- Acquisition Offer: Eli Lilly initiated a tender offer for Adverum on November 7, 2025, providing $3.56 per share in cash plus up to $8.91 in contingent value rights, totaling a potential $12.47 per share, significantly enhancing shareholder value.
- Funding Support: The Promissory Note signed with Lilly allows Adverum to access up to $65 million, of which $40 million has already been advanced, with an additional $25 million expected on December 5, 2025, to support clinical trials and operations.
- Liquidity Risk: Should the merger agreement be terminated, Adverum faces a liquidity crisis, unable to repay the Promissory Note, which could lead to bankruptcy, highlighting the urgency of this transaction.
- Board Recommendation: After an 18-month strategic review, Adverum's Board believes the transaction with Lilly is the best option, especially given the absence of other acquisition proposals, ensuring immediate liquidity and value for shareholders.
