This is a leveraged buyout.
That means that $13 Billion was borrowed from Morgan Stanley to make this deal happen, and Twitter is the owner of that debt. Estimates are ~$1.3 Billion / year in interest payments (the most risky $3 Billion is unsecured loans, expected to be CCC-rated, and CCC-rated debt is around 16% right now). So I think 10% is a reasonable estimate for what this financing will cost.
In 2021, Twitter made... _NEGATIVE_ 200-million bucks.
So... yeah. Add $1.3 Billion of interest payments on top of that, and I think we got a problem here folks. Another note: TWTR's revenue (mostly advertisements) is $5 Billion/year. I really dunno where they're gonna find $1.3 Billion/year from.

What Musk bought here is a white elephant. It will cost tons of money just to stay afloat, let alone "make money" or even "retain value". If Elon Musk holds onto this and "only" loses a few dozen billion over the next few years, I think he'd have done a good job. I have no expectation that TWTR will remain a $44 Billion company over the next decade. Selling the company off for $20 Billion 5 years from now (IE: a $24 Billion loss) would be a herculean effort as it is IMO.
