This prospectus relates to the issuance by Innventure, Inc., a Delaware corporation, of up to an aggregate of 18,386,688 shares of ourcommon stock, par value $0.0001 per share (“Common Stock”) issuable upon the exercise of warrants to purchase shares of CommonStock, at an exercise price of $11.50 per share, which were converted from Learn CW Warrants (as defined in this prospectus) inconnection with the Business Combination (as defined herein) (the “Innventure Warrants”). We will receive the proceeds from anyexercise of any Innventure Warrants for cash, which amount of aggregate proceeds, assuming the cash exercise of all Innventure Warrants,would be $214.4million.
