Walter S. Woltosz (board member) discloses dealings in Simulations Plus, Inc. to SEC (Form 4). In total, 125 filings cover trades dated from 21 January 2016 to 6 October 2026.

Both buying and selling appear: 1 purchase worth €1.2M, against 77 sales worth €43.1M. No amount is published for 1 filing, which the totals therefore leave out. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 30 share grants and 4 option exercises. 2026 to date brings no purchases and 2 sales.

The record was last updated on 6 October 2026 with a transaction (€52.8M) in Simulations Plus, Inc. The latest purchase dates back some time: it was published 2,247 days ago, on 26 August 2020. Typically, a trade is published a median of 1 day after it takes place. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
