PERICOM SEMICONDUCTOR REPORTS

FISCAL THIRD QUARTER 2013 FINANCIAL RESULTS

§ Q3 revenues were $30.4 million, in line with prior quarter, despite continuing global softness in the PC industry

§ Q3 gross margin increased 100 bps year-over-year, consistent with our focus on higher margin sectors

§ Continued strong balance sheet with quarter-end cash and investments at $5.15 per share

San Jose, Calif. – April 30, 2013 - Pericom Semiconductor Corporation (NASDAQ: PSEM), a worldwide supplier of high performance connectivity and timing solutions, today announced results for its fiscal 2013 third quarter ended March 30, 2013.

Net revenues for the third quarter were $30.4 million, a decrease of $67,000 or 0.2% from revenues reported in the second quarter, and a decrease of 9.0% from the $33.4 million reported in the comparable period last year.

GAAP gross margin was 35.7% in the third quarter, a decrease from 36.8% last quarter and an increase from 34.7% in the comparable period last year. On a non-GAAP basis, gross margin was 37.5% in the third quarter, which reflects exclusion of share-based compensation, amortization of intangible assets and amortization of fair value adjustments on acquired fixed assets. The comparable non-GAAP gross margins were 38.5% last quarter and 36.2% in the comparable period last year. The improvement in gross margin from the prior year primarily reflects favorable product mix from our focus on higher margin opportunities in networking and telecom, server, storage, and embedded end-market segments. The sequential decline in gross margin primarily reflects increased underutilization expenses in the current quarter.

GAAP net loss for the third quarter was $0.7 million, or $0.03 per diluted share, compared with net loss of $5.3 million, or $0.23 per diluted share in the second quarter, and net loss of $0.3 million, or $0.01 per diluted share in the comparable period last year. GAAP net income for all periods included share-based compensation, amortization of intangible assets, and amortization of fair value adjustments, and the second and third quarter also included tax provisions totaling $5.4 million resulting from intercompany transactions completed in implementing an operating structure to more efficiently align transaction flows with our geographic business operations. Excluding these items, non-GAAP net income for the third quarter was $1.0 million, or $0.04 per diluted share, compared with non-GAAP net income of $0.9 million or $0.04 per diluted share in the second quarter, and non-GAAP net income of $1.7 million, or $0.07 per diluted share in the comparable period last year.

The balance sheet remained very strong with cash and cash equivalents and investments in marketable securities of $119 million or $5.15 per diluted share at the end of the third quarter. Inventories decreased $2.3 million or 14% on a sequential basis to $13.9 million, which represents 67 days of supply based on non-GAAP cost of revenues. Trade accounts receivable increased by $0.9 million sequentially to $20.7 million, which represents DSO of 62 days. At quarter-end, working capital was $115 million and the current ratio was 6.9.

“We are pleased to deliver revenue and gross margin at the high end of our previous guidance. While business from the computing segment remained soft, we were able to offset the decline in computing revenue with increased revenue from embedded market segments and delivered sequentially flat revenue,” said Alex Hui, President and CEO of Pericom. “We will continue to focus on our long-term growth strategy of expanding our customer base in networking, cloud computing and embedded applications with our high performance serial connectivity and timing solutions.”

New Products

In the third quarter of fiscal 2013, Pericom introduced a total of 17 new products in our Connectivity, Timing, and Signal Integrity product areas enabling networking, cloud computing, embedded and smart mobile applications.

NEWS RELEASE April 30, 2013

Non-GAAP Financial Information

In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (GAAP), this announcement of operating results contains non-GAAP financial measures that exclude the income statement effects of share-based compensation, amortization of intangible assets, fair value adjustments on acquired fixed assets, a tax provision on intercompany transactions and the effects of excluding share-based compensation upon the number of diluted shares used in calculating non-GAAP earnings per share.

We have excluded share-based compensation expense in calculating these non-GAAP financial measures.  These expenses are non-cash in nature and rely on valuations of the future market price of our common stock that is difficult to predict and is affected by market factors that are largely not within the control of management. We have excluded amortization of intangible assets, amortization of fair value adjustments on acquired fixed assets, tax on an intercompany transaction and the corresponding tax effects of these adjustments because we do not consider them to be related to our core operating performance. We also use non-GAAP data in calculating certain metrics such as non-GAAP cost of revenues in computing inventory days of supply.

We use the non-GAAP financial measures that exclude these items to make strategic decisions, forecast future results and evaluate the Company’s current operating performance. We believe that the presentation of non-GAAP financial measures that exclude these items is useful to investors because we do not consider these charges either part of the day-to-day business or reflective of the core operational activities of the Company that are within the control of management or that are used to evaluate the Company’s operating performance.

The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations to those financial statements should be carefully evaluated. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. The Company has provided reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures.

Safe Harbor Statement

This press release contains forward-looking statements as defined under The Securities Litigation Reform Act of 1995. Forward-looking statements in this release include the statements under the captions “Fiscal Q4 2013 Outlook”, which regard the anticipated revenues, gross margin, operating expenses, other income, and effective tax rate in the fourth fiscal quarter of 2013, and statements from our CEO regarding challenging times for the industry and other future expectations. The Company’s actual results could differ materially from what is set forth in such forward-looking statements due to a variety of risk factors, including softness in demand for our products, price erosion for certain of our products, unexpected difficulties in developing new products, customer decisions to reduce inventory, economic or financial difficulties experienced by our customers, or technological and market changes. All forward-looking statements included in this document are made as of the date hereof, based on information available to the Company as of the date hereof, and Pericom assumes no obligation to update any forward-looking statements. Parties receiving this release are encouraged to review our annual report on Form 10-K for the year ended June 30, 2012, our quarterly report on Form 10-Q for the quarter ended December 29, 2012, and in particular, the risk factors section contained in those reports.
