Motorcar Parts of America (MPAA) Stock Analysis & Winston Score

Motorcar Parts of America makes replacement parts for cars and trucks that are already on the road. Its main products include remanufactured alternators, starters, wheel bearing hubs, and brake calipers — parts that wear out over time and need to be swapped out. The company sells mostly to large auto parts retailers like AutoZone, O'Reilly, and Advance Auto Parts, as well as wholesale distributors. The company makes money by selling these parts to retailers, who then sell them to mechanics and everyday drivers. It operates primarily in North America, with some manufacturing and remanufacturing done in the U.S., Canada, and Mexico. Its competitive position relies on long-term supply contracts with major retail chains, but the negative ROIC and thin margins signal the business is under financial pressure. The key risk is that rising costs and heavy debt could squeeze profitability further, especially if consumer spending on vehicle maintenance slows down.
