The company intends to grant the underwriters a 30-day option to purchase up to an additional 270,000 shares of common stock to cover over-allotments. All of the shares are being offered by the company. Ceradyne has also announced that it is offering to sell $100 million aggregate principal amount of senior subordinated convertible notes due 2035 in an underwritten public offering. The company intends to grant the underwriters a 13-day option to purchase up to an additional $10 million of notes to cover over-allotments. Both offerings are subject to market and other conditions, and are not contingent on each other.
