Thank you, Nick. We are pleased to deliver another strong quarter of CTV growth and a strong beat on adjusted EBITDA allowing us to boost full year numbers. For the quarter, our year-over-year growth rate and contribution ex-TAC from CTV accelerated to 23% from a 12% growth rate in Q2. Strong CTV performance was driven by overall ad spend growth, increasing programmatic adoption by the industry's largest players, ad serving strength, and solid contribution from political. Our growth rates in contribution ex-TAC from CTV and ad spend have significantly narrowed showing a stabilization in our mix and corresponding take rate. Robust programmatic CTV adoption is also continuing across a broad set of partners. As volumes continue to scale and CPM pressures persist, our clients are increasingly looking for us to help them add value to their inventory by layering on data to target and segment audiences. It is critically important for these partners to utilize programmatic selling to reach all demand sources including SMB advertisers that didn't historically play in linear. We believe these trends are very powerful in expanding industry usage of programmatic and growing our accessible TAM. Partners more fully embracing programmatic include Roku, Netflix, Paramount, Warner Discovery, and Disney. Next, I want to highlight our Netflix and Disney partnerships. Netflix's rollout of Magnite powered programmatic solutions continues to ramp and we anticipate the partnership to grow in revenue contribution through 2025. We recently announced a two-year extension and expansion of our relationship with Disney. The recently signed deal now expands our partnership to include live sports like college football, the Latin American region, and podcast for ESPN and ABC News. We will also make Disney inventory available through ClearLine. Magnite will continue to be a key partner for Disney in the years to come and we are pleased to further broaden our partnership. We are also seeing a nice boost from live sports this summer and fall. Recent areas of growth are college football, NFL from the top MVPDs, and Olympics internationally. This is a market that is beginning its journey to programmatic. In our industry-leading tech offering combined with our scale to monetize real time inventory is unmatched. We expect growth in live TV and live sports to continue with more sports and more partners in the coming years. This is a key investment focus for the company. We are optimistic about the commerce media vehicle being a powerful long-term growth driver and I'm working many new opportunities in this space. Our partnership with United Airlines announced this summer is progressing well. We are now powering ad serving on personal devices on hundreds of planes and look forward to expanding beyond personal device entertainment to include seatback screens in 2025. ClearLine, our self-service direct buying platform is continuing to grow and gain traction. We now have more than 20 agencies and brands buying through ClearLine and continue to ramp their efforts. I want to double click on our CTV ad serving business, which has been operating at nearly twice the ad impression volume from a year ago. Our software is deeply embedded within our partner workflows and go-to-market solutions as a core part of their operations, comparable to enterprise software solutions. It's very sticky and allows us to provide superior overall monetization. Our market leadership position in CTV continues to get stronger and we remain extremely focused on innovative features and services that will extend our lead into the future. Evidence of this is our deep and evolving partnerships with the likes of Netflix, Disney, Roku, Warner Brothers Discovery, Paramount, Fox, Samsung, LG and Vizio. The fastest growing account this quarter included Roku, Warner Brothers Discovery, Disney and LG. A solid portion of this growth comes from our SpringServe and Magnite streaming SSP combination, which gives us a competitive advantage as a programmatic first partner and is a major differentiator. Now to DV+, Q3 once again finished in line with our expectations with contribution ex-TAC growth of 5%. Contributing to growth are investments in emerging formats such as native, audio, podcasts and digital out-of-home. Our volume of ad requests continues to grow and we continue to get much more efficient with our cost per ad request coming down by approximately 30% versus last year. Our improving efficiency is driven by filtering, traffic shaping and AI. Another tailwind aiding our DV+ and CTV businesses is the increased importance of sell-side audience aggregation, a practice that is commonly referred to as curation. In simple terms, curation is the selective packaging of ad inventory using audience data to help advertisers reach audiences they might otherwise miss. For sellers, it means driving substantially higher yields on impressions that might have gone unsold. As Ad Age recently noted, there's an ongoing industry shift toward curation on the sell-side, and it's being fueled in part by signal loss on the demand side, where data collection is becoming more restricted due to privacy changes in browsers and devices. We'd add to this that within the sell-side there's no better home for curation than the SSP, where it's easiest for premium publishers to ally with their peers to attract spend they'd have a harder time getting individually. In fact, Magnite's revenue from curating publisher audiences has grown over 100% year-over-year. Its early days, and we anticipate this growth to continue for the foreseeable future, given our strong tool set and unrivaled publisher footprint. Just last week a Forrester report evaluating 10 SSPs highlighted curation as one of the top three capabilities publishers should prioritize to drive higher yields and differentiate themselves. Not only did Magnite receive the highest possible score for curation, but I'm proud to say, we also achieved the highest overall score for the totality of our current offering. Expanding our leadership in curation is critical and is another example of how our omni-channel footprint will enable capabilities for both CTV and DV+ that no one else has and will drive outsized market share gains. In closing, we delivered strong Q3 results and Q4 guide. The strategic investments we've made to create the world's leading programmatic CTV platform are clearly paying off. We are confident about a strong finish to the year. It's an exciting time for the role of programmatic in the evolution of CTV advertising. And as the industry scales and this evolves to bring in thousands of new buyers, we are also optimistic about 2025, as programmatic continues to gain steam at CTV, we ramp up new and existing partners and see continued acceleration in sports and further growth of ClearLine. With that, I'll turn the call over to David for more detail on the financials. David?
