Restricted Stock Units financial

"On April 3, 2023, the Reporting Person was granted 20,000 Restricted Stock Units"

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.

Performance Units financial

"Each Performance Unit represents a contingent right to receive one share"

Performance units are company awards that become valuable only if specified business targets are met; they typically convert into shares or cash when performance goals are achieved. Think of them like a conditional bonus that turns into stock only if the company hits agreed milestones, so they align managers’ incentives with shareholders’ interests and can affect future share count, executive pay expense, and investor returns.

Earned Performance Units financial

"Represents one-third of the total 46,106 "Earned Performance Units""

Adjusted EBITDA financial

"based upon the Issuer's achievement against a target "Adjusted EBITDA" goal for fiscal year 2023"

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

Total Revenue financial

"and the Issuer's achievement against a target "Total Revenue" performance goal for fiscal year 2023"

Long-Term Incentive Plan financial

"under the terms of the Issuer's 2023 Long-Term Incentive Plan"

A long-term incentive plan is a company program that pays executives or employees with stock, options, or cash tied to multi-year performance goals, where the rewards become theirs only after meeting conditions over time. Think of it as a delayed bonus or retirement-style reward that aligns employees’ interests with shareholders by encouraging them to boost long-term value; investors watch these plans because they affect pay costs, share dilution and management incentives.
