Haechitech: 40% First-Day IPO Discount

Korea's sole geomagnetic sensor IC fabless company Haechitech plunged 39% below its IPO price on its first trading day, immediately confronting the twin challenges of restoring profitability and diversifying beyond mobile applications.

1
Korea's sole geomagnetic sensor IC fabless: Inheriting 40+ years of sensor heritage via LG Semiconductor → Hynix → MagnaChip, the company became the first domestic supplier of mass-produced geomagnetic sensor ICs to a global smartphone OEM in 2022
2
Full in-house value chain from device/circuit/algorithm design to QC: Outsources only wafer fab and back-end processes, retaining all core competencies internally for a higher structural barrier than a typical fabless model
3
FY2025 consolidated operating loss of KRW 2.40 bn and net loss of KRW 8.03 bn: Driven by declining China revenue amid US-China tech tensions and a KRW 3.4 bn non-cash RCPS derivative valuation loss; Q2 2026 saw a return to profitability
4
Day-one tradeable float of 38.42% and weak lock-up commitments: Mandatory holding commitment rate fell short of the 40% threshold; tradeable float expands to 48.33% one month post-listing and 50.30% at six months
5
Non-mobile diversification strategy targeting robots, data centers, mobility, and healthcare: KB Securities projects non-mobile revenue mix rising from ~25% in 2026 to 44.2% by 2028; company targets KRW 76.4 bn revenue by 2030

Business structure

Haechitech was established in 2017 when MagnaChip Semiconductor's sensor division was carved out; most core staff — including CEO Choi Sung-min — are MagnaChip alumni, and the company's technological lineage traces back 40+ years through LG Semiconductor (est. 1979), Hynix, and MagnaChip.

Headquartered in Cheongju, Chungcheongbuk-do with an R&D lab in Gangnam, Seoul, it operates as a pure fabless company, outsourcing wafer fabrication and back-end processing to external foundries.

Its product portfolio comprises geomagnetic sensor ICs for smartphone electronic compasses (63.7% of 2025 revenue), digital magnetic sensor ICs for motor and hinge angle detection (31.6%), analog magnetic sensor ICs (~1%), and temperature/humidity sensor ICs (~3%).

The company ships approximately 200 million sensor ICs annually, with cumulative shipments exceeding 700 million units.

The key differentiator is the full internalization of device and circuit design, signal-processing algorithms, mass-production test programs, and quality management — capabilities that go well beyond the circuit-design focus typical of most fabless companies.

This end-to-end competency underpins a 'Design-in' strategy where the company joins customer product planning from the earliest stage, structurally raising switching costs.

Key global competitors include AKM (Japan, long-dominant in geomagnetic sensors), TDK-Micronas (Japan), Allegro MicroSystems (US), and Infineon Technologies (Germany); Haechitech has gained share among Chinese OEMs such as OPPO and vivo by offering AKM-comparable performance at a lower price point.

The company is now developing higher-value products — TMR-based current sensors, high-precision encoders, and automotive position/temperature sensors — to penetrate robotics, data center, industrial automation, and automotive markets.

With 24 patents, two ISO certifications, and A/A technology ratings from KOTEC and NICE, it met the requirements for the KOSDAQ technology-exception listing route.

Recent trends

Haechitech's consolidated revenue grew rapidly from approximately KRW 3.9 bn in 2022 to KRW 11.5 bn in 2023 and KRW 16.2 bn in 2024, before dipping to KRW 14.078 bn in 2025.

Operating loss widened from approximately KRW 0.3 bn in 2024 to KRW 2.40 bn in 2025, while the net loss surged from KRW 0.05 bn to KRW 8.03 bn over the same period.

The primary driver of the net loss surge was a combination of declining revenue from Chinese customers amid US-China tech-supply-chain restructuring and a non-cash derivative valuation loss of approximately KRW 3.4 bn related to redeemable convertible preferred shares (RCPS).

Recovery signs emerged in 2026: H1 revenue reached KRW 9.2 bn and the company reported a return to quarterly profitability in Q2.

Backed by A/A technology ratings from KOTEC and NICE, Haechitech listed on the KOSDAQ via the tech-exception route on August 25, 2026, with the IPO priced at KRW 23,000 — the bottom of the KRW 23,000–28,000 guidance range.

Institutional demand-forecast competition was 101.91:1 from 321 institutions, but 27.5% of institutional orders were submitted below the final offer price and the mandatory holding commitment rate fell short of the 40% threshold, signaling tepid qualitative demand; retail subscription was 25.73:1 with roughly KRW 73.9 bn in subscription deposits.

The stock opened at KRW 20,500 on listing day, fell to an intraday low of KRW 17,090, and ultimately closed at KRW 13,930 — a 39.43% decline from the IPO price — on trading volume of approximately KRW 148.5 bn.

The day-one tradeable float of 38.42% of total shares and potential selling by non-locked-up shareholders including Pixelplus (7.14%) amplified supply-side pressure throughout the session.

Outlook

The company targets full-year 2026 revenue of KRW 21.0–21.1 bn, having already achieved KRW 9.2 bn in H1, making H2 execution the critical variable.

Its medium-term roadmap calls for revenue of KRW 31.8 bn with an operating profit turnaround in 2027, scaling to KRW 46.1 bn revenue and KRW 11.3 bn net profit in 2028, and KRW 76.4 bn revenue by 2030.

Non-mobile segment expansion is the central driver of this roadmap; KB Securities analyst Seong Hyeon-dong projected the non-mobile revenue mix rising from ~25% in 2026 to 44.2% by 2028.

Near-term catalysts include the commencement of temperature sensor shipments for enterprise SSDs at a domestic memory manufacturer starting in H2 2026 and initial volume production for Chinese new-form-factor smartphones.

The structural tailwind of physical AI and robotics expansion could drive growing demand for precision position, angle, and current-sensing magnetic ICs, though the typical one-to-three-year customer certification and Design-in cycle suggests that non-mobile revenue contribution will materialize gradually.

Notably, the company itself disclosed in the securities registration statement that 'discrepancies between estimated and actual performance of technology-exception-listed companies over the past three years have been considerable,' making quarterly earnings execution and the trajectory of the non-mobile revenue mix the key monitoring benchmarks.

With the stock now substantially below the IPO price, the market is clearly demanding visible and verifiable quarterly improvement rather than an optimistic outlook.

Bull factors

Domestic monopoly status and deep technical moat

Haechitech is Korea's only mass-production supplier of geomagnetic sensor ICs, combining a rare 40+ year analog semiconductor heritage with full in-house internalization of device, circuit, algorithm design, and quality management capabilities.

The company has received official A/A technology ratings from KOTEC and NICE, while 24 patents and cumulative shipments exceeding 700 million units underpin its technical credibility and supply reliability.

Since its breakthrough supply to a global smartphone OEM in 2022, customer diversification has been progressing, and the Design-in model structurally raises switching costs once engagement is established.

Its status as the first Korean geomagnetic sensor IC company to break the reliance on imported products provides a favourable positioning for building trust with large domestic and international customers over the medium to long term.

Physical AI and robotics demand driving non-mobile expansion

As physical AI ecosystems — including robotics, autonomous vehicles, and factory automation — expand, structural demand for precision position, angle, and current-sensing magnetic ICs could increase commensurately.

Haechitech has already secured non-mobile customers including a Chinese humanoid robot motor manufacturer and European premium home appliance and precision industrial equipment makers, and is developing TMR-based current sensors and high-precision encoders.

KB Securities analyst Seong Hyeon-dong projected the non-mobile revenue mix expanding from ~25% in 2026 to 44.2% by 2028; with mobile revenue remaining stable while non-mobile layers on top, a 'cumulative revenue' model is the central logic for medium-to-long-term growth.

Near-term non-mobile milestones — including temperature sensor shipments for enterprise SSDs at a domestic memory maker (H2 2026) and initial volume production for Chinese new-form-factor smartphones — are early visible datapoints for this expansion.

Q2 2026 profit turnaround and elimination of non-cash losses

The company reported a return to quarterly profitability in Q2 2026, and H1 revenue of KRW 9.2 bn already represents 65% of full-year 2025 revenue of KRW 14.1 bn, supporting expectations for H2 acceleration.

The non-cash RCPS derivative valuation loss (~KRW 3.4 bn) that materially distorted 2025 earnings has been structurally eliminated as preferred shares converted to common shares upon IPO listing.

Yujin Investment Securities analyst Park Jong-seon assessed Haechitech as having 'established a virtuous competitive advantage based on technology, mass production, and customer certification,' noting the company's targets of 37.9% CAGR in revenue and 30%+ operating margins from 2026 to 2030 driven by high-value product mix improvement.

The structural removal of a key profitability headwind provides a somewhat clearer path to earnings recovery, pending commercial execution.

Bear factors

Two consecutive loss years and an unproven medium-term roadmap

After two consecutive years of operating losses (2024–2025), the roadmap calling for an operating profit turnaround in 2027 and KRW 11.3 bn net profit in 2028 requires a dramatic multi-year earnings recovery.

The company itself disclosed in the securities registration statement that 'discrepancies between estimated and actual performance of technology-exception-listed companies over the past three years have been considerable,' and the fact that 2025 revenue declined year-over-year from 2024 adds to the uncertainty about plan execution.

The market's demand for visible, quarterly-verified progress rather than optimistic targets is reflected in the 39%+ discount to the IPO price already established on day one.

Heavy overhang and persistent supply-side pressure

Day-one tradeable float stands at 38.42% of total shares, rising to 48.33% one month post-listing and 50.30% at the six-month mark.

The institutional mandatory holding commitment rate fell short of the 40% threshold at the demand-forecast stage, and potential selling by non-locked-up shareholders — including Pixelplus (7.14%) and MagnaChip Semiconductor — remains an overhang.

The approximately KRW 148.5 bn in first-day trading volume — approaching the total market cap — indicates that substantial realized selling already occurred, and the scheduled expansion of tradeable float warrants continued monitoring as a supply-side volatility factor.

Mobile concentration and China customer dependency

Geomagnetic sensors still accounted for 63.7% of 2025 revenue, reflecting a high concentration in mobile and smartphone applications.

US-China tech tensions and the resulting supply-chain restructuring were among the primary contributors to the 2025 earnings deterioration, and a recurrence cannot be excluded given significant exposure to Chinese customers.

If non-mobile diversification proceeds more slowly than planned in an environment of structurally limited smartphone shipment growth, the revenue expansion path could narrow considerably; additionally, large analog sensor peers such as AKM, STMicroelectronics, and Infineon are rapidly broadening their portfolios through M&A and new product development, raising the competitive intensity Haechitech must navigate.

Risk factors

Macro & Geopolitical

Escalation of the US-China technology rivalry could trigger renewed revenue declines from Chinese smartphone OEMs (OPPO, vivo, etc.), while tightening US export controls on semiconductors could add broader uncertainty to foundry supply chains.

A global economic slowdown dampening consumer electronics demand would directly impact smartphone geomagnetic sensor volumes. Fluctuations in the KRW/USD exchange rate and shifts in major foundry (e.g., TSMC) capacity allocation could also affect cost structure and supply stability.

Business & Earnings Execution

The 2027–2030 medium-term earnings roadmap is predicated on successful mass-production entry in non-mobile new businesses and high-value product mix improvement, but customer certification and Design-in cycles typically require one to three years in semiconductors, creating material execution lag risk.

The '30%+ operating margin' target cited by Yujin Investment Securities represents a dual challenge — achieving massive revenue growth while simultaneously recovering profitability from a loss position.

Global peers such as AKM, STMicroelectronics, and Infineon are rapidly expanding their analog sensor portfolios through M&A and new product development, intensifying competition in the new markets Haechitech is targeting.

Financial & Liquidity

With a net loss of KRW 8.0 bn and an operating loss of KRW 2.4 bn in 2025, additional cash consumption is possible before reaching breakeven, and the pace of deployment of the KRW 23 bn in IPO proceeds for R&D investment warrants close monitoring.

As a small-scale fabless company, changes in major foundry capacity allocation or weakened bargaining power on pricing could adversely affect near-term profitability.

Additionally, the substantial stock price decline below the IPO price could raise the cost of accessing capital markets should additional financing become necessary in the future.

Overall view

Haechitech holds a distinctive position as Korea's sole geomagnetic sensor IC fabless company, with qualitative strengths including a 40+ year technology heritage and full internalization of the sensor development value chain.

However, the 39.43% first-day plunge from the IPO price starkly reflected the market's immediate discounting of two consecutive years of losses, a heavy overhang, and uncertainty surrounding the medium-term earnings roadmap.

The structural tailwind of expanding physical AI and robotics adoption leaves open the possibility of growing magnetic sensor demand, while mobile concentration and Chinese customer dependency continue to limit near-term earnings visibility.

H2 2026 temperature sensor shipment commencement, quarterly operating profitability achievement, and the trajectory of non-mobile revenue mix will be the key metrics for assessing the viability of the medium-term growth narrative.

Whether the 2030 targets of KRW 76.4 bn revenue and 30%+ operating margins are achievable depends on the pace of non-mobile diversification and new customer certification success — both of which investors will be able to evaluate incrementally through quarterly results.
