Good afternoon, everyone. I'm James Reinhart, CEO and Co-Founder of ThredUp. Thank you for joining our fourth quarter earnings call. Today, we'll discuss our financial results for the fourth quarter, along with a review of our performance for the full fiscal year 2025. I'll start by reviewing highlights of our first full year back as a streamlined U.S.-focused business and how this focus has allowed us to drive record gross margins and more predictable growth. I'll then discuss our product innovation wins in 2025 and how these investments in our marketplace can translate into compounding advantages in 2026. I will also provide our perspective on the current macro environment, and how we believe our strategy uniquely positions our marketplace model to thrive as consumers continue to look for both value and delight as they allocate their discretionary spending budgets. Finally, I'll turn it over to Sean Sobers, our Chief Financial Officer; to walk through our financial results in detail and provide our initial guidance for Q1 and the full year 2026. We'll conclude the call with a question-and-answer session. First to the results. We're pleased to report that Q4 revenue grew 18.5% year-over-year, while gross margin was 79.6%, and adjusted EBITDA was 3.7% of revenue. In particular, our top line outperformance was driven by our deliberate investments in customer acquisition and new listings. This drove a noticeable surge in both new buyers and customer engagement. To that end, we're pleased to report that new buyer acquisition increased 57% year-over-year, while active buyers for the trailing 12 months were up 30% year-over-year. For the full year 2025, our performance was a testament to the durability and scalability of the infrastructure we've built over the last decade and the fundamental strength of our marketplace model. We delivered record revenue of $310.8 million, representing 20% year-over-year growth, while maintaining our premium gross margin profile at 79.4%. These results were driven by a record 1.7 million active buyers, a 30% increase over the prior year and a record 21.1 million items processed, representing volume growth of more than 17%. Importantly, this operational scale, combined with expense discipline, allowed us to generate $14 million in adjusted EBITDA or 4.4% of revenue. I'm especially proud of the underlying consistency we maintained to achieve this, delivering adjusted EBITDA every single quarter over the past 2 years, and delivering positive free cash flow for the full year in 2025. As I look back on the past 12 months, I'd characterize 2025 as a year where we successfully returned to the core fundamentals of our marketplace and then rapidly built on top of this foundation. This was our first full year operating as a dedicated U.S.-focused enterprise without the complexities of our former European operations. It also marked the completion of our multiyear accounting transition to a fully consignment-based model with more than 90% of our business now on consignment. By removing these historical headwinds and accounting transitions, we've clear the path for the higher-margin scalable growth you see today. I believe this establishes the financial baseline for our business moving forward, predictable growth and exceptional gross margin profile and the operating leverage required to generate consistent free cash flow. In addition, 2025 demonstrated the unique defensible advantages of our marketplace model. During the large tariff disruptions of 2025, we experienced little impact given our supply is wholly on consignment and U.S. sourced. We were able to launch new ways to grow supply, first with premium listings at the beginning of the year, and following up the direct listings at the end of the year. These innovations expand the types of customers we can attract to our business over time. Given our legacy of investments in infrastructure, automation and technology, we rapidly took advantage of emerging AI models to improve product search, discovery, ad buying, recommendations, photography, measurement and flaw detection. I honestly can't remember another time when the business took such giant leaps forward on behalf of the customer. With the surge of innovation across our business, we then executed a well-received rebrand in the fall that better positions ThredUp for years to come as a marketplace for fashion forever. Before we dive deeper into our strategy for 2026, I want to address the broader consumer landscape. I've said for a number of quarters that I think the American consumer may be weaker than headline data would appear to indicate and that recent data validates some of the [indiscernible]. In 2025, job growth was anemic with the DLS revising numbers down by the largest factor in 20 years. At the same time, the New York Fed confirmed that nearly 90% of the 2025 tariff burden fell directly on firms and consumers. This is on top of an affordability crisis where nondiscretionary costs like rents and insurance have structurally reset at higher levels, effectively shrinking the wallet share left over for apparel and other discretionary goods. All this taken together, I think it's fair to say that the macroeconomic environment for discretionary spending remains uncertain, and the American consumers understandably approaching the year with a degree of caution. However, we believe these circumstances allow us to offer a differentiated approach. While traditional apparel retailers may face headwinds in a value-driven environment, our managed marketplace is uniquely built to capture upside demand as consumers prioritize both the stretch of their dollar and the liquidity in their closets. As we enter 2026, our focus of ThredUp is to build on our path towards sustained profitable growth by enhancing the structural drivers of our marketplace flywheel; full-funnel buyer growth, high-quality supply and AI-driven innovation that meaningfully reduces friction in shopping secondhand, all while maintaining our expense discipline. This strategy is threefold. First, we are focused on this full-funnel growth in early life cycle engagement. Our success in 2025 was fueled by record-breaking customer acquisition capped off by a 57% year-over-year surge in new customers during Q4. This momentum proves that our brand and value proposition are resonating at increased scale. As we move into 2026, our priority is evolving from pure acquisition to deepening our relationship with these new cohorts. Our LTV to CAC ratio reached all-time highs in 2025, but we think there is more to do to build multiyear LTV expansion. We recognize that early life cycle engagement is our highest leverage growth driver. By prioritizing retention alongside acquisition, we're building a more predictive, high LTV buyer base that fuels our long-term growth engine. Second, in 2025, we proved that we could scale supply volume meaningfully with kit requests up 36% year-over-year. This wasn't just about quantity. It was about obtaining the right supply, driven by a few key initiatives. A primary driver of this increase can be attributed to our premium kit offering. We launched this product in early 2025 and has scaled into a material contributor to our supply, representing 17% of supply for the year. We will continue to invest in expanding our premium kit offering through new channels as well as evolving the sets of incentives we offer customers. Specifically, we developed a supply approach for capitalizing on the momentum of TikTok shop. While selling unique secondhand SKUs on TikTok shop is challenging, our cleanup kits, premium, regular or otherwise, can be skewed and sold effectively. In January, we sold over 100,000 cleanout bags through TikTok shop with 97% of these orders being brand-new suppliers on our platform. In light of this early success, we are now actively experimenting with TikTok Live and created affiliates to capitalize and convert these new sellers into long-term customers. Our Resell-as-a-Service footprint has expanded to include a handful of beloved brands since our last call, including Lands' End, Steve Madden and Betsy Johnson. We continue to see RaaS as a broad ever extendable platform for adding high-quality supply channels. We are now several months into our direct listing data. I mentioned on our last call that we would be very deliberate in how we rolled out this initiative to meet a market need. Thus, we are focused on growing the business by approximately 10% per week as we observe and learned. There are now thousands of buyers and sellers involved in our beta, providing rich data to test and learn from. Some of the early data has confirmed our hypotheses, while other behaviors have surprised us. Sellers who choose to take advantage of direct listings are listing 10x more items than we expected. This suggests there is enormous closet share left for us to take as we provide more ways for our customers to monetize the full depth of their wardrobes. Sell-through has been as expected. While the average selling price is much, much higher, more than $70, we believe that scaling these higher ASP listings will allow us to further capture a more premium shopper consistent with the launch of our premium kits last year. Customers have also reacted very positively to the seamless nature of using our infrastructure to handle returns, giving them confidence to shop direct listings when they might not have previously done so. We are continuing to roll out new updates to the experience weekly. Most recently, we enabled the bulk import of listings. This way, customers can move their closets over more easily from competitor sites. Already 50% of new listings are now coming from bulk import, which we think is one indicator that we're building the right tools for sellers to consolidate their selling on ThredUp. We launched direct messaging that sellers can communicate and just this week, an offer function, so buyers and sellers can more easily find the market clearing price without ThredUp's direct involvement. Finally, we are leveraging AI to build a structural advantage across our entire business. Our goal is to use technology to remove the friction inherent in resale, both for our customers but also for our bottom line. Following the launch of our AI-powered shopping suite last year, we doubled down with features like the daily edit in the trend report. These tools use proprietary embeddings to move us toward a segment of one where the marketplace feels custom-built for every individual. Looking ahead, we are going to use Agentic AI to transform the ThredUp experience into a much more personalized end-to-end discovery and shopping journey. We are also redefining the post-purchase experience with Dottie, our AI customer service agent. In a relatively short amount of time, Dottie has evolved from a simple question-and-answer tool into an agentic engine capable of facilitating the resolution of customer issues that previously required representatives. By reducing the human escalation rate of customer service inquiries, Dottie allows our team to focus on higher-value interactions and more nuanced customer requests. More importantly, this shift to instant resolution has driven a meaningful increase in our customer satisfaction scores directly supporting our overall customer growth goals. By embedding AI into everything from discovery to service, we are building a marketplace that is not only more enjoyable for the consumer, but structurally more profitable to operate. In closing, as we look ahead, we believe ThredUp is transitioning from a period of recovery to one of compounding progress. The data-driven infrastructure we've built, supported by our commitment to operational excellence and our foundational AI architecture is transforming our marketplace into a more efficient, scalable and personalized ecosystem than ever before. We've often said that marketplaces are hard to build. But when you get the flywheel spinning, they are very hard to stop. By continuing to redefine the buyer experience with emerging AI tools, while expanding our addressable market through supply innovation, we're demonstrating that our model could scale more widely and effectively over time. I'm confident in our team's execution as we work toward our goal of making secondhand, the preferred choice for consumers everywhere and building a generation-defining company that endures. With that, I'll turn it over to Sean to talk through the financials in more detail.
