 Additional Information and Where to Find It:This presentation does not constitute an offer to sell or the solicitation of an offer to buy any securities. The tender offer for the outstanding shares of GigPeak’s common stock described in the separate GigPeak press releases has not commenced. At the time the tender offer is commenced, IDT will file or cause to be filed a Tender Offer Statement on Schedule TO with the SEC and GigPeak will file a Solicitation/Recommendation Statement on Schedule 14D-9 with the SEC related to the tender offer. The Tender Offer Statement (including an Offer to Purchase, a related Letter of Transmittal and other tender offer documents) and the Solicitation/Recommendation Statement will contain important information that should be read carefully before any decision is made with respect to the tender offer. Those materials will be made available to GigPeak’s stockholders at no expense to them by the information agent to the tender offer, which will be announced. In addition, all of those materials (and any other documents filed with the SEC) will be available at no charge on the SEC’s website at www.sec.gov.Forward Looking Statements: This presentation contains statements regarding the anticipated consummation of the acquisition of GigPeak and the timing and benefits thereof, operating trends; expected future results and guidance; GigPeak’s and its subsidiaries’ expansion and business strategies into new markets and projects; anticipated growth opportunities; changes in business or other market conditions and product trends that are forward-looking. We undertake no obligation to update or revise the forward-looking statements, whether as a result of new information, future events or otherwise.

 Use of Non-GAAP and Adjusted EBITDA Financial Measures:These materials include references to non-GAAP net income/loss, adjusted consolidated non-GAAP net income/loss, and Adjusted EBITDA. Adjusted EBITDA is defined as net earnings before interest, taxes, other expense (income), net, depreciation and amortization, including amortization of intangibles, stock-based compensation, acquisition and strategic activities related costs and loss on equity method investment. Adjusted EBITDA differs from net earnings, as calculated in accordance with GAAP, in that it excludes the foregoing items. GigPeak believes that these non-GAAP financial measures are important indicators of the ongoing operations of its business, provide an additional metric for comparability between reporting periods, and provide an additional baseline for analyzing trends in GigPeak’s operations. In addition, Adjusted EBITDA is used in determining compliance with covenants in our term loan and revolving line agreement. GigPeak does not, nor does it suggest that investors should, consider such non-GAAP and Adjusted EBITDA financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. GigPeak believes the disclosure of the effects of these items increases the reader’s understanding of, and an enhanced level of transparency into, the underlying performance of the business and that such non-GAAP and Adjusted EBITDA financial measures provide investors with a supplemental tool to evaluate our financial results and assess our prospects for future performance.Intellectual Property:All trademarks, service marks and trade names of GigPeak, Inc. used herein are trademarks or registered trademarks of GigPeak, Inc.
