Logitech Delivers Record Q3 Results

Strong growth in audio, video, remotes propels quarterly revenue past half billion dollar

mark for the first time in the Company’s history

FREMONT, Calif., Jan. 18, 2006 and ROMANEL-SUR-MORGES, Switzerland, Jan. 19, 2006 — Logitech International (SWX: LOGN) (Nasdaq: LOGI) today posted record financial results for the third quarter of FY 2006, its twenty-ninth consecutive quarter of double-digit sales growth.

For Logitech’s third quarter of FY 2006, ended December 31, 2005, sales were $574 million, up 19 percent from $484 million in the same quarter last year. Operating income was $80.7 million, up 10 percent from $73.6 million last year. Net income for the quarter was $71.3 million ($.71 per share), up 11 percent from $64.2 million ($.66 per share) in the prior year. Gross margin was 32.3 percent, down from 34.8 percent in Q3 FY 2005, and up sequentially from 31.4 percent in Q2 FY 2006.

Logitech’s retail sales in the third quarter were up 19 percent over the prior year, driven by strong demand for audio, video and remote-control products. Retail sales growth was 15 percent in EMEA, 26 percent in the Americas and 20 percent in Asia Pacific. The Company’s OEM sales were up 15 percent over last year, primarily due to sales of mice.

“Our strong sales growth during the important holiday-buying season confirms that Logitech is successfully executing our strategy to ride the wave of key consumer trends – the popularity of digital music, the pervasiveness of broadband connectivity, and the evolving role of the PC as an entertainment and communication platform,” said Guerrino De Luca, Logitech president and chief executive officer. “Our audio and video products continue to be key growth drivers. And the Harmony remotes product line has established itself as an additional driver, with significant future opportunities.

“Even with audio representing a higher proportion of the retail product mix compared to the previous two quarters, we still achieved a sequential increase in gross margin of nearly 100 basis points, due in part to continued improvements in the audio category.”

Highlights for Logitech’s Q3 FY 2006

Outlook

For the current fiscal year, ending March 31, 2006, the Company targets sales growth of at least 20 percent for the full fiscal year, compared to its previous target of 18-20 percent. The Company continues to expect operating income growth for the full fiscal year to exceed 15 percent and gross margin to be at the low end of the company’s long-term target range of 32 to 34 percent.

The company also provided preliminary financial targets for Fiscal Year 2007, ending March 31, 2007, of 15 percent year-over-year growth in sales and operating income, excluding the impact of new accounting for expensing stock-related compensation.

This press release contains forward-looking statements regarding expected sales, operating income and gross margin for Fiscal Year 2006, long-term gross margin target range and sales and operating income growth for Fiscal Year 2007. These forward-looking statements involve risks and uncertainties that could cause Logitech’s actual performance to differ materially from that anticipated in these

forward-looking statements. Factors that could cause actual results to differ materially include our ability to introduce successful products in a timely manner, the effect of pricing, product, marketing and other initiatives by our competitors and our reaction to them on our sales, gross margins and profitability, our ability to match production to demand and to coordinate the worldwide manufacturing and distribution of our products in a timely and cost-effective manner, the sales mix between our lower- and higher-margin products, consumer demand for our products and our ability to accurately forecast it, as well as those additional factors set forth in our periodic filings with the Securities and Exchange Commission, including our annual report on Form 20-F for the fiscal year ended March 31, 2005, and our quarterly reports on Form 6-K, available at www.sec.gov . Logitech does not undertake to update any forward-looking statements.

The operating income target for Fiscal Year 2007 excluding stock-related compensation is a non-GAAP financial measure under new accounting rules that require the expensing of stock-related compensation effective for Logitech beginning with its next fiscal year, starting April 1, 2006. Under these rules, the Company is required to determine the appropriate fair value model to be used to value share-based payments, the amortization method for compensation cost and the transition method to be used at the date of adoption. Logitech is in the process of making these determinations and as a result at this time management is unable to provide a non-GAAP to GAAP reconciliation of its Fiscal Year 2007 operating income target.
