Blueprint Medicines' 2024 Earnings: EPS Beat Driven by AYVAKIT's Strong Performance and Growing SM Market

Blueprint Medicines Corporation (NASDAQ: BPMC) reported its most recent earnings on February 13, 2025, for Q4 2024, posting earnings per share (EPS) of -$0.79. This exceeded analysts' expectations of -$0.71 by 11.27%, marking a Miss. For comparison, Blueprint Medicines reported EPS of -$1.82 in the same quarter last year.

The company's earnings beat can be attributed to several factors, including the strong performance of its flagship product, AYVAKIT, and the growing market for systemic mastocytosis (SM) treatments.

AYVAKIT, a breakthrough medicine for patients with systemic mastocytosis, achieved $479.0 million in net product revenues for the full year 2024, representing 135% growth year-over-year. In the fourth quarter of 2024, AYVAKIT generated $144.1 million in net product revenues, contributing significantly to the company's overall earnings. The deep and sustained clinical impact of AYVAKIT, along with its strong safety profile, has transformed the treatment paradigm in ISM, driving its impressive revenue growth.

The growing market for SM treatments has also contributed to Blueprint Medicines' earnings beat. The company estimates that it has penetrated less than 10% of the existing pool of diagnosed SM patients, leaving significant headroom for growth. The number of diagnosed SM patients has been consistently growing at double-digit rates over the last five years, reaching over 25,000 patients in the U.S. as of 2024. This growth is driven by increased awareness and clinical suspicion of SM among providers, as well as the establishment of commercial testing infrastructure.

New epidemiology data published in 2024 suggests a twofold increase in the number of SM patients relative to prior estimates, bringing the number of potential SM patients in the U.S. up from approximately 30,000 patients to 60,000 patients. Additionally, Blueprint Medicines' real-world experience has shown that SM patients are being diagnosed by a broader range of providers than initially expected, including medical dermatologists and gastroenterologists. As these providers become more active in looking for ISM patients, they are finding them in their practices and building their expertise in managing these patients.

Blueprint Medicines' updated peak SM franchise opportunity of $4 billion reflects the company's confidence in the growing market for systemic mastocytosis treatments and the potential for AYVAKIT to capture a significant share of that market. To achieve this goal, the company is implementing several strategic initiatives, including expanding the diagnosed patient pool, growing the SM patient pool, innovating beyond symptom control, and diversifying the pipeline.

In conclusion, Blueprint Medicines' 2024 earnings beat was driven by the strong performance of AYVAKIT and the growing market for SM treatments. The company's updated peak SM franchise opportunity of $4 billion reflects its confidence in the long-term growth potential of the SM market and its commitment to driving sustainable growth through strategic initiatives. As the company continues to execute on its growth strategy, investors should monitor its progress and consider the potential benefits and risks associated with its long-term growth prospects.
