I don't know where it's cast in stone

But this might help.

In order to list under general NYSE standards, a company must satisfy minimum distribution requirements, market value requirements and financial standards:

Distribution. A company seeking to list existing securities or transfer to the NYSE must have at least 1.1 million publicly held shares and meet one of the following three criteria:

Have at least 400 holders of 100 shares or more and an average monthly trading volume of at least 100,000 shares for the most recent six months.
Have at least 2,200 total shareholders and an average monthly trading volume of at least 100,000 shares for the most recent six months.
Have at least 500 total shareholders, with an average monthly trading volume of at least 1 million shares for the most recent 12 months.
A company seeking to list in connection with its initial public offering (IPO), must have at least 400 holders of 100 shares or more and at least 1.1 million publicly held shares.

Market value. The aggregate market value of publicly held shares must be at least US$40 million for IPO companies, or US$100 million for companies seeking to list their existing securities or to transfer to NYSE. Additionally, the shares must have a closing price (or, if listing in connection with an IPO, an offering price) of at least US$4 per share at the time of listing.
