The company is going public. Enterprise financing. I invested money. If the listing fails. Is my money ruined?

If you buy internal stocks, the failure of stock listing generally has no impact on the company. Listing is for refinancing, and the original shares can be listed and circulated. If you can't go public, you can't just buy and sell. Your only loss is the liquidity of funds. If the company grows well, you can also get dividends.
