Nuburu, Inc.: what insiders have been doing
Nuburu, Inc. is a listed company. Its directors and officers file their transactions with SEC (Form 4). The last twelve months, up to 18 October 2026, brought 2 filings signed by 1 insider.
The flow runs one way only: 1 insider bought (1 purchase totalling €1.3M) and nobody sold on the market. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. At €1.3M, the purchase published on 22 April 2026 by Zamboni Alessandro is the largest of the period. Those buying include 1 chief executive.
The last purchase on record was published on 22 April 2026, which is 179 days ago.
Across the 5,458 companies tracked on its exchange, the median is 22 filings; at 2 filings, this issuer sits below that mark. Since 2022, the database holds 2 purchases and 4 sales by insiders of the company.
For comparison within the same market, see the insider buying recorded at GameStop Corp. and Heico Corp. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
