Overview

PART I

We  are  a  growing  cancer  genomics  company  transforming  the  development  of  next-generation  therapies  by  providing  more  comprehensive
molecular data about each patient’s cancer and immune response. We designed our NeXT Platform to adapt to the complex and evolving understanding of
cancer, providing our biopharmaceutical customers with information on all of the approximately 20,000 human genes, together with the immune system, in
contrast to many cancer panels that cover roughly only 50 to 500 genes. In parallel with the development of our platform technology, we have also pursued
business within the population sequencing market, and we have provided whole genome sequencing services under contract with the U.S. Department of
Veterans  Affairs  (the  “VA”)  Million  Veteran  Program  (the  “VA  MVP”),  which  has  enabled  us  to  innovate,  scale  our  operational  infrastructure,  and  achieve
greater  efficiencies  in  our  lab.  In  September  2020,  we  announced  receipt  of  a  new  task  order  from  the  VA  MVP  with  an  approximate  value  of  up  to  $31
million. The cumulative value of task orders received from the VA MVP since inception is approximately $175 million, approximately $132.5 million of which
we had recognized as revenue as of December 31, 2020.

In  August  2020,  we  launched  NeXT  Liquid  Biopsy,  which  is  a  liquid  biopsy  assay  that  analyzes  all  of  the  approximately  20,000  human  genes
versus the more narrowly focused liquid biopsy assays that are currently available. By combining technological innovation, operational scale, and regulatory
differentiation, our NeXT Platform is designed to help our customers obtain new insights into the mechanisms of response and resistance to therapy as well
as new potential therapeutic targets. Our platform enhances the ability of biopharmaceutical companies to unlock the potential of conducting translational
research in the clinic rather than with pre-clinical animal models or cancer cell lines. We also announced in January 2020 a diagnostic test, NeXT Dx Test,
which is based on our NeXT Platform, that we envision being used initially by both leading clinical cancer centers as well as biopharmaceutical companies.
Most  recently,  in  December  2020,  we  launched  two  new  capabilities  that  are  integrated  into  our  NeXT  Platform:  our  Systemic  HLA  Epitope  Ranking  Pan
Algorithm  (“SHERPA”)  machine  learning-based  tool  for  the  comprehensive  identification  and  characterization  of  cancer  neoantigens,  as  well  as  our
Neoantigen  Presentation  Score  (“NEOPS”)  for  predicting  cancer  immunotherapy  response.  SHERPA  enables  the  development  of  new  neoantigen-based
diagnostic biomarkers, such as our NEOPS, and novel personalized therapies.

We  have  the  capacity  to  sequence  and  analyze  approximately  200  trillion  bases  of  deoxyribonucleic  acid  (“DNA”)  per  week  in  our  facility.  We
believe our capacity for this is already larger than the sequencing capacities of most cancer genomics companies, and we continue to build automation and
other infrastructure to scale further as demand increases and in support of our NeXT Liquid Biopsy. To date, we have sequenced more than 150,000 human
samples, of which more than 100,000 were whole human genomes.

Our  headquarters  –  housing  our  Clinical  Laboratory  Improvement  Amendments  of  1988  (“CLIA”)-certified,  College  of  American  Pathologists
(“CAP”)-accredited laboratory – is located in Menlo Park, CA. We were incorporated under the laws of the state of Delaware in February 2011 under the
name  Personalis,  Inc.  Our  customers  include  biopharmaceutical  companies  (including  large  pharmaceutical  companies),  universities,  non-profits,  and
government entities such as the VA MVP.

Personalis: The Genomics Engine for Next-Generation Cancer Therapies

Biopharmaceutical  customers  use  our  comprehensive  platform  across  a  diverse  set  of  therapeutic  approaches  to  cancer.  We  generate  and
analyze  data  from  patients  who  participated  in  clinical  trials,  which  we  believe  will  enable  these  customers  to  develop  more  effective  therapies.  The
information we generate is important to our customers developing three major classes of next-generation therapeutics: immunotherapies, targeted therapies,
and personalized cancer therapies.

•

•

•

Immunotherapies: Over the past decade, a number of drugs have emerged based on the discovery that the immune system plays a key
role in addressing cancer. Checkpoint inhibitors, a specific type of immunotherapy, have generated substantial commercial success over the
past decade; however, the development of new therapies in this category has been challenged by difficulties in understanding the precise
interaction between cancer and the immune system. Since our platform provides a broad set of insights on tumor and immune biology, we
believe it enables biopharmaceutical companies to better understand how therapeutics are working in patients.

Targeted  Therapies:  A  growing  category  of  successful  cancer  treatments  consists  of  therapies  that  target  specific  genes  or  molecular
mechanisms of cancer. Many of these targeted therapies are proposed to be tested in combination with immunotherapies. These therapies
have  grown  to  represent  a  considerable  share  of  the  overall  oncology  therapeutics  market  today.  Comprehensively  understanding  each
patient’s genomic and immune profile is critical to understanding how a patient may respond to such therapies. We believe that our coverage
of all of the approximately 20,000 genes provides us a strong competitive advantage against existing cancer panels that cover roughly only
50 to 500 genes. We believe our company is positioned to become a leading provider of the complex information that we believe will continue
to inform the development of targeted cancer therapies.

Personalized Cancer Therapies: Many biopharmaceutical companies are pursuing personalized cancer therapies, which are designed and
manufactured  individually  for  each  patient  based  on  genomic  alterations  in  a  given  patient’s  tumor.  While  there  are  many  potential
approaches to developing these therapies, including neoantigen-based vaccines and T-cell therapies, all of them could benefit from the data
and analytics that our platform can generate about a patient’s tumor.

4

 
 
 
 
 
 
 
 
Many  of  our  customers  have  leveraged  our  U.S.  Food  and  Drug  Administration  (the  “FDA”)  Device  Master  File  as  a  component  of  their
investigational new drug (“IND”) filings with the FDA. If drugs that used our platform in the clinical trials to form the basis for approval are
approved,  we  may  be  able  to  derive  revenue  in  connection  with  the  sale  of  these  drugs.  We  believe  we  are  working  with  the  majority  of
companies developing neoantigen-targeted personalized cancer therapies.

We  anticipate  that  as  the  clinical  utility  of  our  platform  is  validated,  we  will  have  opportunities  in  connection  with  diagnostics  and  the
commercialization  of  cancer  therapeutics,  which  are  significantly  larger  than  our  initial  clinical-trial  focused  markets.  Over  time,  we  expect  our
biopharmaceutical customers and research collaborators to build evidence of the clinical utility of our platform as a diagnostic for advanced cancer therapies.
Separately, we are also acquiring samples and building a database which we expect will hold value for our biopharmaceutical customers and may ultimately
allow us to discover new mechanisms of cancer treatment.

Financial Highlights

Our revenues have grown rapidly as our penetration of clinical trials in advanced oncology therapeutics and our relationship with the VA MVP has
expanded,  consistent  with  our  reputation  as  a  leader  in  the  field.  We  generated  revenues  of  $37.8  million,  $65.2  million,  and  $78.6  million  for  the  years
ended December 31, 2018, 2019, and 2020, respectively. We also incurred net losses of $19.9 million, $25.1 million, and $41.3 million for the years ended
December  31,  2018,  2019,  and  2020,  respectively.  We  have  one  reportable  segment  from  the  sale  of  sequencing  and  data  analysis  services  and
substantially all of our revenues to date have been derived from sales in the United States.

As  of  December  31,  2020,  we  had  $203.3  million  of  cash  and  cash  equivalents  and  short-term  investments,  an  increase  of  $75.0  million  from
December  31,  2019.  Our  revenues  are  primarily  generated  through  sales  of  our  services  to  the  VA  MVP  and  biopharmaceutical  companies.  Unlike
diagnostic or therapeutic companies, we have not sought reimbursement through traditional healthcare payors. We raised $144.0 million and $117.5 million
in our June 2019 initial public offering and August 2020 follow-on offering, respectively, net of underwriting discounts and commissions.

Subsequent to the fiscal period ended December 31, 2020 covered by this Annual Report on Form 10-K, on January 29, 2021, we completed a
follow-on offering in which we issued and sold 3,950,000 shares of common stock at a public offering price of $38.00 per share. We received net proceeds of
$141.1 million after deducting underwriting discounts and commissions. The underwriters exercised their option to purchase an additional 592,500 shares
shortly thereafter, resulting in additional net proceeds to us of $21.2 million after deducting underwriting discounts and commissions. In total, we raised net
proceeds of $162.3 million after deducting underwriting discounts and commissions.

Market Opportunities

We estimate the market opportunity for our current and planned products to be approximately $38 billion as follows:

•

•

Therapy  Selection  and  Monitoring:  According  to  the  American  Cancer  Society’s  Cancer  Facts  &  Figures  2020,  more  than  16.9  million
cancer survivors were alive on January 1, 2019 in the United States. Based on data from Cancer Treatment and Survivorship Statistics, 2019
and Cancer Statistics, 2019, we estimate that approximately 2.2 million of these cancer survivors were diagnosed within the last two years.
Over  time,  the  likelihood  that  the  original  cancer  will  reoccur  can  decline  below  the  baseline  likelihood  of  a  new,  genetically  independent
cancer emerging. Therefore, we limit our analysis to patients within the period of two years from their initial cancer diagnosis.

Of  these  2.2  million  patients,  about  200,000  enroll  in  pharmaceutical  clinical  trials  according  to  data  from  the  U.S.  National  Library  of
Medicine, ClincalTrials.gov, January 2019, with the assumption that the remaining cancer patients undergo normal clinical care. As part of
that standard care, these patients go through therapy selection and eventual monitoring. For therapy selection, we estimate that each of the
approximately  2.0  million  cancer  patients  undergoing  normal  clinical  care  will  have  a  tissue  biopsy  sequenced  and  tested  at  a  cost  of
approximately  $3,000,  which  is  the  approved  CMS  reimbursement  rate,  which  results  in  an  estimated  potential  market  opportunity  of  $6
billion per year.

Cancer  mutations  identified  in  this  initial  tissue-biopsy  based  test  can  then  be  used  for  subsequent  monitoring  using  cell  free  DNA.  For
monitoring, we estimate that each patient has a liquid biopsy sequenced and tested four times per year at an estimated cost of $2,840 per
test, based on publicly-available data on comparable tests. Our NeXT Dx Test addresses this market for tissue biopsy testing while clinical
versions  of  our  products  in  development  may  address  this  liquid-biopsy  based  monitoring  opportunity.  Our  estimates  lead  us  to  project
approximately a $22.72 billion potential market opportunity per year for monitoring.

Clinical  Trial  Patients:  For  each  of  the  200,000  pharmaceutical  clinical  trial  patients,  we  estimate  that  an  initial  tissue  sample  will  be
sequenced at least once at a cost of $3,000, which is the approved CMS reimbursement rate, and the liquid biopsy sample testing at least
eight different time points per year for monitoring, at an estimated cost of $4,000 per sequencing test, based on the frequency of monitoring
in a recent immuno-oncology drug trial and our historical standard pricing for tissue samples and anticipated pricing for liquid biopsy samples.
Based on this, we estimate the potential market opportunity to be approximately $7 billion per year for tissue- and liquid-based sequencing of
these clinical trial patients.

5

 
 
 
•

Population  Sequencing:  According  to  publicly-available  industry  information  and  presentations,  we  estimate  the  potential  market  for
population sequencing services is over $2 billion per year. Our whole genome sequencing products address this potential market opportunity.

Our Products and Services

Broadly speaking, we provide proprietary genomic information to customers. Our genomic sequencing and analytics products are focused on the

following customer applications: biopharmaceutical company research, clinical and companion diagnostics, and population sequencing.

NeXT Platform

Our  NeXT  Platform  is  a  high-accuracy,  clinical-grade,  next-generation  sequencing  and  analysis  platform.  We  have  created  an  ecosystem  of
products and capabilities built on the NeXT Platform that synergize to drive value for our customers: ImmunoID Next (comprehensive tumor profiling from
tissue), NeXT Liquid Biopsy (comprehensive tumor profiling from plasma), NeXT Dx Test (comprehensive genomic cancer profiling test enabling advanced
composite  biomarkers  for  cancer  treatment),  NeXT  SHERPA  and  NeXT  NEOPS  (neoantigen  prediction  capabilities).  We  are  currently  investing  in  the
development of additional future product offerings, including NeXT Personal (liquid biopsy offering for personalized tumor tracking for patients), NeXT CDx
(diagnostic test), and NeXT Database (comprehensive tumor immune-genomics database).

Our NeXT Platform is designed to provide comprehensive analysis of both a tumor and its immune microenvironment, from a single limited tissue
or plasma sample. Our platform covers the DNA sequence of all of the approximately 20,000 human genes. We also report on the entire transcriptome of a
tumor, which encompasses ribonucleic acid (“RNA”) expression across the approximately 20,000 human genes, allowing us to more accurately determine
which of the many genomic mutations might actually be driving tumor progression. Furthermore, our platform analyzes elements of the immune cells that
have infiltrated a tumor both from the adaptive immune system and the innate immune system.

Given the practical challenges in obtaining high-quality tumor samples via biopsy, we have developed our platform to work with a limited tumor
tissue  sample.  Biopharmaceutical  companies  face  significant  challenges  in  attempting  to  divide  samples  to  ship  to  multiple  service  providers  to  perform
different  tests.  If  a  biopharmaceutical  company  is  successful  in  acquiring  results  from  multiple  service  providers,  it  is  challenging  to  compare  the  results
across multiple data platforms from multiple service providers. Our sequencing approach, validated with orthogonal technologies, allows us to run multiple
analyses on a single sample. Our platform is composed of multiple proprietary technologies, many of which we have developed from the ground up. The
breadth of the assays that we have integrated into our platform, our proprietary sample preparation process, and the comprehensiveness of our platform
allow us to maximize the utility of often limited tumor tissue samples that our customers have from their clinical trials.

An overview of key features and differentiators of our NeXT Platform follows.

Comprehensive tumor and immune genomics from a single limited sample:

•

•
•
•
•
•
•

Sequencing and analyzing all of the approximately 20,000 human genes generates more comprehensive molecular information than current
tumor tissue and liquid biopsy panels focused on roughly 50 to 500 genes
Covers a much broader set of biomarkers for new immunotherapies and traditional targeted therapies
Analysis of both tumor DNA and RNA expression
Analysis of both tumor and normal tissue
Analysis of non-human species such as oncoviruses
NeXT liquid biopsy targets approximately 20,000 genes and enables testing at multiple time points
Proprietary technology enables superior sequencing quality and advanced analytics

Makes single, comprehensive tumor molecular profiling practical for cancer patients:

•
•
•
•

Tumor and immune molecular profiling from one limited tumor sample
Engineered to be cost-effective and scalable, with rapid turnaround times, making it suitable for large-scale profiling of cancer patients
Overcomes the need for fragmented tumor testing
One platform for both research and clinical use

Platform anticipates future cancer biomarkers that will come with evolving science:

•
•

NeXT overcomes the limitations of small panels that become out of date when new genetic biomarkers or therapeutic targets are identified
Comprehensive coverage of all genes, DNA and RNA, tumor and normal tissue, and immune biology enables our platform to accommodate
new genetic biomarkers and signatures as they are published

6

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Generates comprehensive, harmonized data across patients to enable large-scale database creation and insight:

•

•

•
•

Comprehensive profiling for large cohorts of patients leads to more useful databases for biopharmaceutical customers using our platform and
our internal database
Opportunity for integration with other sources of real-world data such as electronic health records to generate real-world evidence that may
be used by biopharmaceutical customers to inform and accelerate therapeutic development
Data harmonization, analytics, and machine learning maximize therapeutic insight
Comprehensive nature of the platform provides long-lasting data relevance, yielding new insights over time as new biomarkers are identified

Our NeXT Platform technology can analyze cell-free DNA (“cfDNA”) obtained from blood plasma, also known as a liquid biopsy. As with a tissue
biopsy, we analyze all of the approximately 20,000 human genes in each plasma sample, in contrast to currently marketed liquid biopsy panels. This cfDNA
may  be  obtained  by  a  blood  draw  concurrently  with  a  tissue  sample.  Together,  the  two  samples  can  be  used  to  provide  a  more  comprehensive  initial
characterization of the tumor. Additionally, we expect to monitor changes in tumor genetics that arise in response to therapy through serial measurements
using cfDNA samples collected across multiple time points. In 2020, we launched our first liquid biopsy assay designed to analyze all human genes so as to
detect  potential  neoantigens  and  tumor  escape  mechanisms  that  arise  under  therapeutic  pressure.  Although  we  believe  our  cfDNA  test  will  offer  new
insights,  we  believe  it  will  be  most  useful  for  our  biopharmaceutical  customers  alongside  our  primary  tumor  biopsy  product,  given  that  a  tumor  biopsy  is
required  to  analyze  gene  expression  and  elucidate  tumor-infiltrating  lymphocytes  which  are  critical  to  understanding  cancer’s  interaction  with  the  immune
system.

NeXT Liquid Biopsy was launched in August 2020 and we have received several initial customer orders in 2020 with initial deliveries expected in

2021. We are currently investing in the development of NeXT Personal, a liquid biopsy offering for personalized tumor tracking for patients.

An overview of key liquid biopsy capabilities follows.

Liquid  biopsy  approaches  look  at  cfDNA  in  plasma  samples  derived  from  the  blood.  cfDNA  is  DNA  that  is  released  into  circulation  by  cells,

including tumor cells, as a result of cell death. This cfDNA can be obtained by a blood draw and can be used to monitor changes in tumor genetics.

We believe tumor biopsy and liquid biopsy approaches to tumor molecular profiling will provide complementary information for each patient. Tumor
biopsies provide tumor immune microenvironment and tumor gene expression information that current liquid biopsy panels do not provide. Liquid biopsies
can be useful for providing additional DNA mutation information, especially for monitoring therapy response across different time points when tumor biopsies
are  not  feasible.  Unlike  typical  liquid  biopsy  panel  approaches  focused  on  roughly  only  50  to  500  driver  genes,  our  NeXT  Liquid  Biopsy  is  designed  to
sequence all of the approximately 20,000 genes in the human genome. Our broader liquid biopsy approach will help biopharmaceutical customers identify
biological changes across multiple time points for each patient in their trials that they would otherwise miss with the current, narrowly focused liquid biopsy
panels. We also believe broader coverage will enable better neoantigen prediction, broader biomarker coverage, and higher potential to identify new drug
targets.

We believe that combining tumor biopsies with cfDNA can provide a more complete picture of the spectrum of mutations found in a cancer patient.
As an example of this, we compared the mutations found in eight late-stage colorectal tumor biopsy samples with those found in the plasma taken at the
same  time.  We  found  a  range  of  overlap  between  tumor  biopsy-identified  sequence  variations  and  the  sequences  generated  using  cfDNA.  These
observations show that, while there was significant overlap between the tumor and liquid biopsy results, there were also mutations unique to tumor biopsy
and  vice  versa  (see  examples  of  this  in  Figure  2).  This  observation  underscores  the  concept  that  tissue  and  liquid  biopsies  may  be  complementary,  and
when combined, may provide a more complete picture of the patient’s disease.

Figure 2. Overlap of sequence variations detected in matched tumor and blood plasma.

Numbers indicate variants detected in the tumor only, plasma only, or in both.

We  anticipate  that  our  liquid  biopsy  approach  will  have  many  applications,  including  monitoring  of  tumor  response  to  therapy  over  many  time
points, detecting new genetic variants from evolution of the tumor under therapeutic pressure, detecting acquired mechanisms of resistance, and identifying
neoantigens.

Our NeXT Dx Test is a comprehensive genomic cancer profiling test enabling advanced composite biomarkers for cancer treatment and provides
a path from translational research to CDx on our NeXT Platform. The NeXT Dx Test helps oncologists identify potential therapies and clinical trial options for
cancer  patients.  NeXT  Dx  Test  is  one  of  the  first  cancer  diagnostic  platforms  to  profile  approximately  20,000  genes  in  both  the  tumor  exome  and
transcriptome,  providing  a  comprehensive  genomic  testing  solution  that  goes  beyond  many  existing  cancer  diagnostic  panels  that  focus  on  only  a  few
hundred genes. The NeXT Dx Test includes advanced analytics to provide a diagnostic report on genetic alterations in medically-important cancer genes, as
well  as  emerging  immunotherapy  composite  biomarkers  of  medical  importance.  Additionally,  immunotherapy-related  biomarkers  such  as  microsatellite
instability (“MSI”) status and tumor mutational burden (“TMB”) are included in the clinical report.

The NeXT Dx Test is a laboratory-developed test performed at our CAP-accredited and CLIA’88-certified laboratory that is optimized for formalin-
fixed, paraffin-embedded tumor samples. The test utilizes ImmunoID NeXT, our clinical-grade, next-generation sequencing and analysis platform, to report
base substitutions, insertions/deletions, gene fusions, and copy number alterations in cancer driver genes of clinical significance. Additionally, MSI status is
reported based on five canonical loci (BAT25, BAT26, NR-21, NR-24, and NR-27), and TMB status is reported by leveraging the exome-wide analysis of
non-synonymous somatic mutations. Based on the tumor’s molecular profile, the report delivers relevant therapy recommendations and appropriate clinical
trial matches. Each case is reviewed by a team of board-certified molecular geneticists and genetic counselors. Test results are electronically delivered to the
ordering clinician.

In  December  2020,  we  announced  the  launch  of  our  Systematic  HLA  Epitope  Ranking  Pan  Algorithm  (“SHERPA”),  our  proprietary,  machine
learning-based tool for the comprehensive identification and characterization of cancer neoantigens. Integrated into our NeXT Platform, SHERPA enables
the development of new neoantigen-based diagnostic biomarkers and novel personalized therapies. Trained on a proprietary immunopeptidomics dataset
derived  from  engineered  cell  lines,  SHERPA  improves  neoantigen  presentation  prediction  compared  to  other  in silico  methods.  With  this  advancement,
SHERPA  can  enable  more  predictive  biomarkers  for  cancer  therapy  as  well  as  facilitate  the  development  of  neoantigen-targeting,  personalized  cancer
therapies.

While most conventional in silico  methods  generally  only  assess  the  potential  MHC-binding  affinity  and  stability  of  identified  peptides,  SHERPA
goes a step further by incorporating features relating to the antigen processing machinery and RNA abundance to generate a presentation rank for each
detected peptide. We believe this will aid in determining the relative likelihood of a given neoantigen being presented and undergoing immunosurveillance. A
large drug development customer of ours has leveraged SHERPA to characterize immune response to precision genetic therapeutics in patients with rare
diseases, demonstrating the applicability of this machine learning tool in disease areas beyond cancer.

8

 
 
Our proprietary Neoantigen Presentation Score (“NEOPS”), also launched in December 2020, is one example of a SHERPA-derived composite
biomarker  that  has  shown  promise  in  predicting  immunotherapy  response  in cancer patients.  NEOPS  combines  analysis  from  our  state-of-the-art  tumor
neoantigen  prediction  tool,  SHERPA,  with  mechanisms  of  immune  evasion  to  better  predict  response  to  cancer  therapy.  NEOPS  combines  the  tumor
genomic  and  immune-related  analytics  of  our  NeXT  Platform  to  create  a  composite  biomarker  that  can  be  more  effective  in  predicting  immunotherapy
response than other, simpler biomarkers.

NeXT makes comprehensive tumor molecular profiling practical for cancer patients at scale

To deliver a comprehensive immune-genomic assessment of a tumor, we invested substantial resources to engineer NeXT to provide data and
analysis  that  would  otherwise  be  unavailable  or  require  many  individual  technologies,  which  collectively  present  significant  costs  and  logistical
impracticalities. With NeXT, we built a proprietary platform that is comprehensive, cost-effective, and scalable and enables a short turnaround time, making it
practical to profile cancer patients at scale. This has required innovation on a number of fronts.

Revenues in connection with our NeXT Platform were minimal prior to our current fiscal year ended December 31, 2020. In the current year ended
December  31,  2020,  revenues  from  our  NeXT  Platform  accounted  for  approximately  one-third  of  total  revenues,  excluding  revenues  from  the  VA  MVP
(discussed further below).

ACE Platform

The ACE Platform is the predecessor to our NeXT Platform. To address the limitations of typical NGS-based assay, we developed our patented
Accuracy  and  Content  Enhanced  (“ACE”)  technology  for  next-generation  sequencing.  ACE  improves  nucleic  acid  preparation  processes  and  combines  it
with patented assay and sequencing methods to achieve superior, high-fidelity, clinical-grade sequencing quality that ensures high sensitivity for mutations
that  can  inform  clinical  and  therapeutic  applications  such  as  neoantigen  prediction,  biomarker  identification,  and  novel  drug  target  selection.  Our  ACE
Platform powers multiple products and services to our customers including: ACE Extended Cancer Panel for DNA, ACE Extended Cancer Panel for RNA,
ACE Cancer Research Exome, and ACE Cancer Research Transcriptome.

Our ACE technology provides coverage of difficult-to-sequence gene regions across all of the approximately 20,000 human genes, filling in key
gaps left by other NGS approaches. ACE technology provides superior and uniform coverage of difficult genomic regions, such as high GC content areas,
and fills gaps and inconsistencies in sequencing to achieve an optimal output. ACE is able to deliver more comprehensive coverage not by simply generating
more  data,  but  by  generating  higher  quality  data.  We  and  others  have  shown  in  two  publications  that  our  ACE  technology  achieves  superior  gene
sequencing coverage and finishing.

The substantial majority of our revenues since inception, excluding revenues from the VA MVP (discussed below) and our growing revenues from

our NeXT Platform described above, were derived from ACE Extended Cancer Panel and Cancer Research services.

Whole Genome Sequencing

Since  2012,  we  have  been  contracted  to  provide  DNA  sequencing  and  data  analysis  services  to  the  VA  MVP.  The  VA  MVP  began  collecting
samples  in  2011  and  is  a  landmark  research  effort  aimed  at  better  understanding  how  genetic  variations  affect  health.  Up  to  two  million  veterans  are
expected to enroll in the VA MVP study. With more than 825,000 enrollees to date, the VA MVP exceeds the enrollment numbers of any single VA study or
research  program  in  the  past,  and  is  in  fact  one  of  the  largest  population  sequencing  efforts  in  history.  In  September  2017,  we  entered  into  a  one-year
contract with three one-year renewal option periods with the VA for the VA MVP, and received orders under this contract in September 2017, 2018, 2019,
and 2020. To date, we have been contracted to deliver approximately 147,000 genome sequence data sets to the VA MVP, and we expect revenue from the
contracts  awarded  to  date  to  continue  into  2021.  This  relationship  with  the  VA  MVP  has  enabled  us  to  scale  our  operational  infrastructure  and  achieve
greater efficiencies in our lab. It has also supported our development of industry-leading, large-scale cancer genomic testing. The substantial experience that
we have and expect to continue to develop in whole genome sequencing also optimally positions us for what we anticipate to be the longer-term strategic
direction of the cancer genomics industry, which may include whole genome sequencing of tumors.

The VA MVP program has accounted for a substantial amount of our revenues in recent years, 71% of our total revenues in 2020, 67% in 2019,

and 49% in 2018.

Personalis is Valuable to Biopharmaceutical Companies

We believe that our platform is valuable to our customers because:

•

•

•

•

•

Our  tumor  and  immune  molecular  profiling  capabilities  provide  an  unprecedented  breadth  of  data  from  a  single  limited  tumor
sample. We provide information on all of the approximately 20,000 human genes, as well as gene expression, the immune system, and other
elements of cancer biology, in contrast to other currently marketed panels that cover a limited range of roughly 50 to 500 genes and do not
focus  on  immune  cells.  The  commercial  success  of  immunotherapy  drugs  has  demonstrated  the  need  to  better  understand  the  immune
system.  Unfortunately,  development  of  new  therapies  in  this  category  has  been  challenged  by  difficulties  understanding  the  precise
interaction  between  cancer  and  the  immune  system.  Since  our  platform  provides  comprehensive  insights  on  tumor  and  immune  biology,
including  in  both  innate  and  adaptive  immune  cells,  we  believe  it  will  enable  drug  companies  to  better  understand  the  biological  effect  of
therapeutics in patients.

Our platform enhances the opportunity to conduct translational research by analyzing tumor tissues from patients in clinical trials,
rather  than  animal  models  or  in  vitro  cancer  cell  lines,  which  have  historically  limited  cancer  research.  While  conventional  pre-
clinical  model  systems,  such  as  animal  models  and  cancer  cell  lines,  have  been  instrumental  in  early-stage  cancer  research  and  drug
development, translation of results to the clinic has been limited and remains a significant barrier to progress, in part because these models
do not sufficiently reflect the complexity of human cancer and the human immune system. Over recent years, tools used to study tissue from
patients  have  improved  and  the  utilization  of  tissue  from  trials  has  increased.  We  believe  our  platform  represents  the  next  step  in  this
transition by further enabling biopharmaceutical companies to address the historical limitations of analyzing patient tissue comprehensively.

The  information  we  provide  to  personalized  cancer  therapy  companies  is  used  to  design  therapeutics.  Many  biopharmaceutical
companies  are  pursuing  personalized  cancer  therapies,  which  are  designed  and  manufactured,  individually,  for  each  patient  based  on
genomic  alterations  in  a  given  patient’s  tumor.  While  there  are  many  potential  approaches  towards  developing  these  therapies  including
neoantigen  therapeutics,  peptide-based  vaccines,  RNA  and  DNA  vaccines,  virally  or  bacterially  encoded  vaccines,  and  adoptive  cell
therapies, we believe all of them can benefit from the data and analytics that our platform can generate about a patient’s tumor. We anticipate
that drugs approved based on these therapeutic strategies may specify the use of our platform, enabling us to derive revenue in connection
with the sale of commercial drugs, including the data generation and information processing required to treat each patient. We believe we are
working with the majority of companies developing neoantigen-targeted personalized cancer therapies.

Our  enterprise-grade  operational  infrastructure  is  scalable,  enables  rapid  turnaround  times,  and  is  tailored  to  meet  the  unique
workflow needs of our customers. We have invested significant resources to develop an operational infrastructure that allows us to easily
customize our services for each of our customers and scale rapidly to meet their potential research and commercial demands. Moreover, we
believe our infrastructure provides customers with visibility and control over processes, ensures consistency across all components used for
the duration of each clinical trial, is fully traceable for compliance purposes, and allows us to scale while maintaining rapid turnaround times.

We offer a complementary liquid biopsy test, which also offers broad 20,000-gene coverage versus more narrowly focused liquid
biopsy tests that are currently available. As with a tissue biopsy, we analyze all of the approximately 20,000 human genes. We are not
aware of any other company developing a cfDNA platform that analyzes all of the approximately 20,000 human genes. This cfDNA may be
obtained by a blood draw concurrently with a tissue sample. Together, the two samples can be used to provide a more comprehensive initial
characterization of the tumor. Additionally, we expect to monitor changes in tumor genetics that arise in response to therapy through serial
measurements  using  cfDNA  samples  collected  across  multiple  time  points.  Our  liquid  biopsy  assay  is  designed  to  monitor  known
neoantigens and detect novel neoantigens and tumor escape mechanisms that arise under therapeutic pressure.

Our Strategy

Our mission is to transform the development of next-generation cancer therapies by providing more comprehensive molecular data about each

patient’s tumor. To achieve this mission, our strategy is to:

•

•

•

•

•

Drive continued adoption of our NeXT Platform and population sequencing with both new and existing customers.

Continue to drive the adoption and expansion of our liquid biopsy offerings.

Continue to invest in our infrastructure and ramp up efforts to obtain clinical and regulatory approvals for our NeXT Platform.

Continue to enhance and display clinical utility of the NeXT Platform through collaborations.

Expand our facility capacity and operational footprint to support our future growth.

Expand Personalis’ footprint in China through our newly formed wholly owned subsidiary, Shanghai Personalis Biotechnology Co.,
Ltd., and develop relationships with the local scientific and regulatory community.

Our Proprietary Software and Robust Operational Infrastructure

We  have  invested  significant  resources  to  develop  an  operational  infrastructure  that  allows  us  to  easily  customize  our  services  for  each  of  our
customers  and  scale  rapidly  to  meet  their  potential  research  and  commercial  demands.  Our  NeXT  Platform  is  complemented  by  our  enterprise-grade
software and bespoke information management systems that we tailor to meet our customers’ unique needs and integrate with their workflows. Moreover,
our infrastructure provides customers with visibility and control over processes, ensures consistency across all components used for the duration of each
clinical trial, is traceable for compliance purposes, and allows us to scale while maintaining rapid turnaround times.

We  designed  our  proprietary  informatics  system,  the  Symphony  Enterprise  Informatics  System  (“Symphony”),  as  a  flexible  and  scalable
enterprise-grade system used to manage the unique complexities and challenges of our genomics laboratory. Symphony integrates laboratory information
management  systems  (“LIMS”)  and  bioinformatics  systems  to  connect  laboratory  operations  with  downstream  data  analysis.  Symphony  orchestrates  all
operational  activities  from  our  laboratory  starting  with  sample  receipt  to  the  reporting  of  results  of  the  genomic  profiling  and  data  delivery.  We  also  use
machine  learning  and  artificial  intelligence  approaches  to  generate  substantial  performance  advantages  for  our  algorithms,  such  as  neoantigen  binding
prediction.

We have the capacity to sequence and analyze approximately 200 trillion bases of DNA per week in our facility. We believe this capacity is already
larger than the sequencing capacities of most cancer genomics companies, and we continue to build automation and other infrastructure to scale further as
demand increases and in support of our NeXT Liquid Biopsy. To date, we have sequenced more than 150,000 human samples, of which more than 100,000
were whole human genomes.

We  rely  on  a  limited  number  of  suppliers  for  sequencers  and  other  equipment  and  raw  materials  that  we  use  in  our  laboratory  operations.  For
example, we rely on Illumina, Inc. (“Illumina”) as the sole supplier of sequencers and various associated reagents, and as the sole provider of maintenance
and  repair  services  for  these  sequencers.  We  have  in  place  certain  agreements  and  purchase  arrangements  with  Illumina  to  satisfy  the  needs  of  our
laboratory operations.

We believe our platform is well positioned to scale rapidly and substantially as the field of personalized cancer therapies matures. We believe that
our  platform  could  be  essential  to  the  composition  and  manufacture  of  any  personalized  cancer  therapy  developed  using  our  platform.  Furthermore,  we
expect that patients would be tested at multiple time points during the course of treatment: first to design a therapy according to an initial genomic profile
generated from a tissue and/or liquid biopsy, and then as follow-up testing via liquid biopsy to detect any changes that would require therapy modifications
after initial therapeutic interventions. If a therapy that uses our NeXT Platform achieves regulatory approval, we believe that our commercial opportunity may
increase substantially.

We leverage our proprietary software, laboratory automation and protocols, and other operational and technological know-how to power our NeXT

Platform.

Our Industry

Over the past decade, the biopharmaceutical community has achieved major advances in the treatment of cancer, including approval of therapies
capable of targeting specific genetic drivers of cancer and novel immunotherapies that empower the immune system to attack cancer cells. Despite these
advances, the substantial majority of currently available cancer therapies have significant limitations, including efficacy only in certain subsets of patients,
limited  long-term  survival  rates,  and  significant  toxicities.  Moreover,  the  current  research  and  development  paradigm  in  oncology  is  beset  by  significant
inefficiencies  and  substantial  costs,  with  the  average  cost  per  patient  in  clinical  trials  reaching  approximately  $60,000  (Battelle  Technology  Partnership
Practice, Biopharmaceutical Industry-Sponsored Clinical Trials: Impact on State Economies, March 2015). While tumor molecular profiling technologies have
enhanced  research  and  development  efforts,  most  current  tumor  biopsy  and  liquid  biopsy  tests  analyze  a  relatively  narrow  set  of  roughly  only  50  to  500
tumor genes, missing key genes and immune mechanisms underlying cancer therapy. With the lack of a comprehensive profiling solution, biopharmaceutical
companies  often  attempt  to  use  a  disparate  array  of  tests  to  compensate,  resulting  in  a  fragmented  view  of  the  tumor  biology,  insufficient  tumor  sample,
logistical complexities, and increased costs. The resulting data heterogeneity makes it difficult to mine for new biological insights across cohorts of patients in
clinical trials. These piecemeal approaches to tumor molecular profiling often result in solutions that are difficult to use at scale, especially in a clinical or
therapeutic setting where simplicity, cost, turnaround time, and validation are important.

Our  platforms  help  biopharmaceutical  companies  seeking  to  develop  more  efficacious  therapies  by  comprehensively  interrogating  a  patient’s
tumor  and  immune  cells  in  detail,  both  to  discover  tumor  vulnerabilities  and  elucidate  potential  therapeutic  alternatives.  To  meet  the  demands  of  our
customers, we built our NeXT Platform to be cost-effective and scalable with rapid turnaround times for tissue sample data and analytics. The NeXT Platform
represents the next step of our ACE Platform, allowing customers to move up the value chain by gaining more information from a single sample. We believe
that our platforms have the potential to enable a research, development, and treatment paradigm that is dynamic and adaptive to the evolving genomic and
immune  system  landscape  of  patients’  tumors  over  time.  We  believe  our  technology  will  drive  this  evolving  paradigm,  which  will  ultimately  enable  our
customers  to  develop  safer  and  more  efficacious  therapeutics  (see  Figure  3).  As  the  clinical  utility  of  our  platforms  increases,  we  expect  to  grow  our
diagnostic capabilities, including the ability to guide therapy based on a patient’s changing tumor and immune system, and supporting the commercialization
of therapeutics developed by our biopharmaceutical customers.

Figure 3. Personalis NeXT Platform addresses the increasingly complex understanding of cancer.

Despite the large sums invested in research and despite new treatments, cancer remains a major challenge for modern medicine and a source of
high unmet medical need. According to the American Cancer Society’s Cancer Facts & Figures 2020,  as  of  January  1,  2019,  there  were  more  than  16.9
million people in the United States who were suffering from cancer or who had previously suffered from cancer. Cancer prevalence is increasing globally as
well. The World Health Organization (the “WHO”) predicted in its September 2018 estimates on the global prevalence of cancer that there would be 18.1
million new cancer cases and nearly 10 million cancer deaths globally in 2018. According to the WHO, the total economic impact of healthcare expenditure
and loss of productivity resulting from cancer worldwide was approximately $1.2 trillion in 2010.

Improving Cancer Treatment is Increasingly About Leveraging Molecular Data

Despite the rapid evolution of cancer therapies, the current research and development paradigm in oncology is beset by significant inefficiencies
and  costs.  Cancer  therapeutics  have  one  of  the  lowest  clinical  trial  success  rates  of  all  major  diseases.  According  to  a  study  of  7,455  drug  development
programs  during  2006  to  2015,  the  overall  likelihood  of  FDA  approval  from  Phase  I  clinical  trial  for  oncology  developmental  candidates  was  5.1%  (BIO
Industry  Analysis,  Clinical  Development  Success  Rates  2006-2015,  June  2016).  The  majority  of  currently  available  cancer  therapeutics  have  serious
limitations, including efficacy only in certain subsets of patients, limited long-term survival rates, and significant toxicities. The mechanisms underlying the
success or failure of clinical trials are often poorly understood. To develop more efficacious cancer treatments, the biopharmaceutical community is faced
with multiple key questions for a given therapeutic approach:

•
•
•
•
•
•

Why do some patients respond to treatment and others do not?
What are the underlying mechanisms of treatment resistance?
Are there additional therapeutic targets or alternative pathways that can improve outcomes?
What therapeutic combinations can improve outcomes?
Are there ways to increase patient response through personalized therapeutics?
Are there ways to reduce toxicity?

There is a growing recognition that there is a tremendous amount of untapped molecular data that can be derived from analyzing tumors from
large  numbers  of  cancer  patients,  whether  in  cancer  clinical  trials  or  post-commercialization,  that  can  help  answer  some  of  these  seminal  questions  and
accelerate therapeutic development. The threefold increase in probability of FDA approval from Phase I clinical trial for therapies with biomarkers across all
diseases and therapeutic types provides an indication of the benefits of leveraging molecular data.

Current Tumor Molecular Profiling Solutions Have Not Kept Pace with New Cancer Therapies

Biopharmaceutical companies are increasingly turning to tumor molecular profiling across large cohorts of patients to generate the data needed to
answer these questions. Unfortunately, current tumor molecular profiling methods have not kept pace with new therapy development and overlook crucial
elements of our evolving understanding of cancer biology.

12

 
 
 
 
 
 
 
Current Tumor Molecular Profiling Falls Short for New Cancer Immunotherapies

Most current tumor molecular profiling panels were designed with a focus on targeted therapies, which, along with chemotherapy, have been used
for cancer treatment for the past several decades. Targeted therapies treat cancers based on the specific genomic alterations driving their growth. Some
targeted therapies have been developed to target specific molecules that are overexpressed or mutated in cancer cells. Because targeted therapies focus on
cancer  driver  genes,  the  vast  majority  of  tumor  molecular  profiling  panels  today,  whether  tissue  or  liquid  biopsy  based,  typically  sequence  the  DNA  of
between 50 to 500 genes, just a small fraction of the approximately 20,000 human genes.

Recently, however, transformational new approaches to cancer therapy that have been developed to harness the patient’s own immune system
have changed the treatment paradigm and our understanding of cancer biology. These new immunotherapies have dramatically improved the treatment of
certain tumors that have previously been difficult to treat. Among these new immunotherapies, checkpoint inhibitors of the CTLA-4 and PD-1/PD-L1 genes
are particularly effective. These therapies help “take the brakes off” the immune system and elicit a stronger immune response against the tumor. Patients
can also be treated by adoptive cell therapy, in which the patient’s immune system is supplemented with cytotoxic cells that have been programmed to attack
cells expressing specific antigens on their tumors. There are also new opportunities for personalized cancer therapies where a new therapeutic vaccine or
cell  therapy  is  developed  for  each  patient.  Despite  early  success,  the  majority  of  patients  today  still  do  not  respond  to  immunotherapy,  underscoring  the
importance of gathering data that can help biopharmaceutical companies understand factors governing response and resistance to therapy.

With  these  new  immunotherapies  and  our  rapidly  evolving  understanding  of  cancer  biology,  we  believe  the  data  needed  to  inform  therapeutic
development goes far beyond the typical 50 to 500 genes on current tumor molecular profiling panels. The paradigm has shifted from the need to understand
mechanisms behind a single gene target to a dynamic, systems biology view involving complex interactions between thousands of genes in the tumor and
the immune system in the pathogenesis of cancer and cancer drug response.

Information  about  all  of  the  approximately  20,000  human  genes  allows  deeper  insight  into  the  biology  of  cancer,  identifying  novel  or  patient-
specific therapeutic targets, including neoantigens, and predictive biomarkers of response to therapy. Understanding the immune cell signatures in the tumor
microenvironment  and  immune  repertoire  changes  is  critical  for  understanding  drug  response.  In  addition  to  DNA,  comprehensive  RNA  expression
information from the tumor is needed to analyze complex pathways that may be activated in the tumor. It is important to identify the increasingly complex
mechanisms  of  tumor  response  and  resistance  to  cancer  therapy,  such  as  neoantigen  burden,  tumor  antigens,  deficient  antigen  presentation,  oncogenic
pathways,  immune  evasion  pathways,  HLA  mutations,  T-cell  clonality,  immune  infiltration,  and  others.  Table  1  describes  some  of  the  biological  gaps  in
current panels. Most of these elements go beyond the capabilities of today’s tumor molecular profiling panels.

Table 1. Most current tumor tissue and liquid biopsy profiling panels miss critical tumor and immune biology.

Fragmented Tumor Molecular Profiling Approaches Result in a Fragmented View of Biology and Limited Insights

With  the  lack  of  a  comprehensive  profiling  solution,  biopharmaceutical  companies  often  turn  to  fragmented,  piecemeal  approaches  to  tumor
molecular  profiling  as  a  stopgap  measure.  Those  fragmented  tumor  molecular  profiling  approaches  lead  to  major  problems  for  therapeutic  development.
Limitations in available tumor samples, including liquid biopsies, force scientists to pick and choose which profiling platforms to include and which to omit,
resulting in a fragmented picture of the biology. Fragmented profiling solutions also result in inconsistent profiling from patient to patient, and clinical trial to
clinical  trial.  This  results  in  data  heterogeneity  that  makes  it  difficult  to  mine  for  new  biological  insights  across  cohorts  of  patients  in  trials.  Finally,  these
piecemeal approaches to tumor molecular profiling result in solutions that often are difficult to use at scale in a clinical or therapeutic setting where logistical
simplicity, cost, turnaround time, and validation are important.

Current Tumor Molecular Profiling Panels Can Become Antiquated with Evolving Science

With the explosion of immunotherapy and advances in our understanding of cancer, new insights into the underlying mechanisms of response and
resistance have emerged. New putative genetic or immune biomarkers of response are regularly identified for different therapies in the context of different
cancers. For instance, new biomarkers have been identified including tumor mutational burden, neoantigens, HLA type, B2M mutations, TGFß, JAK1/JAK2
mutations,  expression  signatures,  cytotoxicity  signatures,  and  T-cell  clonality,  among  others.  A  recent  Nature  Medicine  review  identified  18  different
categories  of  biomarkers  correlating  with  immunotherapy  response  spanning  tumor,  immune  cells,  and  the  tumor  microenvironment.  Due  to  the  limited
coverage of most cancer panels, they may miss new biomarkers. We believe this problem will continue as research uncovers new insights into cancer.

Sequencing Quality and Coverage

Next generation sequencing (“NGS”) is the technological basis for many tumor molecular profiling platforms today. NGS rapidly sequences nucleic
acids  and  then uses a computationally intensive  process  to  reconstruct  gene  sequences  from  millions  of  short  sequence  segments.  These  segments  are
processed in parallel, an approach that greatly increases the speed that the sequence data can be generated. However, because the segments come from
random locations in the genome, reassembling the original sequence is both a technically and computationally challenging process. A key objective is to
ensure  that  every  portion  of  the  genes  being  sequenced  is  covered  by  at  least  one  sequence  segment.  The  average  number  of  sequence  segments
representing a gene is referred to as the sequence depth. The deeper the coverage, the greater fraction of the gene is likely to be covered and the higher
confidence that low-frequency variants can be found.

However,  even  when  sequenced  to  high  depth,  typical  NGS  approaches  can  leave  uneven,  poor  coverage  in  genes  with  mutations  linked  to
cancer and cancer therapy. Many of these regions cannot be fully covered by simply sequencing to higher depth because their sequencing coverage deficits
are due to inherent limitations of the NGS platform. Regions of high guanine-cytosine (“GC”) content or repetitive sequence regions are two such examples
of  regions  that  are  difficult  to  cover  with  standard  NGS  assays.  This  can  leave  gaps  in  coverage  of  therapeutically  important  genes.  This  is  particularly
problematic in cancer, where there can be significant heterogeneity in the tumor samples that can make it even harder to see mutations in regions of poor
coverage.

To address the limitations of typical NGS-based assay, we have developed our patented ACE technology for next-generation sequencing. ACE
improves nucleic acid preparation processes and combines it with patented assay and sequencing methods to achieve superior, high-fidelity, clinical-grade
sequencing quality that ensures high sensitivity for mutations that can inform clinical and therapeutic applications such as neoantigen prediction, biomarker
identification, and novel drug target selection.

Our  NeXT  Platform  uses  our  ACE  technology  to  provide  coverage  of  difficult-to-sequence  gene  regions  across  all  of  the  approximately  20,000
human genes, filling in key gaps left by other NGS approaches. ACE technology provides superior and uniform coverage of difficult genomic regions, such
as  high  GC  content  areas,  and  fills  gaps  and  inconsistencies  in  sequencing  to  achieve  an  optimal  output.  ACE  is  able  to  deliver  more  comprehensive
coverage not by simply generating more data, but by generating higher quality data. We and others have shown in two publications that our ACE technology
achieves superior gene sequencing coverage and finishing.

Commercialization Strategy

We commercialize our products in the United States and Europe through our targeted sales organization. We have also recently begun efforts to
commercialize our products in China. In June 2020, we announced a partnership with a clinical genomics and life sciences company headquartered in China
and our formation of a wholly owned subsidiary in Shanghai. In 2020, we derived substantially all of our revenues from our customers in the United States.
Our sales representatives have extensive experience in enterprise/consultative selling in the genomics space. We augment this team with Ph.D.-level Field
Application  Specialists  that  provide  deep  understanding  and  expertise  in  the  areas  of  oncology  and  genomics  applications,  ensuring  top-quality  pre-  and
post-sales  customer  support.  Our  commercial  efforts  are  focused  on  demonstrating  the  value  proposition  of  the  NeXT  Platform  to  biopharmaceutical
customers  with  the  goal  of  both  increasing  utilization  of  the  product  at  existing  accounts  and  to  drive  adoption  in  new  targeted  accounts.  Our  entire
commercial organization promotes our ability to support biopharmaceutical customers across several application areas including biomarker discovery, new
target discovery, therapy development, and treatment monitoring.

We anticipate that patients in clinical trials for cancer therapies will increasingly be tested pre-treatment and periodically afterwards to understand
response to treatment in deep molecular detail, as their tumors evolve under therapeutic pressure. Although the majority of our revenues come from single
time point testing, we believe our revenues from multiple time point testing will continue to grow. We also derive revenues from analysis of multiple customer
samples from the same patient and time point to assess genetic

14

 
differences between the primary tumor and metastases. Given the value of comprehensive genomic information from multiple time points or samples, we
anticipate that our revenue, and the available market, will continue to grow.

As the clinical utility of advanced biomarkers is further established, we expect there to be a patient-centered diagnostic opportunity whereby some
patients would be guided to personalized therapies. We believe that our platform’s ability to support biomarkers for a broad range of therapeutics positions
us to be a leader in therapy selection for patients.

Our Customers

Our  cancer  genomic  services  are  sold  primarily  to  pharmaceutical  companies,  biopharmaceutical  companies,  biotechnology  companies,
universities,  non-profits,  and  government  entities,  while  services  for  population  sequencing  initiatives  are  sold  primarily  to  the  VA  MVP,  which  is  a
government entity. Our customers include a majority of the top ten oncology-focused pharmaceutical companies, as measured by annual revenues. As of the
end of our fiscal year ended December 31, 2020, 45 customers have placed orders for our NeXT Platform products.

In  2020,  VA  MVP  accounted  for  71%  of  our  revenues.  No  other  customer  accounted  for  10%  or  more  of  our  revenues.  In  2019,  we  had  two
customers account for 10% or more of our revenues: VA MVP at 67% and Pfizer Inc. at 13%. In 2018, we had three customers account for 10% or more of
our revenues: VA MVP at 49%, Merck & Co., Inc. at 12%, and Pfizer Inc. at 10%.

Our Competition

Our principal competition comes from commercial and academic organizations using established and new laboratory tests to produce information
that  is  similar  to  the  information  that  we  generate  for  our  customers.  These  companies  offer  services  that  implement  various  technological  approaches
including next-generation sequencing and microarray analyses. Some of our present or potential competitors include Adaptive Biotechnologies Corporation,
C2i  Genomics,  Inc.,  Caris  Life  Sciences,  Inc.,  Covance  Inc.,  which  was  acquired  by  Laboratory  Corporation  of  America  Holdings  in  February  2015,
Foundation Medicine, Inc., which was acquired by Roche Holdings, Inc. in July 2018, Freenome, Inc., Genosity, Inc., Guardant Health, Inc., Inivata Limited,
Invitae Corporation, Mount Sinai Genomics, Inc. which does business under the name Sema4, Natera, Inc., NanoString Technologies, Inc., NeoGenomics,
Inc., Personal Genome Diagnostics, Inc., Roche Molecular Systems, Inc., and Tempus, Inc.

Additionally,  several  companies  develop  next-generation  sequencing  platforms  that  can  be  used  for  genomic  profiling  for  biopharmaceutical
research and development applications. These include Illumina, Thermo Fisher Scientific Inc., and other organizations that specialize in the development of
next-generation sequencing instrumentation that can be sold directly to biopharmaceutical companies, clinical laboratories, and research centers. Separate
from their instrumentation product lines, both Illumina and Thermo Fisher Scientific Inc., for example, currently market next-generation sequencing clinical
oncology kits that are sold to customers who have bought and operate their respective sequencing instruments.

We believe that we compete favorably because of the integrity and comprehensiveness of the data generated by our NeXT Platform. Maximizing
insights into both the tumor- and immune-related components of the tumor microenvironment is essential in identifying and understanding the reasons why
certain cancer patients respond more favorably to oncology therapies than others. It is via access to such a comprehensive dataset for each patient that our
customers  can  begin  to  discover  new,  clinically  relevant  biomarkers  for  the  immunotherapy  era,  and  ultimately  improve  cancer  patient  outcomes  with  the
development of more efficacious therapeutics.

Intellectual Property

Protection of our intellectual property is fundamental to the long-term success of our business. Specifically, our success is dependent on our ability
to  obtain  and  maintain  proprietary  protection  for  our  technology  and  the  know-how  related  to  our  business,  defend  and  enforce  our  intellectual  property
rights, and operate our business without infringing, misappropriating, or otherwise violating valid and enforceable intellectual property rights of others. We
seek  to  protect  our  investments  made  into  the  development  of  our  technology  by  relying  on  a  combination  of  patents,  trademarks,  copyrights,  trade
secrets, know-how, confidentiality agreements and procedures, non-disclosure agreements with third parties, employee disclosure and invention assignment
agreements, and other contractual rights.

Our  patent  strategy  is  focused  on  seeking  coverage  for  our  core  technology,  our  ACE  assay,  and  specific  follow-on  applications  and
implementations  for  enhancing  sequencing  coverage  of  certain  genomic  regions  and  analyzing  cell-free  nucleic  acids.  In  addition,  we  file  for  patent
protection  on  our  ongoing  research  and  development,  particularly  other  novel  assay  technologies  which  may  be  applicable  in  cancer  cases  and  other
diseases.

Notwithstanding these efforts, we cannot be sure that patents will be granted with respect to any patent applications we have filed or may license
or file in the future, and we cannot be sure that any patents we have or may be licensed or granted to us in the future, will not be challenged, invalidated, or
circumvented, or that such patents will be commercially useful in protecting our technology. Moreover, we rely, in part, on trade secrets to protect aspects of
our business that are not amenable to, or that we do not consider appropriate for, patent protection. However, trade secrets can be difficult to protect. While
we  take  steps  to  protect  and  preserve  our  trade  secrets,  including  by  entering  into  confidentiality  agreements  with  our  employees,  consultants,  scientific
advisors, and contractors, conducting an annual training for our employees to increase awareness of cybersecurity threats, and maintaining physical security
of  our  premises  and  physical  and  electronic  security  of  our  information  technology  systems,  such  measures  can  be  breached,  and  we  may  not  have
adequate remedies for any such breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. For
more information regarding the risks related to our intellectual property, please see “Risk Factors—Intellectual Property Risks.”

additional  term  for  patent  term  adjustments  or  patent  term  extensions.  If  patents  are  issued  on  our  pending  patent  applications,  the  resulting  patents  are
projected to expire on dates ranging from 2033 to 2040.

Government Regulations

Federal and State Laboratory Licensing Requirements

Under  the  CLIA,  a  laboratory  is  any  facility  that  performs  laboratory  testing  on  specimens  derived  from  humans  for  the  purpose  of  providing
information  for  the  diagnosis,  prevention  or  treatment  of  disease,  or  the  impairment  of  or  assessment  of  health.  CLIA  requires  that  a  laboratory  hold  a
certificate  applicable  to  the  type  of  laboratory  examinations  it  performs  and  that  it  complies  with,  among  other  things,  standards  covering  operations,
personnel, facilities administration, quality systems and proficiency testing, which are intended to ensure, among other things, that clinical laboratory testing
services are accurate, reliable and timely.

To renew our CLIA certificate, we are subject to survey and inspection every two years to assess compliance with program standards. Because
we are a CAP accredited laboratory, the Centers for Medicare & Medicaid Services (“CMS”) does not perform this survey and inspection and relies on our
CAP survey and inspection. We also may be subject to additional unannounced inspections. Laboratories performing high complexity testing are required to
meet more stringent requirements than laboratories performing less complex tests. In addition, a laboratory that is certified as “high complexity” under CLIA
may develop, manufacture, validate, and use proprietary tests referred to as laboratory developed tests (“LDTs”). CLIA requires analytical validation including
accuracy,  precision,  specificity,  sensitivity,  and  establishment  of  a  reference  range  for  any  LDT  used  in  clinical  testing.  The  regulatory  and  compliance
standards applicable to the testing we perform may change over time, and any such changes could have a material effect on our business.

CLIA provides that a state may adopt laboratory regulations that are more stringent than those under federal law, and a number of states have
implemented their own more stringent laboratory regulatory requirements. State laws may require that nonresident laboratories, or out-of-state laboratories,
maintain an in-state laboratory license to perform tests on samples from patients who reside in that state. As a condition of state licensure, these state laws
may  require  that  laboratory  personnel  meet  certain  qualifications,  specify  certain  quality  control  procedures  or  facility  requirements,  or  prescribe  record
maintenance  requirements.  Because  our  laboratory  is  located  in  the  state  of  California,  we  are  required  to  and  do  maintain  a  California  state  laboratory
license.  We  also  maintain  licenses  to  conduct  testing  in  other  states  where  nonresident  laboratories  are  required  to  obtain  state  laboratory  licenses.  We
maintain  a  current  license  with  the  New  York  State  Department  of  Health  for  our  laboratory.  Other  states  may  currently  have  or  adopt  similar  licensure
requirements in the future, which may require us to modify, delay, or stop its operations in those states.

Regulatory framework for medical devices in the United States

Pursuant to its authority under the Federal Food, Drug and Cosmetic Act (the “FDC Act”), the FDA has jurisdiction over medical devices, which are
defined to include, among other things, in vitro diagnostic devices (“IVDs”). The FDA regulates, among other things, the research, design, development, pre-
clinical  and  clinical  testing,  manufacturing,  safety,  effectiveness,  packaging,  labeling,  storage,  recordkeeping,  pre-market  clearance  or  approval,  adverse
event reporting, marketing, promotion, sales, distribution, and import and export of medical devices. Unless an exemption applies, each new or significantly
modified medical device we seek to commercially distribute in the United States will require either a premarket notification to the FDA requesting permission
for commercial distribution under Section 510(k) of the FDC Act, also referred to as a 510(k) clearance, or approval from the FDA of a PMA. Both the 510(k)
clearance and PMA processes can be resource intensive, expensive, and lengthy, and require payment of significant user fees.

Although  the  FDA  regulates  medical  devices,  including  IVDs,  the  FDA  has  historically  exercised  its  enforcement  discretion  and  not  enforced
applicable provisions of the FDC Act and FDA regulations with respect to LDTs, which are a subset of IVDs that are intended for clinical use and developed,
validated, and offered within a single laboratory for use only in that laboratory. We market our diagnostic test based on the NeXT Platform as an LDT. As a
result, we believe our diagnostic services are not currently subject to the FDA’s enforcement of its medical device regulations and the applicable FDC Act
provisions.

16

 
 
 
 
 
Federal and State Fraud and Abuse Laws

We are subject to federal fraud and abuse laws such as the federal Anti-Kickback Statute (the “AKS”), the federal prohibition against physician
self-referral (the “Stark Law”), and the federal false claims law, or the False Claims Act (the “FCA”). We are also subject to similar state and foreign fraud and
abuse laws.

The AKS prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration, directly or indirectly, overtly or
covertly, in cash or in kind, in return for or to induce such person to refer an individual, or to purchase, lease, order, arrange for, or recommend purchasing,
leasing, or ordering, any good, facility, item, or service that is reimbursable, in whole or in part, under a federal healthcare program.

The Stark Law and similar state laws, including California’s Physician Ownership and Referral Act, generally prohibit, among other things, clinical
laboratories and other entities from billing a patient or any governmental or commercial payer for any diagnostic services when the physician ordering the
service, or any member of such physician’s immediate family, has a direct or indirect investment interest in or compensation arrangement with us, unless the
arrangement meets an exception to the prohibition.

Other federal fraud and abuse laws to which we are subject include, but are not limited to, the federal civil and criminal false claims laws including
the FCA, which imposes liability on any person or entity that, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim
for  payment  to  the  federal  government,  and  the  federal  Civil  Monetary  Penalties  Law,  which  prohibits,  among  other  things,  the  offering  or  transfer  of
remuneration to a Medicare or state healthcare program beneficiary if the person knows or should know it is likely to influence the beneficiary’s selection of a
particular provider, practitioner, or supplier of services reimbursable by Medicare or a state healthcare program, unless an exception applies. Under the FCA,
private citizens can bring claims on behalf of the government through qui tam actions. We must also operate within the bounds of the fraud and abuse laws
of the states in which we do business which may apply to items or services reimbursed by non-governmental third-party payers, including private insurers.

Efforts  to  ensure  that  our  business  arrangements  with  third  parties  will  comply  with  applicable  healthcare  laws  and  regulations  will  involve
substantial costs. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be
subject  to  significant  civil,  criminal  and  administrative  penalties,  damages,  fines,  imprisonment,  exclusion  from  government-funded  healthcare  programs,
such  as  Medicare  and  Medicaid,  disgorgement,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings,  additional  reporting,  or
oversight obligations if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with the law and
the curtailment or restructuring of our operations. If any of the physicians or other healthcare providers or entities with whom we do business is found to be
not in compliance with applicable laws, they may be subject to significant criminal, civil or administrative sanctions, including exclusions from government-
funded healthcare programs.

HIPAA and HITECH

Under the administrative simplification provisions of the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), as amended by the
Health  Information  Technology  for  Economic  and  Clinical  Health  Act  (“HITECH”),  the  U.S.  Department  of  Health  and  Human  Services  (“HHS”)  issued
regulations that establish uniform standards governing the conduct of certain electronic healthcare transactions and requirements for protecting the privacy
and  security  of  protected  health  information  (“PHI”),  used  or  disclosed  by  covered  entities  and  business  associates.  Covered  entities  and  business
associates  are  subject  to  HIPAA  and  HITECH.  Our  subcontractors  that  create,  receive,  maintain,  transmit,  or  otherwise  process  PHI  on  behalf  of  us  are
HIPAA “business associates” and must also comply with HIPAA as a business associate.

HIPAA and HITECH include privacy and security rules, breach notification requirements, and electronic transaction standards.

The Privacy Rule covers the use and disclosure of PHI by covered entities and business associates. The Privacy Rule generally prohibits the use
or disclosure of PHI, except as permitted under the Rule. The Privacy Rule also sets forth individual patient rights, such as the right to access or amend
certain records containing his or her PHI, or to request restrictions on the use or disclosure of his or her PHI.

The  Security  Rule  requires  covered  entities  and  business  associates  to  safeguard  the  confidentiality,  integrity,  and  availability  of  electronically
transmitted or stored PHI by implementing administrative, physical, and technical safeguards. Under HITECH’s Breach Notification Rule, a covered entity
must notify individuals, the Secretary of the HHS, and in some circumstances, the media of breaches of unsecured PHI.

In  addition,  we  may  be  subject  to  state  health  information  privacy  and  data  breach  notification  laws,  which  may  govern  the  collection,  use,
disclosure, and protection of health-related and other personal information. California, for example, has enacted the Confidentiality of Medical Information
Act, which sets forth standards in addition to HIPAA and HITECH with which all California health care providers like us must abide. State laws may be more
stringent,  broader  in  scope,  or  offer  greater  individual  rights  with  respect  to  PHI  than  HIPAA,  and  state  laws  may  differ  from  each  other,  which  may
complicate compliance efforts.

Entities that are found to be in violation of HIPAA as the result of a failure to secure PHI, a complaint about our privacy practices or an audit by
HHS,  may  be  subject  to  significant  civil  and  criminal  fines  and  penalties  and  additional  reporting  and  oversight  obligations  if  such  entities  are  required  to
enter into a resolution agreement and corrective action plan with HHS to settle allegations of HIPAA non-compliance.

U.S. Healthcare Reform

In the United States, there have been a number of legislative and regulatory changes at the federal and state levels that seek to reduce healthcare
costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care
and Education Reconciliation Act (collectively, the “ACA”), became law. This law substantially changed the way health care is financed by both commercial
payers and government payers, and significantly impacted our industry. The ACA contained a number of provisions expected to impact the clinical laboratory
industry, such as changes governing enrollment in state and federal health care programs, reimbursement changes, and fraud and abuse.

Some of the provisions of the ACA have yet to be implemented, and there have been judicial and Congressional challenges to certain aspects of
the ACA, as well as recent efforts by the former Trump administration to repeal or replace certain aspects of the ACA. Since January 2017, former President
Trump  signed  two  executive  orders  and  other  directives  designed  to  delay  the  implementation  of  certain  provisions  of  the  ACA.  Concurrently,  Congress
considered legislation that would repeal, or repeal and replace, all or part of the ACA. While Congress has not passed comprehensive repeal legislation, it
has enacted laws that modify certain provisions of the ACA such as removing penalties, starting January 1, 2019, for not complying with the ACA’s individual
mandate  to  carry  health  insurance  and  delaying  the  implementation  of  certain ACA-mandated  fees.  On  December  14,  2018,  a  Texas  U.S.  District  Court
Judge ruled that the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act
of  2017.  While  the  Texas  U.S.  District  Court  Judge,  as  well  as  the  Trump  administration  and  CMS,  stated  that  the  ruling  will  have  no  immediate  effect
pending appeal of the decision, it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA.

We anticipate there will continue to be proposals by legislators at both the federal and state levels, regulators and commercial payers to reduce
costs while expanding individual healthcare benefits. Certain of these changes could impose additional limitations on the prices we will be able to charge for
our tests, the coverage of or the amounts of reimbursement available for our tests from payers, including commercial payers and government payers.

Material Agreements

VA MVP Agreement

On September 28, 2017, we entered into a contract with the VA for the VA MVP to provide them with a combination of whole genome sequencing
services (the “VA MVP Agreement”). The performance period for the services includes a base period of one year (September 2017 through August 2018),
with three one-year renewal option periods that may be exercised upon discretion of the VA MVP (September 2018 through August 2019; September 2019
through  August  2020;  and  September  2020  through  August  2021).  Each  task  order  issued  against  the  VA  MVP  Agreement  has  a  separate  period  of
performance and is subject to the terms and conditions of the VA MVP Agreement. Funds are obligated by the VA MVP under each task order based on
actual  needs.  To  date,  the  VA  MVP  has  exercised  all  of  its  three  one-year  renewal  options,  meaning  that  the  VA  MVP  Agreement  expires  at  the  end  of
August 2021 and there are no remaining renewal options. Our current task order extends through August 2021. In order for us to provide additional services
to the VA MVP after August 2021, we would need to receive an additional task order before the VA MVP Agreement expires in September 2021, or enter into
a new services agreement with the VA MVP.

All  materials  and  samples  utilized  during  the  course  of  the  VA  MVP  Agreement  and  all  data  first  produced  or  delivered  under  the  VA  MVP
Agreement are the sole property of the VA MVP. Under the VA MVP Agreement, we are subject to confidentiality and security obligations, as well as various
obligations upon events of default.

The VA MVP may terminate the VA MVP Agreement, or any part thereof, at its sole convenience. Subject to the terms of the VA MVP Agreement,
we  shall  be  paid  a  percentage  of  the  contract  price  reflecting  the  percentage  of  the  work  performed  prior  to  the  notice  of  termination,  plus  reasonable
charges that we can demonstrate have resulted from the termination.

The VA MVP may terminate the VA MVP Agreement, or any part thereof, for cause in the event of any default by us, or if we fail to comply with
any contract terms and conditions, or fail to provide the VA MVP, upon request, with adequate assurances of future performance. In the event of termination
for cause, the VA MVP shall not be liable to us for any amount for supplies or services not accepted, and we shall be liable to the VA MVP for any and all
rights and remedies provided by law. If it is determined that the VA MVP improperly terminated this contract for default, such termination shall be deemed a
termination for convenience.

Agreements with Illumina

On March 1, 2019, we received a quotation for supply of genetic analysis products (the “Quote”) from Illumina. The Quote provided information as
to  the  cost  of  five  NovaSeqTM6000  Sequencing  System  instruments.  The  term  of  the  Quote  extended  through  March  31,  2019.  On  March  20,  2019,  we
submitted a purchase order to Illumina for five NovaSeqTM6000 Sequencing System instruments, four of which we have received and one of which will be
received on or before the due date of March 23, 2023.

On November 1, 2017, we entered into a master services subcontract agreement (the “Subcontract Agreement”) with Illumina. Under the terms of
the  Subcontract  Agreement,  we  engaged  Illumina  as  our  subcontractor  to  perform  certain  genotyping  services  (the  “Services”) on  our  behalf  pursuant  to
written purchase orders in fulfillment of our VA MVP Agreement. The price for Illumina’s Services set forth in the Subcontract Agreement is effective through
December 31, 2021, or later if the VA MVP Agreement is extended.

18

The Subcontract Agreement extends through the last day of the VA MVP Agreement, currently August 2021 but as may be extended, unless it is
otherwise terminated early pursuant to its terms. All or part of the Subcontract Agreement may be terminated at our convenience in the event that the VA
MVP terminates the VA MVP Agreement or terminates the part of the VA MVP Agreement that affects the Services provided by Illumina. Each party may
terminate  the  Subcontract  Agreement  for  default  in  the  event  that  the  other  party  materially  fails  to  perform  any  of  the  provisions  of  the  Subcontract
Agreement,  materially  fails  to  make  progress  so  as  to  endanger  performance  of  the  Subcontract  Agreement  in  accordance  with  its  terms, or  becomes
financially or legally incapable of completing the work and does not provide a plan of correction or recovery within the provided period of time to cure such
failure. The Subcontract Agreement may be renewed for subsequent one-year terms as agreed by the parties subject to a four-year limit.

On March 26, 2019, we entered into a pricing agreement with Illumina, which provides pricing terms for the NovaSeq™ 5000/6000 S4 Reagent Kit
(each, a “Kit”). The pricing agreement had a purchase commitment of $1.7 million by June 30, 2019 to purchase these Kits, which we fulfilled in the ordinary
course of business. The term of the pricing agreement extends through December 31, 2022.

From time to time, we receive quotations for supply of genetic analysis products from Illumina that provide for pricing terms on Illumina products

outside of those discussed above.

Human Capital Management within Our Company

We recognize that our employees are both our most valuable asset and our most important investment. The success of our organization is reliant

upon each individual’s significant contribution to our corporate culture and goals. Following is a list of our core company values:

•
•
•
•
•
•

Integrity
Respect
Teamwork and collaboration
Commitment to scientific excellence
Dedication to discovery and innovation
Passion

We understand that our future depends upon the attraction, retention, and engagement of a talented, diverse, and committed team that can thrive
and  innovate  in  a  supportive  and  safe  environment.  Our  efforts  to  ensure  this  occurs  across  the  enterprise  include  offering  competitive  total  rewards
programs,  ongoing  training  and  development,  commitment  to  the  safety  and  health  of  our  employees,  and  support  for  our  employees  during  the
unprecedented global circumstances that began in 2020.

Many of our insights and adaptations during 2020 related to the hiring and support of our employees are expected to be continued through 2021.
These  include  additional  outreach  and  enhanced  communication  by  our  leadership  and  employees  at  multiple  levels  and  support  for  more  flexible  work
plans.

At  a  foundational  level,  employees  receive  training  related  to  workplace  safety  and  emergency  preparedness,  awareness  and  expectations  of
inclusion  and  diversity,  required  data  protection,  and  other  regulatory  matters.  Our  Diversity  Committee  identifies  learnings  employees  can  benefit  from
including insights from employees with different backgrounds and opportunities to actively contribute at work and in our communities to support diversity and
inclusiveness. As an example, we have made visible the contributions of various groups to the science that informs our work at Personalis.

We believe engagement and retention is especially critical at Personalis given the complex and highly technical nature of our work. Successfully
onboarding new employees involves a significant commitment from managers and fellow employees. Retaining newly hired team members is also critical
given  the  relatively  small  number  of  applicants  who  meet  our  requirements  and  the  competitive  market  for  such  talent.  Our  approach  involves  ongoing
internal  and  external  reviews  and  benchmarking  of  the  competitiveness  of  our  offerings,  including  in  the  following  areas:  cash  and  equity  compensation,
benefits, workplace flexibility, and career growth and development opportunities. As a company with significant growth plans, we expect to continue not only
with  our  current  efforts,  but  to  broaden  them  with  input  from  employees  and  managers,  as  well  as  comparisons  with  others  in  our  industries  and  other
sectors.

As of December 31, 2020, we had 235 employees, 234 of whom were full-time employees. Of these full-time employees, 96 were in research and
development,  60  in  laboratory  operations,  44  in  commercial  operations,  and  34  in  general  and  administrative  functions.  At  this  time,  227  of  our  full-time
employees are in the United States (including 208 who are based out of our corporate headquarters in Menlo Park, California), six of our full-time employees
are in Europe, and one of our full-time employees is in China. As of December 31, 2020, more than 95 of our employees had completed a Ph.D. or other
advanced science or medical degree.

None of our employees are represented by a labor union or covered by collective bargaining agreements, and we have not experienced any work

stoppages. We consider our relations with our employees to be good.

Item 1A. Risk Factors.

Summary of Risk Factors

The following is a summary of the principal risks and uncertainties that could materially adversely affect our business, financial condition, or results

of operations. You should read this summary together with the more detailed description of risk factors below under the heading “Risk Factors”.

Operational, Strategic and Business Risks

•

•

•

•

•

•

•

•

•

•

•

•

•

We  have  a  history  of  losses  and  we  expect  to  incur  significant  losses  for  the  foreseeable  future  and  may  not  be  able  to  generate  sufficient
revenues to achieve or sustain profitability.

If we are unable to increase sales of our current services or products or successfully develop and commercialize other services or products, or are
unable to successfully compete with our competitors, we may fail to generate sufficient revenues to achieve profitability and sustain our business.

Our  operations  and  employees  face  risks  related  to  health  crises,  such  as  the  ongoing  COVID-19  pandemic,  that  could  adversely  affect  our
operations, our financial condition, and our operations results, and the business or operations of our customers or other third parties with whom we
conduct business.

A  limited  number  of  customers  account  for  a  substantial  portion  of  our  revenues  and  accounts  receivable;  in  particular,  we  derive  a  substantial
portion of our revenues from our largest customer, the VA MVP.

We rely on a limited number of suppliers, or in some cases, a sole supplier, for some laboratory instruments and materials, and we may not be
able to replace or immediately transition to alternative suppliers if necessary.

We  will  need  to  invest  in  our  infrastructure  in  advance  of  increased  demand  for  our  services;  our  failure  to  accurately  forecast  demand  would
negatively impact our business and ability to achieve or sustain profitability.

If our facilities become damaged or inoperable, or we are required to vacate the facilities, our ability to sell and provide our services and pursue
our research and development efforts may be jeopardized.

If we cannot continue timely developing and improving our services and products to keep pace with rapid advances in technology, medicine, and
science our operating results and competitive position could be harmed.

Personalized  cancer  therapies  represent  new  therapeutic  approaches  that  could  result  in  heightened  regulatory  scrutiny,  delays  in  clinical
development, or delays in our inability to achieve regulatory approval, commercialization, or payor coverage, any of which could adversely affect
our business.

The loss of key members of our executive management team or the inability to hire, retain, or motivate highly skilled personnel could adversely
affect our business.

We may not be able to manage our growth effectively, which could prevent execution of our business strategy.

We may acquire businesses or assets, form joint ventures, or make investments in other companies or technologies that could harm our operating
results, dilute stockholders’ ownership, or cause us to incur debt or significant expense.

Expansion into China and other international markets will subject us to increased regulatory oversight and regulatory, economic, social, health and
political uncertainties.

Regulatory, Legal and Cybersecurity Risks

•

•

•

•

Complying  with  numerous  statutes  and  regulations  pertaining  to  our  business  is  an  expensive  and  time-consuming  process,  and  we  may  be
subject to regulatory action if we or our service or product offerings do not comply with applicable requirements.

Our internal information technology systems, or those of our third-party vendors, contractors, or consultants, may fail or suffer security breaches,
loss or leakage of data, and other disruptions, which could adversely affect our business.

The actual or perceived failure by us, our customers, or vendors to comply with increasingly stringent laws, regulations and contractual obligations
relating to privacy, data protection, and data security could harm our reputation, and subject us to significant fines and liability.

Our  employees  may  engage  in  misconduct  or  other  improper  activities,  such  as  noncompliance  with  regulatory  standards  and  requirements,
including  the  Foreign  Corrupt  Practices  Act  of  1977  and  other  anti-bribery  laws,  which  could  cause  significant  liability  for  us  and  harm  our
reputation.

•

•

Changes in health care policy could increase our costs, decrease our revenues, and impact sales of and reimbursement for our tests. If we decide
to grow our business by developing in vitro diagnostic tests, we may be subject to reimbursement challenges.

The exit of the United Kingdom from the EU could lead to regulatory divergence and require us to incur additional expenses in order to develop,
manufacture, and commercialize our products and services.

Intellectual Property Risks

•

•

•

•

•

•

Litigation  or  other  proceedings  or  claims  of  intellectual  property  infringement,  misappropriation,  breach  of  license  terms  or  other  violations  may
require us to spend significant time and money, including damages, and could prevent us from selling our tests.

If we cannot license rights to use necessary technologies on reasonable terms, we may not be able to commercialize new products.

If  we  are  not  able  to  obtain,  maintain  and  enforce  patent  protection  for  our  products,  services  or  technologies,  our  competitors  and  other  third
parties  could  develop  and  commercialize  products,  services  and  technologies  similar  or  identical  to  ours,  and  our  ability  to  successfully
commercialize our products, services, and technologies may be adversely affected.

If we are unable to protect the confidentiality of our trade secrets and know-how, our business would be harmed.

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

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and
our business may be adversely affected.

Financial and Market Risks and Risks Related to Owning Our Common Stock

•

•

•

•

•

•

•

•

•

•

•

Certain of our customers prepay us for a portion of the future services that they expect to order and we may be required to refund some or all of
those prepayments in the event of a cancellation or a reduction of services.

Our inability to raise additional capital on acceptable terms may adversely affect operations or expansion.

The market price of our common stock may be volatile or may decline steeply or suddenly regardless of our operating performance, we may not
be able to meet investor or analyst expectations, and you may lose all or part of your investment.

Our quarterly results may fluctuate significantly, which could adversely impact our common stock’s value.

Insiders may exercise significant control over our company and will be able to influence corporate matters.

Sales of shares by existing stockholders, the perception that such sales could occur, or future sales and issuances by us of our common stock or
rights to purchase common stock could cause the stock price of our common stock to decline.

Achieving a return on your investment will depend on appreciation of the value of our common stock.

If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research about our
business, our stock price and trading volume could decline.

Our ability to use net operating losses to offset future taxable income may be subject to limitations.

Delaware law and provisions in our amended and restated certificate of incorporation and amended and restated bylaws could make a merger,
tender  offer,  or  proxy  contest  difficult,  thereby  depressing  the  trading  price  of  our  common  stock;  our  amended  and  restated  certificate  of
incorporation has an exclusive forum provision, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or
our directors, officers, or employees.

Material  weaknesses  in  our  internal  control  over  financial  reporting  may  cause  us  to  fail  to  timely  and  accurately  report  our  financial  results  or
result in a material misstatement of our financial statements. Our disclosure controls and procedures may not prevent or detect all errors or acts of
fraud.

Risk Factors.

Our operations and financial results are subject to various risks and uncertainties including those described below. You should consider carefully
the risks and uncertainties described below, in addition to other information contained in this Annual Report on Form 10-K, including our audited consolidated
financial statements and related notes. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties that we
are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. If any of the following
risks or others not specified below materialize, our business, financial condition, and results of operations could be materially and adversely affected. In that
case, the trading price of our common stock could decline.

Operational, Strategic and Business Risks

We have a history of losses, and as our costs increase, we expect to incur significant losses for the foreseeable future and may not be
able to generate sufficient revenues to achieve or sustain profitability.

We have incurred net losses since our inception. For the years ended December 31, 2020, 2019, and 2018 we had net losses of $41.3 million,
$25.1 million, and $19.9 million, respectively. As of December 31, 2020, we had an accumulated deficit of $181.9 million. To date, we have not generated
sufficient revenues to achieve profitability, and we may never achieve or sustain profitability. In addition, we expect to continue to incur net losses for the
foreseeable future, and we expect our accumulated deficit to continue to increase as we focus on scaling our business and operations. Our efforts to sustain
and  grow  our  business  may  be  more  costly  than  we  expect,  and  we  may  not  be  able  to  increase  our  revenues  sufficiently  to  offset  our  higher  operating
expenses. Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity and working capital.
Our failure to achieve and sustain profitability in the future would negatively affect our business, financial condition, results of operations, and cash flows, and
could cause the market price of our common stock to decline.

If we are unable to increase sales of our current services or successfully develop and commercialize other services or products, or if
we are unable to execute our sales and marketing strategy for our services or unable to gain sufficient acceptance in the market, we
may fail to generate sufficient revenues to achieve profitability and sustain our business.

We currently derive substantially all of our revenues from sales of our services. We began offering our services through our Clinical Laboratory
Improvement Amendments of 1988 (“CLIA”)-certified, College of American Pathologists (“CAP”)-accredited, and state-licensed laboratory in 2013. We are in
varying stages of research and development for other services and products that we may offer. If we are unable to increase sales of our existing services or
successfully develop and commercialize other services and products, we will not generate sufficient revenues to become profitable.

In addition, as a growing genomics company, we have engaged in targeted sales and marketing activities for our services. Although we have had
revenues from sales of our services since 2013, our services may never gain significant acceptance in the marketplace and therefore may never generate
substantial revenues or permit us to become profitable. We will need to further establish and grow the market for our services through the expansion of our
current  relationships  and  development  of  new  relationships  with  biopharmaceutical  customers.  Gaining  acceptance  in  medical  communities  can  be
supported by, among other things, publications in leading peer-reviewed journals of results from studies using our services. The process of publication in
leading medical journals is subject to a peer review process and peer reviewers may not consider the results of our studies sufficiently novel or worthy of
publication. Failure to have our studies published in peer-reviewed journals would limit the adoption of our services.

Our ability to successfully market our services that we have developed, and may develop in the future, will depend on numerous factors, including:

•

•

•

•

•

•

•

•

our ability to demonstrate the utility and value of our services to our customers;

the success of our commercial team, including sales and business development personnel;

the recruitment, hiring, and retention of our commercial team personnel;

whether biopharmaceutical companies accept that our services are sufficiently sensitive and specific;

our ability to convince biopharmaceutical companies of the utility of the comprehensiveness of our services and of testing patients at multiple
time points;

our ability to continue to fund sales and marketing activities;

whether our services are considered superior to those of our competitors;

any negative publicity regarding our or our competitors’ services resulting from defects or errors;

23

 
 
 
 
 
 
 
 
 
•

•

our success obtaining and maintaining patent and trade secret protection for our services and technologies; and

our success enforcing and defending intellectual property rights and claims.

Failure to achieve broad market acceptance of our services would materially harm our business, financial condition, and results of operations.

Our operations and employees face risks related to health crises, such as the ongoing COVID-19 pandemic, that could adversely affect
our  financial  condition  and  operating  results.  The  COVID-19  pandemic  could  materially  affect  our  operations,  including  at  our
headquarters  in  the  San  Francisco  Bay  Area,  which  is  currently  subject  to  restrictive  orders,  and  the  business  or  operations  of  our
customers or other third parties with whom we conduct business.

Our business could be adversely impacted by the effects of a health crisis, such as the ongoing COVID-19 pandemic, that could cause significant
disruption in the operations of our customers and third-party suppliers upon whom we rely. Our laboratory facilities (other than the facilities being developed
for our use in Shanghai, China), executive team, and most of our employees are located in the San Francisco Bay Area. In the event of a health crisis that
becomes widespread in or around the San Francisco Bay Area, we may proactively, or be ordered by government officials to, take precautionary measures
such as suspending our lab operations, implementing alternative work arrangements for our employees, and limiting our employees’ travel activities.

Our operations have been impacted by the ongoing COVID-19 pandemic. While the state and county reopening and health orders applicable to us
allow  for  continued  operation  of  so-called  Essential  Businesses,  which  includes  certain  critical  healthcare  operations  and  services,  we  have  substantially
closed  our  office  facilities  and  limited  access  to  our  laboratory  facilities  to  protect  our  employees  and  to  comply  with  the  provisions  described  within  the
orders.  We  provided  temporary  increased  pay  to  certain  laboratory  personnel  in  the  second  quarter  for  their  work  during  the  COVID-19  pandemic.  Such
increased pay was not provided in the third or fourth quarters, but we may decide to resume increased pay in the future. The previous shelter-in-place order
and current reopening and health orders have negatively impacted productivity, disrupted our business, and slowed research and development activities due
to us limiting access to our laboratory space that would otherwise be used by our research and development group, and, to the extent such orders remain in
place,  they  may  continue  to  cause  such  effects  on  our  operations.  The  reopening  and  health  orders  may  disrupt  the  ability  of  our  suppliers  to  fulfill  our
purchase orders in a timely manner or at all. Additionally, we are aware of increased demand in the market for certain consumables used in COVID-19 test
kits.  We  use  such  consumables  in  our  operations,  and  we  may  face  difficulties  in  acquiring  such  consumables  if  our  suppliers  prioritize  orders  related  to
COVID-19.  Several of our customers, including the  VA  MVP,  were  delayed  in  sending  us  samples  in  the  second  and  third  quarters  due  to  the  inability  to
collect or ship samples during the COVID-19 pandemic, and these and additional customers may be disrupted from collecting samples or sending purchase
orders and samples to us in the future. Many of our customers, potential customers and potential partners have also put in place policies restricting visitors
from other companies, and therefore our sales team and members of management have been unable to meet such parties in person, which may result in
reduced acquisition of new customers, fewer orders from existing customers, and fewer potential partnering opportunities. If our laboratory employees were
to contract COVID-19, we may significantly curtail our laboratory operations or pause operations altogether until the imminent health risk to our employees
subsided. Such disruptions in our operations, and our customers’ and suppliers’ operations, may continue to adversely affect revenues and operating results.

The  global  COVID-19  pandemic  continues  to  rapidly  evolve  and  to  present  serious  health  risks.  While  authorities  in  some  areas  have  lifted  or
relaxed certain of the restrictions described above, in some cases they have subsequently re-imposed various restrictions after observing an increased rate
of COVID-19 cases; for example, in December 2020, state and local authorities in California reinstated shelter-in-place orders in light of the increasing rate
of  COVID-19  cases  and  shortage  of  intensive  care  unit  beds  across  the  state.  Furthermore,  there  is  no  guarantee  when  or  if  all  such  restrictions  will  be
eliminated,  such  that  we  and  our  customers,  manufacturers  and  suppliers  will  be  able  to  safely  resume  operations  consistent  with  our  pre-COVID-19
operations. Vaccines against COVID-19 have been approved by the FDA and other regulatory authorities, but there is uncertainty as to when these vaccines
will be widely available to our employees and the population at large and how quickly and to what extent the vaccines will impact the COVID-19 pandemic.

While the extent of the impact of the current COVID-19 pandemic on our business and financial results is uncertain, a continued and prolonged

public health crisis such as the COVID-19 pandemic could have a material negative impact on our business, financial condition, and operating results.

If we cannot compete successfully with our competitors, we may be unable to increase or sustain our revenues or achieve and sustain
profitability.

Our principal competition comes from commercial and academic organizations using established and new laboratory tests to produce information
that is similar to the information that we generate for our customers. These commercial and academic organizations may not utilize our services or may not
believe them to be superior to those tests that they currently use or others that are developed. Further, it may be difficult to convince our customers to use
our comprehensive test rather than simpler panels provided by our competitors. For example, the information that we provide may be more challenging or
require additional resources for our customers to interpret than the information provided by our competitors’ less comprehensive assays.

Some  of  our  present  or  potential  competitors,  including  Adaptive  Biotechnologies  Corporation,  C2i  Genomics,  Inc.,  Caris  Life  Sciences,  Inc.,
Covance  Inc.,  which  was  acquired  by  Laboratory  Corporation  of  America  Holdings  in  February  2015,  Foundation  Medicine,  Inc.,  which  was  acquired  by
Roche Holdings, Inc. in July 2018, Freenome, Inc., Genosity, Inc., Guardant Health, Inc., Inivata

24

 
 
 
Limited,  Invitae  Corporation,  Mount  Sinai  Genomics,  Inc.  which  does  business  under  the  name  Sema4,  Natera,  Inc.,  NanoString  Technologies,  Inc.,
NeoGenomics, Inc., Personal Genome Diagnostics, Inc., Roche Molecular Systems, Inc., and Tempus, Inc., may have more widespread brand recognition or
substantially  greater  financial  or  technical  resources,  development  or  production  capacities,  or  marketing  capabilities  than  we  do.  They  may  be  able  to
devote  greater  resources  to  the  development,  promotion  and  sale  of  their  products  and  services  than  we  do  or  sell  their  products  and  services  at  prices
designed to win more significant levels of market share. In addition, our present or potential competitors may be acquired by, receive investments from, or
enter into other commercial relationships with larger, more well-established and well-financed companies. For example, in September 2020, Illumina, Inc.
(“Illumina”)  announced  it  had  entered  into  an  agreement  to  acquire  GRAIL,  Inc.  (“GRAIL”),  a  company  focused  on  early  cancer  detection  and  potentially
other forms of cancer analysis using next-generation sequencing technology, which we view as a potential competitor. Others may develop lower-priced, less
complex products and services that pharmaceutical companies could view as functionally equivalent to our current or planned future services which could
force us to lower the price of our services and impact our operating margins and our ability to achieve and maintain profitability. In addition, companies or
governments that control access to genetic testing and related services through umbrella contracts or regional preferences could promote our competitors or
prevent us from performing certain services. In addition, technological innovations that result in the creation of enhanced products or diagnostic tools that are
more  sensitive  or  specific  than  ours  may  enable  other  clinical  laboratories,  hospitals,  physicians,  or  medical  providers  to  provide  specialized  products  or
services similar to  ours  in  a  more  patient-friendly,  efficient,  or  cost-effective  manner  than  is  currently  possible.  If  we  cannot  compete  successfully  against
current or future competitors, we may be unable to ensure or increase market acceptance and sales of our current or planned future services, which could
prevent us from increasing or sustaining our revenues or achieving or sustaining profitability.

We expect that biopharmaceutical companies will increasingly focus attention and resources on the targeted and personalized cancer diagnostic
sector as the potential and prevalence of molecularly targeted oncology therapies approved by the U.S. Food and Drug Administration (the “FDA”) along with
companion diagnostics increases. For example, the FDA has approved several such targeted oncology therapies that use companion diagnostics, including
the anaplastic lymphoma kinase FISH test from Abbott Laboratories, Inc. for use with Xalkori® from Pfizer Inc., the BRAF kinase V600 mutation test from
Roche Molecular Systems, Inc. for use with Zelboraf® from Daiichi-Sankyo/Genentech/Roche, and the BRAF kinase V600 mutation test from bioMerieux for
use with Tafinlar® from GlaxoSmithKline. Since companion diagnostic tests are part of FDA labeling, non-FDA cleared tests, such as the ones we currently
offer  as  part  of  our  services,  would  be  considered  an  off-label  use  and  this  may  limit  our  access  to  this  market  segment.  Our  customers  and  potential
customers  may  request,  or  in  some  cases  have  requested,  that  we  consider  developing  and  seeking  FDA  approval  for  companion  diagnostic  tests  to
accompany those customers’ therapeutic product candidates, and it may be necessary for us to do so in order to successfully compete for the business of
these customers. If we do not successfully develop FDA-approved companion diagnostics, we may be at a competitive disadvantage and may be unable to
increase market acceptance and sales of our other product offerings, which would prevent us from increasing or sustaining our revenues or achieving or
sustaining  profitability.  If  we  were  to  develop  one  or  more  FDA-approved  companion  diagnostics,  we  would  incur  increased  research  and  development
expenses, and such activities may also divert our resources or the attention of our management and may create competing internal priorities for us.

Additionally,  projects  related  to  cancer  diagnostics  and  particularly  genomics  have  received  increased  government  funding,  both  in  the  United
States of America (the “U.S.”) and internationally. As more information regarding cancer genomics becomes available to the public, we anticipate that more
products  and  services  aimed  at  identifying  treatment  options  will  be  developed  and  that  these  products  and  services  may  compete  with  our  services.  In
addition, competitors may develop their own versions of our current or planned future services in countries where we did not apply for or receive patents and
compete with us in those countries, including encouraging the use of their products or services by biopharmaceutical companies in other countries.

We have substantial customer concentration, with a limited number of customers accounting for a substantial portion of our revenues
and accounts receivable.

Like other genomic profiling companies that sell to the pharmaceutical industry, we have substantial customer concentration. We currently derive a
significant  portion  of  our  revenues  from  the  U.S.  Department  of  Veterans  Affairs  (the  “VA”)  Million  Veteran  Program  (the  “VA  MVP”),  which  accounted  for
71%, 67%, and 49% of our revenues for the years ended December 31, 2020, 2019, and 2018, respectively. Our top five customers, including the VA MVP,
accounted for 87%, 90, and 82% of our revenues for the years ended December 31, 2020, 2019, and 2018, respectively. There are inherent risks whenever
a large percentage of revenues are concentrated with a limited number of customers. Our predictions regarding the future level of demand for our services
that will be generated by these customers may be wrong. In addition, revenues from our larger customers have historically fluctuated and may continue to
fluctuate based on the commencement and completion of clinical trials or other projects, the timing of which may be affected by market conditions or other
factors,  some  of  which  may  be  outside  of  our control.  Further,  while  we  have  long-term  contractual  arrangements  with  certain  of  our  customers,  these
customers are not required to purchase a minimum number of analyses. Some of our customers have in the past suspended or terminated clinical trials or
projects, received less funding than expected, experienced declining or delayed sales, or otherwise decided to reduce or eliminate their use of our services,
and these and other customers may also do so in the future. As a result, we could be pressured to reduce the prices we charge for our services, which would
have an adverse effect on our margins and financial position, and which would likely negatively affect our revenues and results of operations. In particular, if
the VA MVP terminates our services for convenience, which it is permitted to do, such termination would have a material adverse effect on our revenues,
cash position, and results of operations. Similarly, if the VA MVP was eliminated, awarded its contract to one of our competitors, further reduced the size of
our contract or failed to renew our contract in the future, then our revenues, cash position, and results of operations would be materially adversely impacted.
Further,  if  any  of  our  other  significant  customers  were  to  cease  using  or  stop  payment  for  our  services,  it  would  have  a  material  adverse  effect  on  our
accounts receivable, increasing our credit

25

risk. The failure of these customers to pay their balances, or any customer to pay future outstanding balances, would result in an operating expense and
reduce our cash flows.

We  currently  derive  a  substantial  portion  of  our  revenues  from  DNA  sequencing  and  data  analysis  services  that  we  provide  to  our
largest  customer,  the  VA  MVP.  If  the  VA  MVP’s  demand  for  and/or  funding  for  our  DNA  sequencing  and  data  analysis  services  is
substantially  reduced  or  if  the  VA  MVP  conducts  a  competitive  bid  process  for  the  next  contract  and  we  do  not  win,  our  business,
financial condition, operating results, and cash flows would be materially harmed.

We derive a substantial portion of our current and expected future revenues from sales of our DNA sequencing and data analysis services to the
VA MVP. In September 2017, we entered into a one-year contract with three one-year option renewal periods with the VA for the VA MVP, pursuant to which
we received contracted orders from the VA MVP in September 2017, 2018, 2019, and 2020. This contract expired in August 2021 and does not include a
renewal option. Our current task order under this contract extends through August 2021. In order for us to provide additional services to the VA MVP after
August  2021,  we  would  need  to  receive  an  additional  task  order  before  the  current  contract  expires  in  September  2021,  or  enter  into  a  new  services
agreement with the VA MVP.

The VA MVP may initiate a competitive bidding process for its next DNA sequencing and data analysis services contract. We may not win any
potential  new  contract  in  such  bidding  process,  the  value  of  such  contract  or  the  VA  MVP  contracted  orders  thereunder  may  be  lower  than  our  current
contract and historical contracted orders from the VA MVP, and/or the scope or nature of the services required under such new contract may change such
that we are unable to serve the VA MVP in the future.

The  VA  MVP’s  contracted  orders  for  DNA  sequencing  and  data  analysis  services  have  fluctuated  in  value  over  time  and  are  subject  to  the
availability of funding, enrollment of veterans in the VA MVP study, and the VA MVP’s continued demand for our services among other factors. For example,
the VA MVP contracted order received in September 2020 has a value of up to approximately $31 million, whereas the VA MVP contracted order received in
September 2019 had a value of up to approximately $38.1 million. We have no certainty that funding will be made available for our services, or that the VA
MVP will award any future contracts, contract renewals or contracted orders to us. If the priorities of the VA, the VA MVP, or the U.S. government change,
including in response to the COVID-19 pandemic for example, funding for our services may be limited or not available, and our business, financial condition,
and operating results and cash flows would be materially harmed. Similarly, if we do not win future VA MVP contracts and renewals (whether due to being
outbid by a competitor or the VA MVP’s decision to terminate for convenience or failure to renew for whatever reason), our business, financial condition, and
operating results and cash flows would be materially harmed. The success of our business and our future operating results are significantly dependent on
the VA MVP’s receipt of funding for use of our services and the terms of our sales to the VA MVP, including the price per sample, the number of samples and
the timing of the VA MVP’s deliveries of samples. Furthermore, we only recognize revenue under our VA MVP contract upon the receipt and processing of
samples, and the timing and number of VA MVP samples we receive has been and could in the future be negatively affected by factors beyond our control,
which has resulted, and may result in the future, in delaying our ability to process and recognize revenue for such samples. For example, the revenue we
recognized  during  the  contract  year  that  began  in  September  2019  significantly  exceeded  the  value  of  the  VA  MVP  contracted  order  we  received  in
September 2019 because we continued to receive after such date, and subsequently processed, samples under VA MVP contracted orders that remained
unfulfilled as of September 2019 due to the time required for the VA to select optimal samples from its collection for research and then provide us those
samples. Therefore, period-to-period comparisons of our operating results relating to VA MVP contracted orders may not be meaningful and, even if we win
a potential new VA MVP contract and order with a value comparable to that of the September 2019 contracted order, the revenue we recognize under such
potential new contract and order may be less than the revenue we recognized during the 2019-2020 contract year, and may also be less than the revenue
we  expect  to  recognize  during  the  2020-2021  contract  year  because  we  expect  during  the  current  contract  year  to  finish  processing  most  or  all  of  the
samples  under  VA  MVP  contracted  orders  that  remained  unfulfilled  as  of  September  2020,  in  addition  to  samples  received  under  the  September  2020
contracted  order.  The  timing  and  number  of  VA  MVP  samples  may  also  have  been  or  be  negatively  affected  by  the  current  COVID-19  pandemic.  For
example,  in  March  2020,  the  VA  MVP  announced  that  it  was  suspending  sample  collection  due  to  the  COVID-19  pandemic.  In  addition,  we  believe  the
COVID-19  pandemic  may  have  been  a  contributing  factor  to  the  reduction  in  value  of  the  September  2020  VA  MVP  contracted  order  compared  to  the
September 2019 contracted order, as the VA MVP delayed new enrollment and also may have needed to divert resources to respond to the pandemic, and
the COVID-19 pandemic may also negatively impact the value of any potential new VA MVP contract or order.

If  we  cannot  maintain  our  current  customer  relationships,  or  fail  to  acquire  new  customers,  our  revenue  prospects  will  be  reduced.
Many of our customers are biopharmaceutical companies engaged in clinical trials of new drug candidates, which trials are expensive,
can take many years to complete, and have inherently uncertain outcomes.

Our  customers  other  than  the  VA  MVP  are  primarily  biopharmaceutical  companies  that  use  our  services  to  support  clinical  trials.  Our  future
success is substantially dependent on our ability to maintain our customer relationships and to establish new ones. Many factors have the potential to impact
our customer relations, including the type of support our customers and potential customers require and our ability to deliver it, our customers’ satisfaction
with  our  services,  and  other  factors  that  may  be  beyond  our  control.  Furthermore,  our  customers  may  decide  to  decrease  or  discontinue  their  use  of  our
services due to changes in research and product development plans (including as a result of the COVID-19 pandemic), failures in their clinical trials, financial
constraints, or utilization of internal testing resources or tests performed by other parties, or other circumstances outside of our control.

26

We  engage  in  conversations  with  customers  regarding  potential  commercial  opportunities  on  an  ongoing  basis  in  the  event  that  one  of  these
customers’ drug candidates is approved. There is no assurance that any of these conversations will result in a commercial agreement, or if an agreement is
reached,  that  the  resulting  relationship  will  be  successful  or  that  clinical  studies  conducted  as  part  of  the  engagement  will  produce  successful  outcomes.
Speculation in the industry about our existing or potential relationships with biopharmaceutical companies could be a catalyst for adverse speculation about
us, our services, and our technology, which can adversely affect our reputation and our business. In addition, the termination of these relationships could
result in a temporary or permanent loss of revenue.

Our customers’ clinical trials are expensive, can take many years to complete, and their outcome is inherently uncertain. Failure can occur at any
time during the clinical trial process. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having
progressed  through  pre-clinical  studies  and  early  clinical  trials.  Many  of  the  biopharmaceutical  companies  that  are  our  customers  do  not  have  products
approved for commercial sale and are not profitable. These customers must continue to raise capital in order to continue their development programs and to
potentially  continue  as  our  customers.  If  our  customers’  clinical  trials  fail  or  they  are  unable  to  raise  sufficient  capital  to  continue  investing  in  their  clinical
programs, our revenues from these customers may decrease or cease entirely, and our business may be harmed. Furthermore, even if these customers
have a drug approved for commercial sale, they may not choose to use our services as a companion diagnostic with their drug, thereby limiting our potential
revenues.

We rely on a limited number of suppliers, or in some cases, a sole supplier, for some of our laboratory instruments and materials, and
we may not be able to find replacements or immediately transition to alternative suppliers should we need to do so.

We rely on a limited number of suppliers for sequencers and other equipment and materials that we use in our laboratory operations. For example,
we rely on Illumina as the sole supplier of sequencers and various associated reagents, and as the sole provider of maintenance and repair services for
these sequencers. Our master subcontractor agreement with Illumina is set to expire in August 2021, and our various pricing agreements with Illumina are
set  to  expire  on  various  dates  up  to  December  2022.  In  September  2020,  Illumina  announced  it  had  entered  into  an  agreement  to  acquire  GRAIL,  a
company focused on early cancer detection and potentially other forms of cancer analysis using next-generation sequencing technology. Any disruption in
Illumina’s operations, or our inability to negotiate an extension to our agreements with Illumina on acceptable terms, or at all, or any competitive pressure
resulting from Illumina’s anticipated acquisition of GRAIL, could negatively impact our supply chain and laboratory operations and our ability to conduct our
business  and  generate  revenue.  Our  suppliers  could  cease  supplying  these  materials,  reagents,  and  equipment  at  any  time,  or  fail  to  provide  us  with
sufficient quantities of materials or materials that meet our specifications. Our laboratory operations could be interrupted if we encounter delays or difficulties
in securing equipment, materials, reagents, or sequencers, or if we cannot obtain an acceptable substitute. Any such interruption could significantly affect
our business, financial condition, results of operations, and reputation.

We  believe  that  there  are  only  a  few  manufacturers  other  than  Illumina  that  are  currently  capable  of  supplying  and  servicing  the  equipment
necessary  for  our  laboratory  operations,  including  sequencers  and  various  associated  reagents.  The  use  of  equipment  or  materials  provided  by  these
replacement suppliers would require us to alter our laboratory operations. Transitioning to a new supplier would be time-consuming and expensive, would
likely result in interruptions in our laboratory operations, could affect the performance specifications of our laboratory operations, or could require that we
revalidate  our  tests.  We  cannot  assure  you  that,  if  we  were  forced  to  replace  Illumina  or  another  supplier  on  which  we  rely,  we  would  be  able  to  secure
alternative equipment, reagents, and other materials, and bring such equipment, reagents, and materials on line and revalidate them without experiencing
interruptions in our workflow. If we encounter delays or difficulties in securing, reconfiguring, or revalidating the equipment and reagents we require for our
services, our business, financial condition, results of operations, and reputation could be adversely affected.

In addition, the Device Master File that we have filed with the FDA, which is focused on the technology, quality management, and validation of our
platform,  specifically  on  its  use  for  the  development  of  personalized  immunotherapies,  is  predicated  on  our  use  of  specified  equipment  and  processes,
including  Illumina  sequencers  and  related  equipment.  The  detailed  information  in  the  Device  Master  File  is  not  shared  with  our  customers,  but  with  our
permission they can reference our FDA file number in their Investigational New Drug filings with the FDA. If we were required to transition to a new supplier
of sequencers or certain other equipment or processes in our laboratory, our Device Master File would need to be replaced or updated, and until such time
as that occurred, customers for which we deliver services after the transition would not be able to reference our Device Master File, which would cause us to
lose a competitive advantage.

27

We  will  need  to  invest  in  our  infrastructure  in  advance  of  increased  demand  for  our  services,  and  our  failure  to  accurately  forecast
demand would have a negative impact on our business and our ability to achieve and sustain profitability.

In  order  to  execute  our  business  model,  we  need  to  invest  in  scaling  our  infrastructure,  including  hiring  additional  personnel  and  expanding
laboratory capacity. We will also need to purchase additional equipment, some of which can take several months or more to procure, setup, and validate,
and  increase  our  software  and  computing  capacity  to  meet  increased  demand.  There  is  no  assurance  that  any  of  these  increases  in  scale,  expansion  of
personnel, equipment, software, and computing capacities, or process enhancements will be successfully implemented, or that we will have adequate space
in our laboratory facilities to accommodate such required expansion. We expect that much of this growth will be in advance of increased demand for our
services. Our current and projected future expense levels are to a large extent fixed and are largely based on our current investment plans and our estimates
of  future  test  volume.  As  a  result,  if  revenues  do  not  meet  our  expectations  we  may  not  be  able  to  promptly  adjust  or  reduce  our  spending  to  levels
commensurate  with  our  revenues.  If  we  fail  to  generate  demand  commensurate  with  our  infrastructure  growth  or  if  we  fail  to  scale  our  infrastructure
sufficiently  in  advance  of  demand  to  successfully  meet  such  demand,  our  business,  prospects,  financial  condition,  and  results  of  operations  could  be
adversely affected.

As  we  commercialize  additional  services  or  products,  we  may  need  to  incorporate  new  equipment,  implement  new  technology  systems  and
laboratory processes, or hire new personnel with different qualifications. Failure to manage this growth or transition could result in turnaround time delays,
higher costs, declining service and/or product quality, deteriorating customer service, and slower responses to competitive challenges. A failure in any one of
these areas could make it difficult for us to meet market expectations for our services, and could damage our reputation and the prospects for our business.

If our facilities become damaged or inoperable, or we are required to vacate the facilities, our ability to sell and provide our services and
pursue our research and development efforts may be jeopardized.

We currently derive our revenues from our genomic analysis conducted in our laboratories. We do not have any clinical reference or research and
development laboratory facilities other than our facilities in Menlo Park, California, and the facilities being developed for our use in Shanghai, China. Our
facilities  and  equipment  could  be  harmed  or  rendered  inoperable  by  natural  or  man-made  disasters,  including  fires,  earthquakes,  flooding,  and  power
outages,  which  may  render  it  difficult  or  impossible  for  us  to  sell  or  perform  our  services  for  some  period  of  time.  Additionally,  as  a  result  of  the  ongoing
COVID-19 pandemic, we have limited access to our office and laboratory facilities in Menlo Park to protect the health and safety of our employees and to
comply with applicable state and local orders. Northern California has recently experienced serious fires and the San Francisco Bay Area is considered to lie
in  an  area  with  earthquake  risk.  The  inability  to  sell  or  to  perform  our  sequencing  and  analysis  services,  disruptions  in  our  operations,  or  the  backlog  of
samples that could develop if our facilities are inoperable for even a short period of time, may result in the loss of customers or harm to our reputation or
relationships with scientific or clinical collaborators, and we may be unable to regain those customers or repair our reputation or such relationships in the
future. The limited access to our laboratory facilities as a result of the COVID-19 pandemic has resulted, and may in the future result, in a loss in productivity,
including delays to research and development programs. Furthermore, our facilities and the equipment we use to perform our services and our research and
development work could be costly and time-consuming to repair or replace.

Additionally, a key component of our research and development process involves using biological samples as the basis for the development of our
services. In some cases, these samples are difficult to obtain. If the parts of our laboratory facilities where we store these biological samples were damaged
or  compromised,  our  ability  to  pursue  our  research  and  development  projects,  as  well  as  our  reputation,  could  be  jeopardized.  We  carry  insurance  for
damage to our property and the disruption of our business, but this insurance may not be sufficient to cover all of our potential losses and may not continue
to be available to us on acceptable terms, if at all.

Further, if our laboratory facilities became inoperable, we would likely not be able to license or transfer our technology to other facilities with the
qualifications, including state licensure and CLIA certification, that would be necessary to cover the scope of our current and our planned future services.
Even if we were to find facilities with such qualifications to perform our services, they may not be available to us on commercially reasonable terms.

Our  success  depends  on  our  ability  to  provide  reliable,  high-quality  genomic  data  and  analyses  and  to  rapidly  evolve  to  meet  our
customers’ needs.

Errors,  including  if  our  tests  fail  to  accurately  detect  gene  variants,  or  mistakes,  including  if  we  fail  to  or  incompletely  or  incorrectly  identify  the
significance of gene variants, could have a significant adverse impact on our business. We classify variants in accordance with guidelines that are subject to
change and subject to our interpretation. There have also been and could in the future be flaws in the databases, third-party tools or algorithms we use, or in
the  software  that  handles  automated  parts  of  our  classification  protocol.  If  we  receive  poor  quality  or  degraded  samples,  our  tests  may  be  unable  to
accurately  detect  gene  variants  or  we  may  fail  to  or  incompletely  or  incorrectly  identify  the  significance  of  gene  variants,  which  could  have  a  significant
adverse impact on our business.

Inaccurate  results  or  misunderstandings  of,  or  inappropriate  reliance  on,  the  information  we  provide  to  our  customers  could  lead  to,  or  be
associated with, side effects or adverse events in patients who use our tests, including treatment-related death, and could lead to termination of our services
or claims against us. A product liability or professional liability claim could result in substantial damages and be costly and time-consuming for us to defend.

28

Although  we  maintain  liability  insurance,  including  for  errors  and  omissions  and  professional  liability,  we  cannot  assure  you  that  our  insurance
would be sufficient to protect us from the financial impact of defending against these types of claims, or any judgments, fines, or settlement costs arising out
of any such claims. Any liability claim, including an errors and omissions liability claim, brought against us, with or without merit, could increase our insurance
rates  or  prevent  us  from  securing  insurance  coverage  in  the  future.  Additionally,  any  liability  lawsuit  could  cause  injury  to  our  reputation  or  cause  us  to
suspend sales of our tests or cause a suspension of our license to operate. The occurrence of any of these events could have an adverse effect on our
business, reputation, and results of operations.

If we cannot develop services and products to keep pace with rapid advances in technology, medicine, and science, or if we experience
delays in developing such services and products, our operating results and competitive position could be harmed.

In recent years, there have been numerous advances in technologies relating to the diagnosis and treatment of cancer. Several new cancer drugs
have been approved, and a number of new drugs are in pre-clinical and clinical development. There have also been advances in methods used to identify
patients likely to benefit from these drugs based on analysis of biomarkers. We must continuously develop new services and products, enhance any existing
services,  and  avoid  delays  in  such  developments  and  enhancements  to  keep  pace  with  evolving  technologies  on  a  timely  and  cost-effective  basis.  Our
current  services  and  our  planned  future  services  and  products  could  become  obsolete  unless  we  continually  innovate  and  expand  them  to  demonstrate
benefit in the diagnosis, monitoring, or prognosis of patients with cancer. New cancer therapies typically have only a few years of clinical data associated
with  them,  and  much  of  that  data  may  not  be  disclosed  by  the  pharmaceutical  company  that  conducted  the  clinical  trials.  This  could  limit  our  ability  to
develop services and products based on, for example, biomarker analysis related to the appearance or development of resistance to those therapies. If we
cannot adequately demonstrate the clinical utility of our services and our planned future services and products to new treatments, sales of our services could
decline, which would have a material adverse effect on our business, financial condition, and results of operations.

We are researching and developing improvements to our tests and test features on a continuous basis, but we may not be able to make
these improvements on a timely basis, and even if we do, we may not realize the benefits of these efforts in our financial results.

To remain competitive, we must continually research and develop improvements to our tests or test features. However, we cannot assure you that
we  will  be  able  to  develop  and  commercialize  the  improvements  to  our  tests  or  test  features  on  a  timely  basis.  Our  competitors  may  develop  and
commercialize competing or alternative tests and improvements faster than we are able to do so. In addition, we must expend significant time and funds in
order to conduct research and development, further develop and scale our laboratory processes, and further develop and scale our infrastructure. We may
never realize a return on investment on this effort and expense, especially if our improvements fail to perform as expected. If we are not able to realize the
benefits of our efforts to improve our tests or test features, it could have an adverse effect on our business, financial condition, and results of operations.

Personalized  cancer  therapies  represent  new  therapeutic  approaches  that  could  result  in  heightened  regulatory  scrutiny,  delays  in
clinical development, or delays in or inability to achieve regulatory approval, commercialization, or payor coverage, any of which could
adversely affect our business.

We  currently  work  with  certain  companies  developing  personalized  cancer  therapies,  and  our  future  success  will  in  part  depend  on  our
personalized  cancer  customers  obtaining  regulatory  approval  for  and  commercializing  their  product  candidates.  Because  personalized  cancer  therapies
represent a new approach to immunotherapy for the treatment of cancer and other diseases, developing and commercializing personalized cancer therapies
is subject to a number of challenges.

Actual  or  perceived  safety  issues,  including  adoption  of  new  therapeutics  or  novel  approaches  to  treatment,  may  adversely  influence  the
willingness of subjects to participate in clinical studies, or if approved by applicable regulatory authorities, of physicians to subscribe to the novel treatment
mechanics. The FDA or other applicable regulatory authorities may ask for specific post-market requirements, and additional information regarding benefits
or risks of our services may emerge at any time prior to or after regulatory approval.

In  the  EEA  (and  Northern  Ireland)  the  new  European  Union  (“EU”)  In  Vitro  Diagnostic  Device  Regulation  (the  “IVDR”)  entered  into  force  on
May 25, 2017, replacing the In-Vitro Diagnostic Directive (the “IVDD”) (and national legislation that implemented the IVDD in member states) as the primary
legislation  governing  in-vitro  diagnostic  devices  (“IVD”).  Most  requirements  under  the  IVDR  will  not  apply  until  the  end  of  a  transition  period  which  is
expected to occur on May 26, 2022. The IVDR broadens the scope of the regulation of IVDs and, amongst other things, tightens the requirements for clinical
evidence and conformity assessment, increases transparency requirements, and introduces a requirement for a unique device identifier for every IVD. Under
the IVDR there are four classes of IVDs, referred to as classes A, B, C, and D. IVDs are placed into a class based on their perceived risk to the patient and
wider  public.  The  main  requirements  of  the  IVDR  apply  regardless  of  the  class  which  the  relevant  device  falls  into,  and  class  A  devices  (including
instruments and specimen receptacles) are the only devices that can be self-certified as meeting the requirements of the IVDR. The IVDR explicitly includes
software used for diagnostic purposes in its scope. The IVDR requires pre-registration and post-market data collection to ensure that the device meets the
relevant requirements. It is also notable that diagnostic and therapeutic services offered to customers in the EEA (and Northern Ireland) (whether directly or
via intermediaries) by providers that are based outside the EEA will be covered by the IVDR. The IVDR will not apply to Great Britain (England, Wales and
Scotland). These additional regulatory requirements are likely to increase the cost and time required in order to obtain regulatory approval for products in the
EEA where such approval was already necessary, and in certain cases will introduce a new requirement to obtain regulatory approval where one did not

29

exist under the IVDD arrangements. Further, the IVDR may result in devices being classified in a higher risk category than would have been the case under
the existing IVDD arrangements.

Physicians, hospitals, and third-party payors often are slow to adopt new products, technologies, and treatment practices that require additional
upfront costs and training. Physicians may not be willing to undergo training to adopt personalized cancer therapies, may decide that such therapies are too
complex  to  adopt  without  appropriate  training  or  not  cost-efficient,  and  may  choose  not  to  administer  these  therapies.  Based  on  these  and  other  factors,
hospitals and payors may decide that the benefits of personalized cancer therapies do not or will not outweigh their costs.

The loss of key members of our executive management team could adversely affect our business.

Our success in implementing our business strategy depends largely on the skills, experience, and performance of key members of our executive
management team and others in key management positions, including John West, our Chief Executive Officer, Richard Chen, our Chief Scientific Officer,
and Aaron Tachibana, our Chief Financial Officer. The collective efforts of each of these persons and others working with them as a team are critical to us as
we continue to develop our technologies, services, products, and research and development programs. As a result of the difficulty in locating qualified new
management, the loss or incapacity of existing members of our executive management team could adversely affect our operations. If we were to lose one or
more of these key employees, or if one or more of these key employees were to become unable to perform his or her duties due to contracting COVID-19,
we could experience difficulties in finding qualified successors, competing effectively, developing our technologies, and implementing our business strategy.
Each member of our executive management team has an employment agreement; however, the existence of an employment agreement does not guarantee
retention of members of our executive management team, and we may not be able to retain those individuals. We do not maintain “key person” life insurance
on any of our employees.

In addition, we rely on collaborators, consultants, and advisors, including scientific and clinical advisors, to assist us in formulating our research
and development and commercialization strategy. Our collaborators, consultants, and advisors are generally employed by employers other than us and may
have commitments under agreements with other entities that may limit their availability to us.

The loss or extended illness of a key employee, the failure of a key employee to perform in his or her current position, or our inability to attract and

retain skilled employees could result in our inability to continue to grow our business or to implement our business strategy.

We rely on highly skilled personnel in a broad array of disciplines and if we are unable to hire, retain, or motivate these individuals, or
maintain our corporate culture, we may not be able to maintain the quality of our services or grow effectively.

Our  performance,  including  our  research  and  development  programs  and  laboratory  operations,  largely  depends  on  our  continuing  ability  to
identify, hire, develop, motivate, and retain highly skilled personnel for all areas of our organization. Competition in our industry for qualified employees is
intense,  and  we  may  not  be  able  to  attract  or  retain  qualified  personnel  in  the  future,  including  bioinformatic  scientists,  bioinformatic  engineers,  software
engineers,  statisticians,  variant  curators,  clinical  laboratory  scientists,  and  genetic  counselors,  due  to  the  competition  for  qualified  personnel  among  life
science businesses, technology companies, as well as universities and public and private research institutions, particularly in the San Francisco Bay Area.
All  of  our  U.S.  employees  are  at-will,  which  means  that  either  we  or  the  employee  may  terminate  their  employment  at  any  time.  In  addition,  our
compensation arrangements, such as our equity award programs, may not always be successful in attracting new employees and retaining and motivating
our  existing  employees  for  reasons  that  may  include  movements  in  our  stock  price.  If  we  are  not  able  to  attract  and  retain  the  necessary  personnel  to
accomplish our business objectives, we may experience constraints that could adversely affect our ability to scale our business and support our research
and development efforts and our laboratory operations. We believe that our corporate culture fosters innovation, creativity, and teamwork. However, as our
organization grows, we may find it increasingly difficult to maintain the beneficial aspects of our corporate culture. This could negatively impact our ability to
retain and attract employees and our future success.

We may not be able to manage our future growth effectively, which could make it difficult to execute our business strategy.

Our expected future growth could create a strain on our organizational, administrative, and operational infrastructure, including facilities, laboratory
operations, quality control, customer service, marketing and sales, and management. We may not be able to maintain the quality of or expected turnaround
times for our tests, or satisfy customer demand as our test volume grows. Our ability to manage our growth properly will require us to continue to improve
our operational, financial, and management controls, as well as our reporting systems and procedures. As a result of our growth, our operating costs may
escalate  even  faster  than  planned,  and  some  of  our  internal  systems  may  need  to  be  enhanced  or  replaced.  If  we  are  unable  to  manage  our  growth
effectively, it may be difficult for us to execute our business strategy and our business could be harmed.

30

We may acquire businesses or assets, form joint ventures, or make investments in other companies or technologies that could harm
our operating results, dilute our stockholders’ ownership, or cause us to incur debt or significant expense.

As  part  of  our  business  strategy,  we  may  pursue  acquisitions  of  complementary  businesses  or  assets,  as  well  as  technology  licensing
arrangements. We may also pursue strategic alliances that leverage our core technology and industry experience to expand our offerings or distribution, or
make  investments  in  other  companies.  As  an  organization,  we  have  limited  experience  with  respect  to  acquisitions  as  well  as  the  formation  of  strategic
alliances  and  joint  ventures.  We  may  not  identify  or  complete  these  transactions  in  a  timely  manner,  on  a  cost-effective  basis,  or  at  all,  and  we  may  not
realize  the  anticipated  benefits  of  any  acquisition,  technology  license,  strategic  alliance,  joint  venture  or  investment,  and  their  consideration  may  be
distracting  to  our  management  or  prevent  us  from  pursuing  other  opportunities.  In  addition,  we  may  not  be  able  to  find  suitable  partners  or  acquisition
candidates,  and  we  may  not  be  able  to  complete  such  transactions  on  favorable  terms,  if  at  all.  Any  future  such  transactions  by  us  also  could  result  in
significant write-offs, the incurrence of debt and contingent liabilities, exposure to additional liability, exposure to additional revenue concentration, additional
regulatory  obligations  and  exposure  to  additional  potential  liability,  any  of  which  could  harm  our  operating  results  and  future  prospects.  If  we  make  any
acquisitions  in  the  future,  we  may  not  be  able  to  integrate  these  acquisitions  successfully  into  our  existing  business,  and  we  could  assume  unknown  or
contingent liabilities. Integration of an acquired company or business also may require management resources that otherwise would be available for ongoing
development of our existing business.

To  finance  any  acquisitions  or  investments,  we  may  choose  to  raise  additional  funds.  The  various  ways  we  could  raise  additional  funds  carry
potential risks. See “Financial and Market Risks and Risks Related to Owning Our Common Stock—Our inability to raise additional capital on acceptable
terms in the future may limit our ability to continue to operate our business and further expand our operations.” If the price of our common stock is low or
volatile, we may not be able to acquire other companies using stock as consideration. Alternatively, it may be necessary for us to raise additional funds for
these activities through public or private financings. Additional funds may not be available on terms that are favorable to us, or at all.

Ethical, legal, and social concerns related to the use of genetic information could reduce demand for our tests.

Genetic  testing  has  raised  ethical,  legal,  and  social  concerns  regarding  privacy  and  the  appropriate  uses  of  the  resulting  information.
Governmental authorities have, through the Genetic Information Nondisclosure Act, and could further, for social or other purposes, limit or regulate the use of
genetic information or genetic testing or prohibit testing for genetic predisposition to certain conditions, particularly for those that have no known cure. Ethical
and social concerns may also influence governmental authorities to deny or delay the issuance of patents for technology relevant to our business. Similarly,
these concerns may lead patients to refuse to use, or clinicians to be reluctant to order, genetic tests even if permissible. These and other ethical, legal, and
social concerns may limit market acceptance of our tests or reduce the potential markets for our tests, either of which could have an adverse effect on our
business, financial condition, or results of operations.

Any collaboration arrangements that we have entered into or may enter into in the future may not be successful, which could adversely
affect our ability to develop and commercialize our services and products.

Any current or future collaborations, including any strategic alliances or any collaborations to develop companion diagnostic tests, that we have
entered  or  may  enter  into  may  not  be  successful.  The  success  of  our  collaboration  arrangements  will  depend  heavily  on  the  efforts  and  activities  of  our
collaborators. Collaborations are subject to numerous risks, which include that:

•

•

•

•

•

•

•

we  may  incur  increased  research  and  development  expenses,  and  such  activities  may  also  divert  management  attention  and  resources
and/or  create  competing  internal  priorities  for  us,  which  could  prevent  us  from  successfully  conducting  other  parts  of  our  business  or
collaborating with others;

collaborators have significant discretion in determining the efforts and resources that they will apply to collaborations;

collaborators  may  not  pursue  development  and  commercialization  of  our  services  or  products  or  may  elect  not  to  continue  or  renew
development  or  commercialization  programs  based  on  trial  or  test  results,  changes  in  their  strategic  focus  due  to  the  acquisition  of
competitive services or products, availability of funding, or other external factors, such as a business combination that diverts resources or
creates competing priorities for our collaborator;

collaborators  could  independently  develop,  or  develop  with  third  parties,  services  or  products  that  compete  directly  or  indirectly  with  our
services or products;

to or otherwise not perform satisfactorily in carrying out these activities;

we could grant exclusive rights to our collaborators that would prevent us from collaborating with others;

adverse events in patients, exposing us to potential liability or regulatory review; and

collaborators’ sales and marketing activities or other operations may not be in compliance with applicable laws resulting in civil or criminal
proceedings.

If we are unable to successfully obtain rights to required third-party intellectual property rights or maintain the existing intellectual property rights

we have, we may have to abandon development of that program and our business and financial condition could suffer.

Our planned expansion into China entails substantial risks.

In June 2020, we announced a partnership with a clinical genomics and life sciences company headquartered in China as a means to expand
business operations into China in the near term. Our first wholly owned subsidiary was formed in Shanghai in October 2020. Our expansion and investment
plans are subject to substantial risks which may include, but are not limited to: the inability to protect our intellectual property rights under Chinese law, which
may not offer as high a level of protection as U.S. law; unexpectedly long negotiation periods with Chinese suppliers and customers; quality issues related to
supplies sourced from local vendors; unexpectedly high labor costs due to a tight labor supply; foreign investment restrictions; and difficulty in repatriating
funds and selling or transferring assets. Our investments in China also expose us to additional foreign currency exchange risk. In addition, as tensions have
escalated between the U.S. and China, we believe there is an enhanced risk that our planned investments in China may be subject to unforeseen risks or
restrictions, which may include expropriation of the investments by the Chinese government. These and other risks may result in our not realizing a return
on,  or  losing  some,  or  all,  of  our  planned  investments  in  China,  which  could  have  a  material  adverse  effect  on  our  financial  condition  and  financial
performance.

Personal privacy, cyber security, and data protection are becoming increasingly significant issues in China. For example, the State Council of the
People’s  Republic  of  China  adopted  the  Regulations  of  the  People’s  Republic  of  China  on  Administration  of  Human  Genetic  Resources,  which  went  into
effect on July 1, 2019. The regulations establish a framework for the collection, preservation, utilization, and supply abroad of human genetic resources of
China. The regulations also establish a framework for the use of data and other information generated from use of human genetic resources of China. The
regulations  also  provide  that  foreign  organizations,  individuals  and  entities  established  or  controlled  by  them  are  prohibited  to  collect  or  preserve  China’s
human  genetic  resources  or  transport  them  abroad.  Due  to  the  lack  of  detailed  interpretations  and  implementations,  it  is  not  clear  whether  the  agency  in
China responsible for enforcing the regulations will grant the necessary approvals for use by us and our partners of our NeXT Platform or our other current or
future  products  in  research  or  clinical  projects  involving  China’s  human  genetic  resources  or  information  generated  therefrom.  The  Chinese  government
separately has various regulations relating to the collection, use, storage, disclosure, and security of data, among other things. We cannot assure you that
we will be able to comply with all of these regulatory requirements. Any failure to comply with relevant regulations and policies could result in significant cost
and  liability  to  us  and  could  adversely  affect  our  business  and  results  of  operations.  Any  additional  new  regulations  or  the  amendment  or  modification  of
previously implemented regulations, or the failure to receive any necessary approvals for use of our products in connection with such projects, could require
us and our partners to change our business plans and incur additional costs, and could limit our ability to generate revenues in China.

Expansion into international markets would subject us to increased regulatory oversight and regulatory, economic, social, health and
political uncertainties, which could cause a material adverse effect on our business, financial position, and results of operations.

We may in the future expand our business and operations into international jurisdictions in which we have limited operating experience, including
with respect to seeking regulatory approvals and marketing and selling products and services. For example, in June 2020, we announced our intention to
expand  into  China.  As  we  expand  internationally,  our  operations  in  these  jurisdictions  may  be  adversely  affected  by  general  economic  conditions  and
economic and fiscal policy, including changes in exchange rates and controls, interest rates and taxation policies, increased government regulation, social
instability,  local  or  regional  health  crises,  and  political,  economic  or  diplomatic  developments  in  the  future.  Certain  jurisdictions  have,  from  time  to  time,
experienced  instances  of  civil  unrest  and  hostilities,  both  internally  and  with  neighboring  countries.  Rioting,  military  activity,  terrorist  attacks,  or  armed
hostilities could cause our operations in such jurisdictions to be adversely affected or suspended. We generally do not have insurance for losses and

32

 
 
 
 
 
 
interruptions caused by terrorist attacks, military conflicts and wars. In addition, anti-bribery and anti-corruption laws may conflict with some local customs
and practices in foreign jurisdictions. Our international operations may subject us to heightened scrutiny under the FCPA, the United Kingdom (the “U.K.”)
Bribery Act and similar anti-bribery laws, and could subject us to liability under such laws despite our best efforts to comply with such laws. As a result of our
policy  to  comply  with  the  FCPA,  the  U.K.  Bribery  Act  and  similar  anti-bribery  laws,  we  may  be  at  a  competitive  disadvantage  to  competitors  that  are  not
subject to, or do not comply with, such laws. Further, notwithstanding our compliance programs, there can be no assurances that our policies will prevent our
employees  or  agents  from  violating  these  laws  or  protect  us  from  any  such  violations.  Additionally,  we  cannot  predict  the  nature,  scope  or  impact  of  any
future  regulatory  requirements  that  may  apply  to  our  international  operations  or  how  foreign  governments  will  interpret  existing  or  new  laws.  Alleged,
perceived, or actual violations of any such existing or future laws by us or due to the acts of others, may result in criminal or civil sanctions, including contract
cancellations or debarment, and damage to our reputation, any of which could have a material adverse effect on our business.

Regulatory, Legal and Cybersecurity Risks

Our tests may be subject to regulatory action if regulatory agencies determine that our tests do not appropriately comply with statutory
and  regulatory  requirements  enforced  by  the  U.S.  Food  and  Drug  Administration,  and/or  CLIA  requirements  for  quality  laboratory
testing.

The laws and regulations governing the marketing of clinical laboratory tests are extremely complex and in many instances there are no significant
regulatory or judicial interpretations of these laws and regulations. The Federal Food, Drug and Cosmetic Act (the “FDC Act”) defines a medical device to
include any instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent or other similar or related article, including a component, part,
or accessory, 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. Some of our tests may be considered by the FDA to be in vitro diagnostic products that are subject to regulation as medical devices. Among other
things,  pursuant  to  the  FDC  Act  and  its  implementing  regulations,  the  FDA  regulates  the  research,  testing,  manufacturing,  safety,  labeling,  storage,
recordkeeping, premarket clearance or approval, marketing and promotion, and sales and distribution of medical devices in the U.S. to ensure that medical
products distributed domestically are safe and effective for their intended uses. In addition, the FDA regulates the import and export of medical devices.

Although  the  FDA  has  statutory  authority  to  assure  that  medical  devices  are  safe  and  effective  for  their  intended  uses,  the  FDA  has  generally
exercised its enforcement discretion and not enforced applicable regulations with respect to laboratory developed tests (“LDTs”), which are a subset of in
vitro diagnostic devices that are intended for clinical use and designed, manufactured, and used entirely within a single laboratory. We currently market our
tests as LDTs and, therefore, we believe that they are not currently subject to the FDA’s enforcement of its medical device regulations and the applicable
FDC Act provisions. Despite the FDA’s historic enforcement discretion policy with respect to LDTs, in November 2017, the FDA finalized a classification order
setting  out  the  regulatory  requirements  that  apply  to  certain  genetic  health  risk  tests  and  revised  a  separate  classification  order  exempting  certain  carrier
screening  tests  from  FDA  premarket  clearance  and  approval  requirements  when  certain  regulatory  requirements  are  met.  None  of  our  tests  comply  with
these classification orders because we market our tests as LDTs that are subject to the FDA’s policy of enforcement discretion. However, the FDA may find
that  our  tests  do  not  fall  within  the  definition  of  an  LDT,  and  may  determine  that  our  tests  are  subject  to  the  FDA’s  enforcement  of  its  medical  device
regulations, including the recent classification orders, and the applicable FDC Act provisions. While we believe that we are currently in material compliance
with  applicable  laws  and  regulations,  we  cannot  assure  you  that  the  FDA  or  other  regulatory  agencies  would  agree  with  our  determination,  and  a
determination  that  we  have  violated  these  laws,  or  a  public  announcement  that  we  are  being  investigated  for  possible  violations  of  these  laws,  could
adversely  affect  our  business,  prospects,  results  of  operations  or  financial  condition.  If  the  FDA  determines  that  our  tests  are  subject  to  enforcement  as
medical  devices,  we  could  be  subject  to  enforcement  action,  including  administrative  and  judicial  sanctions,  and  additional  regulatory  controls  and
submissions for our tests, all of which could be burdensome. See “—Failure to comply with federal, state, and foreign laboratory licensing requirements and
the applicable requirements of the FDA or any other regulatory authority, could cause us to lose the ability to perform our tests, experience disruptions to our
business or become subject to administrative or judicial sanctions.”

Moreover, LDTs may in the future become subject to more onerous regulation by the FDA. A significant change in any of the laws, regulations, or
policies  may  require  us  to  change  our  business  model  in  order  to  maintain  regulatory  compliance.  At  various  times  since  2006,  the  FDA  has  issued
documents  outlining  its  intent  to  require  varying  levels  of  FDA  oversight  of  many  types  of  LDTs.  In  October  2014,  the  FDA  issued  two non-binding  draft
guidance documents that set forth a proposed risk-based regulatory framework that would apply varying levels of FDA oversight to LDTs. The FDA indicated
that it did not intend to implement its proposed framework until the draft guidance documents are finalized. The FDA was expected to finalize its proposal for
the  oversight  of  LDTs  before  the  end  of  2016,  but  in  November  2016,  the  FDA  announced  that  it  would  halt  finalizing  of  the  guidance  documents  and
continue to work with stakeholders, the incoming administration, and Congress on the approach to LDT regulation. This announcement was followed by the
issuance of an information discussion paper on January 13, 2017, in which the FDA outlined a substantially revised “possible approach” to the oversight of
LDTs. The discussion paper explicitly states that it is not a final version of the 2014 draft guidance and that it is not enforceable and does not represent the
FDA’s “formal position.” It is unclear at this time if or when the FDA will finalize its plans to end enforcement discretion for LDTs, and even then, whether the
new regulatory requirements are expected to be phased-in over time. However, the FDA may decide to regulate certain LDTs on a case-by-case basis at any
time, which could result in delay or additional expense in offering our tests and tests that we may develop in the future.

Legislative proposals addressing oversight of genetic testing and LDTs have been introduced in previous Congresses, and we expect that new
legislative proposals will be introduced from time to time in the future. We cannot provide any assurance that FDA regulation, including pre-market review,
will not be required in the future for our tests, whether through finalization of guidance issued by

33

the FDA, new enforcement policies adopted by the FDA or new legislation enacted by Congress. It is possible that legislation will be enacted into law or
guidance could be issued by the FDA that may result in increased regulatory burdens for us to continue to offer our tests or to develop and introduce new
tests. This legislative and regulatory uncertainty exposes us to the possibility of enforcement action or additional regulatory controls and submissions for our
tests, both of which could be burdensome. We cannot be certain that the FDA will not enact rules or guidance documents that could impact our ability to
purchase certain materials necessary for the performance of our tests, such as products labeled for research use only. Should any of the reagents obtained
by us from suppliers and used in conducting our tests be affected by future regulatory actions, our business could be adversely affected by those actions,
including increasing the cost of testing or delaying, limiting, or prohibiting the purchase of reagents necessary to perform testing.

Additionally, the Centers for Medicare & Medicaid Services (“CMS”), and certain state agencies regulate the performance of LDTs (as authorized
under CLIA and state law, respectively). Our tests are developed in compliance with CLIA requirements. However, if our laboratory fails to comply with the
prescribed quality requirements for laboratory testing or other requirements for CLIA, we could lose CLIA certification. That in turn would impact our ability to
operate our laboratory and provide results to our customers, which could negatively impact our business operations.

The IVDR includes limited exemptions for LDTs, but such exemptions only apply to laboratories that are part of health institutions established in
the EEA, and so any services undertaken outside of the EEA (for example at our facilities in the U.S.) will not be covered by such exemptions. In any event,
such  exemptions  are  limited  in  their  scope,  and  only  apply  if  a  number  of  conditions  are  met,  including  that  the  health  institution  justifies  that  the  “target
patient group’s specific needs cannot be met, or cannot be met at the appropriate level of performance by an equivalent device available on the market” and
do  not  cover  devices  that  are  manufactured  on  an  “industrial  scale”.  Even  where  an  exemption  is  applicable,  such  IVDs  will  still  be  subject  to  certain
requirements under the IVDR. It is therefore unlikely that our tests will benefit from any exemption on the basis of being LDTs and will have to comply with
the IVDR in full if we offer such tests to customers in the EEA (and Northern Ireland) (whether directly or via intermediaries).

If  the  FDA  determines  that  our  services  are  subject  to  enforcement  as  medical  devices,  we  could  incur  substantial  costs  and  time
delays associated with satisfying statutory and regulatory requirements such as pre-market clearance or approval and we could incur
additional expense in offering our tests and tests that we may develop in the future.

If  the  FDA  determines  that  our  tests  and  associated  software  do  not  fall  within  the  definition  of  an  LDT,  or  there  are  regulatory  or  legislative
changes, we may be required to obtain premarket clearance for our tests and associated software under Section 510(k) of the FDC Act or approval of a
premarket approval application (“PMA”). We would also be subject to ongoing regulatory requirements such as registration and listing requirements, medical
device  reporting  requirements,  and  quality  control  requirements.  If  our  tests  are  considered  medical  devices  not  subject  to  enforcement  discretion,  the
regulatory requirements to which our tests are subject would depend on the FDA’s classification of our tests. The FDA has issued regulations classifying over
1,700 different generic types of medical devices into one of three regulatory control categories (Class I, Class II, or Class III) depending on the degree of
regulation  that  the  FDA  finds  necessary  to  provide  reasonable  assurance  of  their  safety  and  effectiveness.  The  class  into  which  a  device  is  placed
determines the requirements that a medical device manufacturer must meet both pre- and post-market.

Generally, Class I devices do not require premarket authorization, but are subject to a comprehensive set of regulatory authorities referred to as
general controls. Class II devices, in addition to general controls, generally require special controls and premarket clearance through the submission of a
section  510(k)  premarket  notification.  Class  III  devices  are  subject  to  general  controls  and  special  controls,  and  also  require  premarket  approval  prior  to
commercial distribution, which is a more rigorous process than premarket clearance. Under the FDC Act, a device that is first marketed after May 28, 1976 is
by default a Class III device requiring premarket approval unless it is within a type of generic device class that has been classified as Class I or Class II.
Even  if  a  device  falls  under  an  existing  Class  II,  non-exempt,  device  classification,  the  product  must  also  be  shown  to  be  “substantially  equivalent”  to  a
legally marketed predicate device through submission of a section 510(k) premarket notification. If after reviewing a firm’s 510(k) premarket notification, the
FDA  determines  that  a  device  is  not  substantially  equivalent  to  a  legally  marketed  predicate  device,  the  new  device  is  classified  into  Class  III,  requiring
premarket approval. It is possible for a manufacturer to obtain a Class I or Class II designation without an appropriate predicate by submitting a de novo
request for reclassification.

The  process  for  submitting  a  510(k)  premarket  notification  and  receiving  FDA  clearance  usually  takes  from  three  to  12  months,  but  it  can  take
significantly longer and clearance is never guaranteed. The process for submitting and obtaining FDA approval of a PMA is much more costly, lengthy, and
uncertain. It generally takes from one to three years or even longer and approval is not guaranteed. PMA approval typically requires extensive clinical data
and  can  be  significantly  longer,  more  expensive  and  more  uncertain  than  the  510(k)  clearance  process.  Despite  the  time,  effort  and  expense  expended,
there can be no assurance that a particular device ultimately will be cleared or approved by the FDA through either the 510(k) clearance process or the PMA
process on a timely basis, or at all.

If  our  tests  are  considered  medical  devices  not  subject  to  enforcement  discretion,  one  classification  regulation  that  could  be  relevant  to  one  or
more of our tests is a recently finalized classification for genetic health risk (“GHR”) assessment tests. On April 6, 2017, in response to a de novo request for
reclassification submitted by another company, the FDA issued an order classifying genetic tests known as genetic health risk assessment systems (“GHR
tests”)  as  Class  II  devices  subject  to  premarket  notification  and  specified  special  controls  requirements.  On  November  7,  2017,  the  FDA  codified  this
classification at 21 C.F.R. § 866.5950. If our tests are considered medical devices that are not subject to enforcement discretion and one or more of our tests
is  considered  to  fall  under  the  21  C.F.R.  §  866.5950  classification  regulation  for  GHR  tests,  or  under  another  Class  II  classification  that  is  subject  to  a
premarket notification requirement, we would be required to obtain marketing clearance for such tests. Further, if considered to fall under the 21 C.F.R. §
866.5950 classification for GHR tests, our tests would be required to adhere to specified special controls, such as labeling and testing specifications and
information about the test to be posted on the manufacturer’s website. If any of our current or pipeline tests

34

are  not  considered  by  the  FDA  to  be  GHR  tests  or  do  not  qualify  for  the  limited  exemption  for  a  sponsor’s  subsequent  GHR  tests  once  the  assessment
system has been reviewed and cleared by FDA, or if any of our tests fall under a different non-exempt classification or are unclassified, we could be required
to obtain 510(k) clearance or approval of a PMA for such test in the future.

If  premarket  review  of  our  tests  is  required,  the  premarket  review  process  may  involve,  among  other  things,  successfully  completing  additional
clinical  trials.  If  we  are  required  to  conduct  premarket  clinical  trials,  whether  using  prospectively  acquired  samples  or  archival  samples,  delays  in  the
commencement or completion of clinical testing could significantly increase our product development costs, delay commercialization of any future products,
and interrupt sales of our current products. Many of the factors that may cause or lead to a delay in the commencement or completion of clinical trials may
also ultimately lead to delay or denial of regulatory clearance or approval. The commencement of clinical trials may be delayed due to insufficient patient
enrollment, which is a function of many factors, including the size of the patient population, the concerns around genetic testing, the nature of the protocol,
the proximity of patients to clinical sites, and the eligibility criteria for the clinical trial.

If we are required to conduct clinical trials, we and any third-party contractors we engage would be required to comply with good clinical practices
(“GCPs”), which are regulations and guidelines enforced by the FDA, for products in clinical development. The FDA enforces these GCPs through periodic
inspections of trial sponsors, principal investigators, and trial sites. If we or any third-party contractor fails to comply with applicable GCPs, the clinical data
generated  in  clinical  trials  may  be  deemed  unreliable  and  the  FDA  may  require  us  to  perform  additional  clinical  trials  before  clearing  or  approving  our
marketing  applications.  A  failure  to  comply  with  these  regulations  may  require  us  to  repeat  clinical  trials,  which  would  delay  the  regulatory  clearance  or
approval process. In addition, if these parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, or if the quality,
completeness or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or for other reasons, our clinical
trials may have to be extended, delayed or terminated. Many of these factors would be beyond our control. We may not be able to enter into replacement
arrangements  without  undue  delays  or  considerable  expenditures.  If  there  are  delays  in  testing  or  approvals  as  a  result  of  the  failure  to  perform  by  third
parties, our research and development costs would increase, and we may not be able to obtain regulatory clearance or approval for our tests. In addition, we
may  not  be  able  to  establish  or  maintain  relationships  with  these  parties  on  favorable  terms,  if  at  all.  Each  of  these  outcomes  would  harm  our  ability  to
market our tests or to achieve or sustain profitability.

The FDA requires medical device manufacturers to comply with, among other things, current good manufacturing practices for medical devices,
set forth in the Quality System Regulation at 21 C.F.R. Part 820, which requires manufacturers to follow elaborate design, testing, control, documentation,
and other quality assurance procedures during the manufacturing process; the medical device reporting regulation, which requires that manufacturers report
to the FDA if their device or a similar device they market may have caused or contributed to a death or serious injury or malfunctioned in a way that would
likely  cause  or  contribute  to  a  death  or  serious  injury  if  it  were  to  recur;  labeling  regulations,  including  the  FDA’s  general  prohibition  against  promoting
products for unapproved or “off-label” uses; the reports of corrections and removals regulation, which requires manufacturers to report to the FDA if a device
correction or removal was initiated to reduce a risk to health posed by the device or to remedy a violation of the FDC Act caused by the device which may
present a risk to health; and the establishment registration and device listing regulation.

Moreover,  there  can  be  no  assurance  that  any  cleared  or  approved  labeling  claims  will  be  consistent  with  our  current  claims  or  adequate  to
support continued adoption of our products. If premarket review is required for some or all of our products, the FDA may require that we stop selling our
products  pending  clearance  or  approval,  which  would  negatively  impact  our  business.  Even  if  our  products  are  allowed  to  remain  on  the  market  prior  to
clearance  or  approval,  demand  for  our  products  may  decline  if  there  is  uncertainty  about  our  products,  if  we  are  required  to  label  our  products  as
investigational by the FDA, or if the FDA limits the labeling claims we are permitted to make for our products. As a result, we could experience significantly
increased development costs and a delay in generating additional revenues from our services, or from other services or products now in development.

In  addition,  any  clearance  or  approval  we  obtain  for  our  products  may  contain  requirements  for  costly  post-market  testing  and  surveillance  to
monitor the safety or efficacy of the product. The FDA has broad post-market enforcement powers, and if unanticipated problems with our products arise, or
if we or our suppliers fail to comply with regulatory requirements following FDA clearance or approval, we may become subject to enforcement actions such
as:

•

•

•

•

•

•

•

•

restrictions on manufacturing processes;

restrictions on product marketing;

warning letters;

withdrawal or recall of products from the market;

refusal to approve pending PMAs, 510(k)s, or supplements to approved PMAs or cleared 510(k)s that we submit;

fines, restitution, or disgorgement of profits or revenue;

suspension or withdrawal of regulatory clearances or approvals;

limitation on, or refusal to permit, import or export of our products;

35

 
 
 
 
 
 
 
 
•

•

•

product seizures;

injunctions; or

imposition of civil or criminal penalties.

Moreover, the FDA strictly regulates the promotional claims that may be made about medical devices. In particular, a medical device may not be
promoted  for  uses  that  are  not  approved  by  the  FDA  as  reflected  in  the  device’s  approved  labeling.  However,  companies  may  share  truthful  and  not
misleading information that is otherwise consistent with the product’s FDA approved labeling. The FDA and other agencies actively enforce the laws and
regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant
civil, criminal, and administrative penalties.

Failure to comply with federal, state, and foreign laboratory licensing requirements and the applicable requirements of the FDA or any
other regulatory authority, could cause us to lose the ability to perform our tests, experience disruptions to our business, or become
subject to administrative or judicial sanctions.

We are subject to CLIA, a federal law that regulates clinical laboratories that perform testing on specimens derived from humans for the purpose
of  providing  information  for  the  diagnosis,  prevention,  or  treatment  of  disease.  CLIA  regulations  establish  specific  standards  with  respect  to  personnel
qualifications, facility administration, proficiency testing, quality control, quality assurance, and inspections. We have a current CLIA certificate to conduct our
tests  at  our  laboratory  in  Menlo  Park,  California.  To  renew  this  certificate,  we  are  subject  to  survey  and  inspection  every  two  years.  Moreover,  CLIA
inspectors may make random inspections of our clinical reference laboratory.

We  are  also  required  to  maintain  a  license  to  conduct  testing  in  California.  California  laws  establish  standards  for  day-to-day  operation  of  our
clinical  reference  laboratory  in  Menlo  Park,  including  the  training  and  skills  required  of  personnel  and  quality  control.  Several  other  states  in  which  we
operate also require that we hold licenses to test specimens from patients in those states, under certain circumstances. For example, our clinical reference
laboratory is required to be licensed on a product-specific basis by New York as an out-of-state laboratory, and our products, as LDTs, must be approved by
the  New  York  State  Department  of  Health  (the  “NYDOH”)  on  a  product-by-product  basis  before  they  are  offered  in  New  York.  We  are  subject  to  periodic
inspection by the NYDOH and are required to demonstrate ongoing compliance with NYDOH regulations and standards. To the extent NYDOH identified any
non-compliance  and  we  are  unable  to  implement  satisfactory  corrective  actions  to  remedy  such  non-compliance,  the  State  of  New  York  could  withdraw
approval for our tests. Additionally, states such as Maryland, Pennsylvania, and Rhode Island may also require us to maintain out-of-state licenses. Other
states may have similar requirements or may adopt similar requirements in the future. Although we have obtained licenses from states where we believe we
are required to be licensed, we may become aware of other states that require out-of-state laboratories to obtain licensure in order to accept specimens from
the  state,  and  it  is  possible  that  other  states  currently  have  such  requirements  or  will  have  such  requirements  in  the  future.  We  may  also  be  subject  to
regulation in foreign jurisdictions as we seek to expand international utilization of our tests or such jurisdictions adopt new licensure requirements, which may
require review  of  our  tests  in  order  to  offer  them  or  may  have  other  limitations  such  as  restrictions  on  the  transport  of  human  blood  necessary  for  us  to
perform our tests that may limit our ability to make our tests available outside of the U.S. Complying with licensure requirements in new jurisdictions may be
expensive and/or time-consuming, may subject us to significant and unanticipated delays, or may be in conflict with other applicable requirements.

Failure  to  comply  with  applicable  clinical  laboratory  licensure  requirements  may  result  in  a  range  of  enforcement  actions,  including  license
suspension, limitation, or revocation, directed plan of action, onsite monitoring, civil monetary penalties, and criminal sanctions as well as significant adverse
publicity. Any sanction imposed under CLIA, its implementing regulations or state or foreign laws or regulations governing clinical laboratory licensure, or our
failure to renew our CLIA certificate, a state or foreign license or accreditation, could have a material adverse effect on our business, financial condition, and
results of operations. Even if we were able to bring our laboratory back into compliance, we could incur significant expenses and potentially lose revenues in
doing so.

Failure to comply with the IVDR may result in a range of enforcement actions. Penalties under the IVDR are devolved to national governments,
but the IVDR requires that such measures are “effective, proportionate, and dissuasive.” Initial indications suggest that penalties for breaches of the IVDR
are likely to include fines and, potentially, prison sentences.

Although we market our tests as LDTs that are currently subject to the FDA’s exercise of enforcement discretion, if we fail to operate within the
conditions of that exercise of enforcement discretion, or if any of our products otherwise fail to comply with FDA regulatory requirements as enforced, we
would be subject to the applicable requirements of the FDC Act and the FDA’s implementing regulations. The FDA is empowered to impose sanctions for
violations of the FDC Act and the FDA’s implementing regulations, including warning letters, civil and criminal penalties, injunctions, product seizure or recall,
import bans, restrictions on the conduct of our operations and total or partial suspension of production. Any of the aforementioned sanctions could cause
reputational damage, undermine our ability to maintain and increase our revenues, and harm our business, financial condition, and results of operations. In
particular,  if  we  or  the  FDA  discover  that  any  of  our  products  have  defects  that  call  into  question  the  accuracy  of  their  results,  we  may  be  required  to
undertake a retest of all results and analyses provided during the period relevant to the defect, or recall the affected products. The direct costs incurred in
connection  with  such  a  recall  in  terms  of  management  time,  administrative,  and  legal  expenses  and  lost  revenue,  together  with  the  indirect  costs  to  our
reputation could harm our business, financial condition, and results of operations, and our ability to execute our business strategy. While we believe that we
are currently in material compliance with applicable laws and regulations as currently enforced, the FDA or other regulatory agencies may not agree, and a
determination that

36

 
 
 
 
we  have  violated  these  laws  or  a  public  announcement  that  we  are  being  investigated  for  possible  violations  of  these  laws  could  adversely  affect  our
business, financial condition, results of operations, and prospects.

If our security measures are compromised, or our information technology systems or those of our vendors, and other relevant third
parties fail or suffer security breaches, loss or leakage of data, and other disruptions, this could result in a material disruption of our
services, compromise sensitive information related to our business, harm our reputation, trigger breach notification obligations,
prevent us from accessing critical information, and expose us to liability or other adverse effects to our business.

In the ordinary course of our business, we collect, process, and store proprietary, confidential, and sensitive information, including protected health
information (“PHI”), personally identifiable information (“PII”), credit card and other financial information, intellectual property, trade secrets, and proprietary
business information owned or controlled by ourselves or our customers, payors, and other parties. It is critical that we do so in a secure manner to maintain
the  confidentiality,  integrity,  and  availability  of  such  information.  We  depend  on  information  technology  and  telecommunications  systems  for  significant
elements of our operations and we have installed, and expect to expand, a number of enterprise software systems that affect a broad range of business
processes  and  functional  areas,  including,  for  example,  systems  handling  human  resources,  financial  reporting  and  controls,  customer  relationship
management, regulatory compliance, and other infrastructure operations. We face a number of risks relative to protecting this critical information, including
loss of access risk, inappropriate use or disclosure, inappropriate modification, and the risk of our being unable to adequately monitor, audit, and modify our
controls over our critical information. This risk extends to the third-party vendors and subcontractors, as we have outsourced elements of our operations to
third parties and as a result a number of third-party vendors and other contractors and consultants have access to our proprietary, confidential, and sensitive
information.

We manage and maintain our applications and data utilizing a combination of on-site systems and cloud-based data centers. We utilize external
security  and  infrastructure  vendors  to  manage  parts  of  our  data  centers.  We  also  communicate  sensitive  data,  including  patient  data,  electronically,  and
through relationships with multiple third-party vendors and their subcontractors. These applications and data encompass a wide variety of business-critical
information,  including  research  and  development  information,  patient  data,  commercial  information,  and  business  and  financial  information.  Despite  the
precautionary  measures  we  have  taken  to  prevent  unanticipated  problems  that  could  affect  our  information  technology  and  telecommunications  systems,
failures  or  significant  downtime  of  our  information  technology  or  telecommunications  systems  or  those  used  by  our  third-party  service  providers  could
prevent  us  from  conducting  tests,  preparing  and  providing  reports  to  our  customers,  billing  customers,  collecting  revenue,  handling  inquiries  from  our
customers, conducting research and development activities, and managing the administrative aspects of our business. For example, in the first quarter of
2018,  we  experienced  downtime  in  our  information  technology  systems  in  connection  with  the  adoption  of  certain  new  information  technology,  and  our
results  of  operations  in  the  first  and  second  quarters  of  2018  were  adversely  affected  as  a  result.  Any  disruption  or  loss  of  information  technology  or
telecommunications systems on which critical aspects of our operations depend could have an adverse effect on our business.

Notwithstanding the implementation of security measures, given the size and complexity of our internal information technology systems and those
of our third-party vendors and other contractors and consultants, and the increasing amounts of proprietary, confidential, and sensitive information that they
maintain,  such  information  technology  systems  are  potentially  vulnerable  to  breakdown,  service  interruptions,  system  malfunction,  natural  disasters,
terrorism,  war,  and  telecommunication  and  electrical  failures,  as  well  as  security  breaches  from  inadvertent  or  intentional  actions  by  our  personnel,  third-
party  vendors,  contractors,  consultants,  business  partners,  and/or  other  third  parties,  or  from  cyber-attacks  by  malicious  third  parties  (including  the
deployment  of  harmful  malware,  ransomware,  denial-of-service  attacks,  social  engineering,  and  other  means  to  affect  service  reliability  and  threaten  the
confidentiality,  integrity,  and  availability  of  information),  which  may  compromise  our  system  infrastructure,  or  that  of  our  third-party  vendors  and  other
contractors  and  consultants,  or  lead  to  data  leakage.  The  risk  of  a  security  breach  or  disruption,  particularly  through  accidental  actions  or  omissions  by
trusted  insiders,  cyber-attacks  or  cyber  intrusions,  including  by  computer  hackers,  viruses,  foreign  governments,  and  cyber  terrorists,  has  generally
increased as the number, intensity, and sophistication of attempted attacks and intrusions from around the world have increased; in particular, during the
COVID-19 pandemic we have observed an increase in attempted attacks against our data systems. Additionally, in connection with the ongoing COVID-19
pandemic,  most  of  our  personnel  are  working  remotely,  which  may  increase  the  risk  of  security  breaches,  loss  of  data,  and  other  disruptions  as  a
consequence of more personnel accessing sensitive and critical information from remote locations. We may not be able to anticipate all types of security
threats,  and  we  may  not  be  able  to  implement  preventive  measures  effective  against  all  such  security  threats.  The  techniques  used  by  cyber  criminals
change frequently, may not be recognized until launched, and can originate from a wide variety of sources, including outside groups such as external service
providers,  organized  crime  affiliates,  terrorist  organizations,  hostile  foreign  governments  or  agencies,  or  cybersecurity  researchers.  To  the  extent  that  any
disruption or security breach were to result in a loss of, or damage to, our data or applications, or those of our third-party vendors and other contractors and
consultants,  or  inappropriate  disclosure  of  confidential  or  proprietary  information,  we  could  incur  liability  and  reputational  damage  and  the  further
development and commercialization of our services could be delayed. The costs related to significant security breaches or disruptions could be material and
exceed the limits of the cybersecurity insurance we maintain against such risks. If the information technology systems of our third-party vendors and other
contractors and consultants become subject to disruptions or security breaches, we may have insufficient recourse against such third parties and we may
have  to  expend  significant  resources  to  mitigate  the  impact  of  such  an  event,  and  to  develop  and  implement  protections  to  prevent  future  events  of  this
nature from occurring.

We  cannot  assure  you  that  our  data  protection  efforts  and  our  investment  in  information  technology  will  prevent  significant  breakdowns,  data
leakages,  breaches  in  our  systems,  or  those  of  our  third-party  vendors  and  other  contractors  and  consultants,  or  other  cyber  incidents  that  could  have  a
material adverse effect upon our reputation, business, operations, or financial condition. For example, if such an event were to occur and cause interruptions
in our operations, or those of our third-party vendors and other

37

contractors and consultants, it could result in a material disruption of our programs and the development of our services and technologies could be delayed.
Furthermore, significant disruptions of our internal information technology systems or those of our third-party vendors and other contractors and consultants,
or security breaches could result in the loss, misappropriation, and/or unauthorized access, use, or disclosure of, or the prevention of access to, confidential
information (including trade secrets or other intellectual property, proprietary business information, and personal information), which could result in financial,
legal,  business,  and  reputational  harm  to  us.  For  example,  any  such  event  that  leads  to  unauthorized  access,  use,  or  disclosure  of  personal  information,
including  personal  information  regarding  our  customers  or  employees,  could  harm  our  reputation  directly,  compel  us  to  comply  with  federal  and/or  state
breach  notification  laws  and  foreign  law  equivalents,  subject  us  to  mandatory  corrective  action,  and  otherwise  subject  us  to  liability  under  laws  and
regulations  that  protect  the  privacy  and  security  of  personal  information,  which  could  result  in  significant  legal  and  financial  exposure  and  reputational
damages that could potentially have an adverse effect on our business.

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 personnel 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 proceedings, liability under domestic or foreign privacy, data
protection, and data security laws such as the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) and the Health Information Technology
for Economic and Clinical Health Act (“HITECH”), and penalties. Notice of certain security breaches must be made to affected individuals, the Secretary of
the Department of Health and Human Services (“HHS”), 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. Although we have implemented security measures and a formal, dedicated enterprise
security program to prevent unauthorized access to patient data, such data is currently accessible through multiple channels, and there is no guarantee we
can  protect  our  data  from  breach.  Unauthorized  access,  loss,  or  dissemination  could  also  damage  our  reputation  or  disrupt  our  operations,  including  our
ability to conduct our analyses, deliver test results, process claims and appeals, provide customer assistance, conduct research and development activities,
collect,  process,  and  prepare  company  financial  information,  provide  information  about  our  tests  and  other  patient  and  physician  education  and  outreach
efforts through our website, and manage the administrative aspects of our business.

Penalties for violations of these laws vary. For instance, penalties for failure to comply with a requirement of HIPAA and HITECH vary significantly,
and include significant civil monetary penalties and, in certain circumstances, criminal penalties with fines up to $250,000 per violation and/or imprisonment.
A person who knowingly obtains or discloses individually identifiable health information in violation of HIPAA may face a criminal penalty of up to $50,000
and  up  to  one-year  imprisonment.  The  criminal  penalties  increase  if  the  wrongful  conduct  involves  false  pretenses  or  the  intent  to  sell,  transfer  or  use
identifiable health information for commercial advantage, personal gain or malicious harm.

Further,  various  states,  such  as  California  and  Massachusetts,  have  implemented  similar  privacy  laws  and  regulations,  such  as  the  California
Confidentiality of Medical Information Act, that impose restrictive requirements regulating the use and disclosure of health information and other personally
identifiable information. These laws and regulations are not necessarily preempted by HIPAA, particularly if a state affords greater protection to individuals
than HIPAA. Where state laws are more protective, we have to comply with the stricter provisions. In addition to fines and penalties imposed upon violators,
some  of  these  state  laws  also  afford  private  rights  of  action  to  individuals  who  believe  their  personal  information  has  been  misused.  California’s  patient
privacy laws, for example, provide for penalties of up to $250,000 and permit injured parties to sue for damages. Similarly, the California Consumer Privacy
Act  (“CCPA”)  allows  consumers  a  private  right  of  action  when  certain  personal  information  is  subject  to  unauthorized  access  and  exfiltration,  theft  or
disclosure due to a business’ failure to implement and maintain reasonable security procedures. The interplay of federal and state laws may be subject to
varying  interpretations  by  courts  and  government  agencies,  creating  complex  compliance  issues  for  us  and  data  we  receive,  use  and  share,  potentially
exposing  us  to  additional  expense,  adverse  publicity  and  liability.  Further,  as  regulatory  focus  on  privacy  issues  continues  to  increase  and  laws  and
regulations  concerning  the  protection  of  personal  information  expand  and  become  more  complex,  these  potential  risks  to  our  business  could  intensify.
Changes in laws or regulations associated with the enhanced protection of certain types of sensitive data, such as PHI or PII, for the treatment of genetic
data, along with increased customer demands for enhanced data security infrastructure, could greatly increase our cost of providing our services, decrease
demand for our services, reduce our revenues and/or subject us to additional liabilities.

The actual or perceived failure by us, our customers, or vendors to comply with increasingly stringent laws, regulations and contractual
obligations relating to privacy, data protection, and data security could harm our reputation, and subject us to significant fines and
liability.

We are subject to numerous domestic and foreign laws and regulations regarding privacy, data protection, and data security, the scope of which is
changing, subject to differing applications and interpretations and may be inconsistent among countries, or conflict with other rules. We are also subject to
the terms of our contractual obligations to customers and third parties related to privacy, data protection, and data security. The actual or perceived failure by
us,  our  customers,  our  vendors,  or  other  relevant  third  parties  to  address  or  comply  with  these  laws,  regulations,  and  obligations  could  increase  our
compliance  and  operational  costs,  expose  us  to  regulatory  scrutiny,  actions,  fines  and  penalties,  result  in  reputational  harm,  lead  to  a  loss  of  customers,
reduce the use of our services, result in litigation and liability, and otherwise cause a material adverse effect on our business, financial condition, and results
of operations.

38

For  example,  the  EU  adopted  the  General  Data  Protection  Regulation  (EU)  2016/679  (“GDPR”),  which  imposes  onerous  and  comprehensive
privacy, data protection, and data security obligations onto data controllers and processors, including, as applicable, contractual privacy, data protection, and
data security commitments, expanded disclosures to data subjects about how their personal information is used, honoring individuals’ data protection rights,
limitations on retention of personal information, additional requirements pertaining to sensitive information (such as health data) and pseudonymized (i.e.,
key-coded) data, data breach notification requirements, and higher standards for obtaining consent from data subjects. Penalties for non-compliance with the
GDPR  can  be  significant  and  include  fines  in  the  amount  of  the  greater  of  €20  million  or  4%  of  global  turnover  and  restrictions  or  prohibitions  on  data
processing,  which  could  limit  our  ability  to  do  business  in  the  EU,  reduce  demand  for  our  services,  and  adversely  impact  our  business  and  results  of
operations.  The  GDPR  also  provides  that  EU  member  states  may  introduce  further  conditions,  including  limitations,  to  make  their  own  further  laws  and
regulations limiting the processing of genetic, biometric, or health data, which could limit our ability to collect, use and share European data, or could cause
our  compliance  costs  to  increase,  require  us  to  change  our  practices,  adversely  impact  our  business,  and  harm  our  financial  condition.  Assisting  our
customers, partners, and vendors in complying with the GDPR, or complying with the GDPR ourselves, may cause us to incur substantial operational costs
or require us to change our business practices.

European  privacy,  data  protection,  and  data  security  laws,  including  the  GDPR,  generally  restrict  the  transfer  of  personal  information  from  the
U.K.,  EEA  and  Switzerland  to  the  U.S.  and  most  other  countries  unless  the  parties  to  the  transfer  have  implemented  specific  safeguards  to  protect  the
transferred  personal  information.  There  is  uncertainty  on  how  to  implement  such  safeguards  and  how  to  conduct  such  transfers  in  compliance  with  the
GDPR, and certain safeguards may not be available or applicable with respect to some or all of the personal information processing activities necessary to
research,  develop  and  market  our  products  and  services.  One  of  the  primary  safeguards  allowing  U.S.  companies  to  import  personal  information  from
Europe  has  been  certification  to  the  EU-U.S.  Privacy  Shield  and  Swiss-U.S.  Privacy  Shield  frameworks.  However,  the  EU-U.S.  Privacy  Shield  framework
was invalidated in July 2020 in a decision by the Court of Justice of the EU and the Swiss-U.S. Privacy Shield Framework was declared as inadequate by
the Swiss Federal Data Protection and Information Commissioner. The decision by the Court of Justice and the announcement by the Swiss Commissioner
both raised questions about whether one of the primary alternatives to the Privacy Shield frameworks, the European Commission’s Standard Contractual
Clauses,  can  lawfully  be  used  for  personal  information  transfers  from  Europe  to  the  U.S.  or  most  other  countries.  Authorities  in  the  U.K.  may  similarly
invalidate  use  of  the  EU-U.S.  Privacy  Shield  and  raise  questions  on  the  viability  of  the  Standard  Contractual  Clauses.  In  November  2020,  EU  regulators
proposed a new set of Standard Contractual Clauses, which impose additional obligations and requirements with respect to the transfer of EU personal data
to other jurisdictions, which may increase the legal risks and liabilities under the GDPR and local EU laws associated with cross-border data transfers, and
result in material increased compliance and operational costs. If we are unable to implement a valid solution for personal information transfers to the U.S.
and  other  countries,  we  will  face  increased  exposure  to  regulatory  actions,  substantial  fines,  and  injunctions  against  processing  or  transferring  personal
information from Europe, and we may be required to increase our data processing capabilities in Europe at significant expense. Inability to import personal
information from Europe to the U.S. or other countries may decrease demand for our products and services as our customers that are subject to the GDPR
may seek alternatives that do not involve personal information transfers out of Europe. At present, there are few, if any, viable alternatives to the Privacy
Shield and the Standard Contractual Clauses.

In addition, it is unclear whether the transfer of personal information from the EU to the U.K. will continue to remain lawful under the GDPR in light
of Brexit. Pursuant to a post-Brexit trade deal between the U.K. and the EU, transfers of personal information from the EEA to the U.K. are not considered
restricted transfers under the GDPR for a period of up to six months from January 1, 2021. However, unless the EU Commission makes an adequacy finding
with  respect  to  the  U.K.  before  the  end  of  that  period,  the  U.K.  will  be  considered  a  “third  country”  under  the  GDPR  and  transfers  of  European  personal
information  to  the  U.K.  will  require  an  adequacy  mechanism  to  render  such  transfers  lawful  under  the  GDPR.  Additionally,  although  U.K.  privacy,  data
protection and data security law is designed to be consistent with the GDPR, uncertainty remains regarding how data transfers to and from the U.K. will be
regulated notwithstanding Brexit.

Regulation of privacy, data protection, and data security has also become more stringent in the U.S. New laws are also being considered at both
the  state  and  federal  levels,  and  legislatures  of  states  such  as  California  have  already  passed  and  enacted  privacy  legislation.  For  example,  the  CCPA,
which took effect on January 1, 2020, gives California residents expanded rights to access and delete their personal information, opt out of certain personal
information sharing, and receive detailed information about how their personal information is used. The CCPA provides for civil penalties for violations, as
well  as  a  private  right  of  action  for  data  breaches  that  is  expected  to  increase  data  breach  litigation.  The  CCPA  may  increase  our  compliance  costs  and
potential liability. Some observers have noted that the CCPA could mark the beginning of a trend toward more stringent state privacy, data protection and
data security legislation in the U.S., which could increase our potential liability and adversely affect our business. The CCPA will be expanded substantially
on January 1, 2023, when the California Privacy Rights Act of 2020 (“CPRA”) becomes fully operative. The CPRA imposes additional obligations relating to
consumer data on companies doing business in California beginning January 1, 2022, with implementing regulations expected on or before July 1, 2022, and
enforcement beginning July 1, 2023. The CPRA significantly modifies the CCPA and will, among other things, give California residents the ability to limit use
of certain sensitive personal information, further restrict the use of cross-contextual advertising, establish restrictions on the retention of personal information,
expand the types of data breaches subject to the CCPA’s private right of action, provide for increased penalties for CPRA violations concerning California
residents under the age of 16, and establish a new California Privacy Protection Agency to implement and enforce the new law.

Compliance  with  U.S.  and  foreign  privacy,  data  protection,  and  data  security  laws  and  regulations  could  cause  us  to  incur  substantial  costs  or
require us to change our business practices and compliance procedures in a manner adverse to our business. Moreover, complying with these various laws
could require us to take on more onerous obligations in our contracts, restrict our ability to

39

collect, use and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. We typically rely on our customers to obtain valid and
appropriate consents from data subjects whose genetic samples and data we process on such customers’ behalf. Given that we do not typically obtain direct
consent from such data subjects and we do not audit our customers to ensure that they have obtained the necessary consents required by law, the failure of
our customers to obtain consents that are valid under applicable law could result in our own non-compliance with privacy laws. Such failure to comply with
U.S. and foreign privacy, data protection, and data security laws and regulations could result in government enforcement actions (which could include civil or
criminal penalties), private litigation and/or adverse publicity and could negatively affect our operating results and business. Claims that we have violated
individuals’ privacy rights, failed to comply with privacy, data protection, and data security laws, or breached our contractual obligations, even if we are not
found liable, could be expensive and time consuming to defend, could result in adverse publicity and could have a material adverse effect on our business,
financial condition, and results of operations.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and
requirements, which could cause significant liability for us and harm our reputation.

We are exposed to the risk of employee fraud or other misconduct, including intentional failures to comply with government regulations, including
federal and state healthcare fraud and abuse laws and regulations, to misuse information, including patient information, and to report financial information or
data  accurately  or  disclose  unauthorized  activities  to  us.  Such  misconduct  could  also  involve  the  improper  use  of  information  obtained  in  the  course  of
clinical studies, which could result in regulatory sanctions and cause serious harm to our reputation. We have a code of conduct and ethics for our directors,
officers  and  employees,  but  it  is  not  always  possible  to  identify  and  deter  employee  misconduct,  and  the  precautions  we  take  to  detect  and  prevent  this
activity may not be effective in controlling risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a
failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or
asserting  our  rights,  those  actions  could  have  a  significant  impact  on  our  business  and  results  of  operations,  including  the  imposition  of  significant
administrative, civil and criminal penalties, damages, fines, imprisonment, exclusion from government healthcare programs, contractual damages, refunding
of payments received by us, reputational harm, additional reporting, or oversight obligations if we become subject to a corporate integrity agreement or other
agreement  to  resolve  allegations  of  non-compliance  with  the  law  and  curtailment  or  restructuring  of  our  operations.  Whether  or  not  we  are  successful  in
defending against such actions or investigations, we could incur substantial costs, including legal fees, and divert the attention of management in defending
ourselves against any of these claims or investigations.

Complying with numerous statutes and regulations pertaining to our business is an expensive and time-consuming process, and any
failure to comply could result in substantial penalties.

Our operations may be subject to other extensive federal, state, local, and foreign laws and regulations, all of which are subject to change. These

laws and regulations currently include, among others:

•

•

•

•

•

the federal  Anti-Kickback  Statute,  which  prohibits  knowingly  and  willfully  offering,  paying,  soliciting,  or  receiving  remuneration,  directly  or
indirectly,  overtly  or  covertly,  in  cash  or  in  kind,  in  return  for  or  to  induce  such  person  to  refer  an  individual,  or  to  purchase,  lease,  order,
arrange for, or recommend purchasing, leasing or ordering, any good, facility, item or service that is reimbursable, in whole or in part, under a
federal healthcare program. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to
have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the
federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the false claims statutes;

the federal Stark physician self-referral law, which prohibits a physician from making a referral for certain designated health services covered
by  the  Medicare  program,  including  laboratory  and  pathology  services,  if  the  physician  or  an  immediate  family  member  has  a  financial
relationship  with  the  entity  providing  the  designated  health  services,  and  prohibits  that  entity  from  billing  or  presenting  a  claim  for  the
designated health services furnished pursuant to the prohibited referral, unless an exception applies. Failure to refund amounts received as a
result of a prohibited referral on a timely basis may constitute a false or fraudulent claim under the False Claims Act;

the “Anti-Markup Rule” and similar state laws, among other things, prohibit a physician or supplier billing the Medicare program from marking
up the price of a purchased diagnostic service performed by another laboratory or supplier that does not “share a practice” with the billing
physician or supplier. Penalties may apply to the billing physician or supplier if Medicare or another payer is billed at a rate that exceeds the
performing laboratory’s charges to the billing physician or supplier, and the performing laboratory could be at risk under false claims laws,
described below, for causing the submission of a false claim;

the  federal  civil  and  criminal  false  claims  laws,  including  the  False  Claims  Act,  which  impose  liability  on  any  person  or  entity  that,  among
other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment to the federal government. These laws
can  apply  to  entities  that  provide  information  on  coverage,  coding,  and  reimbursement  of  their  products  and  assistance  with  obtaining
reimbursement to persons who bill payors. Private individuals can bring False Claims Act “qui tam” actions, on behalf of the government and
such individuals, commonly known as “whistleblowers,” may share in amounts paid by the entity to the government in fines or settlement;

the federal Civil Monetary Penalties Law, which prohibits, among other things, the offering or transfer of remuneration to a Medicare or state
healthcare program beneficiary if the person knows or should know it is likely to influence the

40

 
 
 
 
 
beneficiary’s selection of a particular provider, practitioner, or supplier of services reimbursable by Medicare or a state healthcare program,
unless an exception applies;

he  federal  Physician  Payments  Sunshine  Act,  which  requires  certain  manufacturers  of  drugs,  biologicals,  and  medical  devices  or  supplies
that require premarket approval by or notification to the FDA, and for which payment is available under Medicare, Medicaid, or the Children’s
Health Insurance Program (“CHIP”), with certain exceptions, to report annually to CMS information related to (i) payments and other transfers
of  value  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists,  and  chiropractors)  and  teaching  hospitals,  and
(ii) ownership and investment interests held by physicians and their immediate family members, which will be expanded beginning in 2022, to
require  applicable  manufacturers  to  report  information  regarding  payments  and  other  transfers  of  value  provided  to  physician  assistants,
nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiologist assistants, and certified nurse midwives
during the previous year;

the  HIPAA  fraud  and  abuse  provisions,  which  created  federal  civil  and  criminal  statutes  that  prohibit,  among  other  things,  defrauding
healthcare  programs,  willfully  obstructing  a  criminal  investigation  of  a  healthcare  offense,  and  falsifying  or  concealing  a  material  fact  or
making any materially false statements in connection with the payment for healthcare benefits, items or services. Similar to the federal Anti-
Kickback  Statute,  a  person  or  entity  does  not  need  to  have  actual  knowledge  of  the  statute  or  specific  intent  to  violate  it  in  order  to  have
committed a violation;

the  Eliminating  Kickbacks  in  Recovery  Act  of  2018  (“EKRA”),  which  prohibits  payments  for  referrals  to  recovery  homes,  clinical  treatment
facilities, and laboratories. EKRA’s reach extends beyond federal health care programs to include private insurance (i.e., it is an “all payer”
statute);

other  federal  and  state  fraud  and  abuse  laws,  such  as  anti-kickback  laws,  prohibitions  on  self-referral,  fee-splitting  restrictions,  insurance
fraud laws, prohibitions on the provision of tests at no or discounted cost to induce physician or patient adoption, and false claims acts, which
may extend to services reimbursable by any payer, including private insurers;

the prohibition on reassignment of Medicare claims, which, subject to certain exceptions, precludes the reassignment of Medicare claims to
any other party;

state  laws  that  prohibit  other  specified  practices,  such  as  billing  physicians  for  testing  that  they  order;  waiving  coinsurance,  copayments,
deductibles, and other amounts owed by patients; billing a state Medicaid program at a price that is higher than what is charged to one or
more  other  payors;  employing,  exercising  control  over,  licensed  professionals  in  violation  of  state  laws  prohibiting  corporate  practice  of
medicine and other professions, and prohibitions against the splitting of professional fees with licensed professionals; and

similar foreign laws and regulations that apply to us in the countries in which we operate or may operate in the future.

As  a  clinical  laboratory,  our  business  practices  may  face  additional  scrutiny  from  government  regulatory  agencies  such  as  the  Department  of
Justice, the HHS Office of Inspector General (the “OIG”), and CMS. Certain arrangements between clinical laboratories and referring physicians have been
identified in fraud alerts issued by the OIG as implicating the Anti-Kickback Statute. The OIG has stated that it is particularly concerned about these types of
arrangements because the choice of laboratory, as well as the decision to order laboratory tests, typically are made or strongly influenced by the physician,
with little or no input from patients. Moreover, the provision of payments or other items of value by a clinical laboratory to a referral source could be prohibited
under the Stark Law unless the arrangement meets all criteria of an applicable exception. The government has been active in enforcement of these laws as
they apply to clinical laboratories.

The growth of our business and our expansion outside of the U.S. may increase the potential of violating these laws or our internal policies and
procedures.  The  risk  of  our  being  found  in  violation  of  these  or  other  laws  and  regulations  is  further  increased  by  the  fact  that  many  have  not  been  fully
interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Any action brought against us for violation
of these or other laws or regulations, even if we successfully defend against it, could cause us to incur significant legal expenses and reputational harm and
divert our management’s attention from the operation of our business. If our operations are found to be in violation of any of these laws and regulations, we
may  be  subject  to  any  applicable  penalty  associated  with  the  violation,  including  significant  administrative,  civil  and  criminal  penalties,  damages,  fines,
imprisonment,  exclusion  from  participation  in  federal  healthcare  programs,  refunding  of  payments  received  by  us,  integrity  oversight  and  reporting
obligations, and curtailment or cessation of our operations. Any of the foregoing consequences could seriously harm our business and our financial results.

We could be adversely affected by violations of the Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”), and other
worldwide anti-bribery laws.

We are subject to the FCPA, which prohibits companies and their intermediaries from making payments in violation of law to non-U.S. government
officials  for  the  purpose  of  obtaining  or  retaining  business  or  securing  any  other  improper  advantage.  Other  U.S.  companies  in  the  medical  device  and
pharmaceutical fields have faced criminal penalties under the FCPA for allowing their agents to deviate from appropriate practices in doing business with
these individuals. We are also subject to similar anti-bribery laws in the jurisdictions in which we operate, including the U.K.’s Bribery Act of 2010, which also
prohibits commercial bribery and makes it a crime

41

 
 
 
 
 
 
 
 
for companies to fail to prevent bribery. These laws are complex and far-reaching in nature, and, as a result, we cannot assure you that we would not be
required in the future to alter one or more of our practices to be in compliance with these laws or any changes in these laws or the interpretation thereof. Any
violations of these laws, or allegations of such violations, could disrupt our operations, involve significant management distraction, involve significant costs
and expenses, including legal fees, and could result in a material adverse effect on our business, prospects, financial condition or results of operations. We
could also incur severe penalties, including criminal and civil penalties, disgorgement, and other remedial measures.

If we decide to grow our business by developing in vitro diagnostic tests, we may be subject to reimbursement challenges.

The coverage and reimbursement status of newly approved or cleared laboratory tests, including our NeXT Dx test, is uncertain. If we decide to
seek  reimbursement  for  our  NeXT  Dx  test  or  other  in  vitro  diagnostic  tests  we  may  develop,  and  if  such  tests  are  inadequately  covered  by  insurance  or
ineligible for such reimbursement, this could limit our ability to market any such future tests. The commercial success of future products in both domestic and
international markets may depend in part on the availability of coverage and adequate reimbursement from third-party payors, including government payors,
such as the Medicare and Medicaid programs, managed care organizations, and other third-party payors. The government and other third-party payors are
increasingly attempting to contain health care costs by limiting both insurance coverage and the level of reimbursement for new diagnostic tests. As a result,
they may not cover or provide adequate payment for any future in vitro diagnostic tests that we develop. These payors may conclude that our products are
less safe, less effective, or less cost-effective than existing or later-introduced products. These payors may also conclude that the overall cost of using one of
our  tests  exceeds  the  overall  cost  of  using  a  competing  test,  and  third-party  payors  may  not  approve  any  future  in  vitro  diagnostic  tests  we  develop  for
insurance coverage and adequate reimbursement.

Changes in health care policy could increase our costs, decrease our revenues, and impact sales of and reimbursement for our tests.

In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (the “ACA”),
became law. This law substantially changed the way health care is financed by both commercial payers and government payers, and significantly impacts
our industry. The ACA contains a number of provisions that are expected to impact the business and operations of our customers, some of which in ways we
cannot  currently  predict,  including  those  governing  enrollment  in  state  and  federal  health  care  programs,  reimbursement  changes,  and  fraud  and  abuse,
which will impact existing state and federal health care programs and will result in the development of new programs.

Among other things, the ACA:

•

•

•

expanded eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals
and  by  adding  new  mandatory  eligibility  categories  for  individuals  with  income  at  or  below  133%  of  the  federal  poverty  level,  thereby
potentially increasing manufacturers’ Medicaid rebate liability;

established a new Patient-Centered Outcomes Research Institute to oversee and identify priorities in comparative clinical efficacy research in
an effort to coordinate and develop such research; and

established a Center for Medicare and Medicaid Innovation at CMS to test innovative payment and service delivery models to lower Medicare
and Medicaid spending.

There remain judicial and Congressional challenges to certain aspects of the ACA, as well as efforts by the former Trump administration to repeal
or  replace  certain  aspects  of  the  ACA.  Since  January  2017,  former  President  Trump  signed  several  Executive  Orders  and  other  directives  to  delay  the
implementation of certain requirements of the ACA. Concurrently, Congress considered legislation that would repeal, or repeal and replace, all or part of the
ACA. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA such as removing
penalties,  starting  January  1,  2019,  for  not  complying  with  the  ACA’s  individual  mandate  to  carry  health  insurance  and  eliminating  the  implementation  of
certain  ACA-mandated  fees.  On  December  14,  2018,  a  Texas  U.S.  District  Court  Judge  ruled  that  the  ACA  is  unconstitutional  in  its  entirety  because  the
“individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act. Additionally, on December 18, 2019, the U.S. Court of Appeals for the
5th Circuit upheld the District Court ruling that the individual mandate was unconstitutional and remanded the case back to the District Court to determine
whether the remaining provisions of the ACA are invalid as well. The U.S. Supreme Court is currently reviewing the case, although it is uncertain when or
how the Supreme Court will rule. It is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the ACA will impact the ACA
and our business. Additional legislation may be enacted that further amends, or repeals, the ACA, which could result in lower numbers of insured individuals,
reduced coverage for insured individuals and adversely affect our and our customers’ business.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On August 2, 2011, the Budget Control Act of
2011 was signed into law, which, among other things, reduced Medicare payments to providers by 2% per fiscal year, effective on April 1, 2013 and, due to
subsequent  legislative  amendments  to  the  statute,  will  remain  in  effect  through  2030,  with  the  exception  of  a  temporary  suspension  from  May  1,  2020
through March 31, 2021, unless additional Congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into
law, which, among other things, reduced Medicare payments to several providers, including hospitals, and increased the statute of limitations period for the
government  to  recover  overpayments  to  providers  from  three  to  five  years.  The  Medicare  Access  and  CHIP  Reauthorization  Act  of  2015,  enacted  on
April 16, 2015 (“MACRA”), repealed the formula by which Medicare made annual payment adjustments to physicians and replaced the former

42

 
 
 
formula with fixed annual updates, and established a quality payment incentive program, also referred to as the Quality Payment Program. This program
provides  clinicians  with  two  ways  to  participate,  including  through  the  Advanced  Alternative  Payment  Models,  or  APMs,  and  the  Merit-based  Incentive
Payment System, or MIPS. In November 2019, CMS issued a final rule finalizing the changes to the Quality Payment Program. At this time, it is unclear how
the introduction of the Quality Payment Program will impact overall physician reimbursement under the Medicare program. Any reduction in reimbursement
from Medicare or other government programs may result in a similar reduction in payments from private payors.

In April 2014, Congress passed the Protecting Access to Medicare Act of 2014 (“PAMA”), which included substantial changes to the way in which
clinical laboratory services are paid under Medicare. Under PAMA, laboratories that receive the majority of their Medicare revenues from payments made
under  the  Medicare  Clinical  Laboratory  Fee  Schedule,  or  the  Physician  Fee  Schedule  are  required  to  report  to  CMS,  beginning  in  2017  and  every  three
years thereafter (or annually for “advanced diagnostic laboratory tests”), private payer payment rates and volumes for their tests. CMS will use this data to
calculate a weighted median payment rate for each test, which will be used to establish revised Medicare reimbursement rates for the tests. Laboratories
that  fail  to  report  the  required  payment  information  may  be  subject  to  substantial  civil  monetary  penalties.  In  January  2020,  CMS  announced  that  data
reporting  for  clinical  diagnostic  laboratory  tests  is  delayed  by  one  year.  Moreover,  the  Coronavirus  Aid,  Relief,  and  Economic  Security  (“CARES”)  Act,
enacted  in  March  2020,  further  delays  the  reporting  period  by  an  additional  year.  Therefore,  data  that  was  originally  supposed  to  be  reported  between
January 1, 2020 and March 31, 2020 must now be reported between January 1, 2022 and March 31, 2022. Covered laboratories must report data from the
original data collection period of January 1, 2019 through June 30, 2019. Data reporting for these tests will then resume on a three year cycle beginning in
2025. The payment rate applies to laboratory tests furnished by a hospital laboratory if the test is separately paid under the hospital outpatient prospective
payment  system.  It  is  still  too  early  to  predict  the  full  impact  on  reimbursement  for  our  products  in  development.  In  addition,  CMS  updated  the  statutory
phase-in  provisions  such  that,  for  2020,  the  rates  for  clinical  diagnostic  laboratory  tests  may  not  be  reduced  by  more  than  10%  of  the  rates  for  2019.
Pursuant to the CARES Act, the statutory phase-in of payment reductions has been extended through 2024 with a 0% reduction cap for 2021 and a 15%
reduction cap for each of 2022, 2023, and 2024. It is unclear what impact new quality and payment programs, such as MACRA, or new pricing structures,
such as those adopted under PAMA, may have on our business, financial condition, results of operations, or cash flows.

Further, it is possible that additional governmental action is taken to address the COVID-19 pandemic. We also anticipate there will continue to be
proposals by legislators at both the federal and state levels, regulators and private payers to reduce costs while expanding individual healthcare benefits.
Certain  of  these  changes  could  impose  additional  limitations  on  the  prices  we  will  be  able  to  charge  for  our  tests,  the  coverage  of  or  the  amounts  of
reimbursement available for our tests from payers, including commercial payers and government payers.

If we use hazardous materials in a manner that causes injury, we could be liable for resulting damages.

Our  activities  currently  require  the  use  of  hazardous  chemicals  and  biological  material.  We  cannot  eliminate  the  risk  of  an  accidental
environmental release or injury to employees or third parties from the use, storage, handling, or disposal of these materials. In the event of an environmental
release or injury, we could be held liable for any resulting damages, and any liability could exceed our resources or any applicable insurance coverage we
may  have.  Additionally,  we  are  subject  on  an  ongoing  basis  to  federal,  state,  and  local  laws  and  regulations  governing  the  use,  storage,  handling,  and
disposal of these materials and specified waste products. The cost of maintaining compliance with these laws and regulations may become significant and
our failure to comply may result in substantial fines or other consequences, and either could negatively affect our operating results.

The 2017 tax reform law, as modified by 2020 tax legislation, and possible future changes in tax laws or regulations could adversely
affect our business and financial condition.

On  December  22,  2017,  former  President  Trump  signed  into  law  comprehensive  tax  legislation  (the  “Tax  Cuts  and  Jobs  Act”)  that  significantly
revised the Internal Revenue Code of 1986, as amended (the “Code”). Future guidance from the U.S. Internal Revenue Service and other tax authorities with
respect to the Tax Cuts and Jobs Act may affect us, and certain aspects of the Tax Cuts and Jobs Act could be repealed or modified in future legislation. For
example, on March 27, 2020, the CARES Act was enacted, which includes changes to the tax provisions that benefit business entities and makes certain
technical corrections to the Tax Cuts and Jobs Act. On June 29, 2020, California Assembly Bill 85 (AB 85) was signed into law, which suspends the use of
California net operating losses and limits the use of California research tax credits for tax years beginning in 2020 and before 2023. On December 27, 2020,
the  Consolidated  Appropriations  Act,  a  coronavirus  relief  package  that  extended  and  expanded  various  tax  provisions,  was  signed  into  law.  Changes  in
corporate  tax  rates,  the  realization  of  net  deferred  tax  assets  relating  to  our  U.S.  operations,  the  taxation  of  foreign  earnings,  and  the  deductibility  of
expenses under the Tax Cuts and Jobs Act, the CARES Act, or future tax reform legislation could have a material impact on the value of our deferred tax
assets,  could  result  in  significant  one-time  charges  in  the  current  or  future  taxable  years,  and  could  increase  our  future  U.S.  tax  expense.  The  foregoing
items,  as  well  as  any  other  future  changes  in  tax  laws,  could  have  a  material  adverse  effect  on  our  business,  cash  flow,  financial  condition,  or  results  of
operations. In addition, it is uncertain if and to what extent various states will conform to the Tax Cuts and Jobs Act, the CARES Act, or any newly enacted
federal tax legislation.

Our effective tax rate may fluctuate, and we may incur obligations in tax jurisdictions in excess of accrued amounts.

We are subject to taxation in numerous U.S. states and territories, as well as various non-U.S. jurisdictions. As a result, our effective tax rate is
derived from a combination of applicable tax rates in the various jurisdictions that we operate. In preparing our financial statements, we estimate the amount
of tax that will become payable in each jurisdiction. Nevertheless, our effective tax rate

43

may be different than experienced in the past due to numerous factors, including passage of the Tax Cuts and Jobs Act and the CARES Act, changes in the
mix of our profitability from state to state, the results of examinations and audits of our tax filings, our inability to secure or sustain acceptable agreements
with tax authorities, changes in accounting for income taxes and changes in tax laws. Any of these factors could cause us to experience an effective tax rate
significantly  different  from  previous  periods  or  our  current  expectations  and  may  result  in  tax  obligations  in  excess  of  amounts  accrued  in  our  financial
statements.

The exit of the U.K. from the EU, commonly referred to as “Brexit” could lead to regulatory divergence and require us to incur additional
expenses in order to develop, manufacture, and commercialize our products and services.

Following the result of a referendum in 2016, the U.K. left the EU on January 31, 2020, commonly referred to as “Brexit.” Pursuant to the formal
withdrawal arrangements agreed between the U.K. and the EU, the U.K. was subject to a transition period until December 31, 2020 (the “Transition Period”),
during which EU rules continued to apply. A deal that outlines the future trading relationship between the U.K. and the EU was agreed in December 2020
and has been approved by each EU member state and the U.K.

While the deal provides for, in most cases, tariff-free trade of goods between the U.K. and the EU, there are additional non-tariff costs to such
trade which did not exist prior to the end of the Transition Period. For example, a UKCA mark will be required to sell medical devices to customers in Great
Britain, rather than a CE mark.

Should  the  U.K.  or  Great  Britain  further  diverge  from  the  EU  from  a  regulatory  perspective  (for  example,  by  not  mirroring  the  provisions  of  the
IVDR), tariffs could be put into place in the future. We could therefore, both now and in the future, face significant additional expenses (when compared to
the position prior to the end of the Transition Period) to operate our business, which could significantly and materially harm or delay our ability to generate
revenues  or  achieve  profitability  of  our  business.  Any  further  changes  in  international  trade,  tariff  and  import/export  regulations  as  a  result  of  Brexit  or
otherwise may impose unexpected duty costs or other non-tariff barriers on us. These developments, or the perception that any of them could occur, may
significantly reduce global trade and, in particular, trade between the impacted nations and the U.K. It is also possible that Brexit may negatively affect our
ability to attract and retain employees, particularly those from the EU.

Intellectual Property Risks

Litigation or other proceedings or third-party claims of intellectual property infringement, misappropriation or other violations may
require us to spend significant time and money, and could in the future prevent us from selling our tests or impact our stock price, any
of which could have a material adverse effect.

Our commercial success will depend in part on our avoiding infringement of patents and infringement, misappropriation or other violations of other
proprietary rights of third parties, including for example the intellectual property of competitors. There is extensive intellectual property litigation involving the
biotechnology and pharmaceutical industries and genetic sequencing technology. Our activities may be subject to claims that we infringe or otherwise violate
patents owned or controlled by third parties. Numerous U.S. and foreign patents and pending patent applications exist in the genetic testing market and are
owned by third parties. We cannot assure you that our operations do not, or will not in the future, infringe existing or future patents. For example, we are
aware of several third-party issued U.S. patents and pending patent applications with claims relating to genetic sequencing technology and methodology that
may be asserted against us and may be construed to encompass our products and services, including ACE ImmunoID and ImmunoID NeXT technology. In
order to avoid infringing these third-party patents, we may find it necessary to or prudent to initiate invalidity proceedings against such patents or to obtain
licenses  from  such  third-party  intellectual  property  holders.  If  we  are  not  able  to  invalidate  such  patents  or  obtain  or  maintain  a  license  on  commercially
reasonable  terms  and  such  third  parties  assert  infringement  claims  against  us,  we  may  be  prevented  from  exploiting  our  technology  and  our  business,
financial  condition,  results  of  operations,  and  prospects  may  be  materially  and  adversely  affected.  We  may  also  be  unaware  of  patents  that  a  third  party,
including for example a competitor in the genetic testing market, might assert are infringed by our business. There may also be patent applications that, if
issued as patents, could be asserted against us. Patent applications in the U.S. and elsewhere are typically published approximately 18 months after the
earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Certain U.S. patent applications that
will not be filed outside the U.S. can remain confidential until patents issue. Therefore, patent applications covering our products, services, or technologies
could  have  been  filed  by  third  parties  without  our  knowledge.  Additionally,  pending  patent  applications  that  have  been  published  can,  subject  to  certain
limitations, be later amended in a manner that could cover our products, services, technologies, and their use. The scope of a patent claim is determined by
an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history and can involve other factors such as expert opinion. Our
interpretation of the relevance or the scope of claims in a patent or a pending application may be incorrect, which may negatively impact our ability to market
our products and services. Further, we may incorrectly determine that our technologies, products, or services are not covered by a third-party patent or may
incorrectly predict whether a third party’s pending patent application will issue with claims of relevant scope. Our determination of the expiration date of any
patent  in  the  U.S.  or  abroad  that  we  consider  relevant  may  be  incorrect,  which  may  negatively  impact  our  ability  to  develop  and  market  our  products  or
services.

Third-party intellectual property right holders may also actively bring infringement or other intellectual property-related claims against us, even if
we have received patent protection for our technologies, products, and services. Regardless of the merit of third parties’ claims against us for infringement,
misappropriation  or  violations  of  their  intellectual  property  rights,  such  third  parties  may  seek  and  obtain  injunctive  or  other  equitable  relief,  which  could
effectively  block  our  ability  to  perform  our  tests.  Further,  if  a  patent  infringement  suit  were  brought  against  us,  we  could  be  forced  to  stop  or  delay  our
development or sales of any tests or other activities that are the subject of such suit. Defense of these claims, even if such claims are resolved in our favor,
could cause us to incur

44

substantial expenses and be a substantial diversion of our employee resources even if we are ultimately successful. Any adverse ruling or perception of an
adverse  ruling  in  defending  ourselves  could  have  a  material  adverse  impact  on  our  cash  position  and  stock  price.  Such  litigation  or  proceedings  could
substantially  increase  our  operating  losses  and  reduce  the  resources  available  for  development  activities  or  any  future  sales,  marketing,  or  distribution
activities. We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able
to  sustain  the  costs  of  such  litigation  or  proceedings  more  effectively  than  we  can  because  of  their  greater  financial  resources  and  more  mature  and
developed intellectual property portfolios.

As we continue to commercialize our tests in their current or an updated form, launch different and expanded tests and enter new markets, other
competitors might claim that our tests infringe, misappropriate or violate their intellectual property rights as part of business strategies designed to impede
our successful commercialization and entry into new markets. If such a suit were brought, regardless of merit, there is no assurance that a court would find in
our  favor  on  questions  of  infringement,  validity,  enforceability,  or  priority.  Even  if  we  are  successful  in  defending  against  such  a  suit,  we  could  incur
substantial  costs  and  diversion  of  the  attention  of  our  management  and  technical  personnel  in  defending  ourselves  against  such  claims.  A  court  of
competent  jurisdiction  could  hold  that  third-party  patents  asserted  against  us  are  valid,  enforceable,  and  infringed,  which  could  materially  and  adversely
affect our ability to commercialize any products, services or technologies we may develop and any other technologies covered by the asserted third-party
patents and any adverse ruling or perception of an adverse ruling in defending ourselves could have a material adverse impact on our cash position and
stock  price.  If  we  are  found  to  infringe,  misappropriate  or  otherwise  violate  a  third  party’s  intellectual  property  rights,  and  we  are  unsuccessful  in
demonstrating that such rights are invalid or unenforceable, we may be required to pay substantial damages, including treble damages and attorneys’ fees
for willful infringement; obtain one or more licenses from third parties in order to continue developing and marketing our products and technology, which may
not be available on commercially reasonable terms (if at all) or may be non-exclusive, thereby giving our competitors and other third parties access to the
same technologies licensed to us; pay substantial royalties and other fees; and redesign any infringing tests or other activities, which may be impossible or
require substantial time and monetary expenditure, or be prohibited from commercializing certain tests, all of which could have a material adverse effect on
our business, financial condition, results of operations, and prospects.

Where we collaborate with third parties in the development of technology, our collaborators may not properly maintain or defend our intellectual
property  rights  or  may  use  our  proprietary  information  in  such  a  way  as  to  invite  litigation  that  could  jeopardize  or  invalidate  our  intellectual  property  or
proprietary  information.  Further,  collaborators  may  infringe  the  intellectual  property  rights  of  third  parties,  which  may  expose  us  to  litigation  and  potential
liability. Also, we may be obligated under our agreements with our collaborators, licensors, suppliers and others to indemnify and hold them harmless for
damages arising from intellectual property infringement by us.

If we cannot license rights to use technologies on reasonable terms, we may not be able to commercialize new products in the future.

In the future, we may identify additional third-party intellectual property we may need to license in order to engage in our business, including to
develop or commercialize new products or services. However, such licenses may not be available on acceptable terms, or at all. Even if such licenses are
available, we may be required to pay the licensor substantial royalties based on sales of our products and services. Such royalties are a component of the
cost of our products or services and may affect the margins on our products and services. In addition, such licenses may be nonexclusive, which could give
our competitors access to the same intellectual property licensed to us. If we are unable to enter into the necessary licenses on acceptable terms or at all, if
any necessary licenses are subsequently terminated, if our licensors fail to abide by the terms of the licenses, if our licensors fail to prevent infringement by
third parties, or if the licensed patents or other rights are found to be invalid or unenforceable, our business, financial condition, results of operations, and
prospects could be materially and adversely affected.

If  licenses  to  third-party  intellectual  property  rights  are  or  become  required  for  us  to  engage  in  our  business,  the  rights  may  be  non-exclusive,
which could give our competitors access to the same technology or intellectual property rights licensed to us. Moreover, we could encounter delays in the
introduction  of  tests  while  we  attempt  to  develop  alternatives.  Defense  of  any  lawsuit  or  failure  to  obtain  any  of  these  licenses  on  favorable  terms  could
prevent us from commercializing tests, which could materially affect our ability to grow and thus adversely affect our business and financial condition.

Developments or uncertainty in the patent statute, patent case law or U.S. Patent and Trademark Office (“USPTO”), rules and
regulations may impact the validity, scope or enforceability of our patent rights, thereby impairing our ability to protect our products.

Our patent rights, their associated costs, and the enforcement or defense of such patent rights may be affected by developments or uncertainty in

the patent statute, patent case law or USPTO rules and regulations.

There are a number of recent changes to the patent laws that may have a significant impact on our ability to protect our technology and enforce
our  intellectual  property  rights.  For  example,  the  Leahy-Smith  America  Invents  Act  (the  “AIA”)  enacted  within  the  last  several  years  involves  significant
changes in patent legislation. These include provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. As an
example, assuming that other requirements for patentability are met, prior to March 2013, in the U.S., the first to invent the claimed invention was entitled to
the  patent,  while  outside  the  U.S.,  the  first  to  file  a  patent  application  was  entitled  to  the  patent.  On  or  after  March  16,  2013,  under  the  AIA,  the  U.S.
transitioned to a first inventor to file system in which, assuming that other requirements for patentability are met, means that the party that is first to file in the
U.S. generally is awarded the patent rights, regardless of whether such party invented the claimed invention first.

45

The  AIA  also  includes  a  number  of  significant  changes  that  affect  the  way  patent  applications  will  be  prosecuted  and  also  may  affect  patent
litigation. These include allowing third party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of
a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. Because of a lower
evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. federal courts necessary to invalidate a patent claim, a third party
could  potentially  provide  evidence  in  a  USPTO  proceeding  sufficient  for  the  USPTO  to  hold  a  claim  invalid  even  though  the  same  evidence  would  be
insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate
our  patent  claims  that  would  not  have  been  invalidated  if  first  challenged  by  the  third  party  as  a  defendant  in  a  district  court  action.  The  AIA  and  its
implementation  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  our  patent  applications  and  the  enforcement  or  defense  of  our
issued patents, all of which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

Further, the standards applied by the USPTO and foreign patent offices in granting patents are not always applied uniformly or predictably. For
example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in biotechnology patents. As such, we do
not  know  the  degree  of  future  protection  that  we  will  have  on  our  technologies,  products,  and  services.  While  we  will  endeavor  to  try  to  protect  our
technologies, products, and services with intellectual property rights such as patents, as appropriate, the process of obtaining patents is time-consuming,
expensive, and sometimes unpredictable.

In  addition,  the  patent  position  of  companies  engaged  in  the  development  and  commercialization  of  diagnostic  tests  is  particularly  uncertain.
Various  courts,  including  the  Supreme  Court  have  rendered  decisions  that  affect  the  scope  of  patentability  of  certain  inventions  or  discoveries  relating  to
certain  diagnostic  tests  and  related  methods.  These  decisions  state,  among  other  things,  that  a  patent  claim  that  recites  an  abstract  idea,  natural
phenomenon or law of nature (for example, the relationship between particular genetic variants and cancer) are not themselves patentable. Precisely what
constitutes a law of nature or abstract idea is uncertain, and it is possible that certain aspects of genetic diagnostics tests would be considered natural laws.
Accordingly, the evolving case law in the U.S. may adversely affect our ability to obtain patents and may facilitate third-party challenges to any owned or
licensed  patents.  The  laws  of  some  foreign  countries  do  not  protect  intellectual  property  rights  to  the  same  extent  as  the  laws  of  the  U.S.,  and  we  may
encounter difficulties in protecting and defending such rights in foreign jurisdictions. The legal systems of many other countries do not favor the enforcement
of patents and other intellectual property protection, particularly those relating to biotechnology, which could make it difficult for us to stop the infringement of
our  patents  in  such  countries.  Proceedings  to  enforce  our  patent  rights  in  foreign  jurisdictions  could  result  in  substantial  cost  and  divert  our  efforts  and
attention from other aspects of our business.

Patent terms may be inadequate to protect our competitive position for an adequate amount of time.

Patents have a limited lifespan. In the U.S., the natural expiration of a patent is generally 20 years after its first effective non-provisional filing date.
Although  various  extensions  may  be  available,  the  life  of  a  patent,  and  the  protection  it  affords,  is  limited.  Even  if  patents  covering  our  technologies,
products, and services are obtained, once the patent life has expired, we may be open to competition from competitive products. Our issued patents will
expire on dates ranging from 2033 to 2038, subject to any patent extensions that may be available for such patents. If patents are issued on our pending
patent  applications,  the  resulting  patents  are  projected  to  expire  on  dates  ranging  from  2033  to  2040.  In  addition,  although  upon  issuance  in  the  U.S.  a
patent’s life can be increased based on certain delays caused by the USPTO, this increase can be reduced or eliminated based on certain delays caused by
the  patent  applicant  during  patent  prosecution.  If  we  do  not  have  sufficient  patent  life  to  protect  our  technologies,  products  and  services,  our  competitive
position, business, financial condition, results of operations, and prospects will be adversely affected.

If we are not able to obtain and enforce patent protection for any products we develop and for our technologies, or if the scope of
patent protection obtained is not sufficiently broad, our competitors and other third parties could develop and commercialize products
and technology similar or identical to ours, and our ability to successfully commercialize our products, services, and technologies may
be adversely affected.

We have applied, and we intend to continue applying, for patents covering such aspects of our technologies as we deem appropriate. However,
the patent process is expensive, time consuming and complex, and we may not be able to apply for patents on certain aspects of our services, products, and
other technologies in a timely fashion, at a reasonable cost, in all jurisdictions or at all, and any potential patent coverage we obtain may not be sufficient to
prevent substantial competition.

Moreover,  the  patent  position  of  biotechnology  companies  can  be  highly  uncertain  because  it  involves  complex  legal  and  factual  questions  for
which important legal principles remain unresolved. No consistent policy regarding the breadth of claims allowed in such companies’ patents has emerged to
date  in  the  U.S.  or  elsewhere.  Courts  frequently  render  opinions  in  the  biotechnology  field  that  may  affect  the  patentability  of  certain  inventions  or
discoveries, including opinions that may affect the patentability of methods for analyzing nucleic acid sequences.

Others may independently develop similar or alternative technologies or design around technologies for which we may not be able to obtain patent
protection.  In  addition,  any  patent  applications  we  file  may  be  challenged  and  may  not  result  in  issued  patents  or  may  be  invalidated,  rendered
unenforceable  or  narrowed  in  scope  after  they  are  issued,  and  there  is  no  guarantee  any  of  our  issued  patents  include  or  will  include  claims  that  are
sufficiently broad to cover our products, services and other technologies or to provide meaningful protection from our competitors. Consequently, we do not
know  whether  any  of  our  platform  advances,  products,  services,  and  other  technologies  will  be  protectable  or  remain  protected  by  valid  and  enforceable
patents. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-
infringing manner.

46

Even if they are unchallenged, our patents and patent applications may not adequately protect our intellectual property, provide exclusivity for our
technologies,  products,  and  services,  or  prevent  others  from  designing  around  our  claims.  Any  finding  that  our  patents  or  applications  are  invalid,
unpatentable, or unenforceable could harm our ability to prevent others from practicing the related technology, and a finding that others have inventorship or
ownership  rights  to  our  patents  and  applications  could  require  us  to  obtain  certain  rights  to  practice  related  technologies,  which  may  not  be  available  on
favorable terms, if at all. If we initiate lawsuits to protect or enforce our patents, or litigate against third-party claims, which would be expensive, and, if we
lose, we may lose some of our intellectual property rights. Furthermore, these lawsuits may divert the attention of our management and technical personnel.
Any of the foregoing could have a material adverse effect on our competitive position, business, financial condition, results of operations, and prospects.

Once  granted,  patents  may  remain  open  to  opposition,  interference,  re-examination,  post-grant  review,  inter  partes  review,  nullification  or
derivation action in court or before patent offices or similar proceedings for a given period after allowance or grant, during which time third parties can raise
objections  against  such  initial  grant.  In  the  course  of  such  proceedings,  which  may  continue  for  a  protracted  period  of  time,  the  patent  owner  may  be
compelled  to  limit  the  scope  of  the  granted  claims  thus  attacked,  or  may  lose  the  granted  claims  altogether.  An  adverse  determination  in  any  such
proceeding  or  litigation  could  reduce  the  scope  of,  or  invalidate,  our  patent  rights,  allow  third  parties  to  commercialize  our  technology  or  products  and
compete directly with us, without payment to us, or result in our inability to commercialize our products, services and technologies without infringing third-
party  patent  rights.  Such  proceedings  also  may  result  in  substantial  cost  and  require  significant  time  from  our  scientists  and  management,  even  if  the
eventual outcome is favorable to us. If the breadth or strength of protection provided by our patents and patent applications is threatened, regardless of the
outcome, it could dissuade companies from collaborating with us to license, develop or commercialize current or future products or technologies. In addition,
there can be no assurance that:

•

•

•

•

•

•

•

•

•

•

others will not or may not be able to make, use, offer to sell, or sell tests that are the same as or similar to our products or services but that
are not covered by the claims of the patents that we own or license;

we  or  our  future  licensors  or  collaborators  are  the  first  to  make  the  inventions  covered  by  each  of  our  issued  patents  and  pending  patent
applications that we own or license;

we or our future licensors or collaborators are the first to file patent applications covering certain aspects of our inventions;

others will not independently develop similar or alternative technologies or duplicate any of our technologies without infringing our intellectual
property rights;

a third party may not challenge our patents and, if challenged, a court would hold that our patents are valid, enforceable, and infringed;

any issued patents that we own or may license will provide us with any competitive advantages, or will not be challenged by third parties;

we may develop or in-license additional proprietary technologies that are patentable;

pending patent applications that we own or may license will lead to issued patents;

the patents of others will not have a material or adverse effect on our business, financial condition, results of operations, and prospects; and

our competitors do not conduct research and development activities in countries where we do not have enforceable patent rights and then
use the information learned from such activities to develop competitive products for sale in our major commercial markets.

The issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability. Some of our patents or patent applications may
be  challenged  at  a  future  point  in  time  in  opposition,  derivation,  reexamination,  inter  partes  review,  post-grant  review,  or  interference  proceedings.  Any
successful opposition to these patents or any other patents owned by or, if applicable in the future, licensed to us could deprive us of rights necessary for the
practice  of  our  technologies  or  the  successful  commercialization  of  any  products  or  technologies  that  we  may  develop,  which  could  lead  to  increased
competition to our business and harm our business. Since patent applications in the U.S. and most other countries are confidential for a period of time after
filing, we cannot be certain that we or our licensors were the first to file any patent application related to our technologies, products, or services. Furthermore,
an interference proceeding can be provoked by a third party or instituted by the USPTO to determine who was the first to invent any of the subject matter
covered by the patent claims of our applications for any application with an effective filing date before March 16, 2013.

Where we obtain licenses from or collaborate with third parties, in some circumstances, we may not have the right to control the preparation, filing,
and  prosecution  of  patent  applications,  or  to  maintain  the  patents,  covering  technology  that  we  license  from  third  parties.  We  may  also  require  the
cooperation of our licensors and collaborators to enforce any licensed patent rights, and such cooperation may not be provided. Therefore, these patents
and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. Moreover, if we do obtain necessary
licenses, we will likely have obligations under those licenses, and any failure to satisfy those obligations could give our licensor the right to terminate the
license. Termination of a necessary license could have a material adverse impact on our business.

47

 
 
 
 
 
 
 
 
 
 
It is also possible that we fail to file patent applications covering inventions made in the course of development and commercialization activities
before  a  competitor  or  another  third  party  files  a  patent  application  covering,  or  publishes  information  disclosing,  a  similar,  independently-developed
invention. Such competitor’s patent application may pose obstacles to our ability to obtain or limit the scope of patent protection we may obtain. Although we
enter into non-disclosure and confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development
output,  such as our employees, collaborators, contract  manufacturers,  consultants,  advisors,  and  other  third  parties,  any  of  these  parties  may  breach  the
agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. In addition, publications of
discoveries  in  the  scientific  literature  often  lag behind  the  actual  discoveries,  and  patent  applications  in  the  U.S.  and  other  jurisdictions  are  typically  not
published  until  18  months  after  filing,  or  in  some  cases  not  at  all.  Therefore,  we  cannot  be  certain  that  we  or  our  licensors  were  the  first  to  make  the
inventions  claimed  in  our  owned  or  licensed  patents  or  pending  patent  applications, or  were  the  first  to  file  for  patent  protection  of  such  inventions.  To
determine the priority of these inventions, we may have to participate in interference proceedings, derivation proceedings, inter partes review proceedings, or
other  post-grant  proceedings  declared  by  the  USPTO  that  could  result  in  substantial  cost  to  us.  The  outcome  of  such  proceedings  is  uncertain.  No
assurance can be given that other patent applications will not have priority over our patent applications. In addition, changes to the patent laws of the U.S.
allow for various post-grant opposition proceedings, such as inter partes review proceedings, that have not been extensively tested, and their outcome is
therefore uncertain. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing
party.  Our  business  could  be  harmed  if  the  prevailing  party  does  not  offer  us  a  license  on  commercially  reasonable  terms  or  at  all,  or  if  a  non-exclusive
license  is  offered  and  our  competitors  gain  access  to  the  same  technology.  Furthermore,  if  third  parties  bring  these  proceedings  against  our  patents,  we
could experience significant costs and management distraction.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time
consuming, and unsuccessful.

Competitors  may  also  infringe  our  patents  or  the  patents  of  our  licensing  partners.  In  addition,  our  patents  or  the  patents  of  our  licensors  may
become  involved  in  inventorship,  priority,  or  validity  disputes.  To  counter  or  defend  against  such  claims  can  be  expensive  and  time  consuming.  In  an
infringement  proceeding,  a  court  may  refuse  to  stop  the  other  party  from  using  the  technology  at  issue  on  the  grounds  that  our  owned  and  in-licensed
patents  do  not  cover  the  technology  in  question.  Further  in  such  proceedings,  the  defendant  could  counterclaim  that  our  asserted  patent  covering  our
product is invalid or unenforceable, and the court may agree that our asserted patent is invalid or unenforceable. In patent litigation in the U.S., defendant
counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several
statutory  requirements,  including  lack  of  novelty,  obviousness  or  non-enablement.  Grounds  for  an  unenforceability  assertion  could  be  an  allegation  that
someone connected with the prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution.
Third  parties  may  also  raise  similar  claims  before  administrative  bodies  in  the  U.S.  or  abroad,  even  outside  the  context  of  litigation.  Such  mechanisms
include  re-examination,  post  grant  review,  inter  partes  review,  and  equivalent  proceedings  in  foreign  jurisdictions  (e.g.,  opposition  proceedings).  Such
proceedings  could  result  in  revocation  or  amendment  to  our  patents  in  such  a  way  that  they  no  longer  cover  our  product.  The  outcome  following  legal
assertions  of  invalidity  and  unenforceability  is  unpredictable.  With  respect  to  the  validity  question,  for  example,  we  cannot  be  certain  that  there  is  no
invalidating prior art, of which we and the patent examiner were unaware during prosecution. An adverse result in any litigation or other proceeding could put
one or more of our owned or in-licensed patents at risk of being invalidated or interpreted narrowly. Such a loss of patent protection could have a material
adverse  impact  on  our  business.  Furthermore,  because  of  the  substantial  amount  of  discovery  required  in  connection  with  intellectual  property  litigation,
there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses
and could distract our personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions, or
other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse
effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available
for development activities or any future sales, marketing, or distribution activities. We may not have sufficient financial or other resources to conduct such
litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can
because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation and
continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

If we are unable to protect the confidentiality of our trade secrets and know-how, our business and competitive position would be
harmed.

We seek protection for certain aspects of our technologies, products, and services through the filing of patents, registration of copyrights, and use
of non-disclosure agreements. In addition, we also expect to rely on trade secrets and proprietary know-how protection for our confidential and proprietary
information, and we have taken security measures to protect this information. These measures, however, may not provide adequate protection for our trade
secrets, know-how, or other confidential information. Among other things, we seek to protect our trade secrets, know-how, and confidential information by
entering into confidentiality agreements with parties who have access to them, such as our employees, collaborators, contract manufacturers, consultants,
advisors, and other third parties. We cannot guarantee that we have entered into such agreements with each party that may have or have had access to our
trade  secrets  or  proprietary  technology  and  processes.  Moreover,  there  can  be  no  assurance  that  any  confidentiality  agreements  that  we  have  with  our
employees, consultants, or other third parties will provide meaningful protection for our trade secrets, know-how,

48

and confidential information or will provide adequate remedies in the event of unauthorized use or disclosure of such information. Despite these efforts, any
of  these  parties  may  breach  the  agreements  and  disclose  our  proprietary  information,  including  our  trade  secrets,  and  we  may  not  be  able  to  obtain
adequate remedies for such breaches. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we have taken to
protect  our  proprietary  technologies  will  be  effective.  Accordingly,  there  also  can  be  no  assurance  that  our  trade  secrets  or  know-how  will  not  otherwise
become known or be independently developed by competitors.

Enforcing  a  claim  that  a  party  illegally  disclosed  or  misappropriated  a  trade  secret  can  be  difficult,  expensive,  and  time-consuming,  and  the
outcome is unpredictable. In addition, trade secrets may be independently developed by others in a manner that could prevent legal recourse by us. If any of
our confidential or proprietary information, such as our trade secrets, were to be disclosed or misappropriated, or if any such information was independently
developed by a competitor, our competitive position would be materially and adversely harmed.

Trade secrets and know-how can be difficult to protect as trade secrets and know-how will over time be disseminated within the industry through
independent development, the publication of journal articles, and the movement of personnel skilled in the art from company to company or academic to
industry scientific positions. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would
have no right to prevent such competitor from using that technology or information to compete with us, which could harm our competitive position. Because
from time to time we expect to rely on third parties in the development, manufacture and distribution of our products and provision of our services, we must,
at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable,
material transfer agreements, license agreements, collaboration agreements, supply agreements, consulting agreements, or other similar agreements with
our  advisors,  employees,  collaborators,  licensors,  suppliers,  third-party  contractors,  and  consultants  prior  to  beginning  research  or  disclosing  proprietary
information.  These  agreements  typically  limit  the  rights  of  the  third  parties  to  use  or  disclose  our  confidential  information,  including  our  trade  secrets  and
know-how. Despite the contractual provisions employed when working with third parties, the need to share trade secrets, know-how, and other confidential
information increases the risk that such trade secrets and know-how become known by our competitors, are inadvertently incorporated into the technology of
others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a
competitor’s discovery of our trade secrets or know-how, or other unauthorized use or disclosure would impair our competitive position and may have an
adverse effect on our business and results of operations.

In  addition,  these  agreements  typically  restrict  the  ability  of  our  advisors,  employees,  collaborators,  licensors,  suppliers,  third-party  contractors,
and consultants to publish data potentially relating to our trade secrets or know-how, although our agreements may contain certain limited publication rights.
Despite our efforts to protect our trade secrets and know-how, our competitors may discover our trade secrets or know-how, either through breach of our
agreements with third parties, independent development, or publication of information by any of our third-party collaborators. A competitor’s discovery of our
trade secrets or know-how would impair our competitive position and have a material adverse impact on our business.

We may not be able to enforce our intellectual property rights throughout the world.

Filing, prosecuting, maintaining, defending, and enforcing patents on our products, services, and technologies in all countries throughout the world
would  be  prohibitively  expensive,  and  our  intellectual  property  rights  in  some  countries  outside  the  U.S.  can  be  less  extensive  than  those  in  the  U.S.
Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export
otherwise infringing products to territories where we have patent protection or licenses but enforcement is not as strong as that in the U.S. These products
may compete with our products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. In
addition,  the  laws  of  some  foreign  countries  do  not  protect  proprietary  rights  to  the  same  extent  as  the  laws  of  the  U.S.,  and  many  companies  have
encountered significant challenges in establishing and enforcing their proprietary rights outside of the U.S. These challenges can be caused by the absence
or inconsistency of the application of rules and methods for the establishment and enforcement of intellectual property rights outside of the U.S. In addition,
the  legal  systems  of  some  countries,  particularly  developing  countries,  do  not  favor  the  enforcement  of  patents  and  other  intellectual  property  protection,
especially those relating to healthcare. This could make it difficult for us to stop the infringement of our patents, if obtained, or the misappropriation of our
other  intellectual  property  rights.  For  example,  many  foreign  countries,  including  EU  countries,  India,  Japan,  and  China,  have  compulsory  licensing  laws
under  which  a  patent  owner  may  be  compelled  under  specified  circumstances  to  grant  licenses  to  third  parties.  In  addition,  many  countries  limit  the
enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or
no benefit given that we may have limited remedies available if patents are infringed or if we are compelled to grant a license to a third party, which could
materially diminish the value of those patents and limit our potential revenue opportunities. Furthermore, patent protection must ultimately be sought on a
country-by-country  basis,  which  is  an  expensive  and  time-consuming  process  with  uncertain  outcomes.  Accordingly,  we  may  choose  not  to  seek  patent
protection in certain countries, and we will not have the benefit of patent protection in such countries.

Proceedings  to  enforce  our  patent  rights  in  foreign  jurisdictions  could  result  in  substantial  costs  and  divert  our  efforts  and  attention  from  other
aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the
law and legal decisions by courts in the U.S. and foreign countries may affect our ability to obtain adequate protection for our products, services and other
technologies and the enforcement of intellectual property. Any of the foregoing could have a material adverse effect on our competitive position, business,
financial condition, results of operations, and prospects.

49

Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and
other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-
compliance with these requirements.

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and
other  provisions  during  the  patent  application  and  prosecution  process.  Periodic  maintenance  fees,  renewal  fees,  annuity  fees,  and  various  other
governmental fees on patents and/or applications will be due to be paid to the USPTO and various other governmental patent agencies outside of the U.S. in
several stages over the lifetime of the patents and/or applications. We employ reputable professionals and rely on such third parties to help us comply with
these  requirements  and  effect  payment  of  these  fees  with  respect  to  the  patents  and  patent  applications  that  we  own.  Noncompliance  events  that  could
result  in  abandonment  or  lapse  of  a  patent  or  patent  application  include  failure  to  respond  to  official  communications  within  prescribed  time  limits,  non-
payment of fees and failure to properly legalize and submit formal documents. In many cases, an inadvertent lapse can be cured by payment of a late fee or
by  other  means  in  accordance  with  the  applicable  rules.  However,  there  are  situations  in  which  noncompliance  can  result  in  abandonment  or  lapse  of  a
patent  or  patent  application,  resulting  in  loss  of  patent  rights  in  the  relevant  jurisdiction.  In  such  an  event,  competitors  might  be  able  to  enter  the  market
earlier  than  would  otherwise  have  been  the  case,  which  could  have  a  material  adverse  effect  on  our  competitive  position,  business,  financial  condition,
results of operations, and prospects.

Third parties may assert that our employees or consultants have wrongfully used or disclosed confidential information or
misappropriated trade secrets.

We  employ  individuals  who  were  previously  employed  or  otherwise  engaged  with  universities  or  genetic  testing,  diagnostic  or  other  healthcare

companies, including our competitors or potential competitors.

Although  we  have  policies  to  ensure  that  our  employees  and  consultants  do  not  use  the  proprietary  information  or  know-how  of  others  in  their
work for us, we may be subject to claims that we or our employees or consultants have inadvertently or otherwise used or disclosed intellectual property,
including trade secrets or other proprietary information, of a former employer or other third parties. Further, we may be subject to ownership disputes in the
future arising, for example, from conflicting obligations of consultants or others who are involved in developing our intellectual property. Litigation may be
necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual
property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to
management  and  other  employees.  Such  claims  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of  operations,  and
prospects.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual
property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in
fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the
assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to
determine  the  ownership  of  what  we  regard  as  our  intellectual  property.  Such  claims  could  have  a  material  adverse  effect  on  our  business,  financial
condition, results of operations, and prospects.

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

A portion of the products or technologies licensed, developed, and/or distributed by us incorporate so-called “open source” software and we may
incorporate open source software into other products in the future. Such open source software is generally licensed by its authors or other third parties under
open  source  licenses.  Some  open  source  licenses  contain  requirements  that  we  disclose  source  code  for  modifications  we  make  to  the  open  source
software  and  that  we  license  such  modifications  to  third  parties  at  no  cost.  In  some  circumstances,  distribution  of  our  software  in  connection  with  open
source software could require that we disclose and license some or all of our proprietary code in that software, as well as distribute our products or provide
our  services  that  use  particular  open  source  software  at  no  cost  to  the  user.  We  monitor  our  use  of  open  source  software  in  an  effort  to  avoid  uses  in  a
manner that would require us to disclose or grant licenses under our proprietary source code; however, there can be no assurance that such efforts will be
successful.  Open  source  license  terms  are  often  ambiguous  and  such  use  could  inadvertently  occur.  There  is  little  legal  precedent  governing  the
interpretation  of  many  of  the  terms  of  these  licenses,  and  the  potential  impact  of  these  terms  on  our  business  may  result  in  unanticipated  obligations
regarding  our  products  and  technologies.  Companies  that  incorporate  open  source  software  into  their  products  have,  in  the  past,  faced  claims  seeking
enforcement of open source license provisions and claims asserting ownership of open source software incorporated into their products. If an author or other
third party that distributes such open source software were to allege that we had not complied with the conditions of an open source license, we could incur
significant legal costs defending ourselves against such allegations. In the event such claims were successful, we could be subject to significant damages or
be enjoined from the distribution of our products. In addition, if we combine our proprietary software with open source software in certain ways, under some
open source licenses, we could be required to release the source code of our proprietary software, which could substantially help our competitors develop
products that are similar to or better than ours and otherwise adversely affect our business. These risks could be difficult to eliminate or manage, and, if not
addressed, could have a material adverse effect on our business, financial condition, and results of operations.

50

If we fail to comply with our obligations under license or technology agreements with third parties, we may be required to pay damages
and we could lose license rights that are critical to our business.

We license certain intellectual property that is important to our business, and in the future we may enter into additional agreements that provide us
with licenses to valuable intellectual property or technology. For example, our agreements with third parties, such as Illumina, include certain non-exclusive
license rights that are essential to the operation of our business as it is currently conducted. If we fail to comply with any of the obligations under our license
agreements, we may be required to pay damages and the licensor may have the right to terminate the license. Termination by the licensor would cause us to
lose valuable rights, and could prevent us from selling our products and services, or inhibit our ability to commercialize future products and services. Our
business  would  suffer  if  any  current  or  future  licenses  terminate,  if  the  licensors  fail  to  abide  by  the  terms  of  the  license,  if  the  licensors  fail  to  enforce
licensed patents against infringing third parties, if the licensed patents or other rights are found to be invalid or unenforceable, or if we are unable to enter
into necessary licenses on acceptable terms. In addition, our rights to certain technologies, including those of Illumina, are licensed to us on a non-exclusive
basis. The owners of these non-exclusively licensed technologies are therefore free to license them to third parties, including our competitors, on terms that
may be superior to those offered to us, which could place us at a competitive disadvantage. Moreover, our licensors may own or control intellectual property
that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the
licensor’s rights.

We may be subject to claims challenging the inventorship of our patents and other intellectual property.

We or our licensors may be subject to claims that former employees, collaborators, or other third parties have an interest in our patents, trade
secrets, or other intellectual property as an inventor or co-inventor. For example, we or our licensors may have inventorship disputes arise from conflicting
obligations  of  employees,  consultants,  or  others  who  are  involved  in  developing  our  products,  services,  or  technologies.  Litigation  may  be  necessary  to
defend  against  these  and  other  claims  challenging  inventorship  or  our  licensors’  ownership  of  our  owned  or  in-licensed  patents,  trade  secrets,  or  other
intellectual property. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights, such
as  exclusive  ownership  of,  or  right  to  use,  intellectual  property  that  is  important  to  our  products,  services,  or  technologies.  Even  if  we  are  successful  in
defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees. Any of the foregoing
could have a material adverse effect on our business, financial condition, results of operations, and prospects.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of
interest and our business may be adversely affected.

Our trademarks or trade names may be challenged, infringed, circumvented, or declared generic or determined to be infringing on other marks.
We  may  not  be  able  to  protect  our  rights  to  these  trademarks  and  trade  names  or  may  be  forced  to  stop  using  these  names,  which  we  need  for  name
recognition by potential partners or customers in our markets of interest. During trademark registration proceedings, we may receive rejections. Although we
would be given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in the USPTO 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. If we are
unable to establish brand name recognition based on our trademarks and trade names, we may not be able to compete effectively and our business may be
adversely affected.

Financial and Market Risks and Risks Related to Owning Our Common Stock

Certain of our customers prepay us for a portion of the services that they expect to order from us in the future and we may be required
to refund some or all of those prepayments if a customer cancels its contract with us or reduces the level of services that it expects to
receive.

Certain  of  our  customers  prepay  us  for  a  portion  of  the  services  that  they  expect  to  order  from  us  before  they  place  purchase  orders  and  we
deliver  those  services.  In  some  cases,  this  prepayment  can  be  substantial  and  may  be  paid  months  or  a  year  or  more  in  advance  of  these  customers
providing samples to us and before our delivery of the services to which some or all of the deposit relates. As of December 31, 2020, we had approximately
$21.0 million in customer deposits, including $18.4 million from one customer. However, as of that date, we had $203.3 million of cash and cash equivalents,
and short-term investments. We are generally not required by our contracts to retain these deposits in cash or otherwise and we have generally used these
deposits  to  make  capital  expenditures  and  fund  our  operations.  When  a  customer  that  has  prepaid  us  for  future  services  cancels  its  contract  with  us  or
reduces the level of services that it expects to receive, we are required to repay that customer’s deposit with little or no notice. We may not have the cash or
other available resources to satisfy that repayment obligation. Even if we are able to satisfy the repayment obligation from available resources, we may need
to  seek  additional  sources  of  capital  to  fund  our  operations,  which  funding  may  not  be  available  when  needed  or  on  acceptable  terms.  In  either  of  those
circumstances, our business, financial condition, results of operations, and reputation would be materially and adversely affected. Furthermore, in the future,
customers  may  elect  not  to  prepay  us  for  our  services  in  which  case  we  would  have  to  find  other  sources  of  funding  for  our  capital  expenditures  and
operations, which would be costly relative to the aforementioned cost-free customer deposit funding and which may not be available when needed or on
acceptable terms.

51

Our inability to raise additional capital on acceptable terms in the future may limit our ability to continue to operate our business and
further expand our operations.

We  expect  capital  expenditures  and  operating  expenses  to  increase  over  the  next  several  years  as  we  continue  to  operate  our  business  and
expand our infrastructure, commercial operations, and research and development activities. Additionally, if we decide to grow our business by developing in
vitro diagnostic tests, our capital expenditures and operating expenses would significantly increase. We may seek to raise additional capital through equity
offerings, debt financings, collaborations, or licensing arrangements. Additional funding may not be available to us on acceptable terms, or at all.

The various ways we could raise additional capital carry potential risks. If we raise funds by issuing equity securities, dilution to our stockholders
would result. Any equity securities issued may also provide for rights, preferences, or privileges senior to those of holders of our common stock. In addition,
the issuance of additional equity securities by us, or the possibility of such issuance, may cause the market price of our common stock to decline. If we raise
funds by issuing debt securities, those debt securities would have rights, preferences, and privileges senior to those of holders of our common stock. The
terms  of  debt  securities  issued  or  borrowings  pursuant  to  a  credit  agreement,  if  available,  could  impose  significant  restrictions  on  our  operations.  The
incurrence of additional indebtedness or the issuance of certain equity securities could result in increased fixed payment obligations and could also result in
restrictive  covenants,  such  as  limitations  on  our  ability  to  incur  additional  debt  or  issue  additional  equity,  limitations  on  our  ability  to  acquire  or  license
intellectual  property  rights,  and  other  operating  restrictions  that  could  adversely  affect  our  ability  to  conduct  our  business.  In  the  event  that  we  enter  into
collaborations or licensing arrangements to raise capital, we may be required to accept unfavorable terms. These agreements may require that we relinquish
or  license  to  a  third  party  on  unfavorable  terms  our  rights  to  tests  we  otherwise  would  seek  to  develop  or  commercialize  ourselves,  or  reserve  certain
opportunities for future potential arrangements when we might be able to achieve more favorable terms.

If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of or eliminate one or more research and
development  programs  or  sales  and  marketing  initiatives.  Our  ability  to  raise  additional  capital  may  be  adversely  impacted  by  potential  worsening  global
economic  conditions  and  the  recent  disruption  to  and  volatility  in  the  credit  and  financial  markets  in  the  U.S.  and  worldwide  resulting  from  the  ongoing
COVID-19 pandemic. In addition, we may have to work with a partner on one or more aspects of our tests or market development programs, which could
lower  the  economic  value  of  those  tests  or  programs  to  us.  While  we  believe  our  existing  cash  and  cash  equivalents,  and  short-term  investments  will  be
sufficient to meet our anticipated cash requirements for at least the next 12 months, we cannot assure you that we will generate sufficient revenues from
commercial sales to adequately fund our operating needs or achieve or sustain profitability.

The market price of our common stock may be volatile or may decline steeply or suddenly regardless of our operating performance, we
may not be able to meet investor or analyst expectations, and you may lose all or part of your investment.

The  market  price  of  our  common  stock  may  fluctuate  or  decline  significantly  in  response  to  numerous  factors,  many  of  which  are  beyond  our

control, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated fluctuations in our operating results;

failure to meet or exceed financial estimates and projections of the investment community or that we provide to the public;

issuance of new or updated research reports by securities analysts or changed recommendations for our stock;

competition from existing tests or new tests that may emerge;

announcements  by  us  or  our  competitors  of  significant  acquisitions,  strategic  partnerships,  joint  ventures,  collaborations,  capital
commitments, or by or pertaining to our customers, particularly the VA MVP, as our largest customer;

the timing and amount of our investments in the growth of our business;

actual or anticipated changes in regulatory oversight of our business or issues we may face with regulators;

additions or departures of key management or other personnel;

inability to obtain additional funding;

sales of our common stock by us or our stockholders in the future;

disputes or other developments related to our intellectual property or other matters, including litigation;

the  long-term  macroeconomic  effects  of  the  COVID-19  pandemic,  including  potential  global,  regional  or  national  economic  slowdowns,
recessions, depressions or other economic downturns; and

general economic, industry, and market conditions, including factors unrelated to our operating performance or the operating performance of
our competitors.

52

 
 
 
 
 
 
 
 
 
 
 
 
 
In  addition,  the  stock  market  in  general,  and  the  market  for  life  sciences  companies  in  particular,  has  experienced  extreme  price  and  volume
fluctuations that have often been unrelated or disproportionate to the operating performance of those companies, including very recently in connection with
the ongoing COVID-19 pandemic, which has resulted in depressed stock prices for many companies notwithstanding the lack of a fundamental change in
their underlying business models or prospects. Broad market and industry factors may seriously affect the market price of our common stock, regardless of
our actual operating performance. In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s
securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial
costs and a diversion of our management’s attention and resources.

Moreover, because of these fluctuations, comparing our operating results on a period-to-period basis may not be meaningful. You should not rely
on our past results as an indication of our future performance. This variability and unpredictability could also result in our failing to meet the expectations of
industry or financial analysts or investors for any period. If our revenues or operating results fall below the expectations of analysts or investors or below any
forecasts we may provide to the market, or if the forecasts we provide to the market are below the expectations of analysts or investors, the price of our
common  stock  could  decline  substantially.  Such  a  stock  price  decline  could  occur  even  when  we  have  met  any  previously  publicly  stated  revenues  or
earnings forecasts that we may provide.

Our quarterly results may fluctuate significantly, which could adversely impact the value of our common stock.

Our  quarterly  results  of  operations,  including  our  revenue,  gross  margin,  profitability,  and  cash  flows,  may  vary  significantly  in  the  future,  and
period-to-period comparisons of our operating results may not be meaningful. Accordingly, our quarterly results should not be relied upon as an indication of
future performance. Our quarterly financial results may fluctuate as a result of a variety of factors, many of which are outside of our control. For example, the
VA MVP and other large customers are not obliged to deliver tissue samples or other specimens to us at any particular time or at all. The rate at which we
receive  tissue  samples  or  other  specimens  can  vary  dramatically  from  quarter  to  quarter,  and  is  difficult  or  impossible  for  us  to  accurately  forecast.  Our
receipt and processing of tissue samples and other specimens from our customers leads to our recognition of revenue, and as such the variable rates of
delivery of customer samples will lead to variations in our revenues from quarter to quarter. For example, we often see fluctuations in receipt and processing
of  samples  and  revenues  in  the  fourth  quarter  due,  in  part,  to  the  concentration  of  holidays  in  late  November  and  in  December,  and  some  of  our
biopharmaceutical  customers  have  fiscal  years  ending  in  December,  which  we  believe  may  impact  the  timing  of  samples  or  payments  provided  by  such
customers.  Fluctuations  in  quarterly  results  may  adversely  impact  the  value  of  our  common  stock.  Factors  that  may  cause  fluctuations  in  our  quarterly
financial results include, without limitation, those listed elsewhere in this “Risk Factors” section. We also may face competitive pricing pressures, and we may
not be able to maintain our pricing in the future, which would adversely affect our operating results.

Insiders may exercise significant control over our company and will be able to influence corporate matters.

Acting together, our directors, executive officers and their affiliates, and holders of greater than five percent of our outstanding common stock are
able  to  exercise significant influence over our management  and  affairs  and  matters  requiring  stockholder  approval,  including  the  election  of  directors  and
approval of significant corporate transactions, such as mergers, consolidations or the sale of substantially all of our assets. This concentration of ownership
may have the effect of delaying or preventing a third party from acquiring control of our company and could adversely affect the market price of our common
stock and may not be in the best interests of our other stockholders.

Future sales of shares by existing stockholders, or the perception that such sales could occur, could cause our stock price to decline.

Sales of a substantial number of shares of our common stock into the public market, including sales by members of our management or board of
directors or entities affiliated with such members, could occur at any time. These sales, or the perception in the market that the holders of a large number of
shares intend to sell shares, could reduce the market price of our common stock and could impair our ability to raise capital through the sale of additional
equity or equity-related securities. We are unable to predict the effect that such sales may have on the prevailing market price of our common stock. As of
December 31, 2020, we had 39,105,548 shares of common stock outstanding, all of which shares were eligible as of such date for sale in the public market,
subject in some cases to the volume limitations and manner of sale and other requirements under Rule 144. In addition, upon issuance, shares of common
stock subject to outstanding options under our stock option plans as of December 31, 2020 will become eligible for sale in the public market in the future,
subject to certain legal and contractual limitations. Moreover, certain holders of shares of our common stock have the right to require us to register these
shares under the Securities Act pursuant to an investors’ rights agreement. If our existing stockholders sell substantial amounts of our common stock in the
public market, or if the public perceives that such sales could occur, this could have an adverse effect on the market price of our common stock.

We do not currently intend to pay dividends on our common stock and, consequently, your ability to achieve a return on your
investment will depend on appreciation of the value of our common stock.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain any future earnings to finance the operation and
expansion of our business, and we do not expect to pay any cash dividends on our common stock in the foreseeable future. In addition, our ability to pay
cash  dividends  on  our  capital  stock  is  limited  by  our  credit  agreement  and  may  be  prohibited  or  limited  by  the  terms  of  any  future  debt  financing
arrangement. As a result, any investment returns on our common stock will depend upon increases in the value for our common stock, which are not certain.

53

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive
plans, could result in additional dilution of the percentage ownership of our stockholders and could cause the stock price of our
common stock to decline.

In  the  future,  we  may  sell  common  stock,  rights  to  purchase  common  stock,  convertible  securities,  or  other  equity  securities  in  one  or  more
transactions at prices and in a manner we determine from time to time. We also expect to issue common stock to employees, directors, and consultants
pursuant  to  our  equity  incentive  plans.  If  we  sell  common  stock,  rights  to  purchase  common  stock,  convertible  securities,  or  other  equity  securities  in
subsequent  transactions,  or  common  stock  is  issued  pursuant  to  equity  incentive  plans,  investors  may  be  materially  diluted.  In  addition,  new  investors  in
such subsequent transactions could gain rights, preferences, and privileges senior to those of holders of our common stock.

If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research
about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that equity research analysts publish about us and our
business.  We  do  not  control  these  analysts  or  the  content  and  opinions  included  in  their  reports.  Securities  analysts  may  elect  not  to  provide  research
coverage of our company, and such lack of research coverage may adversely affect the market price of our common stock. The price of our common stock
could also decline if one or more equity research analysts downgrade our common stock or issue other unfavorable commentary or cease publishing reports
about us or our business. If one or more equity research analysts cease coverage of our company, we could lose visibility in the market, which in turn could
cause our stock price to decline.

Holders of our common stock could be adversely affected if we issue preferred stock.

Pursuant  to  our  amended  and  restated  certificate  of  incorporation,  our  board  of  directors  is  authorized  to  issue  up  to  10,000,000  shares  of
preferred stock without any action on the part of our stockholders. Our board of directors will also have the power, without stockholder approval, to set the
terms  of  any  series  of  preferred  stock  that  may  be  issued,  including  voting  rights,  dividend  rights,  preferences  over  our  common  stock  with  respect  to
dividends  or  in  the  event  of  a  dissolution,  liquidation,  or  winding  up,  and  other  terms.  In  the  event  that  we  issue  preferred  stock  in  the  future  that  has
preferences over our common stock with respect to payment of dividends or upon our liquidation, dissolution, or winding up, or if we issue preferred stock
that is convertible into our common stock at greater than a one-to-one ratio, the voting and other rights of the holders of our common stock or the market
price of our common stock could be adversely affected.

Our ability to use net operating losses to offset future taxable income may be subject to limitations.

As  of  December  31,  2020,  we  had  federal  and  state  net  operating  loss  carryforwards  of  approximately  $159.2  million  and  approximately
$112.7 million, respectively. Certain of our federal and state net operating loss carryforwards will begin to expire, if not utilized, beginning in 2031. These net
operating loss carryforwards could expire unused and be unavailable to offset future income tax liabilities. Under the Tax Cuts and Jobs Act, as modified by
the  CARES  Act,  federal  net  operating  losses  incurred  in  tax  years  beginning  in  2018  and  in  future  years  may  be  carried  forward  indefinitely,  but  the
deductibility of such federal net operating losses for tax years beginning after 2020 is limited. It is uncertain if and to what extent various states will conform
to the Tax Cuts and Jobs Act, as modified by the CARES Act. In addition, under Section 382 of the Code, and corresponding provisions of state law, if a
corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year
period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes (including certain tax credits) to
offset its post-change income or taxes may be limited. We have experienced ownership changes in the past, and we may experience ownership changes in
the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control. If an ownership change occurs and our ability
to use our net operating loss carryforwards is materially limited, it could harm our future operating results by effectively increasing our future tax obligations.
In addition, for California income tax purposes, California net operating losses and California research tax credits will be suspended and limited, respectively,
for tax years beginning after 2019 but before 2023.

Delaware law and provisions in our amended and restated certificate of incorporation and amended and restated bylaws could make a
merger, tender offer, or proxy contest difficult, thereby depressing the trading price of our common stock.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could depress the trading price of
our common stock by acting to discourage, delay or prevent a change of control of our company or changes in our management that the stockholders of our
company may deem advantageous. These provisions include the following:

•

•

•

•

establish a classified board of directors so that not all members of our board of directors are elected at one time;

authorize the issuance of “blank check” preferred stock that our board of directors could use to implement a stockholder rights plan;

permit the board of directors to establish the number of directors and fill any vacancies and newly-created directorships;

provide that directors may only be removed for cause;

54

 
 
 
 
•

•

•

•

•

•

require super-majority voting to amend some provisions in our certificate of incorporation and bylaws;

eliminate the ability of our stockholders to call special meetings of stockholders;

prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

provide that the board of directors is expressly authorized to make, alter, or repeal our bylaws;

restrict the forum for certain litigation against us to Delaware; and

establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon
by stockholders at annual stockholder meetings.

Any provision of our amended and restated certificate of incorporation or amended and restated bylaws, or Delaware law that has the effect of
delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and
could also affect the price that some investors are willing to pay for our common stock.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and the federal
district courts of the U.S. will be the exclusive forums for substantially all disputes between us and our stockholders, which could limit
our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for the

following types of actions or proceedings under Delaware statutory or common law:

•

•

•

•

any derivative action or proceeding brought on our behalf;

any action asserting a breach of fiduciary duty;

any  action  asserting  a  claim  against  us  arising  under  the  Delaware  General  Corporation  Law,  our  amended  and  restated  certificate  of
incorporation, or our amended and restated bylaws; and

any action asserting a claim against us that is governed by the internal-affairs doctrine.

This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act. Furthermore, 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  certificate  of  incorporation  further  provides  that  the  federal  district  courts  of  the  U.S.  will  be  the
exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While the Delaware courts have determined that
such  choice  of  forum  provisions  are  facially  valid,  a  stockholder  may  nonetheless  seek  to  bring  a  claim  in  a  venue  other  than  those  designated  in  the
exclusive forum provisions. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provisions of our
amended and restated certificate of incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions,
and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

These exclusive forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or
our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees. If a court were to find
either  exclusive  forum  provision  in  our  amended  and  restated  certificate  of  incorporation  to  be  inapplicable  or  unenforceable  in  an  action,  we  may  incur
further significant additional costs associated with resolving the dispute in other jurisdictions, all of which could seriously harm our business.

The requirements of being a public company consume substantial resources, may result in litigation and may divert management’s
attention.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the
Sarbanes-Oxley  Act  of  2002,  as  amended  (the  “Sarbanes-Oxley  Act”),  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act,  the  listing
requirements of The Nasdaq Global Market and other applicable securities rules and regulations. Complying with these rules and regulations has increased
and  will  increase  our  legal  and  financial  compliance  costs,  make  some  activities  more  difficult,  time-consuming,  or  costly  and  increase  demand  on  our
systems and resources, particularly after we are no longer an “emerging growth company” as defined in the Jumpstart our Business Startups Act of 2012
(the  “JOBS  Act”).  The  Exchange  Act  requires,  among  other  things,  that  we  file  annual,  quarterly,  and  current  reports  with  respect  to  our  business  and
operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control
over financial reporting. We are required to disclose changes made in our internal control and procedures on a quarterly basis. In order to maintain and, if
required,  improve  our  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting  to  meet  this  standard,  significant  resources  and
management oversight may be required. As a result, management’s attention may be diverted

55

 
 
 
 
 
 
 
 
 
 
 
from other business concerns, which could adversely affect our business and operating results. We may be required to hire additional employees or engage
outside consultants to comply with these requirements, which will increase our costs and expenses.

In addition, changing laws, regulations, and standards relating to corporate governance and public disclosure are creating uncertainty for public
companies, increasing legal and financial compliance costs and making some activities more time-consuming. These laws, regulations, and standards are
subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new
guidance  is  provided  by  regulatory  and  governing  bodies.  This  could  result  in  continuing  uncertainty  regarding  compliance  matters  and  higher  costs
necessitated  by  ongoing  revisions  to  disclosure  and  governance  practices.  We  intend  to  invest  resources  to  comply  with  evolving  laws,  regulations,  and
standards,  and  this  investment  will  result  in  increased  general  and  administrative  expenses  and  a  diversion  of  management’s  time  and  attention  from
revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by
regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us
and  our  business  may  be  adversely  affected.  By  disclosing  information  in  this  prospectus  and  in  filings  required  of  a  public  company,  our  business  and
financial condition will become more visible, which we believe may result in threatened or actual litigation, including by competitors and other third parties. If
those claims are successful, our business could be seriously harmed. Even if the claims do not result in litigation or are resolved in our favor, the time and
resources needed to resolve them could divert our management’s resources and seriously harm our business.

As a public company, it may be increasingly expensive for us to obtain director and officer liability insurance and, in the future, we may be required
to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain
qualified members of our board of directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.

In addition, as a result of our disclosure obligations as a public company, we have reduced strategic flexibility as compared to our competitors that
are privately-held companies, and are under pressure to focus on short-term results, which may materially and adversely affect our ability to achieve long-
term profitability.

We are an emerging growth company, and any decision on our part to comply only with certain reduced reporting and disclosure
requirements applicable to emerging growth companies could make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the JOBS Act, and, for as long as we continue to be an emerging growth company, we may
choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to emerging growth companies,
including:

•

•

•

not  being  required  to  have  our  independent  registered  public  accounting  firm  audit  our  internal  control  over  financial  reporting  under
Section 404 of the Sarbanes-Oxley Act;

reduced disclosure obligations regarding executive compensation in our periodic reports and annual report on Form 10-K; and

exemptions from the requirements of holding non-binding advisory votes on executive compensation and stockholder approval of any golden
parachute payments not previously approved.

We could be an emerging growth company for up to five years following the closing of our initial public offering of our common stock. Our status as

an emerging growth company will end as soon as any of the following takes place:

•

•

•

•

the last day of the fiscal year in which we have more than $1.07 billion in annual revenue;

the date we qualify as a “large accelerated filer,” with at least $700 million of equity securities held by non-affiliates;

the date on which we have issued, in any three-year period, more than $1.0 billion in non-convertible debt securities; or

December 31, 2024.

We cannot predict if investors will find our common stock less attractive if we choose to rely on any of the exemptions afforded emerging growth
companies. If some investors find our common stock less attractive because we rely on any of these exemptions, there may be a less active trading market
for our common stock and the market price of our common stock may be more volatile.

Under  the  JOBS  Act,  emerging  growth  companies  can  also  delay  adopting  new  or  revised  accounting  standards  until  such  time  as  those
standards apply to private companies. We have irrevocably elected not to avail ourselves of this accommodation and, therefore, we will be subject to the
same new or revised accounting standards as other public companies that are not emerging growth companies.

Material weaknesses in our internal control over financial reporting may cause us to fail to timely and accurately report our financial
results or result in a material misstatement of our financial statements.

Management  evaluates  our  internal  control  systems,  processes,  and  procedures  for  compliance  with  the  requirements  of  a  smaller  reporting
company under Section 404 of the Sarbanes-Oxley Act of 2002 (“Section 404”). This evaluation includes disclosure of any material weaknesses identified by
our management in our internal control over financial reporting. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control
over  financial  reporting  such  that  there  is  a  reasonable  possibility  that  a  material  misstatement  of  our  annual  or  interim  financial  statements  will  not  be
prevented or detected on a timely basis.

In connection with the preparation of our financial statements for the years ended December 31, 2017 and 2018, management identified a material
weakness in our internal controls due to a lack of sufficient full-time accounting staff with requisite experience and deep technical accounting knowledge to
(i) identify and resolve complex accounting issues under generally accepted accounting principles in the U.S. and (ii) allow for appropriate segregation of
duties.  The  identified  material  weakness  could  result  in  misstatements  to  our  consolidated  financial  statements  that  would  be  material  and  would  not  be
prevented or detected on a timely basis.

We implemented additional procedures to remediate this material weakness, however, we cannot assure you that these or other measures will
prevent future material weaknesses from occurring. Remediation of the material weakness involved hiring a Chief Financial Officer in March 2019 and four
additional  accounting  resources  in  the  second,  third,  and  fourth  quarters  of  2019,  including  two  Certified  Public  Accountants  with  the  specific  technical
accounting and financial reporting experience necessary for a public company. We will continue to assess the adequacy of our accounting personnel and
resources, and will add additional personnel, as well as adjust our resources, as necessary, commensurate with any increase in the size and complexity of
our business.

If we identify future material weaknesses in our internal controls over financial reporting or fail to meet the demands that are placed upon us as a
public company, including the requirements of the Sarbanes-Oxley Act, we may be unable to accurately report our financial results or report them within the
timeframes required by law or stock exchange regulations. Failure to comply with Section 404 could also potentially subject us to sanctions or investigations
by the U.S. Securities and Exchange Commission (the “SEC”) or other regulatory authorities. If additional material weaknesses exist or are discovered in the
future, and we are unable to remediate any such material weakness, our reputation, financial condition, and operating results could suffer.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We have implemented disclosure controls and procedures designed to provide reasonable assurance that information we must disclose in reports
we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized, and reported within
the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures, no matter how well-conceived and
operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple
errors  or  mistakes.  Additionally,  controls  can  be  circumvented  by  the  individual  acts  of  some  persons,  by  collusion  of  two  or  more  people  or  by  an
unauthorized override of the controls. As a result, because of these inherent limitations in our control system, misstatements or omissions due to error or
fraud  may  occur  and  may  not  be  detected,  which  could  result  in  failures  to  file  required  reports  in  a  timely  manner  and  filing  reports  containing  incorrect
information. Any of these outcomes could result in SEC enforcement actions, monetary fines or other penalties, damage to our reputation, and harm to our
financial condition.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.

Market Information

Our common stock has been listed on The Nasdaq Global Market under the symbol “PSNL” since June 20, 2019. Prior to our initial public offering,

there was no public market for our common stock.

Holders

As of February 19, 2021, there were approximately 77 holders of record of our common stock. The actual number of stockholders is greater than
this  number  of  record  holders,  and  includes  stockholders  who  are  beneficial  owners,  but  whose  shares  are  held  in  street  name  by  brokers  and  other
nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

Dividend Policy

We have not declared or paid any cash dividend on our common stock. We intend to retain any future earnings and do not expect to pay cash
dividends in the foreseeable future. Payment of cash dividends, if any, in the future will be at the discretion of our board of directors and will depend on then-
existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our
board of directors may deem relevant.

58

Item 6. Selected Financial Data.

We are not providing selected financial data information as we are choosing to voluntarily comply with the revisions to Item 6 of Form 10-K, which

eliminated the disclosure requirements contained in Item 301 of Regulation S-K.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  should  be  read  in  conjunction  with  our  consolidated
financial statements and the related notes and other financial information included elsewhere in this Annual Report on Form 10-K. In addition to historical
consolidated  financial  information,  the  following  discussion  contains  forward-looking  statements  that  reflect  our  plans,  estimates,  and  beliefs.  Our  actual
results  could  differ  materially  from  those  discussed  in  the  forward-looking  statements.  You  should  review  the  sections  titled  “Special  Note  Regarding
Forward-Looking  Statements”  for  a  discussion  of  forward-looking  statements  and  in  Part  I,  Item  1A,  “Risk  Factors”  for  a  discussion  of  factors  that  could
cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and
analysis and elsewhere in this Annual Report on Form 10-K.

Overview

We  are  a  growing  cancer  genomics  company  transforming  the  development  of  next-generation  therapies  by  providing  more  comprehensive
molecular data about each patient’s cancer and immune response. We designed our NeXT Platform to adapt to the complex and evolving understanding of
cancer, providing our biopharmaceutical customers with information on all of the approximately 20,000 human genes, together with the immune system, in
contrast to many cancer panels that cover roughly only 50 to 500 genes. In parallel with the development of our platform technology, we have also pursued
business within the population sequencing market, and we have provided whole genome sequencing services under contract with the U.S. Department of
Veterans  Affairs  (the  “VA”)  Million  Veteran  Program  (the  “VA  MVP”),  which  has  enabled  us  to  innovate,  scale  our  operational  infrastructure,  and  achieve
greater  efficiencies  in  our  lab.  In  September  2020,  we  announced  receipt  of  a  new  task  order  from  the  VA  MVP  with  an  approximate  value  of  up  to  $31
million. The cumulative value of task orders received from the VA MVP since inception is approximately $175 million, approximately $132.5 million of which
we had recognized as revenue as of December 31, 2020.

In  August  2020,  we  launched  NeXT  Liquid  Biopsy,  which  is  a  liquid  biopsy  assay  that  analyzes  all  of  the  approximately  20,000  human  genes
versus the more narrowly focused liquid biopsy assays that are currently available. By combining technological innovation, operational scale, and regulatory
differentiation, our NeXT Platform is designed to help our customers obtain new insights into the mechanisms of response and resistance to therapy as well
as new potential therapeutic targets. Our platform enhances the ability of biopharmaceutical companies to unlock the potential of conducting translational
research in the clinic rather than with pre-clinical animal models or cancer cell lines. We also announced in January 2020 a diagnostic test, NeXT Dx Test,
which is based on our NeXT Platform, that we envision being used initially by both leading clinical cancer centers as well as biopharmaceutical companies.
Most  recently,  in  December  2020,  we  launched  two  new  capabilities  that  are  integrated  into  our  NeXT  Platform:  our  Systemic  HLA  Epitope  Ranking  Pan
Algorithm  (“SHERPA”)  machine  learning-based  tool  for  the  comprehensive  identification  and  characterization  of  cancer  neoantigens,  as  well  as  our
Neoantigen  Presentation  Score  (“NEOPS”)  for  predicting  cancer  immunotherapy  response.  SHERPA  enables  the  development  of  new  neoantigen-based
diagnostic biomarkers, such as our NEOPS, and novel personalized therapies.

We have the capacity to sequence and analyze approximately 200 trillion bases of DNA per week in our facility. We believe our capacity for this is
already larger than the sequencing capacities of most cancer genomics companies, and we continue to build automation and other infrastructure to scale
further as demand increases and in support of our NeXT Liquid Biopsy. To date, we have sequenced more than 150,000 human samples, of which more
than 100,000 were whole human genomes.

On August 14, 2020, we completed a follow-on equity offering in which we issued and sold 6,578,947 shares of common stock at a public offering
price of $19.00 per share. We received net proceeds of $117.5 million after deducting underwriting discounts and commissions. We also incurred $0.4 million
of offering expenses, including legal, accounting, printing and other offering-related costs.

Subsequent  to  the  fiscal  period  ended  December  31,  2020  covered  by  this  Annual  Report  on  Form  10-K,  on  January  29,  2021,  we  completed
another follow-on equity offering in which we issued and sold 3,950,000 shares of common stock at a public offering price of $38.00 per share. We received
net proceeds of $141.1 million after deducting underwriting discounts and commissions. The underwriters exercised their option to purchase an additional
592,500 shares shortly thereafter, resulting in additional net proceeds to us of $21.2 million after deducting underwriting discounts and commissions. In total,
we  raised  net  proceeds  of  $162.3  million  after  deducting  underwriting  discounts  and  commissions.  We  also  incurred  an  estimated  $0.4  million  of  offering
expenses, including legal, accounting, printing and other offering-related costs.

Our operations have been impacted by the ongoing COVID-19 pandemic. While the state and county reopening and health orders applicable to us
allow  for  continued  operation  of  so-called  Essential  Businesses,  which  includes  certain  critical  healthcare  operations  and  services,  we  have  substantially
closed  our  office  facilities  and  limited  access  to  our  laboratory  facilities  to  protect  our  employees  and  to  comply  with  the  provisions  described  within  the
orders.  We  provided  temporary  increased  pay  to  certain  laboratory  personnel  in  the  second  quarter  for  their  work  during  the  COVID-19  pandemic.  Such
increased pay was not provided in the third or fourth quarters, but we may decide to resume increased pay in the future. The previous shelter-in-place order
and current reopening and health orders have negatively impacted productivity, disrupted our business, and slowed research and development activities due
to us limiting access to our laboratory space that would otherwise be used by our research and development group, and, to the extent such orders remain in
place,  they  may  continue  to  cause  such  effects  on  our  operations.  The  reopening  and  health  orders  may  disrupt  the  ability  of  our  suppliers  to  fulfill  our
purchase orders in a timely manner or at all. Additionally, we are aware of increased demand in the market for certain consumables used in COVID-19 test
kits.  We  use  such  consumables  in  our  operations,  and  we  may  face  difficulties  in  acquiring  such  consumables  if  our  suppliers  prioritize  orders  related  to
COVID-19.  Several of our customers, including the  VA  MVP,  were  delayed  in  sending  us  samples  in  the  second  and  third  quarters  due  to  the  inability  to
collect or ship samples during the

60

COVID-19 pandemic, and these and additional customers may be disrupted from collecting samples or sending purchase orders and samples to us in the
future.  Many  of  our  customers,  potential  customers  and  potential  partners  have  also  put  in  place  policies  restricting  visitors  from  other  companies,  and
therefore our sales team and members of management have been unable to meet such parties in person, which may result in reduced acquisition of new
customers, fewer orders from existing customers, and fewer potential partnering opportunities. If our laboratory employees were to contract COVID-19, we
may significantly curtail our laboratory operations or pause operations altogether until the imminent health risk to our employees subsided. Such disruptions
in our operations, and our customers’ and suppliers’ operations, may continue to adversely affect revenues and operating results.

The  global  COVID-19  pandemic  continues  to  rapidly  evolve  and  to  present  serious  health  risks.  While  authorities  in  some  areas  have  lifted  or
relaxed certain of the restrictions described above, in some cases they have subsequently re-imposed various restrictions after observing an increased rate
of COVID-19 cases; for example, in December 2020, state and local authorities in California reinstated shelter-in-place orders in light of the increasing rate
of  COVID-19  cases  and  shortage  of  intensive  care  unit  beds  across  the  state.  Furthermore,  there  is  no  guarantee  when  or  if  all  such  restrictions  will  be
eliminated,  such  that  we  and  our  customers,  manufacturers  and  suppliers  will  be  able  to  safely  resume  operations  consistent  with  our  pre-COVID-19
operations. Vaccines against COVID-19 have been approved by the FDA and other regulatory authorities, but there is uncertainty as to when these vaccines
will be widely available to our employees and the population at large and how quickly and to what extent the vaccines will impact the COVID-19 pandemic.

While the extent of the impact of the current COVID-19 pandemic on our business and financial results is uncertain, a continued and prolonged

public health crisis such as the COVID-19 pandemic could have a material negative impact on our business, financial condition, and operating results.

Factors Affecting Our Performance

We  believe  there  are  several  important  factors  that  have  impacted,  and  that  we  expect  will  continue  to  impact,  our  operating  performance  and

results of operations, including:

•

•

•

•

•

The continued development of the market for genomic-based tests. Our performance depends on the willingness of biopharmaceutical
customers to continue to seek more comprehensive molecular information to develop more efficacious cancer therapies.

Increasing  adoption  of  our  products  and  solutions  by  existing  customers.  Our  performance  depends  on  our  ability  to  retain  and
broaden  adoption  with  existing  customers.  Because  our  technology  is  novel,  some  customers  begin  using  our  platform  by  initiating  pilot
studies involving a small number of samples to gain experience with our service. As a result, historically a significant portion of our revenues
has  come  from  existing  customers.  We  believe  that  our  ability  to  convert  initial  pilots  into  larger  orders  from  existing  customers  has  the
potential to drive substantial long-term revenue. We expect there may be some variation in the number of samples they choose to test each
quarter.

Adoption of our products and solutions by new customers. While new customers initially may not account for significant revenues, we
believe that they have the potential to grow substantially over the long term as they gain confidence in our service. Our ability to engage new
customers is critical to our long-term success. Our publications, posters and presentations at scientific conferences lead to engagement at
the  scientific level with potential customers who  often  make  the  initial  decision  to  gain  experience  with  our  platform.  Accessing  these  new
customers  through  scientific  engagement  and  marketing  to  gain  initial  buy-in  is  critical  to  our  success  and  gives  us  the  opportunity  to
demonstrate the utility of our platform.

Our revenues and costs are affected by the volume of samples we receive from customers from period to period. The timing and
size of sample shipments received after orders have been placed is variable. Since sample shipments can be large, and are often received
from a third party, the timing of arrival can be difficult to predict over the short term. Although our long-term performance is not affected, we
do see quarter-to-quarter volatility due to these factors. Samples arriving later than expected may not be processed in the quarter proposed
and result in revenue the following quarter. Since many of our customers request defined turnaround times, we employ project managers to
coordinate and manage the complex process from sample receipt to sequencing and delivery of results.

Investment in product innovation to support commercial growth. Investment in research and development, including the development of
new products and capabilities is critical to establish and maintain our leading position. We have invested significantly in our NeXT Platform,
introducing two new products and additional capabilities in 2020 alone: NeXT Liquid Biopsy (exome-wide liquid biopsy platform), NeXT Dx
Test  (comprehensive  genomic  cancer  profiling  test  enabling  advanced  composite  biomarkers  for  cancer  treatment),  NeXT  SHERPA  and
NeXT NEOPS (neoantigen prediction capabilities). We are currently investing in the development of future new product offerings, including
NeXT  Personal  (liquid  biopsy  offering  for  personalized  tumor  tracking  for  patients),  NeXT  CDx  (diagnostic  test),  and  NeXT  Database
(comprehensive tumor immune-genomics database). We are also collaborating with key opinion leaders from academic cancer centers, such
as Inova Health System and the Parker Institute for Cancer Immunotherapy, to support the clinical utility of our platform. We believe this work
is critical to gaining customer adoption and expect our investments in these efforts to increase.

61

 
 
 
 
 
•

Leverage our operational infrastructure. We have invested significantly, and will continue to invest, in our sample processing capabilities
and commercial infrastructure. With our current operating model and infrastructure, we can increase our production and commercialize new
generations of our platform, but as our volumes continue to increase we will ultimately need to invest in additional production capabilities. We
expect  to  grow  our  revenues  and  spread  our  costs  over  a  larger  volume  of  services.  In  addition,  we  may  invest  significant  amounts  in
infrastructure to support new products resulting from our research and development activities.

Components of Operating Results

Revenues

We derive our revenues primarily from sequencing and data analysis services to support the development of next-generation cancer therapies and
to  support  large-scale  genetic  research  programs.  We  support  our  customers  by  providing  high-accuracy,  validated  genomic  sequencing  and  advanced
analytics. Many of these analytics are related to state-of-the-art biomarkers, including those relevant to immuno-oncology therapeutics such as checkpoint
inhibitors.

Our revenues are primarily generated through contracts with companies in the pharmaceutical industry, healthcare organizations, and government
entities. Our ability to increase our revenues will depend on our ability to further penetrate this market. To do this, we are developing a growing set of state-
of-the-art products, advancing our operational infrastructure, expanding our international presence, building our regulatory credentials, and expanding our
targeted marketing efforts. Unlike diagnostic or therapeutic companies, we have not to date sought reimbursement through traditional healthcare payors. We
sell through a small direct sales force.

We derive a substantial portion of our current and expected future revenues from sales of our DNA sequencing and data analysis services to the
VA MVP. Our contract with the VA MVP does not include specific testing turnaround times. Therefore, we have the ability to modulate the volume of samples
processed for the VA MVP up or down to complement sample volumes from all other customers, which can vary from period to period.

We  have  one  reportable  segment  from  the  sale  of  sequencing  and  data  analysis  services.  Substantially  all  of  our  revenues  to  date  have  been

derived from sales in the United States.

Costs and Expenses

Costs of revenues

Costs  of  revenues  consist  of  raw  materials  costs,  personnel  costs  (salaries,  bonuses,  stock-based  compensation,  payroll  taxes,  and  benefits),
laboratory  supplies  and  consumables,  depreciation  and  maintenance  on  equipment,  and  allocated  facilities  and  information  technology  (“IT”)  costs.  We
expect costs of revenues to increase as our revenues grow, and in the short term costs of revenues may outpace revenue growth as we invest in expanding
our laboratory capacity, but over time the cost per sample processed is expected to decrease due to economies of scale we may gain as volume increases,
automation initiatives, and other cost reductions.

Research and development expenses

Research  and  development  expenses  consist  of  costs  incurred  for  the  research  and  development  of  our  products.  These  expenses  consist
primarily  of  personnel  costs  (salaries,  bonuses,  stock-based  compensation,  payroll  taxes,  and  benefits),  laboratory  supplies  and  consumables,  costs  of
purchasing samples for research purposes, depreciation and maintenance on equipment, and allocated facilities and IT costs. We include in research and
development expenses the costs to further develop software we use to operate our laboratory, analyze the data it generates, and automate our operations.
These expenses also include costs associated with our collaborations, which we expect to increase over time.

We  expense  our  research  and  development  expenses  in  the  period  in  which  they  are  incurred.  We  expect  to  increase  our  research  and

development expenses as we continue to develop new products.

Selling, general, and administrative expenses

Selling expenses consist of personnel costs (salaries, commissions, bonuses, stock-based compensation, payroll taxes, and benefits), customer
support expenses, direct marketing expenses, and market research. Our general and administrative expenses include costs for our executive, accounting,
finance, legal, and human resources functions. These expenses consist of personnel costs (salaries, bonuses, stock-based compensation, payroll taxes, and
benefits),  corporate  insurance,  audit  and  legal  expenses,  consulting  costs,  and  allocated  facilities  and  IT  costs.  We  expense  all  selling,  general  and
administrative expenses as incurred.

We expect our selling expenses will continue to increase in absolute dollars, primarily driven by our efforts to expand our commercial capability
and to expand our brand awareness and customer base through targeted marketing initiatives with an increased presence both within and outside the United
States. We also expect general and administrative expenses to increase as we scale our operations.

62

 
Interest Income

Interest  income  consists  primarily  of  interest  earned  on  our  cash  and  cash  equivalents  and  short-term  investments.  Interest  income  increased
significantly beginning in the second half of 2019 as a result of us investing proceeds from the initial public offering of our common stock in June 2019 (our
“IPO”). More recently, interest income has been adversely impacted by recent declines in yields on debt securities. We expect that our interest income will
continue to decline in the near future as the decline in yields is expected to more than offset the increased investments balances after our August 2020 and
January 2021 follow-on offerings.

Interest Expense

Previously,  interest  expense  primarily  consisted  of  cash  and  non-cash  interest  costs  related  to  our  term  loan,  convertible  promissory  notes,
revolving loan and security agreement (the “Revolving Loan”) with TriplePoint Capital LLC (“TriplePoint”), and growth capital loan (the “Growth Capital Loan”)
with TriplePoint. After the payoff of our Growth Capital Loan in August 2019, we no longer have any outstanding debt and have not incurred material interest
expense from that point forward.

Loss on Debt Extinguishment

We incurred a loss on debt extinguishment in 2018 resulting from changes in the maturity dates of the convertible notes issued in 2017. We also
incurred a loss on debt extinguishment in 2019 upon the payoff of the Growth Capital Loan. See Note 6 to our consolidated financial statements included
elsewhere in this annual report.

Other Income (Expense), Net

Other  income  (expense),  net  consists  primarily  of  foreign  currency  exchange  gains  and  losses.  In  2019,  other  income  (expense),  net  also
consisted of changes in fair value of convertible preferred stock warrant liability. Due to the conversion of convertible preferred stock warrants to common
stock warrants upon our IPO, changes in fair value of such warrants are no longer recorded through income since our IPO. See Note 10 to our consolidated
financial statements included elsewhere in this annual report for further discussion of this item. We expect our foreign currency gains and losses to continue
to fluctuate in the future due to changes in foreign currency exchange rates.

The increase in revenues from the VA MVP in 2020 was driven by an increase in the volume of samples we tested in the period. This increase
was driven by a significant rise in the number of samples we received from the VA MVP for testing during 2020 compared to those received for testing during
2019. Our increasingly automated laboratory has supported this higher level of sample volumes.

All Other Customers

The increase in revenues from all other customers in 2020 was driven primarily by an increase in the volume of samples we tested in the period.
Approximately  $1.0  million  of  the  increase  was  attributed  to  a  new  biobank  customer  and  $0.65  million  of  the  increase  in  revenues  was  related  to  the
completion of a research collaboration with a biopharmaceutical customer in the gene therapy space. Approximately one-third of total revenues from all other
customers were derived from our NeXT Platform products, whereas revenues from NeXT products in 2019 were insignificant.

The increase in costs of revenues in 2020 was primarily due to the increase in revenue volume, including from the VA MVP, discussed above. The
cost  components  related  to  the  increase  in  costs  of  revenues  were  a  $10.3  million  increase  in  raw  materials  due  primarily  to  higher  VA  MVP  sample
volumes; a $2.3 million increase related to personnel-related costs; a $0.9 million increase in depreciation and maintenance costs due to our additions of
laboratory equipment; a $0.8 million increase in the cost of laboratory supplies and consumables; a $0.6 million increase in IT and facility costs; and a $0.5
million increase in other costs. Costs of revenues increased more than revenues primarily due to increased raw materials costs and the addition of laboratory
personnel in anticipation of higher future laboratory throughput.

Research and development

The increase in research and development in 2020 was primarily due to development of new products and capabilities (such as those noted in the
Factors Affecting Our Performance section above) and lab automation efforts, and consisted of an increase of $6.1 million in personnel-related costs; a $0.9
million  increase  in  IT  and  facilities  costs;  and  a  $0.7  million  increase  in  other  costs,  partially  offset  by  a  $1.5  million  decrease  in  laboratory  supplies  and
consumables for research and development projects.

Selling, general and administrative

The  increase  in  selling,  general  and  administrative  in  2020  was  due  to  a  $8.8  million  increase  in  personnel-related  costs  primarily  related  to
increased  headcount  to  support  expansion  of  our  commercial  team;  a  $3.0  million  increase  in  professional  services  primarily  related  to  public  company-
related costs (including corporate insurance, audit fees, and legal expenses), partially offset by a $0.2 million decrease in other costs.

The decrease in interest income in 2020 was driven by declines in yields on debt securities, partially offset by higher average cash and investment

balances subsequent to our follow-on offering in August 2020.

Interest expense

Interest expense in 2019 included cash and non-cash interest expense related to the Revolving Loan and Growth Capital Loan. The Revolving
Loan  was  paid  off  in  late  March  2019  with  proceeds  from  the  Growth  Capital  Loan.  The  Growth  Capital  Loan  was  fully  repaid  in  August  2019.  Since  we
repaid the Growth Capital Loan, we have had no outstanding debt and therefore did not incur significant interest expense in 2020.

Loss on debt extinguishment

The $1.7 million loss on debt extinguishment in 2019 resulted from the extinguishment of our $20 million Growth Capital Loan facility.

Other Income (Expense), Net

Other  expense  in  2020  was  primarily  comprised  of  foreign  currency  remeasurements.  Other  expense  in  2019  was  primarily  comprised  of
increases in the fair values of warrants for Series B and Series C redeemable convertible preferred stock as a result of increases to the estimated fair value
of our equity during the period.

From our inception through December 31, 2020, we have funded our operations primarily from $117.5 million in net proceeds from our follow-on
offering  in  August  2020,  $144.0  million  in  net  proceeds  from  our  IPO  in  June  2019,  and  $89.6  million  from  issuance  of  redeemable  convertible  preferred
stock, as well as cash from operations and debt financing. As of December 31, 2020, we had cash and cash equivalents in the amount of $68.5 million and
short-term investments in the amount of $134.8 million.

We have incurred net losses since our inception. We anticipate that our current cash and cash equivalents and short-term investments, together

with cash provided by operating activities, are sufficient to fund our near-term capital and operating needs for at least the next 12 months.

We  have  based  these  future  funding  requirements  on  assumptions  that  may  prove  to  be  wrong,  and  we  could  utilize  our  available  capital
resources sooner than we expect. If our available cash balances, net proceeds from the offerings and anticipated cash flow from operations are insufficient
to satisfy our liquidity requirements, including because of lower demand for our services or other risks described in this Annual Report on Form 10-K, such
as the COVID-19 pandemic, we may seek to sell additional common or preferred equity or convertible debt securities, enter into an additional credit facility or
another form of third-party funding or seek other debt financing. The sale of equity and convertible debt securities may result in dilution to our stockholders
and, in the case of preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our
common  stock.  The  terms  of  debt  securities  issued  or  borrowings  pursuant  to  a  credit  agreement  could  impose  significant  restrictions  on  our  operations.
Additional capital may not be available on reasonable terms, or at all.

Our  short-term investments portfolio is primarily  invested  in  highly  rated  securities,  with  the  primary  objective  of  minimizing  the  potential  risk  of

principal loss. Our investment policy generally requires securities to be investment grade and limits the amount of credit exposure to any one issuer.

During 2020, cash used in operating activities of $42.7 million was a result of $41.3 million of net loss and the net negative change in operating
assets  and  liabilities  of  $17.2  million  ($14.9  million  of  which  was  related  to  reductions  in  outstanding  customer  prepayments  as  we  fulfilled  the  related
revenue contracts), partially offset by non-cash adjustments to net income of $15.8 million (the most significant non-cash expenses for us in 2020 were $8.2
million of stock-based compensation and $5.8 million of depreciation and amortization).

During 2019, cash used by operating activities of $18.1 million was a result of $25.1 million of net loss and the net negative change in operating

assets and liabilities of $7.3 million, partially offset by non-cash negative adjustments to net income of $14.3 million.

During 2020, cash used in investing activities was $65.1 million due to net purchases of short-term investments of $61.9 million and $3.2 million
acquisitions of property and equipment used for our sequencing and data analysis services. Cash provided by financing activities of $121.3 million during the
same period consisted of $117.5 million net proceeds from our August 2020 follow-on offering, $2.8 million proceeds from stock option exercises, and $1.4
million proceeds from ESPP purchases, partially offset by $0.4 million payments in offering costs.

During  2019,  cash  used  by  investing  activities  of  $81.6  million  consisted  of  net  purchases  of  short-term  investments  of  $73.2  million  and  cash
used  to  acquire  property  and  equipment  of  $8.4  million.  Cash  provided  by  financing  activities  of  $134.9  million  during  2019  consisted  primarily  of  $139.8
million of proceeds from our IPO, net of underwriting discounts and commissions, $1.4 million of proceeds from issuance of common stock under employee
stock plans, and net proceeds from the issuance of a Growth Capital Loan of $20.0 million, partially offset by cash used to repay a revolving loan and issue
and repay the Growth Capital Loan of $26.3 million.

Material Cash Requirements for Known Contractual and Other Obligations

The following is a description of commitments for capital expenditures and other known and reasonably likely cash requirements as of December
31,  2020.  We  anticipate  fulfilling  such  commitments  with  our  existing  cash  and  cash  equivalents  and  short-term  investments,  which  amounted  to  $203.3
million as of December 31, 2020.

Our non-cancellable operating lease payments were $15.5 million as of December 31, 2020. The timing of these future payments, by year, can be

found in Part II, Item 8 of this Form 10-K in the Notes to Consolidated Financial Statements in Note 7, “Leases.”

We had capital expenditures commitments in the amount of approximately $1.7 million as of December 31, 2020, which was comprised primarily
of laboratory equipment and computer equipment. Such purchases will likely occur within the first half of 2021. Furthermore, overall capital expenditures in
2021 will likely exceed total capital expenditures in 2020.

We  previously  entered  into  various  forms  of  convertible  debt  and  revolving  loans  to  finance  our  operations  prior  to  our  IPO.    We  paid  off  all
remaining  debt  in  August  2019  and  have  incurred  no  additional  debt  since.  Further  information  regarding  the  Company’s  debt  issuances  and  payment
commitments can be found in Part II, Item 8 of this Form 10-K in the Notes to Consolidated Financial Statements in Note 6, “Borrowings.”

Certain  of  our  customers  prepay  us  for  a  portion  of  the  services  that  they  expect  to  order  from  us  before  they  place  purchase  orders  and  we
deliver  those  services.  In  some  cases,  this  prepayment  can  be  substantial  and  may  be  paid  months  or  a  year  or  more  in  advance  of  these  customers
providing samples to us and before our delivery of the services to which some or all of the deposit relates.

67

 
As  of  December  31,  2020,  we  had  approximately  $21.0  million  in  customer  deposits,  including  $18.4  million  from  one  customer.  We  are  generally  not
required by our contracts to retain these deposits in cash or otherwise and we have generally used these deposits to make capital expenditures and fund our
operations. When a customer that has prepaid us for future services cancels its contract with us or reduces the level of services that it expects to receive, we
are required to repay that customer’s deposit with little or no notice. We do not expect to refund material amounts of cash under such circumstances.

Critical Accounting Policies and Estimates

Our  consolidated  financial  statements  are  prepared  in  accordance  with  U.S.  GAAP.  The  preparation  of  these  consolidated  financial  statements
requires  us  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets,  liabilities,  revenues,  costs  and  expenses,  and  related
disclosures. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the
results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual
results may differ 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 possible
could materially impact the financial statements. We believe that the assumptions and estimates associated with the accounting policies discussed below
have  the  greatest  potential  impact  on  our  consolidated  financial  statements.  Therefore,  we  consider  these  to  be  our  critical  accounting  policies  and
estimates.

Revenue Recognition

Revenue Recognition

We generate our revenues from selling sequencing and data analysis services. We agree to provide services to our customers through a contract,

which may be in the form of a combination of a signed agreement, statement of work and/or a purchase order.

We have evaluated the performance obligations contained in contracts with customers to determine whether any of the performance obligations
are  distinct,  such  that  the  customers  can  benefit  from  the  obligations  on  their  own,  and  whether  the  obligations  can  be  separately  identifiable  from  other
obligations  in  the  contract.  For  the  significant  majority  of  our  contracts  to  date,  the  customer  orders  a  specified  quantity  of  a  sequencing;  therefore,  the
delivery  of  the  ordered  quantity  per  the  purchase  order  is  accounted  for  as  one  performance  obligation.  Our  contracts  include  only  one  performance
obligation—the delivery of the sequencing and data analysis services to the customer.

Fees  for  our  sequencing  and  data  analysis  services  are  predominantly  based  on  a  fixed  price  per  sample.  The  fixed  prices  identified  in  the
arrangements  only  change  if  a  pricing  amendment  is  agreed  with  a  customer.  In  limited  cases  we  provide  our  customers  a  discount  if  samples  received
above a certain volume are purchased. In such cases, the discount applies prospectively. We have analyzed such discounts if they represent a material right
provided to a customer. We have concluded that such discounts do not represent a material right provided to a customer since they are not deemed to be
incremental to the pricing offered to the customer or are not enforceable options to acquire additional goods. As a result, these discounts do not constitute a
material right and do not meet the definition of a separate performance obligation. We do not offer retrospective discounts or rebates. Accordingly, all of the
transaction  price,  net  of  any  discounts,  is  allocated  to  one  performance  obligation.  Therefore,  upon  delivery  of  the  services,  there  are  no  remaining
performance obligations.

Contracts that contain multiple distinct performance obligations would require an allocation of the transaction price to each performance obligation
based on a relative stand-alone selling price basis. Sometimes we deliver sequencing results in two or more batches; however, since the quantity delivered
per batch of each individual test per sales order in these instances is in the same ratio as in the original sales order, allocating the transaction price on a
relative stand-alone selling price basis would have no impact on the revenue recognized in any period presented.

We recognize revenue when control of the promised services is transferred to our customers. Management applies judgment in evaluating when a
customer obtains control of the promised service, which is when the sequencing and data analysis service results are delivered to customers, at an amount
that  reflects  the consideration to which we expect  to  be  entitled  to  in  exchange  for  those  services.  Revenue  is  recorded  net  of  sales  or  other  transaction
taxes collected from clients and remitted to taxing authorities.

A  customer  contract  liability  will  arise  when  we  have  received  payments  from  its  customers  in  advance,  but  has  not  yet  provided  genome  and
exome  sequencing  and  data  analysis  services  to  a  customer  and  satisfied  its  performance  obligations.  We  record  a  customer  contract  liability  for
performance  obligations  outstanding  related  to  payments  received  in  advance  for  customer  deposits.  We  expect  to  satisfy  these  remaining  performance
obligations and recognize the related revenues upon providing sequencing and data analysis services.

All of our revenues and trade receivables are generated from contracts with customers and substantially all of our revenues are derived from U.S.
domestic operations. The following section describes the accounting policies that we believe have significant judgment, or changes in judgment, as a result
of adopting ASC Topic 606.

68

Payment Terms

Payment  terms  and  conditions  vary  by  contract  and  customer.  Our  standard  payment  terms  are  typically  less  than  90  days  from  the  date  of
invoice. In instances where the timing of our revenue recognition differs from the timing of its invoicing, we have determined that our contracts do not include
a significant financing component. The primary purposes of our invoicing terms are to provide customers with simplified and predictable ways of purchasing
our services and provide payment protection for us.

Stock-Based Compensation

We account for stock-based compensation arrangements with employees, using a fair value-based method, for costs related to all stock-based
payments  including  stock  options  and  stock  awards.  Our  determination  of  the  fair  value  of  stock  options  on  the  date  of  grant  utilizes  the  Black-Scholes
option-pricing model.

The fair value of the option granted is recognized over the period during which an optionee is required to provide services in exchange for the

option award, known as the requisite service period which usually is the vesting period, on a straight-line basis.

Estimating the fair value of equity-settled awards as of the grant date using valuation models, such as the Black-Scholes option-pricing model, is
affected by assumptions regarding a number of complex variables. Changes in the assumptions can materially affect the fair value and ultimately how much
stock-based compensation expense is recognized. These inputs are subjective and generally require significant analysis and judgment to develop.

•

•

•

•

Expected Term—The  expected  term  assumption  represents  the  weighted-average  period  that  the  stock-based  awards  are  expected  to  be
outstanding.  We  have  elected  to  use  the  “simplified  method”  for  estimating  the  expected  term  of  the  options,  whereby  the  expected  term
equals the arithmetic average of the vesting term and the original contractual term of the option.

Expected Volatility—For all stock options granted to date, the volatility data was estimated based on a study of publicly traded industry peer
companies. For purposes of identifying these peer companies, we considered the industry, stage of development, size, and financial leverage
of potential comparable companies.

Expected  Dividend  Yield—The  Black-Scholes  option-pricing  valuation  model  calls  for  a  single  expected  dividend  yield  as  an  input.  We
currently have no history or expectation of paying cash dividends on our common stock.

Risk-Free Interest Rate—The risk-free interest rate is based on the yield available on U.S. Treasury zero-coupon issues similar in duration to
the expected term of the equity-settled award.

We estimated the fair value of the time-based employee stock options using the Black-Scholes option-pricing model based on the date of grant

with the following assumptions:

Common Stock Valuations

The estimated fair value of the common stock underlying our stock options was determined at each grant date by our board of directors, with input
from management. All options to purchase shares of our common stock are intended to be exercisable at a price per share not less than the per-share fair
value of our common stock underlying those options on the date of grant.

In the absence of a public trading market for our common stock prior to our IPO, on each grant date, we developed an estimate of the fair value of
our common stock based on the information known to us on the date of grant, upon a review of any recent events and their potential impact on the estimated
fair  value  per  share  of  the  common  stock,  and  in  part  on  input  from  an  independent  third-party  valuation  firm.  As  provided  in  Section  409A  of  the  U.S.
Internal Revenue Code of 1986, as amended (the “Code”), we generally relied on our valuations for up to 12 months unless we experienced a material event
that would have affected the estimated fair value per common share.

Our  valuations  of  our  common  stock  were  determined  in  accordance  with  the  guidelines  outlined  in  the  American  Institute  of  Certified  Public
Accountants  Practice  Aid,  Valuation  of  Privately-Held-Company  Equity  Securities  Issued  as  Compensation  (the  “Practice  Aid”).  The  methodology  to
determine  the  fair  value  of  our  common  stock  included  estimating  the  fair  value  of  the  enterprise  using  the  “backsolve”  method,  which  estimates  the  fair
value of our company by reference to the value and preferences of our last round of financing, as well as our capitalization.

The  assumptions  used  to  determine  the  estimated  fair  value  of  our  common  stock  were  based  on  numerous  objective  and  subjective  factors,
combined with management’s judgment, including external market conditions affecting the pharmaceutical and biotechnology industry and trends within the
industry:

•

•

our stage of development;

the rights, preferences, and privileges of our redeemable convertible preferred stock relative to those of our common stock;

69

 
 
 
 
 
 
•

•

•

•

•

the prices at which we sold shares of our redeemable convertible preferred stock;

our financial condition and operating results, including our levels of available capital resources;

the progress of our research and development efforts, our stage of development, and business strategy;

equity market conditions affecting comparable public companies; and

general U.S. market conditions and the lack of marketability of our common stock.

The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the

estimated fair value of common stock at each valuation date. In accordance with the Practice Aid, we considered the following methods:

•

•

•

Income  approach.  The  income  approach  attempts  to  value  an  asset  or  security  by  estimating  the  present  value  of  the  future  economic
benefits  it  is  expected  to  produce.  These  benefits  can  include  earnings,  cost  savings,  tax  deductions,  and  disposition  proceeds  from  the
asset. An indication of value may be developed in this approach by discounting expected cash flows to their present value at a rate of return
that incorporates the risk-free rate for the use of funds, the expected rate of inflation over the asset’s holding period, and the risks associated
with  realizing  the  cash  flows  in  the  amounts  and  at  the  times  projected.  The  discount  rate  selected  is  typically  based  on  rates  of  return
available from alternative investments of similar type and quality as of the valuation date. The most commonly employed income approach to
valuation is the discounted cash flow analysis.

Market Approach. The market approach attempts to value an asset or security by examining observable market values for similar assets or
securities.  Sales  and  offering  prices  for  comparable  assets  are  adjusted  to  reflect  differences  between  the  asset  being  valued  and  the
comparable assets, such as, location, time and terms of sale, utility, and physical characteristics. When applied to the valuation of equity, the
analysis  may  include  consideration  of  the  financial  condition  and  operating  performance  of  the  company  being  valued  relative  to  those  of
publicly traded companies or to those of companies acquired in a single transaction, which operate in the same or similar lines of business.

Cost Approach. The cost approach to valuation is based upon the concept of replacement cost as an indicator of value and the notion that an
investor would pay no more for an asset than what it would cost to replace the asset with one of equal utility. The cost approach estimates
value  based  upon  the  estimated  cost  of  replacing  or  reproducing  the  asset,  less  adjustments  for  physical  deterioration  and  functional
obsolescence,  if  relevant.  When  applied  to  an  enterprise,  a  type  of  cost  approach  referred  to  as  the  Net  Asset  Method  is  sometimes
employed. This method measures the value of equity as the sum of the values of its assets reduced by the sum of the values of its liabilities.
The  resulting  equity  is  reflective  of  a  100%  ownership  interest  in  the  business.  This  approach  is  frequently  used  in  valuing  holding
companies.

Based on our early stage of development and other relevant factors, we considered all three approaches and chose to apply both income and
market approaches in our analyses. We determined these approaches were the most appropriate methods for allocating our enterprise value to determine
the  estimated  fair  value  of  our  common  stock  for  valuations  performed  for  periods  up  to  our  IPO.  In  determining  the  estimated  fair  value  of  our  common
stock, our board of directors also considered the fact that our stockholders could not freely trade our common stock in the public markets. Accordingly, we
applied discounts to reflect the lack of marketability of our common stock based on the weighted-average expected time to liquidity. The estimated fair value
of our common stock at each grant date reflected a non-marketability discount partially based on the anticipated likelihood and timing of a future liquidity
event.

Following our IPO, our board of directors determines the fair value of our common stock based on the closing quoted market price of our common

stock on the date of grant.

JOBS Act Accounting Election

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). Under the JOBS Act, emerging
growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those
standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and
therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

PERSONALIS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Company and Nature of Business

Personalis, Inc. (the “Company”) was incorporated in Delaware on February 21, 2011 and began operations in September 2011. The Company
formed a wholly owned subsidiary, Personalis (UK) Ltd., in August 2013 and a wholly owned subsidiary, Shanghai Personalis Biotechnology Co., Ltd. (which
is referred to as “Personalis (Shanghai) Ltd” herein), in October 2020. The Company is a growing cancer genomics company transforming the development
of next-generation therapies by providing more comprehensive molecular data about each patient’s cancer and immune response. The Company provides
sequencing and data analysis services to support the development of cancer therapies. The Company also provides sequencing and data analysis services
to  support  population  sequencing  initiatives,  which  accounts  for  the  majority  of  revenues.  Cancer  genomic  services  are  sold  primarily  to  pharmaceutical
companies,  biopharmaceutical  companies,  universities,  non-profits,  and  government  entities,  while  services  for  population  sequencing  initiatives  are  sold
primarily to government entities. The principal markets for the Company’s services are the United States and Europe. In June 2020, the Company began
partnering with a clinical genomics and life sciences company headquartered in China as a means to expand business operations into China. The Company
operates and manages its business as one reportable operating segment, which is the sale of sequencing and data analysis services.

The Company has incurred losses to date and expects to incur additional losses for the foreseeable future. The Company continues to invest the
majority of its resources in the development and growth of its business, including investments in product development and sales and marketing efforts. The
Company’s activities have been financed to date primarily through the sale of equity securities and cash from operations.

Note 2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of
America  (“U.S.  GAAP”)  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange  Commission  (“SEC”)  regarding  annual  reporting.  The
consolidated financial statements include the accounts of Personalis, Inc. and its wholly owned subsidiaries, Personalis (UK) Ltd. and Personalis (Shanghai)
Ltd. All intercompany balances and transactions have been eliminated in consolidation.

The  Company  began  presenting  “Long-term  operating  lease  liabilities”  and  “Operating  lease  liabilities”  separately  in  the  consolidated  balance
sheets and consolidated statements of cash flows, respectively, in 2020. Amounts reported in previous periods were reclassified to conform to the current
presentation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements
and the reported amounts of revenues and expenses during the reporting period. The estimates include, but are not limited to, useful lives assigned to long-
lived  assets,  the  valuation  of  common  and  convertible  redeemable  preferred  stock  and  related  warrants  and  options,  the  valuation  of  the  compound
derivative  instrument,  the  valuation  of  stock-based  awards,  and  provisions  for  income  taxes  and  contingencies.  Actual  results  could  differ  from  these
estimates, and such differences could be material to the Company’s consolidated financial position and results of operations.

Reverse Stock Split

On June 4, 2019, the Company filed an amendment to the Company’s amended and restated certificate of incorporation to effect a reverse split of
shares of the Company’s common stock and redeemable convertible preferred stock on a four-for-one basis (the “Reverse Stock Split”). The par value of the
common stock and redeemable convertible preferred stock was not adjusted as a result of the Reverse Stock Split. All references to common stock, options
to  purchase  common  stock,  share  data,  per  share  data,  redeemable  convertible  preferred  stock  and  related  information  contained  in  these  consolidated
financial statements have been retrospectively adjusted to reflect the effect of the Reverse Stock Split for all periods presented.

Initial Public Offering

On June 24, 2019, the Company completed an initial public offering (“IPO”) in which it issued and sold 9,109,725 shares of its common stock at a
public offering price of $17.00 per share. The Company received net proceeds of $139.8 million after deducting underwriting discounts, commissions and
offering expenses. Offering expenses were $4.2 million and consisted of fees and expenses incurred in connection with the sale of the Company’s common
stock in the IPO, including legal, accounting, printing, and other IPO-related costs.

A warrant to purchase 188,643 shares of our common stock was exercised prior to completion of the IPO. In addition, in connection with the IPO,

all shares of the Company’s then-outstanding redeemable convertible preferred stock were automatically

77

 
converted into 18,474,703  shares  of  the  Company’s  common  stock,  and  all  then-outstanding  warrants  to  purchase  the  Company’s  convertible  preferred
stock were automatically converted into warrants to purchase 84,585 shares of the Company’s common stock, all of which were exercised as of December
31, 2020 (see Note 10).

Follow-On Offering

On August 14, 2020, the Company completed a follow-on offering in which it issued and sold 6,578,947 shares of its common stock at a public
offering price of $19.00 per share. The Company received net proceeds of $117.1 million after deducting underwriting discounts, commissions, and offering
expenses. Offering expenses were $0.4 million consisting of legal, accounting, printing and other offering-related costs.

Concentration of Credit Risk and Other Risks and Uncertainties

The Company is subject to credit risk from its portfolio of cash and cash equivalents. The Company’s cash and cash equivalents are deposited
with  high-quality  financial  institutions.  Deposits  at  these  institutions  may,  at  times,  exceed  federally  insured  limits.  Management  believes  these  financial
institutions are financially sound and, accordingly, that minimal credit risk exists. The Company has not experienced any losses on its deposits of cash and
cash equivalents.

The  Company also invests in investment‑grade  debt  instruments  and  has  policy  limits  for  the  amount  it  can  invest  in  any  one  type  of  security,
except for securities issued or guaranteed by the U.S. government. The goals of the Company’s investment policy are as follows: preservation of principal;
liquidity  of  investments  sufficient  to  meet  cash  flow  requirements;  avoidance  of  inappropriate  concentration  and  credit  risk;  competitive  after‑tax  rate  of
returns;  and  fiduciary  control  of  cash  and  investments.  Under  its  investment  policy,  the  Company  limits  the  amounts  invested  in  such  securities  by  credit
rating,  maturity,  investment  type,  and  issuer.  As  a  result,  management  believes  that  these  financial  instruments  do  not  expose  the  Company  to  any
significant concentrations of credit risk.

The Company purchases various reagents and sequencing materials from sole source suppliers. Any extended interruption in the supply of these

materials could result in the Company’s inability to secure sufficient materials to conduct business and meet customer demand.

The Company routinely assesses the creditworthiness of its customers and does not require collateral. The Company has not experienced any
material losses related to receivables from individual customers, or groups of customers. The Company maintains an allowance for doubtful accounts, which
was $0.1 million as of December 31, 2020 and 2019. During the year ended December 31, 2019, bad debt expense was $0.1 million and included in selling,
general and administrative expenses. The Company had no bad debt expense in 2020 and 2018.

Significant customers are those that represent more than 10% of the Company’s total revenues or accounts receivable balance at each respective
balance sheet date. For each significant customer, revenue as a percentage of total revenues and accounts receivable as a percentage of total accounts
receivable are as follows:

VA MVP
Pfizer Inc.
Merck & Co., Inc.
Indivumed GmbH

The  Company  applies  the  revenue  recognition  guidance  in  accordance  with  Financial  Accounting  Standards  Board  (“FASB”)  Accounting

Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”).

Revenue Recognition

The  revenue  guidance  provides  a  five-step  framework  through  which  revenue  is  recognized  when  control  of  promised  goods  or  services  is
transferred to a customer at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To
determine revenue recognition for arrangements that the Company concludes are within the scope of Topic 606, management performs the following five
steps: (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract(s); (iii) determines the transaction price, including
whether there are any constraints on variable consideration; (iv) allocates the transaction price to the performance obligations; and (v) recognizes revenue
when (or as) the Company satisfies a performance obligation. At contract inception, once a contract is determined to be within the scope of the new revenue
standard,  the  Company  assesses  whether  individual  goods  or  services  promised  within  each  contract  are  distinct  and,  therefore,  represent  separate
performance obligations.

The  Company  derives  revenues  from  sequencing  and  data  analysis  services  to  support  the  development  of  personalized  cancer  vaccines  and
other  next-generation  cancer  immunotherapies,  as  well  as  to  support  population  sequencing  initiatives.  The  Company’s  contracts  are  in  the  form  of  a
combination  of  signed  agreements,  statements  of  work,  and/or  purchase  orders.  Under  Topic  606,  the  Company  accounts  for  a  contract  with  a  customer
when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial
substance, and it is probable that the Company will collect substantially all of the consideration to which it will be entitled.

The sequencing and data analysis services are the only distinct services that meet the definition of a performance obligation and are accounted
for as one performance obligation under Topic 606. The Company recognizes revenue from such services at the point in time when control of the test results
is  transferred  to  the  customer.  The  Company  has  elected  to  exclude  all  sales  and  value  added  taxes  from  the  measurement  of  the  transaction  price.
Sequencing and data analysis services are based on a fixed price per test.

Payment terms and conditions vary by contract and customer. The Company’s standard payment terms are less than 90 days from the invoice
date. In instances where the timing of the Company’s revenue recognition differs from the timing of its invoicing, the Company does not assess whether a
contract  has  a  significant  financing  component  if  the  expectation  at  contract  inception  is  such  that  the  period  between  payment  by  the  customer  and  the
transfer  of  the  promised  services  to  the  customer  will  be  one  year  or  less.  After  assessing  each  of  its  revenue-generating  arrangements  to  determine
whether a significant financing component exists, the Company concluded that a significant financing component does not exist in any of its arrangements.
The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s services
and to provide payment protection for the Company.

Practical Expedients and Exemptions

As a practical expedient, the Company recognizes the incremental costs of obtaining contracts, such as sales commissions, as an expense when
incurred  since  the  amortization  period  of  the  asset  the  Company  otherwise  would  have  recognized  is  one  year  or  less.  Sales  commissions  are  recorded
within selling, general, and administrative expenses in the consolidated statements of operations.

Costs of Revenues

Costs  of  revenues  consist  of  raw  materials  costs,  personnel  costs  (salaries,  bonuses,  benefits,  payroll  taxes,  and  stock-based  compensation),

laboratory supplies and consumables, depreciation and maintenance on equipment, and allocated facilities and information technology costs.

Research and Development Expenses

The Company charges research and development costs to expenses as incurred, including lab and automation development costs. The expenses
primarily consist of personnel costs (salaries, bonuses, stock-based compensation, payroll taxes, and benefits), laboratory supplies and consumables, costs
of purchasing samples for research purposes, depreciation and maintenance on equipment, and allocated facilities and information technology costs.

Stock-Based Compensation

For options granted to employees, non-employees, and directors, stock-based compensation is measured at grant date based on the fair value of
the award. The Company determines the grant-date fair value of the options using the Black-Scholes option-pricing model, except for certain performance-
based  awards  for  which  an  alternative  valuation  method  may  be  used.  The  Company  determines  the  fair  value  of  restricted  stock  unit  awards  using  the
closing market price of the Company’s common stock on the date of grant. The grant-date fair value of awards is amortized over the employees’ requisite
service period on a straight-line basis, or the non-employees’ vesting period as the goods are received or services rendered. Forfeitures are accounted for
as they occur. Additionally, the Company’s 2019 Employee Stock Purchase Plan is deemed to be a compensatory plan and therefore is included in stock-
based compensation expense.

Inputs used in Black-Scholes option-pricing models to measure fair value of options are summarized as follows:

Expected Term. The expected term is calculated using the simplified method, which is available if there is insufficient historical data about exercise
patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or
for  each  vesting  tranche  for  awards  with  graded  vesting.  The  midpoint  of  the  vesting  date  and  the  maximum  contractual  expiration  date  is  used  as  the
expected  term  under  this  method.  For  awards  with  multiple  vesting  tranches,  the  times  from  grant  until  the  midpoints  for  each  of  the  tranches  may  be
averaged to provide an overall expected term.

Expected  Volatility.  The  Company  used  an  average  historical  stock  price  volatility  of  a  peer  group  of  publicly  traded  companies  to  be
representative  of  its  expected  future  stock  price  volatility,  as  the  Company  did  not  have  sufficient  trading  history  for  its  common  stock.  For  purposes  of
identifying  these  peer  companies,  the  Company  considered  the  industry,  stage  of  development,  size,  and  financial  leverage  of  potential  comparable
companies. For each grant, the Company measured historical volatility over a period equivalent to the expected term.

Risk-Free  Interest  Rate.  The  risk-free  interest  rate  is  based  on  the  implied  yield  currently  available  on  U.S.  Treasury  zero-coupon  issues  with

remaining terms equivalent to the expected term of a stock award.

79

 
Expected Dividend Rate. The Company has not paid and does not anticipate paying any dividends in the near future. Accordingly, the Company

has estimated the dividend yield to be zero.

Foreign Currency Translation

The  Company  considers  the  functional  currencies  of  its  foreign  subsidiaries  to  be  the  local  currency.  Assets  and  liabilities  recorded  in  foreign
currencies  are  translated  at  the  exchange  rate  as  of  the  balance  sheet  date,  and  costs  and  expenses  are  translated  at  average  exchange  rates  in  effect
during the period. Equity transactions are translated using historical exchange rates. The effects of foreign currency translation adjustments are recorded as
a separate component of accumulated other comprehensive income (loss) in the consolidated balance sheets.

Comprehensive Loss

Comprehensive loss includes all changes in equity (net assets) during the period from nonowner sources. The Company’s comprehensive loss

consists of its net loss, its cumulative translation adjustments, and its unrealized gains or losses on available-for-sale debt securities.

Income Taxes

The Company uses the asset and liability method under ASC Topic 740, Income Taxes, in accounting for income taxes. Deferred tax assets and
liabilities are recognized for the estimated future tax consequences attributable to differences between the consolidated financial statement carrying amounts
of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax expenses or benefits are the result of
changes in the deferred tax assets and liabilities. Valuation allowances are established when necessary to reduce deferred tax assets where it is more likely
than not that the deferred tax assets will not be realized.

ASC Topic 740 clarifies the accounting for uncertainty in income taxes recognized in the financial statements. ASC Topic 740 provides that a tax
benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon audit, including resolutions of
any  related  appeals  or  litigation  processes,  based  on  the  technical  merits  of  the  position.  ASC  Topic  740  also  provides  guidance  on  measurement,
derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

The  Company  recognizes  interest  and  penalties  related  to  unrecognized  tax  benefits  within  the  income  tax  expense  line  in  the  accompanying

consolidated statements of operations. Accrued interest and penalties are included within the related liability line in the consolidated balance sheets.

Net Loss per Share Attributable to Common Stockholders

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of
shares  of  common  stock  outstanding  during  the  period,  without  consideration  of  potentially  dilutive  securities.  Diluted  net  loss  per  share  is  computed  by
dividing  the  net  loss  attributable  to  common  stockholders  by  the  weighted-average  number  of  shares  of  common  stock  and  potentially  dilutive  securities
outstanding for the period. For purposes of the diluted net loss per share calculation, the redeemable convertible preferred stock, convertible preferred stock
warrants, common stock warrants, common stock subject to repurchase, and equity awards are considered to be potentially dilutive securities. Basic and
diluted net loss attributable to common stockholders per share is presented in conformity with the two-class method required for participating securities as
the redeemable convertible preferred stock is considered a participating security. The Company’s participating securities do not have a contractual obligation
to share in the Company’s losses. As such, the net loss is attributed entirely to common stockholders. Because the Company has reported a net loss for the
reporting periods presented, the diluted net loss per common share is the same as basic net loss per common share for those periods.

Cash and Cash Equivalents

Cash  equivalents  consist  of  highly  liquid  investments  with  maturities  at  the  time  of  purchase  of  three  months  or  less.  Cash  equivalents  include
bank demand deposits and money market accounts that invest primarily in cash, U.S. Treasury bills, notes, and other obligations issued or guaranteed as to
principal  and  interest  by  the  U.S.  Government,  its  agencies  or  instrumentalities,  and  repurchase  agreements  secured  by  such  obligations  or  cash.  Cash
equivalents  also  include  commercial  paper,  which  are  marketable  debt  securities  recorded  at  fair  value  and  accounted  for  in  the  same  manner  as  other
marketable debt securities described below.

Short-term Investments

The Company’s investments in marketable debt securities are classified as available-for-sale and recorded at fair value. Investments with original
maturities of greater than three months and remaining maturities of less than one year are classified as short-term investments. Investments with maturities
beyond one year may be classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of
cash  that  is  available  for  current  operations.  Short-term  investments  primarily  consist  of  U.S.  agency  bonds,  commercial  paper,  corporate  bonds,  asset-
backed securities, and U.S. treasuries.

80

 
Unrealized  gains  and  losses  are  included  in  accumulated  other  comprehensive  income  (loss)  in  stockholders’  equity.  Any  discount  or  premium
arising at purchase is accreted or amortized to interest income or expense. Realized gains and losses and declines in fair value, if any, judged to be other
than temporary are reported in other income (expense), net. When securities are sold, any associated unrealized gain or loss initially recorded as a separate
component of stockholders’ equity is reclassified out of stockholders’ equity on a specific-identification basis and recorded in earnings for the period.

The  Company  periodically  evaluates  whether  declines  in  fair  values  of  its  investments  below  their  book  values  are  other-than-temporary.  This
evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company’s ability
and intent to hold the marketable security until a forecasted recovery occurs. Factors considered include quoted market prices, recent financial results and
operating trends, implied values from any recent transactions or offers of investee securities, credit quality of debt instrument issuers, other publicly available
information that may affect the value of the marketable security, duration and severity of the decline in value, and management’s strategy and intentions for
holding  the  marketable  security.  To  date,  the  Company  has  not  recorded  any  impairment  charges  on  its  marketable  securities  related  to  other-than-
temporary declines in market value.

Fair Value Measurements

Financial  assets  and  liabilities  are  recorded  at  fair  value.  Fair  value  is  defined  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to
transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The hierarchy below lists three levels of fair value
based  on  the  extent  to  which  inputs  used  in  measuring  fair  value  are  observable  in  the  market.  Observable  inputs  reflect  market  data  obtained  from
independent sources while unobservable inputs reflect market assumptions made by the reporting entity.

The three-level hierarchy for the inputs to valuation techniques used to measure fair value is briefly summarized as follows:

Level 1 — Unadjusted quoted prices in active markets that are accessible to the reporting entity at the measurement date for identical assets and
liabilities.

Level 2 — Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly for
substantially the full term of the asset or liability. Level 2 inputs include the following:

•

•

•

•

Quoted prices for similar assets and liabilities in active markets.

Quoted prices for identical or similar assets or liabilities in markets that are not active.

Observable inputs other than quoted prices that are used in the valuation of the assets or liabilities (e.g., interest rate and yield curve quotes
at commonly quoted intervals).

Inputs that are derived principally from or are corroborated by observable market data by correlation or other means.

Level 3 — Unobservable inputs for the assets or liabilities (i.e., supported by little or no market activity). Level 3 inputs include management’s own
assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk).

This  hierarchy  requires  the  Company  to  use  observable  market  data,  when  available,  and  to  minimize  the  use  of  unobservable  inputs  when

determining fair value.

Accounts Receivable, Net

Trade accounts receivable are recorded at the invoiced amount and are noninterest bearing. At each reporting period, management reviews all
outstanding  customer  balances  to  determine  if  the  facts  and  circumstances  of  each  customer  relationship  indicate  the  need  for  a  reserve.  A  reserve  is
recorded when it is probable that a loss has been incurred based on past events and conditions existing at the date of the financial statements, and the loss
is reasonably estimated.

Inventory and Other Deferred Costs

Inventory, consisting of supplies used in the Company’s genomic analysis contracts, are valued at the lower of cost or net realizable value. Cost is

determined using actual costs, on a first-in, first-out basis.

Other deferred costs relate to work in process for costs incurred on genomic analysis contracts that have not been completed or recognized as

revenues. Other deferred costs represent materials used in sequencing services, labor, and overhead allocations.

81

 
 
 
 
 
Property and Equipment, Net

Property and equipment are recorded at cost, less accumulated depreciation and amortization, and are depreciated on a straight-line basis over
the estimated useful lives of the related assets, which is generally three to five years for computer equipment, two years for software, three years for furniture
and equipment, and five years for machinery and equipment. Leasehold improvements are amortized over the shorter of the lease term or the estimated
useful life of the related asset. Upon retirement or sale, the cost and related accumulated depreciation and amortization are removed from the consolidated
balance  sheet,  and  the  resulting  gain  or  loss  is  reflected  in  the  consolidated  statements  of  operations.  Maintenance  and  repairs  that  are  not  considered
improvements and do not extend the useful lives of the assets are charged to expense as incurred.

Construction-in-process assets consist primarily of computer equipment and machinery and equipment that have not yet been placed in service.
These  assets  are  stated  at  cost  and  are  not  depreciated.  Once  the  assets  are  placed  into  service,  assets  are  reclassified  to  the  appropriate  asset  class
based on their nature and depreciated in accordance with the useful lives above.

Leases

The  Company  categorizes  leases  with  contractual  terms  longer  than  twelve  months  as  either  operating  or  finance  leases.  Finance  leases  are
generally those leases that allow the Company to substantially utilize or pay for the entire asset over its estimated life. All other leases are categorized as
operating leases. As of December 31, 2020, the Company had no finance leases.

Certain  lease  contracts  include  obligations  to  pay  for  other  services,  such  as  maintenance.  The  Company  elected  to  account  for  these  other

services as a component of the lease (i.e., the Company elected the practical expedient not to separate lease and non-lease components).

Lease liabilities are recognized at the present value of the fixed lease payments, reduced by landlord incentives, using a discount rate based on
the  Company’s  current  borrowing  rate  at  the  lease  commencement  date,  adjusted  for  various  factors  including  level  of  collateralization  and  term  (the
“incremental borrowing rate”), unless the rate implicit in the lease is readily determinable. The current portion of lease liabilities is included in “Accrued and
other current liabilities.” Lease assets are recognized based on the initial present value of the fixed lease payments, reduced by landlord incentives, plus any
direct  costs  from  executing  the  leases  or  lease  prepayments  reclassified  from  “Other  long-term  assets”  upon  lease  commencement.  Lease  assets  are
presented as “Operating lease right-of-use assets” as a long-term asset. Leasehold improvements are capitalized at cost and amortized over the lesser of
their expected useful life or the lease term. Costs associated with operating lease assets are recognized on a straight-line basis within operating expenses
over the term of the lease.

The Company has made an accounting policy election not to recognize right-of-use assets and lease liabilities that arise from leases with a term of

12 months or less. Lease payments are recognized as an expense on a straight-line basis over the lease term.

Recent Accounting Pronouncements

New Accounting Pronouncements Not Yet Adopted

In  June  2016,  the  FASB  issued  Accounting  Standards  Update  (“ASU”)  No.  2016-13,  Financial  Instruments  -  Credit  Losses  (Topic  326):
Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based
on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. The accounting update also made minor
changes  to  the  impairment  model  for  available-for-sale  debt  securities.  In  November  of  2019,  the  FASB  delayed  the  effective  date  for  Smaller  Reporting
Companies to the first quarter of 2023. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and
related  disclosures.  The  Company  will  apply  the  new  guidance  by  means  of  a  cumulative-effect  adjustment  to  the  opening  retained  earnings  as  of  the
beginning of the first reporting period in which the guidance is effective.

JOBS Act Accounting Election

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). Under the JOBS Act,
emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time
as those standards apply to private companies. The Company has irrevocably elected not to avail itself of this exemption from new or revised accounting
standards, and therefore, the Company will be subject to the same new or revised accounting standards as other public companies that are not emerging
growth companies.

Revenues  from  countries  outside  of  the  United  States,  based  on  the  billing  addresses  of  customers,  represented  5%,  4%,  and  3%  of  the

Company’s revenues for the years ended December 31, 2020, 2019 and 2018, respectively.

Contract Assets and Liabilities

Contract assets as of December 31, 2020 were immaterial. The Company had no contract assets as of December 31, 2019.

The Company’s contract liabilities consist of customer deposits in excess of revenues recognized and are presented as current liabilities in the

consolidated balance sheets.

The balance of contract liabilities was $21.0 million and $36.0 million as of December 31, 2020 and 2019, respectively. Revenues recognized in
2020,  2019,  and  2018  that  were  included  in  the  contract  liability  balance  at  the  beginning  of  each  reporting  period  were  $33.8 million,  $35.4  million,  and
$16.0 million, respectively.   

Revenues  allocated  to  remaining  performance  obligations  represent  contracted  revenues  that  have  not  yet  been  recognized  (“contracted  not
recognized revenues”), which include VA MVP contract liabilities and amounts that will be invoiced and recognized as revenues in future periods. Contracted
not recognized revenues were $43.5 million as of December 31, 2020, which the Company expects to recognize as revenues within approximately three
quarters. The Company has elected the optional exemption that allows for the exclusion of contracts with an original expected duration of one year or less.

There have been no realized gains or losses on sales of marketable securities for the periods presented. No security has been in an unrealized
loss position for 12 months or greater. The Company determined that it did have the ability and intent to hold all marketable securities that have been in a
continuous loss position until maturity or recovery. As of December 31, 2020, the Company does not consider any of its marketable debt securities to be
other-than-temporarily impaired.

The  Company’s  marketable  debt  securities  at  December  31,  2020  have  maturities  due  in  one  year  or  less,  except  for  debt  securities  with  an

aggregate cost basis and fair value of $21.1 million that have maturities ranging from 14 months to 23 months.

The Black-Scholes option-pricing model was used to estimate the fair value of the convertible preferred stock warrants at the date of issuance and
at each subsequent consolidated balance sheet date. The fair value of the convertible preferred stock warrants was also estimated at the time of conversion
to  common  stock  warrants  (see  Note  10).  Under  this  option-pricing  model,  convertible  preferred  stock  warrants  were  valued  by  creating  a  series  of  call
options with exercise prices based on the liquidation preferences and

conversion terms of each equity class. The values of the redeemable convertible preferred stock and common stock are inferred by analyzing these options.

The  fair  value  of  each  convertible  preferred  stock  warrant  was  estimated  using  the  Black-Scholes  option-pricing  model  with  the  assumptions
described below. Upon conversion to common stock warrants in the second quarter of 2019 (see Note 10), no further fair value measurements were made.
Therefore, there is no activity with respect to periods after the second quarter of 2019. For the periods indicated, the Company has limited historical volatility
information available, and the expected volatility was based on actual volatility for comparable public companies projected over the expected terms of the
warrants. The Company did not apply a forfeiture rate to the warrants as there is not enough historical information available to estimate such a rate. The risk-
free interest rate was based on the U.S. Treasury yield curve over the expected term of the warrants.

There were no amounts outstanding under financing arrangements as of December 31, 2020 or 2019. Below are descriptions of borrowings that

were outstanding for at least part of either the year ended December 31, 2019 or the year ended December 31, 2018.

Term Loan

In  September  2014,  the  Company  entered  into  a  loan  and  security  agreement  with  Silicon  Valley  Bank  to  borrow  up  to  $3.0  million  under  an
equipment loan to be secured by the equipment financed (the “Term Loan”). On October 3, 2014, the Company borrowed $2.4 million under the Term Loan.
The Term Loan required 12 interest-only payments, followed by 36 equal monthly installments of principal, plus interest, which began on October 3, 2015.

In connection with the Term Loan, the Company issued to the bank a warrant exercisable for ten years from the date of grant to purchase 22,489
shares of the Company’s Series B redeemable convertible preferred stock at an exercise price of $4.60 per share, which was exercised in June 2019 (see
Note 10).

The  estimated  fair  value  of  the  warrants  upon  draw  down  of  $0.1  million  was  based  on  the  Black-Scholes  option-pricing  model.  The  Company
recorded the fair value of the warrant at issuance as a reduction in the debt-carrying value and as a warrant liability. The debt-carrying value reduction was
accreted using the effective interest method as additional interest expense over the contractual period of four years for the Term Loan.

Interest expense for the year ended December 31, 2018 was $0.1 million. On September 30, 2018, the Term Loan was repaid in full.

Convertible Notes

On  June  29,  2017,  the  Company  entered  into  a  convertible  promissory  note  agreement  with  certain  existing  redeemable  convertible  preferred
stockholders  and  third  parties  (collectively,  the  “Investors”)  for  the  issuance  of  convertible  promissory  notes  with  a  face  value  of  $12.2  million  (the
“Convertible Notes”). Under the terms of the Convertible Notes agreement, the Convertible Notes bore interest of 8.00% per annum, with a maturity date of
June 28, 2018. In the event that the Company issued and sold shares of its equity securities (the “Equity Securities”) to Investors on or before the maturity
date  in  an  equity  financing  with  total  proceeds  to  the  Company  of  not  less  than  $10  million  (including  the  conversion  of  the  Convertible  Notes  or  other
convertible securities issued for capital raising

purposes)  (a  “Qualified  Financing”),  then  the  outstanding  principal  amount  of  the  Convertible  Notes  and  any  unpaid  accrued  interest  would  have
automatically converted in whole without any further action by the holder into such Equity Securities sold in the Qualified Financing at a conversion price
equal to the price paid per share for Equity Securities by the Investors in the Qualified Financing multiplied by 0.8. If the Company consummated a change of
control while the Convertible Notes remained outstanding, the Company would have repaid the holders in cash an amount equal to 150% of the outstanding
principal amount of the Convertible Notes, plus any unpaid accrued interest on the original principal. The Convertible Notes had customary events of default.

Certain conversion and redemption features of the Convertible Notes met the requirements for separate accounting and were accounted for as a
single, compound derivative instrument. The compound derivative instrument was recorded at fair value at inception and was subject to remeasurement to
fair value at each consolidated balance sheet date, with any changes in fair value recognized in the consolidated statements of operations as other income
(expense), net. The estimated fair value of the compound derivative instrument was $0.5 million at issuance and was recorded as a reduction in the carrying
value of the Convertible Notes and as a single, compound derivative liability. The Convertible Notes carrying value reduction was accreted using the effective
interest  method  as  interest  expense  over  the  Convertible  Notes  contractual  period  of  one  year.  The  Convertible  Notes  had  an  effective  interest  rate  of
12.69% per year.

On May 31, 2018, the original maturity date for the Convertible Notes was extended to June 28, 2019 (previously June 28, 2018). The maturity
date extension was deemed substantial and was accounted for as a debt extinguishment. In connection with the debt extinguishment on May 31, 2018, the
fair value of the Convertible Notes was allocated between the carrying amount of the Convertible Notes and accrued interest of $13.1 million, a compound
derivative asset of $0.6 million, and an equity component of $3.9 million, which was credited to additional paid-in capital within the consolidated statements
of redeemable convertible preferred stock and stockholders’ equity (deficit). A $3.3 million loss on debt extinguishment was also recorded in the consolidated
statements of operations. The new carrying value of the Convertible Notes was accreted using the effective interest method as interest expense over the
new contractual period of 1.1 years.

On  August  20,  2018,  the  maturity  date  for  the  Convertible  Notes  was  extended  to  September  20,  2018  (previously  June  28,  2019).  The  term
change was deemed substantial and was accounted for as a debt extinguishment. In connection with the debt extinguishment on August 20, 2018, the fair
value of the Convertible Notes was allocated between the new carrying amount of the Convertible Notes and accrued interest of $13.4 million, and an equity
component of $0.8 million, which resulted in a credit to additional paid-in capital. Upon modification, the compound derivative asset was eliminated. A $0.8
million  loss  on  debt  extinguishment  was  also  recorded  in  the  consolidated  statements  of  operations.  The  new  carrying  value  of  Convertible  Notes  was
accreted using the effective interest method as interest expense over the new contractual period of one month.

On  September  20,  2018,  upon  the  maturity  of  the  Convertible  Notes,  the  carrying  amount,  including  accrued  interest  of  $13.4  million,  was
converted into 1,667,997 shares of the Company’s Series C redeemable convertible preferred stock at a conversion price equal to $8.052 per share. No gain
or loss was recorded on the conversion.

The Convertible Notes interest expense for the year ended December 31, 2018 was $0.9 million.

Revolving Loan

In June 2017, the Company entered into a $10.0 million revolving loan and security agreement (the “Revolving Loan”) with TriplePoint Capital LLC
(“TriplePoint”).  The  Company  borrowed  $5.0  million  under  the  Revolving  Loan.  Borrowings  under  the  Revolving  Loan  bear  an  interest  rate  of  prime,  plus
6.75%. The Revolving Loan also has a 5.5% end of term loan payment on the highest outstanding principal amount. The Revolving Loan requires monthly
interest-only payments until the maturity date. The Revolving Loan’s original maturity date was December 31, 2018, and in December 2018 the maturity date
was further extended until March 22, 2019. Upon determining that the change in cash flows between the previous and revised credit facility was not greater
than 10%, the Company accounted for the transaction as a debt modification.

In connection with the Revolving Loan, the Company issued to TriplePoint a warrant to purchase up to 62,096 shares of the Company’s Series C

redeemable convertible preferred stock at an exercise price of $8.052 per share, which was exercised in August 2020 (see Note 10).

The  estimated  fair  value  of  the  warrant  upon  draw  down  of  $0.1  million  was  based  on  the  Black-Scholes  option-pricing  model.  The  Company
recorded the fair value of the warrant at issuance as a reduction in the debt-carrying value and as a warrant liability. The debt-carrying value reduction was
accreted using the effective interest method as additional interest expense over the contractual period of 1.5 years for the Revolving Loan.

The  Revolving  Loan  had  an  effective  interest  rate  of  19.22%  per  year.  Interest  expense  was  $0.2  million  and  $0.9  million  for  the  years  ended

December 31, 2019 and 2018, respectively. On March 22, 2019, this Revolving Loan was repaid in full.

Growth Capital Loan

On March 22, 2019, the Company entered into a growth capital loan (the “Growth Capital Loan”) with TriplePoint to provide for a $20.0 million
growth capital loan facility and had drawn down the full $20.0 million available under the facility. The Company used $5.1 million of the Growth Capital Loan
to repay, in its entirety, all amounts outstanding under the Revolving Loan. Borrowings under the Growth Capital Loan bore interest at a floating rate of prime,
plus 5.00% for borrowings up to $15.0 million and the prime rate plus 6.50% for borrowings greater than $15.0 million. Under the agreement, the Company
was required to make monthly interest-only payments through April 1, 2020 and was required to make 36 equal monthly payments of principal, plus accrued
interest, from April 1, 2020 through March 1, 2023, when all unpaid principal and interest was to become due and payable. The agreement allowed voluntary
prepayment of all, but not part, of the outstanding principal at any time prior to the maturity date, subject to a prepayment fee of 1.00% of the outstanding
balance if prepaid in months one through 12 of the loan term. In addition to the final payment, the Company paid an amount equal to 2.75% of each principal
amount drawn under this Growth Capital Loan facility.

In  connection  with  the  Growth  Capital  Loan,  the  Company  issued  a  warrant  to  purchase  65,502  shares  of  common  stock  to  TriplePoint  at  an
exercise price of $9.16 per share, which was exercised in August 2020 (see Note 11). The Company recorded the issuance-date fair value of the warrant of
$0.6 million and fees paid to TriplePoint of $0.3 million as a debt discount, which was amortized over the term of the Growth Capital Loan using the effective
interest rate method.

Upon  issuance,  the  Growth  Capital  Loan  had  an  effective  interest  rate  of  15.23%  per  year.  Interest  expense  for  the  year  ended  December  31,

2019 was $1.0 million.

On August 14, 2019, the Company paid off the Growth Capital Loan in its entirety. In connection with this debt repayment, the Company recorded

a $1.7 million loss on extinguishment of debt in the consolidated statements of operations.

Note 7. Leases

In February 2015, the Company entered into a noncancelable operating lease for approximately 31,280 square feet of space used for its current
laboratory  and  corporate  headquarters.  In  April  2020,  the  Company  extended  the  lease  term.  The  lease  expires  on  November  30,  2027  and  includes  an
option to extend the term for a period of three years with rent payments equal to then current fair market rental for the space. The Company determined the
extension option is not reasonably certain to be exercised. The lease contains a leasehold improvement incentive and escalating rent payments.

In August 2019, the Company entered into a noncancelable operating lease for a co-located data center space. The lease expires on August 31,
2022  and  includes  an  option  to  extend  the  term  for  a  period  of  three  years  immediately  following  the  expiration  of  the  term  with  rent  payments  to  be
negotiated upon such a renewal. The Company determined the extension is not reasonably certain to be exercised. In April 2020, the lease was modified to
increase the data center space available for the Company’s use for the remainder of the lease term.

Operating lease cost for the years ended December 31, 2020 and 2019 was $2.3 million and $1.1 million, respectively.

As of December 31, 2020, the Company’s operating leases had a weighted-average remaining lease term of 6.4 years and a weighted-average
discount  rate  of  10.7%.  The  Company’s  discount  rates  are  based  on  estimates  of  its  incremental  borrowing  rate,  as  the  discount  rates  implicit  in  the
Company’s lease cannot be readily determined. Future lease payments under operating leases as of December 31, 2020 were as follows (in thousands):

Immediately prior to the closing of the Company’s IPO, all shares of the Company’s then-outstanding Redeemable Convertible Preferred Stock, as
shown in the table above, automatically converted on a one-for-one basis into an aggregate of 18,474,703 shares of common stock. The Reverse Stock Split
was effected on a holder-by-holder basis with no fractional shares issued, which resulted in 39 fewer shares of common stock issued as compared to the
amounts shown in the above table.

Note 9. Stock-Based Compensation

2011 Equity Incentive Plan

In 2011, the Company established its 2011 Equity Incentive Plan (the “2011 Plan”) that provided for the granting of stock options to employees
and nonemployees of the Company. Under the 2011 Plan, the Company had the ability to issue incentive stock options (“ISOs”), nonstatutory stock options
(“NSOs”), stock appreciation rights, restricted stock awards, and restricted stock unit awards (“RSUs”). Options under the 2011 Plan could be granted for
periods of up to 10 years. The ISOs could be granted at a price per share not less than the fair value at the date of grant.

For stock option grants issued prior to December 31, 2015, the Company allowed employees to exercise options granted under the 2011 Plan
prior  to  vesting  (early  exercise  of  stock  options).  The  unvested  shares  were  subject  to  the  Company’s  repurchase  rights  at  the  original  purchase  price.
Initially,  the  proceeds  were  recorded  as  an  accrued  liability  from  the  early  exercise  of  stock  options  and  reclassified  to  common  stock  as  the  Company’s
repurchase rights lapsed. There were no unvested shares subject to the Company’s repurchase rights as of December 31, 2020 and 2019.

2019 Equity Incentive Plan

The Company’s board of directors adopted and the Company’s stockholders approved the 2019 Equity Incentive Plan (the “2019 Plan”) in May
2019 and June 2019, respectively. The 2019 Plan became effective in June 2019 in connection with the Company’s IPO, and no further grants will be made
under  the  2011  Plan.  Shares  reserved  and  remaining  available  for  issuance  under  the  2011  Plan  were  added  to  the  2019  Plan  reserve  upon  its
effectiveness.

The 2019 Plan provides for the grant of ISOs, NSOs, stock appreciation rights, restricted stock awards, RSUs, performance-based stock awards,
and other forms of equity compensation. Additionally, the 2019 Plan provides for the grant of performance cash awards. ISOs may be granted only to the
Company’s employees and to any of the Company’s parent or subsidiary corporation’s employees. All other awards may be granted to employees, including
officers, and to non-employee directors and consultants of the Company and any of the Company’s affiliates. The exercise price of a stock option generally
cannot be less than 100% of the fair market value of the Company’s common stock on the date of grant. Options under the 2019 Plan may be granted for
periods of up to 10 years.

2020 Inducement Plan

The Compensation Committee of the Company’s board of directors adopted the 2020 Inducement Plan (the “Inducement Plan”) in May 2020,
which became effective upon adoption. The Inducement Plan was adopted without stockholder approval, as permitted by the Nasdaq Stock Market rules.
The Inducement Plan provides for the grant of equity-based awards, including NSOs, stock appreciation rights, restricted stock awards, RSUs, performance-
based stock awards, and other forms of equity compensation, and its terms are substantially similar to the stockholder-approved 2019 Plan. In accordance
with  relevant  Nasdaq  Listing  Rules,  awards  under  the  Inducement  Plan  may  only  be  made  to  individuals  not  previously  employees  or  non-employee
directors of the

Company  (or  following  such  individuals’  bona  fide  period  of  non-employment  with  the  Company),  as  an  inducement  material  to  the  individuals  entry  into
employment with the Company.

2019 Employee Stock Purchase Plan

The Company’s board of directors adopted and the Company’s stockholders approved the 2019 Employee Stock Purchase Plan (the “ESPP”) in
May  2019  and  June  2019,  respectively.  Subject  to  any  plan  limitations,  the  ESPP  allows  eligible  employees  to  contribute,  normally  through  payroll
deductions, up to 15% of their earnings for the purchase of the Company’s common stock at a discounted price per share. The price at which common stock
is  purchased  under  the  ESPP  is  equal  to  85%  of  the  fair  market  value  of  the  Company’s  common  stock  on  the  first  or  last  day  of  the  offering  period,
whichever is lower. The ESPP provides for separate six-month offering periods beginning on May 1 and November 1 of each year.

Shares  of  common  stock  available  for  issuance  under  the  Company’s  equity  incentive  plans  at  December  31,  2020  and  December  31,  2019

were as follows:

Reserved for issuance upon exercise of options outstanding under the 2011 Plan
Reserved for issuance upon exercise or settlement of awards outstanding under the 2019 Plan
Reserved and available for issuance under the 2019 Plan
Reserved for issuance upon exercise or settlement of awards outstanding under the Inducement Plan

Options granted to new hires generally vest over a four-year period, with 25% vesting at the end of one year and the remaining vesting monthly

thereafter. Options granted as merit awards generally vest monthly over a three- or four-year period.

The aggregate intrinsic value of unexercised stock options is calculated as the difference between the closing price of the Company’s common
stock  of  $36.61  on  December  31,  2020  and  the  exercise  prices  of  the  underlying  stock  options.  Out-of-the  money  stock  options  are  excluded  from  the
aggregate intrinsic value.

The weighted-average grant date fair value of options granted was $7.17, $8.00, and $5.68 per share for the years ended December 31, 2020,
2019,  and  2018,  respectively.  As  of  December  31,  2020,  the  unrecognized  stock-based  compensation  of  unvested  options  was  $13.3  million,  which  is
expected to be recognized over a weighted-average period of 2.7 years.

Valuation of Stock Options

The  Company  estimated  the  fair  value  of  stock  options  (excluding  performance-based  stock  options  discussed  below)  using  the  Black-Scholes
option-pricing model. The fair value of stock options is recognized on a straight-line basis over the requisite service periods of the awards. The fair value of
stock options was estimated using the following weighted-average assumptions:

Volatility
Risk-free interest rate
Dividend yield

Pursuant  to  the  2019  Plan,  in  March  2020,  the  Company’s  board  of  directors  granted  the  Company’s  Chief  Executive  Officer  a  performance-
based stock option (“PSO”) to purchase 421,000 shares of common stock. The PSO was subject to the Chief Executive Officer’s continued service to the
Company through the date of vesting and, if the performance condition were not met within 10 years from the date of grant, the PSO would be canceled. The
shares  subject  to  the  PSO  would  vest  in  full  if  the  Company’s  average  market  capitalization  is  equal  to  or  greater  than  $1  billion  over  a  30  calendar  day
period. Upon a change in control, the vesting of the shares subject to the PSO would accelerate on a pro rata basis based on the price per share in such
change in control transaction multiplied by the price per share at such time divided by $1 billion, with up to 100% of the shares eligible for such accelerated
vesting.

market capitalization was equal to or greater than $1 billion over a 30 calendar day period and the PSO vested in full. As of December 31, 2020, there is no

The  Company  granted  RSUs  to  employees  to  receive  shares  of  the  Company’s  common  stock.  The  RSUs  awarded  are  subject  to  each
individual’s  continued  service  to  the  Company  through  each  applicable  vesting  date.  RSUs  granted  to  new  hires  generally  vest  annually  over  a  four-year
period.  RSUs  granted  as  merit  awards  generally  vest  semi-annually  over  a  three-year  period,  or  in  some  cases  quarterly  over  a  three-year  period.  The
Company accounted for the fair value of the RSUs using the closing market price of the Company’s common stock on the date of grant.

The  aggregate  fair  value  of  unvested  RSUs  is  calculated  using  the  closing  price  of  the  Company’s  common  stock  of  $36.61  on  December  31,
2020. As of December 31, 2020, the unrecognized stock-based compensation cost of unvested RSUs was $5.9 million, which is expected to be recognized
over a weighted-average period of 2.9 years.

The Company’s default tax withholding method for RSUs is the sell-to-cover method, in which shares with a market value equivalent to the tax
withholding obligation are sold on behalf of the holder of the RSUs upon vesting and settlement to cover the tax withholding liability and the cash proceeds
from such sales are remitted by the Company to taxing authorities.

ESPP Activity and Valuation

During  the  years  ended  December  31,  2020  and  2019,  164,164  and  77,684  shares  of  common  stock  were  purchased,  respectively,  under  the
ESPP. The following assumptions were used to calculate the stock-based compensation for each stock purchase right granted under the ESPP during 2020:
expected term of 0.5 years; expected volatility of 65.15 – 102.10%; risk-free interest rate of 0.1%; and a zero dividend yield. The resulting grant-date fair
values were $8.12 and $4.29. The following assumptions were used to calculate the stock-based compensation for each stock purchase right granted under
the ESPP during 2019: expected term of 0.4 – 0.5 years; expected volatility of 59.06 – 59.91%; risk-free interest rate of 1.6% - 2.1%; and a zero dividend
yield. The resulting grant-date fair values were $3.48 and $5.01.

Note 10. Redeemable Convertible Preferred Stock Warrants

In  September  2014,  in  connection  with  the  Term  Loan  (see  Note  6),  the  Company  issued  a  warrant  to  purchase  22,489  shares  of  its  Series  B
redeemable convertible preferred stock at an exercise price of $4.60 per share. In June 2017, as additional consideration for the Revolving Loan (see Note
6), the Company issued a warrant to purchase up to 62,096 shares of its Series C redeemable convertible preferred stock at an exercise price of $8.052.

At  initial  recognition,  the  convertible  preferred  stock  warrants  were  recorded  at  their  estimated  fair  values  ($0.1  million  each  initially)  and  were
subject to remeasurement at each consolidated balance sheet date, with changes in fair value recognized as a component of net income. See Note 5 for the
estimated fair values and changes in fair values relating to periods presented.

Immediately prior to the closing of the Company’s IPO, the redeemable convertible preferred stock warrants automatically converted to common
stock warrants. As a result of the automatic conversion of the redeemable convertible preferred stock warrants to common stock warrants, the Company
revalued  the  redeemable  convertible  preferred  stock  warrants  as  of  the  completion  of  the  IPO  and  reclassified  the  outstanding  preferred  stock  warrant
liability  balance  to  additional  paid-in  capital  with  no  further  remeasurements  as  the  common  stock  warrants  are  now  deemed  permanent  equity.  The  fair
value transferred to additional paid-in capital was $2.1 million.

Subsequent to the conversion to a common stock warrant and before the end of the Company’s second quarter ended June 30, 2019, the warrant
for  22,489  shares  was  exercised.  The  Company  issued  19,069  shares  of  common  stock  as  the  warrant  allowed  a  net  share  settlement.  Separately,  the
warrant for 62,096 shares issued in June 2017 was exercised in August 2020. The Company issued 40,357 shares of common stock as the warrant allowed
for a net share settlement.

Note 11. Common Stock Warrants

In  connection  with  the  sale  of  Series  A  redeemable  convertible  preferred  stock  in  August  2011,  the  Company  issued  a  warrant  to  purchase
188,643  shares  of  common  stock  to  an  investor  who  purchased  Series  A  redeemable  convertible  preferred  stock  in  August  2011  at  an  exercise  price  of
$0.04  per  share.  The  Company  recorded  the  issuance-date  fair  value  of  the  warrant  of  $0.1  million  in  equity  as  the  warrant  met  all  criteria  for  equity
classification. The common stock warrant was exercised in June 2019 prior to the Company’s IPO and is no longer outstanding.

In connection with the Growth Capital Loan agreement (see Note 6), the Company issued a warrant to purchase 65,502 shares of common stock
to  the  lender  at  an  exercise  price  of  $9.16  per  share.  The  Company  recorded  the  issuance-date  fair  value  of  the  warrant  of  $0.6  million  in  equity  as  the
warrant met all criteria for equity classification. The warrant was exercised in September 2020 and is no longer outstanding. The Company issued 39,415
shares of common stock as the warrant allowed for a net share settlement.

Note 12. Commitments and Contingencies

Contingencies

The Company is subject to claims and assessments from time to time in the ordinary course of business. Accruals for litigation and contingencies
are reflected in the consolidated financial statements based on management’s assessment, including the advice of legal counsel, of the expected outcome of
litigation or other dispute resolution proceedings and/or the expected resolution of contingencies. Liabilities for estimated losses are accrued if the potential
losses from any claims or legal proceedings are considered probable and the amounts can be reasonably estimated. Significant judgment is required in both
the determination of probability of loss and the determination as to whether the amount can be reasonably estimated. Accruals are based only on information
available at the time of the assessment due to the uncertain nature of such matters. As additional information becomes available, management reassesses
potential liabilities related to pending claims and litigation and may revise its previous estimates, which could materially affect the Company’s consolidated
results of operations in a given period. As of December 31, 2020, the Company was not involved in any material legal proceedings.

Indemnification

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and
provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against
the Company in the future, but that have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to
its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.

Note 13. Net Loss per Share Attributable to Common Stockholders

Basic  net  loss  per  share  is  computed  by  dividing  the  net  loss  by  the  weighted-average  number  of  common  shares  outstanding  for  the  period.
Because the Company reported a net loss for all periods presented, the number of shares used to calculate diluted net loss per common share is the same
as the number of shares used to calculate basic net loss per common share for those periods presented because the potentially dilutive shares would have
been antidilutive if included in the calculation.

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), which includes several
U.S. income tax provisions related to, among other things, net operating loss carrybacks, alternative minimum tax credits, modifications to interest expense
limitations, and an option to defer payroll tax payments for a limited period. Based on the guidance in the CARES Act, the Company deferred the payment of
$0.7  million  of  certain  payroll  taxes  to  be  paid  in  the  future.  The  other  provisions  of  the  CARES  Act  did  not  have  a  significant  impact  on  the  Company’s
consolidated financial statements.

Deferred Tax Assets and Liabilities

Deferred  income  taxes  reflect  the  net  tax  effects  of  loss  and  credit  carryforwards  and  temporary  differences  between  the  carrying  amounts  of
assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax
assets for federal and state income taxes are as follows (in thousands):

Deferred tax assets:

Net operating loss carryforwards
Research and development credits
Deferred revenue
Accruals
Stock-based compensation
Operating lease liabilities
Other intangibles
Other

Total gross deferred tax assets
Less: Valuation allowance

Realization  of  deferred  tax  assets  is  dependent  upon  future  earnings,  if  any,  the  timing  and  amount  of  which  are  uncertain.  Because  of  the
Company’s lack of U.S. earnings history, the net U.S. deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased
by $16.8 million and $7.6 million during the years ended December 31, 2020 and 2019, respectively.

Net Operating Loss and Tax Credit Carryforwards

As of December 31, 2020, the Company had a net operating loss carryforward for federal income tax purposes of approximately $159.2 million,
portions  of  which  will  begin  to  expire  in  2031.  The  Company  had  a  total  state  net  operating  loss  carryforward  of  approximately  $112.7  million,  which  will
begin to expire in 2031. Utilization of some of the federal and state net operating loss and credit carryforwards are subject to annual limitations due to the
“change in ownership” provisions of the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitations may result in the
expiration of net operating losses and credits before utilization.

As of December 31, 2020, the Company has federal credits of approximately $4.2 million, which will begin to expire in 2031 and state research

credits of approximately $4.3 million, which have no expiration date. These tax credits are subject to the same limitations discussed above.

Unrecognized Tax Benefits

The  Company  has  incurred  net  operating  losses  since  inception  and  does  not  have  any  significant  unrecognized  tax  benefits.  The  Company’s
policy  is  to  include  interest  and  penalties  related  to  unrecognized  tax  benefits,  if  any,  within  the  provision  for  taxes  in  the  consolidated  statements  of
operations. If the Company is eventually able to recognize its uncertain positions, the effective tax rate would be reduced. The Company currently has a full
valuation  allowance  against  its  net  deferred  tax  asset,  which  would  impact  the  timing  of  the  effective  tax  rate  benefit  should  any  of  these  uncertain  tax
positions be favorably settled in the future. Any adjustments to the Company’s uncertain tax positions would result in an adjustment of net operating loss or
tax credit carryforwards rather than resulting in a cash outlay.

The  Company  files  U.S.  federal  income  tax  returns  and  various  state  income  tax  returns.  Because  of  net  operating  losses  and  research  credit

carryovers, substantially all the Company’s tax years remain open to examination.

The Company has the following activity relating to unrecognized tax benefits (in thousands):

Although  it  is  reasonably  possible  that  certain  unrecognized  tax  benefits  may  increase  or  decrease  within  the  next  12  months  due  to  tax
examination changes, settlement activities, expirations of statute of limitations, or the impact on recognition and measurement considerations related to the
results of published tax cases or other similar activities, the Company does not anticipate any significant changes to unrecognized tax benefits over the next
12 months. During the years ended December 31, 2020, 2019, and 2018, no interest or penalties were required to be recognized relating to unrecognized
tax benefits.

Note 15. Subsequent Events

Subsequent  to  the  annual  period  ended  December  31,  2020  covered  by  this  Annual  Report,  on  January  29,  2021,  we  completed  a  follow-on
offering in which we issued and sold 3,950,000 shares of common stock at a public offering price of $38.00 per share. We received net proceeds of $141.1
million after deducting underwriting discounts and commissions. The underwriters of the offering exercised their option to purchase an additional 592,500
shares  shortly  thereafter,  resulting  in  additional  net  proceeds  to  us  of  $21.2  million  after  deducting  underwriting  discounts  and  commissions.  In  total,  we
raised  net  proceeds  of  $162.3  million  after  deducting  underwriting  discounts  and  commissions.  We  also  incurred  an  estimated  $0.4  million  of  offering
expenses, including legal, accounting, printing and other offering-related costs.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors of Personalis, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Personalis, Inc. and subsidiaries (the "Company") as of December 31, 2020 and 2019,
the related consolidated statements of operations, comprehensive loss, redeemable convertible preferred stock and stockholders' equity (deficit), and cash
flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the "financial statements"). In our
opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the
results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles
generally accepted in the United States of America.

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 Public Company Accounting Oversight Board (United States) (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. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial
reporting. Accordingly, we express no such opinion.

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.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer, or CEO, and chief financial officer, or CFO, has evaluated the effectiveness
of  our  disclosure  controls  and  procedures  (as  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Securities  Exchange  Act  of  1934,  as  amended,  or
Exchange Act), as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, our CEO and CFO have concluded that
as of December 31, 2020, our disclosure controls and procedures were effective in providing reasonable assurance that information required to be disclosed
by us in reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the
Securities  and  Exchange  Commission’s  rules  and  forms,  and  that  such  information  is  accumulated  and  communicated  to  our  management,  including  our
CEO and CFO, as appropriate to allow timely decisions regarding required disclosures.

Management Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of
the  1934  Act.  Management  has  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2020  based  on  criteria
established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. As a
result  of  this  assessment,  management  concluded  that,  as  of  December  31,  2020,  our  internal  control  over  financial  reporting  was  effective  in  providing
reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with
generally accepted accounting principles in the United States of America.

Our independent registered accounting firm is not required to issue an attestation report on our internal control over financial reporting for so long

as we qualify as an “emerging growth company,” as defined under the JOBS Act.

Changes in Internal Control

None.

Limitations on Controls

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving
their objectives as specified above. Management does not expect, however, that our disclosure controls and procedures or our internal control over financial
reporting will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and
can provide only reasonable, not absolute, assurance that its objectives will be met. Further, 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 the Company have been detected.

DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES
EXCHANGE ACT OF 1934

Exhibit 4.1

Personalis,  Inc.  (“we,”  “our,”  “us,”  or  the  “Company”)  has  one  class  of  securities  registered  under  Section  12  of  the  Securities  Exchange  Act  of  1934,  as
amended  (the  “Exchange  Act”):  our  common  stock.  The  following  summary  of  the  terms  of  our  common  stock  is  based  upon  our  amended  and  restated
certificate of incorporation and our amended and restated bylaws. This summary does not purport to be complete and is subject to, and is qualified in its
entirety by express reference to, the applicable provisions of our amended and restated certificate of incorporation, our amended and restated bylaws, and
the  amended  and  restated  investor  rights  agreement  (the  “IRA”).  We  encourage  you  to  read  our  amended  and  restated  certificate  of  incorporation,  our
amended and restated bylaws, the IRA, and the applicable provisions of the Delaware General Corporation Law (the “DGCL”) for more information.

DESCRIPTION OF CAPITAL STOCK

General

Our  authorized  capital  stock  consists  of  210,000,000  shares,  all  with  a  par  value  of  $0.0001  per  share,  of  which:  200,000,000  shares  are  designated  as
common stock and 10,000,000 shares are designated as preferred stock.

Common Stock

Holders  of  our  common  stock  are  entitled  to  one  vote  for  each  share  held  on  all  matters  submitted  to  a  vote  of  stockholders,  including  the  election  of
directors, and do not have cumulative voting rights. Accordingly, the holders of a majority of the outstanding shares of common stock entitled to vote in any
election of directors can elect all of the directors standing for election, if they so choose, other than any directors that holders of any preferred stock we may
issue may be entitled to elect. Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of common stock are entitled
to  receive  ratably  those  dividends,  if  any,  as  may  be  declared  by  the  board  of  directors  out  of  legally  available  funds.  In  the  event  of  our  liquidation,
dissolution, or winding up, the holders of common stock will be entitled to share ratably in the assets legally available for distribution to stockholders after the
payment of or provision for all of our debts and other liabilities, subject to the prior rights of any preferred stock then-outstanding. Holders of common stock
have  no  preemptive  or  conversion  rights  or  other  subscription  rights  and  there  are  no  redemption  or  sinking  funds  provisions  applicable  to  the  common
stock. All outstanding shares of common stock are duly authorized, validly issued, fully paid, and nonassessable. All authorized but unissued shares of our
common  stock  are  available  for  issuance  by  our  board  of  directors  without  any  further  stockholder  action,  except  as  required  by  the  listing  standards  of
Nasdaq. The rights, preferences, and privileges of holders of common stock are subject to and may be adversely affected by the rights of the holders of
shares of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Our  board  of  directors  may,  without  further  action  by  our  stockholders,  fix  the  rights,  preferences,  privileges  and  restrictions  of  up  to  an  aggregate  of
10,000,000 shares of redeemable convertible preferred stock in one or more series and authorize their issuance. These rights, preferences, and privileges
could  include dividend rights, conversion rights,  voting  rights,  terms  of  redemption,  liquidation  preferences,  sinking  fund  terms,  and  the  number  of  shares
constituting  any  series  or  the  designation  of  such  series,  any  or  all  of  which  may  be  greater  than  the  rights  of  our  common  stock.  The  issuance  of  our
redeemable  convertible  preferred  stock  could  adversely  affect  the  voting  power  of  holders  of  our  common  stock,  and  the  likelihood  that  such  holders  will
receive  dividend  payments  and  payments  upon  liquidation.  In  addition,  the  issuance  of  preferred  stock  could  have  the  effect  of  delaying,  deferring,  or
preventing a change of control or other corporate action.

Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws

Some provisions of Delaware law, our amended and restated certificate of incorporation, and our amended and restated bylaws contain provisions that could
make the following transactions more difficult: an acquisition of us by means of a tender offer; an acquisition of us by means of a proxy contest or otherwise;
or  the  removal  of  our  incumbent  officers  and  directors.  It  is  possible  that  these  provisions  could  make  it  more  difficult  to  accomplish  or  could  deter
transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions which provide for payment of
a premium over the market price for our shares.

These  provisions,  summarized  below,  are  intended  to  discourage  coercive  takeover  practices  and  inadequate  takeover  bids.  These  provisions  are  also
designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We

 
 
 
 
 
 
 
 
 
 
 
 
 
 
believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire
or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their
terms.

Stockholder Meetings

Our amended and restated bylaws provide that a special meeting of stockholders may be called only by our chairman of the board, chief executive officer or
president, or by a resolution adopted by a majority of our board of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals to be brought before a stockholder meeting
and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the
board of directors.

Our amended and restated certificate of incorporation and amended and restated bylaws eliminate the right of stockholders to act by written consent without
a meeting.

Elimination of Stockholder Action by Written Consent

Staggered Board

Our board of directors is divided into three classes. The directors in each class will serve for a three-year term, one class being elected each year by our
stockholders.  This  system  of  electing  and  removing  directors  may  tend  to  discourage  a  third  party  from  making  a  tender  offer  or  otherwise  attempting  to
obtain control of us, because it generally makes it more difficult for stockholders to replace a majority of the directors.

Removal of Directors

Our amended and restated certificate of incorporation provides that no member of our board of directors may be removed from office by our stockholders
except  for  cause  and,  in  addition  to  any  other  vote  required  by  law,  upon  the  approval  of  not  less  than  two-thirds  of  the  total  voting  power  of  all  of  our
outstanding voting stock then entitled to vote in the election of directors.

Our  amended  and  restated  certificate  of  incorporation  does  not  permit  stockholders  to  cumulate  their  votes  in  the  election  of  directors.  Accordingly,  the
holders of a majority of the outstanding shares of our common stock entitled to vote in any election of directors can elect all of the directors standing for
election, if they choose, other than any directors that holders of our preferred stock may be entitled to elect.

Stockholders Not Entitled to Cumulative Voting

Delaware Anti-Takeover Statute

We are subject to Section 203 of the DGCL, which prohibits persons deemed to be “interested stockholders” from engaging in a “business combination” with
a publicly held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or
the  transaction  in  which  the  person  became  an  interested  stockholder  was,  approved  in  a  prescribed  manner  or  another  prescribed  exception  applies.
Generally,  an  “interested  stockholder”  is  a  person  who,  together  with  affiliates  and  associates,  owns,  or  within  three  years  prior  to  the  determination  of
interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock
sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with
respect to transactions not approved in advance by the board of directors.

Choice of Forum

Our  amended  and  restated  certificate  of  incorporation  provides  that,  unless  we  consent  in  writing  to  the  selection  of  an  alternative  forum,  the  Court  of
Chancery of the State of Delaware will be the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (1)
any derivative action or proceeding brought on our behalf; (2) any action asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our
directors, officers, employees, or agents to us or our stockholders; (3) any action asserting a claim against us arising pursuant to any provision of the DGCL
or our certificate of incorporation or bylaws; (4) any action to interpret, apply, enforce or determine the validity of our certificate of incorporation or bylaws; or
(5) any action asserting a claim governed by the internal affairs doctrine. This provision would not apply to suits brought to enforce a duty or liability created
by the Exchange Act or any

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
other  claim  for  which  the  U.S.  federal  courts  have  exclusive  jurisdiction.  Our  amended  and  restated  certificate  of  incorporation  further provides  that  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,  subject  to  and  contingent  upon  a  final  adjudication  in  the  State  of  Delaware  of  the  enforceability  of  such  exclusive  forum  provision.  Our
amended  and  restated  certificate  of  incorporation  also provides  that  any  person  or  entity  purchasing  or  otherwise  acquiring  any  interest  in  shares  of  our
capital stock will be deemed to have notice of and to have consented to these choice of forum provisions. It is possible that a court of law could rule that the
choice of forum provisions to be contained in our amended and restated certificate of incorporation are inapplicable or unenforceable if they are challenged
in a proceeding or otherwise.

Amendment of Charter Provisions

The amendment of any of the above provisions, except for the provision making it possible for our board of directors to issue preferred stock, would require
approval by holders of at least two-thirds of the total voting power of all of our outstanding voting stock.

The  provisions  of  Delaware  law,  our  amended  and  restated  certificate  of  incorporation,  and  our  amended  and  restated  bylaws  could  have  the  effect  of
discouraging  others  from  attempting  hostile  takeovers  and,  as  a  consequence,  they  may  also  inhibit  temporary  fluctuations  in  the  market  price  of  our
common stock that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the
composition of our board and management. It is possible that these provisions could make it more difficult to accomplish transactions that stockholders may
otherwise deem to be in their best interests.

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A.

Transfer Agent and Registrar

Our common stock is currently listed on The Nasdaq Global Market under the symbol “PSNL.”

Plan)) and an exercise price per share equal to 100% of the Fair Market Value (as defined in the Plan) of a share of the Company’s common stock on the
date of grant.  

(a)

Automatic Equity Grants.  

(i)

Initial Grant for New Directors.  Without any further action of the Board, each person who is elected or appointed for
the first time to be a Non-Employee Director will automatically, upon the date of his or her initial election or appointment to be a Non-Employee Director, be
granted:  (x)  a  Nonstatutory  Stock  Option  to  purchase  a  number  of  shares  of  the  Company’s  common  stock  (the  “Initial  Option  Grant”)  with  a  value  of
$100,000 determined using Black-Scholes’ valuation methodology based on the average closing price of the Company’s common stock over the 90 calendar
days prior to the grant date and with such number of shares rounded down to the nearest whole share and (y) a restricted stock unit (“RSU”) award  covering
a number of shares of the Company’s common stock (the “Initial RSU Grant” and, together with the Initial Option Grant, the “Initial Grants”) with a value of
$100,000 determined by

1

 
 
 
 
 
 
 
 
 
 
 
dividing such dollar value by the average closing price of the Company’s common stock over the 90 calendar days prior to the grant date and rounding down
to the nearest whole share.  Each Initial Grant will vest in a series of three successive equal annual installments over the three-year period measured from
the date of grant, subject to the Non-Employee Director’s Continuous Service through each applicable vesting date.

(ii)

Annual Grant.  Without any further action of the Board, at the close of business on the date of each annual meeting of
the  Company’s  stockholders  (each,  an  “Annual  Meeting”),  each  person  who  is  then  a  Non-Employee  Director  will  automatically  be  granted:  (x)  a
Nonstatutory  Stock  Option  to  purchase  a  number  of  shares  of  the  Company’s  common  stock  (the  “Annual  Option  Grant”)  with  a  value  of  $70,000
determined  using  Black-Scholes’  valuation  methodology  based  on  the  average  closing  price  of  the  Company’s  common  stock  over  the  90  calendar  days
prior to the grant date and with such number of shares rounded down to the nearest whole share and (y) an RSU award covering a number of shares of
Company’s common stock (the “Annual RSU Grant” and, together with the Annual Option Grant, the “Annual Grants”) with a value of $70,000 determined
by dividing such dollar value by the average closing price of the Company’s common stock over the 90 calendar days prior to the grant date and rounding
down  to  the  nearest  whole  share.    Each  Annual  Grant  will  vest  upon  the  earlier  of  the  one  (1)  year  anniversary  of  the  grant  date  or  the  day  prior  to  the
Company’s next Annual Meeting occurring after the grant date, subject to the Non-Employee Director’s Continuous Service through the vesting date.

(b)

Change in Control.  Notwithstanding the foregoing vesting schedules, for each Non-Employee Director who remains in Continuous
Service  with  the  Company  until  immediately  prior  to  the  closing  of  a  Change  in  Control  (as  defined  in  the  Plan),  the  shares  subject  to  his  or  her  then-
outstanding equity awards that were granted pursuant to the Director Compensation Policy will become fully vested immediately prior to the closing of such
Change in Control.

(c)

Remaining Terms.  The remaining terms and conditions of each stock option or RSU award, including transferability, will be as set
forth in the Company’s standard Option or RSU award agreement, each in the form adopted from time to time by the Board, except that the post-termination
exercise  period  for  each  stock  option  granted  pursuant  to  the  Director  Compensation  Policy  shall  equal  the  lesser  of  (i)  36  months  from  the  date  of
termination of the Non-Employee Director’s Continuous Service for any reason other than removal with cause by a vote of the stockholders in accordance
with the Company’s bylaws and (ii) the remaining period of the applicable stock option’s ten-year term.

Expenses

The Company will reimburse Non-Employee Directors for ordinary, necessary and reasonable out-of-pocket travel expenses to cover in-person
attendance  at  and  participation  in  Board  and  committee  meetings;  provided,  that  the  Non-Employee  Director  timely  submits  to  the  Company  appropriate
documentation substantiating such expenses in accordance with the Company’s travel and expense policy, as in effect from time to time.

Non-Employee Director Compensation Limit

Notwithstanding anything herein to the contrary, the cash compensation and equity compensation that each Non-Employee Director is entitled to

receive under this Director Compensation Policy shall be subject to the limits set forth in Section 3(d) of the Plan.

AS ADOPTED PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002

I, John West, certify that:

2.

3.

4.

I have reviewed this Annual Report on Form 10-K of Personalis, Inc.;

Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the
