PROSPECTUS

$300,000,000

TortoiseEcofin Acquisition Corp. III

30,000,000 Class A Ordinary Shares

______________________________________

TortoiseEcofin Acquisition Corp. III is a blank check company newly incorporated as a Cayman Islands exempted company for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities, which we refer to throughout this prospectus as our initial business combination. We have not selected any business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target. We intend to focus our search for a target business in the broad energy transition or sustainability arena targeting industries that require innovative solutions to decarbonize in order to meet critical emission reduction objectives.

This is an initial public offering of our Class A ordinary shares, par value $0.0001 per share, which we refer to as our public shares. Each Class A ordinary share has an offering price of $10.00. We have also granted the underwriters a 45-day option to purchase up to an additional 4,500,000 Class A ordinary shares to cover over-allotments, if any. Unlike other initial public offerings of special purpose acquisition companies, investors in this offering will not receive any warrants (which would typically become exercisable following completion of our initial business combination).

We will provide our public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account described below as of two business days prior to the consummation of our initial business combination, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding Class A ordinary shares that were sold, subject to the limitations described herein. If we are unable to complete our initial business combination within 24 months from the closing of this offering, or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering but have not completed the initial business combination within such 24-month period, we will redeem 100% of the public shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, subject to applicable law and as further described herein.

Tortoise has committed to purchase an aggregate of 950,000 Class A ordinary shares (or 1,040,000 Class A ordinary shares if the over-allotment option is exercised in full) at a price of $10.00 per share (approximately $9,500,000 in the aggregate, or approximately $10,400,000 in the aggregate if the over-allotment option is exercised in full) in a private placement that will close simultaneously with the closing of this offering. We refer to these shares throughout this prospectus as the private placement shares. The private placement shares are identical to the Class A ordinary shares sold in this offering, subject to certain limited exceptions as described in this prospectus.

Our sponsor, TortoiseEcofin Sponsor III LLC (which we refer to as our sponsor throughout this prospectus), owns an aggregate of 8,625,000 Class B ordinary shares (up to 1,125,000 shares of which are subject to forfeiture depending on the extent to which the underwriters’ over-allotment option is exercised). We refer to these Class B ordinary shares as the founder shares throughout this prospectus. The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of our initial business combination on a one-for-one basis, subject to adjustment as provided herein. Holders of the Class B ordinary shares will have the right to appoint all of our directors prior to our initial business combination. On any other matter submitted to a vote of our shareholders, holders of the Class B ordinary shares and holders of the Class A ordinary shares will vote together as a single class, except that in respect of any vote or votes to continue the company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction), holders of Class B ordinary shares will have ten votes per share and holders of Class A ordinary shares will have one vote per share, and except as required by law or the applicable rules of the New York Stock Exchange (the “NYSE”) then in effect.

Currently, there is no public market for our Class A ordinary shares. We intend to apply to have our Class A ordinary shares listed on the NYSE under the symbol “TRTL” on or promptly after the date of this prospectus. We cannot guarantee that our Class A ordinary shares will be approved for listing on the NYSE.

We are an “emerging growth company” and a “smaller reporting company” under applicable federal securities laws and will be subject to reduced public company reporting requirements. Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 28 for a discussion of information that should be considered in connection with an investment in our securities. Investors will not be entitled to protections normally afforded to investors in Rule 419 blank check offerings.

Neither the SEC nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

No offer or invitation to subscribe for securities may be made to the public in the Cayman Islands.

(1) Includes $0.35 per share, or $10,500,000 in the aggregate (or $12,075,000 in the aggregate if the underwriters’ over-allotment option is exercised in full), payable to the underwriters for deferred underwriting discounts and commissions to be placed in a trust account located in the United States as described herein and released to the underwriters only upon the completion of an initial business combination, as described in this prospectus. See “Underwriting” beginning on page 148 for a description of compensation and other items of value payable to the underwriters.

(2) At our request, the underwriters have agreed to reserve up to 100,000 of the Class A ordinary shares offered by this prospectus for sale to certain members of Tortoise, at the initial public offering price. We call this our Directed Shares Program. Sales in the Directed Shares Program will be made at our direction by Goldman Sachs & Co. LLC. The underwriters will receive the same underwriting discount on any shares purchased pursuant to this program as they will on any other shares sold to the public in this offering. We do not know if individual investors will choose to purchase all or any portion of these reserved Class A ordinary shares, but any purchases they do make will reduce the number of Class A ordinary shares available in the overall offering. This table assumes that no Class A ordinary shares are sold in the Directed Shares Program. Any reserved Class A ordinary shares not purchased in the Directed Shares Program will be offered by the underwriters to the general public on the same terms as the other Class A ordinary shares.

Of the approximately $309.5 million in proceeds we receive from this offering and the sale of the private placement shares described in this prospectus, or approximately $355.4 million if the underwriters’ over-allotment option is exercised in full, $300.0 million ($10.00 per share), or approximately $345.0 million if the underwriters’ over-allotment option is exercised in full ($10.00 per share), will be deposited into a U.S.-based trust account at J.P. Morgan Chase Bank, N.A., with Continental Stock Transfer & Trust Company acting as trustee, and approximately $9.5 million, including approximately $6.0 million in underwriting discounts and commissions (or approximately $10.4 million, including approximately $6.9 million in underwriting discounts and commissions, if the underwriters’ over-allotment option is exercised in full), will be used to pay fees and expenses in connection with the closing of this offering and for working capital following the closing of this offering. Except with respect to interest earned on the funds held in the trust account that may be released to us to pay our taxes, the proceeds from this offering and the sale of the private placement shares held in the trust account will not be released from the trust account until the earliest of (a) the completion of our initial business combination (including the release of funds to pay any amounts due to any public shareholders who properly exercise their redemption rights in connection therewith), (b) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering and (c) the redemption of our public shares if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law. The proceeds deposited in the trust account could become subject to the claims of our creditors, if any, which could have priority over the claims of our public shareholders.

The underwriters are offering the Class A ordinary shares for sale on a firm commitment basis. The underwriters expect to deliver the Class A ordinary shares to the purchasers on or about , 2021.

Our Company

We are a blank check company newly incorporated as a Cayman Islands exempted company for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities, which we refer to throughout this prospectus as our initial business combination. We have not selected any business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target. We intend to focus our search for a target business in the broad energy transition or sustainability arena targeting industries that require innovative solutions to decarbonize in order to meet critical emission reduction objectives. The Intergovernmental Panel on Climate Change estimates that limiting global warming to 1.5 degrees Celsius above pre-industrial temperatures will require annual investments of $1.6 — $3.8 trillion in the global supply-side energy system through 2050, with some climate scenarios requiring net-zero global emissions by 2050, resulting in the need for high-growth energy transition and technology solutions. In light of this and other developments fostering a sense of urgency and responsibility, as of February 2021, more than 1,000 companies worldwide are leading the zero-carbon transition by setting emissions reduction targets through the Science Based Targets initiative (SBTi). We believe our management team, together with the broader Tortoise Ecofin Platforms, which are affiliates of our sponsor, are well suited to identify opportunities that create a positive environmental impact, exhibit strong Environmental, Social and Governance (“ESG”) attributes and have the potential to generate attractive risk-adjusted returns for our shareholders, although we may pursue a business combination opportunity in any business or industry.

Our management team and an affiliate of Tortoise co-founded Tortoise Acquisition Corp. (“Tortoise Acquisition I”; NYSE: SHLL), a special purpose acquisition company that completed its initial public offering in March 2019, in which it sold 23,300,917 units, each consisting of one share of Class A common stock and one-half of one warrant, with each whole warrant entitling the holder thereof to purchase one share of Class A common stock, for an offering price of $10.00 per unit, generating aggregate proceeds of approximately $233 million. In October 2020, Tortoise Acquisition I consummated its initial business combination with Hyliion Inc., a Delaware corporation (“Hyliion”), a leader in electrified powertrain solutions for Class 8 commercial vehicles. The combined entity, Hyliion Holdings Corp., is listed on the NYSE under the ticker symbol “HYLN.”

Our management team and an affiliate of Tortoise co-founded Tortoise Acquisition Corp. II (“Tortoise Acquisition II”; NYSE: SNPR), a special purpose acquisition company that completed its initial public offering in September 2020, in which it sold 34,500,000 units, each consisting of one Class A ordinary share and one-fourth of one warrant, with each whole warrant entitling the holder thereof to purchase one Class A ordinary share, for an offering price of $10.00 per unit, generating aggregate proceeds of approximately $345 million. In February 2021, Tortoise Acquisition II announced its initial business combination with Volta Industries, Inc., a Delaware corporation (“Volta”), a leading owner-operator of public electric vehicle charging infrastructure. The combined entity, Volta Inc., is expected to be listed on the NYSE under the ticker symbol “VLTA.”

Table of Contents

We believe that we will benefit from the valuable experience gained by our management team during the launch and operation of Tortoise Acquisition II and Tortoise Acquisition I, including the process of evaluating numerous target companies and industry sectors, selecting Volta and Hyliion as business combination partners, negotiating the terms of the business combination agreements and all of the related financing transactions and, in the case of Tortoise Acquisition I, soliciting stockholder approval and consummating the business combination and the related transactions. See “Past performance by our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, the Tortoise Funds, Lightfoot Capital and any related investment may not be indicative of future performance of an investment in us” and other risk factors described in the “Risk Factors” section for more information.

Our extensive sourcing network includes (i) business founders, owners and senior management contacts, (ii) private equity, financial investors and other sponsors of private businesses and (iii) industry professionals, including investment banking, legal, accounting and other industry focused experts. We believe that there are highly attractive investment opportunities that are accessible through our network of contacts which exist within our focus industries and also exhibit strong ESG profiles. We believe our management team’s experience and combined expertise provide us with unique insight to evaluate targets across numerous sectors, including clean and renewable energy and related infrastructure, electric and autonomous mobility, energy efficiency and battery storage solutions, environmental services, hydrogen, renewable and bio fuels, and waste to energy and recycling, among others. Businesses that we plan to target for our initial business combination will be those that are at an inflection point in their life cycle and that we believe can benefit from our strategic insights, capital and expertise to accelerate their business development, improve their business prospects and unlock the full value of their businesses.

We believe in the ability of our management team to add significant value to a target company from a business building, commercial, capital markets and sustainability perspective. Our extensive operational experience and the public company expertise of our management team present the potential for an attractive risk-adjusted return profile through our involvement and stewardship. As demonstrated by our management team with Tortoise Acquisition II’s announced business combination with Volta and Tortoise Acquisition I’s consummated business combination with Hyliion, we believe that the extensive skills and perspectives of our management team will enable us to identify dynamic and visionary management teams and work alongside them to crystalize their strategic vision, enhance their business plan and improve their operational capabilities. In addition, our team has significant hands-on experience working with growth-oriented companies in preparing for and executing an initial public offering or an initial business combination, and serving as active owners and directors by working closely with these companies to assist in the execution of their strategic plan, support their continued transformations and help access and create value in the public markets.

We believe we play an important role in the public equity markets by identifying high-quality, growth-oriented businesses, evaluating the merits and viability of high-growth business plans and completing pre-investment due diligence, focusing and preparing the business for the multi-faceted requirements of being a publicly traded company, and both capitalizing and leading the actual business combination transaction. This function will be invaluable to our eventual business combination target, as we have the skills to validate and enhance their business plan, improve their ESG profile and prepare them for the rigors of being publicly listed, as well as to our investors who might otherwise not have the opportunity or confidence to publicly invest in the business we identify in the transition towards a decarbonized and cleaner future.

Management, Our Sponsor and Board of Directors

We will be led by our co-founder Vincent Cubbage, who serves as our Chief Executive Officer and Chairman of the Board and has over 26 years of investment experience. Mr. Cubbage co-founded and currently serves as Chief Executive Officer, President and Chairman of the Board of Tortoise Acquisition II and is expected to serve on the board of directors of the combined entity following the closing of its business combination with Volta. Mr. Cubbage also co-founded and served as Chief Executive Officer, President and Chairman of the Board of Tortoise Acquisition I and continues to serve on the board of directors of Hyliion Holdings Corp. following the closing of Tortoise Acquisition I’s business combination with Hyliion. Mr. Cubbage joined Tortoise Capital Advisors, L.L.C. in January 2019 and is a Managing Director on the Private Energy Transition team. Prior to joining Tortoise Capital Advisors, L.L.C., Mr. Cubbage founded private equity firm Lightfoot Capital Partners LP (together with its general partner, “Lightfoot Capital”) in 2006 and served as its Chief Executive Officer and Managing Partner from 2006 to 2019. Mr. Cubbage also served as the Chief Executive Officer and Chairman of the Board of Arc Logistics GP LLC,

Table of Contents

the general partner of Arc Logistics Partners LP (NYSE: ARCX) (together with its general partner, “Arc Logistics”), a portfolio company formed by Lightfoot Capital in 2007 and sold in 2017. Prior to founding Lightfoot Capital, Mr. Cubbage was an investment banker and, among other positions, was a Senior Managing Director and sector head in the Investment Banking Division of Banc of America Securities (“Banc of America Securities”).

Our management team will include all of the members of the management team of Tortoise Acquisition II and Tortoise Acquisition I. Mr. Stephen Pang serves as our President and Chief Financial Officer and as a Director on our Board. He currently serves as Chief Financial Officer and a board member of Tortoise Acquisition II. He served as Chief Financial Officer and a board member of Tortoise Acquisition I and continues to serve on the board of directors of Hyliion Holdings Corp. following the closing of Tortoise Acquisition I’s business combination with Hyliion. Mr. Pang is a Managing Director on the Private Energy Transition team at Tortoise Capital Advisors, L.L.C. and is responsible for the firm’s public and private direct investments, including private investment in public equities (“PIPEs”). Throughout its history, Tortoise Capital Advisors, L.L.C. has been involved in over 85 PIPEs across various investment vehicles. Mr. Darrell Brock serves as our Vice President of Business Development and Mr. Steven Schnitzer serves as our Vice President, General Counsel and Secretary, each of whom currently serves in the same capacities for Tortoise Acquisition II and previously, for Tortoise Acquisition I. Mr. Evan Zimmer serves as our Vice President of Finance and currently serves in the same capacity for Tortoise Acquisition II. In addition, Mr. Evan Zimmer was an employee of Tortoise who was dedicated to the business combination activities of Tortoise Acquisition I. Messrs. Brock, Schnitzer and Zimmer served in similar capacities at Lightfoot Capital and Arc Logistics under Mr. Cubbage’s leadership. The members of our entire management team have extensive experience identifying, evaluating, negotiating and completing the types of transactions that we plan to pursue for our initial business combination.

We will further be supported by our board of directors, comprised of senior leaders who have been at the forefront of forward thinking on climate change, sustainability policies and companies leading the transition to a cleaner future. They come from a wide range of sub-sectors and functional areas and will provide us with access to their expertise and extensive industry networks from which we intend to source and evaluate targets as well as devise plans to optimize any business that we acquire.

Our management team will also draw upon the resources and support of the broader Tortoise Ecofin Platforms, which brings decades of investing expertise in the areas of sustainability, energy transition, infrastructure, water and clean energy. Founded in 2002, Tortoise has a family of investment funds with over $8.2 billion of assets under management as of March 31, 2021. Tortoise has built a successful track record through a disciplined investment framework, with expertise that spans across the entire energy value chain in addition to sustainable infrastructure, including wind, solar and battery storage assets and social infrastructure. Tortoise is a signatory to the United Nations’ Principles for Responsible Investment and incorporates United Nations Sustainable Development Goals (“SDGs”) and ESG factor analysis into its investment strategy, policies and practices firmwide. Tortoise’s “Teal Energy Deal” promotes a reduction in carbon emissions globally by adopting a transition to a cleaner energy future. The Teal Energy Deal principally aligns with the following four SDGs: (1) No poverty; (7) Affordable and Clean Energy; (9) Industry, Innovation and Infrastructure; and (13) Climate Action.

We believe that potential sellers of target businesses will view the fact that our management team has successfully negotiated a business combination with Volta and consummated a business combination with Hyliion as positive factors in considering whether or not to enter into and consummate a business combination with us. However, past performance of our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise or Lightfoot Capital is not a guarantee either (i) of success with respect to any business combination we may consummate or (ii) that we will be able to identify a suitable candidate for our initial business combination. You should not rely on the historical record of our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, Lightfoot Capital or any related investment’s performance as indicative of our future performance.

Business Strategy

Our acquisition strategy is to identify and complete our initial business combination with a company that is playing an active role in providing solutions to reduce emissions and/or improve the sustainability of products and industries, along with making a positive impact on the communities that it serves by employing efficient and innovative business practices. We intend to target a company and management team that shares our commitment to good governance and transparency.

Table of Contents

We believe our management team’s track record and execution experience, including its experience sourcing Volta for Tortoise Acquisition II and Hyliion for Tortoise Acquisition I and consummating a business combination with Hyliion, together with the deep industry and investing experience of our sponsor combined with the extensive experience of our Chief Executive Officer and management team, make us very well positioned to identify, source, negotiate and execute a business combination that meets our investment criteria and generates attractive risk-adjusted returns for our shareholders. See “Past performance by our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, the Tortoise Funds, Lightfoot Capital and any related investment may not be indicative of future performance of an investment in us” and other risk factors described in the “Risk Factors” section for more information.

Our management team and the investment professionals of our sponsor have an extensive network of senior industry contacts, including corporate executives, investment banking professionals, private equity and other financial sponsors, and owners of private businesses. In addition, Tortoise has a long history of partnering with leading public and private equity investors. We believe this network is a key competitive advantage in sourcing attractive business combination targets that meet our criteria, and that the reputation and expertise of our management team and Tortoise around energy transition and sustainability themes will make us a preferred partner for potential business combination counterparties.

Our management team brings a diversity of transactional and investing experience that will enable us to evaluate opportunities across multiple sectors. Throughout his long career, including as Chief Executive Officer of Tortoise Acquisition II and Tortoise Acquisition I, investment banker, Chief Executive Officer and Managing Partner of Lightfoot Capital and Chief Executive Officer and Chairman of the Board of NYSE-listed Arc Logistics, our Chief Executive Officer oversaw the evaluation of hundreds of acquisitions and investments. As a Managing Director and Portfolio Manager at Tortoise Capital Advisors, L.L.C., Mr. Pang has evaluated and made numerous portfolio company investments across a broad platform of industry sectors and strategies. We believe the breadth of Tortoise’s and Messrs. Cubbage’s and Pang’s investment experience across multiple sub-sectors is a competitive advantage.

We believe that the operational experience of our management team should enable us to enhance the strategic vision and operational performance of the assets and businesses that we acquire in order to maximize value for shareholders. This may include improving operating efficiencies, increasing margins and profitability, driving revenue growth, investing in organic growth projects, pursuing future strategic acquisitions or divestitures and optimizing the capital structure. We believe our expertise in identifying and sourcing compelling investment opportunities combined with our strategic and operational proficiency in creating value provides a competitive advantage relative to other strategic and financial buyers.

Our management team and sponsor have a deep understanding of capital markets, which we believe is an important aspect of a special purpose acquisition company management team. We believe our Chief Executive Officer’s and our Chief Financial Officer’s extensive track records of public and private investments, including PIPEs, provide valuable expertise in evaluating and executing capital markets transactions. We believe that the combination of our management team’s experience and network in the private and public equity markets, together with the resources of the broader Tortoise Ecofin Platforms, will allow us to effectively identify, evaluate, finance and structure the business combination transaction.

We believe that our proven, differentiated and disciplined approach to sourcing, analyzing and ultimately executing an initial business combination enables us to find targets with attractive risk-adjusted return profiles for our shareholders. We have core investing tenets that guide our rigorous evaluations and commit to turning down opportunities that don’t satisfy our risk-adjusted return framework.

As outlined above, we have an integrated team with a full suite of strategic, financial, legal and operational capabilities, allowing us to identify targets and complete our due diligence in a thorough and expedited manner. We believe our integrated team and affiliation with Tortoise will also allow us to pursue a number of transaction opportunities concurrently and compress the time required from initial identification of an opportunity to transaction announcement.

Business Combination Criteria

Consistent with our business strategy, we have identified the following general criteria and guidelines that we believe are important in evaluating candidates for our initial business combination. We will use these criteria and guidelines in evaluating business combination opportunities, but we may decide to enter into our initial business combination with a target business that does not meet these criteria and guidelines. We intend to focus on candidates that we believe:

• will benefit from our team’s operating expertise, technical expertise, structuring expertise, extensive network, insight and capital markets expertise;

• exhibit unrecognized value or other characteristics, desirable returns on capital, and a need for capital to achieve the company’s growth strategy, that we believe have been misevaluated by the marketplace based on our analysis and due diligence review;

• are at an inflection point, are in need of additional management expertise, are able to innovate through new operational techniques, or where we believe we can drive improved financial performance;

• have attractive opportunities to grow the business through organic growth projects and third-party acquisitions;

• will be well received by public investors and are expected to have good access to the public capital markets;

• are engaged in activities that are consistent with Tortoise’s and management’s view of macro trends; and

• are expected to generate attractive risk-adjusted returns for our shareholders.

These criteria are not intended to be exhaustive. Any evaluation relating to the merits of a particular initial business combination may be based, to the extent relevant, on these general guidelines as well as other considerations, factors and criteria that our management may deem relevant. In the event that we decide to enter into our initial business combination with a target business that does not meet the above criteria and guidelines, we will disclose that the target business does not meet the above criteria in our shareholder communications related to our initial business combination, which, as discussed in this prospectus, would be in the form of proxy solicitation materials or tender offer documents that we would file with the U.S. Securities and Exchange Commission (the “SEC”).

Initial Business Combination

The NYSE rules require that we must complete one or more business combinations having an aggregate fair market value of at least 80% of the net assets held in trust (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time of the agreement to enter into the initial business combination. Our board will make the determination as to the fair market value of a target business or businesses. If our board is not able to independently determine the fair market value of a target business or businesses, we will obtain an opinion from an independent investment banking firm that is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”) or an independent accounting firm with respect to the satisfaction of such criteria. While we consider it unlikely that our board will not be able to make an independent determination of the fair market value of a target business or businesses, it may be unable to do so if the board is less familiar or experienced with the target company’s business or there is a significant amount of uncertainty as to the value of the company’s assets or prospects.

such co-investors, the need for additional capital beyond the amount held in our trust account to fund the business combination transaction and/or the desire to obtain committed capital for closing the business combination transaction. An Affiliated Joint Acquisition may be effected through a co-investment with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the business combination by issuing to such parties a class of equity or equity-linked securities. We refer to this potential future issuance, or a similar issuance to other specified purchasers, as a “specified future issuance” throughout this prospectus. The amount and other terms and conditions of any such specified future issuance would be determined at the time thereof. We are not obligated to make any specified future issuance and may determine not to do so. This is not an offer for any specified future issuance. Pursuant to the anti-dilution provisions of our Class B ordinary shares, any such specified future issuance would result in an adjustment to the conversion ratio such that our initial shareholders and their permitted transferees, if any, would retain their aggregate percentage ownership at 20% of the sum of the total number of all ordinary shares outstanding upon completion of this offering plus all shares issued in the specified future issuance (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the business combination and the private placement shares), unless the holders of a majority of the then-outstanding Class B ordinary shares agreed to waive such adjustment with respect to the specified future issuance at the time thereof. We cannot determine at this time whether a majority of the holders of our Class B ordinary shares would then agree to so waive such adjustment to the conversion ratio. They may waive such adjustment due to (but not limited to) the following: (i) closing conditions which are part of the agreement for our initial business combination; (ii) negotiation with Class A shareholders on structuring an initial business combination; (iii) negotiation with parties providing financing which would trigger the anti-dilution provisions of the Class B ordinary shares; or (iv) as part of the Affiliated Joint Acquisition. If such adjustment is not waived, the specified future issuance would not reduce the percentage ownership of holders of our Class B ordinary shares, but would reduce the percentage ownership of holders of our Class A ordinary shares. If such adjustment is waived, the specified future issuance would reduce the percentage ownership of holders of both classes of our ordinary shares.

We anticipate structuring our initial business combination either (i) in such a way so that the post-transaction company in which our public shareholders own shares will own or acquire 100% of the equity interests or assets of the target business or businesses or (ii) in such a way so that the post-transaction company owns or acquires less than 100% of such interests or assets of the target business in order to meet certain objectives of the target management team or shareholders or for other reasons, including an Affiliated Joint Acquisition as described above. However, we will only complete a business combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise is not required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Even if the post-transaction company owns or acquires 50% or more of the voting securities of the target, our shareholders prior to the business combination may collectively own a minority interest in the post-transaction company, depending on valuations ascribed to the target and us in the business combination transaction. For example, we could pursue a transaction in which we issue a substantial number of new shares in exchange for all of the outstanding capital stock, shares or other equity interests of a target. In this case, we would acquire a 100% controlling interest in the target. However, as a result of the issuance of a substantial number of new shares, our shareholders immediately prior to our initial business combination could own less than a majority of our outstanding shares subsequent to our initial business combination. If less than 100% of the equity interests or assets of a target business or businesses are owned or acquired by the post-transaction company, the portion of such business or businesses that is owned or acquired is what will be valued for purposes of the 80% of net assets test. If the business combination involves more than one target business, the 80% of net assets test will be based on the aggregate value of all of the transactions, and we will treat the target businesses together as the initial business combination for purposes of a tender offer or for seeking shareholder approval, as applicable.

Our Business Combination Process

In evaluating prospective business combinations, we expect to conduct a thorough due diligence review process. This due diligence review process will be specific to the target business, but will include, among other things, a review of historical and projected financial and operating data, meetings with management and their financial sponsors (if applicable), an assessment of the commodity price risk of the business and our ability to mitigate such risks with hedges, on-site inspection of assets, discussion with customers, legal and environmental reviews and other reviews as we deem appropriate. We will also utilize our expertise and Tortoise’s expertise operating companies and evaluating operating projections, financial projections and determining the appropriate return expectations given the risk profile of the target business.

Table of Contents

We are not prohibited from pursuing an initial business combination with a company that is affiliated with Tortoise or our officers or directors. In the event we seek to complete our initial business combination with a company that is affiliated with Tortoise or our officers or directors, we, or a committee of independent directors, will obtain an opinion from an independent investment banking firm which is a member of FINRA or an independent accounting firm that our initial business combination is fair to our company from a financial point of view.

Members of our management team and our independent directors will directly or indirectly own founder shares and/or private placement shares following this offering and, accordingly, may have a conflict of interest in determining whether a particular target business is an appropriate business with which to effectuate our initial business combination. Further, each of our officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers and directors were to be included by a target business as a condition to any agreement with respect to our initial business combination.

All of the members of our management team are employed by Tortoise or affiliates of Tortoise. Tortoise and its affiliates are continuously made aware of potential business opportunities, one or more of which we may desire to pursue for a business combination; we have not, however, selected any specific business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target.

Tortoise and each of our officers and directors presently has, and any of them in the future may have additional, fiduciary or contractual obligations to other entities pursuant to which such officer or director is or will be required to present a business combination opportunity. For example, Tortoise and certain of its officers currently are obligated by contract to offer or allocate certain investment opportunities first to specific private funds managed by them. Additionally, certain of our officers and directors currently serve in similar roles for Tortoise Acquisition II, a blank check company incorporated as a Cayman Islands exempted company and formed for the purpose of effecting its own initial business combination. Vince Cubbage is the Chief Executive Officer, President and Chairman of the Board of directors of Tortoise Acquisition II, Stephen Pang is the Chief Financial Officer and a director of Tortoise Acquisition II and Darrell Brock, Evan Zimmer and Steven Schnitzer are, respectively, Vice President, Business Development, Vice President, Finance and Vice President, General Counsel and Secretary of Tortoise Acquisition II, and each such officer and director owes fiduciary duties under Cayman Islands law to Tortoise Acquisition II. Upon the consummation of the business combination with Volta, Mr. Cubbage is expected to serve on the board of directors of the combined entity.

Accordingly, if any of our officers or directors becomes aware of a business combination opportunity which is suitable for an entity to which he or she has then-current fiduciary or contractual obligations, he or she will honor his or her fiduciary or contractual obligations to present such opportunity to such entity. We believe, however, that the fiduciary duties or contractual obligations of Tortoise and our officers or directors will not materially affect our ability to complete our initial business combination. In addition, we may, at our option, pursue an Affiliated Joint Acquisition opportunity with an entity to which Tortoise or an officer or director has a fiduciary or contractual obligation. Any such entity may co-invest with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the business combination by making a specified future issuance to any such entity. Our amended and restated memorandum and articles of association will provide that we renounce our interest in any corporate opportunity offered to any director or officer unless such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of our company and such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue, and to the extent the director or officer is permitted to refer that opportunity to us without violating another legal obligation.

Our sponsor, members of our management team or their affiliates may sponsor other special purpose acquisition companies similar to ours during the period in which we are seeking an initial business combination and our officers and directors may become an officer or director of any other special purpose acquisition company with a class of securities registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), even before we have entered into a letter of intent, agreement in principle or definitive agreement regarding our initial business combination. Any such companies may present additional conflicts of interest in pursuing an acquisition target, particularly in the event there is an overlap among the management teams. For more information, see “Management — Conflicts of Interest.”

We will have three independent directors upon completion of this offering. An “independent director” is defined generally as a person other than an officer or employee of the company or its subsidiaries or any other individual having a relationship which, in the opinion of the company’s board of directors, would interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director.

Prior to the effectiveness of the registration statement of which this prospectus forms a part, we will file a Registration Statement on Form 8-A with the SEC to voluntarily register our securities under Section 12 of the Exchange Act. As a result, we will be subject to the rules and regulations promulgated under the Exchange Act. We have no current intention of filing a Form 15 to suspend our reporting or other obligations under the Exchange Act prior or subsequent to the consummation of our initial business combination.

Unlike other initial public offerings of special purpose acquisition companies, investors in this offering will not receive any warrants (which would typically become exercisable following completion of our initial business combination).

Corporate Information

Our executive offices are located at 5100 W. 115th Place, Leawood, KS 66211, and our telephone number is (913) 981-1020. Upon completion of this offering, our corporate website address will be www.tortoisespac.com. Our website and the information contained on, or that can be accessed through, the website is not deemed to be incorporated by reference in, and is not considered part of, this prospectus. You should not rely on any such information in making your decision whether to invest in our securities.

We are a Cayman Islands exempted company. Exempted companies are Cayman Islands companies conducting business mainly outside the Cayman Islands and, as such, are exempted from complying with certain provisions of the Companies Act. As an exempted company, we have applied for and received a tax exemption undertaking from the Cayman Islands government that, in accordance with the Tax Concessions Act (2018 Revision) of the Cayman Islands, for a period of 30 years from the date of the undertaking, no law which is enacted in the Cayman Islands imposing any tax to be levied on profits, income, gains or appreciations will apply to us or our operations and, in addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax will be payable (i) on or in respect of our shares, debentures or other obligations or (ii) by way of the withholding in whole or in part of a payment of dividends or other distribution of income or capital by us to our shareholders or a payment of principal or interest or other sums due under a debenture or other obligation of us.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. If some investors find our securities less attractive as a result, there may be a less active trading market for our securities and the prices of our securities may be more volatile.

In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We intend to take advantage of the benefits of this extended transition period.

We will remain an emerging growth company until the earlier of (i) the last day of the fiscal year (a) following the fifth anniversary of the completion of this offering, (b) in which we have total annual gross revenue of at least $1.07 billion (as adjusted for inflation pursuant to SEC rules from time to time), or (c) in which we are deemed to be a large accelerated filer, which means the market value of our Class A ordinary shares that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (ii) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. References herein to “emerging growth company” shall have the meaning associated with it in the JOBS Act.

Table of Contents

Additionally, we are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company until the last day of the fiscal year in which (i) the market value of our ordinary shares held by non-affiliates exceeds $250 million as of the end of that year’s second fiscal quarter or (ii) our annual revenues exceeded $100 million during such completed fiscal year and the market value of our ordinary shares held by non-affiliates exceeds $700 million as of the end of that year’s second fiscal quarter.

The following diagram illustrates our simplified ownership structure after giving effect to this offering.

The Offering

In making your decision on whether to invest in our securities, you should take into account not only the backgrounds of the members of our management team, but also the special risks we face as a blank check company and the fact that this offering is not being conducted in compliance with Rule 419 promulgated under the Securities Act. You will not be entitled to protections normally afforded to investors in Rule 419 blank check offerings. You should carefully consider these and the other risks set forth in the section below entitled “Risk Factors” beginning on page 28 of this prospectus.

The founder shares are identical to the Class A ordinary shares sold in this offering, except that:

• only holders of the founder shares have the right to vote on the appointment or removal of directors prior to our initial business combination;

• in respect of any vote or votes to continue the company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction), which requires the approval of at least two-thirds of the votes of all ordinary shares, holders of our founder shares will have ten votes for every founder share and holders of our Class A ordinary shares will have one vote for every Class A ordinary share;

		initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering or (iii) rights to liquidating distributions from the trust account with respect to any founder shares or private placement shares held by them if we fail to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering (although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our business combination within the prescribed time frame). If we submit our initial business combination to our public shareholders for a vote, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association. Tortoise and our sponsor and each member of our management team have agreed to vote any founder shares and private placement shares held by them and any public shares purchased during or after this offering in favor of our initial business combination. As a result, in addition to our initial shareholders’ founder shares and the private placement shares, we would need (i) 10,775,001, or 35.9% (assuming all outstanding shares are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), or (ii) 1,162,501, or 3.9% (assuming only the minimum number of shares representing a quorum are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), of the 30,000,000 public shares sold in this offering to be voted in favor of the business combination in order to have the business combination approved, subject to any higher consent threshold as may be required by Cayman Islands or other applicable law; and
		• the founder shares are entitled to registration rights.
Transfer restrictions on founder shares		Our initial shareholders have agreed not to transfer, assign or sell any founder shares held by them until one year after the date of the consummation of our initial business combination or earlier if, subsequent to our initial business combination, (i) the last sale price of our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination or (ii) we consummate a subsequent liquidation, merger, share exchange or other similar transaction which results in all of our shareholders having the right to exchange their ordinary shares for cash, securities or other property (except as described herein under “Principal Shareholders — Transfers of Founder Shares and Private Placement Shares”). We refer to such transfer restrictions throughout this prospectus as the lock-up.

Table of Contents

Founder shares conversion and anti-dilution rights		We have issued 8,625,000 Class B ordinary shares, par value $0.0001 per share. The Class B ordinary shares will automatically convert into our Class A ordinary shares at the time of our initial business combination on a one-for-one basis, subject to adjustment for share sub-divisions, share dividends, reorganizations, recapitalizations and the like and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in this offering and related to the closing of the initial business combination, the ratio at which Class B ordinary shares shall convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all ordinary shares outstanding upon the completion of this offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the business combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the business combination and the private placement shares).
Voting		Holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of our shareholders, except as required by law. Each ordinary share will have one vote on all such matters. In addition, in respect of any vote or votes to continue the company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction), which requires the approval of at least two-thirds of the votes of all ordinary shares, holders of our founder shares will have ten votes for every founder share and holders of our Class A ordinary shares will have one vote for every Class A ordinary share and, as a result, our initial shareholders will be able to approve any such proposal without the vote of any other shareholder.
Private placement shares		Tortoise has committed, pursuant to a written agreement, to purchase an aggregate of 950,000 private placement shares (or 1,040,000 private placement shares if the underwriters’ over-allotment option is exercised in full), at a price of $10.00 per share (approximately $9,500,000 in the aggregate, or approximately $10,400,000 in the aggregate if the underwriters’ over-allotment option is exercised in full) in a private placement that will close simultaneously with the closing of this offering. A portion of the purchase price of the private placement shares will be added to the proceeds from this offering to be held in the trust account such that at the time of closing $300.0 million (or approximately $345.0 million if the underwriters exercise their over-allotment option in full) will be held in the trust account. If we do not complete our initial business combination within 24 months from the closing of this offering (or 27 months, as applicable), the proceeds from the sale of the private placement shares held in the trust account will be used to fund the redemption of our public shares (subject to the requirements of applicable law) and the private placement shares will be worthless.
Transfer restrictions on private placement shares		The private placement shares will not be transferable, assignable or saleable until the date that is 30 days after the completion of our initial business combination (except as described below under “Principal Shareholders — Transfers of Founder Shares and Private Placement Shares”).

Table of Contents

Proceeds to be held in trust account		The rules of the NYSE provide that at least 90% of the gross proceeds from this offering and the sale of the private placement shares be deposited in a trust account. Of the proceeds we will receive from this offering and the sale of the private placement shares described in this prospectus, $300.0 million, or $10.00 per share (approximately $345.0 million, or $10.00 per share, if the underwriters’ over-allotment option is exercised in full) will be deposited into a U.S.-based trust account at J.P. Morgan Chase Bank, N.A. with Continental Stock Transfer & Trust Company acting as trustee and $9.5 million will be used to pay expenses in connection with the closing of this offering and for working capital following this offering. The proceeds to be placed in the trust account include approximately $10.5 million (or approximately $12.1 million if the underwriters’ over-allotment option is exercised in full) in deferred underwriting discounts and commissions.
		Except with respect to interest earned on the funds held in the trust account that may be released to us to pay our taxes, the proceeds from this offering and the sale of the private placement shares will not be released from the trust account until the earliest of (a) the completion of our initial business combination (including the release of funds to pay any amounts due to any public shareholders who properly exercise their redemption rights in connection therewith), (b) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, and (c) the redemption of our public shares if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law. The proceeds deposited in the trust account could become subject to the claims of our creditors, if any, which could have priority over the claims of our public shareholders.
Anticipated expenses and funding sources		Except as described above with respect to the payment of taxes from interest earned on the funds held in the trust account, unless and until we complete our initial business combination, no proceeds held in the trust account will be available for our use, except the withdrawal of interest to pay our taxes. The proceeds held in the trust account will be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations. We will disclose in each quarterly and annual report filed with the SEC prior to our initial business combination whether the proceeds deposited in the trust account are invested in U.S. government treasury obligations or money market funds or a combination thereof. Based on current interest rates, we expect the trust account to generate approximately $90,000 of interest annually (assuming an interest rate of 0.03% per year); however, we can provide no assurances regarding this amount. Unless and until we complete our initial business combination, we may pay our expenses only from:
		• the net proceeds of this offering and the sale of the private placement shares not held in the trust account, which will be approximately $1,000,000 in working capital after the payment of approximately $2.5 million in expenses relating to this offering; and

Table of Contents

		• any loans or additional investments from our sponsor, members of our management team or their affiliates or other third parties, although they are under no obligation to advance funds or invest in us, and provided that any such loans will not have any claim on the proceeds held in the trust account unless such proceeds are released to us upon completion of our initial business combination.
Conditions to completing our initial business combination		There is no limitation on our ability to raise funds privately or through loans in connection with our initial business combination. The NYSE rules require that our initial business combination must occur with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in the trust account (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time of our signing a definitive agreement in connection with our initial business combination.
		If our board of directors is not able to independently determine the fair market value of the target business or businesses or we are considering an initial business combination with an affiliated entity, we will obtain an opinion from an independent investment banking firm that is a member of FINRA or an independent accounting firm. Our shareholders may not be provided with a copy of such opinion nor will they be able to rely on such opinion.
		We anticipate structuring our initial business combination so that the post-transaction company in which our public shareholders own shares will own or acquire 100% of the equity interests or assets of the target business or businesses. We may, however, structure our initial business combination such that the post-transaction company owns or acquires less than 100% of such interests or assets of the target business in order to meet certain objectives of the target management team or shareholders or for other reasons, including, but not limited to, an Affiliated Joint Acquisition. However, we will only complete such business combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires an interest in the target sufficient for the post-transaction company not to be required to register as an investment company under the Investment Company Act. Even if the post-transaction company owns or acquires 50% or more of the voting securities of the target, our shareholders prior to the business combination may collectively own a minority interest in the post-business combination company, depending on valuations ascribed to the target and us in the business combination transaction. If less than 100% of the equity interests or assets of a target business or businesses are owned or acquired by the post-transaction company, the portion of such business or businesses that is owned or acquired is what will be taken into account for purposes of the NYSE’s 80% of net assets test, provided that in the event that the business combination involves more than one target business, the 80% of net assets test will be based on the aggregate value of all of the transactions, and we will treat the transactions together as our initial business combination for seeking shareholder approval or for purposes of a tender offer, as applicable.

Permitted purchases of public shares by our affiliates		If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our sponsor, directors, officers, advisors or their affiliates may purchase public shares in privately negotiated transactions or in the open market either prior to or following the completion of our initial business combination. However, they have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions. None of the funds held in the trust account will be used to purchase public shares in such transactions. If they engage in such transactions, they will not make any such purchases when they are in possession of any material nonpublic information not disclosed to the seller or if such purchases are prohibited by Regulation M under the Exchange Act. We do not currently anticipate that such purchases, if any, would constitute a tender offer subject to the tender offer rules under the Exchange Act or a going-private transaction subject to the going-private rules under the Exchange Act; however, if the purchasers determine at the time of any such purchases that the purchases are subject to such rules, the purchasers will comply with such rules. Any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent such purchasers are subject to such reporting requirements. See “Proposed Business — Permitted Purchases of our Securities” for a description of how our sponsor, directors, executive officers, advisors or any of their affiliates will select which shareholders to purchase securities from in any private transaction.
		The purpose of any such purchases of shares could be to vote such shares in favor of the business combination and thereby increase the likelihood of obtaining shareholder approval of the business combination or to satisfy a closing condition in an agreement with a target that requires us to have a minimum net worth or a certain amount of cash at the closing of our initial business combination, where it appears that such requirement would otherwise not be met. Any such purchases of our securities may result in the completion of our initial business combination that may not otherwise have been possible. In addition, if such purchases are made, the public “float” of our Class A ordinary shares may be reduced and the number of beneficial holders of our securities may be reduced, which may make it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange.
		There is no limit on the number of public shares that our sponsor, officers, directors or their affiliates may purchase pursuant to the transactions described above.
Redemption rights for public shareholders upon completion of our initial business combination		We will provide our public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of our initial business combination, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the trust account is initially anticipated to be $10.00 per public share. The per share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting discounts and commissions we will pay to the underwriters. Tortoise and our sponsor, officers and directors will not be entitled to redemption rights with respect to any founder shares held by them or any private placement shares or public shares they acquire during or after this offering in connection with the completion of our business combination.

Table of Contents

Limitations on redemptions		Our amended and restated memorandum and articles of association will provide that in no event will the company redeem its public shares in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (so that we are not subject to the SEC’s “penny stock” rules). However, a greater net tangible asset or cash requirement may be contained in the agreement relating to our initial business combination. For example, the proposed business combination may require (i) cash consideration to be paid to the target or its owners, (ii) cash to be transferred to the target for working capital or other general corporate purposes or (iii) the retention of cash to satisfy other conditions in accordance with the terms of the proposed business combination. In the event the aggregate cash consideration we would be required to pay for all of our Class A ordinary shares that are validly submitted for redemption plus any amount required to satisfy cash conditions pursuant to the terms of the proposed business combination exceed the aggregate amount of cash available to us, we will not complete the business combination or redeem any shares, and all of our Class A ordinary shares submitted for redemption will be returned to the holders thereof.
Manner of conducting redemptions		We will provide our public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of our initial business combination either (i) in connection with a general meeting called to approve the business combination or (ii) by means of a tender offer. The decision as to whether we will seek shareholder approval of a proposed business combination or conduct a tender offer will be made by us, solely in our discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require us to seek shareholder approval under applicable law or stock exchange listing requirements. Asset acquisitions and share purchases would not typically require shareholder approval, while direct mergers with our company, including where we do not survive and any transactions where we issue more than 20% of our outstanding ordinary shares or seek to amend our amended and restated memorandum and articles of association would require shareholder approval. We currently intend to conduct redemptions in connection with a shareholder vote unless shareholder approval is not required by applicable law or stock exchange listing requirements and we choose to conduct redemptions pursuant to the tender offer rules of the SEC for business or other legal reasons.
		If we hold a shareholder vote to approve our initial business combination, we will:
		• conduct the redemptions in conjunction with a proxy solicitation pursuant to Regulation 14A of the Exchange Act, which regulates the solicitation of proxies, and not pursuant to the tender offer rules; and • file proxy materials with the SEC.
		If we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association. A quorum for such meeting will consist of the holders present in person or by proxy of the outstanding shares of the company representing a majority of the voting power of all outstanding shares of the

Table of Contents

company entitled to vote at such meeting. Our initial shareholders will count towards this quorum and have agreed to vote their founder shares and any public shares purchased during or after this offering in favor of our initial business combination. For purposes of seeking approval of the requisite majority of our outstanding ordinary shares voted, abstentions and non-votes will have no effect on the approval of our initial business combination once a quorum is obtained. As a result, in addition to our initial shareholders’ founder shares and the private placement shares, we would need (i) 10,775,001, or 35.9% (assuming all outstanding shares are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), or (ii) 1,162,501, or 3.9% (assuming only the minimum number of shares representing a quorum are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), of the 30,000,000 public shares sold in this offering to be voted in favor of an initial business combination in order to have our initial business combination approved, subject to any higher consent threshold as may be required by Cayman Islands or other applicable law. We intend to give approximately 30 days (but not less than 10 days nor more than 60 days) prior written notice of any such meeting, if required, at which a vote shall be taken to approve our initial business combination. These quorum and voting thresholds, and the voting agreements of our initial shareholders, may make it more likely that we will consummate our initial business combination. Each public shareholder may elect to redeem its public shares irrespective of whether they vote for or against the proposed transaction or vote at all.

We may require our public shareholders seeking to exercise their redemption rights, whether they are record holders or hold their shares in “street name,” to either tender their certificates to our transfer agent prior to the date set forth in the proxy solicitation or tender offer materials mailed to such holders, or up to two business days prior to the initially scheduled vote on the proposal to approve the business combination in the event we distribute proxy materials, or to deliver their shares to the transfer agent electronically. We believe that this will allow our transfer agent to efficiently process any redemptions without the need for further communication or action from the redeeming public shareholders, which could delay redemptions and result in additional administrative cost. If the proposed business combination is not approved and we continue to search for a target business, we will promptly return any certificates delivered, or shares tendered electronically, by public shareholders who elected to redeem their shares.

If we conduct redemptions pursuant to the tender offer rules of the SEC, we will, pursuant to our amended and restated memorandum and articles of association:

• conduct the redemptions pursuant to Rule 13e-4 and Regulation 14E of the Exchange Act, which regulate issuer tender offers; and

• file tender offer documents with the SEC prior to completing our initial business combination which contain substantially the same financial and other information about our initial business combination and the redemption rights as is required under Regulation 14A of the Exchange Act, which regulates the solicitation of proxies. Although we are not required to do so, we currently intend to comply with the substantive and procedural requirements of Regulation 14A in connection with any shareholder vote even if we are not able to maintain our NYSE listing or Exchange Act registration.

Table of Contents

Upon the public announcement of our business combination, if we elect to conduct redemptions pursuant to the tender offer rules, we or our sponsor will terminate any plan established in accordance with Rule 10b5-1 to purchase our Class A ordinary shares in the open market, in order to comply with Rule 14e-5 under the Exchange Act.

In the event we conduct redemptions pursuant to the tender offer rules, our offer to redeem will remain open for at least 20 business days, in accordance with Rule 14e-1(a) under the Exchange Act, and we will not be permitted to complete our initial business combination until the expiration of the tender offer period. In addition, the tender offer will be conditioned on public shareholders not tendering more than the number of public shares we are permitted to redeem. If public shareholders tender more shares than we have offered to purchase, we will withdraw the tender offer and not complete the initial business combination.

Limitation on redemption rights of shareholders holding 20% or more of the shares sold in this offering if we hold shareholder vote

Notwithstanding the foregoing redemption rights, if we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our business combination pursuant to the tender offer rules, our amended and restated memorandum and articles of association will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 20% of the shares sold in this offering, without our prior consent. We believe the restriction described above will discourage shareholders from accumulating large blocks of shares, and subsequent attempts by such holders to use their ability to redeem their shares as a means to force us or our management to purchase their shares at a significant premium to the then-current market price or on other undesirable terms. Absent this provision, a public shareholder holding more than an aggregate of 20% of the shares sold in this offering could threaten to exercise its redemption rights against a business combination if such holder’s shares are not purchased by us, our sponsor or our management at a premium to the then-current market price or on other undesirable terms. By limiting our shareholders’ ability to redeem to no more than 20% of the shares sold in this offering, we believe we will limit the ability of a small group of shareholders to unreasonably attempt to block our ability to complete our business combination, particularly in connection with a business combination with a target that requires as a closing condition that we have a minimum net worth or a certain amount of cash. However, we would not be restricting our shareholders’ ability to vote all of their shares (including all shares held by those shareholders that hold more than 20% of the shares sold in this offering) for or against our business combination.

Table of Contents

Redemption rights in connection
with proposed amendments to
our memorandum and articles
of association

Some other blank check companies have a provision in their charter which prohibits the amendment of certain charter provisions. Our amended and restated memorandum and articles of association will provide that any of its provisions (other than amendments relating to the appointment or removal of directors prior to our initial business combination, which require the approval of a majority of at least 90% of our ordinary shares voting at a general meeting) related to pre-business combination activity (including the requirement to deposit proceeds of this offering and the private placement of shares into the trust account and not release such amounts except in specified circumstances, and to provide redemption rights to public shareholders as described herein) may be amended if approved by holders of at least two-thirds of our ordinary shares who attend and vote in a general meeting, and corresponding provisions of the trust agreement governing the release of funds from our trust account may be amended if approved by holders of at least two-thirds of our ordinary shares who attend and vote in a general meeting. Our initial shareholders, who will beneficially own 20% of our ordinary shares upon the closing of this offering (excluding the private placement shares and assuming they do not purchase any shares in this offering), will participate in any vote to amend our amended and restated memorandum and articles of association and/or trust agreement and will have the discretion to vote in any manner they choose. Our sponsor, officers and directors have agreed, pursuant to a written agreement with us, that they will not propose any amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, unless we provide our public shareholders with the opportunity to redeem their Class A ordinary shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares, subject to the limitations described above under “Limitations on redemptions.” For example, our board of directors may propose such an amendment if it determines that additional time is necessary to complete our initial business combination. Pursuant to our amended and restated memorandum and articles of association, such an amendment would need to be approved by the affirmative vote of the holders of at least two-thirds of all then outstanding ordinary shares who attend and vote in a general meeting. In such event, we will conduct a proxy solicitation and distribute proxy materials pursuant to Regulation 14A of the Exchange Act seeking shareholder approval of such proposal, and in connection therewith, provide our public shareholders with the redemption rights described above upon shareholder approval of such amendment. This redemption right shall apply in the event of the approval of any such amendment, whether proposed by our sponsor, any executive officer, director or director nominee, or any other person.

Table of Contents

Release of funds in trust account on closing of our initial business combination		On the completion of our initial business combination, the funds held in the trust account will be used to pay amounts due to any public shareholders who exercise their redemption rights as described above under “Redemption rights for public shareholders upon completion of our initial business combination,” to pay the underwriters their deferred underwriting discounts and commissions, to pay all or a portion of the consideration payable to the target or owners of the target of our initial business combination and to pay other expenses associated with our initial business combination. If our initial business combination is paid for using equity or debt securities, or not all of the funds released from the trust account are used for payment of the consideration in connection with our initial business combination, we may apply the balance of the cash released to us from the trust account for general corporate purposes, including for maintenance or expansion of operations of post-transaction businesses, the payment of principal or interest due on indebtedness incurred in completing our initial business combination, to fund the purchase of other companies or for working capital.
Redemption of public shares and distribution and liquidation if no initial business combination		Our amended and restated memorandum and articles of association provides that we will have only 24 months from the closing of this offering to complete our initial business combination (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering but have not completed the initial business combination within such 24-month period). If we are unable to complete our initial business combination within such 24-month period (or 27-month period, as applicable), we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.
		Tortoise and our sponsor, officers and directors will not be entitled to rights to liquidating distributions from the trust account with respect to any founder shares or private placement shares held by them if we fail to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering. However, if our initial shareholders or management team acquire public shares in or after this offering, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within the allotted 24-month time period (or 27-month time period, as applicable).
		The underwriters have agreed to waive their rights to their deferred underwriting discounts and commissions held in the trust account in the event we do not complete our initial business combination and subsequently liquidate and, in such event, such amounts will be included with the funds held in the trust account that will be available to fund the redemption of our public shares.

Limited payments to insiders		There will be no finder’s fees, reimbursements or cash payments made by the company to our sponsor, officers or directors, or our or their affiliates, for services rendered to us prior to or in connection with the completion of our initial business combination, other than the following payments, none of which will be made from the proceeds of this offering held in the trust account prior to the completion of our initial business combination:
		• repayment of up to an aggregate of $600,000 in loans made to us by our sponsor to cover offering-related and organizational expenses; • reimbursement for office space, utilities, secretarial support and administrative services provided to us by Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, in an amount equal to $10,000 per month; • reimbursement for any out-of-pocket expenses related to identifying, investigating, negotiating and completing an initial business combination; and • repayment of loans which may be made by our sponsor or an affiliate of our sponsor or certain of our officers and directors to finance transaction costs in connection with an intended initial business combination. Up to $1,500,000 of such loans may be convertible into shares of the post business combination entity at a price of $10.00 per share at the option of the lender. The shares would be identical to the private placement shares, including as to exercise price, exercisability and exercise period. Except for the foregoing, the terms of such loans, if any, have not been determined and no written agreements exist with respect to such loans.
		The foregoing payments will be made from the proceeds of the sale of private placement shares that will not be held in the trust account or from the funds available to us from interest income on the trust account balance.
Audit Committee		We will establish and maintain an audit committee, which initially will be composed of a majority of independent directors and, within one year of the date of this offering, will be composed entirely of independent directors. Among its responsibilities, the audit committee will review on a quarterly basis all payments that were made to our sponsor, officers or directors, or our or their affiliates, and monitor compliance with the other terms relating to this offering. If any noncompliance is identified, then the audit committee will be charged with the responsibility to promptly take all action necessary to rectify such noncompliance or otherwise to cause compliance with the terms of this offering. For more information, see the section entitled “Management — Committees of the Board of Directors — Audit Committee.”
Conflicts of Interest		Tortoise manages several investment vehicles. Tortoise and its affiliates may compete with us for acquisition opportunities. If these entities decide to pursue any such opportunity, we may be precluded from pursuing such opportunities. In addition, investment ideas generated within Tortoise may be suitable for both us and for current or future Tortoise Funds and may be directed to such affiliates rather than to us. Neither Tortoise nor members of our management team who are also employed by Tortoise have any obligation to present us with any opportunity for a potential business combination of which they become aware, unless presented to such member solely in his or her capacity as an officer of the company. Tortoise and/or our management, in their capacities as employees of Tortoise or in their other endeavors, may be required to present potential business combinations to the related entities described above, current or future affiliates of Tortoise or third parties, before they present such opportunities to us.

Table of Contents

		Each of our officers and directors presently has, and any of them in the future may have additional, fiduciary or contractual obligations to other entities pursuant to which such officer or director is or will be required to present a business combination opportunity. Accordingly, if any of our officers or directors becomes aware of a business combination opportunity which is suitable for an entity to which he or she has then-current fiduciary or contractual obligations, he or she will honor his or her fiduciary or contractual obligations to present such opportunity to such other entity. We do not believe, however, that the fiduciary duties or contractual obligations of our officers or directors will materially affect our ability to complete our business combination.
		Our sponsor, members of our management team or their affiliates may sponsor other special purpose acquisition companies similar to ours during the period in which we are seeking an initial business combination and our officers and directors may become an officer or director of any other special purpose acquisition company with a class of securities registered under the Exchange Act, even before we have entered into a letter of intent, agreement in principle or definitive agreement regarding our initial business combination. Any such companies may present additional conflicts of interest in pursuing an acquisition target, particularly in the event there is an overlap among the management teams. For more information, see “Management — Conflicts of Interest.”
		Notwithstanding the foregoing, we may pursue an Affiliated Joint Acquisition opportunity with any affiliates of Tortoise or the Tortoise Funds. Such entities may co-invest with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the acquisition by issuing to such entity a class of equity or equity-linked securities.
Indemnity		Our sponsor has agreed that it will be liable to us if and to the extent any claims by a third party (other than our independent public accountants) for services rendered or products sold to us, or by a prospective target business with which we have entered into a letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the trust account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay our taxes.
		This liability will not apply with respect to any claims by a third party or prospective target business who executed a waiver of any and all rights to seek access to the trust account and except as to any claims under our indemnity of the underwriters of this offering against certain liabilities, including liabilities under the Securities Act. Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, then our sponsor will not be responsible to the extent of any liability for such third-party claims. We have not independently verified whether our sponsor has sufficient funds to satisfy its indemnity obligations and believe that our sponsor’s only assets are securities of our company. We have not asked our sponsor to reserve for such indemnification obligations. None of our officers will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Risks

We are a newly incorporated company that has conducted no operations and has generated no revenues. Until we complete our initial business combination, we will have no operations and will generate no operating revenues. In making your decision whether to invest in our securities, you should take into account not only the background of our management team, but also the special risks we face as a blank check company. This offering is not being conducted in compliance with Rule 419 promulgated under the Securities Act. Accordingly, you will not be entitled to protections normally afforded to investors in Rule 419 blank check offerings. For additional information concerning how Rule 419 blank check offerings differ from this offering, please see “Proposed Business — Comparison of This Offering to Those of Blank Check Companies Subject to Rule 419.” You should carefully consider these and the other risks set forth in the section entitled “Risk Factors” beginning on page 28 of this prospectus. Such risks include, but are not limited to:

• We are a newly incorporated company with no operating history and no revenues, and you have no basis on which to evaluate our ability to achieve our business objective.

• Our public shareholders may not be afforded an opportunity to vote on our proposed business combination, which means we may complete our initial business combination even though a majority of our public shareholders do not support such a combination.

• Your only opportunity to affect the investment decision regarding a potential business combination may be limited to the exercise of your right to redeem your shares from us for cash.

• Our search for a business combination, and any target business with which we ultimately consummate a business combination, may be materially adversely affected by the ongoing coronavirus (COVID-19) pandemic and the status of debt and equity markets.

• We may not be able to complete our initial business combination within the 24 months (or 27 months, as applicable) after the closing of this offering, in which case we would cease all operations except for the purpose of winding up and we would redeem our public shares and liquidate, in which case our public shareholders may receive only their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

• Because we are not limited to a particular industry, sector or any specific target businesses with which to pursue our initial business combination, you will be unable to ascertain the merits or risks of any particular target business’s operations.

• Although we have identified general criteria and guidelines that we believe are important in evaluating prospective target businesses, we may enter into our initial business combination with a target that does not meet such criteria and guidelines, and as a result, the target business with which we enter into our initial business combination may not have attributes entirely consistent with our general criteria and guidelines.

• We may seek business combination opportunities with a financially unstable business or an entity lacking an established record of revenue or earnings, which could subject us to volatile revenues, cash flows or earnings or difficulty in retaining key personnel.

• Our initial business combination may be structured in a manner that is not tax-efficient for shareholders, and our shareholders may be subject to additional income, withholding or other taxes with respect to their ownership of us after our initial business combination. In addition, as a result of our business combination, our tax obligations may be more complex, burdensome and uncertain.

• We may not hold an annual general meeting until after the consummation of our initial business combination, which could delay the opportunity for our shareholders to appoint directors.

• Past performance by our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, the Tortoise Funds, Lightfoot Capital, and by companies affiliated with celebrities or public figures, and any related investment may not be indicative of future performance of an investment in us.

Table of Contents

• We may engage in a business combination with one or more target businesses that have relationships with entities that may be affiliated with our sponsor, officers, directors or Tortoise which may raise potential conflicts of interest.

• Since our sponsor, officers and directors will lose their entire investment in us if our business combination is not completed (other than with respect to public shares they may acquire during or after this offering), a conflict of interest may arise in determining whether a particular business combination target is appropriate for our initial business combination.

• Our management may not be able to maintain control of a target business after our initial business combination. We cannot provide assurance that, upon loss of control of a target business, new management will possess the skills, qualifications or abilities necessary to profitably operate such business.

• Our initial shareholders will control the appointment of our board of directors until consummation of our initial business combination and will hold a substantial interest in us. As a result, they will appoint and remove all of our directors prior to our initial business combination and may exert a substantial influence on actions requiring a shareholder vote, potentially in a manner that you do not support.

• An investment in our Class A ordinary shares, and certain subsequent transactions with respect to our Class A ordinary shares, may result in uncertain or adverse U.S. federal income tax consequences, including uncertainty with respect to the applicable holding period of our Class A ordinary shares.

• We may be treated as a passive foreign investment company, which could result in adverse U.S. federal income tax consequences to U.S. investors.

• The other risks and uncertainties discussed in “Risk Factors” and elsewhere in this prospectus.

Summary Financial Data

The following table summarizes the relevant financial data for our business and should be read with our financial statements, which are included in this prospectus. We have not had any significant operations to date, so only balance sheet data is presented.

	February 9, 2021
	Actual			As Adjusted
Balance Sheet Data:
Working capital (deficiency)	$	(104,621	)	$	290,515,379
Total assets	$	135,379		$	301,015,379
Total liabilities	$	120,000		$	10,500,000
Value of Class A ordinary shares subject to possible redemption	$	—		$	285,515,370
Shareholder’s equity	$	15,379		$	5,000,009

The “as adjusted” information gives effect to the sale of the ordinary shares in this offering, the sale of the private placement shares, repayment of up to an aggregate of $600,000 in loans made to us by our sponsor and the payment of the estimated expenses of this offering and assumes no exercise of the underwriters’ over-allotment option. The “as adjusted” total assets amount includes the $300,000,000 held in the trust account for the benefit of our public shareholders, which amount, less deferred underwriting commissions, will be available to us only upon the completion of our initial business combination within 24 months from the closing of this offering (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering). The “as adjusted” working capital and “as adjusted” total assets include $10,500,000 being held in the trust account representing deferred underwriting commission. The underwriters will not be entitled to any interest accrued on the deferred underwriting discounts and commission.

If no business combination is completed within 24 months from the closing of this offering (or 27 months, as applicable), the proceeds then on deposit in the trust account including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), will be used to fund the redemption of our public shares. Tortoise and our sponsor, officers and directors will not be entitled to rights to liquidating distributions from the trust account with respect to any founder shares or private placement shares held by them if we fail to complete our initial business combination within such 24 month time period (or 27 month time period, as applicable).

Risk Factors

An investment in our securities involves a high degree of risk. You should consider carefully all of the risks described below, together with the other information contained in this prospectus, before making a decision to invest in our Class A ordinary shares. If any of the following events occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment.

Risks Relating to our Search for, Consummation of or Inability to Consummate, a Business Combination and Post-Business Combination Risks

We are a newly incorporated company with no operating history and no revenues, and you have no basis on which to evaluate our ability to achieve our business objective.

We are a newly incorporated company established in the Cayman Islands with no operating results, and we will not commence operations until obtaining funding through this offering. Because we lack an operating history, you have no basis upon which to evaluate our ability to achieve our business objective of completing our initial business combination with one or more target businesses. We have no plans, arrangements or understandings with any prospective target business concerning a business combination and may be unable to complete our business combination. If we fail to complete our business combination, we will never generate any operating revenues.

Our public shareholders may not be afforded an opportunity to vote on our proposed business combination, which means we may complete our initial business combination even though a majority of our public shareholders do not support such a combination.

We may choose not to hold a shareholder vote to approve our initial business combination if the business combination would not require shareholder approval under applicable law or stock exchange listing requirements. Except as required by applicable law or stock exchange requirement, the decision as to whether we will seek shareholder approval of a proposed business combination or will allow shareholders to sell their shares to us in a tender offer will be made by us, solely in our discretion, and will be based on a variety of factors, such as the timing of the transaction and whether the terms of the transaction would otherwise require us to seek shareholder approval. Accordingly, we may complete our initial business combination even if holders of a majority of our public shares do not approve of the business combination we complete. Please see the section entitled “Proposed Business — Shareholders May Not Have the Ability to Approve Our Initial Business Combination” for additional information.

Your only opportunity to affect the investment decision regarding a potential business combination may be limited to the exercise of your right to redeem your shares from us for cash.

At the time of your investment in us, you will not be provided with an opportunity to evaluate the specific merits or risks of our initial business combination. Since our board of directors may complete a business combination without seeking shareholder approval, public shareholders may not have the right or opportunity to vote on the business combination, unless we seek such shareholder vote. Accordingly, if we do not seek shareholder approval, your only opportunity to affect the investment decision regarding a potential business combination may be limited to exercising your redemption rights within the period of time (which will be at least 20 business days) set forth in our tender offer documents mailed to our public shareholders in which we describe our initial business combination.

If we seek shareholder approval of our initial business combination, our initial shareholders and management team have agreed to vote in favor of such initial business combination, regardless of how our public shareholders vote.

Our initial shareholders will own 20% of our outstanding ordinary shares immediately following the completion of this offering (excluding the private placement shares and assuming they do not purchase any shares in this offering). Our initial shareholders and management team also may from time to time purchase Class A ordinary shares prior to our initial business combination. Our amended and restated memorandum and articles of association will provide that, if we seek shareholder approval of an initial business combination, such initial business combination will be approved only if we obtain the approval of an ordinary resolution under Cayman

Table of Contents

Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association, including the founder shares. As a result, in addition to our initial shareholders’ founder shares and the private placement shares, we would need (i) 10,775,001, or 35.9% (assuming all outstanding shares are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), or (ii) 1,162,501, or 3.9% (assuming only the minimum number of shares representing a quorum are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), of the 30,000,000 public shares sold in this offering to be voted in favor of an initial business combination in order to have our initial business combination approved, subject to any higher consent threshold as may be required by Cayman Islands or other applicable law. Accordingly, if we seek shareholder approval of our initial business combination, the agreement by our initial shareholders and management team to vote in favor of our initial business combination will increase the likelihood that we will receive the requisite shareholder approval for such initial business combination.

The ability of our public shareholders to redeem their shares for cash may make our financial condition unattractive to potential business combination targets, which may make it difficult for us to enter into a business combination with a target.

We may seek to enter into a business combination transaction agreement with a prospective target that requires as a closing condition that we have a minimum net worth or a certain amount of cash. If too many public shareholders exercise their redemption rights, we would not be able to meet such closing condition and, as a result, would not be able to proceed with the business combination. Furthermore, in no event will we redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (so that we are not subject to the SEC’s “penny stock” rules). Consequently, if accepting all properly submitted redemption requests would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions or such greater amount necessary to satisfy a closing condition as described above, we would not proceed with such redemption and the related business combination and may instead search for an alternate business combination. Prospective targets will be aware of these risks and, thus, may be reluctant to enter into a business combination transaction with us.

The ability of our public shareholders to exercise redemption rights with respect to a large number of our shares may not allow us to complete the most desirable business combination or optimize our capital structure.

At the time we enter into an agreement for our initial business combination, we will not know how many shareholders may exercise their redemption rights, and therefore will need to structure the transaction based on our expectations as to the number of shares that will be submitted for redemption. If our business combination agreement requires us to use a portion of the cash in the trust account to pay the purchase price, or requires us to have a minimum amount of cash at closing, we will need to reserve a portion of the cash in the trust account to meet such requirements, or arrange for third-party financing. In addition, if a larger number of shares are submitted for redemption than we initially expected, we may need to restructure the transaction to reserve a greater portion of the cash in the trust account or arrange for third-party financing. Raising additional third-party financing may involve dilutive equity issuances or the incurrence of indebtedness at higher than desirable levels. The above considerations may limit our ability to complete the most desirable business combination available to us or optimize our capital structure. The amount of the deferred underwriting discounts and commissions payable to the underwriters will not be adjusted for any shares that are redeemed in connection with a business combination. The per-share amount we will distribute to shareholders who properly exercise their redemption rights will not be reduced by the deferred underwriting discounts and commissions and after such redemptions, the amount held in trust will continue to reflect our obligation to pay the entire deferred underwriting discounts and commissions.

The ability of our public shareholders to exercise redemption rights with respect to a large number of our shares could increase the probability that our initial business combination would be unsuccessful and that you would have to wait for liquidation in order to redeem your shares.

If our business combination agreement requires us to use a portion of the cash in the trust account to pay the purchase price, or requires us to have a minimum amount of cash at closing, the probability that our initial business combination would be unsuccessful is increased. If our initial business combination is unsuccessful, you would not receive your pro rata portion of the funds in the trust account until we liquidate the trust account. If you are in need

Table of Contents

of immediate liquidity, you could attempt to sell your shares in the open market; however, at such time our shares may trade at a discount to the pro rata amount per share in the trust account. In either situation, you may suffer a material loss on your investment or lose the benefit of funds expected in connection with our redemption until we liquidate or you are able to sell your shares in the open market.

The requirement that we complete our initial business combination within 24 months (or 27 months, as applicable) after the closing of this offering may give potential target businesses leverage over us in negotiating a business combination and may limit the time we have to conduct due diligence on potential business combination targets as we approach our initial business combination deadline, which could undermine our ability to complete our business combination on terms that would produce value for our shareholders.

Any potential target business with which we enter into negotiations concerning a business combination will be aware that we must complete our initial business combination within 24 months from the closing of this offering (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering). Consequently, such target business may obtain leverage over us in negotiating a business combination, knowing that if we do not complete our initial business combination with that particular target business, we may be unable to complete our initial business combination with any target business. This risk will increase as we get closer to the timeframe described above. In addition, we may have limited time to conduct due diligence and may enter into our initial business combination on terms that we would have rejected upon a more comprehensive investigation.

Our search for a business combination, and any target business with which we ultimately consummate a business combination, may be materially adversely affected by the ongoing coronavirus (COVID-19) pandemic and the status of debt and equity markets.

In December 2019, a novel strain of coronavirus was reported to have surfaced in Wuhan, China, which has and is continuing to spread throughout the world, including the United States. On January 30, 2020, the World Health Organization declared the outbreak of the coronavirus disease (COVID-19) a “Public Health Emergency of International Concern.” On January 31, 2020, U.S. Health and Human Services Secretary Alex M. Azar II declared a public health emergency for the United States to aid the U.S. healthcare community in responding to COVID-19, and on March 11, 2020, the World Health Organization characterized the outbreak as a “pandemic.” The pandemic, together with resulting voluntary and U.S. federal and state and non-U.S. governmental actions, including, without limitation, mandatory business closures, public gathering limitations, restrictions on travel and quarantines, has meaningfully disrupted the global economy and markets. Although the long-term economic fallout of COVID-19 is difficult to predict, it has and is expected to continue to have ongoing material adverse effects across many, if not all, aspects of the regional, national and global economy. The COVID-19 outbreak has resulted, and a significant outbreak of other infectious diseases could result, in a widespread health crisis that has adversely affected, in the case of COVID-19, and could adversely affect, in the case of future outbreaks of infectious diseases, the economies and financial markets worldwide, and the business of any potential target business with which we consummate a business combination could be materially and adversely affected. Furthermore, we may be unable to complete a business combination if continued concerns relating to COVID-19 continues to restrict travel, limit the ability to have meetings with potential investors or the target company’s personnel, vendors and services providers are unavailable to negotiate and consummate a transaction in a timely manner. The extent to which COVID-19 impacts our search for a business combination will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19, any potential resurgences of COVID-19 and the actions to contain COVID-19 or treat its impact, among others. If the disruptions posed by COVID-19 or other matters of global concern continue for an extensive period of time, our ability to consummate a business combination, or the operations of a target business with which we ultimately consummate a business combination, may be materially adversely affected.

In addition, our ability to consummate a transaction may be dependent on the ability to raise equity and debt financing which may be impacted by COVID-19 and other events, including as a result of increased market volatility, decreased market liquidity and third-party financing being unavailable on terms acceptable to us or at all. Finally, the outbreak of COVID-19 may also have the effect of heightening many of the other risks described in this “Risk Factors” section.

Table of Contents

We may not be able to complete our initial business combination within the 24 months (or 27 months, as applicable) after the closing of this offering, in which case we would cease all operations except for the purpose of winding up and we would redeem our public shares and liquidate, in which case our public shareholders may receive only their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

We may not be able to find a suitable target business and complete our initial business combination within 24 months (or 27 months, as applicable) after the closing of this offering. Our ability to complete our initial business combination may be negatively impacted by general market conditions, volatility in the capital and debt markets and the other risks described herein. If we have not completed our initial business combination within such time period, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In such case, our public shareholders may only receive $10.00 per share, and our private placement shares will be worthless. In certain circumstances, our public shareholders may receive less than $10.00 per share on the redemption of their shares. See “— If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per-share redemption amount received by shareholders may be less than $10.00 per share” and other risk factors described in this “Risk Factors” section.

If we seek shareholder approval of our initial business combination, our initial shareholders, sponsor, directors, officers, advisors and their affiliates may elect to purchase shares from public shareholders, which may influence a vote on a proposed business combination and reduce the public “float” of our Class A ordinary shares.

In the event that our sponsor, directors, officers, advisors or their affiliates purchase shares in privately negotiated transactions from public shareholders who have already elected to exercise their redemption rights, such selling shareholders would be required to revoke their prior elections to redeem their shares. The purpose of any such purchases of shares could be to vote such shares in favor of the business combination and thereby increase the likelihood of obtaining shareholder approval of the business combination or to satisfy a closing condition in an agreement with a target that requires us to have a minimum net worth or a certain amount of cash at the closing of our business combination, where it appears that such requirement would otherwise not be met. Any such purchases of our securities may result in the completion of our business combination that may not otherwise have been possible. Any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent the purchasers are subject to such reporting requirements. See “Proposed Business — Permitted Purchases of our Securities” for a description of how our sponsor, directors, officers, advisors or any of their affiliates will select which shareholders to purchase securities from in any private transaction.

In addition, if such purchases are made, the public “float” of our Class A ordinary shares and the number of beneficial holders of our securities may be reduced, possibly making it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange.

Table of Contents

If a shareholder fails to receive notice of our offer to redeem our public shares in connection with our business combination, or fails to comply with the procedures for tendering its shares, such shares may not be redeemed.

We will comply with the proxy rules or tender offer rules, as applicable, when conducting redemptions in connection with our business combination. Despite our compliance with these rules, if a shareholder fails to receive our proxy solicitation or tender offer materials, as applicable, such shareholder may not become aware of the opportunity to redeem its shares. In addition, the proxy solicitation or tender offer materials, as applicable, that we will furnish to holders of our public shares in connection with our initial business combination will describe the various procedures that must be complied with in order to validly redeem or tender public shares. For example, we may require our public shareholders seeking to exercise their redemption rights, whether they are record holders or hold their shares in “street name,” to either tender their certificates to our transfer agent prior to the date set forth in the proxy solicitation or tender offer materials mailed to such holders, or up to two business days prior to the initially scheduled vote on the proposal to approve the business combination in the event we distribute proxy materials, or to deliver their shares to the transfer agent electronically. In the event that a shareholder fails to comply with these or any other procedures, its shares may not be redeemed. See “Proposed Business — Business Strategy — Tendering Share Certificates in Connection with a Tender Offer or Redemption Rights.”

If we seek shareholder approval of our initial business combination and we do not conduct redemptions pursuant to the tender offer rules, and if you or a “group” of shareholders are deemed to hold in excess of 20% of our Class A ordinary shares, you will lose the ability to redeem all such shares in excess of 20% of our Class A ordinary shares.

If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our amended and restated memorandum and articles of association will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 20% of the shares sold in this offering without our prior consent, which we refer to as the “Excess Shares.” However, we would not be restricting our shareholders’ ability to vote all of their shares (including Excess Shares) for or against our business combination. Your inability to redeem the Excess Shares will reduce your influence over our ability to complete our business combination and you could suffer a material loss on your investment in us if you sell Excess Shares in open market transactions. Additionally, you will not receive redemption distributions with respect to the Excess Shares if we complete our business combination. And as a result, you will continue to hold that number of shares exceeding 20% and, in order to dispose of such shares, would be required to sell your shares in open market transactions, potentially at a loss.

Because of our limited resources and the significant competition for business combination opportunities, it may be more difficult for us to complete our initial business combination. If we are unable to complete our initial business combination, our public shareholders may receive only their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

We expect to encounter intense competition from other entities having a business objective similar to ours, including private investors (which may be individuals or investment partnerships), other blank check companies and other entities, domestic and international, competing for the types of businesses we intend to acquire. Many of these individuals and entities are well-established and have extensive experience in identifying and effecting, directly or indirectly, acquisitions of companies operating in or providing services to various industries. Many of these competitors possess greater technical, human and other resources or more local industry knowledge than we do and our financial resources will be relatively limited when contrasted with those of many of these competitors. While we believe there are numerous target businesses we could potentially acquire with the net proceeds of this offering and the sale of the private placement shares, our ability to compete with respect to the acquisition of certain target businesses that are sizable will be limited by our available financial resources. This inherent competitive limitation gives others an advantage in pursuing the acquisition of certain target businesses. Furthermore, we are obligated to offer holders of our public shares the right to redeem their shares for cash at the time of our initial business combination, in conjunction with a shareholder vote or via a tender offer. Target businesses will be aware that this may reduce the resources available to us for our initial business combination. Any of these obligations may place us

Table of Contents

at a competitive disadvantage in successfully negotiating a business combination. If we are unable to complete our initial business combination, our public shareholders may receive only their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless. In certain circumstances, our public shareholders may receive less than $10.00 per share upon our liquidation. See “— If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per-share redemption amount received by shareholders may be less than $10.00 per share” and other risk factors described in this “Risk Factors” section.

If the net proceeds of this offering and the sale of the private placement shares not being held in the trust account are insufficient to allow us to operate for at least the next 24 months (or 27 months, as applicable), we may be unable to complete our initial business combination, in which case our public shareholders may only receive $10.00 per share, or less than such amount in certain circumstances, and our private placement shares will be worthless.

The funds available to us outside of the trust account may not be sufficient to allow us to operate for at least the next 24 months (or 27 months, as applicable), assuming that our initial business combination is not completed during that time. We believe that, upon the closing of this offering, the funds available to us outside of the trust account, after taking into account funds that we expect would be made available to us from loans from our sponsor, members of our management team or any of their affiliates, will be sufficient to allow us to operate for at least the next 24 months (or 27 months, as applicable); however, we cannot assure you that our estimate is accurate. Of the funds available to us, we could use a portion of the funds available to us to pay fees to consultants to assist us with our search for a target business. We could also use a portion of the funds as a down payment or to fund a “no-shop” provision (a provision in letters of intent or merger agreements designed to keep target businesses from “shopping” around for transactions with other companies on terms more favorable to such target businesses) with respect to a particular proposed business combination, although we do not have any current intention to do so. If we entered into a letter of intent or merger agreement where we paid for the right to receive exclusivity from a target business and were subsequently required to forfeit such funds (whether as a result of our breach or otherwise), we might not have sufficient funds to continue searching for, or conduct due diligence with respect to, a target business. If we are unable to complete our initial business combination, our public shareholders may receive only approximately $10.00 per share on the liquidation of our trust account and our private placement shares will be worthless. In certain circumstances, our public shareholders may receive less than $10.00 per share upon our liquidation. See “— If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per-share redemption amount received by shareholders may be less than $10.00 per share” and other risk factors described in this “Risk Factors” section.

If the net proceeds of this offering and the sale of the private placement shares not being held in the trust account are insufficient to allow us to operate for at least the next 24 months (or 27 months, as applicable), it could limit the amount available to fund our search for a target business or businesses and complete our initial business combination and we will depend on loans from our sponsor or management team to fund our search for a business combination, to pay our taxes and to complete our initial business combination. If we are unable to obtain these loans, we may be unable to complete our initial business combination.

Of the net proceeds of this offering and the sale of the private placement shares, only approximately $1,000,000 will be available to us initially outside the trust account to fund our working capital requirements. In the event that our offering expenses exceed our estimate of $2,500,000, we may fund such excess with funds not to be held in the trust account. In such case, the amount of funds we intend to be held outside the trust account would decrease by a corresponding amount. Conversely, in the event that the offering expenses are less than our estimate of $2,500,000, the amount of funds we intend to be held outside the trust account would increase by a corresponding amount. The amount held in the trust account will not be impacted as a result of such increase or decrease. If we are required to seek additional capital, we would need to borrow funds from our sponsor, management team or other third parties to operate or we may be forced to liquidate. None of our sponsor, members of our management team nor any of their affiliates is under any obligation to advance funds to us in such circumstances. Any such advances would be repaid only from funds held outside the trust account or from funds released to us upon completion of our initial business combination. Up to $1,500,000 of such loans may be convertible into shares of the post-business combination entity at a price of $10.00 per share at the option of the lender. The shares would be identical to the private placement shares. Prior to the completion of our initial business combination, we do not expect to seek loans

Table of Contents

from parties other than our sponsor or an affiliate of our sponsor as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our trust account. If we are unable to complete our initial business combination because we do not have sufficient funds available to us, we will be forced to cease operations and liquidate the trust account. Consequently, our public shareholders may only receive an estimated $10.00 per share, or possibly less, on our redemption of our public shares, and our private placement shares will be worthless. See “— If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per-share redemption amount received by shareholders may be less than $10.00 per share” and other risk factors described in this “Risk Factors” section.

Subsequent to our completion of our initial business combination, we may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, results of operations and our share price, which could cause you to lose some or all of your investment.

Even if we conduct extensive due diligence on a target business with which we combine, we cannot assure you that this diligence will surface all material issues in relation to a particular target business, that it would be possible to uncover all material issues through a customary amount of due diligence, or that factors outside of the target business and outside of our control will not later arise. As a result of these factors, we may be forced to later write-down or write-off assets, restructure our operations, or incur impairment or other charges that could result in our reporting losses. Even if our due diligence successfully identifies certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with our preliminary risk analysis. Even though these charges may be non-cash items and not have an immediate impact on our liquidity, the fact that we report charges of this nature could contribute to negative market perceptions about us or our securities. In addition, charges of this nature may cause us to violate net worth or other covenants to which we may be subject as a result of assuming pre-existing debt held by a target business or by virtue of our obtaining post-combination debt financing. Accordingly, any shareholders who choose to remain shareholders following the business combination could suffer a reduction in the value of their securities. Such shareholders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by our officers or directors of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the proxy solicitation or tender offer materials, as applicable, relating to the business combination contained an actionable material misstatement or material omission.

Changes in laws or regulations, or a failure to comply with any laws and regulations, may adversely affect our business, including our ability to negotiate and complete our initial business combination, and results of operations.

We are subject to laws and regulations enacted by national, regional and local governments. In particular, we will be required to comply with certain SEC and other legal requirements. Compliance with, and monitoring of, applicable laws and regulations may be difficult, time consuming and costly. Those laws and regulations and their interpretation and application may also change from time to time and those changes could have a material adverse effect on our business, investments and results of operations. In addition, a failure to comply with applicable laws or regulations, as interpreted and applied, could have a material adverse effect on our business, including our ability to negotiate and complete our initial business combination, and results of operations.

Because we are not limited to a particular industry, sector or any specific target businesses with which to pursue our initial business combination, you will be unable to ascertain the merits or risks of any particular target business’s operations.

Although we expect to focus our search for a target business in the broad energy transition or sustainability arena targeting industries that require innovative solutions to decarbonize in order to meet critical emission reduction objectives, we may complete a business combination with an operating company in any industry or sector. However, we will not, under our amended and restated memorandum and articles of association, be permitted to effectuate our business combination with another blank check company or similar company with nominal operations. Because we have not yet selected or approached any specific target business with respect to a business combination, there is no basis to evaluate the possible merits or risks of any particular target business’s operations, results of operations, cash flows, liquidity, financial condition or prospects. To the extent we complete our business combination, we may be affected by numerous risks inherent in the business operations with which we combine. For example, if we combine

Table of Contents

with a financially unstable business or an entity lacking an established record of revenues or earnings, we may be affected by the risks inherent in the business and operations of a financially unstable or a development stage entity. Although our officers and directors will endeavor to evaluate the risks inherent in a particular target business, we cannot assure you that we will properly ascertain or assess all of the significant risk factors or that we will have adequate time to complete due diligence. Furthermore, some of these risks may be outside of our control and leave us with no ability to control or reduce the chances that those risks will adversely impact a target business. We also cannot assure you that an investment in our Class A ordinary shares will ultimately prove to be more favorable to investors than a direct investment, if such opportunity were available, in a business combination target. Accordingly, any shareholders who choose to remain shareholders following the business combination could suffer a reduction in the value of their securities. Such shareholders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by our officers or directors of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the proxy solicitation or tender offer materials (as applicable) relating to the business combination contained an actionable material misstatement or material omission.

Although we have identified general criteria and guidelines that we believe are important in evaluating prospective target businesses, we may enter into our initial business combination with a target that does not meet such criteria and guidelines, and as a result, the target business with which we enter into our initial business combination may not have attributes entirely consistent with our general criteria and guidelines.

Although we have identified general criteria and guidelines for evaluating prospective target businesses, it is possible that a target business with which we enter into our initial business combination will not have all of these positive attributes. If we complete our initial business combination with a target that does not meet some or all of these guidelines, such combination may not be as successful as a combination with a business that does meet all of our general criteria and guidelines. In addition, if we announce a prospective business combination with a target that does not meet our general criteria and guidelines, a greater number of shareholders may exercise their redemption rights, which may make it difficult for us to meet any closing condition with a target business that requires us to have a minimum net worth or a certain amount of cash. In addition, if shareholder approval of the transaction is required by law, or we decide to obtain shareholder approval for business or other legal reasons, it may be more difficult for us to attain shareholder approval of our initial business combination if the target business does not meet our general criteria and guidelines. If we are unable to complete our initial business combination, our public shareholders may only receive their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

We may seek business combination opportunities with an early stage company, a financially unstable business or an entity lacking an established record of revenue or earnings, which could subject us to volatile revenues, cash flows or earnings or difficulty in retaining key personnel.

To the extent we complete our initial business combination with an early stage company, a financially unstable business or an entity lacking an established record of revenues, cash flows or earnings, we may be affected by numerous risks inherent in the operations of the business with which we combine. These risks include investing in a business without a proven business model and with limited historical financial data, volatile revenues, cash flows or earnings and difficulties in obtaining and retaining key personnel. Although our officers and directors will endeavor to evaluate the risks inherent in a particular target business, we may not be able to properly ascertain or assess all of the significant risk factors and we may not have adequate time to complete due diligence. Furthermore, some of these risks may be outside of our control and leave us with no ability to control or reduce the chances that those risks will adversely impact a target business.

We are not required to obtain an opinion from an independent investment banking firm or from an independent accounting firm, and consequently, you may have no assurance from an independent source that the price we are paying for the business is fair to our company from a financial point of view.

Unless we complete our business combination with an affiliated entity, we are not required to obtain an opinion from an independent investment banking firm that is a member of FINRA or from an independent accounting firm that the price we are paying is fair to our company from a financial point of view. If no opinion is obtained, our shareholders will be relying on the judgment of our board of directors, who will determine fair market

Table of Contents

value based on standards generally accepted by the financial community. Such standards used will be disclosed in our proxy solicitation or tender offer materials, as applicable, related to our initial business combination. If our board of directors is not able to independently determine the fair market value of our initial business combination, we will obtain an opinion from an independent investment banking firm. However, our shareholders may not be provided with a copy of such opinion, nor will they be able to rely on such opinion.

We may engage one or more of the underwriters or their respective affiliates to provide additional services to us after this offering, which may include acting as financial advisor in connection with an initial business combination or as placement agent in connection with a related financing transaction. The underwriters are entitled to receive deferred commissions that will be released from the trust account only upon completion of an initial business combination. These financial incentives may cause them to have potential conflicts of interest in rendering any such additional services to us after this offering, including, for example, in connection with the sourcing and consummation of an initial business combination.

We may engage one or more of underwriters or their respective affiliates to provide additional services to us after this offering, including, for example, identifying potential targets, providing financial advisory services, acting as a placement agent in a private offering or arranging debt financing. We may pay such underwriter or its affiliate fair and reasonable fees or other compensation that would be determined at that time in an arm’s length negotiation; provided that no agreement will be entered into with any of the underwriters or their respective affiliates and no fees or other compensation for such services will be paid to any of the underwriters or their respective affiliates prior to the date that is 60 days from the date of this prospectus, unless such payment would not be deemed underwriters’ compensation in connection with this offering. The underwriters are also entitled to receive deferred commissions that are conditioned on the completion of an initial business combination. The underwriters’ or their respective affiliates’ financial interests tied to the consummation of a business combination transaction may give rise to potential conflicts of interest in providing any such additional services to us, including potential conflicts of interest in connection with the sourcing and consummation of an initial business combination.

Our initial business combination and our structure thereafter may not be tax-efficient to shareholders. As a result of our business combination, our tax obligations may be more complex, burdensome and uncertain.

Although we will attempt to structure our initial business combination in a tax-efficient manner, tax structuring considerations are complex, the relevant facts and law are uncertain and may change, and we may prioritize commercial and other considerations over tax considerations. For example, in connection with our initial business combination and subject to requisite shareholder approval under the Companies Act, we may structure our business combination in a manner that requires shareholders to recognize gain or income for tax purposes. We do not intend to make any cash distributions to shareholders to pay taxes in connection with our business combination or thereafter. Accordingly, a shareholder may need to satisfy any liability resulting from our initial business combination with cash from its own funds or by selling all or a portion of such holder’s shares .

Furthermore, we will likely effect a business combination with a target company that has business operations outside of the Cayman Islands and, possibly, business operations in multiple jurisdictions, and we may reincorporate in a different jurisdiction in connection therewith (including, but not limited to, the jurisdiction in which the target company or business is located). If we effect such a business combination, we could be subject to significant income, withholding and other tax obligations in a number of jurisdictions with respect to income, operations and subsidiaries related to those jurisdictions. Due to the complexity of tax obligations and filings in many jurisdictions, we may have a heightened risk related to audits or examinations by taxing authorities. This additional complexity and risk could have an adverse effect on our after-tax profitability and financial condition. In addition, shareholders may also be subject to additional income, withholding or other taxes with respect to their ownership of us after our initial business combination.

We may issue notes or other debt securities, or otherwise incur substantial debt, to complete a business combination, which may adversely affect our leverage and financial condition and thus negatively impact the value of our shareholders’ investment in us.

Although we have no commitments as of the date of this prospectus to issue any notes or other debt securities, or to otherwise incur outstanding debt following this offering, we may choose to incur substantial debt to complete our business combination. We and our officers have agreed that we will not incur any indebtedness unless we have

Table of Contents

obtained from the lender a waiver of any right, title, interest or claim of any kind in or to the monies held in the trust account. As such, no issuance of debt will affect the per share amount available for redemption from the trust account. Nevertheless, the incurrence of debt could have a variety of negative effects, including:

• default and foreclosure on our assets if our operating revenues after an initial business combination are insufficient to repay our debt obligations;

• acceleration of our obligations to repay the indebtedness even if we make all principal and interest payments when due if we breach certain covenants that require the maintenance of certain financial ratios or reserves without a waiver or renegotiation of that covenant;

• our immediate payment of all principal and accrued interest, if any, if the debt security is payable on demand;

• our inability to obtain necessary additional financing if the debt security contains covenants restricting our ability to obtain such financing while the debt security is outstanding;

• our inability to pay dividends on our ordinary shares;

• using a substantial portion of our cash flow to pay principal and interest on our debt, which will reduce the funds available for dividends on our ordinary shares if declared, to pay expenses, make capital expenditures and acquisitions and fund other general corporate purposes;

• limitations on our flexibility in planning for and reacting to changes in our business and in the industry in which we operate;

• increased vulnerability to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation;

• limitations on our ability to borrow additional amounts for expenses, capital expenditures, acquisitions, debt service requirements, and execution of our strategy; and

• other disadvantages compared to our competitors who have less debt.

We may only be able to complete one business combination with the proceeds of this offering and the sale of the private placement shares, which will cause us to be solely dependent on a single business which may have a limited number of products or services. This lack of diversification may negatively impact our operations and profitability.

Of the net proceeds from this offering and the sale of the private placement shares, up to $309.5 million (or up to $355.4 million if the underwriters’ over-allotment option is exercised in full) will be available to complete our business combination and pay related fees and expenses (which includes approximately $10.5 million, or up to approximately $12.1 million if the over-allotment option is exercised in full, for payment of deferred underwriting discounts and commissions). Of the up to $301.0 million (or up to $346.0 million if the underwriters’ over-allotment option is exercised in full), $1,000,000 will be held outside the trust account for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses.

We may effectuate our business combination with a single target business or multiple target businesses simultaneously or within a short period of time. However, we may not be able to effectuate our business combination with more than one target business because of various factors, including the existence of complex accounting issues and the requirement that we prepare and file pro forma financial statements with the SEC that present operating results and the financial condition of several target businesses as if they had been operated on a combined basis. By completing our initial business combination with only a single entity, our lack of diversification may subject us to numerous economic, competitive and regulatory developments. Further, we would not be able to diversify our operations or benefit from the possible spreading of risks or offsetting of losses, unlike other entities which

Table of Contents

may have the resources to complete several business combinations in different industries or different areas of a single industry. In addition, we intend to focus our search for an initial business combination in a single industry. Accordingly, the prospects for our success may be:

• solely dependent upon the performance of a single business, property or asset, or

• dependent upon the development or market acceptance of a single or limited number of products, processes or services.

This lack of diversification may subject us to numerous economic, competitive and regulatory risks, any or all of which may have a substantial adverse impact upon the particular industry in which we may operate subsequent to our business combination.

We may attempt to simultaneously complete business combinations with multiple prospective targets, which may hinder our ability to complete our business combination and give rise to increased costs and risks that could negatively impact our operations and profitability.

If we determine to simultaneously acquire several businesses that are owned by different sellers, we will need for each of such sellers to agree that our purchase of its business is contingent on the simultaneous closings of the other business combinations, which may make it more difficult for us, and delay our ability, to complete our initial business combination. With multiple business combinations, we could also face additional risks, including additional burdens and costs with respect to possible multiple negotiations and due diligence investigations (if there are multiple sellers) and the additional risks associated with the subsequent assimilation of the operations and services or products of the acquired companies in a single operating business. If we are unable to adequately address these risks, it could negatively impact our profitability and results of operations.

We may attempt to complete our initial business combination with a private company about which little information is available, which may result in a business combination with a company that is not as profitable as we suspected, if at all.

In pursuing our business combination strategy, we may seek to effectuate our initial business combination with a privately held company. Very little public information generally exists about private companies, and we could be required to make our decision on whether to pursue a potential initial business combination on the basis of limited information, which may result in a business combination with a company that is not as profitable as we suspected, if at all.

As the number of special purpose acquisition companies evaluating targets increases, attractive targets may become scarcer and there may be more competition for attractive targets. This could increase the cost of our initial business combination and could even result in our inability to find a target or to consummate an initial business combination.

In recent years, the number of special purpose acquisition companies that have been formed has increased substantially. Many potential targets for special purpose acquisition companies have already entered into an initial business combination, and there are still many special purpose acquisition companies preparing for an initial public offering, as well as many such companies currently in registration. As a result, at times, fewer attractive targets may be available to consummate an initial business combination. In addition, because there are more special purpose acquisition companies seeking to enter into an initial business combination with available targets, the competition for available targets with attractive fundamentals or business models may increase, which could cause targets companies to demand improved financial terms. Attractive deals could also become scarcer for other reasons, such as economic or industry sector downturns, geopolitical tensions, or increases in the cost of additional capital needed to close business combinations or operate targets post-business combination. This could increase the cost of, delay or otherwise complicate or frustrate our ability to find and consummate an initial business combination, and may result in our inability to consummate an initial business combination on terms favorable to our investors altogether.

Table of Contents

In order to effectuate our initial business combination, we may seek to amend our amended and restated memorandum and articles of association or other governing instruments in a manner that will make it easier for us to complete our initial business combination but that our shareholders may not support.

Amending our amended and restated memorandum and articles of association will require at least a special resolution of our shareholders as a matter of Cayman Islands law. In addition, our amended and restated memorandum and articles of association require us to provide our public shareholders with the opportunity to redeem their public shares for cash if we propose an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we do not complete an initial business combination within 24 months (or 27 months, as applicable) of the closing of this offering. To the extent any of such amendments would be deemed to fundamentally change the nature of any of the securities offered through this registration statement, we would register, or seek an exemption from registration for, the affected securities.

In order to effectuate a business combination, we may amend various provisions of our amended and restated memorandum and articles of association and other governing instruments, including the underwriting agreement relating to this offering, the letter agreement among us, Tortoise and our sponsor, officers and directors, and the registration rights agreement among us, Tortoise and our initial shareholders. These agreements contain various provisions that our public shareholders might deem to be material. While we do not expect our board to approve any amendment to any of these agreements prior to our initial business combination, it may be possible that our board, in exercising its business judgment and subject to its fiduciary duties, chooses to approve one or more amendments to any such agreement in connection with the consummation of our initial business combination. Except in relation to the amended and restated memorandum and articles of association, any such amendments would not require approval from our shareholders and may have an adverse effect on the value of an investment in our securities. We cannot assure you that we will not seek to amend our amended and restated memorandum and articles of association or other governing instruments or change our industry focus in order to effectuate our initial business combination.

We may be unable to obtain additional financing to complete our initial business combination or to fund the operations and growth of a target business, which could compel us to restructure or abandon a particular business combination. If we are unable to complete our initial business combination, our public shareholders may only receive their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

Although we believe that the net proceeds of this offering and the sale of the private placement shares will be sufficient to allow us to complete our initial business combination, because we have not yet selected any prospective target business we cannot ascertain the capital requirements for any particular transaction. If the net proceeds of this offering and the sale of the private placement shares prove to be insufficient, either because of the size of our initial business combination, the depletion of the available net proceeds in search of a target business, the obligation to redeem for cash a significant number of shares from shareholders who elect redemption in connection with our initial business combination or the terms of negotiated transactions to purchase shares in connection with our initial business combination, we may be required to seek additional financing or to abandon the proposed business combination. We cannot assure you that such financing will be available on acceptable terms, if at all. To the extent that additional financing proves to be unavailable when needed to complete our initial business combination, we would be compelled to either restructure the transaction or abandon that particular business combination and seek an alternative target business candidate. If we are unable to complete our initial business combination, our public shareholders may only receive their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless. In addition, even if we do not need additional financing to complete our business combination, we may require such financing to fund the operations or growth of the target business. The failure to secure additional financing could have a material adverse effect on the continued development or growth of the target business. None of our officers, directors or shareholders is required to provide any financing to us in connection with or after our business combination.

Because we must furnish our shareholders with target business financial statements, we may lose the ability to complete an otherwise advantageous initial business combination with some prospective target businesses.

The federal proxy rules require that a proxy statement with respect to a vote on a business combination meeting certain financial significance tests include target historical and/or pro forma financial statement disclosure. We will include the same financial statement disclosure in connection with our tender offer documents,

Table of Contents

whether or not they are required under the tender offer rules. These financial statements may be required to be prepared in accordance with, or be reconciled to, accounting principles generally accepted in the United States of America, or U.S. GAAP, or international financial reporting standards as issued by the International Accounting Standards Board, or IFRS, depending on the circumstances and the historical financial statements may be required to be audited in accordance with the standards of the Public Company Accounting Oversight Board (United States), or the PCAOB. These financial statement requirements may limit the pool of potential target businesses we may acquire because some targets may be unable to provide such financial statements in time for us to disclose such financial statements in accordance with federal proxy rules and complete our initial business combination within the prescribed time frame.

Other than amendments relating to the appointment or removal of directors prior to our initial business combination (which require the approval of a majority of at least 90% of our ordinary shares voting at a general meeting), the provisions of our amended and restated memorandum and articles of association that relate to our pre-business combination activity (and corresponding provisions of the agreement governing the release of funds from our trust account) may be amended with the approval of holders of at least two-thirds of our ordinary shares who attend and vote at a general meeting, which is a lower amendment threshold than that of some other blank check companies. It may be easier for us, therefore, to amend our amended and restated memorandum and articles of association and the trust agreement to facilitate the completion of an initial business combination that some of our shareholders may not support.

Some other blank check companies have a provision in their charter which prohibits the amendment of certain of its provisions, including those which relate to a company’s pre-business combination activity, without approval by a certain percentage of the company’s shareholders. In those companies, amendment of these provisions requires approval by between 90% and 100% of the company’s public shareholders. Our amended and restated memorandum and articles of association will provide that any of its provisions (other than amendments relating to the appointment or removal of directors prior to our initial business combination, which require the approval of a majority of at least 90% of our ordinary shares voting at a general meeting) related to pre-business combination activity (including the requirement to deposit proceeds of this offering and the private placement of shares into the trust account and not release such amounts except in specified circumstances, and to provide redemption rights to public shareholders as described herein) may be amended if approved by holders of at least two-thirds of our ordinary shares who attend and vote in a general meeting, and corresponding provisions of the trust agreement governing the release of funds from our trust account may be amended if approved by holders of at least two-thirds of our ordinary shares who attend and vote in a general meeting. Our initial shareholders, who will collectively beneficially own 20% of our ordinary shares upon the closing of this offering (excluding the private placement shares and assuming they do not purchase any shares in this offering), will participate in any vote to amend our amended and restated memorandum and articles of association and/or trust agreement and will have the discretion to vote in any manner they choose. As a result, we may be able to amend the provisions of our amended and restated memorandum and articles of association which govern our pre-business combination behavior more easily than some other blank check companies, and this may increase our ability to complete a business combination with which you do not agree. Our shareholders may pursue remedies against us for any breach of our amended and restated memorandum and articles of association.

Our sponsor, officers, directors and director nominees have agreed, pursuant to a written agreement with us, that they will not propose any amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, unless we provide our public shareholders with the opportunity to redeem their Class A ordinary shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares. These agreements are contained in a letter agreement, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part, that we have entered into with Tortoise and our sponsor, officers, directors and director nominees. Our shareholders are not parties to, or third-party beneficiaries of, these agreements and, as a result, will not have the ability to pursue remedies against Tortoise and our sponsor, officers, directors or director nominees for any breach of these agreements. As a result, in the event of a breach, our shareholders would need to pursue a shareholder derivative action, subject to applicable law.

Table of Contents

After our initial business combination, it is possible that a majority of our directors and officers will live outside the United States and all of our assets will be located outside the United States; therefore investors may not be able to enforce federal securities laws or their other legal rights.

It is possible that after our initial business combination, a majority of our directors and officers will reside outside of the United States and all of our assets will be located outside of the United States. As a result, it may be difficult, or in some cases not possible, for investors in the United States to enforce their legal rights, to effect service of process upon all of our directors or officers or to enforce judgments of United States courts predicated upon civil liabilities and criminal penalties on our directors and officers under United States laws.

Our current officers may not remain in their positions following our business combination. We may have a limited ability to assess the management of a prospective target business and, as a result, may effect our initial business combination with a target business whose management may not have the skills, qualifications or abilities to manage a public company, which could, in turn, negatively impact the value of our shareholders’ investment in us.

When evaluating the desirability of effecting our initial business combination with a prospective target business, our ability to assess the target business’s management may be limited due to a lack of time, resources or information. Our assessment of the capabilities of the target business’s management, therefore, may prove to be incorrect and such management may lack the skills, qualifications or abilities we suspected. Should the target business’s management not possess the skills, qualifications or abilities necessary to manage a public company, the operations and profitability of the post-combination business may be negatively impacted. Accordingly, any shareholders who choose to remain shareholders following the business combination could suffer a reduction in the value of their securities. Such shareholders are unlikely to have a remedy for such reduction in value unless they are able to successfully claim that the reduction was due to the breach by our officers or directors of a duty of care or other fiduciary duty owed to them, or if they are able to successfully bring a private claim under securities laws that the proxy solicitation or tender offer materials (as applicable) relating to the business combination contained an actionable material misstatement or material omission.

The officers and directors of an acquisition candidate may resign upon completion of our initial business combination. The loss of a business combination target’s key personnel could negatively impact the operations and profitability of our post-combination business.

The role of an acquisition candidate’s key personnel upon the completion of our initial business combination cannot be ascertained at this time. Although we contemplate that certain members of an acquisition candidate’s management team will remain associated with the acquisition candidate following our initial business combination, it is possible that members of the management of an acquisition candidate will not wish to remain in place.

Changes in the market for directors’ and officers’ liability insurance could make it more difficult and more expensive for us to negotiate and complete an initial business combination.

In recent months, the market for directors’ and officers’ liability insurance for special purpose acquisition companies has changed in ways adverse to us and our management team. Fewer insurance companies are offering quotes for directors’ and officers’ liability coverage, the premiums charged for such policies have generally increased and the terms of such policies have generally become less favorable. These trends may continue into the future.

The increased cost and decreased availability of directors’ and officers’ liability insurance could make it more difficult and more expensive for us to negotiate an initial business combination. In order to obtain directors’ and officers’ liability insurance or modify its coverage as a result of becoming a public company, the post-business combination entity might need to incur greater expense, accept less favorable terms or both. However, any failure to obtain adequate directors’ and officers’ liability insurance could have an adverse impact on the post-business combination’s ability to attract and retain qualified officers and directors.

In addition, even after we were to complete an initial business combination, our directors and officers could still be subject to potential liability from claims arising from conduct alleged to have occurred prior to the initial business combination. As a result, in order to protect our directors and officers, the post-business combination entity may need to purchase additional insurance with respect to any such claims (“run-off insurance”). The need for run-off insurance would be an added expense for the post-business combination entity, and could interfere with or frustrate our ability to consummate an initial business combination on terms favorable to our investors.

Table of Contents

If we are unable to consummate our initial business combination within 24 months (or 27 months, as applicable) of the closing of this offering, our public shareholders may be forced to wait beyond such 24 months (or 27 months, as applicable) before redemption from our trust account.

If we are unable to consummate our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, we will distribute the aggregate amount then on deposit in the trust account (less up to $100,000 of the net interest earned thereon to pay dissolution expenses), pro rata to our public shareholders by way of redemption and cease all operations except for the purposes of winding up of our affairs, as further described herein. Any redemption of public shareholders from the trust account shall be effected automatically by function of our amended and restated memorandum and articles of association prior to any voluntary winding up. If we are required to windup, liquidate the trust account and distribute such amount therein, pro rata, to our public shareholders, as part of any liquidation process, such winding up, liquidation and distribution must comply with the applicable provisions of the Companies Act. In that case, investors may be forced to wait beyond the initial 24 months (or 27 months, as applicable) before the redemption proceeds of our trust account become available to them and they receive the return of their pro rata portion of the proceeds from our trust account. We have no obligation to return funds to investors prior to the date of our redemption or liquidation unless we consummate our initial business combination prior thereto and only then in cases where investors have sought to redeem their ordinary shares. Only upon our redemption or any liquidation will public shareholders be entitled to distributions if we are unable to complete our initial business combination.

Resources could be wasted in researching business combinations that are not completed, which could materially adversely affect subsequent attempts to locate and acquire or merge with another business. If we are unable to complete our initial business combination, our public shareholders may only receive their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

We anticipate that the investigation of each specific target business and the negotiation, drafting and execution of relevant agreements, disclosure documents and other instruments will require substantial management time and attention and substantial costs for accountants, attorneys, consultants and others. If we decide not to complete a specific initial business combination, the costs incurred up to that point for the proposed transaction likely would not be recoverable. Furthermore, if we reach an agreement relating to a specific target business, we may fail to complete our initial business combination for any number of reasons including those beyond our control. Any such event will result in a loss to us of the related costs incurred which could materially adversely affect subsequent attempts to locate and acquire or merge with another business. If we are unable to complete our initial business combination, our public shareholders may only receive their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

If we pursue a target business with operations or opportunities outside of the United States for our initial business combination, we may face additional burdens in connection with investigating, agreeing to and completing such initial business combination, and if we effect such an initial business combination, we would be subject to a variety of additional risks that may negatively impact our operations.

If we pursue a target company with operations or opportunities outside of the United States for our initial business combination, we would be subject to risks associated with cross-border business combinations, including in connection with investigating, agreeing to and completing our initial business combination, conducting due diligence in a foreign jurisdiction, having such transaction approved by any local governments, regulators or agencies and changes in the purchase price based on fluctuations in foreign exchange rates.

If we effect our initial business combination with such a company, we would be subject to special considerations or risks associated with companies operating in an international setting, including any of the following:

• higher costs and difficulties inherent in executing cross-border transactions, managing cross-border business operations and complying with different commercial and legal requirements of overseas markets;

• rules and regulations regarding currency redemption;

Table of Contents

• laws governing the manner in which future business combinations may be effected;

• exchange listing and/or delisting requirements;

• tariffs and trade barriers;

• regulations related to customs and import/export matters;

• local or regional economic policies and market conditions;

• unexpected changes in regulatory requirements;

• longer payment cycles;

• tax issues, including complex withholding or other tax regimes which may apply in connection with our busines combination or to our structure following our business combination, variations in tax laws as compared to the United States, and potential changes in the applicable tax laws in the United States and/or relevant non-U.S. jurisdictions;

• currency fluctuations and exchange controls;

• rates of inflation;

• challenges in collecting accounts receivable;

• cultural and language differences;

• employment regulations;

• underdeveloped or unpredictable legal or regulatory systems;

• corruption;

• protection of intellectual property;

• social unrest, crime, strikes, riots and civil disturbances;

• regime changes and political upheaval;

• terrorist attacks, natural disasters and wars;

• deterioration of political relations with the United States; and

• government appropriation of assets.

We may not be able to adequately address these additional risks. If we were unable to do so, we may be unable to complete such initial business combination, or, if we complete such combination, our operations might suffer, either of which may adversely impact our business, financial condition and results of operations.

If our management following our initial business combination is unfamiliar with United States securities laws, they may have to expend time and resources becoming familiar with such laws, which could lead to various regulatory issues.

Following our initial business combination, our management may resign from their positions as officers or directors of the company and the management of the target business at the time of the business combination may remain in place. Management of the target business may not be familiar with United States securities laws. If new management is unfamiliar with United States securities laws, they may have to expend time and resources becoming familiar with such laws. This could be expensive and time-consuming and could lead to various regulatory issues which may adversely affect our operations.

Table of Contents

After our initial business combination, substantially all of our assets may be located in a foreign country and substantially all of our revenue will be derived from our operations in such country. Accordingly, our results of operations and prospects will be subject, to a significant extent, to the economic, political and legal policies, developments and conditions in the country in which we operate.

The economic, political and social conditions, as well as government policies, of the country in which our operations are located could affect our business. Economic growth could be uneven, both geographically and among various sectors of the economy and such growth may not be sustained in the future. If in the future such country’s economy experiences a downturn or grows at a slower rate than expected, there may be less demand for spending in certain industries. A decrease in demand for spending in certain industries could materially and adversely affect our ability to find an attractive target business with which to consummate our initial business combination and if we effect our initial business combination, the ability of that target business to become profitable.

Exchange rate fluctuations and currency policies may cause a target business’ ability to succeed in the international markets to be diminished.

In the event we acquire a non-U.S. target, all revenues and income would likely be received in a foreign currency, and the dollar equivalent of our net assets and distributions, if any, could be adversely affected by reductions in the value of the local currency. The value of the currencies in non-U.S. regions fluctuates and is affected by, among other things, changes in political and economic conditions. Any change in the relative value of such currency against our reporting currency may affect the attractiveness of any target business or, following consummation of our initial business combination, our financial condition and results of operations. Additionally, if a currency appreciates in value against the dollar prior to the consummation of our initial business combination, the cost of a target business as measured in dollars will increase, which may make it less likely that we are able to consummate such transaction.

If we acquire a non-U.S. target, our results of operations may be negatively impacted because of the costs and difficulties inherent in managing cross-border business operations.

We may pursue a target company with operations or opportunities outside of the United States for our initial business combination. Managing a business, operations, personnel or assets in another country is challenging and costly. Any management that we may have (whether based abroad or in the U.S.) may be inexperienced in cross-border business practices and unaware of significant differences in accounting rules, legal regimes and labor practices. Even with a seasoned and experienced management team, the costs and difficulties inherent in managing cross-border business operations, personnel and assets can be significant (and much higher than in a purely domestic business) and may negatively impact our financial and operational performance.

If social unrest, acts of terrorism, regime changes, changes in laws and regulations, political upheaval or policy changes or enactments occur in a country in which we may operate after we effect our initial business combination, it may result in a negative impact on our business.

In the event we acquire a non-U.S. target, political events in another country may significantly affect our business, assets or operations. Social unrest, acts of terrorism, regime changes, changes in laws and regulations, political upheaval, and policy changes or enactments could negatively impact our business in a particular country.

Many countries have difficult and unpredictable legal systems and underdeveloped laws and regulations that are unclear and subject to corruption and inexperience, which may adversely impact our results of operations and financial condition.

In the event we acquire a non-U.S. target, our ability to seek and enforce legal protections, including with respect to intellectual property and other property rights, or to defend ourselves with regard to legal actions taken against us in a given country, may be difficult or impossible, which could adversely impact our operations, assets or financial condition.

Rules and regulations in many countries are often ambiguous or open to differing interpretation by responsible individuals and agencies at the municipal, state, regional and federal levels. The attitudes and actions of such individuals and agencies are often difficult to predict and inconsistent.

Table of Contents

Delay with respect to the enforcement of particular rules and regulations, including those relating to customs, tax, environmental and labor, could cause serious disruption to operations abroad and negatively impact our results.

Because foreign law could govern almost all of our material agreements, we may not be able to enforce our rights within such jurisdiction or elsewhere, which could result in a significant loss of business, business opportunities or capital.

In the event we acquire a non-U.S. target, foreign law could govern almost all of our material agreements. The target business may not be able to enforce any of its material agreements or enforce remedies for breaches of those agreements outside of such foreign jurisdiction’s legal system. The system of laws and the enforcement of existing laws and contracts in such jurisdiction may not be as certain in implementation and interpretation as in the United States. As a result, the inability to enforce or obtain a remedy under any of our future agreements could result in a significant loss of business and business opportunities.

We may reincorporate in another jurisdiction in connection with our initial business combination, and the laws of such jurisdiction may govern some or all of our future material agreements and we may not be able to enforce our legal rights.

In connection with our initial business combination, we may relocate the home jurisdiction of our business from the Cayman Islands to another jurisdiction. If we determine to do this, the laws of such jurisdiction may govern some or all of our future material agreements. The system of laws and the enforcement of existing laws in such jurisdiction may not be as certain in implementation and interpretation as in the United States. The inability to enforce or obtain a remedy under any of our future agreements could result in a significant loss of business, business opportunities or capital.

Our amended and restated memorandum and articles of association will require the affirmative vote of a majority of our board of directors, which must include a majority of our independent directors and each of the non-independent directors nominated by our sponsor, to approve our initial business combination. Accordingly, it is unlikely that we will be able to enter into an initial business combination unless our sponsor’s members find the target and the business combination attractive. This may make it more difficult for us to approve and enter into an initial business combination than other blank check companies and could result in us not pursuing an acquisition target or other board or corporate action that our public shareholders would find favorable.

Risks Relating to our Securities

You will not have any rights or interests in funds from the trust account, except under certain limited circumstances. Therefore, to liquidate your investment, you may be forced to sell your public shares, potentially at a loss.

Our public shareholders will be entitled to receive funds from the trust account only upon the earliest to occur of: (i) the redemption of any public shares properly submitted in connection with our completion of an initial business combination (including the release of funds to pay any amounts due to any public shareholders who properly exercise their redemption rights in connection therewith), (ii) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would modify the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, and (iii) the redemption of our public shares if we are unable to complete an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law and as further described herein. In no other circumstances will a public shareholder have any right or interest of any kind in the trust account. Accordingly, to liquidate your investment, you may be forced to sell your public shares, potentially at a loss.

Table of Contents

The NYSE may delist our securities from trading on its exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions.

We intend to apply to have our Class A ordinary shares listed on the NYSE on or promptly after the date of this prospectus. Although after giving effect to this offering we expect to meet, on a pro forma basis, the minimum initial listing standards set forth in the NYSE listing standards, we cannot assure you that our securities will be, or will continue to be, listed on the NYSE in the future or prior to our initial business combination. In order to continue listing our securities on the NYSE prior to our initial business combination, we must maintain certain financial, distribution and share price levels. Generally, we must maintain a minimum number of holders of our securities (generally 300 round lot holders).

Additionally, in connection with our initial business combination, we will be required to demonstrate compliance with the NYSE’s initial listing requirements, which are more rigorous than the NYSE’s continued listing requirements, in order to continue to maintain the listing of our securities on the NYSE. For instance, our share price would generally be required to be at least $4.00 per share, our aggregate market value would be required to be at least $100 million, and the market value of our publicly-held shares would be required to be at least $80 million. We cannot assure you that we will be able to meet those initial listing requirements at that time.

If the NYSE delists our securities from trading on its exchange and we are not able to list our securities on another national securities exchange, we expect our securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

• a limited availability of market quotations for our securities;

• reduced liquidity for our securities;

• a determination that our Class A ordinary shares are a “penny stock” which will require brokers trading in our Class A ordinary shares to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

• a limited amount of news and analyst coverage; and

• a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Because we expect that our Class A ordinary shares will be listed on the NYSE, our Class A ordinary shares will be covered securities under the statute. Although the states are preempted from regulating the sale of our securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. While we are not aware of a state having used these powers to prohibit or restrict the sale of securities issued by blank check companies, other than the state of Idaho, certain state securities regulators view blank check companies unfavorably and might use these powers, or threaten to use these powers, to hinder the sale of securities of blank check companies in their states. Further, if we were no longer listed on the NYSE, our securities would not be covered securities under the statute and we would be subject to regulation in each state in which we offer our securities.

You will not be entitled to protections normally afforded to investors of many other blank check companies.

Since the net proceeds of this offering and the sale of the private placement shares are intended to be used to complete an initial business combination with a target business that has not been selected, we may be deemed to be a “blank check” company under the United States securities laws. However, because we will have net tangible assets in excess of $5,000,000 upon the successful completion of this offering and the sale of the private placement shares and will file a Current Report on Form 8-K, including an audited balance sheet demonstrating this fact, we are exempt from rules promulgated by the SEC to protect investors in blank check companies, such as Rule 419. Accordingly, investors will not be afforded the benefits or protections of those rules. Among other things, this means our public shares will be immediately tradable and we will have a longer period of time to complete our business combination than do companies subject to Rule 419. Moreover, if this offering were subject to Rule 419, that rule would prohibit the release of any interest earned on funds held in the trust account to us unless and until the funds in the trust account were released to us in connection with our completion of an initial business combination.

If third parties bring claims against us, the proceeds held in the trust account could be reduced and the per-share redemption amount received by shareholders may be less than $10.00 per share.

Our placing of funds in the trust account may not protect those funds from third-party claims against us. Although we will seek to have all vendors, service providers (other than our independent registered public accounting firm), prospective target businesses and other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the trust account for the benefit of our public shareholders, such parties may not execute such agreements, or even if they execute such agreements, they may not be prevented from bringing claims against the trust account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain an advantage with respect to a claim against our assets, including the funds held in the trust account. If any third party refuses to execute an agreement waiving such claims to the monies held in the trust account, our management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to us than any alternative. Making such a request of potential target businesses may make our acquisition proposal less attractive to them and, to the extent prospective target businesses refuse to execute such a waiver, it may limit the field of potential target businesses that we might pursue.

Examples of possible instances where we may engage a third party that refuses to execute a waiver include the engagement of a third-party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the trust account for any reason. Upon redemption of our public shares, if we are unable to complete our initial business combination within the prescribed timeframe, or upon the exercise of a redemption right in connection with our business combination, we will be required to provide for payment of claims of creditors that were not waived that may be brought against us within the 10 years following redemption. Accordingly, the per-share redemption amount received by public shareholders could be less than the $10.00 per public share initially held in the trust account, due to claims of such creditors. Pursuant to the letter agreement the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part, our sponsor has agreed that it will be liable to us if and to the extent any claims by a third party (other than our independent public accountants) for services rendered or products sold to us, or a prospective target business with which we have entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the trust account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account, if less than $10.00 per share due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay our taxes, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the trust account (whether or not such waiver is enforceable) nor will it apply to any claims under our indemnity of the underwriters of this offering against certain liabilities, including liabilities under the Securities Act. However, we have not asked our sponsor to reserve for such indemnification obligations, nor have we independently verified whether our sponsor has sufficient funds to satisfy its indemnity obligations and we believe that our sponsor’s only assets are securities of our company. Therefore, we cannot assure you that our sponsor would be able to satisfy those obligations. As a result, if any such claims were successfully made against the trust account, the funds available for our initial business combination and redemptions could be reduced to less than $10.00 per public share. In such event, we may not be able to complete our initial business combination, and you would receive such lesser amount per share in connection with any redemption of your public shares. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Table of Contents

Our directors may decide not to enforce the indemnification obligations of our sponsor, resulting in a reduction in the amount of funds in the trust account available for distribution to our public shareholders.

In the event that the proceeds in the trust account are reduced below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account, if less than $10.00 per share due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay our taxes, and our sponsor asserts that it is unable to satisfy its obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against our sponsor to enforce its indemnification obligations.

While we currently expect that our independent directors would take legal action on our behalf against our sponsor to enforce its indemnification obligations to us, it is possible that our independent directors in exercising their business judgment, and subject where relevant to their fiduciary duties, may choose not to do so in any particular instance. If our independent directors choose not to enforce these indemnification obligations, the amount of funds in the trust account available for distribution to our public shareholders may be reduced below $10.00 per share.

If, after we distribute the proceeds in the trust account to our public shareholders, we file a winding up petition or a winding up petition is filed against us that is not dismissed, a liquidator may seek to recover such proceeds, and the members of our board of directors may be viewed as having breached their fiduciary duties to our creditors, thereby potentially exposing the members of our board of directors and us to claims of punitive damages.

If, after we distribute the proceeds in the trust account to our public shareholders, we file a winding up petition or a winding up petition is filed against us that is not dismissed, any distributions received by shareholders could be viewed under applicable debtor/creditor and/or insolvency laws as a “voidable preference.” As a result, a liquidator could seek to challenge the transaction and recover some or all amounts received by our shareholders. In addition, our board of directors may be viewed as having breached its fiduciary duty to our creditors and/or having acted in bad faith, thereby exposing itself and us to claims of punitive damages, by paying public shareholders from the trust account prior to addressing the claims of creditors.

If, before distributing the proceeds in the trust account to our public shareholders, we file a winding up petition or a winding up petition is filed against us that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of our shareholders and the per-share amount that would otherwise be received by our shareholders in connection with our liquidation may be reduced.

If, before distributing the proceeds in the trust account to our public shareholders, we file a winding up petition or a winding up petition is filed against us that is not dismissed, the proceeds held in the trust account could be subject to applicable insolvency law, and may be included in our liquidation estate and subject to the claims of third parties with priority over the claims of our shareholders. To the extent any liquidation claims deplete the trust account, the per-share amount that would otherwise be received by our shareholders in connection with our liquidation may be reduced.

If we are deemed to be an investment company under the Investment Company Act, we may be required to institute burdensome compliance requirements and our activities may be restricted, which may make it difficult for us to complete our business combination.

If we are deemed to be an investment company under the Investment Company Act, our activities may be restricted, including:

• restrictions on the nature of our investments; and

• restrictions on the issuance of securities, each of which may make it difficult for us to complete our business combination.

In addition, we may have imposed upon us burdensome requirements, including:

• registration as an investment company;

• adoption of a specific form of corporate structure; and

• reporting, record keeping, voting, proxy and disclosure requirements and other rules and regulations.

Table of Contents

In order not to be regulated as an investment company under the Investment Company Act, unless we can qualify for an exclusion, we must ensure that we are engaged primarily in a business other than investing, reinvesting or trading of securities and that our activities do not include investing, reinvesting, owning, holding or trading “investment securities” constituting more than 40% of our assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. Our business will be to identify and complete a business combination and thereafter to operate the post-transaction business or assets for the long term. We do not plan to buy businesses or assets with a view to resale or profit from their resale. We do not plan to buy unrelated businesses or assets or to be a passive investor.

We do not believe that our anticipated principal activities will subject us to the Investment Company Act. To this end, the proceeds held in the trust account may only be invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Pursuant to the trust agreement, the trustee is not permitted to invest in other securities or assets. By restricting the investment of the proceeds to these instruments, and by having a business plan targeted at acquiring and growing businesses for the long term (rather than on buying and selling businesses in the manner of a merchant bank or private equity fund), we intend to avoid being deemed an “investment company” within the meaning of the Investment Company Act. This offering is not intended for persons who are seeking a return on investments in government securities or investment securities. The trust account is intended as a holding place for funds pending the earliest to occur of: (i) the completion of our initial business combination; (ii) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering; and (iii) the redemption of our public shares if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law. If we do not invest the proceeds as discussed above, we may be deemed to be subject to the Investment Company Act. If we were deemed to be subject to the Investment Company Act, compliance with these additional regulatory burdens would require additional expenses for which we have not allotted funds and may hinder our ability to complete a business combination, or may result in our liquidation. If we are unable to complete our initial business combination, our public shareholders may only receive their pro rata portion of the funds in the trust account that are available for distribution to public shareholders, and our private placement shares will be worthless.

Our shareholders may be held liable for claims by third parties against us to the extent of distributions received by them upon redemption of their shares.

If we are forced to enter into an insolvent liquidation, any distributions received by shareholders could be viewed as an unlawful payment if it was proved that immediately following the date on which the distribution was made, we were unable to pay our debts as they fall due in the ordinary course of business. As a result, a liquidator could seek to recover some or all amounts received by our shareholders. Furthermore, our directors may be viewed as having breached their fiduciary duties to us or our creditors and/or may have acted in bad faith, thereby exposing themselves and our company to claims, by paying public shareholders from the trust account prior to addressing the claims of creditors. We cannot assure you that claims will not be brought against us for these reasons. We and our directors and officers who knowingly and willfully authorized or permitted any distribution to be paid out of our share premium account while we were unable to pay our debts as they fall due in the ordinary course of business would be guilty of an offence and may be liable to a fine and to imprisonment in the Cayman Islands or both. We may not hold an annual general meeting until after the consummation of our initial business combination, which could delay the opportunity for our shareholders to appoint directors.

We may not hold an annual general meeting until after the consummation of our initial business combination, which could delay the opportunity for our shareholders to appoint directors.

In accordance with the NYSE corporate governance requirements, we are not required to hold an annual general meeting until no later than one year after our first fiscal year end following our listing on the NYSE. There is no requirement under the Companies Act for us to hold annual or general meetings to appoint directors. Until we

Table of Contents

hold an annual general meeting, public shareholders may not be afforded the opportunity to appoint directors and to discuss company affairs with management. Our board of directors is divided into three classes with only one class of directors being elected in each year and each class (except for those directors appointed prior to our first annual general meeting) serving a three-year term.

The grant of registration rights to our initial shareholders may make it more difficult to complete our initial business combination, and the future exercise of such rights may adversely affect the market price of our Class A ordinary shares.

Pursuant to an agreement to be entered into concurrently with the issuance and sale of the securities in this offering, we have agreed with our initial shareholders and Tortoise to register the Class A ordinary shares into which founder shares are convertible, the private placement shares, any Class A ordinary shares held upon the completion of this offering or acquired prior to or in connection with our initial business combination and shares that may be issued upon conversion of working capital loans. Assuming the founder shares convert on a one for one basis, no shares are issued upon conversion of working capital loans and our initial shareholders or Tortoise do not hold any Class A ordinary shares at the completion of this offering or acquire any shares prior to or in connection with our initial business combination, an aggregate of up to 7,500,000 Class A ordinary shares and up to 950,000 private placement shares (or up to 8,625,000 Class A ordinary shares and up to 1,040,000 private placement shares if the over-allotment option is exercised in full) are subject to registration under these agreements.

We will bear the cost of registering these securities. The registration and availability of such a significant number of securities for trading in the public market may have an adverse effect on the market price of our Class A ordinary shares. In addition, the existence of the registration rights may make our initial business combination more costly or difficult to conclude. This is because the shareholders of the target business may increase the equity stake they seek in the combined entity or ask for more cash consideration to offset the negative impact on the market price of our Class A ordinary shares that is expected when the securities owned by our initial shareholders, Tortoise or their respective permitted transferees are registered.

Our private placement shares and founder shares may have an adverse effect on the market price of our Class A ordinary shares and make it more difficult to effectuate our business combination.

Simultaneously with the closing of this offering, we will be issuing in a private placement an aggregate of 950,000 (or up to 1,040,000 if the underwriters’ over-allotment option is exercised in full) private placement shares, at $10.00 per share.

The founder shares are convertible into Class A ordinary shares on a one-for-one basis, subject to adjustment for share sub-divisions, share dividends, reorganizations, recapitalizations and the like and subject to further adjustment as set forth herein. In addition, if our sponsor makes any working capital loans, it may convert those loans into up to an additional 150,000 private placement shares, at the price of $10.00 per share. To the extent we issue Class A ordinary shares to effectuate a business combination, the potential for the issuance of a substantial number of additional Class A ordinary shares upon conversion rights could make us a less attractive acquisition vehicle to a target business. Any such issuance will increase the number of issued and outstanding Class A ordinary shares and reduce the value of the Class A ordinary shares issued to complete the business combination. Therefore, our private placement shares and founder shares may make it more difficult to effectuate a business combination or increase the cost of acquiring the target business.

The determination of the offering price of our Class A ordinary shares and the size of this offering is more arbitrary than the pricing of securities and size of an offering of an operating company in a particular industry. You may have less assurance, therefore, that the offering price of our Class A ordinary shares properly reflects the value of such Class A ordinary shares than you would have in a typical offering of an operating company.

Prior to this offering, there has been no public market for any of our securities. The public offering price of the Class A ordinary shares was negotiated between us and the underwriters. In determining the size of this offering, management held customary organizational meetings with representatives of the underwriters, both prior to our

Table of Contents

inception and thereafter, with respect to the state of capital markets, generally, and the amount the underwriters believed they reasonably could raise on our behalf. Factors considered in determining the size of this offering, prices and terms of the Class A ordinary shares include:

• the history and prospects of companies whose principal business is the acquisition of other companies;

• prior offerings of those companies;

• our prospects for acquiring an operating business at attractive values;

• a review of debt to equity ratios in leveraged transactions;

• our capital structure;

• an assessment of our management and their experience in identifying operating companies;

• general conditions of the securities markets at the time of this offering; and

• other factors as were deemed relevant.

Although these factors were considered, the determination of our offering price is more arbitrary than the pricing of securities of an operating company in a particular industry since we have no historical operations or financial results.

We do not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for us to complete a business combination with which a substantial majority of our shareholders do not agree.

Our amended and restated memorandum and articles of association will not provide a specified maximum redemption threshold, except that in no event will we redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (such that we are not subject to the SEC’s “penny stock” rules). As a result, we may be able to complete our business combination even though a substantial majority of our public shareholders do not agree with the transaction and have redeemed their shares or, if we seek shareholder approval of our initial business combination and do not conduct redemptions in connection with our business combination pursuant to the tender offer rules, have entered into privately negotiated agreements to sell their shares to our sponsor, officers, directors, advisors or any of their affiliates. In the event the aggregate cash consideration we would be required to pay for all Class A ordinary shares that are validly submitted for redemption plus any amount required to satisfy cash conditions pursuant to the terms of the proposed business combination exceed the aggregate amount of cash available to us, we will not complete the business combination or redeem any shares, all Class A ordinary shares submitted for redemption will be returned to the holders thereof, and we instead may search for an alternate business combination.

There is currently no market for our securities and a market for our securities may not develop, which would adversely affect the liquidity and price of our securities.

There is currently no market for our securities. Shareholders therefore have no access to information about prior market history on which to base their investment decision. Following this offering, the price of our securities may vary significantly due to one or more potential business combinations and general market or economic conditions. Furthermore, an active trading market for our securities may never develop or, if developed, it may not be sustained. You may be unable to sell your securities unless a market can be established and sustained.

We may not have sufficient funds to satisfy indemnification claims of our directors and officers.

We have agreed to indemnify our officers and directors to the fullest extent permitted by law. However, our officers and directors have agreed, and any persons who may become officers or directors prior to the initial business combination will agree, to waive any right, title, interest or claim of any kind in or to any monies in the trust account and to not seek recourse against the trust account for any reason whatsoever. Accordingly, any indemnification provided will be able to be satisfied by us only if (i) we have sufficient funds outside of the trust account or

Table of Contents

(ii) we consummate an initial business combination. Our obligation to indemnify our officers and directors may discourage shareholders from bringing a lawsuit against our officers or directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against our officers and directors, even though such an action, if successful, might otherwise benefit us and our shareholders. Furthermore, a shareholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against our officers and directors pursuant to these indemnification provisions.

The securities in which we invest the funds held in the trust account could bear a negative rate of interest, which could reduce the value of the assets held in trust such that the per-share redemption amount received by public shareholders may be less than $10.00 per share. In addition, we may elect to hold our trust funds in cash for such period of time as we may determine in our discretion, in which case no interest will be earned on our trust funds during such period.

The proceeds held in the trust account will be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act, which invest only in direct U.S. government treasury obligations. While short-term U.S. government treasury obligations currently yield a positive rate of interest, they have briefly yielded negative interest rates in recent years. Central banks in Europe and Japan pursued interest rates below zero in recent years, and the Open Market Committee of the Federal Reserve has not ruled out the possibility that it may in the future adopt similar policies in the United States. In the event that we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) after the closing of this offering, then we will, among other things, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (net of any taxes payable by us and less up to $100,000 of interest to pay dissolution expenses), divided by the number of then-outstanding public shares. Negative interest rates could reduce the value of the assets held in trust such that the per-share redemption amount received by public shareholders may be less than $10.00 per share. In addition, we may elect to hold our trust funds in cash for such period of time as we may determine in our discretion, in which case no interest will be earned on our trust funds during such period.

Unlike some other similarly structured blank check companies, our initial shareholders will receive additional Class A ordinary shares if we issue shares to consummate an initial business combination.

The founder shares will automatically convert into Class A ordinary shares at the time of our initial business combination on a one-for-one basis, subject to adjustment for share sub-divisions, share dividends, reorganizations, recapitalizations and the like and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares or equity-linked securities convertible or exercisable for Class A ordinary shares are issued or deemed issued in excess of the amounts sold in this offering and related to the closing of our initial business combination, the ratio at which founder shares will convert into Class A ordinary shares will be adjusted so that the number of Class A ordinary shares issuable upon conversion of all founder shares will equal, in the aggregate 20% of the sum of our ordinary shares outstanding upon completion of this offering plus the number of Class A ordinary shares and equity-linked securities issued or deemed issued in connection with our initial business combination, excluding any Class A ordinary shares or equity-linked securities issued, or to be issued, to any seller in our initial business combination.

We may be treated as a passive foreign investment company (“PFIC”), which could result in adverse U.S. federal income tax consequences to U.S. investors.

If we are treated as a PFIC for any taxable year (or portion thereof) in which a U.S. Holder (as defined in the section of this prospectus captioned “Certain Income Tax Considerations — U.S. Federal Income Tax Considerations — U.S. Holder and Non-U.S. Holder Defined”) holds our Class A ordinary shares (regardless of whether we remain a PFIC for subsequent taxable years), such U.S. Holder may be subject to certain adverse U.S. federal income tax consequences and may be subject to additional reporting requirements. Our PFIC status for our current and subsequent taxable years may depend on, among other things, whether we qualify for the PFIC start-up exception, the timing of our business combination, the amount of our passive income and assets in the year of the business combination, whether we combine with a U.S. or non-U.S. target company, and the amount of passive income and assets of the acquired business. Our actual PFIC status for our current taxable year or any subsequent

Table of Contents

taxable year will not be determinable until after the end of such taxable year (and in the case of our start-up year, possibly not until after the close of the second taxable year following our start-up year). We cannot assure you that we will not be a PFIC in our current taxable year or in any future taxable year.

If we determine we are a PFIC for any taxable year, upon written request by a U.S. Holder, we will endeavor to provide to such U.S. Holder such information as the Internal Revenue Service (the “IRS”) may require, including a PFIC annual information statement, in order to enable such U.S. Holder to make and maintain a “qualified electing fund” (“QEF”) election with respect to its Class A ordinary shares, but there is no assurance that we will timely provide such required information. The rules dealing with PFICs and with the QEF election are very complex and are affected by various factors in addition to those described in this prospectus. Accordingly, U.S. investors are strongly urged to consult with and rely solely upon their own tax advisors regarding the application of the PFIC rules to them in their particular circumstances.

For a more detailed discussion of the PFIC rules and the related tax considerations for U.S. Holders, see the section of this prospectus captioned “Certain Income Tax Considerations — U.S. Federal Income Tax Considerations — Considerations for U.S. Holders — Passive Foreign Investment Company Rules.”

An investment in our Class A ordinary shares, and certain subsequent transactions with respect to our Class A ordinary shares, may result in uncertain or adverse U.S. federal income tax consequences.

An investment in our Class A ordinary shares, and certain subsequent transactions with respect to our Class A ordinary shares, may result in uncertain or adverse U.S. federal income tax consequences. For instance, it is unclear whether the redemption rights with respect to our Class A ordinary shares suspend the running of a U.S. Holder’s holding period for purposes of determining whether any gain or loss realized by such holder on the sale or exchange of Class A ordinary shares is long-term capital gain or loss and for determining whether any dividend we pay would be eligible for favorable U.S. federal income tax treatment. See “Certain Income Tax Considerations — U.S. Federal Income Tax Considerations” below for a summary of the principal U.S. federal income tax consequences of an investment in our Class A ordinary shares. Each prospective investor is urged to consult with and rely solely upon its own tax advisors with respect to these and other tax consequences when purchasing, holding or disposing of our Class A ordinary shares.

The U.S. federal income tax treatment of the redemption of Class A ordinary shares as a sale of such Class A ordinary shares depends on a shareholder’s specific facts.

The U.S. federal income tax treatment of a redemption of Class A ordinary shares will depend on whether the redemption qualifies as a sale of such Class A ordinary shares under Section 302(a) of the Code, which will depend largely on the total number of ordinary shares treated as held by the shareholder electing to redeem Class A ordinary shares relative to all of the ordinary shares outstanding before and after the redemption. If such redemption is not treated as a sale of Class A ordinary shares for U.S. federal income tax purposes, the redemption will instead be treated as a corporate distribution.

Provisions in our amended and restated memorandum and articles of association may inhibit a takeover of us, which could limit the price investors might be willing to pay in the future for our Class A ordinary shares and could entrench management.

Our amended and restated memorandum and articles of association will contain provisions that may discourage unsolicited takeover proposals that shareholders may consider to be in their best interests. These provisions include a staggered board of directors and the ability of the board of directors to designate the terms of and issue new series of preference shares, which may make the removal of management more difficult and may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities.

Because, unlike many other initial public offerings by special purpose acquisition companies, investors in this offering will not receive warrants that would become exercisable following the completion of our initial business combination, our securities offered may be worth less than the securities offered in other initial public offerings by special purpose acquisition companies.

This is an initial public offering of our Class A ordinary shares. Unlike many other initial public offerings by special purpose acquisition companies, investors in this offering will not receive warrants that would become exercisable following the completion of our initial business combination. We are not offering warrants in order to remove the dilutive effect of warrants upon completion of an initial business combination, thus making us, we believe, a more attractive business combination partner for target businesses. Nevertheless, this offering structure may cause our offered securities to be worth less than if we were also offering a whole or fractional warrant to purchase shares.

Risks Relating to our Sponsor and Management Team

Past performance by our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, the Tortoise Funds, Lightfoot Capital, and by companies affiliated with celebrities or public figures, and any related investment may not be indicative of future performance of an investment in us.

Information regarding performance by, or businesses associated with, our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, the Tortoise Funds, Lightfoot Capital and any related investment is presented for informational purposes only. Past performance by our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, the Tortoise Funds, Lightfoot Capital and any related investment is not a guarantee either (i) of success with respect to any business combination we may consummate or (ii) that we will be able to locate a suitable candidate for our initial business combination. Additionally, the involvement of a celebrity or public figure in any business venture does not guarantee success with respect to any business combination we may consummate or that we will be able to locate a suitable candidate for our initial business combination. You should not rely on the historical record of our management team, Tortoise Acquisition II, Tortoise Acquisition I, Tortoise, the Tortoise Funds, Lightfoot Capital and any related investment’s performance as indicative of our future performance or of an investment in us or the returns we will, or are likely to, generate going forward.

We may seek acquisition opportunities outside of our target industries or sectors (which industries or sectors may or may not be outside of our management’s areas of expertise).

Although we intend to focus on identifying business combination candidates in the broad energy transition or sustainability arena targeting industries that require innovative solutions to decarbonize in order to meet critical emission reduction objectives, we will consider a business combination outside of our target industries or sectors if a business combination candidate is presented to us and we determine that such candidate offers an attractive acquisition opportunity for our company or we are unable to identify a suitable candidate in our target industries or sectors after having expended a reasonable amount of time and effort in an attempt to do so. Although our management will endeavor to evaluate the risks inherent in any particular business combination candidate, we cannot assure you that we will adequately ascertain or assess all of the significant risk factors. We also cannot assure you that an investment in our Class A ordinary shares will not ultimately prove to be less favorable to investors in this offering than a direct investment, if an opportunity were available, in a business combination candidate. In the event we elect to pursue an acquisition outside of our target industries or sectors, our management’s expertise may not be directly applicable to its evaluation or operation, and the information contained in this prospectus regarding our target industries or sectors would not be relevant to an understanding of the business that we elect to acquire. As a result, our management may not be able to adequately ascertain or assess all of the significant risk factors. Accordingly, any shareholders who choose to remain shareholders following our business combination could suffer a reduction in the value of their shares. Such shareholders are unlikely to have a remedy for such reduction in value.

Our ability to successfully effect our initial business combination and to be successful thereafter will be totally dependent upon the efforts of our key personnel, some of whom may join us following our initial business combination. The loss of key personnel could negatively impact the operations and profitability of our post-combination business.

Our ability to successfully effect our business combination is dependent upon the efforts of our key personnel. The role of our key personnel in the target business, however, cannot presently be ascertained. Although some of our key personnel may remain with the target business in senior management or advisory positions following our

Table of Contents

business combination, it is likely that some or all of the management of the target business will remain in place. While we intend to closely scrutinize any individuals we engage after our initial business combination, we cannot assure you that our assessment of these individuals will prove to be correct. These individuals may be unfamiliar with the requirements of operating a company regulated by the SEC, which could cause us to have to expend time and resources helping them become familiar with such requirements.

In addition, the officers and directors of an acquisition candidate may resign upon completion of our initial business combination. The departure of a business combination target’s key personnel could negatively impact the operations and profitability of our post-combination business. The role of an acquisition candidate’s key personnel upon the completion of our initial business combination cannot be ascertained at this time. Although we contemplate that certain members of an acquisition candidate’s management team will remain associated with the acquisition candidate following our initial business combination, it is possible that members of the management of an acquisition candidate will not wish to remain in place. The loss of key personnel could negatively impact the operations and profitability of our post-combination business.

Our key personnel may negotiate employment or consulting agreements with a target business in connection with a particular business combination, and a particular business combination may be conditioned on the retention or resignation of such key personnel. These agreements may provide for them to receive compensation following our business combination and as a result, may cause them to have conflicts of interest in determining whether a particular business combination is the most advantageous.

Our key personnel may be able to remain with our company after the completion of our business combination only if they are able to negotiate employment or consulting agreements in connection with the business combination. Such negotiations would take place simultaneously with the negotiation of the business combination and could provide for such individuals to receive compensation in the form of cash payments and/or our securities for services they would render to us after the completion of the business combination. Such negotiations also could make such key personnel’s retention or resignation a condition to any such agreement. The personal and financial interests of such individuals may influence their motivation in identifying and selecting a target business.

Certain of our officers and directors are now, and all of them may in the future become, affiliated with entities engaged in business activities similar to those intended to be conducted by us, including another blank check company, and, accordingly, may have conflicts of interest in allocating their time and determining to which entity a particular business opportunity should be presented.

Following the completion of this offering and until we consummate our initial business combination, we intend to engage in the business of identifying and combining with one or more businesses. Our sponsor and officers and directors are, and may in the future become, affiliated with entities that are engaged in a similar business, including another blank check company that may have acquisition objectives that are similar to ours. For example, certain of our officers and directors currently serve in similar roles for Tortoise Acquisition II, a blank check company incorporated as a Cayman Islands exempted company and formed for the purpose of effecting its own initial business combination. Mr. Cubbage is the President, Chief Executive Officer and Chairman of the Board of directors of Tortoise Acquisition II, Mr. Pang is the Chief Financial Officer and a director of Tortoise Acquisition II and Messrs. Brock, Zimmer and Schnitzer are, respectively, Vice President, Business Development, Vice President, Finance and Vice President, General Counsel and Secretary of Tortoise Acquisition II, and each such officer and director owes fiduciary duties under Cayman Islands law to Tortoise Acquisition II.

Our officers and directors also may become aware of business opportunities which may be appropriate for presentation to us and the other entities to which they owe certain fiduciary or contractual duties. Accordingly, they may have conflicts of interest in determining to which entity a particular business opportunity should be presented. These conflicts may not be resolved in our favor and a potential target business may be presented to another entity prior to its presentation to us. Our amended and restated memorandum and articles of association will provide that we renounce our interest in any corporate opportunity offered to any director or officer unless such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of our company and such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue, and to the extent the director or officer is permitted to refer that opportunity to us without violating another legal obligation.

Table of Contents

For a complete discussion of our officers’ and directors’ business affiliations and the potential conflicts of interest that you should be aware of, please see “Management — Directors and Officers,” “Management — Conflicts of Interest” and “Certain Relationships and Related Party Transactions.”

Our officers, directors, security holders and their respective affiliates may have competitive pecuniary interests that conflict with our interests.

We have not adopted a policy that expressly prohibits our directors, officers, security holders or affiliates (including affiliates of our sponsor and their respective employees) from having a direct or indirect pecuniary or financial interest in any investment to be acquired or disposed of by us or in any transaction to which we are a party or have an interest. In fact, we may enter into a business combination with a target business that is affiliated with our sponsor, our directors or officers, although we do not intend to do so, or we may acquire a target business through an Affiliated Joint Acquisition with one or more affiliates of Tortoise and/or one or more investors in the Tortoise Funds. We do not have a policy that expressly prohibits any such persons from engaging for their own account in business activities of the types conducted by us, including the formation of, or participation in, one or more other blank check companies. Accordingly, such persons or entities may have a conflict between their interests and ours.

In particular, certain of the Tortoise Funds are focused on investments in areas of sustainability, energy transition, infrastructure, water and clean energy. As a result, there may be substantial overlap between companies that would be a suitable business combination for us and companies that would make an attractive target for the Tortoise Funds. The personal and financial interests of our directors and officers may influence their motivation in timely identifying and selecting a target business and completing a business combination. Consequently, our directors’ and officers’ discretion in identifying and selecting a suitable target business may result in a conflict of interest when determining whether the terms, conditions and timing of a particular business combination are appropriate and in our best interests. If this were the case and the directors fail to act in accordance with their fiduciary duties owed to us as a matter of Cayman Islands law, we may have a claim against such individuals. For further information on the ability to bring such claims, please see “Description of Securities — Certain Differences in Corporate Law — Shareholders’ Suits.” However, we might not ultimately be successful in any claim we may make against them for such reason.

We may engage in a business combination with one or more target businesses that have relationships with entities that may be affiliated with our sponsor, officers, directors or Tortoise which may raise potential conflicts of interest.

In light of the involvement of our sponsor, officers and directors with other entities, we may decide to acquire one or more businesses affiliated with our sponsor, officers, directors or Tortoise. Our officers and directors also serve as officers and board members for other entities, including, without limitation, those described under “Management — Conflicts of Interest.” They may also have investments in target businesses. Such entities may compete with us for business combination opportunities. Our sponsor, officers and directors are not currently aware of any specific opportunities for us to complete our business combination with any entities with which they are affiliated, and there have been no preliminary discussions concerning a business combination with any such entity or entities. Although we will not be specifically focusing on, or targeting, any transaction with any affiliated entities, we would pursue such a transaction if we determined that such affiliated entity met our criteria for a business combination as set forth in “Proposed Business — Selection of a Target Business and Structuring of our Initial Business Combination” and such transaction was approved by a majority of our independent and disinterested directors. Despite our obligation to obtain an opinion from an independent investment banking firm that is a member of FINRA or from an independent accounting firm regarding the fairness to our company from a financial point of view of a business combination with one or more domestic or international businesses affiliated with our sponsor, officers or directors, potential conflicts of interest still may exist and, as a result, the terms of the business combination may not be as advantageous to our public shareholders as they would be absent any conflicts of interest.

Moreover, we may pursue an Affiliated Joint Acquisition opportunity with an entity affiliated with Tortoise and/or one or more investors in the Tortoise Funds. Any such parties may co-invest with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the business combination by issuing to such parties a class of equity or equity-linked securities. Accordingly, such persons or entities may have a conflict between their interests and ours.

Table of Contents

Since our sponsor, officers and directors will lose their entire investment in us if our business combination is not completed (other than with respect to public shares they may acquire during or after this offering), a conflict of interest may arise in determining whether a particular business combination target is appropriate for our initial business combination.

In February 2021, 7,187,500 founder shares were issued to our sponsor in exchange for the payment of $25,000 of expenses on our behalf, or approximately $0.003 per share. On February 18, 2021, we issued 1,437,500 Class B ordinary shares to our sponsor in connection with a share capitalization, resulting in our sponsor holding an aggregate of 8,625,000 founder shares. Prior to the initial investment in the company of $25,000 by our sponsor, the company had no assets, tangible or intangible. The per share price of the founder shares was determined by dividing the amount contributed to the company by the number of founder shares issued. The number of founder shares issued was determined based on the expectation that the total size of this offering would be a maximum of 34,500,000 Class A ordinary shares if the underwriters’ over-allotment option is exercised in full, and therefore that such founder shares would represent 20% of the outstanding shares after this offering (excluding the private placement shares). Our sponsor will forfeit up to 1,125,000 founder shares depending on the extent to which the underwriters’ over-allotment option is not exercised. The founder shares will be worthless if we do not complete an initial business combination. In connection with this offering, our sponsor will forfeit a total of 120,000 founder shares, and 40,000 founder shares will then be issued to each of our independent directors, William J. Clinton, Juan J. Daboub and Mary Beth Mandanas, at their original purchase price. In addition, Tortoise has committed, pursuant to a written agreement, to purchase an aggregate of 950,000 (or 1,040,000 if the underwriters’ over-allotment option is exercised in full) private placement shares, at $10.00 per share, for an aggregate purchase price of approximately $9,500,000 (or approximately $10,400,000 if the underwriters’ over-allotment option is exercised in full), or $10.00 per share, that will also be worthless if we do not complete a business combination. The founder shares are identical to the Class A ordinary shares being sold in this offering, except that only holders of the founder shares have the right to vote on the appointment or removal of directors prior to our initial business combination and they are Class B ordinary shares that automatically convert into our Class A ordinary shares at the time of our initial business combination on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights, as described herein. However, the holders have agreed (A) to vote any shares owned by them in favor of any proposed business combination and (B) not to redeem any founder shares in connection with a shareholder vote to approve a proposed initial business combination. In addition, we may obtain loans from our sponsor, affiliates of our sponsor or an officer or director. The personal and financial interests of our officers and directors may influence their motivation in identifying and selecting a target business combination, completing an initial business combination and influencing the operation of the business following our initial business combination. This risk may become more acute as the 24-month (or 27-month, as applicable) anniversary of the closing of this offering nears, which is the deadline for our completion of an initial business combination.

Our management may not be able to maintain control of a target business after our initial business combination. We cannot provide assurance that, upon loss of control of a target business, new management will possess the skills, qualifications or abilities necessary to profitably operate such business.

We may structure a business combination so that the post-transaction company in which our public shareholders own shares will own less than 100% of the equity interests or assets of a target business, but we will only complete such business combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires an interest in the target sufficient for the post-transaction company not to be required to register as an investment company under the Investment Company Act. We will not consider any transaction that does not meet such criteria. Even if the post-transaction company owns 50% or more of the voting securities of the target, our shareholders prior to the business combination may collectively own a minority interest in the post business combination company, depending on valuations ascribed to the target and us in the business combination transaction. For example, we could pursue a transaction in which we issue a substantial number of new shares in exchange for all of the outstanding capital stock, shares or other equity interests of a target. In this case, we would acquire a 100% interest in the target. However, as a result of the issuance of a substantial number of new shares, our shareholders immediately prior to such transaction could own less than a majority of our outstanding ordinary shares subsequent to such transaction. In addition, other minority shareholders may subsequently combine their holdings resulting in a single person or group obtaining a larger share of the company’s shares than we initially acquired. Accordingly, this may make it more likely that our management will not be able to maintain control of the target business.

Table of Contents

Our initial shareholders will control the appointment of our board of directors until consummation of our initial business combination and will hold a substantial interest in us. As a result, they will appoint and remove all of our directors prior to our initial business combination and may exert a substantial influence on actions requiring a shareholder vote, potentially in a manner that you do not support.

Upon the closing of this offering, our initial shareholders will own shares representing 20% of our issued and outstanding ordinary shares (excluding the private placement shares and assuming they do not purchase any shares in this offering). In addition, the founder shares, all of which are held by our initial shareholders, will entitle the holders to appoint and remove all of our directors prior to our initial business combination. In respect of any vote or votes to continue the company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction), which requires the approval of at least two-thirds of the votes of all ordinary shares, holders of our founder shares are entitled to ten votes for every founder share. Holders of our public shares will have no right to vote on the appointment or removal of directors during such time. These provisions of our amended and restated memorandum and articles of association may only be amended by a special resolution passed by a majority of at least 90% of our ordinary shares voting in a general meeting. As a result, you will not have any influence over the appointment or removal of directors prior to our initial business combination. Accordingly, our initial shareholders may exert a substantial influence on actions requiring a shareholder vote, potentially in a manner that you do not support, including amendments to our amended and restated memorandum and articles of association and approval of major corporate transactions. If our initial shareholders purchase any Class A ordinary shares in this offering or if our initial shareholders purchase any additional ordinary shares in the aftermarket or in privately negotiated transactions, this would increase their control. Neither our initial shareholders nor, to our knowledge, any of our officers or directors have any current intention to purchase additional securities, other than as disclosed in this prospectus. Factors that would be considered in making such additional purchases would include consideration of the current trading price of our Class A ordinary shares. In addition, our board of directors, whose members were elected by our initial shareholders, is and will be divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. We may not hold an annual general meeting to appoint new directors prior to the completion of our business combination, in which case all of the current directors will continue in office until at least the completion of the business combination. If there is an annual general meeting, as a consequence of our “staggered” board of directors, only a minority of the board of directors will be considered for appointment and our initial shareholders, because of their ownership position, will have considerable influence regarding the outcome. Accordingly, our initial shareholders will continue to exert control at least until the completion of our business combination.

Our sponsor paid an aggregate of $25,000, or approximately $0.003 per founder share, and, accordingly, you will experience immediate and substantial dilution from the purchase of our Class A ordinary shares to the benefit of our sponsor and certain of our directors and officers.

The difference between the public offering price per share and the pro forma net tangible book value per share of our Class A ordinary shares after this offering constitutes the dilution to you and the other investors in this offering. Our sponsor acquired the founder shares at a nominal price, significantly contributing to this dilution. Upon the closing of this offering, you and the other public shareholders will incur an immediate and substantial dilution of approximately 94.9% (or $9.49 per share, assuming no exercise of the underwriters’ over-allotment option), the difference between the pro forma net tangible book value per share after this offering of $0.51 and the initial offering price of $10.00 per share. This dilution would increase to the extent that the anti-dilution provisions of the founder shares result in the issuance of Class A ordinary shares on a greater than one-to-one basis upon conversion of the founder shares at the time of our initial business combination and would become exacerbated to the extent that public shareholders seek redemptions from the trust for their public shares. In addition, because of the anti-dilution protection in the founder shares, any equity or equity-linked securities issued in connection with our initial business combination would be disproportionately dilutive to our Class A ordinary shares. Moreover, although we are of the view that our sponsor, directors and officers paid fair value for the founder shares, there is no assurance that a taxing authority would agree with us, and if a taxing authority were to successfully assert otherwise, we may be subject to material withholding and other tax liabilities that could adversely affect our financial condition.

Table of Contents

We are dependent upon our officers and directors, and their loss could adversely affect our ability to operate.

Our operations are dependent upon a relatively small group of individuals and, in particular, our officers and directors. We believe that our success depends on the continued service of our officers and directors, at least until we have completed our initial business combination. In addition, our officers and directors are not required to commit any specified amount of time to our affairs and, accordingly, will have conflicts of interest in allocating their time among various business activities, including identifying potential business combinations and monitoring the related due diligence. We do not have an employment agreement with, or key-man insurance on the life of, any of our directors or officers. The unexpected loss of the services of one or more of our directors or officers could have a detrimental effect on us.

Our officers and directors will allocate their time to other businesses thereby causing conflicts of interest in their determination as to how much time to devote to our affairs. This conflict of interest could have a negative impact on our ability to complete our initial business combination.

Our officers and directors are not required to, and will not, commit their full time to our affairs, which may result in a conflict of interest in allocating their time between our operations and our search for a business combination and their other businesses. We do not intend to have any full-time employees prior to the completion of our initial business combination. Each of our officers is engaged in several other business endeavors for which he may be entitled to substantial compensation, and our officers are not obligated to contribute any specific number of hours per week to our affairs. In particular, all of the members of our management team and certain of our directors are employed by Tortoise or affiliates of Tortoise, which is an investment manager to various private investment funds which may make investments in companies that we may target for our initial business combination. Our independent directors may also serve as officers or board members for other entities. If our officers’ and directors’ other business affairs require them to devote substantial amounts of time to such affairs in excess of their current commitment levels, it could limit their ability to devote time to our affairs which may have a negative impact on our ability to complete our initial business combination. For a complete discussion of our officers’ and directors’ other business affairs, please see “Management — Officers, Directors and Director Nominees,” “Management — Conflicts of Interest” and “Certain Relationships and Related Party Transactions.”

Since our sponsor paid only approximately $0.003 per share for the founder shares, our officers and directors could potentially make a substantial profit even if we acquire a target business that subsequently declines in value.

In February 2021, our sponsor purchased an aggregate of 7,187,500 founder shares for an aggregate purchase price of $25,000, or approximately $0.003 per share. On February 18, 2021, we issued 1,437,500 Class B ordinary shares to our sponsor in connection with a share capitalization, resulting in our sponsor holding an aggregate of 8,625,000 founder shares. Our officers and directors have a significant economic interest (directly or indirectly, including through family trusts) in our sponsor. As a result, the low acquisition cost of the founder shares creates an economic incentive whereby our officers and directors could potentially make a substantial profit even if we acquire a target business that subsequently declines in value and is unprofitable for public investors.

Because we are incorporated under the laws of the Cayman Islands, you may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. federal courts may be limited.

We are an exempted company incorporated under the laws of the Cayman Islands. As a result, it may be difficult for investors to effect service of process within the United States upon our directors or executive officers, or enforce judgments obtained in the United States courts against our directors or officers.

Our corporate affairs will be governed by our amended and restated memorandum and articles of association, the Companies Act and the common law of the Cayman Islands. We will also be subject to the federal securities laws of the United States. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from English common law, the decisions of whose courts are of persuasive authority, but are not binding on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are different

Table of Contents

from what they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a different body of securities laws as compared to the United States, and certain states, such as Delaware, may have more fully developed and judicially interpreted bodies of corporate law. In addition, Cayman Islands companies may not have standing to initiate a shareholders derivative action in a Federal court of the United States.

We have been advised by Walkers, 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, or to the extent they 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, 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.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a United States company.

General Risk Factors

We may issue additional ordinary shares or preference shares to complete our initial business combination or under an employee incentive plan after completion of our initial business combination. We may also issue Class A ordinary shares upon the conversion of the Class B ordinary shares at a ratio greater than one-to-one at the time of our initial business combination as a result of the anti-dilution provisions contained in our amended and restated memorandum and articles of association. Any such issuances would dilute the interest of our shareholders and likely present other risks.

Our amended and restated memorandum and articles of association will authorize the issuance of up to 200,000,000 Class A ordinary shares, par value $0.0001 per share, 20,000,000 Class B ordinary shares, par value $0.0001 per share, and 1,000,000 undesignated preference shares, par value $0.0001 per share. Immediately after this offering, there will be 169,050,000 and 12,500,000 (assuming, in each case, that the underwriters have not exercised their over-allotment option) authorized but unissued Class A ordinary shares and Class B ordinary shares, respectively, available for issuance, which amount does not take into account the shares issuable upon conversion of Class B ordinary shares. Our Class B ordinary shares are automatically convertible into Class A ordinary shares at the time of our initial business combination, initially at a one-for-one ratio but subject to adjustment and forfeiture as set forth herein. Immediately after the consummation of this offering, there will be no preference shares issued and outstanding. Class B ordinary shares are convertible into our Class A ordinary shares initially at a one-for-one ratio but subject to adjustment as set forth herein, including in certain circumstances in which we issue Class A ordinary shares or equity-linked securities related to our initial business combination.

We may issue a substantial number of additional ordinary shares or preference shares to complete our initial business combination or under an employee incentive plan after completion of our initial business combination. We may also issue Class A ordinary shares upon conversion of the Class B ordinary shares at a ratio greater than one-to-one at the time of our initial business combination as a result of the anti-dilution provisions contained in our amended and restated memorandum and articles of association. However, our amended and restated memorandum and articles of association will provide, among other things, that prior to our initial business combination, we may not issue additional ordinary shares that would entitle the holders thereof to (i) receive funds from the trust account

Table of Contents

or (ii) vote on any initial business combination. These provisions of our amended and restated memorandum and articles of association, like all provisions of our amended and restated memorandum and articles of association, may be amended with a shareholder vote. The issuance of additional ordinary shares or preference shares:

• may significantly dilute the equity interest of investors in this offering;

• may subordinate the rights of holders of ordinary shares if preference shares are issued with rights senior to those afforded our ordinary shares;

• could cause a change in control if a substantial number of ordinary shares are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and could result in the resignation or removal of our present officers and directors; and

• may adversely affect prevailing market prices for our Class A ordinary shares.

Cyber incidents or attacks directed at us could result in information theft, data corruption, operational disruption and/or financial loss.

We depend on digital technologies, including information systems, infrastructure and cloud applications and services, including those of third parties with which we may deal. Sophisticated and deliberate attacks on, or security breaches in, our systems or infrastructure, or the systems or infrastructure of third parties or the cloud, could lead to corruption or misappropriation of our assets, proprietary information and sensitive or confidential data. As an early stage company without significant investments in data security protection, we may not be sufficiently protected against such occurrences. We may not have sufficient resources to adequately protect against, or to investigate and remediate any vulnerability to, cyber incidents. It is possible that any of these occurrences, or a combination of them, could have adverse consequences on our business and lead to financial loss.

We are an emerging growth company and a smaller reporting company within the meaning of the Securities Act, and if we take advantage of certain exemptions from disclosure requirements available to emerging growth companies or smaller reporting companies, this could make our securities less attractive to investors and may make it more difficult to compare our performance with other public companies.

We are an “emerging growth company” within the meaning of the Securities Act, as modified by the JOBS Act, and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As a result, our shareholders may not have access to certain information they may deem important. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if the market value of our Class A ordinary shares held by non-affiliates exceeds $700 million as of any June 30 before that time, in which case we would no longer be an emerging growth company as of the following December 31. We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of our

financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Compliance obligations under the Sarbanes-Oxley Act may make it more difficult for us to effectuate our business combination, require substantial financial and management resources, and increase the time and costs of completing our initial business combination.

Section 404 of the Sarbanes-Oxley Act requires that we evaluate and report on our system of internal controls beginning with our Annual Report on Form 10-K for the fiscal year ending December 31, 2022. Only in the event we are deemed to be a large accelerated filer or an accelerated filer will we be required to comply with the independent registered public accounting firm attestation requirement on our internal control over financial reporting. Further, for as long as we remain an emerging growth company, we will not be required to comply with the independent registered public accounting firm attestation requirement on our internal control over financial reporting. The fact that we are a blank check company makes compliance with the requirements of the Sarbanes-Oxley Act particularly burdensome on us as compared to other public companies because a target business with which we seek to complete our business combination may not be in compliance with the provisions of the Sarbanes-Oxley Act regarding adequacy of its internal controls. The development of the internal control of any such entity to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete any such acquisition.

____________

(1) Includes amounts payable to public shareholders who properly redeem their shares in connection with our successful completion of our initial business combination.

(2) A portion of the offering expenses will be paid from the proceeds of loans from our sponsor of up to $600,000 as described in this prospectus. To date, we have borrowed approximately $118,000 under the note. These loans will be repaid upon completion of this offering out of the $2,500,000 of offering proceeds that has been allocated for the payment of offering expenses (other than underwriting discounts and commissions) and amounts not to be held in the trust account. In the event that offering expenses are less than set forth in this table, any such amounts will be used for post-closing working capital expenses. In the event that the offering expenses are more than as set forth in this table, we may fund such excess with funds not held in the trust account.

Table of Contents

(3) The underwriters have agreed to defer underwriting discounts and commissions equal to 3.5% of the gross proceeds of this offering. Upon completion of our initial business combination, $10,500,000, which constitutes the underwriters’ deferred underwriting discounts and commissions (or $12,075,000 if the underwriters’ over-allotment option is exercised in full), will be paid to the underwriters from the funds held in the trust account, and the remaining funds, less amounts released to the trustee to pay redeeming shareholders, will be released to us and can be used to pay all or a portion of the purchase price of the business or businesses with which our initial business combination occurs or for general corporate purposes, including payment of principal or interest on indebtedness incurred in connection with our initial business combination, to fund the purchases of other companies or for working capital. The underwriters will not be entitled to any interest accrued on the deferred underwriting discounts and commissions.

At our request, the underwriters have agreed to reserve up to 100,000 of the Class A ordinary shares offered by this prospectus for sale to certain members of Tortoise, at the initial public offering price. We do not know if individual investors will choose to purchase all or any portion of these reserved Class A ordinary shares, but any purchases they do make will reduce the number of Class A ordinary shares available in the overall offering. This table assumes that no Class A ordinary shares are sold in the Directed Shares Program.

(4) These expenses are estimates only. Our actual expenditures for some or all of these items may differ from the estimates set forth herein. For example, we may incur greater legal and accounting expenses than our current estimates in connection with negotiating and structuring our business combination based upon the level of complexity of such business combination. In the event we identify a business combination target in a specific industry subject to specific regulations, we may incur additional expenses associated with legal due diligence and the engagement of special legal counsel. In addition, our staffing needs may vary and as a result, we may engage a number of consultants to assist with legal and financial due diligence. We do not anticipate any change in our intended use of proceeds, other than fluctuations among the current categories of allocated expenses, which fluctuations, to the extent they exceed current estimates for any specific category of expenses, would not be available for our expenses. The amount in the table above does not include interest available to us from the trust account. The proceeds held in the trust account will be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations. Based on current interest rates, we would expect the trust account to generate approximately $90,000 of interest annually, assuming an interest rate of 0.03% per year; however, we can provide no assurances regarding this amount.

(5) Includes estimated amounts that may also be used in connection with our business combination to fund a “no shop” provision and commitment fees for financing.

The rules of the NYSE provide that at least 90% of the gross proceeds from this offering and the private placement be deposited in a trust account. Of the net proceeds of this offering and the sale of the private placement shares, $300,000,000 (or $345,000,000 if the underwriters’ over-allotment option is exercised in full), including $10,500,000 (or $12,075,000 if the underwriters’ over-allotment option is exercised in full) of deferred underwriting discounts and commissions, will be deposited into a U.S.-based trust account at J.P. Morgan Chase Bank, N.A. with Continental Stock Transfer & Trust Company acting as trustee, and approximately $9,500,000, or approximately $10,400,000 if the underwriters’ over-allotment option is exercised in full, will be used to pay expenses in connection with the closing of this offering and for working capital following this offering. The proceeds held in the trust account will be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations. Based on current interest rates, we estimate that the interest earned on the trust account will be approximately $90,000 per year, assuming an interest rate of 0.03% per year; however, we can provide no assurances regarding this amount. Except with respect to interest earned on the funds held in the trust account that may be released to us to pay our taxes, the proceeds from this offering and the sale of the private placement shares will not be released from the trust account until the earliest to occur of (a) the completion of our initial business combination (including the release of funds to pay any amounts due to any public shareholders who properly exercise their redemption rights in connection therewith), (b) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we do not complete an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering and (c) the redemption of our public shares if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law. Based on current interest rates, we expect that interest earned on the trust account will be sufficient to pay our taxes.

The net proceeds held in the trust account may be used as consideration to pay the sellers of a target business with which we ultimately complete our business combination. If our initial business combination is paid for using equity or debt securities, or not all of the funds released from the trust account are used for payment of the

Table of Contents

consideration in connection with our business combination, we may apply the balance of the cash released from the trust account for general corporate purposes, including for maintenance or expansion of operations of the post-transaction company, the payment of principal or interest due on indebtedness incurred in completing our initial business combination, to fund the purchase of other companies or for working capital. There is no limitation on our ability to raise funds privately or through loans in connection with our initial business combination.

We believe that amounts not held in trust will be sufficient to pay the costs and expenses to which such proceeds are allocated. This belief is based on the fact that while we may begin preliminary due diligence of a target business in connection with an indication of interest, we intend to undertake in-depth due diligence, depending on the circumstances of the relevant prospective acquisition, only after we have negotiated and signed a letter of intent or other preliminary agreement that addresses the terms of a business combination. However, if our estimate of the costs of undertaking in-depth due diligence and negotiating a business combination is less than the actual amount necessary to do so, we may be required to raise additional capital, the amount, availability and cost of which is currently unascertainable. If we are required to seek additional capital, we could seek such additional capital through loans or additional investments from our sponsor, members of our management team or any of their affiliates, but such persons are not under any obligation to advance funds to, or invest in, us.

We will reimburse Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, for office space, utilities, secretarial support and administrative services provided to members of our management team, in an amount equal to $10,000 per month. Upon completion of our initial business combination or our liquidation, we will cease paying these monthly fees.

Prior to the closing of this offering, our sponsor has agreed to loan us up to $600,000 to be used for a portion of the expenses of this offering. To date, we have borrowed approximately $118,000 under the note. These loans are non-interest bearing, unsecured and are due at the closing of this offering. The loan will be repaid upon the closing of this offering as part of the estimated $2,500,000 of offering expenses.

In addition, in order to finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete our initial business combination, we would repay such loaned amounts out of the proceeds of the trust account released to us. Otherwise, such loans would be repaid only out of funds held outside the trust account. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from our trust account would be used to repay such loaned amounts. Up to $1,500,000 of such loans may be convertible into shares of the post business combination entity at a price of $10.00 per share at the option of the lender. The shares would be identical to the private placement shares, including as to exercise price, exercisability and exercise period. Except as set forth above, the terms of such loans, if any, have not been determined and no written agreements exist with respect to such loans. Prior to the completion of our initial business combination, we do not expect to seek loans from parties other than our sponsor or an affiliate of our sponsor as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our trust account.

If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our business combination pursuant to the tender offer rules, our sponsor, directors, officers, advisors or their affiliates may purchase shares in privately negotiated transactions either prior to or following the completion of our initial business combination. There is no limit on the number of shares our sponsor, directors, officers, advisors or their affiliates may purchase in such transactions, subject to compliance with applicable law and the rules of the NYSE. However, they have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions. If they engage in such transactions, they will not make any such purchases when they are in possession of any material non-public information not disclosed to the seller or if such purchases are prohibited by Regulation M under the Exchange Act. Subsequent to the consummation of this offering, we will adopt an insider trading policy which will require insiders to: (1) refrain from purchasing securities during certain blackout periods and when they are in possession of any material non-public information; and (2) to clear all trades with our legal counsel prior to execution. We cannot currently determine whether our insiders will make such purchases pursuant to a Rule 10b5-1 plan, as it will be dependent upon several factors, including but not limited to, the timing and size of such purchases. Depending on such circumstances, our insiders may either make such purchases pursuant to a Rule 10b5-1 plan or determine that such a plan is not necessary.

Table of Contents

We do not currently anticipate that such purchases, if any, would constitute a tender offer subject to the tender offer rules under the Exchange Act or a going-private transaction subject to the going-private rules under the Exchange Act; however, if the purchasers determine at the time of any such purchases that the purchases are subject to such rules, the purchasers will comply with such rules.

We may not redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (so that we are not subject to the SEC’s “penny stock” rules) and the agreement for our business combination may require as a closing condition that we have a minimum net worth or a certain amount of cash. If too many public shareholders exercise their redemption rights so that we cannot satisfy the net tangible asset requirement or any net worth or cash requirements, we would not proceed with the redemption of our public shares or the business combination, and instead may search for an alternate business combination.

A public shareholder will be entitled to receive funds from the trust account only upon the earliest to occur of: (i) the redemption of any public shares properly submitted in connection with our completion of an initial business combination, (ii) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering and (iii) the redemption of our public shares if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law and as further described herein and any limitations (including but not limited to cash requirements) created by the terms of the proposed business combination. In no other circumstances will a public shareholder have any right or interest of any kind to or in the trust account.

Tortoise and our sponsor, officers and directors will not be entitled to redemption rights with respect to any founder shares, private placement shares or public shares held by them in connection with the completion of our initial business combination. In addition, Tortoise and our sponsor, officers and directors will not be entitled to rights to liquidating distributions from the trust account with respect to any founder shares or private placement shares held by them if we fail to complete our business combination within the prescribed time frame. However, if our sponsor or any of our officers, directors or affiliates acquires public shares in or after this offering, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within the prescribed time frame.

Dividend Policy

We have not paid any cash dividends on our ordinary shares to date and do not intend to pay cash dividends prior to the completion of our initial business combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial condition subsequent to completion of our initial business combination. The payment of any cash dividends subsequent to our initial business combination will be within the discretion of our board of directors at such time. On February 18, 2021, we issued 1,437,500 Class B ordinary shares to our sponsor in connection with a share capitalization, resulting in our sponsor holding an aggregate of 8,625,000 founder shares. In addition, our board of directors is not currently contemplating and does not anticipate declaring any other share dividends in the foreseeable future, except if we increase or decrease the size of this offering, in which case we will effect a share dividend or other appropriate mechanism immediately prior to the consummation of this offering in an amount necessary to maintain the number of founder shares at 20% of our issued and outstanding ordinary shares upon the consummation of this offering. Further, if we incur any indebtedness in connection with our business combination, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

Table of Contents

Dilution

The difference between the public offering price per share of Class A ordinary shares and the pro forma net tangible book value per share of our Class A ordinary shares after this offering constitutes the dilution to investors in this offering. Net tangible book value per share is determined by dividing our net tangible book value, which is our total tangible assets less total liabilities (including the value of Class A ordinary shares which may be redeemed for cash), by the number of outstanding our Class A ordinary shares.

At February 9, 2021, our net tangible book value was a deficit of $(104,621), or approximately $(0.01) per share of ordinary shares. After giving effect to the sale of 30,000,000 Class A ordinary shares we are offering by this prospectus (or 34,500,000 Class A ordinary shares if the underwriters’ over-allotment option is exercised in full), the sale of the private placement shares and the deduction of underwriting discounts and commissions and estimated expenses of this offering, our pro forma net tangible book value at February 9, 2021 would have been $5,000,009, or approximately $0.51 per share (or $5,000,009, or $0.44 per share if the underwriters’ over-allotment option is exercised in full), representing an immediate increase in net tangible book value (as decreased by the value of the 28,551,537 Class A ordinary shares that may be redeemed for cash, or 32,894,037 Class A ordinary shares if the underwriters’ over-allotment option is exercised in full) of $0.52 per share (or $0.45 per share if the underwriters’ over-allotment option is exercised in full) to our initial shareholders as of the date of this prospectus. Total dilution to public shareholders from this offering will be $9.49 per share (or $9.56 per share if the underwriters’ over-allotment option is exercised in full).

The following table illustrates the dilution to the public shareholders on a per-share basis:

	Without Over-Allotment					With Over-Allotment
Public offering price			$	10.00				$	10.00
Net tangible book deficit before this offering	(0.01	)				(0.01	)
Increase attributable to public shareholders	0.52					0.45
Pro forma net tangible book value after this offering and the sale of the private placement shares				0.51					0.44
Dilution to public shareholders			$	9.49				$	9.56
Percentages of dilution to public shareholders				94.9	%				95.6	%

For purposes of presentation, we have reduced our pro forma net tangible book value after this offering (assuming no exercise of the underwriters’ over-allotment option) by $285,515,370 because holders of up to approximately 95.2% of our public shares may redeem their shares for a pro rata share of the aggregate amount then on deposit in the trust account at a per share redemption price equal to the amount in the trust account as set forth in our proxy solicitation or tender offer materials, as applicable (initially anticipated to be the aggregate amount held in trust two days prior to the commencement of our shareholders’ meeting or tender offer, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes), divided by the number of Class A ordinary shares sold in this offering.

The following table sets forth information with respect to our initial shareholders and the public shareholders:

	Shares Purchased			Total Consideration				Average Price Per Share
	Number	Percentage		Amount		Percentage		Average Price Per Share
Initial Shareholders(1)	7,500,000	19.5	%	$	25,000	0.008	%	$	0.003
Private Placement Shares	950,000	2.5	%	$	9,500,000	3.07	%	$	10.000
Public Shareholders	30,000,000	78.0	%	$	300,000,000	96.92	%	$	10.000

(1) Expenses applied against gross proceeds include offering expenses of $2,500,000 and underwriting discounts and commissions of $6,000,000 (or $6,900,000 if the underwriters’ over-allotment option is exercised in full) (excluding deferred underwriting discounts and commissions). See “Use of Proceeds.”

(2) If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our sponsor, directors, executive officers, advisors or their affiliates may purchase shares in privately negotiated transactions or in the open market either prior to or following the completion of our initial business combination. In the event of any such purchases of our shares prior to the completion of our initial business combination, the number of Class A ordinary shares subject to redemption will be reduced by the amount of any such purchases, increasing the pro forma net tangible book value per share. See “Proposed Business — Permitted Purchases of Our Securities.”

(2) At our request, the underwriters have agreed to reserve up to 100,000 of the Class A ordinary shares offered by this prospectus for sale to certain members of Tortoise, at the initial public offering price. We do not know if individual investors will choose to purchase all or any portion of these reserved Class A ordinary shares, but any purchases they do make will reduce the number of Class A ordinary shares available in the overall offering. This table assumes that no Class A ordinary shares are sold in the Directed Shares Program.

(3) Upon the completion of our initial business combination, we will provide our public shareholders with the opportunity to redeem their public shares for cash equal to their pro rata share of the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of our initial business combination, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares, subject to the limitations described herein whereby redemptions cannot cause our net tangible assets to be less than $5,000,001 and any limitations (including, but not limited to, cash requirements) created by the terms of the proposed business combination.

(4) Actual share amount is prior to any forfeiture of founder shares by our sponsor and as adjusted amount assumes no exercise of the underwriters’ over-allotment option. Share amounts have been retroactively restated to reflect the issuance of 1,437,500 Class B ordinary shares in connection with a share capitalization in February 2021.

Management’s Discussion and Analysis of
Financial Condition and Results of Operations

Overview

We are a blank check company incorporated as a Cayman Islands exempted company and formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities. We have not selected any specific business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target. We intend to effectuate our initial business combination using cash from the proceeds of this offering and the sale of the private placement shares, our shares, debt or a combination of the foregoing.

The issuance of additional ordinary shares or preference shares in connection with a business combination to the owners of the target or other investors:

• may significantly dilute the equity interest of investors in this offering, which dilution would increase if the anti-dilution provisions in the Class B ordinary shares resulted in the issuance of Class A shares on a greater than one-to-one basis upon conversion of the Class B ordinary shares;

• may subordinate the rights of holders of our ordinary shares if preference shares are issued with rights senior to those afforded our ordinary shares;

• could cause a change in control if a substantial number of our ordinary shares are issued, which may affect, among other things, our ability to use our net operating loss carry forwards, if any, and could result in the resignation or removal of our present officers and directors;

• may have the effect of delaying or preventing a change of control of us by diluting the share ownership or voting rights of a person seeking to obtain control of us; and

• may adversely affect prevailing market prices for our Class A ordinary shares.

Similarly, if we issue debt securities or otherwise incur significant debt to bank or other lenders or the owners of a target, it could result in:

• default and foreclosure on our assets if our operating revenues after an initial business combination are insufficient to repay our debt obligations;

• our immediate payment of all principal and accrued interest, if any, if the debt security is payable on demand;

• our inability to obtain necessary additional financing if the debt security contains covenants restricting our ability to obtain such financing while the debt security is outstanding;

• our inability to pay dividends on our ordinary shares;

• using a substantial portion of our cash flow to pay principal and interest on our debt, which will reduce the funds available for dividends on our ordinary shares if declared, our ability to pay expenses, make capital expenditures and acquisitions and fund other general corporate purposes;

• limitations on our flexibility in planning for and reacting to changes in our business and in the industry in which we operate;

• increased vulnerability to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation;

Table of Contents

• limitations on our ability to borrow additional amounts for expenses, capital expenditures, acquisitions, debt service requirements and execution of our strategy; and

• other purposes and other disadvantages compared to our competitors who have less debt.

As indicated in the accompanying financial statements, at February 9, 2021, we had no cash and deferred offering costs of $120,000. Further, we expect to incur significant costs in the pursuit of our initial business combination. We cannot assure you that our plans to raise capital or to complete our initial business combination will be successful.

Results of Operations and Known Trends or Future Events

We have neither engaged in any operations nor generated any revenues to date. Our only activities since inception have been organizational activities and those necessary to prepare for this offering. Following this offering, we will not generate any operating revenues until after completion of our initial business combination. We will generate non-operating income in the form of interest income on cash and cash equivalents after this offering. There has been no significant change in our financial or trading position and no material adverse change has occurred since the date of our audited financial statements. After this offering, we expect to incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as expenses as we conduct due diligence on prospective business combination candidates. We expect our expenses to increase substantially after the closing of this offering.

Liquidity and Capital Resources

Our liquidity needs have been satisfied prior to completion of this offering through the payment of $25,000 of expenses on our behalf by our sponsor in exchange for the issuance of the founder shares and loans to us of up to $600,000 by our sponsor under an unsecured promissory note. To date, we have borrowed approximately $118,000 under the note. We estimate that the net proceeds from (i) the sale of the Class A ordinary shares in this offering, after deducting offering expenses of approximately $2,500,000, underwriting discounts and commissions of $6,000,000 ($6,900,000 if the underwriters’ over-allotment option is exercised in full) (excluding deferred underwriting discounts and commissions of $10,500,000 (or $12,075,000 if the underwriters’ over-allotment option is exercised in full)), and (ii) the sale of the private placement shares for a purchase price of approximately $9,500,000 (or approximately $10,400,000 if the over-allotment option is exercised in full), will be $301,000,000 (or $346,000,000 if the underwriters’ over-allotment option is exercised in full). Of this amount, $300,000,000 (or $345,000,000 if the underwriters’ over-allotment option is exercised in full) will be held in the trust account, which includes $10,500,000 (or $12,075,000 if the underwriters’ over-allotment option is exercised in full) of deferred underwriting discounts and commissions. The proceeds held in the trust account will be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations. We will disclose in each quarterly and annual report filed with the SEC prior to our initial business combination whether the proceeds deposited in the trust account are invested in U.S. government treasury obligations or money market funds or a combination thereof. The remaining approximately $1,000,000 will not be held in the trust account. In the event that our offering expenses exceed our estimate of $2,500,000, we may fund such excess with funds not to be held in the trust account. In such case, the amount of funds we intend to be held outside the trust account would decrease by a corresponding amount. Conversely, in the event that the offering expenses are less than our estimate of $2,500,000, the amount of funds we intend to be held outside the trust account would increase by a corresponding amount.

We intend to use substantially all of the funds held in the trust account, including any amounts representing interest earned on the trust account (less taxes payable and deferred underwriting discounts and commissions). We may withdraw interest to pay our taxes, if any. Our annual income tax obligations will depend on the amount of interest and other income earned on the amounts held in the trust account. Based on current interest rates, we expect that interest earned on the trust account will be sufficient to pay our taxes. To the extent that our shares or debt is used, in whole or in part, as consideration to complete our initial business combination, the remaining proceeds held in the trust account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

Table of Contents

After the closing of this offering, we will have available to us the approximately $1,000,000 of proceeds held outside the trust account. We will use these funds primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a business combination.

We do not believe we will need to raise additional funds following this offering in order to meet the expenditures required for operating our business prior to our initial business combination, after taking into account funds that we expect would be made available to us from loans from our sponsor, members of our management team or any of their affiliates. However, if our estimates of the costs of identifying a target business, undertaking in-depth due diligence and negotiating an initial business combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our initial business combination. In order to fund working capital deficiencies or finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete our initial business combination, we would repay such loaned amounts. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from our trust account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into shares of the post business combination entity at a price of $10.00 per share at the option of the lender. The shares would be identical to the private placement shares, including as to exercise price, exercisability and exercise period. The terms of such loans, if any, have not been determined and no written agreements exist with respect to such loans. Prior to the completion of our initial business combination, we do not expect to seek loans from parties other than our sponsor or an affiliate of our sponsor as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our trust account.

We expect our primary liquidity requirements during that period to include approximately $505,000 for legal, accounting, due diligence, travel and other expenses associated with any business combination; $100,000 for legal and accounting fees related to regulatory reporting requirements; $270,000 for office space, utilities and administrative and support services; $85,000 for NYSE continued listing fees; and $40,000 for general working capital to cover miscellaneous expenses.

These amounts are estimates and may differ materially from our actual expenses. In addition, we could use a portion of the funds not being placed in trust to pay commitment fees for financing, fees to consultants to assist us with our search for a target business or as a down payment or to fund a “no-shop” provision (a provision designed to keep target businesses from “shopping” around for transactions with other companies or investors on terms more favorable to such target businesses) with respect to a particular proposed business combination, although we do not have any current intention to do so. If we entered into an agreement where we paid for the right to receive exclusivity from a target business, the amount that would be used as a down payment or to fund a “no-shop” provision would be determined based on the terms of the specific business combination and the amount of our available funds at the time. Our forfeiture of such funds (whether as a result of our breach or otherwise) could result in our not having sufficient funds to continue searching for, or conducting due diligence with respect to, prospective target businesses.

Moreover, we may need to obtain additional financing to complete our business combination, either because the transaction requires more cash than is available from the proceeds held in our trust account or because we become obligated to redeem a significant number of our public shares upon completion of the business combination, in which case we may issue additional securities or incur debt in connection with such business combination. If we are unable to complete our initial business combination because we do not have sufficient funds available to us, we will be forced to cease operations and liquidate the trust account.

Controls and Procedures

We are not currently required to maintain an effective system of internal controls as defined by Section 404 of the Sarbanes-Oxley Act. We will be required to comply with the internal control requirements of the Sarbanes-Oxley Act for the fiscal year ending December 31, 2022. Only in the event that we are deemed to be a large accelerated filer or an accelerated filer would we be required to comply with the independent registered public accounting firm

Table of Contents

attestation requirement. Further, for as long as we remain an emerging growth company as defined in the JOBS Act, we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirement.

Prior to the closing of this offering, we have not completed an assessment, nor has our independent registered public accounting firm tested our systems, of our internal controls. We expect to assess the internal controls of our target business or businesses prior to the completion of our initial business combination and, if necessary, to implement and test additional controls as we may determine are necessary in order to state that we maintain an effective system of internal controls. A target business may not be in compliance with the provisions of the Sarbanes-Oxley Act regarding the adequacy of internal controls. Many small and mid-sized target businesses we may consider for our business combination may have internal controls that need improvement in areas such as:

• staffing for financial, accounting and external reporting areas, including segregation of duties;

• reconciliation of accounts;

• proper recording of expenses and liabilities in the period to which they relate;

• evidence of internal review and approval of accounting transactions;

• documentation of processes, assumptions and conclusions underlying significant estimates; and

• documentation of accounting policies and procedures.

Because it will take time, management involvement and perhaps outside resources to determine what internal control improvements are necessary for us to meet regulatory requirements and market expectations for our operation of a target business, we may incur significant expenses in meeting our public reporting responsibilities, particularly in the areas of designing, enhancing, or remediating internal and disclosure controls. Doing so effectively may also take longer than we expect, thus increasing our exposure to financial fraud or erroneous financing reporting.

Once our management’s report on internal controls is complete, we will retain our independent registered public accounting firm to audit and render an opinion on such report when required by Section 404. The independent registered public accounting firm may identify additional issues concerning a target business’s internal controls while performing their audit of internal control over financial reporting.

Quantitative and Qualitative Disclosures about Market Risk

The net proceeds of this offering and the sale of the private placement shares held in the trust account will be invested in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations. Due to the short-term nature of these investments, we believe there will be no associated material exposure to interest rate risk.

Related Party Transactions

In February 2021, 7,187,500 founder shares were issued to our sponsor in exchange for the payment of $25,000 expenses on our behalf, or approximately $0.003 per share. On February 18, 2021, we issued 1,437,500 Class B ordinary shares to our sponsor in connection with a share capitalization, resulting in our sponsor holding an aggregate of 8,625,000 founder shares. The number of founder shares issued was determined based on the expectation that such founder shares would represent 20% of the outstanding shares upon completion of this offering (excluding the private placement shares). The per share purchase price of the founder shares was determined by dividing the amount of cash contributed to the company by the aggregate number of founder shares issued. In connection with this offering, our sponsor will forfeit a total of 120,000 founder shares, and 40,000 founder shares will be issued to each of our independent directors, William J. Clinton, Juan J. Daboub and Mary Beth Mandanas, at their original purchase price.

Commencing on the date that our securities are first listed on the NYSE, we have agreed to pay Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, a total of $10,000 per month for office space, utilities, secretarial support and administrative services. Upon completion of our initial business combination or our liquidation, we will cease paying these monthly fees.

Our sponsor, officers and directors, or any of their respective affiliates, will be reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made to our sponsor, officers, directors or our or their affiliates and will determine which expenses and the amount of expenses that will be reimbursed. There is no cap or ceiling on the reimbursement of out-of-pocket expenses incurred by such persons in connection with activities on our behalf.

Prior to the consummation of this offering, our sponsor has agreed to loan us up to $600,000 to be used for a portion of the expenses of this offering. To date, we have borrowed approximately $118,000 under the note. These loans are non-interest bearing, unsecured and are due at the closing of this offering. The loan will be repaid upon the closing of this offering as part of the estimated $2,500,000 of offering expenses.

In addition, in order to finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete our initial business combination, we would repay such loaned amounts. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from our trust account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into shares of the post business combination entity at a price of $10.00 per share at the option of the lender. Such shares would be identical to the private placement shares. The terms of such loans by our officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. We do not expect to seek loans from parties other than our sponsor or an affiliate of our sponsor as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our trust account.

Tortoise has committed to purchase an aggregate of 950,000 private placement shares (or 1,040,000 private placement shares if the underwriters’ over-allotment option is exercised in full) at a price of $10.00 per share (approximately $9,500,000 in the aggregate, or approximately $10,400,000 in the aggregate if the underwriters’ over-allotment option is exercised in full) in a private placement that will occur simultaneously with the closing of this offering.

Pursuant to a registration rights agreement we will enter into with our initial shareholders and Tortoise on or prior to the closing of this offering, we will be required to register certain securities for sale under the Securities Act. These holders and holders of shares issued upon conversion of working capital loans, if any, are entitled under the registration rights agreement to make up to three demands that we offer securities held by them for sale under the Securities Act and to have the securities covered thereby registered for resale pursuant to Rule 415 under the Securities Act. In addition, these holders have certain “piggy-back” registration rights with respect to certain underwritten offerings we may conduct. We will bear the costs and expenses of registering these securities.

Off-Balance Sheet Arrangements; Commitments and Contractual Obligations; Quarterly Results

As of February 9, 2021, we did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K and did not have any commitments or contractual obligations. No unaudited quarterly operating data is included in this prospectus as we have not conducted any operations to date.

JOBS Act

The JOBS Act contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We will qualify as an “emerging growth company” and under the JOBS Act will be allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Table of Contents

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an independent registered public accounting firm’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the independent registered public accounting firm’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of this offering or until we are no longer an “emerging growth company,” whichever is earlier.

Proposed Business

Overview

We are a blank check company newly incorporated as a Cayman Islands exempted company for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities, which we refer to throughout this prospectus as our initial business combination. We have not selected any business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target. We intend to focus our search for a target business in the broad energy transition or sustainability arena targeting industries that require innovative solutions to decarbonize in order to meet critical emission reduction objectives. The Intergovernmental Panel on Climate Change estimates that limiting global warming to 1.5 degrees Celsius above pre-industrial temperatures will require annual investments of $1.6 – $3.8 trillion in the global supply-side energy system through 2050, with some climate scenarios requiring net-zero global emissions by 2050, resulting in the need for high-growth energy transition and technology solutions. In light of this and other developments fostering a sense of urgency and responsibility, as of February 2021, more than 1,000 companies worldwide are leading the zero-carbon transition by setting emissions reduction targets through the Science Based Targets initiative (SBTi). We believe our management team, together with the broader Tortoise Ecofin Platforms, which are affiliates of our sponsor, are well suited to identify opportunities that create a positive environmental impact, exhibit strong ESG attributes and have the potential to generate attractive risk-adjusted returns for our shareholders, although we may pursue a business combination opportunity in any business or industry.

Our management team and an affiliate of Tortoise co-founded Tortoise Acquisition I (NYSE: SHLL), a special purpose acquisition company that completed its initial public offering in March 2019, in which it sold 23,300,917 units, each consisting of one share of Class A common stock and one-half of one warrant, with each whole warrant entitling the holder thereof to purchase one share of Class A common stock, for an offering price of $10.00 per unit, generating aggregate proceeds of approximately $233 million. In October 2020, Tortoise Acquisition I consummated its initial business combination with Hyliion, a leader in electrified powertrain solutions for Class 8 commercial vehicles. The combined entity, Hyliion Holdings Corp., is listed on the NYSE under the ticker symbol “HYLN.”

Our management team and an affiliate of Tortoise co-founded Tortoise Acquisition II (NYSE: SNPR), a special purpose acquisition company that completed its initial public offering in September 2020, in which it sold 34,500,000 units, each consisting of one Class A ordinary share and one-fourth of one warrant, with each whole warrant entitling the holder thereof to purchase one Class A ordinary share, for an offering price of $10.00 per unit, generating aggregate proceeds of approximately $345 million. In February 2021, Tortoise Acquisition II announced its initial business combination with Volta, a leading owner-operator of public electric vehicle charging infrastructure. The combined entity, Volta Inc., is expected to be listed on the NYSE under the ticker symbol “VLTA.”

Business Strategy

Table of Contents

Chief Executive Officer oversaw the evaluation of hundreds of acquisitions and investments. As a Managing Director and Portfolio Manager at Tortoise Capital Advisors, L.L.C., Mr. Pang has evaluated and made numerous portfolio company investments across a broad platform of industry sectors and strategies. We believe the breadth of Tortoise’s and Messrs. Cubbage’s and Pang’s investment experience across multiple sub-sectors is a competitive advantage.

Business Combination Criteria

• will benefit from our team’s operating expertise, technical expertise, structuring expertise, extensive network, insight and capital markets expertise;

• have attractive opportunities to grow the business through organic growth projects and third-party acquisitions;

• will be well received by public investors and are expected to have good access to the public capital markets;

• are engaged in activities that are consistent with Tortoise’s and management’s view of macro trends; and

• are expected to generate attractive risk-adjusted returns for our shareholders.

Table of Contents

Initial Business Combination

The NYSE rules require that we must complete one or more business combinations having an aggregate fair market value of at least 80% of the net assets held in trust (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time of the agreement to enter into the initial business combination. Our board will make the determination as to the fair market value of a target business or businesses. If our board is not able to independently determine the fair market value of a target business or businesses, we will obtain an opinion from an independent investment banking firm that is a member of FINRA or an independent accounting firm with respect to the satisfaction of such criteria. While we consider it unlikely that our board will not be able to make an independent determination of the fair market value of a target business or businesses, it may be unable to do so if the board is less familiar or experienced with the target company’s business or there is a significant amount of uncertainty as to the value of the company’s assets or prospects.

We may, at our option, pursue a business combination opportunity jointly with one or more entities affiliated with Tortoise and/or one or more investors in funds or separate accounts managed by Tortoise, which we refer to as an “Affiliated Joint Acquisition.” Any such parties would co-invest only if (i) permitted by applicable regulatory and other legal limitations; (ii) we and Tortoise considered such a transaction to be mutually beneficial to us as well as the affiliated entity; and (iii) other business reasons exist to do so, such as the strategic merits of including such co-investors, the need for additional capital beyond the amount held in our trust account to fund the business combination transaction and/or the desire to obtain committed capital for closing the business combination transaction. An Affiliated Joint Acquisition may be effected through a co-investment with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the business combination by issuing to such parties a class of equity or equity-linked securities. We refer to this potential future issuance, or a similar issuance to other specified purchasers, as a “specified future issuance” throughout this prospectus. The amount and other terms and conditions of any such specified future issuance would be determined at the time thereof. We are not obligated to make any specified future issuance and may determine not to do so. This is not an offer for any specified future issuance. Pursuant to the anti-dilution provisions of our Class B ordinary shares, any such specified future issuance would result in an adjustment to the conversion ratio such that our initial shareholders and their permitted transferees, if any, would retain their aggregate percentage ownership at 20% of the sum of the total number of all ordinary shares outstanding upon completion of this offering plus all shares issued in the specified future issuance (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the business combination and the private placement shares), unless the holders of a majority of the then-outstanding Class B ordinary shares agreed to waive such adjustment with respect to the specified future issuance at the time thereof. We cannot determine at this time whether a majority of the holders of our Class B ordinary shares would then agree to so waive such adjustment to the conversion ratio. They may waive such adjustment due to (but not limited to) the following: (i) closing conditions which are part of the agreement for our initial business combination; (ii) negotiation with Class A shareholders on structuring an initial business combination; (iii) negotiation with parties providing financing which would trigger the anti-dilution provisions of the Class B ordinary shares; or (iv) as part of the Affiliated Joint Acquisition. If such adjustment is not waived, the specified future issuance would

Table of Contents

not reduce the percentage ownership of holders of our Class B ordinary shares, but would reduce the percentage ownership of holders of our Class A ordinary shares. If such adjustment is waived, the specified future issuance would reduce the percentage ownership of holders of both classes of our ordinary shares.

We anticipate structuring our initial business combination either (i) in such a way so that the post-transaction company in which our public shareholders own shares will own or acquire 100% of the equity interests or assets of the target business or businesses or (ii) in such a way so that the post-transaction company owns or acquires less than 100% of such interests or assets of the target business in order to meet certain objectives of the target management team or shareholders or for other reasons, including an Affiliated Joint Acquisition as described above. However, we will only complete a business combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise is not required to register as an investment company under the Investment Company Act. Even if the post-transaction company owns or acquires 50% or more of the voting securities of the target, our shareholders prior to the business combination may collectively own a minority interest in the post-transaction company, depending on valuations ascribed to the target and us in the business combination transaction. For example, we could pursue a transaction in which we issue a substantial number of new shares in exchange for all of the outstanding capital stock, shares or other equity interests of a target. In this case, we would acquire a 100% controlling interest in the target. However, as a result of the issuance of a substantial number of new shares, our shareholders immediately prior to our initial business combination could own less than a majority of our outstanding shares subsequent to our initial business combination. If less than 100% of the equity interests or assets of a target business or businesses are owned or acquired by the post-transaction company, the portion of such business or businesses that is owned or acquired is what will be valued for purposes of the 80% of net assets test. If the business combination involves more than one target business, the 80% of net assets test will be based on the aggregate value of all of the transactions, and we will treat the target businesses together as the initial business combination for purposes of a tender offer or for seeking shareholder approval, as applicable.

Our Business Combination Process

Table of Contents

Our sponsor, members of our management team or their affiliates may sponsor other special purpose acquisition companies similar to ours during the period in which we are seeking an initial business combination and our officers and directors may become an officer or director of any other special purpose acquisition company with a class of securities registered under the Exchange Act, even before we have entered into a letter of intent, agreement in principle or definitive agreement regarding our initial business combination. Any such companies may present additional conflicts of interest in pursuing an acquisition target, particularly in the event there is an overlap among the management teams. For more information, see the section entitled “Management — Conflicts of Interest.”

Our Management Team

Members of our management team are not obligated to devote any specific number of hours to our matters but they intend to devote as much of their time as they deem necessary to our affairs until we have completed our initial business combination. The amount of time that any members of our management team will devote in any time period will vary based on whether a target business has been selected for our initial business combination and the current stage of the business combination process.

Table of Contents

We believe our management team’s operating and transaction experience and relationships with companies will provide us with a substantial number of potential business combination targets. Over the course of their careers, the members of our management team have developed a broad network of contacts and corporate relationships around the world. This network has grown through the activities of our management team sourcing, acquiring and financing businesses, our management team’s relationships with sellers, financing sources and target management teams and the experience of our management team in executing transactions under varying economic and financial market conditions. See the section of this prospectus entitled “Management” for a more complete description of our management team’s experience.

Status as a Public Company

We believe our structure will make us an attractive business combination partner to target businesses. As an existing public company, we offer a target business an alternative to the traditional initial public offering through a merger or other business combination with us. In a business combination transaction with us, the owners of the target business may, for example, exchange their shares of stock, shares or other equity interests in the target business for our Class A ordinary shares (or shares of a new holding company) or for a combination of our Class A ordinary shares and cash, allowing us to tailor the consideration to the specific needs of the sellers. Although there are various costs and obligations associated with being a public company, we believe target businesses will find this method a more certain and cost effective method to becoming a public company than the typical initial public offering. The typical initial public offering process takes a significantly longer period of time than the typical business combination transaction process, and there are significant expenses in the initial public offering process, including underwriting discounts and commissions, that may not be present to the same extent in connection with a business combination with us.

Furthermore, once a proposed business combination is completed, the target business will have effectively become public, whereas an initial public offering is always subject to the underwriters’ ability to complete the offering, as well as general market conditions, which could delay or prevent the offering from occurring or could have negative valuation consequences. Once public, we believe the target business would then have greater access to capital, an additional means of providing management incentives consistent with shareholders’ interests and the ability to use its equity as currency for acquisitions. Being a public company can offer further benefits by augmenting a company’s profile among potential new customers and vendors and aid in attracting talented employees.

While we believe that our structure and our management team’s backgrounds will make us an attractive business partner, some potential target businesses may view our status as a blank check company, such as our lack of an operating history and our ability to seek shareholder approval of any proposed initial business combination, negatively.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act. As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. If some investors find our securities less attractive as a result, there may be a less active trading market for our securities and the prices of our securities may be more volatile.

Financial Position

With funds available for a business combination initially in the amount of up to $289,500,000, after payment of $10,500,000 of deferred underwriting discounts and commissions (or up to $322,925,000 after payment of $12,075,000 of deferred underwriting discounts and commissions if the underwriters’ over-allotment option is exercised in full), in each case before fees and expenses associated with our initial business combination, we offer a target business a variety of options such as creating a liquidity event for its owners, providing capital for the potential growth and expansion of its operations or strengthening its balance sheet by reducing its debt or leverage ratio. Because we are able to complete our business combination using our cash, debt or equity securities, or a combination of the foregoing, we have the flexibility to use the most efficient combination that will allow us to tailor the consideration to be paid to the target business to fit its needs and desires. However, we have not taken any steps to secure third-party financing and there can be no assurance it will be available to us.

Effecting our Initial Business Combination

We are not presently engaged in, and we will not engage in, any operations for an indefinite period of time following this offering. We intend to effectuate our initial business combination using cash from the proceeds of this offering and the sale of the private placement shares, our shares, debt or a combination of the foregoing. We may seek to complete our initial business combination with a company or business that may be financially unstable or in its early stages of development or growth, which would subject us to the numerous risks inherent in such companies and businesses.

If our initial business combination is paid for using equity or debt securities, or not all of the funds released from the trust account are used for payment of the consideration in connection with our business combination or used for redemptions of purchases of our Class A ordinary shares, we may apply the balance of the cash released to us from the trust account for general corporate purposes, including for maintenance or expansion of operations of the post-transaction company, the payment of principal or interest due on indebtedness incurred in completing our initial business combination, to fund the purchase of other companies or for working capital.

We have not selected any business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions with any business combination target. Additionally, we have not engaged or retained any agent or other representative to identify or locate any suitable acquisition candidate, to conduct any research or take any measures, directly or indirectly, to locate or contact a target business, other than our officers and directors. Accordingly, there is no current basis for investors in this offering to evaluate the possible merits or risks of the target business with which we may ultimately complete our initial business combination. Although our management will assess the risks inherent in a particular target business with which we may combine, we cannot assure you that this assessment will result in our identifying all risks that a target business may encounter. Furthermore, some of those risks may be outside of our control, meaning that we can do nothing to control or reduce the chances that those risks will adversely affect a target business.

Table of Contents

We may need to obtain additional financing to complete our initial business combination, either because the transaction requires more cash than is available from the proceeds held in our trust account or because we become obligated to redeem a significant number of our public shares upon completion of the business combination, in which case we may issue additional securities or incur debt in connection with such business combination. In the case of an initial business combination funded with assets other than the trust account assets, our tender offer documents or proxy materials disclosing the business combination would disclose the terms of the financing and, only if required by applicable law, we would seek shareholder approval of such financing. There are no prohibitions on our ability to issue securities or incur debt in connection with our initial business combination. We are not currently a party to any arrangement or understanding with any third party with respect to raising any additional funds through the sale of securities, the incurrence of debt or otherwise.

Sources of Target Businesses

We anticipate that target business candidates will be brought to our attention from various unaffiliated sources, including investment market participants, private equity groups, investment banking firms, consultants, accounting firms and large business enterprises. Target businesses may be brought to our attention by such unaffiliated sources as a result of being solicited by us through calls or mailings. These sources may also introduce us to target businesses in which they think we may be interested on an unsolicited basis, since many of these sources will have read this prospectus and know what types of businesses we are targeting. Our officers and directors, as well as their affiliates, may also bring to our attention target business candidates that they become aware of through their business contacts as a result of formal or informal inquiries or discussions they may have, as well as attending trade shows or conventions. In addition, we expect to receive a number of proprietary deal flow opportunities that would not otherwise necessarily be available to us as a result of the track record and business relationships of our officers and directors. While we do not presently anticipate engaging the services of professional firms or other individuals that specialize in business acquisitions on any formal basis, we may engage these firms or other individuals in the future, in which event we may pay a finder’s fee, consulting fee or other compensation to be determined in an arm’s length negotiation based on the terms of the transaction. We will engage a finder only to the extent our management determines that the use of a finder may bring opportunities to us that may not otherwise be available to us or if finders approach us on an unsolicited basis with a potential transaction that our management determines is in our best interest to pursue. Payment of a finder’s fee is customarily tied to completion of a transaction, in which case any such fee will be paid out of the funds held in the trust account. In no event, however, will our sponsor or any of our existing officers or directors, or any entity with which they are affiliated, be paid any finder’s fee, consulting fee or other compensation by the company prior to, or for any services they render in order to effectuate, the completion of our initial business combination (regardless of the type of transaction that it is). We have agreed to pay Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, a total of $10,000 per month for office space, utilities, secretarial support and administrative services and to reimburse our sponsor for any out-of-pocket expenses related to identifying, investigating and completing an initial business combination. Some of our officers and directors may enter into employment or consulting agreements with the post-transaction company following our initial business combination. The presence or absence of any such fees or arrangements will not be used as a criterion in our selection process of an acquisition candidate.

We are not prohibited from pursuing an initial business combination with a business combination target that is affiliated with our sponsor, officers or directors, or from making the acquisition through a joint venture or other form of shared ownership with our sponsor, officers or directors. In the event we seek to complete our initial business combination with a business combination target that is affiliated with our sponsor, officers or directors, we, or a committee of independent directors, would obtain an opinion from an independent investment banking firm which is a member of FINRA or an independent accounting firm that such an initial business combination is fair to our company from a financial point of view. We are not required to obtain such an opinion in any other context.

As more fully discussed in the section of this prospectus entitled “Management — Conflicts of Interest,” if any of our officers or directors becomes aware of a business combination opportunity that falls within the line of business of any entity to which he or she has then-current fiduciary or contractual obligations, he or she may be required to present such business combination opportunity to such entity prior to presenting such business

Table of Contents

combination opportunity to us. Our officers and directors currently have certain relevant fiduciary duties or contractual obligations that may take priority over their duties to us. We may pursue an Affiliated Joint Acquisition opportunity with an entity to which an officer or director has a fiduciary or contractual obligation. Any such entity may co-invest with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the acquisition by issuing to such entity a class of equity or equity-linked securities. See “Management — Conflicts of Interest.”

Selection of a Target Business and Structuring of our Initial Business Combination

The NYSE rules require that our initial business combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the net assets held in trust (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time of the agreement to enter into the initial business combination. The fair market value of the target or targets will be determined by our board of directors based upon one or more standards generally accepted by the financial community, such as discounted cash flow valuation or value of comparable businesses. If our board is not able to independently determine the fair market value of the target business or businesses, we will obtain an opinion from an independent investment banking firm that is a member of FINRA or from an independent accounting firm with respect to the satisfaction of such criteria. We do not intend to purchase multiple businesses in unrelated industries in conjunction with our initial business combination. Subject to this requirement, our management will have virtually unrestricted flexibility in identifying and selecting one or more prospective target businesses, although we will not be permitted to effectuate our initial business combination with another blank check company or a similar company with nominal operations.

In any case, we will only complete an initial business combination in which we own or acquire 50% or more of the outstanding voting securities of the target or otherwise acquire an interest in the target sufficient for the post-transaction company not to be required to register as an investment company under the Investment Company Act. If we own or acquire less than 100% of the equity interests or assets of a target business or businesses, the portion of such business or businesses that are owned or acquired by the post-transaction company is what will be valued for purposes of the NYSE’s 80% of net assets test. There is no basis for investors in this offering to evaluate the possible merits or risks of any target business with which we may ultimately complete our business combination.

To the extent we effect our business combination with a company or business that may be financially unstable or in its early stages of development or growth, we may be affected by numerous risks inherent in such company or business. Although our management will endeavor to evaluate the risks inherent in a particular target business, we cannot assure you that we will properly ascertain or assess all significant risk factors.

In evaluating a prospective target business, we expect to conduct a thorough due diligence review, which may encompass, among other things, meetings with incumbent management and employees, document reviews, interviews of customers and suppliers, inspection of facilities, as applicable, as well as a review of financial, operational, legal and other information which will be made available to us. If we determine to move forward with a particular target, we will proceed to structure and negotiate the terms of the business combination transaction.

The time required to select and evaluate a target business and to structure and complete our initial business combination, and the costs associated with this process, are not currently ascertainable with any degree of certainty. Any costs incurred with respect to the identification and evaluation of, and negotiation with, a prospective target business with which our business combination is not ultimately completed will result in our incurring losses and will reduce the funds we can use to complete another business combination. The company will not pay any consulting fees to members of our management team, or any of their respective affiliates, for services rendered to or in connection with our initial business combination.

Lack of Business Diversification

For an indefinite period of time after the completion of our initial business combination, the prospects for our success may depend entirely on the future performance of a single business. Unlike other entities that have the resources to complete business combinations with multiple entities in one or several industries, it is probable that we

Table of Contents

will not have the resources to diversify our operations and mitigate the risks of being in a single line of business. In addition, we intend to focus our search for an initial business combination in a single industry. By completing our business combination with only a single entity, our lack of diversification may:

• subject us to negative economic, competitive and regulatory developments, any or all of which may have a substantial adverse impact on the particular industry in which we operate after our initial business combination, and

• cause us to depend on the marketing and sale of a single product or limited number of products or services.

Limited Ability to Evaluate the Target’s Management Team

Although we intend to closely scrutinize the management of a prospective target business when evaluating the desirability of effecting our business combination with that business, our assessment of the target business’s management may not prove to be correct. In addition, the future management may not have the necessary skills, qualifications or abilities to manage a public company. Furthermore, the future role of members of our management team, if any, in the target business cannot presently be stated with any certainty. The determination as to whether any of the members of our management team will remain with the combined company will be made at the time of our initial business combination. While it is possible that one or more of our directors will remain associated in some capacity with us following our business combination, it is unlikely that any of them will devote their full efforts to our affairs subsequent to our business combination. Moreover, we cannot assure you that members of our management team will have significant experience or knowledge relating to the operations of the particular target business.

We cannot assure you that any of our key personnel will remain in senior management or advisory positions with the combined company. The determination as to whether any of our key personnel will remain with the combined company will be made at the time of our initial business combination.

Following a business combination, we may seek to recruit additional managers to supplement the incumbent management of the target business. We cannot assure you that we will have the ability to recruit additional managers, or that additional managers will have the requisite skills, knowledge or experience necessary to enhance the incumbent management.

Shareholders May Not Have the Ability to Approve our Initial Business Combination

We may conduct redemptions without a shareholder vote pursuant to the tender offer rules of the SEC, subject to the provisions of our amended and restated memorandum and articles of association. However, we will seek shareholder approval if it is required by law or applicable stock exchange rule, or we may decide to seek shareholder approval for business or other legal reasons. Under the NYSE’s listing rules, shareholder approval would be required for our initial business combination if, for example:

• we issue Class A ordinary shares that will be equal to or in excess of 20% of the number of our Class A ordinary shares then outstanding (other than in a public offering);

• any of our directors, officers or substantial shareholders (as defined by the NYSE rules) has a 5% or greater interest, directly or indirectly, in the target business or assets to be acquired and if the number of ordinary shares to be issued, or if the number of ordinary shares into which the securities may be convertible or exercisable, exceeds either (a) 1% of the number of ordinary shares or 1% of the voting power outstanding before the issuance in the case of any of our directors or officers, or (b) 5% of the number of ordinary shares or 5% of the voting power outstanding before the issuance in the case of any substantial shareholders; or

• the issuance or potential issuance of ordinary shares will result in our undergoing a change of control.

Table of Contents

Permitted Purchases of our Securities

In the event we seek shareholder approval of our business combination and we do not conduct redemptions in connection with our business combination pursuant to the tender offer rules, our sponsor, directors, officers, advisors or their affiliates may purchase shares in privately negotiated transactions or in the open market either prior to or following the completion of our initial business combination. There is no limit on the number of shares our sponsor, directors, officers, advisors or their affiliates may purchase in such transactions, subject to compliance with applicable law and the rules of the NYSE. However, they have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions. None of the funds in the trust account will be used to purchase shares in such transactions. If they engage in such transactions, they will not make any such purchases when they are in possession of any material non-public information not disclosed to the seller or if such purchases are prohibited by Regulation M under the Exchange Act. Such a purchase may include a contractual acknowledgement that such shareholder, although still the record holder of our shares is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights.

The purpose of any such purchases of shares could be to (i) vote such shares in favor of the business combination and thereby increase the likelihood of obtaining shareholder approval of the business combination or (ii) to satisfy a closing condition in an agreement with a target that requires us to have a minimum net worth or a certain amount of cash at the closing of our business combination, where it appears that such requirement would otherwise not be met. Any such purchases of our securities may result in the completion of our business combination that may not otherwise have been possible.

In addition, if such purchases are made, the public “float” of our ordinary shares may be reduced and the number of beneficial holders of our securities may be reduced, which may make it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange.

Our sponsor, officers, directors and/or their affiliates anticipate that they may identify the shareholders with whom our sponsor, officers, directors or their affiliates may pursue privately negotiated purchases by either the shareholders contacting us directly or by our receipt of redemption requests submitted by shareholders (in the class of Class A ordinary shares) following our mailing of proxy materials in connection with our initial business combination. To the extent that our sponsor, officers, directors, advisors or their affiliates enter into a private purchase, they would identify and contact only potential selling shareholders who have expressed their election to redeem their shares for a pro rata share of the trust account or vote against our initial business combination, whether or not such shareholder has already submitted a proxy with respect to our initial business combination but only if such shares have not already been voted at the general meeting related to our initial business combination. Our sponsor, officers, directors, advisors or any of their affiliates will select which shareholders to purchase shares from based on the negotiated price and number of shares and any other factors that they may deem relevant, and will only purchase shares if such purchases comply with Regulation M under the Exchange Act and the other federal securities laws.

Any purchases by our sponsor, officers, directors and/or their affiliates who are affiliated purchasers under Rule 10b-18 under the Exchange Act will only be made to the extent such purchases are able to be made in compliance with Rule 10b-18, which is a safe harbor from liability for manipulation under Section 9(a)(2) and Rule 10b-5 of the Exchange Act. Rule 10b-18 has certain technical requirements that must be complied with in order for the safe harbor to be available to the purchaser. Our sponsor, officers, directors and/or their affiliates will not make purchases of ordinary shares if the purchases would violate Section 9(a)(2) or Rule 10b-5 of the Exchange Act. Any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent such purchasers are subject to such reporting requirements.

Redemption Rights for Public Shareholders upon Completion of our Initial Business Combination

We will provide our public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of the initial business combination including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the trust account is initially anticipated to be approximately $10.00 per public share. The per-share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting discounts and commissions we will pay to the underwriters. Tortoise and our sponsor, officers and directors will not be entitled to redemption rights with respect to any founder shares held by them or any private placement shares or public shares they acquire during or after this offering in connection with the completion of our business combination.

Limitations on Redemptions

Our amended and restated memorandum and articles of association will provide that in no event will we redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (so that we are not subject to the SEC’s “penny stock” rules). However, the proposed business combination may require (i) cash consideration to be paid to the target or its owners, (ii) cash to be transferred to the target for working capital or other general corporate purposes or (iii) the retention of cash to satisfy other conditions in accordance with the terms of the proposed business combination. In the event the aggregate cash consideration we would be required to pay for all Class A ordinary shares that are validly submitted for redemption plus any amount required to satisfy cash conditions pursuant to the terms of the proposed business combination exceed the aggregate amount of cash available to us, we will not complete the business combination or redeem any shares, and all Class A ordinary shares submitted for redemption will be returned to the holders thereof.

Manner of Conducting Redemptions

We will provide our public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares upon the completion of our initial business combination either (i) in connection with a general meeting called to approve the business combination or (ii) by means of a tender offer. The decision as to whether we will seek shareholder approval of a proposed business combination or conduct a tender offer will be made by us, solely in our discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require us to seek shareholder approval under applicable law or stock exchange listing requirement. Asset acquisitions and share purchases would not typically require shareholder approval while direct mergers with our company where we do not survive and any transactions where we issue more than 20% of our outstanding ordinary shares or seek to amend our amended and restated memorandum and articles of association would require shareholder approval. If we structure a business combination transaction with a target business in a manner that requires shareholder approval, we will not have discretion as to whether to seek a shareholder vote to approve the proposed business combination. We currently intend to conduct redemptions in connection with a shareholder vote unless shareholder approval is not required by applicable law or stock exchange listing requirement and we choose to conduct redemptions pursuant to the tender offer rules of the SEC for business or other legal reasons.

If we hold a shareholder vote to approve our initial business combination, we will, pursuant to our amended and restated memorandum and articles of association:

• conduct the redemptions in conjunction with a proxy solicitation pursuant to Regulation 14A of the Exchange Act, which regulates the solicitation of proxies, and not pursuant to the tender offer rules, and

• file proxy materials with the SEC.

In the event that we seek shareholder approval of our initial business combination, we will distribute proxy materials and, in connection therewith, provide our public shareholders with the redemption rights described above upon completion of the initial business combination.

Table of Contents

If we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association. A quorum for such meeting will consist of the holders present in person or by proxy of shares of the company representing a majority of the voting power of all outstanding shares of the company entitled to vote at such meeting. Our initial shareholders will count toward this quorum and have agreed to vote their founder shares and any public shares purchased during or after this offering in favor of our initial business combination. For purposes of seeking approval of the majority of our outstanding ordinary shares voted, abstentions and non-votes will have no effect on the approval of our initial business combination once a quorum is obtained. As a result, in addition to our initial shareholders’ founder shares and the private placement shares, we would need (i) 10,775,001, or 35.9% (assuming all outstanding shares are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), or (ii) 1,162,501, or 3.9% (assuming only the minimum number of shares representing a quorum are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), of the 30,000,000 public shares sold in this offering to be voted in favor of an initial business combination in order to have our initial business combination approved, subject to any higher consent threshold as may be required by Cayman Islands or other applicable law. We intend to give approximately 30 days (but not less than 10 days nor more than 60 days) prior written notice of any such meeting, if required, at which a vote shall be taken to approve our initial business combination. These quorum and voting thresholds, and the voting agreements of our initial shareholders, may make it more likely that we will consummate our initial business combination. Each public shareholder may elect to redeem its public shares irrespective of whether it votes for or against the proposed transaction. In addition, Tortoise and our sponsor, officers and directors will not be entitled to redemption rights with respect to any founder shares, private placement shares or public shares held by them in connection with the completion of a business combination.

If we conduct redemptions pursuant to the tender offer rules of the SEC, we will, pursuant to our amended and restated memorandum and articles of association:

• conduct the redemptions pursuant to Rule 13e-4 and Regulation 14E of the Exchange Act, which regulate issuer tender offers, and

• file tender offer documents with the SEC prior to completing our initial business combination which contain substantially the same financial and other information about the initial business combination and the redemption rights as is required under Regulation 14A of the Exchange Act, which regulates the solicitation of proxies. Although we are not required to do so, we currently intend to comply with the substantive and procedural requirements of Regulation 14A in connection with any shareholder vote even if we are not able to maintain our NYSE listing or Exchange Act registration.

Upon the public announcement of our business combination, we or our sponsor will terminate any plan established in accordance with Rule 10b5-1 to purchase our Class A ordinary shares in the open market if we elect to redeem our public shares through a tender offer, to comply with Rule 14e-5 under the Exchange Act.

Limitation on Redemption upon Completion of our Initial Business Combination if we Seek Shareholder Approval

If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our business combination pursuant to the tender offer rules, our amended and restated memorandum and articles of association will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13

Table of Contents

of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 20% of the shares sold in this offering, which we refer to as the “Excess Shares.” We believe this restriction will discourage shareholders from accumulating large blocks of shares, and subsequent attempts by such holders to use their ability to exercise their redemption rights against a proposed business combination as a means to force us or our management to purchase their shares at a significant premium to the then-current market price or on other undesirable terms. Absent this provision, a public shareholder holding more than an aggregate of 20% of the shares sold in this offering could threaten to exercise its redemption rights if such holder’s shares are not purchased by us, our sponsor or our management at a premium to the then-current market price or on other undesirable terms. By limiting our shareholders’ ability to redeem no more than 20% of the shares sold in this offering without our prior consent, we believe we will limit the ability of a small group of shareholders to unreasonably attempt to block our ability to complete our business combination, particularly in connection with a business combination with a target that requires as a closing condition that we have a minimum net worth or a certain amount of cash. However, we would not be restricting our shareholders’ ability to vote all of their shares (including Excess Shares) for or against our business combination.

Tendering Share Certificates in Connection with a Tender Offer or Redemption Rights

Public shareholders seeking to exercise their redemption rights, whether they are record holders or hold their shares in “street name,” will be required to either tender their certificates to our transfer agent prior to the date set forth in the proxy solicitation or tender offer materials (as applicable) mailed to such holders, or up to two business days prior to the initially scheduled vote on the proposal to approve the business combination in the event we distribute proxy materials, or to deliver their shares to the transfer agent electronically using the Depository Trust Company’s DWAC (Deposit/Withdrawal At Custodian) System, at the holder’s option. The proxy solicitation or tender offer materials (as applicable) that we will furnish to holders of our public shares in connection with our initial business combination will indicate the applicable delivery requirements. Accordingly, a public shareholder would have from the time we send out our tender offer materials until the close of the tender offer period, or up to two days prior to the initially scheduled vote on the business combination if we distribute proxy materials, as applicable, to tender its shares if it wishes to seek to exercise its redemption rights. Given the relatively short period in which to exercise redemption rights, it is advisable for shareholders to use electronic delivery of their public shares.

There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC System. The transfer agent will typically charge the tendering broker a fee of approximately $80.00 and it would be up to the broker whether or not to pass this cost on to the redeeming holder. However, this fee would be incurred regardless of whether or not we require holders seeking to exercise redemption rights to tender their shares. The need to deliver shares is a requirement of exercising redemption rights regardless of the timing of when such delivery must be effectuated.

The foregoing is different from the procedures used by many blank check companies. In order to perfect redemption rights in connection with their business combinations, many blank check companies would distribute proxy materials for the shareholders’ vote on an initial business combination, and a holder could simply vote against a proposed business combination and check a box on the proxy card indicating such holder was seeking to exercise his or her redemption rights. After the business combination was approved, the company would contact such shareholder to arrange for him or her to deliver his or her certificate to verify ownership. As a result, the shareholder then had an “option window” after the completion of the business combination during which he or she could monitor the price of the company’s shares in the market. If the price rose above the redemption price, he or she could sell his or her shares in the open market before actually delivering his or her shares to the company for cancellation. As a result, the redemption rights, to which shareholders were aware they needed to commit before the general meeting, would become “option” rights surviving past the completion of the business combination until the redeeming holder delivered its certificate. The requirement for physical or electronic delivery prior to the meeting ensures that a redeeming holder’s election to redeem is irrevocable once the business combination is approved.

Any request to redeem such shares, once made, may be withdrawn at any time up to the date set forth in the tender offer materials or the date of the general meeting set forth in our proxy materials, as applicable. Furthermore, if a holder of a public share delivered its certificate in connection with an election of redemption rights and subsequently decides prior to the applicable date not to elect to exercise such rights, such holder may simply

request that the transfer agent return the certificate (physically or electronically). It is anticipated that the funds to be distributed to holders of our public shares electing to redeem their shares will be distributed promptly after the completion of our business combination.

If our initial business combination is not approved or completed for any reason, then our public shareholders who elected to exercise their redemption rights would not be entitled to redeem their shares for the applicable pro rata share of the trust account. In such case, we will promptly return any certificates delivered by public holders who elected to redeem their shares.

If our initial proposed business combination is not completed, we may continue to try to complete a business combination with a different target until 24 months (or 27 months, as applicable) from the closing of this offering.

Redemption of Public Shares and Liquidation if no Initial Business Combination

Our amended and restated memorandum and articles of association will provide that we will have only 24 months (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering) from the closing of this offering to complete our initial business combination. If we are unable to complete our initial business combination within such 24-month period (or 27-month period as applicable) we will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

Tortoise and our sponsor, officers and directors will not be entitled to rights to liquidating distributions from the trust account with respect to any founder shares or private placement shares held by them if we fail to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering. However, if our sponsor, officers or directors acquire public shares in or after this offering, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our initial business combination within the allotted 24-month time period (or 27-month time period, as applicable).

Our sponsor, officers, directors and director nominees have agreed, pursuant to a written agreement with us, that they will not propose any amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, unless we provide our public shareholders with the opportunity to redeem their Class A ordinary shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares. However, we may not redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions (so that we are not subject to the SEC’s “penny stock” rules). If this optional redemption right is exercised with respect to an excessive number of public shares such that we cannot satisfy the net tangible asset requirement, we would not proceed with the amendment or the related redemption of our public shares at such time. Pursuant to our amended and restated memorandum and articles of association, such an amendment would need to be approved by the affirmative vote of the holders of at least two-thirds of all then outstanding ordinary shares who attend and vote in a general meeting.

We expect that all costs and expenses associated with implementing our plan of dissolution, as well as payments to any creditors, will be funded from amounts remaining out of the approximately $1,000,000 of proceeds held outside the trust account, although we cannot assure you that there will be sufficient funds for such purpose. However, if those funds are not sufficient to cover the costs and expenses associated with implementing our plan

Table of Contents

of dissolution, to the extent that there is any interest accrued in the trust account not required to pay our taxes on interest income earned on the trust account balance, we may request the trustee to release to us an additional amount of up to $100,000 of such accrued interest to pay those costs and expenses.

If we were to expend all of the net proceeds of this offering and the sale of the private placement shares, other than the proceeds deposited in the trust account, and without taking into account interest, if any, earned on the trust account, the per-share redemption amount received by shareholders upon our dissolution would be approximately $10.00. The proceeds deposited in the trust account could, however, become subject to the claims of our creditors which would have higher priority than the claims of our public shareholders. We cannot assure you that the actual per-share redemption amount received by shareholders will not be substantially less than $10.00. While we intend to pay such amounts, if any, we cannot assure you that we will have funds sufficient to pay or provide for all creditors’ claims.

Although we will seek to have all vendors, service providers (other than our independent registered public accounting firm), prospective target businesses and other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the trust account for the benefit of our public shareholders, there is no guarantee that they will execute such agreements or even if they execute such agreements that they would be prevented from bringing claims against the trust account including but not limited to fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain an advantage with respect to a claim against our assets, including the funds held in the trust account. If any third party refuses to execute an agreement waiving such claims to the monies held in the trust account, our management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to us than any alternative. Examples of possible instances where we may engage a third party that refuses to execute a waiver include the engagement of a third-party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with us and will not seek recourse against the trust account for any reason. Our sponsor has agreed that it will be liable to us if and to the extent any claims by a third party (other than our independent public accountants) for services rendered or products sold to us, or a prospective target business with which we have entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the trust account to below (i) $10.00 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay our taxes, except as to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the trust account (whether or not such waiver is enforceable) and except as to any claims under our indemnity of the underwriters of this offering against certain liabilities, including liabilities under the Securities Act. However, we have not asked our sponsor to reserve for such indemnification obligations, nor have we independently verified whether our sponsor has sufficient funds to satisfy its indemnity obligations, and we believe that our sponsor’s only assets are securities of our company. Therefore, we cannot assure you that our sponsor would be able to satisfy those obligations. As a result, if any such claims were successfully made against the trust account, the funds available for our initial business combination and redemptions could be reduced to less than $10.00 per public share. In such event, we may not be able to complete our initial business combination, and you would receive such lesser amount per share in connection with any redemption of your public shares. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

In the event that the proceeds in the trust account are reduced below (i) $10.00 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay our taxes, and our sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to

Table of Contents

take legal action against our sponsor to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against our sponsor to enforce its indemnification obligations to us, it is possible that our independent directors in exercising their business judgment may choose not to do so if, for example, the cost of such legal action is deemed by the independent directors to be too high relative to the amount recoverable or if the independent directors determine that a favorable outcome is not likely. We have not asked our sponsor to reserve for such indemnification obligations and we cannot assure you that our sponsor would be able to satisfy those obligations. Accordingly, we cannot assure you that due to claims of creditors the actual value of the per-share redemption price will not be less than $10.00 per public share.

We will seek to reduce the possibility that our sponsor will have to indemnify the trust account due to claims of creditors by endeavoring to have all vendors, service providers (other than our independent registered public accounting firm), prospective target businesses or other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to monies held in the trust account. Our sponsor will also not be liable as to any claims under our indemnity of the underwriters of this offering against certain liabilities, including liabilities under the Securities Act. We will have access to up to approximately $1,000,000 from the proceeds of this offering with which to pay any such potential claims (including costs and expenses incurred in connection with our liquidation, currently estimated to be no more than approximately $100,000). In the event that we liquidate and it is subsequently determined that the reserve for claims and liabilities is insufficient, shareholders who received funds from our trust account could be liable for claims made by creditors. In the event that our offering expenses exceed our estimate of $2,500,000, we may fund such excess with funds from the funds not to be held in the trust account. In such case, the amount of funds we intend to be held outside the trust account would decrease by a corresponding amount. Conversely, in the event that the offering expenses are less than our estimate of $2,500,000, the amount of funds we intend to be held outside the trust account would increase by a corresponding amount.

If we file a winding up petition or a winding up petition is filed against us that is not dismissed, the proceeds held in the trust account could be subject to applicable insolvency law, and a liquidator may determine that such funds should be included in our insolvency estate and subject to the claims of third-party creditors with priority over the claims of our shareholders. To the extent any bankruptcy or insolvency claims deplete the trust account, we cannot assure you we will be able to return $10.00 per share to our public shareholders. Additionally, if we file a winding up petition or a winding up petition is filed against us that is not dismissed, any distributions received by shareholders could be subject to challenge under applicable debtor/creditor and/or insolvency laws as a “voidable preference.” As a result, a liquidator could seek to recover some or all amounts received by our shareholders. Furthermore, our board of directors may be viewed as having breached its fiduciary duty to our creditors and/or may have acted in bad faith, and thereby exposing itself and our company to claims of punitive damages, by paying public shareholders from the trust account prior to addressing the claims of creditors. We cannot assure you that claims will not be brought against us for these reasons.

Our public shareholders will be entitled to receive funds from the trust account only (i) in the event of the redemption of our public shares if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law, (ii) in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering or (iii) if they redeem their respective shares for cash upon the completion of the initial business combination. In no other circumstances will a shareholder have any right or interest of any kind to or in the trust account. In the event we seek shareholder approval in connection with our initial business combination, a shareholder’s voting in connection with the business combination alone will not result in such shareholder redeeming its shares to us for an applicable pro rata share of the trust account. Such shareholder must have also exercised its redemption rights described above. These provisions of our amended and restated memorandum and articles of association, like all provisions of our amended and restated memorandum and articles of association, may be amended with a shareholder vote.

Comparison of Redemption or Purchase Prices in Connection with our Initial Business Combination and if We Fail to Complete our Initial Business Combination.

The following table compares the redemptions and other permitted purchases of public shares that may take place in connection with the completion of our initial business combination and if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering.

		Redemptions in Connection with our Initial Business Combination		Other Permitted Purchases of Public Shares by us or our Affiliates		Redemptions if we fail to Complete an Initial Business Combination
Calculation of redemption price		Redemptions at the time of our initial business combination may be made pursuant to a tender offer or in connection with a shareholder vote. The redemption price will be the same whether we conduct redemptions pursuant to a tender offer or in connection with a shareholder vote. In either case, our public shareholders may redeem their public shares for cash equal to the aggregate amount then on deposit in the trust account as of two business days prior to the consummation of the initial business combination (which is initially anticipated to be $10.00 per public share), including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares, subject to the limitation that no redemptions will take place, if all of the redemptions would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions and any limitations (including but not limited to cash requirements) agreed to in connection with the negotiation of terms of a proposed business combination.		If we seek shareholder approval of our initial business combination, our sponsor, directors, officers, advisors or their affiliates may purchase shares in privately negotiated transactions or in the open market prior to or following completion of our initial business combination. There is no limit to the prices that our sponsor, directors, officers, advisors or their affiliates may pay in these transactions.		If we are unable to complete our initial business combination within 24 months from the closing of this offering (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering), we will redeem all public shares at a per-share price, payable in cash, equal to the aggregate amount, then on deposit in the trust account (which is initially anticipated to be $10.00 per public share including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses)), divided by the number of then outstanding public shares.

Impact to remaining shareholders		The redemptions in connection with our initial business combination will reduce the book value per share for our remaining shareholders, who will bear the burden of the deferred underwriting discounts and commissions and interest withdrawn in order to pay our taxes (to the extent not paid from amounts accrued as interest on the funds held in the trust account).		If the permitted purchases described above are made there would be no impact to our remaining shareholders because the purchase price would not be paid by us.		The redemption of our public shares if we fail to complete our business combination will reduce the book value per share for the shares held by our initial shareholders, who will be our only remaining shareholders after such redemptions.

Comparison of This Offering to Those of Blank Check Companies Subject to Rule 419

The following table compares the terms of this offering to the terms of an offering by a blank check company subject to the provisions of Rule 419. This comparison assumes that the gross proceeds, underwriting discounts and commissions and underwriting expenses of our offering would be identical to those of an offering undertaken by a company subject to Rule 419, and that the underwriters will not exercise their over-allotment option. None of the provisions of Rule 419 apply to our offering.

	Terms of Our Offering	Terms Under a Rule 419 Offering
Escrow of offering proceeds	The rules of the NYSE provide that at least 90% of the gross proceeds from this offering and the private placement be deposited in a U.S.-based trust account. $300,000,000 of the net proceeds of this offering and the sale of the private placement shares will be deposited into a U.S.-based trust account at J.P. Morgan Chase Bank, N.A., with Continental Stock Transfer & Trust Company acting as trustee.	Approximately $255,150,000 of the offering proceeds would be deposited into either an escrow account with an insured depositary institution or in a separate bank account established by a broker-dealer in which the broker-dealer acts as trustee for persons having the beneficial interests in the account.
Investment of net proceeds	$300,000,000 of the net offering proceeds and the sale of the private placement shares held in trust will be invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations.	Proceeds could be invested only in specified securities such as a money market fund meeting conditions of the Investment Company Act or in securities that are direct obligations of, or obligations guaranteed as to principal or interest by, the United States.
Receipt of interest on escrowed funds	Interest on proceeds from the trust account to be paid to shareholders is reduced by (i) any taxes paid or payable, and (ii) in the event of our liquidation for failure to complete our initial business combination within the allotted time, up to $100,000 of net interest that may be released to us should we have no or insufficient working capital to fund the costs and expenses of our dissolution and liquidation.	Interest on funds in escrow account would be held for the sole benefit of investors, unless and only after the funds held in escrow were released to us in connection with our completion of a business combination.

	Terms of Our Offering	Terms Under a Rule 419 Offering
Limitation on fair value or net assets of target business	The NYSE rules require that our initial business combination must occur with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in trust (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time of our signing a definitive agreement in connection with our initial business combination.	The fair value or net assets of a target business must represent at least 80% of the maximum offering proceeds.
Trading of securities issued	The Class A ordinary shares will begin trading on or promptly after the date of this prospectus. We will file the Current Report on Form 8-K promptly after the closing of this offering, which is anticipated to take place three business days from the date of this prospectus. If the over- allotment option is exercised following the initial filing of such Current Report on Form 8-K, a second or amended Current Report on Form 8-K will be filed to provide updated financial information to reflect the exercise of the over-allotment option.	No trading of the Class A ordinary shares would be permitted until the completion of a business combination. During this period, the securities would be held in the escrow or trust account.
Election to remain an investor	We will provide our public shareholders with the opportunity to redeem their public shares for cash equal to their pro rata share of the aggregate amount then on deposit in the trust account as of two business days prior to the consummation of our initial business combination, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, upon the completion of our initial business combination, subject to the limitations described herein. We may not be required by law to hold a shareholder vote. If we are not required by law and do not otherwise decide to hold a shareholder vote, we will, pursuant to our amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the SEC and file tender offer documents with the SEC which will contain substantially the same financial and other information about the initial business combination and the redemption rights as is required under the SEC’s proxy rules.	A prospectus containing information pertaining to the business combination required by the SEC would be sent to each investor. Each investor would be given the opportunity to notify the company in writing, within a period of no less than 20 business days and no more than 45 business days from the effective date of a post-effective amendment to the company’s registration statement, to decide if he, she or it elects to remain a shareholder of the company or require the return of his, her or its investment. If the company has not received the notification by the end of the 45th business day, funds and interest or dividends, if any, held in the trust or escrow account are automatically returned to the shareholder. Unless a sufficient number of investors elect to remain investors, all funds on deposit in the escrow account must be returned to all of the investors and none of the securities are issued.

	If, however, we hold a shareholder vote, we will, like many blank check companies, offer to redeem shares in conjunction with a proxy solicitation pursuant to the tender offer rules. Pursuant to the tender offer rules, the tender offer period will be not less than 20 business days and, in the case of a shareholder vote, a final proxy statement would be mailed to public shareholders at least 10 days prior to the shareholder vote. However, we expect a draft proxy statement would be made available to such shareholder well in advance of such time, providing additional notice of redemption if we conduct redemptions in conjunction with a proxy solicitation. If we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association. Additionally, each public shareholder may elect to redeem their public shares irrespective of whether they vote for or against the proposed transaction. A quorum for such meeting will consist of the holders present in person or by proxy of shares of the company representing a majority of the voting power of all outstanding shares of the company entitled to vote at such meeting.
Business combination deadline	If we are unable to complete an initial business combination within 24 months from the closing of this offering (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering), we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the public shares,	If an acquisition has not been completed within 18 months after the effective date of the company’s registration statement, funds held in the trust or escrow account are returned to investors.

Release of funds	Except with respect to interest earned on the funds held in the trust account that may be released to us to pay our taxes, the proceeds from this offering held in the trust account will not be released from the trust account until the earliest of (i) the completion of our initial business combination (including the release of funds to pay any amounts due to any public shareholders who properly exercise their redemption rights in connection therewith), (ii) the redemption of any public shares properly submitted in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering and (iii) the redemption of our public shares if we are unable to complete our initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, subject to applicable law.	The proceeds held in the escrow account are not released until the earlier of the completion of a business combination or the failure to effect a business combination within the allotted time.

Limitation on redemption rights of shareholders holding more than 20% of the shares sold in this offering if we hold a shareholder vote	If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our amended and restated memorandum and articles of association will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to Excess Shares (more than an aggregate of 20% of the shares sold in this offering). Our public shareholders’ inability to redeem Excess Shares will reduce their influence over our ability to complete our initial business combination and they could suffer a material loss on their investment in us if they sell Excess Shares in open market transactions.	Most blank check companies provide no restrictions on the ability of shareholders to redeem shares based on the number of shares held by such shareholders in connection with an initial business combination.
Tendering share certificates in connection with a tender offer or redemption rights	We may require our public shareholders seeking to exercise their redemption rights, whether they are record holders or hold their shares in “street name,” to either tender their certificates to our transfer agent prior to the date set forth in the tender offer documents or proxy materials mailed to such holders or up to two business days prior to the initially scheduled vote on the proposal to approve the business combination in the event we distribute proxy materials, or to deliver their shares to the transfer agent electronically.	In order to perfect redemption rights in connection with their business combinations, holders could vote against a proposed business combination and check a box on the proxy card indicating such holders were seeking to exercise their redemption rights. After the business combination was approved, the company would contact such shareholders to arrange for them to deliver their certificate to verify ownership.

Competition

In identifying, evaluating and selecting a target business for our business combination, we may encounter intense competition from other entities having a business objective similar to ours, including other blank check companies, private equity groups and leveraged buyout funds, and operating businesses seeking strategic acquisitions. Many of these entities are well established and have extensive experience identifying and effecting business combinations directly or through affiliates. Moreover, many of these competitors possess greater financial, technical, human and other resources than we do. Our ability to acquire larger target businesses will be limited by our available financial resources. This inherent limitation gives others an advantage in pursuing the acquisition of a target business. Furthermore, our obligation to pay cash in connection with our public shareholders who exercise their redemption rights may reduce the resources available to us for our initial business combination, and the future dilution they potentially represent, may not be viewed favorably by certain target businesses. Either of these factors may place us at a competitive disadvantage in successfully negotiating an initial business combination.

Facilities

Our executive offices are located at 5100 W. 115th Place, Leawood, KS 66211, and our telephone number is (913) 981-1020. The cost for our use of this space is included in the $10,000 per month fee we will pay to Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, for office space, utilities, secretarial support and administrative services. We consider our current office space adequate for our current operations.

Employees

We currently have five officers. These individuals are not obligated to devote any specific number of hours to our matters but they intend to devote as much of their time as they deem necessary to our affairs until we have completed our initial business combination. The amount of time that they will devote in any time period will vary based on whether a target business has been selected for our initial business combination and the stage of the business combination process we are in.

Periodic Reporting and Financial Information

We have registered our Class A ordinary shares under the Exchange Act and have reporting obligations, including the requirement that we file annual, quarterly and current reports with the SEC. In accordance with the requirements of the Exchange Act, our annual reports will contain financial statements audited and reported on by our independent registered public accountants.

We will provide shareholders with audited financial statements of the prospective target business as part of the proxy solicitation or tender offer materials (as applicable) sent to shareholders. These financial statements may be required to be prepared in accordance with U.S. GAAP, or reconciled to, U.S. GAAP, or IFRS, depending on the circumstances, and the historical financial statements may be required to be audited in accordance with the standards of the PCAOB. These financial statement requirements may limit the pool of potential target businesses we may acquire because some targets may be unable to provide such statements in time for us to disclose such statements in accordance with federal proxy rules and complete our initial business combination within the prescribed time frame. We cannot assure you that any particular target business identified by us as a potential acquisition candidate will have financial statements prepared in accordance with the requirements outlined above, or that the potential target business will be able to prepare its financial statements in accordance with the requirements outlined above. To the extent that any applicable requirements cannot be met, we may not be able to acquire the proposed target business. While this may limit the pool of potential acquisition candidates, we do not believe that this limitation will be material.

We will be required to evaluate our internal control procedures for the fiscal year ending December 31, 2022 as required by the Sarbanes-Oxley Act. Only in the event we are deemed to be a large accelerated filer or an accelerated filer will we be required to have our internal control procedures audited. A target business may not be in compliance with the provisions of the Sarbanes-Oxley Act regarding adequacy of their internal controls. The development of the internal controls of any such entity to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete any such acquisition.

II and a member of its audit committee since the completion of its initial public offering in September 2020.

As Minister of Finance, Dr. Daboub helped to navigate his native country through several regional economic challenges including securing and sustaining El Salvador’s investment grade rating, “dollarizing” the economy and completing a Free Trade Agreement with the U.S. During this period, he also oversaw the emergency reconstruction of El Salvador after two major earthquakes in 2001. He held high government positions in El Salvador for 12 years from 1992 to 2004, working for three different administrations without belonging to any political party; including joining the Board of CEL, El Salvador’s electric utility, and serving as president of El Salvador’s electric distribution companies.

We believe Dr. Daboub’s significant international experience on market-based solutions to the effects of climate change, sustainability and governance, as well as, his leadership roles, both in the private and public sectors in operations and strategic planning matters brings important and valuable skills to our board of directors.

Number and Terms of Office of Officers and Directors

We intend to have 5 directors upon completion of this offering. Our board of directors will be divided into three classes with only one class of directors being elected in each year and each class (except for those directors appointed prior to our first annual general meeting) serving a three-year term. The term of office of the first class of directors, consisting of Stephen Pang, will expire at our first annual general meeting. The term of office of the second class of directors, consisting of Juan J. Daboub and William J. Clinton, will expire at the second annual general meeting. The term of office of the third class of directors, consisting of Vincent T. Cubbage and Mary Beth Mandanas, will expire at the third annual general meeting. We may not hold an annual general meeting until after we consummate our initial business combination.

Holders of our founder shares will have the right to appoint all of our directors prior to consummation of our initial business combination and holders of our public shares will not have the right to vote on the appointment or removal of directors during such time. These provisions of our amended and restated memorandum and articles of association may only be amended if approved by a majority of at least 90% of our ordinary shares voting at a general meeting.

Approval of our initial business combination will require the affirmative vote of a majority of our board of directors, which must include a majority of our independent directors and each of the non-independent directors nominated by our sponsor.

Our officers are appointed by the board of directors and serve at the discretion of the board of directors, rather than for specific terms of office. Our board of directors is authorized to appoint persons to the offices set forth in our amended and restated memorandum and articles of association as it deems appropriate. Our amended and restated memorandum and articles of association provide that our officers may consist of a Chairman of the Board, Chief Executive Officer, President, Chief Financial Officer, Vice Presidents, Secretary, Treasurer and such other offices as may be determined by the board of directors.

Director Independence

The NYSE listing standards require that a majority of our board of directors be independent. An “independent director” is defined generally as a person who has no material relationship with the listed company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the company). Our board of directors has determined that William J. Clinton, Juan J. Daboub and Mary Beth Mandanas are “independent directors” as defined in the NYSE listing standards and applicable SEC rules. Our independent directors will have regularly scheduled meetings at which only independent directors are present.

Officer and Director Compensation

None of our officers or directors have received any cash compensation for services rendered to us. Commencing on the date that our securities are first listed on the NYSE through the earlier of consummation of our initial business combination and our liquidation, we have agreed to pay Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, a total of $10,000 per month for office space, utilities, secretarial support and administrative services. In addition, our sponsor, executive officers and directors, or any of their respective affiliates, will be reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made to our sponsor, officers or directors, or our or their affiliates. Any such payments prior to an initial business combination will be made using funds held outside the trust account. Other than quarterly audit committee review of such reimbursements, we do not expect to have any additional controls in place governing our reimbursement payments to our directors and officers for their out-of-pocket expenses incurred in connection with our activities on our behalf in connection with identifying and consummating an initial business combination. Other than these payments and reimbursements, no compensation of any kind, including finder’s and consulting fees, will be paid by the company to our sponsor, officers and directors, or any of their respective affiliates, prior to completion of our initial business combination.

After the completion of our initial business combination, directors or members of our management team who remain with us may be paid consulting or management fees from the combined company. All of these fees will be fully disclosed to shareholders, to the extent then known, in the proxy solicitation or tender offer materials (as applicable) furnished to our shareholders in connection with a proposed business combination. We have not established any limit on the amount of such fees that may be paid by the combined company to our directors or members of management. It is unlikely the amount of such compensation will be known at the time of the proposed business combination, because the directors of the post-combination business will be responsible for determining officer and director compensation. Any compensation to be paid to our officers will be determined, or recommended to the board of directors for determination, either by a compensation committee constituted solely by independent directors or by a majority of the independent directors on our board of directors.

We do not intend to take any action to ensure that members of our management team maintain their positions with us after the consummation of our initial business combination, although it is possible that some or all of our officers and directors may negotiate employment or consulting arrangements to remain with us after our initial business combination. The existence or terms of any such employment or consulting arrangements to retain their positions with us may influence our management’s motivation in identifying or selecting a target business but we do not believe that the ability of our management to remain with us after the consummation of our initial business combination will be a determining factor in our decision to proceed with any potential business combination. We are not party to any agreements with our officers and directors that provide for benefits upon termination of employment.

Committees of the Board of Directors

Upon the effectiveness of the registration statement of which this prospectus forms a part, our board of directors will have three standing committees: an audit committee, a compensation committee and a nominating and corporate governance committee.

The charter of each committee will be available on our website.

Table of Contents

described below. William J. Clinton, Juan J. Daboub and Mary Beth Mandanas are independent. Because we expect to list our securities on the NYSE in connection with our initial public offering, we have one year from the date of this offering to have our audit committee be comprised solely of independent members.

Mary Beth Mandanas will serve as chair of the audit committee. Each member of the audit committee is financially literate and our board of directors has determined that Mary Beth Mandanas qualifies as an “audit committee financial expert” as defined in applicable SEC rules.

We will adopt an audit committee charter, which will detail the principal functions of the audit committee, including:

• the appointment, compensation, retention, replacement, and oversight of the work of the independent registered public accounting firm and any other independent registered public accounting firm engaged by us;

• pre-approving all audit and permitted non-audit services to be provided by the independent registered public accounting firm or any other registered public accounting firm engaged by us, and establishing pre-approval policies and procedures;

• setting clear hiring policies for employees or former employees of the independent registered public accounting firm;

• setting clear policies for audit partner rotation in compliance with applicable laws and regulations;

• obtaining and reviewing a report, at least annually, from the independent registered public accounting firm describing (i) the independent auditor’s internal quality-control procedures and (ii) any material issues raised by the most recent internal quality-control review, or peer review, of the audit firm, or by any inquiry or investigation by governmental or professional authorities within the preceding five years respecting one or more independent audits carried out by the firm and any steps taken to deal with such issues;

• reviewing and approving any related party transaction required to be disclosed pursuant to Item 404 of Regulation S-K promulgated by the SEC prior to us entering into such transaction; and

• reviewing with management, the independent registered public accounting firm, and our legal advisors, as appropriate, any legal, regulatory or compliance matters, including any correspondence with regulators or government agencies and any employee complaints or published reports that raise material issues regarding our financial statements or accounting policies and any significant changes in accounting standards or rules promulgated by the Financial Accounting Standards Board, the SEC or other regulatory authorities.

Compensation Committee

Prior to the consummation of this offering, we will establish a compensation committee of the board of directors. William J. Clinton, Juan J. Daboub and Mary Beth Mandanas will serve as members of our compensation committee. Under the NYSE listing standards and applicable SEC rules, we are required to have at least two members of the compensation committee, all of whom must be independent. William J. Clinton, Juan J. Daboub and Mary Beth Mandanas are independent. Juan J. Daboub will serve as chair of the compensation committee.

We will adopt a compensation committee charter, which will detail the principal functions of the compensation committee, including:

• reviewing and approving on an annual basis the corporate goals and objectives relevant to our chief executive officer’s compensation, evaluating our chief executive officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of our chief executive officer based on such evaluation;

110

Table of Contents

• reviewing and approving on an annual basis the compensation of all of our other officers;

• reviewing on an annual basis our executive compensation policies and plans;

• implementing and administering our incentive compensation equity-based remuneration plans;

• assisting management in complying with our proxy statement and annual report disclosure requirements;

• approving all special perquisites, special cash payments and other special compensation and benefit arrangements for our officers and employees;

• if required, producing a report on executive compensation to be included in our annual proxy statement; and

• reviewing, evaluating and recommending changes, if appropriate, to the remuneration for directors.

The charter will also provide that the compensation committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the compensation committee will consider the independence of each such adviser, including the factors required by the NYSE and the SEC.

Nominating and Corporate Governance Committee

Prior to the consummation of this offering, we will establish a nominating and corporate governance committee of the board of directors. The members of our nominating and corporate governance committee will be William J. Clinton, Juan J. Daboub and Mary Beth Mandanas. William J. Clinton will serve as chair of the nominating and corporate governance committee.

The primary purposes of our nominating and corporate governance committee will be to assist the board in:

• identifying, screening and reviewing individuals qualified to serve as directors and recommending to the board of directors candidates for nomination for election at the annual general meeting or to fill vacancies on the board of directors;

• developing, recommending to the board of directors and overseeing implementation of our corporate governance guidelines;

• coordinating and overseeing the annual self-evaluation of the board of directors, its committees, individual directors and management in the governance of the company; and

• reviewing on a regular basis our overall corporate governance and recommending improvements as and when necessary.

The nominating and corporate governance committee will be governed by a charter that complies with the rules of the NYSE.

Director Nominations

Our nominating and corporate governance committee will recommend to the board of directors candidates for nomination for election at the annual general meeting of the shareholders. The board of directors will also consider director candidates recommended for nomination by our shareholders during such times as they are seeking proposed nominees to stand for election at the next annual general meeting (or, if applicable, an extraordinary general meeting). Our shareholders that wish to nominate a director for appointment to our board of directors should follow the procedures set forth in our amended and restated memorandum and articles of association.

We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, our board of directors considers educational background, diversity of professional experience, knowledge of our business,

111

Table of Contents

integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of our shareholders. Prior to our initial business combination, holders of our public shares will not have the right to recommend director candidates for nomination to our board of directors.

Compensation Committee Interlocks and Insider Participation

None of our officers currently serves, or in the past year has served, as a member of the board of directors or compensation committee of any entity that has one or more officers serving on our board of directors.

Code of Ethics

Upon the effectiveness of the registration statement of which this prospectus forms a part, we will have adopted a Code of Ethics applicable to our directors, officers and employees. You will be able to review this document on our website. In addition, a copy of the Code of Ethics will be provided without charge upon request from us. We intend to disclose any amendments to or waivers of certain provisions of our Code of Ethics in a Current Report on Form 8-K.

Corporate Governance Guidelines

Our board of directors will adopt corporate governance guidelines in accordance with the corporate governance rules of the NYSE that serve as a flexible framework within which our board of directors and its committees operate. These guidelines will cover a number of areas including board membership criteria and director qualifications, director responsibilities, board agenda, roles of the chairman of the board, chief executive officer and presiding director, meetings of independent directors, committee responsibilities and assignments, board member access to management and independent advisors, director communications with third parties, director compensation, director orientation and continuing education, evaluation of senior management and management succession planning. A copy of our corporate governance guidelines will be posted on our website.

Conflicts of Interest

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;

• directors should not improperly fetter the exercise of future discretion;

• duty to exercise authority for the purpose for which it is conferred;

• 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 at the expense of the company. 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 amended and restated memorandum and articles of association or alternatively by shareholder approval at general meetings.

Tortoise manages several investment vehicles. Tortoise and its affiliates may compete with us for acquisition opportunities. If these entities or companies decide to pursue any such opportunity, we may be precluded from pursuing such opportunities. In addition, investment ideas generated within Tortoise may be suitable for both us and for current or future Tortoise Funds and may be directed to such affiliates rather than to us. Neither Tortoise nor

112

Table of Contents

members of our management team who are also employed by Tortoise have any obligation to present us with any opportunity for a potential business combination of which they become aware. Tortoise and/or our management, in their capacities as partners, officers or employees of Tortoise or in their other endeavors, may be required to present potential business combinations to the related entities described above, current or future affiliates of Tortoise, or third parties, before they present such opportunities to us.

Additionally, our sponsor and certain of our officers and directors are, and may in the future become, affiliated with entities that are engaged in a similar business. For example, certain of our officers and directors currently serve in similar roles for Tortoise Acquisition II, a blank check company incorporated as a Cayman Islands exempted company and formed for the purpose of effecting its own initial business combination. Mr. Cubbage is the President, Chief Executive Officer and Chairman of the Board of directors of Tortoise Acquisition II, Mr. Pang is the Chief Financial Officer and a director of Tortoise Acquisition II and Messrs. Brock, Zimmer and Schnitzer are, respectively, Vice President, Business Development, Vice President, Finance and Vice President, General Counsel and Secretary of Tortoise Acquisition II, and each such officer and director owes fiduciary duties under Cayman Islands law to Tortoise Acquisition II.

Notwithstanding the foregoing, we may pursue an Affiliated Joint Acquisition opportunity with any affiliates of Tortoise or the Tortoise Funds. Such entities may co-invest with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the acquisition by issuing to such entity a class of equity or equity-linked securities. Each of our officers and directors presently has, and any of them in the future may have additional fiduciary or contractual obligations to other entities pursuant to which such officer or director is or will be required to present a business combination opportunity to such entity. Accordingly, if any of our officers or directors becomes aware of a business combination opportunity which is suitable for an entity to which he or she has then-current fiduciary or contractual obligations, he or she will honor his or her fiduciary or contractual obligations to present such opportunity to such other entity. We do not believe, however, that the fiduciary duties or contractual obligations of our officers or directors will materially affect our ability to complete our business combination. In addition, we may pursue an Affiliated Joint Acquisition opportunity with an entity to which an officer or director has a fiduciary or contractual obligation. Any such entity may co-invest with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the acquisition by issuing to such entity a class of equity or equity-linked securities. Our amended and restated memorandum and articles of association will provide that we renounce our interest in any corporate opportunity offered to any director or officer unless such opportunity is expressly offered to such person solely in his or her capacity as a director or officer of our company and such opportunity is one we are legally and contractually permitted to undertake and would otherwise be reasonable for us to pursue. See “Risk Factors — Certain of our officers and directors are now, and all of them may in the future become, affiliated with entities engaged in business activities similar to those intended to be conducted by us and, accordingly, may have conflicts of interest in allocating their time and determining to which entity a particular business opportunity should be presented.”

Our sponsor, members of our management team or their affiliates may sponsor other special purpose acquisition companies similar to ours during the period in which we are seeking an initial business combination and our officers and directors may become an officer or director of any other special purpose acquisition company with a class of securities registered under the Exchange Act, even before we have entered into a letter of intent, agreement in principle or definitive agreement regarding our initial business combination. Any such companies may present additional conflicts of interest in pursuing an acquisition target, particularly in the event there is an overlap among the management teams.

Potential investors should also be aware of the following other potential conflicts of interest:

• None of our officers or directors is required to commit his or her full time to our affairs and, accordingly, may have conflicts of interest in allocating his or her time among various business activities.

• In the course of their other business activities, our officers and directors may become aware of investment and business opportunities which may be appropriate for presentation to us as well as the other entities with which they are affiliated. Our management may have conflicts of interest in determining to which entity a particular business opportunity should be presented.

• Tortoise and our sponsor, officers and directors will not be entitled to redemption rights with respect to any founder shares, private placement shares or public shares held by them in connection with the consummation of our initial business combination. Additionally, Tortoise and our sponsor, officers and directors will not be entitled to rights to liquidating distributions with respect to any founder shares or private placement shares held by them if we fail to consummate our initial business combination within 24 months (or 27 months, as applicable) after the closing of this offering. If we do not complete our initial business combination within such applicable time period, the proceeds of the sale of the private placement shares held in the trust account will be used to fund the redemption of our public shares, and the private placement shares will be worthless. Furthermore, our initial shareholders have agreed not to transfer, assign or sell any founder shares held by them until one year after the date of the consummation of our initial business combination or earlier if, subsequent to our initial business combination, (i) the last sale price of our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination or (ii) we consummate a subsequent liquidation, merger, share exchange or other similar transaction which results in all of our shareholders having the right to exchange their ordinary shares for cash, securities or other property. With certain limited exceptions, the private placement shares will not be transferable, assignable or saleable until 30 days after the completion of our initial business combination. Since our sponsor and officers and directors may directly or indirectly own ordinary shares following this offering, our officers and directors may have a conflict of interest in determining whether a particular target business is an appropriate business with which to effectuate our initial business combination.

• Our officers and directors may have a conflict of interest with respect to evaluating a particular business combination if the retention or resignation of any such officers and directors was included by a target business as a condition to any agreement with respect to our initial business combination.

• Our sponsor, officers or directors may have a conflict of interest with respect to evaluating a business combination and financing arrangements as we may obtain loans from our sponsor or an affiliate of our sponsor or any of our officers or directors to finance transaction costs in connection with an intended initial business combination. Up to $1,500,000 of such loans may be convertible into shares at a price of $10.00 per share at the option of the lender. Such shares would be identical to the private placement shares.

The conflicts described above may not be resolved in our favor.

We are not prohibited from pursuing an initial business combination with a company that is affiliated with our sponsor, officers or directors or making the acquisition through a joint venture or other form of shared ownership with our sponsor, officers or directors. In the event we seek to complete our initial business combination with a business combination target that is affiliated with our sponsor, officers or directors, we, or a committee of independent directors, would obtain an opinion from an independent investment banking firm which is a member of FINRA or from an independent accounting firm that such initial business combination is fair to our company from a financial point of view. We are not required to obtain such an opinion in any other context. Furthermore, in no event will our sponsor or any of our existing officers or directors, or any of their respective affiliates, be paid by the company any finder’s fee, consulting fee or other compensation prior to, or for any services they render in order to effectuate, the completion of our initial business combination. Further, commencing on the date our securities are first listed on the NYSE, we will pay an amount equal to $10,000 per month to Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, for office space, utilities, secretarial support and administrative services provided to us.

We cannot assure you that any of the above mentioned conflicts will be resolved in our favor.

In the event that we submit our initial business combination to our public shareholders for a vote, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association. Tortoise and our sponsor and each member of our management team have agreed to vote any founder shares and private placement shares held by them and any public shares purchased during or after this offering in favor of our initial business combination.

Limitation on Liability and Indemnification of Officers and Directors

Cayman Islands law does not limit the extent to which a company’s memorandum and 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 amended and restated memorandum and articles of association will provide that our officers and directors will be indemnified by us to the fullest extent permitted by law, as it now exists or may in the future be amended, including for any liability incurred in their capacities as such, except through their own actual fraud, willful default or willful neglect. We expect to purchase a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

Our officers and directors have agreed, and any persons who may become officers or directors prior to the initial business combination will agree, to waive any right, title, interest or claim of any kind in or to any monies in the trust account, and to waive any right, title, interest or claim of any kind they may have in the future as a result of, or arising out of, any services provided to us and will not seek recourse against the trust account for any reason whatsoever. Accordingly, any indemnification provided will only be able to be satisfied by us if (i) we have sufficient funds outside of the trust account or (ii) we consummate an initial business combination.

Our indemnification obligations may discourage shareholders from bringing a lawsuit against our officers or directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against our officers and directors, even though such an action, if successful, might otherwise benefit us and our shareholders. Furthermore, a shareholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against our officers and directors pursuant to these indemnification provisions.

We believe that these provisions, the insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling us pursuant to 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.

Table of Contents

Immediately after this offering, our initial shareholders will beneficially own 20% of the then-issued and outstanding ordinary shares (excluding the private placement shares and assuming they do not purchase any shares in this offering). If we increase or decrease the size of the offering, we will effect a share dividend or a share contribution back to capital, or other appropriate mechanism, as applicable, with respect to our Class B ordinary shares immediately prior to the consummation of the offering in such amounts to maintain the number of founder shares at 20% of our issued and outstanding ordinary shares upon the consummation of this offering. Because of this ownership block, our initial shareholders may be able to effectively influence the outcome of all matters requiring approval by our shareholders, including the appointment or removal of directors, amendments to our amended and restated memorandum and articles of association and approval of significant corporate transactions, including approval of our initial business combination. Pursuant to the terms of our amended and restated memorandum and articles of association, holders of our Class B ordinary shares have the exclusive right to elect, remove and replace any director prior to the consummation of our initial business combination. This provision may only be amended if approved by holders of 90% of our ordinary shares entitled to vote thereon.

The holders of the founder shares have agreed (A) to vote any shares owned by them in favor of any proposed business combination and (B) not to redeem any shares in connection with a shareholder vote to approve a proposed initial business combination.

Tortoise has committed, pursuant to a written agreement, to purchase an aggregate of 950,000 private placement shares (or 1,040,000 private placement shares if the underwriters’ over-allotment option is exercised in full), at a price of $10.00 per share (approximately $9,500,000 in the aggregate or approximately $10,400,000 in the aggregate if the underwriters’ over-allotment option is exercised in full), in a private placement that will close simultaneously with the closing of this offering. If we do not complete our initial business combination within 24 months from the closing of this offering (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering), the private placement shares will be worthless. The private placement shares are subject to the transfer restrictions described below. Otherwise, the private placement shares have terms and provisions that are identical to those of the Class A ordinary shares being sold in this offering.

Our sponsor, its affiliates and our officers and directors are deemed to be our “promoters” as such term is defined under the federal securities laws.

Transfers of Founder Shares and Private Placement Shares

The founder shares and private placement shares are each subject to transfer restrictions pursuant to a letter agreement to be entered into by Tortoise and our sponsor, directors and officers and us. This letter agreement will provide that the founder shares may not be transferred, assigned or sold until the earlier of (x) one year after the completion of our initial business combination or earlier if, subsequent to our business combination, the last sale price of our Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination, and (y) the date on which we complete a liquidation, merger, share exchange, reorganization or other similar transaction after our initial business combination that results in all of our shareholders having the right to exchange their ordinary shares for cash, securities or other property.

The letter agreement will provide that the private placement shares may not be transferred, assigned or sold until 30 days following the completion of our initial business combination.

Additionally, in the event of (i) our liquidation prior to the completion of our initial business combination or (ii) the completion of a liquidation, merger, share exchange or other similar transaction which results in all of our shareholders having the right to exchange their ordinary shares for cash, securities or other property subsequent to our completion of our initial business combination, the lock-up period shall terminate. However, in the case of clauses (a) through (f) below, such securities may be transferred during the lock-up period to certain permitted transferees, provided that they enter into a written agreement agreeing to be bound by these transfer restrictions.

118

Table of Contents

Permitted transfers include: (a) transfers to our officers or directors, any affiliates or family members of any of our officers or directors, any members of our sponsor or their affiliates, or any affiliates of our sponsor, (b) in the case of an individual, transfers by gift to members of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic relations order; (e) transfers by virtue of the laws of our sponsor’s operating agreement upon dissolution of our sponsor; and (f) transfers by private sales or transfers made in connection with the consummation of a business combination at prices no greater than the price at which the securities were originally purchased.

Permitted transferees would be subject to the same written agreements as our sponsor, directors and officers with respect to (i) voting any founder shares held by them in favor of the initial business combination, (ii) agreeing to not propose any amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of public shares if we do not complete an initial business combination within 24 months (or 27 months, as applicable) and (iii) waiving their redemption rights and rights to liquidating distributions.

Certain Relationships and Related Party Transactions

Tortoise has committed, pursuant to a written agreement, to purchase an aggregate of 950,000 (or 1,040,000 if the over-allotment option is exercised in full) private placement shares for a purchase price of $10.00 per share in a private placement that will occur simultaneously with the closing of this offering. As such, Tortoise’s interest in this transaction is valued at between approximately $9,500,000 and approximately $10,400,000 if the underwriters’ over-allotment option is exercised in full, depending on the number of private placement shares purchased. The private placement shares may not, subject to certain limited exceptions, be transferred, assigned or sold by the holder until 30 days after the completion of our initial business combination.

As more fully discussed in the section of this prospectus titled “Management — Conflicts of Interest,” if any of our officers or directors becomes aware of a business combination opportunity that falls within the line of business of any entity to which he or she has then-current fiduciary or contractual obligations, he or she will honor his or her fiduciary or contractual obligations to present such business combination opportunity to such entity. Our officers and directors currently have certain relevant fiduciary duties or contractual obligations that may take priority over their duties to us. We may pursue an Affiliated Joint Acquisition opportunity with an entity to which an officer or director has a fiduciary or contractual obligation. Any such entity may co-invest with us in the target business at the time of our initial business combination, or we could raise additional proceeds to complete the acquisition by issuing to such entity a class of equity or equity-linked securities. See “Management — Conflicts of Interest.”

Commencing on the date that our securities are first listed on the NYSE, we will pay Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, a total of $10,000 per month for office space, utilities, secretarial support and administrative services. Upon completion of our initial business combination or our liquidation, we will cease paying these monthly fees.

Other than these monthly fees, no compensation of any kind, including finder’s and consulting fees, will be paid by the company to our sponsor, officers and directors, or any of their respective affiliates, for services rendered prior to or in connection with the completion of an initial business combination. However, these individuals will be reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made to our sponsor, officers, directors or our or their affiliates and will determine which expenses and the amount of expenses that will be reimbursed. There is no cap or ceiling on the reimbursement of out-of-pocket expenses incurred by such persons in connection with activities on our behalf.

Prior to the closing of this offering, our sponsor may loan us up to $600,000 to be used for a portion of the expenses of this offering. To date, we have borrowed approximately $118,000 under the note. These loans would be non-interest bearing, unsecured and are due at the closing of this offering. The loan would be repaid upon the closing of this offering as part of the estimated $2,500,000 of offering expenses. The value of our sponsor’s interest in this transaction corresponds to the principal amount outstanding under any such loan.

120

Table of Contents

In addition, in order to finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete an initial business combination, we would repay such loaned amounts. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from our trust account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into shares at a price of $10.00 per share at the option of the lender. The shares would be identical to the private placement shares. Except as set forth above, the terms of such loans by our officers and directors, if any, have not been determined and no written agreements exist with respect to such loans. Prior to the completion of our initial business combination, we do not expect to seek loans from parties other than our sponsor or an affiliate of our sponsor as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our trust account.

After our initial business combination, members of our management team who remain with us may be paid consulting, management or other fees from the combined company with any and all amounts being fully disclosed to our shareholders, to the extent then known, in the tender offer or proxy solicitation materials (as applicable) furnished to our shareholders. It is unlikely the amount of such compensation will be known at the time of distribution of such tender offer materials or at the time of a general meeting held to consider our initial business combination, as applicable, as it will be up to the directors of the post-combination business to determine executive and director compensation.

We will enter into a registration rights agreement with respect to the private placement shares, the shares issuable upon conversion of working capital loans (if any) and the Class A ordinary shares issuable upon conversion of the founder shares, which is described under the heading “Description of Securities — Registration Rights.”

At our request, the underwriters have agreed to reserve up to 100,000 of the Class A ordinary shares offered by this prospectus for sale to certain members of Tortoise, at the initial public offering price. Sales in the Directed Shares Program will be made at our direction by Goldman Sachs & Co. LLC. The underwriters will receive the same underwriting discount on any shares purchased pursuant to this program as they will on any other shares sold to the public in this offering. We do not know if individual investors will choose to purchase all or any portion of these reserved Class A ordinary shares, but any purchases they do make will reduce the number of Class A ordinary shares available in the overall offering. Any reserved Class A ordinary shares not purchased in the Directed Shares Program will be offered by the underwriters to the general public on the same terms as the other Class A ordinary shares.

Related Party Policy

We have not yet adopted a formal policy for the review, approval or ratification of related party transactions. Accordingly, the transactions discussed above were not reviewed, approved or ratified in accordance with any such policy.

Prior to the consummation of this offering, we will adopt a code of ethics requiring us to avoid, wherever possible, all conflicts of interests, except under guidelines or resolutions approved by our board of directors (or the appropriate committee of our board) or as disclosed in our public filings with the SEC. Under our code of ethics, conflict of interest situations will include any financial transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) involving the company.

In addition, our audit committee, pursuant to a written charter that we will adopt prior to the consummation of this offering, will be responsible for reviewing and approving related party transactions to the extent that we enter into such transactions. An affirmative vote of a majority of the members of the audit committee present at a meeting at which a quorum is present will be required in order to approve a related party transaction. A majority of the members of the entire audit committee will constitute a quorum. Without a meeting, the unanimous written consent of all of the members of the audit committee will be required to approve a related party transaction. A form of the audit committee charter that we plan to adopt prior to the consummation of this offering is filed as an exhibit to the registration statement of which this prospectus is a part. We also require each of our directors and executive officers to complete a directors’ and officers’ questionnaire that elicits information about related party transactions.

121

Table of Contents

These procedures are intended to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the part of a director, employee or officer.

To further minimize conflicts of interest, we will not consummate an initial business combination with an entity that is affiliated with any of our sponsor, officers or directors unless we, or a committee of independent directors, have obtained an opinion from an independent investment banking firm which is a member of FINRA or an independent accounting firm that our initial business combination is fair to our company from a financial point of view. Furthermore, no finder’s fees, reimbursements or cash payments will be made to our sponsor, officers or directors, or our or their affiliates, for services rendered to us prior to or in connection with the completion of our initial business combination, other than the following payments, none of which will be made from the proceeds of this offering held in the trust account prior to the completion of our initial business combination:

• repayment of up to an aggregate of $600,000 in loans made to us by our sponsor to cover offering-related and organizational expenses;

• payment to Tortoise Capital Advisors, L.L.C., an affiliate of our sponsor, of $10,000 per month for office space, utilities, secretarial support and administrative services;

• reimbursement for any out-of-pocket expenses related to identifying, investigating and completing an initial business combination; and

• repayment of loans which may be made by our sponsor or an affiliate of our sponsor or certain of our officers and directors to finance transaction costs in connection with an intended initial business combination, the terms of which have not been determined nor have any written agreements been executed with respect thereto. Up to $1,500,000 of such loans may be convertible into shares, at a price of $10.00 per share at the option of the lender.

The foregoing payments will be made from the proceeds of the sale of private placement shares that will not be held in the trust account or from the funds available to us from interest earned on the trust account balance. Our audit committee will review on a quarterly basis all payments that were made to our sponsor, officers or directors, or our or their affiliates.

Description of Securities

We are a Cayman Islands exempted company and our affairs are governed by our amended and restated memorandum and articles of association, the Companies Act and the common law of the Cayman Islands. Pursuant to our amended and restated memorandum and articles of association, our authorized share capital consists of 200,000,000 Class A ordinary shares, $0.0001 par value each, 20,000,000 Class B ordinary shares, $0.0001 par value each, and 1,000,000 undesignated preference shares, $0.0001 par value each. The following description summarizes certain terms of our share capital as set out more particularly in our amended and restated memorandum and articles of association. Because it is only a summary, it may not contain all the information that is important to you.

Ordinary Shares

Upon the closing of this offering, 38,450,000 ordinary shares will be outstanding (assuming no exercise of the underwriters’ over-allotment option and the corresponding forfeiture of 1,125,000 founder shares by our sponsor), consisting of:

• 30,000,000 our Class A ordinary shares being offered in this offering;

• 950,000 private placement shares issued simultaneously with the closing of this offering; and

• 7,500,000 Class B ordinary shares held by our sponsor and independent directors.

If we increase or decrease the size of the offering, we will effect a share dividend or a share contribution back to capital or other appropriate mechanism, as applicable, with respect to our Class B ordinary shares immediately prior to the consummation of the offering in such amount as to maintain the number of founder shares at 20% of the issued and outstanding ordinary shares upon the consummation of this offering.

Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. Holders of our Class B ordinary shares will have the right to appoint all of our directors prior to our initial business combination. On any other matter submitted to a vote of our shareholders, holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of our shareholders except as required by law or stock exchange rule. Unless specified in our amended and restated memorandum and articles of association, or as required by applicable provisions of the Companies Act or applicable stock exchange rules, the affirmative vote of a majority of our ordinary shares that are voted is required to approve any such matter voted on by our shareholders. Approval of certain actions will require a special resolution under Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association; such actions include amending our amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. Our board of directors will be divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. There is no cumulative voting with respect to the appointment or removal of directors, with the result that the holders of more than 50% of the shares voted for the appointment or removal of directors can appoint all of the directors. Our shareholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor. Pursuant to the terms of our amended and restated memorandum and articles of association, holders of our Class B ordinary shares have the exclusive right to elect, remove and replace any director prior to the consummation of our initial business combination. In respect of any vote or votes to continue the company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction), which requires the approval of at least two-thirds of the votes of all ordinary shares, holders of our founder shares will have ten votes for every founder share and holders of our Class A ordinary shares will have one vote for every Class A ordinary share. This provision may only be amended if approved by holders of 90% of our ordinary shares entitled to vote thereon.

Because our amended and restated memorandum and articles of association authorizes the issuance of up to 200,000,000 Class A ordinary shares, if we were to enter into a business combination, we may (depending on the terms of such a business combination) be required to increase the number of Class A ordinary shares which we are authorized to issue at the same time as our shareholders vote on the business combination to the extent we seek shareholder approval in connection with our business combination.

123

Our board of directors is divided into three classes with only one class of directors being elected in each year and each class (except for those directors appointed prior to our first annual general meeting) serving a three-year term. In accordance with the NYSE corporate governance requirements, we are not required to hold an annual general meeting until no later than one year after our first fiscal year end following our listing on the NYSE. There is no requirement under the Companies Act for us to hold annual or general meetings or appoint directors. We may not hold an annual general meeting to appoint new directors prior to the consummation of our initial business combination.

We will provide our public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of our initial business combination including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares, subject to the limitations described herein. The amount in the trust account is initially anticipated to be approximately $10.00 per public share. The per-share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting discounts and commissions we will pay to the underwriters. Tortoise and our sponsor, officers and directors will not be entitled to redemption rights with respect to any founder shares, private placement shares or public shares held by them in connection with the completion of our business combination. Unlike many blank check companies that hold shareholder votes and conduct proxy solicitations in conjunction with their initial business combinations and provide for related redemptions of public shares for cash upon completion of such initial business combinations even when a vote is not required by law, if a shareholder vote is not required by law and we do not decide to hold a shareholder vote for business or other legal reasons, we will, pursuant to our amended and restated memorandum and articles of association, conduct the redemptions pursuant to the tender offer rules of the SEC, and file tender offer documents with the SEC prior to completing our initial business combination. Our amended and restated memorandum and articles of association will require these tender offer documents to contain substantially the same financial and other information about the initial business combination and the redemption rights as is required under the SEC’s proxy rules. If, however, shareholder approval of the transaction is required by law, or we decide to obtain shareholder approval for business or other legal reasons, we will, like many blank check companies, offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If we seek shareholder approval, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association. A quorum for such meeting will consist of the holders present in person or by proxy of shares of the company representing a majority of the voting power of all outstanding shares of the company entitled to vote at such meeting. However, the participation of our sponsor, officers, directors, advisors or their affiliates in privately-negotiated transactions (as described in this prospectus), if any, could result in the approval of our business combination even if a majority of our public shareholders vote, or indicate their intention to vote, against such business combination. For purposes of seeking approval of the majority of our outstanding ordinary shares voted, abstentions and non-votes will have no effect on the approval of our business combination once a quorum is obtained. We intend to give approximately 30 days (but not less than 10 days nor more than 60 days) prior written notice of any such meeting, if required, at which a vote shall be taken to approve our business combination. These quorum and voting thresholds, and the voting agreements of our initial shareholders, may make it more likely that we will consummate our initial business combination.

If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our business combination pursuant to the tender offer rules, our amended and restated memorandum and articles of association will provide that a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 20% of the ordinary shares sold in this offering, which we refer to as the Excess Shares. However, we would not be restricting our shareholders’ ability to vote all of their shares (including Excess Shares) for or against our business combination. Our shareholders’ inability to redeem the Excess Shares will reduce their influence over our ability to complete our business combination, and such shareholders could suffer a material loss in their investment if they sell such Excess Shares on the open market. Additionally, such shareholders will not receive redemption distributions with respect to the Excess Shares if we complete the business combination. And, as a result, such shareholders will continue to hold that number of shares exceeding 20% and, in order to dispose such shares would be required to sell their shares in open market transactions, potentially at a loss.

Table of Contents

If we seek shareholder approval in connection with our business combination, our initial shareholders have agreed to vote their founder shares and any public shares purchased during or after this offering in favor of our initial business combination. As a result, in addition to our initial shareholders’ founder shares and the private placement shares, we would need (i) 10,775,001, or 35.9% (assuming all outstanding shares are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), or (ii) 1,162,501, or 3.9% (assuming only the minimum number of shares representing a quorum are voted, the underwriters’ over-allotment option is not exercised and our sponsor, officers and directors do not purchase any public shares), of the 30,000,000 public shares sold in this offering to be voted in favor of an initial business combination in order to have our initial business combination approved, subject to any higher consent threshold as may be required by Cayman Islands or other applicable law. Additionally, each public shareholder may elect to redeem its public shares irrespective of whether it votes for or against the proposed transaction (subject to the limitation described in the preceding paragraph).

Pursuant to our amended and restated memorandum and articles of association, if we are unable to complete our initial business combination within 24 months from the closing of this offering (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering), we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter subject to lawfully available funds therefor, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. Tortoise and our sponsor, officers and directors will not be entitled to rights to liquidating distributions from the trust account with respect to any founder shares or private placement shares held by them if we fail to complete our business combination within 24 months (or 27 months, as applicable) from the closing of this offering. However, if our sponsor, officers or directors acquire public shares in or after this offering, they will be entitled to liquidating distributions from the trust account with respect to such public shares if we fail to complete our business combination within the prescribed time period.

In the event of a winding up, liquidation or dissolution of the company after a business combination, our shareholders are entitled to share ratably in all assets remaining available for distribution to them after payment of liabilities and after provision is made for each class of shares, if any, having preference over the ordinary shares. Our shareholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the ordinary shares, except that we will provide our public shareholders with the opportunity to redeem their public shares for cash equal to their pro rata share of the aggregate amount then on deposit in the trust account, upon the completion of our initial business combination, subject to the limitations described herein.

Private Placement Shares

The private placement shares will not be transferable, assignable or salable until 30 days after the completion of our initial business combination (except, among other limited exceptions as described under “Principal Shareholders — Transfers of Founder Shares and Private Placement Shares,” to our officers and directors and other persons or entities affiliated with Tortoise). Except as described below, the private placement shares have terms and provisions that are identical to those of the Class A ordinary shares being sold in this offering.

In order to finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete our initial business combination, we would repay such loaned amounts out of the proceeds of the trust account released to us. In the event that our initial business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from our trust account would be used to repay such loaned amounts. Up to $1,500,000 of such loans may be convertible into shares at a price of $10.00 per share at the option of the lender. Such shares would be identical to the private placement shares.

Table of Contents

Tortoise has agreed not to transfer, assign or sell any of the private placement shares until the date that is 30 days after the date we complete our initial business combination, except, among other limited exceptions as described under “Principal Shareholders — Transfers of Founder Shares and Private Placement Shares,” to our officers and directors and other persons or entities affiliated with Tortoise.

Founder Shares

The founder shares are designated as Class B ordinary shares and, except as described below, identical to the Class A ordinary shares being sold in this offering, and holders of founder shares have the same shareholder rights as public shareholders, except that (i) only holders of the founder shares have the right to vote on the appointment or removal of directors prior to our initial business combination, (ii) in respect of any vote or votes to continue the company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction), which requires the approval of at least two-thirds of the votes of all ordinary shares, holders of our founder shares will have ten votes for every founder share and holders of our Class A ordinary shares will have one vote for every Class A ordinary share, (iii) the founder shares are subject to certain transfer restrictions, as described in more detail below, (iv) Tortoise and our sponsor, officers and directors will not be entitled to (A) redemption rights with respect to any founder shares, private placement shares or public shares held by them in connection with the completion of our business combination, (B) redemption rights with respect to any founder shares, private placement shares or public shares held by them in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering or (C) rights to liquidating distributions from the trust account with respect to any founder shares or private placement shares held by them if we fail to complete our business combination within 24 months (or 27 months, as applicable) from the closing of this offering, although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our business combination within such time period, (v) the founder shares are our Class B ordinary shares that will automatically convert into our Class A ordinary shares at the time of our initial business combination on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights, as described herein and (vi) the founder shares are subject to registration rights. If we submit our business combination to our public shareholders for a vote, we will complete our initial business combination only if we obtain the approval of an ordinary resolution under Cayman Islands law, or such higher percentage as may be required by Cayman Islands law, and pursuant to our amended and restated memorandum and articles of association. Tortoise and our sponsor and each member of our management team have agreed to vote any founder shares and private placement shares held by them and any public shares purchased during or after this offering in favor of our initial business combination.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of our initial business combination on a one-for-one basis (subject to adjustment for share sub-divisions, share dividends, reorganizations, recapitalizations and the like), and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in this offering and related to the closing of the business combination, the ratio at which Class B ordinary shares shall convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all ordinary shares outstanding upon completion of this offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the business combination.

Our initial shareholders have agreed not to transfer, assign or sell any founder shares held by them until one year after the date of the consummation of our initial business combination or earlier if, subsequent to our business combination, (i) the last sale price of our ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination or (ii) we consummate a subsequent liquidation, merger, share exchange or other similar transaction that results in all of our shareholders having the right to exchange their ordinary shares for cash, securities or other property. Our sponsor (or its permitted transferees) will forfeit up to 1,125,000 founder shares depending on the exercise of the over-allotment option in order to maintain

126

Table of Contents

our initial shareholders’ ownership of 20% of our ordinary shares after this offering. The founder shares are identical to the ordinary shares being sold in this offering. However, the holders have agreed (A) to vote any shares owned by them in favor of any proposed business combination and (B) not to convert any shares in connection with a shareholder vote to approve a proposed initial business combination.

Under Cayman Islands law, we must keep a register of members and there will be entered therein:

• the names and addresses of the members, a statement of the shares held by each member, and of the amount paid or agreed to be considered as paid, on the shares of each member;

• the date on which the name of any person was entered on the register as a member; and

• the date on which any person ceased to be a member.

Under Cayman Islands law, the register of members of our company is prima facie evidence of the matters set out therein (i.e. the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a member registered in the register of members will be deemed as a matter of Cayman Islands law to have legal title to the shares as set against its name in the register of members. Upon the closing of this public offering, the register of members will be immediately updated to reflect the issue of shares by us. Once our register of members has been updated, the shareholders recorded in the register of members will be deemed to have legal title to the shares set against their name. However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. If an application for an order for rectification of the register of members were made in respect of our ordinary shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

Preference Shares

Our amended and restated memorandum and articles of association authorize 1,000,000 preference shares and will provide that preference shares may be issued from time to time in one or more series. Our board of directors will be authorized to fix the voting rights, if any, designations, powers, preferences, the relative, participating, optional or other special rights and any qualifications, limitations and restrictions thereof, applicable to the shares of each series. Our board of directors will be able to, without shareholder approval, issue preference shares with voting and other rights that could adversely affect the voting power and other rights of the holders of the ordinary shares and could have anti-takeover effects. The ability of our board of directors to issue preference shares without shareholder approval could have the effect of delaying, deferring or preventing a change of control of us or the removal of existing management. We have no preference shares issued and outstanding at the date hereof. Although we do not currently intend to issue any preference shares, we cannot assure you that we will not do so in the future. No preference shares are being issued or registered in this offering.

Dividends

We have not paid any cash dividends on our ordinary shares to date and do not intend to pay cash dividends prior to the completion of a business combination. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial conditions subsequent to completion of a business combination. The payment of any cash dividends subsequent to a business combination will be within the discretion of our board of directors at such time. On February 18, 2021, we issued 1,437,500 Class B ordinary shares to our sponsor in connection with a share capitalization, resulting in our sponsor holding an aggregate of 8,625,000 founder shares. Our board of directors is not currently contemplating and does not anticipate declaring any other share dividends in the foreseeable future. Further, if we incur any indebtedness, our ability to declare dividends may be limited by restrictive covenants we may agree to in connection therewith.

Our Transfer Agent

The transfer agent for our ordinary shares is Continental Stock Transfer & Trust Company. We have agreed to indemnify Continental Stock Transfer & Trust Company in its role as transfer agent, its agents and each of its shareholders, directors, officers and employees against all claims and losses that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence, willful misconduct or bad faith of the indemnified person or entity.

Continental Stock Transfer & Trust Company has agreed that it has no right of set-off or any right, title, interest or claim of any kind to, or to any monies in, the trust account, and has irrevocably waived any right, title, interest or claim of any kind to, or to any monies in, the trust account that it may have now or in the future. Accordingly, any indemnification provided will only be able to be satisfied, or a claim will only be able to be pursued, solely against us and our assets outside the trust account and not against any monies in the trust account or interest earned thereon.

Certain Differences in Corporate Law

We are incorporated in the Cayman Islands. Our management chose the Cayman Islands as our place of incorporation because:

• we believe investors are increasingly familiar with special purpose investment vehicles organized as Cayman Islands companies;

• we believe we will have added flexibility in our selection of an initial business combination as a Cayman Islands company because of its favorable tax system;

• of its political and economic stability;

• of its effective judicial system;

• of the absence of exchange control or currency restrictions; and

• of the availability of professional support services.

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.

General Meetings. The directors (by majority approval), the chief executive officer, or the chairman (as applicable) may, whenever they think fit, convene a general meeting of the company. In order for business to be transacted at any general meeting, a quorum of shareholders must be met. Pursuant to our amended and restated memorandum and articles of association, one or more shareholders holding at least a majority of the paid up voting share capital of the company present in person or by proxy and entitled to vote at that meeting shall form a quorum (the “Attending Shareholders”). At such general meeting, the Attending Shareholders may then pass resolutions either by ordinary resolution or special resolution (or by some other resolution threshold) as required by the Companies Act and our amended and restated memorandum and articles of association. For example, in the case of an ordinary resolution, an action can be passed by ordinary resolution at a general meeting with the affirmative vote in favor of the action by a simple majority of the total shares held by those that attend and vote at a meeting at which a quorum is present. By contrast, an action can be passed by special resolution at a general meeting with the affirmative vote of at least a two-thirds (2/3) majority (or such higher threshold as specified in the company’s amended and restated memorandum and articles of association) of the total shares held by those that attend and vote at a meeting at which a quorum is present.

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 is facilitated by the laws of that other jurisdiction).

128

Table of Contents

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 or merger or consolidation must then be authorized by either (a) a special resolution of the shareholders of each company; or (b) such other authorization, if any, as may be specified in such constituent company’s articles of association. No shareholder resolution is required for a merger between a parent company (i.e., a company that holds issued shares that together represent at least 90% of the votes at a general meeting of the subsidiary company) and its subsidiary company, if a copy of the plan of merger is given to every member of each subsidiary company to be merged 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 court waives such requirement. If the Cayman Islands Registrar of Companies is satisfied that the requirements of the Companies Act (which includes certain other formalities) have been complied with, the Registrar of Companies will register the plan of merger or consolidation.

Where the merger or consolidation involves a 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 any jurisdictions; (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; (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; and (v) that there is no other reason why it would be against the public interest to permit the merger or consolidation.

Where the surviving company is the Cayman Islands exempted company, 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 consolidated 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; and (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.

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 in certain circumstances if they follow a prescribed procedure. In essence, where such rights apply, that procedure is as follows: (a) the shareholder must give his 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 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 his 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 (b) above or 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) must file a petition with the Cayman Islands Grand Court 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

129

Table of Contents

company. At the hearing of that petition, the 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 to be contributed 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, schemes of arrangement will generally be more suited for complex mergers or other transactions involving widely held companies, commonly referred to in the Cayman Islands as a “scheme of arrangement” which 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 a majority in number of each class of shareholders and creditors with whom the arrangement is to be made and who must in addition represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meeting summoned for that purpose. The convening of the meetings and subsequently the terms of the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder would have the right to express to the court the view that the transaction should not be approved, the court can be expected to approve the arrangement if it satisfies itself that:

• we are not proposing to act illegally or beyond the scope of our 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 consider; 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 or takeover offer (as described below) is approved, 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 90% of the shares to whom the offer is made 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 Grand Court of the Cayman Islands, 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.

Shareholders’ Suits. Walkers, 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;

130

Table of Contents

• 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, 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, or to the extent they 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 company except for the exemptions and privileges listed below:

• annual reporting requirements are minimal and consist mainly of a statement that the company has conducted its operations mainly outside of the Cayman Islands and has complied with the provisions of the Companies Act;

• an exempted company’s register of members is not open to inspection and can be kept outside of the Cayman Islands;

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

• an exempted company may issue shares with no par value;

• 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 circumstance in which a court may be prepared to pierce or lift the corporate veil).

Our Amended and Restated Memorandum and Articles of Association

Our amended and restated memorandum and articles of association will contain certain requirements and restrictions relating to this offering that will apply to us until the completion of our initial business combination. These provisions (other than amendments relating to the appointment or removal of directors prior to our initial business combination, which require the approval of a majority of at least 90% of our ordinary shares voting at a general meeting) cannot be amended without a special resolution. As a matter of Cayman Islands law, a resolution is deemed to be a special resolution where it has been approved by either (i) at least two-thirds (or any higher threshold specified in a company’s articles of association) of a company’s shareholders entitled to vote in person or, where proxies are allowed, by proxy at a general meeting for which notice specifying the intention to propose the resolution as a special resolution has been given; or (ii) if so authorized by a company’s articles of association, by a unanimous written resolution of all of the company’s shareholders. Other than as described above, our amended and restated memorandum and articles of association provide that special resolutions must be approved either by at least two-thirds of the shares voted at a general meeting of the company (i.e., the lowest threshold permissible under Cayman Islands law), or by a unanimous written resolution of all of our shareholders.

Our initial shareholders, who will collectively beneficially own 20% of our ordinary shares upon the closing of this offering (excluding the private placement shares and assuming they do not purchase any shares in this offering), will participate in any vote to amend our amended and restated memorandum and articles of association and will have the discretion to vote in any manner they choose. Specifically, our amended and restated memorandum and articles of association provides, among other things, that:

• If we are unable to complete our initial business combination within 24 months from the closing of this offering (or 27 months from the closing of this offering if we have executed a letter of intent, agreement in principle or definitive agreement for an initial business combination within 24 months from the closing of this offering), we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account including interest earned on the funds held in the trust account and not previously released to us to pay our taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law;

• Prior to our initial business combination, we may not issue additional shares that would entitle the holders thereof to (i) receive funds from the trust account or (ii) vote on any initial business combination;

• Although we do not intend to enter into a business combination with a target business that is affiliated with our sponsor, our directors or our officers, we are not prohibited from doing so. In the event we enter into such a transaction, we, or a committee of independent directors, will obtain an opinion from an independent investment banking firm that is a member of FINRA or an independent accounting firm that such a business combination is fair to our company from a financial point of view;

• If a shareholder vote on our initial business combination is not required by law and we do not decide to hold a shareholder vote for business or other legal reasons, we will offer to redeem our public shares pursuant to Rule 13e-4 and Regulation 14E of the Exchange Act, and will file tender offer documents with the SEC prior to completing our initial business combination which contain substantially the same financial and other information about our initial business combination and the redemption rights as is required under Regulation 14A of the Exchange Act;

• The NYSE rules require that our initial business combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the net assets held in trust (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time of the agreement to enter into the initial business combination;

132

Table of Contents

• If our shareholders approve an amendment to our amended and restated memorandum and articles of association that would affect the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within 24 months (or 27 months, as applicable) from the closing of this offering, we will provide our public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares upon such approval at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our taxes, divided by the number of then outstanding public shares; and

• We will not effectuate our initial business combination with another blank check company or a similar company with nominal operations.

In addition, our amended and restated memorandum and articles of association will provide that under no circumstances will we redeem our public shares in an amount that would cause our net tangible assets to be less than $5,000,001 upon consummation of our initial business combination and after payment of underwriters’ fees and commissions.

The Companies Act permits a company incorporated in the Cayman Islands to amend its memorandum and articles of association with the approval of a special resolution. A company’s articles of association may specify that the approval of a higher majority is required. Accordingly, although we could amend any of the provisions relating to our proposed offering, structure and business plan which are contained in our amended and restated memorandum and articles of association, we view all of these provisions as binding obligations to our shareholders and neither we, nor our officers or directors, will take any action to amend or waive any of these provisions unless we provide dissenting public shareholders with the opportunity to redeem their public shares.

Anti-Money Laundering, Counter Terrorist Financing, Prevention of Proliferation Financing and Financial Sanctions Compliance — Cayman Islands

In order to comply with legislation or regulations aimed at the prevention of money laundering, terrorist financing, proliferation financing and compliance with financial sanctions, we are required to adopt and maintain anti-money laundering procedures, and may require subscribers to provide evidence to verify their identity, the identity of their beneficial owners/controllers and source of funds. Where permitted, and subject to certain conditions, we may also delegate the maintenance of our anti-money laundering, terrorist financing, proliferation financing and compliance with financial sanctions compliance procedures (including the acquisition of due diligence information) to a suitable person.

We reserve the right to request such information as is necessary to verify the identity of a subscriber. In some cases the directors may be satisfied that no further information is required since an exemption applies under the Anti-Money Laundering Regulations (2020 Revision) of the Cayman Islands, as amended and revised from time to time (the “Regulations”). Depending on the circumstances of each application, a detailed verification of identity might not be required where:

(a) the subscriber is a relevant financial business required to comply with the Regulations or is a majority-owned subsidiary of such a business; or

(b) the subscriber is acting in the course of a business in relation to which a regulatory authority exercises regulatory functions and which is in a country assessed by us as having a low degree of risk of money laundering and terrorist financing in accordance with the Regulations (each, a “Low Risk Country”); or

(c) the subscriber is a central or local government organization, statutory body or agency of government in the Cayman Islands or a Low Risk Country; or

(d) the subscriber is a company that is listed on a recognized stock exchange and subject to disclosure requirements which impose requirements to ensure adequate transparency of beneficial ownership, or is a majority-owned subsidiary of such a company; or

(e) the subscriber is a pension fund for a professional association, trade union or is acting on behalf of employees of an entity referred to in sub-paragraphs (a) to (d); or

133

Table of Contents

(f) the application is made through a nominee or introduced by an introducer which falls within one of sub-paragraphs (a) to (e). In this situation the company may rely on a written assurance from the nominee or the introducer (as applicable) which confirms (i) that the requisite identification and verification procedures on the applicant for business and (for introducers only) its beneficial owners have been carried out; (ii) the nature and intended purpose of the business relationship; (iii) that the nominee or the introducer has identified the source of funds of the applicant for business; (iv) (for introducers only) that the introducer is supervised or monitored by an overseas regulatory authority and has measures in place to comply with customer due diligence and record keeping requirements; and (v) that the nominee or the introducer shall make available on request and without delay copies of any identification and verification data or information and relevant documents.

For the purposes of these exceptions, recognition of a financial institution, regulatory authority or jurisdiction will be determined in accordance with the Regulations by reference to the Low Risk Jurisdiction.

In the event of delay or failure on the part of the subscriber in producing any information required for verification purposes, we may refuse to accept the application, in which case any funds received will be returned without interest to the account from which they were originally debited.

We also reserve the right to refuse to make any payment to a shareholder if our directors or officers suspect or are advised that the payment to such shareholder might result in a breach of applicable anti-money laundering, counter-terrorist financing, prevention of proliferation financing and financial sanctions or other laws or regulations by any person in any relevant jurisdiction, or if such refusal is considered necessary or appropriate to ensure our compliance with any such laws or regulations in any applicable jurisdiction.

If any person resident in the Cayman Islands knows or suspects, or has reasonable grounds for knowing or suspecting, that another person is engaged in criminal conduct or is involved with terrorism, terrorist property or proliferation financing or is the target of a financial sanction and the information for that knowledge or suspicion came to their attention in the course of business in the regulated sector or other trade, profession, business or employment, the person will be required to report such knowledge or suspicion to (i) the Financial Reporting Authority of the Cayman Islands, pursuant to the Proceeds of Crime Act (2020 Revision) of the Cayman Islands if the disclosure relates to criminal conduct, money laundering, terrorist financing, proliferation financing or a financial sanctions breach or (ii) a police officer of the rank of constable or higher, or the Financial Reporting Authority, pursuant to the Terrorism Act (2018 Revision) of the Cayman Islands, if the disclosure relates to involvement with terrorism or terrorist financing and property. Such a report will not be treated as a breach of confidence or of any restriction upon the disclosure of information imposed by any enactment or otherwise.

Data Protection — Cayman Islands

We have certain duties under the Data Protection Act, 2017 of the Cayman Islands (the “DPL”) based on internationally accepted principles of data privacy.

In our use of this personal data, we will be characterized as a “data controller” for the purposes of the DPL, while our affiliates and service providers who may receive this personal data from us in the conduct of our activities may either act as our “data processors” for the purposes of the DPL or may process personal information for their own lawful purposes in connection with services provided to us.

We may also obtain personal data from other public sources. Personal data includes, without limitation, the following information relating to a shareholder and/or any individuals connected with a shareholder as an investor: name, residential address, email address, contact details, corporate contact information, signature, nationality, place of birth, date of birth, tax identification, credit history, correspondence records, passport number, bank account details, source of funds details and details relating to the shareholder’s investment activity.

If you are a natural person, this will affect you directly. If you are a corporate investor (including, for these purposes, legal arrangements such as trusts or exempted limited partnerships) that provides us with personal data on individuals connected to you for any reason in relation your investment in the company, this will be relevant for those individuals and you should transmit the content of this Privacy Notice to such individuals or otherwise advise them of its content.

How the Company May Use a Shareholder’s Personal Data

The company, as the data controller, may collect, store and use personal data for lawful purposes, including, in particular:

• where this is necessary for the performance of our rights and obligations under any purchase agreements;

• where this is necessary for compliance with a legal and regulatory obligation to which we are subject (such as compliance with anti-money laundering, counter terrorist financing, prevention of proliferation financing, financial sanctions and FATCA/CRS requirements); and/or

• where this is necessary for the purposes of our legitimate interests and such interests are not overridden by your interests, fundamental rights or freedoms.

Should we wish to use personal data for other specific purposes (including, if applicable, any purpose that requires your consent), we will contact you.

Why We May Transfer Your Personal Data

In certain circumstances we may be legally obliged to share personal data and other information with respect to your shareholding with the relevant regulatory authorities such as the Cayman Islands Monetary Authority or the Tax Information Authority. They, in turn, may exchange this information with foreign authorities, including tax authorities.

Certain Anti-Takeover Provisions of our Amended and Restated Memorandum and Articles of Association

Our amended and restated memorandum and articles of association will provide that our board of directors will be classified into three classes of directors. As a result, in most circumstances, a person can gain control of our board only by successfully engaging in a proxy contest at two or more annual general meetings.

Our authorized but unissued ordinary shares and preference shares are available for future issuances without shareholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved ordinary shares and preference shares could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Extraordinary General Meetings

Our amended and restated memorandum and articles of association will provide that extraordinary general meetings may be called only by a majority vote of our board of directors, by our Chief Executive Officer or by our Chairman.

Advance Notice Requirements for Shareholder Proposals and Director Nominations

Our amended and restated memorandum and articles of association will provide that shareholders seeking to bring business before our annual general meeting, or to nominate candidates for appointment as directors at our annual general meeting must provide timely notice of their intent in writing. To be timely, a shareholder’s notice will need to be received by the company secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the anniversary date of the immediately preceding annual general meeting. Pursuant to Rule 14a-8 under the Exchange Act, proposals seeking inclusion in our annual proxy statement must comply with the notice periods contained therein. Our amended and restated memorandum and articles of association also specify certain requirements as to the form and content of a shareholders’ meeting. These provisions may preclude our shareholders from bringing matters before our annual general meeting or from making nominations for directors at our annual general meeting. Our amended and restated memorandum and articles of association will allow the chairman of the meeting at a meeting of the shareholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These provisions may also defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of us.

136

Table of Contents

Unanimous Written Resolutions

Subsequent to the consummation of the offering, any action required or permitted to be taken by our ordinary shareholders must be effected by a duly called annual general meeting or extraordinary general meeting and may not be effected by unanimous written resolution of the shareholders other than with respect to our Class B ordinary shares.

Classified Board of Directors

Our board of directors will initially be divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. Our amended and restated memorandum and articles of association will provide that the authorized number of directors may be changed only by resolution of the board of directors. Subject to the terms of any preference shares, any or all of the directors may be removed from office at any time, but only for cause and only by the affirmative vote of holders of a majority of the voting power of all then outstanding shares entitled to vote generally in the appointment or removal of directors, voting together as a single class. Any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by a vote of a majority of our directors then in office.

Class B Ordinary Shares Consent Right

For so long as any Class B ordinary shares remain outstanding, we may not, without the prior vote or written consent of the holders of two-thirds of our Class B ordinary shares then outstanding, voting separately as a single class, amend, alter or repeal any provision our amended and restated memorandum and articles of association, including whether by merger, consolidation or otherwise, and whether or not such amendment, alteration or repeal of would alter or change the powers, preferences or relative, participating, optional or other or special rights of the Class B ordinary shares. Any action required or permitted to be taken at any meeting of the holders of Class B ordinary shares may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of the outstanding Class B ordinary shares having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all Class B ordinary shares were present and voted.

Securities Eligible for Future Sale

Immediately after the consummation of this offering, we will have 38,450,000 (or 44,165,000 if the underwriters’ over-allotment option is exercised in full) ordinary shares outstanding. Of these shares, the 30,000,000 shares (or 34,500,000 if the underwriters’ over-allotment option is exercised in full) sold in this offering will be freely tradable without restriction or further registration under the Securities Act, except for any shares purchased by one of our affiliates within the meaning of Rule 144 under the Securities Act. All of the remaining 7,500,000 (or 8,625,000 if the underwriters’ over-allotment option is exercised in full) shares and all 950,000 (or 1,040,000 if the underwriters’ over-allotment option is exercised in full) private placement shares are restricted securities under Rule 144, in that they were issued in private transactions not involving a public offering, and the Class B ordinary shares and private placement shares are subject to transfer restrictions as set forth elsewhere in this prospectus. These restricted securities will be subject to registration rights as more fully described below under “— Registration Rights.”

Rule 144

Pursuant to Rule 144, a person who has beneficially owned restricted ordinary shares for at least six months would be entitled to sell their securities provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale.

137

Table of Contents

Persons who have beneficially owned restricted ordinary shares for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

• 1% of the total number of ordinary shares then outstanding, which will equal 375,000 shares immediately after this offering (or 431,250 if the underwriters exercise their over-allotment option in full); or

• the average weekly reported trading volume of the ordinary shares during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by our affiliates under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

• the issuer of the securities that was formerly a shell company has ceased to be a shell company;

• the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

• the issuer of the securities has filed all Exchange Act reports and materials required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports and materials), other than Current Reports on Form 8-K; and

• at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

As a result, our initial shareholders and Tortoise will be able to sell their founder shares and private placement shares, as applicable, pursuant to Rule 144 without registration one year after we have completed our initial business combination.

Registration Rights

The holders of the founder shares, private placement shares and shares that may be issued upon conversion of working capital loans (and any Class A ordinary shares issuable upon conversion of the founder shares), and any Class A ordinary shares held by our initial shareholders and Tortoise at the completion of this offering or acquired prior to or in connection with our initial business combination, will be entitled to registration rights pursuant to a registration rights agreement to be signed prior to or on the effective date of the registration statement of which this prospectus forms a part, requiring us to register such securities for resale (in the case of the founder shares, only after conversion to our Class A ordinary shares). The holders of these securities, having a value of at least $25 million in the aggregate, are entitled to make up to three demands that we offer such securities in an underwritten offering. These holders also have certain “piggy-back” registration rights with respect to certain underwritten offerings we may conduct. We will bear the expenses incurred in connection with registering these securities.

Listing of Securities

We intend to apply to list our Class A ordinary shares on the NYSE under the symbol “TRTL.” We expect that our Class A ordinary shares will be listed on the NYSE on or promptly after the effective date of the registration statement. We cannot guarantee that our Class A ordinary shares will be approved for listing on the NYSE.

CERTAIN Income Tax Considerations

The following is a discussion of the material Cayman Islands and U.S. federal income tax considerations with respect to an investment in our Class A ordinary shares. This discussion is based upon laws and relevant interpretations thereof in effect as of the date of this prospectus, all of which are subject to change. This discussion does not address all possible tax considerations with respect to an investment in our Class A ordinary shares, such as the tax considerations under state, local and other tax laws.

Prospective investors should consult with and rely solely upon their own tax advisors regarding the possible tax consequences of investing in our Class A ordinary shares under the laws of their country of citizenship, residence or domicile.

Cayman Islands Taxation

The following is a discussion on certain Cayman Islands income tax consequences of an investment in our Class A ordinary shares. The discussion is a general summary of present law, which is subject to prospective and retroactive change. It is not intended as tax advice, does not consider any investor’s particular circumstances, and does not consider tax consequences other than those arising under Cayman Islands law.

Under Existing Cayman Islands Laws

Payments of dividends and capital in respect of our Class A ordinary shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of the Class A ordinary shares nor will gains derived from the disposal of the Class A ordinary shares be subject to Cayman Islands income or corporate tax. The Cayman Islands currently has no income, corporation or capital gains tax and no estate duty, inheritance tax or gift tax.

No stamp duty is payable in respect of the issue of the Class A ordinary shares. An instrument of transfer in respect of a Class A ordinary share is stampable if executed in or brought into the Cayman Islands.

The company has been incorporated under the laws of the Cayman Islands as an exempted company with limited liability and, as such, has applied for and received an undertaking from the Financial Secretary of the Cayman Islands in a form substantially similar to the following:

“The Tax Concessions Act
Undertaking as to Tax Concessions

In accordance with The Tax Concessions Act, the following undertaking hereby given to TortoiseEcofin Acquisition Corp. III (“the Company”):

1. That no law which is hereafter enacted in the Islands imposing any tax to be levied on profits, income, gains or appreciations shall apply to the Company or its operations; and

2. In addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable:

2.1 on or in respect of the shares, debentures or other obligations of the Company; or

2.2 by way of the withholding in whole or part of any relevant payment as defined in the Tax Concessions Act.

These concessions shall be for a period of THIRTY years from the date hereof.”

U.S. Federal Income Tax Considerations

General

The following is a discussion of the material U.S. federal income tax considerations related to the acquisition, ownership and disposition by U.S. Holders (as defined below) and Non-U.S. Holders (as defined below) of our Class A ordinary shares. This discussion applies only to our Class A ordinary shares that are held as a capital asset

139

Table of Contents

for U.S. federal income tax purposes (generally property held for investment) and is applicable only to holders who purchased Class A ordinary shares in this offering. Further, this discussion assumes any distributions on Class A ordinary shares will be paid in U.S. dollars.

This discussion is based on the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations, administrative rulings and judicial decisions, all as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect. We cannot assure you that a change in law will not significantly alter the tax considerations that we describe in this summary. We have not sought any ruling from the IRS or formal written opinion from our tax advisors with respect to the statements made and the positions or conclusions described in the following summary. Such statements, positions and conclusions are not free from doubt, and there can be no assurance that your tax advisor, the IRS or a court will agree with such statements and conclusions.

This summary does not address the Medicare tax on certain investment income, U.S. federal estate or gift tax laws, any state, local or non-U.S. tax laws, any tax treaties or any other tax law. Furthermore, this discussion does not address all U.S. federal income tax considerations that may be relevant to a particular holder in light of the holder’s circumstances or that may be relevant to certain categories of investors that may be subject to special rules, such as (but not limited to):

• our founders, sponsor, officers or directors or other holders of our Class B ordinary shares or private placement shares;

• banks, insurance companies or other financial institutions;

• tax-exempt or governmental organizations;

• “qualified foreign pension funds” as defined in Section 897(l)(2) of the Code (or any entities all of the interests of which are held by a qualified foreign pension fund);

• dealers in securities or foreign currencies;

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

• traders in securities that use the mark-to-market method of accounting for U.S. federal income tax purposes;

• entities or arrangements treated as partnerships or pass-through entities for U.S. federal income tax purposes or holders of interests therein;

• persons deemed to sell our Class A ordinary shares under the constructive sale provisions of the Code;

• persons that acquired our Class A ordinary shares through the exercise of employee share options or otherwise as compensation or through a tax-qualified retirement plan;

• U.S. Holders (as defined below) whose functional currency is not the U.S. dollar;

• persons that actually or constructively own five percent or more of any class of our shares;

• certain former citizens or long-term residents of the United States; and

• persons that hold our Class A ordinary shares as part of a straddle, appreciated financial position, synthetic security, hedge, conversion transaction or other integrated investment or risk reduction transaction.

PROSPECTIVE INVESTORS ARE ENCOURAGED TO CONSULT WITH AND RELY SOLELY UPON THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS (INCLUDING ANY POTENTIAL FUTURE CHANGES THERETO) TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR CLASS A ORDINARY SHARES ARISING UNDER ANY OTHER TAX LAWS, INCLUDING BUT NOT LIMITED TO, THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Table of Contents

U.S. Holder and Non-U.S. Holder Defined

A “U.S. Holder” is a beneficial owner of our Class A ordinary shares that, for U.S. federal income tax purposes, is:

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

• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or 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 (A) the administration of which is subject to the primary supervision of a U.S. court and which has one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) who have the authority to control all substantial decisions of the trust or (B) that has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

A “Non-U.S. Holder” is a beneficial owner of our Class A ordinary shares that is, for U.S. federal income tax purposes, an individual, corporation, estate or trust, in each case that is not a U.S. Holder.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our Class A ordinary shares, the tax treatment of a partner in such partnership might depend upon the status of the partner or the partnership, upon the activities of the partnership and upon certain determinations made at the partnership or partner level. Accordingly, we urge partners in partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) considering the purchase of our Class A ordinary shares to consult with and rely solely upon their tax advisors regarding the U.S. federal income and other tax considerations of the purchase, ownership and disposition of our Class A ordinary shares by such partnership.

Considerations for U.S. Holders

This section applies to you if you are a U.S. Holder.

Tax Characterization of Distributions with Respect to Class A Ordinary Shares

If we pay distributions of cash or other property to U.S. Holders of our Class A ordinary shares, such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our current and accumulated earnings and profits will constitute a return of capital to the extent of the U.S. Holder’s adjusted tax basis in our Class A ordinary shares, that will be applied against and reduce (but not below zero) the U.S. Holder’s adjusted tax basis in our Class A ordinary shares. Any remaining portion of the distribution will be treated as gain recognized on the sale or exchange of our Class A ordinary shares and will be treated as described under “— Considerations for U.S. Holders — Gain or Loss on Sale or Other Taxable Exchange or Disposition of Class A Ordinary Shares” below.

Distributions Treated as Dividends

Dividends paid by us will be taxable to a corporate U.S. Holder at regular rates and will not be eligible for the dividends-received deduction generally allowed to domestic corporations in respect of dividends received from other domestic corporations. Dividends we pay to a non-corporate U.S. Holder generally will constitute a “qualified dividend” that will be subject to U.S. federal income tax at the lower applicable long-term capital gains rate only if our Class A ordinary shares are readily tradable on an established securities market in the United States and certain holding period and other requirements are met, including that we are not classified as a PFIC during the taxable year in which the dividend is paid or a preceding taxable year. It is unclear whether the redemption rights with respect to the Class A ordinary shares described in this prospectus may be deemed a limitation of a shareholder’s risk of loss and prevent a U.S. Holder from satisfying the applicable holding period requirements. If the applicable holding period requirements are not satisfied, a non-corporate U.S. Holder may be subject to tax on the dividend at regular ordinary income tax rates instead of the preferential income tax rate that applies to qualified dividend income. U.S. Holders should consult with and rely solely upon their tax advisors regarding the availability of the lower preferential income tax rate for qualified dividend income for any dividends paid with respect to our Class A ordinary shares.

Gain or Loss on Sale or Other Taxable Exchange or Disposition of Class A Ordinary Shares

Subject to the PFIC rules discussed below, upon a sale or other taxable disposition of our Class A ordinary shares (which in general would include a redemption of our Class A ordinary shares that is treated as a sale of such Class A ordinary shares as described below, including as a result of a dissolution and liquidation in the event we do not consummate an initial business combination within the required time period), a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis with respect to its Class A ordinary shares. Generally, the amount of gain or loss recognized by a U.S. Holder will be an amount equal to the difference between (i) the sum of the amount of cash and the fair market value of any property received in such disposition and (ii) the U.S. Holder’s adjusted tax basis in the relevant Class A ordinary shares. A U.S. Holder’s adjusted tax basis in its Class A ordinary shares generally will equal the U.S. Holder’s acquisition cost less any prior distributions treated as a return of capital, as discussed above.

Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for the Class A ordinary shares so disposed of exceeds one year. Long-term capital gains recognized by non-corporate U.S. Holders may be eligible to be taxed at reduced rates, whereas short-term capital gains would be taxed at regular ordinary income tax rates. It is unclear, however, whether the redemption rights with respect to the Class A ordinary shares described in this prospectus may be deemed to be a limitation of a shareholder’s risk of loss and suspend the running of the applicable holding period for this purpose. If the running of the holding period for the Class A ordinary shares is suspended, U.S. Holders may not be able to satisfy the one-year holding period requirement for long-term capital gain treatment. If the one-year holding period is not satisfied, any gain on a sale or other taxable disposition of the Class A ordinary shares would be subject to short-term capital gain treatment and, in the case of non-corporate U.S. Holders, would be taxed at regular ordinary income tax rates. In addition, the deductibility of capital losses is subject to limitations.

Redemption or Repurchase of Class A Ordinary Shares for Cash

Subject to the PFIC rules discussed below, in the event that a U.S. Holder’s Class A ordinary shares are redeemed pursuant to the redemption provisions described in this prospectus under the section entitled “Description of Securities — Ordinary Shares” or if we repurchase a U.S. Holder’s Class A ordinary shares in an open market transaction (generally referred to herein as a “redemption”), the treatment of the redemption for U.S. federal income tax purposes will depend on whether it qualifies as a sale of the Class A ordinary shares under Section 302 of the Code. If the redemption qualifies as a sale of Class A ordinary shares, the U.S. Holder will be treated as described under “— Considerations for U.S. Holders — Gain or Loss on Sale or Other Taxable Exchange or Disposition of Class A Ordinary Shares” above. If the redemption does not qualify as a sale of Class A ordinary shares, the U.S. Holder will be treated as receiving a distribution from us with the tax consequences described above under “— Considerations for U.S. Holders — Tax Characterization of Distributions with Respect to Class A Ordinary Shares.”

Whether a redemption qualifies for sale treatment will depend largely on the total number of our ordinary shares treated as held by the U.S. Holder (including any shares constructively owned by the U.S. Holder) relative to all of our shares outstanding both before and after the redemption. The redemption of our Class A ordinary shares generally will be treated as a sale of Class A ordinary shares (rather than as a distribution from us) if the redemption satisfies one of the following tests (which we refer to as the “redemption sale tests”): (i) it is “substantially disproportionate” with respect to the U.S. Holder, (ii) it results in a “complete termination” of the U.S. Holder’s interest in us, or (iii) it is “not essentially equivalent to a dividend” with respect to the U.S. Holder. In determining whether any of the redemption sale tests is satisfied, a U.S. Holder takes into account not only shares actually owned by the U.S. Holder, but also our ordinary shares that are “constructively” owned by it. In addition to shares owned directly, a U.S. Holder may constructively own (i) shares owned by certain related individuals or entities in which the U.S. Holder has an interest or that have an interest in such U.S. Holder and (ii) any shares the U.S. Holder has a right to acquire by exercise of an option.

In order to meet the “substantially disproportionate” test, the percentage of our outstanding voting shares actually and constructively owned by the U.S. Holder immediately following the redemption of our Class A ordinary shares must, among other requirements, be less than 80% of the percentage of our outstanding voting shares actually and constructively owned by the U.S. Holder immediately before the redemption. Prior to our initial business combination, the Class A ordinary shares may not be treated as voting shares for this purpose and, consequently,

142

Table of Contents

this substantially disproportionate test may not be applicable. There will be a “complete termination” of a U.S. Holder’s interest if either (i) all of the ordinary shares both actually and constructively owned by the U.S. Holder are redeemed or (ii) all of the ordinary shares actually owned by the U.S. Holder are redeemed, the U.S. Holder is eligible to waive and effectively waives in accordance with specific rules the constructive attribution of shares owned by certain family members, and the U.S. Holder does not constructively own any other ordinary shares. The redemption of our Class A ordinary shares will not be “essentially equivalent to a dividend” if a U.S. Holder’s redemption results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in us. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in us will depend on the particular facts and circumstances, but the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.”

If none of the redemption sale tests is satisfied, the redemption will be treated as a distribution from us and the tax considerations will be as described under “— Considerations for U.S. Holders — Tax Characterization of Distributions with Respect to Class A Ordinary Shares,” above. After the application of those rules, any remaining tax basis of the U.S. Holder in the redeemed Class A ordinary shares will be added to the U.S. Holder’s adjusted tax basis in its remaining shares, or, if it has none, possibly to the U.S. holder’s adjusted tax basis in other ordinary shares owned by it.

U.S. Holders who actually or constructively own five percent (or if our Class A ordinary shares are not then publicly traded, one percent) or more of our shares (by vote or value) may be subject to special reporting requirements with respect to a redemption of our Class A ordinary shares. A U.S. Holder should consult with and rely solely upon its own tax advisors as to the tax consequences of a redemption.

Passive Foreign Investment Company Rules

Adverse U.S. federal income tax rules apply to U.S. Holders that hold shares in a foreign (i.e., non-U.S.) corporation classified as a PFIC for U.S. federal income tax purposes. In general, we will be treated as a PFIC with respect to a U.S. Holder in any taxable year in which, after applying certain look-through rules, either:

(i) at least 75% of our gross income for such taxable year, including our pro rata share of the gross income of any corporation in which we are considered to own at least 25% of the shares by value, consists of passive income (which generally includes dividends, interest, rents and royalties (other than rents or royalties derived from the active conduct of a trade or business) and gains from the disposition of passive assets); or

(ii) at least 50% of our assets in a taxable year (ordinarily determined based on fair market value and averaged quarterly over the year), including our pro rata share of the assets of any corporation in which we are considered to own at least 25% of the shares by value, produce or are held for the production of passive income.

Because we are a blank check company with no current active business, we believe that it is likely that we will meet one or both of the PFIC tests during the taxable years prior to our acquisition of a company or assets in a business combination (including any short taxable year that might result from a business combination), which would generally result in us being treated as a PFIC in those taxable years. However, pursuant to a “start-up exception,” a corporation will not be a PFIC for the first taxable year the corporation has gross income (the “start-up year”), if (1) no predecessor of the corporation was a PFIC, (2) the corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the start-up year, and (3) the corporation is not in fact a PFIC for either of those years. If the start-up exception were to apply to us, we would not be a PFIC during our start-up year. The applicability of the start-up exception to us is uncertain, however, and will not be known until, at the earliest, after the close of our current taxable year (and might not be known until after the close of the second taxable year following our start-up year). Therefore, we cannot assure you that we will qualify for the start-up exception. Furthermore, we could meet one or both of the PFIC tests following our start-up year, and whether we do so may depend on, among other things, the timing of our business combination, the amount of our passive income and assets in the year of the business combination, whether we combine with a U.S. or non-U.S. target company, and the amount of passive income and assets of the acquired business. In such case, we would likely be treated as a PFIC in

143

Table of Contents

those taxable years (and likely would not qualify for the start-up exception). Our actual PFIC status for our current taxable year or any subsequent taxable year will not be determinable until after the end of such taxable year. We cannot assure you that we will not be a PFIC in our current taxable year or in any future taxable year.

Although our PFIC status is determined each taxable year, an initial determination that we are a PFIC will generally apply for subsequent years to a U.S. Holder who held (or is deemed to have held) Class A ordinary shares while we were a PFIC, whether or not we are treated as a PFIC in those subsequent years. If we are treated as a PFIC for any taxable year in which a U.S. Holder holds our Class A ordinary shares (regardless of whether we remain a PFIC for subsequent taxable years) and the U.S. Holder did not make either a timely qualified electing fund (“QEF”) election or a mark-to-market election (in either case, as described below), such U.S. Holder generally will be subject to special rules with respect to (i) any gain realized on the sale or other disposition of its Class A ordinary shares and (ii) any “excess distribution” (generally, the portion of any distributions received by such U.S. Holder during a taxable year in excess of 125% of the average annual distributions received by such U.S. Holder during the three preceding taxable years or, if shorter, such U.S. Holder’s holding period for the Class A ordinary shares). Under these rules:

• the U.S. Holder’s gain or excess distribution will be allocated ratably over the U.S. Holder’s holding period for the Class A ordinary shares;

• the amount allocated to the U.S. Holder’s taxable year in which the U.S. Holder realized the gain or received the excess distribution, or to the portion of the U.S. Holder’s holding period prior to the first day of our first taxable year in which we are a PFIC, will be taxed as ordinary income; and

• the amount allocated to each of the other taxable years (or portions thereof) of the U.S. Holder will be subject to tax at the highest tax rate in effect for the U.S. Holder in that year, and an interest charge for the deemed deferral benefit will be imposed with respect to the resulting tax attributable to each such other taxable year (or portion thereof).

In general, if we are treated as a PFIC, a U.S. Holder may be able to avoid the PFIC tax consequences described above in respect of our Class A ordinary shares by making a timely and valid QEF election (if eligible to do so) in the first taxable year in which the U.S. Holder held (or was deemed to hold) Class A ordinary shares in which we are classified as a PFIC. If a U.S. Holder makes a timely QEF election with respect to our Class A ordinary shares, each year such U.S. Holder will be required to include in its income its pro rata share of our net capital gains (as long-term capital gain) and our ordinary earnings (as ordinary income), if any, for our taxable year that ends with or within the taxable year of the U.S. Holder, regardless of whether or not we make distributions to such U.S. Holder (although a U.S. Holder generally may make a separate election to defer the payment of taxes on undistributed income inclusions under the QEF rules, but if deferred, any such taxes will be subject to an interest charge). Such U.S. Holder’s adjusted tax basis in our Class A ordinary shares will be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that had been previously taxed will result in a corresponding reduction in the adjusted tax basis in the Class A ordinary shares and will not be taxed again once distributed. A U.S. Holder that has made a timely QEF election with respect to our Class A ordinary shares will generally recognize capital gain or loss on the sale or other disposition of our Class A ordinary shares, and no additional tax or interest charge will be imposed under the PFIC rules.

The QEF election is made on a shareholder-by-shareholder basis and, once made, will apply to all subsequent taxable years of the U.S. Holder during which it holds Class A ordinary shares, unless we cease to be a PFIC or unless revoked by the U.S. Holder with the consent of the IRS. A U.S. Holder generally makes a QEF election by attaching a completed IRS Form 8621, including the information provided in a PFIC annual information statement (discussed below), to a timely filed U.S. federal income tax return for the tax year to which the election relates. Retroactive QEF elections generally may be made only by filing a protective statement with such return and if certain other conditions are met or with the consent of the IRS. U.S. Holders should consult with and rely solely upon their tax advisors regarding the availability and tax consequences of a retroactive QEF election in their particular circumstances.

In order to comply with the requirements of a QEF election, a U.S. Holder must receive a PFIC annual information statement from us. If we determine we are a PFIC for any taxable year, upon written request by a U.S. Holder, we will endeavor to provide to such U.S. Holder such information as the IRS may require, including a PFIC

144

Table of Contents

annual information statement, in order to enable such U.S. Holder to make and maintain a QEF election, but there is no assurance that we will timely provide such required information. There is also no assurance that we will have timely knowledge of our status as a PFIC in the future or of the required information to be provided.

A U.S. Holder that does not make a timely QEF election in the first taxable year (or portion thereof) in which we are a PFIC that is included in the holding period of such U.S. Holder may be able to mitigate the adverse PFIC tax consequences by making a QEF election in a subsequent taxable year and simultaneously making a purging election under the PFIC rules. Under one type of purging election, the U.S. Holder will be deemed to have sold its Class A ordinary shares at their fair market value, and any gain recognized on such deemed sale will be treated as an excess distribution, as described above. As a result of this purging election, the U.S. Holder will have additional basis (to the extent of any gain recognized on the deemed sale) and, solely for purposes of the PFIC rules, a new holding period in such holder’s Class A ordinary shares. U.S. Holders are strongly urged to consult with and rely solely upon their tax advisors regarding the application of the rules governing purging elections to their particular circumstances (including the availability of a separate “deemed dividend” purging election that may be available if we are a controlled foreign corporation).

Alternatively, if we are treated as a PFIC and our Class A ordinary shares are treated as “marketable stock,” a U.S. Holder that holds our Class A ordinary shares at the close of a taxable year may make a mark-to-market election with respect to such Class A ordinary shares, provided the U.S. Holder completes and files IRS Form 8621 in accordance with the relevant instructions and related U.S. Treasury regulations. The mark-to-market election is available only for “marketable stock,” which generally includes stock that is regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, including the NYSE (on which we intend to list the Class A ordinary shares), or on a foreign exchange or market that the IRS determines has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. If made, a mark-to-market election would be effective for the taxable year for which the election was made and for all subsequent taxable years unless the Class A ordinary shares ceased to qualify as “marketable stock” for purposes of the PFIC rules or the IRS consented to the revocation of the election. U.S. Holders should consult with and rely solely upon their own tax advisors regarding the availability and tax consequences of a mark-to-market election in respect of our Class A ordinary shares in their particular circumstances.

If the U.S. Holder makes a valid mark-to-market election for the first taxable year of the U.S. Holder in which the U.S. Holder holds (or is deemed to hold) our Class A ordinary shares and in which we are treated as a PFIC, such U.S. Holder generally will not be subject to the PFIC rules described above in respect of Class A ordinary shares. Instead, in general, such U.S. Holder will include as ordinary income in each taxable year the excess, if any, of the fair market value of its Class A ordinary shares at the end of the taxable year over its adjusted basis in its Class A ordinary shares. These amounts of ordinary income would not be eligible for the favorable tax rates applicable to qualified dividend income or long-term capital gains. Such U.S. Holder also will be permitted an ordinary loss in respect of the excess, if any, of its adjusted basis of its Class A ordinary shares over the fair market value of its Class A ordinary shares at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. Such U.S. Holder’s basis in its Class A ordinary shares will be adjusted to reflect any such income or loss amounts. Any gain recognized by such U.S. Holder on a sale or other disposition of its Class A ordinary shares will be treated as ordinary income, and any loss recognized on the sale or other disposition of its Class A ordinary shares will be treated as ordinary loss to the extent that such loss does not exceed the net mark-to-market gains previously included by the U.S. Holder.

If we are a PFIC and, at any time, have a direct or indirect interest in another entity that is treated as a PFIC (a “subsidiary PFIC”), each U.S. Holder generally would be treated as owning its pro rata share by value of the stock of such subsidiary PFIC, and generally could incur liability for the deferred tax and interest charge described in the general PFIC rules above if we receive a distribution from, or dispose of all or part of our interest in, the subsidiary PFIC or the U.S. Holder is otherwise deemed to have disposed of an interest in the subsidiary PFIC. Upon written request by a U.S. Holder, we will endeavor to cause any subsidiary PFIC to provide to such U.S. Holder the information that may be required to make or maintain a QEF election with respect to the subsidiary PFIC. There can be no assurance that we will have timely knowledge of the status of any such subsidiary PFIC. In addition, we may not hold a controlling interest in any such subsidiary PFIC and thus there can be no assurance we will be able to cause the subsidiary PFIC to provide such required information. A mark-to-market election generally would not be available with respect to a subsidiary PFIC. U.S. Holders are urged to consult with and rely solely upon their tax advisors regarding the tax issues raised by subsidiary PFICs.

145

Table of Contents

A U.S. Holder that owns (or is deemed to own) shares in a PFIC during any taxable year of the U.S. Holder may have to file an IRS Form 8621 (whether or not a QEF or mark-to-market election is made) and such other information as may be required by the United States Department of the Treasury. Failure to do so, if required, may subject such U.S. Holder to substantial penalties and will extend the statute of limitations on the assessment and collection of all U.S. federal income taxes of such person for the related tax year until such required information is furnished to the IRS.

The rules dealing with PFICs and with the QEF election and the mark-to-market election are very complex and are affected by various factors in addition to those described above. Accordingly, U.S. Holders of our Class A ordinary shares are strongly urged to consult with and rely solely upon their own tax advisors regarding the application of the PFIC rules to them in their particular circumstances.

Information Reporting and Backup Withholding

Information reporting requirements generally will apply to dividends paid to a U.S. Holder and to the proceeds of the sale or other disposition of our Class A ordinary shares unless the U.S. Holder is an exempt recipient and certifies to such exempt status. Backup withholding may apply to such payments if the U.S. Holder fails to provide a taxpayer identification number or a certification of exempt status or has been notified by the IRS that it is subject to backup withholding (and such notification has not been withdrawn). Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is timely furnished to the IRS.

Certain U.S. Holders may be required to file an IRS Form 926 (Return by a U.S. Transferor of Property to a Foreign Corporation) to report a transfer of property (including cash) to us. Substantial penalties may be imposed on a U.S. Holder that fails to comply with this reporting requirement and the period of limitations on assessment and collection of U.S. federal income taxes will be extended in the event of a failure to comply. Furthermore, certain U.S. Holders who are individuals and certain entities will be required to report information with respect to such U.S. Holder’s investment in “specified foreign financial assets” on IRS Form 8938 (Statement of Specified Foreign Financial Assets), subject to certain exceptions. An interest in us constitutes a specified foreign financial asset for these purposes. Persons who are required to report specified foreign financial assets and fail to do so may be subject to substantial penalties and the period of limitations on assessment and collection of U.S. federal income taxes will be extended in the event of a failure to comply. Potential investors are urged to consult with and rely solely upon their tax advisors regarding the foreign financial asset and other reporting obligations and their application to an investment in our Class A ordinary shares.

Considerations for Non-U.S. Holders

This section applies to you if you are a Non-U.S. Holder.

Tax Characterization of Distributions with Respect to Class A Ordinary Shares

The determination of the extent to which a distribution will constitute a dividend, return of capital or gain from the sale of shares is generally the same for Non-U.S. Holders as that described in “— Considerations for U.S. Holders — Tax Characterization of Distributions with Respect to Class A Ordinary Shares.” To the extent a distribution constitutes gain from the sale of our Class A Ordinary Shares, see “— Considerations for Non-U.S. Holders — Gain or Loss on Sale or Other Taxable Exchange or Disposition of Class A Ordinary Shares” below, and to the extent such distribution constitutes a dividend, see “— Considerations for Non-U.S. Holders — Distributions Treated as Dividends.”

Distributions Treated as Dividends

Dividends paid to a Non-U.S. Holder generally will not be subject to U.S. federal income tax, unless the dividends are effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (and, if required by an applicable income tax treaty, that are treated as attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States). Any such effectively connected dividends generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons. If the

146

Table of Contents

Non-U.S. Holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected dividends.

Gain or Loss on Sale or Other Taxable Exchange or Disposition of Class A Ordinary Shares

Subject to the discussion below under “— Considerations for Non-U.S. Holders — Information Reporting and Backup Withholding,” a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on any gain realized upon the sale or other disposition of our Class A ordinary shares (including a redemption of our Class A ordinary shares as a result of a dissolution and liquidation in the event we do not consummate an initial business combination within the required time period), unless such gain is effectively connected with a trade or business conducted by the Non-U.S. Holder in the United States (and if required by an applicable income tax treaty, is treated as attributable to a permanent establishment maintained by the Non-U.S. Holder in the United States). Any such effectively connected gain generally will be taxed on a net income basis at the rates and in the manner generally applicable to United States persons. If the Non-U.S. Holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax (at a 30% rate or such lower rate as specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected gain.

Redemption or Repurchase of Class A Ordinary Shares for Cash

The characterization for U.S. federal income tax purposes of the redemption of a Non-U.S. Holder’s Class A ordinary shares pursuant to the redemption provisions described in the section of this prospectus entitled “Description of Securities — Ordinary Shares” or our repurchase of a Non-U.S. Holder’s Class A ordinary shares in an open market transaction generally will correspond to the U.S. federal income tax characterization of such a redemption or repurchase of a U.S. Holder’s Class A Ordinary Shares, as described under “— Considerations for U.S. Holders — Redemption or Repurchase of Class A Ordinary Shares for Cash” above, and the consequences of the redemption or repurchase to the Non-U.S. Holder will correspond to that described above in “— Considerations for Non-U.S. Holders — Distributions Treated as Dividends” and “— Considerations for Non-U.S. Holders — Gain on Sale or Other Taxable Exchange or Disposition of Class A Ordinary Shares” accordingly.

Information Reporting and Backup Withholding

Information reporting requirements and possible United States backup withholding may apply to dividends paid to a Non-U.S. Holder and to the proceeds of the sale or other disposition of our Class A ordinary shares unless the Non-U.S. Holder is an exempt recipient and certifies to such exempt status. A Non-U.S. Holder generally will eliminate the requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8BEN, IRS Form W-8BEN-E (or other applicable or successor form). Backup withholding is not an additional tax. Rather, the U.S. federal income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund generally may be obtained, provided that the required information is timely furnished to the IRS.

INVESTORS CONSIDERING THE PURCHASE OF OUR CLASS A ORDINARY SHARES ARE URGED TO CONSULT WITH AND RELY SOLELY UPON THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE APPLICABILITY AND EFFECT OF ANY OTHER TAX LAWS, INCLUDING BUT NOT LIMITED TO, U.S. FEDERAL ESTATE AND GIFT TAX LAWS AND ANY STATE, LOCAL OR NON-U.S. TAX LAWS AND TAX TREATIES.

If all the Class A ordinary shares are not sold at the initial offering price following the initial offering, the representatives may change the offering price and other selling terms. The offering of the Class A ordinary shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The expenses of the offering that are payable by us are estimated to be approximately $2,500,000 (excluding underwriting discounts and commissions). We have agreed to pay for the FINRA-related fees and expenses of the underwriters’ legal counsel, not to exceed $25,000.

Option to Purchase Additional Class A Ordinary Shares

If the underwriters sell more Class A ordinary shares than the total number set forth in the table above, we have granted the underwriters an option exercisable for 45 days after the date of this prospectus to purchase, from time to time, in whole or in part, up to an aggregate of 4,500,000 Class A ordinary shares from us at the public offering price less underwriting discounts and commissions. The underwriters may exercise this option solely for the purpose of covering over-allotments, if any, in connection with this offering. To the extent that this option is exercised, each underwriter will be obligated, subject to certain conditions, to purchase its pro rata portion of these additional Class A ordinary shares based on the underwriters’ percentage underwriting commitment in the offering as indicated in the table at the beginning of this Underwriting section.

Directed Shares Program

At our request, the underwriters have agreed to reserve up to 100,000 of the Class A ordinary shares offered by this prospectus for sale to certain members of Tortoise, at the initial public offering price. Sales in the Directed Shares Program will be made at our direction by Goldman Sachs & Co. LLC. The underwriters will receive the same underwriting discount on any shares purchased pursuant to this program as they will on any other shares sold to the public in this offering. We do not know if individual investors will choose to purchase all or any portion of these reserved Class A ordinary shares, but any purchases they do make will reduce the number of Class A ordinary shares available in the overall offering. Any reserved Class A ordinary shares not purchased in the Directed Shares Program will be offered by the underwriters to the general public on the same terms as the other Class A ordinary shares.

Letter Agreements

We, Tortoise, our sponsor and our officers and directors have agreed that, for a period of 185 days from the date of this prospectus, we and they will not, without the prior written consent of Barclays Capital Inc. and Goldman Sachs & Co. LLC, offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any ordinary shares or any other securities convertible into, or exercisable, or exchangeable for, ordinary shares, subject to certain exceptions. Barclays Capital Inc. and Goldman Sachs & Co. LLC in their sole discretion may release any of the securities subject to these lock-up agreements at any time without notice, other than in the case of the officers and directors, which shall be with notice. Tortoise and our sponsor, officers and directors are also subject to separate transfer restrictions on their founder shares and private placement shares pursuant to the letter agreement described herein.

149

Table of Contents

Our initial shareholders have agreed not to transfer, assign or sell any founder shares held by them until one year after the date of the consummation of our initial business combination or earlier if, subsequent to our business combination, (i) the last sale price of our ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations and recapitalizations) for any 20 trading days within any 30-trading day period commencing at least 150 days after our initial business combination or (ii) we consummate a subsequent liquidation, merger, share exchange or other similar transaction that results in all of our shareholders having the right to exchange their ordinary shares for cash, securities or other property (except with respect to permitted transferees as described herein under the section of this prospectus entitled “Principal Shareholders — Transfers of Founder Shares and Private Placement Shares”). The private placement shares will not be transferable, assignable or salable until 30 days after the completion of our initial business combination (except with respect to permitted transferees as described herein under the section of this prospectus entitled “Principal Shareholders — Transfers of Founder Shares and Private Placement Shares”).

Offering Price Determination

Prior to this offering, there has been no public market for our securities. Consequently, the initial public offering price for the Class A ordinary shares was determined by negotiations between us and the representatives. Among the factors considered in determining initial public offering price were the history and prospects of companies whose principal business is the acquisition of other companies, prior offerings of those companies, our management, our capital structure and currently prevailing general conditions in equity securities markets, including current market valuations of publicly traded companies considered comparable to our company. We cannot assure you, however, that the price at which the Class A ordinary shares will sell in the public market after this offering will not be lower than the initial public offering price or that an active trading market in our Class A ordinary shares will develop and continue after this offering.

Indemnification

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make for these liabilities.

Stabilization, Short Positions and Penalty Bids

The representatives may engage in stabilizing transactions, short sales and purchases to cover positions created by short sales, and penalty bids or purchases for the purpose of pegging, fixing or maintaining the price of the Class A ordinary shares, in accordance with Regulation M under the Exchange Act:

• Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

• A short position involves a sale by the underwriters of Class A ordinary shares in excess of the number of Class A ordinary shares the underwriters are obligated to purchase in the offering, which creates the syndicate short position. This short position may be either a covered short position or a naked short position. In a covered short position, the number of Class A ordinary shares involved in the sales made by the underwriters in excess of the number of Class A ordinary shares they are obligated to purchase is not greater than the number of Class A ordinary shares that they may purchase by exercising their option to purchase additional Class A ordinary shares. In a naked short position, the number of Class A ordinary shares involved is greater than the number of Class A ordinary shares in their option to purchase additional Class A ordinary shares. The underwriters may close out any short position by either exercising their option to purchase additional Class A ordinary shares and/or purchasing Class A ordinary shares in the open market. In determining the source of Class A ordinary shares to close out the short position, the underwriters will consider, among other things, the price of Class A ordinary shares available for purchase in the open market as compared to the price at which they may purchase Class A ordinary shares through their option to purchase additional Class A ordinary shares. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the Class A ordinary shares in the open market after pricing that could adversely affect investors who purchase in the offering.

150

Table of Contents

• Syndicate covering transactions involve purchases of the Class A ordinary shares in the open market after the distribution has been completed in order to cover syndicate short positions.

• Penalty bids permit the representatives to reclaim a selling concession from a syndicate member when the Class A ordinary shares originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our Class A ordinary shares or preventing or retarding a decline in the market price of the Class A ordinary shares. As a result, the price of the Class A ordinary shares may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the NYSE or otherwise and, if commenced, may be discontinued at any time.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Class A ordinary shares. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these stabilizing transactions or that any transaction, once commenced, will not be discontinued without notice.

Electronic Distribution

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by one or more of the underwriters and/or selling group members participating in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the particular underwriter or selling group member, prospective investors may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of Class A ordinary shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the representatives on the same basis as other allocations.

Other than the prospectus in electronic format, the information on any underwriter’s or selling group member’s website and any information contained in any other website maintained by an underwriter or selling group member is not part of the prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or any underwriter or selling group member in its capacity as underwriter or selling group member and should not be relied upon by investors.

Discretionary Sales

The underwriters have informed us that they do not intend to make sales to discretionary accounts.

Other Relationships

We are not under any contractual obligation to engage any of the underwriters to provide any services for us after this offering, and have no present intent to do so. However, any of the underwriters may introduce us to potential target businesses or assist us in raising additional capital in the future. If any of the underwriters provide services to us after this offering, we may pay such underwriter fair and reasonable fees that would be determined at that time in an arm’s length negotiation; provided that no agreement will be entered into with any of the underwriters and no fees for such services will be paid to any of the underwriters prior to the date that is 60 days from the date of this prospectus, unless such payment would not be deemed underwriters’ compensation in connection with this offering and we may pay the underwriters of this offering or any entity with which they are affiliated a finder’s fee or other compensation for services rendered to us in connection with the completion of a business combination.

III (the “Company”) as of February 9, 2021, the related statements of operations, changes in shareholder’s equity and cash flows for the period from February 3, 2021 (inception) through February 9, 2021, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of February 9, 2021, and the results of its operations and its cash flows for the period from February 3, 2021 (inception) through February 9, 2021, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

NOTES TO FINANCIAL STATEMENTS

NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

TortoiseEcofin Acquisition Corp. III (the “Company”) was incorporated as a Cayman Islands exempted company on February 3, 2021. The Company was formed for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

As of February 9, 2021, the Company had not commenced any operations. All activity for the period from February 3, 2021 (inception) through February 9, 2021 relates to the Company’s formation and the proposed initial public offering described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Proposed Public Offering (as defined below). The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is TortoiseEcofin Sponsor III LLC, a Cayman Islands limited liability company (the “Sponsor”), which is owned by TortoiseEcofin Investments, LLC, a Delaware limited liability company, and its consolidated subsidiaries (“Tortoise”) and the Company’s management (directly or indirectly, including through family trusts). The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a proposed public offering (the “Proposed Public Offering”) of 30,000,000 Class A ordinary shares (each, a “Public Share” and collectively, the “Public Shares”) at $10.00 per Public Share (or 34,500,000 Public Shares if the underwriters’ over-allotment option is exercised in full), which is discussed in Note 3, and the sale of 950,000 Class A ordinary shares (or 1,040,000 Class A ordinary shares if the underwriters’ over-allotment option is exercised in full) (each, a “Private Placement Share” and collectively, the “Private Placement Shares”), at a price of $10.00 per Private Placement Share in a private placement to Tortoise, that will close simultaneously with the Proposed Public Offering.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Public Offering and the sale of Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (as defined below) (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in Trust) at the time of the signing of the agreement to enter into the initial Business Combination, and a majority of the independent directors must approve such initial business combination(s). However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Upon the closing of the Proposed Public Offering, management will agree that an amount equal to at least $10.00 per Public Share sold in the Proposed Public Offering, including a portion of the proceeds from the sale of the Private Placement Shares, will be held in a trust account (“Trust Account”), located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and will be invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in money market fund meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company will provide the holders (the “Public Shareholders”) of Public Shares, with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated

F-7

NOTES TO FINANCIAL STATEMENTS

NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.)

to be $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). These Public Shares will be classified as temporary equity upon the completion of the Proposed Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and, only if a majority of the ordinary shares, represented in person or by proxy and entitled to vote thereon, voted at a shareholder meeting are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which the Company will adopt upon the consummation of the Proposed Public Offering (the “Amended and Restated Memorandum and Articles of Association”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or other reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or vote at all. If the Company seeks shareholder approval in connection with a Business Combination, the initial shareholders (as defined below) will agree to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Proposed Public Offering in favor of a Business Combination. Subsequent to the consummation of the Proposed Public Offering, the Company will adopt an insider trading policy which will require insiders to: (i) refrain from purchasing shares during certain blackout periods and when they are in possession of any material non-public information and (ii) to clear all trades with the Company’s legal counsel prior to execution. In addition, Tortoise and the initial shareholders will agree to waive their redemption rights with respect to their Founder Shares, Private Placement Shares and Public Shares in connection with the completion of a Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of its Business Combination and does not conduct redemptions in connection with its Business Combination pursuant to the tender offer rules, the Amended and Restated Memorandum and Articles of Association will provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 20% of the Class A ordinary shares sold in the Proposed Public Offering, without the prior consent of the Company.

The Company’s Sponsor, officers and directors (the “initial shareholders”) will agree not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (a) that would modify the substance or timing of the Company’s obligation to provide holders of its Public Shares the right to have their shares redeemed in connection with a Business Combination or to redeem 100% of the Company’s Public Shares if the Company does not complete its Business Combination within 24 months from the closing of the Proposed Public Offering, or 27 months from the closing of the Proposed Public Offering if the Company executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination within 24 months from the closing of the Proposed Public Offering but has not completed the initial Business Combination within such 24-month period (the “Combination Period”) or with respect to any other provision relating to the rights of Public Shareholders, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment.

If the Company has not completed a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the

NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS (cont.)

Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

Tortoise and the initial shareholders will agree to waive their liquidation rights with respect to the Founder Shares and Private Placement Shares held by them if the Company fails to complete a Business Combination within the Combination Period. However, if the initial shareholders acquire Public Shares in or after the Proposed Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters will agree to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor will agree to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per Public Share due to reductions in the value of the trust assets. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the underwriters of the Proposed Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”).

Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (excluding the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.

The Company does not have sufficient liquidity to meet its anticipated obligations over the next year from the date of issuance of these financial statements. In connection with the Company’s assessment of going concern considerations in accordance with FASB’s Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that the Company has access to funds from the Sponsor, and the Sponsor has the financial wherewithal to fund the Company, that are sufficient to fund the working capital needs of the Company until the earlier of the consummation of the Proposed Public Offering, at which time the Company will have sufficient working capital, and one year from the issuance of these financial statements.

NOTES TO FINANCIAL STATEMENTS

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Net Loss Per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the period. Weighted average ordinary shares were reduced for the effect of an aggregate of 1,125,000 Class B ordinary shares that are subject to forfeiture if the overallotment option is not exercised by the underwriters (Note 4). At February 9, 2021, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted loss per ordinary share is the same as basic loss per ordinary share for the period presented.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Company limit of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under the FASB ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet, primarily due to their short-term nature.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses

F-10

Table of Contents

TORTOISEECOFIN ACQUISITION CORP. III
NOTES TO FINANCIAL STATEMENTS

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (cont.)

during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Deferred Offering Costs Associated with the Proposed Public Offering

Deferred offering costs consisted of legal fees incurred through the balance sheet date that are directly related to the Proposed Public Offering and that will be charged to shareholder’s equity upon the completion of the Proposed Public Offering. Should the Proposed Public Offering prove to be unsuccessful, these deferred costs, as well as additional expenses to be incurred, will be charged to operations.

Income Taxes

FASB ASC 740, “Income Taxes,” prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities.

There were no unrecognized tax benefits as of February 9, 2021. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception. There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

NOTE 3 — PROPOSED PUBLIC OFFERING

Pursuant to the Proposed Public Offering, the Company intends to offer for sale 30,000,000 Public Shares (or 34,500,000 Public Shares if the underwriters’ over-allotment option is exercised in full) at a price of $10.00 per Public Share.

NOTE 4 — RELATED PARTY TRANSACTIONS

Founder Shares

On February 9, 2021, the Sponsor paid $25,000 to cover certain expenses on behalf of the Company in consideration of 7,187,500 Class B ordinary shares, par value $0.0001 (the “Founder Shares”). On February 18, 2021, the Company issued 1,437,500 Class B ordinary shares in connection with a share capitalization, resulting in an aggregate of 8,625,000 Founder Shares outstanding. All shares and associated amounts have been adjusted to reflect the share capitalization. The Sponsor agreed to forfeit up to 1,125,000 Founder Shares to the extent that the over-allotment option is not exercised in full by the underwriters, such number reflecting the adjustment by the share sub-division described above. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the underwriters so that the Founder Shares will represent 20.0% of the Company’s issued

F-11

NOTE 4 — RELATED PARTY TRANSACTIONS (cont.)

and outstanding ordinary shares (excluding the Private Placement Shares and assuming the initial shareholders do not purchase any Public Shares in the Proposed Public Offering) after the Proposed Public Offering. The initial shareholders will agree, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until the earlier to occur of: (x) one year after the completion of the initial Business Combination or earlier if, subsequent to the Business Combination, the last sale price of Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction after the initial Business Combination that results in all of the shareholders having the right to exchange their ordinary shares for cash, securities or other property.

Private Placement Shares

Tortoise will agree to purchase an aggregate of 950,000 Private Placement Shares (or 1,040,000 Private Placement Shares if the underwriters’ over-allotment option is exercised in full), at a price of $10.00 per Private Placement Share ($9.5 million in the aggregate, or $10.4 million if the underwriters’ over-allotment option is exercised in full) in a private placement that will occur simultaneously with the closing of the Proposed Public Offering. The Private Placement Shares will not be transferable or salable until 30 days after the completion of the initial Business Combination.

A portion of the proceeds from the Private Placement Shares will be added to the proceeds from the Proposed Public Offering to be held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Shares held in the trust account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Shares will be worthless.

Tortoise, the Sponsor and the Company’s officers and directors will agree, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Shares until 30 days after the completion of the initial Business Combination.

Related Party Loans

On February 3, 2021, the Sponsor agreed to loan the Company an aggregate of up to $600,000 to cover expenses related to the Proposed Public Offering pursuant to a promissory note (the “Note”). This loan is non-interest bearing and payable on the earlier of (x) the date that is 180 days following the date of the Note, or August 2, 2021, and (y) the consummation of the Proposed Public Offering. As of February 9, 2021, the Company has not borrowed any amount under the Note. Subsequent to February 9, 2021, the Company borrowed approximately $118,000 under the Note.

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company may repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans may be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into shares of the post Business Combination entity at a price of $10.00 per share. The shares would be identical to the Private Placement Shares. As of February 9, 2021, the Company had no outstanding borrowings under the Working Capital Loans.

NOTE 4 — RELATED PARTY TRANSACTIONS (cont.)

Administrative Services Agreement

The Company will enter into an agreement that will provide that, commencing on the date that the Company’s securities are first listed on the NYSE through the earlier of consummation of the initial Business Combination and the liquidation, the Company will pay an affiliate of the Sponsor $10,000 per month for office space, utilities, secretarial support and administrative services.

In addition, the Sponsor, executive officers and directors, or any of their respective affiliates will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential partner businesses and performing due diligence on suitable Business Combinations. The Company’s audit committee will review on a quarterly basis all payments that were made by the Company to the Sponsor, executive officers or directors, or the Company’s or their affiliates. Any such payments prior to an initial Business Combination will be made using funds held outside the Trust Account.

NOTE 5 — COMMITMENTS AND CONTINGENCIES

Registration Rights

The holders of Founder Shares, Private Placement Shares and any shares that may be issued upon conversion of working capital loans (and any Class A ordinary shares issuable upon conversion of the Founder Shares), and any Class A ordinary shares held by the Company’s initial shareholders and Tortoise at the completion of this offering or acquired prior to or in connection with the initial Business Combination, will be entitled to registration rights pursuant to a registration rights agreement to be signed prior to or on the effective date of the Proposed Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the Company’s completion of its Business Combination. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period, which occurs (i) in the case of the Founder Shares, in accordance with the letter agreement the Company’s initial shareholders entered into and (ii) in the case of the Private Placement Shares, 30 days after the completion of the Company’ s Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

The Company will grant the underwriters a 45-day option from the date of the final prospectus relating to the Proposed Public Offering to purchase up to 4,500,000 additional Public Shares to cover over-allotments, if any, at the Proposed Public Offering price less the underwriting discounts and commissions.

The underwriters will be entitled to underwriting commissions of $0.20 per Public Share, or $6.0 million in the aggregate (or $6.9 million in the aggregate if the underwriters’ over-allotment option is exercised in full), payable upon the closing of the Proposed Public Offering. In addition, $0.35 per Public Share, or $10.5 million in the aggregate (or approximately $12.1 million in the aggregate if the underwriters’ over-allotment option is exercised in full) will be payable to the underwriters for deferred underwriting commissions. The deferred commissions will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations, the proposed initial public offering and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

NOTE 6 — SHAREHOLDER’S EQUITY

Preference Shares — The Company is authorized to issue 1,000,000 preference shares with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of February 9, 2021, there were no preference shares issued or outstanding.

Class A Ordinary Shares — The Company is authorized to issue 200,000,000 Class A ordinary shares with a par value of $0.0001 per share. As of February 9, 2021, there were no Class A ordinary shares issued or outstanding.

Class B Ordinary Shares — The Company is authorized to issue 20,000,000 Class B ordinary shares with a par value of $0.0001 per share. In February 2021, the Company issued 7,187,500 Class B ordinary shares to the Sponsor in exchange for the payment of $25,000 of expenses, or approximately $0.003 per share. On February 18, 2021, the Company issued 1,437,500 Class B ordinary shares to the Sponsor in connection with a share capitalization, resulting in the Sponsor holding an aggregate of 8,625,000 Founder Shares. The shares have been retroactively restated to reflect this share capitalization. Of the 8,625,000 Class B ordinary shares outstanding, an aggregate of up to 1,125,000 shares are subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriters’ over-allotment option is not exercised in full or in part, so that the initial shareholders will collectively own 20% of the Company’s issued and outstanding ordinary shares (excluding the Private Placement Shares and assuming the initial shareholders do not purchase any shares in the Proposed Public Offering) (See Note 4).

Holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the shareholders, except that in respect of any vote or votes to continue the company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the company in such other jurisdiction), holders of Class B ordinary shares will have ten votes per share and holders of Class A ordinary shares will have one vote per share, and except as required by law or stock exchange rule; provided that only holders of the Class B ordinary shares have the right to vote on the election of the Company’s directors (and may also remove a member of the board of directors for any reason) prior to the initial Business Combination.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of the initial Business Combination on a one-for-one basis, subject to adjustment for share sub-divisions, share dividends, reorganizations, recapitalizations and the like and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Proposed Public Offering and related to the closing of the initial Business Combination, the ratio at which Class B ordinary shares shall convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all ordinary shares outstanding upon the completion of the Proposed Public Offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination and the Private Placement Shares). In no event will the Class B ordinary shares convert into Class A ordinary shares at a rate of less than one-to-one.

NOTE 7 — SUBSEQUENT EVENTS

On February 18, 2021, the Company issued 1,437,500 Class B ordinary shares in connection with a share capitalization, resulting in an aggregate of 8,625,000 Founder Shares outstanding. All shares and associated amounts have been adjusted to reflect the share capitalization.

Subsequent to February 9, 2021, the Company borrowed approximately $118,000 under the Note.

Management has evaluated subsequent events to determine if events or transactions that occurred through April 9, 2021, the date the financial statements were available for issuance, require potential adjustment to or disclosure in the financial statements and has concluded that, except as noted above, no other events that would require recognition or disclosure have been recognized or disclosed.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 13. Other Expenses of Issuance and Distribution.

The estimated expenses payable by us in connection with the offering described in this registration statement (other than the underwriting discounts and commissions) will be as follows:

SEC expenses	$	37,640
FINRA expenses		52,250
Accounting and bookkeeping fees and expenses		45,000
Printing and engraving expenses		60,000
Travel and road show expenses		20,000
Directors’ & Officers’ liability insurance premiums(1)		1,500,000
Legal fees and expenses		350,000
NYSE listing and filing fees		85,000
Miscellaneous(2)		350,110
Total	$	2,500,000

____________

(1) This amount represents the approximate amount of annual director and officer liability insurance premiums we anticipate paying following the completion of our initial public offering and until we complete a business combination.

(2) This amount represents additional expenses that may be incurred by us in connection with the offering over and above those specifically listed above, including distribution and mailing costs.

Item 14. Indemnification of Directors and Officers.

Cayman Islands law does not limit the extent to which a company’s memorandum and 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 amended and restated memorandum and articles of association will provide for indemnification of our officers and directors to the maximum extent permitted by law, including for any liability incurred in their capacities as such, except through their own actual fraud, willful default or willful neglect. We will enter into agreements with our directors and officers to provide contractual indemnification in addition to the indemnification provided for in our amended and restated memorandum and articles of association. We expect to purchase a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

Our officers and directors have agreed to waive any right, title, interest or claim of any kind in or to any monies in the trust account, and have agreed to waive any right, title, interest or claim of any kind they may have in the future as a result of, or arising out of, any services provided to us and will not seek recourse against the trust account for any reason whatsoever (except to the extent they are entitled to funds from the trust account due to their ownership of public shares). Accordingly, any indemnification provided will only be able to be satisfied by us if (i) we have sufficient funds outside of the trust account or (ii) we consummate an initial business combination.

Item 15. Recent Sales of Unregistered Securities.

In February 2021, 7,187,500 of our Class B ordinary shares were issued to our sponsor in exchange for the payment of $25,000 of expenses on our behalf, or approximately $0.003 per share. On February 18, 2021, we issued 1,437,500 Class B ordinary shares to our sponsor in connection with a share capitalization, resulting in our sponsor holding an aggregate of 8,625,000 founder shares. The number of founder shares was determined based on the

II-1

Table of Contents

expectation that the founder shares would represent 20% of the outstanding shares after this offering (excluding the private placement shares). Such securities were issued in connection with our organization pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

Our sponsor is an accredited investor for purposes of Rule 501 of Regulation D under the Securities Act. The sole business of our sponsor is to act as our sponsor in connection with this offering.

In addition, Tortoise has committed, pursuant to a written agreement, to purchase from us an aggregate of 950,000 (or 1,040,000 if the underwriters’ over-allotment option is exercised in full) private placement shares at $10.00 per share (for an aggregate purchase price of approximately $9,500,000 (or approximately $10,400,000 if the underwriters’ over-allotment option is exercised in full)). These purchases will take place on a private placement basis simultaneously with the completion of our initial public offering. These issuances will be made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

No underwriting discounts or commissions were paid with respect to such sales.

Item 17. Undertakings.

(a) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(b) The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
