Mary Gustanski

Mary Gustanski, listed as board member, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Hyliion Holdings Corp. and Amprius Technologies, Inc. The record holds 8 filings, for trades running from 11 October 2021 to 11 February 2026.

None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The latest filing, published on 13 February 2026, reports a share grant of €105k in Hyliion Holdings Corp. The median gap between a trade and its publication by SEC (Form 4) is 2 days. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
