**GENERAL INFORMATION**

Unless otherwise indicated or the context otherwise requires, all references in this Quarterly Report on Form 10-Q (the "Quarterly 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 Quarterly 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."

**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

**AND SUMMARY OF RISK FACTORS**

Certain information included in this Quarterly 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;

● our lack of revenue and potential inability to be profitable;

● uncertainties of cash flows and inability to meet working capital needs;

● 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 data exclusivity for our product candidates;

● the potential oversight of programs or product candidates that may be more profitable or more successful;

[**Table of Contents**](#TOC)

● 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 requirements of being a publicly traded company may strain our resources;

● 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 described in Part I – Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2024 ("Form 10-K"), as well as our subsequent reports filed with the SEC.

You are urged to carefully review and consider the various disclosures made throughout this Quarterly 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 Quarterly 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.

#### NOTE 1 – ORGANIZATION AND BUSINESS
Quoin Pharmaceuticals Ltd. ("Quoin Ltd.," or the "Company"), formerly known as Cellect Biotechnology Ltd. ("Cellect"), is the holding company for Quoin Pharmaceuticals, Inc., a Delaware corporation ("Quoin Inc."). Quoin Inc. was incorporated in Delaware on March 5, 2018. Quoin Inc. is the holding company for Quoin Therapeutics Ireland Limited ("Quoin Ireland"), an Irish private company limited by shares. Quoin Ireland was incorporated in Ireland on November 26, 2024. On October 28, 2021, Cellect completed the business combination with Quoin Inc., with Quoin Inc. surviving as a wholly-owned subsidiary of Cellect (the "Merger"). Immediately after completion of the Merger, Cellect changed its name to "Quoin Pharmaceuticals Ltd."

Effective April 9, 2025, the ratio of American Depositary Shares ("ADSs") evidencing 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 and warrant information presented in these unaudited condensed consolidated financial statements and accompanying footnotes has been retroactively adjusted to reflect the Ratio Change and the Reverse Split.

The Company is a late-stage clinical specialty pharmaceutical company focused on the development and commercialization of therapeutic products that treat rare and orphan diseases for which there are currently very limited or no approved treatments or cures. The Company's lead product, QRX003, is under clinical development as a potential treatment for Netherton Syndrome ("NS"), a rare hereditary genetic disease. QRX003 is in two pivotal registrational clinical studies under an open Investigational New Drug ("IND") application with the Food and Drug Administration ("FDA"). The Company has opened six clinical sites in the United States ("US"). The Company has expanded its trials internationally with clinical sites being opened in the Middle East, the United Kingdom and additional countries in Europe, including Spain and Germany. QRX003 is currently being tested in two pediatric NS patients at the Children's Hospital in Dublin, Ireland and the Company is expanding this study to include two additional children with NS in Austria. QRX003 is also being developed as a potential treatment for Peeling Skin Syndrome with the first subject being treated in New Zealand. The company is planning to expand this study to include up to three additional pediatric subjects. In addition, the Company has entered into a Research Agreements with the Queensland University of Technology ("QUT"), under which the Company has obtained an option for a global license to QRX008 for the potential treatment of scleroderma, as well as a Research Agreement with University College Cork ("UCC") for the development of novel topical formulations of rapamycin (sirolimus) as potential treatments for a number of rare and orphan diseases, including microcystic lymphatic malformations, venous malformations and angiofibroma's. Quoin has also entered into 9 commercial partnerships for QRX003 spanning 61 countries outside of its core commercial territories of the US, Western Europe and Japan. These partnership countries include Canada, Australia/New Zealand, the Middle East, China, Taiwan, Hong Kong, Singapore, Israel, Central and Eastern Europe, Turkey as well as several countries in Latin America. To date, no products have been commercialized and no revenue has been generated by the Company.

#### NOTE 2 - LIQUIDITY RISKS AND OTHER UNCERTAINTIES
The unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States ("U.S. GAAP") assuming the Company will continue as a going concern. At September 30, 2025, the Company had cash and cash equivalents balances totaling $1.8 million and investments of $3.6 million. In addition, on October 10, 2025, the Company entered into a Securities Purchase Agreement with several institutional and accredited investors for the issuance and sale in a private placement of securities for gross proceeds of approximately $16.6 million. On October 14, 2025 a further $3.3 million was received by the Company further to the exercise of certain warrants issued by the Company in December 2024.

The Company has incurred net losses every year since inception and has an accumulated deficit of approximately $66.6 million at September 30, 2025. The Company has a limited operating history and has historically funded its operations through debt and equity financings. The Company incurred net losses of approximately $11.5 million, and negative cash flows from operations of $8.5 million for the nine months ended September 30, 2025.

Based upon the Company's current business plans and cash, cash equivalents and investments on hand as at the date of issuance of these financial statements, management has concluded that the Company has sufficient cash and liquidity to continue as a going concern for a period of at least one year from the issuance of the unaudited consolidated financial statements included in this report.

[**Table of Contents**](#TOC)

Additional financing will be required to fund the Company's operating requirements until it achieves commercial profitability, if ever. Such financing may not be available at acceptable terms, if at all. If the Company is unable to obtain additional funding when it becomes necessary, the development of its product candidates will be impacted and the Company would likely be forced to delay, reduce, or terminate some or all of its development programs.

**Other risks and uncertainties:**

The Company is subject to risks common to development stage biopharmaceutical companies including, but not limited to, new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations, product liability, pre-clinical and clinical trial outcome risks, regulatory approval risks, uncertainty of market acceptance and additional financing requirements.

The Company's products require approval or clearance from the FDA prior to commencing commercial sales in the United States. There can be no assurance that the Company's products will receive all of the required approvals or clearances. Approvals or clearances are also required in foreign jurisdictions in which the Company may license or sell its products.

There can be no assurance that the Company's products, if approved, will be accepted in the marketplace, nor can there be any assurance that any future products can be developed or manufactured at an acceptable cost and with appropriate performance characteristics, or that such products will be successfully marketed.

The Company is also dependent on several third party suppliers, in some cases a single source supplier including the contract research organization managing both of the Company's current clinical studies, the supplier of the active pharmaceutical ingredient (API), as well as the contract manufacturer of the drug product for clinical development.

*Nasdaq Listing*

On April 29, 2024, the Company received a letter from the Listing Qualifications staff of The Nasdaq Stock Market, LLC ("Nasdaq") notifying the Company that the closing bid price per ADS was below the required minimum of $1.00 for a period of 30 consecutive business days and that the Company did not meet the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) (the "Minimum Bid Price Requirement"). Pursuant to Nasdaq Rule 5810(c)(3)(A), the Company had an initial period of one hundred eighty (180) calendar days, or until October 28, 2024, which was subsequently extended for an additional one hundred eighty (180) calendar days, or until April 28, 2025. To regain compliance with the Minimum Bid Price Requirement, on April 9, 2025, the Company effected the Ratio Change and Reverse Split (see Note 1). On April 29, 2025, the Company received a letter from Nasdaq stating that the Company's closing bid price per ADS was at $1.00 or greater for the last 13 consecutive business days. Accordingly, the Company regained compliance with Listing Rule 5550(a)(2) and the matter was closed.

There can be no assurance that the Company will be able to maintain compliance with Nasdaq's Minimum Bid Price Requirement for continued listing or other listing requirements. If the Company's ADSs were delisted from Nasdaq, it would have a material negative impact on the actual and potential liquidity of the Company's securities, as well as a material negative impact on the Company's ability to raise future capital.

#### NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

#### Basis of Presentation:
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, such statements include all adjustments (consisting only of normal recurring items) which are considered necessary for a fair presentation of the unaudited condensed consolidated financial statements of the Company as of September 30, 2025 and for the three and nine months then ended. The results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the operating results for the year or any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and related disclosures as of December 31, 2024 and for the year then ended which are included in the Company's Annual Report on Form 10- K, filed with the SEC on March 13, 2025.

[**Table of Contents**](#TOC)

**Principles of Consolidation:**

The accompanying consolidated financial statements include the accounts of Quoin Pharmaceuticals Ltd. and its wholly owned subsidiary. All intercompany transactions and balances are eliminated in consolidation. The functional currency of Quoin Ireland, a wholly-owned subsidiary of the Company, is remeasured into U.S. dollars using the exchange rate in effect at the consolidated balance sheet date. The Company translates the assets and liabilities of its Ireland subsidiary into the United States dollar at the exchange rate in effect on the balance sheet date and those unrealized gains and losses are reported in other comprehensive income or loss. Expenses are remeasured using the average exchange rate in effect during the period. Gains and losses arising from remeasurement of the wholly owned subsidiary's financial statements are included in the determination of net income or loss.

**Reclassification:**

Certain balances in the unaudited condensed consolidated statement of operations for the three and nine month period September 30, 2024, have been reclassified to conform to the presentation in the consolidated statement of operations for the year ended December 31, 2024, specifically the reclassification of travel expenses allocated between general and administrative expenses and research and development expenses. Such reclassifications did not have a material impact on the unaudited condensed consolidated financial statements.

#### Use of Estimates:
**The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could materially differ from those estimates. Management considers many factors in developing the estimates and assumptions that are used in the preparation of these financial statements including: expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that falls within that range of reasonable estimates. Estimates are used in the following areas, among others: settlement of debt or other obligations, stock-based compensation, research and development expense recognition, intangible asset estimated useful lives and impairment assessments, allowances of deferred tax assets, and cash flow assumptions regarding going concern considerations.**

#### Cash and cash equivalents:
The Company considers all highly liquid investments and short-term debt instruments with original maturities of three months or less to be cash equivalents. The Company, from time to time during the periods presented, has had bank account balances in excess of federally insured limits where substantially all cash is held in the United States. The Company has not experienced losses in such accounts. The Company believes that it is not subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

**Investments:**

**Investments as of September 30, 2025 and December 31, 2024 consist of U.S. Treasury Bills and Notes, which are classified as trading securities, totaling $3.6 million and $10.4 million, respectively. The Company determines the appropriate balance sheet classification of its investments at the time of purchase and evaluates the classification at each balance sheet date. All of the Company's U.S. Treasury Bills and Notes held on September 30, 2025 have maturities within six months from the balance sheet date. As of September 30, 2025, the carrying value of the Company's U.S. Treasury Bills and Notes approximates their fair value due to their short-term maturities.**

#### Long-lived assets:
Long-lived assets are comprised of acquired technology and licensed rights to use technology, which are considered platform technology with alternative future uses beyond the current products in development. Such intangible assets are being amortized on a straight-line basis over their expected useful life of 10 years.

[**Table of Contents**](#TOC)

The Company assesses the impairment for long-lived assets whenever events or circumstances indicate the carrying value may not be recoverable. Factors the Company considers that could trigger an impairment review include the following:

● Significant changes in the manner of the Company's use of the acquired assets or the strategy for its overall business,

● Significant underperformance relative to expected historical or projected development milestones,

● Significant negative regulatory or economic trends, and

● Significant technological changes which could render the platform technology obsolete.

The Company recognizes impairment when the sum of the expected undiscounted future cash flows is less than the carrying amount of the asset. Impairment losses, if any, are measured as the excess of the carrying amount of the asset over its estimated fair value. During the three and nine months ended September 30, 2025 and 2024, there were no impairment indicators which required an impairment loss measurement.

#### Operating Segment:
**The Company operates in one business segment, which includes the business of research and development activities related to the development of therapeutic products that treat rare and orphan diseases for which there are currently very limited or no approved treatments or cures. The determination of a single business segment is consistent with the consolidated financial information regularly provided to the Company's chief operating decision maker ("CODM"). The Company's CODM is its Chief Executive Officer, who reviews and evaluates consolidated net loss for purposes of assessing performance, making operating decisions, allocating resources, and planning and forecasting for future periods.**

**In addition to the significant expense categories included within consolidated net loss presented on the Company's unaudited condensed consolidated statements of operations, see below for disaggregated amounts that comprise research and development expenses:**

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Three months ended September 30,**  | **Three months ended September 30,**  | **Nine months ended September 30,**  | **Nine months ended September 30,**  |
|  | **2025** | **2024** | **2025** | **2024** |
| External clinical development expenses | $1645882 | $687666 | $4980796 | $1450903 |
| Personnel related and stock-based compensation | 464008 | 253739 | 1151498 | 726358 |
| Other research and development expenses | 171284 | 138215 | 573604 | 375160 |
| &nbsp;&nbsp;Total research and development expenses | $2281174 | $1079620 | $6705898 | $2552421 |

---

#### Research and development:
Research and development costs are expensed as incurred. Research and development expenses include personnel costs associated with research and development activities, including third-party contractors to perform research, conduct clinical trials and manufacture drug supplies and materials. The Company accrues for costs incurred by external service providers, including contract research organizations and clinical investigators, based on its estimates of service performed and costs incurred. These estimates include the level of services performed by third parties, patient enrollment in clinical trials when applicable, administrative costs incurred by third parties, and other indicators of the services completed. Based on the timing of amounts invoiced by service providers, the Company may also record payments made to those providers as prepaid expenses that will be recognized as expenses in future periods as the related services are rendered.

#### Stock based compensation:
The Company recognizes compensation costs resulting from the issuance of stock-based awards to employees, non-employees and directors as an expense in the consolidated statements of operations over the requisite service period based on a measurement of fair value for each stock-based award. The fair value of each option grant is estimated as of the date of grant using the Black-Scholes option-pricing model. The Company accounts for forfeitures as they occur. The fair value is amortized as compensation cost on a straight-line basis over the requisite service period of the awards, which is generally the vesting period.

[**Table of Contents**](#TOC)

Since the Company has a limited history of trading as a public company, the Company's expected stock volatility is based on a weighting of its historical volatility along with a group of a publicly traded set of peer companies. The Company utilizes the simplified method to estimate the expected term. The risk-free interest rate was determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield was assumed to be zero as the Company has not paid dividends since its inception and does not anticipate paying dividends in the foreseeable future.

#### Fair value of financial instruments:
The Company considers its cash and cash equivalents, investments, accounts payable, accrued expenses to meet the definition of financial instruments. The carrying amounts of these financial instruments approximated their fair values due to the short maturities.

The Company measures fair value as required by ASC Topic 820, *Fair Value Measurements and Disclosures* ("ASC Topic 820"). ASC Topic 820 defines fair value, establishes a framework and gives guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. ASC Topic 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.

#### Earnings (loss) per share:
The Company reports loss per share in accordance with ASC 260-10, *Earnings Per Share*, which provides for calculation of "basic" and "diluted" earnings per share. Basic earnings per share includes no dilution and is computed by dividing net income or loss available to common shareholders by the weighted average common shares outstanding for the period. Diluted earnings per share reflect the potential dilution of securities that could share in the earnings of an entity. The calculation of diluted net earnings (loss) per share gives effect to ordinary shares equivalents; however, other than unexercised prefunded warrants as described below, potential common shares are excluded if their effect is anti-dilutive.

For the three and nine months ended September 30, 2025 and 2024, the number of shares excluded from the diluted net earnings (loss) per share included outstanding warrants to purchase 1,108,159 ADSs and outstanding stock options to purchase 200,627 ADSs, and outstanding warrants to purchase 256,809 ADSs and outstanding stock options to purchase 7,943 ADSs, respectively, as their inclusion in the denominator would be anti-dilutive.

#### NOTE 4 – ACCRUED INTEREST AND FINANCING EXPENSE
On October 2, 2020, Quoin Inc. issued promissory notes (the "2020 Notes") to certain investors ("2020 Noteholders"). The 2020 Notes were mandatorily convertible into 12 ADSs, subject to adjustment and were converted in 2021. The ADSs issued to the 2020 Noteholders did not include accrued interest. Two of the five 2020 Noteholders received their amount due during the year ended December 31, 2022 and the Company's estimate of the liability to the remaining three 2020 Noteholders was estimated to be $1,146,000 as of September 30, 2025 and December 31, 2024. Two of the remaining three 2020 Noteholders are related parties to the Company, the aggregate estimated liability to these parties was $339,000 as of September 30, 2025 and December 31, 2024.

There was no interest expense recognized in both the three and nine month periods ended September 30, 2025 and 2024.

#### NOTE 5 - FAIR VALUE OF FINANCIAL INSTRUMENTS
The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities the Company considers the principal or most advantageous market in which it would transact and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability, such as risks inherent in valuation techniques, transfer restrictions and credit risk. For certain instruments, including cash and cash equivalents, accounts payable, and accrued expenses, it was estimated that the carrying amount approximated fair value because of the short maturities of these instruments.

[**Table of Contents**](#TOC)

Fair value is estimated using various valuation models, which utilize certain inputs and assumptions that market participants would use in pricing the asset or liability. The inputs and assumptions used in valuation models are classified in the fair value hierarchy as follows:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Quoted market prices for similar instruments in an active market; quoted prices for identical or similar assets and liabilities in markets that are not active; and model-derived valuations inputs of which are observable and can be corroborated by market data.

Level 3: Unobservable inputs and assumptions that are supported by little or no market activity and that are significant to the fair value of the asset and liability. The fair value hierarchy gives the lowest priority to Level 3 inputs.

In determining the appropriate hierarchy levels, the Company analyzes the assets and liabilities that are subject to fair value disclosure. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to their fair value measurement.

The following table presents the Company's assets and liabilities that are measured at fair value on a recurring basis by fair value hierarchy at September 30, 2025 and December 31, 2024:

---

#### NOTE 9 – IN-LICENSED TECHNOLOGY

#### Skinvisible:
In October 2019, Quoin Inc. entered into the Exclusive Licensing Agreement (as amended from time to time, the "License Agreement") with Skinvisible Pharmaceuticals, Inc. ("Skinvisible"), under which Skinvisible granted the Company an exclusive royalty-bearing license relating to the production and manufacture of prescription drug products related to certain patents held by Skinvisible, including those related to QRX003 and QRX004. The Company made Skinvisible a one-time non-refundable, non-creditable license fee of $1 million (the "License Fee"). In addition, the Company agreed to pay Skinvisible a single digit royalty percentage of the Company's net sales revenues for any licensed product covered by the patent rights licensed under the License Agreement. The Company also agreed to pay Skinvisible 25% of any revenues the Company receives as royalties in the event that the Company sublicenses any licensed products to a third party. The License Agreement also requires that the Company make a one-time $5 million payment to Skinvisible upon receiving approval in the U.S. or European Union, whichever occurs first, for the first drug product developed using intellectual property licensed thereunder. There were no milestone or royalty obligations due at September 30, 2025 and December 31, 2024.

#### NOTE 10 - INTANGIBLE ASSETS
Intangible assets are as follows:

#### NOTE 12 – RESEARCH, CONSULTING AGREEMENTS AND COMMITMENTS

#### Research agreements
In November 2020, Quoin Inc. entered into a Master Service Agreement with Therapeutics Inc. for the management of the preclinical and clinical development of QRX003 for Netherton Syndrome. The initial term of the agreement was three years with automatic one year extensions, and the agreement required the execution of individual work orders. Quoin Inc. may terminate any work order for any reason with 90 days written notice subject to costs incurred through termination and a defined termination fee, unless there is a material breach by Therapeutics Inc. A work order was entered into in June 2022 for the first QRX003 clinical study at an expected estimated cost of approximately $4.4 million. An additional work order was entered into in December 2022 for a second QRX003 clinical study at an expected estimated cost of approximately $830,000. An amended and restated change order for the two studies was entered into in December 2024 at an estimated total remaining cost from August 2024 of approximately $3.6 million for the two studies combined. For the three and nine months ended September 30, 2025 and 2024, the Company incurred research and development expense under these agreements of approximately $522,000 and $1,281,000 and $275,000 and $926,000 respectively.

In November 2021, the Company entered into a research agreement with Queensland University of Technology (QUT) for a pre-clinical research program for the development of a product to treat Netherton Syndrome of approximately $250,000. In May 2022, the Company entered into a second research agreement with QUT for the development of a product to treat Scleroderma of approximately $610,000. Each agreement remains in place until the completion of the research program, which in each case was initially anticipated to be 18 months from execution. For the three and nine months ended September 30, 2025 and 2024, the Company did not incur any costs related to these agreements. In July 2025 the Company announced that, in light of the expected near - term completion of the QRX003 clinical program for Netherton Syndrome, the Company has discontinued Netherton Syndrome research program with QUT. The Company is planning to schedule a meeting with QUT to discuss the future direction of the Scleroderma research program.

In June 2024, the Company signed a research agreement with The School of Pharmacy at University College Cork, Ireland (UCC). The scope of the agreement encompasses the development of novel topical formulations of rapamycin (sirolimus) as potential treatments for a number of rare and orphan diseases for which there are currently no approved therapies or cures. Under the terms of the agreement, based on the achievement of certain milestones, the Company will fund up to approximately €567,000 ($665,000) plus VAT over an anticipated 2-1/2 year period to support the UCC research program to investigate the development of a number of topical rapamycin formulations for future development as potential treatments for several rare and orphan diseases. Following completion of the research program, the Company will have the option to advance the clinical development of rapamycin formulations developed by UCC. Work on this research project commenced in December 2024. For the three and nine months ended September 30, 2025, the Company incurred a research and development expense under these agreements of approximately $48,000 and $168,000 respectively.

**Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations**

*You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes thereto included in Part I-Item 1 of this Form 10-Q. This discussion and other parts of this report contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions that are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Our actual results could differ materially from those discussed in these forward-looking statements. See "Cautionary Note Regarding Forward-Looking Statements" in this Form 10-Q.* 

**Overview**

We are a late-stage clinical specialty pharmaceutical company focused on the development and commercialization of therapeutic products that treat rare and orphan diseases for which there are currently either no approved or very limited treatments or cures. Our lead product, QRX003, is in clinical development as a potential treatment for Netherton Syndrome, a rare hereditary genetic disease. QRX003 is in two pivotal registrational clinical studies under an open IND application with the FDA. We have opened six clinical sites in the US . We have expanded our trials internationally in the Middle East, the United Kingdom and additional countries in Europe, including Spain and Germany. QRX003 is currently being tested in two pediatric NS patients at the Children's Hospital in Dublin, Ireland and we are expanding this study to include additional children with NS in Austria and potentially in Spain, the United Kingdom and other countries. QRX003 is also being developed as a potential treatment for Peeling Skin Syndrome with the first subject being treated in New Zealand. We are planning to expand this study to include up to three additional pediatric subjects. In addition, we entered into a Research Agreement with the Queensland University of Technology, under which we have obtained an option for a global license to QRX008 for the potential treatment of scleroderma, as well as a Research Agreement with University College Cork for the development of novel topical formulations of Rapamycin (sirolimus) as potential treatments for a number of rare and orphan diseases for which there are either limited or no approved therapies or cures, including microcystic lymphatic malformations, venous malformations and angiofibroma's. We have also entered into 9 commercial partnerships for QRX003 spanning 61 countries outside of its core commercial territories of the US, Western Europe and Japan. These partnership countries include Canada, Australia, New Zealand, the Middle East, China, Taiwan, Hong Kong Singapore, Israel, Central and Eastern Europe, Turkey as well as several countries in Latin America.

Our mission is to develop and commercialize proprietary therapeutic drug products that treat rare and orphan diseases, particularly those where none currently exists. To achieve this, we plan to:

● complete the late-stage clinical testing of QRX003 in NS and, if successful, file for marketing approval in the United States, Europe, Japan and the other territories for which we have commercial agreements in place;

● prepare to commercialize QRX003 by establishing our own sales infrastructure in the U.S. Europe, Japan and entering into distribution partnerships in other territories such as those currently established for Canada, Australia/New Zealand, the Middle East, China, Hong Kong, Taiwan, Latin America, Central and Eastern Europe, Turkey and Singapore; and

● pursue business development activities by seeking partnering, licensing, merger and acquisition opportunities or other transactions to further expand our pipeline and drug-development capabilities.

To date, no products have been commercialized and no revenue has been generated. We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. Accordingly, we will need to raise additional capital prior to the commercialization of QRX003 or any other product candidate. Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our operating activities through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and our ability to continue our operations. See "Liquidity and Capital Resources".

**Recent Developments**

***Increase in Authorized Capital***

On August 21, 2025, at our 2025 Annual General Meeting of Shareholders (the "Annual Meeting"), our shareholders approved an amendment to our Amended and Restated Articles of Association, as amended to increase our authorized Ordinary Share capital from 100,000,000 Ordinary Shares to 5,000,000,000 Ordinary Shares.

***Adoption of New Equity Plan***

At the Annual Meeting, our shareholders approved the Quoin Pharmaceuticals Ltd. 2025 Equity Incentive Plan (the "2025 Plan") and authorized the issuance pursuant to the 2025 Plan of up to 3,000,000 Ordinary Shares, subject to an automatic annual increase equal to the smaller of (a) fifteen percent (15%) of the number of Ordinary Shares issued and outstanding on a fully diluted basis on the immediately preceding December 31, or (b) an amount determined by our Board of Directors.

***Private Placement Offering***

On October 10, 2025, we entered into a securities purchase agreement with several institutional and accredited investors relating to the issuance and sale in a private placement transaction (the "Private Placement") of (i) ordinary shares represented by 15,152 American Depositary Shares ("ADSs") and (ii) pre-funded warrants to purchase ordinary shares represented by 1,993,939 ADSs, together with (A) Series H Warrants to purchase ordinary shares represented by up to 2,009,091 ADSs, (B) Series I Warrants to purchase ordinary shares represented by up to 2,009,091 ADSs, (C) Series J Warrants to purchase ordinary shares represented by up to 2,009,091 ADSs, and (D) Series K Warrants to purchase ordinary shares represented by up to 2,009,091 ADSs. The Series H Warrants, Series I Warrants, Series J Warrants and Series K Warrants are collectively referred to herein as the "Ordinary Warrants." The combined purchase price was $8.25 per each ADS and accompanying Ordinary Warrants and $8.2499 per each pre-funded warrant and accompanying Ordinary Warrants, which pricing was designed to be in accordance with the "Minimum Price" requirement as defined in the Nasdaq rules. The private placement closed on October 14, 2025 (the "Closing Date"). We received upfront net proceeds of approximately $15 million from the Private Placement, after deducting estimated offering expenses payable by us, including placement agent fees and expenses. We intend to use the upfront net proceeds from the Private Placement for general corporate purposes, which may include operating expenses, research and development, including completion of clinical development of QRX003 for Netherton Syndrome, working capital, future acquisitions and general capital expenditures. We may also receive up to an aggregate of $88 million of additional gross proceeds if the Ordinary Warrants are exercised in full for cash.

Dennis Langer, one of our directors, participated in the Private Placement. Mr. Langer purchased ordinary shares represented by 15,152 ADSs and accompanying Ordinary Warrants for a total purchase price of approximately $128,641, at a combined purchase price of $8.49. In accordance with Nasdaq Rules, Mr. Langer's purchase price was based upon the consolidated closing bid price from the trading day immediately preceding the date we entered into the securities purchase agreement, plus $0.50.

***Regulatory Update***

On October 21, 2025, we announced that the FDA has granted Orphan Drug Designation to QRX003, for the treatment of Netherton Syndrome. The designation follows previously granted Orphan Drug Designation by the European Medicines Agency (the "EMA") in May 2025. The FDA's Orphan Drug Designation program provides orphan status to therapies intended for the treatment, diagnosis, or prevention of rare diseases that affect fewer than 200,000 people in the United States. This designation provides certain benefits, including tax credits for qualified clinical testing, waiver or partial payment of FDA application fees and seven years of market exclusivity, if approved.

**Components of Our Results of Operations**

***Operating Expenses***

Our current operating expenses consist of two components - research and development expenses, and general and administrative expenses.

***Research and Development Expenses***

Research and development costs are expensed as incurred. Research and development expenses include personnel costs associated with research and development activities, including third-party contractors to perform research, conduct clinical trials and manufacture drug supplies and materials. We utilize outside consultants and third parties to conduct the majority of our research and development, under the supervision of our management team.

[**Table of Contents**](#TOC)

Future research and development expenses may include:

● employee-related expenses, such as salaries, bonuses and benefits, consultant-related expenses, share-based compensation, overhead related expenses and travel related expenses for our research and development personnel;

● expenses incurred under agreements with CROs, as well as consultants that support the implementation of the clinical studies described above;

● manufacturing and packaging costs in connection with conducting clinical trials and for stability and other studies required to support the NDA filing as well as manufacturing drug product for commercial launch;

● formulation, research and development expenses related to QRX003; and other product candidates we may choose to develop; and

● costs for sponsored research.

Research and development activities will continue to be central to our business plan. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect our research and development expenses to be significant over the next several years as personnel and compensation costs increase and we conduct late-stage clinical studies and prepare to seek regulatory approval for QRX003 and any other future product candidate.

The duration, costs and timing of clinical trials of QRX003 and any other future product candidate will depend on a variety of factors that include, but are not limited to:

● the number of trials required for approval;

● the per patient trial costs;

● the number of patients that participate in the trials;

● the number of sites included in the trials;

● the countries in which the trial is conducted;

● the length of time required to enroll eligible patients;

● the number of doses that patients receive;

● the drop-out or discontinuation rates of patients;

● the potential additional safety monitoring or other studies requested by regulatory agencies;

● the duration of patient follow-up;

● the timing and receipt of regulatory approvals; and

● the efficacy and safety profile of our product candidates.

[**Table of Contents**](#TOC)

***General and Administrative Expenses***

General and administrative expenses consist primarily of compensation and employee related expenses including non-cash stock-based compensation, professional fees and other corporate expenses. We anticipate that our general and administrative expenses will increase in the future to support our continued research and development activities. These increases will likely include compensation and employee-related expenses including stock-based compensation, increased costs related to the potential hiring of personnel, travel costs and fees to outside consultants, lawyers and accountants.

***Other Expenses (income)***

Other expenses (income) consist primarily of interest income and unrealized loss (gain) on investments.

**Liquidity and Capital Resources**

We have incurred net losses every year since inception and had an accumulated deficit of approximately $66.6 million at September 30, 2025. We have a limited operating history and have historically funded our operations through debt and equity financings. We incurred net losses of approximately $11.5 million and negative cash flows from operations of $8.5 million for the nine months ended September 30, 2025. At September 30, 2025, we had cash and cash equivalent balances totaling $1.8 million and investments of $3.6 million. In addition, on October 10, 2025, the Company entered into a Securities Purchase Agreement with several institutional and accredited investors for the issuance and sale in a private placement of securities for gross proceeds of approximately $16.6 million. On October 14, 2025 a further $3.3 million was received by the Company further to the exercise of certain warrants issued by the Company in December 2024. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of planned clinical trials and our expenditures on other research and development activities. After taking into account the net proceeds we received in connection with the Private Placement that closed on October 14, 2025, we have determined that we have sufficient resources to effect our business plan for at least one year from the issuance of the unaudited consolidated financial statements included in this report. We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for one or more of our product candidates, which is subject to uncertainty. Additional financing may be required to fund our other operating requirements until we reach commercial profitability, if ever, which may not be available at acceptable terms, if at all.

**Future Funding Requirements**

We will need to obtain further funding through public or private offerings of our capital stock, debt financing, collaboration and licensing arrangements or other sources, the requirements for which will depend on many factors, including:

● the scope, timing, rate of progress and costs of our drug development efforts, preclinical development activities, the timing of laboratory testing and clinical trials for our product candidates;

● the number and scope of clinical programs we decide to pursue;

● the cost, timing and outcome of preparing for and undergoing regulatory review of our product candidates;

● the scope and costs of development and commercial manufacturing activities;

● the cost and timing associated with commercializing our product candidates, if they receive marketing approval;

● the extent to which we acquire or in-license other product candidates and technologies;

● the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;

● our ability to establish and maintain collaborations on favorable terms, if at all;

● our efforts to enhance operational systems and our ability to attract, hire and retain qualified personnel, including personnel to support the development of our product candidates and, ultimately, the sale of our products, following FDA approval;

● our implementation of operational, financial and management systems; and

● the costs associated with being a public company.

Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of QRX003, any future product candidate, or potentially discontinue operations.

[**Table of Contents**](#TOC)

To the extent that we raise additional capital through the sale of our equity or convertible debt securities, and pursuant to the exercise of the warrants issued to the investors in our prior public offerings, the ownership interest of our equity holders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our equity holders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or proposed products, or to grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our drug development or future commercialization efforts or grant rights to develop and market any future product that we would otherwise prefer to develop and market ourselves.

**Summary Statement of Cash Flows**

As of September 30, 2025, we had approximately $5,413,000 in cash and cash equivalents and investments in marketable securities. The table below presents our cash flows for the nine month periods ended September 30, 2025 and 2024:

***Operating Activities***

Net cash used in operating activities was approximately $8,506,000 and $5,621,000 in the nine months ended September 30, 2025 and 2024, respectively. The increase in 2025 was primarily due to an increase in net loss, offset by an increase in accounts payable and accrued expenses and a decrease in prepaid expenses.

***Investing Activities***

Investment activities provided net cash of $6,991,000 and $1,290,000 in the nine months ended September 30, 2025 and 2024, respectively. The cash provided in investing activities for the nine months ended September 30, 2025 consisted of net sales and redemptions of US Treasury Bills and Notes. The cash provided in investing activities for the nine months ended September 30, 2024 consisted of net purchases of short maturity US Treasury Bills and Notes from the proceeds of the March 2024 public offering.

***Financing Activities***

Net cash (used in) financing activities was approximately $277,000 for the nine months ended September 30, 2025. The net cash used in financing activities was due to repayments of amounts due to officers of $450,000, partially offset by the receipt of approximately $173,000 in net proceeds from the exercise of warrants. Net cash provided by financing activities was approximately $5,046,000 for the nine months ended September 30, 2024. The net cash provided increased due to the receipt of approximately $5.5 million in net proceeds from our March 2024 public offering partially offset by repayments of amounts due to officers of $450,000.

***Research and Development Commitments***

In October 2019, Quoin Inc. entered into the Exclusive Licensing Agreement (as amended from time to time, the "License Agreement") with Skinvisible Pharmaceuticals, Inc. ("Skinvisible"), under which Skinvisible granted us an exclusive royalty-bearing license relating to the production and manufacture of prescription drug products related to certain patents held by Skinvisible, including those related to QRX003 and QRX004. We made Skinvisible a one-time non-refundable, non-creditable license fee of $1 million (the "License Fee"). In addition, we agreed to pay Skinvisible a single digit royalty percentage of our net sales revenues for any licensed product covered by the patent rights licensed under the License Agreement. We also agreed to pay Skinvisible 25% of any revenues we receive as royalties in the event that we sublicense any licensed products to a third party. The License Agreement also requires that we make a $5 million payment to Skinvisible upon receiving approval in the U.S. or European Union, whichever occurs first, for the first drug product developed using intellectual property licensed thereunder.

In November 2020, Quoin Inc. entered into a Master Service Agreement with Therapeutics Inc. for the management of the preclinical and clinical development of QRX003 for Netherton Syndrome. The initial term of the agreement was three years with automatic one year extensions, and the agreement required the execution of individual work orders. Quoin Inc. may terminate any work order for any reason with 90 days written notice subject to costs incurred through termination and a defined termination fee, unless there is a material breach by Therapeutics Inc. A work order was entered into in June 2022 for the first QRX003 clinical study at an expected estimated cost of approximately $4.4 million through 2024. An additional change order was entered into in December 2022 for a second QRX003 clinical study at an expected estimated cost of approximately $830,000. An amended and restated change order for the two studies was entered into in December 2024 at an estimated total remaining cost from August 2024 of approximately $3.6 million for the two studies combined. For the three and nine months ended September 30, 2025 and 2024, we incurred a research and development expense under these agreements of approximately $522,000 and $1,281,000 and $275,000 and $926,000 respectively.

In November 2021, we entered into a research agreement with Queensland University of Technology (QUT) for a pre-clinical research program for the development of a product to treat Netherton Syndrome of approximately $250,000. In May 2022, we entered into a second research agreement with QUT for the development of a product to treat Scleroderma of approximately $610,000. Each agreement remains in place until the completion of the research program, which in each case was initially anticipated to be 18 months from execution. For the three and nine months ended September 30, 2025 and 2024, we did not incur any costs related to these agreements. In July 2025 we announced that, in light of the expected near-term completion of the QRX003 clinical program for Netherton Syndrome, we have discontinued Netherton Syndrome research program with QUT. We are planning to schedule a meeting with QUT to discuss the future direction of the Scleroderma research program.

In June 2024, we entered into a research agreement with The School of Pharmacy at UCC. The scope of the agreement encompasses the development of novel topical formulations of Rapamycin (sirolimus) as potential treatments for a number of rare and orphan diseases for which there are currently very limited or no approved therapies or cures. Under the terms of the agreement, based on the achievement of certain milestones, we will fund up to approximately €567,000 ($665,000) plus VAT over an anticipated 2-1/2 year period to support the UCC research program to investigate the development of a number of topical rapamycin formulations for future development as potential treatments for several rare and orphan diseases. Following completion of the research program, we will have the option to advance the clinical development of rapamycin formulations developed by UCC. Work on this research project commenced in December 2024. For the three and nine months ended September 30, 2025, we incurred a research and development expense under these agreements of approximately $48,000 and $168,000 respectively.

***Critical Accounting Estimates***

There have been no material changes to our critical accounting estimates from the information provided in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," included in our Annual Report on Form 10-K for the year ended December 31, 2024.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk.**

We are a smaller reporting company as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and are not required to provide the information otherwise required under this Item 3.

[**Table of Contents**](#TOC)

**Item 4. Controls and Procedures.**

**Evaluation of Disclosure Controls and Procedures**

We maintain disclosure controls and procedures, which are designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation, as of the end of the period covered by this report, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15e under the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level.

**Changes in Internal Control over Financial Reporting**

During the quarter ended September 30, 2025, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

[**Table of Contents**](#TOC)

**PART II – OTHER INFORMATION**

**Item 1. Legal Proceedings.**

From time to time, we may become involved in legal or administrative proceedings or be subject to claims arising in the ordinary course of our business. We are currently not a party to any material legal or administrative proceedings, and we are not aware of any pending or threatened material legal or administrative proceedings against us.

**Item 1A. Risk Factors.**

Except as set forth below, there have been no material changes in our risk factors from the risks previously reported in Part 1, Item 1A, "Risk Factors" of our Form 10-K. You should carefully consider the factors discussed in Form 10-K, which could materially affect our business, financial condition or future results. The risks described in our Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. We may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC.

***Our failure to meet the continued listing requirements of The Nasdaq Capital Market could result in a delisting of our ADSs.***

Our ADSs are listed on the Nasdaq Capital Market, which imposes, among other requirements, a minimum bid requirement.

On April 29, 2024, we received a letter from the Listing Qualifications staff of The Nasdaq Stock Market, LLC ("Nasdaq") notifying us that the closing bid price per ADS was below the required minimum of $1.00 for a period of 30 consecutive business days and that we did not meet the Minimum Bid Price Requirements set forth in Nasdaq Listing Rule 5550(a)(2). Pursuant to Nasdaq Rule 5810(c)(3)(A), we had an initial period of one hundred eighty (180) calendar days, or until October 29, 2024, which was subsequently extended a further one hundred eighty (180) calendar days, or until April 28, 2025 (the "Compliance Period"), to regain compliance with Nasdaq's Minimum Bid Price Requirement. To regain compliance with the Nasdaq Listing Rules, on April 9, 2025, we effected a change in the ratio of ADSs evidencing Ordinary Shares from one (1) ADS representing one (1) Ordinary Share to one (1) ADS representing thirty-five (35) Ordinary Shares. On April 29, 2025, we received a letter from Nasdaq stating that our closing bid price per ADS was at $1.00 or greater for the last 13 consecutive business days. Accordingly, we regained compliance with Listing Rule 5550(a)(2) and the matter was closed.

Nasdaq Listing Rule 5810(c)(3)(A)(iv) states that any listed company that fails to meet the Minimum Bid Price Requirement and has effected a reverse stock split over the prior one-year period, or has effected one or more reverse stock splits over the prior two-year period with a cumulative ratio of 250 shares or more to one, will not be eligible for an automatic 180-day grace compliance period and the Nasdaq Listing Qualifications Department is obligated to immediately issue a delisting determination. Therefore, if we were to fall out of compliance with the Minimum Bid Price Requirement prior to April 9, 2026, we would not be able to effect a reverse stock split and would immediately be issued a delisting determination. Further, the Nasdaq rule provides that a company will not be considered to have regained compliance with the Minimum Bid Price Requirement if the company takes an action to achieve compliance (such as a reverse split) and that action results in the Company's security falling below the numeric threshold for another listing requirement.

There can be no assurance that we will be able to maintain compliance with Nasdaq's Minimum Bid Price Requirement or other continued listing requirements. As of September 30, 2025, our stockholders' equity was below the minimum requirement of $2,500,000 set forth in Nasdaq Listing Rule 5550(b)(1). Although the Private Placement, which closed on October 14, 2025, likely increased our stockholders' equity, there can be no assurance that we will regain compliance with the stockholder's equity requirement. If we fail to comply with the Nasdaq listing requirements and do not regain compliance, our ADSs will be subject to delisting by Nasdaq. In the event our ADSs are delisted, our ADS price and market liquidity of our ADSs will be adversely affected, which will impact our ability to sell securities in the market. Further, delisting from Nasdaq could also have other negative effects, including potential loss of confidence by partners, suppliers and employees.

There can be no assurance that our ADSs will continue to trade on Nasdaq or trade on the over-the counter markets or any public market in the future. In the event our ADSs are delisted, our ADS price and market liquidity of our ADSs will be adversely affected which will impact your ability to sell your securities in the market.

[**Table of Contents**](#TOC)

If we fail to meet any of Nasdaq's listing standards, our ADS will be subject to delisting. If that were to occur, our ADS would be subject to rules that impose additional sales practice requirements on broker-dealers who sell our securities. The additional burdens imposed upon broker-dealers by these requirements could discourage broker-dealers from effecting transactions in our ADS. This would adversely affect the ability of investors to trade our ADS and would adversely affect the value of our ADS. Delisting from Nasdaq would cause us to pursue eligibility for trading of our ADS on other markets or exchanges, or on an over-the-counter market. In such case, our stockholders' ability to trade or obtain quotations of the market value of our ADS would be severely limited because of lower trading volumes and transaction delays. These factors could contribute to lower prices and larger spreads in the bid and ask prices of these securities. There can be no assurance that our ADS, if delisted from Nasdaq, would be listed on a national securities exchange, a national quotation service or the over-the-counter markets. Delisting from Nasdaq could also result in negative publicity, adversely affect the market liquidity of our ADS, decrease securities analysts' coverage of us or diminish investor, supplier and employee confidence. In addition, our stock could become a "penny stock," which would make trading of our ADS more difficult.

The delisting of our ADS from Nasdaq may make it more difficult for us to raise capital on favorable terms in the future, or at all. Such a delisting would likely have a negative effect on the price of our ADS and would impair your ability to sell or purchase our ADS when you wish to do so. Further, if our ADS were to be delisted from Nasdaq, our ADS would cease to be recognized as a covered security, and we would be subject to additional regulation in each state in which we offer our securities. Moreover, there is no assurance that the actions that we have taken to restore our compliance with the Nasdaq Minimum Bid Price Requirement will stabilize the market price or improve the liquidity of our ADS, prevent our ADS from falling below the Nasdaq minimum bid price required for continued listing again or prevent future non-compliance with other applicable Nasdaq listing requirements.

***We have incurred significant losses since our inception and have limited cash available for our operations.***

To date, we have not commercialized any products and have not generated any revenue. We have incurred net losses every year since inception and we have an accumulated deficit of approximately $66.6 million at September 30, 2025. We have historically funded our operations through debt and equity financings. At September 30, 2025, we had cash and cash equivalent balances totaling $1.8 million and investments of $3.6 million. Following the completion of the Private Placement on October 14, 2025, we believe that we have sufficient cash and liquidity for operating our business for twelve months from the date of filing this Form 10-Q. We are subject to risks common to late-stage clinical specialty pharmaceutical companies including, but not limited to, unanticipated or higher than expected clinical trial costs and the ability to estimate such occurrences, if any, on our cash, liquidity, additional financing requirements, and availability. Accordingly, we may need to raise additional funds during this period. We have devoted a majority of our financial resources to research and development, including our preclinical and ongoing clinical development activities. To date, we have funded our operations primarily through our founders' funding expenditures and the sale of equity and convertible securities.

We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for one or more of our product candidates or these candidates participate in Early Access or Named Patient programs, which we expect will take a number of years and is subject to significant uncertainty. Additional financing will be required to complete the research and development of our product candidates and our other operating requirements, which may not be available at acceptable terms, if at all. If we are unable to obtain additional funding when it becomes necessary, the development of our product candidates will be impacted and we would likely be forced to delay, reduce, or terminate some or all of our development programs, all of which could have a material adverse effect on our business, results of operations and financial condition.

We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. The net losses we incur may fluctuate significantly from quarter to quarter. We anticipate that our expenses will increase substantially if and as we:

● continue and/or initiate clinical development of our product candidates, including—QRX003—a topical lotion comprised of a broad-spectrum serine protease inhibitor, formulated with the proprietary Invisicare® technology, which is under clinical development as a potential treatment for Netherton Syndrome ("NS");

● further enhance our internal control systems;

● initiate the development of additional product candidates for other rare disease indications;

● acquire or in-license other products and technologies and advance those product candidates into clinical trials;

[**Table of Contents**](#TOC)

● seek marketing approvals for our product candidates that successfully complete clinical trials;

● ultimately establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain marketing approval;

● maintain, expand and protect our intellectual property portfolio;

● hire additional clinical, regulatory, research, executive and administrative personnel; and

● create additional infrastructure to support our operations and our product development and planned future commercialization efforts.

Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to predict the timing or amount of increased expenses and when we will be able to achieve or maintain profitability, if ever. In addition, our expenses could increase beyond expectations if we are required by the FDA or other foreign regulatory agencies to perform studies and trials in addition to those that we currently anticipate.

Even if one or more of the product candidates that we independently develop is approved for commercial sale, we may incur significant costs associated with commercializing any approved product. Even if we are able to generate revenues from the sale of any approved products, we may not become profitable and may need to obtain additional funding to continue operations.

***Limits on our ability to sell securities under the Purchase Agreements may affect our ability to finance our operations.***

Pursuant to the terms of the Purchase Agreement that we entered into in connection with the Private Placement that closed on October 14, 2025, we agreed, subject to certain exceptions, (i) to not enter into variable rate financings for a period of 180 days following the Closing Date, (ii) to not enter into any equity financings until the later of 60 days after the effective date of the initial registration statement required to be filed pursuant to the Registration Rights Agreement (or, if earlier, if all applicable securities have been sold, or could be sold without restriction, pursuant to Rule 144 or Section 4(a)(1)) and 90 days after the Closing Date (the "Initial Standstill Period"), and (iii) to not enter into any equity financings at an effective price per ADS or Ordinary Share that is less than $8.25 from the last day of the Initial Standstill Period until 180 days after the effective date of the initial registration statement required to be filed pursuant to the Registration Rights Agreement (or, if earlier, if all applicable securities have been sold, or could be sold without restriction, pursuant to Rule 144 or Section 4(a)(1)). The Purchase Agreement further provides that the Purchasers have a right of participation in certain subsequent financings by us or any of our subsidiaries in an amount equal to up to an aggregate of 25% of such subsequent financings for 12 months following the date of the Purchase Agreement. If we require additional funding while these restrictive covenants remain in effect, we may be unable to effect a financing transaction on terms acceptable to us, or at all, while also remaining in compliance with the terms of the Purchase Agreement, or we may be forced to seek a waiver from the Purchasers, which such Purchasers are not obligated to grant to us.If we are unable to obtain additional funding when it becomes necessary, the development of our product candidates will be impacted, which could have a material adverse effect on our business.

***Inadequate funding for the FDA, the SEC and other government agencies, including from government shutdowns, or other disruptions to these agencies' staffing and operations, 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.***

Currently, federal agencies in the U.S. are operating under a federal government shutdown due to the expiration of the continuing resolution that expired on September 30, 2025. The duration of the current government shutdown is unknown. In addition, the current U.S. administration is focused on reducing costs of the federal government generally, including significantly reducing the number of government employees. Without appropriation of additional funding to federal agencies, our business operations related to our product development activities for the U.S. market could be impacted. The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, the ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

[**Table of Contents**](#TOC)

Disruptions at the FDA and other federal agencies, including substantial leadership departures, personnel cuts, and policy changes, may also slow the time necessary for new drugs to be reviewed and/or approved, which would harm our business. These changes have been reported by some within the pharmaceutical industry as creating instances of delays in the FDA's responsiveness or in its ability to review IND submissions or applications, issue regulations or guidance, or implement or enforce regulatory requirements in a timely fashion or at all.

If the current U.S. federal government shutdown is prolonged or if the FDA, NIH, SEC or the USPTO experiences significant decreases in funding or personnel, it could significantly impact the ability of the FDA to issues licenses needed for conduct of our clinical trials, the NIH to conduct research or provide grants, and the abilities of the FDA and the USPTO to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

**Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.**

There were no unregistered sales of equity securities during the quarter ended September 30, 2025, other than as reported in our Current Reports on Form 8-K filed with the SEC.

**Item 3. Defaults Upon Senior Securities.**

None.

**Item 4. Mine Safety Disclosures.**

Not applicable.

**Item 5. Other Information.**

During the third quarter of 2025, none of our directors or executive officers adopted or terminated any "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement" (as each term is defined in Item 408(a) of Registration S-K).
