Answer:
Cannot quote stock on Stock Exchange
A private limited company by definition will not be allowed to trade on stock exchanges like a public limited company would. This means that they will not be able to go into the stock market to seek additional funding if needed thereby reducing their chances of getting investment funds.
Number of shareholders limited.
Private limited companies face a limit on the number of people that can hold shares in the company. Some countries have different limits but generally the number of shareholders should be somewhere between 2 and 200.
This again restricts the amount that can be raised from issuing stock.
