Knr Systems

KNR Systems was founded in 2000 as a test-equipment maker built on hydraulic and electric precision control technology, and listed on KOSDAQ in 2024 under the technology growth special listing track.

Its business is organized around three pillars: development and manufacturing of simulator-grade test equipment supplied to the automotive, rail, civil engineering and energy industries; development of hydraulic robot systems for special environments; and test-evaluation service work for government research institutes and large corporations.

Major customers include Hyundai Motor Group, POSCO, and various domestic and overseas public institutions, and the company has gained recognition for its hydraulic robot core component technology through a supply reference of hydraulic actuators to global robotics leader Boston Dynamics.

The test-evaluation service business generates stable, recurring revenue because it performs verification procedures that are routinely required during R&D phases in front-end industries such as automotive, shipbuilding, and steel, with large customers including Taiwan's RTRCC, POSCO, and domestic shipbuilders acting as a cash-cow.

The company is also expanding its robotic arm lineup, moving beyond its existing 200kg-class (UW) arms to a newly developed 400kg-class arm (TG) currently undergoing on-site testing with customers.

Because the business is centered on project-based order intake, results fluctuate due to timing differences between contract signing and revenue recognition, and the company has recently been expanding into nuclear decommissioning and aviation mobility test certification.

Annual revenue contracted for four consecutive years, from KRW 51.2 billion in 2022 to KRW 21.4 billion in 2023, KRW 18.5 billion in 2024, and KRW 15.9 billion in 2025.

Operating profit swung from a KRW 3.0 billion gain in 2022 to an operating loss of KRW 4.3 billion in 2023, widening to KRW 7.7 billion in 2024 and KRW 7.5 billion in 2025, with the operating margin deteriorating from 5.8% in 2022 to negative 47.4% in 2025.

Net income attributable to owners followed the same trajectory, moving from a KRW 1.5 billion profit in 2022 to losses of KRW 3.8 billion in 2023, KRW 7.9 billion in 2024, and KRW 8.5 billion in 2025.

On a quarterly basis, revenue was KRW 2.2 billion with an operating loss of KRW 2.8 billion in Q3 2025, then jumped to KRW 9.6 billion in Q4 2025 while the operating loss narrowed sharply to about KRW 0.4 billion, illustrating how project-based contracts concentrate revenue in specific periods.

Revenue then fell back to KRW 1.8 billion in Q1 2026 with a KRW 2.5 billion operating loss, before rising to KRW 4.5 billion in Q2 2026 with the loss easing to KRW 1.9 billion.

The debt ratio fell sharply from 306.9% in 2023 to 65.1% in 2024 before rising again to 105.1% in 2025, reflecting both IPO proceeds and the subsequent erosion of equity from accumulated losses.

Operating cash flow deteriorated sharply to negative KRW 11.6 billion in 2024 before the outflow narrowed to negative KRW 2.0 billion in 2025. Overall, even on a trailing four-quarter basis from Q3 2025 through Q2 2026, a clear turnaround in profitability has not yet been confirmed.

The global robotics industry is evolving from simple repetitive-task collaborative robots toward next-generation AI humanoid robots and heavy-duty industrial robots, a shift said to be driving a paradigm change in drivetrain components.

Hydraulic-based actuation is seen as advantageous over electric drives in force density and heavy-load handling, and KNR Systems has been described as the only domestic company to have internalized a full hydraulic robot core component lineup and commercialized it.

In the nuclear decommissioning market, after the permanent shutdown of Korea's early reactors Kori Unit 1 and Wolsong Unit 1, government-affiliated institutions under the Ministry of Trade, Industry and Energy have been pursuing technological self-sufficiency in decommissioning and laying the groundwork for entry into overseas decommissioning markets.

Heavy-water reactor (PHWR) decommissioning in particular is considered more difficult than light-water reactors due to greater structural complexity and higher radioactive contamination, and no commercial-scale pressurized heavy-water reactor has reportedly ever been successfully decommissioned worldwide.

This market is seen as having potential to extend to countries such as Canada, which operates the most heavy-water reactors globally, as well as Argentina, Romania, China and India.

In the test-equipment segment, certification demand is growing for new mobility applications such as eco-friendly vehicles and urban air mobility, and the company has sought to enter the battery verification testing market through a collaboration with Emerson Electric in response to this growth.

In terms of competitive positioning, large integrated automation and instrumentation firms have broadly entered electric robotics and general-purpose test equipment, while barriers to entry in hydraulic-based heavy-load, extreme-environment niches are considered relatively higher.

In January 2026, the company signed a roughly KRW 2.8 billion contract with the Korea Radioactive Waste Agency's environmental restoration institute (KRID) for a demonstration project to build a heavy-water reactor (PHWR) radioactive structure cutting platform, a project sized above the company's average quarterly revenue and designed as a roughly seven-month short-term project.

It subsequently announced in August 2026 that it had completed the world's first robot system for heavy-water reactor decommissioning, and said the system would enter final delivery procedures in September and be installed at KRID's heavy-water decommissioning technology institute in Gyeongju.

The company said it plans to leverage this demonstration experience to pursue decommissioning of light-water reactor radiation-controlled areas at Kori Unit 1 and Wolsong Unit 1 domestically, as well as entry into overseas decommissioning markets in Canada, Argentina, Romania, China and India.

In February 2026, it issued its first private convertible bond since listing, worth KRW 15.8 billion with no refixing terms, and said about KRW 9 billion of the proceeds would go toward factory expansion and facilities for actuator mass production, with the remainder allocated to R&D.

Using this capital, the company has begun developing a "super humanoid" robot with a maximum payload of up to 600kg, targeting an initial unveiling by the end of 2026, alongside a business model to supply robot arms, robot hands, and hybrid actuators both as complete systems and as standalone components.

In a March 2026 interview, the CEO projected that annual revenue would more than double from the prior year, citing about KRW 15 billion of project revenue deferred from the previous year now being recognized from the start of 2026, and said a turn to profitability was plausible given roughly KRW 7 billion in annual fixed costs and a revenue breakeven point of around KRW 30 billion.

These projections, however, reflect management's stated plans at the time, and whether actual revenue recognition and profitability improve accordingly will need to be confirmed through upcoming quarterly results.
