2022 ANNUAL REPORT

Fellow Stockholders, 

When I joined PacBio in late 2020, I worked with our team to develop a new strategic plan to drive our growth.  
The first phase of that plan, setting the foundation, is primarily comprised of three components: expanding our 
commercial footprint to increase Sequel IIe placements, innovating to create higher throughput sequencing 
platforms, and collaborating to demonstrate the power of HiFi, our long-read sequencing technology. 

I’m pleased to report that despite an extremely challenging macroeconomic environment, we have made 
significant progress on all three strategic core pillars.   

Before we review some of the accomplishments in 2022, I want to recognize the nearly 800 employees of 
PacBio whose efforts are pushing us toward our mission of enabling the power of genomics to improve human 
health. Their focus on innovation and collaborating with our customers has transformed our company. 

Our investment in expanding the commercial organization is driving returns.  In 2022, we grew the Sequel II/IIe 
installed base by 37%.  As a result, we entered 2023 with an installed base of more than 500 units, making 
Sequel II/IIe the most successful sequencer in our history. Importantly, we added approximately 60 brand-new 
instrument customers in the period and had record consumable revenue of $60 million. 

Second, we continued to drive innovation by launching several new products focused on the end-to-end 
sequencing workflow.  This included innovations in our sample preparation methods to lower DNA input 
requirements, developing automation capabilities to enable higher throughput, and delivering new software 
tools that allow our customers to extract more insight from their sequencing results.  These improvements to 
our workflow set the stage for the announcement of the Revio and Onso sequencing platforms.   

In October, we announced two new groundbreaking sequencing instruments, Revio, a long-read sequencer 
with 15-fold higher throughput than the Sequel IIe platform, and Onso, a highly differentiated short-read 
sequencer capable of extraordinary accuracy. 

The Revio platform can sequence more than 1,300 genomes per year at 30x coverage with a consumable cost 
of less than $1,000 per genome.  This dramatic increase in capacity and reduced cost will enable new 
sequencing initiatives.  Our customers responded to the announcement of Revio enthusiastically, ordering 76 
instruments in the fourth quarter alone.  This is by far the strongest response to a new platform in our history.  
This past March, we began shipping the instrument commercially, setting the stage for an exciting 2023.  

Onso is our new short-read sequencer developed for our proprietary Sequencing by Binding (SBB®) 
chemistry, which we acquired from Omniome, Inc. in 2021.  This revolutionary new sequencing chemistry can 
sequence at an extraordinary level of accuracy.  Customer response has been extremely positive in our beta 
program, with one partner reporting accuracy above Q50 levels (1 error in every 100,000 bases!) through the 
entire sequencing run.  We expect to begin commercialization of this platform during the second quarter of 
2023. 

The third part of our strategy was to collaborate with leading institutions around the world to demonstrate the 
power of HiFi sequencing.  Some examples of the progress made during 2022 follow.  In rare disease, new 
research was published in Genomics in Medicine demonstrating that using PacBio HiFi in pediatric rare 
disease research can significantly improve the understanding of the genetic drivers behind these rare 
disorders.  Additionally, during the year, the first human pangenome reference was published with researchers 
using PacBio HiFi sequencing to make significant contributions to this important new reference genome. Also 
in 2022, published in Science, researchers shared the first telomere-to-telomere human genome. These 
landmark insights would likely not have been possible without PacBio HiFi long-read sequencing. 

Looking forward to 2023, our focus will be on accelerating our business.  In particular, in the first half of the 
year, we will focus on continuing the success of the Revio launch.  This includes driving instrument 
placements, scaling manufacturing to support demand, and ensuring each customer has an excellent 
experience with their new Revio system. 

Additionally, in the first half of 2023, we plan to incorporate feedback from our Onso beta partners into the final 
phase of development and prepare for the commercial launch, which we anticipate in late second quarter.  We 
then plan to spend the second half of 2023 demonstrating the utility of SBB chemistry, driving demand, and 
scaling Onso manufacturing.  We also plan to focus our efforts in 2023 on improving our workflows and 
supporting our customers with new informatics tools that leverage the power of HiFi. 

As you can see, we believe 2023 promises to be a transformational year for PacBio! 

In conclusion, on behalf of the Board of Directors and our employees, I’d like to thank our stockholders for their 
support in a challenging yet highly productive 2022.  As a result of this support, we believe we are now the only 
company with leading long and short-read technologies that will enable us to offer our customers highly 
differentiated products and create stockholder value. 

I look forward to updating you on our progress over the course of the year. 

Sincerely,  

Christian Henry

ITEM 1. BUSINESS  

Overview  

We are a premier life science technology company that is designing, developing, and manufacturing advanced sequencing 
solutions that enable scientists and clinical researchers to improve their understanding of the genome and ultimately, resolve 
genetically complex problems.  

Our products and technology under development stem from two highly differentiated core technologies focused on accuracy, 
quality, and completeness, which include our existing HiFi long-read sequencing technology and our emerging Sequencing 
by  Binding  (SBB®)  short-read  sequencing  technology.  Our  products  address  solutions  across  a  broad  set  of  applications 
including human genomics sequencing, plant and animal sciences, infectious disease and microbiology, oncology, and other 
emerging applications. Long-read sequencing was recognized by the journal Nature Methods as its “method of the year” for 
2022 for its contributions to biological understanding and future potential. 

Our  focus  is  on  providing  our  customers  with  advanced  sequencing  technologies  with  higher  throughput  and  improved 
workflows that we believe will enable dramatic advancements in routine healthcare.  

Our  customers  include  academic  and  governmental  research  institutions,  commercial  testing  and  service  laboratories, 
genome  centers,  public  health  labs,  hospitals  and  clinical  research  institutes,  contract  research  organizations  (CROs), 
pharmaceutical companies, and agricultural companies. 

Recent Developments 

On October 25, 2022, we announced two new sequencing platforms, RevioTM and OnsoTM. 

Revio  is  a  new  long-read  sequencing  system  designed  to  enable  the  use  of  HiFi  sequencing  for  large  studies  in  human 
genetics, cancer research, and agricultural genomics. We began taking orders for Revio in the fourth quarter of 2022 and 
expect to commence commercial Revio shipments in March 2023. 

Onso, a short-read DNA sequencing system, is designed to deliver industry-leading sensitivity and specificity for novel insights 
in oncology, disease research, and other applications. We commenced the beta program for Onso in the fourth quarter of 
2022. We began taking orders for Onso during the first quarter of 2023 and remain on track for commercial shipment in the 
second quarter of 2023. 

Our Mission and Impact 

Our mission is to enable the promise of genomics to better human health. Genomics is core to all biological processes, and 
our advanced genomics tools provide scientists and clinical researchers with the insights to better understand biology and 
health.  The  “promise  of  genomics”  postulates  that  medicine,  agriculture,  public  health,  drug  development,  and  other 
disciplines  will  be  fundamentally  transformed  with  the  incorporation  of  routine  genomic  information  over  the  coming 
decades. We see early progress toward this transformation in the applied use of genomics in areas such as genetic disease, 
oncology,  and  sustainable  food  production.  However,  legacy  genomics  technologies  have  fundamental  limitations  in 
progressing  these  fields  toward  the  promise  of  genomics.  We  believe  that  unleashing  the  full  potential  of  genomics  will 
require a level of accuracy and completeness that is inaccessible to legacy technologies. Accuracy and completeness are 
central  to  our  product  development  strategy,  and  thus  we  have  created  some  of  the  most  innovative  and  high-quality 
genomics solutions on the market. Our products also have enhanced multi-omic capabilities to look beyond the genome to 
the transcriptome and epigenome, which we believe is key to deep understanding. 

The Underlying Science 
Genetic  inheritance  in  living  systems  is  conveyed  through  a  naturally  occurring  information  storage  system  known  as 
deoxyribonucleic acid, or DNA. DNA stores information in linear chains of the chemical bases adenine, cytosine, guanine, and 
thymine, represented by the symbols A, C, G, and T respectively. 
In humans, the genome is comprised of approximately three billion DNA base-pairs, which are divided into 23 chromosomes 
ranging in size from 50 million to 250 million bases. A human carries two copies of the chromosomes, one inherited from 
each parent. There are approximately 23,000 smaller regions within these chromosomes, called genes, which contain the 
blueprints  for  protein  production.  The  proteins  synthesized  from  these  blueprints  essentially  underlie  the operation  of  all 
biological systems.  
Genome sequencing reads the bases of long fragments of nucleic acids. Initial genome sequencing studies have shown that 
mutations in these DNA base-pairs play a critical role in human disease, contributing to the burgeoning field of genomics. 
Since  then,  recent  discoveries  have  highlighted  additional  complexities  of  DNA  and  ribonucleic  acid,  or  RNA.  These 
discoveries  include  the  presence  of  chemical  modifications  to  the  bases,  such  as  methylation,  and  post-translational 
modification,  or  the  processing  of  RNA  molecules  after  they  are  transcribed  from  the  genome,  both  of  which  can  affect 
protein synthesis.

Our Principal Markets  

Researchers  utilize  our  solutions  in  human  genomics,  plant  and  animal  sciences,  infectious  disease  and  microbiology, 
oncology, and other emerging applications. 

Human Genomics: Improving rare disease research and understanding 

According to a World Health Organization publication, it is estimated that 400 million people worldwide are affected by up to 
8,000 distinct rare diseases, with 80% of these believed to be genetic in nature. These genetic diseases are DNA differences, 
called variants, in the affected individuals. Variants range in size from single nucleotide substitutions to large losses or gains 
of  entire  chromosomes.  Other  sequencing  technologies  applied  to  rare  disease  diagnosis  are  technologically  limited  to 
interrogating small variants, representing only a subset of possible genomic variation. Consequently, most genetic disease 
cases are undiagnosed, leaving families on multi-year diagnostic odysseys. Sequencing the human genome with long and 
accurate reads enables the potential detection of all known classes of disease-causing variation. In addition, the ability of 
PacBio’s long-read sequencing technology to detect 5-Methylcytosine DNA methylation, an epigenetic modification shown 
to alter gene behavior, may enable further advances in research and development in genetic disease diagnosis.  

Infectious Disease and Microbiology: Understanding and tracking microbes and pathogens in support of global public health 

Our technology has increased the scientific community’s understanding of microorganisms and viruses and their malignancy, 
transmission, and potential resistance to antibiotics or vaccines. Our sequencing technology delivers highly comprehensive 
and complete genomes, enabling federal agencies, public health organizations, and healthcare providers to conduct wide-
ranging research and surveillance activities to: 

•  generate  high  quality,  complete  genome  assemblies,  revealing  variants  of  all  known  types,  to  gain  a  deeper 

understanding of community-acquired and hospital-associated infections and transmissions; 

• 

• 

identify and characterize pathogens to inform regional, national, and global public health agencies for preparation 
and response to rapidly evolving microorganisms; and 

characterize complex microbial communities to understand their role in human, animal, and environmental health. 

Oncology: Enable the discoveries of underlying causes of cancer, progression, and relapse 

Understanding the cellular and molecular complexity of tumor cells is critical in developing more effective targeted cancer 
therapies.  Single-cell  transcriptomics  is  particularly  impactful  in  defining  cellular  identity  and  function;  however,  other 
technologies miss critical information by only sequencing a portion of RNA. Our long-read RNA sequencing method, single-
cell Iso-Seq (scIso-Seq), accurately detects molecular events such as RNA isoforms and expressed mutations and provides 
gene expression information at the single-cell level. We believe scIso-Seq is uniquely positioned to enable discoveries by 
researchers of the underlying causes of cancer initiation, progression, and relapse, as well as the discovery by researchers 
of novel diagnostic, prognostic, and predictive biomarkers that may inform future clinical tests.  

As  novel  discoveries  continue  to  be  made  using  our  long-read  sequencing  technology,  we  believe  our  SBB  short-read 
sequencing technology will enable us to meet the demands of customers in the expanding non-invasive testing market in 
oncology. Due to the small amounts of circulating tumor DNA (ctDNA) present in the blood of early-stage cancer patients 
and those with minimal residual disease (MRD), the presence of cancer often goes undetected, and a more sensitive assay 
will be required. Based on testing internally and at beta customer sites, we believe our SBB technology has the potential to 
offer higher accuracy than competitor sequencing technologies, which may in the future support our customers’ development 
of more sensitive tests for the purpose of earlier detection and more robust monitoring of cancer. 

Plant and Animal Sciences: Helping scientists answer biological questions across a broad range of plant and animal sciences 

There are hundreds of thousands of distinct plant and animal species. Our technology is used to build de novo reference 
genomes for these organisms across several global initiatives which are dedicated to preserving, monitoring, and cataloging 
biodiversity with actionable and accurate genomic data.  

Our Technology, Products, and Solutions 

We have developed HiFi long-read sequencing based on Single-Molecule Real-Time (SMRT) technology, which accurately 
detects the nucleotide sequence and epigenetic status of individual DNA molecules. We are also expanding our genomic 
solutions with our short-read SBB chemistry, which offers sensitive sequencing for short-read applications. Upon launch of 
the SBB platform, we believe we will be the only company offering both native long-read and native short-read technologies 
into the market. 

Our sales consist of sequencing instruments, nanofluidic chips (SMRT Cells), and reagents for preparing DNA and performing 
sequencing based on our SMRT technology; reagents for DNA extraction based on our nanobind technology; and the services 
we perform for customers.

HiFi Long-Read Sequencing 

Our HiFi long-read sequencing protocol was built upon our SMRT sequencing systems, including consumables and software, 
and offers customized end-to-end workflows for different sequencing applications. Highly accurate, long sequence reads 
simplify and accelerate data analysis algorithms, reducing the needs for error correction steps and/or assembly aspects, 
depending on the application. 

Customers use our HiFi long-read sequencing platforms in a wide range of sequencing applications, including whole genome 
sequencing  and  de  novo  genome  assembly,  long-range  phasing,  targeted  sequencing,  full-length  RNA  and  single-cell 
sequencing, characterization of metagenomic communities and other mixed DNA samples, viral genome sequencing, and 
others.  Our  technology  is  also  capable  of  detecting  epigenetic  markers  simultaneously  by  analyzing  the  kinetics  of  DNA 
polymerization that is affected, and thereby detectable, by epigenetic markers such as 5-methylcytosine or N6-methyladenine.  

SMRT Technology 

Our proprietary SMRT Technology enables the observation of DNA synthesis as it occurs in real time by harnessing the natural 
process of DNA replication, which in nature is a highly efficient and accurate process actuated by DNA polymerases. DNA 
polymerases attach to a strand of DNA to be replicated, examine the individual base at the point it is attached, and then 
determine which of the four building blocks, or nucleotides (A, C, G, or T), is required to complement that individual base. 
After determining which nucleotide is required, the polymerases incorporate that nucleotide into the growing strand being 
produced. 

SMRT Sequencing is based on following the activity of DNA polymerase on individual DNA molecules in real time that occurs 
on our SMRT Cells that are monitored and analyzed within our HiFi long-read sequencing systems: the Revio system, Sequel 
II system, Sequel IIe system, and Sequel system. Carried out on SMRTbell® templates, which attach hairpin adapters to the 
ends of double-stranded DNA molecules to be sequenced, SMRT sequencing allows for the successive sequencing of both 
the forward and reverse strands of the individual DNA molecule occurring multiple times, thereby allowing for the same base 
of the same molecule to be sequenced more than once in a sequencing run. The base calls from the serial observation of the 
molecule can be processed to generate the final base call in an analytical procedure called circular consensus sequencing, 
leading to what we have defined as our HiFi sequence reads, which have high accuracy typically being defined as having 
greater than 99% read accuracy, but often exceeding greater than 99.9% accuracy, according to research we performed in 
collaboration with other researchers, subsequently published in Nature Biotechnology in 2019. HiFi reads typically are 15-20 
kilobases in size, depending on the input fragments, providing sufficient read length with our accuracy to support a multitude 
of  applications  across  human  health,  plant  and  animal,  and  microbiology,  according  to  research  we  performed  in 
collaboration with other researchers, subsequently published in Scientific Data in 2020. The ability to generate single-DNA 
molecule sequence reads that are both long and highly accurate allows researchers to obtain more contiguous, complete, 
and accurate genomic data, thereby allowing for greater insights into the complexity of biological systems. 

HiFi Long-Read Sequencing Instruments: Revio system + Sequel systems  

Our Revio, Sequel, Sequel II, and Sequel IIe instruments conduct, monitor, and analyze single-molecule biochemical reactions 
in  real  time.  The  instruments  use  extremely  sensitive  imaging  systems  to  collect  the  light  pulses  emitted  by  fluorescent 
reagents allowing the observation of biological processes. Computer algorithms are used to translate the information that is 
captured by the optics system. Using the recorded information, light pulses are converted into either an A, C, G, or T base call 
with associated quality metrics. Once sequencing is started, the real-time data is delivered to the system’s primary analysis 
pipeline, which outputs base identity and quality values.

HiFi Consumables 

Customers purchase proprietary consumable products to run their PacBio systems, including our SMRT Cells and reagent 
kits. One SMRT Cell is consumed per sequencing reaction, and scientists can choose the number of SMRT Cells they use per 
experiment.  

We offer several reagent kits, each designed to address a specific step in the core sequencing workflow. A library preparation 
kit  is  used  to  convert  DNA  into  SMRTbell  double-stranded  DNA  library  formats  and  includes  typical  molecular  biology 
reagents, such as ligase, buffers, and exonucleases. Our binding kits include our modified DNA polymerase and are used to 
bind SMRTbell libraries to the polymerase in preparation for sequencing. Our core sequencing kits contain reagents required 
for on-instrument, real-time sequencing, including phospholinked nucleotides.  

We have also developed and offer the Multiplexed Arrays Sequencing (MAS-Seq) 3’ kit to enable cost-effective long-read 
single-cell RNA sequencing for a more complete interrogation of the transcriptome. The MAS-Seq kit takes single-cell cDNA 
as an input and outputs a sequencing-ready library, which enables researchers to move beyond gene counting to get full-
length isoform information, characterize the full diversity of transcript isoforms at the single-cell level and ultimately reveal 
cell type-specific spliced isoforms and expressed variants.  

In addition, we offer HiFiViral for SARS-CoV-2, our first fit-for-purpose, end-to-end solution for COVID-19 genome sequencing. 
This solution uses a differentiated molecular inversion probe (MIPs) design that is robust to the emergence of new variants 
in  the  COVID-19  genome  and  allows  for  detection  of  all  known  classes  of  variation  across  the  entire  viral  genome.  Both 
characteristics are required for efficient and effective public health surveillance programs battling the COVID-19 pandemic. 
The  solution  also  includes  fit-for-purpose  software  that  enables  automated  variant  calling  and  preparation  of  files  for 
submission into public databases tracking the evolution of the COVID-19 genome. 

SBB Short-Read Sequencing 

In contrast to SMRT sequencing, SBB reads short fragments of DNA (hundreds of bases instead of kilobases) in a massively 
parallel manner. Current short-read next generation sequencing technologies available in the market incur various rates of 
errors in results. Researchers deploy multiple tactics to try to mitigate these effects, including oversampling or implementing 
complex library preparation methods, yet still face challenges, including missing rare variants. 

We believe our proprietary SBB approach will enable researchers to address the gap in detecting rare variants, especially in 
complex  heterogenous  samples.  Employing  a  two-phase  sequencing  chemistry,  the  SBB  approach  binds  a  dye-labeled 
nucleotide without incorporation into the DNA chain, then removes that base, then blocks and extends with a terminated 
nucleotide. Using nucleotides with single modifications, we incorporate more native bases, avoiding potential scarring due 
to  fluorescent  linker  presence.  This  design  helps  avoid  raw  errors  and  we  believe  can  help  us  develop  a  product  with 
substantially  greater  accuracy  than  currently  marketed  short-read  sequencing  products.  SBB  enables  simplified  upfront 
library  preparation,  redefines  coverage  requirements,  and  reduces  bioinformatic  workload  for  downstream  analysis.  The 
accuracy of our novel sequencing approach has the potential to advance translational cancer research, drive higher fidelity 
single-cell applications, and broadly enable clinical sequencing—even in regions of the genome prone to sequencing errors 
with other short-read sequencing technologies. 

SBB Short-Read Sequencing Instrument: Onso system  

Our  Onso  instrument,  currently  under  development,  conducts,  monitors,  and  analyzes  SBB  biochemical  reactions.  The 
instrument  uses  extremely  sensitive  imaging  systems  to  collect  the  light  emitted  by  fluorescent  reagents  allowing  the 
observation of biological processes. Computer algorithms are used to translate the information that is captured by the optics 
system. Using the recorded information, light pulses are converted into either an A, C, G, or T base call with associated quality 
metrics. Once sequencing is started, the imaging data is delivered to the system’s primary analysis pipeline, which outputs 
base identity and quality values. 

SBB Consumables 

After Onso’s anticipated launch in the second quarter of 2023, our SBB consumable products will be available for purchase, 
including  flow  cells,  clustering,  and  sequencing  reagent  kits.  One  flow  cell  and  associated  sequencing  reagent  pack  is 
consumed  per  sequencing  reaction.  Each  flow  cell  contains  two  lanes  and  scientists  can  choose  to  sequence  different 
samples in each lane while additionally combining any number of flow cells needed per experiment.  

We intend to offer several reagent kits, each designed to address a specific step in the core sequencing workflow. A library 
preparation  kit  is  used  to  convert  DNA  into  SBB  compatible,  double-stranded  DNA  library  formats  and  includes  typical 
molecular biology reagents, such as ligase, buffers, and exonucleases. Additionally for library preparation, our conversion 
kits include reagents to enable scientists to convert existing sequencing libraries into an SBB compatible format. Finally, our 
clustering  and  sequencing  kits  contain  all  reagents  required  for  generating  sequence  ready  clusters  on  flow  cell  and 
performing SBB sequencing reactions on instrument, respectively.

Our Strategy for Growth 

To enable the promise of genomics, our strategy includes the following key elements: 

•  drive rapid adoption of Revio by converting existing Sequel II/IIe customers and attracting new PacBio customers  
•  demonstrate Onso’s extraordinary level of accuracy in the field and show how it can transform research in needle-

in-haystack applications  

•  progress development of ultra-high-throughput and bench top long-read sequencers and next generation SBB short-

read sequencer  

leverage current infrastructure to drive toward positive cash flow  

• 
•  expand partnerships across ecosystem and workflow to drive customer adoption of SBB short-read sequencing 

and HiFi long-read sequencing 

Marketing, Sales, Service, and Support  

We market our products through a global sales force and through distribution partners in Asia and Australia, certain parts of 
Europe, the Middle East and Africa, and Latin America. We plan to continue to invest in growing our marketing, sales, service, 
and support resources as we drive continued adoption of products, launch new products, and expand our customer base. 

Our business is subject to seasonal trends. See the Risk Factors section, specifically the risk factor titled Our operating 
results fluctuate from quarter to quarter and year over year, which makes our future results difficult to predict and could 
negatively impact the market price of our common stock for additional information. 

Customers  

Our  customers  include  academic  and  governmental  research  institutions,  commercial  testing  and  service  laboratories, 
genome  centers,  public  health  labs,  hospitals  and  clinical  research  institutes,  contract  research  organizations  (CROs), 
pharmaceutical companies, and agricultural companies. In general, our customers will isolate, prepare, and analyze genetic 
samples using PacBio sequencing systems in their own laboratories, or they will send their genetic samples to third-party 
service providers who in turn will sequence the samples with PacBio systems and provide the sequence data back to the 
customer for further analysis. For example, customers in academic research institutions may have bacteria, animal, or human 
DNA  samples  isolated  from  various  sources  while  agricultural  biology  companies  may  have  DNA  samples  isolated  from 
different  strains  of  rice,  corn,  or  other  crops.  For  the  years  ended  December  31,  2022,  2021,  and  2020,  one  customer 
accounted for approximately 12%, 13%, and 14% of our total revenue, respectively. 

We believe that the majority of our current customers are early adopters of sequencing technology. By focusing our efforts 
on high-value applications, and developing whole product solutions around these applications, we seek to drive the adoption 
of our products across a broader customer base and into numerous large-scale projects. In general, the broader adoption of 
new technologies by mainstream customers can take a number of years.  

Backlog  

As of December 31, 2022, our instrument backlog was approximately $45.4 million, compared to $2.0 million as of December 
31, 2021. We define backlog as purchase orders or signed contracts from our customers, which we believe are firm and for 
which we have not yet recognized revenue. We expect to convert this backlog to revenue during 2023; however, our ability to 
do so is subject to customers who may seek to cancel or delay their orders even if we are prepared to fulfill them.  

Manufacturing  

We manufacture sequencing instruments, SMRT cells, and reagents. Our key manufacturing and service facility in Menlo 
Park, California has received ISO 13485 and ISO 9001 certifications for the design, development, manufacture, distribution, 
installation, and servicing of its nucleic acid sequencing platforms. We utilize subcontract manufacturers for components of 
the manufacturing process. We purchase both custom and off-the-shelf components from a large number of suppliers and 
subject them to significant quality specifications. We periodically conduct quality audits of most of our critical suppliers and 
have established a supplier certification program. Some of the components required in our products are currently either sole 
sourced or single sourced.

Research and Development  

We have historically made and plan to continue to make significant investments in research and development. Our research 
and development efforts focus on programs to develop new and existing platforms, as well as increasing throughput and 
decreasing costs on behalf of our customers. We are currently developing higher throughput platforms that encompass our 
HiFi  long-read  sequencing.  Our  mid-throughput  short-read  Sequencing  by  Binding  platform,  Onso,  is  currently  under 
development. In addition to platform development, we also innovate across end-to-end workflows to improve usability, as 
well as develop new applications for the advancement of human health.  

Intellectual Property  

Developing and maintaining a strong intellectual property portfolio is an important element of our business. We have sought, 
and  will  continue  to  seek,  patent  protection  for  our  SMRT  and  SBB  technology,  for  improvements  to  our  SMRT  and  SBB 
technology, as well as for any of our other technologies where we believe such protection will be advantageous.  

Our current patent portfolio, including patents exclusively licensed to us, is directed to various technologies, including SMRT 
nucleic acid sequencing and other methods for analyzing biological samples, ZMW arrays, surface treatments, phospholinked 
nucleotides and other reagents for use in nucleic acid sequencing, optical short-read nucleic acid sequencing, nucleic acid 
preparation, and purification components and systems, processes for identifying nucleotides within nucleic acid sequences, 
and processes for analysis and comparison of nucleic acid sequence data. Some of the patents and applications that we 
own, as well as some of the patents and applications that we have licensed from other parties, are subject to U.S. government 
march-in rights, whereby the U.S. government may disregard our exclusive patent rights on its own behalf or on behalf of 
third parties by imposing licenses in certain circumstances, such as if we fail to achieve practical application of the U.S. 
government funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of 
federal regulations, or to give preference to U.S. industry. In addition, U.S. government funded inventions must be reported to 
the government and U.S. government funding must be disclosed in any resulting patent applications.  

As of December 31, 2022, we own or hold exclusive licenses to 406 issued U.S. patents, 100 pending U.S. patent applications, 
396 granted foreign patents, and 158 pending foreign patent applications, including foreign counterparts of U.S. patent and 
patent applications. The full term of the issued U.S. patents will expire between 2023 and 2041. We also have non-exclusive 
patent licenses with various third parties to supplement our own large and robust patent portfolio.  

Of our exclusively licensed patent applications, two issued U.S. patents are licensed to us by the Cornell Research Foundation, 
which manages technology transfers on behalf of Cornell University.  

Other Sequencing Solutions  

There are a significant number of companies offering nucleic acid sequencing equipment or consumables. These include, 
but are not limited to, Illumina, Inc. (“Illumina”), BGI Genomics (also known as MGI or Complete Genomics), Thermo Fisher 
Scientific  Inc.  (“Thermo”),  Oxford  Nanopore  Technologies  Ltd.  (“ONT  Ltd.”),  Roche  Holding  AG  (“Roche”),  Qiagen  N.V. 
(“Qiagen”), Element Biosciences, Inc. (“Element”), Bionano Genomics, Inc. (“Bionano”), Ultima Genomics, Inc. (“Ultima”) and 
Singular  Genomics  Systems,  Inc.  (“Singular”).  These  companies  may  have  different  levels  of  financial,  technical, 
manufacturing, administrative, and support resources available to them. We expect the competition to intensify within the 
overall  nucleic  acid  sequencing  market  as  there  are  also  several  companies  developing  new  sequencing  technologies, 
products and/or services. Increased competition may result in pricing pressures, which could harm our sales, profitability, or 
share of supply. 

In order for us to maintain and increase our sales, we will need to demonstrate that our products deliver superior performance 
and  value  as  a  result  of  our  key  differentiators.  Our  HiFi  long-read  sequencing  will  need  to  continue  to  deliver  very  high 
consensus accuracy and long-read lengths and include single-molecule, real-time resolution, with the ability to detect real-
time kinetic information, fast time to result and flexibility, as well as support the breadth and depth of current and future 
applications.  

Government Regulation 

The  development,  testing,  manufacturing,  marketing,  post-market  surveillance,  distribution,  advertising,  and  labeling  of 
certain medical devices, including in vitro diagnostic products and laboratory-developed tests, are subject to regulation in the 
United States by the Center for Devices and Radiological Health of the U.S. Food and Drug Administration (FDA) under the 
Federal Food, Drug, and Cosmetic Act (FDCA) and comparable state and foreign regulatory agencies. FDA defines a medical 
device as an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent, or other similar or related 
article,  including  any  component  part  or  accessory,  which  is  (i)  intended  for  use  in  the  diagnosis  of  disease  or  other 
conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals, or (ii) intended to affect 
the structure or any function of the body of man or other animals and which does not achieve any of its primary intended 
purposes through chemical action within or on the body of man or other animals and which is not dependent upon being 

7 

 
metabolized for the achievement of any of its primary intended purposes. Medical devices to be commercially distributed in 
the United States must receive from the FDA either clearance of a pre-market notification, known as 510(k), or pre-market 
approval pursuant to the FDC Act prior to marketing, unless subject to an exemption. 

We intend to label and sell our products for research use only (“RUO”) and expect to sell them to research customers in 
various  settings,  including  academic  institutions,  life  sciences  and  research  laboratories  that  conduct  research,  and 
biopharmaceutical and biotechnology companies for non-diagnostic and non-clinical purposes. Our current RUO products 
are not intended or promoted for use in clinical practice in the diagnosis of disease or other conditions, and they are labeled 
for research use only, not for use in diagnostic procedures. Accordingly, we believe our products, as we intend to market 
them, are not subject to regulation by the FDA. Rather, while FDA regulations require that RUO products be labeled for research 
use only and to market and distribute RUO products in accordance with the FDA RUO guidance, the regulations do not subject 
RUO products to the FDA’s jurisdiction or the broader pre- and post-market controls for medical devices. However, in the 
future, certain of our products or related applications, such as those that may be developed for clinical uses, could be subject 
to FDA regulation, or the FDA’s regulatory jurisdiction could be expanded to include our products. If we wish to label and 
expand product lines to address the diagnosis of disease, regulation by governmental authorities in the United States and 
other  countries  will  become  an  increasingly  significant  factor  in  development,  testing,  production,  and  marketing.  In  the 
future, products that we may develop in the molecular diagnostic markets, depending on their intended use, may be regulated 
as medical devices or in vitro diagnostic products (“IVDs”) by the FDA and comparable agencies in other countries. In the 
U.S., if we market our products for use in performing clinical diagnostics, such products would be subject to regulation by 
the  FDA  under  pre-market  and  post-market  control  as  medical  devices,  unless  an  exemption  applies,  and  we  would  be 
required to obtain either prior 510(k) clearance or prior pre-market approval from the FDA before commercializing the product. 
Obtaining  the  requisite  regulatory  approvals  can  be  expensive  and  may  involve considerable delay.  Some  countries  have 
regulatory review processes that are substantially longer than U.S. processes. Failure to obtain regulatory approval in a timely 
manner and meet all of the local regulatory requirements including language and specific safety standards in any foreign 
country in which we plan to market our products could prevent us from marketing products in such countries or subject us 
to  sanctions  and  fines.  Changes  to  the  current  regulatory  framework,  including  the  imposition  of  additional  or  new 
regulations, could arise at any time during the development or marketing of our products.  

In November 2013, the FDA issued a final guidance on products labeled for research use only, which, among other things, 
reaffirmed that a company may not make any clinical or diagnostic claims about an RUO product, stating that merely including 
a labeling statement that the product is for research purposes only will not necessarily render the device exempt from the 
FDA’s clearance, approval, or other regulatory requirements if the totality of circumstances surrounding the distribution of 
the  product  indicates  that  the  manufacturer  knows  its  product  is  being  used  by  customers  for  diagnostic  uses  or  the 
manufacturer intends such a use. These circumstances may include, among other things, written or verbal marketing claims 
regarding a product’s performance in clinical diagnostic applications and a manufacturer’s provision of technical support for 
such activities. If FDA were to determine, based on the totality of circumstances, that our products labeled and marketed for 
RUO are intended for diagnostic purposes, they would be considered medical devices that will require clearance or approval 
prior  to  commercialization.  Further,  sales  of  devices  for  diagnostic  purposes  may  subject  us  to  additional  healthcare 
regulation. We continue to monitor the changing legal and regulatory landscape to ensure our compliance with any applicable 
rules, laws and regulations.  

The FDA classifies medical devices into one of three classes. Devices deemed to pose lower risk to the patient are placed in 
either  class  I  or  II,  which,  unless  an  exemption  applies,  requires  the  manufacturer  to  submit  a  pre-market  notification 
requesting FDA clearance for commercial distribution pursuant to Section 510(k) of the FDCA. This process, known as 510(k) 
clearance, requires that the manufacturer demonstrate that the device is substantially equivalent to a previously cleared and 
legally marketed 510(k) device or a “pre-amendment” class III device for which pre-market approval applications (“PMAs”) 
have not been required by the FDA. This FDA review process typically takes from four to twelve months, although it can take 
longer.  Most  Class  I  devices  are  exempted  from  this  510(k)  pre-market  submission  requirement.  If  no  legally  marketed 
predicate can be identified for a new device to enable the use of the 510(k) pathway, the device is automatically classified 
under the FDCA as Class III, which generally requires pre-market approval, or PMA approval. However, the FDA can reclassify 
or use “de novo classification” for a device that meets the FDCA standards for a Class II device, permitting the device to be 
marketed  without  PMA  approval.  To  grant  such  a  reclassification,  FDA  must  determine  that  the  FDCA’s  general  controls 
alone,  or  general  controls and  special  controls together,  are  sufficient to  provide  a  reasonable  assurance  of  the  device’s 
safety and effectiveness. The de novo classification route is generally less burdensome than the PMA approval process. 

Devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life-supporting, or implantable devices, or those 
deemed not substantially equivalent to a legally marketed predicate device, are placed in class III. Class III devices typically 
require PMA approval. To obtain PMA approval, an applicant must demonstrate the reasonable safety and effectiveness of 
the  device  based,  in  part,  on  data  obtained  in  clinical  studies.  All  clinical  studies  of  investigational  medical  devices  to 
determine safety and effectiveness must be conducted in accordance with FDA’s investigational device exemption (“IDE”) 
regulations, including the requirement for the study sponsor to submit an IDE application to FDA, unless exempt, which must 
become  effective  prior  to  commencing  human  clinical  studies.  PMA  reviews  generally  last  between  one  and  two  years, 

8 

 
although they can take longer. Both the 510(k) and the PMA processes can be expensive and lengthy and may not result in 
clearance or approval. If we are required to submit our products for pre-market review by the FDA, we may be required to 
delay marketing and commercialization while we obtain pre-market clearance or approval from the FDA. There would be no 
assurance that we could ever obtain such clearance or approval. 

All medical devices, including IVDs, that are regulated by the FDA are also subject to the quality system regulation. Obtaining 
the requisite regulatory approvals, including the FDA quality system inspections that are required for PMA approval, can be 
expensive  and  may  involve  considerable  delay.  The  regulatory  approval  process  for  such  products  may  be  significantly 
delayed, may be significantly more expensive than anticipated, and may conclude without such products being approved by 
the FDA. Without timely regulatory approval, we will not be able to launch or successfully commercialize such diagnostic 
products. Changes to the current regulatory framework, including the imposition of additional or new regulations, could arise 
at any time during the development or marketing of our products. This may negatively affect our ability to obtain or maintain 
FDA  or  comparable  regulatory  clearance  or  approval  of  our  products  in  the  future.  In  addition,  regulatory  agencies  may 
introduce new requirements that may change the regulatory requirements for us or our customers, or both. 

As noted above, although our products are currently labeled and sold for research purposes only, the regulatory requirements 
related to marketing, selling, and supporting such products could be uncertain and depend on the totality of circumstances. 
This  uncertainty  exists  even  if  such  use  by  our  customers  occurs  without  our  consent.  If  the  FDA  or  other  regulatory 
authorities  assert  that  any  of  our  RUO  products  are  subject  to  regulatory  clearance  or  approval,  our  business,  financial 
condition, or results of operations could be adversely affected. 

For example, in some cases, our customers, including laboratories that offer services as part of our certified service provider 
program, may use our RUO products in their own laboratory-developed tests (“LDTs”) or in other FDA-regulated products for 
clinical  diagnostic  use.  The  FDA  has  historically  exercised  enforcement  discretion  in  not  enforcing  the  medical  device 
regulations  against  LDTs  and  LDT  manufacturers.  However,  on  October  3,  2014,  the  FDA  issued  two  draft  guidance 
documents that set forth the FDA’s proposed risk-based framework for regulating LDTs, which are designed, manufactured, 
and  used  within  a  single  laboratory.  In  January  2017,  the  FDA  announced  that  it  would  not  issue  final  guidance  on  the 
oversight of LDTs and LDT manufacturers but would seek further public discussion on an appropriate oversight approach 
and give Congress an opportunity to develop a legislative solution. The FDA has issued warning letters to genomics labs for 
illegally marketing genetic tests that claim to predict patients’ responses to specific medications, noting that the FDA has 
not created a legal “carve-out” for LDTs and retains discretion to take action when appropriate, such as when certain genomic 
tests raise significant public health concerns. As laboratories and manufacturers develop more complex genetic tests and 
diagnostic software, the FDA may increase its regulation of LDTs. Legislative and administrative proposals to amend the 
FDA's  oversight  of  LDTs  have  been  introduced  in  recent  years,  including  the  Verifying  Accurate  Leading-edge  IVCT 
Development Act of 2021 (the “VALID Act”). In September 2022, Congress passed the FDA user fee reauthorization legislation 
without substantive FDA policy riders, including the VALID Act, but Congress may revisit the policy riders and enact other FDA 
programmatic  reforms  in  the  future.  Any  future  legislative  or  administrative  rule  making  or  oversight  of  LDTs  and  LDT 
manufacturers, if and when finalized, may impact the sales of our products and how customers use our products, and may 
require us to change our business model in order to maintain compliance with these laws. We would become subject to 
additional FDA requirements if our products are determined to be medical devices or if we elect to seek 510(k) clearance or 
pre-market  approval.  If  our  products  become  subject  to  FDA  regulation  as  medical  devices,  we  would  need  to  invest 
significant time and resources to ensure ongoing compliance with FDA quality system regulations and other post-market 
regulatory requirements. 

If  our  products  become  subject  to  FDA  regulation  as  medical  devices,  the  regulatory  clearance  or  approval  and  the 
maintenance of continued and post-market regulatory compliance for such products will be expensive, time-consuming, and 
uncertain both in timing and in outcome. Commercialization of such regulated medical devices can increase our exposure 
under  additional  laws.  For  example,  medical  device  companies  are  subject  to  additional  healthcare  regulation  and 
enforcement by the federal government and by authorities in the states and foreign jurisdictions in which they conduct their 
business and may constrain the financial arrangements and relationships through which we research, as well as sell, market 
and distribute any medical products for which we obtain marketing authorization. Such laws include, without limitation, state 
and federal anti-kickback, fraud and abuse, false claims, data privacy and security, and transparency laws and regulations 
related to payments and other transfers of value made to physicians and other healthcare providers. If our operations are 
found to be in violation of any of such laws or any other governmental regulations that apply, we may be subject to penalties, 
including, without limitation, administrative, civil, and criminal penalties, damages, fines, disgorgement, the curtailment or 
restructuring of operations, integrity oversight and reporting obligations, exclusion from participation in federal and state 
healthcare programs and imprisonment.  

In the future, to the extent we develop any clinical diagnostic assays, we may pursue payment for such products through a 
diverse and broad range of channels and seek coverage and reimbursement by government health insurance programs and 
commercial third-party payors for such products. In the United States, there is no uniform coverage for clinical laboratory 
tests. The extent of coverage and rate of payment for covered services or items vary from payor to payor. Obtaining coverage 

9 

 
and reimbursement for such products can be uncertain, time-consuming, and expensive, and, even if favorable coverage and 
reimbursement  status  were  attained  for  our  tests,  to  the  extent  applicable,  less  favorable  coverage  policies  and 
reimbursement rates may be implemented in the future. Changes in healthcare regulatory policies could also increase our 
costs and subject us to additional regulatory requirements that may interrupt commercialization of our products, decrease 
our revenue and adversely impact sales of, and pricing of and reimbursement for, our products. 

International sales of medical devices are subject to foreign government regulations, which vary substantially from country 
to country. In the future, if we decide to distribute or market our diagnostic products as IVDs in Europe, such products are 
subject to regulation under the European Union (“EU”) IVD Medical Device Regulation (“IVDR”) EU 2017/746. Outside of the 
EU, regulatory approval needs to be sought on a country-by-country basis in order to market medical devices. Although there 
is a trend towards harmonization of a quality system, standards and regulations in each country may vary substantially, which 
can affect timelines of introduction. 

We are committed to the protection of our employees and the environment. Our operations require the use of hazardous 
materials that subject us to various federal, state, and local environmental and safety laws and regulations. We believe that 
we are in material compliance with current applicable laws and regulations. However, we could be held liable for damages 
and fines should contamination of the environment or individual exposures to hazardous substances occur. In addition, we 
cannot predict how changes in these laws and regulations, or the development of new laws and regulations, will affect our 
business operations or the cost of compliance. 

Additionally, we must comply with complex foreign and U.S. laws and regulations, such as the U.S. Foreign Corrupt Practices 
Act,  the  U.K.  Bribery  Act,  and  other  local  laws  prohibiting  corrupt  payments  to  governmental  officials,  anti-competition 
regulations  and  sanctions  imposed  by  the  U.S.  Office  of  Foreign  Assets  Control,  and  other  similar  laws  and  regulations. 
Violations of these laws and regulations could result in fines and penalties, criminal sanctions, restrictions on our business 
conduct, and on our ability to offer our products in one or more countries, and could also materially affect our brand, our 
ability to attract and retain employees, our international operations, our business, and our operating results. Although we 
have implemented policies and procedures designed to ensure compliance with these laws and regulations, there can be no 
assurance that our employees, contractors, or agents will not violate our policies. 

As we continue to expand our business into multiple international markets, our success will depend, in large part, on our 
ability to anticipate and effectively manage these and other risks associated with our international operations. Any of these 
risks could harm our international operations and negatively impact our sales, adversely affecting our business, results of 
operations, financial condition, and growth prospects. 

Human Capital  

As of December 31, 2022, we had 769 full-time employees. Of these employees, 352 were in research and development, 64 
were in operations, 36 were in service, 204 were in marketing, sales, and customer support, and 113 were in general and 
administration. With the exception of our field-based sales, marketing, and service teams, the majority of our employees are 
in California. None of our employees are represented by labor unions or are covered by a collective bargaining agreement 
with respect to their employment. We have not experienced any work stoppages, and we consider our relationship with our 
employees to be good.  

Talent Acquisition and Retention 

We recognize that our employees largely contribute to our success. To this end, we support business growth by seeking to 
attract and retain best-in-class talent. Our talent acquisition team uses internal and external resources to recruit highly skilled 
candidates globally.  

Total Rewards 

Our total rewards philosophy has been to invest in our workforce by offering competitive and fair compensation and benefits 
packages. We provide employees with compensation packages that include base salary, short-term incentives such as annual 
bonuses and commissions, and long-term equity awards. We also offer comprehensive employee benefits, which vary by 
country and region, such as life, disability, and health insurance, health savings and flexible spending accounts, paid time off, 
paid parental leave, Employee Stock Purchase Program, and a 401(k) plan. It is our expressed intent to be an employer of 
choice in our industry by providing market-competitive compensation and benefits packages. 

Health, Safety, and Wellness 

The health, safety, and wellness of our employees is a priority in which we have always invested and will continue to do so. 
We  provide  our  employees  and  their  families  with  access  to  a  variety  of  innovative,  flexible,  and  convenient  health  and 
wellness programs. Program benefits are intended to provide protection and security, so employees can have peace of mind 
concerning events that may require time away from work or that may impact their financial well-being. These programs are 
highlighted regularly in our monthly human resources newsletters.

We  continue  our  investments  in,  and  the  prioritization  of,  employee  health,  safety,  and  wellness  in  light  of  the  COVID-19 
pandemic.  To  protect  and  support  our  essential  team  members,  we  have  implemented  health  and  safety  measures  that 
included  a  mandatory  vaccination  policy  for  our  U.S.-based  employees,  maximizing  personal  workspaces,  changing  shift 
schedules, and providing personal protective equipment (PPE). We have also supported access to testing by holding on-site 
testing  clinics  available  to  employees  and  their  family  members.  We  continue  to  monitor  this  evolving  situation  and  will 
continue to seek programs to educate and assist employees whenever possible.  

Diversity, Equity, and Inclusion 

We believe a diverse workforce is critical to our success. Our mission is to value differences in races, ethnicities, religions, 
nationalities, genders, ages, sexual orientations, as well as education, skill sets and experience. We offer training programs 
on  diversity  awareness  to  help  employees  understand,  recognize,  respond,  and  prevent  bias  throughout  the  employee 
lifecycle.  We are focused on inclusive hiring practices, fair and equitable treatment, organizational flexibility, and training and 
resources. 

Training and Development 

We believe in encouraging employees to becoming lifelong learners by providing ongoing learning and leadership training 
opportunities. We provide a scaled learning platform of on-demand and virtual classroom learning focused on personal and 
professional  development.  While  we  strive  to  provide  real-time  recognition  of  employee  performance,  we  have  a  formal 
annual review process not only to determine pay and equity adjustments tied to individual contributions, but to identify areas 
where training and development may be needed.

Risks Related to Our Business 

The commercialization and sales of our current or future products may be unsuccessful or less successful than anticipated. 
While we plan to continue pursuing new products and expand into adjacent markets, we have limited experience in managing 
and selling multiple products and, as a result, may face challenges selling in new markets and fail to successfully carry out 
these initiatives, which may adversely impact our business, financial condition or results of operation. 

We have made and expect to continue making substantial investments to develop new products and enhance our existing 
products  through  our  acquisitions  and  research  and  development  efforts.  For  example,  we  recently  announced our  new 
RevioTM long-read sequencing system in the fourth quarter of 2022, and expect to commence commercial Revio shipments 
in March 2023, and we are also progressing development of OnsoTM, our SBB short-read platform, and remain on track for 
commercial  shipment  in  the  second  quarter  of  2023.  Our  future  success  is  substantially  dependent  on  our  ability  to 
successfully  develop  and  commercialize  our  products,  including  Revio  and  Onso,  which  are  anticipated  to  be  used  in 
demanding  scientific  research  that  requires  substantial  levels  of  accuracy  and  precision.  In  addition,  we  may  not  be 
successful in transitioning our Revio and Onso products from our prior generation products, and could incur related obsolete 
inventory charges. Customers may also be slower that we anticipate in making new capital equipment acquisitions, especially 
in  the  current  economic  environment.  However,  due  to  challenges  we  may  experience  in  developing  and  marketing  our 
existing products and launching new products, we may not be able to effectively: 

•  manage  the  timeliness  of  our  new  product  introductions  and  the  rate  at  which  sales  of  our  new  products  may 

• 

cannibalize sales of our older products or manage sales and marketing of multiple sequencing platforms; 
drive adoption of our current and future products, including the Sequel II/IIe Systems, the Revio system and products 
under development related to our emerging SBB technology, including the Onso system; 

•  maintain our competitive position by continuing to attract and retain customers for our products; 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

provide appropriate levels of customer training and support for our products; 

implement an effective marketing strategy to promote awareness of our products; 

develop and implement an effective sales and distribution strategy for our current and future products; 

develop, manufacture and commercialize new products or achieve an acceptable return on our manufacturing or 
research and development efforts and expenses; 
comply with regulatory requirements applicable to our products; 

anticipate and adapt to changes in our market; 

accommodate customer expectations and demands with respect to our products, increase product adoption by our 
existing customers or develop new customer relationships; 
deliver  our  beta  systems  to  our  external  beta  testing  sites  or  complete  our  external  beta  testing  program  on  our 
currently expected timelines; 
overcome unexpected challenges discovered during beta testing; 

complete the scientific and technical validation of new products, such as Onso, on our currently expected timeline or 
at all; 
deliver our future products in a timely manner to our customers; 

grow our share by marketing and selling our products for new and additional applications; 

•  manage the significant burdens that expanding our existing or future products into current and new markets may 

impose on marketing, compliance, and other administrative and managerial resources; 

•  maintain  and  develop  strategic  relationships  with  vendors,  manufacturers,  and  other industry  partners  to  acquire 
necessary materials for the production of, and to develop, manufacture and commercialize, our existing or future 
products; 
adapt  or  scale  our  manufacturing  activities  to  meet  performance  specifications  and  potential  demand  at  a 
reasonable cost; 
avoid infringement and misappropriation of third-party intellectual property; 

• 

• 

• 

• 

• 

• 

obtain and maintain any necessary licenses to third-party intellectual property on commercially reasonable terms; 

obtain valid and enforceable patents that give us a competitive advantage or enforce existing patents; 

protect our proprietary technology; and 

attract, retain, and motivate qualified personnel.

The  risks  noted  above,  especially  with  respect  to  the  marketing,  sales,  and  commercialization  of  our  products,  may  be 
heightened by the impact of current uncertain market and other conditions. In addition, a high percentage of our expenses is 
and will continue to be fixed. Accordingly, if we do not generate revenue as and when anticipated, we could suffer a material 
adverse effect on our business, financial conditions, results of operations and prospects. 

We have incurred losses to date, and we expect to continue to incur significant losses as we develop our business and may 
never achieve profitability. 

We have generally incurred net losses each quarter since inception, and we cannot be certain if or when we will produce 
sufficient revenue from our operations to support our costs. Even if profitability is achieved in the future, we may not be able 
to sustain profitability on a consistent basis. We expect to continue to incur substantial losses and negative cash flow from 
operations for the foreseeable future. 

Our net losses since inception and our expectation of incurring substantial losses and negative cash flow for the foreseeable 
future could: 

•  make it more difficult for us to satisfy our obligations; 

• 

• 

• 

• 

• 

• 

increase our vulnerability to general adverse economic and industry conditions; 

limit our ability to fund future working capital, capital expenditures, research and development and other business opportun

increase the volatility of the price of our common stock; 

limit our flexibility to react to changes in our business and the industry in which we operate; 

place us at a disadvantage to other companies that offer nucleic acid sequencing equipment or consumables; and 

limit our ability to borrow additional funds. 

In addition, inflationary pressure, including as a result of supply shortages, has adversely impacted and could continue to 
adversely impact our financial results, and our operating costs may increase. We may not fully offset these cost increases 
by  raising  prices  for  our  products  and  services,  which  could  result  in  downward  pressure  on  our  margins.  Further,  our 
customers may choose to reduce their business with us if we increase our pricing. 

Any or all of the foregoing may have a material adverse effect on our business, operations, financial condition, and prospects. 
An impairment in value of our tangible or intangible assets could also be recorded as a result of weaker economic conditions. 

We are not cash flow positive and may not have sufficient cash to make required payments under the terms of our debt or fund 
our long-term planned operations. 

Our operations have consumed substantial amounts of cash since inception, and we expect to continue to incur substantial 
losses and negative cash flow from operations for the foreseeable future. Additional funds may not be available on terms 
acceptable to us or at all. We have incurred and may further incur additional debt, including the debt incurred through issuance 
of $900.0 million in aggregate principal amount of 1.50% Convertible Senior Notes due 2028. We may not have sufficient 
cash  to  make  required  payments  under  the  terms  of  this  debt,  and  should  this  occur,  debt  holders  have  rights  senior  to 
common stockholders to make claims on our assets. We may not be able to issue equity securities due to unacceptable 
terms and conditions to us in the capital markets. To the extent that we intend to raise additional funds through the sale of 
our common stock, downward fluctuations in our stock price could adversely affect such fundraising efforts. Furthermore, 
equity financings normally involve shares sold at a discount to the current market price and fundraising through sales of 
additional shares of common stock or other equity securities will have a dilutive effect on our existing investors. The shares 
may also be sold at a time when the market price for our common stock is low because we are in need of the funds, which 
will further dilute existing holders more than if the market price for our common stock was higher. 

We believe that our growth will depend, in part, on our ability to fund our commercialization efforts and our efforts to develop 
new products, including any improvements to our existing products and the continued development and anticipated launch 
of  the  Revio HiFi  long-read  system  and  the  Onso SBB  short-read  system.  To  the  extent  our  existing  resources  are  not 
sufficient, it may require us to delay, or even not allow us to conduct any or all of these activities that we believe would be 
beneficial for our future growth. We may need to raise additional funds through public or private debt or equity financing or 
alternative financing arrangements, which may include collaborations or licensing arrangements. If we are unable to raise 
funds  on  favorable  terms,  or  at  all,  we  may  have  to  reduce  our  cash  burn  rate  and  may  not  be  able  to  support  our 
commercialization efforts, launching of new products, or operations, or to increase or maintain the level of our research and 
development activities. 

If we are unable to generate sufficient cash flows or to raise adequate funds to finance our forecasted expenditures, we may 
have to make significant changes to our operations, including delaying or reducing the scope of, or eliminating some or all 
of,  our  development  programs.  We  also  may  have  to  reduce  sales,  marketing,  engineering,  customer  support  or  other 
resources devoted to our existing or new products, or we may need to cease operations. Any of these actions could materially 

14 

 
 
 
 
  
  
  
 
  
  
  
  
impede  our  ability  to  achieve  our  business  objectives  and  could  materially  harm  our  operating  results. If  our  cash,  cash 
equivalents and investments are insufficient to fund our projected operating requirements and we are unable to raise capital, 
it could have a material adverse effect on our business, financial condition and results of operations and prospects. 

We have made acquisitions and, in the future, may continue to acquire businesses, technologies or assets, form joint ventures 
or make other strategic investments with companies that could adversely affect our operating results, dilute our stockholders’ 
ownership, or cause us to incur debt or significant expense. 

As  part  of  our  business  strategy,  we  have  acquired  and  expect  to  continue  to  pursue  acquisitions  of  complementary 
businesses,  technologies,  or  assets.  We  may  also  pursue  technology  license  arrangements,  strategic  alliances  or 
investments  that  complement  our  business.  In  July 2021,  we  acquired  Circulomics,  and  in  September 2021,  we  acquired 
Omniome. As of December 31, 2022, we recorded goodwill of $410.0 million and intangible assets of $410.2 million. See 
Note 2. Business Acquisitions, in Part II, Item 8 of this Annual Report on Form 10-K. 

Acquisitions and strategic transactions involve numerous risks, any of which could harm our business and negatively affect 
our financial condition and results of operations, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

intense competition for suitable acquisition targets, which could increase prices and adversely affect our ability to 
consummate deals on favorable or acceptable terms; 

failure or material delay in closing a transaction; 

transaction-related lawsuits or claims; 

difficulties in integrating the technologies, operations, existing contracts, and personnel of an acquired company; 

difficulties in retaining key employees or business partners of an acquired company; 

difficulties in retaining suppliers, partners, or customers of an acquired company; 

challenges with integrating the brand identity of an acquired company with our own; 

diversion of financial and management resources from existing operations or alternative acquisition opportunities; 

failure to realize the anticipated benefits or synergies of a transaction; 

difficulties in developing technology post-acquisition; 

failure to identify the problems, liabilities, or other shortcomings or challenges of an acquired company or technology, 
including issues related to intellectual property, regulatory compliance practices, litigation, revenue recognition or 
other accounting practices, or employee or user issues; 

risks  that  regulatory  bodies  may  enact  new  laws  or  promulgate  new  regulations  that  are  adverse  to  an  acquired 
company or business; 

risks that regulatory bodies do not approve our acquisitions or business combinations or delay such approvals; 

theft of our trade secrets or confidential information that we share with potential acquisition candidates or other 
potential strategic partners; 

risk that an acquired company or investment in new services cannibalizes a portion of our existing business; and 

adverse market reaction to an acquisition or other strategic transaction. 

To finance any acquisitions or other strategic investments, we may raise additional funds, which could adversely affect our 
existing stockholders and our business. If the price of our common stock is low or volatile, we may not be able to acquire 
other  companies  for  stock.  In  addition,  our  stockholders  may  experience  substantial  dilution  as  a  result  of  additional 
securities  we  may  issue  for  acquisitions.  Open  market  sales  of  substantial  amounts  of  our  common  stock  issued  to 
stockholders of companies we acquire could also depress our stock price. Additional funds may not be available on terms 
that are favorable to us, or at all. 

If  we  fail to  address the  foregoing risks  or  other  problems  encountered in  connection with past  or  future  acquisitions  of 
businesses, new technologies, services, and other assets and strategic investments, or if we fail to successfully integrate 
such acquisitions or investments, our business, financial condition, and results of operations could be adversely affected, 
including potential impairments of goodwill and intangible assets.

If we are unable to successfully develop and timely manufacture our current and future products, including with respect to 
SMRT Cells, Sequel II/IIe Systems, Revio, Onso, and other SMRT Cell, HiFi, and SBB products under development, and related 
products, our business may be adversely affected. 

In  light  of  the  highly  complex  technologies  involved  in  our  products,  there  can  be  no  assurance  that  we  will  be  able  to 
manufacture and commercialize our current and future products on a timely basis or continue providing adequate support 
for our existing products. The commercial success of our products, including the Sequel and Sequel II/IIe Systems, and the 
Revio and Onso products under development, depends on a number of factors, including performance and reliability of the 
systems,  our  anticipating  and  effectively  addressing  customer  preferences  and  demands,  the  success  of  our  sales  and 
marketing efforts, effective forecasting and management of product demand, purchase commitments and inventory levels, 
effective management of manufacturing and supply costs, and the quality of our products, including consumables such as 
SMRT  Cells  and  reagents.  Should  we  face  delays  in  or  discover  unexpected  defects  during  the  further  development  or 
manufacturing  process  of  instruments  or  consumables  related  to  our  products,  including  with  respect  to  SMRT  Cells, 
reagents, Sequel II/IIe Systems, Revio, Onso, and other SMRT Cell, HiFi, and SBB products under development, and including 
any delays or defects in software development or product functionality, the timing and success of the continued rollout and 
scaling of our products may be significantly impacted, which may materially and negatively impact our revenue and gross 
margin. The ability of our customers to successfully utilize our products will also depend on our ability to deliver high quality 
SMRT Cells and reagents. We have designed SMRT Cells and other consumables specifically for the Sequel, Sequel II/IIe, and 
Revio Systems, and  may  need  to  develop  in  the  future,  other  customized  SMRT  Cells  and  consumables  for  our  future 
products. Our production of the SMRT Cells for the Sequel and Sequel II/IIe Systems has been and may in the future, including 
with respect to the Revio system, be below desired levels and yields, and we have experienced and may experience in the 
future manufacturing delays, product or quality defects, SMRT Cell variability, and other issues. For example, the COVID–19 
pandemic outbreak has impacted and could result in more pronounced impacts to our manufacturing and our ability to supply 
products. The performance of our consumables is critical to our customers’ successful utilization of our products, and any 
defects  or  performance  issues  with  our  consumables  would  adversely  affect  our  business.  All  of  the  foregoing  could 
materially  negatively  impact  our  ability  to  sell  our  products  or  result  in  other  material  adverse  effects  on  our  business, 
operations, financial condition, operations and prospects. 

The development of our products is complex and costly. Problems in the design or quality of our products may have a material 
and  adverse  effect  on  our  brand,  business,  financial  condition,  and  operating  results,  and  could  result  in  us  losing  our 
certifications from the International Organization for Standardization (“ISO”). If we were to lose ISO certification, then our 
customers might choose not to purchase products from us and this could adversely impact our ability to develop products 
approved for clinical uses. Unanticipated problems with our products could divert substantial resources, which may impair 
our ability to support our new and existing products and could substantially increase our costs. If we encounter development 
challenges or discover errors in our products late in our development cycle, including during external beta testing, we may be 
forced to undertake design and/or production changes, delay product shipments or the scaling of manufacturing or supply. 
The completion of the production and external testing of our beta systems may also take longer than currently planned, cost 
more than currently expected and the scientific and technical validation may not be completed on our currently expected 
timelines or at all. Such testing may also expose fundamental flaws in our products that may cause us to abandon the further 
development of such products. 

If the continued rollout of our current and future products, including with respect to the SMRT Cell, the Sequel II/IIe, Revio, 
and Onso Systems, is delayed or is not successful or less successful than anticipated, then we may not be able to achieve 
an acceptable return, if any, on our substantial research and development efforts, and our business may be materially and 
adversely affected. The expenses or losses associated with delayed or unsuccessful product development or lack of market 
acceptance  of  our  existing  and  new  products,  including  the  SMRT  Cell,  Sequel  II/IIe  Systems,  Revio, and  Onso,  could 
materially and adversely affect our business, operations, financial condition, and prospects. 

Our research and development efforts may not result in the benefits that we anticipate, and our failure to successfully market, 
sell,  and  commercialize  our  current  and  future  products  could  have  a  material  adverse  effect  on  our  business,  financial 
condition and results of operations. 

We have dedicated significant resources to developing our current products, including sequencing systems and consumables 
based on our proprietary SMRT sequencing technology and our Sequel and Sequel II/IIe Systems. We are also engaged in 
substantial  and  complex  research  and  development  efforts,  which,  if  successful,  may  result  in  the  introduction  of  new 
products in the future, including in connection with the SMRT Cell, the Sequel II/IIe Systems and Revio, in addition to Onso and 
other SBB products currently under development. Our research and development efforts are complex and require us to incur 
substantial  expenses.  We  may  not  be  able  to  develop,  manufacture  and  commercialize  new  products,  obtain  regulatory 
approval if necessary, or achieve an acceptable return, if any, on our research and development efforts and expenses or joint 
research and development efforts with partners. Our joint research and development efforts with partners require significant 
management  attention  and  operational  resources.  If  we  are  unable  to  successfully  manage  such  joint  research  and 
development  efforts,  our  future  results  may  be  adversely  impacted.  For  example,  in  January 2021,  we  entered  into  a 

16 

 
development  agreement  with  Invitae,  which  was  amended  and  restated  on  June 24,  2022  (the  “Invitae  Development 
Agreement”),  regarding  a  multi-year  collaboration  for  the  development  of  a  production-scale  high-throughput  sequencing 
platform.  While  we  anticipate  that  in  connection  with  the  Invitae  Development  Agreement,  we  will  continue  to  receive 
feedback, input and insight from Invitae in connection with our intended development of new high-throughput sequencing 
systems, such feedback is not contractually required and Invitae has no contractual right to participate in decisions regarding 
the  development  program  for  such  new  sequencing  systems.  Invitae  is  not  contractually  obligated  to  reimburse  us  for 
development costs under the Invitae Development Agreement. We do not expect to receive any additional revenue under the 
Invitae  Development  Agreement  apart  from  potential  purchases  by  Invitae  of  our  instruments  and  consumables.  In 
consideration of non-refundable Development Costs (as defined in the Invitae Development Agreement) paid by Invitae to us 
pursuant to the Invitae Development Agreement, we have provided Invitae with credits in connection with Invitae’s anticipated 
purchase of currently available and in-development sequencing systems (instruments and consumables). In addition, subject 
to certain conditions, Invitae will be entitled to most favored pricing for our Sequel IIe systems and certain in-development 
systems,  including  the  Revio system  and  we  may  be  required  to  sell  instruments  to  Invitae  at  below-market  prices. 
Furthermore, we will need to continue to expand our internal capabilities or seek new partnerships or collaborations, or both, 
in order to successfully develop, market, sell and commercialize our products for and in the markets we seek to reach. If we 
are unable to do so or are delayed, then this could materially and adversely affect our business, operations, financial condition, 
and prospects. 

We must successfully manage new product introductions and transitions, including with respect to the SMRT Cell, the Sequel 
II/IIe Systems, and the development of the Revio HiFi long-read sequencing system and the Onso SBB short-read sequencing 
system, and we may incur significant costs during these transitions and development, and these efforts may not result in the 
benefits we anticipate. 

If  our  products  and  services  fail  to  deliver  the  performance,  scalability  or  results  expected  by  our  current  and  future 
customers, or are not delivered on a timely basis, our reputation and credibility may suffer, our current and future sales and 
revenue may be materially harmed and our business may not succeed. For instance, if we are not able to realize the benefits 
we anticipate from the development and commercialization of the SMRT Cell, Sequel II/IIe Systems, the Revio HiFi long-read 
sequencing system, and the Onso SBB short-read sequencing system, and any future products that may be developed for 
research, medical and clinical uses, it could have a material adverse effect on our business, financial condition and results 
of  operations.  In  addition,  the  introduction  of  future  products,  including  with  respect  to  future  long-read  and  short-read 
products,  and  related  consumables,  has  and  may  in  the  future  lead  to  our  limiting  or  ceasing  development  of  further 
enhancements to our existing products as we focus our resources on new products, and has resulted and could in the future 
result  in  reduced  marketplace  acceptance  and  loss  of  sales  of  our  existing  products,  materially  adversely  affecting  our 
revenue and operating results. The introduction of new products, including the recent announcement of our Revio system, 
has had and may in the future also have a negative impact on our revenue in the near-term as our current and future customers 
have delayed or cancelled and may in the future delay or cancel orders of existing products in anticipation of new products 
and we may also be pressured to decrease prices for our existing products. Our experience in managing product transitions 
is  limited,  and  we  have  experienced,  and may in  the  future  experience,  difficulty  in  managing  or  forecasting  customer 
reactions, purchasing decisions or transition requirements with respect to newly launched products. We have incurred and 
may continue to incur significant costs in completing these transitions, including costs of write-downs of our products, as 
current or future customers transition to new products. If we do not successfully manage these product transitions, including 
with respect to the SMRT Cell, Sequel II/IIe Systems, the Revio and Onso Systems, and any future long-read and short-read 
products, our business, operations, financial condition, and prospects may be materially and adversely affected. 

Our business may be adversely affected by health epidemics, including the ongoing COVID-19 pandemic. 

Our  business  has  been  and  could  be  further  adversely  impacted  by  the  effects  of  COVID-19  or  other  epidemics  or 
pandemics. Although it is not possible at this time to estimate the impact that health epidemics, including the ongoing COVID-
19 pandemic, could have on our business, the continued spread of pandemics and the measures taken by the governments 
of countries affected could disrupt the supply chain and the manufacture of our products. 

17 

 
Our manufacturing partners and suppliers have been and could continue to be disrupted by conditions related to COVID-19 
or other epidemics or pandemics, possibly resulting in disruption to the production of our products. If our manufacturing 
partners or suppliers are unable or fail to fulfill their obligations to us for any reason, we may not be able to manufacture our 
products and satisfy customer demand or our obligations under sales agreements in a timely manner, and our business could 
be harmed as a result. There is significant uncertainty relating to the long-term effect of COVID-19 on our business. Infections 
may resurge or become more widespread and any ensuing disruptions to business activities or supply chains could have a 
negative impact on our business, financial condition, and operating results. Because our semiconductor manufacturers are 
located in a region where immunization rates in certain communities may be low, new and emerging variants of COVID-19 
could  impact  workforce  availability  at  those  locations  and  disrupt  supply.  For  example,  the  Chinese  government  may  re-
impose lockdowns or similar measures to combat the spread of COVID-19 and such measures have had, and may continue 
to have in the future, a negative impact on manufacturing and/or supply chains, as well as customer demand for our products 
and demand through certain distributors. 

The  COVID-19  pandemic  has  caused  us  to  modify  our  business  practices,  including  limiting  certain  of  our  commercial 
operations and limiting certain employees from working in the office. We have offered, and may plan to continue to offer, a 
significant percentage of our employees flexibility in the amount of time they work in an office, which could adversely impact 
the productivity of certain employees and harm our business, including our future operating results. This may also present 
risks for our strategy and may present operational, cybersecurity, and workplace culture challenges that may adversely affect 
our business. 

Even after the COVID-19 pandemic has subsided, we may continue to experience an adverse impact to our business as a 
result  of  its  global  economic  impact,  including  recessionary  effects  and  inflationary  pressures.  Specifically,  difficult 
macroeconomic conditions, such as decreases in discretionary capital expenditure spending, changes to the government 
funding  environment,  a  reduction  in  or  the  lapsing  of  COVID-19-related  governmental  stimulus  measures,  increased  and 
prolonged unemployment or a decline in consumer confidence as a result of the COVID-19 pandemic, as well as limited or 
significantly reduced points of access of our products, could have a continuing adverse effect on the demand for some of 
our  products  and,  consequently,  related  maintenance  and  support  services.  The  degree  of  impact  of  COVID-19  on  our 
business will depend on several factors, such as the duration and the extent of the pandemic, the risk of waning immunity 
among persons already vaccinated and an increase in fatigue or skepticism with respect to initial or booster vaccinations, as 
well as actions taken by governments, businesses, and consumers in response to the pandemic, all of which continue to 
evolve and remain uncertain at this time. 

Significant changes to our leadership team and the resulting management transitions might harm our future operating results. 

We have experienced significant changes to our leadership team. Our President and Chief Executive Officer Christian O. Henry 
was appointed effective September 14, 2020, succeeding Dr. Michael Hunkapiller who  retired on December 31, 2020. Our 
Chief Financial Officer Susan G. Kim was appointed effective September 28, 2020, succeeding Susan K. Barnes who retired 
on  August 7,  2020.  Our  Chief  Operating  Officer  Mark  Van  Oene  was  appointed  effective  January 8,  2021.  Jeff  Eidel  was 
appointed Chief Commercial Officer effective August 16, 2022, succeeding Peter Fromen who resigned effective May 20, 
2022. Also, our Vice President and Chief Accounting Officer Michele Farmer was appointed effective May 17, 2021, and our 
Chair of the Board Dr. John F. Milligan was appointed effective September 14, 2020. 

Although we believe these leadership transitions are in the best interest of our stakeholders, these transitions may result in 
the  loss  of  personnel  with  deep  institutional  or  technical  knowledge.  Further,  the  transition  could  potentially  disrupt  our 
operations  and  relationships  with  employees,  suppliers,  partners,  and  customers  due  to  added  costs,  operational 
inefficiencies,  decreased  employee  morale  and  productivity  and  increased  turnover.  We  must  successfully  recruit  and 
integrate  our  new  leadership  team  members  within  our  organization  to  achieve  our  operating  objectives;  as  such,  the 
leadership transition may temporarily affect our business performance and results of operations while the new members of 
our leadership team become familiar with our business. In addition, our competitors may seek to use this transition and the 
related potential disruptions to gain a competitive advantage over us. Furthermore, these changes increase our dependency 
on the other members of our leadership team that remain with us, who are not contractually obligated to remain employed 
with us and may leave at any time. Any such departure could be particularly disruptive given that we are already experiencing 
leadership transitions and, to the extent we experience additional management turnover, competition for top management is 
high such that it may take some time to find a candidate that meets our requirements. Our future operating results depend 
substantially upon the continued service of our key personnel and in significant part upon our ability to attract and retain 
qualified management personnel. If we are unable to mitigate these or other similar risks, our business, results of operations 
and financial condition may be materially and adversely affected. 

18 

 
We depend on the continuing efforts of our senior management team and other key personnel. If we lose members of our 
senior  management team or  other key personnel  or are unable  to  successfully  retain,  recruit  and  train  qualified  scientists, 
engineers, sales personnel and other employees, our ability to maintain, develop and commercialize our products could be 
harmed and we may be unable to achieve our goals. 

Our  success  depends  upon  the  continuing  services  of  members  of  our  senior  management  team  and  scientific  and 
engineering personnel. In particular, our scientists and engineers are critical to our technological and product innovations, 
and  we  will  need  to  hire  additional  qualified  personnel.  Our  industry,  particularly  in  the  San  Francisco  Bay  Area,  is 
characterized by high demand and intense competition for talent, and the turnover rate has been and may continue to be 
high.  We  compete  for  qualified  management  and  scientific  personnel  with  other  life  science  companies,  academic 
institutions and research institutions, particularly those focusing on genomics. This competition has become exacerbated by 
the increase in employee resignations in 2021 and continued high rates of employee turnover continuing through 2022 that 
have been experienced by us and reported by employers nationwide. In addition, we have experienced significant turnover in 
our senior management team in recent periods. To induce valuable employees to remain at our company, in addition to salary 
and cash incentives, we have issued stock options and restricted stock units that vest over time. The value to employees of 
stock options and restricted stock units that vest over time may be significantly affected by movements in our stock price 
that are beyond our control and may at any time be insufficient to counteract more lucrative offers from other companies. 
We may face challenges in retaining and recruiting such individuals due to sustained declines in our stock price that could 
reduce the retention value of equity awards. The loss of qualified employees, or an inability to attract, retain, and motivate 
employees,  could  prevent  us  from  pursuing  collaborations  and  materially  and  adversely  affect  our  support  of  existing 
products, product development and launches, business growth prospects, results of operations and financial condition. In 
addition, we will need to continue to recruit, hire and retain sales personnel to support the commercialization of our existing 
and new products. Our employees could leave our company with little or no prior notice and would be free to work for a 
competitor. In addition, changes to U.S. immigration policies, particularly to H-1B and other visa programs, could restrain the 
flow of technical and professional talent into the U.S. and may inhibit our ability to hire qualified personnel. If one or more of 
our senior executives or other key personnel were unable or unwilling to continue in their present positions, we may not be 
able to replace them easily or at all, and other senior management may be required to divert attention from other aspects of 
the business. In addition, we do not have “key person” life insurance policies covering any member of our management team 
or  other  key  personnel.  Further,  our  vaccination  and  return  to  office  protocols  related  to  COVID-19  may  also  impact  the 
recruitment and retention of key employees. The loss of any of these individuals or any inability to attract or retain qualified 
personnel, including scientists, engineers, sales personnel and others, could prevent us from pursuing collaborations and 
materially and adversely affect our support of existing products, product development and introductions, business growth 
prospects, results of operations and financial condition. 

Our  success  is  highly  dependent  on  our  ability  to  further  penetrate  nucleic  acid  sequencing  applications  as  well  as  on  the 
growth and expansion of the demand for our products. If our products fail to achieve and sustain sufficient market acceptance, 
we will not generate expected revenue and our business may not succeed. 

Although  nucleic  acid  sequencing  technology  is  well-established,  our  SMRT  Sequencing  technology  is  relatively  new  and 
evolving. We cannot be sure that our current or future products will gain acceptance in the marketplace at levels sufficient to 
support  our  costs.  Our  success  depends,  in  part,  on  our  ability  to  expand  overall  demand  for  nucleic  acid  sequencing  to 
include new applications that are not practicable with other current technologies and to introduce new products that capture 
a  larger  share  of  growing  overall  demand  for  sequencing.  To  accomplish  this,  we  must  successfully  commercialize,  and 
continue development of, our proprietary SMRT Sequencing technology for use in a variety of life science and other research 
applications,  including  uses  by  academic,  government  and  clinical  laboratories,  as  well  as  pharmaceutical,  diagnostic, 
biotechnology, and agriculture companies, among others. However, we may be unsuccessful in these efforts and the sale 
and commercialization of the SMRT Cell, Sequel II/IIe Systems, and anticipated sale and commercialization of Revio and 
Onso, and related products may not grow sufficiently to cover our costs. 

There can be no assurance that we will be successful in adding new products or securing additional customers for our current 
and  future  products,  including  with  respect  to  the  SMRT  Cell,  Sequel  II/IIe  Systems,  Revio and  Onso.  If  we  are  unable  to 
successfully develop SBB technology and sell acquired technology products, we may fail to achieve our strategic commercial 
initiatives  in  connection  with  the  planned  release  of  new  products  and  anticipated  entry  into  new  markets.  Our  ability  to 
further  penetrate  existing  applications  and  any  new  applications  depends  on  a  number  of  factors,  including  the  cost, 
performance  and  perceived  value  associated  with  our  products,  as  well  as  customers’  willingness  to  adopt  a  different 
approach  to  nucleic  acid  sequencing.  Potential  customers  may  have  already  made  significant  investments  in  other 
sequencing technologies and may be unwilling to invest in new technologies. We are experiencing pricing pressures caused 
by industry competition and increased demand for lower-priced instruments and lower operational costs. We have limited 
experience commercializing and selling products outside of the academic and research settings, and we cannot guarantee 
success  in  acquiring  additional  customers.  Furthermore,  we  cannot  guarantee  that  our  products  will  be  satisfactory  to 
potential customers or that our products will perform in accordance with customer expectations. 

19 

 
Nucleic acid sequencing applications are new and dynamic, and there can be no assurance that they will develop as quickly 
as  we  anticipate,  that  they  will  reach  their  full  potential  or  that  our  products  will  be  appropriate  or  competitive  for  these 
applications. As a result, we may be required to refocus our marketing efforts, and we may have to make changes to the 
specifications of our products to enhance our ability to enter particular applications more quickly. We may also need to delay 
full-scale commercial deployment of new products as we develop them in order to perform quality control and early access 
user  testing.  We  also  need  to  maintain  reliable  supply  chains  for  the  various  components  in  our  new  products  and 
consumables to support large-scale commercial production. Even if we are able to implement our technology successfully, 
we  and/or  our  sales  and  distribution  partners  may  fail  to  achieve  or  sustain  market  acceptance  of  our  current  or  future 
products across the full range of our intended life science and other applications. We need to continue to expand and update 
our internal capabilities or to collaborate with other partners, or both, in order to successfully expand sales of our products 
in the applications that we seek to reach, which we may be unable to do at the scale required to support our business. 

If the demand for our products grows more slowly than anticipated, if we are unable to successfully scale or otherwise ensure 
sufficient manufacturing capacity for new products to meet demand, if we are not able to successfully market and sell our 
products, if competitors develop better or more cost-effective products, if our product launches and commercialization are 
not successful, or if we are unable to further grow our customer base or do not realize the growth with existing customers 
that we are expecting, our current and future sales and revenue may be materially and adversely harmed, or we may recognize 
an impairment loss, and our business may not succeed. 

We rely on other companies for the manufacture of certain components and sub-assemblies and intend to outsource additional 
sub-assemblies in the future, some of which are sole sources. We may not be able to successfully scale the manufacturing 
process necessary to build and test multiple products on a full commercial basis, which could materially harm our business. 

Our products are complex and involve a large number of unique components, many of which require precise manufacturing. 
The  nature  of  our  products  requires  customized  components  that  are  currently  available  only  from  a  limited  number  of 
sources, and in some cases, single sources. We have chosen to source certain critical components from a single source, 
including suppliers for our SMRT Cells, reagents, and instruments. We cannot assure you that product supplies will not be 
limited or interrupted, especially with respect to our sole source third-party manufacturing and supply collaborators, or that 
product supplies will be of satisfactory quality or continue to be available at acceptable prices. In particular, any replacement 
of  our  manufacturers  could  require  significant  effort  and  expertise  because  there  may  be  a  limited  number  of  qualified 
replacements.  We  may  be  unable  to  negotiate  binding  agreements  with  our  current  and  future  sole  source  third-party 
manufacturing and supply collaborators or, in the event that such collaborators’ services become interrupted for any reason, 
find replacement manufacturers to support our development and commercial activities at commercially reasonable terms. 
We do not always have arrangements in place for a redundant or second-source supply for our sole source vendors in the 
event they cease to provide their products or services to us or fail to provide sufficient quantities in a timely manner. If we 
are required to purchase these components from alternative sources, it could take several months or longer to qualify the 
alternative sources. If we are unable to source these product components from sole-source third-party manufacturing and 
supply collaborators for any reason, including in connection with acts of terrorism, hostilities, military conflict and acts of 
war, including between China and Taiwan, or secure a sufficient supply of these product components on a timely basis, or if 
these  components  do  not  meet  our  expectations  or  specifications  for  quality  and  functionality,  our  operations  and 
manufacturing would be materially and adversely affected, we could be unable to meet customer demand and our business 
and results of operations may be materially and adversely affected. 

The operations of our third-party manufacturing partners and suppliers have been and could continue to be disrupted by 
conditions unrelated to our business or operations or that are beyond our control, including but not limited to international 
trade  restrictions,  inflation,  supply  chain  disruptions,  and  conditions  related  to  COVID-19  or  other  epidemics.  If  our 
manufacturing partners or suppliers are unable or fail to fulfill their obligations to us for any reason, we may not be able to 
manufacture our products and satisfy customer demand or our obligations under sales agreements in a timely manner, and 
our business could be harmed as a result. For example, the global shortage of semiconductors, which has been reported 
since early 2021, has caused challenges for us in our supply chain and resulted in some cost increases that have and may 
continue to adversely impact margins. During these periods of shortages or delays, the price of components may increase, 
or the components may not be available at all. Our suppliers have raised their prices and may continue to raise prices that 
we  may  not  be  able  to  pass  on  to  our  customers,  which  could  adversely  affect  our  business,  including  our  competitive 
position, market share, revenues, and profit margins in material ways. We may not be able to secure enough components at 
reasonable prices or of acceptable quality to build new products in a timely manner in the quantities or configurations needed. 
For example, the Chinese government may re-impose lockdowns or similar measures to combat the spread of COVID-19 and 
these measures have had, and may continue to have in the future, a negative impact on manufacturing and/or supply chains, 
in addition to customer demand for our products and demand through certain distributors. If as a result of global economic 
or  political  instability,  such  as  the  political  uncertainty  associated  with  an  escalation  of  the  war  in  Ukraine,  potential 
uncertainty related to Taiwan and its relationship with China, other disease outbreaks, or supply issues, we or our contractors 
could experience shortages, business disruptions or delays for materials sourced or manufactured in the affected countries, 
and  their  ability  to  supply  us  with  instruments  or  product  components  may  be  affected.  From  time  to  time,  certain 

20 

 
components of our systems and reagents may reach the end of their life cycles or become obsoleted by our suppliers, and 
we would have to procure alternative sources for these end-of-life products. If we encounter delays or difficulties in securing 
the quality and quantity of materials we require for our products, our supply chain would be interrupted, which would adversely 
affect sales. If any of these events occur, our business and operating results could be harmed. Accordingly, if any of the 
foregoing occurs, our ability to commercialize our products, revenue and gross margins could suffer until lockdowns from 
COVID-19 infections are reduced, supply issues or business disruptions are resolved and/or other sources can be developed. 

In addition, because our semiconductor suppliers are in regions that may have communities with low vaccination rates, the 
Omicron variant of COVID-19, or any variants that evolve in the future, could lead to increased infections among workers that 
could further disrupt the supply chain. Our current manufacturing process is characterized by long lead times between the 
placement of orders for and delivery of our products. If we do not accurately anticipate our needs or if we receive insufficient 
components to manufacture our products on a timely basis to meet customer demand, our sales and our gross margin may 
be adversely affected, and our business could be materially harmed. If we are unable to reduce our manufacturing costs and 
establish and maintain reliable, high-volume manufacturing suppliers as we scale our operations and expand our product 
offerings, our business, operations, financial condition, and prospects could be materially and adversely harmed. 

We may be unable to consistently manufacture our instruments and consumables, including SMRT Cells and reagents, to the 
necessary specifications or in quantities necessary to meet demand at an acceptable cost or at an acceptable performance 
level. 

In order to successfully generate revenue from our products, we need to supply our customers with products that meet their 
expectations for quality and functionality in accordance with established specifications. Our customers have experienced 
variability in the performance of our products. We have experienced and may continue to experience delays, quality issues or 
other difficulties leading to customer dissatisfaction with our products. Our production of SMRT Cells and reagents involves 
a long and complex manufacturing process and has been and may in the future be below desired yields and resulting output 
levels.  We  have  experienced  and  may  experience  in  the  future  manufacturing  delays,  product  defects,  variability  in  the 
performance of SMRT Cells and other products, inadequate reserves for inventory, or other issues. 

There  is  no  assurance  that  we  will  be  able  to  manufacture  our  products  so  that  they  consistently  achieve  the  product 
specifications and quality that our customers expect, including any products developed for clinical uses. Problems in the 
design or quality of our products, including low manufacturing yields of SMRT Cells, or sub-performing reagent lots may have 
a material adverse effect on our brand, business, financial condition, and operating results, and could result in us losing our 
ISO certifications. If we were to lose our ISO certifications, then our customers might choose not to purchase products from 
us. There is also no assurance that we will be able to increase manufacturing yields and decrease costs, particularly if high 
rates of inflation continue, or that we will be successful in forecasting customer demand or manufacturing and supply costs, 
or that product supplies, including reagents or integrated chips, will not be limited or interrupted, or will be of satisfactory 
quality  or  continue  to  be  available  at  acceptable  prices.  Furthermore,  while  we  are  undertaking  efforts  to  increase  our 
manufacturing  scale  and  capability,  we  may  not  be  able  to  increase  manufacturing  to  meet  anticipated  demand  or  may 
experience downtime in our manufacturing facilities, including, for example, if we experience increased cases of COVID-19 
among our employees, or if our suppliers are unable to meet our increased demand at a time when the supply chain is under 
duress due to potential dislocations and disruptions in product and employee availability due to COVID-19. An inability to 
manufacture products and components that consistently meet specifications, in necessary quantities and at commercially 
acceptable costs, will have a negative impact, and may have a material adverse effect on our business, product development 
timelines, financial condition and results of operations. 

Rapidly changing technology in life sciences and research diagnostics could make our products obsolete unless we continue 
to develop, manufacture and commercialize new and improved products and pursue new opportunities. 

Our  industry  is  characterized  by  rapid  and  significant  technological  changes,  frequent  new  product  introductions  and 
enhancements  and  evolving  industry  standards.  Our  future  success  depends  on  our  ability  to  continually  improve  our 
products, to develop and introduce new products that address the evolving needs of our customers on a timely and cost-
effective basis and to pursue new opportunities. These new opportunities may be outside the scope of our proven expertise 
or in areas where demand is unproven, and new products and services developed by us may not gain market acceptance or 
may not adequately perform in order to capture market share. Our inability to develop and introduce new products and to 
gain market acceptance of our existing and new products could harm our future operating results. Unanticipated difficulties 
or delays in replacing existing products with new products or in commercializing our existing or new products in sufficient 
quantities and of acceptable quality to meet customer demand, including with respect to the SMRT Cell, Sequel II/IIe Systems, 
Revio and Onso, could diminish future demand for our products and may materially and adversely harm our future operating 
results. 

21 

 
The size of the markets for our products, including our Revio and Onso instruments, may be smaller than estimated, and new 
market opportunities may not develop as quickly as we expect, or at all, limiting our ability to successfully sell our products. 

The market for sequencing systems and consumables products is evolving, making it difficult to accurately predict the size 
of the markets for our current and future products, including our Revio and Onso instruments. Our estimates of the total 
addressable market for our current and future products are based on a number of internal and third-party estimates and 
assumptions that may be incorrect, including the assumptions that academic, governmental, corporate, or other sources of 
funding will continue to be available to life sciences researchers at times and in amounts necessary to allow them to purchase 
our products. In addition, sales of new products may take time to develop and mature and we cannot be certain that these 
market opportunities will develop as we expect. While we believe our assumptions and the data underlying our estimates of 
the total addressable market for our products are reasonable, these assumptions and estimates may not be correct and the 
conditions supporting our assumptions or estimates, or those underlying the third-party data we have used, may change at 
any time, thereby reducing the accuracy of our estimates. As a result, our estimates of the total addressable market and 
growth opportunities for our products may be incorrect. 

The future growth of the market for our current and future products depends on many factors beyond our control, including 
recognition and acceptance of our products by the research and scientific communities, the growth, prevalence and costs of 
competing  products  and  solutions  and  the  development  of  robust  ecosystems  supporting  our  products  and  their 
methodologies.  For  example,  our  long-read  sequencers,  such  as  Revio,  require  tools  for  effective,  high  quality  sample 
collection and preparation as well as advanced bioinformatic tools to process results; if these tools are unavailable to our 
customers, whether at a reasonable cost or at all, the market acceptance and growth of our long-read sequencers, like Revio, 
may be negatively impaired. There can be no assurance that our current or future products will gain traction in the market. If 
the markets for our current and future products are smaller than estimated or do not develop as we expect, our growth may 
be limited, and it could materially and adversely affect our business, operations, financial condition and prospects. 

Increased market adoption of our products by customers may depend on the availability of sample preparation and informatics 
tools, some of which may be developed by third parties. 

Our commercial success may depend in part upon the development of sample preparation and software and informatics 
tools by third parties for use with our products. We cannot guarantee that product supplies, including reagents, will not be 
limited or interrupted, or will be of satisfactory quality or continue to be available at acceptable prices, or that third parties 
will develop tools that our current and future customers will find useful with our products, or that customers will adopt such 
third-party tools on a timely basis or at all. A lack of complementary sample preparation and informatics tools, or delayed 
updates of such tools, may impede the adoption of our products and may materially and adversely impact our business. 

We operate in a highly competitive industry and if we are not able to compete effectively, our business and operating results 
will likely be harmed. 

There are a significant number of companies offering nucleic acid sequencing products and/or services, including Illumina, 
BGI Genomics, Thermo, ONT Ltd., Roche, Bionano, and Qiagen. Other companies recently entering the market include Ultima 
Genomics, Element Biosciences and Singular Genomics. Many of these companies currently have greater name recognition, 
more substantial intellectual property portfolios, longer operating histories, significantly greater financial, technical, research 
and/or  other  resources,  more  experience  in  new  product  development,  larger  and  more  established  manufacturing 
capabilities and marketing, sales, and support functions, and/or more established distribution channels to deliver products 
to customers than we do. These companies may be able to respond more quickly and effectively than we can to new or 
changing opportunities, technologies, standards, or customer requirements. 

There are also several companies that are in the process of developing or have already developed and commercialized new, 
competing or potentially competing technologies, products and/or services, including ONT Ltd. and its subsidiaries, against 
whom we have filed complaints for patent infringement in the U.S. District Court for the District of Delaware and, previously, 
with the U.S. International Trade Commission, in the High Court of England and Wales and in the District Court of Mannheim, 
Germany.  ONT  Ltd. previously  filed  claims  against  us  in  the  High  Court  of  England  and  Wales  and  the  District  Court  of 
Mannheim, Germany, also for patent infringement, and its subsidiary, Oxford Nanopore Technologies, Inc. (“ONT Inc.”), filed 
counterclaims  against  us  in  the  U.S.  District  Court  for  the  District  of  Delaware  seeking  declaratory  judgements  of  non-
infringement,  invalidity  and  unenforceability  of  the  asserted  patents,  as  well  as  antitrust,  false  advertising  and  unfair 
competition  counterclaims  that  were  subsequently  dismissed  by  that  court.  Roche  is  developing  potentially  competing 
sequencing  products.  Increased  competition  may  result  in  pricing  pressures,  which  could  harm  our  sales,  profitability  or 
market share. Our failure to further enhance our existing products and to introduce new products to compete effectively could 
materially and adversely affect our business, operations, financial condition, and prospects. 

22 

 
We may be unable to successfully increase sales of our current products or market and sell our future products. 

Our ability to achieve profitability depends, in part, on our ability to attract customers for our current and future products 
including Revio and Onso, and we may be unable to effectively market or sell our products or find appropriate partners to do 
so.  To  perform  sales,  marketing,  distribution,  and  customer  support  functions  successfully,  we  face  a  number  of  risks, 
including: 

• 

• 

• 

• 

• 

our ability to attract, retain and manage qualified sales, marketing, and service personnel necessary to expand market 
acceptance for our technologies; 

the performance and commercial availability expectations of our existing and potential customers with respect to 
new and existing products; 

availability of potential sales and distribution partners to sell our technologies, and our ability to attract and retain 
such sales and distribution partners; 

the  time  and  cost  of  maintaining  and  growing  a  specialized  sales,  marketing  and  service  force  for  a  particular 
application, which may be difficult to justify in light of the revenue generated; and 

our sales, marketing and service force may be unable to execute successful commercial activities. 

We have enlisted and may continue to enlist third parties to assist with sales, distribution and customer support. There is no 
guarantee that we will be successful in attracting desirable sales and distribution partners, that we will be able to enter into 
arrangements with such partners on terms favorable to us or that we will be able to retain such partners on a going-forward 
basis. If our sales and marketing efforts, or those of any of our third-party sales and distribution partners, are not successful, 
or  our  products  do  not  perform  in  accordance  with  customer  expectations,  our  technologies  and  products  may  not  gain 
market acceptance, which could materially and adversely impact our business, operations, financial condition, and prospects. 

Large purchases by a limited number of customers represent a significant portion of our revenue, and any loss or delay of 
expected purchases has resulted, and in the future could result, in material quarter-to-quarter fluctuations of our revenue or 
otherwise adversely affect our results of operations. 

We  receive  a  significant  portion  of  our  revenue  from  a  limited  number  of  customers.  For  example, for  the  years  ended 
December 31,  2022,  2021,  and  2020,  one  of  our  customers,  who  is  our  primary  distributor  in  China,  accounted  for 
approximately 12%, 13%, and 14% of our total revenue, respectively. Many of these customers make large purchases on a 
purchase-order  basis  rather  than  pursuant  to  long-term  contracts.  As  a  consequence  of  the  concentrated  nature  of  our 
customer  base  and  their  purchasing  behavior,  our  quarterly  revenue  and  results  of  operations  have  fluctuated,  and  may 
fluctuate  in  the  future,  from  quarter  to  quarter  and  are  difficult  to  forecast.  For  example,  the  cancellation  of  orders  or 
acceleration or delay in anticipated product purchases or the acceptance of shipped products by our larger customers has 
materially affected, and in the future could materially affect, our revenue and results of operations in any quarterly period. We 
have  been,  and  may  in  the  future  be,  unable  to  sustain  or  increase  our  revenue  from  our  larger  customers,  or  offset  any 
discontinuation or decrease of purchases by our larger customers with purchases by new or other existing customers. To 
the extent one or more of our larger customers experience significant financial difficulty, bankruptcy or insolvency, this could 
have a material adverse effect on our sales and our ability to collect on receivables, which could materially and adversely 
harm our financial condition and results of operations. 

In addition, many of our customers, including some of our larger customers, have negotiated, or may in the future negotiate, 
volume-based discounts or other more favorable terms from us or our sales and distribution partners, which can and have 
had a negative effect on our gross margins or revenue. 

We expect that such concentrated purchases will continue to contribute materially to our revenue for the foreseeable future 
and that our results of operations may fluctuate materially as a result of such larger customers’ buying patterns. In addition, 
we may see consolidation of our customer base. The loss of one of our larger customers, a significant delay or reduction in 
its  purchases,  or  any  volume-based  discount  or  other  more  favorable  terms  that  we  or  our  sales  and  distribution 
partner(s) may  agree  to  provide,  in  light  of  the  aggregated  purchase  volume  or  buying  power  resulting  from  such 
consolidation,  has  harmed,  and  in  the  future  could  harm,  our  business,  financial  condition,  results  of  operations  and 
prospects. 

Our products are highly complex, have recurring support requirements and could have unknown defects or errors, which may 
give rise to claims against us or divert application of our resources from other purposes. 

Products  using  our  SMRT  sequencing  technology  are  highly  complex  and  may  develop  or  contain  undetected  defects  or 
errors. Our customers have previously experienced reliability issues with our existing products, including the Sequel System 
and the Sequel II/IIe Systems. In addition, it is possible our customers could experience reliability issues with current or future 
products, including the Sequel II/IIe, Onso, and Revio Systems. Despite internal and external testing, defects, or errors may 
arise  in  our  products,  which  could  result  in  a  failure  to  obtain,  maintain,  or  increase  market  acceptance  of  our  products, 

23 

 
 
 
 
 
 
 
 
 
diversion of development resources, injury to our reputation and increased warranty, service, and maintenance costs. New 
products, including  Revio and  Onso,  or  enhancements  to  our  existing  products,  including the  SMRT  Cell  and  Sequel  II/IIe 
Systems,  in  particular  may  contain  undetected  errors  or  performance  problems  that  are  discovered  only  after  delivery  to 
customers. If our products have reliability or other quality issues or require unexpected levels of support in the future, the 
market acceptance and utilization of our products may not grow to levels sufficient to support our costs and our reputation 
and  business  could  be  harmed.  Low  utilization  rates  of  our  products  could  cause  our  revenue  and  gross  margins  to  be 
adversely affected. We provide a warranty for our sequencing instruments and consumables, which is generally limited to 
replacing, repairing, or at our option, giving credit for any sequencing instrument or consumable with defects in material or 
workmanship.  Service  contracts  for  our  sequencing  instruments  may  be  separately  purchased.  Defects  or  errors  in  our 
products  may  also  discourage  customers  from  purchasing  our products. The  costs  incurred in  correcting  any  defects  or 
errors may be substantial and could materially and adversely affect our operating margins. If our service and support costs 
increase, our business and operations may be materially and adversely affected. 

In addition, such defects or errors could lead to the filing of product liability claims against us or against third parties whom 
we may have an obligation to indemnify against such claims, which could be costly and time-consuming to defend and result 
in substantial damages. Although we have product liability insurance, any product liability insurance that we have or procure 
in the future may not protect our business from the financial impact of a product liability claim. Moreover, we may not be able 
to  obtain  adequate  insurance  coverage  on  acceptable  terms.  Any  insurance  that  we  have  or  obtain  will  be  subject  to 
deductibles  and  coverage limits.  A  product  liability  claim  could  have  a  material  adverse effect  on  our  business,  financial 
condition, and results of operations. 

A significant portion of our sales depends on customers’ spending budgets that may be subject to significant and unexpected 
variation which could have a negative effect on the demand for our products. 

Our instruments represent significant capital expenditures for our customers in research applications. Current and potential 
customers  for  our  current  or  future  products  include  academic  and  government  institutions,  genome  centers,  medical 
research institutions, clinical laboratories, pharmaceutical, agricultural, biotechnology, diagnostic and chemical companies. 
Their spending budgets can have a significant effect on the demand for our products. Spending budgets are based on a wide 
variety of factors, including the allocation of available resources to make purchases, funding from government sources which 
is  highly  uncertain  and  subject  to  change,  the  spending  priorities  among  various  types  of  research  equipment,  policies 
regarding capital expenditures during economically uncertain periods and the impact of COVID-19. Any decrease in capital 
spending or change in spending priorities of our current and potential customers could significantly reduce the demand for 
our products. Any delay or reduction in purchases by current or potential customers or our inability to forecast fluctuations 
in demand could materially and adversely harm our future operating results. 

We may not be able to convert our orders in backlog into revenue. 

Our backlog represents product orders from our customers that we have confirmed but have not been able to fulfill, and, 
accordingly, for which we have not yet recognized revenue. We may not receive revenue from these orders, and any order 
backlog we report may not be indicative of our future revenue. 

Many events can cause an order to be delayed or not completed at all, some of which may be out of our control, including 
the potential impacts from COVID-19 and our suppliers, especially our sole source suppliers, not being able to provide us with 
products or components. If we delay fulfilling customer orders or if customers reconsider their orders, those customers may 
seek to cancel or modify their orders with us. Customers may otherwise seek to cancel or delay their orders even if we are 
prepared to fulfill them. If our orders in backlog do not result in sales, our operating results may suffer. 

Our sales cycles are unpredictable and lengthy, which makes it difficult to forecast revenue and may increase the magnitude 
of quarterly or annual fluctuations in our operating results. 

The sales cycles for our sequencing instruments are lengthy because they represent a major capital expenditure and generally 
require the approval of our customers’ senior management. This may contribute to substantial fluctuations in our quarterly 
or annual operating results, particularly during periods in which our sales volume is low. Because of these fluctuations, it is 
likely that in some future quarters our operating results will fall below the expectations of securities analysts or investors. If 
that happens, the market price of our stock would likely decrease. Past fluctuations in our quarterly and annual operating 
results have resulted in decreases in our stock price. Such fluctuations also mean that investors may not be able to rely on 
our operating results in any particular period as an indication of future performance. Sales to existing customers and the 
establishment of a business relationship with other potential customers is a lengthy process, generally taking several months 
and  sometimes  longer.  Following  the  establishment  of  the  relationship,  the  negotiation  of  purchase  terms  can  be  time-
consuming, including as a result of seasonal factors, as discussed below, and a potential customer may require an extended 
evaluation and testing period. Our sales cycles may also lengthen as we introduce our Revio and Onso instruments and their 
associated consumables to the market, as our customers may have additional administrative, technical or other requirements 
associated with transitioning to new products and technologies. In anticipation of product orders, we may incur substantial 
costs before the sales cycle is complete and before we receive any customer payments. As a result, if a sale is not completed 

24 

 
or is canceled or delayed, we may have incurred substantial expenses, making it more difficult for us to become profitable or 
otherwise negatively impacting our financial results. Even if our selling efforts are successful, the realization of revenue may 
be  substantially  delayed,  our  ability  to  forecast  our  future  revenue  may  be  more  limited  and  our  revenue  may  fluctuate 
significantly from quarter to quarter and year over year. For more information on the impact of these fluctuations on our 
results and stock price, see “—Our operating results fluctuate from quarter to quarter and year over year, which makes our future 
results difficult to predict and could negatively impact the market price of our common stock,” below. 

Because some of our customers and suppliers are based in China, our business, financial condition and results of operations 
could be adversely affected by the political and economic tensions between the United States and China. 

We are subject to risks associated with political conflicts between the U.S. and China. A significant portion of our revenue is 
generated from China. For example, for the years ended December 31, 2022, 2021, and 2020, one of our customers, who is 
our primary distributor in China, accounted for approximately 12%, 13%, and 14% of our total revenue, respectively. In addition, 
certain components, some of which are critical components, of our products are manufactured in China. These components 
are either sourced directly from companies in China or indirectly from third parties that source from companies in China. 

Consequently, we are subject to significant risks associated with the trading relationship between the U.S. and China, which 
is currently characterized by significant uncertainty. Tariffs imposed by the U.S. and China have increased, and may continue 
to increase, our costs. Additionally, export restrictions imposed by the U.S. may impact our ability to export certain products 
to customers or distributors in China and restrict our ability to use certain integrated circuits in our products, and it is possible 
that  additional  restrictions  will  be  put  in  place  that  could  impact  our  ability  to  provide  our  products  to  customers  or 
distributors in China or source components from China. Moreover, the Chinese government may retaliate against U.S. trade 
restrictions in ways that could impact our business. Given the relatively fluid regulatory environment in China and the United 
States and uncertainty how the U.S. or foreign governments will act with respect to export controls, tariffs, international trade 
agreements and policies, there could be additional import, export, tax, or other regulatory changes in the future. Any such 
changes could directly and adversely impact our financial results and results of operations. For more information, see “—
Enhanced trade tariffs, import restrictions, export restrictions, Chinese regulations or other trade barriers may materially harm 
our business.” 

Other risks could include: 

• 

• 

• 

interruptions to operations in China as a result of the COVID-19 pandemic or other disease outbreaks and natural 
catastrophic  events,  which  have  in  the  past  and  can  result  in  the  future  in  business  closures,  transportation 
restrictions, import and export complications and cause shortages in the supply of raw materials or disruptions in 
manufacturing; 
product supply disruptions and increased costs as a result of heightened exposure to changes in the policies of the 
Chinese government, political unrest or unstable economic conditions in China; and 
the nationalization or other expropriation of private enterprises or intellectual property by the Chinese government. 

Difficulties  in  this  relationship  may  require  us  to  take  actions  adverse  to  our  business  to  comply  with  governmental 
restrictions on business and trade with China. 

In addition, our consumable chips are partly manufactured by a company based in Taiwan. Our supply of consumables chips 
and other critical components may be materially and adversely affected by diplomatic, geopolitical, and other developments 
affecting the relationship between China and Taiwan. Accordingly, there is a risk that current political tensions between China 
and Taiwan may lead to circumstances that negatively affect the availability of such consumable chips and other critical 
components to us, which could limit or prohibit our ability to manufacture consumable chips and other critical components 
or lead to an increase in our supply costs if we cannot find a similar cost alternative supplier, which could materially and 
adversely impact our business, operations, prospects, financial condition and results, and results of operations. 

25 

 
 
 
 
 
 
 
Our operating results fluctuate from quarter to quarter and year over year, which makes our future results difficult to predict 
and could negatively impact the market price of our common stock. 

We operate on a December 31st year-end and believe that there are significant seasonal factors which may cause sales of 
our products, and particularly our sequencing instruments, to vary on a quarterly or yearly basis, contribute to lengthy sales 
cycles  for  our  sequencing  instruments,  and  increase  the  magnitude  of  quarterly  or  annual  fluctuations  in  our  operating 
results. We believe that this seasonality results from a number of factors, including the procurement and budgeting cycles of 
many of our customers, especially government-funded customers, which often coincide with government fiscal year ends. 
For  example,  the  U.S.  government’s  fiscal  year-end  occurs  in  our  third  quarter  and  may  result  in  increased  sales  of  our 
products during this quarter if government-funded customers have unused funds that may be forfeited, or future budgets 
that  may  be  reduced  if  funds  remain  unspent  at  fiscal  year-end.  Furthermore,  Lunar  New  Year  celebrations,  which  occur 
during our first quarter, and may last for a week or longer, resulting in closure of many of our customers’ offices in China and 
across the Asia-Pacific region have caused, and may in the future cause, decreased sales of our consumables during our first 
quarter. These factors have contributed, and in the future may contribute, to substantial fluctuations in our quarterly operating 
results. 

Our operating results during any given period can also be impacted by numerous other factors, including the following: 

•  market acceptance for our products; 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

our ability to attract new customers; 

the length of our sales cycles, as discussed above; 

our ability to achieve economies of scale and other manufacturing efficiencies at the rate we anticipate; 

publications of studies by us, our competitors or third parties; 

the timing and success of new product introductions by us or our competitors or other changes in the competitive 
dynamics of our industry, such as consolidation; 

the amount and timing of our costs and expenses; 

changes in our pricing policies or those of our competitors; 

general economic, industry and market conditions; 

the regulatory environment in which we operate; 

expenses associated with warranty obligations or unforeseen product quality issues; 

the hiring, training, and retention of key employees, including our ability to grow our sales organization; 

litigation or other claims against us for intellectual property infringement or otherwise; 

our ability to obtain additional financing as necessary; 

changes or trends in new technologies and industry standards; and the impact of COVID-19. 

Consequently, it is possible that in some quarters our operating results will fall below the expectations of securities analysts 
or investors. If that happens, the market price of our common stock would likely decrease. These fluctuations, among other 
factors,  also  mean  that  our  operating  results  in  any  particular  period  may  not  be  relied  upon  as  an  indication  of  future 
performance.  Seasonal  or  cyclical  variations  in  our  sales  have  in  the  past,  and  may  in  the  future,  become  more  or  less 
pronounced over time, and have in the past materially affected, and may in the future materially affect, our business, financial 
condition, results of operations, and prospects. 

Our ability to use net operating losses to offset future taxable income may be subject to substantial limitations, and changes 
to U.S. tax laws may cause us to make adjustments to our financial statements. 

Under Section 382 of the Internal Revenue Code, a corporation that undergoes an “ownership change” is subject to limitations 
on its ability to utilize its pre-change net operating losses (“NOLs”) to offset future taxable income. We believe that we have 
had one or more ownership changes, as a result of which our existing NOLs are currently subject to limitation. Future changes 
in  our  stock  ownership  could  result  in  additional  ownership  changes,  including  potentially  material  changes,  under 
Section 382. Consequently, we may not be able to utilize some or all of our NOLs even if we attain profitability.

Our  facilities  in  California  are  located  near  earthquake  faults,  and  the  occurrence  of  an  earthquake  or  other  catastrophic 
disaster could cause damage to our facilities and equipment, which could require us to cease or curtail operations. 

Our facilities in California are located near earthquake fault zones and are vulnerable to damage from earthquakes. We are 
also  vulnerable  to  damage  from  other  types  of  disasters,  including  fire,  floods,  power  loss, communications  failures  and 
similar  events.  If  any  disaster  were  to  occur,  our  ability  to  operate  our  business  at  our  facilities  would  be  seriously,  or 
potentially  completely,  impaired.  In  addition,  the  nature  of  our  activities  could  cause  significant  delays  in  our  research 
programs and commercial activities and make it difficult for us to recover from a disaster. The insurance we maintain may 
not be adequate to cover our losses resulting from disasters or other business interruptions. Accordingly, an earthquake or 
other disaster could materially and adversely harm our ability to conduct business. 

Risks Related to Our Intellectual Property 

Failure to secure patent or other intellectual property protection for our products and improvements to our products may reduce 
our ability to maintain any technological or competitive advantage over our current and potential competitors. 

Our  ability  to  protect  and  enforce  our  intellectual  property  rights  is  uncertain  and  depends  on  complex  legal  and  factual 
questions.  Our  ability  to  establish  or  maintain  a  technological  or  competitive  advantage  over  our  competitors  may  be 
diminished because of these uncertainties. For example: 

•  we  or  our  licensors  might  not  have  been  the  first  to  make  the  inventions  covered  by each  of  our  pending  patent 

applications or issued patents; 

• 

• 

•  we or our licensors might not have been the first to file patent applications for these inventions; 
• 

it is possible that neither our pending patent applications nor the pending patent applications of our licensors will 
result in issued patents; 
the scope of the patent protection we or our licensors obtain may not be sufficiently broad to prevent others from 
practicing  our  technologies,  developing  competing  products,  designing  around  our  patented  technologies  or 
independently developing similar or alternative technologies; 
our and our licensors’ patent applications or patents have been, are and may in the future be, subject to interference, 
opposition or similar administrative proceedings, which could result in those patent applications failing to issue as 
patents, those patents being held invalid or the scope of those patents being substantially reduced; 
our enforcement of patents and proprietary rights in other countries may be problematic or unpredictable; 

• 
•  we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, 
or from selling or importing products made using our inventions in and into the United States or other jurisdictions; 

•  we or our partners may not adequately protect our trade secrets; 
•  we may not develop additional proprietary technologies that are patentable; or 
• 

the  patents  of  others  may  limit  our  freedom  to  operate  and  prevent  us  from  commercializing  our  technology  in 
accordance with our plans. 

The occurrence of any of these events could impair our ability to operate without infringing upon the proprietary rights of 
others or prevent us from establishing or maintaining a competitive advantage over our competitors. 

Variability in intellectual property laws may adversely affect our intellectual property position. 

Intellectual property laws, and patent laws and regulations in particular, have been subject to significant variability either 
through administrative or legislative changes to such laws or regulations or changes or differences in judicial interpretation, 
and it is expected that such variability will continue to occur. Additionally, intellectual property laws and regulations differ by 
country. Variations in the patent laws and regulations or in interpretations of patent laws and regulations in the United States 
and other countries may diminish the value of our intellectual property and may change the impact of third-party intellectual 
property on us. Accordingly, we cannot predict the scope of the patents that may be granted to us with certainty, the extent 
to which we will be able to enforce our patents against third parties or the extent to which third parties may be able to enforce 
their patents against us. 

Some of the intellectual property that is important to our business is owned by other companies or institutions and licensed to 
us, and changes to the rights we have licensed may adversely impact our business. 

We  license  from  third  parties  some  of  the  intellectual  property  that  is  important  to  our  business.  If  the  third  parties  who 
license  intellectual  property  to  us  fail  to  maintain  the  intellectual  property  that  we  have  licensed,  or  lose  rights  to  that 
intellectual property, the rights we have licensed may be reduced or eliminated, which would eliminate barriers against our 
competition.  Termination  of  these  licenses  or  reduction  or  elimination  of  our  licensed  rights  may  result  in  our  having  to 
negotiate  new  or  reinstated  licenses  with  less  favorable  terms,  or  could  subject  us  to  claims  of  intellectual  property 
infringement or contract breach in litigation or other administrative proceedings that could result in damage awards against 
us and injunctions that could prohibit us from selling our products. In addition, some of our licenses from third parties limit 

27 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
the field in which we can use the licensed technology. Therefore, in order for us to use such licensed technology in potential 
future applications that are outside the licensed field of use, we may be required to negotiate new licenses with our licensors 
or expand our rights under our existing licenses. We cannot be certain that we will be able to obtain such licenses or expanded 
rights  on  reasonable  terms  or  at  all.  In  the  event  a  dispute  with  our  licensors  were  to  occur,  our  licensors  may  seek  to 
renegotiate the terms of our licenses, increase the royalty rates that we pay to obtain and maintain those licenses, limit the 
field or scope of the licenses, or terminate the license agreements. In addition, we have limited rights to participate in the 
prosecution and enforcement of the patents and patent applications that we have licensed. If we fail to meet our obligations 
under these licenses,  or if  we  have  a  dispute regarding  the terms  of  the  licenses,  these  third  parties  could  terminate the 
licenses, which could subject us to claims of intellectual property infringement. As a result, we cannot be certain that these 
patents and applications will be prosecuted and enforced in a manner consistent with the best interests of our business. 
Further, because of the rapid pace of technological change in our industry, we may need to rely on key technologies developed 
or licensed by third parties, and we may not be able to obtain licenses and technologies from these third parties at all or on 
reasonable terms. The occurrence of these events may have a material adverse effect on our business, financial condition 
or results of operations. 

The measures that we use to protect the security of and enforce our intellectual property and other proprietary rights may not 
be adequate, which could result in the loss of legal protection for, and thereby diminish the value of, such intellectual property 
and other rights. 

In addition to patents, we also rely upon trademarks, trade secrets, copyrights, and unfair competition laws, as well as license 
agreements and other contractual provisions, to protect our intellectual property and other proprietary rights. Despite these 
measures,  any  of  our  intellectual  property  rights  could  be  challenged,  invalidated,  circumvented,  or  misappropriated.  In 
addition,  we  attempt  to  protect  our  intellectual  property  and  proprietary  information  by  requiring  our  employees  and 
consultants  to  enter  into  confidentiality  and  assignment  of  inventions  agreements,  and  by  entering  into  confidentiality 
agreements with our third-party development, manufacturing, sales, and distribution partners, who may also acquire, develop 
and/or commercialize alternative or competing products or provide services to our competitors. For example, Roche had 
certain access to our trade secrets and other proprietary information pursuant to an agreement we had entered into with 
Roche, subject to the confidentiality provisions thereof (certain of which provisions survive the termination of the agreement); 
however, Roche is developing potentially competing sequencing products. There can be no assurance that our measures 
have provided or will provide adequate protection for our intellectual property and proprietary information. These agreements 
may be breached, and we may not have adequate remedies for any such breach. In addition, our trade secrets and other 
proprietary information may be disclosed to others, or others may gain access to or disclose our trade secrets and other 
proprietary information. Enforcing a claim that a third party illegally obtained and is using our trade secrets is expensive and 
time consuming, and the outcome is unpredictable. Additionally, others may independently develop proprietary information 
and techniques that are substantially equivalent to ours. The occurrence of these events may have a material adverse effect 
on our business, financial condition, or results of operations. 

Our intellectual property may be subject to challenges in the United States or foreign jurisdictions that could adversely affect 
our intellectual property position. 

Our pending, issued and granted U.S. and foreign patents and patent applications have been, are and may in the future be, 
subject to challenges by ONT Ltd., ONT Inc. and Metrichor, Ltd. (“Metrichor” and, together with ONT Ltd. and ONT Inc., “ONT”) 
in addition to other parties asserting prior invention by others or invalidity on various grounds, through proceedings, such 
as interferences, reexaminations, or opposition proceedings. Addressing these challenges to our intellectual property has 
been,  and  any  future  challenges  can  be,  costly  and  distract  management’s  attention  and  resources.  For  example,  we 
previously  incurred  significant  legal  expenses  to  litigate  and  settle  a  complaint  seeking  review  of  a  patent  interference 
decision of the U.S. Patent and Trademark Office. Additionally, ONT previously requested that the U.S. Patent and Trademark 
Office  institute inter  partes reviews  of  certain  patents  that  we  have  asserted  against  ONT  Inc.  and  ONT  Ltd.  in  litigation 
proceedings for patent infringement. While none of the inter  partes reviews requested by ONT were instituted by the U.S. 
Patent and Trademark Office, challenges of this nature before the Patent Trial and Appeal Board (“PTAB”) in the future could 
result  in  determinations  that  our  patents  or  pending  patent  applications  are  unpatentable  to  us,  or  are  invalidated  or 
unenforceable in whole or in part and could require us to expend significant time, funds, and other resources in litigating such 
challenges. Accordingly, adverse rulings in such proceedings could negatively impact the scope of our intellectual property 
protection for our products and technology and could materially and adversely affect our business. Similar mechanisms for 
challenging  the  validity  and  enforceability  of  a  patent  exist  in  foreign  patent  offices  and  courts  and  may  result  in  the 
revocation, cancellation, or amendment of any foreign patents we hold now or in the future. The outcome following legal 
assertions of invalidity and unenforceability is unpredictable, and prior art could render our patents invalid. If a defendant 
were to prevail on a legal assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the 
patent protection on such products. Such a loss of patent protection would have a material adverse impact on our business.

Some of our technology is subject to “march-in” rights by the U.S. government. 

Some  of  our  patented  technology  was  developed  with  U.S.  federal  government  funding.  When  new  technologies 
are developed with  U.S.  government  funding,  the  government  obtains  certain  rights  in  any  resulting  patents,  including  a 
nonexclusive license authorizing the government to use the invention for non-commercial purposes. These rights may permit 
the government to disclose our confidential information to third parties and to exercise “march-in” rights to use or allow third 
parties to use our patented technology. The government can exercise its march-in rights if it determines that such action is 
necessary to (i) achieve practical application of the U.S. government-funded technology, (ii) alleviate health or safety needs, 
(iii) meet requirements of federal regulations, or (iv) give preference to U.S. industry. In addition, U.S. government-funded 
inventions  must  be  reported  to  the  government  and  such  government  funding  must  be  disclosed  in  any  resulting  patent 
applications. Furthermore, our rights in such inventions are subject to government license rights and foreign manufacturing 
restrictions. The U.S. government has generally denied requests to exercise its march-in rights, even to provide access to 
potentially  life-saving  medications;  however,  if  the  U.S.  government  were  to  exercise  its  march-in  rights  to  our  patent 
technologies funded by the U.S. government, particularly for the benefit of one of more of our competitors, that may have a 
material adverse effect on our business. 

We are involved in legal proceedings to enforce our intellectual property rights. 

Our  intellectual  property  rights  involve  complex  factual,  scientific,  and  legal  questions.  We  operate  in  an  industry 
characterized  by  significant  intellectual  property  litigation.  Even  though  we  may  believe  that  we  have  a  valid  patent  on  a 
particular technology, other companies have from time to time taken, and may in the future take, actions that we believe 
violate our patent rights. For example, we were previously involved in legal proceedings with ONT and Harvard University in 
several United States and European jurisdictions. We have in the past received adverse rulings against us with respect to our 
complaint with the United States International Trade Commission for one of these proceedings. Legal actions to enforce our 
patent  rights  have  been,  and  will  continue  to  be,  expensive,  and  may  divert  significant  management  time  and  resources. 
Adverse parties from previous legal actions have brought, and they and others may in the future bring, claims against us 
and/or our intellectual property. Litigation is a significant ongoing expense, recognized in sales, general and administrative 
expense, with an uncertain outcome, and has been, and may in the future be, a material expense for us. Our enforcement 
actions may not be successful, have given rise to legal claims against us and could result in some of our intellectual property 
rights being determined to be invalid or not enforceable. Furthermore, an adverse determination or judgement could lead to 
an award of damages against us, or the issuance of an injunction against us or our products that could prevent us from 
selling any products found to be infringing the intellectual property rights of another party. 

We have been, are currently, and could in the future be, subject to legal proceedings with third parties who may claim that our 
products infringe or misappropriate their intellectual property rights. 

Our  products  are  based  on  complex, rapidly  developing technologies.  We  may  not  be aware  of  issued  or  previously  filed 
patent applications that belong to third parties that mature into issued patents that cover some aspect of our products or 
their use. In addition, because patent litigation is complex and the outcome inherently uncertain, our belief that our products 
do not infringe third-party patents of which we are aware or that such third-party patents are invalid and unenforceable may 
be determined to be incorrect. As a result, third parties have claimed, and may in the future claim, that we infringe their patent 
rights and have filed, and may in the future file lawsuits or engage in other proceedings against us to enforce their patent 
rights. For example, we are involved in legal proceedings for alleged patent infringement and related matters in the United 
States with Personal Genomics of Taiwan, Inc. (“PGI”), Take2 Technologies, Ltd., and the Chinese University of Hong Kong. 
In addition, ONT Ltd. and Harvard University have, in the past, filed claims against us in the High Court of England and Wales 
and the District Court of Mannheim, Germany for patent infringement, and PGI has filed claims against us in the U.S. District 
Court for the District of Delaware and in the Wuhan People’s Court in China. We are aware of other issued patents and patent 
applications owned by third parties that could be construed to read on our products, and related maintenance and support 
services. Although we do not believe that our products or services infringe any valid issued patents, the third-party owners of 
these patents and applications may in the future claim that we infringe their patent rights and file lawsuits against us. In 
addition,  as  we  enter  new  markets,  our  competitors  and  other  third  parties  may  claim  that  our  products  infringe  their 
intellectual property rights as part of a business strategy to impede our successful entry into those markets. Furthermore, 
parties making claims against us may be able to obtain injunctive or other relief, which effectively could block our ability to 
further  develop  or  commercialize  products  or  services  and  could  result  in  the  award  of  substantial  damages  against  us. 
Patent litigation between competitors in our industry is common. Additionally, we have certain obligations to many of our 
customers and suppliers to indemnify and defend them against claims by third parties that our products or their use infringe 
any  intellectual  property  of  these  third  parties.  In  defending  ourselves  against  any  of  these  claims,  we  have  in  the  past 
incurred,  and  could  in  the  future  incur,  to  defend  ourselves  or  our  customers,  substantial  costs,  and  the  attention  of  our 
management and technical personnel could be diverted. For example, we previously incurred significant legal expenses to 
litigate and settle a complaint alleging patent infringement. Even if we have an agreement that indemnifies us against such 
costs, the indemnifying party may be unable to uphold its contractual obligations. To avoid or settle legal claims, it may be 
necessary  or  desirable  in  the  future  to  obtain  licenses  relating  to  one  or  more  products  or  relating  to  current  or  future 

29 

 
technologies, which could negatively affect our gross margins. We may not be able to obtain these licenses on commercially 
reasonable terms, or at all. We may be unable to modify our products so that they do not infringe the intellectual property 
rights of third parties. In some situations, the results of litigation or settlement of claims may require us to cease allegedly 
infringing activities which could prevent us from selling some or all of our products. The occurrence of these events may 
have a material adverse effect on our business, financial condition, or results of operations. 

In addition, in the course of our business, we may from time to time have access or be alleged to have access to confidential 
or proprietary information of others, which, though not patented, may be protected as trade secrets. Others could bring claims 
against us asserting that we improperly used their confidential or proprietary information, or that we misappropriated their 
technologies and incorporated those technologies into our products. A determination that we illegally used the confidential 
or proprietary information or misappropriated technologies of others in our products could result in us paying substantial 
damage awards or being prevented from further developing or selling some or all of our products, which could materially and 
adversely affect our business. 

We have not yet registered some of our trademarks in all of our potential markets, and failure to secure those registrations 
could adversely affect our business. 

Some  of  our  trademark  applications  may  not  be  allowed  for  registration,  and  our  registered  trademarks  may  not  be 
maintained or enforced. In addition, in the U.S. Patent and Trademark Office and in comparable agencies in many foreign 
jurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered 
trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive 
such proceedings. 

Our use of “open source” software could adversely affect our ability to sell our products and subject us to possible litigation. 

A portion of the products or technologies developed and/or distributed by us incorporate “open source” software, and we 
may incorporate open source software into other products or technologies in the future. Some open source software licenses 
require that we disclose the source code for any modifications to such open source software that we make and distribute to 
one  or  more  third  parties,  and  that  we  license  the  source  code  for  such  modifications  to  third  parties,  including  our 
competitors, at no cost. We monitor the use of open source software in our products to avoid uses in a manner that would 
require us to disclose or grant licenses under our source code that we wish to maintain as proprietary; however, there can be 
no assurance that such efforts have been or will be successful. In some circumstances, distribution of our software that 
includes or is linked with open source software could require that we disclose and license some or all of our proprietary 
source code in that software, which could include permitting the use of such software and source code at no cost to the user. 
Open  source  license  terms  are  often  ambiguous  and  there  is  little  legal  precedent  governing  the  interpretation  of  these 
licenses. Successful claims made by the licensors of open source software that we have violated the terms of these licenses 
could result in unanticipated obligations, including being subject to significant damages, being enjoined from distributing 
products that incorporate open source software and being required to make available our proprietary source code pursuant 
to an open source license, which could substantially help our competitors develop products that are similar to or better than 
ours or otherwise materially and adversely affect our business. 

Risks Related to Regulation 

We are, and may become, subject to governmental regulations that may impose burdens on our operations, and the markets 
for our products may be narrowed. 

We are subject, both directly and indirectly, to the adverse impact of government regulation of our operations and markets. 
For example, export of our instruments may be subject to strict regulatory control in a number of jurisdictions. Following 
Russia’s invasion of Ukraine in February 2022, the United States and other countries imposed certain economic sanctions 
and severe export control restrictions against Russia and Belarus as well as certain Russian nationals and individuals and 
entities with ties to Russia, Belarus, and this conflict. These sanctions and restrictions have continued to increase as the 
conflict has further escalated and now cover the export of our products to Russia, and the United States and other countries 
could impose even wider sanctions and export restrictions and take other actions in the future that could further limit our 
ability  to  provide  products  in  certain  locations.  Additionally,  new  restrictions  on  the  ability  to  send  certain  products  and 
technology  related  to  semiconductors,  semiconductor  manufacturing,  and  supercomputing  to  China  without  an  export 
license discussed above impact our ability to provide products to customers or distributors in China. We have expanded and 
are continuing to expand the international jurisdictions into which we supply products, which increases the risks surrounding 
governmental  regulations  relating  to  our  business. The  need  to  or  failure  to  satisfy  export  control  criteria  or  to  obtain 
necessary clearances could delay or prevent shipment of products, which could materially and adversely affect our revenue 
and profitability. Moreover, the life sciences industry, which is expected to continue to be one of the primary markets for our 
technology, has historically been heavily regulated. There are, for example, laws in several jurisdictions restricting research 
in  genetic  engineering,  which  may  narrow  our  markets.  Given  the  evolving  nature  of  this  industry,  legislative  bodies  or 
regulatory authorities may adopt additional regulations that may adversely affect our market opportunities. Additionally, if 

30 

 
ethical and other concerns surrounding the use of genetic information, diagnostics or therapies become widespread, there 
may be less demand for our products. 

Our business is also directly affected by a wide variety of government regulations applicable to business enterprises generally 
and to companies operating in the life science industry in particular. Failure to comply with government regulations or obtain 
or  maintain  necessary  permits  and  licenses  could  result  in  a  variety  of  fines  or  other  censures  or  an  interruption  in  our 
business  operations  which  may  have  a  negative  impact  on  our  ability  to  generate  revenue  and  the  cost  of  operating  our 
business. In addition, changes to laws and government regulations could cause a material adverse effect on our business as 
we will need to adapt our business to comply with such changes. For example, a governmental prohibition on the use of 
human in  vitro diagnostics  or  other  regulations  that  negatively  impact  the  research  and  development  activities  of  our 
customers would adversely impact our commercialization of products on which we have expended significant research and 
development resources, which would in turn have a material adverse impact on our business and prospects. 

Our products could become subject to government regulation as medical devices by the U.S. Food and Drug Administration or 
other domestic and international regulatory agencies even if we do not elect to seek regulatory clearance or approval to market 
our  products  for  diagnostic  purposes,  which  could  increase  our  costs  and  impede  or  delay  our  commercialization  efforts, 
thereby materially and adversely affecting our business and results of operations. 

Our products are currently labeled and promoted as research use only (“RUO”) products, and are not currently designed, or 
intended to be used, for clinical diagnostic tests or as medical devices. However, in the future, certain of our products or 
related applications, such as those that may be developed for clinical uses, could be subject to regulation by the U.S. Food 
and Drug Administration (“FDA”), or the FDA’s regulatory jurisdiction could be expanded to include our products. Also, even 
if  our  products  are  labeled,  promoted,  and  intended  as  RUO,  the  FDA  or  comparable  agencies  of  other  countries  could 
disagree  with  our  conclusion  that  our  products  are  intended  for  research  use  only  or  deem  our  sales,  marketing  and 
promotional  efforts  as  being  inconsistent  with  the  FDA’s  guidance  on  RUO  products.  For  example,  our  customers  may 
independently elect to use our RUO labeled products in their own laboratory developed tests (“LDTs”) for clinical diagnostic 
use, which could subject our products to government regulation, and the regulatory clearance or approval and maintenance 
process for such products may be uncertain, expensive, and time-consuming. Regulatory requirements related to marketing, 
selling,  and  distribution  of  RUO  products  could  change  or  be  uncertain,  even  if  clinical  uses  of  our  RUO  products  by  our 
customers were done without our consent. If the FDA or other regulatory authorities assert that any of our RUO products are 
subject  to regulatory  clearance  or  approval,  our  business,  financial  condition, or  results  of operations  could  be  adversely 
affected. In the event that we fail to obtain and maintain necessary regulatory clearances or approvals for products that we 
develop  for  clinical  uses, or  if  clearances  or  approvals  for  future  products  and  indications  are  delayed or  not  issued,  our 
commercial operations may be materially harmed. Furthermore, even if we are granted regulatory clearances or approvals, 
they may include significant limitations on the indicated uses for the product, which may limit the market for the product. We 
do not have experience in obtaining FDA approvals and no assurance can be given that we will be able to obtain or to maintain 
such approvals. Furthermore, any approvals that we may obtain can be revoked if safety or efficacy problems develop. 

The  FDA  has  historically  exercised  enforcement  discretion  in  not  enforcing  the  medical  device  regulations  against 
laboratories developing and offering LDTs. However, in 2014, the FDA issued two draft guidance documents that set forth 
the FDA’s proposed risk-based framework for regulating LDTs, which are designed, manufactured, and used within a single 
laboratory. The draft guidance documents provide the anticipated details through which the FDA would propose to establish 
an LDT oversight framework, including pre-market review for higher-risk LDTs, such as those that have the same intended 
use as FDA-approved or cleared companion diagnostic tests currently on the market. In 2017, the FDA announced that it 
would not issue final guidance on the oversight of LDTs, and manufacturers of products used for LDTs, but would seek further 
public discussion on an appropriate oversight approach, and give Congress an opportunity to develop a legislative solution. 
More recently, the FDA has issued warning letters to certain genomics labs for illegally marketing genetic tests that claim to 
predict patients’ responses to specific medications, noting that the FDA has not created a legal “carve-out” for LDTs and 
retains  discretion  to  take  action  when  appropriate,  such  as  when  certain  genomic  tests  raise  significant  public  health 
concerns. 

As manufacturers develop more complex diagnostic tests and diagnostic software, the FDA may increase its regulation of 
LDTs. Any future legislative or administrative rule making or oversight of LDTs, if and when finalized, may impact the sales 
of our products and how customers use our products, and may require us to change our business model in order to maintain 
compliance with these laws. We cannot predict how these various efforts will be resolved, how Congress or the FDA will 
regulate  LDTs  in  the  future,  or  how  that  regulatory  system  will  impact  our  business.  Changes  to  the  current  regulatory 
framework, including the imposition of additional or new regulations, including regulation of our products, could arise at any 
time during the development or marketing of our products, which may negatively affect our ability to obtain or maintain FDA 
or comparable regulatory approval of our products, if required. Further, sales of devices for diagnostic purposes may subject 
us to additional healthcare regulation and enforcement by the applicable government agencies. Such laws include, without 
limitation, state and federal anti-kickback or anti-referral laws, healthcare fraud and abuse laws, false claims laws, privacy 

31 

 
and security laws, Physician Payments Sunshine Act and related transparency and manufacturer reporting laws, and other 
laws and regulations applicable to medical device manufacturers. 

Additionally, in 2013, the FDA issued Final Guidance “Distribution of In Vitro Diagnostic Products Labeled for Research Use 
Only.”  The  guidance  emphasizes  that  the  FDA  will  review  the  totality  of  the  circumstances  when  it  comes  to  evaluating 
whether equipment and testing components are properly labeled as RUO. The final guidance states that merely including a 
labeling statement that the product is for research purposes only will not necessarily render the device exempt from the 
FDA’s clearance, approval, and other regulatory requirements if the circumstances surrounding the distribution, marketing 
and promotional practices indicate that the manufacturer knows its products are, or intends for its products to be, used for 
clinical  diagnostic  purposes.  These  circumstances  may  include  written  or  verbal  sales  and  marketing  claims  or  links  to 
articles regarding a product’s performance in clinical applications and a manufacturer’s provision of technical support for 
clinical applications. 

In August 2020, the Department of Health and Human Services ("HHS") announced rescission of guidance and other informal 
issuances of FDA regarding pre-market review of LDT absent notice-and-comment rulemaking, stating that, absent notice-
and-comment rulemaking LDTs are not required to obtain FDA pre-market authorization. In November 2021, HHS under the 
Biden administration issued a statement that withdrew the August 2020 policy announcement stating that HHS does not 
have a policy on LDTs that is separate from FDA’s longstanding approach. 

Legislative  and  administrative  proposals  to  amend  the  FDA's  oversight  of  LDTs  have  been  introduced  in  recent  years, 
including the Verifying Accurate Leading-edge IVCT Development Act of 2021 (the "VALID Act"), which aims to create a new 
category  of  medical  products  separate  from  medical  devices  called  “in  vitro  clinical  tests,”  or  IVCTs,  and  bring  all  such 
products within the scope of the FDA’s oversight. To date, Congress has not passed the VALID Act, but may revisit the VALID 
Act or similar policy riders and enact other FDA programmatic reforms in the future. It is unclear how future legislation by 
federal and state governments and FDA regulation will impact the industry, including our business and that of our customers. 

If the FDA determines our products or related applications should be subject to additional regulation as in vitro diagnostic 
devices  based  upon  customers’  use  of  our  products  for  clinical  diagnostic  or  therapeutic  decision-making  purposes,  our 
ability to market and sell our products could be impeded and our business, prospects, results of operations and financial 
condition may be adversely affected. In addition, the FDA could consider our products to be misbranded or adulterated under 
the Federal Food, Drug, and Cosmetic Act and subject to recall and/or other enforcement action. 

To  the  extent  we  elect  to  label  and  promote  any  of  our  products  as  medical  devices,  we  would  be  required  to  obtain  prior 
approval or clearance by the FDA or comparable foreign regulatory authority, which could take significant time and expense 
and could fail to result in a marketing authorization for the intended uses we believe are commercially attractive. Obtaining 
marketing authorization in one jurisdiction does not mean that we will be successful in obtaining marketing authorization in 
other jurisdictions where we conduct business. 

If we elect to label and market our products for use as, or in the performance of, clinical diagnostics in the United States, 
thereby subjecting them to FDA regulation as medical devices, we would be required to obtain pre-market 510(k) clearance 
or  pre-market  approval  from  the  FDA,  unless  an  exception  applies.  It  is  possible,  in  the  event  we  elect  to  submit 
510(k) applications for certain of our products, that the FDA would take the position that a more burdensome pre-market 
application, such as a PMA or a de novo application is required for some of our products. If such applications were required, 
greater time and investment would be required to obtain FDA approval. Even if the FDA agreed that a 510(k) was appropriate, 
FDA clearance can be expensive and time consuming. It generally takes a significant amount of time to prepare a 510(k), 
including conducting appropriate testing on our products, and several months to years for the FDA to review a submission. 
Notwithstanding the effort and expense, FDA clearance or approval could be denied for some or all of our products for which 
we  choose  to  market  as  a  medical  device  or  a  clinical  diagnostic  device.  Even  if  we  were  to  seek  and  obtain  regulatory 
approval  or  clearance,  it  may  not  be  for  the  intended  uses  we  request  or  that  we  believe  are  important  or  commercially 
attractive. There can be no assurance that future products for which we may seek pre-market clearance or approval will be 
approved or cleared by FDA or a comparable foreign regulatory authority on a timely basis, if at all, nor can there be assurance 
that  labeling  claims  will  be  consistent  with  our  anticipated  claims  or  adequate  to  support  continued  adoption  of  such 
products. Compliance with FDA or comparable foreign regulatory authority regulations will require substantial costs, and 
subject us to heightened scrutiny by regulators and substantial penalties for failure to comply with such requirements or the 
inability to market our products. The lengthy and unpredictable  pre-market clearance or approval process, as well as the 
unpredictability  of  the  results  of  any  required  clinical  studies,  may  result  in  our  failing  to  obtain  regulatory  clearance  or 
approval  to  market  such  products,  which  would  significantly  harm  our  business,  results  of  operations,  reputation,  and 
prospects. 

If we sought and received regulatory clearance or approval for certain of our products, we would be subject to ongoing FDA 
obligations and continued regulatory oversight and review, including the general controls listed above and the FDA’s QSRs 
for our development and manufacturing operations. In addition, we would be required to obtain a new 510(k) clearance before 
we  could  introduce  subsequent  material  modifications  or  improvements  to  such  products.  We  could  also  be  subject  to 

32 

 
additional  FDA  post-marketing  obligations  for  such  products,  any  or  all  of  which  would  increase  our  costs  and  divert 
resources away from other projects. If we sought and received regulatory clearance or approval and are not able to maintain 
regulatory  compliance  with  applicable  laws,  we  could  be  prohibited  from  marketing  our  products  for  use  as,  or  in  the 
performance of, clinical diagnostics and/or could be subject to enforcement actions, including warning letters and adverse 
publicity, fines, injunctions, and civil penalties; recall or seizure of products; operating restrictions; and criminal prosecution. 

Further, if we decide to seek regulatory clearance or approval for certain of our products in countries outside of the United 
States or if a foreign regulatory authority determines that our products are regulated as medical devices, we would be subject 
to extensive medical device laws and regulations outside of the United States. Sales of such products outside the United 
States will likely be subject to foreign regulatory requirements, which can vary greatly from country to country. As a result, 
the time required to obtain clearances or approvals outside the United States may differ from that required to obtain FDA 
clearance or approval and we may not be able to obtain foreign regulatory approvals on a timely basis or at all. In Europe, we 
would need to comply with the Medical Device Regulation 2017/745 and In Vitro Diagnostic Regulation 2017/746, which 
became  effective  May 26,  2017,  with  application  dates  of  May 26,  2021  (postponed  from  2020)  and  May 26,  2022, 
respectively. This will increase the difficulty of regulatory approvals in Europe in the future. In addition, the FDA regulates 
exports of medical devices. The number and scope of these requirements are increasing. Unlike many of the other companies 
offering nucleic acid sequencing equipment or consumables, this is an area where we do not have expertise. We, or our other 
third-party sales and distribution partners, may not be able to obtain regulatory approvals in such countries or may incur 
significant costs in obtaining or maintaining our foreign regulatory approvals. In addition, the export by us of certain of our 
products,  which  have  not  yet  been  cleared  for  domestic  commercial  distribution,  may  be  subject  to  FDA  or  other  export 
restrictions. Failure to comply with these regulatory requirements or obtain and maintain required approvals, clearances and 
certifications could impair our ability to commercialize our products for diagnostic use outside of the United States. Any 
action brought against us for violations of these laws or regulations, even if successfully defended, could cause us to incur 
significant legal expenses and divert our management’s attention from the operation of our business. 

Enhanced trade tariffs, import restrictions, export restrictions, Chinese regulations, or other trade barriers may materially harm 
our business. 

We are continuing to expand our international operations as part of our growth strategy and have experienced an increasing 
concentration of sales in certain regions outside the United States, especially the Asia-Pacific region, as discussed above. 
There is currently significant uncertainty about the future relationship between the United States and various other countries, 
most  significantly  China,  with  respect  to  trade  policies,  treaties,  government  regulations  and  tariffs.  Starting 
in September 2018, the U.S. Trade Representative (the “USTR”) enacted various tariffs of 7.5%, 10%, 15%, and 25% on the 
import of Chinese products, including non-U.S. components and materials that may be used in our products. Additionally, 
China also has imposed tariffs on imports into China from the United States. These tariffs have and could continue to raise 
our costs. Furthermore, tariffs, trade restrictions, or trade barriers that have been, and may in the future be, placed on products 
such as ours by foreign governments, especially China, have raised, and could further raise, amounts paid for some or all of 
our  products,  which  may  result  in  the  loss  of  customers  and  our  business,  and  our  financial  condition  and  results  of 
operations may be harmed. Further tariffs may be imposed that could cover imports of components and materials used in 
our products, or our business may be adversely impacted by retaliatory trade measures taken by China or other countries, 
including restricted access to components or materials used in our products or increased amounts that must be paid for our 
products, which could materially harm our business, financial condition, and results of operations. 

Additionally,  the  U.S.  government  recently  announced  new  controls  restricting  the  ability  to  send  certain  products  and 
technology  related  to  semiconductors,  semiconductor  manufacturing,  and  supercomputing  to  China  without  an  export 
license. These new controls also apply to certain hardware containing these specified integrated circuits. In many cases, 
these licenses are subject to a policy of denial and will not be issued. These controls may impact our ability to export certain 
products to customers or distributors in China and restrict our ability to use certain integrated circuits in our products. The 
U.S.  government  also  recently  added  additional  entities  in  China  to  restricted  party  lists  impacting  the  ability  of  U.S. 
companies  to  provide  items  to  these  entities.  Moreover,  in November 2018,  the  U.S.  Commerce  Department’s  Bureau  of 
Industry  and  Security  (“BIS”)  released  an  advance  notice  of  proposed  rulemaking  to  control  the  export  of  emerging 
technologies.  This  notice  included  “[b]iotechnology,  including  nanobiology;  synthetic  biology;  genomic  and  genetic 
engineering; or neurotech” as possible areas of increased export controls. The Biden Administration has continued to provide 
updated lists of emerging technologies subject to national security consents, and it continues to include biotechnologies 
including  “[g]enome  and  protein  engineering  including  design  tools”  and  “[b]iomanufacturing  and  bioprocessing 
technologies.” Therefore, it is possible that our ability to export our products to customers or distributors in China may be 
further restricted in the future. 

It  is  possible  that  the  Chinese  government  will  retaliate  in  response  to  existing  or  future  U.S.  export  controls  or  trade 
restrictions in ways that could impact our business. It also is possible that additional restrictions will be put in place that 
could impact our ability to provide our products to customers or distributors in China or source components from China. The 
continued  threats  of  tariffs,  trade  restrictions  and  trade  barriers  could  have  a  generally  disruptive  impact  on  the  global 

33 

 
economy and, therefore, negatively impact our sales. Given the relatively fluid regulatory environment in China and the United 
States and uncertainty how the U.S. or foreign governments will act with respect to export controls, tariffs, international trade 
agreements and policies, there could be additional tax or other regulatory changes in the future. Any such changes could 
directly and adversely impact our financial results and results of operations. 

Our  international  business  could  expose  us  to  business,  regulatory,  political,  operational,  financial,  and  economic  risks 
associated with doing business outside of the United States. 

Engaging in international business inherently involves a number of difficulties and risks, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

required  compliance  with  existing  and  changing  foreign  regulatory  requirements  and  laws  that  are  or  may  be 
applicable to our business in the future, such as the European Union’s General Data Protection Regulation (“GDPR”) 
and other data privacy requirements, labor and employment regulations, anti-competition regulations, the U.K. Bribery 
Act  of  2010  and  other  anti-corruption  laws,  regulations  relating  to  the  use  of  certain  hazardous  substances  or 
chemicals  in  commercial  products,  and  require  the  collection,  reuse,  and  recycling  of  waste  from  products  we 
manufacture; 

required compliance with U.S. laws such as the Foreign Corrupt Practices Act, and other U.S. federal laws and trade 
and economic sanctions and other regulations established by the Office of Foreign Asset Control; 

export requirements and import or trade restrictions; 

laws and business practices favoring local companies; 

restrictions on both inbound and outbound cross-border investment; 

foreign currency exchange, longer payment cycles and difficulties in enforcing agreements and collecting receivables 
through certain foreign legal systems; 

changes in social, economic, and political conditions or in laws, regulations and policies governing foreign trade, 
manufacturing, research and development, and investment both domestically as well as in the other countries and 
jurisdictions in which we operate and into which we may sell our products including as a result of the separation of 
the  United  Kingdom  from  the  European  Union  (“Brexit”)  and  ongoing  geopolitical  tensions  related  to  the  political 
uncertainty and military actions associated with the war in Ukraine, resulting sanctions imposed by the U.S. and other 
countries, and retaliatory actions taken by Russia in response to such sanctions; 

potentially adverse tax consequences, tariffs, customs charges, bureaucratic requirements, and other trade barriers; 

difficulties and costs of staffing and managing foreign operations; and 

difficulties  protecting,  maintaining,  enforcing,  or  procuring  intellectual  property  rights  and  defending  against 
intellectual property claims under the law and judicial systems of other countries. 

If one or more of these risks occurs, it could require us to dedicate significant resources to remedy such occurrence, and if 
we are unsuccessful in finding a solution, our financial results will suffer. 

Our operations involve the use of hazardous materials, and we must comply with environmental, health and safety laws, which 
can be expensive and may adversely affect our business, operating results and financial condition. 

Our research and development and manufacturing activities involve the use of hazardous materials, including chemicals and 
biological materials, and some of our products include hazardous materials. Accordingly, we are subject to federal, state, 
local and foreign laws, regulations, and permits relating to environmental, health and safety matters, including, among others, 
those governing  the  use,  storage,  handling,  exposure to  and  disposal  of  hazardous  materials  and  wastes,  the  health  and 
safety of our employees, and the shipment, labeling, collection, recycling, treatment, and disposal of products containing 
hazardous materials. Liability under environmental laws and regulations can be joint and several and without regard to fault 
or negligence. For example, under certain circumstances and under certain environmental laws, we could be held liable for 
costs relating to contamination at our or our predecessors’ past or present facilities and at third-party waste disposal sites. 
We could also be held liable for damages arising out of human exposure to hazardous materials. There can be no assurance 
that violations of environmental, health and safety laws will not occur as a result of human error, accident, equipment failure 
or other causes. The failure to comply with past, present or future laws could result in the imposition of substantial fines and 
penalties, remediation costs, property damage and personal injury claims, investigations, the suspension of production or 
product sales, loss of permits or a cessation of operations. Any of these events could harm our business, operating results, 
and financial condition. We also expect that our operations will be affected by new environmental, health and safety laws and 
regulations on an ongoing basis, or more stringent enforcement of existing laws and regulations. New laws or changes to 
existing laws may result in additional costs and may increase penalties associated with violations or require us to change 
the  content  of  our  products  or  how  we  manufacture  them,  which  could  have  a  material  adverse  effect  on  our  business, 
operating results, and financial condition.

Ethical,  legal,  privacy,  data  protection  and  social  concerns  or  governmental  restrictions  surrounding  the  use  of  genetic 
information could reduce demand for our technology. 

Our products may be used to provide genetic information about humans, agricultural crops and other living organisms. The 
information obtained from our products could be used in a variety of applications which may have underlying ethical, legal, 
privacy, data protection and social concerns, including the genetic engineering or modification of agricultural products or 
testing for genetic predisposition for certain medical conditions. Governmental authorities could, for safety, social or other 
purposes, call for limits on or regulation of the use of genetic testing, and may consider or adopt such regulations or other 
restrictions. Such concerns or governmental restrictions could limit the use of our products or be costly and burdensome to 
comply with, and actual or perceived violations of any such restrictions may lead to the imposition of substantial fines and 
penalties, remediation costs, claims and litigation, regulatory investigations and proceedings, and other liability, any of which 
could have a material adverse effect on our business, financial condition, and results of operations. 

Regulations related to conflict minerals has caused us to incur, and will continue to cause us to incur, additional expenses and 
could limit the supply and increase the costs of certain materials used in the manufacture of our products. 

We are subject to requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 that require 
us to conduct diligence and report on whether or not our products contain conflict minerals. The implementation of these 
requirements  could  adversely  affect  the  sourcing,  availability  and  pricing  of  the  materials  used  in  the  manufacture  of 
components used in our products. Furthermore, the complex nature of our products requires components and materials that 
may be available only from a limited number of sources and, in some cases, from only a single source. We have incurred, and 
will  continue to  incur,  additional  costs  to  comply  with  the  disclosure requirements, including  costs  related  to  conducting 
diligence procedures to determine the sources of conflict minerals that may be used or necessary to the production of our 
products and, if applicable, potential changes to components, processes, or sources of supply as a consequence of such 
verification activities. We may face reputational harm if we determine that certain of our products contain minerals that are 
not determined to be conflict free or if we are unable to alter our processes or sources of supply to avoid using such materials. 
In  such  circumstances,  the  reputational  harm  could  materially  and  adversely  affect  our  business,  financial  condition,  or 
results of operations. 

Risks Related to Owning Our Common Stock 

The price of our common stock has been, is, and may continue to be, highly volatile, and you may be unable to sell your shares 
at or above the price you paid to acquire them. 

The market price of our common stock is highly volatile, and we expect it to continue to be volatile for the foreseeable future 
in response to many risk factors listed in this section, and others beyond our control, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

actual or anticipated fluctuations in our financial condition and operating results; 

announcements of new products, technological innovations or strategic partnerships by us or our competitors; 

announcements by us, our customers, partners, or suppliers relating directly or indirectly to our products, services or 
technologies; 

overall conditions in our industry and market; 

addition or loss of significant customers; 

changes in laws or regulations applicable to our products; 

actual or anticipated changes in our growth rate relative to our competitors; 

announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, capital 
commitments or achievement of significant milestones; 

additions or departures of key personnel; 

competition from existing products or new products that may emerge; 

issuance of new or updated research or reports by securities analysts; 

fluctuations in the valuation of companies perceived by investors to be comparable to us; 

disputes  or  other  developments  related  to  proprietary  rights,  including  patents,  litigation  matters  or  our  ability  to 
obtain intellectual property protection for our technologies; 

announcement or expectation of additional financing efforts; 

sales of our common stock by us or our stockholders; 

35 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

• 

• 

• 

stock price and volume fluctuations attributable to inconsistent trading volume levels of our shares; 

reports, guidance and ratings issued by securities or industry analysts; 

operating results below the expectations of securities analysts or investors; and 

general economic and market conditions, which could be impacted by various events including COVID-19 or interest 
rate  fluctuations,  increases  in  fuel  prices,  foreign  currency  fluctuations,  international  tariffs,  acts  of  terrorism, 
hostilities  or  the  perception  that  hostilities  may  be  imminent,  military  conflict  and  acts  of  war,  including  further 
political  uncertainty  and  military  actions  associated  with  the  war  in  Ukraine  and  the  related  response,  including 
sanctions or other restrictive actions, by the United States and/or other countries. 

If any of the forgoing occurs, it would cause our stock price or trading volume to decline. Stock markets in general and the 
market  for  companies  in  our  industry  in  particular  have  experienced  price  and  volume  fluctuations,  which  have  been 
exacerbated by the COVID-19 pandemic, and current macroeconomic trends and geopolitical events, and have affected and 
continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated 
or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well 
as  general  economic,  political  and  market  conditions  such  as  recessions,  interest  rate  changes  or  international  currency 
fluctuations, may negatively impact the market price of our common stock. You may not realize any return on your investment 
in us and may lose some or all of your investment. In the past, companies that have experienced volatility in the market price 
of their stock have been subject to securities class action litigation. We have been a party to this type of litigation in the past 
and may be the target of this type of litigation again in the future. Securities litigation against us could result in substantial 
costs and divert our management’s attention from other business concerns, which could seriously harm our business. 

Sales of substantial amounts of our common stock in the public markets, or the perception that such sales might occur, could 
reduce the market price that our common stock might otherwise attain and may dilute your voting power and your ownership 
interest in us. 

Sales of a substantial number of shares of our common stock in the public market, or the perception that such sales could 
occur, could adversely affect the market price of our common stock and may make it more difficult for existing stockholders 
to sell their common stock at a time and price that they deem appropriate and may dilute their voting power and ownership 
interest in us. 

In addition, if our existing stockholders sell, or indicate an intent to sell, a large number of shares of our common stock in the 
public market, it could cause our stock price to fall. We may also issue shares of common stock or securities convertible into 
our common stock in connection with a financing, acquisition, our equity incentive plans, or otherwise. Any such issuances 
would result in dilution to our existing stockholders and the market price of our common stock may be adversely affected. 

In  September 2021,  in  connection  with  the  closing  of  the  Omniome  Merger,  we  completed  a  private  placement  of  an 
aggregate  of  11,214,953  shares  of  our  common  stock,  at  a  price  of  $26.75  per  share,  for  aggregate  gross  proceeds  of 
approximately $300 million (the “Private Placement”) and registered the Private Placement shares for resale on a registration 
statement  on  Form S-3.  The  Private  Placement  Investors  may  sell  any  or  all  of  their  shares  pursuant  to  the  registration 
statement from time to time. 

On January 27, 2023, we issued and sold an aggregate of 20,125,000 shares of our common stock at a purchase price of 
$10.00 per share pursuant to an automatic shelf registration statement filed on  Form S-3 (File No. 333-249999) with the 
Securities and Exchange Commission, resulting in aggregate gross proceeds of approximately $201.3 million. The investors 
may sell any or all of their shares from time to time. 

Concentration of ownership by our principal stockholders may result in control by such stockholders of the composition of our 
board of directors. 

Our existing principal stockholders, executive officers, directors, and their affiliates beneficially own a significant number of 
our outstanding shares of common stock. In addition, such parties may acquire additional control by purchasing stock that 
we issue in connection with our future fundraising efforts. These parties may now and in the future be able to exercise a 
significant level of control over all matters requiring stockholder approval, including the election of directors. This control 
could have the effect of delaying or preventing a change of control of our company or changes in management and will make 
the approval of certain transactions difficult or impossible without the support of these stockholders. 

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be 
beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current 
management and limit the market price of our common stock. 

Provisions in our amended and restated certificate of incorporation and amended and restated bylaws may have the effect 
of  delaying  or  preventing  a  change  of  control  or  changes  in  our  management.  Our  amended  and  restated  certificate  of 
incorporation and amended and restated bylaws include provisions that: 

36 

 
 
 
 
 
 
 
 
• 

• 

• 

• 

• 

• 

• 

authorize  our  board  of  directors  to  issue,  without  further  action  by  the  stockholders,  up  to  50,000,000  shares  of 
undesignated preferred stock and up to approximately 1,000,000,000 shares of authorized but unissued shares of 
common stock; 

require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not 
by written consent; 

specify that special meetings of our stockholders can be called only by our board of directors, the Chair of the Board, 
the Chief Executive Officer or the President; 

establish  advance  notice  procedures  for  stockholder  approvals  to  be  brought  before  an  annual  meeting  of  our 
stockholders, including proposed nominations of persons for election to our board of directors; 

establish that our board of directors is divided into three classes, Class I, Class II and Class III, with each class serving 
staggered terms; 

provide that our directors may be removed only for cause; and 

provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even 
though less than a quorum. 

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management 
by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing 
the members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions 
of Section 203 of the Delaware General Corporation Law, which limits the ability of stockholders owning in excess of 15% of 
our outstanding voting stock to merge or combine with us. 

Our amended and restated bylaws designate a state or federal court located within the State of Delaware as the exclusive forum 
for  certain  stockholder  litigation  matters,  and  also  provide  that  the  federal  district  courts  will  be  the  exclusive  forum  for 
resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, each of which could 
limit  our  stockholders’  ability  to  choose  the  judicial  forum  for  disputes  with  us  or  our  directors,  officers,  stockholders,  or 
employees. 

Our amended and restated bylaws provide that unless we consent in writing to the selection of an alternative forum, the Court 
of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another State court in Delaware 
or the federal district court for the District of Delaware) will, to the fullest extent permitted by law, be the sole and exclusive 
forum  for:  (i) any  derivative  action  or  proceeding  brought  on  our  behalf
  (ii) any  action  asserting  a  claim  of  breach  of  a 
fiduciary  duty  owed  by  any  of  our  current  or  former  directors,  stockholders,  officers,  or  other  employees  to  us  or  our 
stockholders
 (iii) any action arising pursuant to any provision of the Delaware General Corporation Law; (iv) any action to 
interpret, apply, enforce or determine the validity of our amended and restated certificate of incorporation or our amended 
and  restated  bylaws
  or  (v) any  action  asserting  a  claim  governed  by  the  internal  affairs  doctrine,  except  as  to  each  of 
(i) through (v) above, for any claim as to which such court determines that there is an indispensable party not subject to the 
jurisdiction of such court. 

;

;

;

Section 22  of  the  Securities  Act  creates  concurrent  jurisdiction  for  federal  and  state  courts  over  all  such  Securities  Act 
actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate 
claims  in  multiple  jurisdictions  and  the  threat  of  inconsistent  or  contrary  rulings  by  different  courts,  among  other 
considerations,  our  amended  and  restated  bylaws  also  provide  that,  unless  we  consent  in  writing  to  the  selection  of  an 
alternative forum, the federal district courts of the United States of America will be the exclusive forum for resolving any 
complaint asserting a cause of action arising under the Securities Act including, without limitation and for the avoidance of 
doubt, any auditor, underwriter, expert, control person or other defendant. 

Any person or entity purchasing, holding or otherwise acquiring any interest in any of our securities shall be deemed to have 
notice of and consented to the foregoing bylaw provisions. Although we believe these exclusive forum provisions benefit us 
by providing increased consistency in the application of Delaware law and federal securities laws in the types of lawsuits to 
which each applies, the exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum of its 
choosing  for  disputes  with  us  or  any  of  our  directors,  stockholders,  officers  or  other  employees,  which  may  discourage 
lawsuits  with  respect  to  such  claims  against  us  and  our  current  and  former  directors,  stockholders,  officers  or  other 
employees. In addition, a stockholder that is unable to bring a claim in the judicial forum of its choosing may be required to 
incur additional costs in the pursuit of actions which are subject to the exclusive forum provisions described above. Our 
stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations 
thereunder as a result of our exclusive forum provisions. Further, in the event a court finds either exclusive forum provision 
contained  in  our  bylaws  to  be  unenforceable  or  inapplicable  in  an  action,  we  may  incur  additional  costs  associated  with 
resolving such action in other jurisdictions, which could harm our results of operations. 

37 

 
 
 
 
 
 
 
 
Our  large  number  of  authorized  but  unissued  shares  of  common  stock  may  potentially  dilute  existing  stockholders’ 
stockholdings. 

We have a significant number of authorized but unissued shares of common stock. Our board of directors may issue shares 
of common stock from this authorized but unissued pool from time to time without stockholder approval, resulting in the 
dilution of our existing stockholders. 

We do not intend to pay dividends for the foreseeable future. 

We have never declared or paid any dividends on our common stock and do not intend to pay any dividends in the foreseeable 
future. We anticipate that we will retain all of our future earnings for use in the operation of our business and for general 
corporate  purposes.  Any  determination  to  pay  dividends  in  the  future  will  be  at  the  discretion  of  our  board  of  directors. 
Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only 
way to realize any future gains on their investments. 

Risks Related to Our Notes 

We may not have the ability to raise the funds necessary to settle conversions of the Notes in cash or to repurchase the Notes 
upon  a  fundamental  change,  and  our  future  debt  may  contain  limitations  on  our  ability  to  pay  cash  upon  conversion  or 
repurchase of the Notes. 

In February 2021, we issued $900.0 million in aggregate principal amount of 1.50% Convertible Senior Notes due 2028, which 
we refer to as the Notes. The Notes will mature on February 15, 2028, subject to earlier conversion, redemption or repurchase, 
including upon a fundamental change. Holders of the Notes will have the right to require us to repurchase all or a portion of 
their Notes upon the occurrence of a fundamental change before the maturity date at a repurchase price equal to 100% of 
the principal amount of the Notes to be repurchased, plus unpaid interest to, but excluding, the maturity date. In addition, 
upon conversion of the Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other 
than paying cash in lieu of delivering any fractional share), we will be required to settle a portion or all of our conversion 
obligation in cash in respect of the Notes being converted. Moreover, we will be required to repay the Notes in cash at their 
maturity unless earlier converted, redeemed, or repurchased. However, we may not have enough available cash or be able to 
obtain financing at the time we are required to make repurchases of Notes surrendered therefor or pay cash with respect to 
Notes being converted or at their maturity. 

In addition, our ability to repurchase Notes or to pay cash upon conversions of Notes or at their maturity may be limited by 
law, regulatory authority or agreements governing our future indebtedness. Our failure to repurchase Notes at a time when 
the repurchase is required by the indenture or to pay cash upon conversions of Notes or at their maturity as required by the 
indenture would constitute a default under the indenture. A default under the indenture or the fundamental change itself could 
also  lead  to  a  default  under  agreements  governing  our  future  indebtedness.  Moreover,  the  occurrence  of  a  fundamental 
change under the indenture could constitute an event of default under any such agreement. If the payment of the related 
indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay 
the indebtedness or to pay cash amounts due upon conversion, upon required repurchase or at maturity of the Notes. 

If the Notes are converted, it may adversely affect our financial condition and operating results. 

Holders of the Notes are entitled to convert their Notes at any time at their option. If one or more holders elect to convert 
their Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than 
paying  cash  in  lieu  of  delivering  any  fractional  share),  we  would  be  required  to  settle  a  portion  or  all  of  our  conversion 
obligation in cash, which could adversely affect our liquidity. 

General Risk Factors 

Unfavorable  global  economic  or  political  conditions  could  adversely  affect  our  business,  financial  condition  or  results  of 
operations. 

General conditions in the global economy and in the global financial markets could adversely affect our results of operations, 
including the potential effects from the ongoing COVID-19 pandemic as discussed above, and the overall demand for nucleic 
acid  sequencing  products  may  be  particularly  vulnerable  to  unfavorable  economic  conditions.  A  global  financial  crisis, 
inflation or a global or regional political disruption, as well as acts of terrorism, hostilities, military conflict and acts of war, 
including any further political uncertainty and military actions associated with the war in Ukraine and the related response, 
could  cause  extreme  volatility  in  the  capital  and  credit  markets.  A  severe  or  prolonged  economic  downturn  or  political 
disruption could result in a variety of risks to our business, including weakened demand for our products and our ability to 
raise additional capital when needed on acceptable terms, if at all. A weak or declining economy or political disruption could 
also strain our manufacturers or suppliers, possibly resulting in supply disruption, or cause our customers to delay making 
payments for our product and services. An impairment in value of our tangible or intangible assets could also be recorded as 
a result of weaker economic conditions. Any of the foregoing could harm our business and we cannot anticipate all of the 
ways in which the political or economic climate and financial market conditions could adversely impact our business. 

38 

 
Delivery of our products could be delayed or disrupted by factors beyond our control, and we could lose customers as a result. 

We rely on third-party carriers for the timely delivery of our products. As a result, we are subject to carrier disruptions and 
increased costs that are beyond our control. Any failure to deliver products to our customers in a safe and timely manner 
may damage our reputation and brand and could cause us to lose customers. If our relationship with any of these third-party 
carriers is terminated or impaired or if any of these carriers are unable to deliver our products, the delivery of our products by 
our customers may be delayed, which could harm our business and financial results. The failure to deliver our products in a 
safe  and  timely  manner  may  harm  our  relationship  with  our  customers,  increase  our  costs  and  otherwise  disrupt  our 
operations. 

Doing business internationally creates operational and financial risks for our business. 

We  currently  conduct  operations  in  various  countries  and  jurisdictions,  and  continue  to  expand  to  new  international 
jurisdictions as part of our growth strategy and have experienced an increasing concentration of sales in certain regions 
outside the U.S. We sell directly and through distribution partners throughout Europe, the Asia-Pacific region, Mexico, Brazil, 
and South Africa and have a significant portion of our sales and customer support personnel in Europe and the Asia-Pacific 
region.  As  a  result, we  or  our  distribution  partners  may  be  subject  to  additional  regulations  and  increased  diversion  of 
management time and efforts. Conducting and launching operations on an international scale requires close coordination of 
activities  across  multiple  jurisdictions  and  time  zones  and  consumes  significant  management  resources. If  we  fail  to 
coordinate  and  manage  these  activities  effectively,  our  business,  financial  condition  or  results  of  operations  could  be 
materially and adversely affected and failure to comply with laws and regulations applicable to business operations in foreign 
jurisdictions may also subject us to significant liabilities and other penalties. International operations entail a variety of other 
risks, including, without limitation: 

• 

• 

• 

• 

• 

• 

• 

limits to travel as a result of the COVID-19 pandemic or other epidemics; 

challenges in staffing and managing foreign operations; 

potentially  longer  sales  cycles  and  more  time  required  to  engage  and  educate  customers  on  the  benefits  of  our 
platform outside of the United States; 

the potential need for localized software and documentation; 

reduced protection for intellectual property rights in some countries and practical difficulties of enforcing intellectual 
property and contract rights abroad; 

defending against intellectual property claims in other countries; 

restrictions on both inbound and outbound cross-border investment, including enhanced oversight by the Committee 
on Foreign Investment in the United States (“CFIUS”) and substantial restrictions on investment from China; 

•  U.S. and foreign government trade restrictions, including those which may impose restrictions on the importation, 
exportation,  re-exportation,  sale,  shipment  or  other  transfer  of  programming,  technology,  components,  and/or 
services to foreign persons; 

• 

• 

• 

• 

• 

• 

• 

• 

• 

changes  in  diplomatic  and  trade  relationships,  including  new  tariffs,  trade  protection  measures,  import  or  export 
licensing requirements, trade embargoes, sanctions, and other trade barriers; 

tariffs imposed by the U.S. on goods from other countries and tariffs imposed by other countries on U.S. goods, 
including the tariffs by the U.S. government on various imports from China, Canada, Mexico, and the European Union 
(“E.U.”) and by the governments of these jurisdictions on certain U.S. goods, and any other possible tariffs that may 
be imposed on products such as ours, the scope and duration of which, if implemented, remains uncertain; 

deterioration of political relations between the U.S. and Russia, China, Japan, Korea, Canada, the United Kingdom 
(“U.K.”), and the E.U., which could have a material adverse effect on our sales and operations in these countries; 

changes in social, political, and economic conditions or in laws, regulations and policies governing foreign trade, 
manufacturing, development, and investment both domestically as well as in the other countries and jurisdictions 
into which we sell our products, including as a result of the withdrawal of the U.K. from the E.U.; 

difficulties in obtaining  export licenses or in overcoming other trade barriers and restrictions resulting in delivery 
delays; 

fluctuations in currency exchange rates and the related effect on our results of operations; 

increased financial accounting and reporting burdens and complexities; 

disruptions to global trade due to disease outbreaks or conflicts; 

potential increases on tariffs or restrictions on trade generally; and 

39 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• 

significant taxes or other burdens of complying with a variety of foreign laws and regulations, including laws and 
regulations relating to privacy and data protection such as the E.U. General Data Protection Regulation which took 
effect in the E.U. in 2018. 

In conducting our international operations, we are subject to U.S. laws relating to our international activities, such as the 
Foreign Corrupt Practices Act of 1977, as well as foreign laws relating to our activities in other countries, such as the United 
Kingdom Bribery Act of 2010. Additionally, the inclusion of one of our foreign customers on any U.S. Government sanctioned 
persons list, including but not limited to the U.S. Department of Commerce’s List of Denied Persons and the U.S. Department 
of Treasury’s List of Specially Designated Nationals and Blocked Persons List, could be material to our earnings. Failure to 
comply  with  these  laws  may  subject  us  to  claims  or  financial  and/or  other  penalties  in  the  United  States  and/or  foreign 
countries  that  could  materially  and  adversely  impact  our  operations  or  financial  condition.  These  risks  have  become 
increasingly prevalent as we have expanded our sales into countries that are generally recognized as having a higher risk of 
corruption. 

We  face  risks  related  to  the  current  global  economic  environment,  which  could  delay  or  prevent  our  customers  from 
purchasing our products, which could in turn harm our business, financial condition, and results of operations. The state of 
the global economy continues to be uncertain. The current global economic conditions and uncertain credit markets and 
concerns regarding the availability of credit pose a risk that could impact customer demand for our products, as well as our 
ability  to  manage  normal  commercial  relationships  with  our  customers,  suppliers,  and  creditors,  including  financial 
institutions. If the current global economic environment deteriorates, our business could be negatively affected. 

Moreover, changes in the value of the relevant currencies may affect the cost of certain items required in our operations. 
Changes in currency exchange rates may also affect the relative prices at which we are able to sell products in the same 
market. Our revenue from international customers may be negatively impacted as increases in the U.S. dollar relative to our 
international customers’ local currencies could make our products more expensive, impacting our ability to compete or as a 
result of financial or other instability in such locations which could result in decreased sales of our products. Our costs of 
materials  from  international  suppliers  may  also  increase  as  the  value  of  the  U.S.  dollar  decreases  relative  to  their  local 
currency. Foreign policies and actions regarding currency valuation could result in actions by the United States and other 
countries to offset the effects of such fluctuations. Such actions may materially and adversely impact our financial condition 
and results of operations. 

Violations of complex foreign and U.S. laws and regulations could result in fines and penalties, criminal sanctions against us, 
our  officers,  or  our  employees,  prohibitions  on  the  conduct  of  our  business  and  on  our  ability  to  offer  our  products  and 
services in one or more countries, and could also materially affect our brand, our international growth efforts, our ability to 
attract and retain employees, our business, and our operating results. Even if we implement policies or procedures designed 
to  ensure  compliance  with  these  laws  and  regulations,  there  can  be  no  assurance  that  our  distribution  partners,  our 
employees, contractors, or agents will not violate our policies and subject us to potential claims or penalties. 

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely 
basis could be impaired, which would adversely affect our business and our stock price. 

Ensuring  that  we  have  adequate  internal  financial  and  accounting  controls  and  procedures  in  place  to  produce  accurate 
financial statements on a timely basis is a costly and time-consuming effort that needs to be evaluated frequently. We may 
in  the  future  discover  areas  of  our  internal  financial  and  accounting  controls  and  procedures  that  need  improvement. 
Operating as a public company requires sufficient resources within the accounting and finance functions in order to produce 
timely financial information, ensure the level of segregation of duties, and maintain adequate internal control over financial 
reporting customary for a U.S. public company. 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide 
reasonable  assurance  regarding  the  reliability  of  our  financial  reporting  and  the  preparation  of  financial  statements  for 
external purposes in accordance with U.S. GAAP. Our management does not expect that our internal control over financial 
reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can 
provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent 
limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error 
or fraud will not occur or that all control issues and instances of fraud, if any, within our company will have been detected. 

Pursuant to Section 404 of the Sarbanes-Oxley Act, we perform periodic evaluations of our internal control over financial 
reporting. While we have in the past performed this evaluation and concluded that our internal control over financial reporting 
was operating effectively, there can be no assurance that in the future material weaknesses or significant deficiencies will 
not exist or otherwise be discovered. In addition, if we are unable to produce accurate financial statements on a timely basis, 
investors  could  lose  confidence  in  the  reliability  of  our  financial  statements,  which  could  cause  the  market  price  of  our 
common stock to decline and make it more difficult for us to finance our operations and growth.

Our business could be negatively impacted by changes in the United States political environment. 

There is significant ongoing uncertainty with respect to potential legislation, regulation and government policy at the federal 
level, as well as the state and local levels. Any such changes could significantly impact our business as well as the markets 
in which we compete. Specific legislative and regulatory proposals discussed during election campaigns and more recently 
that might materially impact us include, but are not limited to, changes to spending priorities and potential reductions in 
research funding. Uncertainty about U.S. government funding has posed, and may continue to pose, a risk as customers may 
choose to postpone or reduce spending in response to actual or anticipated restraints on funding. To the extent changes in 
the political environment have a negative impact on us or on our markets, our business, results of operation and financial 
condition could be materially and adversely impacted in the future. 

Disruption  of  critical  information  technology  systems  or  material  breaches  in  the  security  of  our  systems  could  harm  our 
business, customer relations and financial condition. 

Information  technology  (“IT”)  helps  us  to  operate  efficiently,  interface  with  customers,  maintain  financial  accuracy  and 
efficiently and accurately produce our financial statements. IT systems are used extensively in virtually all aspects of our 
business, including sales forecast, order fulfillment and billing, customer service, logistics, and management of data from 
running samples on our products. Our success depends, in part, on the continued and uninterrupted performance of our IT 
systems. Our IT systems may be vulnerable to damage from a variety of sources, including telecommunications or network 
failures,  power  loss,  natural  disasters,  human  acts,  computer  viruses,  ransomware,  computer  denial-of-service  attacks, 
unauthorized access to customer or employee data or company trade secrets, and other attempts to harm our systems. 
Furthermore, there may be a heightened risk of potential cybersecurity incidents and security breaches to which we could be 
vulnerable by state-sponsored or affiliated actors or others in connection with the political uncertainty and military actions 
associated  with  the  war  in  Ukraine.  Certain  of  our  systems  are  not  redundant,  and  our  disaster  recovery  planning  is  not 
sufficient  for  every  eventuality.  Despite  any  precautions  we  may  take,  such  problems  could  result  in,  among  other 
consequences, disruption of our operations, which could harm our reputation and financial results. 

If we do not allocate and effectively manage the resources necessary to build and sustain the proper IT infrastructure, we 
could be subject to transaction errors, processing inefficiencies, loss of customers, business disruptions or loss of or damage 
to intellectual property. If our data management systems do not effectively collect, store, process and report relevant data 
for the operation of our business, whether due to equipment malfunction or constraints, software deficiencies or human error, 
our ability to effectively plan, forecast and execute our business plan and comply with applicable laws and regulations will be 
impaired, perhaps materially. Any such impairment could materially and adversely affect our reputation, financial condition, 
results of operations, cash flows and the timeliness with which we report our internal and external operating results. 

Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our 
business and reputation to suffer. 

In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary 
business information and that of our customers, suppliers and business partners, and personally identifiable information of 
our  customers  and  employees,  in  our  data  centers  and  on  our  networks.  The  secure  processing,  maintenance  and 
transmission of this information is critical to our operations. Despite our security measures, our IT infrastructure may be 
vulnerable to attacks by hackers, computer viruses, malicious codes, ransomware, unauthorized access attempts, and cyber- 
or phishing-attacks, or breached or otherwise disrupted due to employee error, malfeasance, faulty password management 
or other disruptions. Third parties may attempt to fraudulently induce employees or other persons into disclosing usernames, 
passwords or other sensitive information, which may in turn be used to access our IT systems, commit identity theft or carry 
out other unauthorized or illegal activities. Any such breach or incident could compromise our systems and networks and the 
information stored or otherwise processed there could be accessed, publicly disclosed, lost, stolen or otherwise processed 
in an unauthorized manner. We engage third-party vendors and service providers to store and otherwise process some of our 
data, including sensitive and personal information. Our vendors and service providers may also be the targets of the risks 
described  above,  including  cyberattacks,  malicious  software,  ransomware,  phishing  schemes,  and  fraud.  Our  ability  to 
monitor our vendors and service providers’ data security is limited, and, in any event, third parties may be able to circumvent 
those security measures, resulting in the unauthorized access to, misuse, disclosure, loss or destruction of our data, including 
sensitive and personal information, and disruption of our or third-party service providers’ systems. We and our third-party 
service  providers  may  face  difficulties  in  identifying,  or  promptly  responding  to,  potential  security  breaches  and  other 
instances of unauthorized access to, or disclosure or other loss or unavailability of, information. Any hacking or other attack 
on our or our third-party service providers’ or vendors’ systems, and any unauthorized access to, or disclosure or other loss 
of, information suffered by us or our third-party service providers or vendors, or the perception that any of these have occurred, 
could result in legal claims or proceedings, loss of intellectual property, liability under laws that protect the privacy of personal 
information,  negative  publicity,  disruption  of  our  operations  and  damage  to  our  reputation,  which  could  divert  our 
management’s attention from the operation of our business and materially and adversely affect our business, revenues and 
competitive position. Moreover, we may need to increase our efforts to train our personnel to detect and defend against 
cyber- or phishing-attacks, which are becoming more sophisticated and frequent, and we may need to implement additional 

41 

 
protective measures to reduce the risk of potential security breaches and security incidents, which could cause us to incur 
significant additional expenses. Retaliatory acts by Russia in response to Western sanctions or otherwise in connection with 
the war in Ukraine could include cyber attacks that could disrupt the economy generally or that may either directly or indirectly 
impact our operations specifically. 

In  addition,  our  insurance  may  be  insufficient  to  cover  our  losses  resulting  from  cyber-attacks,  breaches,  or  other 
interruptions, and any incidents may result in loss of, or increased costs of, such insurance. The successful assertion of one 
or  more  large  claims  against  us  that  exceed  available  insurance  coverage,  the  occurrence  of  changes  in  our  insurance 
policies,  including  premium  increases  or  the  imposition  of  large  deductible  or  co-insurance  requirements,  or  denials  of 
coverage, could have a material adverse effect on our business, including our financial condition, results of operations and 
reputation. 

We are currently subject to, and may in the future become subject to additional, U.S. federal and state laws and regulations 
imposing obligations on how we collect, store and process personal information. Our actual or perceived failure to comply with 
such obligations could harm our business. Ensuring compliance with such laws could also impair our efforts to maintain and 
expand our future customer base, and thereby decrease our revenue. 

In the ordinary course of our business, we currently, and in the future will, collect, store, transfer, use or process sensitive 
data,  including  personally  identifiable  information  of  employees,  and  intellectual  property  and  proprietary  business 
information  owned  or controlled  by  ourselves  and  other  parties.  The  secure  processing,  storage,  maintenance,  and 
transmission  of  this  critical  information  are  vital  to  our  operations  and  business  strategy.  We  are,  and  may  increasingly 
become, subject to various laws and regulations, as well as contractual obligations, relating to data privacy and security in 
the jurisdictions in which we operate. The regulatory environment related to data privacy and security is increasingly rigorous, 
with new and constantly changing requirements applicable to our business, and enforcement practices are likely to remain 
uncertain for the foreseeable future. These laws and regulations may be interpreted and applied differently over time and 
from jurisdiction to jurisdiction, and it is possible that they will be interpreted and applied in ways that may have a material 
adverse effect on our business, financial condition, results of operations and prospects. 

In  the  United  States,  various  federal  and  state  regulators,  including  governmental  agencies  like  the  Consumer  Financial 
Protection Bureau and  the Federal  Trade  Commission,  have  adopted,  or  are  considering  adopting,  laws  and  regulations 
concerning personal information and data security. Certain state laws may be more stringent or broader in scope, or offer 
greater individual rights, with respect to personal information than federal, international or other state laws, and such laws 
may differ from each other, all of which may complicate compliance efforts. For example, the California Consumer Privacy 
Act (“CCPA”), which increases privacy rights for California residents and imposes obligations on companies that process 
their personal information, came into effect on January 1, 2020. Among other things, the CCPA requires covered companies 
to provide new disclosures to California consumers and provide such consumers new data protection and privacy rights, 
including the ability to opt-out of certain sales of personal information. The CCPA provides for civil penalties for violations, 
as well as a private right of action for certain data breaches that result in the loss of personal information. This private right 
of action may increase the likelihood of, and risks associated with, data breach litigation. In November 2020, California also 
passed the California Privacy Rights Act, or (“CPRA”), which significantly expands the CCPA as of January 1, 2023, including 
by  introducing  additional  obligations  such  as  data  minimization  and  storage  limitations  and  granting  additional  rights  to 
consumers, among others. The enactment of the CCPA has prompted similar legislative developments in other states, such 
as  Virginia,  which  in  March 2021  enacted  a  Consumer  Data  Protection  Act  that  is  effective  as  of  January 1,  2023,  and 
Colorado, which in June 2021 enacted a Colorado Privacy Act that is effective as of July 1, 2023, Utah, which in March 2022 
enacted a Utah Consumer Privacy Act that is effective as of July 1, 2023, and Connecticut, which in May 2022 enacted a 
similar law, An Act Concerning Personal Data Privacy and Online Monitoring, that is effective as of July 1, 2023. Similar laws 
are being considered by other state legislatures. In addition, laws in all 50 U.S. states require businesses to provide notice to 
consumers whose personal information has been disclosed as a result of a data breach. State laws are changing rapidly and 
there is discussion in the U.S. Congress of a new comprehensive federal data privacy law to which we would become subject 
if it is enacted. These and future laws and regulations may increase our compliance costs and potential liability. 

Furthermore, regulations promulgated pursuant to the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), 
establish  privacy  and  security  standards  that  limit  the  use  and  disclosure  of  individually  identifiable  health  information 
(known  as  “protected  health  information”)  and  require  the  implementation  of  administrative,  physical  and  technological 
safeguards to protect the privacy of protected health information and ensure the confidentiality, integrity and availability of 
electronic protected health information. Determining whether protected health information has been handled in compliance 
with applicable privacy standards and our contractual obligations can require complex factual and statistical analyses and 
may be subject to changing interpretation. Although we take measures to protect sensitive data from unauthorized access, 
use  or  disclosure,  our  information  technology  and  infrastructure  may  be  vulnerable  to  attacks  by  hackers  or  viruses  or 
breached due to employee error, malfeasance or other malicious or inadvertent disruptions. Any such breach or interruption 
could compromise our networks and the information stored there could be accessed by unauthorized parties, manipulated, 
publicly  disclosed,  lost  or  stolen.  Any  such  access,  breach  or  other  loss  of  information  could  result  in  legal  claims  or 

42 

 
proceedings, and liability under federal or state laws that protect the privacy of personal information, such as the HIPAA, the 
Health Information Technology for Economic and Clinical Health Act (“HITECH”), and regulatory penalties. Notice of breaches 
must be made to affected individuals, the Secretary of the Department of Health and Human Services, and for extensive 
breaches, notice may need to be made to the media or State Attorneys General. Such a notice could harm our reputation and 
our ability to compete. 

While we have in place formal policies and procedures related to the storage, collection, and processing of information, and 
have conducted data privacy audits, we continue to evaluate our compliance needs, including the need to conduct additional 
internal  and  external  data  privacy  audits  or  adopt  additional  policies  and  procedures,  to  ensure  our  compliance  with  all 
applicable data protection laws and regulations. Additionally, we do not currently have policies and procedures in place for 
assessing our third-party vendors’ compliance with applicable data protection laws and regulations. All of these evolving 
compliance  and  operational  requirements  impose  significant  costs,  such  as  costs  related  to  organizational  changes, 
implementing additional protection technologies, training employees and engaging consultants, which are likely to increase 
over  time.  In  addition,  such  requirements  may  require  us  to  modify  our  data  processing  practices  and  policies,  distract 
management or divert resources from other initiatives and projects, all of which could have a material adverse effect on our 
business, financial condition, results of operations and prospects. Any failure or perceived failure by us or our third-party 
vendors, collaborators, contractors and consultants to comply with any applicable federal, state or similar foreign laws and 
regulations relating to data privacy and security, could result in damage to our reputation, as well as proceedings or litigation 
by governmental agencies or other third parties, including class action privacy litigation in certain jurisdictions, which would 
subject us to significant fines, sanctions, awards, penalties or judgments, all of which could have a material adverse effect 
on our business, financial condition, results of operations and prospects. 

Increased scrutiny of our environmental, social or governance responsibilities may result in additional costs and risks, and may 
adversely impact our reputation, employee retention, and willingness of customers and suppliers to do business with us. 

Investor advocacy groups, institutional investors, investment funds, proxy advisory services, stockholders, and customers 
are  increasingly  focused  on  environmental,  social,  and  governance  (“ESG”)  practices  of  companies.  Additionally,  public 
interest and legislative pressure related to public companies’ ESG practices continues to grow. If our ESG practices fail to 
meet regulatory requirements or investor or other industry stakeholders' evolving expectations and standards for responsible 
corporate citizenship in areas including environmental stewardship, support for local communities, Board of Director and 
employee  diversity,  human  capital  management,  employee  health  and  safety  practices,  product  quality,  supply  chain 
management, corporate governance and transparency, and employing ESG strategies in our operations, our brand, reputation 
and employee retention may be negatively impacted and customers and suppliers may be unwilling to do business with us. 
In addition, as we work to align our ESG practices with industry standards, we will likely continue to expand our disclosures 
in these areas and doing so may result in additional costs and require additional resources to monitor, report, and comply 
with our various ESG practices. If we fail to adopt ESG standards or practices as quickly as stakeholders desire, report on our 
ESG  efforts  or  practices  accurately,  or  satisfy  the  expectations  of  stakeholders,  our  reputation,  business,  financial 
performance, and growth may be adversely impacted.

LEGAL PROCEEDINGS  

U.S. District Court Proceedings 

On September 26, 2019, Personal Genomics of Taiwan, Inc. (“PGI”) filed a complaint in the U.S. District Court for the District 
of Delaware against us for patent infringement (C.A. No. 19-cv-1810) (the “PGI District Court matter”). The matter from this 
complaint is based on PGI’s U.S. Patent No. 7,767,441 (the “‘441 Patent”). We plan to vigorously defend in this matter. On 
November 20,  2019,  we  filed  our  answer  to  the  complaint,  denying  infringement  and  seeking  a  declaratory  judgement  of 
invalidity of the ‘441 Patent. 

43 

 
On June 22, 2020, we filed a petition requesting institution of an inter-partes review ("IPR") to the Patent Trial and Appeals 
Board (the “Board”) at the United States Patent Office requesting the Board to find a set of claims in the ‘441 Patent invalid. 
On June 27, 2020, we filed a second petition requesting institution of an IPR requesting the Board to find another set of claims 
in the ‘441 Patent invalid. The two petitions (the “PacBio IPR Petitions”) requesting IPRs assert that all of the claims relevant 
to the PGI complaint are invalid. On January 19, 2021, the Board ordered that both PacBio IPR Petitions be instituted on all 
grounds presented. On January 18, 2022, the Board issued decisions on the two IPRs. In one IPR, all challenged claims were 
found  unpatentable,  including  PGI’s  core  device  claims.  In  the  second  IPR,  the  Board  did  not  find  the  disputed  claims 
unpatentable. We are appealing the decision in the second IPR to the U.S. Court of Appeals for the Federal Circuit. 

On August 19, 2020, the court ordered a stay of the PGI District Court matter based on a joint stipulation by the parties pending 
a final written decision on the IPRs. Following the final decision on the IPRs described above, on February 2, 2022, the judge 
ordered that the PGI District Court matter be reopened. However, in a subsequent order dated September 15, 2022, the judge 
stayed the PGI District Court matter pending a final decision by the U.S. Court of Appeals for the Federal Circuit regarding the 
appeal described above. We plan to vigorously defend against the remaining claims. 

In December 2022, Take2 Technologies, Ltd. and the Chinese University of Hong Kong filed a complaint in the U.S. District 
Court for Delaware against us alleging infringement of U.S. Patent No. 11,091,794 (the “’794 Patent”) (C.A. No. 22- cv-01595). 
The complaint alleges that our Sequel® II systems, Sequel IIe Systems, and Revio™ Systems that operate version 11.0 or later 
of the SMRT® Link software, infringe the ‘794 Patent. The complaint seeks unspecified monetary damages and an order 
enjoining us from infringing the ’794 Patent. We filed a motion to dismiss on February 14, 2023. We believe the infringement 
allegations in the complaint lack merit and we intend to vigorously defend in this matter. 

Proceedings in China 

On May 12, 2020, PGI filed a complaint in the Wuhan Intermediate People’s Court in China alleging infringement of one or 
more claims of China patent No. CN101743321B (the “CN321 Patent”), which is related to the ‘441 Patent. On November 23, 
2020 we filed an Invalidation Petition at the China National Intellectual Property Administration (CNIPA) demonstrating the 
invalidity of the claims in the CN321 Patent on grounds of insufficient disclosure, and the lack of support, essential technical 
features, clarity, novelty, and inventiveness. A hearing in the invalidation proceeding at the CNIPA was held on April 29, 2021. 
On September 2, 2021, the CNIPA issued its decision on the Invalidation Petition and determined that all claims (1-61) of the 
CN321 patent were invalid. On December 1, 2021, PGI filed an appeal with the Beijing IP Court, contesting the CNIPA decision. 
We filed a petition with the Wuhan Intermediate People’s court requesting dismissal of the infringement action based on the 
CNIPA  invalidation  decision,  and  PGI  filed  a  petition  to  withdraw  its  complaint.  The  Wuhan  Intermediate  People’s  court 
granted PGI’s petition and dismissed the infringement action in May 2022. 

Other Proceedings 

From time to time, we may also be involved in a variety of other claims, lawsuits, investigations, and proceedings relating to 
securities  laws,  product  liability,  patent  infringement,  contract  disputes,  employment,  and  other  matters  that  arise  in  the 
normal course of our business. In addition, third parties may, from time to time, assert claims against us in the form of letters 
and other communications. 

We record a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the 
loss can be reasonably estimated. We currently do not believe that the ultimate outcome of any of the matters described 
above is probable or reasonably estimable, or that these matters will have a material adverse effect on our business; however, 
the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse 
impact on us because of litigation and settlement costs, diversion of management resources, and other factors.

Overview and Outlook 

About PacBio 

We are a premier life science technology company that is designing, developing, and manufacturing advanced sequencing 
solutions that enable scientists and clinical researchers to improve their understanding of the genome and ultimately, resolve 
genetically complex problems. 

Our products and technology under development stem from two highly differentiated core technologies focused on accuracy, 
quality, and completeness, which include our existing HiFi long-read sequencing technology and our emerging Sequencing 
by  Binding  (SBB®)  short-read  sequencing  technology.  Our  products  address  solutions  across  a  broad  set  of  research 
applications including human genomics, plant and animal sciences, infectious disease and microbiology, oncology, and other 
emerging applications.  

Our  focus  is  on  providing  our  customers  with  advanced  sequencing  technologies  with  higher  throughput  and  improved 
workflows that we believe will enable dramatic advancements in routine healthcare.  

Our  customers  include  academic  and  governmental  research  institutions,  commercial  testing  and  service  laboratories, 
genome  centers,  public  health  labs,  hospitals  and  clinical  research  institutes,  contract  research  organizations  (CROs), 
pharmaceutical companies, and agricultural companies. 

As of December 31, 2022, our commercial team is comprised of approximately 195 employees, including 57 quota-carrying 
representatives, many with advanced degrees in biology and significant experience in the genomics industry. 

Strategic Objectives 

2022 was a productive year for us as we set out to transform the company, scale the business, and drive adoption for our 
advanced sequencing technologies. 

Our 2023 strategic objectives are to:  

•  Drive rapid adoption of RevioTM by converting existing Sequel II/IIe customers and attracting new PacBio customers  
•  Demonstrate Onso’s extraordinary level of accuracy in the field and show how it can transform research in needle-

in-haystack applications  

•  Progress development of ultra-high-throughput and bench top long-read sequencers and next generation SBB 

short-read sequencer  

•  Leverage current infrastructure to drive toward positive cash flow  
•  Expand partnerships across ecosystem and workflow to drive customer adoption of SBB short-read sequencing 

and HiFi long-read sequencing 

We will continue to leverage our commercial organization and make significant improvements in the efficiency and usability 
of our products to seek to reach a broader customer base. We believe the commercial investments we have recently made 
will further help drive growth in our business.  

46 

 
To increase the adoption of HiFi sequencing, we have various development programs in progress to expand our product 
portfolio as well as increase the throughput and improve the usability of our existing sequencing technologies. We continue 
to focus on programs to accelerate new platform launches in the near to mid-term as well as increase applications for our 
technologies. In October 2022, we announced Revio, our new HiFi long-read sequencing system. We began taking orders in 
the fourth quarter of 2022 and expect to commence commercial Revio shipments in March 2023. To address the oncology 
research markets with a highly differentiated alternative to existing third-party short-read sequencing products already on the 
market, we are also progressing development of OnsoTM, our SBB short-read platform. We began taking orders in January 
2023 and remain on track for commercial shipment in the second quarter of 2023.   

We continue to believe that with the capabilities of our HiFi chemistry and SMRT technology, we can be a market leader in 
whole-genome clinical sequencing. Leading institutions have adopted our products to study rare and inherited disease. We 
believe  the  market  opportunity  for  clinical  sequencing  is  significant  and  could  drive  substantial  revenue  growth  for  the 
company. We plan to continue to pursue partner collaborations where the technologies being developed or applications being 
considered  extend  beyond  whole-genome  clinical  sequencing.  Collaborative  arrangements  add  to  the  awareness  of  our 
products and service offerings and may drive new applications for use of our technology. 

Financial Overview 

Broader  macroeconomic  dynamics  including  rising  inflation,  global  supply  chain  constraints,  volatile  capital  markets, 
competition, and lockdown restrictions associated with COVID-19 have adversely impacted our customers and lengthened 
customer sales cycles. Additionally, lock downs in China have led to lower than previously anticipated revenue in the Asia-
Pacific region as customers had difficulty accessing labs and lower sample volumes from which to sequence. We expect 
some headwinds from a strengthening U.S. dollar, which impacts our revenue denominated in EUR and GBP but also impacts 
purchasing power of our customers in Asia as a stronger U.S. dollar makes buying our products more expensive.  

Ongoing global supply chain constraints and rising inflation are also increasing our costs; as a result, we expect these costs 
to impact gross margins and cash flow. Due to the rising costs from global supply chain constraints and rising inflation, we 
are  moderating  our  hiring  with  the  aim  of  reducing  our  operating  expense  growth  in  2023.  We  will  continue  to  prioritize 
investments to develop and commercialize our new products, prioritizing opportunities that will generate a return over the 
near to mid-term.  

The degree of further adverse impacts of COVID-19 on our business will depend on several factors, such as the duration and 
the  extent  of  the  pandemic,  as  well  as  actions  taken  by  governments,  businesses,  and  consumers  in  response  to  the 
pandemic, all of which continue to evolve and remain uncertain at this time. 

The COVID-19 pandemic and efforts to control its spread have significantly curtailed the movement of people, goods, and 
services worldwide, including in the regions in which we sell our products and services and conduct our business operations. 
We have been negatively impacted by the COVID-19 pandemic and expect to continue to be impacted by COVID-19 for the 
foreseeable  future.  Due  to  the  uncertain  scope  and  duration  of  the  pandemic,  we  cannot  reasonably  estimate  the  future 
impact to our operations and financial results. 

The spread of COVID-19 caused us to modify our business practices, including limiting some of our commercial operations 
and  limiting  certain  employees  from  working  in  the  office.  Starting  in  April  2022,  we  invited  employees  located  near  our 
reopened offices to return to the office.  

See the Risk Factors section for further discussion of the possible impact of the COVID-19 pandemic on our business.

Key highlights of our 2022 consolidated financial results include the following:  

•  Revenue decreased $2.2 million, or 2%, to $128.3 million for the year ended December 31, 2022, as compared to 
$130.5 million for the year ended December 31, 2021. The decline was primarily caused by a decrease in instrument 
revenue, which was due in part to the robust demand for Revio, displacing previously anticipated Sequel IIe sales in 
the fourth quarter of 2022. We received orders in the fourth quarter of 2022 for 76 Revio systems with delivery in 
2023. The decline in instrument revenue was partially offset by an increase in consumables revenue of $7.8 million. 

•  Gross profit as a percentage of revenue (gross margin) was 38.2% for the year ended December 31, 2022, compared 
to  45.1%  for the  year  ended  December  31,  2021. Gross  margin  declined  due  primarily  to  adjustments  for  excess 
inventory, either on hand or at our contract manufacturer, related to a faster than expected ramp in Revio demand, 
which  resulted  in  a  faster  than  expected  decline  in  Sequel  II/IIe  demand  upon  the  launch  of  Revio,  as  well  as  a 
decrease in instrument volume and higher overall product costs. Our gross margin in future periods will depend on 
several  factors,  including  new  product  transitions,  strategic  product  pricing;  product  mix;  sales  of  higher-margin 
consumables; supply chain constraints and inflation increasing costs of raw materials; manufacturing capacity and 
production volumes impacting the cost of inventory; freight costs; and excess or obsolete inventories. 

•  Loss from operations increased $96.8 million or 46%, to $307.2 million for the year ended December 31, 2022, as 
compared to $210.4 million for the year ended December 31, 2021, driven primarily by an increase of $86.9 million 
of operating expenses, including a $80.1 million increase in research and development expenses, a $36.7 million 
increase in sales, general, and administrative expenses, and a $1.2 million increase in the change in the fair value of 
the  contingent  consideration,  partially  offset  by  a  $31.1  million  decrease  in  non-recurring  merger-related  costs 
incurred in 2021. See Note 2. Business Acquisitions for further details.  

•  Cash, cash equivalents, and short-term investments were $772.3 million at December 31, 2022, which represents a 

26% decrease compared to the balance at December 31, 2021. 

Recent Developments 

Product Announcements 

On October 25, 2022, we announced two new sequencing platforms, Revio and Onso. 

Revio  is  a  new  long-read  sequencing  system  designed  to  enable  the  use  of  HiFi  sequencing  for  large  studies  in  human 
genetics, cancer research, and agricultural genomics. We expect to commence commercial Revio shipments in March 2023. 

Onso, a short-read DNA sequencing system, is designed to deliver industry-leading sensitivity and specificity for novel insights 
in oncology, disease research, and other applications. We commenced the beta program for Onso in the fourth quarter of 
2022. We began taking orders for Onso during the first quarter of 2023 and remain on track for commercial shipment in the 
second quarter of 2023. 

January 2023 Public Offering 

On January 27, 2023, we issued and sold an aggregate of 20,125,000 shares of our common stock at a purchase price of 
$10.00 per share pursuant to an automatic shelf registration statement filed on  Form S-3 (File No. 333-249999) with the 
Securities and Exchange Commission, resulting in aggregate gross proceeds of approximately $201.3 million.

The  decrease  in  product  revenue  resulted  primarily  from  a  decrease  of  $12.6  million  in  instrument  revenue,  which  was 
partially offset by an increase of $7.8 million in consumable revenue.  

The  decrease  in  instrument  revenue  was  primarily  due  to  fewer  instruments  sold.  We  believe  this  decrease  was  driven 
primarily by the anticipation of and robust demand for Revio, displacing previously anticipated Sequel IIe sales in 2022. At 
December 31, 2022, our installed base was 512 Sequel II and Sequel IIe systems compared to the 374 systems at December 
31, 2021. We anticipate that sales volumes of Sequel II/IIe may decline as a result of the announcement of Revio and its 
anticipated availability for shipment in the first quarter of 2023. During the fourth quarter of 2022, we received orders for 76 
Revio systems for delivery in 2023 and expect to see continued growth in Revio system sales, as well as the Onso system for 
which we began taking orders in January 2023. 

The increase in consumable sales was primarily due to higher Sequel II/IIe consumables sales attributable to the growth in 
the instrument installed base. Consumable growth reflects approximately 24% growth in Sequel II and IIe SMRT cells shipped 
in 2022, as compared to 2021. 

The increase in service and other revenue was primarily due to product services contracts sold on the growing installed base.

Cost of Revenue, Gross Profit, and Gross Margin 

The increase in the cost of product revenue was driven primarily by adjustments for excess inventory primarily resulting from 
adjustments for excess inventory related to a faster than expected ramp in Revio demand, which resulted in a faster than 
expected decline in Sequel II/IIe demand upon the launch of Revio, as well as higher overall product costs.  

The decrease in the cost of service and other revenue was primarily due to lower service personnel costs.  

The loss on purchase commitment was $3.7 million for the year ended December 31, 2022. The purchase commitment loss 
is based on an estimate of future excess inventory related to a supply agreement with a third-party vendor, for which we do 
not expect to have related sales. 

Gross profit decreased $9.8 million, or 17%. Gross margin was 38.2% for the year ended December 31, 2022 compared to 
45.1% for the year ended December 31, 2021. The decrease in gross margin percentage was primarily due to adjustments 
for excess inventory, either on hand or at our contract manufacturer, related to a faster than expected ramp in Revio demand, 
which resulted in a faster than expected decline in Sequel II/IIe demand upon the launch of Revio, as well as a decrease in 
instrument sales volume and higher product costs, which was partially offset by consumables volumes and higher service 
and other revenues during the year ended December 31, 2022, compared to the year ended December 31, 2021. 

We expect our gross margin will trend slightly lower during the first half of 2023, due in part to new product transitions and 
the impacts of inflation and increased supply chain costs. The global shortage of semiconductors continues to be a challenge 
for us in our supply chain and has resulted in cost increases that have and may continue to adversely impact margins. During 
these periods of shortages or delays, the price of components may increase, or the components may not be available at all. 
Additionally, in response to the surge in COVID-19 infections in 2022, the Chinese government-imposed lockdowns in certain 
parts of the country, which has had, and may continue to have, a negative impact on manufacturing and/or supply chains, as 
well as customer demand for our products and demand through certain distributors. We may not be able to secure enough 
components  at  reasonable  prices  or  of  acceptable  quality  to  build  new  products  in  a  timely  manner  in  the  quantities  or 
configurations needed. Accordingly, our revenue and gross margins could suffer until other sources can be developed.  

Research and Development Expense 

The  increase  in  research  and  development  expense  was  primarily  driven  by  an  increase  of  $34.1  million  in  product 
development  costs  and  an  increase  of  $33.9  million  in  personnel  expenses,  including  the  acquired  workforce  from  the 
Omniome acquisition. In addition, facilities and information technology related expenses associated with our research and 
development activities increased $9.9 million to support our operational expansion during the year ended December 31, 2022, 
compared to the year ended December 31, 2021. Research and development expense included share-based compensation 
expense of $30.7 million and $20.3 million during the twelve months ended December 31, 2022 and 2021, respectively.  

We  will  continue  to  focus  a  significant  portion  of  our  resources  on  developing  new  products  and  solutions,  including 
improving the efficiency and usability of existing products, developing new solutions, software, workflows and applications 
leveraging our core technologies. We anticipate that our spend will decline slightly in 2023 due to new product transitions. 
Additionally,  we  have  collaborated  and  expect  to  continue  to  collaborate  with  strategic  partners  to  develop  sequencing 
solutions and expand the application of our technology.  

Sales, General, and Administrative Expense 

The increase in sales, general, and administrative expense was primarily driven by an increase of $13.0 million in personnel 
costs,  $9.7  million  in  marketing  expenses,  including  costs  incurred  in  connection  with  product  launches,  $4.7  million  in 
consulting  and  professional  services,  $4.2  million  in  travel-related  expenses,  and  $2.7  million  in  facilities  expenses  and 
information technology related expenses. Sales, general, and administrative expense included share-based compensation 
expense of $43.1 million and $35.4 million during the twelve months ended December 31, 2022 and 2021, respectively. We 
anticipate  sales,  general,  and  administrative  expense  to  continue  to  increase  primarily  as  a  result  of  the  new  product 
commercialization efforts.  

Change in Fair Value of Contingent Consideration 

The  change  in  fair  value  of  contingent  consideration  during  the  year  ended  December  31,  2022,  represents  the 
remeasurement impact of the contingent consideration of $200 million (composed of $100 million in cash and $100 million 
in shares of our common stock) that is due upon the achievement of a milestone, defined as the first commercial shipment 
to  a  customer  of  both  an  instrument  and  related  consumables,  utilizing  SBB  technology.  The  increase  in  contingent 
consideration liability was primarily due to the passage of time and changes in the probabilities of milestone achievement, 
offset by increases in the discount rate. 

Loss from Continuation Advances from Illumina 

As part of the Termination Agreement, Illumina paid us Continuation Advances totaling $52.0 million, which was repayable 
without interest to Illumina if, within two years of March 31, 2020, we entered into, or consummated a Change of Control 

50 

 
Transaction or raised at least $100 million in a single equity or debt financing (that may have multiple closings), with the 
amount repayable dependent on the amount raised by us.  

Resulting from the issuance and sale of $900 million of 1.50% Convertible Senior Notes due February 15, 2028, $52.0 million 
of Continuation Advances were paid without interest to Illumina in February 2021 and recorded as other expense in the year 
ended December 31, 2021. 

Interest Expense 

The increase in interest expense for the year ended December 31, 2022, was primarily due to the twelve months of interest 
incurred on the $900 million of 1.50% Convertible Senior Notes due February 15, 2028, that we issued on February 16, 2021 
during the year ended December 31, 2022 compared to only ten months of interest during the year ended December 31, 2021. 

Other Income, Net 

The increase in other income, net was primarily driven by a $8.4 million increase in interest income, partially offset by a $0.6 
million increase in foreign exchange loss.  

Benefit from Income Taxes 

A deferred income tax benefit of $93.6 million for the year ended December 31, 2021, is related to the release of the valuation 
allowance  for  deferred  tax  assets  due  to  the  recognition  of  deferred  tax  liabilities  in  connection  with  the  Omniome  and 
Circulomics acquisitions. We maintain a full valuation allowance on the net deferred tax assets of our U.S. entities as we 
have concluded that it is more likely than not that we will not realize our deferred tax assets. Accordingly, this benefit from 
income taxes is reflected on our Consolidated Statements of Operations and Comprehensive (Loss) Income for the year ended 
December 31, 2021. 

Liquidity and Capital Resources  

Our  primary  sources  of  liquidity,  other  than  our  holdings  of  cash,  cash  equivalents,  and  investments,  has  primarily  been 
through the issuance of debt or equity securities, together with cash flow from operating activities. For example, in January 
2023, as discussed above, we issued and sold an aggregate of 20,125,000 shares of our common stock in a follow-on public 
offering for aggregate gross proceeds of approximately $201.3 million. We have historically incurred, and expect to continue 
to incur, operating losses and generate negative cash flows from operations on an annual basis due to the investments we 
intend to make as described in Results of Operations above, and as a result, we may require additional capital resources to 
execute our strategic initiatives to grow our business. 

Cash, cash equivalents, and investments  

As of December 31, 2022, we had $772.3 million in cash, cash equivalents, and investments, compared to $1.0 billion at 
December 31, 2021. The decrease was primarily attributable to $263.2 million cash used in operating activities for the twelve 
months ended December 31, 2022.  

Convertible Senior Notes 

At December 31, 2022, we had $900 million of principal Convertible Senior Notes outstanding resulting from our February 9, 
2021,  issuance  of  convertible  notes  due  2028  (the  “Notes”)  with  an  aggregate  principal  of  $900  million.  The  Notes  bear 
interest at a rate of 1.50% per annum. Interest on the Notes is payable semi-annually in arrears on February 15 and August 
15 commencing on August 15, 2021. The Notes will mature on February 15, 2028, subject to earlier conversion, redemption, 
or  repurchase.  The  proceeds  from  the  issuance  of  the  convertible  notes  are  being  used  to  fund  operations,  strategic 
investments, and capital requirements.  

The Notes are convertible at the option of the holder at any time until the second scheduled trading day prior to the maturity 
date, including in connection with a redemption by the Company. The Notes are convertible into shares of our common stock 
based on an initial conversion rate of 22.9885 shares of common stock per $1,000 principal amount of the Notes (which is 
equal to an initial conversion price of $43.50 per share), in each case subject to customary anti-dilution and other adjustments 
as  a  result  of  certain  extraordinary  transactions.  Upon  conversion  of  the  Notes,  we  may  elect  to  settle  such  conversion 
obligation in shares, cash or a combination of shares and cash.  

With certain exceptions, upon a change of control of the Company or the failure of our common stock to be listed on certain 
stock exchanges, the holders of the Notes may require that we repurchase all or part of the principal amount of the Notes at 
a purchase price of par plus unpaid interest up to, but excluding, the maturity date. 

The Indenture includes customary “events of default,” which may result in the acceleration of the maturity of the Notes under 
the Indenture. The Indenture also includes customary covenants for convertible notes of this type. 

See Note 7. Convertible Senior Notes for further details.

Additional Capital Requirements  

We believe that our existing cash, cash equivalents, and investments will be sufficient to fund our projected operating and 
capital requirements for at least the next 12 months from the date of filing of this Annual Report on Form 10-K for the year 
ended December 31, 2022. Operating needs include planned costs to operate our business, including costs to fund working 
capital  and  capital  expenditures.  Recent  and  expected  working  and  other  capital  requirements,  in  addition  to  the  above 
matters, include:  

•  Our purchase orders and contractual obligations of approximately $145.7 million as of December 31, 2022, which 
consist  of  open  purchase  orders  and  contractual  obligations  in  the  ordinary  course  of  business,  including 
commitments with contract manufacturers and suppliers for which we have not received the goods or services. A 
majority  of  these  purchase  obligations  are  due  within  a  year.  Although  open  purchase  orders  are  considered 
enforceable  and  legally  binding,  the  terms  generally  allow  us  the  option  to  cancel,  reschedule  and  adjust  our 
requirements based on our business needs prior to the delivery of goods or performance of services. 

•  As described in more detail in Note 8 - Commitments and Contingencies in the Notes to the Consolidated Financial 
Statements, we signed a Supply Agreement, which was amended in October 2022, with a supplier for the purchase 
of certain products over the period of 2023 through 2026. As part of the Supply Agreement, we made a $9.0 million 
deposit during the year ended December 31, 2022, and will pay an additional deposit of $6.0 million in 2023, to secure 
the  supply  of  certain  products  through  the  term  of  the  contract.  If  we  breach  the  minimum  volume  purchase 
commitment during any applicable year, the supplier is entitled to retain a portion or all of the deposit corresponding 
to  that  year.  If  we  terminate  the  Supply  Agreement  before  January  15,  2027,  Supplier  will  refund  the  remaining 
balance of the Deposit. If the supplier breaches its minimum volume supply commitment during any applicable year 
or portions thereof, our remedies include termination, pursuit of damages, or pursuit of specific performance. If, on 
or before October 31, 2024, we commit to purchasing a set amount of additional products during the calendar year 
2026, Supplier will increase its maximum capacity guarantee to meet the additional demand. Should we exercise this 
option, we will be required to make an additional deposit of $5.0 million to Supplier within 30 days of the exercise. 

•  Our research and development expenditures of $193.0 million in 2022 and $112.9 million in 2021. While we expect 
to continue our investment in research and development in 2023, including enhancements of our existing products, 
and  continued  development  of  our  Revio  and  Onso  systems  and  other  new  technology  and  products,  we  expect 
research and development expenses to decline slightly in 2023 as compared to the year ended December 31, 2022 
due to new product transitions.  

•  Cash outflows for capital expenditures of $16.8 million in 2022 and $5.9 million in 2021. We expect to continue to 
invest in capital expenditures in fiscal 2023 to continue to support manufacturing and expansion of our business, 
and anticipate a slight decline in 2023 as compared to the year ended December 31, 2022.   

•  Amounts  related  to  future  lease  payments  for  operating  lease  obligations  at  December  31,  2022,  totaling  $58.6 

million, with $12.0 million expected to be paid within the next 12 months. 

•  Amounts due under the term loan acquired in connection with Omniome at December 31, 2022, totaling $2.3 million, 
with $1.8 million expected to be paid within the next 12 months. Please see Note 6. Balance Sheet Components for 
additional information. 

•  Payments made to third party collaborators to help advance our technologies and the capabilities of our products. 
We may also choose to drive investments to help create an ecosystem of customers, partners, and collaborators 
whose expertise and offerings complement and enhance the capabilities and utility of our technology and increase 
genomic data available on our platforms. 

•  Payments related to licensing and other arrangements, which are cancelable license agreements with third parties 
for certain patent rights and technology. Under the terms of these agreements, we may be obligated to pay royalties 
based  on  revenue  from  the  sales  of  licensed  products,  or  minimum  royalties,  whichever  is  greater,  and  license 
maintenance  fees.  The  future  license  maintenance  fees  and  minimum  royalty  payments  under  the  license 
agreements are not deemed to be material. 

Our future capital requirements and the adequacy of our available funds will depend on many factors, including:  

the pace of adoption of our products and our ability to obtain new customers in markets;  

•  our ability to successfully commercialize and develop products and solutions that address customer needs; 
• 
• 
•  our  ability  to  manage  manufacturing  and  production  costs,  including  purchase  obligations,  and  litigation  costs, 
including the costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; and 

the progress of our research and development programs and our ability to initiate or expand research programs;  

• 

the extent to which we engage in collaborations with partners and acquire other businesses or technologies. 

52 

 
If  economic,  financial,  business,  or  other  factors  adversely  affect  our  ability  to  fund  our  projected  operating  cash 
requirements, we may be required to obtain funding through traditional or alternative sources of financing. We cannot be 
certain that funds will be available on favorable terms, or at all. If we are required and unable to raise additional capital when 
desired, our business, operating results, and financial condition may be adversely affected.

Our  primary  uses  of  cash  in  operating  activities  include  the  development  of  future  products  and  product  enhancements, 
manufacturing, and support functions related to our sales, general, and administrative activities.  

Cash used in operating activities for the year ended December 31, 2022, of $263.2 million was due primarily to a $314.2 
million net loss that was partially offset by non-cash items such as share-based compensation of $78.6 million, depreciation 
of $9.5 million, amortization of right-of-use assets of $6.9 million, inventory provision of $6.0 million, and a change in the 
estimated fair value of contingent consideration of $2.4 million. Cash flow impact from changes in net operating assets and 
liabilities of $54.0 million, was primarily attributable to increases of $33.9 million in inventory, net, $12.3 million in prepaid 
expenses and other assets, and decreases of $7.7 million in operating lease liabilities, $3.7 million in accrued expenses, and 
$3.7 million in deferred revenue, partially offset by a decrease of $5.5 million in accounts receivable, net, an increase of $1.0 
million in accounts payable, and $0.9 million in other liabilities. 

Cash used in operating activities for the year ended December 31, 2021, of $111.2 million was due primarily to a $181.2 
million net loss, which includes a $93.6 million deferred income tax benefit, that was partially offset by a loss of $52.0 million 
from Continuation Advances repaid to Illumina that is considered a financing activity, non-cash items such as share-based 
compensation of $73.4 million, depreciation of $7.2 million, amortization of right-of-use assets of $4.0 million and a net cash 
inflow from changes in operating assets and liabilities of $20.3 million. Cash flow impact from changes in operating assets 
and  liabilities  was  primarily  attributable  to  increases  of  $25.7  million  in  deferred  revenue,  an  increase  of  $15.3  million  in 
accrued  expenses  and  an  increase  of  $6.4  million  in  accounts  payable  partially  offset  by  an  increase  of  $13.1  million  in 
inventory, net, an increase of $7.2 million in accounts receivable, net, an increase of $1.0 million in prepaid expenses and 
other assets, and a decrease of $5.0 million in operating lease liabilities. 

Investing Activities  

Our  investing  activities  consist  primarily  of  capital  expenditures  and  investment  purchases  and  maturities.  Cash  used  in 
investing activities for the year ended December 31, 2022, was due primarily to capital expenditures of $16.8 million and 
purchases of investments of $442.8 million offset by maturities of investments of $575.8 million. 

Cash used in investing activities for the year ended December 31, 2021, was due primarily to net purchases of investments 
of $352.8 million, cash paid, net of cash acquired, of $319.8 million for the acquisitions of Omniome and Circulomics, and 
purchases of property and equipment of $5.9 million. 

Financing Activities  

Cash provided by financing activities during the year ended December 31, 2022, resulted from net proceeds of $11.2 million 
from  the  issuance  of  common  stock  through  our  equity  compensation  plans,  partially  offset  by  $1.6  million  due  to  the 
payment of notes payable.  

Cash provided by financing activities during the year ended December 31, 2021, resulted from net proceeds of $895.5 million 
from our February 2021 issuance of $900 million of 1.50% Convertible Senior Notes after deducting debt issuance costs, net 
proceeds of $294.8 million from our September 2021 private placement of common stock after deducting issuance costs 
and proceeds of $31.8 million from the issuance of common stock through our equity compensation plans, partially offset 
by $52.0 million of Continuation Advances repaid to Illumina. 

Off-Balance Sheet Arrangements 

As of December 31, 2022, we did not have any off-balance sheet arrangements. 

In the ordinary course of business, we enter into standard indemnification arrangements. Pursuant to these arrangements, 
we  indemnify,  hold  harmless,  and  agree  to  reimburse  the  indemnified  parties  for  losses  suffered  or  incurred  by  the 
indemnified party in connection with any trade secret, copyright, patent or other intellectual property infringement claim by 
any third party with respect to its technology, or from claims relating to our performance or non-performance under a contract, 

53 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
any  defective  products  supplied  by  us,  or  any  acts  or  omissions,  or  willful  misconduct,  committed  by  us  or  any  of  our 
employees,  agents  or  representatives.  The  term  of  these  indemnification  agreements  is  generally  perpetual  after  the 
execution of the agreement. The maximum potential amount of future payments we could be required to make under these 
agreements is not determinable because it involves claims that may be made against us in future periods but have not yet 
been  made.  To  date,  we  have  not  incurred  costs  to  defend  lawsuits  or  settle  claims  related  to  these  indemnification 
agreements. 

We  also  enter  and  have  entered  into  indemnification  agreements  with  our  directors  and  officers  that  may  require  us  to 
indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited 
by  applicable  law.  In  addition,  we  may  have  obligations  to  hold  harmless  and  indemnify  third  parties  involved  with  our 
fundraising efforts and their respective affiliates, directors, officers, employees, agents or other representatives against any 
and  all  losses,  claims,  damages  and  liabilities  related  to  claims  arising  against  such  parties  pursuant  to  the  terms  of 
agreements entered into between us and such third parties in connection with such fundraising efforts. To the extent that 
such indemnification obligations apply to the lawsuits described in Legal Proceedings in Part I, Item 3 of this Annual Report 
on  Form  10-K,  any  associated  expenses  incurred  are  included  within  the  related  accrued  litigation  expense  amounts.  No 
additional liability associated with such indemnification agreements has been recorded as of December 31, 2022. 

Critical Accounting Policies and Estimates  

Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon our Consolidated 
Financial Statements, which we have prepared in accordance with U.S. GAAP. The preparation of these financial statements 
requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, 
cost of revenue, and operating expenses, and related disclosure of contingent assets and liabilities. Management based its 
estimates  on  historical  experience  and  on  various  other  assumptions  that  it  believes  to  be  reasonable  under  the 
circumstances, the results of which form the basis for making judgements about the carrying values of assets and liabilities 
that are not readily apparent from other sources. Actual results may differ materially from these estimates under different 
assumptions or conditions. 

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about 
matters that are highly uncertain at the time the estimate is made, if different estimates reasonably could have been used, or 
if changes in the estimate that are reasonably likely to occur could materially impact the financial statements.  

Revenue Recognition  

Our revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of our 
instruments  and  related  consumables;  service  and  other  revenue  consist  primarily  of  revenue  earned  from  product 
maintenance agreements. 

We account for a contract with a customer when there is a legally enforceable contract between us and the customer, the 
rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is 
probable.  Revenues  are  recognized  when  control  of  the  promised  goods,  or  services  is  transferred  to  our  customers,  or 
services are performed, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods 
or services.  

Our  instrument  sales  are  generally  sold  in  a  bundled  arrangement  and  commonly  include  the  instrument,  instrument 
accessories, training, and consumables. For such bundled arrangements, we account for individual products and services 
separately if they are distinct, that is, if a product or service is separately identifiable from other items in the bundled package 
and if a customer can benefit from it on its own or with other resources that are readily available to the customer. Installation 
services are considered distinct from the instrument. Therefore, instrument revenue is recognized upon transfer of control 
of the asset to the customer, which is generally upon delivery for sales made to our non-distributor customers and upon 
shipment for sales made to our distributor customers. 

The consideration for bundled arrangements is allocated between separate performance obligations based on their individual 
standalone selling price. We determine the best estimate of standalone selling price using average selling prices over a 12-
month  period  combined  with  an  assessment  of  current  market  conditions.  If  the  standalone  selling  price  is  not  directly 
observable,  we  rely  on  estimates  by  considering  multiple  factors  including,  but  not  limited  to,  overall  market  conditions, 
including  geographic  or  regional  specific  factors,  internal  costs,  profit  objectives,  pricing  practices,  and  other  observable 
inputs. We recognize revenues as performance obligations are satisfied by transferring control of the product or service to 
the customer or over the term of a product maintenance agreement with a customer. Our revenue arrangements generally 
do not provide a right of return. 

Certain  of  our  agreements  provide  options  to  customers  which  can  be  exercised  at  a  future  date,  such  as  the  option  to 
purchase our product at discounted prices, among others. In accounting for customer options, we determine whether an 
option is a material right and this requires us to exercise significant judgment. If a contract provides the customer an option 
to  acquire  additional  goods  or  services  at  a  discount  that  exceeds  the  range  of  discounts  that  we  typically  give  for  that 

54 

 
product or service for the same class of customer, or if the option provides the customer certain additional goods or services 
for free, the option may be considered a material right. If the contract gives the customer the option to acquire additional 
goods or services at their normal standalone selling prices, we would likely determine that the option is not a material right 
and, therefore, account for it as a separate performance obligation when the customer exercises the option. If the standalone 
selling  price  of  the  option  is  not  directly  observable,  an  estimated  standalone  selling  price  is  utilized  which  considers 
adjustments for discounts that the customer could receive without exercising the option and the likelihood that the option 
will be exercised. We may also utilize the alternative approach to estimate the standalone selling price, available pursuant to 
the applicable accounting guidance, to the extent we conclude the applicable criteria for using the alternative approach has 
been met. We update the transaction price for expected consideration, subject to constraint, each reporting period if our 
estimate of future goods to be ordered by customers change. 

Inventories  

Inventories  are  stated  at  the  lower  of  cost  or  net  realizable  value.  Cost  is  determined  using  the  first-in,  first-out  (“FIFO”) 
method. Adjustments to reduce the cost of inventory to its net realizable value, if required, are made for estimated excess or 
obsolete balances. Cost includes depreciation, labor, material, and overhead costs, including product and process technology 
costs  while  determining  net  realizable  value  of  inventories  involves  numerous  judgements,  including  projecting  future 
average selling prices, sales volumes, and costs to complete products in work in process inventories.   

We make inventory purchases and commitments to meet future shipment schedules based on forecasted demand for our 
products. The business environment in which we operate is subject to rapid changes in technology and customer demand. 
We  perform  a  detailed  assessment  of  inventory  each  period,  which  includes  a  review  of,  among  other  factors,  demand 
requirements,  product  life  cycle  and  development  plans,  component  cost  trends,  product  pricing,  product  expiration,  and 
quality issues. Based on our analysis, we record adjustments to inventory for potentially excess, obsolete, or impaired goods, 
when  appropriate,  to  report  inventory  at  net  realizable  value.  Inventory  adjustments  may  be  required  if  actual  demand, 
component costs, supplier arrangements, or product life cycles differ from our estimates. Any such adjustments would result 
in a charge to our results of operations. 

Business Combinations 

Under the acquisition method of accounting, we allocate the fair value of the total consideration transferred to the tangible 
and  identifiable  intangible  assets  acquired  and  liabilities  assumed  based  on  their  estimated  fair  values  on  the  date  of 
acquisition. The fair values assigned, defined as the price that would be received to sell an asset or paid to transfer a liability 
in  an  orderly  transaction  between  willing  market  participants,  are  based  on  estimates  and  assumptions  determined  by 
management. These valuations require us to make estimates and assumptions, especially with respect to intangible assets. 
We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, 
as  goodwill.  Costs  that  we  incur  to  complete  the  business  combination,  such  as  legal  and  other  professional  fees,  are 
expensed as they are incurred. 

In connection with certain acquisitions, contingent consideration can be earned by the sellers upon completion of certain 
future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition 
date  fair  value  of  the  contingent  consideration.  Changes  in  the  fair  value  of  contingent  consideration  subsequent  to  the 
acquisition  date  are  recognized  in  operating  expenses  in  our  consolidated  statements  of  operations  and  comprehensive 
(loss) income. 

We typically use the discounted cash flow method to value our acquired intangible assets. This method requires significant 
management judgment to forecast future operating results and utilizes significant assumptions such as assumed revenue 
growth rates, discount rates and obsolescence factors. The estimates we use to value and amortize intangible assets are 
consistent with the plans and estimates that we use to manage our business and are based on available historical information 
and industry estimates and averages. If the subsequent actual results and updated projections of the underlying business 
activity  change  compared  with  the  assumptions  and  projections  used  to  develop  these  values,  we  could  experience 
impairment charges. In addition, we have estimated the economic lives of certain acquired assets and these lives are used 
to  calculate  depreciation  and  amortization  expense.  If  our  estimates  of  the  economic  lives  change,  depreciation  or 
amortization expense could be accelerated or extended. We capitalize in-process research and development (IPR&D), which 
is considered indefinite lived until the completion or abandonment of the associated research and development efforts. Upon 
reaching  the  end  of  the  relevant  research  and  development  project  (i.e.,  upon  commercialization),  the  IPR&D  asset  is 
amortized over its estimated useful life. If the relevant research and development project is abandoned, the IPR&D asset is 
expensed in the period of abandonment. 

55 

 
If  the  initial  accounting  for  a  business  combination  is  incomplete  by  the  end  of  a  reporting  period  that  falls  within  the 
measurement period, we report provisional amounts in our financial statements. During the measurement period, we adjust 
the  provisional  amounts  recognized  at  the  acquisition  date  to  reflect  new  information  obtained  about  facts  and 
circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts 
recognized as of that date. We record these adjustments to the provisional amounts with a corresponding offset to goodwill. 
Any adjustments identified after the measurement period are recorded in the consolidated statements of income. 

We  acquired  $11.4  million  of  finite-lived  intangible  assets,  $400.0  million  of  IPR&D,  and  $410.0  million  of  goodwill  in 
connection with the acquisitions of Omniome and Circulomics in the third quarter of 2021.  

Goodwill and Intangible Assets with Indefinite Lives — Impairment Assessment 

Goodwill  and  other  intangible  assets  with  indefinite  useful  lives  (i.e.,  IPR&D)  are  not  amortized,  however  they  are  tested 
annually for impairment, in the second and fourth quarter of our fiscal year, respectively, and whenever events or changes in 
circumstances indicate that it is more likely than not that the fair value is less than the carrying value. Events that would 
indicate  impairment  and  trigger  an  interim  impairment  test  include,  but  are  not  limited  to,  unexpected  adverse  business 
conditions, economic factors, unanticipated technological changes or competitive activities, loss of key personnel and acts 
by governments or courts. 

We perform our goodwill impairment analysis at the reporting unit level. We have one reporting unit, which aligns with our 
reporting  structure  and  availability  of  discrete  financial  information.  During  the  goodwill  impairment  review,  we  assess 
qualitative factors to determine whether it is more likely than not that the fair value of our reporting unit is less than the 
carrying  amount,  including  goodwill.  The  qualitative  factors  include,  but  are  not  limited  to,  macroeconomic  conditions, 
industry and market considerations, and our overall financial performance. If, after assessing the totality of these qualitative 
factors, we determine that it is not more likely than not that the fair value of our reporting unit is less than the carrying amount, 
then  no  additional  assessment  is  deemed  necessary.  Otherwise,  we  proceed  to  compare  the  estimated  fair  value  of  the 
reporting unit with the carrying value, including goodwill. If the carrying amount of the reporting unit exceeds the fair value, 
we record an impairment loss based on the difference. If a quantitative assessment is performed, the evaluation includes 
management estimates of cash flow projections based on internal future projections and/or use of a market approach by 
looking at market values of comparable companies. Key assumptions include, but are not limited to, revenue and operating 
income  growth  rates,  discount  rates  and  other  factors.  We  consider  peer  revenues  and  earnings  trading  multiples  from 
companies that have operational and financial characteristics that are similar to the asset under measurement and estimated 
weighted-average costs of capital. Different assumptions from those made in our analysis could materially affect projected 
cash flows and the evaluation of assets for impairment. We also consider our market capitalization as a part of our analysis. 
We may elect to bypass the qualitative assessment in a period and proceed to perform the quantitative goodwill impairment 
test. 

During the IPR&D impairment review, we assess qualitative factors to determine whether it is more likely than not that the 
fair value of the IPR&D is less than the carrying amount. The qualitative factors include, but are not limited to, macroeconomic 
conditions, industry-specific conditions, and company-specific conditions. If, after assessing the totality of these qualitative 
factors, we determine that it is not more likely than not that the fair value of the IPR&D is less than the carrying amount, then 
no additional assessment is deemed necessary. Otherwise, we proceed to compare the estimated fair value of the IPR&D 
with the carrying value. If the carrying amount of the IPR&D exceeds the fair value, we record an impairment loss based on 
the  difference.  If  a  quantitative  assessment  is  performed,  the  evaluation  includes  management  estimates  of  cash  flow 
projections  based  on  internal  future  projections.  Key  assumptions  include,  but  are  not  limited  to,  revenue  and  operating 
income  growth  rates,  discount  rates  and  other  factors.  We  consider  peer  revenues  and  earnings  trading  multiples  from 
companies that have operational and financial characteristics that are similar to the asset under measurement and estimated 
weighted-average costs of capital. Different assumptions from those made in our analysis could materially affect projected 
cash flows and the evaluation of assets for impairment. We may elect to bypass the qualitative assessment in a period and 
proceed to perform the quantitative impairment test. 

56 

 
Intangible Assets and Other Long-Lived Assets — Impairment Assessment 

We perform regular reviews to determine if any event has occurred that may indicate that the carrying values of our intangible 
assets with finite lives and other long-lived assets are impaired. If indicators of impairment exist, we assess the recoverability 
of the affected assets by determining whether their carrying amounts exceed their undiscounted expected future cash flows. 
If  the  affected  assets  are not  recoverable,  we  estimate  the  fair  value  of  the  assets  and  record  an  impairment  loss  if  the 
carrying value exceeds the fair value. Factors that may indicate potential impairment include a significant decline in our stock 
price and market capitalization compared to net book value, significant changes in the ability of an asset to generate positive 
cash flows and the pattern of utilization of a particular asset. 

In order to estimate the fair values of identifiable intangible assets with finite lives and other long-lived assets, we estimate 
the present value of future cash flows from those assets. The key assumptions that we use in our discounted cash flow 
model are the amount and timing of estimated future cash flows to be generated by the asset over an extended period of 
time and a rate of return that considers the relative risk of achieving the cash flows, the time value of money, and other factors 
that a willing market participant would consider. Significant judgment is required to estimate the amount and timing of future 
cash flows and the relative risk of achieving those cash flows. 

Assumptions and estimates about future values and remaining useful lives are complex and often subjective. They can be 
affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such 
as changes in our business strategy and our internal forecasts.  

Contingent Consideration 

In connection with the acquisition of Omniome in the third quarter of 2021, we entered into an arrangement where we are 
obligated  to  pay  $200  million  in  cash  and  equity  dependent  upon  the  achievement  of  a  milestone  event  upon  the  first 
commercial shipment of products developed from our acquired sequencing technology. See Note 2. Business Acquisitions 
for further information.  

The contingent consideration liability was measured at fair value as of the acquisition date and is remeasured periodically at 
each reporting date, with changes in fair value recorded as change in fair value of contingent consideration in the statement 
of  operations.  The  initial  measurement  and  post-acquisition  remeasurement  require  estimates  and  assumptions  using  a 
scenario-based  method  that  considers  a  range  of  potential  outcomes  of  milestone  achievement  dates  and  assigned 
probabilities  of  occurrence  for  each  outcome.  Outcomes  are  discounted  to  present  value,  which  is  then  weighted  by  the 
probability of each scenario to determine the total fair value of the contingent consideration payment as of each reporting 
period.  This  method  requires  significant  management  judgment,  including  the  probability  of  achieving  certain  future 
milestones and discount rates. Future changes in our estimates could result in expenses or gains. Refer to Note 5. Financial 
Instruments for further discussion on valuation assumptions.

ITEM 7A.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

Interest Rate and Market Risk 

Our investment portfolio is exposed to market risk from changes in interest rates. The goals of our investment policy are 
preservation of capital, fulfillment of liquidity needs and fiduciary control of cash and cash equivalents and investments. We 
also seek to maximize income from our investments without assuming significant risk. To achieve our goals, we maintain a 
portfolio of cash equivalents and investments in a variety of securities of high credit quality. The securities in our investment 
portfolio are not leveraged, are classified as available for sale and are, due to their short-term nature, subject to minimal 
interest rate risk. The fair market value of our fixed rate securities may be adversely impacted by increases in interest rates 
while income earned may decline as a result of decreases in interest rates. A hypothetical 100 basis-point (one percentage 
point) increase or decrease in interest rates compared to rates on December 31, 2022 would have affected the fair value of 
our investment portfolio by approximately $2.5 million. 

We carry our convertible senior notes at the principal amount, less unamortized debt issuance costs, on our Consolidated 
Balance Sheets. Because the notes have a fixed annual interest rate of 1.50%, we do not have any economic interest rate 
exposure or financial statement risk associated with changes in interest rates. The fair value of the notes, however, may 
fluctuate when interest rates and the market price of our stock changes. See Note 7. Convertible Senior Notes in Part II, Item 
8 of this Annual Form 10-K for additional information.  

 Foreign Exchange Risk 

Our revenue, expense, and capital purchasing activities are primarily transacted in U.S. dollars; however, a portion of 
our operations is conducted in foreign currencies. As a result, we have foreign exchange exposures relating to non-U.S. dollar 
denominated cash flows and monetary assets and liabilities that are denominated in currencies other than U.S. dollars. The 
value of the amounts is exposed to changes in currency exchange rates from the time the transactions are originated, until 
the time the cash settlement is converted into U.S. dollars. Our foreign currency exposure is primarily concentrated in the 
Euro. A 10% strengthening of the U.S. dollar exchange rate against all currencies with which we have exposure, after taking 
into account offsetting positions at December 31, 2022 would have resulted in a $1.3 million decrease in the carrying amounts 
of those net assets. Actual gains and losses in the future may differ materially from these hypothetical gains and losses 
based on changes in the timing and amount of foreign currency exchange rate movements and our actual exposure. Our 
international operations are subject to risks typical of international operations, including, but not limited to, differing economic 
conditions, changes in political climate, differing tax structures, other regulations and restrictions, and foreign exchange rate 
volatility.

Report of Independent Registered Public Accounting Firm 

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Pacific Biosciences of California, Inc. (the Company) as 
of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive (loss) income, 
stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related 
notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial 
statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, 
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in 
conformity with U.S. generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in 
Internal Control–Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) and our report dated February 28, 2023, expressed an unqualified opinion thereon. 

Basis for Opinion 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion 
on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those 
risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide 
a reasonable basis for our opinion.  

Critical Audit Matter  

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements 
that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex 
judgments. The communication of critical audit matter does not alter in any way our opinion on the consolidated financial 
statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate 
opinion on the critical audit matter or on the account or disclosure to which it relates.

Description of the 
Matter  

Revenue recognition - Identification of performance obligations and 
allocation of contract consideration 

For the year ended December 31, 2022, the Company recognized revenue of 
$128.3 million, including $108.7 million of product revenue, which consists 
primarily of instrument sales and related consumables. As described in Note 
1 to the consolidated financial statements, instrument sales are generally 
sold in a bundled arrangement and commonly include the instrument, 
instrument accessories, training, and consumables. For bundled 
arrangements, the Company identifies a performance obligation for each 
promise to transfer, to the customer, a product or service that is distinct. The 
consideration for bundled arrangements is allocated between each 
performance obligation based on its individual standalone selling price, 
which is estimated by the Company, using historical sales data, as well as 
management judgment.  

The Company enters into, or periodically modifies, revenue contracts with 
non-standard terms, requiring management to evaluate whether these non-
standard terms represent a performance obligation. For example, the 
Company may offer specified discounts on current components of the 
bundled arrangements and on future purchase options, for which historical 
information may not be available. As part of the Company's identification of 
performance obligations and the resulting determination of the allocation of 
contract consideration, the Company considers if these specified discounts 
represent a material right when compared to the estimated standalone 
selling price and, therefore, a performance obligation to be included in the 
allocation of the contract value. 

Auditing management’s identification of the performance obligations and 
the resulting determination of the allocation of contract consideration in 
certain contracts involved a higher degree of judgment due to the subjective 
nature of identifying certain performance obligations and the related 
determination of standalone selling price when it is not based on historical 
information. 

How We Addressed the 
Matter in Our Audit  

We obtained an understanding, evaluated the design, and tested the 
operating effectiveness of the Company’s internal controls addressing 
management’s identification of performance obligations and allocation of 
contract consideration, including standalone selling price determination.  

Our audit procedures included, among others, reading executed contracts for 
a sample of arrangements and evaluating whether terms of the contracts 
(including specified discounts on current and future purchase options) 
resulted in additional performance obligations. Additionally, we tested the 
completeness and accuracy of the information used in management’s 
allocation of contract consideration, including the data incorporated in 
underlying calculations to determine standalone selling price. 

/s/ Ernst & Young LLP 

We have served as the Company’s auditor since 2011.

NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES 

Business Overview 

We are a life science technology company that is designing, developing, and manufacturing advanced sequencing solutions 
that  enable  scientists  and  clinical  researchers  to  improve  their  understanding  of  the  genome  and  ultimately,  resolve 
genetically complex problems. Our products and technology under development stem from two highly differentiated core 
technologies  focused  on  accuracy,  quality,  and  completeness,  which  include  our  existing  HiFi  long-read  sequencing

Basis of Presentation and Consolidation 

Our consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the 
United  States,  or  U.S.  GAAP,  as  set  forth  in  the  Financial  Accounting  Standards  Board,  or  FASB,  Accounting  Standards 
Codification,  or  ASC.  The  consolidated  financial  statements  include  the  accounts  of  Pacific  Biosciences  and  our  wholly 
owned subsidiaries. All intercompany transactions and balances have been eliminated. Certain prior period amounts have 
been reclassified to conform to the current period presentation. 

Use of Estimates  

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect 
the amounts reported in the financial statements and accompanying notes to the financial statements. On an ongoing basis, 
we evaluate our significant estimates including, but not limited to, the valuation of inventory, the determination of stand-alone 
selling prices for revenue recognition, the fair value of contingent consideration, the valuation of acquired intangible assets, 
the fair value of certain equity awards, the useful lives assigned to long-lived assets, the computation of provisions for income 
taxes,  the  borrowing  rate  used  in  calculating  the  operating  lease  right-of-use  assets  and  operating  lease  liabilities,  the 
probability associated with variable payments under partnership development agreements, and the valuations related to our 
convertible  senior  notes. While  the  extent  of  the  potential  impact  of  the  current  macroeconomic  conditions  and  ongoing 
COVID-19 pandemic on our business is highly uncertain, we considered information available related to assumptions and 
estimates used to determine the results reported and asset valuations as of December 31, 2022. Actual results could differ 
materially from these estimates.  

Functional Currency 

The U.S. dollar is the functional currency of our international operations.  We remeasure foreign subsidiaries monetary assets 
and liabilities to the U.S. dollar and record net gains or losses from remeasurement in other income, net, in the consolidated 
statement of operations and comprehensive (loss) income. 

Cash, Cash Equivalents, Restricted Cash, and Investments  

We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. Cash 
equivalents may be comprised of money market funds, certificates of deposit, commercial paper, corporate bonds and notes, 
and government agencies’ securities.  

We classify our investments in debt securities as available-for-sale and report the investments at fair value in current assets. 
We evaluate our available-for-sale investments in unrealized loss positions and assess whether the unrealized loss is credit-
related. Unrealized gains and losses that are not credit-related are recognized in accumulated other comprehensive (loss) 
income in stockholders’ equity. Realized gains and losses, expected credit losses, as well as interest income, on available-
for-sale securities are also reported in other income, net. The cost used in the determination of gains and losses of securities 
sold is based on the specific identification method. The cost of marketable securities is adjusted for the amortization of 
premiums and discounts to expected maturity. Premium and discount amortization is recorded in other income, net.

Our investment portfolio at any point in time contains investments in cash deposits, money market funds, commercial paper, 
corporate debt securities, and U.S. government and agency securities with high credit ratings. We have established guidelines 
regarding  diversification  and  maturities  of  investments  with  the  objectives  of  maintaining  safety  and  liquidity,  while 
maximizing yield. 

Restricted cash includes cash that is not readily available for use in the Company’s operating activities. Restricted cash is 
primarily comprised of cash pledged under letters of credit. 

Concentration and Other Risks  

Financial instruments that potentially subject us to credit risk consist principally of interest-bearing investments and trade 
receivables.  We  maintain  cash,  cash  equivalents,  and  investments  with  various  major  financial  institutions.  The 
counterparties  to  the  agreements  relating  to  our  investment  securities  consist  of  various  major  corporations,  financial 
institutions, municipalities, and government agencies of high credit standing. At December 31, 2022, most of our cash was 
deposited with U.S. financial institutions. Our investment policy generally restricts the amount of credit exposure to any one 
issuer. There is no limit to the percentage of the portfolio that may be maintained in securities issued by the U.S. Treasury 
and  U.S.  Government  Agencies,  or  other  securities  fully  backed  by  U.S.  Treasury  or  Government  agencies.  We  have  not 
experienced significant credit losses from financial institutions. 

Our trade receivables are derived from revenue to customers and distributors located in the United States and other countries. 
We perform credit evaluations of our customers’ financial condition and, generally, require no collateral from our customers. 
The allowance for credit losses is based on our assessment of the collectability of customer accounts. We regularly review 
our  trade  receivable  including  consideration  of  factors  such  as  historical  experience,  the  age  of  the  accounts  receivable 
balances, customer creditworthiness, customer industry, and current and forecasted economic conditions that may affect a 
customer’s ability to pay. We have not experienced any significant credit losses to date.  

Although we have historically not experienced significant credit losses, our exposure to credit losses may increase if our 
customers are adversely affected by changes in economic pressures or uncertainty associated with local or global economic 
recessions, disruption associated with the current COVID-19 pandemic, or other customer-specific factors.  

For the years ended December 31, 2022, 2021, and 2020, one customer accounted for approximately 12%, 13%, and 14% of 
our total revenue, respectively.  

As of December 31, 2022 and 2021, 57% and 53% of our accounts receivable were from domestic customers, respectively. 
As of December 31, 2022, one customer represented approximately 10% of our net accounts receivable. As of December 31, 
2021, no customer represented 10% or greater of our net accounts receivable.  

We currently purchase several key parts and components used in the manufacture of our products from a limited number of 
suppliers. Generally, we have been able to obtain an adequate supply of such parts and components but in certain instances 
have incurred additional costs to secure a supply of constrained material. An extended interruption in the supply of parts and 
components  currently  obtained  from  our  suppliers  could  adversely  affect  our  business  and  consolidated  financial 
statements.  

Inventory, Net  

Inventories are stated at the lower of cost or net realizable value on a first-in, first-out (“FIFO”) method. Adjustments to reduce 
the cost of inventory to its net realizable value, if required, are made for estimated excess or obsolete balances. Cost includes 
depreciation,  labor,  material,  and  overhead  costs,  including  product  and  process  technology  costs  while  determining  net 
realizable  value  of  inventories  involves  numerous  judgements,  including  projecting  future  average  selling  prices,  sales 
volumes, and costs to complete products in work in process inventories.   

We make inventory purchases and commitments to meet future shipment schedules based on forecasted demand for our 
products. The business environment in which we operate is subject to rapid changes in technology and customer demand. 
We  perform  a  detailed  assessment  of  inventory  each  period,  which  includes  a  review  of,  among  other  factors,  demand 
requirements,  product  life  cycle  and  development  plans,  component  cost  trends,  product  pricing,  product  expiration,  and 
quality issues. Based on our analysis, we record adjustments to inventory for potentially excess, obsolete, or impaired goods, 
when  appropriate,  to  report  inventory  at  net  realizable  value.  Inventory  adjustments  may  be  required  if  actual  demand, 
component costs, supplier arrangements, or product life cycles differ from our estimates. Any such adjustments would result 
in a charge to our results of operations. 

67 

 
Property and Equipment, Net  

Property and equipment are stated at cost, reviewed regularly for impairment, and depreciated over the estimated useful lives 
of the assets, using the straight-line method. Leasehold improvements are depreciated over the shorter of the lease term or 
the  estimated  useful  life  of  the  related  asset.  Major  improvements  are  capitalized,  while  maintenance  and  repairs  are 
expensed as incurred. Transfers of assets between property and equipment, net, and inventory are transferred at standard 
cost and recognized at carrying value. 

Estimated useful lives of the major classes of property and equipment are as follows: 

Leasehold improvements 
Lab equipment 
Computer equipment 
Computer software 
Furniture and fixtures 

Operating Leases  

Estimated Useful Lives 
3 to 10 years 
3 to 5 years 
3 to 5 years 
3 years 
3 to 5 years 

We record operating lease right-of-use assets and liabilities on our Consolidated Balance Sheets for all leases with a term of 
more than 12 months. The operating lease right-of-use assets and liabilities are calculated as the present value of remaining 
minimum lease payments over the remaining lease term using our estimated secured incremental borrowing rates at the 
commencement date. Lease payments included in the measurement of the lease liability comprise the fixed rent per the term 
of the Lease. Operating lease expense is recognized on a straight-line basis over the lease term, with variable lease payments, 
such as common area maintenance fees, recognized in the period incurred.  

Business Combinations 

Under the acquisition method of accounting, we allocate the fair value of the total consideration transferred to the tangible 
and  identifiable  intangible  assets  acquired  and  liabilities  assumed  based  on  their  estimated  fair  values  on  the  date  of 
acquisition. These valuations require us to make estimates and assumptions, especially with respect to intangible assets. 
We record the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, 
as  goodwill.  Costs  that  we  incur  to  complete  the  business  combination,  such  as  legal  and  other  professional  fees,  are 
expensed as they are incurred. 

In connection with certain acquisitions, contingent consideration can be earned by the sellers upon completion of certain 
future performance milestones. In these cases, a liability is recorded on the acquisition date for an estimate of the acquisition 
date  fair  value  of  the  contingent  consideration.  These  estimates  require  significant  management  judgment,  including 
probabilities of achieving certain future milestones. Changes in the fair value of the contingent consideration subsequent to 
the acquisition date are recognized in operating expense in our consolidated statements of operations and comprehensive 
(loss) income. 

If  the  initial  accounting  for  a  business  combination  is  incomplete  by  the  end  of  a  reporting  period  that  falls  within  the 
measurement period, we report provisional amounts in our financial statements. During the measurement period, we adjust 
the  provisional  amounts  recognized  at  the  acquisition  date  to  reflect  new  information  obtained  about  facts  and 
circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts 
recognized as of that date. We record these adjustments to the provisional amounts with a corresponding offset to goodwill. 
Any adjustments identified after the measurement period are recorded in the consolidated statements of income. 

Goodwill, Intangible Assets, and Other Long-Lived Assets 

Assets acquired, including intangible assets and capitalized in-process research and development (“IPR&D”), and liabilities 
assumed are measured at fair value as of the acquisition date. Goodwill, which has an indefinite useful life, represents the 
excess of cost over fair value of the net assets acquired. Intangible assets acquired in a business combination that are used 
for  IPR&D  activities  are  considered  indefinite  lived  until  the  completion  or  abandonment  of  the  associated  research  and 
development efforts. Upon reaching the end of the relevant research and development project (i.e., upon commercialization), 
the IPR&D asset is amortized over its estimated useful life. If the relevant research and development project is abandoned, 
the IPR&D asset is expensed in the period of abandonment. 

Goodwill  and  IPR&D  are  not  amortized;  however,  they  are  reviewed  for  impairment  at  least  annually.  We  perform  annual 
impairment testing of goodwill in the second quarter of each year and IPR&D in the fourth quarter of each year, or more 
frequently if indicators of potential impairment exist. 

68 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We perform our goodwill impairment analysis at the reporting unit level. We have one reporting unit, which aligns with our 
reporting  structure  and  availability  of  discrete  financial  information.  During  the  goodwill  impairment  review,  we  assess 
qualitative factors to determine whether it is more likely than not that the fair values of our reporting unit is less than the 
carrying  amount,  including  goodwill.  The  qualitative  factors  include,  but  are  not  limited  to,  macroeconomic  conditions, 
industry and market considerations, and our overall financial performance. If, after assessing the totality of these qualitative 
factors, we determine that it is not more likely than not that the fair value of our reporting unit is less than the carrying amount, 
then  no  additional  assessment  is  deemed  necessary.  Otherwise,  we  proceed  to  compare  the  estimated  fair  value  of  the 
reporting unit with the carrying value, including goodwill. If the carrying amount of the reporting unit exceeds the fair value, 
we record an impairment loss based on the difference. We may elect to bypass the qualitative assessment in a period and 
proceed to perform the quantitative goodwill impairment test. 

During the IPR&D impairment review, we assess qualitative factors to determine whether it is more likely than not that the 
fair value of the IPR&D is less than the carrying amount. The qualitative factors include, but are not limited to, macroeconomic 
conditions, industry-specific conditions, and company-specific conditions. If, after assessing the totality of these qualitative 
factors, we determine that it is not more likely than not that the fair value of the IPR&D is less than the carrying amount, then 
no additional assessment is deemed necessary. Otherwise, we proceed to compare the estimated fair value of the IPR&D 
with the carrying value. If the carrying amount of the IPR&D exceeds the fair value, we record an impairment loss based on 
the  difference.  We  may  elect  to  bypass  the  qualitative  assessment  in  a  period  and  proceed  to  perform  the  quantitative 
impairment test. 

Finite-lived intangibles assets include our acquired developed technology and customer relationships. We capitalize finite-
lived intangibles assets and generally amortize them on a straight-line basis over the estimated useful lives. We regularly 
review the carrying amount and useful lives of our finite-lived assets to determine whether indicators of impairment may exist 
which warrant adjustments to carrying values or estimated useful lives. If indicators of impairment exist, an impairment test 
is performed to assess the recoverability of the affected assets by determining whether the carrying amount of such assets 
exceeds the undiscounted expected future cash flows. If the affected assets are not recoverable, we estimate the fair value 
of  the  assets  and  record  an  impairment  loss  if  the  carrying  value of  the  assets  exceeds  the  fair  value.  Factors  that may 
indicate potential impairment include a significant decline in our stock price and market capitalization compared to the net 
book value, significant changes in the ability of a particular asset to generate positive cash flows for our strategic business 
objectives, and the pattern of utilization of a particular asset. 

Revenue Recognition  

Our revenue is generated primarily from the sale of products and services. Product revenue primarily consists of sales of our 
instruments  and  related  consumables;  service  and  other  revenue  consist  primarily  of  revenue  earned  from  product 
maintenance agreements. 

We account for a contract with a customer when there is a legally enforceable contract between us and the customer, the 
rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is 
probable.  Revenues  are  recognized  when  control  of  the  promised  goods,  or  services  is  transferred  to  our  customers,  or 
services are performed, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods 
or services.  

Our  instrument  sales  are  generally  sold  in  a  bundled  arrangement  and  commonly  include  the  instrument,  instrument 
accessories, training, and consumables. For such bundled arrangements, we account for individual products and services 
separately if they are distinct, that is, if a product or service is separately identifiable from other items in the bundled package 
and if a customer can benefit from it on its own or with other resources that are readily available to the customer. Installation 
services are considered distinct from the instrument. Therefore, instrument revenue is recognized upon transfer of control 
of the asset to the customer, which is generally upon delivery for sales made to our non-distributor customers and upon 
shipment for sales made to our distributor customers.  

The consideration for bundled arrangements is allocated between separate performance obligations based on their individual 
standalone selling price. We determine the best estimate of standalone selling price using average selling prices over a 12-
month  period  combined  with  an  assessment  of  current  market  conditions.  If  the  standalone  selling  price  is  not  directly 
observable,  we  rely  on  estimates  by  considering  multiple  factors  including,  but  not  limited  to,  overall  market  conditions, 
including  geographic  or  regional  specific  factors,  internal  costs,  profit  objectives,  pricing  practices,  and  other  observable 
inputs. We recognize revenues as performance obligations are satisfied by transferring control of the product or service to 
the customer or over the term of a product maintenance agreement with a customer. Our revenue arrangements generally 
do not provide a right of return. Revenue is recorded net of discounts and sales taxes collected on behalf of governmental 
authorities. 

Certain  of  our  agreements  provide  options  to  customers  which  can  be  exercised  at  a  future  date,  such  as  the  option  to 
purchase our product at discounted prices, among others. In accounting for customer options, we determine whether an 
option is a material right and this requires us to exercise significant judgment. If a contract provides the customer an option 

69 

 
to  acquire  additional  goods  or  services  at  a  discount  that  exceeds  the  range  of  discounts  that  we  typically  give  for  that 
product or service for the same class of customer, or if the option provides the customer certain additional goods or services 
for free, the option may be considered a material right. If the contract gives the customer the option to acquire additional 
goods or services at their normal standalone selling prices, we would likely determine that the option is not a material right 
and, therefore, account for it as a separate performance obligation when the customer exercises the option. If the standalone 
selling  price  of  the  option  is  not  directly  observable,  an  estimated  standalone  selling  price  is  utilized  which  considers 
adjustments for discounts that the customer could receive without exercising the option and the likelihood that the option 
will be exercised. We may also utilize the alternative approach to estimate the standalone selling price, available pursuant to 
the applicable accounting guidance, to the extent we conclude the applicable criteria for using the alternative approach has 
been met. We update the transaction price for expected consideration, subject to constraint, each reporting period if our 
estimate of future goods to be ordered by customers change.  

Additionally, we generally provide a one-year warranty on instruments. We accrue the cost of the assurance warranty when 
revenue  of  the  instrument  is  recognized.  Employee  sales  commissions  are  generally  recorded  as  selling,  general,  and 
administrative expense when incurred as the amortization period for such costs, if capitalized, would have been one year or 
less. 

Cost of Revenue 

Cost  of  revenue  reflects  the  direct  cost  of  product  components,  third-party  manufacturing  services,  and  our  internal 
manufacturing overhead and customer service infrastructure costs incurred to produce, deliver, maintain, and support our 
instruments, consumables, and services. 

Manufacturing overhead is predominantly comprised of labor and facility costs. We capitalize manufacturing overhead into 
inventory based on a standard cost model that approximates actual costs.  

Service costs include the direct costs of components used in support, repair and maintenance of customer instruments as 
well as the cost of personnel, materials, shipping and support infrastructure necessary to support our installed customer 
base.  

Research and Development  

Research and development expense consists primarily of expenses for personnel engaged in the development of our core 
technology, the design and development of our future products and current product enhancements. These expenses also 
include prototype-related expenditures, development equipment and supplies, partner development costs, facilities costs, 
and other related overhead. We expense research and development costs during the period in which the costs are incurred. 
We defer and capitalize non-refundable advance payments made for research and development activities until the related 
goods are received or the related services are rendered. 

Credit Losses 

Trade accounts receivable 

The allowance for credit losses is based on our assessment of the collectability of customer accounts. We regularly review 
the  allowance  by  considering  factors  such  as  the  age  of  the  accounts  receivable  balances,  customer  creditworthiness, 
customer industry, and current and forecasted economic conditions that may affect a customer’s ability to pay. Credit loss 
expense was immaterial for the years ended December 31, 2022 and 2021. 

Available-for-sale debt securities 

Our investment portfolio at any point in time contains investments in cash deposits, money market funds, commercial paper, 
corporate  debt  securities  and  U.S.  government  and  agency  securities.  We  regularly  assess  whether  our  securities  in  an 
unrealized loss position are credit related. The credit-related portion of unrealized losses, and any subsequent improvements, 
are  recorded  in  interest  income.  Unrealized  losses  that  are  not  credit  related  are  included  in  accumulated  other 
comprehensive income. The unrealized losses on our investments are mainly attributable to government securities, including 
U.S. government and U.S. agency bond securities, impacted by movements in market rates and not due to issuer credit risk. 
We have the ability to hold and do not intend to sell the investments in unrealized loss positions before the recovery of their 
amortized cost bases. 

Although we have historically not experienced significant credit losses, our exposure to credit losses may increase if our 
customers are adversely affected by changes in economic pressures or uncertainty associated with local or global economic 
recessions, disruptions associated with the evolution of the COVID-19 pandemic, or other customer-specific factors.  

70 

 
Income Taxes  

We account for income taxes under the asset and liability method, which requires, among other things, that deferred income 
taxes be provided for temporary differences between the tax bases of our assets and liabilities and the amounts reported in 
the financial statements. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses 
and  research  and  development  credit  carryforwards.  The  effect  of  a  change  in  tax  rates  on  the  deferred  tax  assets  and 
liabilities  is  recognized  in  the  provision  for  income  taxes  in  the  period  that  includes  the  enactment  date.  A  full  valuation 
allowance is provided against our net deferred tax assets as it is more likely than not that the deferred tax assets will not be 
fully realized.  

We regularly review our positions taken relative to income taxes. To the extent our tax positions are more likely than not going 
to result in additional taxes, we accrue the estimated amount of tax related to such uncertain positions.  

Share-based Compensation  

We  account  for  share-based  payments  using  a  fair-value  based  method  for  costs  related  to  all  share-based  payments, 
including  stock  options,  restricted  stock  units,  and  stock  issued  under  our  employee  stock  purchase  plan  (“ESPP”).  We 
estimate the fair value of share-based payment awards that are stock options and issued under our ESPP on the date of grant 
using an option-pricing model. See Note 10. Stockholders’ Equity for further information regarding share-based compensation. 

Other Comprehensive (Loss) Income 

Other comprehensive (loss) income is comprised of unrealized (losses) gains on our investment securities.  

Shipping and Handling 

Costs related to shipping and handling are included in cost of revenues for all periods presented. 

Earnings per Share 

Basic net (loss) income per share is computed by dividing net (loss) income by the weighted-average number of shares of 
common stock outstanding during the period. Diluted net (loss) income per share is computed using the weighted-average 
number  of  shares  of  common  stock  outstanding  and  potential  shares  assuming  the  dilutive  effect  of  outstanding  stock 
options, restricted stock units, and common stock issuable pursuant to our ESPP, using the treasury stock method. 

Recent Accounting Pronouncements 

Recently Adopted Accounting Standards 

There are no accounting standards updates (“ASUs”) that have been recently adopted and are applicable to our consolidated 
financial statements. 

Accounting Pronouncements Pending Adoption 

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and 
Contract Liabilities from Contracts with Customers. This ASU provides specific guidance on how to recognize contract assets 
and contract liabilities related to revenue contracts with customers acquired in a business combination. This amendment 
improves comparability for both the recognition and measurement of acquired revenue contracts with customers at the date 
of  and  after a  business  combination. This  authoritative guidance  will  be  effective  for  us  in  the  first  quarter  of 2023.  The 
adoption of this guidance is not expected to have a material effect on our consolidated financial statements. 

NOTE 2. BUSINESS ACQUISITIONS 

Omniome, Inc. 

On September 20, 2021, we completed our acquisition of Omniome, Inc. (“Omniome”), a San Diego-based company, to obtain 
their proprietary short-read DNA sequencing platform capable of delivering high accuracy (the “Omniome acquisition”).  

In connection with the Omniome acquisition, all outstanding equity securities of Omniome were cancelled in exchange for 
approximately  $315.7  million  in  cash,  8,911,580  shares  of  our  common  stock  with  a  fair  value  of  $249.4  million  and 
contingent  consideration  with  a  fair  value  of  $168.6  million.  The  fair  value  of  the  8,911,580  common  shares  issued  was 
determined based on the closing market price of PacBio’s common shares on the acquisition date. 

In addition, approximately $18.9 million, comprised of $7.4 million of cash, 226,811 shares of our common stock with a fair 
value of $6.3 million, and $5.2 million related to contingent consideration, was accounted for as a one-time post acquisition 
share-based compensation expense. This share-based compensation expense was due to accelerated vesting of Omniome 
stock awards in connection with the acquisition. 

71 

 
 
In connection with the acquisition the contingent consideration of $200 million (composed of $100 million in cash and $100 
million in shares of our common stock) is due upon the achievement of a milestone, defined as the first commercial shipment 
to a customer of a nucleotide sequencing platform, comprising both an instrument and related consumables, that utilizes 
SBB technology. The number of shares of stock to be issued will be determined using the volume-weighted average of the 
trading prices of our common stock for the twenty trading days ending with and including the trading day that is two days 
immediately prior to the achievement of the milestone. Of the $100 million in shares of our common stock to be issued as 
part of the milestone, $4.1 million was attributable to stock options issued by PacBio in replacement of Omniome’s unvested 
options as part of the transaction. Upon achievement of the milestone, shares will be issued not in excess of an amount 
equal to 19.9% of our outstanding shares of common stock on the date of closing (prior to the issuance of any shares issued 
in connection with the transaction or the related private placement), less 11,500,000 shares. 

The contingent consideration is accounted for as a liability at fair value, with changes during each reporting period recognized 
in  our  Consolidated  Statements  of  Operations  and  Comprehensive  Loss.  The  fair  value  of  the  contingent  consideration 
liability is calculated, with the assistance from a third-party valuation firm, using a scenario-based method that considers a 
range of possible outcomes and their assigned probabilities of occurrence. The potential outcomes are discounted to present 
value at a discount rate equal to the sum of the term-matched risk-free-interest rate plus PacBio’s credit spread.  

Total consideration transferred for the acquisition is as follows (in thousands):

Fair value of share consideration

The  acquisition  was  accounted  for  as  a  business  combination  and,  accordingly,  the  total  fair  value  of  the  consideration 
transferred was allocated to the tangible and intangible assets acquired and liabilities assumed based on their fair values on 
the acquisition date. As of December 31, 2021, the major classes of assets and liabilities to which we have allocated the total 
fair value of the consideration transferred were as follows (in thousands): 

Cash and cash equivalents 
Property and equipment, net  
Operating lease right-of-use assets, net  
In-process research and development ("IPR&D") 
Goodwill 
Other assets

During  the  year  ended  December  31,  2021,  we  recorded  a  measurement  period  adjustment  of  $1.6  million  to  decrease 
goodwill and a corresponding $0.4 million to decrease the deferred tax liability on the Consolidated Balance Sheet, and a $1.2 
million decrease to our benefit from income taxes on the Consolidated Statements of Operations and Comprehensive (Loss) 
Income. The measurement period adjustment was due to new information that became available to us upon the completion 
of the IRC Section 382 Tax Study, where we identified additional net operating losses that are available to us from acquired 
assets. Refer to Note 9 – Income Taxes, in Part II, Item 8 of the Annual Report on Form 10-K for the year ended December 31, 
2021 for more information. There were no measurement period adjustments recorded in the year ended December 31, 2022. 

The goodwill recognized was primarily attributable to the assembled workforce and synergies that are expected to occur 
from the integration of Omniome and is not deductible for income tax purposes.  

We  incurred  costs  related  to  the  Omniome  acquisition  of  approximately  $12.0  million  during  the  twelve  months  ended 
December  31,  2021,  which  are  included  in  merger-related  costs  on  the  Consolidated  Statement  of  Operations  and 
Comprehensive (Loss) Income. No significant merger-related costs were incurred during the twelve months ended December 
31, 2022. 

The following unaudited pro forma financial information presents combined results of operations for each of the periods 
presented as if Omniome had been acquired as of the beginning of 2020, giving effect on a pro forma basis to the purchase 
accounting  adjustments  such  as  $12.0  million  of  PacBio  acquisition-related  costs,  $18.9  million  of  share-based 
compensation expense related to acceleration of certain Omniome stock options not attributable to pre-combination service, 
and a $91.0 million one-time income tax benefit from the reduction of our deferred tax asset valuation allowance resulting 
from the Omniome acquisition, as well as a pro forma adjustment to reflect $16.7 million of Omniome’s acquisition-related 
costs.

Our  consolidated  financial  statements  include  the  results  of  operations  for  Omniome  beginning  September  20,  2021. 
Revenues of $0 and a net loss of $15.6 million from the acquired Omniome business have been included in our Consolidated 
Statement of Operations and Comprehensive (Loss) Income for the twelve months ended December 31, 2021. 

Circulomics, Inc. 

On  July  20,  2021,  we  acquired  Circulomics  Inc.  (“Circulomics”),  a  Maryland-based  biotechnology  company  focused  on 
delivering highly differentiated sample preparation products that enable genomic workflows (the “Circulomics acquisition”).  

We paid $29.5 million in cash in exchange for all outstanding shares of common stock of Circulomics. We allocated the 
consideration transferred to the identifiable assets acquired and liabilities assumed based on their respective fair values at 
the  date  of  the  completion  of  the  Circulomics  acquisition.  The  major  classes  of  assets  and  liabilities  to  which  we  have 
allocated the total fair value of the consideration transferred were as follows (in thousands): 

Cash and cash equivalents 
Property and equipment, net  
Intangible assets

The excess of the value of consideration paid over the aggregate fair value of those net assets has been recorded as goodwill. 
We  recognized  goodwill  of  $19.3  million,  which  is  primarily  attributable  to  the  synergies  expected  from  capabilities  in 
extraction and sample preparation and is not deductible for income tax purposes. We recorded $11.4 million for the fair value 
of acquired intangible assets, which consists of developed technology and customer relationships. 

NOTE 3. INVITAE COLLABORATION 

On June 24, 2022, we entered into an Amended and Restated Development and Commercialization Agreement (the “Amended 
and Restated Agreement”) with Invitae Corporation (“Invitae”). The Amended and Restated Agreement amended and restated 
the existing Development and Commercialization Agreement, effective as of January 12, 2021, as amended by Amendment 
No.  1  to  Development  and  Commercialization  Agreement,  entered  into  on  June  3,  2021,  by  and  between  us  and  Invitae 
(together, the “Original Agreement”). Unless otherwise agreed in writing or terminated in accordance with the Amended and 
Restated Agreement, the term of the Amended and Restated Agreement shall continue until June 30, 2028 (“Term”).  

Pursuant to the Original Agreement, Invitae provided certain funding to us to develop products relating to production-scale 
high-throughput sequencing (“Program Products”). If Program Products were to become commercially available, Invitae had 
the right to purchase the Program Products at preferred pricing. 

Under  the  Amended  and  Restated  Agreement,  we  will  continue  to  receive  feedback,  input  and  insight  from  Invitae  in 
connection with the intended development of our new sequencing systems; however, such feedback will not be contractually 
required, and Invitae has no contractual right to participate in decisions regarding the development program for such new 
sequencing systems. Our development plans for such new sequencing systems will be at our discretion and pursuant to our 
own internal processes and programs. Invitae will not be contractually obligated to reimburse us for development costs under 
the  Amended  and  Restated  Agreement.  There  can  be  no  assurances  that  the  in-development  sequencing  systems  will 
continue to be developed, be successfully developed or become available for commercial sale. 

In consideration of the non-refundable payments received from Invitae pursuant to the Original Agreement of $23.5 million, 
we will provide Invitae with credits in connection with Invitae’s anticipated purchase of certain currently available and in-
development  sequencing  systems  (instruments  and  consumables).  The  credits  will  expire  on  June  30,  2025  (“Credit 
Expiration Date”). Subject to certain conditions, Invitae will also be entitled to most favored pricing for the Company’s Sequel 
IIe systems and certain in-development systems through the Term.  

73 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We and Invitae may terminate the Amended and Restated Agreement if the other party remains in material breach of the 
Amended and Restated Agreement following a cure period to remedy the material breach. 

The  Amended  and  Restated  Agreement  is  deemed  a  contract  modification  and  accounted  for  on  a  prospective  basis  in 
accordance with ASC Topic 606. We will recognize proportionate amounts of the transaction price, including payments made 
by Invitae to us pursuant to the Original Agreement, in revenue as the remaining performance obligations are satisfied, which 
is  when  Invitae  places  purchase  orders  for  certain  currently  available  and  in-development  sequencing  platforms  and  the 
associated goods are delivered. Any remaining unused credits will be recognized when they expire. 

During the year ended December 31, 2022, Invitae purchased certain currently available instruments, for which $3.7 million 
of revenue was recognized as product revenue on the Consolidated Statements of Operations and Comprehensive (Loss) 
Income under the terms of the Amended and Restated Agreement. 

As of December 31, 2022, $21.4 million of deferred revenue, current, is recorded on the Consolidated Balance Sheet relating 
to all future performance obligations under the Amended and Restated Agreement. 

NOTE 4. TERMINATION OF MERGER WITH ILLUMINA 

On November 1, 2018, we entered into an Agreement and Plan of Merger (as amended, the “Illumina Merger Agreement”) 
with Illumina, Inc. (“Illumina”) and FC Ops Corp., a wholly owned subsidiary of Illumina (“Illumina Merger Sub”). On January 2, 
2020, we, Illumina and Illumina Merger Sub, entered into an agreement to terminate the Merger Agreement (the “Termination 
Agreement”).  

Continuation Advances from Illumina 

As part of the Termination Agreement, Illumina paid us cash payments (“Continuation Advances”) totaling $52 million. Up to 
the full $52.0 million of Continuation Advances paid to us were repayable without interest to Illumina if, within two years of 
March 31, 2020, we entered into, or consummated a Change of Control Transaction or raised at least $100 million in a single 
equity or debt financing (that may have multiple closings), with the amount repayable dependent on the amount raised by us.  

Resulting from the issuance and sale of $900 million of 1.50% Convertible Senior Notes due February 15, 2028, $52.0 million 
of Continuation Advances were paid without interest to Illumina in February 2021 and recorded a non-operating expense in 
the Consolidated Statements of Operations and Comprehensive (Loss) Income for the year ended December 31, 2021. 

NOTE 5. FINANCIAL INSTRUMENTS  

Fair Value of Financial Instruments 

Fair value is the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction 
between market participants at the measurement date.  

The fair value hierarchy established under GAAP requires an entity to maximize the use of observable inputs and minimize 
the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value 
are as follows:  

•  Level 1: quoted prices in active markets for identical assets or liabilities; 
•  Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active 
markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are 
not active, or other inputs that are observable or can be corroborated by observable market data for substantially the 
full term of the assets or liabilities; and 

•  Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value 

of the assets or liabilities. 

We consider an active market as one in which transactions for the asset or liability occurs with sufficient frequency and 
volume to provide pricing information on an ongoing basis. Conversely, we view an inactive market as one in which there are 
few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or 
among market makers. Where appropriate, our non-performance risk, or that of our counterparty, is considered in determining 
the fair values of liabilities and assets, respectively.  

74 

 
We classify our cash deposits and money market funds within Level 1 of the fair value hierarchy because they are valued 
using bank balances or quoted market prices. We classify our investments as Level 2 instruments based on market pricing 
and other observable inputs. We did not classify any of our investments within Level 3 of the fair value hierarchy. 

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level input that is significant 
to the fair value measurement. Our assessment of the significance of a particular input to the entire fair value measurement 
requires management to make judgments and consider factors specific to the asset or liability.  

The carrying amount of our accounts receivable, prepaid expenses, other current assets, accounts payable, accrued expenses 
and other liabilities, current, approximate fair value due to their short maturities.  

Assets and Liabilities Measured at Fair Value on a Recurring Basis 

The following table sets forth the fair value of our financial assets and liabilities that were measured on a recurring basis as 
of December 31, 2022 and December 31, 2021, respectively:

We classify contingent consideration, which was incurred in connection with the acquisition of Omniome, within Level 3 as 
factors used to develop the estimate of fair value include unobservable inputs that are not supported by market activity and 
are significant to the fair value.  

We  estimate  the  fair  value  of  the  contingent  consideration  liability  by  discounting  the  probability-weighted  outcomes  to 
present  value  using  an  estimate  of  our  borrowing  rate  and  the  risk-free  rate.  The  potential  outcomes  of  milestone 
achievement dates are within the period from June 30, 2023 to June 30, 2025. A decrease in the probability of an earlier 
scenario within this range would result in a decrease in the fair value of the liability. The discount rates used are the sum of 
the U.S. risk-free rate and the estimated subordinated credit spread for B- and B credit rating, which ranges from 10.1% to 
10.5%.  Changes  in  our  estimated  subordinated  credit  spread  can  result  in  changes  in  the  fair  value  of  the  contingent 
consideration liability, where a lower credit spread may result in an increased liability valuation. 

Changes in the estimated fair value of the contingent consideration liability for the year ended December 31, 2022 were as 
follows:

Construction in progress consists of capitalizable costs that have been incurred for the construction of long-lived assets, and 
is primarily comprised of amounts that will be classified as lab equipment.  

Depreciation expense during the years ended December 31, 2022, 2021, and 2020 was $9.5 million, $7.2 million, and $6.4 
million, respectively.  

Goodwill and intangible Assets 

Goodwill 

As of December 31, 2022 and 2021, the goodwill balance was $410.0 million. Goodwill is reviewed for impairment at least 
annually  during  the  second  quarter,  or  more  frequently  if  an  event  occurs  indicating  the  potential  for  impairment.  We 
performed our annual assessment for goodwill impairment in the second quarter of 2022, noting no impairment. 

Acquired Intangible Assets 

Intangible assets include acquired IPR&D of $400 million as a result of the Omniome acquisition in September 2021. As of 
December 31, 2022, the research and development project had not been completed or abandoned and, therefore, the IPR&D 
intangible  asset  is  not  currently  subject  to  amortization.  IPR&D  is  reviewed  for  impairment  at  least  annually,  or  more 
frequently  if  an  event  occurs  indicating  the  potential  for  impairment.  We  performed  our  annual  assessment  for  IPR&D 
impairment in the fourth quarter of 2022, noting no impairment. 

In addition to IPR&D, we had the following acquired definite-lived intangible assets as of December 31, 2022 (in thousands,

We generally provide a one-year warranty on instruments. In addition, we provide a limited warranty on consumables. At the 
time revenue is recognized, an accrual is established for estimated warranty costs based on historical experience as well as 
anticipated product performance. We periodically review the warranty reserve for adequacy and adjust the warranty accrual, 
if necessary, based on actual experience and estimated costs to be incurred. Warranty expense is recorded as a component 
of cost of product revenue. There were no material changes in estimates for the periods presented below.

As of December 31, 2022, we had a total of $32.3 million of deferred revenue, $30.5 million of which was recorded as deferred 
revenue, current and primarily relates to future performance obligations under the Amended and Restated Agreement with 
Invitae as described in Note 3. Invitae Collaboration. The deferred revenue, non-current balance of $1.8 million primarily relates 
to deferred service contract revenues and is scheduled to be recognized in the next 6 years. Revenue recorded in the year 
ended December  31,  2022  includes $13.0  million  of  previously  deferred  revenue  that  was  included  in  deferred  revenue, 
current as of December 31, 2021. 

Term Loans 

In connection with the acquisition of Omniome, we acquired $1.3 million in short-term debt and $3.0 million in long-term debt 
relating to a term loan facility that Omniome obtained in April 2020. Borrowings on the term loan facility were used to fund 
Omniome’s purchases of equipment, which serves as collateral. Each term loan has a term of 43 months and bears a fixed 
interest rate of approximately 17% annually. The fee for the elective option to prepay all, but not less than all, of the borrowed 
amounts at any time after the 24th month and before the 43rd month after the commencement date, is 4% of the outstanding 
loan balance. Payments are made in equal monthly installments including principal and interest.  

As of December 31, 2022, the carrying value of term loans outstanding was $2.3 million. The related long-term portion of 
$0.5 million was recorded as part of other liabilities, non-current and the short-term portion of $1.8 million was recorded as 
part of other liabilities, current on the Consolidated Balance Sheet. The interest expense was $0.6 million for the year ended 
December  31,  2022,  which  was  included  as  part  of  interest  expense  in  the  Consolidated  Statement  of  Operations  and 
Comprehensive (Loss) Income.

On  February 9,  2021,  we  entered  into  an  investment  agreement  (the  “Investment  Agreement”)  with  SB  Northstar  LP  (the 
“Purchaser”), a subsidiary of SoftBank Group Corp., relating to the issuance and sale to the Purchaser of $900  million in 
aggregate principal amount of our 1.50% Convertible Senior Notes (the “Notes”). The Notes were issued on February 16, 
2021. 

The  Notes  are  governed  by  an  indenture  (the  “Indenture”)  between  the  Company  and  U.S.  Bank  National  Association,  as 
trustee. The Notes bear interest at a rate of 1.50% per annum. Interest on the Notes is payable semi-annually in arrears on 
February 15 and August 15 and commenced on August 15, 2021. The Notes will mature on February 15, 2028, subject to 
earlier conversion, redemption, or repurchase. 

The Notes are convertible at the option of the holder at any time until the second scheduled trading day prior to the maturity 
date, including in connection with a redemption by the Company. The Notes are convertible into shares of our common stock 
based on an initial conversion rate of 22.9885 shares of common stock per $1,000 principal amount of the Notes (which is 
equal to an initial conversion price of $43.50 per share), in each case subject to customary anti-dilution and other adjustments 
as  a  result  of  certain  extraordinary  transactions.  Upon  conversion  of  the  Notes,  we  may  elect  to  settle  such  conversion 
obligation in shares, cash or a combination of shares and cash. 

On or after February 20, 2026, the Notes will be redeemable by the Company in the event that the closing sale price of our 
common stock has been at least 150% of the conversion price then in effect for at least 20 trading days (whether or not 
consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and 
including, the trading day immediately preceding the date on which we provide the redemption notice at a redemption price 
of 100% of the principal amount of such Notes, plus accrued and unpaid interest up to, but excluding, the redemption date. 

With certain exceptions, upon a change of control of the Company or the failure of our common stock to be listed on certain 
stock  exchanges  (a  “Fundamental  Change”),  the  holders  of  the  Notes  may  require  that  we  repurchase  all  or  part  of  the 
principal amount of the Notes at a purchase price of par plus unpaid interest up to, but excluding, the maturity date. 

The Indenture includes customary “events of default,” which may result in the acceleration of the maturity of the Notes under 
the Indenture. The Indenture also includes customary covenants for convertible notes of this type. 

To the extent we elect, the sole remedy for an event of default relating to our failure to comply with certain of our reporting 
obligations shall, for the first 360 calendar days after the occurrence of such an event of default, consist exclusively of the 
right to receive additional interest on the Notes at a rate equal to (i) 0.25% per annum of the principal amount of the Notes 
outstanding for each day during the first 180 calendar days of the 360-day period after the occurrence of such an event of 
default during which such event of default is continuing (or, if earlier, the date on which such event of default is cured or 
waived) and (ii) 0.50% per annum of the principal amount of the Notes outstanding for each day from, and including, the 
181st calendar day to, and including, the 360th calendar day after the occurrence of such an event of default during which 
such event of default is continuing (or, if earlier, the date on which such event of default is cured or waived as provided for in 
the Indenture). On the 361st day after such event of default (if the event of default relating to our failure to comply with its 
obligations is not cured or waived prior to such 361st day), the Notes shall be subject to acceleration as provided for in the 
Indenture.

The Notes are accounted for in accordance with the authoritative guidance for convertible debt instruments that may be 
settled in cash upon conversion. Under ASU 2020-06, the guidance requires that debt with an embedded conversion feature 
is accounted for in its entirety as a liability and no portion of the proceeds from the issuance of the convertible debt instrument 
is  accounted  for  as  attributable  to  the  conversion  feature  unless  the  conversion  feature  is  required  to  be  accounted  for 
separately as an embedded derivative or the conversion feature results in a substantial premium. The conversion feature of 
the Notes is not accounted for as an embedded derivative because it is considered to be indexed to our common stock, and 
the Notes were not issued at a premium; therefore, the Notes are accounted for in their entirety as a liability. Because we may 
elect to settle any conversions entirely in shares, and because settlement in shares is the default settlement method, the 
liability is classified as non-current.  

The requirement to repurchase the Notes including unpaid interest to the maturity date in the event of a Fundamental Change 
is considered a put option for certain periods requiring bifurcation under ASC 815 – Derivatives and Hedging. However, given 
the low probability of a Fundamental Change occurring during the applicable periods, the value of the embedded derivative 
is immaterial. 

The additional interest feature in the event of our failure to comply with certain reporting obligations is also considered an 
embedded derivative requiring bifurcation under ASC 815. However, due to the nature and terms of the reporting obligations, 
the value of the embedded derivative is immaterial. 

We incurred issuance costs related to the Notes of approximately $4.5 million, which were recorded as debt issuance cost 
and are presented as a reduction to the Notes on our Consolidated Balance Sheets and are amortized to interest expense 
using the effective interest method over the term of the Notes, resulting in an effective interest rate of 1.6%.  

As of December 31, 2022, the net carrying amount of the liability for the Notes is recorded as convertible senior notes, net in 
the Consolidated Balance Sheets as follows (in thousands):

As of December 31, 2022, the estimated fair value (Level 2) of the Notes was $604.8 million. The fair value of the Notes is 
estimated using a pricing model that is primarily affected by the trading price of our common stock and market interest rates. 

NOTE 8. COMMITMENTS AND CONTINGENCIES  

Leases 

We record operating lease right-of-use assets and liabilities on our Consolidated Balance Sheets for all leases with a term of 
more than 12 months. In connection with the acquisition of Omniome, we acquired $18.1 million in right-of-use assets and 
liabilities on our Consolidated Balance Sheets. The operating lease right-of-use assets and liabilities are calculated as the 
present value of remaining minimum lease payments over the remaining lease term using our estimated secured incremental 
borrowing rates at the commencement date. Lease payments included in the measurement of the lease liability comprise 
the fixed rent per the term of the Lease. All of our leases are operating leases. Lease payments comprise the base rent per 
the term of the Lease. Lease expense for these leases is recognized on a straight-line basis over the lease term, with variable 
lease payments, such as common area maintenance fees, recognized in the period those payments are incurred. 

We often have options to renew lease terms for buildings. In addition, certain lease arrangements may be terminated prior to 
their original expiration date at our discretion. We evaluate renewal and termination options at the lease commencement 
date to determine if we are reasonably certain to exercise the option on the basis of economic factors.

We use our incremental borrowing rate to determine the present value of lease payments, as the implicit rates in our leases 
are not readily determinable. The weighted-average discount rate used to measure our operating lease liabilities was 6.7%. 
The weighted-average remaining lease term for our operating leases as of December 31, 2022 was 4.7 years. 

Cash Flows 

Cash paid for amounts included in the present value of operating lease liabilities was $11.2 million and $8.2 million for the 
years ended December 31, 2022 and 2021, respectively, and were included in operating cash flow.  

Operating Lease Costs 

Operating lease costs were $10.5 million and $7.2 million for the years ended December 31, 2022 and 2021, respectively. 

Contingencies  

We may become involved in legal proceedings, claims and assessments from time to time in the ordinary course of business. 
We accrue liabilities for such matters when it is probable that future expenditures will be made and such expenditures can 
be reasonably estimated.  

We do not believe that the ultimate outcome of any such pending matters is probable or reasonably estimable, or that these 
matters  will  have  a  material  adverse  effect  on  our  business;  however,  the  results  of  litigation  and  claims  are  inherently 
unpredictable. Regardless of the outcome, litigation can have an adverse impact on us because of litigation and settlement 
costs, diversion of management resources, and other factors. 

Please see subsection titled Legal Proceedings, in Part I, Item 3 of this Annual Report on Form 10-K. 

Indemnification 

Pursuant to Delaware law and agreements entered into with each of our directors and officers, we may have obligations, 
under certain circumstances, to hold harmless and indemnify each of our directors and officers against losses suffered or 
incurred by the indemnified party in connection with their service to us, and judgements, fines, settlements and expenses 
related to claims arising against such directors and officers to the fullest extent permitted under Delaware law, our bylaws 
and our certificate of incorporation. We also enter and have entered into indemnification agreements with our directors and 
officers that may require us to indemnify them against liabilities that arise by reason of their status or service as directors or 
officers, except as prohibited by applicable law. In addition, we may have obligations to hold harmless and indemnify third 
parties involved with our fundraising efforts and their respective affiliates, directors, officers, employees, agents or other 
representatives  against  any  and  all  losses,  claims,  damages  and  liabilities  related  to  claims  arising  against  such  parties 
pursuant to the terms of agreements entered into between such third parties and us in connection with such fundraising 
efforts.  To  the  extent  that  any  such  indemnification  obligations  apply  to  the  lawsuits  described  above,  any  associated 
expenses incurred are included within the related accrued litigation expense amounts. No additional liability associated with 
such indemnification obligations has been recorded as of December 31, 2022. 

Purchase Commitments 

In the normal course of business, we enter into agreements to purchase goods or services or license intellectual property, 
certain of which are not cancelable without penalty. For those agreements with variable terms, we do not estimate the total 
obligation beyond any minimum quantities or pricing as of the reporting date. Licensing agreements under which we commit 
to  ongoing  minimum  royalty  payments,  some  of  which  are  subject  to  adjustment,  may  be  terminated  under  certain 
circumstances.

Our purchase orders and contractual obligations are approximately $145.7 million as of December 31, 2022, which consist 
of open purchase orders and contractual obligations in the ordinary course of business, including commitments with contract 
manufacturers and suppliers for which we have not received the goods or services. A majority of these purchase obligations 
are due within a year. Although open purchase orders are considered enforceable and legally binding, the terms generally 
allow us the option to cancel, reschedule and adjust our requirements based on our business needs prior to the delivery of 
goods or performance of services. 

We recognized a loss on purchase commitment of $3.7 million for the year ended December 31, 2022, which was recorded 
as part of accrued expenses on the Consolidated Balance Sheet and is included in the aforementioned purchase orders and 
contractual obligations amount. The purchase commitment loss is based on an estimate of future excess inventory related 
to a supply agreement with a third-party vendor, for which we do not expect to have related sales. 

We have a long-term supply agreement, which was amended in October 2022 (the “Supply Agreement”), for the purchase of 
certain products with a semiconductor manufacturer (“Supplier”). The Supply Agreement provides for minimum purchase 
commitments through 2026 on our part in exchange for guaranteed capacity at Supplier. We are responsible for providing 
certain materials to allow our Supplier to perform its obligations under the contract.  

We paid our Supplier a deposit of $9.0 million in November 2022 and will pay an additional deposit of $6.0 million in 2023, 
for a total of $15.0 million (the “Deposit”). The Deposit is fully refundable to us, in accordance with the Supply Agreement, if 
we meet the minimum volume purchase commitment for the applicable year. As of December 31, 2022, $9.0 million related 
to the Deposit was included in other long-term assets in the Consolidated Balance Sheets, as we believe it is probable the 
minimum volume purchase commitment level will be achieved. 

NOTE 9. INCOME TAXES 

We  are  subject  to  income  taxes  in  the  United  States  and  certain  states  in  which  we  operate,  and  we  use  estimates  in 
determining our provisions for income taxes. Significant management judgement is required in determining our provision for 
income  taxes,  deferred  tax  assets  and  liabilities,  and  valuation  allowances  recorded  against  net  deferred  tax  assets  in 
accordance with U.S. GAAP. These estimates and judgements occur in the calculation of tax credits, benefits, and deductions, 
and in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue 
and expense for tax and financial statement purposes, as well as the interest and penalties related to uncertain tax positions. 
Significant changes to these estimates may result in an increase or decrease to our tax provision in the current or subsequent 
period. 

We assess all material positions taken in any income tax return, including all significant uncertain positions, in all tax years 
that are still subject to assessment or challenge by relevant taxing authorities. Assessing an uncertain tax position begins 
with the initial determination of the position’s sustainability and is measured at the largest amount of benefit that is greater 
than 50% likely of being realized upon ultimate settlement. As of each balance sheet date, unresolved uncertain tax positions 
must be reassessed, and we will determine whether the factors underlying the sustainability assertion have changed and the 
amount of the recognized tax benefit is still appropriate. 

We account for Global Intangible Low-taxed Income as a period cost. 

During the years ended December 31, 2022, 2021, and 2020 (loss) income before taxes from U.S. operations were ($315.7) 
million, ($275.4) million, and $28.9 million, respectively, and income before taxes from foreign operations was $1.8 million, 
$0.8 million, and $0.6 million, respectively.  

Income tax provision (benefit) related to continuing operations differ from the amounts computed by applying the statutory 
income tax rate of 21% to pretax income or loss as follows:

At December 31, 2022, we maintained a full valuation allowance against all of our deferred tax assets that totaled $445.6 
million, including net operating loss carryforwards and research and development credits of $400.6 million and $71.5 million, 
respectively. 

A valuation allowance is recorded when it is more likely than not that all or some portion of the deferred income tax assets 
will  not  be  realized.  We  regularly  assess  the  need  for  a  valuation  allowance  against  our  deferred  income  tax  assets  by 
considering both positive and negative evidence related to whether it is more likely than not that our deferred income tax 
assets will be realized. In evaluating our ability to recover our deferred income tax assets within the jurisdiction from which 
they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred income tax 
liabilities, projected future taxable income, tax-planning strategies, and results of recent operations. We maintain a valuation 
allowance on the net deferred tax assets of our U.S. entities as we have concluded that it is more likely than not that we will 
not realize our deferred tax assets. Accordingly, this benefit from income taxes is reflected on our Consolidated Statements 
of Operations and Comprehensive (Loss) Income for the year ended December 31, 2022.  

For the year ended December 31, 2022, our valuation allowance increased to $445.6 million, primarily because of an increase 
in our net operating losses, credits, and capitalized research and experimental expenses that were fully offset by a valuation 
allowance. For the year ended December 31, 2021, our valuation allowance increased to $366.9 million, primarily because of 
an increase in our net operating losses, credits, and acquisition of deferred tax assets that were fully offset by a valuation 
allowance.  

As  of  December 31,  2022,  we  had  a  net  operating  loss  carryforward  for  federal  income  tax  purposes  of  approximately 
$1,573.8 million, of which $774.9 million will begin to expire in 2024 if not utilized. We had a total state net operating loss 
carryforward of approximately $1,071.8 million, which are subject to annual expirations. Utilization of some of the federal 
and state net operating loss and credit carryforwards are subject to annual limitations due to the “change of ownership” 
provisions  of  the  Internal  Revenue  Code  of  1986  and  similar  state  provisions.  The  annual  limitations  may  result  in  the 
expiration of net operating losses and credits before utilization.  

We have federal credits of approximately $47.2 million, which will begin to expire in 2024 if not utilized and state research 
credits of approximately $42.6 million, which have no expiration date. These tax credits are subject to the same limitations 
discussed above.

Our  practice  is  to  recognize  interest  and  penalties  related  to  income  tax  matters  in  income  tax  expense.  As  of  both 
December 31, 2022 and 2021, we had no accrued interest or penalties due to our net operating losses available to offset any 
tax adjustment. If total unrecognized tax benefits were realized in the future, it would not result in any tax benefit as we 
currently have a full valuation allowance. We file U.S. federal and various state income tax returns. For U.S. federal and state 
income tax purposes, the statute of limitations currently remains open for the years ending December 31, 2019 to present 
and December 31, 2018 to present, respectively. In addition, all of the net operating losses and research and development 
credit  carryforwards  that  may  be  utilized  in  future  years  may  be  subject  to  examination.  We  are  not  currently  under 
examination by income tax authorities in any jurisdiction. 

NOTE 10. STOCKHOLDERS’ EQUITY 

Preferred Stock  

Our Certificate of Incorporation, as amended and restated in October 2010 in connection with the closing of our initial public 
offering, authorizes us to issue 1,000,000,000 shares of $0.001 par value common stock and 50,000,000 shares of $0.001 
par value preferred stock. As of December 31, 2022 and 2021, there were no shares of preferred stock issued or outstanding. 

Common Stock  

Common stockholders are entitled to dividends when and if declared by our board of directors. There have been no dividends 
declared to date. The holder of each share of common stock is entitled to one vote.  

Underwritten Public Equity Offerings 

In  August  2020,  we  entered  into  an  underwriting  agreement,  relating  to  the  public  offering  of  19,430,000  shares  of  our 
common stock, $0.001 par value per share, at a price to the public of $4.47 per share. Under the terms of the underwriting 
agreement, we also granted the underwriters a 30-day option to purchase up to an additional 2,914,500 shares of our common 
stock, which was subsequently exercised in full, and the offering including the sale of shares of common stock subject to the 
underwriters’ option, closed in August 2020. In total, we sold 22.3 million shares of our common stock. We paid a commission 
equal to 6% of the gross proceeds from the sale of shares of our common stock. The total net proceeds to us from the 
offering after deducting the underwriting discount were approximately $93.9 million, excluding approximately $0.3 million of 
offering expenses.  

In  November  2020,  we  entered  into  an  underwriting  agreement,  relating  to  the  public  offering  of  6,096,112  shares  of  our 
common stock, $0.001 par value per share, at a price to the public of $14.25 per share. Under the terms of the underwriting 
agreement, we also granted the underwriters a 30-day option to purchase up to an additional 914,416 shares of our common 
stock, which was subsequently exercised in full, and the offering including the sale of shares of common stock subject to the 
underwriters’  option,  closed  in  November  2020. In  total,  we  sold  7.0  million  shares  of  our  common  stock.  We  paid  a 
commission equal to 6% of the gross proceeds from the sale of shares of our common stock. The total net proceeds to us 
from the offering after deducting the underwriting discount were approximately $93.9 million, excluding approximately $0.3 
million of offering expenses.  

In  total,  for  the  year  ended  December  31,  2020,  we  issued  29.4  million  shares  of  our  common  stock  through  our  two 
underwritten public offerings with an average offering price of $6.40. The total net proceeds to us from the two offerings, 
after deducting the underwriting commission and offering expenses, were approximately $187.2 million.  

Private Placement of Common Stock 

On July 19, 2021, in connection with the Omniome acquisition, we entered into a purchase agreement with certain qualified 
institutional buyers and institutional accredited investors, pursuant to which we agreed to sell an aggregate of 11,214,953 
shares of common stock, at a price of $26.75 per share, for aggregate gross proceeds of approximately $300 million. The 
transaction closed on September 20, 2021. We registered the private placement shares for resale following the closing of the 
merger.

Equity Plans  

The 2020 Equity Incentive Plan (the “2020 Plan”), the 2020 Inducement Equity Incentive Plan (the “Inducement Plan”), and 
the 2021 adopted Omniome Equity Incentive Plan of Pacific Biosciences of California, Inc. (the “Omniome Plan”) allow for 
the issuance of stock options, restricted units and awards, and performance-based awards. 

On August 4, 2020, stockholders approved the 2020 Plan and reserved 11,000,000 shares of our common stock for issuance 
pursuant to equity awards granted under the 2020 Plan.  

On December 2, 2020, the Board of Directors (the “Board”) adopted the Inducement Plan and reserved 2,500,000 shares of 
our  common  stock  for  issuance  pursuant  to  equity  awards  granted  under  the  Inducement  Plan.  On  April  18,  2021  and 
November  22,  2021,  the  Board  amended  the  Inducement  Plan  to  reserve  an  additional  750,000  and  360,000  shares, 
respectively.  

On September 20, 2021, in connection with the acquisition of Omniome, we adopted the Omniome Equity Incentive Plan of 
Pacific Biosciences of California, Inc. (the “Omniome Plan”). Under the Omniome Merger Agreement, each unvested option 
to purchase Omniome common stock, granted under the Omniome Plan held by employees continuing with us, was assumed 
by PacBio and converted into an option to purchase shares of our common stock. The terms and conditions of the converted 
options are substantially the same (including vesting and exercisability), except that (A) the assumed options cover shares 
of PacBio’s common stock; (B) the number of shares of our common stock subject to the assumed option is equal to the 
product of (i) the number of shares of Omniome common stock subject to the corresponding unvested option, multiplied by 
(ii) the exchange ratio (as defined below), with any resulting fractional share rounded down to the nearest whole share; and 
(C) the exercise price per share of the assumed options is equal to the quotient of (i) the exercise price per share of the 
corresponding unvested option to purchase shares of Omniome common stock, divided by (ii) the exchange ratio (as defined 
below),  with  any  resulting  fractional  cent  rounded  up  to  the  nearest  whole  cent.  The  exchange  ratio  was  equal  to 
0.259204639.  We  reserved  2,494,128  shares  of  our  common  stock  for  issuance  pursuant  to  equity  awards  under  the 
Omniome Plan.  

On May 25, 2022, stockholders approved an amendment to the 2020 Plan and we reserved an additional 18,000,000 shares 
of our common stock for issuance pursuant to equity awards granted under the 2020 Plan. 

As  of  December 31,  2022,  we  had  18.9  million  shares  remaining  and  available  for  future  issuance  under  the  2020  Plan, 
Inducement Plan, and the Omniome Plan.

The aggregate intrinsic value of outstanding options represents the total pre-tax intrinsic value (i.e. the difference between 
$8.18, our closing stock price on the last trading day of our fourth quarter of 2022 and the option exercise price multiplied by 
the number of in-the-money options) that would have been received by the option holders had all option holders exercised 
their options on December 31, 2022. The aggregate intrinsic value changes at each reporting date based on the fair market 
value of our common stock.

The aggregate intrinsic value of the outstanding options presented in the table above as of December 31, 2022, totaled $24.7 
million, and had a weighted-average remaining contractual life of 6.7 years. 

The vested and exercisable options as of December 31, 2022, totaled 9,408,063 shares, had an aggregate intrinsic value of 
$22.7 million, a weighted-average exercise price per share of $8.45, and a weighted-average remaining contractual life of 5.4 
years.  

The vested and expected to vest options as of December 31, 2022, totaled 14,436,695 shares, had an aggregate intrinsic 
value of $24.6 million, a weighted-average exercise price per share of $10.61, and a weighted-average remaining contractual 
life of 6.5 years.  

The total intrinsic value of stock options exercised during the years ended December 31, 2022, 2021, and 2020 was $5.0 
million, $146.1 million, and $63.1 million, respectively.  

The total intrinsic value of options exercised represents the difference between our closing stock price on the exercise date 
and the option exercise price, multiplied by the number of in-the-money options exercised. 

The weighted-average grant-date fair value of all options granted was $5.93 in 2022, $18.36 in 2021, and $4.14 in 2020, each 
determined by the Black-Scholes option valuation method. 

Restricted Stock Units  

Each Restricted Stock Unit (RSU) represents one equivalent share of our common stock to be issued after satisfying the 
applicable continued service-based vesting criteria over a specified period. These RSUs are time-based and vest over four 
years at a rate of 25% annually. The fair value for these RSUs is based on the closing price of our common stock on the date 
of grant. We measure compensation expense for these RSUs at fair value on the date of grant and recognize the expense 
over the  expected  vesting  period  on  a straight-line basis. The  RSUs  do  not  entitle  participants  to the  rights  of  holders  of 
common stock, such as voting rights, until the shares are issued. RSUs that are expected to vest are net of estimated future 
forfeitures.  

The  following  table  summarizes  the  RSU  activity  for  the  year  ended  December  31,  2022  (in  thousands,  except  per  share 
amounts):

The weighted-average grant-date fair value of all RSUs granted was $10.15 in 2022, $35.33 in 2021, and $5.18 in 2020. 

Employee Stock Purchase Plan  

As of December 31, 2022, a total of 25.5 million shares of our common stock have been reserved for issuance under our 
2010 Employee Stock Purchase Plan (the “ESPP”). The ESPP permits eligible employees to purchase common stock at a 
discount  through  payroll  deductions  during  defined  offering  periods.  Each  offering  period  will  generally  consist  of  four 
purchase periods, each purchase period being approximately six months. The price at which the stock is purchased is equal 
to the lower of 85% of the fair market value of the common stock at the beginning of an offering period or at the end of a 
purchase  period.  Each  offering  period  will  generally  end  and  the  shares  will  be  purchased  twice  yearly  on  March  1  and 
September 1. If the stock price at the end of the purchase period is lower than the stock price at the beginning of the offering 
period, that offering period will be terminated and a new offering period will come into place. The ESPP provides for an annual 
increase to the shares available for issuance at the beginning of each fiscal year equal to the lessor of 2% of the common 
shares then outstanding, 4,000,000 shares, or an amount determined by the ESPP’s administrator.  

Pursuant to the terms of the then-in-process Merger Agreement with Illumina, offerings under our 2010 ESPP were suspended 
after the completion of the purchase period ended March 1, 2019. After the merger with Illumina was terminated in January 
2020, we began offerings under the ESPP again starting with the offering period beginning March 1, 2020.  

For the years ended December 31, 2022, 2021, and 2020, 1,878,168 shares, 1,913,968 shares, and 834,677 shares of common 
stock were purchased under the ESPP, respectively. As of December 31, 2022, 9,932,505 shares of our common stock remain 
available for issuance under our ESPP.

inventory, net, on our consolidated balance sheets, respectively.  

The tax benefit of share-based compensation expense was immaterial for the years ended December 31, 2022, 2021, and 
2020.  

Determining Fair Value 

We estimate the fair value of share options granted using the Black-Scholes valuation method and a single option award 
approach. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is 
generally the vesting period. The fair market value of RSU awards granted is the closing price of our shares on the date of 
grant and is generally recognized as compensation expense on a straight-line basis over the respective vesting period. For 
shares purchased under our Employee Stock Purchase Plan, or ESPP, we estimate the grant-date fair value, and the resulting 
share-based compensation expense, using the Black-Scholes option-pricing model. 

Expected Term – The expected term used in the Black-Scholes valuation method represents the period that the stock options 
are expected to be outstanding and is determined based on historical experience of similar awards, giving consideration to 
the contractual terms of the stock options and vesting schedules. 

Expected Volatility – The expected volatility used in the Black-Scholes valuation method is derived from the implied volatility 
related to our share price over the expected term. 

Expected Dividend – We have never paid dividends on our shares and, accordingly, the dividend yield percentage is zero for 
all periods. 

Risk-Free Interest Rate – The risk-free interest rate used in the Black-Scholes valuation method is the implied yield currently 
available on U.S. Treasury constant maturities issued with a term equivalent to the expected terms. 

Stock Options 

We  estimated  the  fair  value  of  employee  stock  options  using  the  Black-Scholes  option  pricing  model.  The  fair  value  of 
employee stock options is being amortized on a straight-line basis over the requisite service period of the awards.  

When determining the current share prices underlying the stock options for calculating the grant-date fair value, we reference 
observable market prices of similar or identical instruments in active markets.  

The fair value of employee stock options was estimated using the following weighted-average assumptions: 

Expected term in years

Risk-free interest rate

We  are  organized  as,  and  operate  in,  one  reportable  segment:  the  development,  manufacturing,  and  marketing  of  an 
integrated  platform  for  genetic  analysis.  Our  chief  operating  decision-maker  is  our  Chief  Executive  Officer.  The  Chief 
Executive Officer reviews financial information presented on a consolidated basis for the purposes of evaluating financial 
performance and allocating resources, accompanied by information about revenue by geographic regions. Our assets are 
primarily  located  in  the  United  States  of  America  and  not  allocated  to  any  specific  region,  and  we  do  not  measure  the 
performance of geographic regions based upon asset-based metrics. Therefore, geographic information is presented only

ITEM 9A.  CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures  

Our management, with the participation of our chief executive officer, our chief financial officer, and our principal accounting 
officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a–15(e) and 15d–15(e) 
of  the  Exchange  Act)  as  of  the  end  of  the  period  covered  by  this  Annual  Report  on  Form  10–K.  Disclosure  controls  and 
procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed 
by  a  company  in  the  reports  that  it  files  or  submits  under  the  Exchange  Act  is  accumulated  and  communicated  to  our 
management,  including  its  principal  executive  and  principal  financial  officers,  as  appropriate  to  allow  timely  decisions 
regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and 
operated,  can  provide  only  reasonable  assurance  of  achieving  their  objectives,  and  management  necessarily  applies  its 
judgement in evaluating the cost-benefit relationship of possible controls and procedures. Based on this evaluation, our chief 
executive  officer,  chief  financial  officer  and  our  principal  accounting  officer  concluded  that  our  disclosure  controls  and 
procedures were effective as of the end of the period covered by this report.  

Management’s Report on Internal Control Over Financial Reporting  

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such 
term  is  defined  in  Exchange  Act  Rules  13a-15(f).  Pacific  Biosciences  of  California,  Inc’s  internal  control  over  financial 
reporting is designed to provide reasonable assurance to the Company’s management and board of directors regarding the 
preparation and fair presentation of published financial statements. Because of its inherent limitations, internal control over 
financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can 
provide only reasonable assurance with respect to financial statement preparation and presentation. Management assessed 
the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of  December  31,  2022.  In  making  this 
assessment,  management  used  the  criteria  set  forth  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (2013 framework) (the COSO criteria). Based on our assessment, we concluded that, as of December 31, 2022, 
the Company’s internal control over financial reporting was effective based on those criteria. 

The Company’s internal control over financial reporting as of December 31, 2022 has been audited by Ernst &Young LLP, the 
independent  registered  public  accounting  firm  who  also  audited  the  Company’s  financial  statements.  Ernst  &Young’s 
attestation report on the Company’s internal control over financial reporting appears on page 91 hereof. 

Changes in Internal Control Over Financial Reporting  

There were no material changes in our internal control over financial reporting identified in connection with the evaluation 
required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the year ended December 31, 2022, that 
have materially affected, or were reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and the Board of Directors of Pacific Biosciences of California, Inc. 

Opinion on Internal Control over Financial Reporting 

We have audited Pacific Biosciences of California, Inc.’s internal control over financial reporting as of December 31, 2022, 
based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Pacific Biosciences of 
California, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2022, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the 2022 consolidated financial statements of the Company and our report dated February 28, 2023, expressed 
an unqualified opinion thereon. 

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s 
Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal 
control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform 
the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in 
all material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed 
risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit 
provides a reasonable basis for our opinion.  

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and 
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection 
of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
