Hct

HCT is a testing, certification and calibration specialist listed on KOSDAQ since 2016, providing certification services across ICT, automotive electronics, batteries, and aerospace/defense industries.

The company has served as a designated testing institution for three domestic automakers since 2017, and it has also secured official EMC laboratory accreditation from global automotive group Stellantis.

In May 2026, it completed the 'M-Solution Center,' Korea's largest automotive electronics EMC testing infrastructure built to meet demand for high-voltage component testing in electric and autonomous vehicles, bringing its total to nine EMC chambers—including six high-voltage chambers—plus five shielded rooms.

In defense, supported by strong growth in domestic defense exports, the company built a defense reliability center and secured top-tier domestic defense companies as clients, with a large order from Hanwha Aerospace cited as a growth driver.

Overseas, the company expands testing, certification and calibration operations through subsidiaries in the United States and Indonesia, with the Indonesian unit centered on calibration services.

More recently, subsidiary H&H Bio completed the absorption merger of non-clinical efficacy evaluation specialist HUMIC, diversifying the business into the bio sector.

The core ICT device testing business tends to move with flagship smartphone and tablet launch schedules, while the automotive electronics segment benefits from rising EMC and environmental reliability verification demand tied to electrification and software-defined vehicles.

Competitively, the market includes public-sector-linked domestic test institutions alongside global certification bodies, and the company seeks differentiation through its automaker, defense, and telecom client base combined with continued infrastructure investment.

Annual revenue rose for four consecutive years, from KRW 67.1 billion in 2022 to KRW 74.1 billion in 2023, KRW 94.4 billion in 2024, and KRW 107.5 billion in 2025.

However, the operating margin, which had improved to 10.8% in 2023 and 11.9% in 2024, dropped sharply to 7.7% in 2025, and owner net income also fell from KRW 7.01 billion in 2024 to KRW 6.29 billion in 2025.

On a quarterly basis, performance stayed solid through 2025Q2 (revenue KRW 29.19 billion, operating profit KRW 4.97 billion) and 2025Q3 (revenue KRW 28.07 billion, operating profit KRW 4.45 billion), consistent with the company's own disclosure at the time that revenue grew 16.0% and operating profit rose 61.1% year over year in the third quarter.

But in 2025Q4, revenue fell to KRW 24.6 billion and the company swung to an operating loss of KRW 2.59 billion and an owner net loss of KRW 1.95 billion.

In 2026Q1, revenue was KRW 24.72 billion with a thin operating profit of KRW 0.41 billion near breakeven, before slipping back into an operating loss of KRW 0.40 billion and an owner net loss of KRW 0.68 billion in 2026Q2 on revenue of KRW 25.61 billion.

Management attributed the weakness to declining test volumes in the ICT product certification business and the rescheduling of certain projects, noting that ICT-related test revenue that had been concentrated in the prior-year quarter shifted toward the second half this year.

Against this backdrop, cumulative owner net income over the trailing four quarters (2025Q3–2026Q2) came to only about KRW 0.87 billion, well below the annual profit levels of 2024–2025.

In sum, while revenue scale has steadily expanded, profit quality and stability have fluctuated with project recognition timing and client demand shifts.

The testing and certification industry's growth is closely tied to the pace of technology transitions in its downstream industries.

The ICT device segment has long been the company's core business, with 5G communication device certification revenue growing steadily from KRW 13.9 billion in 2017 to KRW 26.6 billion in 2020, reflecting demand expansion through successive wireless generation transitions.

More recently, electrification and the spread of software-defined vehicles have rapidly increased demand for EMC verification of high-voltage automotive electronics, an area directly linked to rising test volumes tied to automaker and parts supplier development schedules.

The defense and aerospace segment is seen as a growing market for reliability verification under high-power electromagnetic environments for guided munitions, unmanned combat systems, and next-generation fighter jets, alongside the expansion of Korean defense exports.

However, because revenue recognition in this industry is tied to client new-product launch schedules and project completion timing, quarterly earnings volatility tends to be relatively high.

On the competitive front, both public-sector-linked domestic test institutions and global certification bodies participate in the market, and the company leans on its designated-institution status with automakers and its Stellantis EMC accreditation as sources of technical credibility in specific client segments.

In terms of the industry cycle, the company is at a stage just after completing new infrastructure investment (the M-Solution Center), making how quickly that investment translates into utilization a key point to watch for future earnings.

In its 2026Q2 earnings release, the company stated that it expects a recovery in ICT test volumes and revenue recognition from ongoing projects in the second half of the year.

It also outlined plans to focus on earnings improvement through key client engagement, securing new demand, raising utilization at new test facilities, and expanding profitability at overseas subsidiaries.

In practice, the U.S. subsidiary expanded its operating scale after completing test chamber and facility expansion, which the company said resulted in a turn to profitability in 2026Q2.

Having just brought the M-Solution Center online with a total of nine automotive electronics EMC chambers including six high-voltage units, the company stated its intention to raise utilization and expand its mobility testing and certification business.

The CEO described the completion of the M-Solution Center as a strategic investment made proactively to address both the electrification and electronics trends in the automotive industry and growth in the aerospace and defense sectors.

With bio subsidiary H&H Bio having completed the absorption merger of HUMIC and moved into integrated operations, whether the combined non-clinical evaluation business becomes a new growth pillar is also worth monitoring.

These plans, however, represent management's stated direction, and the actual timing of revenue recognition and the pace of client demand recovery will need to be confirmed through upcoming quarterly results.
