Through multiple acquisitions, we acquired definite-lived intangible assets consisting primarily of customer relationships, developed technology and patents, distribution networks, and trademarks and trade names associated with specific products, which are amortized over their estimated useful lives. Indefinite-lived intangible assets consist of trade names that are expected to generate cash flows indefinitely.

We recorded amortization expense for definite-lived intangible assets of $23.0 million and $20.0 million during the three months ended May 31, 2026 and May 31, 2025, respectively and $70.4 million and $45.5 million during the nine months ended May 31, 2026 and May 31, 2025, respectively.
