In order to have a "market" price and ticker symbol or ISIN (which is what I think you mean by "no one is mentioning the stock name") the stock must be listed on a market. Remember that the stock price is the last price someone paid for it on a stock market.
A symbol will be allocated by each stock market it trades on at or just before IPO; there is no need for one pre-IPO as no market data will exist for it. IPO (initial public offering) is the process of putting shares onto the market so until the IPO is complete the shares aren't marketable.
Since there isn't a market price for the stock how you value the stock is part accountancy and part alchemy. Since part of the stock value is share holder equity (= assets - liabilities) this can be calculated. The other part of the value is the net present value (NPV) of future cashflows, to calculate this for a pre-IPO stock you need more of a crystal ball and major guess work than is needed for other stocks as the large players, such as the investment banks, haven't priced it in yet.
