Thanks, Steve. Hello, everyone. It was a strong quarter and finish to the year for Reddit. Our unique proposition and core platform improvements continue to drive differentiated growth and positive outcomes for advertisers. Total revenue in Q4 grew 71% year-over-year to $428 million and for the full year, revenue grew 62% year-over-year to $1.3 billion. In Q4, the advertising business grew 60% year-over-year to $395 million driven by broad-based strength across objectives, channels, verticals and geographies. Let me discuss our ad revenue drivers in more detail. Our strategy is to be a multi-objective ad platform. And in Q4, we grew across the funnel. We saw strength in brand advertising, with top-of-the-funnel revenue growing the fastest rate in over 3 years. Mid- and lower-funnel revenue accounted for about 60% of total ad revenue and drove more than half of the year-over-year growth in the quarter. Across channels, our scaled business which includes mid-market and SMB advertisers, continues to be a growth driver as we are activating new advertisers across both the U.S. and EMEA regions and tuning our product set to better address these performance-oriented advertisers. We saw broad growth across verticals, with 10 of our top 15 verticals growing over 50% year-over-year led by finance, retail, auto, pharma, gaming and tech. Across geographies, international ad revenue grew 77% year-over-year, the fastest growth in over 2 years and led by the U.K. and broader EMEA regions. We saw double-digit year-over-year growth in impressions from underlying user growth, personalized ad loads, deeper engagement and improved monetization of the conversation page, while pricing was mostly consistent with the prior year. Average impressions per user increased year-over-year as we benefited from ad placement and brand safety optimization work from prior periods. The ads and comments placement contributed about 3% of impressions in the quarter. We continue to test this new format and expect this could reach up to mid-single digits percentage in the near term. Revenue from the Cyber Five week during the holiday period grew over 60% year-over-year. This was driven by a combination of first-time brands and existing retail customers who increase their spend with us. Now, moving to our ad stack. We continue to focus on, one, driving performance of our ad solutions across objectives; two, improving usability for our advertisers and productivity for our sales force; and three, offering our advertisers Reddit-unique solutions and ad formats. We made meaningful progress against each of these areas in Q4. First, driving performance of our ad solutions. We continue to improve the contextual relevance of ads on the conversation page which drives higher conversion volume and performance revenue. In Q4, we doubled-clicked volume for the fourth consecutive quarter and also doubled conversion volume in the second half of the year versus the first half. We also continued driving CAPI, Conversion API, adoptions with onboarding improvements and new integration partnerships. The share of conversion revenue covered by CAPI tripled in the second half of 2024 versus the prior year. Advertisers see a 25% reduction in cost per action when they adopt CAPI with Pixel compared to Pixel only. Second, improving usability for our advertisers and productivity for our sales force. Over the course of the year, we've launched capabilities across two categories. The first is our Ads Manager where we recently improved our report center to provide advertisers with deeper historical trend, comparative attribution windows and keyword breakdowns to optimize targeting strategy. Next is how we continue to invest in gen AI as a driver of productivity and performance. In 2024, we launched our AI Headline Generator and acquired Memorable AI, both of which are driving more adoption for mid-market and SMB advertisers, enabling dynamic campaign creation and providing more predictive insights into creative performance. We recently launched an LLM-powered ad review system which increases automated ad review by 70% and decreases review time from 30 minutes to 1 minute, enabling advertisers to run campaigns faster while also improving ad quality and safety. We also expanded brand safety measurements to both IAS and DoubleVerify. With the IAS launch in Q4, we tested the solution against more than 500 million impressions in North America and found Reddit to be over 99% brand safe. And third, offering advertisers Reddit-unique solutions and formats. We are developing products that leverage Reddit's community intelligence that can help businesses grow, insights, Reddit Pro Trends and advertising solutions that leverage community signals. As we announced at CES, we began testing Reddit Pro Trends, a tool that helps businesses uncover real-time insights and build an organic presence on Reddit. To date, we've seen thousands of advertisers adopt Reddit Pro and seeing participating companies posting and engaging more on the site within communities. Next, I'll shift to our content licensing business. Reddit's content is a unique source of authentic insights and perspectives that is valuable to our users, advertisers, researchers and our content licensing partners. In Q4, we entered into a partnership with Intercontinental Exchange to develop new data and analytics products for the financial industry. This partnership explores a new market vertical for our content licensing business and connects anonymous conversations on Reddit with Intercontinental Exchange's infrastructure to provide financial customers with insights into market trends and sentiment. More broadly, we remain diligent about who we partner with and we will do so when it's complementary to our business. And we are investing in building our own products around our content, including Reddit Answers and Reddit Pro that reveal the authentic insights and recommendations that are unique to Reddit. Okay, looking ahead, I'm pleased with the progress we are making in building a multi-objective ad platform that enables businesses of all types and sizes to be successful on Reddit. Our opportunity is as big as ever. Reddit covers every topic and interest and we believe every business can find value on Reddit. The ad market feels healthy and we're monitoring events that could impact the broader industry and the evolving EU privacy landscape. I believe we're well positioned heading into 2025 and I'm excited about our road map. In the year ahead, we'll focus on three areas that build on our progress to date. First, delivering more Reddit-unique experiences and communicating value across objectives. This includes bringing more ML optimization to our brand objectives as well as Reddit-unique formats that bring in more contacts and engagement from communities and more product catalog features for shopping. We believe all of this work can augment performance. Second, bringing more automation to our ad stack. We're in the early stages of exploring end-to-end automation across our performance objectives. We believe this can help drive performance and lower the barrier to adoption while enabling us to continue to sustain our high marks in customer service. Third, continuing to grow and diversify our advertiser base. We've made good progress diversifying the business, broadening verticals, having customers use multiple objectives and adding more advertisers, all of which increase the resiliency of our business. We believe there's significant opportunity to bring many more advertisers to Reddit by lead generation efforts like Reddit Pro, partnerships, easier onboarding with features like Dynamic Creation and Campaign Import and then retaining these advertisers with strong performance outcomes. Overall, I'm proud of our progress and excited about the opportunity we have to continue growing our share and driving outcomes for advertisers. Thanks for joining and for your continued support. Now, I'll turn the call over to Drew.
