Paul Abbott
CEO, American Express Global Business Travel

Thank you, Jennifer. Welcome everyone, and thank you for joining us this morning. In 2025, we delivered strong results and expect even stronger momentum in 2026. We are executing on our growth strategy. We continue to gain share and maintain an impressive customer retention rate. Product innovation is accelerating. Our strategic partnership with SAP Concur is well underway as we roll out Complete, a new flagship solution for travel and expense. We are launching next-gen Egencia in April with a new AI-powered user experience and full integration into Concur Expense. We closed on the acquisition of CWT in September of 2025. We are now at a very exciting inflection point where AI is delivering real revenue and cost benefits, and we are leveraging our platform to power the future of agentic AI and business travel. More on that shortly.

Finally, we doubled our share repurchase authorization to $600 million, supported by our strong balance sheet and robust cash flow. Given the current share price and our conviction in our long-term growth trajectory, we believe this represents a compelling driver of shareholder value. Before I talk in more detail about the value that we are delivering with AI, let me quickly review our strong 2025 performance. Here are the highlights. Total transaction value, or TTV, grew 17%. Revenue growth accelerated to 12%. Adjusted gross profit margin was 60%. Adjusted EBITDA grew 11%, and we generated $104 million of free cash flow. Finally here, excluding CWT, new wins value accelerated to $3.3 billion, and we maintained very strong customer retention rate of 96%. Amex GBT continues to grow and continues to gain share.

Our new wins performance increased demand from our premium customer base, high customer retention rate, and the acquisition of CWT resulted in impressive top-line performance. Our focus on operational efficiency and cost synergies enabled us to drive strong adjusted gross profit and Adjusted EBITDA margin performance. I now want to address market sentiment related to AI. Let me start by being clear on this. We have proven that automation is a tailwind for our business, a tailwind that is being accelerated by AI. We have already proven that digital adoption drives higher margins and drives higher profits. Over the last five years, we've increased our mix of digital transactions from approximately 60% to over 80%, with over 60% of those digital transactions on our own technology platforms.

Over the same period, our Adjusted EBITDA margin has gone from 17%- 20%, driven directly by increased automation. AI is accelerating this positive trend. Our broader AI strategy is focused on three key priorities: revolutionizing the customer experience, powering the agentic transformation of B2B travel, and reducing operating expenses. Why are we so confident that AI will supercharge value creation for our customers and our shareholders? Because we're already seeing it happen today. Here are some examples. AI is increasing self-service. Even for issues that still require a live agent, our agents are using AI tools to reduce handling times, giving a better experience for the customer and reducing operating costs. AI is also delivering higher revenue conversion in our products through enhanced personalization. Our tech teams are using AI to design and build products, improving both speed and quality.

Agentic AI is a decision-making and execution layer with the potential to reshape channels and workflows. The opportunity that we have in managed travel is to integrate agentic AI with all of our other services, including the supply inventory, company data, traveler data, duty of care processes, disruption management, and the end-to-end workflow to deliver the control and the experience that our customers demand. We can deliver this consistently and securely on a global basis. Our platform is being used today to power agentic AI experiences, both proprietary and through integration with third parties. In all these cases, Amex GBT is providing the essential assets required to power the agentic AI experience at scale. Now I'd like to introduce Evan Konwiser, our Chief Product and Strategy Officer, to share some specific examples of how we are executing on our AI strategy. Evan, over to you.

Evan Konwiser
Chief Product and Strategy Officer, American Express Global Business Travel

Thank you, Paul. As Paul said, we have deep conviction that AI is a clear tailwind in transforming our business by enhancing both the customer value prop and our profitability. Our central role in building and operating a platform that integrates enterprise workflows into the very real and dynamic world of travel represents a clear competitive advantage for us to lead in the AI transformation in corporate travel. To maximize this opportunity, we're investing for AI-powered growth and value creation across three key priorities. The first is revolutionizing the customer experience, incorporating AI and agentic capabilities into the way we service and support our customers and their travelers by delivering personalization, contextualization, and user delight. The second is taking our platforms to power the agentic transformation of B2B travel.

Amex GBT's platforms have been designed to execute travel at scale globally. Such a platform is an essential foundation to enable the agentic AI tools that companies are launching for many use cases today. Finally, AI is a generational opportunity to redefine our operating model and cost base, allowing us to expand margins and create more capacity to invest in one and two. I wanna highlight one example of how we're looking at revolutionizing the customer experience with AI. We know travelers want to conduct business from the channels that they're already using daily. We know that both companies and their travelers want integration into existing business workflows with immediate personalized responses and proactive actions to solve their needs.

Next month, we expect to launch Egencia AI, a tool that allows travelers to search, book, and change travel by responding to natural language interactions, all while adhering to company policy, personal preferences, and context, and of course, sourcing from the comprehensive and competitive inventory in the Amex GBT marketplace. This foundation is anticipated to grow to more proactive actions over time, including fully agentic capabilities. Already on Egencia, we have an average booking time of under three minutes, which is expected to go down even more with these new tools as AI agents complete more of the workload. We're able to source the majority of hotels within the top five options based on many years of training our models, making these experiences better. We're having success increasing self-service, and the new Egencia AI experience is projected to further accelerate that progress.

In short order, this will be available in a multitude of channels: the web, Egencia Mobile, as well as the major enterprise collaboration tools that most of our customers are using today. We have similar solutions arriving on Complete, our joint solution with SAP Concur, as well as Neo. With our service promise, there is always a live agent for travelers to access if the AI does not deliver what they need, or if they simply prefer some human interaction. This is only one example of how AI is helping us dramatically advance the customer and traveler experience, enhancing our ability to retain and win customers, and importantly, reduce bookings made outside the program by giving travelers tools that make it much easier and faster to book travel from Amex GBT. We believe our platform is central to transforming B2B travel with AI.

We are expecting AI agents to do a lot of the heavy lifting in business travel, but thoise AI agents will need access to the data, global inventory, workflows, and orchestration that has authority to fulfill travel bookings, manage approvals and payments, issue invoices, file expenses, and reconcile data. Unlike consumer travel, business travel requires data and trusted transaction authority from both travelers and companies, including data ranging from personal loyalty preferences in history, all the way to company policy and approval rights. Amex GBT can already do this at scale globally, and we are architecting an agent-to-agent framework to deliver these capabilities. AI agents will also need access to the best marketplace in travel that sources content from all over the globe, negotiates bespoke content for savings, wires in company negotiated content, and aggregates it all seamlessly.

Using our centralized inventory is significantly more advantageous and cost-effective than agents doing independent scraping themselves. Finally, AI agents are only as good as the data they are trained on, and in our industry, our proprietary data is the gold standard. It includes, in part, millions of enterprise policy rules, hundreds of ecosystem partners, hundreds of supplier connections, and millions of transactions, emails, and hours of call recordings. Today, we're working in several ways to already bring this to life. Let me provide three examples. First, we're currently collaborating with a major technology company customer on integrating into their proprietary agentic platform to ensure managed travel experiences can be available seamlessly through existing and new enterprise channels. Even major technology customers are acknowledging the value Amex GBT provides by bringing capabilities like expert-driven cost savings, twenty-four seven duty of care, and policy compliance fully baked into their new AI workflows.

Second, as previously announced, we're collaborating with SAP Concur to bring our platform to full use across our joint customer base. In the flagship solution Complete by SAP Concur and Amex GBT, we are combining SAP's AI solution, Joule, with our travel capabilities to streamline travel and expense management through natural language conversations. This is an example of a leading enterprise application software player collaborating with Amex GBT on AI for travel. Finally, we're working to partner with AI native players to bring new experiences to our customers. In one example, we integrated an AI product for a large customer to create a new agentic channel. In summary, we have both proprietary and partner agentic experiences powered by the Amex GBT platform. These partners include a major technology company, one of the largest European software companies, and an AI native venture-funded new entrant.

In all of these cases, Amex GBT is providing extreme value with orchestration, workflows, and the marketplace, as well as acting as the trusted transaction authority on behalf of the company and its travelers. This is how we expect B2B travel to work in an increasingly agentic world, and we're fully prepared. Finally, I wanna highlight the significant cost reduction opportunity that AI presents. We have two primary levers for reducing operating cost. The first is reducing the need for human intervention. The progress we've made on digital self-service to date, coupled with the current path on AI solutions, gives us a clear roadmap to serve more travelers in digital channels, creating a better experience and reducing costs. We've already seen this in how our agent product is able to handle more self-service needs, and we're building these features into Complete and Neo now.

The second lever is ensuring our amazing travel counselors are as productive as possible in delivering exceptional service. To that end, we're building an AI agent assistance tool that will supercharge the ability of our travel counselors to serve travelers in a personalized, contextual, and efficient way. This is a win for both our travelers and Amex GBT. We believe the successful formula for managed travel is both high tech and high touch. While AI agents are increasingly capable, marrying that with experienced travel counselors remains core to our servicing strategy. Human agents will interact with fewer transactions over time, but when they do, it will be critical to revenue retention and growth. Even the savviest digital traveler cannot predict when any given trip may require some human help.

We're seeing this play out in real time as our traveler counselors work tirelessly to repatriate travelers from the Middle East. AI-driven efficiency gains aren't just an idea. They're having real-time meaningful effects on our P&L. AI is a primary driver for long-term operating leverage and margin expansion. We expect adjusted gross profit margin to increase by 150 to 200 basis points per annum over the next five years, reaching the high 60s by 2030, which represents material margin expansion versus where we are today. In summary, our strategy is very clear. We are developing AI to revolutionize the customer experience, our platform to power the agentic future in B2B travel, and using AI to accelerate cost reduction and margin expansion. I'd like to pass it on to Karen for the financial overview.

Karen Williams
CFO, American Express Global Business Travel

Thank you, Evan, and hello, everyone. Before we get into the specifics for the quarter, I want to reflect on the incredible progress we made in 2025. We delivered strong financial results, closed on the acquisition of CWT, and are continuing to make outstanding progress in terms of the integration of CWT into our business. The strength of our balance sheet provides us with opportunities to deploy capital in a disciplined, value-accretive manner. We generated over $100 million in free cash flow, refinanced our debt, and doubled our share repurchase authorization. We continue to deliver on our commitments and are confident in our outlook and the continued momentum in the business. Now let's turn back to the fourth quarter and the financial highlights, which show strong underlying growth and the addition of CWT into our results.

The corporate travel demand environment continued to accelerate in the fourth quarter, despite a short-term negative impact from the U.S. government shutdown. TTV, which reflects both volume and price, grew 45% to reach $10 billion. Transaction growth was 37%, driven by the contribution from CWT and growth in our core business as we continue to drive share gains and impressive customer retention. Revenue was up 34% to reach $792 million, Within this, travel revenue increased 36% in line with the transaction growth. Products and professional services revenue increased 27%, primarily driven by the acquisition of CWT and strong growth from our dedicated client revenues, as well as meetings and events. Excluding CWT, revenue grew 8% in the quarter.

Finally, Adjusted EBITDA grew 17% to reach $130 million, driven by the top-line performance and continued focus on driving productivity, operating leverage, and cost optimization. Let's now turn to margins. Last quarter, we introduced adjusted gross profit margin as a key metric, which we believe helps measure the success of our automation and AI initiatives. Adjusted gross profit margin was 60% for the full-year. Excluding CWT, full-year Adjusted EBITDA margin of 21% was up 144 basis points year-over-year and benefited from our continued focus on cost transformation. Our reported full-year Adjusted EBITDA of 20% and fourth quarter margins were down modestly.

Whilst the core business continued to deliver on productivity initiatives, the year-over-year reduction in margins is simply driven by the consolidation of CWT into our numbers, which pre-synergies operates at lower margins. Importantly, we project material expansion in both adjusted gross profit margin and adjusted EBITDA margin over the medium term as we deliver on the CWT synergies and the AI-powered cost transformation. Free cash flow for the full-year totaled $104 million, which when normalized for the CWT and M&A expenses, result in 40% free cash flow conversion as a percentage of adjusted EBITDA. Free cash flow in the fourth quarter declined year-over-year, again due to seasonality of working capital outflows and cash restructuring costs related to the CWT synergies. Finally, I'm incredibly proud of the strength of our balance sheet.

Our leverage ratio or net debt divided by last 12 months adjusted EBITDA is 1.9 x and remains below the midpoint of our target leverage ratio range even after funding the cash portion of the CWT acquisition. As a reminder, with the CWT acquisition, we have a clear path to a bottom-line synergy opportunity of $155 million, entirely driven by what we can control, which is cost. I am pleased to share we are tracking in line with the expectations we have previously shared. We expect to deliver $55 million of in-year synergies in 2026. To date, we have actioned $45 million of these and have confidence in realizing the full-year number. The actions taken to date primarily include workforce reductions, real estate consolidation, and vendor savings.

Now moving to our outlook, we are reiterating our guidance for the full-year 2026. We are guiding to full-year 2026 revenue of $3.235 billion-$3.295 billion, which reflects 19%-21% year-over-year growth and adjusted EBITDA of $615 million-$645 million, which reflects 16%-21% growth. As a reminder, there will be a temporary impact on our margins related to CWT. On a pro forma basis, including the full projected CWT synergies of $155 million, we would expect adjusted EBITDA of $715 million-$745 million. Looking at free cash flow, we expect to generate $125 million-$155 million.

Excluding the cash impact of restructuring and CWT integration, we would expect to generate $235 million-$265 million of underlying free cash flow, which represents a conversion rate similar to 2025 of approximately 40% of adjusted EBITDA at the midpoint. We expect an acceleration in our free cash flow conversion beyond this year as we drive growth, roll over the one-time items, and realize the CWT synergies. It's important to draw your attention to the expected shape of our performance in 2026 and cadence of our revenue and adjusted EBITDA outlook. Year-over-year growth rates will start out higher due to CWT until the acquisition anniversary during Q3 at the beginning of September. The seasonality of the combined business looks different in 2026 versus prior years due to CWT.

We expect to generate approximately 51% of full-year 2026 revenue in the first half of the year, with approximately 25% in Q1. We also expect to generate approximately 53% of full-year 2026 adjusted EBITDA in the first half of the year, with approximately 24% in Q1. This is driven by the phasing of the synergies benefits that ramp post Q1. From a free cash flow perspective, we expect Q1 free cash flow to be largely breakeven but accelerate in Q2 due to the phasing of the cost synergies and net working capital. We're providing more detail in the appendix on free cash flow and quarterly seasonality to help you guide your models. Now, it's important to note that our guidance does not include a prolonged impact from the Middle East conflict as it's too early to establish any facts.

For context, the region represents around 5% of revenue. Crisis management is a critical component to our value proposition, and I am incredibly proud of how our team is handling frontline servicing. I want to end by reiterating our capital allocation priorities and what we are doing to drive shareholder value. We are continuing to generate cash, which enables us to execute against our capital allocation priorities. Our first capital allocation priority is maintaining a strong balance sheet with a target leverage ratio of 1.5-2.5x. In January, we successfully refinanced our debt and achieved a 50 basis points reduction in our borrowing rate. Because of the productivity gains, we can invest in sustainable growth within our medium-term target CapEx envelope of approximately 4% of revenue. We are focused on discipline in our AI spend to drive profitable growth.

I would encourage you to think about this beyond the CapEx envelope as we think about the AI opportunity being a mix of build, partner, and buy. This leads nicely to our third priority, which is to pursue accretive, highly synergistic M&A. Because the CWT acquisition financing was primarily stock, we maintain a strong balance sheet to pursue additional M&A. Finally, given our leverage and cash position, we are in a position of strength to execute accretive share buybacks. Doubling our share buyback authorization from $300 million - $600 million in February reflects our confidence in the underlying strength of the business and our commitment to driving long-term shareholder value.

In total, we have returned $103 million to shareholders under the share buyback program to date, with $73 million in 2025 and an additional $30 million year-to-date through March 5, 2026. In summary, we delivered strong results to close out 2025 and expect even further momentum into 2026 and beyond. We look forward to sharing more at an investor day later this year. We can move into Q&A. Paul, Evan, and I are joined by Eric J. Bock, who is our Chief Legal Officer and Global Head of M&A. Operator, please go ahead and open the line.

Operator

Thank you. If you would like to ask a question, please press star followed by one on your telephone keypad. If you would like to withdraw your question, please press star followed by two. When preparing to ask your question, please ensure your device is unmuted locally. First question comes from Stephen Ju with UBS. Your line is open. Please go ahead.

Stephen Ju
Managing Director and Senior Equity Research Analyst, UBS

Hey, thank you. Evan, I wanted to dig in a little bit more on the underlying data you have disclosed on page 9 of the deck, particularly as it comes to how good AI has gotten and how quickly things may be improving for Egencia. 57% of chats are resolved without humans being involved. Can we get some idea of the slope of the improvement that you were driving here throughout 2025?

Stepping back and looking at things from a more, from a more bigger picture perspective, and I apologize, Paul, for, you know, asking you a question about, you know, running before walking, but, you know, how can we think about the benefits of what you're already seeing, from a customer service perspective, you know, that's already being demonstrated for Egencia, being rolled out to CWT also? Thank you.

Evan Konwiser
Chief Product and Strategy Officer, American Express Global Business Travel

Great. Thanks so much for the question, Stephen. Happy to take that. This is Evan. The 57% on deflection away from chat is largely based on non-transactional inquiries that we've had over the last year or two as we've deployed more tech into that channel. This year, with the full agentic launch of full transactions on hotel and air, and later, rail and ground, we're really bullish that that number is gonna go up pretty significantly. We also know the denominator will go up a lot as well as we get more travelers rather coming into this channel on all the different channels that we're gonna expose this to.

I think that both numerator and denominator are gonna change, but in ways that will start really showing up in the metrics across the business versus more of a help desk-style approach that we've had thus far. I think we're at a pivot point, and we'll be excited to share progress of that as that launch happens and we continue to evolve that channel.

Paul Abbott
CEO, American Express Global Business Travel

Stephen, maybe just add a couple of comments to the second part of your question. You're absolutely right. Egencia, you know, is the most advanced platform in terms of the AI capabilities and the self-serve capabilities. That sets the pace, and our objective is to get Complete and Neo up to the same levels of performance. And we have plans in place to do exactly that, including, of course, the CWT customers as they move across onto those solutions. I think in terms of the metrics to kind of keep an eye on, you asked about how you can expect this to trend going forward.

You know, if you look at our gross margin, you know, it's for Amex GBT standalone, gross margin was up 200 basis points over the last 12 months. Obviously, a lot of our AI and automation initiatives are driving that improvement in gross margin. Also, if you look at the percentage of self-serve, we've taken that up 300 basis points over the last 12 months. We were at about 80% of our transactions coming to digital channels. That's gone up to 83. These are some of the key metrics that, you know, we track to make sure that, you know, we are not just making progress, but also that progress is flowing through to deliverable impact in the P&L.

Stephen Ju
Managing Director and Senior Equity Research Analyst, UBS

Thank you.

We now turn to Duane Pfennigwerth with Evercore ISI. Your line is open. Please go ahead.

Jake Gunning
Senior Equity Research Associate, Evercore ISI

Hey, good morning. This is Jake Gunning on for Duane . Just first big picture, are there any regional and/or industry highlights you could share for the fourth quarter and early 2026, and any improvement in the government business as well?

Paul Abbott
CEO, American Express Global Business Travel

Yeah, obviously for Q4, we did see an impact on not just the government business, but more broadly in the U.S. from the U.S. government shutdown. You know, we were able to mitigate that impact and still deliver on our expectations for Q4 and full-year. Yes, we have seen an improvement now that the government shutdown is mostly resolved. Those volumes have improved into the first quarter. You know, obviously the big regional trend, stating the obvious, is the situation in the Middle East. You know, if you look at our demand through January and February, it was actually pretty solid across all the regions and for both months, very much tracking in line with our plan.

You know, obviously over the last week, we have seen an impact to volumes in the Middle East, as of course you would expect. Initially for us, that impact creates more demand because we have a lot of customers that are disrupted, a lot of changes and cancellations. In the short term, it actually results in an increase in transaction volumes. Obviously, you know, depending on how long the situation lasts, we are going to see some impact to forward bookings in the region. That's why Karen in her prepared remarks there sized the Middle East at approximately 5% of our revenues.

Obviously, at this point, it's far too early to be able to assess how long the situation may continue, but we're trying to be helpful in sizing the travel that where the Middle East is the point of origin or the final destination represents 5% of our revenues.

Jake Gunning
Senior Equity Research Associate, Evercore ISI

Okay, that's very helpful. Just on the SAP Complete partnership, are there any early stats or anecdotes you could speak to just indicate any early successes?

Evan Konwiser
Chief Product and Strategy Officer, American Express Global Business Travel

Yeah. We're having a great progress on rolling out our joint customers onto Complete. We have a rollout plan that started in fourth quarter and continues at pace, and we're expecting to have 90-95%+ of all of our joint customers using Complete this year. Early feedback has been positive, and you're gonna hear some new updates on our product launches at the SAP Concur Fusion Conference, which is next week in New Orleans. We're gonna be talking about the next step of our product joint release. Overall, the momentum is in full swing, and we're really excited to see that progress this year.

Jake Gunning
Senior Equity Research Associate, Evercore ISI

Great. Thank you.

As another reminder, if you'd like to ask a question, please press star one on your telephone keypad now. We now turn to Greg Parrish with Morgan Stanley. Your line is open. Please go ahead.

Greg Parrish
VP of Equity Research, Morgan Stanley

Hi. Good morning, everyone. Thanks for taking our question. To ask you about this, you know, the 150-200 basis points annually of gross profit margin expansion through 2030. It's quite robust. I know, Paul, you mentioned done that over the last 12 months. Maybe I just wanna kinda wanna unpack the drivers. It sounds like, at least from the slide, this is primarily AI efficiency savings. If you could kinda confirm that, and then should we expect this to start in 2027? I know 2026 is a little noisy here with the acquisition.

Sorry for perhaps a three-parter, but maybe just from a philosophical standpoint, I mean, do you expect clients will perhaps wanna share in some of these AI savings, or do you think you're in a really good position to have the benefits accrue to you? Thanks.

Karen Williams
CFO, American Express Global Business Travel

Okay. In terms of from a gross margin perspective, we're incredibly excited in terms of the runway ahead of us. Evan spoke to some of it, but ultimately, you know, as you look at the, particularly the cost of revenues and from a servicing perspective, we expect an opportunity from the demand deflection that he spoke about, but also from an agent productivity perspective. Yeah, feel great in terms of the momentum and that pathway as we look out over the short and medium term as to delivering against that. In terms of 2026 in particular, you know, you do see the combination in terms of the two organizations together. In terms of the underlying, we're continuing to see that progress and feel really good about it.

Paul Abbott
CEO, American Express Global Business Travel

Maybe I'll pick up on the last part of the question. I think one of the really positive things about our business model is that we already have a structure that incentivizes self-serve. We already have pricing structures with customers that are lower for, you know, 100% digital transaction, 100% touchless transaction. If you look back over the last four or five years, you know, we've taken our digital penetration from 60%- 83%, and that is one of the main tailwinds that has been driving our profit growth and our gross margin and our adjusted EBITDA margin expansion.

You know, I think we're very confident that the pricing structure that we have in place, you know, and because we've proven it over the last few years, yes, it does pass back savings to customers for self-serve transactions, but our operating costs are even lower. You know, that automation tailwind improves our profits and improves our margins. Frankly, AI is just going to supercharge that trend. We see it as being very, very positive for us.

Greg Parrish
VP of Equity Research, Morgan Stanley

Okay, great. Thanks for the color there. Maybe just a follow-up. Could we maybe just unpack the 8% growth excluding CWT in the quarter? Pretty strong number. I think FX was a little bit of a tailwind. Can you maybe break that down? Anything else to call out if air travel, GMN, sort of what was strong versus light in the quarter? Thanks.

Karen Williams
CFO, American Express Global Business Travel

We saw strong growth both in the SME and in the Global & Multinational from a sales perspective. We saw that continuation in the fourth quarter. Yes, there's probably a point from the FX. Also you will recall during the Q3 earnings call, we encouraged everyone to look at Q3 and Q4 together. See, we do typically see in that fourth quarter, just from a supplier perspective, some of the timing. We see the yields were much more akin to what we saw in Q2 at a higher level. That is also playing into it. Really confident in terms of that momentum that we saw in the underlying business, not only from the top line, but also the continuation in terms of that margin story and 210 basis points expansion.

Greg Parrish
VP of Equity Research, Morgan Stanley

Okay, thanks. I just wanted to confirm, you said FX was only 100 basis points?

Karen Williams
CFO, American Express Global Business Travel

At one point, yes.

Greg Parrish
VP of Equity Research, Morgan Stanley

Okay, I'll confirm on the follow-up with you there. Okay, thanks.

Operator

We have no further questions, so I'll hand back to Paul Abbott, CEO, for any final remarks.

Paul Abbott
CEO, American Express Global Business Travel

Great. Well, look, thank you very much to everyone for joining us. Also thank you to all of our teams around the world that contributed to such a successful year in 2025. Thanks very much.

Operator

Ladies and gentlemen, today's call is now concluded. We'd like to thank you for your participation. You may now disconnect your lines.
