During the three and six months ended June 30, 2026, the Company contributed $0.6 million to its qualified pension plan.

The Company has established a Voluntary Employees’ Beneficiary Association (VEBA) trust to pre-fund a portion of benefits for non-represented retirees. The Company does not expect to make any discretionary contributions to the VEBA trust in 2026 and plans to utilize a portion of VEBA assets to make certain benefit payments.

In July 2026, the Company announced changes to its postretirement health care benefit plan for non-represented employees and retirees. Effective December 31, 2026, the Company will no longer provide a medical reimbursement benefit to certain existing employees and retirees. As of June 30, 2026, the net health care benefit obligation attributed to these certain existing employees and retirees was approximately $21.6 million. The impact of the changes will reduce the Company’s postretirement benefit obligation during the third quarter of 2026. The liability is expected to be remeasured, with the resulting benefit of the plan changes recorded in “Accumulated other comprehensive income” and amortized to future earnings based upon the remaining life of the plan.
