On December 29, 2018, Microvast Power Systems Co., Ltd.(“MPS”), one of the Company’s subsidiaries, signed an agreement with Huzhou Saiyuan, an entity established by the local government, to issue convertible bonds to Huzhou Saiyuan for a total consideration of $87,776 (RMB600 million). The Company pledged its 12.39% equity holding over MPS to Huzhou Saiyuan to facilitate the issuance of these convertible bonds.

If the subscribed bonds are not repaid by the maturity date, Huzhou Saiyuan has the right to dispose of the equity interests pledged by the Company in proportion to the amount of matured bonds, or convert the bonds into equity interests of MPS within 60 days after the maturity date. If Huzhou Saiyuan decides to convert the bonds into equity interests of MPS, the equity interests pledged would be released and the convertible bonds would be converted into equity interest of MPS based on an entity value of MPS of $950,000.
