FOR IMMEDIATE RELEASE

Cypress Reports Third-Quarter 2012 Results

SAN JOSE, Calif., October 18, 2012—Cypress Semiconductor Corp. (NASDAQ: CY) today announced its third-quarter 2012 results, which included the following highlights and remarks from its president and CEO, T.J. Rodgers.

Fellow shareholders:

Our revenue and earnings for the quarter are given below, compared with those of the prior quarter and prior year:

(In thousands, except per-share data)

We had a good quarter in tough times. Our gross and pretax margins held up, due to our continued efforts on expense control. But the world economy—and thus the semiconductor industry and our business—were below seasonal norms. The combination of historically low lead times and increasing global macroeconomic concerns, which have now impacted China, has driven our distributors and customers to lower bookings across all geographies and end markets. At the end of Q3, our book-to-bill was 0.81, down from 0.87 in Q2, with all divisions and major product lines below unity. As such, our revenue will be down next quarter, but our margins will again be reasonable. We continue to enjoy strong design win activity and market share gains, but each of those wins tends to bring in less revenue than during better times.

BUSINESS REVIEW

+ Non-GAAP¹ consolidated gross margin for Q3 was 57.1%, up slightly from the previous quarter.

+ Net inventory at the end of Q3 was $89.3 million, down 2% from Q2. This was equivalent to 93 days, down three days from the prior quarter. We expect inventory to decrease slightly in Q4. Distributor weeks of inventory, which includes in-transit inventory, increased from 6.2 weeks to 7.0 weeks.

+ Cash and investments for Q3 totaled $219 million, an increase of $8.6 million from Q2. During Q3, we repurchased 7.3 million shares for $81.6 million, or an average of $11.20 per share. From September 2011, when we announced our $400 million stock-repurchase program, through September 30, 2012, we repurchased 19.9 million shares. We have approximately $120.7 million remaining under the authorized repurchase program.

+ Long-term debt under our revolving credit facility increased by $45 million to $198 million as we finished the preparations to fund the cash payments required under the Ramtron tender offer.

Our divisional revenue and gross margins are detailed below:

Notes to Non-GAAP Financial Measures

To supplement its consolidated financial results presented in accordance with GAAP, Cypress uses non-GAAP financial measures which are adjusted from the most directly comparable GAAP financial measures to exclude certain items, as described in details below. Management believes that these non-GAAP financial measures reflect an additional and useful way of viewing aspects of Cypress’s operations that, when viewed in conjunction with Cypress’s GAAP results, provide a more comprehensive understanding of the various factors and trends affecting Cypress’s business and operations. Non-GAAP financial measures used by Cypress include:

Cypress uses each of these non-GAAP financial measures for internal managerial purposes, when providing its financial results and business outlook to the public, and to facilitate period-to-period comparisons. Management believes that these non-GAAP measures provide meaningful supplemental information regarding Cypress’s operational and financial performance of current and historical results. Management uses these non-GAAP measures for strategic and business decision making, internal budgeting, forecasting and resource allocation processes. In addition, these non-GAAP financial measures facilitate management’s internal comparisons to Cypress’s historical operating results and comparisons to competitors’ operating results.

Cypress believes that providing these non-GAAP financial measures, in addition to the GAAP financial results, are useful to investors because they allow investors to see Cypress’s results “through the eyes” of management as these non-GAAP financial measures reflect Cypress’s internal measurement processes. Management believes that these non-GAAP financial measures enable investors to better assess changes in each key element of Cypress’s operating results across different reporting periods on a consistent basis. Thus, management believes that each of these non-GAAP financial measures provides investors with another method for assessing Cypress’s operating results in a manner that is focused on the performance of its ongoing operations.

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. In addition, non-GAAP financial measures may be limited in value because they exclude certain items that may have a material impact upon Cypress’s reported financial results. Management compensates for these limitations by providing investors with reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures. 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 Financial Measures to Non-GAAP Financial Measures” tables in the accompanying press release, each of the non-GAAP financial measures excludes one or more of the following items:

Stock-based compensation expense relates primarily to the equity awards such as stock options and restricted stock. Stock-based compensation is a non-cash expense that varies in amount from period to period and is dependent on market forces that are often beyond Cypress’s control. As a result, management excludes this item from Cypress’s internal operating forecasts and models. Management believes that non-GAAP measures adjusted for stock-based compensation provide investors with a basis to measure Cypress’s core performance against the performance of other companies without the variability created by stock-based compensation as a result of the variety of equity awards used by companies and the varying methodologies and subjective assumptions used in determining such non-cash expense.

Cypress sponsors a voluntary deferred compensation plan which provides certain key employees with the option to defer the receipt of compensation in order to accumulate funds for retirement. The amounts are held in a trust and Cypress does not make contributions to the deferred compensation plan or guarantee returns on the investment. Changes in the value of the investments under the plan are excluded from the non-GAAP measures. Management believes that such non-cash item is not related to the ongoing core business and operating performance of Cypress, as the investment contributions are made by the employees themselves.

Restructuring charges primarily relate to activities engaged by management to make changes related to its infrastructure in an effort to reduce costs. Restructuring charges are excluded from non-GAAP financial measures because they are not considered core operating activities and such costs have not historically occurred in each year. Although Cypress 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 from Cypress’s non-GAAP financial measures as it enhances the ability of investors to compare Cypress’s period-over-period operating results from continuing operations.

Acquisition-related expense primarily includes: (1) amortization of intangibles, which include acquired intangibles such as purchased technology, patents and trademarks, (2) costs such as advisory, legal, accounting and other professional or consulting fees related to acquisitions, and (3) earn-out compensation expense, which include compensation resulting from the achievement of milestones established in accordance with the terms of the acquisitions. In most cases, these acquisition-related charges are not factored into management’s evaluation of potential acquisitions or Cypress’s performance after completion of acquisitions, because they are not related to Cypress’s core operating performance. Adjustments of these items provide investors with a basis to compare Cypress against the performance of other companies without the variability caused by purchase accounting.

Investment-related gains/losses primarily include: (1) impairment loss related to Cypress’s investment when it determines the decline in fair value is other-than-temporary in nature, and (2) gains/losses related to the sales of its debt and equity investments. These items are excluded from non-GAAP financial measures because they are not related to the core operating activities and operating performance of Cypress, and in most cases, such transactions have not historically occurred in every quarter. As such, management believes that it is appropriate to exclude investment-related gains/losses from Cypress’s non-GAAP financial measures, as it enhances the ability of investors to compare Cypress’s period-over-period operating results.

Cypress wrote down the book value of certain assets to their estimated fair value as management determined these assets will be donated, sold or will have no future benefit. Cypress excludes these items because the expense is not reflective of its ongoing operating results. Excluding this data allows investors to better compare Cypress’s period-over-period performance without such expense.

Cypress adjusts for the income tax effect that resulted from the non-GAAP adjustments as described above. Additionally, Cypress also excludes the impact of items that are related to historical activities in nature and not reflective of the ongoing operating results of Cypress.
