• A strong financial position with approximately $1.3 billion in cash, cash equivalents, and marketable securities as of September 30, 2025.
• Advancement of a robust earlyand mid-stage pipeline, including tebapivat in sickle cell disease and LR-MDS, AG-236 in polycythemia vera, and AG-181 in phenylketonuria, offering future growth potential.

Negatives

• The mitapivat Phase 3 RISE UP trial in sickle cell disease showed a trend favoring mitapivat but did not meet statistical significance in the primary endpoint of annualized rate of sickle cell pain crises (SCPCs) and the key secondary endpoint of change from baseline in PROMIS Fatigue.
• AQVESME carries a Boxed Warning for hepatocellular injury and is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS).

Risks

• There is no guarantee that any product candidate will successfully commence or complete necessary preclinical and clinical development phases, or that development will successfully continue.
• There is no guarantee that any positive developments in the business will result in stock price appreciation.
• The content and timing of decisions made by regulatory authorities (e.g., U.S. FDA, EMA) can impact product development and approval.
• Results of clinical trials and preclinical studies, including subsequent analysis of existing data and new data, may differ from current expectations.
• The business, operations, strategy, goals, and anticipated milestones could be affected by pandemics or other public health emergencies.
• The ability to obtain and maintain requisite regulatory approvals and to enroll patients in planned clinical trials is uncertain.
• Unplanned cash requirements and expenditures could impact financial performance.
• Competitive factors may affect market share and profitability.
• The ability to obtain, maintain, and enforce patent and other intellectual property protection for product candidates is crucial.
• The ability to establish and maintain key collaborations is important for development and commercialization.
• Uncertainty exists regarding any royalty payments related to the sale of the oncology business or any milestone or royalty payments related to the in-licensing of AG-236, and the timing of such payments.
• The results and effectiveness of the use of cash and cash equivalents are uncertain.
• General economic and market conditions can impact the company's performance.

Future Outlook

Agios is focused on executing a high-impact U.S. launch for AQVESME in thalassemia, expanding its PK activation franchise into additional high-value indications like sickle cell disease and lower-risk myelodysplastic syndromes, and advancing its promising early-stage pipeline to diversify across hematologic and rare diseases. The company remains committed to disciplined capital allocation and operational efficiency to support long-term sustainability and achieve profitability.

Management Comments

• "In 2025, Agios delivered another year of strong and consistent execution across our portfolio, marking meaningful progress toward our goal of becoming a sustainable and diversified rare disease company."

Industry Context

Agios Pharmaceuticals operates in the specialized and high-value rare disease biopharmaceutical sector, with a strong foundation in hematology. The U.S. approval and launch of AQVESME for thalassemia position the company as a leader in treating hemolytic anemias, addressing a significant unmet medical need. The ongoing development of its PK activator franchise for sickle cell disease and myelodysplastic syndromes, alongside other early-stage assets, aligns with the broader industry trend of developing targeted, disease-modifying therapies for genetic and rare blood disorders. The focus on a scalable commercial model and disciplined capital allocation reflects the strategic approach often seen in successful rare disease companies aiming for long-term sustainability.

Comparison to Industry Standards

• AQVESME is the only FDA-approved medicine for anemia in both non-transfusion-dependent and transfusion-dependent alphaor beta-thalassemia, establishing a new standard of care in this indication.
• The potential for $1 billion in peak global sales for AQVESME and PK deficiency positions it as a significant orphan drug, comparable to other successful rare disease therapies.
• The $425,000 annual U.S. WAC for thalassemia is consistent with the pricing models for other high-value, innovative rare disease treatments.
• Mitapivat's proven mechanism of PK activation across multiple hemolytic anemias (PK deficiency, thalassemia, and showing benefits in sickle cell disease) demonstrates a broad applicability that is highly valued in drug development.
• The company's strong cash position of $1.3 billion provides a robust financial foundation, which is a competitive advantage in the capital-intensive biopharmaceutical industry.

Stakeholder Impact

• Shareholders: Potential for increased revenue and profitability from the AQVESME launch and pipeline advancements, but also subject to clinical trial risks and regulatory hurdles.
• Patients (Thalassemia): Gaining access to a new, disease-modifying oral treatment (AQVESME) for anemia, offering a significant improvement in care.
• Patients (Sickle Cell Disease, LR-MDS, PV, PKU): Hope for new treatment options as pipeline candidates progress through clinical trials.
• Employees: Continued focus on commercial launch and R&D activities, supporting job stability and growth within the company.
• Regulatory Authorities: Ongoing engagement with the FDA for sNDA submission and implementation of the REMS program for AQVESME.

Next Steps
