Drafts William Arnold 4

What Happened
William Arnold, President of M-tron Industries (MPTI), reported three dispositions of derivative securities in April 2026 totaling 11,749 shares. Reported transactions:

• 3,600 shares disposed on 2026-04-06 at $0.00 (derivative)
• 7,609 shares disposed on 2026-04-13 at $0.00 (derivative)
• 540 shares disposed on 2026-04-14 at $0.00 (derivative)
  All three transactions are coded as sales (S) of derivative securities and were reported with a $0 price/value on the Form 4.

Key Details

• Filing date: 2026-04-28; Period of report listed as 2026-04-13. One transaction is dated 2026-04-14. The Form 4 was filed well after the typical 2-business-day deadline, so this appears late.
• Transaction dates/prices: 4/6/2026 (3,600 @ $0.00), 4/13/2026 (7,609 @ $0.00), 4/14/2026 (540 @ $0.00).
• Total shares disposed: 11,749; total reported cash value: $0.
• Shares owned after transaction: Not specified in the provided filing data.
• Footnotes: F1 details a stock option vesting schedule (30% on 4/4/2026, 30% on 4/4/2027, 40% on 4/4/2028). F2 notes a subscription-rights distribution (5 rights to buy one share at $59 when exercisable).

Context

• These are derivative-security dispositions (S = sale). The $0 reporting can occur for transactions involving derivative settlements, net exercises, transfers or other non-cash arrangements; the filing itself does not specify the exact mechanistic reason. Footnote F1 indicates recent option vesting on 4/4/2026, which may be related to the reported derivative disposals.
• This is a sale-oriented filing (not a purchase); sales are often routine (cashing out vested awards) but do not, by themselves, imply management view on company prospects.
