Nautilus Biotechnology Reports Second Quarter 2025 Financial Results

SEATTLE, July 31, 2025 (GLOBE NEWSWIRE) -- Nautilus Biotechnology, Inc. (NASDAQ: NAUT; or 鈥淣autilus鈥�), a company pioneering a single-molecule proteome analysis platform, today reported financial results for the second quarter ended June听30, 2025.

鈥淚n Q2, we achieved major milestones that underscore the continued advancement of our platform,鈥� said Sujal Patel, CEO of Nautilus Biotechnology. 鈥淣ot only did we continue our momentum across both targeted and broadscale proteomic development efforts, but we also publicly shared the first scientific manuscript to feature novel data generated using the Nautilus Platform. The manuscript represents nearly a decade of pioneering work by our team and collaborators. In it, we introduce and validate application of our Iterative Mapping method showing that it can measure proteoforms at a resolution and breadth never before possible.

鈥淲e have also signed two collaborations with major research institutes to utilize the Nautilus platform and Tau proteoform assay. Through studies of co-incident post-translational modifications on Tau across brain regions in human tissue and across models of Alzheimer's disease progression we aim to enable researchers to make fundamental advances in understanding disease-relevant biology. Together, these achievements represent both the demonstration and external recognition of the exceptional performance of our platform and mark a critical step toward enabling researchers to uncover proteomic insights that we believe will shape the future of biomarker and therapeutic discovery.鈥�

Second Quarter 2025 Financial Results

Operating expenses were $17.1 million for the second quarter of 2025, a 18% decrease compared to $20.8 million for the corresponding prior year period. The decrease in operating expense is attributable to continued focus on cost optimization, variability in the timing of research and development activities, and decreased salaries, related benefits, stock-based compensation, and professional services expenses.

Net loss was $15.0 million for the second quarter of 2025, as compared to the net loss of $18.0 million for the corresponding prior year period.

Cash, cash equivalents, and investments were $179.5 million as of June听30, 2025.
