There are lots of ways to do this, but I would recommend against using an icon like the one you have chosen (which could be platform specific). The concept of
more information is a bit abstract to represent with an icon that can easily translate across cultures.
If the information is to be shown in a overlay panel, then a downward arrow should be suitable:
This approach is how StackExchange displays more user information quickly in an overlayed panel:
Unless clicking the company name does something else, I would make clicking the company name or the arrow show the overlay panel.
If the arrow is not clear enough, I would add some text. Note that clicking
more info or the arrow should trigger the overlay panel:
If the infromation is to be on it's own screen in the application, then it is better to just be explicit and use a button:
In this case, there is no mistake and confusion as to how the user can get more information about the company. You should also style the button to suit your application.
