother’s 13.83% the deciding block.
💡 The “Arms Dealer” Thesis in One Line
Cosmax doesn’t own a single beauty brand — it makes products for thousands of them, which means it profits from the whole K-beauty boom instead of betting on one label winning. In a gold rush, the reliable money is in selling shovels, not panning for gold. Cosmax sells the shovels.
This is the opposite of a single-brand bet like d’Alba Global or APR, where the whole thesis rests on one brand staying hot. If a rival label steals d’Alba’s shelf space, d’Alba’s shareholders feel it. Cosmax likely makes products for both — so it barely notices which one is winning this quarter. Cosmax’s own FY2025 filing puts hard numbers on that diversification: no single external customer accounted for 10% or more of consolidated revenue in either FY2025 or FY2024 (Source: DART FY2025 consolidated notes, “major customers”). That is exactly what news aggregators and quote pages miss when they file Cosmax under “Korean cosmetics stock.”
🏭 What Is an ODM, and Why Does It Matter Here?
An ODM (original design manufacturer) both develops the formula and manufactures the product for a brand that puts its own name on the box — a step beyond an OEM, which only builds to someone else’s spec. When an indie label wants a new serum, it doesn’t build a lab and a factory. It goes to Cosmax, which already has the formulation, the regulatory know-how, and the production line. The brand handles marketing; Cosmax handles chemistry and scale.
Korea happens to own this layer of the global beauty supply chain. Cosmax, Kolmar Korea and Italy’s Intercos are the three cosmetics ODMs operating at genuine global scale, and two of the three are Korean. Cosmax says it supplies roughly 4,000 corporate clients across basic skincare, colour cosmetics and mask sheets, and its filing describes supplying a premium brand of “French group L”, a major Japanese brand house, and global consumer-goods majors — the names themselves are shielded by non-disclosure agreements (Source: DART FY2025 annual report, business overview). Treat any specific “Cosmax makes brand X” claim with caution unless the brand says so itself.
Cosmax added a European base in 2026, agreeing to buy 51% of Keminova, an ODM in Brescia’s “Beauty Valley” about 100km from Milan, with roughly ₩18bn of revenue and 20 million units of annual capacity — a small, customer-first entry rather than a greenfield build (announced Feb 2026; Korean press). It is a bridgehead, not yet a needle-mover.

📊 Was FY2025 Really a Record Year?
Yes on revenue and reported profit — Cosmax posted its best-ever year with revenue ₩2,398.8bn and consolidated net income ₩131.1bn — but the quality of that profit is lower than the +48% headline suggests, because operating income grew only +11.6% and the rest came from below the operating line.

💰 What Do You Actually Pay for Cosmax Today?
At ₩184,600 (Jul 28, 2026 close), Cosmax carries a market capitalisation of ₩2.10tn (about $1.4B) and trades at roughly 17.0× DART’s reported EPS of ₩10,847 — an industrial multiple for a company sitting at the centre of a consumer boom.

Market cap = 11,349,509 shares × ₩184,600. All price-derived figures are point-in-time — check a live quote before acting.
Two things stand out. First, the multiple you quote depends on which profit line you divide by. Cosmax consolidates majority-owned subsidiaries, so ₩8.0bn of FY2025 profit belonged to their minority holders, not to owners of 192820. Using consolidated net income makes the stock look like 16.0× when a 192820 shareholder is really paying 17.0×. That is the same accounting trap we unpack at much larger scale in the Kolmar Korea write-up, where the gap is ₩43bn rather than ₩8bn. Second, the stock sits about 31% below its 52-week high and near the low end of its range, up 13.3% year-to-date — well behind the profit growth, so the record year has not been re-rated. That is the value-versus-growth tension at the heart of this name.
🏷️ Which Cosmax Ticker Should You Actually Buy?
Only Cosmax Inc (192820) is the global cosmetics ODM; Cosmax BTI (044820) is the family holding company and Cosmax NBT (222040) is a health-supplements company that sits under BTI, not under Cosmax Inc. Foreign brokerages sometimes surface all three under “Cosmax,” and they are not interchangeable.
| Entity | Ticker | What it is |
|---|---|---|
| Cosmax Inc | 192820 (KOSPI) | The operating business — the cosmetics ODM. 99.98% of FY2025 revenue came from the cosmetics segment. This is the “arms dealer.” |
| Cosmax BTI | 044820 (KOSPI) | The family-controlled holding company that owns 27.23% of Cosmax Inc and is also the top shareholder of Cosmax NBT. |
| Cosmax NBT | 222040 (KOSDAQ) | The health-functional-food / supplements affiliate — a sister company held 43.95% by BTI, not a subsidiary of 192820. |
Source: DART FY2025 annual reports and large-holding reports (Cosmax Inc, Cosmax BTI, Cosmax NBT); BTI’s stake in NBT per its large-holding report filed Jul 6, 2026. Segment split per DART FY2025 consolidated note 37.
If your thesis is “K-beauty manufacturing,” the ticker you want is 192820. Buying BTI gives you the holding company — with its own discount, its own cross-holdings, and the succession question discussed below. Buying NBT gives you supplements, and it does not sit inside Cosmax Inc’s results at all.
🏛️ Who Actually Controls Cosmax — and What Do Minority Holders Get?
Cosmax Inc is controlled through the family holding company Cosmax BTI, which owns 27.23% directly (27.51% with related parties) — and inside BTI, the founder’s two sons now hold exactly 24.34% each, leaving their mother’s 13.83% as the block that decides the succession. This unresolved standoff is the single governance fact a foreign buyer of 192820 should know, and it appears in no English-language coverage we can find.
The control chain. Cosmax was founded in 1992 by Lee Kyung-soo. He is no longer among the holding company’s reported shareholders: he sold down his BTI stake in 2023 — at which point his wife, chairwoman Suh Sung-suk, became the lead reporting shareholder — and he does not appear in BTI’s June 2026 shareholder schedule at all. As of BTI’s most recent large-holding report (filed Jun 26, 2026), the family bloc holds 63.01% of Cosmax BTI, split as follows:
| Holder of Cosmax BTI (044820) | Shares | Stake |
|---|---|---|
| Lee Byung-man (elder son) — direct | 1,915,841 | 19.95% |
| SSY Co., Ltd. (100% owned by Lee Byung-man) | 421,670 | 4.39% |
| Elder-son bloc total | 2,337,511 | 24.34% |
| Lee Byung-joo (younger son) — direct | 1,010,361 | 10.52% |
| Cos M&M Co., Ltd. (100% owned by Lee Byung-joo) | 905,480 | 9.43% |
| BJH Co., Ltd. (100% owned by Lee Byung-joo) | 421,670 | 4.39% |
| Younger-son bloc total | 2,337,511 | 24.34% |
| Suh Sung-suk (chairwoman, mother) | 1,328,079 | 13.83% |
| Other related parties (foundation, executives) | 48,625 | 0.50% |
| Family bloc, total | 6,051,726 | 63.01% |
Source: DART large-holding report on Cosmax BTI, filed Jun 26, 2026 (9,603,921 voting shares outstanding). SSY and BJH were both newly incorporated in 2026 with ₩100m of capital each. Percentages as reported in the filing.
Read the table again: the two brothers’ blocs are identical to the share. That is not a rounding coincidence — SSY and BJH were incorporated in 2026 and each received precisely 421,670 shares. The mother’s residual 13.83% is therefore the swing block in any contest over the group. Lee Byung-man is an executive of Cosmax Inc; Lee Byung-joo is a registered director of the holding company, Cosmax BTI. Whichever way that 13.83% eventually moves will settle who controls the parent of the company whose shares you own. Nothing has been announced, and none of this is misconduct — but “succession unresolved at the holdco” is a live risk that a screener will never show you.
Outside shareholders. Korea’s National Pension Service is the largest outside holder at 12.85%, having added 230,966 shares over the quarter (Source: DART large-holding report filed Jul 1, 2026, position as of Jun 22, 2026). Singapore’s GIC and Norway’s Norges Bank are both 5%-plus holders — but moving in opposite directions, which we take up in the flow section below.
Shareholder returns. Cosmax raised its dividend to ₩3,300 per share for FY2025 from ₩2,300 for FY2024 — a 43% increase, a 1.8% yield at the Jul 28, 2026 close, and a cash payout ratio of 28.6% as reported by the company (Source: DART FY2025 dividend disclosure). That is not a token payout; it is roughly double what Kolmar Korea distributes. What is missing is the other half of Korea’s reform agenda: there is no large buyback-and-cancellation programme of the kind the Value-Up reform is trying to encourage, and cash is going into capacity — Korean nameplate capacity alone rose 31% in FY2025.
Governance risk to watch: the guarantee book. On Jun 29, 2026 Cosmax Inc’s board approved a guarantee of US$24m against US$20m of borrowing by Cosmax (Thailand) Co., Ltd. from Citibank’s Bangkok branch, running Jul 2026 to Jul 2027 — a rollover of a July 2025 guarantee. The line that matters is not that deal but the one beneath it: the filing puts Cosmax’s total outstanding guarantee balance at ₩393.6bn, against consolidated equity of ₩612.3bn — roughly 64% of book value (Source: DART, “decision to guarantee the debt of another party,” filed Jun 29, 2026). Guaranteeing overseas subsidiaries is normal for a manufacturer with plants on four continents, and none of it is on-balance-sheet debt. But it is contingent liability at scale, concentrated in the same emerging-market operations that drive earnings volatility — read it before you size a position.
🌏 Is Foreign Money Buying or Selling Cosmax?
Selling, on a short view: foreigners own 37.4% of Cosmax but have been net sellers for the past 20 trading sessions, offloading 109,553 shares (including 44,272 in the last five), while GIC cut its stake below 5.4% in July. The headline ownership number and the recent flow point in opposite directions, and most coverage quotes only the first.
The detail: GIC Private Limited reported a reduction to 603,144 shares (5.31%) on Jul 9, 2026, down 115,453 shares from its previous filing (Source: DART large-holding report, Jul 9, 2026). Pulling the other way, Norges Bank raised its holding to 6.08% on Jun 25, 2026, and the National Pension Service added over the same quarter. So this is not a stampede — it is a genuine two-sided debate among large institutions about whether a flat-margin, tax-flattered record year deserves a re-rating. Foreign-ownership and net-buy figures are as of Jul 28, 2026 (Source: Naver Finance foreign-flow series). For how these weekly flows read across the whole market, see our Foreign Flow Watch series.
🇨🇳 How Much Does China Still Matter?
A lot — China is both Cosmax’s biggest opportunity and its biggest swing factor, with Shanghai, Guangzhou and a Guangzhou joint venture together accounting for roughly 1.34 billion units of the group’s 2.67 billion units of annual capacity. That is half the production base pointed at one market.
Cosmax runs manufacturing corporations in Shanghai and Guangzhou serving the domestic Chinese beauty market — home to local brands and fierce price competition — plus a 342.8-million-unit joint venture with Yatsen Biotechnology in Guangzhou (Source: DART FY2025 annual report, capacity table). When China booms, Cosmax’s volumes and margins lift with it; when Chinese beauty demand softens or a plant runs at low utilisation, it drags group profit and adds foreign-exchange noise. Cosmax’s own filing flags USD, EUR and CNY as its principal currency exposures. This is why an ODM’s earnings can be lumpier than “4,000 clients” makes it sound: the client list is diversified, the factory base is not.
⚠️ The Bear Case (the ODM cohort risks)
- Structurally thin margins, and gross margin is going the wrong way. Operating margin is ~8% because the brand — not the manufacturer — captures the pricing power and the customer. Gross margin actually fell to 17.1% in FY2025 from 19.3% in FY2024; reported operating profit held up because SG&A came down. Cosmax will never carry a luxury brand’s margin.
- FY2025 profit is tax-flattered. A 16.3% effective tax rate versus 35.8% a year earlier did more for net income than the business did. Normalise the tax rate and the P/E is not 17×.
- Plant concentration, not customer concentration. DART confirms no customer is 10%+ of revenue — but roughly half of capacity sits in China, so utilisation and the yuan swing group profit year to year.
- Contingent liabilities. ₩393.6bn of outstanding guarantees against ₩612.3bn of equity, largely for overseas subsidiaries.
- Unresolved succession at the holdco. Two sibling blocs at exactly 24.34% each of Cosmax BTI, with the mother’s 13.83% undeclared. Group-level decisions may not always put the 192820 minority shareholder first.
- Capex-led, not return-led. A 28.6% payout is respectable, but cash is going into new capacity and there is no buyback-and-cancellation programme.
🗺️ Where Cosmax Sits in the ODM Landscape
Cosmax, Kolmar Korea and Italy’s Intercos are the three cosmetics ODMs at genuine global scale — and owning one of the Korean pair is the cleanest way to bet on K-beauty’s growth without picking a winning brand. Cosmax and Kolmar compete head-to-head for the same indie-brand and multinational accounts, with different geographic mixes, different business mixes, and very different governance.
We break the pair down in detail in the companion piece on Kolmar Korea stock — which is the post to read if you want the head-to-head, including why Kolmar’s consolidated earnings flatter its multiple far more than Cosmax’s do. For the contrast with the brand side of the trade — the premium houses that own the customer and the margin — see our look at Amorepacific’s valuation and China comeback. Together, the ODMs and the brands are two ways to express the same K-beauty thesis, with very different risk and margin profiles.

🎯 Why It Matters for K-Export Stars
Cosmax is a near-perfect fit for this site’s thesis: a Korean export champion selling into a global boom, sitting one layer below the brands the world already knows. It is a pure export-manufacturing play — the kind of company an owner-operator would call a real business, not a story. And it is the clearest single-stock way to own K-beauty’s structural growth without gambling on which label trends next quarter. It is also a case study in why we read the Korean filings rather than the English press release: the wires reported a record year, while the filing shows a flat operating margin, a one-off-looking tax rate, ₩393.6bn of guarantees, and two brothers deadlocked at 24.34% apiece. None of that makes Cosmax uninvestable. It makes it a stock you should size with your eyes open.
Conclusion
Cosmax (192820) lets you own the entire K-beauty supply chain instead of one fragile brand — record FY2025 revenue of ₩2,398.8bn at roughly 17.0× earnings, with the stock still 31% off its 52-week high (as of Jul 28, 2026). The bull case is structural: as long as indie brands keep launching, someone has to make the product, and only three companies do it at global scale. The bear case is equally structural: flat ~8% operating margins, a tax-flattered profit line, half the capacity pointed at China, ₩393.6bn of guarantees, and a holding-company succession that has not been settled. Just make sure you buy the right ticker — the ODM is 192820, not BTI (044820) or NBT (222040).
