RSUs/PSUs financial

"Class A Common | 06/01/2026 | RSUs/PSUs | Issuer"

RSUs (restricted stock units) are promises by a company to give an employee shares after they meet time-based conditions, like staying for a set period; PSUs (performance stock units) only convert into shares if the company hits specific financial or operational targets. For investors, both can increase a company’s share count and signal how management is being paid—think of RSUs as a deferred paycheck and PSUs as a goal-based bonus that can affect future dilution and executive incentives.

10b5-1 Sales regulatory

"10b5-1 Sales for KERRY ACOCELLA ... Class A Common | 05/05/2026"

10b5-1 sales are pre-arranged stock-trading plans that let company insiders automatically buy or sell shares according to a fixed schedule or formula, even if they later learn confidential information. Think of it as setting up an automatic thermostat for trades: it creates a clear, documented path that can protect insiders from insider-trading accusations and gives investors a signal about predictable insider activity—though it can also simply be a way for insiders to diversify or raise cash.

Form 144 regulatory

"Filer Information | Issuer Information ... 144: Securities To Be Sold"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.
