Thank you, Paul, and hello, everyone. In the first quarter, we continued to execute against my three key priorities in terms of managing our financial performance. We accelerated cash flow generation, drove operating leverage and continued margin expansion and importantly, continued to invest. This formula has driven amazing progress and strong financial results. It gives us confidence as we navigate through a more uncertain macroeconomic environment. So now let's turn to our financial performance in more detail. We continue to control what we can control and deliver on our commitments. Whilst transaction and revenue growth was about 1 percentage point below our expectations coming into the quarter, we still delivered adjusted EBITDA, adjusted EBITDA margin and free cash flow in line with the expectations we previously communicated for Q1. Revenue reached $621 million, up 4% year-over-year on a constant currency, workday-adjusted basis. On a reported basis, revenue was up 2%, reflecting a negative impact of 1 percentage point from FX and of 1 percentage point from fewer work days. Revenue yield, which we define as revenue divided by TTV was 7.4%. As expected, this was down 8 basis points year-on-year, reflecting the non-TTV-driven components of the revenue base and a continued shift to digital transactions, which has a positive impact on our adjusted EBITDA margin. And as a reminder, Q1 is seasonally a lower revenue yield quarter. Now let's turn to total operating expenses. I am incredibly pleased with the momentum we are seeing across the enterprise when it comes to our focus on costs and increasing productivity. We are clearly doing more with less. Adjusted operating expenses were down 1% year-over-year, driven by our cost-saving initiatives and productivity improvements. This enabled us to make continued investments in technology, content, sales and marketing to drive future growth and productivity. It is also worth noting that we had a favorable FX impact, as previously discussed, given the natural hedge between revenue and expense, the impact to adjusted EBITDA is neutral. Putting these together, adjusted EBITDA grew 15% to $141 million, and our adjusted EBITDA margin grew an impressive 260 basis points year-over-year to reach 23%. We saw continued momentum when it comes to cash and generated $26 million of free cash flow in the quarter, up 9% year-over-year. Moving to the balance sheet. Our leverage ratio of net debt divided by last 12 months adjusted EBITDA continue to deleverage to 1.7 times as of March 31, 2025. And as discussed on our last earnings call, we refinanced the entirety of our debt at the start of the quarter, lowering our interest rate by 50 basis points with the new term loan facility priced at SOFR plus 2.5%. And finally, but importantly, I am very pleased that we received 2 credit rating upgrades in the quarter from Moody's and S&P. These upgrades are recognition of our strong momentum. Our powerful financial model is more important than ever in an uncertain macroeconomic environment, and that is why we believe GBTG should be a preferred industry investment. We're confident that with our strong financial model, adjusted EBITDA will continue to outpace revenue growth. We expect business travel demand from our premium customer base to grow above GDP. Additionally, we expect to continue to grow ahead of the market by driving share gains with our differentiated value proposition. Our laser focus on operating efficiency, disciplined cost management and quite frankly, a track record here creates a significant runway for margin expansion, particularly as we leverage AI and automation. From a capital deployment perspective, we are incredibly focused on value creation. Our strong free cash flow generation can fund important incremental growth opportunities and M&A. And finally, but importantly, we are in a very strong position to return cash to shareholders. And so building on this in a little more detail. There are three key business attributes that make us confident and give us the stability to navigate through a period of uncertainty. First, our resilient and diversified revenue model. As a reminder, when airlines need to use price to stimulate demand of fill seats, 70% of our revenue is protected because it is volume-based or recurring product and professional services revenue, and only 30% moves in line with air fares and hotel prices. Furthermore, our revenue is roughly balanced between customers versus suppliers and the U.S. versus the Rest of the World. Because of this, we are less exposed to downturns through our suppliers during the economic cycle. The second attribute is a strong operating efficiency. And as I just mentioned, we have a clear track record in cost reduction. We came into this year with plans for $95 million in cost savings, but in light of current conditions, we have further increased the cost savings to a full year target of approximately $110 million in 2025. Paul discussed the progress we are making in our technology transformation strategy. We are intentionally growing our mix of digital transactions because it is more profitable. The efficiency we are achieving on the bottom line results in really strong incremental margins as new volumes flow through our platform. The third attribute is value creation opportunities. We have a strong cash balance of $552 million as of March 31, 2025, and over $900 million in available liquidity. This enables us to continue our investments in share gains, our software platforms, automation and AI. The macro environment doesn't have us reconsidering these investments. We have strong investment capacity and plan to invest an incremental $50 million this year in these initiatives. This incorporates CapEx productivity saves, where we are doing more with less, an updated OpEx spend phasing versus our previous expectations. Our business needs investment to accelerate growth and an uncertain macro environment, this plays to our strength. We have a strong balance sheet and incremental M&A drives value, particularly given our track record in delivering synergies with an experienced integration team. And finally, we have a $300 million share buyback authorization in place. Turning to the current transaction growth trends and customer outlook, we have no direct impact from tariffs. The headwind we are experiencing is from slower macroeconomic growth and its impact on our organic transaction volume. The trends have stabilized, and this is in line with the commentary you are likely to have heard from the major U.S. airlines. Transaction growth is currently trending flat year-over-year. This is down roughly 5 percentage points versus our expectations coming into the year, but we are not seeing any further signs of deterioration. The trend is based on looking at March and April together to normalize the Easter timing impact, consistent with our approach in prior years. Across the top five verticals, which account for approximately 70% of GMN transactions, we are seeing positive or broadly flat year-over-year growth. Six of our 15 U.S. GMN industry verticals sequentially improved from February to March and April, including IT, business and Professional Services and Pharma. However, two were largely flat and seven industries declined with a sequential slowdown in the sectors more exposed to tariffs, including consumer and automotive. A bright spot is our Meetings and Events business, which tends to be a forward indicator. We are currently seeing a 2% year-over-year increase in the number of meetings, an 8% increase in spend for full year 2025. Cancellation levels are in line with previous years. And so in our most recent survey of our top 100 global multinational customers, customer sentiment has moderately declined. Overall, 6% of the top 100 global multinational customers have put new budget controls in place since the April 2 tariff announcement. And so in light of this backdrop, let's move to our guidance. We are hitting the mark on what we can control. Our expectation for new wins remain unchanged and in fact, we have actually increased our cost savings. However, the macro environment is softer than we expected coming into the year and it is important to reflect the resulting slower organic travel growth. So let me be clear about the assumptions we are taking, and I will focus on the midpoint of our guidance. Because of our near-term visibility into Q2, we thought it helpful to provide Q2 guidance today. Our approach to guidance is based on a weaker economy and built on the assumption that the flat transaction growth we have seen over March and April continues. The flat workday adjusted transaction growth assumption is driven by a modest decline in organic transactions, offset by new wins. This results in Q2 midpoint expectations for $625 million in revenue or roughly flat year-over-year with adjusted operating expenses down modestly year-over-year. This includes our incremental investments demonstrating rigorous cost control. So importantly, strong adjusted EBITDA margin expansion continues, and therefore, we expect adjusted EBITDA to grow faster than revenue. We are guiding to $130 million in adjusted EBITDA at the midpoint, up 2% year-over-year and reflecting 50 basis points of margin expansion. So now let's turn to what that means for our full year 2025 guidance. Our updated guidance has changed to reflect the softening in current conditions and its impact on our organic transaction growth. The key message is our strong adjusted EBITDA margin expansion continues. We are bringing full year 2025 revenue down by just 4%, and adjusted EBITDA guidance down by just 6% at the midpoint, with the upper end, largely in line with the previous adjusted EBITDA guidance to this point. So our baseline assumption is now for flat total transaction growth for the full year. The breakdown is a 2% decline in organic transactions, offset by 2-percentage points positive impact from new wins. We are confident in our new wins and this assumption is unchanged. So overall, the midpoint of our guidance reflects flat revenue. This updated guidance assumes a neutral foreign exchange impact but as we have said previously, because of the natural hedge between revenue and operating expenses, changes in currency assumptions did not impact adjusted EBITDA. Accordingly, we are also updating our full year adjusted EBITDA guidance to reflect lower organic transaction growth, at a fall-through of about 65%. So clearly, we will exercise firm cost control with a total of $110 million in cost actions to protect our earnings and cash generation. But importantly, we are continuing to invest and expect to continue benefiting from the impressive productivity gains we have discussed. We are now guiding to full year midpoint adjusted EBITDA of $510 million, representing growth of 7%. Strong margin of 21% and margin expansion of 130 basis points. The takeaway is we still expect healthy adjusted EBITDA growth even with a softer economic environment. And finally, but very importantly, given our focus on cash, we still expect to generate a strong level of free cash. We are now guiding to full year free cash flow of $140 million at the midpoint, which is $190 million on an underlying basis, excluding the nonrecurring M&A-related costs we spoke about previously. So I want to end by reiterating our capital allocation priorities. Our first priority is continued cash generation. We are now guiding to the full year free cash flow of $140 million at the midpoint. As just highlighted, this is $190 million on an underlying basis, representing a free cash flow conversion rate, 37% of adjusted EBITDA. Second, continuing to deleverage. We expect our leverage ratio to remain at the bottom end of our target leverage ratio of 1.5 times to 2.5 times. We have a strong and flexible balance sheet with a cash balance of $552 million and over $900 million in available liquidity at the end of March. Third, our strong balance sheet gives us capacity to invest. While we are carefully managing our expenses, we are still increasing investments in areas that deliver more value to customers and make us a leading B2B software and services company. This includes investing in our marketplace and products to continue enhancing the customer experience, sales and marketing to drive growth and AI and automation to drive further margin expansion and efficiency. As mentioned, we expect to invest an incremental $50 million this year. Fourth, with respect to M&A, we amended our merger agreement for the CWT acquisition, including a reduction in the number of shares expected to be issued. We remain confident in the merits of our position in the lawsuit initiated by the DOJ and remain prepared to prove this in court, if required. The -- financing is primarily stock we expect to remain within our target leverage range following the transaction close. And finally, given our current stock price, which we believe is significantly undervalued, as well as our leverage and cash position, we are in a position of strength to execute against our $300 million share buyback authorization and return cash to shareholders. So our capital allocation strategy remains the same, and in a weaker environment, M&A and share buybacks become even more accretive. So track things up, our first quarter performance was strong, our resilient revenue model and strong operating leverage positions us to continue to drive shareholder value. With confidence in our long-term growth prospects and our approach to a slower growth environment is to remain focused on what we can control, share gains, margin expansion, cash generation and shareholder returns. We can now move into Q&A. Paul and I are joined by Eric Bock, who is our Chief Legal Officer and Global Head of M&A. Operator, please go ahead and open the line.
