Key Terms

Form 144, RSU Vesting, Issuer

3 terms

Form 144 regulatory

"Filer Information | 144: Filer Information 144: Issuer Information"

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.

RSU Vesting financial

"Securities To Be Sold Common Stock | 04/28/2026 | RSU Vesting"

RSU vesting is the process by which restricted stock units — a promise by a company to give shares to an employee — become actual, owned shares over time or when certain goals are met. Investors care because vested shares can dilute existing ownership when issued, and the timing of vesting affects when employees can sell shares, which can influence share supply, insider selling patterns, and company incentives.

Issuer regulatory

"RSU Vesting | Issuer | | | 23025 | 04/28/2026 | Compensation"
