Use a subfolder URL's like http://americanbank.com/
Only purchase new domains to protect company's name do not do it to rank and pressure during geo-targeting ( like you, for instance, you may in some cases THIS IS NOT ONE that I know of need a Russian IP and TLD to rank in Russia) So if you do not need to rank outside the United States just by the .net .org .com 's)
Using a subfolder will increase the domain and page authority as opposed to using the some domain that will be treated somewhat like a new domain by Google. There are advantages and disadvantages to each however if you want to rank you want to use subfolders primarily if you want to separate your site into different branches, and maybe some of them are for landing pages and some are private for content that is sensitive in nature want to use a subdomain.
An example of how much more power you can get out of the site by using a subfolder versus subdomain John Doherty an extraordinary SEO did this to hot pads here's a large photo below

should not redrect me to americanbank.com/business (unless for very good reason)
It appears you may be keyword stuffing your URLs. Maybe not intentionally I am not blaming you of anything but be careful Of the word business, it's not needed that many times.
You have a big redirect problem you should not use 302 redirects to the homepage (try it using this https://varvy.com/tools/redirects/ ) you have a very slow page load time as well unfortunately https://varvy.com/pagespeed/

However I can tell you that for things you want to rank for a subfolder is better than a subdomain. Hope I was of help, Thomas
