[1] On May 29, 2024, we entered into an agreement with Hexagon and contributed the net assets of our Sustainable Energy Solutions business to a newly-formed joint venture in which we retained a 49% noncontrolling interest. As a result, we recognized a pre-tax loss of $30,502 within restructuring and other expense, net, including closing costs.
[2] During fiscal 2024, we reversed amounts accrued for the anticipated payout under the final earnout opportunity associated with the Level5 acquisition.
[3] Significant pre-tax restructuring charges include a loss of $30,502 in the fourth quarter of fiscal 2024 due to the deconsolidation of our former Sustainable Energy Solutions operating segment during the fourth quarter of fiscal 2024.
