Item 7.01 Regulation FD Disclosure.

As previously announced, on April 28, 2015, Spectrum Brands Holdings, Inc. (“SB Holdings”; NYSE: SPB), a majority-owned subsidiary of HRG Group, Inc. (“HRG”; NYSE: HRG), entered into an Agreement and Plan of Merger (the “AAG Merger Agreement”) with Armored AutoGroup Parent Inc. (“AAG”), Ignite Merger Sub, Inc., an indirect wholly owned subsidiary of SB Holdings, and Avista Capital Partners II GP, LLC, as representative for the shareholders and optionholders of AAG. Under the AAG Merger Agreement, SB Holdings will acquire AAG for a purchase price of approximately $1.4 billion (subject to customary adjustments for cash, debt, net working capital and transaction-related expenses described in the AAG Merger Agreement), which will be paid entirely in cash (the “AAG Acquisition”). SB Holdings expects to finance the $1.4 billion cash purchase price of the acquisition and related fees and expenses through a combination of new debt and approximately $500 million of SB Holdings common stock, including equity to be purchased by HRG through one of its wholly-owned subsidiaries.

In connection with the financing of the AAG Acquisition, Spectrum Brands is including in this Current Report on Form 8-K: (i) unaudited condensed consolidated financial statements of Armored AutoGroup Inc. as of March 31, 2015 and December 31, 2014 and for the three-month periods ended March 31, 2015 and March 31, 2014; and (ii) unaudited condensed consolidated financial statements of IDQ Holdings, Inc. as of March 31, 2015 and December 31, 2014 and for the three-month period ended March 31, 2015 and for the period January 1, 2014 through March 16, 2014 (Predecessor), and for the period March 17, 2014 through March 31, 2014 (Successor). The financial statements of Armored AutoGroup Inc. and IDQ Holdings, Inc. discussed above are attached hereto as Exhibits 99.1 and 99.2, respectively.

As reported in Armored AutoGroup Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 (the “Armored AutoGroup 10-K”), in connection with the preparation of Armored AutoGroup Inc.’s financial statements for the year ended December 31, 2014, certain significant deficiencies in internal control became evident to its management that, in the aggregate, represent a material weakness. None of the deficiencies individually represented a material weakness, and all resulting adjustments, none of which were material, have been reflected in the Armored AutoGroup Inc.’s consolidated financial statements. As reported in Armored AutoGroup Inc.’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2015 (the “Armored AutoGroup 10-Q”), the material weakness had not been fully remediated as of March 31, 2015. The Armored AutoGroup 10-K and the Armored AutoGroup 10-K are expressly not incorporated by reference into this Current Report on Form 8-K.

Spectrum Brands was aware of and reviewed these deficiencies as part of its due diligence process and determined that they were not material to Spectrum Brands. Spectrum will continue to evaluate and monitor these deficiencies as it integrates AAG into its control environment following the acquisition.

Except as expressly set forth by specific reference in another document, the information in this Current Report on Form 8-K and the exhibits hereto shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, and shall not be deemed to be incorporated by reference into any of our filings under the Securities Act of 1933 (the “Securities Act”) or the Exchange Act, whether made before or after the date hereof and regardless of any general incorporation language in such filings.
