Private-equity firm Apollo Global Management is looking to raise $300 million to $500 million in an initial public offering as early as this spring, CNBC said, citing unnamed sources.

CNBC said the size of the IPO has yet to be finalized, but Apollo has been discussing the listing plan with underwriters Goldman Sachs Group Inc., JP Morgan Chase & Co. and Bank of America Corp.

Apollo filed its first prospectus with the Securities and Exchange Commission three years ago and has amended it seven times since then, CNBC said.

Goldman Sachs has declined to comment, while Apollo, JP Morgan and Bank of America have yet to respond.
