Business Description

ThredUp operates one of the world’s largest online resale platforms for apparel, shoes and accessories. Our mission is to inspire the world to think secondhand first. We believe in a sustainable fashion future and we are proud that our business model creates a positive impact to the benefit of our buyers, sellers, clients, employees, investors and the environment. Our custom-built operating platform consists of distributed processing infrastructure, proprietary software and systems and data science expertise. This platform is powering the rapidly emerging resale economy, one of the fastest growing sectors in retail, according to GlobalData's assessment of the secondhand market in January 2025. ThredUp’s proprietary operating platform is the foundation for our managed marketplace, where we have bridged online and offline technology to make the buying and selling of tens of millions of unique items easy and fun. The marketplaces we have built enable buyers in the United States (“U.S.”) to browse and purchase resale items for primarily apparel, shoes and accessories across a wide range of price points. Buyers love shopping value, premium and luxury brands all in one place, at up to 90% off estimated retail price. Sellers enjoy ThredUp because we make it easy to clean out their closets and unlock value for themselves or for the charity of their choice while doing good for the planet. ThredUp’s sellers order a Clean Out Bag, fill and return it to us using our prepaid label. We take it from there and do the work to make those accepted items available for resale. In addition to our core marketplace, some of the world’s leading brands and retailers are already taking advantage of our Resale-as-a-Service (“RaaS”) offering, which allows them to conveniently offer a scalable closet clean out service and/or resale shop to their customers. We believe RaaS will accelerate the growth of this emerging category and supplements our overall supply strategy. We have built a differentiated and defensible operating platform to enable resale at scale, combining: • Distributed Processing Infrastructure. Our infrastructure is purpose-built for “single SKU” logistics, meaning that the vast majority of items processed are unique, came from or belong to an individual seller and is individually tracked using its own stock keeping unit (“SKU”). As of December 31, 2025, we operated distribution centers that could collectively hold more than7.5 million items.
