Amosense supplies materials and components that, inside phones, automotive electronics and industrial devices, block electromagnetic interference (shielding) or help transmit the signal and power for wireless charging and near-field communication — in short, it sells intermediate goods that go inside finished products and let other components do their jobs without interference. Recent disclosures have leaned toward financing: in July 2025 it decided to issue a convertible bond (conversion price ₩7,537), and that same month it filed to acquire existing convertible bonds before maturity (₩10.0 billion and ₩5.0 billion). What stands out lately is that, on the strength side, it has a history of expanding revenue to as high as the ₩130 billion range, a P/B of 1.76x that is not excessively expensive against asset value, and a share price already down more than 70% from its high; on the caution side, revenue and profit are both shrinking in a de-growth phase, and with a debt ratio of 317% and an interest-coverage ratio below 1x, financial headroom is tight — so both the profit-recovery question and the debt burden must be watched together.

🔎 In-depth analysis
- Amosense is an electronic-components company.
- Inside phones, automotive electronics and industrial devices, it mainly supplies materials and components that block electromagnetic interference (shielding) or help transmit the signal and power for wireless charging and near-field communication.
- Put simply, it sells intermediate goods that go inside finished products — inconspicuous but essential — and let other components do their jobs without interfering with one another.
- With a market cap of ₩75.9 billion it is a small-cap, so alongside the flow of the business itself, one must also watch how a single disclosure (financing, share-count change, etc.) affects the finances and the share price.
- The latest close is ₩5,740 and the market cap is ₩67.7 billion.
- The price sits below both the 20-day line (₩7,490) and the 60-day line (₩13,269).
- Trading under both its short- and mid-term moving averages, the trend is subdued.
- RSI (an indicator that gauges upward versus downward force over the past 14 days on a 0-100 scale) is 29.7, close to a depressed zone.
- The price is down 37.4% over one month and 61.5% over three months, and sits 77.1% below its 52-week high.
- Relative strength versus the KOSDAQ is 70 (1-99, weighting recent returns against the index over the past year more heavily; higher means stronger than the market), placing it in roughly the top 30% of all stocks by strength.
- Over the past three months it has lagged the index by 42.4%.
- Chart readings are best interpreted alongside trading volume and disclosure dates.
- The most recent annual (2025) revenue was ₩122.1 billion, with operating profit of ₩5.3 billion and net profit of ₩0.5 billion.
- The operating margin of 4.4% is on the thin side, and because net profit is so small, the P/E ratio (how many times a year's net profit the price is) prints high at 152.6x.
- This figure, however, is less a sign that the company is expensive than a result of net profit being nearly zero, shrinking the denominator, so rather than reading it straight as "overvalued," it takes on meaning only if one watches whether profit grows again.
- The P/B (how many times book value the price is) is 1.56x, not a level that is heavily burdensome against asset value.
- The more important weakness is the financial structure: the debt ratio (debt against equity) is 317.1%, with debt more than three times equity, and the interest-coverage ratio (how many times operating profit can cover interest) is 0.92x, below 1x, meaning a year's operating profit is barely enough to cover interest.
- ROE (how much profit is generated on equity in a year) is a low 1.1%.
- Rather than valuation, this financial burden is the key checkpoint for this stock.
- Over the long run, revenue expanded from ₩56.8 billion in 2021 to ₩87.5 billion in 2023 and ₩134.2 billion in 2024.
- Operating profit also has a track record of recovering from a roughly ₩0.8 billion loss level in 2023 to ₩7.2 billion in 2024.
- The problem is the most recent period.
- 2025 revenue was ₩122.1 billion, down 9.0% from the prior year, and operating profit fell 25.7%.
- On a cumulative Q1 2026 basis as well, revenue was ₩27.8 billion, down 10.7% year over year, and operating profit dropped 65.3%.
- In other words, the outsized expansion has pulled back and profit has fallen more steeply.
- This year's full-year outlook is set at around ₩136.9 billion in revenue and ₩3.4 billion in operating profit — a picture where the top line recovers slightly from last year but the margin side is still thin.
- Whether end-market electronic-component demand revives and the profit that shrank in Q1 recovers through the quarters is the most important variable for this year's outlook being realized.
- Recent disclosures are concentrated on financing.
- On July 16, 2025, the company decided to issue a convertible bond (a bond that can be converted into shares) (conversion price ₩7,537), and on the 24th of the same month it filed to acquire existing convertible bonds before maturity (bond amount ₩10.0 billion at conversion price ₩9,140, and ₩5.0 billion at conversion price ₩8,062).
- A convertible bond has two sides: it brings in funds while, if later converted into shares, it can raise the share count and dilute existing shareholders' stakes.
- It is therefore worth following through IR and subsequent disclosures whether these funds go to facilities or operations and link to real revenue and profit, and how much the share count changes upon exercise of conversion rights.
- The strengths are clear.
- In a space with steady demand for electromagnetic-shielding and wireless-charging materials, it has a history of expanding revenue to as high as the ₩130 billion range; a P/B of 1.76x is not an excessively expensive zone against asset value; and the share price is already down more than 70% from its high, so the weaknesses are substantially reflected.
- With RSI in a depressed zone, the burden of a short-term drop has also eased.
- On the other hand, the cautions are just as clear.
- Revenue and profit are both shrinking in a de-growth phase, and with a debt ratio of 317% and an interest-coverage ratio below 1x, financial headroom is tight, so if profit wobbles further the interest and repayment burden can grow.
- The possibility of a share-count change from convertible bonds is another variable.
- In sum, this is a stock where a low P/B and a depressed share price can become a springboard for recovery if the shrunken profit turns around as this year's outlook expects and the financing flows through to real business results, and where the heavy debt weighs more as a weakness if the top-line decline and thin profit persist.
- Ultimately, watching both axes — the profit-recovery question and the financial burden — is the key.

The primary reference was a public-data peer set within electronic components and displays adjacent by market cap. The current P/E ratio (how many times a year's profit the price is) is 136.02x and the P/B (how many times book value the price is) is 1.56x. That said, for smaller-cap names, profit swings and financing filings have an outsized effect, so no firm conclusion was drawn from last year's confirmed-results metrics alone. The basis for the outlook box is a DART seasonality approximation.

Price history Close · MA20 · MA60
The latest close is ₩5,740 and the market capitalization is ₩67.7 billion. The price sits below its 20-day moving average (₩7,490) and below its 60-day moving average (₩13,269). It is under both its short- and medium-term moving averages, so the trend looks subdued. The RSI (a supplementary indicator that gauges the strength of gains versus losses over the past 14 days on a 0-100 scale) is 29.7, near oversold territory. The one-month change is -37.4%, the three-month change is -61.5%, and the position relative to the 52-week high is -77.1%. Relative strength versus the KOSDAQ is 70 (on a 1-99 scale, converted from returns against the index over the past year with more weight on recent performance; higher means stronger than the market). It is stronger than roughly 70% of all stocks. Over the past three months it lagged the index by 42.4%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.

Key metrics vs sector median
Valuation
The P/E of 136.02x is above the sector median (18.61x). The P/B of 1.56x is in line with the sector median (1.63x).
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 10.4%, initial growth 4.0%→terminal 2.0%, 10-yr forecast, free-cash-flow basis. A reference range that shifts materially with assumptions.
Profitability & financials
Return on equity (ROE) is 1.1%, below the sector average (7.0%). The operating margin is 4.4%. The debt ratio is 317.1%, 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 (%).
