Item 8.01 Other Events.

Eton was notified of a decision in the Paragraph IV litigation regarding cysteine hydrochloride injection. The court ruled to uphold Exela Pharma Science's patents. Eton strongly disagrees with the decision and expects Dr. Reddy's Laboratories to appeal the ruling. Eton sold the product to Dr. Reddy's Laboratories in June 2022, and Dr. Reddy's Laboratories is responsible for all legal activities. Eton could still receive a milestone payment if Dr. Reddy's Laboratories prevails on appeal and launches the product.
