I can't imagine that anything is going to be known right away, never mind an investor/group of investors that is going to come/swoop in and save a company that might not be financially viable and unfortunately, in light of what has happened, the company is more than likely not financially viable. I think they have run out of money to operate. They have burned through all the cash and there has been no other interest from any other investors thus, the only solution was to "cease operations."
I also can't help but to think of the Shark Tank when they ask for numbers and they get something like;
"We have sold $30,000,000 worth of Redshifts."
"How much did it cost to produce that $30,000,000?"
"$70,000,000"
"What do you now need the $50,000,000 for?"
"So we can produce and sell the 300 ordered bikes for $3,600,000 as well as for the promotion of all the events we have been entering, operating costs, salaries . . ."
I can see the investors, all of them going over all of the details regarding Alta Motors and all of them ending up with an "And with that, I'm out."
Lastly, the decision to cease operations has to have been the last resort, the worst case scenario that the ownership wished to avoid at all costs. If there is no clear path to profitability and the cost to put a bike in a customers hands is more than the bike is being sold for . . . . I can't see those in charge of Alta Motors saying or thinking 'Lets cease operations for now. Send everyone home. Shut down the employment section of the website. It will be good for business. It will get our name out there and generate MORE interest. It will be good for business in the long run.'
Just like the old joke about boat building, "How does one make $1,000,000 in the boatbuilding business? Start with $2,000,000. "
The (cash) burn-rate just has/had to be so much more than the amount of money being taken in by the sales of the bikes.
