Hatcheck, a fabless company specializing in semiconductor sensor ICs, made its debut on the KOSDAQ market. As the company is expanding its business areas from its magnetic sensor business, centered on mobile phones and home appliances, into industrial and environmental sensors, market assessments of its growth potential and technological competitiveness are expected to continue following the listing.

◆ Share Price Falls More Than 12% on First Day of Trading

Hatcheck closed at 20,500 won, down 2,950 won from the previous day, a decline of more than 12% from its initial public offering price of 23,000 won. Its industry classification is semiconductor manufacturing.

It is worth noting that Hatcheck's hoped-for IPO price range was set between 23,000 and 28,000 won, and the final offering price was fixed at the bottom of the band at 23,000 won. The number of shares offered was 1 million, with the total offering amounting to 23 billion won.

The competition rate for the institutional investor bookbuilding was 101.91 to 1. The subscription volume allocated to retail investors was between 250,000 and 300,000 shares, with subscriptions conducted through DB Financial Investment. In the public subscription, the final overall subscription competition rate was 25.73 to 1, the final proportional allocation competition rate was 51.46 to 1, and the number of subscription applications totaled 20,091.

◆ Roots in Magnachip's Sensor Business Team... Securing Geomagnetic Sensor Technology

Hatcheck is a fabless company specializing in semiconductor sensor ICs. Rather than owning its own semiconductor production facilities, the company concentrates its capabilities on product planning, design, and development, while using external foundries and post-process partners for manufacturing. Quality control, sales, and marketing after outsourced production are also key business areas.

The company's roots lie in system semiconductor sensor technology. Hatcheck was founded in February 2017 after being spun off from Magnachip Semiconductor's sensor business team. Building on the semiconductor magnetic sensor IC and environmental sensor IC technologies that Magnachip had accumulated since 2012, the company has expanded its own research and development capabilities.

Its main products include geomagnetic sensors, digital magnetic sensors, analog magnetic sensors, and temperature and humidity sensors. In particular, the company advanced existing third-generation geomagnetic sensor technology to independently develop fourth- and fifth-generation geomagnetic sensors, and has developed and mass-produced three-dimensional digital magnetic sensors based on its one-dimensional digital magnetic sensors.

Geomagnetic sensors are used for functions such as electronic compasses that measure direction by detecting the Earth's magnetic field. They can be used as sensor components implementing location and directional information not only in mobile devices including smartphones but also in various electronics.

◆ Securing Global Customers Including OPPO, Vivo, and Philips

As of March 2026, Hatcheck has secured major domestic and international electronics and home appliance manufacturers as its customer base. Its disclosed supply destinations include the handset business division of Company A and the appliance business division of Company B in Korea, as well as OPPO, Vivo, OnePlus, Lenovo, and Motorola. In the home appliance sector, the company supplies products directly to global manufacturers such as PHILIPS, De'Longhi, and Electrolux, or through module companies. The products supplied include geomagnetic sensor ICs, magnetic sensor ICs, and environmental sensor ICs that measure temperature and humidity.

◆ Challenge Is Expanding Application Areas... Supply and Demand Also a Variable

The task Hatcheck must solve after listing is how quickly it can expand its application areas while maintaining its existing customer base. In the semiconductor sensor market, competitiveness can be determined not only by sensor sensitivity but also by low-power implementation, product size, signal processing accuracy, magnetic field calibration technology, and customized design capabilities for individual customers. In particular, extending the mass production experience accumulated in mobile and home appliances to other industries could accelerate the diversification of its product portfolio.

The company has also laid out a strategy of upgrading the performance of its existing magnetic sensors and expanding its next-generation sensor IC and high value-added SoC product lines based on high-sensitivity, low-power, and miniaturization technologies.

Since newly listed stocks can show large price fluctuations in the early listing period depending on circulating volume and supply-demand conditions, not only the institutional and retail subscription competition rates confirmed during the offering process but also actual market supply-demand flows are expected to act as variables. Whether Hatcheck can leverage the technology it has accumulated in the magnetic sensor IC field and its experience supplying global customers to expand its growth areas after the KOSDAQ listing is expected to be a key factor determining its future corporate value.

For reference, NearsLab closed its first day at 28,650 won, down 12,550 won, a 30% decline.
