Company Overview
Nautilus Biotechnology, Inc. (NAUT) is a development stage life sciences company that is pioneering a revolutionary single-molecule protein analysis platform aimed at decoding and quantifying the human proteome. With its corporate headquarters in Seattle, Washington and research and development facilities in San Carlos, California, Nautilus is leading the charge to transform the field of proteomics and enable groundbreaking advancements across human health and medicine.
Founded in 2016, Nautilus has dedicated itself to overcoming the limitations of existing proteomics technologies and developing a platform capable of comprehensively mapping the proteome with unparalleled sensitivity, speed, and accuracy. The human proteome, comprising an estimated 6 million unique protein variants, is a vastly complex and dynamic landscape that holds the key to unlocking a deeper understanding of biological processes, identifying novel drug targets, and uncovering diagnostic biomarkers. However, current proteomics tools have struggled to provide researchers with the ability to reliably and efficiently explore this intricate protein universe.
Research and Development
Since its inception, Nautilus has devoted substantially all of its resources to research and development activities, including the development of its proteomics platform, business planning, establishing and maintaining its intellectual property portfolio, hiring personnel, raising capital, and providing general and administrative support for these operations. The company's journey has been marked by significant milestones in funding and strategic partnerships.
Funding and Strategic Partnerships
Prior to 2021, Nautilus funded its operations primarily through the sale of convertible preferred stock, raising net proceeds of $108.4 million from private placements. A pivotal moment came in June 2021 when Nautilus completed a Business Combination with ARYA Sciences Acquisition Corp III. This transaction, along with investments from PIPE (Private Investment in Public Equity) investors, resulted in gross proceeds of approximately $345.5 million, offset by $18.2 million in transaction costs and underwriter fees.
To validate the utility of its platform and generate valuable data, Nautilus has entered into several key research collaboration agreements. In 2020, the company partnered with Genentech for a pilot study using Nautilus' technology to investigate proteoforms of the Tau protein, an important biomarker of neurodegenerative disease. Building on this momentum, Nautilus established additional research collaborations in 2021 with Amgen, The University of Texas MD Anderson Cancer Center, and The Buck Institute for Research on Aging.
Technology Platform
Nautilus' innovative approach centers around a single-molecule detection technology that can identify and quantify substantially all proteins within a sample, including the diverse array of post-translational modifications that play a critical role in determining protein function. By leveraging advanced computer science, engineering, and biochemistry, the company has developed a proteome analysis system capable of rapidly and reproducibly detecting protein molecules at the individual level, overcoming the limitations of bulk measurement techniques that have constrained the field of proteomics.
The Nautilus platform is designed to deliver two distinct, yet complementary, modalities: broad-scale discovery proteomics and targeted proteoform analysis. The broad-scale discovery capabilities aim to decode the vast majority of the proteome, providing researchers with an unprecedented view of the protein landscape and enabling the identification of novel biomarkers and drug targets. In parallel, the targeted proteoform analysis functionality allows for the deep characterization of specific proteins of interest, such as tau, which has been implicated in neurodegenerative diseases like Alzheimer's.
Recent Developments
Through strategic partnerships with leading biopharmaceutical companies and academic institutions, Nautilus has been making steady progress in validating the performance and utility of its platform. In 2024, the company presented data at scientific conferences demonstrating its ability to achieve yoctomole-level sensitivity, quantify protein isoforms and post-translational modifications with high accuracy and reproducibility, and successfully decode proteins from a diverse range of organisms.
Despite the advancements made, Nautilus recently announced a delay in the commercial launch of its proteome analysis platform, now expected in late 2026. This decision was driven by the company's commitment to reducing technical risk and optimizing the platform's performance, with a focus on enhancing the robustness of its affinity reagents and assay configuration. While disappointing in the near-term, Nautilus believes this approach will position the company to deliver a truly transformative product to the market.
Financials
Financially, Nautilus has maintained a disciplined approach to managing its expenses, with total operating costs of $81.5 million in fiscal year 2024, a 7% increase from $76.2 million in the prior year. The company's net loss for the year was $70.8 million, up 11% year-over-year from $63.7 million in 2023. Research and development expenses accounted for the majority of operating expenses, totaling $50.5 million in 2024, a 7% increase from $47.3 million in 2023. This increase was primarily driven by higher salaries, related benefits, and stock-based compensation due to increased headcount, as well as increased in-process research and development expenses and laboratory supplies and equipment costs.
General and administrative expenses were $31.0 million in 2024, compared to $28.9 million in 2023, also a 7% increase. This increase was mainly attributable to higher professional services costs, including legal and consulting fees, as well as increased facilities costs and salaries, related benefits, and stock-based compensation.
For the most recent quarter (Q4 2024), Nautilus reported no revenue and a net loss of $17.6 million. The company has not yet commercially launched its platform and does not have any products available for sale, nor has it generated any revenue since inception.
To extend its cash runway and align resources with its development priorities, Nautilus implemented a 16% workforce reduction in early 2025. The company anticipates that its total operating expenses for fiscal year 2025 will be at or below 2024 levels of $81.5 million.
Liquidity
As of December 31, 2024, Nautilus had $206.3 million in cash, cash equivalents, and investments, which it expects will fund operations through 2027. The company's current ratio and quick ratio both stand at 17.40, indicating a strong short-term liquidity position.
Market Opportunity
The global proteomics market is estimated to be approximately $27 billion annually as of 2022 and is expected to grow at an estimated 15% CAGR from 2022 to 2027. This robust market growth underscores the significant opportunity for Nautilus as it works towards commercializing its innovative proteomics platform.
Commercialization Strategy
Nautilus plans to commercialize its platform through a three-phase strategy. The first phase involves research collaborations with biopharmaceutical companies and academic institutions to explore the utility of pre-commercial versions of the platform. The second phase will include an early access limited release program. The third phase is anticipated to consist of a broader commercial launch of the Nautilus platform, including the introduction of the company's proteome analysis system, consumable reagents, and analysis software.
Regarding pricing, Nautilus maintains its previous guidance, expecting an instrument and software bundle to be priced around $1 million, with sample costs starting at a few thousand dollars per sample and declining over time.
