PacBio (NASDAQ: PACB) has appointed Haorui Gene as an official distributor in China to expand access to its HiFi long-read sequencing technology. Haorui Gene, established in 2020, has become a leader in blood typing genomics with seven Sequel II and three Revio systems deployed across China. The company will distribute PacBio's Vega platform throughout China, focusing on transfusion medicine and hematology applications.
Haorui Gene has published over 20 peer-reviewed papers and gained widespread adoption in Chinese blood centers. The company introduced HiFi-based HLA typing products in 2022 and blood group genotyping panels in 2023. In 2024, they expanded collaborations with major blood centers for rare blood classification and erythrocyte antigen mapping research.
PacBio (NASDAQ: PACB) announced the conclusion of an independent investigation by the Special Committee of its Board of Directors regarding allegations from an employee affected by a recent workforce reduction. The investigation focused on employment practices and cybersecurity matters. The Special Committee found that the allegations were unsubstantiated, confirming no improper employment practices and no material inaccuracies in the company's cybersecurity disclosures in its 2024 Form 10-K. Board Chairman John Milligan expressed satisfaction with the investigation's conclusion.
PacBio (PACB) and Chulalongkorn University have announced a strategic collaboration to implement PacBio HiFi whole genome sequencing (WGS) in a newborn screening research program in Thailand. This marks the first initiative in Asia Pacific to use PacBio's HiFi sequencing technology at population scale.
The collaboration aims to evaluate how comprehensive genomic data can support earlier identification of rare and treatable conditions in newborns. PacBio's HiFi WGS technology offers advantages over traditional screening methods by generating highly accurate genomic data, including regions typically inaccessible to short-read methods, while capturing epigenomic information in parallel.
This initiative positions Thailand as a regional leader in population-scale genomics and demonstrates Asia Pacific's growing influence in global genomics. The project aims to establish a scalable research model for genomic newborn screening, potentially serving as a blueprint for other countries seeking to modernize their screening programs.
PacBio (PACB) has announced plans to enhance its methylation detection capabilities in HiFi chemistry through licensing advanced DNA methylation detection methods from The Chinese University of Hong Kong (CUHK). The licensed technology includes the Holistic Kinetic Model 2 (HK2), an AI deep learning framework that will improve the detection of DNA base modifications including 5-hydroxymethylcytosine (5hmC) and hemimethylated 5-methylcytosine (5mC) in native DNA.
The enhanced capabilities will be implemented on PacBio's Revio and Vega systems through software updates, requiring no changes to sequencing protocols or additional costs. The technology enables simultaneous genome and epigenome readout from native DNA without chemical conversion or additional sample preparation. The HK2 model is designed to significantly improve accuracy in 5mC and N6-methyladenine (6mA) detection while introducing native 5hmC calling in single molecules.
PacBio (NASDAQ: PACB) has been selected as a technology partner by the Davos Alzheimer's Collaborative (DAC) for the North African Dementia Registry (NADR) project. The initiative brings together The American University in Cairo and UCL Queen Square Institute of Neurology to create a comprehensive multi-omics dataset focused on Alzheimer's disease and dementia research in North African populations.
The NADR, the first dementia-focused registry of its kind in North Africa, will utilize PacBio's long-read sequencing technology to collect biosamples, conduct cognitive assessments, and perform digital phenotyping. The project aims to address the underrepresentation of North African populations in dementia research, with a particular focus on Egypt's population of over 110 million.
The generated data will be made available through the Alzheimer's Disease Data Initiative (ADDI) platform, providing controlled access to researchers worldwide.
PacBio (NASDAQ: PACB) reported preliminary Q1 2025 revenue of $36.9 million, down from $38.8 million in Q1 2024. The quarter saw mixed results with:
- Instrument revenue declined to $10.8 million (vs $19.0M)
- Record consumable revenue increased to $20.1 million (vs $16.0M)
- Service revenue grew to $6.0 million (vs $3.8M)
The company shipped 12 Revio and 28 Vega systems, with Revio pull-through at ~$236,000. To address market uncertainty, PacBio announced cost-cutting measures to reduce annual operating expenses by $45-50 million. The company maintains its 2025 revenue guidance of $155-170 million and expects non-GAAP gross margin between 35-40%.
PacBio (NASDAQ: PACB) announced the grant of a non-qualified stock option to its new Chief Financial Officer, Jim Gibson. The equity incentive award, approved by the Company's Compensation Committee, includes options for 342,432 shares of PacBio common stock under the 2020 Inducement Plan.
The option has an exercise price of $1.18 per share, matching PacBio's closing price on March 31, 2025. The vesting schedule includes 25% of shares after one year, followed by 1/48th monthly thereafter. The grant, made in accordance with Nasdaq Marketplace Rule 5635(c)(4), serves as an inducement for Gibson's employment and is subject to his continued service through each vesting date.
PacBio (NASDAQ: PACB) has announced the appointment of Jim Gibson as its new Chief Financial Officer, effective March 31, 2025. Gibson brings over 30 years of financial leadership experience from prominent Silicon Valley companies. He joins from Sequoia, where he served as CFO across four entities.

At Willow Innovations, he successfully raised $132 million. PacBio's CEO Christian Henry highlighted Gibson's experience in technology and life sciences as important for the company's next phase, particularly in achieving their goal of positive cash flows by the end of 2027.
PacBio (NASDAQ: PACB) has announced a breakthrough study published in Nature Communications showcasing a new method for analyzing complex genomic regions. The research introduces Paraphase, an informatics tool that, when combined with HiFi long-read sequencing, enables high-precision variant detection in 316 previously inaccessible segmental duplication regions.
The study, led by researchers from PacBio, GeneDx, and a global genomics consortium, successfully analyzed 160 long segmental duplication regions, including 9 medically-relevant genes. Key findings include the discovery of 7 new de novo single nucleotide variants and 4 de novo gene conversion events in 36 trios, as well as comprehensive copy number variability analysis across populations.
The research demonstrates Paraphase's ability to analyze complex gene families like CYP21A2/CYP21A1P, which are associated with conditions such as congenital adrenal hyperplasia, spinal muscular atrophy, and red-green color blindness. The technology overcomes traditional sequencing limitations by phasing haplotypes across paralogous gene families, offering improved accuracy in genetic variation detection.
