A10 Networks (ATEN) CFO Caron Michelle Elizabeth Receives RSU & PSU Award

What Happened

Caron Michelle Elizabeth, Chief Financial Officer of A10 Networks (ATEN), received two equity awards on February 12, 2026: 5,978 Restricted Stock Units (RSUs) and 5,978 Performance-based Restricted Stock Units (PSUs). Both awards are reported at a $0 acquisition price (typical for compensation grants), so no cash changed hands.

Key Details

Transaction date: 2026-02-12; Form 4 filed 2026-02-13 (timely).
RSU grant: 5,978 RSUs (footnote F1). Vesting: one-third of the total RSUs vests on each of the first three anniversaries of the Vesting Commencement Date (2/1/2026), subject to continued service.
PSU grant: 5,978 PSUs (footnotes F2, F3). Each PSU is a contingent right to one share; vesting depends on achieving specified VWAP-based performance milestones during any 100-day trading period between 2/12/2026 and 2/12/2030. If a performance milestone is met, 50% of that tranche vests within ~30 days of achievement, and the remaining 50% vests 25% on each of the first and second anniversaries of the milestone, subject to continued employment.
Reported price: $0.00 per share (award). No immediate sale or purchase of shares occurred.
Shares owned after the transaction: not specified in the provided excerpt of the filing.
No 10b5-1, tax-withholding, or late-filing notes included in the provided information.

Context

RSUs and PSUs are standard forms of executive compensation. RSUs vest with continued service; PSUs add a performance condition, so they only convert to shares if the company hits specified stock-price milestones over defined windows. These grants do not represent an immediate sale or purchase of shares and are not direct insider buying/selling signals.
