Next steps with izicopan
In November 2025, InflaRx announced positive topline data from a Phase 2a basket study exploring izicopan in HS and chronic spontaneous urticaria (CSU). InflaRx believes results from this study provide strong rationale for further development, with a priority placed on HS. In HS, InflaRx has made substantial progress towards Phase 2b readiness and expects to close out communications with the FDA in the upcoming months. In CSU, where InflaRx continues to weigh options, the Company remains in ongoing dialog with key opinion leaders who remain supportive of izicopan's potential in CSU to address unmet need.

Complete Phase 2a results are targeted for release at major scientific meetings this year. In addition, InflaRx expects to host a virtual Capital Markets Day this spring to provide clarity on izicopan's expected clinical development path in HS, greater insight into the HS market opportunity, and updated thinking on izicopan's clinical utility in select additional I&I indications, including AAV.

As the Company evaluates the optimal strategy to fully realize izicopan's potential as a pipeline‐in‐a‐product, it is actively reviewing and considering additional development in AAV. Izicopan was designed as a best‐in‐class therapy, offering differentiated chemistry, metabolic properties, and safety advantages over the currently marketed C5aR inhibitor. This includes minimal CYP3A4/5 inhibition measured in pre-clinical studies, which suggests a low potential for drug-drug interactions and liver toxicity. The Company believes these features could unlock significant opportunities for development across multiple meaningful I&I markets, including AAV, where safer and more active drugs are needed.

Furthermore, with the goal of generating proof-of-concept data in additional I&I indications as efficiently as possible, InflaRx intends to conduct a PK bridging study with izicopan in China this year to expedite subsequent proof-of-concept studies in China and elsewhere.

Summary of izicopan Phase 2a data in HS and CSU reported to date
In HS, izicopan induced rapid, meaningful and consistent reductions in the number of abscesses and nodules (ANs) and draining tunnels (dTs), in addition to improvements in measures such as HiSCR, IHS4, NRS30, and DLQI. Improvements in reported efficacy measures were largely rapid and consistent, beginning from Week 1, and deepened over the 4-week treatment period. Furthermore, initial data reported from 25 HS patients who completed the 4-week off-drug follow-up period showed that HiSCR responses continued to deepen four weeks after the treatment period. No signals of safety concern were detected. Given this positive biologic-like emerging clinical profile, InflaRx believes izicopan's market opportunity in HS could substantially exceed $1 billion.

In CSU, reported improvements in clinical measures such as UAS7 indicate a level of activity that exceeds average historically reported placebo levels and is within the range of existing approved CSU therapies. Furthermore, in the subset of patients with severe CSU at baseline (UAS7 of 28–42) and those who presented with angioedema, the improvement appeared greater. Initial data reported from patients who completed the 4-week off-drug observational follow-up period indicated that patients continued to benefit from izicopan four weeks after the last dose. No signals of safety concern were detected. Overall, InflaRx believes these data suggest that izicopan is active in CSU. Given this positive emerging clinical profile and an addressable market for izicopan that InflaRx believes could exceed $1 billion, the Company is considering further development for izicopan in CSU.

Vilobelimab for pyoderma gangrenosum (PG)
In December 2025, InflaRx announced that post-hoc analyses performed on the Phase 3 trial for vilobelimab in PG previously terminated for futility suggest a positive trend in favor of vilobelimab. The analyses found signals indicating a consistent treatment effect on clinical measures such as disease remission, proportion of patients with >50% reduction of target ulcer volume, DLQI, and ulcer volume mean change from baseline. While InflaRx is currently prioritizing its HS-related interactions with the dermatology division of the FDA, the Company continues to anticipate meeting with the agency to determine a potential development path forward for vilobelimab in PG. InflaRx expects that any future development activities in PG would likely be conducted only in collaboration with a partner.

In addition, late-breaking abstract titled“Vilobelimab Treatment for Ulcerative Pyoderma Gangrenosum: Results from a Multicenter, Randomized, Placebo Controlled Phase 3 Trial” has been selected for an oral presentation during the Late-Breaking Research abstract session at the 2026 American Academy of Dermatology (AAD) Annual Meeting on March 28, 2026, 2:24-2:36 PM MT.

Dr. Thomas Taapken, Chief Financial Officer of InflaRx, said:“Our goal is to implement a clear, focused strategy that directs our resources toward izicopan, our highest value asset and pipeline-in-a-product. With this focus and related significant cost reductions, we have a projected cash runway to mid-2027 and believe we are well positioned to execute on our key milestones and the next phase of our clinical development plan.”

2025 Financial Highlights

GOHIBIC revenue and cost of sales
As part of its strategy focused on capital-efficient execution announced in January 2026, InflaRx carried out significant reductions in GOHIBIC (vilobelimab) commercial spending and related functions, including personnel-related costs, as well as the termination or modification of certain third-party contracts. InflaRx will keep GOHIBIC (vilobelimab) available for ordering inside the United States under its Emergency Use Authorization and maintain the ability to satisfy demand in the United States on a reactive basis.

Cost of sales expenses increased by €4.0 million for the year ended December 31, 2025 compared to the corresponding costs for the year ended December 31, 2024 primarily due to higher inventory write-downs of €4.0 million. As a result of the scaling back and discontinuation of GOHIBIC sales activities in the United States, the related inventory has been fully written down.

Marketing and sales expenses
Marketing and sales expenses for the twelve months ended December 31, 2025 decreased by €2.3 million compared to the twelve months ended December 31, 2024. This decrease was primarily due to lower costs in external services for distribution and marketing expenses.

Research and development expenses
Research and development expenses decreased by €9.6 million for the year ended December 31, 2025, compared to the year ended December 31, 2024, primarily due to lower third-party costs from manufacturing development activities and from clinical trials, which decreased by €7.2 million, and €2.2 million lower other expenses compared to the previous year.

General and administrative expenses
General and administrative expenses increased by €0.5 million to €13.5 million for the year ended December 31, 2025, from €13.0 million for the year ended December 31, 2024. This increase is comprised of higher legal and consulting fees by €0.6 million and higher personnel expenses by €0.3 million, offset by €0.5 million lower other expenses, associated with insurance expenses.

Other income
Other income decreased by €2.6 million for the year ended December 31, 2025, compared to the year ended December 31, 2024, due primarily to lower income from government grants and research allowances. In 2024, upon qualifying for an allowance under the German Research Allowance Act, InflaRx recognized €5.1 million in income relating to expenses eligible for reimbursement, which were incurred in the years 2020 to 2024. In 2025, we recognized €2.6 million for the year 2025. We remain eligible for reimbursement of eligible expenses to be incurred from 2026 to 2027.

Net financial result
For the twelve months ended December 31, 2025, net financial result decreased by €4.3 million from a gain of €6.9 million in the twelve months ended December 31, 2024. This decrease was mainly attributable to the decrease of the foreign exchange result by €8.5 million due to the weakening of the U.S. dollar. Financial result decreased by €1.4 million due to lower interest income on marketable securities. This effect was partially offset by a gain of €5.7 million from the fair value remeasurement of pre-funded warrants issued in February 2025.

Net loss
For the years ended December 31, 2025, and 2024, the Company incurred net losses of €45.6 million or €0.68 per ordinary share and €46.1 million or €0.78 per ordinary share, respectively.

Liquidity and capital resources
As of December 31, 2025, total funds available amounted to approximately €46.2 million, comprised of €16.0 million in cash and cash equivalents and €30.2 million in marketable securities.

Net cash used in operating activities
Net cash used in operating activities increased to €35.3 million in the year ended December 31, 2025, from €48.6 million in the year ended December 31, 2024.

Net cash from investing activities
Net cash used in investing activities during the year ended December 31, 2025 amounted to €3.2 million due to lower proceeds from sales of marketable securities. During the previous year ending on December 31, 2024, the Company had a net cash outflow of €52.4 million due to more cash outflows from the purchase of marketable securities than inflows from the proceeds from sales of marketable securities.

Net cash from financing activities
Net cash generated from financing activities increased to €33.3 million in the year ended December 31, 2025, from €0.4 million in the year ended December 31, 2024, primarily due to higher proceeds from the issuance of shares and pre-funded warrants.

About GOHIBIC (vilobelimab)
In the United States, vilobelimab has been granted an Emergency Use Authorization by the U.S. Food and Drug Administration (FDA) for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving invasive mechanical ventilation (IMV) or extracorporeal membrane oxygenation (ECMO) under the trade name GOHIBIC. The emergency use of GOHIBIC (vilobelimab) is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated, or authorization revoked sooner. GOHIBIC (vilobelimab) is an investigational drug that has not been approved by the FDA for any indication, including for the treatment of COVID-19. There is limited information known about the safety and effectiveness of using GOHIBIC (vilobelimab) to treat people in the hospital with COVID-19. Please see additional information in the Fact Sheet for Healthcare Providers, Fact Sheet for Patients and Parents/Caregivers and FDA Letter of Authorization on the GOHIBIC website .

In the European Union, GOHIBIC (vilobelimab) has been granted marketing authorization (Marketing Authorization) under exceptional circumstances for the treatment of adult patients with SARS-CoV-2-induced acute respiratory distress syndrome (ARDS) who are receiving systemic corticosteroids as part of standard of care and receiving IMV with or without ECMO. The EU approval of GOHIBIC (vilobelimab) is supported by the previously announced results of the multicenter Phase 3 PANAMO trial, one of the largest 1:1 randomized, double-blind, placebo-controlled trials in invasively mechanically ventilated COVID-19 patients in intensive care units. The results showed that vilobelimab treatment improved survival with a relative reduction in 28-day all-cause mortality of 23.9% compared to placebo in the global data set. The data were published in The Lancet Respiratory Medicine.

A Marketing Authorization under exceptional circumstances is recommended when the benefit/risk assessment is determined to be positive but, due to the rarity of the disease, it's unlikely that comprehensive data can be obtained under normal conditions of use. Under the terms of GOHIBIC (vilobelimab)'s approval in the European Commission, InflaRx will provide annual updates to European Medicines Agency on the previously announced clinical platform study by the Biomedical Advanced Research and Development Authority. Vilobelimab is included in this study as one of three new potential therapies for treating ARDS.

The COVID-19 related work described herein was partly funded by the German Federal Government through grant number 16LW0113 (VILO-COVID). All responsibility for the content of this work lies with InflaRx.

About vilobelimab
Vilobelimab is a first-in-class monoclonal anti-human complement factor C5a antibody, which highly and effectively blocks the biological activity of free C5a and demonstrates high selectivity towards its target in human blood. Thus, vilobelimab leaves the formation of the membrane attack complex (C5b-9) intact as an important defense mechanism of the innate immune system, which is not the case for molecules blocking C5. In pre-clinical studies, vilobelimab has been shown to control the inflammatory response-driven tissue and organ damage by specifically blocking free C5a as a key“amplifier” of this response.

About izicopan
Izicopan is an orally administered, small molecule inhibitor of the C5a receptor Ca5R1 that has shown anti-inflammatory therapeutic effects in several pre-clinical disease models and in human studies. Further, in contrast to the marketed C5aR inhibitor, in vitro experiments demonstrated that izicopan has minimal inhibition of the cytochrome P450 3A4/5 (CYP3A4/5) enzymes, which play an important role in the metabolism of a variety of metabolites and drugs, including glucocorticoids. Reported results from a first-in-human study demonstrated that izicopan was well tolerated in treated subjects and exhibited no safety signals of concern in single doses ranging from 3 mg to 240 mg or multiple doses ranging from 30 mg once per day to 90 mg twice per day for 14 days. Pharmacokinetic / pharmacodynamic data support the best-in-class potential of izicopan, with a ≥90% blockade of C5a-induced neutrophil activation achieved over the 14-day dosing period. Topline Phase 2a data further support the safety profile of izicopan, with no reported safety signals of concern. In patients with hidradenitis suppurativa, over 4 weeks of therapy, izicopan provided rapid and clinically meaningful reductions in abscesses and nodules (ANs) and draining tunnels (dTs), robust HiSCR responses that continued to deepen four weeks after the treatment period, and substantial reductions in patient-reported pain scores, overall demonstrating the potential for biologic-like efficacy. In chronic spontaneous urticaria, InflaRx observed substantial reductions in the 7-day Urticaria Activity Score (UAS7) broadly across patients and particularly in those with severe disease, as well as improved disease control as measured by the Urticaria Control Test (UCT7).
