GT Advanced Technologies Inc. (NASDAQ: GTAT) (the “Company”) today announced the pricing of $205 million aggregate principal amount of its 3.00% Convertible Senior Notes due 2017. The Company has granted the underwriters an option to purchase up to an additional $15 million aggregate principal amount of the notes from the Company. The notes will mature on October 1, 2017, unless repurchased or converted in accordance with their terms prior to such date, and will bear interest at a rate of 3.00% per year, payable semiannually in arrears on April 1 and October 1 of each year, beginning on April 1, 2013. The notes will be convertible, under certain circumstances, into cash, shares of the Company’s common stock, or a combination of both, at the Company’s election, at an initial conversion rate of 129.7185 shares of the Company’s common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $7.71 per share of the Company’s common stock. The Company will not have the right to redeem the notes prior to maturity. The Company has also entered into convertible note hedge transactions with certain financial institutions, some of which are affiliates of the underwriters (the “Option Counterparties”) , which are intended to reduce its exposure under the notes to future increases in the price of the Company’s common stock. The Company has also entered into separate warrant transactions with the Option Counterparties, and the warrants have an exercise price that is approximately 67.5% higher than the closing price per share of the Company’s common stock on September 24, 2012. The issuance of the warrants could have a dilutive effect on the Company’s common stock to the extent that the market price exceeds the exercise price of the warrants. If the underwriters exercise their option to purchase additional notes, the Company may enter into additional convertible note hedge transactions and additional warrant transactions with the Option Counterparties.
