The Company completes its annual impairment assessment of goodwill on October 31 of each fiscal year. The Company has concluded that it has one reporting unit. Management continues to closely monitor the results of the Company’s business, the performance of the Company’s common stock, current liquidity and key assumptions used in its fair value estimate, in addition to operational initiatives and macroeconomic conditions, which may impact the results of

the Company’s goodwill impairment assessment. The projected performance of the reporting unit, including the need for additional financing to fund the operations of the Company’s business for the next twelve months and the potential for future developments in the global economic environment, introduces a heightened risk for impairment in the Company’s goodwill, intangible assets and property, plant and equipment. If the Company cannot improve its current operating levels and meet its operating targets to achieve the growth and margin assumptions and/or if the Company is not able to obtain the additional financing required to fund its business for the next twelve months, some or all of the recorded goodwill, intangible assets and property, plant and equipment as of September 30, 2023 could be subject to impairment. Such potential impairment of goodwill, intangible assets and property, plant and equipment could be material to the Company’s condensed consolidated financial statements.
