Ronald C. Foster, a director of Advanced Energy Industries, reported the conversion/settlement of 2,313 restricted stock units (RSUs) into 2,313 shares on May 2, 2026. The Form 4 shows an exercise/conversion (transaction code M) and a corresponding disposition line with $0 proceeds, indicating the RSUs vested and converted into common stock rather than a cash sale.

Key Details

  • Transaction date: May 2, 2026; Form 4 filed: May 5, 2026.
  • Shares converted/received: 2,313 common shares (from RSUs). Reported price: $0.00 on disposition line (no cash sale).
  • Footnote F1: These RSUs were originally granted May 2, 2025 and vested on the one‑year anniversary; RSUs convert one‑for‑one into common stock.
  • Footnote F4: RSUs are not exercisable and have no expiration date (context on award terms).

Context

This transaction reflects routine vesting/settlement of equity compensation (an award converting to stock), not an open‑market purchase or sale. There were no proceeds generated from a sale at the time of conversion. Such vesting events are common for directors and do not, by themselves, indicate a buy or sell signal.
