Vlad Vitoc: trading record in brief
All filings by Vlad Vitoc on record concern MAIA Biotechnology, Inc., in the capacity of chief executive. We count 20 filings; the first trade dates from 1 August 2022 and the latest from 14 September 2026.
The open-market record is one-sided, with 20 purchases worth €268k and not one sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Since January 2026: 1 purchase and no sales on the market.
A typical purchase (the median) is worth €4,906. Measured against the company's value, the median purchase equals 0.026% of market capitalisation, across 3 purchases where it is known. 17 out of 18 purchases came within 30 days of a purchase by at least one other insider of the same company. When several insiders buy within a few weeks of each other, analysts speak of a cluster purchase. Ninety days after publication, 14 purchases show a median change of -33.4%, with the price up in 29% of them. Past outcomes like these are no guarantee of what comes next.
The latest filing, published on 15 September 2026, reports an open-market purchase of €86k in MAIA Biotechnology, Inc. Typically, a trade is published a median of 3 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
