Insun Environmental New Technology

Insun ENT was established in 1997 for construction-waste collection, transport, and intermediate treatment, and listed on KOSDAQ in 2002 as an integrated environmental company.

Its business lines comprise construction-waste treatment, recycled aggregate production and sale, incineration, and landfill processing, while its subsidiary Insun Motors handles end-of-life vehicle dismantling and shredding recycling.

The company holds integrated processing technology and patents spanning demolition of scaffold structures through final waste disposal, a differentiating factor among domestic construction-waste operators.

Its landfills operate in Sacheon, South Gyeongsang (general waste) and Gwangyang, South Jeolla (designated waste), and permitting barriers for new landfill and incineration facilities in Korea give the business a relatively high entry barrier.

As of the first half of 2023, construction-waste intermediate treatment accounted for roughly 59.0% of revenue, auto-recycling sales for 35.8%, and landfill for about 7.4%, though the mix has shifted since with market conditions.

The parent is the IS Dongseo Group, which has been described as positioning Insun ENT (via Insun Motors) to secure raw-material feedstock within the group's battery-recycling value chain.

Competitively, the company shares the market with regional waste operators such as YNTech and Koentec, with Insun ENT's vertically integrated chain from collection to final disposal cited as a strength. The auto-recycling segment is also expanding beyond scrap dismantling into EV battery collection and distribution.

Consolidated revenue in 2025 came to KRW 187.15 billion, down 10.4% from KRW 208.85 billion in 2024, while operating profit fell 21.4% to KRW 18.23 billion, with the operating margin narrowing from 11.1% to 9.7%.

Net loss attributable to owners was KRW 10.93 billion, smaller than the KRW 18.86 billion loss in 2024, but a second consecutive year in the red.

Revenue and operating profit peaked in 2022 at KRW 237.62 billion and KRW 33.23 billion (a 14.0% margin), then declined for three straight years through 2025, while owners' net income moved from a KRW 21.90 billion profit in 2022 to a modest KRW 1.71 billion profit in 2023 before slipping into losses in both 2024 and 2025.

On a quarterly basis, net losses of KRW 2.23 billion, KRW 1.20 billion, and KRW 5.36 billion were recorded in Q2, Q3, and Q4 of 2025, respectively, but the company posted net profits of KRW 1.72 billion in Q1 2026 and KRW 1.24 billion in Q2 2026, marking two consecutive profitable quarters.

Operating profit itself, however, was KRW 2.79 billion in Q1 2026 and KRW 2.32 billion in Q2 2026 — lower than the KRW 5.38 billion and KRW 5.90 billion posted in Q3 and Q4 of 2025 — suggesting the return to net profit may have been influenced by non-operating factors.

On the balance sheet, total liabilities fell steadily from KRW 208.37 billion in 2022 to KRW 155.52 billion in 2025, and the debt ratio declined from 61.0% to 50.3%, indicating that financial soundness improved even as earnings remained weak.

Operating cash flow stayed positive throughout, at KRW 33.92 billion, KRW 29.50 billion, KRW 31.51 billion, and KRW 27.76 billion from 2022 to 2025, reflecting a capital-intensive business where non-cash items such as depreciation weigh heavily on reported net income independent of cash generation.

Korea's waste-treatment industry broadly splits into construction waste, which is cyclically sensitive, and landfill/incineration, which carries high regulatory entry barriers, and Insun ENT is cited as one of the few domestic operators vertically integrated across both.

The construction-waste intermediate-treatment segment is directly tied to the construction cycle, and a persistent decline in waste generation amid the recent construction downturn has been identified as the main driver of the recent earnings weakness.

By contrast, landfill and incineration capacity is structurally supply-constrained due to permitting difficulties and limited available space, with processing rates on an upward trend, a dynamic viewed as leaving room for margin improvement.

This reflects the broader industry feature that landfill and incineration are regulated businesses with high entry barriers, favoring incumbents. Competitors include regionally based operators such as YNTech and Koentec, each holding its own landfill and incineration infrastructure.

The auto-recycling segment's results are linked to raw-material prices such as steel scrap, and industry observers note the potential emergence of an EV battery collection and recycling market as a new growth driver as electric-vehicle adoption expands.

Overall, the sector is currently experiencing a downturn in the construction cycle alongside structural supply constraints in the regulated landfill/incineration business, with the two forces pulling earnings in opposite directions.

The company appears to be maintaining a profitability-focused strategy in the construction-waste segment, prioritizing nearby contracts and price discipline over volume expansion amid the ongoing construction downturn.

In the landfill/incineration segment, structural supply shortages stemming from permitting constraints continue alongside a rising processing-rate trend, making future utilization and pricing at these facilities a key variable for earnings.

The auto-recycling segment remains tied to raw-material prices such as steel scrap and end-of-life vehicle volumes, with expansion continuing into new areas such as EV battery collection and distribution.

In April 2026, the board approved cancellation of 1 million treasury common shares (2.15% of shares outstanding), with the cancellation disclosed for May 8, 2026. This was described as a shareholder-value measure carried out within distributable profit limits without reducing paid-in capital.

The fact that owners' net income turned positive in both Q1 and Q2 of 2026 makes it an important checkpoint to determine whether this trend continues in coming quarters or reflects one-off factors.

Revenue and operating profit remain on a multi-year downward trend, leaving the pace of any construction-market recovery and landfill/incineration pricing increases as the key determinants of a potential earnings rebound.
