Logitech Accelerates with Best Retail Sales Growth in Over Five Years, Up 13%

Company Raises Sales and Profit Outlook Following Better-Than-Expected Q1

NEWARK, Calif. – July 27, 2016 and LAUSANNE, Switzerland, July 28, 2016 – Logitech International (SIX: LOGN) (Nasdaq: LOGI) today raised its outlook for sales and operating income following better-than-expected financial results for the first quarter of Fiscal Year 2017.

• Q1 sales were $480 million, up 7 percent compared to Q1 of the prior year. Q1 retail sales grew 13 percent in constant currency, the highest quarterly growth in over five years.

• Q1 GAAP operating income almost doubled at $26 million compared to $14 million a year ago. Q1 GAAP earnings per share (EPS) from continuing operations were $0.13, compared to $0.08 in the same quarter a year ago.

• Q1 non-GAAP operating income was $38 million compared to $36 million a year ago, with non-GAAP EPS of $0.20, compared to $0.19 in the same quarter a year ago.

• Cash flow from operations in the quarter was $14 million, compared to a negative cash flow of $26 million a year ago.

"Our strategy is working, delivering 13 percent retail sales growth this quarter – our best in the last five years,” said Bracken Darrell, Logitech president and chief executive officer. “Our growth was better-than-expected and broad-based across regions and product categories. Virtually all our sales were in growing product categories and we grew in all our market opportunities – Creativity & Productivity, Gaming, Video Collaboration, Music, and Home – most in double digits. It’s a great start to the new year and gives us the confidence to raise our outlook."

Outlook

Logitech raised its FY 2017 outlook to 8 to 10 percent retail sales growth in constant currency, up from its previous forecast of growth in the mid-single digits. The Company also increased its non-GAAP operating income outlook for FY 2017 to between $195 million and $205 million, up from $185 million to $200 million.

Prepared Remarks Available Online

Logitech has made its prepared written remarks for the financial results teleconference available online on the Logitech corporate website at http://ir.logitech.com.

Financial Results Teleconference and Webcast

Logitech will hold a financial results teleconference to discuss the results for Q1 FY 2017 on Thurs., July 28, 2016 at 8:30 a.m. Eastern Daylight Time and 2:30 p.m. Central European Summer Time. A live webcast of the call will be available on the Logitech corporate website at http://ir.logitech.com.

Annual Report and Other Information

Logitech has posted its Invitation, Proxy Statement and Annual Report for the 2016 Annual General Meeting (AGM) on its website at http://ir.logitech.com. 

Continued Operations

Logitech separated its Lifesize division from the Company on Dec. 28, 2015. Except as otherwise noted, all of the results reported in this press release as well as comparisons between periods are focused on results from continuing operations and do not address the performance of Lifesize, which is now reported in the Company’s financial statements under discontinued operations or total Logitech including discontinued operations. For more information on the impact of the Lifesize separation on Logitech’s historical results, please refer to the Financial Reporting section of Logitech’s Financial History, available on the Logitech corporate website at http://ir.logitech.com.

Use of Non-GAAP Financial Information and Constant Currency

To facilitate comparisons to Logitech’s historical results, Logitech has included non-GAAP adjusted measures, which exclude share-based compensation expense, amortization of intangible assets, purchase accounting effect on inventory, acquisition-related costs, restructuring charges (credits), gain (loss) on equity-method investment, investigation and related expenses, non-GAAP income tax adjustment, and other items detailed under “Supplemental Financial Information” after the tables below. Logitech also presents percentage sales growth in constant currency to show performance unaffected by fluctuations in currency exchange rates. Percentage sales growth in constant currency is calculated by translating prior period sales in each local currency at the current period’s average exchange rate for that currency and comparing that to current period sales. Logitech believes this information, used together with the GAAP financial information, will help investors to evaluate its current period performance and trends in its business. With respect to the Company’s outlook for non-GAAP operating income,

most of these excluded amounts pertain to events that have not yet occurred and are not currently possible to estimate with a reasonable degree of accuracy. Therefore, no reconciliation to the GAAP amounts has been provided for Fiscal Year 2017.

__________________

(A) Preliminary valuation from the business combination

The preliminary purchase price allocation from the business combination during the current period is included in the tables. The fair value of identifiable intangible assets acquired was based on estimates and assumptions made by us at the time of acquisition. As additional information becomes available, such as finalization of the estimated fair value of the assets acquired and liabilities assumed and the fair value of contingent consideration, we may further revise our preliminary purchase price allocation during the remainder of the measurement period (which will not exceed 12 months from the acquisition date). Any such revisions or changes may be material as we finalize the fair values of the tangible and intangible assets acquired and liabilities assumed.

(B) Non-GAAP Financial Measures

To supplement our condensed consolidated financial results prepared in accordance with GAAP, we use a number of financial measures, both GAAP and non-GAAP, in analyzing and assessing our overall business performance, for making operating decisions and for forecasting and planning future periods. We consider the use of non-GAAP financial measures helpful in assessing our current financial performance, ongoing operations and prospects for the future as well as understanding financial and business trends relating to our financial condition and results of operations.

While we use non-GAAP financial measures as a tool to enhance our understanding of certain aspects of our financial performance and to provide incremental insight into the underlying factors and trends affecting both our performance and our cash-generating potential, we do not consider these measures to be a substitute for, or superior to, the information provided by GAAP financial measures. Consistent with this approach, we believe that disclosing non-GAAP financial measures to the readers of our financial statements provides useful supplemental data that, while not a substitute for GAAP financial measures, can offer insight in the review of our financial and operational performance and enables investors to more fully understand trends in our current and future performance. In assessing our business during the quarter ended June 30, 2016, we excluded items in the following general categories, each of which are described below:

Share-based compensation expenses. We believe that providing non-GAAP measures excluding share-based compensation expense, in addition to the GAAP measures, allows for a more transparent comparison of our financial results from period to period. We prepare and maintain our budgets and forecasts for future periods on a basis consistent with this non-GAAP financial measure. Further, companies use a variety of types of equity awards as well as a variety of methodologies, assumptions and estimates to determine share-based compensation expense. We believe that excluding share-based compensation expense enhances our ability and the ability of investors to understand the impact of non-cash share-based compensation on our operating results and to compare our results against the results of other companies.

Amortization of intangible assets. We incur intangible asset amortization expense, primarily in connection with our acquisitions of various businesses and technologies. The amortization of purchased intangibles varies depending on the level of acquisition activity. We exclude these various charges in budgeting, planning and forecasting future periods and we believe that providing the non-GAAP measures excluding these various non-cash charges, as well as the

GAAP measures, provides additional insight when comparing our operating expenses and financial results from period to period.

Purchase accounting effect on inventory. Business combination accounting principles require us to measure acquired inventory at fair value. The fair value of inventory reflects the acquired company’s cost of manufacturing plus a portion of the expected profit margin. The non-GAAP adjustment excludes the expected profit margin component that is recorded under business combination accounting principles associated with our acquisition of Jaybird. We believe the adjustment is useful to investors because such charges are not reflective of our ongoing operations. 

Acquisition-related costs. We incurred expenses in connection with our acquisitions which we generally would not have otherwise incurred in the periods presented as a part of our continuing operations. Acquisition related costs include all incremental expenses incurred to effect a business combination. We believe that providing the non-GAAP measures excluding these costs, as well as the GAAP measures, assists our investors because such costs are not reflective of our ongoing operating results.

Restructuring charges (credits). These expenses are associated with re-aligning our business strategies based on current economic conditions. We have undertaken several restructuring plans in recent years. In connection with our restructuring initiatives, we incurred restructuring charges related to employee terminations, facility closures and early cancellation of certain contracts. We believe that providing the non-GAAP measures excluding these charges, as well as the GAAP measures, assists our investors because such charges (credits) are not reflective of our ongoing operating results in the current period.

Gain (loss) on equity-method investment. We recognized gain (loss) related our investments in various privately-held companies, which varies depending on the operational and financial performance of the privately-held companies in which we invested. We believe that providing the non-GAAP measures excluding these charges, as well as the GAAP measures, assists our investors because such charges are not reflective of our ongoing operations.

Investigation and related expenses.  These expenses are forensic accounting, audit, consulting and legal fees related to the Audit Committee’s investigation and the formal investigation by and settlement with the Securities and Exchange Commission (SEC), together with accruals based on settlement with the SEC. We believe that providing the non-GAAP measures excluding these charges, as well as the GAAP measures, assists our investors because such charges are not reflective of our ongoing operations.

Non-GAAP income tax adjustment. Non-GAAP income tax adjustment primarily measures the income tax effect of non-GAAP adjustments excluded above and other events; the determination of which is based upon the nature of the underlying items, the mix of income and losses in jurisdictions and the relevant tax rates in which we operate. 

Each of the non-GAAP financial measures described above, and used in this press release, should not be considered in isolation from, or as a substitute for, a measure of financial performance prepared in accordance with GAAP. Further, investors are cautioned that there are inherent limitations associated with the use of each of these non-GAAP financial measures as an analytical tool. In particular, these non-GAAP financial measures are not based on a comprehensive set of accounting rules or principles and many of the adjustments to the GAAP financial measures reflect the exclusion of items that are recurring and may be reflected in the Company’s financial results for the foreseeable future. We compensate for these limitations by providing specific information in the reconciliation included in this press release regarding the GAAP amounts excluded from the non-GAAP financial measures. In addition, as noted above, we evaluate the non-GAAP financial measures together with the most directly comparable GAAP financial information.

Additional Supplemental Financial Information - Constant Currency

In addition, Logitech presents percentage sales growth in constant currency to show performance unaffected by fluctuations in currency exchange rates.  Percentage sales growth in constant currency is calculated by translating prior period sales in each local currency at the current period’s average exchange rate for that currency and comparing that to current period sales. Sales for the three months ended June 30, 2016 compared to sales for the three months ended June 30, 2015 increased 7 percent in both constant currency and U.S. Dollars. Retail sales for the three months ended June 30, 2016 compared to retail sales for the three months ended June 30, 2015 grew 13 percent in both constant currency and U.S. Dollars.
