Thank you, Paul, and hello, everyone. Before I get into the details, given this is my first call as CFO of Amex GBT, I want to share my 3 key priorities when it comes to managing our financial performance. Firstly, achieving outstanding financial results by growing revenues, growing adjusted EBITDA and increasing free cash flow. This has been a key strategic priority for Amex GBT, and remains a critical area of focus. Secondly, and importantly, driving continued margin improvement. And finally, creating capacity to invest and drive long-term sustained growth. And so now let's turn to the highlights. We had a fantastic quarter, thanks to the continued hard work across our team to drive performance. As you heard from Paul, we delivered strong revenue and adjusted EBITDA growth. As you think about our performance, we were above guidance in Q2 as a result of revenue outperformance, driven by higher volume and higher revenue yield. We saw continued momentum in the second quarter across our 3 financial priorities. And very importantly, we returned to positive free cash flow. We continue to reduce our net leverage ratio and delivered year-over-year margin improvement, all the while allocating incremental investment dollars with an eye toward driving longer-term growth. Looking at the second quarter results in more detail. Revenue increased 22% to reach $592 million. This was ahead of our guidance. As I mentioned in my opening summary, this was partially driven by our strong transaction growth, which was roughly 3 percentage points ahead of our expectations, but also by our yield. As a reminder, our yield is measured as revenue [indiscernible] TTV and reached 8.1% in Q2. The strong revenue yield in the quarter was also 30 basis points ahead of our expectations driven by higher performance incentives. And as such, travel revenue increased 23% year-over-year. Note there is a phasing impact on the revenue across the quarters that somewhat skewed year-over-year revenue growth compared to transaction and TTV growth. I encourage you to look at H1 as a whole. Products and Professional Services revenue increased 16% with increasing demand coming from meetings and events and management fees. Now before we talk about adjusted EBITDA, let's discuss expenses. Our adjusted operating expenses increased 11% in the quarter, whilst revenues grew 22%. Strong transactional growth drove increased cost of revenue and investments in the business resulted in higher sales, marketing and technology expense. These were partially offset by cost savings and Egencia synergies. And so, this performance translates into delivering $106 million of adjusted EBITDA and continued margin expansion in the second quarter. Adjusted EBITDA margin reached 18%, up 8 percentage points year-over-year and notably the strong margin performance was also ahead of full year 2019 pro forma adjusted EBITDA margin. As I said in my opening comments, we reached a pivotal moment for the company in the second quarter with the achievement of $19 million in positive free cash flow. As expected, our working capital position significantly improved versus Q1. This is in line with the volumes, working capital and cash flow seasonality we outlined in detail last quarter. And as a result, we reported positive cash provided by operating activities. On our last call, I discussed the Egencia working capital initiatives, which will drive material benefits over the next 12 months. I am pleased to say that we have realized some of these benefits earlier than expected and this is really what drove our positive free cash flow in the quarter, which was ahead of our expectations and largely breakeven. Our leverage ratio or net debt divided by last 12 months adjusted EBITDA is approximately 3.5x as of June 30. This is a significant step down for us as a company and a critical proof point in terms of our momentum. Additionally, the reduction in our leverage ratio will drive 75 basis points interest rate reduction on our outstanding term loan beginning in the fourth quarter. By 2023 year-end, we expect leverage of less than 3x and continue to target 2x to 3x net leverage as our target leverage ratio. Our positive outlook for growth over the remainder of the year is supported by our customers and industry experts. Based on our August survey, on average, our customers expect continued solid year-over-year growth in their travel spend in H2 2023, including 84% of our top 100 customers expecting their travel spend to be flat or up in the second half of 2023 versus the second half of 2022. The highest growth is expected across the industrial, communication services, financial services and insurance services. And this is aligned with Morgan Stanley's most recent corporate travel survey, which shows expectations for 9% corporate travel growth in the second half of 2023, and 8% growth expected in 2024. And so let's turn to guidance and key drivers, starting with third quarter of 2023. We expect to deliver revenue between $545 million and $560 million, representing growth of 12% to 15%. This is built on expectations for around 9% transaction growth as we continue to normalize year-over-year and a revenue yield slightly lower than the first and second quarter given the seasonality of our business. We expect operating expenses to trend down sequentially in the third quarter, this is driven by the changes we announced in January relating to our reorganization, which are creating operational efficiencies and reflects our continued focus on cost. This results in third quarter expectations for $85 million to $95 million in adjusted EBITDA with an adjusted EBITDA margin of 16% to 17%, representing year-over-year adjusted EBITDA margin expansion of 8 to 9 percentage points. We have provided Q4 guidance based on our year-to-date results and our Q3 and updated full year guidance. As mentioned, our expectations for H2 have increased, but it's important to remember the seasonality of our business where H1 is stronger than H2. We expect strong transaction growth to continue in Q4 with a yield in line with full year expectations. Revenue growth in Q4 is lower due to the outperformance of supply yield in the fourth quarter of 2022. I would encourage you to look at transaction growth to understand our momentum and H2 year-over-year growth in aggregate. I refer you to the appendix of our earnings presentation for more detail. As we focus on full year 2023, as you've heard, we are now guiding to revenues between $2.25 billion and $2.28 billion, which represents 22% to 23% revenue growth. This translates into $70 million incremental revenue at the midpoint of our guidance. This increased revenue expectation is based upon our H1 performance, strong volume momentum and our confidence in our previous full year revenue yield guidance of 7.8%. On the cost side, we remain focused on our operating expenses, where we expect single-digit growth versus revenue growth of 22% to 23%. This demonstrates the leverage in the model as we have improved operational efficiencies, realized cost synergies and achieved benefits from the reorganization. We continue to expect cost savings to accelerate in the second half of the year, driving a reduction in expenses compared to the first half of the year. And so this results in an incremental $25 million of adjusted EBITDA at the midpoint. Now I recognize that we would typically expect a pull-through of approximately $45 million on incremental revenue of $70 million. However, as mentioned last quarter, we have some delayed execution of our European restructuring plan, which has impacted the phasing of our cost reduction. But importantly, we are making incremental product and technology investments in the balance of the year to further strengthen our competitive position. In total, we expect these 2 items to have approximately $20 million impact. We are now guiding to full year adjusted EBITDA between $365 million and $385 million. Our productivity gains and high operating leverage are expected to deliver 10 to 11 points of full year adjusted EBITDA margin expansion. We now expect a margin of 16% to 17%, which is at the higher end of our previous guidance. We anticipate generating positive free cash flow during the second half of the year with much stronger results in Q4 versus Q3 due to seasonality. We are confident in our ability to deliver this given our growth expectations, the seasonality of our working capital and the Egencia working capital optimization plan, and continue to target 2x to 3x net leverage as our target leverage ratio. So in summary, I am confident about our financial performance and the trajectory. We delivered strong second quarter revenue growth, significant adjusted EBITDA margin expansion, positive free cash flow, reduced our net leverage ratio and created some capacity to invest for the longer-term growth. Our confidence in our forward outlook is underpinned by the expectations for the continued growth in business travel, strong SME growth and share gains, and reflected in our increase in guidance. We expect to deliver strong results over the balance of the year. So we can now move into Q&A. Paul and I are joined by Eric Bock, who is our Chief Legal Officer, Global Head of M&A and Compliance and Corporate Secretary. Operator, please go ahead and open the line.
