Insights

Securities Analyst

TL;DR: Insider sale executed under a 10b5-1 plan; disclosed quantity, price range and post-sale holdings; neutral near-term market signal.

The Form 4 shows a pre-arranged sale by CEO Timothy J. Mattke of 139,203 MGIC shares at a weighted average price of $26.5367, with transactions spanning $26.38 to $26.96. Because the trades were effected under a Rule 10b5-1 plan adopted on 05/06/2025, the transaction is documented as preplanned rather than opportunistic. The report also discloses continuing direct beneficial ownership of 1,100,994.401 shares. For investors, the disclosure improves transparency but does not, by itself, change company fundamentals.

Corporate Governance Expert

TL;DR: The sale was executed under a documented 10b5-1 plan, which mitigates governance concerns; the disclosed size merits monitoring but is not an immediate red flag.

The filing identifies Timothy J. Mattke as both CEO and a director and records a sale of 139,203 shares under a Rule 10b5-1 trading plan adopted on 05/06/2025. The filing provides a weighted average price and a full range of execution prices, and it states the remaining direct beneficial ownership of 1,100,994.401 shares. The use of an attorney-in-fact for execution is documented. From a governance standpoint, the disclosure of the plan date and price range supports compliance and transparency; no governance violations are reported in this filing.
