The Company and Summary of Significant Accounting Policies and Estimates The Company and Summary of Significant Accounting Policies and Estimates
The Company
Logitech International S.A., together with its consolidated subsidiaries ("Logitech" or the "Company"), designs software-enabled hardware solutions that help businesses thrive and bring people together when working, creating, and gaming. As the point of connection between people and the digital world, the Company's mission is to extend human potential in work and play, in a way that is good for people and the planet.
The Company sells its products to a broad range of international customers, including direct sales to retailers, e-tailers, businesses large and small and end consumers through the Company's e-commerce platform, and indirect sales to end customers through distributors.
Logitech was founded in Switzerland in 1981 and Logitech International S.A. has been the parent holding company of Logitech since 1988. Logitech International S.A. is a Swiss holding company with its registered office in Hautemorges, Switzerland, and headquarters in Lausanne, Switzerland, which conducts its business through subsidiaries in the Americas, Europe, Middle East and Africa ("EMEA") and Asia Pacific. Shares of Logitech International S.A. are listed on both the SIX Swiss Exchange under the trading symbol LOGN and the Nasdaq Global Select Market under the trading symbol LOGI.
Basis of Presentation
The condensed consolidated financial statements include the accounts of Logitech and its subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and therefore do not include all the information required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2025, included in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on May 23, 2025.
In the opinion of management, these condensed consolidated financial statements include all adjustments, consisting of only normal and recurring adjustments, necessary and in all material aspects, for a fair statement of the results of operations, comprehensive income, financial position, cash flows and changes in shareholders' equity for the periods presented. Operating results for the three and six months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2026, or any future periods.
Changes in Significant Accounting Policies
There have been no material changes in the Company’s significant accounting policies during the three and six months ended September 30, 2025 compared with the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended March 31, 2025.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill and intangible assets acquired from business acquisitions, pension obligations, accruals for customer incentives, cooperative marketing, and pricing programs and related breakage when appropriate, inventory valuation, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates.
 
Risks and Uncertainties
Impacts of Macroeconomic and Geopolitical Conditions on the Company's Business
In 2025, the United States introduced trade policy actions that have increased import tariffs across a wide range of countries at various rates, with certain exemptions. These tariff policies in the U.S. and responsive policies enacted in other countries are evolving. The incremental tariffs have had and may continue to have an adverse impact on the Company's results of operations. In addition, the Company's business has continued to be impacted by ongoing macroeconomic and geopolitical conditions. These conditions include inflation, interest rate and foreign currency fluctuations, uncertainty in consumer and enterprise demand, low economic growth in certain regions, changes in fiscal policies and geopolitical conflicts.
The global and regional economic and political conditions, as well as changes in trade policies, have caused and may continue to cause volatility in demand for the Company's products as well as the cost of tariffs, materials and logistics, and transportation delays, and as a result have impacted and may continue to impact the pricing of the Company's products, product availability and the Company's results of operations.

Share-based compensation costs capitalized as part of inventory were $2.0 million and $1.8 million for the three months ended September 30, 2025 and 2024, respectively, and $4.8 million and $4.3 million for the six months ended September 30, 2025 and 2024, respectively.

Defined Benefit Plans
 
Certain subsidiaries of the Company sponsor defined benefit pension plans or non-retirement post-employment benefits covering substantially all of their employees. Benefits are provided based on employees’ years of service and earnings, or in accordance with applicable employee benefit regulations. The Company’s practice is to fund amounts sufficient to meet the requirements set forth in the applicable employee benefit and tax regulations. The costs of $1.8 million recorded for each of the three months ended September 30, 2025 and 2024, and $3.5 million recorded for each of the six months ended September 30, 2025 and 2024, were primarily related to service costs.

Income Taxes Income Taxes
 
The Company is incorporated in Switzerland but operates in various countries with differing tax laws and rates. Further, a portion of the Company’s income before taxes and the provision for income taxes is generated outside of Switzerland.

The income tax provision for the three and six months ended September 30, 2025 was $32.4 million and $60.9 million based on an effective income tax rate of 15.9% and 16.1% of pre-tax income, respectively. The income tax provision for the same periods ended September 30, 2024 was $30.6 million and $56.1 million based on an effective income tax rate of 17.4% and 16.3% of pre-tax income, respectively. The change in the effective income tax rate for the three and six months ended September 30, 2025, compared with the same periods ended September 30, 2024, was primarily due to the change in the mix of income and losses in the various tax jurisdictions in which the Company operates and less tax incentives for foreign derived intangible income and R&D as compared to prior period, offset by return to provision adjustments.

The change in the effective income tax rate for the three and six months ended September 30, 2025, compared with the same periods ended September 30, 2024, was primarily due to the change in the mix of income and losses in the various tax jurisdictions in which the Company operates and less tax incentives for foreign derived intangible income and R&D as compared to prior period, offset with a change in uncertain tax positions.

On July 4, 2025, the One Big Beautiful Bill Act (the "OBBBA") was enacted into law in the United States and will be generally effective for the Company beginning in fiscal year 2027. The OBBBA includes numerous provisions that affect corporate taxation, impacting areas such as R&D expensing, bonus depreciation, and international tax provisions. The Company has reviewed the provisions of the OBBBA to determine the potential impact on the Company's financial statements. Based on this review, and considering the Company's current tax position and operations, at this time the Company does not expect the OBBBA to have a material impact on its income taxes, including current and deferred tax balances and the effective tax rate. However, the Company is still in the process of evaluating the full impact of the OBBBA and any material changes to the Company's assessment will be disclosed in future filings as required.

For the three months ended September 30, 2025, the Company assessed its exposure to the OECD Pillar Two global minimum tax rules. The Company has determined that, for the fiscal year 2026, most jurisdictions in which it operates should qualify for the transitional Country-by-Country Reporting ("CbCR") safe harbor, as outlined in the OECD Administrative Guidance and enacted domestic legislation. The Company's CbCR has been prepared in accordance with the requirements for a Qualified CbCR, using qualified financial statements. Based on this data, most jurisdictions continue to meet safe harbor qualifications at 16% tax rates, and therefore, the Company is only required to perform a detailed Pillar Two top-up tax calculation for limited jurisdictions. The estimated top up tax for fiscal year 2026 is not material and has been included in the calculation of the Company's annual effective tax rate. The OECD and participating countries continue to issue underlying rules and administrative guidance related to Pillar Two, and the Company continues to monitor the relevant developments.

Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
 
Fair Value Measurements
 
The Company considers fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Company utilizes the following three-level fair value hierarchy to establish the priorities of the inputs used to measure fair value:
 
•Level 1 — Quoted prices in active markets for identical assets or liabilities.
 
•Level 2 — Observable inputs other than quoted market prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
 
•Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
The following table presents the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis, excluding assets related to the Company’s defined benefit pension plans, classified by the level within the fair value hierarchy (in thousands):

Investments for Deferred Compensation Plan

The marketable securities for the Company's deferred compensation plan were recorded at a fair value of $33.2 million and $29.0 million, as of September 30, 2025 and March 31, 2025, respectively, based on quoted market prices. Quoted market prices are observable inputs that are classified as Level 1 within the fair value hierarchy. Unrealized gains (losses) related to marketable securities for the three and six months ended September 30, 2025 and 2024 were not material and are included in other income (expense), net and corresponding changes in the deferred compensation liability were included in operating expenses and cost of goods sold, in the Company's condensed consolidated statements of operations.

Equity Method Investments

The Company has certain non-marketable investments included in other assets that are accounted for as equity method investments, with a carrying value of $18.8 million and $18.4 million as of September 30, 2025 and March 31, 2025, respectively. Income (loss) related to equity method investments for the three and six months ended September 30, 2025 and 2024 were not material and are included in other income (expense), net in the Company's condensed consolidated statements of operations. There was no impairment of equity method investments during the three and six months ended September 30, 2025 and 2024.

Assets Measured at Fair Value on a Nonrecurring Basis

Financial Assets 

The Company has certain equity investments without readily determinable fair values due to the absence of quoted market prices, the inherent lack of liquidity, and the fact that inputs used to measure fair value are unobservable and require management's judgment. When certain events or circumstances indicate that impairment may exist, the Company revalues the investments using various assumptions, including the financial metrics and ratios of comparable public companies. The carrying value is also adjusted for observable price changes with the same or similar security from the same issuer. The amount of these equity investments without readily determinable fair value included in other assets was $8.8 million as of September 30, 2025 and March 31, 2025. There was no impairment of these equity investments during the three and six months ended September 30, 2025. The impairment charges related to the equity investments were not material during the three and six months ended September 30, 2024.
Non-Financial Assets
Goodwill, intangible assets, and property, plant and equipment, are not required to be measured at fair value on a recurring basis. However, if the Company is required to evaluate these non-financial assets for impairment, whether due to certain triggering events or because of the required annual impairment test, and a resulting impairment is recorded to reduce the carrying value to the fair value, the non-financial assets are measured at fair value during such period. There was no impairment of non-financial assets during the three and six months ended September 30, 2025 and 2024.

Under certain agreements with the respective counterparties to the Company’s derivative contracts, subject to applicable requirements, the Company is allowed to net settle transactions of the same type with a single net amount payable by one party to the other. However, the Company presents its derivative assets and derivative liabilities on a gross basis in other current assets and accrued and other current liabilities, respectively, on the condensed consolidated balance sheets as of September 30, 2025 and March 31, 2025. See Note 6 for the fair values of the Company’s derivative instruments as of September 30, 2025 and March 31, 2025.

Cash Flow Hedges

The Company enters into cash flow hedge contracts to protect against exchange rate exposure of forecasted inventory purchases. Previously, the hedge contracts covered inventory purchases within four months. Beginning in the first quarter of fiscal year 2026, they cover inventory purchases up to twelve months, with reduced coverage beyond four months. Gains and losses in the fair value of the effective portion of the hedges are deferred as a component of accumulated other comprehensive income (loss) until the hedged inventory purchases are sold, at which time the gains or losses are reclassified to cost of goods sold. Cash flows from such hedges are classified as operating activities in the condensed consolidated statements of cash flows. Hedging relationships are discontinued when the hedging contract is no longer eligible for hedge accounting, or is sold, terminated or exercised, or when the Company removes hedge designation for the contract. Gains and losses in the fair value of the effective portion of the discontinued hedges continue to be reported in accumulated other comprehensive income (loss) until the hedged inventory purchases are sold, unless it is probable that the forecasted inventory purchases will not occur by the end of the originally specified time period or within an additional two-month period of time thereafter.

The notional amounts of foreign currency exchange forward contracts outstanding related to forecasted inventory purchases were $301.0 million and $74.6 million as of September 30, 2025 and March 31, 2025, respectively. The Company had $6.8 million of net loss related to its cash flow hedges included in accumulated other comprehensive loss as of September 30, 2025, which will be reclassified into earnings within the next twelve months.
The following table presents the amounts of gain (loss) on the Company’s derivative instruments designated as hedging instruments for the three and six months ended September 30, 2025 and 2024 and their locations on its condensed consolidated statements of operations and condensed consolidated statements of comprehensive income (in thousands):

Other Derivatives
 
The Company also enters into foreign currency exchange forward and swap contracts to reduce the short-term effects of currency exchange rate fluctuations on certain receivables or payables denominated in currencies other than the functional currencies of its subsidiaries. These contracts generally mature within approximately one month. The primary risk managed by using forward and swap contracts is the currency exchange rate risk. The gains or losses on these contracts are not material and are included in other income (expense), net, in the condensed consolidated statements of operations based on the changes in fair value. The notional amounts of these contracts outstanding as of September 30, 2025 and March 31, 2025 were $129.5 million and $131.8 million, respectively.
 
The fair value of all foreign currency exchange forward and swap contracts is determined based on observable market transactions of spot currency rates and forward rates. Cash flows from these contracts are classified as operating activities in the condensed consolidated statements of cash flows.

On January 27, 2025, the Company entered into an unsecured revolving credit facility with a syndicate of banks (the "Credit Agreement"). The Credit Agreement provides a revolving line of credit of up to $750.0 million to the Company including the issuance of letters of credit of up to $100.0 million. The Credit Agreement terminates on January 27, 2030 unless extended in accordance with its terms. The Credit Agreement contains (1) an increase option allowing the Company to secure up to $250.0 million of additional commitments and (2) an extension option to extend the term by one-year which may be exercised no more than two times, subject to certain requirements. Loans under the Credit Agreement are available in U.S. Dollars, Euro, Sterling, Yen, Swiss Francs, Canadian Dollars, Australian Dollars and any other currency agreed to by each lender. Proceeds of loans made under the Credit Agreement may be used for general corporate purposes.

The Credit Agreement contains a maximum net debt to adjusted EBITDA ratio, compliance with which is a condition to the Company's ability to borrow. Borrowings under the Credit Agreement will bear interest at a rate determined by reference to benchmark rates plus an applicable spread (ranging from 0% to 1.5%) based on the Company's net leverage ratio or credit rating at the time of the borrowing. Undrawn balances available under the Credit Agreement are subject to commitment fees at the applicable rate determined by reference to the Company's net leverage ratio or credit rating. There has been no borrowing outstanding under the Credit Agreement as of September 30, 2025.
In addition, the Company had several uncommitted, unsecured bank lines of credit and letters of credit aggregating to $160.9 million and $172.2 million as of September 30, 2025 and March 31, 2025, respectively. There are no financial covenants under the lines of credit with which the Company must comply. There was no borrowing outstanding under the lines of credit as of September 30, 2025 or March 31, 2025. As of September 30, 2025 and March 31, 2025, the Company had outstanding bank guarantees of $11.7 million and $12.1 million, respectively.

Indemnifications
 
The Company indemnifies certain of its suppliers and customers for losses arising from matters such as intellectual property disputes and product safety defects, subject to certain restrictions. The scope of these indemnities varies, but in some instances includes indemnification for damages and expenses, including reasonable attorneys’ fees. As of September 30, 2025, no material amounts have been accrued for these indemnification provisions. The Company does not believe, based on historical experience and information currently available, that it is probable that any material amounts will be required to be paid under its indemnification arrangements.
 
The Company also indemnifies its current and former directors and certain of its current and former officers. Certain costs incurred for providing such indemnification may be recoverable under various insurance policies. The Company is unable to reasonably estimate the maximum amount that could be payable under these arrangements because these exposures are not limited, the obligations are conditional in nature, and the facts and circumstances involved in any situation that might arise are variable.

Legal Proceedings

From time to time the Company is involved in claims and legal proceedings that arise in the ordinary course of its business. The Company is currently subject to several such claims and legal proceedings. The Company intends to vigorously defend against them. Management periodically assesses the Company’s liabilities and contingencies in connection with these matters based upon the latest information available. The Company follows ASC ("Accounting Standards Codification") 450, Contingencies, in determining the accounting and disclosure for these contingencies. Based on currently available information, the Company does not believe that resolution of pending matters will have a material adverse effect on its financial condition, cash flows, and results of operations. However, litigation is subject to inherent uncertainties, and there can be no assurances that the Company's defenses will be successful or that any such lawsuit or claim would not have a material adverse impact on the Company's business, financial condition, cash flows and results of operations in a particular period. Any claims or proceedings against the Company can have an adverse impact because of defense costs, diversion of management and operational resources, negative publicity, and other factors. Any failure to obtain a necessary license or other rights, or litigation arising out of intellectual property claims, could adversely affect the Company's business.

At the 2023 Annual General Meeting ("AGM"), the Company's shareholders approved an amendment to the Company’s Articles of Incorporation to introduce a capital band provision authorizing the Board of Directors to adjust the Company's share capital, without additional shareholder approval, within a range of 155,795,958 registered shares to 190,417,282 registered shares for a five-year period ending on September 13, 2028. At the 2025 AGM, the Company's shareholders approved a renewal of the capital band, setting a new range of 144,706,014 registered shares to 176,862,906 registered shares for a five-year period ending on September 9, 2030. The amendment became effective on October 1, 2025.

In addition, the Company has reserved conditional capital (1) up to 25,000,000 shares for potential issuance for the exercise of rights granted under the Company's employee equity incentive plans, and (2) up to 25,000,000 shares for issuance to cover any conversion rights under any potential future convertible bond issuance.

Share Repurchases

In June 2023, the Company's Board of Directors approved a three-year share repurchase program, which allows the Company to use up to $1.0 billion to repurchase its shares. The 2023 share repurchase program enables the Company to repurchase shares for cancellation, as well as to support equity incentive plans or potential acquisitions. The Swiss Takeover Board approved the 2023 share repurchase program in July 2023 and the program became effective on July 28, 2023. In March 2025, the Company's Board of Directors approved an
increase of $600.0 million to the 2023 share repurchase program, to an aggregate amount of $1.6 billion. The Swiss Takeover Board approved this increase in April 2025 and it became effective on April 2, 2025. As of September 30, 2025, $432.7 million was available for repurchase under the 2023 share repurchase program.

The following table summarizes the Company's share repurchase activities for the six months ended September 30, 2025 and 2024 were as follows (in thousands):

(1) All shares were repurchased for cancellation.
(2) Includes an aggregate cost of $6.3 million and $18.4 million, respectively, that was not yet paid as of September 30, 2025 and 2024.

Swiss law limits a company’s ability to hold or repurchase its own shares. The aggregate par value of all shares held in treasury by the Company and its subsidiaries may not exceed 10% of the share capital of the Company, which for the Company corresponds to approximately 16.1 million registered shares as of September 30, 2025. This limitation does not apply to shares repurchased for cancellation, due to the Board of Directors’ authority under the Company’s capital band set forth in the Company’s Articles of Incorporation. As of September 30, 2025, the Company had a total of 13.9 million shares held in treasury stock, which includes 0.9 million shares that have been repurchased for cancellation and 13.0 million shares that have been purchased to support equity incentive plans or potential acquisitions.

To the extent that the shares are repurchased to support equity incentive plans or potential acquisitions, the shares are repurchased on the ordinary trading line of SIX Swiss Exchange (“SIX”) and/or The Nasdaq Global Select Market (“Nasdaq”). Shares repurchased for cancellation purposes are repurchased on a second trading line on SIX. Shares may be repurchased from time to time on the open market or in privately negotiated transactions, including under plans complying with the provisions of Rule 10b5-1 and Rule 10b-18 of the Securities Exchange Act of 1934, as amended. Purchases may be started or stopped at any time without prior notice depending on market conditions and other factors and the program does not require the purchase of any minimum number of shares.

Share Cancellation

In June 2025, the Company's Board of Directors approved the cancellation of 8.2 million treasury shares, which were repurchased under the 2023 share repurchase program in fiscal year 2025 and the first quarter of fiscal year 2026, for an aggregate cost of $712.2 million. The cancellation became effective in the second quarter of fiscal year 2026, and as a result, both the number of registered shares issued and the number of treasury shares decreased by 8.2 million shares. Upon cancellation of these shares, the Company deducted the par value from registered shares and reflected the excess of share repurchase cost over par value as a reduction to retained earnings.

Dividends

During the three and six months ended September 30, 2025, the Company declared cash dividends of CHF 1.26 (USD equivalent of $1.58 based on the exchange rate on the date of declaration) per share and paid a total of $233.1 million on the Company's outstanding shares. During the three and six months ended September 30, 2024, the Company declared cash dividends of CHF 1.16 (USD equivalent of $1.37 based on the exchange rate on the date of declaration) per share and paid a total of $207.9 million on the Company's outstanding shares.

Any future dividends will be subject to approval of the Company's shareholders.

Accounting Policies [Abstract]  
Basis of Presentation and Changes in Significant Accounting Policies
Basis of Presentation
The condensed consolidated financial statements include the accounts of Logitech and its subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and therefore do not include all the information required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for the fiscal year ended March 31, 2025, included in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on May 23, 2025.
In the opinion of management, these condensed consolidated financial statements include all adjustments, consisting of only normal and recurring adjustments, necessary and in all material aspects, for a fair statement of the results of operations, comprehensive income, financial position, cash flows and changes in shareholders' equity for the periods presented. Operating results for the three and six months ended September 30, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2026, or any future periods.
Changes in Significant Accounting Policies
There have been no material changes in the Company’s significant accounting policies during the three and six months ended September 30, 2025 compared with the significant accounting policies described in its Annual Report on Form 10-K for the fiscal year ended March 31, 2025.
Use of Estimates
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Significant estimates and assumptions made by management involve the fair value of goodwill and intangible assets acquired from business acquisitions, pension obligations, accruals for customer incentives, cooperative marketing, and pricing programs and related breakage when appropriate, inventory valuation, share-based compensation expense, uncertain tax positions, and valuation allowances for deferred tax assets. Although these estimates are based on management’s best knowledge of current events and actions that may impact the Company in the future, actual results could differ materially from those estimates.
Risks and Uncertainties
Risks and Uncertainties
Impacts of Macroeconomic and Geopolitical Conditions on the Company's Business
In 2025, the United States introduced trade policy actions that have increased import tariffs across a wide range of countries at various rates, with certain exemptions. These tariff policies in the U.S. and responsive policies enacted in other countries are evolving. The incremental tariffs have had and may continue to have an adverse impact on the Company's results of operations. In addition, the Company's business has continued to be impacted by ongoing macroeconomic and geopolitical conditions. These conditions include inflation, interest rate and foreign currency fluctuations, uncertainty in consumer and enterprise demand, low economic growth in certain regions, changes in fiscal policies and geopolitical conflicts.
The global and regional economic and political conditions, as well as changes in trade policies, have caused and may continue to cause volatility in demand for the Company's products as well as the cost of tariffs, materials and logistics, and transportation delays, and as a result have impacted and may continue to impact the pricing of the Company's products, product availability and the Company's results of operations.
