KC supplies equipment such as CMP and cleaning tools, along with materials like CMP slurry, to semiconductor and display fabs. The equipment side is order-driven, tied to when customers invest in new capacity, so quarterly revenue is lumpy, whereas materials tend to sell repeatedly once they are designed in. Capital-return moves continued through March, including a treasury-share cancellation on the 24th and a treasury-share disposal contract on the 25th. The Q1 2026 report filed on May 15 confirmed a slowdown, with both revenue and operating profit turning lower, and an ROE in the 5% range, below that of larger peers, partly explains the low multiples. The key point to watch: when the semiconductor capex cycle is alive and slurry-material sales support earnings, the discount can close quickly, but when customer investment is deferred and equipment orders thin out, quarterly volatility comes to the fore, so the next quarter's order flow and the direction of the memory market are central.

🔎 In-depth analysis
- KC supplies the equipment and materials that semiconductor and display fabs need.
- Its business runs along three lines.
- First is semiconductor equipment: it makes CMP tools that planarize circuit surfaces and wet-cleaning tools that wash surfaces, supplying memory makers such as Samsung Electronics and SK Hynix.
- Second is display equipment, where it makes panel-process tools such as wet stations, coater-and-track systems, and CO2 cleaners.
- Third is materials, supplying the abrasive used in the CMP process (CMP slurry) and nano-dispersion materials.
- Equipment is order-driven, with orders coming in when customers build new fabs or expand lines (capex), so quarterly revenue is lumpy; materials, by contrast, sell repeatedly once designed in, so that revenue is comparatively steady.
- The latest close is ₩27,950 and the market cap is ₩308.0 billion.
- The price sits below the 20-day line (₩31,318) and below the 60-day line (₩34,268).
- Trading below both its short- and mid-term moving averages, the trend is subdued.
- The RSI (an auxiliary gauge that weighs up-days against down-days over the past 14 days on a 0-100 scale) is 40.6, a neutral level.
- The one-month change is -5.6%, the three-month change is -5.9%, and the position versus the 52-week high is -30.5%.
- Relative strength versus the KOSPI is 32 (on a 1-99 scale that converts one-year return against the index with recent performance weighted more heavily; higher means stronger than the market).
- That places it around the top 68% of all stocks by strength.
- Over the past three months it has lagged the index by 27.6%.
- Chart readings are best considered alongside trading volume and disclosure dates.
- On confirmed FY2025 results, the P/E (price divided by one year of net profit) is 7.02x and the P/B (price divided by net assets) is 0.36x.
- A P/B below 1 means the market cap (₩322.9 billion) is smaller than the company's net assets (shareholders' equity of about ₩851.8 billion), a signal that the stock is priced below book value.
- Against a semiconductor equipment and materials peer set whose P/E ratios run broadly 24-217x and P/B 1.4-13x, KC's multiples sit noticeably low.
- ROE (the return earned on shareholders' equity in a year) is 5.1% and the operating margin is 5.8%, below the higher-tier peers (ROE 9-14%), but with a debt ratio of 135%, a current ratio of 353%, and an interest coverage ratio of 10.8x, its capacity to service debt is ample.
- Low trailing P/E and P/B in absolute terms need not be a burden in itself; indeed, for a company entering a recovery in earnings, it is closer to the real picture to weigh this year's expected earnings alongside last year's confirmed figure.
- Revenue jumped from ₩553.8 billion in 2021 to ₩858.0 billion in 2022, pulled back to ₩727.0 billion in 2023, then rose again to ₩738.5 billion in 2024 and ₩797.3 billion in 2025.
- Recent revenue is up 8.0% on the prior year, and the pace of increase is quickening, so the top line is once again trending higher.
- Operating profit rose 66.1% from ₩28.0 billion in 2024 to ₩46.5 billion in 2025, a clear recovery in profitability.
- The forward P/E computed on this revenue and earnings recovery sits below the peer-set average (about 35x) and even below the lowest-multiple peer, which can be read as a signal of undervaluation.
- This is possible because the memory market is reviving, lifting customer capex, while slurry materials, which generate repeat sales once designed in, support the earnings floor.
- That said, the most recent quarter, Q1 2026, slowed, with revenue of ₩212.5 billion (-10.2%) and operating profit of ₩14.0 billion (-45.3%).
- Given that equipment revenue swings quarter to quarter with order timing, it is too early to judge the full-year trend from a single quarter, but whether this slowdown persists needs to be confirmed in the next quarter's results.
- The disclosure flow shows capital return and earnings shifts together.
- On March 24, 2026, a treasury-share cancellation coincided with a trading suspension on part of the held shares, and on March 25 the company disclosed a treasury-share disposal contract, continuing its use of treasury stock.
- On April 7, changes in the holdings of the largest shareholder and others, along with a large-holdings report, offered a look at governance and stake shifts.
- The Q1 2026 report (filed May 15) is the confirmed document capturing the first-quarter slowdown, and a semi-annual review-related disclosure followed on June 1.
- All source texts can be checked directly in the disclosures.
- KC's strengths are clear, augmented by capital-return moves such as treasury-share cancellation and disposal.
- At the same time, the cautions deserve an honest look.
- A large part of equipment revenue hinges on the timing of customer capex, making quarterly results lumpy, and indeed Q1 2026 revenue and operating profit both turned lower.
- An ROE in the 5% range, below the higher-tier peers, also partly explains the low multiples.
- In sum, this is a stock positioned where the discount can close quickly when the semiconductor capex cycle is alive and slurry-material sales support earnings, but where quarterly volatility can come to the fore when customer investment is deferred and equipment orders thin out.
- The crux dividing those two paths is the next quarter's orders and the direction of the memory market.
🔎 Valuation vs peers Inconclusive
Aligned with KC's actual business (semiconductor and display process equipment and CMP slurry materials), listed companies in the semiconductor equipment and materials field were chosen as the peer set, with the base-industry sample (medical, precision, and optical instruments) used only as a secondary reference since its business character differs.
| Peer | P/E | P/B | ROE |
|---|---|---|---|
| Jusung Engineering | 208.36x | 12.60x | 6.05% |
| TCK (Tokai Carbon Korea) | 36.14x | 4.87x | 13.46% |
| Dongjin Semichem | 22.17x | 2.03x | 9.14% |
| CIS | 20.28x | 1.15x | 5.66% |
On peer-set position alone, KC's P/E of 8.4x and P/B of 0.43x rank among the lowest in the semiconductor equipment and materials group. These low readings, however, appear to reflect both (a) profitability that is only about half that of peers (ROE in the 5% range) and (b) a business whose quarterly earnings swing widely with customer investment. Even if the trailing P/E on last year's confirmed earnings is low, given that Q1 2026 operating profit fell -45%, it is hard to assume this year's earnings will hold at last year's level. The cheap position versus peers is clear, but with earnings at an inflection point, we leave it Inconclusive rather than deeming it undervalued.

Price history Close · MA20 · MA60
The latest close is ₩27,950 and the market capitalization is ₩308.0 billion. The price sits below its 20-day moving average (₩31,318) and below its 60-day moving average (₩34,268). 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 40.6, a neutral level. The one-month change is -5.6%, the three-month change is -5.9%, and the position relative to the 52-week high is -30.5%. Relative strength versus the KOSPI is 32 (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 32% of all stocks. Over the past three months it lagged the index by 27.6%. 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 7.02x is below the sector median (22.72x). The P/B of 0.36x is below the sector median (1.61x). Both metrics are low versus peers, so the price is not expensive relative to earnings and assets.
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.
Profitability & financials
Return on equity (ROE) is 5.1%, in line with the sector average (5.0%). The operating margin is 5.8%. The debt ratio is 135.4%, so the financial structure is moderate.

📖 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 (%).
