DI Dong Il Review: Structural Shift from Textiles to Aluminum and Environmental Solutions
Reviewing 3Q25 segment results, Dongil Aluminum merger, shareholder returns, and accounting-risk resolution
0. Bottom line first
DI Dong Il is shifting from a 70-year textile company toward battery-material aluminum foil and environmental plant solutions. Current numbers show textile revenue scale, aluminum profit contribution, and plant/environment losses at the same time.
Official fact: For cumulative 3Q25, textile materials revenue was KRW 246.18 billion, or 52.5% of total revenue, and aluminum revenue was KRW 180.735 billion, or 38.6%. Aluminum operating profit was KRW 6.203 billion, while textile materials recorded a KRW 991 million loss.
Interpretation: Textiles still dominate revenue, but the investment case is increasingly tied to aluminum, post-merger turnaround, and shareholder returns.
1. A turning point for a 70-year company
DI Dong Il, formerly Dongil Textile, was founded in 1955 and grew with Korea’s textile industry. In 2025, the company is repositioning around battery-material aluminum foil and environmental plant solutions.
The source analyzes 3Q25 filings, 2Q earnings materials, and 2026 K-battery outlook materials, focusing on segment revenue, the absorption merger of Dongil Aluminum, shareholder returns, and resolution of prior accounting issues.
2. Segment revenue and profit
| Segment | Cumulative 3Q25 revenue | Revenue share | Operating profit/loss |
|---|---|---|---|
| Textile materials | KRW 246,180mn | 52.5% | (KRW 991mn) |
| Aluminum | KRW 180,735mn | 38.6% | KRW 6,203mn |
| Plant/environment | KRW 15,578mn | 3.3% | (KRW 3,781mn) |
| Furniture/retail | KRW 19,599mn | Presented in source | Diversified business item |
Interpretation: Textile materials are large but weak in profit contribution. Aluminum is smaller by revenue but central to profit.
Textile materials
The company has production bases in Vietnam, Indonesia, and Egypt, but cumulative 3Q25 loss is shown.
Aluminum
Battery aluminum foil growth and the Dongil Aluminum merger are the key thesis.
Plant/environment
An environmental-solutions growth axis, but loss reduction must be verified.
3. Shareholder returns
The source interprets treasury-share cancellation as a strong shareholder-return measure because it reduces share count and immediately raises EPS and BPS. It also mentions cash dividends of KRW 4.98 billion and stock dividends of KRW 481 million in the 3Q report.
Official fact: Major shareholders and related parties held 25.53%, other shareholders held 58.07%, the National Pension Service held 4.09%, and foreign investors held 6.64%.
Interpretation: With a large outside shareholder base, the company cannot ignore minority-shareholder and value-up demands. Recent return policies signal an effort to address undervaluation.
4. Current accounting-risk status
The “recent accounting issue” in the source refers to regulator review and follow-up measures on 2015-2019 financial statements. As a result, DI Dong Il must be audited by a regulator-designated external auditor for fiscal years 2025-2027, the 83rd through 85th fiscal years.
Official fact: The external auditor changed from Woori Accounting Corp. to Deloitte Anjin, and the designated auditor expressed an unqualified opinion on the 3Q25 financial statement review.
Interpretation: The past issue is negative, but designated audit and an unqualified opinion can help rebuild accounting trust. Investors still need to monitor the 2025-2027 audit period for additional issues.
5. Financial condition and watch list
| Metric | End-3Q25 | End-2024 | Drivers |
|---|---|---|---|
| Total assets | KRW 994.0bn | KRW 1.0137tn | Dividends, share cancellation, asset revaluation |
| Total liabilities | KRW 467.4bn | KRW 449.4bn | Merger and working-capital changes to monitor |
- Aluminum profitability after Dongil Aluminum absorption merger
- Whether textile losses narrow
- Loss reduction and order quality in plant/environment
- Whether share cancellation and dividends become recurring policy
- Whether accounting risk declines further during Deloitte Anjin’s designated audit period
