ESTsoft is a long-established maker of PC utility software such as ALZip, ALYac and ALTools, and it has broadened into gaming and artificial-intelligence (AI) services on top of that base. A February 2026 filing confirmed full-year 2025 revenue of ₩106.8 billion, an operating loss of ₩19.0 billion and a net loss of ₩17.7 billion, while Q1 2026 revenue reached ₩31.0 billion (up 22.9% year over year), extending three straight years of top-line growth as the business regains momentum at the revenue line. What stands out lately is that with a recognizable software base plus new AI and gaming ventures, if revenue growth can outrun costs and turn into a profit while debt stays managed, a share price that has fallen about 71% from its 52-week high could become a springboard for recovery; on the other side, the company is still running an operating loss, so earnings-based multiples cannot be used, and a debt ratio of 391% leaves little financial headroom.

🔎 In-depth analysis

🏢Business
  • ESTsoft is classified in the gaming and software sector.
  • It has long operated widely recognized PC utility software such as ALZip, ALYac and ALTools, and has expanded into gaming and artificial-intelligence (AI) services on top of that base.
  • With a market capitalization of ₩83.9 billion it is not a large company, so it is worth watching not only the underlying business trend but also how a single filing can affect earnings and the share count.
📈Price & chart
  • The latest close is ₩7,560 and the market cap is ₩88.9 billion.
  • The price sits below both the 20-day line (₩8,137) and the 60-day line (₩11,354).
  • Trading under both its short- and medium-term moving averages, the trend is on the soft side.
  • The RSI (a gauge that scores upward versus downward force over the last 14 days on a 0-100 scale) is 34.8, a neutral level.
  • The one-month change is -23.4%, the three-month change is -38.5%, and the price sits -67.0% from its 52-week high.
  • Relative strength versus the KOSDAQ is 19 (1-99, computed from returns against the index over the past year with more weight on recent performance; higher means stronger than the market).
  • That places it in roughly the top 82% of all stocks by strength.
  • Over the last three months it lagged the index by 19.8%.
  • Chart reading is best done alongside volume and the dates of filings.
📊Key metrics
  • Full-year 2025 revenue was ₩106.8 billion, with an operating loss of ₩19.0 billion and a net loss of ₩17.7 billion.
  • The operating margin was -17.8%, ROE (how much is earned in a year on equity) was -35.3%, and the debt ratio (debt relative to equity) was 391.4%.
  • Because the company is not yet profitable, the P/E ratio (how many times one year's earnings the price represents) cannot be calculated, and the asset-based P/B (how many times book value the price represents) is 1.77x.
  • A P/B of 1.67x is not unusually high for a lossmaking company, but what decides whether the stock is cheap or expensive right now is less the multiple itself and more whether it can swing from loss to profit.
  • With a large amount of debt relative to equity, interest burden and cash conditions also need to be watched.
🚀Growth
  • Revenue rose for three consecutive years, from ₩92.5 billion in 2023 to ₩102.5 billion in 2024 and ₩106.8 billion in 2025, and Q1 2026 revenue of ₩31.0 billion was up 22.9% from the same period a year earlier.
  • The recovery in the top line is a clear positive signal.
  • The operating result, however, has stayed in the red at -₩8.9 billion in 2023, -₩13.5 billion in 2024 and -₩19.0 billion in 2025, so even as revenue grows the cost structure has kept it from flowing through to profit.
  • The Q1 operating loss of -₩1.7 billion was narrower than the annual figure.
  • The forecast-box 2026 revenue (₩132.2 billion) and Q2 revenue (₩36.0 billion) are not official company or institutional earnings forecasts but approximations of the top line only, derived from confirmed quarterly results and past quarterly weightings; operating- and net-profit forecasts are not provided.
  • In short, this year's key question is whether revenue growth carries through to profit beyond the break-even point.
📰Recent news & filings
  • The filings center on earnings materials.
  • A February 25, 2026 filing on a change of 30% or more (15% for large corporations) in revenue or profit-and-loss structure confirmed full-year revenue of ₩106.8 billion, an operating loss of ₩19.0 billion and a net loss of ₩17.7 billion.
  • Fair-disclosure filings of provisional operating results on a consolidated basis, dated November 11, 2025 and August 11, 2025, showed Q1 2026 revenue of ₩31.0 billion, an operating loss of ₩1.7 billion and a net loss of ₩0.7 billion.
  • Earnings filings are interpreted more accurately by checking whether they point in the same direction as the annual trend and whether one-off factors are mixed in.
  • Whether the revenue recovery and narrowing losses continue in the next quarter's filing is the point to confirm.
🧭Bottom line
  • The strengths are that the top line has grown for three straight years and rose 22.9% again in Q1 as the upper layer of the business regains momentum, and that the company pairs a recognizable software base such as ALZip and ALYac with new AI and gaming ventures.
  • The share price has fallen 71% from its 52-week high, a level where expectations have already come down considerably.
  • On the other side, the company is still running an operating loss, so earnings-based measures like the P/E cannot be used, and a debt ratio of 391% leaves limited financial headroom.
  • In sum, if revenue growth outruns costs and turns into profit while the debt burden stays managed, today's lower share price could serve as a springboard for recovery; conversely, if the losses drag on or additional fundraising becomes necessary, the position could weaken.

MDS Tech9.65x0.56x5.82%
NuriFlex1.01x-9.23%
LS Tirauetec1.14x-12.04%

Within gaming and software, the peer set of publicly available data closest in market capitalization was looked at first. The current P/E (how many times one year's earnings the price represents) cannot be determined, and the P/B (how many times book value the price represents) is 1.77x. Because smaller-cap names are heavily affected by earnings swings and fundraising filings, no firm conclusion was drawn from last year's confirmed-results metrics alone. The basis for the forecast box is a DART seasonality approximation.

The latest close is ₩7,560 and the market capitalization is ₩88.9 billion. The price sits below its 20-day moving average (₩8,137) and below its 60-day moving average (₩11,354). 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 34.8, a neutral level. The one-month change is -23.4%, the three-month change is -38.5%, and the position relative to the 52-week high is -67.0%. Relative strength versus the KOSDAQ is 19 (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 18% of all stocks. Over the past three months it lagged the index by 19.8%.

Revenue rose 4.2% year over year (2023 ₩92.5 billion → 2024 ₩102.5 billion → 2025 ₩106.8 billion), and the three-year trend is 'rising'. That said, the pace of growth slowed from the prior year. Operating results are in the red, so a swing back to profit matters more than the growth rate here. Over the 5 years on record, revenue compound annual growth (CAGR) is 4.5%. The two-year revenue CAGR is 7.5%. In the most recent quarter (Q1 2026), revenue was 22.9% higher than the same period a year earlier.

What stands out

Points to watch

  • Debt far exceeds equity (debt ratio 391.4%).
  • The most recent full-year net result was a loss.
  • The most recent full year was a loss, so it is worth checking whether profitability recovers.
  • Revenue rose 4.2% year over year, and the pace is slowing (3-year trend: rising).

📖 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 (%).
