Income Taxes Income Taxes* 
Income tax benefit from continuing operations for the three months ended March 31, 2026 was $24.4 million compared with $2.0 million income tax expense for the three months ended March 31, 2025. The change is primarily due to costs of $12.5 million related to the planned sale of Clean Earth during the three months ended March 31, 2026, which did not occur during the three months ended March 31, 2025, lower operating income in Clean Earth and a $5.1 million tax benefit from the vesting of stock-based compensation awards in 2026.

The reserve for uncertain tax positions on March 31, 2026 and December 31, 2025 was $6.0 million and $6.7 million, respectively, including interest and penalties. Within the next twelve months, it is reasonably possible that $2.0 million in unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.
