Overview

Our vision is to transform how the world moves. We are a global aerospace and technology company that is pioneering electric aviation, focused on designing, manufacturing and selling a zero operating emission electric vertical takeoff and landing (“eVTOL”) aircraft for use in the advanced air mobility (“AAM”) market, using cutting edge technology from the aerospace, automotive and energy industries.

Founded in 2016, we draw on deep aerospace and automotive expertise. We designed, built and flew two sub-scale prototype eVTOL aircraft in 2018 and 2019. We are currently developing, and are progressing towards the certification of, our flagship eVTOL, Valo (previously known as the VX4). Our first full-scale prototype successfully concluded its remote thrustborne flight test campaign in August 2023.

Our second, more advanced, full-scale prototype commenced flight tests in July 2024. In January 2025, we took another significant step in our testing program by successfully completing our first piloted thrustborne flight maneuvers. The milestone was achieved after we received approval from the United Kingdom’s Civil Aviation Authority (“CAA”) to expand our Permit to Fly, enabling us to progress from piloted thrustborne hover to piloted thrustborne low-speed flight maneuvers at altitude.

Thrustborne flights, with lift generated by the propellers, are designed to assess the aircraft’s stability, battery efficiency, control characteristics, aerodynamics, structural and dynamic loads and performance across different speeds, enabling further assessment of how the aircraft behaves under real-world flight conditions. In February 2025, we completed the piloted thrustborne testing phase.

In May 2025, we commenced Phase 3 of our flight test program, completing what we understand to be the first-ever wingborne flight of a winged electric vertical take-off and landing aircraft in European open airspace, where the aircraft took-off, flew and landed like a conventional aircraft, with lift generated by the wing. On July 16, 2025, following Flight Conditions and Permit to Fly approvals from the CAA, the prototype flew from our Flight Test Centre at Cotswold Airport to the Royal International Air Tattoo (“RIAT”) at RAF Fairford, a Royal Air Force station which is used by the United States Airforce. In September 2025, we announced the conclusion of Phase 3 wingborne testing, with the aircraft performing as modeled in the simulator, validating both the design and ease of handling.

In December 2025, we completed the assembly of our third full-scale prototype, identical to the second, and the aircraft will begin flight testing following commissioning. Both our second, and third prototypes include much of our strategic partners’ technology that we plan to incorporate into our final certification aircraft. In addition, we also expect to have five flying and two static aircraft, for certification purposes only, built prior to the end of 2027.

We are targeting Valo to be capable of transporting a pilot and up to six passengers, traveling distances of up to 100 miles, and achieving cruise speeds of 150 mph, while producing minimal noise and zero operating emissions. Valo is being designed around existing certifiable technology, as well as certain novel technology such as the batteries and propellers which we are designing and developing in-house. Collectively, our experienced team has previously certified and supported the development of over 30 aircraft and propulsion systems around the world. We are currently one of the only eVTOL designers and original equipment manufacturers (“OEMs”) actively pursuing certification from the CAA and the European Union Aviation

Safety Agency (“EASA”) with a winged vehicle. We aim to have our aircraft certified to safety targets the same as those to which large commercial airliners are subject, based on standards that are multitudes times safer than those applicable to small single engine helicopters. EASA and the CAA have also agreed how they will collaborate on the certification of Vertical’s Valo, under the technical implementation procedures agreed as part of the UK’s withdrawal from the European Union. While both regulators have been working closely already, this sets the foundations for their certification experts to apply common standards and work together towards concurrent certification and validation of Valo by both authorities. In 2023, the CAA announced its intention to adopt EASA’s Means of Compliance to SC-VTOL, the standards against which European and UK manufacturers design eVTOLs. In 2025, the CAA announced its eVTOL Delivery Model which sets out a regulatory framework to facilitate commercial eVTOL flights in the UK by the end of 2028. By achieving certification of our Valo eVTOL aircraft from the CAA and EASA, we expect to leverage the work done with our home regulator to have the certification validated by other regulators where we intend to operate, including the United States Federal Aviation Authority (the “FAA”), Brazil’s National Civil Aviation Agency (“ANAC”) and Japan Civil Aviation Bureau (“JCAB”).

In March 2023, the CAA issued us with an eVTOL DOA, the scope of which was expanded in July 2024, enabling our engineers to sign-off compliance of an expanding range of technical areas, including additional aspects of flight control, avionics and electrical systems. By enhancing our capacity to carry out certification activities, we expect to streamline the overall certification process. UK and European aerospace companies cannot hold a type certificate, necessary for entry into service, without being granted a DOA. The DOA authorizes us to conduct design activities and issue design approvals within the DOA’s scope of approval. In 2025, we maintained our DOA after our first 24-month audit.

We have forged strong relationships with industry-leading players to develop the various components of our aircraft. For instance, we are co-developing our flight controls systems with Honeywell, to unlock maximum performance with safe and simple to operate controls, reducing pilot workload and thereby reducing pilot training and operating costs. We are partnering with Aciturri Aerostructures, which has long-established experience in composite aerostructure development and manufacturing of major airframe components to supply the entire airframe, including the wing, empennage, pylons and fuselage for Valo. Combined, these features provide a flexible design to address different markets and a scalable design to facilitate manufacturing. We collaborate with Dassault, which provides and help us customize its 3Dx Platform software, in which we design, configure and develop the Digital Twin of our aircraft. Our proprietary battery system utilizes small format cylindrical cells to provide high power density while at the same time, being low cost and highly reliable, as well as utilizing safety features to ensure safety across all operations. We have selected Evolito to supply us with a type-certified lightweight, efficient electric motors, with high-integrity DAL-A power electronics, integrated into a single electric engine (an “EPU”), expected to provide the extended range, high performance and built-in redundancy required for Valo’s entry into service. Our advanced propeller system uses four tilting propellers at the front of the aircraft and four stowable propellers at the rear to enable high efficiency in all phases of flight and support a vehicle noise signature that we believe will be less than 70dBA in hover, the same as low-level city traffic, and less than 50dBA in cruise, which is likely to be unnoticeable in an urban environment. We are working with Syensqo (formerly Solvay), one of the world’s leading chemical and advanced materials companies, to ensure that our materials and composites are high quality and sustainably sourced. Syensqo’s advanced materials are to be integrated across the entire airframe, providing the lightweight strength, structural efficiency and durability required for the high-cycle operations of electric vertical flight. We are also working together with CAE, a market leader in flight simulation and training, to develop a best-in-class training program. CAE will be the exclusive training device provider, tailoring the high-fidelity, next-generation flight simulation training device for the aircraft. We believe these relationships will allow us to provide superior products at scale, while maintaining a lean cost structure and taking advantage of both internal and external research and development synergies.

In May 2025, we announced a complementary hybrid-electric aircraft. This aircraft complements the eVTOL aircraft by maintaining the same aircraft architecture. The hybrid electric is intended to extend the payload and range capability of the pure eVTOL platform to carry up to 1,100 kilograms and travel 1,000+ miles, enabling new potential applications in defense, logistics and commercial sectors including air ambulance services, which require longer range and higher payload than current eVTOL platforms can deliver. Our ability to develop industry-leading aircraft is rooted in our team’s depth of talent, experience and culture. Our senior team includes technical experts handpicked from the aerospace and advanced automotive

industries. Combined the team have certified over 30 aircraft and propulsion units. The complementary skill sets of our leadership team are critical to the success of the aircraft designs and our business.

In November 2024, we launched Flightpath 2030, our strategy for market leadership before the end of the decade through embedding a pioneering culture, redefining aerospace best practice, intelligent partnering and being safety obsessed. Flightpath 2030 sets out defined goals for Vertical to achieve by 2030, including certain operating goals — among other things: the number of aircraft targeted to be delivered to our customers, an annual production rate target, certifying the all-electric Valo aircraft in 2028, maintaining a zero accident rate — as well as and certain financial goals. In September 2025, reflecting our subsequent progress and learnings, we announced a number of revised or new operational and financial goals.

We are developing a sophisticated eVTOL ecosystem that allows us to focus on providing a high quality experience. Our in-house expertise, together with our industry-leading partners, cover design, certification, assembly and manufacture, pilot experience, end-user experience and base platform performance. We aim to be one of the leading eVTOL aircraft OEMs, selling globally certified eVTOL aircraft to a variety of customers, including, commercial airlines, aircraft leasing companies, business aviation, tourism groups, mobility platforms and existing helicopter operators as well as new operators in the AAM market, providing both OEM sales and aftermarket services to our customers. We also believe there is a potential market to provide OEM sales to a variety of industries beyond traditional airline and helicopter customers, such as tourism, where there is an opportunity to replace existing transportation options like minibuses, and the cargo and logistics industry, where there is potential to partner with global logistics firms and large retail customers. There is a further opportunity to generate revenue from other sectors such as emergency services, as eVTOL aircraft can be used for emergency patient and supplies transport, particularly in densely populated areas or military logistics transport, among other potential uses. We plan to explore the potential development of versions of Valo for such scenarios. Our strategy is to forge partnerships in key markets with partners that have existing demand and are local trusted brands with market specific knowledge. We believe that by partnering with such market players, we can extend their business models and build a market ecosystem that will allow us to expand our proposition over time. Our focus on system integration and establishment of an industrial supply chain is expected to enable rapid scaling of production of our aircraft.

Recent Developments

Business Update

On December 10, 2025, we announced the unveiling of Valo, the zero-operating emission eVTOL aircraft that we intend to design, manufacture and commercialize for deployment in the advanced air mobility market. Valo represents the successor to the Company’s VX4 prototype and incorporates a more advanced design informed by data and findings generated through our piloted test program.

On March 30, 2026, we announced the issuance of registered ordinary shares for an aggregate of $50 million, issued under our “at the market” share issuance program pursuant to the open market sale agreement, dated September 5, 2025, as amended, between us and Jefferies LLC (the “Capital Raise”). We intend to use the proceeds received under the Capital Raise to fund our research and development expenses as we continues to develop our aircraft and our expenditures in the expansion of our testing, manufacturing and certification capacities, as well as for general working capital and other general corporate purposes.

On April 16, 2026, we announced the successful completion of a two-way piloted transition flight under the direct oversight of the CAA, working in close collaboration with EASA. The successful two-way transition flight marks the completion of Phase 4 of our prototype flight tests, the final phase which tests the aircrafts’ ability to shift seamlessly between vertical lift (“helicopter mode”) and wingborne flight (“airplane mode”) and from airplane mode back again to helicopter mode, all in a single continuous flight without the need for a runway.

Cash Position

As at March 31, 2026, the Company had cash and cash equivalents totaling approximately £73 million ($96 million).

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus (including information incorporated by reference) contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) that involve substantial risks and uncertainties. All statements other than statements of historical facts contained in this prospectus, including statements regarding our future financial position, business strategy and plans and objectives of management for future operations, are forward-looking statements.

In some cases, you can identify forward-looking statements by terminology such as “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “should,” “plan,” “expect,” “predict,” “potential” or the negative of these terms or other similar expressions. Forward-looking statements include, without limitation, our expectations concerning the outlook for our business, productivity, plans and goals for future operational improvements and capital investments, operational performance, future market conditions or economic performance and developments in the capital and credit markets and expected future financial performance, as well as any information concerning our possible or assumed future results of operations.

Forward-looking statements involve a number of risks, uncertainties and assumptions, and actual results or events may differ materially from those projected or implied in those statements. Important factors that could cause such differences include, but are not limited to:

•

Our limited operating history and that we have not yet manufactured any non-prototype aircraft or sold any aircraft to customers;

•

Our business plans require a significant amount of capital and we may not be able to raise additional funds when we need or want them, or at all, to fund our operations, which could force us to curtail or even cease our planned operations and the pursuit of our growth strategy;

•

Our limited cash and cash equivalents, recurring losses from operations and dependency on raising additional capital indicate that a material uncertainty exists that may cast significant doubt (or substantial doubt as contemplated by PCAOB standards) regarding our ability to continue as a going concern;

•

If we are unable to produce, certify or launch aircraft in the volumes or timelines projected, including achieving the goals set out in Flightpath 2030;

•

Our aircraft may not perform at the level we expect and may potentially have defects;

•

Our dependence on our partners and suppliers for the components in our aircraft and for our operational needs;

•

Being an early-stage company with a history of losses, we expect to incur significant expenses and continuing losses in the foreseeable future;

•

Our markets are still in relatively early stages of growth, and such markets may not continue to grow, grow more slowly than we expect or fail to grow as large as we expect;

•

Any accidents or incidents involving electric vertical takeoff and landing (“eVTOL”) aircraft developed by us or our competitors could harm our business;

•

Our aircraft may not be certified by transportation authorities for production and operation within any projected timeline, or at all;

•

Development, testing and commercialization of a hybrid-electric vertical take-off and landing variant of the Valo aircraft is subject to significant risks, including technological, regulatory and operational challenges;

•

All of the pre-orders we have received for our aircraft are conditional and may be terminated at any time by either party and any pre-delivery payments may be fully refundable upon certain circumstances;

•

Our business has developed rapidly and expects to continue to develop significantly, and any failure to manage that growth effectively could harm our business;

TABLE OF CONTENTS

•

Our dependence on recruiting and retaining our senior management team and other highly skilled personnel;

•

We previously identified material weaknesses in our internal controls over financial reporting, which if we fail to properly remediate, could adversely affect our results of operations, investor confidence in us and the market price of our ordinary shares;

•

The anticipated use of proceeds from this offering, if any; and

•

Other risks and uncertainties described in the sections entitled “Risk Factors” in this prospectus supplement and the accompanying prospectus, and in the documents incorporated by reference into this prospectus supplement.

Many important factors, in addition to the factors described above and in other sections of this prospectus, could adversely impact our business and financial performance. Moreover, we operate in an evolving environment. New risks and uncertainties emerge from time to time, and it is not possible for our management to predict all risks and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from estimates or forward-looking statements. We qualify all of our estimates and forward-looking statements by these cautionary statements.

The estimates and forward-looking statements made in this prospectus relate only to events or information as of the date on which the statements are made in this prospectus. Except as required by law, we undertake no obligation to update or revise publicly any estimate or forward-looking statements, whether as a result of new information, future events or otherwise, after the date on which the statements are made or to reflect the occurrence of unanticipated events. We caution you against placing undue reliance on forward-looking statements, which reflect current beliefs and are based on information currently available as of the date a forward-looking statement is made. In evaluating our forward-looking statements, you should specifically consider the risks and uncertainties described in the sections entitled “Risk Factors” in this prospectus supplement and the accompanying prospectus, and in the documents incorporated by reference into this prospectus supplement.

RISK FACTORS

Investing in any securities offered pursuant to this prospectus supplement involves risks. You should carefully consider the risk factors included in this prospectus supplement and the accompanying prospectus. You should also consider the risks, uncertainties and assumptions set forth in our most recent Annual Report on Form 20-F, which is incorporated herein by reference, and in our updates, if any, to those risk factors in our reports on Form 6-K incorporated herein by reference, and all other information contained or incorporated by reference into this prospectus supplement, as updated by our subsequent filings under the Exchange Act. The risks described in these documents are not the only ones we face. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could affect our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. Please also read carefully the section titled “Cautionary Statement Regarding Forward-Looking Statements.”

The price of our securities may be volatile, and the value of our securities may decline.

We cannot predict the prices at which our securities will trade. The market price of our securities may fluctuate substantially and may be lower than the current market price. In addition, the trading price of our securities is likely to be volatile and could be subject to fluctuations in response to various factors, some of which are beyond our control. These fluctuations could cause you to lose all or part of your investment in our securities as you might be unable to sell your securities at or above the price you paid. Factors that could cause fluctuations in the trading price of our securities include the following:

•

our ability to secure additional funding to continue as a going concern;

•

actual or anticipated fluctuations in our financial condition or results of operations;

•

variance in our financial performance from expectations of securities analysts;

•

our ability to remain in compliance with continued listing standards of the NYSE;

•

changes in our projected operating and financial results;

•

delays in the certification or production of our aircraft;

•

changes in laws or regulations applicable to our platform;

•

changes in senior management or key personnel;

•

announcements by us or our competitors of significant business developments, acquisitions or new offerings;

•

changes in the pricing of our products and services;

•

significant data breaches, disruptions to or other incidents involving our platform;

•

our involvement in litigation;

•

conditions or developments affecting the eVTOL industry;

•

future sales of our ordinary shares by us or our shareholders;

•

the trading volume of securities;

•

changes in the anticipated future size and growth rate of our markets;

•

sales and short-selling of our ordinary shares;

•

publication of research reports or news stories about us, our competitors or our industry, or positive or negative recommendations or withdrawal of research coverage by securities analysts;

•

general economic and market conditions; and

•

other events or factors, including those resulting from geopolitical conflicts, war and civil unrest, incidents of terrorism, global pandemics or responses to these events.

TABLE OF CONTENTS

Broad market and industry fluctuations, as well as general economic, political, regulatory and market conditions, may also negatively impact the market price of our securities. In addition, technology stocks have historically experienced high levels of volatility. In the past, companies who have experienced volatility in the market price of their securities have been subject to securities class action litigation. We may be the target of this type of litigation in the future, which could result in substantial expenses and divert our management’s attention.

Purchasers of ordinary shares in this offering will experience immediate and substantial dilution in the book value of their investment.

The price per ordinary share being offered may be substantially higher than the as adjusted net tangible book value per ordinary share. Assuming that an aggregate of 668,896 ordinary shares are sold at a price of $2.99 per share, the last reported sale price of our ordinary shares on the NYSE on April 17, 2026, for aggregate gross proceeds of approximately $2 million, new investors in this offering will incur immediate dilution of $4.59 per share, as compared to the net tangible book value per ordinary share as of December 31, 2025. For a more detailed discussion of the foregoing see the section entitled “Dilution” below. If outstanding options or warrants are exercised, outstanding Convertible Senior Secured Notes are converted or additional equity award options are exercised under our equity incentive plans, you could experience further dilution.

We have incurred net losses (excluding fair value movements on financial liabilities at fair value through profit and loss) since inception and to date have not generated any revenue from the design, development, manufacturing, engineering and sale or distribution of aircraft. Commensurate with being in the development phase of our journey to the commercialization of our aircraft, we have invested heavily in research to support the development of our aircraft. As of December 31, 2025, we had £69 million of cash and cash equivalents on hand.

We have prepared a cash flow forecast and have considered our ability to continue as a going concern for the foreseeable future. Please see our Annual Report on Form 20-F for the year ended December 31, 2025, incorporated by reference herein, for more information. While we currently project that our existing resources will fund our operations into the middle of 2026, we require additional capital to continue to fund our ongoing operations beyond that point and to be in a position to continue to carry out our business plans prior to the commercialization of our aircraft.

The inability to obtain future funding could impact our financial condition and ability to pursue our business strategies, including being required to delay, reduce or eliminate some of our research and development programs, or materially impact our ability to certify its aircraft pursuant to its base case plan targeting certification in 2028 or continue as a going concern. Our dependency on raising additional capital indicates that a material uncertainty exists that may cast significant doubt (or substantial doubt as contemplated by PCAOB standards) about our ability to continue as a going concern and therefore we may be unable to realize our assets and discharge our liabilities in the normal course of business. Our forecast is based on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect.

While management is committed to continue to seek and raise additional funds and may seek to issue further equity in doing so, there can be no assurance that we will be able to obtain additional funding on acceptable terms, if at all. To the extent that we raise additional capital through future equity offerings, the ownership interest of ordinary shareholders will be diluted, which dilution may be significant. Any equity securities issued may also provide for rights, preferences or privileges senior to those of holders of ordinary shares. Additionally, if we raise funds by issuing debt securities, these debt securities may have rights, preferences, and privileges senior to those of our shareholders. The terms of debt securities or borrowings may impose significant restrictions on our operations. We cannot guarantee that we will be able to obtain any or sufficient additional funding or that such funding, if available, will be obtainable on terms satisfactory to us. We may also seek to defer certain operating expenses unless and until additional capital is received. In

the event that we are unable to obtain any or sufficient additional funding or defer sufficient operating expenses, there can be no assurance that we will be able to continue as a going concern, and we may be forced to delay, reduce or discontinue certain activities, including planned research and development activities, hiring plans, flight tests and manufacturing activities or commercialization efforts.

Significant doubt (or substantial doubt as contemplated by PCAOB standards) about our ability to continue as a going concern may materially and adversely affect the price per share of our ordinary shares, and it may be more difficult for us to obtain financing. If potential collaborators decline to do business with us or potential investors decline to participate in any future financings due to such concerns, our ability to increase our cash position may be limited. The perception that we may not be able to continue as a going concern may cause others to choose not to deal with us due to concerns about our ability to meet our contractual obligations.

We have prepared our consolidated financial statements assuming that we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. Our consolidated financial statements included in our Annual Report on Form 20-F for the year ended December 31, 2025, incorporated by reference into this prospectus supplement, do not include any adjustments to reflect the possible inability to continue as a going concern. If we are unable to continue as a going concern, you could lose all or part of your investment.

Please refer to note 2 to our consolidated financial statements for the year ended December 31, 2025 included in our Annual Report on Form 20-F for the year ended December 31, 2025 incorporated by reference into this prospectus supplement for more information.

We may be characterized as a PFIC for U.S. federal income tax purposes, which may cause adverse U.S. federal income tax consequences to U.S. investors.

A non-U.S. corporation generally will be treated as a PFIC for U.S. federal income tax purposes, in any taxable year if either (1) at least 75% of its gross income for such year is passive income or (2) at least 50% of the value of its assets (generally based on an average of the quarterly values of the assets) during such year is attributable to assets that produce or are held for the production of passive income. If we are a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder (as defined under “Material U.S. Federal Income Tax Consequences to U.S. Holders”) of ordinary shares, such U.S. Holder may be subject to adverse U.S. federal income tax consequences and may be subject to additional reporting requirements. We remain an early-stage company and do not expect to realize revenue until our aircraft are manufactured and delivered to our customers. Until we generate revenue, our PFIC status would largely depend on whether we earn non-passive income, such as government grants and research and development tax credits, and whether the amount of such non-passive income exceeds 25% of our gross income for the relevant taxable year. While not clear, taking into account our income, assets and market capitalization, we expect that we will not be a PFIC for our current taxable year. However, whether we are treated as a PFIC is a factual determination that must be made annually after the close of each taxable year. Accordingly, there can be no assurances that we will not be classified as a PFIC for the current taxable year or any future taxable year.

Even after we start generating revenue, our PFIC status would depend on, among other things, the composition of the income, assets and operations of us and our subsidiaries, and there can be no assurances that we will not be treated as a PFIC in any future taxable year. In addition, our PFIC status may be impacted by our market capitalization, which may fluctuate significantly. Moreover, the application of the PFIC rules is subject to uncertainty in several respects, and we cannot assure you that the IRS will not take a contrary position or that a court will not sustain such a challenge by the IRS. Furthermore, if a U.S. Holder holds our ordinary shares and we are a PFIC during such U.S. Holder’s holding period, unless the U.S. Holder makes certain elections, we will continue to be treated as a PFIC with respect to such U.S. Holder, even if we cease to be a PFIC in future taxable years.

For a further discussion, see “Material U.S. Federal Income Tax Consequences to U.S. Holders — Passive Foreign Investment Company.” U.S. Holders of our ordinary shares are strongly encouraged to consult their own advisors regarding the potential application of these rules to us and the ownership of our ordinary shares.

DIVIDEND POLICY

We have never declared or paid any cash dividend, and do not anticipate paying any dividends in the foreseeable future. We currently intend to retain future earnings, if any, to finance operations and expand our business. Our board of directors has sole discretion whether to pay dividends. If our board of directors decides to pay dividends, the form, frequency and amount will depend upon our future operations and earnings, capital requirements and surplus, general financial condition, contractual restrictions and other factors that our directors may deem relevant.

TABLE OF CONTENTS

DILUTION

If you invest in our ordinary shares in this offering, your ownership interest will be immediately diluted to the extent of the difference between the assumed public offering price per ordinary share in this offering and the net tangible book value per ordinary share after this offering.

Our net tangible book value as of December 31, 2025 was $(163.356) million, or $(1.61) per share, calculated based on the GBP/USD exchange rate of £1 to $1.3451 as of December 31, 2025. Net tangible book value per share is determined by dividing our total tangible assets (including right of use assets), less total liabilities, by the number of ordinary shares outstanding as of December 31, 2025. Dilution in net tangible book value per share represents the difference between the assumed amount per ordinary share paid by purchasers in this offering and the as adjusted net tangible book value per ordinary share immediately after giving effect to this offering.

Our as adjusted net tangible book value as of December 31, 2025 would be $(163.356) million, or $(1.60) per ordinary share (on an as-converted basis). As adjusted net tangible book value per share reflects the issuance by us of 668,896 Commitment Shares, at an assumed price of $2.99 per share (the last reported sale price of our ordinary shares on the NYSE on April 17, 2026). This represents an immediate increase in as adjusted net tangible book value of $0.01 per share to existing shareholders and immediate dilution of $4.59 per share to new investors purchasing shares in the offering, as illustrated in the following table:

Assumed public offering price per ordinary share			$	2.99
Net tangible book value per ordinary share as of December 31, 2025(1)	$	(1.61)
Increase in net tangible book value per ordinary share attributable to this offering	$	0.01
As adjusted net tangible book value per ordinary share after giving effect to this offering			$	(1.60)
Dilution in net tangible book value per ordinary share to new investors participating in this offering			$	4.59

(1)

Calculated based on 101,602,621 ordinary shares outstanding as of December 31, 2025.

Upon the vesting and settlement of outstanding RSUs, and to the extent that outstanding options or warrants are exercised or outstanding Convertible Senior Secured Notes are converted, new investors will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders.

The foregoing table and calculations exclude the following shares as of December 31, 2025 (see “The Offering” for additional share information as of March 31, 2026):

•

8,597,991 ordinary shares issuable upon the exercise of share options outstanding (out of which 2,404,020 share options were fully vested) as of December 31, 2025, having a weighted-average exercise price of $2.02 (or £1.50, calculated based on the GBP/USD exchange rate of £1 to $1.3451 as of December 31, 2025) per share;

•

10,244,352 ordinary shares reserved for issuance pursuant to future equity awards under our Amended and Restated 2021 Incentive Award Plan and the EMI Option Agreements as of December 31, 2025, as well as any future increases in the number of ordinary shares reserved for future issuance under this plan;

•

41,796,270 ordinary shares issuable upon the conversion of the Convertible Senior Secured Notes outstanding as of December 31, 2025; and

•

22,338,993 ordinary shares issuable upon the exercise of warrants outstanding as of December 31, 2025.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax considerations for U.S. Holders (as defined below) of the ownership and disposition of our ordinary shares pursuant to this offering. In addition, as a preliminary matter, the issuance of our ordinary shares to the Investor in consideration of the Investor’s commitment to enter into the SEPA will be treated as a fee for such commitment and generally will be subject to U.S. federal income taxation in the same manner as if the fee was instead made in cash to the Investor. The Investor considering the receipt of our ordinary shares in consideration of the Investor’s commitment to enter into the SEPA should consult its own tax advisors regarding the tax consequences to it of the receipt of our ordinary shares. This discussion applies only to our ordinary shares that are held as “capital assets” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”) (generally, property held for investment).

The following does not purport to be a complete analysis of all potential tax considerations arising in connection with the ownership and disposition of our ordinary shares. The effects and considerations of other U.S. federal tax laws, such as estate and gift tax laws, alternative minimum or Medicare contribution tax consequences and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Code, Treasury regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the IRS, in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect the tax consequences discussed below. We have neither sought nor will seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS will not take or a court will not sustain a contrary position to that discussed below regarding the tax consequences discussed below.

This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

•

banks, insurance companies, and certain other financial institutions;

•

regulated investment companies and real estate investment trusts;

•

brokers, dealers or traders in securities;

•

traders in securities that elect to mark to market;

•

tax-exempt organizations or governmental organizations;

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons holding our ordinary shares as part of a hedge, straddle, constructive sale, or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to our ordinary shares being taken into account in an applicable financial statement;

•

persons that actually or constructively own 5% or more (by vote or value) of our shares;

•

“controlled foreign corporations,” “foreign controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

•

S corporations, entities or arrangements treated as partnerships or other flowthrough entities for U.S. federal income tax purposes (and investors therein);

•

persons having a functional currency other than the U.S. dollar;

•

persons who hold or received our ordinary shares, as the case may be, pursuant to the exercise of any employee share option or otherwise as compensation; and

•

tax-qualified retirement plans.

S-16

TABLE OF CONTENTS

For purposes of this discussion, a “U.S. Holder” is any beneficial owner of our ordinary shares that is for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation (or other entity taxable as a corporation) created or organized under the laws of the United States, any state thereof, or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a “United States person” (within the meaning of Section 7701(a)(30) of the Code) for U.S. federal income tax purposes.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our ordinary shares, the tax treatment of an owner of such partnership will depend on the status of the partners, the activities of the partnership and certain determinations made at the partner level. Accordingly, entities or arrangements treated as partnerships for U.S. federal income tax purposes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THE U.S. FEDERAL INCOME TAX CONSEQUENCE OF OWNING OUR ORDINARY SHARES TO ANY PARTICULAR HOLDER WILL DEPEND ON THE HOLDER’S PARTICULAR TAX CIRCUMSTANCES. YOU ARE URGED TO CONSULT YOUR TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE, LOCAL, AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES TO YOU, IN LIGHT OF YOUR PARTICULAR INVESTMENT OR TAX CIRCUMSTANCES, OF ACQUIRING, HOLDING, AND DISPOSING OF OUR ORDINARY SHARES.

Distributions on Ordinary Shares

Subject to the PFIC rules discussed below, the gross amount of distributions made by us (if any) with respect to the ordinary shares generally will be includable in a U.S. Holder’s gross income as foreign-source dividend income in the year actually or constructively received by such U.S. Holder, but only to the extent that such distributions are paid out of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. Distributions to a U.S. Holder in excess of current and accumulated earnings and profits will be treated as a non-taxable return of capital to the extent of the U.S. Holder’s basis in the ordinary shares and thereafter as capital gain. In the event we make distributions to U.S. Holders of ordinary shares, we may or may not calculate our earnings and profits under U.S. federal income tax principles. We do not currently intend to calculate our earnings and profits under U.S. federal income tax principles. U.S. Holders should therefore assume that all cash distributions will be reported as ordinary dividend income, even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain. The amount of any distribution of property other than cash will be the fair market value of that property on the date of distribution. U.S. Holders should consult their own tax advisors to determine whether and to what extent they will be entitled to foreign tax credits in respect of any dividend income received.

With respect to non-corporate U.S. Holders (including individuals, estates, and trusts), dividends received with respect to our ordinary shares may be considered “qualified dividend income” subject to lower capital gains rates, provided that (1) the ordinary shares are readily tradable on an established securities market in the United States or we are eligible for the benefits of the income tax treaty between the United States and the United Kingdom, (2) we are not a PFIC (as discussed below) for either our taxable year in which the dividend was paid or the preceding taxable year and (3) certain holding period requirements are met. In this regard, the ordinary shares will generally be considered to be readily tradable on an established securities market in the United States if they are listed on the NYSE, as we intend the ordinary shares will continue to be. U.S. Holders should consult their own tax advisors regarding the availability of the lower rate for the dividends paid with respect to the ordinary shares.

Subject to certain exceptions, dividends paid by us with respect to the ordinary shares will generally constitute foreign-source “passive category income” and will not be eligible for the dividends-received deduction generally allowed to corporate U.S. Holders in respect of dividends received from U.S. corporations.

TABLE OF CONTENTS

Sale or Other Taxable Disposition of Ordinary Shares

Subject to the PFIC rules discussed below, upon a sale or other taxable disposition of the ordinary shares, a U.S. Holder generally will recognize a capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in such ordinary shares. Any such gain or loss generally will be U.S.-source gain or loss and will be treated as long-term capital gain or loss if the U.S. Holder’s holding period in the ordinary shares exceeds one year. Non-corporate U.S. Holders (including individuals) generally will be subject to U.S. federal income tax on long-term capital gain at preferential rates. The deductibility of capital losses is subject to significant limitations.

Any such gain or loss recognized generally will be treated as U.S. source gain or loss. U.S. Holders are urged to consult their own tax advisor regarding the ability to claim a foreign tax credit and the application of the income tax treaty between the United States and the United Kingdom to such U.S. Holder’s particular circumstances.

Passive Foreign Investment Company

We will be classified as a PFIC within the meaning of Section 1297 of the Code, for any taxable year if either: (1) at least 75% of the gross income of the Company is “passive income” for purposes of the PFIC rules, the so-called PFIC income test, or (2) at least 50% of the value of our assets (determined on the basis of a quarterly average) produce or are held for the production of passive income, the so-called PFIC asset test. For this purpose, we will be treated as owning the proportionate share of the assets, and earning the proportionate share of the income, of any other corporation in which we own, directly or indirectly, 25% or more measured by value of the stock. We are an early stage company and do not expect to realize revenue until our manufacturing operations are in production. Until we generate revenue, our PFIC status would largely depend on whether we earn non-passive income, such as government grants and research and development tax credits, and whether the amount of such non-passive income exceeds 25% of our gross income for the relevant taxable year. While not clear, taking into account our income, assets and market capitalization, we believe we were not a PFIC for the taxable year that ended on December 31, 2025 and we expect that we will not be a PFIC for our current taxable year. However, whether we are treated as a PFIC is a factual determination that must be made annually after the close of each taxable year. Accordingly, there can be no assurances that we will not be classified as a PFIC for the current taxable year. Even after we start generating revenue, our PFIC status would depend on, among other things, the composition of the income, assets and operations of us and our subsidiaries and there can be no assurances that we will not be treated as a PFIC in any future taxable year. In addition, fluctuations in our market capitalization could affect the analysis under the PFIC asset test. Moreover, the application of the PFIC rules is subject to uncertainty in several respects, and we cannot assure you that the IRS will not take a contrary position or that a court will not sustain such a challenge by the IRS.

If we are considered a PFIC for any taxable year that a U.S. Holder holds ordinary shares, we would continue to be treated as a PFIC with respect to such U.S. Holder’s investment unless (i) we ceased to be a PFIC and (ii) the U.S. Holder made a “deemed sale” election under the PFIC rules. If such election is made, a U.S. Holder will be deemed to have sold its ordinary shares at their fair market value on the last day of the last taxable year in which we are classified as a PFIC, and any gain from such deemed sale would be subject to the consequences described below. After the deemed sale election, the ordinary shares with respect to which the deemed sale election was made will not be treated as shares in a PFIC unless we subsequently become a PFIC.

For each taxable year that we are treated as a PFIC with respect to a U.S. Holder’s ordinary shares, the U.S. Holder will be subject to special tax rules with respect to any “excess distribution” (as defined below) received and any gain realized from a sale or disposition (including a pledge) of its ordinary shares (collectively the “Excess Distribution Rules”), unless the U.S. Holder makes a valid QEF election or mark-to-market election as discussed below. Distributions received by a U.S. Holder in a taxable year that are greater than 125% of the average annual distributions received during the shorter of the three preceding taxable years or the U.S. Holder’s holding period for the ordinary shares will be treated as excess distributions. Under the Excess Distribution Rules:

S-18

TABLE OF CONTENTS

•

the excess distribution or gain (including gain on a sale or disposition of ordinary shares) will be allocated ratably over the U.S. Holder’s holding period for the ordinary shares;

•

the amount allocated to the current taxable year, and any taxable years in the U.S. Holder’s holding period prior to the first taxable year in which we are a PFIC, will be treated as ordinary income; and

•

the amount allocated to each other taxable year will be subject to the highest tax rate in effect for individuals or corporations, as applicable, for each such year and the interest charge generally applicable to underpayments of tax will be imposed on the resulting tax attributable to each such year.

Under the Excess Distribution Rules, the tax liability for amounts allocated to taxable years prior to the year of disposition or excess distribution cannot be offset by any net operating losses, and gains (but not losses) realized on the sale of the ordinary shares cannot be treated as capital gains, even though the U.S. Holder holds the ordinary shares as capital assets.

Once we are a PFIC, U.S. Holders may also be subject to the Excess Distribution Rules with respect to subsidiaries and other entities which we may hold, directly or indirectly, that are PFICs (collectively, “Lower-Tier PFICs”). There can be no assurance that we do not own, or will not in the future acquire, an interest in a subsidiary or other entity that is or would be treated as a Lower-Tier PFIC. U.S. Holders should consult their own tax advisors regarding the application of the PFIC rules to any of our Lower-Tier PFICs.

If we are a PFIC, a U.S. Holder of ordinary shares may avoid taxation under the Excess Distribution Rules described above by making a “qualified electing fund” (“QEF”) election. However, a U.S. Holder may make a QEF election with respect to its ordinary shares only if we provide U.S. Holders on an annual basis with certain financial information specified under applicable U.S. Treasury regulations. Because we do not intend to provide such information, however, the QEF Election will not be available to U.S. Holders with respect to our ordinary shares.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) may make a mark-to-market election for its ordinary shares to elect out of the Excess Distribution Rules discussed above if we are treated as a PFIC. If a U.S. Holder makes a mark-to-market election with respect to its ordinary shares, such U.S. Holder will include in income for each year that we are treated as a PFIC with respect to such ordinary shares an amount equal to the excess, if any, of the fair market value of the ordinary shares as of the close of the U.S. Holder’s taxable year over the adjusted basis in the ordinary shares. A U.S. Holder will be allowed a deduction for the excess, if any, of the adjusted basis of the ordinary shares over their fair market value as of the close of the taxable year. However, deductions will be allowed only to the extent of any net mark-to-market gains on the ordinary shares included in the U.S. Holder’s income for prior taxable years. Amounts included in income under a mark-to-market election, as well as gain on the actual sale or other disposition of the ordinary shares, will be treated as ordinary income. Ordinary loss treatment will also apply to the deductible portion of any mark-to-market loss on the ordinary shares, as well as to any loss realized on the actual sale or disposition of the ordinary shares, to the extent the amount of such loss does not exceed the net mark-to-market gains for such ordinary shares previously included in income. A U.S. Holder’s basis in the ordinary shares will be adjusted to reflect any mark-to-market income or loss. If a U.S. Holder makes a mark-to-market election, any distributions we make would generally be subject to the rules discussed above under “— Distributions on Ordinary Shares,” except the lower rates applicable to qualified dividend income would not apply.

The mark-to-market election is available only for “marketable stock,” which is stock that is regularly traded on a qualified exchange or other market, as defined in applicable U.S. Treasury regulations. The ordinary shares, which are listed on NYSE, are expected to qualify as marketable stock for purposes of the PFIC rules, but there can be no assurance that ordinary shares will be “regularly traded” for purposes of these rules. Because a mark-to-market election is generally not available for equity interests in any Lower-Tier PFICs, a U.S. Holder will continue to be subject to the Excess Distribution Rules with respect to its indirect interest in any Lower-Tier PFICs as described above, even if a mark-to-market election is made for the ordinary shares.

If a U.S. Holder does not make a mark-to-market election (or a QEF election) effective from the first taxable year of a U.S. Holder’s holding period for the ordinary shares in which we are a PFIC, then the U.S.

S-19

TABLE OF CONTENTS

Holder generally will remain subject to the Excess Distribution Rules. A U.S. Holder that first makes a mark-to-market election with respect to the ordinary shares in a later year will continue to be subject to the Excess Distribution Rules during the taxable year for which the mark-to-market election becomes effective, including with respect to any mark-to-market gain recognized at the end of that year. In subsequent years for which a valid mark-to-mark election remains in effect, the Excess Distribution Rules generally will not apply. A U.S. Holder that is eligible to make a mark-to-market with respect to its ordinary shares may do so by providing the appropriate information on IRS Form 8621 and timely filing that form with the U.S. Holder’s tax return for the year in which the election becomes effective. U.S. Holders should consult their own tax advisors as to the availability and desirability of a mark-to-market election, as well as the impact of such election on interests in any Lower-Tier PFICs.

A U.S. Holder of a PFIC may be required to file an IRS Form 8621 on an annual basis. U.S. Holders should consult their own tax advisors regarding any reporting requirements that may apply to them if we are a PFIC.

U.S. Holders are strongly encouraged to consult their tax advisors regarding the application of the PFIC rules to their particular circumstances.

Information Reporting and Backup Withholding

Information reporting requirements may apply to distributions received by U.S. Holders of ordinary shares, and the proceeds received on sale or other taxable disposition of ordinary shares effected within the United States (and, in certain cases, outside the United States), in each case other than U.S. Holders that are exempt recipients (such as corporations). Backup withholding may apply to such amounts if the U.S. Holder fails to provide an accurate taxpayer identification number (generally on an IRS Form W-9 provided to the paying agent of the U.S. Holder’s broker) or is otherwise subject to backup withholding. Any distributions with respect to ordinary shares and proceeds from the sale, exchange, redemption or other disposition of ordinary shares may be subject to information reporting to the IRS and possible U.S. backup withholding. U.S. Holders should consult their own tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding generally may be credited against the taxpayer’s U.S. federal income tax liability, and a taxpayer may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for a refund with the IRS and furnishing any required information.

OUR COMPANY

Company Overview

Our vision is to transform how the world moves. We are a global aerospace and technology company that is pioneering electric aviation, focused on designing, manufacturing and selling a zero operating emission eVTOL aircraft for use in the advanced air mobility market, using the most cutting-edge technology from the aerospace, automotive and energy industries.

Founded in 2016, we come from a deep aerospace and automotive mindset and have designed, built and flown two sub-scale prototype eVTOL aircraft in 2018 and 2019. We are currently developing, and are progressing towards the certification of, our flagship eVTOL, the VX4 in 2028. Our first full-scale VX4 prototype commenced flight testing in July 2023 and successfully progressed through its thrustborne flight-test program. Our second, more advanced, full-scale VX4 prototype commenced flight tests in July 2024, achieving the milestone of piloted thrustborne flight manoeuvres in January 2025. The assembly of our third full-scale VX4 prototype, identical to the second, is underway. Both our second, and soon to be third, prototypes include much of our strategic partners’ technology that we plan to incorporate into our final certification aircraft.

In March 2023, the United Kingdom’s Civil Aviation Authority (“CAA”) issued an eVTOL Design Organisation Approval (“DOA”) to our wholly-owned subsidiary, Vertical Aerospace Group Limited (“VAGL”). UK and European aerospace companies cannot hold a type certificate without being granted a DOA. The DOA authorises VAGL to conduct design activities and issue design approvals within the DOA’s scope of approval. In July 2024, the CAA expanded the scope of our DOA and agreed its certification cooperation with the European Union Aviation Safety Agency (“EASA”) on certification activities for the VX4.

We are targeting the VX4 to be capable of transporting a pilot and up to four passengers at entry into service, traveling distances of up to 100 miles, and achieving cruise speeds of 150 miles per hour, while producing minimal noise and zero operating emissions.

TABLE OF CONTENTS

DESCRIPTION OF SHARE CAPITAL AND ARTICLES OF ASSOCIATION

The following summary of the material terms of our share capital is not intended to be a complete summary of the rights and preferences of such securities, and should be read together with the Company’s fourth amended and restated memorandum and articles of association dated effective on December 23, 2024 (the “Articles”). We urge to you read the Articles in its entirety for a complete description of the rights and preferences of our share capital.

General

We are a Cayman Islands exempted company with limited liability (company number 376116). Our affairs are governed by our Articles as amended and restated from time to time and the Companies Act (As Revised) of the Cayman Islands (the “Companies Act”).

Our objects are unrestricted, and Section 3 of our Articles provides that we shall have full power and authority to carry out any object not prohibited by the laws of the Cayman Islands.

Our register of members is maintained by Continental Stock Transfer & Trust Company.

Ordinary Shares

General

The authorized share capital of the Company is $210,000 divided into 200,000,000 ordinary shares, par value $0.001 per share, and 10,000,000 preferred shares, par value $0.001 per share. As of March 31, 2025, there were 84,602,721 ordinary shares issued and outstanding. All of our issued and outstanding ordinary shares are fully paid and non-assessable. Certificates representing our issued and outstanding ordinary shares are generally not issued and legal title to our issued shares is recorded in registered form in the register of members. Other than as described below under the heading “Shareholder Participation Rights,” holders of ordinary shares do not have any conversion, preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to the ordinary shares.

We currently have only one class of issued ordinary shares, which have identical rights in all respects and rank equally with one another. There is no cumulative voting with respect to the election of directors at a general meeting, with the result that the holders of more than 50% of the shares voted for the election of directors can elect the directors, subject to the director nomination rights held by Mudrick Capital and Stephen Fitzpatrick’s right to serve as a General Director, as described below under the heading “— Directors.”

Our Board may provide for other classes of shares, including classes of preferred shares, out of our authorized but unissued share capital, which could be utilized for a variety of corporate purposes, including future offerings to raise capital for corporate purposes or for use in employee benefit plans. Such additional classes of shares shall have such rights, restrictions, preferences, privileges and payment obligations as determined by our Board. If we issue any preferred shares, the rights, preferences and privileges of holders of our ordinary shares will be subject to, and may be adversely affected by, the rights of the holders of such preferred shares. See “— Variations of Rights of Shares.”

As of March 31, 2025, there were 84,602,721 ordinary shares issued and outstanding. In addition, as of March 31, 2025, we had 22,188,993 ordinary shares issuable upon the exercise of outstanding warrants, and 37,198,531 ordinary shares issuable upon conversion of the Convertible Senior Secured Notes.

Dividends

The holders of our ordinary shares are entitled to such dividends as may be declared by our Board subject to the Companies Act and our Articles. Dividends and other distributions on issued and outstanding ordinary shares may be paid out of the funds of the Company lawfully available for such purpose, subject to any preference of any outstanding preferred shares. Dividends and other distributions will be distributed among the holders of our ordinary shares on a pro rata basis. Subject to the foregoing, the payment of cash dividends in the future, if any, will be at the discretion of our Board and will depend upon such factors

TABLE OF CONTENTS

as earnings levels, capital requirements, contractual restrictions, our overall financial condition, available distributable reserves and any other factors deemed relevant by our Board.

Voting Rights

Holders of ordinary shares are entitled to one vote for each share held of record on all matters to be voted on by shareholders. A quorum required for a meeting of shareholders consists of members holding at least a simple majority of all voting share capital in issue at any such general meeting of the Company. Voting at any meeting of shareholders is by poll and not on a show of hands.

A special resolution will be required for important matters such as a merger or consolidation of the Company, change of name or making changes to our Articles or the voluntary winding up of the Company.

The adoption of any ordinary resolution by our shareholders requires the affirmative vote of a simple majority of the votes permitted to be cast by persons present (in person or by proxy) and voting at a general meeting at which a quorum is present, while a special resolution requires the affirmative vote of no less than two-thirds of the votes permitted to be cast by persons present (in person or by proxy) and voting at any such meeting, or, in each case, a unanimous resolution in writing.

Shareholder Meetings

Our Articles provide that notice of any general meeting shall be provided to each shareholder entitled to vote at such meeting not less than seven calendar days but not more than sixty calendar days before the date of the meeting. The notice shall specify the place, if any, date and time of the meeting, the means of remote communication, if any, by which shareholders and proxy holders may be deemed to be present in person and vote at such meeting, and, in the case of an extraordinary general meeting, the purpose or purposes for which the meeting is called. No business shall be transacted at any general meeting unless a quorum of shareholders is present at the time when the meeting proceeds to business. A quorum required for a meeting of shareholders consists of members holding at least a simple majority of all voting share capital in issue at any such general meeting of the Company.

Under our Articles, all general meetings of the Company other than annual general meetings are called extraordinary general meetings. No business may be transacted at any general meeting other than business properly brought before the meeting.

Annual General Meetings

Our Articles provide that the Company shall hold an annual general meeting in each fiscal year of the Company, to be held at such time and place as our directors approve. To be properly brought before an annual general meeting, business must be (i) specified in a notice of meeting given by or at the direction of the Board, (ii) otherwise brought before the meeting by the Board or the chairman of the Board, or (iii) notified to the Company in writing not later than the seventh day after the delivery of notice of such meeting by shareholders holding greater than an aggregate of 10.0% of the issued and outstanding ordinary shares.

Extraordinary General Meetings

Our Articles provide that extraordinary general meetings for any purpose or purposes may be called at any time (i) by a resolution adopted by the majority of our directors or (ii) by the Board upon a valid request by shareholders holding an aggregate of 10.0% of the issued and outstanding ordinary shares. To be properly brought before an extraordinary general meeting, business must be specified in a notice of meeting given by or at the direction of the person calling the meeting, which may include any such business as the requesting shareholders may propose, subject to applicable law.

The Board can, in good faith, refuse the calling of an extraordinary general meeting at the request of shareholders holding greater than an aggregate of 10.0% of the ordinary shares issued and outstanding, but only if the resolution proposed to be dealt with at the extraordinary general meeting cannot be properly moved because it would be contrary to applicable law. If the Board does not convene an extraordinary general meeting within twenty-one days from the date on which a valid request is received, other than in the limited circumstances in which the Board would have a right to refuse the calling of an extraordinary

TABLE OF CONTENTS

general meeting, the requesting shareholders may convene an extraordinary general meeting, which shall be convened in the same manner as nearly as possible as that in which extraordinary general meetings are convened by the Board.

Variations of Rights of Shares

Under the Articles, if our share capital is divided into more than one class of shares, the rights attached to any such class may, whether or not the Company is being wound up, be varied without the consent of the holders of the issued shares of that class where such variation is considered by our directors not to have a material adverse effect upon such rights; otherwise, any such variation shall be made only with the consent in writing of the holders of not less than two thirds of the issued shares of that class or with the approval of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the shares of that class.

Options

Our board of directors is empowered to grant options with or without preferred, deferred, or other rights or restrictions. We currently have in place two employee incentive plans under which options in our ordinary shares can be granted to eligible employees.

Transfer of Ordinary Shares

Any of our shareholders may transfer all or any of their ordinary shares by an instrument of transfer in the usual or common form or any other form prescribed by the stock exchange, the SEC and/or any other competent regulatory authority or otherwise under applicable law, or approved by our Board, subject to the applicable restrictions of our Articles, such as the determination by the directors that a proposed transfer is not eligible.

Ownership Threshold

There are no provisions under Cayman Islands law applicable to us, or under the Articles, that require us to disclose shareholder ownership above any particular ownership threshold.

Rights of Non-Resident or Foreign Shareholders

There are no limitations imposed by the Articles on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in the Articles governing the ownership threshold above which shareholder ownership must be disclosed.

Anti-Takeover Provisions in the Articles

Some provisions of the Articles may discourage, delay or prevent a change of control of Vertical or our management that shareholders may consider favorable, including director nomination rights granted to Mudrick Capital for a number of directors proportionate in number to its share ownership percentage so long as Mudrick Capital beneficially owns greater than 10.0% of our issued and outstanding ordinary shares, and a provision that authorizes our Board to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders.

Liquidation

On a winding-up or other return of capital, subject to any special rights attaching to any other class of shares, holders of ordinary shares will be entitled to participate in any surplus assets in proportion to their shareholdings.

Calls on Shares and Forfeiture of Shares

Our Board may from time to time make calls upon shareholders for any amounts unpaid on their shares in a notice served to such shareholders at least 14 days prior to the specified time of payment. The shares that have been called upon and remain unpaid are subject to forfeiture.

Shareholder Participation Rights

Pursuant to a Shareholder Letter Agreement, dated as of December 23, 2024, by and among the Company, Mudrick Capital, Stephen Fitzpatrick and Imagination Aero Investments Limited (“Imagination Aero”), a wholly owned entity of Mr. Fitzpatrick, so long as (i) Mudrick Capital directly or indirectly beneficially owns at least 20% of our issued and outstanding ordinary shares or (ii) Mr. Fitzpatrick and Imagination Aero, together with any other fund, entity or account that is affiliated with Mr. Fitzpatrick (the “SF Parties”), directly or indirectly beneficially owns at least 3% of our issued and outstanding ordinary shares, Mudrick Capital and/or the SF Parties may elect to participate in our offering of newly issued ordinary shares and any other securities (including any equity securities or debt securities that are convertible into ordinary shares or the other equity securities of Vertical or our subsidiaries) (the “New Securities”) at a price and on the terms specified in the relevant offer notice, up to such number of New Securities proportionate to Mudrick Capital and/or the SF Parties’ beneficial ownership of our issued and outstanding ordinary shares relative to the number of New Securities to be offered by us.

Directors

Our management is vested in our Board. Our Articles provide that questions arising at any meeting of directors shall be decided by the votes of a majority of the directors presented at a duly held meeting at which a quorum is present, or by unanimous written resolution of the Board. The quorum necessary for any Board meeting shall consist of at least a majority of the members of our Board.

Our Articles provide that the Board shall consist of up to seven directors (but not less than one director), unless increased or decreased from time to time by the directors or the Company in a general meeting, and the Board shall consist of a majority of independent directors.

Pursuant to our Articles, so long as Mudrick Capital beneficially owns at least 10.0% of our issued and outstanding ordinary shares, Mudrick Capital shall be entitled to nominate for election a number of individuals to serve as directors on the Board proportionate in number (rounded to the nearest whole number), on the basis of a Board consisting of seven directors, to Mudrick Capital’s percentage of beneficial ownership of the our issued and outstanding ordinary shares (each, upon the effectiveness of their appointment, an “Appointed Director”). Such nomination rights shall terminate on the first date on which Mudrick Capital beneficially owns less than 10.0% of our issued and outstanding ordinary shares on a fully diluted basis (assuming the exercise or exchange of all Vertical warrants, options and other similar instruments that are able to be exercised or exchanged as at the relevant date, and the full conversion of the outstanding Convertible Senior Secured Notes issued under the Indenture that are held by Mudrick Capital as at the relevant date), and the maximum number of Appointed Directors shall be capped as six so long as the SF Entitlement (as defined below) is applicable. Any casual vacancy on the Board in respect of an Appointed Director position shall be subject to Mudrick Capital’s nomination rights.

Our Articles provide that the nominating and corporate governance committee of the Board (the “Nominating and Governance Committee”) shall review each candidate nominated by Mudrick Capital to be an independent director for fitness and, if deemed fit for service, the Nominating and Governance Committee will recommend the individuals for election by a majority vote of the Board. The Nominating and Governance Committee shall recommend for election by a majority vote of the Board each candidate deemed fit for service by Mudrick and nominated by Mudrick Capital to be a non-independent Appointed Director.

Director positions other than for an Appointed Director (each such director, a “General Director”) may be filled by the affirmative vote of a simple majority of the remaining directors present and voting at a Board meeting, or by ordinary resolution (or, in the event that there is more than one individual proposed in respect of a single General Director position, by a plurality of votes) at a general meeting of the Company’s shareholders. So long as the SF Parties beneficially own at least 3% of our issued and outstanding ordinary shares, Mr. Fitzpatrick shall be entitled to serve as a General Director on the Board (the “SF Entitlement”).

A director may be removed from office by an ordinary resolution of the shareholders with cause, and any director other than Mr. Fitzpatrick may be removed from office by an ordinary resolution of the

TABLE OF CONTENTS

shareholders without cause, in each case at any time before the expiration of their term. Other than in respect of an independent Appointed Director, Mudrick Capital may remove any Appointed Director by delivering notice to the Company.

Each director shall hold office until the expiration of his or her term, until his or her successor shall have been duly elected and qualified or until his or her earlier death, resignation or removal.

There is no cumulative voting with respect to the appointment of directors.

Under our Articles, directors who are in any way, whether directly or indirectly, interested in a contract or proposed contract with our company must declare the nature of their interest at a meeting of the board of directors. Following such declaration, a director may vote in respect of any contract or proposed contract notwithstanding their interest; provided that, in exercising any such vote, such director complies with their fiduciary duties and any other applicable duties.

Our directors are entitled to such remuneration as the directors may from time to time determine.

Indemnity of Directors and Officers

Our Articles provide that our Board and officers shall be indemnified from and against all liability which they incur in execution of their duty in their respective offices to the fullest extent permitted under the laws of the Cayman Islands.

Differences in Company Law

Cayman Islands companies are governed by the Companies Act. The Companies Act is modeled on English Law but does not follow recent English Law statutory enactments, and differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the material differences between the provisions of the Companies Act applicable to us and the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and Similar Arrangements

In certain circumstances, the Companies Act allows for mergers or consolidations between two Cayman Islands companies, or between a Cayman Islands exempted company and a company incorporated in another jurisdiction (provided that it is permitted or not prohibited by the constitutional documents of the company incorporated in another jurisdiction and facilitated by the laws of that other jurisdiction).

Where the merger or consolidation is between two Cayman Islands companies, the directors of each company must approve a written plan of merger or consolidation containing certain prescribed information. That plan of merger or consolidation must then be authorized by (a) a special resolution (usually the affirmative vote of the holders of at least a two-thirds (2/3) majority of the issued ordinary shares of the company that are present in person or represented by proxy and entitled to vote thereon and who vote at the general meeting) of the shareholders of each company; and (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. Unless required by its articles of association, no shareholder resolution is required for a merger between a parent company (i.e., a company that owns at least 90% of the issued shares of each class in a subsidiary company) and its subsidiary company if a copy of the plan of merger or consolidation is given to every member of the subsidiary company unless that member agrees otherwise.

The consent of each holder of a fixed or floating security interest of a constituent company must be obtained, unless the Cayman Islands court waives such requirement or makes such order as the Cayman Islands court otherwise considers reasonable. If the Registrar of Companies of the Cayman Islands is satisfied that the requirements of the Companies Act (which includes certain other formalities) have been complied with, the Registrar of Companies of the Cayman Islands will register the plan of merger or consolidation.

After obtaining the relevant authorizations and consents, a director of each Cayman Islands company must sign the plan of merger or consolidation on behalf of their company and file the plan with the Registrar

TABLE OF CONTENTS

of Companies together with prescribed documents such as certificates of good standing, director’s declarations that, among other things: (a) the constituent company is, and the consolidated or surviving company will be, immediately after merger or consolidation, able to pay its debts as they fall due; (b) that the merger or consolidation is bona fide and not intended to defraud unsecured creditors of the constituent companies; and that (c)(i) no petition or other similar proceeding has been filed and remains outstanding or order made or resolution adopted to wind up the company in any jurisdiction; (iii) no receiver, trustee, administrator or other similar person has been appointed in any jurisdiction and is acting in respect of the constituent company, its affairs or its property or any part thereof; and (iv) no scheme, order, compromise or other similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of any constituent company are and continue to be suspended or restricted.

Where the merger or consolidation involves a foreign company and the surviving company is the foreign company, the procedure is similar, save that with respect to the foreign company, the directors of the Cayman Islands exempted company are required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the merger or consolidation is permitted or not prohibited by the constitutional documents of the foreign company and by the laws of the jurisdiction in which the foreign company is incorporated, and that those laws and any requirements of those constitutional documents have been or will be complied with; (ii) that no petition or other similar proceeding has been filed and remains outstanding or order made or resolution adopted to wind up or liquidate the foreign company in the jurisdiction in which the foreign company is existing; (iii) that no receiver, trustee, administrator or other similar person has been appointed in any jurisdiction and is acting in respect of the foreign company, its affairs or its property or any part thereof; and (iv) that no scheme, order, compromise or other similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of the foreign company are and continue to be suspended or restricted.

Where the surviving company is the Cayman Islands exempted company, in addition to the above declarations, the directors of the Cayman Islands exempted company are further required to make a declaration to the effect that, having made due enquiry, they are of the opinion that the requirements set out below have been met: (i) that the foreign company is able to pay its debts as they fall due and that the merger or consolidation is bona fide and not intended to defraud unsecured creditors of the foreign company; (ii) that in respect of the transfer of any security interest granted by the foreign company to the surviving or consolidated company (a) consent or approval to the transfer has been obtained, released or waived; (b) the transfer is permitted by and has been approved in accordance with the constitutional documents of the foreign company; and (c) the laws of the jurisdiction of the foreign company with respect to the transfer have been or will be complied with; (iii) that the foreign company will, upon the merger or consolidation becoming effective, cease to be incorporated, registered or exist under the laws of the relevant foreign jurisdiction; and (iv) that there is no other reason why it would be against the public interest to permit the merger or consolidation.

Where the above procedures are adopted, the Companies Act provides for a right of dissenting shareholders to be paid a payment of the fair value of their shares upon their dissenting to the merger or consolidation if they follow a prescribed procedure. In essence, that procedure is as follows: (a) the shareholder must give their written objection to the merger or consolidation to the constituent company before the vote on the merger or consolidation, including a statement that the shareholder proposes to demand payment for their shares if the merger or consolidation is authorized by the vote; (b) within 20 days following the date on which the merger or consolidation is approved by the shareholders, the constituent company must give written notice of such approval to each shareholder who made a written objection; (c) a shareholder must within 20 days following receipt of such notice from the constituent company, give the constituent company a written notice of their intention to dissent including, among other details, a demand for payment of the fair value of their shares; (d) within seven days following the date of the expiration of the period set out in paragraph (c) above or within seven days following the date on which the plan of merger or consolidation is filed, whichever is later, the constituent company, the surviving company or the consolidated company must make a written offer to each dissenting shareholder to purchase their shares at a price that the company determines is the fair value and if the company and the shareholder agree the price within 30 days following the date on which the offer was made, the company must pay the shareholder such amount; and (e) if the company and the shareholder fail to agree a price within such 30 day period, within 20 days following the date on which such 30 day period expires, the company (and any dissenting shareholder may) shall file a

TABLE OF CONTENTS

petition with the Cayman Islands courts to determine the fair value and such petition must be accompanied by a list of the names and addresses of the dissenting shareholders with whom agreements as to the fair value of their shares have not been reached by the company. At the hearing of that petition, the Cayman Islands court has the power to determine the fair value of the shares together with a fair rate of interest, if any, to be paid by the company upon the amount determined to be the fair value. Any dissenting shareholder whose name appears on the list filed by the company may participate fully in all proceedings until the determination of fair value is reached. These rights of a dissenting shareholder are not available in certain circumstances, for example, to dissenters holding shares of any class in respect of which an open market exists on a recognized stock exchange or recognized interdealer quotation system at the relevant date where the consideration for such shares are shares of any company listed on a national securities exchange or shares of the surviving or consolidated company.

Moreover, Cayman Islands law has separate statutory provisions that facilitate the reconstruction or amalgamation of companies in certain circumstances, that will generally be more suited for complex mergers or other transactions involving widely held companies. Such transactions, commonly referred to in the Cayman Islands as a “scheme of arrangement,” may be tantamount to a merger. In the event that a merger was sought pursuant to a scheme of arrangement (the procedures for which are more rigorous and take longer to complete than the procedures typically required to consummate a merger in the United States), the arrangement in question must be approved by (i) in respect a scheme of arrangement proposed between a company and its shareholders (or any class of shareholder), three fourths in value of the shareholders (or each class of shareholder) who attend and vote, either in person or by proxy, at a meeting (or meetings) convened for that purpose; or (ii) in respect of a scheme of arrangement proposed between a company and its creditors (or any class of creditors), a majority in number representing three fourths in value of the creditors (or each class of creditors) who attend and vote, either in person or by proxy, at a meeting (or meetings) convened for that purpose. The convening of the meetings and subsequently the terms of the arrangement must be sanctioned by the Cayman Islands court. While a dissenting shareholder would have the right to express to the Cayman Islands court the view that the scheme of arrangement should not be sanctioned, the Cayman Islands court may be expected to sanction the scheme of arrangement if it satisfies itself that:

•

the company is not proposing to act illegally or beyond the scope of its corporate authority and the statutory provisions as to majority vote have been complied with;

•

the shareholders have been fairly represented at the meeting in question;

•

the arrangement is such as a businessman would reasonably approve; and

•

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Act or that would amount to a “fraud on the minority.”

If a scheme of arrangement is sanctioned by the Cayman Islands court, the scheme of arrangement will be binding on all of the shareholders (or each class of shareholder) or creditors (or each class of creditor).

If a scheme of arrangement or takeover offer (as described below) is sanctioned by the Cayman Islands court, any dissenting shareholder would have no rights comparable to appraisal rights (providing rights to receive payment in cash for the judicially determined value of the shares), which would otherwise ordinarily be available to dissenting shareholders of United States corporations.

Squeeze-out Provisions

When a takeover offer is made and accepted by holders of not less than 90% of the shares to whom the offer relates within four months, the offeror may, within a two-month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Cayman Islands courts, but this is unlikely to succeed unless there is evidence of fraud, bad faith, collusion or inequitable treatment of the shareholders.

Further, transactions similar to a merger, reconstruction and/or an amalgamation may in some circumstances be achieved through means other than these statutory provisions, such as a share capital exchange, asset acquisition or control, or through contractual arrangements of an operating business.

TABLE OF CONTENTS

Shareholders’ Suits

Walkers (Cayman) LLP, our Cayman Islands legal counsel, is not aware of any reported class action having been brought in a Cayman Islands court. Derivative actions have been brought in the Cayman Islands courts, and the Cayman Islands courts have confirmed the availability for such actions. In most cases, we will be the proper plaintiff in any claim based on a breach of duty owed to us, and a claim against (for example) our officers or directors usually may not be brought by a shareholder. However, based both on Cayman Islands authorities and on English authorities, which would in all likelihood be of persuasive authority and be applied by a court in the Cayman Islands, exceptions to the foregoing principle apply in circumstances in which:

•

a company is acting, or proposing to act, illegally or beyond the scope of its authority;

•

the act complained of, although not beyond the scope of the authority, could be effected if duly authorized by more than the number of votes which have actually been obtained; or

•

those who control the company are perpetrating a “fraud on the minority.”

A shareholder may have a direct right of action against us where the individual rights of that shareholder have been infringed or are about to be infringed.

Enforcement of Civil Liabilities

The Cayman Islands has a different body of securities laws as compared to the United States and provides less protection to investors. Additionally, Cayman Islands companies may not have standing to sue before the Federal courts of the United States.

We have been advised by Walkers (Cayman) LLP, our Cayman Islands legal counsel, that the courts of the Cayman Islands are unlikely (i) to recognize or enforce against us judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state; and (ii) in original actions brought in the Cayman Islands, to impose liabilities against us predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

Special Considerations for Exempted Companies

We are an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary resident company except for the exemptions and privileges listed below:

•

an exempted company does not have to file an annual return of its shareholders with the Registrar of Companies of the Cayman Islands;

•

an exempted company’s register of members is not open to inspection;

•

an exempted company does not have to hold an annual general meeting;

•

an exempted company may issue shares with no par value;

TABLE OF CONTENTS

•

an exempted company may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 30 years in the first instance);

•

an exempted company may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

•

an exempted company may register as a limited duration company; and

•

an exempted company may register as a segregated portfolio company.

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Indemnification of Directors and Executive Officers and Limitation of Liability

Cayman Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against willful default, willful neglect, actual fraud or the consequences of committing a crime. Our Articles permit indemnification of officers and directors, to the fullest extent permitted under the laws of the Cayman Islands, for any liability and loss suffered and expenses, including legal expenses, incurred in their capacities as such in connection with any action, suit or proceeding, where civil, administrative or investigative. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we have entered into indemnification agreements with our directors that will provide such persons with additional indemnification beyond that provided in our Articles.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Directors’ Fiduciary Duties

Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself or herself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the corporation. A director must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

Under Cayman Islands law, directors and officers owe the following fiduciary duties:

•

duty to act in good faith in what the director or officer believes to be in the best interests of the company as a whole;

•

duty to exercise powers for the purposes for which those powers were conferred and not for a collateral purpose;

•

directors should not improperly fetter the exercise of future discretion;

TABLE OF CONTENTS

•

duty to exercise powers fairly as between different sections of shareholders;

•

duty not to put themselves in a position in which there is a conflict between their duty to the company and their personal interests; and

•

duty to exercise independent judgment.

In addition to the above, directors also owe a duty of care which is not fiduciary in nature. This duty has been defined as a requirement to act as a reasonably diligent person having both the general knowledge, skill and experience that may reasonably be expected of a person carrying out the same functions as are carried out by that director in relation to the company and the general knowledge skill and experience of that director.

As set out above, directors have a duty not to put themselves in a position of conflict and this includes a duty not to engage in self-dealing, or to otherwise benefit as a result of their position. However, in some instances what would otherwise be a breach of this duty can be forgiven and/or authorized in advance by the shareholders provided that there is full disclosure by the directors. This can be done by way of permission granted in the Articles or alternatively by shareholder approval at general meetings.

Shareholder Action by Written Consent

Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. The Articles provide that shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Shareholder Proposals

Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

The Companies Act provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company’s articles of association. The Articles provide that shareholders holding greater than an aggregate of 10.0% of the ordinary shares issued and outstanding of the Company (i) may call an extraordinary general meeting and put forth proposals at such extraordinary general meeting, and (ii) may put forth proposals at an annual general meeting, in each case subject to compliance with the relevant notice provisions in the Articles.

Cumulative Voting

Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. As permitted under Cayman Islands law, the Articles do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Removal of Directors

Under the Delaware General Corporation Law, a director of a corporation may be removed for cause with the approval of a majority of the issued and outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under the Articles, directors may be removed by the shareholders for “cause” (i.e., a conviction of a felony, the willful misconduct in the performance of director’s duties to the Company in a matter of substantial importance, or mental incompetency that directly affects such director’s

TABLE OF CONTENTS

ability to perform his or her obligations as a director) by an ordinary resolution. Directors other than Mr. Fitzpatrick may be removed by the shareholders without cause by an ordinary resolution. A director will also cease to be a director if he or she (i) becomes bankrupt or makes any arrangement or composition with his creditors; (ii) dies or is found to be or becomes of unsound mind; (iii) resigns his office by notice in writing; (iv) is prohibited by applicable law from being a director; or (v) the director absents himself or herself (for the avoidance of doubt, without being represented by proxy) from meetings of the Board for six consecutive months without special leave of absence from the directors, and the directors pass a resolution that he or she has by reason of such absence vacated office.

Transactions with Interested Shareholders

The Delaware General Corporation Law contains a business combination statute applicable to Delaware corporations whereby, unless the corporation has specifically elected not to be governed by such statute under its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and for a proper corporate purpose and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; Winding Up

Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board.

Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Under the Articles, if the Company is wound up, the liquidator of our company may distribute the assets with the sanction of a special resolution of the shareholders and any other sanction required by law.

Variation of Rights of Shares

Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise.

TABLE OF CONTENTS

the consent in writing of the holders of not less than two thirds of the issued shares of that class or with the approval of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the shares of that class.

Amendment of Governing Documents

Under the Delaware General Corporation Law, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote on the matter, unless the certificate of incorporation provides otherwise. As permitted by Cayman Islands law, the Articles may only be amended by a special resolution of the shareholders.

Directors’ Power to Issue Shares

Subject to applicable law, our board of directors is empowered to issue or allot shares or grant options and warrants with or without preferred, deferred, or other rights or restrictions.

Inspection of Books and Records

Under the Delaware General Corporation Law, any shareholder of a corporation may for any proper purpose inspect or make copies of the corporation’s stock ledger, list of shareholders and other books and records.

Holders of our shares have no general right under Cayman Islands law to inspect or obtain copies of our register of members or our corporate records.

Waiver of Certain Corporate Opportunities

TABLE OF CONTENTS

DESCRIPTION OF PREFERRED SHARES

Our authorized share capital is $210,000 divided into 200,000,000 ordinary shares of a par value of $0.001 each and 10,000,000 preferred shares of a par value of $0.001 each. Our Articles provide that our Board may issue one or more series or preferred shares, with each of such series having such voting powers (full or limited or without voting powers), designations, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions as are stated and expressed in any resolution or resolutions of the Board providing for the issue of such series.

The particular terms of any issue of preferred shares will be described in the prospectus supplement relating to the issue. Those terms may include:

•

the title and number of preferred shares;

•

the issue price per preferred share (or if applicable, the calculation formula of the issue price per preferred share);

•

the dividend rate on the preferred shares, the dividend payment dates, the periods in respect of which dividends are payable, whether such dividends shall be cumulative and, if cumulative, the date or dates from which dividends shall accumulate;

•

whether the preferred shares shall be convertible into, or exchangeable for, ordinary shares or preferred shares of another category, and, if applicable, conditions of an automatic conversion into ordinary shares, if any, the conversion period, the conversion price, or how such price will be calculated, and under what circumstances it may be adjusted;

•

the liquidation preference per preferred share, if any;

•

voting rights, if any, of the preferred shares;

•

other restrictions on transfer, sale or assignment, if any;

•

a discussion of the material Cayman Islands or United States federal income tax considerations applicable to the preferred shares; and

•

any other specific terms, rights, preferences, privileges, qualifications or restrictions of the preferred shares.

When we issue preferred shares under this prospectus and the applicable prospectus supplement, the preferred shares will be fully paid and non-assessable and will not have, or be subject to, any pre-emptive or similar rights.

The issuance of preferred shares could adversely affect the voting power of holders of our ordinary shares and reduce the likelihood that holders of our ordinary shares will receive dividend payments and payments upon liquidation. The issuance could have the effect of decreasing the market price of our ordinary shares. The issuance of preferred shares also could delay, deter or prevent a change in control of the Company, or make removal of management more difficult. As of the date of this prospectus, there are no issued and outstanding preferred shares of any series.

DESCRIPTION OF WARRANTS

Issuable Warrants

We may issue warrants for the purchase of our ordinary shares. We may issue warrants independently or together with other securities, and the warrants may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and the investors or a warrant agent. The following summary of material provisions of the warrants and warrant agreements are subject to, and qualified in their entirety by reference to, all the provisions of the warrant agreement and warrant certificate applicable to a particular series of warrants. The terms of any warrants offered under a prospectus supplement may differ from the terms described below. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete warrant agreements and warrant certificates that contain the terms of the warrants.

The particular terms of any issue of warrants will be described in the prospectus supplement relating to the issue. Those terms may include:

•

the number of ordinary shares purchasable upon the exercise of warrants to purchase such shares and the price at which such number of shares may be purchased upon such exercise;

•

the date, if any, on and after which the warrants and the related ordinary shares will be separately transferable;

•

the terms of any rights to redeem or call the warrants;

•

the date on which the right to exercise the warrants will commence and the date on which the right will expire;

•

a discussion of the material Cayman Islands and United States federal income tax consequences applicable to the warrants; and

•

any additional terms of the warrants, including terms, procedures, and limitations relating to the exchange, exercise and settlement of the warrants.

Holders of equity warrants will not be entitled:

•

to vote, consent or receive dividends;

•

receive notice as shareholders with respect to any meeting of shareholders for the election of our directors or any other matter; or

•

exercise any rights as shareholders of Vertical.

Each warrant will entitle its holder to purchase the number of ordinary shares at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

A holder of warrant certificates may exchange them for new warrant certificates of different denominations, present them for registration of transfer and exercise them at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement. Until any warrants to purchase ordinary shares are exercised, the holders of the warrants will not have any rights of holders of the underlying ordinary shares, including any rights to receive dividends on the ordinary shares or payments upon any winding up, liquidation or dissolution of the Company, if any.

The warrants will be governed by, and construed in accordance with, the laws of the State of New York, excluding choice of law provisions.

TABLE OF CONTENTS

DESCRIPTION OF RIGHTS

The following summary description of the rights to subscribe for ordinary shares (the “Rights”), and any description of rights in the applicable prospectus supplement, does not purport to be complete and is subject to, and qualified in its entirety by reference to, the applicable rights agreement and provisions of the certificate evidencing the Rights that will be filed with the SEC in connection with the offering of such Rights.

The Company may issue Rights that the Company may offer to its securityholders from time to time. The Rights may or may not be transferable by the persons purchasing or receiving the Rights. In connection with any Rights offering, the Company may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such Rights offering.

Each series of Rights will be issued under a separate rights agent agreement to be entered into between the Company and a bank or trust company, as rights agent, that the Company will name in the applicable prospectus supplement. The rights agent will act solely as the Company’s agent in connection with the Rights and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of Rights.

The prospectus supplement relating to any Rights that the Company may offer from time to time will describe specific terms relating to the offering, including, among other matters:

•

the title of the Rights;

•

the date of determining the securityholders entitled to the Rights distribution;

•

the aggregate number of Rights issued and the aggregate number of ordinary shares purchasable upon exercise of the Rights;

•

the exercise price;

•

the date on which the Rights become exercisable and the date on which the Rights will expire;

•

the extent to which the Rights include an over-subscription privilege with respect to unsubscribed Securities;

•

if applicable, a discussion of the material Cayman Islands and/or United States federal income tax considerations applicable to the issuance or exercise of such Rights;

•

if applicable, the material terms of any standby underwriting or other purchase arrangement that the Company may enter into in connection with the Rights offering; and

•

the material terms of the Rights, including terms, transferability, conditions to completion of the Rights offering, procedures and limitation relating to the exchange and exercise of such Rights.

Each Right would entitle the holder of the Rights to subscribe for cash the principal amount of ordinary shares at the exercise price set forth in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the Rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised Rights will become void (unless subject to subscription by another third party pursuant to the terms of such rights offering as described in the relevant prospectus supplement).

If less than all of the Rights issued in any Rights offering are exercised, the Company may offer any unsubscribed Securities directly to persons other than the Company’s securityholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

We may issue units consisting of any combination of the other types of securities offered under this prospectus in one or more series. We may evidence each series of units by unit certificates that we will issue under a separate agreement. We may enter into unit agreements with a unit agent.

We will indicate the name and address of the unit agent in the applicable prospectus supplement relating to a particular series of units.

PLAN OF DISTRIBUTION

We may offer and sell the securities being offered hereby in one or more of the following ways from time to time:

•

through agents;

•

to or through underwriters;

•

on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

•

in the over-the-counter market;

•

in transactions other than on these exchanges or systems or in the over-the-counter market;

•

in “at the market offerings,” within the meaning of Rule 415(a)(4) under the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

directly by us or by selling securityholders to purchasers, including through a specific bidding, auction or other process;

•

privately negotiated transactions;

•

a combination of any of the above methods of sale; and

•

through any other method permitted pursuant to applicable law and described in a prospectus supplement.

We may also offer and sell, or agree to deliver, securities pursuant to, or in connection with, any option agreement or other contractual arrangement. The securities may be distributed from time to time in one or more transactions:

•

at a fixed price or prices, which may be changed;

•

at market prices prevailing at the time of sale;

•

at prices related to such prevailing market prices; or

•

at negotiated prices.

Each time that we sell securities covered by this prospectus, we will provide a prospectus supplement or supplements that will describe the method of distribution and set forth the terms and conditions of the offering of such securities, including the offering price of the securities and the proceeds to us, if applicable.

Offers to purchase the securities being offered by this prospectus may be solicited directly. Agents may also be designated to solicit offers to purchase the securities from time to time. Any agent involved in the offer or sale of our securities will be identified in a prospectus supplement.

If a dealer is utilized in the sale of the securities being offered by this prospectus, the securities will be sold to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale.

If an underwriter is utilized in the sale of the securities being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of any underwriter will be

TABLE OF CONTENTS

provided in the prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase securities as a principal, and may then resell the securities at varying prices to be determined by the dealer.

One or more firms, referred to as “remarketing firms,” may also offer or sell the securities, if a prospectus supplement so indicates, in connection with a remarketing arrangement upon their purchase. Remarketing firms will act as principals for their own accounts or as our agents. These remarketing firms will offer or sell the securities in accordance with the terms of the securities. Each prospectus supplement will identify and describe any remarketing firm and the terms of its agreement, if any, with us and will describe the remarketing firm’s compensation. Remarketing firms may be deemed to be underwriters in connection with the securities they remarket. Remarketing firms may be entitled under agreements that may be entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

Any compensation paid to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

Any ordinary shares will be listed on NYSE, but any other securities may or may not be listed on a national securities exchange. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involve the sale by persons participating in the offering of more securities than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

We may engage in at the market offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement so indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of shares, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of shares. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be named in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus and an applicable prospectus supplement. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

TABLE OF CONTENTS

We may effect sales of securities in connection with forward sale, option or other types of agreements with third parties. Any distribution of securities pursuant to any forward sale agreement may be effected from time to time in one or more transactions that may take place through a stock exchange, including block trades or ordinary broker’s transactions, or through broker-dealers acting either as principal or agent, or through privately negotiated transactions, or through an underwritten public offering, or through a combination of any such methods of sale, at market prices prevailing at the time of sale, prices relating to such prevailing market prices or at negotiated or fixed prices.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.

The expenses of any offering of our securities will be detailed in the applicable prospectus supplement. The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business for which they receive compensation.

We will identify the specific plan of distribution, including any agents, underwriters, dealers, remarketing firms or other third parties and their compensation in a prospectus supplement.

The validity of the ordinary shares and the preferred shares being registered hereby and certain other matters of Cayman Islands law will be passed upon for us by Walkers (Cayman) LLP.

EXPERTS

The financial statements incorporated in this prospectus by reference to the Annual Report on Form 20-F for the year ended December 31, 2024 have been so incorporated in reliance on the report (which contains an explanatory paragraph relating to the Company’s ability to continue as a going concern as described in Note 2 to the financial statements) of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

The registered address of PricewaterhouseCoopers LLP is 1 Embankment Place, London WC2N 6RH, United Kingdom.

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the Cayman Islands. Service of process upon us and upon our directors and officers and the Cayman Islands experts named in this prospectus, substantially all of whom reside outside the United States, may be difficult to obtain within the United States. Furthermore, because substantially all of our assets and substantially all of our directors and officers are located outside the United States, any judgment obtained in the United States against us or any of our directors and officers may not be collectible within the United States.

We have irrevocably appointed Cogency Global Inc. as our agent to receive service of process in any action against us in any U.S. federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering. The address of our agent is 122 E 42nd St., 18th Floor, New York, New York 10168.

We have been advised by our Cayman Islands legal counsel, Walkers (Cayman) LLP, that the courts of the Cayman Islands are unlikely (i) to recognize or enforce against us judgments of courts of the United States predicated upon the civil liability provisions of the securities laws of the United States or any State; and (ii) in original actions brought in the Cayman Islands, to impose liabilities against us predicated upon the civil liability provisions of the securities laws of the United States or any State, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.
