Power Solutions International, Inc. (Nasdaq: PSIX) amended its long-standing supply agreement with HD Construction Equipment Co., Ltd. (HCE), an affiliate of HD Hyundai, establishing multi-year engine supply commitments. The agreement represents HD Hyundai Construction Equipment's second major supply contract in North America's power-generation engine market within a month, as AI data centers increase demand for on-site generation. The arrangement is intended to improve supply-chain visibility, secure long-lead engine capacity and support PSI's growth in stationary natural gas power systems for data centers and other critical infrastructure. PSI integrates engine long blocks, or partially assembled engine cores, into its power systems and said the agreement provides price certainty and an agreed delivery schedule as customer demand increases. The relationship with HCE and its predecessors dates to 2007 and forms part of PSI's Power Boost 2030 strategy. The company cautioned that its outlook is subject to risks including HCE's delivery performance, customer demand and order conversion, advance payments, a possible 2029 price increase if purchases fall below 90% of scheduled volume, supply-chain disruptions, energy-market volatility, tariffs and trade restrictions, and other risks in its SEC filings.
