Largest shareholder's stake drops from 38.54% to 20.33% due to capital increase

Change in largest shareholder: from (주)덕양에너젠 and (주)울프 (combined 38.54%) to (주)덕양에너젠 and three related parties (combined 20.33%)
Reason: acquisition of shares by related parties and dilution from capital increase
Capital increase paid on 2026-05-11 increased total outstanding shares, diluting the largest shareholder's stake
(주)울프 remains a shareholder but is excluded from the new largest shareholder group; joint holding agreement remains valid
Purpose: simple investment, funded by equity
