Harry Quarls

Harry Quarls has filed trades across 2 companies (mainly through SEC (Form 4)), most often in ESS Tech, Inc. and Seadrill Ltd. Over a trading history stretching from 28 August 2023 to 13 October 2025, the count stands at 10 filings.

The open-market record is one-sided, with 6 purchases worth €308k and not one sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 3 share grants and 1 option exercise.

Half of the purchases are above €45k and half below. On 4 out of 6 purchases, another insider of the same company was buying within the same 30 days. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase.

On 15 October 2025 came the latest disclosure, a share grant in ESS Tech, Inc. The last purchase on record was published on 13 May 2024, which is 888 days ago. Typically, a trade is published a median of 3 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Source: insider filings from SEC (Form 4).
