Form 144 regulatory

"NET filed a Form 144 indicating a planned sale of 55,000 shares"

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.

10b5-1 Sales Plan regulatory

"10b5-1 Sales Plan for THOMAS SEIFERT 101 Townsend Street"

A 10b5-1 sales plan is a written, prearranged schedule that company insiders use to buy or sell their employer’s stock under a U.S. securities rule, so trades occur automatically at set times or prices regardless of later private information. It matters to investors because it reduces the risk of insider-trading accusations and signals that certain insider trades were planned ahead—like putting transactions on autopilot—while still affecting share supply and market confidence.
