The Company’s mining and exploration activities are subject to various domestic and international laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. The Company conducts its operations to protect public health and the environment and believes its operations are in compliance with applicable laws and regulations in all material respects. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of such future expenditures. Estimated future reclamation and remediation costs are based principally on current legal and regulatory requirements.

(1)The addition to remediation for the nine months ended September 30, 2026 was primarily related to project execution delays and revised productivity assumptions for Phase 3 closure activities at the Midnite Mine. The addition to reclamation for the nine months ended September 30, 2025 was primarily related to NGM, as a result of higher water management costs and higher mercury storage and disposal costs at the Carlin mine. The addition to remediation for the nine months ended September 30, 2025 was primarily related to higher water management costs and project execution delays at the Midnite Mine.

(2)In the third quarter of 2026, the Company completed the sale of a historical mining site that was in the closure phase and was previously included within Corporate and Other. Refer to Note 3 for information on divestitures completed in 2025.

____________________________

The Company is also involved in several matters concerning environmental remediation obligations associated with former, primarily historic, mining activities. Generally, these matters concern developing and implementing remediation plans at the various sites involved. The amounts accrued are reviewed periodically based upon facts and circumstances available at the time. Changes in estimates are recorded in Other current liabilities and Reclamation and remediation liabilities in the period estimates are revised.
