• Achieved record net product sales of $72.3 million, a 13% year-over-year increase driven primarily by the successful commercial launch of VEPPANU in mid-August.

• Leveraged existing commercial and medical infrastructure to integrate VEPPANU within two months of licensing, resulting in $6.6 million in sales during its first six weeks of availability.

• Positioned VEPPANU as a differentiated therapeutic option by highlighting its PROTAC mechanism, which achieves 79% to 86% estrogen receptor degradation compared to 8% to 68% for traditional oral SERDs.

• Demonstrated strong early market access with an 88% prior authorization approval rate and a median time-to-fill of just four days through specialty pharmacy partners.

• Maintained a profitable quarter while simultaneously funding the launch of a fourth commercial product and advancing the R289 clinical development program.

• Reported record demand for TAVALISSE eight years post-launch, though management expects future growth to be primarily driven by the VEPPANU and R289 engines.

• Observed high adoption in the community oncology setting, which currently accounts for 70% to 80% of VEPPANU's early prescriber and account base.

Pipeline Advancement and 2027 Outlook

• On track to complete enrollment and select the recommended Phase 2 dose for R289 in lower-risk MDS by the end of 2026, with a registrational program planned for 2027.

• Anticipates R289 has the potential to be a $1 billion-plus commercial opportunity in the lower-risk MDS indication if clinical data supports FDA approval.

• Expects to present preliminary efficacy data from the R289 dose expansion phase at the ASH meeting in December, focusing on heavily pretreated patients who failed prior therapies.

• Plans to initiate exploratory cohorts for R289 in earlier lines of therapy to evaluate its potential in patients who are refractory to or ineligible for erythropoiesis-stimulating agents.

• Maintains guidance for full-year 2026 profitability while narrowing total revenue expectations to a range of $290 million to $295 million.

Operational and Financial Context

• Narrowed non-VEPPANU product sales guidance to $255 million to $260 million, reflecting record demand offset by gross-to-net adjustments and inventory variables.

• Increased cost of product sales to $10.8 million due to amortization of intangible assets from the VEPPANU transaction and royalties owed to Arvinas and Pfizer.

• R289 received FDA Fast Track and Orphan Drug designations for previously treated transfusion-dependent lower-risk MDS.

• Reported a decrease in GAVRETO sales by 11% year-over-year, though management views it as a stable contributor within the broader oncology portfolio.
