As of the latest fiscal year-end, the company reported standalone total assets of KRW 168.9 trillion, total equity of KRW 117.3 trillion, and a debt-to-equity ratio of 43.97%, with revenue of KRW 86.85 trillion, operating profit of KRW 44.01 trillion, and net income of KRW 42.69 trillion. The filing also lists 34,200 employees and an extensive roster of overseas affiliates spanning the U.S., China, Japan, Singapore, Germany, and other regions, primarily covering semiconductor sales, R&D, and the Solidigm NAND business. This is a routine regulatory filing with no new strategic announcements.

This is the annual large business group status disclosure as a member of the Doosan Group, covering company overview, financials, and ESG governance. FY2025 standalone results show revenue of KRW 303.9 billion with an operating loss of KRW 0.9 billion but net income of KRW 1.5 billion, while debt-to-equity stood at 61.02% with borrowings of KRW 200.5 billion.

A lawsuit filed by 7 plaintiffs seeking to cancel a shareholder meeting resolution has been finalized through a court-recommended settlement (화해권고결정). Under the settlement, plaintiffs withdrew their suit and the company agreed not to execute the corporate spin-off based on the July 16, 2025 EGM resolution approving the split plan. With no objections filed within the two-week period after delivery of the settlement decision, the case is now legally closed with the same effect as a final judgment. This amendment updates the confirmation date to May 29, 2026, reflecting issuance of the certificate of finality, and effectively ends the management-control dispute over the planned spin-off.

Samsung Asset Management filed an abbreviated large shareholding report disclosing that its holding fell to 1,494,087 shares (2.91%) from 2,592,254 shares (5.04%) as of May 12, 2026, a decrease of 1,098,167 shares (-2.13 percentage points). The change was driven by trading activity (simple acquisition/disposal) and includes 9,947 shares (0.02%) entrusted to Samsung Active Asset Management. The reported purpose remains simple investment, with no intent to influence management. Crossing below the 5% threshold means future changes of 1%p or more no longer require mandatory disclosure, reducing transparency on this institutional holder's future moves.

Hana Micron, the largest shareholder of Hana Materials, filed an amended large-holding report following a small on-market sale by a related party. Total holdings decreased by 5,000 shares, lowering the combined ownership stake from 44.87% to 44.84% (a 0.03 percentage point decline). The reporting entity and its seven specially related parties (executives and affiliates) collectively still hold 8,957,208 shares. The change was driven by an on-market sale by a specially related party, with the purpose maintained as 'influence over management.' Major contract-related holdings remain unchanged at 4,924,241 shares (24.66%).

The company filed its annual corporate governance report for fiscal year 2025, reporting an 80% compliance rate with the 15 core governance indicators. The board comprises 10 directors (2 inside, 6 outside, 2 non-executive), maintaining an independent director majority of 60% with an independent director serving as board chair. Consolidated financials show sharp improvement: revenue of KRW 97.1 trillion (vs. KRW 66.2 trillion prior year), operating profit of KRW 47.2 trillion (vs. KRW 23.5 trillion), and net income of KRW 42.9 trillion. SK Square and 9 affiliated parties hold 20.07% as the largest shareholder, while minority shareholders hold 63.34%. Non-compliant items include avoiding concentrated AGM dates, cumulative voting, and policies excluding executives who harmed corporate value or shareholder rights.

Samsung Asset Management filed an abbreviated large-holding report disclosing that its stake decreased from 350,152 shares (5.00%) to 201,905 shares (2.89%), a reduction of 148,247 shares (-2.11 percentage points) as of May 12, 2026. The change was triggered by trading activity, with the holding purpose declared as simple investment (no management participation intent). The reported position includes 530 shares (0.01%) entrusted to Samsung Active Asset Management. Detailed transaction records show a mix of on-market purchases and ETF setup/redemption-related movements at prices around KRW 258,000–271,125. Because the stake fell below the 5% threshold, this is the institutional shareholder's final mandatory disclosure unless its holding rises back above the reporting trigger.

A Samsung Electronics executive (Kim Kyoung-seok, Managing Director of Foundry FAB3 Team, appointed Nov 25, 2025) filed an insider ownership change report. His holdings increased by a net 1 share, from 236 to 237 common shares (0.00% of total shares outstanding). The activity included a small on-market purchase on Jan 30, 2026, plus a same-day buy of 1,249 shares and sale of 1,249 shares on May 29, 2026 at prices of KRW 320,500 and KRW 321,000 respectively. This is a routine non-registered executive disclosure with negligible economic significance relative to the 6.65 billion total shares outstanding.

This is the routine annual disclosure of the company's status as a member of the LX large business group, with no material new business events. Standalone FY2025 results show revenue of KRW 1,639.1B, operating profit of KRW 105.6B, and net income of KRW 82.5B, with a low debt-to-equity ratio of 24.42% and no interest-bearing debt. The board approved a capacity expansion investment for the heat-dissipation substrate business in July 2025, signaling continued diversification beyond Driver IC. New inside director Lee Hyuk-joo (Management Support Division head) was appointed in March 2026, and there were no changes in affiliate composition during the period.

Subsidiary Cheonbo BLS completed the issuance of its 1st unregistered, coupon-bearing, unsecured private placement convertible bonds, with the full KRW 78.2 billion paid in on May 29, 2026. The board originally resolved on the issuance on May 22, 2026, and the actual issued amount matched the planned amount in full. The CBs will not be listed. This is a sizable capital raise at the subsidiary level that strengthens funding but introduces potential future dilution at the subsidiary upon conversion.
