Caron Michelle Elizabeth 4/A

What Happened Caron Michelle Elizabeth, Chief Financial Officer of A10 Networks (ATEN), had 760 shares withheld on May 15, 2026 to satisfy tax obligations related to a performance-based restricted stock unit (RSU) grant that vested May 14, 2026. The withheld shares were reported at $28.03 per share for a total of $21,303. This was a tax-withholding disposition (transaction code F), not an open-market sale initiated for investment purposes.

Key Details

• Transaction date: May 15, 2026; price reported: $28.03 per share
• Shares withheld/disposed: 760; total value: $21,303 (approx.)
• Reason: Non-discretionary withholding for taxes related to a Feb 12, 2026 performance-based RSU grant that vested May 14, 2026
• Filing: This is an amended Form 4 (filed May 15, 2026) correcting the number of shares withheld and the price reported in the original Form 4
• Shares owned after transaction: The Form 4 reports the corrected total owned as of May 15, 2026 (the exact total ownership number is in the filing)

Context Tax-withholding (code F) on vested RSUs is routine and reflects the company collecting taxes due at vesting by withholding shares; it is not a discretionary sale that signals insider sentiment. The amendment corrects reporting details (number withheld and price) and does not indicate a change in the underlying vesting event.
