Important caveats

When the abbreviation is part of a company’s official name, preserve that official spelling and punctuation rather than normalizing it.

Punctuation Boundary

Cambridge Business English shows forms including Inc., inc., and inc depending context, so punctuation is not a universal one-form rule.
