5 terms
Rule 10b5-1 Plan regulatory
"The transactions reported in this Form 4 were effected pursuant to a Rule 10b5-1 Plan adopted by the Reporting Person on February 19, 2026."
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.
Restricted Stock Units ("RSUs") financial
"A portion of these securities are Restricted Stock Units ("RSUs"). Each RSU represents a contingent right to receive one share of the Issuer's Class A Common Stock."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
beneficial ownership regulatory
"The Reporting Person may be deemed to have beneficial ownership over the securities held by the trust."
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
Annuity Trust financial
"These shares are held directly by the Mark L. Reinstra 2022 Annuity Trust for which the Reporting Person serves as trustee."
weighted average price financial
"The price reported in column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $55.35 to $56.19, inclusive."
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.
