The company’s Form 6-K reports cover board and officer changes, independent-director appointments, committee assignments, shareholder meeting materials and amendments tied to its Class A ordinary share structure.
The filing record also includes registered direct offering disclosures, securities purchase agreements, ordinary shares, warrants, pre-funded warrants and registration-statement references.

A Schedule 13G/A filing by LIAO YEN-KAI reports a reduced ownership position in Ostin Technology Group, representing an exit from significant shareholder status. The filing indicates that Liao now holds 3,888,517 Class A Ordinary Shares, equivalent to 3.62% of the total outstanding Class A shares and 3.05% of total voting power.
Key details of the holding:
- Sole voting and dispositive power over all 3,888,517 shares
- No shared voting or dispositive power
- Based on issuer's total of 107,430,032 Class A shares and 200,000 Class B shares outstanding as of May 12, 2025
- Class A shares carry 1 vote per share, while Class B shares carry 100 votes per share
This amendment serves as an exit filing as the holder's ownership has dropped below the 5% reporting threshold. The shares were not acquired to influence control of the issuer.
Schedule 13G/A (Amendment No. 1) filing for Ostin Technology Group Co., Ltd. (OST) reports that individual shareholder Lo Sheng-Lun now holds 3,814,034 Class A ordinary shares, representing 3.55 % of the Class A float and 2.99 % of total voting power as of 19 June 2025. Because the position has fallen below the 5 % threshold, the submission is characterised as an “exit filing.”
The filing confirms: (i) sole voting and dispositive power over the entire stake, (ii) no shared voting or dispositive power, and (iii) no affiliation with a filing “group.” The stake size is calculated against 107,430,032 Class A and 200,000 Class B shares outstanding, figures taken from OST’s Form 6-K (12 May 2025) and Form 20-F (17 Jan 2025). Each Class A share carries one vote, whereas Class B shares carry 100 votes, explaining the lower percentage of overall voting power vs. economic ownership.
Implications for investors: dropping below the 5 % level removes mandatory Schedule 13D/G reporting going forward unless the stake rises again. Reduced insider ownership can be interpreted as potentially lower alignment with minority shareholders, but the filing gives no information on sale timing, price, or motivation. No other material corporate events, earnings data, or transaction details are provided.
