Restricted Stock Units ("RSUs") financial

"Represents Restricted Stock Units ("RSUs") acquired pursuant to the terms of the GCT Semiconductor Holding, Inc. ..."

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

GCT 2024 Omnibus Incentive Compensation Plan financial

"acquired pursuant to the terms of the GCT Semiconductor Holding, Inc. (the "Issuer") GCT 2024 Omnibus Incentive Compensation Plan."

vest financial

"The RSUs will vest on March 31, 2026, subject to continued service through such date."

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

Common Stock financial

"Each RSU represents the right to receive one share of common stock, par value $0.0001 per share ("Common Stock") of the Issuer"

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
