Jon C. Biro

Jon C. Biro has filed trades across 3 companies (mainly through SEC (Form 4)), most often in Exterran Corp, Perma-Pipe International Holdings, Inc. and Harte Hanks Inc. In total, 9 filings cover trades dated from 4 March 2016 to 24 June 2026.

Not one of the filings records a straightforward purchase or sale on the market. Because grants and exercises are largely decided by remuneration plans, they are not counted as purchases here.

The record was last updated on 26 June 2026 with a share grant in Perma-Pipe International Holdings, Inc. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
