GARNREITER MICHAEL 4

What Happened

Michael Garnreiter, a director of Amtech Systems, Inc. (ASYS), had two reported derivative-related transactions: a grant of 2,839 restricted stock units (RSUs) on 2026-03-04 (acquisition, code A) and a conversion/exercise of 8,081 derivative units on 2026-03-05 (code M). The 8,081 shares show both an acquisition and a disposal on 2026-03-05 in the filing. All transactions are reported at a $0.00 price per share and no dollar amounts are shown.

Key Details

• Transaction dates and codes:
  • 2026-03-04 — Grant/award (A): 2,839 RSUs acquired @ $0.00
  • 2026-03-05 — Exercise/conversion (M): 8,081 shares acquired @ $0.00
  • 2026-03-05 — Exercise/conversion (M): 8,081 shares disposed @ $0.00
• Report filed: 2026-03-06 (Form 4 accession 0001193125-26-096467) — appears timely based on reported trade dates.
• Shares owned after transaction: Not specified in the filing.
• Footnote: F1 — each restricted stock unit represents a contingent right to receive one share of Amtech common stock.

Context

• RSUs (A) are awards that give a contingent right to receive shares in the future; footnote F1 confirms that each RSU corresponds to one share if/when settled.
• The M-code entries show a conversion/exercise event and the filing also reports a disposal of the same 8,081 shares on the same day; the Form 4 does not elaborate on the mechanics (e.g., sale, net withholding for taxes, or transfer).
• These transactions are compensation/derivative-related (awards and conversions) rather than open-market purchases or sales driven by investment decisions; they should be interpreted as insider compensation activity unless additional detail is disclosed.
