SEATTLE, July 28, 2026 (GLOBE NEWSWIRE) -- Nautilus Biotechnology, Inc. (NASDAQ:NAUT), a company pioneering a single-molecule proteome analysis platform, today reported financial results for the second quarter ended June 30, 2026.

Second Quarter 2026 Business Highlights

Recognized first revenue in the second quarter of 2026, including grant revenue from the Michael J. Fox Foundation supporting our alpha-synuclein proteoform assay development, together with revenue from our first Iterative Mapping Early Access Program customer.
Grew our commercial organization to three team members, including our previously announced VP of Global Sales, driving engagement with prospective Iterative Mapping Early Access Program customers ahead of the Voyager™ Platform commercial launch.
We have selected and are advancing our first oncology proteoform, AKT1, with expected Early Access availability in late 2026.

Programs & Roadmap Update

In Q1, we launched our Iterative Mapping Early Access program, a services-based program designed to bring Iterative Mapping applications to customers ahead of general availability of consumable kits, with our Tau Proteoforms Assay as the first application made available. Since launch, we have seen strong and growing customer enthusiasm for the proteoform approach and the unique insight it can deliver, including numerous additional customer-requested proteoform targets, representing what we believe to be a significant commercial opportunity. Given the potential scale of this opportunity and the technical performance to date, we are significantly shifting resources across the company and putting a new roadmap in place to accelerate our proteoform applications. Our new realigned roadmap includes:

Voyager™ Platform

Launch expected in early 2027 for pre-orders and anticipated instrument shipment beginning in mid 2027, timed with the Proteoforms Assay consumable kits listed below.

Proteoform Portfolio

Tau Proteoforms Assay: Continued availability through the Iterative Mapping Early Access Program with general availability of consumable kits in mid 2027.
AKT1 Proteoforms Assay: Expected to enter the Iterative Mapping Early Access Program in late 2026, with general availability of consumable kits expected in mid 2027.
Second oncology proteoforms assay with expected general availability of consumable kits in mid 2027.
Third oncology proteoforms assay and continued expansion of our proteoform pipeline with general availability of additional consumable kits in late 2027.
We plan to concurrently develop expanded proteoform portfolio capabilities, such as lower sample input, additional sample types, and increased proteoform depth.

Broadscale Portfolio

In Q2, we completed testing and determined that our assay configuration changes do not sufficiently improve our probe candidate performance to support a 2027 general availability of a broadscale consumable kit at our target specifications.
We have identified key improvement areas and begun the necessary development work required to advance broadscale performance.
We plan to report back on a commercial timeline for the Broadscale Assay at a future date.

"The second quarter reinforced our ever-increasing conviction that proteoforms deliver critical biological resolution that Nautilus is uniquely positioned to deliver," said Sujal Patel, CEO of Nautilus Biotechnology. "Customer enthusiasm for our proteoform applications has been remarkable, and we are prioritizing this market-driven feedback in our updated roadmap. We are funding this shift through reallocation rather than incremental spend, so accelerating our proteoform development does not impact our broader financial assumptions. I believe this realignment puts Nautilus on a more direct and, ultimately, faster path to becoming a commercial company."

Second Quarter 2026 Financial Results

Revenue was $0.2 million for the second quarter of 2026, primarily driven by grant revenue from the commencement of the Company’s activities related to the grant awarded from The Michael J. Fox Foundation during the period, and service revenue for the first sales of services under the Iterative Mapping Early Access Program.

Operating expenses were $15.9 million for the second quarter of 2026, a $1.2 million or 7% decrease compared to $17.1 million for the corresponding prior year period. The decrease in operating expenses is attributable to lower salaries and related benefits, stock-based compensation expense, and facilities costs.

Net loss was $14.5 million for the second quarter of 2026, as compared to the net loss of $15.0 million for the corresponding prior year period.

Cash, cash equivalents, and investments were $129.2 million as of June 30, 2026.

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: the Nautilus Voyager 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.
