How many Veeco (VECO) shares were sold in total by the Kiernan family trust?

The reporting shows 35,000 shares of Veeco Instruments common stock sold indirectly through a family trust. These sales were split across five separate transaction rows, each at different weighted-average price levels on August 10, 2026, all coded as open-market sales.

Were John P. Kiernan’s VECO sales direct or indirect holdings?

All reported sales involved indirect ownership described as “By Family Trust.” This means the transactions related to shares held through a family trust associated with Veeco’s chief financial officer, rather than directly held personal share accounts in his own name.
