Securities Compliance Analyst

Form 144 records affiliate sale notices and recent dispositions by Paolo Tonucci.

Form 144 is a notice of proposed sale for restricted or control securities. The excerpt lists multiple small, dated sales of Common Stock in 2026 with per-transaction share counts and gross proceeds values. Timing and method of sale are not detailed in the excerpt.

Regulatory follow-up appears routine: subsequent filings or broker records will show whether the proposed sales were completed and under what method; absent those, the notice itself is an administrative disclosure.

Capital Markets Attorney

The filing shows transaction-level detail but no issuer proceeds or contractual terms.

The excerpt identifies acquisition dates for the reported shares and lists sale dates with gross proceeds amounts. It does not state any issuer receipt of proceeds or any offering mechanics. These notices typically accompany broker-assisted dispositions of restricted shares.

Watch for later confirmations or broker reports if confirmation of sale completion or Rule 144 eligibility is required; this excerpt alone does not confirm settlement details.

"144: Securities Sold During The Past 3 Months"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

restricted securities financial

"Acquired from issuer in private transaction"

Restricted securities are shares or other investment instruments that come with legal or contractual limits on when and how they can be sold, like stock given to founders or bought in a private offering. Think of them as assets in a locked box that can’t be freely traded until certain conditions — such as a waiting period, company registration, or specific approvals — are met. For investors this matters because restricted securities are less liquid and can affect timing, price, and perceived value when they eventually enter the market.

gross proceeds financial

"03/16/2026 | 16666 | 587989.81"

The total amount of cash a company receives from a financing event or sale before any fees, expenses, taxes or deductions are taken out. Investors watch gross proceeds because it shows the raw scale of new capital being raised—think of it as the paycheck amount before withholdings—which helps assess how much funding is available for operations, growth, debt payoff or how much shareholder dilution might occur once costs are removed.
