Supply Chain Disruptions: The company relies on a global supply chain, making it vulnerable to disruptions from natural disasters, geopolitical events, trade disputes, or pandemics, which can lead to increased costs or product shortages.

Raw Material Price Volatility: Fluctuations in the cost of key raw materials like aluminum, steel, and copper can significantly impact the company's cost of goods sold and profit margins if these costs cannot be fully passed on to customers.

Customer Concentration Risk: A substantial portion of MPAA's sales may come from a limited number of large aftermarket retailers, making the company highly dependent on the continued business and financial health of these key customers.
