The reasons for contracting are numerous: the structure of a company`s shares is often found in the company`s statutes. Companies that offer several types of shares sometimes also have a series (Class A, Class B, Class C, etc.) that may be worth different amounts of money. For example, 100 Class A common shares may not be of the same value as 100 Class B shares. If your company sells shares to raise money, attract employees or grow the business, a share purchase agreement is essential. If you are in the initial phase of the letter of your business plan for a new business or if you have a start-up that needs investors, a share purchase contract is required to continue selling shares. Use our share purchase agreement (SPA) to register the purchase of shares and protect buyers and sellers. A share purchase agreement should be used whenever a person or company sells or buys shares in a company or another person or company. When buying all the shares of a company (100% of the shares), it is recommended to use the purchase of commercial agreements instead. The class of common or pre-weighted shares may affect the shareholder`s share of the company`s profits or the amount it receives when the company is liquidated and whether a shareholder has voting or non-voting shares, decides whether or not the shareholder has the right to vote at shareholder meetings. Remember that most companies will have common shares, but not all will have preferred shares. With regard to the fundamental content of the share purchase agreement, we should mention the most common clauses: the signature is therefore the date on which the parties sign the agreement and give their agreement on the legal transaction, that is, at the time of the execution of the contract. Stocks are heavily regulated by the federal government and municipalities. It is important that the share purchase agreement complies with all the rules and laws applicable to the sale of shares.
