Novavax Prices $300 Million of Convertible Senior Notes Due 2023 - Seite 2

In connection with the pricing of the Notes, Novavax also entered into privately negotiated capped call transactions with certain financial institutions (the option counterparties). The capped call transactions are expected generally to reduce the potential dilution upon conversion of the Notes in the event that the market price per share of Novavax' common stock, as measured under the terms of the capped call transactions, is greater than the strike price of the capped call transactions, which initially corresponds to the conversion price of the Notes, and is subject to anti-dilution adjustments generally similar to those applicable to the conversion rate of the Notes. The cap price of the capped call transactions will initially be $9.73 per share, which represents a premium of approximately 75% based on the last reported sale price of Novavax' common stock of $5.56 per share on January 25, 2016, and is subject to certain adjustments under the terms of the capped call transactions. If, however, the market price per share of Novavax' common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call transactions, there would nevertheless be dilution upon conversion of the Notes to the extent that such market price exceeds the cap price of the capped call transactions. If the initial purchasers of the Notes exercise their over-allotment option, Novavax expects to enter into additional capped call transactions with the option counterparties.

Novavax expects that, in connection with the capped call transactions, the option counterparties or their respective affiliates will enter into various hedging transactions, including (without limitation) derivative transactions with respect to Novavax' common stock and/or to purchase Novavax' common stock concurrently with or shortly after the pricing of the Notes. This activity could impact the market price of Novavax' common stock or the Notes at that time, and could result in a higher effective conversion price for the Notes. In addition, the option counterparties and/or their respective affiliates may, from time to time, modify their hedge positions by entering into or unwinding various hedging positions, including (without limitation) derivative transactions with respect to Novavax' common stock and/or by purchasing or selling Novavax' common stock or other securities of Novavax in secondary market transactions. This activity could also impact the market price of Novavax' common stock or the Notes, which could affect the value of the shares that a holder of Notes receives upon conversion of the Notes.
