Thank you, Barry and welcome to everyone and thank you for joining our first quarter earnings call. Before I begin, I'd like to extend a sincere thank you to Martine Gerow, our Chief Financial Officer, for her strong leadership and significant contribution to our business. As I mentioned on our previous quarter's call, this is actually Martine's last earnings call with us as she steps down from the CFO role at the end of June to join Accor as Group CFO. Karen Williams, who has been working very closely with Martine over the last year since she joined Amex GBT as Deputy CFO last May, is going to take over as CFO effective July 1 and of course, Karen is here with us on the call today. Just as a reminder, Karen joined us from IHG. She also worked at Avios and American Express, where she held several senior finance leadership roles and I am very confident that we are going to have a smooth and successful transition. So I'm going to kick things off by reviewing the quarterly highlights before then turning it over to Martine, who will take us through the financials. Karen will then go through our outlook and our guidance for 2023. So we reported a strong start to 2023 in the first quarter, driven by continued growth in business travel, significant new wins, continued momentum in the SME segment and significant margin expansion. Our first quarter revenue and adjusted EBITDA were both ahead of guidance and showed strong year-over-year growth. Revenue totaled $578 million, up 65% year-over-year. Q1 adjusted EBITDA totaled $99 million, nearly reaching our adjusted EBITDA total for all of 2022, and we delivered an adjusted EBITDA margin of 17%. And with these strong first quarter results, we remain very confident in delivering our full year guidance. Our results also demonstrate continued momentum with SME customers. In the SME customer segment, we benefit from offering a choice of market-leading solutions, Amex GBT, Egencia and Ovation in a very large and unconsolidated customer segment, a segment with the fastest growth and the highest margins in the industry. SME transactions grew 61% year-over-year, reaching 88% of 2019 levels. Our last 12 months SME new wins value reached $2.2 billion of annual TTV and that's based on the current recovery levels. Within this, approximately 30% of our SME new wins value over the last 12 months is now from the unmanaged category. So both our last 12 months SME new wins value in total and the share coming from unmanaged customers increased versus the fourth quarter of 2022. Total transactions grew 61% year-over-year to reach 76% of 2019 levels, clearly ahead of the broader travel management industry. On a workday adjusted basis, total transaction recovery was actually 74%. Now unlike previous quarters, the first quarter of 2023 had 1.5 additional workdays versus 2019, which benefited the Q1 2023 reported recovery by about 2 points. Our significant new wins position us well for continued strong growth ahead and clearly demonstrate that we continue to deliver on the significant organic growth opportunity we have ahead of 1 billion. And finally, our customer retention rate over the last 12 months remains very stable at 95%. So overall, we delivered strong revenue and adjusted EBITDA, continued growth in business travel, combined with share gains, SME momentum and proven operating leverage gives us confidence as we look ahead to the balance of 2023 and beyond. So on Slide 7, let's take a closer look at our strong year-over-year growth. As I mentioned, Q1 transactions increased 61% to reach 76% of 2019 or 74 or work day adjusted basis. That 74% transaction recovery represents a 2-point sequential increase in transaction recovery versus the fourth quarter of 2022, which is consistent with what we have guided in previous discussions. TTV increased 88% year-over-year in the first quarter and benefited from really strong international growth year-over-year. Finally, revenues grew 65% year-over-year in the quarter to reach 83% of 2019 levels. On next page, I'm going to look at the growth trends in more detail. You'll see by customer segment here, global multinational transaction growth was level with SME customer transaction growth in the quarter with both up 61% year-over-year. International growth, as I just mentioned, very strong in the quarter. International transactions up 81% year-over-year. We have said in previous calls that travel restrictions around the world are listed, strong growth follows. And we're clearly seeing that in our results, particularly in our international recovery. Growth in hotel transactions outpaced air by 2 percentage points, up 62% and 60%, respectively. And as mentioned previously, we are making very good progress, increasing the ratio of hotel to air bookings. We've achieved this by continuing to improve the hotel content and the displays in our proprietary software platforms, both Egencia and Neo. We're seeing particular strength in the SME segment and important to note, Egencia hotel transactions were 111% of 2019 levels in the first quarter. On a regional basis, you can see that Asia Pacific was the clear standout with 114% year-over-year growth in the quarter driven by the relaxation and removal of travel restrictions in China, in Hong Kong and Singapore. EMEA transactions increased 63%. We estimate that industrial actions that took place across France, Spain, Belgium, Germany, had approximately a 1 percentage point negative impact on the global transaction recovery in March. Finally, the Americas was up 52%. So let's now turn to our commercial highlights for the quarter. We delivered strong new wins and continue to progress our product and our technology leadership. We are the clear leader in a $1.2 trillion industry with a significant runway for growth. We continue to gain share with $3.4 billion of total new wins value over the last 12 months, supported, of course, by very strong customer retention of 95%. Our biggest growth opportunity, of course, remains in the SME segment. This represents a total opportunity of $950 billion of travel spend. Within the SME customer segment, we are the number 1 player in managed travel. But only 30% of that $950 billion opportunity is actually managed today, providing a significant growth opportunity in the managed and memos in the unmanaged segment. And you can see we're making good progress. We signed $2.2 billion of SME new wins value over the last 12 months. Of this, approximately 30% of the value of that $2.2 billion, and 55% of the customers of from companies whose travel programs were previously unmanaged, which I think really demonstrates that we continue to gain traction, and we're converting this unmanaged customer travel opportunity into managed travel spend. Also supporting our technology leadership, we recently announced customer pilots and rollouts for the booking of Air France-KLM NDC content across our proprietary software platforms, NEO and Egencia. This new NDC content will be enabled through Amadeus in a way that fully meets the needs of our corporate clients. And it's an important milestone because we have set a standard here that can be used by the managed travel industry to ensure a successful and scalable launch of NDC content in a way that fully meets the needs of corporate customers. We continue to advance our technology to help our customers to reach their sustainability goals. This quarter, in Egencia, for example, the moment of traveler searches for rail content, they'll now see carbon emission details across all available routes to help travelers make more sustainable choices. Travelers and arrangers can now effortlessly sort, locate and book hotels with environmental certifications. And we also added additional carbon emission data into NEO, our proprietary online travel and expense platform through a new partnership that we have with a leading client tech company choose. We reported record transactions on the Neo travel and expense software platform in the first quarter. 76% of all of our transactions now come through digital channels. And we continue to increase the share of this volume coming through our own proprietary software solutions, both NEO and Egencia. Increasing the number of transactions, on our own software platforms is really important because it improves the customer experience and it increases productivity and margins in our business. I'm very pleased to say that Q1 was the highest quarter of all time in terms of Neo transaction volumes. So on Slide 10, when we were on the path towards becoming a public company, we shared our strategic priorities to nearly one year since going public later this month. I am very pleased to say that we are clearly delivering on these commitments and creating strong momentum for the future. First of all, business travel momentum indeed continues. Q1 year-over-year revenue growth was 65%, transaction growth, 61%. Strong start to the year that gives us confidence that we're on track to achieve our full year guidance. Secondly, our new sales pipeline, strong new wins, continued share gains position us for continued strong growth in the future. Our new wins value reached $3.4 billion over the last 12 months based on the current recovery levels. Third, we said our focus on winning in the SME segment would accelerate growth and our results clearly show strong progress in this area. Q1 SME transaction recovery reached 88%. We reported SME new wins value of $2.2 billion over the last 12 months, up from $2.1 billion in the fourth quarter and we also announced accelerated new wins coming from the unmanaged segment, $660 million of new wins from the unmanaged segment, 30% of the new wins. And that $660 million of new wins from the unmanaged segment is 25% higher than it was in the fourth quarter. Fourth, we are delivering on the Egencia of synergies. We're on track to deliver approximately $60 million of Egencia synergies in the full year 2023 based on actions we've already completed some expected synergies from Egencia at the full recovery level. Fifth, our business model is clearly delivering the operating leverage we committed to. Last quarter, we said we added costs to support incremental volumes heading into Q1. In the first quarter of this year, we actually reported over 100% adjusted EBITDA fall-through versus Q4. Meaning, sequentially versus Q4, we delivered incremental adjusted EBITDA that actually exceeded incremental revenue. And finally, all these results combined to deliver significant margin expansion. In the first quarter, we reported a 17% adjusted EBITDA margin with volume growth, higher online adoption and structural changes creating operating efficiencies. So to sum up our first quarter performance, I think it provides yet another proof point of our continued strategic commercial and financial progress. So that completes my review of the Q1 highlights, I'd now like to hand it over to Martine, who will discuss the financial results in more detail. Martine?
