Sandie Gong and Devon Xu Disclose 12.3% Stake in Aditxt, Inc. Followed by Full Exit

On June 11, 2026, reporting persons Sandie Gong and Devon Xu filed a Schedule 13G disclosing a 12.3% ownership stake in Aditxt, Inc. (ADTX). The filing reports the beneficial ownership of 100,000 shares of Common Stock as of the event date of June 9, 2026. The shares were held in a brokerage account in the name of Sandie Gong, with her spouse, Devon Xu, holding trading authorization and shared dispositive power. Notably, the filing includes a clarifying statement under Item 6 indicating that while this initial 13G reports the 12.3% position held on June 9, the reporting persons subsequently disposed of all 100,000 shares on that same date. Consequently, as of the actual filing date of June 11, 2026, the reporting persons beneficially own zero shares. This filing appears to serve as a simultaneous disclosure of crossing the 5% threshold and the subsequent exit from the position. The calculation is based on 815,921 shares of Common Stock outstanding.
