Cautions Regarding Forward Looking Statements

All statements included or incorporated by reference in this release and the related conference call for analysts and investors, other than statements or characterizations of historical fact, are forward-looking statements that are based on our current expectations, estimates and projections about our business and industry, management’s beliefs, and certain assumptions made by us, all of which are subject to change. Forward-looking statements can often be identified by words such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” “plans,” “predicts,” and similar terms, and variations or negatives of these words. Examples of forward-looking statements in this release include the Company’s financial outlook for its first quarter of fiscal year 2015, potential new markets for the Company’s products and anticipated new product and total revenue growth. Forward-looking statements are not guarantees of future performance and the Company’s actual results may differ significantly from the results discussed in the forward-looking statements. Factors and uncertainties that could affect the Company’s forward-looking statements include, among other things: identification of feasible new product initiatives, management of R&D efforts and the resulting successful development of new products and product platforms; acceptance by customers of the Company’s products; reliance on key suppliers; rapid technological change in the industries in which the Company operates; and competitive factors, including pricing pressures and the introduction by others of new products with similar or better functionality than the Company’s products. These and other risks are more fully described in the Company’s filings with the Securities and Exchange Commission, including the Company’s Annual Report on Form 10-K that was filed today, which should be read in conjunction herewith for a further discussion of important factors that could cause actual results to differ materially from those in the forward-looking statements. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Non-GAAP Measures

A non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. Non-GAAP measures are not in accordance with, nor are they a substitute for, GAAP measures. Other companies may use different non-GAAP measures and presentation of results.

We provide non-GAAP measures of non-GAAP operating expenses, non-GAAP income (loss) from operations and non-GAAP net income (loss) as a supplement to financial results based on GAAP operating expenses, GAAP income (loss) from operations and GAAP net income (loss). The Company believes that the additional non-GAAP measures are useful to investors for the purpose of financial analysis. We believe the presentation of non-GAAP measures provides investors with additional insight into underlying operating results and prospects for the future by excluding gains, losses and other charges that are considered by management to be outside of the Company’s core operating results. Management uses these measures internally to evaluate the Company’s in-period operating performance before taking into account these non-operating gains, losses and charges. In addition, the measures are used for planning and forecasting of the Company’s performance in future periods.

In deriving non-GAAP operating expenses from GAAP operating expenses, we exclude stock-based compensation charges and amortization of intangible assets. In deriving non-GAAP income (loss) from operations from GAAP income (loss) from operations, we exclude stock-based compensation charges and amortization of intangible assets. In deriving non-GAAP net income (loss) from GAAP net income (loss), we further exclude loss on extinguishment of debt and gain on the compound embedded derivative. Stock-based compensation charges, amortization of intangible assets, loss on extinguishment of debt, and gain on the compound embedded derivative represent charges that recur in amounts unrelated to the Company’s operations.

The non-GAAP financial measures we provide have certain limitations because they do not reflect all of the costs associated with the operation of our business as determined in accordance with GAAP. Non-GAAP operating expenses, non-GAAP income (loss) from operations and non-GAAP net income (loss) are in addition to, and are not a substitute for or superior to, operating expenses, income (loss) from operations and net income (loss), which are prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. A detailed reconciliation of the non-GAAP measures to the most directly comparable GAAP measure is set forth below. Investors are encouraged to review these reconciliations to appropriately incorporate the non-GAAP measures and the limitations of these measures into their analyses. For complete information on stock-based compensation, amortization of intangible assets, loss on extinguishment of debt, and the change in the fair value of our embedded derivatives, please see our Form 10-K for the year ended September 30, 2014.
