Robert Piconi

Robert Piconi is a declared insider of Energy Vault Holdings, Inc. (chief executive), with filings sourced from SEC (Form 4). Over a trading history stretching from 11 February 2022 to 30 September 2026, the count stands at 43 filings.

In open-market terms, that means 15 purchases worth €1.4M on one side and 13 sales worth €129k on the other. Purchases outweigh sales by €1.3M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 13 share grants and 1 option exercise. Since January 2026: 2 purchases and no sales on the market.

A typical purchase (the median) is worth €80k. Clusters matter here: 6 out of 15 purchases overlapped with buying by a colleague within 30 days. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. Looking at 15 purchases old enough to measure, the stock rose over the following 90 days in 67% of cases; the median change was +35.5%. This is a record of the past, not a forecast.

The record was last updated on 2 October 2026 with a share grant (€578k) in Energy Vault Holdings, Inc. The last insider purchase was made public on 1 April 2026, 200 days ago. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
