Upon closing of the Business Combination, the post-closing combined company will be renamed Tevogen Bio Holdings Inc.

Ryan Saadi, Chief Executive Officer of Tevogen Bio, commented, “We believe Tevogen’s patient-centric approach, which merges a focus on affordability with advanced science, is a blueprint for sustainable success in the current era of healthcare. I am pleased that, upon the closure of this transaction, investors will have the opportunity to participate in Tevogen’s mission to become the very first life science company offering commercially attractive and affordable personalized T cell therapies for large patient populations in virology, oncology, and neurology.”

Suren Ajjarapu, Chief Executive Officer of Semper Paratus, added, “Since its inception, Tevogen’s achievements have underscored the potential of its disruptive business model to achieve a shorter path to revenue compared to the industry average. With the receipt of notice from the SEC confirming the effectiveness of our registration statement, we are excited to have cleared a key milestone for the Transaction, which will see Tevogen become a publicly traded company with the opportunity to realize its full potential and enhance value for our stockholders.”

Tevogen Bio and Semper Paratus previously announced, on June 29, 2023, their execution of a definitive business combination agreement. The pro forma equity value of the portion of the combined company attributable to Tevogen stockholders is an expected $1.2 billion.
