NASDAQ / NMS requirements

Schweser says that NMS requires a company to have $1 million in pretax income. But don’t plenty of companies list on the NASDAQ even though they are unprofitable, e.g. tech companies?

I don’t know where Schwese got that from. I know that the requirement for listing has to do with capital and number of share owners, but nothing about income. Even for continued listing, the share price, not income, becomes the determining factor. That’s what I recall about that. Dreary
