Commenting on the Company’s Fiscal 2015 fourth quarter and full year results, Karen McGinnis, Chief Financial Officer of Mad Catz, said, “Fiscal 2015 was a challenging year for Mad Catz, as net sales for the fourth quarter and full year decreased 18% and 4% from their respective prior year periods. The net sales performance in Fiscal 2015 was driven primarily by a decrease in sales of our products, primarily audio, designed for legacy consoles and universal platforms due to the launch of the PlayStation 4 and Xbox One consoles in November 2013. Although we are experiencing strong growth in products developed for these new consoles, the decline in sales of products related to the legacy consoles has been greater than we and others in the industry anticipated. Despite the net sales decline in Fiscal 2015, our focus on profitable product placements and efforts to drive additional operational efficiencies across the business resulted in a 4% increase in gross profit and a 13% decrease in operating expenses compared to the prior year. As a result, we reduced our operating loss by $4.9 million, generated positive adjusted EBITDA of $0.3 million and ended the year with a net position of bank loan less cash of

$2.8 million. Additionally, we recognized a tax benefit of $7.2 million, which resulted in net income of $4.7 million, or $0.07 per share, for the fiscal year. Although working capital remains tight, we believe we have positioned ourselves well to capitalize on the growth opportunities in fiscal 2016.”

Summary of Key Sales Metrics

Darren Richardson, President and Chief Executive Officer of Mad Catz, commented, “Although the past couple of years have been challenging for us and the industry, we are pleased with our ability to drive operational improvements while still investing in new product development in order to capitalize on growth opportunities from the ongoing console transition as well as the increasing popularity of mobile gaming. We believe fiscal 2016 will be an exciting year for Mad Catz, particularly as we work with Harmonix to launch Rock Band 4 this holiday season. The initial response from consumers and retailers to the launch announcement and new game play has been very positive, and we expect sales of Rock Band 4 products to contribute to significant sales growth, operating leverage and cash flow in Fiscal 2016.”

Adjusted EBITDA (Loss) Reconciliation (non-GAAP)

(in thousands)

(Unaudited)

Adjusted EBITDA (loss), a non-GAAP financial measure, represents net income (loss) before interest, taxes, depreciation and amortization, stock-based compensation, the gain/loss on the change in the fair value of the related warrant liability, goodwill impairment, if any, and acquisition related items. Adjusted EBITDA is not intended to represent cash flows for the period, nor is it being presented as an alternative to operating or net income (loss) as an indicator of operating performance and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. As defined, Adjusted EBITDA is not necessarily comparable to other similarly titled captions of other companies due to potential inconsistencies in the method of calculation. We believe, however, that in addition to the performance measures found in our financial statements, Adjusted EBITDA is a useful financial performance measurement for assessing our Company’s operating performance. We use Adjusted EBITDA as a measurement of operating performance in comparing our performance on a consistent basis over prior periods, as it removes from operating results the impact of our capital structure, including the interest expense resulting from our outstanding debt, and our asset base, including depreciation and amortization of our capital and intangible assets. In addition, Adjusted EBITDA is an important measure for our lender.
