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 3 share grants and 15 option exercises.
Most recently, on 5 January 2026, the filings show a share grant in Viking Therapeutics, Inc. The last purchase on record was published on 31 May 2018, which is 3,084 days ago. Typically, a trade is published a median of 1 day after it takes place. The legal deadline for a Form 4 is two business days after the transaction. 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.
