Pre-planned conversion-and-sale of 50,000 shares; large remaining position.

Gabriel Mecklenburg converted 50,000 Class B shares into Class A and sold all 50,000 Class A shares in open-market trades, at weighted average prices of $38.448 and $39.0167. The filing specifies these were executed under a Rule 10b5-1 plan adopted on December 1, 2025, indicating a pre-scheduled liquidity event rather than an opportunistic trade.

After the transactions, he held no Class A shares directly but retained 1,793,102 Class B shares directly and additional Class B shares through a GRAT and a family trust, representing 1,092,119 and 383,592 underlying Class A shares, respectively. The filing also references 944,250 performance stock units. In proportional terms, selling 50,000 shares while retaining millions of Class A–equivalent shares appears consistent with routine diversification or liquidity, with limited impact on overall alignment.

Rule 10b5-1 trading plan financial

"The sales reported in this line item were effected pursuant to a Rule 10b5-1 trading plan adopted..."

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..."

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.

Class A Common Stock financial

"Each share of Class B Common Stock is convertible into one share of the Issuer's Class A Common Stock..."

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.

performance stock units financial

"Excludes 944,250 performance stock units held by the Reporting Person."

Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
