Forward-looking Statements 2 This presentation contains forward-looking statements for the purposes of the safe harbor provisions under The Private Securities Litigation Reform Act of 1995 and other federal securities laws. The use of words such as "can," "may," "might," "will," "would," "should," "expect," "believe," "estimate," "design," "plan," "intend," and other similar expressions are intended to identify forward-looking statements. Such forward looking statements include Immunovant's expectations regarding patient enrollment, timing, design, and results of clinical trials of its product candidates and indication selections; Immunovant's plan to develop batoclimab and IMVT-1402 across a broad range of autoimmune indications; expectations with respect to the safety and monitoring plan and size of the safety database for these planned clinical trials; the timing of discussions with regulatory agencies; the size and growth of the potential markets for Immunovant's product candidates and indication selections; Immunovant's plan to explore in subsequent study periods follow-on treatment with alternative dosing regimens; Immunovant's expectations regarding its cash runway; Immunovant's beliefs regarding the potential benefits of batoclimab's and IMVT-1402's unique product attributes; and Immunovant's expectations regarding the issuance and term of any pending patents. All forward-looking statements are based on estimates and assumptions by Immunovant's management that, although Immunovant believes to be reasonable, are inherently uncertain. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that Immunovant expected. Such risks and uncertainties include, among others: initial results or other preliminary analyses or results of early clinical trials may not be predictive of final trial results or of the results of later clinical trials; results of animal studies may not be predictive of results in humans; the timing and availability of data from clinical trials; the timing of discussions with regulatory agencies, as well as regulatory submissions and potential approvals; the continued development of Immunovant's product candidates, including the timing of the commencement of additional clinical trials and resumption of current trials; Immunovant's scientific approach, clinical trial design, indication selection, and general development progress; future clinical trials may not confirm any safety, potency, or other product characteristics described or assumed in this presentation; any product candidate that Immunovant develops may not progress through clinical development or receive required regulatory approvals within expected timelines or at all; Immunovant's pending composition of matter patent for IMVT-1402 may not be issued; Immunovant's product candidates may not be beneficial to patients, or even if approved by regulatory authorities, successfully commercialized; the potential impact of the ongoing COVID-19 pandemic, geopolitical tensions, and adverse macroeconomic conditions on Immunovant's clinical development plans and timelines; Immunovant's business is heavily dependent on the successful development, regulatory approval and commercialization of batoclimab and IMVT-1402; Immunovant is at an early stage in development for IMVT-1402 and in various stages of clinical development for batoclimab; and Immunovant will require additional capital to fund its operations and advance batoclimab and IMVT-1402 through clinical development. These and other risks and uncertainties are more fully described in Immunovant's periodic and other reports filed with the Securities and Exchange Commission (SEC), including in the section titled "Risk Factors" in Immunovant's most recent Annual Report on Form 10-K, its Form 10-Q filed with the SEC on November 4, 2022, and Immunovant's subsequent filings with the SEC. Any forward-looking statement speaks only as of the date on which it was made. Immunovant undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise.

IgG and FcRn inhibitor are taken up into cells in endocytic vesicles 2. FcRn inhibitor binds to FcRn in endosomes 3. IgGs are blocked from forming complexes with FcRn 4. Non-receptor bound IgGs are degraded in lysosomes 1. IgG is taken up into cells in endocytic vesicle 2. FcRn-IgG complexes are sorted from unbound proteins 3. Unbound proteins are trafficked to lysosome for degradation 4. IgG is recycled back into circulation

Encouraging Pharmacodynamic Signals Observed from Phase 2b Trial of Batoclimab in Thyroid Eye Disease Source: Batoclimab Phase 2b TED trial data on file at Immunovant, Inc. 1SRR is the "Sample to Reference Ratio". This cell-based assay readout is the ratio of the sample signal to that of a reference control, expressed as %. A value less than 140 is considered negative for stimulatory antibody; a value greater than or equal, positive for stimulatory antibody. The efficacy of batoclimab and clinical outcomes were deemed inconclusive, in part, because the study was terminated early. Stimulatory anti-TSHR antibodies concentration 29

Key Learnings from Historical and Ongoing CIDP Trials Applied to Address Challenges Unique to CIDP 35 Trial risks Mitigations Mitigation included in other anti-FcRn Trials\* Mitigation included in IMVT trial Disease heterogeneity and challenging diagnosis Diagnostic algorithm X Mix of active and inactive disease among those enrolled creates risk of low relapse rate in the placebo arm, thereby shrinking potential effect size for the investigational product Patients enrolled in placebo arm of trial may not have demonstrated initial response to investigational product Double enrichment: Not All\*\*1.Subjects must worsen after withdrawal / taper of standard of care (e.g. IVIG/SCIG, PLEX, or steroids) on study entry, AND 2.Subjects must then improve on open label investigational product Not All\*\* Steroids are a common standard of care outside the US and often can't be fully tapered, weakening double enrichment Third enrichment: Primary endpoint on IVIG/SCIG/Plex cohort only to maximize the potential effect size X Lack of dose exploration Data on multiple doses in "Period 1" of trial will inform future development strategy X Single large trial limits flexibility to optimize product label and differentiation Smaller, initial pivotal trial that can be adjusted or complemented with a second smaller pivotal trial to optimize product label and differentiation based on new data X Notes: \*Other anti-FcRn trials in CIDP include efgartigimod, nipocalimab, and rozanolixizumab. \*\*clinical trial designs for efgartigimod in CIDP and nipocalimab in CIDP include double enrichment in trial design. Rozanolixizumab ph2 trial in CIDP did not include double enrichment. Two-stage approach, to accommodate additional registration trial, if necessary, has the potential to deliver a differentiated product label with a larger effect size
