A10 Networks GC Robert Scott Weber Vests RSUs; 1,930 Shares Withheld
What Happened
Robert Scott Weber, General Counsel of A10 Networks (ATEN), had two performance-based RSU awards certified and converted to common stock. The filing shows conversions of 3,882 and 3,707 performance-based restricted stock units (reported as acquisitions at $0.00, code M) after performance conditions were met. Per the awards’ vesting schedule, one-half of each award vested on May 5, 2026. To cover tax withholding, 1,930 shares were withheld/sold on May 6, 2026 at $27.13 per share, yielding proceeds of $52,361 (reported as code F).
Key Details
- Transaction dates: May 5, 2026 (conversion/vesting) and May 6, 2026 (shares withheld/sold for taxes).
- Reported entries: two conversions/acquisitions (M) of 3,882 and 3,707 shares at $0.00; one disposition (F) of 1,930 shares at $27.13 for $52,361.
- Tax withholding: 1,930 shares were automatically withheld to satisfy tax liabilities (footnote F3 breaks this into 987 and 943 shares withheld from the two grants).
- Vesting schedule: Footnotes state the awards are performance-based (certified April 16 and April 22, 2026) but remain subject to time-based vesting — one-half vested May 5, 2026, with the remaining one-fourth vesting on each of the first and second anniversaries of the performance certification dates, subject to continued employment.
- Shares owned after the transaction: the Form 4 references Table I for post-transaction holdings; the precise total held after withholding is not included in the excerpt provided.
- Filing timeliness: Form was filed May 6, 2026 for transactions on May 5–6, which is within normal Form 4 timing (no late filing indicated).
Context
These were performance-based RSUs converting to shares (reported as acquisitions at no purchase price). The 1,930-share disposition was a routine tax-withholding/cashless settlement, not an open-market sale for investment reasons. Such withholding is common when RSUs vest and does not by itself indicate insider market sentiment.

- [F1]Performance-Based Restricted Stock Units were previously reported on February 10, 2025, each of which represents a contingent right to receive one share of common stock of ATEN, with vesting subject to the achievement of specified levels of the volume weighted average closing prices of a share of ATEN common stock during any one hundred (100) day trading period between February 6, 2025 and February 6, 2029. The first achievement date occurred on April 16, 2026, as certified by the compensation committee of ATEN, resulting in 3,882 units meeting the appropriate performance-based conditions. However, these shares remain subject to time-based vesting conditions and will therefore vest as to one-half (1/2) on May 5, 2026 and an additional one-fourth (1/4) on each of the first and second anniversaries of April 16, 2026, subject to continued employment. These shares are reflected on Table I.
