BUSINESS 

Note: A glossary of terms used in this Form 10-K appears at the end of this Item 1. 

PART I 

Overview  

We are a diagnostics company with proprietary molecular and bioinformatics technology that we are applying to 
change the management of disease worldwide. Our cell-free DNA, or cfDNA, technology combines our novel molecular 
assays, which reliably measure many informative regions across the genome from samples as small as a single cell, with 
our  statistical  algorithms  which  incorporate  data  available  from  the  broader  scientific  community  to  identify  genetic 
variations covering a wide range of serious conditions with best-in-class accuracy and coverage. Our technology has been 
proven  clinically  and  commercially  in  the  women’s  health  space,  in  which  we  develop  and  commercialize  non-  or 
minimally- invasive tests to evaluate risk for, and thereby enable early detection of, a wide range of genetic conditions, 
such as Down syndrome. We are now translating our success in women’s health and applying our core technology to the 
oncology market, in which we are commercializing a personalized blood-based DNA test to detect molecular residual 
disease  and  monitor  disease  recurrence,  as  well  as  to  the  organ  health  market,  initially  with  a  test  to  assess  kidney 
transplants  for  rejection.  We  seek  to  enable  even  wider  adoption  of  our  technology  through  our  global  cloud-based 
distribution  model.  In  addition  to  our  direct  sales  force  in  the  United  States,  we  have  a  global  network  of  over  100 
laboratory and distribution partners, including many of the largest international laboratories.  

Since 2009, we have launched a comprehensive suite of 11 products in the women’s health space, as well as 

products in oncology and in organ health. We intend to continue to launch new products in the future. 

We launched Panorama, our non-invasive prenatal test, or NIPT, in 2013 and have since gone from being the 
fourth company to enter the NIPT market to being the market leader by volume in the United States. We launched our 
Horizon carrier screening test in 2012. Panorama and Horizon together represent the significant majority of our revenues. 
Our revenues were $391.0 million in 2020 compared to $302.3 million in 2019 and $257.7 million in 2018. Our product 
revenues, which are primarily generated from testing in women’s health, were $367.2 million, $269.9 million and $240.4 
million for the years ended December 31, 2020, 2019 and 2018, respectively. Our net losses increased to $229.7 million 
in 2020 from $124.8 million in 2019 and $128.2 million in 2018.  

Our Solution  

In women’s health, oncology and organ health, the use of blood-based tests offers significant advantages over 
older methods, but the significant technological challenge is that such testing often requires the measurement of very small 
amounts of relevant genetic material – fetal DNA in reproductive health, tumor DNA in oncology, and donor DNA in 
transplant rejection – circulating within a much larger blood sample. Our approach combines proprietary molecular biology 
and computational techniques to measure genomic variations in tiny amounts of DNA, as small as a single cell.  

DNA  is  a  naturally  occurring  information  storage  system  that  conveys  genetic  inheritance.  DNA  stores 
information in a linear sequence of the chemical bases adenine, cytosine, guanine and thymine, represented by the symbols 
A, C, G, and T. Billions of bases of A, C, G, and T link together inside living cells to form the genome, which can be read 
like a code or a molecular blueprint for life. While differences in the specific sequence and structure of this code drive 
biological diversity, certain variations can also cause disease. Examples of genetic diversity include CNVs and SNVs. A 
CNV is a genetic mutation in which relatively large regions of the genome have been deleted or duplicated, and an SNV 
is a mutation where a single base has changed. When single base changes are common in the population, that position on 
the chromosome, or loci, is called a single nucleotide polymorphism, or SNP. 

6 

 
 
 
Our molecular biology techniques are based on measuring thousands of SNPs simultaneously using massively 
multiplexed polymerase chain reaction, or mmPCR, to multiplex, or target, many thousands of regions of the genome 
simultaneously in a single test reaction. Our method avoids losing molecules, which can happen when samples are split 
into separate reaction tubes, so that all relevant variants can be detected. To make sense of the resulting deep and rich set 
of biological data and deliver a test result, we have developed computationally intensive algorithms that combine the data 
generated by mmPCR with the ever-expanding set of publicly available data on genetic variations. Our technologies allow 
us to achieve a high signal-to-noise ratio when detecting fragments of DNA at frequencies as low as a single copy, which 
allows us to deliver tests with a high degree of specificity and sensitivity. Furthermore, our women’s health tests assess 
the risk of a broad range of conditions, which we refer to as “clinical coverage,” including common fetal aneuploidies, 
microdeletions, triploidy, and inherited genetic conditions that could be passed on from parent to child, from a single blood 
draw. 

We  believe  our  approach  represents  a  fundamental  advance  in  molecular  biology.  In  women’s  health,  this 
approach is distinct from the approach employed with other commercially available NIPTs, which use first-generation 
“quantitative”, or counting, methods to compare the relative number of sequence reads from a chromosome of interest to 
a  reference  chromosome.  Based  on  data  published  in  the  journals  Obstetrics  &  Gynecology,  American  Journal  of 
Obstetrics & Gynecology, Prenatal Diagnosis, and others, we believe Panorama is the most accurate NIPT commercially 
available in the United States. In oncology, where we have demonstrated the ability to detect circulating tumor DNA, or 
ctDNA, with a high degree of sensitivity and specificity, we believe our Signatera assay is the only ctDNA test that is 
custom designed for, informed by and specific to, the tumor DNA for each patient. In organ health, we have demonstrated 
the ability of our technology to measure the fraction of cell-free DNA that is donor-derived, or dd-cfDNA, which is DNA 
that is shed from a transplanted organ into circulation. Published studies of the performance of our Prospera transplant 
rejection test in both clinical and analytical validation report higher sensitivity and higher area under the curve, or AUC, 
than both the current standard of care and the competing test. The current standard of care in transplant rejection detection 
uses  functional  impairment  assessed  by  serum  creatinine  or  estimated  glomerular  filtration  rate,  or  eGFR,  which  are 
clinically accepted but potentially inaccurate approaches for assessing active transplant rejection.  

Our technology is compatible with standard equipment used globally and a range of next generation sequencing, 
or NGS, platforms, and we have optimized our algorithms to enable laboratories around the world to run tests locally and 
access  our  algorithms  in  the  cloud  using  our  Constellation  platform.  We  sell  our  tests  directly  and  partner  with  other 
clinical  laboratories  to  distribute  our  tests  globally.  Currently,  all  of  our  products  other  than  our  Constellation  cloud 
software  product  are  laboratory  developed  tests,  or  LDTs.  We  perform  commercial  testing  in  our  CLIA-certified 
laboratories. 

Our Technology 

An illustration of the resolution that can be achieved with our mmPCR capability is provided below. The figures 
display data from our approximately 20,000 primer mmPCR assay, where each primer targets one SNP. On the left, the 
assay is applied to a large genomic DNA sample from a child. On the right, the assay is applied to a single cell from the 
same child. Each dot represents data from a particular SNP location on a chromosome. The assay measures the amount of 
each of the two possible sequences of nucleotides, or alleles, at each SNP. The plots below show the relative proportion 
of the two alleles, plotted along the vertical axis, for each of the approximately 20,000 SNPs, arranged sequentially along 
the vertical axis. The two alleles are arbitrarily labeled A and B, and each dot is colored according to the allelic contribution 
of the mother—red (A) or blue (B). Those SNPs where both copies of DNA in the child contain only the A allele are red 
and are found at the very top of the plot, and those SNPs where both copies of DNA in the child contain only the B allele 
are blue and are found at the very bottom of the plot. The SNPs where the fetus contains at least one copy of the A allele 
and one copy of the B allele are found near the center of the plot. The four vertical bars separated by dotted lines display 
data from chromosomes 13 (Patau syndrome), 18 (Edwards syndrome), 21 (Down syndrome) and X. For chromosomes 
13, 18 and X, the middle band is centered on 0.5; which indicates that for those SNPs, the child has one copy of the A 
allele  and  one  copy  of  a  B  allele  (and  therefore  a  relative  proportion  of  0.5),  and,  therefore,  has  the  right  number  of 
chromosomes—two. In this sample, an additional chromosome is present at chromosome 21, which indicates the presence 
of trisomy 21. For chromosome 21, the bands centered at 0.33 and 0.66 signal the additional nucleotides contributed by 
the mother. The band centered at 0.33 represents SNPs where the child has two copies of the B allele and one copy of the 

7 

 
 
 A allele, and the band centered at 0.66 represents SNPs where the child has two copies of the A allele and one copy of the 
B allele. The assay clearly quantifies the difference between single molecules of a particular allele at each SNP. The images 
demonstrate our ability to derive actionable information from tiny quantities of DNA, as the data from a single cell in the 
image on the right is nearly as informative as the data from a large genomic sample in the image on the left. 

Our bioinformatics technology utilizes proprietary complex statistical techniques to combine the measurements 
of  our  molecular  assays  with  our  internal  databases  and  the  vast  and  growing  sources  of  publicly  available  genomic 
information to build highly detailed models of the genome of interest. As our patient volumes grow, our internal database 
of samples with genetic mutations and corresponding clinical outcomes further enhances our ability to interpret the clinical 
significance of complex genetic mutations. As the genomic data from the scientific community, such as from the Cosmic 
Database and the Cancer Genome Atlas, becomes richer, we can seamlessly integrate new clinical knowledge into our 
bioinformatics algorithm, driving further improvement in our tests.  

Women’s Health 

In women’s health, we provide testing to support a spectrum of women’s health needs, from family planning and 

prenatal testing to hereditary cancer screening.  

Panorama 

Panorama helps physicians assess the risk of fetal genetic abnormalities by non-invasively screening for fetal 
chromosomal  abnormalities,  including  Down  syndrome,  Edwards  syndrome,  Patau  syndrome,  Turner  syndrome  and 
triploidy,  which  often  result  in  intellectual  disability,  severe  organ  abnormalities  and  miscarriage.  Panorama  can  also 
identify  fetal  sex  for  single  birth  pregnancies  as  well  as  of  each  fetus  in  twin  pregnancies.  Panorama  is  also  the  only 
commercially  available  NIPT  that  can  determine  whether  a  set  of  twins  is  identical,  or  monozygotic,  or  fraternal,  or 
dizygotic. Identifying a monozygotic twin pregnancy can prompt earlier, targeted ultrasound assessments for chorionicity 
and  associated  complications,  while  knowing  that  a  twin  pregnancy  is  dizygotic  reduces  concerns  about  certain 
complications,  such  as  twin-twin  transfusion  syndrome.  Panorama  demonstrates  the  capabilities  of  our  technology  by 
employing our fundamentally unique approach of simultaneously measuring thousands of SNPs in a single test reaction to 
identify genetic variations in fetal DNA with a high degree of specificity and sensitivity, which we believe can give patients 
and  their  physicians  a  greater  degree  of  comfort  in  choosing  to  forego  unnecessary  invasive  procedures,  limiting  the 
resulting risk of spontaneous miscarriage associated with invasive procedures and lowering the total cost to the healthcare 
system of these procedures. Panorama screens for common genetic conditions that affect both high-risk pregnancies, where 
maternal age is over 35 and which we estimate represent 19% of the approximately 4.4 million pregnancies in the United 
States, or approximately 800,000 pregnancies, and average-risk pregnancies, which we estimate represent approximately 
3.6 million pregnancies in the United States. 

8 

 
 
 
   
 
  
 
Panorama is performed on a maternal blood sample and can be performed as early as nine weeks into a pregnancy, 
which is significantly earlier than traditional methods, such as serum protein measurement whereby doctors measure the 
presence and amount of certain hormones in the blood. Panorama starts with a simple blood draw from the mother, either 
in a doctor’s office, in a laboratory or through a phlebotomist that may travel to the patient, and the sample is sent to one 
of our CLIA-certified and CAP-accredited laboratories for processing. After Panorama generates its result, we provide the 
doctor or the laboratory with a simple report showing the risk that abnormalities are present in the fetus.  

The  analytic  and  clinical  validity  of  our  technology  demonstrated  in  NIPT  has  been  described  in  more  peer-
reviewed publications covering more patients than our competitors. Based on data published in Prenatal Diagnosis, Fetal 
Diagnosis and Therapy and Obstetrics & Gynecology, Panorama demonstrated greater than 99% overall sensitivity for 
aneuploidies on  chromosomes 13, 18  and  21  and  triploidy  and  specificity of greater  than 99.9%  (less  than  0.1% false 
positive rate) for each disorder, which we believe makes it overall the most accurate NIPT commercially available in the 
United States. A paper published in Obstetrics & Gynecology reported that Panorama had a statistically significant lower 
false positive rate than other NIPT methods practiced by our U.S. competitors. Based on data published in Obstetrics & 
Gynecology,  Prenatal  Diagnosis,  and  American  Journal  of  Obstetrics  &  Gynecology,  we  have  also  demonstrated  the 
ability to identify fetal sex more accurately than competing NIPTs. This is partially a result of Panorama's unique ability 
to detect a vanishing twin, which is a known driver of fetal sex errors with quantitative methods used by our competitors. 
The American Journal of Obstetrics & Gynecology noted that the ability of Panorama to identify additional fetal haplotypes 
is expected to result in fewer false positive calls and prevent incorrect fetal sex calls. A study reporting on the use of 
Panorama in over 30,000 women, published in the American Journal of Obstetrics & Gynecology, supported the use of 
NIPT as a first-line screening test for aneuploidy. 

Our  Panorama  microdeletions  panel  screens  for  five  of  the  most  common  genetic  diseases  caused  by 
microdeletions  –  22q11.2  deletion  syndrome  (DiGeorge  syndrome),  1p36  deletion,  Angelman  syndrome,  Cri-du-chat 
syndrome and Prader-Willi syndrome. Microdeletions are missing sub-chromosomal pieces of DNA, and can have serious 
health  implications  depending  on  the  location  of  the  deletion.  Unlike  Down  syndrome,  where  the  risk  increases  with 
maternal age, the risk of these five microdeletions is independent of maternal age. Based on data published in Prenatal 
Diagnosis and American Journal of Obstetrics & Gynecology, the combined prevalence of these targeted microdeletions 
is approximately one in 1,000 pregnancies, which collectively makes them more common than Down syndrome for women 
younger than approximately 28 years of age. Furthermore, we estimate that triploidy and the aneuploidy and microdeletion 
conditions that we screen for combined are more than three times as prevalent in the general population as the three most 
common autosomal aneuploidies, trisomies 13, 18, and 21, alone. Diseases caused by microdeletions are often not detected 
via common screening techniques such as ultrasound or hormone-based screening, yet the presence of a microdeletion can 
critically  impact  postnatal  treatment.  For  example,  when  learning  prior  to  birth  that  a  newborn  has  22q11.2  deletion 
syndrome,  doctors  will know  to  monitor  the  infant  and  administer  calcium  if needed  to  avoid  seizures  and  permanent 
cognitive impairment, and will know to avoid administering routine vaccinations due to the immunodeficiency frequently 
associated with this condition. 

Panorama  has  demonstrated  best-in-class  performance  in  screening  for  microdeletions.  Panorama  achieved 
sensitivity of 90% for deletions of approximately 2.9Mb for 22q11.2 deletion syndrome, based on a validation study that 
contained 10 positives. It has also been validated to perform at low fetal fractions, which refers to the percentage of fetal 
DNA in a maternal plasma sample. Based on data published in the February 2018 issue of Clinical Genetics, Panorama 
demonstrated a PPV of 44.2% and false positive rate of 0.07% for 22q11.2 deletion syndrome. Furthermore, in 2021 we 
expect to publish the results of our SNP-based Microdeletions and Aneuploidy RegisTry (SMART) observational study 
to evaluate the performance of SNP-based NIPT for 22q11.2 deletion syndrome by tracking birth outcomes in the general 
population  among  over  18,000  women  who  presented  clinically  and  elected  Panorama  microdeletion  and  aneuploidy 
screening  as  part  of  their  routine  care.  In  conducting  this  study,  we  reviewed  perinatal  medical  records  and  collected 
postnatal DNA in order to perform genetic diagnostic testing for 22q11.2 deletion syndrome, comparing results from the 
follow-up specimens to those obtained by the Panorama screening test to determine test performance, particularly PPV. 

Panorama is also the only commercially available NIPT for twin pregnancies that can distinguish between each 
twin’s DNA, and therefore can determine zygosity, or whether the twins are identical or fraternal, and the fetal sex of each 
twin. Determining zygosity early in a pregnancy can help guide the management of a pregnancy, as certain monozygotic, 

9 

 or identical twin, pregnancies are at higher risk for various complications such as twin-twin transfusion syndrome, where 
there is an unequal sharing of blood, and therefore unequal growth, between the twins. Panorama screens twin pregnancies 
for  Down,  Edwards  and  Patau  syndromes  and,  for  identical  twins,  Turner  syndrome  and  22q11.2  deletion  syndrome, 
among others. In validation studies, Panorama identified identical twins with >99% sensitivity and specificity and achieved 
a combined sensitivity of >99% and specificity of >99% for Down, Edwards and Patau syndromes in twin pregnancies. 

Panorama's commercial performance has been consistent with our initial validation data. Data published in the 
Journal of Clinical Medicine on over one million commercial cases of Panorama that were screened for Down, Edwards, 
Patau and Turner syndromes demonstrated an overall PPV of 90% for all indications combined. We believe Panorama's 
performance  in  commercial  practice  represents  a  significant  improvement  over  first-generation  NIPTs  that  rely  on 
quantitative methods. Because Panorama does not require a reference chromosome, it is uniquely able to detect triploidy 
as  well  as  full  molar  pregnancies.  Panorama’s  ability  to  differentiate  between  maternal  and  fetal  DNA  also  allows 
Panorama  to  identify  the  presence  of  a  vanishing  twin,  as  well  as  maternal  abnormalities,  which  have  been  shown  in 
multiple studies to lead to false positives when using quantitative methods, particularly in the sex chromosomes where 
maternal abnormalities are common. 

Panorama has demonstrated substantial commercial success to date. We believe our test performance – including 
our continuous research, development and innovation to improve performance and efficiency – has allowed us to command 
a price premium compared to low-cost NIPTs while continuing to maintain growth in volume and revenue from Panorama. 

Horizon 

Horizon helps couples determine if they are carriers of genetic mutations that cause specific diseases. Depending 
on the disease, if one or both parents are carriers for a specific disease, it could result in a child affected with the disease. 
Many people do not know they are a carrier for an inherited genetic disease until they have an affected child. These diseases 
are rare and usually there is no family history, and although certain disorders are more common in certain ethnic groups, 
ethnicity may not be a reliable predictor of carrier status, as patients are increasingly of mixed or uncertain ethnicities. The 
industry’s approach to carrier screening has accordingly evolved over time, from ethnic-based screening targeting specific 
ethnicities with a higher incidence of screened conditions, to pan-ethnic screening for certain recommended conditions 
available to all patients, and most recently to expanded screening for many conditions simultaneously.  

Horizon was created based on recommended screening guidelines from ACOG, ACMG, and the Victor Center 
for the Prevention of Jewish Genetic Diseases. Horizon screens for up to 274 inherited diseases, including Cystic Fibrosis, 
Duchenne Muscular Dystrophy, or DMD, Spinal Muscular Atrophy, Fragile X Syndrome and other conditions. The blood 
or saliva sample required for Horizon can be obtained simultaneously with the blood sample required for Panorama, which 
makes it easier for us to offer, and for patients to take, both tests. Horizon employs various methodologies, including next 
generation sequencing and copy number analysis, often in combination in order to increase test sensitivity, to analyze the 
DNA from the individual’s blood or saliva sample to determine if the individual is a carrier for the genetic diseases being 
screened. 

Other reproductive health products 

While  Panorama  and  Horizon  represent  the  significant  majority  of  our  women’s  health  revenues,  we  offer  a 
portfolio of tests in reproductive and women’s health. Our Vistara NIPT screens for 25 single-gene disorders that cause 
severe  skeletal,  cardiac  and  neurological  conditions  which  affect  quality  of  life,  are  often  associated  with  cognitive 
disabilities  and  may  benefit  from  medical  and/or  surgical  intervention.  The  conditions  screened  by  Vistara  have  a 
combined incidence of approximately 1 in 600, which is higher than that of Down syndrome as well as Cystic Fibrosis, 
but may otherwise go undetected until after birth or into childhood as traditional NIPTs do not screen for these conditions, 
prenatal  ultrasound  findings  are  not  a  reliable  indicator,  and  family  history  is  not  a  good  indicator  of  risk  for  these 
conditions, which are commonly caused by new, and not inherited, mutations. Screening for these conditions early in a 
pregnancy  can  facilitate  early  diagnosis,  enable  patients  to  be  referred  to  MFMs  and  other  specialists  for  targeted 
evaluations,  to  guide  labor  and  delivery  management,  and  to  allow  families  to  mobilize  resources,  ask  questions  and 

10 

anticipate future needs. We have received a CE Mark for Vistara from the European Commission. In validation studies, 
Vistara demonstrated a combined analytical sensitivity and analytical specificity of greater than 99%. 

Spectrum comprises our preimplantation genetic tests for couples undergoing IVF. Spectrum can improve the 
chance  of  a  successful  pregnancy  while  reducing  the  chance  of  miscarriage  or  of  having  a  child  with  a  chromosome 
condition, by helping to identify the healthiest embryos during an IVF cycle. Spectrum PGT-A evaluates the number of 
chromosomes in embryos to detect extra or missing pieces of chromosomes prior to transfer of embryos created through 
IVF procedures, which have a high rate of non-viable chromosomal abnormalities, known as aneuploidy. Couples that are 
at risk of having a child with an inherited genetic disorder can also be tested for single gene conditions (PGT-M), which 
predicts  which  embryos  are  affected  with  specific  genetic  disorders;  and  PGT-SR  can  be  used  to  test  for  inherited 
translocations or inversions, or extra or missing chromosome pieces. This allows IVF physicians to select and transfer 
chromosomally normal embryos. In particular, aneuploidy is common in human embryos—particularly as women age—
and is the primary cause of failed IVF. PGT-A has been shown to improve IVF outcomes for all women, regardless of 
maternal age. In a study published in April 2018, a retrospective analysis of pregnancy outcomes demonstrated that use of 
Spectrum during IVF led to increased rates of implantation, including in older women, clinical pregnancy, and live births. 
The study findings also demonstrated that use of PGT-A can increase the use of single embryo transfer, which can reduce 
the  risks  of  multiple  pregnancies.  Spectrum  incorporates  our  proprietary  technology  to  further  screen  for  uniparental 
disomy, in which two copies of a chromosome come from the same parent, confirm parentage, and determine the parental 
origin of the chromosomal abnormality.  

Anora is our products of conception, or POC, test, which analyzes miscarriage tissue from women who have 
experienced one or more pregnancy losses to determine whether there was an underlying chromosomal reason for the loss. 
Anora can detect trisomy, triploidy, extra or missing chromosome pieces, and uniparental disomy. The Anora test is helpful 
to obstetricians, gynecologists and IVF physicians in supporting their patients’ reproductive goals. Anora can help couples 
understand the likelihood of another miscarriage, their future reproductive options, and whether there are any steps that 
may help them avoid a miscarriage in future pregnancies.  

Our non-invasive prenatal paternity product allows a couple to safely establish paternity without waiting for the 
child to be born. Testing can be done as early as nine weeks in gestation using a blood draw from the pregnant mother and 
alleged  father.  Our  internal  data  indicates  that  the  accuracy  of  this  test  is  greater  than  99.99%.  We  have  licensed  this 
technology to a third party to perform the test in its clinical laboratory.  

Oncology 

Signatera 

In oncology, we have been initially focused on detecting molecular residual disease, which we refer to as MRD, 
and recurrence monitoring in solid tumors, where we have generated data in over a dozen different cancer types and have 
published data in lung, bladder, colorectal and breast cancer. Molecular residual disease is the presence of small traces of 
cancer in the blood, such as ctDNA or microscopic pieces of tumor DNA that are often undetectable with standard imaging 
techniques.  If  left  untreated,  residual  cancer  cells  can  multiply  and  cause  recurrence.  MRD  testing  and  molecular 
monitoring offers the potential for physicians to change or escalate treatment in patients who are MRD-positive, and to 
de-escalate  or  avoid  unnecessary  treatment  in  patients  who  are  MRD-negative.  It  also  holds  potential  as  a  surrogate 
endpoint in clinical trials. Based on our internal estimates, we believe that the total addressable market in the United States 
for recurrence and treatment monitoring for solid tumor cancers is over $15 billion. 

Signatera is our personalized ctDNA blood test for MRD assessment and surveillance of disease recurrence in 
patients previously diagnosed with cancer. Each patient receives a custom assay that tracks the presence of 16 tumor-
specific clonal mutations that are selected based on the unique mutational signature found in that patient’s tumor tissue, 
which is intended to maximize accuracy for detecting the presence or absence of residual disease in a blood sample, even 
at variant allele frequency (VAF) of mutations as low as 0.01% in the blood. We believe this approach is optimal in the 
MRD setting, in which it is common for tumor DNA to be present only at low frequencies immediately after treatment. 
Unlike  static  liquid  biopsy  panels,  which  screen  for  a  generic  set  of  mutations  independent  of  an  individual’s  tumor, 

11 

Signatera is not intended to match patients with any particular therapy. Rather, it is intended to detect and quantify how 
much  cancer  is  left  in  the  body,  detect  recurrence  earlier,  and  help  optimize  treatment  decisions.  Signatera  can  detect 
residual disease earlier than clinical or radiological recurrence in patients with solid tumors who have received treatment.  

We launched Signatera in 2017 for research use only to cancer researchers and biopharmaceutical companies. 
Signatera was commercially launched in 2019 for clinical use as an LDT in our own CLIA-certified and CAP-accredited 
laboratory. We have received a final Medicare local coverage determination for the use of Signatera in patients with certain 
forms of colorectal cancer. CMS has also issued a draft local coverage determination proposing expanded coverage to 
include  immunotherapy  response  monitoring  as  well  as  creating  a  pathway  for  coverage  of  the  use  of  Signatera  in 
additional solid tumor types and indications, where it is clinically validated with peer-reviewed evidence and where the 
clinical utility is established. Signatera has been designated as a Breakthrough Device by the FDA for use in the post-
surgical  detection  and  quantification  of  ctDNA  in  patients  previously  diagnosed  with  certain  types  of  cancer  and  in 
combination with certain drugs. 

Signatera has been shown in various clinical studies to identify MRD significantly earlier than standard diagnostic 
tools, and that Signatera test status is a significant indicator of long-term patient outcomes after surgery and treatment, 
relative to other clinical and pathological factors. In a clinical validation study conducted in collaboration with Aarhus 
University in Denmark, published in JAMA Oncology, Signatera detected relapse in patients with Stage II-III colorectal 
cancer an average of 8.7 months earlier than standard diagnostic tools. Patients who remained MRD-negative throughout 
the study had significantly reduced risk of relapse, as low as 3%. This study, along with another research collaboration 
with Aarhus University in locally advanced muscle invasive bladder cancer, published in Journal of Clinical Oncology, 
demonstrated the ability of Signatera to stratify patients by whether they are MRD positive or negative based on post-
treatment presence or absence of ctDNA in the blood. In both the colorectal and bladder cancer studies, a positive Signatera 
test  result  after  treatment  was  the  strongest  prognostic  marker  of  disease  recurrence  and  long-term  patient  outcomes, 
relative to all other risk factors. 

We  have  also  published  results  in  lung  cancer.  Our  technology  was  selected  for  use  in  Cancer  Research 
UK/University College London’s Tracking Cancer Evolution through Therapy (TRACERx) clinical trial for the multi-
year monitoring of patient-specific SNVs in plasma, to understand the evolution of cancer mutations over time, and to 
monitor patients for disease recurrence. Results from the first 100 early-stage lung cancer patients analyzed as part of the 
study were featured on the cover of the May 2017 issue of Nature and showed that an early prototype version of Signatera 
identified 43% more ctDNA-positive early-stage lung cancer cases than a generic lung cancer panel and demonstrated its 
potential to detect residual disease, measure treatment response, and identify recurrence an average of four months earlier 
than the standard of care, with a sensitivity of 93% at time of relapse.  

We have also completed two studies in breast cancer. In our study with Cancer Research UK-funded researchers 
at Imperial College London and the University of Leicester, U.K. published in Clinical Cancer Research, which included 
patients with all three of the key breast cancer subtypes (ER+, HER2+, and Triple Negative), Signatera detected molecular 
residual disease with a lead time of up to two years prior to clinical or radiological detection, and overall detected clinical 
relapse with a sensitivity of 89% at time of relapse. Our second study in breast cancer, the Investigation of Serial Studies 
to  Predict  Your  Therapeutic  Response  with  Imaging  and  Molecular  Analysis  2  (I-SPY  2)  trial  with  the  University  of 
California,  San  Francisco  and  QuantumLeap  Healthcare  Collaborative,  launched  in  2010,  was  a  multi-center  study 
evaluating  the  safety  and  efficacy  of  investigational  therapies  combined  with  early  treatment  in  women  with  newly 
diagnosed, locally advanced breast cancer. The results of this trial demonstrated that the change of measurable ctDNA 
from positive to negative during neoadjuvant treatment predicted therapeutic response, while failure to clear ctDNA after 
neoadjuvant treatment correlated with poor clinical outcomes. ctDNA levels were also associated with disease burden as 
determined by imaging. 

We are currently conducting research across multiple cancer types in collaboration with various cancer centers 
and pharmaceutical companies. For example, Signatera has been selected as the MRD test to be used in the Japan arm of 
the CIRCULATE-IDEA trial to evaluate ctDNA-guided treatment strategies for patients with Stage II-III colon cancer. If 
successful, this trial could result in the adoption of MRD testing into current medical practice as well as reimbursement of 
MRD testing in Japan. In addition, we have launched BESPOKE CRC, a nationwide, multi-center, 1,000-patient registry 

12 

study for patients diagnosed with Stage II-III colorectal cancer. The objective of the BESPOKE CRC study is to measure 
the impact of Signatera test results on changes in treatment decisions and clinical outcomes. 

Altera 

We  are  now  expanding  our  efforts  in  oncology  into  therapy  selection,  which  based  our  internal  estimates 
represents a $6 billion market opportunity. We have launched Altera, a tissue based comprehensive genomic profiling test 
that provides insight into genomic alterations and biomarkers found in a patient’s tumor, supporting treatment decisions 
and therapy selection by prioritizing potentially beneficial therapies based on the patient’s tumor biomarkers and cancer 
type. Altera can be ordered as a stand-alone test, as well as in conjunction with our Signatera MRD test to combine therapy 
selection with ongoing monitoring.  

Organ Health 

We began commercializing our first offering in organ health in 2020, with the launch of our Prospera test to 
assess active rejection in patients who have undergone kidney transplantation by measuring the fraction of dd-cfDNA in 
the recipient's blood, which can spike relative to background cfDNA when the transplanted organ is injured due to immune 
rejection.  The  current  tools  for  assessing  organ  transplant  rejection  are  either  invasive  (biopsies)  or  inaccurate  (serum 
creatinine), resulting in an unmet need for better diagnostic tools to monitor for allograft rejection and improve patient 
management  and  outcomes.  Many  patients  are  still  subjected  to  unnecessary  biopsies,  while  other  patients  remain 
undiagnosed in the case of subclinical rejection, which can increase the risk of graft failure. Our Prospera test is designed 
for use by physicians to help rule in or rule out active rejection when evaluating the need for diagnostic testing or the 
results  of  an  invasive  biopsy,  and  thereby  potentially  lowering  the  overall  costs  associated  with  transplant  care  and 
improving graft  survival. We  received  a final  Medicare  local  coverage determination for  Prospera  in  December 2019, 
covering all kidney transplant recipients, including those with multiple kidney transplants. Based on our internal estimates, 
we believe the total addressable market in the United States for tests such as ours that assess kidney transplant rejection is 
over $2 billion. 

Our  clinical  validation  study,  conducted  in  collaboration  with  the  University  of  California,  San  Francisco,  a 
recognized  leader  in  transplantation  care,  and  published  in  the  Journal  of  Clinical  Medicine,  demonstrated  strong 
performance of our mmPCR technology for detecting active rejection in patients with kidney transplants. In the blinded, 
retrospective  study,  we  leveraged  our  SNP  technology  to  measure  dd-cfDNA  levels  in  plasma  samples  from  kidney 
transplant patients, including patients experiencing active rejection. Our assay demonstrated 89% sensitivity in detecting 
active rejection, with specificity of 73%, based on a cutoff of 1% dd-cfDNA. The assay performed particularly well in 
detecting T-cell mediated rejection (TCMR) and subclinical rejection, both of which we believe are areas of unmet need. 

In an analytical validation study published in the February 2019 issue of Transplantation, our assay demonstrated 
superior precision, up to 5 times better than the competing dd-cfDNA assay. Precision is a measure of the test’s ability to 
produce the same result when a single sample is tested repeatedly. This study also included donor-recipient pairs that were 
related, such as parents or siblings, as well as those that were not related. This is significant because an estimated 52% of 
live kidney donations are from a biological relative of the patient, but it is technically challenging to differentiate between 
DNA  patterns  of  close  relatives.  We  were  able  to  achieve  a  high  degree  of  accuracy  in  these  challenging  cases  by 
leveraging our experience with SNP-based methods in the reproductive health setting. 

We  are  currently  enrolling  participants  in  our  ProActive  registry  study,  one  of  the  industry’s  largest  known 
prospective studies to date incorporating dd-cfDNA testing into medical management of organ transplant recipients. The 
study is expected to enroll 3,000 kidney transplant patients from the time of surgery, and will measure changes in biopsy 
usage and clinical outcomes based on physician-directed use of the Prospera test to rule in or rule out active rejection. The 
study protocol calls for most patients to be followed for three years, while a subset of high-risk patients will be studied up 
to five years after transplantation. We have also been selected to participate in a global, prospective multicenter study on 
collaboration  with  Molecular  Microscope  Diagnostic  System,  in  which  300  patients  will  be  evaluated  on  the  basis  of 
clinical  information,  cfDNA  measures,  biopsies,  molecular  microscope,  evaluations,  and  donor-specific  antibodies  to 
assess the potential benefits of integrated data analysis in managing kidney transplantation.   

13 

We believe we are also uniquely positioned to benefit potential organ transplant patients with cancer or a history 
of cancer, for whom it can be difficult to receive a transplant due to the uncertain risk of cancer recurrence as well as the 
increased risk of new or recurring cancers resulting from the immune-suppressing medications required to avoid rejection 
of the transplanted organ. We are planning several studies to understand how our Signatera and Prospera tests can be used 
to improve decision-making and care for these patients. 

Constellation 

Our Constellation software forms the core of our cloud-based distribution model. Through this model, we have 
been able to expand access to our molecular and bioinformatics capabilities worldwide, enabling laboratories, under a 
license from us, to run the molecular workflows themselves and then access our computation-intensive bioinformatics 
algorithms through Constellation, which runs in the cloud, to analyze the results. We currently have licensing contracts 
with various laboratories in the United States and internationally who are using our Constellation platform commercially 
in NIPT and in prenatal paternity testing, and we plan to expand this distribution model to other products in the future. We 
also leverage Constellation to perform our internal commercial laboratory activities and research and development of our 
products. 

We  have  received  CE  Marks  from  the  European  Commission  for  our  Constellation  software  and  for  the  key 
reagents  that  our  laboratory  licensees need to  run  their portion  of  the Panorama  test  prior  to  accessing our  algorithms 
through Constellation. These CE Marks enable us to offer Constellation in the European Union and other countries that 
accept  a  CE  Mark.  We  are  pursuing  other  regulatory  approvals,  as  needed,  to  allow  the  international  roll  out  of 
Constellation in regions that do not accept a CE Mark. 

Commercial Capabilities  

We have established a broad distribution channel, comprising our direct sales efforts and, for our women’s health 
products, a worldwide network of over 100 laboratory and distribution partners. Our own direct sales force and managed 
care teams anchor our commercial engagement with physicians, laboratory partners, and payers, and sell directly to MFMs, 
OB/GYNs, physicians or physician practices, IVF centers, transplant centers, or integrated health systems.  

Where possible, we aim to maximize sales opportunities by educating the physician practices on the benefits of 
combining complementary tests from our portfolio of products. For example, in women’s health, Panorama NIPT, our 
Panorama microdeletions panel, and Horizon together can provide valuable information for pregnant women who have 
not had a CS test at the time they are ready to have an NIPT performed; these tests can all be run using one blood draw 
from  the  mother  and  can  be  ordered  on  one  requisition  form  and  with  one  shipment  of  the  patient’s  samples  by  the 
physician. Also, because of the importance and demand for screening for 22q11.2 deletion syndrome, we have included 
that feature as part of our basic Panorama panel, unless the patient or physician ordering the test opts out of the 22q11.2 
deletion syndrome screen. In the year ended December 31, 2020, approximately three-quarters of customers who ordered 
the basic Panorama panel directly from us also ordered screening for 22q11.2 deletion syndrome or the full microdeletions 
panel, and approximately one-third of customers who ordered Panorama directly from us also ordered Horizon carrier 
screening.  

In  addition  to  our  sales  force,  we  market  to  physicians  through  clinical  journals,  educational  webinars, 
conferences, tradeshows and e-mail marketing campaigns. While we currently do not sell directly to patients, we do engage 
in brand awareness campaigns directed at patients to highlight our products. Our marketing and medical science liaison 
teams work extensively with key opinion leaders in the reproductive health, oncology and organ health fields.  

Our  partners’  capabilities  augment  our  direct  sales  capabilities,  and  where  we  have  identified  laboratory  or 
distribution partners who share our focus on premium quality and service, we also contract with them to distribute our 
tests. In NIPT, we have partnered with leading academic and commercial laboratories and hospital systems in the United 
States  to  capitalize  on  their  relationships  with  MFMs  and  OB/GYNs,  large  distribution  capabilities,  and  commercial 
infrastructure. These distribution partners also frequently have in-network contracts with key third-party payers. As of 
December 31, 2020, we had in-network contracts with insurance providers that accounted for approximately 214 million 

14 

covered lives in the United States. We continue our efforts to increase the number of our in-network contracts with payers. 
Our target market for NIPT is a much smaller subset of these covered lives, because it excludes men, children and post-
menopausal women who would not  be users  of  the  majority  of our products.  Outside  of  the United  States,  where our 
products are sold in over 80 countries, we currently sell predominantly through partner laboratories.  

Enhanced User Experience  

NateraCore  is  our  suite  of  resources  designed  to  enhance  the  patient  and  provider  experience.  Through  this 
platform, we provide patient and provider educational materials, information about insurance coverage and test costs, test 
and phlebotomy ordering capabilities, test reporting, and next steps, in each case as applicable to a particular patient or 
test. These resources make available a completely remote testing option for patients, fulfilled through our online tools 
combined with a nationwide mobile phlebotomy network. This capability has proven to be especially important during the 
COVID-19  pandemic,  enabling  continuity  of  care  for  all  patients  and  particularly  for  those  who  may  be 
immunocompromised or immune-suppressed.  

For example, women’s health patients logging on to our patient portal can access and manage testing information, 
results  and  services  throughout  their  experience,  from  pre-test  to  post-test.  We  have  also  created  provider  portals  for 
clinicians in each of women’s health, oncology and organ health, which enable physicians to easily complete various tasks 
online  such  as  ordering  and  tracking  tests,  managing  patient  consents  and  results,  accessing  billing  and  other 
documentation, connecting with genetic counselors and other support, and ordering supplies and educational materials. 
We  also  provide  a  service  to  integrate  with  our  customers’  Electronic  Medical  Records,  or  EMR,  systems  to  provide 
physicians a seamless experience of ordering tests and reviewing patient test results directly through their EMR systems. 

We  have  a  team  of  board-certified  genetic  counselors  to  support  patients  with  pre-  and  post-test  genetic 

information sessions, and physicians should they have any questions or require any guidance in interpreting the results.  

We have a network of over 2,000 phlebotomy centers across the United States. We also offer mobile phlebotomy 

services whereby a patient can request and schedule a phlebotomist visit at the patient’s home or office. 

Key Relationships  

Illumina 

We are party to a supply agreement with Illumina, Inc., or Illumina, for the supply of Illumina genetic sequencing 
instruments and reagents for NIPT, oncology and transplant diagnostic testing. For oncology, we also received rights to 
develop and sell in vitro diagnostic kits and services worldwide, in exchange for which we agreed to make certain milestone 
and royalty payments to Illumina. During the term of the supply agreement, which expires in May 2030, Illumina has 
agreed to supply us with sequencers, reagents and other consumables for use with the Illumina sequencers, and we must 
provide a forecast, on a monthly basis, detailing our needs for certain of the Illumina products. The first four calendar 
months of each forecast are binding and the fourth month can vary by only up to 25% more or less than what was forecasted 
for that month in the prior month's forecast. In addition, during each calendar quarter, we must spend a minimum amount 
on reagents under this agreement. We and Illumina have agreed on prices for the sequencers and reagents, for which we 
are entitled to certain discounts based on total spend and other factors. Illumina has the right to adjust these prices under 
certain conditions. In addition, we must pay a fee to Illumina for each clinical NIPT test that we perform using Illumina 
reagents. Illumina is currently the sole supplier of our sequencers and related reagents for many of our tests, along with 
certain hardware and software. We are not bound to use exclusively Illumina's sequencing instruments and reagents for 
conducting our sequencing, but if we use other sequencing instruments and reagents for more than specified percentages 
of our total NIPT clinical volume, we may no longer be entitled to discounts from Illumina.  

Illumina may terminate the agreement upon the following circumstances: if we materially breach the agreement 
and fail to cure such breach within 30 days after receiving written notice of such breach, and only after complying with 
additional notice provisions; if we become the subject of certain bankruptcy or insolvency proceedings; or in connection 

15 

with certain changes of control of Natera. Illumina also has the right to terminate: (a) certain rights under the agreement 
upon two years’ prior notice; and (b) our rights with respect to IVDs if we have not obtained a premarket approval for at 
least one IVD from the United States Food and Drug Administration by June 8, 2026, unless we are diligently pursuing 
approval of an active PMA application at such time. We may terminate the agreement: if Illumina materially breaches the 
agreement  and  fails  to  cure  such  breach  within  30  days  after  receiving  written  notice  of  such  breach,  and  only  after 
complying  with  additional  notice  provisions;  if  Illumina  becomes  the  subject  of  certain  bankruptcy  or  insolvency 
proceedings; in connection with certain supply failures by Illumina; or for convenience with four months written notice. 
The agreement also contains use limitations, representations and warranties, indemnification, limitations of liability and 
other provisions.  

Competition  

The  markets  in  which  we  operate  are  characterized  by  innovation  and  rapid  change,  and  we  primarily  face 
competition from various companies that develop and commercialize molecular diagnostic tests in reproductive health, 
oncology, and organ transplant rejection. Our competitors in the NIPT space include Sequenom, Inc., or Sequenom, which 
was acquired by Laboratory Corporation of America Holdings, or LabCorp; Illumina, through its subsidiary Verinata; 
Ariosa, Inc., a subsidiary of F. Hoffman La-Roche Ltd, or Roche; Myriad Genetics, Inc., which acquired Counsyl, Inc.; 
Invitae Corp.; Quest Diagnostics Incorporated, or Quest; Premaitha Health PLC; BGI; Progenity, Inc., or Progenity; Bio-
Reference, a business unit of OPKO Health, Inc. and which was previously a laboratory distribution partner of ours; NxGen; 
BillionToOne Inc.; PerkinElmer Inc.; and Mount Sinai Genomics, Inc. d/b/a Sema4. We also compete against companies 
providing carrier screening tests such as LabCorp; Myriad Genetics, Inc.; Sema4; Invitae Corp.; Progenity; Recombine 
Inc.; Quest; GeneDx, Inc., a subsidiary of Bio-Reference; and GenPath Diagnostics, a business unit of Bio-Reference. 
Each of these companies offers comprehensive CS panels. 

In the field of ctDNA-based MRD assessment and recurrence surveillance, we compete with various companies 
that  offer  or  seek  to  offer  competing  solutions,  such  as  Roche  Diagnostics,  Guardant  Health,  Inc.,  Adaptive 
Biotechnologies, Personal Genome Diagnostics, Inc., Exact Sciences Corp., Inivata, Inc., and ArcherDX, Inc., which has 
been acquired by Invitae Corp., one of our primary competitors in both NIPT and carrier screening.  

In organ health, our competitors include CareDx, Inc. and Eurofins Viracor, Inc.  

We expect additional competition as other established and emerging companies enter these markets, including 
through business combinations, and as new tests and technologies are introduced. These competitors could have greater 
technological, financial, reputational and market access resources than us.  

We believe the principal competitive factors in our molecular diagnostic testing markets include the following: 

• 

• 

• 

• 

• 

• 

• 

test performance, as demonstrated in clinical and analytical studies and clinical trials as well as in 
commercial experience; 

comprehensiveness of coverage and ease of use; 

value of product offerings, including pricing and impact on other healthcare spending;    

scope and extent of reimbursement and payer coverage;   

effectiveness of sales and marketing efforts;   

breadth of distribution of products and partnership base;   

reputation among patients and providers for development and introduction of new, innovative products;   

16 

 
 
 
 
 
 
 
• 

• 

• 

• 

operational execution, including test turn-around time and test failures;    

key opinion leader support;   

brand awareness; and   

ease of integration for laboratories, including for cloud-based distribution models. 

Specific market share data regarding our products is not publicly available, and consumers may choose to use 
competing products for a variety of reasons, including lower cost. We believe, however, that we compete favorably in the 
reproductive health market on the basis of several factors, particularly test performance, comprehensiveness of coverage 
of diseases, ability to conveniently test for multiple conditions, value of product offerings and effectiveness of sales and 
marketing efforts. In oncology, we believe that the sensitivity and specificity of our personalized, tumor-informed assay 
for MRD compares favorably to static-panel based MRD tests in detecting residual disease or recurrence after treatment, 
and in impacting treatment decisions.  

Intellectual Property  

Our success and ability to compete depend in part on securing and preserving enforceable patent, trade secret, 
trademark  and  other  intellectual  property  rights;  operating  without  having  competitors  infringe,  misappropriate  or 
otherwise  circumvent  these  rights;  operating  without  infringing  the  proprietary  rights  of  others;  and  obtaining  and 
maintaining licenses for technology development and/or product commercialization. As of December 31, 2020, we held 
100 issued U.S. and foreign patents, which expire between November 2026 and December 2036, and over 100 pending 
U.S. and foreign patent applications. Our patents and patent applications relate generally to molecular diagnostics, and 
more  specifically  to  biochemical  and  analytical  techniques  for  obtaining  and  analyzing  genetic  information  to  detect 
genetic abnormalities in relatively small complex samples, such as cell free fetal DNA or circulating tumor DNA. We 
intend to seek patent protection as we develop new technologies and products in this area. 

We are or have recently been engaged in patent infringement lawsuits and other intellectual property disputes 
against various competitors in each of the industries in which we operate, some of which are infringement claims against 
us  and  some  of  which  are  claims  we  have  asserted  against  third  parties,  as  discussed  in  “Note 8—Commitments  and 
Contingencies—Legal Proceedings” in the Notes to Consolidated Financial Statements. We may become subject to and/or 
initiate future intellectual property litigation as our product portfolio, and the level of competition in our industry segments, 
grow. The field of molecular diagnostics is complex and rapidly evolving, and we expect that we and others in our industry 
will continue to be subject to third-party infringement claims. 

Reimbursement  

We receive reimbursement for our tests from commercial third-party payers and from government health benefits 
programs  such  as  Medicare  and  Medicaid.  Laboratory  tests,  as  with  most  other  healthcare  services,  are  classified  for 
reimbursement purposes under a coding system known as Current Procedure Terminology, or CPT, which we and our 
customers must use to bill and receive reimbursement for our diagnostic tests. These CPT codes are associated with the 
particular test that we have provided to the patient. Once the American Medical Association establishes a CPT code, the 
Centers for Medicare & Medicaid Services, or CMS, establishes payment levels and coverage rules under Medicare while 
private payers establish rates and coverage rules independently. For most of the tests performed for Medicare or Medicaid 
beneficiaries,  laboratories  are  required  to  bill  Medicare  or  Medicaid  directly,  and  to  accept  Medicare  or  Medicaid 
reimbursement as payment in full. Prior to 2015, CMS had implemented a set of CPT codes without a fee schedule for 
most codes specific to NIPTs; a CPT code specific to NIPT for aneuploidies has been effective since January 2015, and a 
CPT code for microdeletions has been effective since January 2017. CMS has established a pricing benchmark of $802 
for aneuploidy and microdeletions testing. In addition, a CPT code for expanded carrier screening tests went into effect in 
January 2019, for which CMS has established a pricing benchmark of approximately $2,450.  

17 

 
 
 
We currently submit for reimbursement using CPT codes based on the guidance of coding experts and outside 
legal counsel. There is a risk that these codes may be rejected or withdrawn or that payers will seek refunds of amounts 
that they claim were inappropriately billed to a specific CPT code. We do not currently have a specific CPT code assigned 
for all of our tests, and there is a risk that we may not be able to obtain specific codes for such tests, or if obtained, we may 
not be able to negotiate favorable rates for one or more of these codes. In particular, while we have obtained a CPT code 
for microdeletions and CMS has set a price for microdeletions testing, we have experienced low average reimbursement 
rates for microdeletions testing under this code, and we expect that this code will continue to cause our microdeletions 
reimbursement to remain low, at least in the near term, because third-party payers are declining to reimburse under the 
new code or reimbursing at a much lower rate than we had previously received before the CPT code was established. The 
reimbursement rates for our broader Horizon screening panel have also declined as a result of the new CPT code becoming 
effective in 2019, as carrier screening tests that had previously been reimbursed on a per-condition basis may be reimbursed 
as a combined single panel instead of as multiple individual tests.  

We  believe  that  growing  recognition  from  professional  societies  of  the  importance  of  microdeletions  testing, 
combined with the performance of our microdeletions test and additional validation data from our SMART study that we 
expect to publish on the sensitivity and specificity of our tests, will help drive broader reimbursement in the future. 

In making coverage determinations, third-party payers often rely on practice guidelines issued by professional 
societies.  NIPT  has  received  positive  coverage  determinations  for  high-risk  pregnancies  and  in  such  instances  are 
reimbursed by most commercial payers, including United Healthcare, AETNA, Anthem, Humana, CIGNA and others. 
The use of NIPT for average-risk pregnancies has not historically been well reimbursed by payers; however, professional 
societies now generally acknowledge that NIPT is the most sensitive screening option for, and/or are generally supportive 
of, NIPT in average-risk pregnancies, in addition to high-risk pregnancies. There has been a significant increase in the 
number of  commercial  third-party  payers, representing  approximately 95% of  commercial  covered lives  in  the  United 
States, that cover the use of Panorama in the average-risk population, as well as an increasing number of state Medicaid 
payers with a positive coverage determination for NIPT for average-risk pregnancies. 

As of December 31, 2020 we and our laboratory partners had in-network contracts with insurance providers that 
accounted for approximately 214 million covered lives in the United States. Our target market for NIPT is a much smaller 
subset of these covered lives, because it excludes men, children and post-menopausal women who would not be users of 
our products. 

Government Regulations  

Our business is subject to and impacted by extensive and frequently changing laws and regulations in the United 
States (at both the federal and state levels) and internationally. These laws and regulations include regulations particular 
to our business and laws and regulations relating to conducting business generally (e.g., export controls laws, U.S. Foreign 
Corrupt  Practices  Act  and  similar  laws  of  other  jurisdictions).  We  also  are  subject  to  inspections  and  audits  by 
governmental agencies. Set forth below are highlights of certain key regulatory schemes applicable to our business. 

FDA  

In the United States, medical devices are subject to extensive regulation by the Food and Drug Administration, 
or FDA, under the Federal Food, Drug, and Cosmetic Act, or FDC Act, and its implementing regulations, and other federal 
and state statutes and regulations. The laws and regulations govern, among other things, medical device development, 
testing, labeling, storage, premarket clearance or approval, advertising and promotion and product sales and distribution. 
To be commercially distributed in the United States, medical devices must receive from the FDA prior to marketing, unless 
subject to an exemption, clearance of a premarket notification, or 510(k), premarket approval, or a PMA, or a de novo 
authorization. 

IVDs  are  a  type  of  medical  device  that  can  be  used  in  the  diagnosis  or  detection  of  diseases  or  conditions, 
including assessment of state of health, through collection, preparation and examination of specimens from the human 
body. IVDs can be used to detect the presence of certain chemicals, genetic information or other biomarkers related to 

18 

health or disease. IVDs include tests for disease prediction, prognosis, diagnosis, and screening (e.g., carrier screening).  
A subset of IVDs is what are known as analyte specific reagents, or ASRs. An ASR is a single reagent that, through specific 
binding  or  chemical  reaction  with  substances  in  a  specimen,  is  intended  for  use  in  a  diagnostic  application  for  the 
identification and quantification of an individual chemical substance in biological specimens. Most ASRs are exempt from 
the premarket review processes but must comply with some quality system regulation, or QSR, provisions and other device 
requirements. 

The FDC Act classifies medical devices into one of three categories based on the risks associated with the device 
and the level of control necessary to provide reasonable assurance of safety and effectiveness. Class I devices are deemed 
to be low risk and are subject to the fewest regulatory controls. Many Class I devices are exempt from FDA premarket 
review requirements. Class II devices, including some software products to the extent that they qualify as a device, are 
deemed  to  be  moderate  risk,  and  generally  require  clearance  through  the  premarket  notification,  or  510(k)  clearance, 
process. Class III devices are generally the highest risk devices and are subject to the highest level of regulatory control to 
provide reasonable assurance of the device's safety and effectiveness. Class III devices typically require a PMA by the 
FDA before they are marketed. A clinical trial is almost always required to support a PMA application and is sometimes 
required for 510(k) clearance. All clinical studies of investigational devices must be conducted in compliance with any 
applicable  FDA  and  Institutional  Review  Board  requirements.  Devices  that  are  exempt  from  FDA  premarket  review 
requirements must nonetheless comply with post-market general controls as described below, unless the FDA has chosen 
otherwise. 

510(k)  clearance  pathway.  To  obtain  510(k)  clearance,  a  manufacturer  must  submit  a  premarket  notification 
demonstrating to the FDA's satisfaction that the proposed device is substantially equivalent to a previously 510(k)-cleared 
device  or  to  a  device  that  was  in  commercial  distribution  before  May  28,  1976  for  which  the  FDA  has  not  called  for 
submission of a PMA application. The previously cleared device is known as a predicate. The FDA's 510(k) clearance 
pathway usually takes from three to 12 months from submission, but it can take longer, particularly for a novel type of 
product. In addition, the COVID-19 pandemic has resulted in significant workload increases within the Center for Devices 
and Radiological Health that could affect 510(k) review timelines. 

PMA  pathway.  The  PMA  pathway  requires  proof  of  the  safety  and  effectiveness  of  the  device  to  the  FDA's 
satisfaction. The PMA pathway is costly, lengthy, and uncertain. A PMA application must provide extensive preclinical 
and clinical trial data as well as information about the device and its components regarding, among other things, device 
design, manufacturing, and labeling. As part of its PMA review process, the FDA will typically inspect the manufacturer's 
facilities for compliance with QSR requirements, which impose elaborate testing, control, documentation, and other quality 
assurance procedures. The PMA review process typically takes one to three years from submission but can take longer, 
including, as noted above, due to delays resulting from the COVID-19 pandemic.  

De  novo  pathway.  If  no  predicate  device  can  be  identified,  a  device  is  automatically  classified  as  Class  III, 
requiring a PMA application. However, the FDA can reclassify, or use "de novo classification," for a device for which 
there was no predicate device if the device is low- or moderate-risk. If the device is deemed Class II, the FDA will identify 
"special controls" that the manufacturer must implement, which often include labeling and other restrictions. Subsequent 
applicants can rely upon the de novo product as a predicate for a 510(k) clearance, unless FDA exempts subsequent devices 
from the need for a 510(k). The de novo route is less burdensome than the PMA process, but FDA issued a proposed 
regulation in 2018 that, if adopted as written, could increase the regulatory burden in obtaining a de novo authorization. A 
device company can ask the FDA at the outset if the de novo route is available and submit the application as one requesting 
de novo classification. The de novo route has been used for many IVD products. The FDA has indicated to us that our 
software that enables our cloud-based distribution model may be appropriate for review under the de novo classification 
process. However, the FDA has not committed to this position and may take a different position in the future. 

Post-market general controls. After a device, including a device exempt from FDA premarket review, is placed 
on the market, numerous regulatory requirements apply. These include: the QSR, labeling regulations, registration and 
listing, the Medical Device Reporting regulation (which requires that manufacturers report to the FDA if their device 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), and the Reports of Corrections and Removals regulation (which requires 

19 

manufacturers to report to the FDA corrective actions made to products in the field, or removal of products once in the 
field if such actions were initiated to reduce a risk to health posed by the device or to remedy a violation of the FDC Act). 
Depending on the severity of the legal violation that led to correction or removal, the FDA may classify the manufacturer’s 
action as a recall. 

The FDA enforces compliance with its requirements through inspection and market surveillance. If the FDA finds 
a violation, it can institute a wide variety of actions, ranging from an untitled or public warning letter to enforcement 
actions such as fines, injunctions, and civil penalties; recall or seizure of products; operating restrictions, partial suspension 
or total shutdown of production; refusing requests for 510(k) clearance or PMA approval of new products; withdrawing 
510(k)  clearance  or  PMAs  already  granted;  and  criminal prosecution.  For  additional  information,  see  "Risk  Factors—
Reimbursement and Regulatory Risks Related to Our Business."  

Research use only. Research use only, or 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. Our LDTs use instruments and reagents labeled as RUO.  

Laboratory-developed tests. The FDA considers LDTs to be tests that are designed, developed, validated and 
used within a single laboratory. The FDA historically has taken the position that it has the authority to regulate such tests 
as medical devices under the FDC Act but has for the most part exercised enforcement discretion and has not required 
clearance or approval of LDTs prior to marketing.  

In  2014,  the  FDA  issued  two  draft  guidance  documents  regarding  oversight  of  LDTs.  These  draft  guidance 
documents proposed more active review of LDTs. The draft guidances were the subject of considerable controversy, and 
in 2016, the FDA announced that it would not be finalizing the 2014 draft guidance documents. Subsequently, in 2017, 
the FDA issued a discussion paper which laid out elements of a possible revised future LDT regulatory framework, but 
did not establish any regulatory requirements.  

The FDA’s efforts to regulate LDTs have prompted the drafting of legislation governing diagnostic products and 
services that has sought to substantially revamp the regulation of both LDTs and IVDs. Congress may still act to provide 
further direction to the FDA on the regulation of LDTs and substantially modify the regulation of IVDs.  

In August 2020, the Department of Health and Human Services, or HHS, announced that FDA will not require 
premarket review of LDTs absent notice-and-comment rulemaking, and rescinded FDA guidance documents and other 
informal statements concerning premarket review of LDTs. The HHS announcement did not define the term LDT. In an 
accompanying FAQ document, HHS stated that, while LDTs are not subject to premarket review, FDA may still regulate 
LDTs under the Public Health Service Act. We believe that other than the RUO version of Signatera, all of the tests we 
currently offer, including Panorama, meet the definition of LDTs, as they have been designed, developed, and validated 
for use in a single CLIA-certified laboratory. If our tests are LDTs, then, consistent with the HHS policy announcement, 
FDA may not require premarket review. Furthermore, if our tests are LDTs, then, based on FDA’s historical approach, we 
believe they will be subject to FDA enforcement discretion. 

Clinical Laboratory Improvement Amendments of 1988 and State Regulation  

As a clinical laboratory, we are required to hold certain federal and state licenses, certifications and permits to 
conduct  our  business.  As  to  federal  certifications,  in  1988,  Congress  passed  the  Clinical  Laboratory  Improvement 
Amendments of 1988, or CLIA, establishing more rigorous quality standards for all commercial laboratories that perform 
testing on human specimens for the purpose of providing information for the diagnosis, prevention, or treatment of disease 
or the assessment of the health or impairment of human beings. CLIA requires such laboratories to be certified by the 
federal government and mandates compliance with various operational, personnel, facilities administration, quality and 

20 

proficiency testing requirements intended to ensure the accuracy, reliability and timeliness of patient test results. CLIA 
certification is also a prerequisite to be eligible to bill state and federal healthcare programs, as well as many commercial 
third-party payers, for laboratory testing services. 

Our laboratories located in Austin, Texas and in San Carlos, California are CLIA certified, and must comply with 
all applicable CLIA requirements. If a clinical laboratory is found to be out of compliance with CLIA standards, CMS 
may impose sanctions, limit or revoke the laboratory’s CLIA certificate (and prohibit the owner, operator or laboratory 
director  from  owning,  operating,  or  directing  a  laboratory  for  two  years  following  license  revocation),  subject  the 
laboratory to a directed plan of correction, on-site monitoring, civil monetary penalties, civil actions for injunctive relief, 
criminal penalties, or suspension or exclusion from the Medicare and Medicaid programs. 

CLIA provides that a state may adopt laboratory licensure requirements and regulations that are more stringent 
than  those  under  federal  law,  and  requires  compliance  with  such  laws  and  regulations.  A  number  of  states  have 
implemented their own more stringent laboratory regulatory requirements. State laws may require the laboratory to obtain 
state  licensure  and/or  laboratory  personnel to  meet  certain  qualifications,  specify  certain  quality  control  procedures  or 
facility requirements, or prescribe record maintenance requirements. Moreover, several states impose the same or similar 
state requirements on out-of-state laboratory testing specimens collected or received from, or test results reported back to, 
residents within that state. Therefore, we are required to meet certain laboratory licensing requirements for those states in 
which we offer services or from which we accept specimens and that have adopted regulations beyond CLIA. For more 
information  on  state  licensing  requirements,  see  “—California  Laboratory  Licensing”,  “—New  York  Laboratory 
Licensing,” and “—Other State Laboratory Licensing Laws.” 

Our laboratories have each also been accredited by the College of American Pathologists, or CAP, which means 
that our laboratories have been certified as following CAP standards and guidelines in operating the laboratory facility and 
in performing tests that ensure the quality of our test results.  

California Laboratory Licensing  

In addition to federal certification requirements for laboratories under CLIA, we are required under California 
law to maintain a California state license for our San Carlos clinical laboratory and comply with California state laboratory 
laws and regulations. Similar to the federal CLIA regulations, the California state laboratory laws and regulations establish 
standards for the operation of a clinical laboratory and performance of test services, including the education and experience 
requirements  of  the  laboratory  director  and  personnel  (including  requirements  for  documentation  of  competency), 
equipment validations, and quality management practices. All testing personnel must maintain a California state license 
or be supervised by licensed personnel. 

Clinical  laboratories  are  subject  to  both  routine  and  complaint-initiated  on-site  inspections  by  the  state.  If  a 
clinical laboratory is found to be out of compliance with California laboratory standards, the California Department of 
Public Health, or CAPH, may suspend, restrict or revoke the California state laboratory license to operate the clinical 
laboratory  (and  exclude  persons  or  entities  from  owning,  operating,  or  directing  a  laboratory  for  two  years  following 
license revocation), assess civil money penalties, and/or impose specific corrective action plans, among other sanctions. 
Clinical laboratories must also provide notice to CAPH of any changes in the ownership, directorship, name or location of 
the laboratory. Failure to provide such notification may result in revocation of the state license and sanctions under the 
CLIA certificate. Any revocation of a CLIA certificate or exclusion from participation in Medicare or Medicaid programs 
may result in suspension of the California state laboratory license. 

New York Laboratory Licensing  

Because we test specimens in our San Carlos, California laboratory originating from, and return test results to, 
New York State, our San Carlos clinical laboratory is required to obtain a New York state laboratory permit and comply 
with  New  York  state  laboratory  laws  and  regulations.  We  maintain  a  valid  permit  in  the  State  of  New  York  for  the 
molecular genetic testing services furnished by our San Carlos clinical laboratory. The New York state laboratory laws, 
regulations and rules are equal to or more stringent than the CLIA regulations and establish standards for the operation of 

21 

a clinical laboratory and performance of test services, including education and experience requirements of a laboratory 
director  and  personnel,  physical  requirements  of  a  laboratory  facility,  equipment  validations,  and  quality  management 
practices. The laboratory director(s) must maintain a Certificate of Qualification issued by the New York State Department 
of Health, or DOH, in the permitted test categories. 

Our San Carlos clinical laboratory is subject to proficiency testing and on-site survey inspections conducted by 
the Clinical Laboratory Evaluation Program, or CLEP, under the DOH. If a laboratory is found to be out of compliance 
with New York’s CLEP standards, the DOH, may suspend, limit, revoke or annul the New York laboratory permit, censure 
the holder of the license or assess civil money penalties. Statutory or regulatory noncompliance may result in a laboratory’s 
operator,  owners  and/or  laboratory  director  being  found  guilty  of  a  misdemeanor  under  New  York  law.  Clinical 
laboratories must also provide notice to CLEP of any changes in ownership, directorship, name or location of the laboratory. 
Failure to provide such notification may result in revocation of the state license and sanctions under the CLIA certificate. 
Any revocation of a CLIA certificate or exclusion from participation in the Medicare or Medicaid programs may result in 
suspension of the New York laboratory permit. 

The DOH also must approve each LDT before the test is offered to patients located in New York. Our San Carlos 
clinical laboratory has received approval from New York’s CLEP to offer our Panorama, Horizon, Spectrum, Anora non-
invasive prenatal paternity, and Prospera tests.  

Other State Laboratory Licensing Laws 

In addition to New York and California, certain other states require licensing of out-of-state laboratories under 
certain circumstances. We have obtained licenses in the states that we believe require us to do so, and believe we are in 
compliance  with  applicable  state  laboratory  licensing  laws.  The  State  of  Texas  does  not  impose  state  licensure  or 
registration requirements upon an independent laboratory facility outside of maintaining CLIA certification.  

Potential  sanctions  for  violation  of  state  statutes  and  regulations  can  include  significant  monetary  fines,  the 
rejection of license applications, the suspension or loss of various licenses, certificates and authorizations, and in some 
cases criminal penalties, which could harm our business. CLIA does not preempt state laws that have established laboratory 
quality standards that are more stringent than federal law. 

State Genetic Testing Laws  

Many states have implemented genetic testing and privacy laws imposing specific patient consent requirements 
and  protecting  test  results.  In  some  cases,  we  are  prohibited  from  conducting  certain  tests  without  appropriate 
documentation  of  patient  consent  by  the  physician  ordering  the  test.  As  discussed  in  more  detail  in  “Risk  Factors—
Reimbursement and Regulatory Risks Related to our Business--If the validity of an informed consent from a patient intake 
for  Panorama  or  our  other  tests  is  challenged,  we  could  be  precluded  from  billing  for  such  testing,  forced  to  stop 
performing such tests, or required to repay amounts previously received, which would adversely affect our business and 
financial results,” while we rely on physicians and our partners to obtain the required patient consent to perform testing, 
such  consents,  or  our  and  our  partners’  compliance  with  applicable  laws  and  regulations,  could  be  challenged. 
Requirements of these laws and penalties for violations vary widely.  

HIPAA and Other Privacy Laws  

The privacy and security regulations under the Health Insurance Portability and Accountability Act of 1996, or 
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, 
establish uniform standards governing the conduct of certain electronic healthcare transactions and require certain entities, 
called covered entities, to comply with standards that include the privacy and security of protected health information, or 
PHI. HIPAA further requires business associates of covered entities—independent contractors or agents of covered entities 
that have access to protected health information in connection with providing a service to or on behalf of a covered entity—
to  enter  into  business  associate  agreements  with  the  covered  entity  and  to  safeguard  the  covered  entity’s  PHI  against 

22 

improper use and disclosure. In addition, certain of HIPAA’s  privacy and security standards are directly applicable to 
business associates. 

As a covered entity and as a business associate of other covered entities (with whom we have therefore entered 
into business associate agreements), we have certain obligations regarding the use and disclosure of any PHI that may be 
provided to us, and we could incur significant liability if we fail to meet such obligations or if our business associates fail 
to meet such obligations. Among other things, HITECH imposes civil and criminal penalties against covered entities and 
business associates for noncompliance with privacy and security requirements and authorizes states’ attorneys general to 
file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees 
and costs associated with pursuing federal civil actions. 

As noted above, we are required to comply with HIPAA standards promulgated by the U.S. Department of Health 
and Human Services, or HHS. First, we must comply with HIPAA’s standards for electronic transactions, which establish 
standards for common healthcare transactions, such as claims information, plan eligibility, payment information and the 
use of electronic signatures. We must also comply with the standards for the privacy of individually identifiable health 
information, which limit the use and disclosure of most paper and oral communications, as well as those in electronic form, 
regarding  an  individual’s  past,  present or  future physical or  mental  health or  condition,  or relating  to  the provision of 
healthcare to the individual or payment for that healthcare, if the individual can or may be identified by such information. 
Additionally, we must comply with HIPAA’s security standards, which require us to ensure the confidentiality, integrity 
and availability of all electronic protected health information that we create, receive, maintain or transmit, to protect against 
reasonably  anticipated  threats  or  hazards  to  the  security  of  such  information,  and  to  protect  such  information  from 
unauthorized use or disclosure. 

Various  states  in  the  United  States  have  implemented  similar  restrictive  requirements  regulating  the  use  and 
disclosure of health information and other personally identifiable information that are not necessarily preempted by HIPAA, 
particularly if a state affords greater protection to individuals than HIPAA. For example, in 2020 California enacted the 
California Consumer Privacy Act, which creates new consumer rights relating to the access to, deletion of, and sharing of 
personal information collected by certain businesses that operate in the state. In addition, Massachusetts law requires that 
any company that obtains personal information of any resident of the Commonwealth of Massachusetts implement and 
maintain a security program that adequately protects such information from unauthorized use or disclosure. 

There are also foreign privacy and security laws and regulations that impose restrictions on the access, use and 
disclosure of health information. In particular, the EU’s General Data Protection Regulation, or GDPR, became effective 
in 2018. The GDPR applies not only to organizations within the EU, but also applies to organizations outside of the EU, 
such as Natera, that offer goods or services to EU data subjects or that process or hold personal data of EU data subjects. 
The regulation specifies higher potential liabilities for certain data protection violations, and we anticipate that it will result 
in  a  greater  compliance  burden  for  us  as  we  conduct  our  business,  particularly  through  our  Constellation  cloud-based 
distribution model, in the European Union. Fines for non-compliance can range from the greater of 2% of annual global 
revenues or €10 million, up to the greater of 4% of annual global revenues or €20 million. 

As  a  business  that  operates  both  internationally  and  throughout  the  United  States,  any  unauthorized  use  or 
disclosure of personally identifiable information, even if it does not constitute PHI, by us or our third-party contractors, 
including disclosure due to data theft or unauthorized access to our or our third-party contractors’ computer networks, 
could subject us to costs, fines or penalties that could adversely affect our business and results of operations, including the 
cost of providing notice, credit monitoring and identity theft prevention services to affected consumers.  

Healthcare Fraud and Abuse Laws  

The  federal  Anti-Kickback  Statute  makes  it  a  felony  for  a  provider  or  supplier,  including  a  laboratory,  to 
knowingly and willfully offer, pay, solicit or receive remuneration, directly or indirectly, in order to induce business that 
is  reimbursable  under  any  federal  healthcare  program.  A  violation  of  the  federal  Anti-Kickback  Statute  may  result  in 
imprisonment for up to ten years and/or criminal fines of up to $100,000, civil fines up to $100,000 as well as the potential 
for additional civil monetary penalties, civil assessments resulting from the conduct, and exclusion from participation in 

23 

Medicare, Medicaid and other federal healthcare programs. Although the federal Anti-Kickback Statute applies only to 
federal healthcare programs, a number of states have passed laws substantially similar to the federal Anti-Kickback Statute 
pursuant to which similar types of prohibitions are made applicable to all other health plans and third-party payers. Actions 
which violate the federal Anti-Kickback Statute or similar laws may also involve liability under the Federal False Claims 
Act, which prohibits knowingly presenting or causing to be presented a false, fictitious or fraudulent claim for payment to 
the U.S. Government and can  result in additional penalties and fines. 

Federal and state law enforcement authorities scrutinize arrangements between healthcare providers and potential 
referral  sources  to  ensure  that  the  arrangements  are  not  designed  as  a  mechanism  to  induce  patient  care  referrals  and 
opportunities.  Law  enforcement  authorities,  courts  and  Congress  have  demonstrated  a  willingness  to  look  behind  the 
formalities of a transaction to determine the underlying purpose of payments between healthcare providers and actual or 
potential referral sources. Generally, courts have taken a broad interpretation of the scope of the federal Anti-Kickback 
Statute,  holding  that  the  statute  may  be  violated  if  merely  one  purpose  of  a  payment  arrangement  is  to  induce  future 
referrals. 

The HHS Office of Inspector General, or OIG, has issued Special Fraud Alerts on arrangements for the provision 
of clinical laboratory services and relationships between, among others, laboratories and referral sources. The Fraud Alerts 
set forth a number of practices allegedly engaged in by some clinical laboratories and healthcare providers that raise issues 
under the federal fraud and abuse laws, including the federal Anti-Kickback Statute. The OIG emphasized in the Special 
Fraud  Alerts  that  when  one  purpose  of  such  arrangements  is  to  induce  referrals  of  government  program-reimbursed 
laboratory testing, both the clinical laboratory and the healthcare provider (e.g., physician) may be liable under the federal 
Anti-Kickback Statute, and may be subject to civil and/or criminal prosecution and exclusion from participation in the 
Medicare and Medicaid programs. 

Recognizing that the federal Anti-Kickback Statute is broad and may technically prohibit many innocuous or 
beneficial arrangements within the healthcare industry, HHS has issued a series of regulatory “safe harbors” for certain 
payment arrangements which provide confidence to healthcare providers and other parties that they will not be prosecuted 
under the federal Anti-Kickback Statute if they can demonstrate compliance with each element of the safe harbor. Although 
full compliance with these provisions ensures against prosecution under the federal Anti-Kickback Statute, the failure of 
a  transaction  or  arrangement  to  fit  within  a  specific  safe  harbor  does  not  necessarily  mean  that  the  transaction  or 
arrangement is illegal or that prosecution under the federal Anti-Kickback Statute will be pursued. 

While we believe that we are in compliance with the federal Anti-Kickback Statute and similar fraud and abuse 
laws, there can be no assurance that our relationships with physicians, hospitals and other customers or vendors will not 
be subject to scrutiny or will survive regulatory challenge under such laws. If imposed for any reason, sanctions under the 
federal Anti-Kickback Statute or any similar state statute could have a negative effect on our business. 

Because we operate a laboratory facility located in California and licensed by California’s DHS, California law 
is  applicable  to  our  business  arrangements.  California’s  state  anti-kickback  statutes,  Business  and  Professions  Code 
Section 650 (which applies to all categories of payors) and Insurance Code Section 754, and its Medi-Cal anti-kickback 
statute,  Welfare  and  Institutions  Code  Section  14107.2,  are  analogous  to,  and  have  been  interpreted  by  the  California 
Attorney  General  and  California  courts  in  substantially  the  same  way  as  the  federal  government  and  the  courts  have 
interpreted, the federal Anti-Kickback Statute. A violation of Section 650 is punishable by up to one year of imprisonment, 
a fine up to $50,000, or both imprisonment and a fine. A violation of Section 14107.2 is punishable by imprisonment and 
fines  of  up  to  $10,000.  The  California  Insurance  Code  includes  similar  prohibitions  against  any  consideration  for  the 
referral or procurement of patients if a claim is submitted to a commercial insurer, CA Ins. Code § 750, which is punishable 
by criminal penalties mirroring those that apply to violations of Business and Professions Code Section 650. 

Because  our  San  Carlos  laboratory  holds  a  New  York  CLEP  permit,  we  must  comply  with  New  York  state 
laboratory statutes and regulations, which include anti-kickback provisions, Public Health Law Section 587, and Medicaid 
anti-kickback provisions, 18 NYCRR Section 515.2, related to laboratory services. The New York DOH may suspend, 
limit, revoke or annul the New York laboratory permit or otherwise discipline the permit holder for a violation. 

24 

Because we operate a laboratory facility located in Texas, our business arrangements are subject to certain Texas 
laws.  Texas’s primary anti-kickback statute, Texas Patient Solicitation Act (Tex. Occ. Code § 102.001) (which applies to 
all  categories  of  payors),  provides  for  an  exception  to  any  business  arrangement  that  complies  with  the  federal  Anti-
Kickback Statute or any regulation adopted under that law. Even if a business arrangement is compliant with the Texas 
Patient Solicitation Act, disclosure to the patient is required. A violation of Section 102.001 or 102.006 is punishable by 
civil penalties (up to $10,000 per violation). The Texas Medicaid anti-kickback laws, 1 TAC 371.1669, cross-references 
the Texas Patient Solicitation Act and include other prohibited self-referrals that are grounds for enforcement and sanctions. 
The Texas Insurance Code includes criminal penalties for similar prohibitions related to improper referral or procurement 
of patients if a claim is submitted to a commercial insurer. 

In addition to the requirements that are discussed above, there are other healthcare  fraud and abuse laws that 
could have an impact on our business. The federal False Claims Act prohibits a person from knowingly submitting or 
causing  to  be  submitted  false  claims  or  making  a  false  record  or  statement  in  order  to  secure  payment  by  the  federal 
government. Actions which violate another law in this section may also result in liability under the Federal False Claims 
Act as a result of the submission of claims pursuant to a prohibited arrangement. In addition to actions initiated by the 
government itself, the statute authorizes actions to be brought on behalf of the federal government by a private party having 
knowledge of the alleged fraud sometimes referred to as a “whistleblower”. 

Because the complaints are initially filed under seal, the action may be pending for some time before the defendant 
is even aware of the action. If the government is ultimately successful in obtaining redress in the matter or if the private 
party plaintiff succeeds in obtaining redress without the government’s involvement, then the private party plaintiff will 
receive a percentage of the recovery. Violation of the federal False Claims Act may result in fines of up to three times the 
actual  damages  sustained  by  the  government,  plus  mandatory  civil  penalties  of  up  to  approximately  $22,363  for  each 
separate false claim, imprisonment or both, and possible exclusion from Medicare or Medicaid. The penalties will continue 
to be adjusted, increasing each year to reflect changes in the inflation rate, pursuant to the 2015 Bipartisan Budget Act. 

In 2018, the Eliminating Kickbacks in Recovery Act of 2018, or EKRA, was passed as part of the Substance Use-
Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (referred to as the 
SUPPORT Act). Similar to the federal Anti-Kickback statute, EKRA 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 is not limited to government health care benefit programs, so the prohibitions extend 
to services covered by commercial health plans. 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.  As  currently drafted, EKRA  potentially  expands  the universe  of  arrangements that 
could be subject to government enforcement under federal fraud and abuse laws. Violation of EKRA carries potential 
penalties of up to $200,000 in fines and imprisonment of up to 10 years for each occurrence. 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.  We  cannot  assure  you  that  our  relationships  with  physicians,  sales 
representatives, hospitals or customers will not be subject to scrutiny or will survive regulatory challenge under EKRA. If 
imposed for any reason, sanctions under EKRA could have a negative effect on our business. 

We  are  also  subject  to  a  federal  law  directed  at  “self-referrals,”  commonly  known  as  the  Stark  Law,  which 
prohibits, with certain exceptions, payments made by a laboratory to a physician in exchange for the referral of clinical 
laboratory services, or presenting or causing to be presented claims to Medicare and Medicaid for laboratory tests referred 
by physicians who personally, or through a family member, have an investment interest in, or a compensation arrangement 
with, the clinical laboratory performing the tests. A person who engages in a scheme to circumvent the Stark Law’s referral 
prohibition may be fined up to $100,000 for each such arrangement or scheme. In addition, any person who presents or 
causes to be presented a claim to the Medicare or Medicaid programs in violation of the Stark Law is subject to civil 
monetary penalties of up to $15,000 per claim submission, an assessment of up to three times the amount claimed, and 
possible exclusion from participation in federal governmental payer programs. Claims submitted in violation of the Stark 

25 

Law may not be paid by Medicare or Medicaid, and any person collecting any amounts with respect to any such prohibited 
claim is obligated to refund such amounts. Actions which violate the Stark Law may be bootstrapped to involve liability 
under the Federal False Claims Act. 

Many states, including California, also have state “physician self-referral” prohibitions and other laws that are 
not limited to Medicare and Medicaid referrals, with which we must comply. We are subject to California’s Physician 
Ownership and Referral Act, or PORA, which generally prohibits us from billing a patient or any governmental or private 
payer for any laboratory services when the physician ordering the service, or any member of such physician’s immediate 
family, has a “financial interest” with us, unless the arrangement meets an exception (CA Business and Professions Code 
Section 650.02). The term “financial interest” is defined broadly and includes any type of ownership interest, debt, loan, 
lease, compensation, remuneration, discount, rebate, refund, etc. between the ordering physician and the entity receiving 
the referral. The exceptions to PORA track certain of the Stark Law exceptions, including an exception for personal service 
arrangements  and  for  ownership  of  publicly  traded  entities.  A  violation  of  PORA  is  punishable  by  civil  and  criminal 
penalties (civil penalties and criminal fines vary depending on the nature of the violation, but may reach up to $15,000 per 
violation). 

Other states may have self-referral restrictions with which we have to comply that differ from those imposed by 

federal and California law. 

We are also subject to applicable 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. California has an anti-
markup statute with which we must comply, 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)  (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. A violation of this provision can lead to imprisonment and/or a fine of up to $10,000. Other states have similar anti-
markup prohibitions with which we must comply. 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 (CA Business and Professions Code Section 655.7). 

While we have attempted to comply with the federal, Texas, California and New York fraud and abuse laws and 
similar laws of other states and non-U.S. jurisdictions, it is possible that some of our arrangements could be subject to 
regulatory scrutiny at some point in the future, and we cannot provide assurance that we will be found to be in compliance 
with these laws following any such regulatory review. 

Further,  in  addition  to  the  privacy  and  security  regulations  stated  above,  HIPAA  created  two  federal  crimes: 
healthcare fraud and false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and 
willfully executing a scheme to defraud any healthcare benefit program, including private payers. A violation of this statute 
is a felony and may result in fines, imprisonment or exclusion from government sponsored programs. The false statements 
statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially 
false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or 
services. A violation of this statute is a felony and may result in fines or imprisonment. 

Finally, federal law prohibits any entity from offering or transferring to a Medicare or Medicaid beneficiary any 
remuneration that the entity knows or should know is likely to influence the beneficiary’s selection of a particular provider, 
practitioner  or  supplier  of  Medicare  or  Medicaid  payable  items  or  services,  including  waivers  of  copayments  and 
deductible amounts (or any part thereof), if any apply, and transfers of items or services for free or for other than fair 

26 

market value. Entities found in violation may be liable for civil monetary penalties of up to $100,000 for each wrongful 
act. Although we believe that our business activities and practices, including our sales and marketing practices, are in 
material compliance with all applicable federal and state laws and regulations, relevant regulatory authorities may disagree, 
and violation of these laws or our exclusion from such programs as Medicare, Medicaid and other federal health care 
programs as a result of a violation of such laws could have a material adverse effect on our business, results of operations, 
financial condition and cash flows.  

Human Capital Management 

Consistent with, and to support, the rapid growth in our business, we have significantly grown our employee 
headcount  in  recent years. As  of December  31,  2020, we had 1,815  full-time  employees, representing  growth of  43% 
during 2020. We also engage consultants and temporary employees. We have not been subject to labor action or union 
activities, and our management considers its relationships with employees to be good. 

Our  compensation  programs  are  designed  to  attract  and  reward  talented  individuals  who  possess  the  skills 
necessary to support our business objectives, assist in the achievement of our strategic goals and ultimately create long-
term value for our stockholders. In addition to base pay, our compensation and benefits programs, which can vary by 
region,  can  include  annual  bonuses,  stock-based  compensation  awards,  a  401(k)  plan  with  employee  matching 
opportunities, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, parental 
leave, and employee assistance programs. We work to ensure pay equity by annually assessing our compensation practices 
and working with external compensation consultants to design and benchmark our programs. 

We  operate  in  an  industry  in  which  competition  for  highly  qualified  personnel  is  intense.  In  addition  to  our 
compensation programs, we are highly focused on talent acquisition, retention and development. We conduct an annual 
employee  engagement  survey,  the  results  of  which  inform  internal  company  and  management  goals  to  help  ensure 
impactful and meaningful actions in response to feedback received. Our annual employee evaluation process helps us to 
support developing employees as well as identify and cultivate high performers, and we have various initiatives underway 
to further develop leaders and managers. 

Diversity is one of our company core values, and we believe in creating an inclusive and equitable environment 
that  represents  a  broad  spectrum  of  backgrounds  and  cultures.  We  have  two  employee  resource  groups,  or  ERGs, 
committed to furthering our efforts in this area. Women of Natera and our Diversity & Inclusion Group both serve as 
resources  to  the  organization  in  fostering  a  culture  of  inclusion  and  diversity  by  providing  a  platform  of  networking, 
ongoing learning and exchange to support professional development and promote workplace equality and diversity.  

In response to the COVID-19 pandemic, we implemented significant changes that we determined were in the best 
interest of our employees and which comply with government orders in all the states and countries where we operate. In 
an  effort  to  keep  our  employees  safe  and  to  maintain  operations  during  the  COVID-19  pandemic,  we  implemented  a 
number of health-related measures, including implementing a general work from home policy and restricting on-site access 
to essential employees such as laboratory personnel, increasing hygiene, cleaning and sanitizing procedures at our office 
and laboratory facilities, requiring face masks while on company premises, and implementing temperature checks and 
COVID-19 testing requirements in order to enter company facilities.

ITEM 1A. 

RISK FACTORS  

Investing  in  our  common  stock  involves  a  high  degree  of  risk.  You  should  consider  carefully  the  risks  and 
uncertainties  described  below,  together  with  all  of  the  other  information  in  this  report,  including  the  section  titled 
“Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations”  and  our  consolidated 
financial statements and related notes, before investing in our common stock. The risks and uncertainties described below 
are not the only ones we face. If any of the following risks actually occurs, our business, financial condition, results of 
operations and prospects could be materially and adversely affected. In that event, the price of our common stock could 
decline and you could lose part or all of your investment. 

Risks Related to Our Business and Industry 

We face risks related to health epidemics, including the current COVID-19 pandemic, which could have a material 
adverse effect on our business and results of operations. 

Our business operations have been and continue to be adversely affected by the ongoing pandemic of respiratory 
illness  caused  by  a  novel  strain  of  coronavirus,  SARS-CoV-2,  causing  the  Coronavirus  Disease  2019,  also  known  as 
COVID-19.  Global  health  concerns  relating  to  the  COVID-19  pandemic  have  been  weighing  on  the  macroeconomic 
environment, and the pandemic has significantly increased economic volatility and uncertainty. 

The pandemic has resulted in government authorities implementing numerous measures to try to contain the virus, 
such  as  travel  bans  and  restrictions,  quarantines,  shelter-in-place  or  stay-at-home  orders,  and  business  shutdowns.  For 

29 

 
 
 
 
 
example, our personnel located at our offices and laboratories in Texas, California and elsewhere in the United States and 
in other countries have been subject to various shelter-in-place or stay-at-home orders from state and local governments 
for  the  past  several  months.  These  measures  have  adversely  impacted  and  may  further  impact  our  employees  and 
operations,  and  the  operations  of  our  customers,  suppliers and  business partners,  and  may  negatively  impact  spending 
patterns,  payment  cycles  and  insurance  coverage  levels.  These  measures  have  adversely  affected  and  are  expected  to 
continue to adversely affect demand for our tests. Many of our customers, including hospitals and clinics, have suspended 
non-emergency appointments and services, which resulted in a significant decrease in our test volume. In addition, because 
we rely heavily on our direct sales force to sell our tests, we expect our sales cycle, particularly for new customers, will 
continue to be significantly impacted. Travel bans, restrictions and border closures have also impacted our ability to ship 
test  kits  to  and  receive  samples  from  our  customers.  In  addition,  certain  aspects  of  our  business,  such  as  laboratory 
processes, cannot be conducted remotely. These measures by government authorities may continue to remain in place or 
be implemented to varying degrees from time to time for the foreseeable future, and they are likely to continue to adversely 
affect our test volume, sales activities and overall operations for an indefinite period of time. 

In addition, it may be more difficult for us to develop new products for commercial release, as we expect it will 
be more difficult to complete our research and development efforts and commence and complete clinical trials while the 
pandemic is ongoing. It is also possible that demand for products that we may pursue could be materially and adversely 
affected as a result of COVID-19, disruptions to our or our customers’ operations, and any related economic impact. 

The spread of COVID-19 has caused us to modify our business practices (including employee travel, mandating 
that  all  non-essential  personnel  work  from  home,  temporary  closures  of  our  offices,  and  cancellation  of  physical 
participation in sales activities, meetings, events and conferences) and incur additional operating costs, and we may take 
further actions as may be required by government authorities or that we determine are in the best interests of our employees, 
customers and business partners. Such actions could also impact our ability to fully integrate businesses we may acquire 
in the future. There is no certainty that such actions will be sufficient to mitigate the risks posed by the virus or otherwise 
be satisfactory to government authorities. If significant portions of our workforce, and particularly our laboratory staff, are 
unable to work effectively, including due to illness, quarantines, social distancing, government actions or other restrictions 
in connection with the COVID-19 pandemic, our operations will be impacted. 

The extent to which the COVID-19 pandemic impacts our business, results of operations and financial condition 
will depend on future developments, which remain highly uncertain and cannot be predicted, including, but not limited to, 
the continued duration and spread of the pandemic, its severity, the actions to contain the virus or address its impact, and 
when and to what extent normal economic and operating activities can resume. The COVID-19 pandemic could limit the 
ability of our customers, suppliers and business partners to perform under their contracts with us, including third-party 
payers’ ability to make timely payments to us during and following the pandemic. We may also experience a shortage of 
laboratory supplies and reagents or a suspension of services from other laboratories or third parties. We have also become 
increasingly dependent on growing and maintaining a network of mobile phlebotomy specialists who can provide testing 
capabilities, as many consumers are unable to visit clinics, hospitals or other testing facilities as a result of the pandemic. 
Even after the pandemic has subsided, we may continue to experience an adverse impact to our business as a result of its 
global economic impact, including any recession that has occurred or may occur in the future. 

Specifically, difficult macroeconomic conditions, such as decreases in per capita income and level of disposable 
income  and  related  health  insurance  coverage,  increased  and  prolonged  unemployment  or  a  decline  in  consumer 
confidence as a result of the pandemic, as well as limited or significantly reduced points of access of our products, could 
have a material adverse effect on the demand for some of our products, such as our products targeted for the IVF market. 
Decreased demand for our tests, particularly in the United States, could negatively affect our overall financial performance. 
A significant portion of our revenue is concentrated in the United States, where the impact of COVID-19 continues to be 
significant, and the potential decrease in demand for our tests could have a disproportionately negative impact on our 
business and financial results. 

In addition, the stock market has been unusually volatile during the COVID-19 pandemic and such volatility may 
continue,  and  financial  markets  generally  have  experienced  periods  of  significant  volatility.  Our  stock  price  has  also 
experienced volatility during this time, including occasional significant declines, and such declines may repeat or continue 
for the foreseeable future. 

30 

We do not yet know the full extent and duration of the impact of the COVID-19 pandemic on the United States 
or global economies as a whole, nor the resulting ultimate impact on our operations, and there are no comparable recent 
events which may provide guidance in this respect. However, the effects have impacted our business and operations, we 
expect that they will continue to have a material adverse impact on our business and results of operations. 

We have derived the significant majority of our revenues from Panorama and Horizon, and if our efforts to further 
increase the use and adoption of Panorama and Horizon or to develop new products and services in the future do not 
succeed, our business will be harmed. 

Historically,  including  for  the  year  ended  December 31,  2020,  the  significant  majority  of  our  revenues  were 
derived from sales of our Panorama NIPT and our Horizon carrier screening, or HCS, test, and we expect this to continue 
to  be  the  case.  With  respect  to  Panorama  in  particular,  continued  and  additional  market  demand  for  Panorama,  and 
reimbursement for the average-risk population and for microdeletions, are key elements to our future success. The market 
demand for NIPTs and carrier screening tests continue to evolve. We cannot guarantee that physicians will recommend 
and order Panorama or Horizon, and our laboratory distribution partners and licensees may not actively or effectively 
market Panorama or Horizon. 

Our ability to increase sales and establish significant levels of adoption and reimbursement for Panorama and 
Horizon is uncertain, and it may be challenging for us to achieve profitability for many reasons, including, among others: 

• 

• 

• 

• 

• 

• 

the market for our tests may not grow as we expect; in particular, NIPTs may not gain acceptance for use in 
the average-risk pregnancy population or as a screen for microdeletions, which would limit the market for 
Panorama, and we may fail to compete successfully in this market, whatever size; 

if we are unable to demonstrate that our tests are superior to competing tests, laboratories, clinics, clinicians, 
physicians, payers and patients may not adopt the use of Panorama, Horizon or our other tests on a broad 
basis, and may not be willing to pay the price premium over competing tests that we have, to date, been able 
to achieve; 

third-party  payers,  such  as  commercial  insurance  companies  and  government  insurance  programs,  may 
decide  not  to  reimburse  for  Panorama  or  Horizon,  may  not  reimburse  for  uses  of  Panorama  for  the 
average-risk pregnancy population or for the screening of microdeletions, or may set the amounts of any 
reimbursements at prices that do not allow us to cover our expenses; in fact, many third-party payers currently 
have negative coverage determinations or otherwise do not reimburse for microdeletions screening and we 
expect low reimbursement rates for microdeletions screening to continue, at least in the near term; also, most 
state Medicaid programs currently either reimburse at low rates or do not reimburse for our tests; 

third-party payers have increasingly required that prior authorization be obtained prior to conducting genetic 
testing as a condition to reimbursing for it, which has reduced and/or delayed the reimbursement amounts 
we receive for Panorama, Horizon and our other tests, which has impacted our results of operations since the 
fourth quarter of 2017, when these requirements began to take effect; 

the results of our SMART Study evaluating the performance of Panorama may fail to convince laboratories, 
clinics, clinicians, physicians or patients of the benefits of utilizing Panorama in average-risk pregnancies or 
for microdeletions and may not increase reimbursement for Panorama; 

the results of our clinical trials and any additional clinical and economic utility data that we may develop, 
present and publish in the future or that comes from the commercial use of our tests may be inconsistent with 
our existing data, including the data from our SMART Study, and may raise questions about the performance 
of our tests, or may fail to convince laboratories, clinics, clinicians, physicians, payers or patients of the value 
of our tests; we may experience supply constraints, including those due to the failure of our key suppliers to 
provide required sequencers and reagents in sufficient amounts or of adequate quality or disputes with our 
key  suppliers,  including  those  with  respect  to  the  required  sequencers  and  reagents  from  our  supplier, 
Illumina, Inc., or Illumina, who is also one of our main NIPT competitors through its subsidiary, Verinata 

31 

Health Inc., or Verinata, and with whom we have historically been involved in patent proceedings as further 
described in “Note 8—Commitments and Contingencies—Legal Proceedings” in the Notes to Consolidated 
Financial Statements; 

•  we  may  experience  increased  cost  of  product  revenues,  and  cost  of  licensing  and  other  revenues,  as  a 

percentage of total revenues, as has been the case in previous fiscal periods; 

• 

• 

the U.S. Food and Drug Administration, or the FDA, or other U.S. or foreign regulatory or legislative bodies 
may adopt new regulations or policies, or take other actions that impose significant restrictions on our ability 
to market and sell Panorama, Horizon or our other tests, including requiring FDA clearance or approval for 
the sale of Panorama or Horizon or of the sequencers, reagents, kits and other consumable products that we 
purchase from third parties in order to perform our testing; 

our laboratory partners may choose to develop their own tests that are competitive with ours or offer tests 
provided by our competitors due to pricing or other reasons as has happened in the past, or otherwise fail to 
effectively  market  our  tests;  and  competitors  may  develop  and  commercialize  more  effective  and/or  less 
expensive tests that deliver comparable results as our tests; 

•  we may fail to adequately protect or enforce our intellectual property relating to our tests, leading to increased 
competition;  or  other  parties  may  claim  that  the  practice  of  our  technology  by  us  or  our  licensees  and 
collaborators  infringes  such  other  party’s  intellectual  property  rights,  as  certain  of  our  competitors  have 
claimed in lawsuits filed against us, as discussed further in “Note 8—Commitments and Contingencies—
Legal Proceedings” in the Notes to Consolidated Financial Statements; if we are required to pay license fees 
in order to license third-party intellectual property rights due to actual or alleged infringement based on our 
running our tests, we may experience increased costs in running our tests, and we may be unable to pass such 
costs on to our customers; 

•  we may be unable to dedicate adequate resources to the maintenance and further technological advancement 
of Panorama and Horizon that are necessary for such tests to be competitive in the marketplace because of 
the demands placed on our research and development and product teams with respect to our continuously 
expanding portfolio of products and programs, in particular our efforts and focus on developing our oncology 
and organ health businesses; 

• 

in  the  event  that  it  is  in  our  commercial  or  financial  interest  or  we  are  forced  to  transition  sequencing 
platforms for Panorama, we may be unable to do so in a commercially sustainable way and that could survive 
claims of infringement of intellectual property rights of Illumina and other competitors, in a timely manner 
or at all; and 

•  we may not be successful in commercializing our cloud-based distribution model. 

If the market for Panorama or Horizon, or our market share for either test, fail to grow or grow more slowly than 

expected, our business, operating results and financial condition will be harmed. 

We  have  incurred  net  losses  since  our  inception  and  we  anticipate  that  we  will  continue  to  incur  losses  for  the 
foreseeable future, which could harm our future business prospects. 

We have incurred net losses each year since our inception in 2003. To date, we have financed our operations 
primarily through private placements of preferred stock, convertible debt and other debt instruments, our initial public 
offering and our registered public equity offerings. Our net loss for the years ended December 31, 2020, 2019 and 2018 
was $229.7 million, $124.8 million and $128.2 million, respectively. As of December 31, 2020, we had an accumulated 
deficit of $929.3 million. Such losses may continue to increase in the future as we continue to devote a substantial portion 
of our resources to efforts to increase the adoption of, and reimbursement for, Panorama, Horizon and our other products, 
improve these products, and research and develop and commercialize new products, which increasingly are in industries 
that are relatively new to us, such as oncology and organ health. 

32 

In addition, the rate of growth in our revenues has fluctuated in the past, and may continue to do so in future 
periods. In particular, such rate of growth may be negative, low or flat, including if the rate of growth of our test volumes 
slows. A significant element of our business strategy is to maintain increased in-network coverage with third-party payers; 
however, the negotiated fees under our contracts with third-party payers are typically lower than the list price of our tests, 
and in some cases the third-party payers that we contract with have negative coverage determinations for some of our 
offerings, in particular Panorama for microdeletions screening. Therefore, being in-network with third-party payers has 
had, and may continue to have, an adverse impact on our revenues especially if we are unable to increase the adoption of, 
and  obtain  favorable  coverage  determinations  for  reimbursement  for,  our  products.  Furthermore,  a  CPT  code  for 
microdeletions went into effect beginning in January 2017. We have experienced low average reimbursement rates for 
microdeletions  testing  under  this  code,  and  we  expect  that  this  code  will  continue  to  cause  our  microdeletions 
reimbursement to remain low, at least in the near term, either due to reduced reimbursement, or third-party payers declining 
to  reimburse, under  the microdeletions  code,  which has had  and will  likely  continue  to  have  an  adverse  effect  on our 
revenues. In addition, a CPT code for expanded carrier screening went into effect beginning in January 2019, and has had, 
and may continue to have, an adverse effect on our reimbursement rates for our broader Horizon carrier screening panel, 
for which we previously primarily received reimbursement on a per condition basis, as those tests may be reimbursed as a 
combined single panel instead of as multiple individual tests. 

As further discussed in the risk factor entitled “—We may not be successful in commercializing our cloud-based 
distribution model,” our results of operations may be adversely affected if we do not sell a sufficient volume of tests under 
our cloud-based distribution model to offset the lower revenues per test performed under that model. Our ability to forecast 
our  future  operating  results,  including  revenues,  cash  flows  and  profitability,  is  limited  and  subject  to  a  number  of 
uncertainties. We have also encountered and will continue to encounter risks and uncertainties frequently experienced by 
growing companies in the life sciences and technology industry, such as those described in this report. If our assumptions 
regarding these risks and uncertainties are incorrect or these risks and uncertainties change, or if we do not address these 
risks successfully, our operating and financial results may differ materially from our expectations, and our business may 
suffer. 

Uncertainty  in  the  development  and  commercialization  of  our  enhanced  or  new  tests  or  services  could  materially 
adversely affect our business, financial condition and results of operations. 

Our success will depend in part on our ability to effectively introduce enhanced or new offerings. The focus of 
our research and development efforts has expanded beyond reproductive health products, as we are now also applying our 
expertise in processing and analyzing cell-free DNA in the fields of oncology and organ health. In recent years we have 
developed and/or launched several new products or enhanced versions of existing products, including our first offerings 
in oncology and in organ health, and we expect to continue our efforts in all of these areas. The development and launch 
of enhanced or new tests requires the completion of certain clinical development and commercialization activities that are 
complex, costly, time-intensive and uncertain, and requires us to accurately anticipate patients’, clinicians’, payers’ and 
other counterparties’ attitudes and needs as well as emerging technology and industry trends. This process is conducted in 
various stages, and each stage presents the risk that we will not achieve our goals. 

We  may  not  be  successful  in  our  current  or  future  efforts  to  develop  and  commercialize  cell-free  DNA  tests 
outside  of  the  reproductive  health  space.  Moreover,  we  have  limited  experience  forecasting  our  future  financial 
performance from our new products in these industries that are newer to us, and our actual results may fall below our 
financial guidance or other projections, or the expectations of analysts or investors, which could cause the price of our 
common stock to decline. We may experience research and development, regulatory, marketing and other difficulties that 
could  delay  or  prevent  our  introduction  of  enhanced  or  new  tests  and  result  in  increased  costs  and  the  diversion  of 
management’s  attention  and  resources  from  other  business  matters,  such  as  from  our  Panorama  and  Horizon  product 
offerings, which currently represent the significant majority of our revenues. For example, any tests that we may enhance 
or develop may not prove to be clinically effective in clinical trials or commercially, or may not ultimately meet our desired 
target product profile, be offered at acceptable cost and with the sensitivity, specificity and other test performance metrics 
necessary to address the relevant clinical need or commercial opportunity; our test performance in commercial experience 
may be inconsistent with our validation or other clinical data; we may not be successful in achieving market awareness 
and demand, whether through our own sales and marketing operations or through collaborative arrangements; healthcare 
providers may not order or use, or third-party payers may not reimburse for, any tests that we may enhance or develop; or 

33 

we may otherwise have to abandon a test or service in which we have invested substantial resources. In particular, we are 
subject  to  the  risk  that  the  biological  characteristics  of  the  genetic  mutations  we  seek  to  target,  and  upon  which  our 
technologies rely, are uncertain and difficult to predict. For example, in our efforts to detect and analyze circulating tumor 
DNA in plasma for MRD assessment and recurrence surveillance, our success depends on tumors shedding mutant DNA 
into the bloodstream in sufficient quantities such that our technology can detect such mutations. As further discussed in 
the risk factor entitled “If our products do not perform as expected, our operating results, reputation and business will 
suffer,”  we  may  also  experience  unforeseen  difficulties  when  implementing  updates  to  our  processes,  as  we  have 
occasionally experienced with Panorama and with Horizon. 

We cannot assure you that we can successfully complete the clinical development of any new or enhanced product, 
or that we can establish or maintain the collaborative relationships that may be essential to our clinical development and 
commercialization efforts. Clinical development requires large numbers of patient specimens and, for certain products, 
may require large, prospective, and controlled clinical trials. We may not be able to enroll patients or collect a sufficient 
number of appropriate specimens in a timely manner; or we may experience delays during clinical development due to 
slower than anticipated enrollment, which we experienced in the past with our SNP-based Microdeletions and Aneuploidy 
RegisTry, or SMART, Study, or due to changes in study design or other unforeseen circumstances, such as our decisions 
in the past to expand our SMART Study; or we may be unable to afford or manage the large-sized clinical trials that some 
of our planned future products may require. 

The  publication  of  clinical  data  in  peer-reviewed  journals  is  a  crucial  step  in  commercializing  and  obtaining 
reimbursement for tests such as ours, and our inability to control when, if ever, results are published may delay or limit 
our ability to derive sufficient revenues from any test that is the subject of a study. Peer-reviewed publications regarding 
our tests may be limited by many factors, including delays in the completion of, poor design of, or lack of compelling data 
from, clinical studies, as well as delays in the review, acceptance and publication process. If our tests or the technology 
underlying our current or future tests do not receive sufficient favorable exposure in peer-reviewed publications, the rate 
of clinician adoption of our tests and positive reimbursement coverage determinations for our tests could be negatively 
affected. Further, the data collected from any studies we complete in the future may not be favorable or consistent with 
our existing data or may not be statistically significant or compelling to the medical community or to third-party payers 
seeking such data for purposes of determining coverage for our tests. For example, we recently presented certain results 
of our SMART Study, and expect to publish our results in 2021. The objective of the SMART Study was to evaluate the 
performance of SNP-based NIPT for 22q11.2 deletion syndrome by tracking birth outcomes in the general population 
among over 18,000 women who presented clinically and elected Panorama microdeletion and aneuploidy screening as part 
of  their  routine  care.  We  cannot  assure  you  that  the  results  of  our  SMART  Study  will  convince  laboratories,  clinics, 
clinicians, physicians or patients of the benefits of utilizing Panorama in average-risk pregnancies or for microdeletions. 
We  also  cannot  be  certain  whether,  or  to  what  extent,  the  SMART  Study  may  impact  insurance  coverage  and 
reimbursement for Panorama in the average-risk population or for microdeletions.  

In addition, as further described in the risk factor entitled “—If the FDA were to begin actively regulating our 
tests, we could incur substantial costs and delays associated with trying to obtain premarket clearance or approval and 
incur costs associated with complying with post-market controls,” development of the data necessary to obtain regulatory 
clearance and approval of a test is time-consuming and carries with it the risk of not yielding the desired results. The 
performance  achieved  in  published  studies  may  not  be  repeated  in  later  studies  that  may  be  required  to  obtain  FDA 
premarket  clearance  or  approval  or  regulatory  approvals  in  foreign  jurisdictions.  Limited  results  from  earlier-stage 
verification studies may not predict results from studies in larger numbers of subjects drawn from more diverse populations 
over longer periods of time. Unfavorable results from ongoing preclinical and clinical studies may delay, limit or prevent 
regulatory approvals or clearances or commercialization of our product candidates, or could result in delays, modifications 
or abandonment of ongoing analytical or future clinical studies, or abandonment of a product development program, any 
of which could have a material adverse effect on our business, operating results or financial condition. 

These  and  other  factors  beyond  our  control  could  result  in  delays  or  other  difficulties  in  the  research  and 
development, approval, production, launch, ongoing commercialization or distribution of enhanced or new tests and could 
adversely affect our competitive position and results of operations. 

34 

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

Our quarterly results of operations, including our revenues, gross margin, net loss and cash flows, may vary from 
period to period as a result of a variety of factors, many of which are outside of our control, including those listed elsewhere 
in this “Risk Factors” section, and as a result, period-to-period comparisons of our operating results may not be meaningful. 
Our quarterly results should not be relied upon as an indication of future performance. In addition, to the extent that we 
continue to spend considerably on our internal sales and marketing and research and development efforts, we expect to 
incur costs in advance of achieving the anticipated benefits of such efforts. Fluctuations in quarterly results and key metrics 
may cause our results to fall below our financial guidance or other projections or goals, or the expectations of analysts or 
investors,  which  could  adversely  affect  the  price  of  our  common  stock.  We  also  face  competitive  pricing  and 
reimbursement pressures, and we may not be able to maintain our premium pricing in the future, which would adversely 
affect our operating results. 

Competition in our industry is intense; if we are unable to compete successfully with respect to our current or future 
products or services, we may be unable to increase or sustain our revenues or achieve profitability. 

We  compete  primarily  in  the  molecular  testing  field,  which  is  characterized  by  rapid  technological  changes, 
frequent new product introductions, reimbursement challenges, emerging competition, intellectual property disputes and 
litigation,  price  competition,  aggressive  marketing  practices,  evolving  industry  standards  and  changing  customer 
preferences. Our principal competition in women’s health comes from existing testing methods, technologies and products 
that are used by OB/GYNs, MFM specialists or IVF centers. These include other NIPTs and carrier screening tests offered 
by  our  competitors,  as  well  as  established,  traditional  first-line  prenatal  screening  methods,  such  as  serum  protein 
measurement,  where  doctors  measure  certain  hormones  in  the  blood,  and  invasive  prenatal  diagnostic  tests  like 
amniocentesis, which have been used for many years and are therefore difficult to displace or supplement. In addition, 
new testing methods may be developed which may displace or be preferred over NIPTs, such as whole genome sequencing 
or single cell analysis. We are relatively new to the fields of oncology and organ health, and face competition in these 
business areas from other companies, many of which are larger, more established and have more experience and more 
resources  than  we  do.  Some  companies  in  the  ctDNA-based  liquid  biopsy  field  are  expanding  their  research  and 
development efforts to include tracking more tumor-specific variants and/or other biomarkers in addition to ctDNA, on 
the basis that these analyses may collectively result in improved sensitivity and earlier detection than currently available 
tests, such as Signatera. We cannot assure you that research, discoveries or other advancements by other companies will 
not render our existing or potential products and services uneconomical or result in products and services that are superior 
or otherwise preferable to our current or future products and services. 

We compete with numerous companies in the genetic diagnostics space. Our primary competitors in NIPT include 
Sequenom, which was acquired by LabCorp; Illumina, through its subsidiary Verinata; Ariosa, a subsidiary of Roche; 
Myriad  Genetics, Inc.,  which  has  acquired  Counsyl,  Inc;  Invitae  Corp.;  Bio-Reference,  a  business  unit  of  OPKO 
Health, Inc.; Quest; Premaitha Health PLC; BGI; Progenity, Inc., or Progenity; NxGen; BillionToOne Inc.; PerkinElmer 
Inc.; and Mount Sinai Genomics, Inc. d/b/a Sema4. All of our main NIPT competitors in the United States are owned or 
controlled by companies much larger than ours and with much greater resources for sales, marketing and research and 
development efforts. Our primary competitors in carrier screening include LabCorp; Myriad Genetics, Inc.; Sema4; Invitae 
Corp.;  Progenity;  Quest;  Recombine Inc.;  GeneDx, Inc.,  a  subsidiary  of  Bio-Reference;  and  GenPath  Diagnostics,  a 
business  unit  of  Bio-Reference.  In  the  field  of  ctDNA-based  MRD  assessment  and  recurrence  surveillance,  we  face 
competition from various companies that offer or seek to offer competing solutions, such as Roche Diagnostics, a division 
of Roche; Guardant Health, Inc., Adaptive Biotechnologies, Personal Genome Diagnostics, Inc.; Exact Sciences Corp.; 
Inivata, Inc.; C2i Genomics, Inc.; and ArcherDX, Inc., or ArcherDX, which has been acquired by Invitae Corp., one of 
our primary competitors in both NIPT and carrier screening. In the field of organ health, our primary competitors include 
CareDx and Eurofins Viracor, Inc. We expect that competition in these spaces will continue to increase. 

Some of our competitors’ products and services are sold at a lower price than ours, which could cause sales of 
our tests and services to decline or force us to reduce our prices. Our current and future competitors could have greater 
technological, financial, reputational and market access advantages than us, and we may not be able to compete effectively 
against  them.  Increased  competition  is  likely  to  result  in  pricing  pressures,  which  could  harm  our  revenues,  operating 
income or market share. We are increasingly subject to litigation with our competitors; for example, as disclosed elsewhere 
in these risk factors, we are or have recently been in active litigation with competitors in each of the women’s health, 

35 

oncology and organ health fields, which involve considerable costs to us as well as management time and attention. If we 
are unable to compete successfully, we may be unable to increase or sustain our revenues or achieve profitability. 

We may not be successful in commercializing our cloud-based distribution model. 

We utilize a cloud-based distribution model to deploy our bioinformatics technology for use by other laboratories. 
Under this model, clinical laboratories around the world, including in the U.S., license our technology to develop and run 
their own NIPT or other molecular testing assays in their own facilities as LDTs, and then access our proprietary algorithms 
through our cloud-based Constellation software to analyze the assay results. In the diagnostics industry, the market for 
cloud-based  solutions  and  services  is  not  as  mature  as  the  market  for  on-premise  enterprise  software,  and  it  remains 
uncertain whether and to what extent our cloud-based distribution model will achieve and sustain high levels of customer 
demand and market acceptance. As of January 31, 2021, fewer than 20 licensees are using Constellation commercially to 
market NIPT products and one licensee is using Constellation commercially to market its non-invasive prenatal paternity 
test in the United States and internationally. The rate of adoption of our cloud-based distribution model continues to be 
slower than we anticipated, and depends on a number of factors, including the cost, performance and perceived value 
associated with our solution, as well as our ability to address security, privacy and regulatory requirements or concerns. In 
particular,  all  of  our  licensees  under  our  cloud-based  distribution  model  are  required  to  use  Illumina  sequencers  and 
reagents to run their tests that they develop based on our technology. As further described in the risk factor entitled “—
We rely on a limited number of suppliers or, in some cases, single suppliers, for some of our laboratory instruments and 
materials and may not be able to find replacements or immediately transition to alternative suppliers,” we are aware that 
Illumina has required our licensees to pay an additional license fee in certain jurisdictions in order to secure a supply 
agreement for the sequencers and reagents necessary to run NIPT under our cloud-based distribution model. Furthermore, 
Illumina  competes  with  us  through  its  subsidiary  Verinata,  and  may  not  charge  a  similar  license  fee  for  Verinata’s 
licensed-based offering to other laboratories. As a result, our potential or current licensees may be unable to commercially 
launch their tests under our cloud-based distribution model in a financially viable manner, which has dissuaded and could 
continue to dissuade potential or current licensees from licensing from us or launching a test based on our technology. In 
addition, if a test developed by any of our licensees under our cloud-based distribution model in the United States is found 
not to be an LDT, the licensee may not be able to market its test, and we would not receive the anticipated revenues from 
that licensee. 

We also do not know whether, over the long term, this model will result in benefits or cost savings at the levels 
that we anticipate or at all. For example, to the extent that any of our laboratory customers for whom we currently perform 
our tests entirely in our laboratory transition to our cloud-based distribution model, our revenues from such customers will 
decrease because we are not able to charge as high an amount per test as when we perform the entire test ourselves. If the 
lower revenues per test performed is not offset by a sufficient increase in volume of tests sold, our overall revenues will 
be lower, and our results of operations may be adversely affected. 

Among the risks to our business and results of operations from our Constellation model are the following: 

• 

• 

• 

• 

our and our licensees’ ability to obtain required regulatory authorizations from the FDA and international 
regulatory  agencies  as  further  described  in  the  risk  factor  entitled  “Reimbursement  and  Regulatory  Risks 
Related to Our Business—Failure to obtain necessary regulatory approvals may adversely affect our ability 
to expand our operations internationally, including our ability to continue commercializing our cloud-based 
distribution model;” 

supply constraints, including with respect to the blood collection tubes that are used for many of our tests, 
such  as  Panorama,  Signatera  and  Prospera,  and  that  are  supplied  by  Streck, Inc.,  or  Streck,  as  further 
described in the risk factor entitled “—We rely on a limited number of suppliers or, in some cases, single 
suppliers, for some of our laboratory instruments and materials and may not be able to find replacements or 
immediately transition to alternative suppliers;” 

allegations or potential third-party claims that the tests, based on our technology, developed by our licensees 
violate such third parties’ intellectual property rights; 

licensing  portions  of  our  proprietary  technology  to  third  parties  that  may  not  take  the  same  security 
precautions as we do to protect this information; and 

36 

• 

an inability to achieve anticipated benefits and costs savings. 

If we or other cloud-based solution providers experience security incidents, loss of customer data or disruptions 
in delivery or other problems, the market for cloud-based solutions in the diagnostics industry, including our solutions, 
may be adversely affected. Such events could also result in potential lawsuits and liability claims, which could have a 
material adverse effect on our business. If there is a reduction in demand for cloud-based solutions caused by technological 
challenges, weakening economic conditions, security or privacy concerns, competing technologies and products or other 
challenges, we may not be successful in executing our Constellation business model, and our results of operations may be 
adversely affected. 

We rely on internal and third-party data centers and platforms to host our laboratory and cloud-based software, and 
any interruptions of service or failures may impair our laboratory operations or the delivery of our cloud-based services 
and harm our business. 

We  currently  maintain  a  data  center  at  our  laboratory  facilities  in  San  Carlos,  California.  In  addition,  our 
proprietary bioinformatics algorithms are a crucial component of our test processing, and combine information derived 
from our mmPCR assay workflows with publicly available data from the broader scientific community to analyze and 
return test results. We host the significant majority of these algorithms on a cloud-based software platform pursuant to an 
agreement with DNAnexus, Inc., or DNAnexus, and both we and our Constellation licensees access our algorithms through 
the  DNAnexus  platform.  The  DNAnexus  platform  is  hosted  on  third-party  data  center  hosting  facilities  operated  by 
Amazon Web Services, or AWS, located primarily in the United States and in the European Union. These algorithms 
cannot currently be run other than through the DNAnexus platform; they are currently used to run our Panorama NIPT 
and NIPT analysis for our Constellation licensees, as well as Horizon, Signatera, Prospera and certain of our research and 
development activities, and we plan to utilize the platform for additional applications in the future. In the event of any 
technical problems that may arise in connection with our on-site data center, the DNAnexus platform or the AWS servers 
on which the DNAnexus platform is hosted, or difficulties in or termination of our relationship with DNAnexus, we could 
experience interruptions in our laboratory operations or our cloud-based services, and we and our Constellation licensees 
may be unable to access our proprietary algorithms and therefore be unable to process tests or conduct any other activities 
that  require  access  to  such  algorithms.  These  types  of  problems  may  be  caused  by  a  variety  of  factors,  including 
infrastructure changes, human or software errors, viruses, security attacks, fraud, spikes in customer usage and denial of 
service issues. We do not have any backup platform, server or other means to host our algorithms, and may be unable to 
find and implement an alternative platform that is satisfactory for our needs on commercially reasonable terms, in a timely 
manner, or at all. Interruptions in our operations or service may reduce our revenue, cause us to issue refunds, result in the 
loss of customers, cause laboratory licensees to terminate their contracts with us, adversely affect our ability to attract new 
laboratory licensees, or harm our reputation. We could also be exposed to potential lawsuits and liability claims. 

If our products do not perform as expected, our operating results, reputation and business will suffer. 

Our success depends on the market’s confidence that we can provide reliable, high-quality testing results. There 
is  no  guarantee  that  the  accuracy  and  reproducibility  we  have  demonstrated  to  date  will  continue  as  our  test  volumes 
continue to increase and our product portfolio continues to expand. We believe that our customers are particularly sensitive 
to test limitations and errors, including inaccurate test results and the need on occasion to perform second blood draws, or 
redraws, on patients, for which Panorama experiences a higher rate than advertised for other NIPTs. As a result, if our 
tests do not perform as expected or favorably in comparison to competitive tests, our operating results, reputation, and 
business will suffer. We may also become subject to legal claims arising from such limitations, errors, or inaccuracies. 

Our tests use a number of complex and sophisticated biochemical and bioinformatics processes, many of which 
are highly sensitive to external factors. An operational, technological or other failure in one of these complex processes, 
or fluctuations in external variables, may result in sensitivity or specificity rates that are lower than we anticipate or that 
vary between test runs, a higher than anticipated number of tests that require redraws or fail to produce results, or longer 
than expected turnaround times, which we have experienced and will likely continue to experience on occasion as a result 
of issues with laboratory equipment, components or materials or otherwise. In addition, we regularly evaluate and refine 
our testing processes, and any refinements we make may not improve our tests as we expect and may result in unanticipated 
issues that may adversely affect our test performance as described above, which we have experienced in the past. Such 

37 

operational, technical and other difficulties adversely affect test performance, may impact the commercial attractiveness 
of our products, and may increase our costs or divert our resources, including management’s time and attention, from other 
projects and priorities. Furthermore, any changes to our testing process may require us to use new or different suppliers or 
materials with whom or which we are unfamiliar, and which may not perform as we anticipate, and could cause delays, 
downtime or other operational issues. 

In addition, as further discussed in the risk factor entitled “If we are unable to successfully grow revenues for our 
current or future products or services in addition to Panorama, our business and results of operations may be adversely 
affected,” our Vistara NIPT is a relatively new test offering, as are Signatera and Prospera. Any failure to meet consumer 
expectations could harm our reputation. 

We rely on third-party laboratories to perform portions of our service offerings. 

Certain  of  our  tests,  or  components  of  our  tests,  are  performed  by  third-party  laboratories.  These  third-party 
laboratories are subject to contractual obligations to perform these services for us, but are not otherwise under our control. 
We therefore do not control the capacity and quality control efforts of these third-party laboratories other than through our 
ability to enforce contractual obligations on volume and quality systems, and we have no control over such laboratories’ 
compliance  with  applicable  legal  and  regulatory  requirements.  We  also  have  no  control  over  the  timeliness  of  such 
laboratories’ performance of their obligations to us, and third-party laboratories that we have contracted with have in the 
past had, and occasionally continue to have, issues with delivering results to us or resolving issues with us within the time 
frames we expected or established in our contracts with them, which sometimes results in longer than expected turnaround 
times for, or negatively impacts the performance of, these tests and services. Any natural or other disaster, acts of war or 
terrorism,  shipping  embargoes,  labor  unrest  or  political  instability  or  similar  events  at  one  or  more  of  our  third-party 
laboratories’ facilities that causes a loss of capacity would heighten the risks that we face. We may not have sufficient 
alternative backup if one or more of the third-party laboratories that we contract with are unable to satisfy their obligations 
to us with sufficient performance, quality and timeliness, including as a result of the COVID-19 pandemic. Changes to or 
termination of our agreements or inability to renew our agreements with these third-party laboratories or enter into new 
agreements with other laboratories that are able to perform such portions of our service offerings could impair, delay or 
suspend  our  efforts  to  market  and  sell  these  tests  and  services.  In  the  event  of  any  adverse  developments  with  these 
third-party laboratories or their ability to perform their obligations to us in a timely manner and in accordance with the 
standards that we and our customers expect, our ability to service our customers may be delayed, interrupted or otherwise 
adversely affected, which could result in a loss of customers and harm to our reputation. Furthermore, when these issues 
arise,  we  have  had  to  expend  time,  management  attention  and  other  resources  to  address  and  remedy  such  issues.  In 
addition, certain third-party payers, including some state Medicaid payers, that we are under contract with may take the 
position that sending out testing to third-party laboratories and billing for such tests is contrary to the terms of our provider 
agreement and may refuse to pay us for the testing. If any of these events occur, our business, financial condition and 
results of operations could suffer. Further, some state laws impose anti-markup restrictions that prevent an entity from 
realizing a profit margin on outsourced testing. If we or our subsidiaries are unable to markup outsourced testing, our 
revenues and operating margins may suffer. 

If we are unable to successfully grow revenues for our products or services in addition to Panorama and Horizon, our 
business and results of operations may be adversely affected. 

Our  ability  to  successfully  grow  revenues  for  products  or  services  in  addition  to  Panorama  and  Horizon,  is 
uncertain and is subject to many of the risks we face with respect to Panorama and Horizon. For example, the adoption 
and demand for such products or services may not grow as we expect; we may not be able to demonstrate that such products 
or services are equivalent or superior to competing products or services; third-party payers may not reimburse for our tests, 
or may set the amounts of such reimbursements at prices that do not allow us to cover our expenses; we may fail to compete 
successfully  in  the  relevant  product  markets,  or  our  laboratory  distribution  partners  may  choose  to  more  actively  or 
exclusively market tests by competitors; we may experience supply constraints; and we may fail to adequately protect our 
intellectual property relating to our products or others may claim we infringe their intellectual property rights, which has 
occurred, as disclosed elsewhere in these Risk Factors, with respect to litigation with Illumina relating to Panorama, with 
each of ArcherDX and Genosity relating to Signatera, with CareDx relating to Prospera and with Ravgen, Inc., relating to 
Panorama, Vistara, Signatera and Prospera. In addition, because our revenues from Horizon now represent a significant 

38 

proportion of our overall revenues, any adverse impact we experience with respect to Horizon could result in an impact to 
our overall revenues, or a component of such overall revenues; for example, a decline in our reimbursement rates for, and 
therefore our average selling price of, Horizon, could result in a decline in our overall blended average selling price. If we 
are not able to increase adoption of and grow revenues for our products or services, our business and results of operations 
may be adversely affected. 

We began offering our Vistara single-gene mutations screening test, our Signatera MRD test for research use 
only, and our twin pregnancies screening capability for Panorama, in 2017; our Signatera CLIA test and Prospera transplant 
rejection test, both on a limited basis, in 2019, with full-scale commercial launches of both Signatera and Prospera, among 
other products, in 2020. Our success with these offerings is subject to many of the risks affecting our business generally, 
as well as the inherent difficulties with launching a new offering and in new markets, including risks inherent in launching 
multiple new offerings simultaneously. Some of our offerings, such as Signatera and Prospera, while based upon our core 
molecular  diagnostic  technology,  are  in  fields  that  are  new  to  us;  and  others,  such  as  Vistara,  are  subject  to  the  risks 
inherent in commercializing a product with a laboratory partner. We have had to review and, in some cases, revise our 
processes,  procedures  and  agreements  with  our  business  partners  to  address  unforeseen  operational  issues  and  other 
contingencies, and will likely continue to do so as these areas of our business grow. We cannot assure you that our recent 
offerings will be successful. 

If either of our CLIA-certified laboratory facilities becomes inoperable, we will be unable to perform our tests and our 
business will be harmed. 

We currently operate laboratory facilities in Austin, Texas and in San Carlos, California, both of which process 
Panorama and Horizon tests, which together represent the significant majority of our revenues. Our efforts in oncology 
and organ health represent significant and increasing areas of focus for us, both operationally and financially; our Signatera 
and Prospera tests are currently only performed at our San Carlos facility, and we currently otherwise have no backup or 
redundant facility to perform these tests. Our San Carlos facility is situated near active earthquake fault lines. Either of our 
facilities  may  be  harmed  or  rendered  inoperable,  or  samples  could  be  damaged  or  destroyed,  by  natural  or  manmade 
disasters, including earthquakes, severe weather, flooding, power outages and contamination, including as a result of the 
COVID-19 pandemic, which may render it difficult or impossible for us to perform our tests for some period of time. The 
inability  to  perform  our  tests  or  the  backlog  of  tests  that  could  develop  if  either  our  San  Carlos  or  Austin  facility  is 
inoperable for even a short period of time may result in the loss of customers or harm our reputation. 

We rely on a limited number of suppliers or, in some cases, single suppliers, for some of our laboratory instruments 
and materials and may not be able to find replacements or immediately transition to alternative suppliers. 

We  have  sourced  and  will  continue  to  source  components  of  our  technology,  including  sequencers,  reagents, 
tubes and other laboratory materials, from third parties. In particular, our sequencers, many of our reagents, including for 
Panorama, Horizon and Signatera as described below, and our blood collection tubes, are sole sourced. 

For example, our molecular diagnostics tests are currently only validated to perform on Illumina’s sequencing 
platform; in addition, Illumina is currently the sole supplier of our sequencers and related reagents for Panorama, Horizon, 
Signatera and Prospera, along with certain hardware and software, pursuant to a supply agreement that expires in May 
2030. Without sequencers and the related reagents, we would be unable to run our tests and commercialize our products. 
In addition, all of the licensees under our cloud-based distribution model do not have alternatives other than to use Illumina 
sequencers and reagents to run the tests that they develop based on our technology. In addition, Illumina and Sequenom, 
which was acquired by LabCorp, have entered into a patent pooling agreement pursuant to which both parties have pooled 
their intellectual property directed to NIPT. We understand from public filings that under the patent pooling agreement, 
Illumina has the exclusive worldwide rights to, among other things, license third-party laboratories to develop and sell 
NIPTs utilizing the pooled intellectual property and to enforce the pooled intellectual property against suspected infringers. 
Illumina has granted us certain rights to Illumina’s intellectual property related to NIPT, including the pooled intellectual 
property, for running our own tests; however, we do not have an express license to grant rights under the pooled intellectual 
property to the licensees under our cloud-based distribution model. We are aware that Illumina has required our licensees, 
in  order  to  secure  a  supply  agreement  for  the  sequencers  and  reagents  necessary  to  run  NIPT  under  our  cloud-based 
distribution model, to pay an additional fee for a license under the pooled intellectual property in jurisdictions in which 
Illumina believes certain of the pooled intellectual property is enforceable. This additional fee has dissuaded and could 
continue to dissuade potential or current licensees from licensing from us or launching a test based on our technology. In 

39 

addition,  we  have  recently  been  involved  in  patent  infringement  litigation  against  Illumina,  as  further  described  in 
“Note 8—Commitments  and  Contingencies—Legal  Proceedings”  in  the  Notes  to  Consolidated  Financial  Statements, 
which  we  and  Illumina  have  settled.  In  addition,  Illumina  directly  competes  with  us  in  the  NIPT  market  through  its 
subsidiary,  Verinata.  We  understand  Illumina  supplies  the  same  or  similar  sequencers  and  consumables  to  Verinata. 
Because of Illumina’s ownership of Verinata, we face increased risk and uncertainty regarding continuity of a successful 
working relationship with Illumina under our supply agreement, as well as in our ability to compete with Verinata in the 
marketplace  in  view  of  economic  advantages  enjoyed  by  Verinata  with  respect  to  the  cost  of  sequencers  and  related 
consumables.  Furthermore,  Illumina  has  entered  into  an  agreement  to  acquire  GRAIL,  a  company  focused  on  early 
detection of cancer, and we may be subject to risks similar to, and which may compound, those described above if such 
acquisition is completed. Our failure to maintain a continued supply of the sequencers and reagents, along with the right 
to use certain hardware and software, would adversely impact our business, financial condition, and results of operations. 
In particular, while we are seeking to validate our tests on additional sequencing platforms, such as under our license 
agreement with BGI Genomics Co., Ltd., or BGI Genomics, we have not, to date, validated any alternative sequencing 
platform  on  which  our  testing  could  be  run  in  a  commercially  viable  manner.  These  efforts  will  require  significant 
resources, expenditures and time and attention of management, and there is no guarantee that we will be successful in 
implementing any such sequencing platforms in a commercially sustainable way. We also cannot guarantee that we will 
appropriately prioritize or select alternative sequencing platforms on which to focus our efforts, in particular given our 
limited product and research and development resources and various business initiatives, which could result in increased 
costs and delayed timelines or otherwise impact our business and results of operations. 

In addition, our Panorama test is currently only validated to be performed using Streck’s blood collection tubes, 
and Streck is the sole supplier of the blood collection tubes included in our Panorama test under a supply arrangement with 
Streck under which we are required to exclusively use Streck tubes. Similarly, all of the licensees under our cloud-based 
distribution model also have no current alternative but to use these blood collection tubes to run the tests that they develop 
based on our technology. We also only use Streck tubes for the primary analysis of Signatera results, and for our Prospera 
test. Furthermore, the blood collection tubes supplied by Streck are intended for research use only and are labeled as RUO. 
Our sequencers, sourced from Illumina, as well as certain other reagents we use for Panorama and our other tests, are also 
labeled as RUO. As discussed further in the risk factor entitled “Reimbursement and Regulatory Risks Related to Our 
Business—Changes in the way the FDA regulates the reagents, other consumables, and testing equipment we use when 
developing, validating, and performing our tests could result in delay or additional expense in bringing our tests to market 
or performing such tests for our customers,” the FDA may determine that a product labeled RUO is, nonetheless, intended 
to be used diagnostically, and could take enforcement action against the manufacturer of the product. If this were to occur 
with respect to Streck, Illumina or any of our other suppliers of RUO products, we could be required to obtain one or more 
alternative sources of these products, and we may not be able  to do so on commercially reasonable terms or at all. In 
addition, Streck’s blood collection tubes have not been registered as a medical device in all countries in which we market 
our Panorama test. As discussed in the risk factor entitled “Reimbursement and Regulatory Risks Related to Our Business—
Failure to obtain necessary regulatory approvals may adversely affect our ability to expand our operations internationally, 
including our ability to continue commercializing our cloud-based distribution model,” the regulatory authorities in some 
of these countries may determine that such registration is required, which could impact our ability to offer Panorama in 
such countries. Furthermore, because our licensees under our cloud-based distribution model also exclusively use such 
sole-sourced components to run the tests they develop based on our technology, and our laboratory distribution partners 
must use certain of such sole-sourced components in order to utilize our tests, any enforcement action against the supplier 
by the FDA or any other regulatory authority in the jurisdictions in which our licensees and laboratory distribution partners 
are located could have an adverse impact on our business. 

Because we rely on third-party manufacturers, we do not control the manufacture of these components, including 
whether  such  components  will  meet  our  quality  control  requirements,  nor  the  ability  of  our  suppliers  to  comply  with 
applicable legal and regulatory requirements. In many cases, our suppliers are not contractually required to supply these 
components to the quality or performance standards that we require. If the supply of components we receive does not meet 
our quality control or performance standards, we may not be able to use the components, or if we use them not knowing 
that they are of inadequate quality, which occasionally occurs with respect to certain reagents, our tests may not work 
properly or at all, or may provide erroneous results, and we may be subject to significant delays caused by interruption in 
production or manufacturing or to lost revenue from such interruption or from spoiled tests. In addition, any natural or 

40 

other disaster, acts of war or terrorism, shipping embargoes, labor unrest or political instability or similar events at our 
third-party manufacturers’ facilities that cause a loss of manufacturing capacity would heighten the risks that we face. 

In the event of any adverse developments with our sole suppliers, or if any of our sole suppliers modifies any of 
the  components  they  supply  to  us,  our  ability  to  supply  our  products  may  be  interrupted,  and  obtaining  substitute 
components could be difficult or require us to re-design or re-validate our products. In addition, if we obtain FDA clearance, 
approval or authorization for any of our tests as an in vitro diagnostic, or IVD, such issues with suppliers or the components 
that we source from suppliers could affect our commercialization efforts for such an IVD, as further described in the risk 
factor  entitled  “Reimbursement  and  Regulatory  Risks  Related  to  Our  Business—If  the  FDA  were  to  begin  actively 
regulating our tests, we could incur substantial costs and delays associated with trying to obtain premarket clearance or 
approval and incur costs associated with complying with post-market controls.” Our failure to maintain a continued supply 
of components, or a supply that meets our quality control requirements, or changes to or termination of our agreements or 
inability to renew our agreements with these parties or enter into new agreements with other suppliers, particularly in the 
case of sole suppliers such as Streck and Illumina, could result in the loss of access to important components of our tests 
and impact our test performance or affect our ability to perform our tests in a timely manner or at all, which could impair, 
delay or suspend our commercialization activities. In the event that we transition to a new supplier from any of our sole 
suppliers, doing so could be time-consuming and expensive, may result in interruptions in our ability to supply our products 
to  the  market,  could  affect  the  performance  of  our  tests  or  could  require  that  we  re-validate  our  affected  tests  using 
replacement equipment and supplies, which could delay the performance of our tests and result in increased costs. Any of 
these occurrences could have a material adverse effect on our business, financial condition and results of operations. 

We  rely  on  commercial  courier  delivery  services  to  transport  samples  to  our  facilities  in  a  timely  and  cost-efficient 
manner and if these delivery services are disrupted, our business will be harmed. 

Our core business depends on our ability to quickly and reliably deliver test results to our customers. We typically 
receive blood samples for analysis at our laboratory facilities within days of collection from the patient. Disruptions in 
delivery service – whether due to error by the courier service, labor disruptions, bad weather, natural disaster, terrorist acts 
or threats or for other reasons – some of which we have experienced in the past, could adversely affect specimen integrity, 
our ability to process or store samples in a timely manner and to service our customers, and ultimately our reputation and 
our business. In addition, if we are unable to continue to obtain expedited delivery services on commercially reasonable 
terms, our operating results may be adversely affected. 

Security  breaches,  loss  of  data  and  other  disruptions,  including  with  respect  to  cybersecurity,  could  compromise 
sensitive information related to our business or prevent us from accessing critical information and expose us to liability, 
which could adversely affect our business and reputation. 

In the ordinary course of our business, we collect and store sensitive data, including legally-protected personal 
information, such as test results and other patient health information, credit card and other financial information, insurance 
information, and personally identifiable information. We also store sensitive intellectual property and other proprietary 
business  information,  including  that  of  our  customers,  payers  and  collaboration  partners.  We  are  highly  dependent  on 
information technology networks and systems, including a combination of on-site systems, managed data center systems 
and  cloud-based  data  center  systems,  and  the  Internet,  to  securely  process,  transmit,  and  store  a  wide  variety  of 
business-critical information, including research and development information, commercial information and business and 
financial information. We also communicate sensitive data, including patient data, telephonically, through our website, 
through facsimile, through integrations with third party electronic medical records systems, and through relationships with 
third  party  vendors  and  their  subcontractors,  both  in  the  United  States  and  internationally.  The  laws  of  some  foreign 
countries do not protect data privacy to the same extent as the laws of the United States. 

The  secure  processing,  storage,  maintenance  and  transmission  of  this  critical  information  are  vital  to  our 
operations and business strategy. Although we take measures to protect sensitive information from unauthorized access, 
use or disclosure, our information technology and infrastructure, and that of our technology and other third-party service 
providers and their subcontractors, are nevertheless inherently vulnerable, to some extent, to cyber-attacks by hackers or 
viruses  or  breaches  due  to  employee  error,  technical  error,  malfeasance  or  other  disruptions.  Any  such  breach  or 
interruption, whether of our systems or that of our third-party service providers or their subcontractors, could compromise 

41 

our data security, and the information we store could be inaccessible by us or could be accessed by unauthorized parties, 
publicly disclosed, lost or stolen. Any such interruption in access, improper access, disclosure, modification, or other loss 
of information could result in legal claims or proceedings, liability or penalties under laws and regulations that protect the 
privacy  of personal  information,  such  as  the  Health  Insurance  Portability  and  Accountability  Act of 1996, or HIPAA, 
European data privacy regulations, such as the General Data Protection Regulation, or GDPR, or state privacy regulations, 
such as the California Consumer Privacy Act. We may be required to comply with state breach notification laws, become 
subject to mandatory corrective action, or be required to verify the correctness of database contents. Unauthorized access, 
loss or dissemination could also disrupt our operations, including our ability to perform tests, provide test results, bill 
payers or patients, process claims and appeals, provide customer assistance services, conduct research and development 
activities,  develop  and  commercialize  tests,  collect,  process  and  prepare  company  financial  information,  provide 
information  about  our  tests,  and  manage  the  administrative  aspects  of  our  business,  any  of  which  could  damage  our 
reputation and adversely affect our business. In addition, these breaches and other inappropriate access can be difficult to 
detect, and any delay in identifying them may compound these adverse consequences. Any such breach could also result 
in the compromise of our trade secrets and other proprietary information, which could adversely affect our competitive 
position. We are also subject to these risks as a result of our relationships with third party vendors and their subcontractors, 
whose systems may be breached and may cause our sensitive data, including patient data, to be compromised. We have 
on occasion experienced such disruptions. 

For example, in May 2019, we were notified of a data security incident that compromised the computer systems 
of Retrieval-Masters Creditors Bureau, Inc. d/b/a American Medical Collection Agency, or AMCA, one of our third-party 
vendors, and affected a limited number of our patients whose data was stored in AMCA’s systems. While the accessed 
data  did  not  include  Social  Security  numbers,  the  credit  card  information  of  a  small  number  of  the  patients  was 
compromised. We notified the affected individuals as required by HIPAA. Further, in August 2020, we were notified of a 
data security incident that compromised the systems of another third-party vendor, which affected a number of our patients 
whose data was stored in the vendor’s systems. The compromised information included protected health information of 
such patients, but did not include Social Security numbers, financial information or test results. The vendor notified the 
affected individuals as required by HIPAA. 

Our  cloud-based  distribution  model  adds  additional  data  privacy  risk,  as  certain  personal  health  and  other 
information may be sent to and stored in the cloud by our laboratory licensees, many of which are located outside of the 
United  States.  We  contractually  prohibit  our  licensees  from  sending  personally-identifiable  information  to  our  cloud 
servers, and the vendor that hosts our software in the cloud is contractually required to comply with data privacy laws, 
such  as HIPAA  and  GDPR. However, we cannot  be  certain  that  these  third parties will  comply with  the  terms of our 
agreements, nor that they will not experience security breaches or other disruptions. 

The marketing, sale, and use of Panorama, Horizon and our other products could result in substantial damages arising 
from product liability or professional liability claims that exceed our resources. 

The marketing, sale and use of Panorama, Horizon and our other products could lead to product liability claims 
against us if someone were to allege that our test failed to perform as it was designed or as claimed in our promotional 
materials, was performed pursuant to incorrect or inadequate laboratory procedures, if we delivered incorrect or incomplete 
test  results,  or  if  someone  were  to  misinterpret  test  results.  In  addition,  we  may  be  subject  to  liability  for  errors  in,  a 
misunderstanding of, or inappropriate reliance upon, the information we provide, or for failure to provide such information, 
in connection with our marketing and promotional activities or as part of the results generated by Panorama, Horizon and 
our other products. For example, Panorama could provide a low-risk result which a patient or physician may rely upon to 
make a conclusion about the health of the fetus, which may, in fact, have the condition for which we delivered a low-risk 
result because the Panorama result was a so-called false negative. Even though Panorama and our other tests are highly 
accurate, they are not 100% accurate and we may report false negative results. If the resulting baby with the condition is 
born, the family may file a lawsuit against us claiming product or professional liability, as has happened in the past and 
may happen in the future. A product liability or professional liability claim could result in substantial damages and be 
costly  and  time-consuming  for  us  to  defend.  Although  we  maintain  product  and  professional  liability  insurance,  our 
insurance may not fully protect us from the financial impact of defending against product liability or professional liability 
claims or any judgments, fines or settlement costs arising out of any such claims. Any product liability or professional 
liability claim brought against us, with or without merit, could increase our insurance rates, cause our insurance coverage 

42 

to  be  terminated  or  prevent  us  from  securing  insurance  coverage  in  the  future.  Additionally,  any  product  liability  or 
professional  liability  lawsuit  could  harm  our  reputation,  result  in  a  cessation  of  our  services  or  cause  our  partners  to 
terminate our agreements with them, any of which could adversely impact our results of operations. 

If we are unable to successfully scale our operations, our business could suffer. 

Our overall test volumes grew from approximately 668,600 to 804,300 and further to 1,026,500 tests processed 
during the years ended December 31, 2018, 2019 and 2020, respectively, and since 2009 we have launched 16 product 
offerings, four of them in 2017 alone and both Signatera and Prospera, among other products, in 2020. In addition, we 
regularly evaluate and refine our testing process, often significantly updating our workflows, as with Panorama in 2017 
and Horizon in 2018. As our test volumes and product offerings continue to grow, we will need to continue to ramp up 
our  testing  capacity  and  implement  increases  in  scale,  such  as  increased  headcount,  additional  or  new  equipment, 
laboratory space and qualified laboratory personnel, increased office and laboratory space, expanded customer service 
capabilities, billing and systems process improvements, enhanced controls and procedures and expanded or internal quality 
assurance  program  and  technology  platform.  The  value  of  Panorama,  Horizon  and  our  other  products  depends  on  our 
ability to perform the tests on a timely basis and at an exceptionally high standard of quality, and on maintaining our 
reputation  for  such  timeliness  and  quality.  Failure  to  implement  necessary  procedures,  transition  to  new  facilities, 
equipment or processes or to hire the necessary personnel in a timely and effective manner could result in higher processing 
costs or an inability to meet market demand, or could otherwise affect our operating results, as we have experienced in the 
past. 

In addition, our efforts to scale our operations may be unable to keep pace with an increase in the frequency of 
our launches of new or enhanced products and services. Since 2017, we have launched eight new products, three in markets 
or industries new to us. As we continue to launch additional offerings and product enhancements, we will need to manage 
our resources among various initiatives, and such competing priorities could lead to delays in one or more of our business 
initiatives. Conversely, to the extent that we scale our operations, infrastructure and other resources but do not ultimately 
meet  our  anticipated  timelines  in our product  development  efforts,  we  will  experience higher  costs  and  expenses  than 
necessary  until  our  project  timelines  and  operational  resources  become  aligned.  We  may  also,  intentionally  or 
unintentionally, allocate resources to new products or initiatives in a manner disproportionate to the amount of revenue 
that such initiatives generate compared to our existing or core offerings. We cannot assure you that our efforts to scale our 
commercial operations will not negatively affect the quality of our test process or results, or that we will be successful in 
managing the growing complexity of our business operations. 

To  execute  our  growth  plan,  we  must  attract  and  retain  highly  qualified  personnel.  Competition  for  these 
personnel is intense, especially for sales, scientific, medical, laboratory, research and development and other technical 
personnel, and especially in the San Francisco Bay Area where we have an office and laboratory facilities, and the turnover 
rate of such personnel can be high. We have from time to time experienced, and we expect to continue to experience, 
difficulty  in  hiring  and  retaining  employees  with  appropriate  qualifications.  Many  of  the  companies  with  which  we 
compete for highly qualified personnel have greater resources than we have. If we hire employees from competitors or 
other  companies,  their  former  employers  may  attempt  to  assert  that  these  employees  or  we  have  breached  their  legal 
obligations to their former employers, which occurs from time to time. In addition, job candidates and existing employees 
in  the  San  Francisco  Bay  Area  often  consider  the  value  of  the  equity  awards  they  receive  in  connection  with  their 
employment. To the extent that our current or potential employees perceive the value of our equity awards to be low, our 
ability to recruit, retain and motivate highly skilled employees may be adversely affected, which could then have an adverse 
effect on our business and future growth prospects. Furthermore, to the extent that we are unable to retain our employees 
and they leave our company to join one of our competitors, we cannot assure you that any invention, non-disclosure or 
non-compete agreements we have in place will provide meaningful protection against a departing employee’s unauthorized 
use or disclosure of our confidential information, as further discussed in “—Risks Relating to our Intellectual Property—
If we are not able to adequately protect our trade secrets and other proprietary information, the value of our technology 
and products could be significantly diminished.” 

In addition, our growth may place a significant strain on our operating and financial systems and our management, 
sales, marketing and administrative resources. As a result of our growth, our operating costs may escalate faster than we 
anticipate, we may face difficulties in obtaining additional office or laboratory space, and some of our internal systems 

43 

may need to be enhanced or replaced. If we cannot effectively manage our expanding operations and our costs, we may 
not be able to grow successfully or we may grow at a slower pace, and our business could be adversely affected. 

If our sales, distribution, development or other partnerships are not successful and we are not able to offset the resulting 
impact through our own efforts or through agreements with new partners, our commercialization activities may be 
impaired and our financial results could be adversely affected. 

Part of our business strategy is to develop relationships with laboratory and other partners to develop or sell our 
products,  both  in  the  United  States  and  internationally.  For  example,  we  have  entered  into  an  agreement  with  BGI 
Genomics pursuant to which, among others, we will commercialize Signatera in China and develop reproductive health 
tests on BGI Genomics’s sequencing platform; and an agreement with Foundation Medicine to develop and commercialize 
personalized circulating tumor DNA monitoring assays for use by biopharmaceutical and clinical customers who order 
Foundation Medicine’s companion diagnostic cancer test. Developing and commercializing products with third parties 
reduces our control over such development and commercialization efforts and subjects us to the various risks inherent in 
a joint effort with a third party, such as delays, operational issues, technical difficulties and other contingencies outside of 
our influence or control. Distributing Panorama, Signatera and our other products through partners reduces our control 
over our revenues, our market penetration and our gross margin on sales by the partner if we could have otherwise made 
that sale through our direct sales force. The financial condition of these third parties could weaken, or they could terminate 
their relationship with us and/or stop selling our products, as has happened in the past; reduce their marketing efforts in 
respect of our products; develop and commercialize or otherwise sell competing products in addition to or in lieu of our 
tests, as has also occurred; merge with or be acquired by a competitor of ours or a company that chooses to de-prioritize 
or cease the efforts to develop, sell or otherwise partner with us on our products; or otherwise breach their agreements 
with us. For example, as further described in “Note 3—Revenue Recognition—Licensing and Other Revenues—Qiagen” 
of  our  consolidated  financial  statements,  we  had  entered  into  a  license,  distribution  and  development  agreement  with 
Qiagen pursuant to which, among others, Qiagen would distribute an NIPT based on our Panorama test on a sequencer to 
be  developed  by  us  and  Qiagen;  however,  Qiagen  thereafter  discontinued  the  development  of  its  Next  Generation 
Sequencing Platform and instead partnered with Illumina to develop next-generation sequencing based tests. Furthermore, 
our laboratory partners may misappropriate our trade secrets or use our proprietary information in such a way as to expose 
us to litigation and potential liability; and our compliance risk may increase to the extent that we are responsible, or deemed 
responsible,  for  our  partners’  sales  and  marketing  activities.  Disagreements  or  disputes  with  our  partners,  including 
disagreements  over  customers,  proprietary  rights  or  our  or  their  compliance  with  contractual  obligations,  might  cause 
delays or impair the commercialization of Panorama, Signatera or our other tests, lead to additional responsibilities for us 
with  respect  to  new  tests,  or  result  in  litigation  or  arbitration,  any  of  which  would  divert  management  attention  and 
resources and be time-consuming and expensive. As is typical for companies in our industry, we are continually evaluating 
and pursuing various strategic or commercial partnerships, relationships, or collaborations, some of which may involve 
the sale and issuance of our common stock, which could result in additional dilution of the percentage ownership of our 
stockholders and could cause the price of our common stock to decline. 

If our partnerships are not successful, our ability to increase sales of our products and to successfully execute our 

strategy could be compromised. 

Our financial condition and results of operations may be adversely affected by international regulatory and business 
risks. 

As we expand our operations, including by offering our tests in other countries, we are increasingly subject to 
varied and complex foreign and international laws and regulations due to operating, offering our products, or contracting 
with  employees,  contractors  and  other  service  providers  in  various  other  countries.  Compliance  with  these  laws  and 
regulations often involves significant costs and may require changes in our business practices that may result in reduced 
revenues and adversely affect our operating results. 

We  are  subject  to  the  Foreign  Corrupt  Practices  Act  of  1977,  as  amended,  or  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.  Our  reliance  on  independent 
laboratories to sell Panorama and other products internationally demands a high degree of vigilance in maintaining our 
policy against participation in corrupt activity, because these distributors could be deemed to be our agents and we could 
be held responsible for their actions. Other U.S. companies in the medical device and pharmaceutical field have faced 

44 

criminal penalties under the FCPA for allowing their agents to deviate from appropriate practices in doing business with 
foreign government officials. We are also subject to similar anti-bribery laws in the jurisdictions in which we operate, 
including the United Kingdom’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. 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 we could be subject to severe penalties, including criminal and civil penalties, 
disgorgement,  and  other  remedial  measures,  any  of  which  could  result  in  a  material  adverse  effect  on  our  business, 
prospects, financial condition, or results of operations. 

In  addition,  our  international  activities  are  subject  to  U.S.  economic  and  trade  sanctions,  which  restrict  or 
otherwise limit our ability to do business in certain designated countries. Other limitations, such as restrictions on the 
import into the United States or the export to other countries of tissue or genetic data necessary for us to perform our tests, 
or restrictions on importation and circulation of blood collection tubes or other equipment or supplies by countries outside 
of the United States, may limit our ability to offer our tests internationally. We may also face competition from companies 
located in the countries in which we or our partners or licensees offer our tests, and in which we may be at a competitive 
disadvantage because the country may favor a local provider or for other reasons. 

By operating internationally, we may experience longer accounts receivable payment cycles and difficulties in 
collecting accounts receivable; realize lower margins due to lower pricing in many countries; incur potentially adverse tax 
consequences, including the complexities of foreign value added tax systems, tax inefficiencies related to our corporate 
structure  and  restrictions  on  the  repatriation  of  earnings;  experience  financial  accounting  and  reporting  burdens  and 
complexities; experience difficulties in staffing and managing foreign operations, including under labor and employment 
laws and regulations that are new or unfamiliar to us; be subject to trade barriers such as tariffs, quotas, preferential bidding 
or  import  or  export  licensing  requirements;  be  exposed  to  political,  social  and  economic  instability  abroad,  including 
terrorist attacks and security concerns; be exposed to fluctuations in currency exchange rates; and experience reduced or 
varied protection for intellectual property rights and practical difficulties in enforcing intellectual property and other rights, 
including with respect to assignment of inventions to us by our consultants in foreign jurisdictions. 

Outside of the United States we enlist local and regional laboratories, contract employees and other contracted 
service  providers  to  assist  with  various  aspects  of  our  business  operations,  including  blood  draws,  engineering,  sales, 
marketing,  billing  and  customer  support.  Subject  to  regulatory  clearance  where  required,  we  also  contract  with 
international licensees to run the molecular portion of our tests in their own labs and then access our algorithm for analysis 
of  the  resulting  data  through  our  cloud-based  Constellation  platform.  Locating,  qualifying  and  engaging  additional 
distribution partners and local laboratories with local industry experience and knowledge is necessary to effectively market 
and  sell  our  tests  outside  of  the  United  States.  We  may  not  be  successful  in  finding,  attracting  and  retaining  such 
distribution partners  or  laboratories, or we may not be  able  to  enter  into  such  arrangements on favorable  terms.  Sales 
practices and other activities utilized by our distribution partners, contract employees and other service providers, some of 
which may be locally acceptable, may not comply with relevant standards required under United States laws that apply to 
our operations overseas, including through third parties, which could create additional compliance risk. Our training and 
compliance program and our other internal control policies and procedures, and our contractual terms with these third 
parties,  may  not  always  protect  us  from  acts  committed  by  our  employees,  contractors,  partners  or  agents  abroad. 
Non-compliance by us or our employees, contractors, partners or agents, whether maliciously or in error, of any applicable 
laws or regulations could result in fines or penalties, or adversely affect our ability to operate and grow our business. Even 
if  we  are  able  to  effectively  manage  our  international  operations,  if  our  distribution  partners  and  local  and  regional 
laboratory licensees are unable to effectively manage their  businesses, our business and results of operations could be 
adversely affected. Furthermore, the legal landscape governing advertising, promotional and other marketing activities can 
vary widely from jurisdiction to jurisdiction, and is often more complex, less clear or less developed than in the United 
States. If our marketing activities are found to be in violation of local laws, regulations or practices, we may be subject to 
fines and other penalties, and may be required to cease marketing or commercialization activities in such jurisdiction. If 
our sales and marketing efforts are not successful outside of the United States, we may not achieve market acceptance for 
our tests outside of the United States, which would harm our business. 

45 

Operating internationally requires significant management attention and financial resources. We cannot be certain 
that  the  investment  and  additional  resources  required  to  increase  international  revenues  or  expand  our  international 
presence will produce desired levels of revenues or profitability. 

If we lose the services of our founder and Executive Chairman or other members of our senior management team, we 
may not be able to execute our business strategy. 

Our success depends in large part upon the continued service of our senior management team. In particular, our 
founder  and  Executive  Chairman,  Matthew  Rabinowitz,  as  well  as  Steve  Chapman,  our  Chief  Executive  Officer,  are 
critical to our vision, strategic direction, culture, products and technology. Although Dr. Rabinowitz spends significant 
time with us and is active in our management, he is no longer our Chief Executive Officer. In addition, we do not maintain 
key-man insurance for Dr. Rabinowitz, Mr. Chapman or any other member of our senior management team. The loss of 
our founder and Executive Chairman, our Chief Executive Officer or one or more other members of our senior management 
team could have an adverse effect on our business. 

We  may  engage  in  acquisitions,  dispositions  or  other  strategic  transactions  that  could  disrupt  our  business,  cause 
dilution to our stockholders or reduce our financial resources. 

From time to time, we may enter into transactions to acquire or dispose of businesses, products or technologies 
or to engage in other strategic transactions. Because we have not made any such acquisitions to date, our ability to do so 
successfully is unproven. Even if we identify suitable transactions, we may not be able to complete such transactions on 
favorable  terms  or  at  all.  Any  acquisitions  or  other  strategic  transactions  we  consummate  may  not  strengthen  our 
competitive position, and these transactions may be viewed negatively by customers or investors. We may decide to incur 
debt in connection with an acquisition or issue shares of our common stock or other equity securities to the stockholders 
of the acquired company, which would cause dilution to our existing stockholders. We could incur losses resulting from 
such  strategic  transactions,  including  undiscovered  liabilities  of  an  acquired  business  that  are  not  covered  by  any 
indemnification we may obtain from the seller. In addition, we may not be able to successfully integrate any acquired 
personnel, technologies and operations into our existing business in an effective, timely and non-disruptive manner. Any 
dispositions may also cause us to lose revenue and may not strengthen our financial position. Strategic transactions may 
also divert management attention from day-to-day responsibilities, increase our expenses, result in accounting charges, 
and reduce our cash available for operations and other uses. We cannot predict the number, timing or size of future strategic 
transactions or the effect that any such transactions might have on our operating results. 

We  may  need  to  raise  additional  funds  through  public  or  private  equity  or  debt  financings,  corporate 

collaborations or licensing arrangements to continue to fund or expand our operations. 

Our actual liquidity and capital funding requirements will depend on numerous factors, including: 

• 

• 

• 

• 

• 

• 

• 

our ability to achieve broader commercial success with Panorama, Horizon and our other products; 

the costs and success of our research, development, and commercialization efforts for potential new 
products; 

our ability to obtain more extensive coverage and reimbursement for our tests, including in the average-risk 
patient population and for microdeletions screening in NIPT, as well as in additional indications in oncology 
as we continue to expand our offerings in that field; 

our ability to generate sufficient revenues from our cloud-based distribution model; 

our ability to collect on our accounts receivable; 

our need to finance capital expenditures and further expand our clinical laboratory operations; 

our ability to manage our operating costs; and 

46 

• 

the timing and results of any regulatory authorizations that we are required to obtain for our tests. 

Additional capital, if needed, may not be available on satisfactory terms or at all. Furthermore, any additional 
capital  raised  through  the  sale  of  equity  or  equity-linked  securities,  or  grant  of  equity  or  equity-linked  securities  in 
connection with any debt financing, will dilute stockholders’ ownership interests in us and may have an adverse effect on 
the price of our common stock. In addition, the terms of any financing may adversely affect stockholders’ holdings or 
rights. Debt financing, if available, may include restrictive covenants, and may impose other constraints on us and our 
operations,  as  was  the  case  under  our  2017  Term  Loan  with  OrbiMed.  To  the  extent  that  we  raise  capital  through 
collaborations  and  licensing  arrangements,  it  may  be  necessary  to  relinquish  some  rights  to  our  technologies  or  grant 
licenses on terms that may not be favorable to us. 

If we are not able to obtain adequate funding when needed, we may have to delay development programs or sales 
and marketing initiatives. In addition, we may have to work with a partner on one or more of our tests or programs, which 
could lower the economic value of those programs to our company. 

We have incurred substantial indebtedness that may decrease our business flexibility, access to capital, and/or increase 
our borrowing costs, which may adversely affect our operations and financial results. 

In April 2020, we issued $287.5 million aggregate principal amount of 2.25% Convertible Senior Notes due 2027, 

or the Convertible Notes. Our indebtedness may: 

• 

• 

• 

• 

• 

• 

limit our ability to borrow additional funds for working capital, capital expenditures, acquisitions or other 
general business purposes; 

limit our ability to use our cash flow or obtain additional financing for future working capital, capital 
expenditures, acquisitions or other general business purposes; 

require us to use a substantial portion of our cash flow from operations to make debt service payments; 

limit our flexibility to plan for, or react to, changes in our business and industry; 

place us at a competitive disadvantage compared to our less leveraged competitors; and 

increase our vulnerability to the impact of adverse economic and industry conditions. 

Further,  the  indenture  governing  the  Convertible  Notes  does  not  restrict  our  ability  to  incur  additional 
indebtedness  and  we  and  our  subsidiaries  may  incur  substantial  additional  indebtedness  in  the  future,  subject  to  the 
restrictions contained in any future debt instruments existing at the time, some of which may be secured indebtedness. 

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

DNA testing, like that conducted using Panorama, Horizon, Signatera, and our other products, has raised ethical, 
legal and social issues regarding privacy and the appropriate uses of the resulting information. Governmental authorities 
could, for social or other purposes, limit or regulate the use of genomic information or genomic testing or prohibit testing 
for genetic predisposition to certain conditions, particularly for those that have no known cure. Patients may also refuse to 
use genetic tests even if permissible, for similar reasons; they may also refuse genetic testing due to concerns regarding 
eligibility for life or other insurance. Ethical and social concerns may also influence U.S. and foreign patent offices and 
courts with regard to patent protection for technology relevant to our business. These and other ethical, legal and social 
concerns may limit market acceptance of our tests or reduce the potential markets for services and products enabled by 
our technology platform, either of which could harm our business. 

47 

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited. 

We have a significant amount of net operating loss, or NOL, carryforwards that can be used to offset potential 
future taxable income and related income taxes. As of December 31, 2020, we had federal and state NOL carryforwards 
of approximately $727.2 million and $412.9 million, respectively, which, if not utilized, begin to expire in 2027 and 2028, 
respectively. Approximately $407.3 million of these federal NOLs can be carried forward indefinitely. We also had federal 
research and development credit carryforwards of approximately $21.4 million, which begin to expire in 2027, and state 
research and development credit carryforwards of approximately $16.9 million, which can be carried forward indefinitely. 
Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change” 
(generally  defined  as  a  greater  than  50%  change,  by  value,  in  equity  ownership  over  any  three-year  period),  the 
corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change 
income or taxes may be limited. We may experience ownership changes in the future as a result of shifts in our stock 
ownership, some of which may not be within our control. Our ability to use these carryforwards could be limited if we 
experience an “ownership change.” 

Our estimates of total addressable market opportunity and forecasts of market growth may prove to be inaccurate, and 
even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates. 

Total addressable market opportunity estimates and growth forecasts are subject to significant uncertainty and 
are based on assumptions and estimates that may not prove to be accurate. Our publicly announced estimates and forecasts 
relating to the size and expected growth of our market may prove to be inaccurate. Even if the market in which we compete 
meets our size estimates and forecasted growth, our business could fail to grow at similar rates. 

Risks Related to Reimbursement 

If we are unable to expand, maintain or obtain third-party payer coverage and reimbursement for Panorama, Horizon 
and our other tests, or if we are required to refund any reimbursements already received, our revenues and results of 
operations would be adversely affected. 

Our  business  depends  on  our  ability  to  obtain  and  maintain  adequate  coverage  and  reimbursement  from 
third-party payers and patients. Third-party reimbursement for our testing represents a significant portion of our revenues, 
and we expect third-party payers such as insurance companies and government healthcare programs to continue to be our 
most significant source of payments. In particular, we believe that the following will be necessary for us to continue to 
achieve commercial success: continued expansion of insurance coverage from the high-risk to the average-risk pregnancy 
population, which represents roughly 80% of the United States pregnancy market, and for microdeletions screening, and 
obtaining positive coverage determinations and favorable reimbursement rates from commercial third-party payers, the 
Centers for Medicare & Medicaid, or CMS, and state reimbursement programs for our tests. As discussed in the risk factor 
entitled  “—Uncertainty  in  the  development  and  commercialization  of  our  enhanced  or  new  tests  or  services  could 
materially adversely affect our business, financial condition and results of operations”, we expect to publish data from 
our SMART Study in 2021. Historically, we have not received reimbursement for a significant number of Panorama tests 
that we have performed for average-risk patients and for microdeletions; we have recently released positive key results 
from our SMART Study, but we cannot be certain whether, or to what extent, the SMART Study may impact insurance 
coverage and reimbursement for Panorama in the average-risk population or for microdeletions. In addition, while we have 
received a positive local coverage determination from the Molecular Diagnostic Services Program, which identifies and 
establishes Medicare coverage and reimbursement for molecular diagnostic tests, to provide Medicare benefits for serial 
use  of  our  Signatera  test  in  patients  with  Stage II  or  III  colorectal  cancer,  we  cannot  guarantee  that  our  test  will  be 
reimbursed at the rate we expect. Furthermore, while we have also received a positive coverage decision for our Prospera 
test, we cannot guarantee that our test will continue to be reimbursed at the same or a similar rate as we have received thus 
far. If we are unable to obtain or maintain coverage or adequate reimbursement from, or achieve in-network status with, 
third-party payers for our existing or future tests, our ability to generate revenues will be limited. For example, physicians 
may be reluctant to order our tests due to the potential of a substantial cost to the patient if reimbursement coverage is 
unavailable or insufficient. 

48 

In making coverage determinations, third-party payers often rely on practice guidelines issued by professional 
societies.  The  practice  guidelines  issued  by  professional  societies  now  generally  acknowledge  that  NIPT  is  the  most 
sensitive screening option for, and/or are generally supportive of NIPT in, average-risk pregnancies, in addition to high-risk 
pregnancies. However, the latest of such practice bulletins, issued by the American College of Obstetrics and Gynecology 
and supported by the Society for Maternal-Fetal Medicine, or SMFM, was very recent, and while many third-party payers 
now  reimburse  for NIPT  for average-risk patients,  it remains  the  case  that  not  all  third-party payers, particularly  state 
Medicaid payers, do so. In addition, SMFM’s position with respect to microdeletions remains that routine screening for 
microdeletions should not be performed. Many third-party payers do not reimburse for microdeletions screening. While 
we have published data on the performance of Panorama for the 22q11.2 deletion syndrome, we have and may continue 
to experience low reimbursement rates for Panorama for microdeletions. If we are unable to publish satisfactory additional 
data on the performance of Panorama for 22q11.2 deletion syndrome, including data from our SMART Study, we may be 
unable  to  obtain  positive  coverage  determinations  for  our  test.  If  third-party  payers  do  not  reimburse  for  NIPT  for 
average-risk pregnancies or microdeletions in the future, our future revenues and results of operations would be adversely 
affected, particularly to the extent that we continue to perform large volumes of tests for which third-party payors do not 
reimburse. 

In  addition,  a  CPT  code  for  microdeletions  took  effect  in  January  2017.  We  have  experienced  low  average 
reimbursement  rates  for  microdeletions  under  this  code,  and  we  expect  that  this  code  will  continue  to  cause  our 
microdeletions reimbursement to remain low, at least in the near term, due to third-party payers declining to reimburse 
and as a result of reduced reimbursement, under the code, which has had, and we expect to continue to have, an adverse 
effect on our revenues. Also, a new CPT code for expanded carrier screening tests took effect in January 2019. The new 
code has caused and may continue to cause reimbursement rates for our broader Horizon carrier screening panel to decrease 
because those tests may be reimbursed as a combined single panel instead of as multiple individual tests. 

The reimbursement environment, particularly for molecular diagnostics, is continually changing and our efforts 
to broaden reimbursement for our tests with third-party payers may not be successful. Third-party payers from whom we 
have received reimbursement may withdraw coverage or decrease the amount of reimbursement for our tests at any time 
and  for  any  reason.  In  some  cases,  our  tests  or  their  uses  within  certain  populations,  such  as  for  microdeletions,  are 
considered experimental by third-party payers and, as a result, some payers have decided not to cover or reimburse for 
such tests. In addition, some third-party payers bundle payment for multiple tests or tests that screen for multiple conditions, 
such as our Horizon test or our Panorama test and the separate Panorama screen for microdeletions, into a single payment 
rate, thereby limiting our reimbursement in those situations. Payers may also dispute our billing or coding. Based on any 
of the foregoing, third-party payers may also decide to deny payment or recoup payment for testing that they contend to 
have been not medically necessary, against their coverage determinations, or for which they have otherwise overpaid, and 
we may be required to refund reimbursements already received. We deal with requests for recoupment from third-party 
payers from time to time in the ordinary course of our business, and it is likely that we will continue to do so in the future. 
See “Note 8—Commitments and Contingencies—Third-Party Payer Reimbursement Audits” in the Notes to Consolidated 
Financial Statements. If a third-party payer denies payment for testing, reimbursement revenue for our testing could decline. 
If a third-party payer successfully proves that payment for prior testing was in breach of contract or otherwise contrary to 
law, they may recoup payment, which amounts could be significant and would impact our results of operations, and it may 
decrease reimbursement going forward. We may also decide to negotiate and settle with a third-party payer in order to 
resolve an allegation of overpayment. Any of these outcomes might require us to restate our financials from a prior period, 
which would likely cause our stock price to decline. For example, in 2018 we reached a settlement with certain government 
payers regarding past reimbursement submissions; although the settlement involved no admission of fault by us and no 
corporate integrity agreement, we cannot guarantee that we will not be subject to similar claims, resulting in additional 
settlements or repayments, in the future. 

Furthermore,  some  of  our  contracts  with  third-party  payers  contain  so-called  most  favored  nation  provisions, 
pursuant to which we have agreed that we will not bill the third-party payer more than we bill any other third-party payer. 
We  must  therefore  monitor  our  billing  and  claims  submissions  to  ensure  that  we  remain  in  compliance  with  these 
contractual requirements with third-party payers. If we do not successfully manage these most favored nation provisions, 
we may need to forego revenues from some third-party payers or reduce the amount we bill to each third-party payor with 
a most-favored nation clause in its contract that is violated, which would adversely affect our revenues. This situation 
could also subject us to claims for recoupment, which could require the time and attention of our management, require the 

49 

expense of engaging outside counsel or consultants, and may be a distraction from development of our business, adversely 
impacting  our  operations.  Such  recoupment  demands  could  also  ultimately  result  in  an  obligation  to  repay  amounts 
previously earned. 

In addition, if a third-party payer denies coverage, it may be difficult for us to collect from the patient, and we 
may not be successful in doing so. In particular, we are often unable to collect the full amount of a patient’s responsibility 
where we are an out-of-network provider and the patient is left with a large balance, despite our good faith efforts to collect. 
As a result, we cannot always collect the full amount due for our tests when third-party payers deny coverage, cover only 
a portion of the invoiced amount or the patient has a large deductible, which may cause payers to raise questions regarding 
our billing policies and patient collection practices. We believe that our billing policies and our patient collection practices 
are compliant with applicable laws. However, we have in the past received, and we may in the future receive, inquiries 
from third-party payers regarding our billing policies and collection practices. While we have addressed these inquiries as 
and when they have arisen, there is no guarantee that we will always be successful in addressing such concerns in the 
future, which may result in a third-party payer deciding to reimburse for our tests at a lower rate or not at all, seeking 
recoupment of amounts previously paid to us, or bringing legal action to seek reimbursement of previous amounts paid. 
Any of such occurrences could cause reimbursement revenue for our testing, which constitutes the large majority of our 
revenue, to decline. Additionally, if we were required to make a repayment, such repayment could be significant, which 
would impact our results of operations, and we might be required to restate our financials from a prior period, which would 
likely cause our stock price to decline. 

We  are  aware  of  policies  and  practices  of  our  competitors  to  offer  patients  a  set  cap  on  their  out-of-pocket 
responsibility, waive patient responsibility altogether, and, in some cases, to not send patients a bill at all, all of which we 
believe is not in accordance with third-party payers’ policies and, in many cases, not compliant with the law. In contrast, 
it  is  our  policy  not  to  offer  such  caps  or  waivers  and  to  send  bills  to  patients  for  services  rendered.  Because  of  this 
discrepancy, our offerings may be perceived as less attractive to patients and their healthcare providers, who are concerned 
about patients having a large financial responsibility for these products. As a result, we believe that our revenues and 
results of operations have been adversely affected, and may continue to be so affected to the extent that our competitors 
continue such practices. 

Our  revenues  may  be  adversely  affected  if  we  are  unable  to  successfully  obtain  reimbursement  from  the  Medicare 
program and state Medicaid programs. 

Our revenues from Medicare are currently relatively small, given the population that Medicare covers and the 
fact that our testing in women’s health, which has comprised the significant majority of our business, generally is not 
received by Medicare beneficiaries. As a result, we do not expect our Medicare revenues to change materially with regard 
to NIPT. However, Medicare reimbursement impacts our revenues in our oncology and organ health business, as a large 
proportion of these patients are covered by Medicare. Furthermore, Medicare reimbursement can affect both Medicaid 
reimbursement,  which  is  relevant  to  NIPT,  and  reimbursement  from  commercial  third-party  payers.  Specifically, 
fee-for-service Medicaid programs generally do not reimburse at rates that exceed Medicare’s fee-for-service rates, and 
many commercial third-party payers set their payment rates at a percentage of the amounts that Medicare pays for testing 
services. Medicare reimbursement rates are typically based on the Clinical Laboratory Fee Schedule, or CLFS, set by CMS. 
Our current Medicare Part B reimbursement for Panorama was not set pursuant to a national coverage determination by 
CMS.  Although  we  believe  that  coverage  is  available  under  Medicare  Part B  even  without  such  a  determination,  we 
currently lack the certainty afforded by a formal national coverage determination by CMS. Thus, CMS could issue an 
adverse coverage determination as to Panorama which could influence other third-party payers, including Medicaid, and 
could have an adverse effect on our revenues. 

It is estimated that nearly half of all births in the United States are to state Medicaid program recipients. Each 
state’s Medicaid program has its own coverage determinations related to our testing, and many state Medicaid programs 
do not provide their recipients with coverage for our testing. Even if our testing is covered by a state Medicaid program, 
we must be recognized as a Medicaid provider by the state in which the Medicaid recipient receiving the services resides 
in order for us to be reimbursed by a state’s Medicaid program, including under a Medicaid managed care plan. Our San 
Carlos  laboratory  is  currently  recognized  by  48  states  as  a  Medicaid  provider,  and  we  are  currently  in  the  process  of 
obtaining recognition of our Austin laboratory as a Medicaid provider in states in which the Austin laboratory is not already 

50 

credentialed; however, even if we are recognized as a Medicaid provider in a state, if Medicare’s CLFS rate for our services 
and tests are low, the Medicaid reimbursement amounts are sometimes as low, or lower, than the Medicare reimbursement 
rate. In addition, from time to time we receive requests from state Medicaid programs seeking information or documents 
to determine  eligibility  for  and  the  amount  of Medicaid  reimbursement.  As  a  result of  all  of  these  factors,  many  state 
Medicaid programs only reimburse our testing at a very low dollar amount, or not at all. Low or zero-dollar Medicaid 
reimbursement rates for our tests could have an adverse effect on our business and revenues. 

Our  revenues  may  be  adversely  impacted  if  third-party  payers  withdraw  coverage  or  provide  lower  levels  of 
reimbursement due to changing policies, billing complexities or other factors. 

We are in network, or under contract, with the significant majority of third-party payers from whom we receive 
reimbursement; this means that we have agreements with most third-party payers that govern approval or payment terms. 
However, these contracts do not guarantee reimbursement for all testing we perform. For example, many third-party payers 
with whom we have written agreements have policies that state they will not reimburse for the screening of microdeletions, 
or don’t have a policy in place to reimburse for microdeletions screening. In addition, the terms of certain of our agreements 
require a physician or qualified practitioner’s signature on test requisitions or require other controls and procedures prior 
to conducting a test. In particular, third-party payers have increasingly required prior authorization to be obtained prior to 
conducting a test, as a condition to reimbursing for the test. This has placed a burden on our billing operations as we have 
to dedicate or source resources to ensuring that these requirements are met and to conduct follow-up and address issues as 
they arise, and has also impacted our results of operations, including our gross margins, since the fourth quarter of 2017, 
when these requirements began to take effect. To the extent we or the physicians ordering our tests do not follow the prior 
authorization requirements, we may be subject to claims for recoupment of reimbursement amounts previously paid to us, 
or may not receive some or all of the reimbursement payments to which we would otherwise be entitled. This has occurred 
in some cases and may occur more frequently in the future, which does and would have an adverse impact on our revenues. 

Where we are considered to be an out of network provider, which is the case with some third-party payers from 
whom we receive reimbursement, such third-party payers could withdraw coverage and decline to reimburse for our tests 
in the future, for any reason. Managing reimbursement on a case-by-case basis is time-consuming and contributes to an 
increase in the number of days it takes us to collect on accounts, which also increases our risk of non-payment. Negotiating 
reimbursement on a case-by-case basis also typically results in the receipt of reimbursement at a significant discount to 
the list price of our tests. 

Even if we are being reimbursed for our tests, third-party payers may review and adjust the rate of reimbursement, 
require co-payments from patients or stop paying for our tests. Government healthcare programs and other third-party 
payers continue to increase their efforts to control the cost, utilization and delivery of healthcare services by demanding 
price  discounts  or  rebates  and  limiting  coverage  of,  and  amounts  they  will  pay  for,  molecular  diagnostic  tests.  These 
measures have resulted in reduced payment rates and decreased utilization in the clinical laboratory industry. Because of 
these  cost-containment  measures,  governmental  and  commercial  third-party  payers  may  reduce,  suspend,  revoke  or 
discontinue  payments  or  coverage  at  any  time,  including  payors  that  currently  provide  reimbursement  for  our  tests. 
Reduced reimbursement of our tests may harm our business, financial condition or results of operations. 

Billing for clinical laboratory testing services is complex. We perform tests in advance of payment and without 
certainty as  to  the outcome of  the  billing process.  In  cases  where we  expect  to receive  a fixed fee per  test due  to our 
reimbursement  arrangements,  we  may  nevertheless  encounter  disputes  over  pricing  and  billing.  Among  the  factors 
complicating our billing of third-party payers are disparity in coverage among various payers; disparity in, and increasingly 
difficult, information and billing requirements among payers, including with respect to prior authorization requirements 
and procedures and establishing medical necessity; and incorrect or missing billing information, which is required to be 
provided by the ordering healthcare practitioner. These billing complexities, and the associated uncertainty in obtaining 
payment  for  our  tests,  could  result  in  reduced  reimbursement  of  our  tests,  which  could  harm  our  business,  financial 
condition and results of operations. 

In the United States, the AMA generally assigns specific billing codes for laboratory tests under a coding system 
known as Current Procedure Terminology, or CPT, which we and our ordering healthcare providers must use to bill and 
receive reimbursement for our diagnostic tests. Once the CPT code is established by the AMA, CMS establishes payment 
levels and coverage rules under Medicare while private payers independently establish rates and coverage rules. A CPT 

51 

code specific to NIPT for aneuploidies, and a CPT code for microdeletions, are in place, and CMS has established a pricing 
benchmark for aneuploidy and microdeletions testing. However, our microdeletions reimbursement has decreased since 
the implementation of the microdeletions CPT code because third-party payers are declining to reimburse under this code 
or reimbursing at a much lower rate than we had previously received. Furthermore, we cannot guarantee that we will be 
able  to  negotiate  favorable  rates  for  this  code  or  receive  reimbursement  at  all  if  we  are  unable  to  collect  and  publish 
additional data, including the expected publications from our SMART Study, and obtain positive coverage determinations 
for Panorama for microdeletions. In addition, a CPT code for expanded carrier screening tests has been implemented, 
which  has  caused  and  may  continue  to  cause  reimbursement rates for our Horizon  expanded  carrier  screening  tests  to 
decline. We do not currently have assay-specific CPT codes assigned for all of our tests, and there is a risk that we may 
not be able to obtain such codes or, if obtained, we may not be able to negotiate favorable rates for such codes. We currently 
submit for reimbursement using CPT codes based on the guidance of outside coding experts and legal counsel. There is a 
risk that the codes we currently submit may be rejected or withdrawn or that third-party payers will seek refunds of amounts 
that they claim were inappropriately billed based on either the CPT code used, or the number of units billed. In addition, 
third-party payers may not establish positive coverage policies for our tests or adequately reimburse for any CPT code we 
may use, or seek recoupment for testing previously performed, which have occurred in the past. 

Regulatory and Compliance Risks  

We may be subject to increased compliance risks as a result of our rapid growth, including our dependence on our 
sales, marketing and billing efforts. 

Approximately 87% and 80% of our total revenues for the years ended December 31, 2020 and 2019, respectively, 
were attributable to our U.S. direct sales. We have had to expand our training and compliance efforts in line with our 
increasing reliance on personnel in our sales, marketing and billing functions, and our expansion of these functions in line 
with the overall growth in our business. We continue to monitor our personnel, but we have in the past experienced, and 
may in the future experience, situations in which employees fail to strictly adhere to our policies. In addition, sales and 
marketing activities in the healthcare space are subject to various rules and regulations, as described in the risk factor 
entitled “Reimbursement and Regulatory Risks Related to Our Business—If we or our laboratory distribution partners, 
consultants or commercial partners act in a manner that violates healthcare fraud and abuse laws or otherwise engage in 
misconduct,  we  may be  subject  to  civil  or criminal  penalties;”  moreover, our billing  and  marketing messaging  can be 
complex and nuanced, and there may be errors or misunderstandings in our employees’ communication of such messaging. 
Furthermore, we utilize text messaging, email, phone calls and other similar methods to communicate with patients who 
are  existing  or  potential  users  of  our  products  for  various  business  purposes.  These  activities  subject  us  to  laws  and 
regulations  relating  to  communications  with  consumers,  such  as  the  CAN-SPAM  Act  and  the  Telephone  Consumer 
Protection Act, violations of which could subject us to claims by consumers, who may seek actual or statutory damages, 
which could be material in the aggregate, as has happened in the past, as described further in “Note 8—Commitments and 
Contingencies—Legal Proceedings” in the Notes to Consolidated Financial Statements. As we continue to scale up our 
sales  and  marketing  efforts  in  line  with  the  rapid  growth  in  our  business,  in  particular  our  increased  pace  of  product 
launches  as  well  as  further  geographical  expansion,  we  will  continue  to  face  an  increased  need  to  remain  vigilant  in 
monitoring and improving our policies, processes and procedures to maintain compliance with a growing number and 
variety of laws and regulations, including with respect to consumer marketing. To the extent that there is any violation, 
whether actual, perceived or alleged, of our policies or applicable laws and regulations, we may incur additional training 
and compliance costs, may receive inquiries from third-party payers or other third parties, or be held liable or otherwise 
responsible  for  such  acts  of  non-compliance.  Any of  the  foregoing  could  adversely  affect  our  cash flow  and  financial 
condition. 

If the FDA were to begin actively regulating our tests, we could incur substantial costs and delays associated with trying 
to obtain premarket clearance or approval and incur costs associated with complying with post-market controls. 

We currently offer a number of genetic tests, and each of those tests is an LDT. The FDA considers an LDT to 
be a test that is designed, developed, validated and used within a single laboratory. The FDA has historically taken the 
position that it has the authority to regulate such tests as medical devices under the FDC Act, but it has generally exercised 
enforcement  discretion with regard  to LDTs.  This means  that  even  though  the FDA believes  it  can  impose regulatory 

52 

requirements on LDTs, such as requirements to obtain premarket approval or clearance of LDTs, it has generally chosen 
not to enforce those requirements to date. 

The FDA has previously laid out elements of a potential LDT regulatory framework but has not established any 
regulatory  requirements.  In  August  2020,  the  United  States  Department  of  Health  and  Human  Services,  or  HHS, 
announced  that  FDA  will  no  longer  require  premarket  review  of  LDTs  absent  notice-and-comment  rulemaking.  HHS 
rescinded  all  guidance  documents  and  informal  statements  of  policy  concerning  LDTs.  The  FDA’s  activities  around 
regulating  LDTs  had  prompted  the  drafting  of  legislation  governing  diagnostic  products  and  services  that  sought  to 
substantially revamp the regulation of both LDTs and IVDs. Congress may still act to provide further direction on the 
regulation of LDTs and substantially modify the regulation of IVDs. The change of Administration in January 2021 could 
result in a change in HHS policy with respect to LDTs, which could lead to more active FDA regulation of our tests. 

In the meantime, the regulation by the FDA of LDTs remains uncertain. If FDA premarket clearance, approval 
or authorization is required for any of our existing or future tests, or for any components or materials we use in tests, we 
may be forced to stop selling our tests or we may be required to modify claims for or make other changes to our tests while 
we or our supplier work to obtain FDA clearance, approval or de novo authorization. Our business would be adversely 
affected  while  such  review  is  ongoing  and  if  we  or  our  supplier  are  ultimately  unable  to  obtain  premarket  clearance, 
approval or de novo authorization. For example, the regulatory premarket clearance, approval or de novo authorization 
process may involve, among other things, successfully completing analytical, pre-clinical and/or clinical studies beyond 
the  studies  we  have  already  performed  or  plan  to  perform  for  each  of  our  products  and  would  involve  submitting  a 
premarket notification, or 510(k), a de novo application, or filing a PMA application with the FDA. As further described 
in the risk factor entitled “Uncertainty in the development and commercialization of our enhanced or new tests or services 
could materially adversely affect our business, financial condition and results of operations,” completing such studies 
requires the expenditure of time, attention and financial and other resources, and may not yield the desired results, which 
may  delay,  limit  or  prevent  regulatory  clearances,  approvals  or  de  novo  authorizations.  In  addition,  we  may  require 
cooperation in our filings for FDA clearance, approval or de novo authorization from third-party manufacturers of the 
components of our tests. If we are unable to obtain such required cooperation, we may be unable to achieve the desired 
regulatory clearances, approvals or de novo authorizations, or may be delayed or be required to expend additional costs 
and other resources in doing so. For example, Illumina currently is our sole sequencer and sequencing reagent supplier. If 
we seek to achieve regulatory clearance, approval or de novo authorization for Panorama, to the extent that Panorama 
incorporates Illumina’s sequencer or sequencing reagents, we may require Illumina’s cooperation in the regulatory process. 
We may face difficulty obtaining cooperation from Illumina because Illumina is the parent company of Verinata, a direct 
competitor of ours in the NIPT field. In addition, we have been party to certain intellectual property proceedings with 
Illumina as described in “Note 8—Commitments and Contingencies—Legal Proceedings” in the Notes to Consolidated 
Financial Statements. Furthermore, if FDA premarket clearance, approval or de novo authorization is required, our cash 
flows may be adversely affected until we obtain such clearance, approval or de novo authorization, as most third-party 
payers, including Medicaid, will not reimburse for use of medical devices which are required to, but which do not, have 
marketing authorization. 

In May 2019, the FDA granted Breakthrough Device designation for our Signatera test for use in the post-surgical 
detection and quantification of ctDNA in the blood of patients previously diagnosed with certain types of cancer and in 
combination with certain drugs, which enables us to have increased interactions with FDA. We cannot assure you that this 
designation will lead to accelerated review or approval of our regulatory submissions for Signatera. 

We cannot assure you that Panorama or any of our other tests for which we decide to pursue or are required to 
obtain premarket clearance, approval or de novo authorization by the FDA will be cleared, approved or authorized on a 
timely basis, if at all. In addition, if a test has been cleared, approved or authorized, certain kinds of changes that we may 
make to improve the test, or as a result of issues with suppliers of the components of the test or if a supplier modifies its 
component upon which our approval relies, may need to be cleared, approved or authorized by the FDA before we can 
implement  them,  which  could  increase  the  time  and  expense  involved  in  implementing  such  changes  commercially. 
Ongoing compliance with FDA regulations would increase the cost of conducting our business and subject us to heightened 
regulation by the FDA and penalties for failure to comply with these requirements, any of which may adversely impact 
our business and results of operations. 

53 

Furthermore, the FDA or the Federal Trade Commission, or FTC, may object to the materials and methods we 
use to promote the use of our current tests or other LDTs we may develop in the future, including with respect to the 
product claims in our promotional materials, and may initiate enforcement actions against us. Enforcement actions by the 
FDA may include, among others, untitled or warning letters; fines; injunctions; civil or criminal penalties; recall or seizure 
of current or future tests, products or services; operating restrictions and partial suspension or total shutdown of production. 
Enforcement actions by the FTC may include, among others, injunctions, civil penalties, and equitable monetary relief. 

Failure  to  obtain  necessary  regulatory  approvals  may  adversely  affect  our  ability  to  expand  our  operations 
internationally, including our ability to continue commercializing our cloud-based distribution model. 

An important part of our business strategy is to expand and offer our tests internationally, either by providing our 
testing services directly or through our laboratory partners, or through our licensees under our Constellation cloud-based 
distribution model. As we do so, we will become increasingly subject to or impacted by the regulatory requirements of 
foreign jurisdictions, which are varied and complex. Our tests, and certain components of our tests, may be subject to the 
regulatory approval requirements in each foreign country in which they are sold by us or a laboratory partner, or by our 
licensees under our cloud-based distribution model, and our future performance would depend on us or our partners or 
licensees obtaining any necessary regulatory approvals in a timely manner. For example, while we have entered into a 
license agreement with BGI Genomics to commercialize our Signatera test in China and to develop reproductive health 
tests  in  select  markets  using  BGI  Genomics’s  sequencing  instruments  and  platform,  such  commercialization  and 
development  activities  will  be  subject  to  obtaining  and  maintaining  necessary  regulatory  approvals  in  the  relevant 
jurisdictions.  In  addition,  while  we  have  obtained  a  CE  Mark  from  the  European  Commission  for  our  Constellation 
software and the key reagents required for our licensees to run their NIPT based on our technology, we have not obtained 
a CE Mark for our Panorama test as a whole. Therefore, while we are able to offer Constellation in the European Union 
and other countries that accept a CE Mark, we are unable to offer Panorama as an IVD directly in these jurisdictions. This, 
coupled with our use of our Panorama brand name under our Constellation model, has caused regulatory authorities to 
question whether we, our laboratory partners or our licensees may be marketing, commercializing or otherwise offering 
our  tests  without  required  approvals.  We  are  occasionally  required  to  address  inquiries  from  regulatory  authorities  in 
various countries, such as those in the European Union, regarding the regulatory status of our Panorama or Constellation 
offerings, and expect that we will continue to face similar inquiries. If we do not continue to satisfactorily address any 
such questions in the future, we may be required to cease offering our products, either directly or through our partners or 
licensees, in the relevant country. This may in turn result in similar concerns, and subsequent cessation of our sources of 
revenue, in other countries. 

We may also be at a competitive disadvantage in the European Union to our competitors who have obtained a 
CE  Mark  for  their  end  to  end NIPT.  In  addition,  as  further described  in  the risk  factor  entitled  “Risks  Related  to Our 
Business and Industry—We rely on a limited number of suppliers or, in some cases, single suppliers, for some of our 
laboratory instruments and materials and may not be able to find replacements or immediately transition to alternative 
suppliers,” blood collection tubes sourced solely from Streck are required to run our tests. These blood collection tubes 
are CE Marked by the European Commission; however, if such blood collection tubes are not registered in jurisdictions 
that do not accept a CE Mark, we may be unable to expand our business in such jurisdictions. 

We may also need to obtain regulatory clearance, approval or de novo authorization in the United States for our 
Constellation  software  in  order  for  it  to  be  used  by  third  parties  in  the  development  and  commercialization  of  their 
diagnostic  tests  based  on  our  technology.  We  have  discussed  with  the  FDA  the  regulatory  status  of  a  portion  of  our 
Constellation software, the copy number calculator, or CNC, to make calls of copy number variants, which are genetic 
mutations in which relatively large regions of the genome have been deleted or duplicated. The FDA has indicated that 
the  CNC  may  be  appropriate  for  review  under  the  de  novo  classification  process,  which  is  less  burdensome  than  the 
premarket approval, or PMA, process. The FDA stated that it would not prevent us from marketing Constellation in the 
United States while we discuss with the FDA how it will be regulated; however, it is possible that the FDA may reverse 
itself either on the appropriate regulatory review path or on the issue of our ability to continue to market Constellation. In 
addition, the 21st Century Cures Act, enacted in 2016, included a number of changes to the FDA’s regulatory approach to 
software that may have bearing on the regulatory status of our Constellation software. We cannot guarantee that we will 
be able to obtain such clearance, approval or authorization for our Constellation software, in the event that we are required 
to do so. If we are unable to do so, we would be unable to commercialize our cloud-based distribution model in the United 

54 

States. If we are able to do so, we will be subject to ongoing FDA obligations and continued regulatory oversight and 
review, including compliance with requirements such as the quality system regulation, or QSR, which establishes extensive 
requirements for quality assurance and control as well as manufacturing procedures; the listing of our devices with the 
FDA;  adverse  event  and  malfunction  reporting;  corrections  and  removals  reporting;  and  labeling  and  promotional 
requirements.  We  may  also  be  subject  to  additional  FDA  post-marketing  obligations.  If  we  are  not  able  to  maintain 
regulatory compliance to the extent required, we may not be permitted to offer our Constellation software and may be 
subject to enforcement action by the FDA, such as the issuance of warning or untitled letters, fines, injunctions and civil 
penalties; recall or seizure of products; operating restrictions and criminal prosecution. 

Regulatory  approval  can  be  a  lengthy,  expensive  and  uncertain  process.  In  addition,  regulatory  processes  are 
subject to change, and new or changed regulations can result in unanticipated delays and cost increases. For example, the 
European  Commission  has  adopted  revised  in-vitro  diagnostic  regulations,  or  IVDR,  which  are  expected  to  become 
effective in 2022. Among others, the new regulations introduce risk-based classification for IVDs and will require notified 
body  involvement  for various  classes  of  devices,  including  reproductive health  tests  such  as  Panorama,  which will  be 
classified as a Class C product. As such, we will also be required to submit clinical evidence and post-market performance 
data to regulators. We or our partners or licensees may not be able to obtain regulatory approvals on a timely basis, if at 
all, which may cause us to incur additional costs or prevent us from marketing our tests in the United States or in foreign 
countries. 

Changes in laws and regulations, or in their application, may adversely affect our business, financial condition and 
results of operations. 

The  clinical  laboratory  testing  industry  is  highly  regulated,  and  failure  to  comply  with  applicable  regulatory, 
supervisory, accreditation, registration or licensing requirements may adversely affect our business, financial condition 
and results of operations. In particular, the laws and regulations governing the marketing and research of clinical diagnostic 
testing are extremely complex and in many instances there are no clear regulatory or judicial interpretations of these laws 
and regulations, increasing the risk that we may be found to be in violation of these laws. 

Furthermore, the molecular diagnostics industry as a whole is a growing industry and regulatory bodies such as 
HHS or the FDA may apply heightened scrutiny to new developments in the field. While we have taken steps to ensure 
compliance with the current regulatory regime in all material respects, given its nature and our geographical diversity, 
there could be areas where we are non-compliant. Any change in the federal or state laws or regulations relating to our 
business may require us to implement changes to our business or practices, and we may not be able to do so in a timely or 
cost-effective manner. Should we be found to be non-compliant with current or future regulatory requirements, we may 
be subject to sanctions which could include changes to our operations, adverse publicity, substantial financial penalties 
and  criminal  proceedings,  which  may  adversely  affect  our  business,  financial  condition  and  results  of  operations  by 
increasing our cost of compliance or limiting our ability to develop, market and commercialize our tests. 

In addition, there has been a recent trend of increased U.S. federal and state regulation, scrutiny and enforcement 
relating to payments made to referral sources, which are governed by laws and regulations including the Stark law, the 
federal Anti-Kickback Statute, the federal False Claims Act, and EKRA as well as state equivalents of such laws. Among 
other requirements, the Stark law requires laboratories to track, and places a cap on, non-monetary compensation provided 
to referring physicians. 

While  we  have  a  compliance  plan  to  address  compliance  with  government  laws  and  regulations,  including 
applicable  fraud  and  abuse  laws  and  regulations  such  as  those  described  in  this  risk  factor,  the  evolving  commercial 
compliance environment and the need to build and maintain robust and scalable systems to comply with regulations in 
multiple  jurisdictions  with  different  compliance  and  reporting  requirements  increases  the  possibility  that  we  could 
inadvertently violate one or more of these requirements. 

55 

If we fail to comply with federal, state and foreign laboratory licensing requirements, we could lose the ability to perform 
our tests or experience disruptions to our business. 

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 or 
impairment of, or assessment of the health of, human beings. CLIA regulations require clinical laboratories to obtain a 
certificate  and  mandate  specific  standards  in  the  areas  of  personnel  qualifications,  administration,  participation  in 
proficiency testing, patient test management and quality assurance. CLIA certification is also required in order for us to 
be  eligible  to bill  state  and  federal healthcare programs,  as  well  as many private  third-party payers, for our  tests. Our 
laboratories located in Austin, Texas and San Carlos, California are both CLIA certified and accredited by the College of 
American Pathologists, or CAP, a third party accreditation organization under deemed, or recognized, authority by CMS. 
To  renew  these  certifications,  we  are  subject  to  survey  and  inspection  every  two  years.  Moreover,  CLIA  and/or  state 
inspectors may conduct random inspections of our clinical laboratory or conduct an inspection as a result of a complaint 
or reported incident, as has occurred. Any failure to address identified deficiencies, or to otherwise comply with CLIA, 
CAP or state requirements, can result in enforcement actions, including the revocation, suspension, or limitation of our 
CLIA and/or CAP certificate of accreditation or state laboratory permit, as well as a directed plan of correction, on-site 
monitoring, civil monetary penalties, civil actions for injunctive relief, criminal penalties, suspension or exclusion from 
the Medicare and Medicaid programs and significant adverse publicity. Bringing our laboratory back into compliance with 
CLIA  requirements  could  cause  us  to  incur  significant  expenses  and  potentially  lose  revenues  in  order  to  address 
deficiencies and achieve compliance. 

Some states require that we hold licenses or permits to test samples from patients in those states, even if our 
laboratory facilities are not located in those states, and as a result we are also required to maintain standards related to 
those states’ licensure requirements to conduct testing in our laboratories. California state laboratory laws and regulations 
establish standards for the operation of our clinical laboratory and performance of test services in San Carlos, California 
as well as in our Austin, Texas laboratory, because our Texas laboratory receives specimens originating from California; 
the State of Texas implements CLIA requirements on laboratories operating within Texas but does not impose additional 
state licensure or registration requirements. Additionally, all  personnel involved in testing in our California laboratory 
must maintain a California state license or be supervised by licensed personnel. We maintain a license in good standing 
with the California Department of Public Health, or CDPH, for both our California and Texas laboratories. In addition, 
because we test specimens originating from New York at our San Carlos, California laboratory, we have been required to 
obtain a state laboratory permit for our San Carlos laboratory from the New York State Department of Health, or NYSDOH. 
We do not test specimens originating from New York at our Texas laboratory. NYSDOH requires out-of-state laboratories 
that test specimens originating from New York to hold an NYSDOH permit and to comply with NYSDOH laboratory 
standards, including prior NYSDOH approval of LDTs. Our San Carlos clinical laboratory has received approval from the 
NYSDOH to offer our Panorama, Horizon, Spectrum, Anora, Prospera and non-invasive prenatal paternity LDTs. The 
laboratory director must also maintain a Certificate of Qualification issued by NYSDOH. As under CLIA, we are subject 
to routine on-site inspections or inspections in response to a complaint under both California and New York state laboratory 
laws and regulations. If we are found to be out of compliance with either California or New York requirements, CDPH or 
NYSDOH may suspend, restrict or revoke our license or laboratory permit, respectively (and, with respect to California, 
may exclude persons or entities from owning, operating or directing a laboratory for two years following such license 
revocation), assess civil monetary penalties, or impose specific corrective action plans, among other sanctions. We cannot 
assure you that the regulators in any state from which we have obtained a required license or permit will at all times find 
us  to  be  in  compliance  with  the  applicable  laws  of  their  respective  state,  which  may  result  in  suspension,  limitation, 
revocation or annulment of our laboratory’s license for that state or negative impact to our CLIA certificate, censure, or 
civil monetary penalties, and would result in our inability to test samples from patients in that state. Any such consequences 
could materially and adversely affect our business by prohibiting or limiting our ability to offer testing. 

Changes in government healthcare policy could increase our costs and negatively impact coverage and reimbursement 
for our tests by governmental and other third-party payers. 

The U.S. government has shown significant interest in pursuing healthcare reform and reducing healthcare costs. 
Government healthcare policy has been and will likely continue to be a topic of extensive legislative and executive activity 
in the U.S. federal government and many U.S. state governments. As a result, our business could be affected by potentially 

56 

significant  and  unanticipated  changes  in  government  healthcare  policy,  such  as  changes  in  reimbursement  levels  by 
government  third-party  payers.  Any  such  changes  could  substantially  impact  our  revenues,  increase  costs  and  divert 
management attention from our business strategy. We cannot predict the impact, if any, of governmental healthcare policy 
changes on our business, financial condition and results of operations. 

In the United States, the Patient Protection and Affordable Care Act, as amended by the Healthcare and Education 
Reconciliation Act of 2010, or collectively, the PPACA, was signed into law in March 2010 and significantly impacted 
the U.S. pharmaceutical and medical device industries, including the diagnostics sector, in a number of ways. Among other 
things, the PPACA expanded healthcare fraud and abuse laws such as the False Claims Act and the Anti-Kickback Statute, 
including but not limited to required disclosures of financial arrangements with physician customers, required reporting 
of  discovered  overpayments,  lower  thresholds  for  violations,  new  government  investigative  powers,  and  enhanced 
penalties  for  such  violations.  The  PPACA  restricts  insurers  from  charging  higher  premiums  or  denying  coverage  to 
individuals with pre-existing conditions, and requires insurers to cover certain preventative services without charging any 
copayment or coinsurance, including screening for lung, breast, colorectal and cervical cancers. However, there have been 
multiple  attempts  to  repeal  PPACA  or  significantly  scale  back  its  applicability,  which  could  negatively  impact 
reimbursement for our testing. This could adversely affect our test volumes and, in turn, our business, financial condition, 
results  of  operations,  and  cash  flows.  For  example,  the  Tax  Cuts  and  Jobs  Act  of  2017,  or  the  Tax  Act,  repeals  the 
requirement under PPACA that consumers buy insurance or pay a penalty unless they qualified for an applicable exemption. 
The repeal of this mandate means that fewer consumers may carry insurance coverage and therefore may be less likely to 
elect to receive our testing because they would be required to pay out of pocket for such tests, which could impact our test 
volumes and adversely affect our business, financial condition, results of operations, and cash flows. The PPACA also 
created a new system of health insurance “exchanges” designed to make health insurance available to individuals and 
certain groups through state- or federally-administered marketplaces in addition to existing channels for obtaining health 
insurance coverage. If Panorama or any of our other tests are not covered by plans offered in the health insurance exchanges, 
our business,  financial  condition  and  results  of operations could be  adversely  affected. Furthermore, various proposed 
legislative initiatives with respect to the PPACA in the past, including possible repeal of the PPACA, have resulted in 
considerable uncertainty and concern regarding, for example, a patient’s election to undergo genetic screening and whether 
doing so may impact health insurance eligibility. Because it is unclear whether or how the PPACA may continue to evolve, 
be modified, or otherwise change, and whether and to what extent NIPT, cancer screening or other genetic screening may 
be affected, we are uncertain how our business may be impacted. 

In  addition  to  the  PPACA,  various  healthcare  reform  proposals  have  also  emerged  from  federal  and  state 
governments. The Protecting Access to Medicare Act of 2014, or PAMA, introduced a multi-year pricing program for 
services  payable  under  the  CLFS  that  is  designed  to  bring  Medicare  allowable  amounts  in  line  with  the  often  lower 
negotiated payment rates paid by private payers. The implementation of the PAMA rates have negatively impacted overall 
pricing and reimbursement for many clinical laboratory testing services and continue to be the subject of controversy in 
the industry. The new rates under PAMA have had minimal impact on our business because our revenues from Medicare 
have been very low; however, we expect the new rates to have greater impact on us as we increase billing for our Signatera 
and Prospera testing. In addition, federal budgetary limitations and changes in healthcare policy, such as the creation of 
broad limits for our tests and requirements that beneficiaries of government health plans pay for, or pay for higher portions 
of, clinical laboratory tests or services received, could substantially diminish the utilization of our tests, increase costs and 
adversely affect our ability to generate revenues and achieve profitability. 

We cannot predict whether future healthcare initiatives will be implemented at the federal or state level or how 
any such future legislation, regulation or initiative may affect us. Current or potential future federal legislation and the 
expansion of government’s role in the U.S. healthcare industry, as well as changes to the reimbursement amounts paid by 
third-party payers for our current and future tests, may adversely affect our test volumes and adversely affect our business, 
financial condition, results of operations, and cash flows. 

If  we  or  our  laboratory  distribution  partners,  consultants  or  commercial  partners  act  in  a  manner  that  violates 
healthcare fraud and abuse laws or otherwise engage in misconduct, we may be subject to civil or criminal penalties. 

We are subject to healthcare fraud and abuse regulation and enforcement by both the U.S. federal government 

and the states in which we conduct our business, including: 

57 

•  HIPAA,  which  created  federal  civil  and  criminal  laws  that  prohibit  executing  a  scheme  to  defraud  any 
healthcare  benefit  program  or  making  false  statements  relating  to  healthcare  matters  and  also  imposes 
significant  obligations  with  respect  to  maintenance  of  the  privacy  and  security,  and  transmission,  of 
individually identifiable health information; 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

federal and state laws and regulations governing informed consent for genetic testing and the use of genetic 
material; 

federal and state laws and regulations governing the submission of claims, as well as billing and collection 
practices, for healthcare services; 

the federal Anti-Kickback Statute, which prohibits, among other things, the knowing and willful solicitation, 
receipt,  offer  or  payment  of  remuneration,  directly  or  indirectly,  in  exchange  for  or  to  induce  either  the 
referral of an individual for, or the purchase, order or recommendation of, any good or service for which 
payment may be made under federal healthcare programs such as Medicare; 

the federal  False  Claims Act  which prohibits,  among other  things,  the  presentation of  false  or fraudulent 
claims for payment from Medicare, Medicaid, or other government-funded third-party payers; 

federal laws and regulations governing the Medicare program, providers of services covered by the Medicare 
program, and the submission of claims to the Medicare program, as well as the Medicare Manuals issued by 
CMS and the local medical policies promulgated by the Medicare Administrative Contractors with respect 
to the implementation and interpretation of such laws and regulations; 

the federal Stark law, also known as the physician self-referral law, which, subject to certain exceptions, 
prohibits a physician from making a referral for certain designated health services covered by the Medicare 
program  (and  according  to  case  law  in  some  jurisdictions,  the  Medicaid  program  as  well),  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; 

the federal Civil Monetary Penalties Law, which, subject to certain exceptions, prohibits, among other things, 
the  offer  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; 

the Eliminating Kickbacks in Recovery Act of 2018, or EKRA, which, among other things, prohibits the 
knowing or willful payment or offer, or the 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; 

the prohibition on reassignment by the program beneficiary of Medicare claims to any party; and 

state law equivalents of the above U.S. federal laws, such as the Stark law, Anti-Kickback Statute and false 
claims laws, which may apply to items or services reimbursed by any third-party payer, including commercial 
insurers, and state data privacy and security laws and which may be more stringent than HIPAA. 

Furthermore, a development affecting our industry is the increased enforcement of the federal False Claims Act 
and, in particular, actions brought pursuant to the False Claims Act’s “whistleblower” or “qui tam” provisions. The False 
Claims  Act  imposes  liability  for,  among  other  things,  knowingly  presenting,  or  causing  to  be  presented,  a  false  or 
fraudulent claim for payment by a federal governmental payer program. The qui tam provisions of the False Claims Act 
allow a private individual to bring civil actions on behalf of the federal government for violations of the False Claims Act 
and permit such individuals to share in any amounts paid by the defendant to the government in fines or settlement. When 
an entity is determined to have violated the False Claims Act, it is subject to mandatory damages of three times the actual 
damages sustained by the government, plus mandatory civil penalties of up to approximately $22,363 for each false claim. 

58 

In addition, various states have enacted false claim laws analogous to the federal False Claims Act, and in some cases go 
even further because many of these state laws apply where a claim is submitted to any third-party payer and not merely a 
governmental payer program. For example, in 2018 we reached a settlement with certain government payers regarding 
past reimbursement submissions. Although the settlement involved no admission of fault by us and no corporate integrity 
agreement, we cannot guarantee that we will not be subject to similar claims in the future. 

Many of these laws and regulations have not been fully interpreted by regulatory authorities or the courts, and 
their provisions are open to a variety of interpretations. We have adopted policies and procedures designed to comply with 
these laws, and in the ordinary course of our business, we conduct internal reviews of our compliance with these laws. 
However, the rapid growth and expansion of our business both within and outside of the United States may increase the 
potential for violating these laws or our internal policies and procedures, and the uncertainty around the interpretation of 
these laws and regulations increases the risk that we may be found in violation of these or other laws and regulations, or 
of allegations of such violations, including pursuant to private qui tam actions brought by individual whistleblowers in the 
name  of  the  government  as  described  above.  If  our  operations,  including  the  conduct  of  our  employees,  distributors, 
consultants and commercial partners, are found to be in violation of any laws or regulations that apply to us, we may be 
subject  to  penalties,  including  civil,  criminal  and  administrative  penalties,  damages,  fines,  disgorgement  of  profits, 
exclusion from participation in government programs, injunctions, recall or seizure of products, total or partial suspension 
of  production,  denial  or  withdrawal  of  pre-marketing  product  approvals,  contractual  damages,  reputational  harm, 
diminished profits and future earnings and the curtailment or restructuring of our operations, any of which could materially 
and adversely affect our business, financial condition and results of operations. 

Failure to comply with privacy and security laws and regulations could result in fines, penalties and damage to our 
reputation and have a material adverse effect on our business. 

The  federal  HIPAA  privacy  and  security  regulations,  including  the  expanded  requirements  under  the  Health 
Information Technology for Economic and Clinical Health Act, or HITECH, which was enacted as part of the American 
Recovery and Reinvestment Act of 2009, establish comprehensive federal standards with respect to the use and disclosure 
of protected health information by health plans, healthcare providers, and healthcare clearinghouses, in addition to setting 
standards to protect the confidentiality, integrity and security of protected health information. The regulations establish a 
complex  regulatory  framework  on  a  variety  of  subjects,  including  patient  authorization  of  the  use  and  disclosure  of, 
administrative,  technical  and  physical  safeguards  for,  and  analysis  of  security  incidents  and  breach  notification 
requirements with respect to, protected health information. HIPAA, as amended by HITECH, provides for significant fines 
and other penalties for wrongful use or disclosure of protected health information in violation of privacy and security 
regulations, including potential civil and criminal fines and penalties. 

The HIPAA privacy and security regulations establish minimum requirements, and do not supersede state laws 
that are more stringent. A number of states include medical information in the definition of personal information and have 
implemented requirements or standards more stringent than HIPAA. Therefore, while we have implemented policies and 
procedures related to compliance with the HIPAA regulations, we are also required to comply with various state privacy 
and security laws and regulations, and could incur penalties, compliance costs as a result of non-compliance or damages 
under state laws pursuant to an action brought by a private party for the wrongful use or disclosure of confidential health 
information or other private personal information. In addition, other federal and state laws that protect the privacy and 
security of patient information may be subject to enforcement and interpretation by various governmental authorities and 
courts, resulting in complex compliance issues. 

The  European  Union’s  data  privacy  regulations,  the  General  Data  Protection  Regulation,  or  GDPR,  became 
subject  to  enforcement  in  May  2018.  These  regulations  comprehensively  reform  the  prior  data  protection  rules  of  the 
European Union, and are more stringent, provide for higher potential liabilities, and apply to a broader range of personal 
data than those in the United States. The GDPR is applicable to U.S.-based companies, such as ours, that do business or 
offer services in, or that process or hold personal data of data subjects in, the European Union. While our current processes 
and practices comply with the GDPR, we will need to expend considerable time and resources, including management 
attention, to continue to revise our practices to ensure ongoing compliance with GDPR. Furthermore, the GDPR enables 
EU member states to enact jurisdiction-specific requirements in key areas, which could require us to modify our plans to 

59 

comply with the GDPR, or otherwise to implement multiple policies unique to the jurisdictions in which we operate, which 
could make it more difficult and resource-intensive to continue to operate in the European Union. 

As we continue to expand and grow our business, our overall compliance with applicable laws and regulations 
may result in increased costs and attention of management, and failure to comply may result in significant fines, penalties 
and damage to our reputation. Additionally, the interpretation and application of health-related, privacy and data protection 
laws are often uncertain, contradictory and in flux, and it is possible that these laws may be interpreted and applied in a 
manner that is inconsistent with our practices. As a result, we could be subject to government-imposed fines or orders 
requiring  that  we  change  our  practices,  which  could  cause  us  to  incur  substantial  costs  and  may  adversely  affect  our 
business and our reputation. 

Changes in the way the FDA regulates the reagents, other consumables, and testing equipment we use when developing, 
validating,  and  performing  our  tests  could  result  in  delay  or  additional  expense  in  bringing  our  tests  to  market  or 
performing such tests for our customers. 

Many of the sequencers, reagents, kits and other consumable products used to perform our testing, as well as the 
instruments and other capital equipment that enable the testing, are labeled as for research use only, or RUO. In addition, 
we offer a version of our Signatera test as a research use only offering. Products that are intended for research use only 
and  are  labeled  as  RUO  are  exempt  from  compliance  with  FDA  requirements,  including  the  approval,  clearance  or 
authorization and other product quality requirements for medical devices. A product labeled RUO but which is actually 
intended for clinical diagnostic use may be viewed by the FDA as adulterated and misbranded under the FDC Act and 
subject to FDA enforcement action. The FDA has issued guidance stating that when determining the intended use of a 
product labeled RUO, it will consider the totality of the circumstances surrounding distribution of the product, including 
how the product is marketed and to whom. In addition, many of the reagents used to perform our testing are offered for 
sale as analyte specific reagents, or ASRs. ASRs are medical devices and must comply with QSR provisions and other 
device  requirements,  but  most  are  exempt  from  510(k)  and  PMA  premarket  review.  The  FDA  could  disagree  with  a 
manufacturer’s assessment that the manufacturer’s products are ASRs, or could conclude that products labeled as RUO 
are actually intended for clinical diagnostic use, and could take enforcement action against the manufacturer, such as us 
with respect to Signatera (RUO), including requiring the manufacturer to cease offering the product while it seeks clearance, 
approval  or  authorization.  Manufacturers  of  RUO  products  that  we  employ  in  our  other  tests  may  cease  selling  their 
respective products, and we may be unable to obtain an acceptable substitute on commercially reasonable terms or at all, 
which  could  significantly  and  adversely  affect  our  ability  to  provide  timely  testing  results  to  our  customers  or  could 
significantly increase our costs of conducting business. 

The sequencers and reagents supplied to us by Illumina and the blood collection tubes supplied to us by Streck 
are labeled as RUO in the United States. We are using these sequencers, reagents and blood collection tubes for clinical 
diagnostic use. If the FDA were to require clearance, approval or authorization for the sale of Illumina’s sequencers and 
if Illumina does not obtain such clearance, approval or authorization, we would have to find an alternative sequencing 
platform for Panorama. We currently have not validated an alternative sequencing platform on which Panorama 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 decision by the FDA to require clearance, approval or authorization for the sale 
by Streck of the blood collection tubes used for Panorama, or a finding that any of our other suppliers failed to comply 
with applicable requirements, could result in interruptions in our ability to supply our products to the market and adversely 
affect our operations. 

Our use of hazardous materials in the development of our tests exposes us to risks related to accidental contamination 
or injury and requires us to comply with regulations governing hazardous waste materials. 

Our research and development activities involve the controlled use of hazardous materials and chemicals. We 
cannot eliminate the risk of accidental contamination or injury to employees or third parties from the use, storage, handling 
or disposal of these materials. In the event of contamination 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. In addition, we are subject 
on  an  ongoing  basis  to  federal,  state  and  local  regulations  governing  the  use,  storage,  handling  and  disposal  of  these 

60 

materials and specified hazardous waste materials. An increase in the costs of compliance with such laws and regulations 
could harm our business and results of operations. 

If the validity of an informed consent from a patient intake for Panorama or our other tests is challenged, we could be 
precluded from billing for such testing, forced to stop performing such tests, or required to repay amounts previously 
received, which would adversely affect our business and financial results. 

All clinical data and blood samples that we receive are required to have been collected from individuals who have 
provided appropriate informed consent for us to perform our testing, both commercially and in clinical trials. We seek to 
ensure that the individuals from whom the data and samples are collected do not retain or have conferred any proprietary 
or  commercial  rights  to  the  data  or  any  discoveries  derived  from  them.  Our  partners  operate  in  a  number  of  different 
countries  in  addition  to  the  United  States,  and,  to  a  large  extent,  we  rely  upon  them  to  comply  with  the  individual’s 
informed  consent  and  with  U.S.  and  international  laws  and  regulations.  The  collection  of  data  and  samples  in  many 
different states and foreign countries results in complex legal questions regarding the adequacy of informed consent and 
the status of genetic material under a large number of different legal systems. The individual’s informed consent obtained 
in any particular country could be challenged in the future, and those informed consents could be deemed invalid, unlawful 
or otherwise inadequate for our purposes. Any findings against us, or our partners, could deny us access to, or force us to 
stop testing samples in, a particular country or could call into question the results of our clinical trials. We could also be 
precluded from billing third-party payers for tests for which informed consents are challenged, or could be requested to 
refund amounts previously paid by third-party payers for such tests. We could become involved in legal challenges, which 
could require significant management and financial resources and adversely affect our revenues and results of operations. 

Risks Related to Our Intellectual Property 

Litigation  or  other  proceedings  resulting  from  either  third-party  claims  of  intellectual  property  infringement,  or 
asserting  infringement  by  third  parties  of  our  technology,  is  costly,  time-consuming,  and  could  limit  our  ability  to 
commercialize our products or services. 

Our success depends in part on our non-infringement of the patents or intellectual property rights of third parties, 
and our ability to successfully prevent third parties from infringing our intellectual property. We operate in a crowded 
technology area in which there has been substantial litigation and other proceedings regarding patent and other intellectual 
property rights in the genetic diagnostics industry. Third parties, including our competitors, have asserted and may in the 
future assert that we are infringing their intellectual property rights. 

We are or have recently been engaged in patent infringement lawsuits and other intellectual property disputes 
against various competitors in each of the industries in which we operate, as described in “Note 8—Commitments and 
Contingencies—Legal Proceedings” in the Notes to Consolidated Financial Statements. We may become subject to and/or 
initiate future intellectual property litigation as our product portfolio, and the level of competition in our industry segments, 
grow. 

Should we be unsuccessful defending against patent infringement claims, we may be required to pay substantial 
royalties, money damages, or be enjoined from offering certain products or services. We may be required to change our 
marketing practices, pay large damages awards, and in the case of patent infringement, pay unsustainably high royalties 
to obtain licenses from third parties. In addition, we could experience delays in product introductions or sales growth while 
we attempt to develop non-infringing alternatives. Any of these or other adverse outcomes could prevent us from offering 
our tests or otherwise have a material adverse effect on our business, financial condition and our results of operations. 

We cannot predict whether, or offer any assurance that, the patent infringement claims we have initiated or may 
initiate in the future will be successful. We are and may become subject to counterclaims by patent infringement defendants. 
Our patents may be declared invalid or unenforceable, or narrowed in scope. Even if we prevail in an infringement action, 
we cannot assure you that we would be adequately compensated for the harm to our business. If we are unable to enjoin 
third-party infringement, our revenues may be adversely impacted and we may lose market share; and such third-party 
product may continue to exist in the market, but fail to meet our regulatory or safety standards, thereby causing irreparable 

61 

harm to our reputation as a provider of quality products, which in turn could result in loss of market share and have a 
material adverse effect on our business, financial condition and our results of operations. 

In addition, our agreements with some of our customers, suppliers, and other entities with whom we do business 
require us to defend or indemnify these parties to the extent they become involved in patent infringement claims, including 
the types of claims described in this risk factor. We have agreed, and may in the future agree, to defend or indemnify third 
parties if we determine it to be in the best interests of our business relationships. If we are required or agree to defend or 
indemnify third parties in connection with any infringement claims, we could incur significant costs and expenses that 
could adversely affect our business, financial condition and results of operations. 

Any inability to effectively protect our proprietary technologies could harm our competitive position. 

Our success and ability to compete depend to a large extent on our ability to develop proprietary products and 
technologies and to maintain adequate protection of our intellectual property in the United States and other countries; this 
becomes  increasingly  important  as  we  expand  our  operations  and  enter  into  strategic  collaborations  with  partners  to 
develop and commercialize products. The laws of some foreign countries do not protect proprietary rights to the same 
extent as the laws of the United States, and we may encounter difficulties in establishing and enforcing our proprietary 
rights outside of the United States. In addition, the proprietary positions of companies developing and commercializing 
tools for molecular diagnostics, including ours, generally are uncertain and involve complex legal and factual questions. 
This  uncertainty  may  materially  affect  our  ability  to  defend  or  obtain  patents  or  to  address  the  patents  and  patent 
applications owned or controlled by our collaborators and licensors. 

We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our 
proprietary technologies are protected by valid and enforceable patents or are effectively maintained as trade secrets. We 
have worked to procure patents protecting our technologies, but our procurement efforts may not always be successful, 
and  any patents  we successfully  procure  may be  challenged  in  ways  that  lead  to  post-procurement scope  reduction or 
invalidity. For example, certain of our intellectual property is, or recently has been, the subject of challenges instituted by 
our  competitors,  as  described  in  “Note 8—Commitments  and  Contingencies—Legal  Proceedings”  in  the  Notes  to 
Consolidated  Financial  Statements.  These  challenges  may  impede  our  ability  to  protect  our  proprietary  rights  from 
unauthorized use. In addition, any finding that others have claims of 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. 

Certain of our intellectual property was partly supported by a U.S. government grant awarded by the National 
Institutes  of  Health,  and  the  government  accordingly  has  certain  rights  in  this  intellectual  property,  including  a 
non-exclusive, non-transferable, irrevocable worldwide license to use applicable inventions for any governmental purpose. 
Such rights also include “march-in” rights, which refer to the right of the U.S. government to require us to grant a license 
to the technology to a responsible applicant if we fail to achieve practical application of the technology or if action is 
necessary to alleviate health or safety needs, to meet requirements of federal regulations or to give preference to U.S. 
industry. 

Any  of  these  factors  could  adversely  affect  our  ability  to  obtain  commercially  relevant  or  competitively 

advantageous patent protection for our products. 

If we are not able to adequately protect our trade secrets and other proprietary information, the value of our technology 
and products could be significantly diminished. 

We rely on trade secret and proprietary know-how protection for our confidential and proprietary information 
and  have  taken  security  measures  to  protect  this  information.  These  measures,  however,  may  not  provide  adequate 
protection. For example, we have a policy of requiring our consultants, advisors and collaborators, including, for example, 
our  strategic  collaborators  with  whom  we  seek  to  develop  and  commercialize  products,  to  enter  into  confidentiality 
agreements and our employees to enter into invention, non-disclosure and non-compete agreements. However, breaches 
of our physical or electronic security systems, or breaches caused by our employees failing to abide by their confidentiality 
obligations during or upon termination of their employment with us, could compromise these protection efforts. Any action 

62 

we  take  to  enforce  our  rights  may  be  time-consuming,  expensive,  and  possibly  unsuccessful.  Even  if  successful,  the 
resulting remedy may not adequately compensate us for the harm caused by the breach. These risks are heightened in 
countries where laws or law enforcement practices may not protect proprietary rights as fully as in the United States or 
Europe. Any unauthorized use or disclosure of, or access to, our trade secrets, know-how or other proprietary information, 
whether accidentally or through willful misconduct, could have a material adverse effect on our programs and our strategy, 
and on our ability to compete effectively. 

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

Failure to maintain our trademark registrations, or to obtain new trademark registrations in the future, could limit 
our ability to protect our trademarks and impede our marketing efforts in the countries in which we operate. We may not 
be able to protect our rights to trademarks and trade names which we may need to build name recognition with potential 
partners or customers in our markets of interest. As a means to enforce our trademark rights and prevent infringement, we 
may be required to file trademark claims against third parties or initiate trademark opposition proceedings. This can be 
expensive and time-consuming, and possibly unsuccessful. Our registered or unregistered trademarks or trade names may 
be challenged, infringed, circumvented, declared generic or determined to infringe on other marks. 

Our pending trademark applications in the United States and in other foreign jurisdictions where we may file may 
not be successful. Even if these applications result in registered trademarks, third parties may challenge these trademarks 
in the future. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, 
then we may not be able to compete effectively and our business may be adversely affected. 

We  may  be  subject  to  claims  that  our  employees,  consultants  or  independent  contractors  have  wrongfully  used  or 
disclosed confidential information of third parties. 

We employ individuals who were previously employed at other biotechnology or diagnostic companies. We may 
be subject to claims that we or our employees, consultants or independent contractors have inadvertently or willfully used 
or disclosed confidential information of our employees’ former employers or other third parties. We may also be subject 
to claims that our employees’ former employers or other third parties have an ownership interest in our patents. Litigation 
may  be  necessary  to  defend  against  these  claims,  and  if  we  are  unsuccessful,  we  could  be  required  to  pay  substantial 
damages  and  could  lose  rights  to  important  intellectual  property.  Even  if  we  are  successful,  litigation  could  result  in 
substantial costs to us and could divert the time and attention of our management and other employees. 

Risks Related to our Convertible Notes 

Servicing our debt will require a significant amount of cash. We may not have sufficient cash flow from our business 
to pay our outstanding debt, and we may not have the ability to raise the funds necessary to settle conversions of the 
Convertible Notes in cash or to repurchase the Convertible Notes upon a fundamental change, which could adversely 
affect our business and results of operations. 

Our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our indebtedness, 
including  the  amounts  payable  under  the  Convertible  Notes,  depends  on  our  future  performance,  which  is  subject  to 
economic, financial, competitive, and other factors beyond our control. Our business may not continue to generate cash 
flow from operations in the future sufficient to service our indebtedness and make necessary capital expenditures. If we 
are  unable  to  generate  such  cash  flow,  we  may  be  required  to  adopt  one  or  more  alternatives,  such  as  selling  assets, 
restructuring debt, or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to 
refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be 
able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on 
our debt obligations. 

Further,  holders  of  the  Convertible  Notes  have  the  right  to  require  us  to  repurchase  all  or  a  portion  of  their 
Convertible Notes upon the occurrence of a “fundamental change” (as defined in the indenture governing the Convertible 
Notes) before the maturity date at a repurchase price equal to 100% of the principal amount of the Convertible Notes to 

63 

be repurchased, plus accrued and unpaid interest, if any. In addition, upon conversion of the Convertible Notes, unless we 
elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering 
any fractional share), we will be required to make cash payments in respect of the Convertible Notes being converted. 
However, we may not have enough available cash, or be able to obtain sufficient financing, at the time we are required to 
repurchase the Convertible Notes. 

The  conditional  conversion  feature  of  the  Convertible  Notes,  when  triggered,  may  adversely  affect  our  financial 
condition and operating results. 

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

In addition, even if holders of Convertible Notes do not elect to convert their Convertible Notes, we could be 
required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Convertible 
Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital. 

The accounting method for convertible debt securities that may be settled in cash, such as the Convertible Notes, could 
have a material effect on our reported financial results. 

The accounting method for reflecting the Convertible Notes on our balance sheet, accruing interest expense for 
the Convertible Notes and reflecting the underlying shares of our common stock in our reported diluted earnings per share 
may adversely affect our reported earnings and financial condition. 

We expect that, under applicable accounting principles, the initial liability carrying amount of the Convertible 
Notes will be the fair value of a similar debt instrument that does not have a conversion feature, valued using our cost of 
capital for straight, unconvertible debt. We have reflected the difference between the net proceeds from the sale of the 
Convertible Notes and the initial carrying amount as a debt discount for accounting purposes, which is amortized into 
interest  expense  over  the  term  of  the  Convertible  Notes.  As  a  result  of  this  amortization,  the  interest  expense  to  be 
recognized for the Convertible Notes for accounting purposes will be greater than the cash interest payments we will pay 
on the Convertible Notes, which results in lower reported net income. The lower reported income (or higher net loss) 
resulting from this accounting treatment could depress the trading price of our common stock and the Convertible Notes. 

Under historical accounting standards, under certain circumstances we would be eligible to use the treasury stock 
method to reflect the shares underlying the Convertible Notes in our diluted earnings per share. Under this method, if the 
conversion value of the Convertible Notes exceeds their principal amount for a reporting period, then we will calculate 
our diluted earnings per share assuming that all the Convertible Notes were converted and that we issued shares of our 
common stock to settle the excess. However, if reflecting the Convertible Notes in diluted earnings per share in this manner 
is anti-dilutive, or if the conversion value of the Convertible Notes does not exceed their principal amount for a reporting 
period, then the shares underlying the Convertible Notes will not be reflected in our diluted earnings per share. In August 
2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2020-06, Debt—Debt with 
Conversion  and  Other  Options  (Subtopic  470-20)  and  Derivatives  and  Hedging—Contracts  in  Entity’s  Own  Equity 
(Subtopic 815-40). This guidance, which will be effective for fiscal years beginning after December 15, 2021 (including 
interim periods within those fiscal years) eliminated the treasury stock method for convertible instruments such as the 
Convertible Notes and instead requires application of the “if-converted” method. Under that method, once adopted, diluted 
earnings per share would generally be calculated assuming that all the Convertible Notes were converted solely into shares 
of common stock at the beginning of the reporting period, unless the result would be anti-dilutive. The application of the 
if-converted method may reduce our reported diluted earnings per share. 

Furthermore, if any of the conditions to the convertibility of the Convertible Notes is satisfied, then we may be 
required  under  applicable  accounting  standards  to  reclassify  the  liability  carrying  value  of  the  Convertible  Notes  as  a 

64 

current,  rather  than  a  long-term,  liability.  This  reclassification  could  be  required  even  if  no  noteholders  convert  their 
Convertible Notes and could materially reduce our reported working capital. 

Conversion of the Convertible Notes will dilute the ownership interest of existing stockholders, including holders who 
had previously converted their Convertible Notes, or may otherwise depress the price of our common stock. 

The conversion of some or all of the Convertible Notes will dilute the ownership interests of stockholders to the 
extent we deliver shares of our common stock upon such conversion. The Convertible Notes are currently convertible and 
may from time to time in the future be convertible at the option of their holders prior to their scheduled terms under certain 
circumstances. Any sales in the public market of the common stock issuable upon such conversion could adversely affect 
prevailing market prices of our common stock. In addition, the existence of the Convertible Notes may encourage short 
selling by market participants because the conversion of the Convertible Notes could be used to satisfy short positions, or 
anticipated conversion of the Convertible Notes into shares of our common stock could depress the price of our common 
stock. 

Risks Related to Ownership of Our Common Stock 

The market price of our common stock has been and may be volatile, which could subject us to litigation. 

The trading prices of the securities of life sciences companies, including ours, have been and may continue to be 
highly volatile. Accordingly, the market price of our common stock is likely to be subject to wide fluctuations in response 
to  numerous  factors,  many  of  which  are  beyond  our  control,  such  as  those  in  this  “Risk  Factors”  section  and  others 
including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

actual or anticipated variations in our and our competitors’ results of operations, as well as how those results 
compare to analyst and investor expectations; 

announcements by us or our competitors of new products, significant acquisitions, other strategic transactions, 
including strategic and commercial partnerships and relationships, joint ventures, divestitures, collaborations 
or capital commitments; 

changes in reimbursement practices by current or potential payers; 

failure  of  analysts  to  initiate  or  maintain  coverage  of  our  company,  issuance  of  new  securities  analysts’ 
reports or changed recommendations for our stock; 

forward-looking statements related to our financial guidance or projections, our failure to meet or exceed our 
financial guidance or projections or changes in our financial guidance or projections; 

actual or anticipated changes in regulatory oversight of our products; 

development of disputes concerning our intellectual property or other proprietary rights; 

commencement of, or our involvement in, litigation; 

announcement or expectation of additional debt or equity financing efforts; 

any major change in our management; and 

general economic conditions and slow or negative growth of our markets. 

In  addition,  if  the  market  for  life  sciences  stocks  or  the  stock  market  in  general  experiences  uneven  investor 
confidence, the market price of our common stock could decline for reasons unrelated to our business, operating results or 
financial  condition.  The  market  price  of  our  common  stock  might  also  decline  in  reaction  to  events  that  affect  other 

65 

companies within, or outside, our industry even if these events do not directly affect us. Some companies, including us, 
that have experienced volatility in the trading price of their stock have been the subject of securities class action litigation. 
For example, we have in the past been subject to a purported securities class action lawsuit filed against us, our directors 
and certain of our officers and stockholders related to our initial public offering. Under certain circumstances, we have 
contractual and other legal obligations to indemnify and to incur legal expenses on behalf of current and former directors 
and officers, and on behalf of our former underwriters, in connection with any future lawsuits. Any lawsuit to which we 
are  a  party,  with  or  without  merit,  may  result  in  an  unfavorable  judgment.  We  also  may  decide  to  settle  lawsuits  on 
unfavorable terms. Any such negative outcome could result in payments of substantial damages or fines, damage to our 
reputation  or  adverse  changes  to  our  offerings  or  business  practices.  Defending  against  litigation  is  costly  and 
time-consuming, and could divert our management’s attention and resources. Furthermore, during the course of litigation, 
there  could  be  negative  public  announcements  of  the  results  of  hearings,  motions  or  other  interim  proceedings  or 
developments, which could have a material adverse effect on the market price of our common stock. 

Commencing  December 31,  2019,  we  were  no  longer  an  “emerging  growth  company,”  and  the  reduced  disclosure 
requirements applicable to emerging growth companies no longer apply to us. 

As of December 31, 2019, we ceased to qualify as an “emerging growth company”, as defined by the Jumpstart 
Our Businesses Act of 2012, or the JOBS Act, because as of June 30, 2019, the market value of our common stock that 
was held by non-affiliates exceeded $700 million. As a result, we are no longer permitted to take advantage of reduced 
regulatory  and  reporting  requirements  that  are  otherwise  generally  applicable  to  public  companies.  These  include,  not 
being required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act, reduced 
disclosure obligations regarding executive compensation, and exemptions from the requirements of holding non-binding 
advisory  votes  on  executive  compensation  and  golden  parachute  payments.  As  we  are  no  longer  an  emerging  growth 
company, we expect to incur additional expenses and devote substantial management effort toward ensuring compliance 
with  those  requirements  applicable  to  companies  that  are  not  emerging  growth  companies.  Compliance  with  these 
additional laws, rules and regulations has and will continue to increase our legal and financial compliance costs, make 
some activities more difficult, time consuming or costly and increase demand on our systems and resources. In addition, 
management’s attention may be diverted from other business concerns and our costs and expenses will increase, which 
could harm our business and operating results. We may also need to hire more employees in the future or engage additional 
outside consultants to comply with these requirements, which will increase our costs and expenses. 

If we are unable to implement and maintain effective internal controls over financial reporting in the future, investors 
may lose confidence in the accuracy and completeness of our financial reports and the market price of our common 
stock could be adversely affected. 

We are required to maintain internal controls over financial reporting and to report any material weaknesses in 
such internal controls. Section 404 of the Sarbanes-Oxley Act requires that we evaluate and determine the effectiveness 
of  our  internal  controls  over  financial  reporting  and  provide  a  management  report  on  internal  controls  over  financial 
reporting. The Sarbanes-Oxley Act also requires that our management report on internal controls over financial reporting 
be attested to by our independent registered public accounting firm. 

Although we determined that our internal controls over financial reporting were effective as of December 31, 
2020, we must continue to monitor and assess our internal controls over financial reporting. If we have a material weakness 
in our internal controls over financial reporting, we may not detect errors on a timely basis and our financial statements 
may be materially misstated. If we identify material weaknesses in our internal controls over financial reporting, if we are 
unable to comply with the requirements of Section 404 in a timely manner, if we are unable to assert that our internal 
controls  over  financial  reporting  are  effective,  or,  when  required  in  the  future,  if  our  independent  registered  public 
accounting firm is unable to express an opinion as to the effectiveness of our internal controls over financial reporting, 
investors  may  lose  confidence  in  the  accuracy  and  completeness  of  our  financial  reports  and  the  market  price  of  our 
common stock could be adversely affected, and we could become subject to investigations by the stock exchange on which 
our securities are listed, the SEC, or other regulatory authorities. 

66 

We do not intend to pay dividends on our capital stock so any returns will be limited to changes in the value of our 
common stock. 

We have never declared or paid any cash dividends on our capital stock. We currently anticipate that we will 
retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or 
paying any cash dividends for the foreseeable future. In addition, our ability to pay cash dividends on our capital stock 
may be prohibited or limited by the terms of any current or future debt financing arrangement. Any return to stockholders 
will therefore be limited to the increase, if any, in the price of our common stock. 

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

From time to time, we may issue additional securities or sell common stock, convertible securities or other equity 
securities in one or more transactions at prices and in a manner we determine. We also expect to continue to issue common 
stock to employees and directors pursuant to our equity incentive plans. If we sell or issue common stock, convertible 
securities, or other equity securities, or common stock is issued pursuant to equity incentive plans, investors in our common 
stock may be materially diluted. We may decide to issue common stock or other equity securities in connection with an 
acquisition or a strategic or commercial transaction, which could cause dilution to our existing stockholders. New investors 
in such transactions could gain rights, preferences and privileges senior to those of holders of our common stock. 

Sales of a substantial number of shares of our common stock in the public markets could cause the price of our common 
stock to decline. 

Sales of a substantial number of shares of our common stock in the public market or the perception that these 
sales might occur could depress the market price of our common stock and could impair our ability to raise capital through 
the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market 
price of our common stock. 

We  may  issue  our  shares  of  common  stock  or  securities  convertible  into  our  common  stock,  such  as  our 
Convertible Notes,  from  time  to  time  in  connection  with a  financing,  acquisition,  investments or otherwise. Any  such 
issuance could result in substantial dilution to our existing stockholders and cause the price of our common stock to decline. 

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

The trading market for our common stock depends in part on the research and reports that securities or industry 
analysts publish about us or our business. Currently, only a small number of securities analysts cover our stock. If more 
analysts do not commence coverage of us, or if industry analysts cease coverage of us or fail to publish reports on us 
regularly, the trading price for our common stock could be adversely affected. If one or more of the analysts who cover us 
downgrade our common stock or publish inaccurate or unfavorable research about our business, our common stock price 
would likely decline. 

Insiders have substantial control over us and will be able to influence corporate matters. 

As  of  December  31,  2020,  our  directors  and  executive  officers  and  their  affiliates  beneficially  owned,  in  the 
aggregate, approximately 10.68% of our outstanding capital stock. As a result, these stockholders are and will continue to 
be able to exercise significant influence over all matters requiring stockholder approval, including the election of directors 
and  approval  of  significant  corporate  transactions,  such  as  a  merger  or  other  sale  of  our  company  or  its  assets.  This 
concentration of ownership could limit stockholders’ ability to influence corporate matters and may have the effect of 
delaying or preventing a third party from acquiring control over us. 

Provisions in our amended and restated certificate of incorporation, amended and restated bylaws, and Delaware 
law might discourage, delay or prevent a change in control of our company or changes in our management and, therefore, 
depress the market price of our common stock. 

67 

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

• 

• 

• 

• 

• 

• 

• 

• 

• 

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

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

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

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; 

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

permit the board of directors to establish the number of directors; 

provide  that  directors  may  only  be  removed  “for  cause”  and  only  with  the  approval  of  75%  of  our 
stockholders; 

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

provide that the board of directors is expressly authorized to make, alter or repeal our amended and restated 
bylaws. 

In addition, Section 203 of the Delaware General Corporation Law may discourage, delay or prevent a change in 
control of our company. Section 203 imposes certain restrictions on mergers, business combinations and other transactions 
between us and holders of 15% or more of our common stock. 

In addition, if a “fundamental change” (as defined in the indenture governing the Convertible Notes) occurs prior 
to the maturity date of the Convertible Notes, holders of the Convertible Notes will have the right, at their option, to require 
us to repurchase all or a portion of their Convertible Notes. If a “make-whole fundamental change” (as defined in the 
indenture governing the Convertible Notes) occurs prior to the maturity date, we will in some cases be required to increase 
the conversion rate of the Convertible Notes for a holder that elects to convert its Convertible Notes in connection with 
such make-whole fundamental change. Furthermore, we are prohibited from engaging in certain mergers or acquisitions 
unless, among other things, the surviving entity of such transaction assumes our obligations under the Convertible Notes. 

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is 
the exclusive forum 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 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 pursuant to the Delaware General Corporation 
Law  or  any  action  asserting  a  claim  against  us  that  is  governed  by  the  internal  affairs  doctrine.  This  choice  of  forum 
provision 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 and may discourage these types of lawsuits. Alternatively, if a court were to 
find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an 
action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our 
business, financial condition and results of operations. 

68 

Changes in accounting standards and their interpretations could adversely affect our operating results. 

U.S. GAAP is subject to interpretation by the Financial Accounting Standards Board, or FASB, the Public 

Company Accounting Oversight Board, or PCAOB, the SEC, and various other bodies that promulgate and interpret 
appropriate accounting principles. These principles and related implementation guidelines and interpretations can be 
highly complex and involve subjective judgments. A change in these principles or interpretations, including with respect 
to the accounting for the Convertible Notes, could have a significant effect on our reported financial results, and could 
affect the reporting of transactions completed before or after the announcement of a change in such principles. 
Additionally, the adoption of these standards may potentially require enhancements or changes in our systems and will 
require significant time and cost on behalf of our financial management. A discussion of these standards and other 
pending changes in GAAP, are further discussed in “Note 2—Summary of Significant Accounting Policies” in the Notes 
to Consolidated Financial Statements.

PROPERTIES  

We lease office facilities under non-cancelable operating lease agreements. We currently occupy approximately 
136,000 square feet of laboratory and office space at 201 Industrial Road in San Carlos, California pursuant to a lease that 
we directly entered into with our landlord in October 2016. This lease covers two office spaces (the “First Space” and the 
“Second Space”). The First Space covers approximately 88,000 square feet at an average base rent of $340,972 per month 
for the year 2020. The Second Space covers approximately 48,000 square feet at an average base rent of $197,605 per 
month. The original lease term is approximately 84 months and expires in October 2023. In January 2021, we entered into 
an amendment of the lease to extend the term for 48 months to October 2027. The combined monthly rent for the First 
Space and Second Space will be $776,671 commencing in October 2023. 

We entered into a sublease agreement in June 2019 with a third party to sublease 25,879 square feet of space 
located on the third floor of the San Carlos, California building while maintaining its primary obligation as the intermediate 
lessor. The term of this lease is approximately 48 months commencing in October 2019 and expiring in September 2023. 
In February 2021, we entered into an amendment of the San Carlos sublease agreement whereas the third party will initially 
return approximately 3,474 rentable square feet with the remainder of the subleased premises, consisting of approximately 
22,405 rentable square feet, between October 2021 and December 2021.  

In Tukwila, Washington, we lease a facility initially to provide storage of our cord blood tissue units. The facility 
covers approximately 10,000 square feet, with a lease term of 62 months beginning in June 2018 and expiring in July 
2023. In the third quarter of 2019, we sold the Evercord business and the facility was subleased to a third party.  

Our subsidiary leases laboratory and office space in Austin, Texas, comprising approximately 94,000 square feet 
pursuant to a lease expiring in November 2026. The lease term is 132 months beginning in December 2015 and expiring 
in November 2026 with monthly payments beginning in December 2016. 

We entered into a lease agreement in November 2020 to lease 11,395 square feet of space located in South San 

Francisco, California over a three-year term. The premises will be used for general office, laboratory and research use. 

We may expand our facilities capacity as our employee base and laboratory processing needs grow. We believe 

that we will be able to obtain additional space on commercially reasonable terms.

LEGAL PROCEEDINGS 

From time to time, we are involved in legal proceedings. The results of such legal proceedings and claims cannot 
be predicted with certainty, and regardless of the outcome, legal proceedings could have an adverse impact on us because 
of defense and settlement costs, diversion of resources and other factors.

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS 

OF OPERATIONS  

You should read the following discussion and analysis of our financial condition and results of operations in conjunction 
with our consolidated financial statements and related notes included in Part II, Item 8 of this report. This discussion 
contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from 
those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those 
identified below and those discussed in “Risk Factors” included elsewhere in this report. 

Overview 

We  are  a  diagnostics  company  with  proprietary  molecular  and  bioinformatics  technology  that  we  deploy  to 
change  the  management  of  disease  worldwide.  Our  technology  has  been  proven  clinically  and  commercially  in  the 
women’s health space, in which we develop and commercialize non- or minimally- invasive tests to evaluate risk for, and 
thereby enable early detection of, a wide range of genetic conditions, such as Down syndrome. We are now translating our 
success in women’s health and applying our core technology in the oncology space, in which we are commercializing a 
personalized blood-based DNA test to detect molecular residual disease and help guide treatment decisions, as well as in 
organ health, with tests to assess the health of organ transplant patients. We seek to enable even wider adoption of our 
technology through Constellation, our global cloud-based distribution model. In addition to our direct sales force in the 
United States, we have a global network of over 100 laboratory and distribution partners, including many of the largest 
international laboratories. 

We currently provide a comprehensive suite of products in women’s health, as well as our offerings in oncology 
and organ health, and our Constellation cloud-based platform. We generate a majority of our revenues from the sale of 
Panorama, our non-invasive prenatal test (“NIPT”), as well as Horizon, our Carrier Screening (“HCS”) test. In addition to 
Panorama and Horizon, our product offerings in women’s health include Spectrum Preimplantation Genetics, our Anora 
miscarriage test, and Vistara single-gene NIPT. Our oncology product is our Signatera molecular residual disease test, 
which we commercialize as a test run in our CLIA laboratory and offer on a research use only (“RUO”) basis to research 
laboratories and pharmaceutical companies; and our primary organ health offering is our Prospera transplant assessment 
test. 

In the year ended December 31, 2020, we processed most of our tests in our laboratory certified under the Clinical 
Laboratory Improvement Amendments of 1988 (“CLIA”) in San Carlos, California, with an increasing number of tests 
processed in our CLIA-certified laboratory in Austin, Texas as we continued to expand our laboratory facilities at that 
location  during  the  year.  A  portion  of  our  testing  is  performed  by  third-party  laboratories.  Our  customers  include 
independent  laboratories,  national  and  regional  reference  laboratories,  medical  centers  and  physician  practices  for  our 
screening tests, and research laboratories and pharmaceutical companies. We market and sell our prenatal screening tests 
both through our direct sales force and through our laboratory distribution partners. We bill clinics, laboratory distribution 
partners,  patients,  pharmaceutical  companies  and  insurance  payers  for  the  tests  we  perform.  In  cases  where  we  bill 
laboratory distribution partners, our partners in turn bill clinics, patients and insurers. The majority of our revenue comes 
from insurers with whom we have in-network contracts. Such insurers reimburse us for NIPT procedures pursuant to our 
in-network contracts with them, based on positive coverage determinations, which means that the insurer has determined 
that NIPT in general is medically necessary for this category of patient. In the United States, the majority of insurance 
providers provide positive NIPT coverage. 

In  addition  to  offering  tests  to  be  performed  at  our  laboratories,  either  directly  or  through  our  laboratory 
distribution  partners,  we  also  establish  licensing  arrangements  with  laboratories  under  Constellation,  our  cloud-based 
distribution  model,  whereby  our  laboratory  licensees  run  the  molecular  workflows  themselves  and  then  access  our 
bioinformatics algorithms through our cloud-based software. This cloud-based distribution model results in lower revenues 
and gross profit per test than cases in which we process a test ourselves; however, because we don’t incur the costs of 
processing the tests, our costs per test under this model are also lower. We began entering into these licensing arrangements 
starting in the fourth quarter of 2015. 

74 

 
 
 
 
 
 
 
The principal focus of our commercial operations is to offer our tests through both our direct sales force and 
laboratory distribution partners, and our Constellation licensees under our cloud-based distribution model. The number of 
tests that we accession is a key indicator that we use to assess our business. A test is accessioned when we receive the test 
at our laboratory, the relevant information about the test is entered into our computer system, and the test sample is routed 
into  the  appropriate  workflow.  This  number  is  a  subset  of  the  number  of  tests  that  we  process,  which  includes  tests 
distributed through our Constellation licensees. The number of tests that we process is a key metric as it tracks overall 
volume growth, particularly as our laboratory partners may transition from sending samples to our laboratory to our cloud-
based distribution model, as a result of which our tests accessioned would decrease but our tests processed would remain 
unchanged.  

During  the  year  ended  December  31,  2020,  we  processed  approximately  1,026,500  tests,  comprised  of 
approximately 974,400 tests accessioned in our laboratories, compared to December 31, 2019, in which we processed 
approximately 804,300 tests, comprised of approximately 753,800 tests accessioned in our laboratories, and approximately 
668,600 tests processed during the year ended December 31, 2018, comprised of approximately 625,900 tests accessioned 
in our laboratories. This increase in volume represents continuous commercial growth of Panorama and HCS, both as tests 
performed in our laboratories as well as through our Constellation software platform. 

The percent of our revenues attributable to our U.S. direct sales force were 87%, 80%, and 83% for the years 
ended  December  31,  2020,  2019,  and  2018,  respectively.  The  percent  of  our  revenues  attributable  to  U.S.  laboratory 
partners for the year ended December 31, 2020 was 7%, which was up from 6% and 5%, when compared to the years 
ended December 31, 2019 and 2018. The percent of our revenues attributable to international laboratory partners and other 
international sales for the years ended December 31, 2020 was 6%, down from 14% and 12% for the years ended December 
31, 2019 and December 31, 2018, respectively. 

For  the year  ended December  31,  2020,  total  revenues were $391.0  million,  compared  to $302.3  million  and 
$257.7 million in the years ended December 31, 2019 and 2018, respectively. Product revenues generated from our testing 
accounted for $367.2 million or 94% of total revenues for the year ended December 31, 2020; $269.9 million or 89% of 
total revenues for the year ended December 31, 2019; and $240.4 million or 93% of total revenues for the year ended 
December 31, 2018. For the years ended December 31, 2020, 2019, and 2018, there were no customers exceeding 10% of 
the  total  revenues  on  an  individual  basis.  Revenues  from  customers  outside  the  United  States  were  $25.3 million, 
representing 6% of total revenues for the year ended December 31, 2020. For the years ended December 31, 2019 and 
2018, revenues from customers outside the United States were $41.5 million and $31.7 million, representing approximately 
14% and 12%, respectively, of total revenues. 

Our net losses for the years ended December 31, 2020, 2019, and 2018 were $229.7 million, $124.8 million, and 
$128.2  million, respectively. This  included non-cash  stock  compensation  expense of $50.2  million, $28.6 million,  and 
$14.2  million  for  the  years  ended  December  31,  2020,  2019,  and,  respectively.  As  of  December  31,  2020,  we  had  an 
accumulated deficit of $929.3 million. 

COVID-19 Impact 

The COVID-19 pandemic continues to present a global public health and economic challenge and is affecting 
our  business  operations  and  the  U.S.  and  other  major  economies  and  financial  markets.  The  spread  of COVID-19 has 
caused us to modify our business practices (including employee travel, mandating that all non-essential personnel work 
from home, temporary closures of our offices, and cancellation of physical participation in sales activities, meetings, events 
and conferences), and incur additional operating costs, and we may take further actions as may be required by government 
authorities or that we determine are in the best interests of our employees, customers and business partners. Such actions 
could also impact our ability to fully integrate businesses we may acquire in the future. There is no certainty that such 
actions will be sufficient to mitigate the risks posed by the virus or otherwise be satisfactory to government authorities. If 
significant portions of our workforce, and particularly our laboratory staff, are unable to work effectively, including due 
to  illness,  quarantines,  social  distancing,  government  actions  or  other  restrictions  in  connection  with  the COVID-
19 pandemic, our operations will be impacted. 

75 

  
 
 
 
 
 
The extent to which the COVID-19 pandemic impacts our business, results of operations and financial condition 
will depend on future developments, which remain highly uncertain and cannot be predicted, including, but not limited to, 
the continued duration and spread of the pandemic, its severity, the actions to contain the virus or address its impact, and 
when and to what extent normal economic and operating activities can resume. The COVID-19 pandemic could limit the 
ability of our customers, suppliers and business partners to perform under their contracts with us, including third-party 
payers’ ability to make timely payments to us during and following the pandemic. We may also experience a shortage of 
laboratory supplies and reagents or a suspension of services from other laboratories or third parties. We have also become 
increasingly dependent on growing and maintaining a network of mobile phlebotomy specialists who can provide testing 
capabilities, as many consumers are unable to visit clinics, hospitals or other testing facilities as a result of the COVID-19 
pandemic. Even after the COVID-19 pandemic has subsided, we may continue to experience an adverse impact to our 
business because of its global economic impact, including any recession that has occurred or may occur in the future. 

Specifically, difficult macroeconomic conditions as a result of COVID-19, such as decreases in per capita income 
and level of disposable income, increased and prolonged unemployment, a decline in consumer confidence, as well as 
limited or significantly reduced points of access of our products, could have a material adverse effect on the demand for 
some of our products, such as our products targeted for the IVF market. Decreased demand for our tests, particularly in 
the  United  States,  could  negatively  affect  our  overall  financial  performance.  A  significant  portion  of  our  revenue  is 
concentrated  in  the  United  States,  where  the  impact  of  COVID-19  has  been  significant,  and  the  potential  decrease  in 
demand for our tests could have a disproportionately negative impact on our business and financial results. 

Our test volumes in 2020 increased from the previous year, however, test volumes may by adversely impacted 
by the COVID-19 pandemic. The average selling price of our genetic tests in 2020 increased compared to the prior year 
which resulted in a positive impact to the results of operations. We cannot predict volatility of the volumes and selling 
prices of our genetic tests. In response to the COVID-19 pandemic, we have implemented measures to protect the health 
of our employees and to support the functionality of our laboratories. We will continue to support and incur expenditures 
towards COVID-19 prevention and employee safety. 

Components of the Results of Operations 

The section of this Management’s Discussion and Analysis generally discusses year-to-year comparisons between 
2020 and 2019. Discussions of year-to-year comparisons between 2019 and 2018 that are not included in this Annual 
Report on Form 10-K can be found in “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations” in Item 7 of Part II of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, filed 
with the SEC on March 2, 2020. 

Revenues 

Product Revenues 

We generate revenues from the sale of our tests, primarily from the sale of our Panorama and HCS tests. Our two 
primary distribution channels are our direct sales force and our laboratory partners. In cases where we promote our tests 
through our direct sales force, we generally bill directly to a patient, clinic or insurance carrier, or a combination of the 
insurance carrier and patient for the fees. 

Sales  of  our  Panorama,  HCS,  Vistara,  Anora,  Spectrum,  Signatera  CLIA,  and  Prospera  tests  are  recorded  as 
product  revenues.  Revenues  recognized  from  tests  processed  through  our  Constellation  model,  from  the  Qiagen,  BGI 
Genomics,  and  Foundation  Medicine  agreements  (collectively  the  “Strategic  Partnership  Agreements”),  and  from  our 
Signatera research use only (“RUO”) offering are reported in licensing and other revenues. 

In cases where we sell our tests through our laboratory partners, the majority of our laboratory partners bill the 
patient, clinic or insurance carrier for the performance of our tests, and we are entitled to either a fixed price per test or a 
percentage of their collections.  

76 

 
 
 
 
 
 
 
Our ability to increase our revenues will depend on our ability to further penetrate the domestic and international 
markets and, in particular, generate sales through our direct sales force, develop and commercialize additional tests, obtain 
reimbursement from additional third-party payers and increase our reimbursement rate for tests performed. In particular, 
our financial performance depends on reimbursement for Panorama in the average risk population and for microdeletions. 
There has been a significant increase in the number of commercial third-party payers that cover the use of Panorama in 
the average risk population, representing approximately 95% of commercial covered lives in the United States, as well as 
an increasing number of state Medicaid payers expanding coverage to average risk pregnancies. Many third-party payers 
do not currently reimburse for microdeletions screening, as further discussed in the risk factor entitled “Reimbursement 
and Regulatory Risks Related to Our Business— If we are unable to expand or maintain third-party payer coverage and 
reimbursement for Panorama and our other tests, or if we are required to refund any reimbursements already received, 
our revenues and results of operations would be adversely affected,” in part because there is currently limited published 
data  on  the  performance  of  microdeletions  screening  tests.  A  new  current  procedure  terminology  (“CPT”)  code  for 
microdeletions went into effect beginning January 1, 2017. We have experienced low average reimbursement rates thus 
far for microdeletions testing under this new code, and we expect that this new code will cause, at least in the near term, 
our microdeletions reimbursement to remain low, due to third-party payers declining to reimburse and through reduced 
reimbursement  under  the  new  code.  This  has  had,  and  we  expect  it  will  continue  to  have,  an  adverse  impact  on  our 
revenues. In addition, a new CPT code for expanded carrier screening went into effect beginning January 1, 2019, and has 
had, and may continue to have, an adverse effect on our reimbursement rates for our broader Horizon carrier screening 
panel for which we previously primarily received reimbursement on a per-condition basis, as those tests may be reimbursed 
as a combined single panel instead of as multiple individual tests. Because our revenues from Horizon continue to represent 
an increasing proportion of our overall revenues, a decline in our reimbursement rates for, and therefore our average selling 
price of, Horizon, could result in a decline in our overall revenue. 

Our financial performance has also been impacted by our larger in-network coverage with third-party payers, 
which we believe is crucial to our growth and long-term success. However, because the negotiated fees under our contracts 
with third-party payers are typically lower than the list price of our tests, as we enter into additional in-network contracts 
with  insurance  providers,  our  average  reimbursement  per  test  may  decrease  as  compared  to  out-of-network  contracts. 
While we expect the reduction in average reimbursement per test from in-network pricing to reduce our revenues and gross 
margins in the near term, in-network pricing is more predictable than out-of-network pricing, and we intend to continue to 
mitigate the impact by driving more business from our most profitable accounts. 

Licensing and Other Revenues 

We also recognize licensing revenues through the licensing and the provisioning of services to support the use of 
our  proprietary  technology  by  licensees  under  our  cloud-based  distribution  model.  As  of  December  31,  2020,  we  are 
recognizing revenues on 15 licensing and service arrangements with laboratories under our Constellation model. 

Our strategy to offer our tests to laboratory licensees via our Constellation cloud-based software platform may 
also cause our revenues to decrease because we do not process the tests and perform the molecular biology analysis in our 
own laboratory under this model, and therefore are not able to charge as high an amount, and as a result realize lower 
revenues per test than when we perform the entire test ourselves. However, cost of licensing and other revenues for the 
Constellation software platform are relatively low, and therefore, its associated gross margin is higher. 

Cost of Product Revenues  

The components of our cost of product revenues are material and service costs, impairment charges associated 
with  testing  equipment,  personnel  costs,  including  stock-based  compensation  expense,  equipment  and  infrastructure 
expenses  associated  with  testing  samples,  electronic  medical  records,  order  and  delivery  systems,  shipping  charges  to 
transport samples, costs incurred from third party test processing fees, and allocated overhead such as rent, information 
technology costs, equipment depreciation and utilities. Costs associated with Whole Exome Sequencing (“WES”) are also 
included,  as  well  as  labor  costs,  relating  to  our  Signatera  CLIA  offering.  Costs  associated  with  performing  tests  are 
recorded when the test is accessioned. We expect cost of product revenues in absolute dollars to increase as the number of 
tests we perform increases. 

77 

 
 
 
 
 
 
As we continue to achieve scale, we have increased our focus on more efficient use of labor, automation, and 
DNA sequencing. For example, we updated the molecular and bioinformatics process for Panorama to further reduce the 
sequencing reagents, test steps and associated labor costs required to obtain a test result, while increasing the accuracy of 
the test to allow it to run with lower fetal fraction input. These improvements also reduced the frequency of the need to 
require blood redraws from the patient. 

Cost of Licensing and Other Revenues 

The components of our cost of licensing and other revenues are material costs associated with test kits sold to 
Constellation  clients,  development  and  support  services  relating  to  our  Strategic  Partnership  Agreements,  and  costs 
associated with specimens and Whole Exome Sequencing (“WES”), as well as labor costs, relating to our Signatera (RUO) 
offering. 

We  currently  have  15  revenue  generating  licensing  and  service  agreements  with  laboratories  under  our 
Constellation  distribution  model.  We  consider  our  cost  of  licensing  and  other  revenues  for  the  Constellation  software 
platform to be relatively low, and therefore we expect its associated gross margin is higher. We expect our cost of licensing 
will increase in relation to volume growth. 

Research and Development  

Research and development expenses include costs incurred to develop our technology, collect clinical samples 
and conduct clinical studies to develop and support our products. These costs consist of personnel costs, including stock-
based  compensation  expense;  prototype  materials;  laboratory  supplies;  consulting  costs;  regulatory  costs;  electronic 
medical  record  set  up  costs;  and  costs  associated  with  setting  up  and  conducting  clinical  studies  at  domestic  and 
international sites and allocated overhead, including rent, information technology, equipment depreciation and utilities. 
We expense all research and development costs in the periods in which they are incurred. We expect our research and 
development  expenses  to  increase  in  absolute  dollars  as  we  continue  to  invest  in  research  and  development  activities 
related to developing enhanced and new products.  

Selling, General and Administrative  

Selling,  general  and  administrative  expenses  include  executive,  selling  and  marketing,  legal,  finance  and 
accounting, human resources, billing and client services. These expenses consist of personnel costs, including stock-based 
compensation  expense;  direct  marketing  expenses;  audit  and  legal  expenses;  consulting  costs;  training  and  medical 
education activities; payer outreach programs and allocated overhead, including rent, information technology, equipment 
depreciation, and utilities.  

Gain on Disposal of Business 

In September 2019, we sold our Evercord business that provided cord tissue processing and storage services for 
total estimated consideration of $15.4 million, including $9.7 million in cash, $1.0 million of cash deposited in a third-
party escrow account recorded in short-term other receivables, and $4.7 million of additional consideration. We recognized 
a gain of $14.4 million on the sale, which was included in loss from operations in the consolidated statements of operations 
and comprehensive loss. 

Interest Expense  

Interest  expense  is  attributable  to  borrowing  under  our  Credit  Line,  the  2017  Term  Loan,  as  well  as  the 

Convertible Note, including the amortization of debt discounts.  

78 

 
 
 
 
 
 
 
 
 
 
Interest Income and Other (Expense) Income, Net  

Interest income and other (expense) income, net is comprised of interest earned on our cash, realized gains and 
losses on investments, foreign currency remeasurement gains and losses, changes in the fair value of our warrants, and 
finance charges related to the unused borrowing capacity of our 2017 Term Loan.  

Loss on Debt Extinguishment 

The loss on debt extinguishment of $5.8 million was a result of the repayment of the outstanding principal and 

interest under the 2017 Term Loan with Orbimed in the second quarter of 2020. Refer to note 10, Debt, for details. 

Critical Accounting Policies 

Our management’s discussion and analysis of our financial condition and results of operations is based on our 
financial statements, which have been prepared in accordance with generally accepted accounting principles in the United 
States. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported 
amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, 
as well as the reported revenue generated, and expenses incurred during the reporting periods. 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. We consider 
our  critical  accounting  policies  and  estimates  to  be  revenue  recognition,  leases,  inventory,  fair  value  measurements 
including  the  valuation  of 2.25%  Convertible  Senior  Notes  due  2027  (the  “Convertible  Notes”),  and  stock-based 
compensation. 

Recent Accounting Pronouncements 

There  are  no  recent  accounting  pronouncements  that  have  a  material  impact  to  our  consolidated  financial 

statements. See Note 2, Summary of Significant Accounting Policies, for recently adopted accounting pronouncements. 

Revenue Recognition 

We recognize revenues when, or as, performance obligations in the contracts are satisfied, in the amount reflecting 

the expected consideration to be received from the goods or services transferred to the customers. 

Product Revenues 

Product  revenues  are  derived  from  contracts  with  insurance  carriers,  laboratory  partners  and  patients  in 
connection  with  sales  of  prenatal  genetic  and  other  diagnostics  tests.  The  majority  of  our  revenues  are  derived  from 
Panorama NIPT, HCS, and to a lesser extent, other genetic tests including Signatera CLIA and Prospera. We enter into 
contracts with insurance carriers with primarily payment terms related to tests provided to the patients who have health 
insurance coverage. Insurance carriers are considered to be third-party payers on behalf of the patients, and the patients 
are considered as the customers who receive genetic test services. Tests may be billed to insurance carriers, patients, or a 
combination of insurance carriers and patients. Further, we sell tests to a number of domestic and international laboratory 
partners and identify the laboratory partners as customers provided that there is a test services agreement between us and 
them. 

Licensing and Other Revenues 

We recognize licensing revenues from our Constellation cloud-based distribution model, pursuant to which we 
grant  licenses  to  laboratories  to  access  our  proprietary  bioinformatics  algorithms  through  our  cloud-based  software  to 
analyze the results of molecular workflows that such licensees perform in their laboratories. In addition, the royalties we 
receive from our arrangement with a prenatal paternity licensee are recognized Constellation revenues. 

79 

 
 
 
 
 
 
We  also  recognize  revenues  from  our  Signatera  (RUO)  offering,  which  is  for  research  use  only  to  cancer 
researchers and biopharmaceutical companies. We enter into agreements with pharmaceutical companies to utilize our 
Signatera  tests  typically  to  study  new  cancer  treatments  or  to  validate  the  outcomes  of  clinical  trials  for  which  the 
pharmaceutical companies are identified as customers. 

We also recognize revenues from our Strategic Partnership Agreements. The performance obligations are unique 
in each agreement and would typically require the license of intellectual property, development services, support services, 
and future test work. We also record revenues from the sale of IVD kits in licensing and other revenues. 

Income Taxes  

We  account  for  income  taxes  in  accordance  with  ASC  740, Income  Taxes (“ASC 740”),  which  requires 
recognition of deferred tax assets and liabilities for the expected tax consequences of our future financial and operating 
activities. Under ASC 740, we determine deferred tax assets and liabilities based on the temporary difference between the 
financial statement and tax bases of assets and liabilities using the tax rates in effect for the year in which we expect such 
differences to reverse.  If we determine that it is more likely than not that we will not generate sufficient taxable income 
to realize the value of some or all of our deferred tax assets (net of our deferred tax liabilities), we establish a valuation 
allowance offsetting the amount we do not expect to realize.  We perform this analysis each reporting period and reduce 
our measurement of deferred taxes, if the likelihood we will realize them becomes uncertain.   

We also account for uncertain tax positions in accordance with ASC 740, which requires us to adjust our financial 
statements to reflect only those tax positions that are more-likely-than-not to be sustained upon review by federal or state 
examiners.  We  may  recognize  a  tax  benefit  only  if  it  is  more  likely  than  not  the  tax  position  will  be  sustained  on 
examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the 
financial  statements  from  such  positions  are  then  measured  based  on  the  largest  benefit  that  has  a  greater  than  50% 
likelihood of being realized upon settlement. We established a full valuation allowance against its net deferred tax assets 
in 2020 and 2019 due to the uncertainty surrounding realization of these assets (for details, please refer to Note 14, Income 
Taxes).  In  addition,  our  policy  is  to  report  interest  and  penalties  related  to  unrecognized  tax  benefits  as  income  tax 
expenses.  

Stock-Based Compensation 

We have included stock-based compensation as part of our cost of revenues and our operating expenses in our 

statements of operations as follows:

Stock-based compensation related to stock options granted to our employees and non-employees is measured at 
the grant date based on the fair value of the award, which is determined by the Black-Scholes option-pricing model and 
the Monte Carlo simulation model. The fair value is recognized as expense over the requisite service period, which is 
generally the vesting period of the respective awards. No compensation cost is recognized on stock options for employees 
and  non-employees  who  do  not  render  the  requisite  service  and  therefore  forfeit  their  rights  to  the  stock  options.  The 
measurement of stock-based compensation is subject to periodic adjustments as the underlying equity instruments vest,

and the resulting change in value, if any, is recognized in our statements of operations and comprehensive loss during the 
period that the related services are rendered. 

Impairment of Long-Lived Assets 

We evaluate our long-lived assets for indicators of possible impairment when events or changes in circumstances 
indicate the carrying amount of an asset may not be recoverable. We then compare the carrying amounts of the assets with 
the future net undiscounted cash flows expected to be generated by such asset. Should an impairment exist, the impairment 
loss  would  be  measured  based  on  the  excess  carrying  value  of  the  asset  over  the  asset’s  fair  value  determined  using 
discounted estimates of future cash flows. There were no asset impairment charges for the year ended December 31, 2020.  

For the year ended December 31, 2019, an asset impairment charge of $1.7 million was recorded in general and 
administrative expenses in the statements of operations and comprehensive loss. This charge is comprised of $1.2 million 
from the impairment of leasehold improvements, $0.1 million from the impairment of capitalized software held for internal 
use, and $0.4 million from the right-of-use asset related to the disposal of business. The right-of-use asset and the leasehold 
improvements relate to the storage facility located in Tukwila, Washington, and both assets were evaluated for impairment 
as  a  single  asset  group.  Subsequent  to  the  sale  of  Evercord,  we  recognized  an  impairment  charge  for  the  leasehold 
improvements that was previously capitalized for the storage facility and wrote down the right-of-use asset to its fair value 
as of the sale date.

Revenues 

Total revenues are comprised of product revenues, which are primarily driven by sales of our Panorama and HCS 
tests,  and  licensing  and  other  revenues,  which  primarily  includes  development  licensing  revenue,  licensing  of  our 
Constellation software to our licensees, and revenues from our Signatera (RUO) offering. Total revenues increased by 
$88.7 million, or 29%, when compared to the year ended December 31, 2019. 

We derive our revenues from tests based on units reported to customers—tests delivered with a result. All reported 
units  are  either  accessioned  in  our  laboratories  or  processed  outside  of  our  laboratories.  As  noted  in  “Overview,”  the 
number of tests that we process is a key metric as it tracks overall volume growth. During the year ended December 31, 
2020,  total  reported  units  were  approximately  962,400,  comprised  of  approximately  912,500  tests  reported  in  our 
laboratories. Comparatively, during the year ended December 31, 2019, total reported units were approximately 763,900, 
comprised of approximately 718,500 tests reported in our laboratories. 

Product Revenues 

During the year ended December 31, 2020, product revenues increased by $97.3 million, or 36% compared to the 

year ended December 31, 2019, as a result of the continued revenue growth from test volumes. 

Licensing and Other Revenues 

Licensing  and  other  revenues  decreased  by  $8.7  million,  or  27%,  during  the  year  ended  December  31,  2020 
compared to the year ended December 31, 2019. The decrease in revenue was primarily due to a $6.1 million decrease 
from the Evercord offering due to the sale of this business in the third quarter of 2019. The remaining decrease of a net 
$2.6 million was primarily related to a decrease in revenues recognized from our collaborative agreements partially offset 
by increased revenues from our oncology offering. 

Cost of Product Revenues 

During the year ended December 31, 2020, cost of product revenues increased by $23.3 million or 14% when 
compared to the year ended December 31, 2019, primarily due to higher costs related to inventory consumption of $18.1 
million driven by an increase in accessioned cases, higher labor and overhead costs of approximately $11.0 million driven 
by  headcount  growth,  product  support,  our  HCS  automation  workflow,  and  COVID-19  related  costs  (e.g.,  virus 
preventative supplies, hazard pay, and salary increases for essential workers) partially offset by a net decrease of $5.8 
million in specimen related fees primarily related to cost savings from our HCS automation workflow. 

Cost of Licensing and Other Revenues 

Cost of licensing and other revenues for the year ended December 31, 2020, when compared to the year ended 
December  31,  2019,  increased  by  $4.9  million,  or  38%,  primarily  due  to  an  increase  in  costs  to  satisfy  performance 
obligations for our oncology offering and collaboration agreements of a net $8.3 million. This was offset by a decrease of 
$3.4 million in cost related to the Evercord offering as we stopped offering this service during the third quarter of 2019. 

Research and Development 

Research and development expenses during the year ended December 31, 2020 increased by $48.7 million, or 
95%, when compared to the year ended December 31, 2019. The increase was primarily driven by $30.8 million of higher 
salary and related expenditures due primarily to headcount growth, which include a $6.1 million increase in stock-based 
compensation expense. In addition, there was an increase of $6.4 million of consulting costs and $9.5 million of costs 
related  to  clinical  studies  from  our  new  product  offerings,  and  a  $2.0  million  increase  related  to  software  licenses, 
production support, and other expenses.

Selling, General and Administrative 

Selling, general and administrative expenses increased by $97.5 million, or 47%, in the year ended December 31, 
2020 compared to the year ended December 31, 2019. The increase was primarily attributable to an increase of $73.1 
million of higher salary and related expenditures due primarily to headcount growth, which include a $14.7 million increase 
in stock-based compensation expense, $12.7 million in additional consulting and legal fees, $6.3 million for increased 
marketing  expenses,  $4.8  million  from  increased  business  insurance  costs,  and  $4.7  million  of  higher  costs  related  to 
computer hardware, office supplies and other expenses. This was partially offset by a $4.1 million decrease in travel related 
costs due to restrictions from the COVID-19 pandemic. 

Gain on Disposal of Business 

Gain on disposal of business was $14.4 million in the year ended December 31, 2019 due to the gain on sale of 

Evercord. There was no such gain during the year ended December 31, 2020. 

Interest Expense  

Interest expense increased by $4.4 million, 41%, in the year ended December 31, 2020 compared to the same 
period in the prior year. The increase was primarily due to the issuance of the Convertible Notes in April 2020 with an 
outstanding principal balance of $287.5 million at a 2.25% interest rate (refer to note 10, Debt, for additional information). 

Interest and Other Income  

Interest and other income increased by $3.4 million, or 82%, in the year ended December 31, 2020, compared to 
the same period in the prior year, primarily due to additional interest income of $1.2 million from larger cash and cash 
equivalent and investments balances, and sublease and other income of $2.2 million. 

Loss on Debt Extinguishment 

The loss on debt extinguishment of $5.8 million was a result of the repayment of the outstanding principal and 
interest  under  the  2017  Term  Loan  with  Orbimed  in  the  third  quarter  of  2020.  Refer  to  note  10, Debt,  for  additional 
information. 

Liquidity and Capital Resources  

We have incurred net losses each year since our inception. For the year ended December 31, 2020, we had a net 
loss of $229.7 million, and we expect to continue to incur losses in future periods as we continue to devote a substantial 
portion of our resources to our research and development and commercialization efforts for our existing and new products. 
As  of  December  31,  2020,  we  had  an  accumulated  deficit  of  $929.3 million.  We  had  $48.9 million  in  cash  and  cash 
equivalents and restricted cash, $688.6 million in marketable securities, $50.1 million of outstanding balance of the Credit 
Line including accrued interest, and $287.5 million outstanding principal balance on the Convertible Notes. We used a 
portion of the net proceeds from the offering of the Convertible Notes to repay its obligations under its 2017 Term Loan 
with OrbiMed (see Note 10, Debt). 

While we have introduced multiple products that are generating revenues, these revenues have not been sufficient 
to  fund  all  operations.  Accordingly,  we  have  funded  the  portion  of  operating  costs  that  exceeds  revenues  through  a 
combination of equity issuances and debt and other financings. We expect to develop and commercialize future products 
and,  consequently,  we  will  need  to  generate  additional  revenues  to  achieve  future  profitability  and  may  need  to  raise 
additional equity or incur additional debt. If we raise additional funds by issuing equity securities, our stockholders would 
experience dilution. Additional debt financing, if available, may involve covenants restricting our operations or our ability 
to incur additional debt. Any additional debt financing or additional equity that we raise may contain terms that are not 
favorable to us or our stockholders and requires significant debt service payments, which diverts resources from other 
activities. Additional financing may not be available at all, or in amounts or on terms acceptable to us. If we are unable to 

83 

 
 
 
 
 
 
 
 
 
 
obtain additional financing, we may be required to delay the development and commercialization of our products and 
significantly scale back our business and operations. 

In April 2019, we completed an underwritten equity offering and sold 6,052,631 shares of common stock at a 
price of $19 per share to the public. Before offering expenses of $0.6 million, we received proceeds of $108.1 million net 
of the underwriting discount. In October 2019, we completed another underwritten equity offering and sold 6,571,428 
shares of its common stock at a price of $35 per share to the public. Before offering expenses of $0.4 million, we received 
proceeds of $216.2 million net of the underwriting discount. In September 2020, the Company completed an additional 
underwritten equity offering and sold 4,791,665 shares of its common stock at a price of $60.00 per share to the public. 
Before  offering  expenses  of  $0.3  million,  the  Company  received  proceeds  of  $271.0  million  net  of  the  underwriting 
discount. 

Based on our current business plan, we believe that our existing cash and marketable securities will be sufficient 

to meet our anticipated cash requirements for at least 12 months after February 25, 2021. 

Credit Line Agreement 

In September 2015, we entered into the Credit Line with UBS providing for a $50.0 million revolving line of 
credit which can be drawn in increments at any time. The Credit Line was amended in July 2017 and bears interest at 30-
day LIBOR plus 1.10%, and it is secured by a first priority lien and security interest in our money market and marketable 
securities held in our managed investment account with UBS. UBS has the right to demand full or partial payment of the 
Credit Line obligations and terminate it, in its discretion and without cause, at any time. 

2017 Term Loan 

In August 2017, we entered into the 2017 Term Loan with OrbiMed, which has a maximum borrowing capacity 
of $100.0 million. On the closing date of August 8, 2017, we borrowed $75.0 million, with the remaining $25.0 million 
available  to  borrow  at  our  option  at  any  time  through  December  31,  2019.  Subsequently,  we  entered  into  several 
amendments and extended the expiration date until December 31, 2019 to draw the unused borrowing capacity of $50.0 
million. After the amendments, the interest rate was equal to the sum of (i) 8.25% plus (ii) the higher of 1.00% or LIBOR, 
provided we draws the minimum capacity of $25.0 million. If the amount drawn is less than $25.0 million, the interest rate 
would remain at the sum of (i) 8.75% plus (ii) the higher of 1.00% or LIBOR. As a fee in consideration of extending the 
commitment to provide this option to draw until December 31, 2019, we issued an additional 25,000 shares of our common 
stock to OrbiMed. We did not exercise such option, and the right to draw the unused borrowing capacity expired. In April 
2020, we used a portion of the net proceeds from the offering of the Convertible Notes to repay our obligations under the 
2017 Term Loan with OrbiMed. 

Convertible Notes 

In April 2020, we issued $287.5 million aggregate principal amount of Convertible Notes in a private placement 

offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. 

The Convertible Notes are senior, unsecured obligations of the Company and bear interest at a rate of 2.25% per 
year, payable in cash semi-annually in arrears in May and November of each year, beginning in November 2020. The 
Convertible Notes mature in May 2027, unless earlier converted, repurchased or redeemed in accordance with their terms. 
Upon conversion, the Convertible Notes are convertible into cash, shares of our common stock or a combination of cash 
and shares of our common stock, at our election. 

We received net proceeds from the Convertible Notes of $278.3 million, after deducting the initial purchasers’ 
discounts and debt issuance costs. We used approximately $79.2 million of the net proceeds from the Convertible Notes 
offering to repay our obligations under the 2017 Term Loan with OrbiMed.

Cash Used in Operating Activities 

Cash used in operating activities during the year ended December 31, 2020 was $182.5 million. The net loss of

accretion  of  the  convertible  note,  $5.8  million  loss  on  debt  extinguishment,  and  $0.1  million  of  amortization  of  debt 
discount. These non-cash charges were offset by $0.2 million of inventory reserve adjustments, $0.1 million of gain on 
investments, and $0.2 million of non-cash benefits. Operating assets had cash outflows of $56.8 million resulting from 
$25.8 million increases in accounts receivable, $7.5 million increases in inventory, and $23.4 million decreases in prepaid 
assets, and $0.1 million increases in other assets. Operating liabilities generated cash inflows of $17.6 million resulting 
from a $10.3 million increase in other accrued liabilities, a $14.3 million increase in accrued compensation offset by $0.1 
million decrease in accounts payable and $6.9 million decrease in deferred revenue.  

Cash used in operating activities during the year ended December 31, 2019 was $63.4 million. The net loss of 
$124.8 million includes $34.2 million in non-cash benefits resulting from $7.7 million of depreciation and amortization, 
$7.7 million of amortization of the operating right-of-use assets on a straight-line basis subsequent to the adoption of ASC 
842,  $28.6 million  of  stock-based  compensation  expense;  amortization  of  debt  discount,  premium  amortization  and 
discount  accretion  on  investment  securities  totaling  $1.4  million,  $0.3  million  of  inventory  excess  adjustments,  $1.7 
million from impairment of assets, and $1.2 million in other non-cash charges. These non-cash charges were offset by 
$14.4 million gain on disposal of Evercord. Operating assets had $19.7 million cash outflow resulting from $13.9 million 
increases in prepaid and other current assets, $9.1 million increases in other assets, offset by a $2.4 million decrease in 
accounts receivable, $0.9 million decrease in inventory. Operating liabilities generated cash inflows of $46.9 million due 
to an increase of deferred revenues of $40.9 million primarily driven by prepaid license, royalties and milestone payments 
from our strategic partnership agreements, an increase in accrued compensation of $3.4 million, an increase in other long-
term liabilities of $0.3 million, and an increase in other accrued liabilities by  $8.6 million, offset by a decrease in accounts 
payable of $6.3 million.

ITEM 7A:  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

Interest Rate Risk 

We are exposed to market risks in the ordinary course of our business. These risks primarily relate to interest 
rates. Our Credit Line has an interest rate of one-month LIBOR plus 1.10%. The LIBOR rate is variable. An incremental 
change in the borrowing rate of 100 basis points would increase our annual interest expense by $0.5 million based on our 
$50.1 million gross debt outstanding on our Credit Line, including principal and accrued interest as of December 31, 2020. 
The interest rate for our Convertible Notes is fixed at 2.25% and not exposed market risk related to interest rates. Our

 investment portfolio is exposed to market risk from changes in interest rates. This risk is mitigated as we have maintained 
a relatively short average maturity for our investment portfolio. An incremental change in the investment yield of 100 
basis points would increase our annual interest income by approximately $6.9 million annually in relation to amounts we 
would expect to earn, based on our short-term investments as of December 31, 2020. 

Foreign Currency Exchange Rate Fluctuations 

Our operations are currently conducted primarily in the United States. As we expand internationally, our results 
of operations and cash flows may become subject to fluctuations due to changes in foreign currency exchange rates. In 
periods when the U.S. dollar declines in value as compared to the foreign currencies in which we incur expenses, our 
foreign-currency based  expenses will  increase  when  translated  into  U.S.  dollars.  In  addition,  future fluctuations  in the 
value of the U.S. dollar may affect the price at which we sell our tests outside the United States. To date, our foreign 
currency risk has been minimal and we have not historically hedged our foreign currency risk; however, we may consider 
doing so in the future.

Report of Independent Registered Public Accounting Firm 

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

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Natera, Inc. (the Company) as of December 31, 2020 
and 2019, and the related consolidated statements of operations and comprehensive loss, stockholders' equity and cash 
flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as 
the "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, 2020 and 2019, and the results of its operations and its 
cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted 
accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established 
in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (2013 framework) and our report dated February 25, 2021 expressed an unqualified opinion thereon. 

Basis for Opinion 

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

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

 Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements 
that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or 
disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or 
complex judgments. The communication of 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 account or disclosure to which it relates. 

  Genetic Test Revenue  

Description of the 
Matter 

  For the year ended December 31, 2020, the Company’s revenue from sales of genetic tests was 
$367.2 million. As explained in Note 3 of the consolidated financial statements, revenue from 
genetic tests is recognized upon delivery of the test results. The revenue recognized for the genetic 
tests is based on an estimate of the total consideration expected to be received for the genetic tests. 
In particular, the estimate of total consideration is affected by assumptions of reimbursement from 

88 

  
  
 
  
  
  
 
 
 
 
 
 
 patients and insurance carriers, including estimates for disallowed cases, discounts, refunds and 
doubtful accounts. 

Auditing the measurement of the Company’s genetic test revenue was complex as it requires 
significant judgement to evaluate the assumptions and inputs utilized by management in 
determining the total consideration to be received by the Company for delivered tests and the 
amounts involved are material to the financial statements taken as a whole. 

How We 
Addressed the 
Matter in Our 
Audit 

  We obtained an understanding, evaluated the design, and tested the operating effectiveness of 
internal controls that address the risks of material misstatement relating to the measurement of 
genetic test revenues. This included testing controls related to management’s review of the 
significant assumptions and inputs used in the determination of the estimated amount that would 
be collected for tests performed during the period. We also tested controls over the current and 
historical data used by management in determining this estimate, including the completeness and 
accuracy of the data.  

We performed audit procedures that included, among others, assessing methodologies and testing 
the significant assumptions discussed above and the underlying data used by the Company in its 
analysis. We compared the significant assumptions used by management to those used in prior 
periods and examined evidence regarding the changes in assumptions. We also assessed the 
historical accuracy of management’s estimates.

Natera, Inc. 
Notes to Consolidated Financial Statements 

1.    Description of Business 

Natera, Inc. (the "Company") was formed in the state of California as Gene Security Network, LLC in November 
2003 and incorporated in the state of Delaware in January 2007. The Company’s mission is to change the management of 
disease worldwide, focusing on women's health, oncology, and organ health. The Company operates laboratories certified 
under the Clinical Laboratory Improvement Amendments ("CLIA") providing a host of cell-free DNA-based molecular 
testing  services.  The  Company  determines  its  operating  segments  based  on  the  way  it  organizes  its  business  to  make 
operating decisions and assess performance. The Company operates one segment, the development and commercialization 
of molecular testing services, applying its proprietary technology in the fields of women’s health, oncology and organ 
health. The Company also has a subsidiary that operates in the state of Texas.  

The  Company's  product  offerings  include  its  Panorama  Non-Invasive  Prenatal  Test  ("NIPT")  that  screens for 
chromosomal abnormalities of a fetus as well as in twin pregnancies, typically with a blood draw from the mother; Vistara 
(“Vistara”), a single-gene mutations screening test performed to identify single-gene disorders; Horizon Carrier Screening 
("HCS") to determine carrier status for a large number of severe genetic diseases that could be passed on to the carrier’s 
children; Spectrum Pre-implantation Genetics (“Spectrum”) to evaluate embryos to identify chromosomal anomalies or 
inherited genetic conditions to improve the chances of a healthy pregnancy during an in vitro fertilization ("IVF") cycle; 
Anora Miscarriage Test to rapidly and extensively analyze fetal chromosomes to understand the cause of miscarriage; 
Non-Invasive Paternity Testing ("PAT"), which is exclusively marketed and sold by a licensee from whom the Company 
receives a royalty; Signatera, which detects circulating tumor DNA in patients previously diagnosed with cancer to assess 
molecular residual disease and monitor for recurrence; and Prospera, to assess organ transplant rejection. All testing is 
available principally in the United States. The Company also offers its Panorama test to customers outside of the United 
States,  primarily  in  Europe.  The  Company  also  offers  Constellation,  a  cloud-based  software  platform  that  enables 
laboratory customers to gain access through the cloud to the Company’s algorithms and bioinformatics in order to validate 
and launch tests based on the Company’s technology. Through the third quarter of 2019, the Company offered Evercord 
for the collection and storage of newborn cord blood and cord tissue units, which was sold in the third quarter of 2019 to 
a third-party buyer. 

2.    Summary of Significant Accounting Policies 

Basis of Presentation 

The  accompanying  consolidated  financial  statements  have  been  prepared  in  conformity  with  U.S.  generally 

accepted accounting principles (“U.S. GAAP”). 

Liquidity Matters 

The Company has incurred net losses since its inception and anticipates net losses and negative operating cash 
flows for the near future. For the year ended December 31, 2020, the Company had a net loss of $229.7 million and an 
accumulated deficit to $929.3 million. At December 31, 2020, the Company had $48.9 million in cash, cash equivalents 
and restricted cash, $688.6 million in marketable securities, $50.1 million of outstanding balance of the Credit Line (as 
defined  in  Note  10)  including  accrued  interest,  and  $287.5  million  outstanding  principal  balance  of  the  its  2.25% 
Convertible Senior Notes (the “Convertible Notes”). The Company used a portion of the net proceeds from the offering of 
the Convertible Notes to repay its obligations under its 2017 Term Loan with OrbiMed (see Note 10, Debt). 

While the Company has introduced multiple products that are generating revenues, these revenues have not been 
sufficient to fund all operations. Accordingly, the Company has funded the portion of operating costs that exceeds revenues 
through a combination of equity issuances, debt issuances, and other financings. 

94 

 
 
 
 
 
 
 
 
The Company continues to develop and commercialize future products and, consequently, it will need to generate 
additional revenues to achieve future profitability and may need to raise additional equity or debt financing. If the Company 
raises additional funds by issuing equity securities, its stockholders will experience dilution. Additional debt financing, if 
available,  may  involve  covenants  restricting  its  operations  or  its  ability  to  incur  additional  debt.  Any  additional  debt 
financing or additional equity that the Company raises may contain terms that are not favorable to it or its stockholders 
and requires significant debt service payments, which diverts resources from other activities. Additional financing may 
not be available at all, or in amounts or on terms acceptable to the Company. If the Company is unable to obtain additional 
financing, it may be required to delay the development and commercialization of its products and significantly scale back 
its business and operations. 

In April 2019, the Company completed an underwritten equity offering and sold 6,052,631 shares of its common 
stock at a price of $19 per share to the public. Before offering expenses of $0.6 million, the Company received proceeds 
of $108.1 million net of the underwriting discount. In October 2019, the Company completed another underwritten equity 
offering and sold 6,571,428 shares of its common stock at a price of $35 per share to the public. Before offering expenses 
of $0.4 million, the Company received proceeds of $216.2 million net of the underwriting discount. In September 2020, 
the Company completed an additional underwritten equity offering and sold 4,791,665 shares of its common stock at a 
price of $60.00 per share to the public. Before offering expenses of $0.3 million, the Company received proceeds of $271.0 
million net of the underwriting discount. Based on the Company’s current business plan, the Company believes that its 
existing cash and marketable securities will be sufficient to meet its anticipated cash requirements for at least 12 months 
after February 25, 2021. 

Principles of Consolidation 

The accompanying consolidated financial statements include all the accounts of the Company and its subsidiary. 
The  Company  established  a  subsidiary  that  operates  in  the  state  of  Texas  to  support  the  Company’s  laboratories  and 
operational functions. All intercompany balances and transactions have been eliminated. 

Use of Estimates 

The preparation of financial statements in accordance with generally accepted accounting principles (GAAP) in 
the United States requires management to make estimates and assumptions about future events that affect the amounts of 
assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and 
expenses. Significant items subject to such estimates include the allowance for doubtful accounts based on the assessment 
of the collectability of customer accounts, the operating right-of-use assets and the associated lease liabilities, deferred 
revenues associated with unsatisfied performance obligations, accrued liability for potential refund requests, the valuation 
of the Convertible Notes, stock-based compensation and the related valuation of equity awards, income tax uncertainties, 
and the expected consideration to be received from contracts with customers. These estimates and assumptions are based 
on  management's  best  estimates  and  judgment.  Management  regularly  evaluates  its  estimates  and  assumptions  using 
historical experience and other factors, including contractual terms and statutory limits; however, actual results could differ 
from these estimates and could have an adverse effect on the Company's financial statements. 

Cash and Cash Equivalents 

Cash and cash equivalents consist of cash and money market deposits with financial institutions. 

Restricted Cash 

Restricted cash is currently presented as a separate line item in the Company’s balance sheet. In the statements 
of cash flows, it is included together with cash and cash equivalents and considered as part of the total ending cash balance. 
The following is the reconciliation between how restricted cash is presented in the balance sheet and the statements of 
cash flows for all periods presented:

Investments 

Investments  consist  primarily  of  debt  securities  such  as  U.S.  Treasuries,  U.S.  agency  and  municipal  bonds. 
Management  determines  the  appropriate  classification  of  securities  at  the  time  of  purchase  and  re-evaluates  such 
determination at each balance sheet date. The Company generally classifies its entire investment portfolio as available-
for-sale. The Company views its available-for-sale portfolio as available for use in current operations. Accordingly, the 
Company classifies all investments as short-term, irrespective of maturity date. Available-for-sale securities are carried at 
fair value, with unrealized gains and losses reported in accumulated other comprehensive income (loss), which is a separate 
component of stockholders’ equity. 

Fair Value 

The Company discloses the fair value of financial instruments for financial assets and liabilities for which the 
value is practicable to estimate. Fair value is defined as the price that would be received upon the sale of an asset or paid 
to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). 

Risk and Uncertainties 

The Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. The extent of the impact 
of the COVID-19 pandemic on the Company's business is highly uncertain and difficult to predict, and the full extent and 
duration of the impact of the COVID 19 pandemic on our business, our operations, and the global economy as a whole is 
not yet known. While the Company’s test volumes as well as overall average selling prices increased in the year ended 
December 31, 2020 compared to the year ended December 31, 2019, the Company cannot predict the potential nature, 
magnitude and duration of the effects of the COVID-19 pandemic on the macroeconomic environment. 

Financial instruments that potentially subject the Company to credit risk consist of cash, accounts receivable and 
investments. The Company limits its exposure to credit loss by placing its cash in financial institutions with high credit 
ratings. The Company's cash may consist of deposits held with banks that may at times exceed federally insured limits. 
The Company performs evaluations of the relative credit standing of these financial institutions and limits the amount of 
credit exposure with any one institution. 

The Company performs evaluations of financial conditions for insurance carriers, patients, clinics and laboratory 
partners and generally does not require collateral to support credit sales. For the years ended December 31, 2020, 2019, 
and 2018, there were no customers exceeding 10% of total revenues on an individual basis. As of December 31, 2020 and 
2019, there were no customers with an outstanding balance exceeding 10% of net accounts receivable. 

Credit Losses 

Trade accounts receivable and other receivables. The allowance for doubtful accounts is based on the Company’s 
assessment  of  the  collectability  of  customer  accounts.  The  Company  regularly  reviews  the  allowance  by  considering 
factors such as historical experience, credit quality, the age of the accounts receivable balances, and current economic 
conditions that may affect a customer’s ability to pay. 

The following is a roll-forward of the allowances for credit losses related to trade accounts receivable and other 

receivables for the year ended December 31, 2020:

Available-for-sale  debt  securities. The  amended  guidance  from  ASU  2016-13  requires  the  measurement  of 
expected  credit  losses for  available-for-sale debt  securities held  at  the  reporting  date  over  the  remaining  life  based  on 
historical experience, current conditions, and reasonable and supportable forecasts. The Company evaluated its investment 
portfolio under the new available-for-sale debt securities impairment model guidance. The vast majority of the Company’s 
investment portfolio are low risk, investment grade securities. 

Revenue Recognition 

The Company adopted the new revenue recognition guidance, ASC 606, beginning January 1, 2018 on a full 

retrospective basis. ASC 606 mandates revenue recognition to be evaluated using the following five steps: 

Identification of a contract, or contracts, with a customer; 
Identification of the performance obligations in the contract; 

• 
• 
•  Determination of the transaction price; 
•  Allocation of the transaction price to the performance obligations in the contract; and 
•  Revenue recognition when, or as, the performance obligations are satisfied 

See Note 3, Revenue Recognition, for detailed discussions of product revenues, licensing and other revenues, and 

how the five steps described above are applied. 

Cost of Product Revenues 

The components of our cost of product revenues are material and service costs, impairment charges associated 
with  testing  equipment,  personnel  costs,  including  stock-based  compensation  expense,  equipment  and  infrastructure 
expenses  associated  with  testing  samples,  electronic  medical  records,  order  and  delivery  systems,  shipping  charges  to 
transport samples, costs incurred from third party test processing fees, and allocated overhead such as rent, information 
technology costs, equipment depreciation and utilities. Costs associated with Whole Exome Sequencing (“WES”) are also 
included,  as  well  as  labor  costs,  relating  to  our  Signatera  CLIA  offering.  Costs  associated  with  performing  tests  are 
recorded when the test is accessioned. We expect cost of product revenues in absolute dollars to increase as the number of 
tests we perform increases. 

 However, having rapidly achieved scale, we have increased our focus on more efficient use of labor, automation, 
and DNA sequencing. For example, we updated the molecular and bioinformatics process for Panorama to further reduce 
the sequencing reagents, test steps and associated labor costs required to obtain a test result, while increasing the accuracy 
of the test to allow it to run with lower fetal fraction input. These improvements also reduced the frequency of the need to 
require blood redraws from the patient. 

Cost of Licensing and Other Revenues  

The components of our cost of licensing and other revenues are material costs associated with test kits sold to 
Constellation  clients,  development  and  support  services  relating  to  our  Strategic  Partnership  Agreements,  and  costs 
associated with specimens and Whole Exome Sequencing (“WES”), as well as labor costs, relating to our Signatera (RUO) 
offering. 

97 

 
 
 
 
 
     
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  currently  have  15  revenue  generating  licensing  and  service  agreements  with  laboratories  under  our 
Constellation  distribution  model.  We  consider  our  cost  of  licensing  and  other  revenues  for  the  Constellation  software 
platform to be relatively low, and therefore we expect its associated gross margin is higher. We expect our cost of licensing 
will increase in relation to volume growth. 

Research and Development  

The Company records research and development costs in the period incurred. Research and development costs 
consist  of  personnel  costs,  contract  services,  cost  of  materials  utilized  in  performing  tests,  costs  of  clinical  trials  and 
allocated facilities and related overhead expenses.  

Advertising Costs  

The Company expenses advertising costs as incurred. The Company incurred advertising costs of $0.6 million, 

$0.2 million, and $0.2 million for the years ended December 31, 2020, 2019, and 2018, respectively. 

Product Shipment Costs  

The Company expenses product shipment costs in cost of product revenues in the accompanying statements of 
operations. Shipping and handling costs for the years ended December 31, 2020, 2019, and 2018 were $13.3 million, $13.3 
million, and $12.4 million, respectively. 

Income Taxes  

Income taxes are recorded in accordance with Financial Accounting Standards Board ASC Topic 740, Income 
Taxes  ("ASC  740"),  which  provides  for  deferred  taxes  using  an  asset  and  liability  approach.  Deferred  tax  assets  and 
liabilities  are  recognized  for  the  future  tax  consequences  attributable  to  differences  between  the  financial  statement 
carrying amounts of existing assets and liabilities and their respective tax bases using enacted tax rates in effect for the 
year in which the differences are expected to affect taxable income. Tax benefits are recognized when it is more likely 
than not that a tax position will be sustained during an audit. Deferred tax assets are reduced by a valuation allowance if 
current evidence indicates that it is considered more likely than not that these benefits will not be realized. 

Stock-Based Compensation 

Stock-based compensation related to stock options and restricted stock units (“RSUs”) granted to the Company’s 
employees is measured at the grant date based on the fair value of the award. The fair value is recognized as expense over 
the  requisite  service  period,  which  is  generally  the  vesting  period  of  the  respective  awards.  No  compensation  cost  is 
recognized when the requisite service has not been met and the awards are therefore forfeited. 

For stock options with market conditions, the Company derives the requisite service period using the Monte Carlo 
simulation model. For stock options and RSUs that vest upon meeting performance conditions or market conditions in 
combination with performance conditions, the Company derives the requisite service period from the grant date to the date 
it is probable that the vesting conditions will be met. 

The Company uses the Black‑Scholes option‑pricing model to estimate the fair value of stock options issued to 
employees  and  non-employees.  The  Monte  Carlo  simulation  model  is  used  to  estimate  the  fair  value  of  market-based 
condition awards. The model requires the input of the Company's expected stock price volatility, the expected term of the 
awards, and a risk-free interest rate. Determining these assumptions requires significant judgment. See further discussion 
on the valuation assumptions used under Note 9. 

On January 1, 2019, the Company adopted ASU 2018-07, which allows the accounting for nonemployee awards 
to be treated the same as for employee awards. The fair value of non-employee awards is now determined based on a one-
time measurement at the grant date, and it is no longer subject to periodic remeasurement. The Company continues to 
recognize stock-based compensation expense as services are rendered by the non-employees over the vesting period, which 

98 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
is accounted for on a straight-line basis. See further discussion under the Recently Adopted Accounting Pronouncements 
section within this footnote, as well as the election of certain accounting policy as a result of the adoption. 

The Company uses the Black-Scholes option-pricing model and the Monte Carlo simulation model to estimate 
the fair value of stock options issued to employees and non-employees. The model requires the input of the Company's 
expected stock price volatility, the expected term of the awards, and a risk-free interest rate. Determining these assumptions 
requires significant judgment. See further discussion on the valuation assumptions used under Note 9. 

Capitalized Software Held for Internal Use  

The  Company  capitalizes  salaries  and  related  costs  of  employees  and  consultants  who  devote  time  to  the 
development  of  internal-use  software  development  projects.  Capitalization  begins  during  the  application  development 
stage, once the preliminary project stage has been completed, which includes successful validation and approval from 
management. If a project constitutes an enhancement to previously developed software, the Company assesses whether 
the enhancement is significant and creates additional functionality to the software, thus qualifying the work incurred for 
capitalization. Once the project is available for general release, capitalization ceases and the Company estimates the useful 
life  of  the  asset  and  begins  amortization.  The  Company  periodically  assesses  whether  triggering  events  are  present  to 
review  internal-use  software  for  impairment.  Changes  in  estimates  related  to  internal-use  software  would  increase  or 
decrease operating expenses or amortization recorded during the reporting period.  

The Company amortizes its internal-use software over the estimated useful lives of three years. The net book 
value of capitalized software held for internal use was $1.7 million and $1.2 million as of December 31, 2020 and 2019, 
respectively. Amortized expense for amounts previously capitalized for the years ended December 31, 2020, 2019, and 
2018 was $1.0 million, $1.2 million, and $1.3 million, respectively.

Property and equipment, including purchased and internally developed software, are stated at cost. Depreciation 
is calculated using the straight-line method over the estimated useful lives of the assets, which are generally three to five 
years. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the assets 
or the remaining term of the lease, whichever is shorter. The Company periodically reviews the depreciable lives assigned 
to property and equipment placed in service and change the estimates of useful lives to reflect the results of such reviews.

Impairment of Long-lived Assets 

The Company evaluates its long-lived assets for indicators of possible impairment when events or changes in 
circumstances indicate the carrying amount of an asset may not be recoverable. The Company then compares the carrying 
amounts  of  the  assets  with  the  future  net  undiscounted  cash  flows  expected  to  be  generated  by  such  asset.  Should  an 
impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s 
fair value determined using discounted estimates of future cash flows.  

Inventory  

Inventory  is  valued  at  the  lower  of  the  standard  cost,  which  approximates  actual  cost,  or  market.  Cost  is 
determined using the first-in, first-out ("FIFO") method. Inventory consists entirely of supplies, which are consumed when 
providing its test reports, and therefore does not maintain any finished goods inventory. The Company enters into inventory 
purchases and commitments so that it can meet future delivery schedules based on forecasted demand for its tests. 

The Company recorded inventory obsolescence charges totaling $0.2 million, $0.3 million, and $0.3 million in 

the years ended December 31, 2020, 2019, and 2018, respectively. 

Recent Accounting Pronouncements 

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the 
“FASB”)  under  its  accounting  standard  codifications  (“ASC”)  or  other  standard  setting  bodies  and  adopted  by  the 
Company as of the specified effective date. Unless otherwise discussed below, the Company believes that the impact of 
recently issued standards that are not yet effective will not have a material impact on its financial position or results of 
operations upon adoption. 

Recently Adopted Accounting Pronouncements 

Fair Value Measurement 

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—
Changes  to  the  Disclosure  Requirements  for  Fair  Value  Measurement.  ASU  2018-13  proposes  new  disclosure 
requirements for unrealized gains or losses recognized in other comprehensive income that are attributable to fair value 
changes in assets and liabilities categorized within Level III of the fair value hierarchy, as well as quantitative information 
about significant unobservable inputs used to value such assets and liabilities. It eliminates the requirement to disclose the 
reasons for the transfers of assets and liabilities measured in fair value on a recurring basis between Level I and Level 
II. The Company has adopted this ASU as of January 1, 2020, which did not have a material impact on its consolidated 
financial statements. 

Goodwill - Internal-Use Software 

In  August  2018,  the  FASB  issued  ASU  2018-15, Intangibles-Goodwill  and  Other-Internal-Use  Software 
(Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That 
Is a Service Contract. The amendments in this update align the requirements for capitalizing implementation costs incurred 
in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to 
develop  or  obtain  internal-use  software  (and  hosting  arrangements  that  include  an  internal-use  software  license).  The 
accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in 
this update. The Company adopted ASU 2018-15 as of January 1, 2020 using the prospective approach, which did not 
have a material impact on its consolidated financial statements upon the adoption. 

Credit Losses 

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit 
Losses  on  Financial  Instruments and  also  issued  subsequent  amendments  to  the  initial  guidance:  ASU  2018-19,  ASU 

100 

 
 
 
 
 
 
 
 
2019-04, and ASU 2019-05. The standard requires measurement and recognition of expected credit losses for financial 
assets by requiring an allowance to be recorded as an offset to the amortized cost of such assets. For available-for-sale 
debt securities, expected credit losses should be estimated when the fair value of the debt securities is below their associated 
amortized  costs.  The  Company  adopted  ASU  2016-13,  as  amended,  effective  January  1,  2020  using  the  modified 
retrospective method and recorded a cumulative-effect adjustment of $0.4 million in accumulated deficit as of January 1, 
2020. 

Collaborative Arrangements 

In November 2018,  the  FASB  issued ASU  2018-18, Collaborative  Arrangements  (Topic  808):  Clarifying  the 
Interaction  between  Topic  808  and  Topic  606,  which  clarifies  that  certain  transactions  between  participants  in  a 
collaborative arrangement should be accounted for under ASC 606 when the counterparty is a customer. In addition, Topic 
808 precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from 
contracts with customers if the counterparty is not a customer for that transaction. This guidance will be effective for the 
Company beginning January 1, 2020. The Company has adopted this standard as of January 1, 2020, which did not have 
a material impact on its consolidated financial statements upon the adoption. 

Income Taxes 

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), 
which  simplifies  the  accounting  for  income  taxes,  eliminates  certain  exceptions  within  ASC  740,  Income  Taxes,  and 
clarifies certain aspects of the current guidance to promote consistency among reporting entities. ASU 2019-12 is effective 
for fiscal years beginning after December 15, 2020. An entity that elects early adoption must adopt all the amendments in 
the  same  period.  Most  amendments  within  this  ASU  are  required  to  be  applied  on  a  prospective  basis,  while  certain 
amendments must be applied on a retrospective or modified retrospective basis. The Company has adopted this standard 
as of September 30, 2020, which did not have a material impact on its consolidated financial statements upon the adoption. 

New Accounting Pronouncements Not Yet Adopted 

In March 2020, ASU 2020-04, Reference Rate Reform (Topic 848) was issued which provides temporary optional 
guidance  to  ease  the  potential  burden  in  accounting  for  reference  rate  reform.  The  new  guidance  provides  optional 
expedients and exceptions for applying generally accepted accounting principles to transactions affected by reference rate 
reform  if  certain  criteria  are  met.  These  transactions  include  contract  modifications,  hedging  relationship,  and  sale  or 
transfer of debt securities classified as HTM. Early adoption of this ASU is permitted, and the Company may elect to apply 
the amendments prospectively through December 31, 2022. The Company’s financial instruments that are in the scope of 
ASU  2020-04  include  but  are  not  limited  to  the  UBS  credit  line  agreement.  The  Company  is  currently  evaluating  the 
impact of the adoption of this standard on its consolidated financial statements. 

In August 2020, ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and 
Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) was issued which simplifies the accounting for convertible 
instruments. The guidance removes certain accounting models which separate the embedded conversion features from the 
host  contract  for  convertible  instruments.  The  Company  expects  the  elimination  of  these  models  will  reduce  reported 
interest expense and increase reported net income for the Company’s existing convertible instruments falling under the 
scope of those models before the adoption of ASU 2020-06. ASU 2020-06 requires the application of the if-converted 
method when calculating diluted earnings per share, eliminating the Company’s ability to use the treasury stock method 
when certain conditions are met. The ASU is effective for annual reporting periods beginning after December 15, 2021, 
with  early  adoption  permitted  no  earlier  than  fiscal  years  beginning  after  December  15,  2020.  Either  a  modified 
retrospective  method  of  transition  or  a  fully  retrospective  method  of  transition  is  permissible  for  the  adoption  of  this 
standard. Management is currently evaluating the impact of the adoption of this ASU on the Company’s consolidated 
financial statements. 

In  October  2020,  ASU  2020-10, Codification  Improvements,  was  issued  which  simplifies  the  existing 
codification. The guidance includes presentation disclosures for the amount of income tax expense or benefit related to 
other comprehensive income. ASU 2010-10 is effective for fiscal years beginning after December 15, 2020, including 

101 

 
interim periods within those fiscal years. Early application of the amendments is permitted for public business entities for 
any annual or interim period for which financial statements have not been issued. The Company is currently evaluating 
the impact of the adoption of this standard on its consolidated financial statements. 

3.    Revenue Recognition 

The  Company  recognizes  revenues  when,  or  as,  performance  obligations  in  the  contracts  are  satisfied,  in  the 

amount reflecting the expected consideration to be received from the goods or services transferred to the customers. 

Product Revenues 

Product  revenues  are  derived  from  contracts  with  insurance  carriers,  laboratory  partners  and  patients  in 
connection with sales of prenatal genetic and other diagnostics tests. The Company enters into contracts with insurance 
carriers  with  primarily  payment  terms  related  to  tests  provided  to  the  patients  who  have  health  insurance  coverage. 
Insurance carriers are considered as third-party payers on behalf of the patients, and the patients are considered as the 
customers  who  receive  genetic  test  services.  Tests  may  be  billed  to  insurance  carriers,  patients,  or  a  combination  of 
insurance  carriers  and  patients.  Further,  the  Company  sells  tests  to  a  number  of  domestic  and  international  laboratory 
partners and identifies the laboratory partners as customers provided that there is a test services agreement between the 
two parties. 

A performance obligation represents a promise in a contract to transfer a distinct good or service to a customer, 
which represents a unit of accounting in accordance with ASC 606. A performance obligation is considered distinct from 
other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources 
that are readily available to the customer and is separately identified in the contract. The Company considers a performance 
obligation satisfied once the Company has transferred control of a good or service to the customer, meaning the customer 
has the ability to use and obtain the benefit of the good or service. A portion of the consideration should be allocated to 
each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The 
Company evaluates its contracts with insurance carriers, laboratory partners and patients and identifies the performance 
obligations in those contracts, which are the delivery of the test results. 

The  total  consideration which  the  Company  expects  to  collect  in  exchange  for  the  Company’s  products  is  an 
estimate and may be fixed or variable. Consideration includes reimbursement from both patients and insurance carriers, 
adjusted for variable consideration related to disallowed cases, discounts, refunds and doubtful accounts, and is estimated 
using the expected value approach. For insurance carriers with similar reimbursement characteristics, the Company uses 
a portfolio of relevant historical data to estimate variable consideration and total collections for the Company’s products. 
The Company constrains the estimated variable consideration when it assesses it is probable that a significant reversal in 
the amount of cumulative revenue recognized may occur in future periods. The consideration expected from laboratory 
partners  usually  includes  a  fixed  amount,  but  it  can  be  variable  depending  on  the  volume  of  tests  performed,  and  the 
Company  determines  the  variable  consideration  using  the  expected  value  approach.  For  insurance  carriers,  laboratory 
partners  and  patients,  the  Company  allocates  the  total  consideration  to  a  single  performance  obligation,  which  is  the 
delivery of the test results to the customers. 

When assessing the total consideration for insurance carriers and patients, a certain percentage of revenues is 

further constrained for estimated refunds. 

The Company generally bills an insurance carrier, a laboratory partner or a patient upon delivery of test results. 
The Company also bills patients directly for out-of-pocket costs involving co-pays and deductibles that they are responsible 
for. Tests billed to insurance carriers and directly to patients usually take an average of nine to twelve months to collect 
takes 
laboratory  distribution  partners, 
payment,  and 
approximately two to three months. At times, the Company may or may not get reimbursed for the full amount billed. 
Further, the Company may not get reimbursed at all for tests performed if such tests are not covered under the insurance 
carrier’s reimbursement policies or the Company is not a qualified provider to the insurance carrier, or if the tests were 
not previously authorized.

Product revenue is recognized in an amount that equals to the total consideration (as described above) at a point 
in time when the test results are delivered. The Company reserves certain amounts in other accrued liabilities on the balance 
sheet in anticipation of requests for refunds of payments previously made by insurance carriers, which are accounted for 
as reductions in product revenues in the statement of operations and comprehensive loss. During the years ended December 
31,  2020,  2019,  and  2018,  $5.4  million,  $2.4  million,  and  $3.3  million,  respectively,  were  released  from  amounts 
previously held in reserves in other accrued liabilities and recognized as product revenue. 

Licensing and Other Revenues 

The Company recognizes licensing revenues from its cloud-based distribution service offering, Constellation, by 
granting  licenses  to  its  licensees  to  use  certain  of  the  Company’s  proprietary  intellectual  properties  and  cloud-based 
software and IVD kits. The Company also recognizes revenues from the Signatera research use only (“RUO”) offering, 
the Qiagen LLC, BGI Genomics Co., Ltd., and Foundation Medicine, Inc. agreements. 

Constellation 

The laboratory partners with which the Company enters into a licensing arrangement represent the licensees and 
are identified as customers. The licensees do not have the right to possess the Company’s software, but rather receive 
professional services through the cloud software. These arrangements often include: (i) the delivery of the services through 
the cloud software, (ii) the necessary support and training, and (iii) the IVD kits to be consumed as tests are processed. 
The Company does not consider the software as a service, the support and training as being distinct in the context of such 
arrangements, and therefore they are combined as a single performance obligation. The software, support and training are 
delivered simultaneously to the licensees over the term of the arrangement. 

The Company bills the majority of licensees, who process the tests in their laboratories, a fixed price for each test 
processed. Licensing revenues are recognized as the performance obligations are satisfied (i.e., upon the delivery of each 
test) and reported in licensing and other revenues in the statements of operations and comprehensive loss. 

Signatera 

The Company enters into agreements with pharmaceutical companies to utilize the Company’s Signatera tests 
typically  to  study  new  cancer  treatments  or  to  validate  the  outcomes  of  clinical  trials  for  which  the  pharmaceutical 
companies  are  identified  as  customers.  Such  arrangements  generally  involve  performing  whole  exome  sequencing 
(“WES”) services and the testing of patient samples to detect cancer mutations using its Signatera test. Each test is billable 
to  customers  and  the  personalized  cancer  profile  also  makes  each  test  distinct  within  the  context  of  the  contract  as 
customers can exercise control over the test results upon delivery. The Company allocates the contract price to each test 
using the stand-alone selling price for each service and recognizes the test processing revenue as individual test results are 
delivered to customers. 

Qiagen 

In March 2018, the Company entered into a License, Development and Distribution Agreement (“the Qiagen 
Agreement”) with Qiagen under which the Company granted Qiagen a license to develop, manufacture, distribute and 
commercialize  NGS-based  genetic  testing  assays  and  sequencing  systems  utilizing  such  assays,  which  incorporate  the 
Company’s proprietary technology. According to the terms of the agreement, the Company is initially entitled to receive 
an upfront license fee and prepaid royalties totaling $40.0 million, which was fully collected in 2018. All or a portion of 
the prepaid royalties are refundable in limited circumstances. In addition, the Company was entitled to potential milestone 
payments from Qiagen upon the successful achievement of certain volume, regulatory and commercial milestones, and 
tiered  royalties  of  $10.0  million,  of  which  the  Company  received  $5.0  million  due  December  31,  2018.  The  Qiagen 
Agreement has a term of 10 years and expires in March 2028, and it may be terminated earlier in certain circumstances. 
Upon termination of the Qiagen Agreement, the license granted to Qiagen will also terminate, except in certain limited 

103 

  
 
 
 
 
 
 
circumstances. The Company provided to Qiagen standard indemnification protections, which is part of an assurance that 
the license meets the contract’s specifications and is not an obligation to provide goods or services.   

In October 2019, Qiagen announced that it had discontinued the development of its next generation sequencing 
platform and is now partnered with another supplier to develop next generation sequencing based tests. The Company 
subsequently notified Qiagen of its material breach of the Qiagen Agreement. 

Effective in March 2020, the Company terminated the Qiagen Agreement, and all or a portion of the prepaid 
royalties are refundable in limited circumstances, including upon termination in certain circumstances. The parties are 
currently in discussions regarding their respective obligations resulting from the termination of the Qiagen Agreement. 
Because the amount of prepaid royalty subject to refund is not finalized, the refund amount, if any, is uncertain as of 
December 31, 2020. As a result, this variable consideration was not included in the transaction price in 2020 to mitigate 
the  risk  of  significant  reversal  of  the  cumulative  revenue  in  the  subsequent  periods.  Accordingly,  no  revenues  were 
recognized on the prepaid royalties which may be subject to a refund. 

BGI Genomics 

In  February  2019,  the  Company  entered  into  a  License  Agreement  with  BGI  Genomics  Co.,  Ltd.  (“BGI 
Genomics”) to develop, manufacture, and commercialize NGS-based genetic testing assays for clinical and commercial 
use. The agreement has a term of ten years and expires in February 2029. According to the agreement, the Company is 
entitled to a total of $50 million, comprised of upfront technology license fees, prepaid royalties relating to future sales of 
licensed  products  and  performance  of  assay  interpretation  services,  and  milestone  payments.  During  the  three  months 
ended June 30, 2019, the Company received $35.6 million, net of withholding taxes, of these amounts. The Company 
recorded a receivable of $2.5 million upon achieving the first milestone as of June 30, 2019, which was received in January 
2021. Also, as required by the agreement with BGI Genomics, in June 2019 the Company prepaid $6.0 million to BGI 
Genomics for future sequencing services and $4.0 million for future sequencing equipment. These advance payments for 
equipment and services to be received in future periods aggregating to $10.0 million were recorded in long-term advances 
on the Balance Sheet. 

Pursuant to the agreement, the Company licensed its intellectual property and will provide development services. 
Following completion of development services, the Company will provide assay interpretation services over the term of 
the agreement. The Company concluded that the license is not a distinct performance obligation as it does not have a stand-
alone value to BGI Genomics apart from the related development services. Therefore, license and related development 
services, for each of NIPT and Oncology products, represents a single performance obligation. 

The  Company  is  responsible  for  granting  a  license  to  specified  intellectual  property  and  performing  certain 
development  activities  to  customize  its  genetic  testing  assays  for  oncology  and  NIPT  for  use  with  BGI  Genomics’ 
sequencing instruments and proprietary technology platform. Revenue associated with these performance obligations is 
recognized over time using the input method, based on costs incurred to perform the development services, since the level 
of  costs  incurred  over  time  best  reflect  the  transfer  of  development  services.  Revenue  associated  with  the  assay 
interpretation  services  will  be  recognized  upon  delivery  of  these  services.  Funds  received  in  advance  are  recorded  as 
deferred revenue and will be recognized as the related services are delivered. 

The initial transaction price was primarily comprised of license and milestone fees. The Company constrains the 
estimated variable consideration when it assesses it is probable that a significant reversal in the amount of cumulative 
revenue recognized may occur in future periods. Certain milestone and license fees were constrained and not included in 
the transaction price due to the uncertainties of research and development. The Company re-evaluates the transaction price, 
including  the  estimated  variable  consideration  included  in  the  transaction  price  and  all  constrained  amounts,  in  each 
reporting  period  and  as  uncertain  events  are  resolved  or  other  changes  in  circumstances  occur.  The  allocation  of  the 
transaction  price  was  performed  based  on  standalone  selling  prices,  which  are  based  on  estimated  amounts  that  the 
Company would charge for a performance obligation if it were sold separately. 

In accordance with ASC 340-40, any incremental costs incurred to obtain a contract with a customer are required 
to  be  capitalized  and  amortized  over  the  period  in  which  the  goods  and  services  are  transferred  to  the  customer.  The 

104 

  
 
 
Company has elected to apply a practical expedient under ASC 340-40 to recognize the incremental costs of obtaining a 
contract as an expense when incurred provided that the amortization period of such costs, if capitalized, is one year or less. 
The incremental costs incurred in connection with the BGI Genomics arrangement is not material on an accumulated basis 
and therefore will not be capitalized on the balance sheet but will be expensed as incurred. 

Foundation Medicine, Inc. 

In August 2019, the Company entered into a License and Collaboration Agreement (“the Foundation Medicine 
Agreement”)  with  Foundation  Medicine,  Inc.  (“Foundation  Medicine”)  to  develop  and  commercialize  personalized 
circulating tumor DNA monitoring assays, for use by biopharmaceutical and clinical customers who order Foundation 
Medicine’s FoundationOne CDx. The agreement has an initial term of five years, expiring in August 2024, with automatic 
renewals thereafter for successive one-year terms, unless the agreement is earlier terminated in accordance with its terms. 
Natera and Foundation Medicine will share the revenues generated from both biopharmaceutical and clinical customers in 
accordance with the terms of the agreement. The agreement provides for approximately $13.3 million in upfront licensing 
fees and prepaid revenues payable to the Company, and up to approximately $32.0 million in minimum annual payments 
and payments tied to the Company’s achievement of certain developmental, regulatory, and commercial milestones. As of 
December 31, 2019, the Company received $16.3 million of these amounts, of which $3.0 million was for achieving certain 
milestones, and $13.3 million was for licensing fees and prepaid revenue. No additional payments have been received in 
the year ending December 31, 2020. 

Pursuant to the agreement, the Company will provide development services in conjunction with granting the use 
of the Company’s intellectual property. Following completion of those development services, the Company will provide 
assay  testing  services  over  the  term  of  the  agreement.  The  Company  has  concluded  that  the  license  is  not  a  distinct 
performance obligation as it is highly interrelated and interdependent with the related development services. Therefore, 
license and related development services represent a single performance obligation. 

The  Company  is  responsible  for  providing  the  technology  license  and  certain  development  services  that  are 
required  to  customize  its  proprietary  Signatera  test  to  work  with  Foundation  Medicine’s  FoundationOne  CDx.  The 
intellectual  property  has  been  licensed  to  Foundation  Medicine  for  the  customized  test.  In  addition,  the  Company  is 
responsible for delivering clinical study plans in order to demonstrate efficacy of the customized test. Revenues associated 
with each of the performance obligations are recognized over time using the input method, based on costs incurred to 
perform  the  development  services,  since  the  level  of  costs  incurred  over  time  best  reflect  the  transfer  of  development 
services. Revenue associated with the assay testing services will be recognized upon delivery of these services. Funds 
received in advance are recorded as deferred revenue and will be recognized as the related services are delivered. 

The initial transaction price was primarily comprised of license and milestone fees. The Company constrains the 
estimated variable consideration when it assesses it is probable that a significant reversal in the amount of cumulative 
revenue  recognized  may  occur  in  future  periods.  Certain  milestone  fees  were  constrained  and  not  included  in  the 
transaction price due to the uncertainties of research and development. The Company re-evaluates the transaction price, 
including  the  estimated  variable  consideration  included  in  the  transaction  price  and  all  constrained  amounts,  in  each 
reporting  period  and  as  uncertain  events  are  resolved  or  other  changes  in  circumstances  occur.  The  allocation  of  the 
transaction  price  was  performed  based  on  standalone  selling  prices,  which  are  based  on  estimated  amounts  that  the 
Company would charge for a performance obligation if it were sold separately. 

In accordance with ASC 340-40, any incremental costs incurred to obtain a contract with a customer are required 
to  be  capitalized  and  amortized  over  the  period  in  which  the  goods  and  services  are  transferred  to  the  customer.  The 
Company has elected to apply a practical expedient under ASC 340-40 to recognize the incremental costs of obtaining a 
contract as an expense when incurred provided that the amortization period of such costs, if capitalized, is one year or less.

Foundation Medicine, and the remaining $0.4 million related to genetic testing services. During the year ended December 
31, 2020, $1.2 million was recognized as deferred revenue and later earned as revenue in the same period. The current 
portion of deferred revenue includes $3.9 million from the BGI Genomics agreement and $6.2 million from the Foundation 
Medicine agreement.  

4.    Fair Value Measurements 

The Company's financial assets and liabilities carried at fair value are comprised of investment assets that include 

money market and investments, and a liability for common stock warrants.   

The fair value accounting guidance requires that assets and liabilities be carried at fair value and classified in one 

of the following three categories: 

Level I: Quoted prices in active markets for identical assets and liabilities that the Company has the ability to 
access. 

Level II: Observable market-based inputs or unobservable inputs that are corroborated by market data, such as 
quoted prices, interest rates, and yield curves. 

Level III: Inputs that are unobservable data points that are not corroborated by market data. 

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

unobservable inputs when determining fair value. 

Assets and Liabilities That Are Measured at Fair Value on a Recurring Basis 

The following table represents the fair value hierarchy for the Company’s financial assets and financial liabilities

(1)  Per  the  Company’s  investment  policy,  all  U.S.  Treasury  securities,  corporate  bonds  and  notes  are  classified  as  short-term  investments

irrespective of holding period.   

(2)  Cash equivalents includes cash sweep accounts and U.S. Treasury money market mutual funds. 

The Company invests in U.S. Treasuries, U.S. agency  and high quality municipal bonds which mature at par 
value and are all paying their coupons on schedule. The Company has therefore concluded there is currently no other than 
temporary impairment of its investments and will continue to recognize unrealized gains and losses in other comprehensive 
income (loss). During the year ended December 31, 2020, the Company sold $30.1 million of investments. There were no 
sales of investments during the year ended December 31, 2019. During the year ended December 31, 2020, the amount of 
gross  realized  gains  and  realized  losses  upon  sales  of  investments  were  insignificant.  The  Company  uses  the  specific 
investment  identification  method  to  calculate  realized  gains  and  losses  and  amounts  reclassified  out  of  other 
comprehensive income to net income. As of December 31, 2020, the Company had 13 investments in an unrealized loss 
position in its portfolio. An allowance for credit losses was not necessary since the fair market value for a majority of the 
available-for-sale securities increased as a result of a significant average yield rate decrease for similar securities as of 
December 31, 2020. 

In accordance with the adoption of ASU 2016-13 (Topic 326), the Company has assessed the unrealized loss 
position for available-for-sale debt securities for which an allowance for credit losses has not been recorded. The fair value 
for investment securities at an unrealized loss position as of December 31, 2020 was $144.0 million. The aggregate amount 
of unrealized losses of these securities were not significant, and the impact of the securities in a continuous loss position 
to the consolidated statements of operations and comprehensive loss were not material as of December 31, 2020.

Other Assets 

In August 2017, the Company entered into the 2017 Term Loan with OrbiMed (as described in Note 10, Debt) 
and issued 300,000 shares of its common stock in exchange for OrbiMed’s initial and remaining funding commitments. 
In  April  2019,  the  Company  issued  an  additional  25,000  shares  of  its  common  stock  to  OrbiMed  for  extending  the 
expiration date to draw the unused borrowing capacity until December 31, 2019. The Company previously classified $1.2 
million out of the total debt issuance costs in noncurrent assets for the unused borrowing capacity of $50.0 million. The 
debt discount was amortized on a straight-line basis over the remaining term of the loan. Since the option to draw the 
unused borrowing capacity has expired as of December 31, 2019, the Company reclassed $0.9 million, the unamortized 
portion of debt issuance cost previously classified in noncurrent assets, to long-term debt financing. Subsequently, the debt 
was  extinguished  (See  Note  10,  Debt)  and  accordingly,  as  of  December  31,  2020,  total  unamortized  remaining  in 
noncurrent assets was zero. Additionally, as of December 31, 2020, other assets also included long-term advances to BGI 
Genomics of $10.0 million for future sequencing equipment and services.

7.    Leases 

Operating Leases  

In September 2015, the Company’s subsidiary entered into a long-term lease agreement for laboratory and office 
space totaling approximately 94,000 square feet in Austin, Texas. The lease term is 132 months beginning in December 
2015 and expiring in November 2026 with monthly payments beginning in December 2016. 

In October 2016, the Company entered into a lease directly with its landlord for laboratory and office spaces at 
its  facilities  located  in  San  Carlos,  California.  The  Company  currently  occupies  approximately 113,000 square  feet 
comprised  of two office  spaces 
the  “Second  Space”).  The  First  Space  covers 
approximately 88,000 square feet, and the Second Space totals approximately 25,000 square feet. The term of this lease is 
approximately 84 months and expires in October 2023. This lease contains an option to renew the lease term for five years, 
but the fair market rent amount upon renewal is not available from the landlord. In January 2021, the Company entered 

(the  “First  Space”  and

into an amendment of the lease to extend the term for 48 months to October 2027. The combined annual rent for the First 
Space and Second Space will be $9.3 million commencing in October 2023. 

The Company entered into a lease agreement commencing June 2018 for its cord blood tissue storage facility in 
Tukwila, Washington that covers approximately 10,000 square feet. The lease term is 62 months expiring in July 2023. 
The Company has the option to extend this lease for five years, and the fair market rent upon renewal is not determinable. 
However, since the Company sold its business related to cord blood and tissue storage in September 2019, the Company 
has subleased the facility and does not intend to exercise its option to renew the facility upon expiration. 

In  addition,  the  Company  entered  into  a  sublease  agreement  in  June  2019  with  a  third  party  to 
sublease 25,879 square feet of space located on the third floor of the San Carlos, California building while maintaining its 
primary obligation as the intermediate lessor. The term of this lease is approximately 48 months commencing in October 
2019  and  expiring  in  September  2023.  The  annual  lease  payment  starts  at  $1.9 million  and  will  escalate  annually 
commencing in October 2020. In February 2021, the Company entered into an amendment of the San Carlos sublease 
agreement whereas the third party will initially return approximately 3,474 rentable square feet with the remainder of the 
subleased premises, consisting of approximately 22,405 rentable square feet, between October 2021 and December 2021. 

The Company entered into a lease agreement in November 2020 to lease 11,395 square feet of space located in 
South  San  Francisco,  California  over  a  36-month  term.  The  premises  will  be  used  for  general  office,  laboratory  and 
research use. The annual lease payment starts at $0.9 million and will escalate annually commencing in December 2021. 

The Company has also entered into leases of individual workspaces at premises located in different locations on 
a month-to-month basis and is not committed to an established lease term. The Company has elected to not recognize them 
as the right-of-use assets on the balance sheet as they are all considered as short-term leases. Expenses associated with 
short-term lease were not significant for the year ended December 31, 2020.The operating lease right-of-use assets are 
classified as noncurrent assets in the balance sheet. The corresponding lease liabilities are separated into current and long-
term portions as follows:

The initial recognition of the operating lease liabilities was measured as the present value of the future minimum 
lease payments using a discount rate determined as of January 1, 2019. The operating right-of-use assets was calculated 
as  the  operating  lease  liabilities  discounted  at  the  present  value,  less  the  amount  of  unamortized  tenant  improvement 
allowance and deferred rent. The discount rate used was the Company’s incremental borrowing rate given that the implicit 
rate to each lease was not readily determinable. In accordance with ASC 842, the incremental borrowing rate was estimated 
as the annual percentage yield resulting from a corporate debt financing over a loan term approximating the remaining 
term of each lease, with the effect of certain credit risk rating. For the year ended December 31, 2020, we had noncash 
investing activities of $2.4 million related to right-of-use assets. As of December 31, 2020, the weighted-average remaining 
lease term was 2.28 years and the weighted-average discount rate was 10.68%. 

The  Company  continues  to  recognize  lease  expense  on  a  straight-line  basis.  The  lease  expense  includes  the 
amortization  of  the  right-of-assets  with  the  associated  interest  component  estimated  by  applying  the  effective  interest 
method. Total lease expense recognized in the statements of operations and comprehensive loss were $7.8 million, $7.8 
million,  and  $7.4  million  for  the  years  ended  December  31,  2020,  2019  and  2018.  Cash  paid  for  amounts  in  the 
measurement of operating lease liabilities totaled $9.0 million, $8.6 million and $7.9 million for the years ended December 
31, 2020, 2019 and 2018, respectively.

8.    Commitments and Contingencies 

Legal Proceedings 

From time to time, the Company is involved in disputes, litigation, and other legal actions, including those with 
respect to intellectual property, employment, testing and other matters. Such actions may include allegations of negligence, 
products/professional liability or other similar legal claims, and could involve claims for substantial compensatory and/or 
punitive  damages  or  claims  for  indeterminate  amounts  of  damages.  The  Company  is  aggressively  defending  and/or 
prosecuting its current litigation matters, but cannot provide any assurance as to the ultimate outcome or that an adverse 
resolution would not have a material adverse effect on its financial condition and results of operations. There are many 
uncertainties associated with any litigation and these actions or other third party claims against the Company, or by the 
Company against third parties, may cause the Company to incur costly litigation and/or substantial settlement charges. In 
addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which 
could adversely affect gross margins in future periods. If this were to occur, the Company's business, financial condition, 
results of operations, and cash flows could be adversely affected. 

The Company assesses legal contingencies to determine the degree of probability and range of possible loss for 
potential accrual in its financial statements. When evaluating legal contingencies, the Company may be unable to provide 
a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence 
of complex or novel legal theories, and/or the ongoing discovery and development of information important to the matters. 
In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible 
outcomes, and as such are not meaningful indicators of its potential liability. During the periods presented, the Company 
has not recorded any accrual for loss contingencies associated with such legal proceedings, determined that an unfavorable 
outcome is probable or reasonably possible, or determined that the amount or range of any possible loss is reasonably 
estimable.

Intellectual Property Litigation Matters. 

In March 2018, Illumina, Inc., or Illumina, filed a lawsuit (the ’831 lawsuit) against the Company in the United 
States District Court for the Northern District of California, alleging that the Company’s Panorama test infringes certain 
claims of U.S. Patent No. 9,493,831 (the ’831 patent) and seeking, among other relief, damages or other monetary relief 
including costs and pre- and post-judgment interest, treble damages, injunctive relief, attorneys’ fees and costs. In August 
2018, the Company filed a counterclaim against Illumina, alleging that certain of Illumina’s NIPT tests infringe on the 
Company’s U.S. Patent No. 8,682,592 (the ’592 patent) and seeking, among other relief, damages or other monetary relief 
including costs and pre- and post-judgment interest, treble damages, injunctive relief, attorneys’ fees and costs (together 
with the ‘831 lawsuit, the “Illumina Litigation”). In May 2020, the parties settled the Illumina Litigation pursuant to which 
all  claims  in  the  Illumina  Litigation,  including  compulsory  counterclaims,  relating  to  NIPT  and  PGS/PGD  activities 
occurring before the date of such settlement were resolved and dismissed. Separately, on December 11, 2020, the United 
States  Patent  and  Trademark  Office  issued  a  final  written  decision  affirming  the  validity  of  all  claims  challenged  by 
Illumina in its inter partes review petition filed in June 2019. Illumina has affirmatively waived its right to appeal this 
decision, leaving the previously challenged claims of the ‘592 patent valid and fully enforceable. 

The Company is involved in patent litigation against CareDx, Inc., or CareDx, in the United States District Court 
for  the  District  of  Delaware  (“CareDx’s  Patent  Case”).  CareDx  alleges,  in  a  complaint  filed  on  March  26,  2019  and 
amended on March 23, 2020, that the Company infringed three patents. The complaint seeks unspecified damages and 
injunctive  relief.  The  Company  has  also  alleged  that  CareDx  infringes  two  of  Natera’s  patents,  seeking  unspecified 
damages and injunctive relief. The Court has set a trial date of April 25, 2022. Natera is also opposing a European patent 
held by CareDx, with oral proceedings scheduled for May 11, 2021.  

The Company is also the subject of a lawsuit filed by CareDx against the Company on April 10, 2019 in the 
United  States  District  Court  for  the  District  of  Delaware,  alleging  false  advertising,  trademark  disparagement,  unfair 
competition, and unfair or deceptive trade practices based on statements describing studies that concern the Company’s 
technology  and  CareDx’s  technology  (“CareDx’s  Advertising  Case”).  The  complaint  seeks  unspecified  damages  and 
injunctive relief. On May 30, 2019, the Company filed a motion to dismiss the entirety of CareDx’s Advertising Case for 
failure  to  state  a  claim.  On  February  7,  2020,  CareDx  filed  an  amended  complaint  withdrawing  its  trademark 
disparagement claim. On February 18, 2020, the Company filed a counterclaim against CareDx in the United States District 
Court for the District of Delaware, alleging false advertising, unfair competition and deceptive trade practices and seeking 
unspecified damages and injunctive relief.  On December 2, 2020 the parties cross-moved for partial summary judgment.   

The Company has filed suit against ArcherDX, Inc., or ArcherDX, in the United States District Court for the 
District of Delaware, alleging, in complaints filed on January 27, 2020, April 15, 2020 and August 6, 2020, that certain 
ArcherDX DNA oncology products infringe four of Natera’s patents.  Natera is seeking monetary damages and injunctive 
relief. On June 4, 2020, ArcherDX filed a motion to dismiss aspects of the Company’s case, including to invalidate several 
of Natera’s asserted patents. That motion was denied in its entirety on October 2, 2020. The cases were consolidated on 
September 25, 2020. On January 12, 2021, Company filed a second amended complaint naming an additional Archer DX 
entity,  ArcherDx  LLC,  and  Invitae  Corp.  as  defendants.  The  second  amended  complaint  seeks  unspecified  monetary 
damages and injunctive relief. 

The Company is the subject of a lawsuit filed against it by Ravgen, Inc. on June 1, 2020 in the United States 
District  Court  for  the  Western  District  of  Texas,  alleging  infringement  of  two  Ravgen  patents.  The  complaint  seeks 
monetary damages and injunctive relief. Trial is tentatively set for December 13, 2021.  

The Company filed suit against Progenity, Inc., or Progenity, in the United States District Court for the Western 
District of Texas on June 17, 2020 and in the United States District Court for the Northern District of Texas on June 19, 
2020, in each case alleging that Progenity’s NIPT test infringes six of Natera’s patents. The complaints seek treble damages 
and injunctive relief. On or about July 2, 2020, Progenity filed suit against the Company in the United States District Court 
for the Southern District of California, seeking declaratory judgment of non-infringement of Natera’s asserted patents. 
Progenity has petitioned the Patent Trial and Appeal Board of the United States Patent and Trademark Office for inter 
partes review of Natera’s asserted patents.  

114 

 
 
On October 6, 2020, the Company filed suit against Genosity Inc., or Genosity, in the United States District Court 
for the District of Delaware, alleging that various Genosity oncology products infringe a Natera patent. The complaint 
seeks unspecified monetary damages and injunctive relief. 

On January 20, 2021, the Company filed suit against Inivata, Inc. and Inivata Ltd. (collectively “Inivata”) in the 
United States District Court for the District of Delaware, alleging that various Inivata oncology products infringe two 
Natera patents. The complaint seeks unspecified monetary damages and injunctive relief. 

Other Litigation Matters. 

On or about August 13, 2019, a suit was filed against the Company in the Circuit Court of Cook County, Illinois 

by a patient alleging claims relating to a discordant test result and seeking monetary damages.  

On March 15, 2019, a purported class action lawsuit was filed against the Company in the United States District 
Court for the Northern District of California, alleging that the plaintiff received an unauthorized text message to her cellular 
telephone in violation of the Telephone Consumer Protection Act. Among other relief, the complaint sought statutory and 
other damages, injunctive relief, attorneys’ fees, and costs. The case was dismissed by stipulation of the parties effective 
November 2, 2020. 

Director and Officer Indemnifications 

As permitted under Delaware law, and as set forth in the Company’s Certificate of Incorporation and its Bylaws, 
the Company indemnifies its directors, executive officers, other officers, employees and other agents for certain events or 
occurrences that may arise while in such capacity. The maximum potential amount of future payments the Company could 
be required to make under this indemnification is unlimited; however, the Company has insurance policies that may limit 
its exposure and may enable it to recover a portion of any future amounts paid. Assuming the applicability of coverage, 
the willingness of the insurer to assume coverage, and subject to certain retention, loss limits and other policy provisions, 
the Company believes any obligations under this indemnification would not be material, other than an initial $2.5 million 
for securities related claims. However, no assurances can be given that the covering insurers will not attempt to dispute 
the validity, applicability, or amount of coverage without expensive litigation against these insurers, in which case the 
Company may incur substantial liabilities as a result of these indemnification obligations. 

Third-Party Payer Reimbursement Audits 

From time to time, the Company receives recoupment requests from third-party payers for alleged overpayments. 
The Company disagrees with the contentions of pending requests and/or has recorded an accrual when a refund is deemed 
to be probable and estimable for the alleged overpayments.

Various 

General.   The Company’s board of directors adopted its 2015 Equity Incentive Plan, or the 2015 Plan, in June 

2015. The Company’s 2015 Plan replaced all of its prior stock plans.  

Share Reserve.   The initial number of shares of the Company’s common stock available for issuance under the 
2015 Plan was 3,451,495 shares. As of December 31, 2020, 13,988,187 shares were reserved for future issuance under the 
2015 plan, which includes unissued and forfeited shares from the 2007 plan. The number of shares reserved for issuance 
under the 2015 Plan will be increased automatically on the first business day of each fiscal year, commencing in 2016, by 
a number equal to the smallest of: 

• 

• 

• 

3,500,000 shares;  

4% of the shares of common stock outstanding on the last business day of the prior fiscal year; or  

the number of shares determined by the Company’s board of directors. 

Stock options vest  as  determined by  the  compensation  committee.  In general,  they will  vest  over  a four-year 
period following the date of grant. Stock options expire at the time determined by the compensation committee but in no 
event more than ten years after they are granted. These awards generally expire earlier if the participant's service terminates 
earlier.  

Restricted Shares and Stock Units.    Restricted shares and stock units may be awarded under the 2015 Plan in 
return for any lawful consideration, and participant who receive restricted shares or stock units generally are not required 
to pay cash for their awards. In general, these awards will be subject to vesting. Vesting may be based on length of service, 
the attainment of performance-based milestones or a combination of both, as determined by the compensation committee.  

2015 Employee Stock Purchase Plan 

General.    The Company’s 2015 Employee Stock Purchase Plan, or 2015 ESPP, was adopted by its board of 
directors in June 2015 and its stockholders approved it in June 2015. The 2015 ESPP is intended to qualify under Section 
423 of the Internal Revenue Code.

the number of shares determined by the Company’s board of directors. 

The number of shares reserved under the 2015 ESPP will automatically be adjusted in the event of a stock split, 

stock dividend or a reverse stock split (including an adjustment to the per-purchase period share limit). 

Purchase Price.    Employees may purchase each share of common stock under the 2015 ESPP at a price equal 
to 85% of the lower of the fair market values of the stock as of the beginning or the end of the six-month offering periods. 
An employee’s payroll deductions under the ESPP are limited to 15% of the compensation, and up to a maximum of 5,000 
shares may be purchased during any offering period. A participant shall not be granted an option under the ESPP if such 
option would permit the participant’s rights to purchase stock to accrue at a rate exceeding $25,000 fair market value of 
stock for each calendar year in which such option is outstanding at any time. 

Offering Periods.    Each offering period will last a number of months determined by the compensation committee, 
not to exceed 27 months. A new offering period will begin periodically, as determined by the compensation committee. 
Offering periods may overlap or may be consecutive. Unless otherwise determined by the compensation committee, two 
offering periods of six months' duration will begin in each year on May 1 and November 1.

The total fair value of stock options vested during the years ended December 31, 2020, 2019, and 2018 were 

$52.5 million, $11.0 million, and $11.3 million, respectively. 

Stock-Based Compensation Expense 

Stock  based  compensation  is  related  to  stock  options  and  RSUs  granted  to  the  Company’s  employees  and  is 
measured at the grant date based on the fair value of the award. The fair value is recognized as expense over the requisite 
service period, which is generally the vesting period of the respective awards on a straight-line basis. No compensation 
cost is recognized when the requisite service has not been met and the awards are therefore forfeited. 

Employee stock-based compensation expense was calculated based on awards ultimately expected to vest and 
has  been  reduced  for  estimated  forfeitures.  Forfeitures  are  estimated  at  the  time  of  grant  and  revised,  if  necessary,  in 
subsequent periods, if actual forfeitures differ from those estimates. Non-employee stock-based compensation expense 
was not adjusted for estimated forfeitures up until the occurrence of the actual forfeiture of the associated awards.

Valuation of Stock Option Grants to Employees and Non-Employees 

The Company utilizes Black-Scholes option pricing model when estimating the fair value of stock options. For 
the  year  ended  December 31,  2020  the following valuation  assumptions  were  applied on both  the  employee  and  non-
employee options. In the same period of the prior year, the valuation assumptions as follows were only used for stock 
options granted to employees.

 0  % 

As of December 31, 2020, total options outstanding include 45,577 shares of option awards that were granted to 
non-employees, of which 5,366 shares are unvested. Stock-based compensation expense related to stock options granted 
to non-employees is recognized as the stock option is earned and the services are rendered. The Company believes that the 
estimated fair value of the stock options is more readily measurable than the fair value of the services rendered.

Credit Line Agreement 

In September 2015, the Company entered into a credit line with UBS (the “Credit Line”) providing for a $50.0 
million revolving line of credit which can be drawn down in increments at any time. The Credit Line was amended in July 
2017 and bears interest at 30-day LIBOR plus 1.10%, and it is secured by a first priority lien and security interest in the 
Company’s money market and marketable securities held in its managed investment account with UBS. UBS has the right 
to demand full or partial payment of the Credit Line Obligations and terminate the Credit Line, in its discretion and without 
cause, at any time. For the years ended December 31, 2020, 2019, and 2018, the Company recorded interest expense of 
$0.8 million, $1.7 million, and $1.6 million, respectively. Interest payments totaling $0.8 million, $1.7 million, and $1.5 
million, had been made on the Credit Line during the years ended December 31, 2020, 2019, and 2018, respectively. As 
of December 31, 2020, remaining accrued interest was $1.1 million, and the total principal amount outstanding including 
accrued interest was $49.0 million.

2017 Term Loan 

In August 2017, the Company entered into the 2017 Term Loan with OrbiMed, which has a maximum borrowing 
capacity  of  $100.0 million.  On  the  closing  date  of  August  8,  2017,  the  Company  borrowed  $75.0 million,  with  the 
remaining  $25.0 million  available  to  borrow  at  the  Company’s  option  at  any  time  through  December  31,  2018. 
Subsequently, the Company entered into several amendments and extended the expiration date until December 31, 2019 
to draw the unused borrowing capacity of $50.0 million. After the amendments, the interest rate was equal to the sum of 
(i) 8.25% plus (ii) the higher of 1.00% or LIBOR, provided the Company draw the minimum capacity of $25.0 million. If 
the amount drawn is less than $25.0 million, the interest rate would remain at the sum of (i) 8.75% plus (ii) the higher 
of 1.00% or LIBOR. As a fee in consideration of extending the commitment to provide this option to draw until December 
31, 2019, the Company issued an additional 25,000 shares of our common stock to OrbiMed. As of December 31, 2019, 
the Company did not exercise such option, and the right to draw the unused borrowing capacity has expired. For the year 
ended December 31, 2020 and 2019, the Company recorded interest expense for the 2017 Term Loan totaling $2.5 million 
and $9.0 million, respectively, which also included the amortization of debt discount. 

In April 2020, the Company used a portion of the net proceeds from the offering of the Convertible Notes to 
repay its obligations under its 2017 Term Loan with OrbiMed. The payment amount was $79.2 million, which included 
the principal amount of $75.0 million, $3.8 million of early payment penalties, and $0.4 million in accrued interest. In 
accordance  with  ASC  Topic  470,  the  Company  accounted  for  this  transaction  as  debt  extinguishment.  The  difference 
between the reacquisition price of the debt and the net carrying amount of the debt on the extinguishment date is recorded 
in loss on debt extinguishment in our consolidated statements of operations and comprehensive loss. The loss on debt 
extinguishment was computed as follows:

In April 2020, the Company issued $287.5 million aggregate principal amount of Convertible Notes due 2027 in 
a private placement offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as 
amended. 

The Convertible Notes are senior, unsecured obligations of the Company and bear interest at a rate of 2.25% per 
year, payable in cash semi-annually in arrears in May and November of each year, beginning in November 2020. The 
Convertible Notes mature in May 2027, unless earlier converted, repurchased or redeemed in accordance with their terms. 
Upon  conversion,  the  Convertible  Notes  are  convertible  into  cash,  shares  of  the  Company’s  common  stock  or  a 
combination of cash and shares of the Company’s common stock, at the Company’s election. 

The Company received net proceeds from the Convertible Notes of $278.3 million, after deducting the initial 
purchasers’ discounts and debt issuance costs. The Company used approximately $79.2 million of the net proceeds from 
the Convertible Notes offering to repay its obligations under the 2017 Term Loan with OrbiMed.

of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter 
is greater than or equal to 130% of the conversion price on each applicable trading day. 

● During the five business day period after any five consecutive trading day period in which the trading price per 
$1,000 principal amount of Convertible Notes for each trading day of that five-day consecutive trading period was less 
than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each 
such trading day. 

● If the Company calls any or all of the Convertible Notes for redemption at any time prior to the close of business 

on the second business day prior to the redemption date. 

● Upon the occurrence of certain distributions. 

● Upon the occurrence of specified corporate transactions. 

The Convertible Notes are convertible into shares of the Company’s common stock, par value $0.0001 per share, 
at an initial conversion rate of 25.7785 shares of common stock per $1,000 principal amount of the Convertible Notes, 
which  is  equivalent  to  an  initial  conversion  price  of  approximately  $38.79 per  share  of  common  stock,  convertible 
to 7,411,704 shares of common stock. The conversion rate and corresponding conversion price are subject to adjustment 
upon  the  occurrence  of  certain  events  but  will  not  be  adjusted  for  any  accrued  or  unpaid  interest.  The  holders  of  the 
Convertible Notes who redeem their Convertible Notes in connection with a make-whole fundamental change are, under 
certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a fundamental change, 
the holders of the Convertible Notes may require the Company to repurchase for cash all or a portion of their Convertible 
Notes at a price equal to 100% of the principal amount, plus any accrued and unpaid interest. 

The Company may not redeem the Convertible Notes prior to May 2024, and no sinking fund is provided for the 
Convertible Notes. The Company may redeem for cash all or any portion of the Convertible Notes, at the Company’s 
option, on or after May 2024, if the last reported sale price of the Company’s common stock has been at least 130% of the 
conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending on the 
trading day immediately preceding the date on which the Company provides notice of redemption. The redemption price 
will be equal to 100% of the principal amount of the Convertible Notes to be redeemed plus accrued and unpaid interest. 
The Convertible Notes are accounted for in accordance with ASC 470-20, Debt with Conversion and Other Options, as 
the Convertible Notes may be settled entirely or partially in cash upon conversion. The Company separately accounted for 
the  liability  component  and  equity  component  of  the  Convertible  Notes  by  allocating  the  debt  proceeds  between  the 
liability and equity components. The carrying amount of the liability component is calculated by measuring the fair value 
of a similar liability that does not have an associated convertible feature. The Company used a discounted cash flow method 
and applied the average annual market yield of 7.832% as an input to measure its fair value. The allocation was performed 
in a manner that reflected the Company’s non-convertible debt borrowing rate for similar debt. The carrying amount of 
the equity component is determined by deducting the fair value of the liability component from the initial debt proceeds. 
The fair value of liability component of the Convertible Notes on the date of issuance was $201.9 million, and accordingly, 
the remaining proceeds of $85.6 million are allocated to the equity component on the date of issuance.  The carrying value 
of the liability component of the Convertible Notes is classified as long-term debt, and the equity component is classified 
as permanent equity in the Company’s consolidated balance sheet as of December 31, 2020. 

After  allocating  the  proceeds  of  the  debt  and  equity  components,  the  Company  further  allocated  $9.2 million 
initial purchasers’ debt discount and debt issuance cost of $8.6 million and $0.6 million, respectively. The debt issuance 
costs primarily consisted of legal, accounting, and other professional fees. These costs were allocated to the liability and 
equity components based on the allocation of the proceeds as follows:

The portion allocated to the liability component is amortized to interest expense using the effective interest 

method over the expected life of the Convertible Notes or approximately its seven-year term. The effective interest rate 
on the liability component of the Convertible Notes for the period from the date of issuance through May 2027 is 8.27%, 
which remains unchanged from the date of issuance.

At the original issuance date, the estimated fair value of the liability component of our Convertible Notes was 
$201.9 million and the estimated fair value of the equity component was $85.6 million as measured on the date of issuance, 
resulting in a total fair value of $287.5 million for the Convertible Note. The Convertible Notes were priced at par at the 
valuation date resulting in the fair value of the Convertible Notes equal to the principal amount of $287.5 million. The fair 
value of the Convertible Note has been calculated as the residual amount between the fair value of the Convertible Note 
and the fair value of the debt component.   

The unamortized debt discount and issuance cost is comprised of $79.1 million of debt discount resulting from 
allocating proceeds to the equity component, $5.6 million of debt discount from the liability component representing the 
difference  between  the  net  proceeds  received  upon  issuance  of  debt  and  the  amount  repayable  at  its  maturity,  and 
$0.4 million of debt issuance costs.

11.     Stockholders’ Equity 

In August 2017, the Company paid OrbiMed a fee in consideration of providing the 2017 Term Loan (as defined 
in Note 9) by issuing 300,000 shares of its common stock. The fair value of the fee was $2.4 million, which was determined 
based on the Company’s stock price of $8.16 on August 8, 2017. In June 2018, OrbiMed exercised all of its warrants,

12.    Disposal of Business 

Sale of Evercord 

In September 2019, the Company sold the Evercord business that provides cord blood and cord tissue processing 
and storage services for total estimated consideration of $15.4 million, including $9.7 million in cash, $1.0 million of cash 
deposited  in  a  third-party  escrow  account  recorded  in  short-term  other  receivables,  and  $4.7  million  of  additional 
consideration. The additional consideration is primarily related to the accounts receivable transferred to the buyer. The 
cash held in escrow serve as security for the indemnification obligations of the Company and eligible for release 12 months 
after the closing date. The assets relating to the Evercord services transferred to the buyer had a net book value of $6.2 
million as of the sale date, and consisted of accounts receivables and equipment.  The obligations and liabilities relating 
to the Evercord services transferred to the buyer consisted of deferred revenues of $5.2 million. The sale of the Evercord 
business did not meet criteria to be reported as a discontinued operation, because it did not represent a strategic shift with 
a major effect on the Company’s operations and financial results. The Company recognized a gain of $14.4 million on the 
sale, which was included in Loss from operations in the Consolidated Statements of Operations and Comprehensive Loss.

The Company established a full valuation allowance against its net deferred tax assets in 2020 and 2019 due to 
the  uncertainty  surrounding  realization  of  these  assets.  The  valuation  allowance  increased  to  $222.5  million  as  of 
December 31, 2020 from $163.0 million as of December 31, 2019 due to current year losses and credits claimed. 

As  of  December  31,  2020,  the  Company  had  federal  and  state  net  operating  loss  (“NOLs”)  carryforwards  of 
approximately $727.2 million and $412.9 million, respectively, which begin to expire in 2027 and 2028, respectively, if 
not utilized. Approximately $407.3 million of federal net operating loss included above can be carried forward indefinitely. 

The Company also had federal research and development credit carryforwards of approximately $21.4 million, 
which begin to expire in 2027, and state research and development credit carryforwards of approximately $16.9 million, 
which can be carried forward indefinitely. Realization of these deferred tax assets would require $882.4 million in taxable 
income to fully utilize. Realization is dependent on generating sufficient taxable income prior to expiration of the loss and 
credit carryforwards.  

Federal and California tax laws impose substantial restrictions on the utilization of NOLs and credit carryforwards 
in the event of an "ownership change" for tax purpose, as defined in Section 382 of the Internal Revenue Code. Accordingly, 
the  Company's  ability  to  utilize  these  carryforwards  may  be  limited  as  the  result  of  such  ownership  change.  Such  a 
limitation could result in limitation in the use of the NOLs in future years and possibly a reduction of the NOLs available.

During the years ended December 31, 2020, 2019, and 2018, the amount of unrecognized tax benefits increased 
$2.9 million, $1.3 million, and $1.4 million, respectively, due to additional research and development credits generated 
during  the  year.  As  of  December  31,  2020,  2019,  and  2018,  the  total  amount  of  unrecognized  tax  benefits  was  $11.5 
million,  $8.6  million,  and  $7.4  million,  respectively.  The  reversal  of  the  uncertain  tax  benefits  would  not  affect  the 
Company's effective tax rate to the extent that it continues to maintain a full valuation allowance against its deferred tax 
assets. 

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (CARES Act) 
was  signed  into  law  in  March  2020.  The  CARES  Act  includes  modifications  for  net  operating  loss  carryovers  and 
carrybacks, limitations of business interest expense for tax, immediate refund of alternative minimum tax (AMT) credit 
carryovers as well as a technical correction to the Tax Cuts and Jobs Act of 2017, for qualified improvement property. As 
of December 31, 2020, the Company expects that these provisions will not have a material impact as the Company has no 
net operating losses or AMT credits that would fall under these provisions and does not expect interest expense to be 
deductible due to current year losses. 

The Company is subject to U.S. federal income taxes and to income taxes in various states in the United States. 
Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations, and require 
significant judgment to apply. The Company is subject to U.S. federal, state and local tax examinations by tax authorities 
for all prior tax years since incorporation. The Company does not anticipate significant changes to its current uncertain tax 
positions through December 31, 2021. 

The Company recognizes any interest and/or penalties related to income tax matters as a component of income 

tax expense.  As of December 31, 2020, there were no accrued interest and penalties related to uncertain tax positions. 

14.     Net Loss per Share 

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to 

common stockholders by the weighted-average number of shares of common stock outstanding for the period.  

In periods when the Company has incurred a net loss, common stock equivalents such as outstanding common 
stock options, restricted stock units, unvested common shares subject to repurchase and warrants are excluded from the 
calculation of diluted net loss per share as they give an anti-dilutive effect. 

The Convertible Note is convertible as of December 31, 2020. Upon conversion, the Company has the option to 
pay cash, issue shares of common stock, or any combination thereof for the aggregate amount due upon conversion. The 
value of the Convertible Notes, if-converted, exceeds its principal amount by $388.4 million as of December 31, 2020. 
Since the Company is in a net loss position in the periods presented, the shares which would be issued upon conversion of 
the Converted Notes are excluded from the net loss per share calculation as it would have an antidilutive effect.  As such, 
the 7.4 million shares underlying the conversion option of the Convertible Notes will not have an impact on our diluted 
earnings per share. If converted, the Company does not intend to settle the obligation in cash.

CHANGES  IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND 
FINANCIAL DISCLOSURE 

ITEM 9A:  CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures 

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated 
the effectiveness of our disclosure controls and procedures as of December 31, 2020. The term “disclosure controls and 
procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures 
of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files 
or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in 
the  Securities  and  Exchange  Commission’s  rules  and  forms.  Disclosure  controls  and  procedures  include,  without 
limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports 
that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including 
its  principal  executive  and  principal  financial  officers,  as  appropriate  to  allow  timely  decisions  regarding  required 
disclosure.  

Based on the evaluation of our disclosure controls and procedures as of December 31, 2020, management has 

concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level. 

Management’s Annual Report on Internal Control over Financial Reporting 

Management is responsible for establishing and maintaining adequate internal control over financial reporting as 
defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control over financial reporting is designed to 
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for 
external  purposes  in  accordance  with  generally  accepted accounting  principles.  Also,  projections  of  any  evaluation  of 
effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

Management has evaluated the effectiveness of our internal control over financial reporting as of December 31, 
2020  using  the  criteria  set  forth  in  the  2013  Internal  Control  —  Integrated  Framework issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission (“COSO”). Based on our evaluation, management has concluded 
that we maintained effective internal control over financial reporting as of December 31, 2020 based on the COSO criteria. 

The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by 
Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which appears in Item 9 of 
this Annual Report on Form 10-K.  

Changes in Internal Control over Financial Reporting 

There were no changes in our internal control over financial reporting identified in connection with the evaluation 
required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended December 
31,  2020  that  has  materially  affected,  or  is  reasonably  likely  to  materially  affect,  our  internal  control  over  financial 
reporting. 

129 

 
 
 
 
 
 
 
 
 
 
 
 
 
Inherent Limitations on Effectiveness of Controls 

Our  management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  do  not  expect  that  our 
disclosure controls or our internal control over financial reporting will prevent all errors and all fraud. A control system, 
no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the 
control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and 
the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, 
no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been 
detected.  These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty,  and  that 
breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual 
acts of some persons, by collusion of two or more people or by management override of the controls. The design of any 
system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no 
assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls 
may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may 
deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may 
occur and not be detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM  

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

Opinion on Internal Control Over Financial Reporting 
We have audited Natera, Inc.’s internal control over financial reporting as of December 31, 2020, based on criteria 
established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (2013 framework), (the COSO criteria). In our opinion, Natera, Inc. (the Company) maintained, 
in all material respects, effective internal control over financial reporting as of December 31, 2020, based on the COSO 
criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (PCAOB), the 2020 consolidated financial statements of the Company and our report dated February 25, 
2021 expressed an unqualified opinion thereon. 

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

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

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

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

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