Private equity firm TPG said on Tuesday it was seeking a valuation of up to $9.3 billion in its initial public offering in the United States.

The Fort Worth, Texas-based company plans to sell around 28.3 million shares priced between $28 and $31 each. It would raise about $877.6 million at the top end of that range.

Existing shareholders of TPG are offering roughly 5.59 million shares, the proceeds from whose sale will not go to the firm.

Founded in 1992 by David Bonderman and Jim Coulter, TPG was launched as Texas Pacific Group in Mill Valley, California. Its first major investment was in the then bankrupt Continental Airlines in 1993.

Its portfolio of investments includes Airbnb Inc, Burger King, Uber Technologies Inc and Spotify Technology SA. TPG has also sponsored multiple special-purpose acquisition companies.

J.P. Morgan, Goldman Sachs, Morgan Stanley, TPG Capital BD LLC and BofA Securities are the lead underwriters for the offering. The firm expects to list on the Nasdaq under the symbol "TPG."
