• Management shifted the Proteus launch timeline from late 2026 to Q2 2027 to incorporate an additional integrated instrument design cycle aimed at reducing manufacturing risk and improving system repeatability.

• Internal testing of integrated units revealed that moving directly to production would carry unacceptable execution risk; the new cycle focuses on design for manufacturability and first-pass yield improvements.

• The company is pivoting its library preparation strategy from a single generic kit to a suite of application-oriented kits to reduce customer optimization requirements and technical complexity.

• Strategic conviction in the underlying technology remains high, supported by sequencing data generated from current integrated units that met internal performance expectations.

• Management implemented leadership and governance changes to strengthen technical oversight and ensure the Proteus program adheres to strict product readiness gates.

• Platinum placement program insights have identified a significant non-human proteomics market opportunity, estimated at over $4 billion annually, particularly in pathogen and agricultural research.

• Operational expense actions, including a 20% headcount reduction, were initiated to align the cost structure with the extended development timeline while preserving core Proteus work streams.

Guidance Framework and Strategic Outlook

• The revised timeline allows for the delivery of enhanced detection capabilities, with management now targeting 19 or 20 amino acids at launch, up from the previous target of 18.

• Cash runway is now projected to extend into Q4 2028, providing sufficient capital to support the updated Proteus plan and commercial launch execution.

• Full-year 2026 guidance remains unchanged, with revenue expected at approximately $1 million and adjusted operating expenses capped at $98 million.

• Early access programs and customer sample evaluations are now anticipated to begin in late 2026 or early 2027 following the completion of the additional design cycle.

• Management is proactively managing supply chain risks for long-lead components, specifically GPUs, to ensure production is not constrained by broader data center demand.

Structural Changes and Risk Factors

• A targeted reduction in force of approximately 20% of total headcount is expected to generate $12 million in annual operating expense savings.

• The shift to Proteus has resulted in limited near-term capital purchasing for the legacy Platinum system as customers wait for the next-generation platform.

• Management acknowledged that manufacturing integrated machines has been more challenging and time-consuming than originally anticipated, necessitating the roadmap adjustment.

• The company is transitioning away from CMOS-based semiconductor consumables to fused silica arrays for Proteus, reducing exposure to foundry capacity risks.

Internal vs. external drivers for the Proteus roadmap delay

• Management clarified the delay was driven by internal assessments of manufacturing repeatability and yield rather than new customer requirements.

• The additional cycle is intended to ensure that every unit produced meets high performance standards consistently before reaching customers.

Strategic 'hooks' for early Proteus adoption and market entry

• Initial adoption is expected from academic researchers exploring post-translational modifications and biopharma customers focused on non-human proteomics.

• A key advantage is the technology's ability to identify pathogens and toxins without a defined reference, a capability not well-served by existing methods.

Impact of amino acid detection count on market competitiveness

• While the difference between 18 and 20 amino acids is marginal for most applications, reaching 20 is viewed as a psychological milestone for customers accustomed to 'complete' DNA sequencing.

• Launching with 19 or 20 amino acids simplifies the sales cycle by removing the need for customers to justify missing coverage for specific proteins.
