Nautilus Biotechnology, Inc. (NAUT)·Q1 2025 Earnings Summary

Executive Summary

• Q1 2025 was execution-focused with operating expenses down 13% YoY to $18.8M and net loss improving to $16.6M as management continues disciplined cost control and a streamlined structure .
• Cash, cash equivalents, and investments were $192.8M, and management reiterated cash runway through 2027 and late-2026 commercial launch, supported by a ~16% headcount reduction implemented earlier in the year .
• Technically, tau proteoform assay V&V exceeded targets (median percent error ~10%, median CVs ~1.5%–1.7%, within-analyte dynamic range >4 orders of magnitude), strengthening confidence in targeted proteoform and the core platform ahead of broadscale launch .
• Near-term catalysts: the company expects to sign an initial tau-related partnership in the first half of 2025; partnership economics are secondary to demonstrating capability and scientific impact at single-molecule proteoform resolution .
• Consensus estimates for Q1 2025 EPS/revenue were unavailable via S&P Global; comparisons to Street were not possible (see Estimates Context).

What Went Well and What Went Wrong

What Went Well

• Tau proteoform assay V&V results exceeded targets: “median percent error was approximately 10%” vs a ≤30% goal; CVs ~1.5% across lanes and ~1.7% in library prep replicates, “more than 15x better than our targets” .
• Robust assay performance breadth: “within analyte dynamic range exceeding 4 orders of magnitude… several orders of magnitude better than current methods” and compatibility with diverse sample types down to 10μg total protein input with 0.03% tau .
• Cost discipline and runway: OpEx -13% YoY, net loss reduced; management expects FY25 OpEx below FY24 and projects runway through 2027 after ~16% workforce reduction to prioritize development milestones .

What Went Wrong

• Pre-revenue profile persists; management explicitly not prioritizing near-term revenue from partnerships in 2025, focusing instead on scientific validation and platform capability demonstrations .
• Operating losses continue (-$16.6M in Q1), with interest income down YoY reflecting lower investment balances and rates; cash and investments trended down sequentially ($221.2M → $206.3M → $192.8M) .
• External partnering pace (particularly pharma) is slower amid broader market uncertainty; many conversations remain early/exploratory, implying elongated timelines for commercial validation .

Management Commentary

• “The assay’s reproducibility, accuracy, dynamic range, and sample compatibility align closely with our anticipated launch specifications…” .
• “Across all runs, our median percent error was approximately 10%… our observed across lane median CV was 1.5%… median CV across library prep replicates was 1.7%” .
• “During our testing, we observed within analyte dynamic range exceeding 4 orders of magnitude… several orders of magnitude better than current methods” .
• “We continue to expect our total operating expenses for fiscal year 2025 to be below 2024 levels… with our more streamlined cost structure, we continue to project that our cash runway will extend through 2027” .
• “We continue to expect that in the first half of the year, we’ll sign an initial partnership… excitement is universal across customers” .

Q&A Highlights

• Partnership timing and scope: Management expects an initial tau-related partnership in H1 2025, likely starting on the non-profit/academic side; pharma timelines are longer given novelty and pending publications .
• Supply chain/tariffs: No observed sourcing or price impacts; diversified suppliers and low-scale needs mitigate exposure; monitoring continues .
• Partnership economics and revenue focus: Wide range of models (service panels to joint development); 2025 emphasis is on demonstrating capability, not near-term revenue; the company isn’t modeling revenue currently .
• Broadscale assay configuration: Consumables-focused changes progressing; targets include expanding decoding from tens of proteins to full lysates over coming quarters .
• Launch readiness and blind spots: Leadership doesn’t see blind spots; V&V on tau supports confidence in core platform; ongoing customer research indicates strong value proposition and pricing alignment .

Estimates Context

• Street consensus via S&P Global for Q1 2025 EPS and revenue was unavailable for NAUT; estimate comparisons could not be performed using S&P Global data (Primary EPS Consensus Mean, Revenue Consensus Mean returned no values for relevant periods). Values retrieved from S&P Global.*

Key Takeaways for Investors

• Cost trajectory improving: Q1 OpEx down 13% YoY; net loss improved; FY25 OpEx expected below FY24, extending cash runway through 2027 .
• Technical validation strengthens thesis: Tau assay V&V delivered superior accuracy/reproducibility and dynamic range, supporting targeted proteoform and platform credibility pre-launch .
• Near-term catalysts: An initial tau-related partnership announcement in H1 2025 could validate external demand and platform utility; manuscript submission and conference updates are additional events .
• Launch timeline stable: Late-2026 commercial launch reiterated; broadscale assay configuration progressing, reducing technical risk .
• Pre-revenue focus: Management is prioritizing scientific demonstration over revenue in 2025; investor expectations should center on technical milestones and early partnerships rather than financials .
• Cash prudence: Sequential decline in cash/investments ($221.2M → $206.3M → $192.8M) warrants monitoring, but runway through 2027 remains intact after restructuring .
• Risk/monitoring items: Pace of pharma engagement, publication timing, and continued assay maturation; supply chain currently stable despite tariff headlines .
