Ciena Corporation plans a private offering of $2.0 billion aggregate principal amount of convertible senior notes due 2031, with an option for initial purchasers to buy up to an additional $300.0 million. The notes will be senior unsecured and fully guaranteed by certain domestic subsidiaries.
Ciena expects to use a portion of the net proceeds to fund convertible note hedge transactions and repurchase up to $140 million of its common stock. It intends to apply approximately $1.14 billion to repay its existing senior secured term loan and use the remainder for general corporate purposes, including supply chain investments.
In connection with the offering, Ciena expects to amend its credit agreement to extend the maturity of its $300 million revolving facility to October 24, 2030, adjust interest rate features linked to its total net leverage ratio, and provide increased flexibility for the note and hedge structures.
