Bumble (BMBL) has filed a preliminary prospectus late Tuesday for the sale from time to time of up to 58.6 million Class A common shares by the selling stockholders, Blackstone (BX) and Whitney Wolfe Herd, Bumble founder and chief executive officer.

This includes up to 21.2 million Class A shares that Bumble may issue from time to time to the selling stockholders upon exchange of an equal number of common units representing limited partnership interests in Buzz Holdings, its operating partnership, according to the filing.

Bumble will not receive any proceeds from the sale of the shares by the selling stockholders, but it has agreed to pay certain registration expenses, per the regulatory filing.
