Thank you, Jen and good afternoon everyone. Q1 was a solid start to the year for Reddit, with strong results quite similar to each quarter since becoming a public company last year. Building on that thought, Q1 revenues were up 61%, consistent with revenue growth for the prior four quarters, which has averaged about 60%. Similarly, Q1 total adjusted costs were up 19%, consistent with the second half of 2024, where adjusted costs grew about 20%. The financial performance for Q1 was again defined by the five financial strategies that have been consistent over the past several quarters, highlighted the company's solid fundamentals and scalable model. These headlines include, one, differentiated revenue growth. In Q1, we delivered strong growth of 61% despite the tougher comps, well above most peers. Second, scaling profitably. Adjusted EBITDA hit $115 million in Q1 and GAAP net income reached $26 million. That's good progress to be GAAP profitable in our historically slowest seasonal quarter of the year. We're also now GAAP profitable on a trailing 12-month basis. Three, expanding margins. Adjusted EBITDA margin reached 29%, up over 2,500 basis points year-over-year, and the net income margin was 7%, up from a loss last year. Our incremental adjusted EBITDA margin was 70% plus for the fifth consecutive quarter. On the product side, gross margins expanded 190 basis points to 90.5%. Fourth, generating positive cash flow. Operating cash flow exceeded $100 million for the first quarter, ending at $128 million, our highest ever, and our operating cash flow margin was 33% of revenue. Fifth, minimizing dilution. Total diluted shares fell again sequentially to 206 million in Q1 as we continue to thoughtfully manage our share count. I'll provide a bit more color on these headlines. First, total revenue of $392 million was driven by our advertising revenue, which grew 61% year-over-year to $359 million and continues to scale rapidly across channels, verticals and geographies. Other revenue, which includes revenue from our data license business, reached $34 million, growing 66% year-over-year. Regionally, revenue grew 57% and 82% year-over-year in the U.S. and international, respectively. International revenue growth accelerated to the fastest growth in over three years, as we deepened and expanded our advertising relationships in important markets, including the U.K. and EMEA. In the quarter, we saw three encouraging revenue growth drivers. First, performance revenue drove more than half the dollar growth in the quarter. Second, our scale channel, including mid-market and SMB advertisers was also a growth driver, contributing more than $0.5 growth in the quarter. And third, impression continues to be the primary driver and consistent with other quarters. But new for this quarter, we also saw a nice tailwind from pricing in the quarter. We believe the gains in pricing reflect the progress from our investments in performance and targeting in the middle and lower funnel. We're delivering more clicks and conversions, which is driving more efficient ad spend and higher returns for our advertisers. Now, moving to costs. We continue to scale revenue -- as we continue to scale revenue, our investments are focused in two areas; hiring and technology. Hiring is focused on sales and engineering, which is primarily expanding customer coverage on the sales side and for engineering, we're adding resources in ad tech machine learning and search. The traction from those investments has been strong, and we found a sweet spot where we have both accelerated revenue growth and kept high incremental adjusted EBITDA margins, well above our long-term target of 50%. In Q1, total adjusted cost growth was up 1% sequentially and 19% year-over-year, less than one-third of the rate of revenue growth. Cost of revenue remained efficient with gross margins exceeding 90% for Q1, up 190 basis points year-over-year. Gross margins benefited from incremental revenue growth and we saw lower contract pricing from our hosting providers from the new contracts we signed late last year. That said, we reinvested some of those savings back across many important areas such as supporting user and ad revenue growth, using more machine learning, scaling search, accelerating machine translation from international markets, and better optimizing our site speed and performance across the world. OpEx growth was consistent with prior quarters, up 17% as total head count was up 13% year-over-year. We ended the quarter with slightly more than 2,300 people, up 3% sequentially. The G&A headcount was down 5% sequentially, reflecting our strategy to lever back of house expenses. I noted on the fourth quarter call that we're focused on scaling profitably and turning differentiated revenue growth, high margins and low CapEx in the meaningful cash flow generation. We delivered on those dimensions in Q1. Free cash flow for Q1 was $127 million, 32% of revenue. Our CapEx remained light, less than 1% -- less than $1 million in the quarter. Cash and investments ended at $1.95 billion, up over $110 million sequentially. That's a healthy gain. SBC was $107 million, about 27% of revenue, down substantially versus prior year, which reflected the catch-up SBC expense from the IPO. Net income was $26 million or $0.14 per basic share and $0.13 per diluted share. As we look ahead, we'll share our internal thoughts on revenue and adjusted EBITDA for the second quarter, which is where we have the greatest visibility. In the second quarter 2025, we estimate revenue in the range of $410 million to $430 million, representing 46% to 53% year-over-year revenue growth with a midpoint of about 50%. Adjusted EBITDA in the range of $110 million to $130 million, representing approximately 180% to 230% year-over-year growth. So it's good to see Reddit off to a strong start in 2025, our financial goal remains to continue to deliver consistent, strong and differentiated performance. In the end, we'll measure that differentiated financial performance primarily with cash flow. That concludes my comments. Let me turn the call back over to Steve.
