NEWS RELEASE

Amada Signs Definitive Agreement to Purchase Preferred Stock of Subsidiary of Lumentum Holdings Inc. once JDSU Separation is Complete

Milpitas, Calif., May 13, 2015 – JDSU (NASDAQ: JDSU) announced today that it has signed a definitive agreement with Amada Holdings Co., Ltd. of Japan, a manufacturer of machine tools for metal fabrication, to purchase up to $40 million of preferred stock of a subsidiary of Lumentum Holdings Inc., the publicly-traded company that will result from the planned spin-off of the CCOP business unit from JDSU. The spin-off is expected to happen in the third calendar quarter of 2015 and the final amount of Amada’s investment will be determined based on initial trading of Lumentum Holdings Inc. common stock.

“We are honored that Amada has committed to invest in our business as we progress towards becoming our own publicly-traded company,” said Alan Lowe, president of CCOP at JDSU and CEO-designate of Lumentum.

“We look forward to continued collaboration as we have for more than eight years,” said Mitsuo Okamoto, president and CEO of Amada.

About the Agreement

Upon initial trading of Lumentum Holdings Inc. common stock, Amada will purchase from JDSU Series A Preferred Stock in a wholly-owned subsidiary of Lumentum Holdings Inc. The preferred stock may be converted into shares of common stock of Lumentum Holdings Inc. commencing on the second anniversary of the closing of the stock purchase (absent a change of control or similar event in Lumentum Holdings Inc.) using a conversion price calculated based on a 125 percent of the volume weighted average price per share of Lumentum Holdings Inc.’s common stock in the five trading days following the spin-off. Cumulative dividends will accrue at the annual rate of 2.5 percent, but will be paid only when and if declared by the Board of Lumentum Holdings Inc. The investment is contingent upon the consummation of the spin-off and is also subject to other customary closing conditions. No preferred stock will be offered to other parties, including the public. The transaction is expected to close in the second week following the spin-off, which JDSU has previously announced it intends to effect in the third calendar quarter of 2015. Further terms of the proposed transaction are set forth in a stock purchase agreement that will be filed as an exhibit to Lumentum Holdings Inc.’s Registration Statement on Form 10 with the U.S. Securities and Exchange Commission.
