PAION AG: HANA PHARM RECEIVES MARKET APPROVAL FOR BYFAVO IN GENERAL ANESTHESIA IN THE PHILIPPINES

• Byfavo^TM launch in the Philippines expected in the fourth quarter of 2023
• Hana Pharm's Byfavo^TM sales increased by 260% in South Korea in 2022

Aachen, Germany, 17. July 2023 – PAION AG (ISIN DE000A3E5EG5; Frankfurt Stock Exchange, Prime Standard: PA8K), a specialty pharmaceutical company with innovative compounds for use in outpatient and hospital sedation, anesthesia and critical care, announces that Hana Pharm, licensee of Byfavo^® for South Korea and Southeast Asia, has informed PAION that "Byfavo^TM 50mg (Remimazolam besylate)" has been approved by the Philippine FDA for the induction and maintenance of general anesthesia. Hana Pharm plans to launch the product in the Philippines in the fourth quarter of this year.

The approval of Byfavo^TM in general anesthesia in the Philippines is the first approval in the six Southeast Asian (SEA) countries. Hana Pharm expects this approval to have a positive impact on approvals in the remaining five Southeast Asian countries and contribute to increased sales in South Korea.

According to Hana Pharm, Southeast Asia is one of the fastest growing pharmaceutical markets. With an average annual growth rate of 6% to 9%, it is a highly attractive market compared to South Korea with an average annual growth rate of 5%. According to the Korea Health Industry Development Institute (KHIDI), the Philippines is forecast to grow at a rate of around 8.5% by 2023.

Hana Pharm further disclosed that its sales in South Korea increased by 260% in 2022 compared to 2021. A Hana Pharm representative stated: "With the recent approval obtained in the Philippines, we anticipate that it will contribute significantly to revenue growth through overseas markets, including the six Southeast Asian countries."

Taehong Choi, CEO at Hana Pharm, commented: "The approval obtained in the Philippines is a testament to Hana Pharm’s global business capabilities. We will make efforts to ensure the successful establishment and reputation of Byfavo^TM (Remimazolam besylate) as an anesthesia drug in the Philippines through its academic development. Taking advantage of the attractive Southeast Asian market, known as the 'Pharmerging Market,' we plan to further grow as a global pharmaceutical company."

"We are very pleased that our partner Hana Pharm has reached an important milestone with the approval of Byfavo^TM for general anesthesia and is thus able to start marketing in the Philippines soon. This underlines once again that the Asian market offers great potential for our product portfolio. We see that especially in the Asian countries Hana Pharm and our other partners are making good progress. Thus, we are optimistic that PAION will continue to expand in Asia in the field of anesthesia and critical care in the coming years," said Gregor Siebert, CEO of PAION AG.

PAION granted Hana Pharm exclusive rights to develop and commercialize Byfavo^® for the South Korean market in 2013. In 2020, the licensing rights in Southeast Asia followed. Under the agreements, PAION is entitled to royalties in the low double-digit percentage range in Hana Pharm's licensed territory.
