Restricted Stock Units financial

"Represents the number of shares of Class A Common Stock issued upon the vesting of restricted stock units ("RSUs")"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax withholding requirements financial

"Represents the number of shares of common stock withheld by the Company to satisfy tax withholding requirements in connection with the RSU vesting."

contingent right financial

"EACH RESTRICTED STOCK UNIT ("RSU") REPRESENTS A CONTINGENT RIGHT TO RECEIVE ONE SHARE OF COMMON STOCK UPON VESTING"

Exercise or conversion of derivative security financial

"transaction_code_description": "Exercise or conversion of derivative security"

tax-withholding disposition financial

"transaction_action": "tax-withholding disposition"

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.

What insider transaction did T Stamp (IDAI) CEO Gareth Genner report?

Did the T Stamp (IDAI) CEO buy or sell shares on the open market?

What do the RSU-related codes M and F mean in the T Stamp (IDAI) Form 4?

Code M indicates exercise or conversion of derivative securities, here RSUs converting into common shares. Code F indicates shares withheld by the issuer to cover tax liabilities, a non-market disposition typical for equity compensation vesting events.
