Biotechnology Value Fund (BVF) has extended its tender offer for the outstanding shares of Avigen Inc (Nasdaq: AVGN).

We’ve been following AVGN (see archived posts here) because it’s a net cash stock (i.e. it’s trading at less than the value of its cash after deducting all liabilities) and specialist biotechnology activist fund BVF has been pushing it to liquidate and return its cash to shareholders. MediciNova Inc (NASDAQ:MNOV) has made an offer for AVGN that we think represents a clever way for AVGN’s stockholders to receive cash equivalent to that which they would receive in a liquidation (less $7M to be paid to MNOV) with the possibility for “an extraordinary, uncapped return” if MNOV is successful post-merger. We estimate AVGN’s cash at around $1.22 per share (BVF estimates $1.20 per share), which is around 20% higher than AVGN’s $1.01 close yesterday.
