Change in Inventory Accounting Method

During the fourth quarter of fiscal 2026, the Company elected to change its method of accounting for certain inventories from the last-in, first out (LIFO) method to the first-in, first out (FIFO) method. The change to the FIFO method of accounting for these inventories is preferable because it provides better matching of costs and revenues, conforms the Company's inventory to a single method of accounting and improves comparability with the Company's peers. The impact of the change in inventory accounting as reported under the FIFO method was a $32.1 million increase in inventory for the fiscal year ended June 30, 2025, and the amounts in this press release reflect the impact of this accounting change. To provide historical information on a basis consistent with the change to FIFO, the Company has recast certain historical information to conform to the updated method of inventory accounting in the financial tables of this press release.
