&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***1.***  ***Summary of significant accounting policies and other disclosures***

***b)*** ***Basis of preparation***

These interim condensed consolidated financial statements for the nine-month reporting period ended September 30, 2025, and 2024 have been prepared in accordance with IAS 34 Interim Financial Reporting. These condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements. The condensed consolidated financial statements requires management to make judgments, estimates and assumptions which are the same as at year end. Estimates and underlying assumptions are reviewed on an ongoing basis. Accordingly, this report is to be read in conjunction with the financial statements in the Company's annual report for the year ended December 31, 2024 on Form 20–F.

The interim condensed consolidated financial statements were authorized for issue by the board of directors of the Company (the "Board of Directors") on November 10, 2025.

The financial statements are presented in euros (€). The euro is the functional currency of InflaRx N.V. and InflaRx GmbH. The functional currency of InflaRx Pharmaceuticals Inc. is the U.S. dollar.

All financial information presented in euros have been rounded to the nearest euro. Accordingly, numerical figures shown as totals in some tables may not be an arithmetic aggregation of the figures that precede them or may deviate from other tables.

The accounting policies adopted are consistent with those followed in the preparation of the Group's annual consolidated financial statements for the year ended December 31, 2024, except for the adoption of new standards effective as of January 1, 2025, as set out below. The Group has not adopted any other standard, interpretation or amendment that has been issued but is not yet effective early.

The following amendments were adopted effective January 1, 2025, and do not have a material impact on the consolidated financial statements of the Group:

<br> • Amendments to IAS 21 Effects of Changes in Foreign Exchange Rates: Lack of exchangeability

The following standards issued will be adopted in a future period, and the potential impact, if any, they will have on the Group's consolidated financial statements is being assessed:

<br> • Amendments to IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures, Classification and Measurement of Financial Instruments

<br> • Amendments to IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures, Contracts Referencing Nature-dependent Electricity

------

For the three months ended September 30, 2025, net financial result decreased by €0.7 million to a loss of €2.8 million from a loss of €2.1 million for the three months ended September 30, 2024. This decrease is mainlyattributable to the fair value revaluation of pre-funded warrants issued in February 2025 in the amount of €-3.2 million and to the foreign exchange result which increased by €2.8 million.. Financial result decreased by €0.3 million due to lower interest income on marketable securities, in each case, compared to the three months ended September 30, 2024. The decrease is offset by an increase of the foreign exchange result of €2.8 million.

For the nine months ended September 30, 2025, net financial result decreased by €1.9 million to a gain of €0.4 million in the nine months ended September 30, 2025 from a gain of €2.3 million in the nine months ended September 30, 2024. This decrease is mainly attributable to the decrease of the foreign exchange result by €4.5 million. Finance result decreased by € 1.1 million due to lower interest income on marketable securities. This effect is partially compensated by a gain of € 3.8 million from the fair value revaluation of pre-funded warrants, issued in February 2025.

In February 2025, the Company issued 6,750,000 pre-funded warrants to certain investors in the context of a public offering of securities. As of September 30, 2025, the fair value of the warrants amounted to €7.7 million (Level 1).

As of September 30, 2025, the fair value of current and non-current financial assets (primarily quoted debt securities) amounted to €38.5 million (as of December 31, 2024: €42.6 million) (Level 1). The Group's debt instruments at amortized cost consist solely of quoted securities that are graded highly by credit rating agencies such as S&P Global and, therefore, are considered low credit risk investments.

As of September 30, 2025, current and non-current financial assets increased by €0.9 million to €38.4 million compared to €37.6 million of December 31, 2024. The increase is mainly due to the subsequent reinvestment of interest bearing bank deposits (cash and cash equivalents) in marketable securities (financials assets).

As of September 30, 2025, trade and other payables decreased by €2.1 million to €9.4 million compared to €11.5 million as of December 31, 2024. As of December 31, 2024 the Company temporarily had higher trade payables from CRO's.

***15.*** ***Equity***

On June 30, 2023, the Company filed a Form F-3, or the 2023-Registration Statement, with the Securities Exchange Commission, or the SEC, with respect to the offer and sale of securities of the Company, which became effective on July 11, 2023. The aggregate initial offering price of the securities that the Company may offer and sell under this prospectus will not exceed $250.0 million. In June 2024, the Company subsequently filed a prospectus supplement with the SEC relating to an at-the-market program providing for the sale of up to $75.0 million of our ordinary shares over time pursuant a sales agreement with Leerink Partners LLC, or the Sales Agreement.

In the nine months ended September 30, 2025, we issued 145,420 ordinary shares under our ATM program, resulting in $353 thousand in net proceeds. Following this issuance under the ATM program, the remaining value authorized for sale under the ATM program is $73.5 million.

In February 2025, the Company completed an underwritten public offering of 8,250,000 ordinary shares at a public offering price of $2.00 per ordinary share and, in lieu of ordinary shares to certain investors, pre-funded warrants to purchase 6,750,000 ordinary shares. The public offering price for each pre-funded warrant was equal to the price per share at which the ordinary shares were sold to the public, minus $0.001, which is the exercise price of each pre-funded warrant. The warrants are only exercisable by cashless exercise; the amount of ordinary shares to be received upon cashless exercise of such warrants is dependent on the Company's market share price at the time of exercise. The net proceeds from the offering were €26.8 million ($28.0 million). The warrants have an indefinite expiration and are fully or partly exercisable at any time.

------

***b)*** ***Share-based payment expense recognized***

For the three months ended September 30, 2025, the Company has recognized €0.6 million (2024: €0.7 million) of share-based payment expense in the statements of operations and comprehensive loss.

For the nine months ended September 30, 2025, the Company has recognized €4.2 million (2024: €3.7 million) of share-based payment expense in the statements of operations and comprehensive loss including €356 thousand (ended September 30, 2024: nil) for the extension of option for the eight year option terms to ten years.

None of the share-based payment awards were dilutive in determining earnings per share due to the Group's loss position.

***c)*** ***Share options exercised***

During the nine months ended September 30, 2025, no shares (2024: nil) were issued upon the exercise of share options, resulting in no proceeds to the Company (ended September 30, 2024: nil).

***17.*** ***Protective foundation***

According to the articles of association of the Company, up to 169,300,000 ordinary shares and up to 169,300,000 preferred shares with a nominal value of €0.12 per share are authorized to be issued. All shares are registered shares. No share certificates shall be issued.

In order to deter acquisition bids, the Company's general meeting of shareholders approved the right of an independent foundation under Dutch law, or protective foundation, to exercise a call option pursuant to the call option agreement, upon which preferred shares will be issued by the Company to the protective foundation of up to 100% of the Company's issued capital held by others than the protective foundation, minus one share. The protective foundation is expected to enter into a finance arrangement with a bank or, subject to applicable restrictions under Dutch law, the protective foundation may request the Company to provide, or cause the Company's subsidiaries to provide, sufficient funding to the protective foundation to enable it to satisfy its payment obligation under the call option agreement.

These preferred shares will have both a liquidation and dividend preference over the Company's ordinary shares and will accrue cash dividends at a pre-determined rate. The protective foundation would be expected to require the Company to cancel its preferred shares once the perceived threat to the Company and its stakeholders has been removed or sufficiently mitigated or neutralized. The Company believes that the call option does not represent a significant fair value based on a level 3 valuation since the preferred shares are restricted in use and can be cancelled by the Company.

During the three months ended September 30, 2025, the Company expensed €15 thousand (2024: €12.5 thousand) of ongoing costs to reimburse expenses incurred by the protective foundation.

During the nine months ended September 30, 2025, the Company expensed €45 thousand (2024: €38 thousand) of ongoing costs to reimburse expenses incurred by the protective foundation.

#### Overview
InflaRx (Nasdaq: IFRX) is a biopharmaceutical company pioneering anti-inflammatory therapeutics by applying its proprietary anti-C5a and anti-C5a receptor technologies to discover, develop and commercialize highly potent and specific inhibitors of the complement activation factor C5a and its receptor. C5a is a powerful inflammatory mediator involved in the progression of a wide variety of inflammatory diseases. InflaRx has developed vilobelimab, a novel, intravenously delivered, first-in-class, anti-C5a monoclonal antibody that selectively binds to free C5a and has demonstrated disease-modifying clinical activity and tolerability in multiple clinical studies. InflaRx is also developing INF904, an orally administered small molecule inhibitor of C5a-induced signaling via the C5a receptor.

#### Vilobelimab for the treatment of PG
In May 2025, we announced that the Independent Data Monitoring Committee (IDMC) conducting the unblinded interim analysis for the Phase 3 trial for vilobelimab in pyoderma gangrenosum (PG), recommended that the trial be stopped due to futility. This recommendation was based on data analysis of the first 30 patients enrolled in the study, with no unexpected adverse events noted by the IDMC. We are in the process of winding down the clinical study and expect to be able to analyze and to comment on the study results by the end of this fiscal year.

#### Vilobelimab for the treatment of severe COVID-19
In April 2023, we received an EUA, from FDA for GOHIBIC (vilobelimab) for the treatment of COVID-19 in critically ill, invasively mechanically ventilated hospitalized adult patients. The EUA is supported by the previously announced results of the multicenter Phase 3 PANAMO trial, which demonstrated a relative reduction in 28-day all-cause mortality by 23.9%. Subsequently, in June 2023, we began the commercialization of GOHIBIC (vilobelimab) in the United States under the EUA. In January 2025, the EC granted marketing authorization under exceptional circumstances for GOHIBIC (vilobelimab) for the treatment of adult patients with SARS-CoV-2-induced ARDS who are receiving systemic corticosteroids as part of standard of care and receiving invasive mechanical ventilation with or without extracorporeal membrane oxygenation.

------

#### GOHIBIC (vilobelimab) for ARDS
In June 2025, BARDA announced enrollment of the first patient in the JUST BREATHE Phase 2 platform clinical trial investigating novel therapeutic candidates for ARDS. The clinical trial is being implemented by the PPD clinical research business of Thermo Fisher Scientific and aims to evaluate the safety and efficacy of three host-directed therapeutic candidates at up to 60 U.S. sites, targeting a total enrollment of 600 hospitalized adult patients with ARDS.

#### Anti-C5aR inhibitor INF904
To expand the breadth of our anti-C5a/C5aR technologies, we are also developing INF904, a product candidate that targets the C5a receptor. In INF904, we discovered a small molecule C5aR inhibitor that in pre-clinical studies has shown potential for superior characteristics to the only approved C5aR inhibitor, avacopan. INF904 has provided higher plasma exposure in animals, including non-human primates, and improved inhibitory activity in a hamster neutropenia model compared to avacopan. Furthermore, in contrast to avacopan, in vitro experiments showed INF904 has substantially less inhibition of the cytochrome P450 enzymes 3A4/5 (CYP3A4/5). INF904 demonstrated potential for anti-inflammatory therapeutic effects in several preclinical disease models. In January 2024, we announced the positive results of a single and multiple ascending dose study with INF904 in healthy volunteers. In December 2024, we announced that the first patient was dosed in the Phase 2a basket study in chronic spontaneous urticaria, or "CSU", and hidradenitis suppurative, or "HS", with data expected by early Nobember. In May 2025, we announced the successful completion of the required sub-chronic and chronic toxicology studies for INF904. No safety signals of concern were identified, supporting the potential for long-term dosing in future clinical efforts. Additional required non-clinical studies remain ongoing as planned. INF904 is a promising product candidate for being developed in several disease areas of inflammation, where orally available therapeutics are not available or a medical need exists despite availability of other therapies.

#### INF904 for the treatment of CSU
We have been pursuing development of INF904 for the treatment of CSU in a Phase 2a trial. CSU is a debilitating and unpredictable skin disease characterized by intensely itchy hives / wheals and angioedema. The burden of this chronic disease is high and impacts sleep, mental health, quality of life and productivity due to absences from school and work. CSU is estimated to affect around 40 million people worldwide. CSU patients have been reported to show elevated C5a levels, a major activator of mast cells and basophils which are thought to be significant contributors to CSU pathogenesis. In addition, studies suggest that complement activation (including C5a) in CSU can lead to histamine release. Current treatments are limited, and a significant unmet need exists in a sizable proportion of patients. INF904 for the treatment of HS

We have also been pursuing development of INF904 for the treatment of HS in a Phase 2a trial. HS is a chronic, recurrent, debilitating neutrophil-driven inflammatory disease that can persist for years and tremendously impacts quality of life; it is characterized by abscesses, nodules and draining tunnels which can flare and cause scarring. INF904 inhibits the known C5a-induced effects on neutrophil activation and tissue accumulation of immune cells, including generation of tissue damaging mechanisms (enzyme release and oxidative radical formation) as well as induction of NETosis – mechanisms thought to be involved in HS progression and draining tunnel formation. Clinical evidence with existing C5a/C5aR products also supports that blocking this pathway reduces lesion counts. Patients' responses to treatment with approved anti-TNF-alpha or anti-IL17 drugs are known to wane over time in a significant number of cases; and treatment with new therapeutics acting through other molecular mechanisms are needed for these patients.

#### Anti-C5a antibody IFX002
We are developing IFX002 for the treatment of chronic inflammatory diseases. IFX002 is a highly potent anti- C5a antibody, which binds to the same domain of the C5a protein as vilobelimab, but which has a higher humanization grade and altered pharmacokinetic properties compared to vilobelimab. IFX002 is currently in preclinical development. We consider IFX002 to be a life-cycle management product to vilobelimab, given the long remaining patent life of IFX002.

------

#### Financial highlights
As of September 30, 2025, we had available funds amounting to €44.4 million, composed of €6.4 million in cash and cash equivalents and €37.9 million in marketable securities. Of the €6.4 million cash and cash equivalents, €1.1 million are held in euros and €5.3 million are held in U.S. dollars. Marketable securities held in U.S. dollars have a nominal value of $38.0 million (€32.0 million), marketable securities held in EUR have a nominal value of €6.0 million. We believe that our current funds on hand will be sufficient to fund our planned operations into 2027.

We anticipate that our expenses might increase if and as we:

<br> • continue research, preclinical and clinical development efforts, as applicable, for any existing and future product candidates, including vilobelimab, INF904 and IFX002;

<br> • actively seek to identify additional research programs and additional product candidates;

<br> • seek regulatory and marketing approvals for our product candidates that successfully complete clinical trials, if any;

<br> • establish and expand sales, marketing, distribution and other commercial infrastructure now and in the future to commercialize various products for which we may obtain marketing authorization or approval, if any;

<br> • require the scale-up and validation of the manufacturing process and the manufacturing of larger quantities of product candidates for clinical development and, potentially, commercialization;

<br> • collaborate with strategic partners to optimize the manufacturing process for vilobelimab, IFX002, INF904 and other pipeline products;

<br> • maintain, expand and protect our intellectual property portfolio;

<br> • hire and retain additional personnel, such as commercial, marketing, clinical, quality control and scientific personnel; and

<br> • add operational, financial and management information systems and personnel, including personnel to support our product development as well as commercialization and help us comply with our obligations as a public company.

Our ability to become and remain profitable depends on our ability to generate revenue. We do not expect to generate significant revenue unless and until we are, or any future collaborator is, able to obtain full marketing authorization or approval for, and successfully commercialize, one or more of our product candidates. Successful commercialization will require achievement of key milestones, including completing clinical trials of vilobelimab, INF904 and any other product candidates, obtaining marketing authorization or approval for these product candidates, manufacturing, marketing and selling those products for which we, or any of our future collaborators, may obtain marketing authorization or approval, satisfying any post-marketing requirements and obtaining reimbursement for our products from private insurance or government payors. Because of the uncertainties and risks associated with these activities, we are unable to accurately predict the timing and amount of revenues, and if or when we might achieve profitability. We and any future collaborators may never succeed in these activities and, even if we do, or any future collaborators do, we may never generate revenue that is large enough for us to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis.

We expect our financial condition and operating results to continue to fluctuate from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. In order to succeed, we will need to transition from a company with a research and development focus to a company capable of undertaking commercial activities. We may encounter unforeseen expenses, difficulties, complications and delays, and may not be successful in such a transition.

------

Accordingly, we may seek to further fund our operations through public or private equity or debt financings or other sources, including strategic collaborations. We may, however, 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 develop vilobelimab or any additional product candidates.

Our failure to become and remain profitable could depress the market price of our ordinary shares and could impair our ability to raise capital, pay dividends, expand our business, diversify our product offerings or continue our operations. If we continue to suffer losses as we have in the past, investors may not receive any return on their investment and may lose their entire investment.

#### Sales and marketing expenses
<br> • Sales and marketing expenses have consisted principally of:

<br> • external services for distribution of GOHIBIC (vilobelimab) to build and maintain the necessary commercial and logistical infrastructure, including external sales professionals;

<br> • marketing activities;

<br> • employee-related expenses, including salaries, benefits and stock-based compensation expense based upon employees' role within the organization; and

<br> • professional services fees in conjunction with making GOHIBIC (vilobelimab) available to hospitals and patients in the U.S.

#### Research and development expenses
Research and development expenses have consisted principally of:

<br> • expenses incurred under agreements with CROs, contract manufacturing organizations, or CDMOs, consultants and independent contractors that conduct research and development, preclinical and clinical activities on our behalf;

<br> • employee-related expenses, including salaries, benefits and stock-based compensation expense based upon employees' role within the organization; and

<br> • professional fees for lawyers related to the protection and maintenance of our intellectual property.

We expense research and development costs as incurred. We recognize costs for certain development activities, such as preclinical studies and clinical trials, based on an evaluation of the progress to completion of specific tasks. We use information provided to us by our vendors such as status of patient enrollment or clinical site activations for measuring services received and efforts expended. Research and development activities are central to our business model.

Our research and development expenses primarily relate to the following key programs:

• **Vilobelimab.** Our expenses associated with vilobelimab have decreased in 2025 will continue to decrease compared to 2024, given the recent decision to stop our Phase 3 study in PG. However, we will still incur some costs associated to our clinical activities, including the wind down of the Phase 3 trial in PG.

• **INF904.** We are developing INF904, a product candidate that targets C5aR. We expect to incur additional costs by advancing the clinical and non-clinical development of INF904. Specifically, we expect to incur expenses through the ongoing Phase 2 clinica trial. We plan to continue studying INF904 in complement-mediated, chronic autoimmune and inflammatory conditions where an oral low molecular weight compound might have advantages or is needed for patients and where oral delivery is the medically preferred route of administration. Initially targeted indications include CSU and HS.

• **IFX002**. We are developing IFX002 for the treatment of chronic inflammatory indications. IFX002 is a highly potent anti-complement C5a antibody with a higher humanization grade and altered PK properties compared to vilobelimab and is currently in pre-clinical development. Expenses for this program mainly consist of salaries, costs for preclinical testing conducted by CROs and costs to produce preclinical material.

------

• **Other development programs.** Our other research and development expenses relate to our preclinical studies of other product candidates and discovery activities, expenses for which mainly consist of salaries, costs for production of preclinical compounds and costs paid to CROs.

#### General and administrative expenses
Our general and administrative expenses consist principally of:

<br> • employee-related expenses, including salaries, benefits and stock-based compensation expense based upon employees' role within the organization;

<br> • professional fees for auditors and consulting expenses not related to research and development activities;

<br> • professional fees for lawyers not related to the filing, prosecution, protection and maintenance of our intellectual property;

<br> • insurance expenses including directors and officers liability insurance premiums; and

<br> • cost of facilities, travel, communication and office expenses.

For the three months ended September 30, 2025, net financial result decreased by €0.7 million to a loss of €2.8 million from a loss of €2.1 million for the three months ended September 30, 2024. This decrease is mainly attributable to the fair value remeasurement of pre-funded warrants issued in February 2025 in the amount of €3.2 million and to the foreign exchange result which increased by €2.8 million. Financial result decreased by €0.3 million due to lower interest income on marketable securities, in each case, compared to the three months ended September 30, 2024. This effect is compensated by the increase of the foreign exchange result of €2.8 million.

---

Our cost of sales during the nine months ended September 30, 2025 amounted to €2.4 million primarily due to higher inventory write-downs of €2.4 million. Write-downs were mainly due to quantities of unfinished goods on-hand exceeding quantities expected to be sold prior to expiry and were determined by a multiple scenario analysis. In the same period in 2024 write downs were lower due to a longer shelf-life of inventory as of September 30, 2024.

---

For the nine months ended September 30, 2025, net financial result decreased by €1.9 million to a gain of €0.4 million in the nine months ended September 30, 2025 from a gain of €2.3 million in the nine months ended September 30, 2024. This decrease is mainly attributable to the decrease of the foreign exchange result by €4.5 million. Financial result decreased by €1.1 million due to lower interest income on marketable securities. This effect is partially compensated by a gain of €3.8 million from the fair value remeasurement of pre-funded warrants, issued in February 2025.

#### Liquidity and capital resources
Since inception, we have incurred significant operating losses. For the nine months ended September 30, 2025, we incurred a net loss of €35.0 million. To date, we have financed our operations primarily through the sale of our securities. As of September 30, 2025, we had cash and cash equivalents in the amount of €6.4 million and financial assets in the amount of €38.4 million, comprised of marketable securities in the amount of €37.9 million and other financial assets amounting to €0.4 million. Our cash and cash equivalents primarily consist of bank deposit accounts and fixed U.S. dollar term deposits.

|  **Cash and cash equivalents at the end of the period** | **6448117** | **26205938** |

---

&nbsp;&nbsp;&nbsp;&nbsp;*1. Net cash from/used in operating activities*

The use of cash in all periods resulted primarily from our net losses, adjusted for non-cash charges and changes in components of working capital. Net cash used in operating activities decreased to €30.6 million in the nine months ended September 30, 2025, from €36.7 million in the nine months ended September 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;*2. Net cash from/used in investing activities*

Net cash from investing activities decreased by €55.1 million in the nine months ended September 30, 2025, mainly due to lower proceeds from maturity of marketable securities in the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. These proceeds were reinvested into interest bearing bank deposits, which are accounted for as part of cash and cash equivalents.

&nbsp;&nbsp;&nbsp;&nbsp;*3.*&nbsp;&nbsp;&nbsp;&nbsp; *Net cash from/used in financing activities*

Net cash from financing activities increased by €27.1 million in the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024, due to a public offering of ordinary shares and pre-funded warrants in the nine months ended September 30, 2025.

#### Funding requirements
We expect our expenses associated with vilobelimab to decrease in 2025 compared to 2024, given the recent decision to terminate our Phase 3 study in PG. However, we will still incur some costs associated with our clinical activities, including those related to winding down the Phase 3 trial in PG. Furthermore, we will incur expenses, as we continue discussions with the FDA related to the planned submission of a BLA for full approval of GOHIBIC (vilobelimab) to treat severe COVID-19 and potentially additional related indications, continue to pursue commercializing of GOHIBIC (vilobelimab) under the EUA for emergency use as granted by the FDA. Lastly, we also incur expenses related to the manufacturing of clinical trial materials and in connection with further optimizing our manufacturing process for vilobelimab in compliance with regulatory standards. Furthermore, we also have established commercial scale production options and have initiated manufacturing campaigns to be able to serve the market needs in the United States under the granted EUA.

We are advancing the development of INF904 through the ongoing Phase 2 clinical study, and expect to initiate additional clinical studies in the future. In parallel, we are also continuing with non-clinical development activities in relation to the manufacturing and additional non-clinical animal studies in order to prepare for this future development.

If clinical data is supportive, we may seek marketing approval for any product candidates that we successfully develop. Additionally, we will validate and further develop the manufacturing process of our products to be able to apply for marketing authorization and to be able to provide a commercial-grade product. If we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to establishing sales, marketing, distribution, and other commercial infrastructure to commercialize such products. We will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce, or eliminate our research and development programs or future commercialization efforts. We believe that our existing cash and cash equivalents and financial assets will enable us to fund our operating expenses and capital expenditure requirements under our current business plan into 2027.

------

Until such time, if ever, that we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, royalty-based financings, future collaborations, strategic alliances, licensing arrangements and revenues from product sales. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the interest of our current shareholders will be diluted, and the terms of these securities may include voting or other rights that adversely affect your rights as an ordinary shareholder. Debt 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 funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us.

*At-the-market program*

On June 28, 2024, we entered into a Sales Agreement with Leerink Partners LLC, to sell our ordinary shares from time to time through an at-the-market, or ATM, equity offering program of up to $75.0 million.

In the nine months ended September 30, 2025, we issued 145,420 ordinary shares under our ATM program, resulting in $353 thousand in net proceeds. Following this issuance under the ATM program, the remaining value authorized for sale under the ATM program is $73.5 million.
