Thanks, Bill, and good afternoon, everyone. Today, I'll be discussing our third quarter 2025 financial results and provide an update on our preliminary fourth quarter 2025 outlook. All financial metrics, except for revenue, will be discussed in non-GAAP terms unless otherwise specified, and all comparisons will be discussed on a year-over-year basis unless otherwise noted. Now let's start with our third quarter results. We ended the quarter with 600 million global monthly active users, or MAUs, growing 12%, our ninth consecutive quarter of record high users. We continue to demonstrate user growth across all of our geographic regions. In Q3, our U.S. and Canada region had 103 million MAUs growing 4%, our Europe region had 150 million MAUs growing 8%, and then the Rest of World markets, we had 347 million MAUs growing 16%. Shifting to revenue. In Q3, our global revenue was $1.049 billion, up 17% on a reported basis and 16% on a constant currency basis. We saw strength across our conversion and awareness objectives. Across verticals, we continue to see strength led by retail as well as by smaller, faster-growing categories on our platform, including telecom and entertainment. We also continue to see a normalization within CPG, driven largely by our food and beverage subvertical. Turning to our geographical breakouts for Q3. In the U.S. and Canada, we generated $786 million in revenue, growing 9%. Strength came from retail, CPG, Telecom and entertainment. In Europe, revenue was $193 million, growing 41% on a reported basis or 34% on a constant currency basis. Strength in Europe was driven by retail. Revenue from Rest of World was $70 million, growing 66% on a reported basis or 65% on a constant currency basis. We're pleased to deliver the strong 17% third quarter revenue growth which exemplifies our multiple ways to win that I've spoken about for many quarters. We continue to diversify our business across geographies, grow long-standing as well as new advertiser verticals and begin to deepen our share with mid-market and smaller advertisers. We did face pockets of moderating ad spend in UCAN in Q3 as larger U.S. retailers navigate tariff-related margin pressure in the current environment. However, as Bill noted, we also saw accelerating strength across our international geographies in Q3 as we have begun to successfully export our lower funnel playbook around shopping. In Q3, overall ad impressions grew 54% while ad pricing declined 24% year-over-year. The primary driver of the continued strong growth in ad impressions and corresponding decline in ad pricing continues to be the growing mix shift from ad impressions in previously unmonetized or undermonetized international markets, which carry lower ad pricing than our more mature markets. Moving to expenses. In Q3, cost of revenue was $206 million, up 13% year-over-year and up 5% versus Q2 due to increased infrastructure spend related to our user and engagement growth. Our non-GAAP operating expense was $543 million, up 15%. The increase was due to investments in sales and marketing and R&D as we continue to invest in headcount to support our AI and other product initiatives as well as our sales force. Our revenue growth, combined with our disciplined approach to cost led to another strong quarter of adjusted EBITDA coming in at $306 million, a margin of 29%. Adjusted EBITDA margin expanded 170 basis points versus Q3 last year and helped to deliver Q3 free cash flow of $318 million. This speaks to the inherent profitability of our business and highly cash-generative nature of our model with over 90% of our adjusted EBITDA converting to free cash flow over the trailing 12 months. We ended the quarter with cash, cash equivalents and marketable securities of $2.7 billion. As a reminder, we've previously discussed the 4 pillars of our capital allocation framework, which remain unchanged. First, investing in product and technology innovation; second, balance sheet optimization; third, preserving flexibility for opportunistic and disciplined M&A; and fourth, dilution management. To that end, as part of our ongoing efforts to mitigate dilution from employee stock-based compensation, in Q3, we allocated $199 million towards share repurchases and $115 million toward net share settlement of equity awards, thus bringing fully diluted share count roughly flat year-over-year. Now I'll discuss our preliminary guidance for the fourth quarter. We expect Q4 revenue to be in the range of $1.313 billion to $1.338 billion, representing 14% to 16% growth year-over-year. Our guidance assumes the impact of foreign exchange to be approximately 1 point of tailwind based on current spot rates. Moving down the P&L. We expect Q4 2025 adjusted EBITDA to be in the range of $533 million to $558 million. We anticipate Q4 2025 non-GAAP cost of revenue to grow sequentially from Q3 2025 by high single-digits percent. Within Q4 non-GAAP operating expense, our primary area of investment will continue to be headcount growth within R&D to support our efforts in AI and other product initiatives as well as our global sales team. Our Q4 adjusted EBITDA guidance confirms that we will continue to expect adjusted EBITDA margin expansion in the second half of 2025. Consistent with our commentary on our last earnings call, the level of expansion in the second half will be lower than the more elevated expansion we delivered in the first half of 2025 as we continue to invest in revenue-driving initiatives. Overall, we are pleased with our progress in 2025 towards our long-term adjusted EBITDA margin targets and our ability to continue generating significant free cash flow. In closing, I'm proud of our team for another strong quarter as we continue to deliver for our users and advertisers. With that, I'll hand it over to Bill for some final words.
