A company called Royalty Flow is raising capital for a percentage of the royalties from Eminem’s music catalog for those songs released during the period from 1999 to 2013. Popular Eminem albums released during this period include Slim Shady, Marshall Mathers LP, and The Eminem Show.

Eminem is the second best-selling male musician during the past 25 years. He sold more albums than any other hip-hop artist. So far, he sold more than 172 million albums.

Pitchfork says that Royalty Flow acquired the rights of up to 25 percent of the royalties by buying them from Jeff and Mark Bass, who were Eminem’s first producers and Joel Martin, who is their manager.

Royalty Flow’s capital raise is for $11 million up to $25 million for an initial public offering (IPO) to take the company public. After the company goes public, anyone can buy, sell, or trade shares in the company and thereby have a direct investment in the royalties from the Eminem catalog.

Royalty Flow is raising money by using Regulation A+ of the JOBS Act, which allows any investor to participate in the IPO. The company gives three reasons why they think the investment is potentially a good one. The first is the boom in royalty revenues now coming from streaming. The second is that these revenues are growing, and the third reason is that the company intends to acquire additional music catalog rights of other world-class musicians.

In the past, royalty rights deals have been made for the Beatles music catalog that was purchased by the late Michael Jackson, the catalog of David Bowie’s music, and many other well-known musicians.

The royalty rights owned by Royalty Flow are for Eminem songs; however, Eminem himself has denied any involvement in the deal. A representative from Eminem, quoted in Variety, said, “Eminem is not involved in any deals for the sale of recording royalties and has no connection to this company. The decision to offer the royalty stream for sale or otherwise was made independently by a third party who retains royalties for an early portion of his catalog and Eminem was not consulted.”
