Cash and cash equivalents were $120 million, an increase of $13 million, or 12.3%.

Inventory was $280 million, an increase of $1 million, or 0.4%.

Net Debt was $519 million, a decrease of $85 million, or 14.1%.

FULL-YEAR 2026 OUTLOOK

The Company's outlook reflects the impact of foreign currency. Additionally, fiscal 2026 is a 52-week year and fiscal 2025 was a 53-week year, which will affect annual comparisons.

For fiscal year 2026, the Company currently expects:

•Revenue to be approximately $1.960 billion to $1.985 billion. This range is unchanged from the previous outlook and represents growth of approximately 4.6% to 5.9% compared to 2025, constant currency growth of approximately 3.8% to 5.1%, and constant currency growth of approximately 4.5% to 5.8% excluding the impact of the 53rd week in 2025.

•Gross margin to be approximately 46.4%, down 90 basis points compared to 2025. This compares to the previous gross margin outlook of approximately 46.0%.

•Operating margin to be approximately 9.2%, up 120 basis points compared to 2025, and adjusted operating margin to be approximately 9.5%, up 50 basis points compared to 2025. This compares to the previous operating margin outlook of approximately 8.8% and adjusted operating margin of approximately 9.1%.

•The effective tax rate to be approximately 18.0%, unchanged from the previous outlook.

•Diluted earnings per share in the range of $1.39 to $1.54 and adjusted diluted earnings per share in the range of $1.43 to $1.58. This compares to the previous outlook for diluted earnings per share in the range of $1.31 to $1.46 and adjusted diluted earnings per share in the range of $1.35 to $1.50.

•Diluted weighted average shares of approximately 82.0 million. This compares to the previous outlook for diluted weighted average shares of approximately 81.5 million.

NON-GAAP FINANCIAL MEASURES

Measures referred to in this release as “adjusted” financial results and the financial results of the "ongoing business" are non-GAAP measures. Adjusted financial results exclude environmental and other related costs net of recoveries, reorganization costs, and other costs not related to the Company's ongoing business. The Company also presents constant currency information, which is a non-GAAP measure that excludes the impact of fluctuations in foreign currency exchange rates. The Company calculates constant currency basis by converting the current-period local currency financial results using the prior period exchange rates and comparing these adjusted amounts to the Company's current period reported results. The Company believes providing each of these non-GAAP measures provides valuable supplemental information regarding its results of operations, consistent with how the Company evaluates performance.

The Company has provided a reconciliation of each of the above non-GAAP financial measures to the most directly comparable GAAP financial measure. The Company believes these non-GAAP measures provide useful information to both management and investors because they increase the comparability of current period results to prior period results by adjusting for certain items that may not be indicative of core operating results and enable better identification of trends in our business. The adjusted financial results are used by management to, and allow investors to, evaluate the operating performance of the Company on a comparable basis. Management does not, nor should investors, consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP.

EARNINGS CALL INFORMATION

The Company will host a conference call today at 8:30 a.m. ET to discuss these results and current business trends. The conference call will be broadcast live and accessible under the “Investor Relations” tab at www.wolverineworldwide.com. A replay of the conference call will be available on the Company’s website for a period of approximately 30 days.

*To supplement the consolidated condensed financial statements presented in accordance with Generally Accepted Accounting Principles ("GAAP"), the Company describes what certain financial measures would have been if environmental and other related costs net of recoveries, reorganization costs, and other costs not related to the Company's ongoing business were excluded. The Company believes these non-GAAP measures provide useful information to both management and investors by increasing comparability to the prior period by adjusting for certain items that may not be indicative of the Company's core ongoing operating business results and to better identify trends in the Company's ongoing business. The adjusted financial results are used by management to, and allow investors to, evaluate the operating performance of the Company on a comparable basis.

The constant currency presentation, which is a non-GAAP measure, excludes the impact of fluctuations in foreign currency exchange rates. The Company believes providing constant currency information provides valuable supplemental information regarding results of operations, consistent with how the Company evaluates performance. The Company calculates constant currency by converting the current-period local currency financial results using the prior period exchange rates and comparing these adjusted amounts to the Company's current period reported results.

Management does not, nor should investors, consider such non-GAAP financial measures in isolation from, or as a substitution for, financial information prepared in accordance with GAAP.  A reconciliation of all non-GAAP measures included in this press release, to the most directly comparable GAAP measures are found in the financial tables above.
