Ison James 4

What Happened

• James Ison, Chief Product Officer of One Stop Systems (OSS), was granted 34,313 restricted stock units (RSUs) on Feb 7, 2026 under the company's 2017 Equity Incentive Plan.
• To cover tax liabilities when some prior RSUs converted to shares, Ison forfeited 6,546 shares (at $9.24 each, $60,485) on Feb 7 and 3,120 shares (at $8.70 each, $27,144) on Feb 15 — a total forfeiture of 9,666 shares (~$87,629).
• Ison transferred (gifted) 8,213 shares on Feb 7 and 4,263 shares on Feb 15 (total 12,476 shares) to a revocable family trust of which he is trustee and a beneficiary.

Key Details

• Transaction dates and prices:
  • Feb 7, 2026: Award of 34,313 RSUs (A, $0.00 reported for grant); forfeited 6,546 shares for tax withholding at $9.24 (F); transferred 8,213 shares to trust (G).
  • Feb 15, 2026: Forfeited 3,120 shares for tax withholding at $8.70 (F); transferred 4,263 shares to trust (G).
• Ownership after transactions:
  • The trust now directly owns 12,476 shares (and these are indirectly owned by Ison as trustee per the filing).
  • The filing notes the reporting person continues to hold significant unvested RSUs (footnotes reference totals such as 148,076; 133,317; 125,934 unvested RSUs across grants), all subject to vesting conditions.
• Notable footnotes:
  • The 34,313-item entry is an RSU grant for ongoing executive service (F1).
  • Forfeitures were to cover tax withholdings when vested RSUs converted into shares (F3, F7).
  • Transfers to the trust are gifts/transfers to a revocable family trust where Ison is trustee and a beneficiary (F5, F9, F6).
• Filing timeliness:
  • The Form 4 was filed on Mar 2, 2026 for transactions occurring on Feb 7 and Feb 15, 2026 — this filing date is later than the typical 2-business-day reporting window and may be considered late.

Context

• The grant of RSUs (A) is an award, not an immediate open-market purchase or sale; value is realized only as RSUs vest and convert to shares.
• Forfeitures labeled F are routine tax-withholding actions when RSUs vest and convert; they are not open-market sales and generally do not signal a bearish view.
• Gifts/transfers to a family trust (G) are commonly estate-planning moves and do not necessarily reflect trading intent.
• Transaction codes: A = Award/Grant, F = Payment of exercise price or tax liability (withholding), G = Gift/Transfer.

Facts only — no speculation on motivations.
