Exhibit 99.1

Viavi Solutions Inc.

Unaudited Pro Forma Condensed Consolidated Financial Information

At 12:01 a.m. Eastern Daylight Time on August 1, 2015, Viavi Solutions Inc. (“Viavi”), formerly known as JDS Uniphase Corporation (“JDSU”), completed the previously announced distribution of approximately 80.1% of the outstanding common stock of Lumentum Holdings Inc. (“Lumentum”) to Viavi’s stockholders (the “Distribution”). Concurrent with the Distribution, JDSU was renamed Viavi Solutions Inc. and, at the time of the Distribution, retained ownership of approximately 19.9% of Lumentum’s outstanding shares. Lumentum was formed to hold Viavi’s communications and commercial optical products business segment and the WaveReady product lines (“CCOP”) and, as a result of the Distribution, is now an independent public company trading under the symbol “LITE” on The Nasdaq Stock Market (“NASDAQ”). The Distribution was made to Viavi’s stockholders of record as of the close of business on July 27, 2015 (the “Record Date”), who received one share of Lumentum common stock for every five shares of Viavi common stock held as of the close of business on the Record Date and not sold prior to August 4, 2015, the ex-dividend date. Viavi commenced “regular-way” trading on August 4, 2015 on NASDAQ under the ticker symbol “VIAV.”

The following unaudited pro forma condensed consolidated statements of operations of Viavi for the nine months ended March 28, 2015 and for each of the years ended June 28, 2014, June 29, 2013 and June 30, 2012 are presented as if the Distribution had occurred as of July 3, 2011. The following unaudited pro forma condensed consolidated balance sheet of Viavi as of March 28, 2015 assumes that the Distribution occurred on March 28, 2015. The unaudited pro forma condensed financial statements are not necessarily indicative of Viavi’s results of operations or financial position had the spin-off been completed on the dates assumed. The assumptions used and pro forma adjustments derived from such assumptions are based on currently available information and such assumptions are believed to be reasonable under the circumstances.

The statements presented are intended for informational purposes only, and do not purport to represent what Viavi’s financial position and results of operations actually would have been had the Distribution occurred on the dates indicated, or to project Viavi’s financial performance for any future period. Beginning in the first quarter of fiscal 2016, Lumentum’s historical financial results for periods prior to the Distribution will be reflected in Viavi’s consolidated financial statements as discontinued operations.

The following unaudited pro forma condensed consolidated financial statements have been derived from Viavi’s historical consolidated financial statements for the years ended June 28, 2014, June 29, 2013 and June 30, 2012 and the interim unaudited period ended March 28, 2015. The unaudited pro forma condensed consolidated financial statements and the accompanying notes should be read in conjunction with (i) the audited consolidated financial statements and accompanying notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Viavi’s Form 10-K for the year ended June 28, 2014 and (ii) the unaudited condensed consolidated financial statements and accompanying notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Viavi’s Form 10-Q for the nine months ended March 28, 2015.

The “Historical” columns in the unaudited pro forma condensed consolidated statements of operations and in the unaudited pro forma condensed consolidated balance sheet reflects Viavi’s historical financial statements for the periods presented and does not reflect any adjustments related to the Distribution and related events.

The “Lumentum Separation” columns in the unaudited pro forma condensed consolidated statements of operations have been derived from Viavi’s audited consolidated financial statements and the related accounting records for the years ended June 28, 2014, June 29, 2013 and June 30, 2012, and the unaudited interim period ended March 28, 2015. The amounts reflect the financial results of CCOP, adjusted to include certain costs directly attributable to CCOP and to exclude Viavi corporate-level operating costs. These corporate-level operating costs were previously allocated to CCOP in Lumentum’s audited combined financial statements for the years ended June 28, 2014, June 29, 2013 and June 30, 2012, and the unaudited interim period ended March 28, 2015 which are included in Lumentum’s information statement dated July 16, 2015 (the “Information Statement”). The Information Statement has been filed as an exhibit to this Current Report on Form 8-K.

The “Lumentum Separation” column in the unaudited pro forma condensed consolidated balance sheet was derived from Viavi’s unaudited consolidated financial statements and the related accounting records as of March 28, 2015, adjusted to include certain assets and liabilities that were transferred to Lumentum pursuant to the contribution agreement. The information in the “Lumentum Separation” columns should be read in conjunction with Lumentum’s audited combined financial statements and notes thereto as of and for the years ended June 28, 2014, June 29, 2013 and June 30, 2012 and unaudited condensed combined financial statements and notes thereto as of March 28, 2015 included in the Information Statement.

Viavi Solutions Inc.

Unaudited Pro Forma Condensed Consolidated Financial Information

Notes to unaudited pro forma consolidated financial statements:

(a)         Reflects the removal of non-recurring transaction and pre-separation costs that are directly related to the separation of Lumentum from Viavi.

(b)         In connection with the separation, Viavi will make cash contributions so that Lumentum’s total cash amount as of the separation date is $137.6 million, subject to the requirements as set forth in the contribution agreement. For the purposes of the pro forma financials, based on Lumentum’s cash and cash equivalent balance of $10.6 million as of March 28, 2015, a pro forma adjustment of $127.0 million was reflected to reduce Viavi’s cash and cash equivalents and provide Lumentum with $137.6 million of total cash.

(c)          Viavi retained approximately 11.7 million shares, or approximately 19.9%, of Lumentum’s outstanding common shares that it will record at fair value. This investment is expected to be accounted for as available-for-sale securities under the authoritative guidance. For the purposes of the pro forma financial statements, the value of the Company’s investment in Lumentum was calculated using $21.15 per share, the closing stock price of Lumentum on August 4, 2015 which was the first day of trading.

(d)         The pro forma adjustment to stockholders’ equity reflects the net effect of the pro forma adjustments described above.
