Biles Linda M 4/A

What Happened

• Linda M. Biles, Executive Vice President — Finance of M-tron Industries (MPTI), reported sales of derivative securities (subscription Rights) in April 2026. The filing lists sales of 24,643 derivative units on 2026-04-09 and 2,700 derivative units on 2026-04-14, each reported at $0.00 per unit in the Form 4/A. This Form 4/A amends an earlier Form 4 to add a Rights sale on April 9 that was inadvertently omitted.

Key Details

• Transaction dates and reported amounts: 4/9/2026 — 24,643 derivative units (reported $0.00/unit); 4/14/2026 — 2,700 derivative units (reported $0.00/unit).
• Transaction type: Reported as sales (S) of derivative securities (subscription Rights), not direct common-stock open-market sales of shares.
• Shares owned after transaction: The amended filing corrected the ending beneficial-ownership balance; see the Form 4/A for the updated exact balance.
• Footnotes of note:
  • F1: A stock-option grant vests 30% on 4/4/2026, 30% on 4/4/2027, and 40% on 4/4/2028.
  • F2: On 3/30/2026 shareholders received one subscription Right per share; five Rights permit purchase of one common share at $59.00 when exercisable.
  • F3: This filing amends the original Form 4 (filed 4/16/2026) solely to add the April 9 sale of Rights that was left out and to correct the post-transaction ownership amount.
• Timeliness: The filing is an amendment; the original Form 4 was filed April 16 and this Form 4/A was filed April 29 to correct the omission.

Context

• These items are reported as derivative/Right transactions (not a straightforward stock buy or cash exercise). Subscription Rights were distributed to holders and can be sold or later used to purchase stock (five Rights per share at $59 if exercised).
• The amendment corrects reporting — amendments can affect how ownership totals are read but do not by themselves indicate intent or trading strategy.
