SEACOR Marine Holdings Inc.

MNOPF and MNRPF. Certain of the Company’s subsidiaries are participating employers in two industry-wide, multi-employer, defined benefit pension funds in the U.K.: the MNOPF and the MNRPF.

The Company’s participation in the MNOPF began with the acquisition of the Stirling group of companies (the “Stirling Group”) in 2001 and relates to certain officers employed between 1978 and 2002 by the Stirling Group and/or its predecessors. The Company’s participation in the MNRPF also began with the acquisition of the Stirling Group in 2001 and relates to ratings employed by the Stirling Group and/or its predecessors through today. Both of these plans are in deficit positions and, depending upon the results of future actuarial valuations, it is possible that the plans could experience funding deficits that will require the Company to recognize payroll related operating expenses in the periods invoices are received. As of December 31, 2025, all invoices received related to MNOPF and MNRPF have been settled in full.

On October 19, 2021, the Company was informed by the MNRPF that two issues had been identified during a review of the MNRPF by the applicable trustee that would potentially give rise to material additional liabilities for the MNRPF. On November 23, 2023, the trustee advised that following the tri-annual valuation, $1.5 million (£1.2 million) of the potential cumulative funding deficit of the MNRPF was allocated to the Company as a participating employer, including the additional liabilities mentioned above. During 2023, the Company recognized payroll related operating expenses of $1.5 million (£1.2 million) for its allocated share of the potential cumulative funding deficit, which the Company anticipated being invoiced for during 2024 and 2025. On April 30, 2024, the Company was informed by the MNRPF that the Company’s allocated share of the potential cumulative funding deficit may be reduced due to changes in valuation assumptions, and on July 5, 2024, the Company was informed by the MNRPF that the Company’s final deficit share amount was $0.4 million (£0.3 million) and the Company recognized a reduction in the payroll related operating expenses of $1.2 million (£0.9 million) to reflect the decreased deficit share amount. All invoices were settled in full in October 2024.

Other. In the normal course of its business, the Company becomes involved in various other litigation matters including, among others, claims by third parties for alleged property damages and personal injuries. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its financial statements related thereto where appropriate. It is possible that a change in the Company’s estimates of that exposure could occur, but the Company does not expect such changes in estimated costs would have a material effect on the Company’s consolidated financial position, results of operations or cash flows.
