Thank you, Nick. We are pleased to post another solid quarter with revenue of $37.6 million, reflecting year-over-year revenue growth of 27%. Importantly, our bottom line came in very strong, showing the leverage we have in our business model. We delivered $6.1 million of adjusted EBITDA carrying a 16% margin. We continue to perform very well during the time of industry consolidation and feel very good about our position with buyers and sellers, especially as we've realized the first, albeit small, revenue from Demand Manager in the fourth quarter. Stepping back from Q3 specific performance, I wanted to give some context and perspective and industry trends that have influenced several of our strategic moves. Our first strategic objective when I started at Rubicon was to build our position in header bidding and regain our independent market-leading position. Header bidding caused an explosion in ad requests over the past few years and we're focused on ingesting as many impressions as possible to really understand the new market dynamics of header. This large volume of ad requests required a significant amount of CapEx in cloud investment for both us and our DSP partners. Our first move to optimize this inventory of scale was buying nToggle for their traffic shaping technologies and industry leadership on the demand side. We have now reached the stage that allows us to refine unit economics and to focus to a greater degree on profitability, along with our focus on revenue growth. This takes the form of filtering, prioritizing, removing and eliminating various impressions and creating further efficiencies in the large volumes of internal data flows. The results of our efforts in this phase have more significantly manifested themselves in our financial performance this quarter. This also completely aligns with buyers and sellers priorities of getting the most streamlined and efficient supply possible, and have more ad dollars flow to working media. This allows us to sharpen our focus on mobile, audio, video and Demand Manager. Back to current revenue trends. As was the case in Q2, in Q3, was saw some monthly revenue variability during the quarter. Q3 started strong, followed by some volatility, which included: first, Google's move to a first-price unified auction structure that included Google's removal of last look advantage, which had historically hurt win rates of others. From what we've observed, thus far, after initial period of volatility, the net results have been neutral to slightly positive. Second, our implementation of app-ads.txt and sellers.json later in the quarter, which are industry initiatives that highlight transparency in the supply chain. The impact of these has slightly reduced top line revenue. And lastly, implementation of efficiency and profitability initiatives and network optimization through expanded traffic shaping, filtering and low-value inventory scrubbing was slightly negative to revenue, but improved bottom line flow through. I'd like to focus on network benefits realizing Q3 that resulted from a number of initiatives and allowed us to operate with a more efficient cost base even as our ad request doubled on a year-over-year basis. 2 key efficiency drivers came together this quarter. First was greater benefit from deploying our traffic shaping and filtering technology into the software layer vertex deck. Previously, we had deployed filtering and traffic shaping with a more costly hardware-based solution. The software layer development allowed for removal of servers in our exchange, a reduction in related data center cost and allowed us to remove non-monetizing impressions and reduce network load. A second network optimization move made in Q3 was removing inventory that either did not monetize or monetize at very low CPMs or filled rates that were not profitable. On all fronts, the nToggle acquisition has greatly exceeded expectations. From the financial benefits of lowering our annual CapEx spending from $40 million back in 2017 to $20 million each of the last 2 years to lowering our network operating expenses to the leadership who are the foundation of our buyer-sales team, we've benefited across the board. Given the strong financial performance we had in Q3, we believe we are on track to deliver our long-term targeted adjusted EBITDA margins of 25% or higher. Let's turn to our growth drivers. Our long-term growth drivers remain unchanged, supply path optimization, video and Demand Manager. We continue to see supply path optimization, or SPO attention with the agencies, brands and DSPs with a typical seasonal pause related to annual code freeze in Q4. Video continues to be a driver of our revenue growth. The rate of growth in Q2, Q3 was in line with industry growth rates and the opportunity for CTV remains very promising for the long term. We are very pleased with the high customer interest and our continued customer pipeline progression for Demand Manager, which has now begun initial revenue generation. We are also excited to have announced the purchase of RTK.io, a leader in the emerging space of Prebid tools. RTK provides Prebid tools in services that brings simplicity and control to header bidding for publishers and the acquisition ad some of the world's top Prebid experts and developers to our already great team. The RTK customer base is highly complementary to our existing pipeline and we'll add to our early revenue generation. We are thrilled to double down on this growth opportunity for the future. Our plan is to merge both products in the coming months in a best-of-breed combination that further distances us from any competitive offerings. We are very pleased with our Demand Manager customer engagement with the additions of Business Insider, LA Times and Everyday Health among others to those previously announced back in May. Revenue from our Prebid tools business will be more predictable than our auction business since it's based on a much larger ad spend base from our publishers as opposed to just the portion of their ad spends that runs through our exchange. It will also be stickier, and we anticipate we'll build steadily similar to a service-based software model. It will also carry strong incremental margins, continuing to add to the financial leverage in our business. We are very pleased to be adding the service revenue toward overall revenue base for the long-term. As you are aware, a Demand Manager solution is built on Prebid, the open source standard that's used by hundreds of the world's largest sellers and respected across the ecosystem for transparency and flexibility. Prebid continues to gain greater publisher support with each passing month and a number of publishers and developers adding code now numbers in the hundreds and has critical mass. We will share more customer and financial details about Demand Manager and the addition of RTK on our Q4 call, as previously indicated. Our journey to recovery started with growing ads spent and amounts paid to sellers back in 2017 and 2018. We then moved to growing revenue in 2018 and 2019, crossing over to positive adjusted EBITDA late last year and this year. For the full year 2019, inclusive of our Q4 guidance, which David will discuss shortly, we expect to post year-over-year revenue growth of approximately 25% with adjusted EBITDA margins in the mid-teens and positive cash flow for the full year. While we still have much work to do, we are pleased with top line growth and even more so with the bottom line performance this past quarter. Our market position and growth drivers, combined with the powerful leverage we have in our business model puts us in a great position to grow, invest in the business and delivering improved profitability going forward. With that, I will hand things over to David who will go into greater detail regarding our Q3 financial performance.
