Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based on Disc’s current beliefs, expectations and assumptions regarding the future of Disc’s business, future plans and strategies, clinical results and other future conditions.

Disc may not actually achieve the plans, intentions or expectations disclosed in these forward-looking statements, and investors should not place undue reliance on these forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements as a result of a number of material risks and uncertainties including but not limited to: the adequacy of Disc’s capital to support its future operations and its ability to successfully initiate and complete clinical trials; the nature, strategy and focus of Disc; the difficulty in predicting the time and cost of development of Disc’s product candidates; Disc’s plans to research, develop and commercialize its current and future product candidates; the timing of initiation of Disc’s planned preclinical studies and clinical trials; the timing of the availability of data from Disc’s clinical trials; Disc’s ability to identify additional product candidates with significant commercial potential and to expand its pipeline in hematological diseases; the timing and anticipated results of Disc’s preclinical studies and clinical trials and the risk that the results of Disc’s preclinical studies and clinical trials may not be predictive of future results in connection with future studies or clinical trials and may not support further development and marketing approval; the content and timing of decisions made by the FDA and other regulatory authorities; final audit adjustments and other developments that may arise that would cause Disc’s expectations with respect to the estimate of cash, cash equivalents and marketable securities as of December 31, 2025 to differ, perhaps materially, from the financial results that will be reflected in Disc’s audited consolidated financial statements for the fiscal year ended December 31, 2025; and the other risks and uncertainties described in Disc’s filings with the Securities and Exchange Commission, including in the “Risk Factors” section of Disc’s Annual Report on Form 10-K for the year ended December 31, 2024, and in subsequent Quarterly Reports on Form 10-Q.

Agenda Introduction Overview: Bitopertin for EPP Bitopertin Launch Strategy Pipeline Programs 2026/2027 Corporate Outlook Q&A

Hepcidin is a Therapeutic Target for Diseases Dysregulated hepcidin drives a wide range of hematologic diseases Anemias of Inflammatory Disease Myelofibrosis Autoimmune / Inflammatory Disorders Iron Overload and Excess Red Blood Cell Disorders Polycythemia Vera Sickle Cell Disease High Hepcidin Normal Hepcidin Low Hepcidin Regulated erythropoiesis Regulated iron Restricted Iron Iron Overload DISC-0974 (anti-HJV mAb) Reduce Hepcidin / Increase Iron DISC-3405 (anti-TMPRSS6 mAb) Induce Hepcidin / Restrict Iron

DISC-0974: Novel Anti-HJV mAb to Suppress Hepcidin HJV = hemojuvelin Designed to enhance iron availability to address a wide range of hematologic disorders Releases iron stores Enables GI absorption Increases Iron Reduces Hepcidin Inhibits endogenous production of hepcidin Potential to treat wide range of anemias Enables RBC Production

Myelofibrosis Opportunity CONFIDENTIAL Positioned for use across all anemia MF patients, regardless of background MF-directed therapy, setting up for a potential blockbuster opportunity ~$2.0B Total Est. 2024 JAK Inhibitor US Sales (MF) DISC-0974 target profile is designed to address the full MF anemia market: ~22K Addressable Patients Implies >$4B US Opportunity MF patients treated with JAK inhibitor MF patients JAK-naïve or discontinued 25K US MF patients 87% Anemic Significant Unmet Need for Anemia-Focused Therapy Anemia is associated with worse disease prognosis and survival; impacts patient QOL and healthcare utilization Limits or contributes to failure of treatment with JAK inhibitors Current FDA-approved MF therapies focus on managing symptoms and spleen, not anemia Off-label anemia management tools are limited by efficacy, applicability, and tolerability Thinning of the competitive pipeline sets up the potential for DISC-0974 to be the primary therapy to address MF anemia for all anemic patients

Initial RALLY-MF Phase 2 Data CONFIDENTIAL Positive, durable benefits on hemoglobin and transfusion burden in anemia of MF across a broad range of patients Hematologic Response Hepcidin by Transfusion Cohort Iron by Transfusion Cohort nTD TD Low TD High Abbreviations:. 6 nTD, 3 TD Low participants were considered non-evaluable due incomplete data entry at the time of data cut. 10 participants had a per protocol dose escalation at visit Day 57 due to insufficient response. 4 participants had a per protocol dose hold due to Hgb >12 g/dL. 68% of participants who completed study are participating in the optional continuation phase.; Overall response for NTD = Mean Hgb ↑ ≥1 g/dL for ≥12 weeks, for TD Low and TD High = ≥50% reduction in transfusion requirement; Major response for NTD = Mean Hgb ↑ ≥1.5 g/dL for ≥12 weeks, for TD Low = TI ≥16 weeks, and for TD High = TI ≥12 weeks

Initial RALLY-MF Phase 2 Data CONFIDENTIAL nTD and TD Low patients had meaningful responses on hemoglobin and FACIT-Fatigue with greatest improvements seen in those achieving a major hematologic response Hemoglobin analysis excludes values within 14 days from receipt of PRBC transfusion. * A 3-point change in the FACIT-Fatigue score was used as a threshold for clinical significance. Source: Webster et al, Health Qual Life Outcomes. 2003;1:79. Hemoglobin FACIT-Fatigue Hemoglobin FACIT-Fatigue Mean Change from Baseline Over Time nTD TD Low

Initial RALLY-MF Phase 2 Data CONFIDENTIAL DISC-0974 has demonstrated efficacy regardless of concomitant JAK inhibitor use, setting up for utilization across all anemic MF patients Response by JAKi Cohort Abbreviations: Hgb = hemoglobin; JAKi = JAK inhibitor; mmb = momelotinib; pac = pacritinib; rux = ruxolitinib; TI = transfusion independence. 6 nTD, 3 TD Low, and 4 TD High participants were considered non-evaluable due incomplete data entry at the time of data cut. 10 participants had a per protocol dose escalation at visit Day 57 due to insufficient response. 4 participants had a per protocol dose hold due to Hgb >12 g/dL. 68% of participants who completed study are participating in the optional continuation phase.

Anti-HJV Franchise: Next Steps and Future Development CONFIDENTIAL Additional RALLY-MF data expected H2 2026 End of Phase 2 Meeting with FDA expected H2 2026 Phase 3 Pivotal trial initiation expected H1 2027 Anemia of Myelofibrosis Signal-seeking Phase 2 study in anemia of IBD with DISC-0974 expected to initiate early 2026 Exploratory work in additional anemia indications Continued IND-enabling activities for the long-acting anti-HJV (DISC-0998) Other Anemias of Inflammation

Anti-TMPRSS6 mAb Induces Hepcidin Designed to limit iron levels with potential to address a wide range of hematologic disorders Promotes Iron Restriction Decreases GI Absorption Limits Iron Availability Increases Hepcidin Enables Endogenous Production of Hepcidin Erythrocytosis (PV) Ineffective Erythropoiesis Iron Overload Modulates RBC Production

DISC-3405: Polycythemia Vera Opportunity CONFIDENTIAL Multi-billion-dollar market with significant unmet need for an effective, safe, and convenient treatment to maintain HCT <45% Polycythemia Vera ~150,000 US Patients ~75k treated patients; significant room for market development; operational synergies with MF treaters Treatments offer suboptimal HCT control, leading to increased risk of thrombotic events and other potential symptoms Targeting hepcidin has been shown to control HCT while reducing/eliminating phlebotomy and improving symptoms Attractive Market Clear Unmet Need Validated Mechanism Favorable Presentation Target profile of monthly subcutaneous dosing with favorable safety / tolerability and no injection site reactions to-date DISC-3405 Positioning Phlebotomy Hydroxyurea Ruxolitinib Interferon Current Treatment Options DISC-3405 is expected to be able to be used across the treatment landscape for PV

DISC-3405 Healthy Volunteer Data CONFIDENTIAL In healthy volunteers, DISC-3405 significantly increases hepcidin and decreases in iron, leading to reductions in hemoglobin and hematocrit that are expected to be beneficial in PV patients PK/PD: 300 mg SC SAD PK/PD: 150 mg SC MAD Dose 1 Dose 2 Hemoglobin Hematocrit 150 SC, MAD 300 SC, SAD Data expected in H2 2026 for the ongoing Phase 2 PV study and Phase 1b SCD study of DISC-3405
