Item 1. Business.

Company Background

PART I

Personalis develops and markets advanced cancer genomic tests and analytics. Our tests and analytics are used by pharmaceutical companies 
for  translational  research,  biomarker  discovery,  the  development  of  personalized  cancer  therapies,  and  we  expect  in  the  near  future,  for  clinical  trial 
enrollment. Our advanced tests are used by physicians to detect cancer recurrence, monitor cancer evolution, and uncover insights for therapy selection. We 
also provide sequencing and data analysis services to support population sequencing initiatives.

We perform large-scale, high quality next-generation sequencing ("NGS") in our Clinical Laboratory Improvement Amendments of 1988 (“CLIA”) 
certified  and  College  of  American  Pathologists  (“CAP”)  accredited  100,000  square  foot  laboratory  located  in  Fremont,  California.  We  were  incorporated 
under the laws of the state of Delaware in 2011 under the name Personalis, Inc. and became a publicly-traded company in 2019.

Products

For pharmaceutical and biopharmaceutical companies

NeXT Personal

NeXT  Personal  is  a  tumor-informed  liquid  biopsy  test  for  detection  of  minimal  residual  disease  ("MRD")  and  recurrence  in  cancer.  It  delivers 
industry-leading, ultra-high analytical sensitivity, which we believe allows for detection of cancer earlier than other technologies. NeXT Personal answers the 
questions: Does the patient have MRD? What are the kinetics of circulating tumor DNA ("ctDNA")?

ImmunoID NeXT

ImmunoID  NeXT  is  a  tissue-based  test  that  combines  whole  exome  (DNA)  and  whole  transcriptome  (RNA)  sequencing  data  with  advanced 
analytics to provide a multi-dimensional view of the tumor and the tumor microenvironment from a single sample. It is designed to enable the development of 
more efficacious cancer immunotherapies and the next-generation of composite biomarkers to better predict patient response. ImmunoID NeXT answers the 
question: What are the composite biomarkers in the tumor and the tumor microenvironment?

For cancer patients

NeXT Personal Dx

NeXT  Personal  Dx  is  a  tumor-informed  liquid  biopsy  test  for  detection  of  MRD  and  recurrence  in  cancer.  We  believe  it  provides  for  earlier 
detection  of  cancer  than  other  technologies  and  has  been  shown  to  detect  cancer  recurrence  ahead  of  traditional  imaging.  It  is  designed  to  aid  decision 
making  throughout  a  patient's  cancer  journey.  NeXT  Personal  Dx  involves  an  initial  test  (whole  genome  sequencing  of  a  tumor  and  normal  sample)  and 
subsequent blood/plasma tests based on a tumor-informed personalized panel for each patient. NeXT Personal Dx answers the questions: Does the patient 
have MRD? Has the cancer returned?

NeXT Dx

NeXT  Dx  is  a  comprehensive  tumor  profiling  test  that  unlocks  the  entire  exome  (DNA)  and  transcriptome  (RNA)  with  matched  tumor-normal 
analysis. We believe it improves chances of finding an effective therapy or clinical trial. NeXT Dx answers the question: What are the actionable therapies 
and clinical trials for the patient?

For diagnostics companies and population sequencing initiatives

WES

products.

WGS

We  perform  whole  exome  sequencing  ("WES")  of  cancer  tissue  and  matched  blood  samples  for  diagnostic  companies  as  an  input  to  their 

We perform whole genome sequencing ("WGS") on human samples for research projects, such as population sequencing initiatives.

Markets and Distribution

Our  customers  include  pharmaceutical  companies,  biopharmaceutical  companies,  diagnostics  companies,  universities,  non-profits,  government 
entities, and patients. We sell through a small direct sales force, organized by geography. In November 2023, we entered into an agreement with Tempus AI, 
Inc. (formerly known as Tempus Labs, Inc., and referred to herein as "Tempus") to commercialize NeXT Personal Dx in the clinical diagnostics market. As a 
result, we will also leverage the sales force of Tempus beginning 

4

Table of Contents

in 2024. The principal markets for our products are in the United States, Europe (including the U.K.), and Asia-Pacific, which accounted for 90%, 8%, and 
2% of our revenue for the year ended December 31, 2023, respectively.

Clinical Evidence and Reimbursement

Generating clinical evidence is critical for driving adoption of our tests in the clinical market (i.e., for cancer patients). To this end, one of our key 
strategies  is  working  with  a  growing  number  of  leading  cancer  centers  and  world-class  academic  research  institutions  to  build  and  publish  the  clinical 
evidence-base to support our products and our key indications. Because of the ultra-high analytical sensitivity of our technology, we are initially focusing on 
three  indications:  breast  cancer,  lung  cancer,  and  immunotherapy  (IO)  monitoring.  We  have  collaborations  with  Cancer  Research  UK,  University  College 
London,  and  the  Francis  Crick  Institute  (the  TRACERx  study);  The  Royal  Marsden;  the  Vall  d'Hebron  Institute  of  Oncology  (VHIO);  Duke  University;  the 
Dana-Farber  Cancer  Institute;  University  Medical  Center  Hamburg-Eppendorf  (also  known  as  UKE);  and  Criterium  and  the  Academic  Breast  Cancer 
Consortium that will focus on building the evidence-base for our technology and these indications. If the key opinion leaders ("KOLs") we are collaborating 
with have a positive experience using our products, we are optimistic this will support broader use of our products by other KOLs, as well as clinicians in the 
future.

Furthermore,  generating  clinical  evidence  is  crucial  to  obtaining  reimbursement  coverage  from  Medicare  and  other  payors.  We  are  striving  to 
obtain reimbursement coverage for NeXT Personal Dx and NeXT Dx. In January 2024, we received a final Medicare coverage determination for our NeXT 
Dx offering, extended retroactively to August 29, 2023. We estimate that approximately half of new solid tumor cancer cases will be diagnosed in patients 
covered by Medicare. One of our 2024 goals is to submit for Medicare reimbursement for NeXT Personal Dx upon publication of compelling clinical evidence 
in three key indications.

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 Adela, Inc., BostonGene Corporation, 
Caris  Life  Sciences,  Inc.,  Foresight  Diagnostics  Inc.  (“Foresight”),  Freenome,  Inc.,  Fulgent  Genetics,  Inc.,  Geneseeq  Technology  Inc.,  GRAIL,  Guardant 
Health, Inc., Haystack Oncology, Inc., which was acquired by Quest Diagnostics Incorporated in June 2023, Invitae Corporation (which on February 13, 2024 
filed  a  voluntary  petition  to  commence  proceedings  under  chapter  11  of  title  11  of  the  United  States  Code  in  the  United  States  Bankruptcy  Court  for  the 
District  of  New  Jersey),  MedGenome  Inc.,  Myriad  Genetics,  Inc.,  Natera,  NeoGenomics,  Inc.,  Novogene  Corporation,  Predicine,  Inc.,  Roche  Molecular 
Systems, Inc., Tempus, Inc., and Veracyte, 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, Inc. ("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 high sensitivity and comprehensiveness of the data generated by our products. 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,  identifying  neoantigens,  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 efforts, particularly related to other novel 
assay technologies which may be applicable to the diagnosis and treatment of cancer and other diseases.

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  Accuracy  and  Content  Enhanced  ("ACE")  assay  and  NeXT  platform  technology,  including  claims  directed  to  methods  for  enriching 
nucleic  acids  from  a  sample  based  on  differences  in  various  genomic  features,  such  as  GC-content,  molecular  size,  presence  of  genetic 
variations or rearrangements, identification of biomedically interpretable variants, epigenetic modifications, and/or species-origin (e.g., human 
and non-human);

5

Table of Contents

•

•

•

•

hybrid  exome-genome  technologies,  including  claims  directed  to  methods  for  combining  exome  and/or  whole  genome  sequencing  data 
generated from a sample, along with the identification of other variants to identify or detect disease;

liquid  biopsy  methods,  including  claims  directed  to  methods  of  analyzing  sequenced  nucleic  acids  obtained  from  a  patient  sample  in 
comparison with nucleic acids representing the reference genome, obtained from a blood sample, to identify disease, or recommend a drug 
treatment;

clinical interpretation and neoantigen identification and prediction methods, including claims directed to methods of ranking genes associated 
with a phenotype and inheritance pattern or identifying neoantigens expressed in a disease sample that may be used for targeted treatments; 
and

personalized genetic testing assays, including claims directed to methods for using sequencing data to create a personalized genetic test to 
monitor cancer progression, identify neoantigen candidates for personalized cancer vaccine treatment, or detect the recurrence of disease at 
the earliest possible timepoint.

As of December 31, 2023, we own 27 issued U.S. patents and 14 issued foreign patents. 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 2042.

Supply of Materials

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  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  certain  agreements  and  purchase  arrangements  in  place  with  Illumina  to  satisfy  the  projected  needs  of  our 
laboratory operations.

Customer Concentration

We currently derive a significant portion of our revenue from Natera, Inc. ("Natera") under our partnership to provide advanced tumor analysis for 
use in Natera's MRD testing offerings. Natera accounted for 43%, 41%, and 10% of our revenue for the years ended December 31, 2023, 2022, and 2021, 
respectively. We previously derived a significant portion of our revenue from the U.S. Department of Veterans Affairs Million Veteran Program ("VA MVP"), 
which is a large-scale population sequencing initiative. VA MVP accounted for 13%, 13%, and 53% of our revenue for the years ended December 31, 2023, 
2022, and 2021, respectively. Our top five customers, including the VA MVP and Natera, accounted for 74%, 76% and 84% of our revenue for the years 
ended December 31, 2023, 2022 and 2021, respectively.

Segments

We manage our business as one operating segment, which is the sale of sequencing and data analysis services.

Regulatory Environment

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  Personal  Dx  offering,  is  uncertain.  If  we  are  inadequately  covered  by  insurance  or  ineligible  for 
such reimbursement, this could limit our ability to market tests in the future. 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 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 

6

Table of Contents

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, including 
Maryland,  Pennsylvania,  Rhode  Island,  and  New  York.  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 (“FDC Act”), the FDA has jurisdiction over medical devices, which are 
defined to include, among other things, in vitro diagnostic devices (“IVDs”). The FDA regulates, among other things, the research, design, development, pre-
clinical  and  clinical  testing,  manufacturing,  safety,  effectiveness,  packaging,  labeling,  storage,  recordkeeping,  pre-market  clearance  or  approval,  adverse 
event reporting, marketing, promotion, sales, distribution, and import and export of medical devices. Unless an exemption applies, each new or significantly 
modified medical device we seek to commercially distribute in the United States will require either a premarket notification to the FDA requesting permission 
for commercial distribution under Section 510(k) of the FDC Act, also referred to as a 510(k) clearance, or approval from the FDA of a 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 tests as LDTs. 

On October 3, 2023, the FDA published a Notice of Proposed Rulemaking (the “Proposed Rule”) to regulate LDTs as medical devices under the 
FDC Act. The Proposed Rule outlines a 5-stage, 4-year, risk-based timeline for all LDTs to come within the existing medical device regulatory framework. In 
early December 2023, following the close of a public comment period, the FDA announced its intention to publish the Proposed Rule in final form in April 
2024. On January 18, 2024, the Director of FDA’s Center for Devices and Radiological Health, which oversees IVD regulation within the FDA, and the Chief 
Medical  Officer  and  Acting  Director  of  CMS’  Center  for  Clinical  Standards  and  Quality,  which  oversees  CLIA  within  CMS,  issued  a  joint  press  release 
supporting  the  Proposed  Rule,  indicating  broad  support  within  the  Department  of  Health  and  Human  Services  for  FDA’s  Proposed  Rule.  If  finalized  as 
proposed, we would be required to obtain PMA approval for certain of our tests by October 1, 2027. We would also be subject to device registration and 
listing requirements, medical device reporting requirements and the requirements of the FDA’s Quality System Regulation. 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 be required to submit 
one or more of our tests for premarket notification, review, clearance or approval by the FDA as medical devices.

If the FDA determines that our tests and associated software do not fall within the definition of an LDT, or the Proposed Rule is finalized in its 
present  form,  or  there  are  other  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.  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. On January 31, 2024, FDA announced its intent to initiate a reclassification process for most IVDs that are currently Class III (high risk), the majority 
of which are infectious disease and companion diagnostic IVDs, into Class II (moderate risk). This reclassification would allow manufacturers of certain types 
of  IVDs  to  seek  marketing  clearance  through  the  less  burdensome  Class  II  510(k)  premarket  notification  pathway  rather  than  the  Class  III  premarket 
approval (PMA) pathway, the most stringent type of FDA medical device review.

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.

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  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.

  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, 

8

 
Table of Contents

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 payor 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 payors, 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 Statute, EKRA’s reach extends beyond federal health care programs to include
private insurance (i.e., it is an “all payor” 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 payor is billed at a rate that exceeds the performing laboratory’s charges to the 
billing physician or supplier, and the performing laboratory could be at risk under false claims laws, described below, for causing the submission of a false 
claim.

The “14-Day Rule,” also known as the Medicare Date of Service Rule, prohibits a laboratory supplier from billing the Medicare program for tests 
performed on samples collected during or within 14 days of an inpatient hospital stay, unless an exception applies, and requires the laboratory supplier to bill 
the hospital in those cases. Penalties may apply to the laboratory supplier if Medicare determines that the Medicare program was inappropriately billed for 
testing that should have been billed to the hospital where the sample was collected.

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

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

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

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

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

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

U.S. Healthcare Reform

In the United States, there have been a number of legislative and regulatory changes at the federal and state levels that seek to reduce healthcare 
costs and improve the quality of healthcare. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care 
and Education Reconciliation Act (collectively, the “ACA”), became law. This law substantially changed the way health care is financed by both commercial 
payors and government payors, 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. Further, on

August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 (“IRA 2022”) into law, which among other things, extends enhanced subsidies 
for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA 2022 also eliminates the “donut hole” under the 
Medicare  Part  D  program  beginning  in  2025  by  significantly  lowering  the  beneficiary  maximum  out-of-pocket  cost  and  through  a  newly  established 
manufacturer discount program. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. 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 until 2032, unless additional Congressional action is taken. On January 2, 2013, the American 
Taxpayer  Relief  Act  of  2012  was  signed  into  law,  which,  among  other  things,  reduced  Medicare  payments  to  several  providers,  including  hospitals,  and 
increased the statute of limitations period for the government to recover overpayments to providers from three to five years. The Medicare Access and CHIP 
Reauthorization  Act  of  2015,  enacted  on  April  16,  2015  (“MACRA”),  repealed  the  formula  by  which  Medicare  made  annual  payment  adjustments  to 
physicians and replaced the former 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”). Under both APMs and MIPS, performance data collected each performance year will affect Medicare 
payments in later years, including potentially reducing payments.

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  (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 payor 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. Beginning on January 1, 2018, CMS has begun using reported private payor pricing to 
periodically  revise  payment  rates  under  the  CLFS.  Based  on  current  law,  between  January  1,  2025  and  March  31,  2025,  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  2025  to  2027  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. Pursuant to the Coronavirus Aid, Relief, 
and Economic Security Act ("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 payors 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 payors, including commercial payors and government payors.

sourcing for candidates for new roles as well as education and a visible commitment to diversity and inclusion internally.

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 January 31, 2024, we had 225 employees, of which 223 were full-time employees. Of these full-time employees, 80 were in research and 
development, 70 in laboratory operations, 38 in commercial operations and 35 in general and administrative functions. 221 of our full-time employees were 
located in the United States, with the remaining two located in Europe (including the U.K.). As of January 31, 2024, more than 40% 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 Fremont, 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.

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 one of our largest customers, Natera, and in the past have 
derived a substantial portion of our revenue from another of our largest customers, the VA MVP.

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

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.

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 or 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.

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.

Failure or perceived failure to comply with existing or future laws, regulations, contracts, self-regulatory schemes, standards, and other obligations 
related to data privacy and security (including security incidents) could harm our business. Compliance or the actual or perceived failure to comply 
with such obligations could increase the cost of our offerings, limit their use or adoption, and otherwise negatively affect our operating results and 
business.

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

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 services and 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.

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.

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  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, 2023, 2022, and 2021 we had net losses of $108 million, 
$113  million  and  $65  million,  respectively.  As  of  December  31,  2023,  we  had  an  accumulated  deficit  of  $469  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  and  through  gaining  acceptance  in  medical  communities. 
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 educate 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.

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  educate  our  customers  and 
potential customers on the benefits of our comprehensive tests compared to 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 results in our 
customers’ or potential customers’ decision 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 Adela, Inc., BostonGene Corporation, Caris Life Sciences, Inc., Foresight Diagnostics Inc. 
(“Foresight”),  Freenome,  Inc.,  Fulgent  Genetics,  Inc.,  Geneseeq  Technology  Inc.,  GRAIL,  Guardant  Health,  Inc.,  Haystack  Oncology,  Inc.,  which  was 
acquired  by  Quest  Diagnostics  Incorporated  in  June  2023,  Invitae  Corporation,  MedGenome  Inc.,  Myriad  Genetics,  Inc.,  Natera,  NeoGenomics,  Inc., 
Novogene Corporation, Predicine, Inc., Roche Molecular Systems, Inc., Tempus, Inc., and Veracyte, Inc. may have more widespread brand recognition or 
substantially  greater  financial  or  technical  resources,  development  or  production  capacities,  or  marketing  capabilities  than  we  do.  They  may  be  able  to 
devote  greater  resources  to  the  development,  promotion  and  sale  of  their  products  and  services  than  we  do  or  sell  their  products  and  services  at  prices 
designed to win more significant levels of market share. 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 
the year ended December 31, 2023, revenue under our agreement accounted for 43% 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. 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 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 service or 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  and  products  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  one  of  our  largest  customers, 
Natera, and in the past have derived a substantial portion of our revenue from another of our largest customers, the VA MVP.

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 Natera, which accounted for 43%, 41%, and 10% of our revenue for the years ended December 31, 2023, 2022, and 
2021, respectively. We previously derived a significant portion of our revenue from the VA MVP, which more recently accounted for 13%, 13%, and 53% of 
our revenue for the years ended December 31, 2023, 2022, and 2021, respectively. Our top five customers, including the VA MVP and Natera, accounted for 
74%,  76%  and  84%  of  our  revenue  for  the  years  ended  December  31,  2023,  2022  and  2021,  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. Some of our customers have in the past suspended or terminated clinical trials or 
projects, received less funding than expected, experienced declining or delayed sales, or otherwise decided to reduce or eliminate their use of our services, 
and these and other customers may also do so in the future. As a result, we could be pressured to reduce the prices we charge for our services, which would 
have an adverse effect on our margins and financial position, and which would likely negatively affect our revenue and results of operations. In particular, if 
we  do  not  win  future  VA  MVP  renewals  with  a  value  comparable  to  that  of  our  historical  contracted  orders,  it  may  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 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 February 2021, we entered into a partnership in the field of personalized oncology with Natera, pairing our NeXT tumor profiling and diagnostic 
services  and  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, in 2023, revenue under our agreement accounted for 43% of our total revenue. In November 2023, we amended our 
agreement  to  extend  minimum  volume  commitments  through  the  end  of  2024.  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,  our  NeXT  Personal  test  is  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 

17

Table of Contents

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.

We have derived a substantial portion of our current revenue from DNA sequencing and data analysis services that we provided to one 
of our largest customers, 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, or if our new contract with the VA MVP were to be terminated, our business, financial condition, 
revenue and other operating results, and cash flows will be materially harmed.

We have derived 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. In September 2022, we entered into a new contract with the VA MVP 
to  continue  providing  them  WGS  services  and  received  an  initial  task  order  with  a  value  of  up  to  $10.0  million.  The  performance  period  under  the  new 
contract includes a base period of one year, with four one-year renewal option periods that may be exercised upon discretion of the VA MVP. In August 2023, 
we received notice of the VA MVP's intention to exercise its first renewal option period and received a second task order with a value of up to $7.5 million, 
subject to the receipt of samples from the VA MVP. There is no guarantee that the VA MVP will exercise any subsequent renewal option.

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, if any, for our services among other factors. For 
example,  the  VA  MVP  contracted  order  received  in  September  2020  had  a  value  of  $30.9  million,  whereas  the  VA  MVP  contracted  orders  received  in 
September 2021, 2022, and 2023 had values of $9.7 million, $10.0 million, and $7.5 million, respectively, which represents a substantial decline. 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. The priorities of the VA, the VA MVP, or the U.S. government may change, including in response to a health epidemic or 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) with a value comparable to 
that of our historical contracted orders, our business, financial condition, revenue and other operating results and cash flows may be materially harmed.

We have only recognized revenue under our VA MVP contract upon the receipt and processing of samples, and the timing and number of VA MVP 
samples we have received 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. The timing and number of VA MVP samples may also be 
negatively  affected  by  a  public  health  crisis.  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 values of the September 2021 
and 2022 VA MVP contracted orders 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. A health epidemic or pandemic may negatively impact the value of any potential new VA MVP contract or 
order.

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

Our customers other than the VA MVP 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 a public health crisis), failures in their clinical trials (which 
failures  are  statistically  much  more  likely  to  occur  than  not  at  some  point  in  the  clinical  development  process,  notwithstanding  any  enhanced  patient 
stratification from the use of our proprietary tests and algorithms), 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.

When we 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 developed tests, including our NeXT Dx and NeXT Personal Dx 
products, is uncertain. We are seeking reimbursement for our NeXT Dx and NeXT Personal Dx tests, and 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 derive revenue from any such current 
or future tests. The commercial success of current or future services and 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, 
or  equivalent  foreign  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 current or future in vitro diagnostic tests that we develop. These payors may conclude that our services or 
products are less safe, less effective, or less cost-effective than existing or later-introduced services or 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 current or future in vitro 
diagnostic tests we develop for insurance coverage and adequate reimbursement.

In  January  2024,  we  announced  that  we  received  a  final  Medicare  coverage  determination  for  our  NeXT  Dx  offering,  extended  retroactively  to 
August  29,  2023.  While  we  estimate  that  approximately  half  of  new  solid  tumor  cancer  cases  will  be  diagnosed  in  patients  covered  by  Medicare,  the 
Medicare coverage determination may not be indicative of our ability to obtain coverage with other payors. Even if favorable coverage and reimbursement 
status is attained for one or more of our products, less favorable coverage policies and reimbursement rates may be implemented in the future.

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 our 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. Any disruption in Illumina’s operations or our inability to negotiate pricing with 
Illumina  on  acceptable  terms,  or  at  all,  could  negatively  impact  our  supply  chain  and  laboratory  operations  and  our  ability  to  conduct  our  business  and 
generate  revenue.  Additionally,  COVID-19  previously  disrupted  Illumina’s  ability  to  fulfill  our  purchase  orders  for  reagents  or  other  materials  in  a  timely 
manner and another health epidemic or pandemic may disrupt the ability of Illumina and our other suppliers to fulfill our purchase orders in a timely manner 
or at all. Our suppliers, including Illumina, could cease supplying these materials and equipment at any time, could increase the price of these materials or 
equipment (including the promotional pricing offered to us by Illumina for our 2022 VA MVP Agreement and certain other projects) 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.  We  have  also 
experienced,  and  may  experience  in  the  future,  delays  or  difficulties  in  upgrading  to  newer  versions  or  replacements  of  these  materials  and  equipment, 
which may have better performance or be more cost-effective than the current versions. Any such interruption, delay or difficulty 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 

19

Table of Contents

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 Files that we filed with the FDA, which are focused on the technology, quality management, and validation of our 
platform,  specifically  on  its  use  for  the  development  of  personalized  immunotherapies,  are  predicated  on  our  use  of  specified  equipment  and  processes, 
including  Illumina  sequencers  and  related  equipment.  The  detailed  information  in  the  Device  Master  Files  is  not  shared  with  our  customers,  but  with  our 
permission they can reference our FDA file numbers 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 Files 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 Files, which would cause us 
to lose a competitive advantage.

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, our only clinical reference or research and 
development laboratory facilities are 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. Northern California continues to experience 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. For example, from January 2023 
through April 2023, we experienced substantial disruption to our use of the Fremont facility due to a failure of an electrical bus duct serving the facility. See 
“—The  process  of  opening  our  new  laboratory  facilities  in  Fremont,  California  has  diverted  and  could  continue  to  divert  management’s  attention  and  has 
disrupted  and  could  continue  to  disrupt  our  ongoing  business.”  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,  and  our  services  typically  involve  using  biological  samples  provided  by  or  on  behalf  of  our  customers  or  collaborators.  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, or if these 
biological  samples  or  the  resulting  data  were  otherwise  lost,  damaged  or  compromised  due  to  equipment  malfunction,  human  error  or  other  causes,  our 
ability  to  pursue  our  research  and  development  projects  or  provide  our  services,  as  well  as  our  reputation,  could  be  jeopardized.  For  example,  we  have 
experienced from time to time, and may experience in the future, equipment malfunctions that have resulted in lost, damaged or compromised samples or 
resulting data. We carry insurance for damage to our property or to our customer's property while in our possession, and we also carry insurance for the 
disruption  of  our  business,  but  these  types  of  insurance  may  not  be  sufficient  to  cover  all  of  our  potential  losses  or  liabilities  and  may  not  continue  to  be 
available to us on acceptable terms, if at all.

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

Our success depends on our ability to provide reliable 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.

20

Table of Contents

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

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

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

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

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

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

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

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

In the European Economic Area (and Northern Ireland) (“EEA”), in order to place an in vitro diagnostic medical device ("IVD"), or an accessory to
an  IVD,  on  the  market,  or  put  it  into  service  in  the  EEA,  the  device  must  be  designed,  developed,  manufactured  and  marketed  in  compliance  with  the 
relevant  legal  framework.  On  May  26,  2022,  the  Regulation  on  In-Vitro  Diagnostic  Devices  (Regulation  (EU)  2017/746)  (“IVDR”)  entered  into  application, 
repealing  and  replacing  the  Directive  on  In-Vitro  Diagnostic  Devices  (98/79/EC)  (the  “IVDD”).  The  IVDR  and  its  associated  guidance  documents  and 
harmonized  standards  govern,  among  other  things,  device  design  and  development,  preclinical  and  clinical  or  performance  testing,  premarket  conformity 
assessment,  registration  and  listing,  manufacturing,  labeling,  storage,  claims,  sales  and  distribution,  export  and  import  and  post-market  surveillance, 
vigilance, and market surveillance. IVDs must comply with the General Safety and Performance Requirements (“GSPRs”) set out in Annex I of the IVDR.
Compliance with these requirements is a prerequisite to be able to affix the CE Mark to IVDs, without which they cannot be marketed or sold in the EEA.

In accordance with the IVDR, devices that are not placed on the market but are used within the context of a commercial activity, whether in return 
for payment or free of charge, for the provision of a diagnostic or therapeutic service offered by means of information society services, as defined in point (b) 
of Article 1(1) of Directive (EU) 2015/1535, or by other means of communication, directly or through intermediaries, to a natural or legal person established in 
the EEA (and Northern Ireland) will be subject to the IVDR. As a result, 

21

Table of Contents

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.

Fulfillment  of  the  obligations  imposed  by  the  IVDR  are  likely  to  increase  the  cost  and  time  required  in  order  to  obtain  regulatory  approval  for 
products and services in the EEA. If we offer tests or services to customers within the EEA (and Northern Ireland) (whether directly or via intermediaries) that 
fall  within  the  scope  of  the  IVDR,  we  may  be  unable  to  fulfill  these  obligations,  or  a  notified  body,  where  applicable,  may  consider  that  we  have  not 
adequately demonstrated compliance with our related obligations to merit a CE Certificate of Conformity on the basis of the IVDR. 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 tests or services to develop their own products or services will attain coverage and adequate reimbursement is unknown. In the U.S. and the 
EU,  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.

Physicians, hospitals, and third-party payors often are slow to adopt new products, services, 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. The collective efforts of each of our executives 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,  we  could  experience  difficulties  in  finding  qualified  successors,  competing  effectively,  developing  our 
technologies, and implementing our business strategy. Effective December 31, 2022, John West retired from his role as our Chief Executive Officer. Aaron 
Tachibana, our Chief Financial Officer, served as our interim Chief Executive Officer from December 31, 2022 until March 2, 2023, when Christopher Hall, 
who served as our SVP and Head, Diagnostics Business, was appointed Chief Executive Officer, in addition to his role as our President. As with any change 
in  leadership,  there  is  a  risk  to  organizational  effectiveness  and  employee  retention  as  well  as  the  potential  for  disruption  to  our  business.  Integrating 
members  into  new  or  different  management  roles  could  prove  disruptive  to  our  operations,  require  substantial  resources  and  management  attention  and 
ultimately prove unsuccessful. 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 or replace them 
in the event we lose their services. 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 self-employed or 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 have undertaken in the past, and may in the future undertake, internal restructuring activities that could result in disruptions to our 
business or otherwise harm our results of operations or financial condition.

From time to time we may undertake internal restructuring activities as we continue to evaluate and attempt to optimize our cost and operating 
structure in light of developments in our business strategy and long-term operating plans. For example, in the first quarter of 2023 and in the fourth quarter of 
2023, we implemented reductions in our workforce to reduce operating costs and improve operating efficiency that collectively affected nearly 50% of our
workforce. Any restructuring activities that we may undertake in the future may result in write-offs or other restructuring charges. There can be no assurance 
that  any  restructuring  activities  that  we  undertake  in  the  future  will  achieve  the  cost  savings,  operating  efficiencies  or  other  benefits  that  we  may  initially 
expect. Restructuring activities may also result in a loss of continuity, accumulated knowledge and inefficiency during transitional periods and thereafter. In 
addition, internal restructurings can require a significant amount of time and focus from management and other employees, which may divert attention from 
commercial operations and disrupt our ongoing business. If any internal restructuring activities we undertake in the future fail to achieve some or all of the 
expected benefits therefrom, our business, results of operations and financial condition could be materially and adversely affected.

The  process  of  opening  our  new  laboratory  facilities  in  Fremont,  California  has  diverted  and  could  continue  to  divert  management’s 
attention and has disrupted and could continue to disrupt our ongoing business.

We have relocated our corporate headquarters and all laboratory facilities to Fremont, California. These efforts have involved significant tenant 
improvements, construction and regulatory compliance activities to be undertaken. Such efforts have distracted and may continue to distract management 
from current operations, have disrupted and may continue to disrupt planned research, development or regulatory compliance activities, and have resulted in 
and  may  continue  to  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.  For  example,  delays  in  the  completion  of  updates  to  our  new  corporate  headquarters  in  Fremont 
delayed our previously planned move-in date. Additionally, from January 2023 through April 2023, we experienced substantial disruption to our use of the 
Fremont facility due to a failure of an electrical bus duct serving the facility. We used backup generators to power our laboratories and emergency lights at 
the facility through February 2023 but were unable to use the office portions of the facility, or use the facility's heating, ventilation and air conditioning system 
during this time. We were able to restore full power to the facility on a temporary basis during March 2023 and April 2023 using additional generators, and 
regular  electrical  service  to  the  facility  has  since  been  restored.  However,  we  may  experience  additional  disruptions  in  the  future.  We  incurred  costs  in 
maintaining  temporary  power  to  the  facility  and  in  attempting  to  permanently  remedy  the  problem,  including  obtaining  additional  backup  generators, 
equipment, and back up batteries, and purchasing fuel for the generators on a daily basis. If we experience additional disruptions to our power supply, it may 
result in a loss in productivity, including delays to research and development programs, and could render it difficult or impossible for us to sell or perform 
certain of our services for some period of time. Additionally, if the backup generators were to fail, it could result in damage to biological samples stored within 
the Fremont facility, which may include certain customer samples. See “—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 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 new facility 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.

We  may  need  to  continue  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.

Our  new  Fremont  facility  expanded  our  laboratory  capacity  and,  in  order  to  execute  our  business  model,  we  may  need  to  make  additional 
investments  to  further  scale  our  infrastructure,  including  purchases  of  additional  equipment,  some  of  which  can  take  several  months  or  more  to  procure, 
setup, and validate, or increases to our software and computing capacity. There is no assurance that any of these increases in scale, equipment, software, 
and computing capacities, or process enhancements will be successfully implemented. 

We expanded our laboratory facilities 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, or at all. If we fail to generate demand 
commensurate with our infrastructure growth or if we fail to scale our infrastructure sufficiently in advance of demand to successfully meet such demand, our 
business, prospects, financial condition, and results of operations could be adversely affected.

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

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  Tempus;  Myriad;  ClearNote  Health,  Inc.;  Cancer  Research  UK,  University  College  London,  and  the  Francis 
Crick Institute (the TRACERx study); The Royal Marsden; the Vall d'Hebron Institute of Oncology (VHIO); Duke University; the Dana-Farber Cancer Institute; 
University Medical Center Hamburg-Eppendorf (also known as UKE); and Criterium and the Academic Breast Cancer Consortium) 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;

24

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 operations and employees face risks related to health crises 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  that  could  cause  significant  disruption  in  the  operations  of  our 
customers  and  third-party  suppliers  upon  whom  we  rely.  Our  laboratory  facilities,  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  were  previously  impacted  by  the  COVID-19  pandemic.  For  example,  the  previous  shelter-in-place  order  and  health  orders 
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 
cause similar effects on our operations. COVID-19 disrupted, and a future health epidemic or pandemic may disrupt in the future, the ability of our suppliers 
to fulfill our purchase orders in a timely manner or at all. Additionally, we use certain 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 a health epidemic or pandemic or if other supply chain issues 
arise as a result of such a public health crisis. Several of our customers were 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 in the event of the emergence of another health epidemic or pandemic.

Moreover, the ultimate impact of a health epidemic or pandemic on our business, operations, or the global economy as a whole is highly uncertain, 

but a continued and prolonged public health crisis could have a material negative impact on our business, financial condition, and operating results.

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.  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 Foreign Corrupt Practices Act of 1977, as amended (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, 

25

Table of Contents

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 or authorities determine that our tests do not appropriately comply 
with statutory and regulatory requirements enforced by the FDA, or equivalent foreign regulatory authorities and/or CLIA requirements 
for quality laboratory testing or equivalent foreign requirements.

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 
devices 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 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.

On October 3, 2023 FDA issued proposed regulations under which it would phase out its enforcement discretion approach to LDTs over a period 
of  four  years  (the  "Proposed  Rule").  If  the  Proposed  Rule  is  finalized  as  proposed,  we  anticipate  that  we  would  be  required  to  obtain  PMA  approval  for 
certain of our tests by October 1, 2027. We would also be subject to device registration and listing requirements, medical device reporting requirements and 
the requirements of the FDA’s Quality System Regulation. 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 be required to submit one or more of our tests for premarket notification, review, clearance or 
approval  by  the  FDA  as  medical  devices.  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.”

In early December 2023, following the close of a public comment period, FDA announced its intention to publish the Proposed Rule in final form in 
April 2024. On January 18, 2024, the Director of FDA’s Center for Devices and Radiological Health, which oversees IVD regulation within the FDA, and the 
Chief Medical Officer and Acting Director of CMS’ Center for Clinical Standards and Quality, which oversees CLIA within CMS, issued a joint press release 
supporting the Proposed Rule, indicating broad support within the Department of Health and Human Services for FDA’s Proposed Rule.

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. For example, the proposed “Verifying Accurate, Leading-edge IVCT Development” Act 
(the “VALID Act”) would clarify and enhance FDA’s authority to regulate LDTs, including premarket review of non-exempted tests. We cannot predict whether 
the VALID Act will become legislation and cannot provide any assurance that FDA regulation, including premarket review, will not be required in the future for 
our tests, whether through finalization of the Proposed Rule, 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  such  as  the  Proposed  Rule  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. In addition, 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.

In the EEA, IVDs are governed by the IVDR and must comply with the requirements of the IVDR in order to be placed on the market or put into 
service in the EEA. The IVDR does not specifically address the regulation of products falling within the description "laboratory-developed tests". Moreover, 
while  the  Regulation  includes  only  limited  exemptions  for  devices  that  are  manufactured  and  used  only  within  health  institutions  established  in  the  EEA, 
diagnostic  and  therapeutic  services  undertaken  outside  of  the  EEA  (for  example  at  our  facilities  in  the  U.S.)  would  not  fall  within  the  scope  of  such 
exemptions. We believe that we do not currently offer tests or services 

26

Table of Contents

to customers established in the EEA which would fall within the scope of the IVDR. If, in the future, we offer tests or services to customers within the EEA 
(whether  directly  or  via  intermediaries)  that  fall  within  the  scope  of  the  IVDR,  it  is  unlikely  that  we  will  benefit  from  IVDR  exemptions  foreseen  for  health 
institutions established in the EEA. This means that we will have to comply with the IVDR in full.

If the FDA determines that our services are subject to enforcement as medical devices, or if foreign regulatory authorities regulate our 
products as IVDs, we could incur substantial costs and time delays associated with satisfying statutory and regulatory requirements 
such as pre-market clearance, approval or certification, 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 such as FDA's Proposed Rule, 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  premarket  approval  application  (“PMA”).  We  would  also  be  subject  to  ongoing  regulatory  requirements  such  as  registration  and  listing 
requirements,  medical  device  reporting  requirements,  and  quality  control  requirements.  If  our  tests  are  considered  medical  devices  not  subject  to 
enforcement discretion, 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. On January 31, 2024, FDA announced its intent to 
initiate a reclassification process for most IVDs that are currently Class III (high risk), the majority of which are infectious disease and companion diagnostic 
IVDs, into Class II (moderate risk). This reclassification would allow manufacturers of certain types of IVDs to seek marketing clearance through the less 
burdensome  Class  II  510(k)  premarket  notification  pathway  rather  than  the  Class  III  premarket  approval  (PMA)  pathway,  the  most  stringent  type  of  FDA 
medical device review.

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 device 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. 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  service  and  product  development  costs,  delay  commercialization  of  any 
future  services  or  products,  and  interrupt  sales  of  our  current  services  and  products.  Many  of  the  factors  that  may  cause  or  lead  to  a  delay  in  the 
commencement or completion of clinical trials may also ultimately lead to delay or denial of regulatory clearance or approval. The commencement of clinical 
trials may be delayed due to insufficient patient enrollment, which is a function of many factors, including the size of the patient population, the concerns 
around genetic testing, the nature of the protocol, the proximity of patients to clinical sites, and the eligibility criteria for the clinical trial.

If we are required to conduct clinical trials, we and any third-party contractors we engage would be required to comply with good clinical practices 
(“GCPs”), which are regulations and guidelines enforced by the FDA, for devices 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. Similar actions and obligations may be imposed by the competent authorities of an EU Member State, 
or a foreign regulatory authority.

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 
devices 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 services and products. If premarket review is required for some or all of our services and products, the FDA may require 
that  we  stop  selling  such  services  and  products  pending  clearance  or  approval,  which  would  negatively  impact  our  business.  Even  if  our  services  and 
products are allowed to remain on the market prior to clearance or approval, demand for our services and products may decline if there is uncertainty about 
our services or products, if we are required to label our services or products as investigational by the FDA, or if the FDA limits the labeling claims we are 
permitted  to  make  for  our  services  or  products.  As  a  result,  we  could  experience  significantly  increased  development  costs  and  a  delay  in  generating 
additional revenue from our services and products, or from other services or products now in development.

In  addition,  any  clearance  or  approval  we  obtain  for  our  services  or  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 
services or 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 service or product marketing;

warning letters;

withdrawal or recall of services or 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 device’s FDA approved labeling. The FDA and other agencies or authorities 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, 

28

Table of Contents

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.

In addition, if we offer tests or services to customers within the EEA (and Northern Ireland) (whether directly or via intermediaries) that fall within 
the scope of the IVDR, we would be required to comply with strict requirements in order to affix the CE mark to our products, including requirements for 
clinical evidence, pre-market assessment of safety and performance, quality management system, traceability of products, promotion and advertising, and 
conduct costly post-market testing and surveillance to monitor the safety or effectiveness of our products in the EEA and detailed reporting obligations.

Failure to comply with federal, state, and foreign laboratory licensing requirements and the applicable requirements of the FDA or any 
other regulatory authority, or equivalent foreign 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 Fremont, California. To renew this certificate, we are subject to survey and inspection every two years. 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.

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, 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  test-specific  basis  by  New  York  as  an  out-of-state  laboratory,  and  our  LDTs  must  be  approved  by  the  New  York  State  Department  of 
Health (the “NYDOH”) on a test-by-test 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 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  for  our  clinical  reference  laboratory  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  by  the  regulatory  authorities  of  EU  Member  States  as  well  as 
repercussions  for  any  CE  Certificates  of  Conformity  issued  by  notified  bodies,  including  fines,  suspension  variation  or  withdrawal  of  CE  Certificates  of 
Conformity,  product  seizures,  injunctions  or  the  imposition  of  civil  or  criminal  penalties  which  would  adversely  affect  our  business,  operating  results  and 
prospects.

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  services  or  products  otherwise  fail  to  comply  with  FDA  regulatory  requirements  as 
enforced, or if we are required or 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 

29

Table of Contents

results of operations. In particular, if we or the FDA discover that any of our services or 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 services 
and 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  and  authorities  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  information  technology  systems  or  data,  or  those  of  third  parties  upon  which  we  rely,  are  or  were  compromised,  we  could 
experience adverse consequences resulting from such compromise, including but not limited to regulatory investigations or actions; 
litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers 
or sales; and other adverse consequences.

In the ordinary course of our business, we, and the third parties upon which we rely, collect, process, receive, generate, use, transfer, disclose, 
make accessible, protect, secure, dispose of, transmit, share and store (collectively, “process”) proprietary, confidential, and sensitive information, including 
protected health information (“PHI”), personal information, credit card and other financial information, intellectual property, trade secrets, medical information, 
biometric information and genomic information (collectively, “sensitive information”) owned or controlled by ourselves or our customers, payors, and other 
parties.

Cyberattacks, malicious internet-based activity, and online and offline fraud, and other similar activities threaten the confidentiality, integrity, and 
availability of our sensitive information and information technology systems, and those of the third parties upon which we rely. Such threats are prevalent and 
continue to increase, are becoming increasingly difficult to detect, and come from a variety of sources, including traditional computer “hackers,” threat actors, 
“hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated nation states, and nation-state-supported actors. 
Some actors now engage and are expected to continue to engage in cyberattacks, including without limitation nation-state actors for geopolitical reasons 
and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, including the war between Russia and Ukraine, 
the state of war between Israel and Hamas and the risk of a larger regional conflict, we, and the third parties upon which we rely, may be vulnerable to a 
heightened  risk  of  these  attacks,  including  retaliatory  cyberattacks,  that  could  materially  disrupt  our  systems  and  operations,  supply  chain,  and  ability  to 
produce, sell, and distribute our platform, products, and services.

We  and  the  third  parties  upon  which  we  rely  are  subject  to  a  variety  of  evolving  threats,  including  but  not  limited  to  social-engineering  attacks 
(including  through  deep  fakes,  which  may  be  increasingly  more  difficult  to  identify  as  fake,  and  phishing  attacks),  malicious  code  (such  as  viruses  and 
worms),  malware  (including  as  a  result  of  advanced  persistent  threat  intrusions),  denial-of-service  attacks,  credential  stuffing,  credential  harvesting, 
personnel  misconduct  or  error,  ransomware  attacks,  supply-chain  attacks,  software  bugs,  server  malfunctions,  attacks  enhanced  or  facilitated  by  artificial 
intelligence ("AI"), software or hardware failures, loss of data or other information technology assets, adware, telecommunications failures, natural disasters, 
terrorism,  and  other  similar  threats.  In  particular,  ransomware  attacks  are  becoming  increasingly  prevalent  and  severe  and  can  lead  to  significant 
interruptions in our operations, ability to provide our services, 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. Most of our employees are working remotely at least part of the time and such remote work has increased risks to our 
information technology systems and data, as more of our employees utilize network connections, computers and devices outside our premises or network, 
including working at home, while in transit and in public locations. Future or past business transactions (such as acquisitions or integrations) could expose us 
to additional cybersecurity risks and vulnerabilities, as our systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ 
systems and technologies. Furthermore, we may discover security issues that were not found during due diligence of such acquired or integrated entities, 
and it may be difficult to integrate companies into our information technology environment and security program.

We  rely  on  third-party  service  providers  and  technologies  to  operate  critical  business  systems  to  process  sensitive  information  in  a  variety  of 
contexts, including, without limitation, on-site systems and cloud-based data centers, systems handling human resources, financial reporting and controls, 
customer relationship management, regulatory compliance, and other infrastructure operations. 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 
sensitive  information,  including  research  and  development  information,  patient  data,  commercial  information,  and  business  and  financial  information.  Our 
ability to monitor these third parties’ security practices is limited, and these third parties may not have adequate security measures in place. If any of our 
third-party service providers experience a security incident or other interruption, we could experience adverse consequences. While we may be entitled to 
damages if any of our third-party service providers fail to satisfy their privacy or security-related obligations to us, any award may be insufficient to cover our 
damages, or we may be unable to recover such award. In addition, 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. 

Despite  the  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  2018,  we 
experienced downtime in our information technology systems in 

30

Table of Contents

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 of the previously identified or similar threats could cause a security incident or other interruption that could result in unauthorized, 
unlawful,  or  accidental  acquisition,  modification,  destruction,  loss,  alteration,  encryption,  disclosure  of,  or  access  to  our  sensitive  information  or  our 
information technology systems, or those of the third parties upon whom we rely. 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 data privacy and security obligations may require us to implement and maintain certain measures to protect our information 
technology systems and sensitive information.

While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will 
be  effective.  We  take  steps  designed  to  detect,  mitigate  and  remediate  vulnerabilities  in  our  information  systems  (such  as  our  hardware  and/or  software, 
including that of third parties upon which we rely). We may not, however, detect and remediate all such vulnerabilities, including on a timely basis. Further, 
we may experience delays in developing and deploying remedial measures and patches designed to address identified vulnerabilities, but we may not be 
able  to  detect  and  remediate  all  vulnerabilities  because  the  threats  and  techniques  used  to  exploit  the  vulnerability  change  frequently  and  are  often 
sophisticated in nature. Therefore, such vulnerabilities could be exploited but may not be detected until after a security incident has occurred. Further, if the 
information technology systems of the third parties upon which we rely become subject to security incidents, 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. Any of the previously identified or similar threats could cause a security incident or other interruption that could 
result  in  unauthorized,  unlawful,  or  accidental  acquisition,  modification,  destruction,  loss,  alteration,  encryption,  disclosure  of,  or  access  to  our  sensitive 
information or our information technology systems, or those of the third parties upon whom we rely. A security incident or other interruption could disrupt our 
ability (and that of third parties upon whom we rely) to provide our tests and services and otherwise conduct our business in the ordinary course.

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.  Further,  we  may  experience  delays  in  developing  and  deploying  remedial  measures 
designed to address any such identified vulnerabilities. For example, like many companies, we use Log4j with respect to certain software or systems to log 
security and performance information. In early 2022, we discovered a Log4j vulnerability in our environment although to date we have found no indication 
that  our  or  our  partners’  data  was  exposed.  Upon  learning  of  this  vulnerability,  we  applied  a  patch  and  made  updates  to  our  systems  and  infrastructure 
intended to reduce risks associated with the vulnerability.

Applicable data privacy and security obligations, including applicable federal and/or state breach notification laws and foreign equivalents, as well 
as  public  company  disclosure  obligations,  may  require  us  to  notify  relevant  stakeholders,  including  affected  individuals,  regulatory  authorities  and  our 
stockholders,  of  certain  security  incidents.  Such  disclosures  are  costly,  and  the  disclosure  or  the  failure  to  comply  with  such  requirements  could  lead  to 
adverse consequences. If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security incident, 
we may experience adverse consequences, such as government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); 
additional reporting requirements and/or oversight; restrictions on processing sensitive information (including personal information); litigation (including class 
claims)  and  mass  arbitration;  indemnification  obligations;  negative  publicity;  reputational  harm;  monetary  fund  diversions;  interruptions  in  our  operations 
(including availability of data); financial loss; and other similar harms. Security incidents and attendant consequences may prevent or cause customers or 
partners to stop using our platform, products, and services, deter new customers or partners from using our platform, products, and services, and negatively 
impact our ability to grow and operate our business. Whether a cybersecurity incident is reportable to our stockholders may not be straightforward, may take 
considerable time to determine, and may be subject to change as the investigation of the incident progresses, including changes that may significantly alter 
any initial disclosure that we provide.

Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in our contracts 
are  sufficient  to  protect  us  from  liabilities,  damages,  or  claims  related  to  our  data  privacy  and  security  obligations.  We  cannot  be  sure  that  our  insurance 
coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our data privacy and security practices. 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.

In addition to experiencing a security incident, third parties may gather, collect, or infer sensitive information about us from public sources, data 
brokers, or other means that reveals competitively sensitive details about our organization and could be used to undermine our competitive advantage or 
market  position.  Additionally,  our  sensitive  information  could  be  leaked,  disclosed,  or  revealed  as  a  result  of  or  in  connection  with  our  employee’s, 
personnel’s, or vendor’s use of generative AI technologies.

We are subject to stringent and evolving U.S. and foreign laws, regulations, rules, contractual obligations, industry standards, policies 
and other obligations related to data privacy and security. Our actual or perceived failure to comply with such obligations could lead to 
regulatory investigations or actions; litigation (including class claims) and mass arbitration demands; fines and penalties; disruptions 
of  our  business  operations;  reputational  harm;  loss  of  revenue  or  profits;  loss  of  customers  or  sales;  and  other  adverse  business 
consequences.

In  the  ordinary  course  of  business,  we  process  sensitive  information,  including  data  we  collect  from  our  customers  about  trial  participants  in 
connection with clinical trials. Our data processing activities subject us to numerous data privacy and security obligations, such as various laws, regulations, 
guidance, industry standards, external and internal privacy and security policies, contractual requirements, and other obligations relating to data privacy and 
security.

In  the  United  States,  federal,  state,  and  local  governments  have  enacted  numerous  data  privacy,  and  security  laws,  including  data  breach
notification  laws,  personal  information  privacy  laws,  and  consumer  protection  laws.  For  example,  the  Health  Insurance  Portability  and  Accountability  Act 
("HIPAA"), as amended by the Health Information Technology for Economic and Clinical Health Act ("HITECH"), imposes specific requirements relating to the 
privacy, security, and transmission of individually identifiable health information. Penalties for failure to comply with HIPAA and HITECH include significant 
civil monetary penalties and criminal penalties in certain circumstances with fines up to $250,000 per violation and/or imprisonment. 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 and applicable to us, we may 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.  Similarly,  the  California  Consumer 
Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020 (“CPRA”) (collectively, "CCPA") applies to personal information of consumers, 
business  representatives,  and  employees,  and  requires  businesses  to  provide  specific  disclosures  in  privacy  notices  and  honor  requests  of  California 
residents to exercise certain privacy rights, including those noted below. The CCPA provides for fines of up to $7,500 per intentional violation and allows 
private litigants affected by certain data breaches to recover significant statutory damages. Although the CCPA exempts some data processed in the context 
of  clinical  trials,  the  CCPA  increases  compliance  costs  and  potential  liability  with  respect  to  other  personal  information  we  maintain  about  California 
residents. In addition, the CPRA expands the CCPA’s requirements, including by adding a new right for individuals to correct their personal information and 
establishing a new regulatory agency to implement and enforce the law. Other states, such as Virginia, Colorado, Connecticut and Utah have also enacted 
comprehensive privacy laws, and similar laws are being considered in several other states, as well as at the federal and local levels. These state laws and 
the  CCPA  provide  individuals  with  certain  rights  concerning  their  personal  information,  including  the  right  to  access,  correct,  or  delete  certain  personal 
information, and opt-out of certain data processing activities, such as targeted advertising, profiling, and automated decision-making. The exercise of these 
rights may impact our business and ability to provide our products and services. While these states, like the CCPA, also exempt some data processed in the 
context of clinical trials, these developments further complicate compliance efforts, and increase legal risk and compliance costs for us, the third parties upon 
whom  we  rely  and  our  customers.  Additionally,  several  states  and  localities  have  enacted  statutes  banning  or  restricting  the  collection  of  biometric 
information  and  regulators,  such  as  the  Federal  Trade  Commission,  have  indicated  that  use  of  biometric  technologies  (including  facial  recognition 
technologies) may be subject to additional scrutiny.

We  may  be  subject  to  new  laws  governing  the  privacy  of  consumer  health  data,  including  reproductive,  sexual  orientation,  and  gender  identity 
privacy  rights.  For  example,  Washington’s  My  Health  My  Data  Act  (“MHMD”)  broadly  defines  consumer  health  data,  places  restrictions  on  processing 
consumer  health  data  (including  imposing  stringent  requirements  for  consents),  provides  consumers  certain  rights  with  respect  to  their  health  data,  and 
creates a private right of action to allow individuals to sue for violations of the law. Other states are considering and may adopt similar laws. California also 
recently passed a law protecting privacy of abortion-related records and other reproductive healthcare services.

Outside the U.S., an increasing number of laws, regulations, and industry standards govern data privacy and security. For example, the General 
Data Protection Regulation 2016/679 (“EU GDPR”), the United Kingdom’s GDPR (“UK GDPR”), Brazil’s General Data Protection Law (Lei Geral de Proteção 
de Dados Pessoais) (Law No. 13,709/2018), and China’s Personal Information Protection Law (“PIPL”) impose strict requirements for processing personal 
information. Under the EU GDPR and UK GDPR, companies may face temporary or definitive bans on data processing and other corrective actions; fines of 
up to 20 million Euros under the EU GDPR, 17.5 million pounds sterling under the UK GDPR or, in each case, 4% of annual global revenue, whichever is 
greater;  or  private  litigation  related  to  processing  of  personal  information  brought  by  classes  of  data  subjects  or  consumer  protection  organizations 
authorized at law to represent their interests. In Canada, the Personal Information Protection and Electronic Documents Act (“PIPEDA”) and various related 
provincial laws, as well as Canada’s Anti-Spam Legislation (“CASL”), applies to our operations. We also receive personal information from customers in Asia 
and may be subject to new and emerging data privacy and security regimes in Asia, including Japan’s Act on the Protection of Personal Information, and 
Singapore's Personal Data Protection Act.

In the ordinary course of business, we may transfer personal information from Europe and other jurisdictions to the U.S. or other countries. Europe 
and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal information to other countries. In particular, the 
EEA and the U.K. have significantly restricted the transfer of personal information to the U.S. and other countries whose data privacy and security laws they 
generally  believe  are  inadequate.  Other  jurisdictions  may  adopt  similarly  stringent  interpretations  of  their  data  localization  and  cross-border  data  transfer 
laws. Although there are currently various mechanisms that may be used to transfer personal information from the EEA and U.K. to the U.S. in compliance 
with  law,  such  as  the  EEA’s  standard  contractual  clauses,  the  U.K.'s  International  Data  Transfer  Agreement  /  Addendum,  and  the  EU-U.S.  Data  Privacy 
Framework (and U.K. extension thereto) (which allows for transfers for relevant U.S.-based organizations who self-certify compliance and participate in such 

32

Table of Contents

framework),  these  mechanisms  are  susceptible  to  legal  challenges,  and  there  is  no  assurance  that  we  can  satisfy  or  rely  on  these  measures  to  lawfully 
transfer personal information to the U.S. If there is no lawful manner for us to transfer personal information from the EEA, the U.K. or other jurisdictions to the 
U.S., or if the requirements for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including the interruption or 
degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions at significant expense, 
increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, 
and  injunctions  against  our  processing  or  transferring  of  personal  information  necessary  to  operate  our  business.  Additionally,  companies  that  transfer 
personal  information  out  of  the  EEA  and  U.K.  to  other  jurisdictions,  particularly  to  the  U.S.,  are  subject  to  increased  scrutiny  from  regulators,  individual 
litigants, and activist groups. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers out of Europe 
for allegedly violating the GDPR’s cross-border data transfer limitations. EEA countries may also introduce national legislation further limiting the processing 
of  personal  genetic,  biometric,  or  health  data,  which  could  limit  our  ability  to  collect,  use  and  share  data  originating  from  the  EEA,  or  could  cause  our 
compliance costs to increase, require us to change our practices, adversely impact our business, and harm our financial condition.

In addition to data privacy and security laws, because we process some credit card payments through a third-party payment processing partner, 
we are contractually subject to industry standards adopted by industry groups and may become subject to such obligations in the future. For example, we 
may  also  be  subject  to  the  Payment  Card  Industry  Data  Security  Standard  (“PCI  DSS”).  The  PCI  DSS  requires  companies  to  adopt  certain  measures  to 
ensure  the  security  of  cardholder  information,  including  using  and  maintaining  firewalls,  adopting  proper  password  protections  for  certain  devices  and 
software,  and  restricting  data  access.  Noncompliance  with  PCI-DSS  can  result  in  penalties  ranging  from  $5,000  to  $100,000  per  month  by  credit  card 
companies, litigation, damage to our reputation, and revenue losses.

We  also  rely  on  vendors  to  process  payment  card  data,  who  may  be  subject  to  PCI  DSS,  and  our  business  may  be  negatively  affected  if  our 
vendors are fined or suffer other consequences as a result of PCI DSS noncompliance. We are also bound by contractual obligations related to data privacy 
and  security,  and  our  efforts  to  comply  with  such  obligations  may  not  be  successful.  For  example,  certain  privacy  laws,  such  as  the  GDPR,  require  our 
customers  to  impose  specific  contractual  restrictions  on  their  service  providers.  We  publish  privacy  policies,  marketing  materials  and  other  statements 
regarding  data  privacy  and  security.  If  these  policies,  materials  or  statements  are  found  to  be  deficient,  lacking  in  transparency,  deceptive,  unfair,  or 
misrepresentative of our practices, we may be subject to investigation, enforcement actions by regulators or other adverse consequences.

Our employees and personnel may use generative AI technologies to perform their work, and the disclosure and use of personal information in 
generative AI technologies is subject to various data privacy laws and other privacy obligations. Governments have passed and are likely to pass additional 
laws regulating generative AI. Our use of this technology could result in additional compliance costs, regulatory investigations and actions, and consumer 
lawsuits. If we are unable to use generative AI, it could make our business less efficient and result in competitive disadvantages.

Obligations  related  to  data  privacy  and  security  (and  consumers'  data  privacy  and  security  expectations)  are  quickly  changing,  becoming 
increasingly  stringent,  and  creating  uncertainty.  Additionally,  these  obligations  may  be  subject  to  differing  applications  and  interpretations,  which  may  be 
inconsistent  or  conflict  among  jurisdictions.  Preparing  for  and  complying  with  these  obligations  requires  us  to  devote  significant  resources,  which  may 
necessitate  changes  to  our  platform,  products  and/or  services,  information  technologies,  systems,  and  practices  and  to  those  of  any  third  parties  that 
process  personal  information  on  our  behalf.  In  addition,  these  obligations  may  require  us  to  change  our  business  model.  Our  business  model  materially 
depends on our ability to process personal information, so we are particularly exposed to the risks associated with the rapidly changing legal landscape. For 
example, because we process PHI, personal information and sensitive information, we may be at heightened risk of regulatory scrutiny, and any changes in 
the regulatory framework could require us to fundamentally change our business model, including causing 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 particularly 
with respect to our RUO and clinical trial services, and we also typically rely on each provider ordering our LDTs or diagnostic services to obtain valid and 
appropriate consent from each of his or her patients whose genetic samples and data we process on such patient's behalf. Given that we do not typically 
obtain direct consent from such data subjects or patients, and we do not audit our customers or the ordering providers to ensure that they have obtained the 
necessary consents required by law, the failure of our customers or the order providers to obtain consents that are valid under applicable law could result in 
our own non-compliance with data privacy and security laws. For example, our NeXT Personal RUO test leverages WGS, and the scope of existing consents 
from  our  customers'  clinical  trial  subjects  may  be  insufficient  to  cover  use  of  NeXT  Personal  on  their  samples,  which  may  either  limit  uptake  of  NeXT 
Personal or expose our customers and ourselves to risk of exceeding the scope of prior consent for specimen testing. A failure, or a perceived failure, to 
address or comply with U.S. and foreign data privacy and security laws 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  data  privacy  and  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.

If  we  or  the  third  parties  on  which  we  rely  fail,  or  are  perceived  to  have  failed,  to  address  or  comply  with  applicable  data  privacy  and  security 
obligations,  we  could  face  significant  consequences,  including  but  not  limited  to:  government  enforcement  actions  (e.g.,  investigations,  fines,  penalties, 
audits, inspections, and similar); litigation (including class-action claims) and mass arbitration demands; additional reporting requirements and/or oversight; 
bans on processing personal information; orders to destroy or not use personal information; and imprisonment of company officials. In particular, plaintiffs 
have  become  increasingly  more  active  in  bringing  data  privacy-related  claims  against  companies,  including  class  claims  and  mass  arbitration  demands. 
Some of these claims allow for the recovery of 

33

Table of Contents

statutory damages on a per violation basis, and, if viable, carry the potential for monumental statutory damages, depending on the volume of data and the 
number of violations. Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: 
loss  of  customers; interruptions or stoppages in  our  business  operations  (including,  clinical  trials);  interruptions  or  stoppages  of  data  collection  needed  to 
train our algorithms; inability to process personal information or to operate in certain jurisdictions; limited ability to develop or commercialize our platform, 
products, and services; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or substantial changes to our business model or 
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, 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 payor is billed at a rate that exceeds the performing 
laboratory’s  charges  to  the  billing  physician  or  supplier,  and  the  performing  laboratory  could  be  at  risk  under  false  claims  laws,  described 
below, for causing the submission of a false claim;

the 14-Day Rule, also known as the Medicare Date of Service Rule, which prohibits a laboratory supplier from billing the Medicare program 
for tests performed on samples collected during or within 14 days of an inpatient hospital stay, unless an exception applies, and requires the 
laboratory supplier to bill the hospital in those cases. Penalties may apply to the laboratory supplier if Medicare determines that the Medicare 
program was inappropriately billed for testing that should have been billed to the hospital where the sample was collected; 

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 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 

34

Table of Contents

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  services  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 the Children’s 
Health Insurance Program, 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;

the  Eliminating  Kickbacks  in  Recovery  Act  of  2018  (“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  payor”  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 payor, 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  and  authorities  such  as  the 
Department  of  Justice,  the  U.S.  Department  of  Health  and  Human  Services  ("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 

35

Table of Contents

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,  disgorgement,  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 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.

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 payors and government payors, and significantly impacts 
our industry. The ACA contains a number of provisions that are expected to impact the business and operations of our customers, some of which in ways we 
cannot  currently  predict,  including  those  governing  enrollment  in  state  and  federal  health  care  programs,  reimbursement  changes,  and  fraud  and  abuse, 
which will impact existing state and federal health care programs and will result in the development of new programs.

Among other things, the ACA:

•

•

•

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

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

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

There  have  been  executive,  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.  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. Further, on August 16, 2022, 
President Biden signed the Inflation Reduction Act of 2022 (the “IRA 2022”) into law, which among other things, extends enhanced subsidies for individuals 
purchasing health insurance coverage in ACA marketplaces through plan year 2025. The IRA 2022 also eliminates the “donut hole” under the Medicare Part 
D program beginning

in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and through a newly established manufacturer discount program. 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 future 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 until 2032 unless additional Congressional action is taken. On January 2, 2013, the American 
Taxpayer  Relief  Act  of  2012  was  signed  into  law,  which,  among  other  things,  reduced  Medicare  payments  to  several  providers,  including  hospitals,  and 
increased the statute of limitations period for the government to recover overpayments to providers from three to five years. The Medicare Access and CHIP 
Reauthorization  Act  of  2015,  enacted  on  April  16,  2015  (“MACRA”)  repealed  the  formula  by  which  Medicare  made  annual  payment  adjustments  to 
physicians and replaced the former 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  APMs,  and  the  Merit-based  Incentive  Payment 
System. Under both APMs and MIPS, performance data collected each performance year will affect Medicare payments in later years, including potentially 
reducing payments.

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 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 payor 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. Beginning on January 1, 2018, CMS has begun using reported private payor pricing to periodically revise payment rates under the CLFS. Based 
on current law, between January 1, 2025 and March 31, 2025, 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 2025 to 2027 Clinical Laboratory Fee Schedule 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.

Pursuant to the Consolidated Appropriations Act, the statutory phase-in of the payment reductions has been extended through 2026 with a 0% 
reduction cap for 2021-2023 and a 15% reduction cap for 2024 through 2026. 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  payors  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 payors, including commercial payors and government payors. Therefore, even 
if favorable coverage and reimbursement status is attained, less favorable coverage policies and reimbursement rates may be implemented in the future.

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.

Changes in tax laws or regulations could adversely affect our business and financial condition.

On  December  22,  2017,  former  President  Trump  signed  into  law  comprehensive  tax  legislation  (the  “Tax  Cuts  and  Jobs  Act”)  that  significantly 
revised the Internal Revenue Code of 1986, as amended (the “Code”). Future guidance from the U.S. Internal Revenue Service and other tax authorities with 
respect to the Tax Cuts and Jobs Act may affect us, and certain aspects of the Tax Cuts and Jobs Act could be repealed or modified in future legislation. For 
example, on March 27, 2020, the CARES Act was enacted, which includes changes to the tax provisions that benefit business entities and makes certain 
technical corrections to the Tax Cuts and Jobs Act. On December 27, 2020, the Consolidated Appropriations Act, a coronavirus relief package that extended 
and  expanded  various  tax  provisions,  was  signed  into  law.  The  IRA  2022  includes  provisions  that  will  impact  the  U.S.  federal  income  taxation  of 
corporations, including imposing a minimum tax on the book income of certain large corporations and an excise tax on certain corporate stock repurchases 
that would be imposed on the corporation repurchasing such stock. 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, 

37

Table of Contents

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, IRA 2022, 
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  could  lead  to  further  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.  The  U.K.  and  the  EU  have  signed  the  EU-U.K.  Trade  and  Cooperation  Agreement  ("TCA"),  which  became 
provisionally applicable on January 1, 2021 and entered into force on May 1, 2021. This agreement provides details on how some aspects of the U.K. and 
EU's  relationship  will  operate  in  the  future.  However,  there  are  still  many  uncertainties.  On  May  26,  2022,  the  IVDR  entered  into  application  in  the  EU. 
However, the IVDR is not applicable in the U.K. In the U.K., IVDs are governed by the Medical Devices Regulations 2002 (SI 2002 No 618, as amended) (UK 
MDR 2002) which retains a regulatory framework similar to the framework set out by the IVDD. As a result, there will be some regulatory divergence in the
U.K. from the EU in light of the fact that the CE marking process is set out in EU law, which no longer applies in the U.K. The U.K. has devised a new route 
to  market  culminating  in  a  U.K.  Conformity  Assessed  ("UKCA")  mark  to  replace  the  CE  Mark  for  placing  IVDs  on  the  market  in  Great  Britain  (“G.B.”). 
Northern Ireland will, however, continue to be covered by the regulations governing CE Marks (a CE Mark or a CE Mark and UKNI Mark will be required to 
place products on the Northern Ireland market). The EU legal framework, including the IVDR, remains applicable in Northern Ireland (any products placed on 
the market in the Northern Ireland must be compliant with EU law). However, all medical devices and IVDs must be registered with the MHRA, in order to be 
placed on the G.B. market.

The U.K. Government has introduced legislation permitting EU CE Marks to continue to be recognized in G.B. for medical devices. The duration of 
such recognition depends on the EU regulatory framework on the basis of which the medical devices were previously CE marked. The risk classification of 
the devices also has an impact if they were CE marked in accordance with the IVDD. The U.K. government also intends to introduce legislation establishing 
reinforced  post-market  surveillance  requirements  in  early  2024.  The  World  Trade  Organization  ("WTO")  published  notification  of  the  draft  Post-market 
Surveillance Requirements Statutory Instrument (PMS SI) on July 26, 2023. These post-market surveillance requirements are anticipated to apply from mid-
2024. The U.K. government is aiming to have core aspects of the future regulatory regime for medical devices applicable from July 1, 2025. The nature of 
any new regulation in the U.K. is uncertain, and as such, we may experience delays in obtaining future access to the U.K. and other European markets. The 
U.K.’s departure from the EU has also impacted customs regulations and impacted timing and ease of shipments into the EU from the U.K.

The  UK  government  has  recently  amended  the  MDR  2002  to  extend  the  recognition  of  CE  marked  medical  devices  in  Great  Britain.  The 
amendments provide that CE marks will cease to be recognized in Great Britain on June 30, 2030, at the latest. Shorter deadlines may apply depending on 
the regulatory framework on the basis of which the CE mark is affixed and the classification of the medical devices. In addition, CE marks may cease to have 
affect before the deadlines established in the amended UK MDR – if CE Certificates of Conformity expire, or if related application of European Union law 
renders the CE Certificates of Conformity invalid at an earlier date. Accordingly, IVDs CE marked in accordance with the IVDD can be placed on the Great 
Britain market until May 26, 2025 if they are list A, list B, or self-testing IVDs or until June 30, 2030 if they are General IVDs which were self-assessed under 
the  IVDD,  for  which  the  EU  Declaration  of  Conformity  was  issued  in  accordance  with  the  IVDD  prior  to  May  26,  2022,  and  for  which  the  conformity 
assessment under Regulation 217/746 on IVDs (IVDR) will require the involvement of a notified body. IVDs CE marked in accordance with the IVDR can be 
placed on the Great Britain market until June 30, 2030.

Should the U.K. or G.B. further diverge from the EU from a regulatory perspective, tariffs could be put into place in the future. We could therefore, 
both now and in the future, face significant additional expenses 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 EU and the U.K. It is also possible that Brexit may negatively affect our ability to attract 
and retain employees in the U.K., particularly those from the EU.

Our business could be negatively impacted by environmental, social and corporate governance (ESG) matters or our reporting of such 
matters.

There is an increasing focus from certain investors, employees, partners, and other stakeholders concerning ESG matters. We currently do not 
report  our  environmental  emissions  and  absent  a  legal  requirement  to  do  so  we  currently  do  not  plan  to  report  our  environmental  emissions,  and  lack  of 
reporting could result in certain investors declining to invest in our common stock. As ESG best practices and reporting standards continue to develop, we 
may incur increasing costs relating to ESG monitoring and reporting and complying with ESG initiatives. For example, California recently enacted Assembly 
Bill 1305 (“AB 1305”). AB 1305, which became effective on January 1, 2024, creates new annual disclosure requirements regarding substantiation of certain 
climate-related statements, and, if we report climate related statements in the future, could increase our compliance and reporting costs. Additionally, the 
SEC has recently proposed, and may continue to propose, certain mandated ESG reporting requirements, such as the SEC's proposed rules designed to 
enhance and standardize climate-related disclosures, which, if finally approved, would significantly increase our compliance and reporting costs. AB 1305 
and the proposed SEC rules may also result in disclosures that certain investors or other stakeholders deem to negatively impact our reputation and/or that 
harm our stock price. In the event that we communicate certain initiatives or goals regarding ESG matters in the future, we could fail, or be perceived to fail, 
in  our  achievement  of  such  initiatives  or  goals,  or  we  could  be  criticized  for  the  scope  of  such  initiatives  or  goals.  If  we  fail  to  satisfy  the  expectations  of 
certain investors and other stakeholders or our initiatives are not executed as planned, our business, financial condition, results of operations, and prospects 
may be adversely affected.

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 the infringement, misappropriation, or other violation of 
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 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 

39

Table of Contents

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, services 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,  customers,  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 services or products in 
the future.

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

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

Developments  or  uncertainty  in  the  patent  statute,  patent  case  law,  or  U.S.  Patent  and  Trademark  Office  (“USPTO”),  rules  and 
regulations may impact the validity, scope or enforceability of our patent rights, thereby impairing our ability to protect our services and 
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 a 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 diagnostic 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 defend or 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  or  services.  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 2042. 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 services or 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, services 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 choose not to, or 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, services, or products 
in a non-infringing manner.

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, services, 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, services, 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;

41

Table of Contents

•

•

•

•

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 or services 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,  services,  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.

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  have  participated,  are  participating  and  may  in  the  future  have  to  participate,  in  interference  proceedings, 
derivation  proceedings,  inter  partes  review  proceedings,  or  other  post-grant  proceedings  declared  by  the  USPTO  or  a  foreign  patent  office  that  have 
resulted, and could in the future 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 are involved in legal proceedings to defend and enforce our intellectual property rights and may in the future become involved in 
other  lawsuits  to  protect  or  enforce  our  patents  or  other  intellectual  property,  which  could  be  expensive,  time  consuming,  and 
unsuccessful.

Our  intellectual  property  rights  involve  complex  factual,  scientific  and  legal  questions.  We  operate  in  an  industry  characterized  by  significant 
intellectual property litigation. Even though we may believe that we have a valid patent on a particular technology, others may infringe our patents or the 
patents of our licensing partners. For example, we have filed complaints in the U.S. District Court for the District of Colorado against Foresight for patent 
infringement  (see  the  section  titled  “Contingencies”  in  Note  9  to  our  unaudited  condensed  consolidated  financial  statements).  Further,  Foresight  has  filed 
inter partes review petitions with the USPTO in an effort to invalidate five of the seven patents that we are asserting against Foresight, and has alleged that it 
will file additional inter partes review petitions with the USPTO in an effort to invalidate the two other patents that we are asserting against Foresight. The 
USPTO has issued decisions granting inter partes reviews of four of the patents we are asserting against Foresight; the USPTO has yet to issue a decision 
regarding whether it will institute an inter partes review of the fifth patent. In addition, our patents or the patents of our licensors may become 

42

Table of Contents

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 services or 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  services  or  product  or  the  services  or 
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 have caused and may continue to 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.

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 

43

Table of Contents

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 sought or obtained patent protection to develop their own products and services 
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 services and products may compete with our services and 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  have  chosen  and  in  the  future  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 defend or 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.

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 has resulted or 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, 

44

Table of Contents

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, services 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, services or technologies 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 technologies 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  or  provision  of  our  services.  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 and services 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.

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 may seek to raise additional capital through equity offerings, debt financings, collaborations, or licensing arrangements to continue executing 

on our long-term business plan. Additional funding may not be available to us on acceptable terms, or at all.

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

If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of or eliminate one or more research and 
development  programs  or  sales  and  marketing  initiatives.  Our  ability  to  raise  additional  capital  may  be  adversely  impacted  by  potential  worsening  global 
economic conditions and the recent disruption to and volatility in the credit and financial markets in the U.S. and worldwide resulting from macroeconomic 
conditions, actual or perceived changes in interest rates and inflation, geopolitical conflicts (including the Russia-Ukraine war, the state of war between Israel 
and  Hamas  and  the  risk  of  a  larger  regional  conflict).  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  relating  to  significant  acquisitions,  strategic  partnerships,  joint  ventures,  collaborations,  capital 
commitments, or by or pertaining to our customers, particularly the VA MVP and Natera, as our largest customers;

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

46

Table of Contents

•

•

•

•

•

•

•

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;

health  epidemics  or  pandemics,  geopolitical  conflicts,  inflation,  global  supply  chain  issues,  regional  or  national  economic  slowdowns, 
recessions, depressions or other economic downturns; and

other  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 in connection with the COVID-19 
pandemic, global supply chain challenges, inflation and fears of economic recession, which have 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.

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, 
Natera 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.

Unstable market, economic and geo-political conditions may have serious adverse consequences on our business, financial condition 
and stock price.

The global credit and financial markets have experienced extreme volatility and disruptions in the past. These disruptions can result in severely 
diminished liquidity and credit availability, increases in inflation, declines in consumer confidence, declines in economic growth, increases in unemployment 
rates  and  uncertainty  about  economic  stability.  There  can  be  no  assurance  that  further  deterioration  in  credit  and  financial  markets  and  confidence  in 
economic  conditions  will  not  occur,  including  actual  or  perceived  changes  in  interest  rates  and  inflation.  Our  general  business  strategy  may  be  adversely 
affected by any such economic downturn, volatile business environment, higher inflation, or continued unpredictable and unstable market conditions. If the 
current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive. Our portfolio 
of corporate and government bonds could also be adversely impacted. Failure to secure any necessary financing in a timely manner and on favorable terms 
could have a material adverse effect on our operations, growth strategy, financial performance and stock price and could require us to delay or abandon 
development or commercial initiatives. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not 
survive an economic downturn or rising inflation, which could directly affect our ability to attain our operating goals on schedule and on budget.

Other international and geo-political events could also have a serious adverse impact on our business. For instance, in February 2022, Russia 
initiated military action against Ukraine and the two countries are now at war. In addition, in October 2023, Hamas attacked Israel which provoked a state of 
war, and there is a risk of a larger conflict. In response, the United States and certain other countries imposed significant sanctions and trade actions against 
Russia and could impose further sanctions, trade restrictions, and other retaliatory 

47

Table of Contents

actions.  While  we  cannot  predict  the  broader  consequences,  the  conflict  and  retaliatory  and  counter-retaliatory  actions  could  continue  to  affect,  and 
potentially  materially  adversely  affect,  global  trade,  currency  exchange  rates,  inflation,  regional  economies,  and  the  global  economy,  which  in  turn  may 
increase our costs, disrupt our supply chain, impair our ability to raise or access additional capital when needed on acceptable terms, if at all, or otherwise 
adversely affect our business, financial condition, and results of operations.

Adverse  developments affecting the financial  services  industry  could  adversely  affect  our  current  and  projected  business  operations 
and our financial condition and results of operations.

Adverse developments that affect financial institutions, such as events involving liquidity that are rumored or actual, have in the past and may in 
the  future  lead  to  bank  failures  and  market-wide  liquidity  problems.  For  example,  on  March  10,  2023,  Silicon  Valley  Bank  (“SVB”)  was  closed  by  the 
California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation (“FDIC”) as receiver. Similarly, on 
March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership. In addition, on May 1, 2023, the FDIC seized First Republic 
Bank and sold its assets to JPMorgan Chase & Co.

Although  we  assess  our  banking  relationships  as  we  believe  necessary  or  appropriate,  our  access  to  cash  in  amounts  adequate  to  finance  or 
capitalize our current and projected future business operations could be significantly impaired by factors that affect the financial institutions with which we 
have  banking  relationships.  These  factors  could  include,  among  others,  events  such  as  liquidity  constraints  or  failures,  the  ability  to  perform  obligations 
under various types of financial, credit or liquidity agreements or arrangements, disruptions or instability in the financial services industry or financial markets, 
or concerns or negative expectations about the prospects for companies in the financial services industry. These factors could also include factors involving 
financial  markets  or  the  financial  services  industry  generally.  The  results  of  events  or  concerns  that  involve  one  or  more  of  these  factors  could  include  a 
variety of material and adverse impacts on our current and projected business operations and our financial condition and results of operations. These could 
include,  but  may  not  be  limited  to,  delayed  access  to  deposits  or  other  financial  assets  or  the  uninsured  loss  of  deposits  or  other  financial  assets;  or 
termination of cash management arrangements and/or delays in accessing or actual loss of funds subject to cash management arrangements.

In addition, widespread investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing 
terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, 
thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any decline in available funding or access to our cash and liquidity 
resources could, among other risks, adversely impact our ability to meet our operating expenses, financial obligations or fulfill our other obligations, result in 
breaches  of  our  financial  and/or  contractual  obligations  or  result  in  violations  of  federal  or  state  wage  and  hour  laws.  Any  of  these  impacts,  or  any  other 
impacts  resulting  from  the  factors  described  above  or  other  related  or  similar  factors  not  described  above,  could  have  material  adverse  impacts  on  our 
liquidity and our current and/or projected business operations and financial condition and results of operations.

We maintain our cash at financial institutions, often in balances that exceed federally insured limits.

We  maintain  the  majority  of  our  cash  and  cash  equivalents  in  accounts  at  banking  institutions  in  the  United  States  that  we  believe  are  of  high 
quality. Cash held in these accounts often exceed the FDIC insurance limits. If such banking institutions were to fail, we could lose all or a portion of amounts 
held in excess of such insurance limitations. As noted above, the FDIC took control of SVB, Signature Bank, Silvergate Capital Corp and First Republic Bank 
in the first half of 2023. While we did have an account at SVB, we were able to recover all of our deposits when the FDIC stepped in and allowed us to 
transfer funds held at SVB to another bank without incurring any losses. In the event of failure of any of the financial institutions where we maintain our cash 
and cash equivalents, there can be no assurance that we would be able to access uninsured funds in a timely manner or at all. Any inability to access or 
delay in accessing these funds could adversely affect our business and financial position.

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, 2023, we had 50,480,694 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, 2023 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 

48

Table of Contents

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 
and under our at-the-market facility, 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, 2023, we had federal and state net operating loss carryforwards of approximately $285.5 million and approximately $274.7 
million,  respectively.  Certain  of  our  federal  and  state  net  operating  loss  carryforwards  will  begin  to  expire,  if  not  utilized,  beginning  in  2031.  These  net 
operating loss carryforwards could expire unused and be unavailable to offset future 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 thereafter 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.

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.

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.

Table of Contents

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 in the event we no longer qualify as 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.

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

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

We  are  a  smaller  reporting  company,  and  any  decision  on  our  part  to  avail  ourselves  of  certain  reduced  reporting  and  disclosure 
requirements applicable to smaller reporting companies could make our common stock less attractive to investors.

We  are  a  “smaller  reporting  company”  as  defined  in  the  Exchange  Act.  We  intend  to  take  advantage  of  exemptions  from  various  reporting 

requirements applicable to other public companies that are not smaller reporting companies, including scaled disclosure on executive compensation. 

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. 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.

Effective  internal  control  over  financial  reporting  is  necessary  for  us  to  provide  reliable  financial  reports  and,  together  with  adequate  disclosure 
controls  and  procedures,  are  designed  to  prevent  fraud.  Any  failure  to  implement  required  new  or  improved  controls,  or  difficulties  encountered  in  their 
implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404(a) of the 
Sarbanes-Oxley  Act,  or  any  testing  by  our  independent  registered  public  accounting  firm,  may  reveal  deficiencies  in  our  internal  control  over  financial 
reporting  that  are  deemed  to  be  material  weaknesses  or  that  may  require  prospective  or  retroactive  changes  to  our  financial  statements  or  identify  other 
areas  for  further  attention  or  improvement.  Inferior  internal  control  over  financial  reporting  could  also  cause  investors  to  lose  confidence  in  our  reported 
financial information, which could have a negative effect on the trading price of our common stock. 

We  are  a  non-accelerated  filer.  For  so  long  as  we  remain  a  non-accelerated  filer,  our  independent  registered  public  accounting  firm  will  not  be 
required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act. An independent 
assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting  could  detect  problems  that  our  management’s  assessment  might  not. 
Undetected material weaknesses in our internal control over financial reporting could lead to financial statement restatements and require us to incur the 
expense of remediation.

Item 1C. Cybersecurity

Risk Management and Strategy

We  have  implemented  and  maintain  various  information  security  processes  designed  to  identify,  assess  and  manage  material  risks  from 
cybersecurity threats to our critical computer networks, third party hosted services, communications systems, hardware and software, and our critical data, 
including  intellectual  property,  confidential  information  that  is  proprietary,  strategic  or  competitive  in  nature,  personal  information,  and  Personal  Health 
Information (“PHI”) (collectively, “Information Systems and Data”).

The board of director’s audit committee and the internal cybersecurity team help identify, assess and manage the Company’s cybersecurity threats 
and  risks,  including  through  the  use  of  our  risk  register.  Our  internal  cybersecurity  team  includes  our  information  security  function,  security  management, 
engineering operations, legal, risk management and third-party service providers. Our cybersecurity team identifies and assesses risks from cybersecurity 
threats  by  monitoring  and  evaluating  our  threat  environment  and  Personalis’  risk  profile  using  various  methods  including,  for  example:  using  manual  and 
automated  tools,  conducting  scans  of  the  threat  environment,  evaluating  our  and  our  industry’s  risk  profile,  evaluating  threats  reported  to  us,  conducting 
threat assessments, employee reporting, and regular reviews and internal and external audits.

Depending on the environment, we implement and maintain various technical, physical, and organizational measures, processes, standards and 
policies  designed  to  manage  and  mitigate  material  risks  from  cybersecurity  threats  to  our  Information  Systems  and  Data,  including,  for  example:  incident 
response  plan,  incident  detection  and  response,  disaster  recovery  and  business  continuity  plans,  risk  assessments,  network  security  controls,  access 
controls, user management, asset management, hardware and data segregation, system monitoring and regular reviews.

Our  assessment  and  management  of  material  risks  from  cybersecurity  threats  are  integrated  into  our  overall  risk  management  processes.  For 
example,  cybersecurity  risk  is  addressed  as  a  component  of  our  enterprise  risk  management  program  and  identified  in  our  risk  register.  Additionally,  the 
cybersecurity team monitors activity on a continual basis and works with security management to prioritize our risk profile and mitigate cybersecurity threats 
that  are  more  likely  to  lead  to  a  material  impact  to  our  business  on  a  monthly  basis;  executive  management  evaluates  material  risks  from  cybersecurity 
threats against our overall business objectives on a periodic basis and reports to the audit committee of the board of directors, which evaluates our overall 
enterprise risk periodically.

We  use  third-party  service  providers  to  assist  us  from  time  to  time  to  identify,  assess,  and  manage  material  risks  from  cybersecurity  threats, 

including for example cybersecurity consultants, threat intelligence service providers, and professional services firms.

We use third-party service providers to perform a variety of functions throughout our business, including, but not limited to infrastructure support 
and maintenance, supply chain resources, contracting services and software integrations. These vendors are reviewed as part of our vendor management 
program, including the management of cybersecurity risks associated with our use of these providers. Depending on the nature of the services provided, the 
sensitivity of the Information Systems and Data at issue, and the identity of the provider, our vendor management process may involve different levels of 
assessment  designed  to  help  identify  cybersecurity  risks  associated  with  a  provider  and  impose  contractual  obligations  related  to  cybersecurity  on  the 
provider.

For  a  description  of  the  risks  from  cybersecurity  threats  that  may  materially  affect  the  Company  and  how  they  may  do  so,  see  our  risk  factors 
under Part I, Item1A. Risk Factors in this Annual Report on Form 10-K, including “If our information technology systems or data, or those of third parties 
upon  which  we  rely,  are  or  were  compromised,  we  could  experience  adverse  consequences  resulting  from  such  compromise,  including  but  not  limited  to 
regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of 
customers or sales; and other adverse consequences.”

Governance

Our  board  of  directors  addresses  our  cybersecurity  risk  management  as  part  of  its  general  oversight  function.  The  board  of  directors’  audit 

committee is responsible for overseeing the Company’s cybersecurity risk management processes.

Our  cybersecurity  risk  assessment  and  management  processes  are  implemented  and  maintained  by  certain  of  our  management,  including  the 
Vice President of Informatics, who has more than 20 years of experience in information technology and oversees the Informatics department which includes 
the Company’s hardware, software, help desk, and cybersecurity team.

The  Vice  President  of  Informatics  reports  to  our  Chief  Financial  Officer  and  is  responsible  for  hiring  appropriate  personnel,  helping  to  integrate 
cybersecurity risk considerations into our overall risk management strategy, and communicating key priorities to relevant personnel. The Vice President of 
Informatics  is  responsible  for  approving  budgets,  helping  prepare  for  cybersecurity  incidents,  approving  cybersecurity  processes,  and  reviewing  security 
assessments and other security-related reports.

Our  cybersecurity  incident  response  and  vulnerability  management  processes  are  designed  to  escalate  certain  cybersecurity  incidents  to 

members of management depending on the circumstances, including the internal cybersecurity team and others, depending 

53

Table of Contents

on severity. The cybersecurity team works with our incident response team to help the company mitigate and remediate cybersecurity incidents of which they 
are notified. In addition, our incident response processes include reporting to the audit committee of the board of directors for certain cybersecurity incidents.

The  board  of  directors  receives  periodic  updates  from  certain  members  of  the  cybersecurity  team  concerning  the  Company’s  significant 
cybersecurity  threats  and  risk  and  the  processes  we  have  implemented  to  address  them.  The  audit  committee  and  board  also  have  access  to  various 
reports, summaries or presentations related to cybersecurity threats, risk and mitigation.

Item 2. Properties.

Our  corporate  headquarters  is  located  in  Fremont,  California,  and  comprise  100,000  square  feet  of  space,  pursuant  to  a  lease  that  expires  in 
2036. The lease includes two options to extend the term for a period of five-years per option, at prevailing market rates. This facility is used for our CLIA-
certified and CAP-accredited laboratory operations, research and development, and corporate functions.

We also lease 31,280 square feet of space in Menlo Park, California, pursuant to a lease that expires in 2027. This facility was previously used for 

laboratory operations and our former corporate headquarters. We are actively marketing the space for sublease.

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.

results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and elsewhere in 
this Annual Report on Form 10-K.

Overview

We  develop  and  market  advanced  cancer  genomic  tests  and  analytics.  Our  tests  and  analytics  are  used  by  pharmaceutical  companies  for 
translational research, biomarker discovery, the development of personalized cancer therapies, and we expect in the near future, for clinical trial enrollment. 
Our  advanced  tests  are  used  by  physicians  to  detect  cancer  recurrence,  monitor  cancer  evolution,  and  uncover  insights  for  therapy  selection.  We  also 
provide sequencing and data analysis services to support population sequencing initiatives.

Today, our products are routinely used by many of the largest oncology-focused pharmaceutical companies for analysis of patient samples in their 
clinical  trials  and  drug  development  programs.  Our  advanced  genomic  sequencing  and  analytics  also  support  the  development  of  personalized  cancer 
vaccines  and  other  next-generation  cancer  immunotherapies.  For  example,  we  are  providing  genomic  testing  to  Moderna,  Inc.  ("Moderna")  in  its  ongoing 
clinical trials evaluating a personalized cancer vaccine. In addition, we partner with diagnostics companies by providing our advanced tumor profiling and 
analysis  capabilities  as  an  input  to  their  products.  More  recently,  we  launched  new  diagnostic  offerings  for  the  clinical  setting  and,  in  November  2023, 
entered into an agreement with Tempus AI, Inc. (formerly known as Tempus Labs, Inc., and referred to herein as "Tempus") to commercialize NeXT Personal 
Dx in the clinical diagnostics market. Finally, we have also pursued non-cancer related business opportunities, specifically within the population sequencing 
market, by providing whole genome sequencing ("WGS") services under contract with the U.S. Department of Veterans Affairs Million Veteran Program ("VA 
MVP").

As  part  of  one  of  our  new  strategies  for  2023  and  beyond,  we  are  working  with  a  growing  number  of  leading  cancer  centers  and  world-class 
academic  research  institutions  to  build  and  publish  the  clinical  evidence-base  to  support  our  products  and  our  key  indications,  as  well  as  to  obtain 
reimbursement coverage from Medicare and other payors. Because of the ultra-high analytical sensitivity of our technology, we are initially focusing on three 
indications: breast cancer, lung cancer, and immunotherapy (IO) monitoring. We have collaborations with Cancer Research UK, University College London, 
and the Francis Crick Institute (the TRACERx study); The Royal Marsden; the Vall d'Hebron Institute of Oncology (VHIO); Duke University; the Dana-Farber 
Cancer Institute; University Medical Center Hamburg-Eppendorf (also known as UKE); and Criterium and the Academic Breast Cancer Consortium that will
focus on building the evidence-base for our technology and these indications. If the key opinion leaders ("KOLs") we are collaborating with have a positive 
experience using our products, we are optimistic this will support broader use of our products by other KOLs, as well as clinicians in the future.

Our work in oncology is underpinned by our experience and capacity for next-generation sequencing at scale. We have the capacity to sequence 
and analyze over 300 trillion bases of DNA per week in our facility. We believe that our capacity is already larger than most cancer genomics companies, and 
we  continue  to  build  automation  and  other  infrastructure  to  scale  further  as  demand  increases.  To  date,  we  have  sequenced  more  than  385,000  human 
samples, of which more than 175,000 were whole human genomes.

2023 Highlights

Total revenue increased 13%, or $8.4 million, during 2023 compared to 2022, primarily driven by higher revenue from enterprise sales and pharma 
tests. Revenue from enterprise sales was $31.7 million in 2023 compared to $26.6 million in 2022, an increase of 19%. Revenue from pharma tests was 
$31.9 million in 2023 compared to $29.6 million in 2022, an increase of 8%.

Key business accomplishments and financial updates in 2023 and early 2024 include:

•

•

•

•

•

•

•

•

Table of Contents

Factors Affecting Our Performance

We believe there are several important factors that we expect 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  pharmaceutical 
companies,  enterprise  customers,  and  oncologists  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  products  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 products. 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 products.

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. We are also collaborating with KOLs to support the clinical utility of our products. We 
believe this work is critical to gaining customer adoption and expect our investments in these efforts to continue.

Leverage  our  operational  infrastructure.  We  have  invested  significantly  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 products. We expect to grow our revenue and spread our costs over a larger volume of services.

Components of Operating Results

Revenue

We derive our revenue from sales of advanced sequencing and analytics to the following four customer types:

•

•

•

•

Pharma tests and services includes sales of testing services and data analytics for clinical trials and research to pharmaceutical companies 
in support of their drug development programs.

Enterprise sales includes sales of tumor profiling and diagnostic tests directly to another business as an input to their products. Revenue 
from our partnership with Natera to provide advanced tumor analysis for use in Natera's MRD test currently makes up substantially all of the 
revenue in this category.

Population  sequencing  includes  sales  of  genomic  sequencing  services  and  data  analytics  to  support  large-scale  genetic  research 
programs. All of the revenue in this category is from our partnership with the VA MVP.

Other  includes  sales  of  genomic  tests  and  analytics  to  universities  and  non-profits.  This  category  also  includes  sales  of  diagnostics  tests 
ordered by healthcare providers for cancer patients, which was insignificant for periods presented.

Our ability to increase revenue will depend on our ability to further increase sales to these groups of customers, expand our customer base within 
each group, and expand our business in the clinical diagnostics market. To do this, we are developing a growing set of state-of-the-art services and products; 
advancing our operational infrastructure; building our regulatory credentials; focusing our marketing efforts on large pharmaceutical companies; building and 
publishing the clinical evidence-base to support our products and our key indications, as well as to obtain reimbursement coverage from Medicare and other 
payors; and seeking additional partnerships such 

57

Table of Contents

as ours with Natera. We sell through a small direct sales force. In late 2023, we entered into an agreement with Tempus to commercialize NeXT Personal Dx 
in the clinical diagnostics market and will be leveraging Tempus' significantly larger sales force.

We  have  one  reportable  segment  from  the  sale  of  sequencing  and  data  analysis  services.  Most  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 variability in our gross margins over the medium-term due to fluctuations in customer mix and volume, investments in newer sequencing platforms 
and  new  capabilities  such  as  automation  of  laboratory  workflows,  processing  of  diagnostic  tests  for  the  clinical  market  while  we  work  to  secure 
reimbursement,  and  costs  related  to  our  new  Fremont  facility.  Over  the  long-term,  we  anticipate  higher  gross  margins  as  growing  revenue  leads  to 
economies of scale.

Research and Development Expenses

Research and development expenses consist of costs incurred for the research and development of our services and products and costs related 
to  conducting  studies  and  collaborations  with  partners  to  validate  the  clinical  utility  of  our  offerings.  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, 
product development, collaborations and studies; 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.

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

decrease as a result of our reductions in workforce initiated in 2023 and our closure of operations in China.

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.

Selling, general and administrative expenses have decreased significantly since the completion of our first quarter 2023 reduction in workforce. 

We expect expenses to remain around this lower level over the next couple of years.

Lease Impairment

We recognized an impairment loss for operating lease right-of-use assets as a result of the change in use of our Menlo Park facility during the 

third quarter of 2023.

Restructuring and Other Charges

Restructuring and other charges consists of charges in connection with our two reductions in workforce initiated in 2023 and charges in connection 

with the closure of our China operations.

Interest Income and Interest Expense

Interest  income  consists  primarily  of  interest  earned  on  our  cash  and  cash  equivalents  and  short-term  investments.  Interest  expense  is  the 

recognition of imputed interest on noninterest bearing loans.

Other Income (Expense), Net

Other  income  (expense),  net  consists  primarily  of  charges  related  to  the  issuance  and  remeasurement  of  warrants  to  Tempus  during  the  year 

ended December 31, 2023. Otherwise, other income (expense), net consists primarily of foreign currency exchange gains and losses.

Revenue  from  pharma  tests  and  services  increased  8%,  or  $2.4  million,  in  2023.  Growth  from  new  customers  drove  the  revenue  increase. 
Notably,  three  customers  that  were  either  new  in  2023  or  2022,  accounted  for  an  increase  of  $3.8  million  in  revenue  as  these  customers  selected  our 
advanced  genomic  tests  for  their  clinical  trials  and  research  projects.  Additionally,  revenue  from  one  of  our  customers  developing  personalized  cancer 
therapies increased by $2.3 million. Those increases were partially offset by decreases in revenue from multiple customers due to non-recurring projects and 
variability in timing and spending levels on clinical trial projects in general.

Enterprise sales

Revenue  from  enterprise  sales  increased  19%,  or  $5.1  million,  in  2023.  This  was  due  to  an  increase  in  the  volume  of  samples  we  tested  for 

Natera, partially offset by lower selling prices. The number of samples we processed for Natera increased by over 55% in 2023.

We  amended  our  agreement  with  Natera  during  the  fourth  quarter  of  2023  to  extend  minimum  volume  commitments  through  the  end  of  2024. 
Previously, Natera's volume commitments extended only through the first quarter of 2024. In addition, we plan to introduce a lower-cost version of our exome 
product  offering  for  Natera  in  the  first  half  of  2024  in  order  to  support  their  price  requirements,  and  we  expect  our  total  revenue  from  Natera  in  2024  to 
decline, due to the lower prices.

Population sequencing

Population sequencing revenue is made up entirely of sales to the VA MVP. The increase in revenue was driven by an increase in samples we 

tested, which offset a nearly 50% reduction in selling prices in 2023 as compared to 2022.

Revenue recognized each period is also impacted by timing of our fulfillment of samples under each annual task order. Our annual task orders 
received in 2023, 2022, and 2021 were $7.5 million, $10.0 million, and $9.7 million, respectively. 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 from the VA MVP up or down to complement sample 
volumes from other customers, which can vary from period to period. As of the end of 2023, our remaining unfulfilled task orders amounted to $7.4 million, 
which we expect to recognize as revenue within the next 12 months.

The increase in cost of revenue of 7%, or $3.6 million, was primarily due to higher revenue levels (revenue increased 13% over the same period), 
partially offset by dedication of more laboratory resources to support sample processing required for clinical evidence generation, which is a non-revenue 
generating  activity  and  thus  reported  as  R&D  expense.  Specific  components  of  the  increase  were  a  $4.9  million  increase  in  direct  material  costs  due  to 
higher revenue levels, a $2.0 million increase in facilities and equipment costs (partly due to movement of our laboratory from our prior Menlo Park facility to 
the new Fremont facility), and a $2.0 million increase in laboratory supplies and consumables (enterprise customer orders require more supplies to process 
as  compared  to  other  customer  categories);  partially  offset  by  a  $5.3  million  decrease  in  shared  laboratory  costs  due  to  greater  usage  of  our  laboratory 
capacity for R&D activities.

Research and development

Research and development expenses remained flat in 2023 as compared to 2022. Increases in costs associated with clinical evidence generation 
and collaborations, and increases in facility costs (as a result of the R&D function moving into our Fremont facility during 2023), were offset by cost savings 
from our reductions in workforce initiated in 2023.

Specific offsetting components of research and development expense include a $5.0 million increase in sample processing costs incurred in our
laboratory for product development, collaborations, and clinical evidence generation, and a $2.2 million increase in facilities costs; offset by a $7.3 million 
decrease in personnel-related costs driven by our reductions in workforce.

Selling, general and administrative

The decrease in selling, general and administrative expenses of 22%, or $14.2 million was primarily due to cost savings from our reductions in 

workforce initiated in 2023.

Specific components of the decrease were a $11.7 million decrease in personnel-related costs driven by our reductions in workforce, a $5.1 million 
decrease in facilities costs as a result of the R&D function and additional lab teams moving into our Fremont facility and consequently receiving a share of 
such facility costs that were previously allocated to SG&A, and a $1.5 million decrease in professional services; partially offset by a $2.9 million increase in 
depreciation of office-related fixtures and furniture (driven by our Fremont headquarters), a $1.0 million increase in software and subscriptions costs, and a 
$0.2 million increase in marketing costs such as trade shows expenses.

Lease impairment

During  the  third  quarter  of  2023,  we  completed  the  move  of  our  laboratory  operations  from  our  Menlo  Park  facility  to  our  Fremont  facility  and 
began  actively  marketing  the  Menlo  Park  space  for  sublease.  Accordingly,  we  evaluated  the  ongoing  value  of  the  operating  lease  right-of-use  asset 
associated with the Menlo Park facility. Based on this evaluation, we determined that the right-of-use asset with a carrying amount of $6.7 million was no 
longer recoverable and was impaired and wrote it down to its estimated fair value of $1.1 million, which resulted in a noncash impairment loss of $5.6 million. 
Estimated  fair  value  was  based  on  expected  future  sublease  cash  flows  (with  the  assistance  of  a  third-party  real  estate  broker),  net  of  brokerage 
commissions and estimated tenant incentives, discounted at a market rate of return on similar assets. The estimation of fair value also included expected 
downtime prior to the commencement of a future sublease.

Restructuring and other charges

During  2023,  we  initiated  two  rounds  of  workforce  reductions  to  reduce  our  cash  burn  and  increase  operating  efficiencies.  Combined,  our 

headcount was reduced by almost 50% from 2022 levels. We also closed our China operations.

The  $8.1  million  in  restructuring  and  other  charges  recognized  in  2023  is  comprised  of  $7.5  million  in  one-time  employee  termination  benefits 
(including costs related to termination of our former China employees) and $0.6 million of other noncash charges (primarily asset disposals and impairments 
in connection with the closure of our China operations).

The  increase  in  interest  income  was  due  to  increased  yields  on  our  investments.  Interest  expense  is  the  recognition  of  imputed  interest  on 

noninterest bearing loans.

Other income (expense), net

In connection with our November 2023 agreement with Tempus, we issued two warrants to purchase, in the aggregate, up to 9,218,800 shares of 
our common stock. If Tempus acquires any shares of common stock directly from us other than by exercising the warrants, then the total number of shares 
issuable upon exercise of the warrants will be reduced by such shares. Because the number of shares issuable upon settlement are subject to adjustment, 
the warrants are classified as liability instruments and are subject to remeasurement at each balance sheet date, with changes in fair value recognized as 
other  income  (expense).  Additionally,  since  the  initial  fair  value  of  the  warrants  of  $6.9  million  exceeded  the  total  proceeds  received  from  Tempus  of  $6 
million, a loss of $0.9 million was immediately recognized within other income (expense).

Fair value of the warrants increased by $3.1 million as of December 31, 2023. The increase in fair value, plus the immediate loss of $0.9 million 

recognized upon issuance, resulted in a $4.0 million expense recognized in other income (expense), net during the year ended December 31, 2023.

During 2022 and 2021, other income (expense), net consisted mainly of foreign currency remeasurements.

From our inception through December 31, 2023, 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, $89.6 million from issuance of redeemable 
convertible preferred stock, $3.5 million in net proceeds from our ATM facility (see Note 2, Summary of Significant Accounting Policies), as well as cash from 
operations and debt financings. As of December 31, 2023, we had cash and cash equivalents of $57.0 million and short-term investments of $57.2 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  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,  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  sales  agreement  prospectus  in  December  2023  pursuant  to  which  we  may  offer  and  sell  up  to  $50.0  million  of  shares  of  our 
common  stock  through  our  ATM  facility.  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,  2023,  cash  and  cash  equivalents  held  by  foreign  subsidiaries  was  $1.2  million,  most  of  which  was  held  by  our  China 
subsidiary.  During  the  first  half  of  2023,  we  closed  our  China  operations  and,  in  February  2024,  we  completed  the  dissolution  of  the  China  entity  and 
repatriated all cash that was held at the entity back to our headquarters.

The $14.0 million decrease in cash used in operating activities during 2023 as compared to 2022 was primarily due to lower spend on operating 
expenses (particularly lower payroll expenses after our reductions in workforce initiated in 2023), higher customer deposits received (mostly in connection 
with  our  agreement  with  Moderna  to  support  its  ongoing  clinical  trials  evaluating  a  personalized  cancer  vaccine),  and  efficient  management  of  working 
capital; partially offset by lower landlord contributions received during 2023 versus 2022 in connection with our Fremont facility build-out.

The $39.4 million decrease in cash provided by investing activities during 2023 as compared to 2022 was due to significantly lower net proceeds 

from short-term investment maturities, partially offset by a $39.0 million reduction in capital expenditures.

The  $9.7  million  increase  in  cash  provided  by  financing  activities  during  2023  as  compared  to  2022  was  driven  by  $6  million  in  proceeds  from 
issuance of warrants to Tempus and $3.5 million in net proceeds from sales of common stock under our ATM facility, both of which did not occur during 2022.

Material Cash Requirements

Our  material  cash  requirements  in  the  short-  and  long-term  consist  primarily  of  variable  costs  of  revenue,  operating  expenditures,  capital 
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 $114.2 million as of December 31, 2023, as well as anticipated cash receipts from customers. To fund our material cash 
requirements  in  the  short-  and  long-term,  we  may  also  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.

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. 
We currently expect spending in this area to increase in 2024 relative to 2023 to support expected higher levels of revenue.

Operating expenditures. Our primary use of cash relates to employee compensation, 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 
decrease  our  spend  in  these  areas  as  a  result  of  our  workforce  reductions  initiated  in  2023.  On  a  long-term  basis,  we  manage  future  cash  requirements 
relative to our long-term business plans.

Capital  expenditures.  Capital  expenditures  are  expected  to  decrease  from  2023  levels  as  we  have  completed  significant  laboratory  capacity 
additions. Going forward, our capital expenditures are expected to consist primarily of laboratory equipment and computer equipment. We currently expect 
capital expenditures to be approximately $1 million in 2024 and between $4 million to $6 million in each of the years 2025 and 2026.

Property leases. Our noncancelable operating lease payments were $78.6 million as of December 31, 2023. 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. As of December 31, 2023, we have an outstanding noninterest bearing loan that was used to finance the purchase of equipment for our 
laboratory. We owe a total of $2.5 million, with half of that amount owed in 2024 and the other half in 2025. Additionally, we had an outstanding noninterest 
bearing loan that was used to finance the purchase of internal use software licenses and related ongoing support. We will make a payment of $0.4 million in 
September 2024 to pay off this loan. Further discussion of this loan can be found in Part II, Item 8 of this Form 10-K in the Notes to Consolidated Financial 
Statements in Note 6, “Loans.”

Critical Accounting Policies and Estimates

Our  consolidated  financial  statements  are  prepared  in  accordance  with  U.S.  GAAP.  The  preparation  of  our  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, leases, and common 
stock  warrants  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 or rebates. 

63

Table of Contents

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.

Leases

Lease liabilities are recognized at the present value of the fixed lease payments, reduced by landlord incentives, using a discount rate based on 

our current borrowing rate at the lease commencement date (the incremental borrowing rate), unless the rate implicit in the lease is readily determinable.

In  August  2021,  we  entered  into  a  13.5-year  lease  for  our  new  corporate  headquarters  in  Fremont,  California.  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.

In September 2022, the lease commencement date for our new facility in Fremont, California was delayed from the original intended date due to 
delays  in  the  completion  of  the  work  necessary  for  us  to  move  into  the  facility,  which  resulted  in  a  reassessment  of  the  lease  term  and  consequently  a 
remeasurement  of  the  lease  liability  and  corresponding  adjustment  to  the  carrying  amount  of  the  right-of-use  asset  based  on  an  updated  incremental 
borrowing rate. We estimated our incremental borrowing rate by using the same method described above and concluded that the incremental borrowing rate 
for  the  remeasured  lease  was  10.5%.  The  lease  reassessment  resulted  in  a  $12.9  million  reduction  to  right-of-use  assets  in  2022.  The  increase  in  our 
estimated borrowing rate between August 2021 and September 2022 mostly reflects the higher interest rate environment in 2022 as compared to 2021.

During  the  third  quarter  of  2023,  we  completed  the  move  of  our  laboratory  operations  from  our  Menlo  Park  facility  to  our  Fremont  facility  and 
began  actively  marketing  the  Menlo  Park  space  for  sublease.  Accordingly,  we  evaluated  the  ongoing  value  of  the  operating  lease  right-of-use  asset 
associated with the Menlo Park facility. Based on this evaluation, we determined that the right-of-use asset with a carrying amount of $6.7 million was no 
longer recoverable and was impaired and wrote it down to its estimated fair value of $1.1 million, which resulted in a noncash impairment loss of $5.6 million. 
Estimated  fair  value  was  based  on  expected  future  sublease  cash  flows  (with  the  assistance  of  a  third-party  real  estate  broker),  net  of  brokerage 
commissions and estimated tenant incentives, discounted at a market rate of return on similar assets. The estimation of fair value also included expected 
downtime prior to the commencement of a future sublease.

Common Stock Warrants

In  November  2023,  we  entered  into  an  agreement  with  Tempus  to  commercialize  NeXT  Personal  Dx  in  the  clinical  diagnostics  market.  In 
connection with this agreement, we issued to Tempus two warrants to purchase, in the aggregate, up to 9,218,800 shares of our common stock. If Tempus 
acquires any shares of common stock directly from us other than by exercising the warrants, then the total number of shares issuable upon exercise of the 
warrants will be reduced by such shares. Because the number of shares issuable upon settlement are subject to adjustment, the warrants are classified as 
liability instruments and are subject to remeasurement at each balance sheet date, with changes in fair value recognized as other income (expense).

The Black-Scholes option-pricing model was used to estimate fair value of the warrants issued to Tempus at the date of issuance, November 28, 
2023, and at each subsequent balance sheet date. Estimating fair value using the Black-Scholes option-pricing model requires a number of assumptions. 
Changes  in  the  assumptions  can  materially  affect  the  fair  value  and  ultimately  how  much  other  income  (or  expense)  is  recognized.  The  inputs  generally 
require analysis to develop.

•

Expected Term—The expected term assumption represents the contractual period of each of the two warrants.

Expected Volatility—Expected volatility was based on the Company's actual historical volatility over the expected terms of the warrants.

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 warrants.

Note 1. Company and Nature of Business

PERSONALIS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Personalis,  Inc.  (the  "Company"  or  "Personalis")  develops  and  markets  advanced  genomic  tests  and  analytics  for  precision  oncology  and 
personalized  testing.  The  Company  also  provides  sequencing  and  data  analysis  services  to  support  population  sequencing  initiatives.  Genomic  tests  are 
sold primarily to pharmaceutical companies, biopharmaceutical companies, diagnostics 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.

The Company is expanding its business model to offer genomic tests directly to cancer patients in a clinical setting. However, revenue generated 

from clinical customers was not significant for any periods presented in these consolidated financial statements.

The Company was incorporated in Delaware in February 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.  During  the  first  half  of  2023,  the  Company  terminated  its  operations  in  China  and  the  Company 
completed the process of dissolving the Personalis (Shanghai) Ltd entity in February 2024. Refer to Note 9 for further information. 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  studies  to  prove  the  clinical 
validity and utility of the Company's tests. 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, revenue recognition, useful 
lives assigned to long-lived assets, discount rates for lease accounting, the valuation of stock options, the valuation of common stock warrants, provisions for 
income  taxes,  and  fair  value  of  lease  right-of-use  assets.  Actual  results  could  differ  from  these  estimates,  and  such  differences  could  be  material  to  the 
Company’s consolidated financial position and results of operations.

Follow-On and At-the-Market Equity Offerings

In January 2021, the Company completed a follow-on equity offering in which it issued and sold 4,542,500 shares of its common stock at a public 

offering price of $38.00 per share. The Company received net proceeds of $162.3 million after deducting underwriting discounts and commissions.

In December 2021, the Company entered into an At-the-Market ("ATM") Sales Agreement (the “Sales Agreement”) with BTIG, LLC (“BTIG”) under 
which it may offer and sell its common stock from time to time through BTIG as its sales agent. The Sales Agreement initially capped the amount of common 
stock  that  could  be  sold  under  the  Sales  Agreement  to  $100.0  million.  In  December  2023,  the  Sales  Agreement  was  amended  to,  among  other  things, 
remove the maximum dollar amount of common stock that can be sold under the Sales Agreement. 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.

During 2023, the Company issued and sold 1,935,214 shares of its common stock at a weighted-average price of $1.85 per share under the Sales 

Agreement and received $3.5 million in proceeds, net of commissions.

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.  Historically,  the  Company  has  not 
experienced significant credit losses from accounts receivable. Multiple customers have provided more than 10% of total revenue in the periods presented, 
or accounted for more than 10% of accounts receivable at each respective balance sheet date, as follows:

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”).

The  Company  derives  revenue  from  the  sale  of  sequencing  and  data  analysis  services.  Contracts  are  in  the  form  of  a  combination  of  signed 
agreements, statements of work, and/or purchase orders. 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. Revenue is recognized at a point in time when test results are transferred to the customer. The Company 
has elected to exclude all sales and value added taxes from the measurement of the transaction price. 

Standard payment terms are typically 90 days or less from the invoice date, but may vary. In instances where the timing of revenue recognition 
differs from the timing of 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 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, product development, collaborations, and studies; 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. 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.

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 sufficient trading history for the Company's common stock does not yet exist. 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,  estimated 

dividend yield is 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.  Comprehensive  loss  consists  of  net 

loss, cumulative translation adjustments, and 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  consolidated 

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

73

 
Table of Contents

Undistributed  earnings  of  foreign  subsidiaries  are  assumed  to  be  indefinitely  reinvested  and,  accordingly,  no  U.S.  income  taxes  have  been

provided thereon.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid investments with original 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 and U.S. Treasury bills, 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

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 are also 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.  Treasury  notes,  U.S.  Treasury  bills,  commercial  paper,  and  U.S. 
government agency bonds.

Any discount or premium arising at purchase is accreted or amortized to interest income or expense. Unrealized gains and losses are included in 
accumulated  other  comprehensive  income  (loss)  in  stockholders’  equity.  Realized  gains  and  losses  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. If an available-for-sale debt security's fair value is less than its 
amortized  cost  basis,  the  Company  evaluates  whether  the  decline  is  the  result  of  a  credit  loss,  in  which  case  an  impairment  is  recorded  through  an 
allowance for credit losses.

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.  The  Company  maintains  an  allowance  for  credit 
losses, consisting of known specific troubled accounts as well as an amount based on overall estimated potential uncollectible accounts receivable based on 
historical experience and review of their current credit quality. Expected credit losses are recorded as selling, general and administrative expenses in the 
consolidated statements of operations.

Table of Contents

Inventory and Other Deferred Costs

Inventory consists of raw materials and supplies used to fulfill customer contracts and the Company's research and development activities, and is 
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 materials 
consumed and work performed on customer orders that have yet to be completed and recognized as revenue and cost of revenue. Other deferred costs are 
also comprised of direct labor and overhead costs incurred.

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 laboratory equipment and computer 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  12  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, 2023, 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 and any lease prepayments. 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. Fixed lease payments are recognized as an expense on a straight-line basis over the lease term. Variable lease costs are amounts owed 
by us to a lessor that are not fixed, such as reimbursement for common area maintenance, operating expenses, utilities, or other costs that are subject to 
fluctuation from period to period. 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.

Warrant Liability

Changes  in  fair  value  of  liability  classified  warrants  are  recognized  within  "Other  income  (expense),  net"  in  the  consolidated  statements  of 
operations. Warrant liabilities are classified as short-term or long-term based on their remaining contractual periods. Cash proceeds in connection with the 
issuance of warrants for the Company's common stock are presented as financing activities in the consolidated statements of cash flows.

Recent Accounting Pronouncements

New Accounting Pronouncements Adopted

In June 2016, the FASB issued Accounting Standards Update (“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. The Company adopted the new guidance as of the beginning of the first quarter of 2023 by means of 
a cumulative-effect adjustment to opening retained earnings. The adoption did not have a significant impact on the consolidated financial statements.

New Accounting Pronouncements Not Yet Adopted

In  December  2023,  the  FASB  issued  ASU  2023-09,  Income  Taxes  (Topic  740):  Improvements  to  Income  Tax  Disclosures,  which  enhances 

transparency about income tax information through improvements to income tax disclosures primarily related to the rate

reconciliation and income taxes paid information. The guidance will be effective for the Company's annual period ending December 31, 2025. The Company 
is currently evaluating the impact of the new guidance on its income tax disclosures.

Note 3. Revenue

The Company disaggregates revenue by the following four customer types:

•

•

•

•

Pharma tests and services includes sales of testing services and data analytics for clinical trials and research to pharmaceutical companies 
in support of their drug development programs. Contracts typically contemplate a single project and involve a range of tests and analytics to 
fulfill the requirements of each particular project.

Enterprise  sales  includes  sales  of  tumor  profiling  and  diagnostic  tests  directly  to  another  business  as  an  input  to  their  products.  The 
Company is typically contracted to deliver specified tests and analytics in high volume over time. Revenue from the Company's partnership 
with Natera to provide advanced tumor analysis for use in Natera's MRD test makes up substantially all of the revenue in this category.

Population  sequencing  includes  sales  of  genomic  sequencing  services  and  data  analytics  to  support  large-scale  genetic  research 
programs. The Company is typically contracted to perform whole genome sequencing and provide data that can be used for analysis across 
a large volume of samples. All of the revenue within this category is from the Company's partnership with the VA MVP.

Other includes sales of genomic tests and analytics to universities and non-profits. Other also includes sales of diagnostics tests ordered by 
healthcare providers for cancer patients, which was insignificant for periods presented.

Amounts collected in advance of services being provided are deferred as contract liabilities in the consolidated balance sheets. The associated 
revenue  is  recognized,  and  the  contract  liability  is  reduced,  as  the  services  are  subsequently  performed.  As  of  December  31,  2023,  amounts  related  to 
unfulfilled  services  under  contracts  with  an  original  expected  duration  of  more  than  one  year  was  $5.7  million.  The  Company  expects  to  recognize 
approximately $1.8 million of this amount in the next 12 months, and the remaining $3.9 million in the 12 months after that. Revenue recognized that was 
included  in  the  contract  liability  balance  at  the  beginning  of  each  reporting  period  was  $0.4  million,  $3.5  million,  and  $19.1  million  for  the  years  ended

Marketable debt securities at December 31, 2023 have maturities due in less than 12 months. No security has been in a continuous unrealized 

loss position for more than 12 months and the Company does not consider any of its marketable debt securities to be impaired.

Tempus Warrants

The  Black-Scholes  option-pricing  model  was  used  to  estimate  fair  value  of  the  warrants  issued  to  Tempus  AI,  Inc.  (formerly  known  as  Tempus 
Labs, Inc., and referred to herein as "Tempus") at the date of issuance, November 28, 2023, and at each subsequent balance sheet date. Assumptions used 
are  listed  below,  which  are  Level  3  fair  value  inputs.  Expected  term  is  equal  to  the  remaining  contractual  periods  of  each  of  the  two  warrants.  Expected 
volatility was based on the Company's actual historical volatility over the expected terms of the warrants. The risk-free interest rate was based on the U.S. 
Treasury yield curve over the expected term of the warrants. Refer to Note 8 for further information about the warrants issued to Tempus.

In April 2021, the Company entered into a secured payment agreement with a financing entity to finance the purchase of $2.4 million of internal 
use software licenses and related software maintenance from a vendor. The financing entity and vendor are not related. The Company repaid the financed 
amount in three equal payments of $0.8 million in May 2021, May 2022, and May 2023. The payment agreement was 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.

The  Company  entered  into  two  more  secured  payment  agreements  in  April  2021  and  July  2022,  with  the  same  financing  entity,  to  finance  the 
purchase of $3.1 million  of  computer hardware and related hardware  maintenance  and  $1.3  million  of  internal  use  software  licenses  and  related  ongoing 
support, respectively. The Company is required to pay three equal payments of $1.0 million in July 2021, June 2022, and June 2023 for the first agreement, 
and  three  equal  payments  of  $0.4  million  in  September  2022,  September  2023,  and  September  2024  for  the  second  agreement.  The  nature  of  these 
agreements and resulting accounting treatment are the same as the payment agreement described in the preceding paragraph, except the imputed interest 
rate was 9% for the July 2022 agreement.

The total initial present value of the payment agreements was $6.4 million and presented as proceeds from loans in the financing activities section 
of 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. Repayments are presented as financing cash outflows. Interest expense was $0.1 million for 
the year ended December 31, 2023 and $0.2 million for each of the years ended December 31, 2022 and 2021. 

Lab Equipment Loan

In November 2023, the Company purchased lab equipment from one of its main vendors for $3.4 million. Extended payment terms were provided 
to the Company through a financial solutions partner of the vendor. Terms included a 30% down payment and 24 equal monthly payments for the remaining 
balance, with such monthly payments commencing in January 2024, and no interest or financing charges. Title for the lab equipment transferred immediately 
upon delivery to the Company. The financial solutions partner retains a security interest until payoff is complete at the end of 2025. The purchase price for
the lab equipment was equal to the cash price and thus the impact of imputing interest would have been de minimis.

The total financed amount of $3.4 million is presented as proceeds from loans in the financing activities section of the consolidated statements of 
cash flows. Such amounts were used to purchase lab equipment and are reflected as cash outflows in the investing activities section. Repayments, including 
both the down payment and future monthly payments, are presented as financing cash outflows.

Note 7. Leases

In  2021,  the  Company  entered  into  a  noncancelable  operating  lease  for  approximately  100,000  square  feet  in  Fremont,  California  used  for 
laboratory operations and its corporate headquarters. The lease term is 13.5 years and commenced in October 2022. The Company gained early access to 
the premises for the purpose of constructing and installing tenant improvements, for which the landlord

Table of Contents

contributed $15.1 million. Such contributions were accounted for as lease incentives and are recognized as reductions to lease expense over the lease term. 
The lease expires at the end of March 2036 and includes two options to extend the term for a period of five-years per option at market rates. The Company 
determined the extension options are not reasonably certain to be exercised. The lease includes escalating rent payments.

The Company has a noncancelable operating lease expiring in November 2027 for 31,280 square feet in Menlo Park, California previously used 
for laboratory operations and its former corporate headquarters. The lease includes escalating rent payments. In 2021, the Company expanded the leased 
premises by an additional 14,710 square feet of space (the “Expansion Lease”). The Expansion Lease expired at the end of December 2022 and was not 
extended. The Company moved all laboratory operations to the Fremont facility during the third quarter of 2023 and is actively marketing the vacated Menlo 
Park space for sublease.

The Company has noncancelable operating leases for data center space expiring between 2025 and 2026. The leases include renewal options 
that the Company determined are not reasonably certain to be exercised. During 2023, the data center operator agreed to terminate a portion of the lease at 
no cost. The Company remeasured the remaining lease liability and derecognized $0.6 million of operating lease liabilities and right-of-use assets.

The Company had an operating lease for laboratory space in Shanghai, China that was terminated early upon both parties' approval during 2023. 
The early termination did not result in any material penalties or charges in the Company's consolidated statements of operations. Separately, the Company 
also has various other short-term leases.

As of December 31, 2023, operating leases had a weighted-average remaining lease term of 10.4 years and a weighted-average discount rate of 
10.5%. Discount rates are based on estimates of the Company's incremental borrowing rate, as the discount rates implicit in the leases cannot be readily 
determined. Future lease payments under operating leases as of December 31, 2023 were as follows (in thousands):

During the year ended December 31, 2023, the Company also recorded a $5.6 million impairment loss for operating lease right-of-use assets as a 

result of the change in use of the Menlo Park office.

Lease Impairment

During 2023, the Company completed the move of its laboratory operations from its Menlo Park facility to its Fremont facility and began actively 
marketing the Menlo Park space for sublease. Accordingly, the Company evaluated the ongoing value of the operating lease right-of-use asset associated 
with  the  Menlo  Park  facility.  Based  on  this  evaluation,  the  Company  determined  that  the  right-of-use  asset  with  a  carrying  amount  of  $6.7 million was no 
longer recoverable and was impaired and wrote it down to its estimated fair value of $1.1 million, which resulted in a noncash impairment loss of $5.6 million. 
Estimated  fair  value  was  based  on  expected  future  sublease  cash  flows  (with  the  assistance  of  a  third-party  real  estate  broker),  net  of  brokerage 
commissions and estimated tenant incentives,

discounted at a market rate of return on similar assets. The estimation of fair value also included expected downtime prior to the commencement of a future 
sublease.

Note 8. Tempus Agreement

Overview

On  November  25,  2023,  the  Company  entered  into  a  Commercialization  and  Reference  Laboratory  Agreement  (the  “Tempus  Agreement”)  with 
Tempus pursuant to which Tempus will market the Company's Personal Dx test in the United States and the Company will conduct development activities to 
analytically validate the test in breast cancer, lung cancer and immuno-oncology monitoring indications. The Company will perform tests ordered by patients 
through Tempus and the Company will bill such patients or payors.

In  consideration  of  the  Company  performing  development  activities,  Tempus  will  pay  the  Company  fees  of  up  to  $12  million  (the  "Market 
Development Fees"), consisting of an activation fee of $3 million, a first milestone fee of $3 million (upon achievement of a specified clinical validation), and 
a second milestone fee payable in six quarterly installments totaling $6 million (subject to achieving two additional clinical validations). If the Company does 
not  achieve  the  second  milestone  by  June  2024,  Tempus  may  withhold  installment  payments,  and  Tempus  will  have  the  right  to  terminate  the  Tempus 
Agreement or convert it to a non-exclusive arrangement. Upon termination or conversion, the Company will refund to Tempus fees received other than the 
activation fee, subject to certain reductions.

The Company will compensate Tempus for the fair market value of order requisition services (Tempus will enable its base of ordering providers to 
order  the  Personalis  test  and  provide  specimen  collection  and  procurement  support)  and  results  delivery  services  (Tempus  will  provide  results  delivery 
services  from  test  completion  to  report  delivery)  on  a  per-test  basis.  In  addition,  the  parties  will  perform  co-promotion  activities  and  the  Company  will 
compensate Tempus for the fair market value of promotional and commercialization services provided by Tempus in an amount up to $9.6 million.

The Tempus Agreement also grants Tempus access to initial and longitudinal genomic data derived from performance of the tests and Tempus will 
have  the  right  to  use  such  data.  If  Tempus  licenses  such  data  to  a  third  party  and  Tempus  recognizes  revenue  from  such  license,  Tempus  will  pay  the 
Company a percentage of its gross revenues attributable to such license that is in the range of 10 to 20 percent. Such revenue share shall be payable during 
the term of the agreement and for 10 years thereafter.

Additionally, in consideration of Tempus' obligations to the Company under the agreement, on November 28, 2023, the Company issued warrants 

to Tempus. See "Tempus Warrants" section further below for discussion.

Pursuant  to  the  agreement,  the  Company  will  not  allow  another  third  party  to  market  the  test  in  such  indications  and  Tempus  will  not  market 
another tumor-informed molecular residual disease test for use in such indications (whether its own or that of a third party), in each case subject to certain 
exceptions. These exclusivity obligations terminate on December 31, 2027, to the extent they do not expire earlier. In addition, each party has the right to 
convert the Tempus Agreement to a non-exclusive arrangement upon the occurrence of certain specified events.

The term of the Tempus Agreement is five years, which may be extended for successive one-year terms. Either party may terminate the Tempus 
Agreement  for  convenience  upon  18  months  prior  written  notice.  Tempus  may  terminate  the  agreement  if  the  Company  does  not  achieve  the  second 
milestone by a specified date.

Impact of Tempus Agreement on the Consolidated Financial Statements

The  Company  had  achieved  the  first  clinical  validation  milestone  at  the  time  of  entering  the  Tempus  Agreement  and  was  therefore  entitled  to 
Market Development Fees of $6 million, consisting of the first milestone fee of $3 million and the activation fee of $3 million. These proceeds of $6 million 
were received in 2023 and allocated to the Tempus Warrants (described below). Except for receipt of the proceeds and issuance of the warrants, there were 
no  other  activities  under  the  Tempus  Agreement  that  impacted  the  Company's  consolidated  balance  sheets  or  consolidated  statements  of  operations  for 
periods presented.

Tempus Warrants

In consideration of Tempus’ obligations to Personalis under the agreement, on November 28, 2023, the Company issued to Tempus (1) a warrant 
to purchase up to 4,609,400 shares of Personalis common stock at an exercise price per share of $1.50, with an expiration date of December 31, 2024 (the 
“First  Warrant”),  and  (2)  a  warrant  to  purchase  up  to  4,609,400  shares  of  Personalis  common  stock  at  an  exercise  price  per  share  of  $2.50,  with  an 
expiration  date  of  December  31,  2025  (the  “Second  Warrant”  and,  together  with  the  First  Warrant,  the  “Tempus  Warrants”).  The  Tempus  Warrants  are 
exercisable  for  cash  at  any  time  prior  to  the  applicable  expiration  date,  may  be  net  exercised  in  certain  circumstances,  and  will  be  automatically  net 
exercised in connection with a change of control of Personalis if the value ascribed to the consideration to be paid for one share of common stock is greater 
than the applicable exercise price. If Tempus acquires any shares of common stock directly from the Company other than by exercising the Warrants (any 
such shares, “Non-Warrant Shares”), then the total number of shares issuable upon exercise of the Tempus Warrants will be reduced by the Non-Warrant 
Shares on a share-for-share basis, proportionally between the First Warrant and the Second Warrant based on how many shares are then underlying the 
Warrants.  Subject  to  limited  exceptions,  neither  the  warrants  nor  any  interest  therein  may  be  transferred  or  assigned  without  the  prior  written  consent  of 
Personalis.

81

 
Table of Contents

Because the number of shares issuable upon settlement are subject to adjustment if Tempus acquires Non-Warrant Shares, the Tempus Warrants 
are classified as liability instruments and are subject to remeasurement at each balance sheet date, with changes in fair value recognized as Other Income 
(Expense) in the consolidated statements of operations. Fair value of the two warrants were estimated at the date of issuance, November 28, 2023, using 
the  Black-Scholes  option-pricing  model.  Since  the  initial  fair  value  of  $6.9  million  exceeded  the  total  proceeds  from  Tempus  of  $6  million,  a  loss  of  $0.9 
million was immediately recognized within Other Income (Expense). None of the remaining Market Development Fees of $6 million  were allocated to the 
warrants as such proceeds are contingent upon the Company achieving additional clinical validation milestones.

See Note 5 Fair Value Measurements for discussion of inputs used in the measurement of the Tempus Warrants as well as the remeasurement at 
December 31, 2023. Fair value of the Tempus Warrants increased by $3.1 million as of December 31, 2023. The increase in fair value, plus the immediate 
loss of $0.9 million recognized upon issuance, resulted in a $4.0 million expense recognized in Other Income (Expense) in the consolidated statements of 
operations during the year ended December 31, 2023.

Note 9. Restructuring and Other Charges

Costs related to the Company's reductions in workforce and closure of its China operations are included within Restructuring and Other Charges 
in  the  consolidated  statements  of  operations.  A  reconciliation  of  the  beginning  and  ending  related  liability  balances,  included  within  Accrued  and  Other 
Current Liabilities in the consolidated balance sheets, is as follows (in thousands):

In  January  2023,  the  Company  initiated  a  reduction  in  workforce  to  reduce  operating  costs  and  improve  operating  efficiency.  The  workforce 
reduction affected nearly 100 employees and was substantially completed during the first quarter of 2023. The Company recognized $3.1 million in one-time 
employee termination benefits in connection with the reduction in workforce, comprising separation pay and healthcare benefits payable in cash, all of which 
were paid by the end of the second quarter of 2023.

In December 2023, the Company initiated a second reduction in workforce to further reduce operating costs and improve operating efficiency. The 
workforce reduction affected approximately 60 employees and will be completed during the first quarter of 2024. The Company recognized $4.0 million in 
one-time employee termination benefits in connection with the reduction in workforce, comprising separation pay and healthcare benefits payable in cash. 
Approximately $3.1  million  of  such  expenses  were  unpaid  as  of  December  31,  2023  and  are  expected  to  be  paid  during  the  first  quarter  of  2024.  The 
Company does not expect to incur any material additional costs in connection with the second reduction in workforce.

Closure of China Operations

During  the  first  half  of  2023,  the  Company  terminated  its  operations  in  China  with  the  objective  of  streamlining  international  operations  and 
reducing operating costs. The disposal does not qualify for reporting as a discontinued operation because it does not represent a strategic shift that has or 
will have a major effect on our operations and financial results. The Company completed the process of dissolving the Personalis (Shanghai) Ltd entity in 
February 2024.

Expenses of $0.9 million were recognized in connection with closure activities, of which $0.3 million was related to one-time employee termination 
benefits for the Company's 12 former employees located in China and were payable in cash. Substantially all of the terminations were completed during the 
first quarter of 2023, along with the related cash outlays. The remaining $0.6 million in expenses were comprised primarily of noncash charges, including 
losses on disposal of fixed assets and impairments of other assets.

Note 10. Stock-Based Compensation

The Company maintains the following equity incentive plans:

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 were 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, 2023 were as follows:

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 $2.10 on December 31, 2023 and the exercise prices of the underlying stock options. Out-of-the money stock options are excluded from aggregate 
intrinsic value.

The weighted-average grant date fair value of options granted was $1.81, $3.21, and $13.14 per share for the years ended December 31, 2023, 
2022,  and  2021,  respectively.  As  of  December  31,  2023,  the  unrecognized  stock-based  compensation  of  unvested  options  was  $7.2  million,  which  is 
expected to be recognized over a weighted-average period of 2.02 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. Fair value of stock options is recognized as compensation expense on a straight-line basis over the requisite service periods of the 
awards. Fair value of stock options was estimated using the following range of assumptions:

The Company grants RSUs to employees to receive shares of the Company’s common stock. The RSUs awarded are subject to the 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. The Company accounts for the fair value of 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 $2.10 on December 31, 2023. 
As of December 31, 2023, the unrecognized stock-based compensation cost of unvested RSUs was $9.5 million, which is expected to be recognized over a 
weighted-average period of 1.87 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.

On  August  2,  2022,  the  Company  filed  a  complaint  in  the  U.S.  District  Court  for  the  District  of  Colorado  (the  "District  Court")  against  Foresight 
Diagnostics  Inc.  (“Foresight”)  for  patent  infringement.  The  complaint  is  based  on  the  Company’s  U.S.  Patent  No.  10,450,611  (the  “’611  Patent”),  entitled 
“Personalized  Genetic  Testing,”  our  U.S.  Patent  No.  11,299,783  (the  “’783  Patent”),  entitled  “Methods  and  Systems  For  Genetic  Analysis,”  and  our  U.S. 
Patent  No.  11,384,394  (the  “’394  Patent”),  entitled  “Methods  and  Systems  for  Genetic  Analysis.”  The  ‘611  Patent  was  granted  on  October  22,  2019,  and 
relates to methods for personalized genetic testing by performance of sequencing assays on biological samples. The ‘783 Patent was granted on April 12, 
2022,  and  relates  to  methods  for  sample  processing  and  data  analysis  by  performance  of  sequencing  assays  on  biological  samples  that  can  aid  in  the 
diagnosis, monitoring, treatment, and prevention of one or more diseases. The ‘394 Patent was granted on July 12, 2022, and relates to methods for sample 
processing  and  analysis  to  aid  in  the  diagnosis,  monitoring,  treatment,  and  prevention  of  disease.  On  August  17,  2022,  the  Company  filed  an  amended 
complaint for patent infringement against Foresight. The amended complaint added our U.S. Patent No. 11,408,033 (the “’033 Patent”), entitled “Methods 
and Systems for Genetic Analysis.” The ‘033 Patent was granted on August 9, 2022, and relates to methods for sample processing and analysis to aid in the 
diagnosis, monitoring, treatment, and prevention of disease. The Company is seeking remedies including injunctive relief, damages and costs. On October 
12, 2022, Foresight filed its answer and counterclaims in the matter, seeking declaratory judgment and alleging that its solid tumor recurrence test does not 
infringe the Company’s asserted patents and that the claims of our asserted patents are invalid and/or unenforceable. On November 2, 2022, the Company 
filed its answer to Foresight’s counterclaims. The Company intends to vigorously defend against these counterclaims.

Between  November  30,  2022  and  February  10,  2023,  inclusive,  Foresight  filed  four  inter partes  review  petitions  with  the  USPTO,  seeking  to 
invalidate the four patents that we are asserting against Foresight in our first patent infringement action. Also on November 30, 2022, Foresight filed a motion 
to stay our first patent infringement action in the District Court pending the resolution of the inter partes review proceedings that Foresight has requested. On 
January 24, 2023, the District Court granted Foresight’s motion to stay. On June 13, 2023, the USPTO issued decisions granting inter partes reviews of the 
'394 and '033 Patents. On August 8, 2023, the USPTO issued decisions granting inter partes reviews of the '611 and '783 Patents.

On June 26, 2023, the Company filed a second complaint in the District Court against Foresight for patent infringement. The complaint is based on 
the Company’s U.S. Patent No. 11,584,968 (the “’968 Patent”), entitled “Methods For Using Mosaicism in Nucleic Acids Sampled Distal to Their Origin,” our 
U.S. Patent No. 11,649,507 (the “’507 Patent”), entitled “Methods for Using Mosaicism in

Nucleic Acids Sampled Distal to Their Origin,” and our U.S. Patent No. 11,643,685 (the “’685 Patent”), entitled “Methods and Systems For Genetic Analysis.” 
The ’968 Patent was granted on February 21, 2023, and relates to methods for improving detection and monitoring of human diseases. The ’507 Patent was 
granted  on  May  16,  2023,  and  relates  to  methods  for  detection  and  monitoring  of  human  disease  by  providing  spatial  or  developmental  localization  of 
mutations within the body which is used in monitoring states of health in tissues of the body. The ’685 Patent was granted on May 9, 2023, and relates to 
methods for sample processing and analysis to aid in the diagnosis, monitoring, treatment, and prevention of disease. The Company is seeking remedies 
including injunctive relief, damages and costs. On August 10, 2023, Foresight filed a motion to dismiss the Company’s second complaint. On August 31, 
2023, the Company filed a response to Foresight’s motion and also filed an amended complaint. On September 6, 2023, the District Court denied Foresight’s 
motion as moot in light of the Company’s amended complaint. On September 14, 2023, Foresight filed its answer and counterclaims in the matter, seeking 
declaratory judgment and alleging that its solid tumor recurrence test does not infringe the Company’s asserted patents in the Company’s second patent 
infringement  action  and  that  the  Company’s  asserted  patents  in  that  action  are  invalid  and/or  unenforceable.  On  October  5,  2023,  the  Company  filed  its 
answer to Foresight’s counterclaims. The Company intends to vigorously defend against these counterclaims. 

On  October  20,  2023,  Foresight  filed  a  motion  to  consolidate  the  Company’s  two  patent  infringement  actions  in  the  District  Court,  and  if 
consolidated, to maintain the stay as to all of the Company’s asserted patents pending the resolution of the first four inter partes review proceedings and the 
three additional inter partes review petitions that Foresight has alleged it will file as soon as it is permitted by statute to do so, seeking to invalidate the three 
patents that the Company is asserting against Foresight in the Company’s second patent infringement action. The Company filed its opposition to Foresight’s 
motion to consolidate and stay the infringement actions on November 8, 2023. On November 22, 2023, Foresight filed its fifth inter partes review petition with 
the USPTO, seeking to invalidate the ’968 Patent that we are asserting against Foresight in our second patent infringement action. On January 23, 2024, the 
District Court granted Foresight’s motion to consolidate and stay our two infringement actions against Foresight. The USPTO has yet to issue a decision 
regarding whether it will institute an inter partes review of our ’968 Patent.

Litigation is inherently unpredictable, and, except for events that have already occurred, it is too early in the foregoing proceedings to predict the 
outcome of these proceedings, or any impact they may have on us. As such, the estimated financial effect associated with this complaint cannot be made as 
of the date of filing of this Annual Report on Form 10-K. Litigation is a significant ongoing expense with an uncertain outcome and may in the future be a 
material expense for us. Management believes this investment is important to protect our intellectual property position, even recognizing the uncertainty of 
the outcome.

The  Company  is  also  subject  to  claims  and  assessments  from  time  to  time  in  the  ordinary  course  of  business.  Accruals  for  litigation  and  loss 
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. Except for the matter described in the first four paragraphs of this Note 11, as of 
December 31, 2023, 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 12. Basic and Diluted Net Loss Per Common Share

Basic net loss per common share is computed by dividing 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  stock  options, 
assumed release of outstanding RSUs, assumed issuance of common stock under the ESPP, and the assumed exercise of Tempus Warrants. The Company 
incurred  net  losses  in  the  periods  presented,  and  as  a  result,  potential  common  shares  from  stock  options,  RSUs,  ESPP  issuances,  and  the  Tempus 
Warrants were not included in the diluted shares used to calculate net loss per share, as their inclusion would have been anti-dilutive.

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 $30.4 million and $32.9 million during the years ended December 31, 2023 and 2022, respectively.

Net Operating Loss and Tax Credit Carryforwards

As of December 31, 2023, the Company had a net operating loss carryforward for federal income tax purposes of $285.5 million, of which $86.1 
million is subject to expiration beginning in 2031. The Company had a total state net operating loss carryforward of $274.7 million, which will begin to expire 
in 2031.  Utilization  of  some  of  the  federal  and  state  net  operating  loss  and  credit  carryforwards  are  subject  to  annual  limitations  due  to  the  “change  in 
ownership” provisions of the Internal Revenue Code of 1986 (specifically Section 382), as amended, and similar state provisions. The Company performed a 
Section  382  analysis  through  December  31,  2023  and  determined  that  ownership  changes  occurred  in  the  year  2011  and  again  in  2020.  The  ownership 
changes identified had no significant impact on federal and state net operating losses. The annual limitations may result in the expiration of net operating 
losses and credits before utilization in the future.

As of December 31, 2023, the Company has federal credits of $12.2 million, which will begin to expire in 2031 and state research credits of $10.5 
million, which have no expiration date. These tax credits are subject to the same limitations discussed above. The Company determined that the ownership 
changes identified above had no significant impact on federal and state research credits.

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.

Although  it  is  reasonably  possible  that  certain  unrecognized  tax  benefits  may  increase  or  decrease  within  the  next  12  months  due  to  tax 
examination changes, settlement activities, expirations of statute of limitations, or the impact on recognition and measurement considerations related to the 
results of published tax cases or other similar activities, the Company does not anticipate any significant changes to unrecognized tax benefits over the next 
12 months. During the years ended December 31, 2023, 2022, and 2021, no interest or penalties were required to be recognized relating to unrecognized 
tax benefits.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Stockholders and Board of Directors
Personalis, Inc.
Fremont, California

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Personalis, Inc. and subsidiaries (the “Company”) as of December 31, 2023, the related 
consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for the year then ended, and the related notes (collectively 
referred  to  as  the  “consolidated  financial  statements”).  In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the 
financial  position  of  the  Company  at  December  31,  2023,  and  the  results  of  its  operations  and  its  cash  flows  for  the  year  then  ended,  in  conformity  with 
accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s 
consolidated  financial  statements  based  on  our  audit.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board 
(United  States)  (“PCAOB”)  and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the 
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our 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  the  consolidated  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  The  Company  is  not 
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an 
understanding  of  internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal 
control over financial reporting. Accordingly, we express no such opinion.

Our  audit  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  consolidated  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 consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis 
for our opinion.

Critical Audit Matter

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

Accounting for Tempus Agreement and Tempus Warrants

As described in Note 8 to the consolidated financial statements, the Company entered into a Commercialization and Reference Laboratory Agreement (the 
“Tempus Agreement”) with Tempus Labs, Inc. (“Tempus”) in November 2023. In connection with the Tempus Agreement, the Company issued warrants to 
purchase  shares  of  the  Company’s  common  stock  to  Tempus  (“Tempus  Warrants”).  As  of  December  31,  2023,  the  Company  received  $6  million  of  cash 
proceeds from Tempus. The Tempus Warrants are classified as liability instruments, and the $6 million of proceeds were allocated to the Tempus Warrants.

We identified the evaluation of (i) the financial statement classification of the Tempus Warrants, and (ii) allocation of the proceeds among the elements of the 
Tempus  Agreement  and  the  Tempus  Warrants  as  a  critical  audit  matter.  Our  principal  considerations  included  the  existence  of  accounting  complexities 
related  to  such  evaluation  and  significant  judgments  involved  in  the  interpretation  of  the  terms  of  the  agreements  and  in  the  application  of  appropriate 
accounting  guidance.  Auditing  these  elements  required  challenging  and  complex  auditor  judgment  due  to  the  nature  and  extent  of  audit  effort  required, 
including the extent of specialized skills or knowledge needed.

The primary procedures we performed to address this critical audit matter included:

•

•

Reviewing  and  analyzing:  (i)  the  terms  of  the  Tempus  Agreement  and  Tempus  Warrants,  and  (ii)  the  Company’s  application  of  the  relevant 
accounting literature including the allocation of the proceeds received to the Tempus Warrants.

Utilizing  personnel  with  specialized  skills  and  knowledge  to  assist  in:  (i)  evaluating  relevant  terms  of  the  Tempus  Agreement  and  Tempus 
Warrants  in  relation  to  the  appropriate  accounting  literature,  and  (ii)  assessing  the  appropriateness  of  the  conclusions  reached  by  the 
Company.

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, 2022, the related 
consolidated statements of operations, comprehensive loss, stockholder's equity and cash flows, for each of the two years in the period ended December 
31, 2022, 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, 2022, and the results of its operations and its cash flows for each of the two years in the 
period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor 
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of 
internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial 
reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in 
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as 
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We began serving as the Company’s auditor in 2018. In 2023 we became the predecessor auditor.

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

None.

Item 9A. Controls and Procedures. 

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer ("CEO") and chief financial officer ("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, 2023, 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 SEC’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,  2023  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,  2023,  our  internal  control  over  financial  reporting  was  effective  in  providing 
reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with 
generally accepted accounting principles in the United States of America. 

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

as we qualify as a non-accelerated filer.

Changes in Internal Control

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rule 
13a-15(f) of the Exchange Act. An evaluation was also performed under the supervision and with the participation of our management, including our CEO 
and our CFO, of any change in our internal control over financial reporting that occurred during our last fiscal quarter and that has materially affected, or is 
reasonably  likely  to  materially  affect,  our  internal  control  over  financial  reporting.  That  evaluation  did  not  identify  any  change  in  our  internal  control  over 
financial reporting that occurred during our latest fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over 
financial reporting.

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.

None.

Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections.

Not applicable.

1.

GENERAL. 

(a)Eligible Award Recipients.  The only persons eligible to receive grants of Awards under this Plan are individuals who satisfy 
the standards for inducement grants under Nasdaq Marketplace Rule 5635(c)(4) or 5635(c)(3), if applicable, and the related guidance under 
Nasdaq IM 5635-1. A person who previously served as an Employee or Director will not be eligible to receive Awards under the Plan, other 
than following a bona fide period of non-employment. Persons eligible to receive grants of Awards under this Plan are referred to in this Plan 
as “Eligible Employees.” These Awards must be approved by either a majority of the Company’s “Independent Directors” (as such term is 
defined  in  Nasdaq  Marketplace  Rule  5605(a)(2))  or  the  Company’s  compensation  committee,  provided  such  committee  comprises  solely 
Independent Directors (the “Independent Compensation Committee”) in order to comply with the exemption from the stockholder approval 
requirement for “inducement grants” provided under Rule 5635(c)(4) of the Nasdaq Marketplace Rules. Nasdaq Marketplace Rule 5635(c)(4) 
and  the  related  guidance  under  Nasdaq  IM  5635-1  (together  with  any  analogous  rules  or  guidance  effective  after  the  date  hereof,  the 
“Inducement Award Rules”).

(b)Available Awards.  The Plan provides for the grant of the following Awards: (i) Options, (ii) Stock Appreciation Rights, (iii) 
Restricted Stock Awards, (iv) Restricted Stock Unit Awards, (v) Performance Stock Awards, and (vi) Other Stock Awards.  All Options shall 
be Nonstatutory Stock Options.

(c) Purpose.  The Plan, through the grant of Awards, is intended to provide (i) an inducement material for certain individuals to 
enter into employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Marketplace Rules, (ii) incentives for such 
persons to exert maximum efforts for the success of the Company and any Affiliate and (iii) a means by which Eligible Employees may be 
given an opportunity to benefit from increases in value of the Common Stock.

2.

ADMINISTRATION.

(a)Administration by Board.  The Board will administer the Plan; provided, however, that Awards may only be granted by either 
(i) a majority of the Company’s Independent Directors or (ii) the Independent Compensation Committee. Subject to those constraints and the 
other constraints of the Inducement Award Rules, the Board may delegate some of its powers of administration of the Plan to a Committee or 
Committees, as provided in Section 2(c).

(b)Powers of Board.  The Board will have the power, subject to, and within the limitations of, the express provisions of the Plan

and the Inducement Award Rules:

To determine: (A) who will be granted Awards; (B) when and how each Award will be granted; (C) what type of 
Award will be granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise 
or otherwise receive cash or Common Stock under the Award; (E) the number of shares of Common Stock subject to, or the cash value of, an 
Award; and (F) the Fair Market Value applicable to an Award; provided, however, that Awards may only be granted by either (i) a majority of 
the Company’s Independent Directors or (ii) the Independent Compensation Committee.

suspension or termination of the Plan will not materially impair a Participant’s rights under the Participant’s then-outstanding Award without 
the Participant’s written consent, except as provided in subsection (viii) below.

(v)

(vi) To  amend  the  Plan  in  any  respect  the  Board  deems  necessary  or  advisable,  including,  without  limitation,  by 
adopting amendments relating to certain nonqualified deferred compensation under Section 409A of the Code and/or to ensure the Plan or 
Awards granted under the Plan are exempt from, or compliant with, the requirements for nonqualified deferred compensation under Section 
409A  of  the  Code,  subject  to  the  limitations,  if  any,  of  applicable  law.    Except  as  provided  in  Section  9(a)  relating  to  Capitalization 
Adjustments, if required by applicable law or listing requirements, the Company shall seek stockholder approval for any amendment of the 
Plan.  Except as otherwise provided in the Plan or an Award Agreement, no amendment of the Plan will materially impair a Participant’s

including,  but  not  limited  to,  amendments  to  provide  terms  more  favorable  to  the  Participant  than  previously  provided  in  the  Award 
Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided, however, that a Participant’s rights 
under any Award will not be impaired by any such amendment unless (A) the Company requests the consent of the affected Participant, and 
(B) such Participant consents in writing. Notwithstanding the foregoing, (1) a Participant’s rights will not be deemed to have been impaired 
by any such amendment if the Board, in its sole discretion, determines that the amendment, taken as a whole, does not materially impair the 
Participant’s rights, and (2) subject to the limitations of applicable law, if any, the Board may amend the terms of any one or more Awards 
without the affected Participant’s consent (A) to clarify the manner of exemption from, or to bring the Award into compliance with, Section 
409A of the Code; or (B) to comply with other applicable laws or listing requirements.

immaterial  modifications  to  the  Plan  or  any  Award  Agreement  that  are  required  for  compliance  with  the  laws  of  the  relevant  foreign 
jurisdiction).

(c) Delegation to Committee.  

(i)

General.  The Board may delegate some or all of the administration of the Plan to a Committee or Committees.  If 
administration  of  the  Plan  is  delegated  to  a  Committee,  the  Committee  will  have,  in  connection  with  the  administration  of  the  Plan,  the 
powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a subcommittee of 
the  Committee  any  of  the  administrative  powers  the  Committee  is  authorized  to  exercise  (and  references  in  this  Plan  to  the  Board  will 
thereafter be construed as being to the Committee or subcommittee, as applicable).  Any delegation of administrative powers

will be reflected in resolutions, not inconsistent with the provisions of the Plan, adopted from time to time by the Board or Committee (as 
applicable).  The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the 
Board some or all of the powers previously delegated.

(ii) Rule  16b-3  Compliance.    The  Committee  may  consist  solely  of  two  or  more  Non-Employee  Directors  in

(e) Repricing; Cancellation and Re-Grant of Awards.  Neither the Board nor any Committee will have the authority to reduce the 
exercise, purchase or strike price of any outstanding Option or SAR, unless the stockholders of the Company have approved such an action 
within twelve (12) months prior to such an event.

3.

SHARES SUBJECT TO THE PLAN.

(a)Share  Reserve.    Subject  to  Section  9(a)  relating  to  Capitalization  Adjustments,  the  aggregate  number  of  shares  of  Common 
Stock  that  may  be  issued  pursuant  to  Awards  will  not  exceed  1,350,000  shares.    Shares  may  be  issued  in  connection  with  a  merger  or 
acquisition  as  permitted  by  Nasdaq  Marketplace  Rule  5635(c)  or,  if  applicable  NYSE  Listed  Company  Manual  Section  303A.08,  AMEX 
Company Guide Section 711 or other applicable rule, and such issuance will not reduce the number of shares available for issuance under the 
Plan.    

(b)Reversion of Shares to the Share Reserve. If an Award or any portion thereof (i) expires or otherwise terminates without all of 
the  shares  covered  by  such  Award  having  been  issued  or  (ii)  is  settled  in  cash  (i.e.,  the  Participant  receives  cash  rather  than  stock),  such 
expiration, termination or settlement will not reduce (or otherwise offset) the number of shares of Common Stock that may be available for 
issuance under the Plan.  If any shares of Common Stock issued pursuant to an Award are forfeited back to or repurchased by the Company 
because of the failure to meet a contingency or condition required to vest such shares in the Participant, then the shares that are forfeited or 
repurchased will revert to and again become available for issuance under the Plan.  Any shares reacquired by the Company in satisfaction of 
tax withholding obligations on an Award or as consideration for the exercise or purchase price of an Award will again become available for 
issuance under the Plan. 

(c) Source of Shares.  The stock issuable under the Plan will be shares of authorized but unissued or reacquired Common Stock, 

including shares repurchased by the Company on the open market or otherwise.

4.

ELIGIBILITY.

(a)Eligibility for Specific Awards.  Awards may only be granted to persons who are Eligible Employees described in Section 1(a) 
of the Plan, where the Award is an inducement material to the individual’s entering into employment with the Company or an Affiliate within 
the  meaning  of  Rule  5635(c)(4)  of  the  Nasdaq  Marketplace  Rules  or  is  otherwise  permitted  pursuant  to  Rule  5635(c)  of  the  Nasdaq 
Marketplace Rules, provided, however, that Awards may not be granted to Eligible Employees who are providing Continuous Service only to 
any “parent” of the Company, as such term is defined in Rule 405 of the Securities Act, unless (i) the stock underlying such Awards is treated 
as “service recipient stock” under Section 409A of the Code (for example, because the Awards are granted pursuant to a corporate transaction 
such  as  a  spin  off  transaction),  (ii)  the  Company,  in  consultation  with  its  legal  counsel,  has  determined  that  such  Awards  are  otherwise 
exempt from Section 409A of the Code, or (iii) the Company, in consultation with its legal counsel, has determined that such Awards comply 
with the distribution requirements of Section 409A of the Code.

(b)Approval  Requirements.  All  Awards  must  be  granted  either  by  a  majority  of  the  Company’s  independent  directors  or  the 

Independent Compensation Committee.

5.

PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS.

Each Option or SAR will be in such form and will contain such terms and conditions as the Board deems appropriate. All Options 
will  be  Nonstatutory  Stock  Options  at  the  time  of  grant.  The  provisions  of  separate  Options  or  SARs  need  not  be  identical;  provided, 
however,  that  each  Award  Agreement  will  conform  to  (through  incorporation  of  provisions  hereof  by  reference  in  the  applicable  Award 
Agreement or otherwise) the substance of each of the following provisions:

(a)Term.  No Option or SAR will be exercisable after the expiration of 10 years from the date of its grant or such shorter period 

specified in the Award Agreement.

(b)Exercise Price.  The exercise or strike price of each Option or SAR will be not less than 100% of the Fair Market Value of the 
Common Stock subject to the Option or SAR on the date the Award is granted. Notwithstanding the foregoing, an Option or SAR may be 
granted with an exercise or strike price lower than 100% of the Fair Market Value of the Common Stock subject to the Award if such Award 
is granted pursuant to an assumption of or substitution for another option or stock appreciation right pursuant to a Corporate Transaction and 
in  a  manner  consistent  with  the  provisions  of  Section  409A  of  the  Code.    Each  SAR  will  be  denominated  in  shares  of  Common  Stock 
equivalents.

(c) Purchase Price for Options.  The purchase price of Common Stock acquired pursuant to the exercise of an Option may be paid, 
to  the  extent  permitted  by  applicable  law  and  as  determined  by  the  Board  in  its  sole  discretion,  by  any  combination  of  the  methods  of 
payment set forth below.  The Board will have the authority to grant Options that do not permit all of the following methods of payment (or 
otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to use a particular method 
of payment.  The permitted methods of payment are as follows:

(i)

by cash, check, bank draft or money order payable to the Company;

pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the 
issuance  of  the  stock  subject  to  the  Option,  results  in  either  the  receipt  of  cash  (or  check)  by  the  Company  or  the  receipt  of  irrevocable 
instructions to pay the aggregate exercise price to the Company from the sales proceeds;

(ii)

(iii)

by delivery to the Company (either by actual delivery or attestation) of shares of Common Stock;

(iv)

by  a  “net  exercise”  arrangement  pursuant  to  which  the  Company  will  reduce  the  number  of  shares  of  Common 
Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise 
price; provided, however, that the Company will accept a cash or other payment from the Participant to the extent of any remaining balance 
of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued.  Shares of Common Stock will no 
longer be subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the 
exercise  price  pursuant  to  the  “net  exercise,”  (B)  shares  are  delivered  to  the  Participant  as  a  result  of  such  exercise,  and  (C)  shares  are 
withheld to satisfy tax withholding obligations;  or

Agreement.

(v)

in any other form of legal consideration that may be acceptable to the Board and specified in the applicable Award 

(d)Exercise and Payment of a SAR.  To exercise any outstanding SAR, the Participant must provide written notice of exercise to 
the  Company  in  compliance  with  the  provisions  of  the  Stock  Appreciation  Right  Agreement  evidencing  such  SAR.    The  appreciation 
distribution payable on the exercise of a SAR will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value 
(on the date of the exercise of the SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which 
the Participant is vested under such SAR, and with respect to which the Participant is exercising the SAR on such date, over (B) the 

4.

 
 
aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such date.  
The appreciation distribution may be paid in Common Stock, in cash, in any combination of the two or in any other form of consideration, as 
determined by the Board and contained in the Award Agreement evidencing such SAR. 

(e) Transferability of Options and SARs.  The Board may, in its sole discretion, impose such limitations on the transferability of 
Options  and  SARs  as  the  Board  will  determine.    In  the  absence  of  such  a  determination  by  the  Board  to  the  contrary,  the  following 
restrictions on the transferability of Options and SARs will apply:

(i)

Restrictions on Transfer.  An Option or SAR will not be transferable except by will or by the laws of descent and 
distribution  (or  pursuant  to  subsections  (ii)  and  (iii)  below),  and  will  be  exercisable  during  the  lifetime  of  the  Participant  only  by  the 
Participant.  The Board may permit transfer of the Option or SAR in a manner that is not prohibited by applicable tax and securities laws. 
Except as explicitly provided in the Plan, neither an Option nor a SAR may be transferred for consideration. 

(ii) Domestic Relations Orders.  Subject to the approval of the Board or a duly authorized Officer, an Option or SAR 
may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation 
instrument. 

(iii) Beneficiary Designation.  Subject to the approval of the Board or a duly authorized Officer, a Participant may, by 
delivering written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, on the 
death  of  the  Participant,  will  thereafter  be  entitled  to  exercise  the  Option  or  SAR  and  receive  the  Common  Stock  or  other  consideration
resulting  from  such  exercise.    In  the  absence  of  such  a  designation,  upon  the  death  of  the  Participant  the  executor  or  administrator  of  the 
Participant’s estate will be entitled to exercise the Option or SAR and receive the Common Stock or other consideration resulting from such 
exercise. However, the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that 
such designation would be inconsistent with the provisions of applicable laws.

(f) Vesting  Generally.    The  total  number  of  shares  of  Common  Stock  subject  to  an  Option  or  SAR  may  vest  and  become 
exercisable in periodic installments that may or may not be equal.  The Option or SAR may be subject to such other terms and conditions on
the time or times when it may or may not be exercised (which may be based on the satisfaction of Performance Goals or other criteria) as the 
Board may deem appropriate.  The vesting provisions of individual Options or SARs may vary.  The provisions of this Section(f) are subject 
to  any  Option  or  SAR  provisions  governing  the  minimum  number  of  shares  of  Common  Stock  as  to  which  an  Option  or  SAR  may  be 
exercised.

(g)Termination  of  Continuous  Service.    Except  as  otherwise  provided  in  the  applicable  Award  Agreement  or  other  agreement 
between  the  Participant  and  the  Company,  if  a  Participant’s  Continuous  Service  terminates  (other  than  for  Cause  and  other  than  upon  the 
Participant’s death or Disability), the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to 
exercise such Award as of the date of termination of Continuous Service) within the period of time ending on the earlier of (i) the date that is 
90 days following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the applicable Award 
Agreement) and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement.  If, after termination of Continuous 
Service, the Participant does not exercise his or her Option or SAR (as applicable) within the applicable time frame, the Option or SAR will 
terminate.

(h)Extension of Termination Date.  If the exercise of an Option or SAR following the termination of the Participant’s Continuous 
Service (other than for Cause and other than upon the Participant’s death or Disability) would be prohibited at any time solely because the 
issuance  of  shares  of  Common  Stock  would  violate  the  registration  requirements  under  the  Securities  Act,  then  the  Option  or  SAR  will 
terminate on the earlier of (i) the expiration of a total period of time (that need not be consecutive) equal to the applicable post-termination 
exercise period after the termination of the Participant’s Continuous Service during which the exercise of the Option or SAR would not be in 
violation of such registration requirements, and (ii) the expiration of the term of the Option or SAR as set forth in the 

5.

 
 
applicable Award Agreement.  In addition, unless otherwise provided in a Participant’s Award Agreement, if the sale of any Common Stock 
received on exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would 
violate the Company’s insider trading policy, then the Option or SAR will terminate on the earlier of (i) the expiration of a period of months 
(that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the Participant’s Continuous 
Service  during  which  the  sale  of  the  Common  Stock  received  upon  exercise  of  the  Option  or  SAR  would  not  be  in  violation  of  the 
Company’s insider trading policy, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement.

(i) Disability of Participant.  Except as otherwise provided in the applicable Award Agreement or other agreement between the 
Participant and the Company, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may 
exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination 
of Continuous Service), but only within such period of time ending on the earlier of (i) the date 12 months following such termination of 
Continuous Service (or such longer or shorter period specified in the Award Agreement), and (ii) the expiration of the term of the Option or 
SAR as set forth in the Award Agreement.  If, after termination of Continuous Service, the Participant does not exercise his or her Option or 
SAR within the applicable time frame, the Option or SAR (as applicable) will terminate.

(j) Death  of  Participant.    Except  as  otherwise  provided  in  the  applicable  Award  Agreement  or  other  agreement  between  the 
Participant and the Company, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant 
dies  within  the  period  (if  any)  specified  in  the  Award  Agreement  for  exercisability  after  the  termination  of  the  Participant’s  Continuous 
Service for a reason other than death, then the Option or SAR may be exercised (to the extent the Participant was entitled to exercise such 
Option  or  SAR  as  of  the  date  of  death)  by  the  Participant’s  estate,  by  a  person  who  acquired  the  right  to  exercise  the  Option  or  SAR  by 
bequest  or  inheritance  or  by  a  person  designated  to  exercise  the  Option  or  SAR  upon  the  Participant’s  death,  but  only  within  the  period 
ending  on  the  earlier  of  (i)  the  date  18  months  following  the  date  of  death  (or  such  longer  or  shorter  period  specified  in  the  Award 
Agreement), and (ii) the expiration of the term of such Option or SAR as set forth in the Award Agreement.  If, after the Participant’s death, 
the Option or SAR is not exercised within the applicable time frame, the Option or SAR (as applicable) will terminate.

(k)Termination for Cause.  Except as explicitly provided otherwise in a Participant’s Award Agreement or other individual written 
agreement between the Company and the Participant, if a Participant’s Continuous Service is terminated for Cause, the Option or SAR will 
terminate immediately upon such Participant’s termination of Continuous Service, and the Participant will be prohibited from exercising his 
or her Option or SAR from and after the time of such termination of Continuous Service.

(l) Non-Exempt Employees.  If an Option or SAR is granted to an Employee who is a non-exempt employee for purposes of the 
Fair Labor Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least 
six months following the date of grant of the Option or SAR (although the Award may vest prior to such date). Consistent with the provisions 
of the Worker Economic Opportunity Act, (i) if such non-exempt Employee dies or suffers a Disability, (ii) upon a Corporate Transaction in 
which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or (iv) upon the Participant’s retirement 
(as such term may be defined in the Participant’s Award Agreement in another agreement between the Participant and the Company, or, if no 
such definition, in accordance with the Company’s then current employment policies and guidelines), the vested portion of any Options and 
SARs  may  be  exercised  earlier  than  six  months  following  the  date  of  grant.    The  foregoing  provision  is  intended  to  operate  so  that  any 
income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her 
regular rate of pay. To the extent permitted and/or required for compliance with the Worker Economic Opportunity Act to ensure that any 
income derived by a non-exempt employee in connection with the exercise, vesting or issuance of any shares under any other Award will be 
exempt from the employee’s regular rate of pay, the provisions of this Section 5(l) will apply to all Awards and are hereby incorporated by 
reference into such Award Agreements.

PROVISIONS OF AWARDS OTHER THAN OPTIONS AND SARS.

(a)Restricted  Stock  Awards.    Each  Restricted  Stock  Award  Agreement  will  be  in  such  form  and  will  contain  such  terms  and 
conditions  as  the  Board  will  deem  appropriate.    To  the  extent  consistent  with  the  Company’s  bylaws,  at  the  Board’s  election,  shares  of 
Common  Stock  may  be  (x)  held  in  book  entry  form  subject  to  the  Company’s  instructions  until  any  restrictions  relating  to  the  Restricted 
Stock Award lapse; or (y) evidenced by a certificate, which certificate will be held in such form and manner as determined by the Board.  The 
terms  and  conditions  of  Restricted  Stock  Award  Agreements  may  change  from  time  to  time,  and  the  terms  and  conditions  of  separate 
Restricted Stock Award Agreements need not be identical.  Each Restricted Stock Award Agreement will conform to (through incorporation 
of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

Consideration.    A  Restricted  Stock  Award  may  be  awarded  in  consideration  for  (A)  cash,  check,  bank  draft  or 
money order payable to the Company, (B) past or future services to the Company or an Affiliate, or (C) any other form of legal consideration 
that may be acceptable to the Board, in its sole discretion, and permissible under applicable law.

(i)

forfeiture to the Company in accordance with a vesting schedule to be determined by the Board.

(ii) Vesting.    Shares  of  Common  Stock  awarded  under  the  Restricted  Stock  Award  Agreement  may  be  subject  to 

(iii) Termination of Participant’s Continuous Service.  If a Participant’s Continuous Service terminates, the Company 
may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant that have 
not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award Agreement.

(iv) Transferability.  Rights to acquire shares of Common Stock under the Restricted Stock Award Agreement will be 
transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board 
will determine in its sole discretion, so long as Common Stock awarded under the Restricted Stock Award Agreement remains subject to the 
terms of the Restricted Stock Award Agreement. 

subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate.

(v)

Dividends.  A Restricted Stock Award Agreement may provide that any dividends paid on Restricted Stock will be

(b)Restricted Stock Unit Awards.  Each Restricted Stock Unit Award Agreement will be in such form and will contain such terms 
and conditions as the Board will deem appropriate.  The terms and conditions of Restricted Stock Unit Award Agreements may change from 
time to time, and the terms and conditions of separate Restricted Stock Unit Award Agreements need not be identical.  Each Restricted Stock 
Unit  Award  Agreement  will  conform  to  (through  incorporation  of  the  provisions  hereof  by  reference  in  the  Agreement  or  otherwise)  the 
substance of each of the following provisions:

(i)

Consideration.  At the time of grant of a Restricted Stock Unit Award, the Board will determine the consideration, 
if  any,  to  be  paid  by  the  Participant  upon  delivery  of  each  share  of  Common  Stock  subject  to  the  Restricted  Stock  Unit  Award.    The 
consideration to be paid (if any) by the Participant for each share of Common Stock subject to a Restricted Stock Unit Award may be paid in 
any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law.

conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate.

(ii) Vesting.  At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions on or 

7.

 
 
(iii) Payment.  A Restricted Stock Unit Award may be settled by the delivery of shares of Common Stock, their cash 
equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock 
Unit Award Agreement.

(iv) Additional  Restrictions.    At  the  time  of  the  grant  of  a  Restricted  Stock  Unit  Award,  the  Board,  as  it  deems 
appropriate,  may  impose  such  restrictions  or  conditions  that  delay  the  delivery  of  the  shares  of  Common  Stock  (or  their  cash  equivalent) 
subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award.

(v)

Dividend Equivalents.  Dividend equivalents may be credited in respect of shares of Common Stock covered by a 
Restricted  Stock  Unit  Award,  as  determined  by  the  Board  and  contained  in  the  Restricted  Stock  Unit  Award  Agreement.    At  the  sole 
discretion  of  the  Board,  such  dividend  equivalents  may  be  converted  into  additional  shares  of  Common  Stock  covered  by  the  Restricted 
Stock Unit Award in such manner as determined by the Board.  Any additional shares covered by the Restricted Stock Unit Award credited 
by reason of such dividend equivalents will be subject to all of the same terms and conditions of the underlying Restricted Stock Unit Award 
Agreement to which they relate.  

(vi) Termination  of  Participant’s  Continuous  Service.    Except  as  otherwise  provided  in  the  applicable  Restricted 
Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s 
termination of Continuous Service.

(c) Performance Awards.

(i)

Performance  Stock  Awards.    A  Performance  Stock  Award  is  an  Award  that  is  payable  (including  that  may  be 
granted,  may  vest  or  may  be  exercised)  contingent  upon  the  attainment  during  a  Performance  Period  of  certain  Performance  Goals.    A 
Performance Stock Award may, but need not, require the Participant’s completion of a specified period of Continuous Service. The length of 
any  Performance  Period,  the  Performance  Goals  to  be  achieved  during  the  Performance  Period,  and  the  measure  of  whether  and  to  what 
degree such Performance Goals have been attained will be conclusively determined by the Board or Committee, in its sole discretion.  In 
addition, to the extent permitted by applicable law and the applicable Award Agreement, the Board (or Committee, as the case may be) may 
determine that cash may be used in payment of Performance Stock Awards.

(ii) Discretion.    A  majority  of  the  Company’s  Independent  Directors  or  the  Independent  Compensation  Committee 
retains the discretion to adjust or eliminate the compensation or economic benefit due upon attainment of Performance Goals and to define 
the manner of calculating the Performance Criteria it selects to use for a Performance Period.  Partial achievement of the specified criteria 
may result in the payment or vesting corresponding to the degree of achievement as specified in the Award Agreement.

(d)Other Stock Awards.  Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common 
Stock, including the appreciation in value thereof (e.g., options or stock rights with an exercise price or strike price less than 100% of the Fair 
Market Value of the Common Stock at the time of grant) may be granted either alone or in addition to Awards provided for under Section 5 
and the preceding provisions of this Section 6.  Subject to the provisions of the Plan, a majority of the Company’s Independent Directors or 
the Independent Compensation Committee will have sole and complete authority to determine the persons to whom and the time or times at 
which  such  Other  Stock  Awards  will  be  granted,  the  number  of  shares  of  Common  Stock  (or  the  cash  equivalent  thereof)  to  be  granted 
pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock Awards.

7.

COVENANTS OF THE COMPANY.

(a)Availability  of  Shares.    The  Company  will  keep  available  at  all  times  the  number  of  shares  of  Common  Stock  reasonably 

required to satisfy then-outstanding Awards.

8.

 
 
(b)Securities Law Compliance.  The Company will seek to obtain from each regulatory commission or agency, as necessary, such 
authority  as  may  be  required  to  grant  Awards  and  to  issue  and  sell  shares  of  Common  Stock  upon  exercise  or  vesting  of  the  Awards; 
provided, however, that this undertaking will not require the Company to register under the Securities Act, or other securities or applicable 
laws,  the  Plan,  any  Award  or  any  Common  Stock  issued  or  issuable  pursuant  to  any  such  Award.    If,  after  reasonable  efforts  and  at  a 
reasonable cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company 
deems  necessary  or  advisable  for  the  lawful  issuance  and  sale  of  Common  Stock  under  the  Plan,  the  Company  will  be  relieved  from  any 
liability for failure to issue and sell Common Stock upon exercise or vesting of such Awards unless and until such authority is obtained. A 
Participant will not be eligible for the grant of an Award or the subsequent issuance of cash or Common Stock pursuant to the Award if such 
grant or issuance would be in violation of any applicable law.

(c) No Obligation to Notify or Minimize Taxes.  The Company will have no duty or obligation to any Participant to advise such 
holder as to the tax treatment or time or manner of exercising such Award.  Furthermore, the Company will have no duty or obligation to 
warn or otherwise advise such holder of a pending termination or expiration of an Award or a possible period in which the Award may not be 
exercised.  The Company has no duty or obligation to minimize the tax consequences of an Award to the holder of such Award.

8. MISCELLANEOUS.

(a)Use of Proceeds from Sales of Common Stock.  Proceeds from the sale of shares of Common Stock pursuant to Awards will 

constitute general funds of the Company.

(b)Corporate Action Constituting Grant of Awards.  Corporate action constituting a grant by the Company of an Award to any 
Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when 
the instrument, certificate, or letter evidencing the Award is communicated to, or actually received or accepted by, the Participant.  In the 
event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action constituting the grant contain 
terms (e.g., exercise price, vesting schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant 
documents  as  a  result  of  a  clerical  error  in  the  papering  of  the  Award  Agreement  or  related  grant  documents,  the  corporate  records  will 
control and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents.  

(c) Stockholder Rights.  No Participant will be deemed to be the holder of, or to have any of the rights of a holder with respect to, 
any shares of Common Stock subject to an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the 
issuance  of  shares  of  Common  Stock  under,  the  Award  pursuant  to  its  terms,  and  (ii)  the  issuance  of  the  Common  Stock  subject  to  such 
Award has been entered into the books and records of the Company.

(d)No  Employment  or  Other  Service  Rights.  Nothing  in  the  Plan,  any  Award  Agreement  or  any  other  instrument  executed 
thereunder  or  in  connection  with  any  Award  granted  pursuant  thereto  will  confer  upon  any  Participant  any  right  to  continue  to  serve  the 
Company or an Affiliate in the capacity in effect at the time the Award was granted or will affect the right of the Company or an Affiliate to 
terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to 
the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the 
Company or an Affiliate, and any applicable provisions of the corporate law of the state or foreign jurisdiction in which the Company or the 
Affiliate is domiciled or incorporated, as the case may be.

(e) Change in Time Commitment.  In the event a Participant’s regular level of time commitment in the performance of his or her 
services  for  the  Company  and  any  Affiliates  is  reduced  (for  example,  and  without  limitation,  if  the  Participant  is  an  Employee  of  the 
Company  and  the  Employee  has  a  change  in  status  from  a  full-time  Employee  to  a  part-time  Employee  or  takes  an  extended  leave  of 
absence) after the date of grant of any Award to the Participant, the Board has the right in its sole discretion to (x) make a corresponding 
reduction in the number of shares or cash amount subject to any portion of such Award that is scheduled to vest or become payable after the 
date of such change 

9.

 
 
in time commitment, and (y) in lieu of or in combination with such a reduction, extend the vesting or payment schedule applicable to such 
Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or 
extended. 

(f) Investment Assurances.    The  Company  may  require  a  Participant,  as  a  condition  of  exercising  or  acquiring  Common  Stock 
under any Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and 
business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced 
in financial and business matters and that such Participant is capable of evaluating, alone or together with the purchaser representative, the 
merits  and  risks  of  exercising  the  Award;  and  (ii)  to  give  written  assurances  satisfactory  to  the  Company  stating  that  the  Participant  is 
acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise 
distributing the Common Stock.  The foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if 
(A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Award has been registered under a then currently 
effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the 
Company that such requirement need not be met in the circumstances under the then applicable securities laws.  The Company may, upon 
advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate 
in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

(g)Withholding Obligations.  Unless prohibited by the terms of an Award Agreement, the Company may, in its sole discretion, 
satisfy any federal, state or local tax withholding obligation relating to an Award by any of the following means or by a combination of such 
means: (i) causing the Participant to tender a cash payment; (ii)  withholding shares of Common Stock from the shares of Common Stock 
issued  or  otherwise  issuable  to  the  Participant  in  connection  with  the  Award;  provided,  however,  that  no  shares  of  Common  Stock  are 
withheld with a value exceeding the maximum amount of tax required to be withheld by law (or such lesser amount as may be necessary to 
avoid classification of the Award as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash; (iv) 
withholding payment from any amounts otherwise payable to the Participant; or (v) by such other method as may be set forth in the Award 
Agreement.

(h)Electronic  Delivery.    Any  reference  herein  to  a  “written”  agreement  or  document  will  include  any  agreement  or  document 
delivered  electronically,  filed  publicly  at  www.sec.gov  (or  any  successor  website  thereto)  or  posted  on  the  Company’s  intranet  (or  other 
shared electronic medium controlled by the Company to which the Participant has access).

(i) Deferrals.    To  the  extent  permitted  by  applicable  law,  the  Board,  in  its  sole  discretion,  may  determine  that  the  delivery  of 
Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may 
establish programs and procedures for deferral elections to be made by Participants.  Deferrals by Participants will be made in accordance 
with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is still 
an employee or otherwise providing services to the Company.  The Board is authorized to make deferrals of Awards and determine when, and 
in  what  annual  percentages,  Participants  may  receive  payments,  including  lump  sum  payments,  following  the  Participant’s  termination  of 
Continuous  Service,  and  implement  such  other  terms  and  conditions  consistent  with  the  provisions  of  the  Plan  and  in  accordance  with 
applicable law.

(j) Compliance with Section 409A of the Code.  Unless otherwise expressly provided for in an Award Agreement, the Plan and 
Award  Agreements  will  be  interpreted  to  the  greatest  extent  possible  in  a  manner  that  makes  the  Plan  and  the  Awards  granted  hereunder 
exempt  from  Section  409A  of  the  Code,  and,  to  the  extent  not  so  exempt,  in  compliance  with  Section  409A  of  the  Code.    If  the  Board 
determines that any Award granted hereunder is not exempt from and is therefore subject to Section 409A of the Code, the Award Agreement 
evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the 
Code, and to the extent an Award Agreement is silent on terms necessary for compliance, such terms are hereby incorporated by reference 
into the Award Agreement.  Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides 
otherwise), if the shares of Common Stock are publicly traded, 

10.

 
 
and if a Participant holding an Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for 
purposes  of  Section  409A  of  the  Code,  no  distribution  or  payment  of  any  amount  that  is  due  because  of  a  “separation  from  service”  (as 
defined in Section 409A of the Code without regard to alternative definitions thereunder) will be issued or paid before the date that is six 
months  following  the  date  of  such  Participant’s  “separation  from  service”  (as  defined  in  Section  409A  of  the  Code  without  regard  to 
alternative  definitions  thereunder)  or,  if  earlier,  the  date  of  the  Participant’s  death,  unless  such  distribution  or  payment  can  be  made  in  a 
manner that complies with Section 409A of the Code, and any amounts so deferred will be paid in a lump sum on the day after such six 
month period elapses, with the balance paid thereafter on the original schedule.  

(k)Clawback/Recovery.  All Awards granted under the Plan will be subject to recoupment in accordance with any clawback policy 
that  the  Company  is  required  to  adopt  pursuant  to  the  listing  standards  of  any  national  securities  exchange  or  association  on  which  the 
Company’s  securities  are  listed  or  as  is  otherwise  required  by  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act  or  other 
applicable law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the 
Board  determines  necessary  or  appropriate,  including  but  not  limited  to  a  reacquisition  right  in  respect  of  previously  acquired  shares  of 
Common Stock or other cash or property upon the occurrence of an event constituting Cause. No recovery of compensation under such a 
clawback policy will be an event giving rise to a right to resign for “good reason” or “constructive termination” (or similar term) under any
agreement with the Company.

9.

ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS.

(a)Capitalization Adjustments.    In  the  event  of  a  Capitalization  Adjustment,  the  Board  will  appropriately  and  proportionately 
adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a); and (ii) the class(es) and number of 
securities and price per share of stock subject to outstanding Awards.  The Board will make such adjustments, and its determination will be 
final, binding and conclusive.

(b)Dissolution.    Except  as  otherwise  provided  in  the  Award  Agreement,  in  the  event  of  a  Dissolution  of  the  Company,  all 
outstanding Awards (other than Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or 
the Company’s right of repurchase) will terminate immediately prior to the completion of such Dissolution, and the shares of Common Stock 
subject  to  the  Company’s  repurchase  rights  or  subject  to  a  forfeiture  condition  may  be  repurchased  or  reacquired  by  the  Company 
notwithstanding the fact that the holder of such Award is providing Continuous Service; provided, however, that the Board may, in its sole 
discretion, cause some or all Awards to become fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent 
such Awards have not previously expired or terminated) before the Dissolution is completed but contingent on its completion.

(c) Transaction.    The  following  provisions  shall  apply  to  Awards  in  the  event  of  a  Transaction  unless  otherwise  provided  in  the 
instrument  evidencing  the  Award  or  any  other  written  agreement  between  the  Company  or  any  Affiliate  and  the  Participant  or  unless 
otherwise expressly provided by the Board at the time of grant of an Award.  In the event of a Transaction, then, notwithstanding any other 
provision  of  the  Plan,  the  Board  shall  take  one  or  more  of  the  following  actions  with  respect  to  Awards,  contingent  upon  the  closing  or 
completion of the Transaction:

arrange  for  the  surviving  corporation  or  acquiring  corporation  (or  the  surviving  or  acquiring  corporation’s  parent 
company) to assume or continue the Award or to substitute a similar stock award for the Award (including, but not limited to, an award to 
acquire the same consideration paid to the stockholders of the Company pursuant to the Transaction);

(i)

arrange for the assignment of any reacquisition or repurchase rights held by the Company in respect of Common 
Stock issued pursuant to the Award to the surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent 
company);

(ii)

exercised) to a date prior to the effective time of such Transaction as the Board shall determine 

(iii)

accelerate the vesting, in whole or in part, of the Award (and, if applicable, the time at which the Award may be 

11.

 
 
(or, if the Board shall not determine such a date, to the date that is five days prior to the effective date of the Transaction), with such Award 
terminating if not exercised (if applicable) at or prior to the effective time of the Transaction;

respect to the Award;

(iv)

arrange  for  the  lapse,  in  whole  or  in  part,  of  any  reacquisition  or  repurchase  rights  held  by  the  Company  with 

time of the Transaction, in exchange for such cash consideration, if any, as the Board, in its sole discretion, may consider appropriate; and

(v)

cancel or arrange for the cancellation of the Award, to the extent not vested or not exercised prior to the effective 

(vi) make a payment, in such form as may be determined by the Board equal to the excess, if any, of (A) the value of the 
property the Participant would have received upon the exercise of the Award immediately prior to the effective time of the Transaction, over 
(B) any exercise price payable by such holder in connection with such exercise.  For clarity, this payment may be zero ($0) if the value of the 
property  is  equal  to  or  less  than  the  exercise  price.    Payments  under  this  provision  may  be  delayed  to  the  same  extent  that  payment  of 
consideration to the holders of Common Stock in connection with the Transaction is delayed as a result of escrows, earn outs, holdbacks or 
other contingencies.

The Board need not take the same action or actions with respect to all Awards or portions thereof or with respect to all Participants. 

The Board may take different actions with respect to the vested and unvested portions of an Award.

(d)Change in Control.  An Award may be subject to additional acceleration of vesting and exercisability upon or after a Change in 
Control  as  may  be  provided  in  the  Award  Agreement  for  such  Award  or  as  may  be  provided  in  any  other  written  agreement  between  the 
Company or any Affiliate and the Participant.

10. TERMINATION OR SUSPENSION OF THE PLAN.

The Board may suspend or terminate the Plan at any time. No Awards may be granted under the Plan while the Plan is suspended or 

after it is terminated.

11. EFFECTIVE DATE OF THE PLAN.

The Plan will come into existence on the Effective Date.

12. CHOICE OF LAW.

The  law  of  the  State  of  Delaware  will  govern  all  questions  concerning  the  construction,  validity  and  interpretation  of  this  Plan, 

without regard to that state’s conflict of laws rules.

13. DEFINITIONS.  As used in the Plan, the following definitions will apply to the capitalized terms indicated below:

(a)“Affiliate” means, at the time of determination, any “parent” or “subsidiary” of the Company as such terms are defined in Rule 
405  of  the  Securities  Act.    The  Board  will  have  the  authority  to  determine  the  time  or  times  at  which  “parent”  or  “subsidiary”  status  is 
determined within the foregoing definition.

(b)“Award” means an Option, a Stock Appreciation Right, a Restricted Stock Award, a Restricted Stock Unit Award, a Performance 

Stock Award or an Other Stock Award.

(c) “Award Agreement” means a written agreement between the Company and a Participant evidencing the terms and conditions of 

an Award.

12.

 
 
(d)“Board” means the Board of Directors of the Company.

(e) “Capitalization Adjustment” means any change that is made in, or other events that occur with respect to, the Common Stock 
subject to the Plan or subject to any Award after the Effective Date without the receipt of consideration by the Company through merger, 
consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash
dividend, stock split, reverse stock split liquidating dividend, combination of shares, exchange of shares, change in corporate structure or any 
similar  equity  restructuring  transaction,  as  that  term  is  used  in  Statement  of  Financial  Accounting  Standards  Board  Accounting  Standards 
Codification  Topic  718  (or  any  successor  thereto).    Notwithstanding  the  foregoing,  the  conversion  of  any  convertible  securities  of  the 
Company will not be treated as a Capitalization Adjustment.

(f) “Cause”  shall  have  the  meaning  ascribed  to  such  term  in  any  written  agreement  between  the  Participant  and  the  Company 
defining  such  term  and,  in  the  absence  of  such  agreement,  such  term  means,  with  respect  to  a  Participant,  the  occurrence  of  any  of  the 
following events:  (i) such Participant’s commission of any felony or any crime involving fraud, dishonesty or moral turpitude under the laws 
of  the  United  States  or  any  state  thereof;  (ii)  such  Participant’s  attempted  commission  of,  or  participation  in,  a  fraud  or  act  of  dishonesty 
against  the  Company;  (iii)  such  Participant’s  intentional,  material  violation  of  any  contract  or  agreement  between  the  Participant  and  the 
Company or of any statutory duty owed to the Company; (iv) such Participant’s unauthorized use or disclosure of the Company’s confidential 
information or trade secrets; or (v) such Participant’s gross misconduct. The determination that a termination of the Participant’s Continuous 
Service is either for Cause or without Cause shall be made by the Company, in its sole discretion.  Any determination by the Company that 
the  Continuous  Service  of  a  Participant  was  terminated  with  or  without  Cause  for  the  purposes  of  outstanding  Awards  held  by  such 
Participant shall have no effect upon any determination of the rights or obligations of the Company or such Participant for any other purpose.

(g)“Change in Control” means the occurrence, in a single transaction or in a series of related transactions, of any one or more of 

the following events:

(i)

any  Exchange  Act  Person  becomes  the  Owner,  directly  or  indirectly,  of  securities  of  the  Company  representing 
more than 50% of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or 
similar transaction.  Notwithstanding the foregoing, a Change in Control will not be deemed to occur (A) on account of the acquisition of 
securities of the Company directly from the Company, (B) on account of the acquisition of securities of the Company by an investor, any 
affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions the 
primary purpose of which is to obtain financing for the Company through the issuance of equity securities, (C) on account of the acquisition 
of securities of the Company by any individual who is, on the IPO Date, either an executive officer or a Director (either, an “IPO Investor”) 
and/or any entity in which an IPO Investor has a direct or indirect interest (whether in the form of voting rights or participation in profits or 
capital contributions) of more than 50% (collectively, the “IPO Entities”) or on account of the IPO Entities continuing to hold shares that 
come to represent more than 50% of the combined voting power of the Company’s then outstanding securities as a result of the conversion of 
any class of the Company’s securities into another class of the Company’s securities having a different number of votes per share pursuant to 
the conversion provisions set forth in the Company’s Amended and Restated Certificate of Incorporation; or (D) solely because the level of 
Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting 
securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, 
provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by 
the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the 
repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject
Person over the designated percentage threshold, then a Change in Control will be deemed to occur;

(ii)

there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company 
and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately
prior  thereto  do  not  Own,  directly  or  indirectly,  either  (A)  outstanding  voting  securities  representing  more  than  50%  of  the  combined

Entity in such merger, consolidation or similar transaction or (B) more than 50% of the combined outstanding voting power of the parent of 
the  surviving  Entity  in  such  merger,  consolidation  or  similar  transaction,  in  each  case  in  substantially  the  same  proportions  as  their 
Ownership  of  the  outstanding  voting  securities  of  the  Company  immediately  prior  to  such  transaction;  provided, however,  that  a  merger, 
consolidation  or  similar  transaction  will  not  constitute  a  Change  in  Control  under  this  prong  of  the  definition  if  the  outstanding  voting 
securities representing more than 50% of the combined voting power of the surviving Entity or its parent are owned by the IPO Entities;

(iii)

there  is  consummated  a  sale,  lease,  exclusive  license  or  other  disposition  of  all  or  substantially  all  of  the 
consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the 
consolidated assets of the Company and its Subsidiaries to an Entity, more than 50% of the combined voting power of the voting securities of 
which  are  Owned  by  stockholders  of  the  Company  in  substantially  the  same  proportions  as  their  Ownership  of  the  outstanding  voting 
securities of the Company immediately prior to such sale, lease, license or other disposition; provided, however, that a sale, lease, exclusive 
license  or  other  disposition  of  all  or  substantially  all  of  the  consolidated  assets  of  the  Company  and  its  Subsidiaries  will  not  constitute  a 
Change in Control under this prong of the definition if the outstanding voting securities representing more than 50% of the combined voting 
power of the acquiring Entity or its parent are owned by the IPO Entities;

Company, or a complete dissolution or liquidation of the Company will otherwise occur, except for a liquidation into a parent corporation; or

nomination  for  election)  of  any  new  Board  member  was  approved  or  recommended  by  a  majority  vote  of  the  members  of  the  Incumbent 
Board then still in office, such new member will, for purposes of this Plan, be considered as a member of the Incumbent Board.

Notwithstanding the foregoing definition or any other provision of the Plan, the term Change in Control will not include a sale of 
assets,  merger  or  other  transaction  effected  exclusively  for  the  purpose  of  changing  the  domicile  of  the  Company  and  the  definition  of 
Change in Control (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant will

3. NUMBER  OF  SHARES.    The  number  of  Restricted  Stock  Units  subject  to  your  Award  may  be  adjusted  from  time  to  time  for 
Capitalization  Adjustments,  as  provided  in  the  Plan.  Any  additional  Restricted  Stock  Units,  shares,  cash  or  other  property  that  becomes 
subject  to  the  Award  pursuant  to  this  Section  3,  if  any,  shall  be  subject,  in  a  manner  determined  by  the  Board,  to  the  same  forfeiture 
restrictions,  restrictions  on  transferability,  and  time  and  manner  of  delivery  as  applicable  to  the  other  Restricted  Stock  Units  and  shares 
covered  by  your  Award.  Notwithstanding  the  provisions  of  this  Section  3,  no  fractional  shares  or  rights  for  fractional  shares  of  Common 
Stock shall be created pursuant to this Section 3. Any fraction of a share will be rounded down to the nearest whole share.

4. SECURITIES LAW COMPLIANCE.  You may not be issued any Common Stock under your Award unless the shares of Common Stock 
underlying the Restricted Stock Units are either (i) then registered under the Securities Act, or (ii) the Company has determined that such 
issuance would be exempt from the registration requirements of the Securities Act. Your Award must also comply with other applicable laws 
and regulations governing the Award, and you shall not receive such Common Stock if the Company determines that such receipt would not 
be in material compliance with such laws and regulations.

5. TRANSFER RESTRICTIONS.    Prior  to  the  time  that  shares  of  Common  Stock  have  been  delivered  to  you,  you  may  not  transfer, 
pledge, sell or otherwise dispose of this Award or the shares issuable in respect of your Award, except as expressly provided in this Section 5. 
For example, you may not use shares that may be issued in respect of your Restricted Stock Units as security for a loan. The restrictions on 
transfer set forth herein will lapse upon delivery to you of shares in respect of your vested Restricted Stock Units.

Death.  Your Award is transferable by will and by the laws of descent and distribution. At your death, vesting of 
your Award will cease and your executor or administrator of your estate shall be entitled to receive, on behalf of your estate, any Common 
Stock or other consideration that vested but was not issued before your death. 

(a)

(b) Domestic Relations Orders.  Upon receiving written permission from the Board or its duly authorized designee, 
and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your 
right to receive the distribution of Common Stock or other consideration hereunder, pursuant to a domestic relations order, marital settlement 
agreement or other divorce or separation instrument as permitted by applicable law that contains the information required by the Company to 
effectuate the transfer. You are encouraged to discuss the proposed terms of any division of this Award with the Company General Counsel
prior to finalizing the domestic relations order or marital settlement agreement to verify that you may make such transfer, and if so, to help 
ensure the required information is contained within the domestic relations order or marital settlement agreement.  

6. DATE OF ISSUANCE. 

(a)

The  issuance  of  shares  in  respect  of  the  Restricted  Stock  Units  is  intended  to  comply  with  Treasury  Regulations 
Section 1.409A-1(b)(4) and will be construed and administered in such a manner.  Subject to the satisfaction of the Withholding Obligation 
set forth in Section 11 of this Agreement, in the event one or more Restricted Stock Units vests, the Company shall issue to you one (1) share 
of  Common  Stock  for  each  Restricted  Stock  Unit  that  vests  on  the  applicable  vesting  date(s)  (subject  to  any  adjustment  under  Section  3 
above,  and  subject  to  any  different  provisions  in  the  Grant  Notice).  Each  issuance  date  determined  by  this  paragraph  is  referred  to  as  an 
“Original Issuance Date”. 

(b)
following business day. In addition, if:

If  the  Original  Issuance  Date  falls  on  a  date  that  is  not  a  business  day,  delivery  shall  instead  occur  on  the  next 

(i) the  Original  Issuance  Date  does  not  occur  (1)  during  an  “open  window  period”  applicable  to  you,  as 
determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when 
you are otherwise permitted to sell shares of Common Stock on an established stock exchange or stock market (including but not limited to 
under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the Exchange Act and was entered into 
in compliance with the Company's policies (a “10b5-1 Arrangement”)), and 

(ii) either  (1)  a  Withholding  Obligation  does  not  apply,  or  (2)  the  Company  decides,  prior  to  the  Original 
Issuance Date, (A) not to satisfy the Withholding Obligation by withholding shares of Common Stock from the shares otherwise due, on the 
Original Issuance Date, to you under this Award, and (B) not to permit you to enter into a “same day sale” commitment with a broker-dealer 
pursuant to Section 11 of this Agreement (including but not limited to a commitment under a 10b5-1 Arrangement) and (C) not to permit you 
to pay your Withholding Obligation in cash, 

then the shares that would otherwise be issued to you on the Original Issuance Date will not be delivered on such Original Issuance 
Date  and  will  instead  be  delivered  on  the  first  business  day  when  you  are  not  prohibited  from  selling  shares  of  the  Company’s  Common 
Stock in the open public market, but in no event later than December 31 of the calendar year in which the Original Issuance Date occurs (that 
is, the last day of your taxable year in which the Original Issuance Date occurs), or, if and only if permitted in a manner that complies with 
Treasury Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month of the applicable year 
following the year in which the shares of Common Stock under this Award are no longer subject to a “substantial risk of forfeiture” within 
the meaning of Treasury Regulations Section 1.409A-1(d).

Company. 

(c)

The form of delivery (e.g., a stock certificate or electronic entry evidencing such shares) shall be determined by the 

2

 
 
7. DIVIDENDS.  You shall receive no benefit or adjustment to your Award with respect to any cash dividend, stock dividend or other 
distribution that does not result from a Capitalization Adjustment; provided, however, that this sentence will not apply with respect to any 
shares of Common Stock that are delivered to you in connection with your Award after such shares have been delivered to you.

8. RESTRICTIVE LEGENDS.  The shares of Common Stock issued in respect of your Award shall be endorsed with appropriate legends 

as determined by the Company.

9. EXECUTION OF DOCUMENTS.  You hereby acknowledge and agree that the manner selected by the Company by which you indicate 
your consent to your Grant Notice is also deemed to be your execution of your Grant Notice and of this Agreement. You further agree that 
such manner of indicating consent may be relied upon as your signature for establishing your execution of any documents to be executed in 
the future in connection with your Award.

10.AWARD NOT A SERVICE CONTRACT. 

(a)

Nothing in this Agreement (including, but not limited to, the vesting of your Award or the issuance of the shares in 
respect of your Award), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan 
shall: (i) confer upon you any right to continue in the employ or service of, or affiliation with, the Company or an Affiliate; (ii) constitute any 
promise  or  commitment  by  the  Company  or  an  Affiliate  regarding  the  fact  or  nature  of  future  positions,  future  work  assignments,  future 
compensation or any other term or condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan 
unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or (iv) deprive the Company of the right to 
terminate you at will and without regard to any future vesting opportunity that you may have. 

(b)

By accepting this Award, you acknowledge and agree that the right to continue vesting in the Award pursuant to the 
vesting schedule provided in the Grant Notice may not be earned unless (in addition to any other conditions described in the Grant Notice 
and this Agreement) you continue as an employee, director or consultant at the will of the Company and affiliate, as applicable (not through 
the act of being hired, being granted this Award or any other award or benefit) and that the Company has the right to reorganize, sell, spin-out 
or  otherwise  restructure  one  or  more  of  its  businesses  or  Affiliates  at  any  time  or  from  time  to  time,  as  it  deems  appropriate  (a 
“reorganization”). You acknowledge and agree that such a reorganization could result in the termination of your Continuous Service, or the
termination of Affiliate status of your employer and the loss of benefits available to you under this Agreement, including but not limited to, 
the  termination  of  the  right  to  continue  vesting  in  the  Award.  You  further  acknowledge  and  agree  that  this  Agreement,  the  Plan,  the 
transactions  contemplated  hereunder  and  the  vesting  schedule  set  forth  herein  or  any  covenant  of  good  faith  and  fair  dealing  that  may  be 
found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant for the 
term of this Agreement, for any period, or at all, and shall not interfere in any way with the Company’s right to terminate your Continuous 
Service at any time, with or without your cause or notice, or to conduct a reorganization.

11.WITHHOLDING OBLIGATION.

(a)  On each vesting date, and on or before the time you receive a distribution of the shares of Common Stock in respect 
of your Restricted Stock Units, and at any other time as reasonably requested by the Company in accordance with applicable tax laws, you 
hereby  authorize  any  required  withholding  from  the  Common  Stock  issuable  to  you  and/or  otherwise  agree  to  make  adequate  provision, 
including in cash, for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any 
Affiliate that arise in connection with your Award (the “Withholding Obligation”).  

(b)  By accepting this Award, you acknowledge and agree that the Company or any Affiliate may, in its sole discretion, 
satisfy  all  or  any  portion  of  the  Withholding  Obligation  relating  to  your  Restricted  Stock  Units  by  any  of  the  following  means  or  by  a 
combination  of  such  means:  (i)  causing  you  to  pay  any  portion  of  the  Withholding  Obligation  in  cash;  (ii)  withholding  from  any
compensation otherwise payable to you by the Company; 

3

 
 
(iii)  withholding  shares  of  Common  Stock  from  the  shares  of  Common  Stock  issued  or  otherwise  issuable  to  you  in  connection  with  the 
Award with a Fair Market Value (measured as of the date shares of Common Stock are issued pursuant to Section 6) equal to the amount of 
such Withholding Obligation; provided, however, that the number of such shares of Common Stock so withheld will not exceed the amount 
necessary  to  satisfy  the  Withholding  Obligation  using  the  maximum  statutory  withholding  rates  for  federal,  state,  local  and  foreign  tax 
purposes, including payroll taxes, that are applicable to supplemental taxable income; and provided, further, that to the extent necessary to 
qualify  for  an  exemption  from  application  of  Section  16(b)  of  the  Exchange  Act,  if  applicable,  such  share  withholding  procedure  will  be 
subject to the express prior approval of the Board or the Company’s Compensation Committee; and/or (iv) permitting or requiring you to 
enter into a “same day sale” commitment, if applicable, with a broker-dealer that is a member of the Financial Industry Regulatory Authority 
(a “FINRA Dealer”), pursuant to this authorization and without further consent,  whereby you irrevocably elect to sell a portion of the shares 
to  be  delivered  in  connection  with  your  Restricted  Stock  Units  to  satisfy  the  Withholding  Obligation  and  whereby  the  FINRA  Dealer 
irrevocably commits to forward the proceeds necessary to satisfy the Withholding Obligation directly to the Company and/or its Affiliates. 
Unless  the  Withholding  Obligation  is  satisfied,  the  Company  shall  have  no  obligation  to  deliver  to  you  any  Common  Stock  or  any  other 
consideration pursuant to this Award.

(c)  In the event the Withholding Obligation arises prior to the delivery to you of Common Stock or it is determined after 
the delivery of Common Stock to you that the amount of the Withholding Obligation was greater than the amount withheld by the Company, 
you agree to indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount.

12.TAX CONSEQUENCES.  The Company has no duty or obligation to minimize the tax consequences to you of this Award and shall 
not be liable to you for any adverse tax consequences to you arising in connection with this Award. You are hereby advised to consult with 
your own personal tax, financial and/or legal advisors regarding the tax consequences of this Award and by signing the Grant Notice, you 
have agreed that you have done so or knowingly and voluntarily declined to do so. You understand that you (and not the Company) shall be 
responsible for your own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 

13.UNSECURED  OBLIGATION.    Your  Award  is  unfunded,  and  as  a  holder  of  a  vested  Award,  you  shall  be  considered  an  unsecured 
creditor of the Company with respect to the Company’s obligation, if any, to issue shares or other property pursuant to this Agreement. You 
shall not have voting or any other rights as a stockholder of the Company with respect to the shares to be issued pursuant to this Agreement 
until such shares are issued to you pursuant to Section 6 of this Agreement. Upon such issuance, you will obtain full voting and other rights 
as  a  stockholder  of  the  Company.  Nothing  contained  in  this  Agreement,  and  no  action  taken  pursuant  to  its  provisions,  shall  create  or  be 
construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person. 

14.NOTICES.  Any notice or request required or permitted hereunder shall be given in writing (including electronically) and will be 
deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the 
United  States  mail,  postage  prepaid,  addressed  to  you  at  the  last  address  you  provided  to  the  Company.  The  Company  may,  in  its  sole 
discretion, decide to deliver any documents related to participation in the Plan and this Award by electronic means or to request your consent 
to participate in the Plan by electronic means. By accepting this Award, you consent to receive such documents by electronic delivery and to 
participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated 
by the Company.

15.HEADINGS.    The  headings  of  the  Sections  in  this  Agreement  are  inserted  for  convenience  only  and  shall  not  be  deemed  to 

constitute a part of this Agreement or to affect the meaning of this Agreement.

16.MISCELLANEOUS.

(a)

The rights and obligations of the Company under your Award shall be transferable by the 

4

 
 
Company to any one or more persons or entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable 
by, the Company’s successors and assigns. 

determination of the Company to carry out the purposes or intent of your Award.

(b) You  agree  upon  request  to  execute  any  further  documents  or  instruments  necessary  or  desirable  in  the  sole 

the advice of counsel prior to executing and accepting your Award and fully understand all provisions of your Award.

(c)

You acknowledge and agree that you have reviewed your Award in its entirety, have had an opportunity to obtain 

governmental agencies or national securities exchanges as may be required.

(d)

This  Agreement  shall  be  subject  to  all  applicable  laws,  rules,  and  regulations,  and  to  such  approvals  by  any 

All  obligations  of  the  Company  under  the  Plan  and  this  Agreement  shall  be  binding  on  any  successor  to  the 
Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or 
substantially all of the business and/or assets of the Company.

(e)

17.GOVERNING PLAN DOCUMENT.  Your Award is subject to all the provisions of the Plan, the provisions of which are hereby made a 
part  of  your  Award,  and  is  further  subject  to  all  interpretations,  amendments,  rules  and  regulations  which  may  from  time  to  time  be 
promulgated  and  adopted  pursuant  to  the  Plan.  Your  Award  (and  any  compensation  paid  or  shares  issued  under  your  Award)  is  subject  to 
recoupment  in  accordance  with  The  Dodd–Frank  Wall  Street  Reform  and  Consumer  Protection  Act  and  any  implementing  regulations 
thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable law. No 
recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntarily terminate employment upon a 
resignation for “good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company.

18.EFFECT  ON  OTHER  EMPLOYEE  BENEFIT  PLANS.    The  value  of  the  Award  subject  to  this  Agreement  shall  not  be  included  as 
compensation, earnings, salaries, or other similar terms used when calculating benefits under any employee benefit plan (other than the Plan) 
sponsored by the Company or any Affiliate except as such plan otherwise expressly provides. The Company expressly reserves its rights to 
amend, modify, or terminate any or all of the employee benefit plans of the Company or any Affiliate.

19.SEVERABILITY.  If all or any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful 
or  invalid,  such  unlawfulness  or  invalidity  shall  not  invalidate  any  portion  of  this  Agreement  or  the  Plan  not  declared  to  be  unlawful  or 
invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a 
manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid.

20.OTHER DOCUMENTS. You hereby acknowledge receipt or the right to receive a document providing the information required by 
Rule  428(b)(1)  promulgated  under  the  Securities  Act.  In  addition,  you  acknowledge  receipt  of  the  Company’s  policy  permitting  certain 
individuals to sell shares only during certain "window" periods and the Company's insider trading policy, in effect from time to time. 

21.AMENDMENT.  This Agreement may not be modified, amended or terminated except by an instrument in writing, signed by you 
and  by  a  duly  authorized  representative  of  the  Company.  Notwithstanding  the  foregoing,  this  Agreement  may  be  amended  solely  by  the 
Board by a writing which specifically states that it is amending this Agreement, so long as a copy of such amendment is delivered to you, and 
provided that, except as otherwise expressly provided in the Plan, no such amendment materially adversely affecting your rights hereunder 
may be made without your written consent. Without limiting the foregoing, the Board reserves the right to change, by written notice to you, 
the provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the Award as a result of any 
change in applicable laws or regulations or any future law, regulation, 

5

 
 
ruling, or judicial decision, provided that any such change shall be applicable only to rights relating to that portion of the Award which is then 
subject to restrictions as provided herein. 

22.COMPLIANCE WITH SECTION 409A OF THE CODE.  This Award is intended to be exempt from the application of Section 409A of the 
Code,  including  but  not  limited  to  by  reason  of  complying  with  the  “short-term  deferral”  rule  set  forth  in  Treasury  Regulation  Section 
1.409A-1(b)(4) and any ambiguities herein shall be interpreted accordingly.  Notwithstanding the foregoing, if it is determined that the Award 
fails to satisfy the requirements of the short-term deferral rule and is otherwise not exempt from, and determined to be deferred compensation 
subject  to  Section  409A  of  the  Code,  this  Award  shall  comply  with  Section  409A  to  the  extent  necessary  to  avoid  adverse  personal  tax 
consequences and any ambiguities herein shall be interpreted accordingly.  If it is determined that the Award is deferred compensation subject 
to Section 409A and you are a “Specified Employee” (within the meaning set forth in Section 409A(a)(2)(B)(i) of the Code) as of the date of 
your  “Separation from Service” (as defined in Section 409A), then the issuance of any shares that would otherwise be made upon the date of 
your Separation from Service or within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will instead 
be issued in a lump sum on the date that is six (6) months and one day after the date of the Separation from Service, with the balance of the 
shares issued thereafter in accordance with the original vesting and issuance schedule set forth above, but if and only if such delay in the 
issuance of the shares is necessary to avoid the imposition of adverse taxation on you in respect of the shares under Section 409A of the 
Code.  Each  installment  of  shares  that  vests  is  intended  to  constitute  a  “separate  payment”  for  purposes  of  Treasury  Regulation  Section 
1.409A-2(b)(2).

ATTACHMENT I

PERSONALIS, INC.

OPTION AGREEMENT
(2020 INDUCEMENT PLAN)
(NONSTATUTORY STOCK OPTION)

Pursuant to your Stock Option Grant Notice (“Grant Notice”) and this Option Agreement, Personalis, Inc. (the “Company”)  has 
granted  you  an  option  under  its  2020  Inducement  Plan  (the  “Plan”)  to  purchase  the  number  of  shares  of  the  Company’s  Common  Stock 
indicated in your Grant Notice at the exercise price indicated in your Grant Notice.  The option is granted to you effective as of the date of 
grant set forth in the Grant Notice (the “Date of Grant”).  The option is granted in compliance with Nasdaq Listing Rule 5635(c)(4) as a 
material inducement to you entering into employment with the Company.  If there is any conflict between the terms in this Option Agreement 
and the Plan, the terms of the Plan will control. Capitalized terms not explicitly defined in this Option Agreement or in the Grant Notice but 
defined in the Plan will have the same definitions as in the Plan.

The details of your option, in addition to those set forth in the Grant Notice and the Plan, are as follows:

1. VESTING.  Subject to the provisions contained herein, your option will vest as provided in your Grant Notice.  Vesting will cease 

upon the termination of your Continuous Service.

2. NUMBER OF SHARES AND EXERCISE PRICE.  The number of shares of Common Stock subject to your option and your exercise price 

per share in your Grant Notice will be adjusted for Capitalization Adjustments.

3. EXERCISE RESTRICTION FOR NON-EXEMPT EMPLOYEES.  If you are an Employee eligible for overtime compensation under the Fair 
Labor Standards Act of 1938, as amended (that is, a “Non-Exempt Employee”), and except as otherwise provided in the Plan, you may not 
exercise your option until you have completed at least six (6) months of Continuous Service measured from the Date of Grant, even if you 
have already been an employee for more than six (6) months. Consistent with the provisions of the Worker Economic Opportunity Act, you 
may exercise your option as to any vested portion prior to such six (6) month anniversary in the case of (i) your 

2

 
 
 
 
 
death or disability, (ii) a Corporate Transaction in which your option is not assumed, continued or substituted, (iii) a Change in Control or (iv) 
your termination of Continuous Service on your “retirement” (as defined in the Company’s benefit plans).  

4. METHOD OF PAYMENT.  You must pay the full amount of the exercise price for the shares you wish to exercise.  You may pay the 
exercise  price  in  cash  or  by  check,  bank  draft  or  money  order  payable  to  the  Company  or  in  any  other  manner  permitted  by  your  Grant 
Notice, which may include one or more of the following:

(a)

Provided that at the time of exercise the Common Stock is publicly traded, pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash 
(or  check)  by  the  Company  or  the  receipt  of  irrevocable  instructions  to  pay  the  aggregate  exercise  price  to  the  Company  from  the  sales 
proceeds.  This manner of payment is also known as a “broker-assisted exercise”, “same day sale”, or “sell to cover”.

(b)

Provided that at the time of exercise the Common Stock is publicly traded, by delivery to the Company (either by 
actual delivery or attestation) of already-owned shares of Common Stock that are owned free and clear of any liens, claims, encumbrances or 
security interests, and that are valued at Fair Market Value on the date of exercise.  “Delivery” for these purposes, in the sole discretion of the 
Company  at  the  time  you  exercise  your  option,  will  include  delivery  to  the  Company  of  your  attestation  of  ownership  of  such  shares  of 
Common Stock in a form approved by the Company.  You may not exercise your option by delivery to the Company of Common Stock if 
doing so would violate the provisions of any law, regulation or agreement restricting the redemption of the Company’s stock.

(c)

Subject to the consent of the Company at the time of exercise, by a “net exercise” arrangement pursuant to which 
the Company will reduce the number of shares of Common Stock issued upon exercise of your option by the largest whole number of shares 
with a Fair Market Value that does not exceed the aggregate exercise price.  You must pay any remaining balance of the aggregate exercise 
price not satisfied by the “net exercise” in cash or other permitted form of payment.  Shares of Common Stock will no longer be outstanding 
under your option and will not be exercisable thereafter if those shares (i) are used to pay the exercise price pursuant to the “net exercise,” (ii) 
are delivered to you as a result of such exercise, and (iii) are withheld to satisfy your tax withholding obligations.

5. WHOLE SHARES.  You may exercise your option only for whole shares of Common Stock.

6. SECURITIES  LAW  COMPLIANCE.    In  no  event  may  you  exercise  your  option  unless  the  shares  of  Common  Stock  issuable  upon 
exercise are then registered under the Securities Act or, if not registered, the Company has determined that your exercise and the issuance of 
the shares would be exempt from the registration requirements of the Securities Act.  The exercise of your option also must comply with all 
other  applicable  laws  and  regulations  governing  your  option,  and  you  may  not  exercise  your  option  if  the  Company  determines  that  such 
exercise would not be in material compliance with such laws and regulations (including any restrictions on exercise required for compliance 
with Treas. Reg. 1.401(k)-1(d)(3), if applicable).

7. TERM.  You may not exercise your option before the Date of Grant or after the expiration of the option’s term.  The term of your 

option expires, subject to the provisions of Section 5(h) of the Plan, upon the earliest of the following:

(a)

immediately upon the termination of your Continuous Service for Cause;

(b)

three (3) months after the termination of your Continuous Service for any reason other than Cause, your Disability 
or your death (except as otherwise provided in Section 7(d) below); provided, however, that if during any part of such three (3) month period 
your option is not exercisable solely because of the condition set forth in the section above regarding “Securities Law Compliance,” your 
option will not expire until the earlier of the Expiration Date or until it has been exercisable for an aggregate period of three (3) months after 
the termination of your Continuous Service; provided further, if during any part of such three (3) month period, the sale of any Common 

3

 
Stock received upon exercise of your option would violate the Company’s insider trading policy, then your option will not expire until the 
earlier  of  the  Expiration  Date  or  until  it  has  been  exercisable  for  an  aggregate  period  of  three  (3)  months  after  the  termination  of  your 
Continuous  Service  during  which  the  sale  of  the  Common  Stock  received  upon  exercise  of  your  option  would  not  be  in  violation  of  the 
Company’s  insider  trading  policy.    Notwithstanding  the  foregoing,  if  (i)  you  are  a  Non-Exempt  Employee,  (ii)  your  Continuous  Service 
terminates within six (6) months after the Date of Grant, and (iii) you have vested in a portion of your option at the time of your termination 
of Continuous Service, your option will not expire until the earlier of (x) the later of (A) the date that is seven (7) months after the Date of 
Grant, and (B) the date that is three (3) months after the termination of your Continuous Service, and (y) the Expiration Date;

provided in Section 7(d)) below;

(c)

twelve (12) months after the termination of your Continuous Service due to your Disability (except as otherwise 

after your Continuous Service terminates for any reason other than Cause;

(d)

eighteen (18) months after your death if you die either during your Continuous Service or within three (3) months 

the Expiration Date indicated in your Grant Notice; or

the day before the tenth (10th) anniversary of the Date of Grant.

(e)

(f)

8. EXERCISE.

(a)

You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so 
permits) during its term by (i) delivering a Notice of Exercise (in a form designated by the Company) or completing such other documents 
and/or  procedures  designated  by  the  Company  for  exercise  and  (ii)  paying  the  exercise  price  and  any  applicable  withholding  taxes  to  the 
Company’s Secretary, stock plan administrator, or such other person as the Company may designate, together with such additional documents 
as the Company may then require.

(b)

By exercising your option you agree that, as a condition to any exercise of your option, the Company may require 
you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising 
by  reason  of  (i)  the  exercise  of  your  option,  (ii)  the  lapse  of  any  substantial  risk  of  forfeiture  to  which  the  shares  of  Common  Stock  are 
subject at the time of exercise, or (iii) the disposition of shares of Common Stock acquired upon such exercise.

9. TRANSFERABILITY.  Except as otherwise provided in this Section 9, your option is not transferable, except by will or by the laws 

of descent and distribution, and is exercisable during your life only by you.  

Certain  Trusts.    Upon  receiving  written  permission  from  the  Board  or  its  duly  authorized  designee,  you  may 
transfer your option to a trust if you are considered to be the sole beneficial owner (determined under Section 671 of the Code and applicable 
state law) while the option is held in the trust.  You and the trustee must enter into transfer and other agreements required by the Company.  

(a)

(b) Domestic Relations Orders.  Upon receiving written permission from the Board or its duly authorized designee, 
and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your 
option pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as 
permitted by Treasury Regulation 1.421-1(b)(2) that contains the information required by the Company to effectuate the transfer.  You are 
encouraged to discuss the proposed terms of any division of this option with the Company prior to finalizing the domestic relations order or 
marital settlement agreement to help ensure the required information is contained within the domestic relations order or marital settlement 
agreement.  

may, by delivering written notice to the Company, in a form approved by the Company and 

(c)

Beneficiary Designation.  Upon receiving written permission from the Board or its duly authorized designee, you 

4

 
any broker designated by the Company to handle option exercises, designate a third party who, on your death, will thereafter be entitled to 
exercise this option and receive the Common Stock or other consideration resulting from such exercise.  In the absence of such a designation, 
your executor or administrator of your estate will be entitled to exercise this option and receive, on behalf of your estate, the Common Stock 
or other consideration resulting from such exercise.

10.OPTION  NOT  A  SERVICE  CONTRACT.    Your  option  is  not  an  employment  or  service  contract,  and  nothing  in  your  option  will  be 
deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the 
Company or an Affiliate to continue your employment.  In addition, nothing in your option will obligate the Company or an Affiliate, their 
respective  stockholders,  boards  of  directors,  officers  or  employees  to  continue  any  relationship  that  you  might  have  as  a  Director  or 
Consultant for the Company or an Affiliate.

11.WITHHOLDING OBLIGATIONS.

(a)

At the time you exercise your option, in whole or in part, and at any time thereafter as requested by the Company, 
you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for 
(including by means of a “same day sale” pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board 
to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the 
Company or an Affiliate, if any, which arise in connection with the exercise of your option.  

(b) Upon your request and subject to approval by the Company, and compliance with any applicable legal conditions or 
restrictions,  the  Company  may  withhold  from  fully  vested  shares  of  Common  Stock  otherwise  issuable  to  you  upon  the  exercise  of  your 
option a number of whole shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in 
excess of the maximum amount of tax required to be withheld by law (or such lower amount as may be necessary to avoid classification of
your option as a liability for financial accounting purposes).    Notwithstanding the filing of such election, shares of Common Stock shall be 
withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to 
you upon such exercise.  Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole 
responsibility.

(c)

You may not exercise your option unless the tax withholding obligations of the Company and/or any Affiliate are 
satisfied.  Accordingly, you may not be able to exercise your option when desired even though your option is vested, and the Company will 
have  no  obligation  to  issue  a  certificate  for  such  shares  of  Common  Stock  or  release  such  shares  of  Common  Stock  from  any  escrow 
provided for herein, if applicable, unless such obligations are satisfied.

12.TAX  CONSEQUENCES.  You  hereby  agree  that  the  Company  does  not  have  a  duty  to  design  or  administer  the  Plan  or  its  other 
compensation  programs  in  a  manner  that  minimizes  your  tax  liabilities.  You  will  not  make  any  claim  against  the  Company,  or  any  of  its 
Officers, Directors, Employees or Affiliates related to tax liabilities arising from your option or your other compensation. In particular, you 
acknowledge that this option is exempt from Section 409A of the Code only if the exercise price per share specified in the Grant Notice is at 
least equal to the “fair market value” per share of the Common Stock on the Date of Grant and there is no other impermissible deferral of 
compensation associated with the option. 

13.NOTICES.    Any  notices  provided  for  in  your  option  or  the  Plan  will  be  given  in  writing  (including  electronically)  and  will  be 
deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the 
United  States  mail,  postage  prepaid,  addressed  to  you  at  the  last  address  you  provided  to  the  Company.    The  Company  may,  in  its  sole 
discretion, decide to deliver any documents related to participation in the Plan and this option by electronic means or to request your consent 
to participate in the Plan by electronic means.  By accepting this option, you consent to receive such documents by electronic delivery and to 
participate in the Plan through an on-line or electronic system established and maintained by the Company or another third party designated 
by the Company.

14.GOVERNING PLAN DOCUMENT.  Your option is subject to all the provisions of the Plan, the provisions of which are hereby made a 
part  of  your  option,  and  is  further  subject  to  all  interpretations,  amendments,  rules  and  regulations,  which  may  from  time  to  time  be 
promulgated  and  adopted  pursuant  to  the  Plan.    If  there  is  any  conflict  between  the  provisions  of  your  option  and  those  of  the  Plan,  the 
provisions of the Plan will control.  In addition, your option (and any compensation paid or shares issued under your option) is subject to 
recoupment  in  accordance  with  The  Dodd–Frank  Wall  Street  Reform  and  Consumer  Protection  Act  and  any  implementing  regulations 
thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable law.

15.OTHER DOCUMENTS.  You hereby acknowledge receipt of and the right to receive a document providing the information required 
by Rule 428(b)(1) promulgated under the Securities Act, which includes the Plan prospectus.  In addition, you acknowledge receipt of the 
Company’s  policy  permitting  certain  individuals  to  sell  shares  only  during  certain  “window”  periods  and  the  Company’s  insider  trading 
policy, in effect from time to time.

16.EFFECT ON OTHER EMPLOYEE BENEFIT PLANS.  The value of this option will not be included as compensation, earnings, salaries, 
or  other  similar  terms  used  when  calculating  your  benefits  under  any  employee  benefit  plan  sponsored  by  the  Company  or  any  Affiliate, 
except  as  such  plan  otherwise  expressly  provides.  The  Company  expressly  reserves  its  rights  to  amend,  modify,  or  terminate  any  of  the 
Company’s or any Affiliate’s employee benefit plans.

17.VOTING RIGHTS.  You will not have voting or any other rights as a stockholder of the Company with respect to the shares to be 
issued  pursuant  to  this  option  until  such  shares  are  issued  to  you.      Upon  such  issuance,  you  will  obtain  full  voting  and  other  rights  as  a 
stockholder of the Company.  Nothing contained in this option, and no action taken pursuant to its provisions, will create or be construed to 
create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

18.SEVERABILITY.  If all or any part of this Option Agreement or the Plan is declared by any court or governmental authority to be 
unlawful or invalid, such unlawfulness or invalidity will not invalidate any portion of this Option Agreement or the Plan not declared to be 
unlawful or invalid.  Any Section of this Option Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, 
be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining 
lawful and valid.

19.MISCELLANEOUS.

The rights and obligations of the Company under your option will be transferable to any one or more persons or 
entities,  and  all  covenants  and  agreements  hereunder  will  inure  to  the  benefit  of,  and  be  enforceable  by  the  Company’s  successors  and 
assigns. 

(a)

determination of the Company to carry out the purposes or intent of your option.

(b) You  agree  upon  request  to  execute  any  further  documents  or  instruments  necessary  or  desirable  in  the  sole 

the advice of counsel prior to executing and accepting your option, and fully understand all provisions of your option.

(c)

You acknowledge and agree that you have reviewed your option in its entirety, have had an opportunity to obtain 

governmental agencies or national securities exchanges as may be required.

(d)

This Option Agreement will be subject to all applicable laws, rules, and regulations, and to such approvals by any 

All obligations of the Company under the Plan and this Option Agreement will be binding on any successor to the 
Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or 
substantially all of the business and/or assets of the Company.

PERSONALIS, INC.

SECOND AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

This  Second  Amended  and  Restated  Executive  Severance  Agreement  (the  “Agreement”)  effective  as  of  September  25,  2023, 
amends, supersedes and restates in its entirety that certain First Amended and Restated Executive Severance Agreement by and between 
Christopher  Hall  (“Executive”)  and  Personalis,  Inc.  (the  “Company”)  dated  March  7,  2023.  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  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”):

(i)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.

(ii)The  Company  shall  pay  Executive  further  cash  severance  in  an  amount  equal  to  one  hundred  percent 
(100%) of Executive’s target annual bonus for the year in which the Change in Control is consummated, less all applicable withholdings 
and deductions, paid on the Company’s first regular payroll date following the Release Date.  

(iii)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.

(iv)The  Company  shall  accelerate  the  vesting  of  each  of  Executive’s  then-outstanding  unvested  equity 
compensation  awards,  effective  immediately  prior  to  such  Separation  from  Service.    In  the  event  any  such  awards  are  based  upon 
performance of the Company and/or of Executive, such awards shall be vested at their respective target levels.

(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”):

(i)The Company shall pay Executive cash severance in an amount equal to twelve (12) 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.

(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 twelve (12) 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 

2

 
 
 
 
 
 
 
 
 
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 
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 

3

 
 
 
 
 
 
 
 
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.

(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.

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 Company.

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  consummation  of  a 

immediately following which the stockholders of the Company 

(i)a merger, consolidation or similar corporate transaction involving (directly or indirectly) the Company and, 

4

 
 
 
 
 
 
 
 
 
 
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

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 Company that occurs 

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  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 

5

 
 
 
 
 
 
 
 
 
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.

(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 

6

 
 
 
 
 
 
 
 
 
 
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.

(c)This arbitration agreement shall not apply to any action or claim that cannot be subject to mandatory arbitration as a matter of 
law, 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.

(a) 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.

(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 

7

 
 
 
 
 
 
 
 
 
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.

(d) 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.

(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.

connection with the execution of this Agreement.

(f) Legal Fees and Expenses. The parties shall each bear their own expenses, legal fees and other fees incurred in 

(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.

all of which together will constitute one and the same instrument.

(h) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but

THIRD AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

PERSONALIS, INC. 

This  Third  Amended  and  Restated  Executive  Severance  Agreement  (the  “Agreement”),  effective  as  of  September  25, 
2023, amends, supersedes and restates in its entirety that certain Second Amended and Restated Executive Severance Agreement 
by and between Aaron Tachibana (“Executive”) and Personalis, Inc. (the “Company”) dated March 7, 2023.  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  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 

1

 
 
 
 
 
 
 
 
 
 
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”):

(i) 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.  

(ii) The  Company  shall  pay  Executive  further  cash  severance  in  an  amount  equal  to  one  hundred 
percent  (100%)  of  Executive’s  target  annual  bonus  for  the  year  in  which  the  Change  in  Control  is  consummated,  less  all 
applicable withholdings and deduction, paid on the Company’s first regular payroll date following the Release Date.  

(iii)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. 

(iv)The Company shall accelerate the vesting of each of Executive’s then-outstanding unvested equity 
compensation awards, effective immediately prior to such Separation from Service.  In the event any such awards are based upon 
performance of the Company and/or of Executive, such awards shall be vested at their respective target levels.  

(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 

2

 
 
Executive with the following severance benefits (collectively with the Change in Control Separation Benefits, the “Separation 
Benefits”):

(i) The  Company  shall  pay  Executive  cash  severance  in  an  amount  equal  to  nine  (9)  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.

(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  nine  (9)  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 

3

 
 
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  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 

4

 
 
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 Chief Executive Officer.

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 Company.

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 consummation of 

(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

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 Company that 

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 

5

 
 
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  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 

6

 
 
“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. 

(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

 
 
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.  

(c) This arbitration agreement shall not apply to any action or claim that cannot be subject to mandatory arbitration as a 
matter of law, 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

 
 
8. Miscellaneous Provisions.

(a) 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.

(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.

(d) 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.

(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.

incurred in connection with the execution of this Agreement.

(f)

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

(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.

THIRD AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

PERSONALIS, INC. 

Exhibit 10.14

This  Third  Amended  and  Restated  Executive  Severance  Agreement  (the  “Agreement”),  effective  as  of  September  25, 
2023, amends, supersedes and restates in its entirety that certain Second Amended and Restated Executive Severance Agreement 
by and between Dr. Richard Chen (“Executive”) and Personalis, Inc. (the “Company”) dated March 7, 2023.  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  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 

1

 
 
 
 
 
 
 
 
 
 
 
 
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”):

(i) 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.  

(ii) The  Company  shall  pay  Executive  further  cash  severance  in  an  amount  equal  to  one  hundred 
percent  (100%)  of  Executive’s  target  annual  bonus  for  the  year  in  which  the  Change  in  Control  is  consummated,  less  all 
applicable withholdings and deductions, paid on the Company’s first regular payroll date following the Release Date.  

(iii)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. 

(iv)The Company shall accelerate the vesting of each of Executive’s then-outstanding unvested equity 
compensation awards, effective immediately prior to such Separation from Service.  In the event any such awards are based upon 
performance of the Company and/or of Executive, such awards shall be vested at their respective target levels.  

(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 

2

 
 
Executive with the following severance benefits (collectively with the Change in Control Separation Benefits, the “Separation 
Benefits”):

(i) The  Company  shall  pay  Executive  cash  severance  in  an  amount  equal  to  nine  (9)  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.

(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  nine  (9)  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 

3

 
 
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  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 

4

 
 
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 Chief Executive Officer.

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 Company.

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 consummation of 

(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

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 Company that 

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 

5

 
 
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  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 

6

 
 
“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. 

(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

 
 
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.  

(c) This arbitration agreement shall not apply to any action or claim that cannot be subject to mandatory arbitration as a 
matter of law, 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

 
 
8. Miscellaneous Provisions.

(a) 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.

(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.

(d) 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.

(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.

incurred in connection with the execution of this Agreement.

(f)

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

(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.

SECOND AMENDED AND RESTATED EXECUTIVE SEVERANCE AGREEMENT

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

This Second Amended and Restated Executive Severance Agreement (the “Agreement”), effective as of September 18, 
2023, amends, supersedes and restates in its entirety that certain First Amended and Restated Executive Severance Agreement by 
and  between  Stephen  Moore  (“Executive”)  and  Personalis,  Inc.  (the  “Company”)  dated  March  18,  2022.    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  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) 

1

 
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”):

(i) 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.  

(ii) The  Company  shall  pay  Executive  further  cash  severance  in  an  amount  equal  to  seventy-five 
percent (75%) of Executive’s target annual bonus for the year in which the Change in Control is consummated, less all applicable 
withholdings and deductions, paid on the Company’s first regular payroll date following the Release Date.

(iii)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. 

(iv)The Company shall accelerate the vesting of each of Executive’s then-outstanding unvested equity 
compensation awards, effective immediately prior to such Separation from Service.  In the event any such awards are based upon 
performance of the Company and/or of Executive, such awards shall be vested at their respective target levels.

(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 

2

 
 
Executive with the following severance benefits (collectively with the Change in Control Separation Benefits, the “Separation 
Benefits”):

(i) 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.

(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 

3

 
 
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  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 

4

 
 
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 Chief Executive Officer.

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 Company.

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 consummation of 

(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

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 Company that 

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 

5

 
 
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  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 

6

 
 
“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. 

(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.  

7

 
 
(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.  

(c)

This  arbitration  agreement  shall  not  apply  to  any  action  or  claim  that  cannot  be  subject  to  mandatory 
arbitration  as  a  matter  of  law,  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.

8

 
 
(a) 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.

(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.

(d) 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.

(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.

incurred in connection with the execution of this Agreement.

(f)

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

(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.

INCENTIVE COMPENSATION RECOUPMENT POLICY

Adopted By the Compensation Committee of the Board of Directors: November 1, 2023

Exhibit 97

1.

INTRODUCTION

The  Compensation  Committee  (the  “Compensation Committee”)  of  the  Board  of  Directors  (the  “Board”)  of  PERSONALIS,  INC.,  a 
Delaware  corporation  (the  “Company”),  has  determined  that  it  is  in  the  best  interests  of  the  Company  and  its  stockholders  to  adopt  this 
Incentive  Compensation  Recoupment  Policy  (this  “Policy”)  providing  for  the  Company’s  recoupment  of  Recoverable  Incentive 
Compensation that is received by Covered Officers of the Company under certain circumstances. Certain capitalized terms used in this Policy 
have the meanings given to such terms in Section 3 below.

This Policy is designed to comply with, and shall be interpreted to be consistent with, Section 10D of the Exchange Act, Rule 10D-

1 promulgated thereunder (“Rule 10D-1”) and Nasdaq Listing Rule 5608 (the “Listing Standards”).

2.

EFFECTIVE DATE

This  Policy  shall  apply  to  all  Incentive  Compensation  that  is  received  by  a  Covered  Officer  on  or  after  October  2,  2023  (the 
“Effective Date”). Incentive Compensation is deemed “received” in the Company’s fiscal period in which the Financial Reporting Measure 
specified in the Incentive Compensation award is attained, even if the payment or grant of such Incentive Compensation occurs after the end 
of that period.

3.

DEFINITIONS

“Accounting  Restatement”  means  an  accounting  restatement  that  the  Company  is  required  to  prepare  due  to  the  material 
noncompliance  of  the  Company  with  any  financial  reporting  requirement  under  the  securities  laws,  including  any  required  accounting 
restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that 
would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

“Accounting Restatement Date” means the earlier to occur of (a) the date that the Board, a committee of the Board authorized to 
take  such  action,  or  the  officer  or  officers  of  the  Company  authorized  to  take  such  action  if  Board  action  is  not  required,  concludes,  or 
reasonably should have concluded, that the Company is required to prepare an Accounting Restatement, or (b) the date that a court, regulator 
or other legally authorized body directs the Company to prepare an Accounting Restatement.

“Administrator” means the Compensation Committee or, in the absence of such committee, the Board.

“Code” means the U.S. Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder.

“Covered Officer” means each current and former Executive Officer.

 
 
“Exchange” means the Nasdaq Stock Market.

“Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended.

“Executive Officer” means the Company’s president, principal financial officer, principal accounting officer (or if there is no such 
accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as 
sales, administration, or finance), any other officer who performs a policy-making function, or any other person who performs similar policy-
making  functions  for  the  Company.  Executive  officers  of  the  Company’s  parent(s)  or  subsidiaries  are  deemed  executive  officers  of  the 
Company if they perform such policy-making functions for the Company. Policy-making function is not intended to include policy-making 
functions  that  are  not  significant.  Identification  of  an  executive  officer  for  purposes  of  this  Policy  would  include  at  a  minimum  executive 
officers identified pursuant to Item 401(b) of Regulation S-K promulgated under the Exchange Act.

“Financial Reporting Measures” means measures that are determined and presented in accordance with the accounting principles 
used in preparing the Company’s financial statements, and any measures derived wholly or in part from such measures, including Company 
stock price and total stockholder return (“TSR”). A measure need not be presented in the Company’s financial statements or included in a 
filing with the SEC in order to be a Financial Reporting Measure.

“Incentive Compensation” means any compensation that is granted, earned or vested based wholly or in part upon the attainment of 

a Financial Reporting Measure. 

“Lookback Period” means the three completed fiscal years immediately preceding the Accounting Restatement Date, as well as any 
transition period (resulting from a change in the Company’s fiscal year) within or immediately following those three completed fiscal years 
(except that a transition period of at least nine months shall count as a completed fiscal year). Notwithstanding the foregoing, the Lookback 
Period shall not include fiscal years completed prior to the Effective Date. 

“Recoverable Incentive Compensation” means Incentive Compensation received by a Covered Officer during the Lookback Period 
that  exceeds  the  amount  of  Incentive  Compensation  that  would  have  been  received  had  such  amount  been  determined  based  on  the 
Accounting  Restatement,  computed  without  regard  to  any  taxes  paid  (i.e.,  on  a  gross  basis  without  regard  to  tax  withholdings  and  other 
deductions). For any compensation plans or programs that take into account Incentive Compensation, the amount of Recoverable Incentive 
Compensation  for  purposes  of  this  Policy  shall  include,  without  limitation,  the  amount  contributed  to  any  notional  account  based  on 
Recoverable  Incentive  Compensation  and  any  earnings  to  date  on  that  notional  amount.  For  any  Incentive  Compensation  that  is  based  on 
stock price or TSR, where the Recoverable Incentive Compensation is not subject to mathematical recalculation directly from the information 
in an Accounting Restatement, the Administrator will determine the amount of Recoverable Incentive Compensation based on a reasonable 
estimate of the effect of the Accounting Restatement on the stock price or TSR upon which the Incentive Compensation was received. The 
Company shall maintain documentation of the determination of that reasonable estimate and provide such documentation to the Exchange in 
accordance with the Listing Standards.

“SEC” means the U.S. Securities and Exchange Commission.

4.

RECOUPMENT

(a) Applicability  of  Policy.  This  Policy  applies  to  Incentive  Compensation  received  by  a  Covered  Officer  (i)  after  beginning 
services  as  an  Executive  Officer,  (ii)  who  served  as  an  Executive  Officer  at  any  time  during  the  performance  period  for  such  Incentive 
Compensation, (iii) while the Company had 

2

 
 
a class of securities listed on a national securities exchange or a national securities association, and (iv) during the Lookback Period. 

(b) Recoupment Generally.  Pursuant to the provisions of this Policy, if there is an Accounting Restatement, the Company must 
reasonably promptly recoup the full amount of the Recoverable Incentive Compensation, unless the conditions of one or more subsections of 
Section 4(c) of this Policy are met and the Compensation Committee, or, if such committee does not consist solely of independent directors, a 
majority of the independent directors serving on the Board, has made a determination that recoupment would be impracticable. Recoupment 
is required regardless of whether the Covered Officer engaged in any misconduct and regardless of fault, and the Company’s obligation to 
recoup Recoverable Incentive Compensation is not dependent on whether or when any restated financial statements are filed.  

(c) Impracticability of Recovery. Recoupment may be determined to be impracticable if, and only if:

(i)

the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount of the applicable 
Recoverable  Incentive  Compensation;  provided  that,  before  concluding  that  it  would  be  impracticable  to  recover  any  amount  of 
Recoverable Incentive Compensation based on expense of enforcement, the Company shall make a reasonable attempt to recover 
such Recoverable Incentive Compensation, document such reasonable attempt(s) to recover, and provide that documentation to the 
Exchange in accordance with the Listing Standards; or

(ii)

recoupment of the applicable Recoverable Incentive Compensation would likely cause an otherwise tax-qualified 
retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Code 
Section 401(a)(13) or Code Section 411(a) and regulations thereunder.

(d) Sources of Recoupment.  To the extent permitted by applicable law, the Administrator shall, in its sole discretion, determine the 
timing and method for recouping Recoverable Incentive Compensation hereunder, provided that such recoupment is undertaken reasonably 
promptly.  The  Administrator  may,  in  its  discretion,  seek  recoupment  from  a  Covered  Officer  from  any  of  the  following  sources  or  a 
combination thereof, whether the applicable compensation was approved, awarded, granted, payable or paid to the Covered Officer prior to, 
on  or  after  the  Effective  Date:  (i)  direct  repayment  of  Recoverable  Incentive  Compensation  previously  paid  to  the  Covered  Officer;  (ii) 
cancelling prior cash or equity-based awards (whether vested or unvested and whether paid or unpaid); (iii) cancelling or offsetting against 
any planned future cash or equity-based awards; (iv) forfeiture of deferred compensation, subject to compliance with Code Section 409A; 
and (v) any other method authorized by applicable law or contract. Subject to compliance with any applicable law, the Administrator may 
effectuate  recoupment  under  this  Policy  from  any  amount  otherwise  payable  to  the  Covered  Officer,  including  amounts  payable  to  such 
individual under any otherwise applicable Company plan or program, e.g., base salary, bonuses or commissions and compensation previously 
deferred by the Covered Officer. The Administrator need not utilize the same method of recovery for all Covered Officers or with respect to 
all types of Recoverable Incentive Compensation.

(e) No Indemnification of Covered Officers. Notwithstanding any indemnification agreement, applicable insurance policy or any 
other agreement or provision of the Company’s certificate of incorporation or bylaws to the contrary, no Covered Officer shall be entitled to 
indemnification  or  advancement  of  expenses  in  connection  with  any  enforcement  of  this  Policy  by  the  Company,  including  paying  or 
reimbursing such Covered Officer for insurance premiums to cover potential obligations to the Company under this Policy.

3

 
 
(f) Indemnification of Administrator. Any members of the Administrator, and any other members of the Board who assist in the 
administration of this Policy, shall not be personally liable for any action, determination or interpretation made with respect to this Policy and 
shall  be  indemnified  by  the  Company  to  the  fullest  extent  under  applicable  law  and  Company  policy  with  respect  to  any  such  action, 
determination or interpretation. The foregoing sentence shall not limit any other rights to indemnification of the members of the Board under 
applicable law or Company policy.

(g) No “Good Reason” for Covered Officers.  Any action by the Company to recoup or any recoupment of Recoverable Incentive 
Compensation under this Policy from a Covered Officer shall not be deemed (i) “good reason” for resignation or to serve as a basis for a 
claim of constructive termination under any benefits or compensation arrangement applicable to such Covered Officer, or (ii) to constitute a 
breach of a contract or other arrangement to which such Covered Officer is party.

5.

ADMINISTRATION

Except as specifically set forth herein, this Policy shall be administered by the Administrator. The Administrator shall have full and 
final authority to make any and all determinations required under this Policy.  Any determination by the Administrator with respect to this 
Policy shall be final, conclusive and binding on all interested parties and need not be uniform with respect to each individual covered by this 
Policy. In carrying out the administration of this Policy, the Administrator is authorized and directed to consult with the full Board or such 
other committees of the Board as may be necessary or appropriate as to matters within the scope of such other committee’s responsibility and 
authority. Subject to applicable law, the Administrator may authorize and empower any officer or employee of the Company to take any and 
all  actions  that  the  Administrator,  in  its  sole  discretion,  deems  necessary  or  appropriate  to  carry  out  the  purpose  and  intent  of  this  Policy 
(other than with respect to any recovery under this Policy involving such officer or employee).

6.

SEVERABILITY

If  any  provision  of  this  Policy  or  the  application  of  any  such  provision  to  a  Covered  Officer  shall  be  adjudicated  to  be  invalid, 
illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Policy, and 
the invalid, illegal or unenforceable provisions shall be deemed amended to the minimum extent necessary to render any such provision or 
application enforceable.

7.

NO IMPAIRMENT OF OTHER REMEDIES

Nothing contained in this Policy, and no recoupment or recovery as contemplated herein, shall limit any claims, damages or other 
legal  remedies  the  Company  or  any  of  its  affiliates  may  have  against  a  Covered  Officer  arising  out  of  or  resulting  from  any  actions  or 
omissions by the Covered Officer. This Policy does not preclude the Company from taking any other action to enforce a Covered Officer’s 
obligations to the Company, including, without limitation, termination of employment and/or institution of civil proceedings. This Policy is in 
addition  to  the  requirements  of  Section  304  of  the  Sarbanes-Oxley  Act  of  2002  (“SOX 304”)  that  are  applicable  to  the  Company’s  Chief 
Executive  Officer  and  Chief  Financial  Officer  and  to  any  other  compensation  recoupment  policy  and/or  similar  provisions  in  any 
employment, equity plan, equity award, or other individual agreement, to which the Company is a party or which the Company has adopted 
or may adopt and maintain from time to time; provided, however, that compensation recouped pursuant to this Policy shall not be duplicative 
of  compensation  recouped  pursuant  to  SOX  304  or  any  such  compensation  recoupment  policy  and/or  similar  provisions  in  any  such 
employment, equity plan, equity award, or other individual agreement except as may be required by law.

4

 
 
8.

AMENDMENT; TERMINATION

The Administrator may amend, terminate or replace this Policy or any portion of this Policy at any time and from time to time in its 

sole discretion. The Administrator shall amend this Policy as it deems necessary to comply with applicable law or any Listing Standard.

9.

SUCCESSORS

This  Policy  shall  be  binding  and  enforceable  against  all  Covered  Officers  and,  to  the  extent  required  by  Rule  10D-1  and/or  the 

applicable Listing Standards, their beneficiaries, heirs, executors, administrators or other legal representatives.

10.  REQUIRED FILINGS

The Company shall make any disclosures and filings with respect to this Policy that are required by law, including as required by the 

SEC.
