JDSU Announces Repurchase at Option of Holders of 1% Senior Convertible Notes Due 2026

Milpitas, Calif., April 18, 2013 — JDSU (NASDAQ: JDSU and TSX: JDU) today announced that holders of its 1% Senior Convertible Notes due 2026 (CUSIP No. 46612J AD 3) (the “Notes”) have the right to surrender their Notes for purchase by JDSU pursuant to their option (the “Put Option”) under the Indenture governing the Notes, dated as of May 17, 2006, (the “Indenture”). The Put Option entitles each holder of the Notes to require JDSU to purchase all or any part of such holder’s Notes at a purchase price (the “Repurchase Price”) equal to 100% of the principal amount of the Notes plus accrued and unpaid interest thereon to, but excluding, the Repurchase Date. Pursuant to the terms of the Indenture, on May 15, 2013, JDSU will pay the semi-annual interest due on the Notes through May 14, 2013, to holders of record on May 1, 2013 of all Notes in the usual manner regardless of whether the Put Option is exercised with respect to such Notes. Interest on all Notes that are repurchased will cease to accrue interest on and after May 15, 2013 (the “Expiration Date”).

The opportunity to surrender Notes for purchase pursuant to the Put Option commences today and expires at 5:00 p.m., New York City time, on May 15, 2013. Holders may withdraw any Notes previously surrendered for purchase at any time prior to 5:00 p.m., New York City time, on May 15, 2013. In order to exercise the Put Option and receive the Repurchase Price, or withdraw Notes previously surrendered, a holder must follow the procedures set forth in the Issuer Repurchase Notice, which is being mailed to all registered holders of Notes.

None of JDSU or its board of directors or employees have made or are making any representation or recommendation as to whether or not any holder should surrender any Notes.
