Upcoming Program Highlights*

• NX-2127: Nurix's lead drug candidate from its protein degradation portfolio, NX-2127, is an orally bioavailable degrader of BTK with immunomodulatory drug (IMiD) activity for the treatment of relapsed or refractory B-cell malignancies. Nurix is conducting its Phase 1 clinical trial of NX-2127 at multiple clinical sites. Initial pharmacokinetic (PK) and pharmacodynamic (PD) data from the dose escalation portion of the trial is anticipated by year-end 2021.

Fiscal Third Quarter 2021 Financial Highlights

Collaboration revenue for the three months ended August 31, 2021 was $10.3 million compared to $4.1 million for the three months ended August 31, 2020. The increase was due to the continued scale up of internal resources and external spending for our collaborations with Sanofi and Gilead as compared to the prior period, resulting in a higher percentage of completion in the current period. The increase was also due to partial revenue recognized during the three months ended August 31, 2021 for the achievement of certain preclinical milestones under our collaborations with Gilead and Sanofi.

Research and development expenses for the three months ended August 31, 2021 were $30.9 million compared to $18.9 million for the three months ended August 31, 2020. The increase was primarily related to an increase of $4.1 million in compensation and related personnel costs attributable to an increase in headcount. There was also an increase of $1.6 million in non-cash stock-based compensation expense. In addition, there was an increase of $1.9 million in supplies and contract research and an increase of $1.8 million in preclinical activities and contract manufacturing attributable to increases in our preclinical development activities and drug discovery research and an increase of $1.5 million in clinical costs due to ongoing clinical trial startup and patient enrollment.

General and administrative expenses for the three months ended August 31, 2021 were $8.3 million compared to $4.3 million for the three months ended August 31, 2020. The increase was primarily related to an increase of $1.2 million in compensation related expenses attributable to a higher headcount and an increase of $1.6 million in non-cash stock-based compensation expense. There was also an increase of $0.9 million in consultant and other professional service expenses primarily related to becoming a public company.

Net loss for the three months ended August 31, 2021 was $28.8 million, or ($0.65) per share, compared to a net loss of $18.5 million for the three months ended August 31, 2020, or ($1.09) per share.

Cash, Cash Equivalents and Investments: As of August 31, 2021, Nurix had cash, cash equivalents and investments of $465.4 million compared to $372.0 million as of November 30, 2020. The increase was primarily attributable to the net proceeds of $150.2 million from Nurix's follow-on offering in March 2021.
