Peregrine Semiconductor Corporation (Peregrine Semiconductor) (NASDAQ: PSMI), a fabless provider of high-performance radio frequency integrated circuits (RFICs), today announced its fourth quarter and 2013 fiscal year financial results.

Fourth quarter 2013 revenue was $43.3 million, compared with $63.0 million for the same period in 2012. Revenue for fiscal year 2013 was $202.3 million, compared with $203.9 million for fiscal year 2012.

As reported under U.S. generally accepted accounting principles (GAAP), fourth quarter 2013 net loss was $6.8 million, compared with a GAAP net income of $5.6 million in the same period in 2012. Net loss for fiscal 2013 was $4.1 million, compared with a GAAP net income of $7.3 million for fiscal 2012. Diluted net loss per share was $0.21 for the fourth quarter of 2013 compared to a net income per share of $0.15 for the same period in 2012. Diluted net loss per share for fiscal year 2013 was $0.13 per share, compared net income per share to $0.15 per share for fiscal 2012.

Non-GAAP net loss for the fourth quarter of 2013 was $5.1 million, or $0.16 per diluted share based on weighted average shares outstanding of 32.7 million. This compares with non-GAAP net income of $6.9 million or $0.19 per diluted share based on weighted average shares outstanding of 36.5 million for the same period in 2012. Non-GAAP net income for fiscal year 2013 was $2.6 million, or $0.07 per diluted share based on weighted average shares outstanding of 35.7 million. This compares with non-GAAP net income of $11.7 million or $0.36 per diluted share based on weighted average shares outstanding of 32.2 million for fiscal year 2012.

Gross margin on a GAAP basis for the fourth quarter of 2013 was 36.0% of revenue, compared to 43.3% of revenue for the same period in 2012. Gross margin on a non-GAAP basis for the fourth quarter of 2013 was 36.6% of revenue, compared to 43.6% of revenue for the same period in 2012. Gross margins in the fourth quarter were impacted by a higher than normal inventory write-down of $3.1 million. Gross margin on a GAAP basis for fiscal year 2013 was 40.2% of revenue, compared to 39.1% of revenue for fiscal year 2012. Gross margin on a non-GAAP basis for fiscal year 2013 was 40.7% of revenue, compared to 39.4% of revenue for fiscal year 2012. Operating expenses increased to $22.4 million for the fourth quarter 2013 as a result of higher than expected legal expenses and restructuring charges by $1.4 million.

“We reported fourth quarter revenue in line with our prior guidance. For 2014, we see a number of challenges facing the smartphone industry. However, we believe our product development and our progress in developing an integrated RF front-end positions us well for 2015 as the industry enters a strategic transition,” commented Jim Cable, President and Chief Executive Officer. “Today, I am pleased to announce our introduction of the Ultra CMOS Global 1, the world’s first reconfigurable RF front-end system, featuring our multi-mode, multi-band power amplifier and integrated suite of switches and tuning elements. We are pleased to demonstrate that our power amplifier offers raw performance comparable with GaAs, but with all the benefits of our UltraCMOS SOI process.”

Business Outlook

For the first quarter of 2014, the company expects revenue to be in the range of $33 million to $36 million. First quarter GAAP gross margin is expected to be in the range of 36% to 38%.

Use of GAAP and Non-GAAP Financial Measures

Peregrine Semiconductor prepares its financial statements in accordance with generally accepted accounting principles for the United States (GAAP). The non-GAAP financial measures such as gross margin, net income and loss per share information for the year and three months ended December 28, 2013, and similar periods from the prior year included in this press release are different from those otherwise presented under GAAP. The non-GAAP financial measures exclude non-cash compensation expense for stock options. When evaluating the performance of our business and developing short and long-term plans, we do not consider share-based compensation charges. Although share-based compensation is necessary to attract and retain quality employees, our consideration of share-based compensation places its primary emphasis on overall shareholder dilution rather than the accounting charges associated with such grants. Because of the varying availability of valuation methodologies and subjective assumptions, we believe that the exclusion of share-based compensation allows for more accurate comparison of our financial results to previous periods. In addition, we believe it useful to investors to understand the specific impact of the application of the fair value method of accounting for share-based compensation on our operating results. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. We believe these non-GAAP financial measures provide investors with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and allow for greater transparency with respect to key metrics used by management in operating our business. However, investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. These measures may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes.

For more information on our non-GAAP financial measures and a reconciliation of such measures to the nearest GAAP measure, please see the “Condensed Consolidated Reconciliation of GAAP to Non-GAAP Results” table in this press release.
