Cymechs

Founded in 2005 and listed on KOSDAQ in 2015, Cymechs specializes in automated wafer-transfer equipment for semiconductor manufacturing.

Its core products include the Equipment Front End Module (EFEM), Load Port Module (LPM), ATM robots, VTM robots, and Transfer Chambers, which allow wafers to move safely and precisely between process tools.

The company is the sole domestic firm to have localized high-vacuum wafer-transfer robot technology in 2007, and its supply chain now includes not only Samsung Electronics and SK hynix but also TSMC, Micron, and Hitachi.

Its first-tier customers are equipment makers such as Semes, Wonik IPS, and Applied Materials, through which its equipment ultimately reaches Samsung Electronics' and SK hynix's fabs.

As of last year (2025), revenue by customer was roughly split as Semes 40%, Wonik IPS 20%, Applied Materials 10%, and others 30%, while front-end processes accounted for about 85% of revenue versus 15% for back-end.

In the front end, Cymechs has been designated as Samsung Electronics' standardized EFEM supplier, giving it a high share of related volume. In the back end, it supplies wafer-transfer equipment to TC-bonder makers such as Hanmi Semiconductor, ASMPT, and Semes, placing it within the HBM value chain as well.

More recently, the company completed development of glass-substrate transfer equipment and is preparing deliveries to customers, extending its business into front-end, back-end, and next-generation packaging equipment.

Domestic peers include Robostar and Rotem Systems, while overseas the competitive field includes Japan's TDK and the United States' Brooks Automation.

Consolidated revenue in 2025 came to KRW 164.4 billion, essentially flat versus 2024's KRW 165.1 billion, with operating profit of KRW 23.3 billion (14.2% operating margin), matching the prior year's margin.

In 2023, revenue fell to KRW 156.6 billion and operating profit dropped sharply to KRW 7.1 billion (4.5% margin), but margins recovered quickly in 2024 to KRW 165.1 billion in revenue and KRW 23.4 billion in operating profit (14.2%).

In 2022, revenue was KRW 195.1 billion and operating profit KRW 21.2 billion (10.8% margin), meaning the operating margin swung from 10.8% to 4.5% to 14.2% to 14.2% over the past four years.

Net income attributable to owners rose from KRW 7.6 billion in 2022 to KRW 11.0 billion in 2023 and KRW 15.4 billion in 2024, before edging down to KRW 14.9 billion in 2025.

On a quarterly basis, revenue and profit declined for three straight quarters from Q2 2025 (KRW 48.3 billion revenue, KRW 7.4 billion operating profit) to Q3 2025 (KRW 41.2 billion, KRW 6.2 billion) and Q4 2025 (KRW 29.1 billion, KRW 2.3 billion), with a net loss attributable to owners of KRW 0.4 billion in the fourth quarter.

In the first quarter of 2026, revenue was KRW 40.5 billion and operating profit KRW 4.7 billion, signaling a pass through the trough, and by the second quarter revenue reached KRW 62.5 billion with operating profit of KRW 11.3 billion, the highest levels of the trailing five quarters.

This pattern aligns with brokerage commentary that equipment deliveries deferred from the fourth quarter of 2025 were recognized in the first quarter of 2026, with full-year results expected to build from a first-quarter trough.

Over the trailing four quarters (Q3 2025 through Q2 2026), net income attributable to owners totaled KRW 16.7 billion, as the strength of the first and second quarters of 2026 offset much of the fourth-quarter 2025 weakness.

The semiconductor equipment industry is driven by memory makers' capital spending cycles; clean-room space constraints kept back-end investment as the priority through 2025, but front-end investment tied to new clean rooms has been gaining momentum in 2026.

Samsung Electronics is understood to be pursuing DRAM conversion investment at its P4 line, SK hynix at M15X, and Micron at Fab16. In the HBM market, SK hynix held a leading 62% share as of the second quarter of 2025, followed by Micron at 21% and Samsung Electronics at 17%.

However, Samsung Electronics began regaining share from the fourth quarter of 2025 and reclaimed the top position in the overall DRAM market in the first quarter of 2026, with its HBM share estimated to have risen to around 30%.

SK hynix began mass shipment of HBM4 in the second quarter of 2026 and stated it would scale up production significantly in the second half. AMD has reportedly designated Samsung Electronics as its primary supplier for next-generation HBM4, signaling potential shifts in the HBM supply chain.

The concurrent expansion of Samsung's front-end reinvestment and both companies' HBM back-end volumes structurally increases Cymechs' exposure, given its presence across both value chains.

Competitively, domestic peers such as Robostar and Rotem Systems and overseas players including TDK and Brooks Automation compete in the wafer-transfer equipment market.

In a report dated March 20, 2026, SK Securities projected that a core-business recovery from Samsung Electronics' front-end investment and an increase in back-end results from expanded HBM investment would appear simultaneously.

The report presented a 2026 revenue estimate of KRW 211.0 billion, up 34.7% year over year, and an operating profit estimate of KRW 26.4 billion, up 271.3%.

The drivers cited included growth in back-end wafer-transfer equipment sales tied to expanded HBM investment, along with the effect of excluding the prior year's operating loss at subsidiary Shindo E&C from consolidated results.

The report also noted that localization of the ATM robot, which accounts for about 10% of wafer-transfer equipment cost, has been completed and is being internalized, which was cited as a further profitability driver.

As a new business line, the company has completed development of glass-substrate transfer equipment and is preparing deliveries to customers, extending its reach into next-generation packaging revenue.

That said, these projections depend on the actual pace of customer capital deployment, including Samsung's subsequent P4 phases (Ph2, Ph3, Ph4), SK hynix's M15X investment, and the timing of HBM4 orders.

No official annual revenue or profit guidance from the company itself has been confirmed, and the projections above are based on individual brokerage research rather than company disclosure.
