- F1. Performance-Based Restricted Stock Units that were previously reported on February 13, 2026, 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 12, 2026 and February 12, 2030. The second achievement date occurred on April 27, 2026, as certified by the compensation committee of ATEN, resulting in 65,758 units meeting the appropriate performance-based conditions. However, these shares remain subject to time-based vesting conditions and will therefore vest as to one-half (1/2) on May 14, 2026 and an additional one-fourth (1/4) on each of the first and second anniversaries of April 27, 2026, subject to continued employment. These shares are reflected on Table I.
- F2. The amount of securities beneficially owned following the reported transaction has been corrected to reflect a clerical error in the previous filing on May 6, 2026. The correct number of shares meeting the appropriate performance-based condition for this award reported on the Form 4 filed by the reporting person on May 6, 2026 should have been 65,758, not 65,753, as previously reported.

The second achievement date occurred on May 6, 2026, as certified by the compensation committee of ATEN, resulting in 63,406 units meeting the appropriate performance based conditions. However, these shares remain subject to time-based vesting conditions and will therefore vest as to one-half (1/2) on May 14, 2026 and an additional one-fourth (1/4) on each of the first and second anniversaries of May 6, 2026, subject to continued employment. These shares are reflected on Table I.

Performance-based Restricted Stock Units financial
"Performance-Based Restricted Stock Units that were previously reported on February 13, 2026, each of which represents a contingent right to receive one share of common stock"
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
"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"
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
"transaction_action: "tax-withholding disposition" and transaction_code_description: "Payment of exercise price or tax liability by delivering securities""
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.
derivative exercise/conversion financial
"transaction_action: "derivative exercise/conversion" with transaction_code_description: "Exercise or conversion of derivative security""
beneficially owned financial
"The amount of securities beneficially owned following the reported transaction has been corrected to reflect a clerical error"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
