Overview We are a clinical-stage biopharmaceutical company focused on the development and commercialization of seralutinib for the treatment of pulmonary hypertension, or PH, including pulmonary arterial hypertension, or PAH, and PH 3 Table of Contents
These concentrations of patients could allow us to commercialize seralutinib with a relatively small commercial footprint, if approved. Seralutinib (PDGFR, CSF1R and c-KIT Inhibitor) Seralutinib, also known as GB002, is an investigational inhaled, small molecule, platelet-derived growth factor receptor, or PDGFR, colony-stimulating factor 1 receptor, or CSF1R, and c-KIT inhibitor, currently being evaluated in a Phase 3 clinical trial for the treatment of PAH. We believe that seralutinib has the potential to reverse pathological remodeling by addressing mechanisms that underlie PAH. Inhaled seralutinib, which is designed to act on both isoforms of the PDGFR, α and β, as well as the CSF1R and c-KIT pathways, inhibited and reversed cellular overgrowth in lung blood vessels in multiple animal PAH models.

Overview We are a clinical-stage biopharmaceutical company focused on the development and commercialization of seralutinib for the treatment of pulmonary hypertension, or PH, including pulmonary arterial hypertension, or PAH, and PH 3 Table of Contents
Critical components of our business strategy include: •Complete the ongoing Phase 3 PROSERA Study of seralutinib in PAH and pursue regulatory approval. We commenced the registrational Phase 3 PROSERA Study in PAH in the fourth quarter of 2023. We expect to report topline data from the PROSERA study in the fourth quarter of 2025. If the clinical trial is successful, we will seek marketing approval for seralutinib in the United States. •Increase the impact of seralutinib by expanding development into PH indications of high unmet need. We believe that not only does seralutinib offer potential as a therapeutic option for the treatment of PAH but also for the treatment of other rare PH indications of high unmet need, including PH-ILD. To that end, we expect to activate clinical sites for a global registrational Phase 3 for the treatment of PH-ILD in the second half of 2025.

We accelerate the impact of our portfolio by cultivating connections with patient communities, healthcare professionals, partners and colleagues to discover, develop and deliver potential therapies for rare diseases. Business Overview Rare diseases The lead product candidate in our portfolio, PYRUKYND® (mitapivat), is an activator of both wild-type and mutant pyruvate kinase, or PK, enzymes for the potential treatment of hemolytic anemias. PYRUKYND® is approved for use by the U.S. Food and Drug Administration, or FDA, for the treatment of hemolytic anemia in adults with PK deficiency in the United States and by the European Commission for the treatment of PK deficiency in adult patients in the European Union, or EU.
Revenues Our wholly owned product, PYRUKYND®, received approval from the FDA on February 17, 2022, for the treatment of hemolytic anemia in adults with PK deficiency in the United States. Upon FDA approval of PYRUKYND® in the United States, we began generating product revenue from sales of PYRUKYND®. We sell PYRUKYND® to a limited number of specialty distributors and specialty pharmacy providers, or collectively, the Customers. These Customers subsequently resell PYRUKYND® to pharmacies or dispense PYRUKYND® directly to patients. In addition to distribution agreements with Customers, we enter into arrangements with healthcare providers and payors that provide for government-mandated and/or privately-negotiated rebates, chargebacks and discounts with respect to the purchase of PYRUKYND®.

Also in December 2024, we announced that we submitted a marketing authorization application, or MAA, to the European Medicines Agency, or EMA, and regulatory applications to the Kingdom of Saudi Arabia and United Arab Emirates health authorities for PYRUKYND® for the treatment of adult patients with non-transfusion dependent and transfusion-dependent alpha- or beta-thalassemia. In addition, we are currently evaluating PYRUKYND® in Phase 3 clinical trials for the treatment of sickle cell disease, or SCD, and in pediatric patients with PK deficiency. We are also developing (i) tebapivat, a novel PK activator, for the potential treatment of lower-risk myelodysplastic syndromes, or LR MDS, and hemolytic anemias; (ii) AG-181, our phenylalanine hydroxylase, or PAH, stabilizer for the potential treatment of phenylketonuria, or PKU; and (iii) AG-236, an siRNA in-licensed 3 Table of Contents
Reducing the level of 2,3-DPG in RBCs would increase the oxygenation state of hemoglobin to reduce sickling, while increasing the levels of ATP may improve RBC hydration status which may also inhibit the sickling process. Lower Risk MDS (LR MDS) MDS is a heterogeneous group of rare hematological malignancies characterized by dysfunctional hematopoiesis (or formation of blood cells), progressive cytopenia (or lower-than-normal number of blood cells) and an increased risk of progression to acute myeloid leukemia, or AML. The most common type of MDS is LR MDS, but many existing therapies and therapies under development focus on high risk MDS. Among patients with LR MDS, which accounts for approximately 70% of all MDS cases and are less likely to progress to AML, the primary concern is symptomatic anemia.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.
