ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On January 30, 2013, DSP Group, Inc. (the “Company”) announced its financial results for the quarter and year ended December 31, 2012. A copy of the press release, dated January 30, 2013, is attached and filed herewith as Exhibit 99.1. This information, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Act of 1934, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference to such filing.

In addition to the disclosure of financial results for the quarter and year ended December 31, 2012 in accordance with generally accepted accounting principles in the United States (“GAAP”), the press release also included non-GAAP net loss and loss per share, as well as net income and diluted earnings per share, for the quarters and years ended December 31, 2012 and 2011 that excluded (a) for the quarter ended December 31, 2012, the impact of amortization of acquired intangible assets of $531,000 associated with the acquisition of the Cordless and VoIP Terminals business of NXP B.V. (the “CIPT Acquisition”) and the acquisition of BoneTone Communications Ltd. (the “BoneTone Acquisition”), and equity-based compensation expenses of $932,000; (b) for the quarter ended December 31, 2011, the impact of amortization of acquired intangible assets of $1,381,000 associated with the CIPT Acquisition, equity-based compensation expenses of $1,156,000, other income from remeasurement of our initial investment in an affiliated company of $1,343,000, and a tax benefit of $635,000 resulting from the reversal of an income tax contingency reserve that was determined to be no longer needed due to the expiration of applicable statute of limitations; (c) for the year ended December 31, 2012, the impact of amortization of acquired intangible assets of $2,310,000 associated with the CIPT Acquisition and the BoneTone Acquisition; equity-based compensation expenses of $4,985,000, restructuring expenses of $2,008,000 associated with the reorganization of our operations, and a tax benefit of $486,000 resulting from the reversal of income tax contingency reserve that was determined to be no longer needed due to the expiration of applicable statute of limitations; (d) for the year ended December 31, 2011, the impact of amortization of acquired intangible assets of $7,972,000 associated with the CIPT Acquisition; equity-based compensation expenses of $6,218,000; restructuring income of $170,000 associated with the reorganization of our operations, other income from remeasurement of our initial investment in an affilated company of $1,343,000, and a tax benefit of $635,000 resulting from the reversal of an income tax contingency reserve that was determined to be no longer needed due to the expiration of applicable statute of limitations.

The Company believes that the non-GAAP presentation in the press release is useful to investors in analyzing the results for the quarter and year ended December 31, 2012 because the exclusion of such expense may provide a more meaningful analysis of the Company’s core operating results. Further, the Company believes it is useful for investors to understand how the expenses associated with the application of FASB ASC No. 718 are reflected on its statements of income. The non-GAAP financial measures are used in addition to and in conjunction with results presented in accordance with GAAP, and are intended to provide additional insight into the Company’s operations that, when viewed with its GAAP results and the accompanying reconciliations to corresponding GAAP financial measures, offer a more complete understanding of factors and trends affecting the Company’s business. The non-GAAP presentation should not be viewed as a substitute for the Company’s reported GAAP results.
