Nicholas M. Grindstaff

Nicholas M. Grindstaff is a declared insider at 3 companies (senior executive); the most frequent names are Sterling Infrastructure, Inc., Orbital Energy Group, Inc. and Quanta Services, Inc. The record holds 5 filings, for trades running from 10 May 2021 to 10 July 2026.

Every open-market trade on record is a sale: 1 sale worth €705k. Outside the open market, there are 4 share grants.

The latest filing, published on 14 July 2026, reports a share grant of €331k in Sterling Infrastructure, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 5 days. US insiders must file a Form 4 within two business days of a trade. 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.
