Cypress Reports First-Quarter 2012 Results

SAN JOSE, Calif., April 19, 2012 —Cypress Semiconductor Corp. (NASDAQ: CY) today announced the results of the first quarter of 2012, which included the following highlights and remarks from its CEO, T.J. Rodgers.

Fellow shareholders:

Our revenue and earnings (loss) for the quarter are given below, compared with the prior-quarter and prior-year results:

Our first-quarter revenue decreased 24% sequentially and 21% year-on-year, consistent with our revised guidance. The sequential revenue decrease was mainly due to a one-quarter hole in our TrueTouch^® revenue stream which, in turn, was due to the late introduction of our newest Gen4 product, which has been in the market gathering design wins since the last week of December 2011. Our backlog has been growing rapidly since then, and we expect that backlog to deliver significant revenue growth in Q2 and beyond.

The revenue of our DCD division increased 6% versus that of Q4 2011. All other divisions decreased sequentially as expected. Our distributors’ inventory decreased by 16% sequentially, marking the third consecutive quarterly decrease. Inventories in the supply chain remain very low, and we continue to believe our shipments have been less than the true end-demand of our customers.

After four consecutive quarters of a declining book-to-bill ratio, we have finally seen a significant increase across all major product lines and in all geographies. Our book-to-bill ratio for Q1 was 1.33, well above the normal level in the traditionally slow first quarter. We thus expect Q2 revenue to increase significantly, and earnings to grow at a faster rate than sales, due to our continued restraint of operating expenses.

Our outlook is positive. We have the strongest product portfolio in our history, with numerous new revenue drivers across multiple product lines. We have not only a growing backlog, but a strong design pipeline, which combined with strong operating leverage from increasing revenue will allow us to drive earnings and cash flow.

BUSINESS REVIEW

+ Our non-GAAP¹ consolidated gross margin for the first quarter was 55.7% (57.3% core semiconductor), down only 0.4% from the previous quarter, despite the revenue decline and down-market pricing pressures.

+ Our net inventory at the end of the first quarter was up slightly (6.1%) versus that of Q4 2011 as we built WIP to support the increased backlog. Our distributor inventory, which is much larger than our net inventory, decreased 16% sequentially, the third consecutive quarterly decrease.

+ Cash and equivalents for the first quarter totaled $108.7 million, a decrease of $57.6 million from the prior quarter due to stock repurchases. During the quarter, we bought back 6.1 million shares of common stock (3.9% of total outstanding shares) for $98.0 million. Since we announced our new $400-million stock repurchase program in September 2011, we have repurchased 11.1 million shares through April 1, 2012 and have approximately $222.2 million left for additional repurchases.

+ Operating Segments—We have realigned our operating segments as outlined below.

Beginning with the three months ended April 1, 2012, we have reported our financial results under the four business segments described above. Furthermore, all historical financial information in this press release, as well as the financial information on our website, has been updated to reflect those changes.

Our revenue and gross margins under the new business segment structure are detailed below:

FIRST-QUARTER 2012 HIGHLIGHTS

+ Cypress announced that its TrueTouch controllers power the new “floating touch™” navigation feature on the new Xperia™ sola smartphone from Sony Mobile Communications. The sola is the world’s first smartphone with “hover” technology, which anticipates the touch of a finger before it makes contact with the screen. Hovering enables new applications and navigation options, such as 3D interfaces, magnification of an area of the screen as a finger approaches, and the ability to use the touch interface with gloves – ideal for users in cold climates.

+ Cypress unveiled the industry’s first single-layer touchscreen sensor with multitouch capability. The breakthrough SLIM^® (Single-Layer Independent Multitouch) sensor delivers high-performance touchscreen accuracy and responsiveness with a true single-layer sensor panel, significantly reducing the cost of the most expensive component of the touchscreen. Today’s touchscreens use two separate layers of conductors to form the rows and columns of the sensor. By creating a TrueTouch sensing solution with a unique pattern on a single-layer conductor, Cypress allows its customers to save more on the sensor cost than the entire cost of our TrueTouch chip. Thus, the new SLIM sensor will bring capacitive touchscreen technology and multifinger gesture capabilities beyond expensive “smartphones” into the higher-volume market for “feature phones.”

+ Cypress announced that its single-chip Gen4 TrueTouch controllers have been certified for the new Windows^® 8 operating system from Microsoft^® Corp.

+ Cypress introduced the TMA140 family of TrueTouch controllers for low-cost mobile phones. The new family offers high-performance touchscreen control with multifinger support and best-in-class signal-to-noise ratio (SNR) for screens as large as 5 inches. It supports Cypress’s patent-pending Charger Armor™ feature, which prevents false touches due to excessive charger noise and is compatible with Cypress’s new low-cost SLIM sensors.

+ Cypress released two new “components” in its PSoC Creator™ 2.0 design environment for the PSoC 3 and PSoC 5 programmable system-on-chip families. Components are virtual chips with programmable analog and programmable digital functions that accelerate design and enable customers to create feature-rich end products in software, without the need to integrate the hardware of multiple companies. One component released in the recent component packs lets designers customize digital filters with performance superior to that of any conventional MCU solution.

+ Cypress’s USB 3.0 controller, dubbed EZ-USB^® FX3™, has been chosen as the standard hardware for the SuperSpeed Microsoft reference USB Test Tool (SuperMUTT). SuperMUTT can be used with virtually any USB 3.0-enabled host driver to test USB compliance and compatibility with Microsoft’s upcoming Windows 8 operating system. The FX3 solution was selected because its programmability allows for unprecedented flexibility and “future-proofing.” USB 3.0 chips are 10 times faster than the USB 2.0 chips they replace.

+ Cypress introduced its General Programmable Interface II (GPIF™ II) Designer Software for its FX3 USB 3.0 controllers. The software gives designers a powerful, easy-to-use graphical interface to configure FX3 to communicate with any microcontroller, ASIC, FPGA, image sensor, or similar devices that need USB connectivity. This is part of the “programmability” that led to the Microsoft reference design win outlined above. The software shortens development time and accelerates time to market for USB 3.0 applications.

+ Cypress and Tokyo Electron Device (TED) have jointly developed a USB 3.0 device interface card for FPGA designs. The TB-FMCL-USB30, available from TED, uses Cypress’s FX3 controller to implement USB 3.0. The card lets users easily incorporate a USB 3.0 interface into Xilinx FPGA designs.

+ Cypress appointed Badri Kothandaraman Executive Vice President of its Data Communications Division (DCD) in addition to his current position as the Executive Director of Cypress Semiconductor India. Kothandaraman, who has been with Cypress for more than 16 years, will manage Cypress’s DCD (USB) business from our Bangalore subsidiary.

+ Cypress’s Board of Directors approved a quarterly dividend of $0.11 per share, payable to holders of record of the company’s common stock at the close of business on March 29, 2012. The Q1 dividend, which will be paid on April 19, 2012, represents a 22% increase from the $0.09 Q4 dividend.

+ Cypress filed a joint motion to release global telecommunications provider Ericsson from Cypress’s complaint to the United States International Trade Commission (ITC) regarding the alleged infringement of Cypress’s SRAM patents by GSI Technology Inc. Cypress seeks an exclusion order from the ITC that will prevent the importation of all infringing GSI SRAMs. Ericsson is the fifth customer that has been released from the case, in support of Cypress’s aggressive defense of its intellectual property rights.

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.

Cypress recognizes gains resulting from the exiting of certain non-strategic businesses that no longer align with Cypress’s long-term operating plan. Cypress excludes these items from its non-GAAP financial measures primarily because it is not reflective of the ongoing operating performance of Cypress’s business and can distort the period-over-period comparison.

Cypress committed to donate an unused building to a charitable entity. 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.

Acquisition-related expense primarily includes: (1) amortization of intangibles, which include acquired intangibles such as purchased technology, patents and trademarks, and (2) 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.
