Gfi

Founded in 2014, GFI is a specialist in battery fire-safety solutions built around its proprietary microcapsule extinguishing technology, AEGIS.

The unpowered technology releases extinguishing agent when the capsule ruptures at a set temperature, allowing it to respond to early-stage battery fires without any external power source or sensor.

Its flagship product, DI-KIT, is a direct-injection system that sprays extinguishing agent inside ESS battery packs, complemented by fire-safety sheets and thermal-runaway prevention pads.

According to research by ValueFinder, a large portion of revenue comes from DI-KIT (37.1% as of Q3 2025) and fire-safety sheets (25.4%), which together form the core of the revenue mix. Its principal customer is Samsung SDI, with which it has partnered since 2019, including jointly obtaining UL certification.

Within Samsung SDI's ESS safety-design ecosystem, GFI handles fire suppression while cooling systems and enclosure structures are supplied by other partners such as Hanjung NCS and Seojin System.

The company expanded its overseas supply base by establishing a China subsidiary in December 2024 and a US subsidiary in May 2025, and it listed on KOSDAQ on January 14, 2026 via a merger with a special-purpose acquisition company.

It recently signed a contract to supply and install DI-KIT at 20 of Samsung SDI's North American ESS sites, and over the medium term it aims to broaden its customer base into other battery-powered industries such as e-mobility, submarines, and robotics.

Consolidated revenue for FY2025 rose sharply to KRW44.96 billion from KRW24.24 billion in FY2024. Operating profit also increased to KRW6.75 billion from KRW5.49 billion, but the operating margin declined to 15.0% from 22.7%, indicating some margin dilution as revenue expanded.

Net profit attributable to owners swung from a profit of KRW5.35 billion in 2024 to a loss of KRW3.42 billion in 2025, a shift that becomes clear when examined quarter by quarter.

Operating profit in Q4 2025 was a solid KRW3.30 billion, yet net profit attributable to owners for the same quarter posted a large loss of KRW7.28 billion, which dragged the full-year result into negative territory.

The disconnect between healthy operating profit and a deteriorating bottom line points to a sizable one-off item in non-operating income or expense.

The trend improved thereafter: Q1 2026 posted revenue of KRW19.47 billion, operating profit of KRW2.90 billion and net profit attributable to owners of KRW3.04 billion, while Q2 2026 posted revenue of KRW15.54 billion, operating profit of KRW2.95 billion and net profit attributable to owners of KRW2.25 billion, extending net profitability for two consecutive quarters.

The company's own disclosure stated that first-half 2026 consolidated revenue rose 164.5% year over year to about KRW35 billion, with operating profit up 183.6% to roughly KRW5.9 billion, figures broadly consistent with the combined Q1-Q2 2026 results.

On the cash-flow side, operating cash flow remained positive at KRW3.25 billion in 2025 despite the net loss, suggesting the core business retained its cash-generating capacity. The debt ratio rose to 22.8% in 2025 from 16.5% in 2024, though the absolute level remains relatively low.

The ESS market is growing rapidly amid rising power-storage demand driven by AI data centers and renewable energy expansion, while requirements for battery fire safety are simultaneously intensifying.

According to Korea's fire authorities, roughly 50 ESS fire incidents occurred over the five years from 2020 through June 2025, and major accidents such as the fire at the National Information Resources Service center in Daejeon have further highlighted the importance of safety design.

As a result, competition in the battery industry is broadening from capacity and price to operational stability and risk-management capability.

Samsung SDI collaborates with partners including Hanjung NCS, GFI, and Seojin System to apply multi-layered safety designs covering cooling, fire suppression, and structural protection at the system level, with GFI occupying the role dedicated to fire suppression within this ecosystem.

Chinese companies are said to have dominated much of the North American ESS market to date, but GFI has stepped up efforts to penetrate this market following its listing.

ValueFinder projected the North American ESS market would grow at a compound annual rate of 39.3% through 2029, while SK Securities noted that DI-KIT is being supplied to major ESS products of a domestic battery-cell maker and could expand to next-generation ESS platforms.

The most concrete basis for the outlook is the North American supply contract with Samsung SDI, under which the installation of DI-KIT at 20 ESS sites through 2027 is expected to be a key variable for future results.

The company has stated plans to use this as a springboard to expand supply into additional regions such as Europe and Southeast Asia.

According to materials disclosed during the listing process, a battery fire-safety cell being co-developed with Samsung SDI is expected to be applied to SBB 2.0, a next-generation LFP-based ESS product, with related revenue expected to materialize from a later point tied to SBB 2.0's mass-production schedule.

The company is also reportedly developing new suppression systems, including non-fluorinated extinguishing agents, cited as a response to tightening global environmental regulations.

Over the medium to long term, the company has indicated a direction of diversifying its customer base into industries using secondary batteries, such as e-mobility, submarines, and robotics, in order to reduce its revenue dependence on Samsung SDI.

Maintenance and reinstallation revenue from existing ESS sites through its US subsidiary has also been cited as an emerging revenue source.

However, how much and when these new products and regional expansions will actually translate into revenue is something that needs to be confirmed step by step through future disclosures.
