Inventories are valued at the lower of cost or market. Cost for inventories is principally determined using the last-in, first-out ("LIFO") inventory costing method. The Company values other inventory at the lower of cost or net realizable value, determined by the first-in, first-out and average cost methods. As of September 30, 2026 and June 30, 2026, $165.7 million and $162.6 million of inventory, respectively, was accounted for using a method other than the LIFO inventory costing method.
