Prune Savings Bank is a savings bank under the Mutual Savings Banks Act, raising funds through deposits and deploying them into loans, placements, and securities, so its core earnings source is the spread between deposit interest and investment income. In 2025, as loan-loss provisions fell and gains on the valuation and disposal of securities rose, operating profit of ₩16.9 billion and net profit of ₩19.9 billion marked a sharp earnings recovery from the prior year, and in April the company put forward a corporate value-up plan. What stands out lately is that a P/B of 0.47x—below book value—together with an ROE above peers and a generous 45.4% payout ratio make it attractive from a value and dividend standpoint, but because the earnings recovery mixes in volatile items such as provision reversals and securities gains and losses, a single quarter can turn to a loss as in Q1, and the durability of earnings needs to be checked quarter by quarter.

- For financial companies, debt and interest costs are large by the nature of the business, so the debt ratio and interest coverage cannot be read on the same yardstick as an ordinary company.
- ROE is 6.2% (total-net basis). It is above the sector average.
- The P/E sits below the sector median.

🔎 In-depth analysis
- Prune Savings Bank is a savings bank under the Mutual Savings Banks Act.
- Its earnings structure is simple.
- It takes deposits from customers to raise funds (its main funding source is deposits), then lends that money out, places it with other financial institutions, and invests it in securities to earn interest and investment income.
- In other words, the core earnings source is the difference between deposit interest (cost) and loan and investment income (revenue).
- In 2025 net profit improved as loan-loss provisions (a cost set aside in advance against expected defaults) fell and gains on the valuation and disposal of securities held rose.
- Since its market capitalization is not large, it is worth watching not only the business itself but also the effect a single filing on provisions or funding can have on results and share count.
- The latest close is ₩10,290 and market capitalization is ₩155.2 billion.
- The price sits below the 20-day line (₩10,306) and below the 60-day line (₩10,793).
- Trading under both its short- and medium-term moving averages, the trend is on the soft side.
- The RSI (a supplementary gauge that weighs the strength of gains against losses over the past 14 days on a 0–100 scale) is 46.0, a neutral level.
- The one-month change is +2.2%, the three-month change is -9.7%, and the position versus the 52-week high is -23.7%.
- Relative strength against the KOSDAQ is 79 (1–99, converted from return versus 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 20% of all stocks by strength.
- Over the past three months it led the index by 23.9%.
- Chart reading is best done alongside trading volume and the dates on which filings occurred.
- The P/E is 7.81x and the P/B is 0.48x.
- A P/B below 1x means the price is set even below the company's book shareholders' equity, and the P/E is also below the peer median, so the diagnosis flags it as undervalued.
- Profitability is at an ordinary level, with an ROE of 6.2% that runs above the peer average, and the payout ratio is 45.4%, returning a substantial share of earnings to shareholders.
- The debt ratio is 486%, which looks high on the number alone, but for a bank that takes deposits and deploys them, those deposits are booked as liabilities in accounting terms, so its risk cannot be judged by the same yardstick as a typical manufacturer.
- In this industry, the thickness of capital and the adequacy of provisions matter more than the absolute level of the debt ratio.
- The annual earnings flow stands out as being in a recovery phase.
- Operating profit went from ₩9.0 billion in 2023 to ₩6.8 billion in 2024 to ₩16.9 billion in 2025, up about 147% year on year in 2025.
- Net profit also rose about 183%, from ₩7.0 billion in 2024 to ₩19.9 billion in 2025.
- Behind the increase, as noted above, are a lighter loan-loss provision burden plus gains on the valuation and disposal of securities.
- That said, the company does not put out an official outlook, so there is no basis to pin down this year's earnings in advance.
- In fact, on a cumulative Q1 2026 basis it was temporarily in a loss with operating profit of -₩4.0 billion and net profit of -₩0.8 billion, which fits the nature of savings-bank earnings, where provisions and securities gains and losses swing from quarter to quarter.
- So the growth picture is best read by holding together the confirmed fact that earnings recovered sharply in 2025 and the point that quarterly earnings are highly volatile.
- Most recently, on 2026-04-08, a corporate value-up plan (voluntary disclosure) was released.
- As a document in which the company itself lays out the direction of shareholder returns and corporate value, it offers a clue to the direction of dividend and capital policy.
- Earlier, on 2026-03-25 and 2026-03-11, filings on a change of 30% or more in profit/loss (15% for large corporations), including corrections, were released, confirming that 2025 earnings rose sharply year on year with operating profit of ₩16.9 billion and net profit of ₩19.9 billion.
- The judgment firms up when one also considers whether the earnings recovery the filings point to came from one-off factors (such as securities disposals) or is a flow that continues into the next quarter.
- The strengths are clear.
- With a P/B of 0.47x below book value and a P/E below peers, it is in an undervalued range; ROE runs above the peer average; and shareholder returns are generous, with a 45.4% payout ratio and a high dividend yield.
- The sharp 2025 earnings recovery and the company's own release of a corporate value-up plan are also favorable.
- On the other side, the point to watch is earnings volatility.
- The recovery mixes in items that swing widely, such as provision reversals and securities gains and losses, so a single quarter can turn to a loss, as in Q1 2026.
- And with a small market capitalization, a single filing on funding or provisions has a relatively large effect.
- In short, this is a stock with clear appeal from a value and dividend standpoint—approached for its cheap price versus assets and earnings and its dividend—that comes with the character of swinging quarterly earnings and a need to check the durability of earnings quarter by quarter.
🔎 Valuation vs peers Undervalued
A set of banks with market capitalizations near Prune Savings Bank's.
| Peer | P/E | P/B | ROE |
|---|---|---|---|
| Jeju Bank | 25.48x | 0.55x | 2.15% |
| Industrial Bank of Korea | 6.03x | 0.45x | 7.44% |
Within banks, public-data peers with nearby market capitalizations were looked at first. The current P/E is 7.81x and the P/B is 0.48x. That said, smaller-cap names are heavily affected by earnings swings and funding-related filings, so no conclusion was drawn from last year's confirmed-results metrics alone. For the outlook box, an official company outlook could not be confirmed.
Price history Close · MA20 · MA60
The latest close is ₩10,290 and the market capitalization is ₩155.2 billion. The price sits below its 20-day moving average (₩10,306) and below its 60-day moving average (₩10,793). 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 46.0, a neutral level. The one-month change is +2.2%, the three-month change is -9.7%, and the position relative to the 52-week high is -23.7%. Relative strength versus the KOSDAQ is 79 (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 80% of all stocks. Over the past three months it outpaced the index by 23.9%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.

Key metrics vs whole-market median
Valuation
The P/E of 7.81x is below the whole-market median (13.81x). The P/B of 0.48x is below the whole-market median (1.15x). Both metrics are low versus peers, so the price is not expensive relative to earnings and assets.
Profitability & financials
Return on equity (ROE) is 6.2%, above the whole-market average (5.0%). The debt ratio is 486.0%, but for financial firms deposits and insurance liabilities count as debt, so it cannot be read on the same yardstick as an ordinary company.

📖 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 (%).
