Thank you, Nick, and thanks, everyone, for joining us today. I am pleased to report one of the best quarters for Magnite. We significantly exceeded expectations in Q3 across the business, both in CTV and DV+ leading to meaningful top and bottom-line outperformance. We expect this momentum to continue into the fourth quarter and once again are raising both our full year contribution ex-TAC outlook and margin expectations. Total contribution ex-TAC for the third quarter was $201 million and exceeded expectations by over $10 million. CTV beat our expectations by $6 million and grew 39% year-over-year. DV+ also strongly exceeded expectations by $4 million, growing 5%. Political was a big contributor and far exceeded our expectations, coming in at approximately $12 million in Q3 with more than 3/4 of it benefiting the CTV business. We experienced a very strong midterm cycle this year, and Q4 political spend will be even larger than Q3. More on political later in my prepared remarks. Adjusted EBITDA exceeded expectations by $13 million, resulting in a margin of 42%, demonstrating the operating leverage and cost discipline in our business model. CTV performance is broad-based on both the demand and supply side. CTV represented 53% of total contribution ex-TAC in the quarter, continuing the momentum that began over a year ago. The CTV market has reached an important inflection point as programmatic is rapidly becoming the desired way to transact on streaming television. We expect strong growth ahead for programmatic and CTV, and our incredibly strategic role positions us to continue this momentum and drive continued share gains. We remain confident in our ability to outperform the market and expect a long-term 3 to 5 year growth rate in CTV of approximately 25%. We saw strong growth across many of the industry's largest media owners, including Disney and ESPN, Fox and Tubi, LG Ads, Netflix, Roku, Skydance and VZO Walmart. Across our top 10 CTV accounts, growth was once again in the mid-40% range year-over-year with the remaining partners also growing above 30%. We also had a great quarter with new and expanding partnerships. LG Ad Solutions signed a 3 year extension and expansion, deepening our preferred programmatic partnership, extending exclusive ad serving via SpringServe and bringing Agentic buying to the LG TV home screen through our Magnite orchestration layer. We also expanded our Kelly relationship to include programmatic on their home screen units, while HP TV+ selected Magnite as its primary video ad server and programmatic technology partner. And finally, Pinterest announced the global launch of programmatic deals, selecting Magnite as their primary supply side platform. Magnite connects Pinterest display, native and video inventory as well as their high-intent commercial signals directly to major DSPs while integrating Pinterest inventory into Magnite orchestration to enable agentic discovery, packaging and optimization. These partnerships showcase the unique value of our full stack technology and independence. Publishers trust us to manage their most mission-critical advertising infrastructure without the conflict of competing media interest. We are also encouraged by the steady improvement in DV+. Mobile in-app continues to be a primary contributor, growing 17% year-over-year in Q3 and now represents approximately 35% of the DV+ business. We believe the mobile app market will continue to be a solid growth driver for the foreseeable future. As I mentioned earlier, political spend significantly exceeded our expectations. In total, we are now expecting political contribution ex-TAC to be over $40 million for 2026 versus the $15 million previously projected. To put this in perspective, this is more than double the last presidential election and nearly 4x the last midterm cycle. There are three key drivers to our political growth. First, midterm election spending is setting records, and we have the scale and relationships to capture that demand. Second, CTV is coming into maturity and capturing an increasing share of overall budgets. And third, we have dramatically amplified that opportunity through our expanded offerings, including ClearLine and our supply side curation capabilities. Our ClearLine buying tool shortens the path to supply, improving ROI for political advertisers by connecting them directly with the leading media owners in CTV. Approximately 20% of our political ad spend flowed through ClearLine, becoming one of the largest conduits for this demand across our platform. Moreover, our supply-side decisioning capabilities enable customized access to curated supply at scale. These tools allow publishers to segment and price their inventory for political advertisers specifically, improving access, geographic targeting and the consumer experience. Importantly, this technology is powered by deep domain expertise. We've built a dedicated team on the ground in D.C., staffed by political ad veterans with numerous cycles under their belts, enabling us to rapidly respond to urgent campaign needs, support quick launch timelines and capture outsized political budgets. Given our enhanced capabilities in this area, political will increase over 5% of our contribution ex-TAC mix in 2026, up from the 2% to 3% range in previous political years. We believe our success in political is durable based on our unique supply position and tools. And additionally, CTV will continue to play a bigger part of the political spend mix in future cycles. Our strategy is paying off. First, SpringServe has positioned us as the operating system for CTV monetization. Our unique offering serves as a key driver of our market position, allowing us to consistently outpace industry growth rates and expand market share. Second, audience enablement and decisioning are moving toward the supply side, and we believe Magnite is leading that transition. And third, as AI reshapes advertising, it is becoming increasingly clear that our position as a key infrastructure player with a full suite of Agentic tools has publishers and buyers leaning on us to enable these new workflows together with programmatic. Taken together, these trends are fueling our long-term competitive position and growth prospects. Finally, I want to provide a brief update on Google remedies. As you know, the court issued its remedies opinion in September, and we're currently awaiting the final order from Judge Brinkema. While the court and industry are still working through implementation details and timing, we applaud the court's approach in adopting the key behavioral remedies proposed by the DOJ and believe that the ruling will result in more balanced and level playing field with fairer auctions, greater transparency and increased choice for publishers. We're also pleased that the ruling has the potential to open-up additional access to AdWords demand, which has primarily been restricted to the Google Stack. All of these things are very good for our industry and will benefit our DV+ business at some point, hopefully sooner rather than later. In summary, I'm thrilled with our performance this quarter and the momentum that we are carrying into the fourth quarter and 2027. We have strong CTV growth, improving DV+ performance, expanding publisher relationships and the operating leverage to translate that growth into meaningful earnings growth. Before I conclude, I would like to introduce Brian on his first earnings call as our CFO. He's no stranger to Magnite earnings calls and has been an integral part of the team for the last 5-plus years. We are thrilled to have him at the finance helm and keeping us focused on executing at an extremely high level and supported by a great team. Welcome, Brian.
