restricted stock units financial

"service-based 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-based options financial

"performance-based options"

adjusted EBITDA financial

"revenue and adjusted EBITDA targets"

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.

Remarks:

In March 2026, the Board approved a multi-year equity compensation program consisting of service-based restricted stock units (the "RSUs") and performance-based options (the "Options") granted to Mr. Rubin intended to align executive compensation with long-term stockholder value creation and incentivize extraordinary growth in revenue and adjusted EBITDA relative to our historical growth rates. Only the RSUs reflected above are currently subject to Section 16 reporting because the Options have performance vesting criteria, which are based on revenue and adjusted EBITDA targets, have not been achieved.
