Risk Factors Risks Related to APRINOIA’s Limited Operating History, Financial Position and Need for Additional Capital APRINOIA is a clinical-stage biotechnology company with a limited operating history and faces significant challenges and expenses as it builds its capabilities and develops its pipeline of diagnostic and therapeutic product candidates. APRINOIA has incurred net losses since its inception and anticipates that it will continue to incur significant losses for the foreseeable future. APRINOIA has never generated any revenue from product sales and may never be profitable. APRINOIA may need to acquire funding from time to time to complete the development and any commercialization of its product candidates, which may not be available on acceptable terms, or at all. If APRINOIA is unable to raise capital when needed, it may be forced to delay, reduce or eliminate certain of its product development programs or other operations. Raising additional capital may cause dilution to the interests of APRINOIA’s shareholders, restrict APRINOIA’s operations or require it to relinquish rights to its technologies or product candidates. APRINOIA is heavily dependent on the success of its lead diagnostic product candidate 18F-APN-1607 (tau PET tracer), and to a lesser extent APN-mAb005, its anti-tau antibody candidate, and degrader programs, all of which are currently or expected to be in clinical development. If APRINOIA’s clinical trials are unsuccessful, it or its licensing or collaboration partners do not obtain regulatory approval or it is unable to commercialize 18F-APN-1607, APN-mAb005, degraders, or it experiences significant delays in doing so, its business, financial condition and results of operations will be materially adversely affected. APRINOIA operates in highly competitive and rapidly changing industries. Its competitors are evaluating diagnostic product candidates in the same indication as its lead diagnostic product candidate, 18F-APN-1607 (tau PET tracer), and could enter the market with competing products of its product candidates, which may result in a material decline in sales of affected product candidates. Even if APRINIOA successfully obtains regulatory approvals for its product candidates, the products may not gain market acceptance, in which case APRINOIA may not be able to generate product revenues, which will materially adversely affect its business, financial condition and results of operations. Results of preclinical studies or early phases of clinical trials may not be predictive of future study results. Clinical trials are difficult to design and implement, involve uncertain outcomes and may not be successful. APRINOIA depends on enrollment of patients in its clinical trials for its product candidates. If it encounters difficulties enrolling patients in its clinical trials, its clinical development activities could be delayed or otherwise adversely affected. If serious adverse, undesirable or unacceptable side effects are identified during the development of APRINOIA’s product candidates or following approval, if any, APRINOIA may need to abandon its development of such product candidates, the commercial profile of any approved label may be limited, or APRINOIA may be subject to other significant negative consequences following marketing approval, if any. If the clinical trials of any of APRINOIA’s product candidates fail to demonstrate safety and efficacy to the satisfaction of the FDA, the NMPA or other regulatory authorities, or do not otherwise produce favorable results, APRINOIA may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of its product candidates. Preliminary, interim and topline data from APRINOIA’s clinical trials that it may announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data. APRINOIA’s preclinical programs may experience delays or may never advance to clinical trials, which would adversely affect APRINOIA’s ability to obtain regulatory approvals or commercialize these product candidates on a timely basis or at all, which would have an adverse effect on APRINOIA’s business. APRINOIA may not be successful in its efforts to extend its pipeline of product candidates, including identifying or discovering additional product candidates in the future. Due to APRINOIA’s limited resources and access to capital, APRINOIA must prioritize development of certain product candidates. Therefore, it may fail to capitalize on product candidates or indications that may be more profitable or have a greater likelihood of success. Changes in methods of product candidate manufacturing may result in additional costs or delays. APRINOIA may seek to obtain orphan drug designation for certain of its product candidates such as 18F-APN-1607. Orphan drug designation may not ensure that APRINOIA will enjoy market exclusivity in a particular market, and if it fails to obtain or maintain orphan drug exclusivity for such product candidates, it may be subject to earlier competition and its potential revenue will be reduced.
Risk Factors Risks Related to APRINOIA’s Business Operations As a company currently with substantial operations outside of the United States, APRINOIA’s business is subject to economic, political, regulatory and other risks associated with international operations. APRINOIA’s future growth and ability to compete depends on retaining its key personnel and recruiting additional qualified personnel. APRINOIA is a fast-growing emerging company and expects to expand its development, and regulatory capabilities, and as a result, it may encounter difficulties in managing its growth, which could disrupt our operations. The COVID-19 pandemic could adversely impact APRINOIA’s business, including its clinical trials. APRINOIA has granted, and may continue to grant, options and other types of awards under its share incentive plans, which may result in significant share-based non-cash compensation expenses and you will incur immediate and substantial dilution. APRINOIA’s research and development activities could be affected or delayed because of possible restrictions on animal testing. APRINOIA’s information technology systems could face serious disruptions that could adversely affect its business. APRINOIA is or may become subject to a variety of privacy and data security laws, policies and contractual obligations, and its failure or failure of its third-party vendors, collaborators, contractors or consultants to comply with them could harm APRINOIA’s business. Risks Related to APRINOIA’s Relationships with Third Parties If APRINOIA fails to maintain its relationships with its current or future business and licensing partners, its business, commercialization prospects and financial condition may be materially adversely affected. APRINOIA may seek to form additional strategic alliances in the future with respect to its product candidates, and if it does not realize the benefits of such alliances, its business, financial condition, commercialization prospects and results of operations may be materially adversely affected. APRINOIA relies on third parties to conduct its nonclinical and clinical studies and perform other tasks for it. If these third parties do not successfully carry out their contractual duties, meet expected deadlines, or comply with regulatory requirements, APRINOIA may not be able to obtain regulatory approval for or commercialize our product candidates and its business could be substantially harmed. APRINOIA currently relies on third-party suppliers for the manufacturing and supply of certain of its product candidates for use in preclinical testing and clinical trials or for commercial use in the future, which supply could become limited or interrupted or may not be of satisfactory quality and quantity. Our dependence on these third parties may also impair the advancement of our research and development programs and the development of our product candidates. If APRINOIA engages in future acquisitions or strategic collaborations, this may increase its capital requirements, dilute its shareholders, cause it to incur debt or assume contingent liabilities and subject it to other risks. Risks Related to the Commercialization of APRINOIA’s Product Candidates If APRINOIA is unable to establish sales, marketing and distribution capabilities for its product candidates, or enter into sales, marketing and distribution agreements with third parties, it may not be successful in commercializing its product candidates, if and when they are approved. The successful commercialization of its product candidates will depend in part on the extent to which governmental authorities and health insurers establish adequate coverage and reimbursement levels and pricing policies. APRINOIA has never commercialized a product candidate before, which may make it difficult to evaluate the prospects for its future viability, and may lack the necessary expertise, personnel and resources to successfully commercialize its product candidates on its own or together with suitable partners. APRINOIA’s projections regarding the size of the addressable market of its product candidates may be incorrect. In addition, the market opportunities for its diagnostic product candidates may be limited, as the relevant effective treatments for those patients may be unavailable. APRINOIA may become exposed to costly and damaging liability claims, either when testing its product candidates in the clinic or at the commercial stage, which may limit commercialization of any product candidates that it may develop, and its product liability insurance may not cover all damages from such claims.
Risk Factors Risks Related to Regulatory Approval of APRINOIA’s Product Candidates and Other Legal Compliance Matters All material aspects of the research, development, manufacturing and commercialization of pharmaceutical products are heavily regulated, and APRINOIA may face difficulties in complying with or be unable to comply with such regulations, which could have a material adverse effect on APRINOIA’s business. The approval processes of regulatory authorities in the United States and other applicable jurisdictions are lengthy, time-consuming and inherently unpredictable. If APRINOIA is ultimately unable to obtain regulatory approval for APRINOIA’s product candidates, APRINOIA’s business will be substantially harmed. Even if APRINOIA completes the necessary preclinical studies and clinical trials, the regulatory approval process is expensive, time-consuming and uncertain and may prevent APRINOIA from obtaining approvals for the commercialization of some or all of its product candidates. As a result, it cannot predict when or if, and in which territories, it will obtain marketing approval to commercialize product candidates. APRINOIA obtaining and maintaining regulatory approval of its product candidates in one jurisdiction does not mean that it will be successful in obtaining regulatory approval of its product candidates in other jurisdictions. APRINOIA is currently conducting and may in the future conduct clinical trials for its product candidates outside the United States, and the FDA and comparable foreign regulatory authorities may not accept data from such trials. Any product candidate for which APRINOIA obtains marketing approval may be subject to post-approval regulatory obligations and continued regulatory review, which may result in significant additional expense, and APRINOIA may be subject to penalties if it fails to comply with regulatory requirements or experience unanticipated problems with its diagnostic and therapeutic product candidates. APRINOIA’s employees, independent contractors, CMOs, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements. Recently enacted and future legislation may increase the difficulty and cost for APRINOIA to obtain regulatory approval of and commercialize its diagnostic and therapeutic candidates and affect the prices it may obtain. APRINOIA is subject to certain foreign export and import controls, sanctions, embargoes, anti-corruption laws, and anti-money laundering laws and regulations. Any violation of such laws and regulations may subject it to criminal liability and other serious consequences. If APRINOIA fails to comply with environmental, health and safety and social impact assessment laws and regulations, APRINOIA could become subject to fines or penalties or incur costs that could harm its business. APRINOIA’s business operations and relationships with healthcare professionals, consultants, customers and third-party payors in the United States and elsewhere are subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, physician payment transparency, health information privacy and security and other healthcare laws and regulations, which could expose it to substantial penalties.
Risk Factors Risks Related to APRINOIA’s Intellectual Property APRINOIA may not have sufficient patent terms to effectively protect its future approved product candidates and business. If APRINOIA is or its licensing or collaboration partners are unable to obtain, maintain, defend and enforce patent and other intellectual property rights for its technologies and product candidates, or if the scope of the patent and other intellectual property rights obtained is not sufficiently broad, APRINOIA’s competitors and other third parties could develop and commercialize technology and biologics similar or identical to APRINOIA’s, and its ability to successfully commercialize its technology and product candidates may be impaired. APRINOIA or its licensing or collaboration partners may become subject to intellectual property-related litigation or other proceedings to protect or enforce APRINOIA’s patents or the patents of its licensors or collaborators, any of which could be expensive, time consuming, and unsuccessful, and may ultimately result in APRINOIA’s loss of ownership of intellectual property. APRINOIA may be subject to claims challenging the inventorship of its patents and other intellectual property. APRINOIA may need to license intellectual property from third parties, and such licenses may not be available or may not be available on commercially reasonable terms or at all. Any trademarks APRINOIA may obtain may be infringed or successfully challenged, resulting in harm to its business. Changes in patent law in the United States and other applicable jurisdictions could diminish the value of patents in general, thereby impairing APRINOIA’s ability to protect its future approved product candidates. APRINOIA may not be able to protect its intellectual property rights throughout the world. Confidentiality agreements with employees and third parties may not prevent unauthorized disclosure of trade secrets and other proprietary information. Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and APRINOIA’s patent protection could be reduced or eliminated for non-compliance with these requirements. Risks Related to ROSS, the Business Combination and PubCo’s Securities Following Consummation of the Business Combination Ross Holding Company LLC (the “Sponsor”) has agreed to vote in favor of the Business Combination, regardless of how ROSS’s public shareholders vote which will increase the likelihood that ROSS will receive the requisite shareholder approval for the Business Combination even if a substantial number of public shares are voted against the Business Combination. The Sponsor and directors and officers of ROSS have interests in the Business Combination which may be different from or in addition to (and which may conflict with) the interests of its shareholders. The Sponsor, and ROSS’s directors, officers, advisors and their affiliates may, subject to compliance with applicable law, enter into certain transactions, including purchasing shares or warrants from public shareholders, with the purpose of decreasing the number of redemptions, which may reduce the public “float” of its securities. There can be no assurance that the shares issued in connection with the Business Combination will be approved for listing on Nasdaq or the NYSE or that the combined company will be able to comply with the continued listing standards of Nasdaq or the NYSE, as applicable, which could limit investors’ ability to make transactions in the combined company’s securities and subject the combined company to additional trading restrictions. The ability of ROSS shareholders to exercise redemption rights with respect to a large number of ROSS shares could deplete the ROSS trust account prior to the Business Combination and thereby diminish the amount of working capital of the combined company. The grant and future exercise of registration rights may adversely affect the market price of PubCo ordinary shares upon consummation of the Business Combination. The ROSS board of directors did not obtain a third-party valuation in determining whether or not to pursue the Business Combination. The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Business Combination agreement may be terminated in accordance with its terms and the Business Combination may not be complete. Legal proceedings in connection with the Business Combination, the outcomes of which are uncertain, could delay or prevent the completion of the Business Combination. Each of APRINOIA and ROSS will incur significant transaction costs in connection with the Business Combination. If ROSS is unable to complete the Business Combination with APRINOIA or another business combination by March 16, 2023 (or such later date as may be agreed by ROSS shareholders), ROSS will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding public shares and, subject to the approval of its remaining shareholders and its board of directors, dissolving and liquidating. If ROSS were deemed an “investment company” under the Investment Company Act, it may be required to institute burdensome compliance requirements and its activities may be restricted, which may make it difficult to complete the Business Combination. If the benefits of the Business Combination do not meet the expectations of investors or securities analysts, the market price of PubCo ordinary shares may decline. An active trading market for PubCo’s ordinary shares may not be available on a consistent basis to provide shareholders with adequate liquidity. The share price may be volatile, and shareholders could lose a significant part of their investment.

Our PET Tracer, 18F-APN-1607 Clinically validated in >2,600 subjects; Phase 3 in China and Phase 2 in the US Specific, with no MAO-B binding Believed to be the only tau tracer that binds 4R tau, so it can be used in preclinical models, e.g., rTg4510 mouse model Only tau tracer with CryoEM structure of APN-1607 bound to AD tau available, allowing further structure-based drug design2 Only tau tracer with wide utility in AD and many non-AD tauopathies, including PSP, CBS, bvFTD, PNFA, & Pick’s Biogen and Bristol Myers-Squibb have used APN-1607 in clinical studies 18F-flortaucipir (Tauvid®, Lilly) FDA-approved in 2020 Off-target binding (MAO-B) Poor early detection of AD Limited use in non-AD tauopathies Challenges with Current PET Tracers1 18F-PI-2620 (Life Molecular Imaging) 18F-RO-948 (Roche) Reduced off-target binding, but limitations remain due to similar chemistry as Tauvid® 18F-MK-6240 (Merck) 18F-PI-2620 (Life Molecular Imaging) Being investigated for 4R tauopathies, however data is inconsistent only useful in AD useful in all tauopathies
