Insights

CEO’s stake rises in economic exposure through new convertible securities.

William W. Smith, Jr., CEO and Chairman of Smith Micro Software, reports beneficial ownership of 9,380,822 shares, or 32.3% of the common stock. This includes direct holdings and a large position held via the Smith Living Trust, where he and his spouse are co-trustees.

The trust purchased a secured convertible note convertible into 6,743,371 shares and a warrant for 8,818,254 shares. These instruments increase Mr. Smith’s potential equity exposure if converted or exercised, while 3,561,449 warrant shares are already counted as beneficially owned under Rule 13d-3(d)(1)(i).

Recent forfeitures of performance-based restricted stock and shares withheld for taxes modestly reduced outstanding grants but are routine compensation-related events. Future company filings describing any conversion of the note or exercises of the new warrant will clarify how much of this potential stake becomes actual common stock ownership.
