RISKS
- Aengus Kelly stated, "if jet fuel prices persist at current levels for the next 3 to 6 months, it will place pressure on the airline industry," indicating potential negative momentum for customers.
- Aengus Kelly commented, "gain on sale will be lower and there may well be a limited bid for it in time" if there is a sustained downturn in flying, suggesting risk to asset sale margins.
- The company acknowledged, "we haven't agreed to anything material with the airlines" but indicated that extended fuel price elevation could lead to requests for support from airline customers.
SUMMARY
AerCap Holdings N.V. (AER 2.10%) achieved record profitability in the quarter, driven by gains on asset sales and elevated maintenance contributions, while maintaining a strong liquidity and below-target leverage. Management raised its full-year 2026 adjusted EPS outlook, announced a new share-repurchase program, and confirmed a robust sales pipeline exceeding prior asset sale projections. Strategic fleet management priorities emphasized new technology assets, with notable execution of a significant A320neo order and a high lease extension rate, showcasing effective customer engagement amid persistent global uncertainties.
- Aengus Kelly underscored that over 80% of AerCap's portfolio consists of new technology aircraft, reinforcing fleet risk mitigation.
- Peter Juhas reported the company’s secured debt to total assets at 9%, an all-time low for the business.
- The sales environment for aviation assets remained strong, with no material pullbacks or renegotiations in pipeline transactions as of quarter-end.
- Discussions around asset deployment into emerging industrial use cases, such as data center power generation, are ongoing, but management indicated unclear long-term demand and a lengthy sales cycle for aeroderivative conversions.
- Management stated that airline profit pressures typically do not directly impact AerCap’s lease profitability, as lease terms are contractually stable regardless of airline financial performance.
- The strategic barbell approach to portfolio construction has reduced exposure to mid-life and end-of-life risk for older technology assets.

Full Conference Call Transcript
Aengus Kelly: Thank you for joining us for our first quarter 2026 earnings call. I'll begin today with an overview of performance for the quarter before turning to discuss the market environment in light of current geopolitical events. I'll then touch on our outlook and strategic priorities for the remainder of the year before handing the call over to Pete to review the financials in more detail. Starting with performance. I am pleased to report that this was another record quarter of earnings for AerCap. The company generated GAAP net income of $818 million or $4.96 per share, and record adjusted net income of $889 million or $5.39 per share.
This represents an 18% GAAP return on equity or 19% adjusted return on equity for the quarter. Despite the macro backdrop, we continue to see robust demand for aviation assets, supported by persistent supply challenges and sustained consumer demand for air travel. The first quarter serves as a clear reminder and reinforcement of the long-term and durable nature of this business. Our multiyear fleet planning discussions with customers continued during the quarter, resulting in an 87% lease extension rate and the closing of 286 transactions. This included the signing of 202 lease agreements and the sale of 41 owned assets, generating sales revenue of $1.5 billion.
Importantly, 57% of the lease agreements were signed in March, suggesting little change in airline behavior despite the geopolitical uncertainties. Given our strong results in the first quarter, including the repurchase of $745 million of our outstanding shares, we are increasing our full year adjusted EPS guidance to $14.50 per share, not including any additional gains on sale. I am also pleased to announce today the authorization of a new $1 billion share repurchase program. Now turning to the broader market environment. We continue to see strong demand for our assets despite recent geopolitical events.
That being said, if jet fuel prices persist at current levels for the next 3 to 6 months, it will place pressure on the airline industry. The extent of the impact on individual airlines will vary depending on factors such as region, business model, balance sheet strength and fuel hedging practices. To date, the industry has been able to pass on a significant portion of higher fuel bills to consumers. Looking beyond 6 months, elevated fuel costs will pressure airline profitability and place greater emphasis on airlines' balance sheet resilience and financial flexibility. Over time this could contribute to an acceleration in the retirement of older technology aircraft.
So this is not a dynamic we are seeing play out just yet. As we know, airline fleet planning decisions span multiyear horizon, and carriers typically do not make long-term fleet decisions in response to a few months of market volatility. In the scenario in which fuel costs remain elevated beyond 6 months, we would expect to see additional growth opportunities emerge for AerCap. In particular, it is likely that we'd see increased sale-leaseback opportunities as airlines look to fund growth while preserving cash and prioritizing liquidity. For context, the global order book remains heavily skewed to airlines with just 4 airlines having a combined order book larger than that of the entire lessor community.
In both the near and longer-term scenarios, AerCap is well positioned to support our customers while continuing to maintain a disciplined approach to capital deployment, execution and risk management. Against this backdrop, we entered the second quarter with a below-target leverage ratio of 2.1x net debt to equity, $21 billion of liquidity and more than $3 billion of excess capital. This positions us well to execute our strategy, balancing organic growth and share repurchases while maintaining flexibility for future opportunistic investments. Our continued investment in new technology assets, including the 110 aircraft added to our backlog in the first quarter, reflects our disciplined approach to capital allocation.
We are targeting assets with strong demand fundamentals and attractive long-term economics, consistent with our positive outlook for the aviation sector. With respect to our 100 aircraft order in March, our infrastructure, industrial capability and scale enabled us to execute this very complex transaction with speed while supporting key business partners in the process. By leveraging our leadership in the engine leasing space, we were able to agree attractive terms, including a delivery stream that starts in 2028. This order not only underscores our unique market positioning, but it enhances the quality of our portfolio, aligns with our constructive outlook on the sector and ultimately supports long-term value creation.
In closing, this was another strong quarter for AerCap, reflecting the durability of our business model, the quality of our asset portfolio and the disciplined execution of our strategy. Despite a mixed operating environment for our customers, underlying demand for aviation assets remains strong. We enter this period from a position of strength, supported by robust earnings, low leverage, high liquidity. We'll remain focused on prudent capital allocation, supporting our customers where appropriate and investing in assets that we believe will continue delivering attractive long-term value for our shareholders. With that, I'll now hand the call over to Pete to review the financials in more detail.
Peter Juhas: Thanks, Gus. Good morning, everyone. Our GAAP net income for the first quarter was $818 million or $4.96 per share. The impact of purchase accounting adjustments was $84 million for the quarter or $0.51 per share. That includes lease premium amortization of $26 million, maintenance rights amortization of $37 million related to maintenance revenue and maintenance rights amortization of $21 million related to leasing expenses. The net tax effect of these purchase accounting adjustments was $13 million or $0.08 per share. As a result, our adjusted net income for the first quarter was a record $889 million or $5.39 per share. And that represents an adjusted ROE of 19.4%, also a record.
I'll briefly go through the main drivers that affected our results. Basic lease rents were $1.682 billion, slightly lower compared to last quarter, and that's primarily due to aircraft sales as well as downtime on aircraft that we took back from Spirit Airlines. Maintenance revenues remained elevated this quarter at $190 million. Our net maintenance contribution, which is maintenance revenue less leasing expenses, after taking into account purchase accounting adjustments, was $138 million this quarter. That's higher than usual due to the timing of maintenance revenue, transition expenses and claims. We expect net maintenance contribution to remain elevated through the first half of this year before trending back towards more normal levels in the second half.
Net gain on sale of assets was $291 million for the quarter. The sales environment continued to be strong and we sold 41 of our owned assets for total sales revenue of $1.5 billion. That resulted in an unlevered gain on sale margin of 24% for the quarter, which is equivalent to a multiple of 1.9x book value. As of March 31, we had $899 million worth of assets held for sale. Interest expense was $467 million for the first quarter. Leasing expenses were $110 million, which is a significant decrease from the fourth quarter when we recognized the majority of the restructuring costs related to the Spirit Airlines bankruptcy.
Our income tax expense for the first quarter was $139 million, reflecting an effective tax rate of 15.5%. Turning to liquidity. Our liquidity position continues to be very strong. As of March 31, our total sources of liquidity were approximately $21 billion. That includes just under $1.5 billion of cash and $10 billion of revolvers and other committed facilities, as well as estimated sales and operating cash flow. Our sources-to-uses coverage ratio was 2x, which reflects excess cash coverage of around $10 billion. Our leverage ratio at the end of the quarter was 2.1:1, the same as last quarter. And our operating cash flow was $1.4 billion for the quarter.
Our secured debt to total assets ratio was 9%, which is an all-time low and a decrease from 10% last quarter. Our average cost of debt was 4.1%, the same as last quarter. And in terms of share repurchases, during the first quarter, we bought back 5.4 million shares for a total of $745 million. And today, we've announced a new $1 billion share repurchase program. Given the strong performance in the first quarter, we're raising our full year 2026 adjusted EPS guidance to approximately $14.50. We're increasing our estimate of EPS, excluding gains on sale, to approximately $13, which is the top end of our previous range.
And we're also including the $1.50 of gains on sale from the first quarter. However, we have not included any gains on sale for the remainder of the year. As it relates to asset sales, our initial guidance for asset sales this year was between $2 billion and $3 billion. Given the large sales volume in the first quarter and the significant held-for-sale balance at the end of March, at this point, we expect that sales will be over $3 billion for the full year 2026. And I expect those sales to be weighted towards the first half of this year. In closing, despite recent geopolitical events and ongoing macroeconomic challenges, AerCap has continued to perform very strongly.
During the first quarter, we generated record adjusted EPS of $5.39 and record adjusted ROE of over 19%. The addition of 110 Airbus A320neo aircraft to our order book this quarter at attractive terms and a delivery stream starting in 2028 illustrates AerCap's ability to use the power of our platform, including our leadership in engine leasing, to invest in the growth of our business. Our recent Airbus order together with the new share repurchase program we announced today as well as our increase in full year guidance all indicate our confidence in the value of AerCap today and into the future. And with that, operator, we can open up the call for Q&A.
Operator: [Operator Instructions] We'll go first to Ron Epstein with Bank of America.
Ronald Epstein: Gus, thanks for the commentary around the current environment out there. When you think about potentially the duration of what's going on in the Middle East, when would you expect it, or not, to start impacting residual values of older planes? And when you guys think about that, how should we think about that?
Aengus Kelly: Ron, well, it's important to look at what's actually happening on the ground in terms of flights. So the average daily number of flights in April of 2025 was 102,833. In April 2026, the average number of flights is 102,131. So Ron, I give that number because the amount of daily flights, the reduction year-on-year for the same period is 0.068 of 1% (sic) [ 0.68 of 1% ]. So, so far, we have seen a de minimis impact. It's not to say we won't see more of an impact over the rest of the year if fuel remains elevated. But to date, the number of flights that were down is a de minimis amount.
Now it takes airlines years to adjust a fleet plan. And any aircraft we have on lease are on lease for a long period of time. So I would say it would be quite a significant period of time before we were to see older-technology aircraft being replaced or exiting a fleet. An airline cannot just exit the aircraft type. As it pertains to AerCap at any rate, we have the greatest concentration of new technology aircraft in the world of any major airline or leasing company at over 80%. So it will take some time, Ron.
Ronald Epstein: Got it. And then maybe one follow-on. Just kind of thinking out loud here, if I were an airline and I wanted to protect my balance sheet, but I still wanted to bring on new airplanes, why wouldn't I just go to you? And I mean, I'm not trying to throw you a softball here, but it would seem like in the current environment, that leasing an airplane might be a more attractive option to an airline that might not have wanted to do that before. So maybe in sort of a weird way, could this be a stimulus for you guys? Or am I just thinking about that wrong?
Aengus Kelly: No. It certainly -- I mean, look, there's no doubt that if higher fuel prices continue, you will see a reduced financial flexibility that the airlines have. And bear in mind, as I said in my prepared comments, the OEMs are over-indexed to airlines, the weaker credits, of their customer base. And 4 airlines alone make up more than the entire order book of the leasing industry. So I would imagine that if this were to continue, there will be opportunity in sale leasebacks as you referenced there, Ron.
Operator: Our next question comes from Jamie Baker with JPMorgan.
Jamie Baker: So Gus, kind of building on that, specific to used aircraft sales that -- transactions that you're already working on in the pipeline, since the start of the war, have any aircraft sales fallen through or settled at lower-than-hoped-for economics? Given that presumably some portion of your customer base is happy to take a pause on growth, and of course, fuel efficiency has probably never been more important than today.
Aengus Kelly: Well, fuel efficiency is definitely important, you're absolutely right, Jamie. But why I highlighted in my prepared comments that 57% of our transactions closed in March when the war had started, we have not seen anyone pull out of a sale yet or try to renegotiate one. While you're right, fuel is important, there still is a tremendous demand for CFM products, in particular, because of the scarcity of those engines in the market. So as of yet, we haven't seen anybody pull back. And I ask that question every day here at the trading team, and there's no sign of it.
Jamie Baker: Excellent. And then specific to the Middle Eastern airlines, at what duration of elevated fuel do we need to start questioning whether twin-aisle demand specifically will continue to exceed supply? I know you spoke to what the world might look like after 6 months sort of in general, but my question is more specific to the Middle East and the demand for widebodies.
Aengus Kelly: That's a fair point, Jamie. And when I referenced the daily number of reduction in flights, of course, they're heavily concentrated in the Middle East on widebodies. Now there are winners in this too. I'll give you an example. We had 2 A350s coming back from a customer in China. Those aircraft, I was with the CEO of a major European carrier at the end of March when the war was in full swing, and he just said to me, "Just tell the team, call them, tell them we're taking them, no debate. We want them as fast as possible." I give that as an anecdote because there are winners here too.
For the last 15 years, major European and other Asian carriers have obviously had a very difficult time with the Gulf carriers. Now is their chance, those carriers that can fly around the Gulf and connect Europe to the Far East, they are doing well now. They are all looking for lift. We thought we had another package of widebodies that we could take out of a customer 3 weeks ago. Within a week, we had quite a number of bids lined up. The customer actually then decided to hold on to the widebody aircraft.
There's no doubt, though, that over a period of time for the Middle Eastern carriers -- but I would never write off the Middle Eastern carriers, they will be back, of course. I think it would have to take a very significant period of time before the airlines that are owned by the State of Qatar, Abu Dhabi and Kuwait and Dubai would let orders go. I do think, to be fair though, what you might see is a greater reliance on the leasing industry to finance those aircraft if and when they come. But I would not see them being canceled.
Operator: We'll go next to Moshe Orenbuch with TD Cowen.
Moshe Orenbuch: Great. I was just wondering if you could kind of talk a little bit, given that your capital levels have been stable despite all of the buyback, how do you think about deployment of that and what opportunities are out there? I mean in the deck, you mentioned kind of $5 billion of expected CapEx. But are there ways to kind of enhance that? And how else should we think about that in the balance of '26?
Aengus Kelly: Well, as you've seen year after year after year, we find accretive opportunities that are additive to shareholder value. And I would back AerCap to do the same again this year. As you've seen, due to the unique capabilities the business has, we were able to solve the issues for our business partners in CFM and for an airline partner in Frontier, be able to take aircraft and engines out of Frontier, put them into our engine leasing pool.
And as part of that, because we did that, that freed up capacity in the Airbus production line, and we were able to exercise options and get slots that no one else in the world could get access to, as I referenced, that they start in 2028. I would imagine that as the year goes on, we will find other opportunities, either because of the unique [ capabilities ] I just outlined or due to, if we do see more pressure on airline balance sheet, I think we'll see some opportunities. But every year after year, we've managed to find asset growth opportunities.
And then, of course, look, we also believe that the cheapest aircraft in the world, as I said before, are available on the New York Stock Exchange under the ticker AER. And we are leaning into that as well. And certainly, at any time of weakness in the stock price, we will lean into that.
Moshe Orenbuch: Great. And just as a quick follow-up, I apologize, I've been bouncing between calls this morning, did you give any update on the kind of the maintenance and return to service on the Spirit aircraft?
Peter Juhas: We didn't specifically give any update on that. I mean. As I mentioned before, we're looking at kind of latter part of this year where the first of those may come back into service. So they're going into the shop as planned. And then we'll look to see some revenue coming off those late this year.
Operator: We'll go next to Catherine O'Brien with Goldman Sachs.
Catherine O'Brien: Gus, a follow-up on your answer to Moshe on AerCap's track record of sourcing unique growth opportunities over the last couple of years. Could you just -- I mean, I know you're not going to give us exact numbers, but could you provide some color on how the acquisition costs or projected returns on these transactions compare to what you would have seen by placing a direct OEM order or acquiring assets via sale-leaseback RFP?
Aengus Kelly: Well, of course. Look, we don't mind how we spend our money as long as we make money. And we make money, we make it at a level that's comparable to the alternatives we have in the business, for example, buying back stock, et cetera. But look, what I would say, Catherine, is I'd have to work hard. I mean I can be lazy and just roll up to an OEM at the airshows and place an order that starts delivering in 2032 and finishes in 2038 and get crushed on escalation and take massive placement risk for an environment I've no idea about.
But leaving that alternative to the side for AerCap, which we won't do, we work very hard, and the infrastructure and scale that we have has enabled us to continually generate opportunities. And you've seen not just that. You've seen the results of those opportunities in the P&L today and in previous quarters, and you'll see it in quarters to come.
Catherine O'Brien: That's great. And then I know last quarter you said you were investigating aeroderivatives for data center power generation. If you've got any updated thoughts, that would be great to hear too. But we're really wondering if you're already seeing elevated demand for your aircraft or engines from those already pursuing converting engines for this use?
Aengus Kelly: The discussions have continued. And those discussions are with data center builders. And there's 2 components for the guys who build data centers. There's the actual shed itself, as they say. And then there's the interior, the complex engineering behind the interior build of the generator. We've spoken to the OEMs and we've spoken to others who will be involved in the converting of an engine into a mobile gas-powered unit. Now we've also spoken to end users. And in the end users, there's different stripes. There's guys who are property developers, that build data centers and then try and lease out the space.
And then of course, there's a much stronger credit quality, which would be very large corporate entities, such as hyperscalers and others. What is clear is that there is significant demand today and probably in the near term. At the moment, it's less clear where the demand is in the long term. It may well be very strong. The sales cycle appears to be long as well. That being said, it's something we are continuing to investigate and also to get a full handle on the cost and the R&D. That's going on with the 2 companies who could actually convert the engines for us. But we have to get firm costs and an idea of true long-term demand.
And then the final point, of course, if there are other entities out there, and there are 2, that are looking to buy commercial aerospace engines and put them into aeroderivatives, if that does become a significant market, then of course, we will participate indirectly in that way. But as yet, we don't see that.
Operator: We'll go next to Terry Ma with Barclays.
Terry Ma: Maybe just starting with the CFM engine deal. Can you maybe just talk about the lease rates or the returns on those engines compared to what they were kind of generating when they were on the original aircraft?
Peter Juhas: Sure, Terry. The lease rates on those are basically the same. We're basically getting the same amount as we were on the aircraft as a whole.
Terry Ma: Great. Okay. And then if we were to think about the net spread margin going forward and just kind of like the moving pieces, it doesn't sound like there's much downtime on the engines. But then you have Spirit aircraft coming online and you do have a large bond maturing. Like what's the kind of trajectory or cadence of the net spread margin?
Peter Juhas: Sure. So as I mentioned, a couple of quarters ago, we expected to have the net spread be pretty consistent over the next few quarters. So it was 8% this quarter, same as third quarter, same as fourth quarter. I think that will probably continue for another couple of quarters. And then later in the year, we should see some expansion, as I mentioned. Some of that is going to be driven by some of those assets that are currently on the ground coming back online. We'll have some more freighters delivering late in the year, so that's part of it as well. So I'd look for some uplift in the second half of the year.
Terry Ma: Got it. That's helpful. And then if we were to look at ROE, you guys kind of generated an impressive 19% adjusted ROE this quarter, at a time when the business is well under your leverage ratio. Is there kind of like a way to think about normalized ROE through the cycle once you kind of normalize that leverage?
Peter Juhas: Yes. Well, if we look at the long term, like, say, from 2007 to now, on average, we have generated ROEs of about 950 basis points above the 5-year treasury. So that's how we've looked at it over the long term. If you look at the last few years, so each year we've been between 14% and 15% roughly for the last few years. And this quarter obviously was quite high with the 19.5%. That was driven by -- somewhat by the higher maintenance contribution, by the higher gains on sale and those type of things. But nonetheless, we would expect to continue running at very high levels. Now as you note, correctly, we're at low leverage now.
I think over time, we're going to normalize that. It's going to go back to 2.5x, something like that. And that should be a positive for ROE, right, as we deploy more of that capital.
Aengus Kelly: I think, Terry, the key point for me, as I've always said to you, is that this business generates extremely stable returns, and does through thick and thin. As Pete said, we're going back 18 years in those numbers. And these are GAAP numbers. They're not adjusted. In the short term, sure, you can adjust numbers. But in the long run, it has to be GAAP. And the GAAP ROE of this business, as Pete said, is 9.5% above the 5-year treasury for that period, for 19-odd years. There's very few of any companies in our industry, be it industrial or otherwise, that could match those ROEs.
And when we look forward, as I said, I've always said, that the business through thick and thin should be in and around 8% to 10% above the risk-free rate, the 5-year treasury.
Operator: We'll take our next question from Kristine Liwag with Morgan Stanley.
Kristine Liwag: The Airbus A320neo family orders that you were able to get, I was surprised that there were available slots in 2028. I was wondering if you could talk more about the terms and how this opportunity came about. I thought that the aircraft was more sold out beyond 2028. And then also that the -- you mentioned in your prepared remarks that it was in fairly attractive terms. Any details that you could provide would be appreciated.
Aengus Kelly: Sure, Kristine. And you are right, I think if you walked up to Toulouse for the airshow and ask for an order, they'd probably start in 2033, 2032. Now why was AerCap different, and why is it consistently different? Well, it's to do with what we can do for key suppliers and key business partners. In this instance, because we're the largest engine leasing business in the world, we knew there was a shortage of engines in the global business, globally for all, shortage of CFM LEAP engines. We knew that a key business partner of ours, Frontier, would like to reduce capacity. We had the infrastructure, and it's very important to be able to move rapidly.
Given enough time, others might be able to do it over a couple of years. We were able to get the engines out of Frontier within a matter of months, start -- within a matter of weeks, start redelivering those engines, getting them into our lease pool and getting them out there to support the in-service fleet of Airbus Neo equipment. This meant that there was less pressure on the production line to divert engines to the spare engine pool and more slots would be available then to produce new aircraft. So we're helping the airframer, the engine OEM and our airline customer. No other leasing company in the world can do that.
That enabled those slots to free up, and we had options that we could exercise with Airbus and we exercised them. And that's why our 100-plus aircraft, the vast majority of them, will have delivered by the time I'd say any other leasing company could begin an order stream.
Kristine Liwag: Great. Super helpful context. And Gus, maybe this is more of an opportunistic question, but with the breadth of your portfolio, the quality of your balance sheet, it seems like you're really poised to take advantage financially of some of these incrementally distressed situations. So if oil prices were to extend beyond the 6 months in an elevated way, can you talk about if you do start seeing distressed airlines there, is there a way for you to size incremental opportunities or things that you could do to increase your return? Because you seem to be in a position to do that. You've consistently done it.
And any sort of color you could provide there and how you're poised for that, again, would be appreciated.
Aengus Kelly: Yes, Kristine. We are, of course, at the lowest leverage we've been at with a very large balance sheet, with $21 billion of liquidity. That all being said, I certainly don't wish for the current situation to drag on any longer than is humanly possible. We certainly would not like to see it drag on for the rest of the year, and hopefully, it won't. No doubt, if that was the case, there would be pressure on some airlines. But would that just be a few airlines in difficulty? Probably. And would we be able to cope with that? Yes. But to the other side, I suspect there would be opportunity.
Because as I mentioned earlier on, the OEM order books are heavily overweight the airline industry. Four airlines alone have a greater order book than the entire leasing industry. So to me, the OEM order book is over-indexed to the weaker credit of the airline industry on average than to the stronger credit of the lessor. So I would imagine if we do continue to see these levels of elevated fuel prices, that there may well be opportunities.
Operator: Our next question comes from Arren Cyganovich with Truist Securities.
Arren Cyganovich: This balance of a net negative for airlines of higher oil prices potentially for an extended period of time being a net positive for you, I totally understand it. But it also seems a little, I don't know, backwards. Maybe talk a little bit about how lease rates would trend in those kind of scenarios. I'm assuming the gain on sales would probably come down quite a bit. What are some of the negative impacts that you would see that would balance out some of those positives?
Aengus Kelly: Yes, you're right. And that's why I certainly wouldn't want this to -- I want this current fuel issue to resolve itself as fast as possible. And you're right, in an example where there is significant stress on airlines over a period of time, of course, what you're going to see is reduced level of flying. But that will primarily affect older technology assets, of which, as I mentioned earlier on, AerCap has less than 20% in our portfolio, and most of them are on lease to fairly strong credit. So they could get retired over time.
But you're right that it would be more -- if we were selling those assets, of course, the gain on sale will be lower and there may well be a limited bid for it in time. That being said, those things can't happen overnight. As it relates to leasing rates, yes, of course, if there is a reduction -- a significant reduction in flying, there will be some impact on lease rates. But I want to go back to what we said about the ROE of this business. We're going back to 2007 and the stability of the returns of this business have been proven through thick and thin.
And I would also say that we have found those opportunities that are accretive in the long term as well when we do have periods of difficulty.
Operator: We'll go next to Shannon Doherty with Deutsche Bank.
Shannon Doherty: First and foremost, have any of your airline customers reached out seeking concessions of any form given the cost pressure from higher fuel?
Aengus Kelly: As yet, we haven't agreed to anything material with the airlines. I'm sure that if this continues over the course of the next 6 months, we'll have guys coming in and asking us for some assistance. But to me, I would think that would be very much on a case-by-case basis as we have in the past. But I want to go back to what I said at the start of the prepared comments just to give you an overview of the entire industry. At the moment, the number of flights is down less than 1%. That could creep up, of course, I'm not saying it wouldn't. There will be pressure on airline balance sheet over a period of time.
But right now, fuel represents generally 30% of an airline's cost base. Airlines, for the most part, are able to pass on a significant percentage of that, between 40% and 50% of it, a lot of them are being able to pass on in terms of cost -- in terms of fare increases. And then of course, there's other steps airlines will take, which will be to reduce flying, voluntary leave for staff, pilots, for flight crew, et cetera. And so they will be able to mitigate a fair amount of this themselves. It will have a significant impact on airline profitability. But from our standpoint, very key again, why are we so stable?
Our profits are the same whether or not an airline makes $1 billion or breaks even. And that's a very different analysis, of course, for the airline. But I would think like everything we see with this industry, this too will pass.
Shannon Doherty: Great. Maybe for my second, Gus, can you break down any changes in demand that you're seeing for new versus old technology aircraft? And what is the historical lag in change in demand to the impact on market values and lease rates?
Aengus Kelly: Look, as yet, it's far too early to say an impact on market value and lease rates. Every transaction that we have had in the hopper, airlines are still pushing forward. There's one transaction where there's a change in management of the airline, and that's being put on pause. That was a handshake that happened, but that wasn't to do with the fuel crisis, I would say. So overall, as yet, we haven't seen it. But there's no doubt that I think if this were to last through the end of the year, the 6 months I referenced, and maybe a little bit before that, that you would see a reduction in the bid potentially for older technology assets.
But that's not a part of the market that we're particularly exposed to. Many of you over the different investor presentations we've shown will have seen how we look at our sunset approach to the portfolio, to get out of those older tech assets. And as I said, those older tech assets that we have, most of them are on long-term leases as well. So they couldn't be returned anytime soon. But you're right, I suppose, in terms of if you're looking at gains on sale for those assets, that may well be a bit different. But it's not a huge part of our portfolio.
Operator: We'll go next to Chris Stathoulopoulos with SIG.
Christopher Stathoulopoulos: So I have one question. Gus, I'm going to frame it, just want to hear your thoughts on how you're thinking about, I guess, risk management here in a scenario where the business as a whole, managing the portfolio, et cetera, but in a scenario where fuel is higher for longer, perhaps we see as some of the airlines are pointing to demand elasticity or destruction and then some inflationary pressures on the consumer and consumer staples. I thought it was interesting how you mentioned around older technology retiring in a higher for longer fuel scenario. So maybe you could talk about that within what is unique to AerCap, this barbell approach.
But then holistically, portfolio risk, asset values and lease rates. I think it's important here as we consider potential outcomes if fuel is 3, 6 months or 12 months higher and this does then start to metastasize, if you will, into the broader economy. What is AerCap's approach to managing the portfolio with this older and new? And how are you thinking around things like asset values and lease rates?
Aengus Kelly: Sure. Well, like any challenge, you don't think about it when the challenge arrives. You have to be thinking about it for 10 years before. And you rightly referenced our barbell approach to the portfolio. And those of you who have seen those slides, and we show them time and again, is that from 2012 onwards, we took the view that we want to invest in new technology assets or older versions of older technology if there was something of great value. But generally, only buy new tech assets. And that meant avoiding orders for 737s, A320s, A330s and 777s. Because ultimately, those aircraft will be replaced by the newer technology.
And if you were to buy a 25-year asset in 2014 or 2015, it needs to be in service until 2039 or 2040. And so our view was let's just make sure we're out of those assets. And particularly, we never ever buy any young variants of those assets. And that's what we've been saying for many years on these calls, that the key is to always own assets that the remaining economic life can be consumed. So I have no concern about owning a 777 today that's 20 years of age. For sure, they will be in demand for the next 5 years.
I certainly wouldn't want to own one that's 10 or 11 years old because I doubt it will be in demand for 15 years of age. But it was tempting 10 years ago to buy those assets, and many did. So from AerCap's perspective, as I said, the way to look at our company and the portfolio risk is to say, well, show us the percentage that is old and new tech. So we're 81% new, 19% previous, older tech. And then look at the age of that older tech. And with us, you'll see it's very old and it's, for the most part, nearly all on lease.
So I'm not concerned about our carrying values in that regard for either old or new tech.
Operator: There are no other questions at this time.
Aengus Kelly: Well, thank you very much, everybody, and we look forward to speaking to you in 3 months' time, if not before.
Operator: This does conclude today's call. Thank you for your presentation. You may now disconnect.
