Gabel Daniel G. 4

What Happened
Daniel G. Gabel, Chief Financial Officer of ONE STOP SYSTEMS, forfeited 1,613 shares of common stock on May 11, 2026 to satisfy tax withholding when 5,000 vested restricted stock units (RSUs) converted into shares. The withheld shares were valued at $15.68 each, totaling approximately $25,292. The conversion produced 5,000 shares but 1,613 were retained for taxes, leaving a net of 3,387 shares issued to him from that grant.

Key Details

• Transaction date: 2026-05-11; filing date: 2026-05-28 (filed late relative to the typical 2-business-day Form 4 deadline).
• Withheld/forfeited shares: 1,613 at $15.68 per share; total value ≈ $25,292.
• The 1,613-share withholding occurred upon conversion of 5,000 vested RSUs; net shares issued from that conversion = 3,387.
• Footnote F1: Withholding was done using the market price at the time of forfeiture; these RSUs were part of a grant disclosed in the Form 4 filed Nov 11, 2024.
• Footnote F2: The filing notes the reporting person still holds 127,762 unvested RSUs subject to vesting conditions.
• Filing timeliness: Late filing may limit immediate interpretability; the transaction itself is dated 5/11/2026.

Context
This was a tax-withholding transaction (code F), not an open-market sale — a routine administrative action when RSUs vest. Such forfeitures to cover taxes do not necessarily indicate insider sentiment about the company; they simply settle tax obligations tied to equity compensation.
