More Information on That Rating Here in Investopedia (always coming in clutch for us) - https://www.investopedia.com/terms/b/b3-b.asp
"
B3/B- refers to the letter grades ratings agencies assign to companies, issuers, and securities that are considered speculative and carry a greater degree of risk than investment grade bonds. In the world of junk bonds, a B3/B- rating is about as low of a rating as most investors will accept."
So... you probably don't need me stating this - but,
not good. But hey, if Bitcoin hits $100k, they could really turn things around (assuming they don't sit here and leverage up way more debt in the meantime).
Moody's essentially made it clear they'd downgrade them further if they piled on anymore debt beyond this point (so this could be it for MS for a little while)
