A Stock Subscription Agreement is a legal contract between an investor (subscriber) and a company that grants the subscriber the right to purchase stock in the company at a set price. The agreement outlines the terms and conditions of the subscription, including the amount of stock being offered, its price, payment details, and any restrictions or warranties regarding the sale. It also includes contact information for both parties, so that the agreement can be enforced in the event of a breach. Investing in stocks has long been one of the best ways to build wealth, so make sure you fully understand your Stock Subscription Agreement before signing it.
