Saniona (OMX: SANION), a clinical-stage biopharmaceutical company focused on neurological and psychiatric disorders, today announces that it has agreed to sell its entire shareholding in AstronauTx Ltd ("AstronauTx") to existing AstronauTx investors for GBP 3.36 million (SEK 44.5 million) in cash. Saniona received the shares in August 2026 when AstronauTx exercised its option to acquire worldwide rights to ATX0926. The transaction does not affect Saniona's rights under the collaboration, including potential milestone payments of up to USD 172 million and tiered royalties.
The purchase price will be paid in cash upon completion of the transaction, which is expected by the end of November 2026. The proceeds provide additional non-dilutive funding and further strengthen Saniona's financial position as it advances SAN2465 and SAN2668 into Phase 1 clinical development.
"With SAN2465 and SAN2668 approaching clinical development, our priority is to allocate capital to our wholly owned programs," said Johnny Stilou, Chief Financial Officer of Saniona. "The sale strengthens our financial flexibility and provides non-dilutive funding to support our clinical development plans."
In Saniona's interim report for the third quarter of 2026, the shareholding will be valued at the agreed sale price. The fair value has been assessed in conjunction with the agreed sales price. The resulting non-cash adjustment will be recognized as a financial item and will not affect the income previously recognized in connection with the option exercise.
About the AstronauTx-Saniona Collaboration
In July 2023, Saniona and AstronauTx entered into a research collaboration and option agreement to discover novel treatments for Alzheimer's disease and other neurodegenerative conditions by modulating a novel, undisclosed ion channel target.

Saniona is eligible to receive milestone payments of up to USD 172 million, comprising up to USD 97 million in development and regulatory milestones and up to USD 75 million in commercial milestones, in addition to tiered royalties on net sales of any products commercialized by AstronauTx under the collaboration.
