Robert P. Ragusa

Filings by Robert P. Ragusa span 3 companies, the busiest being GRAIL, Inc., Twist Bioscience Corp and Alamar Biosciences, Inc. In total, 19 filings cover trades dated from 8 February 2022 to 1 September 2026.

Every open-market trade on record is a sale: 10 sales worth €13.4M. The rest of the record consists of 9 share grants. In 2026 alone, the filings show no purchases and 3 sales.

On 3 September 2026 came the latest disclosure, a share grant in Alamar Biosciences, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
