FOR IMMEDIATE RELEASE

SAN JOSE, Calif., July 31, 2017 - Integrated Device Technology, Inc. (IDT^®) (NASDAQ: IDTI) today announced results for the fiscal first quarter 2018, ended July 2, 2017.

“First quarter fiscal 2018 revenue increased by 12 percent sequentially, driven by our GigPeak acquisition plus broad organic growth across each of our end markets,” said Greg Waters, president and chief executive officer.  “We believe that IDT is positioned for continued revenue growth as the fiscal year progresses and expect to see acceleration in profit margin expansion and cash flows in the second half.”

The following highlights the Company’s financial performance on both a GAAP and supplemental non-GAAP basis. The Company provides supplemental information regarding its operating performance on a non-GAAP basis that excludes certain gains, losses and charges which occur relatively infrequently and which management considers to be outside our core operating results. Non-GAAP results are not in accordance with GAAP and may not be comparable to non-GAAP information provided by other companies. Non-GAAP information should be considered a supplement to, and not a substitute for, financial statements prepared in accordance with GAAP. A complete reconciliation of GAAP to non-GAAP results is attached to this press release.

To supplement its consolidated financial results presented in accordance with GAAP, IDT uses non-GAAP financial measures which are adjusted from the most directly comparable GAAP financial measures to exclude certain items, as described in detail below. Management believes that these non-GAAP financial measures reflect an additional and useful way of viewing aspects of the Company’s operations that, when viewed in conjunction with IDT’s GAAP results, provide a more comprehensive understanding of the various factors and trends affecting the Company’s business and operations. It should also be noted that IDT's non-GAAP information may be different from the non-GAAP information provided by other companies. Non-GAAP financial measures used by IDT include:

Cost of revenues;

    Gross profit;

Research and development expenses;

Selling, general and administrative expenses;

Interest and other income (expense);

Provision for (benefit from) income taxes;

Operating income;

Net income;

Diluted net income per share; and

Weighted average shares outstanding - diluted

The Company presents non-GAAP financial measures because the investor community uses non-GAAP results in its analysis and comparison of historical results and projections of the Company's future operating results. These non-GAAP results exclude acquisition related expense, restructuring and divestiture related costs (gain), share-based compensation expense, results from discontinued operations, and certain other expenses and benefits. Management uses these non-GAAP measures to manage and assess the profitability of the business. These non-GAAP results are also consistent with the way management internally analyzes IDT's financial results.

There are limitations in using non-GAAP financial measures because they are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. The presentation of non-GAAP financial information is not meant to be considered in isolation or as a substitute for the most directly comparable GAAP financial measures. The non-GAAP financial measures supplement, and should be viewed in conjunction with, GAAP financial measures. Investors should review the reconciliations of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the accompanying press release.

As presented in the “Reconciliation of GAAP to Non-GAAP” tables in the accompanying press release, each of the non-GAAP financial measures excludes one or more of the following items:

Acquisition related. Acquisition-related charges are not factored into management’s evaluation of potential acquisitions or IDT’s performance after completion of acquisitions, because they are not related to the Company’s core operating performance.

Adjustments of these items provide investors with a basis to compare IDT’s performance to other companies without the variability caused by purchase accounting. Acquisition-related expenses primarily include:

Restructuring related. Restructuring charges primarily relate to changes in IDT’s infrastructure in efforts to reduce costs and expenses (gains) associated with strategic divestitures and restructuring in force actions. Restructuring charges (gains) are excluded from non-GAAP financial measures because they are not considered core operating activities. Although IDT has engaged in various restructuring activities in the past, each has been a discrete event based on a unique set of business objectives. As such, management believes that it is appropriate to exclude restructuring charges (gains) from IDT’s non-GAAP financial measures as it enhances the ability of investors to compare the Company’s period-over-period operating results. Restructuring-related charges (gains) primarily include:

Other adjustments. These items are excluded from non-GAAP financial measures because they are not related to the core operating activities and on-going future operating performance of IDT. Excluding this data allows investors to better compare IDT’s period-over-period performance without such expense, which IDT believes may be useful to the investor community.

Other adjustments primarily include:

compensation expense attributable to future services not yet recognized in the financial statements that are treated as proceeds assumed to be used to repurchase shares under the GAAP treasury method.
