GENERAL INFORMATION

Unless otherwise indicated or the context otherwise requires, all references in this Annual Report on Form 10-K (the “Annual Report”) to the terms “Quoin,” “Quoin Ltd.,” the “Company,” “us,” “we”, “our” and the “Registrant” refer to Quoin Pharmaceuticals Ltd., an Israeli company, and its consolidated subsidiaries. In this Annual Report, the U.S. Securities and Exchange Commission is referred to as the “SEC”, the Securities Act of 1933, as amended, is referred to as the “Securities Act” and the Securities Exchange Act of 1934, as amended, is referred to as the “Exchange Act.”

Effective April 9, 2025, the ratio of American Depositary Shares (“ADSs”) evidencing our ordinary shares, no par value per share (“Ordinary Shares”), changed from 1 ADS representing one (1) Ordinary Share to 1 ADS representing thirty - five (35) Ordinary Shares (the “Ratio Change”), which resulted in a 1 - for - 35 reverse split of the issued and outstanding ADSs (the “Reverse Split”). Our Ordinary Shares were not affected by this adjustment. Except as specifically provided, ADSs and related option, warrant, purchase price and exercise price information presented in this Annual Report, including our consolidated financial statements and the related notes, has been retroactively adjusted to reflect the Ratio Change and the Reverse Split.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain information included in this Annual Report may be deemed to be “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 and other securities laws. Forward-looking statements are often characterized by the use of forward-looking terminology such as “may,” “will,” “expect,” “anticipate,” “estimate,” “continue,” “believe,” “should,” “intend,” “project” or other similar words, but are not the only way these statements are identified.

These forward-looking statements may include, but are not limited to, statements relating to our objectives, plans and strategies, statements that contain projections of results of operations or of financial condition, expected capital needs and expenses, statements relating to the research, development, completion and use of our products, and all statements (other than statements of historical facts) that address activities, events or developments that we intend, expect, project, believe or anticipate will or may occur in the future.

Forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties. We have based these forward-looking statements on assumptions and assessments made by our management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate.

Important factors that could cause actual results, developments and business decisions to differ materially from those anticipated in these forward-looking statements include, among other things:

●our limited operating history and the difficulties encountered by a small developing company;
●our history of losses and inability to fund our business from operations may require us in the future to obtain additional capital the terms of which may not be on acceptable terms, or at all;
●we must raise additional capital to fund our operations in order to continue as a going concern;
●our lack of revenue and potential inability to be profitable;
●uncertainties of cash flows and inability to meet working capital needs;
●the terms of our October 2025 private placement may make it difficult for us to procure additional financing;
●our ability to obtain regulatory approvals;
●our ability to generate favorable pre-clinical and clinical trial results;
●our ability to identify and develop potential product candidates;
●additional costs or delays associated with unsuccessful clinical trials;
●the inability to predict the timing of revenue from sales of a future product;
●the extensive regulatory requirements and future developmental and regulatory challenges we will still face even if we obtain approval for a product candidate;
●our ability to maintain orphan drug designation or obtain orphan drug exclusivity for our product candidates;
●the potential oversight of programs or product candidates that may be more profitable or more successful;
●our manufacturing processes may not be validated and our methodology may not be accepted by the scientific community;
●the ability to conduct clinical trials, because of difficulties enrolling patients or other reasons;
●the costs and demands of being a publicly traded company may harm our business;
●potential adverse effects resulting from failure to maintain effective internal controls;
●our ability to comply with the applicable continued listing requirements of Nasdaq;
●the potential negative impact on our securities price and trading volume if securities or industry analysts do not publish reports about us or if they adversely change their recommendations about our business;
●the potential volatility of the market price for our ADSs;
●the potential dilution of our shareholders’ potential ownership due to future issuances of share capital;
●the requirement for holders of ADSs to act through the depositary to exercise their rights;
●the potential limitations on ADS holders with respect to the transfer of their ADSs;
●the risks of securities class action litigation; and
●other risks and uncertainties, including those listed under Part I, Item 1A of this Annual Report titled “Risk Factors.”

You are urged to carefully review and consider the various disclosures made throughout this Annual Report which are designed to advise interested parties of the risks and factors that may affect our business, financial condition, results of operations and prospects.

You should not put undue reliance on any forward-looking statements. Although the forward-looking statements in this Annual Report are based on our beliefs, assumptions and expectations, taking into account all information currently available to us, we cannot guarantee future transactions, results, performance, achievements or outcomes. No assurance can be made that the expectations reflected in our forward-looking statements will be attained, or that deviations from them will not be material and adverse. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

In addition, certain sections of this Annual Report contain information obtained from independent industry sources and other sources that we have not independently verified.

SUMMARY OF RISK FACTORS

An investment in our Company is subject to a number of risks. Set forth below is a high-level summary of some, but not all, of these risks. You should review and consider carefully the risks and uncertainties described in more detail in “Part I, Item 1A. Risk Factors” of this Annual Report, which includes a more complete discussion of the risks summarized below as well as a discussion of other risks related to our business and an investment in our securities.

Risks Related to Our Financial Position and Capital Requirements

●We have a limited operating history that you can use to evaluate us, and the likelihood of our success must be considered in light of the problems, expenses, difficulties, complications and delays frequently encountered by a small developing company.
●We must raise additional capital to fund our operations in order to continue as a going concern.
●We have incurred significant losses since our inception and have limited cash available for our operations.
●We have never generated any revenue from product sales or any other sources since inception and may never be profitable.
●We expect that we will need to raise additional capital, which may not be available on acceptable terms, or at all.
●The terms of our October 2025 private placement may make it difficult for us to procure additional financing.

Risks Related to the Discovery and Development of Product Candidates

●Pre - clinical and clinical studies of our product candidates may not be successful. If we are unable to generate successful results from pre - clinical and clinical studies of our product candidates, or experience significant delays in doing so, our business may be materially harmed.
●We may not be successful in our efforts to identify or develop potential product candidates.
●If clinical trials of our product candidates fail to demonstrate safety and efficacy to the satisfaction of regulatory authorities or do not otherwise produce positive results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.
●Any of our product candidates may cause undesirable side effects or have other properties impacting safety that could delay or prevent their regulatory approval or limit the scope of any approved label or market acceptance.
●Even if we complete the necessary pre - clinical studies and clinical trials, we cannot predict whether or when we will obtain regulatory approval to commercialize a product candidate and we cannot, therefore, predict the timing of any revenue from a future product.
●Even if we obtain regulatory approval for a product candidate, we will still face extensive regulatory requirements, and our products may face future development and regulatory challenges.
●We may not be able to maintain orphan drug designation or obtain orphan drug exclusivity for our product candidates.
●Our Rare Pediatric Disease designation from the FDA does not guarantee that the NDA for the product will qualify for a priority review voucher upon approval, and it does not lead to a faster development or regulatory review process or increase the likelihood that any of our product candidates will receive marketing approval.
●We may use our financial and human resources to pursue a particular research program or product candidate and fail to capitalize on programs or product candidates that may be more profitable or for which there is a greater likelihood of success.
●We expect competition in the marketplace for our product candidates, should any of them receive regulatory approval.
●We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to compete effectively.
●The commercial success of our product candidates will depend upon the acceptance of these product candidates by the medical community, including physicians, patients and healthcare payors.
●If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our product candidates, we may be unable to generate any revenues.
●If we obtain approval to commercialize any approved products outside of the United States, Europe and Japan, a variety of risks associated with international operations could materially adversely affect our business.
●Coverage and adequate reimbursement may not be available for our product candidates, if approved, which could make it difficult for us to sell products profitably.

Risks Related to Our Reliance on Third Parties

●We rely on third parties to conduct some aspects of our compound formulation, research and pre - clinical studies, and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such formulation, research or testing.
●We rely, or will rely, on third-party manufacturers to produce the supply of our pre - clinical product, clinical product candidates and commercial supplies of any approved product candidates.
●We rely on limited sources of supply for the drug substance of product candidates and any disruption in the chain of supply may cause a delay in developing and commercializing these product candidates.
●Manufacturing issues may arise that could increase product and regulatory approval costs or delay commercialization.
●We rely on third parties to conduct, supervise and monitor our clinical trials, and if those third parties perform in an unsatisfactory manner, it may harm our business.

Risks Related to Our Intellectual Property

●If we are unable to obtain or protect intellectual property rights related to our future products and product candidates, we may not be able to compete effectively in our markets.
●Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts.
●If we fail to obtain licenses or comply with our obligations in these agreements under which we license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our business.
●We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time consuming and unsuccessful.
●We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties.

Other Risks Related to Our Business Operations and Industry

●The pausing or termination of government grants by the United States government could have a major effect on the pharmaceutical industry, and as a result, our operations and prospects.
●Inadequate funding, government shutdowns, workforce reductions or other policy changes affecting the FDA, the SEC or other government agencies could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.
●Our future success depends on our ability to attract and retain key executives and to attract, retain and motivate qualified personnel.
●We may need to expand our organization and may experience difficulties in managing our growth, which could disrupt our operations.
●Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading.
●Future relationships with customers and third - party payors as well as certain of our business operations may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and health information privacy and security laws. If we are unable to comply, or have not fully complied, with such laws, we could face criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.
●Our operations may be impacted from changes to current regulations and future legislation.
●We face potential product liability, and, if successful claims are brought against us, we may incur substantial liability and costs.
●Cyber security risks and the failure to maintain the confidentiality, integrity, and availability of our computer hardware, software, and Internet applications and related tools and functions could result in damage to our reputation and/or subject us to costs, fines or lawsuits.
●We have been, and may in the future be, adversely affected by health epidemics and pandemics which may significantly harm our business, prospects, financial condition and operating results.
●Business interruptions could delay us in the process of developing our future products.

Risks Related to Being an Israeli Company

●Shareholders may have difficulties enforcing a U.S. judgment, including judgments based upon the civil liability provisions of the U.S. federal securities laws, against us or our executive officers and directors, or asserting U.S. securities laws claims in Israel.
●The rights and responsibilities of our shareholders are governed by Israeli law, which may differ in some respects from the rights and responsibilities of shareholders of U.S. corporations.
●Provisions of Israeli law may delay, prevent or otherwise impede a merger with, or an acquisition of, our company, which could prevent a change of control, even when the terms of such a transaction are favorable to us and our shareholders.

Risks Related to Ownership of Our ADSs and Ordinary Shares

●We do not know whether a market for our securities will be sustained and as a result it may be difficult for shareholders to sell our securities.
●We incur costs and demands upon management as a result of complying with the laws and regulations affecting public companies, which may harm our business
●Failure to achieve and maintain effective internal controls in accordance with Section 404 of the Sarbanes-Oxley Act could have a material adverse effect on our business, results of operation or financial condition. In addition, current and potential shareholders could lose confidence in our financial reporting, which could have a material adverse effect on the price of the ADSs.
●Our failure to meet the continued listing requirements of the Nasdaq Capital Market could result in a delisting of our ADSs.
●The market price for our ADSs may be volatile.
●We may be at risk of securities class action litigation.
●Substantial future sales or perceived potential sales of our ADSs in the public market could cause the price of our ADSs decline.
●Our shareholders may experience substantial dilution as a result of future issuances of our equity securities.
●We have not paid, and do not intend to pay, dividends on our ordinary shares and, therefore, unless our traded securities appreciate in value, our investors may not benefit from holding our securities.
●If we pay dividends or other distributions, an ADS holder may not receive the same distributions or dividends as those we make to the holders of our ordinary shares, and, in some limited circumstances, an ADS holder may not receive dividends or other distributions on our ordinary shares and an ADS holder may not receive any value for them, if it is illegal or impractical to make them available to such ADS holder.
●Holders of ADSs must act through the depositary to exercise their rights.
●Holders of ADSs may be subject to limitations on the transfer of their ADSs.
