The ICO token is not what the company is worth. If you read their whitepaper, it is like people or donating ETH or Bitcoin for their project. The token can be worth 0 and also don't give any right in the company.
But thoses tokens are traded like it was the valuation of the company. I don't know why, but it is the rich investors who decide what is the worth of the token/coin. But it is not the real value of the company.
The company already got their funds at the ICO.
