IDT REPORTS Q2 FISCAL YEAR 2016 FINANCIAL RESULTS

Q2 FY16 Revenue of $169.5M; up 5.3% Q/Q and 23.6% Y/Y

Q2 FY16 GAAP Diluted EPS (from Continuing Operations) of $0.28

Q2 FY16 Non-GAAP Diluted EPS of $0.35

SAN JOSE, Calif., October 26, 2015 - Integrated Device Technology, Inc. (IDT^®) (NASDAQ: IDTI) today announced results for the fiscal second quarter ended September 27, 2015.

“Second quarter fiscal 2016 results were excellent. Revenue grew to $169.5 million dollars, an increase of almost 24 percent year-over-year and 5 percent sequentially, driven by a strong rebound in sales of our communications products, continued market leadership in memory interface, as well as solid contributions from our wireless charging business,” said Greg Waters, president and chief executive officer. “Combined with robust top line growth, our continued focus on execution and expense control contributed to a non-GAAP operating margin of 31 percent, and free cash flow as a percentage of revenues on a trailing twelve-month basis of 27 percent.”

“Additionally, our board recently increased our share repurchase authorization by another $300 million. This is incremental to our prior authorization and to the remaining repurchase authorization balance as of September end of $231 million. We intend to fund this incremental $300 million through debt financing, subject to market conditions, and execute this portion of our buyback on an accelerated pace. We remain well-positioned to continue delivering excellent results and increasing returns to our shareholders with a solid base of existing business, combined with exciting new product development and design-win traction,” concluded Mr. Waters.

The following highlights the Company’s financial performance on both a GAAP and supplemental non-GAAP basis. For financial statement purposes, the high speed data converter business is treated as discontinued operations for all periods presented. IDT has excluded results from the high speed data converter business from current and historical non-GAAP results. 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 from continuing operations is attached to this press release.

• Revenue from continuing operations for the fiscal second quarter of 2016 was $169.5 million, compared with $160.9 million reported last quarter, and $137.1 million reported in the same period one year ago.

• GAAP net income from continuing operations for the fiscal second quarter of 2016 was $42.4 million, or $0.28 per diluted share, versus GAAP net income from continuing operations of $38.7 million or $0.25 per diluted share last quarter, and a GAAP net income from continuing operations of $24.2 million or $0.16 per share in the same period one year ago. Fiscal second quarter 2016 GAAP results include $8.6 million in stock-based compensation expense, $1.9 million expense in severance and retention related charges, $0.8 million expense relating to amortization of intangible assets, $0.2 million expense in facility closure costs, and $0.2 million expense in related tax effects.

• Non-GAAP net income for the fiscal second quarter of 2016 was $53.9 million or $0.35 per diluted share, compared with non-GAAP net income of $48.2 million or $0.31 per diluted share last quarter, and non-GAAP net income of $31.8 million or $0.20 per diluted share reported in the same period one year ago.

• GAAP gross profit from continuing operations for the fiscal second quarter of 2016 was $106.5 million, or 62.9 percent, compared with GAAP gross profit of $99.2 million or 61.7 percent last quarter, and $81.9 million, or 59.7 percent, reported in the same period one year ago. Non-GAAP gross profit for the fiscal second quarter of 2016 was $107.5 million, or 63.4 percent, compared with non-GAAP gross profit of $100.9 million, or 62.7 percent last quarter, and $83.9 million, or 61.2 percent, reported in the same period one year ago.

Non-GAAP Reporting

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 income and other;

Provision for (benefit from) income taxes, continuing operations;

Operating income;

Net income from continuing operations;

Diluted net income per share, continuing operations; 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, stockholder expenses 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:

• Amortization of acquisition related intangibles, which include acquired intangibles such as purchased technology, patents, customer relationships, trademarks, backlog and non-compete agreements.

• Acquisition related costs such as legal, accounting and other professional or consulting fees directly related to an acquisition.

• Fair market value adjustment to acquired inventory sold.

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 from continuing operations. Restructuring-related charges (gains) primarily include:

• Severance and retention costs directly related to a restructuring action.

• Facility closure costs consist of ongoing costs associated with the exit of our leased and owned facilities.

• Gain on divestiture consists of gains recognized upon the strategic sale of business units.

• Assets impairments including accelerated depreciation of certain assets no longer in use and impairment charge related to a note receivable and subsequent recoveries.

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:

• Stock based compensation expense.

• Compensation expense (benefit) - deferred compensation, consists of gains and losses on marketable equity securities related to our deferred compensation arrangements.

• Loss (gain) on deferred compensation plan securities represents the changes in the fair value of the assets in a separate trust that is invested in corporate owned life insurance under our deferred compensation plan.

• Life insurance proceeds received, represents proceeds received under corporate owned life insurance under our deferred compensation plan.

• Tax effects of non-GAAP adjustments. Effective first quarter of fiscal 2016, the Company changed its methodology for reporting non-GAAP taxes to be based on estimated cash tax expense and reserves. The Company forecasts its annual cash tax liability and allocates the tax to each quarter in proportion to earnings for that period. This approach is designed to enhance the ability of investors to understand the impact of the Company's tax expense on its current operations, provide improved modeling accuracy, and substantially reduce fluctuations caused by GAAP to non-GAAP adjustments, which may not reflect actual cash tax expense. Non-GAAP tax amounts for periods prior to March 30, 2015 have not been adjusted to reflect the new methodology.

• Diluted weighted average shares non-GAAP adjustment, for purposes of calculating non-GAAP diluted net income per share, the GAAP diluted weighted average shares outstanding is adjusted to exclude the benefits of stock 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.
