EPCOS launches 7 year convertible bond

NOT FOR RELEASE IN THE UNITED STATES, CANADA OR JAPAN

EPCOS is launching a convertible bond issue of approximately Euro 121-128 million today. The convertible bond has a maturity of 7 years and cannot be called for the first 5 years, callable thereafter subject to a 150 per cent trigger. The convertible bond is offered with a coupon of 2.5% to 3.0% and a conversion premium of 60% to 70%. The coupon and conversion premium will be set at final pricing, which is expected to occur today. The convertible bond will be issued by a Dutch finance subsidiary and guaranteed by EPCOS AG. It is expected to be rated BBB by S&P.

EPCOS intends to list the convertible bond on the Luxembourg stock exchange. The convertible bond will be placed with institutional investors outside the US, Canada and Japan in reliance on Regulation S and will not be rule 144A eligible. Deutsche Bank is Sole Bookrunner on the convertible bond offering.

EPCOS is issuing the convertible bond to benefit from the attractive financing opportunity available in the current convertible market given the low interest rate and high volatility environment. The proceeds of the issue will be used to refinance existing indebtedness and extend EPCOS’ debt maturity profile. The offering will allow EPCOS to increase its financial flexibility.
