Rapport Therapeutics is talking up a $122 million IPO, the first in a return to public market interest since an earlier rush this year. The Third Rock epilepsy biotech is offering 8 million shares, with a range of $16 and $18. Assuming the $17 mid-range price, the offering could net as much as $136 million. The underwriters will have a chance to buy an additional 1.2 million shares. Rapport is expecting net proceeds to be $122 million after all is said and done based on the $17 price, or $141.1 million if the underwriters opt-in. The shares will list under the symbol RAPP. The company is also expecting an additional $16.7 million in net proceeds through a sale of shares to existing stockholders in a private placement happening at the same time.
Rapport will also put the money towards developing a long-acting injectable formulation of RAP-219 and advancing another TARPg8 AMPAR program called RAP-199 into phase 1. The rest of the money will go towards other R&D activities. The biotech's planned IPO was the first in a small resurgence of public offerings for the summer to come. Rapport was quickly followed by Actuate Therapeutics in late May.
