Vertical Aerospace Ltd. (EVTL) 2025 Q1 法說會逐字稿

Thank you for standing by. My name is Carly, and I will be your conference operator today. At this time, I would like to welcome everyone to the Vertical Aerospace Q1 2025 earnings conference call. All lines have been placed on mute to prevent any background noise.

(Operator Instructions)

Thank you. I would now like to turn the call over to Charlotte. Please go ahead.

Hello everybody, good morning. I'm Charlotte Cowley, Director of Strategic Finance at Vertical Aerospace, and I'm delighted to welcome you to our Q1 2025 earnings call today.

Before we get started, I would like to remind you that during today's call, we'll be making forward-looking statements. These statements involve risks and uncertainties that may cause actual results to differ materially from those contemplated by the forward-looking statements. Any forward-looking statements we make on this call are based on assumptions as of today, and we undertake no obligation to update these statements as a result of new information or future events.

We've posted an accompanying slide deck to the investor relations section of our website at investors.verticalaerospace.com, which contains information and cautionary warnings on forward-looking statements. For a more complete discussion about these risks and uncertainties, we've also filed a 6-K with the SEC this morning.

Now I would like to hand you over to Stuart.

Good morning, good afternoon, good evening everyone.

Thank you for joining us and welcome to our Q1 call. I'm Stuart Simpson, the CEO of Vertical Aerospace. I'm going to cover three things. Firstly, to remind you why we believe we are set to succeed. Secondly, I'll update you on our progress during the quarter. And thirdly, to give you some color around the big announcement we made yesterday of our hybrid program, a hybrid aircraft with a range of 1,000 miles.

This represents a huge additional market opportunity for us across defense and wider commercial operations, all incremental to our base flight plan 2030 that has already been communicated.

Given it is all about having the right capacity for moving people and things. This hybrid gives us an incredible opportunity because we have the largest dimensions of how tilt rotor appears and this puts us in a brilliant position to be able to dominate this space.

Then Doctor Limhi Somerville, our Director of Engineering, will discuss our battery and technical details and progress made on hybrid to date. I'll then touch on where we close the quarter in terms of financials before we open the call for questions.

In November, we launched our Flight Path 2030 business strategy, setting a clear roadmap to lead the eVTOL sector by the end of the decade. We established transparent financial and operating metrics for '25, '28, 2030 and beyond, including a credible timetable for certification.

As you will hear today, we've already made meaningful progress towards achieving these targets, further strengthening our belief that vertical is going to be a winner in the sector. We have a best in class aircraft in terms of safety, capacity for both people and luggage and comfort.

We are the only eVTOL player positioned to serve the full global market by certifying to the highest aviation standards. We are moving at pace through the certification process with all phases of piloted flight tests on track to be completed in 2025.

We have a highly capital efficient approach with a clear path to profitability, spending approximately 75% less than our peers for a superior product. And we have a lean and highly experienced team that has certified 30 plus aircraft and propulsion systems.

Turning to our progress since the start of the year, it's been a quarter of significant momentum and I'm pleased to share several key developments as we advance our mission to bring electric flight to customers. Starting with our test program, where we have achieved a number of important technical milestones, building on our completion of thrust borne testing earlier this year.

Most notably, we delivered record breaking piloted high-speed taxi tests with our VX4 demonstrator. These tests validated key systems under real world conditions and are a major step towards our next piloted wingborne flight, which we anticipate starting in Q2. Completing piloted Wingborne will be an incredibly significant moment for us.

Not only will this make us in the top two OEMs in the industry for piloted flight tests, but as a UK based aerospace business, where unlike other jurisdictions, the burden of safety is shared with the regulator.

Having a joint liability with the company. As such, each phase of testing can only occur with specific approvals from the UK Civil Aviation Authority. As you can imagine, we are working incredibly closely with them to achieve this next step.

To this end, we have submitted around 20,000 pages of documentation to the CAA to extend our permit to fly to encompass piloted wingborne flight.

The CAA's approval of this test will serve as a strong signal of their confidence in the safety, design and ability of the VX4 aircraft to operate in public airspace. We expect to advance to this stage over the next few months.

I would like to address one topic that has arisen in recent days. We are aware a claim was made that the UK CAA will be aligning their certification standards to those of the FAA. As you would expect, we have very frequent interaction with the CAA as our home regulator, both at the working level and with the most senior levels of its executive management team.

Since that claim was made, the CAA's management have confirmed the following to us in writing. The CAA's position on certification of EVTOL aircraft is set out transparently in its certification of eVTOL aircraft publication available on its website.

This document confirms the CAA will use SC‑VTOL as the certification basis for eVTOL aircraft in the UK. SC‑VTOL includes the safety requirement that these aircraft demonstrate a catastrophic failure rate of 10 to the minus 9.

There has been no change to this published certification standard for eVTOLs. The CAA is working with other authorities, including both the FAA and EASA towards international harmonization of eVTOL certification.

Based on this written confirmation, it is clear to us that the UK safety objectives remain unchanged. Any such change would require due process, which includes a public consultation.

As we have said for several years, we welcome attempts between global regulators to harmonize certification standards, but we do not believe this should or will be at the expense of passenger safety. We firmly believe that passengers will expect these aircraft to be as safe as commercial airliners, and we know our customers share that view.

Safety is non-negotiable. We remain confident that by certifying our aircraft to the highest commercial aircraft safety standards globally, we will be uniquely positioned in the industry with the only offering capable of serving all jurisdictions around the world.

This brings me to another important point. These aircraft are being designed to carry passengers and will be certified as such, which is why we maintain it is absolutely critical to conduct a piloted test with one of our experienced test pilots in the cockpit under real world conditions.

All the data we have from previous flight tests, hours of modeling, and numerous simulations give us total confidence in the capability of our aircraft and the success of our upcoming piloted wingborne flight test.

In terms of our operational goals for 2025, we're on track to complete all phases of our piloted flight test program by the end of the year, including transition flight, the final stage of testing, giving us even more confidence in our certification timeline.

The team's discipline and execution continue to prove that we have the right approach to certification and development, and that the VX4 is one of the most advanced eVTOL aircraft under development today.

And as we do all our development with a pilot on board to ensure that we get not just digital feedback and data but information from our test pilot. Real world insight from some of the world's most experienced test pilots. This ensures the final aircraft will meet our customer expectations for safety, comfort and quality.

Importantly, as we continue to progress on our priorities, we are on track to double our airborne test fleet capabilities this year as we complete the assembly of the identical twin prototype aircraft, which has already been moved to our flight test center at Cotswolds Airport for finalization of the assembly.

This will also unlock further learnings as we install the hybrid powertrain that we referred to earlier in the call. Moving on to partnerships, we have made significant progress both commercially and strategically.

Just last week we finalized a key decision to advance our production plans. Specifically, we formalized and expanded our partnership with Honeywell to deliver flight controls and aircraft management systems for our certification and production aircraft.

In addition, we have chosen Honeywell for our inceptors to make VX4 easier and safer for pilots to fly. This partnership and the use of Honeywell's leading systems will unlock the efficiencies and speed necessary for Vertical to lead the industry in bringing the safest and most scalable product to market. It is a contract of some significant value worth approximately a billion dollars over the next 10 years.

Honeywell has been and will continue to be a fantastic partner. I'm delighted we've forged such a close working relationship over the last six years and can see this lasting long into the future. We are also supporting the acceleration of a global wide industry charging infrastructure.

By adopting the combined charging standard, CCS, for the VX4, the same as beta and Archer. We believe a unified approach to charging is essential for the industry to be successfully globally. It will help ensure seamless integration for OEMs, operators and infrastructure providers while reducing costs and accelerating the adoption of electric aviation.

Using the CCS fast charging standard will allow verticals VX4 to achieve quick turnaround times, including rapid battery charging and conditioning for shuttle operations. Ultimately, our adoption of CCS will enable immediate interoperability with all CCS chargers of this standard, including beta's growing network.

Finally, we've announced the addition of three new directors to our board, building on the steps we took earlier in the year, with Domhnal Slattery rejoining as chair and Eamon Brennan joining as a board advisor.

The three new directors are Kris Haber, JK Brown, and Carsten Stendevad. With these appointments, we continue to strengthen our governance and strategic leadership with deep, complementary experiences, particularly in industrial scale-up, and all three have phenomenal capital markets expertise.

Kris, amongst other roles, has been the COO of Investorp and Advent International. JK was a founding partner at Oxy Capital Management and Carsten is currently Co-Chief Investment Officer for Sustainable Investing at Bridgewater Associates and a Board Advisor to GIC.

Their combined insights and expertise will be invaluable as we enter our next phase of development.

I will hand over to Dr. Limhi Somerville, our director of engineering, to provide some detail on our success in battery development, a team he has been leading for the last 6 years. It is the strength of the innovation and capability within this team that has enabled us to unveil details of our well-advanced hybrid program yesterday.

It is tremendously exciting and unlocks new additional multi-billion dollar market opportunities for us. This aircraft will have a range of over 1,000 miles, opening up additional use cases, most specifically within defense, cargo, emergency services, and long-range commercial missions where it is all about moving people and things. As I said before, our airframe is of a greater scale than peers, so we feel we are well placed to dominate in this space.

All represent upside opportunities to the targets we shared in Flight Path 2030. The hybrid powertrain will be integrated into our next generation VX4 variant with flight testing planned to start next year.

Within Flight Path 2030, it is worth remembering that our battery systems will be replaced more frequently than the airframe itself, one times to two times a year, depending on how our customers fly and use the aircraft.

Something akin to the razor razor blade model. his means into the 2030s, vertical's revenues will reach a 50/50 split of aircraft to battery with a very healthy gross margin of greater than 40% from the battery.

In addition, there are most likely Second Life applications such as Marine or CTOL, for example, which will provide an additional source of revenue for the business, again not included in the base case flight Plan 2030.

I'm incredibly proud to say that Limhi is due to present to the Royal Society of London later this month. The Royal Society is the UK's National Academy of Sciences, and Lim Hye has been invited to give a presentation to this prestigious institution on Vertical's battery capability and how Vertical is set to lead the industry.

That presentation will highlight the incredible promise of our proprietary battery technology.

Over to you, Limhi.

Thanks, Stuart. Hello, my name is Doctor Lim High Somerville. I've been at Vertical Aerospace for 6 years and last year became Director of Engineering. I used to lead our powertrain and before that battery teams, which is what I will speak to today.

Some information about me before I start, I've previously worked on battery systems at Jaguar Land Rover and at Argonne National Laboratory in Chicago before that.

I also spent 5 years chairing the Urukai Electrical Subgroup 1 of Working Group 112, leading on many of the existing certification standards accepted by EASA as part of the SC‑VTOL means of compliance for battery and electrical systems certification.

So what I will share with you today, first, our battery system, team capabilities and manufacturing approach are world class. Second, we have evidence of this, having now achieved significant milestones that de-risk our path to a category enhanced certification. And third, we're open for business, ready to sell our advanced battery systems to the world.

Finally, I will touch on the last 18 months of development on our hybrid program and give you an insight on our quiet confidence in this area.

Let's fly through it now. One, world-class battery teams, systems, capabilities and manufacturing. Our lithium ion battery systems are the cornerstone of our aircraft backed by more than six years of development.

Here's what sets our battery apart. The team is comprised of a perfect blend of aerospace, automotive, and control electronics experience. This has not happened by chance and gives us the right blend of performance, focus, and certification rigor.

Energy power, density, and performance. Our battery packs achieve a 4:1 cell to pack ratio, delivering more than 200 watt hours per kilogram dependent on cell choice, including electronics, controls, sensors, and wiring.

Cycle life and durability, our cells deliver more than 800 full cycle equivalents with approximately 90% capacity retention, ensuring lower maintenance costs and reliable performance over the aircraft's life.

Cost efficiency for the life of the vehicle, our battery systems will be replaced much more frequently than the airframe. This means over time battery costs drive a much higher proportion of the long-term high margin revenue.

Our battery systems have been designed to allow replacement of the cells with minimal cost, fast charging and cooling. Through millions of cell module and full pack cycle hours in proprietary testing rigs, our system can be optimized to charge fast, getting the balance between turnaround time, lifetime, and performance precisely how the customer wants it.

Highest certification standards. We have designed our system from the very beginning to comply with the EASA and the CAAs stringent SC‑VTOL regulations, which is the highest levels of safety in aviation.

Software integration, we utilize a proprietary battery management and control system that is designed to the highest assurance level, achieving sensor redundancy, software optimization and excellent prediction of remaining power.

Manufacturing Our business uses a capital li and efficient operating model pre-certification, whilst ensuring we have the intellectual know-how and capability to scale up when we're ready.

I've seen firsthand the risks associated with early industrialization. Not only does it often consume millions in purchase of equipment that is unsuitable, but ultimately, it can also force poor decisions on the design as the now legacy manufacturing equipment is considered non-negotiable design hard points.

two developments de-risking EASA SC‑VTOL certification. Our advancements significantly de-risk our path to the CAA and EASA SC‑VTOL certification targeted for 2028. The SCVTOL framework sets rigorous and clear safety and performance standards that we can show compliance against with our technology.

The key developments include, we're on our 8th iteration of battery design since Vertical aerospace for this capability in-house.

We have been using our own batteries to power the VX-4 prototype's flight test for years, and we are on the 11th battery.

Our latest design is the safest, lightest, and most capable yet, and we haven't finished with 2 more development cycles in the next 12 months before locking down the final battery for our production aircraft.

Let me give you an example of the benefits coming from each iteration. Between Aircraft one and our current prototype, we save more than 100 kg, that's 10% of our battery system mass, whilst also improving mechanical, thermal, drop, and power performance.

We've been developing the technology in our battery systems for years. Our first propagation and drop tested battery pack was in 2020, with both EASA and the CAA in attendance. On April 9th of this year, we passed the 15.2 m full pack drop test, which is comparable to the fuel tank drop test on a traditional rotorcraft. To be clear, we passed this same drop test on our battery system in 2020, 5 years ago. According to the requirements defined by EASA within SC‑VTOL, we continue to optimize the design to reduce mass significantly and then pass this test again this year. Passing that test is comparatively easy. Passing that test with all functionality present at the energy and power density we have is tough, and we've done it.

Battery system propagation testing. We've completed nearly 200 propagation tests to date across multiple different battery iterations, aiming to not only meet the EASA SC‑VTOL means of Compliance 3 standard, but also understand our performance against them.

On April 29th of this year, we passed our latest full-scale thermal runaway propagation on a sub pack from our VX4 aircraft. We have two further optimization rounds to go as we continue to test and optimize the battery system further and ensure we understand and can pass all of the nuanced edge conditions that are possible.

What this means is that in line with the SAS SC‑VTOL requirements, if a battery fire were to occur on one of our vehicles in flight, we'd be able to continue safe flight and landing either to the destination or to an alternative landing port with full maneuverability of the aircraft, disembark from the aircraft, and all of this whilst ensuring the complete safety of the occupants and the aircraft itself.

Whilst there cannot be any guarantees on timeline to certify, we've taken industry leading certification standards, applied them rigorously, and iterated multiple times until we pass them using a battery that is exceptionally high in energy and power for the mass at a cost that makes the business profitable in the future.

We're open for business. We're selling our battery systems and new opportunities. One of our most significant investments of vertical has been on the development of our hardware, software, and mechanical battery systems. We believe we have one of, if not the best battery teams in the world, and we're now ready to tell the world about what they've achieved.

Because they've achieved it. e've used this exact same approach of technology development on battery as we have on our hybrid program. Iterate quietly, make progress on the difficult technological work to show it works, and at a performance point we think is commercially viable, and then share that with the world.

For the last 18 months, we've been working on a hybrid powertrain system.

Our aircraft has a segregated electrical architecture for redundancy, and to comply with the category enhanced requirement, that means we can continue safe flight and landing after any single failure.

This capability allows us to take off and land in all-electric configuration, cruise with the turbine operating when noise is less impactful and charging all the batteries if it's needed, and then land again in an all-electric configuration.

Obviously, this significantly impacts the range capability of our vehicle, as Stuart has just made clear. The first hybrid generation used a combustion engine and the second generation will be a gas turbine. We are so far developed in this that we are planning to incorporate it into our 3rd prototype aircraft to start flight testing in 2026.

I really want to be clear on the technical significance of what we have done so far. We have proven the capability of a single engine to provide power to a multiple electrically independent systems, including under edge case failure conditions.

This is one of the most technically complex parts of development and critical to being able to operate under a category enhanced type certificate. Now we have done that, we will incorporate it onto the prototype aircraft for flight testing coupled with our best in class battery systems and start testing in 2026.

This is also where our larger aircraft and cabin is beneficial because the volumetric limitations on a smaller airframe would stop us from making such a change without consuming the available cabin space and thus invalidating its value or requiring a completely new or significant change to the type certificate.

In our case, the range payload benefits of hybrid can be gained by consuming the luggage compartment and a minor encroachment on available cabin space, which is very spacious in an all-electric configuration. Of course, in unpiloted configurations, there would be no need to encroach on the available volume at all. I hope you found that informative. I'll now hand back to Stuart.

Thank you, Lim high.

As you've heard, we're advancing across every dimension, technology, commercial traction, and strategic positioning.

We remain focused on achieving our certification goals, progressing towards production and building long-term value for our shareholders.

In terms of our finances, we continue to demonstrate sector leading capital efficiency while investing appropriately for the continuing successful execution of our plans.

Net cash used in operating activities for Q1 2025 was approximately $30 million, and our guidance for the spend for the year as a whole is unchanged at approximately $110 to $125 million.

We closed the quarter with approximately $90 million cash and cash equivalent on hand.

As I highlighted on the full year call in March, each time we report, there will be a non-cash financing movement relating to our outstanding convertible loan notes.

This is highly volatile, driven by a calculation relative to the prevailing stock price. For Q1, this was a GBP396 million credit to the P&L and just to be clear, non-cash.

Just starting to wrap up, to remind you again of what we've set out to achieve operationally this year, you can see the points on the slide and we are on track to achieve all of them. And in addition, we have announced our new hybrid aircraft.

Before turning over to Q&A, I would like to remind you why we believe we are set to become one of the winners in the sector.

Incredible progress to date, a clear plan for '25 and beyond, with a clear route to certification in 2028. We have a best in class aircraft set to be certified at the highest safety standards to be able to support our customers across all geographies with a capacity for both luggage and passengers that is unmatched in the sector.

We have announced our advanced hybrid program, creating an aircraft with over 1,000 miles capability and opening up further multi-billion dollar opportunities. And we have an incredibly focused and highly capital efficient business model.

We focus on where we as vertical can make a real difference and then working with world class partners for efficiency and effectiveness. Thank you again for joining us today, we'll now open the line for questions.

At this time I will now turn the call over to Charlotte for questions.

Thank you. So we just thought we would raise one question that we got quite a few, people asking us yesterday on the back of the hybrid. So, this is to ask, Stuart, what is the impact on our cash spend and our cash burn going forward given the hybrid announcement yesterday?

No, thank you for the question. I think the first point to note is we've been working on this, hybrid powertrain for some 18 months. So all of that development that Lim high and the team have done was within the cash spend that we've talked about over the prior years. So we've done a huge amount of hard work in terms of getting the battery to talk to the motor, to talk to our EPUs.

All of that was in the cash envelope we've already had, demonstrating the incredible capital efficiency by being really focused on what we're doing.

So, as of today, no change to our guidance for this year. The cash spend for this year remains projected to be in the range of $110 million to $125 million.

Thanks, Stuart. So back over to you operator for polling for the Q&A, but we just wanted to address that as, we had a lot of incoming yesterday.

Thank you. (Operator Instructions)

Our first question comes from Savanthi Syth with Raymond James.

Hey, good afternoon. Sorry, I was wondering if I could ask, a little bit more on the certification front of the high bid retail, just is that a supplemental type certification, or would you have to start from scratch with EASA, and just along that if you kind of go down the path of defense applications, is there kind of a pathway to revenue generation before EASA certification?

So morning Savvy, thank you for the question. In terms of the hybrid product, it goes within our current airframe, so everything that we're doing there, we're on track with. And to be clear, nothing that we've announced on a hybrid distracts us from the core underlying electric BX4 aircraft, which is well on track for certification in 2028.

The hybrid will be certified as a separate aircraft, likely in and around the same time as the electric VX4, maybe slightly delayed because we're, as we haven't fitted in an aircraft yet. That being said, we will have a full scale piloted hybrid aircraft flying in Q2 next year.

It's incredibly excitement, exciting moment for us. In terms of, earlier revenue opportunities, we've been in deep discussions for. Several months with various potential customers, we can't really say any more than that and in terms of short-term changes to cash flow guidance, etc. So I'm sorry I can't go into detail on that, but thank you for the question Savvy.

Just to clarify, does defense have different certification requirements? Is that a fair assumption?

It does, depending on what the use cases are, yes. So there are potentially ways that this could be certified earlier, but we don't want to get into that at the minute, as I say, we're just incredibly excited to put this, aircraft out there, having been working on it for 18 months.

Makes sense. I realized that was a multi-part question, so I'll get back on the cue. Thanks.

No problem, thanks, Abby.

Your next question comes from Austin Moeller with Canaccord.

Hi, good morning. Just my first question here. So will the hybrid powertrain be integrated into one of the two existing airframes that you have, to conduct testing next year, or would there be a third airframe that you would be, integrating that into?

So morning Austin, thank you for the question. The hybrid will be going into the airframe that is well under construction at the minute, we've done a huge amount of the build work on that. We'll be tidying that up over the next three months, four months.

First of all, we'll be flying it as a. All electric aircraft, as I've mentioned before, we continue to drive the VX4 program to completion and certification in 2028. We will then retrofit the hybrid powertrain to that aircraft, and we'll have that flying in Q2 next year, Q2 2026. Hopefully that clarifies it, Austin.

Okay, that's helpful. And just to follow-up, so on the EAS a certification process, I think it mentions in the shareholder letter that, you expect to complete the flight test program this year, but I presumably there would be additional flight testing with additional aircraft units in the, out years here as you work towards your type certificate, or how should we be thinking about that?

Yeah, good question, Austin. What we're referring to there is going through the four phases of flight test expansion. We're going into Wingborne over the next couple of months, an incredible moment for us as a company, as there's joint liability with our regulator, and when we do Wingborne, we will be into public airspace, so it's a huge vote of confidence in us that.

Our aircraft will be flying in public airspace. It's basically a huge sign from the regulator that they believe we're on the right track and are happy to say the aircraft is safe to fly in public airspace. Later this year we'll then do the full transition, so incredibly excited about that.

That completes the four phases. We then will have two aircraft capable of repeating that multiple times to generate more and more test information that we feed into our models and to continue to develop our understanding of the VX4.

So hopefully that explains it. We will definitely be doing a lot more flying.

Excellent. Looking forward to it.

Thank you for the clarification.

Thanks, Austin.

Your next question comes from Jesse Sobelson with D. Boral Capital.

Hey everyone, thanks for taking my questions here. The first one I had was just, it's a little bit of just a detail oriented item here. With the testing on the fully electric aircraft, I just want to make sure we're 100%, fully understanding expectations for wingborne testing when you say it's in 2Q '25. Is this phase beginning in this quarter or is it expected to be completed in this quarter?

It will be beginning in this quarter, and as I just said, this is an incredible moment for us because we have a huge high bar to climb to be able to fly in public airspace. So it really does set us apart, it's an incredible moment for the company when that happens, and we are absolutely targeting that in Q2 2025.

Great, thank you very much for the clarification there, and then, I did want to touch upon, the hybrid, announcement. I think it's very interesting, with respect to commercial opportunities, how does the introduction of a hybrid electric propulsion system expand verticals capabilities from maybe focusing just on urban air mobility to expanding into regional air mobility? Is it possible that airlines could be purchasing this for use with short regional flights in the future?

Yeah, great question, Jesse. The capability of this aircraft is utterly transformational. It'll have a range of over 1,000 miles. It will have a payload capability of over 1,100 kg, and this is all because we have the best airframe in the industry. We always knew from day one that defense and longer range commercial opportunities would be opened up by a hybrid powertrain.

So we've had this working for a long time in the knowledge that this would come along and be an opportunity. And of course having the biggest airframe means we will be the most capable in this sector, more people and more things over a longer distance.

Great, thanks for taking my questions.

Yeah, thanks, Jesse.

Your next question comes from Laura Li with Deutsche Bank.

Hey, thank you for taking my question and, congrats on all the progress. So my question is about the battery business that you talk about. So how will that business model look like? Is that like a direct sales or like as a service and also any color on the timeline, like when you expect it to start generating revenue?

Laura, thank you, that's a great question. I'll do a short intro and then hand it over to Lim H.

You know the battery, our battery capability led by Lim H and now by the the wider team is incredible. I'm I'm so proud to be able to work with these people, what they've done is incredible. We see huge opportunity here as you look forward, both selling our battery and powertrain capabilities.

But also the Second Life, so when we take the batteries off the aircraft, off the VX4, then opening up a new opportunity to sell those again for different applications, whether that's marine, sea toll, etc. With that limb high maybe if you want to add a little bit of color commentary around that.

Yeah, thanks, Stuart, and thanks Laura for the question. So, really it's predominantly been around making progress against the battery system and trying to prove that we could technically do the things that we, Both said and and we were required in terms of the technology itself, so.

That's kind of the bit that we've hit, we've been contacted for years now with respect to battery systems of individuals interested and we've rejected a number of them because of the focus that we're putting both on that and the right opportunities were not coming along and I suppose this is us sort of informing everyone that, we will start accepting some of those, we will start looking into some of those now, and certainly in the coming weeks and months ahead.

I'd expect to hear more about that precisely because we were getting really good. Good values, we're getting, we're seeing great performance, and we're kind of hitting lots of points that are quite difficult and, problematic to be able to hit at a really good energy and power density, so. Hopefully that answers your question or at least gives some color that Stuart was referring to.

Yeah, thanks Lin hi, and Laura, just to remind you, every airframe that we sell, there is an underlying amazing battery business here for us. Every airframe we sell will get one to two batteries a year that are greater than 40% margin. So within a few years after launch, we'll be 50% revenue from batteries, 50% from the airframe. And it's a fantastic ongoing business, the razor razor blade model. So really exciting part for us.

Okay, gotcha. Yeah, I appreciate the color.

Thanks, Laura.

Your next question comes from Amit Dayal with H. C. Wainwright.

Thank you. Good morning, everyone. Great presentation today, with all the color, this with respect to certification in other jurisdictions, how should we think about what is taking place, for the US market, the EU, and other opportunities or other jurisdictions you are.

Pursuing.

Great, morning Amex, thanks for the question. In terms of certification, as our home regulator is the CAA. They are linked to, EASA in terms of the standard they've set, they're both very clear. They're using the SCVTOL certification basis at 10-9. The same as a large passenger carrying jet, we believe this is what the market wants. We believe this is what customers want and safety should be nonnegotiable. Now that is the most challenging standard in the industry.

We know how to hit it. We can hit it. Because it's a little bit higher than others, we will be working with all the regulators around the world to passport the aircraft into those markets. We're extremely excited about getting to the US, getting to the Middle East, getting to Asia, huge opportunities for us there, but in terms of certification, we'll do it in the UK working hand in hand with them as a home regulator at the same standard as EASA who we're also working incredibly closely with.

Hopefully that gives a bit of a feel for it, Hammett.

Yes, no, I appreciate that.

Thank you. Just one more for me, how are you building, sort of customer relationships at this point? I know it's still early, given that you're testing and going through all the certification stuff, but in terms of facing customers and showing them the product, etc. What kind of feedback are you getting? Any color on that side of the process would be helpful.

Thank you.

Yeah, really good question. I think this is something that set us apart as a business. We have an incredible order book, we're very proud to have American Airlines, Bristol, Babcock, Japan, Cacao, Gaul, I mean phenomenal customer base all across the world, and that's underpinned by our certification standard at 10-9.

In terms of how we manage the relationships, we've been listening and working with our customers from day one, in terms of what the aircraft capabilities need to be, and that's one of the reasons we have the best airframe. We start with 6 full scale business class passengers and really importantly, they can take luggage on it. So we launch with 4 people plus 120 kg,130 kg of luggage capacity. No one else can do this. We can quickly expand within the same airframe, no big certification hurdle to six passengers.

And how we maintain this relationship, twice a year we bring our customers to us in Bristol. They spend 234 days with us twice a year and we walk through, okay, how the aircraft's evolving, get them to meet the team, but most importantly, understand their use cases, how they want to deploy it and help them model out how we bring this to market in a way that's incredibly successful and profitable for them, and we can provide them with the aircraft that they need. So we're very proud of all our customers.

Thank you, Stuart. That's on us.

Your next question comes from David Zazula with Barclays.

Hey, good afternoon and thanks for taking my question.

Please, can I just follow-up on that? I think there had been an announcement from a, significant, UK airline that they were considering looking at another platform. I mean, is that something you're hearing from any of your other customers that they're looking around, or do you feel like you have the home market, pretty well under control?

Yeah, David, great question. I think one of the things I inherited when I took over as CEO was an order book that had been closed for a couple of years. Now it's one of the things we are going to open up that order book this year, as we deepen and expand our customer base over the coming, months and years.

So we will absolutely be having conversations, not just in the UK but all across the world as we look to further bolster that order book as we're getting closer to certification, we've got a confirmed date in terms of when we're going to certify, we know we can hit it. Now is a great time to really start opening up that order book again across the world. So hopefully that gives you a bit of color commentary without going into specifics, David.

That that is helpful for lim. We've heard a characterization of battery as kind of a choice between erring more on the side of safety, erring more on the side of being aggressive and towards performance. 200 watt hours per kilogram seems like you are trying to push performance. So I guess one, would you Agree that that is a fair characterization of the choices that suppliers are making on the battery side and where do you fall, if so, on that sort of spectrum in your battery design.

So David, I'll just take that and then hand to Lim H. Just to be clear, safety is paramount for us, non-negotiable, so we are doing everything, and I think we are the world leaders in this. What Lin and the team have done is remarkable, and we will have a battery certified to 10-9. Absolutely the best in the industry, so we must put that at the front of it, I think with that li I if you want to comment on David's other points about power density etc.

Yeah, thanks, Stuart, and thanks for the question, David. .

Fundamentally, to come back to Stuart's point, that really is the goal always is we have to be able to show that we're safe and if you take EASA as an example, they gave an excellent talk a couple of years ago of basically what looked like a battery onion as they went through the different layers of safety that they expect in order to be able to clarify that at the voters' conference.

And that's essentially the same goal that we've gone from, gone for. But to give you an example, when we went from our aircraft one to our aircraft two, the only thing that changed was actually, or the primary thing that changed, not the only thing that changed, but the primary thing that saved us mass was an optimization of the plastics that we were using.

And so we were pretty good before but not great, and then we optimized and we went through the plastics that we were using, both the selection, material selection, and essentially mechanically how it's structured. And so that's where this, the unit comes from. It doesn't impact safety in that respect, in fact, the safety got better because we moved more towards self-extinguishing materials and plastics and so.

From that respect, to come back to Stuart's point, that really is the baseline, there's no way around that, you've got to achieve that. Everything that we're doing is achieving that whilst trying to optimize and make make us, better in terms of performance. Hopefully that answers your question.

Super helpful. If I could just squeeze one more in, Stuart, I mean, I didn't see anything. Maybe I missed it on, EPU and anything to announce there or any preview you can give us on how you're thinking about the EPU.

So nothing we can announce other than the current ones we have are doing an incredible job, they're outperforming on every dimension. We've got a handful of options as we look to move forward through the certification and put in place a.

Certification contract and production contract, so nothing to announce as yet, but we're really confident in that space and we've got incredible EPUs on our current aircraft.

Awesome thanks so much. I'll hop back in the queue.

There are no further questions at this time. I'll now turn the call back over to Stuart for closing remarks.

Thank you, first of all, thanks everyone for joining, really appreciate you taking the time. This has been an incredible past few months for Vertical, absolutely transformational for the business, starting in December where we restructured the balance sheet.

From that point on, raising the $90 million in January, the flight test progress this year has been incredible, and we are so close to wingborne flying, as we said, we'll be doing that within the next couple of months, it's certainly in Q2. Absolutely fantastic and will really set us apart versus other people because we're doing this under the auspices of a regulator that is validating our aircraft, to be safe to fly in public airspace.

We've signed our certification and production contract with Honeywell, we have strengthened our board and really importantly, the announcement of the hybrid. We've been working on this for some time. We are so proud to be able to bring it to market today, a range of 1,000 miles, capacity of 1,100 kg, low noise signature, it really does open.

Tremendous opportunity for us across defense and other commercial markets, so I don't think we've ever been better placed for success, so thanks again for joining, really appreciate all the questions. I look forward to updating you, hopefully, pretty quickly on some further news, so thank you very much.

Ladies and gentlemen, that concludes today's call. Thank you all for joining. You may now [disconnect].
