time-based vesting provision financial

"Includes shares that have a time-based vesting provision."

forward split financial

"3-for-1 forward split of its Common Stock effected on April 2, 2026."

A forward split increases the number of a company’s shares by exchanging each existing share for multiple new shares, so each investor owns more pieces while their overall ownership stake and the company’s value stay the same. Think of cutting a pizza into more slices: each slice is smaller but you still have the same total; for investors this lowers the per‑share price, can make the stock feel more affordable, and often boosts trading activity and accessibility.
