Rule 10b5-1 trading plan regulatory

"Sales were affected pursuant to Rule 10b5-1 trading plan dated 7/1/2025"

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.

Restricted Stock Units (RSUs) financial

"Shares reported include unvested Restricted Stock Units (RSUs)"

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

Performance Stock Units (PSUs) financial

"Shares reported include unvested ... Performance Stock Units (PSUs)"

Performance stock units (PSUs) are a form of executive or employee pay that promise company shares only if pre-set performance goals are met over a defined period; think of them as a bonus paid in stock that arrives only when the company hits agreed targets. Investors watch PSUs because they affect the number of shares outstanding (dilution) and reveal how management’s pay is tied to financial or operational results, aligning incentives with shareholder outcomes.
