Zhiwei Liu and his wholly-owned vehicle Chunda International Capital Management Co., Ltd filed Amendment No. 1 to Schedule 13D with the SEC on October 27, 2026, reporting a decrease in beneficial ownership of Atlas Trinity Tech Co. ordinary shares following open-market sales on September 10, 2026.

Key Highlights

  • Open-market sale: Mr. Liu sold an aggregate of 111,050 ordinary shares on September 10, 2026, for aggregate consideration of approximately US$335,000.
  • Remaining beneficial ownership: The reporting persons collectively hold 377,326 ordinary shares, representing approximately 6.42% of outstanding shares.
  • Split holdings: The 377,326 shares consist of 132,087 shares held directly by Mr. Liu through Cede & Co. and 245,239 shares held by Chunda International Capital Management Co., Ltd.
  • Share base used: The ownership percentage is calculated on 5,874,743 ordinary shares outstanding as of October 23, 2026.
  • Issuer share issuance factor: The issuer issued 3,149,832 additional ordinary shares on June 29, 2026, in transactions to which neither reporting person was a party, also contributing to the change in percentage ownership.
  • Chunda dropped below 5%: As a result of the June 29, 2026 issuance, Chunda ceased to be the beneficial owner of more than five percent of the issuer's outstanding ordinary shares on June 22, 2026, according to the filing.

Zhiwei Liu Discloses Reduced Position in Atlas Trinity Tech Following Share Sales and Issuer Dilution

According to the filing, Zhiwei Liu, a Hong Kong-based individual, and Chunda International Capital Management Co., Ltd, a British Virgin Islands company wholly owned and controlled by Mr. Liu, submitted this amendment to update their beneficial ownership position in Atlas Trinity Tech Co. (NASDAQ:ATTT), whose ordinary shares carry a par value of US$0.0001 per share. The amendment supplements the original Schedule 13D filed on March 10, 2026.

The filing attributes the decline in the reporting persons' percentage ownership to two separate events. First, on September 10, 2026, Mr. Liu sold 111,050 ordinary shares in open-market transactions for aggregate consideration of approximately US$335,000. Second, the issuer itself issued 3,149,832 additional ordinary shares on June 29, 2026, in connection with separate transactions to which neither reporting person was a party, diluting the reporting persons' proportional ownership.

Following these events, the aggregate beneficial ownership of the reporting persons stands at 377,326 ordinary shares, representing approximately 6.42% of the issuer's outstanding shares based on 5,874,743 shares outstanding as of October 23, 2026, according to the filing. Mr. Liu retains sole voting and dispositive power over all 377,326 shares, while Chunda holds sole voting and dispositive power over the 245,239 shares it holds directly. The filing notes that Mr. Liu is deemed to beneficially own Chunda's shares by virtue of his control of that entity. Mr. Liu continues to beneficially own more than five percent of the issuer's outstanding ordinary shares, the filing states, while Chunda alone no longer meets that threshold.
