Thank you, Simon, and good afternoon, everyone. Our Q1 results represent a strong start to the year with all of our key metrics exceeding our expectations. TPV grew 33% with broad-based outperformance, particularly in BNPL, on-demand delivery and financial services. The stronger-than-expected TBV growth drove net revenue to the high end of our expected range. Gross profit meaningfully outperformed due to those volume gains and the benefit of capturing additional network incentives, which I will discuss later in more detail. Finally, continued execution of efficiency initiatives, particularly the streamlining of technology costs, when coupled with our higher gross profit led to significantly higher adjusted EBITDA of $9 million in the quarter. Q1 TPV was $67 billion, a year-over-year increase of 33% for the fourth straight quarter. Non-Block TBV grew approximately 15 points faster than Block growth. The financial services vertical grew in line with the company overall as neobanking which some of our customers combined with accelerated wage access solutions continues to resonate with consumers. Lending, including Buy Now, Pay Later grew faster than the overall company due to the continued adoption of our BNPL customers pay anywhere card solutions. On-demand delivery growth remained in the double digits, accelerating quarter-over-quarter as our customers expanded into new merchant categories and geographies. Q1 had our highest on-demand delivery TPV growth in the last 2 years. Expense management growth accelerated for the second straight quarter, growing on par with the overall company, driven mainly by strong performance from our top customers. In fact, one of these customers have been increasing the share of their volume on our platform after seeking platform diversification with a competitor in the past. The most Q1 net revenue was $118 million, a contraction of 46% year-over-year. The key elements of our net revenue results are as follows: the most significant impact was the 58 point growth headwind related solely to the revenue presentation change resulting from the cash renewal. As we've described before, this change in revenue presentation is related to the bank and network fees associated with Cash App's primary payment network volume, which previously were included in net revenue and cost of revenue. Starting in Q3 '23, these costs are netted against revenue. There is an additional 10 percentage points decline in net revenue growth due to the Cash App renewal pricing. There was one additional revenue presentation impact related to our Cash App renewal this quarter. We renegotiated a platform partner agreement with reduced pricing that went into effect this quarter. Due to the terms of the Cash App renewal, we passed through the proportional savings to Cash App. Based on the revenue presentation changes we made last year, this reduced pricing impacts Cash App net revenue, but not gross profit. The impact was approximately $4 million, lowering our Q1 growth rate by approximately 2 points. This partner agreement impact was not contemplated when we last shared our 2024 expectations in February. Non-Block revenue growth accelerated quarter-over-quarter by 3 points as we lap some of the prior year renewals. We continue to see increased contributions from fast-growing solutions such as BNPL, PayMe work cards, on-demand delivery category expansion, and neobanking combined with accelerated wage access. Block net revenue concentration was 49% in Q1, decreasing 2 points from Q4. The decline in concentration is helped by the broad outperformance from other customers on our platform, particularly larger customers. Excluding Block, our top 10 customers increased net revenue by 30% year-over-year. Our net revenue take rate of 18 basis points declined 1 point from last quarter due to seasonality as the mix of our TPV during the holiday season typically has a higher take rate. Q1 gross profit was $84 million, a gross profit margin of 71%, outperforming our expectations primarily due to higher network incentives. In the simplest terms, our stronger TPV trajectory across multiple networks over the last couple of quarters led to this benefit. In the case of one partner in particular, in the final days of the quarter, we reached another incentive tier, generating a gross profit benefit for the quarter before our incentive tiers reset in April. As a reminder, our 2 largest network incentive contracts run April to March, which results in Q1 being our highest incentive quarter and Q2 being the lowest. On a year-over-year basis, our gross profit contracted 6%. While we are starting to see the newer higher gross profit cohorts begin to contribute, renewals continue to weigh on gross profit growth. The Cash App renewal lowered gross profit growth by mid-20s percentage points. As a reminder, the Cash App revenue presentation changes do not impact gross profit. In addition, although the renewals lowered growth by mid-single digits. Roughly half of this impact is driven by renewals completed between Q2 2022 and Q1 2023, which will lap in Q2. The remaining impact is driven by the Square renewal, which won't anniversary until Q4. Non-Block gross profit growth accelerated quarter-over-quarter by 7 points, helped by the higher incentives. Our gross profit take rate was 13 basis points, consistent with the last 2 quarters. Q1 adjusted operating expenses were $75 million, a decrease of 20% year-over-year due to realized savings from our restructuring in May last year and efficiency initiatives targeting our technology and professional service expenses. We continue to find opportunities to optimize our operations and execution while maintaining high reliability. On a sequential basis, expenses shrank 6% quarter-over-quarter, largely due to a decrease in professional services, which tend to be higher in Q4 due to the timing of audit fees as well as product and security assessments. Q1 adjusted EBITDA was positive $9 million, resulting in a margin of 8%. Interest income was $14 million, driven by continued elevated interest rates. The Q1 GAAP net loss was $36 million, including a $10 million noncash post-combination expense related to the Power acquisition. Within Q1, we exhausted the $200 million buyback authorization announced in May of 2023. In the quarter, we purchased 5.2 million shares at an average price of $6.22 for $32.7 million. We ended the quarter with $1.2 billion of cash and short-term investments. Now let's shift to our Q2 and full year outlook. We expect Q2 net revenue to contract between 47% and 50%. This is in line with the expectations we shared last quarter with the exception of the 2-point revenue presentation impact related to the renegotiated platform partnership. Consistent with what we have seen in the last 3 quarters, we have assumed a 65 to 70 percentage point negative impact of the cash app renewal. Q2 gross profit is expected to contract between 7% and 9%, a little better than our expectations at the start of the year based on our current trajectory. We expect gross profit margin to be in the low to mid-60s as our network incentive tiers with our 2 largest network partners reset every April. Therefore, Q2 is always our lowest gross profit quarter. Q2 adjusted operating expenses are expected to grow in the low single digits as we start to lap our restructuring from last May. This is also better than our expectations at the start of the year due to optimization initiatives, but we will continue to reinvest in headcount and enhance platform resiliency to support the growth of our scaled customers. Therefore, Q2 adjusted EBITDA margin is expected to be in the negative 5% to 7% range, 2 points better than our expectations at the start of the year. Although the reset of our network incentives will lead to negative adjusted EBITDA in the quarter, barring unforeseen macroeconomic events, we expect this to be our final negative adjusted EBITDA quarter as we move forward on our path of sustainable profitable growth. Our expectations for the full year 2024 have increased for adjusted EBITDA and gross profit remains largely unchanged while reducing net revenue growth. We now expect net revenue to contract 24% to 27%. This is a 3- to 4-point reduction from what was shared previously, driven by 2 factors, neither of which are impactful to gross profit. First, the revenue presentation impact related to the renegotiated platform partnership is approximately 2.5 points for the year. Second, we now expect the mix of our TPV to be more heavily weighted toward the Powered by Marqeta business, which materially impacts net revenue but has a much lesser impact on gross profit. This will lower the revenue growth by approximately 1 point. Gross profit is now expected to grow 7% to 9%, lifting the bottom of the range from what we have shared previously. TPV year-to-date has been a little stronger, helping the first half gross profit growth, but the majority of the Q1 gross profit upside was related to incentives that are specific to Q1 because of the way our incentive contracts are structured. Our expectations for the second half gross profit growth remained unchanged for now at 23% to 26%. These changes in our net revenue and gross profit expectations highlight why we focus on gross profit as the measure of value we deliver for our customers. Our net revenue can be noisy based on our business mix and revenue presentation. Based on our continued success with cost optimization and efficiency initiatives, we are raising our full year adjusted EBITDA margin to positive 1% to 3%. We still expect positive adjusted EBITDA for 3 out of our 4 quarters in 2024 with Q2 being the exception. Before we wrap up, I wanted to address our stock-based compensation and the impact of Jason's election to step down as Executive Chairman. As we discussed during our Investor Day late last year, we are being more thoughtful in our deployment of stock-based compensation and are managing to a dilution target of below 3%. We are on track to meet our target in 2024, but it will take time for our increased discipline to impact our stock-based compensation due to the vesting of grants from prior years. For the past several quarters, approximately 30% of our stock-based compensation is driven by the accounting for Jason's pre-IPO long-term performance award, which consists of 7 equal tranches that vest upon the achievement of company stock price hurdles ranging from $67 to $173. For this award to be earned, it included very specific service requirements as the CEO or Executive Chairman. Therefore, Jason's decision to step down from the Executive Chairman role were resorting him forfeiting the award and the reversal of previously recognized expenses. This reversal will occur with the transition in June, resulting in a $158 million onetime benefit to stock-based compensation in Q2. In addition, we will no longer expense $32 million of stock-based compensation that we would have booked from Q2 to Q4 of this year. Therefore, this change will lower our 2024 stock-based compensation by $190 million compared to what was expected at the start of the year. This will also lower our 2025 expense by $18 million. While this does not change the timing of sustained net income profitability, it does substantially reduce our net income loss over the next 2 years. In fact, we now expect 2024 net income to be around breakeven to slightly positive due to the accounting of this forfeiture then going negative again in 2025 before reaching true and sustained profitability exiting 2026 as we laid out in our Investor Day late last year. In addition, Jason has elected to voluntarily convert a portion of its Class B shares to Class A shares on a one-for-one basis. Therefore, our Board has authorized another share repurchase program of up to $200 million. While we are not ready to commit to being a systematic buyer of our stock going forward, we continue to believe that our current valuation does not properly reflect the market opportunity, our differentiated and comprehensive offering and the expense discipline we have instilled in our business. This attractive path to sustainable profitable growth, combined with our strong balance sheet and limited cash burn, make this buyback program a great opportunity to reduce our shares outstanding at our current valuation as we continue to manage the business for the long term. In conclusion, we are starting 2024 with solid results and continuing to generate the momentum we've built over the last 18 months to deliver sustainable growth, profitability and innovation in 2024 and beyond. Once we lap the Cash App renewal impacts at the end of Q2, our second half financial metrics will begin to reflect what we believe is our true performance trajectory. Our success with efficiency initiatives is expected to deliver positive adjusted EBITDA in 2024 for the first time as a company while continuing to enhance our platform capabilities to capture the immense opportunities ahead with new and existing customers. I will now turn it over to the operator for Q&A.
