Nautilus Biotechnology Reports Fourth Quarter and Fiscal Year 2024 Financial Results
SEATTLE, WA, February 27, 2025 – Nautilus Biotechnology, Inc. (NASDAQ: NAUT; or “Nautilus”), a company pioneering a single-molecule proteome analysis platform, today reported financial results for the fourth quarter and fiscal year ended December 31, 2024.

Reported total operating expenses for the fourth quarter of 2024 were $20.0 million, roughly equal to the fourth quarter of 2023, and $0.9 million above last quarter reflecting an ongoing focus on expense management;
Announced an expectation that the launch of Nautilus’ proteome analysis platform - instruments and reagents - will occur in late 2026;
Announced a reduction in headcount of approximately 16% in order to appropriately align the resources needed to pursue key development goals with the desire to extend the company’s cash runway.

“2024 was a year of innovation and meaningful accomplishment for Nautilus,” said Sujal Patel, CEO of Nautilus Biotechnology. “From unveiling the world’s first quantitative measurement of biological variation in tau proteoforms potentially associated with Alzheimer’s Disease, to fundamental platform development advancements, I’m pleased with the progress of last year. Our revised timeline expectations for commercial launch are based on efforts required to implement modifications to our platform’s assay configuration and surface chemistry that we believe will significantly reduce technical risk and yield the greatest possible platform performance.”
Fourth Quarter 2024 and Fiscal Year 2024 Financial Results
Operating expenses were $20.0 million for the three months ended December 31, 2024, flat compared to $20.0 million for the three months ended December 31, 2023. Operating expenses were $81.5 million for the year ended December 31, 2024, a $5.3 million or 7% increase from $76.2 million for the year ended December 31, 2023. The increase in operating expense is attributable to continued headcount growth throughout the year to support product development.
Net loss was $17.6 million for the fourth quarter of 2024, as compared to the net loss of $17.0 million for the corresponding prior year period. Net loss was $70.8 million for the year ended December 31, 2024, as compared to the net loss of $63.7 million for the year ended December 31, 2023.
Cash, cash equivalents, and investments were $206.3 million as of December 31, 2024.

Fiscal Year 2025 Outlook
In 2025, we expect operating expenses to be at or below 2024 levels.
We expect that cash, cash equivalents and investments of $206.3 million as of December 31, 2024 will provide a runway through 2027.

required for and the timing of the launch of Nautilus’ product platform and full commercial availability, the functionality and performance of Nautilus’ product platform, its potential impact on providing proteome or proteoform access, pharmaceutical development and drug discovery, expanding research horizons, and enabling scientific explorations and discovery, and the present and future capabilities and limitations of emerging proteomics technologies. These statements are based on numerous assumptions concerning the development of Nautilus’ products, target markets, and other current and emerging proteomics technologies, and involve substantial risks, uncertainties and other factors that may cause actual results to be materially different from the information expressed or implied by these forward-looking statements. Risks and uncertainties that could materially affect the accuracy of Nautilus’ assumptions and its ability to achieve the forward-looking statements set forth in this press release include (without limitation) the following: Nautilus’ product platform is not yet commercially available and remains subject to significant scientific and technical development, which is inherently challenging and difficult to predict, particularly with respect to highly novel and complex products such as those being developed by Nautilus. Even if our development efforts are successful, our product platform will require substantial validation of its functionality and utility in life science research. In the course of Nautilus’ scientific and technical development and associated product validation and commercialization, we may experience material delays as a result of unanticipated events. We cannot provide any guarantee or assurance with respect to the outcome of our development, collaboration, and commercialization initiatives or with respect to their associated timelines.
