[Form 4] M-tron Industries, Inc. Insider Trading Activity

Rhea-AI Filing Summary

M-tron Industries, Inc. director Ivan Arteaga reported exercising warrants to buy additional common stock. On January 6, 2026, he acquired 35 shares of Common Stock at $47.50 per share through the exercise of 360 Common Stock Warrants, a derivative security with an exercise price of $47.50. After this transaction, he beneficially owned 873 shares of Common Stock and 4 Common Stock Warrants, all held directly. The filing explains that these additional shares were purchased under an Over-Subscription Privilege tied to a prior warrant dividend, which allowed holders who fully exercised their basic warrants to buy extra shares if other holders did not fully participate.
