Amosense

Founded in 2008 and listed on KOSDAQ in June 2021, Amosense is a materials and components specialist operating across three business areas: materials, modules, and devices and platforms, with core products including shielding sheets, automotive and RF modules, and IoT devices.

The company began with wireless-charging shielding sheets for Samsung Electronics smartphones and provided an early foundation for commercializing wireless charging technology, before expanding into automotive modules and IoT devices.

More recently, analysis has pointed to plans to expand UWB digital key module supply tied to Hyundai Motor Group's shift to software-defined vehicles and to internalize Si3N4 (silicon nitride) power substrates, positioning the company as a key supplier for future mobility and energy markets.

The most closely watched new business is the ceramic electrolyte substrate for solid oxide fuel cells (SOFC); after signing a memorandum with SK Ecoplant, Bloom Energy, and T&E Korea in December 2023 for localization and global supply chain development, initial shipments began in the first quarter of 2026.

The largest shareholder group includes Amotech and other related parties, and the technology cooperation relationship with parent company Amotech forms one pillar of the business foundation.

In terms of competitive structure, the shielding-sheet and wireless-charging-module business is a mature market contested by numerous domestic and overseas component makers, while SOFC ceramic substrates represent an early-stage segment where Amosense is entering as a localization substitute supplier in an area previously dominated by Japanese and Chinese vendors.

The core of the diversification strategy is to layer the new energy materials business on top of the existing smart device and automotive module revenue base to broaden the growth axis.

2025 consolidated revenue was KRW 122.1 billion, down from KRW 134.2 billion in 2024, while operating profit of KRW 5.32 billion (4.4% operating margin) came in below 2024's KRW 7.16 billion (5.3%), reflecting a modest margin decline.

Owners' net income fell sharply from KRW 1.74 billion in 2024 to KRW 0.50 billion in 2025.

In the prior year, 2023 revenue was KRW 87.5 billion with operating profit of only KRW 0.80 billion (0.9% margin) and a net loss of KRW 1.42 billion, while 2022 revenue of KRW 63.0 billion also came with a net loss of KRW 0.91 billion.

After consecutive losses in 2022-2023, the company turned profitable in 2024 before profit scale contracted again in 2025.

Quarterly figures show pronounced volatility: from revenue of KRW 29.07 billion, operating profit of KRW 1.29 billion, and net income of KRW 0.45 billion in 2Q25, results deteriorated sharply in 3Q25 to revenue of KRW 28.30 billion with operating profit collapsing to roughly KRW 0.04 billion and a net loss of KRW 1.68 billion, suggesting a significant one-off gap likely tied to non-recurring items.

The fourth quarter recovered to revenue of KRW 33.63 billion, operating profit of KRW 2.46 billion, and net income of KRW 1.08 billion, before easing again in 1Q26 to revenue of KRW 27.82 billion, operating profit of KRW 0.53 billion, and net income of KRW 0.18 billion, and then swinging to an operating loss of KRW 1.42 billion and net loss of KRW 1.60 billion in 2Q26, the second-largest loss of the last five quarters.

On a combined basis over the most recent four quarters (3Q25-2Q26), the company sits in net-loss territory, indicating that the annual earnings trajectory has not yet clearly stabilized.

On the balance sheet, 2025 operating cash flow turned positive at KRW 11.38 billion after three straight years of negative figures (-KRW 2.68 billion, -KRW 6.36 billion, -KRW 0.49 billion in 2022-2024), and total equity rose to KRW 43.25 billion from KRW 41.41 billion in 2024, though total liabilities also grew to KRW 93.88 billion, pushing the debt ratio up to 217.1%.

The wireless-charging shielding sheet and automotive module market that underpins Amosense's core business has entered a mature phase alongside the expansion of smartphones, wearables, and electric vehicles, with the global EMI shielding material market projected to reach USD 13.06 billion by 2034 in a moderate growth trajectory.

In contrast, the emerging SOFC ceramic substrate market is rising quickly on the back of surging AI data center power demand, with Bloom Energy reportedly planning to expand SOFC production capacity from around 2GW in 2026 to at least 4-5GW by 2027-2028.

Amid growing demand for onsite power generation capable of immediate supply near data centers, SOFC's shorter lead time relative to large nuclear reactors or SMRs has been cited as a driver of its adoption.

In this market, Bloom Energy has historically relied heavily on Chinese vendors for ceramic substrates but has recently pursued supply chain diversification and reduced reliance on Chinese suppliers, an environment described as favorable for domestic alternative supplier Amosense.

That said, this market remains at an early stage with limited revenue contribution so far, and it will take time to validate the company's competitive edge relative to rivals.

In the automotive module segment, new model launch effects and rising adoption rates of digital key options tied to Hyundai Motor Group's SDV transition have been cited as supporting stable growth.

Overall, Amosense occupies a position where the stable cash-generating capacity of its mature existing businesses (shielding sheets, automotive modules) coexists with the structural growth potential of an early-stage new business (SOFC).

The company's future direction appears heavily dependent on the pace of ramp-up in the SOFC ceramic substrate business.

Hanyang Securities reported in a February 2026 note that Amosense planned to expand production capacity from around 200,000 units per month to over 600,000 units per month during the third quarter, while SK Securities reported in a March 2026 note that the initial batch of SOFC ceramic substrates was believed to have shipped in the first week of March.

At the time of those reports, SK Securities estimated 2026 annual revenue at KRW 137.7 billion and operating profit at KRW 8.1 billion, while Hanyang Securities estimated revenue at KRW 142.8 billion and operating profit at KRW 11.0 billion, though neither brokerage provided a separate share price target.

However, actual combined revenue for the first and second quarters of 2026 came to only around KRW 55.0 billion, with an operating loss recorded in the second quarter, meaning substantial revenue expansion in the SOFC and automotive module segments would be needed in the second half to reach those earlier estimates.

In the automotive module segment, expanded UWB digital key module supply and internalization of Si3N4 power substrates tied to Hyundai Motor Group's SDV transition are cited as a medium-term supply base.

In past media interviews, the company stated it expected double-digit revenue growth and profit improvement based on growth in digital key modules and smart tag business.

Key points to watch going forward are whether the SOFC capacity expansion plan is actually executed and the real order volume Amosense secures amid Bloom Energy's supply chain diversification process.
