Personalis experienced a challenging second quarter in 2025 with a significant revenue decline of 24% year-over-year, primarily due to expected decreases from Natera and a reduction in pharma tests and services. Despite these headwinds, the company demonstrated strong clinical adoption, with a 59% sequential increase in clinical test volume, driven by the NeXT Personal® platform and compelling clinical data presentations. The net loss widened compared to the previous year, and the gross margin decreased.
Total revenue for Q2 2025 was $17.2 million, a 24% decrease compared to $22.6 million in Q2 2024.
Clinical test volume saw a significant 59% sequential increase, with 3,478 clinical tests delivered in Q2 2025.
Gross margin declined to 27.6% in Q2 2025 from 35.6% in Q2 2024, primarily due to lower revenue volume and increased unreimbursed clinical test costs.
Net loss for Q2 2025 was $20.1 million, compared to a net loss of $12.8 million in Q2 2024.
