Form 144 regulatory

"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.

Restricted Stock Lapse financial

"Common | 12/17/2025 | Restricted Stock Lapse | Guardant Health, Inc."

Equity Compensation financial

"175 | 12/17/2025 | Equity Compensation"

Equity compensation is pay given to employees, executives or contractors in the form of company ownership—such as stock, stock options or restricted shares—rather than just cash. It matters to investors because it can align workers' incentives with shareholders (like paying someone in slices of the same pie they help grow), but it also increases the number of shares outstanding and company expenses, affecting ownership percentages and earnings per share.

Employee Stock Option Exercise financial

"08/05/2026 | Employee Stock Option Exercise | Guardant Health, Inc."

Broker Payment for Cashless Exercise financial

"950 | 08/05/2026 | Broker Payment for Cashless Exercise"
