Fiscal Second Quarter 2026 Financial Results

Revenue for the three months ended May 31, 2026, was $9.0 million compared with $44.1 million for the three months ended May 31, 2025. The decrease was primarily due to $30 million of license revenue from two Sanofi license extensions in the prior year. During the three months ended May 31, 2026, Nurix achieved a research milestone under its collaboration with Sanofi of $2 million.

Research and development expenses for the three months ended May 31, 2026, were $87.7 million compared with $78.1 million for the three months ended May 31, 2025. The increase was primarily related to clinical costs and contract manufacturing costs as Nurix continued to accelerate the enrollment of patients in the ongoing Phase 2 trial of bexobrutideg and to enable the initiation of Phase 3 trials.

General and administrative expenses for the three months ended May 31, 2026, were $15.6 million compared with $14.3 million for the three months ended May 31, 2025. The increase was primarily due to an increase in legal costs for collaboration and business development activities.

Net loss for the three months ended May 31, 2026, was $89.5 million or ($0.81) per share compared with $43.5 million or ($0.52) per share for the three months ended May 31, 2025.

Cash, cash equivalents and marketable securities were $443.5 million as of May 31, 2026, compared to $592.9 million as of November 30, 2025. In addition, we expect to receive the $700 million upfront payment from Roche in the third fiscal quarter of 2026.
