Exhibit 99.1
Nautilus Biotechnology Reports Fourth Quarter and Fiscal Year 2023 Financial Results
SEATTLE, WA, February 28, 2024 – 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, 2023.

“2023 was a year of significant accomplishment and foundational progress for Nautilus; progress that will continue to build our momentum as we move through 2024 and into the planned launch of our proteome analysis platform”, said Sujal Patel, CEO of Nautilus. “We are building a groundbreaking, ‘first-in-the-world’ platform designed to unlock significant breakthroughs in biological research. Doing so requires that a number of meaningful innovations across each element of our platform - consumables, instrument, and software - weave together seamlessly. We continue to refine each of these platform elements and look forward to getting the collective work of our team into the hands of researchers where it can do so much good. I’m particularly pleased that we’ve been able to drive such meaningful scientific progress while maintaining exceptional fiscal discipline and preserving our balance sheet.”
Fiscal Year 2023 Financial Results
Operating expenses were $76.2 million for the year ended December 31, 2023, a $12.5 million or 20% increase from $63.6 million for the year ended December 31, 2022. The increase in operating expenses was driven primarily by an increase in headcount to support ongoing development of our products.
Net loss was $63.7 million for the year ended December 31, 2023, as compared to a net loss of $57.9 million for the corresponding prior year period.
Cash, cash equivalents, and investments were $264.1 million as of December 31, 2023.

Fiscal Year 2024 Outlook
We expect full year operating expense to grow by approximately 25% relative to 2023
We expect that cash and cash equivalents and investments of $264.1 million as of December 31, 2023 to provide a runway into the second half of 2026
We expect to launch our platform, instruments, consumables, and software in 2025.

Special Note Regarding Forward-Looking Statements
This press release contains forward-looking statements within the meaning of federal securities laws. Forward-looking statements in this press release include, but are not limited to, statements regarding Nautilus’ expectations regarding the company’s business operations, financial performance and results of operations; expectations with respect to any revenue timing or projections, expectations with respect to 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 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
1


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. For a more detailed description of additional risks and uncertainties facing Nautilus and its development efforts, investors should refer to the information under the caption “Risk Factors” in our Annual Report on Form 10-K to be filed for the year ended December 31, 2023 and our other filings with the SEC. The forward-looking statements in this press release are as of the date of this press release. Except as otherwise required by applicable law, Nautilus disclaims any duty to update any forward-looking statements. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this press release.
