KC Tech Overview
KCTECH is the only Korean company that develops and mass-produces both chemical-mechanical planarization (CMP) equipment and the CMP slurries those tools consume. That combination gives it a hardware-plus-consumables model closer to the global equipment leaders than to most single-product Korean suppliers. In FY2025 the semiconductor business supplied about 90% of revenue: CMP polishers, wafer wet-cleaning systems, and dielectric (ceria/silica) and metal slurries. Its core customers are Samsung Electronics and SK hynix. Display equipment (wet stations, coaters, track systems) is now a shrinking legacy business. The company is debt-free with a net cash balance sheet. It is run under the control of the founding Ko family through KC Co., Ltd. Its growth case rests on more CMP steps per wafer in advanced DRAM, HBM and 3D NAND; on Korean chipmakers localising imported slurry; and on new uses for planarization in advanced packaging (hybrid bonding, glass-core substrates, build-up films). Its main exposures are the memory-capex cycle and heavy dependence on two customers.
What the company does
KCTECH designs, manufactures and sells front-end process equipment and process consumables for semiconductor and flat-panel-display fabs. The FY2025 business report groups its activities into two reportable segments: a Semiconductor segment (CMP equipment, wet-cleaning equipment and CMP slurry/nano-dispersion materials) and a Display segment (wet stations, coaters, track systems and related materials for OLED/LCD lines).
The company describes its offering in three product families:
Semiconductor equipment: CMP systems and wet-cleaning systems.
Display equipment: wet stations, coaters and track systems.
Materials: CMP slurries (dielectric slurry and additives, metal slurry) and nano-dispersions.
Business and revenue model
| Revenue stream | Nature | Characteristics |
|---|---|---|
| CMP equipment | Capital equipment, one-time sale per tool | Lumpy and tied to Samsung/SK hynix fab build-outs; recognised on delivery and acceptance; large single orders (e.g. KRW 69.8 bn from SK hynix in March 2026) |
| Wet-cleaning equipment | Capital equipment | Same timing as fab expansions; a new family of cleaning tools is a 2026–27 growth lever |
| CMP slurry and nano-dispersion | Consumable, recurring | Volume moves with wafer starts and fab utilisation rather than capex; higher-margin and more stable |
| Display equipment | Capital equipment | Tied to OLED/LCD capex in Korea and China; in structural decline |
| Parts, service and upgrades | Aftermarket | Not reported separately |

Broker estimates put the semiconductor mix at about 60% equipment and 40% slurry. The company sells products and has no subscription or licensing revenue.
Value-chain position and customers
KCTECH is a tier-1 supplier to wafer fabs. Its customers are integrated device makers, chiefly memory makers Samsung Electronics and SK hynix. In 2025 the company said it also works with several global foundry companies, including Intel, on next-generation materials development. It reported about 25 joint development projects in progress with Samsung and about 15 with SK hynix. End-markets are DRAM (including HBM), NAND, logic/foundry, and OLED/LCD panels.
Independent characterisation
In practice KCTECH is a Korean localisation champion inside a CMP oligopoly. In equipment it is a distant third to Applied Materials, which holds more than 60% of the global CMP tool market, and Ebara. It wins share mainly inside Korean fabs, where customers value a domestic second source. In slurry its ceria-based dielectric slurry is built on its own technology, and Samsung recognised it in April 2026 for replacing imported materials. Selling both the tool and the slurry lets KCTECH co-optimise them for one customer, which is a real but narrow advantage. Earnings power swings with Korean memory capex. Slurry gives it a floor that pure equipment peers lack.
Strategy
KCTECH's stated strategy rests on four themes:
-
Customer-centric co-development with a few large customers, with tools and slurry designed together for each customer's process (about 25 joint projects with Samsung and 15 with SK hynix in 2025).
-
Localisation: replacing imported CMP tools and slurries in Korean fabs, as recognised by Samsung's April 2026 award.
-
Next-generation CMP platform: VENTUS, aimed at new DRAM, HBM and NAND lines, with qualification at Samsung under way.
-
Moving into advanced packaging: applying front-end CMP expertise to hybrid bonding, glass-core panel-level substrates and build-up films (BuF). In 2026 the company is taking part in government R&D on build-up film, polymer planarization and low-loss dielectric layers.

Financial Narrative
Income statement
FY2025 gross profit was KRW 382.9 bn of revenue and about KRW 60.2 bn of EBIT. FY2025 EPS was about KRW 2,604. The dividend for FY2025 was KRW 450 per share, with an ex-dividend date of 26 February 2026 and a payout ratio of about 11.6%. Revenue CAGR from FY2021 to FY2025 was 2.7%, which hides a full cycle: a peak in 2022, a 24% fall in 2023, and a return to record revenue in 2024–25.
Quarterly trajectory
Nine-month 2026 revenue reached KRW 383.0 bn, already equal to all of FY2025. Nine-month operating profit was KRW 78.5 bn (+80% on 9M25's KRW 38.3 bn) and net income was KRW 80.5 bn. The 1Q26 peak reflects delivery of the large SK hynix tool order. 3Q26 revenue and operating profit came in about 29% and 42% below consensus, which is typical of how lumpy tool revenue is.
Balance sheet and ratios
KCTECH has had almost no interest-bearing debt since the spin-off. Brokers have shown debt at about 0.5% of capital since 2018, and interest coverage is effectively unlimited. Most liquidity is held in short-term financial instruments rather than cash. Capital spending is light: KRW 7–13 bn a year from 2017 to 2020. Equipment makers carry receivables and inventory, so working capital swings with tool deliveries, and operating cash flow is lumpier than earnings.
Commentary
2021–22 upcycle: Samsung's P3 and SK hynix's M16 build-outs, plus tool localisation at foundry and W-CMP customers, drove record profit in 2022 (operating margin 15.9%). Slurry volumes grew alongside.
2023 downturn: Memory makers cut capex. Revenue fell 24% and operating margin dropped to 11.4%. Gross margin held at 34%, showing how slurry cushions a downturn.
2024 recovery: Tool deliveries clustered in 4Q24 (KRW 144.9 bn of revenue in the quarter), and Samsung Display orders added to revenue.
2025 mix shift: Display revenue halved while semiconductor revenue grew about 12%. Total revenue was flat, but operating profit rose 20.5% to KRW 60.0 bn as the mix moved toward higher-margin semiconductor products and slurry.
2026 inflection: DRAM 1c-node and HBM4 capacity additions drove 1Q26 record results. Nine-month operating margin of 20.5% is the highest since the spin-off.

Analyst Conclusions
Guidance and consensus
Kiwoom (Nov 2025): 2026E revenue (KRW bn): 422.3; 2026E operating profit (KRW bn): 69.4; 2027E operating profit (KRW bn): —
Independent research (Apr 2026): 2026E revenue (KRW bn): 430.0; 2026E operating profit (KRW bn): 70.0; 2027E operating profit (KRW bn): 82.5
Broker update (Jul 2026): 2026E revenue (KRW bn): —; 2026E operating profit (KRW bn): 146.2; 2027E operating profit (KRW bn): 201.1
Nine-month 2026 operating profit of KRW 78.5 bn already exceeds the late-2025 full-year forecasts. Meeting the July 2026 estimate of KRW 146.2 bn would need about KRW 68 bn of operating profit in 4Q26, which looks stretched after 3Q26's KRW 20.2 bn. Management does not give formal guidance.
Bull case
-
Memory capex keeps rising into 2027 as new DRAM fabs complete and AI inference expands, and CMP steps per wafer increase.
-
VENTUS qualifies at Samsung and gains share, with matching slurry pull-through.
-
Packaging CMP (glass core, hybrid bonding) and the US subsidiary diversify the customer base.
Bear case
-
3Q26's consensus miss shows how lumpy tool revenue is, and full-year expectations may be too high.
-
Valuation already reflects the cycle, and the shares fell about 25% in a single month in 2026.
-
Two-customer dependence, family control and the 2026 disclosure sanction limit the valuation multiple.

Analyst verdict. KCTECH has turned from a cyclical mid-cap into an earnings-momentum story. The business is real: no debt, a slurry base that held 34% gross margins through the 2023 downturn, and a domestic monopoly on integrated CMP tools and slurry that Samsung publicly rewarded in 2026. Nine-month 2026 results show the operating leverage clearly. Revenue has already matched all of 2025, and operating margin is above 20% for the first time since the 2017 spin-off. The structural case — more planarization steps per HBM stack and per advanced DRAM node, and planarization moving into packaging — is credible and fits management's investment in VENTUS, glass-core systems and a US subsidiary.
The risks are as clear. Two customers and their capex calendars set the company's revenue. The 3Q26 miss shows that one delayed tool can wipe out a quarter's expected profit. The display business is no longer a meaningful offset. Governance — family control of about 54.5%, succession-driven share transfers and the January 2026 disclosure sanction — will keep the stock at a discount to global peers, however strong its earnings. After a roughly threefold rise in a year, the shares already price in much of the cycle.
On balance KCTECH is a high-quality, high-beta way to play Korean memory capex. Two things would sustain a re-rating: winning VENTUS qualification at Samsung and showing the first customers outside Korea or outside memory. Without them, results will keep tracking Samsung's and SK hynix's order timing, and investors should expect sharp swings around a rising earnings trend.
