NuVasive, Inc. Prices $350 Million Convertible Senior Notes Due 2017

SAN DIEGO, CA--(Marketwire - June 22, 2011) - NuVasive, Inc. (NASDAQ: NUVA) (the “Company”), a medical device company focused on developing minimally disruptive surgical products and procedures for the spine, announced the pricing of $350 million principal amount of 2.75% Convertible Senior Notes due 2017 (the “notes”) in an underwritten public offering. NuVasive has also granted the underwriters an option to purchase up to $52.5 million of additional notes solely to cover over-allotments. The offering is scheduled to close on Tuesday, June 28, 2011, subject to satisfaction of customary closing conditions. BofA Merrill Lynch and Goldman, Sachs & Co. are acting as joint book-running managers for the offering.

The notes will pay interest semiannually at a rate of 2.75% per annum. The notes will be convertible at the option of the holders into cash, shares of the Company’s common stock or any combination thereof at the Company’s election, upon the occurrence of certain events and during certain periods. The Company may only deliver shares of its common stock if it has received stockholder approval for an increase in the total number of authorized shares of its common stock sufficient to permit the Company to settle conversions of the notes and of the preferred stock issuable upon exercise of the warrants described below in shares of its common stock, and for authorization of such conversions of the preferred stock. Absent such approval, the Company would be required to satisfy any conversion obligations solely in cash. The Company intends to solicit such stockholder approval after the closing of this offering. The notes will be convertible at an initial conversion rate of 23.7344 shares of common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $42.13 per share, subject to adjustment upon the occurrence of certain events. The initial conversion price represents a conversion premium of approximately 30% over the last reported sale price of $32.41 per share of the Company’s common stock on the NASDAQ Global Select Market on June 22, 2011.

NuVasive estimates that the net proceeds from the offering will be approximately $340.7 million after deducting the underwriters’ discounts and commissions and estimated offering expenses, assuming no exercise of the underwriters’ over-allotment option.

NuVasive intends to use the net proceeds for general corporate purposes and to repurchase up to $230 million of its 2.25% Convertible Senior Notes due March 2013. The Company may consider possible strategic acquisitions of, or investments in, companies, technologies, products or assets, however, the Company has no present commitments or agreements to enter into any potential acquisitions or investments.

NuVasive also entered into convertible note hedge transactions with one or more of the underwriters or their affiliates (the “counterparties”) and intends to use a portion of the net proceeds from this offering to pay for the cost of the convertible note hedge transactions. The Company estimates that the cost of the convertible note hedge transactions, taking into account the proceeds from the sale of the warrants described below, will be approximately $28.0 million. The convertible note hedge transactions are intended to reduce the Company’s exposure to potential cash payments and/or (if the Company has received the stockholder approval described above) the dilution experienced by the Company’s stockholders upon any conversion of the notes. The Company also entered into separate warrant transactions with the counterparties that will be exercisable into a number of shares of a new series of the Company’s preferred stock, called the Series A participating preferred stock, based on the amount, if any, by which the market price per share of the Company’s common stock exceeds the strike price of the warrants during a measurement period at the maturity of the warrants. The Series A participating preferred stock will convert into shares of the Company’s common stock if the Company receives the necessary stockholder approval. If the Company has not received such stockholder approval before the warrant transactions are settled, the shares of Series A participating preferred stock will accumulate cash dividends at a specified dividend rate for as long as such shares remain outstanding. The warrant transactions will have a dilutive effect on the Company’s common stock if the market value per share of the Company’s common stock exceeds the applicable strike price of the warrants and the Company has received the necessary stockholder approval. However, subject to certain conditions, the Company may elect to settle the warrants in cash. If the underwriters exercise their over-allotment option, the Company may enter into additional convertible note hedge and warrant transactions.

In connection with establishing their initial hedge of these transactions, the counterparties and/or their respective affiliates expect to enter into various derivative transactions with respect to the Company’s common stock concurrently with, or shortly after, the pricing of the notes. These activities could have the effect of increasing or preventing a decline in, or could adversely affect the price of the Company’s common stock concurrently with or following the pricing of the notes.

In addition, the counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivative transactions with respect to the Company’s common stock or by selling or purchasing the Company’s common stock or other securities linked to the Company’s common stock in secondary market transactions following the pricing of the notes (and are likely to do so following during any observation period relating to a conversion of the notes). The effect, if any, of any of these activities on the market price of the Company’s common stock will depend in part on market conditions and cannot be ascertained. Any of these activities could adversely affect the price of the Company’s common stock and that of the notes or could have the effect of increasing or preventing a decline in the price of the Company’s common stock.

This announcement is neither an offer to sell nor a solicitation to buy any of the securities described herein and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.
