Geumyang has amended a portion of the business report it disclosed in March of this year. The company explained that the measure was taken to correct typographical errors and input mistakes that occurred during the report drafting process.

According to the Financial Supervisory Service's electronic disclosure system on the 8th, Geumyang submitted an amendment report for its 71st term (2025 business year) business report. The target is the business report disclosed on March 23, with some financial statements and related notes having been modified.

This amendment focused on correcting numerical notation and unit input errors that occurred during the XBRL (eXtensible Business Reporting Language) drafting process. The main revisions are as follows:

• Notation of Rates and Discount Rates: The capitalization rate stated in the notes related to tangible assets was changed from the previous 5.69 to 0.0569, and the discount rate used in the intangible asset valuation process was also corrected from 19.77 to 0.1977. Additionally, the debt-to-equity ratio stated in the financial risk management section was re-noted to match the decimal format standard. • Borrowings and Corporate Tax Items: The total amount included in the short-term borrowings details was recalculated, and a sign notation error in the corporate tax expense item reflected in the separate statement of comprehensive income was corrected. • Notes Related to Retained Earnings: The unit notation for the legal reserve amount was corrected, and the remeasurement gain or loss of the defined benefit plan was also amended to match the actual figures.

Geumyang stated that this amendment is not due to changes in performance or financial structure, but rather to correct technical errors that occurred during the drafting process of the disclosure documents. Therefore, the company explained that the actual management performance or financial status itself has not changed.

Company executives also stated through an attached confirmation letter to the amendment report that a review of the overall disclosure content has been completed. The CEO and the executive in charge of reporting duties reaffirmed that the content included in the report aligns with the facts, and that there is no omission of important information or false entries.
