Insights

Equity ownership & governance analyst

New 28.34% passive holder concentrates FOXX ownership but signals no activist intent.

Grazyna Plawinski Limited, led by director Xiaohan Li, now reports beneficial ownership of 2,508,276 securities, equal to 28.34% of FOXX’s common stock as of May 1, 2026. This arises from common shares plus 1,843,923 warrants with an exercise price of $11.50 per share.

The stake was acquired from Acri Capital Sponsor LLC via a Securities Transfer Agreement for total consideration of $1,881,831.53, using the reporting persons’ own funds.

"Number of Shares Beneficially Owned by Each Reporting Person With:"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
