General Motors has established a $4.5 billion framework to secure inventory of critical components, including semiconductors, through inventory management firm Procura Auto Parts while preserving its own cash. The arrangement, disclosed in an SEC filing on the 11th, allows Procura to purchase parts from GM's key suppliers and advance payment on GM's behalf. GM prepays interest and fees to Procura and pays for the parts when they are needed, while the inventory remains stored at supplier facilities. The structure is intended to strengthen supply-chain resilience without requiring GM to hold the inventory on its own balance sheet or tie up large amounts of working capital. The move reflects lessons from the COVID-19 era, when factory shutdowns, logistics bottlenecks and semiconductor shortages disrupted automakers globally, and comes as companies adapt to broader risks including extreme weather, natural disasters and cyberattacks. GM did not specify which parts or suppliers are covered, but said semiconductors are among the critical components.
