Important Notice and Disclaimer Information and Sources Certain information contained in this presentation relates to or is based on studies, publications, surveys and other data obtained from third-party sources and InflaRx’s own internal estimates and research. While InflaRx believes these third-party sources to be reliable as of the date of this presentation, it has not independently verified, and makes no representation as to the adequacy, fairness, accuracy or completeness of, any information obtained from third-party sources. In addition, all of the market data included in this presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions. Further, while we believe our own internal research is reliable, such research has not been verified by any independent source. Avacopan Data We have not conducted a head-to-head comparison of Avacopan to INF904 in a clinical trial but have compared the published data for Avacopan to data from our Phase 1 clinical trial of INF904. For the purpose of conducting pre-clinical studies (hamster neutropenia study), we synthesized Avacopan and did a side-by-side comparison. While we believe this comparison to Avacopan to be useful and appropriate, the value of this and other comparisons to Avacopan in this presentation may be limited because they are not derived from a head-to-head trial and they are from trials that were conducted under different protocols at different sites and at different times. Without head-to-head data, we are unable to make comparative claims between INF904 and Avacopan. About InflaRx InflaRx GmbH (Germany) and InflaRx Pharmaceuticals Inc. (USA) are wholly owned subsidiaries of InflaRx N.V. (together, “InflaRx”). InflaRx (Nasdaq: IFRX) is a biotechnology company pioneering anti-inflammatory therapeutics by applying its proprietary anti-C5a and anti-C5aR technologies to discover, develop and commercialize first-in-class, potent and specific inhibitors of the complement activation factor C5a and its receptor C5aR. C5a is a powerful inflammatory mediator involved in the progression of a wide variety of inflammatory diseases. InflaRx’s lead product candidate, vilobelimab, is 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 in different indications.

INF904: Potential Best-in-Class C5aR Inhibitor Plasma Concentration Sampled at 8 hours: INF904 = 538 ng/mL Avacopan-like molecule = 119 ng/mL Page 23 PRE-CLINICAL IN VIVO EFFICACY COMPARISON OF INF904 to AVACOPAN* Inhibition of in vivo neutrophil activation by INF904 compared to Avacopan-like molecule* Source: InflaRx data on file. *Avacopan synthesized based on the published structure and publicly available data. Experiment: Challenge of rodents with C5a leads to neutrophil activation and consequent adherence (sticking) of neutrophils to the endothelial cell wall of vessels = mimicking a neutropenia (vehicle). This effect can be completely inhibited when C5aR activation is blocked. Outcome: INF904 is significantly superior to an identical dose of the Avacopan* in blocking C5aR, leading to an approximate doubling of neutrophil inhibition in vivo in this rodent model. Note: INF904 dosing within this experiment exerts an approx. 4.5-fold higher plasma level 8 h after dosing when compared to the identical dosing with the Avacopan*.
INF904 Phase I Study: PK Results from SAD Part Page 24 In comparison to published data for Avacopan, INF904 is approximately 3-fold higher in Cmax and 10-fold higher in systemic exposure (AUClast) for comparable doses (3, 10, 30 mg) Parameter Unit Dose INF904 Avacopan* AUCinf h.ng/ml 3 mg 285 25 10 mg 1264 130 30 mg 5956 628 AUClast h.ng/ml 3 mg 254 23 10 mg 1117 122 30 mg 5197 557 Cmax ng/ml 3 mg 21.5 9 10 mg 74.8 25 30 mg 289 79 tmax hr 3 mg 3.5 1.2 10 mg 4 1.7 30 mg 5.01 1.7 INF904 240mg INF904 60mg INF904 30mg INF904 120mg Avacopan* 30mg INF904 240mg INF904 60mg INF904 30mg INF904 120mg Source: Bekker et al.

INF904 confirms its best-in-class C5aR inhibitor potential within this Phase I single ascending dose study Summary Topline Results from INF904 Phase I SAD Study Page 27 Key Outcomes INF904 was well tolerated in treated healthy volunteers and resulted in no safety signals of concern in single ascending doses ranging from 3mg to 240mg. INF904 demonstrated a favorable PK profile: Tmax 6 hours, dose proportional exposure from 3 to 240mg. INF904 demonstrated a strong C5a blocking potential at C5a concentrations observed in human diseases. INF904 can be formulated with a higher drug strength of 30mg per capsule vs. 10mg per capsule for the marketed comparator.
