A10 Networks (ATEN) General Counsel Weber Receives Stock Awards

What Happened

Weber Robert Scott (General Counsel) received stock awards from A10 Networks (ATEN) on February 12, 2026: 7,413 time‑based Restricted Stock Units (RSUs) and 7,413 Performance‑based Restricted Stock Units (PSUs). Both grants were awarded at $0 per share (typical for equity compensation awards) and therefore show $0 purchase price on the Form 4. This is an award/grant (code A), not a market purchase or sale.

Key Details

Transaction date: February 12, 2026; Form 4 filed February 13, 2026 (timely).
Awards: 7,413 RSUs (time‑based) + 7,413 PSUs (performance‑based) = 14,826 units total.
RSU vesting (F1): One‑third vests on each of the first three anniversaries of the Vesting Commencement Date (2/1/2026), contingent on continued service.
PSU terms (F2/F3): 7,413 PSUs vest only if specified VWAP performance milestones are met during any 100‑day trading period between Feb 12, 2026 and Feb 12, 2030. If a milestone is achieved, 50% of that tranche vests within 30 days of achievement and the remaining 25% vests on each of the first and second anniversaries of achievement, subject to continued employment.
Shares owned after the transaction: not reported in the provided excerpt of the filing.
Transaction codes: A = Award/Grant; derivative reporting indicates PSUs are contingent rights (not currently tradable shares).

Context

These awards are compensation‑style grants, not purchases or sales—so they reflect company compensation decisions rather than the insider buying or selling stock in the open market. PSUs are performance‑contingent: they only convert to actual shares if the specified price/volume conditions are met within the multi‑year performance window.
