grantor retained annuity trust financial
"The reported securities are directly held by a grantor retained annuity trust, of which the reporting person is the sole trustee and beneficiary."
A grantor retained annuity trust (GRAT) is an estate-planning tool where the person who creates the trust transfers assets into it but receives fixed cash payments (an annuity) from the trust for a set number of years; whatever remains after that term passes to designated beneficiaries. It matters to investors because it can shift future appreciation of assets out of the creator’s taxable estate—like putting an asset into a timed vending machine that pays you fixed amounts while any extra value that grows inside the machine goes to heirs with reduced gift or estate tax consequences.
Rule 10b5-1 trading plan regulatory
"The reported transaction represents a sale effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on November 17, 2025."
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
Class B Common Stock financial
"Each share of Class B Common Stock is convertible into one share of the Issuer's Class A Common Stock at any time, at the election of the holder."
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
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 $67.19 to $68.18, 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.
indirect ownership financial
"The reported securities are directly held by the Canis Major 2025 Family Trust LLC, of which the reporting person serves as manager."
