Q1 2026 Quarterly Report: Capital Structure, Treasury Shares, and Articles of Incorporation Amendments

DUKSAN Tehera filed its Q1 2026 quarterly report (21st fiscal year) covering January-March 2026, with no changes to paid-in capital (KRW 10.24 billion, 20,476,584 common shares outstanding) and treasury shares unchanged at 49,775 shares (0.2% of issued shares). The company disclosed historical treasury share trust contracts, all of which were fully executed at near-100% completion and have since been terminated, with no current plan to dispose of or utilize existing treasury holdings. Material amendments to the Articles of Incorporation were approved at the 20th annual general meeting on March 31, 2026, including: (i) restricting shareholder meetings to in-person attendance only (per amended Commercial Act Article 364), (ii) allowing voting proxies to be submitted via electronic document (per amended Commercial Act Article 368(2)), and (iii) replacing the prior outside director requirement (1/4 of total directors) with a new independent director threshold of at least 1/3 of total directors. These changes are largely procedural compliance updates and do not signal a material change in operations or capital allocation strategy.
