A10 Networks (ATEN) GC Robert Weber Sells Shares for Taxes

What Happened
Robert Scott Weber, General Counsel of A10 Networks (ATEN), had a total of 5,450 shares disposed (withheld) to cover tax obligations tied to vested restricted stock units. The withholding occurred in two transactions: 836 shares at $17.44 on 2026-01-31 (≈ $14,580) and 4,614 shares at $17.44 on 2026-02-01 (≈ $80,468), for a combined value of about $95,048. These were tax-withholding dispositions (code F), a routine result of RSU vesting rather than an open-market sale.

Key Details

  • Transaction dates and prices:
    • 2026-01-31: 836 shares withheld @ $17.44 = $14,580 (footnote F1)
    • 2026-02-01: 4,614 shares withheld @ $17.44 = $80,468 (footnote F2)
  • Total shares withheld: 5,450; total value ≈ $95,048.
  • Shares owned after transaction: Not provided in the supplied filing details.
  • Footnotes:
    • F1: Withheld automatically for taxes on performance-based RSUs granted 2/21/2023 that vested 1/31/2026.
    • F2: Withheld automatically for taxes on RSUs granted 2/21/2023, 1/30/2024 and 2/6/2025 that vested 2/1/2026.
  • Filing: Report filed 2026-02-03 (appears to be within the SEC’s typical two-business-day reporting window).
  • Transaction code meaning: F = shares withheld to satisfy tax withholding obligations on vested awards.

Context
This was an automatic tax-withholding event tied to RSU vesting (not an affirmative open-market sale). Such withholdings are routine and reflect tax settlement for vested equity awards rather than an insider signal about company prospects.
