•Immunovant’s new management team is focused on rapid clinical execution for the six announced indications for IMVT-1402, including a second potentially registrational study in Graves’ disease (GD) and a potentially registrational study in Sjögren’s disease (SjD), both expected to start in summer 2025

•Positive data from first-generation batoclimab trials in myasthenia gravis (MG) and chronic inflammatory demyelinating polyneuropathy (CIDP) demonstrated that deeper IgG reductions correlated with improved clinical outcomes across a range of assessments and timepoints suggesting a potential best-in-class efficacy profile for IMVT-1402

•Current cash balance provides runway for announced indications through GD readout expected in 2027

NEW YORK, May 29, 2025 – Immunovant, Inc. (Nasdaq: IMVT), a clinical-stage immunology company dedicated to enabling normal lives for people with autoimmune diseases, today reported corporate updates and financial results for its fourth quarter and fiscal year ended March 31, 2025.

In April 2025, Immunovant announced changes to its leadership team as part of a broader strategic transition with Roivant increasing operational involvement and oversight of Immunovant. Eric Venker, M.D. was appointed as CEO of Immunovant, and Tiago Girao as CFO of Immunovant. Given the strength of its potential best-in-class profile, IMVT-1402 is being developed in six announced indications, including potentially registrational trials in Graves’ disease (GD), difficult-to-treat rheumatoid arthritis (D2T RA), myasthenia gravis (MG), chronic inflammatory demyelinating polyneuropathy (CIDP) and Sjögren’s disease (SjD), and a proof-of-concept trial in cutaneous lupus erythematosus (CLE).

In March 2025, Immunovant announced positive results from its batoclimab MG and CIDP studies. The potentially registrational study in MG met its primary endpoint of change from baseline in Myasthenia Gravis Activities of Daily Living (MG-ADL) score in the AChR+ population at week 12, with the higher dose arm achieving a 5.6-point improvement (with 74% mean IgG reduction) and the lower dose arm achieving a 4.7-point improvement (with 64% mean IgG reduction). Initial results from week 12 of the Phase 2b CIDP study demonstrated a mean improvement in the adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability score of 1.8 across batoclimab arms and an 84% responder rate in those patients who achieved an IgG lowering greater than 70%. In both batoclimab studies, deeper IgG reductions correlated with improved clinical outcomes across a range of assessments and timepoints. Potentially registrational trials for IMVT-1402 in both MG and CIDP are actively enrolling.

In March 2025, Immunovant initiated a potentially registrational trial of IMVT-1402 in adult participants with active, anti-citrullinated protein autoantibody (ACPA) positive D2T RA and a proof-of-concept study in CLE. Both indications represent potential first-in-class and best-in-class opportunities based on positive in-class competitor data (D2T RA) and promising efficacy data from patients dosed with IMVT-1402 as part of an open-label case study program (CLE).

Immunovant plans to initiate a potentially registrational trial evaluating IMVT-1402 in SjD and a second potentially registrational trial in GD in the summer of 2025.

Immunovant expects to report batoclimab six-month remission data from the proof-of-concept study in GD in the summer of 2025 and Phase 3 thyroid eye disease (TED) data in the second half of calendar year 2025.

Cash Position: As of March 31, 2025, Immunovant’s cash and cash equivalents totaled approximately $714 million, providing runway for announced indications through GD readout expected in 2027.

R&D Expenses: Research and development expenses were $93.7 million for the three months ended March 31, 2025, compared to $66.1 million for the three months ended March 31, 2024. The increase was primarily due to activities related to our clinical trials of IMVT-1402, including contract manufacturing costs and elevated personnel-related expenses. The increase was partially offset by lower overall costs related to our IMVT-1402 Phase 1 trial and nonclinical studies.

G&A Expenses: General and administrative expenses were $20.2 million for the three months ended March 31, 2025, compared to $14.8 million for the three months ended March 31, 2024. The increase was primarily due to higher personnel-related expenses, information technology costs, legal and other professional fees, and market research costs.

Net Loss: Net loss was $106.4 million ($0.64 per common share) for the three months ended March 31, 2025, compared to $75.3 million ($0.52 per common share) for the three months ended March 31, 2024. Net loss for the three months ended March 31, 2025 and March 31, 2024 included $11.7 million and $9.7 million, respectively, related to non-cash stock-based compensation expense.

Common Stock: As of March 31, 2025, there were 170,111,593 shares of common stock issued and outstanding.

R&D Expenses: Research and development expenses were $360.9 million for the fiscal year ended March 31, 2025, compared to $212.9 million for the fiscal year ended March 31, 2024. The increase was primarily due to activities related to our clinical trials of IMVT-1402, including contract manufacturing costs, elevated personnel-related expenses, and higher overall clinical trial costs related to our batoclimab pivotal clinical trials. The increase was partially offset by lower overall costs related to our IMVT-1402 Phase 1 trial and nonclinical studies.

IPR&D Expenses: There were no acquired in-process research and development expenses for the fiscal year ended March 31, 2025. During the fiscal year ended March 31, 2024, acquired in-process research and development expenses were $12.5 million related to the achievement of development and regulatory milestones for batoclimab under the terms of the HanAll in-license agreement.

G&A Expenses: General and administrative expenses were $77.2 million for the fiscal year ended March 31, 2025, compared to $57.3 million for the fiscal year ended March 31, 2024. The increase was primarily due to higher personnel-related expenses, professional fees, information technology costs, and market research costs.

Net Loss: Net loss was $413.8 million ($2.73 per common share) for the fiscal year ended March 31, 2025, compared to $259.3 million ($1.88 per common share) for the fiscal year ended March 31, 2024. Net loss for the fiscal year ended March 31, 2025 and 2024 included $49.5 million and $41.1 million, respectively, related to non-cash stock-based compensation expense.
