Auto Parts Stores in the US Industry Data and Analysis
Auto parts stores have endured ups and downs in recent years, similar to the rest of the auto sector. Strong economic gains have boosted auto parts stores, as pent-up demand caused a surge in revenue. Strong consumer activity has driven growth in vehicle miles driven and overall travel. Also, the expanding popularity of electric vehicles (EVs) and other vehicle types has provided opportunities to sell new auto parts. At the same time, stores have contended with the same problems as the wider retail sector, namely higher input prices and supply chain shortages. Auto parts stores weren't able to pass along all price hikes to consumers, resulting in shrinking profitability. Overall, IBISWorld expects revenue for auto parts stores to climb at a CAGR of 0.6 to $75.1 billion through the end of 2026, including a slight jump of 0.9% in 2026 alone.
