Thomas Caulfield

This profile gathers the share dealings of Thomas Caulfield across 3 companies, led by Western Digital Corp, Sandisk Corp and USA Rare Earth, Inc. Over a trading history stretching from 6 July 2021 to 1 October 2026, the count stands at 13 filings.

Not one of the filings records a straightforward purchase or sale on the market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

Most recently, on 5 October 2026, the filings show a share grant in USA Rare Earth, Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
