Management Comments

• "We are very happy to report the continuation of our positive earnings trend, which is driven by increased demand for NERLYNX."
• "According to our current projections, 2025 will mark the first year-over-year demand increase for NERLYNX in the United States since 2018 and we are very pleased with our commercial execution, which contributed to this."
• "We are also pleased with our continued clinical progress in the advancement of alisertib for patients facing chemotherapy-nave HER2-negative, hormone receptor-positive metastatic breast cancer in ALISCATM-Breast1 and for patients with extensive-stage small cell lung cancer in ALISCATM-Lung1, where there continues to be a need for new treatment."

Industry Context

Puma Biotechnology operates in the highly competitive biopharmaceutical sector, specifically focusing on oncology with its approved drug NERLYNX for HER2-positive breast cancer and alisertib in clinical development for breast and small cell lung cancer. The reported increase in U.S. demand for NERLYNX, a drug approved in 2017, indicates successful commercial execution in a mature market segment. The continued investment in alisertib's clinical trials for unmet needs in breast and lung cancer aligns with the industry trend of developing targeted therapies for specific patient populations.

Stakeholder Impact

• Shareholders: Positive impact from raised full-year guidance and continued clinical progress, potentially leading to increased share value.
• Patients: Continued access to NERLYNX through the Puma Patient Lynx program and potential future treatment options from alisertib development.
• Employees: Stable operations and continued R&D efforts suggest job security and ongoing work in drug development.
• Customers (Healthcare Providers): Continued availability and support for NERLYNX, with new data expected for alisertib.
• Creditors: Interest expense decreased, and working capital and equity improved, suggesting a stable financial position despite a slight decrease in cash.

Next Steps

• Host a conference call on November 6, 2025, at 1:30 p.m. PT/4:30 p.m. ET to discuss Q3 2025 financial results and business outlook.
• Present interim data from the ALISCA-Breast1 Phase II trial in H1 2026.
• Present additional interim data from the ALI-4201/ALISCA-Lung1 Phase II clinical trial in H1 2026.

Key Dates

Recommendation

While Puma Biotechnology has demonstrated strong commercial execution for NERLYNX in the U.S., leading to raised full-year 2025 guidance for revenue and net income, the third-quarter results showed a significant year-over-year decline in total revenue and GAAP net income, primarily due to reduced international sales and royalty revenue. The increase in R&D expenses for alisertib trials is a necessary investment for future growth, but the overall cash position has slightly decreased. The raised guidance is positive, but the mixed quarterly performance and ongoing R&D investments suggest a 'hold' position until further clarity on alisertib's clinical outcomes and sustained growth in overall revenue can be observed.
