Equity ownership analyst

Large shareholder reports a 300,000-share sale but retains a sizable position.

Yelena I. Pesic, part of a 10% owner group in Silvaco Group, reported selling 300,000 common shares at $1.99 each. Post-transaction, she directly holds 3,603,073 shares, indicating this is a partial reduction rather than an exit.

Footnotes explain the transaction stems from an arrangement described as a non-recourse stock loan, with proceeds capped at about 45% of the shares’ market value under that arrangement. The nature of the transaction is under dispute in an arbitral proceeding, which adds uncertainty around characterization but does not change the reported share counts.
