CAMBRIDGE, Mass., April 30, 2020— Agios Pharmaceuticals, Inc. (NASDAQ: AGIO), a leader in the field of cellular metabolism to treat cancer and rare genetic diseases, today reported business highlights and financial results for the first quarter ended March 31, 2020. In addition, Agios provided an update on its response to the globalCOVID-19 pandemic and the expected impact on its business operations.

“Though there is no modern playbook for a crisis like theCOVID-19 pandemic, we moved quickly to reduce the risk of our team’s and communities’ exposure to the virus and took action to enable uninterrupted access to our commercial and clinical medicines for the patients who are counting on us,” said Jackie Fouse, Ph.D., chief executive officer at Agios.

“Despite the challenges we faced in the first quarter in the wake of theCOVID-19 pandemic, we made significant clinical and commercial progress, including completing enrollment in the ACTIVATE pivotal trial of mitapivat in PK deficiency, delivering strong TIBSOVO^® performance and achieving key U.S. and EU regulatory milestones. We have also made important resource allocation decisions with the goal of delivering on our key business objectives while conserving cash and increasing our financial flexibility,” continued Dr. Fouse. “Through these efforts, we remain on track to achieve our Agios 2025 strategic vision. As we have all worked to adapt to these unexpected and trying circumstances, the teamwork and resilience demonstrated by my colleagues has truly been remarkable and provides confidence that we will come out of these challenging times even stronger than we were before.”

FIRST QUARTER 2020 HIGHLIGHTS & RECENT PROGRESS

• TIBSOVO^® net sales increased by 16% and total number of unique prescribers expanded by 25% from the fourth quarter of 2019; this growth was driven largely by uptake in both the newly diagnosed and relapsed and refractory acute myeloid leukemia (AML) segments.

• Enrollment was completed in ACTIVATE, the ongoing pivotal trial of mitapivat in adults with pyruvate kinase (PK) deficiency who do not regularly receive transfusions.

• In March, mitapivat was issued a positive opinion on its application for orphan drug designation by the European Medicines Agency (EMA) Committee for Orphan Medicinal Products for the treatment of adults with PK deficiency.

• In March, Agios received clearance from the U.S. Food and Drug Administration (FDA) for its investigational new drug application forAG-946, a next generation PKR activator.

• Updated data from the Phase 1 study of vorasidenib innon-enhancinglow-grade glioma have been accepted for presentation at the 2020 American Society of Clinical Oncology (ASCO) Annual Meeting in May, which is being held virtually.

• Data from the Phase 2 study of mitapivat in thalassemia have been accepted for presentation at the European Hematology Association (EHA) Annual Congress in June, which will be held virtually.

COVID-19 RESPONSE & IMPACT ON BUSINESS OUTLOOK

TIBSOVO^®

To date, patient and physician demand for TIBSOVO^® (ivosidenib tablets) – an oral therapy for AML – has not been negatively impacted by theCOVID-19 pandemic. AML is a serious disease that progresses rapidly if untreated, and in most cases treatment delays are not recommended. Professional oncology guidelines for the treatment of cancer patients during the pandemic favor effective oral options with well tolerated safety profiles.

Based on current inventory levels and a robust supply chain strategy, Agios does not anticipate interruptions to supply of TIBSOVO^®, even if extended disruptions to manufacturing operations were to occur as a result of theCOVID-19 pandemic.

In addition, Agios has taken steps to ensure new and existing TIBSOVO^® patients can access the medication. TIBSOVO^® can be delivered directly to patients’ residences to ensure they can receive their medication even if they are homebound for a prolonged period of time. The myAgios^TM patient assistance program has remained a constant resource for patients, including those who have lost health insurance due to unemployment.

Based on these considerations, Agios continues to expect its 2020 TIBSOVO^® net U.S. revenue to be between $105 and 115 million.

Clinical Programs

Because hospitals globally have shifted resources to treat patients withCOVID-19, Agios expects some delays in its clinical programs based on anticipated challenges related to data collection, access to trial sites and patient enrollment.

In February, Agios established a clinical trial task force to ensure the safety of patients in its clinical trials and to support patients on acase-by-case basis to enable their continued participation in the studies. Where appropriate, Agios has instituted home visits, telemedicine approaches, the use of local laboratories and courier shipments of investigational medicines.

The status of each Agios clinical program, along with the expected impact ofCOVID-19, is outlined below. The ultimate extent of the impact of theCOVID-19 pandemic on clinical trial enrollment, continuation and data collection will depend on future developments, which are highly uncertain.

Rare Genetic Diseases

Research

• Agios remains on track to name a new development candidate by the end of the year.

• Agios conducted a prioritization exercise and made the decision to pause certain research programs, including its program in Friedreich’s Ataxia.

Cash Conservation Actions

In order to conserve cash while supporting the execution of critical business objectives during this period of uncertainty, Agios has made decisions to ceasein-house development ofAG-636; delay select research programs, including the Friedreich’s Ataxia program, and longer-term clinical studies; limit staff hiring and significantly reduce contract workforce; and pause certain infrastructure projects. Additional savings are anticipated across the business as a result of reduced spending levels that will occur naturally due to theCOVID-19 pandemic, such as travel expenses and clinical trial spend.

FIRST QUARTER 2020 FINANCIAL RESULTS

Revenue:Total revenue for the first quarter of 2020 was $87.1 million, which includes $22.7 million of net product revenue from sales of TIBSOVO^®, $61.1 million in collaboration revenue and $3.3 million in royalty revenue from net global sales of IDHIFA^® under the collaboration agreement with Celgene. This compares to revenue of $30.2 million for the first quarter of 2019.

The year-over-year increase in total revenue was primarily due to a $42.2 million increase in collaboration revenue. Aspreviously announced, Celgene declined to extend the metabolic immuno-oncology research collaboration with Agios. In addition, Celgene declined its option to designate one undisclosed research program for continued development andopt-in right. As a result, Agios recognized the majority of the deferred revenue during the first quarter of 2020. The remainder of the deferred revenue balance will be recognized in the second quarter of 2020 through the expiration of the research term inmid-May. The revenue increase was also driven by an increase of $13.5 million of net sales of TIBSOVO^®.

Cost of Sales: Cost of sales were $0.5 million for the first quarter of 2020 compared to $0.3 million for the first quarter of 2019.

Research and Development (R&D) Expenses: R&D expenses were $91.3 million for the first quarter of 2020 compared to $95.6 million for the first quarter of 2019. The decrease in R&D expenses was primarily due to the recognition of milestones for the initiation of the HOVON150/AMLSG29 study in the first quarter of 2019 and decreased activity for the ClarIDHy study and the Phase 1 hematologic malignancy study of TIBSOVO^®.

Selling, General and Administrative (SG&A) Expenses:SG&A expenses were $38.5 million for the first quarter of 2020 compared to $31.8 million for the first quarter of 2019. The increase in SG&A expenses were driven by higher personnel costs, including stock-based compensation expense, related to our workforce.

Net Loss:Net loss was $40.3 million for the first quarter of 2020 compared to $93.1 million for the first quarter of 2019.

Cash Position and Guidance:Cash, cash equivalents and marketable securities as of March 31, 2020 were $613.1 million compared to $707.8 million as of March 31, 2019.

As a result of the company’s cash conservation actions, the company expects that its cash, cash equivalents and marketable securities as of March 31, 2020, together with anticipated product and royalty revenue, anticipated interest income, and anticipated expense reimbursements under our collaboration and license agreements, but excluding any additional collaboration-related payments, will enable the company to fund its anticipated operating expenses and capital expenditure requirements through June 2022.
