Hrs

Founded in 1981 and listed on KOSDAQ in 2000, HRS is a 45-year-old silicone rubber specialist operating a single business segment—the manufacture of silicone rubber products.

Korea's silicone rubber market is dominated by a duopoly between market leader KCC (roughly 33% share) and HRS (roughly 30% share), together accounting for more than 60% of the market.

HRS specializes in the downstream process of purchasing imported GUM (siloxane polymer) intermediate material and compounding/processing it, whereas KCC operates a vertically integrated process spanning metal silicon, GUM synthesis, and final products.

Key products span electronics keypads and O/A rolls, automotive spark plug boots and EV fire-prevention materials, construction and nuclear fire-retardant sealants, medical goods, and high-voltage insulation materials.

Annual production capacity is around 12,000 tons, and the company's core competitive edge lies in flexible, small-batch, multi-product manufacturing tailored to individual customer needs rather than standardized mass production.

In the second half of 2024, reports emerged that Hyundai Motor Group had adopted HRS silicone rubber for EV fire prevention, highlighting expansion potential in automotive applications.

In the nuclear segment, HRS has a track record of supplying large volumes of silicone fire-retardant material to the Saeul Nuclear Power Plant Units 3 and 4, with market attention on potential future supply to projects such as Shin-Hanul Units 3 and 4.

The core of the company's growth strategy is upstream expansion at the Pyeongtaek Seotan industrial complex, aimed at reducing raw material purchasing volatility and shifting the product mix toward higher value-added items.

HRS's annual revenue declined from KRW 86.1bn in 2022 to KRW 78.2bn in 2023, recovered to KRW 80.2bn in 2024, then edged down again to KRW 78.9bn in 2025.

Operating margin improved steadily from 13.3% in 2022 to 16.0% in 2023 and 18.6% in 2024, before slipping slightly to 17.0% in 2025, while owner net income rose from KRW 10.0bn in 2022 to a peak of KRW 15.1bn in 2024 before declining to KRW 13.5bn in 2025.

On a quarterly basis, 4Q25 was a relatively weak period, with revenue of KRW 19.0bn and operating profit of KRW 2.4bn, pushing the operating margin down to about 12.5%.

The trend then recovered in 1Q26 with revenue of KRW 20.9bn and operating profit of KRW 3.1bn, and 2Q26 posted the highest quarterly revenue in the dataset at KRW 24.7bn, with operating profit expanding to KRW 4.4bn and operating margin rising to 17.7%.

Notably, 2Q26 owner net income of KRW 6.9bn substantially exceeded the same quarter's operating profit of KRW 4.4bn, suggesting non-operating items or one-off factors played a meaningful role in the bottom-line jump.

Summing the most recent four quarters (3Q25 through 2Q26), revenue totaled roughly KRW 85.4bn and operating profit roughly KRW 13.8bn, both exceeding the full-year 2025 figures and indicating a recovering revenue trend.

Still, as the 4Q25 margin dip illustrates, quarterly volatility persists, and whether the 2Q26 net income surge reflects a one-off item or a more structural improvement will require confirmation in subsequent quarterly results.

The global organic silicone industry is currently undergoing restructuring aimed at easing oversupply.

Norway-based Elkem, one of the world's top-five silicone producers, has classified its silicone business as discontinued and is pursuing a divestiture, which industry reports expected to close in the first half of 2026.

Dow announced the closure of its UK silicone plant by mid-2026, citing deteriorating cost competitiveness from rising European power costs.

Chinese silicone producers have also shown weak profitability: Hoshine Silicon's operating margin turned negative at -2.9% in 2Q25, while Shandong Dongyue's operating margin was a thin 0.5% in the same period, barely staying profitable.

Germany's Wacker Chemie likewise saw its operating margin fall sharply over two consecutive years, from 17.9% in 2022 to 5.2% in 2023 and 4.7% in 2024, reflecting broadly weakened profitability among global upstream players.

In contrast, prices of D4 (MeSiO4), a key intermediate raw material for GUM, trended down from an average of about $10,000 per ton in 4Q24 to $7,349 in 3Q25, before rebounding 23.4% month-over-month to $9,269 in October 2025.

Amid this upstream restructuring and earnings weakness among global peers, HRS—specialized in downstream compounding—is seen as maintaining relatively higher profitability, supported by its purchasing leverage and customized customer response capability.

The company's medium-to-long-term growth story hinges on whether the upstream expansion at the Pyeongtaek Seotan industrial complex proceeds.

Pyeongtaek city announced completion approval for Zone 1 (188,800 square meters) of the Seotan general industrial complex development on October 31, 2025, marking administrative progress on the long-delayed new plant investment.

Once completed, the plan is to relocate the existing 6,000-pyeong Pyeongtaek plant to the 2.5-times-larger 15,000-pyeong Seotan facility, with plant design to proceed during 2026 and an operational target of around 2028.

However, a lawsuit filed against the company disputing the validity of the business rights transfer related to this project—following a loss at first instance in July 2023 and a partial loss at second instance in August 2024—remains pending at the Supreme Court, and a final loss could raise recovery issues for roughly KRW 11.8bn already capitalized as construction-in-progress assets, leaving this as a key uncertainty.

Management expects that completing the upstream expansion would allow direct procurement of metal silicon and D4-series materials upstream of GUM, supporting cost competitiveness and a richer product mix.

In the near term, tightening EV fire safety regulations and the progress of nuclear plant construction projects are cited as variables affecting demand for silicone fire-retardant and functional materials.

According to Korea Hydro & Nuclear Power, as of the end of March 2025 the Shin-Hanul Units 3 and 4 project was at the site-leveling stage, suggesting it will take further time before actual finishing-material supply begins.
