Gyroscope Therapeutics Postpones Initial Public Offering

Gyroscope Therapeutics Holdings plc ("Gyroscope"), a clinical-stage gene therapy company focused on treating diseases of the eye, today announced it has postponed plans for its initial public offering.

"In light of market conditions, we have decided to postpone our planned initial public offering," said Khurem Farooq, Chief Executive Officer. "Based on the positive feedback we have received from institutional investors on the strength of our science and investigational gene therapies, we believe it's in the best interest of our existing shareholders and employees to execute our IPO in more favorable market conditions. In the meantime, we are continuing to advance our clinical program for our investigational gene therapy, GT005, as well as our earlier stage pipeline."
