Note 17 – Convertible Senior Notes

In 2016, the Company issued $325 million aggregate principal amount of convertible senior unsecured notes that will mature on February 1, 2023 (the “Notes”). The Notes will bear cash interest at a rate of 3.75%, payable on February 1 and August 1 of each year, beginning on August 1, 2016. The Notes are not redeemable prior to maturity and are convertible into shares of Novavax common stock. The initial conversion rate for the Notes is 146.8213 shares of Novavax’ common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $6.81 per share of Novavax’ common stock, representing an approximately 22.5% conversion premium based on the last reported sale price of Novavax’ common stock of $5.56 per share on January 25, 2016.

In connection with the issuance of the Notes, the Company also paid approximately $38 million to enter into privately negotiated capped call transactions with certain financial institutions (the “capped call transactions”). 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 the Company’s 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 the Company’s 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 the Company’s 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.
