Business Description

Overview CarParts.com, Inc. is a technology-enabled eCommerce company dedicated to simplifying how drivers and professional customers shop for aftermarket automotive parts and accessories. With over 30 years of operating history, CarParts.com serves as a one-stop destination for vehicle repair, upgrade, and maintenance needs, delivering a seamless digital shopping experience guided by its mission of “Empowering Drivers Along Their Journey.” We sell aftermarket automotive products to individual consumers and business customers through our owned digital channels, including our flagship website, www.carparts.com , our mobile app, and our wholesale platform, as well as through select third-party online marketplaces, including eBay and Amazon. Our easy-to-use, mobile-friendly website and mobile app provide customers with access to more than 1.5 million products. CarParts.com also supports professional customers through its wholesale platform, www.carpartswholesale.com, which is designed to meet the needs of repair shops and installers. CarParts.com was incorporated in California in 1995 as an aftermarket automotive parts distributor under the name U.S. Auto Parts Network, Inc. In July 2020, we rebranded as CarParts.com and consolidated its web presence into a single eCommerce destination. In the third quarter of 2023, we launched its mobile app on both iOS and Android, enabling customers to shop conveniently from their phones. We continue to invest in modern technology, data, and design to power its digital platforms and improve ease of use across channels. In the fall of 2025, we launched Spark, our AI-powered shopping assistant, designed to help customers more easily discover products, navigate fitment, and complete purchases with greater confidence. We believe that we have a significant opportunity to become a preferred destination for automotive repair and maintenance by executing on our evolving strategy, which includes investing in technology, expanding product offerings and customer segments, and enhancing supply chain and logistics capabilities. ​ To support this strategy, we continue to enhance our fulfillment center footprint and productivity. In June 2024, we opened a new state-of-the-art fulfillment center in Las Vegas, Nevada. This semi-automated facility is designed to improve service levels, support faster delivery to the West Coast, reduce last-mile transportation costs, and expand product availability. With this expansion, we operate four distribution centers across the U.S., totaling over 1 million square feet of fulfillment space. ​ In tandem, we have refined our eCommerce experience and segmentation strategy to prioritize direct customer relationships and long-term engagement. In 2010, we acquired the JC Whitney brand. In 2025, we launched the JC Whitney Performance Hub, featuring branded performance and upgrade products. We are also expanding our assortment in the European vehicle segment, having launched the CarParts Euro hub in early 2025. These initiatives are intended to strengthen brand loyalty, increase customer lifetime value, while positioning CarParts.com as a trusted destination for automotive parts and maintenance support. ​ In September 2025, we secured a strategic investment from ZongTeng Group, A-Premium, and CDH Investments to support an expanded mechanical and performance parts assortment, enhanced fulfillment capabilities, and continued operational improvements. We remain focused on disciplined growth and believe we are well positioned to execute on our long-term strategy in the automotive aftermarket. ​ Our corporate website is located at www.carparts.com/investor .
