Brenna McGibney, Chief Administration Officer at Trupanion (TRUP), has filed 87 Form 4 transactions, all in the single company. The aggregate picture is one of automatic dispositions rather than discretionary selling. Her total sell value across all filings is $107,956.30, with zero open-market purchases and zero acquisitions. Every transaction in the recent window carries code F (shares withheld to cover tax) or code M (option exercise), both of which are mechanical events tied to equity compensation vesting.
The recent activity clusters around three dates. On August 25, 2026, McGibney had five F-transactions totaling $9,952.96, paired with five M-transactions valued at zero. On August 22, 2026, she had three F-transactions totaling $98,265.44, again paired with three M-transactions at zero. The May 25, 2026 batch shows five F-transactions totaling $7,519.84 with five M-transactions at zero. The August 22 figure dominates the total, representing roughly 91% of her entire sell value across all 87 filings.
The pattern shows no buying bias. McGibney has not made a single open-market purchase in the data, and her only sell-side activity consists of tax withholding on exercised options. The dollar values are modest for an executive at a public company, and the timing aligns with vesting schedules rather than market windows. The direction is consistent: she accumulates no new shares through purchases, and her disposals are formulaic, tied to the cost of exercising options.
