LUDWIG MICHAEL M 4

What Happened

• Michael M. Ludwig, a director of Amtech Systems, converted/exercised derivative awards and disposed of stock. On 2026-03-04 he was granted 2,839 restricted stock units (RSUs). On 2026-03-05 the filing shows an exercise/conversion of 8,081 derivative units acquired and, on the same date, a disposition of 8,081 shares. All transactions list a $0.00 price, meaning no cash purchase price was reported (these were conversions/awards rather than open-market purchases).

Key Details

• Transaction dates and types:
  • 2026-03-04: Grant/award of 2,839 RSUs (code A) at $0.00 (derivative).
  • 2026-03-05: Exercise/conversion of derivative for 8,081 shares (code M) acquired at $0.00.
  • 2026-03-05: Exercise/conversion of derivative for 8,081 shares disposed at $0.00.
• Report filed 2026-03-06 covering period ending 2026-03-04 — filing appears within the standard two-business-day window.
• Shares owned after the transactions: not specified in the Form 4 filing.
• Footnote: F1 — each restricted stock unit represents a contingent right to receive one share of Amtech common stock.

Context

• The $0.00 price and the filing footnote indicate these were derivative awards/RSU-related conversions rather than cash purchases. The filing shows the converted shares were immediately disposed of (same-day acquisition and disposition of 8,081 shares); the Form 4 does not state the reason for the disposition (e.g., sale to cover taxes or a cashless exercise).
• This filing documents awards and conversion activity by a director; it does not, by itself, indicate an ongoing buy or sell decision about the company’s stock.
