In connection with the Merger, all outstanding Legacy Ionetix common stock warrants were assumed by the Company and converted into warrants to purchase shares of the Company’s common stock, with the number of underlying shares and exercise price adjusted based on the Conversion Ratio. The converted warrants otherwise continued to be subject to substantially the same terms and conditions applicable to such warrants immediately prior to the Merger.
