Nvh Korea

NVH Korea started in 1984 as a specialist in automotive interior materials and has since grown into a group operating three business lines: auto parts, environment-energy (clean room/dry room), and bridge girders.

The core auto parts segment produces noise-vibration-harshness (NVH) control interior materials and engine control parts, supplying automotive interior and engine control parts to Hyundai Motor, Kia, and Volkswagen.

Through the 2018 acquisition of KNSOL, the company entered the clean room and dry room equipment business needed by the semiconductor, display, battery, and bio industries, supplying clean room and dry room solutions to semiconductor, battery, and bio companies.

The 2019 acquisition of Samhyun H (Samhyun PF) added a bridge girder business, an order-based public infrastructure operation supplying the Ministry of Land, Infrastructure and Transport and Korea Expressway Corporation, among others.

In 2024 the company transferred its electrification business unit to NVTS, exiting the EV battery module and injection-molded parts business and refocusing on its core operations.

Since diversification took hold, the revenue share of the environment-energy segment has steadily expanded, rising from 11% in 2018 to 32% in 2022.

In auto parts, the company competes with large domestic suppliers centered on Hyundai Motor and Kia's supply chain, while in clean rooms its affiliates have secured major domestic semiconductor and display companies as customers.

This portfolio spans automotive, semiconductor, and infrastructure cycles that move independently, spreading exposure across different industry cycles.

Consolidated revenue rose for four consecutive years, from KRW 1.230 trillion in 2022 to KRW 1.3714 trillion in 2023, KRW 1.5874 trillion in 2024, and KRW 1.6239 trillion in 2025.

Operating profit, however, ran between roughly KRW 53.1 billion and KRW 67.9 billion from 2022 to 2024 before turning to a loss of about KRW 21.9 billion in 2025, with the operating margin falling to -1.3%.

Owners' net income likewise swung from a profit of about KRW 11.7 billion in 2024 to a loss of about KRW 13.1 billion in 2025.

On a quarterly basis, results held up through Q2 2025 (revenue of about KRW 414.8 billion, operating profit of about KRW 24.1 billion), softened in Q3 2025 (operating profit of about KRW 11.3 billion), then deteriorated sharply in Q4 2025 with an operating loss of about KRW 72.5 billion and an owners' net loss of about KRW 39.5 billion, severely damaging the full-year result.

This Q4 loss appears linked to an impairment assessment flagged as a key audit matter, with the impairment testing of long-term loans forming part of the net investment in an associate identified as a principal audit focus.

Entering 2026, operating profit returned to positive with about KRW 10.5 billion in Q1 and about KRW 4.9 billion in Q2, but owners' net income was still weak at about negative KRW 0.5 billion in Q1 and about KRW 3.3 billion in Q2, not yet signaling a full recovery.

Over the most recent four quarters (Q3 2025 through Q2 2026), cumulative owners' net income totaled about negative KRW 35.7 billion, still in loss territory.

On the balance sheet side, the debt ratio climbed from 256.9% in 2022 to 371.1% in 2025, while operating cash flow also turned negative at about KRW 7.2 billion in 2025, indicating weaker cash generation alongside the earnings deterioration.

The auto parts industry is in a phase where NVH and lightweighting parts demand continues, driven by Hyundai Motor and Kia's global sales expansion and platform transitions.

The semiconductor and battery clean room/dry room industry is tied to renewed memory investment amid rising AI server and HBM demand, connected to an upturn in which global semiconductor sales grew 18% year on year in 2024.

In Korea, Samsung Electronics and SK Hynix have announced new investment plans following the announcement of a KRW 300 trillion semiconductor cluster and are resuming capital expenditure, improving the industry cycle that underpins clean room orders.

In batteries, expanding project awards from LG Energy Solution, Samsung SDI, and SK On are supporting dry room demand, while an expansion of the Songdo Bio Cluster is cited as an additional demand driver for bio clean rooms.

The bridge girder segment is tied to government infrastructure ordering and is influenced by the pace of public budget execution and SOC investment policy.

On a nine-month cumulative basis through Q3 2025, revenue rose 4.4% while operating profit fell 20.4%, illustrating an environment where cost and impairment factors weighed on profits even as revenue grew.

Compared with peers, the company's diversification away from a single auto parts business is a distinguishing feature, but this also brings the complexity of exposure to multiple separate cycles—automotive, semiconductor capex, and public SOC spending—simultaneously.

No official numerical guidance from the company has been confirmed, but renewed capex momentum in the semiconductor industry and expanding battery/bio clean room orders are cited as growth drivers for the environment-energy segment.

Growing dry room demand tied to EV battery market growth, with increasing project awards from LG Energy Solution, Samsung SDI, and SK On, is pointed to as a factor supporting future clean room revenue contribution.

An expansion of the Songdo Bio Cluster is expected to widen bio clean room demand as well, potentially broadening the clean room order base beyond semiconductors into the bio industry.

The auto parts segment showed signs of normalization with consecutive operating profits in Q1 and Q2 2026, though whether this trend continues needs confirmation in coming quarterly results.

Having transferred its electrification (EV battery pack) business to NVTS in 2024, future growth is likely to hinge on order momentum in the company's remaining core businesses—NVH parts, clean rooms, and bridge girders.

Whether the large impairment loss recorded in Q4 2025 proves to be a one-off event, or whether similar impairment factors recur, remains a key variable for gauging the reliability of future earnings.
