Thank you, Simon, and good afternoon, everyone. We are excited about the Cash App renewal, as well as the progress we have made over the last year on both go-to-market and efficiency initiatives. Before we discuss the financial aspects of the renewal, let me highlight our strong quarterly results. Second quarter net revenue growth of 24% gross profit growth of 8% and a positive, adjusted EBITDA margin, were all above our expectations, driven by stronger volume growth from several of our top customers, as well as expense savings achieved through efficiency efforts, particularly within technology, as well as our restructuring in May. Q2, TPV was 54 billion growing 33% year-over-year, continuing to demonstrate our growth at scale. The financial services vertical continues to be the highest contributor to growth growing several points faster than the company as a whole. This was fueled by Cash Apps continued growth, and transacting active card holders, and higher-spend-proactive user, as well as customers with accelerated wage access use cases ramping rapidly. Lending, including by now pay later, growth was boosted by increased travel spend, as well as the relatively new offerings that deliver our customers the NPL value proposition through a card that can be used at any merchant. Excluding Klarna, which migrated a portion of one program in Q3 2022, the NPL growth was similar to the overall company growth. Expense management TPV also grew in line with the overall company as a whole, slowing when compared to prior quarters due to tougher comps and maturity of the vertical. Q2 net revenue was $231 million growing 24% year-over-year, as growth remains strong across multiple verticals, including financial services and on-demand delivery, as well as our powered by Marqeta business. Block continues to be a strong contributor to growth, as our net revenue concentration increased to 78% in Q2 up about 2 points from Q1. Our net revenue take rate was consistent with last quarter and three bips lower than Q2 of last year. The decline versus last year is mostly driven by a mix shift toward powered by Marqeta volume, as our managed by Marqeta take rate increased two bips driven by increases in each of our major verticals, except for BNPL. Q2 gross profit was $85 million growing 8%. This growth is about 5 points faster than we expected, roughly a third of which was driven by stronger volumes and a remainder driven by unexpected incentive benefit. That was a catch-up from previous periods following a review with one of our network partners. Gross profit growth was low in the quarter for four primary reasons. One, we renewed approximately 50% of our non-blocked TPV between Q2 of 2022 and Q1 of 2023, lowering growth by mid-to-high single digits. Two, we lost a portion of our TPV from one Klarna program starting in Q3 last year, lowering growth by mid-single digits. Three, incentive timing, as our incentive contracts run from April to March each year, meaning that every Q2 we are starting from zero and build up our volume towards incentive tiers. Due to changes in Visa incentives, we filled the tiers slower in Q2 than we did last year, lowering growth by low single digits. Four, we lost four Visa incentives for two of our customers at the start of 2023, lowering growth by mid-single digits. Finally, the unexpected incentive benefiting Q2 was partially offset by lower ticket sizes, which lowers gross profit because of the per transaction component of network fees versus the per transaction component of interchange. The first three of these factors will no longer be impactful by the end of this year, and we believe these were relatively unique situations that impacted us all at once because of how much our business accelerated coming out of the pandemic. The fourth factor will lap in Q1, 2024, and shouldn't re-occur based on our new contract with Visa. Gross margin was 37%, Q2 is typically our lowest margin quarter of the year because of the incentive timing. While the Block net revenue concentration has steadily increased over the past four quarters, the Block gross profit concentration has remained relatively steady. This is due to less favorable volume mix within the Block business and improving margins in our non-Block business. The increasing revenue concentration is weighing our overall margin since our Block margin is over 40 points lower than the rest of the business. Our Q2 gross profit growth, excluding Block, Klarna and normalizing for items like the unexpected incentive benefit, is about two and a half times faster than the business as a whole. Driven by customers with higher margins growing faster than others, which is more than offsetting the impact from renewals we are still lapping, as well as the loss of certain Visa incentives at the start of this year. Q2 adjusted operating expenses were $84 million, a decrease of 10% from last quarter and a 5% decrease year-over-year, despite a one point of organic growth driven by the inclusion of Power. Our restructuring in late May reduced our workforce by approximately 20% resulting in Q2 savings of 6 million. On a run rate basis going forward, we expect quarterly restructuring savings of approximately 11 million after we reinvest in new head counting priority areas resulting in a net reduction of over 15% of the pre restructuring headcount plan. Our expense reduction in Q2 was not just the result of restructuring. We have many efficiency initiatives underway. Our technology expenses, which include Cloud and SaaS tool costs, were flat in Q2 versus last year despite year-over-year transaction growth of over 40%. We are leveraging automation and executing thorough reviews of our usage to improve efficiency while simultaneously improving our uptime, security and performance. We also continue to be mindful of hiring as well as cost associated with headcounts such as travel and reducing our usage of contractors and consultants. We recorded a onetime restructuring charge of 8 million related to severance, net of the release of bonus accruals and share base compensation forfeitures, all of which is excluded from adjusted operating expenses and EBITDA. Q2 adjusted EBITDA was positive one million margin of 0.4%. This result was better than expected driven by gross profit growth and cost management successes. Interest income was $11 million driven by elevated interest rates. The Q2 GAAP loss -- net loss was $59 million, including a $10 million onetime non-cash post combination expense related to the power acquisition as well as the one-time restructuring cost of $8 million. During Q2, we announced the stock buyback of 200 million. As of quarter end, we purchased 10.2 million shares for an average price of $4.75 for $48.5 million. We ended the quarter with $1.4 billion of cash and short term investments. Now let's shift to our Q3 outlook, as well as the Cash App renewal. Let me set aside the Cash App renewal for a minute and talk briefly about the business trajectory. The underlying performance of the business is a little stronger coming out of Q2 than we expected a quarter ago. In addition, some of the drags on gross profit growth in Q2 are dissipating in Q3. We expect high single digits percentage points less drag in Q3 versus Q2 from just two factors, the lapping of the Klarna volume loss and starting to lap some of the heavy renewal activity last year. We will continue to see low single digit percentage point gross profit growth headwinds in Q3 from incentive timing as we ramp through the tiers more slowly in 2022, but that will correct itself by year end. Moving on to the Cash App renewal, we are excited to extend our partnership another four years as both parties recognize the growth and innovation that we enable and the success we enjoy together. As we anticipated, Cash App is receiving improved economics given the growth trajectory since our last renewal in 2021. We believe the best proxy for our price, and therefore the way to measure the economic impact of the renewal is the impact to our gross profit take rate, which measures how much gross profit we earn for every dollar of Cash App TPV. Looking ahead to Q3 and Q4 of 2023, we expect the gross profit take rate we earn on Cash App volume to be approximately 40% lower as a result of the renewal. We believe this price is very fair for both parties commensurate with market rates for Cash App scale while accounting for the additional services we provide and our differentiated platform capabilities. We are excited to move forward for the next four years. The renewal has two structural changes that are important to note. First the pricing construct. We previously used a net interchange pricing construct, where we aggregate the interchange network fees and bank fees together and then determine the split between Marqeta and Cash App based on volume tiers. In the new pricing construct, start starting from July 2023, we will charge Cash App at price for the services we provide based on volume tiers. While the interchange network and bank fees are passed directly to Cash App. This new construct more clearly defines the price we charge for the value we provide while reducing volatility caused by several business mix factors. We already use this pricing construct with a few other customers, and in those cases, it does not change how the business is presented in our P&L. The second structural change is consequential to our revenue presentation. As part of the renewal, Cash App is taking responsibility for the primary payment network relationship. While we still provide Cash App with the same level of support on every other aspect of the program, they will manage the primary payment network relationship, although we do not receive incentives on Cash App volume from that network, this change is significant because the costs associated with Cash Apps primary payment network volume will in substance no longer be reflected in our P&L. Previously, we were responsible for this relationship and therefore these costs were presented in both our net revenue and cost of revenue. That will no longer be the case starting in Q3 2023. To be clear, this expected change in revenue presentation has zero impact on our gross profit. But it will materially reduce our reported net revenue. To put the net revenue impact in perspective in Q3, and Q4 of 2023 the impact of the accounting change will reduce our net revenue by approximately six times the amount of the price reduction tied to the Cash App renewal. Now let's talk specifically about our Q3 outlook. First, let me reiterate that the underlying performance of the business is a little stronger coming out of Q2 than what we thought a quarter ago. Second, for each of the next four quarters, we plan to share the impact of the Cash App renewal on our numbers given the significance. Our expectations for Q3 are as follows; net revenue is expected to contract by between 49% and 51% with an approximately mid 70s percentage point decline due to the Cash App renewal. Roughly 15% of the renewal impact is a result of the new pricing terms, while the remaining 85% is due to our anticipated shift in accounting treatment. Gross Profit is expected to contract between 9% and 11% with an approximately mid-to-high 20s percentage point decline due to the Cash App renewal. Our gross margin should be in the low 70s. Given the success of our efficiency efforts, year-to-date, as well as the restructuring completed in Q2 we expect adjusted operating expenses to decline by a high single digit percentage. Therefore, adjusted EBITDA margin is expected to be negative 12% to 14% on an organic basis, excluding the one point negative margin impact of the Power acquisition. This includes in approximately mid-teens percentage point decline due to the Cash App renewal, almost half of which is due to the new accounting treatment because of the lower revenue denominator. Consistent with what we thought a quarter ago, we expect our Q4 for performance to be a little better than Q3 as we continue to lag the impact of heavy renewal activity in 2022. Compared to Q3, we expect net revenue growth to be one to two points better, gross profit to be three to four points better and adjusted EBITDA margin to be four to five points better. We anticipate that the Cash App renewal impact will be similar in both quarters. Therefore, full year 2023 performance is expected to be the following; net revenue is expected to contract by a low teens percentage with an approximately low 40s percentage point decline due to the Cash App renewal, the large majority of which is due to the anticipated change in accounting treatment for Cash App related revenue. Gross Profit growth is expected to be positive low single digits with an approximately low to mid-teens percentage point negative impact due to the Cash App renewal. Adjusted EBITDA margin is expected to be negative low to mid-single digits on an organic basis, excluding approximately one point negative margin impact of the Power acquisition. This includes an approximately mid-to-high single digit decline due to the Cash App renewal. This 2023 adjusted EBITDA margin, even with the negative impact of the Cash App renewal, and the expected new revenue presentation for half of the year, is consistent with our expectations at the beginning of the year, excluding the Block renewal. This is primarily due to our cost reduction efforts, which have been achieved while accelerating sales and without a slowdown in innovation. Without the Cash App renewal, we believe we would have been EBITDA positive this year, whereas now we expect to exit 2024 at a positive EBITDA run rate. To wrap up, we delivered a strong Q2 across all metrics and have been making significant progress to position the company for long-term success. Our bookings continue to show strong growth and momentum as we capitalize on the expanding embedded finance opportunities, which should help diversify our business with strong sustainable growth. We made significant progress toward our operating efficiency goals with our restructuring efforts, as well as our overall focus on reductions across all expense categories. And of course, our renewal with Cash App establishes a new baseline and sets us up for sustained long-term profitable growth. Before we go to Q&A, we understand the longer term trajectory of the business including the Cash App renewal impacts are a great of great interest. But we will not be discussing 2024 performance implication during today's call beyond the fact that we will exit 2024 with positive EBITDA. However, we plan to host an investor day in Q4 to discuss the longer term with more details to follow. Now let's turn it over to Q&A.
