Thanks, Brinlea, and good afternoon, everyone. Let me start today's call with a quick take on the most recent quarter. In Q4, we delivered a strong 38% adjusted EBITDA margin and 8% year-over-year growth in revenue, demonstrating the strength of our operating model even as revenue came in below expectations. As we mentioned last quarter, while we anticipated some retail softness, our results were impacted by further pullbacks of a customer campaign spend late in the quarter, primarily due to agency-related changes. We saw no broad-based spend decreases or detachment of DV services and noted exceptional strength across multiple sectors in the fourth quarter, including health care and technology. We reported strong customer retention during the quarter with no new deactivations among our Top 100 customers in Q4 and usage across social and streaming TV continues to scale. In addition, our Programmatic business continued to grow, with nearly 2/3 of the impressions that we engage with delivered on mobile, in-app and mobile web environments. Outside of mobile, both programmatic display and video measurement impressions grew at double-digit rates in 2025. The investments we are making in building durable, diversified long-term growth in sectors that continue to thrive alongside the AI revolution, namely social, streaming and AI platforms are becoming core catalyst for our future growth. Social activation accelerated meaningfully growing at approximately 60% year-over-year in Q4 and starting 2026 at an even stronger year-over-year growth rate. And Authentic AdVantage on YouTube is entering the year with $8 million of expected ACV. CTV measurement impression volumes also grew impressively, up 22% for the quarter continuing their cadence of outsized growth. We also saw strong interest in our ABS enabled Do-Not-Air-Lists for Streaming TV, which entered general availability with a strong debut this January with 3 top 15 customers, representing hundreds of millions in CTV spend implementing prebid controls. AI measurement tools like SlopStopper and Agent ID showed meaningful engagement rates and are now being tested by 6 of our largest customers with a broader rollout scheduled for the coming months. Together, the areas which are most important for a durable growth story in the future are setting us up for a strong 2026. Before turning to the full year 2025 results, I want to discuss the continuing evolution of our product-led growth cycle and what is really on everyone's mind, our take on the potential impact of AI on advertising and DV's business. DV's growth cycle and trajectory is foundationally shaped by the timing of product releases, platform enablement and customer adoption. Over the last year, our new product development cycle accelerated across social, CTV and AI platforms with several major releases rolling out in the fourth quarter of 2025. With Social and CTV innovation now broadly available and AI capabilities continue to expand, we've entered 2026 with a more diversified revenue mix driven by a broader product offering. These new solutions fuel 2 main product-led growth engines. First, we have a significant opportunity to expand within our existing customer base. As we elevate product attach rates for our new Social, CTV and AI Platform Verification capabilities, we drive higher wallet share, spur revenue growth and create broader, stickier client relationships as enterprise customers adopt more of our platform. As a result, average revenue per top 100 customers grew by 7% for the year to $4.5 million. Second, our accelerating product cycle is enabling us to win new customers and gain market share with proprietary solutions as entry points to new customer engagements. Our leadership in the fastest-growing areas of digital advertising, Social, CTV and AI-enabled performance optimization is expanding our relevance, increasing our competitiveness and landing us new logos. These differentiated solutions drove a 90% greenfield win ratio in Q4, our highest ever recorded meaning that we are winning deals with solutions in new areas in which there are no competitive incumbents to displace. Ultimately, our product innovation in 2025 harnessed the power of AI to expand TAM, improved solution efficacy and drove stronger margins and also helped deliver solid results that will set the stage for future growth. We grew total full year revenue 14% year-over-year, well exceeding the 10% growth outlook we provided at the start of the year. We also delivered double-digit growth across all 3 revenue lines. We continue to onboard large global enterprise customers, further strengthening our position as a trusted partner to the world's leading brands. This momentum delivered strong profitability and cash generation with a 33% adjusted full year EBITDA margin and $211 million in net cash from operating activities. Now turning to the impact of AI on marketer behavior and more importantly, for this call on DV's business. To put it simply, we see this evolution only in terms of accretive future opportunities for DV. The ad ecosystem has always been one in constant flux, where marketers buy ads, how they buy ads and even how they create those ads changes with each advancement of media and technology. The current AI revolution is just the next evolution of this story. And all of these evolutionary cycles, what has never changed is why marketers buy ads, their need for measurement and their demand for trust and transparency. Whether it was ad networks in 2010, programmatic platforms in 2018, social networks in 2021 or agent-based AI platform buying in 2026 and beyond, DV has been and will be essential in driving transparency and trust. Regardless of changes in media or mode of buying, our customer value proposition lies in the vast amount of data we gather and the trust layer that supports the unbiased independent analytics we provide. In the AI era, the question isn't about who has the best model. It's about who has the best data. DV generates a massive proprietary data set from the hundreds of terabytes of advertising data we process every day across trillions of annual transactions. This isn't generic web data that anyone can access or scrape. These are proprietary signals tied to actual ad delivery, brand suitability, fraud detection and business outcomes based on contracted relationships with leading platforms. LLMs can help us interpret this data faster and more efficiently, but they cannot replace its unique value. DV has never been about the media or the method, but about the data supporting the motive. In addition, OpenAI's introduction of advertising marks the creation of an entirely new digital media environment, and DV is ready for this evolution. According to e-Marketer, ad spend on LLMs is expected to grow to over $25 billion by 2029, cannibalizing over 14% of search spend, which is a $400 billion market that DV has historically not been able to access. We believe advertising within LLM platforms has the potential to create a new search like digital channel where independent verification from companies like DV becomes foundational. Independent metrics in this new environment are critical and several dozen of our current customers who are experimenting in this new space have already indicated that they expect consistent measurement across everywhere they advertise. While AI platform ad models continue to evolve, advertiser demands remain the same, ensuring ad transactions are trusted and transparent and adds are reviewable, brand suitable and delivered to legitimate traffic within authentic content environments. As digital advertising becomes more automated, agentic and opaque, as AI slop becomes the must-avoid content category for advertisers, the need for independent verification, protection and performance measurement has never been greater. Regardless of platform, buying mode or message, DV will be an integral trusted part of this ad equation. Building on our progress in product innovation in 2025, I'll now walk through the updates on our key 3 product cycles. Starting with Social, Streaming TV and closing with AI. As noted on previous calls, our goal is to increase the contribution of social streaming and AI-driven solutions from under 30% of total revenue today to approximately 50%, creating a revenue mix that more closely aligns with global digital ad spend trends. Starting with Social, it remains our fastest-growing environment and a core driver of our next phase of growth. As I mentioned earlier, Social Activation accelerated meaningfully to approximately 60% year-over-year growth in the fourth quarter, up from around 20% growth in Q3. That acceleration was driven by continued scaling of Social Prebid, building upon Meta's specific product enhancements that we upgraded through the year. Expanded content level avoidance across feed and reels nearly doubled filtering coverage and materially improved activation effectiveness. By year-end, 68 advertisers were live on Meta activation, up from 56 in the third quarter. Adoption is being driven by large enterprise advertisers, with 28 coming from our top 100 clients. We exited December with Social Activation at an annualized run rate of approximately $8 million, ahead of our expectations, and it continues to be our fastest-growing area as we start 2026. Adoption of DV Authentic AdVantage on YouTube also expanded during the quarter with estimated ACV of approximately $8 million driven by continued customer adoption. Some of our largest CPG customers has started scaling on the solution, and we are excited about the opportunity to grow this business over the coming quarters. Also driving social growth into 2026, we expanded attention measurement on TikTok during the fourth quarter, becoming the platform's first badged marketing partner to deliver impression-level attention insights. In addition, we expanded our post-bid brand suitability measure on Meta to include Facebook Reel Overlay placements, extending independent transparency across one of the platform's fastest-growing ad formats. Finally, we expanded our integration with Meta through the launch of Rockerbox Relay, which enables Rockerbox customers to send attribution results to Meta as an optimization signal. This launch improves advertisers' ability to drive performance against outcomes. Turning to Streaming TV. 2025 marked an important inflection point in our expanding CTV strategy. Over the course of the year, we launched a series of products to address growing advertiser transparency demands and increasing fraud in streaming environments, including verified Streaming TV measurement and pre-bid controls, automated Do-Not-Air workflows, and enriched program level intelligence through our licensing of IMDb data. We've already begun to see solid early adoption of ABS Do-Not-Air Lists from our largest advertisers as well as strong interest in our Authentic Streaming TV solution, which we launched at CES in January. Expanding our growing CTV footprint, we launched our integration with LinkedIn to deliver measurement for CTV impressions. This expansion extends DV's independent verification and authentication to LinkedIn CTV ads across existing streaming environments, increasing measured CTV coverage and reinforcing DV's leadership in transparent cross-channel media measurement. Together, these innovations helped grow CTV measurement volumes by 33% in full year 2025, reflecting continued advertiser demand for independent transparency in streaming environments. As mentioned previously, the tools that we launched in 2025 to combat the increasing challenge of navigating AI slop are gaining traction with our largest customers. This momentum will be bolstered in the first half of 2026 with the launch of DV SlopStopper for Social, a premium solution to address a content arena rife with issues that advertisers are eager to avoid on platforms that attract the lion's share of advertiser spend. 2025 was a year of product development acceleration, partner expansion, meaningful growth across all of our business lines and continued strong margins and cash flow. Before turning it over to Nicola, I want to briefly address capital allocation. Returning capital to shareholders is a core element of our long-term value creation strategy. And as of today, we have $300 million authorized for share repurchases, the largest amount in DV's history, which we plan to actively deploy in 2026 at increased levels versus prior years. This reflects our confidence in our business, the continued strength of our balance sheet and our commitment to creating long-term shareholder value. With that, let me turn the call over to Nicola.
