SyntekaBio Largest Shareholder Jongseon Jeong Files Amendment to Substantial Shareholding Report… Corrects Special Relation Birthdate and Maintains 16.57% Stake

This amendment corrects minor clerical errors in the substantial shareholding report originally filed on July 2, 2026, primarily adjusting the birthdate of special relation Jeong Hae-sook to 760415.
All key financial figures including total shares held, ownership percentage, and the pledge agreement remain unchanged from the prior filing. The reporting person Jongseon Jeong and nine special relations collectively hold 4,020,601 shares representing 16.57% of total outstanding shares.
Largest shareholder Jongseon Jeong maintains a pledge of 2,800,000 shares approximately 11.54% with BSC Trading under a loan of 2.85 billion KRW at an annual interest rate of 12% and a collateral maintenance ratio of 160%.
The previously reported open-market purchases that increased the stake from 15.69% to 16.57%, funded by personal funds, are not altered by this amendment.
[AI Summary]This amendment is a routine administrative correction with no material impact on investment decisions. However, the existing high-interest pledge of the largest shareholder suggests potential personal financial risk, and future shareholding changes should be monitored.
