performance-based restricted stock financial
"Represents performance-based restricted stock, which may be earned between 0% and 200%"
Shares granted to employees or executives that are held back and only become actual, tradable stock if the company meets predefined performance targets; until those goals are met the shares cannot be sold. Think of it like a bonus held in escrow that’s released only when specific results are achieved — investors watch these awards because they tie management pay to company outcomes, can dilute existing shareholders when released, and signal how confident or incentivized insiders are to meet growth or profitability goals.
adjusted EBITDA financial
"based upon the Issuer's actual performance as compared with an adjusted EBITDA target"
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.
2-for-1 stock split financial
"the Issuer effected a 2-for-1 stock split of its common stock"
stock dividend financial
"2-for-1 stock split of its common stock in the form of a stock dividend"
A stock dividend is when a company gives its existing shareholders extra shares instead of cash. It’s like receiving more pieces of the same pie rather than a bigger piece of money, which can increase the number of shares you own but usually doesn’t change the total value of your investment right away. Investors care about it because it can signal the company's growth and affect the stock’s price.
