A Common Stock Purchase Agreement with Vesting is a contract between a company and a shareholder outlining the terms and conditions of the purchase of shares of common stock with vesting. Vesting refers to the gradual acquisition of rights to shares of stock purchased by the shareholder over a period of time. This type of agreement is often used in early-stage investments in companies that are not yet publicly traded. The agreement outlines the amount of stock to be purchased by the shareholder, the vesting period, and the rights and obligations of the company and the shareholder. The vesting period is typically set forth in the agreement and can span from a few months to several years depending on the terms of the agreement. During the vesting period, the shareholder will gradually become entitled to the full amount of the shares purchased. The company must issue the purchased shares to the shareholder at the end of the vesting period. There are two main types of Common Stock Purchase Agreement with Vesting: cliff vesting and graded vesting. Cliff vesting means that all the purchased shares are vested at the same time, usually at the end of the vesting period. Graded vesting refers to a vesting schedule which allows the shareholder to acquire rights to the purchased shares over time, usually in increments of 25%. The Common Stock Purchase Agreement with Vesting is an important document for both the company and the shareholder, as it outlines the terms and conditions of the purchase and helps to protect the interests of both parties.
