Insights

Securities Counsel

Routine Form 144 sale notification with recent holder dispositions.

The filing lists proposed or brokered resale activity for Common Stock and identifies a broker-dealer. It records per-trade share counts and corresponding gross proceeds for trades on 03/19/2026 and 04/01/2026.

These notices are procedural: they signal intended or reported sales but do not by themselves change ownership records. Subsequent transfer filings or settlement confirmations will show final results.

Form 144 regulatory

"144: Securities To Be Sold"

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.

broker-dealer financial

"Fidelity Brokerage Services LLC 900 Salem Street Smithfield RI"

A broker-dealer is a licensed firm or individual that both executes trades on behalf of clients (acting as a broker) and buys or sells securities for its own account (acting as a dealer). Investors care because broker-dealers provide the plumbing of markets — they place orders, hold or move cash and securities, offer research or advice, and their stability and fees directly affect trade execution, costs, and the safety of client funds; think of them as a combined travel agent and taxi for your investments.

proposed resale regulatory

"144: Securities To Be Sold"

gross proceeds financial

"47615 | 1235080.72"

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.
