Why Dynavax Shares Dropped

Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shareholders of biopharmaceutical company Dynavax (NAS: DVAX) are having a no good, very bad day as its stock is down 23% following the announcement of a secondary offering.

So what: Choosing to market its hepatitis B drug Heplisav independently means Dynavax needs cash. Today it took its money-raising efforts to the market in the form of a 17.5 million share offering that priced at $4.25 -- a clean 17% below yesterday's closing price. If that wasn't enough of a beating for shareholders, CEO Dino Dina, who has helmed the ship since 1998, noted that he would be stepping down. The market doesn't like uncertainty, and today we're getting a three-course meal of it.

Now what: Everything is really riding on the success or failure of Heplisav; and as we've learned from Dendreon (NAS: DNDN) with its prostate cancer treatment Provenge and Human Genome Sciences' (NAS: HGSI) lupus drug Benlysta, launching a drug is just as important as getting it approved by the Food and Drug Administration. Today's cash-raising effort is a necessary evil. Dynavax chose to go it alone and must raise the necessary cash to support its marketing efforts. Personally, I'm less worried about the secondary offering as I am about a longtime CEO leaving. Too many unanswered questions for my liking, if you ask me.
