Weichai Transactions

Weichai Shareholder’s Loan Agreements

The Company is party to four shareholder’s loan agreements with Weichai, including the $130.0 million first Amended Shareholder’s Loan Agreement, the $25.0 million second Amended Shareholder’s Loan Agreement, the $50.0 million third Amended Shareholder’s Loan Agreement, and the $30.0 million fourth Amended Shareholder’s Loan Agreement. See additional discussion of these debt agreements in Note 6. Debt.

Weichai Collaboration Arrangement and Other Related Party Transactions

The Company and Weichai executed a strategic collaboration agreement (the “Collaboration Agreement”) on March 20, 2017, in order to achieve their respective strategic objectives and enhance the strategic cooperation alliance to share experiences, expertise and resources. The Collaboration Agreement was extended for three years in March 2020 and was set to expire in March 2023. On March 22, 2023, the Collaboration Agreement was extended for an additional term of three years.

The Company evaluates whether an arrangement is a collaborative arrangement at its inception based on the facts and circumstances specific to the arrangement. The Company also reevaluates whether an arrangement qualifies or continues to qualify as a collaborative arrangement whenever there is a change in either the roles of the participants or the participants’ exposure to significant risks and rewards dependent on the ultimate commercial success of the endeavor. For those collaborative arrangements where it is determined that the Company is the principal participant, costs incurred and revenue generated from third parties are recorded on a gross basis in the financial statements. The Company purchased $6.2 million and $13.3 million of inventory from Weichai during 2023 and 2022, respectively.

In January 2022, PSI and Baudouin, a subsidiary of Weichai, entered into an international distribution and sales agreement which enables Baudouin to bring PSI’s power systems line of products into the European, Middle Eastern, and African markets. In addition to sales, Baudouin will manage service, support, warranty claims, and technical requests. Refer to the Consolidated Balance Sheet and Statements of Income for detailed related party information.
