Logitech Announces Second Quarter Financial Results for FY 2011

Company Delivers Strong Growth in Revenue and Profitability;

Increases Outlook for Full Year

FREMONT, Calif., Oct. 27, 2010 and MORGES, Switzerland, Oct. 28, 2010 — Logitech International (SIX: LOGN) (Nasdaq: LOGI) today announced financial results for the second quarter of Fiscal Year 2011.

Sales for Q2 FY 2011 were $582 million, up 17 percent from $498 million in the same quarter last year. Excluding the unfavorable impact of exchange rate changes, sales increased by 21 percent. Operating income was $51 million, an increase of 87 percent compared to $27 million in the same quarter a year ago. Net income for Q2 was $41 million ($0.23 per share) compared to $21 million ($0.11 per share) in Q2 of FY 2010. Gross margin for Q2 FY 2011 was 37.3 percent, up from 30.5 percent one year ago and the Company’s highest-ever quarterly gross margin.

Logitech’s retail sales for Q2 FY 2011 grew by 11 percent year over year, with an increase in Asia of 38 percent, an increase in the Americas of 19 percent, and a decrease in EMEA of 3 percent.  OEM sales increased by 10 percent. The LifeSize division,which was not included in the previous year’s results, contributed 6 percentage points to the Company’s Q2 FY 2011 sales growth compared to the prior year.

“We’re very pleased with our strong performance in Q2,” stated Gerald P. Quindlen, Logitech president and chief executive officer. “We delivered double-digit growth in both sales and operating income, and we continued the momentum in our LifeSize division. We also achieved the highest quarterly gross margin in our history, primarily due to favorable product mix shifts and supply chain efficiency improvements.

“As a result of our very strong gross margin performance in the first half of FY 2011, we have raised our operating income outlook for the full fiscal year. In addition, we have raised our sales outlook for the full fiscal year to include our initial estimate of sales for our line of products for Google TV. We’re very encouraged both by early indicators of enthusiasm for our Logitech Revue with Google TV and associated peripherals and the opportunity for developing another long-term growth driver for our business.”

Outlook

For Fiscal Year 2011, ending March 31, 2011, Logitech has raised its sales outlook from the previous range of $2.3 to $2.35 billion to the new range of $2.35 to $2.4 billion. The target for operating income has been raised from the previous range of $160 to $170 million to the new range of $170 to $180 million. Expected gross margin has increased to approximately 36 percent from the previous range of 34 to 35 percent. The expected tax rate continues to be approximately 16 percent.

Earnings Teleconference and Webcast

Logitech will hold an earnings teleconference on Thursday, Oct. 28, 2010 at 8:30 a.m. Eastern Daylight Time and 14:30 Central European Summer Time. A live webcast of the call, along with presentation slides, will be available on the Logitech corporate Web site at http://ir.logitech.com.

This press release contains forward-looking statements, including the statements regarding anticipated sales, operating income, gross margin and tax rate for FY 2011, and Logitech’s products for Google TV being a potential long-term growth driver. The forward-looking statements in this release involve risks and uncertainties that could cause Logitech’s actual results to differ materially from that anticipated in these forward-looking statements. Factors that could cause actual results to differ materially include: the demand of our customers and our consumers for our products and our ability to accurately forecast it; the effect of pricing, product, marketing and other initiatives by our competitors, and our reaction to them, on our sales, gross margins and profitability; if consumer reaction to and demand for Google TV and our products for it are less positive than we expect; the sales mix among our lower- and higher-margin products and our geographic sales mix; if our product introductions and marketing activities do not result in the sales and profitability growth we expect, or when we expect it; if we fail to take advantage of long-term trends in the consumer electronics and personal computers industries, including the growth of mobile computing devices such as smartphones and tablets; if there is a deterioration of business and economic conditions or significant fluctuations in currency exchange rates; competition in the video conferencing and communications industry, including from companies with significantly greater resources, sales and marketing organizations, installed base and name recognition; as well as those additional factors set forth in Logitech’s periodic filings with the Securities and Exchange Commission, including our Annual Report on Form 10-K for the fiscal year ended March 31, 2010, and our Quarterly Report on Form 10-Q for the quarter ended June 30, 2010, available at www.sec.gov.

Constant dollar sales (sales excluding impact of exchange rate changes)

We refer to our net sales excluding the impact of foreign currency exchange rates as constant dollar sales. Constant dollar sales are a non-GAAP financial measure, which is information derived from consolidated financial information but not presented in our financial statements prepared in accordance with U.S. GAAP. Our management uses these non-GAAP measures in its financial and operational decision-making, and believes these non-GAAP measures, when considered in conjunction with the corresponding GAAP measures, facilitate a better understanding of changes in net sales. Constant dollar sales are calculated by translating prior period sales in each local currency at the current period's average exchange rate for that currency.
