This investor presentation supersedes all previous investor presentations delivered in connection with the Business Combination. You should only refer to the information in this version of the investor presentation. Forward-Looking Statements Disclaimer Certain statements in this Presentation may be considered forward-looking statements. Forward-looking statements generally relate to future events or SPAC’s or the Company’s future financial or operating performance. For example, projections of future Revenue and Adjusted EBITDA and other metrics are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may”, “should”, “expect”, “intend”, “will”, “estimate”, “anticipate”, “believe”, “predict”, “potential” or “continue”, or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by SPAC and its management, and the Company and its management, as the case may be, are inherently uncertain and are inherently subject to risks, variability and contingencies, many of which are beyond the Company’s control. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of negotiations and any subsequent definitive agreements with respect to the Business Combination; (2) the outcome of any legal proceedings that may be instituted against SPAC, the combined company or others following the announcement of the Business Combination and any definitive agreements with respect thereto; (3) the inability to complete the Business Combination due to the failure to obtain approval of the shareholders of SPAC, to obtain financing to complete the Business Combination or to satisfy other conditions to closing; (4) changes to the proposed structure of the Business Combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the Business Combination; (5) the ability to meet stock exchange listing standards following the consummation of the Business Combination; (6) the risk that the Business Combination disrupts current plans and operations of the Company as a result of the announcement and consummation of the Business Combination; (7) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain key relationships and retain its management and key employees; (8) costs related to the Business Combination; (9) changes in applicable laws or regulations; (10) the possibility that the Company or the combined company may be adversely affected by other economic, business, and/or competitive factors; (11) the Company’s estimates of expenses and profitability; and (12) other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in SPAC’s final prospectus relating to its initial public offering dated September 16, 2020, in the registration statement on Form F-4, initially filed by the Company with the SEC on December 20, 2021 (as amended or supplemented through the date hereof, the Registration Statement ) or in other documents filed by SPAC or the Company with the SEC. There may be additional risks that neither SPAC nor the Company presently know or that SPAC and the Company currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. Nothing in this Presentation should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Neither SPAC nor the Company undertakes any duty to update these forward-looking statements or to inform the recipient of any matters of which any of them becomes aware of which may affect any matter referred to in this Presentation. The Company and SPAC disclaim any and all liability for any loss or damage (whether foreseeable or not) suffered or incurred by any person or entity as a result of anything contained or omitted from this Presentation and such liability is expressly disclaimed. The recipient agrees that it shall not seek to sue or otherwise hold the Company, SPAC or any of their respective directors, officers, employees, affiliates, agents, advisors or representatives liable in any respect for the provision of this Presentation, the information contained in this Presentation, or the omission of any information from this Presentation. Only those particular representations and warranties of the Company or SPAC made in a definitive written agreement regarding the transaction (which will not contain any representation or warranty relating to this Presentation) when and if executed, and subject to such limitations and restrictions as specified therein, shall have any legal effect. Non-GAAP Financial Measures This Presentation includes projections of certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, Adjusted EBITDA and certain ratios and other metrics derived therefrom. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing the Company’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that the Company’s presentation of these measures may not be comparable to similarly-titled measures used by other companies. The Company believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. The Company believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing the Company’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP financial measures is included. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results.

Use of Projections This Presentation contains financial forecasts with respect to the Company’s projected financial results, including Revenue and Adjusted EBITDA, for the Company's fiscal years 2021, 2022, 2025 and from 2025-2030. The Company's independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. Neither of the placement agents, in any capacity, has warranted or warrants the accuracy, reliability, appropriateness or completeness of the prospective financial information contained herein to anyone. Industry and Market Data This presentation also contains estimates and other statistical data made by independent parties and by the Company relating to market size and growth and other data about the Company’s industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions, and estimates of the future performance of the markets in which the Company operates are necessarily subject to a high degree of uncertainty and risk. This presentation concerns drugs that are in development and which have not yet been approved for marketing by the U.S. Food and Drug Administration (FDA). No representation is made as to the safety or effectiveness of any of the products in development, nor for any products which may have applications pending before the FDA.

APPENDIX BIOSIMILAR BACKGROUND INFORMATION

Biosimilars Are Highly Comparable To Biologics, An Important Class Of Medicine BIOLOGIC BIOSIMILAR Development Path • Proof of quality and analytical similarity • Pharmacokinetic bioequivalence • Clinical data showing comparable safety and efficacy • Support pharmacy substitution and interchangeability in US • Large, complex molecules, that are used to diagnose, • Highly similar to their authorized, originator (reference) prevent, treat, and cure diseases and medical biologic products, with no clinically meaningful differences conditions • Typically have the same amino acid sequence • May be produced through biotechnology in a living • Held to same high-quality standards as reference products system, such as an animal cell, often more difficult to • Must demonstrate totality of evidence with respect to characterize than small molecule drugs physiochemical characteristics, biologic activity, pharmacokinetics, and clinical safety and efficacy • Rigorous regulatory approval process, with a stepwise approach • Enables expanded patient access and lower costs to biologics 49 Source: Weise M, et al. Nat Biotechnol. 2011;29(8):690-693..

Regulatory Definition Of Biosimilars A biosimilar is a biologic medicinal product that contains a version of the active substance of an already authorized original biologic medicinal product (reference medicinal product). A biosimilar demonstrates similarity to the reference medicinal product in terms of quality characteristics, biologic activity, safety, and efficacy based on a comprehensive comparability exercise. Committee for Medicinal Products for Human Use. Guideline on similar biologic medicinal products. CHMP/437/04 Rev 1, 23 October 2014 Biosimilarity means “that the biologic product is highly similar to the reference product notwithstanding minor differences in clinically inactive components” and that “there are no clinically meaningful differences between the biologic product and the reference product in terms of the safety, purity, and potency of the product” US Food and Drug Administration. Guidance for Industry. Biosimilars: questions and answers regarding implementation of the biopharmaceutical Price Competition and Innovation Act of 2009. Department of Health & Human Services, 2012. 50

Interchangeability May Enhance Speed Of Biosimilar Adoption And Growth › Interchangeable designation in the US allows for substitution without (1) authorization by the prescribing physician ‒ Pharmacists can substitute the interchangeable biosimilar for the originator without approval ‒ Interchangeability is most important for pharmacy-distributed medicines, e.g. for the treatment of chronic diseases › Interchangeable biosimilars must produce the same clinical result as the originator (branded biologic) without additional safety risk or loss of efficacy from switching ‒ Designation usually requires an additional clinical study › First approved IC biosimilar to reference product is eligible for a period of exclusivity as to other subsequently approved IC biosimilars to the same reference product › Alvotech plans to pursue interchangeability designations where appropriate for its development programs 52 Source: fda.gov 1.

Carefully consider the following risk factors, among others that will be contained in (or incorporated by reference into) the proxy statement/prospectus, related to Alvotech’s business, reputation, financial condition, results of operations, revenue and the future prospects if the business combination is consummated. • Significant losses since inception and anticipation of losses over the near term. • Never generated any revenue from product sales and may never be profitable. • Prior to the consummation of the Business Combination, and even after the Business Combination is consummated, Alvotech may need to raise substantial additional funding from shareholders or third parties. Alvotech’s management has determined that there is a material uncertainty that may cast significant doubt about the Group’s ability to continue as a going concern. • No assurance that product candidates will receive regulatory approval on expected timelines or at all. • Biosimilar product candidates may not meet regulatory authority requirements for approval as a biosimilar product or as an interchangeable product in any jurisdiction. • Regulatory approval processes are lengthy, time consuming and inherently unpredictable and may be delayed for reasons beyond our control, including, but not limited to, COVID-19 potentially resulting in delays in conducting FDA and other regulatory inspections of production facilities and, therefore, approval. • Substantial delays in analytical characterization and clinical studies or failure to demonstrate safety and efficacy of product candidates. Risk Factors • Successful or timely completion of clinical development may be prevented by regulatory inspection of clinical study operations or study sites or as a result of adverse events reported during a clinical trial. • Product candidates may cause undesirable side effects or have other properties that could result in significant negative consequences following marketing approval, if granted. • Other biosimilars may be approved and successfully commercialized before Alvotech’s product candidates. • Failure to obtain regulatory approval in any targeted regulatory jurisdiction. • Adverse events involving a reference product may adversely affect Alvotech’s business. • Inability to retain key members of management or recruit additional management, clinical and scientific personnel. • Reliance on third parties to conduct nonclinical and clinical studies and manufacture nonclinical and clinical supplies of product candidates and to store critical components of product candidates. • Dependence on third party collaborators for the commercialization of product candidates in certain major markets. • Adverse developments affecting the manufacturing operations of Alvotech’s product candidates. • May not realize the benefits expected through the CCHT joint venture. • Reliance on third parties requires Alvotech to share trade secrets, which increases the possibility that a competitor will discover them. • If approved, product candidates will face significant competition from the reference products and other pharmaceuticals approved for the same indication. • Rapidly technological changes in the industry. • Commercial success of any current or future product candidate will depend upon the degree of market acceptance. • Third-party claims of intellectual property infringement or claims of reference product exclusivity may prevent or delay development and commercialization efforts. • Potential involvement in lawsuits to protect or enforce Alvotech’s patents. • Inability to protect intellectual property rights throughout the world. • Failure to identify, develop or commercialize additional product candidates. • Healthcare legislative reform measures may have a material adverse effect. • Exposure to business, regulatory, political, operational, financial and economic risks associated with conducting business globally, including but not limited to, the Russia-Ukraine conflict. • The ability to consummate the business combination, and the operations following the business combination, may be materially adversely affected by the recent coronavirus (COVID-19) pandemic. 80
