Your cash on hand, money in the bank, and investments (purchased shops and facilities, shelves, skill upgrades, R&D upgrades, product quality upgrades, warehouse upgrades, etc.) make up your company value.
Cryptocurrency investments, the value of products stored in the logistics warehouse and contract garage upgrades are not added to your company value. Since the money spent there is not calculated, these investments may negatively affect your company value.
The interest portion of loan debts and your tax debts will also reduce your company value.
When you sell shops and facilities, the upgrades made to them are not refunded, so your value decreases. In addition, some of these facilities are sold for only 70% of their value, so keep in mind that selling them may reduce your company value.
If you plan to sell all your facilities and transfer the money to a cooperative or another place in order to Become a Legend, remember that this will not work. Your company value will be recalculated again at the moment you Become a Legend.
