Additionally, depreciation expense on property, plant and equipment was $74.3 million and $75.5 million for the nine months ended September 30, 2024, and 2023, respectively.

In the first quarter of 2023, the Company recorded a $87.2 million impairment charge related to ELEMENT. The plant faced operational and market-based challenges which were exacerbated by a shift in the California Low Carbon Fuel Standard credit markets and high western corn basis. At the time of the impairment, the Company owned 51% of ELEMENT and it was a consolidated entity, as such, 49% of the impairment charge was represented in Net income attributable to noncontrolling interests in the Company's Condensed Consolidated Statements of Operations.
