Cypress Reports Second-Quarter 2013 Results

SAN JOSE, Calif., July 18, 2013—Cypress Semiconductor Corp. (NASDAQ: CY) today announced its second-quarter 2013 results, which included the remarks below from its president and CEO, T.J. Rodgers. Highlights for the quarter included:

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)

Cypress performed well in the second quarter, posting revenue of $193.5 million—up 12.0% from the first quarter, exceeding our guidance. Our revenue growth was driven by broad strength across all business units, combined with particularly strong performance by our TrueTouch^® BU.

Our gross margins increased from 50.7% to 53.1% in the second quarter. Non-GAAP EPS was $0.14, 4.7x the first quarter, as higher revenue and gross margins combined with structural operating expense reductions generated significant revenue fall-through.

I am pleased to announce that we achieved first revenue on our new PSoC^® 4 product just 90 days after its launch—making PSoC 4 the fastest overall new product ramp in Cypress’s history. We have also shipped more than 5,000 PSoC 4 development kits, a strong leading indicator of future demand.

We ended the second quarter with a book-to-bill of 1.05 despite having our lowest lead times in five years. We thus expect our revenue to grow again sequentially in the third quarter and with continued strong earnings leverage.

Finally, I am proud to announce that our products won four awards last quarter. Embedded Computing Design magazine named PSoC 4 an “Editor’s Choice Product” in May, and our fourth-generation touchscreen chip, Gen4, won in June. PSoC 4 also won the 19^th annual “Product of the Year” award given by Japan’s Semiconductor Industry News. Finally, Cypress subsidiary AgigA Tech received a gold medal for its nonvolatile memory systems in the renowned Edison Awards.

BUSINESS REVIEW

+ Our non-GAAP consolidated gross margin for the second quarter was 53.1%, up 2.4 percentage points from the previous quarter, due mainly to improvement in factory utilization and product and customer mix. Our second-quarter GAAP consolidated gross margin was 47.3%.

+ Net inventory at the end of the second quarter was $98.6 million, down $10.6 million, or 9.7% from the first quarter, driven down by an active corporate initiative. This figure includes $27.3 million of inventory acquired from Ramtron.

+ Cash and investments for the second quarter totaled $102.0 million, flat from the prior quarter. During the quarter we used $16.1 million to pay our regular quarterly dividend and $9.7 million to pay down debt.

SECOND-QUARTER 2013 HIGHLIGHTS

+ Cypress introduced the first two product families based on its PSoC 4 programmable system-on-chip architecture: the PSoC 4100 and PSoC 4200 families. The new families provide an entire mixed-signal embedded system chip with a 32-bit ARM^® Cortex™-M0 core for prices as low as $1. The PSoC 4100 family, the lowest-cost ARM-based PSoC, brings PSoC flexibility and integration to cost-sensitive, high-volume applications. The PSoC 4200 family features a faster processor, a 36-button CapSense block, four programmable logic blocks to create custom digital functions, programmable analog blocks for variable-gain amplifiers and configurable filters, programmable serial interfaces, programmable input/output pins, and multiple programmable timers, counters and waveform generators—all on a chip one-tenth the size of an average little fingernail.

+ Cypress’s new PSoC 3 MFi Digital Audio Development Kit helps the designers of MFi (Made for iPod | iPhone | iPad) mobile devices and accessories to accelerate designs that use Apple’s new, all-digital Lightning connector. PSoC-based digital audio solutions ensure bit-perfect audio streaming with no added or dropped audio samples. PSoC is the de facto standard for digital audio in the music industry, providing Cypress with a strong position in the fast-growing, $7 billion MFi accessory market.

+ Cypress released four new PSoC Components™ for PSoC Creator™ 2.2, the Integrated Design Environment (IDE) that supports PSoC products. PSoC Components are production-ready “virtual chips” that replace and integrate multiple competitor chips onto a single PSoC to create highly customized single-chip system solutions for a broad array of applications, from the Tesla automotive dashboard to smart residential power meters to cell phone touchscreens.

+ Customer demand for Cypress’s new TrueTouch Gen5 touchscreen controllers has exceeded expectations, in part due to its industry-leading noise immunity. Noise from cell phone chargers can render mobile phones inoperable during charging. Gen5 offers a 3x improvement in noise immunity versus Gen4, which itself offered best-in-class performance.

+ Cypress introduced new features in its TrueTouch Gen4 capacitive touchscreen controller family, including the industry’s best tracking of gloved fingers. The Gen4 solution automatically switches into glove-mode based on the touch of a gloved finger, as compared with competitive solutions that require users to remove their gloves and change their smartphones’ settings in order to enable gloved touches. The family also delivers passive stylus support to capture handwriting and signatures accurately, and proximity detection that can eliminate false touches such as those caused by a user’s face when making a call on a mobile phone.

+ Cypress expanded its market-leading USB product portfolio with a USB-Serial bridge controller family. The family is the industry’s first to provide CapSense^® capacitive touch-sensing functionality along with two serial channels with configurable UART/SPI/I²C communication capability. The family is also the first to integrate efficient battery-charge detection compliant with Version 1.2 of the USB Implementers Forum (USB-IF) battery charging specification.

+ Cypress qualified a Bluetooth^® Low Energy radio on its S8™ 130-nanometer flash-based SONOS process technology to combine with its PSoC, CapSense and TrueTouch technologies, allowing the company to move forward with single-chip solutions for emerging Bluetooth Smart applications such as PC peripherals, sporting goods and fitness devices, healthcare equipment and smart remote controls.

+ Cypress announced that its Board of Directors approved a quarterly cash dividend of $0.11 per share, payable to holders of record of the company’s common stock as of the close of business on June 27, 2013. This dividend will be paid on July 18, 2013.

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, (3) severance expense incurred in connection with acquisition-related headcount reduction efforts, and (4) 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.

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, which can include completion of examinations by our U.S. or foreign taxing authorities, lapse of statutes of limitations and the resolution of agreements with domestic and various foreign tax authorities. This also includes foreign currency gain or loss effects on the activities mentioned above.
