Former Bruker Corp. (NSDQ:BRKR) executive Dirk Laukien and his half-brother Joerg Laukien — both directors at the Billerica, Mass.-based scientific instruments maker — late last week cashed in on another portion of their still-sizable stakes, each selling just under 540,000 shares of Bruker stock.
The Sept. 10 transactions went out at $13.27 a share, producing a combined $14.3 million in gross proceeds for the siblings.
