- F1. Performance-Based Restricted Stock Units were previously reported on February 10, 2025, each of which represents a contingent right to receive one share of common stock of ATEN, with vesting subject to the achievement of specified levels of the volume weighted average closing prices of a share of ATEN common stock during any one hundred (100) day trading period between February 6, 2025 and February 6, 2029.

Performance-Based Restricted Stock Units financial
"Performance-Based Restricted Stock Units were previously reported on February 10, 2025, each of which represents a contingent right"
Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.
volume weighted average closing prices financial
"with vesting subject to the achievement of specified levels of the volume weighted average closing prices of a share"
An average of a security’s closing prices over a chosen period where each day’s closing price is given more weight when more shares were traded that day. It tells investors the price level that reflects the most trading activity, so it smooths out days with little volume and highlights prices where market participants actually acted — like finding the busiest price on a shopping receipt rather than a price from an empty store.
tax-withholding disposition financial
"Includes 987 shares and 943 shares automatically withheld, on a non-discretionary basis, for tax purposes"
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.
time-based vesting conditions financial
"However, these shares remain subject to time-based vesting conditions and will therefore vest as to one-half"
