… also makes us a better partner. As more of our competitors prioritize their own owned and operated inventory, our independence becomes even more valuable to advertisers, publishers, retailers, and technology partners alike in the long term. That's one of the reasons why our partnerships continue to deepen. Today, we work with many of the world's leading media companies, including Disney, Netflix, NBC Universal, Fox, Paramount, Spotify, and News Corp. We also partner with the infrastructure of the open internet through companies like Snowflake, Databricks, LiveRamp and Hightouch, helping brands activate their data wherever it creates the most value.

The campaign used retail data from Tesco, Sainsbury's, and Ocado, as well as in-flight COA AI optimizations, predictive clearing, and cross-device targeting. Over four months, the campaign drove a 5x uplift in sales, a 92% lower CPM compared with the benchmark, and a 2x ROAS improvement versus without using retail data. This is a great example of a leading global brand embracing AI and decisioning to drive more outcomes for their business. When I think about everything that we've discussed today, that's ultimately what gives me confidence. The market opportunity is expanding. Our competitive advantages are becoming more relevant. Our …
