10b5-1 Sales Plan regulatory

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

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.

Exercise of Stock Options financial
