Design, Chris-Craft, Newmar and Barletta brands, which are used primarily in leisure travel and outdoor recreation activities. We also design and manufacture advanced battery solutions that deliver “house power,” supporting internal electrical features and appliances for a variety of outdoor products including RVs, boats, specialty and other low-speed vehicles, as well as other industrial applications. Other products manufactured by us consist primarily of original equipment manufacturing parts for other manufacturers and commercial vehicles. We produce our motorhome RV units in Iowa and Indiana; our towable RV units in Indiana; our marine units in Indiana and Florida; and our battery solutions in Florida. We distribute our RV and marine products primarily through independent dealers across the U.S. and Canada, who then retail the products to the end consumer. We also distribute our marine products internationally through independent dealers, who then retail the products to the end consumer. Our battery solutions are primarily sold to customers in the U.S.

The consolidated financial statements include the accounts of Winnebago Industries, Inc. and its wholly-owned subsidiaries. Intercompany account balances and transactions have been eliminated in consolidation. The use of the terms "Winnebago Industries," "Winnebago," "we," "our," and "us" in this Annual Report on Form 10-K, unless the context otherwise requires, refer to Winnebago Industries, Inc. and its wholly-owned subsidiaries.

We have a 5-4-4 quarterly accounting cycle with the fiscal year ending on the last Saturday in August. All references to Fiscal 2025 refer to the 52-week period ended August 30, 2025. Fiscal 2024 refers to the 53-week period ended August 31, 2024 and Fiscal 2023 refers to the 52-week period ended August 26, 2023.

In conjunction with the Grand Design RV entrance into the motorized RV category, we established a Grand Design motorhomes operating segment in the first quarter of Fiscal 2025. This newly created operating segment is included in the Motorhome RV reportable segment. Prior period amounts have not been reclassified as the impact was not significant.

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting years. Actual results could differ from those estimates.

We record an allowance using a model to reduce receivables by the expected credit loss and consider factors such as financial condition of the dealer, specific collection issues, current and expected economic conditions, and other factors that may impact our ability to collect. If there is a deterioration of a dealer's financial condition, if we become aware of additional information related to credit worthiness, or if future actual default rates on receivables differ from those currently anticipated, we may adjust the allowance for credit losses, which would affect earnings in the period the adjustments are made.

Generally, inventories are stated at the lower of cost or net realizable value determined under the First-in, First-out basis ("FIFO"), except for the Winnebago Motorhome operating segment which is determined using the Last-in, First-out ("LIFO") basis. Manufacturing cost includes materials, labor, and overhead. Unallocated overhead and abnormal costs are expensed as incurred.

Goodwill is tested for impairment at least annually, during the fourth quarter and whenever events occur or circumstances change that would indicate the carrying value may not be recoverable. Impairment testing for goodwill is performed at a reporting unit level and all goodwill is assigned to a reporting unit. Our reporting units are the same as the operating segments as defined in Note 3 in the Notes to Consolidated Financial Statements, included in Item 8 of Part II in this Annual Report on Form 10-K.

We have the option to first assess qualitative factors to determine whether the fair value of a reporting unit is “more likely than not” less than its carrying value. If it is more likely than not that an impairment has occurred, we then perform the quantitative goodwill impairment test. We also generally perform a quantitative impairment test of our reporting units at least once every five years. If we perform the quantitative test, the carrying value of the reporting unit is compared to an estimate of the reporting unit’s fair value to identify impairment. The estimate of the reporting unit’s fair value involves significant unobservable inputs (Level 3 inputs). The fair value is determined by a blend of the income approach (discounted future cash flow) and market approach (guideline public company) using current industry information. In determining the estimated future cash flow, we consider and apply certain estimates and judgments, including current and projected future levels of income based on management plans, business trends, prospects, market and economic conditions, and market-participant considerations. If the quantitative assessment of goodwill impairment fails, an impairment loss equal to the amount that a reporting unit's carrying value exceeds its fair value will be recognized.

During the fourth quarter of Fiscal 2025, we completed our annual goodwill impairment testing. We elected to rely on a qualitative assessment for the Grand Design, Barletta, and Lithionics reporting units, and performed a quantitative analysis for the Newmar reporting unit. No impairment was identified for the fiscal year ended August 30, 2025. For the fiscal year ended August 31, 2024, the results of our goodwill impairment testing indicated that the carrying value of the Chris-Craft reporting unit exceeded its fair value, resulting in a $30.3 million impairment charge, which represents the full goodwill balance attributable to the reporting unit. No impairment was identified for the fiscal year ended August 26, 2023. For further information regarding the Fiscal 2024 impairment charge, refer to Note 7 in the Notes to Consolidated Financial Statements, included in Item 8 of Part II in this Annual Report on Form 10-K.

We have indefinite-lived intangible assets related to the Newmar trade name within the Motorhome RV segment, the Grand Design trade name within the Towable RV segment, and the Chris-Craft and Barletta trade names within the Marine segment. We also have a finite-lived trade name intangible asset related to Lithionics within Corporate / All Other. Annually in the fourth quarter, or if conditions indicate an interim review is necessary, we test indefinite-lived trade names for impairment. We have the option to first assess qualitative factors to determine whether the fair value of a trade name is “more likely than not” less than its carrying value. If it is more likely than not that an impairment has occurred, we then perform the quantitative impairment test. If we perform the quantitative test, the carrying value of the asset is compared to an estimate of its fair value to identify impairment. The fair value is determined by the relief-from-royalty method, which requires significant judgment. Actual results may differ from assumed and estimated amounts utilized in the analysis. If we conclude an impairment exists, the asset's carrying value will be written down to its fair value.

During the fourth quarter of Fiscal 2025, we completed the annual impairment testing for indefinite-lived intangible assets. We elected to rely on a qualitative assessment for the Grand Design, and Barletta trade names, and performed a quantitative analysis for the Chris-Craft and Newmar trade names. No impairment was identified for the fiscal years ended August 30, 2025, August 31, 2024, or August 26, 2023.

Long-lived assets, which include property, plant and equipment, finite-lived intangible assets subject to amortization, and right-of-use assets are assessed for impairment whenever events or changes in circumstances such as asset utilization, physical change, legal factors or other matters indicate the carrying value of those assets may not be recoverable from future undiscounted cash flows. The impairment test involves comparing the carrying amount of the asset to the forecasted undiscounted future cash flows

generated by that asset. These assumptions require significant judgment and actual results may differ from assumed and estimated amounts. In the event the carrying amount of the asset exceeds the undiscounted future cash flows generated by that asset and the carrying amount is not considered recoverable, an impairment exists. An impairment loss is measured as the excess of the asset’s carrying amount over its fair value and is recognized in the statement of income in the period that the impairment occurs. The reasonableness of the useful lives of the asset and other long-lived assets is regularly evaluated.

Generally, we self-insure a portion of health insurance, product liability claims, and workers' compensation. We maintain insurance programs subject to applicable deductibles or retentions. Under these plans, liabilities are recognized for claims incurred, including those incurred but not reported. We use third-party administrators and actuaries who use historical claims experience and various state statutes to assist in the determination of the accrued liability balance. We review the valuations provided by the third-party administrators and actuaries to determine the adequacy of the reserves. Any material change in the aforementioned factors could have an adverse impact on operating results. Balances are included within self-insurance (accrued expenses) on the Consolidated Balance Sheets.

In preparing these financial statements, we are required to estimate the income taxes in each of the jurisdictions in which we operate. This process involves estimating the current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These temporary differences result in deferred tax assets and liabilities, which are included on the Consolidated Balance Sheets. We then assess the likelihood that the deferred tax assets will be realized based on future taxable income and, to the extent that recovery is not likely, a valuation allowance is established. To the extent we establish a valuation allowance or change this allowance in a period, an expense or a benefit is included within the tax provision on the Consolidated Statements of Income.

Our primary source of revenue is generated through the sale of non-motorized towable RV units, motorhome RV units, and marine units to our independent dealer network (customers). Unit revenue is recognized at a point-in-time when the performance obligation is satisfied and control of the promised goods or services is transferred to the customer, which occurs when the unit is shipped to or picked-up from the manufacturing facilities by the customer. Control refers to the ability of the customer to direct the use of, and obtain substantially all of, the remaining benefits from the goods or services. We recognize revenue based on an amount that reflects the transaction price consideration that we expect to receive in exchange for those goods or services. Our transaction price consideration is fixed, unless otherwise disclosed as variable consideration. The amount of consideration received and recorded to revenue can vary with changes in marketing incentives and discounts offered to customers. These marketing incentives and discounts are considered variable consideration. We adjust the estimate of revenue at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. Our payment terms are typically before or on delivery, and do not include a significant financing component.

Net revenue includes shipping and handling charges billed directly to customers, and we also generate income through the sale of certain parts and services, acting as the principal in these arrangements. We have made an accounting policy election to account for any shipping and handling costs that occur after the transfer of control as a fulfillment cost that is accrued when control is transferred. We also have made an accounting policy election to exclude from revenue sales and usage-based taxes collected.

Our contracts include some incidental items that are immaterial in the context of the contract. We have made an accounting policy election to not assess whether promised goods or services are performance obligations if they are immaterial in the context of the contract with the customer. Warranty obligations associated with the sale of a unit are assurance-type warranties that are a guarantee of the unit’s intended functionality and, therefore, do not represent a distinct performance obligation within the context of the contract. Contract costs incurred related to the sale of manufactured units are expensed at the point-in-time when the related revenue is recognized.

The revenue standard requirements are applied to a portfolio of contracts (or performance obligations) with similar characteristics for transactions where it is expected that the effects on the financial statements of applying the revenue recognition guidance to the portfolio would not differ materially from applying this guidance to the individual contracts (or performance obligations) within that portfolio.

Advertising costs, which consist primarily of trade shows and online content, were $20.9 million, $21.9 million, and $21.3 million in Fiscal 2025, 2024, and 2023, respectively. Advertising costs are included in selling, general, and administrative expenses and are expensed as incurred on the Consolidated Statements of Income.

Comprehensive income represents the change in stockholders’ equity from transactions and other events and circumstances from sources other than shareholders. The difference between comprehensive income and net income was not material for the fiscal years ended August 30, 2025, August 31, 2024, and August 26, 2023.

In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires incremental disclosures about significant segment expenses regularly provided to the Chief Operating Decision Maker. We adopted the new standard and applied the amendments retrospectively to all prior periods presented in our consolidated financial statements beginning with our annual reporting for the fiscal year ended August 30, 2025 and filings hereafter. Adoption of the new standard did not have a material impact on our consolidated results of operations, financial position or cash flows. The incremental disclosures required under the standard appear in Note 3 in the Notes to Consolidated Financial Statements, included in Item 8 of Part II in this Annual Report on Form 10-K.

In November 2024, the Financial Accounting Standards Board (“FASB”) issued ASU 2024-04, Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which clarifies the assessment of whether certain settlements of convertible debt instruments should be accounted for as an inducement conversion or extinguishment of convertible debt. The new guidance is effective for annual reporting periods beginning after December 15, 2025, and interim periods within those annual periods. We are currently evaluating the impact of the standard on our consolidated financial statements and related disclosures. We will adopt the standard in our Annual Report on Form 10-Q for our fiscal year beginning August 30, 2026 and filings thereafter.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation Of Income Statement Expenses, which requires disclosure of additional disaggregated information about significant expenses within relevant income statement captions, such as purchases of inventory, employee compensation, depreciation, amortization and depletion. The new guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. We are currently evaluating the impact of the standard on our consolidated financial statements and related disclosures. We will adopt the standard in our Annual Report on Form 10-K for our fiscal year ending August 26, 2028 and filings thereafter.
