Yunsung F&C is a machinery and equipment company that designs, builds, and delivers production-process automation equipment and systems installed when a customer builds a new plant or expands a line; its revenue swings heavily with the size and delivery schedule of whatever supply contracts it wins, and with a market cap of ₩131.3 billion, one large contract has a relatively big impact. It signed supply contracts in quick succession — ₩49.7 billion in May 2026 (49.6% of recent revenue) and ₩37.5 billion in December 2025 (12.0%) — and Q1 2026 showed a swing to net profit. What stands out recently is that the asset-based undervaluation at a P/B of 0.74x and new orders equal to about half of annual revenue are threads of recovery; however, the 2025 annual loss and revenue plunge still linger in the results, so the pace at which new orders convert into revenue and profit on schedule must be checked quarter to quarter.

Core valuation metric

Forward P/E (expected earnings)

This stock's effective sub-sector is “Battery Equipment” (Secondary Batteries · Battery Materials, Parts & Equipment), a type typically read first through forward P/E.

Battery equipment makers hinge on the capacity expansions of cell producers, so profit swings widely between order-rich and order-lean years. Because booked orders turn into future revenue and earnings, forward price-to-earnings (P/E on expected profit) is the first lens rather than trailing results.

P/B (price-to-book)0.83x

Price against earnings alone becomes unstable when earnings swing. Reading it together with price against assets helps gauge the downside.

That said, earnings are swinging with the industry cycle right now, so this metric is best viewed alongside asset value and the demand backdrop.

🔎 In-depth analysis Reading

🏢Business

Yunsung F&C is a machinery and equipment company that designs, builds, and delivers automation equipment and systems used in production processes. Because it wins orders and builds the equipment installed when a customer builds a new plant or expands a line, its revenue swings heavily with the size and delivery schedule of whatever supply contracts it wins at the time. Its practical site classification is also machinery and equipment. With a market cap of ₩131.3 billion, on the smaller side, a single large contract coming in or dropping out has a relatively big effect on revenue and results.

📈Price & chart

The latest close is ₩18,450 and the market capitalization is ₩147.2 billion. The price sits above its 20-day moving average (₩15,483) and below its 60-day moving average (₩20,670). Short-term and medium-term trends are diverging, so the direction is best read separately. The RSI (a supplementary indicator that gauges the strength of gains versus losses over the past 14 days on a 0-100 scale) is 55.7, a neutral level. The one-month change is +11.8%, the three-month change is -47.9%, and the position relative to the 52-week high is -56.3%. Relative strength versus the KOSDAQ is 20 (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 19% of all stocks. Over the past three months it lagged the index by 20.0%. Chart interpretation is best done alongside trading volume and the dates on which disclosures occur.

📊Key metrics

Recent annual (2025) revenue is ₩100.2 billion, operating profit -₩31.6 billion, and net profit -₩19.2 billion, a loss. The operating margin of -31.6% and ROE (how much is earned on equity in a year) of -10.8% are negative, and the debt ratio (debt against equity) is 150.9%. That said, the current ratio (assets convertible to cash within a year against debt due within a year) is 190.1%, so short-term payment ability has room, and on this reading financial soundness is registered as 'average.' Because earnings are in the red, the P/E (how many times a year's earnings the price reflects) is not calculated; instead, the P/B (how many times book value the price reflects) is 0.83x. That means market cap is lower than the company's net assets — a cheap range on asset value. There is no reason to view a P/B below 1x as a 'burden'; it is better read as leaving room for re-valuation once the loss passes and earnings normalize.

🚀Growth

Revenue fell sharply from ₩312.9 billion in 2023 and ₩271.3 billion in 2024 to ₩100.2 billion in 2025 (a two-year declining trend). As the customer investment cycle cooled, new orders and deliveries fell together, and the loss over this stretch also came from that demand contraction. Still, the recent flow holds clues that could change direction. Q1 2026 revenue of ₩21.9 billion was down 26.5% from a year earlier, but the rate of decline eased versus before, and net profit swung positive at ₩1.0 billion. On top of this, supply contracts of ₩37.5 billion in December 2025 and ₩49.7 billion in May 2026 were secured in succession, and the ₩49.7 billion is a large deal equal to about half of recent annual revenue. If these contracts are recognized as delivery and revenue on schedule, they become the engine to refill the shrunken revenue base. This year's revenue estimate of ₩72.6 billion combines the confirmed Q1 2026 results with past quarterly weightings, and the actual outcome could come in higher or lower depending on when the new orders are delivered. This company's growth depends less on a fixed trend line than on the speed at which its order backlog converts into revenue.

📰Recent news & filings

Recent disclosures are all order-related. The May 13, 2026 supply contract (₩49.7 billion, 49.6% of recent revenue) and the December 29, 2025 supply contract (₩37.5 billion, 12.0% of recent revenue) are large enough to be the key variables for future revenue recognition. On May 15, 2026, a corrected disclosure related to an earlier contract was issued; confirming from the original text the contract amount, delivery period, and whether it is a one-off or a repeatable transaction is what determines the medium-term interpretation. It is best to track in the next quarter's results whether the orders actually flow through to revenue and profit.

🧭Bottom line

This is a stock with distinct strengths and weaknesses. There are two strengths: first, the price has fallen to 0.74x book value, a cheap spot on asset value; and second, the Q1 2026 swing to net profit and new orders equal to about half of annual revenue register as threads of recovery. The weakness is that the 2025 annual loss and revenue plunge still linger in the results; the flow of climbing out of losses must be confirmed in quarterly results before the asset-based undervaluation carries through to an earnings-based one. In sum, if the newly won orders convert into revenue and profit on schedule, the current low P/B becomes a springboard for re-valuation; conversely, if delivery of the orders is delayed or further orders dry up, the loss phase could lengthen. The key is the speed at which the order backlog turns into results, and this can be checked quarter to quarter.

Within machinery and equipment, we prioritized public-data peers close in market cap. The current P/E (how many times a year's earnings the price reflects) is not available, and the P/B (how many times book value the price reflects) is 0.83x. That said, for smaller-cap names, earnings swings and financing disclosures carry a large impact, so we did not draw a firm conclusion from last year's confirmed-results metrics alone. The basis for the outlook box is a DART seasonality approximation.

📖 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 (%).
