IPO research

Rainier Acquisition Corp is a newly offered Cayman Islands SPAC seeking $75.0 million before any over-allotment. It has no identified target, and the principal investor considerations are redemption/liquidation uncertainty, sponsor dilution, conflicts of interest and limited operating history.

The prospectus describes a $75 million SPAC IPO of 7.5 million units at $10.00 per unit, with a 24-month business-combination window and no selected target.
