Business structure

Luken Technologies, established in October 2007, is a specialist manufacturer of display and semiconductor inspection equipment and components headquartered in Yongin, Gyeonggi Province, where it owns a facility of approximately 5,400 pyeong (roughly 17,900 sqm).

More than 50% of its approximately 120 employees are R&D personnel, and the company operates a precision manufacturing system certified to ISO 9001 and ISO 14001.

The business is divided into two principal segments: display inspection equipment and consumable parts, and semiconductor inspection consumable parts—with the display segment primarily supplying LCD and OLED panel inspection equipment and Probe Units to LG Display and other major panel makers.

The semiconductor segment encompasses M-POGO Vertical Probe Cards, M-POGO Test Sockets, Test Interface Units (TIU), and connectors, all leveraging M-POGO Pins produced in-house at the company's proprietary MEMS Fab.

The April 2024 acquisition of ISC's TIU unit established a vertically integrated chain spanning inspection equipment, interface boards, and test sockets; the re-absorption of subsidiary ITMTC in 2025 further consolidated manufacturing capabilities and reinforced cost competitiveness.

The inspection parts revenue mix rose to approximately 35% of consolidated sales in 2024, with the company targeting a combined display and semiconductor consumable parts share exceeding 50% by end-2025.

In the competitive landscape, sector leaders Leeno Industrial and ISC each command several hundred billion KRW in annual revenues with established global customer relationships, whereas Luken is at the early stage of scaling its semiconductor parts business, leaving a significant scale gap.

The global market for semiconductor test interposers has been dominated by Japanese suppliers in a high-value niche, and Luken is challenging that position with its proprietary silicon wafer-based interposer technology.

Recent trends

In FY2024, consolidated revenue fell 45.5% YoY to approximately KRW 21 billion, with both operating profit and net income turning negative; the operating loss was approximately KRW 3.3–3.4 billion and the net loss was approximately KRW 3.28 billion, primarily driven by a sharp contraction in display inspection equipment orders following steep cuts in capital investment by the key customer, LG Display.

This outcome exposed the structural vulnerability of a business model heavily weighted toward project-based inspection equipment sales, which is directly sensitive to individual customer capex cycles.

Nevertheless, 2024 marked a meaningful turning point for semiconductor business development: the TIU unit acquisition from ISC was completed in April, Samsung Electronics vendor registration was secured in August, and TIU-related interface board and connector revenues contributed an estimated KRW 1.5 billion for the year.

A KRX corporate analysis report published in October 2025 projected 2025 revenue to recover to KRW 24.1 billion (+14.8% YoY) with the operating loss narrowing to approximately KRW 1.8 billion, driven by a partial display cycle recovery and initial semiconductor parts contributions.

In July 2025, the company announced the completion of silicon wafer-based interposer development for HBM testing and projected combined annual revenue exceeding KRW 30 billion from DSA boards, interposers, and M-POGO products if HBM4/HBM4E adoption proceeds.

As of June 7, 2026, the share price stood at KRW 2,735—more than 47% below the 52-week high of KRW 5,200—reflecting both execution uncertainty and the limited market visibility inherent in small KONEX-listed companies.

Daily trading volume at approximately KRW 7.4 million underscores the severe liquidity constraints of the KONEX tier.

Outlook

Management has publicly committed to a KOSDAQ technology special listing target of May–June 2027, directing all efforts toward securing sufficient semiconductor test consumable parts revenues to meet listing criteria.

The structural surge in HBM3 and HBM4 adoption driven by AI accelerator demand is expanding back-end semiconductor testing investment, creating a credible medium- to long-term addressable market for Luken's wafer interposers, vertical probe cards, and test sockets.

A particularly significant structural advantage is the partnership with Teradyne, a global inspection equipment leader, whereby Luken's custom DSA boards and test sockets are built into Teradyne platforms, effectively automating the customer qualification entry process and lowering market access barriers.

The expansion of M-POGO Pin exports to Chinese and Taiwanese probe card makers, combined with vendor registration at a Chinese memory manufacturer in 2025, reduces domestic revenue concentration and broadens the international growth base.

The breakeven point is expected no earlier than 2026, and the pace of semiconductor parts revenue ramp-up and the progress of customer qualification milestones will remain the key variables determining any meaningful rerating.

Should the KOSDAQ uplisting materialize, enhanced market visibility and improved liquidity could support a valuation premium, but achieving the required revenue and profitability trajectory must precede that outcome.

Management has also presented a long-term scenario of annual revenues reaching KRW 200 billion if HBM4/HBM4E-related vertical probe card and interposer supplies scale fully, though this target carries substantial execution-dependent uncertainty.

Bull factors

First-Mover in HBM Test Interposer Domestication

The HBM test interposer market is a high-value segment dominated by Japanese suppliers, and Luken's completion of silicon wafer-based interposer development positions it as a credible domestic alternative.

Vertical integration through the in-house MEMS Fab—enabling design, fabrication, and quality inspection under one roof—underpins a meaningful cost structure advantage over global peers.

Original interposer patents filed since 2017, combined with completed product validation of HBM test sockets and vertical probe cards, form a tangible technological entry barrier.

The company projects combined annual revenue exceeding KRW 30 billion from DSA boards, interposers, and M-POGO products if the ultra-fine M-POGO Pin is adopted in HBM4 and HBM4E devices.

Teradyne Partnership and Customer Base Expansion

The integration of Luken's custom DSA boards and test sockets as standard components in Teradyne inspection platforms creates a structural market entry mechanism that automates the end-customer qualification process, a meaningful competitive moat.

The customer base has been expanding sequentially—Samsung Electronics vendor registration was completed in August 2024, and a Chinese memory maker's vendor qualification was secured in 2025.

The ramp-up of M-POGO Pin exports to Chinese and Taiwanese probe card manufacturers further diversifies the revenue base internationally, progressively reducing dependence on domestic display customers.

KOSDAQ Uplisting as a Potential Rerating Catalyst

At a November 2025 IR presentation, management formally announced a KOSDAQ technology special listing target for May–June 2027, drawing market attention to the company's growth ambitions.

If the uplisting is achieved, the dramatically higher liquidity and broader institutional and foreign investor accessibility of KOSDAQ would be unlocked, materially increasing the probability of a valuation rerating as a recognized semiconductor inspection parts specialist.

With comparable peers Leeno Industrial and ISC as valuation reference points, management has explicitly acknowledged that expanding semiconductor parts revenue and achieving breakeven are the necessary preconditions to approaching peer-level multiples.

Bear factors

Sustained Operating Losses and Small Revenue Base

In FY2024, the consolidated operating loss was approximately KRW 3.3–3.4 billion and the net loss was approximately KRW 3.28 billion, with a further operating loss of approximately KRW 1.8 billion projected for 2025.

The breakeven point is expected no earlier than 2026 and is contingent on timely semiconductor parts revenue growth, meaning execution risk remains substantial.

With annual revenues currently in the low KRW 20 billion range, the scale gap relative to sector leaders—both operating at several hundred billion KRW—is unlikely to narrow in the near term and constrains customer bargaining power and R&D investment capacity.

Display Dependency and Key Customer Concentration

The display segment historically accounted for 80–90% of revenues, and the dramatic 2024 sales collapse was directly triggered by a single customer—LG Display—curtailing capital investment.

Despite the ongoing semiconductor pivot, the display business still represents a significant share of revenue, making near-term results highly sensitive to panel maker capex cycles.

In the emerging semiconductor segment, revenues are likely to remain concentrated among a small initial customer base—Samsung Electronics and Teradyne-linked accounts—meaning customer concentration risk persists until meaningful diversification is achieved.

KONEX Liquidity Constraints and Low Market Visibility

Luken's KONEX listing imposes severe liquidity constraints, with daily trading value typically in the low single-digit million KRW range—approximately KRW 7.4 million on June 7, 2026.

Limited market visibility and restricted access by institutional and foreign investors on KONEX weakens price discovery and confines the investor base available to catalyze a rerating.

Should the KOSDAQ uplisting be delayed—or if profitability milestones are not met in time to satisfy listing requirements—this liquidity discount could persist indefinitely.

Risk factors

Macro / Industry Cycle Risk

An unexpected slowdown in global AI investment or weakening HBM demand growth would directly impair the anticipated uplift in semiconductor inspection parts orders that underpins the bull case.

Escalating U.S.–China semiconductor trade restrictions could constrain or derail revenue diversification efforts targeting Chinese memory makers, undermining the international growth scenario broadly.

A broader global economic slowdown delaying display panel demand recovery would also prolong weakness in the legacy business segment, compounding the accumulated deficit burden.

Technology & Business Transition Risk

Delays in qualification processes at new semiconductor inspection customers could push out revenue recognition, directly jeopardizing both the profitability turnaround timeline and the KOSDAQ listing schedule.

Failure to secure mass-production adoption for new products such as the wafer interposer—or losing competitive ground to established MLC/MLO alternatives—could undermine the semiconductor growth narrative entirely.

As a small company, the risk of key R&D talent attrition and operational risks from underutilization of the MEMS Fab creating fixed-cost headwinds are also latent concerns.

Competitive & Market Entry Risk

Sector leaders Leeno Industrial and ISC hold multi-hundred-billion KRW revenue bases with deep customer relationships, while international competitors with comparable pogo-pin and probe card technologies are active participants in the HBM inspection parts space.

If Japanese interposer suppliers respond rapidly with price reductions or accelerated product improvements, Luken's cost structure advantage could erode.

Vertical integration moves by inspection equipment makers or in-sourcing strategies by major chip manufacturers represent broader structural threats to external component suppliers.

Overall view

Luken Technologies has accumulated meaningful technological and customer foundations for its semiconductor test components transition—including proprietary MEMS Fab-based vertical integration, wafer interposer patents, a Teradyne partnership, and Samsung Electronics and Chinese memory maker vendor registrations.

However, the financial burden remains significant, with a 45.5% revenue collapse in FY2024 driving an operating loss that is expected to continue through 2025.

The timing of breakeven, the expansion of semiconductor parts to over 50% of revenues, and the successful execution of the KOSDAQ technology special listing are the three pivotal milestones that will determine future enterprise value.

The strategic direction and technology assets support a credible medium- to long-term growth thesis, but a meaningful valuation rerating requires prior confirmation of earnings visibility.

Given the combination of extremely thin KONEX liquidity, small-cap risk, and sustained operating losses, a cautious stance—pending concrete evidence of the semiconductor revenue transition—is appropriate at this stage.
