Thanks, Nick, and thank you all for joining us today. We delivered exceptional third quarter performance, achieving new company Q3 records across all key metrics. Revenue increased 29% year-over-year and exceeded the midpoint of our guidance range, while contribution ex-TAC increased 27% year-over-year and exceeded the high end of our guidance range. Growth was broad-based across most verticals, driven by strong CTV demand, increased utilization of our proprietary intelligence and the expanded use of Viant AI. Most notably, CTV advertiser spend increased by nearly 40% year-over-year in the quarter, attributable to the unique advantages we deliver for advertisers within this secular growth channel. And finally, adjusted EBITDA increased 24% year-over-year to $19.8 million for the quarter, also exceeding the high end of our guidance range. We experienced ongoing momentum in the quarter with year-over-year contribution ex-TAC growth accelerating for the third consecutive quarter. This success can be directly attributed to our recent evolution into a comprehensive advertising intelligence company. Today, Viant is more differentiated than ever before, equipped to empower advertisers of all sizes through proprietary data, independent measurement, efficient supply paths and advanced AI solutions that work in concert to optimize campaign execution. As our third quarter results indicate, Viant is winning new advertisers while simultaneously capturing incremental budget from existing customers. Our performance is reflective of the strength of our go-to-market offering, which is unlike anything else in the industry. We equip our advertiser clients to win across their respective verticals through a unique arsenal of cutting-edge technologies. When advertisers choose to power their ad spend with Viant, they leverage our intelligence layer, which synthesizes proprietary signals across audience identity, content and attention into real-time actionable insights that optimize ad targeting. They leverage our AI-powered decisioning architecture, Lattice Brain, which operationalizes these insights to dynamically refine and continuously optimize advertising performance. And they leverage our direct access supply path, which connects brands directly to premium publishers, lowering costs and eliminating resellers to maximize working media spend. These innovative solutions represent a vastly differentiated offering, and it is our commitment to innovation that has firmly established Viant as an essential partner for today's outcome-oriented advertisers. Building on that commitment, today, I am excited to announce that we recently closed on our acquisition of Waymark, a generative AI video creative production technology platform built specifically for connected TV. Waymark adds professional-grade creative production capabilities to Viant's expanding suite of services and officially ushers in the era of generative ad creative for CTV. We believe no other buying platform is better equipped to deliver upon this promise. By combining Waymark's generative AI engine with our proprietary intelligence spanning audience, content and attention signals, we plan to empower advertisers of every size to unlock CTV's full potential through audience-tailored, contextually relevant, attention-optimized, creatives produced in minutes and at a small fraction of traditional costs. Waymark's generative AI effortlessly converts brand inputs into complete video ads featuring custom scripts, visuals and voiceovers, enabling Viant to deliver upon the promise of generative ad creative optimization, where endless creative variations are generated to meet any target audience. Together, Viant and Waymark plan to democratize CTV for advertisers of all sizes. Waymark's ability to produce professional-grade CTV-ready creatives in minutes not only accelerates time to market, but virtually eliminates production overhead, removing barriers to entry into the CTV channel and enabling the sheer number of CTV advertisers to scale from thousands to millions. Leveraging Viant's proprietary intelligence, we will empower these advertisers to seamlessly align creative messaging with the target audiences and contextually relevant content to best capture viewer attention. Going a step further, we are uniquely positioned to equip advertisers with a valuable feedback loop where audience engagement and attention metrics are directly utilized to iteratively refine and optimize creatives in an effort to drive maximum performance efficiency. The paradigm is shifting. TV is no longer reserved only for the world's largest brands. We are democratizing CTV as a powerful channel for advertisers of all sizes by removing traditional barriers to entry and equipping advertisers with advanced targeting and measurement capabilities. Looking longer term, Viant is positioning for the future of Connected TV. The era of broadcasting a single static ad to broad audiences is giving way to hyper-relevant targeting, where each creative is tailored to the viewer and the content and is dynamically optimized to maximize attention. With Waymark, Viant empowers advertisers to scale this strategy, delivering not one static ad, but rather hundreds, thousands, potentially even millions of individualized creative variations across audiences to drive peak user engagement and campaign performance. Chris will dive deeper into our technological innovations, including our plans for Waymark, our latest integrations with Frontier models and the launch of the TVision mobile meter. But first, I will provide a brief update on our recent performance and progress across our 3 key strategic priorities: Viant's proprietary intelligence layer, Viant AI and CTV. Beginning with our intelligence layer, Viant empowers advertisers to deploy sophisticated ad strategies through 3 core pillars of proprietary intelligence, spanning identity, content and attention. Using our proprietary data signals, advertisers can identify the specific impressions that will drive performance. Leveraging our intelligence layer, advertisers can precisely target their desired audiences within contextually relevant high attention environments and capture value by acquiring inventory where the intrinsic value exceeds the market price. I will briefly touch on utilization trends across our intelligence layer. Viant's Identity intelligence is powered by Household ID, our patented audience targeting solution that delivers superior addressability for advertisers, activating first-party data. By enabling precise audience targeting at scale, coupled with customized campaign measurement, Household ID continues to set the industry standard for identity resolution. Household ID utilization increased once again in the quarter, driven by favorable secular tailwinds, including the growing need for advertisers to justify ad spend through targetable, measurable campaign strategies, particularly across the proliferating CTV channel. Contribution ex-TAC generated from Household ID utilization reached its highest level ever for a third quarter period, fueled by growing adoption among advertisers looking to deploy the industry's most sophisticated audience targeting strategies. Viant's content intelligence is powered by IRIS Content ID, which delivers show-level content targeting precision and vastly differentiates Viant from competitors limited to app-level visibility. Through direct publisher integrations, we unlock scene-level contextual intelligence, enabling advertisers to align their creative with specific programs, themes and emotional tones, achieving a degree of contextual micro targeting that drives superior campaign results. With a growing number of major CTV publishers becoming IRIS-enabled, advertisers can now fully leverage our contextual targeting solution at scale. And this was evident in our results as surging advertiser utilization drove a 41% year-over-year increase in IRIS-enabled ad spend in the quarter. Viant's attention intelligence is powered by TVision and its nationally representative panel of U.S. households, each of which is equipped with TVision's computer vision and automatic content recognition technology. TVision's attention data provides advertisers with 4 unique signals of attentive insight: in-room presence, co-viewership, second-by-second eyes-on-screen attention and associated viewer demographics. These signals quantify viewer attention across the entire media landscape, including linear TV, connected TV and even walled garden platforms like YouTube and Prime Video. Viant is uniquely capable of leveraging this attention data as a pre-bid signal, empowering advertisers to target inventory based on its attentive value. By comparing the real-time intrinsic value of any impression as determined by its attention score to the prevailing market price, Viant can identify when an impression is mispriced and act accordingly, capturing undervalued impressions for clients while avoiding overvalued impressions. Looking ahead, we expect rapidly growing advertiser utilization of both IRIS Content ID and TVision's attention data to be a significant top line growth driver through 2027 and beyond. Household ID, IRIS Content ID and TVision's attention signal provide advertisers with performance capabilities that distinguish Viant from competitors. To maximize the effectiveness of these proprietary solutions, we feed these insights directly into Viant AI's Lattice Brain decisioning architecture. This takes me to Viant AI and Outcomes, our fully autonomous do-it-for-me ad product designed to capture performance budgets deployed across the open internet. Outcomes rivals walled garden solutions like Google's PMax and Meta's Advantage+ while offering the unique advantage of leveraging Viant's proprietary intelligence across the entire open internet, built to optimize campaign execution around specific advertiser goals. Outcomes now powers performance budgets for over 10% of Viant's advertiser base. Adoption has been particularly strong amongst our largest clients. In fact, every single one of Viant's top 10 advertisers is utilizing Outcomes, allocating on average, 26% of their on-platform ad spend to our performance solution. When looking specifically at the 10 largest users of Outcomes, 37% of their collect -- [ Technical Difficulty]
