Thank you, Nick. I'm happy to report results for Q3 that exceeded our topline guidance for total CTV and DV+ contribution ex-TAC, while delivering strong profitability and free cash flow. Our DV+ business performed very well, delivering contribution ex-TAC growth of 12% despite a depressed CPM market. Moreover, in CTV, we continue to grow our market share with ad spend growing over 20% year-over-year, exceeding industry growth estimates. We were pleased with our execution in the quarter as we continue to solidify our position as the leading independent player in CTV. And as product mix shifts stabilize and macro ad spend returns to normal, we believe our CTV contribution ex-TAC growth will, over time, approach our ad spend growth. In this respect, it's important to remember that we are still in the early days of programmatic CTV. Marquee publishers are just now ramping AVOD and their inventory is limited and in high demand by advertisers. With this dynamic, pubs generally refer to sell programmatic deals through their direct sales teams. The good news is they are using our technology to execute those transactions. However, as we've explained previously, the programmatic direct business carries a lower take rate versus when we sell the inventory and layer on more services. We believe that as programmatic CTV scales, buyers will want to purchase the majority of their CTV programmatically, using advanced data targeting with embeddable environments, a process that can't be executed using a direct sales team. This evolution will attract a significantly broader advertiser base, increased ad spend, a more competitive CPM environment, and better ROI and COGS for both buyers and sellers We had some noteworthy customer wins this quarter, announcing that we'd be powering the Disney+ biddable marketplace via Magnite streaming as well as an expansion in our partnership with Paramount advertising. Buyers now have access to all of Paramount's combined streaming offerings, including their IQ program through Magnite. We're also encouraged by the fact that a lot of the growth in our CTV business is being enabled to advance integrations with our ad server SpringServe. As you know, ad serving puts us one step closer to the publisher and creates a stickier relationship. With SpringServe, our platform is more deeply embedded within the client workflow and becomes a central technology in their overall monetization strategy. The stickiness of the software and development we provide in CTV is far different than a typical SSP model. We are clearly growing share, as shown by our ad spend growth above 20%. And this is the result of working with nearly every scale media owner outside of the walled gardens. These clients have continually expanded their relationship with us, both vertically and horizontally. I'll offer two examples. One is a market-leading streamer and media company that started using us in a small part of their US business for workflow and directly sold campaigns. Now, that partner has expanded our services to additional streaming platforms to other countries and now uses us to access biddable programmatic demand through the Magnite SSP. Another example is a market-leading TV OEM that started with us in ad serving. They now use us as their SSP and demand engine as well as a source of incremental revenue to our new CTV Tiles product. This same partner also leverages our audience capabilities to sell and package its first-party data on both its direct properties and through audience extension. These examples are common across our top partners and we have continually shown that as our partners grow their CTV businesses, so do the ways in which they utilize our services. Despite a soft start to Q4, largely driven by macro conditions, we believe we are uniquely positioned to capitalize on the inevitable market turnaround. I'll briefly touch on just a few other things that make me the most excited for 2024. Accelerated supply path optimization with our agency partners, particularly in our curated and often exclusive marketplaces. Consolidated spend on our platform leads to more publisher supply and enhance margins. ClearLine, our recently launched buy-side tool is off to a strong start and with additional features and functionality planned for the coming quarters, we expect continued momentum and adoption. If you recall, ClearLine is built to capture linear TV dollars that aren't currently in the CTV ecosystem, a TAM of enormous proportion. And planned innovation across our audience tools, SpringServe ad server, Magnite streaming, and DV+ platforms. With our CTV platform integration behind us, we can now focus exclusively on new innovative products, supporting our unrivaled omnichannel offering and new and existing customer expansion. Although Magnite works with every publisher across the DV+ and CTV landscape, we have tremendous opportunities to grow our existing business and capture new entrants in fast-growing and dynamic markets like CTV. In summary, there's a lot to be excited about our business, our people, our customers, and our partners. I never felt better about our strategic position and ability to grow long-term. We have made the right investments and it's time to put our heads down, work hard, and deliver. We are in a great position to capture an outsized portion of market growth when it inflects by executing and being the best at what we do. With that, I'll turn the call over to David for more details on financials. David?
