earn-out shares financial

"Represents 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.

VWAP financial

"the 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.
