Item 1. Business.

Overview

PART I

Personalis’ strategy is to develop some of the world’s most advanced genetic tests for cancer. Today our tests are routinely used by many of the
largest oncology-focused pharmaceutical companies for analysis of patient samples from their clinical trials. More recently, we have also begun to work with
a growing number of leading cancer centers for clinical diagnostic use of our tests. We believe that adoption and publication by these key opinion leaders will
develop  an  advanced  standard  of  care  for  cancer  patients  and  eventual  broad  use  in  a  community  hospital  setting.  We  believe  that  our  tests  can
meaningfully  improve  outcomes  for  cancer  patients,  and  we  estimate  that  the  market  opportunity  for  our  tests  for  therapy  selection  and  monitoring  is
approximately $30 billion in the U.S.

In December 2021, we launched NeXT Personal, a next-generation, tumor-informed liquid biopsy assay designed to detect and quantify minimal
residual  disease  (“MRD”)  and  recurrence  in  patients  previously  diagnosed  with  cancer.  NeXT  Personal  is  designed  to  deliver  industry-leading  MRD
sensitivity down to the 1 part-per-million range, an approximately 10- to 100-fold improvement over other available technologies. NeXT Personal leverages
whole  genome  sequencing  of  a  patient’s  tumor  to  identify  up  to  1,800  specially-selected  somatic  variants  that  are  subsequently  used  to  create  a
personalized liquid biopsy panel for each patient. We believe this enables earlier detection across a broader variety of cancers and stages, including typically
challenging early stage, low mutational burden, and low-shedding cancers. NeXT Personal is also designed to simultaneously detect and quantify clinically
relevant mutations in circulating tumor-derived DNA (“ctDNA”) that may be used in the future to help guide therapy, when cancer is detected. These include
known  targetable  cancer  mutations,  drug  resistance  mutations,  and  new  variants  which  can  emerge  and  change  over  time,  especially  under  therapeutic
pressure. We consider this approach not just “tumor-informed”, but “comprehensively tumor-informed”. Our ultimate goal is not just to detect cancer, but to
provide  key  information  over  the  entire  course  of  the  patient’s  disease.  We  believe  this  can  be  better  for  patients,  more  informative  for  pharmaceutical
customers, and a larger business opportunity for us.

Our  strategy  is  to  work  with  world-class  medical  institutions.  To  that  end,  in  the  fourth  quarter  of  2021,  we  announced  a  collaboration  with  the
Mayo Clinic and in the first quarter of 2022, we announced one with the Moores Cancer Center at UC San Diego Health. In these collaborations, we provide
clinical  diagnostic  testing  and  research  sequencing  and  analysis  services  using  our  tissue-based  NeXT  Dx  test.  We  have  begun  to  test  clinical  patient
samples and are excited about the opportunity to work with these renowned cancer centers. If we achieve a favorable reimbursement decision for our NeXT
Dx test from the Molecular Diagnostic Services Program developed by Palmetto GBA (“MolDx”), we may also generate revenue in the future from some of
these collaborations. Given the advanced nature of our NeXT Dx test, we believe it is a good fit for high-end cancer centers, which have a dual mandate for
both clinical care and research. If these key opinion leaders have a positive experience using our tests, we are optimistic that this will also support broader
use of our platform by other clinicians in the future.

We  have  the  capacity  to  sequence  and  analyze  approximately  200  trillion  bases  of  DNA  per  week  in  our  facility.  We  believe  that  capacity  is
already larger than 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, NeXT Dx Test and NeXT Personal offerings. To date, we have sequenced more than 235,000 human samples, of
which more than 145,000 were whole human genomes.

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.  The  VA  MVP  is  the  largest  population
sequencing effort in the United States and we have delivered over 140,000 whole human genome sequence datasets to the VA MVP to date. The cumulative
value of task orders received from the VA MVP since inception is approximately $186 million, $178.1 million of which we had recognized as revenue as of
December 31, 2021. In September 2021, we received a task order from the VA MVP with a value of up to approximately $9.7 million, which was significantly
less than in prior years. At that time, we expected the reduced order amount was to be followed by a formal request for proposal (“RFP”) process and a
potential new contract to be awarded sometime late in the third quarter of 2022. However, recent discussions with our contacts at the VA MVP indicate that
there will be no RFP process in 2022. Accordingly, we do not expect to receive any new orders from the VA MVP this year nor to recognize any revenue from
the VA MVP beyond the current order and contract. Unless we receive an additional task order and/or enter into a new services agreement with the VA MVP
with a value comparable to that of our current contract and historical contracted orders, our revenue from the VA MVP is expected to decline significantly in
2022 and future periods. Given the strong growth we have already experienced in our oncology business in 2021, and the large market opportunity we see in
this space, we plan to focus primarily on cancer as we go forward.

In August 2021, we announced that we will relocate our corporate headquarters from Menlo Park to a new facility in Fremont, California and we
plan  to  beginning  moving  into  it  in  the  third  quarter  of  this  year.  We  signed  a  13.5-year  lease  for  the  100,000  square  foot  facility,  which  is  approximately
double the amount of space in our current Menlo Park location. The new facility is intended to allow for expansion of our laboratory for clinical testing to
support biopharma customers and clinical diagnostic testing. In addition, the new space is intended to support the expansion of research and development
efforts  to  bring  leading  edge  products  and  services  to  the  marketplace.  The  new  facility  will  also  provide  more  office  space  for  our  selling,  general  and
administrative workforce.

Our  current  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 pharmaceutical companies, biopharmaceutical companies, universities, non-profits, and government
entities.

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  two  major  classes  of  next-generation  therapeutics:  immunotherapies  and  targeted
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.

Genes  that  are  involved  in  the  mechanism  of  action  of  any  of  these  drugs  may  develop  mutations  reducing  or  eliminating  the  effectiveness  of
those drugs. These are called therapy resistance mutations. In many cases they only become evident after extended treatment of the patient with the drug.
When these are detected, it can be an important signal that the patient may benefit from a change to another drug. Thus, it is important not only to test for
mutations when a patient is first diagnosed, but periodically to check for the emergence of these potential resistance mutations. Unlike other tumor-informed
liquid  biopsy  tests  for  MRD,  our  NeXT  Personal  liquid  biopsy  test  was  designed  to  look  for  the  emergence  of  resistant  mutations  and  to  guide  decisions
about effective therapies for patients.

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.

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.

5

 
 
 
•

•

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.

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: precision oncology, clinical and companion diagnostics, pharma research, and population genomics.

NeXT Platform

NeXT  is  the  first  platform  to  enable  the  comprehensive  analysis  of  both  a  tumor  and  its  microenvironment  from  a  single  sample.  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  Personal  (liquid  biopsy  offering  for  personalized  tumor  tracking  for  patients),  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  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.

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

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.

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 anticipate that our exome-scale NeXT 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.

NeXT Personal is an advanced, tumor-informed liquid biopsy assay developed to deliver industry-leading MRD sensitivity in the range of 1-3 parts
per  million,  representing  a  10-  to  100-fold  improvement  over  other  available  methods.  NeXT  Personal  is  sample  sparing,  requiring  only  a  single  tube  of
blood, along with a tumor tissue sample. The use of ctDNA as a predictive biomarker for MRD following treatment for solid tumors is rapidly being integrated
into clinical trial design, translational research studies, and is on the verge of use in routine clinical care. While detection methods for ctDNA have rapidly
advanced, the limited sensitivity of these detection methods reduces its utility for diagnosing MRD across a variety of clinical applications. Standard-of-care
(“SOC”)  radiological-based  technologies,  including  CT,  PET  and  MRI  scans,  also  remain  limited  in  their  ability  to  detect  residual  disease  during  or  after
surgical or systemic therapy due to the minimum tumor volume required. Therefore reliable, sensitive detection and quantification of MRD remains a key
challenge,  particularly  in  early-stage  cancers,  where  timely  detection  of  small  micrometastatic  lesions  may  enable  treatment  that  prevents  progression  to
advanced metastatic, incurable disease. We believe that NeXT Personal addresses these challenges. In the biopharma setting, MRD is rapidly emerging as
a key biomarker in therapy development, whereby more sensitive detection and quantification of MRD may provide substantial benefits versus less sensitive
methods through the reduction of false negative detection of cancer.

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

7

 
 
 
 
 
 
 
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.

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.

Revenue in connection with our NeXT Platform products has grown rapidly in recent years, accounting for only a minimal proportion of revenue
prior  to  2020  but  now  accounting  for  over  two-thirds  of  revenue  for  the  year  ended  December  31,  2021,  excluding  revenue  from  the  VA  MVP  (discussed
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: exome sequencing, transcriptome sequencing, and targeted cancer panels.

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 revenue since inception, excluding revenue from the VA MVP (discussed below) and our growing revenue from our

NeXT Platform described above, were derived from ACE Platform products.

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. The VA MVP is the largest population
sequencing effort in the U.S. 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,

8

2020 and 2021. To date, we have been contracted to deliver over 140,000 genome sequence data sets to the VA MVP. 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 developed 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 revenue in recent years, 53% in 2021, 71% in 2020, and 67% in 2019. In
September 2021, we received a task order from the VA MVP with a value of up to approximately $9.7 million, which was significantly less than in prior years.
At that time, we expected the reduced order amount was to be followed by a formal RFP process and a potential new contract to be awarded sometime late
in the third quarter of 2022. However, recent discussions with our contacts at the VA MVP indicate that there will be no RFP process in 2022. Accordingly, we
do not expect to receive any new orders from the VA MVP this year nor to recognize any revenue from the VA MVP beyond the current order and contract.
Unless  we  receive  an  additional  task  order  and/or  enter  into  a  new  services  agreement  with  the  VA  MVP  with  a  value  comparable  to  that  of  our  current
contract and historical contracted orders, our revenue from the VA MVP is expected to decline significantly in 2022 and future periods.

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.

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 cancer and immune response. To achieve this mission, our strategy is to:

•

•

•

•

•

existing and new customers.

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

Invest  in  clinical,  regulatory,  and  reimbursement  infrastructure  for  NeXT  Dx  and  NeXT  Personal  (MRD  and  ongoing  patient
management).

Focus  our  early  diagnostic  commercialization  efforts  on  world-class  cancer  centers,  which  have  a  dual  mandate  for  patient  care
and advanced clinical research.

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 220,000 human samples, of which more than 145,000
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  1).  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 1. 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.

11

 
 
 
 
 
 
 
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  2021,  we  derived  92%  of  our  revenue  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 revenue comes from single
time point testing, we believe our revenue from multiple time-point testing will continue to grow. We also derive revenue from analysis of multiple customer
samples from the same patient and time point to assess genetic 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.

13

 
 
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 revenue.

In 2021, we had two customers account for 10% or more of our revenue: VA MVP at 53% and Natera, Inc. (“Natera”) at 10%. In 2020, VA MVP
accounted  for  71%  of  our  revenue  and  no  other  customer  accounted  for  10%  or  more.  In  2019,  we  had  two  customers  account  for  10%  or  more  of  our
revenue: VA MVP at 67% and Pfizer Inc. at 13%.

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,
Adela, Inc., ArcherDx, Inc., which was acquired by Invitae Corporation in October 2020, 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., Geneseeq Technology Inc., Genosity, Inc., which was acquired by Invitae Corporation in April 2021, GRAIL, Inc. (“GRAIL”), which
Illumina announced that it had acquired in August 2021, Guardant Health, Inc., Inivata Limited,  which  was  acquired  by  NeoGenomics,  Inc.  in  June  2021,
Invitae Corporation, Mount Sinai Genomics, Inc. which does business under the name Sema4, Natera, NanoString Technologies, Inc., NeoGenomics, Inc.,
Personal Genome Diagnostics, Inc., Predicine, 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 NeXT Platform, including applications and implementations for
enhancing  sequencing  coverage  of  certain  genomic  regions,  analyzing  cell-free  nucleic  acids,  and  creating  personalized  cancer  recurrence  detection
assays.  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.”

Our patent portfolio is comprised of patents and patent applications owned by the company. These patents and patent applications generally fall

into five broad categories:

•

•

•

•

•

our  ACE  assay  technology,  including  claims  directed  to  methods  for  enriching  sample  nucleic  acids  based  on  differences  in  GC-content,
molecular size, presence of genetic variations or rearrangements, epigenetic modifications, and species-origin (e.g., human and non-human);
hybrid  exome-genome  technologies,  including  claims  directed  to  methods  for  combining  exome  and  genome  sequencing  data  generated
from a sample to identify polymorphisms;
liquid biopsy methods, including claims directed to methods of analyzing sequenced cell-free and leukocyte-derived nucleic acids in a blood
sample to identify a tissue source, or recommend a drug treatment;
clinical interpretation methods, including claims directed to methods of ranking genes associated with a phenotype and inheritance pattern;
and
personalized genetic testing assays, including claims directed to methods for using sequencing data to create a personalized genetic test to
monitor cancer progression, or the recurrence of disease.

As of December 31, 2021, we own sixteen issued U.S. and foreign patents in China, the European Union, and the United Kingdom and several
pending U.S. and foreign patent applications. Issued U.S. patents in our portfolio of company-owned patents are expected to expire between 2033 and 2038,
excluding any 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 2041.

Government Regulations

Coverage and Reimbursement

Our ability, and the ability of our customers, to commercialize diagnostic tests based on our technology will depend in part on the extent to which
coverage  and  reimbursement  for  these  tests  will  be  available  from  third-party  payors.  Coverage  and  reimbursement  of  new  products  and  services  is
uncertain, and whether the companies that use our instruments to develop their own products or services will attain coverage and adequate reimbursement
is unknown. In the U.S., there is no uniform policy for determining coverage and reimbursement. Coverage can differ from payor to payor, and the process
for  determining  whether  a  payor  will  provide  coverage  may  be  separate  from  the  process  for  setting  the  reimbursement  rate.  In  addition,  the  U.S.
government, state legislatures and foreign governments have shown significant interest in implementing cost containment programs to limit the growth of
government-paid healthcare costs, including price controls and restrictions on reimbursement. Additionally, 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.

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

15

 
 
 
 
 
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 premarket approval application (“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 currently 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.  Despite  the  FDA’s  historic  enforcement  discretion  policy  with  respect  to  LDTs,  if  the  FDA  determines  that  our  tests  are  subject  to
enforcement  as  medical  devices,  we  could  be  subject  to  administrative  and  judicial  sanctions,  and  additional  regulatory  controls  and  submissions  for  our
tests, all of which could be burdensome. We and/or our collaborators may also voluntarily submit one or more of our tests for premarket notification, review,
clearance or approval by the FDA as medical devices, which may be as companion diagnostic medical devices.

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, or if we voluntarily submit one or more of our tests for premarket notification, review, clearance or approval by the FDA as medical devices, 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 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,  or  if  we  voluntarily  submit  one  or  more  of  our  tests  for
premarket  notification,  review,  clearance  or  approval  by  the  FDA  as  medical  devices,  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 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, or if we voluntarily submit one or more of our tests for premarket
notification, review, clearance or approval by the FDA as medical devices, one classification regulation that could be relevant to one or more of our tests is a
classification  for  genetic  health  risk  (“GHR”)  assessment  tests,  codified  at  21  C.F.R.  §  866.5950.  If  our  tests  are  considered  medical  devices  that  are  not
subject to enforcement discretion, or if we voluntarily submit one or more of our tests for premarket notification, review, clearance or approval by the FDA as
medical devices, 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.

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.

16

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;

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.

In addition, many of the products we use to perform our tests, including sequencers and various associated reagents supplied to us by Illumina,
are labeled as research use only (“RUO”) in the U.S. RUO products are exempt from FDA medical device requirements provided their manufacturers comply
with  specified  labeling  and  restrictions  on  distribution.  The  products  must  bear  the  statement:  “For  Research  Use  Only.  Not  for  Use  in  Diagnostic
Procedures.”  Manufacturers  of  RUO  products  cannot  make  any  claims  related  to  safety,  effectiveness  or  diagnostic  utility,  and  RUO  products  cannot  be
intended by the manufacturer for clinical diagnostic use. A product promoted for diagnostic use may be viewed by the FDA as adulterated and misbranded
under the FDC Act and is subject to FDA enforcement activities, including requiring the manufacturer to seek marketing authorization for the products. We
currently use Illumina and other RUO products for our clinical diagnostic tests. If the FDA were to require clearance, approval or authorization for the sale of
Illumina’s RUO products and if Illumina does not obtain such clearance, approval or authorization, we would have to find an alternative sequencing platform
for some or all of our clinical diagnostic tests.

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.

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.

The Eliminating Kickbacks in Recovery Act
The Eliminating Kickbacks in Recovery Act of 2018 (“EKRA”) prohibits payments for referrals to recovery homes, clinical treatment facilities, and
laboratories  and  is  similar  to  the  federal  Anti-Kickback  Statute  in  that  it  creates  criminal  penalties  for  knowing  or  willful  payment  or  offer,  or  solicitation  or
receipt,  of  any  remuneration,  whether  directly  or  indirectly,  overtly  or  covertly,  in  cash  or  in  kind,  in  exchange  for  the  referral  or  inducement  of  laboratory
testing unless a specific exception applies. Unlike the federal Anti-Kickback

17

 
 
 
 
 
 
 
 
 
 
 
Statute, EKRA’s reach extends beyond federal health care programs to include private insurance (i.e., it is an “all payer” statute). Additionally, most of the
safe harbors available under the federal Anti-Kickback Statute are not reiterated under EKRA, and certain EKRA safe harbors conflict with the safe harbors
available  under  the  federal  Anti-Kickback  Statute.  Therefore,  compliance  with  a  federal  Anti-Kickback  safe  harbor  does  not  guarantee  protection  under
EKRA. Because EKRA is a new law, there is very little additional guidance to indicate how and to what extent it will be interpreted, applied and enforced by
the  government.  Currently,  there  is  no  proposed  regulation  interpreting  or  implementing  EKRA,  nor  any  public  guidance  released  by  a  federal  agency
concerning EKRA.

Other Federal and State Healthcare Laws
In addition to the requirements discussed above, several other healthcare laws could have an effect on our business. For example, the Health
Insurance  Portability  and  Accountability  Act  of  1996  (“HIPAA”)  fraud  and  abuse  provisions  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 federal Physician Payments Sunshine Act 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),  other  healthcare  professionals  (such  as  physicians  assistants  and  nurse  practitioners)  and
teaching hospitals, and (ii) ownership and investment interests held by physicians and their immediate family members.

The “Anti-Markup Rule” and similar state laws prohibit, among other things, 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.

State client billing laws specify whether a person that did not perform the service is permitted to submit the claim for payment and if so, whether
the  non-performing  person  is  permitted  to  mark  up  the  cost  of  the  services  in  excess  of  the  price  the  purchasing  provider  paid  for  such  services.  For
example, California has an anti-markup statute which prohibits providers from charging for any laboratory test that it did not perform unless the provider (a)
notifies  the  patient,  client  or  customer  of  the  name,  address,  and  charges  of  the  laboratory  performing  the  test,  and  (b)  charges  no  more  than  what  the
provider was charged by the clinical laboratory which performed the test except for any other service actually rendered to the patient by the provider (for
example,  specimen  collection,  processing  and  handling)  (California  Business  and  Professions  Code  Section  655.5).  This  provision  applies,  with  certain
limited exceptions, to licensed persons such as physicians and clinical laboratories regulated under the Business and Professions Code. In addition, many
states also have “direct-bill” laws, which means that the services actually performed by an individual or entity must be billed by such individual or entity, thus
preventing ordering physicians from purchasing services from a laboratory and rebilling for the services they order. For example, California has a direct bill
rule  specific  to  anatomic  pathology  services  that  prohibits  any  provider  from  billing  for  anatomic  pathology  services  if  those  services  were  not  actually
rendered by that person or under his or her direct supervision with some exemptions (California Business and Professions Code Section 655.7).

In addition, we may be subject to 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.

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. 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 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

18

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.

There have been executive, judicial and Congressional challenges to 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 June 17, 2021 the U.S. Supreme Court dismissed a challenge on
procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus, the ACA will
remain  in  effect in its current form. Further, prior  to  the  U.S.  Supreme  Court  ruling,  on  January  28,  2021,  President  Biden  issued  an  executive  order  that
initiated a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace The executive order also instructed
certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining
Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to
health insurance coverage through Medicaid or the ACA. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. In
addition, Congress and the Biden administration are considering other health reform initiatives, such as the Build Back Better Plan. It is unclear how any
such challenges and the health reform measures of the Biden administration will impact the ACA.

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 2031, with the exception of a temporary suspension from May 1, 2020 through March 31,
2022, unless additional Congressional action is taken. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to
3% in the final fiscal year of this sequester. 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 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 (“APMs”), and the Merit-based Incentive Payment System (“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  revenue  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”),

19

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.  Reporting  of  payment  data  under  PAMA  for  clinical  diagnostic  laboratory  tests  has  been  delayed  on  numerous
occasions. Based on current law, between January 1, 2023 and March 31, 2023, applicable laboratories will be required to report on data collected during
January 1, 2019 and June 30, 2019. This data will be utilized to determine 2024 to 2026 CLFS rates. 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  current  tests  or  those  in  development.  In  addition,  CMS  updated  the  statutory  phase-in  provisions  such  that  the  rates  for  clinical
diagnostic laboratory tests in 2020 could not be reduced by more than 10% of the rates for 2019. Pursuant to the CARES Act, the statutory phase-in of the
payment reductions has been extended through 2024 with a 0% reduction cap for 2021-2022 and a 15% reduction cap for 2023 through 2025. 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.

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.
Further, it is possible that additional governmental action is taken to address the COVID-19 pandemic.

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. 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. We received contracted orders from the VA MVP in September 2017, 2018, 2019, 2020, and 2021. The current contract
does not include a renewal option. For us to provide additional services to the VA MVP after completion of the current contract, we would need to receive an
additional task order and/or enter into a new services agreement with the VA MVP, neither of which had occurred as of the date of filing this Annual Report.

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.

In September 2021, we received a task order from the VA MVP with a value of up to approximately $9.7 million, which was significantly less than
in prior years. At that time, we expected the reduced order amount was to be followed by a formal RFP process and a potential new contract to be awarded
sometime late in the third quarter of 2022. However, recent discussions with our contacts at the VA MVP indicate that there will be no RFP process in 2022.
Accordingly, we are not planning on receiving any new orders from the VA MVP this year or expecting to recognize any revenue from the VA MVP beyond
the current order and contract.

Agreements with Illumina

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
March 2022, or later if the VA MVP Agreement is extended.

The Subcontract Agreement extends through the last day of the VA MVP Agreement, currently March 2022 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

20

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

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.  We  offer  competitive  total  rewards  programs,  ongoing  training  and
development, and a commitment to the safety and health of our employees. We also practice a commitment to diversity by including broader outreach and
sourcing  for  candidates  for  new  roles  as  well  as  education  and  a  visible  commitment  to  diversity  and  inclusion  internally.  For  example,  we  established  a
Diversity Committee in 2020 with its mission to promote a sense of belonging for all our employees.

An  engaged  workforce  with  skills  specific  to  our  needs  is  critical  for  our  successful  growth  in  a  competitive  market  and  sector.  We  regularly
benchmark our compensation and benefits by geography, industry (life sciences), and by role to ensure we maintain our status as an employer of choice in
these areas. Our turnover rates over the last three years have been consistent with such benchmarks. Reports of our position relative to the benchmarks are
reported to management and the compensation committee of our board of directors on a periodic basis.

As of December 31, 2021, we had 326 employees, of which 325 were full-time employees. Of these full-time employees, 149 were in research
and development, 74 in laboratory operations, 55 in commercial operations and 47 in general and administrative functions. 311 of our full-time employees
are located in the United States, six are located in Europe and eight are located in China. As of December 31, 2021, more than 50% 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. The use of independent contractors is not a material part of our workforce strategy.

Environment

We  believe  we  are  in  compliance  with  the  regulations  established  by  the  state  of  California  Division  of  Occupational  Safety  and  Health
Requirements  and  California  Environmental  Protection  Agency  applicable  to  our  operations  in  Menlo  Park,  California.  This  includes,  but  is  not  limited  to,
having an Injury and Illness Prevention Program, a Hazard Communication Program, an Emergency Action Plan, a Chemical Hygiene Plan and an Exposure
Control  Plan,  which  are  captured  in  written  standard  operating  procedures  (“SOPs”).  We  provide  training  to  our  employees  on  these  SOPs.  We  are
committed to evaluate our compliance to such regulations on a recurring basis.

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 revenue
to achieve or sustain profitability.

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 revenue 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 the business or operations of our customers or other third parties with whom we conduct business.

We have substantial customer concentration, with a limited number of customers accounting for a substantial portion of our revenue and accounts
receivable; in particular, we currently derive a substantial portion of our revenue from our largest customers, the VA MVP and Natera.

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 should we need to do so.

We will need to invest in our infrastructure in advance of increased demand for our services; our failure to accurately forecast demand would have
a negative impact on our business and our 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  develop  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 future growth effectively, which could make it difficult to execute 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 revenue, 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.

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

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

•

•

•

•

•

•

•

•

•

•

•

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.

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.

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

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.

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.

As  of  December  31,  2021,  we  were  still  eligible  to  use  the  scaled  disclosures  of  a  smaller  reporting  company,  and  any  decision  on  our  part  to
comply only with certain reduced reporting and disclosure requirements applicable to smaller reporting companies could make our common stock
less attractive to investors.

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 revenue to achieve or sustain profitability.

We have incurred net losses since our inception. For the years ended December 31, 2021, 2020, and 2019 we had net losses of $65.2 million,
$41.3 million, and $25.1 million, respectively. As of December 31, 2021, we had an accumulated deficit of $247.1 million. To date, we have not generated
sufficient  revenue  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  revenue  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 revenue to achieve profitability and sustain our business.

We currently derive substantially all of our revenue from sales of our services. We began offering our services through our CLIA-certified, 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 revenue 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
revenue from sales of our services since 2013, our services may never gain significant acceptance in the marketplace and therefore may never generate
substantial revenue 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 and potential customers;

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

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

whether our customers and potential customers accept that our services are sufficiently sensitive and specific;

our ability to convince our customers and potential customers 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;

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 operations, our financial condition, 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. For example, the previous shelter-in-place order 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  return  in  similar  or  more  stringent  form,  they  may
continue to cause such effects on our operations. The COVID-19 pandemic has disrupted, and may continue to 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  and  vaccines.  We  use  such  consumables  in  our  operations,  and  we  have  faced,  and  may  face  in  the  future,  difficulties  in  acquiring  such
consumables if our suppliers prioritize orders related to COVID-19 or if other supply chain issues arise as a result of the COVID-19 pandemic. Several of our
customers, including the VA MVP, have been delayed in sending us samples 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 or samples to us in the future.

While authorities in many areas have lifted or relaxed pandemic-related restrictions, in some cases they have subsequently re-imposed various
restrictions after observing an increased rate of COVID-19 cases as the global COVID-19 pandemic continues to rapidly evolve and to present serious health
risks. There is no guarantee when or if all such restrictions and recommendations 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. The full extent of the impact of the COVID-19 pandemic on
our  business,  operations  and  plans  remains  uncertain  and  will  depend  on  future  developments  that  cannot  be  predicted  at  this  time.  Such  developments
include the continued spread of the Delta and Omicron variants in the U.S. and other countries and the potential emergence of other SARS-CoV-2 variants
that may prove especially contagious or virulent, the ultimate duration of the pandemic and the resulting impact on our business and other third parties with
whom we do business, and the effectiveness of actions taken globally to contain and treat the disease.

While vaccines for COVID-19 have been developed and administered, and the spread of COVID-19 may eventually be contained or mitigated, we
cannot predict the timing of the vaccine roll-out globally (including boosters to vaccinations), the percentage of the population that becomes vaccinated, or
the efficacy of such vaccines against Delta, Omicron or other variants, and we do not yet know how businesses, advertisers, or our partners will operate in a
post COVID-19 environment. In addition, there is no guarantee that a future outbreak of this or any other widespread epidemics will not occur, or that the
global economy will recover, either of which could seriously harm our business. The ultimate impact of the COVID-19 pandemic or a similar health epidemic
on our business, operations, or the global economy as a whole remains highly uncertain, but a continued and prolonged public health crisis 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 revenue 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 and
potential 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.  In  addition,  our  suppliers  or  competitors  may  announce  the  development  of  new  products,  services  or  features  that  result  in  our  customers  or
potential customers deciding to reduce, postpone or cancel orders from us while they wait to determine which products, services or features are or will be
perceived as technologically superior, more commercially successful or adopted as standards in the industry; such decisions by our customers or potential
customers may be influenced by their concerns regarding the potential obsolescence of data generated using our services and features if our services or
features are or will not be perceived as technologically superior, commercially successful or adopted as standards in the industry.

Some of our present or potential competitors, including Adaptive Biotechnologies Corporation, Adela, Inc., ArcherDx, Inc., which was acquired by
Invitae Corporation in October 2020, 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.,  Geneseeq  Technology
Inc.,  Genosity,  Inc.,  which  was  acquired  by  Invitae  Corporation  in  April  2021,  GRAIL,  which  Illumina  announced  that  it  had  acquired  in  August  2021,
Guardant Health, Inc., Inivata Limited, which was acquired by NeoGenomics, Inc. in June 2021, Invitae Corporation, Mount Sinai Genomics, Inc. which does
business under the name Sema4, Natera, NanoString Technologies, Inc., NeoGenomics, Inc., Personal Genome Diagnostics, Inc., Predicine, 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

25

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. Also, we have had, and may have in the future, customer or supply relationships with our present or potential competitors.
For example, we have an agreement with Natera to provide advanced tumor analysis for use in Natera’s MRD testing offerings. During 2021, revenue under
our  agreement  accounted  for  10%  of  our  total  revenue.  See  “—We  currently  derive  a  substantial  portion  of  our  revenue  from  DNA  sequencing  and  data
analysis services that we provide to Natera. If Natera’s demand for our DNA sequencing and data analysis services were to be substantially reduced, our
business,  financial  condition,  revenue  and  other  operating  results,  and  cash  flows  may  be  materially  harmed.”  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  August  2021,  Illumina  announced  it  completed  its  acquisition  of  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. Illumina is also one of our
significant  suppliers.  See  “—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.”  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,  or  if  we  cannot  maintain  successful  customer  or  supply  relationships  with  Natera,  Illumina  or
other present or potential 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 revenue 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  revenue  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.  In
addition,  we  have  limited  experience  developing  diagnostics,  have  never  developed  an  FDA-approved  companion  diagnostic,  and  may  be  unable  to
successfully compete against companies with more experience developing and commercializing companion diagnostics.

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 revenue
and accounts receivable; in particular, we currently derive a substantial portion of our revenue from our largest customers, the VA MVP
and Natera.

Like other genomic profiling companies that sell to the pharmaceutical industry, we have substantial customer concentration. We currently derive a
significant portion of our revenue from the VA MVP, which accounted for 53%, 71% and 67% of our revenue for the years ended December 31, 2021, 2020
and 2019, respectively. Our top five customers, including the VA MVP, accounted for 84%, 87% and 90% of our revenue for the years ended December 31,
2021, 2020 and 2019, respectively. There are inherent risks whenever a large percentage of revenue is concentrated with a limited number of customers.
While  we  have  attempted  to  grow  our  customer  base  and  diversify  our  revenue  concentration  beyond  the  VA  MVP  and  Natera,  we  may  not  be  able  to
successfully do so in the future. Our predictions  regarding  the  future  level  of  demand  for  our  services  that  will  be  generated  by  these  customers  may  be
wrong.  In  addition,  revenue  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,  including  Natera,  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

26

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 revenue 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 revenue, 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
revenue, cash position, and results of operations would be materially adversely impacted. Likewise, if Natera or any of our other significant customers were
to reduce or cease their use of our services, then our revenue, cash position, and results of operations may be materially adversely impacted. Further, if any
of our significant customers were to stop payment for our services, it would have a material adverse effect on our accounts receivable, increasing our credit
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 have derived a substantial portion of our current revenue from DNA sequencing and data analysis services that we provided 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 continues
to be substantially reduced, if the VA MVP conducts a competitive bid process for the next contract and we do not win, or if the VA MVP
does not award any such contract on a timely basis or at all, our business, financial condition, revenue and other operating results, and
cash flows will be materially harmed.

We  currently  derive  a  substantial  portion  of  our  revenue  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  optional  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, 2020, and 2021. The current contract does not include a renewal option. For
us to provide additional services to the VA MVP after completion of the current contract, we would need to receive an additional task order and/or enter into a
new services agreement with the VA MVP, neither of which had occurred as of the date of filing this annual report.

The VA MVP may initiate a competitive bidding process for its next DNA sequencing and data analysis services contract, if any. However, there
may not be any such potential bidding process or new contract awarded on a timely basis or at all, we may not win any such potential new contract in any
such potential bidding process, the value of any such potential new 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 significantly 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 had a value of up to approximately $31 million, whereas the VA MVP contracted order
received in September 2021 has a value of up to approximately $9.7 million, which represents a substantial decline. Unless we receive an additional task
order and/or enter into a new services agreement with the VA MVP with a value comparable to that of our current contract and historical contracted orders,
our revenue from the VA MVP will decline significantly in the future.

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 have changed or change in the future, 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 will 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 not to award a future contract on a timely basis or at all, or to terminate for convenience or failure to renew any contract, for whatever
reason), our business, financial condition, revenue and other operating results and cash flows will be materially harmed. The success of our business and
our future operating results are significantly dependent on the VA MVP’s continued demand and 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  2020
significantly  exceeded  the  value  of  the  VA  MVP  contracted  order  we  received  in  September  2020  because  we  continued  to  receive  after  such  date,  and
subsequently processed, samples under VA MVP contracted orders that remained unfulfilled as of September 2020 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  2020  contracted  order,  the  revenue  we  recognize  under  such  potential  new  contract  and  order  may  be  less  than  the  revenue  we
recognized during the 2020-2021 contract year. 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 2021 VA MVP contracted order
compared to the September 2020 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.

We currently derive a substantial portion of our revenue from DNA sequencing and data analysis services that we provide to Natera. If
Natera’s  demand  for  our  DNA  sequencing  and  data  analysis  services  were  to  be  substantially  reduced,  our  business,  financial
condition, revenue and other operating results, and cash flows may be materially harmed.

On February 17, 2021, we announced that we had entered into a partnership in the field of personalized oncology with Natera, pairing our NeXT
tumor profiling and diagnostic products with Natera’s personalized ctDNA platform Signatera™ for treatment monitoring and MRD assessment. Under this
non-exclusive agreement, Natera is responsible for validating the design of, and commercialization of, Signatera personalized ctDNA assays using matched
tumor  and  normal  exome  sequence  data  from  us.  The  agreement  covers  MRD  testing  for  both  clinical  use  and  research  use.  Since  that  time,  Natera’s
sample  volumes  have  increased  such  that  we  currently  derive  a  significant  portion  of  our  revenue  from  sales  of  our  DNA  sequencing  and  data  analysis
services  to  Natera  under  our  agreement.  For  example,  during  2021,  revenue  under  our  agreement  accounted  for  10%  of  our  total  revenue.  While  our
agreement  with  Natera  is  a  long-term  contractual  arrangement,  Natera  is  not  required  to  purchase  a  minimum  number  of  analyses  from  us  under  the
agreement, and we have only limited visibility to Natera’s forecasted sample volumes for future periods. We are aware that Natera has at least one third
party supplier of DNA sequencing and analysis services, such that Natera has elected, and may continue to elect in the future, to send a portion (or all) of its
samples to its other supplier(s) instead of us, which it is not contractually prohibited from doing, given the non-exclusive nature of our agreement. Natera
may also bring a portion (or all) of such services in-house in the future, which may result in them purchasing fewer (or no) such services from us, or none
from us at all. Our agreement with Natera requires us to achieve certain quality and turnaround time metrics for Natera samples. Recently, the volumes of
samples sent to us by Natera have fluctuated significantly and may continue to do so in the future, which could cause us to experience difficulty in achieving
such  metrics  from  time  to  time,  or  to  meet  our  other  obligations  under  our  agreement.  If  we  consistently  fail  to  achieve  such  metrics,  or  any  of  our  other
obligations under our agreement with Natera, Natera may elect to send a portion (or all) of its samples to its other supplier(s) and/or bring such services in-
house.

Additionally,  Natera  may  allege  that  such  failures  to  achieve  the  required  metrics  are  a  breach  of  our  agreement  and  seek  to  terminate  our
agreement and/or pursue any remedies available to it under the agreement, at law or in equity. Relatedly, we have incurred expenses in connection with our
scale-up  activities  under  our  agreement  with  Natera,  and  we  may  incur  additional  expenses  to  increase  our  laboratory’s  capacity  to  process  increased
sample volumes from Natera, in addition to those from our other customers, in the future. Our activities under our agreement with Natera have had, and may
continue to have, an impact on our business, including diversion of our resources and the attention of our management, including with respect to our internal
research  and  development  objectives  and  projects  for  our  other  customers,  collaborators  and/or  partners.  If  we  are  unable  to  successfully  increase  our
laboratory’s  capacity  and  manage  any  such  competing  objectives  and/or  projects  for  other  customers,  we  may  be  unable  to  meet  the  quality  and  timing
requirements of our agreement with Natera or our other customers, collaborators and/or partners. We may also be unable to successfully research, develop,
launch  and/or  commercialize  our  services  or  service  capabilities.  Furthermore,  we  recently  announced  the  launch  of  NeXT  Personal,  a  next-generation,
tumor-informed liquid biopsy assay designed to detect and quantify MRD and recurrence in patients previously diagnosed with cancer. If NeXT Personal or
any of our other services is seen as competing with Signatera or any of Natera’s other services, we will still be required to fulfill our obligations to Natera
under our agreement, although Natera may elect to send a portion (or all) of its samples to its other supplier(s) and/or bring such services in-house. If the
volume of samples received under our agreement with Natera were to be significantly reduced or eliminated, or if our agreement with Natera were to be
terminated,  for  these  or  other  reasons,  or  if  we  are  unable  to  successfully  research,  develop,  launch  and/or  commercialize  our  services  or  service
capabilities, including NeXT Personal, our business, financial condition, revenue and other operating results, and cash flows may be materially harmed.

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 and Natera 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.

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 revenue 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
revenue.

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 other materials used in our routine laboratory operations, and as
the sole provider of maintenance and repair services for these sequencers. Our Subcontract Agreement with Illumina is set to expire in March 2022, and our
various  pricing  agreements  with  Illumina  are  set  to  expire  on  various  dates  up  to  December  2022.  In  August  2021,  Illumina  completed  its  acquisition  of
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 acquisition of GRAIL, could negatively impact our supply chain and laboratory operations and our ability to conduct our
business  and  generate  revenue.  Additionally,  the  COVID-19  pandemic  has  disrupted,  and  may  continue  to  disrupt,  Illumina’s  ability  to  perform  under  our
Subcontract Agreement and fulfill our purchase orders for reagents or other materials in a timely manner and the pandemic has also disrupted, and may
continue  to  disrupt,  the  ability  of  our  other  suppliers  to  fulfill  our  purchase  orders  in  a  timely  manner  or  at  all.  Our  suppliers  could  cease  supplying  these
materials  and  equipment  at  any  time,  or  fail  to  provide  us  with  sufficient  quantities  of  materials  or  equipment  that  meet  our  specifications.  Our  laboratory
operations have been and in the future could be interrupted if we encounter delays or difficulties in securing sequencers or other equipment or materials, 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.  Likewise,  we  believe  that  there  are  a  limited  number  of
manufacturers and suppliers for other reagents and materials necessary for our laboratory operations, such as the sample preparation reagents required for
our  ACE  technology,  which  enables  our  NeXT  Platform  to  provide  more  comprehensive  sequencing  coverage,  as  well  as  those  required  to  create
personalized  liquid  biopsy  panels  for  each  patient  as  part  of  our  NeXT  Personal  assay.  Although  we  have  evaluated  and  may  continue  in  the  future  to
evaluate equipment and materials from other suppliers, 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.  Additionally,  an  existing
supplier of ours may allege that such activities constitute a breach of its agreement with us and may cease supplying us with sufficient quantities of materials
or  equipment  that  meet  our  specifications,  in  a  timely  manner  or  at  all.  Moreover,  an  existing  supplier  or  third  party  may  allege  that  such  activities,
replacement  equipment  or  materials  infringe,  misappropriate  or  otherwise  violate  its  intellectual  property,  and  may  bring  infringement  or  other  intellectual
property-related claims against us. See “—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.” 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 other 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.

We will need to invest in our infrastructure in advance of increased demand for our services; 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  revenue  does  not  meet  our  expectations  we  may  not  be  able  to  promptly  adjust  or  reduce  our  spending  to  levels
commensurate  with  our  revenue.  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.

29

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  revenue  from  our  genomic  analysis  conducted  in  our  laboratories.  Currently,  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  and  planned  future  facilities  in  Fremont,  California.  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 planned opening of our new headquarters and laboratory facilities in Fremont, California could divert management’s attention and
disrupt our ongoing business.

We plan to relocate our corporate headquarters to an existing building located in Fremont, California that was leased in August 2021. We also
plan  to  build  and  operate  new  laboratory  facilities  in  the  building.  These  efforts  will  involve  significant  tenant  improvements,  construction  and  regulatory
compliance activities to be undertaken, including state licensure and CLIA certification for such laboratory facilities. Such efforts may distract management
from  current  operations,  disrupt  planned  research,  development  or  regulatory  compliance  activities,  and  result  in  greater  than  expected  liabilities  and
expenses, any of which could result in a material adverse effect on our business prospects, financial condition, or results of operations.

Our success depends on our ability to provide reliable and timely, 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. In addition, our customers require timely turnaround of high-quality genomic data and analyses, and if we were not able to
meet our customers’ specific requirements, it could also have a significant adverse effect 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, lack of efficacy, side effects or adverse events in patients who use our tests, or who rely on our tests to determine therapies to develop,
select  or  monitor,  including  treatment-related  death,  and  could  lead  to  termination  of  our  services  or  result  in  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.

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.

30

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 IVDs. 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, among 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
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.

Our ability, and the ability of our customers, to commercialize diagnostic tests based on our technology will depend in part on the extent to which
coverage  and  reimbursement  for  these  tests  will  be  available  from  third-party  payors.  Coverage  and  reimbursement  of  new  products  and  services  is
uncertain, and whether the companies that use our instruments to develop their own products or services will attain coverage and adequate reimbursement
is unknown. In the U.S., there is no uniform policy for determining coverage and reimbursement. Coverage can differ from payor to payor, and the process
for  determining  whether  a  payor  will  provide  coverage  may  be  separate  from  the  process  for  setting  the  reimbursement  rate.  In  addition,  the  U.S.
government, state legislatures and foreign governments have shown significant interest in implementing cost containment programs to limit the growth of
government-paid healthcare costs, including price controls and restrictions on reimbursement.

31

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 Medical 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 (“CLS”), 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. For example, California has a shortage of qualified CLS, who must be licensed by the California Department of Public Health to perform clinical testing
in laboratories located in California such as our CLIA-certified and CAP-accredited laboratory. We face intense competition for, and we have experienced
and may in the future experience difficulty attracting and retaining, sufficient numbers of licensed and qualified CLS to support the needs of our business and
our laboratory capacity expansion efforts. 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,  including  licensed  and  qualified  CLS,  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 (such as
our planned future facilities in Fremont, California), 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.

32

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  (for  example,  our  collaborations  with  the  Mayo  Clinic,  MapKure,  LLC  (“MapKure”),  which  is  jointly-owned  by  BeiGene,  Ltd.  and  SpringWorks
Therapeutics,  Inc.,  and  Moores  Cancer  Center  at  UC  San  Diego  Health)  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;

collaborators with marketing, manufacturing, and distribution rights to one or more services or products may not commit sufficient resources
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;

a large percentage of our revenue may be concentrated with the collaborators if the collaborations are successful and we may experience
further losses if they are or later become unsuccessful;

collaborators  may  not  properly  maintain  or  defend  our  intellectual  property  rights  or  may  use  our  intellectual  property  or  proprietary
information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary
information or expose us to potential liability;

disputes may arise between us and a collaborator that causes the delay or termination of the research, development, or commercialization of
our current or future services or products or that results in costly litigation or arbitration that diverts management attention and resources;

collaborations  may  be  terminated,  and,  if  terminated,  may  result  in  a  need  for  additional  capital  to  pursue  further  development  or
commercialization of the applicable current or future services or products;

collaborators may own or co-own intellectual property covering our services or products that results from our collaborating with them, and in
such cases, we would not have the exclusive right to develop or commercialize such intellectual property;

collaborators’ activities or use of our services or deliverables may create additional regulatory obligations and could lead to side effects or
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, including those that restrict
foreign investment in the development and application of gene diagnosis and treatment technologies (which we believe prevent us from directly offering our
NeXT  Dx  test,  or  other  diagnostic  tests  based  on  our  NeXT  Platform,  to  patients  in  China);  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  or  new  restrictions  imposed  by  the  U.S.  government  on  the  export  of  necessary  goods  or
technologies to our Shanghai subsidiary. 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. For example, we understand
that the initial application by one of our pharmaceutical customers for such a project approval was previously rejected by such agency in China for reasons
relating to data retention by our customer and sharing of rights to research results with our customer’s collaborator in China. Although it is our understanding
that the agency’s decision was not based on the use of our NeXT Platform in the project, and that the agency subsequently approved applications by our
customer  for  this  project  and  another  project  also  involving  the  use  of  our  NeXT  Platform,  we  are  supporting  and  expect  in  the  future  to  support  the
preparation of multiple such applications, and there is no guarantee that any such additional applications will be approved by such agency in the future. The
Chinese  government  separately  has  various  regulations  relating  to  the  collection,  use,  storage,  disclosure,  and  security  of  data,  among  other  things,
including the new Personal Information Protection Law (“PIPL”) passed by the Standing Committee of China’s National People’s Congress on August 20,
2021, which took effect on November 1, 2021 and contains provisions similar to those of the General Data Protection Regulation (EU) 2016/679 (“GDPR”)
adopted by the EU, including extraterritorial reach, restrictions on data transfer, compliance obligations and sanctions for non-compliance. We cannot assure
you  that  we  will  be  able  to  comply  with  all  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. For example, the consequences for failing to comply with
the  PIPL  could  potentially  include  monetary  penalties,  business  suspension  and  revocation  of  business  licenses.  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 revenue
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
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. We and/or our collaborators may also voluntarily submit one or more of our tests for premarket
notification, review, clearance or approval by the FDA as medical devices. For example, under our collaboration with MapKure, we expect to develop new,
advanced biomarkers selected by MapKure for regulatory submission and approval as a companion diagnostic, in which case we would also be subject to
potentially burdensome additional regulatory controls and submissions for one or more of our tests. 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

35

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 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, or if we voluntarily submit one or more of our tests for premarket notification, review, clearance or approval by the FDA as medical devices, 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 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,  or  if  we  voluntarily  submit  one  or  more  of  our  tests  for
premarket  notification,  review,  clearance  or  approval  by  the  FDA  as  medical  devices,  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 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.

36

If our tests are considered medical devices not subject to enforcement discretion, or if we voluntarily submit one or more of our tests for premarket
notification, review, clearance or approval by the FDA as medical devices, one classification regulation that could be relevant to one or more of our tests is a
classification for GHR assessment tests, codified at 21 C.F.R. § 866.5950. If our tests are considered medical devices that are not subject to enforcement
discretion, or if we voluntarily submit one or more of our tests for premarket notification, review, clearance or approval by the FDA as medical devices, 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 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  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 revenue 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;

37

 
 
 
 
 
•

•

•

•

•

•

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;

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.

In addition, many of the products we use to perform our tests, including sequencers and various associated reagents supplied to us by Illumina,
are  labeled  as  RUO  in  the  U.S.  RUO  products  are  exempt  from  FDA  medical  device  requirements  provided  their  manufacturers  comply  with  specified
labeling  and  restrictions  on  distribution.  The  products  must  bear  the  statement:  “For  Research  Use  Only.  Not  for  Use  in  Diagnostic  Procedures.”
Manufacturers of RUO products cannot make any claims related to safety, effectiveness or diagnostic utility, and RUO products cannot be intended by the
manufacturer for clinical diagnostic use. A product promoted for diagnostic use may be viewed by the FDA as adulterated and misbranded under the FDC
Act  and  is  subject  to  FDA  enforcement  activities,  including  requiring  the  manufacturer  to  seek  marketing  authorization  for  the  products.  We  currently  use
Illumina and other RUO products for our clinical diagnostic tests. If the FDA were to require clearance, approval or authorization for the sale of Illumina’s
RUO products and if Illumina does not obtain such clearance, approval or authorization, we would have to find an alternative sequencing platform for some
or all of our clinical diagnostic tests. We currently have not validated an alternative sequencing platform on which our tests could be run in a commercially
viable  manner.  If  we  were  not  successful  in  selecting,  acquiring  on  commercially  reasonable  terms  and  implementing  an  alternative  platform  on  a  timely
basis,  our  business,  financial  condition  and  results  of  operations  would  be  adversely  affected.  Similarly,  a  finding  that  any  of  our  other  suppliers  failed  to
comply with applicable requirements could result in interruptions in our ability to supply our services to the market and adversely affect our operations.

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 revenue 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, if any of our products otherwise fail to comply with FDA regulatory requirements as enforced, or if we
voluntarily submit one or more of our tests for premarket notification, review, clearance or approval by the FDA as medical devices, 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 revenue, 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 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, receive, generate, use, transfer, disclose, make accessible, protect, secure, dispose
of, transmit, share and store proprietary, confidential, and sensitive information, including 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. Our ability to monitor these third parties’ security practices is limited, and
these third parties may not have adequate security measures in place.

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, which may compromise
our system infrastructure, or that of our third-party partners, or lead to data leakage. Cyberattacks, malicious internet-based activity, and online and offline
fraud are prevalent and continue to increase. These threats are becoming increasingly difficult to detect. We and the third parties upon which we rely may be
subject to a variety of evolving threats, including but not limited to social-engineering attacks (including through phishing attacks), malicious code (such as
viruses and worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks (such as credential stuffing), personnel
misconduct or error, ransomware attacks, supply-chain attacks, software

39

bugs, server malfunctions, software or hardware failures, loss of data or other information technology assets, adware, and other similar threats. Ransomware
attacks, including by organized criminal threat actors, nation-states, and nation-state-supported actors, are becoming increasingly prevalent and severe and
can lead to significant interruptions in our operations, loss of data and income, reputational harm, and diversion of funds. Extortion payments may alleviate
the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations
prohibiting  such  payments.  Similarly,  supply-chain  attacks  have  increased  in  frequency  and  severity,  and  we  cannot  guarantee  that  third  parties  and
infrastructure in our supply chain or our third-party partners’ supply chains have not been compromised or that they do not contain exploitable defects or
bugs that could result in a breach of or disruption to our information technology systems or the third-party information technology systems that support us
and our services.

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, threat actors, viruses, sophisticated nation states, and nation-state-supported actors, 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 and technologies 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.
Additionally, we cannot be sure that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay
future  claims.  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.

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  of  the  previously  identified  or  similar  threats  could  cause  a  security  incident  or  other  interruption,  which  could  result  in
unauthorized,  unlawful,  or  accidental  acquisition,  modification,  destruction,  loss,  alteration,  encryption,  disclosure  of,  or  access  to  our  proprietary,
confidential, or sensitive information. A security incident or other interruption could disrupt our ability (and that of third parties upon whom we rely) to provide
our  platform,  products,  and  services.  We  may  expend  significant  resources  or  modify  our  business  activities  (including  our  clinical  trial  activities)  to  try  to
protect against security incidents. Additionally, certain privacy, data protection, or data security obligations may require us to implement and maintain certain
measures to protect our information technology systems and sensitive information.

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.  We  may  be  unable  in  the  future  to  detect  vulnerabilities  in  our
information technology systems because such threats and techniques change frequently, are often sophisticated in nature, and may not be detected until
after  a  security  incident  has  occurred.  For  example,  if  such  an  event  were  to  occur  and  cause  interruptions  in  our  operations,  or  those  of  our  third-party
vendors and other 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.

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 HIPAA and HITECH, and penalties. Applicable privacy, data protection, or data security obligations may require us
to notify relevant stakeholders of security incidents. Such disclosures are costly, and the disclosure or the failure to comply with such requirements could
lead to adverse consequences. Notice of certain security breaches must be made to affected individuals, the Secretary of 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.

40

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 CCPA also allows for statutory fines for noncompliance
of up to $7,500 per violation. 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 revenue 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
policies, industry standards, and 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.

For example, the EU adopted the 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.

In addition, in January 2021, following its exit from the EU, the UK implemented its own version of the GDPR (the “UK GDPR”), which currently
imposes  substantively  similar  obligations  as  the  GDPR  and  provides  for  fines  of  up  £17.5  million  or  4%  of  global  turnover,  whichever  is  greater,  for  non-
compliance. In addition, an actual or asserted violation of the GDPR or UK GDPR could result in regulatory investigations, reputational damage, orders to
cease  or  change  our  processing  of  our  data,  enforcement  notices  and/or  assessment  notices  (for  a  compulsory  audit).  We  also  may  face  civil  claims,
including representative actions and other class action-type litigation (where individuals have suffered harm), potentially resulting in our paying significant
compensation or damages, or incurring other significant liabilities, as well as associated costs, diversion of internal resources, and reputational harm.

The relationship between the UK and the EU in relation to certain aspects of privacy, data protection, and data security laws is subject to some
uncertainty. For example, on June 28, 2021, the European Commission announced a decision of “adequacy” concluding that the UK ensures an equivalent
level of data protection to the GDPR, which provides some relief regarding the legality of continued personal information flows from the European Economic
Area (“EEA”) to the UK. This adequacy determination will automatically expire in June 2025 unless the European Commission renews or extends it and may
be modified or revoked in the interim. We cannot predict how the UK GDPR and other UK data protection laws or regulations may develop, including as
compared to the GDPR, nor can we predict the effects of divergent laws and related guidance. Changes with respect to any of these matters may lead to
additional costs and increase our overall risk exposure, particularly if the GDPR and UK GDPR develop in conflicting or otherwise divergent ways.

41

Further, European and UK privacy, data protection, and data security laws, including the GDPR and the UK GDPR, generally restrict the transfer
of personal information from the UK, 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 UK 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. The European Commission recently released a set of Standard
Contractual Clauses (“SCCs”) that is designed to be a valid mechanism by which entities can transfer personal data out of the EEA to jurisdictions that the
European  Commission  has  not  found  to  provide  an  adequate  level  of  protection. Currently,  the  SCCs  are  a  valid  mechanism  to  transfer  personal  data
outside  of  the  EEA.  The  SCCs,  however,  require  parties  that  rely  upon  that  legal mechanism  to  comply  with  additional  obligations,  such  as  conducting
transfer impact assessments to determine whether additional security  measures  are  necessary  to  protect  the  transferred  personal  information.  Moreover,
due to potential legal challenges, there is uncertainty regarding whether the SCCs will remain a valid mechanism for transfers of personal information out of
the EEA. Similarly, the UK’s Information Commissioner’s Office has released a draft international data transfer agreement (“IDTA”) governing data transfers
much like the SCCs. 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 or UK 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 Standard Contractual Clauses and the
IDTA.

Similar laws have been proposed in other foreign jurisdictions in which we do, or expect to do, business. For example, the PIPL was adopted in
China  on  August  20,  2021,  and  it  went  into  effect  on  November  1,  2021.  The  PIPL  shares  certain  similarities  with  the  GDPR,  including  extraterritorial
application, requirements for data minimization, data localization, and purpose limitation, and obligations to provide certain notices to and honor data subject
rights from individuals located in the PRC. The PIPL allows for fines of up to 50 million yuan or 5% of a covered company’s revenue in the prior year. The
PIPL, and other new and evolving laws and regulations relating to privacy, data protection, and data security in China and other relevant foreign jurisdictions,
increase  our  risk  exposure,  and  may  require  us  to  modify  our  operations,  may  limit  our  ability  to  collect,  retain,  store,  use,  share,  disclose,  transfer,
disseminate,  and  otherwise  process  personal  information,  may  require  additional  investment  of  resources  in  compliance  programs,  and  could  result  in
increased compliance costs or changes in our ongoing or planned business practices, policies or strategies.

In the United States, federal, state, and local governments have enacted numerous privacy, data protection, and data security laws, including data
breach  notification  laws,  personal  data  privacy  laws,  and  consumer  protection  laws.  For  example,  HIPAA,  as  amended  by  HITECH,  imposes  specific
requirements  relating  to  the  privacy,  security,  and  transmission  of  individually  identifiable  health  information.  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. It allows for statutory fines for noncompliance (up to $7,500 per violation). Although the
CCPA exempts some data processed in the context of clinical trials, the CCPA may increase our compliance costs and potential liability with respect to other
personal information we maintain about California residents. 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 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.

The  enactment  of  the  CCPA  has  led  a  wave  of  similar  legislative  developments  in  other  states  in  the  U.S.,  which  creates  the  potential  for  a
patchwork of overlapping but different state laws and could mark the beginning of a trend toward more stringent privacy legislation in the U.S., which could
increase our potential liability and adversely affect our business, financial condition and results of operations. For example, in March 2021, Virginia enacted
the Virginia Consumer Data Protection Act, a comprehensive privacy, data protection, and data security statute that becomes effective on January 1, 2023
(at the same time as the CPRA) and shares similarities with the CCPA, the CPRA, and legislation proposed in other states. In June 2021, Colorado enacted
a similar law, the Colorado Privacy Act, which becomes effective on July 1, 2023. Many other states are considering proposed comprehensive data privacy
legislation and all 50 states have passed some form of legislation relating to privacy or cybersecurity (for example, all 50 states have enacted laws requiring
disclosure of certain personal information breaches). Additionally, several states and localities have enacted statutes banning or restricting the collection of
biometric information. At the federal level, the United States Congress is considering various proposals for comprehensive federal privacy, data protection,
and data security legislation and, while no such law currently exists, we are subject to applicable existing federal laws and regulations, such as the rules and
regulations promulgated under the authority of the Federal Trade Commission, which regulates unfair or deceptive acts or practices, including with respect to
privacy,  data  protection,  and  data  security.  These  state  statutes,  and  other  similar  state  or  federal  laws,  may  require  us  to  modify  our  data  processing
practices  and  policies  and  incur  substantial  compliance-related  costs  and  expenses.  Additionally,  many  laws  and  regulations  relating  to  privacy  and  the
collection, storing, sharing, use, disclosure, and other processing or protection of certain types of data are subject to varying degrees of enforcement and
new  and  changing  interpretations  by  courts.  These  laws  and  other  changes  in  laws  or  regulations  relating  to  privacy,  data  protection,  and  data  security,
particularly  any  new  or  modified  laws  or  regulations,  or  changes  to  the  interpretation  or  enforcement  of  such  laws  or  regulations,  that  require  enhanced
protection  of  certain  types  of  data  or  new  obligations  with  regard  to  data  retention,  transfer,  or  disclosure,  could  greatly  increase  our  operating  costs,  or
require changes to our operations.

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 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 are or 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, which, 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;

state client billing laws, which specify whether a person that did not perform the service is permitted to submit the claim for payment and if so,
whether the non-performing person is permitted to mark up the cost of the services in excess of the price the purchasing provider paid for
such services. For example, California has an anti-markup statute which prohibits providers from charging for any laboratory test that it did
not perform unless the provider (a) notifies the patient, client or customer of the name, address, and charges of the laboratory performing the
test, and (b) charges no more than what the

43

 
 
 
 
provider was charged by the clinical laboratory which performed the test except for any other service actually rendered to the patient by the
provider  (for  example,  specimen  collection,  processing  and  handling)  (California  Business  and  Professions  Code  Section  655.5).  This
provision  applies,  with  certain  limited  exceptions,  to  licensed  persons  such  as  physicians  and  clinical  laboratories  regulated  under  the
Business and Professions Code. In addition, many states also have “direct-bill” laws, which means that the services actually performed by an
individual or entity must be billed by such individual or entity, thus preventing ordering physicians from purchasing services from a laboratory
and rebilling for the services they order. For example, California has a direct bill rule specific to anatomic pathology services that prohibits any
provider from billing for anatomic pathology services if those services were not actually rendered by that person or under his or her direct
supervision with some exemptions (California Business and Professions Code Section 655.7);

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

the 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 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),  other  healthcare  professionals  (such  as  physicians  assistants  and  nurse
practitioners) and teaching hospitals, and (ii) ownership and investment interests held by physicians and their immediate family members;

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;

HIPAA, as amended by HITECH, and their respective implementing regulations, which impose obligations on certain healthcare providers,
health plans, and healthcare clearinghouses, known as covered entities, as well as individuals and entities that create, receive, maintain or
transmit individually identifiable health information for or on behalf of a covered entity, known as business associates, as well as their covered
subcontractors, with respect to safeguarding the privacy, security and transmission of individually identifiable health information. HITECH also
created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates,
and  gave  state  attorneys  general  new  authority  to  file  civil  actions  for  damages  or  injunctions  in  U.S.  federal  courts  to  enforce  the  federal
HIPAA laws and seek attorneys' fees and costs associated with pursuing federal civil actions;

EKRA,  which  prohibits  payments  for  referrals  to  recovery  homes,  clinical  treatment  facilities,  and  laboratories  and  is  similar  to  the  federal
Anti-Kickback Statute in that it creates criminal penalties for knowing or willful payment or offer, or solicitation or receipt, of any remuneration,
whether directly or indirectly, overtly or covertly, in cash or in kind, in exchange for the referral or inducement of laboratory testing unless a
specific exception applies. Unlike the federal Anti-Kickback Statute, EKRA’s reach extends beyond federal health care programs to include
private insurance (i.e., it is an “all payer” statute). Additionally, most of the safe harbors available under the federal Anti-Kickback Statute are
not reiterated under EKRA, and certain EKRA safe harbors conflict with the safe harbors available under the federal Anti-Kickback Statute.
Therefore, compliance with a federal Anti-Kickback safe harbor does not guarantee protection under EKRA. Because EKRA is a new law,
there  is  very  little  additional  guidance  to  indicate  how  and  to  what  extent  it  will  be  interpreted,  applied  and  enforced  by  the  government.
Currently,  there  is  no  proposed  regulation  interpreting  or  implementing  EKRA,  nor  any  public  guidance  released  by  a  federal  agency
concerning EKRA;

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  as  discussed  above;  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 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, including services we provide under our agreement with Natera, 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 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 revenue, 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.

45

 
 
 
 
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  June  17,  2021  the  U.S.  Supreme  Court  dismissed  a  challenge  on  procedural  grounds  that  argued  the  ACA  is
unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus, the ACA will remain in effect in its current form. Further,
prior  to  the  U.S.  Supreme  Court  ruling,  on  January  28,  2021,  President  Biden  issued  an  executive  order  that  initiated  a  special  enrollment  period  for
purposes of obtaining health insurance coverage through the ACA marketplace The executive order also instructed certain governmental agencies to review
and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and
waiver  programs  that  include  work  requirements,  and  policies  that  create  unnecessary  barriers  to  obtaining  access  to  health  insurance  coverage  through
Medicaid or the ACA. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. Efforts to repeal, substantially modify or
invalidate some or all of the provisions of the ACA create considerable uncertainties for all businesses involved in healthcare, including our own. It is unclear
how such 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  2031,  with  the  exception  of  a  temporary  suspension  from  May  1,  2020
through March 31, 2022, unless additional Congressional action is taken. Under current legislation, the actual reduction in Medicate payments will vary from
1% in 2022 to up to 3% in the final fiscal year of this sequester. 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.  MACRA  repealed  the  formula  by  which  Medicare  made  annual  payment  adjustments  to
physicians and replaced the former 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 APMs and 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  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 revenue 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. Reporting of payment data under PAMA for clinical diagnostic laboratory tests has been
delayed on numerous occasions. Based on current law, between January 1, 2023 and March 31, 2023, applicable laboratories will be required to report on
data  collected  during  January  1,  2019  and  June  30,  2019.  This  data  will  be  utilized  to  determine  2024  to  2026  CLFS  rates.  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 current tests or those in development. In addition, CMS updated the statutory phase-in provisions such that
the rates for clinical diagnostic laboratory tests in 2020 could not be reduced by more than 10% of the rates for 2019.

Pursuant to the CARES Act, the statutory phase-in of the payment reductions has been extended through 2024 with a 0% reduction cap for 2021-
2022  and  a  15%  reduction  cap  for  2023  through  2025.  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.

46

 
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. President Biden is considering further repeals and/or replacement of the Tax Cuts and Jobs Act which
may affect us. On June 29, 2020, California Assembly Bill 85 (AB 85) was signed into law, which suspended the use of California net operating losses and
limited the use of California research tax credits for tax years beginning in 2020 and before 2023, although California legislation enacted in early February
2022 ends the suspension and limitation for tax year 2022. 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  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. The foregoing items could increase our future tax expense, change our future intentions regarding reinvestment of foreign
earnings,  and  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  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
revenue  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, including with regard to liquid biopsy assays such as those designed to
detect  or  quantify  MRD  or  recurrence  in  patients  previously  diagnosed  with  cancer.  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.  In  order  to  avoid  liability  related  to  an  allegation  of
infringement of these third-party patents, we may find it necessary or prudent to initiate

47

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 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.

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  or  potential  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.

48

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.

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  2041.  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.

49

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.

50

 
 
 
 
 
 
 
 
 
 
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,  providing  additional  methods  for  others  to  challenge  our
patents. 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 or the products of our competitors.
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 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, 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.

51

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.

52

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.

53

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

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.

54

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, cash equivalents and short-term investments will be sufficient
to meet our anticipated cash requirements for at least the next 12 months, rising costs and interest rates due to inflation or other economic conditions may
cause our capital expenditures and operating expenses to increase more than expected, and we cannot assure you that we will generate sufficient revenue
from commercial sales to adequately fund our operating needs or achieve or sustain profitability. If we are unable to raise additional funding on acceptable
terms, or at all, or if we consume our existing capital more quickly than expected, it could negatively impact our ability to retain and attract employees and
our competitive position, business, financial condition, results of operations, and prospects will be adversely affected.

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.

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 revenue 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  revenue  or
earnings forecasts that we may provide.

55

 
 
 
 
 
 
 
 
 
 
 
 
 
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 revenue from quarter to quarter. For example, we often see fluctuations in receipt and processing
of  samples  and  revenue  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, 2021, we had 44,904,512 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, 2021 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.

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, 2021, we had federal and state net operating loss carryforwards of approximately $222.5 million and approximately $166.3
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 taxable income. 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 Sections 382 and 383 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 were suspended and limited, respectively,
for tax years beginning after 2019 but before 2023, although California legislation enacted in early February 2022 ends the suspension and limitation for tax
year 2022.

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;

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.

57

 
 
 
 
 
 
 
 
 
 
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  a  “smaller  reporting  company”  as  defined  in  the  Exchange  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  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  document  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.

58

 
 
 
 
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.

As of December 31, 2021, we were still eligible to use the scaled disclosures of a smaller reporting company, and any decision on our
part to comply only with certain reduced reporting and disclosure requirements applicable to smaller reporting companies could make
our common stock less attractive to investors.

Our status as a “smaller reporting company,” as defined in the Exchange Act, ended on December 31, 2021, because we had at least $700 million
of equity securities held by non-affiliates on June 30, 2021. Pursuant to the rules, we are still eligible to use the scaled disclosures in this Annual Report on
Form 10-K and we may choose to take advantage of exemptions from various reporting requirements applicable to other public companies but not to smaller
reporting companies, including reduced disclosure obligations regarding executive compensation in our periodic reports and annual report on Form 10-K.

We cannot predict if investors will find our common stock less attractive if we choose to rely on any of the exemptions afforded smaller reporting
companies in this filing. 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.

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.

If we fail to maintain effective internal control over financial reporting in the future, the accuracy and timing of our financial reporting
may be adversely affected.

Assessing  our  processes,  procedures  and  staffing  in  order  to  maintain  and  improve  our  internal  control  over  financial  reporting  is  an  ongoing
process. For the year ended December 31, 2020, management became obligated to comply for the first time with Section 404 of the Sarbanes-Oxley Act of
2002  (SOX),  which  requires  issuing  a  report  that  assesses  the  effectiveness  of  our  internal  control  over  financial  reporting.  Also,  for  the  year  ended
December 31, 2021, an attestation report relating to the effectiveness of our internal control over financial reporting has been issued for the first time by our
external auditor, Deloitte & Touche LLP.

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, 2021, we had approximately
$3.8 million in customer deposits, including $3.3 million from one customer. However, as of that date, we had $287.1 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, reduces
the level of services that it expects to receive, or we determine that a prepayment is no longer necessary, we will repay that customer’s deposit. 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.

Item 2. Properties.

Our corporate headquarters are located in Menlo Park, California, and comprise approximately 46,000 square feet of space, pursuant to a lease
that expires in 2027 (14,710 square feet of such space is under a separate lease that expires at the end of 2022). This lease includes an option to extend for
an additional three years, at market rates that prevail at the time of our election to extend. Our CLIA-certified and CAP-accredited laboratory is located in this
facility.

In  August  2021,  we  announced  that  we  will  relocate  our  corporate  headquarters  from  Menlo  Park  to  a  new  facility  in  Fremont,  California.  We
signed a 13.5-year lease that expires in 2035 for the 100,000 square foot facility. This lease includes two options to extend the term for a period of five-years
per option at market rates that prevail at the time of our election to extend. The new facility is intended to allow for expansion of our CLIA-certified and CAP-
accredited laboratory as well as provide additional space for our growing workforce.

We believe that our facilities are sufficient to meet our current and foreseeable future needs. We also believe we will be able to obtain additional

space, as needed, on commercially reasonable terms.

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 18, 2022, there were approximately 71 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.

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

Personalis’ strategy is to develop some of the world’s most advanced genetic tests for cancer. Today our tests are routinely used by many of the
largest oncology-focused pharmaceutical companies for analysis of patient samples from their clinical trials. More recently, we have also begun to work with
a growing number of leading cancer centers for clinical diagnostic use of our tests. We believe that adoption and publication by these key opinion leaders will
develop  an  advanced  standard  of  care  for  cancer  patients  and  eventual  broad  use  in  a  community  hospital  setting.  We  believe  that  our  tests  can
meaningfully  improve  outcomes  for  cancer  patients,  and  we  estimate  that  the  market  opportunity  for  our  tests  for  therapy  selection  and  monitoring  is
approximately $30 billion in the U.S.

In December 2021, we launched NeXT Personal, a next-generation, tumor-informed liquid biopsy assay designed to detect and quantify MRD and
recurrence in patients previously diagnosed with cancer. NeXT Personal is designed to deliver industry-leading MRD sensitivity down to the 1 part-per-million
range, an approximately 10- to 100-fold improvement over other available technologies. NeXT Personal leverages whole genome sequencing of a patient’s
tumor to identify up to 1,800 specially-selected somatic variants that are subsequently used to create a personalized liquid biopsy panel for each patient. We
believe this enables earlier detection across a broader variety of cancers and stages, including typically challenging early stage, low mutational burden, and
low-shedding cancers. NeXT Personal is also designed to simultaneously detect and quantify clinically relevant mutations in ctDNA that may be used in the
future to help guide therapy, when cancer is detected. These include known targetable cancer mutations, drug resistance mutations, and new variants which
can emerge and change over time, especially under therapeutic pressure. We consider this approach not just “tumor-informed”, but “comprehensively tumor-
informed”. Our ultimate goal is not just to detect cancer, but to provide key information over the entire course of the patient’s disease. We believe this can be
better for patients, more informative for pharmaceutical customers, and a larger business opportunity for us.

Our  strategy  is  to  work  with  world-class  medical  institutions.  To  that  end,  in  the  fourth  quarter  of  2021,  we  announced  a  collaboration  with  the
Mayo Clinic and in the first quarter of 2022, we announced one with the Moores Cancer Center at UC San Diego Health. In these collaborations, we provide
clinical  diagnostic  testing  and  research  sequencing  and  analysis  services  using  our  tissue-based  NeXT  Dx  test.  We  have  begun  to  test  clinical  patient
samples and are excited about the opportunity to work with these renowned cancer centers. If we achieve a favorable reimbursement decision for our NeXT
Dx test from MolDx, we may also generate revenue in the future from some of these collaborations. Given the advanced nature of our NeXT Dx test, we
believe  it  is  a  good  fit  for  high-end  cancer  centers,  which  have  a  dual  mandate  for  both  clinical  care  and  research.  If  these  key  opinion  leaders  have  a
positive experience using our tests, we are optimistic that this will also support broader use of our platform by other clinicians in the future.

We  have  the  capacity  to  sequence  and  analyze  approximately  200  trillion  bases  of  DNA  per  week  in  our  facility.  We  believe  that  capacity  is
already larger than 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, NeXT Dx Test and NeXT Personal offerings. To date, we have sequenced more than 235,000 human samples, of
which more than 145,000 were whole human genomes.

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 VA MVP, which has enabled us to innovate, scale our operational infrastructure, and
achieve greater efficiencies in our lab. The VA MVP is the largest population sequencing effort in the United States and we have delivered over 140,000
whole  human  genome  sequence  datasets  to  the  VA  MVP  to  date.  The  cumulative  value  of  task  orders  received  from  the  VA  MVP  since  inception  is
approximately $186 million, $178.1 million of which we had recognized as revenue as of December 31, 2021. In September 2021, we received a task order
from the VA MVP with a value of up to approximately $9.7 million, which was significantly less than in prior years. At that time, we expected the reduced
order amount was to be followed by a formal RFP process and a potential new contract to be awarded sometime late in the third quarter of 2022. However,
recent discussions with our contacts at the VA MVP indicate that there will be no RFP process in 2022. Accordingly, we do not expect to receive any new
orders from the VA MVP this year nor to recognize any revenue from the VA MVP beyond the current order and contract. Unless we receive an additional
task order and/or enter into a new services agreement with the VA MVP with a value comparable to that of our current contract and historical contracted
orders, our revenue from the VA MVP is expected to decline significantly in 2022 and future periods. Given the strong growth we have already experienced
in our oncology business in 2021, and the large market opportunity we see in this space, we plan to focus primarily on cancer as we go forward.

In August 2021, we announced that we will relocate our corporate headquarters from Menlo Park to a new facility in Fremont, California and we
plan  to  beginning  moving  into  it  in  the  third  quarter  of  this  year.  We  signed  a  13.5-year  lease  for  the  100,000  square  foot  facility,  which  is  approximately
double the amount of space in our current Menlo Park location. The new facility is intended to allow for expansion of our laboratory for clinical testing to
support biopharma customers and clinical diagnostic testing. In addition, the new space is intended to support the expansion of research and development
efforts  to  bring  leading  edge  products  and  services  to  the  marketplace.  The  new  facility  will  also  provide  more  office  space  for  our  selling,  general  and
administrative workforce.

Our operations have been impacted by the ongoing COVID-19 pandemic. For example, the previous shelter-in-place order 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  return  in  similar  or  more  stringent  form,  they  may
continue to cause such effects on our operations. The COVID-19 pandemic has also disrupted, and may continue to 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  and  vaccines.  We  use  such  consumables  in  our  operations,  and  we  have  faced,  and  may  face  in  the  future,  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  prior  year  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.

While authorities in many areas have lifted or relaxed pandemic-related restrictions, in some cases they have subsequently re-imposed various
restrictions after observing an increased rate of COVID-19 cases as the global COVID-19 pandemic continues to rapidly evolve and to present serious health
risks. There is no guarantee when or if all such restrictions and recommendations 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. The full extent of the impact of the COVID-19 pandemic on
our  business,  operations  and  plans  remains  uncertain  and  will  depend  on  future  developments  that  cannot  be  predicted  at  this  time.  Such  developments
include the continued spread of the Omicron variant in the U.S. and other countries and the potential emergence of other SARS-CoV-2 variants that may
prove especially contagious or virulent, the ultimate duration of the pandemic and the resulting impact on our business and other third parties with whom we
do business, and the effectiveness of actions taken globally to contain and treat the disease.

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 revenue
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 revenue, 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 revenue and cost 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  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  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 new products and additional capabilities in the past two years, including 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),  and  NeXT  Personal  (liquid  biopsy  offering  for  personalized  tumor  tracking  for
patients).  We  are  currently  investing  in  the  development  of  future  new  product  offerings,  including  NeXT  CDx  (diagnostic  test)  and  NeXT
Database (comprehensive tumor immune-genomics database). We are also collaborating with key opinion leaders from cancer centers, such
as  Mayo  Clinic  and  UC  San  Diego  Moores  Cancer  Center,  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.

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  revenue  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

Revenue

We derive our revenue 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 revenue is primarily generated through contracts with companies in the pharmaceutical industry, healthcare organizations, and government
entities. Our ability to increase revenue 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. We sell through a small direct sales force.

Since  2018,  we  derived  a  substantial  portion  of  our  revenue  from  sales  of  our  DNA  sequencing  and  data  analysis  services  to  the  VA  MVP.
However, we do not anticipate deriving such substantial portions of our revenue from the VA MVP in future periods. 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  revenue  to  date  has  been

derived from sales in the United States.

Costs and Expenses

Cost of Revenue

Cost  of  revenue  consists  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 cost of revenue to increase as our revenue grows, and in the short term cost of revenue may outpace revenue growth as we invest in expanding our
laboratory  capacity,  including  additional  costs  associated  with  our  future  laboratory  in  Fremont,  California.  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
processing 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 costs in the period in which they are incurred. We expect to increase our research and development

expenses as we continue to develop new products and incur additional costs associated with our future headquarters in Fremont, California.

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 costs 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 expect general and administrative expenses to increase as we scale our operations and incur additional costs associated with ramping up our
new headquarters facility in Fremont, California.

64

 
Interest Income and Interest Expense

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”). Since the first quarter of 2020, our interest income has been adversely impacted by declines in yields on debt securities. Interest expense in 2021 is
the  recognition  of  imputed  interest  on  noninterest  bearing  loans.  Interest  expense  in  2019  and  prior  years  consisted  of  cash  and  non-cash  interest  costs
related to previously outstanding loans.

Loss on Debt Extinguishment

We  incurred  a  loss  on  debt  extinguishment  in  2018  resulting  from  changes  in  the  maturity  dates  of  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, and realized gains or losses associated with sales
of marketable securities. In 2019, other income (expense), net also consisted of changes in fair value of a convertible preferred stock warrant liability. We
expect our foreign currency gains and losses to continue to fluctuate in the future due to changes in foreign currency exchange rates.

The decrease of $10.5 million in revenue from the VA MVP in 2021 was primarily due to a decrease in the volume of samples we tested in the
period. As of December 31, 2021, we had a remaining backlog of $7.6 million under our current contract with the VA MVP, including the task order received
in September 2021. We expect to convert such amount into revenue during the first three quarters of 2022.

The recognition of significant revenue from the VA MVP in future periods after the completion of our current backlog is contingent on receipt of a
new contract. The VA MVP may not award us a new contract. Further, the value of any such potential new contract 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 any such new contract may change such that
we  are  unable  to  serve  the  VA  MVP  in  the  future.  The  task  order  received  in  September  2021  had  a  value  of  up  to  approximately  $9.7  million,  which
represents  a  substantial  decline  compared  to  historical  contracted  orders.  At  that  time,  we  expected  the  reduced  order  amount  was  to  be  followed  by  a
formal RFP process and a potential new contract to be awarded sometime late in the third quarter of 2022. However, recent discussions with our contacts at
the VA MVP indicate that there will not be an RFP process in 2022. Accordingly, we are not planning on receiving any new orders from the VA MVP this year
or expecting to recognize any revenue beyond the current order and contract. Unless we receive an additional task order and/or enter into a new services
agreement  with  the  VA  MVP  with  a  value  comparable  to  that  of  our  current  contract  and  historical  contracted  orders,  our  revenue  from  the  VA  MVP  will
decline significantly in 2022 and future periods.

All other customers

The  increase  of  $17.3  million  in  revenue  from  all  other  customers  in  2021  was  driven  primarily  by  strong  demand  from  large  pharmaceutical
customers for our NeXT Platform products, which resulted in an increase in the volume of samples we tested during 2021. Revenue from Natera contributed
$8.6  million  of  the  increase  due  to  increased  sample  receipts  under  our  agreement  to  provide  advanced  tumor  analysis  for  use  in  Natera’s  MRD  testing
offerings. Revenue derived from our NeXT Platform products, which includes revenue from Natera, was $27.9 million in 2021, compared to $8.2 million in
2020, an increase of $19.7 million.

Based on the relatively large dollar value of orders received from all other customers throughout fiscal 2021, we anticipate that revenue from all

other customers will make up the majority of our total revenue in fiscal year 2022.

Cost of revenue

The  decrease  in  cost  of  revenue  in  2021,  despite  a  revenue  increase  in  the  same  period,  was  primarily  due  to  favorable  customer  mix  and
efficiencies within our laboratory operations. Raw materials costs were lower, relative to revenue, for non-VA MVP customer orders, resulting in favorable
customer  mix  in  2021.  We  also  observed  more  efficient  sample  processing  overall  in  2021,  including  less  labor  and  overhead  required  per  sample
processed, which was favorable for both VA MVP and non-VA MVP orders.

The cost components related to the $4.7 million decrease in cost of revenue in 2021 were a $3.2 million decrease in raw materials costs due to
favorable customer mix, a $3.1 million decrease in indirect costs due to a higher utilization of our laboratory for research and development activities, and a
$0.3 million decrease in the cost of laboratory supplies and consumables, partially offset by a $1.1 million increase in labor costs as a result of increased
headcount, and a $0.8 million increase in depreciation and maintenance on lab equipment.

Research and development

The $20.7 million increase in research and development in 2021 was primarily due to development of new products and lab automation efforts and
consisted of a $12.1 million increase in personnel-related costs primarily related to increased headcount, a $5.1 million increase in sample processing costs
incurred in our laboratory for new product development, a $2.0 million increase in IT and fixed facilities costs, a $1.0 million increase in depreciation and
maintenance on research and development equipment, and a $0.5 million increase in consulting fees.

Selling, general and administrative

The $14.0 million increase in selling, general and administrative in 2021 was primarily due to a $8.6 million increase in personnel-related costs
related  to  increased  headcount,  a  $2.6  million  increase  in  professional  services  (including  corporate  insurance,  audit  fees,  and  legal  expenses),  a  $1.6
million increase in rent expense primarily related to our new Fremont facility, and a $1.2 million charge in connection with the modification of stock options
held by two non-employee board members.

The decrease in interest income in 2021 was driven by declines in yields on debt securities, partially offset by higher average cash and investment
balances subsequent to our follow-on equity offerings in August 2020 and January 2021. Interest expense in 2021 is the recognition of imputed interest on
noninterest bearing loans.

From our inception through December 31, 2021, we have funded our operations primarily from $279.0 million in net proceeds from our follow-on
equity offerings in August 2020 and January 2021, $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, 2021, we had cash and cash equivalents in the amount
of $105.6 million and short-term investments in the amount of $181.5 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. We filed a prospectus supplement in January 2022 pursuant to which we could offer and sell
additional  shares  of  our  common  stock  up  to  an  aggregate  amount  of  $100.0  million  through  an  at-the-market  offering  program.  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.

As of December 31, 2021, cash and cash equivalents held by foreign subsidiaries was $2.1 million. Our intent is to indefinitely reinvest funds held
outside the United States and our current plans do not demonstrate a need to repatriate them to fund our domestic operations. However, if in the future, we
encounter a significant need for liquidity domestically or at a particular location that we cannot fulfill through borrowings, equity offerings, or other internal or
external sources, or the cost to bring back the money is not significant from a tax perspective, we may determine that cash repatriations are necessary or
desirable.  Repatriation  could  result  in  additional  material  taxes.  These  factors  may  cause  us  to  have  an  overall  tax  rate  higher  than  other  companies  or
higher than our tax rates have been in the past.

During  2021, cash used in operating activities of  $70.8  million  was  a  result  of  $65.2  million  of  net  loss  and  a  net  negative  change  in  operating
assets  and  liabilities  of  $31.1  million  (of  which  $17.1  million  was  related  to  reductions  in  outstanding  customer  prepayments  as  we  fulfilled  the  related
revenue contracts and $12.1 million due to an increase in accounts receivable), partially offset by non-cash adjustments to net income of $25.5 million (the
most significant non-cash expenses were $14.4 million of stock-based compensation and $6.0 million of depreciation and amortization).

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

During 2021, cash used in investing activities was $60.1 million due to net purchases of short-term investments of $49.0 million and $11.1 million
in  payments  for  property  and  equipment.  Cash  provided  by  financing  activities  of  $169.7  million  during  the  same  period  consisted  of  $162.3  million  net
proceeds from our January 2021 follow-on offering, $5.2 million proceeds from loans, and $4.4 million proceeds from stock option exercises and purchases
under our Employee Stock Purchase Plan (“ESPP”), partially offset by $1.9 million repayments of loans and $0.3 million of offering costs.

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 in
payments  for  property  and  equipment.  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, $4.2 million proceeds from stock option exercises and purchases under our ESPP, partially offset by $0.4
million of offering costs.

Material Cash Requirements

Our  material  cash  requirements  in  the  short-  and  long-term  consist  primarily  of  capital  expenditures,  variable  costs  of  revenue,  operating
expenditures,  property  leases,  and  other.  We  plan  to  fund  our  material  cash  requirements  with  our  existing  cash  and  cash  equivalents  and  short-term
investments, which amounted to $287.1 million as of December 31, 2021, as well as anticipated cash receipts from customers.

Capital expenditures. We expect to increase capital expenditures in future periods to support our global growth initiatives. Such expenditures are
expected  to  consist  primarily  of  facility  renovations  and  improvements,  laboratory  equipment,  and  computer  equipment.  We  currently  expect  capital
expenditures to be between $55 and $65 million in 2022 and between $10 and $15 million in each of the next two fiscal years. In connection with our new
headquarters and laboratory facility in Fremont, California, we expect to

68

 
spend between $45 and $50 million (net of expected landlord reimbursements) in combined leasehold improvements, renovations, administrative, and other
costs through the end of 2022. This is the reason for greater expected capital expenditures in 2022 as compared to the following two years.

Variable costs of revenue. From time to time in the ordinary course of business, we enter into agreements with vendors for the purchase of raw
materials,  laboratory  supplies  and  consumables  to  be  used  in  the  sequencing  of  customer  samples.  However,  we  generally  do  not  have  binding  and
enforceable purchase orders beyond the short term, and the timing and magnitude of purchase orders beyond such period is difficult to accurately project.
Another primary use of cash within variable costs of revenue relates to paying our workforce. We currently expect spend to decrease in 2022 but increase in
years thereafter to support revenue growth.

Operating  expenditures.  Our  primary  use  of  cash  relates  to  paying  employees,  spend  on  professional  services,  spend  related  to  research  and
development  projects,  and  other  costs  related  to  our  research  and  development,  selling,  general  and  administrative  functions.  We  currently  expect  to
increase our spend in these areas to support our business growth in 2022. On a long-term basis, we manage future cash requirements relative to our long-
term business plans.

Property leases. Our noncancelable operating lease payments were $84.6 million as of December 31, 2021. 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.”

Other.  During  the  second  quarter  of  2021,  we  entered  into  two  noninterest  bearing  loans  to  finance  the  purchase  of  $5.6  million  of  computer
hardware, internal use software licenses, and related ongoing support. We made payments of $1.86 million in 2021. We are required to make payments of
$1.86 million in each of 2022 and 2023. Further discussion of this transaction can be found in Part II, Item 1 of this Form 10-K in the Notes to Consolidated
Financial Statements in Note 6, “Loans.”

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, 2021, we had approximately
$3.8 million in customer deposits, including $3.3 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, reduces the level of services that it expects to receive, or we determine that a prepayment is no longer necessary, we
will repay that customer’s deposit. We do not expect such repayments to require material amounts of cash.

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, revenue, 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  revenue  recognition,  stock-based
compensation,  and  leases  have  the  greatest  potential  impact  on  our  consolidated  financial  statements.  Therefore,  we  consider  these  to  be  our  critical
accounting policies and estimates.

Revenue Recognition

We generate our revenue 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  generally  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, except in limited instances. We do not offer retrospective
discounts

69

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 has determined that customers obtain
control  when  the  sequencing  and  data  analysis  service  results  are  delivered  to  customers.  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 revenue upon providing sequencing and data analysis services.

All of our revenue and trade receivables are generated from contracts with customers and substantially all of our revenue is derived from U.S.

domestic operations.

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

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. We determine the grant-date fair value of options using the Black-Scholes option-pricing model, except for certain performance-based awards for
which  an  alternative  valuation  method  may  be  used.  We  determine  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,
our ESPP is deemed to be a compensatory plan and therefore is included in stock-based compensation expense.

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,  expected  volatility  was  estimated  based  on  an  average  historical  stock  price
volatility of a peer group of publicly traded companies as we did not have sufficient trading history for our own common stock. 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 award.

Incremental Borrowing Rate

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  (the  incremental  borrowing  rate),  unless  the  rate  implicit  in  the  lease  is  readily
determinable.

70

 
 
 
 
In August 2021, we entered into a 13.5-year lease for our new corporate headquarters. We estimated our incremental borrowing rate as the rate
implicit in the lease was not readily determinable. To determine the incremental borrowing rate, we estimated our credit rating by comparing certain financial
ratios and metrics of the Company to those of other issuers with publicly available credit ratings from Standard & Poor’s (S&P). We then adjusted yields from
publicly traded corporate bonds of companies of similar size and credit rating over a term approximating the term of our lease for the nature of the collateral.
Our concluded incremental borrowing rate for this lease was 5.8%, which resulted in a lease liability and right-of-use asset of $44.7 million.

JOBS Act Accounting Election

Prior  to  December  31,  2021,  we  were  a  smaller  reporting  company  and  eligible  to  take  advantage  of  the  same  reduced  disclosures  that  an
emerging  growth  company,  as  defined  in  the  Jumpstart  Our  Business  Startups  Act  (the  “JOBS  Act”),  could  avail  itself  to.  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 had irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and
therefore, are subject to the same new or revised accounting standards as other public companies that are not smaller reporting companies or 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 provider of advanced genetic tests for cancer. The Company also
provides sequencing and data analysis services to support population sequencing initiatives, which accounts for the majority of its revenue. The Company’s
genetic  tests  for  cancer  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 in the
United  States  and  Europe.  In  June  2020,  the  Company  began  partnering  with  a  clinical  genomics  and  life  sciences  company  headquartered  in  China  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 its 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.

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 revenue and expenses during the reporting period. The estimates include, but are not limited to, useful lives assigned to long-
lived assets, discount rates for lease accounting, the valuation of stock options, 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 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).

78

 
Follow-On and At-the-Market Equity Offerings

On August 14, 2020, the Company completed a follow-on equity 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  $117.5  million  after  deducting  underwriting  discounts,  commissions.  The
Company also incurred $0.4 million of offering costs, including legal, accounting, printing and other offering-related costs.

On  January  29,  2021,  the  Company  completed  a  follow-on  equity  offering  in  which  it  issued  and  sold  3,950,000  shares  of  its  common  stock  at  a
public offering price of $38.00 per share. The Company 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  of
$21.2 million after deducting underwriting discounts and commissions. The Company also incurred $0.3 million of offering costs, including legal, accounting,
printing and other offering-related costs.

On December 30, 2021, the Company entered into an At-the-Market Sales Agreement (the “Sales Agreement”) with BTIG, LLC (“BTIG”) under which
it may offer and sell its common stock having aggregate sales proceeds of up to $100.0 million from time to time through BTIG as its sales agent. BTIG will
use commercially reasonable efforts to sell the Company’s common stock from time to time, based upon instructions from the Company (including any price,
time or size limits or other customary parameters or conditions the Company may impose). The Company will pay BTIG a commission of up to 3% of the
gross sales proceeds of any common stock sold through BTIC under the Sales Agreement. The Company is not obligated to make any sales of common
stock under the Sales Agreement. No shares of the Company’s common stock have been offered or sold under the Sales Agreement.

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 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, 2021 and 2020. The Company had no bad debt expense in 2021 and 2020. During the year ended December 31, 2019,
bad debt expense was $0.1 million and included in selling, general and administrative expenses.

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

Natera, Inc.
Pfizer Inc.

Revenue Recognition

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 revenue 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.

Cost of Revenue

Cost  of  revenue  consists  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 (“IT”) 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 processing samples for research purposes, depreciation and maintenance on equipment, and allocated facilities and IT 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 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 (the “ESPP”) is deemed to be a compensatory plan and therefore is included in
stock-based compensation expense.

80

 
 
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 contractual expiration date is used as the expected term
under this method. For awards with multiple vesting tranches, the assumed period for each tranche is computed separately and then averaged together to
determine the expected term for the award.

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.

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.

The Company considers undistributed earnings of its foreign subsidiaries to be indefinitely reinvested and, accordingly, no U.S. income taxes have

been provided thereon.

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.

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  value  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.

82

 
 
 
 
 
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

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

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, 2021, 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 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 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. The Company has also elected to include
expenses related to leases with a term of one month or less in the short-term lease cost disclosure.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In  December  2019,  the  FASB  issued  Accounting  Standards  Update  (“ASU”)  2019-12,  Income  taxes  (Topic  740):  Simplifying  the  Accounting  for
Income  Taxes,  which  simplifies  the  accounting  for  income  taxes  by  removing  certain  exceptions  to  the  general  principles  in  Topic  740  and  clarifies  and
amends  the  existing  guidance.  The  new  standard  is  effective  January  1,  2021  and  the  Company  has  adopted  it  effective  December  31,  2020.  The  new
standard did not have a material impact on the Company’s consolidated financial statements.

New Accounting Pronouncements Not Yet Adopted

In  June  2016,  the  FASB  issued  ASU  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 2019, the FASB delayed the effective date for Topic 326 as applicable to smaller reporting companies to the
first quarter of 2023. While the Company will no longer qualify as a smaller reporting company starting in the first quarter of 2022, the delayed effective date
still  applies  to  the  Company.  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

Prior to December 31, 2021, the Company was 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 had irrevocably elected not to avail itself of this exemption from new
or revised accounting standards, and therefore, the Company was subject to the same new or revised accounting standards as other public companies that
are not emerging growth companies.

Contract Assets and Liabilities

Contract assets as of December 31, 2021 and 2020 were immaterial.

The Company's contract liabilities consist of consideration received from customers in excess of revenue recognized and are presented as current

liabilities in the consolidated balance sheets.

The balance of contract liabilities was $4.0 million and $21.0 million as of December 31, 2021 and 2020, respectively. Revenue recognized in 2021,
2020,  and  2019  that  were  included  in  the  contract  liability  balance  at  the  beginning  of  each  reporting  period  were  $19.1  million,  $33.8  million,  and
$35.4 million, respectively.   

Revenue allocated to remaining performance obligations represent contracted revenue that has not yet been recognized (“contracted not recognized
revenue”),  which  include  VA  MVP  contract  liabilities  and  amounts  that  will  be  invoiced  and  recognized  as  revenue  in  future  periods.  Contracted  not
recognized revenue was $7.6 million as of December 31, 2021, which the Company expects to recognize as revenue within the next 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.

Realized gains or losses on marketable debt securities are immaterial 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,  2021,  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,  2021  have  maturities  due  in  one  year  or  less,  except  for  debt  securities  with  an

aggregate cost basis of $40.5 million and fair value of $40.3 million that have maturities ranging from 13 months to 21 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.

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  bore  an  interest  rate  of  prime,  plus
6.75%. The Revolving Loan also had a 5.5% end of term loan payment on the highest outstanding principal amount. The Revolving Loan required 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 for the year ended December 31, 2019 was $0.2 million. 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.

Equipment and Software Loans

In April 2021, the Company entered into a payment agreement with a financing entity to finance the purchase of $2.4 million of certain internal use
software licenses and related software maintenance from a vendor. The financing entity and vendor are not related. The Company is obligated to repay the
financed amount in three equal payments of $0.8 million in May 2021, May 2022, and May 2023. The payment agreement is noninterest bearing and the
Company concluded that such interest rate (zero) did not represent fair and adequate compensation to the financing entity for the use of the related funds.
Accordingly, the Company approximated the rate at which it could obtain financing of a similar nature from other sources at the date of the transaction. The
resulting  imputed  interest  rate  was  7%  and  was  used  to  establish  the  present  value  of  the  payment  agreement.  The  discount  is  recognized  as  interest
expense in the consolidated statements of operations over the life of the payment agreement.

In  April  2021,  the  Company  entered  into  another  payment  agreement,  with  the  same  financing  entity,  to  finance  the  purchase  of  $3.1  million  of
certain computer hardware and related hardware maintenance. The Company is required to pay three equal payments of $1.0 million in July 2021, June
2022, and June 2023. The nature of this agreement and resulting accounting treatment are the same as the payment agreement described in the preceding
paragraph.

The total initial present value of the payment agreements was $5.2 million and presented as proceeds from loans in the consolidated statements of
cash flows. Such proceeds were used to purchase equipment, software, and related maintenance and are reflected as cash outflows in the investing and
operating  activities  sections  in  the  consolidated  statements  of  cash  flows.  Repayments  are  presented  as  financing  cash  outflows  in  the  consolidated
statements of cash flows. Interest expense for the year ended December 31, 2021 was $0.2 million. Amounts outstanding under the payment agreements
are as follows (in thousands):

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  term  of  the  lease  through  November  30,  2027.  The  lease  includes  an
option to extend the term for a period of three years with rent payments equal to then current fair market rent 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  May
2021, the Company amended the lease to expand the premises subject to the lease to include an additional 14,710 square feet of space (the “Expansion
Lease”). The Expansion Lease expires on December 31, 2022 and has no option to extend the term.

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  option  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.

In August 2021, the Company entered into a noncancelable operating lease for approximately 100,000 square feet of space in Fremont, California to
be used as the Company’s future corporate headquarters and expanded laboratory facility. The lease term is 13.5 years and commences in June 2022. The
Company  gained  early  access  to  the  premises  upon  entering  the  lease  for  the  purpose  of  constructing  and  installing  tenant  improvements,  for  which  the
landlord has agreed to contribute up to approximately $15.5 million. Such contributions become payable only upon approval by the landlord of applications
for payment and are accounted for as lease incentives once the Company has incurred costs and the amounts qualify for reimbursement by the landlord.
The lease incentives are then recognized prospectively over the remainder of the lease term. The lease expires on November 30, 2035 and includes two
options to extend the term for a period of five-years per option with rent payments equal to then current fair market rent for the space. The

The  Company  also  has  a  noncancelable  operating  lease  for  approximately  5,100  square  feet  of  space  in  Shanghai,  China  used  for  its  China

operations, which expires on June 30, 2024, as well as various other short-term leases.

As  of  December 31, 2021, the Company’s operating  leases  had  a  weighted-average  remaining  lease  term  of  12.2  years  and  a  weighted-average
discount  rate  of  6.6%.  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, 2021 were as follows (in thousands):

ended December 31, 2021, 2020 and 2019, was $3.3 million, $1.7 million and $1.2 million, respectively. Right-of-use assets obtained in exchange for new
operating lease liabilities, during 2021, 2020 and 2019, were $46.5 million, $9.8 million and $2.8 million, respectively.

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.

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, 2021 and December 31, 2020 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 vested and exercisable as of December 31, 2021

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 $14.27 on December 31, 2021 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  $13.14,  $7.17,  and  $8.00  per  share  for  the  years  ended  December  31,  2021,
2020,  and  2019,  respectively.  As  of  December  31,  2021,  the  unrecognized  stock-based  compensation  of  unvested  options  was  $18.1  million,  which  is
expected to be recognized over a weighted-average period of 2.3 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 was estimated using the following weighted-average assumptions:

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. During the
last quarter of 2020, the Company’s average market capitalization was equal to or greater than $1 billion over a 30 calendar day period and the PSO vested
in full.

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- or four-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 $14.27 on December 31, 2021.
As of December 31, 2021, the unrecognized stock-based compensation cost of unvested RSUs was $25.1 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,  2021,  2020  and  2019,  128,289,  164,164  and  77,684  shares  of  common  stock  were  purchased  under  the
ESPP, respectively. The following assumptions were used to calculate the stock-based compensation for each stock purchase right granted under the ESPP:

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”). The Term Loan was repaid in full in September 2018. In connection with the
Term Loan, 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 were 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, 2021, 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. Basic and Diluted Net Loss Per Common Share

Basic net loss per common share is computed by dividing the net loss by the weighted-average number of common shares outstanding during the
period. Diluted net loss per common share is computed using net loss and the weighted-average number of common shares outstanding plus potentially
dilutive common shares outstanding during the period. Potentially dilutive common shares include the assumed exercise of outstanding in-the-money stock
options and common stock warrants, assumed release of outstanding RSUs, and assumed issuance of common stock under the ESPP using the treasury
stock method.

The  following  table  sets  forth  the  computation  of  basic  and  diluted  net  loss  per  share  attributable  to  common  stockholders  (in  thousands,  except

share and per share amounts):

The Company incurred net losses in the periods presented, and as a result, potential common shares from stock options, common stock warrants,

inclusion would have been anti-dilutive. The following table sets forth the potentially dilutive shares excluded from the computation of diluted net loss per
common share because their effect was anti-dilutive:

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, of which $0.3 million has been paid as of December 31, 2021. 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

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 $24.8 million and $16.8 million during the years ended December 31, 2021 and 2020, respectively.

Net Operating Loss and Tax Credit Carryforwards

As  of  December  31,  2021,  the  Company  had  a  net  operating  loss  carryforward  for  federal  income  tax  purposes  of  approximately  $222.5  million,
portions  of  which  will  begin  to  expire  in  2031.  The  Company  had  a  total  state  net  operating  loss  carryforward  of  approximately  $166.3  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,  2021,  the  Company  has  federal  credits  of  approximately  $6.1  million,  which  will  begin  to  expire  in  2031  and  state  research

credits of approximately $6.0 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 assets, 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):

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, 2021, 2020, and 2019, no interest or penalties were required to be recognized relating to unrecognized tax
benefits.

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, 2021 and 2020,
the related consolidated statements of operations, comprehensive loss, redeemable convertible preferred stock and stockholder's equity (deficit) and cash
flows, for each of the three years in the period ended December 31, 2021, 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, 2021 and 2020, and the
results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles
generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's
internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by
the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 24, 2022, expressed an unqualified opinion on the
Company's internal control over financial reporting.

Basis for Opinion

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

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

Critical Audit Matters

Critical audit matters are matters arising from the current-period audit of the financial statements that were communicated to the audit committee and that (1)
relate to accounts or disclosures that are material to the financial statements and (2) involve especially challenging, subjective, or complex judgments. We
determined that there are no critical audit matters.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Personalis, Inc. and subsidiaries (the “Company”) as of December 31, 2021, based on criteria
established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria
established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated
financial statements as of and for the year ended December 31, 2021 of the Company and our report dated February 24, 2022, expressed an unqualified
opinion on those financial statements.

Basis for Opinion

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

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

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

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, 2021, 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,  2021  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,  2021,  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. The effectiveness of our internal control over financial reporting as of December
31, 2021 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report that is included in Part II,
Item 8, of this Annual Report on Form 10-K.

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.

Item 9B. Other Information.

Compensatory Arrangements of Certain Officers

On February 16, 2022 and February 21, 2022, the compensation committee of the board of directors of the Company approved the amendment and
restatement of the terms of executive severance agreements for Messrs. West and Tachibana and Dr. Chen, each dated February 23, 2022 (collectively, the
“A&R Executive Severance Agreements”).

Provisions that were amended in the A&R Executive Severance Agreement with Mr. West (the “West Severance Agreement”), include, among other

things:

•

•

In the event that there is a “separation from service” (as defined in the West Severance Agreement), the period to receive payment of COBRA
health  insurance  premiums  will  be  shortened  to  the  earlier  of  (i)  12  months  or  (ii)  the  date  upon  which  Mr.  West  obtains  coverage  under  a
subsequent employer’s medical plan.

In  the  event  of  a  separation  from  service  within  12  months  after  the  effective  date  of  “change  in  control”  (as  defined  in  the  West  Separation
Agreement), the vesting of each of Mr. West’s then-outstanding unvested equity compensation awards shall accelerate as to all of then-unvested
shares  subject  to  each  such  award,  or,  in  the  case  of  any  other  separation  from  service,  the  vesting  of  each  of  Mr.  West’s  then-outstanding
unvested  equity  compensation  awards  shall  accelerate  as  to  the  number  of  the  then-unvested  shares  subject  to  each  such  award  that  would
have become vested within the first 24 months following such separation from service, subject to certain conditions.

Provisions  that  were  amended  in  the  A&R  Executive  Severance  Agreements  with  each  of  Mr.  Tachibana  and  Dr.  Chen  (together,  the  “Officer

Severance Agreements”), include, among other things:

•

•

In the event that there is a “separation from service” (as defined in the Officer Severance Agreements), the period to receive payment of COBRA
health insurance premiums will be shortened to the earlier of (i) 12 months for Mr. Tachibana and 9 months for Dr. Chen or (ii) the date upon
which the executive obtains coverage under a subsequent employer’s medical plan.

In the event that there is a separation from service that is not within 12 months after a “change in control” (as defined in the Officer Severance
Agreements), the executive will be entitled to 6 months of his then current base salary, subject to certain conditions.

Appointment of Director

On  February  17,  2022,  upon  recommendation  of  the  nominating  and  corporate  governance  committee  of  the  board  of  directors,  the  board  of
directors increased the size of the board of directors from 7 to 8 members, and appointed Olivia K. Bloom, to the board of directors as a Class I director,
which  appointment  will  become  effective  on  March  1,  2022.  Ms.  Bloom’s  term  will  expire,  along  with  the  terms  of  the  other  Class  I  directors,  at  the
Company’s annual meeting of stockholders in 2023. The board of directors also appointed Ms. Bloom to serve as a member of the audit committee of the
board of directors, with such appointment effective upon her appointment to the board of directors.

There are no arrangements or understandings between Ms. Bloom and any other persons pursuant to which she was selected as a director. The
board of directors has determined that Ms. Bloom qualifies as an independent director under the independence requirements set forth under Rule 5605(a)(2)
of the Nasdaq Rules and listing standards. Additionally, there are no transactions involving the company and Ms. Bloom that we would be required to report
pursuant to Item 404(a) of Regulation S-K.

In connection with her appointment to the board of directors and the audit committee, and pursuant to the Company’s amended and restated non-
employee director compensation policy (the “Amended Personalis, Inc. Non-Employee Director Compensation Policy”), Ms. Bloom will receive annual cash
retainers for her service on the board of directors and any committee of the board of directors, an initial equity grant and annual equity grants, each in the
amounts set forth in the Company’s Amended Non-Employee Director Compensation Policy.

The company will also enter into its standard form of indemnification agreement with Ms. Bloom.

AMENDMENT NO. 1 TO LEASE

Exhibit 10.16

This AMENDMENT NO. 1 TO LEASE (“Amendment”) is dated as of this 8th day of December, 2021, by and between

ARDENWOOD VENTURES I, LLC, a Delaware limited liability company (“Landlord”), and PERSONALIS, INC., a Delaware corporation
(“Tenant”).

RECITALS

A.

Landlord and Tenant entered into that certain Lease Agreement dated as of August 24, 2021 (the “Lease”) for
premises located at 6600 Dumbarton Circle in Fremont, California, comprised of approximately 100,808 rentable square feet of floor area as
more particularly described in the Lease;

B.

Landlord and Tenant now desire to amend the Lease on the terms and conditions set forth

herein.

AGREEMENT

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged,

Landlord and Tenant hereby agree as follows:

1.
them in the Lease.

Definitions. All capitalized terms used in this Amendment but not otherwise defined shall have the meanings assigned to

2.

3.

Elevator. The first sentence of Paragraph 2 of the Work Letter is hereby amended in its entirety to read as follows:

“Tenant shall cause the Tenant Parties to construct, furnish or install all improvements, equipment or fixtures, that
Tenant deems reasonably necessary for Tenant’s intended use of the Leased Premises, including laboratory, research
and  development,  and  manufacturing  facilities,  which  may  include,  without  limitation,  a  new  freight  elevator
(collectively, the “Tenant Improvements”).”

Initial TI Budget. Paragraph 3(b)(iii) of the Work Letter is hereby amended in its entirety to read as follows:

“Prior to the TI Allowance Deadline, on or before the 30th day following submission of the application for payment,
so long as Tenant is not in monetary default, or material non- monetary default beyond the expiration of any notice
and cure periods expressly set forth in the Lease or this Work Letter, under the terms of this Work Letter or the Lease,
Landlord shall pay a share of such payment pari passu with Tenant, determined by multiplying the amount of such
payment  by  a  fraction,  the  numerator  of  which  is  the  amount  of  the  Tenant Improvement  Allowance,  and  the
denominator of which is $33,409,720, based on the “Initial TI Budget,” defined herein as the September 27, 2021
budget delivered to Landlord by Tenant, which includes reasonable detail on the estimated construction cost of  all
Tenant  Improvement  work  and  materials  for  the  entire  Leased  Premises,  and  the estimated cost of all professional
services, fees and permits in connection therewith. Tenant shall pay the balance of such payment, provided that at such
time as Landlord has paid the entire Tenant Improvement Allowance on account of such Tenant Improvement work,
all billings shall be paid entirely by Tenant. If upon completion of the Tenant Improvement work and payment in full
to the Tenant Improvement Contractor, the architect and engineer,  and  payment  in  full  of  all  fees  and  permits,  the
portion of the cost of the Tenant

1.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Improvement  work,  architects’  and  engineers’  fees,  permits  and  fees  theretofore  paid  by Landlord is less than the
Tenant  Improvement  Allowance,  Landlord  shall  reimburse  Tenant  for  costs  expended  by  Tenant  for  Tenant
Improvement work up to the amount by which the Tenant Improvement Allowance exceeds the portion of such cost
theretofore paid by Landlord, it being the intent of the parties that Tenant shall in such case be entitled to the benefit
of the entire Tenant Improvement Allowance.  Landlord shall have no obligation to advance the Tenant Improvement
Allowance to the extent it exceeds the total cost of the Tenant Improvement work. In no event shall Landlord have any
responsibility for the cost of the Tenant Improvement work in excess of the Improvement Allowance.  Landlord shall
have no obligation to make any payments to Tenant Improvement Contractor’s material suppliers or subcontractors
or  to  determine  whether  amounts  due  them  from  Tenant  Improvement  Contractor  in  connection  with  the  Tenant

Equity Compensation

Equity awards will be granted under the Company’s 2019 Equity Incentive Plan, as amended from time to time, or any
successor  equity  incentive  plan  (the  “Plan”).  All  stock  options  granted  under  the  Director  Compensation  Policy  will  be
Nonstatutory Stock Options (as defined in the Plan), with a term of ten years from the date of grant (subject to earlier termination
upon a termination of the Non-Employee Director’s Continuous Service (as defined in the 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 $125,000 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 $125,000 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 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 $82,500 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 $82,500 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

2

 
 
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.

PERSONALIS, INC.

FIRST AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

(JOHN WEST)

This  First  Amended  and  Restated  Executive  Severance  Agreement  (the  “Agreement”),  effective  as  of  February  23,
2022  amends,  supersedes  and  restates  in  its  entirety  that  certain  Executive  Severance  Agreement  by  and  between  John  West
(“Executive”) and Personalis, Inc. (the “Company”) dated June 2, 2019.  This Agreement is intended to provide Executive with
certain benefits described herein upon the occurrence of specific events.  

RECITALS

A.

The Company’s Board of Directors (the “Board”) believes it is in the best interests of the Company and its

shareholders to retain Executive and provide incentives to Executive to continue in the service of the Company.

B.

The Board further believes that it is imperative to provide Executive with certain benefits upon termination of
Executive’s  employment,  which  benefits  are  intended  to  provide  Executive  with  financial  security  and  sufficient  income  and
encouragement to Executive to remain with the Company.

C.

To  accomplish  the  foregoing  objectives,  the  Board  has  directed  the  Company,  upon  execution  of  this

Agreement by Executive, to agree to the terms provided in this Agreement.

Now  therefore,  in  consideration  of  the  mutual  promises,  covenants  and  agreements  contained  herein,  the

parties hereto agree as follows:

1.

At-Will  Employment.    Executive’s  employment  is  at-will,  which  means  that  the  Company  may  terminate
Executive’s  employment  at  any  time,  with  or  without  Cause  or  advance  notice.    Similarly,  Executive  may  resign  Executive’s
employment  at  any  time,  with  or  without  advance  notice,  and  with  or  without  Good  Reason.    Executive  shall  not  receive  any
compensation  of  any  kind,  including,  without  limitation,  equity  award  vesting  acceleration  and  severance  benefits,  following
Executive’s last day of employment with the Company, except as expressly provided herein.

2.

Benefits  Upon  Termination  of  Employment  without  Cause  or  with  Good  Reason.  If  Executive’s
employment  is  terminated  without  Cause  (as  defined  below)  (and  other  than  as  a  result  of  Executive’s  death  or  disability),  or
Executive resigns for Good Reason (as defined below), provided such termination constitutes a “separation from service” (within
the meaning of Treasury Regulation Section 1.409A-1(h), such termination a “Separation from Service”), and provided further
that Executive signs and allows to become effective a general release of all claims in favor of the Company in a form provided by
the Company (the “Release”),

1.

 
 
 
 
 
 
within sixty (60) days after Executive’s Separation from Service (the date that the Release becomes effective and may no longer
be  revoked  by  Executive  is  referred  to  as  the  “Release Date”),  then  the  Company  shall  provide  Executive  with  the  following
severance benefits (the “Separation Benefits”):

The  Company  shall  pay  Executive  cash  severance  in  an  amount  equal  to  twelve  (12)  months  of
Executive’s  then-current  base  salary,  ignoring  any  decrease  in  base  salary  that  forms  the  basis  for  Good  Reason,  less  all
applicable withholdings and deductions, paid on the Company’s first regular payroll date following the Release Date.  

(a)

(b)

Should  Executive  timely  elect  to  continue  Executive’s  medical,  dental  and/or  vision  insurance
benefits pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) or any analogous provisions of
applicable state law, the Company shall pay Executive’s COBRA premiums for Executive and Executive’s eligible dependents
(“COBRA  Premiums”)  for  a  period  of  twelve  (12)  months  following  Executive’s  Separation  from  Service  (the  “Benefits
Payment  Period”)  or,  if  earlier,  the  date  upon  which  Executive  obtains  coverage  under  a  medical  plan  by  a  subsequent
employer.  The Company’s obligation to pay any COBRA Premiums will be subject to the then-current requirements of COBRA
and  any  other  laws  affecting  the  payment  of  COBRA  premiums  by  the  Company.    Notwithstanding  the  foregoing,  if  the
Company  determines,  in  its  sole  discretion,  that  the  Company  cannot  provide  the  COBRA  Premiums  without  potentially
incurring  financial  costs  or  penalties  under  applicable  law,  the  Company  shall  in  lieu  thereof  pay  Executive  a  taxable  cash
amount,  which  payment  shall  be  made  regardless  of  whether  Executive  elects  health  care  continuation  coverage  (the  “Health
Care Benefit Payment”).  The Health Care Benefit Payment shall be paid in monthly installments on the same schedule that the
COBRA  Premiums  would  otherwise  have  been  paid  to  the  insurer.    The  Health  Care  Benefit  Payment  shall  be  equal  to  the
amount  that  the  Company  would  have  otherwise  paid  for  COBRA  Premiums  (which  amount  shall  be  calculated  based  on  the
premium for the first month of COBRA coverage), and shall be paid until the earlier of: (i) the date the Benefits Payment Period
expires or (ii) the date upon which Executive obtains coverage under a medical plan by a subsequent employer.

(c)

In addition to the Change in Control Accelerated Vesting (if applicable), as defined in that certain
Employment Terms letter agreement between Executive and the Company dated June 2, 2019, as amended by that certain First
Amendment to Employment Terms Agreement on May 6, 2020 (collectively, Executive’s “Employment Terms”), in the case of a
Separation  from  Service  within  twelve  (12)  months  after  the  effective  date  of  a  Change  in  Control  (as  defined  below),  the
Company shall accelerate the vesting of each of Executive’s then-outstanding unvested equity compensation awards, or, in the
case  of  any  other  Separation  from  Service,  the  Company  shall  accelerate  the  vesting  of  each  of  Executive’s  then-outstanding
unvested  equity  compensation  awards  as  to  the  number  of  then-unvested  shares  subject  to  each  such  award  that  would  have
become vested, in the ordinary course, within the first twenty-four (24) months following Executive’s Separation from Service, in
either case effective immediately prior to such Separation from Service.  

Limitations and Conditions on Separation Benefits

3.

2.

 
 
 
(a)

Release Prior to Payment of Benefits. Prior to the payment or provision of
any of the Separation Benefits, Executive shall execute, and allow to become effective, the Release not later than sixty (60) days
following Executive’s Separation from Service.  Such Release shall specifically relate to all of Executive’s rights and claims in
existence at the time of such execution and shall confirm Executive’s continuing obligations to the Company (including but not
limited to obligations under any confidentiality and/or non-solicitation agreement with the Company).  No Separation Benefits
will be paid prior to the Release Date.

(b)

Income  and  Employment  Taxes.    Executive  agrees  that  Executive  shall  be  responsible  for  any
applicable  taxes  of  any  nature  (including  any  penalties  or  interest  that  may  apply  to  such  taxes)  that  the  Company  reasonably
determines apply to any payment made hereunder, that Executive’s receipt of any benefit hereunder is conditioned on Executive’s
satisfaction  of  any  applicable  withholding  or  similar  obligations  that  apply  to  such  benefit,  and  that  any  cash  payment  owed
hereunder will be reduced to satisfy any such withholding or similar obligations that may apply.

(c)

Compliance with Section 409A.  It is intended that each installment of the payments and benefits
provided for in this Agreement is a separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i).  For the
avoidance of doubt, it is intended that Separation Benefits set forth in this Agreement satisfy, to the greatest extent possible, the
exemptions  from,  or  comply  with,  the  application  of  Section  409A  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the
“Code”) and Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9) (together, with any state law of similar
effect, “Section 409A”). However, if the Company (or, if applicable, the successor entity thereto) determines that the Separation
Benefits provided under this Agreement constitute “deferred compensation” under Section 409A and Executive is, on the date of
his  or  her  Separation  from  Service,  a  “specified  employee”  of  the  Company  or  any  successor  entity  thereto,  as  such  term  is
defined  in  Section  409A(a)(2)(B)(i)  of  the  Code  (a  “Specified  Employee”),  then,  solely  to  the  extent  necessary  to  avoid  the
incurrence of the adverse personal tax consequences under Section 409A, the timing of the Separation Benefits described herein,
as applicable, shall be delayed as follows: on the earlier to occur of (i) the date that is six (6) months and one (1) business day
after Executive’s Separation from Service, (ii) the date of Executive’s death, or (iii) such earlier date as permitted under Section
409A  without  the  imposition  of  adverse  taxation  (such  earlier  date,  the  “Delayed  Initial  Payment  Date”).  Upon  the  Delayed
Initial  Payment  Date,  the  Company  (or  the  successor  entity  thereto,  as  applicable)  shall  pay  to  Executive  a  lump  sum  amount
equal  to  the  applicable  benefit  that  Executive  would  otherwise  have  received  through  the  Delayed  Initial  Payment  Date  if  the
commencement of the payment of the benefit had not been so delayed pursuant to this Section 3(c), and any remaining payments
due shall be paid as otherwise provided herein. No interest shall be due on any amounts so deferred. If the Separation Benefits are
not  covered  by  one  or  more  exemptions  from  the  application  of  Section  409A  and  the  Release  could  become  effective  in  the
calendar  year  following  the  calendar  year  in  which  Executive  has  a  Separation  from  Service,  the  Release  will  not  be  deemed
effective any earlier than the Release Date. To the extent that any provision of this Agreement is ambiguous as to its exemption or
compliance  with  Section  409A,  the  provision  will  be  read  in  such  a  manner  so  that  all  payments  hereunder  are  exempt  from
Section 409A to the maximum permissible extent. To the extent any payment under this Agreement may be classified as a “short-
term  deferral”  within  the  meaning  of  Section  409A,  such  payment  shall  be  deemed  a  short-term  deferral,  even  if  it  may  also
qualify for an exemption from Section 409A under another

3.

 
 
 
provision of Section 409A. With respect to reimbursements or in-kind benefits provided to Executive hereunder (or otherwise)
that are not exempt from Section 409A, the following rules shall apply: (i) the amount of expenses eligible for reimbursement, or
in-kind benefits provided, during any one of Executive’s taxable years shall not affect the expenses eligible for reimbursement, or
in-kind  benefit  to  be  provided  in  any  other  taxable  year,  (ii)  in  the  case  of  any  reimbursements  of  eligible  expenses,
reimbursement  shall  be  made  on  or  before  the  last  day  of  Executive’s  taxable  year  following  the  taxable  year  in  which  the
expense was incurred, and (iii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for
another benefit.

(d)

Related Matters.  Executive further acknowledges and agrees that as a condition to receipt of any
Separation  Benefits  (i)  Executive  must  comply  with  Executive’s  obligations  under  Executive’s  Employee  Confidential
Information  and  Invention  Assignment  Agreement;  and  (ii)  resign  from  all  Company  and  or  affiliate  positions,  including
membership on any Board (unless otherwise requested by the Company).

(e)

Successors.  Any successor to the Company (whether direct or indirect and whether by purchase,
lease,  merger,  consolidation,  liquidation  or  otherwise)  to  all  or  substantially  all  of  the  Company’s  business  and/or  assets  shall
assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same
manner  and  to  the  same  extent  as  the  Company  would  be  required  to  perform  such  obligations  in  the  absence  of  a
succession.  The terms of this Agreement and all of Executive’s rights hereunder and thereunder shall inure to the benefit of, and
be  enforceable  by,  Executive’s  personal  or  legal  representatives,  executors,  administrators,  successors,  heirs,  distributees,
devisees and legatees.

(f)

Notice.  Notices and all other communications contemplated by this Agreement shall be in writing
and  shall  be  deemed  to  have  been  duly  given  when  personally  delivered  or  when  mailed  by  U.S.  registered  or  certified  mail,
return receipt requested and postage prepaid.  Mailed notices to Executive shall be addressed to Executive at the home address
which Executive most recently communicated to the Company in writing.  In the case of the Company, mailed notices shall be
addressed to its corporate headquarters, and all notices shall be directed to the attention of its Board Chair.

4.

Definitions.

(a)

Cause.  For purposes of this Agreement, “Cause”, as determined by the Board acting in good faith
and  based  on  information  then  known  to  it,  shall  mean  the  occurrence  of  one  or  more  of  the  following:  (i)  Executive’s  gross
negligence or knowing and willful action which is or is likely to be materially injurious to the Company; (ii) any intentional act
by  Executive  in  connection  with  his  responsibilities  as  an  employee  constituting  fraud  or  a  felony  crime;  (iii)  Executive’s
consistent  failure  to  report  for  work  or  perform  his  duties  as  directed  by  the  Company’s  Board  of  Directors;  (iv)  persistent  or
repeated  material  breach  of  this  Agreement  or  any  agreement  between  Executive  and  the  Company;  (v)  Executive  becoming
disqualified from holding office through his own act or omission; (vi) an unauthorized use or disclosure by the Executive of the
Company’s  confidential  information  or  trade  secrets,  which  use  or  disclosure  causes  material  harm  to  the  Company;  or  (vii)  a
material failure by the Executive to comply with the Company’s written policies or rules which is or is likely to be materially
injurious to the

4.

 
 
 
Company; provided, however, that in any such event, there has been delivered to Executive a written demand for performance
from the Board which describes the basis for the Board’s belief that Executive has committed one of the acts set forth in clauses
(i)-(vii) above and provides Executive with thirty (30) days to take corrective action (which may include any suspension period).

consummation of a transaction or series of transactions that results in any of the following:

(b)

Change  in  Control.    For  purposes  of  this  Agreement,  “Change  in  Control”  means  the

(i)

a  merger,  consolidation  or  similar  corporate  transaction  involving
(directly  or  indirectly)  the  Company  and,  immediately  following  which  the  stockholders  of  the  Company  immediately  prior
thereto  do  not  own,  directly  or  indirectly,  outstanding  voting  securities  representing  more  than  fifty  percent  (50%)  of  the
combined outstanding voting power of the surviving entity in such merger, consolidation or similar corporate transaction or more
than  fifty  percent  (50%)  of  the  combined  outstanding  voting  power  of  the  parent  of  the  surviving  entity  in  such  merger,
consolidation or similar corporate transaction; or

consolidated assets of the Company that occurs over a period of not more than twelve (12) months.

(ii)

a  sale  or  other  disposition  of  all  or  substantially  all  of  the

However, a Change in Control will not include (1) any consolidation or merger effected exclusively to change the domicile of the
Company,  or  (2)  any  transaction  or  series  of  transactions  principally  for  bona  fide  equity  financing  purposes  in  which  cash  is
received  by  the  Company  or  any  successor  or  indebtedness  of  the  Company  is  cancelled  or  converted  or  a  combination
thereof.    In  addition,  no  transaction  will  be  a  Change  in  Control  unless  it  is  also  “change  in  ownership  of  a  corporation”  or
“change  in  ownership  of  a  substantial  portion  of  a  corporation’s  assets”  as  defined  under  in  Treasury  Regulations  Sections
1.409A-3(i)(5)(v) and (vii) without regard to any alternative definitions thereunder.

(c)

Good Reason. For purposes of this Agreement, “Good Reason” for Executive’s resignation of his
or her employment will exist following the occurrence of any of the following without Executive’s written consent: (i) a material
reduction in Executive’s base salary, which the parties agree is a reduction of at least ten percent (10%) of Executive’s base salary
(provided,  however,  that  such  reduction  will  not  be  considered  Good  Reason  if  made  in  connection  with  an  across-the-board
salary reduction affecting all members of management); (ii) a requirement that Executive report to a corporate officer rather than
directly to the Board, or a material reduction in Executive’s duties, responsibilities and/or authority, provided, however, that the
acquisition  of  the  Company  in  a  Change  in  Control  and  subsequent  conversion  of  the  Company  to  a  division  or  unit  of  the
acquiring company will not by itself result in any such “material reduction”; (iii) a relocation of Executive’s principal place of
employment to a place that increases Executive’s one-way commute by more than fifty (50) miles as compared to Executive’s
then-current principal place of employment immediately prior to such relocation; or (iv) a material breach by the Company of
this Agreement.  In order to resign for Good Reason, Executive must provide written notice to the Board within thirty (30) days
after the first occurrence of the event giving rise to Good Reason setting forth the basis for Executive’s resignation, allow the
Company at least thirty (30) days from receipt of such written notice to cure such event, and if such event is

5.

 
 
 
not reasonably cured within such period, Executive must resign from all positions Executive then holds with the Company not
later than thirty (30) days after the expiration of the cure period or the date of notification to Executive that the Company will not
so cure. Executive understands and agrees that the requirement for Executive’s performance of services within twenty (20) miles
of Palo Alto, California does not give rise to Good Reason.

5.

Parachute Payments.

(a)

If  any  payment  or  benefit  (including  payments  and  benefits  pursuant  to  this  Agreement)  that
Executive  would  receive  in  connection  with  a  Change  in  Control  from  the  Company  or  otherwise  (“Transaction  Payment”)
would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be
subject  to  the  excise  tax  imposed  by  Section  4999  of  the  Code  (the  “Excise  Tax”),  then  the  Company  shall  cause  to  be
determined, before any amounts of the Transaction Payment are paid to Executive, which of the following two alternative forms
of  payment  would  result  in  Executive’s  receipt,  on  an  after-tax  basis,  of  the  greater  amount  of  the  Transaction  Payment
notwithstanding that all or some portion of the Transaction Payment may be subject to the Excise Tax: (1) payment in full of the
entire amount of the Transaction Payment (a “Full Payment”), or (2) payment of only a part of the Transaction Payment so that
Executive receives the largest payment possible without the imposition of the Excise Tax (a “Reduced Payment”).  For purposes
of determining whether to make a Full Payment or a Reduced Payment, the Company shall cause to be taken into account all
applicable  federal,  state  and  local  income  and  employment  taxes  and  the  Excise  Tax  (all  computed  at  the  highest  applicable
marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and
local  taxes).    If  a  Reduced  Payment  is  made,  (x)  Executive  shall  have  no  rights  to  any  additional  payments  and/or  benefits
constituting the Transaction Payment, and (y) reduction in payments and/or benefits shall occur in the manner that results in the
greatest economic benefit to Executive as determined in this paragraph (the “Reduction Method”).  If more than one method of
reduction will result in the same economic benefit, the portions of the Transaction Payment shall be reduced pro rata (the “Pro
Rata Reduction Method”).

(b)

Notwithstanding any provision of subsection (a) above to the contrary, if the Reduction Method or
the Pro Rata Reduction Method would result in any portion of the Transaction Payment being subject to taxes pursuant to Section
409A  that  would  not  otherwise  be  subject  to  taxes  pursuant  to  Section  409A,  then  the  Reduction  Method  and/or  the  Pro  Rata
Reduction  Method,  as  the  case  may  be,  shall  be  modified  so  as  to  avoid  the  imposition  of  taxes  pursuant  to  Section  409A  as
follows:  (i) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for
Executive as determined on an after-tax basis; (ii) as a second priority, Transaction Payments that are contingent on future events
(e.g., being terminated without Cause), shall be reduced (or eliminated) before Transaction Payments that are not contingent on
future events; and (iii) as a third priority, Transaction Payments that are "deferred compensation" within the meaning of Section
409A shall be reduced (or eliminated) before Transaction Payments that are not deferred compensation within the meaning of
Section 409A.

shall make all determinations required to be made under this Section 5.  If the professional firm so engaged by the Company is
serving as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a
nationally  recognized  independent  registered  public  accounting  firm  to  make  the  determinations  required  hereunder.    The
Company shall bear all expenses with respect to the determinations by such professional firm required to be made hereunder.

(d)

The professional firm engaged to make the determinations hereunder shall provide its calculations,
together with detailed supporting documentation, to the Company and Executive within fifteen (15) calendar days after the date
on which Executive’s right to a Transaction Payment is triggered or such other time as reasonably requested by the Company or
Executive.    If  the  professional  firm  determines  that  no  Excise  Tax  is  payable  with  respect  to  the  Transaction  Payment,  either
before  or  after  the  application  of  the  Reduced  Amount,  it  shall  furnish  the  Company  and  Executive  with  detailed  supporting
calculations of its determinations that no Excise Tax will be imposed with respect to such Transaction Payment.  Any good faith
determinations of the professional firm made hereunder shall be final, binding and conclusive upon the Company and Executive.

6.

Other  Employment  Terms  and  Conditions.    The  employment  relationship  between  the  parties  shall  be
governed  by  the  general  employment  policies  and  procedures  of  the  Company,  including  those  relating  to  the  protection  of
confidential information and assignment of inventions; provided, however, that when the terms of this Agreement differ from or
are in conflict with the Company’s general employment policies or procedures, this Agreement shall control.

7.

Dispute Resolution.  

(a)

Executive  and  the  Company  agree  that  any  and  all  disputes,  claims,  or  causes  of  action,  in  law  or  equity,
including but not limited to statutory claims, arising from or relating to the enforcement, breach, performance, or interpretation of
this  Agreement,  Executive’s  employment  with  the  Company,  or  the  termination  of  Executive’s  employment,  shall  be  resolved
pursuant to the Federal Arbitration Act, 9 U.S.C. § 1-16 (“FAA”), to the fullest extent permitted by law, by final, binding and
confidential arbitration conducted by JAMS or its successor, under JAMS’ then applicable rules and procedures for employment
disputes  before  a  single  arbitrator  (available  upon  request  and  also  currently  available  at  http://www.jamsadr.com/rules-
employment-arbitration/),  in  San  Jose,  California.  Executive  acknowledges  that  by  agreeing  to  this  arbitration  procedure,
both  Executive  and  the  Company  waive  the  right  to  resolve  any  such  dispute  through  a  trial  by  jury  or  judge  or
administrative proceeding.  

(b)

All  claims,  disputes,  or  causes  of  action  under  this  arbitration  agreement,  whether  by  Executive  or  the
Company, must be brought in an individual capacity, and shall not be brought as a plaintiff (or claimant) or class member in any
purported  class  or  representative  proceeding,  nor  joined  or  consolidated  with  the  claims  of  any  other  person  or  entity.    The
arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative
or  class  proceeding.    To  the  extent  that  the  preceding  sentences  regarding  class  claims  or  proceedings  are  found  to  violate
applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class shall proceed in a court
of law rather than by arbitration.  

7.

 
 
 
(c)

This  arbitration  agreement  shall  not  apply  to  any  action  or  claim  that  cannot  be  subject  to  mandatory
arbitration as a matter of law, including, without limitation, sexual assault disputes and sexual harassment disputes as defined in
the  FAA,  claims  brought  pursuant  to  the  California  Private  Attorneys  General  Act  of  2004,  as  amended,  the  California  Fair
Employment  and  Housing  Act,  as  amended,  and  the  California  Labor  Code,  as  amended,  to  the  extent  such  claims  are  not
permitted  by  applicable  law(s)  to  be  submitted  to  mandatory  arbitration  and  the  applicable  law(s)  are  not  preempted  by  the
Federal  Arbitration  Act  or  otherwise  invalid  (collectively,  the  “Excluded  Claims”).    In  the  event  Executive  intends  to  bring
multiple claims, including one of the Excluded Claims listed above, the Excluded Claims may be filed with a court, while any
other claims will remain subject to mandatory arbitration.  Executive will have the right to be represented by legal counsel at any
arbitration proceeding.  

(d)

Questions  of  whether  a  claim  is  subject  to  arbitration  under  this  agreement  shall  be  decided  by  the
arbitrator.  Likewise, procedural questions which grow out of the dispute and bear on the final disposition are also matters for the
arbitrator.  The arbitrator shall: (i) have the authority to compel adequate discovery for the resolution of the dispute and to award
such  relief  as  would  otherwise  be  permitted  by  law;  and  (ii)  issue  a  written  statement  signed  by  the  arbitrator  regarding  the
disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential
findings and conclusions on which the award is based.  The arbitrator shall be authorized to award all relief that Executive or the
Company  would  be  entitled  to  seek  in  a  court  of  law.    The  Company  shall  pay  all  JAMS  arbitration  fees  in  excess  of  the
administrative  fees  that  Executive  would  be  required  to  pay  if  the  dispute  were  decided  in  a  court  of  law.    Nothing  in  this
arbitration agreement is intended to prevent either Executive or the Company from obtaining injunctive relief in court to prevent
irreparable harm pending the conclusion of any such arbitration.  Any awards or orders in such arbitrations may be entered and
enforced as judgments in the federal and state courts of any competent jurisdiction.

8.

Miscellaneous Provisions.

No  Duty  to  Mitigate.    Executive  shall  not  be  required  to  mitigate  the  amount  of  any  payment
contemplated by this Agreement (whether by seeking new employment or in any other manner), nor shall any such payment be
reduced by any earnings that Executive may receive from any other source.

(a)

(b)

Waiver.    No  provision  of  this  Agreement  shall  be  modified,  waived  or  discharged  unless  the
modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company
(other than Executive).  No waiver by either party of any breach of, or of compliance with, any condition or provision of this
Agreement  by  the  other  party  shall  be  considered  a  waiver  of  any  other  condition  or  provision  or  of  the  same  condition  or
provision at another time.

(c)

Whole  Agreement.    No  agreements,  representations  or  understandings  (whether  oral  or  written
and whether express or implied) which are not expressly set forth in this Agreement have been made or entered into by either
party with respect to the subject matter hereof.  This Agreement supersedes any agreement (or portion thereof) concerning similar
subject  matter  dated  prior  to  the  date  of  this  Agreement,  and  by  execution  of  this  Agreement  both  parties  agree  that  any  such
predecessor agreement (or portion thereof) shall be deemed null and void.  For the

8.

 
 
 
avoidance  of  doubt,  the  parties  agree  that  this  Agreement  does  not  supersede:  (i)  the  provisions  of  Executive’s  Employment
Terms that do not address termination or severance benefits, including without limitation the provision pertaining to Change in
Control Accelerated Vesting, or (ii) Executive’s Employee Confidential Information and Invention Assignment Agreement with
the Company.

Choice of Law.  The validity, interpretation, construction and performance of this Agreement shall
be governed by the laws of the State of California without reference to conflict of laws provisions, and the parties hereto submit
to the exclusive jurisdiction of the state and federal courts of the State of California.

(d)

(e)

Severability.    If  any  term  or  provision  of  this  Agreement  or  the  application  thereof  to  any
circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective
as  to  such  jurisdiction  to  the  extent  of  such  invalidity  or  unenforceability  without  invalidating  or  rendering  unenforceable  the
remaining terms and provisions of this Agreement or the application of such terms and provisions to circumstances other than
those as to which it is held invalid or unenforceable, and a suitable and equitable term or provision shall be substituted therefor to
carry out, insofar as may be valid and enforceable, the intent and purpose of the invalid or unenforceable term or provision.

PERSONALIS, INC.

FIRST AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

(SENIOR VICE PRESIDENT, VICE PRESIDENT, OR EQUIVALENT INDIVIDUAL CONTRIBUTOR)

This  First  Amended  and  Restated  Executive  Severance  Agreement  (the  “Agreement”),  effective  as  of  February  23,
2022, amends, supersedes and restates in its entirety that certain Executive Severance Agreement by and between Dr. Richard
Chen (“Executive”) and Personalis, Inc. (the “Company”) dated June 2, 2019.  This Agreement is intended to provide Executive
with certain benefits described herein upon the occurrence of specific events.  

RECITALS

A.

The Company’s Board of Directors (the “Board”) believes it is in the best interests of the Company and its

shareholders to retain Executive and provide incentives to Executive to continue in the service of the Company.

B.

The Board further believes that it is imperative to provide Executive with certain benefits upon termination of
Executive’s  employment,  which  benefits  are  intended  to  provide  Executive  with  financial  security  and  sufficient  income  and
encouragement to Executive to remain with the Company.

C.

To  accomplish  the  foregoing  objectives,  the  Board  has  directed  the  Company,  upon  execution  of  this

Agreement by Executive, to agree to the terms provided in this Agreement.

Now  therefore,  in  consideration  of  the  mutual  promises,  covenants  and  agreements  contained  herein,  the

parties hereto agree as follows:

1.

At-Will  Employment.    Executive’s  employment  is  at-will,  which  means  that  the  Company  may  terminate
Executive’s  employment  at  any  time,  with  or  without  Cause  or  advance  notice.    Similarly,  Executive  may  resign  Executive’s
employment  at  any  time,  with  or  without  advance  notice,  and  with  or  without  Good  Reason.    Executive  shall  not  receive  any
compensation  of  any  kind,  including,  without  limitation,  equity  award  vesting  acceleration  and  severance  benefits,  following
Executive’s last day of employment with the Company, except as expressly provided herein.

2.

Benefits Upon Termination of Employment.

(a)

Termination in Connection with or Following a Change in Control.  If Executive’s employment
is terminated without Cause (as defined below) (and other than as a result of Executive’s death or disability), or Executive resigns
for Good Reason (as defined below), in either case within twelve (12) months after the effective date of a Change in Control (as
defined below), and provided such termination constitutes a “separation from service” (within the meaning

1.

 
 
 
 
 
 
of Treasury Regulation Section 1.409A-1(h), such termination a “Separation from Service”), and provided further that Executive
signs and allows to become effective a general release of all claims in favor of the Company in a form provided by the Company
(the “Release”), within sixty (60) days after Executive’s Separation from Service (the date that the Release becomes effective and
may no longer be revoked by Executive is referred to as the “Release Date”), then the Company shall provide Executive with the
following severance benefits (the “Change in Control Separation Benefits”):

The Company shall pay Executive cash severance in an amount equal to nine (9) months
of  Executive’s  then-current  base  salary,  ignoring  any  decrease  in  base  salary  that  forms  the  basis  for  Good  Reason,  less  all
applicable withholdings and deductions, paid on the Company’s first regular payroll date following the Release Date.  

(i)

(ii)

Should  Executive  timely  elect  to  continue  Executive’s  medical,  dental  and/or  vision
insurance  benefits  pursuant  to  the  Consolidated  Omnibus  Budget  Reconciliation  Act  of  1985  (“COBRA”)  or  any  analogous
provisions of applicable state law, the Company shall pay Executive’s COBRA premiums for Executive and Executive’s eligible
dependents (“COBRA Premiums”) for a period of nine (9) months following Executive’s Separation from Service (the “Change
in Control Benefits Payment Period”) or, if earlier, the date upon which Executive obtains coverage under a medical plan by a
subsequent employer.  The Company’s obligation to pay any COBRA Premiums will be subject to the then-current requirements
of COBRA and any other laws affecting the payment of COBRA premiums by the Company.  Notwithstanding the foregoing, if
the  Company  determines,  in  its  sole  discretion,  that  the  Company  cannot  provide  the  COBRA  Premiums  without  potentially
incurring  financial  costs  or  penalties  under  applicable  law,  the  Company  shall  in  lieu  thereof  pay  Executive  a  taxable  cash
amount,  which  payment  shall  be  made  regardless  of  whether  Executive  elects  health  care  continuation  coverage  (the  “Health
Care Benefit Payment”).  The Health Care Benefit Payment shall be paid in monthly installments on the same schedule that the
COBRA  Premiums  would  otherwise  have  been  paid  to  the  insurer.    The  Health  Care  Benefit  Payment  shall  be  equal  to  the
amount  that  the  Company  would  have  otherwise  paid  for  COBRA  Premiums  (which  amount  shall  be  calculated  based  on  the
premium  for  the  first  month  of  COBRA  coverage),  and  shall  be  paid  until  the  earlier  of:  (i)  the  date  the  Change  in  Control
Benefits Payment Period expires or (ii) the date upon which Executive obtains coverage under a medical plan by a subsequent
employer.

unvested equity compensation awards, effective immediately prior to such Separation from Service.  

(iii)

The  Company  shall  accelerate  the  vesting  of  each  of  Executive’s  then-outstanding

(b)

Termination  Not  in  Connection  with  or  Following  a  Change  in  Control.    If  Executive’s
employment is terminated without Cause (and other than as a result of Executive’s death or disability), or Executive resigns for
Good  Reason,  in  either  case  at  any  time  that  is  not  within  twelve  (12)  months  after  a  Change  in  Control,  and  provided  such
termination  constitutes  a  Separation  from  Service,  and  provided  Executive  signs  and  allows  to  become  effective  the  Release
within sixty (60) days after Executive’s Separation from Service, then the Company shall provide Executive with the following
severance benefits (collectively with the Change in Control Separation Benefits, the “Separation Benefits”):

2.

 
 
 
The Company shall pay Executive cash severance in an amount equal to six (6) months of
Executive’s then current base salary, less all applicable withholdings and deductions, paid in a lump sum on the Company’s first
regular payroll date after the Release Date.

(i)

(ii)

Should  Executive  timely  elect  to  continue  Executive’s  medical,  dental  and/or  vision
insurance benefits pursuant to COBRA, the Company shall pay the COBRA Premiums for a period of six (6) months following
the  effective  date  of  Executive’s  Separation  from  Service  (the  “Benefits Payment Period”)  or,  if  earlier,  the  date  upon  which
Executive  obtains  coverage  under  a  medical  plan  by  a  subsequent  employer.    The  Company’s  obligation  to  pay  any  COBRA
Premiums  will  be  subject  to  the  then-current  requirements  of  COBRA  and  any  other  laws  affecting  the  payment  of  COBRA
premiums  by  the  Company.    Notwithstanding  the  foregoing,  if  the  Company  determines,  in  its  sole  discretion,  that  it  cannot
provide the COBRA Premiums without potentially incurring financial costs or penalties under applicable law, the Company shall
in lieu thereof pay Executive the Health Care Benefit Payment in monthly installments on the same schedule that the COBRA
Premiums  would  otherwise  have  been  paid  to  the  insurer,  which  shall  be  paid  until  the  earlier  of:  (i)  the  date  the  Benefits
Payment Period expires or (ii) the date upon which Executive obtains coverage under a medical plan by a subsequent employer.

3.

Limitations and Conditions on Separation Benefits

(a)

Release Prior to Payment of Benefits. Prior to the payment or provision of
any of the Separation Benefits, Executive shall execute, and allow to become effective, the Release not later than sixty (60) days
following Executive’s Separation from Service.  Such Release shall specifically relate to all of Executive’s rights and claims in
existence at the time of such execution and shall confirm Executive’s continuing obligations to the Company (including but not
limited to obligations under any confidentiality and/or non-solicitation agreement with the Company).  No Separation Benefits
will be paid prior to the Release Date.

(b)

Income  and  Employment  Taxes.    Executive  agrees  that  Executive  shall  be  responsible  for  any
applicable  taxes  of  any  nature  (including  any  penalties  or  interest  that  may  apply  to  such  taxes)  that  the  Company  reasonably
determines apply to any payment made hereunder, that Executive’s receipt of any benefit hereunder is conditioned on Executive’s
satisfaction  of  any  applicable  withholding  or  similar  obligations  that  apply  to  such  benefit,  and  that  any  cash  payment  owed
hereunder will be reduced to satisfy any such withholding or similar obligations that may apply.

(c)

Compliance with Section 409A.  It is intended that each installment of the payments and benefits
provided for in this Agreement is a separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i).  For the
avoidance of doubt, it is intended that Separation Benefits set forth in this Agreement satisfy, to the greatest extent possible, the
exemptions  from,  or  comply  with,  the  application  of  Section  409A  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the
“Code”) and Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9) (together, with any state law of similar
effect, “Section 409A”). However, if the Company (or, if applicable, the successor entity thereto) determines that the Separation
Benefits provided under this Agreement constitute “deferred compensation” under Section 409A and Executive is, on the date of
his or her Separation from Service, a “specified employee” of the

3.

 
 
 
Company  or  any  successor  entity  thereto,  as  such  term  is  defined  in  Section  409A(a)(2)(B)(i)  of  the  Code  (a  “Specified
Employee”), then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section
409A, the timing of the Separation Benefits described herein, as applicable, shall be delayed as follows: on the earlier to occur of
(i) the date that is six (6) months and one (1) business day after Executive’s Separation from Service, (ii) the date of Executive’s
death, or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation (such earlier date, the
“Delayed  Initial  Payment  Date”).  Upon  the  Delayed  Initial  Payment  Date,  the  Company  (or  the  successor  entity  thereto,  as
applicable)  shall  pay  to  Executive  a  lump  sum  amount  equal  to  the  applicable  benefit  that  Executive  would  otherwise  have
received through the Delayed Initial Payment Date if the commencement of the payment of the benefit had not been so delayed
pursuant to this Section 3(c), and any remaining payments due shall be paid as otherwise provided herein. No interest shall be
due on any amounts so deferred. If the Separation Benefits are not covered by one or more exemptions from the application of
Section 409A and the Release could become effective in the calendar year following the calendar year in which Executive has a
Separation  from  Service,  the  Release  will  not  be  deemed  effective  any  earlier  than  the  Release  Date.  To  the  extent  that  any
provision of this Agreement is ambiguous as to its exemption or compliance with Section 409A, the provision will be read in
such a manner so that all payments hereunder are exempt from Section 409A to the maximum permissible extent. To the extent
any  payment  under  this  Agreement  may  be  classified  as  a  “short-term  deferral”  within  the  meaning  of  Section  409A,  such
payment shall be deemed a short-term deferral, even if it may also qualify for an exemption from Section 409A under another
provision of Section 409A. With respect to reimbursements or in-kind benefits provided to Executive hereunder (or otherwise)
that are not exempt from Section 409A, the following rules shall apply: (i) the amount of expenses eligible for reimbursement, or
in-kind benefits provided, during any one of Executive’s taxable years shall not affect the expenses eligible for reimbursement, or
in-kind  benefit  to  be  provided  in  any  other  taxable  year,  (ii)  in  the  case  of  any  reimbursements  of  eligible  expenses,
reimbursement  shall  be  made  on  or  before  the  last  day  of  Executive’s  taxable  year  following  the  taxable  year  in  which  the
expense was incurred, and (iii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for
another benefit.

(d)

Related Matters.  Executive further acknowledges and agrees that as a condition to receipt of any
Separation  Benefits  (i)  Executive  must  comply  with  Executive’s  obligations  under  Executive’s  Employee  Confidential
Information  and  Invention  Assignment  Agreement;  and  (ii)  resign  from  all  Company  and  or  affiliate  positions,  including
membership on any Board (unless otherwise requested by the Company).

(e)

Successors.  Any successor to the Company (whether direct or indirect and whether by purchase,
lease,  merger,  consolidation,  liquidation  or  otherwise)  to  all  or  substantially  all  of  the  Company’s  business  and/or  assets  shall
assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same
manner  and  to  the  same  extent  as  the  Company  would  be  required  to  perform  such  obligations  in  the  absence  of  a
succession.  The terms of this Agreement and all of Executive’s rights hereunder and thereunder shall inure to the benefit of, and
be  enforceable  by,  Executive’s  personal  or  legal  representatives,  executors,  administrators,  successors,  heirs,  distributees,
devisees and legatees.

4.

 
 
 
(f)

Notice.  Notices and all other communications contemplated by this Agreement shall be in writing
and  shall  be  deemed  to  have  been  duly  given  when  personally  delivered  or  when  mailed  by  U.S.  registered  or  certified  mail,
return receipt requested and postage prepaid.  Mailed notices to Executive shall be addressed to Executive at the home address
which Executive most recently communicated to the Company in writing.  In the case of the Company, mailed notices shall be
addressed to its corporate headquarters, and all notices shall be directed to the attention of its Chief Executive Officer.

or her employment will exist following the occurrence of any of the following without Executive’s written consent: (i) a material
reduction in Executive’s base salary, which the parties agree is a reduction of at least ten percent (10%) of Executive’s base salary
(provided,  however,  that  such  reduction  will  not  be  considered  Good  Reason  if  made  in  connection  with  an  across-the-board
salary  reduction  affecting  all  members  of  management);  (ii)  a  material  reduction  in  Executive’s  duties,  responsibilities  and/or
authority, provided, however, that a change in job position (including a change in title) after or in connection with a Change in
Control  shall  not  be  deemed  a  “material  reduction”  in  and  of  itself  unless  Executive’s new duties are materially reduced from
Executive’s prior duties; (iii) a relocation of Executive’s principal place of employment to a place that increases Executive’s one-
way commute by more than fifty (50) miles as compared to Executive’s then-current principal place of employment immediately
prior  to  such  relocation;  or  (iv)  a  material  breach  by  the  Company  of  this  Agreement.    In  order  to  resign  for  Good  Reason,
Executive must provide written notice to the Board within thirty (30) days after the first occurrence of the event giving rise to
Good Reason setting forth the basis for Executive’s resignation, allow the Company at least thirty (30) days from receipt of such
written notice to cure such event, and if such event is not reasonably cured within such period, Executive must resign from all
positions Executive then holds with the Company not later than thirty (30) days after the expiration of the cure period or the date
of  notification  to  Executive  that  the  Company  will  not  so  cure.    Executive  understands  and  agrees  that  the  requirement  for
Executive’s performance of services within twenty (20) miles of Palo Alto, California does not give rise to Good Reason.

Parachute Payments.

(a)

If  any  payment  or  benefit  (including  payments  and  benefits  pursuant  to  this  Agreement)  that
Executive  would  receive  in  connection  with  a  Change  in  Control  from  the  Company  or  otherwise  (“Transaction  Payment”)
would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be
subject  to  the  excise  tax  imposed  by  Section  4999  of  the  Code  (the  “Excise  Tax”),  then  the  Company  shall  cause  to  be
determined, before any amounts of the Transaction Payment are paid to Executive, which of the following two alternative forms
of  payment  would  result  in  Executive’s  receipt,  on  an  after-tax  basis,  of  the  greater  amount  of  the  Transaction  Payment
notwithstanding that all or some portion of the Transaction Payment may be subject to the Excise Tax: (1) payment in full of the
entire amount of the Transaction Payment (a “Full Payment”), or (2) payment of only a part of the Transaction Payment so that
Executive receives the largest payment possible without the imposition of the Excise Tax (a “Reduced Payment”).  For purposes
of determining whether to make a Full Payment or a Reduced Payment, the Company shall cause to be taken into account all
applicable  federal,  state  and  local  income  and  employment  taxes  and  the  Excise  Tax  (all  computed  at  the  highest  applicable
marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and
local  taxes).    If  a  Reduced  Payment  is  made,  (x)  Executive  shall  have  no  rights  to  any  additional  payments  and/or  benefits
constituting the Transaction Payment, and (y) reduction in payments and/or benefits shall occur in the manner that results in the
greatest economic benefit to Executive as determined in this paragraph (the “Reduction Method”).  If more than one method of
reduction will result in the same economic benefit, the portions of the Transaction Payment shall be reduced pro rata (the “Pro
Rata Reduction Method”).

6.

 
 
 
(b)

Notwithstanding any provision of subsection (a) above to the contrary, if the Reduction Method or
the Pro Rata Reduction Method would result in any portion of the Transaction Payment being subject to taxes pursuant to Section
409A  that  would  not  otherwise  be  subject  to  taxes  pursuant  to  Section  409A,  then  the  Reduction  Method  and/or  the  Pro  Rata
Reduction  Method,  as  the  case  may  be,  shall  be  modified  so  as  to  avoid  the  imposition  of  taxes  pursuant  to  Section  409A  as
follows:  (i) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for
Executive as determined on an after-tax basis; (ii) as a second priority, Transaction Payments that are contingent on future events
(e.g., being terminated without Cause), shall be reduced (or eliminated) before Transaction Payments that are not contingent on
future events; and (iii) as a third priority, Transaction Payments that are "deferred compensation" within the meaning of Section
409A shall be reduced (or eliminated) before Transaction Payments  that  are  not  deferred  compensation  within  the  meaning  of
Section 409A.

(c)

The  professional  firm  engaged  by  the  Company  for  general  tax  purposes  or  the  Company’s
corporate law firm as of the day prior to the effective date of the Change in Control shall make all determinations required to be
made  under  this  Section  5.    If  the  professional  firm  so  engaged  by  the  Company  is  serving  as  accountant  or  auditor  for  the
individual,  entity  or  group  effecting  the  Change  in  Control,  the  Company  shall  appoint  a  nationally  recognized  independent
registered  public  accounting  firm  to  make  the  determinations  required  hereunder.    The  Company  shall  bear  all  expenses  with
respect to the determinations by such professional firm required to be made hereunder.

(d)

The professional firm engaged to make the determinations hereunder shall provide its calculations,
together with detailed supporting documentation, to the Company and Executive within fifteen (15) calendar days after the date
on which Executive’s right to a Transaction Payment is triggered or such other time as reasonably requested by the Company or
Executive.    If  the  professional  firm  determines  that  no  Excise  Tax  is  payable  with  respect  to  the  Transaction  Payment,  either
before  or  after  the  application  of  the  Reduced  Amount,  it  shall  furnish  the  Company  and  Executive  with  detailed  supporting
calculations of its determinations that no Excise Tax will be imposed with respect to such Transaction Payment.  Any good faith
determinations of the professional firm made hereunder shall be final, binding and conclusive upon the Company and Executive.

6.

Other  Employment  Terms  and  Conditions.    The  employment  relationship  between  the  parties  shall  be
governed  by  the  general  employment  policies  and  procedures  of  the  Company,  including  those  relating  to  the  protection  of
confidential information and assignment of inventions; provided, however, that when the terms of this Agreement differ from or
are in conflict with the Company’s general employment policies or procedures, this Agreement shall control.

7.

Dispute Resolution.  

(a)

Executive  and  the  Company  agree  that  any  and  all  disputes,  claims,  or  causes  of  action,  in  law  or  equity,
including but not limited to statutory claims, arising from or relating to the enforcement, breach, performance, or interpretation of
this  Agreement,  Executive’s  employment  with  the  Company,  or  the  termination  of  Executive’s  employment,  shall  be  resolved
pursuant to the Federal Arbitration Act, 9 U.S.C. § 1-16 (“FAA”), to the fullest extent permitted

7.

 
 
 
by law, by final, binding and confidential arbitration conducted by JAMS or its successor, under JAMS’ then applicable rules and
procedures  for  employment  disputes  before  a  single  arbitrator  (available  upon  request  and  also  currently  available  at
http://www.jamsadr.com/rules-employment-arbitration/), in San Jose, California. Executive acknowledges  that  by  agreeing  to
this arbitration procedure, both Executive and the Company waive the right to resolve any such dispute through a trial by
jury or judge or administrative proceeding.  

(b)

All  claims,  disputes,  or  causes  of  action  under  this  arbitration  agreement,  whether  by  Executive  or  the
Company, must be brought in an individual capacity, and shall not be brought as a plaintiff (or claimant) or class member in any
purported  class  or  representative  proceeding,  nor  joined  or  consolidated  with  the  claims  of  any  other  person  or  entity.    The
arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative
or  class  proceeding.    To  the  extent  that  the  preceding  sentences  regarding  class  claims  or  proceedings  are  found  to  violate
applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class shall proceed in a court
of law rather than by arbitration.  

(c)

This  arbitration  agreement  shall  not  apply  to  any  action  or  claim  that  cannot  be  subject  to  mandatory
arbitration as a matter of law, including, without limitation, sexual assault disputes and sexual harassment disputes as defined in
the  FAA,  claims  brought  pursuant  to  the  California  Private  Attorneys  General  Act  of  2004,  as  amended,  the  California  Fair
Employment  and  Housing  Act,  as  amended,  and  the  California  Labor  Code,  as  amended,  to  the  extent  such  claims  are  not
permitted  by  applicable  law(s)  to  be  submitted  to  mandatory  arbitration  and  the  applicable  law(s)  are  not  preempted  by  the
Federal  Arbitration  Act  or  otherwise  invalid  (collectively,  the  “Excluded  Claims”).    In  the  event  Executive  intends  to  bring
multiple claims, including one of the Excluded Claims listed above, the Excluded Claims may be filed with a court, while any
other claims will remain subject to mandatory arbitration.  Executive will have the right to be represented by legal counsel at any
arbitration proceeding.  

(d)

Questions  of  whether  a  claim  is  subject  to  arbitration  under  this  agreement  shall  be  decided  by  the
arbitrator.  Likewise, procedural questions which grow out of the dispute and bear on the final disposition are also matters for the
arbitrator.  The arbitrator shall: (i) have the authority to compel adequate discovery for the resolution of the dispute and to award
such  relief  as  would  otherwise  be  permitted  by  law;  and  (ii)  issue  a  written  statement  signed  by  the  arbitrator  regarding  the
disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential
findings and conclusions on which the award is based.  The arbitrator shall be authorized to award all relief that Executive or the
Company  would  be  entitled  to  seek  in  a  court  of  law.    The  Company  shall  pay  all  JAMS  arbitration  fees  in  excess  of  the
administrative  fees  that  Executive  would  be  required  to  pay  if  the  dispute  were  decided  in  a  court  of  law.    Nothing  in  this
arbitration agreement is intended to prevent either Executive or the Company from obtaining injunctive relief in court to prevent
irreparable harm pending the conclusion of any such arbitration.  Any awards or orders in such arbitrations may be entered and
enforced as judgments in the federal and state courts of any competent jurisdiction.

Miscellaneous Provisions.

8.

8.

 
 
 
No  Duty  to  Mitigate.    Executive  shall  not  be  required  to  mitigate  the  amount  of  any  payment
contemplated by this Agreement (whether by seeking new employment or in any other manner), nor shall any such payment be
reduced by any earnings that Executive may receive from any other source.

(a)

(b)

Waiver.    No  provision  of  this  Agreement  shall  be  modified,  waived  or  discharged  unless  the
modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company
(other than Executive).  No waiver by either party of any breach of, or of compliance with, any condition or provision of this
Agreement  by  the  other  party  shall  be  considered  a  waiver  of  any  other  condition  or  provision  or  of  the  same  condition  or
provision at another time.

(c)

Whole  Agreement.    No  agreements,  representations  or  understandings  (whether  oral  or  written
and whether express or implied) which are not expressly set forth in this Agreement have been made or entered into by either
party with respect to the subject matter hereof.  This Agreement supersedes any agreement (or portion thereof) concerning similar
subject  matter  dated  prior  to  the  date  of  this  Agreement,  and  by  execution  of  this  Agreement  both  parties  agree  that  any  such
predecessor agreement (or portion thereof) shall be deemed null and void.  For the avoidance of doubt, the parties agree that this
Agreement does not supersede the provisions of Executive’s Offer Letter that do not address termination or severance benefits or
Executive’s Employee Confidential Information and Invention Assignment Agreement with the Company.

Choice of Law.  The validity, interpretation, construction and performance of this Agreement shall
be governed by the laws of the State of California without reference to conflict of laws provisions, and the parties hereto submit
to the exclusive jurisdiction of the state and federal courts of the State of California.

(d)

(e)

Severability.    If  any  term  or  provision  of  this  Agreement  or  the  application  thereof  to  any
circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective
as  to  such  jurisdiction  to  the  extent  of  such  invalidity  or  unenforceability  without  invalidating  or  rendering  unenforceable  the
remaining terms and provisions of this Agreement or the application of such terms and provisions to circumstances other than
those as to which it is held invalid or unenforceable, and a suitable and equitable term or provision shall be substituted therefor to
carry out, insofar as may be valid and enforceable, the intent and purpose of the invalid or unenforceable term or provision.

PERSONALIS, INC.

FIRST AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

(SENIOR VICE PRESIDENT, VICE PRESIDENT, OR EQUIVALENT INDIVIDUAL CONTRIBUTOR)

This  First  Amended  and  Restated  Executive  Severance  Agreement  (the  “Agreement”),  effective  as  of  February  23,
2022,  amends,  supersedes  and  restates  in  its  entirety  that  certain  Executive  Severance  Agreement  by  and  between  Aaron
Tachibana  (“Executive”)  and  Personalis,  Inc.  (the  “Company”)  dated  June  2,  2019.    This  Agreement  is  intended  to  provide
Executive with certain benefits described herein upon the occurrence of specific events.  

RECITALS

A.

The Company’s Board of Directors (the “Board”) believes it is in the best interests of the Company and its

shareholders to retain Executive and provide incentives to Executive to continue in the service of the Company.

B.

The Board further believes that it is imperative to provide Executive with certain benefits upon termination of
Executive’s  employment,  which  benefits  are  intended  to  provide  Executive  with  financial  security  and  sufficient  income  and
encouragement to Executive to remain with the Company.

C.

To  accomplish  the  foregoing  objectives,  the  Board  has  directed  the  Company,  upon  execution  of  this

Agreement by Executive, to agree to the terms provided in this Agreement.

Now  therefore,  in  consideration  of  the  mutual  promises,  covenants  and  agreements  contained  herein,  the

parties hereto agree as follows:

1.

At-Will  Employment.    Executive’s  employment  is  at-will,  which  means  that  the  Company  may  terminate
Executive’s  employment  at  any  time,  with  or  without  Cause  or  advance  notice.    Similarly,  Executive  may  resign  Executive’s
employment  at  any  time,  with  or  without  advance  notice,  and  with  or  without  Good  Reason.    Executive  shall  not  receive  any
compensation  of  any  kind,  including,  without  limitation,  equity  award  vesting  acceleration  and  severance  benefits,  following
Executive’s last day of employment with the Company, except as expressly provided herein.

2.

Benefits Upon Termination of Employment.

(a)

Termination in Connection with or Following a Change in Control.  If Executive’s employment
is terminated without Cause (as defined below) (and other than as a result of Executive’s death or disability), or Executive resigns
for Good Reason (as defined below), in either case within twelve (12) months after the effective date of a Change in Control (as
defined below), and provided such termination constitutes a “separation from service” (within the meaning

1.

 
 
 
 
 
 
of Treasury Regulation Section 1.409A-1(h), such termination a “Separation from Service”), and provided further that Executive
signs and allows to become effective a general release of all claims in favor of the Company in a form provided by the Company
(the “Release”), within sixty (60) days after Executive’s Separation from Service (the date that the Release becomes effective and
may no longer be revoked by Executive is referred to as the “Release Date”), then the Company shall provide Executive with the
following severance benefits (the “Change in Control Separation Benefits”):

The  Company  shall  pay  Executive  cash  severance  in  an  amount  equal  to  twelve  (12)
months of Executive’s then-current base salary, ignoring any decrease in base salary that forms the basis for Good Reason, less
all applicable withholdings and deductions, paid on the Company’s first regular payroll date following the Release Date.  

(i)

(ii)

Should  Executive  timely  elect  to  continue  Executive’s  medical,  dental  and/or  vision
insurance  benefits  pursuant  to  the  Consolidated  Omnibus  Budget  Reconciliation  Act  of  1985  (“COBRA”)  or  any  analogous
provisions of applicable state law, the Company shall pay Executive’s COBRA premiums for Executive and Executive’s eligible
dependents  (“COBRA  Premiums”)  for  a  period  of  twelve  (12)  months  following  Executive’s  Separation  from  Service  (the
“Change in Control Benefits Payment Period”) or, if earlier, the date upon which Executive obtains coverage under a medical
plan  by  a  subsequent  employer.   The  Company’s  obligation  to  pay  any  COBRA  Premiums  will  be  subject  to  the  then-current
requirements of COBRA and any other laws affecting the payment of COBRA premiums by the Company.  Notwithstanding the
foregoing, if the Company determines, in its sole discretion, that the Company cannot provide the COBRA Premiums without
potentially incurring financial costs or penalties under applicable law, the Company shall in lieu thereof pay Executive a taxable
cash  amount,  which  payment  shall  be  made  regardless  of  whether  Executive  elects  health  care  continuation  coverage  (the
“Health Care Benefit Payment”).  The Health Care Benefit Payment shall be paid in monthly installments on the same schedule
that the COBRA Premiums would otherwise have been paid to the insurer.  The Health Care Benefit Payment shall be equal to
the amount that the Company would have otherwise paid for COBRA Premiums (which amount shall be calculated based on the
premium  for  the  first  month  of  COBRA  coverage),  and  shall  be  paid  until  the  earlier  of:  (i)  the  date  the  Change  in  Control
Benefits Payment Period expires or (ii) the date upon which Executive obtains coverage under a medical plan by a subsequent
employer.

unvested equity compensation awards, effective immediately prior to such Separation from Service.  

(iii)

The  Company  shall  accelerate  the  vesting  of  each  of  Executive’s  then-outstanding

(b)

Termination  Not  in  Connection  with  or  Following  a  Change  in  Control.    If  Executive’s
employment is terminated without Cause (and other than as a result of Executive’s death or disability), or Executive resigns for
Good  Reason,  in  either  case  at  any  time  that  is  not  within  twelve  (12)  months  after  a  Change  in  Control,  and  provided  such
termination  constitutes  a  Separation  from  Service,  and  provided  Executive  signs  and  allows  to  become  effective  the  Release
within sixty (60) days after Executive’s Separation from Service, then the Company shall provide Executive with the following
severance benefits (collectively with the Change in Control Separation Benefits, the “Separation Benefits”):

2.

 
 
 
The Company shall pay Executive cash severance in an amount equal to six (6) months of
Executive’s then current base salary, less all applicable withholdings and deductions, paid in a lump sum on the Company’s first
regular payroll date after the Release Date.

(i)

(ii)

Should  Executive  timely  elect  to  continue  Executive’s  medical,  dental  and/or  vision
insurance benefits pursuant to COBRA, the Company shall pay the COBRA Premiums for a period of six (6) months following
the  effective  date  of  Executive’s  Separation  from  Service  (the  “Benefits Payment Period”)  or,  if  earlier,  the  date  upon  which
Executive  obtains  coverage  under  a  medical  plan  by  a  subsequent  employer.    The  Company’s  obligation  to  pay  any  COBRA
Premiums  will  be  subject  to  the  then-current  requirements  of  COBRA  and  any  other  laws  affecting  the  payment  of  COBRA
premiums  by  the  Company.    Notwithstanding  the  foregoing,  if  the  Company  determines,  in  its  sole  discretion,  that  it  cannot
provide the COBRA Premiums without potentially incurring financial costs or penalties under applicable law, the Company shall
in lieu thereof pay Executive the Health Care Benefit Payment in monthly installments on the same schedule that the COBRA
Premiums  would  otherwise  have  been  paid  to  the  insurer,  which  shall  be  paid  until  the  earlier  of:  (i)  the  date  the  Benefits
Payment Period expires or (ii) the date upon which Executive obtains coverage under a medical plan by a subsequent employer.

3.

Limitations and Conditions on Separation Benefits

(a)

Release Prior to Payment of Benefits. Prior to the payment or provision of
any of the Separation Benefits, Executive shall execute, and allow to become effective, the Release not later than sixty (60) days
following Executive’s Separation from Service.  Such Release shall specifically relate to all of Executive’s rights and claims in
existence at the time of such execution and shall confirm Executive’s continuing obligations to the Company (including but not
limited to obligations under any confidentiality and/or non-solicitation agreement with the Company).  No Separation Benefits
will be paid prior to the Release Date.

(b)

Income  and  Employment  Taxes.    Executive  agrees  that  Executive  shall  be  responsible  for  any
applicable  taxes  of  any  nature  (including  any  penalties  or  interest  that  may  apply  to  such  taxes)  that  the  Company  reasonably
determines apply to any payment made hereunder, that Executive’s receipt of any benefit hereunder is conditioned on Executive’s
satisfaction  of  any  applicable  withholding  or  similar  obligations  that  apply  to  such  benefit,  and  that  any  cash  payment  owed
hereunder will be reduced to satisfy any such withholding or similar obligations that may apply.

(c)

Compliance with Section 409A.  It is intended that each installment of the payments and benefits
provided for in this Agreement is a separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i).  For the
avoidance of doubt, it is intended that Separation Benefits set forth in this Agreement satisfy, to the greatest extent possible, the
exemptions  from,  or  comply  with,  the  application  of  Section  409A  of  the  Internal  Revenue  Code  of  1986,  as  amended  (the
“Code”) and Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9) (together, with any state law of similar
effect, “Section 409A”). However, if the Company (or, if applicable, the successor entity thereto) determines that the Separation
Benefits provided under this Agreement constitute “deferred compensation” under Section 409A and Executive is, on the date of
his or her Separation from Service, a “specified employee” of the

3.

 
 
 
Company  or  any  successor  entity  thereto,  as  such  term  is  defined  in  Section  409A(a)(2)(B)(i)  of  the  Code  (a  “Specified
Employee”), then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section
409A, the timing of the Separation Benefits described herein, as applicable, shall be delayed as follows: on the earlier to occur of
(i) the date that is six (6) months and one (1) business day after Executive’s Separation from Service, (ii) the date of Executive’s
death, or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation (such earlier date, the
“Delayed  Initial  Payment  Date”).  Upon  the  Delayed  Initial  Payment  Date,  the  Company  (or  the  successor  entity  thereto,  as
applicable)  shall  pay  to  Executive  a  lump  sum  amount  equal  to  the  applicable  benefit  that  Executive  would  otherwise  have
received through the Delayed Initial Payment Date if the commencement of the payment of the benefit had not been so delayed
pursuant to this Section 3(c), and any remaining payments due shall be paid as otherwise provided herein. No interest shall be
due on any amounts so deferred. If the Separation Benefits are not covered by one or more exemptions from the application of
Section 409A and the Release could become effective in the calendar year following the calendar year in which Executive has a
Separation  from  Service,  the  Release  will  not  be  deemed  effective  any  earlier  than  the  Release  Date.  To  the  extent  that  any
provision of this Agreement is ambiguous as to its exemption or compliance with Section 409A, the provision will be read in
such a manner so that all payments hereunder are exempt from Section 409A to the maximum permissible extent. To the extent
any  payment  under  this  Agreement  may  be  classified  as  a  “short-term  deferral”  within  the  meaning  of  Section  409A,  such
payment shall be deemed a short-term deferral, even if it may also qualify for an exemption from Section 409A under another
provision of Section 409A. With respect to reimbursements or in-kind benefits provided to Executive hereunder (or otherwise)
that are not exempt from Section 409A, the following rules shall apply: (i) the amount of expenses eligible for reimbursement, or
in-kind benefits provided, during any one of Executive’s taxable years shall not affect the expenses eligible for reimbursement, or
in-kind  benefit  to  be  provided  in  any  other  taxable  year,  (ii)  in  the  case  of  any  reimbursements  of  eligible  expenses,
reimbursement  shall  be  made  on  or  before  the  last  day  of  Executive’s  taxable  year  following  the  taxable  year  in  which  the
expense was incurred, and (iii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for
another benefit.

(d)

Related Matters.  Executive further acknowledges and agrees that as a condition to receipt of any
Separation  Benefits  (i)  Executive  must  comply  with  Executive’s  obligations  under  Executive’s  Employee  Confidential
Information  and  Invention  Assignment  Agreement;  and  (ii)  resign  from  all  Company  and  or  affiliate  positions,  including
membership on any Board (unless otherwise requested by the Company).

(e)

Successors.  Any successor to the Company (whether direct or indirect and whether by purchase,
lease,  merger,  consolidation,  liquidation  or  otherwise)  to  all  or  substantially  all  of  the  Company’s  business  and/or  assets  shall
assume the obligations under this Agreement and agree expressly to perform the obligations under this Agreement in the same
manner  and  to  the  same  extent  as  the  Company  would  be  required  to  perform  such  obligations  in  the  absence  of  a
succession.  The terms of this Agreement and all of Executive’s rights hereunder and thereunder shall inure to the benefit of, and
be  enforceable  by,  Executive’s  personal  or  legal  representatives,  executors,  administrators,  successors,  heirs,  distributees,
devisees and legatees.

4.

 
 
 
(f)

Notice.  Notices and all other communications contemplated by this Agreement shall be in writing
and  shall  be  deemed  to  have  been  duly  given  when  personally  delivered  or  when  mailed  by  U.S.  registered  or  certified  mail,
return receipt requested and postage prepaid.  Mailed notices to Executive shall be addressed to Executive at the home address
which Executive most recently communicated to the Company in writing.  In the case of the Company, mailed notices shall be
addressed to its corporate headquarters, and all notices shall be directed to the attention of its Chief Executive Officer.

Definitions.

(a)

Cause.  For purposes of this Agreement, “Cause”, as determined by the Board acting in good faith
and  based  on  information  then  known  to  it,  shall  mean  the  occurrence  of  one  or  more  of  the  following:  (i)  Executive’s  gross
negligence or knowing and willful action which is or is likely to be materially injurious to the Company; (ii) any intentional act
by  Executive  in  connection  with  his  responsibilities  as  an  employee  constituting  fraud  or  a  felony  crime;  (iii)  Executive’s
consistent  failure  to  report  for  work  or  perform  his  duties  as  directed  by  the  Company’s  Board  of  Directors;  (iv)  persistent  or
repeated  material  breach  of  this  Agreement  or  any  agreement  between  Executive  and  the  Company;  (v)  Executive  becoming
disqualified from holding office through his own act or omission; (vi) an unauthorized use or disclosure by the Executive of the
Company’s  confidential  information  or  trade  secrets,  which  use  or  disclosure  causes  material  harm  to  the  Company;  or  (vii)  a
material failure by the Executive to comply with the Company’s written policies or rules which is or is likely to be materially
injurious to the Company.

consummation of a transaction or series of transactions that results in any of the following:

(b)

Change  in  Control.    For  purposes  of  this  Agreement,  “Change  in  Control”  means  the

(i)

a merger, consolidation or similar corporate transaction involving (directly or indirectly)
the Company and, immediately following which the stockholders of the Company immediately prior thereto do not own, directly
or indirectly, outstanding voting securities representing more than fifty percent (50%) of the combined outstanding voting power
of  the  surviving  entity  in  such  merger,  consolidation  or  similar  corporate  transaction  or  more  than  fifty  percent  (50%)  of  the
combined  outstanding  voting  power  of  the  parent  of  the  surviving  entity  in  such  merger,  consolidation  or  similar  corporate
transaction; or

Company that occurs over a period of not more than twelve (12) months.

(ii)

a  sale  or  other  disposition  of  all  or  substantially  all  of  the  consolidated  assets  of  the

However, a Change in Control will not include (1) any consolidation or merger effected exclusively to change the domicile of the
Company,  or  (2)  any  transaction  or  series  of  transactions  principally  for  bona  fide  equity  financing  purposes  in  which  cash  is
received by the Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof. In
addition,  no  transaction  will  be  a  Change  in  Control  unless  it  is  also  “change  in  ownership  of  a  corporation”  or  “change  in
ownership of a substantial portion of a corporation’s assets” as defined under in Treasury Regulations Sections 1.409A-3(i)(5)(v)
and (vii) without regard to any alternative definitions thereunder.

5.

 
 
 
(c)

Good Reason. For purposes of this Agreement, “Good Reason” for Executive’s resignation of his
or her employment will exist following the occurrence of any of the following without Executive’s written consent: (i) a material
reduction in Executive’s base salary, which the parties agree is a reduction of at least ten percent (10%) of Executive’s base salary
(provided,  however,  that  such  reduction  will  not  be  considered  Good  Reason  if  made  in  connection  with  an  across-the-board
salary  reduction  affecting  all  members  of  management);  (ii)  a  material  reduction  in  Executive’s  duties,  responsibilities  and/or
authority, provided, however, that a change in job position (including a change in title) after or in connection with a Change in
Control  shall  not  be  deemed  a  “material  reduction”  in  and  of  itself  unless  Executive’s new duties are materially reduced from
Executive’s prior duties; (iii) a relocation of Executive’s principal place of employment to a place that increases Executive’s one-
way commute by more than fifty (50) miles as compared to Executive’s then-current principal place of employment immediately
prior  to  such  relocation;  or  (iv)  a  material  breach  by  the  Company  of  this  Agreement.    In  order  to  resign  for  Good  Reason,
Executive must provide written notice to the Board within thirty (30) days after the first occurrence of the event giving rise to
Good Reason setting forth the basis for Executive’s resignation, allow the Company at least thirty (30) days from receipt of such
written notice to cure such event, and if such event is not reasonably cured within such period, Executive must resign from all
positions Executive then holds with the Company not later than thirty (30) days after the expiration of the cure period or the date
of  notification  to  Executive  that  the  Company  will  not  so  cure.    Executive  understands  and  agrees  that  the  requirement  for
Executive’s performance of services within twenty (20) miles of Palo Alto, California does not give rise to Good Reason.

5.

Parachute Payments.

(a)

If  any  payment  or  benefit  (including  payments  and  benefits  pursuant  to  this  Agreement)  that
Executive  would  receive  in  connection  with  a  Change  in  Control  from  the  Company  or  otherwise  (“Transaction  Payment”)
would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be
subject  to  the  excise  tax  imposed  by  Section  4999  of  the  Code  (the  “Excise  Tax”),  then  the  Company  shall  cause  to  be
determined, before any amounts of the Transaction Payment are paid to Executive, which of the following two alternative forms
of  payment  would  result  in  Executive’s  receipt,  on  an  after-tax  basis,  of  the  greater  amount  of  the  Transaction  Payment
notwithstanding that all or some portion of the Transaction Payment may be subject to the Excise Tax: (1) payment in full of the
entire amount of the Transaction Payment (a “Full Payment”), or (2) payment of only a part of the Transaction Payment so that
Executive receives the largest payment possible without the imposition of the Excise Tax (a “Reduced Payment”).  For purposes
of determining whether to make a Full Payment or a Reduced Payment, the Company shall cause to be taken into account all
applicable  federal,  state  and  local  income  and  employment  taxes  and  the  Excise  Tax  (all  computed  at  the  highest  applicable
marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and
local  taxes).    If  a  Reduced  Payment  is  made,  (x)  Executive  shall  have  no  rights  to  any  additional  payments  and/or  benefits
constituting the Transaction Payment, and (y) reduction in payments and/or benefits shall occur in the manner that results in the
greatest economic benefit to Executive as determined in this paragraph (the “Reduction Method”).  If more than one method of
reduction will result in the same economic benefit, the portions of the Transaction Payment shall be reduced pro rata (the “Pro
Rata Reduction Method”).

6.

 
 
 
(b)

Notwithstanding any provision of subsection (a) above to the contrary, if the Reduction Method or
the Pro Rata Reduction Method would result in any portion of the Transaction Payment being subject to taxes pursuant to Section
409A  that  would  not  otherwise  be  subject  to  taxes  pursuant  to  Section  409A,  then  the  Reduction  Method  and/or  the  Pro  Rata
Reduction  Method,  as  the  case  may  be,  shall  be  modified  so  as  to  avoid  the  imposition  of  taxes  pursuant  to  Section  409A  as
follows:  (i) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for
Executive as determined on an after-tax basis; (ii) as a second priority, Transaction Payments that are contingent on future events
(e.g., being terminated without Cause), shall be reduced (or eliminated) before Transaction Payments that are not contingent on
future events; and (iii) as a third priority, Transaction Payments that are "deferred compensation" within the meaning of Section
409A shall be reduced (or eliminated) before Transaction Payments  that  are  not  deferred  compensation  within  the  meaning  of
Section 409A.

(c)

The  professional  firm  engaged  by  the  Company  for  general  tax  purposes  or  the  Company’s
corporate law firm as of the day prior to the effective date of the Change in Control shall make all determinations required to be
made  under  this  Section  5.    If  the  professional  firm  so  engaged  by  the  Company  is  serving  as  accountant  or  auditor  for  the
individual,  entity  or  group  effecting  the  Change  in  Control,  the  Company  shall  appoint  a  nationally  recognized  independent
registered  public  accounting  firm  to  make  the  determinations  required  hereunder.    The  Company  shall  bear  all  expenses  with
respect to the determinations by such professional firm required to be made hereunder.

(d)

The professional firm engaged to make the determinations hereunder shall provide its calculations,
together with detailed supporting documentation, to the Company and Executive within fifteen (15) calendar days after the date
on which Executive’s right to a Transaction Payment is triggered or such other time as reasonably requested by the Company or
Executive.    If  the  professional  firm  determines  that  no  Excise  Tax  is  payable  with  respect  to  the  Transaction  Payment,  either
before  or  after  the  application  of  the  Reduced  Amount,  it  shall  furnish  the  Company  and  Executive  with  detailed  supporting
calculations of its determinations that no Excise Tax will be imposed with respect to such Transaction Payment.  Any good faith
determinations of the professional firm made hereunder shall be final, binding and conclusive upon the Company and Executive.

6.

Other  Employment  Terms  and  Conditions.    The  employment  relationship  between  the  parties  shall  be
governed  by  the  general  employment  policies  and  procedures  of  the  Company,  including  those  relating  to  the  protection  of
confidential information and assignment of inventions; provided, however, that when the terms of this Agreement differ from or
are in conflict with the Company’s general employment policies or procedures, this Agreement shall control.

7.

Dispute Resolution.  

(a)

Executive  and  the  Company  agree  that  any  and  all  disputes,  claims,  or  causes  of  action,  in  law  or  equity,
including but not limited to statutory claims, arising from or relating to the enforcement, breach, performance, or interpretation of
this  Agreement,  Executive’s  employment  with  the  Company,  or  the  termination  of  Executive’s  employment,  shall  be  resolved
pursuant to the Federal Arbitration Act, 9 U.S.C. § 1-16 (“FAA”), to the fullest extent permitted

7.

 
 
 
by law, by final, binding and confidential arbitration conducted by JAMS or its successor, under JAMS’ then applicable rules and
procedures  for  employment  disputes  before  a  single  arbitrator  (available  upon  request  and  also  currently  available  at
http://www.jamsadr.com/rules-employment-arbitration/), in San Jose, California. Executive acknowledges  that  by  agreeing  to
this arbitration procedure, both Executive and the Company waive the right to resolve any such dispute through a trial by
jury or judge or administrative proceeding.  

(b)

All  claims,  disputes,  or  causes  of  action  under  this  arbitration  agreement,  whether  by  Executive  or  the
Company, must be brought in an individual capacity, and shall not be brought as a plaintiff (or claimant) or class member in any
purported  class  or  representative  proceeding,  nor  joined  or  consolidated  with  the  claims  of  any  other  person  or  entity.    The
arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative
or  class  proceeding.    To  the  extent  that  the  preceding  sentences  regarding  class  claims  or  proceedings  are  found  to  violate
applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class shall proceed in a court
of law rather than by arbitration.  

(c)

This  arbitration  agreement  shall  not  apply  to  any  action  or  claim  that  cannot  be  subject  to  mandatory
arbitration as a matter of law, including, without limitation, sexual assault disputes and sexual harassment disputes as defined in
the  FAA,  claims  brought  pursuant  to  the  California  Private  Attorneys  General  Act  of  2004,  as  amended,  the  California  Fair
Employment  and  Housing  Act,  as  amended,  and  the  California  Labor  Code,  as  amended,  to  the  extent  such  claims  are  not
permitted  by  applicable  law(s)  to  be  submitted  to  mandatory  arbitration  and  the  applicable  law(s)  are  not  preempted  by  the
Federal  Arbitration  Act  or  otherwise  invalid  (collectively,  the  “Excluded  Claims”).    In  the  event  Executive  intends  to  bring
multiple claims, including one of the Excluded Claims listed above, the Excluded Claims may be filed with a court, while any
other claims will remain subject to mandatory arbitration.  Executive will have the right to be represented by legal counsel at any
arbitration proceeding.  

(d)

Questions  of  whether  a  claim  is  subject  to  arbitration  under  this  agreement  shall  be  decided  by  the
arbitrator.  Likewise, procedural questions which grow out of the dispute and bear on the final disposition are also matters for the
arbitrator.  The arbitrator shall: (i) have the authority to compel adequate discovery for the resolution of the dispute and to award
such  relief  as  would  otherwise  be  permitted  by  law;  and  (ii)  issue  a  written  statement  signed  by  the  arbitrator  regarding  the
disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential
findings and conclusions on which the award is based.  The arbitrator shall be authorized to award all relief that Executive or the
Company  would  be  entitled  to  seek  in  a  court  of  law.    The  Company  shall  pay  all  JAMS  arbitration  fees  in  excess  of  the
administrative  fees  that  Executive  would  be  required  to  pay  if  the  dispute  were  decided  in  a  court  of  law.    Nothing  in  this
arbitration agreement is intended to prevent either Executive or the Company from obtaining injunctive relief in court to prevent
irreparable harm pending the conclusion of any such arbitration.  Any awards or orders in such arbitrations may be entered and
enforced as judgments in the federal and state courts of any competent jurisdiction.

Miscellaneous Provisions.

8.

8.

 
 
 
No  Duty  to  Mitigate.    Executive  shall  not  be  required  to  mitigate  the  amount  of  any  payment
contemplated by this Agreement (whether by seeking new employment or in any other manner), nor shall any such payment be
reduced by any earnings that Executive may receive from any other source.

(a)

(b)

Waiver.    No  provision  of  this  Agreement  shall  be  modified,  waived  or  discharged  unless  the
modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company
(other than Executive).  No waiver by either party of any breach of, or of compliance with, any condition or provision of this
Agreement  by  the  other  party  shall  be  considered  a  waiver  of  any  other  condition  or  provision  or  of  the  same  condition  or
provision at another time.

(c)

Whole  Agreement.    No  agreements,  representations  or  understandings  (whether  oral  or  written
and whether express or implied) which are not expressly set forth in this Agreement have been made or entered into by either
party with respect to the subject matter hereof.  This Agreement supersedes any agreement (or portion thereof) concerning similar
subject  matter  dated  prior  to  the  date  of  this  Agreement,  and  by  execution  of  this  Agreement  both  parties  agree  that  any  such
predecessor agreement (or portion thereof) shall be deemed null and void.  For the avoidance of doubt, the parties agree that this
Agreement does not supersede the provisions of Executive’s Offer Letter that do not address termination or severance benefits or
Executive’s Employee Confidential Information and Invention Assignment Agreement with the Company.

Choice of Law.  The validity, interpretation, construction and performance of this Agreement shall
be governed by the laws of the State of California without reference to conflict of laws provisions, and the parties hereto submit
to the exclusive jurisdiction of the state and federal courts of the State of California.

(d)

(e)

Severability.    If  any  term  or  provision  of  this  Agreement  or  the  application  thereof  to  any
circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective
as  to  such  jurisdiction  to  the  extent  of  such  invalidity  or  unenforceability  without  invalidating  or  rendering  unenforceable  the
remaining terms and provisions of this Agreement or the application of such terms and provisions to circumstances other than
those as to which it is held invalid or unenforceable, and a suitable and equitable term or provision shall be substituted therefor to
carry out, insofar as may be valid and enforceable, the intent and purpose of the invalid or unenforceable term or provision.

Legal  Fees  and  Expenses.   The  parties  shall  each  bear  their  own  expenses,  legal  fees  and  other

(g)

No  Assignment  of  Benefits.    The  rights  of  any  person  to  payments  or  benefits  under  this
Agreement shall not be made subject to option or assignment, either by voluntary or involuntary assignment or by operation of
law, including (without limitation) bankruptcy, garnishment, attachment or other creditor’s process, and any action in violation of
this Section 8(g) shall be void.
