Equity structure and governance analyst

Large indirect equity grant stems from a merger-related conversion, not open-market trading.

The transactions show Jerry Tang, as CEO, president and 10% owner, reporting an indirect acquisition of 26,297,214 AIB common shares via conversion of a derivative tied to the One Blockchain LLC business combination. This is part of closing mechanics, not discretionary buying.

Tiger Cloud LLC and VCV Digital Solutions LLC received 15,100,970 and 11,196,244 shares, with 200 shares forfeited back to the issuer for no consideration. All reported holdings are indirect, and Tang disclaims beneficial ownership beyond any pecuniary interest, so economic exposure depends on his stake in those entities.

Subsequent filings may further detail any changes in these indirect holdings or additional restructuring steps.
