What this transaction means for investors
Last December, BioMarin Pharmaceutical (NASDAQ:BMRN) offered to acquire Amicus Therapeutics for $14.50 per share in cash. We don’t know exactly when CIBRA Capital bought heaps of Amicus shares during the first quarter. At the beginning of January, the stock was trading for around $14.30 per share. If CIBRA bought around that time, it stands to earn $0.20 per share if the transaction completes as anticipated.
Buying a stock priced slightly below its anticipated acquisition price is called merger arbitrage. This biotech deal is about as certain to complete as intended as deals get. Last December, the Boards of Directors of both companies unanimously recommended Amicus’ shareholders vote to adopt the agreement. Federal regulators rarely stick their noses into M&A deals for companies such as Amicus, which currently markets recently launched rare disease drugs.
While merger arbitrage is not an unusual practice for large firms, making Amicus CIBRA’s largest position was a bold move. If the deal doesn’t complete as expected, Amicus’ stock price could fall hard.
