Thanks, Bill, and good afternoon, everyone. Today, I'll be discussing our third quarter financial results and provide an update on our preliminary fourth quarter 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. To echo Bill's sentiment, I am proud of our team's execution, which resulted in a great quarter, marked by strong monthly active user growth, continued revenue acceleration and significant year-over-year adjusted EBITDA margin expansion. It is clear that the strategic shifts we have implemented in our business over the last year leaning into the differentiators of our platform and accelerating our ads product velocity are resonating with users and advertisers alike. We ended the quarter with 482 million global monthly active users, growing 8% and reaching a new all-time high. Our investments in increasing shopability and deploying AI across our recommendation engine are paying off. In the U.S. and Canada, we had 96 million monthly active users, up 1% year-over-year and we added approximately 1 million users versus last quarter. In Europe, we finished the quarter with 128 million monthly active users, up 7%, an acceleration from last quarter. In our rest of world markets, monthly active users were 258 million, up 12%, continuing the trend of acceleration throughout 2023. Now to revenue. The strength we saw this quarter further demonstrates how we are driving value for advertisers across the full funnel. Total revenue came in at $763 million, up 11% on a reported and constant currency basis. Strength in overall revenue was driven by our awareness objectives and conversion objectives, including our lowest funnel shopping ads format. In the U.S. and Canada, revenue was $618 million, an increase of 8%, accelerating to the highest growth we've seen since Q3 '22. Strength came from CPG, retail and certain emerging categories like financial services and restaurants. Europe revenue was $114 million, growing 33%, or 25% on a constant currency basis. We experienced strong growth across CPG, emerging verticals such as travel, technology and auto and from large agencies. Revenue from Rest of World was $31 million, growing 29% or 28% on a constant currency basis. It is also useful to look at revenue through the lens of ad impressions and ad pricing trends. As we mentioned at our Investor Day, ad impressions growth is driven by total impressions, both organic and paid and ad load. Over the last several quarters, we've been able to drive increases in both total impressions and in ad loads simultaneously, thereby demonstrating that relevant ads can be synergistic with engagement. In Q3, we continued this trend with ad impressions growing 26%, driven from both increases in total impressions and increases in ad load. Meanwhile, the price of ads declined 12% this quarter. While pricing still remains under pressure, this is an improvement from the 20% decline we saw last quarter, driven by industry-wide demand stabilization as well as the AI-fueled ad stack efficiencies we drove on the platform in Q3. Now let's turn to expenses. Cost of revenue was $167 million, down 7% year-over-year and roughly flat versus Q2. This result is due to efficiencies being driven across storage and compute infrastructure, even amidst our strong user and engagement growth and continued AI deployment throughout our business. Overall, non-GAAP operating expense was $415 million, down 4% year-over-year and down 6% quarter-over-quarter. This outperformed our expectations and is a reflection of our overall focus on expense management as we realized additional cost savings in the quarter on lower spend in technology and outside services. We have been pleased by our ability to drive double-digit revenue growth even as operating expenses declined year-over-year. Adjusted EBITDA had a strong quarter, coming in at $185 million or a 24% margin, up 13 percentage points versus a year ago, driven by strong revenue performance, efficiency in our cost of revenue and the year-over-year decline in operating expenses. We ended the quarter with approximately $2.3 billion in cash, cash equivalents and marketable securities. Now I'd like to provide preliminary financial guidance for the fourth quarter. For the fourth quarter 2023, we expect revenue to grow in the 11% to 13% range, continuing the trajectory of accelerating year-over-year revenue growth throughout 2023. Our revenue guidance also takes into account a modest foreign exchange impact. Moving down the P&L. While we don't guide cost of revenue specifically, we do want to remind everyone that cost of revenue as a percentage of total revenue typically runs lower in Q4 due to the higher seasonal revenue we see in the fourth quarter. We expect Q4 non-GAAP operating expenses to decline in the 9% to 13% range year-over-year as we lap our large brand marketing campaign in Q4 last year. Please note that our operating expense guidance does not include cost of revenue. Finally, our focus on revenue growth and operational rigor has allowed us to meaningfully expand adjusted EBITDA margins over the course of this year. At the beginning of this year, we committed to 200 basis points of adjusted EBITDA margin expansion year-over-year for full year 2023. As the year progressed, we felt confident in our ability to exceed 200 basis points based on our expense discipline, and we doubled our commitment to roughly 400 basis points. Based on our progress in accelerating revenue growth and further controlling costs, we now expect to see significant adjusted EBITDA margin expansion again in Q4, which would put us on track to achieve approximately 600 basis points of adjusted EBITDA margin expansion for full year 2023. To close, our Q3 performance tells an impressive story, significant monthly active user growth, strong and accelerating revenue generation and effective cost management. all of which continues to put us on the path to deliver on the longer-term financial targets we recently provided. I'll now turn the call over to Bill.
