Restricted Stock Units financial

"On July 15, 2025, the Company granted Mr. Stinchcomb 2,400,000 restricted stock units (RSUs)..."

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.

tandem dividend equivalent rights financial

"2,400,000 restricted stock units (RSUs) with tandem dividend equivalent rights under the 2020 Omnibus Incentive Plan."

adjusted free cash flow financial

"achieving 40% revenue growth and 35% adjusted free cash flow growth for the full year 2025 compared to 2024..."

Adjusted free cash flow is the amount of money a company generates from its operations after accounting for essential expenses and investments, like maintaining or upgrading equipment. It shows how much cash is truly available to grow the business, pay debts, or return to shareholders, helping investors see the company's financial health more clearly.

performance-based financial

"The RSUs granted are performance-based, subject to the Company achieving certain stock price or financial performance goals."

weighted average price financial

"The price reported in Column 4 is a weighted average price."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
