at a time when debt was cheap and when Genzyme’s share price was depressed, having fallen from a 2008 peak of $83.25
to $47.16 in June 2010. Genzyme’s depressed share price reflected manufacturing problems that had lowered sales of its
best-selling products. Genzyme continued to recover from the manufacturing challenges that had temporarily shut down
operations at its main site in 2009. The plant is the sole source of Genzyme’s top-selling products, Gaucher’s disease
treatment Cerezyme and Fabry disease drug Fabrazyme. Both were in short supply throughout 2010 due to the plant’s
that the Genzyme shareholders would accept the offer rather than risk seeing their shares fall to $50. The shares, however,
traded sharply higher at $70.49 per share, signaling that investors were expecting Sanofi to have to increase its bid.
Viehbacher said he might increase the bid if Genzyme would be willing to disclose more information about the firm’s
ongoing manufacturing problems and the promising new market potential for its multiple sclerosis drug.
In a letter made public on August 29, 2010, Sanofi indicated that it had been trying to engage Genzyme in acquisition
that the firm was worth at least $80 per share. He based this value on the improvement in the firm’s manufacturing
operations and the revenue potential of Lemtrada, Genzyme’s experimental treatment for multiple sclerosis, which once
approved for sale by the FDA was projected by Genzyme to generate billions of dollars annually. Despite Genzyme’s
refusal to participate in takeover discussions, Sanofi declined to raise its initial offer in view of the absence of other bidders.
Sanofi finally initiated an all-cash hostile tender offer for all of the outstanding Genzyme shares at $69 per share on
The CVR helped to allay fears that Sanofi would overpay and that the drug Lemtrada would not be approved by the
FDA. Under the terms of the CVR, Genzyme shareholders would receive $1 per share if Genzyme were able to meet
certain production targets in 2011 for Cerezyme and Fabrazyme, whose output had been sharply curtailed by viral
contamination at its plant in 2009. Each right would yield an additional $1 if Lemtrada wins FDA approval. Additional
payments will be made if Lemtrada hits certain other annual revenue targets. The CVR, which runs until the end of 2020,
included a “top–up” option granted by the Genzyme board to Sanofi. The “top–up” option would be triggered when Sanofi
acquired 75% of Genzyme’s outstanding shares through its tender offer. The 75% threshold could have been lower had
Genzyme had more authorized but unissued shares to make up the difference between the 90% requirement for the short-
form merger and the number of shares accumulated as a result of the tender offer. The deal also involved the so-called dual-
track model of simultaneously filing a proxy statement for a shareholders’ meeting and vote on the merger while the tender
offer is occurring to ensure that the deal closes as soon as possible.
Discussion Questions
1. The deal was structured as a tender offer coupled with a “top up” option to be followed by a backend short
form merger. Why might this structure be preferable to a more common statutory merger deal or a tender offer
followed by a backend merger requiring a shareholder vote?
