Per the terms of their Transition Support Services agreement, which may be terminated by either party, RPC provides certain administrative services, including financial reporting and income tax administration, acquisition assistance, etc., to Marine Products. Charges from RPC (or from corporations that are subsidiaries of RPC) for such services were $1.1 million in 2025, $1.1 million in 2024 and $1.0 million in 2023. The Company’s payable to RPC for these services was $58 thousand as of December 31, 2025 and $99 thousand as of December 31, 2024.

All of the Company’s directors are also directors of RPC and the Company’s executive officers are employees of both the Company and RPC.

RPC and Marine Products own 50% each of a limited liability company called 255 RC, LLC that was created for the joint purchase and ownership of a corporate aircraft. The purchase was funded primarily by a $2.6 million contribution by each company to 255 RC, LLC. Each of RPC and Marine Products is currently a party to an operating lease agreement with 255 RC, LLC for a period of five years. Marine Products recorded certain net operating costs for the corporate aircraft comprised of rent and an allocable share of fixed costs of $141 thousand in 2025, $188 thousand in 2024 and $160 thousand in 2023. The Company has a payable to 255 RC, LLC of $2.2 million as of December 31, 2025 and $2.0 million as of December 31, 2024. The Company accounts for this investment using the equity method and its proportionate share of income or loss is recorded in selling, general and administrative expenses. As of December 31, 2025, the investment closely approximates the underlying equity in the net assets of 255 RC, LLC and the undistributed earnings represented in retained earnings was $757 thousand.
