Section 8 — Other Events

Item 8.01. Other Events.

Bruker Corporation (“Bruker” or the “Company”) has been advised that Robyn L. Laukien, the former spouse of Bruker’s President and CEO Frank H. Laukien, is in the process of selling up to 800,000 of her shares of Bruker common stock in open market transactions as part of her plans for estate planning and portfolio diversification. Robyn Laukien has owned all economic rights over these shares for over ten years, and has sole investment authority over such shares.

Frank Laukien has held a voting proxy over Robyn Laukien’s shares of Bruker common stock for over ten years, which continues to be in existence for the remaining over 1.04 million shares of Bruker common stock that Robyn Laukien is expected to continue to own. Frank Laukien is not selling any Bruker shares that are directly owned by him and is not a participant in these transactions.

The Company has been informed that Robyn Laukien’s sale transactions commenced on May 29, 2019. As a result of the voting proxy granted to Frank Laukien, sale transactions effected by Robyn Laukien will be reported on Form 4 reports filed by Frank Laukien with the U.S. Securities and Exchange Commission. It is expected that Robyn Laukien’s remaining shares of Bruker common stock will continue to be reported as indirect holdings on Frank Laukien’s Form 4 reports during the remaining term of the voting proxy.
