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.

FcRn Basics 5

For some autoimmune diseases, IgG autoantibodies cause disease pathology directly or via immune complexes IgG autoantibodies can be directly pathogenic IgG autoantibodies may also lead to pathogenic immune complexes Characteristics • In ‘classic’ auto-antibody mediated diseases, auto- antibodies tend to be highly specific to extracellular antigens • Most patients have these pathogenic auto-abs, and detection is an integral part of diagnosis • In more complex autoimmune diseases, auto- antibodies are directed towards intracellular or circulating antigens • Auto-antibodies form immune complexes with their antigen (e.g. dsDNA) and may activate innate and adaptive immune system responses, driving aberrant inflammation and end-organ damage Example Diseases • Myasthenia gravis (MG) • Thyroid eye disease (TED) • Warm autoimmune hemolytic anemia (WAIHA) • Immune thrombocytopenic purpura (ITP) • Rheumatoid arthritis (RA) • Primary Sjogren’s Syndrome (pSS) • Inflammatory myositis • Certain forms of vasculitis E.g., in TED, antibodies against thyroid stimulating hormone receptor (TSHR) activate orbital fibroblasts, causing proliferation and swelling around the eye Hypothesis: in treating these diseases, greater IgG reduction may lead to less autoantibody-driven pathogenesis and therefore greater clinical efficacy 6For Investor Audiences Only

The neonatal Fc receptor (FcRn) promotes recycling of IgG antibodies 7 FcRn Mechanism of Action 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 FcRn maintains levels of IgG in circulation by preventing IgG degradation • FcRn extends the half-life of IgG autoantibodies in circulation exacerbating their autoimmune effects • FcRn expressed in a variety of cells Blood Endocytic vesicle Endosome LysosomeMonocyte or endothelial cell Key: Serum proteinIgG FcRn 1 2 3 4 For Investor Audiences Only

Blood Endocytic vesicle Endosome LysosomeMonocyte or endothelial cell Key: Serum proteinIgG FcRn 1 2 3 4 FcRn inhibition promotes IgG degradation 8 Mechanism of Action of FcRn Inhibition 1. 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 FcRn inhibitor blocks binding of pathogenic antibodies to FcRn and promotes their removal and degradation • FcRn inhibition reduces the recycling of IgG antibodies • As a result, IgG is increasingly delivered to lysosomes for degradation • Relative to older, broad-spectrum immunosuppressants, FcRn inhibitors deliver a more targeted approach to immunomodulation FcRn inhibitor For Investor Audiences Only
