PacBio notes that its products and technologies, which include HiFi long-read sequencing, are provided for research use only and are not for use in diagnostic procedures.

The company also references its Revio and Vega systems in financial updates, highlighting these sequencing platforms as contributors to instrument revenue and consumables usage. PacBio reports that its sequencing systems are supported by consumables, including sequencing chemistry and reagents, which contribute to its product revenue alongside instruments and services.

Business model and segment focus

According to the Polygon description and company disclosures, PacBio operates through one reportable segment focused on the development, manufacturing, and marketing of an integrated platform for genetic analysis. Revenue is generated from product sales (instruments and consumables) and service and other revenue. The Polygon description notes that a majority of revenue is derived from the Americas, followed by the Asia-Pacific region and then Europe, the Middle East, and Africa.

PacBio’s press releases describe continued efforts to expand the use of its sequencing technologies in clinical research settings, including rare disease research, carrier screening, and other human health applications. However, the company consistently states that PacBio products are for research use only and not for use in diagnostic procedures.

Applications in human health and rare disease research

PacBio frequently highlights the role of its technologies in rare disease and clinical research. In a news release about a planned collaboration with the n-Lorem Foundation and EspeRare, PacBio describes how long-read whole-genome sequencing can support the development of individualized antisense oligonucleotide (ASO) therapies for ultra-rare genetic diseases. The company notes that ASO therapies require a complete understanding of genomic architecture, including variant phasing, structural variation, repeat expansions, and regulatory alterations that may be missed by standard sequencing approaches.

Under the proposed collaboration, PacBio plans to donate sequencing reagents and provide scientific expertise to support long-read genome analysis for research related to therapeutic treatments for individuals with rare diseases. The company positions long-read whole-genome sequencing as enabling infrastructure for scalable, genomics-driven therapy development in ultra-rare and nano-rare patient populations, while reiterating that its products are for research use.

HiFi sequencing in clinical research studies

PacBio’s news releases describe several large-scale research initiatives using its HiFi sequencing technology. For example, the company reports that a research effort led by UW Medicine and Seattle Children’s will employ PacBio HiFi whole-genome sequencing as a first-line approach to investigate Sudden Unexplained Death in Childhood (SUDC). In that project, trios from families are sequenced on PacBio’s Revio system using SPRQ-Nx chemistry, with the goal of increasing diagnostic yield by resolving complex variants, including structural variants and tandem repeats, and by incorporating parental data to understand inherited and de novo contributors to risk.

PacBio also highlights the HiFi Solves Consortium, a multi-center collaboration evaluating the clinical research utility of HiFi genomes. A study from the HiFi Solves EMEA Consortium, as described by PacBio, showed that HiFi sequencing combined with the Paraphase variant caller identified all known clinically relevant variants in a study cohort across complex genomic regions. PacBio presents this as evidence that high-accuracy long reads can bridge research and potential future clinical utility in genomics.

Technology innovation and methods development

Beyond its core platforms, PacBio participates in the development and dissemination of new sequencing methods that leverage its technologies. In collaboration with researchers at the University of California, Davis, PacBio announced CiFi, a community-developed long-read 3C method that combines chromatin conformation capture with HiFi sequencing. According to the company’s description, CiFi enables chromosome-scale, haplotype-resolved genome assemblies from a single sequencing run, particularly when sample material is limited.

PacBio reports that CiFi delivers multi-contact reads and longer fragments, increasing the information content of proximity ligation experiments. The method is presented as addressing limitations of short-read Hi-C by improving mapping in repetitive regions, enabling multi-contact resolution, and simplifying project workflows through use of a single sequencing platform.

Regulatory milestones and regional partnerships

PacBio also describes its role in supporting regulatory milestones for long-read sequencing. In partnership with Berry Genomics, the company announced that the Sequel II CNDx system received Class III Medical Device Registration approval from the National Medical Products Administration (NMPA) in China. PacBio characterizes this as the first regulatory clearance of a clinical-grade long-read sequencer, enabling clinicians in China to use PacBio HiFi sequencing for conditions such as thalassemia through Berry Genomics’ approved clinical assays and software.

PacBio explains that the Sequel II CNDx system leverages its Single Molecule, Real-Time (SMRT) technology, which the company describes as capable of delivering both high accuracy and long read lengths. In the context of thalassemia and other complex single-gene disorders, PacBio notes that HiFi sequencing can capture single nucleotide variants, insertions and deletions, copy number variants, structural variants, repeat expansions, and enable phasing in a single run.

Financial reporting and investor communications

PacBio provides regular financial updates through press releases and SEC filings. In its third quarter 2025 financial results and preliminary fourth quarter and full-year 2025 revenue announcements, the company reports revenue contributions from instruments, consumables, and service and other revenue. PacBio also discusses metrics such as system placements and consumable revenue, and it comments on initiatives like the introduction of SPRQ-Nx sequencing chemistry and expanded assay portfolios.

The company uses both GAAP and non-GAAP financial measures in its reporting, explaining that non-GAAP metrics are presented for supplemental informational purposes and are reconciled to GAAP measures. In an 8-K filing, PacBio notes that certain earnings-related press releases are furnished rather than filed for purposes of the Securities Exchange Act.
