Cayson Acquisition Corp. said late Thursday it priced its initial public offering of 6 million units at $10 per unit.

Underwriters have been granted a 45-day option to buy up to 900,000 additional units, the blank-check firm said.

The units are expected to begin trading this Friday under the ticker symbol, "CAPNU."

Each unit comprises one ordinary share and one right entitling its holder to receive one-tenth of one ordinary share. Once the securities comprising the units begin trading separately, the rights are expected to list under the ticker, "CAPNR," while the shares are expected to list under the ticker symbol, "CAPN."
