When an offer is made, then books are opened and there is an "audit" done to see if what has been given out in public methods i.e. (K-8), etc. (form list here https://www.sec.gov/forms) is true. Also, finances are looked out, and all aspects of the business are investigated.

What happens if Elon finds that there was lying going on... He can back out of the deal, with all his money and all the information that they found in the audit.

Not saying this will happen, but would be interesting if it did.
