Rule 10b5-1 plan regulatory
"The sales reported herein were effected pursuant to a Rule 10b5-1 plan adopted on March 31, 2025."
A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.
GRAT financial
"nature_of_ownership": "By Jacob DeWitte GRAT No. 3""
weighted average price financial
"The price reported in Column 4 is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
definitive proxy statement regulatory
"please see the Issuer's most recent definitive proxy statement filed with the Securities and Exchange Commission."
A Definitive Proxy Statement is a detailed document that a company sends to its shareholders before a big meeting, like voting on important decisions. It explains what's being voted on and gives important information so shareholders can make informed choices. It matters because it helps shareholders understand and participate in key company decisions.
beneficially owned financial
"Represents securities beneficially owned by the Reporting Person's spouse."
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
