Hmnex

HMNEX is a KOSDAQ-listed company founded in 1993 that has changed its corporate name several times, moving through Lasemtech, CTL, Citizen, Live Financial, and Cloud Air before adopting its current name in April 2025.

Its core business since 2002 has been manufacturing automotive LED packages, supplying LED lighting modules used in Hyundai and Kia instrument clusters, audio units, and ambient lighting to tier-1 and tier-2 parts suppliers.

Major customers include Hyundai Mobis, Korea Alps, Inex, Mobase Electronics, Yoonjin Electronics, and Suhbeon, which are tier-1 and tier-2 automotive parts manufacturers.

The company has secured entry barriers into the finished-vehicle supply chain by obtaining the top-grade SQ certification and IATF 16949 certification from Hyundai and Kia.

In 2025 the company acquired a 100% stake in semiconductor equipment specialist SMI, bringing it into the consolidated group and marking its new entry into the semiconductor equipment and materials business.

SMI supplies deposition-process LDS (liquid delivery system) equipment to SK Hynix in addition to having domestically developed an optical temperature sensor for etching processes.

The optical sensor market had previously been dominated by foreign firms such as US-based Luxtron, which is why the localization effort drew market attention.

As a result, the company is pursuing a transformation into a comprehensive advanced-equipment maker by combining the stable cash flow of its automotive lighting business with its subsidiary's semiconductor equipment capabilities.

2025 consolidated revenue reached KRW 31.7bn, more than double 2024's KRW 15.2bn, while operating profit expanded sharply to KRW 2.4bn (7.5% operating margin) from roughly KRW 0.3bn in 2024.

Operating margin gradually improved from -8.0% in 2022 to 0.1% in 2023 and 2.1% in 2024, before jumping to 7.5% in 2025, marking a clear turnaround from loss to profit.

Net income attributable to owners fluctuated but trended broadly higher, from KRW 4.2bn in 2022 to KRW 8.2bn in 2023, KRW 5.5bn in 2024, and KRW 11.0bn in 2025.

By quarter, revenue was KRW 11.3bn with operating profit of KRW 1.3bn in 3Q25, KRW 11.8bn revenue with KRW 0.9bn operating profit in 4Q25, KRW 11.6bn revenue with KRW 0.9bn operating profit in 1Q26, and KRW 13.4bn revenue with KRW 1.4bn operating profit in 2Q26, showing a continued upward trend in both revenue and operating profit.

Owners' net income, however, moved in the opposite direction, falling from KRW 3.5bn in 3Q25 and KRW 3.9bn in 4Q25 to KRW 2.7bn in 1Q26 and KRW 1.3bn in 2Q26.

This divergence is interpreted as reflecting non-operating swings tied to the early stage of the semiconductor equipment subsidiary's consolidation; past results have included one-off non-operating gains, such as operating income generated from fully recovering the KRW 48bn principal invested in the Kansers Signature Shipping Fund.

On the balance sheet side, the debt ratio rose from 2.4% in 2022 to 20.7% in 2025, a result attributed to expanded investment including the SMI acquisition and the Yongin site purchase.

Operating cash flow swung from a net inflow of KRW 1.9bn in 2024 to a net outflow of KRW 0.5bn in 2025, suggesting that actual cash generation warrants scrutiny alongside topline growth.

Analysts note that the memory semiconductor market continues to grow on rising demand driven by AI and big data proliferation.

There is also a view that as semiconductor capital expenditure expands, centered on the US and China, and as process miniaturization and 3D structuring progress, the importance of related process equipment is increasing.

The market for ultra-precision measurement components such as optical temperature sensors has long been dominated by foreign firms such as US-based Luxtron, making domestic entry relatively rare.

The semiconductor cluster being built around Yongin and Pyeongtaek is regarded as the world's largest semiconductor mega-cluster, with roughly KRW 1,000tn in planned private investment centered on SK Hynix and Samsung Electronics.

SK Hynix's first fab in the cluster targets an operational start in 2027, meaning actual revenue contribution for equipment and parts suppliers there is likely to lag with a time gap.

In terms of competitive landscape, SMI's cited potential customer base spans SK Hynix, Samsung Electronics, Micron (Japan, US, Taiwan), TSMC, and China's CXMT among other global memory and foundry companies.

In the LED segment, the company appears to have continued expanding supply by participating in Hyundai and Kia's follow-on model development, a typical growth path within a domestic auto parts ecosystem heavily dependent on the two automakers.

The company has stated that it expects to supply more than 10% of monthly optical temperature sensor usage at Micron's Singapore plant starting in 2026, expanding to roughly 50–60% from 2027 onward. Actual order intake is expected by the company to begin arriving progressively from the first quarter of 2026.

The Yongin semiconductor cluster industrial site (11,252 m²) was decided for acquisition in March 2026 for KRW 14.8bn, equivalent to 11.86% of the company's assets.

The site is adjacent to fab facilities SK Hynix is building with a planned investment of KRW 600tn, and the company has stated a plan to use this location to strengthen partnerships with global chipmakers.

However, the site purchase price and future capex are planned to be funded through parent-company capital increases and equity participation, leaving the financing plan's finalization as a parallel task.

The LED segment maintains its policy of continuously expanding supply by participating in Hyundai and Kia's follow-on mass-production model development. SMI has set a goal of using its Micron Singapore foothold to expand its supply chain toward SK Hynix, Samsung Electronics, and TSMC.
