With 11 technology partnerships from new and existing partners signed since our IPO, our partnered portfolio continues to expand, further demonstrating the strength of our know-how and expertise, and recognising Arecor as a partner of choice for enhanced safe, efficacious and more convenient treatments that improve patient outcomes. These partnerships also provide near term revenue plus upside potential from future licensing opportunities."
