stock options financial
"stock options granted under the 2017 Equity Incentive Plan of Forge Nano"
Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.
earn-out shares financial
"earn-out shares granted in connection with the Business Combination"
Earn-out shares are company shares promised to sellers or managers only if the business meets agreed future targets after a merger or acquisition, functioning like a performance-based payout instead of immediate cash. They matter to investors because they can dilute existing ownership, change future earnings prospects and reveal how confident buyers are about growth — like a conditional bonus that shifts payment and risk into the future.
performance stock units financial
"performance stock units, each representing a right to receive one share"
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
VWAP financial
"VWAP of the Common Stock equals or exceeds $15.00 per share"
VWAP, or Volume-Weighted Average Price, is a way to find the average price of a stock throughout the trading day, giving more importance to times when more shares are traded. It helps traders see the typical price and decide whether a stock is expensive or cheap compared to its average, similar to finding the average speed during a trip by giving more weight to times when you traveled faster or slower.
