BALL FREDERICK 4

What Happened Frederick Ball, a director of Advanced Energy Industries, received an award of 587 restricted stock units (derivative securities) on May 7, 2026. The RSUs were granted as the equity portion of the non‑employee directors' retainer under the company's omnibus incentive plan. The grant has a $0 purchase price (award), so there was no cash paid by the insider.

Key Details

• Transaction date: 2026-05-07; Transaction type/code: Award (A) — 587 RSUs granted at $0.00.
• Vesting: The RSUs vest on the one‑year anniversary of the grant (May 7, 2027) contingent on continued service as a director (see footnote).
• Exercisability/expiration: RSUs are not exercisable and do not have an expiration date (per filing footnote).

Context This was a routine equity grant to a non‑employee director as part of board compensation, not a market purchase or sale. RSU awards align pay with future service/retention and do not represent immediate share ownership until vested; they are common director compensation and do not by themselves indicate a buy or sell signal.
