Btw., another consequence of the current higher level of share prices: Tesla's debt schedule would be lighter by ~4 billion dollars (they can pay in shares instead of cash) - a very large chunk of Tesla's long term debt would be eliminated in essence, right?
The longer Moody's is waiting with an upgrade of Tesla's debt, the more ridiculous their stance becomes.
Yes if they choose to pay in new shares they will both eliminate the debt and increase their cash balance.
For example, for the Mar 2021 bonds, if the stock price is at $450 in March 2021, convert holders will choose to convert their $1,380m bond into 3.8 million shares worth $1,725m. Tesla's call option hedge will be worth $345m and the warrant it sold would be worth 0.
Tesla can either choose to pay the bondholders $1,725m in cash or it can issue them 3.8m new shares. If it issues them 3.8m new shares, it will eliminate $1,380m debt off its balance sheet and also close its call options to raise $345m new cash on balance sheet. Alternatively it can choose to pay cash, here it will sell the calls and eliminate the debt and give the bondholders $1,725m, but cash balance would be depleted by $1,380m. Here it is quite likely they issue normal bonds to fund the $1,380m.
Alternatively, if the stock price is $600 in March 2021, the convert holders 3.8m shares will be worth $2,300m and Tesla's call option hedge worth $920m. The $561m strike warrants will also be in the money and Tesla will be required to issue 3.8m shares to the warrant holders at a share issue price of $561.
So here if Tesla chooses to repay the convert in cash. It will sell the calls, pay the convert holders $2,300m and deplete cash balance by $1,380m. It will then issue 3.8m new shares to warrant holders and receive $2,132m cash in return. So overall it will have eliminated $1,380m debt and increased cash balance by $752m while diluting stock by 3.8m new shares.
It can also choose double dilution and repay both the convert holders and warrant holders in new shares. In this case it will see 7.6m dilution, eliminate $1,380m debt and raise $920m + $2,132m = $3,052m cash.
