Spencer D. Armour III: trading record in brief
Spencer D. Armour III is a declared insider at 3 companies (senior executive); the most frequent names are ProPetro Holding Corp., Viper Energy Partners LP and Viper Energy, Inc. The record holds 72 filings, for trades running from 16 March 2017 to 19 May 2026.
On the open market, the record shows 1 purchase worth €99k and 20 sales worth €4.8M. Taken together, the sales exceed the purchases by €4.7M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Other entries cover 13 share grants and 37 option exercises.
On 21 May 2026 came the latest disclosure, a share grant in Viper Energy, Inc. The last purchase on record was published on 16 March 2023, which is 1,315 days ago. Filings reach the SEC (Form 4) feed a median of 1 day after the trade. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
