Mirae Nanotech is a materials company that makes optical films which make TV and display screens brighter and sharper, supplying them to Samsung Electronics' large QLED TVs of 65 inches and up. Through its 2022 acquisition of Mirae Advanced Materials (an 85% stake), it expanded into the secondary-battery materials business, supplying lithium compounds for battery cathode materials to large domestic cathode-material makers. It completed a treasury-share disposal in January 2026 and disclosed a decline in 2025 results in February, yet its secondary-battery-materials subsidiary supported net profit, and Q1 net profit rose year on year, showing a structure in which the subsidiary's growth offsets weakness in the core business. What stands out recently is that, at a P/B of 0.76x and with a forward P/E on this year's expected earnings similar to or below peers, the price is not much of a burden on the premise that the earnings recovery continues; on the other hand, if the optical-film demand slump drags on, or given how much net profit leans on the subsidiary and non-operating items, that durability could waver, and a debt-to-equity ratio of 220% and an interest-coverage ratio below 1x are financial points to check together.

🔎 In-depth analysis
- Mirae Nanotech is a company that makes optical films (thin sheets that gather or diffuse light) which make TV and display screens brighter and sharper.
- About half of its revenue comes from here, and in particular they go into Samsung Electronics' large QLED TVs of 65 inches and up.
- On top of this, in 2022 it acquired Mirae Advanced Materials (currently an 85% stake) and expanded into the secondary-battery (battery) materials business.
- This subsidiary supplies lithium compounds used in battery cathode materials (the key material forming a battery's positive electrode) to large domestic cathode-material makers.
- In sum, it is a materials company that holds both 'display optical film (core business) + secondary-battery materials (growth axis)'; classified under rubber and plastics by industry code, its actual business is closer to display and battery materials.
- The latest close is 7,250 won and the market cap is 224.8 billion won.
- The price sits below both the 20-day line (7,524 won) and the 60-day line (8,763 won).
- Trading below both its short- and mid-term moving averages, the trend is on the subdued side.
- The RSI (a supplementary gauge comparing upward and downward force over the past 14 days on a 0-100 scale) is 46.5, a neutral level.
- The one-month change is +4.6%, the three-month change is -20.8%, and the position versus the 52-week high is -46.5%.
- Relative strength against KOSDAQ is 61 (1-99, converting the past year's return versus the index with more weight on recent performance; higher means stronger than the market).
- That places it in roughly the top 38% of all stocks by strength.
- Over the past three months it has led the index by 3.1%.
- It is best to read the chart alongside trading volume and disclosure dates.
- The P/B (how many times net assets the share price is) is 0.75x, so it trades below its book net assets.
- The P/E (how many times a year's earnings the share price is) is 16.49x on last year's confirmed earnings (trailing), and there is a reason this number alone looks high.
- As 2025 net profit fell temporarily, the denominator shrank and the multiple looks large - a common illusion at companies whose earnings are passing a bottom.
- On a forward P/E based on this year's expected earnings, it is much lower than the trailing 16.49x.
- Given that peers' P/Es are mostly in the 8-11x range, this year's earnings-based multiple is similar to or below peers, so there is no need to read the trailing P/E literally as 'expensive.' On profitability, ROE (how much is earned in a year on equity) is 4.6%, the operating margin is 3.9% and the net margin is 2.6%, still not high.
- The financials warrant a look: the debt-to-equity ratio (debt relative to equity) is somewhat high at 220%, the current ratio (assets quickly convertible to cash against debt due within a year) is 92.6%, slightly below 100%, and the interest-coverage ratio (how many times operating profit covers interest) is below 1x, so operating profit alone covers the interest burden only tightly.
- In sum, the asset and earnings-value side is priced low, while the financial structure has limited slack.
- The top line and earnings point in different directions.
- Revenue fell for two straight years, from 694.0 billion won in 2023 to 622.3 billion won in 2024 to 538.5 billion won in 2025, and Q1 2026 revenue also fell 26% year on year, against a backdrop of slowing TV demand for the core optical-film business.
- Earnings, by contrast, show a clear recovery track.
- Net profit turned to a profit of 22.1 billion won in 2024 and 13.8 billion won in 2025 from losses of -7.9 billion won in 2022 and -1.2 billion won in 2023, and Q1 2026 net profit was 10.3 billion won, actually up 8.8% year on year.
- Q1 net profit (10.3 billion won) exceeds operating profit (8.5 billion won), meaning profit was added beyond the core business from the subsidiary and non-operating items.
- In other words, even as revenue scale shrank, the secondary-battery-materials subsidiary supported profit so that total net profit grew.
- The forward P/E on this year's expected earnings falling also reflects the assumption that earnings, having passed last year's bottom, continue the recovery seen in Q1.
- The wider this recovery grows, the more the core-business revenue decline halts and the subsidiary's supply expands.
- The recent flow centers on the treasury-share disposal, results changes, and routine disclosures.
- In January 2026 it decided on and completed a treasury-share disposal, putting shares it held onto the market, and in February a disclosure of a change of 30% or more in revenue or profit structure reported the decline in 2025 results.
- This was followed by the March annual general meeting and business report and the May Q1 quarterly report.
- The most meaningful change on the business side is the expansion of secondary-battery-materials supply by the 85% subsidiary Mirae Advanced Materials, showing a structure in which the subsidiary's growth offsets weakness in the core business (optical film).
- The key is how to read the mixed picture of 'earnings recovery amid a weak core business.' Optical-film revenue is falling, but the secondary-battery-materials subsidiary supported net profit so that Q1 net profit rose year on year.
- On valuation, a P/B of 0.76x is below net assets, and the forward P/E on this year's expected earnings is similar to or below peers, so on the premise that the earnings recovery continues, the price is not much of a burden.
- The strong case is clear: if the subsidiary's revenue and profit actually expand and the core-business revenue decline halts, a recovery scenario of rising earnings with a low valuation gains momentum.
- Conversely, the weak case is twofold: if the optical-film demand slump drags on, and if - given how much net profit leans on the subsidiary and non-operating items rather than the core business - that profit's durability wavers.
- Also, with a debt-to-equity ratio of 220%, a current ratio of 92.6% and an interest-coverage ratio below 1x, the limited slack in debt and short-term funding is a point to check together.
- In sum, it is a recovery candidate whose asset and earnings value is priced low, with clear strengths, but whether earnings quality and financial headroom support that recovery to the end is the fork.
🔎 Valuation vs peers Inconclusive
Compared with listed companies among display and electronic-component materials makers whose business character is close; display and electronic-materials makers are taken as the reference group given the optical-film (core business) and materials diversification.
| Peer | P/E | P/B | ROE |
|---|---|---|---|
| Innox Advanced Materials | 7.37x | 1.09x | 14.75% |
| KNJ | 8.01x | 2.12x | 26.43% |
The comparables Innox Advanced Materials (P/E 10.0x, ROE 14.8%) and KNJ (P/E 11.2x, ROE 26.4%) have growing earnings and higher profitability (ROE 4.6% for Mirae Nanotech). So on the trailing P/E of 16.2x alone, Mirae Nanotech looks expensive. But this largely reflects the shrunken denominator from 2025 net profit being at an inflection (trough). Reflecting earnings recovering this year as in Q1, the forward multiple falls to a level similar to or below peers (about 9.3x). In other words, (a) profitability versus peers is still inferior, but (b) there is an asset-value discount in the P/B of 0.75x, and (c) last year's trailing P/E has a limit in looking overvalued due to the earnings trough. Because the outcome hinges heavily on whether the earnings recovery actually continues, it is hard to conclude either way, so the verdict is Inconclusive.

Key metrics vs sector median
Valuation
The P/E of 16.27x is above the sector median (12.90x). The P/B is 0.75x.
Enterprise value (EV)
EV = market cap + net debt. It reflects cash and debt, so it captures the real cost of the whole business that market cap alone misses; lower multiples are cheaper relative to earnings or sales.
Intrinsic value (DCF estimate)
DCF (discounted cash flow) estimate — discount rate 9.2%, initial growth 4.0%→terminal 2.0%, 10-yr forecast, earnings-based. A reference range that shifts materially with assumptions.
Profitability & financials
Return on equity (ROE) is 4.6%, below the sector average (6.0%). The operating margin is 3.9%. The debt ratio is 220.0%, so the financial structure is somewhat high.

📖 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 (%).
