Haesung Optics is an optical-components company that makes OIS and AF actuators, which finely move the lens so a smartphone camera captures sharp images even when it shakes, and supplies them into the camera-module and smartphone supply chain. Having narrowed its business to OIS actuators and brought core processes in-house, its revenue has grown quickly, and it turned to profit alongside first-quarter 2026 revenue of ₩69.5 billion, so the forward P/E reflecting this year's profit is roughly in line with peers. What stands out lately is that the more the first-quarter profit hardens into operating profit and the balance sheet thickens, the stronger the case; on the other hand, a debt ratio of 631.7% and a current ratio of 63.8% leave short-term liquidity tight, one-off gains may be mixed into the first-quarter profit, and dilution from a rights offering and convertible-bond conversion is underway.

🔎 In-depth analysis

🏢Business
  • Haesung Optics is an optical-components company that makes and sells the OIS (optical image stabilization) and AF (autofocus) actuators used in smartphone cameras.
  • In the past it also made lens modules and camera modules, but it has wound those down, and now the core of its revenue is the small drive component (VCM/OIS actuator) that finely moves the lens so photos come out sharp even when the camera shakes.
  • In other words, it earns money not by selling finished cameras but by supplying the precision drive components inside them into the camera-module and smartphone maker supply chain.
  • It is a smartphone-parts supplier-type business where unit prices are low and results swing with customer order volumes; recently it has narrowed its business to OIS actuators and brought core processes in-house to refine its cost structure.
📈Price & chart
  • The latest close is ₩941 and market capitalization is ₩55.7 billion.
  • The price sits below its 20-day line (₩1,103) and below its 60-day line (₩1,610).
  • Trading beneath both the short- and mid-term moving averages, the trend is on the soft side.
  • The RSI (a supplementary gauge that weighs recent up-moves against down-moves over the past 14 days on a 0-100 scale) is 32.0, a neutral reading.
  • The one-month change is -32.3%, the three-month change is -31.1%, and the price stands -66.2% from its 52-week high.
  • Relative strength versus the KOSDAQ is 90 (on a 1-99 scale that converts the past year's return against the index while weighting more recent performance; higher means stronger than the market).
  • That places it roughly in the top 9% for strength among all listed stocks.
  • Over the past three months it lagged the index by 14.0%.
  • Chart reading is best done together with volume and disclosure dates.
📊Key metrics
  • Valuation has to be viewed in two parts.
  • Because 2025 was a loss year, no P/E (how many times a year's earnings the price is) can be set on last year's confirmed results, but this does not mean the company is expensive; it simply reflects that a trailing metric loses meaning in a loss-making period.
  • Instead, the forward (projected) P/E reflecting this year's profit sits not far from profit-based peers (Jahwa Electronics at around 13x, for example).
  • The P/B (how many times net assets the price is) is 2.79x, and the forward P/B reflecting this year's equity increase is 2.79x.
  • On profitability, 2025 ROE (how much a company earns in a year on its equity) was -46.3% and the operating margin was -4.2%, both loss-making.
  • The balance sheet is genuinely on the weak side: the debt ratio (debt relative to equity) is high at 631.7%, and the current ratio (assets convertible to cash now against debt due within a year) of 63.8% is below 100%, so short-term liquidity is tight.
  • With ₩18.6 billion in equity against ₩117.5 billion in debt, the key variable is that until profit accumulates and thickens equity, even small swings in profit or loss can shake the balance sheet.
🚀Growth
  • The top line and the bottom line turned together.
  • 2025 revenue was ₩160.3 billion, up 47.7% year on year, and first-quarter 2026 revenue was ₩69.5 billion, up 125% from the same period last year.
  • Above all, the biggest change is that a bottom line that had been in the red through 2025 turned to profit in the first quarter of 2026, with operating profit of +₩0.7 billion and net profit of +₩3.5 billion.
  • The fact that a forward P/E reflecting this year's profit can be produced is a value that captures exactly this inflection.
  • Narrowing the business to OIS actuators and bringing processes in-house to cut costs, together with parts demand and volumes strong enough to more than double first-quarter revenue, underpin this year's earnings.
  • That said, first-quarter net profit (₩3.5 billion) being larger than operating profit (₩0.7 billion) suggests one-off non-operating gains may be mixed in, so it is important to confirm quarter by quarter whether this profit continues on an operating basis.
  • If profit hardens on an operating base, the forward-based valuation is not heavy relative to the pace of top-line growth.
📰Recent news & filings
  • The main threads of recent disclosures are financing and sharp price moves.
  • In June 2026 the company decided on a roughly ₩5.0 billion third-party allocation rights offering, earmarked for automation equipment (facilities funds) and operating funds, and in May came a series of disclosures on the exercise of convertible-bond (CB) conversion rights and conversion-price adjustments.
  • This signals that it is covering facilities investment and operating funds through external financing and share conversion, which reflects intent to expand the business but also dilutes existing shareholders' stakes.
  • On May 14 it filed its first-quarter 2026 quarterly report, confirming revenue of ₩69.5 billion and a turn to operating and net profit, and in early May it answered the exchange's inquiry on the notable price swing with 'no material information', showing that the price moved sharply without any undisclosed catalyst.
🧭Bottom line
  • This is a stock where both strengths and weaknesses are pronounced.
  • The strong side is the business-structure improvement and the earnings inflection.
  • By narrowing its business to OIS actuators and bringing processes in-house, revenue grew quickly and turned to profit in the first quarter of 2026, and the forward P/E reflecting this year's profit is roughly in line with peers, so it is not an overstretched level relative to top-line growth.
  • The fact that the P/E cannot be set because of losses, or that the P/B looks high, is not evidence of being expensive but a limitation of trailing metrics; the real picture is in the forward figures.
  • The weak side is the balance sheet and the durability of the profit.
  • A debt ratio of 631.7% and a current ratio of 63.8% leave short-term liquidity tight, and because one-off gains may be mixed into the first-quarter profit, whether it is operating-based profit needs more watching.
  • Dilution from the rights offering and CB conversion, raising the share count, is also underway.
  • In short, the more the first-quarter profit hardens into operating profit and the balance sheet thickens, the stronger the case; if the profit proves one-off or financing recurs while equity fails to support it, the weaker.
  • This is not a call to buy or sell, but a stock to judge by two conditions: the durability of the profit and improvement of the balance sheet.

🔎 Valuation vs peers Overvalued

Suppliers of smartphone camera drive components (VCM/OIS and AF actuators) and camera modules; the peer set places Jahwa Electronics (VCM/OIS actuators), whose business substance is closest, alongside camera-module makers MCNEX and Partron.

PeerP/EP/BROE
Jahwa Electronics11.92x1.26x10.60%
MCNEX6.17x0.83x13.37%
Partron8.49x0.56x6.60%

The peers, Jahwa Electronics (P/E 15.2x, P/B 1.61x), MCNEX (P/E 7.3x, P/B 0.98x) and Partron (P/E 9.5x, P/B 0.63x), are all profit-based with a P/B around 1x. Haesung Optics, loss-making as of 2025 so that no P/E can be set, nonetheless carries a P/B of 3.57x, two to three times higher than its peers. In other words, within the same components sector a clear premium to asset value is attached, and this appears to reflect an expectation, priced in ahead, that this year's turn to profit will continue. On last year's confirmed (trailing) results it looks expensive for lack of earnings, and on a forward basis assuming this year's profit the burden eases, but that forward figure depends entirely on the assumption that the first-quarter profit continues without one-off items. Taking into account that the balance sheet (debt ratio 631.7%, current ratio 63.8%) is far weaker than peers, it is reasonable to view the stock as positioned high relative to peers until the durability of the profit is confirmed.

The latest close is ₩941 and the market capitalization is ₩55.7 billion. The price sits below its 20-day moving average (₩1,103) and below its 60-day moving average (₩1,610). 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 32.0, a neutral level. The one-month change is -32.3%, the three-month change is -31.1%, and the position relative to the 52-week high is -66.2%. Relative strength versus the KOSDAQ is 90 (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 91% of all stocks. Over the past three months it lagged the index by 14.0%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.

What stands out

  • Revenue grew 47.7% year over year, a sign of growth.

Points to watch

  • Debt far exceeds equity (debt ratio 631.7%).
  • Assets that can be turned to cash within a year fall short of near-term liabilities (current ratio 63.8%).
  • The most recent full year was a loss, so it is worth checking whether profitability recovers.
  • The price is high versus peers, so expectations already appear priced in.

📖 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 (%).
