William W. Smith, Jr. Increases Stake in Smith Micro Software to 37.3% via Warrant Exercisability

William W. Smith, Jr., Executive Chairman of Smith Micro Software, Inc. (SMSI), filed an amendment to his Schedule 13D on May 28, 2026, reporting an increase in beneficial ownership to 37.3%. This change primarily stems from shareholder approval on May 26, 2026, which triggered the exercisability of several common stock purchase warrants held by the Smith Living Trust. Specifically, a November 2025 warrant became exercisable for 2,236,136 shares, and September 2025 warrants became exercisable for an additional 87,048 shares due to adjustment provisions. In total, the reporting person now beneficially owns 11,695,827 shares, which includes 5,884,633 shares obtainable via warrants within 60 days. Mr. Smith holds sole voting power over 293,520 shares and shared voting power with his spouse over 11,402,307 shares held via the trust. The filing also noted minor share withholdings for tax obligations related to equity vesting in April and May 2026. This increase from a previous 32.3% ownership reflects significant further consolidation by the company's executive leadership.
