It's usually a good idea to talk with your co-owners or directors about your and their future plans to give you time to talk through issues such as how you will realise your investment and when this will happen.
In a private company, you may be required to offer your shares to the existing shareholders. Alternatively, you may need to discuss plans to prepare the business for sale to a third party.
If you will also be retiring, there may well be other issues you need to discuss, such as succession planning and whether you will retain any involvement after you retire.
