Question about brand name in title

[BJack]

I know this has been covered a million times but I cannot find one related to mine as far as brand goes.

We have a 3 word company name (brand) and all three words are excellent keywords. We rank decent in google and other search engines, but I did not know if I should put our brand all together, or keep them spaced since I am using the keywords in the title in other places.

Our company name is ex. A B C

Title page is as follows and I am showing where our company name appears in the title for our pages. I am just not wanting to stuff the keywords in the title, although it is hard not to with our brand. I do not want to give out our company name. Below I am showing where part of our name appears in the title of pages. The (C) in the first part of the title is singular. Our name and brand for C is plural. I hope you understand. After 10 years in business we are redoing some things to make it even better. Moz Pro has been wonderful tool for us, the last 40 days.

Main Keyword B C | Secondary Keyword | A B C

Should it be

Main Keyword B C | Secondary Keyword | ABC

Thank you all!
