restricted stock units financial
"Each restricted stock unit represents the right to receive, at settlement, one share of Class A common stock."
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.
2022 Omnibus Equity Incentive Plan financial
"On March 31, 2025, the Reporting Person was granted 110,122 restricted stock units ("RSUs") pursuant to the terms of the Issuer's 2022 Omnibus Equity Incentive Plan"
volume weighted average price financial
"at an exercise price of $2.52 per share, which was the volume weighted average price of the Issuer's Class A common stock for the five days immediately preceding March 31, 2026"
The volume weighted average price (VWAP) is a way to measure the average price of a security, such as a stock, over a specific period, taking into account how many units were traded at each price. It’s similar to calculating the average cost of items bought when some are more frequently purchased than others. Investors use VWAP to assess whether a security is being bought or sold at a fair price during trading.
tax withholding financial
"Represents the shares held by the Company to satisfy tax withholding requirements on vesting of restricted stock units."
Tax withholding is the practice of taking a portion of a payment—such as wages, dividends, or sale proceeds—before it reaches the recipient and sending that portion to the tax authority as an advance on the recipient’s eventual tax bill. For investors it matters because withholding reduces immediate cash received and affects after‑tax returns, estimated tax payments, and whether you may owe more or receive a refund when taxes are finally calculated, like having a small automatic savings set aside for your tax bill.
Change in Control financial
"in connection with or within the 24 months following the consummation of a Change in Control (as defined in the Plan and the relevant award agreement)"
A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.
