FAQ

What insider transaction did HOLX SVP of Human Resources report?

Ms. De Walt reported shares withheld to cover taxes on vested restricted stock units. On January 30, 2026, 4,416 Hologic common shares were withheld at $74.93 per share, reflecting a non-open-market tax payment mechanism rather than a discretionary share sale.

How many HOLX shares does the reporting person own after this transaction?

After the reported tax withholding, the insider directly beneficially owns 7,603 Hologic common shares. This figure reflects her remaining holdings following the 4,416 shares withheld to satisfy tax obligations connected to the settlement of previously granted restricted stock units.

Why was this HOLX Form 4/A amendment filed on February 3, 2026?

The amendment was filed solely to attach the correct Power of Attorney. An incorrect Power of Attorney was previously attached, so this amended filing corrects that administrative error while leaving the originally reported transactions and share amounts unchanged.

Were the transactions in this HOLX Form 4/A new or previously reported?

The transactions were previously reported on the original Form 4 filed February 3, 2026. This amendment does not revise the transaction details; it only replaces the incorrect Power of Attorney that accompanied the earlier submission with the correct version.

What does transaction code F mean in the HOLX insider filing?

Transaction code F indicates shares were withheld to pay taxes on equity awards. In this case, 4,416 Hologic shares were withheld in connection with the settlement of restricted stock units for which service-based vesting conditions had already been satisfied.

Does the HOLX insider hold the reported shares directly or indirectly?

The filing shows the 7,603 Hologic shares as directly owned. The ownership form is marked as “D” for direct, and there is no indicated indirect ownership vehicle such as a trust or partnership associated with these reported common stock holdings.
