Brian J. Blaser

Brian J. Blaser, listed as chief executive, has filed trades across 3 companies (mainly through SEC (Form 4)), most often in QuidelOrtho Corp, Rockley Photonics Holdings Ltd and Quanterix Corp. Between 18 March 2022 and 13 February 2026, the trades on record add up to 10 filings.

Purchases make up the whole of the open-market record (5 purchases, €1.2M). Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 4 share grants and 1 option exercise. So far in 2026, the count stands at 1 purchase and no sales.

Half of the purchases are above €210k and half below. Clusters matter here: 1 out of 4 purchases overlapped with buying by a colleague within 30 days. Purchases made close together by different insiders form what is called a cluster. Ninety days after publication, 3 purchases show a median change of -17.6%, with the price up in 0% of them. These figures describe past trades and do not predict future prices.

Most recently, on 13 February 2026, the filings show an open-market purchase worth €210k in QuidelOrtho Corp. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
