Q – How is this different from a traditional IPO?

A – Going public through a SPAC is similar to a traditional IPO, in that at the close of the transaction, the newly combined company is expected to be listed on the NYSE under a new ticker symbol. A SPAC is not an operating company but rather an entity designed to take operating companies, such as Mirion, public by first raising a pool of capital in its IPO, then investing those proceeds into the selected operating company through a merger. This process allows Mirion to benefit from certain flexibilities and advantages that are not available in a traditional IPO with underwriters. Several other growth companies have recently gone public through a SPAC.
