#### Change in Fiscal Year
Through October 31, 2024, our fiscal years began on November 1 and ended on October 31 of the following year. Any references in this Form 10-KT to fiscal 2024 or any prior fiscal years, or to any quarter of those fiscal years, relates to the fiscal year or quarter, as the case may be, ended in that year, unless otherwise stated.

We changed our fiscal year end to September 30, effective for the 2025 fiscal year. Our 2025 fiscal year began on November 1, 2024 and ended on September 30, 2025, and accordingly, consisted of eleven months (“fiscal 2025”). Our fourth fiscal quarter of 2025 was a two-month period ended September 30, 2025. Thereafter, our fiscal year will begin on October 1 and end on September 30 of the following year.

In Item 7 of this Form 10-KT, when financial results for fiscal 2025 are compared to financial results for fiscal 2024, the results for the 11-month transition period are compared to the results of the comparable 11-month recast period from fiscal 2024. When financial results for fiscal 2024 are compared to financial results for fiscal 2023, the results are presented based on our previous fiscal year-end on a 12-month basis.
