Logitech Delivers Record Q3 Sales, Raises Full-Year Profit Outlook

LAUSANNE, Switzerland - Jan. 22, 2019 and NEWARK, Calif., Jan. 21, 2019 - Logitech International (SIX: LOGN) (Nasdaq: LOGI) today announced financial results for the third quarter of Fiscal Year 2019.


•	Q3 sales were $864 million, up 6 percent in US dollars and 8 percent in constant currency, compared to Q3 of the prior year.


•	Q3 GAAP operating income reached $123 million, compared to $100 million in the same quarter a year ago. Q3 GAAP earnings per share (EPS) grew 40 percent to $0.67, compared to $0.48 in the same quarter a year ago.


•	Q3 non-GAAP operating income grew 22 percent to $143 million, compared to $117 million in the same quarter a year ago. Q3 non-GAAP EPS grew 22 percent to $0.79, compared to $0.65 in the same quarter a year ago.


•	Year-to-date cash flow from operations was $273 million, compared to $256 million in the same period a year ago.

“We delivered record sales and profits in our biggest quarter of the year,” said Bracken Darrell, Logitech president and chief executive officer. “Our innovative, diverse portfolio drove double-digit growth across Gaming, Video Collaboration, and Creativity & Productivity. On the back of this powerful performance, we are raising our profit outlook for the year.”

Outlook

Logitech raised its Fiscal Year 2019 profit outlook to between $340 million and $345 million in non-GAAP operating income, up from between $325 million and $335 million, on an annual sales outlook of 9 to 11 percent growth in constant currency.

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 Q3 FY 2019 on

Tuesday, January 22, 2019 at 8:30 a.m. Eastern Standard Time and 2:30 p.m. Central European Time. A live webcast of the call will be 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, change in fair value of contingent consideration for business acquisition, restructuring charges (credits), loss (gain) on investments in privately held companies, 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 2019.

* Note: These preliminary results for the three and nine months ended December 31, 2018 are subject to adjustments, including subsequent events that may occur through the date of filing our Quarterly Report on Form 10-Q.

(A) Preliminary valuation from the business acquisition

The preliminary fair value of assets acquired and liabilities assumed from the business acquisition in the second quarter of fiscal year 2019 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 the acquisition. As additional information becomes available, such as the finalization of the estimated fair value of the assets acquired and liabilities assumed, we may revise our preliminary or interim estimated fair value of the assets acquired and liabilities assumed during the remainder of the measurement periods (which will not exceed 12 months from the acquisition dates). Any such revisions or changes may be material, and may have a material impact over our financial condition and results of operations.

(B) Adoption of ASC Topic 606

On April 1, 2018, we adopted the new revenue standards under Accounting Standards Codification ("ASC") Topic 606. The adoption of Topic 606 did not have an impact over the total cash flows from operating, investing, or financing activities. The following tables summarize the impacts of adopting Topic 606 on our condensed consolidated statements of operations for the three and nine months ended as of December 31, 2018 and condensed consolidated balance sheets as of December 31, 2018 (in thousands):

Net sales	$	864,388	$	853,563	$	10,825	$	2,164,014	$	2,158,267	$	5,747



	As of December 31, 2018

Retained earnings	1,322,915	1,328,050	(5,135	)

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 December 31, 2018 and previous periods, 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 gross profit, 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 business acquisitions. We believe the adjustment is useful to investors because such charges are not reflective of our ongoing operations.

Acquisition-related costs and change in fair value of contingent consideration for business acquisition. We incurred expenses and credits 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. Fair value of contingent consideration is associated with our estimates of the value of earn-outs in connection with certain acquisitions. We believe that providing the non-GAAP measures excluding these costs and credits, 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.

Loss (gain) on investments in privately held companies. We recognized loss (gain) related to 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.

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
